Neolithic Vs Paleolithic

Life changed dramatically between the Paleolithic and Neolithic times. Paleolithic is the early phase of the Stone Age, lasting about 2. 5 million years, when primitive stone implements were used. The Paleolithic Period was also called the Old Stone Age. Neolithic is the later part of the Stone Age, when ground or polished stone weapons and implements prevailed. The Neolithic Period was also called the New Stone Age. The Neolithic Revolution was the world's first traditionally, provable revolution in agriculture.It involved the wide-scale change of many human cultures from a lifestyle of hunting and gathering to agriculture as well as settlement, which supported larger population. Important events significantly changed the way of life between Paleolithic and Neolithic times. Although life changed dramatically between these two times there are still some similarities and differences amongst them. Paleolithic and Neolithic times have a lot of things in common. Both of these times were dependent on natural resources. In Paleolithic times they moved with food supply.In Neolithic times they used need water and good soil for crops. Paleolithic and Neolithic both had a government. In Paleolithic times the males ruled the families. In Neolithic times there was a Chief with council. Both of Paleolithic and Neolithic times had a religion. They had religions, which meant they believe in life after death. Socially in both time period’s men hunted and farmed and women gathered. Neolithic and Paleolithic periods had technology. For Paleolithic they used stone tools, and in Neolithic they had farming, baking and firing pottery, specialized tools, and bronze tools and weapons.Both Paleolithic and Neolithic evolved. As found in Document 2 during Paleolithic times the Ice Age forced man to move and change. Mankind was forced to depend less on plants and animals. In Neolithic they farmed allowing them to settle in one place, which gave them time to develop settlements and new trades. Also both of these periods had accomplishments. In the Paleolithic Age they developed language, controlled fire and made and used tools. In the Neolithic Age they accomplished making the wheel, and farming.Although there are many similarities between Paleolithic and Neolithic times there are still several difference between them as well. One difference is that Paleolithic is the Old Stone Age and Neolithic the new Stone Age. Another difference that is found in Document 1, was that Paleolithic tools were used for hunting; they were heavy and basic whereas, Neolithic tools were used for clearing land and farming; they where sharper, lighter, more variety, and polished. The main difference between these â€Å"tool kits† is the purpose they were used for.Paleolithic man was a nomad, food gatherer, and a hunter. Neolithic men settled as found in Document 3. The people were agriculturist, who domesticate animals, and grew a variety of crops. The houses of Paleolithic ma n were skin tents or caves. The houses of Neolithic man were made of mud, wood and thatch. The Paleolithic and Neolithic Ages also have differences in the form of artwork. As found in the Document 4 the Paleolithic Age they had cave paintings showing the hunting of a larger animal and the danger of hunting. As found in Document 5 the Neolithic Age they domesticated plants and animals.In the Paleolithic Era, plants were used for medicines and food. Animals were used for hunting. However, in the Neolithic Era, plants were used for food in the New Stone Age, however, the difference was that plants were grown on farms. Animals were used for domestication as well as other purposes. Document 5 also displays another difference between the Paleolithic Era and Neolithic Era. Their artworks are very different from one another. In the Paleolithic Era they had paintings of cows, and they had small portable art. Their art is also represented by cave wall drawings.In the Neolithic Era they had me galiths and 3-D art. They were represented by structures and sculptures. These different artworks show change between Paleolithic and Neolithic times. The Neolithic Era was more advanced because based on their artwork it seemed they were harder to build, more complex and took more time. The diets of these two periods were also different. The Paleolithic man consisted of meat, fruits, berries and wild grain. Neolithic man had dairy products like milk, cheese, meat and grains like wheat, barley and rice.The clothing for Paleolithic man was made of animal skins and leaves, while Neolithic man made clothes of cotton wool. In the Paleolithic age there was no specialized occupation. As found in Document 3, in Neolithic age there was division of labor, and some specialization occupations so that that there was more variation of crafts like carpentry, weaving and pottery. In Document 6 it shows that the Neolithic architecture was different then Paleolithic architecture because the Neolithic architecture had settlements and villages while the Paleolithic architecture did not.Finally due to the invention of agriculture, farming and the wheel in the New Stone Age there where many revolutionary changes and progress that came upon man’s life, which was nonexistent in the Old Stone Age. In both Paleolithic and Neolithic times there were many events that helped change their way of life. If it weren’t for those events, today would not have been the same. For example the Paleolithic people invented fire. The fire helped the Paleolithic people move into colder regions, protected them animals, and helped them with their cook their food.The Neolithic people invented weaving, pottery, metalworking, and the wheel. They also discovered agriculture. Because of agriculture people can now farm instead of hunting and gathering. This permitted and allowed people to settle down and live in one place, which led to settlements. Because people settled they now lived closer to o ther, this allowed them to start using communication. This later developed into language. Also past experiences have led up to the structure of the Neolithic house. For example in Document 6, it says how discarded items, such as bits of pottery, were pilled around each house.This was to keep harsh North Sea winds from blowing through the stonewall through small gaps. This is an example of experience. Document 2 shows how the Ice Age changed the way of living, especially hunting. Because of the Ice Age it forced man to depend less on plants and more on animals. This event caused man to make adaptations to survive. All in all important events significantly changed the way of life between Paleolithic and Neolithic times. Even though these two time periods were very far apart and had a dramatic change in life these two times still have similarities and differences amongst them.There were similarities in government, religion, social, technology, and evolution. There were differences in a rchitecture, diets, artwork, tools, dwellings, clothes and lifestyle. The events in the Paleolithic Era led up to the Neolithic Revolution. The Neolithic Revolution was the transformation that reformed people from being hunter gathers into being farmers. Because of the Neolithic Revolution, our world is the way it is. Both Eras had different drives and commitments to strive, but at the end of the day they’re foremost objective and aim was to survive.

Coming Of Age Personal Essay Essay

Everybody experiences coming of age in their lifetime. Coming of age is the transition from childhood to adulthood. My coming of age started in the middle of my grade 8 year and has continued up until the present. So, for me coming of age has occurred from grades 8-10. The three steps that really defined my coming of age was my traveling to Europe, starting high school and getting my first job at Tim Horton’s. My first step in my coming of age was traveling to Europe with my aunt and uncle. Firstly, I was not with my parents which made me feel more self-reliant. This was my first time riding on a plane and traveling for more than a week without my parent so at the time it seemed like a big deal. I felt that because I was not being watched over as heavily, I was more responsible and was growing up. Secondly, I was starting to travel the world for the first time and it made me think of my future. It reminded me that when I was old enough, there were going to be endless possibilities to what I could accomplish and where I could go. This is definitely an important step in growing up. Realizing that you need to start preparing for your future and start to figure out what you want to do and where you want to go. Lastly, I made new older friends that made me feel like I was growing up and expanding my â€Å"bubble†. The people I met were older then I was and were so friendly. I felt more m ature around them. Meeting new people if all part of â€Å"coming of age†. This is why traveling to Europe was the first step for me to start maturing and to start coming of age. The second step I took towards my coming of age was when I started attending high school at Sir William Mulock Secondary School. Starting high school was a big change from elementary because there was a lot more responsibility. The teachers do not come after you for late assignments and there is a lot more homework that is necessary to complete. This helped me prepare myself for after high school when my employers will need me to show initiative when completing tasks. So therefore, this was a big step in my coming of age. Secondly, when you are in high school, authorities start to treat you as a mature young adult. This means that they have fast paced learning environments and expect you to show up for class. If you miss to many classes you will not pass the course. This taught me to push myself when I was tired or sick which is a big part of growing up. When you are an adult working full time, you can’t skip work when you aren’t feeling well. So for these reasons, starting high school was a big step in my coming of age. The last and most recent step towards my coming of age was starting my part time job at Tim Horton’s. Having this job as my first job was a big responsibility. In order to keep my job I had to show up on time, manage my extracurricular activities and homework around working, ask a lot of questions and deal with co-workers. This added responsibility helped me to start to understand what working will be like once I have graduated high school. Thinking ahead for the future and obtaining responsibility is part of coming of age. Also, for this job I had to learn many new skills. When you are starting a new job there are many techniques you have yet to master such as operating the cash register and making food/beverages as well as customer service skills. Learning all of this helped to me feel more mature and useful. Lastly, the job provided me with a steady flow of cash. Earning money was something that I had never experienced before and it gave me a good feeling. It made me self-r eliant , which is a big part of growing up. Having my own money and being able to spend it on what I want is also a test to see if I can make good decisions or not as well as teaching me money management. This is an important skill for when I have moved out. Therefore , getting my own job was the most recent step in my coming of age. So for these reason, I think that my coming of age happened over my grade 8-10 years. I am not done growing up yet, but the main events leading up to this day that have started my coming of age were my traveling to Europe, starting high school and getting my first job. There will be many more events in my future that will continue my coming of age in the future, but for now I am young and am excited for the growing that I still have to do.

