Phonology - Case Study Example And when producing pp, the lips will be stretched to produce y. The whole word is uttered in half a second. Elision: Elision is the loss of a phoneme. I.e. the omission of sounds (vowel/consonant/syllable), so that the speaker can simplify the pronunciation. This usually occurs in a fast speech and is normally unintentional. Allophone: Allophone is a phonetic variant of a phoneme in a particular language. I.e. it is one of the several speech sounds belonging to the same phoneme. A change in allophone does not alter the meaning, but rather makes the word sound non-native. Minimal pairs enable the linguists to build up the phoneme inventory for a language or a dialect. Though the words differ by only one segment, there may be wide variations in terms of articulation. However, most minimal pairs are considerably distinct and hardly pose inconvenience to the speaker or listener. Complementary Distribution: it is the mutually exclusive relationship between two phonetically similar segments. It exists when one segment occurs in one particular environment and the other occurring in an entirely different environment. Example: Consider the allophones [p'] and [p]. ... Example: Consider the allophones [p'] and [p]. [p'], the aspirated phoneme occurs when there is a syllable onset and is followed by a stressed vowel (as in the word put) and the unaspirated phoneme [p] occurs all other times. Here we see complementary distribution in similar phones. Every time it need not be allophones. For example,[h] and ['] are in complementary distribution, since [h] only occurs at the beginning of a syllable and ['] only at the end. Since they have hardly anything in common in phonetic terms, they are better considered as separate phonemes. Phonological conditioning and conditioning factors: Consider the words- cats, dogs, judges. The final sounds- /s/, /z/, /s/ occur after the sounds /t/, /g/ and /'/, respectively. When the distribution of the various allomorphs can be stated in terms of their phonemic environments, the allomorphs are said to be phonologically conditioned. Phonological conditioning is the most general and productive kind of conditioning of morphemic variants in languages. Phonemic overlapping: Biuniqueness: It is a principle which provides a one-to-one correspondence between phonemic and phonetic levels of analysis. A phonemic description is said to be biunique if phonemes and allophones are unambiguously mapped on to each other. Example: send and sent pronounced as /sent/ and seed and seat pronounced as /si:t/. Neutralization: phonemes that are contrastive in certain environments may not be so in all environments. In those environments where they do not contrast, the contrast is said to be neutralized. Example: consider the word sum: /s'm/. In another word, plumber: /pl'mb'/, since /m/ is followed by a plosive sound /b/, the contrast is lost. Archiphoneme: This is an abstract phonological

Controversial issues in education - Is home education beneficial for Essay

Controversial issues in education - Is home education beneficial for children - Essay Example Home schooling allows the parents to determine the content of the syllabus based on the legal and social provision of a particular state. Various education bodies in the country monitor the conduct of both parents and children in order to ensure the children acquire adequate and appropriate education (Lampmt and Wuthnow, 2008). The concept of home schooling started in 1970s after some educators begun encouraging the parents to conduct tuition for their children at home. Educators and researchers such as Raymond Moore, Dorothy and John Holt led the home schooling movement (Sheng, 2013). The individuals conducted massive campaigns in various schools, media and households encouraging the parents to adopt the home schooling system in order to reduce the cost of education. In addition, they encouraged the parents to utilise home schooling as an avenue for enhancing their relationships with the children (Collom, 2002). The arguments of the researchers were based on the idea that the traditional public and private school environment interfered with the morality of the children. In addition, the scholars highlighted that children concentrate more under the supervision of their parents than under the teachers’ guidance. The idea of home schooling continues to grow significantly in United States because most parents prefer to tutor their children at home. Research indicates that most of the young generation parents prefer home schooling their children in order to enhance their morality and quality of education. In addition, other parents engage their children in home schooling system in order to uphold particular religious beliefs in the society (Mur, 2003). For example, Muslim families in United States educate their children at home in order to incorporate the religious concepts in their training (Aurini and Davies, 2005. Additionally, parents

