Shared memory MIMD architecture

Introduction to MIMD Architectures:Multiple direction watercourse, multiple informations watercourse ( MIMD ) machines have a figure of processors that function asynchronously and independently. At any clip, different processors may be put to deathing different instructions on different pieces of informations. MIMD architectures may be used in a figure of application countries such as computer-aided design/computer-aided fabrication, simulation, mold, and as communicating switches. MIMD machines can be of either shared memory or distributed memory classs. These categorizations are based on how MIMD processors entree memory. Shared memory machines may be of the bus-based, drawn-out, or hierarchal type. Distributed memory machines may hold hypercube or mesh interconnectedness strategies.MIMDA type of multiprocessor architecture in which several direction rhythms may be active at any given clip, each independently taking instructions and operands into multiple treating units and runing on them in a coincident manner. Acronym for multiple-instruction-stream.multiple-data-stream.Bottom of Form( Multiple Instruction watercourse Multiple Data watercourse ) A computing machine that can treat two or more independent sets of instructions at the same time on two or more sets of informations. Computers with multiple CPUs or individual CPUs with double nucleuss are illustrations of MIMD architecture. Hyperthreading besides consequences in a certain grade of MIMD public presentation every bit good. Contrast with SIMD. In calculating, MIMD ( Multiple Instruction watercourse, Multiple Data watercourse ) is a technique employed to accomplish correspondence. Machines utilizing MIMD have a figure of processors that function asynchronously and independently. At any clip, different processors may be put to deathing different instructions on different pieces of informations. MIMD architectures may be used in a figure of application countries such as computer-aided design/computer-aided fabrication, simulation, mold, and as communicating switches. MIMD machines can be of either shared memory or distributed memory classs. These categorizations are based on how MIMD processors entree memory. Shared memory machines may be of the bus-based, drawn-out, or hierarchal type. Distributed memory machines may hold hypercube or mesh interconnectedness strategies.Multiple Instruction – Multiple DataMIMD architectures have multiple processors that each execute an independent watercourse ( sequence ) of machine in structions. The processors execute these instructions by utilizing any accessible informations instead than being forced to run upon a individual, shared informations watercourse. Hence, at any given clip, an MIMD system can be utilizing as many different direction watercourses and informations watercourses as there are processors. Although package processes put to deathing on MIMD architectures can be synchronized by go throughing informations among processors through an interconnectedness web, or by holding processors examine informations in a shared memory, the processors ‘ independent executing makes MIMD architectures asynchronous machines.Shared Memory: Bus-basedMIMD machines with shared memory have processors which portion a common, cardinal memory. In the simplest signifier, all processors are attached to a coach which connects them to memory. This apparatus is called bus-based shared memory. Bus-based machines may hold another coach that enables them to pass on straight with one another. This extra coach is used for synchronism among the processors. When utilizing bus-based shared memory MIMD machines, merely a little figure of processors can be supported. There is contention among the processors for entree to shared memory, so these machines are limited for this ground. These machines may be inc rementally expanded up to the point where there is excessively much contention on the coach.Shared Memory: ExtendedMIMD machines with extended shared memory effort to avoid or cut down the contention among processors for shared memory by subdividing the memory into a figure of independent memory units. These memory units are connected to the processsors by an interconnectedness web. The memory units are treated as a incorporate cardinal memory. One type of interconnectedness web for this type of architecture is a crossbar shift web. In this strategy, N processors are linked to M memory units which requires N times M switches. This is non an economically executable apparatus for linking a big figure of processors.Shared Memory: HierarchicalMIMD machines with hierarchal shared memory usage a hierarchy of coachs to give processors entree to each other ‘s memory. Processors on different boards may pass on through inter nodal coachs. Buss support communicating between boards. We us e this type of architecture, the machine may back up over a 1000 processors. In calculating, shared memory is memory that may be at the same time accessed by multiple plans with an purpose to supply communicating among them or avoid excess transcripts. Depending on context, plans may run on a individual processor or on multiple separate processors. Using memory for communicating inside a individual plan, for illustration among its multiple togss, is by and large non referred to as shared memoryIN HARDWAREIn computing machine hardware, shared memory refers to a ( typically ) big block of random entree memory that can be accessed by several different cardinal treating units ( CPUs ) in a multiple-processor computing machine system. A shared memory system is comparatively easy to plan since all processors portion a individual position of informations and the communicating between processors can be every bit fast as memory entrees to a same location. The issue with shared memory systems is that many CPUs need fast entree to memory and will probably hoard memory, which has two complications:CPU-to-memory connexion becomes a constriction. Shared memory computing machines can non scale really good. Most of them have ten or fewer processors.Cache coherency: Whenever one cache is updated with information that may be used by other processors, the alteration needs to be reflected to the other processors, otherwise the different processors will be working with incoherent informations ( see cache coherency and memory coherency ) . Such coherency protocols can, when they work good, supply highly high-performance entree to shared information between multiple processors. On the other manus they can sometimes go overladen and go a constriction to public presentation.The options to shared memory are distributed memory and distributed shared memory, each holding a similar set of issues. See besides Non-Uniform Memory Access.IN SOFTWARE:In compu ting machine package, shared memory is eitherA method of inter-process communicating ( IPC ) , i.e. a manner of interchanging informations between plans running at the same clip. One procedure will make an country in RAM which other procedures can entree, orA method of conserving memory infinite by directing entrees to what would normally be transcripts of a piece of informations to a individual case alternatively, by utilizing practical memory functions or with expressed support of the plan in inquiry. This is most frequently used for shared libraries and for Execute in Place.Shared Memory MIMD Architectures:The distinguishing characteristic of shared memory systems is that no affair how many memory blocks are used in them and how these memory blocks are connected to the processors and address infinites of these memory blocks are unified into a planetary reference infinite which is wholly seeable to all processors of the shared memory system. Publishing a certain memory reference b y any processor will entree the same memory block location. However, harmonizing to the physical organisation of the logically shared memory, two chief types of shared memory system could be distinguished: Physically shared memory systems Virtual ( or distributed ) shared memory systems In physically shared memory systems all memory blocks can be accessed uniformly by all processors. In distributed shared memory systems the memory blocks are physically distributed among the processors as local memory units. The three chief design issues in increasing the scalability of shared memory systems are:Organization of memoryDesign of interconnectedness websDesign of cache coherent protocolsCache Coherence:Cache memories are introduced into computing machines in order to convey informations closer to the processor and hence to cut down memory latency. Caches widely accepted and employed in uniprocessor systems. However, in