Computer Network - Essay Example This would make the Wi- Fi more effective by ensuring it spreads wider field through structures and different obstructions. Organizations that profit from shopper information transfers are not excited about the thought. As indicated by the Washington Post, Verizon, Intel, AT&T, Cisco, and others have suggested that the range should be issued to organizations as opposed to being utilized in the FCCs proposed arrangement. "We imagine that the range would be most valuable to the bigger society and to broadband organization in the event that it were authorized," an Intel official says. At the same time, Google and Microsoft have have their own ideas regarding the proposition. These propositions include prompt advantage to clients, free national web access that would make a country own brilliant organized gadgets, "a huge number of gadgets that will make the advancing Internet out of things."(Lee, Yi, Chong, & Jin, 2014). Presently, the advocates of both Google and Microsoft are part of the Wireless Innovation Alliance, which is a care group for the FCCs drive.This incorporates Dell and the New America Foundation. Google stands out to be the beneficiary if more individuals begin using its administrations to browse the web over extensive free Wi-Fi systems, or make any telephone and future calls through free administrations like Google Voice or Google Hangouts. Google has suggested that free mass Wi-Fi would start a blast in development. It is obvious that this will open a door for greater budgets that will offer room for advertisements through pursuit or in other imaginative ways. Faster internet and Wi-Fi across the nation means that people will experience the best live shows on the web, through Google Hangouts, which could incorporate promotions across the nation through broadcasts over that the Internet using tablets and cell phones(Niyato & Hossain, 2007).

Work placement in Hailong Hotel Essay Example | Topics and Well Written Essays - 2250 words

Work placement in Hailong Hotel - Essay Example The rest of the floors at the hotel have guest rooms. The total number of staff working in the hotel is thirty. The hotel has four receptionists, six floor supervisors, six room attendant, one cleaner, two securities, two hostess, two accountants and one general manager (Trip Advisor, 2012). When innumerable people work together in the same organisation, it becomes quite complex for the human resource manager to manage these group of people. Therefore, the main objective of this paper is to determine an issue in Hailong Hotel and thus offer a theoretical background to the processes that is being focused on in the paper. Furthermore, the paper will also attempt to analyse that specific issue within the agency. Issues in Hailong Hotel Human resource management has attained major focus in the recent years because it contributes to overall efficacy in the organisation. If the overall success of the organisation depends upon the competence of its employees then it is significant for the o rganisation to manage them in a proper way so that the goals can be attained effectively (Yang & Cherry, 2008). The main issue that has been recognised is related to proper management of staff in the Hailong Hotel. The hotel staff requires adequate training so that they can function effectively and thus assist in attaining the goals of the organisation. Lack of training demotivates the employees to work in a proper way and thus might hamper the overall effectiveness in the hotel. Ineffective training problems generally tend to be associated with the workplace problems and thus if the hotel focuses upon improvement in the training that is rendered to the staff then it is likely to reduce problems related to understaffing and theft (Yang & Cherry, 2008). Theoretical Background to the Issues Being Identified Even though the hospitality industry identifies the fact that institutions from where they are recruiting their human resources are performing well, there are numerous concerns. Th ere are many hotels that are offering poor and inconsistent training and also train the wrong kind of people in order to attain a training subsidy. It can be mentioned that training must be attached with additional retention policies (Zhang & Wu, 2004). It is vital for an organisation to create a form of career structure as well as career development through which the industry can endeavour to modernise the recruitment as well as training methods. The hotel industry must offer its staff with the opportunity to progress professionally by means of studies and training, traineeships and apprenticeships (Whitelaw & et. al., 2009). Hospitality industry is one within which the customers are continuously overwhelmed within the hospitality in the way in which they are treated. It is a known fact that if the staff are provided with the quality training then in such circumstances it can enhance the motivation and their performance. Furthermore, the turnover rate of the staff might reduce as w ell (Valachis & et. al., 1995). It is quite difficult to be a part of the hotel industry especially in terms of management position. Different types of people tend to visit the hotels daily. Understanding this diverse group of people is also a cumbersome task for the management of the hotels. Diversity related training can mean a lot of factors. Training can focus simply upon the comprehension of cultures of numerous identifying groups and recreating a person’s biases, prejudices as well as stereotypes. Diversity training can be more focused upon the skills to assist the staff to learn a

