The idea of changes in the composition of a popula Essays - Biology

The idea of changes in the composition of a population being attributable to changes in its environment has been an extremely useful. With this perspective, we can coherently account for the distribution of forms in the fossil record, for example. However, great interest also lies in speciation , which occurs when populations that for some reason cease to interbreed become different enough to lose all ability to interbreed. (In actual life, the boundaries between species are not always absolute varieties only gradually evolve into species, after all and it has been found that occasional fertile crosses between closely simi lar species do occur.) The rule-of-thumb of fertile offspring as defining species remains the way most biologists think of it, but the possible exceptions have generated complexities in classifica tion and in modeling gene flow. A p opulation split in half by a n un crossable barrier c an over time develop huge differences between its two parts. The most famous example of this process, called "allopatric" "different country" speciation, is the squirrels of the Grand Canyon, who have diverged into different species on the two sides of the Canyon. But w hen the genotype of a single, inbreeding population changes gradually over time, at what point should we say it has turned into a new species? Our "rule of thumb" about producing fertile offspring can hardly be applied to two different points in the history of the same population. And yet if the differences between early and late specimens are substantial, can we be confident in calling them the same species? As an intellectual matter, it is difficult to know when one continuously changing population should be regarded as a different species from its remote ance stors. As a practical matter, it is also difficult to know how specimens available for study are actually related to each other anyway. If two fossil snake teeth look similar, but neither looks exactly like any modern snake, were they separate species, or were they merely two slightly different variants of the same species? And is either of them ancestral to any modern snake? Many specialists in prehistoric life paleontologists tend to assume that speciation occurs relatively easily when plant or animal communities are separated, and they argue that the default assumption should be that two specimens should be assumed to be different species until they can be convincingly shown to be the same (which is hard to demonstrate with extinct forms). Others argue that speciation is in fact relatively difficult. Barring intervention with atomic bombardment, we have not succeeded in changing a genotype sufficiently to make it a whole new species just through selective breeding alone. (That is why all dogs are still the same species.) The best assumption when looking at prehistoric forms should therefore be that two similar specimens should be considered to belong to the same species until shown to have more variation between them than is exhibited in a modern population of similar animals, if there is one. All of this becomes particularly controversial in the case of proto-humans. Darwin did not explore the evolution of humans indeed only one clearly pre-human hominid fossil had been discovered when he published The Origin of Species Through Natural Selection in 1859. Since humans look a lot like modern Great Apes, it seemed logical that we should have a common ancestor with them, but that was about as much as one could say. In some respects, the exact ways in which we draw the lines among species may not make much difference. The more we learn about genetics, the more obvious it becomes that what matters most is not the label given to a form, but our understanding of the over-all process of evolutionary transformation that is continually going on. Geneticists are ever refining more detailed "family trees" of biological forms based on the inheritance of specific gene mutations . In these family trees, it makes no significant difference where one species stops and the next begins. What matters is where mutations occur that are inherited by future generations.

