Technology has improved the music industry in 3 main areas essays

Technology has improved the music industry in 3 main areas essays A certainly emerging trend in the music industry is the way technology has improved it so drastically. In the past, for instance, vinyl records were very popular and is the premium medium for music distribution because it has far more superior audio quality than its predecessor, the audio tape cassette. After a couple of years, the music industry saw its first compact disc or CD. It was a giant leap for music technology. The CD featured digitally encoded signals, far more accurate and better than the analogue vinyl. This ultimately resulted in more capabilities and diversity in music. We can see that technology has improved the music industry in three areas: instrumental, auditory and distribution advancements. The three main aspects where technology has made significant improvements are instruments, audio techniques and methodologies and music distribution and copyright. Examples of the way technology has affected the different aspects are countless. Some examples are illustrated here. Musical instruments, firstly, has been greatly influenced by technology. The early English organ, that used manual valves to control sound production is now replaced with electronic circuitry. This circuit is preprogrammed to tell the valves to release enough air to produce a certain tone. Early organs depend on how much pressure the organist applies to the keys and after much playing of the organ, the slight inaccuracies of the instrument will result in misaligned tonal sounds. Thus, the circuitry completely eliminates the need to tune the instrument regularly and ensures accurate reproduction of sound all the time. The Germany-manufactured pipe organ that sits in Singapores Esplanade arts centre, is an application of electronic technology in organs. The wind instrument is the largest and most advanced in South-East Asia (Rachel, 2004, p. 29). Computer chips that h ave been integrated into the pipe organ provides a wider r ...

How to Spot the Pegasus Constellation

How to Spot the Pegasus Constellation Stargazers looking for an easy-to-spot star pattern cant go wrong with the constellation Pegasus, the Winged Horse. Although Pegasus doesnt exactly look like a horse- more like a box with legs attached- its shape is so easily recognizable that its hard to miss. Finding Pegasus Pegasus is best spotted on dark nights beginning in late September and early October. Its not far from W-shaped Cassiopeia and lies just above Aquarius. Cygnus the Swan is not too far away, either. Look for a group of stars in the shape of a box, with several lines of stars extending out from the corners. One of those lines marks the Andromeda constellation.   Pegasus is one of three northern hemisphere autumn constellations that are easy to spot. It contains the globular cluster M14. Carolyn Collins Petersen Stargazers looking for the Andromeda Galaxy can use Pegasus as a guide. Some like to think of it as a baseball diamond, with the bright star Alpheratz as the first base mound. A batter hits a ball, runs to first base, but instead of going to second base, runs up the first base foul line until they run into the star Mirach (in Andromeda). They turn right to run into the stands, and before long, they run right into the Andromeda Galaxy.   The Story of Pegasus Pegasus the Winged Horse has a long history with stargazers. The name we use today comes from ancient Greek myths about a flying steed with mystical powers. Before the Greeks were telling tales of Pegasus, ancient Babylonian mystics called the star pattern IKU, meaning field. The ancient Chinese, meanwhile, saw the constellation as a giant black tortoise, while indigenous people of Guyana saw it as a barbecue. The Stars of Pegasus Twelve bright stars make up the outline of Pegasus, plus numerous others in the official IAU chart of the constellation. The brightest star in Pegasus is called Enif, or ÃŽ µ Pegasi. There are brighter stars than this one, such as Markab (alpha Pegasi), and of course Alpheratz. The stars that make up the Great Square of Pegasus form an unofficial pattern called an asterism. The Great Square is one of several such patterns that amateur astronomers use as they find their way around the night sky. The official IAU chart of the constellation Pegasus shows its brighter stars plus numerous others. It also shows a few deepsky objects, such as M15 and the Andromeda Galaxy. IAU/Sky Telescope   Enif, which can be seen as the muzzle of the horse, is an orange supergiant that lies nearly 700 light-years from us. It is a variable star, which means that it varies its brightness over time, mostly in an irregular pattern. Interestingly, some of the stars in Pegasus have planetary systems (called exoplanets) orbiting them. The famous 51 Pegasi (which lies on a line in the box) is a Sun-like star that was found to have planets, including a hot Jupiter.   Deep Sky Objects in Pegasus Constellation Although Pegasus is one of the largest constellations, it doesnt have a lot of easily-spotted deep-sky objects. The best object to spot is the globular cluster M15. M15 is a spherically shaped collection of stars bound together by mutual gravitational attraction. It lies just off the horses muzzle and contains stars that are at least 12 billion years old. M15 is about 33,000 light-years away from Earth and contains more than 100,000 stars. Its almost possible to see M15 with the naked eye, but only under very dark conditions. How to find the globular cluster M15. Carolyn Collins Petersen The best way to view M15 is through binoculars or a good backyard telescope.  It will look like a fuzzy smudge, but a good telescope or an image will reveal much more detail. An amateur view of M15 through a backyard-type telescope. Hunter Wilson/Wikimedia Commons The stars in M15 are so tightly packed together that even the Hubble Space Telescope, with its eye for detail, cannot make out individual stars at the core of the cluster. Currently, scientists use radio telescopes to find X-ray sources in the cluster. At least one of the sources is a so-called X-ray binary: a pair of objects that are giving off X-rays.   A Hubble Space Telscope view of the central region of globular cluster M15, which is so densely packed with stars that HST has trouble spying out individual ones. NASA/ESA/STScI Far beyond the limits of backyard telescopes, astronomers are also studying galaxy clusters in the direction of the Pegasus constellation, as well as the gravitationally-lensed object called the Einstein Cross. The Einstein Cross is an illusion formed by the gravitational influence of light from a distant quasar that passes by a galaxy cluster. The effect bends the light and ultimately causes four images of the quasar to appear. The name Einstein Cross comes from the cross-like shape of the images and the famous physicist Albert Einstein. He predicted that gravity affects space-time and that gravity could bend the path of light that passes near a massive object (or collection of objects).  That phenomenon is called a gravitational lens.

