Radio: Early History Presentation Dialogue SOLAR ENERGY. All life on Earth depends on energy from the sun. Solar energy is the source of energy for photosynthesis. It provides the warmth necessary for plants and animals to survive. The heat from the sun causes water on the Earth's surface to evaporate and form clouds that eventually provide fresh rainwater. Solar energy is the result of thermonuclear fusion reactions deep within the sun. These reactions produce so much energy that they keep the surface temperature of the sun at about 10,300B0F (5,700B0C). Even though solar energy is the largest source of energy received by the Earth, its intensity at the Earth's surface is actually very low due to the large distance betwee n the Earth and the sun and the fact that the Earth's atmosphere absorbs and scatters some of the radiation. Even on a clear day with the sun directly overhead, the energy that reaches the Earth's surface is reduced about 30 percent by the atmosphere. When the sun is near the horizon and the sky is overcast, the solar energy at ground level can be negligible. It also varies from one point to another on the Earth's surface. Nevertheless, in the 20th century, the sun's energy has become an increasingly attractive source for small amounts of direct power to meet human needs. A number of devices for collecting solar energy and converting it into electricity have been developed, and solar energy is used in a variety of ways. Solar energy is used to heat houses, and in many countries specially designed solar ovens are used for cooking. The sun also supplies energy to electric generators that provide power for weather and communications satellites and for radio and television equipment. Because the intensity of the sun's radiation at the surface of the Earth is so low, collectors designed to capture solar energy must be large. In the sunniest parts of the continental United States, for example, in orde r for a collector to gather enough energy to serve one person for one day, the area of the collector's surface must be about 430 square feet (40 square meters). The actual energy that can be used depends on the efficiency of the collector and of the device that converts the radiation into usable energy. Flat-plate collectors. The most common flat-plate collectors consist of a dark metal plate, covered with one or two sheets of glass, that absorbs heat. The heat is transferred to air or water, called carrier fluids, that flows past the back of the plate. This heat may be used directly or it may b e transferred to another medium. Flat-plate collectors are used for home and hot-water heating . Flat-plate collectors typically heat carrier fluids to temperatures ranging from 150B0 to 200B0F (66B0 to 93B0C). The efficienc y of such collectors varies from 20 to 80 percent. Concentrating collectors. When higher temperatures are required, a concentrating collector is used. These collectors reflect and concentrate sunlight from a wide area. One such device, called a solar furnace, was installed in the Pyrenees in France and has several acres of mirrors focused on a single target. The energy concentrated at the target is 3,000 times tha t received by any single mirror, and the unit produces temperatures of up to 3,630B0F (2,000B0C). Another structure, the so-called "power tower" plant near Barstow, Calif., generates 10,000 kilowatts of electricity. Here, the furnac e acts as a boiler and generates steam for a steam turbine-electric generator power plant. In sophisticated concentrating collectors such as the California tower, each mirror is rotated by a heliostat that directs the sun's rays fro m the mirror to the target. Positioning motors, drives, and controllers make such systems expensive. Less costly collectors can produce temperatures lowe r than those of more advanced concentrating collectors but higher than those o f flat-plate collectors. For example, parabolic reflectors that concentrate sunlight on black pipes can produce fluid temperatures of about 400B0 to 55 0B0F (200B0 to 290B0C) and can concentrate the solar energy up to 50 times its original strength. Small Stand-Alone DC System The small stand-alone system is an excellent replacement for propane or kerosene lights in a remote cabin, a recreational vehicle or a boat. The size of the photovoltaic (PV) array and battery will depend upon individual requirements. The actual sizing methods are discussed elsewhere. The PV arra y charges the battery during daylight hours and the battery supplies power to the loads as needed. The charge regulator terminates the charging when the battery reaches full charge. The load center may contain meters to monitor system operation and fuses to protect wiring in

