Educational circles Essay Lifelong education is a concept not to vague in today’s educational circles. It has been used in many different forms to promote a person’s pursuance to knowledge. It is claimed that life is education, practically speaking when you live you encounter deterrents or resistance in forms of challenges. It is normal for a person to face this situation, in here you will see that ones failure and challenges arise man’s normal tendency is to adapt and move on. Therefore learning and educating himself on the situation he/she has just experienced (Smith M. 1996). The issue that can be seen in pursuing further education is Man’s ability to absorb and effectively comprehending knowledge at a certain age. Man’s psyche changes as it progress deep into the application of his/her field or application. When the application stage of man kicks in he or she finds it difficult to learn new things because his/her paradigm is already stuck on its present state. That’s why preparation to a lifelong education is vital. It features a lot of difference between specializing. Specializing is done when man pursues and therefore encloses himself to a specific study. Not only that, he or she will be engrossed in its application, one reason for this is the field maybe his or her source of income. Examples are doctors, engineers, or architects who pursue to improve knowledge in their respective fields. The difference between lifelong learning and specialization is on it’s the width of its spectrum. A person pursuing a lifelong learning is more open he or she views mistakes as an opportunity of learning. A person pursuing specialization is not close minded but more coherent in their studies, and they usually have a rigid paradigm. The importance of differentiating lifelong learning and specialization is important. Creating standard studies on this topic will give students and educators a point of reference. This point of reference will assist our education system on integrating this to a learner’s life. Show them the advantages and disadvantages of pursuing one side to the other. Or even provide an evolvement study to at some proportion integrate the two different sides together. Reference: Smith M. (1996).

Psychological Aspects of Theravada and Mahayana Buddhism Essay Example for Free

Psychological Aspects of Theravada and Mahayana Buddhism Essay Though the most of the teachings followed by the different sects of Buddhism vary and conflict with each other, the general core values set by Buddha are still followed by all Buddhists. In regard to this we examine two Buddhism sects namely Mahayana and Theravada Buddhism. Whilst Theravada is psychologically oriented, Mahayana is idealistically oriented. The two sects have varying perceptions of the reality and the world besides the concept of being. There are many inherent differences between the two sects of Buddhism though the two seem to broadly agree on the original teachings of Buddha. Firstly, Theravada Buddhism denies the existence of any true being behind any given phenomenon and consequently avoids making metaphysical statements unlike Mahayana which teaches an Eternal Absolute included in many names. In this sense, Mahayana holds that all beings in all forms are identical with the absolute in their cores. Moreover, Mahayana sees Gautama as seeing through the projection of the absolute though it holds or possess a mortal frame of illusion which is frail. On the other hand, Theravada consider Gautama as a natural teacher or a superman at most. In the teachings of Theravada, liberation can only be achieved through an individual’s effort as opposed to the teaching of Mahayana which holds that liberation can be achieved through the help of outside assistance and deliverance through the power of others (Paul, 1999, 45). Moreover, Theravada Buddhism teaches it followers to set their ultimate goal to be the achievement of nirvana as opposed to the case of Mahayana which its ultimate goal is defined in following the ways of bodhisattva in leading all other human beings especially the sentient beings to liberation. In addition, Theravada Buddhism sees Hinayana as the final exit from the world while the same to Mahayana Buddhism is considered as achieving consciousness of an individual absolute nature and gaining mental aloofness state from all suffering. As seen in the teachings of Mahayana Buddhism, it attitudes are organized in such a way that an individual or a follower should endeavor to help the world and unselfish to it. On the contrary, Theravada attitudes are such that it followers should always endeavor to defeat the world through analysis strategies employed on its elements and through using knowledge and experience of an individual conduct. Mahayana Buddhism sometimes referred to as Northern Buddhism or the great wheel (vehicle) is mostly found in china, Vietnam, Japan, Korea and Nepal. It is usually followed by monks and lay. In essence, the Monks follow the rules set by Vinayas and which constitutes the prescriptions for monastic life in the Tipitaka also known to be Theravada sacred canon. However, they do this via the interpretation of Mahayana. In addition, the Monks also take vows to strive attain bodhisattva, with those who pursue esoteric practices of Tantric Buddhism taking Tantric initiations and vows (Michael, 2003, 56). In essence, Mahayana Buddhism is founded on speculations of metaphysical nature in respect to the nature of reality or what can be termed as enlightenment in addition to the core values set by Buddha. The general idea of Mahayana Buddhism is that when one achieves enlightenment, such a person returns to the world as a Bodhisattva to join other human beings. In this context, this branch of Buddhism emphasizes that the duty of a Buddhist who has achieved enlightenment is compassionately work in an effort to help end the sufferings of other Buddhists. In addition, Mahayana Buddhism holds the argument that through enlightenment, all creatures which can be considered as sentiment will finally achieve Buddhahood (Christopher, 1999, 23). Mahayana Buddhism is commonly divided into philosophical schools which are known to be influential not only to the Mahayana Buddhism but also to the Shankara and Advaita Vedanta as well. In this regard, the dialectic school also known as Madhyamika constitute one of the two schools of Mahayana. In essence, this school emphasizes negation of every possible phenomenological reality through logical