Sleep Cycle Essays

Sleep Cycle Essays Sleep Cycle Essay Sleep Cycle Essay Its natural to blame sleep problems on stress or physical changes that come with age. But many cases of either sleeplessness or poor sleep are caused by a handful of specific problems, most of them fixable with lifestyle changes or the help of a doctor. Here, five little-known causes of sleep problems and what to do about them. 1. Light How it disrupts sleep: You probably already know that when you stay up late under bright lights, you interrupt your bodys natural sleep-wake cycle, because light tricks your brain into remaining in daylight mode. Less well known is that the light from computer screens and iPads shining directly into your eyes at close range is especially troublesome. Why? Part of the problem is that the light from these devices is at the blue end of the spectrum, which scientists believe is particularly disruptive to circadian rhythms. Blue light, although common during the day, doesnt occur naturally during the evening. Similarly, light shining in your eyes while you sleep even very small amounts coming from, say, a lighted clock makes your brain think its morning and emerge out of deep sleep. Darkness triggers production of the hormone melatonin, the hormone that triggers sleepiness and the onset of sleep. Light prevents this release or shuts it off. The evidence: Studies have long shown that shift workers and those who work late at night have poorer sleep and higher incidences of certain conditions associated with lack of sleep than those who regularly sleep eight or nine hours at night. A recent study published in Cancer Causes amp; Control, for example, found that the countries generating the most light at night have the highest incidence of breast cancer. And studies at the Light Research Center at Thomas Jefferson University in Philadelphia have found that the use of computers, lighted readers, and TVs at close range is tied to a higher incidence of sleeplessness. Whos at risk: Everyone exposed to light shortly before bed or during sleep. Light is also bad for hearts, which need deep sleep to recharge. Surprising fact: Every year theres a spike in the number of heart attacks just after the start of daylight savings time in the spring. What to do: Dim the lights and turn off all lighted screens at least an hour before bed. If you use a reading light, make sure its not any brighter than necessary and doesnt shine in your eyes. Do a light police room check: Are there streetlights outside your windows? Use blackout curtains or shades and make sure they fit the windows tightly so no light seeps in around the edge. Charge laptops, phones, cameras, and other devices in another room. Use an alarm clock without a lighted dial, or turn it to face the wall. Keep a flashlight next to your bed and use it whenever you have to get up to use the bathroom or let the dog out and be careful to point it away from yourself so you dont look into the beam. Dont turn on an overhead light, and never use nightlights. If you must use a laptop, turn down the screen brightness as low as you can tolerate and prop the laptop as far away from you as your typing arms will reach. If you love eReaders, try a Kindle or other device with a screen thats not backlit. 2. Pain How it disrupts sleep: Just about any kind of pain signals sent by the brain jaw pain, headaches, back pain, or arthritis, for example disrupt sleep, lifting you from the deep, restful REM cycle into lighter sleep or causing you to sleep fitfully and partially wake up over and over, which experts call microarousals. The evidence: Surveys of chronic pain sufferers reveal that between 60 and 90 percent sleep poorly. But many dont realize that their pain is the cause of their poor sleep. This can become a vicious cycle, says Thomas Roth of the Sleep Disorders and Research Center at the Henry Ford Hospital in Detroit, because even partial sleep disruptions can increase sensitivity to pain. In other words, even mild pain causes poor sleep, which in turn leads to more pain. Whos at risk: Anyone who suffers chronically painful conditions such as arthritis, back or neck pain, jaw alignment problems, dental pain, fibromyalgia, headaches, or any other type of chronic pain. Note: The p ain doesnt need to be severe; studies show that even mild pain disrupts sleep. According to Roth, frequent microarousals can occur throughout the night without your being aware of them. The result is that you never attain deep REM cycle sleep and wake up feeling tired and grumpy, but you dont know why. What to do: Take steps to treat your pain proactively. Using over-the-counter pain relief is a start, but its always best to consult with a doctor and develop a comprehensive pain-relief program. For example, you may need physical therapy to combat back and neck pain, or migraine medication if your frequent headaches might be migraines. If bruxism (teeth grinding) or jaw clenching is leading to jaw pain, a mouth guard is often the solution. 