Electric Vehicles Technology Analysis Essay Example for Free

Electric Vehicles Technology Analysis Essay Hybrid electric vehicles are one of the applications of hybrid technology in real modern life; in which it’s currently a high demand technology and is growing rapidly. Although hybrid vehicles weren’t the latest type of transportation technology to be discovered, since they appeared earlier than gasoline vehicles, because of the cost of research and technology they disappeared a prosperous century of gasoline vehicles began. Nowadays, when the world needs green transportation because of high fossil costs and political reasons, hybrid vehicles returned and development into that type of technology is kicking back to full speed. Hybrid vehicles are the combination between electric engines and gasoline engines. Therefore, they inherit all the characteristics of traditional vehicle and add new functions of electric motor to help the vehicles save energy as well as reduce greenhouse gas emissions. Many vehicle manufacturers such as BMW, GMC, and Toyota are applying hybrid technology in producing their cars. One of the main reasons that hybrid vehicle are not as popular as regular gas powered vehicles is their prices. Most consumers don’t want to pay the extra $5,000- to $8,000 price tag to buy a vehicle that they don’t see the instant benefits of. Nevertheless hybrid vehicles will bring the benefits to their users and the environment, but not immediately when they buy the Hybrid vehicle. While in use, Hybrid vehicles will reduce the fuel consumption by an average of 42% which in return would be also good for the environment as it reduces greenhouse gas emissions by about 42% than the usual amount. However, in addition to what Hybrid vehicle offers the public in money savings by consuming less fuel and supporting a greener environment, it also made it possible for the public to accept alternative power sources for their vehicles. Also, hybrid technology has helped expand the research into battery power, battery life and battery size which helped in emerging of newer technology of fully electrical cars that doesn’t use any gas, for example: The Nissan Leaf. In the meanwhile, currently the available fully electrical vehicles (Nissan Leaf) on the market have advantages of totally being gas independent, and faster acceleration than some of the hybrid cars (I personally test drove the Nissan Leaf both on city streets and on the highway and I think it accelerated a lot better than my 2010 Toyota Prius hybrid. ). In my opinion the technology still not fully developed to be the most reliable form of transportation for an individual or a house hold use, since you can’t drive more than 100 miles per full charge as advertised; which I am sure it’s a little bit less based on consumers review (around 75-85 miles per full charge. ) In the near future I can imagine that fully electrical cars be more reliable and go in between 700 to1000 miles per full charge, of course it will take its course of development just like any other new technology that starts small and gets bigger by time. I imagine in the next couple years electrical cars will be able to go anywhere in between 100 to 200 miles per charge, then in the following few years from 200 to 300 miles per full charge, etc†¦ Furthermore, in my opinion I think that gas engines are a thing of the past and I can see in the future Hybrid engines and electrical engines replacing everything that we are using today, from gas powered vehicles to airplanes, from motorcycles to scooters and lawnmower to children toys. In conclusion, the human race is using new technologies to try to fix the harm they caused the environment by creating products that don’t contribute to the pollution of our environment and many consumers hope that hybrid and electrical motors technology would help reduce the pollution and contribute to help save our environment.