Thomas Edison Essay Example | Topics and Well Written Essays - 1500 words

Thomas Edison - Essay Example Edison started schooling, however, he was not a good student at all. In fact, his teachers complained about his slow learning. Edison’s mother was so upset that she decided to teach Edison at home and hence that was the end of Edison’s school life. However, Edison was a very inquisitive child who wanted to know almost everything. His young mind was always full of awe, fascination, and questions. His mother taught him to quench his own thirst for knowledge with the help of books and Edison followed her advice and started reading voraciously to seek answers to his questions. It was at this early age that he set up his lab and started experimenting by referring to books that he read (Edison Papers). In fact, this period of Edison’s life has a great deal to offer. Today, we rely so much on school and educational institutions to become educated however Edison through his life shows us that what schools give us is nothing but a â€Å"degree† or a â€Å"report c ard† but schools are not the measure of what our minds are capable of. In spite of being exempted from formal education, Edison was determined to learn and understand. Simply attending school or giving exams cannot make us intelligent, they are nothing but mere supports.If an individual is determined to learn and seek knowledge and succeed in life, he need not depend on degrees and exams to make him eligible to do so. Determination and passion are enough for success.Edison’s life had not been a smooth run at all, especially during his growing years.

'The normal course of COPD is punctuated by increasing frequency and Essay

'The normal course of COPD is punctuated by increasing frequency and severity of exacerbations - Essay Example Exacerbation is a serious health condition that could lead to the loss of lung normal functions. (Prince et al., 2004) For this reason, patients that are experiencing exacerbations may be hospitalized and need to go through a long period of recovery. For the purpose of this study, the researcher will determine and discuss the significance of exacerbations of COPD in terms of its effect on the patients and the health care service providers. With regards to the proper management of exacerbations, the researcher will highlight the available pharmacological and non-pharmacological options for exacerbations. Exacerbations in patients with COPD are usually associated with a major decline in the long-term quality of the patients’ life and their lung functioning. (Donaldson et al., 2002; Seemungal et al., 1998) Although the etiology and mechanisms behind a severe COPD exacerbations are not clear, several studies have shown that infections caused by bacteria (White, Gompertz, Stockley, 2003; Sethi and Murphy, 2001) and virus (Rohde et al., 2003; Seemungal and Wedzicha, 2003) are present during an increase frequency of exacerbations. Exacerbations related to COPD are often associated with the increase in airway inflammation related to eosinophilia (Fujimoto et al., 2005; Zhu et al., 2001), neutrophilic (Aaron et al., 2001; Stockley et al., 2000; Sethi et al., 2000), and neutrophils in bronchial biopsies (Qiu et al., 2003). These factors may contribute to the patient’s dyspnea or difficulty in breathing. In line with this matter, it has been reported that roughly 25% of COPD patients have reported having experienced a profound total body pain. (Lynn et al., 2000) Due to the fact that most of patients with severe COPD may experience exacerbations, some patients may experience anxiety due to their functional limitations and hunger for air.

Eric Owen Moss Samitaur Tower Culver City, California Essay - 1

Eric Owen Moss Samitaur Tower Culver City, California - Essay Example ome to terms with something that vehemently challenges the status quo, giving way to forms and features that defy preconceived notions and set views about the relationship between functionality and form. It would not be wrong to say that ‘Samitaur Tower’ in Culver City is an apt representative of the typically Californian constructivism, which accomplishes, energizes and animates the surrounding landscape with its bold defiance, almost naà ¯ve and innocent tendency to challenge set notions and the innate tendency to redefine architecture by going for the possible and phantasmagoric permutations and combinations resulting out of the interplay between form and functionality. Of course, it would be totally simplistic to say that ‘Samitaur Tower’ is merely an information tower located at one corner of Hayden Avenue and National Boulevard, near the primary entry point to the redeveloped section of Culver City (Anderton 29). In fact, ‘Samitaur Tower’ is much more than this (Anderton 29). It is not merely a landmark representing the entry into a newer section of the Culver City, but rather boldly and somewhat audaciously represents entry into a new era of modern architecture, where an architectural innovation supersedes over all the requirements of form, functionality, environment and even user. The Tower marks an initiation of the era where the form, functionality, landscape and the end user stand subservient to a marvel of abstraction that though being under control, leaves no stone unturned to project an image of defiance, rebelliousness and one-upmanship. An architectural wonder that though in its very essentials intends to serv e a set and preconceived function, somehow manages to explode in the yearning to give way to something that is much more than mere functionality. In that context the ‘Samitaur Tower’ could be interpreted as being the extreme of something both good and bad, a beautiful building signifying the unrestrained expression of Id, and

Web Server Hacking Research Paper Example | Topics and Well Written Essays - 2000 words

Web Server Hacking - Research Paper Example To add to the attraction and profitability of these hacking attacks is the proliferation of insecure web applications (Zachary, 2006). These attacks on computer systems with negative intent are not new. They go as far back as the eighties when hackers used their skills to break into computer systems and perform their illegal activities. The advent of web based applications, though, has led to the increase of sophistication in hacking attacks. The skill required to perform these attacks, on the other hand has lessened proportionately. In order to understand the need for security in one’s computer system, he or she should realize the risks involved. Most operating systems have a default configuration that is not designed with security as the chief focus. The default setup, instead, focus on functionality, communications and usability. There is therefore a need to understand the server vulnerabilities in a system in order to perform particular functions to improve security (Leyde n, 2002). It is hence clear that web server hacking is an important topic that should be evaluated in detail and understood by users of computer systems. When one tries to break into or use a computer system wrongly, he or she is considered an intruder. ‘Using wrongly’ is not a restricted term and can be used to represent an act of stealing confidential information or a minor offense of just misusing one’s email for spam (Zachary, 2006). Presently, more people both through the internet and corporate intranets are continuously attempting to test the various systems’ security. The motive differs in every instance but revenge and stealing for profit are some of the motives driving intruders. ‘Hacker’ and ‘attacker’ are the two terms that are used in describing a person who tries to get into networks and systems. An individual that likes to get into their computer system

History of modern social thought Essay Example | Topics and Well Written Essays - 2500 words