3. Disrupted breathing How it disrupts sleep: When oxygen flow to the brain is interrupted, your brain sends a warning signal that wakes you up either fully or partially, causing fitful sleep or preventing deep, restful sleep. The result: You wake feeling like you didnt sleep well, even if you were out for nine hours straight. The best known version of this is apnea, which is a complete stoppage of breathing. A much more common and less recognized problem is upper airway resistance syndrome, or UARS. In UARS, structural blockages somewhere in the airway nasal congestion, your tongue falling back and blocking the back of the throat, or just having a smaller airway to begin with begin to interfere with the flow of air. What happens is that you wake up over and over again without knowing it, but the sleep interruptions last only a few seconds, too short to be detected by a standard sleep apnea test. The evidence: Even subtle levels of restricted breathing can lead to deep brain stimulation and arousals that prevent your ability to stay in deep sleep, says otolaryngologist Steven Park, an otolaryngologist and author of Sleep, Interrupted: A Physician Reveals the #1 Reason Why So Many of Us Are Sick and Tired. You dont realize youre waking up, but your brain wakes up, so its now in a light sleep. We see people who are waking up 100 times a night. Whos at risk: People who breathe through their mouths or have chronic congestion, such as from asthma or allergies. If you sleep more poorly on your back, this can be a sign of UARS, because when you sleep on your back your tongue is more likely to sink back and block the entrance to your throat. If you have a narrow face, a thin neck, or had extensive orthodontic work to correct a crowded jaw, youre likely to be at particular risk for UARS, says Park. What to do: Start with some self-tests. Try using pillows to keep yourself on your side, or put a tennis ball in the back pocket of pajama bottoms, so you cant sleep on your back. If your nose often feels stuffed up, you might find relief with breathing strips, available at the drugstore. Another option is to try is a device designed to hold the nostrils open; brand names include Nozovent and Breathe with Eez. A saline nasal spray works for many people. If you have congestion due to seasonal allergies, try an antihistamine. (But if you take one that can act as a stimulant, such as Claritin or Sudafed, dont take it too close to bedtime. ) If none of these help, ask your doctor to refer you to an ear, nose, and throat (ENT) specialist, who can evaluate whether youre a candidate for Continuous Positive Airway Pressure (CPAP), a nasal mask that delivers air directly through your airways. An ENT can also determine whether tongue position is causing your UARS, in which case a dental device that pushes the jaw and tongue forward can help. For many people, losing a few pounds can be the ticket to better sleep, since excess weight is linked to all kinds of breathing problems, including UARS, snoring, and sleep apnea. 4. Medications How they disrupt sleep: Medications sometimes have side effects that trigger sleeplessness or interfere with deep sleep. Most common culprits: asthma medications, corticosteroids, blood pressure medications, and antidepressants. Also, many ingredients in common medications act as stimulants. They may cause jitteriness during the day and trigger sleeplessness or prevent deep sleep at night. Example: Bronchodilators like albuterol and salmeterol, commonly used to treat asthma, bronchitis, and COPD, can amp you up and interfere with sleep, yet patients are often directed to use them at the end of the day. Other common medications that can interfere with sleep include SSRIs, such as Prozac and Paxil, and beta-blockers taken for high blood pressure and heart disease. Sometimes medications sabotage your sleep indirectly. Diuretics, for example, can interfere with sleep by causing you to use the bathroom at night. Tagamet (generic name cimetidine), taken to control reflux and ulcers, can cause sleeplessness, especially when combined with caffeine or other medications. Like many side effects, sleeplessness from medications can affect some people but not others; Propecia, used to treat hair loss, and the antihistamine loratadine (brand name Claritin) are both known to cause sleeplessness in a percentage of those who take them. Some people react to opioid pain medications with rebound sleeplessness, feeling sleepy at first but then waking up and being unable to get back to sleep. The evidence: Although every medication is tested for side effects during the FDA approval process, in many cases evidence of side effects mounts over time as a drug enters more widespread use. Albuterol has been widely reported to cause restlessness, nervousness, and sleeplessness. An article in the European Journal of Clinical Pharmacology also found that beta-blockers interfere with melatonin release. Recent studies have found that Prozac, Zoloft, Celexa, and other SSRIs affect sleep in a significant number of patients. If youre using an antidepressant, be sure to talk to your psychiatrist about any possible sleep problems and ask about alternative antidepressants if this is an issue. Whos at risk: Those taking regular medication for a chronic condition such as asthma, depression, high blood pressure, or pain. A medication that you take once is less likely to cause an ongoing sleep issue because you take it for a short period of time and are more likely to notice the side effect. When you have a chronic condition, youre more likely to attribute any sleep problems to the condition rather than the treatment. What to do: Any time youre prescribed a new medication, ask the doctor to discuss in detail all side effects you should be alert to. Its always a good idea to ask both the doctor and the pharmacist, How will this medication affect my sleep? Because some medications cause sleepiness, some interfere with sleep, and some do both, asking the question in an open-ended way will get you the most information. 