To summarise the Multi Store Memory Model Essays - Memory To summarise the Multi Store Memory Model: The Multi Store memory model is a structural model composing of 3 completely separate memory stores where information passes across in a linear way. The 3 stores are: The Sensory memory store The Short-term memory store The Long-term memory store Each have their own unique characteristics. The Sensory Memory receives information from the environmental stimuli through sight, hearing, touch, taste and smell however this is usually ignored for the most part. If this information is given Attention then it begins to pass into the short-term memory store. The Short-term memory store has a capacity of 7 +/- 2 items and a duration of up to 18 seconds with information encoding being auditory. Information is prone to decay and forgetting or displacement if new information arrives. If rehearsed deep enough through elaborate or maintenance rehearsal, information then transfers over to the Long-term memory store which has unlimited duration and capacity and information is encoded semantically. Here information can be recalled through retrieval at a later stage once processed. Evaluating the working memory model The working memory model (Baddeley & Hitch, 1974) Replaces the unitary short term memory concept of the multi-store model Separate processing resources for auditory and visual short term memory Explains the memory deficit caused by KF's brain damage The working memory model has many strengths over the multi-store model. It describes short term memory as a collection of active processing mechanisms that work in two modalities (verbal and visual) rather than a single store that simply rehearses verbal information. This allows it to explain memory function in patients with impairments to one component of working memory but with normal function in the other components, such as KF. There is considerable research evidence for the existence of the individual components of working memory (see section above). The major weakness of the working memory model is the central executive which, ironically, is its most important component. There is relatively little research evidence for its existence and it is by its nature very hard to directly investigate, although some recent research into patients with Alzheimers disease (e.g. Baddeley et al, 1991) has identified how an impaired central executive may affect memory function. The problem with researching the central executive is that it cannot itself be measured directly, and instead its function has to be inferred from performance at verbal and visual tasks. When we want to measure the functioning of a component we give it a task designed to reduce its performance, such as occupying the phonological loop with an articulatory suppression task. If participants are able to perform the task then researchers conclude that the central executive is working properly, but if they perform the task poorly then they conclude that the phonological loop is impaired. In other words it is impossible to design a task that effectively tests the central executive without also affecting its slave systems, and so the central executive may never be adequately investigated and it will always remain a concept with limited support - Richardson (1984) calls this the circular argument.

Hand hygiene - Essay Example In this section I shall dwell on the advantages that re are associated with children in their Early Years interacting with the outdoor environment and the benefits that is brings to their development. From the literature review, it can be concluded that education in the Early Years is dependent on the outside space since it can be considered as a natural place for exploration, engagement and one that provides a motivation for learning. Active learning, exploring as well as creative thinking, enhances effective teaching and learning which are all influenced by the kind of environment that the education takes place in. Play forms a very important aspect as far as the development of children is concerned, their learning as well as their wellbeing and it is vital that the practitioners appreciate, value and maintain the play that is associated with children all through the Early Years (Lillemyr, 2009, p. 8). The provision of a good quality outdoor environment can affect the confidence that the children have as well as their independent learning but it should be noted that this is not a sole entity since it is comprised of various activities that have discrete purposes. From the interviews that were conducted with the practitioners, it was clear that outdoor play is advantageous since it basically allows the children that engage in it to have fun while playing while they engage and explore the natural environment and all this works towards their development. This natural setting develops the skills that the children have naturally while making them more confident in the things that they take part in as the grow. From the literature review, there is also the suggestion that the outdoor environment also provides chances that create an equilibrium between the structured activities that are guided by the adults and allowing the children to interact with their particular outdoor spaces. This enables the children to use their

Absolutism and Limited Monarchy Essay Example | Topics and Well Written Essays - 250 words

Absolutism and Limited Monarchy - Essay Example riod in England where parliament of England was known to have strong political interests in the country and this threatened the monarch (Duiker and Spielvogel, 2006). France and central Europe had strong Catholic roots and hence the Protestants who were known to interfere with monarchy system had no voice. These countries also had strong traditional sources of revenue that they used to run their monarch and this made even the nobility and other political interests in their countries to be at their mercy. This too place in around 1850s and it tossed aside the option of having a limited monarch (Perry, Chase, Jacob, Jacob and Von Laue, 2008). Compare the classical absolutism of Louis XIV in France with one other ruler, Kangxi of China who ruled from 1661 to 1722, Peter the Great of Russia who ruled from 1689 - 1725, or Aurangzeb, Mughal emperor who ruled India from 1658-1707. Both Louis XIV of France and Kangxi of China ruled using â€Å"iron hands.† They were the two longest serving absolutist rulers in their respective countries and this way possible due to their ruling style and dictatorship manner. They both had wealth from the revenues they collected from their countries and from the countries they went to war with and they both had their religious issues and even political issues in check and hence avoiding any disruption of their ruling (Duiker and Spielvogel, 2010). All absolutist leaders including Louis XIV had monetary stability to rule. The funds enabled them command even the military to fight enemies, conquer areas and put wealthy people at their service. They also had almost similar goals and tough rules that made them strong and relentless in their ruling. The difference however came in their personal life and how they had been raised up. Some had tough childhoods like Kangxi but others like Louis XIV and XV had it smooth and hence this affected how they imposed their ruling (McNeese,

