Healthcare industry Essays Healthcare industry Paper Healthcare industry Paper Medicare and Medicaid are health insurance programs that are administered by   Ã‚  the U.S. Department of Health and Human Services (CMS-HHS, 2007).   There are basic differences between the two health insurance programs.   Medicare is designed to provide health support services to individuals at least 65 years old and older, to individuals below 65 years of age but have particular disability, and to individuals of any age who have end-stage kidney diseases. On the other hand, Medicaid is designed to provide health support services to individuals who receive a particularly low income.   Federal and state legislations have been created as a guide to determine which individuals and families are eligible for inclusion into this health insurance program.   The eligibility criteria for Medicaid are different for each state of the United States. The health coverage of Medicare is comprised of 3 parts (Cook et al., 2007).   Part A provides hospital coverage which includes hospital and nursing or hospice facilities.   Part B provides coverage for the professional fees of physicians as well as outpatient care.   Prescription drugs are another component supported by Medicare, which significantly reduces the cost of pharmaceutical drugs and regulates prescription drug rates from increasing.   Medicaid, on the other hand, follows Title XIX of the Social Security Act, which states the medical assistance should be offered for particular basic services to the most deprived individuals in the United States. These basic services include in- and outpatient hospital services, prenatal care, vaccinations for children, laboratory tests and nursing services.   Other states, depending on the federal funds provided, may also offer other services such as diagnostic tests, prescription drugs and rehabilitation services.   Hence the services of Medicaid are not as freely accessible as that provided by Medicare. Another difference between Medicare and Medicaid concerns the monthly payments for the health insurance program.   In the case of Medicare, members have to pay premium for at least Part B which is the medical insurance.   The premium is approximately $78.20 per month, covering the physician services and outpatient care.   Majority of the members of Medicare do not pay the premium for Part A or the hospital insurance because they already pay for Medicare taxes when they were still working (West and Weeks, 2007). In the case of Medicaid, there is a very minimal premium that has to be paid for by the individual, but there is a rigorous criterion during the application process for Medicaid.   It is known that individuals who receive Medicaid assistance are the poorest people in the United States hence there is no need to pay a monthly premium.   One of the major requirements for Medicaid is that the individual falls below 133% of the federal poverty line, hence not all poor individuals can avail of the Medicaid support services. There are three components associated with the eligibility for reimbursement.   Firstly, the individual must have substantial proof that he receives a low income.   Secondly, the individual should be able to show that his assets and resources are below substantial levels. This will consider whether the individual receives any financial assistance from the Temporary Assistance for Needy Families (TANF) or the Supplemental Security Income (SSI) programs.   Thirdly, the individual will only be able to get a reimbursement is he is able to show that he is experiencing excessive medical expenses.

Bachelors Degree How Many Years Does It Take

Bachelor's Degree How Many Years Does It Take SAT / ACT Prep Online Guides and Tips Wait- a bachelor’s degree is how many years? Most Americans wouldn’t hesitate to say, "Four." But as it turns out, this isn’t always the case- and certainly doesn’t have to be for you if you’d rather graduate early! In this guide, we addressone of students' biggest questionsabout college: how many years is a bachelor’s degree, and how can you shorten this time frame? Read on to learn what a typical bachelor's degree entails in terms of credits and classes, how long bachelor's programs generally are, and how you can reduce the time it will take you to earn a bachelor's degree. We'll also cover the biggest drawbacks of getting your degree in less than four years. What Is a Bachelor’s Degree? Overview A bachelor’s degree- also known as a baccalaureate- is an undergraduate degree bestowed by colleges and universities onpeople who have completed an academic program, typically lasting around four years. A bachelor’s degree designates achievement of an education level higher than that of a high school diploma/GED and associate degree (i.e., a two-year undergraduate degree) but lower than that of a graduate degree (master's or doctoral). One of the most common types of degrees for college-bound students, bachelor's degrees are available in a vast array of disciplines, from math and science to the arts and humanities. They also come in several varieties depending on the discipline/field, program, and institution. Here are some of the most common types of bachelor's degrees you’ll see: Bachelor of Arts (BA) Bachelor of Science (BS) Bachelor of Fine Arts (BFA) Bachelor of Business Administration (BBA) Bachelor of Music (BM) Bachelor of Architecture (BArch) Bachelor of Engineering (BE, BEng) There are many benefits to getting a bachelor's degree. Besides expanding your knowledge of a particular field, bachelor's degrees aregreatfor finding well-paying jobs and establishing a career that interests you. According to findings by the US Bureau of Labor Statistics, the median weekly earnings for people with a bachelor's degree is $1,173 per week. That's $337 more than what those with associate degrees make in a week,and $461 more than what those with only high school diplomas make. In short, education pays off! Now that we’ve looked at what a bachelor's degree is and how it can be useful for you, it’s time to get to the meat of the article: how many years is a bachelor's degree? Getting a Bachelor's Degree: How Many Years Does It Take? How long does it take to get a bachelor’s degree? The answer to this question depends on several factors, but in the US, most students earn their bachelor's degreesin four to six years of full-time study (not including summers). According to a 2016 report by the National Student Clearinghouse Research Center, 37.5% of students in bachelor's degree programs at four-year public institutions earned their degrees in four years. In addition,75.4% of students earned their bachelor's degrees in six or fewer years. Of course, some students earn their bachelor's degrees in less time- as little as three years- whereas others earn theirs in more time- up to eight or more years. Here are some key factors that determine how much time your bachelor's degree takes: Whether you have any credits from AP/IB exams or community college classes How many classes you take per semester Whether you take classes over the summer What your major requires in terms of credits and classes Whether you’re double majoring Whether you’re taking classes full- or part-time The total number of credits youmust accumulate to get your bachelor’s degree can vary slightly depending on the school and whether it uses a semester or quarter system. Generally speaking, most bachelor's degree programs require a minimum of 120-130 semester credits, or 180-190 quarter credits. This is roughly equivalent to 40 classes. The classes you must take will vary widely depending on both your major and school. Typically, though, you’ll need to take the following types of classes to get a bachelor's degree: General Education classes:Normally, all bachelor's degree candidates must take these core classes, regardless of their majors. Classes span a variety of subjects, including math, science, writing, and social studies/history. Exact requirements vary depending on the school. Major classes: These are the classes you must take to fulfill the requirements for your major and minor. Usually, these may not overlap with the Gen Ed classes you're required to take. College, school, or departmental classes: These classes are required by the college, school, and/or department that houses your major. At the University of Michigan, for instance, those in the College of Literature, Science, and the Arts must earn at least 100 credits in the College but may earn the remaining 20 credits through a different college or department, such as the College of Engineering. When it comes to taking electives- even if the credits count toward your degree's total number of required credits- if they do not fulfill any of the three criteria above, they might prolong the time it takes for you to earn your bachelor's degree. Lastly, many colleges these days offer online bachelor's degree programs,through which you can earn a bachelor’s degree entirely online. Because these programs offer more flexibility than a traditional program, you could earn your degree in even less time (more on this later). Ready to speed through your degree? How to Get a Bachelor’s Degree in Less Time: 6 Tips How many years is a bachelor’s degree? Typically four, but it’s certainly possible to get yours in less time, if you so choose. In this section, we go over six key ways you can reduce the time it’ll take to get your bachelor’s degree. Tip 1: Start Earning College Credit in High School One of the easiest ways to reduce the time it takes to get a bachelor's degree is to start in high school by taking AP tests, IB tests, and community college classes. First, let's look at AP tests. Byearning high scores on AP exams (typically a score of 3+), you'll getcollege credits that can be applied toward your bachelor’s degree. For example, at the University of Michigan you can earn anywhere from 2 to 5 credit hours for high scores on AP tests (what you earn will vary depending on what exam you take and what score you get on it), whereas at Stanford you can earn up to 10 quarter units for scores of 4 or 5 on AP tests. AP scores can also allow you towaive certain General Education or major requirements at colleges, thereby saving you time you would've spent actually taking those classes in college. Nevertheless, not all collegespermit this. Some will only accept AP credits as elective credits that count toward the total credits required for your degree but not for specific major/minor or departmental credits. For example, on its website,UCLAmakes it clear that "AP credit does not satisfy General Education requirements." In addition to AP scores, high scores from IB exams can count as credits toward your bachelor’s degree. You’lltypicallyneed a score in the range of 5-7 on an IB exam in order to earn college credit for it. Be aware that colleges are more likely to award credit for higher-level IB exams than they are standard-level IB exams. So if you’ve finished a standard-level IB course, just know that you might not actually get any college credit for it! In addition, becauseAP classes and tests are more popular, colleges might be less likely to accept IB exam credits. I strongly advise you to check the official credit policies for each college you're consideringso you'll know what kinds of tests they accept for credit and how much credit you’ll get (some schools offer more credit for AP tests over IB tests, or vice versa). Finally, and only if a collegeallows this,you might be able toearn credits for college while in high school by taking some community college courses.It's not particularly common for four-year colleges to accept community college credits from high school students, so be sure to check first with the colleges you’reconsidering to see whether they'll actually accept these credits. Tip 2: Choose a Major Early and Stick With It Knowing for sure what you want to major in will help streamline your bachelor's programand could even cut down the time it takes you to get your degree. If you end up changing your major a couple of years in or wait to declare one until late into your program, you’ll most likely be in college for at least four years- possibly longer! Moreover,choosing just one major can reduce the time it takes to get your degree.Though there’s nothing wrong with double majoring(I did it), doing so means you’ll likely be in school for four years, maybe longer. Ultimately, you have to decide what’s important for you.Would you rather get your bachelor’s degree in less time but only be able to have just one major? Or, would you rather spend more time in college- four or more years- and be able to study everything you want? I suggest meeting with your college academic advisor as soon as you can to explain your plans and see what your options are for courses and schedules. Talk to your advisor aboutadjusting your schedule so you can graduate sooner. Tip 3: Take More Classes Each Semester/Quarter One way students can try to reduce the time to their degrees is to take more classes during the semester/quarter. Essentially, instead of taking the normal course load of, say, four classes per semester (whichwe'll sayis equal to 16 credits), you'd be taking five classes (20 credits). By taking just one or two extra classes a semester, you could cut down your program by as much as a whole semester or year, allowing you to graduate early. As a reminder, the "normal" number of credits you take per semester/quarter will vary depending on the institution. Check with your college (or any colleges you’re considering) to see how many credits students typically take and whether there is a maximum number of credits or courses you can take per semester/quarter. Tip 4: Enroll in Summer Classes Manystudents earn their bachelor's degrees in four years of continuous full-time study, but this time frame doesn’t include summer courses, which offer you an extra quarter or semester of credits.Just makesure that the courses you take are ones you need to graduate, such as major courses or General Education courses, and you're ready to go. Though most students who take summer classes do so at their home institutions, another option is to take college classes at a local community college during the summer. Doing this can be more convenient if yourschool is far away and you want to stay close to home in the summer. Check that your school will accept these summer credits before you decide to enroll in any community college classes. Also, be aware that you most likely won’t be able to transfer grades to your home institution- just the credits you earn. Summer school students need cool backpacks, too. (CollegeDegrees360/Flickr) Tip 5: Look Specifically for Shorter Bachelor’s Programs Many schools offer bachelor’s degree programs that are specifically designed to let you getyour degree in a shorter time frame, usually three years. These programs can vary significantly in how they’re structured, butnormally you'll be given a strict schedule to follow as well as special academic advising. If you’re dead-set on getting your degree in less time, it's worthit to see what colleges offer these programs and whether they have the program available in your intended major.