reducto-ad-absurdum means in an effort to achieve Shunyata which can be seen as ineffable absolute or void and which is considered as the only reality. The concept of Shunyata was introduced in an effort to refute the delusions caused by separate enduring egos. Moreover, the concept was adopted to emphasize the ways in which everything in the universe is connected to each other. The second school is a consciousness doctrine also known as Vijnanavada. This school uses mediation process in an effort to prove that consciousness constitutes the ultimate reality. Unlike the other school, Vijnanavada has a number of occult and metaphysical conceptions including an emanationist which psychologically oriented but similar to Samkhya which is on the contrary cosmologically oriented. Mahayana Buddhism is centered on the noble Bodhisattva ideal which guides the enlightened Buddhists while dealing with the sentimental beings. In definition, a bodhisattva can be seen as a being who is in constant search of means of achieving or attaining Buddhahood in order to benefit sentiment beings. The conception of bodhisattva was developed from the idea of a Buddhist who differs with the ultimate goal of extinction also referred to as nirvana so that such a person can often make his or her way back to the world of suffering and help end the suffering of sentient beings (Michael, 2003, 59). In essence, the idea of bodhisattva is considered as demonstrating selfishness in the doctrine of Mahayana Buddhism largely because a bodhisattva having not reached nirvana, postpone enlightenment so as to help the sentient beings. On the other hand, Theravada Buddhism is seen as the oldest surviving school of Buddhist school and began first in India. It is also known as Hinayana and is relatively close to original Buddhism and conservative as compared to Mahayana Buddhism. Different from the teachings offered by Mahayana, Theravada emphasizes on the concept of Vibhajjavada or Pali which is literally used to mean the teaching of Analysis. According to this teaching, insight comes from the experience of the aspirant coupled by reasoning instead of by blind faith and critical investigation. Despite this teaching, the scriptures adopted by Theravada Buddhism emphasizes on the need to heed to the advice of the elders or the wise. In essence, heeding to the advice given by the elders and evaluation of one’s experience are considered to be the two vital tests on which the judgment of practices adopted by any given follower should be based. In Theravada Buddhism, the cause of human suffering and existence is identified as tanha or a craving which constitutes all the defilements inclusive of sensual desires, anger, ill will, jealousy, fear, hatred among others. In this context, the level of defilement can be coarse, subtle or medium. In essence, the phenomenon of defilement in Theravada Buddhism is seen as arising temporary, taking hold for a short time and then vanishing all together. In this respect, the doctrine of Theravada Buddhism believes that defilements are harmful not only to the person who commits them but also to others and that they are the force behind all the inhumanities committed by any given human being. Moreover, the followers of Theravada Buddhism holds the believe that defilements constitutes habits which are born out of ignorance afflicting the minds of the unenlightened human beings. Being under the influence of defilements, human beings are believed to cling to them by ignoring the established truth. On the other hand, these defilements are considered to be nothing but taints afflicting the mind of human beings consequently creating stress and suffering. Furthermore, the doctrine of Theravada Buddhism believes that the unenlightened human beings tends to cling to their bodies with the assumption that it is their self while on the contrary it present itself as an impermanent phenomenon which is formed on air, fire, water and earth. In this context, it is believed that the body will decompose and disperse after death. Moreover, it is believed that the mental defilements’ continuous and frequent manipulation and instigation of human mind prevents it from seeing the true nature of reality. These defilements according to Theravada Buddhism are further strengthened by unskillful behavior and that if a human being follow a noble eightfold path, he or she can weaken or overcome these defilements. The doctrine of Theravada Buddhism believe that those who are unenlightened experience the world through imperfect six senses inclusive of the ears, the eyes, nose, tongue, mind and tactile sense. They then goes on to use the mind which is by then clouded by much defilement in forming their interpretations, perceptions of reality and conclusions. In essence, the conclusion reached is based on the perceptions of these individuals in regard to the reality. On the other hand, the five physical senses are inactive to unenlightened person and consequently, the defilements are further strengthened unlike in the case of an enlightened person where the senses are wholly active thus suppressing any defilement. In order for any human being to overcome the stress and suffering caused by these defilements one must strive to overcome the defilements first. The defilements in this context are believed to be initially restrained through mindfulness in regard to preventing them from taking over the bodily and mind action. To uproot them therefore, one need to undertake internal investigation and to analyze and at the same time understand the experience and the true nature of such defilements through the use of jhana. The process of uprooting the defilements need to be performed on each kind of defilement if optimal results are to be achieved. Consequently, the mediator will realize four noble truths as believed by the Theravada doctrine which will help him in achieving enlightenment and overcome the defilements completely (Prebish, 1994, 67). In essence, the doctrine of Theravada Buddhism consider enlightenment and Nibbana as their ultimate goals. In this sense, Nibbana is thought of as the perfect bliss through which a person is freed from the cycle of birth, illness, aging and death. The doctrine believe that each and every person should be held personally responsible for their own liberation and self-awakening. In this context, every individual is the one responsible for the consequences of his or her actions as well as those specific actions. As such, by