Joseph Vissarionovich Stalin and his Crimes against Humanity Essay

Joseph Vissarionovich Stalin and his Crimes against Humanity - Essay Example From the essay "Joseph Vissarionovich Stalin and his Crimes against Humanity", it is clear that the theme of perfect loyalty is one of the integral themes perpetuated through all his crimes. In 1924, only 25% of the Russian population was located in cities, the rest of the country lived in agriculture villages. Stalin realized that the power was in the hands of those who owned the land. Power meant financial gain. He set out a plan to manipulate the people in believing that he was their new god by replacing the Orthodox Church. He also demanded perfect loyalty from the kulack in the Centralization plan. When Lenin came to power in 1917, he offered territory to the peasants (kulak). It was Stalin's plan to take back the territory and rid them of all power. There are three things that bound each family: faith, the Tsar and the fatherland. Ridding each family of these three icons and creating new images would give Stalin ultimate power. Stalin banned religion, replaced icons with photos of himself. He had to change the outlook of the fatherland. He understood the power of the media. Every time he made a speech, he had it recorded on a vinyl record. He made sure each village had a gramophone and received records of each of his speeches. Villagers were impregnated with Stalin. He became their faith and their Tsar. In 1924 Russia was a poor country with an abundance of natural resources. These resources could be exchanged for technology and other goods which would assist Russia in becoming an industrialized country. Within three years of power, Stalin initiated his 5 year plan: A peasant society to a World Power. Historian John Brent from Harvard University (Man 2008) and Historian Mark Kramer from Yale University (Stalin 2007) explain the reasons backing centralization. Technology was expensive. One way to pay for it was to centralize the agricultural fields of Russia and use the goods as an export commodity. "Centralization was an answer to the Bolshevik revolution and the chaos that followed. It was rationalized that it was the only way to meet the economic and structural needs of the economy". (Gouldner 1978) The last reasoning behind centralization was the simple fact