An online programis where you take all your classes and turn in all assignments online. A hybrid program, on the other hand, is where you take both in-person and online classes- in short, it's a mix between a traditional program and an online one. If you don’t mind the idea of not going to an actual campus and not meeting with classmates and professors, an online or hybrid bachelor’s degree program could be for you. Just know that there can be some big disadvantages to doing one, including fewer (if any) networking opportunities and a lack of prestige (online and hybrid programs are still sometimes viewed as less "legitimate" than traditional ones). These programs can save you both time and money becauseof their flexibility. For example, at Purdue, "most [online] bachelor’s degree programs can typically be completed in 2 to 4 years." This short time frame is made possible due to the great flexibility students have regarding when they choose totake classes and access assignments. Here's a list of the top 15 universities offering online bachelor’s degree programs. (Note that the US News rankings are specifically for the online programs and not for each school as a whole.)

Perhaps you’re hoping it’s less than four for you- and while there’s nothing wrong withearning your degree faster, there are some drawbacks you should be aware of. #1: Your Workload Will Be Heavier Finishing a bachelor’s degree in fewer than four years most likely means you’ll be working harder than other students by taking more classes during the school year and/or over the summer. With such a heavy workload, you’ll more than likely havefar less time to interact socially, go on vacations, and participate in extracurricular activities,such as clubs and sports. This could all negatively impact your personal satisfaction with your college experience, depending on what you hoped to get out of it. For some students, these drawbacks might not bea big deal.But if they will be for you, you might want to reconsider what you’re willing to give up in order to get your degree faster. #2: You’ll Have Fewer Chances to Take Classes Just for Fun Getting a bachelor’s degree in less time means not only following a strict schedule but also taking only the classes you need to take to get your degree. Consequently, you’ll very likely have fewer opportunities to take electives, that is, classes that are just for fun. Electives can enrich your college experience by allowing you to explore subjects you’re interested in but have never had the chance to study in-depth. Without the time in your schedule to take any classes for fun, you might feel as though you've missed the chance to explore other intellectual interests you have outside your major. #3: You Won’t Have Time for Summer Jobs and Internships Similar to the disadvantage above, if you’re taking classes over the summer to get your bachelor’s degree in less time, you won’t have any time during the summer to focus on other things, such as internships and jobs. This can be a big drawback if you’re hoping to get some work experience in your field before you graduate college. The trade-off here is whether you would rather graduate early with little to no work or internship experienceor graduate at a normal (or slightly slower) pace with more professional experience. #4: You’ll Have to Pay More Upfront Taking extra classes- whether it’s during the school year, the summer, or both periods- usually means you’ll need to pay more upfront for these classes. Although finishing your bachelor’s degree in less time can save you a ton of money in the long run (you won’t have to pay for any more tuition, class fees, housing, or meal plans) you still need to be prepared to pay more upfront for the extra classes you'll be taking and any housing and/or meal plans you’ll need(if taking summer classes). Recap: So A Bachelor’s Degree Is How Many Years? Most students in the US earn their bachelor’s degrees in about four years of continuous full-time study (excluding summers). That being said, many people are able to shorten this time frame to as few as three or even two years by planning ahead and taking advantage of certain opportunities. Although you’ll still need the minimum number of credits required to get your bachelor’s degree (usually 120-130 semester credits or 180-190 quarter credits), it ispossible toaccumulate this number of credits in a shorter amount of time. Here are six possible ways you could do this: Start earning college credit in high school through AP exams, IB exams, and (if a college will accept it) community college courses Choose a major early on and stick with it- this will help you plan out your future better and keep you on track with one main academic focus Take more classes each semester/quarter so you can earn the credits you need faster Enroll in summer classesto earn credits ahead of schedule Look specifically for shorter bachelor’s programs if you prefer a program that offers a built-in structure for studentswho want to finish in a shorter time frame Consider getting a bachelor’s degree online- bothonline and hybrid programs will give you the flexibilityyou need toeasily earn a degree in less time Before you get to work figuring out how you can shorten the time it’ll take to get your bachelor’s degree, takea moment toconsider some of the drawbacks tofollowing such a strict schedule. Here are the four biggest disadvantages you’ll want to think about before making any decisions: Your workload will be heavier, making it hard to find time for socializing with classmates and friends, participating in extracurricular activities, relaxing, andgoing on vacations You’ll have fewer chances to take classes just for fun, which can be frustrating if there are fields outside your major you’re interested in learning about You won’t have time for summer jobs or internships,meaning you’ll be graduating with less professional experience than you might want to have You’ll have to pay more upfront for extra classes, summer housing, and meal plans- though you'll most likelysave money in the long run!