History of modern social thought - Essay Example Bentham was born in February 15, 1748 in Spitalfields, London. He was part of a wealthy Tory family whose proclivity is in the practice of law. His childhood was filled with a mixture of religious superstition, owing to his mother's side, and enlightened rationalism, as his father and grandfather were both attorneys (Internet Encyclopedia of Philosophy). With such a brilliant mind, Bentham was considered as a child prodigy. At an early age, he was found sitting at his father's desk reading a multi-volume of English history and studying Latin. He attended the Westminster School and Queen's College, Oxford, where he completed his Bachelor's degree (1763) and Master's degree (1766). ("West's Encyclopedia of American Law) Bentham's father believed that his son would one day become the Lord Chancellor of England ("UCL Bentham Project"). With this, Bentham was educated as a lawyer and admitted to the bar in 1769. However, he decided against the practice of law as he became disconcerted with the complexity of the English legal code. Instead, he opted to pursue a career in legal, political and social reform. ("West's Encyclopedia of American Law) In light of his chosen career path, Bentham devoted most of his life to writing matters pertaining to legal reforms. He spent most of his time studying as he wrote for eight to twelve hours daily (Harrison). His father's death in 1792 resulted in Bentham's financial independence. With his inheritance, he lived quietly in Westminster of 40 years and generated about ten to twenty pages of manuscript per day. ("UCL Bentham Project") Ironically, he made little effort to publish these manuscripts. Such that shortly before his death on June 6, 1832, John Bowring, his secretary, remarked that from no modern writer had so much been stolen without acknowledgment. (Kahn) Cultural Context of Bentham's Works Bentham lived during the period of massive social, political and economic change. His reflections on existing institutions covered the Industrial Revolution, the rise of the middle class and the revolution in France and America among others. His passion for tackling essential reforms in view of these events was sparked by his disillusionment with the law. After attending the lectures delivered by Sir William Blackstone, the leading authority in law at that time, Bentham became deeply frustrated with the English law. As such, he dedicated much of his life in criticizing the prevailing laws and proposing reforms to enhance the system. As one of the so called "philosophic radicals," Bentham believed that much of the social problems prevailing in England in the late 18th to early 19th century were attributable to the legal system, which was not adoptive of the societal changes and economic system, which was controlled by a landed gentry that was against modern capitalist institutions. ( "Internet Encyclopedia of Philosophy") It was also during Bentham's times that England was in the midst of an aggravated state of affairs highly influenced by the Anglican Church. The country was depicted as a puritanical world wherein implemented doctrines encouraged women subjugation and prejudices, and went against natural philosophy. Given these,

Higher Education Essay Example | Topics and Well Written Essays - 1000 words

Higher Education - Essay Example transferring knowledge, skills and cultural values to the students, higher education teachers are indirectly keeping young and unemployed individuals off the streets (Stephens & Leach, 1998, p. 203). In general, each of the school teacher(s) have different set of multiple roles which they need to satisfy on a daily basis. Because of their unique function within an educational institution, functionalists may sometimes conclude that the presence of certain school policies and institutions can be dysfunctional for most of the teachers within a given educational institution. As explained by Appelrouth and Edles (2008, p. 386), the occurrence of dysfunctionality is possible because â€Å"they are functional for a more powerful social group or the social system itself†. Functionalists strongly suggest that the main function of higher education teachers is to provide better occupational opportunities for the unemployed students in the long-run. Upon analyzing the functionalist theory of education, it is the students who function as the receiver of the transferred knowledge, skills and cultural values from the school teachers. However, this theory is not applicable when it comes to analyzing the relationship between teachers and students in higher education. Conflict Theory Conflict theory view education as something that â€Å"reflects other inequalities within a given society† (Andersen & Taylor, 2011, p. 348). Because of the presence of racial, class and gender discrimination, not all students are able to receive equal rights to education. Furthermore, conflict perspective in higher education also suggest that the process of tracking down teachers’ ability to deliver good quality teaching based on the prescribed school curriculum also contributes to the development of... This essay stresses that based on symbolic interaction theory, social interaction between teachers and students within an educational institution is possible and necessary when it comes to individual and group successes. As compared to functionalist theory, symbolic interaction theory view human beings within a given society as something that is â€Å"not an established structure but as individuals who are trying to meet their life conditions and expectations†. Based on the core perspectives in contemporary sociological theory, the concept of a structural functionalism is more on the non-rational collective side whereas the orientation of symbolic interaction theory is more on non-rational and individualistic side. Considering the fact that symbolic interaction theory heavily relies on the actions made by the school teachers and students, this particular theory can be more effective and applicable in terms of analyzing how the relationship between the school teachers and stude nts in higher education work. This report makes a conclusion that as compared to functionalist and conflict theories, symbolic interactionism theory is the best applicable theory when it comes to analyzing the relationship between teachers and students in higher education. Unlike the functionalist and conflict theories in sociology, symbolic interactionism theory does not focus on analyzing the structure or functionality or conflicts in a given educational institution but only with regards to how each of the stakeholders who are trying to meet their life conditions and expectations as human beings.

Humanities Essay Example | Topics and Well Written Essays - 1250 words - 2

Humanities - Essay Example For both of them responsibility is fidelity and commitment to the truth as it presents or reveals itself to their awareness or memory at the present moment. To be responsible to truth is to encounter it/respond to it for what it is. Hamlet first manifested it in his adamant refusal to shed the outward trappings of mourning against the protestation of his uncle king and queen mother, who wanted him to express the jubilation of their new marriage. Stubborn as he is in his fidelity and sense of responsibility towards his deceased king father, he insisted in the truth of â€Å"that within which passeth show† (Shakespeare, Act 1, Scene II). As for Phaedra, when pressed by Oeneoneas to the cause of her depression, she made a simple acknowledgement of the truth raging within her: â€Å"I feel all the furies of desire†. (Racine, Act 1 Scene III). No matter how fearsome the truth is, she shrinks not in acknowledging and recognizing its potent poison. Both of them yielded to the power of this truth but differ in the manner of their response. Hamlet refused to hide the truth; Phaedra chose to languish in secret till she could bear no more to hide the truth. To be responsible to truth is to act so that that the truth comes to light, no matter what the price. When the deceased king’s apparition revealed to Hamlet the dastardly act of murder committed by his uncle against his father and commanded him to execute vengeance, Hamlet subsequently manifested a prolonged ambivalence towards acting on the revelation. Far from fear of the challenge, Hamlet’s tarrying was rather a strong proof of his commitment and responsibility for truth. His words: â€Å"prompted to my revenge by heaven and hell,† (Shakespeare, Act III, Scene I) belied his confidence in the apparition’s revelation and could not commit himself to such unverified disclosure. He, however, was committed to ascertain the truthfulness of the apparition’s revelation,

This also distinguished him from many other game designers was that, he never exactly played video games when in young age, spending more time on other activities. One of the works accomplished by Miyamoto was as mentioned earlier, Mario. This famous and loved character is depicted as a plumber, revealed in an interview with the Game Hunters in New York, that Mario wasn’t originally a plumber. Mario (Right) Luigi (Left) Miyamoto begins to state that the technology back then was not as advanced as today and also not as much room to apply the details needed. Due to the limited size of the screen, he was only able to design a character with a big nose and moustache. The back ground was a construction site; therefore Mario was made into a carpenter. In 1983, the game had a character named Luigi and the game stage was set underground, thus the decision to make Mario a plumber instead. A statue of Mario in a game shop, indicating how popular the character designed by Miyamoto has become Another moderated design that was applied to the small character was the red hat. Miyamoto reveals that this was to the efficiency of the technology available back then, the red hat was purposefully placed on the character to avoid having to animate the hair, drawing the eyebrows. The addition made the process and designing more easy and convenient. A question asked was that, if Miyamoto was Japanese, then why were the brothers (Mario and Luigi) Italian? The game designer finally replies that, ever since young age, he was a boy who was interested in foreign comics. Thus, this can be implied that his childhood memoirs influenced his design. A design philosophy conveyed in his designs is to give balance and equality to two factors. The two factors are the sense of familiarity and the new features within a game. As well as challenging the player, without until to the extent of forcing them to their absolute limit. This is an important philosophy for Miyamoto. The current design trend is the Nintendo 3Ds, and due to the works of Miyamoto, Nintendo has evolved and become more popular. As the game has become world-wide and most well-known in the Nintendo district. Some even believe that Nintendo depends too much upon the Japanese designer.