Economic Topics Essay Example for Free

Economic Topics Essay Discuss how the government can use discretionary fiscal policy and automatic stabilisers to stabilise fluctuations in real GDP. What tools does the government have at its discretion to stabilise the economy? Suppose the government decides to decrease income taxes. Show in a diagram and explain how this policy will lead to an increase in real GDP. Explain how potential output may be affected. Any government program that tends to reduce fluctuations in GDP automatically is called an automatic stabilizer. The reduction in economic activity automatically reduced tax payments, reducing the impact of the downturn on disposable personal income. Furthermore, the reduction in incomes increased transfer payment spending, boosting disposable personal income further. Fiscal policy is the use of government expenditures and taxes to influence the level of economic activity; it is the government counterpart to monetary policy. Fiscal policy is the best counter-stabilisation tool available to any government. Discretionary government spending and tax policies can be used to shift aggregate demand. Expansionary fiscal policy might consist of an increase in government purchases or transfer payments, a reduction in taxes, or a combination of these tools to shift the aggregate demand curve to the right. A contractionary fiscal policy might involve a reduction in government purchases or transfer payments, an increase in taxes, or a mix of all three to shift the aggregate demand curve to the left. Income taxes affect the consumption component of aggregate demand. A reduction in income taxes increases disposable personal income, increases consumption (but by less than the change in disposable personal income), and increases aggregate demand. That shifts the aggregate demand curve rightward by an amount equal to the initial change in consumption that the change in income taxes produces times the multiplier. Suppose, for example, that income taxes are reduced by $200 billion. Only some of the increase in disposable personal income will be used for consumption and the rest will be saved. Suppose the initial increase in consumption is $180 billion. Then the shift in the aggregate demand curve will be a multiple of $180 billion; if the multiplier is 2, aggregate demand will shift to the right by $360 billion. Thus, the equilibrium level of real GDP rises to $12,260 billion, and the price level rises to P2. $12,000 $ 12,260 $12,360 The economy shown here is initially in equilibrium at a real GDP of $12,000 billion and a price level of P1. A reduce of $200 billion in the level of Income Taxes (ΔT) shifts the aggregate demand curve to the right by $360 billion to AD2. The equilibrium level of real GDP rises to $12,260 billion, while the price level rises to P2.