multiprocessor machines where several processors require a transcript of the same memory block. The care of consistence among these transcripts raises the alleged cache coherency job which has three causes:Sharing of writable informationsProcedure migrationI/O activityFrom the point of position of cache coherency, informations constructions can be divided into three categories:Read-only informations constructions which ne'er cause any cache coherency job. They can be replicated and placed in any figure of cache memory blocks without any job.Shared writable informations constructions are the chief beginning of cache coherency jobs.Private writable informations constructions pose cache coherency jobs merely in the instance of procedure migration.There are several techniques to keep cache coherency for the critical instance, that is, shared writable informations constructions. The applied methods can be divided into two categories:hardware-based protocolssoftware-based protocolsSoftware-based strategies normally introduce some limitations on the cachability of informations in orde r to forestall cache coherency jobs.Hardware-based Protocols:Hardware-based protocols provide general solutions to the jobs of cache coherency without any limitations on the cachability of informations. The monetary value of this attack is that shared memory systems must be extended with sophisticated hardware mechanisms to back up cache coherency. Hardware-based protocols can be classified harmonizing to their memory update policy, cache coherency policy, and interconnectedness strategy. Two types of memory update policy are applied in multiprocessors: write-through and write-back. Cache coherency policy is divided into write-update policy and write-invalidate policy. Hardware-based protocols can be farther classified into three basic categories depending on the nature of the interconnectedness web applied in the shared memory system. If the web expeditiously supports broadcast medium, the alleged Snoopy cache protocol can be well exploited. This strategy is typically used in individual bus-based shared memory systems where consistence commands ( invalidate or update bids ) are broadcast via the coach and each cache ‘snoops ‘ on the coach for incoming consistence bids. Large interconnectedness webs like multistage webs can non back up airing expeditiously and hence a mechanism is needed that can straight frontward consistence bids to those caches that contain a transcript of the updated information construction. For this intent a directory must be maintained for each block of the shared memory to administrate the existent location of blocks in the possible caches. This attack is called the directory strategy. The 3rd attack attempts to avoid the application of the dearly-won directory strategy but still supply high scalability. It proposes multiple-bus webs with the application of hierarchal cache coherency protocols that are generalized or extended versions of the individual bus-based Snoopy cache protocol. In depicting a cache coherency protocol the undermentioned definitions must be given:Definition of possible provinces of blocks in caches, memories and directories.Definition of bids to be performed at assorted read/write hit/miss actions.Definition of province passages in caches, memories and directories harmonizing to the bids.Definition of transmittal paths of bids among processors, caches, memories and directories.Software-based Protocols:Although hardware-based protocols offer the fastest mechanism for keeping cache consistence, they introduce a important excess hardware complexness, peculiarly in scalable multiprocessors. Software-based attacks represent a good and competitory via media since they require about negligible hardware support and they can take to the same little figure of annulment girls as the hardware-based protocols. All the software-based protocols rely on compiler aid. The compiler analyses the plan and classifies the variables into four categories:Read-onlyRead-only for any figure of procedures and read-write for one procedureRead-write for one procedureRead-write for any figure of procedures.Read-only variables can be cached without limitations. Type 2 variables can be cached merely for the processor where the read-write procedure tallies. Since merely one procedure uses type 3 variables it is sufficient to hoard them merely for that procedure. Type 4 variables must non be cached in software-based strategies. Variables demonstrate different behaviour in different plan subdivisions and hence the plan is normally divided into subdivisions by the compiler and the variables are categorized independently in each subdivision. More than that, the compiler generates instructions that control the cache or entree the cache explicitly based on the categorization of variables and codification cleavage. Typically, at the terminal of each plan subdivision the caches must be invalidated to guarantee that the variables are in a consistent province before get downing a new subdivision. shared memory systems can be divided into four chief categories:Uniform Memory Access ( UMA ) Machines:Contemporary unvarying memory entree machines are small-size individual coach multiprocessors. Large UMA machines with 100s of processors and a shift web were typical in the early design of scalable shared memory systems. Celebrated representatives of that category of multiprocessors are the Denelcor HEP and the NYU Ultracomputer. They introduced many advanced characteristics in their design, some of which even today represent a important milepost in parallel computing machine architectures. However, these early systems do non incorporate either cache memory or local chief memory which turned out to be necessary to accomplish high public presentation in scalable shared memory systemsNon-Uniform Memory Access ( NUMA ) Machines:Non-uniform memory entree ( NUMA ) machines were designed to avoid the memory entree constriction of UMA machines. The logically shared memory is physically di stributed among the treating nodes of NUMA machines, taking to distributed shared memory architectures. On one manus these parallel computing machines became extremely scalable, but on the other manus they are really sensitive to data allotment in local memories. Accessing a local memory section of a node is much faster than accessing a distant memory section. Not by opportunity, the construction and design of these machines resemble in many ways that of distributed memory multicomputers. The chief difference is in the organisation of the address infinite. In multiprocessors, a planetary reference infinite is applied that is uniformly seeable from each processor ; that is, all processors can transparently entree all memory locations. In multicomputers, the reference infinite is replicated in the local memories of the processing elements. This difference in the address infinite of the memory is besides reflected at the package degree: distributed memory multicomputers are programmed on the footing of the message-passing paradigm, while NUMA machines are programmed on the footing of the planetary reference infinite ( shared memory ) rule. The job of cache coherence does non look in distributed memory multicomputers since the message-passing paradigm explicitly handles different transcripts of the same information construction in the signifier of independent messages. In the shard memory paradigm, multiple entrees to the same planetary information construction are possible and can be accelerated if local transcripts of the planetary information construction are maintained in local caches. However, the hardware-supported cache consistence strategies are non introduced into the NUMA machines. These systems can hoard read-only codification and informations, every bit good as local informations, but non shared modifiable informations. This is the separating characteristic between NUMA and CC-NUMA multiprocessors. Consequently, NUMA machines are nearer to multicomputers than to other shared memory multiprocessors, while CC-NUMA machines look like existent shared memory systems. In NUMA machines, like in multicomputers, the chief design issues are the organisation of processor nodes, the interconnectedness web, and the possible techniques to cut down distant memory entrees. Two illustrations of NUMA machines are the Hector and the Cray T3D multiprocessor.www.wikipedia.comhypertext transfer protocol: //www.developers.net/tsearch? searchkeys=MIMD+architecturehypertext transfer protocol: //carbon.cudenver.edu/~galaghba/mimd.htmlhypertext transfer protocol: //www.docstoc.com/docs/2685241/Computer-Architecture-Introduction-to-MIMD-architectures

