Integrated Science, Hurricanes Definition Causes and Precautions Essay The winds weaken with height.  · The centers of the hurricane are warmer than their surroundings  · They form under weak high altitude winds.  ·The air also sinks at the center of a hurricane and the main energy source is the latent heat of condensation.  ·They weaken rapidly over land. Definition: A Hurricane is an intense tropical weather system with a well defined circulation and maximum sustained winds of 74 mph (64 knots) or higher. In the western Pacific, hurricanes are called typhoons, and in the Indian Ocean are called cyclones. Hurricanes are products of the tropical ocean and atmosphere. Each year on average, ten tropical storms (of which six becom become hurricanes) develop over the Atlantic Ocean, Caribbean Sea, or Gulf of Mexico. Many of these remain over the ocean. Howevever, about five hurricanes strike the United States coastline every 3 years. Records of hurricane in the Caribbean:  ·Anguilla Hurricane Earl 2010 Antigua Barbuda Hurricane Debby 2000 , Hurricane Omar 2008 , Hurricane Earl 2010  ·Babrbados Hurricane Joyce 2000  ·Haiti Hurricane Isaac -2012 , Hurricane Hanna 2008 , Hurricane Ernesto 2008 , Hurricane Kyle 2008  ·Grenanda- Hurricane Emily 2005 Evacuation Safety Procedures: (Hurricane) When a Warning or Hurricane watch is occured :  ·Leave low lying areas.  ·Protect windows with plywood boards, or storm shutters.  ·Secure outside objects.  · Make sure you have plenty of fuel and water.  ·Have several days supply of food and water for each family member. If called to evacuate, do so immediately. Before the storm: -Stay in Secure Room. -Stay away from windows. -Do not use the phone, or candles. -Have supplies on hand. -Remain indoors when the eye moves over your area because the storm will resume shortly. After the storm:  ·Make sure that all is definitely clear outside, and the storm has completely passed before going out.  ·Report downed power lines, and stay away from them.  ·Use stored water and food.  ·Be patient. Things will take a while before they get back to normal.

Pluralistic Extension System :: Politics, Government Programs

Definition Pluralistic extension system is provision of extension services for a community which is conducted by more than one source of extension services (Okorley, Grey, & Reed, 2010). According to Rivera & Alex (2004), pluralistic extension system may hold complex providers like non-governmental organizations, private companies, farmers’ organizations, commercial individuals, extension specialists’ associations, and public extension services at municipal, state, and national. Non-pluralistic extension system, by definition, is single provider of extension service which is conducted by only public extension agents. It is clear that pluralistic extension system do not eliminated the public extension workers from the system, but the system adds other potential extension agencies along with the existing public extension agency. Why is it necessary? There are several reasons why pluralistic extension system is required. One of the reasons is that previous single provider of extension system, mainly Training and Visit (T&V system) was criticized for its limited advantages. As the case in India, the T&V system was blamed for only boosting commodity and supply-driven but not generate income. It was also criticized as the cause of the fall of commodity price, disintegration among sub-sectors, and poor focus on farmer organization development (Singh & Swanson, n.d.). Former extension system was occasionally considered as inefficient, having unclear and incompatible objectives of state intervention, vague rules for implementation; it also provides limited incentive for extension workers, and lack of financial transparency (Rivera & Alex, 2004). Moreover, the pluralistic extension system is expected to reduce financial burden of national government due to large institutional structures and perceived ineffectiveness of former extensio n system (Swanson & Rajalahti, 2010). Earlier extension system was also blamed for not giving much attention in involving farmers to define and solve their own problems, while having poor linkage of extension-research-farmer system (Davis, 2008). The support of farmers’ group as possessing power for extension provider comes from Davis’ research in Kenya (n.d.), in which she found that farmers’ groups were considered by local farmers as credible source of agricultural information provider (Davis, n.d.) What are the main dimensions? Rivera & Alex (2004) maintain, â€Å"extension is not necessarily a government program, but rather the complex set of institutions whereby rural people obtain new knowledge and information† (p. 339-340) and it allows the possibility of differences extension system among different countries. This proposition has led to the implication that the dimension of (pluralistic) extension system could cover variety of issues like policy implementation (for rural change or mobilization), information collection, particular salient issues (like health problem: HIV/AIDS, etc.