European Union Law - Institutional Balance Essay

European Union Law - Institutional Balance - Essay Example Initially, the crusade was focused on centralizing the coal and steel industries of Europe for better control and protection. It was thus evident at the start that the reason for the amalgamation was economics which explains why the group was earlier created as the European Economic Community.1 Since the interrelations and interactions among the members of the community were embodied in treaties or equivalent covenants, there was a need for an adjudicatory body to ensure that the provisions and terms of those agreements between and among independent territories or jurisdictions were religiously kept and to see to it that the institutions and agencies under the Union formulate and execute acts and deeds which are legally in pursuance of those treaties and covenants. This led to the establishment of the Court of Justice of the European Union in the year 1952. The tribunal is now one of the seven pillars of the European Union and its judicial authority cooperating with the courts of the member states.2 The coordination includes matters of interpretation of the relevant laws and rules. The most important sources of law are legislation and jurisprudence, also called case law or common law. In the case of the European Union, it key institutions have legislative powers. ... even without these law-making bodies, there are already several treaties between and among member states which have been in force and effect and which necessarily become components of European Union Law. Most of these legal agreements are now incorporated in the European Union Consolidated Versions of the Treaty on European Union and of the Treaty Establish the European Community. The European Council Treaty and Protocols which was amended by the Treaties: Merger Treaty, the several Acts of Accession, the Budgetary Treaties and others also form part of the European Union Law. Secondary legislations in the nature of regulations, directives and decisions issued and adopted by the European Council, as well as international agreements for and in behalf of the Union, are also included in the whole legal framework. It is worth to note that the European Council, known today as the Council of the European Union, is composed of the representatives of the Member States who hold ministerial lev el positions. While there is only one Council, it is not a fixed institution and its designation and membership depend on the subject matter then at hand. Hence, if the issue then prevailing is about agriculture, the respective agriculture ministers will be the participants and the body will then be called the Agricultural Council.3 There can therefore also be a Council of Foreign Affairs, or of Finance, or of Home Affairs, etc. It is likewise important to observe that institutional balance is of fundamental significance in the political sphere of the European Union. No less than the key institutions of the union zealously advocate this kind of neutralization in order to conserve and maintain order, working harmony and decorum among all the branches and instrumentalities of the

Aircraft emergency response Essay Example | Topics and Well Written Essays - 2500 words

Aircraft emergency response - Essay Example The planning processes should be interlinked to ensure that the company is able to take appropriate initial actions, and then continue managing the emergency crisis for an unspecified duration. Ultimately, the aim of comprehensive emergency response and crisis management planning is to minimize pain and suffering of all associated in the event of an accident in the airport premises or its immediate vicinity and to save human lives All airports authorities should have aircraft rescue and fire-fighting services and equipment, for procedures for handling aircraft fire emergencies, and for specialized vehicles used to perform these functions at airports, with particular emphasis on saving lives and reducing injuries coincident with aircraft fires following impact or aircraft ground fires. Everything that can be done to protect the health and life of the individual must have priority over maintaining aircraft equipment and facilities, however valuable these may be. Human life comes first; efforts to salvage aircraft, buildings or technical equipment are secondary. "If you are looking for perfect safety, you will do well to sit on a fence and watch the birds; but if you really wish to learn, you must mount a machine and become acquainted with its tricks by actual trial." Emergency response is a product of preparedness. ... Especially the first responders: fire, police, emergency medical service, and building safety professionals. Major accidents are being studied by many emergency response agencies to achieve workable response procedures using a specific set of guidelines applicable to each type of occurrence. As in nearly all countries, the guidelines and recommendations set out in Annex 14 of the International Civil Aviation Organization (ICAO) applies to fire fighting and rescue services. Planning for the crisis is the key to minimizing the harmful effects of aircraft accident. Every airport is categorized for rescue and fire safety purposes in accordance with International Civil Aviation Organization (ICAO) guidelines, depending on the maximum total length and fuselage width of the aircraft normally used at the airport. Some of the regulatory requirements for international airport authorities and covered by the existing regulations include (Shantakumar 29): 1. The minimum number of vehicles and quantities of extinguishing agents, emergency equipment and the qualifications and training of personnel that must be made available by the airport operator; Aircraft emergency response 4 2. A three-minute response time for first-response vehicle(s) responding to an emergency at applicable airports; 3. A minimum of 90 per cent coverage of commercial aircraft conducting regular flights, and in addition, coverage of 100 per cent of all 20-passenger aircraft. 4. The presence of qualified personnel, trained who are able to deliver aircraft rescue and firefighting service at the airport during operating hours; 5. The annual testing of emergency services conducted, monitored and enforced to evaluate response times and confirm that the emergency services being