The High School Math Courses You Should Take

The High School Math Courses You Should Take SAT / ACT Prep Online Guides and Tips Choosing which math classes to study can be one of the most challenging parts of planning your high school schedule. High schools offer numerous math classes, often at varying degrees of difficulty, and it can be difficult to know which math classes will be the best for you and your future. Read this guide to learn about standard high school math curriculum, AP and IB math courses, which math classes colleges expect you to have taken, and ways to exceed those expectations. Standard High School Math Curriculum Most high schools require students to take three years of math in order to graduate and recommend taking four years. These requirements often also include completing an algebra class and a geometry class. Forty-five stateshave agreed to follow Common Core standards for math, which aim to create a more standardized math curriculum across the country. The Common Core standards state that six content categories should be covered in high school math classes: Algebra Functions Modeling Geometry Statistics Probability However, these standards are very broad and don't specify which math concepts should be taught at which grade, so there is still a lot of differentiation amongschools and amongstates. For high school math,there is not a specific course you should be taking as a freshman, sophomore etc. Instead, there is a series of courses, and each student begins with the math class best suited for him/her, based on testing and prior math knowledge. The typical order of math classes in high school is: Algebra 1 Geometry Algebra 2/Trigonometry Pre-Calculus Calculus However, this order is definitely not set in stone.Some schools teach algebra 1 and 2 back-to-back then move on to geometry, some schools include trigonometry with geometry or pre-calculus instead of algebra 2, and some students take pre-algebra or a similar course if they need to strengthen their math skills before taking algebra 1. However, most high schools follow a course order similar to the one above for their math classes. The math class you take freshman year will be chosen based on your previous math classes and any placement tests you may have taken before starting high school. So, if you already took algebra 1 in 8th grade, you may be able to start with geometry as a freshman and continue down the list from there. Also, not every high school student takes pre-calculus or calculus. What Will You Learn in Your High School Math Classes? While curriculum can vary depending on your teacher, the textbook you use, and the level of your math class, most math classes cover the same main topics. The topics listed below serve as a guideline for the key subjects taught in each math class. Algebra 1:Real numbers; solving, writing, and graphing linear equations; quadratic equations and functions; polynomials Geometry:Plane and solid geometry including constructions, formulas for measurement, and formal proofs Algebra 2:Continuation of the concepts taught in algebra 1, including a more in-depth study of graphing and solving equations, inequalities, and functions Trigonometry:Applies algebra and geometry skills to circular and periodic functions. NOTE: Trigonometry is usually not its own class, but isoften taught during algebra 2, geometry, or pre-calculus Pre-Calculus:Series and sequences, probability, statistics, limits, and derivatives Calculus:Continuation of the concepts taught in pre-calculus, with an emphasis on integration and differentiation You'll be seeing a lot of these images if you study calculus Which Math Classes Will Colleges Expect You to Have Taken? Like high schools, most colleges require applicants to have completed three years of math and recommend four years. Selective colleges often require four years of math, and some schools may also require the completion of particular math classes like algebra 2, geometry, or pre-calculus. For students planning on majoring in humanities, the social sciences, or a similar field, the math classes you took in high school will not be as important to colleges because they'll be looking more at the classes that relate to your intended major. This means you don't have to take the most challenging math classes your high school offers, although colleges want fundamentally talented and well-rounded people, so you should still aim to do well in the math classes you do take in order to maintain a solid GPA. If you plan on majoring in a STEM field (science, technology, engineering, or math), expectations will be higher because math skills will be more critical to your college courses and future career. Most collegeswill require you to have taken four years of math in high school, sometimes including pre-calculus and calculus.You'll be competing for college offers with many other smart STEM people, so you'll want to help yourself stand out by taking rigorous math classes that are offered at a high level. Regardless of what you plan to study in college, it is highly recommended that all high school students complete four years of math because many colleges expect it, even if they don't require it, and it will help you stay prepared for any math classes you may have to take in college. Read on to learn ways to go above and beyond these expectations from colleges. Want to build the best possible college application? We can help.