Pathway to Becoming an Engineer Essay Example for Free

Pathway to Becoming an Engineer Essay Engineering is both a discipline and a profession that mostly deals with the application of technical and scientific knowledge by the specially trained engineers. It involves the utilization of natural laws and physical resources in order to design and implement materials, structures, machines, devices, systems and processes which are aimed at realizing desired objectives in accordance with a specified criteria. These engineers apply scientific knowledge gained from such fields like mathematics and physics in order to find solutions to problems The engineering profession is among the few highly prestigious professions in the United States and as parents responded to a survey they said that they would like their children to enroll in such a profession. This being a fact it is important for those aspiring to be engineers to have some knowledge about the main requirements necessary for one to enroll for an engineering course. It is a necessity for the aspirant to have a good foundation in the science based subjects in high school as these act as prerequisite for good performance in the engineering courses. This includes such subjects like Mathematics, Biology,Physics,Chemistry, Mechanics and computer knowledge. The students should also have good knowledge in English and the Social Sciences since they also form part of the program in the university. Apart from being good in the class work more is also expected to have some character traits From a study done by Ross Harrison (1955) mechanical engineers were found to be emotionally stable without any neurotic symptoms, goal oriented, serious minded, energetic while advocating for direct action when faced with problems. Other character traits found in the mechanical engineers was that they were straight forward people who rarely show analytical interest in other people. They also avoid introspection and self examination as revealed by the study. In addition they are expected to be trustworthy, honest, and maintain high levels of integrity(Carbajal 2006). From these studies learners should seek to develop these traits although it is not such a requirement. Pre-college activities There exists some program which students preparing to join engineering courses at the university can participate in. Most of these programs are organized by universities and are called Summer Programs. One such program that students can participate in is the Summer Undergraduate Program in Engineering Research at Berkeley (SUPERB). It is an eight weeks program that prepares students before they enroll for their studies and gives them an opportunity to participate in the area of interest. Another internship program that high school students can enroll in is the Science and Engineering Apprenticeship Program which is sponsored by the office of Naval Research and offered annually. There are many summer programs related to engineering studies but they take the already registered students during the summers. Main branches of Engineering. Engineering is a broad discipline which is often broken down into several sub disciplines all of which do concentrate on different areas of engineering work. Over history the major renown branches of engineering are; Aerospace (dealing with aircraft and spacecraft),Chemical(dealing with conversion of raw materials in to usable commodities),Civil(deals with design and construction of private and public works like bridges building), Electrical engineering which deals with design of electrical systems, Mechanical Engineering which deals with design of physical or mechanical systems, Computer Engineering dealing with design of software and hardware integration. With advancement in technology new fields are coming up. Such fields include Software Engineering, Molecular Engineering, Mechatronics and Biomedical Engineering. Top engineering colleges in the U. S According to the ranking done by Graduates Hotline 2006 the best universities in engineering were ranked as, Massachusetts Institute of Technology being the best followed by Stanford University then third placed was University of California-Berkeley. The others were California institute Technology, University of Illinois at Urbana-Champaign, Georgia Institute of Technology, University of Michigan, Cornell, Carnegie Mellon and University of Texas at Austin in that order of the top ten institutions. How to find engineering colleges There are about 1,830 programs at colleges and universities that offer bachelors in engineering and in order for one to locate the best he/she should consider whether they are accredited by the Accredition Board For Technology(ABET). The student should investigate the curriculum and check accreditions carefully before selecting a college. This because programs may have the same name but vary in terms of the content to be covered. Enrollment into engineering There has been an increase in enrollment for graduate students in science and engineering fields in the U. S. Full time enrollment increased by 16% in the year 2006 to reach a peak of 343,603 students and this comprised of both foreign and U. S. Citizens(Oliver 2007). This increase was in all engineering subfields except for civil, agricultural and computer sciences. Typical first year engineering class. Different institutions have different first year programs for their engineering students. But in majority of the institutions students spend most of their first year while studying mathematics(Calculus,Algebra,Geometry) and basic sciences like Physics, Biology and Chemistry It is called the first year engineering transition program which helps students to upgrade their Grade Point Average and improve their academic standing. It also helps the students to prepare adequately for the subsequent years of study. The typical first year class is usually divided into two semesters with specified courses of study for each semester. These are the winter semester and the summer semester. The bachelors program is designed to last four years but mostly students find themselves taking up to five years to complete their degree programs. Importance of internships for students. The internships usually offered during the summer periods provide valuable experiences for the students. This because they provide first hand perspectives of a career and as such begin to realize the value of their courses. Through internships students develop essential skills that are required on the job. Again they create opportunities through which students understand what is expected of them in the industry. They also explore their career in order to apply their skills and talents which rhyme with their interests. Internship periods have also been know to be transformative since during such times the students meet and overcome many challenges that come their way. This increases their confidence and drive to learn to achieve. Licensure All states in the U. S require licensure of all engineers who offer their services directly to the public. Those who manage to get the license must be in possession of a degree from an accredited institution in addition to four years of relevant experience. They are also expected to sit and pass a state exam. After getting the license they are then referred as professional engineers. Salaries and employment for engineers The earnings for engineers vary depending on speciality ones level of education and the industry one works in. In the federal government the mean annual salaries for engineers in the year 2007 ranged from $75,144 in Agricultural engineering to $107,546. when all other groups of employees are considered it is the engineering group that earns the highest average starting salary. In the same year engineers held about 1. 5 million jobs in the U. S. Out of these jobs 37% was in the manufacturing industries while 28% was in the professional sector. As regards the federal state employment it employed 12% of all the engineers while 3% took consultancy as a form of self employment. One thing that is important for practicing engineers is for them to continue upgrading their education throughout their careers. This is because employers will attach more value to highly trained engineers as opposed to those who are not highly educated. Again promotion in this profession is closely associated with the level of education and as such the highly educated ones end up getting promoted easily. As mentioned earlier engineers play a very significant role in the society since they provide solutions to most of the problems that the society face. Therefore we can not under emphasize the role they play in the society as they apply scientific knowledge in meeting the societys need. They are viewed as very important people in the society and thus they should maintain the integrity in serving the society in line with the professional code of conduct.