Definitions in Anatomy and Physiology

Definitions in Anatomy and Physiology Anatomy is a science for the study of different parts of living organisms, animal or plant types either by sectioning or other methods; it studies the size, structure and the relating elements, structuring a body, a plant, etc. We distinguish general anatomy, which also takes into account the analysis of physiology. Physiology is the study of the mode of operation of the numerous existing living creatures. Specifically, it is about understanding how the human body works, the role of each organ and its functioning mechanisms found in the organism but also, the function that each living organism occupies in its environment. When referring to the human anatomy and physiology, we are likely to be using the pathology to understand when the human body faces diseases and illnesses, caused by the dysfunction of certain organs and the symptoms that help specialists and scientists diagnose certain illnesses. To understand the human anatomy, scientist and biologists use various anatomical terms to describe and locate parts of the body, so what are the directional terms, body planes and the terminology used to identify the various body regions? We start with the directional terms, terms used by the anatomists and medical professionals to identify, locate and explain the body structure and positioning in regards to another. As we can see below:      Ã‚   Definition Description Example Superior A structure above another The chin is superior to the navel Inferior A structure below another The navel is inferior to the chin. Superficial Towards or on the   surface The skin is superficial to the muscle Deep Away from the surface, internal. The lungs are deep in the ribs Lateral Away from the midline of the body The nipple is lateral to the breast bone Medial Towards the midline of the body The nose is medial to the eye Proximal Closer to the point of attachment to the body than another structure The elbow is proximal to the wrist. Distal Farther from the point of attachment to the body than another structure The wrist is distal to the elbow Anterior The front of the body The navel is anterior to the spine Posterior The back of the body The spine is posterior to the breastbone Ipsilateral On the same side of the body Right arm and shoulder Contralateral On opposite sides of the body Legs Parietal Relating to a body cavity wall Bones of the skull Visceral Relating to organs within body cavities Lungs The diagram below explains the directional terms. Blank Canvas taken from Google. Figure.1 Figure 1. Directional Terms in Anatomy. To understand the human body better, there are ways of facilitating the understanding of what lies inside, structure wise, body planes are one way. Sagittal plane is a vertical plane that divides the body into equal right and left halves. If we cut the person in a straight vertical line from the head through the belly button and down to the toes, the median plane, therefore, result equal right and left halves of the body. See Fig.2 Coronal plane is a line/cut that separates the body into anterior and posterior parts, splits the body into front and back halves. This type of division is why the coronal plane is sometimes referred to as the frontal plane. See Fig.2 Transverse plane, this is a plane that divides the body into superior and inferior portions. This plane runs perpendicular to the coronal and median planes and in an upright human is parallel, or horizontal, to the ground. This is why its also called the horizontal plane. Anatomy and Physiology for dummies. See Fig.2 Blank canvas taken from Google. Fig.2 Figure. 2 Body Planes in Anatomy If we take the body standing in the following anatomical position as shown below Fig.3, I can recall these major regions (from the outside of the body) and how they relate to each other in the anatomical position highlighted as follows: The cephalic region (head) or cranial region (skull) is at the top of the body and visible from the front and rear. The cervical region (neck) starts below the head, ends at the thorax, and is visible from the front and rear from under the head to the shoulders. The dorsal region (back) runs from immediately below the neck down to the area below the waist. It doesnt include the shoulders. Its visible from the rear. The thorax starts immediately below the neck, at the clavicles, and ends along the bottom of the rib cage. Its visible from the front. The abdomen starts along the bottom of the rib cage and extends to the hips. Its visible from the front. The pelvis starts where the abdomen ends and takes up the area between the hip bones. The perineum is between the thighs so very little is visible in the anatomical position. The upper extremities include the shoulders, arms, forearms, elbows, wrists, and hands and are visible from the front and the back The lower extremities include the hips, buttocks, thighs, knees, legs, ankles, and feet. The buttocks are visible only from the rear, but the rest of the lower extremities are visible from the front and the rear. Figure.3 Anatomical regional terms annotated diagram (blank canvas taken from Google) Part B: In histology a study of cells and tissues, the human body is a synchronised cycle of components, a structure harmonised and coherence between chemicals, cells, tissues, organs and systems to form a human body. As detailed briefly in the following order: Every organism, humans, animals and plants are formed of cells. Animal cells and plant cells have a joined characteristic like a nucleus, cytoplasm, cell membrane, mitochondria, and ribosomes. Plant cells have a cell wall, and most of the time a permanent chloroplast and vacuole. Each and specific cell has a special task or particular function, although there are different type of cells, the basic structure of a cell remains the same. Solutions pass into and out of the cells by diffusion; this sometimes is called osmosis when the water passes into and out of the cell. So what are the cell and tissue types and their functions in the human body? A group of different types of cells form tissues in the human body and one or more types of tissues form organs that work together in a harmonious manner to form the organ system. Nerve cells: These cells do not multiply in a human body life time. Once formed during fetus, they live till the entire life of a human body. They exist all over the body and some are as long as a few meters long. There are human brain cells and are found in a massive population in the brain and the spinal cord this is what forms the nervous tissue. Bone cells (Osteocytes) These are considered the toughest body cell systems and are bound together by calcium and phosphate, they give strength, support and framework to the body by enclosing organs in skeletal system i.e. bones. Cartilage cells (chondrocytes) these cells are made of a loose and flexible material. We find them in the ear, spinal bones, joints etc. Muscle cells:   There are three types: skeletal, cardiac and smooth muscle cells and are rich in proteins actin and myosin, muscle cells can contract and relax to provide movements. Secretory cells: These cells secrete and form glands, for example: pancreatic cells which secrete insulin, glucagon, salivary gland secrete saliva, sebaceous gland secrete oil on the skin. They are found in all secretory organs. Adipose cells: These are fat cells and considered as storage to store fat. Example: the soles, palms, buttocks, etc. They reduce friction to the body. Blood cells: They are always mobile and active carry oxygen and nutrients to all cells and organs. They have limited life span and they never multiply to form new cells. Instead new cells are formed from other cells. As we know, there are four types of tissues, Epithelial, Connective, muscular and nervous as I explained in the examples above. Epithelium: its main function is to protect the human body from the outside world acts as a barrier i.e. skin. It also absorbs i.e. stomach and intestinal lining (gut). Also, it filters, i.e. kidneys and it secretes as the glands do. Its also good at fixing itself, regenerating i.e. skin burns. Connective: its main function is bound together, wrapping around and cushioning and protecting organs. Stores nutrients and give an internal support for organs, i.e. tendon and ligaments protect joints and attached muscles to bone and each other, it runs through organs and in deep layers of skin producing strength. Nervous: this is very important as it is the communication element in the body to receive and give signals, this conducts impulses to and from body organs via neurons i.e. brain, spinal cord and nerves. Muscle: this is responsible for the body movements, moves blood, food, and waste bodys organs and responsible for the mechanical digestion.