5. Depression How it disrupts sleep: Fatigue is one of the most prevalent symptoms of depression, yet many people dont realize how closely related depression and poor sleep can be. Depression wreaks havoc with your natural biological rhythms; many people with depression have trouble getting out of bed in the morning, and they oversleep or get fatigued and nap during the day. Yet their sleep is fitful and of poor quality, so despite spending more hours ostensibly sleeping or trying to sleep, they dont feel well rested. Then at night, depression sufferers often have trouble maintaining a regular bedtime routine. Having slept late in the morning or napped late in the day, they may not feel sleepy. Anxiety, which often accompanies depression, may cause excessive late-night worry that contributes to sleeplessness. The evidence: Because the relationship between depression and insomnia is a chicken-and-egg cycle, experts have studied it from both directions. Psychological studies have found that a high proportion of those with depression suffer from either sleeplessness or disrupted sleep, and a recent study by the University of Maryland found that 40 to 60 percent of people

Addiction Research Proposal Example | Topics and Well Written Essays - 1500 words

Addiction - Research Proposal Example The problem of gambling is bigger than the individual, social group or a community. Understanding and preventing it, is therefore important for the society as well as for the country. Before one can write about gambling, one must understand the nature of its addiction. Addiction according to Henderson is "a complicated condition, with biological, physiological, psychological, behavioral and spiritual aspects. For this reason it is best to think of...addiction as multifaceted disorders, only one of which is the compulsive use of the addicting substance." (3) Individuals who are addicted (whether to alcohol, drugs, gambling or sex etc.) demonstrate particular behavior such as loss of control over the behavior, and continue to engage in the addiction despite negative consequences (Henderson 4). From a behavioral perspective addiction according to the DSM-IV (Diagnostic and Statistical Manual, 4th Edition) can be defined as an abuse or dependency which has negative consequences and interferes with important obligations, and causes noticeable distress or significant impairment in functioning. The criteria for dependence also include those that indicate physiological dependence as well as a loss of control as evidenced b repeated unsuccessful attempts to quit or cut down." (Henderson 6). Gambling, according to Collins, is a sequence of activities which involve two or more parties willing to place at risk something of value known as the stakes. They engage in this activity in the hope of wining some of greater value called the prize. The winner or loser is determined by the outcome of events that is known as the result. Gambling by definition does not make the gambler addict. This is because it is essentially a game in which the participants may undertake the activities commercially or in private situations (Collins 15). Gambling is an addiction for some people. Addicted gamblers tend to be

Digging Deeper - Research Paper Example During his teenage, Mendelssohn was already a high-ranking musical composer although most of his works never reached the public domain. He received various invites to attend different concerts in Berlin and Zurich from where he got a chance to practice his work. At the age of fifteen, Mendelssohn was a full-grown musician and he had already written his first symphony. His musical genius was later exhibited when he wrote his first string octet using E-flat. Like other romantic era musicians, his music sought to tell the deep feelings and secrets of humanity. However, Mendelssohn maintained the conservative tone of classical music throughout his work. The conservative nature of his work is what separated his from the adventurous artists of romantic era such as Hector Berlioz, Franz Liszt and Richard Wanger. His work included symphonies, piano music, chamber music and oratorios. His most celebrated symphony is A Midsummer Night’s Dream. Felix composed the symphony following Shakespeare’s request. The song featured in the Shakespeare’s play A Midsummer Night’s Dream. The Hebrides is his second most celebrated work of art. Felix first performed this song to Queen Victoria and Prince Albert in 1829 at their palace. Felix Mendelssohn lived and talked music up to his death in 1847. Your post on Nikolai Rimsky-Korsakov is significant to the discussion and timely. The post is also unique since it deals with Russian romantic era music. This is significant to the discussion since most post have focused on European music. The post has also analyzed the song by considering its rhythm and some other important features of style. Although your post has contributed significantly to the discussion, there are few areas that you need to consider. Firstly, the post has overemphasized on your emotional attachment the song. The post has also left out essential information