Solar System Essay -- essays research papers

The Solar System By â€Å"Delete this text and type your name here.† Introduction As far as we know, there are nine planets locked in orbit around the Sun. Only one, our own Earth, supports life. But there are countless other suns throughout countless galaxies scattered across the expanse of the universe. We still don’t know if life exists on another planet in some other galaxy. Mercury Named for the wing-footed messenger of the Roman gods, Mercury races around its orbit at a dizzying speed of 30 miles (48 kilometers) per second, making the Mercurial year only 88 Earth days long. In contrast, one rotation around its axis—or a single day—takes almost 59 Earth days. Geology Mariner 10 gave us a wealth of information about Mercury when it approached the planet in 1974 and 1975. Because Mercury has no water and barely any atmosphere, no erosion has taken place on its surface. We see Mercury much the way it was soon after it formed. Core We learned that Mercury has an extremely weak magnetic field, which could indicate a hot metallic core, such as molten iron. Geologists think Mercury may be the most iron-rich planet in the solar system. Crust Mercury’s crust seems to be silicate, like that of Earth. Craters The planet’s surface, viewed for the first time via Mariner’s cameras, is covered by craters. The battering occurred during the early period of the solar system when clumps of material were ramming into each other to form the planets. Atmosphere Mercury doesn’t have what we think of as an atmosphere—that is, a gaseous envelope that produces clouds and weather or protects the surface of the planet from some of the harmful solar radiation. The weak magnetic field on Mercury captures only the barest perceptible trace of charged particles from the Sun. Venus Shrouded in the cloak of mystery, Venus, our nearest planetary neighbor, takes the name of the Roman goddess of love. For some unknown reason, Venus rotates on its axis in retrograde—that is, in the reverse direction of its revolution around the Sun. Geology Geologically, Venus appears to have some similarities to Earth. Its crust is probably granitic, overlying a basaltic mantle and a iron-nickel core. The geologic activity that we are familiar with on Earth seems not to exist on Venus, except for the presence two volcanoes along a fault line. ... ...p;  17 Uranus  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  19.18  Ã‚  Ã‚  Ã‚  Ã‚  84 years  Ã‚  Ã‚  Ã‚  Ã‚  16 hours  Ã‚  Ã‚  Ã‚  Ã‚  14.54  Ã‚  Ã‚  Ã‚  Ã‚  4.10  Ã‚  Ã‚  Ã‚  Ã‚  15 Neptune  Ã‚  Ã‚  Ã‚  Ã‚  god of the deep blue sea  Ã‚  Ã‚  Ã‚  Ã‚  30.06  Ã‚  Ã‚  Ã‚  Ã‚  165 years  Ã‚  Ã‚  Ã‚  Ã‚  18 hours  Ã‚  Ã‚  Ã‚  Ã‚  17.23  Ã‚  Ã‚  Ã‚  Ã‚  3.88  Ã‚  Ã‚  Ã‚  Ã‚  8 Pluto  Ã‚  Ã‚  Ã‚  Ã‚  god of the underworld  Ã‚  Ã‚  Ã‚  Ã‚  39.44  Ã‚  Ã‚  Ã‚  Ã‚  248 years  Ã‚  Ã‚  Ã‚  Ã‚  6.4 days  Ã‚  Ã‚  Ã‚  Ã‚  .002?  Ã‚  Ã‚  Ã‚  Ã‚  0.12-0.30  Ã‚  Ã‚  Ã‚  Ã‚  1 * AU = Astronomical Unit (Earth = 1) Conclusion We know more and more all the time about our own solar system. During the past 15 years, space probes such as the Mariner and Voyager missions have given us tremendous detail about all the planets in this system. Tiny by comparison to the Milky Way, our solar system is awesome, nevertheless, when considered in human scale.