Anatomy & Physiology Essay Example for Free

Anatomy Physiology Essay In this assignment the concept of homeostasis will be explained and the probable homeostatic responses to changes in the internal environment during exercise will be discussed. Homeostasis is simply how the body keeps conditions inside the same. It is described as the maintenance of a constant internal environment. Generally, the body is in homeostasis when its needs are met and it’s functioning properly. Every organ in the body contributes to homeostasis. A complex set of chemical, thermal, and neural factors interact in complex ways, both helping the body while it works to maintain homeostasis. In homeostasis there is the concept of Negative feedback which ensures that, in any control system, changes are reversed and returned back to the set level. There are four different homeostatic mechanisms for regulation these four are the heart rate, breathing rate, body temperature and blood glucose levels. Negative feedback system is made out of receptors to detect change, a control centre to receive the information and process the response and effectors to reverse the change and re-establish the original state. (Anatomy Physiology, 2013) The autonomic nervous system controls the heart and has two branches; the sympathetic nervous system and the parasympathetic nervous system. When the body is undergoing muscular work, fear or stress the sympathetic nervous system will be active. When the sympathetic nervous system is active it will cause every heartbeat to increase in strength and heart rate. During resting, peace and contentment the parasympathetic nervous system is active and it calms the heart output. During periods of fright, flight and fight the sympathetic nervous system is boosted by the hormone; adrenaline. The nerves of the adrenaline are the cardiac nerves. A special cluster of excitable cells are supplied by the sympathetic and parasympathetic nervous system in the upper p art of the right atrium. We call this ‘the peacemaker’ in general terms. A connection of impulses from the sympathetic and parasympathetic nerves acting on the sino-atrial (‘the pacemaker’) regulates the activity of the heart to suit situations from minute to minute, hour to hour and day to day. The  sino-atrial node sends out a cluster of nerve impulses every few seconds around the branching network of atrial muscle fibres to cause contraction. The impulses are caught by a different group of cells forming the atrioventricular node and relayed to a band of leading tissue made of big, modified muscle cells called Purkinje fibres. In the atrioventricular node the transmission of impulses is delayed slightly to enable the atria to complete their contractions and the atrioventricular valves to start to close. The location of heart valves is on a fibrous figure-of-eight between the atrial and ventricular muscle masses.(Aldworth and Billingham, 2010) The lowest part of the brain is the medulla and is located above the spinal cord and is often kno wn as the ‘brain stem’. The two important centres for control of the heart rate are located in the brain stem. These are called the cardiac centres. The sympathetic fibres descend through the spinal cord from the vasomotor centre while the cardio-inhibitory centre is in charge of the origins of the parasympathetic fibres of the vagus nerve reaching the sino-atrial node. (Aldworth and Billingham, 2010) Baroreceptors are found in the walls of the aorta and they detect changes in blood pressure. If in the arteries a small upward change in blood pressure happens it often indicates that extra blood has been pumped out by the ventricles as result of the extra blood that enters the heart on the venous or right side. When the baroreceptors detect the change they relay the information in nerve impulses to the cardiac centres. Movement in the vagus nerve slows the heart rate down and reduces the high blood pressure to normal. Thermo receptors are receptors that are sensitive to temperature and they are present in the skin and deep inside the body. Also they relay information through nerve impulses to the hypothalamus; this is a part of the brain which activates appropriate feedback systems. During fear, stress and exertion, the adrenal gland releases a hormone called circulating adrenaline. Circulating adrenaline stimulates the sino-atrial node to work faster, therefore boosting the effect of the sympathetic nervous system. The hypothalamus activates the sympathetic nervous system when thermo receptors indicate a rise in body temperature to the brain. When the sympathetic nervous system is activated it causes the heart rate to increase. Our rate of ventilation is mainly on ‘automatic pilot’ and do not notice little variations that are the result of homeostatic regulations. We are only voluntarily controlling our breathing  when taking deep breaths, speaking or holding a breath. Breathing rate increase slightly when metabolism produces extra carbon dioxide until this surplus is ‘blown off’ in expiration. Also a period of forced ventilation will decrease the carbon dioxide levels in the body and homeostatic mechanisms will slow or stop breathing until levels return to normal. A period of forced ventilation can be for example gasping.(Aldworth and Billingham, 2010) Internal receptors relay nervous impulses to the brain about the status of ventilation from the degree of stretch of muscles and other tissues when they function as stretch receptors in muscles and tissues. Changes in chemical stimuli are detected by chemoreceptors and they supply the brain with the information. There are to chemoreceptors; the central and peripheral. The central chemoreceptors are located in the medulla of the brain and monitors H+ ion concentration. When H+ ion concentration is increased it causes increase in ventilation rate. Peripheral chemoreceptor’s increas e ventilation when oxygen levels decrease. Peripheral monitors changes in oxygen. (Aldworth and Billingham, 2010) The respiratory system has a dual autonomic supply. The sympathetic causes the bronchial muscle to relax and the parasympathetic causes the bronchial muscle to contract. This causes narrowing in bronchi. Vagus means ‘a wanderer’ and the vagus nerves is so called because it wanders all over, supplying internal organs. Sympathetic nerves emerge from the places where nerves interconnect, to run to the bronchi, these places are called a chain of ganglia.(Aldworth and Billingham, 2010) The upper part of the brain is called cerebral cortex; this part of the brain is responsible for voluntary control of breathing. The respiratory centre, also called the involuntary centre is found in the medulla and the pons. Each centre receives information of internal receptors about the state of ventilation. The respiratory pacemaker and the respiratory centre are similar to each other. The inspiratory and expiratory centres are two groups of nerve cells. If one is active the other one is inhibited. The inspiratory centre is actively sending nerve impulses to the nerve to the diaphragm, the phrenic nerve, and the thoracic nerves are sending impulses to the intercostal muscles which cause contraction and the contraction results in inspiration. Inspiration stops when the stretch receptors send bursts of impulses to the inspiratory centre. These bursts of impulses indicate that the chest and lungs are fully  expanded, and the flow of impulses subsides, releasing the expiratory centre from inhibition. The expiratory centre then sends nerve impulses to the respiratory muscles which causes relaxation and expiration. The information that comes from the other internal receptors, for instance the chemoreceptors (which effects the homeostatic regulation) monitors and modifies the cycle. The body predicts the changes before an individual starts the exercise, this is because the sympathetic nervous system is stimulated. Also adrenaline is released to rise cardiac output and stroke volume. When arterioles become narrow the blood pressure increases, whereas the arterioles in the muscle relax. The extra oxygen that is needed is received by an increase in blood flow and ventilation rate. (Aldworth and Billingham, 2010) The only animals that can survive in tropical and polar regions of the earth are human beings. This is because the efficient thermos-regulatory homeostatic processes and the use of intelligence (for shelter and clothing), which mean that body temperature changes only slightly. The importance is to keep all the organs and cells at a normal temperature while allowing the periphery to adapt to changing conditions of external temperature. When body temperature is too low the water component of the body will freeze and when body temperature is too high, enzymes and body proteins will be altered or denatured (form will alter). It wouldn’t be possible to live in these conditions therefore homeostatic regulation of body temperature is vital. (Aldworth and Billingham, 2010) The skin plays an important role in regulation of body temperature. It covers the external surface of the body and it actually is the largest organ. The skin, protects the underlying tissues against friction damage, waterproofs the body, protects against ultra-violet radiation, protects deeper structures from invasion by micro-organisms, relays nerve impulses generated from the specialised skin sensory receptors for