Biometric Applications for Information Security

Biometric Applications for Information Security Chapter 1 1 .0 Introduction In recent times, the use of computer towards accessing information has increased and this has made our lives simplified in different ways, whereby easing people around the globe to communicate and share information. Due to this growing computer technology, the need for an improved network service which involves public accessing these devices is to be put in place. Generally, this advancement in knowledge towards the use of modernised technology has lead to the investigating and unveiling of new threats to computer system security which affects the todays organisations. From my research carried out it has been noticed that most organisations are in search of better means of improving their information security system, and also a cost effective means towards safeguards against fraud and impersonation .As we all know that data protection is a valuable resource which must be kept strictly, controlled and managed properly in an organisation. In the nutshell, the term security basically referred to as the protection and guidance of a system from unauthorised access, be it intentional or accidentally, irrespective of the service provided by the database management system. This work will generally involve the use of keystroke dynamics as a means of establishing a unique identity, which will be used as an additional measure towards enhancing information/data security in an organisation (e.g. Banks, Institutions, legislative departments, finance houses, production firms etc). This unique identity will help present a safeguard towards authenticating the acces s to computers by recognizing an individual based on his stored features i.e. mouse movement, keyboard application, typing rhythm etc. The protection of an information database system at all level in an organisational system, has over the years become an essential concern, this is as a result of different type of threats and unauthorised advances made by malicious individuals. Many organisations, over the years gone ahead towards the development and adoption of a stronger web-based services of computer controls, because from my research I gathered that information and transaction worth fortunes are been dealt with on a daily basis and the organisation has to ensure its protection by all means. Because any breach of security will lead to fatal destruction of the system. During my report it was noticed that in most organisational application, the access to information database system where usually restricted through the use of a login ID/password protection scheme. This has been in place for years and if by any means this scheme is breached, and then the organisations information is generally exposed towards any possi ble fraudulent misuse. During my research work I gathered that, hardware based security managed systems has a positive impact towards the reduction of unauthorised access by imposter. According to â€Å"David Zhang and Anil Jain† 2006, in there book â€Å"Advance biometric† it stated that acceptance rate is still study dependent and the results indicate that the false acceptance ratio (FAR) is still on the order of 5%, beyond the acceptable risk level of many organizations, considering the costs in terms of hardware and training time. In the nutshell it will be said that security and database plays an important role in all areas where computers are used, including business, electronic commerce, engineering, medicine, law, library science and many lot of more fields. I would like to give a brief definition of what database is all about and its surrounding topics on which we will deal with as we proceed on the project work. Generally, database can be said to be a cart where information are stored, updated and retrieved, it is a very important part of everyday life, and has to be secured from utterances. The term Biometric said to be gotten from the combination of the Greek words ‘Bios, which means life, and ‘Metrikos which is said to be measuring. This technology is said to be the ability to identify an individual based on their unique characteristic, which can either be physiologically (passive) or behavioural (active) characteristic mode of identification. Over the years it has been notice that one of the most secured and effective means of authenticating and identifying an individual involves the verification of their personal unique characteristic. This is sometimes usually done in conjunction with a PIN or token (known as multi-factor authentication) also by users name and password. One of the proper ways of managing biometric secured information database includes its registration, storage, and verification which is known as â€Å"Biometric Identity Management†. However, from research Information security is known to be one of the fastest growing areas in the IT world, and its efficiency is to be assured by minimising exposure to external and internal attacker. â€Å"Enhancing information security using keystroke dynamics (Behavioural Biometrics) as an additional measure in organisations† as my research topic was brought to light. This research report is basically aimed at reviewing information database security system and the use of keystroke biometric towards security enhancement, where by reviewing the effective implementation, design and management of information system in organisation, and protecting it from intruder. Also it will clearly highlight on the pros and cons of traditional means compared to biometrics means of application. I will strictly focus on keystroke biometrics, which is a human behavioural biometric whereby need for any form of physiological attribute, is not needed. This study (Information security and biometric application) will be place into the following stages: (Nanavati. S, (2002), Von Solms S.H (2000)) Identification and authentication An individual been identified and authenticated; Authorisation Being authorised to use certain resources; Confidentiality Ensuring confidential information i.e. data or software, stays confidential and accessible only to authorised individuals; Integrity Making sure only authorised individuals can change the content of data or software; Non-denial Ensuring that an individual cannot deny the authorisation of a transaction (e.g. in Banks), like changing the content of data. The deployment of Biometrics and the above stages will require a solid understanding of the technology and why it is been deployed, its mode of function, performance and accuracy will be looked into and analysed. Also the choice of which biometric application to use depends highly on the intended application of the system, here are some of the biometric applications in existence today: finger print; face recognition, hand geometry and iris recognition etc. Some of these biometric features are applied in areas like, time and attendance systems, voters registration, immigration and border control, access control, computer security, and financial firms. This project research work will involve a practical part of the application and to achieve the aims successfully, the following objective will be put into consideration. Objectives: Presenting details of biometric applications for information security purposes. Comprehensive review on information security threat, breaches, awareness solutions and discussing case studies on its effect on organisational system. Building / implementing a keystroke access database application. Critically analyse and evaluate the impact of the design keystroke enable database(Pros and Cons) To conclude on findings and recommendation for future developments of information security system. 1.1 Why the Study and Goals The scope of this study is to present, review and analyse problems which are been faced in organisations information security, where by been able to create and suggest a means of securing sensitive information from external sources and mostly internal sources. In recent times from information gathered it has been found that most security breaches /threat in organisations have been linked to internal sources. Here I will recommend a keystroke biometric application in organisations which are known to have a friendly environment between member of staff and the easy of sharing personal details, are on the high side. Generally I am not saying there are no securities measures in organisations to curb these intrusions, but as earlier mentioned most of these leakages are carried out by internal sources. But most organisations make use of traditional login process (user names and password, chip and pin). Alternatives to password-based authentication, keystroke biometric can either be used as an additional measure or replace the traditional method, this can help identify intruded and access are denied. A special focus will be on keystroke dynamics, in which firstly, the goal is to verbalize requirements which these alternative authentication schemes need to satisfy. After reviewing the alternative methods from a security and usability point of view, the result should be to answer the question whether the presented schemes is capable of being alternatives to password-based authentication mechanisms or not. 1.2 Related Studies. In the past and at present a lot of studies and researches is been carried out, in regards to users identification, verification and authentication, with their respective ways of securing information system. Keystroke dynamics was first introduced in the early 1980s as a method for identifying the individuality of a given sequence of characters entered through a traditional computer keyboard (R. Gaines, W. Lisowski, S. ). Keystroke dynamics originated from studies of the typing patterns exhibited by users when entering text into a computer using a standard keyboard. Researches in this field focused on the keystroke pattern in terms of keystroke duration and keystroke latencies. Evidence from preliminary studies indicated that typing patterns were sufficiently unique and easily distinguishable from one another, much like a persons written signature (R. Gaines, W. Lisowski, S., R. Joyce and G. Gupta ).Here are some studies which have been carried out towards information security such a s that conducted by â€Å"Arwa Al-Hussain (2008)†, â€Å"Biometric-based Authentication Security†, â€Å"Saleh Bleha†, â€Å"Charles Slivinsky†, and â€Å"Bassam Hussein†: â€Å"Computer-access security systems using keystroke dynamics†, â€Å"R. Joyce and G. Gupta†: User authorization based on keystroke latencies. And also â€Å"Revett, K. and Khan, A†, 2005, carried out a research on Enhancing login security using keystroke hardening and keyboard griddling. But In my research work I will look into all aspect of biometric applications in regards to keystroke dynamic application and it suitability towards detecting intruders trying to gain access into a database information system. 1.3 Problem Statement In this research which is to attempt the implementation of keystroke biometric and mouse application as a security measures towards preventing the gaining of access to sensitive data from unauthorised individual in organisation, also to prevent password sharing and identity theft from within and outside the organisation. To be able to achieve this, I will be looking into the different types of biometrics and the added advantage presented by keystroke biometrics in relation to cost and easy of application. Finally I will not neglect the difficulties that may be encountered towards the successful achievement and completion of this research, also all necessary steps will be taken to have a conclusive project work. 1.4 Outline of Dissertation Topics and Organisation The other part of this paper work is organised and subdivided in the following pattern. Chapter 2 will focus more on the in-depth of Biometrics application, the benefits of biometrics compared to traditional authentication methods, advantages and disadvantages of the different identification mechanism ,it challenges and effect on todays society and finally the different types of biometrics. Chapter 3 will concentrate on the information security issues, social engineering and security solutions presented by biometrics enhanced system. In Chapter 4 an in-depth analysis of the keystroke biometrics will be look into and its application towards information security. Chapter 5 will concentrate mainly on implementation of keystroke biometrics, a demonstration of its design application and functions, towards security enhancement and also user acceptability survey on the application mode will be analysed. Finally in chapter 6 I will conclude on findings and recommendation for future developme nts of information security system. Chapter 2: 2.0 Introduction: From my research it has been gathered that access to most organisation‘s computer systems which content various information are done by using authentication and identification means. The commonly used security approach towards identification and authentication is by â€Å"login process†, which involves the users ID and password. This has been in use for years towards the verification of a person trying to gain access to a computer information system. This mode of security approach has over the years been a big problem to most organisations security management system, as a result where workers could routinely share passwords with one another, sometimes forgetting their passwords or stored them in places which they could be easily seen by other people. This has lead to the level of security breaches, threats and fraudulent transaction increasing to a disturbing state, due to this the need for highly secure identification and personal verification technologies is being sear ched for. From researches carried out it has been found that biometric authentication can solve some of these problems, whereby help in reducing this growing security threat to a minimal level. Another importance of biometrics is its ability to improve the usability of a system since the person in use does not need to remember his or her passwords when trying to gain access to the information system. Biometrics as we know is not a new discovery to the world at large this has been in existence, during the BC and AD, just that of present more attention is been shown towards biometrics and its applications. 2.1 Why Biometrics Applications In the application of biometrics towards security setting is â€Å"Ten times† the security for that of traditional means and also cost effective in the long run. Due to issues relating to Identity theft, terrorism and increase in the general level of crime which have also combined to heighten the need for a just technology security approach.( Security Seminar K. Tracy 1998) Biometrics application over the years has been the recommended solution choice for many organisational systems towards information security, both privately owned and government companies are in use of biometric application towards maintaining secured environmental system for information sharing and distribution. Lets imagine the ability to unlock the door, obtain money from a machine, authenticate a credit card, retrieve information from a system or even start a car with just a glance at a camera or a touch, that is what bio application is all about and has helped to improve users security application by there uniqueness. 