simply believing and striving to learn the truth as provided for by the original Buddhism, an individual cannot fully be awakened but rather he or she must strive to know and conceptualize such reality through direct experience. In this regard, the individual has to follow the teachings of Buddha in respect to the noble eightfold path in an effort to individually discover the truth. According to the doctrine of Theravada, gods, Buddhas, or even deities are not capable of offering awakening to any human being and as such are incapable of lifting from freeing them from the samsara cycle of birth, ageing and death. According to the beliefs held by followers of Theravada Buddhism, Buddhas are only teachers while the gods and deities are subject to anger and other forms of defilements (Robinson, 2005, 46). Theologically, Theravada Buddhism is founded on the four noble truths which are also referred to as the four sublime truths. In essence this can be disseminated as defining the problem, the cause of the problem, the solution to such a problem and the methods and ways that must be followed to attain that solution. Firstly, Theravada Doctrine takes suffering or Dukkha as one of the four noble truths. In this regard, we can have inherent suffering which includes all forms of suffering undergone by an individual as a result of worldly things . On the other extreme, we can have suffering that results from change and finally suffering that is caused by one’s failure of recognizing that he or she is an aggregate definite with an identity that is unsusceptible to change. Secondly, we have the cause of the suffering referred to as Dukkha Samudaya and which can be defined as a craving that leads an individual to worldly bondage and attachment thus causing suffering for such an individual. In this regard, Kama Tanha is the act of craving for any given pleasurable object as a result of the body senses. On the other hand, Bhava Tanha is when an individual crave to be attached to a particular ongoing process such as the longing for existence. Still, Vibhava Tanha is when an individual crave to be detached from any given ongoing process such as the longing for self annihilation. The third truth called Dukkha Nirodha can be seen as a cessation for suffering. According to this truth, it is impossible for one to adjust the entire world in order to fit in his or her taste in an effort to free from suffering. On the other hand, one must adjust his or her mind through detachment process so that any occurring change will have no effect on the peace of mind of such an individual. In other words, the elimination of the craving or the cause will help in eliminating the result. The final truth is a pathway to freedom from suffering and is known as Dukkha Nirodha Gamini Patipata. It is commonly known as the noble eightfold pathway towards Nibbana or freedom. It constitutes the right intention, speech, actions livelihood among other right things that an individual needs to do to free from suffering. According to the doctrine of Theravada Buddhism, all conditioned phenomena including physical qualities, knowledge, theories adopted and the physical characteristics are subject to change with time. This is referred to as Anicca which can also be taken to mean impermanence. Moreover, the teachings of Theravada holds that suffering or Dukkha is caused by craving in the sense that whatever is craved for is subjected to change, transition and perishing. In this regard, the impermanence of the craving object causes sorrow and disappointment in the long run. Since individuals are the one involved in labeling the objects to be liked and those to be disliked on one hand and the comforts and discomforts in the world on the other hand, they are the ones who create suffering in the first place. In this context, if an individual succeeds in overcoming the tendency to label thing in the world, he or she will be free from suffering (Prebish, 1994, 68). Still, Theravada Buddhism uses the concept of anatta in referring to the lack of unchanging and fixed identity. In this regard no specific phenomenon constitutes any individuals’ essential and permanent self. In essence, any human being is composed of five aggregate elements. First, there is the rupa which includes the feelings and other forms of sensations also known as vedana, sanna which includes all the perceptions held by an individual, sankhara which is the mental formations arising from the perceptions and vinnana or the consciousness. All of this cannot be identified as ones’ self but rather together forms the core of an individual. The realization of anatta, dukkha and anica enables one to achieve freedom and to reach nibbana, a state in which one is complete and ultimately free. In regard to meditation, Theravada Buddhism sees it as a way of positively reinforcing the mind of the individual in question. In this respect, mediation is categorized into two. Samatha which in literal terms mean making something skillful includes the acts of achieving visualizing or tranquilizing reality through meditation. Vipassana can be defined as insight or abstract understanding through meditation. In essence, samatha helps one to skillfully concentrate the mind while vipassana helps in seeing through the veil of ignorance (Paul, 1999, 47). In conclusion, while it is easy to disseminate the psychological orientation and aspects of Theravada Buddhism, it is hard to identify the psychological perspectives of Mahayana Buddhism. This is because as stated earlier Mahayana is idealism as opposed to Theravada Buddhism which is psychologically oriented. The teachings of Mahayana Buddhism are those of metaphysically assisting other human beings to achieve enlightenment though the one helping need not have fully achieved it himself. In other words, it teaches it followers to be unselfish to the others and to the world as a whole. It teaches its followers to strive to attain enlightenment and to help others who have not attained it do so. On the other hand, Theravada teaches its followers to strive to overcome the world through individual efforts other than relying on external assistance. In essence, Theravada Buddhism encourages its followers to find effective means of overcoming their defilements and thus to free themselves from sufferings. It holds that the suffering undergone by any individual starts with that individual himself and thus he or she is the only one who can liberate himself from such suffering.

