Once We Were Not - Essay Example The author suggests that fossils directs to the fact that most of successful animals shared somewhat similar biological history. But the homosapiens ability to compete and evolve has made it is single species to exist today in the world. The co – existing of different homosapiens and neanderthalensis have co –existed before but the latter has vanished from earth due to evolution.Homosapiens like Australopith form Australis, Ardipithecusramidus from Ethiopia andAustralopithecus anamensis from Kenya all have existed on earth before millions of years. The author states that these homospaiens have ape like look and were a small brained, big faced bipedal species. The remnants from different part of the world have suggested that these have co –existed and persisted before 2.2 million years. The caves in France were occupied around 11,000 years ago by homosapiens called Cro magons. They were having lineage resemblance to the homosapiens of Africa. The author claims that Neanderthalensis in Europe were also homosapiens who existed in Europe some 30,000 years ago. They were also homoerectus in Java. The author suggests that â€Å"Black Skull† found in Northern Kenya direst that homosapiens existed on earth around 2.5 million years ago. The author points out that many types of Australopith existed millions of years ago. However the longevity of these species was only a few hundred or thousand years. But African continent was home to many types of homosapiens according to author. As per ( Tattersall 1-7)â€Å"Nevertheless, even if average species longevity was only a few hundred thousand years, it is clear that from the very beginning the continent of Africa was at least periodically—and most likely continually—host to multiple kinds of hominids† The author claims that the earlyhomosapiens had a different form rather than newer ones. They shared same landscape and same continent. These hominoids have also reached China

Computer Communications & Networks - Lab Report Example What is a TCP/IP Model? Before discussing the communication in networks from the home computer to the X stream, we have to first discuss the TCP/IP model. As illustrated in the Figure 1.1, we can see the comparison of both OSI model and the TCP/IP model. The TCP/IP model is associated with Application layer, Transport layer, Internet Layer and Data link Layer. Likewise, application layer of the TCP/IP model is associated with protocols such as Simple Mail Transfer Protocol (SMTP), Hyper Text Transfer Protocol (HTTP), File Transfer Protocol (FTP) etc. The transport Layer is associated with protocols such as Transmission Control Protocol (TCP), User Datagram Protocol (UDP) etc. The Internet layer is associated with Internet Protocol (IP), Address Resolution Protocol (ARP), Internet Control Message Protocol (ICMP) and lastly, the data link layer that is also called the Network interface layer is associated with Ethernet, token ring etc. for accessing the X stream from a remote location, we will discuss the insights of these five layers of the TCP/IP model. Moreover, Figure 1 also illustrates the resemblance of each layer of TCP/IP to the OSI model. Figure 1 TCP/IP and OSI Model Image retrieved from: (Clarke, n.d) Figure 1.2, demonstrates the functionality of each layer in order to exchange data from the home computer and the X stream server. ... The network access layer than links the transmission to the required segment from the same layer as shown in Figure 1.2 Figure 1.2 Example demonstration via TCP/IP Model Protocol Layering Up till now we have discussed the TCP/IP model, protocols and functions associated with each layer. Protocol layering will demonstrate the functionality of each layer after another along with Protocol Data Units (PDU’s) and packet headers while connecting to the X stream from home computer. Considering the four layers of the TCP/IP model, we will discuss four PDU’s on each layer, as shown in Figure 2, the message initiates from the application layer four of the TCP/IP model. The four PDU’s are 1-PDU, 2-PDU, 3-PDU and 4-PDU. Figure 2 Image retrieved from (James F. Curose & Keith W. Ross, 2000) The layer 4 that is an application layer and considered as a high layer, constructs a message M that is composed of various parameters that needs to be tailored by the application criteria. Likewise, a typical packet may include parameters such as message type and associated data. The packet from the home computer is transmitted in the form of Message M to the third layer of the TCP/IP protocol stack, as shown in Figure 2. Likewise, layer three of the source (Home Computer) breaks the 4-PDU in to two separate parts as M1 and M2. Accordingly, the layer three of the source (Home Computer) integrates with the two separate parts M1 and M2 called as headers that contributes for constructing 3-PDU into two separate parts. Headers are associated with the information that is a requirement for the source and destination on the third layer for enabling services on layer four (James F. Curose & Keith W. Ross, 2000). Likewise, the development