Strengths, Weaknesses of One of the Perspectives of Psychology

Stephanie Graham Psy-201 October 7, 2012 â€Å"What Are The Strengths And Weaknesses Of One Of The Perspectives Of Psychology† Behaviorism is one point of view in psychology directed to a scientific study of the behaviors of man and animal, and is insisted that the cause of our actions and personality lies in our environment, rather than our biology. Behaviorism, also referred to as behavioral psychology, is a theory of learning based upon the idea that all behaviors are acquired through conditioning.Conditioning occurs through interaction with the environment. Behaviorist believe that our responses to environmental stimuli shape our behavior. There are two types of conditioning, classical conditioning and operant conditioning. Classical conditioning was studied by the Russian psychologist Ivan Pavlov, he demonstrated that dogs could learn to associate a neutral stimulus, such as the sound of a bell, with an automatic behavior, such as reflexively salivating to food. He believ ed he had discovered the mechanism by which all behaviors were learned. B. F.Skinner investigated operant conditioning of voluntary and involuntary behavior is a form of learning in which an individuals behavior is modified through its consequences, positive reinforcement, negative reinforcement and punishment. He called his approach to psychology â€Å"radical behaviorism,† where everything a person does, says, and feels constitutes behavior. Even if the behavior is unobservable it can be subjected to experimental analysis. Skinner demonstrated that our social environment is filled with reinforcing and punishing consequences that shape our behavior.For example many people don't enjoy getting up early to go to work every day, but they do it to get the reward: a paycheck. They are being rewarded for good behavior. If some one didn't show up to work, or not call in that person may be fired and not receive a paycheck. This would be a punishment for their behavior. Growing up my parents would tell me that hard work gets good results. Getting straight A's on my report card I received some incentives. If I didn't get into any trouble I received more incentives as well.But if got a bad grade on a homework assignment or test they would take away incentives or any rewards. Without knowing it I grew up on the operant conditioning and adapted it to my daily life where hard work just seemed natural and has some incentives. Weaknesses: Behaviorism examines human and nonhuman beings from the point of view of the behavior they demonstrate. Behaviorism is the understanding of behavior of people and animals in their every movement, emotional response/ reaction, the way they think.Environment plays a great role in the life of people, but it is hard to interpret the behavior of people only focusing on the environmental factor. In some ways behaviorism neglects the individualism of every person making a general behavioral pattern for everybody. A weakness is in Skinners op erant conditioning theory, is the fact that it does not always work. A person can be pretending they stopped the behavior just to receive the reward. If you give a person a reward for good behavior, that person will expect a reward every time.Strengths: One main strength of the behaviorist approach is that it focuses only on behavior that can be observed and manipulated in a controlled environment. Behaviorism tends to predict the behavior in certain circumstances. So having the possibility to predict would give a person the ability to control behavior, avoiding any unnecessary reactions. People are more aware of how to control behavior which has become very important in parenting, and useful when helping kids reactions adapt more socially with others.Behaviorism has helped bring the â€Å"desired outcome† with the help of reinforcement, and punishment. It is a simple concept of behavior using the principals such as classical and operant conditioning. Pavlov's approach aims t o study behavior that is observable and directly measurable. Behaviorism has a tremendous contribution to the development of psychology. As in every perspective approach, study, or theory has its advantages, disadvantages, strengths and weaknesses. What works for one person may not work for another.But it is just as important in helping people. Skinner and Pavlov both had great techniques in trying to recognize, predict, and control behaviors. Both have their strengths and weaknesses. You could say the Pavlov's theories were groundbreaking in a sense however even under favorable conditions however a person and especially an animal cannot be expected to do the exact same thing every time regardless of a like result. Variable change always has to be accounted for. Such as lack of interest or tiredness.Skinner was on a better tract in my opinion with the rewarding/punishment of behavior. Some issues could arise there as well such as the interpretation of rewards by the individual and j ust like Pavlov you would have to change them or interest would be lost after eventually. Depending on circumstances both seem very applicable on a case by case basis both having their strengths and weaknesses both very valid points but must be determined by what is to be achieved and who it is being done on.

