Psychological Impacts of Nostalgia for People With Dementia

Psychological Impacts of Nostalgia for People With DementiaTHE mental IMPACTS OF NOSTALGIA FOR PEOPLE WITH DEMENTIA STUDY PROTOCOL1.0 INTRODUCTION1.1.2 Existential realitiesFour basic concerns that contract been proposed to discombobulate great impact on the lives of all spate argon death, freedom, empiric isolation and momentlessness (Yalom, 1980). Yalom (1980) argues that although flock tend to neglect these four realities, they are still pervasive and influential on our lives. He offers the next explanations to these realities which he refers to as ultimate concerns. He explains that the inevitability of death is a fact of feeling which we are all aware of irrespective of the central human desire of existence. The central experiential difference of opinion is the gallop between the realisation of the inevitability of death and the desire to continue to live. From an existential perspective, freedom refers to the lack of push through-of-door structure. Paradoxical to an individuals everyday experience, human beings do not reside in a universe that has ingrained design and is well-structured. Instead, the individual is totally the orchestrator of his or her give birth choices, knowledge domain, actions and design. Freedom from this view implies superbly that there is no ground beneath us. The key existential dynamic in this sense is the encroach between our encounter with groundlessness and our desire for ground and structure. As humans, our reality of freedom is evidenced from the conflict which arises from our inlet of self-determination and our realisation of lack of support and un certainty. This happens when one recognises the things that happen in ones life are up to oneself.The third ultimate concern is isolation. This form of isolation from an existential sense does push to neither interpersonal isolation (such(prenominal) as loneliness) nor intrapersonal isolation (such as isolation from oneself). This form of isolation refers to fundamental isolation. This means that no matter how close we are to each other, unavoidably, we are on our own. Each of us comes into existence alone and must exit from it alone. Thus, the existential conflict is the strain between our realisation of our unquestioning isolation and our desire for contact, protection and to be part of a larger group (Yalom, 1980).Accumulation of the trine realities results in the fourth, which is, meaninglessness. In a world where there is no absolute truth and the only certainty about life is death, life tends to be meaningless. People will cling unto values and concepts in an endeavour to formulate meaning in life. Life essentially has no meaning if death is inevitable if our own world is constituted by ourselves and if we are fundamentally isolated (Yalom, 1980). As Yalom (1980) elaborated, the existential dynamic conflict emerges from the impasse of a meaning-seeking creature that is put into a universe that possesses no meaning. It merchant man be argued that although these existential realities are experienced by all human beings in one form or the other, close to categories of persons are more likely to experience profound aspects of these existential threats. One of such groups of quite a little is good deal with delirium.1.1.3 Dementia an existential threatDementia is an existential plight of persons and not simply a line of work to be investigated and managed through technical skill (Baldwin and Capstick, 2007 p. 117). It has been regarded as a disease of the entire person or else than a mere illness of the brain (Murray and Boyd, 2009, Passmore, Ho and Gallagher, 2012, Post, 2013, Nowell, Thornton and Simpson, 2013). With its associated health and social problems and deterioration leading to death, aberration can be perceived as a form of existential threat (Cheston, 2011). People with delirium experience changes in biographical factors. These biographical factors are the changes in later life. Whereas s ome throng with dementia go through their illness with most of the mechanisms that previously supported them still unblemished, others go through a sequence of shineing and disheartening changes in life with massive surrender in their personal resources. much(prenominal) personal resources refer to that which has been inherently developed by the person including all the consequences of social learning. These include aspects such as ways of managing crisis, breathing out and modifications willingness to accept help offered by others and defense against tension or anguish (Kitwood, 1993). Social psychological factors that make up the fabric of everyday life could enhance or diminish the sense of value, safety and personal being of the person with dementia. These have been enumerated and framed under the purview of a malignant social psychology (Kitwood, 1990 p. 180). These include treachery, disempowerment, infantilisation, condemnation, intimidation, stigmatisation, outpacing, i nvalidation, banishment and objectification (Kitwood, 1990, Kitwood, 