Problems and Parallels - Essay Example The species homo erectus was almost human, because it was an advanced hominid which walked upright on two legs. This species disappeared 230,000 years ago and was replaced by homo sapiens. The word sapiens comes from Latin and means â€Å"knowing† and it refers to the larger brain size and greater intelligence of homo sapiens. Humans share a large percentage of their genes with apes and chimpanzees but their larger brain size and differences in the physical structure of their hands and their speaking organs make it easier for humans to adapt and learn new skills like tool use and language. Quite a lot of the social behaviors of humans and apes are similar and some chimpanzees have even been taught to speak sign language, and so the overlap is perhaps bigger than we might expect just by looking at the hairy bodies of other primates. 2. It was once thought that Neanderthals with their larger body size and heavier skulls were an earlier form of humanoid but scholars now accept that they are part of the same species as homo sapiens and probably interbred with the more slender form of human that we resemble today. Archeologists have discovered that the two species overlapped in time by many thousands of years, and it may be that the higher intelligence and better adaptability of anatomically modern humans gradually squeezed the Neanderthals to the edges of the known world until they died out. Homo florensiensis skeletons found just a few years ago have set the scientists rethinking the whole definition of homo sapiens because these tiny 1 meter tall pygmy like people have some similarities with older forms of hominid, and yet apart from their reduced size, seem also very similar to modern humans. They, too, seem to have co-existed with modern humans in the same area at the same time, and may have lasted until about 12,000 years ago, which is longer than the

Role of Spirituality in Patients with Sickle Cell Disease Essay Example for Free

Role of Spirituality in Patients with Sickle Cell Disease Essay Spirituality, as defined in this article entitled Role of Spirituality in Patients with Sickle Cell Disease, is the capacity to rise above life experiences, to celebrate life, and to experience joy. Spirituality is comprised of acceptance, the need for love, mercifulness, and self-fulfillment and it applies to all mankind; on the other hand, being religious is relative to the person’s religious group and its practices (Cooper-Effa, et al. , 2001). They have divided a person’s spiritual well-being into involving a religious component or a relationship with God and an existential component, which involves the individual’s sense of life purpose. It was concluded in this study that those patients with a relatively high existential component were able to cope up more with the pain and the over-all outcome of the disease. It has been known that spirituality can increase the ability to tolerate pain (cited in Landis, 1996). This concept can be applied by getting the patient’s cooperation and trust, and then the nurse will facilitate a talk about spirituality. This will empower the patient to establish his spirituality and the nurse will also be able to develop closer ties with the patient, improving rapport. The nurse can further help the patient by getting him a spiritual counselor, as per patient’s request. By helping the patient strengthen his spirituality, an improvement in the patient’s over-all outlook on the disease, on life, and a probability of lesser pain may take place. Holistic practice in nursing is very important nowadays. As a nurse, there are several skills that should be present to help client’s achievement of spiritual needs. The nurse should be open to all kinds of religion and beliefs, he must try to maintain open minded. He or she should respect these beliefs and religious practices by not questioning the nature of these and by participating in these activities whenever the client wishes the nurse to. Also, nurses cannot let their own beliefs take over them. If there are circumstances wherein the nurse finds that he is unable to accept a client’s belief or practice, then it would be best for the nurse to ask for help from another nurse discreetly. Patience, understanding, and wisdom are needed for a successful patient and nurse interaction. References Journal of the American Board of Family Practice. (2001).