John Donne and Reformation

John Donne was born in Bread Street, London in 1572 to a prosperous Roman Catholic family – a precarious thing at a time when anti-Catholic sentiment was rife in England. His father, John Donne, was a well-to-do ironmonger and citizen of London. Donne's father died suddenly in 1576, and left the three children to be raised by their mother, Elizabeth, who was the daughter of epigrammatist and playwright John Heywood and a relative of Sir Thomas More. [Family tree. ] Donne's first teachers were Jesuits. At the age of 11, Donne and his younger brother Henry were entered at Hart Hall, University of Oxford, where Donne studied for three years. He spent the next three years at the University of Cambridge, but took no degree at either university because he would not take the Oath of Supremacy required at graduation. He was admitted to study law as a member of Thavies Inn (1591) and Lincoln's Inn (1592), and it seemed natural that Donne should embark upon a legal or diplomatic career. In 1593, Donne's brother Henry died of a fever in prison after being arrested for giving sanctuary to a proscribed Catholic priest. This made Donne begin to question his faith. His first book of poems, Satires, written during this period of residence in London, is considered one of Donne's most important literary efforts. Although not immediately published, the volume had a fairly wide readership through private circulation of the manuscript. Same was the case with his love poems, Songs and Sonnets, assumed to be written at about the same time as the Satires. Having inherited a considerable fortune, young â€Å"Jack Donne† spent his money on womanizing, on books, at the theatre, and on travels. He had also befriended Christopher Brooke, a poet and his roommate at Lincoln's Inn, and Ben Jonson who was part of Brooke's circle. In 1596, Donne joined the naval expedition that Robert Devereux, 2nd Earl of Essex, led against Cadiz, Spain. In 1597, Donne joined an expedition to the Azores, where he wrote â€Å"The Calm†. Upon his return to England in 1598, Donne was appointed private secretary to Sir Thomas Egerton, Lord Keeper of the Great Seal, afterward Lord Ellesmere. Donne was beginning a promising career. In 1601, Donne became MP for Brackley, and sat in Queen Elizabeth's last Parliament. But in the same year, he secretly married Lady Egerton's niece, seventeen-year-old Anne More, daughter of Sir George More, Lieutenant of the Tower, and effectively committed career suicide. Donne wrote to the livid father, saying: â€Å"Sir, I acknowledge my fault to be so great as I dare scarce offer any other prayer to you in mine own behalf than this, to believe that I neither had dishonest end nor means. But for her whom I tender much more than my fortunes or life (else I would, I might neither joy in this life nor enjoy the next) I humbly beg of you that she may not, to her danger, feel the terror of your sudden anger. 1 Sir George had Donne thrown in Fleet Prison for some weeks, along with his cohorts Samuel and Christopher Brooke who had aided the couple's clandestine affair. Donne was dismissed from his post, and for the next decade had to struggle near poverty to support his growing family. Donne later summed up the experience: â€Å"John Donne, Anne Donne, Undone. † Anne's cousin offered the couple refuge in Pyrford, Surrey, and the couple was helped by friends like Lady Magdalen Herbert, George Herbert's mother, and Lucy, Countess of Bedford, women who also played a prominent role in Donne's literary life. Though Donne still had friends left, these were bitter years for a man who knew himself to be the intellectual superior of most, knew he could have risen to the highest posts, and yet found no preferment. It was not until 1609 that a reconciliation was effected between Donne and his father-in-law, and Sir George More was finally induced to pay his daughter's dowry. In the intervening years, Donne practised law, but they were lean years for the Donnes. Donne was employed by the religious pamphleteer Thomas Morton, later Bishop of Durham. It is possible that Donne co-wrote or ghost-wrote some of Morton's pamphlets (1604-1607). To this period, before reconciliation with his inlaws, belong Donne's Divine Poems (1607) and Biathanatos (pub. 1644), a radical piece for its time, in which Donne argues that suicide is not a sin in itself. As Donne approached forty, he published two anti-Catholic polemics Pseudo-Martyr (1610) and Ignatius his Conclave (1611). They were final public testimony of Donne's renunciation of the Catholic faith. Pseudo-Martyr, which held that English Catholics could pledge an oath of allegiance to James I, King of England, without compromising their religious loyalty to the Pope, won Donne the favor of the King. In return for patronage from Sir Robert Drury of Hawstead, he wrote A Funerall Elegie (1610), on the death of Sir Robert's 15-year-old daughter Elizabeth. At this time, the Donnes took residence on Drury Lane. The two Anniversaries— An Anatomy of the World (1611) and Of the Progress of the Soul (1612) continued the patronage. Sir Robert encouraged the publication of the poems: The First Anniversary was published with the original elegy in 1611, and both were reissued with The Second Anniversary in 1612. Donne had refused to take Anglican orders in 1607, but King James persisted, finally announcing that Donne would receive no post or preferment from the King, unless in the church. In 1615, Donne reluctantly entered the ministry and was appointed a Royal Chaplain later that year. In 1616, he was appointed Reader in Divinity at Lincoln's Inn (Cambridge had conferred the degree of Doctor of Divinity on him two years earlier). Donne's style, full of elaborate metaphors and religious symbolism, his flair for drama, his wide learning and his quick wit soon established him as one of the greatest preachers of the era. Just as Donne's fortunes seemed to be improving, Anne Donne died, on 15 August, 1617, aged thirty-three, after giving birth to their twelfth child, a stillborn. Seven of their children survived their mother's death. Struck by grief, Donne wrote the seventeenth Holy Sonnet, â€Å"Since she whom I lov'd hath paid her last debt. According to Donne's friend and biographer, Izaak Walton, Donne was thereafter ‘crucified to the world'. Donne continued to write poetry, notably his Holy Sonnets (1618), but the time for love songs was over. In 1618, Donne went as chaplain with Viscount Doncaster in his embassy to the German princes. His Hymn to Christ at the Author's Last Going into Germany, written before the journey, is laden with apprehension of death. Donne returned to London in 1620, and was ap pointed Dean of Saint Paul's in 1621, a post he held until his death. Donne excelled at his post, and was at last financially secure. In 1623, Donne's eldest daughter, Constance, married the actor Edward Alleyn, then 58. Donne's private meditations, Devotions upon Emergent Occasions, written while he was convalescing from a serious illness, were published in 1624. The most famous of these is undoubtedly Meditation 17, which includes the immortal lines â€Å"No man is an island† and â€Å"never send to know for whom the bell tolls; It tolls for thee. † In 1624, Donne was made vicar of St Dunstan's-in-the-West. On March 27, 1625, James I died, and Donne preached his first sermon for Charles I. But for his ailing health, (he had mouth sores and had experienced significant weight loss) Donne almost certainly would have become a bishop in 1630. Obsessed with the idea of death, Donne posed in a shroud – the painting was completed a few weeks before his death, and later used to create an effigy. He also preached what was called his own funeral sermon, Death's Duel, just a few weeks before he died in London on March 31, 1631. The last thing Donne wrote just before his death was Hymne to God, my God, In my Sicknesse. Donne's monument, in his shroud, survived the Great Fire of London and can still be seen today at St. Paul's.

The issue of national or international importance which have an impact Essay

The issue of national or international importance which have an impact on society - Essay Example This research tells that terrorism has had a lasting impact on the society in more ways than one. It must be understood here that there are only negatives attached with terrorism and absolutely no positives could be drawn from such a heinous issue. The wave of terrorism sparked much debate and controversy after the 9/11 attacks on the US soil. After this, the world scenario started to change for the worse, so much so that terrorism seems to be the only constant amongst the different international issues of the current times. This essay discusses that the turn of the new century has meant nothing else but sheer terrorism with terrorist activities breaking headlines with each passing day, in different regions of the world. Taliban and Al Qaeda have been credited with most of these terrorist activities and there is enough evidence to suggest that these two outfits have brought much harm to the ranks of global peace and sanity than any other terrorist wing. In the coming times, terrorism will continue to pose as a major problem. It will haunt the lives of the people and destruct their property and wealth just like it is doing in the present times. It does not guarantee peace to prevail in the near future. The world is plunged into a fighting zone, with non-state actors fighting it out for their own ulterior motives. Some state-level terrorism is also being given air and this has meant disaster and nothing else in the long run.

Roman Empire Essay Example | Topics and Well Written Essays - 500 words

Roman Empire - Essay Example At the same time, there was high inflation at the empire, and its economy was deteriorating. The state was under constant threats of bankruptcy because its inhabitants resisted sharing the empire’s wealth. Large amounts of gold were sent to the orient to cater for luxury goods that led to a decline on the gold available to make coins. Its currency devalued, and people had to return bartering system of trade (â€Å"IHA†). The empire also had heavy military spending. Its constant wars saw the army overstretched, and it started recruiting the conquered barbarians and other foreign mercenaries. The barbarians later joined up with outside forces to fight the empire. At one time, the Roman soldiers were moved to fight in Italy civil wars leaving their borders with little resistance to German mercenaries (â€Å"IHA†). The period ranged approximately 80 BC to 20 AD. During this period, the Latin Language was perfected as a literary medium. Some of the main and outstanding Latin masterpieces were composed during this period. In it, the Ciceronian Period lasted from 70 BC to 42 BC, and was dominated by Marcus Tullius Cicero. The second was between 43 BC and 20 AD named as the Augustan Age. It featured writers such as Livy, Horace, and Virgil (Spielvogel, 152). The period ran from 500 BC to 330 BC. It was a great age for arts and literature. Some of the notable figures in this period were Greek dramatists such as Aristophanes and Euripides. They were also influential poets such as Ovid and Horace (Spielvogel, 89-100). The period was between 800 BC and 500 BC. Literature from this period includes earliest texts that have preserved as manuscripts. The period marked immaturity both in language and art. Poetry dominated the period with notable figures such as Pacuvius, Ennius, and Accius. Literature also drew from the traditions of other communities’ cultures such as Greece (Spielvogel, 67-79). Roman architecture was inspired by

