Memorable moment Essay Example | Topics and Well Written Essays - 250 words
Memorable moment - Essay Example This moment also triggered the main efforts by the U.S government to combat terrorism. 2750 individuals lost their lives in New York City while 184 and 40 persons were killed at the Pentagon and Pennsylvania respectively. Subsequent reports indicated that all the involved terrorists were killed. I came to learn this through television images on my way home from my classes as I walked past a coffee shop. One would ask, to what extent was its representation in images and wording significant to this memorable moment? All television stations switched from the programs they were airing at that moment and moved to air this happening. Some of the women watching this close to me broke into tears most probably they had loved ones in those hit areas, or they were pushed by anger and patriotism. This imagery of that moment haunts me to date making it a memorable moment. The images of people being saved from the ramble, the smoke, the sirens and all other factors defining this day can and will never be erased from my

Case Study Example Coke could have researched how to spend their resources in order to employ it more effectually. It is evident that Pepsi was spending little and gaining the market share, the big question is where was coke then? Research is an important step in advertising since money was wasted yet there various other uses within the organization that money could have helped. For coca-cola to improve the stated issues above the corporate could do number of things. The change of coke flavor done by the company was quick and by doing more study, the issue may have not been the taste that was suppressing their sales. Companies should look into every latent change to a product, and establish the best fit with diverse study surveys groups,à discussions, etc. clients are very instrumental in decision-making since they are the companyââ¬â¢s business. Press and broadcast media are most of the times expresses and shows public opinion. With new Coke, the media worsened the heard instinct by publicizing and making the protests viral.

Special Educational Needs Essay Example for Free
Special Educational Needs Essay This is a transition time for Special Educational Needs and Disabilities ââ¬â new legislation in the form of a green paper ââ¬Å"Support and Aspirationâ⬠is advancing through the necessary stages and considerable changes are promised to be implemented by 2014. An understanding of the historical perspective and the future proposals contained in ââ¬Å"Support and Aspirationâ⬠will therefore be helpful. Definitions: (From the current SEN Code of practice 2001) The Educational Act 1981 laid down a legal definition of Special Educational Needs in schools. That definition was repeated in the Educational Act 1993 and in the consolidation Education Act 1996. According to law: 1. A child has special educational needs if he or she has a learning difficulty which calls for special educational provision to be made for him or her. 2. A child has a learning difficulty if he or she: a) has a significantly greater difficulty in learning than the majority of children of the same age b) has a disability which either prevents or hinders the child from making use of educational facilities of a kind provided for children of the same age in schools within the area of the local education authority c) is under five and falls within the definition at (a) or (b) above. The following children fall outside the legal definition of Special Educational Needs a) Those whose language at home is different from the language in which they are taught at school b) gifted children Anticipated changes Summarized from https://www.education.gov.uk/publications/eOrderingDownload/Green-Paper-SEN.pdf The Green Paper, Support and Aspiration: A new approach to special educational needs and disability, sets out the governmentââ¬â¢s intention to radically reform the current system for identifying, assessing and supporting children and young people who are disabled or have SEN, and their families. The Green Paper proposals and the Governmentââ¬â¢s wider reforms in education and health will make the best use of limited resources through better planning, streamlining assessment processes, making the system less adversarial and focusing on achieving better outcomes. Reforms are already being tested through local pathfinders, developing the knowledge and skills that will be needed for their successful implementation, and making sure that the right measures are in place to hold services to account. The lessons learnt from the pathfinders will help shape the changes. In the Green Paper the government pledges by 2014 to introduce: â⬠¢ A single assessment process which is more streamlined, better involves children, young people and families and is completed quickly; â⬠¢ An Education, Health and Care Plan which brings services together and is focused on improving outcomes; and â⬠¢ An offer of a personal budget for families with an Education, Health and Care Plan. The government intends to introduce legislation through a Children and Families Bill to implement the changes to the law required for the Green Paper reforms. A draft bill will be published in summer 2012 for consultation and pre-legislative scrutiny. Application It is not yet clear how the changes will impact schools or what adjustments will be required in administration and ââ¬Å"grass-rootsâ⬠provision. Tutors will inform students of changes as they emerge.