Everyone should take four years of math in high school How Can You Exceed Expectations? Becausehigh schools offer many math classes at varying levels of depth, speed, and difficulty, the math classes you take and the grades you receive in them will be looked at closely by colleges to help determine your academic ability and how good a fit you would be at the school. If you are not majoring in a STEM field, you do not need to worry as much about exceeding expectations in your math classes; you can focus the majority of your time and energy on classes more closely related to the subject you plan to major in. It's usually enough to take four years of math and get good grades in those classes. If you have the time and ability to take honors or AP math classes, that's great, but it shouldn't come at the expense of your grades for classes more closely related to your major. For students planning to major in a STEM field, you will also want to take four years of math, but you will want to push yourself by taking advanced math classes, studying those classes at honors or AP level if offered by your school, and getting high grades in your math classes. Below are several examples of advanced math classes that will help show a college that you have strong math skills. AP Math Classes There are three AP math classes available: two calculus classes and a statistics class. AP Calculus AB and AP Calculus BC Many students who plan on majoring in a STEM field or who are confident with their math skills take an AP Calculus course. The material that these two classes cover is very similar, but Calculus BC is seen as more difficult because it moves at a faster pace and covers some additional topics such aspolynomial approximations and series, series of constants, and Taylor series. However, both are challenging AP classes, and taking either class is one of the best ways to prove your strong math skills. A solid knowledge of calculus is also required for many STEM careers. AP Statistics This AP course coversexploring data, sampling and experimentation, anticipating patterns, and statistical inference. Statisticsis one of the most widely used math subjects, and many career fields require a background in it. AP Statistics is often seen as not quite as rigorous as an AP Calculus course, but it is still a strong course to have on your transcript. This course is a good option for students who want to take an AP math class but either don't feel ready for calculus or would rather take it in college, or for those who feel statistics will be more useful than calculus for their future career. You can check degree requirements at different colleges for majors you are considering to see which math courses different majors require and to determine whether AP Statistics or AP Calculus would be more useful for you. While it can vary between students, in general, students not planning to major in a STEM field can take either AP Statistics or an AP Calculus course if they choose to take an AP math class. Students who are planning to study a STEM subject should take an AP Calculus course because they will almost certainly need to know calculus for their future classes. They may also consider taking both AP Calculus and AP Statistics if they have room in their schedule. Feeling Lucky? AP Statistics may be the course for you. IB Math Classes In order to obtain the International Baccalaureatediploma, studentsmust take at least one course from each of the six IB subject categories. Math is one of those categories and has four IB options. IB courses are offered at standard level (SL) and high level (HL). The four math classes, from least challenging to most challenging are: Mathematical studies SL Mathematics SL Mathematics HL Further mathematics HL These fourcourses basically cover the same topics, but at different speeds and with different degrees of difficulty. Accordingto the IB website, in these courses students will develop their mathematical knowledge, along with logic and critical thinking skills. The main topics they cover includealgebra, functions and equations, trigonometry, vectors, statistics and probability, and calculus. Similar to AP classes, students majoring in STEM fields should pursue a high level IB math class. More Options for Math Classes If you want to take a specific math class or simply love math and want to take more math classes, there are several options for you. These include both advanced and non-advanced math classes, so they are a possibility for high school students planning to major in any field. Electives Statistics is one of the most common math electives, and it is useful for many career fields. You can take statistics at the AP level (see the above section) or regular level. Other math electives includecomputer math, math literacy, and math applications. These electives often focus on computer skills or practical applications of math. Community College Classes Ifyour school doesn’t offer a specific AP math class or elective, you may be able to take a similar course at a local community college. This is an especially good option for higher-level math classes thatmost high schools don't offer, such as multivariable calculus, abstract algebra, and proof-based math. Because most high school students don't take these classes, completing one can really strengthen your transcript and show colleges you are prepared for future STEM classes. If you're interested in this option, talkto your guidance counselor about how to enroll in one of these courses. It’s becoming more and more common for high school studentsto take community college classes, so the process may not be as difficult as you might think. Do you love math like Isaac Newton did? Consider taking math classes at a community college. Summary Even though most high schools and colleges only require taking three years of math, it is best to complete four years, regardless of what you plan to study in the future, because many colleges expect it, and it will help prepare you for future college classes. The math class you take your freshman year of high school depends on your previous math experience and grades from middle school. You will most likely be required to take a year of geometry and at least one year of algebra while in high school. For students planning on majoring in the humanities or social sciences, meeting the above requirements and getting strong grades in your math classes is sufficient because you should spend the majority of your time on classes more closely related to your future major. If you are planning to major in a STEM field, you need to devote more time and energy to your math classes, so you should take more challenging classes, such as pre-calculus and calculus, and take those classes at an advanced level, if possible.