Mental models Essay Example | Topics and Well Written Essays - 1000 words

Mental models - Essay Example Basically, these mental models are ideas and beliefs that people instinctively or intentionally acquires from their experiences and which consequently influence their behavior and mindset (Uitdewilligen, Waller, & Pitariu, 2013). These images of recognized reality inform individuals of cause and effect, and push them to predict specific outcomes, interpret occurrences, and prompt them to act in specific ways. However, mental models can be both an advantage and a disadvantage, particularly with regard to perceiving other people. This essay discusses how mental models both assist and limit an individual’s perception of people they will meet for the first time. Individuals all have assumptions about other people. These assumptions guide individuals in a variety of ways. They assist individuals in anticipating and interpreting the behavior of other people. Assumptions about others are also helpful when an individual has to give a description of another person. Yet, the main import ance of a mental model is its capacity to help individuals conduct their interactions with other people (Young, 2011). People’s assumptions about other people have significant impact in their daily lives. ... In the real world, people obviously do not have the luxury of time to get to know all the people they meet personally. According to Senge (2010), mental models help individuals make decisions and anticipate how other people will act in specific circumstances instantly. The usefulness of mental models becomes pronounced in a culturally diverse organization (Matteson, 2013). For instance, a senior executive in a multinational company is urgently looking for a new project manager. The applicants come from different racial backgrounds, and the senior executive is assigned to interview each of these applicants. He is meeting all these applicants for the first time. His mental models of various racial groups will definitely influence his choice. These mental models will guide his decision of who to hire for the position of project manager. Mental models are valuable tools in unfamiliar situations and circumstances requiring quick decisions. These mental models can also be useful in instanc es where an individual will be meeting another person from a different culture. These mental models may guide an individual’s behavior or attitude toward another person. Having an assumption of one’s culture helps create a meaningful and respectful interaction between individuals of different cultures (Lundquist & Jarvella, 2000); for instance, if person A, an Australian, will meet person B, a Japanese, for the first time it would be helpful if person A assumes that Japanese, unlike Australians, are not straightforward people. This assumption will help person A conduct a harmonious, polite conversation with person B. Even in business negotiations, mental models of individual characteristics and culture may help resolve conflict and make personal and cultural

Project management Essay Example | Topics and Well Written Essays - 750 words - 8

Project management - Essay Example The network diagram below illustrates the sequence of the Foundry project that is due to be completed within 25 weeks. This shows the sequence of different activities that will be undertaken. This constitutes project management that is commonly known as careful management of all the activities involved in a particular project (Burke, 2010). Project planning is also required in order to carry out all the activities and tasks successfully. This helps the people involved in the project to achieve the desired goals in undertaking the work. 2. The critical path in the project shows the longest sequence of events that should be completed on time in order to meet the project schedule with regards to its completion (Business Dictionary, 2015). Accordingly, each sequence that constitutes a critical path should be commenced after the completion of the predecessor. In some cases, these critical paths can be carried out simultaneously after the completion of the predecessor. In the diagram shown above, there are mainly three critical paths. The first one being pouring concrete and installing frame which ought to be carried out after implementing the first two components in the project. This path should take four weeks and effort should be made to ensure that it goes according to schedule in order to avoid delaying the project. The other important critical paths include building high temperature burner and installing air pollution device which take four and five weeks respectively. These activities should be completed within t he set time frame in order to ensure that the project is not delayed.

Key issues to consider when designing for people with disabilities Essay

Key issues to consider when designing for people with disabilities - Essay Example ‘People with disabilities have historically been marginalised in education, employment and community living’ (Key, 2001). This sector must be recognized as having potential to success, hand in hand with the rest of the population and having the ability of contributing substantially to the overall development of the society and nation as a whole. The rapid advancement of technology has facilitated a wide ranging scope of enabling the people with disability, giving them a strong platform to prove that they are not disabled but differently abled persons, under different circumstances, whose potential when fully exploited, can make a visible impact on the socio-economic scenario of the nation. The various enabling factors, facilitated by the emerging technologies, especially in the field of computers and information technology, have proved a milestone in the lives of the people with disabilities. They have restored the faith in the vast potential that was hitherto hidden and provided them with a means to achieve socio-economic independence, giving them self respect and a future to look forward to. It is therefore, no wonder that computers have been considered as one of the most important inventions of the century. Sensitization is a very important tool in creating appropriate atmosphere that would promote and inculcate the concept of equality and an innate sense of expectation from this sector as is the normal practice. To achieve this objective, necessity of the hour is designing a computer system that would promote the cause of enabling the persons with disability so that they can gain self respect by becoming financially independent. Hence the key issues that must be taken into account while designing and developing the system constitute very important aspect of the system itself. The following issues may be considered as highly relevant to the design and development of computer system which would

Personal Statement Example I may not be the brightest student, but I have always been especially proud of the dedication and fervor I possess for my study and work. My parents were an inspiration for me in my selection of area of study due to the fact that they are businesspeople. They are both engaged in business activities. I was exposed to the business world since a very young age. For me the study of business has been a very rewarding experience. My job experience includes doing auxiliary accounting work at my sister’s jewelry store. I was responsible for preparing the all four major accounting statements which include the income statement, balance sheet, statement of retained earnings, and statement of cash flow. At this job I was exposed to the entire accounting cycle. Two of the extracurricular activities that I have done during my tenured at University of Keele include Ping Pong Society and Start Britain Up which is business investment club. I have successfully organized many extra-curricular ac tivities. For example, I organized a ping pong society that has been profitable in University of Keele. There are lots of international students in my society. I also got lots of friends from different countries that speak different languages such as English, Spanish and Japanese. Being surrounded by a diverse group of people helped me improve my creativity, networking abilities and people skills. I’ve successfully organized ping pong matches twice. I learned how to coordinates different activities using theories from class. During my time at University of Keele I joined the club Start Britain Up. This club will invest in your concepts if a person has a good idea. I proposed an idea about a new toilet paper. My idea was to put liquid medicine ink on the toilet paper. Doing so can treat anal itching due to the liquid medicine. Even thought the idea did not get funded because it brought more pollution to the environment than regular toilet paper, I will continue to try to bring new ideas to market in the future. I am applying to study a master’s degree in business administration in either accounting, finance, management, or marketing. I selected the University of Queen Mary as my top choice because this academic institution has a great reputation. University of Queen Mary has an excellent business program. The school has a good environment and a good location. It’s located near London, the biggest city in the United Kingdom. I’m eager to start the next phase in my education by becoming a graduate student of business at University of Queen Mary. I’m an excellent candidate for the business graduate program. During my lifetime I’ve demonstrated that I am a hard working and dedicated student. I have excellent communication skills, analytical skills, and teamwork capabilities. In the business environment of the 21st century it is of utter importance to be able to work well with other employees. My desire to pursue a graduate degree occurred because I realize that the business world has become more competitive than ever before in the past. To be able to compete in the job market a professional has to pursue better educational credentials. One of the goals in the future upon graduation is to reach the managerial level. It will be easier for me to become a manager if I have a master’s degree in business. An MBA can help me greatly because I will learn how to solve complex business program, analyze vast amounts of data, and

A Review of Bathing Beauties Essay Example for Free

A Review of Bathing Beauties Essay Anna Schnur-Fishman presents a compelling argument for teaching healthy body image and self esteem in her article â€Å"Bathing Beauties†. Set in the communal shower of a summer camp, Schnur-Fishman described how she and her friends developed their positive body image. Through group support and open conversations, the girls who showered in the communal shower and learned that beauty was not what they saw on TV or on a billboard. In fact, they learned that no one really looked like those images. And through this communal showering the girls learned to love their bodies and all their imperfections. These experiences and lessons were such that Schnur-Fishman and her friends have carried then throughout their lives. Anna Schnur-Fishman makes several interesting and valid points in favor of the communal showering in the BIK. First she discussed the idea of community support. According to Schnur-Fishman, everyone had to shower together, so no one was judgmental of another’s bodies. In fact, Schnur-Fishman, discussed one conversation where all the girls said out loud one thing they did not like about themselves. As a friend of the author’s stated, she never noticed the flaws the other girls. The realization showed her that if she was not paying attention to others flaws, others were not paying attention to hers. This exercise instilled in them that girls can feel beautiful no matter what they may think is wrong with their bodies. This is a beautiful idea because, as Schnur-Fishman notes, outside American culture often does not provide young girls this type of support. Instead, our culture, more than any other, pushes an unrealistic image of female beauty. Schnur-Fishman continued to discuss the idea of multigenerational exposure. At peak shower times, the age range in the shower could be from 8-25 years old. This allowed for the older girls to really be role models for the younger girls. In today’s culture, young girls look up to actresses and models, these images do nothing but further warp a girl’s sense of self and body image. Following in line with this idea, the author stated that the BIK was â€Å"a reality check†. Again, no one is perfect. The only way for a young girl to learn this is to see that others have flaws and no one really pays them any attention. Schnur-Fishman also stated that she believed the communal shower was a way to â€Å"push back against American culture†. By feeling good about oneself and not being ashamed, a girl has power over what the mainstream culture is trying to teach her. She mentioned that how good they felt should have been criminal. Schnur-Fishman made a valid point here because it often does seem very unacceptable for a female to feel good about herself. Find a group of females and listen to their conversation. Chances are you will hear them complain about how bad they look or how fat they feel. You can almost guarantee that if one of the females said something positive about themselves, she would get the cold shoulder or some negative response from the others (eyes rolling, fake, shallow agreement, talking behind her back when she goes to the bathroom, etc). The last point the author discussed was the joy she felt in the BIK. She stated that it was liberating, being free and remembering what is was like before she cared about her body. It gave her and the other girls the chance to relax and let loose. They did not have to try to up hold any type of image. I think the Schnur-Fishman made some very good points. It is unfortunate that even in today’s culture, were we say we promote healthy living and encourage self esteem, so many girls suffer. The images we show our young girls and the words we say contradict each other, only confusing ours girls into personally insecurities. We tell them to love them selves no matter what they look like. Then we show them that beauty is comes in tall and skinny package, with clear skin. This unrealistic body image is causing more emotional and health related problems among our young girls than sometimes we care to realize. Giving our young girls opportunities to feel good about them self is only the first step to reclaiming their own personal power.