Legal Issues Surrounding First Aid Essay -- essays research papers

First aid is the initial care given to a sick or injured person before more formal medical assistance is applied. The goal of first aid is to intervene actively to prevent further damage, to provide life support, and to begin effective treatment of the victim's condition, to minimize injury and prevent death. Although first aid is not a substitute for medical care, those trained in first aid are able to assess the nature and the extent of an emergency and determine the best course of action to take until professional medical help arrives. The need for training in first aid is evident, considering that injury is the fourth leading cause of death. Falls are the most common cause of injury, but motor vehicle accidents are the most lethal, accounting for 22 percent of injury deaths. An important thing to know when dealing with a first aid situation is to be up to date as far as procedures are concerned. Procedures like slapping a choking person on the back, putting iodine on a wound, cutting an X on a snake bite, putting ointment on burns, or using a tourniquet to stop bleeding are old, out dated procedures and have been replaced by new ones from the Red Cross association. If you decide to administer first aid, be sure you are familiar with current procedures. First aid begins with a scene survey. Before approaching a victim, a survey of the area is necessary to determine if conditions surrounding the incident may place the victim and the rescuer in danger. Next, the primary survey will determine if lifesaving procedures must be immediately performed to save the victim's life. The primary survey involves checking the ABC's: A: Is the airway opened and the victim's neck stabilized? B: Is the patient breathing? C: Is the victim's blood circulating? Is there a pulse? Or is there active bleeding? Lifesaving procedures include cardiopulmonary resuscitation , which may be needed to provide basic life support when a victim has no pulse and is not breathing. The Heimlich maneuver aids choking victims by forcing ejection of obstructing material from the windpipe. The severity of spinal cord injuries has decreased 30-45 percent due to awareness that the neck must be stabilized before moving the accident victim. External bleeding is controlled by direct pressure and elevation of the bleeding site. The secondary survey is a total body examination, ... ...ng. The careful use of this skill and training will not only enhance the physical welfare of the persons you care for but will also enhance your own legal welfare. On a closing note, here is a copy of Indiana's Good Samaritan Law as an example of almost every other states Good Samaritan Law. "From and after the effective date of this act, no civil action can be brought against a person licensed to practice the healing arts in the state of Indiana, who has gratuitously rendered first aid or emergency care at the scene of an accident, casualty or disaster to a person injured therein, for the recovery of civil damages as a result of any act or omission by the said person rendering such first aid or emergency care in the rendering of such first aid or emergency care. This immunity does not apply to acts or omissions constituting gross negligence or willful or wanton misconduct." As you can see, there is essentially nothing to lose if you administer first aid as long as you try your best to help and know what you are doing. Keep in mind that helping someone in a life and death matter is a very big commitment, so make sure you are willing to do so before you act.

Surge Irrigation Essay -- Technology Science Agriculture Essays

Surge Irrigation Surface irrigation is not new technology, but through research and the incorporation of some inventive measures, advances in this area have provided the needed responses to make this type of irrigation increasingly appealing. Not only is water quality a major concern, but current farmers must now monitor water quality and provide adequate crop protection measures to insure a good yield. Water availability is affected by falling water tables, droughts and stressed by the increasing water demand of growing urban populations (Moody 1993). Likewise, local and federal governments create strict water utilization laws, limiting chemical concentrations of particular substances in surface waters throughout the nation. In addition to adhering to the aforementioned tasks, irrigators must correctly apply supplemental water such that the crop’s needs are also met without â€Å"over-application†. The primary goals of any irrigation system are to minimize deep percolation of water and replenish soil water in the root zone along the entire field (Goldhammer 1987). Thus, to achieve effective water management, an irrigator should utilize the least amount of water needed to sustain profitable yield amounts. In addition, the major concerns of managing irrigation water are controlling runoff, decreasing deep percolation, providing sufficient drainage, and limiting energy and the associated labor costs. For a small or medium sized operation with limited resources, labor and maintenance costs are important factors when selecting an irrigation system. A study conducted by Dr. Stephen H.