A Web-Based application for Patients and Caregivers

A Web-Based application for Patients and Caregivers 1. The Reminiscence system Based on our findings in the pilot study (Sarne-Fleischmann and Tractinsky, 2008), a new Flash web-based application was developed to enable independent use and administration for both patients and caregivers by including two main components in the structure. The front-end component supports the patient’s interaction with the system during the therapeutic sessions. The back-end component facilitates the addition, update, and management of content. This component was designed for the use of caregivers and family. The application was developed by an experienced subcontractor according to a detailed design and the specifications provided. Great emphasis was placed on the system’s design and on simplicity of use, given the specific characteristics and limitations of the target users. Features included a very simple interface (offering the user a limited number of options in order to avoid cognitive overload); minimizing visual distractions on the display; avoiding the use of animations or competing stimuli at any given time; using subtle graphics through calming color schemes; and using a touch screen for all required interactions to support the most natural interaction style. The new systems hierarchy included only three levels to support simple and intuitive flow: Login – Entering the system by identifying the patient. Select Album – Selecting the required album from up to six albums presented. Album View – Watching the media files associated with the selected album. The navigation between the three levels is done hierarchically and is bi-directional. The reminiscence system has two different interfaces: Hebrew and English. The two interfaces are separated (each is accessible via a different link) so there is no option of switching to a different language while interacting with the system. A usability evaluation was conducted prior to the commencement of the evaluation study, in order to evaluate the appropriateness of the new system for the target audience (Sarne-Fleischmann, Tractinsky, Dwolatzky and Rief, 2011). The usability evaluation included three Alzheimers patients, who were asked to use the system in separate sessions, while being observed and interviewed regarding their mental model of interacting with the system. Based on the usability evaluations results, several modifications were made to further improve the system. 2. Methods 2.1 Patient sample The participants of this study were older subjects with cognitive impairment or dementia who resided in the community and regularly attended an adult daycare center at least twice a week. The inclusion and exclusion criteria are described in Table 1. Table 1: Inclusion and exclusion criteria Inclusion criteria Exclusion criteria (1) Age – above sixty years old (5) Psychiatric disease (2) Cognitive impairment – mild cognitive impairment (MCI) or dementia (MMSE score of 14-26) not associated with a known medical condition (such as stroke, vitamin deficiencies, impaired thyroid function, among others) (6) Significant visual or auditory impairments or any other impairment which may prevent the participant from using either of the two computerized interventions (3) English / Hebrew / Russian speakers (7) Inability to understand the questions presented in the Savion software program, or inability to communicate coherently as required for the performance of reminiscence therapy. (4) Have close relatives who could act as informants Due to the diverse symptoms of MCI and dementia, and in order to maintain a certain level of homogeneity, the age criterion (1) was determined in order to exclude cases of early onset dementia. In order to encourage the inclusion of subjects with an organic etiology for their cognitive impairment, participants with psychiatric disease (5) were excluded from the study. The language criterion (3) was based on the availability of these interfaces in the two computer systems. Due to the requirements of the screening tools, crucial information regarding the functional capabilities of the participants were to be obtained from a family informant (4). Moreover, the periodic evaluations included the impressions of family members who serve as the participants main caregivers. Each competent participant, as confirmed by an independent geriatrician, was asked to provide written informed consent prior to participation in the study. For those patients who were not competent, the legal guardian was required to provide informed consent. Subjects without a legal guardian who were determined not to be competent were not enrolled in the study. After providing informed consent, the participants medical files were reviewed in order to ensure that they conform with inclusion and exclusion criteria, and that their cognitive impairment was not the result of an associated medical condition (such as stroke, vitamin deficiencies, impaired thyroid function, among others). In addition, the participants underwent a preliminary assessment in order to determine the stage of their illness. The assessment included cognitive and functional evaluations using the following instruments: Mini-Mental State Examination for cognitive screening (Folstein et al., 1975). Clock Drawing test (Freedman et al., 1994) and CogSym questionnaire for cognitive screening (Memory Clinic, Mental Health Center, Beersheva). The latter is a numerical scale based on 10 questions used for elucidating cognitive symptoms, and is completed both by subjects and by informants. Lawton and Brody’s Instrumental Activities of Daily Living (IADL) for assessing functional capabilities (Lawton et al., 1969). This questionnaire is directed at the participants informant. Clinical Dementia Rating (CDR) scale as a global measure rating the severity of dementia (Morris, 1993). This questionnaire includes two parts: the first is directed at the informant and the second at the participant, comparing the latters response to that of the informant. Short version (15 questions) of the Geriatric Depression Scale (GDS) as a screening instrument for depression (Yesavage et al., 1983). All questionnaires directed to informants were administered by face-to-face or telephone interviews with first-degree relatives of the participants. All other scales were administered by face-to-face interviews with the participants during morning hours at the adult daycare centers. At the end of the screening process, the results of all evaluations were reviewed by a physician specializing in the treatment of cognitive syndromes, and the cognitive diagnosis was determined to be either MCI or dementia based on accepted criteria. 2.2 Design At the completion of screening, subjects were assigned randomly to one of three groups: Personal reminiscence therapy intervention (using the computerized reminiscence system with personal contents for each participant). Cognitive training intervention (using the Savion computerized cognitive training system). Control group which continued usual activities in the adult daycare center. The usual activities of all participants at the daycare centers and at their homes were not controlled. The purpose of randomization was to assure as much as possible that baseline characteristics of the participants of the three groups were similar. Randomization was stratified according to the daycare center, and to the severity of cognitive impairment (with CDR scores of 0.5 and 1 representing a milder degree of cognitive impairment, and CDR scores of 2 and 3 representing more severe impairment), see Figure 5. Figure 5. Randomization of participants in each day care center 2.3 Procedure Both those participants receiving reminiscence therapy as well as those using the cognitive training program participated in two sessions a week, each of 30-minutes duration, over a period of three months. The treatments were conducted in a quiet room at the adult daycare centers in the morning hours, and supervised by a trained mediator. At the end of each session, the mediator provided a short description of the interaction, relating to the course of the session and to special occurrences. 