Evidence Based Healthcare Research Social Work Essay

Evidence Based Healthcare Research Social Work Essay Evidenced Based Healthcare and Research: Appraisal. In the United Kingdom the concept of Independent Living and Self-directed Support has become an established approach for the delivery of health and social care services, that it is currently the preferred residential alternative for people with learning disabilities (Binnie Titchen 1999). Independent living can be defined as enabling independence by receiving the right support how and when it is required (Morris 2004). It has now become a key principle in various government policy documents such as the Valuing People Now Strategy (UK Department of Health, 2009) and the Personalisation through Person-Centred Planning initiative (UK Department of Health, 2010). This assignment aims to present a detailed critique of a qualitative study entitled How adults with learning disabilities view independent living (Bond Hurst 2010). A critique can defined as a balanced evaluation of the strengths and limitations of a research article, in order to determine its credibility and/or applicability to practice (Gamgee 2006). This study is a welcome contribution to the current health and social care research domain because whilst independent living is the preferred residential option, it is not at all clear whether it is suitable for all people with learning disabilities, moreover if there is in fact sufficient empirical evidence to support this notion. It is therefore imperative to establish a sound evidence base that draws upon the lived personal experiences of those with learning disabilities. Using an acknowledged framework A Step by Step guide to critiquing a quantitative study (Coughan et al., 2007) the relative worth of the evidence in support of i ndependent living will be judged systematically. As well as exploring the significance of independent living as an essential nursing intervention and its application to modern clinical practice. Ryan-Wenger (2003) suggests that in analysing published articles it is important to ascertain two fundamental aspects of a critique which can be subdivided into elements that influence the robustness of the research methodology also known as integrity variables and elements which influence the believability of the research such as writing style, author(s), report title and abstract otherwise known as credibility variables. The latter seems to be the most logical place to commence. Evaluation of the Journal Article Polit and Beck (2006) state that writing style should be such that it attracts the reader to read on; this paper is well written, comprehensive and concise. The structure and layout of the paper is well organised with a logical consistency and free from jargon in comparison to some papers where the author(s) can be opaque in their approach. However slight reservation is reserved concerning the level of proof reading as there seems to be some grammatical and typographical errors which can be found on pages 288 and 289. Both authors appear to have a sound background in learning disability from both a social context and educational settings. As indicated in the acknowledgements the authors qualifications indicate that they have a degree of knowledge in this field and this piece of research seems to be a part of a taught component of their masters programme. The report tile seems to be descriptive and succinct, although it lacks specificity of the research methodology used in the study. This can be very useful for others who are searching for this type of paper. Although the term qualitative research is mentioned under keywords the title itself could be more specific. As a result the report title is ambiguous and merely eight words in length. Meehan (1999) states that a title should be between ten to fifteen words long in order to clearly identify the purpose of the study for the reader. This paper presents both an accessible and detailed version of the abstract, but are both helpful? The accessible form includes information on the subject and the number of participants, whereas the detailed form provides an outline of the methodology used, ethical framework, findings and recommendations. On balance the summaries present a clear overview of the study, however it does beg the question in what sense is the accessible form accessible? and to whom? It seems that the authors are trying to be politically correct rather than logical because how many service users actually read the British Journal of Learning Disabilities?. It seems that this is a knee jerk reaction which has been applied incorrectly; it would be more suitable if the document was aimed at informing an audience with learning disabilities such as Valuing People (UK Department of Health, 2001) which caters to a wide range of readers. The easy -read version is aimed at service users whilst the denser version is aimed at professionals and service providers. Having identified and analysed variables that affect the credibility of the research presented, how believable the work appears, the authors qualifications and their ability to undertake and accurately present the study. The robustness of the research methodology and the integrity of the findings will be appraised in order to determine the trustworthiness of the study and its applicability to nursing practice. The authors state the aim of the study is to explore the views of nine people with learning disabilities who have already achieved independence and wish to contribute to the debate of independent living. The authors suggest that this style of living is now viewed as desirable, but what is the reality for people who live with learning disabilities? This concept of desirability is held as problematic by the authors who choose to study and present the reality of living independently as opposed to the notion of general and conventional wisdom. A study conducted by Barlow Kirby (1991) concluded that people in receipt of self-directed support had more life satisfaction than those in residential care. This finding is further supported by the publication of Independent Living (HM Office for Disability Issues, 2007). The decision to suspend judgement about independent living is justifiable and is supported by other researchers in the field of learning disabilities; as there are several impli cations for service users, professionals and service providers. This is for a number of reasons for instance promoting choice and control (OBrien, 2002), health issues (Priest Gibbs, 2004), vulnerability (Cooper, 2002) and the ability for those with learning disabilities to access services (Jansen et al., 2006). The literature review conducted by the authors demonstrates an appropriate depth and breadth of reading around independent living. The majority of studies included are of recent origin being less than five years old; the few historical studies included put the concept of living independently into context. The authors successfully identified conflicts between the literature by comparing and contrasting findings (Burns and Grove., 1997), because although evidence exists to show people who have moved from larger institutions prefer smaller group homes (Forrester-Jones et al., 2002) there is still no accurate data detailing the number of people with learning disabilities living independently (Beadle Brown et al., 2004). However the authors failed to mention how they conducted their search and information on the databases used to gather papers in their review. The authors did however, use primary sources of information as opposed to secondary sources and anecdotal information, which attes ts to the integrity and value of the study presented. Bond Hurst (2010) ascertained the narratives of nine people with learning disabilities via the use of semi-constructed interviews within their methodology. The authors are to be commended for their attention to detail in terms of their ability to design and structure interviews so as to accommodate the needs of the participants. As well as conducting interviews at times and venues convenient to them. The interview structure included open-ended questions to assist understanding as communication emerged to be a key barrier for some people with learning disabilities. The authors report on a number of theoretical issues that have been adapted for the participants in order that they might fully participate in the research process. The structure of the interviews was devised using the Canadian Model of Occupational Performance (Canadian Association of Occupational Therapists, 1997), but is this model applicable to the United Kingdom population and to which care setting? Bond Hurst (2010) adopted thematic analysis within their methodology in assessing the narratives. The data collected was audio taped and later transcribed into coded themes, which is acknowledged in general research literature to be good practice. On balance, the authors adhered to the steps in the research process and it is conveyed between the fluidity of phases. The critique subsequently moves onto considering the ethical framework. This research paper was supported by the local ethics committee and all participants in the study gave informed consent. Although it is not clear whether or not it was an National Health Service (NHS) ethics committee. However, the authors sought to ensure their working methods complied with the Data Protection Act (1998) but not with all government legislation applicable to the study such as the Mental Health Act (1983). Although there is mention about accessibility, the authors failed to ensure the participants had the capacity to make informed decisions as defined in the Mental Health Act (1983). In relation to the number of participants, the sample size is small and therefore may not be reflective or wholly representative for all people with learning difficulties. Small samples are more likely to be at risk of being overly representative of small subgroups within a target population (Coughan et al., 2007). Th erefore slight reservation is held as the authors did not mention whether they sought to remove overall bias by generating a sample that is likely to be representative and generalisable to the target population. Parahoo (2006) states that for a sample to truly reflect of the population it represents the authors must generate a probability sample. The participants in this study were recruited via convenience sampling using a third party (Melton 1998); however several variables could have an affect on the sample which can lead to it being distorted such as the vast age range. The authors are to be commended however, in their efforts to maintain the confidentiality of their participants by offering them the choice to provide their own pseudonyms. In the discussion the authors identified seven themes from their data analysis which reflected the views of all the participants and in turn addressed the aims of the study. Their findings supported the four key principles as stated in the Valuing People policy document, and ways in which people can be supported to achieve this includes increasing social inclusion, increasing autonomy and choice for people and raising awareness of the vulnerability of those with learning disabilities. However the study also highlighted that the majority of participants struggled with the more complex aspect of living independently, such as money management and budgeting. The government has recently introduced Direct Payments as part of a nationwide transformation in social care services, which involves paying money directly to an individual in need to take control of their own support and care services. This initiative will aid finance management as it enables service users to have control over the c are they receive and how they receive it. The majority of participants maintained that when comparing their current lifestyle of independent living to that of their previous lifestyle it was clear that they wanted to remain living independently. Application to Clinical Practice This section will explore the significance of independent living as an essential nursing intervention and its application to modern clinical practice. Gates Atherton (2001) state that there is a need for evidence of effectiveness in health and social care. The most important aspect of being a practitioner regardless of ones vocation, is that collectively we as professionals seek the best evidence available on which to base our practice (Coughan et al., 2007). The evidence in support of independent living is limited and not entirely accurate, therefore when evidence is presented it should not be taken on face value. As Cullum Droogan (1999) put it not all research is of the same quality or high standard therefore as a learning disability nurse and social worker it is important being a care provider that although a paper has been published it can be critically appraised. This paper is of central relevance to our practice in ensuring that the lifestyles of people with learning disabil ities are informed by valid and reliable evidence. This research paper adds value to the current literature available in support of independent living however caution must be expressed as it is not solely about living independently. The concept of independently living cannot be advocated for everyone; each person is different and therefore require different levels of support which will meet their needs. The publication of Valuing People (UK Department of Health, 2001) the key document that prompted a change in the way health and social care services operate. The paper made Person-Centred Planning a central component of service reform, and outlined four key principles namely: Human Rights, Independence, Choice and Social Inclusion (Mansell and Beadle-Brown, 2004). This means that people with learning disabilities should be valued members of society, treated with dignity and respect whilst having the same rights and choices as everybody else (OBrien, 2002). Furthermore, people with le arning disabilities should feel empowered to take control over the care that they receive in order to plan and live their lives independently. Previously, people with learning disabilities were shunned away from the community and susceptible to abuse. The Community Care Act (1990) was introduced as a result of both political and social changes in attitudes towards the treatment of people with mental illnesses. In line with Mental Health Act (1983) the aim was to remove the stigma associated with mentally ill people away from isolation towards social inclusion (Social Role Valorisation, Wolfensberger, 1983). But does independently living mean that you get social inclusion? Currently we are seeing a culture of people who require support being effectively excluded from society, waiting for the next support worker to cook their meals, help with personal hygiene and general cleaning. This is a downward spiral in our society which is putting a demand on our system. As a care provider in line with the General Social Care Council and the Nursing and Midwifery Codes of Conduct (2008), it is our duty to advocate in the best interest of the client at all times but who is actually making the decisions? Bond Hurst (2010) highlighted how closely health was linked to independent living and that many of the participants suffered from chronic conditions such as asthma, diabetes and arthritis. Is it a case of compromising funding for services at the expense of overlooking health issues? It seems that the authors make a plausible case that people with learning disabilities are being seen as not a priority as they carry a disproportionate burden of health inequalities among our population. The reality for people with learning disabilities is far from the projected lifestyle of independence (Emerson UK Literature). It is a challenge to support people with learning disabilities, several factors need to be considered to prevent potential disregard. Jansen et al., (2006) points out the need to adopt integrated care approaches in treating those with learning disabilities. This will involve working with different agencies (interagency team working) and different types of professionals (multidis ciplinary team working) in order to provide an holistic service to meet their needs. Current research shows that a disabled person is likely to be in contact with at least ten different care professionals in their lifetime (UK Department of Education, 2003). Issues can arise through out this time which may lead to lack of continuity and communication. Therefore, a sufficient amount of training and awareness is needed to ensure that all staff are qualified and skilled to ensure equity of service provision. When caring for patients it is essential as a practitioner to adopt the current best practice. To determine what this is one must be able to critically appraise evidence that is presented to them (Basset and Basset., 2003). This paper focused on the lived experiences of nine people with learning disabilities about the reality of living independently. In critiquing this paper, the authors successfully highlighted the importance of independent living as an essential nursing intervention however there were also some limitations, the most important being limited verification of the data. Furthermore the narratives of the participants were highly subjective and findings non-generalisable, thus the notion of independent living is not to be applied to all that have a learning disability, or vulnerable adults with complex needs. As recommended by the authors, further accurate, reliable and valid research is needed that will add value to the evidence-base domain. Total Word Count: 2,452 Excluding Headings and References