Different types of economic systems Capitalism (market economy) Capitalism is an economic system in which the means of production are privately owned and the firms mainly target profits, in competitive markets. it is known as market economy because it is seek to maximize satisfaction or profit through own decision regarding consumption or production. Characteristics all resources are owned by individuals The decisions about the allocation of those resources are made by individuals without government intervention No significant economic role for government is necessary. The concept of supply and demand plays a role in determining the pricing structure A market economy encourages competition. The U.S. is most commonly example for market economy which had many provisions that facilitated and protected the market economys characteristics.. Advantages: The market gives producers an incentive to produce goods that consumers want. The market provides an incentive to acquire useful skills. The price system encourages producers and consumers to conserve scarce resources. Disadvantages (1) A private market economy may be quite unstable (unemployment, inflation, growth) (2) Business may simply satisfy the wants they have created through advertising. (3) Prices may affect to the consumers (4) Markets just do not work in some areas such as public goods, and national defense Socialism (command economy) Characteristics The government creates a central economic plan for all sectors and regions of the country. The government allocates all resources according to the central plan. The goal is to use the nations capital, labor and natural resources in the most effective way possible The central plan sets the priorities for production of all goods and services. The goal is to supply enough food, housing and other basics to meet the needs of everyone in the country. Cuba, North Korea, China, Russia and Iran are the most commonly examples of command economies. Russias Go plan has been the most studied. It was also the longest running, lasting from the 1930s until the late 1980s. Advantages The govt. Will ensure a more equal distribution of income and wealth Essential goods/services will be provided to the community The govt. Can determine which goods are produced. 1. There is little consumer choice. 2. Little variety of goods and services 3. Loss of individual freedom 4. Leads to allocate and productive inefficiency 5. Subsidies on essential goods and services quickly lead to shortages. Mixed economy A mixed economy is an economic system that incorporates aspects of more than one economic system. This kind of economic system has both privately-owned and state-owned enterprises or that combines elements of capitalism and socialism, economic systems. Characteristics private sector business activity encouraged. taxes used to collect revenue to pay for state goods and services. The government also provides services such as education, health, military defense, legal and infrastructure to society. The government plays an important role in resolving economic problems faced by society advantages less inequality of income because intent of government is to have a balanced economic growth of an economy. allows individuals to run their business and make profits Goods and services are produced to benefit the society rather then to benefit the economy. Fiscal policy Fiscal policy is the use of taxes and government spending to control the economic activity of a country.the government uses this policy to continue, Economic growth Price stability Full employment Expansionary fiscal policy Before the government spending increase and before the tax rate reduction or both GDP is low because the price level of the economy is low.

In the curve shifted to the left (Ms1 to Ms2) Fiscal policy impact to the Vodafone UK Because of the UK statutory tax rate reduced to 26%, effective from 1 April 2011 and the impact on the year end tax balances. EBITDA increased by 8.0% with the EBITDA margin increasing by 0.7 percentage points, reflecting higher service revenue. A shareholder in the Company who is an individual resident for UK tax purposes in the United Kingdom is entitled, in calculating their liability to UK income tax, to a tax credit on cash dividends we pay on our shares and the tax credit is equal to one-ninth of the cash dividend. The tax free allowance all income earners are allowed to earn an amount of income before they start to pay tax., the personal tax free allowance in the UK for 2011-2012 was  £7,475. Monetary policy impact to the Vodafone UK According to the Vodafone annual report, 45.9bn revenue performs in 2011 and it is 3.2% growth in compared with 2010. It is because the UK government expands the monetary policy by buying Bonds from people and it caused to money supply increased. People has more money to spend on Vodafone services and products there for the demand of the mobile customers are increased by 14.5% to 370.9 m. International trade The economic interaction among different nations involving the exchange of goods and services, that is, exports and imports. The guiding principle of international trade is comparative advantage, which indicates that every country, no matter their level of development, can find something that it can produce cheaper than another country. As a multi national company, Vodafone Global Enterprise manages the communication needs of over 560 of our largest multinational corporate customers. It provides a range of managed services which bring together every aspect of a customers telecommunications infrastructure, both fixed and mobile,(Annual report Vodafone