History of Atomic Theory

History of Atomic Theory The atomic theory is developed since 2000 years ago the Greek philosopher Democritus proposed that there was a limit to how small one could be divide matter, this smallest matter indivisible particle was called atom. However this atomic theory of Democritus was criticized by Aristotle who proposed a model based on four basic elements of earth, air, fire and water. Aristotles view held for the next 2000 years as it better suited religious beliefs of the time. In 1801, an English teacher named John Dalton proposed his atomic theory which stated matter is composed of all small indivisible atoms, elements contain one type of atom; different elements contain different atoms, compounds contain more than one type of atom. In 1904, British physicist J.J Thomson and others demonstrated that cathode rays (electrons) were present in all matter. Thomson proposed that the atom was a sphere of positive charge in which embedded were rings of negative charges (electrons) , like plums in a pudding. Lather on, in 19 century, the discoveries of radiation leads to a new progress of Physics. We knew that certain elements emitting radiation, this suggested that atoms are no longer indivisible and not indestructible, as proposed in Daltons atomic model. Radiation provides an important tool for the study of matter. In 1911, Rutherford first suggested the use of alpha particles to probe the internal structure of the atom. Finally, the nucleus and its protons were discovered. Rutherfords scattering experiment Ernest Rutherford, directed an experiment to Hans Geiger and Ernest Marsden in 1909, in which the newly discovered alpha particles (Helium nuclei) were fired at a thin gold foil layer which only a few atom thick. At that time the atom was thought to be analogous plum pudding by Thomson with a negative charge (the plum) throughout the positive sphere (the pudding). Most of the alpha particle passed through with no or only very small deflections in a vacuum (see figure), as would been excepted on the Thomson model of the atom current at the time. About 1 in 8000 was deflected through angles greater than 90 degree. The result was so unexpected that Rutherford was very unexpected that Rutherford was promoted to write†¦.it was almost incredible as if you fired a 15 inch shell at a piece of tissue and it came back and hit you. Therefore Rutherford concluded that majority of the mass of the atom was concentrated in the nucleus. The small size of the nucleus explained the small number of the alpha particles that were repelled each other in this way. Rutherford showed that the size of the nucleus was less than about 10 -14m. Bohrs model, how it fit experimental observation Accelerated electrons emitted and lose energy which predicted by Predicted by Maxwell and confirmed by Hertz, however the electron doesnt spin into the nucleus because of energy losing. Later on, In 1903.H.G.J Morseley found simple, regular relationship between the frequencies of X-ray emission line, thus it provided an evidence to support Bohrs model. Scientist began to work on an alternating model to replace it. Bohrs postulates In 1913 the Danish physicist Niels Bohr (1885~1992), put forward some radical propositions to account for the discrepancies between Rutherfords model of the atom and the available experimental evidence. Bohrs postulates are 1. Electron can remove in certain allowed orbitsstationary states (energy) without radiating energy. 2.when an electron falls from a higher energy level to a lower energy level, it emits energy that is quantised by the plank relationship E2 E 1= hf. 3. Augular momentum (mvr) is quantised and can only take values of the nh / 2Ï€ when n is the principal quantum number. The first postulate account for the stability of the atom. However why the these stationary state excited was unknown. They exist was a fact. The second postulate explains the line emission spectra. Emission (or absorption) of Energy is discontinuous and corresponds to a transition between two stationary states. Since the energy can be quantized, the emission, the frequency of the emitted (or absorbed) radiation is predetermined. A transition between different states will lead to difference frequencies or colours. The third postulate effectively sets limits on the radius of the allowed orbits. Bohrs model Bohr realised that if his model was correct, each atom would have a spectral fingerprint to the differences between electron energy level in that atom. The Rydberg equation which also known as Balmer equation, has given him evidence for the quantised emission of the energy from hydrogen atom, leading him to going on to further his model and define his postulate. So the hydrogen spectrum was very significant to the development of Bohrs model of the atom, because without the understanding of it, Bohr may not continue his work of the model. Produced and observable when hydrogen gas was excited by the addition of energy. The equation in the original form was modified by Rhydberg until it worked and could be applied to explain the spectrum of hydrogen by using integer values of n, only as suggested by Bohr in his postulates. Quantum number and quantum changes Its possible to determine the energy of each orbit using Bohrs model and from this construct an energy level Figure for hydrogen. The figure below shows the energy these energy levels. Alternatively a transition between stationary states can be show in figure. B. The Balmer series of lines occurs when the electrons fall to the n=2 level from n=2 level n=3,4,5 and 6 levels. This is illustrated differently in figure. B. How Bohr describes the hydrogen spectra Bohrs model of the atom wad quite similar to that of Rutherfords with two important differences firstly, it assisted positions to the electrons, but secondly the electron energy level s were quantised. This was radically new, the idea that electrons had energy states and could absorb and emit energy to change states, and had no evidence. Bohr realised that if his model was correct, each atom would have a spectral fingerprint to the differences between electron energy level in that atom. The Rydberg equation provided him evidence for the quantised emission of the energy from hydrogen atom. It leads him to going on to further his model and defines his postulate. So the hydrogen spectrum was important to the development of Bohrs model of the atom. The energy levels describe by Bohr is clearly marked. According to Bohr, the Balmer series (shown on the bottom of the diagram as the hydrogen spectrum) was cause by changing energy levels, in the process releasing light. As shown, larger energy changes produce more energetic photons, as seen in Balmers series, as further, this diagram shows how the Balmer series is formed by successive electron transition to the 2ndshell (transition to other shell produce additional lines named after their discoveries.) This is a great achievement that the Bohr s model is able to provide a physical basis for the Balmer series formula. From his second postulate E f Ei= hf. (i) states for initial energy level (f)states for final energy level Ei=1/ni2E1and Ef=1/nf2E1 hence: hf =1/ nf2E1-1/ ni2E1=(1/ nf2-1/ ni2) E1 And since c=fA=>A=c/f the expression reduces to 1/A=E1/hcX(1/ nf2-1/ ni2) where R states for Rydbergs constant, RH(hydrogen)1.097X 107m-1. By using the mixture of classical physics and quantum physics, Bohr was able to define the equation for the spectral lines of hydrogen. He didnt know why the electrons obeyed his rules. These were purely empirical results. Problems with the model For all the success, the Bohr model of the atom had serious limitations: It and ad hoc mixture of classical and quantum physics; it allows some laws of the classical physics held and others did not. Hydrogen has only one electron, and Bohrs postulate are only able to explain it. It cant work fo r multi-electron atoms. It could not explain the relative intensities of the spectral line; some lines were more intense to the others and it was not known why this should occur. Certain spectral line were foun of a number of very fine and close lines and the cause of these hyperfine spectral lines could not be explained. The splitting of spectral lines when the sample was placed in a magnetic field (called the Zeeman effect, and discussed below) could also not be explained. The postulates faced a problem that it is suited for larger atom. Hydrogen is the simplest atom containing only one electron. Similarity He+and Li+have one electron. Bohrs model works with theses atom and ions. In all the other atoms however the electron interact with each other. In a larger atoms the outer electrons are shielded from the nucleus by the inner electrons. Interaction between electrons also result in different energy levels. The affect Bohrs model to the extent that the spectra of multiple electrons could not be explain. When the spectrum of the hydrogen was examined it was noted that the emission line varied in intensity. Some were quite intense and others were less intense; some were sharp and some were boarder. The following figure. illustrate these differences. Bohrs model could not explain these features but later it was explained that electron orbited in a ellipse and not in a circles. As the developing of the light spectroscopes improved it was found that some of the spectral lines were made up with hyperfine lines. This suggestion spitted Bohrs energy level theory; however there was no explanation for this. The Zeeman Effect Zeeman Effect occurred when a magnetic field us pass through a discharge tube. The magnetic field increased the hyperfine splitting of spectral lines, further breaking them up. As the limitation, Bohrs model was unable to explain the experimental evidence. In 1896 a Dutch physics Pieter Zeeman (1865-1943) found that when he placed a source of sodium light between the poles of a strong magnet the lines split into three or more. This could not explain by Bohrs model, The spectral line of some elements can even split to 15 lines. This is called the anomalous Zeeman effect. It cant be explain by that time, and it leads to the new developing of the model to explain it. This begin with the work of de Broglie. The following is the formal definition of Zeeman Effect: The splitting of single spectral lines of an emission or absorption spectrum of a substance into three or more components when the substance is placed in a magnetic field. The effect occurs when several electron orbits in the same shell, which normally have the same energy level, have different energies due to their different orientations in the magnetic field. A normal Zeeman Effectis observed when a spectral line of an atom splits into three lines under a magnetic field. Astronomers can use the Zeeman Effect to measure magnetic fields of stars. The following diagrams shows the normal spectral line and the Zeeman effect. References Textbooks 1. Excell HSC physics by Neville Warren published in 2007 2.