2.4 Measurements The following describes the measurements that were employed in the study. All assessments were performed at baseline (T0), at one month (T1) and at 3 months (T3). Responses from subjects relatives were obtained by face-to-face or telephone interviews. The name of the subjects relatives was provided by the staff of the adult day-care centers. 2.4.1 Cognitive function assessment In order to evaluate the efficacy of each of the interventions as compared to controls with regard to cognitive function, the subjects’ cognitive function was measured by the Mindstreams computerized assessment battery (Dwolatzky et al., 2003; Dwolatzky et al., 2010). The Moderate-Severe Impairment Battery was administered. This tool takes about 20 minutes to administer and tests the following cognitive domains: Orientation to time and place Language skills Memory Nonverbal memory Delayed nonverbal memory Executive function Similarities and judgment Reality testing Go-NoGo basic test Spatial orientation At the end of the test, data is uploaded to a server, scores are provided for all of the individual test components, and in addition a global score index is calculated for the test. A summary score for each domain (including the global score) reflects the level of accuracy, ranging between 0-100 (with 100 being the highest level of accuracy). 2.4.2 Patients’ psychological/ behavioral well-being Behavioral outcomes were assessed using the NPI Neuropsychiatric Inventory (Cummings et al., 1994), which was completed by the subjects first-degree relative. This tool includes 12 areas, each relating to the presence of a particular behavior, its frequency, severity and the level of caregiver distress. A total score is calculated according to the frequency and severity, and ranges between 0-144 (a higher score reflecting a higher level of symptomatology). Psychological well-being was assessed using the QoL-AD instrument (Logsdon et al., 1999), and a general question from the Will to Live questionnaire was administered (Carmel, 2007). The QoL-AD instrument obtains responses regarding the subjects quality of life both from the subject and the relative, and includes 13 items rated on a four-point scale. Total score of the instrument ranges between 13-52 (a higher score reflecting better quality of life). The Will to Live questionnaire was rated by the subject, and ranges between 0-5 ( a higher score reflecting a greater will to live). The Will to Live was measured by the question: If you could describe your will-to-live on a scale from 0-5, would you say that it is: 5=very strong, 4=strong, 3=intermediate, 2=weak, 1=very weak, and 0=no will to live?. The Will to Live is associated with the psychosocial indicators of well being rather than with the respondents health status (Carmel, 2001). 2.4.3 Caregiver burden For the assessment of caregiver burden and psychological morbidity, the short version of the Zarit Caregiver Burden Interview (Bedard et al., 2001) was used. This questionnaire was administered to the subjects first-degree relatives, and ranges between 0-48 (a higher score reflecting a higher level of burden).

Sir Wilfrid Laurier :: essays research papers

Sir Wilfrid Laurier The first French Canadian to become prime minister of Canada was Wilfrid Laurier. Although French was his native tongue, he became a master of the English language. This and his picturesque personality made him popular throughout Canada, and he led the young country in a 15-year period of great development. Wilfrid Laurier was born in St-Lin, Quebec, and studied law at McGill University. After three years in the Quebec legislature, he was elected to the Canadian House of Commons in 1874. There he rose rapidly to leadership. Although he was a French Canadian and a Roman Catholic, he was chosen leader of the Liberal party in 1887. Nine years later he became prime minister. He was knighted in 1897. "Build up Canada" were the watchwords of Laurier's government. Laurier was loyal to Great Britain, sent Canadian volunteers to help in the Boer War, established a tariff favorable to British goods, and worked to strengthen the ties between the two countries. But he saw the British Empire as a worldwide alliance of free and equal nations, and he opposed every attempt to limit Canada's freedom. Laurier's liberal immigration policy brought hundreds of thousands of settlers to the western provinces. He reduced postal rates, promoted the building of railroads needed for national expansion, and appointed a commission to regulate railroad rates. After 15 years in office his government was defeated, presumably on the issue of reciprocal trade with the United States. Laurier believed, however, that his political defeat was caused primarily by opponents in Ontario who considered him too partial to Roman Catholic interests in Quebec. Prior to World War I, Laurier tried forcefully to support the formation of a Canadian navy. His own Liberal party defeated this measure, however, and Canada entered the war without a fleet of its own. During the early years of World War I, Laurier supported the war policy of Sir Robert Borden's Conservative government. In 1917 he refused to join a coalition government that was formed to uphold conscription. Laurier felt that he could not back a measure so unpopular in the province of Quebec. Wilfrid Laurier's regime lasted 15 years. It was one of renewed growth and prosperity. The Manitoba School Question was promptly hushed up by new legislation enacted by the province in accordance with a compromise worked out with Ottawa. To his Cabinet Laurier drew some of the most capable leaders from every part of Canada. Business throughout the world was on an upswing, and the Laurier government was determined to get in on the action. The demand for Canadian wheat abroad encouraged immigration, and immigration in turn

The Latino Culture in America Essay -- Cultural Identity Essays

The Latino Culture in America Latinos have struggled to discover their place inside of a white America for too many years. Past stereotypes and across racism they have fought to belong. Still America is unwilling to open her arms to them. Instead she demands assimilation. With her pot full of stew she asks, "What flavor will you add to this brew?" Some question, some rebel, and others climb in. I argue that it is not the Latino who willingly agreed to partake in this stew. It is America who forced her ideals upon them through mass media and stale history. However her effort has failed, for they have refused to melt. The struggle to find a place inside an un-welcoming America has forced the Latino to recreate one. The Latino feels out of place, torn from the womb inside of America's reality because she would rather use it than know it (Paz 226-227).