The Users Experience of Critical Situations or Metal Psychiatric Medi Essay

The Users Experience of Critical Situations or Metal Psychiatric Medical Emergencies - Essay Example This is not quite in line with the NICE guidelines which suggest that mental health services should be provided for patients diagnosed with debilitating mental disorders that ensures that patients, and their families and carers, are well informed, cared for and supported (Nice.org.uk) There are several case studies in the literature with respect to critical situations or metal psychiatric medical emergencies. The perspective of users of the healthcare facility offered by the healthcare services is vital to gain a proper understanding of the situation. The other important aspect is the perception of palliative care and requirements of a patient suffering from a medical crisis. With respect to modern medicine, the French philosopher Descartes’s writings in the 17th century have had a very deep impact on the management of symptoms by healthcare professionals and their ways of approaching symptoms. This hence is reflected in both our perceptual understanding of them and consequently how we attempt to manage them. As mentioned earlier the principal outlook based on the philosophies of Cartesian dualism is that symptoms should be understood as aspects of a disordered biological state. The resultant trend is reflected in modern medicines approach to care which has largely been based on differentiating between physical and non-physical aspects of disease symptoms and subsequently targeting care at these physiological manifestations. However, most patients seldom if at all distinguish between the biological and perceptual symptoms, and indeed effective and appropriate acknowledgement of personal meanings of illness and its problems is a primary step to effe ctive care of sick individuals and their families ( Wenger, 1993; Halldorsdottir & Hamrin, 1996). Illness, as Pellegrino (1982) defines it, is only partially defined when understood as a physiological anomaly. The experience of sickness in psychiatric/behavioural dysfunction holistically is formed by an individual's acuity of alterations in his/her existential state and should not be ignored.  

Physical Geology Essay Example | Topics and Well Written Essays - 1750 words

Physical Geology - Essay Example The landscapes we see around us have many different and varying features, many of which have been fashioned by a number of external forces. Erosion is probably the major force in this respect and it can come from a number of sources, such as wind, water and ice. While these sources can be seen to be unique, in fact in the majority of cases they usually combine within the erosion process that shapes our landscapes. Wind is forceful creator of particular land features, especially in areas where deserts exist, normally close to the equator. In this instance as the warm air rises, forming clouds, the winds blow these away from the equator, both north and south, leaving a dryer condition. As a result, these areas receive significantly reduced rainfall, limiting the amount of vegetation, which would bind the earth’s surface together. The wind also carries particles of plants and rocks with it to create a build up of vegetation and chemical deposits in other areas. The power of the w ind, for example in the form of hurricanes, can have a significant effect on the landscape, as well as destroying human habitats.

Finance Dissertation Example | Topics and Well Written Essays - 12000 words

Finance - Dissertation Example These sorts of scandals caused several studies in which scholars and financial analyst tried to identify the content of information that the directors usually possess through which the directors were able to generate higher profits in the stock market. This paper clarifies whether directors outperform their business markets whenever they trade, when they buy, or when they sell. The research paper also establishes the characteristics in transaction level, the firm level, or the director-level, which determine the directors’ trade profitability. Based on the same, hardly any existing studies provide adequate empirical evidence of percentage gain by directors generated by directors in their process of purchasing or selling company shares. The paper also provides that directors are better selling off shares, through insider trading, rather than purchasing them at comparatively lower prices. For testing, data was extracted from the New York Stock and NASDAQ of fifty randomly select ed companies. The insider trading information of these companies for the financial period January 1, 2009 until June 30, 2012 was analyzed. The testing has proved the hypothesis that directors are able to generate abnormal profit through the insider trading sale transactions. 1.0 Introduction In the world of economics and finance, when it comes to financial malpractices, insider trading tops the list. Insider trading is one of the most notorious financial crimes being practiced by managers, directors and other employees all around the globe. An individual who has direct and reliable access to the non-public information about the security can define insider trading as the buying and selling of a security. Insider trading is not always considered as a malpractice or illegal and is subjective to the underlying intention to the transaction. The statement can be further elaborated by considering the fact that if the trader is reaping profits on the basis of such information which is not being public yet, then the insider trading transaction is illegal. In addition, insider trading does not always mean that buying and selling of security is taking place. Providing confidential information to a third party, in exchange of monetary or any other form of consideration, is also illegal. The practice of insider trading is not confined to Directors of any corporation but the practice also prevails among brokers and even the family members of the directors. Although, once the information is public, the inside transaction is not illegal as the parties involved does not derive any unfair advantage over the general public. Media has made the masses at general knowledgeable with the passage of time and they have also equipped themselves with the technicalities of insider trading especially after the cases of Enron and Martha Stewart. The Securities and Exchange Commission of USA has adopted the practice of enforcing strict and practical guidelines which distinguishes legal and illegal trading of the shares by the inside people. Insider trading is not a recent or a latest money making gimmick which has been exploited by the directors and managers to earn higher return. The history of insider trading dates back to the great depression as well. The securities and exchange commission of the United State