2.2 Introduction to Biometrics What Is Biometrics: The word biometrics is known to be gotten from a combination two words from Greek origin meaning (bios =life, metrikos (metrics) =measure).The terms Biometricshave been in existence since the 20th century and was used to refer to the field of development of statistical and mathematical methods applicable to data analysis problems in the biological sciences (Nanavati. S. 2002). In the nutshell biometrics can be said to be an automated method in science and technology which is used in recognising, measuring and statistically analyzing biological data of an individual. These bio measurements are done based on ones physiological or behavioural characteristics, which can be used to verify the identity of the individual. Some of the examples of biological characteristic include DNA, blood group genes, whereby physical characteristics include fingerprints, eye retinas and irises, facial patterns and hand measurements, and behavioural characteristics include signature, v oice, gait and typing patterns (keystroke). One of the greatest important advantages of biometrics lies in the fact that physical or behavioural traits cannot be transferred to other individuals, or can they be forgotten. (Wikimedia Foundation, Inc, (2006),) 2.3 How does biometrics work? Biometrics can be classified in two main types, which are as follows: â€Å"physiological biometrics†, this involves the use of physical trait, such as a fingerprint, iris, hand or face for recognition of an individual. Here the physical traits are collected, then analyzed, measured and stored for use. In the case of fingerprint, it is automated through a numeric encryption of its ridges, splits, dots, valleys, furrows and minutiae points. This encryption is called an algorithm, creating a binary encoded template. The iris is also digitally stored using an algorithm in the same way. (Wikimedia Foundation, Inc, (2006)) The other type of biometric solution is â€Å"behavioural biometric†. This mainly involves the use of a persons behavioural trait or pattern, such as a voice, signature or key stroke. These traits are stored in the same way to that of the physiological traits except that they are updated regularly to be able to cope with the ever changing patterns in the trait. The both type of biometrics are relevant to different situations and circumstances. Naturally it has been gathered that physiological biometrics has proved to be more reliable than that of behavioural biometric, in the sense that physical traits generally stay the same all time irrespective of the age, while that of behavioural trait changes due to one or two situation which can be caused by advancement in age, learnt habit or accidental causes. 2.3.1 Mode of biometric operations: Identification: In biometrics operations, when the device/networked server hold a database of registered users and when these traits are presented, it is then authorizes the searching of the database so as to establish a match with the presented trait. In theory the device is asking â€Å"Do I know you?† This method of identification is called one too many (1: N) according to â€Å"www.posid.co.uk†. Authentication: The theory here is that the device is requesting â€Å"Are you who you claim to be†? By presenting a user id number or a Smartcard (containing the biometric algorithm) you then prove who you claim to be. In order to prove that this id number or Smartcard belongs to the user, one is requested to present his /her biometric trait directly to the device. You are authorized if they match and denied if they do not match. This method is called one to one (1:1) â€Å"www.posid.co.uk†. Authorization: In the nutshell this is known to be the last stage of a biometric system function, after identification the system search for a match and then confirms it authentication where by requesting unique feature and if matched with the stored details, you are then authorized. (Wikimedia Foundation, Inc, (2006)) 2.4 Importance Of Biometrics Over Traditional Authentication Methods:- In present times most organisation, make use of Login passwords, PINs, and token towards verification and authentication for gaining access to there information database system. This are mainly designed to help protect and secure the organisations computer information network and its applications. However in most cases these technologies have been discovered to having some problems associated with them, mostly when faced with modern technology applications, like online transactions, which could involve the accessing of sensitive information such as medical reports, financial or income support information. In order to reduce these increasing problems, biometrics features are been introduced in some of these computer information applications areas. As earlier stated, â€Å"Biometrics† is known to be an automated methods of recognizing and identifying an individual based on their physical or behavioural characteristics.†(Samir Nanavati, Michael Thieme, Raj Nanavati 2002) Ev ery individual different biometric characteristic which are unique and peculiar to them, no two person have or share the same biometric features. Some of the commonly known used biometric applications in todays society are facial, fingerprint, iris, hand scan, voice and dynamic signature. Biometric data application as a means and methods of identification is well preferred by organisation due to its several advantages over the known traditional method, which have been highlighted earlier in this chapter. Some of the major reason for the preference of bio data for information security system is that the individual to be identified is required to be present physically during the identification process, and this identification process does not require the need for password remembrance in any form. With the present increasing integration of computer, as well as internet usage in our day to day activities towards information accessing, this has called for a growing need to use a more pro tective method on information system assessing. This could be done by either replacing the PINs (traditional method) totally with biometrics or combining the both towards effective security measures whereby prevents unauthorized access to computer information system. As stated in previous chapter, one of the biggest issues with the use of PINs or passwords as a security measure is that it could be forgotten, likewise tokens such as passports and drivers licenses may be forged, stolen, or lost which is unlikely in biometric traits. Basically biometric applications can be used for real-time recognition, and the most popularly used is face, voice, signature, iris and fingerprint. (S.Nanavati, M. Thieme, R. Nanavati 2002) In view to biometric application compared to the traditional application, a biometric system is basically known to be a pattern of recognition of an individual by determining the authenticity of a specific physiological or behavioural characteristic possessed by the pe rson. Several important issues are put into place during designing a functional biometric system. Basically all biometric systems consist of three (3) basic elements, which are as follows: Enrolment: It is known to be the process which involves the collecting of biometric samples from an individual, and this is captured and stores in a secured template in a central database or a smart card issued to the user. Templates: This is a storage cart where all the data or information representing the individual/enrolees biometric features is stored. The template is usually been retrieved when identification is to be carried out on an individual.Biometrics system can operate using either verification (authentication) or identification mode. Matching: It is a process which involves the comparing and analysing of individual biometric details which has been stored in the database system templates. Mainly the enrolment is the first stage during authentication, in which a template is then generated and will be used towards matching of the users authentication. 2.4 Types of Biometric Technologies Biometric can be classified into two main classes which are Physiological and Behavioural biometrics, this involves two main modes of applications, which can be said to be contact and contactless biometric applications. The main function of biometric technology system is to assist in the controlling of access to a network system, and also helping to authenticate an individual by establishing there identity by comparing it with already stored details, which are unique to the individual. The most significant factor which enable the implementation of a biometric towards authentication is it uniqueness, i.e no two person can have same bio data and can not be lost or guessed. Looking at the recent increase in the breach of information system, biometric authentication system is a more reliable, efficient and effective to reduce this increasing threat compared to the traditional password based authentication process. 2.4.1 Physiological Biometrics:- In this type of biometric application, the individual is required to have biometric features stored in the bio data storage device (scanner).This device is where the users details are collected and stored for feature use. Due to reason that a person or individual stores their bio-data and need to make direct contact when needed to gain access to an information system, has made many people have to consider this to be a technology which invades on ones personal privacy .Below are some examples. Fingerprint Evaluation: This is the most commonly used biometrics and the most advanced of all the biometric technologies and it is highly accurate. The challenges lies in varying quality of fingerprints across individuals and in dealing with wear in the defining irregularities in the ridges and valleys of ones finger (Nanavati. S, (2002),). New technologies have recently employed the use of pattern matching and ultrasonic scanning rather than evaluation of the irregularities which has increased the accuracy of fingerprint scanning and reduced the risk of misidentification. By scanning the geometry of an individualshand, including height, width, shape and proportion, security systems can accurately recognize and identify individuals. This method is primarily used for physical access control and is considered the most useful in terms of durability and application. In fact, hand scanning is used effectively where other biometrics technologies cannot work due to frequency, volume, or environmental disruptions. Here is a finger print sample from Wikipedia. Retina Scanning: is considered among the most accurate of the biometric technologies through its evaluation of the shape and make-up of inner surface of the back of the eye. This method, while highly accurate, is also fairly costly and often perceived as difficult to use. Other complications include interference from foreign objects such as eye glasses or contact lenses. Further, scanning of a sensitive area such as ones eye decreases receptivity and willingness to use. Even so, the accuracy of retina scanning and the minimized risk of imitation make it useful in extremely high security areas where accountability is of utmost importance (Nanavati. S, (2002),) . Hand/Finger Geometry Hand or finger geometry is an automated measurement of many dimensions of the hand and fingers. Neither of these methods takes actual prints of the palm or fingers. Only the spatial geometry is examined as the user puts his hand on the sensors surface and uses guiding poles between the fingers to properly place the hand and initiates the reading. Hand geometry templates are typically 9 bytes, and finger geometry templates are 20 to 25 bytes. Finger geometry usually measures two or three fingers. Hand geometry is a well-developed technology that has been thoroughly field-tested and is easily accepted by users. (Nanavati. S, (2002),) See example below of a typical hand geometry. Iris scanning: This is similar to retina scanning in method and level of accuracy. However, its application is considered less intrusive and is thus becoming more common. Recently, it has been introduced into the airline and banking industries and while system integration remains a challenging part of implementation, improvements are continually being made (5). Facial Scanning: These applications are most often used in conjunction with other verification methods such as identification cards systems or with existing security cameras and monitors. This method utilizes high resolution images of distinct facial features such as eye sockets, shape of the nose, and/or the position of certain features relative to each other (1). Problems arise with this application if the subject is not properly positioned for the camera or if environmental changes such as lighting changes prevent an accurate read. (Nanavati. S, (2002)). 2.4.2 Behavioural Biometrics: Behavioural biometrics is said to be the ability for a system to be able to recognizing, identifying and authenticating a users based on there behavioural characteristic, which are unique to them. Basically this type of biometric can be learnt or developed over a period of time, and may follow a particular pattern of usage by the individual. Example of some behavioural traits used in biometrics is as follows: handwriting, speech, keystroke, walking pattern, e.t.c. In the nutshell, this type of biometric identification over a certain period can be changed due to some factors like age, weather etc. As a result of the changes in this type of biometric application, for the system to still maintain a secured system training or registering repetitions is to be carried out from time to time. Some of the behavioural biometrics are stated here below and will be explained further as we proceed in this research work.( Nanavati. S, (2002)) Signature Verification: This verification means has been existing for a long time, they are mostly used in the banking sectors to identify individual who make use of there services. They are used mostly to give authorisations to documents like cheques, contracts and sensitive documents. Despite its long time existence, automating the recognition process remains a challenge because peoples signatures are not always identical and can change drastically over time. These changes could be as a result of some factors like old age, mental or physical state e.t.c Voice Recognition: Is a behavioural biometrics which is mainly based on an individuals speech pattern. Here a persons voice is compared or recognized based on its previously recorded stored voice output. Voice verification is a sensitive biometric type of approach because of its acceptability by a lot of user and also high rated error could be significant since it is not really invasive like the physiological biometrics, an example of its use is in â€Å"telephone transactions†. (Nanavati. S, (2002)) Keystroke Biometrics: This type of behavioural biometrics is an automated method of examining and monitoring the typing patterns of an individual on a keyboard. The technology examines and determines the dynamics characteristic rhythms, speed, and pressure, also calculating the total time used in typing a particular word, the time the individual or user takes to hitting certain keys. This technique could be combined with the traditional password system to improve security when accessing sensitive information on computer systems using keyboards or mouse .Basically this method of verification is quite new and still in it development stage, but not to say it has not been in use. Also the â€Å"keystroke biometrics is of high flexibility† because it can accommodate the changing of password over a time when users observes behavioural changes. The keystroke biometrics as it has advantages so does it have its disadvantages as well. In the nutshell these said biometrics applications (Keystroke biometrics) will be talked about more as we proceed in the research work. 2.5.0 Advantages and Disadvantages of the Different Identification Mechanisms. The pros and cons associated with specific devices are highlighted below: Fingerprint Readers Pros  · Not much storage space is required for the biometric template Cons  · Has traditionally been associated with criminal activities and thus users could be reluctant to adopt this form of biometric a