War of 1812 :: essays research papers

List and discuss the events leading up to the War of 1812 and the impact it had on American and Great Britain relations, and the American economy. During Jefferson’s second term in office, fighting between Great Britain and France was posed as a threat to American shipping. Napoleon made the decision to exclude British goods from Europe. As a result, Great Britain decided to blockade Europe and prevent ships from entering or leaving the country. A year later, Britain confiscated American cargoes and seized more than a thousand American ships. France had seized about five hundred American ships as well. America’s anger began to focus mainly on the British, even though France was also involved. This was because of the British policy of impressments. The British decided to capture American sailors, or draft them into the British navy. Also, in 1807, the commander of a British warship insisted on boarding and searching the United States naval frigate Chesapeake. When a United States captain refused to allow him onboard, the British killed three Americans and wounded eighteen. As a result, Jefferson convinced Congress to declare an embargo and ban exporting products to other countries. The Embargo Act of 1807 was eventually lifted in 1809 because it stifled American business. A group of young congressmen, known as the war hawks, were angered by the presence of Native Americans in the Indiana territory. Trobule began when General William Henry Harrison persuaded several Native American chiefs to sign away three million acres of tribal land to the United States government. A confederacy of Native Americans began to organize a fight for their homeland against intruding white settlers. This was lead by Shawnee Chief Tecumseh. Tecumseh’s brother lead the Shawnee in an attack on Harrison, but was defeated. When the war hawks found out that the confederacy was using arms from British Canada, they again called for war. James Madison, another Virginia Republican, declared war against Britain in 1812. He believed that Britain was trying to strangle American trade and weaken the American economy.

Is Decoherence a Solution for the Measurement Problem

Abstract—Decoherence is considered as one of the important topics in quantum computing research area. Some researchers stated that decoherence solved the measurement problem and on the other hand many researchers stated the opposite. In this paper we will prove whether decoherence is a solution or not through an exhaustive survey of the different ideas, methodologies, and experiments. Index Terms—Quantum computing, decoherence, measurement problem INTRODUCTION Decoherence is considered as one of the important research areas since 1980s.Quantum decoherence is the Loss of coherence or ordering of the phase angles between the components of a system in quantum computing superposition and the consequence of this is classical or probabilistically additive behavior†¦ (Zurek Today 10 (1991)) Wave function collapse is the reduction of the physical possibilities into a single possibility as seen by observer can appear in quantum decoherence also it justifies the framework an d can predict using classical physics as an acceptable approximation†¦ Namiki and Pascazio 1991). However, decoherence is a mechanism that emerges out quantum stating point also it determines the location of the quantum classical boundary moreover decoherence appear when the quantum system interacts with its environment in a thermodynamically irreversible way and that lead to prevent different factors in the quantum superposition of the system and environments wave function from interfering with each other†¦ Zurek Today 10 (1991)) Decoherence can be viewed in different ways such as flowing information from the system to the environment lead to lose information this is known as heat bath since each system is losing some of its energetic state because of its surroundings environments†¦ (Kumar, Kiranagi et al. 012) There is also another view of decoherence that is called isolation; which is the combination of the system and the environment which known as non-unitary ther efore the dynamics of the system alone are irreversible also as a result of combination of system and environment the entanglements are generated between them and that will lead to sharing quantum information without transferring these information to the surroundings†¦ (Lidar and Whaley 2003) Describing how the wave function collaps occurs in quantum mechanics called measurement problem. The disability of observing the process directly lead to different nterpretations regard quantum mechanics, also it rises too many qustions that each interpretation must answer. However there are some researches provides aprove that the decoherence solved the measurment problem and some other researchers prove the opposite thus in this paper we will make a comparasion between these two different point of views†¦ (Kumar, Kiranagi et al. 2012) PROBLEM IDENTIFICATION Decoherence is a real challenge that prevents implementing quantum computers; because the machines rely on undisturbed evolutio n of quantum coherences†¦ (Chen, Ang et al. 003), (Flitney and Abbott 2004) Decoherence provides an explanations for the appearance of the wave function collapse it does not generate actual wave function collapse and that is the nature of quantum systems it leaks into the environment and that done by decomposing the component of the wave function from the coherent system and then applying phases to the environment†¦(Flitney and Abbott 2004) P. W Anderson claimed that decoherence has solved the Quantum measurement problem while S. L Adler prove the opposite†¦. Adler 2002) In this paper, we will conduct a comprehensive survey of the different views and experiments to come up with a solution for the relationship between decoherence and measurement problem. Decoherence is the Solution Zurek (1991), Tegmark and Wheeler (2001), and Anderson (2001) stated that decoherence has solved the quantum measurement problem by eliminating the necessity for Von Neumann’s wave fu nction collapse postulate. Osvaldo Pessoa Jr. wrote an article titled â€Å"Can the Decoherence Approach Help to Solve the Measurement Problem? He concluded that decoherence could help to solve measurement problem in open systems. From that point, he wanted to count on the open systems to solve the measurement problem of individual systems. He also mentioned that decoherence helps to get an approximate