Hamlet Act I Essay Example for Free

Hamlet Act I Essay The first time that we are introduced to Hamlet is in Act I Scene II. It is apparent that the predominant thought in the atmosphere is the death of King Hamlet, Hamlets father. Claudius says; Though yet of Hamlet our dear brothers death the memory be green. This first introduces the Hamlet as mourning for his fathers death, setting the scene for Hamlets mood. The first time that that hamlet speaks is just after Claudius has called him his cousin and son, where Hamlet replies; A little more than kin, and less than kind. Here he is making a pun on the words kin and kind, saying how feels now too closely related to Claudius. He also says; Not so my lord, I am too much Ithsun. Here he is saying that he feels too much like Claudiuss son. Both of these show that Hamlet is quite witty, and also that he is a good listener, and picks up on other things that maybe other people dont. Hamlet feels that the wedding of his mother and Claudius is too soon after the death of his father, and he planned to go back to school, however when his mother asks him not to he says; I shall in all my best obey you madam. This shows that although he does not want to stay he will to please his mother. His displeasure at the wedding is also shown in his soliloquy at the end of the scene, where he says; She married. Oh most wicked speed, to post with such dexterity to incestuous sheets. Here he is saying how he thought she remarried too quickly and that it is like incest to marry her dead husbands brother. Although the end of the scene, as Horatio is telling Hamlet that he saw the ghost of his father, Hamlets speech becomes quite fast and abrupt, unlike the dialogue before. This shows that he has strong feelings for anything to do with his father, and wishes to see him again, even though he must be a ghost. In scene III Ophelia is talking to her brother Laertes about the move that she thinks her and hamlet share. However, Laertes thinks that it is just a whim and that Hamlet does not really love her; Forward, not permanent, sweet, not lasting. He is saying that although it may seem to Ophelia to be real, it is not and Ophelia should not believe Hamlet when he says he loves her. Polonius also reflects this view, and tells his daughter to ignore Hamlet. The entire of Act IV seems to reflect Hamlet character and mood. He has come to see the ghost, and even though this is most unnatural he has come any way. This could be because he misses his father, but also because he feels that something is rotten in the state of Denmark. He is unhappy at his mothers speedy marriage, especially to his satyr uncle. Perhaps he feels that the ghost of his father can in some way help him with this. Also he threatens to kill his friends if they do not let him go when the ghost beckons him, even though there is risk; By heaven Ill make a ghost of him that lets me. He seems to want to speak to the ghost of his father, even more than the risks of following a ghost which may be evil. In Act V, when the ghost tells Hamlet that he was murdered, yet not by whom yet, Hamlet says: I with wings as swift as meditation or the thoughts of love may sweep to my revenge. This shows that already he believes that this apparition is his father, and immediately at the thought that his was murder he says that he will exact revenge. This shows how upset he is at his fathers leaving, reflecting that he thought all along that something strange was going on. Hamlets reaction to what the ghost tells him seems to be full of emotion; Hold, hold, my heart, and you my sinews grow not instant old. This how bad he is feeling not only for the spirit of his father but also for the fact that he has just learned that his father was murdered, by his uncle, who is now king. He calls his uncle; O villain, villain, smiling damni d villain! This is because in old plays the villain was usually described as being evil but smiling pretending to be good as is Claudius. After he has spoken with the Ghost, Hamlet tells his friends not to speak of the ghost, and also to ignore him if he starts acting strangely; Nay but sweart. He makes them swear on his sword that they will not say anything. This could be because he wants to sort out the thoughts in his head first because this has been quite a big thing he has learned. Also, it may be a way in which he can plan to exact his revenge on Claudius for he cannot stand to be made to act a son to him. In conclusion, in Act I, Shakespeare sets up the introduction of the story, but also with hints as what is to come later on in the play he plays on Hamlet use of words to show his distaste for the marriage and his uncle, but also by using the ghost to tell hamlet of its fate and also hamlet pretending to be mad it implies that the rest of the play will be much centred on this, and also make us question as to whether hamlet is still pretending to be mad or whether he has actually crossed over the line to madness. Certainly there are things he does that other people consider madness, but he can also be normal. However, like where he sees Ophelia and is not properly dressed, if he loves her as he says he does it seems that he would not do these things event o her.