Sustainability in global business-Meeting the Challenge of Sustainable Essay

Sustainability in global business-Meeting the Challenge of Sustainable Business - Essay Example The human interactions that are pre-industrial with the natural system and the social system usually cause changes to the short-term and local scale. The present socio-ecological interactions are generating a wide spread in the global changes with changes that are temporary and far into the future. The harmful consequences that we face because of human forcing on the ecological and social systems may never find the solution required through single issues like solving the global poverty or resource efficiency (Blowfield, 2012, p. 18). The current processes and the societal structures are structured in a manner that they contribute systematically to the current directions that are unsustainable and causing the people to face the difficulty to inspire global unity around safeguarding the probabilities of the future options. The development of sustainability signifies the increase of the people’s room for maneuver. This requires an approach that is systematic in solving of problems and the strategic planning by identifying control for restoration in both ecological and human (Stoner and Wankel, 2010, p. 32). Many organizations are adopting policies and practices that are sustainable and they integrate them with the strategies in their organizations for the purpose of organization development (Schmidheiny, 1992, p. 214). Research has indicated that that most of the changes in the organizations efforts plateau after the initial period Research has of passion and was not able to become an integrated and sustained approach to the planning strategies and development. It is determined that changes that are unstained can be related to the current disclosure on the developments that are sustainable and focuses on the establishment of the evolving technology and instrumental policies such as what to do (Blowfield, 2012, p. 58).