MHE509 Emergency Planning and Methodology Module 3 Case Essay

MHE509 Emergency Planning and Methodology Module 3 Case - Essay Example This paper will discuss and answer the following question: 4) What are a few of the most important consideration that should be taken into account when evaluating the decision making abilities of the incident Commander Can his decision making abilities be evaluated by a supervisor or other responsible person without the experience from having to perform in similar situations 1. Based on the statements presented above, do you believe that the new Department clearly recognizes the importance of local government in responding to and controlling small to moderate size disasters Please justify your position The US Department of Homeland Security (DHS) employs approximately 180,000 people. It has a daunting mission: lead the nation's unified effort to secure America which encompasses the deterrence and prevention of terrorist attacks and protection from and response to threats and hazards. The department ensures safe and secure borders and promotes the free flow of commerce. (Light, 2007) The DHS clearly recognizes the importance of local government in responding to and controlling small to moderate disasters. The department develops a comprehensive overview of American strategic interests and objectives for the security strategy. It identified the alternatives to implement the national security strategy by defining the security goals for American society, and by describing the internal and external policy instruments required. Furthermore, it identified the sequence of measures needed to respond to external threats. (Parachini, 2003)The DHS works in close coordination with the local go vernment. A clear example of this is that the DHS relies on the first responders such as EMS personnel, public works, fire and rescue and police agencies. Whenever an emergency arises, one of these local agencies is the first to get notified and/or arrive to the scene, and hence, these local agencies are heavily involved. The state homeland security directors' top strategy is to link interoperable communications for first responders. The second strategy is to merge the response strategies of state and local agencies. The third strategy is to develop a state intelligence fusion center where emergency responses can be analyzed and solved. The fourth strategy is to confirm and protect critical infrastructure. The Department of Homeland Security also helps state and local emergency management efforts by providing huge budgets in grants, and program support. A major case is the Emergency Management Performance Grant (EMPG) which is an all-hazards emergency preparedness grant program in s upport of capacity building at the state and local level. The Homeland Security Grant Program

Compare and contrast the possible biological risks and hazards when Essay - 1

Compare and contrast the possible biological risks and hazards when using Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and Ultrasound (US) when imaging a pregnant patient - Essay Example In the process recommendations of how to reduce and ameliorate these risks are critiqued and examined A computed tomography (CT) scan utilises x-rays to provide detailed pictures of structured inside the body of pregnant women (WebMD, 2013). The process is done by getting a pregnant woman to lie on a table that is attached to a CT scanner which is round with an inner-hollow (Romans, 2010; Prokop & Galanski, 2013). The scanner sends x-rays throughout the body and the pictures are studied appropriately (Kalender, 2011). The rotation comes with pictures that are captured and saved on a computer that can be retrieved or printed. CT Scans present more detailed and thorough pictures and images of the area of interest in a medical study or examination (Patient UK, 2014). The system uses conventional radiology and as such, it opens a patient up to the risks of other x-ray systems and processes (DeMaio, 2010; Buzug, 2008). CT Scans opens up a pregnant woman to various risks of radiation during the process, however, the amount of radiation that a pregnant woman will be exposed to varies. Some authorities identify that a patient taking a pregnancy related scan will be exposed to 6.6mSv of radiation which is approximately three years’ worth of background radiation (NHS Choices, 2013). This is obviously very high and could expose a pregnant woman and a foetus to some dangerous levels of radiation. There are various levels of risks that foetuses are directly exposed to during CT scans. The level is examined in a study by Marx et al on the Uterine Radiation Dose (MRAD). The head is exposed to under 50 MRAD, the Thorax is exposed to 10-590 MRADs, the Abdomen, 2800 – 4,600 MRADs whilst the Pelvis is exposed to 1,940-5,000 MRADs (Marx, Lockberger, Walls, & Adams, 2013). However, the inherent benefit is that it is quick and accurate and it is often the best way to check a patient