Interprofessional Collaboration

Interprofessional communication and collaboration are a significant part of ensuring safe and effective patient outcomes. In the case detailed below the health care team failed to communicate and collaborate care of patient A, ultimately leading to a negative outcome. Patient A is a female white 38 year old G1P0 with Type I diabetes since the age of 9. Due to her high risk pregnancy and history of non compliance with medical therapy she had been coming in since 28 weeks gestation for twice weekly non stress tests. One Saturday as patient A was at the hospital for her non stress test she was found to have elevated blood pressure and proteinuria. Dr. A, an obstetrician (OB), who was on call for the weekend decided to send the patient home on bed rest and to follow up with her primary OB physician, Dr. B on Monday. At her follow up appointment with her primary OB, she was found to still have elevated blood pressures, blood sugars in 200's, 2+ protein in her urine and had some elevated blood work. Primary OB decided Patient A needed to be induced due to patient A’s unstable condition. Primary OB is not on call this particular Monday and asked Dr. C to induce her patient. Dr. C was not happy about inducing her because of her high risk status but agreed to do so. Dr. D, a laborist and pediatrician, wanted the patient transferred to a higher level of care facility because he felt due to patient A’s history best care for the newborn would be at another facility. Dr. D and Dr. C argued about patient A’s care and disposition at the nurses’ station which was in close proximity to patient A’s room. The nurses who were without a manager at the time were unable to control the altercation between Dr. C and Dr. D. Patient A who overheard the discussion eventually asked to be transfer to another hospital to seek care elsewhere. This paper highlights the importance of effective interprofessional collaboration that is missing in this case. As well, potential plans of action and potential outcomes are discussed. Plan to Address Conflict The major conflict in this situation was a lack of communication between providers regarding the best plan of care of the patient. In addition to the obstetrician, members of the interprofessional team should include the pediatrician, a nurse leader, and the patient. Legare et al (2011) describes a stepwise approach to interprofessional collaboration and the shared decision-making process. The members of the interprofessional team must start by exchanging information and options available related to the care of the patient. Next, the values of both the patient and the healthcare providers should be clarified and addressed. The feasibility of each option should be weighed. Often, certain options are not feasible based on resources or time. In this case, the skills and comfort of the healthcare team members needed to be considered. Once a decision is made, the information needs to be disseminated, including the plan of care and rationales for the decision made. SBAR (Situation, Background, Assessment, and Recommendation) is a useful tool in succinct and structured communication. (Boaro, Fancott, Baken, Velji, & Andreoli, 2010) To prevent future situations similar to this one, Standard Operating Procedures, or SOPs, should be developed and followed. These SOPs should address staff competency, scope of practice, role clarification, and the resources and limitations of the facility. The interprofessional team should develop these SOPs together to ensure they reflect the values of the involved disciplines. (Gardner, 2010) Additionally, resources are available to aid hospitals in developing a structure for interprofessional collaboration. A national interprofessional competency framework detailed by the Canadian Interprofessional Health Collaborative (CIHC) provides an integrative approach to describe competencies required for the interprofessional collaboration to be effective. They are as follows: (1) interprofessional communication (2) patient/family centered care (3) role clarification (4) team functioning (5) collaborative leadership (6) interprofessional conflict resolution. (CIHC, 2010) CIHC suggests that having a competency framework because it helps the team make sense of the learning practice, it will differentiate matters by relevance, give the team members a chance to apply the learning to practical situations and then associate the learning elements by integrating them. CIHC, 2010) When this patient arrived to the unit, if the team had used the six suggested competencies providing best care for this mom and baby could have been achieved easier. Discussion of Outcomes The intent of interprofessional collaboration is one that will foster the safe practice of all health care professionals, and enables the achievement of better outcomes. Some outcomes needed for this particular situation would be as followed: 1. Shared decision making between all pr oviders involved. What is the best practice that can be provided for a safe outcome for mom and baby? Inducing the mom because it was best practice was made by the OB, but she didn't factor in safe practice for the pediatric doctor in this situation. 2. Demonstrate professional conduct during inter professional collaboration. Make sure if there are any discussions with team members, disagreements with the care that is being provided that it is not done where the patient can hear it. 3. That the interprofessional team can acknowledge the various skill levels of everyone involved. The pediatric hospitalist is this situation felt that the patient’s diagnosis of Type 1 diabetes, uncontrolled throughout the pregnancy put the baby at risk for having glucose controlled problems and felt that a higher level of care was needed because it was beyond his skills set. Interprofessional collaboration was necessary in this situation. No one discipline has all of the knowledge needed to provided complete patient-centered care. True interdisciplinary patient-centered care includes a partnership between health care professionals as well as the patient. This collaborative and coordinated approach improves patient outcomes and quality of care (Orchard, Curran, & Kabene, 2005). In this case, the interprofessional team failed to communicate effectively. This lack of communication and professional conduct led to a failure to recognize the skill levels of the team members, and prevented the team from making a shared decision that would benefit the patient. Conclusion In order for patient A to achieve a positive outcome several factors related to interprofessional collaboration needed to be addressed in this case. First, to improve collaboration and understanding, clear team roles of the health care providers should be defined. Scopes of practice as defined by standard operation procedures and discussions of available resources should be taken into account. In addition, distribution a consistent communication tool such as SBAR could be used. Had the healthcare providers involved with this case practiced as a team, positive outcomes such as: open communication, trust, professionalism and improved patient outcomes and experiences would have been achieved.