Essay --

Homeostasis in Zostera marina (Eelgrass) Homeostasis, what is it? Homeostasis is the balance between systems to keep living organisms alive and healthy. For an organism to maintain homeostasis its body systems must react and respond to changes in both its internal and external environments. Majority of body systems in organisms, like a respiratory or circulatory system in animals, are part of their internal environment. One body system that is very important for maintaining homeostasis and is common among many organisms is a respiratory system. The respiratory system is responsible for disposing of carbon dioxide and in taking oxygen (vice versa for plants). Some parts that make up a respiratory system are the lungs, windpipe, and cilia in animals. Another body system important to homeostasis and common among animals is a circulatory system, used for bringing nutrients like glucose and oxygen to body cells. Some parts that make up a circulatory system are a heart, blood, and tubes for the blood to travel through (veins, art eries, and capillaries) in animals. There are many more body systems important to homeostasis, but if one is disrupted it’s vital for it to be restored to normal. It is very important for organisms to maintain homeostasis because when it’s disrupted that could cause other systems to go out of balance, which may result in damage in the organism. Homeostasis can be disrupted in many ways like when a human is sick. When a human is sick it starts in the immune system and depending on the intensity of the sickness it can cause other things like water balance and body temperature to go awry which would affect other systems. Another scenario when homeostasis is disrupted is when a plants water level is low and it wilts... ...hroughout the Eelgrass. Excess water in the form of vapor is disposed of through stomata on the leaves. The gas exchange, root, and shoot systems are used in this exchange because the stomata release the excess water in the form of water vapor, which was first absorbed by the roots in the root system, then transported through the xylem in the shoot system throughout the eelgrass. Another exchange that goes on in Eelgrass is nutrients to plant cells. Again the gas exchange, root, and shoot systems are used. Nutrients are absorbed by the roots and made through photosynthesis; stomata take in carbon dioxide which is used along with light, water, and other nutrients previously stored to make more. Nutrients are carried throughout the plant to plant cells by the phloem. Homeostasis is the balance of systems in organisms and it’s very important to keep them in balance.