Essay on Portrait of the Artist as A Young Man and The Wall

The Artist in Joyce's A Portrait of the Artist as A Young Man and Pink Floyd's The Wall      Ã‚  Ã‚   Foragers, the people who live in hunter-gatherer societies, have no artists. It is only when society becomes complex enough to support a division of labor do artists emerge-first as shamans, then as the painters, singers, writers, etc., that we usually think of today. Society, then, creates the artist, but it can also destroy him. In A Portrait of the Artist as A Young Man, James Joyce describes the particular development of Stephan Dedalus that led to his becoming an artist. Pink's development in Pink Floyd's The Wall, mirrors that of Stephen yet concludes in the destruction of the artist.    An important similarity between them is their isolation. Joyce believed that the separation from society is important for an artist in order to see society clearly. Common people are easily swayed by authority figures, as Dante and other Irish Catholics are against Parnell by the church's condemnation, or by other trendy movements such as the peace testimonial, all of which are rejected by Stephen in the end. When Stephen in his discourse on beauty describes the basket, he says "your mind first of all separates the basket from the rest of the visible universe which is not the basket. The first phase of apprehension is a bounding line drawn about the object to be apprehended" (212). Thus, by extension, if an artist is to apprehend the society, a line must be bound around society separating the artist from it in order to view it; it is difficult in a maze of hedges to comprehend the pattern, but when viewed from above the paths in and out become clear. The artist must stand outside the changeable mindset of the average human being in orde... ...at make up the crowd or the eerie, bulbous faces on the train. Stephen fulfils his role as an artist by becoming a sort of teacher-shaman as he gives his discourses on esthetics to Lynch and prepares to depart into the world, like some wandering monk or sage. Separate from society he is able to search out and convey the truth of society. Pink's isolation, however, utterly destroys him. Unable to endure, the wall is torn down by the hammer of conformity and Pink becomes the very personification of repressive society. If the role of the artist is to objectively show society the truth of itself, then Pink emerges an artwork in himself, an accurate mirror of the forces that shaped him.       Works Cited    Joyce, James.