group-2011) Advantages by international trade for Vodafone Quality of the product has been increased because of high competition with foreign businesses Having an open economy Growth of high technologically methods using by Vodafone group Increased company reputation world wide Market share has been increased Disadvantages smart phones and the tablet market begins to take off. markets remain competitive and the economic environment, particularly across southern Europe, is challenging. Foreign Industry regulators continue to impose lower mobile termination rates and lower roaming prices. The combination of competition and regulatory pressures. Increase prices of the Vodafone products because of tariffs. Emerging markets Definition The term emerging markets is commonly used to describe an economy with a GDP per capita substantially below the advanced world average and typically with a growth potential above the global average. According to the World Banks definition an emerging markets country has a Gross National Income (GNI) per capita less than approximately USD 9,000.(growing markets) The most exciting emerging markets are, BRICs( Brazil, Russia, India, China), Mexico, South Africa, Clombia, Hungary, Indonesia, Turkey, Poland, Malaysia,Chile,peru, Thailand. Barriers to entering emerging markets for UK businesses Differences in language and culture are important barriers to entering fast-growing markets like the BRICs. Global trade has always been vital to the UK UK firms looking to export for the first time continue to face too many barriers that put them at a competitive disadvantage to their overseas competitors. capital is drives many businesses to take on the risks of doing business in emerging markets. Considering about the success of Vodafones in emerging markets, The number of customers using mobile services in emerging markets such as India and Africa has grown rapidly over the last ten years, increasing by over 17 times, compared to nearly 130% in more mature markets such as Europe. increased revenue market share in India and Turkey. Approximately 75% of mobile customers are in emerging markets such as India and China. EU crisis This week BCC met with a delegation from APEX, the Brazilian trade and investment promotion agency. It is clear that there are vast opportunities in the country, as indeed there are in the other emerging markets, which UK firms are yet to take full advantage of. BCCs latest research confirms that the EU remains the most popular destination for UK exports. Just under half of Chamber exporters see the large and faster-growing BRIC economies of Brazil, Russia, India and China as the best prospective markets for increasing business over the next twelve months. Unfortunately, exporters to the fast-growing BRIC markets are the most likely to encounter barriers that hold back sales.

What are the primary perils of and salutary remedies for political power? Political power has been an issue plaguing man since the beginning of politics itself. How to gain it, how to hold it, how to properly use it, how to exploit it. Throughout time power has been exercised by those that hold it over those that do not. As with anything, problems are sure to arise. These problems call for solutions if peace is to be restored. The primary perils of political power are a strong desire to keep it, a devotion to anything other than justice, an unwillingness to stand for the right thing, and ruling in a merciless manner. The remedies of political power can be (but are not limited to) confidence that laws are just, a willingness to negotiate, the sharing of power, and staying strong in what is just and right. The first problem (or peril) of power is that those who posses it do not in any way wish to give it up. King stated that â€Å"Lamentably, it is an historic fact that privileged groups seldom give up their privileges voluntarily.† (King 68) This often causes a lack of willingness to negotiate with others. Mandela says of the white in South Africa â€Å"Whites had the highest standards in the world-and aimed to keep it that way.† (Mandela 367) There would be no negotiating on the part of the whites. They simply refused to assume the risk of losing what they held. â€Å"Creon will not listen to Antigone, nor does he listen to anyone else but his own inner demons.† (Mandela 456) By not listening to another, Creon threw negotiation by the wayside, which not only aided the corruption of his power, but ultimately lead to his demise. Even when negotiations are made, they must be acted upon, not simply spoken. The fact that King a... ... the devotion to agendas other than justice, the rejection of standing up for the right thing and no mercy are problems King and Mandela address. To remedy4hese perils, the two men suggest that those in power be sure that their laws are just, be willing to negotiate and share their power, and have the spirit to stand strong for what is just and right. Though a single problem can weigh down political power, no one solution can solve it. It must be a combination of these and/or many more in order to solve the true perils of political power. The truth is, when something it so highly desired, so highly revered such as political power, corruption lurks behind every corner. It is up to those in charge (as well as those that influence them to be sure that this power is not corrupted, not abused. This is the preservation of politics; this is the preservation of justice.