Introduction to Indigenous Australia Essay Example | Topics and Well Written Essays - 2500 words

Introduction to Indigenous Australia - Essay Example The indigenous land rights have gain support from article 1 of the International Bill of Rights. This is the right of people to control their resources and wealth, self determination and maintain their ways of subsistence (Mugambwa, 2003). The Aboriginal land rights movement started out of the equal citizenships and civil rights campaigns, starting from 1920s to 1960s. As the community’s control grew in these civil rights organizations, the fight for the return of the stolen Aboriginal land took a pivotal role in 1960s and early 1970. There were a number of campaigns that shook the Australian community and led to a variety of major developments in the policy. However, funding dependency and the bureaucratization of the Aboriginal services delayed these campaigns early in the 1980s (Edwards, 2001). Australian Aborigines Progressive Association (AAPA) became founded in 1927 by Maynard and Lacey. This was Aboriginal first political party and its formation got stimulated by the re duction in the Aboriginal reserve land, dictatorial practices of Aborigines Board of Protection and a rise in the kidnappings of kids. Maynard declared that the original land owners were the Aboriginal and their rights are above all others. The party has often been regarded as a Christian organization by the Non Aboriginal Australians because of its motto, â€Å"One God, One Aim, and One Destiny† (Lee, 2006). It took about 10 years for success in the campaigns of changing Australian constitution. A referendum became passed in 1967 with more than a 90 percent vote count and became a successful exercise in public education about the Aboriginal, civil rights. The referendum was, however, not about the right to vote, as it became believed, but rather to allow the federal government to provide services and legislate for the Aboriginal people. The federal government power over the states is still a serious issue in the politics of Australia (Edwards, 2001). Meanwhile, a number of t he Aboriginal peoples at Yirkalla, in 1963, gave the Federal Parliament a petition complaining the excision of most of their land to one of the mining companies. They claimed that the land got to be used by the Yirkalla communities for hunting and gathering since time immemorial. The same resistance was also growing in Cape York, a place where the Aurukun and the Mapoon peoples got evicted by the federal government from their land. This was in order to pave the way for aluminum companies. Victoria in 1960 had witnessed a dispute over arranged Lake Tyers closure, under the assimilation policy (Lee, 2006). Laurie Moffat and Doug Nicholls joined the Lake Tyers elders to fight for the community control over the mission. The Victorian government in 1970 handed the Aboriginal people a freehold title to the reserve. Charles Perkins, In 1965 led students in freedom rides around the country, fighting apartheid ways in swimming pools, bars and theatres. In 1966, the people of Gurindji moved o ff the Wave Hill Station over a claim for equal and fair wages from their pastoral company employer, which later turn into a claim for the return of their ancestral land. The Gurindijis gained support both from the Aboriginal and the non Aboriginal organizations, which contributed to the 1960s equal pay cases. The Gurindji claim became partly met 10 years later when the Labor Government gave back some parts of their land. The Larrakia claim

Can Experts Disagree on the Same Facts?