heat, cold, touch, pain and pressure, therefore informing the brain of changes in the environment and the skin synthesises vitamin D from sunlight acting on the adipose layer. When cells are shed from the surface layers, new cells will form to replace them and this happens continuously. The skin is an important part of our in-built or innate immunity. The skin forms a waterproof layer and a microbe-proof covering. The skin has a major role in the homeostatic regulation of body temperature and is considered to be part of our nervous system; this is  because of his sensitivity. Throughout the body the thickness of the skin will differ, for instance over the eyelids and lips and on the soles of the feet. The skin is divided into an outer thinner layer and a deeper layer. The outer thinner layer is called the epidermis and the deeper layer is called the dermis. The deeper layer covers adipose, areolar, striated muscle and some cartilage and bone. Hair follicles run down into the dermis and produce hairs made of keratin. Sebaceous glands that coat the surface in hairy parts are attached to the hairs that are made of keratin. The epidermis gets penetrated by sweat ducts as they emerge from the actual sweat gland in the dermis. The dermis is connective tissue, most likely areolar in which blood vessels, nerves, sweat glands, elastic and collagen fibres intermingle. In the basal layer we can find co llections of pigment cells, also known as melanocytes and they produce skin colour. Specialised receptors for temperature changes, pain, touch and pressure are formed by nerve endings. (Aldworth and Billingham, 2010) The metabolic processes that take place in the body generate heat. Energy is released during chemical reaction for muscle contraction but some of this energy is released as heat. The body gains some heat from hot foods and drinks and sometimes from the sun’s rays. Most heat is gained of chemical reactions that take place in the liver, the liver is a massive generator of heat but it doesn’t feel hot because the blood distributes this heat around the body.(Aldworth and Billingham, 2010) The receptor for heat temperature and cold temperature can be found in the peripheral skin and around the internal organs. These receptors are specially adapted cells with nerve fibres that run up the spinal cord to the temperature control centre in the hypothalamus of the brain. Nerve impulses get send by the hypothalamus to muscles, sweat glands and skin blood vessels. This causes changes that counteract the external changes. (Aldworth and Billingham, 2010) The parasympathetic nervous system helps the unstriated muscle coats of the skin arterioles to relax, but has no significant role in thermo-regulation. The sympathetic nervous system’s function is to control sweat glands and the calibre of the arterioles. While thermoreceptors tell the hypothalamus in the brain that the temperature is rising, arterioles are expanded to let extra heat reach the surface of the skin and sweat glands get activated by the sympathetic nerves at the same time. When arterioles expand it will increase heat loss by radiation and  disappearance of sweat. When the essential temperature is decreasing (cooling down), the sympathetic is active causing contraction of the arterioles but there is no sweat ‘‘it’s turned off’’. This makes the skin c older to touch and reduces heat loss and therefore it preserves the essential temperature. Essential temperature dominates the peripheral skin thermoreceptors when conflicting information is received is the reason of the colder skin and reduced heat loss. (Aldworth and Billingham, 2010) An increase in glucose will stimulate the production of the hormone insulin from the beta cells in the islets of Langerhans in the pancreas. Glucose is produced by digestive enzymes when carbohydrates are broken down. The functions of insulin are to regulate the concentration of glucose in the blood and to increase the passage of glucose into actively respiring body cells by active absorption. Very little glucose is able to pass through cell membranes without insulin expect of liver cells, and so the plasma level of glucose rises. Individuals who have diabetes mellitus, which is caused by a lack of insulin, that are not treated will have high plasma glucose levels and this can lead to other biochemical disturbances. Glucose hardly varies at all in healthy people this is because the liver ce lls that are controlled by insulin convert glucose into liver glycogen for storage. Another hormone, glucagon, from the alpha cells in the islets of Langerhans, is secreted when blood glucose starts to fall as a result of fasting or being used up by respiring cells. The secreted hormone converts liver glycogen back into glucose for release into the bloodstream. These two hormones control the amount of glucose in the blood plasma by negative feedback mechanisms and they both have receptors attached to their islet cells to recognize increase and decrease in plasma glucose levels. Also the conversion of glucose into fat is promoted by insulin and insulin delays the conversion of amino acids into energy. It is important to identify the role of another hormone, adrenaline, in the homeostasis of glucose. Adrenal glands release adrenaline when the sympathetic nervous system is active under stressful conditions, adrenaline acts aggressively to insulin and it dominates it, to adapt glycogen in the liver to glucose. This provides energy for muscles to become active under emergency conditions. After the emergency, insulin will once more become active and store any surplus as before. (Aldworth and Billingham, 2010) In conclusion, the concept of homeostasis is explained and  the probable homeostatic responses to changes in the internal environment during exercise are discussed. In this assignment I will be explaining why homeostasis occurs during exercise and how the body responses to homeostasis during exercise. There are two types of exercise; aerobic and anaerobic. Anaerobic exercise builds muscle, power and strength. When you do anaerobic exercise, your muscles are exercising at high intensity in a short time. This short time is usually not more than about two minutes. Aerobic exercise is done at moderate level of intensity for longer periods (at least 20 minutes). Aerobic is to improve the body’s consumption of oxygen and involves mainly the large muscle groups. Homeostasis is the process by which the internal environment of the body relatively stable even with changes in the external environment. Homeostasis makes it able for the body to adapt to several conditions, for example an average human body temperature is 37 degrees. This varies slightly from individual to individual. When the temperature outside decreases your body will maintain the same temperature. This proves your body has the ability to regulate its own temperature. This is not only with body temperature but there are many other ways in which your body regulates itself, particularly during exercise.In order to maintain its normal state the body must account for and adjust functions inside the body, whenever your body feels a change on the outside. Most of the time people sweat without even thinking of why your body is suddenly dripping in moisture. During exercise, there will be a wide range of effects on the systems within the body. Each system strives to help create enough e nergy to continue exercising, also to help the body recover after exercise. This use of energy has several effects on the body’s homeostasis including increased heart rate, breathing rate and sweat rate.(wiseGEEK, 2015) Homeostasis and exercise must work together within the human body to ensure that the pulmonary, heart and muscle system function properly. Two common forms of exercise are; lifting weights or jogging down the street, these two exercises produce a stress or strain on the body. During movements of the exercise the muscles must react fast, while blood flow and oxygen levels must be redirected to compensate for the extra energy use. If an individual is jogging his breathing rate has to be higher than a person who is resting. If the individual has a lack of oxygen to any vital body system it will result in cellular damage, or injury. The extra oxygen that enters the  jogger’s lungs, which comes through the pulmonary system, helps to return balance to the body. Homeostasis refers to the human body’s balance among all vital li fe systems. When oxygen intake increases, the muscles will produce more adenosine triphosphate (ATP). Adenosine triphosphate is needed for continued muscular movement. The heart is the main muscle that is affected by exercise and homeostasis. During exercise the heart must beat quicker to move oxygen-rich blood out to the skeletal muscles for motion. When the individual slows the exercise, the heart will respond to the change in homeostasis by reducing the pumping action. Until the individual is at rest, the body will continue to change its functions to maintain homeostasis.