Ethical Health Care Issues Essay Example for Free

Ethical Health Care Issues Essay According to Women’s Health Resource (2011) â€Å"breast cancer is a serious issue that will affect almost every women worldwide, either directly as someone diagnosed with cancer, or indirectly through the illness of a loved one†( Home, para. 1). In the United States breast cancer is the found in women in their early twenties and thirties. These individuals are more prone to breast cancer because she has a family history of breast cancer. In 2006, approximately 212, 920 new cases of invasive breast cancer were diagnosed in the United States (Women’s Health Resource, 2011). The case scenario below will discuss ethical and legal issues regarding a female patient with breast cancer, which refuses treatment for breast cancer. Additionally, the scenario will cover the following four ethical principles: respect for persons/autonomy, justice, beneficence, and non-maleficence that relates to the case scenario (Bishop, 2003). Case Scenario A 25-year-old female patient made an appointment with her primary care physician because she discovered a lump on her breast. She went to her appointment with her primary care physician the following day. The physician examined her breast and discovered a lump on her breast, so he made a referral for her to see an oncologist in which can diagnose her if she has breast cancer. An oncologist is a medical doctor who specializes in the diagnoses and treatment cancer (The Denise Roberts Breast Cancer Foundation, 2009). The following are the three main types of oncologist: medical oncologist, radiation oncologist, and surgical oncologist, which can practice in hospitals and research centers. The female patient can make an appointment with the oncologist in which he will inform about her condition and different types of treatments available to her in which can reduce her chance of death as well conduct a biopsy. The biopsy will determine if she has breast cancer. The ethical issues are very clear, and they are respect for autonomy and beneficence. Additionally, the legal or ethical principles involved with breast cancer are no different from any other medical  treatment/intervention. Autonomy and Informed Consent As stated by Bishop (2003), â€Å"respect for persons/autonomy is that a physician acknowledges a person’s right to make choices, to hold views, and take actions based on personal values, and beliefs† (p. 7). In order for an adult to refuse treatment, he or she must be legally and mentally capable by meeting the following criteria: 18 years or older, understands the nature of the condition, and voluntary. Additionally, parents with children under the age of 18 have the right to consent to treatment as well refusing treatment for his or her child. As recognized by Miller et al. (2000), physicians have a moral and legal obligation to comply with a patient’s voluntary, informed refusal of life sustaining treatment, regardless of a physician judgment concerning the medical or moral appropriateness of this. In the case of the 25-year-old female patient with breast cancer she rejected medical treatment and was informed by the oncologist about the terminal illness. Death is seen as failure, rather than an important part of life (Smith, 2000). A conflict can arise with the patient because of the decision she made about not receiving care, which can likely end her life. The oncologist is obligated to inform or educate the patient about breast cancer, benefits of treatments, and risks involved with no treatment. The following are treatment options for cancer patients: lumpectomy, mastectomy, chemotherapy, radiation therapy, and surgical reconstruction (Women’s Health Resource, 2011). Although a physician can suggest benefits of any type of treatment the patient has the freedom to choose if he or she wants the treatment as well as ensuring the patient understand his or her own condition. When a patient refuses treatment for breast cancer or any medical condition, the issue of autonomy becomes difficult because of the serious health consequences. The health care professional will offer the patient different options for treatment when this occurs. As stated before the physician should consult with the patient about his or her decision because nurses have ethics and codes of conduct in which he or she must follow. Nurses must care for patients while taking care of him or her as  well as respecting and supporting the patient rights to decline treatment at anytime (Stringer, 2009). Medical professionals should respect the autonomy of patient decisions because it is a critical in the health care industry. Beneficence Rosenthal (2006), the principle of beneficence means that the health care provider must promote the well-being of patients and avoid harm them. Once a patient refuses treatment the health care professional must communicate the harm associated with no treatment for his or her condition. This can play a major role in how beneficence and maleficence is judged. When a patient has breast cancer and refuses treatment there is not another alternative option for the patient. During this principle the health care professional should ensure that he or she is maximizing possible benefits for the patients and minimizing harm when dealing with treatments. The health care professional can suggest certain treatments but the patient does not have to receive any care for his or her condition. When this occurs the physician will focus on different conflict resolutions for the care as well as services. A health care professional job is to offer quality of care to the patient in which he or she will ben efit from the medical treatment. During this principle, the health care professional will act with compassion when informing the patient about the potential benefits and risks for any medical condition. A patient is reliant upon the health care professional for someone who is caring and willing to share in the responsibility as well as treating him or her with dignity and respect. The 25-year-old female does not want treatment in which makes it hard for the oncologist to provide quality of care during the consultation and care. Non-maleficence Rosenthal (2006), during this principle, the health care provider ought to strive not to inflict harm to a patient, a requirement also seen as a duty not to refrain from aiding a patient. In addition, this principle will coincide with beneficence because it is reducing the harm to any patient  although a patient refuses care/treatment. The health care professional is obligated to help the patients to the best of his or her ability by providing benefits, protecting the patient’s interest, and promoting welfare. Additionally, how, and what the health care professional does for a patient should have greater chance of benefiting the patient than harming the patient. This is done by risk benefit analyses, where the health care professional can conduct research on the condition and different medications. The health care professional should explain any side effects for treatments as well as medications that the patient will become knowledgeable about options for his or her conditio n. Justice The principle of justice means to treat others equitably, distribute benefits/burdens fairly (Bishop, 2003). In addition, it is very important for the health care professional to keep a patient informed about treatments and he or she should not provide misinformation to the patient. A major issue with this principle is economic barriers can interfere with a patient when trying to receive treatment and medication. The health care organization is required to provide services/care to a patient regardless of health care coverage, especially the uninsured In addition, the department should that all patients are treated equally regardless of age, race, and ethnicity. Additionally, this principle will focus on justice, which will provide care/treatment regardless of the patient demographics or ethical issues he or she encounters with the health care professional. During this principle, the patient is treated with dignity and respect even though he or she refused care/treatment for any medic al condition. Conclusion Refusal of care is one of the most common ethical dilemmas in the health care industry, which is often difficult to resolve when his or her well-being is threaten. The health care professional must determine, which aspects of autonomy, beneficence, justice, and non-maleficence a patient want before providing care. Administrators within a medical facility must  examine the following underlying issues: competence of a patient, the distinction between apparent, and real refusal of care (Michels, 1981). A physician has the legal duty to provide and ensure the patient with sufficient information about treatment and care when he or she is at the facility. Additionally, an ethical dilemma will exist because of a patient’s right will conflict with a physician obligation of providing quality of care to an individual. This was the case with the 25-year-old female with breast cancer. References Bishop, L. (2003). Ethics Background. Kennedy Institute of Ethics.