solution for the statistical version of the measurement problem. Wallace (2011) mentioned that decoherence explains why the measurement problem is a philosophical rather than a practical problem and stated that decoherence could solve the measurement problem.He claimed that the quantum state continues to describe the physical state of the world. So, decoherence finds its natural role in the measurement problem as the process which explains why quantum mechanics can be fundamentally deterministic and non-classical, but emergently classical. It does not dull the aspect of Everett's pro posal, which states that all are equally part of the underlying quantum reality. Decoherence is Not the SolutionThe decoherence initiative was to explain the transformation from large to conventional by evaluating the relationships of a program with a determining program or with the environment. It is realistic to think about a large specialized substance or program of pollutants as a divided program boating in unfilled space. Dynamical Failing Styles Somehow do not like the idea of failure due to professionals trying to rig the pattern function improvement so to advantage loss of the situation vector in a well described way.One way is to say that the pattern function, or at least an element of it, consistently gets â€Å"hit† in such a way as to cause localization in the position base. Another way is to add a not unitary term into Schrodinger’s program. There are suggestions stated that we can infer using mind ability to get the collapse of the wave function Tohmas Br euer at 1996 try to investigate these suggestions and apply it to recent results of quantum machines regard restrictions on measurement from inside.Tohmas Breuer count on these restrictions to come up with a phenomena of subjective decoherence therefore he split his article into parts. The first part is â€Å"measurement from inside† and he makes a presentation to illustrate why it is impossible for an observer to make a distinction between all states in a system in which an observer is contained and that consider as restriction on the measurability from inside, he conclude that bigger system O need more parameters to fix its state.However, this will lead to situations that big O can be determined of each physically possible state by the state of a subsystem A together with some constraint. Second part is â€Å"EPR-Correlations† and he focus on situation which stronger results hold when we take into account particular features of quantum mechanical situations for examp le if we have two systems A and some environment R then the union of two system A ? R equal to Big O. also if both systems A and R have Hilbert spaces HA and HR as state spaces then EPR correlations can be obtained in the vector states HA HR .Therefore he conclude that A con not make a distinction between states of O which is make difference only in the EPR correlations between A and R. however observers can only be able to make a measurement of EPR correlations between A and R in A ? R†¦(Breuer 1996) David Wallace wrote his article to achieve two goals the first one is to present an account of how quantum measurements are dealing with in modern physics in other word quantum measurements does not involve a collapse of the wave functions also to present the measurement problem from that account perspective of view.The second part is concentrate on clarifying the role of decoherence plays in modern measurement theory and what affects it has on the different strategies that have been proposed to solve measurement problem. Wallace concluded that it seems not possible to have a complete understating of the microscopic predictions quantum mechanisms without interpreting the state in a probabilistic way and that because of interference since quantum states cannot be thought of as probability distributions in physical states of airs.Therefore it is allowable to try to resolve the incoherence by two ways, the first one by philosophical methods which means trying hard to think about how to make a full understanding quantum states so as to come out with a non-incoherent way, also the second way done by making modifications on the physics which means trying to make a replacement of the quantum mechanics by using some new theory which does not prima facie lead to the conceptual incoherence.Finally, Wallace state that the natural role of decoherence can be found in the measurement problem as the process which provides an explanations regard why quantum mechanics, inte rpreted can be basically not classical and deterministic, but critically classical†¦(Wallace 2011) Dan Stahlke based on application he made state that the most important point of decoherence theory is that it provides understanding about the process of wave collapse. Some systems need to be built in way that it stays in coherent superposition.However, tendency of system that been in superposition can be immediately calculated. Also he stated that decoherence does not give the ultimate solution in the measurement problem but it bring some light to the matter†¦(Stahlke 1999) Maximilian Schlosshauer makes a distinctive discussion regard the role of decoherence in the foundation of quantum mechanics, and focusing of the effectiveness of decoherence regard the measurement problem. He concludes that within a standard interpretation of quantum mechanics that decoherence cannot solve the problem of definite outcomes in quantum measurement.Therefore he mention the effectiveness of environment super selection of quasiclassical pointer states along with the local superposition of interference terms can be put to large use in physical motivation, assumptions and rules regard alternative interpretation approaches that can change the strict orthodox eigenvalue-eigenstate link or make modification on the unitary dynamics to account for the awareness of definite outcomes†¦(Schlosshauer 2005) Elise M.Crull mention in his article that it has been claimed that decoherence has solved the measurement problem. In other hand, some researchers stated that it does not solve the measurement problem. However, the Crull target is â€Å"Which measurement problem? †, thus he argue three questions depending on Max Schlosshauer which has neat catalog on the different problems which called â€Å"the measurement problem†Ã¢â‚¬ ¦(Schlosshauer 2008; Crull 2011) Harvey Brown stated that there are many attempts to proof the insolubility of the measurement problem in non -quantum mechanics.We can use these