(wiseGEEK, 2015) The cardiovascular system has chemoreceptors which are located in two places; in the carotid arteries that run through the neck to the brain and in the aortic arch, which is an arterial feature near the heart. Some of the most essential chemoreceptors notice carbon dioxide. When the chemoreceptors sense high levels of carbon dioxide during exercise, the breathing rate and heart rate is going to increase to remove the waste product from the blood. The chemoreceptors work with the cardiovascular system and the respiratory system, since the cardiovascular system ge ts carbon dioxide to the lungs for elimination and the lungs need to work harder to exhale the carbon dioxide. During exercise the blood flow supply routes change within the body. To enhance oxygen supply to the muscle cells, the stress placed across the muscular system requires more blood than normal. The body switches blood normally directed toward digestion or nervous system activities to the skeletal muscles, in response to the exercise and homeostasis requirements. Removing the stress on the muscles will result that the blood flow returns to its normal routes to achieve a resting homeostasis. In relation to exercise and homeostasis, body temperature is an important consideration. During exercise your body’s system for regulating works quicker and harder. Heat production by the body can cause your internal temperature to rise up to as high as 40 Í ¦C. This can possibly lead to fatal complications. Homeostasis occurs during exercise by allowing the body to sweat. Homeostasis occurs by allowing the body to sweat. The lossof sweat from the skin cools the body down, which results in overall temperature balance to allow continued exercise without overheating. During exercise your metabolic rate increases. Heat is produced during  metabolism. An increase in metabolic rate also increases heat production. The change in body temperature during exercise is produced by the action of large muscle groups contracting. The more heat that is produced means the higher the temperature during exercise. Muscles that have enough energy store fat for a short burst of activity, after thisthey rely on increased blood supply to deliver oxygen, blood sugar and other nutrients to produce more energy. The human body burns the sugar in the blood and calls for the liver to supply stored glucose to keep up with energy demands, which causes variation in the blood sugar when exercising. Your muscles start c alling for nutrients, as you warm up, to produce energy. Energy supplies are; glucose that is carried in the blood and delivered to the muscles and free fatty acids, which is a type of lipid that is carried in the blood that provides energy when glucose is decreased. Using energy during exercise assists in balancing high blood sugar and provides fuel at the same time. Energy supply increases at the same time as blood flow to the muscles increases. The muscle cells refer signals to start burning glucose, and more of it is delivered to the cells which lower the blood sugar levels. During exercise the amount of oxygen available in the bloodstream increases, but the body must get rid of carbon dioxide from the blood at the same rate. When the body cells make energy, carbon dioxide is produced as a waste product. The carbon dioxide goes back into the bloodstream and from there it will flow through the veins back to the lungs where the carbon dioxide will be exhaled out of the body. Your breathing rate must continue to stay at a high level, to maintain balance. Now the lungs can expel the extra carbon dioxide being produced by the muscle cells during exercise. When the individual stops exercising and the cells turn back to normal energy needs, there wi ll be less carbon dioxide that is created. This allows the breathing rate to return to normal. In this assignment I’m going to explain the importance of homeostatic within the body. Homeostasis is the control of internal situations: it maintains a constant internal environment by negative feedback. The human cells live and function in a certain temperature which means that they depend on the body environment. The body environment is kept under control by homeostasis and it keeps the condition accurate for cells to function and live. If the cells don’t get the accurate condition they won’t be able to function properly. Certain process such as osmosis and  enzymes will not function correctly. Homeostasis maintains the body’s water and salt balance, if the water and salt balance are in a good condition it will maintain the process of diffusion and osmosis. Diffusion and osmosis is the transport of chemicals such as; oxygen, carbon dioxide and dissolved food .The living cells depend on the movement of these chemicals around the body. The cells in our body are kept alive by chemical reactions; the chemical reactions make the cells do their job. Enzymes speed the chemical reactions up which keep the cell alive and also enzymes ensure that the job is done. Homeostasis is responsible for maintaining a constant body temperature and enzymes work best at particular temperatures which is maintained by homeostasis, therefore homeostasis is very important to cells. (Bbc.co.uk, 2015) Negative feedback makes sure that, in any control system, changes are reserved and returned back to normal state, for instance; keeping a constant body temperature even in a hot or cold environment. Shivering is a reflex which is controlled by the nervous system. Without homeostasis the human body would not be able to function in hot or cold temperature. Shivering is a way to warm the body up, because it generates heat. If an individual is cold, homeostasis occurs and sends signals to the body which causes the reflex of shivering. Sweating is the opposite of shivering. If the body has an absence of sweating, which is also defined as hyperhidrosis, it can affect small and large areas within the body. Sweat is important for the human body because it keeps the human body cool, gets rid of excess body heat and protect from overheating. If an individual is not able to sweat it can be very dangerous, that’s why it is important to maintain homeostasis. Not sweating in whenever the body is hot can lead to serious damages and injuries, such as coma and death. It is important that the human body has homeostasis, because a failure in maintaining homeostasis can lead to death or diseases. For example heart failure can occur when negative feedback mechanisms become overwhelmed and unhelpful positive feedback mechanisms take over. Diseases that can occur from a failure in maintaining homeostasis are; diabetes, dehydration, hypoglycaemia, gout and any other diseases that are caused when toxin gets into the bloodstream. (wiseGEEK, 2015) A failure in maintaining energy balance can result in obesity and diabetes. Obesity is caused when a person overeats. The stomach releases a hormone whic h is called hormone ghrelin. This hormone goes to the  brain and increases a person’s appetite. The answer will come from another hormone which is named Leptin; this hormone is produced by cells in the fat tissue. Leptin goes to the brain and encourages a sense of satiety, or fullness. If the brain refuses to respond to ghrelin, an individual will keep feeling hungry. If the brain refuses to respond to the hormone Leptin, an individual will never be happy from a meal. Therefore a person will keep on eating and a person may overeat and this causes obesity. Homeostasis maintains energy balance. Without homeostasis an individual would overeat. (Biology-online.org, 2015) Homeostasis is also important in fighting viruses inside the body. For example if someone in your environment spread flu when he/she sneezed, your body will be affected. The body needs to fight off the entering virus, which likes living at normal body temperature. At 37á µâ€™ C the virus is able to breed and reproduce/multiply well, this will make the individual more prone to the illness as there is more bacteria to spread it. Although the body wants to maintain homeostasis and a normal temperature, but it would result that the v irus takes over your entire body. Therefore the body temperature rises above the normal range. When the body temperature rises it makes the body an uncomfortable place to live for the virus. In hotter temperature, the virus will slow down and you immune system will be able to attack the virus. Therefore homeostasis is very important, it helps fighting illnesses. If homeostasis would be disrupted an individual would become sick. A failure in homeostasis can result in dehydration. Maintaining water balance is important for good functioning of nerves. The kidney can detect blood pressure and the brain can detect the amount of water in the blood. The brain makes the body ‘thirsty’ when water levels in the body are low, while sending signals to the kidneys to retain more water. Dehydration occurs when there is too little water and it can cause kidney damage, heat cramps, shock, and coma and organ failure. However, when an individual drinks too much water, it can cause hyper hydration. Hyper hydration can lead to weakness, confusion, seizures and irritation. The human body’s weight is more than the half percentage of water. Homeostasis maintains the correct balance of water. (Balance, 2015) Homeostasis has a survival value, because it allows the human body to adapt in a changing environment. It deals with the temperature difference that a human faces when they step out their front door. The body will try to maintain a norm, the desired level of  a factor to achieve homeostasis. But it can only work within acceptable limits. In extreme condition the negative feedback mechanism can be disabled. In these circumstances, death can be caused unless there is medical treatment.