Careers in Psychology Essay

Career Options After Pursuing a Degree in Psychology Choosing a major or a degree field to go into after graduating from high school is one of the more difficult things that recently graduated young adults have to go through. Many different aspects of a future career field are evaluated to help the individual in choosing the best career path for them. These evaluations include required education, salary, future places of employment and most importantly, what an employee in this specific area of employment will be doing. Choosing to earn a degree in Psychology offers many different possibilities for future areas of employment that can fit almost any type of person. In addition to the diversity of the field, the U.S. Bureau of Labor Statistics predicted an increase in psychology job opportunities over the next decade due to increased demands for these services in education, law, hospitals, and private companies along with many more options (BLS, 2010). With so many different areas of society requiring these services pursuing a degree in psychology opens up many career paths outside the commonly stereotyped job description of psychologists. Even though many people assume that clinical psychology or other types of therapy are the only options with this degree, an individual in this study can go into fields such as neuropsychology, developmental psychology, and educational psychology. A neuropsychologist is one who has received a doctoral degree, typically a PhD, from an accredited American Psychological Association university along with completing the one year internship required for the degree, and a two year training period within a neuropsychology practice (Moberg,2006). The job description includes, studying the relations among brain structure and behavioral, cognitive, emotional, and sensory and perceptual functions along with the diagnosing and treatment of disorders related to the central nervous system. Most neuropsychologists organize and conduct academic  research relating to the aforementioned topics, along with assisting and witnessing testimony in court cases that involve judgment to the psychological conditions of the people involved. Outside of the court system, neuropsychologists usually work in laboratories, along side medical professionals at hospitals, or privately making starting salaries between $60,089 and $91,476 annually. After some years of experience an accredited neuropsychologist can make anywhere up to $300,000 a year, but the average yearly salary as of 2010 was approximately $127,460 (BLS, 2010). On top of earning a relatively large wage neuropsychologists report to having overall high job satisfaction, with less than twenty percent of them considering changing jobs or leaving the psychology field for a different one all together (Moberg, 2006). Being strongly interested in the functioning of the central nervous system and wanting to go into an area of research would make neuropsychology a top choice for anyone interested in pursuing a doctoral psychology degree. For a person who is more interested in a field dealing with people as a whole and not just the internal functioning of them, developmental psychology could be a possible career option. A developmental psychologist is someone who studies human growth and development that occurs throughout the entire lifespan. This includes biological development, but also focuses on cognitive, social, intellectual, personality, and emotional growth. Although the specific tasks of the psychologists vary based on the area they specialize in, most of them perform research and evaluations in the area of their study, such as studying a particular age range (Beilock, 2012). For example one could study how moral reasoning develops in children, or how people influence the personalities of others. Many developmental psychologists work in educational settings at colleges or universities where they conduct research as well as teach courses. Others could possibly be employed at teen rehabilitation centers, psychi atric clinics, government agencies, etc. The education required to become a developmental psychologist is a master or doctoral degree (PhD) with those holding the doctoral degree more in demand and having the greater range for employment options. The earned income of a developmental psychologist is also highly varied due to area of employment and subtopic of study. Those employed in offices of other  health practitioners earn around $68,400 annually while those employed at Individual and family services earn $57,440 a year (BLS, 2010). A career in developmental psychology allows for diversity among studies and the ability to change topics while still staying in your general field. Another non clinical or therapy related career in the area of psychology is education psychology. Going in this direction involves conducting research on how people learn, and/or designing methods and materials to enhance learning and intellectual, social, and emotional development. This area includes a number of other regions of psychology including developmental, cognitive, and behavioral. Based on the title of this career it is highly possible that an educational psychologist would be working in elementary and secondary schools, along with colleges and universities. Another possible place of employment is with government agencies specializing in education. As an educational psychologist a person could work on curriculum development, incorporationg technology into education, or the studying of gifted learners or those with learning disabilities (Doovis, 2013) The salary earned by educational psychologists was not absolutely defined, however it would have some variation pertaining t o where one was employed. A ccording the Bureau of Labor Statistics general psychologists could earn anywhere between $66,810 and $89,900 depending on who was employed where and experience of each individual (BLS, 2010). Educational psychology would be a good career for individuals interested in the betterment of educational system to produce more productive adults for society, as well as a good place for people who enjoy working with kids through young adults. Psychology degrees contain such a wide area of options for employment that almost anyone could find a job they enjoy with this major. Many of these areas also contain sub level areas for example, a person could possibly be a developmental psychologist working with elderly people on how they learn and obtain information and the connections their brain makes while doing this. Overall, whichever area of psychology one may choose to go into after receiving their psychology degree will provide many benefits to our society whether its improved schools, understanding of mental disorders, understanding of development, or even counseling. The career options are endless. References Beilock, C. L. (2012). Areas of Development in Developmental Psychology. Topics in Cognitive Science, 4, 731-739.