How does Smoking effect human lungs, causes cancer and even death

How does Smoking effect human lungs, causes cancer and even death Scientific Research Skills Assignments How does Smoking effect human lungs, causes cancer and even death? Literature Review Smoking stands for intake of tobacco or other related substances either for leisure or in severe cases as an addiction. Smoking is behavior which is reprimandable and highly non acceptable because it not only bring harms to the one who inhales it but to the one who live around him or her including the environment. Addressing the topic of smoking and spreading its proper awareness is very important. This report illustrate dangers of smoking and its effects on one’s mental, physical and psychological wellbeing. Additionally this report will deal with effect of smoking on demographic variation, socio-economic determinants and cognitive factors which are involved in smoking and related behaviors and their impact Approximate age at which people start smoking is 15 in almost each country. Smoking which might start as a fun activity with friends becomes addiction if prolonged. Young people in their early teenage are the biggest victims of smoking and they become regular smoker till their early twenties. Excessive and addictive smoking from such early age increase the danger of early death and other highly risk full diseases. It becomes clear then that adolescents and young adults are the sole and important target of this evil hence they must be given proper awareness to be protect and prevent them to step toward this self-destruction. Doctors can be one important mean of communicating this danger to the target group of this evil but first of all peer can effect each other a lot. Young adults and teenagers take up smoking because of their social relationships and their psychological states, it is important to understand each individual and why they took up smoking. Sometimes young people think t hemselves of no worth or useless so they take up this down trodden road and sometimes conflicts at home or at school and college may lead to such dangerous situations. Relationships at house can also be the trigger as well as bullying. Many people are not aware or not properly aware with the working of nicotine and addictive nature of smoking. Family, peers, doctors, family physicians can play a central influential role of informing the smokers about the hazards of smoking and where it might lead them. Sometimes family is ignorant and does not care what one is doing out of home so in such cases parents and family need counseling as well to be cautious and careful about the habits and activities if their family members. Smoking cigarette causes many diseases and initial ones can be cough and phlegm production leading to severe respiratory illness (Morris. C, 1990). Inhale the smoke, take them as vaporizer or brew them into tea; tobacco, marijuana, hashish once into the body will affect every organ of the body, brain, nervous system and the central immunity system. Smoker feels instant changes and reactions in the body which stops after 2 to 3 hours. It effects heart, results in low blood pressure and also the blood sugar level is affected (Ratini, MDweb Medical Reference, 2014). Excessive smoking can cause cancers and other dangerous diseases. It starts by irritation and coughing and leads to lung cancer and in severe cases ends at death (Ratini, MDweb Medical Reference, 2014). Tobacco and tobacco products are responsible for approximately 3 million deaths across the world that makes it 6% of all deaths. It is believed that deaths by tobacco and tobacco products are going to increase more than 10% by a decade and will exceed 20% in developing countries (WHO, 2011). There is no second thought to the fact that smoking effects lungs primarily either one is a long term smoker or smoked for few times. Level of lung functioning is too low in people with the habit of smoking as compared to people who do not smoke and this functioning keep on decreasing with the ongoing habit of smoking. Smoking effects lungs and its working but symptoms may appear later and when the diseases is recognized, it is usually too late to be cured. Smoking not only causes cancer but other lung related chronic diseases as well (Spitzer, 2001). Tobacco smoke has several different harmful particles and chemicals that causes irritation and inflammation in the respiratory tracts and lungs. When such potentially harmful substances are inhaled by a smoker, body reacts to them and releases mucus and coughing to clear them. Very smoker suffer from a morning attack of severe coughing which happens from several reasons. Human lungs contain tiny hair like extension called cilia which push and clean the potentially injurious material out of lungs but the tobacco smoking interferes with the working of cilia and effecting their sweeping action of harmful substances so consequentially much of the harmful substances stay in the lungs causing mucus discharge and inflammation of the respiratory tracts as well. So when smokers are sleeping or they aren’t smoking, cilia continues with their normal function of cleaning the harmful substances out of lungs and when smoker wake up, lungs are busy in trying to remove the particles and mucus built up a day before (questions about smoking and health, 2014) . Working of cilia stops after prolonged exposition to smoke hence lung is unable to sweep out the harmful substances and become vulnerable to many infections and irritation causing mucus and cough. This smoker cough is the early precursor to further chronic disease like COPD, chronic bronchitis, lung cancer and others. Chronic obstructive pulmonary disease: Chronic obstructive pulmonary disease (COPD) is lung disease which results from long term smoking and includes symptoms and effects of chronic bronchitis and emphysema. According to a research nearly 12 million people in United States of America suffer with this illness and another 12 million suffer with the disease but are unaware of its early symptoms and signs. And the rate of people suffering with COPD is increasing day by day that it has become the third major reason of death in the United States. It has also been noted that women suffer from COPD more acutely then men. Major reason behind suffering from COPD is smoking, almost 80-90% of COPD deaths results from smoking. There is no cure for COPD and its effects depends on how long and heavily the patient been smoking. Early symptoms and signs of the disease go unnoticed in early smoker, but the time it is diagnosed it has done its work. Early symptoms of the illness may include different noises like rattling and whistling in the chest, shortage of breath during some activities, heavy coughing along mucus (phlegm) discharge. With the time as the disease grows it make hard and impossible for one to breathe. It restricts one’s activities because of shortness of breath and results in grave health issues. Chronic stage of COPD cause patients to gasp for the breath (American Cancer Institute, 2014). Chronic Bronchitis Chronic bronchitis is another form of COPD, an illness which causes respiratory tracts to discharge heavy mucus, thus resulting in choking and shortness of breath and makes the patient to cough out all the mucus. Bronchitis is a common disease for smokers, so smokers must be ready to face the flaks of their unhealthy habit. Constant mucus discharge results in inflamed and swollen wind pipe and produces long lasting chronic cough. With the help of medication, symptoms can be cured but cough never go away and mucus inflammation can result in bad respiratory infections as well like pneumonia. There is no treatment for chronic bronchitis but stopping smoking can do little help and can control the inflammation and cough and with the time it may get better as well but if one doesn’t leave smoking then the illness keep on growing (American Cancer Institute, 2014). Emphysema Emphysema another form of COPD results from excessive smoking which gradually hampers one’s ability to breathe. There are tiny sacks in our lungs which provide surface area to oxygen in lungs to get mixed with the blood. But in emphysema these small sacks rupture and results in few large sacs which narrows the surface area and allow less oxygen to enter blood and sometime very less oxygen mix up with blood. With the passage of time disease get severe, very little oxygen reach up to blood and person had to do lot of efforts to breathe. It not only hampers one’s daily activities but make one gasp for breath even at rest. Symptoms of emphysema includes constant and heavy cough which never go away (Smoker’s cough), shortage of breath even when one is not working, dizziness, decrease in weight and general body fatigue. People suffering from emphysema may suffer from other health issues specifically related to lungs and can cause poor lung functioning, lung infections like pneumonia, shortage of breath to an extent that an individual has to rely on oxygen tube. There is no cure of treatment of this illness but the only possible solution is to quit smoking so the symptoms lessen down with the passage of time but if one doesn’t quit smoking it may lead to cancer and death as well (American Cancer Institute, 2014). Resources: Morris and Koyama, 1990 Joel Spitzer, 2001 American Cancer Institute, 2014 World Health Organization, 2011 Two research topics can be developed from this literature Smoking is one of the leading causes of death in United states; Smoking causes lung disorders even cancer as well. 5. It is very much evident from above mentioned researches and studies that smoking have an injurious and direct effect on one’s health specifically on lungs and may lead to cancer and death as well. It is very important to study the effects of smoking, smoking behaviors and its resulting health effects because smoking is one of the greatest causes behind lung cancers and deaths across the globe. This matter should be dealt seriously and immediate attention should be paid. 6. In the above mentioned research topic â€Å"Effects of smoking on lungs leading to cancer and death† smoking is the independent variable in this proposed topic of research as it bring changes but remain unaffected itself. Lungs, cancer and death are the three dependent variables as the amount of change and effect they will bear depends on the smoking. Smoking: Independent variable of the research, effects health, lungs, cause cancer and death; Lungs: dependent variable, effects by the independent variable smoking; Cancer: a major effect of smoking independent variable, is a dependent variable Death: a dependent variable, independent variable smoking leads to death. 7. â€Å"Effects of smoking on lungs causing cancer and death† 8. Where smoking is independent variable while effects on lungs, cancer and death are dependent variable. 9. Hypothesis: Smoking effects lungs and causes cancer and even lead toward death. Questions: 1. does smoking effects lungs functioning? 2. Does smoking cause cancer? 3. Does smoking lead to death? Statement: Effects of smoking on lungs, causing cancer and death. 10. Questions are the best choice for the detailed study and analysis of the subject matter. 11. Questions are best suitable for this research because smoking has different forms like mild, chronic and chain smoking which have different effects on lungs, causing cancer and leading toward death. Each questions will lead to detailed answer and explanation of how and why smoking effects lungs, causes cancer and death. If hypothesis is considered as objective then it might fail to highlight the different effects of smoking on lungs, smoking causing cancer and smoking leading to death individually, and it would rather warp up the discussion generally. So questions are the most suitable mode of inquiry for this research as each effect of smoking will be answer and laid out separately. 12. Conceptual definition: conceptual definition is the clear statement or description of something or how something works. It is used to define a term clearly, concisely and precisely. For example â€Å"Anxiety†, a conceptual definition of anxiety is unpleasant feeling effecting one’s working in few specific situations but sometimes motivate positive behaviors as well Operational Definition: Operational definition stand for defining something under different parameters, measurements and situations in order to validate it. Operational definitions can be very simple to very complex ones depending on the variables being used. An operational definition of anxiety can be that anxiety is just not a feeling but a physiological reaction of body resulting in increased heartbeat, muscle tension, sweating etc. 13. Conceptual definition. Smoking: an act of inhaling of tobacco or other related smoking products and exhale of smoke and other harmful gases. Lungs: A pair of organ found in almost all the living organism specifically in vertebrates, involved in inhalation of oxygen and exhalation of carbon dioxide. Lungs provide oxygen to whole body. Cancer: A harmful disease resulting from uncontrollable cell growth and have several different form depending on the area of body. Death: a state where an organism is not alive, breathing or sensing the environment. Death is also called expiry. 14. Operational definitions: Smoking: intake of tobacco and other harmful substances like nicotine etc. into lungs and outtake of harmful gases like carbon di oxide. Smoking causes social and physical illness Lungs: a pair of respiratory organs in humans involved in the oxygenation of the body. Lung are effected by the type of air inhaled, if smoke is inhaled it will have different effects on lungs then clean fresh air. Cancer: a specific form of cancer caused by poor functioning of lungs, inflammation of respiratory tracts, rupturing of air sacs, chronic cough and mucus discharge, difficulty or unable to breathe and physical deterioration of the lungs as well. Death: end of life resulting when lungs stops functioning and body is unable to get oxygen. 15. Level of measurement means classifying variables to develop a scale. Nominal scale will be used to find out the percentage and tendency of lung disorders, cancer and death resulting from smoking. Descriptive statistics will be used to summarize the data collected from the sample. 16. Data collection method depends on the type of variables and the relationship between them and is a systematic process to validate the hypothesis or answer the questions. There are three data collection methods, surveys, focus groups and interviews. It is the data collection which determine the authenticity of the research. Data collection instruments stands for the process data will be collected. Survey will be the instrument precisely data collection instrument to collect data from the population to find out the answers to questions. 17. A reliable and valid research instrument always give constant and accurate results whenever tested and studied. Reliability and validity of the questions will be done by a pilot study and by experts’ advice so to make sure questions are understandable and consistent. 18. Population of study is divided into two categories depending on the instrument of data collection. Individuals from rehabilitation centers will be the main population along the cancer patients in the hospitals as well. Apart from that interviews will be conducted with the physicians of patients suffering from lung cancer. 19. Simple random sampling technique will be used as it is the most convenient process to collect data. Researcher will visit the rehabilitation center and hospital and focus on the individuals with smoking related issues. 20. Research design refers to the overall planning and strategy to carry out research by linking and integrating all the components of research to find out solution to the research problem. This study is a descriptive study to find out relationship between variables by using research questions. Descriptive study attempts to define the link between various variables and will answer all the questions descriptively. 21. This study is both qualitative and quantitative. Research questions will be analyzed quantitatively to generate statistical data while interviews will be analyzed qualitatively. References: Morris. C, K. (1990).