Gothic horror Essay

All three stories are based on the Victorian era, they are all examples of Gothic horror. Gothic horror is shown to scare the the reader. the gothic era normally has a typical ghostley setting, it has to be mysterious and nothing is explained or even described! â€Å"Most gothic novels are tales of mystery and horror intended to chill the spines and cradle the blood. They contain a strong element of super natural†. Most gothic has alot of tension. There is an even stronger build up of tension in short stories. There three stories show elements and forces beyond an individuals control, Starting off with the ‘tell tale heart’ where here shows that the narrator is mad and signs of schizophrenia as he thinks he is hearing thing, â€Å"above all was the sense of hearing acute† narrator is also questioning the reader which makes us guess hes going mad. The narrator never pretends to be innocent, fully admitting that he has killed the old man because of the victims pale blue, film-covered eye. Then when he kills the old man dued to paranoia, he starts to hear old mans heart beats which makes him confess his wrong doing. The ‘red room’ we can infer that the narrator firstly shows eagarness and confidence â€Å"you will show me to this haunted room† his mppd starts to swing into a different emotion as he shows fear â€Å"the memory of that story gave me a suddden thinge of apprehension†. Finally he becomes a shrieking wreak and admits it was fear that haunted him. In ‘Confession found in a prison we all gather that the narrator is ill and suffering from paranoid and madness, this is shown by when killing the boy who looks at him at the same way his mother mad. This story being in first person gets the reader into the mind of the character and tells them his emotions and how he feels in the situation. The story starts with the narrator explaining, â€Å"this is the last night I have to live† This sentence draws in the reader with curiosity as to why it is his last living night. The victorians found alot of intrest in the human brain as they knew more about it dued to science, they used to lock away insane, disability and single women with children, they were never realeased, many people were tortured to be ‘cured’. The setting in the red room is set around the room, we know its old as it â€Å"creaks on its hinge†. The red room isn’t explained about much which makes the room mysterious. This settng would be frightening as paranoia would be as it would be if it was silent and dark so the slighest of sound could scare the day lights out of you. â€Å"i walked down the chilly, echoing passage†. This would frighten the reader as â€Å"chilly† shows ge is cold. â€Å"echoing† shows he is alone. He must scared as he can point out every second that happens. The writer emphasises many aspects of the place where the supernatural tale could take place. The tell-tale heart is mainlysetted in the old mans bedroom. This room is scary as the writer uses alor of suspence to get you frightened â€Å"you cannot imagine how stealthily, stealthily until at length a simply dim ray, like the thread of the spider, shot from out the creavile and fell upon like the vulture eye†. This actions are very slow and meliculous, he is worried about every tiny detail â€Å"upon the eighth night i was more usually cautious in opening the door’ and when i had waited a long time, very patiently, with out hearing him lie down†. Confession found in a prision is set in a prison but the murder was set in the house. The short story ‘Confessions found in a prison’ shows the narrator to be a paranoid and obsessive character, this is shown when the narrator watches the spot where the child is murdered for a whole day. The reader can also see his conscious playing on his mind as he dreams that he did not kill the child, but wakes in ‘dreadful agony’ realising that he had murdered the child. I Think ‘confessions found in a prison’ makes the most fear for the reader as a child is murdered by his guardian, this story is very disturbing as the murder is made by somebody who is supposed to love and care for the child. These three short stories, if modern to this day, could still create fear in many readers today. Many books with the same storylines are still popular with today’s generation and are just as spine chilling and blood curdling as they were in the Victorian

Boeing/Airbus Evaluation

MBA 654 Case 10. 1 Boeing & Airbus Robin Grouette 1. The overall strategy for Boeing seems to be focused more on customization and efficiency rather than size. With the focus of the 787 Dreamliner being that of long range with smaller passenger capacity, Boeing is anticipating that more direct routes to international cities will be developed rather than the typical hub and spoke routes which currently dominate the airline industry.Airbus’ overall strategy is focused more on the hub and spoke routes as well as improving efficiency. The A380 has utilized new materials in both airframe and wing compositions which have not been seen in Boeing’s products. The A380 also relies heavily on travel between concentrated hubs of passengers to ensure capacity is not underutilized. Airbus does seem to be playing a bit of catch-up in announcing the A350 for a 2012 release as it is positioned to compete directly with the 787 from Boeing.The ways in which both strategies are different w ould be the focus of Airbus on centralized hub and spoke routes for airlines (major city to major city) and creating larger aircraft to support their strategy, as compared to the decentralized connectivity to international destinations (smaller cities connected to smaller cities) which Boeing believes to be the coming evolution of air travel. The similarities in both strategies focus around efficiency and range.Almost the entirety of both new product developments for both companies have seen significant increases in flying distance in comparison to previous models. Also, with the rising cost of fuel, the efficiency of design and materials has been become more important. Airbus has developed its product line in response to the strengths and weaknesses shown by Boeing. An example would be the A320 family which was introduced 20 years following the 727/737 models from Boeing.All models involve smaller capacities and ranges which would suit regional and national travel. Airbus also deve loped a medium range/capacity A300/310 model to compete with the 757 and 787 from Boeing. In both the small range/capacity and medium range/capacity, Boeing had a long established dominance in model acceptance as well as an ability to provide upgrades in technology and efficiency at a smaller cost to replacing the entire plane, which left Airbus at a disadvantage.Where Airbus’ real advantage came in the long range/large capacity segment which had only been serviced by the 747 from Boeing. With the introduction of the A330/340 in the late ‘80’s as well as the A380 in 2008, Airbus is anticipating the need for long distance, major hub connections throughout the world rather than having smaller cities having the ability to have direct flights to international destinations . 2. The product lines for both companies fall into three categories: short range/small capacity, medium range/medium capacity, long range/large capacity.Both companies have four models in the short range/capacity segment, Airbus has 2 models in the medium range/capacity segment to Boeing’s 3, and Airbus has 2 models in the long range/large capacity to Boeing’s 1. The sales for each segment is dominated largely by Boeing with 9632 units sold between 1970 and 2005 in comparison to the 5797 that Airbus sold in the same time. While being dominated in the small and medium segments, Airbus has been exceeding Boeing in the long range segment since the 90’s.In terms of technology, both firms are making advances towards efficiency as well as fly-by-wire controls. While Boeing models have been established for quite some time, Airbus has utilized their late entry into the industry by incorporating the latest technology into their products. Aircraft were originally designed with direct mechanical systems, meaning that when the pilot depressed a pedal in the cockpit, the corresponding surface on the airplane would react by how hard/fast the pedal was depressed.In mode rn aircraft, this mechanical system has been replaced by a fly-by-wire system which an electrical signal is sent to the surface from the cockpit, rather than a mechanical one. Airbus has been utilizing this technology exclusively in their products, whereas Boeing has had to create upgrade packages for their existing products to switch to the new technology. Airbus has made a leap in material component technology which Boeing has not, in the Lithium/Aluminum body composition as well as carbon fiber wing construction for the new A380.Overall I believe that the Boeing approach to a more decentralized, medium capacity aircraft with long range and high efficiency will prove to be the better product line. Airlines are creating more direct flights to international destinations and having the ability to have a larger percentage of capacity utilized on the medium capacity planes will make the 787 more desirable to airlines as they continue to evolve. 4.The overall economics of the industry i s one of stiff competition supporting an industry which has been struggling to make a profit for the last decade. Both companies are competing for the limited capital available to their customers to provide new products while at the same time, staying current with evolving regulations around noise and efficiency. Also, both companies are competing on a wide variety of factors for all three sales segments so creation of new products to meet customer needs are both costly as well as risky.The importance of government subsidies for both companies is paramount. This helps transfer the financial risk of new product development across more participants. While Airbus gets directly subsidized from a number of European governments, Boeing is indirectly subsidized through their military contract business. Boeing’s issue with the direct subsidies are that they can be directly traced to the commercial aircraft industry while their indirect military subsidies are harder to uncover.In the end, both companies are being subsidized by government funds. While the level of subsidization may not be exactly the same for both companies, making an issue about the only other competitor in the industry receiving a subsidy while you are as well comes across as a double standard. 5. New products are developed by creating very long range forecasts and anticipating the evolving needs of their customers before they may even realize them; all at a tremendous R&D cost to the developing company.While most of Boeing’s products were developed in the 60’s and 70’s, they really hadn’t come out with anything new until 2006 and then again in 2010; whereas Airbus has had a more consistent release of new products since the 80’s. The major trade-off between fuel efficiency and cost are based on the ability to upgrade existing models over the improved technology and materials in the newer models. Since Boeing has had an established product line for a longer tim e than Airbus, they are able to compete by selling upgrade packages to improve technology and fuel efficiency rather than having to replace the entire plane.While this has worked for Boeing in the past, this approach may have stagnated the creative drive of designers in coming up with new models, which Airbus has been doing. The A380 may not be a serious threat to Boeing, depending on how the global airline industry adapts to more people flying. If the hub and spoke method which is currently employed persists well into the future, then Boeing could be at a disadvantage to Airbus as their large capacity 747 is almost 50 years old and there are no current plans to replace it.On the other hand, if airlines start offering more direct flights from a wider variety of cities, the 787 Dreamliner is excellently positioned to take advantage of both longer ranges as well as smaller passenger requirements for profitability. 6. There will be new competitors entering this industry either directly or indirectly. Direct competition could be developed in Asia as more and more people use air travel as well as an increase in skilled labour. Indirect competition could also evolve from privatized space travel.While currently only found in science fiction, the ability for aircraft to travel semi ballistic is not far off. Having the ability to travel tremendous distances at greatly reduced times would be a major draw to people who use airlines for international business. Boeing needs to be aware of the progress of the privatized space flight industry as well as any potential competition from Asia. This means more investment into technology around fuel efficiency as well as materials and systems. When Boeing offered upgrades on their 747, they reduced the total crew required from 3 to 2, saving $400,000 per year in operating costs.If they could further reduce crew requirements to a single pilot, it would provide significant operational savings to their customers. The future of the co mmercial aircraft industry is bright. Air travel is the safest and fastest way for people to travel long distances. With evolutions in engine and plane design, the models will only get faster and more efficient. The key for each company is to not wait to see what the other is doing, but to invest in both market research and technology to stay ahead of the other.