Maslow ¡Ã‚ ¯s hierarchy of needs theory Abraham Maslow is known for establishing the theory of a hierarchy of needs, writing that human beings are motivated by unsatisfied needs, and that certain lower needs need to be satisfied before higher needs can be satisfied. According to Maslow, there are general types of needs (physiological, safety, love, and esteem) that must be satisfied before a person can act unselfishly. He called these needs "deficiency needs." As long as we are motivated to satisfy these cravings, we are moving towards growth, toward self-actualization. Satisfying needs is healthy, blocking gratification makes us sick or evil. In other words, we are all "needs junkies" with cravings that must be satisfied and should be satisfied. Else, we become sick. A figure of Maslow ¡Ã‚ ¯s hirerarchy of needs model has shown as follows: Æ’8 ¡5 Physiological Needs Physiological needs are the very basic needs such as air, water, food, sleep, sex, etc. When these are not satisfied we may feel sickness, irritation, pain, discomfort, etc. These feelings motivate us to alleviate them as soon as possible to establish homeostasis. Once they are alleviated, we may think about other things. Æ’8 ¡5 Safety Needs Safety needs have to do with establishing stability and consistency in a chaotic world. These needs are mostly psychological in nature. We need the security of a home and family. However, if a family is dysfunction, i.e., an abusive husband, the wife cannot move to the next level because she is constantly concerned for her safety. Love and belongingness have to wait until she is no longer cringing in fear. Many in our society cry out for law and order because they do not feel safe enough to go for a walk in their neighborhood. Many people, particularly those in the inner cities, unfortunately, are stuck at this level. In addition, safety needs sometimes motivate people to be religious. Religions comfort us with the promise of a safe secure place after we die and leave the insecurity of this world. Æ’8 ¡5 Love Needs Love and belongingness are next on the ladder. Humans have a desire to belong to groups: clubs, work groups, religious groups, family, gangs, etc. We need to feel loved (non-sexual) by others, to be accepted by others. Performers appreciate applause. We need to be needed. Beer commercials, in addition to playing on sex, also often show how beer makes for camaraderie. When was the last time you saw a beer commercial with someone drinking beer alone?