Can Experts Disagree on the Same Facts? Prescribed Title 5: Given access to the same facts, how is it possible that there can be disagreement between experts in a discipline? Develop your answer with reference to two areas of knowledge. For centuries scientists and historians alike have debated topics within their field of study. Whether it be the structure of an atom or the cause of the fall of the Roman Empire, experts in these fields often disagree despite having access to the same exact facts and information. These separate interpretations of data leads to the question of how it is possible that the same facts do not always point to the same general truths. Although experts in the fields of science and history have access to the same facts, the experts who analyze and interpret these facts are human beings, whose thoughts are impacted by the different cultures, experiences, and perspectives in which they were raised. One important question that needs to be raised is what makes someone an expert? Better yet, what is a fact? An expert is someone who has an extensive background in a certain subject and is recognized by others as having a comprehensive understanding of a specific topic. This means that they have a great understanding of the subject matter of which they are an expert, and others can attest to this proficiency. Facts are known truths that are commonly accepted and verifiable. A fact must be verifiable in order to be legitimate. Understanding these terms allows us to truly understand the nature of historians and scientists and their interpretations of information. One of the most important, yet most debatable, tasks that a historian must complete is weighing evidence after reviewing historical facts. Historians make decisions based on many different pieces of evidence. They decide how important each piece of evidence is to the way that history played out. This brings up the question of the extent to which the weighing of evidence by historians in relation to events in history is subjective or objective. The weighing of evidence tends to be subjective simply because of the often multiple different causes of certain events in history. This can be seen in the analysis of almost every historical event in recorded history, but especially in the analysis of the cause of World War II. Many different factors played into the cause of World War II. Between the economic sanctions imposed by countries such as the United States and Great Britain, political tension between the major powers, or expansionist foreign policies of Italy, Germany, and Japan, no single cause can be seen as the only one to start to war (History.com staff). However, deciding which cause had the greatest impact on war is what historians debate over and weigh evidence over, yet they often come to separate conclusions. The different cultures, experiences, and perspectives of the historians leads to their different interpretations and evaluations of evidence in history. Although these experts analyze the same data, the lenses through which they view the evidence are different. Historians do their best to analyze facts and their impact on history with total objectivity, yet the nature of the weighing of evidence is very subjective. Historians have to use their own personal values and emotions, based on their own personal culture and experiences, in order to evaluate evidence and make decisions based on these evaluations. This also brings up the question of the extent to which the upbringings of a historian has an impact on their analysis of historical facts. All historians grow up in unique situations and so their view on the world and the way humans interact with each other is slightly different. Furthermore, their opinions on the interactions of foreign powers can often be impacted by their nationalities and the education they received. This personal opinion is most prominently seen with debate over differing political ideologies and their impact on foreign nations. I saw this debate first hand in my history class. The topic of the discussion was Cuba and the rise of Castro as a communist dictator. As the child of a Cuban exile, I have heard anecdotes from people who lived and suffered under the dictatorship of Fidel Castro. My family has seen the thousands of people who were killed under his command and the conditions of the Cuban people because of his policies. Undoubtedly, because of my personal upbringings, I am biased against Castro and communism in general. This extremely negative experience with communism has swayed my opinion about the political ideology to a great extent. However, in class, my history teacher argued that Fidel Castro had a great, positive impact on Cuba and the Cuban people. My teacher claimed that Castro reduced the unemployment rate and generally improved the average living conditions of the Cuban people. Just like historians, both my teacher and I were analyzing the same facts about the same country, yet were drawing drastically different conclusions. We were weighing evidence based on our own personal cultures and beliefs and drawing conclusions about the general nature of the regime. This personal example gives insight to the debates that historians go through in order to come to conclusions about events or topics in history. Historians attempt to decipher data in an objective way, yet the weighing of evidence is subjective and easily influenced by the culture of the historian. In this way, historians rarely come to the same conclusions based on the same facts simply because each individual historian is weighing evidence based on their own unique personal experiences. These experiences and aspects of their culture give each historian a predisposed idea about topics in history that causes them to evaluate events in history in different ways. In the field of science, the different types of data often leads to disagreement and separate conclusions based on this data. In science, the two main types of data are quantitative and qualitative; quantitative data being data that can be measured in numbers while qualitative data being data that can be observed and described. Quantitative data tends to not only be more precise, but also easier to reproduce. On the other hand, qualitative data is measured based on the scientists interpretations of a certain quality within an experiment. For example, when performing titrations, scientists often use color indicators to show when the titration is complete. However, they must decide for their own when the color has changed sufficiently for the titration to be considered complete. This leads to a large amount of room for error. This same experiment can be performed around the world several times by experts in the field of science yet they may all come to different conclusions about the d ata. This imprecision of this data leads to the question of the extent to which the preconceived ideas of scientists affects the way they interpret data. Often times in science, data is either difficult to describe, as in the exact color of a solution when a titration is complete, or in instances where an experiment cannot be conducted in order to test a theory. For example, String Theory was proposed by scientists years ago and many scientists continue to support it today. In the words of Richard Dawid, On one side of the divide stand most of those physicists who work on string physics and in fields like inflationary cosmology or high energy particle physics model building, which are strongly influenced by string physics. Yet, many other experts disagree and refuse to support the theory. They, consider string theory a vastly overrated speculation, and without being able to conduct an experiment to prove the theory, it is not valid. They refuse to consider the evidence proposed by scienti sts who support the theory simply based on this single idea. The nature of a scientists research can help explain why many scientists can come to different conclusions when analyzing the same data. When a scientist sets out to conduct an experiment, they often have a goal in mind. Whether they are trying to prove a theory correct or make a new discovery, scientists often have preconceived ideas about the topic of which their experiment is concerned. In other cases, scientists are being supported financially by investors who are looking for the scientists to come to certain conclusions, especially in relation to medicines where investors are looking to create a new drug in order to make a profit. Because of this, scientists often have biases when conducting experiments. This leads to them analyzing data in a way that will support their goals. They will often disregard or assign insignificant value data that contradicts the claim they are trying to support. This is generally the source of disagreement between scientists when analyzing the same d ata. Every day, historians and scientists alike are analyzing undisputable facts. They look at these facts and come to completely separate conclusions. As human beings, we all are subject to interpreting facts through the subjective lenses of our cultures and personal experiences. Although experts in both the fields of history and science may try to be objective as possible, certain elements of research in these fields require subjective analysis that can vary from expert to expert. This gives way to differing conclusions among experts in the fields of science and history and, in general, disagreements between experts in a certain field despite having access to the same facts.