Animal Navigation essays

Animal Navigation essays Animal navigation and sense of direction without maps or any assistance has been a mystery, in terms of migration and travel by birds, fishes and insects. Their ability to use different cues to enable themselves to navigate to their destination is amazing. These animals utilize various methods to guide themselves through unfamiliar terrain to get a different area. Some animals use the sun and stars to guide their way to warmer climates. Others may use their sense of smell, or light to direct them. While it has been proposed that some animals are genetically predisposed of having the ability to migrate, it may be debunked or renewed by the theory that animals are guided by a magnetic field. In the article it explains that the core of the earth has a magnetic strip which depending on its intensity can guide animals in different directions. However a question was posed about the ability to detect such a small electric field. Since this magnet is in the core of the earth the intensity on the surface is so weak that how could an animal possible be able to use this source or cue. Well after endless experiments it is concluded that some animals that use this technique can detect electric fields as weak as five-billionths of a volt per centimeter. Applying this new idea to the migration of sea turtles. This experiment concluded that the turtles used the magnetic field as navigational markers. These markers guide them through the ocean, allowing the turtles to avoid fatally cold currents and stay on a path leading towards home. Because of the intensity of the magnetic field these turtles are able to avoid harmful things. Young sea turtles inherit a set of instructions that help guide them along their migratory route. This means that different groups of sea turtles in different parts of the world have probably evolved different instructions that work only for the particular migratory pathway that they follow.

Take Public Transportation - Save Money, Save The World

Take Public Transportation - Save Money, Save The World If you want to help reduce global warming, air pollution, and your monthly living costs, one of the best things you can do is to get out of your car. By walking or riding a bicycle for short trips, or taking public transportation for longer ones, you will significantly reduce the amount of pollution and greenhouse gas emissions you generate each day. The Rising Environmental Cost of Driving Alone Transportation accounts for more than 30 percent of U.S. carbon dioxide emissions. According to the American Public Transportation Association (APTA), public transportation in the United States saves approximately 1.4 billion gallons of gasoline and about 1.5 million tons of carbon dioxide annually. Yet only 14 million Americans use public transportation daily while 88 percent of all trips in the United States are made by car- and many of those cars carry only one person. Added Benefits of Public Transportation Cutting back on carbon emissions and costs usage isnt the only added benefit of using public transportation. It also helps increase the energy independence of the country overall. Although an increasing amount of our oil is produced in North America, the majority of it still comes from across the pond. Public transportation is also safer, a lot safer, in fact. Riding a bus is 79 times safer than riding in an automobile, and riding a train or subway is even safer. Its also healthier, studies have shown that people who use public transportation regularly tend to be healthier than people who do not, because of the exercise they get walking to and from bus stops, subway stations and their homes and offices. And of course, theres the reduction of costs overall. According to an APTA study, families that use public transportation can reduce their household expenses by $6,200 annually, more than the average U.S. household spends on food every year. The Heart of the Debate Over Public Transportation So why don’t more Americans use public transportation? Transportation experts and social scientists may argue about which came first, America’s attachment to the automobile or the urban and suburban sprawl that makes long daily commutes in at least one and often two cars a requirement for many American families. Either way, the problem at the heart of the debate is that good public transportation systems are not available to enough people. While public transportation is readily available in many major cities, the majority of Americans in smaller cities, towns and rural areas simply do not have access to good public transportation options. So the problem is twofold: People with access to public transportation has to be persuaded to use it more often. Additionally, more affordable public transportation options in smaller communities need to be created for use. Trains, Buses, and Automobiles Train systems are the most efficient in many ways, typically emitting less carbon and using less fuel per passenger than buses, but they are often more expensive to implement. Also, the traditional advantages of trains can be mitigated to a large extent by using hybrids or buses that run on natural gas. Another promising alternative is bus rapid transit (BRT), which runs extra-long buses in dedicated lanes. A 2006 study by the Breakthrough Technologies Institute found that a BRT system in a medium-sized U.S. city could reduce carbon dioxide emissions by more than 650,000 tons during a 20-year period. If you live in an area with good public transportation, do something good for the planet today. Park your car, and take the subway or the bus. If you don’t, then talk to your local and federal elected officials about the benefits of public transportation and how it may help solve some of the problems they’re wrestling with right now.

Change the united states into a Utopia (the word means nowhere). What Essay

Change the united states into a Utopia (the word means nowhere). What changes should me made and why should they should be made - Essay Example There are several things that can be done to change America to utopia. Some of these things may have certain disadvantages. However, it is also true that majority of benefits may accrue from them. One of the things that may be done to change America to nowhere is ensuring that barriers are limited for the international community to access America (Frazier et al, 31). This may be done by reducing the number of requirements as well as qualifications that anybody wishing to come to America may have to meet. This may include reducing the number of policies that bar such movements involving migrations as well as immigrations to America. The influx of such people to America is quite advantageous to the American society as well as America as a whole. This is because, when the rate of immigration is heightened, a number of people will find their way into the country. This will be economically beneficial in a number of ways. First, the rate of consumption of the American goods by such a growi ng population will massively shoot. This will place more demands on the goods and services from the American industries thereby impacting positively on the businesses in America. This is quite beneficial to both the American society as well as America as a country. This follows that the economy of the country will be affected in an appreciating perspective, thereby leading to more economic stabilization (Frazier et al, 41). In addition, it is of crucial significance to note that the process of learning is always affected in a certain manner following the entry of alien individuals in a new land. Therefore, changing America to nowhere relates to an increase in accessibility of the country by people of different origin, races, ethnicity as well as cultures (Frazier et al, 47). This promotes the issue of intercultural education. This helps in