Methods for Short and Long Term Memory Formation
Methods for Short and Long Term Memory Formation The purpose of the experiment was to determine which Learning Method was the most effective for short- and long-term memory formation. Method efficacy was tested via a Short-Term Memory (STM), and Long-Term Memory (LTM), glyph recall test. There were four groups, each using a different Learning Method which varied in two factors: written repetition (10X/none) and movie viewing (before/after STM test). The Learning Method was used to introduce the symbols, and there was a short maths test before the STM test. Symbol recall was assessed again in the LTM test, three weeks later. As the LTM test was taken after the STM test, all students had watched the movies. Analysis suggested that Learning Method 1 produced higher scores; students who wrote the symbol 10X and viewed the movie prior to taking the STM test had significantly greater glyph recall compared to those who used the other methods (p While Learning Method 1 appeared to be the most effective, it is possible that the results were affected by experimental design flaws; notably, the non-standardised test conditions. The degree of symbol retention demonstrated on the LTM test may be related to memory consolidation, which is aided by hippocampal ripple oscillations. The Learning Methods for each group were as follows (for the method code definitions and full method, see the Appendix): Group 1 (Learning Method 1): WB-1X_MB_10X Group 2 (Learning Method 2): WB-1X_MA_10X Group 3 (Learning Method 3): WB-1X_MB Group 4 (Learning Method 4): WB-1X_MA The independent variable is the Learning Method and the dependent variable is the number of symbols recalled correctly on the memory tests (STM and LTM). Method 1 was the most involved (writing 10X, and watching the movie beforehand). The alternative hypotheses are: Ha: if Short-Term glyph recall is related to the Learning Method (Method 1, 2, 3, 4), then students in Group 1, who used Method 1 (WB-1X_MB_10X), will recall a greater number of symbols correctly on a Short-Term Memory test. Ha: if Long-Term glyph recall is related to the Learning Method used for the Short-Term Memory test (Method 1, 2, 3, 4), then students in Group 1, who used Method 1, will recall a greater number of symbols correctly on a Long-Term Memory test. For the STM data, Leveneââ¬â¢s test established that there was an effect of variance (p p p p p = 0.8790) and those in Groups 3 and 4 (p = 0.9260). For the LTM data, Leveneââ¬â¢s test established that there was no effect of variance (p > 0.05). As the variance is not significant, a One-way ANOVA and Tukey post-hoc test can be used to test the hypothesis. The One-way ANOVA established that LTM test scores differed as a function of Learning Method used [F(3, 124) = 66.0280, p p p = 0.6160). The results support the alternative hypotheses that if glyph recall is related to the Learning Method used, then students in Group 1 (who used Method 1) will recall a greater number of symbols correctly on both a STM and LTM test. As the test scores for students who used Method 1 were significantly higher in both the STM and LTM tests, at a significance level of 0.05, the alternative hypothesis is favoured. By adopting the alternative hypotheses there is a possibility of Type 1 error in both cases. The hippocampus contributes critically to memory formation, organisation, and storage Memory consolidation, a process that transforms newly acquired information into long-term memory, also depends on the hippocampus. Through consolidation, labile newly formed memory traces are progressively strengthened into long-term memories and become more resistant to interference. However, it is suggested that they remain susceptible to updating and modification The hippocampus generates high-frequency ripple oscillations in local-field potentials (LFPs), observed most prominently in the hippocampal CA1 pyramidal layer Ripples participate in strengthening and reorganising memory traces, possibly by mediating information transfer to neocortical areas Memory traces are represented by assemblies of principal neurons that are activated during ripple-associated network states There is evidence suggesting that memory consolidation is enhanced during sleep and resting (ââ¬Å"off-lineâ⬠) states Sleep is a state which optimises the consolidation of newly acquired information in memory, depending on the specific conditions of learning and the timing of sleep It induces long-lasting cellular and network modifications responsible for memory stabilisation A proposed neural mechanism for sleep-dependent memory consolidation, is reactivation of awake experience (neuronal replay) in the hippocampus which is associated with sharp wave-ripple (SPW-R) events that occur primarily during off-line states SPW-Rs are ââ¬Å"aperiodic, recurrent instances of large deflections (sharp waves) in the hippocampal LFPâ⬠, and they are associated with synchronous fast-field oscillations (ripples) During SPW-R events, hippocampal cell firing closely follows the pattern that took place during