Evaluate the extent to which Freud’s theory of psychosexual development can help us to understand a client’s presenting issue? | Psychosexual Development Theory The meaning of the psychosexual theory has nothing to do with sexuality or sex in terms of reproduction, but is referred to in meaning as anything that gives pleasure to the body such as a hug, taste, food, this is according to Freud. Freud believed that early childhood has an effect on the future life of person there are five stages he believed that a person went through physiologically and psychologically.The physiology is based on human instinct to survive, the psychology is the emotional/mental interpretation of the act and the pleasure that it provides. This was the birth of psychodynamics the link between physiology and psychology, the motivation behind the behavioural action. Freud’s psychosexual theory is based on child development from birth through to adult hood. The idea is the association betw een the physiological developments being linked to the psychological development in early childhood.The first stage is set at birth to 18 months, it is the oral stage, this area is based on the mouth and the need to eat to survive also coupled with the pleasure that follows through with taste, this is instigated by breasting feeding. Babies enjoy breasting feeding it is soothing, it feels good and it tastes good, this is the first pleasure that babies have. This stage focuses on the mouth as babies learn through taste; they put things in their mouths to learn. It is at this stage that a child learns that the mouth gives instant pleasure through taste and that food gives pleasure.Following the oral stage is the anal stage which is based on the anus; this stage normally occurs around 18 months to three years old. This stage is based on control, this is the control of the bowels being able to control when and where to excrete. The pleasure principle here is based around potty training, the emphasis placed on the child to control when they need to release themselves and the parent displaying expectation on the suitability and necessity of having control over the bowels and taking ownership of actions based around potty training.Depending on how this is executed the developing child will learn the control factor and get pleasure for being able to exercise their control over this. Stage three is the phallic stage this is from ages 3-5, at this stage the child starts to realise that there is a difference between boys and girls; it is here that the developing child sees a difference in their genitals relating to the parent from the opposite sex. Females start to become aware that they don’t have a penis and sense there is a difference in terms of strength between men and women.Males start to become aware that they are strong and have a sense of protection regarding their mother. This can be understood in terms that girls seek protection from their fathers and s ee their mother as a rival and this follows in reverse regarding sons and mothers. Stage four from ages 5 to adolescence is latency it is the lull stage where nothing further happens in terms of development in the psychosexual theory. Stage five genital stage this is the adult sexual phase, this is where the developing person experiences sex, romance, love, crushes and friendships.The relationship of the five stages manifested through to adulthood is as follows. During the oral stage should there be a disruption such as feeding was unsuccessful or issues to do with health pertaining to the oral area then it would manifest through the individuals behaviour resulting in direct issues regarding the mouth. The conflict here is weaning the child off the breast towards solid foods, if this process is handled in a less satisfying way towards the developing child, the outcome can be an anxiety lead habitual acts.This could result in chewing pencils, thumb sucking, gum chewing, smoking, over eating, not necessarily in an order but the idea is if an individual becomes fixated in the oral stage they may have some anxiety that would be displayed in one of the above actions. This stems from the idea that the individual was not breast feed enough or there was a disruption of some kind relating to feeding or weaning was unsuccessful and caused issues with feeding, due to this need not being met as an infant the need manifests itself in some other behavioural type.The anal stage relates to control and is the stage where the concept of potty training was either successful or not, resulting in the individual being either â€Å"anal retentive† meaning up tight and rigid when it comes to neatness and organisation. This is the idea that the individual enjoyed their potty training. On the other hand depending on how the training was administered. For if the child was not forth coming in their potty training or the training was not handled ppropriately or was very easy going and care free, the idea is that the individual would be disorganised, messy and have possible anxiety with anything to do with passing bowel movements. The phallic stage relates to relationships with the opposite sex through the understanding of the relationship between the individual and the parent of the opposite sex. This is the origins for the Oedipus and Electra complex stage. Boys tend to want to protect their mothers and come into conflict with their fathers as a means to assert themselves. Girls seek the protection of their fathers while they rival with their mothers for his attention.The child suspects that the same sex parent knows about their attraction towards the opposite sex and hates them for it. The latency stage is the stage of pure childish playfulness, there is no pleasure factor here but child growth such as school, play, fun and basic child features. The focus is on interacting and taking in their surroundings. This is based on repression driving from the stage prior to this one, because of the awareness but the lack of knowledge about the differences between male and females, the child tends to repress any thoughts feelings or concerns and so begins the latency stage.The genital stage is the sexuality process and the discovery of pleasure through the genitals, at this stage boys begin to masturbate and for some this can be uncontrollable. It is not uncommon for parents to reprimand a child for being caught too often with their hands down their pants. And the threats of castration are common to try and deter the boy from such impulsive acts. For girls the suspicion is based on their sexual development in terms of their physical being, breasts grow and the female form takes shape.In this way, and for such reason, the child’s feelings on the subject of his relationship with his parents, and their attitude towards his body and its future, may become divided. What Freud Really Said: An Introduction to His Life and Thought: 1965 David St afford-Clark: Hachette Digital: Location 1254 This theory is Freud’s theory and although it has come into must dispute and criticism it is a theory that may not necessarily be utilised to its fullness however not completely disregarded. The ID the Ego and the Superego These stages are portioned and governed by three powers of the mind that Freud believed to be within everyone.The ID described as the self, instinctual and primitive, the Ego understood as the mediator, intelligent and sensible, and the Super Ego acts as the conscience it is institutional and ensures ethical actions. The ID which is known as the pleasure principle the, I want, I need is the driving factor towards getting our needs met, this is the selfish mode which informs us that we are hungry, lonely, sick. This factor has no relevance in the how are these needs to be met, but rather in the fact that these needs are present and need to be fulfilled.The Ego facilitates the needs of the ID ensuring that it is i n line with reality and acceptable to fulfil those needs that the ID manifests, the ID creates the desire and the Ego works out how to get the desires met in balance with society and appropriateness. The Super Ego is the conscience the moral side of the mind, it ensures that the morality is in place throughout the drive from the ID’s desire to the Ego’s will to get the desires met in accordance to appropriateness, the Super Ego balances the morality and acts as a reminder that behaviour should be managed in a moral standing.This is the Freud analogy of the human mind and how it is motivated and managed by the individual. The oral stage is governed by the ID as this is the immediate survival stage such as feeding, then the Ego which develops during the oral stage which leads on to the next stage. By the anal stage the superego has develop hence the control over bowel movements and the potty training by a parent who may install certain values as to why big boys and girls use the toilet. By this stage the personality has now come into form.The main criticism of these theories are that it has never been experimented or deemed true by means of observation, it is all Freud’s ideas and thoughts on how the human psyche works, there is no evidence to prove it right or otherwise. The link between the psychosexual theory and adult neurotic behaviour Freud believed that any sign of neuroses stemmed from childhood, of which would indicate that there was a disruption or conflict during one of the five psychosexual stages.This basically links the idea that there was an issue of some kind during childhood and this issue has caused a lasting unwelcome effect on the future wellbeing of an individual. The disruption would take the form of some kind of conflict, during one or more of the psychosexual stages, which could lead to a behavioural transference neuroses or narcissistic neuroses. Due to Freud’s theory on the ID Ego and Superego the relationshi p between the three mind concepts is crucial to how the disruption or conflict was handled during the development of the psychosexual stages.Due to this concept Freud based his belief on neuroses being related to a particular trauma suffered during childhood. The psychosexual stages are guides to pinpoint the particular issue giving it a shape and a link to assist in understanding certain behaviours and the possible reasons behind them. Applying the Psychosexual theory to the presenting issue The idea is to link the presenting physiological behaviour to childhood growth of where there would have been a possible disruption or conflict.So a client with abandonment issues who has a tendency to over eat to the point where it is damaging to both their physical and mental health. The psychosexual link would lead towards their oral stage, suggesting that from birth to 18 months the transitioning from breast feeding to solid food was unsuccessful or held some form of conflict or disruption. The idea is that because the client has an eating disorder coupled with feelings of abandonment suggests that they are fixated within the oral stage. This would be a basis to first understand the client and their issue from an open point of view.Freud’s psychosexual theories have never been tested so to apply it in full would be irresponsible to say the least. Ethically the use of the psychosexual theory is not always recommended for it holds a lot of emphasis on a sexual related basis. However because it holds a possible understanding for which to build rapport and get to a level of understanding with a client, it should not be totally ruled out. The psychosexual theory can be used to understand a client but to the extent that it offers an understanding towards the presenting issue, however this could not be the case with every client.As Freud’s theories were limited to certain classes and groups of people, the ramifications may be similar in respect to other classes and groups of people but they may differ completely. Due to cultural difference and ethnic origin coupled with tradition and religion from the vast amounts of different people in the world. The childhood growth from one individual to another could be very different, whereas culturally in some areas of the world breastfeeding can last up until a child is 5 years old. How at this point is the psychosexual theory to be employed? How his form of childhood transitioning could be applied in any way to the psychosexual stages? The fact remains that due to its limitations of experimentation; it cannot be applied to everybody but instead used as a tool to better understand a client’s presenting issues. Issues such as OCD, over eating, anorexia, IBS, anxiety, phobias, grief, habits and addictions can all be linked to the past events or experiences of a client’s life. It may not necessarily be linked through the psychosexual theory but the link may very well be in the past holdi ng a strong relevance in some form to a past experience.For this reason alone the psychosexual theory can be used as an avenue to understand the client and the relationship between their presenting issue and their past. Here is where the psychodynamics of the clients frame work are interpreted and understood and possibly confronted and dealt with in order for the client and therapist to progress with some resolution. Criticisms of Freud The main areas of criticisms on the psychosexual theory and many other Freudian theories are that it has not been tested.All of Freud’s theories were based on his ideologies and internal beliefs, so it has no scientific creditability. No prognostic worth as to place the Oedipus and Electra complex on an individual that had an absent parent or was raised with same sex parents or in another less conventional family setting, how is their future behaviour to be determined. Freud based his analysis on the patients he had access to, this was not a w ide variety of individuals and many of them were middleclass wives suffering from hysteria. This is just a few of the many controversial views on Freudian theory.However along with these criticisms Freud claimed much recognition for his contributions to psychology. Before Freud there was no understanding of the mind and how it could possibly work, Freud opened the understanding to undertake that the human mind can operate on different levels. Freud gave birth to the importance of child psychological development and that children do have sexual feelings. Freud set the motion for the direction of psychology and the many areas of which can be explored, without Freud’s theories there was no basis for psychology and its possibilities.Freud gave direction and a starting point for many practitioners to base their understandings. Presenting issues and the psychosexual development theory The psychosexual development theory can prove useful in understanding a client’s presenting issue, but only as a tool to base an understanding. This theory gives a platform to further develop the client and therapist relationship, it holds not scientific value and is far too controversial to rely upon as a workable useable theory for practice. But it does allow for understanding and gives light to uncovering an issue using psychodynamic therapy.