attempts for quantum mechanics. These proofs tend to establish that if mechanical interaction between object system A and measuring instrument B is described through a suitable defined unitary operator on the â€Å"Hilbert† tensor product space, so the final state of the A + B together cannot be described by a density operator of a specific kind in that space.Therefore this leads us to a resolution in terms of weighted projections which be useful to interpreted as mixture of pure A + B states, which are eigenstates corresponding to the â€Å"pointer position† that observable connected with the instrument†¦(Brown 1986) Ford, Lewis and Connell count on a book â€Å"Decoherence and the Appearance of a Classical World in Quantum Theory† †¦(Giulini, Joos et al. 1996) which state that ‘‘irreversible coupling to the environment seems to have become widely accepted ~and even quite popular!During the last decade, not least through the various contributions by Woljciech Zurek and his collaborators. ’’ And he conclude that general and simple formulation of quantum measurement gives a good method regard discussing quantum stochastic systems†¦(Ford and Lewis 1986) . Also authors stated that decoherence appear at high temperature with or without dissipation and the time for both cases are the same furthermore at zero temperature, decoherence occurs only in the presence of dissipation†¦(Ford, Lewis et al. 001) In 1980s and 1990s techniques are established to cool single ions captured through a trap and to control their state by using laser light and the single ion can be observed using photons with minimal interaction with the environment. Photons can observed without being destroyed during interaction together with atoms in designed experiment. That leads to make a study regard pioneers that make a test for basis of quantum mechanics also the transition between microscopic and microscopic world.The most important stage in controlling the quantum state regard ion is cooling it to the lowest energy of the trap using a common technique called sideband cooling†¦(F. Diedrich, Bergqvist et al. 1989) this technique consists of exiting the ion, increasing inside energy also decreasing the vibration energy†¦(SCIENCES 2012) Bas Hensen starting his discussion by defining the measurement problem and he stated that measuemet problem begin naturally from quantum theory’s success through describing the realm regard microscopic particles also permitting them to have definite values for quantities like momentum and position.Then he split the problem into several parts. The first two parts are â€Å"the problem of outcomes: Why does one perceive a single outcome among the many possible ones in equation? †, â€Å"The problem of the collapse: What kind of process causes the state of the system to ‘collapse’ to the outcome one percei ved (in the sense that a repeated measurement yields the same answer)? † in these two part he found that in quantum the world must be divided into a wave quantum system and the rest stays in some classical system.Also in accuracy point of view the division is made one way or another in a particular application. The third part is â€Å"The problem of interference: Why do we not observe quantum interference effects on macroscopic scales? † in this part author stated that the best way to illustrate this problem by using the double slit experiment. The experiment shows that the physical setup suggests that grouping the probability distribution gained with either one of the slit opened should occur in the probability distribution regard the two slits opened.For this situation of electrons as particles the probability distribution regard course differs, but regard a similar setup using macroscopic particles it doesn’t†¦(Hensen 2010 ) Dieks reviewed several proposa ls that solved the quantum mechanical measurement problem by taking into account that in measurement interactions there are many unobserved degrees of freedom. He found out that such â€Å"solutions† are unsatisfactory as they stand, and must be supplemented by a new empirical interpretation of the formal state description of quantum mechanics (Dieks 1989).Zurek mentioned in † Decoherence, Einselection, and the Quantum Origins of the Classical† that decoherence is caused by the interaction in which the environment in effect monitors certain observables of the system, destroying coherence between the pointer states corresponding to their eigenvalues. Then, he mentioned that when the measured quantum system is microscopic and isolated, this restriction on the predictive utility of its correlations with the macroscopic apparatus results in the effective â€Å"collapse of the wave packet†; which implicitly states that decoherence did not solve the measurement p roblem (Zurek 2003).Elby scrutinized the claim that the measurement problem is solved by decoherence, by examining how modal and relative-state interpretations can use decoherence. He mentioned also that although decoherence cannot rescue these interpretations from general metaphysical difficulties, decoherence may help these interpretations to pick out a preferred basis (Elby 1994). Janssen mentioned that the alleged relevance of decoherence for a solution of the â€Å"measurement problem† is subjected to a detailed philosophical analysis.He reconstructed a non-standard decoherence argument that aimed to uncover some hidden assumptions underlying the approach. He concluded that decoherence cannot address the â€Å"preferred-basis problem† without adding new interpretational axioms to the standard formalism (Janssen 2008). Busch et al (1996) explained decoherence using the many-worlds interpretation and stated the decoherence cannot solve the measurement problem. Legge tt (2005) concentrated on the paradox of Schrodinger's cat or the quantum measurement paradox to prove that dechorence is not a practical solution.Other researchers and scientists including Gamibini and Pullin (2007), Zurek (2002), Joos and Zeh (1985), Bell (1990), Albert (1992), Bub(1997), Barrett (1999), Joos (1999), and Adler (2002) stated that decoherence did not solve the measurement problem. Conclusion There is a serious and unresolved quantum measurement problem. Some, like Ghirardi, Rimini, and Weber (1986), try to solve it by modifying quantum mechanics. If successful, such attempts would result in a theory, distinct from but closely related to quantum mechanics, that is no longer subject to a measurement problem. That problem may be unsolvable (Healey 1998).