the initial experience Theta (4-8 Hz) oscillations and ripples (~200 Hz) occurring during sharp waves may mediate encoding and consolidation, respectively. Pyramidal neurons replay previous waking activity in a temporally compressed manner, thus reactivated firing patterns occur within shorter time windows propitious for synaptic plasticity within the hippocampal network and in downstream neocortical structures. Slow-wave sleep (SWS) supports system consolidation and rapid eye movement (REM) sleep supports synaptic consolidation through specific patterns of neuromodulatory activity and electric field potential oscillations. During SWS, there is a diminution in cholinergic activity and the ripples stimulate the redistribution and transfer of hippocampus-dependent memories to the neocortex The thalamocortical spindles generated by the thalamus arrive at the neocortex at the same time as the hippocampal memory information, due to the slow oscillations which facilitate the transfer, and this synchronisation is thought to be vital to the long-term storage of memories within neocortical networks During REM sleep, at high cholinergic and theta activity, local increases in plasticity-related immediate-early gene activity may promote synaptic consolidation of memories in the cortex Incoming signals move through the hippocampus via a ââ¬Ëtrisynaptic loopââ¬â¢ consisting of synapses between principal cells in the dentate gyrus (DG), CA3 and CA1 Hofer et al investigated the cellular and network properties of SPW-Rs with simultaneous laminar multielectrode and intracellular recordings in a rat hippocampal slice model. Spontaneous SPW-Rs were generated in the DG, CA3, and CA1 regions During the memory encoding phase, the hippocampus binds neocortical representations to local memory traces. Then, during the off-line periods, the traces are concurrently reactivated in the hippocampus and cortex to potentiate the corticocortical connections underlying stored representations Studies show that disruption of ripples during post-learning SWS impairs memory consolidation and learning In an experiment conducted by Ego-Stengel and Wilson rats were trained daily in two identical tasks, each followed by a one hour rest period. Following one of the tasks, neuronal activity associated with ripple events was disrupted, without changing the sleep-wake structure, via selective stimulation of hippocampal afferents. It was found that the rats learned the control task significantly faster than the task followed by the stimulation, which suggests that interfering with hippocampal processing during sleep led to decreased learning Similarly, Nokia et al. found that disrupting hippocampal ripples using electrical stimulation either during training in awake animals, or during sleep after training, had a negative impact on learning A study by Wang et al indicated that the median raphe region (MnR) is important for regulating hippocampal ripple activity and memory consolidation. A fear conditioning procedure was used to determine this relationship, via interruption of ripple activity. Simultaneous in vivo recording in the MnR and hippocampus of mice showed that, when a group of MnR neurons was active, ripples were absent; ripple activity was related to the activity of MnR neurons. Additionally, MnR may regulate memory consolidation via its projections to thalamocortical regions, which facilitate interactions between the hippocampus, thalamus and cortical regions during SWS. Under the assumption that there was little deliberate reactivation of memory traces for the symbols in the three weeks following the STM test, the degree of retention of the symbols on the LTM test may be related to memory consolidation via hippocampal ripples occurring during sleep and rest. There were a number of limitations which may have affected the validity of the results. The major limitation was the non-standardised test conditions. Since different groups took the test at different times of the day, and different individuals have performance peaks at different clock times randomisation of subjects is important. This also leads to the possibility that students in an earlier group may have informed others of the symbols or experimental procedures. Knowledge of the tests could have influenced the studentsââ¬â¢ concentration, with those who knew being more likely to apply themselves to the Learning Method. While all students would be likely to undergo some degree of memory consolidation following the STM test, those who were aware of the experimental design would likely have greater retention. If all students took the test at the same time under standardised conditions, it would be less likely for this issue to affect the results. Additionally, the small sample size, and the fact that the participants were all students of one course (Neuroscience), also means that the external validity of the experiment, and thus the generalisability to groups other than the experimental group, cannot be established. There was also only one group per Learning Method, so it is unknown if the results are repeatable.