Emotional Eating Essay

Emotional eating is a disorder that involves the intake of food as motivated by an individual’s emotional state instead of biological processes (Canetti, Bachar, & Berry, 2002). Even if an individual is not hungry or already full, eating still continues as response or coping mechanism for certain emotional states, usually negative emotions such as anger, anxiety, confusion, loneliness, or sadness. Emotions related to stress also cause emotional eating. The common view of emotional eating is as a temporary condition triggered by the onset of certain emotions. Commonly, this becomes a problem for people only when this has progressed to other problems such as depression or obesity. Nevertheless, the number of people experiencing emotional eating supported efforts to address the emotional problem in clinical practice. Emotional eating could also lead to serious physiological and psychological health problems if unresolved as well as comprise the possible manifestation of other underlying clinical problems. Addressing emotional eating becomes a preventive measure and solution to more serious problems. Existing interventions include psychiatric counseling and diet monitoring by a nutritionist (Field et al. , 2008). However, the treatment of emotional eating depends on individualized diagnosis (Buchanan, 2004) because of variances in the causes and manifestations of the condition in different people. Emotional eating is a disorder with environmental and psychological components. These two components explain the causes and manifestations of emotional eating and point to intervention or treatment options that should consider these two components. The environmental component of emotional eating refers to two causes of the disorder. One is social eating or the common practice of socialization around food. Social gatherings usually bond around food with people consuming more than usual to celebrate an occasion. It is also common for friends comforting each other and providing support, to eat comfort foods that are usually high in sugar. The other is the childhood habit of food as a means of expressing care or reward resulting to the development of emotionally driven attachment to food in adulthood. The celebration of every success is food, with the quantity reflecting the value of the success to the person. All situations requiring comfort also calls for food intake. (Field et al. , 2008) The psychological component revolves around stress as the trigger for emotional eating. Stress elevates the cortisol levels of individuals. Cortisol is a hormone released by the body to respond to stress through heightened mental functioning or boost of energy. However, excessive release of cortisol could cause people to crave for food. Anxiety and depression could also cause people to eat to calm themselves or to ease their discomfort. (Canetti et al. , 2002) Current and Future Research and Treatment Directions on Emotional Eating The current research on emotional eating focuses on the causes and manifestations of emotional eating to diagnose individuals, the role of personality typologies in aiding diagnosis and identifying risk groups, the consideration of gender as a ways of determining risk groups, and treatment options. One explanation for emotional eating is general dissatisfaction. A study determining the propensity to engage in emotional eating of individuals, by using Maslow’s hierarchy of needs, indicated that people placing themselves at the lower levels of the needs hierarchy have a higher propensity to eat to ease their dissatisfaction. (Timmerman & Acton, 2001) Mood association evolved as another explanation for emotional eating. Depression and negative moods have strong effects on emotional eating. The motivation for emotional eating is to experience the well-known pleasure in eating food, especially comfort foods such as sweets or junk food. Taking of midnight snacks due to the inability to sleep because of anxiety, depression and bad mood supported the association. (Bekker, van de Meerendonk, & Mollerus, 2004; Grilo & Masheb, 2004) Human ecology also emerged as a causal explanation for emotional eating. The positive factors associated to food determine emotional attachment to food in times of anxiety, depression or stress. The media also tempers people’s emotional attachment to food. (Field et al. , 2008) Research on the means of diagnosing emotional eating and other closely related eating disorders focused on personality typologies to help in identifying risk groups. People with personality disorders comprise a significant number of people diagnosed with emotional eating and other eating disorders (Picot & Lilenfeld, 2003). Individuals with low self-esteem are also more susceptible to eating disorders (Beeker et al. , 2004). Impulsiveness and thrill-seeking behaviors are also more likely to develop eating disorders with the fulfillment of cravings made to satisfy the need to experience new sensations (Grilo & Masheb, 2004). Gender, age and race are also focus of studies on risk groups for emotional eating. The study of night eating showed that men are more likely to eat food after dinner (Grilo & Masheb, 2004). Women and minority groups have greater concerns over shape and weight due to media influence and cultural norms leading to the perception of food as tempting pleasures. This leads to the attachment of comfort and pleasure to food. (Patel, Pratt, & Walcott, 2003; Ross & Wade, 2004; Vingerhoets, Nyklicek, & Denollet, 2008) There are two interlinked research trends on interventions for emotional eating. One is prevention through early detection via psychological tests. The questionnaire for eating disorders (Q-EDD) could be a diagnostic measure for emotional eating intended to apply to all eating disorders (Callahan et al. , 2003; Milos et al. , 2005). This is a general diagnostic test for all kinds of eating disorders with psychological components. The emotional eating scale (EES) remains an important specific tool in determining people susceptible to emotional eating as well as identifying the existence of concurrent disorders such as depression or personality disorders. (Palmer, 2005; Courbasson, Rizea, & Weiskopf, 2008) Interviews are important diagnostic tools in determining case history and personality factors (Callahan et al. , 2003; Palmer, 2005). The other research trend is treatment, which could be either inpatient or outpatient depending on the co-occurrence of other disorders. The goal of treatment could be the achievement of healthy weight through behavioral weight management programs, alleviation of physical complications, management of co-occurring psychological disorders through drug administration and/or psychotherapy, and ensuring non-relapse through self-help strategies (Pritts & Susman, 2003). Other interventions include anxiety and stress management, diet, exercise, and an overall healthy lifestyle for people without co-occurring psychological disorders to stop emotional eating. A number of alternative treatments exist to stop emotional eating by targeting stress such as acupuncture, relaxation exercises, and herbal medicine. (Cleary & Crafti, 2007)