Computer Memory - History, Timeline and More

Drum memory, an early form of computer memory, used the drum as a working part,  with data loaded to the drum. The drum was a metal cylinder coated with a recordable ferromagnetic material. The drum also had a row of read-write heads that wrote and then read the recorded data. Magnetic core memory (ferrite-core memory) is another early form of computer memory. Magnetic ceramic rings called cores, stored information using the polarity of a magnetic field. Semiconductor memory is computer memory we are all familiar with, computer memory on an integrated circuit or chip. Referred to as random-access memory or RAM, it allowed data to be accessed randomly, not just in the sequence it was recorded. Dynamic random access memory (DRAM) is the most common kind of random access memory (RAM) for personal computers. The data the DRAM chip holds have to be periodically refreshed. Static random access memory or SRAM doesnt need to be refreshed. Timeline of Computer Memory 1834 - Charles Babbage begins to build his Analytical Engine, a precursor to the computer. It uses read-only memory in the form of punch cards. 1932 - Gustav Tauschek invents drum memory in Austria. 1936 - Konrad Zuse applies for a patent for his mechanical memory to be used on his computer. This computer memory is based on sliding metal parts. 1939 - Helmut Schreyer invents a prototype memory using neon lamps. 1942 - The Atanasoff-Berry Computer has 60 50-bit words of memory in the form of capacitors mounted on two revolving drums. For secondary memory, it uses punch cards. 1947 - Frederick Viehe of Los Angeles applies for a patent for an invention that uses magnetic core memory. Magnetic drum memory is independently invented by several people: An Wang invented the magnetic pulse controlling device, the principle upon which magnetic core memory is based.Kenneth Olsen invented vital computer components, best known for Magnetic Core Memory Patent No. 3,161,861 and as being the co-founder of Digital Equipment Corporation.Jay Forrester was a pioneer in early digital computer development and invented random-access, coincident-current magnetic storage. 1949 - Jay Forrester conceives the idea of magnetic core memory as it is to become commonly used, with a grid of wires used to address the cores. The first practical form manifests in 1952-53 and renders obsolete previous types of computer memory. 1950 - Ferranti Ltd. completes the first commercial computer with 256 40-bit words of main memory and 16K words of drum memory. Only eight were sold. 1951 - Jay Forrester files a patent for matrix core memory. 1952 - The EDVAC computer is completed with 1024 44-bit words of ultrasonic memory. A core memory module is added to the ENIAC computer. 1955 - An Wang was issued U.S. patent #2,708,722 with 34 claims for magnetic memory core. 1966 - Hewlett-Packard releases their HP2116A real-time computer with 8K of memory. The newly formed Intel starts to sell a semiconductor chip with 2,000 bits of memory. 1968 - USPTO grants patent 3,387,286 to IBMs Robert Dennard for a one-transistor DRAM cell. DRAM stands for Dynamic RAM (Random Access Memory) or Dynamic Random Access Memory. DRAM will become the standard memory chip for personal computers replacing magnetic core memory. 1969 - Intel begins as chip designers and produces a 1 KB RAM chip, the largest memory chip to date. Intel soon switches to being notable designers of computer microprocessors. 1970 - Intel releases the 1103 chip, the first generally available DRAM memory chip. 1971 - Intel releases the 1101 chip, a 256-bit programmable memory, and the 1701 chip, a 256-byte erasable read-only memory (EROM). 1974 - Intel receives a U.S. patent for a memory system for a multichip digital computer. 1975 - Personal consumer computer Altair released, it uses Intels 8-bit 8080 processor and includes 1 KB of memory. Later in the same year, Bob Marsh manufacturers the first Processor Technologys 4 kB memory boards for the Altair. 1984 - Apple Computers releases the Macintosh personal computer. It is the first computer that came with 128KB of memory. The 1 MB memory chip is developed.