Identity Conditions for Indicator State Types within Dretskes Theory of :: Psychology Dretske Papers
Identity Conditions for Indicator State Types within Dretske's Theory of Psychological Content Naturalization ABSTRACT: Within the context of Dretskeââ¬â¢s theory of psychological content naturalization, as laid out in Explaining Behavior, the concept of an indicator state type plays a pivotal role. Providing a general (and non-circular) description of the identity conditions for being a token of an indicator state type is a prerequisite for the ultimate success of Dretskeââ¬â¢s theory. However, Dretske fails to address this topic. Thus, his theory is incomplete. Several different approaches for specifying these identity conditions are possible; however, each is inadequate. Of the various theories for psychological content naturalization put forward within the past two decades, I believe that a Dretske-style approach that explains the content of a mental state in terms of the causal history of past tokens of that state holds out the most promise of giving us a workable theory describing the role that content plays in learned behavior. While I favor this general approach, the particular theory laid out by Dretske in Explaining Behavior has a shortcoming that must be addressed before his theory can be applied to real systems: Dretske fails to provide an analysis of identity conditions for being a token of an indicator state type. The shortcoming is serious because of the critical role that past tokens of an indicator type play in fixing the content of a current token of the indicator type ââ¬â without identity conditions, there is no way to specify which previously tokened states among the many that have been instantiated during the learning period of the organism are of that indicator type. I begin with a very brief review of Dretske's theory from Explaining Behavior. Some organisms possess indicator states (i.e., internal states that indicate whether some external conditions hold). For example, organism O may token an instance of I (the internal indicator state type) whenever external conditions F obtain. Prior to learning, I indicates F does not mean F. Let's suppose that external conditions F are relevant in some manner to O's continued functioning, perhaps because environments in which F obtains are environments that are relatively inhospitable for O. Let's also suppose that O is capable of learning using reinforcement information (via operant conditioning), such that future tokenings of I come to cause movements that are appropriate to conditions F. (My use the evaluative term "appropriate" here rests on two assumptions: (1)
Nursing and Biomedical Research :: Health Care, Nurses
With unparalleled technological advancement, nursing and bio-medical research, and the present healthcare environment, nurses must be cognisant of their professional and personal views of ethics. Ethics are standards of behaviour, developed as a result of ones concept of right and wrong (Judson & Harrison, 2010), and are intended to influence the actions of healthcare professionals. Ethical principles help guide the decision-making process among healthcare workers in complicated situations. [Therefore] we cannot understand nursing unless we also understand ethics (Gallagher & Wainwright, 2005) There are many different ethical theories which can mainly be divided into three groups. These are Duty based, Goal based and Rights based theories. Deontology is a duty based ethical theory. This means that a moral person must always do their duty and must perform them ââ¬Å"without exception, whatever the consequencesâ⬠(Seedhouse, 2001). However, this theory has limitations and objections because it does not allow for conflict between duties, flexibility or compromises and these are all essential for health work. (Seedhouse, 2001) Goal based theories such as Utilitarianism, believe that what is morally right is determined by the good that is produced as the consequence of the action. The acts that achieved this were defined as ââ¬Å"goodâ⬠and those that produce ââ¬Å"painâ⬠were bad. (Rumbold, 2000) An objection with Utilitarianism is that because it is only concerned with the consequences, then even if an action was taken that was intentionally bad, it would still be ethically right if the eventual consequences were favourable. (Seedhouse, 2001) Dunbar (2003) states that there are four main ethical principles, these are beneficence, non-maleficence, justice and autonomy. The principle of beneficence is to do good for patients and to put their needs before your own (Rumbold, 1999 p217) and with beneficence comes the principle of non-maleficence meaning to do no harm. Rumbold (1999, p222) describes how in many nursing duties nurses have to ââ¬Å"do harmâ⬠to our patients but only when it is alongside beneficence and the long-term goal is to do good by the patient. In not giving a patient assistance to eat their meals we are acting in a manner that these principles donââ¬â¢t support as there is no good that could arise from this. Beneficence is considered to be the caring ethic, as it guides us to work in the best interests of the patient but at the same time for the benefit of other patients, considering their rights to justice and fairness with their care (Kennedy, 2004).