Problems of Conducting Research Into the Causes of Stress Essay

One problem when conducting research into the causes of stress is the generalisation of the sample, if the sample is restricted; this has limitations in terms of generalising the results to the total population. In the study by Johansson, a sample of only 24 workers was used and from a specific job type. This sample is unreflective of all job types and is too small to be applicable to the general population. Conclusions made may only be relevant to this sample. However it could be argued that the factors that cause stress in jobs such as deadlines and the dependence of others on you are common in all types of jobs and therefore using a sample of the specific job type becomes less restricted and applicable to other people in jobs with common stressors. A second problem when conducting research into causes of stress is the validity of measurements. Validity refers to whether the results measure what they are supposed to measure and this is often affected by the research method. The self report method is often questioned in terms of validity as participants have the ability to give socially desirable answers and steer away from the truth. In the study by Kanner, questionnaires were posted out to participants and a Hassles and uplifts scale was asked to be completed every month for 9 months and the Berkman life events scale after 10 months. This study, due to the use of self report lacks in validity, as researches are unsure as to whether data obtained reflects the true opinions of participants, which is an issue when trying to apply to everyday life. However the self report method is useful, despite it lacking in validity. It gives participants the freedom to write about their own subjective feelings and due to stress being individually perceived differently, it is useful in tailoring treatment to individuals to meet their needs. A third problem is reductionism, studies often reduce many factors that cause an individual stress to one factor, such as in the case of Johansson study, it was concluded work was the source of stress. However individual factors such as personality could play a role, researchers do not know that stress prone individuals are more likely to be in a high risk job. By failing to take into account other factors, resources and time may be used in the wrong area.

The eNotes Blog 3 Important Ways to Brighten the Future of Reading in theU.S.