Oedipus The King :: Oedipus Rex, Sophocles

The play begins with a request to Oedipus by the townspeople to rid Thebes of the plague, since he had so heroically solved the riddle of the Sphinx in the past. He sends Creon, his brother-in-law and uncle, to the oracles at Delphi. Creon returns with the cause for the plague; the murderer of the former King Laius was never punished for his crime. So Oedipus pledges himself to seek the killer and punish him as the gods wish.   Ã‚  Ã‚  Ã‚  Ã‚  Oedipus summons the people of Thebes and demands that the killer, or whoever had knowledge of the killer, reveal himself. He threatens them with the punishment of banishment. Some members of the group suggest consulting Tiresias, the blind prophet. When he comes, he proves to be useless with his intransigent silence. So Oedipus accuses Tiresias of being an accomplice to the murderer, forcing him to speak. Tiresias then charges Oedipus of the murder, which infuriates him, and also preludes to his “shameful intimacy.';   Ã‚  Ã‚  Ã‚  Ã‚  Oedipus then draws upon his solving of the riddle of the Sphinx to undermine the blind prophet, convinced that he, in alliance with Creon, was plotting against him. Creon’s modest rebuttal consisted only of a threat to himself- that if Oedipus’ claim against him were true, then let him not live out the rest of his days. Later, in a conversation with Oedipus, he justifies his denial of the charge that Oedipus had placed against him by illustrating the irrelevance of attempting to dethrone the king. When Jocasta enters, she sides with Creon and respects his oath to the gods. But later, when Oedipus says the claim against him is based on prophecy, she reasons with him since she does not believe in prophetic power. She explains how the prophecy of Laius’ son killing him never came true. Then Oedipus realizes that it was he that had slain Laius and that there was a chance Tiresias was right after all.   Ã‚  Ã‚  Ã‚  Ã‚  Oedipus pursues his search for his origin through several occasions. A Corinthian messenger is the first. He is the one that was given Oedipus with ankles pinned and in turn gave him to Polybus. The messenger plays an important role in revealing this as well as the fact that Polybus and Merope were not Oedipus’ real parents.

Emily Dickinsons Use of Humor and Irony Essay -- Emily Dickinson Poem

Emily Dickinson's Use of Humor and Irony While much of Emily Dickinson's poetry has been described as sad or morose, the poetess did use humor and irony in many of her poems. This essay will address the humor and/ or irony found in five of Dickinson's poems: "Faith" is a Fine Invention, I'm Nobody! Who are you?, Some keep the Sabbath Going to Church and Success Is Counted Sweetest. The attempt will be made to show how Dickinson used humor and / or irony for the dual purposes of comic relief and to stress an idea or conclusion about her life and environment expressed by the poetess in the respective poem. The most humorous or ironic are some of the shorter poems, such as the four lined stanzas of "Faith" is a Fine Invention and Success Is Counted Sweetest. In "Faith"..., Dickinson presents a witty and biting satirical look at Faith and its limitations. While it still amuses readers today, it must be mentioned that this short poem would have had a greater impact and seriousness to an audience from the period Dickinson lived in. Dickinson was raised in a strict Calvinist household and received most of her education in her youth at a boarding school that also followed the American Puritanical tradition she was raised in. In this short, witty piece Dickinson addresses two of the main obsessions of her generation: The pursuit of empirical knowledge through science, faith in an all-knowing, all-powerful Christian god and the debate on which was the more powerful belief. In this poem Dickinson uses humor to ease her position in the debate on to the reader. Dickinson uses her ability to write humourously and ironically (as seen in her suggestion of the use of microscopes) to present a firm, controversial opinion into w... ...ntuate the humor in the juxtaposition of the objects in order not to trivialize her own beliefs, but allows enough humor to enter the description to stamp the poem with the child-like free spiritedness found in ...Nobody.... Again in this poem, the poetess' desire for seclusion and unconventionality is expressed eloquently through a light-handed treatment of the subject matter. In conclusion, it can be stated the examples of Emily Dickinson's work discussed in this essay show the poetess to be highly skilled in the use of humor and irony. The use of these two tools in her poems is to stress a point or idea the poetess is trying to express, rather than being an end in themselves. These two tools allow her to present serious critiques of her society and the place she feels she has been allocated into by masking her concerns in a light-hearted, irreverent tone.

New England consisted their government around religion Essay

The New England and the Chesapeake regions were both from English origin. However, they had completely different societies. Each settlement had different intension of why they wanted to settle in the new world. New England and Chesapeake colonies had political, economic and social differences. The New England colonies consisted of puritans who wanted to purify the church because the Church in England was corrupt. They wanted a place where they could worship freely and work together to make a perfect society. New England consisted their government around religion. John Winthrop, A Model of Christian Charity quotes â€Å"God Almighty in his most holy and wise providence hath so disposed of the condition of mankind, in all times some must be rich, some poor,..† (Doc. A) This document shows their importance in god freedom and working together. The Chesapeake colonies wanted to settle in the new world because they wanted to find gold and riches. In Document C it show the comparison in men and women. There were many more men than women because their only goal was to find gold. In Document B, it shows that in the New England colonies many families were wanting to settle in the new world. For the Chesapeake colonies it was very hard for them because when they settled they did not plant any crops because they were to focused on finding gold so by the time winter came around they had no food which was called â€Å"The Starving Time† John smith in, history of Virginia quotes â€Å"Our ordinary was but meal and water so that this†¦ little relieved our wants, whereby with the extremity of the bitter cold frost†¦ more than half of us died.† (Doc F.) In the New England colonies they planted crops and one farm could feed a whole family

Effect on the Skeletal System of Young People Performing Contact

Activity is beneficial for people of all ages. People who are fit will, in general live longer and maintain a more active and fulfilling lifestyle. However there are some downsides to physical activity, in particular at high level. A large majority of ageing athletes suffer from long term injuries such as the poor state of someone’s knee. It is generally regarded that contact sports are beneficial to children. This is due to the fact that the majority of bone density material is developed when the person is young.This is beneficial to people because many bone diseases such as osteoporosis are connected to low bone density and inactivity as a young adult. On the flip-side when competing in high impact sport there is a very high chance of some sort of injury occurring along the way. For example if someone dislocates their shoulder playing rugby, it is more than likely that this will trouble them in the future. In addition to this when playing contact sports, the joints that are covered in articular cartilage can be worn away at a more rapid rate. Indeed, some injuries even lead to the cartilage being taken out altogether.This is a negative effect of contact sports on the skeletal system of young people as they may well end up suffering from osteoarthritis later in life. Osteoarthritis is thought to be related to cartilage being worn down to the point that the bone is no longer protected. High impact sport is generally considered to be a beneficial activity to people of all ages. Similar to contact sport, when competing in high impact sport the bone mass is built up. This is due to the fact that when someone runs solidly for half an hour, bones such as the tibia will suffer from tiny fragments breaking of the main bone.When this subsequently re-heals it will be stronger than it was before and allow for more exercise to be done on it. However, a high impact sport such as hockey, basketball or netball can be quite dangerous as it is thought that anterior cruc iate ligament injuries appear to be very common among sports that involve a lot of pivoting. Damage to this particular ligament can have a lasting affect on an athletes career and even put them out of action for good. The anterior cruciate ligament is so important because it prevents hyperextension in the knee.Women have even more problems with this ligament due to anatomical differences. This is a big disadvantage in young people competing in high impact sports as it could prevent them at a young age from taking part in anything ever again. In young people, especially teenager’s repetitive injuries often occur the at growth plates. Repetitive injuries occur when repeatedly over time the body doesn’t have a chance to repair, and the joints and surrounding tendons and muscles become irritated. The chance of repetitive stress injuries can be reduced by simple things, such as having a rest period where the body has time to recover.In addition to this using proper equipmen t also is a big factor, such as using proper running shoes to run in. If repetitive stress injuries go untreated then it is likely that the performer will have to stop competing in physical activity for a long period of time. Although serious, repetitive stress injuries can be avoided by using the correct precautions and are pretty much controlled by the performer as a pose to the outside environment. In summary of this it is clear that the different types of physical activity discussed above all have their positive sides and negative sides.However, in my opinion the positives of by far outweigh the negatives. Physical activity brings about so many other positives as well as just the physical aspects. Such as when participating in team sport a sense of unity, self confidence etc. These positives, for me, far outweigh the possibility of injury occurring. In addition to this if we always worried about things happening to us nothing would ever be done, we would just sit at home. Theref ore I think the rewards of physical activity far outweigh the negatives.

Nvq 2 Health and Social Essay

Personal centred approach is when carers take interest in what service users prefer and use this when providing care. Also, its thinking about the service users choices, right, protecting their privacy and dignity, supporting their independence and working in partnership with them and other colleagues to make the care better. 2. Person centre approach enables individuals with dementia to be involved in their own care and support because carers can talk to the resident and find out how they prefer things to be done, how they like to be spoken to and cared for so staff can give the best care in the way that suits them. Outcome 2 1.Information about personality and life history can be used to support an individual to live well with dementia because if they have a good written history it can help with communication, knowing what the person likes and dislikes if they are unable to tell you. Having a good life history can be used to support and live well because it helps people know more about someone, and look after them better meaning knowing how the like things. Outcome 3 1. All these things make up personal centred approach. Before giving someone care or help with something if we think about all these things and what the service user prefers we can provide the best possible care for them. Also, if we’re providing good care and the service user is happy then they start to feel comfortable and will tell us more about their choices and preferences so we’re able to provide our care at a even higher standard. link