Adult Learning Today Essay
Summary Adult learning has become the number one priority in everyoneââ¬â¢s lives. The motivation and drive that is brought on by dreams and goals is phenomenal. Adult learners must be motivated to want to further their education. ââ¬Å"Back in the 20th century various individuals, such as John Dewey, Eduard Lindeman, and Martha Anderson all pursued theories about Andragogy which was first used by Alexander Kapp in 1833â⬠(Abela J, 2009). Andragogy means man and was used to describe the educational theory of the Greek philosopher Plato. Adults engaging in continuing education were studied in this theory. Andragogy assumes that ââ¬Å"adults are independent, have various experiences, are motivated by internal drives, and integrate their learning into everyday lifeâ⬠(Abela J, 2009). It is easier to learn and teach when it is something that is well known. This article covers Andragogy learning theory because it is used now a day more than ever. The drive that keeps continuing education is oneself. The drive to motivation is based off of the Hierarchy of needs: self-actualization, esteem needs, social needs, safety needs, and physiological needs. The role of educators is the catalyst for motivation. It is easier to learn when the person teaching is knowledgeable and cares about the education aspects. However, reflection and motivation are insufficiently addressed by this concept. Learning activities should address the knowledge, skills, and attitudes to what is needed to become knowledgeable in retaining the information. Feedback when learning new information becomes an important role so that one may know whether the information is being comprehended as well as being retained for further use. Adults find motivation within the demands and desires of their lives, in providing for themselves and for their families, and in satisfying personal dreams and ambitions. Motivation may also come from inside a person or the surrounding environment. In everyday life as well as in the work aspects furthering education is the best way to stay up to date. Andragogy is a great theory and is used in everyday life more than realized. Reflection By looking into the reasoning behind all my motivation there are the answers I have always tried to find. What am I working towards? For who? I am an adult learner and motivation is key to my life and what I want out of it. Motivation is my drive to furthering my own education. Andragogy actually describes me perfectly. I am motivated, independent, and I apply all my knowledge to everyday life. It helps greatly when professors and educators actually work with you and help you better understand the information being taught versus just being a ââ¬Å"teacherâ⬠for the money. I feel as if teachers online especially have lost sight of the education aspects. Left out from the summary Andragogy is a popular theory used in medical education. Theory works perfectly into my life even though I am a Business major; I also have the drive to help the elderly, so I am a certified nursing assistant. My professors have been there for me and helped me greatly. My learning style is independent much like Andragogy but, I also have to apply everything I learn into everyday life or I wonââ¬â¢t be able to retain all the information given. Motivation is the key to anything you want to achieve in life and motivation is what keeps me going during the long work weeks and the long school hours. If one concept doesnââ¬â¢t work then move onto another concept until the learning style clicks. In this article the medical field and this adult learning theory works exceptionally well. Although this may be just another theory, it is of great importance to the adult learners furthering their education. We can better understand the world around us and how things are done if we understand how to retain the information given. As a full-time student, young mom, and full-time worker, online education has been more than helpful. It is my motivation to finish my associates, then finish out with my bachelors, and move forward to the next steps in my life. They say, ââ¬Å"You canââ¬â¢t teach an old dog new tricksâ⬠, teach things the first time and use all concepts needed and you will soon achieve life goals. By furthering your education you may open up doors and opportunities you would not have gotten if you had not decided to go to school. Education is the best decision you could make for yourself as well as to make the world a better place by being educated. Works Cited Abela, J. (2009).