3  Important  Ways to Brighten the Future of Reading in theU.S. Reading a great book for pleasure can be a magical experience for kids. It takes them to new places, lets them relive history, and teaches them about worlds they would never encounter in real life. Unfortunately, a study on the state of reading in the United States has recently revealed some disheartening statistics: did you know 66 percent of 8th graders tested below proficient in reading, according to The Nation’s Report Card? The problem: reading is one of the most important skills for a child to have- it will follow them through the rest of their schooling and career, in every way. Luckily, as an educator, you have the power to change these statistics, teaching your students a love of reading that will carry through their entire lives. 83% of kids say they love when parents read a loud to them. In our online world, books are collecting a thick layer of dust, including those in your students’ houses. Start a reading incentive program for students and their parents- the student that reads the most at home each month gets to choose a free book of their choice. Reading together as a family not only helps students build their own love of reading while developing important reading skills, but it also helps to establish a bond between parent and child. The average child spends 7 hours a day in front of a screen. EdTech is the new normal for teachers- and for a good reason. Technology helps you engage students and reach those who are struggling. However, reducing the amount of screen time in the classroom, even once a week, will motivate students to sit down with a book. Not to mention, limiting screen time can have a variety of other non-reading benefits- children who spend more time in front of a screen have more behavioral problems, sleep disorders, and higher rates of obesity. Encourage students to use technology to find the books they want to read- looking up titles on the library’s website- and then sit down in the classroom library to read it. Encourage parents to limit screen time by swapping a TV night for a family book night, where the TV stays off and everyone grabs their favorite book to settle in for a night of reading great stories. You could do this independently or read aloud together as a family. 52% of students love class reading time; only 17% of teachers do this. The best part about this statistic is that kids want to read more in the classroom, independently and as a group. Despite the focus on testing and teaching to the test, there are many ways to build more reading time into the school day. For example: Encourage more students to read aloud  during lessons. Give students 30-minutes of silent reading time once a week. Build reading into other lessons- reading non-fiction books is a great way to explore history, science and geography topics. Assign a weekly current event, requiring each student to read one non-fiction article at least once a week. If you or your school can’t afford more reading materials for the classroom, buy discounted books and magazines when there are small budget openings- the more there is to read, the more likely students are to do it. Reading is one of the most important skills a student can have, and you are in a powerful position to make a change for the better. Consider how you can make a difference in your classroom and motivate parents to do the same at home. This is a guest post from contributing writer, Jessica Thiefels.  Jessica Thiefels is the editor of Whooo’s Reading and an education blogger, who’s been featured in publications such as EdTech Digest and Daily Genius. Her favorite books growing up were My Side of the Mountain and The Giver, and she hopes to inspire a similar love of reading in students and educators.

However, as the Catholic Church became increasingly unsatisfied with the mannerists work as it no longer honoured the spirituality the Church required. Therefore a new form of art was created Baroque A style of which Ruben was renowned for due to fact that he fundamentally revitalized and redirected Northern European painting as Renaissance art gradually began to lose popularity with secular authorities, yet kept its freedom and classical themes. The Renaissance was a period of great creative inspiration, from which many artists used as a motive to move away from the restrictive methods of Byzantine - a style that framed itself primarily upon the glorification of God. Throughout the 15th century artists studied the natural world, perfecting their understanding of such subjects as anatomy and perspective. The High Renaissance was of the great explosions of creative genius in history, and produced many masterpieces still thought of as irreplaceable to date. Despite this, Rubens was one of the earlier Baroque artists who realised the intricate and over-complicated style of mannerism and late Renaissance work would not achieve any strong emotive outcome. Rubens, raised initially as a Calvinist, taught by humanist scholars and finally re-baptised into Roman Catholicism was inevitably to become an artists who devoted much of his talent into the glorification of religion, which was ...

Many rescue groups and city shelters tend to spend a great deal of money on aspects such as regular visits to the veterinarian, boarding costs, and grooming. Many people also do not realize that adopting a pet leaves them with many options in regards generating support groups that help them to live in harmony with their new pet.