1993).Dementia as an existential threat denies a smooth adjustment into the existing self-concept of the person affected by dementia (Cheston, 2013). Cheston (2011) also argues that the threatened loss of cognitive ability for volume with dementia could influence the way in which they make sense of the world and their self-esteem. He further expounds that existential realities are more prominent for concourse affected by dementia and can be evidenced in the subjective experiences of people with dementia. People with dementia seek for adherence (Piiparinen and Whitlatch, 2011, Van Assche et al, 2013, Osborne, Stokes and Simpson, 2010, Browne and Shlosberg, 2006, Perren et al, 2007, Stephens, Cheston and Gleeson, 2013), meaning/ purpose in life (MacKinlay and Trevitt, 2010, McGovern, 2011, McGovern, 2012, Phinney, 2011) and experience loss of personal identity (Eustache et al, 2013, Steeman et al, 2013, Caddell a nd Clare, 2012, Caddell and Clare, 2011). These could be perceived as coping mechanisms to buffer them against their encounter with existential realities.It is suggested that existential threats could have adverse effect on an individuals self- esteem (Sabat, 2002) affect (Xu and Brucks, 2011, Van and Van, 2007) social connectedness (Mikulincer, Florian and Hirschberger, 2003) meaning in life (Sullivan, Landau and Kay, 2012, Jaarsma et al, 2007) and popular wellbeing (Piiparinen and Whitlatch, 2011). Likewise, it can be argued that dementia as an existential threat has comparable potential effects on people with such a condition (Baldwin and Capstick, 2007). In addition, various studies have suggested that the early stages of dementia, after receiving a diagnosis, generally cause profound psychological effects on self-esteem, meaning/ purpose in life and general psychological wellbeing (Chistopolskaya and Enikolopov, 2013, Bamford et al, 2004, Steeman et al, 2006, Husband, 1999, Husband, 2000, Vernooij-Dassen et al, 2006).1.2 Problem statementDementia as an existential threat has associated adverse psychological impacts for people with dementia. These include but are not circumscribed to threats to identity Steeman et al, 2006), social connectedness (Hatch, 2013), meaning/ purpose in life (Lingler et al, 2006, Macquarrie, 2005) and general psychological wellbeing (Piiparinen and Whitlatch, 2011). Consequently, people with dementia sometimes use the yield of the past as a mechanism in an attempt to buffer the psychological effects of dementia (Bohlmeijer, Smit and Cuijpers, 2003, Woods et al, 2005). Also, conventional approaches such as recall and life review activities employ the use of the past as a resource for the present to offer various psychological functions for people with dementia. However, the efficacies of these activities are still debated (Douglas, James and Ballard, 2004). For example, whereas some randomised controlled trials and systemat ic reviews bring to an end that these approaches may improve the psychological wellbeing of people with dementia (Lai, Chi and Kayser-Jones, 2004, Wang, 2007, Sharif et al, 2010, Wu, 2011, Azcurra, 2012, Korte et al, 2012), others have concluded other than (Wang, Hsu and Cheng, 2005, Wang, Yen and OuYang, 2009, Gudex et al, 2010, Forsman, Schierenbeck and Wahlbeck, 2011, Woods et al, 2005, Woods et al, 2012). Stemming from memory decline in dementia, the merging of past experiences with the present can arguably enhance self-concept and self-esteem if the images of the past stimulate a sense of pleasure and accomplishment (Kasl-Godley and Gatz, 2000). Perhaps, the recall of the past without deliberately evoking nostalgia is not an ideal way to effectively enhance and improve the psychological calm of people with dementia.On the other hand, nostalgia has been proposed as a psychological buffer against existential threats (Juhl et al, 2010, Routledge et al, 2008). Juhl et al (2010) constitute that in mortality salience conditions, participants at low levels of nostalgia proneness show less positive responses to an identity threat, greater levels of death anxiety and lesser feelings of state nostalgia (self-esteem, social connectedness, meaning in life and affect). Routledge et al (2008) support the idea that nostalgia provides an existential function by providing a source of meaningful life experiences which people use to defend themselves against concerns about death (existential threat). Also, experimental studies with undergraduate student populations have demonstrated that induce nostalgia increases self-esteem, positive affect, social connectedness and meaning in life when compared to normal autobiographical memories (Wildschut et al, 2006, Routledge et al, 2011). However, the use of nostalgia by people with dementia to provide similar desirable psychological functions is not clear (Moos and Bjorn, 2006). Nonetheless, this has not been tested among people with dementia.1.6 Significance of the researchThe current research seeks to investigate whether induced nostalgia increases self-esteem, meaning/ purpose in life and social connectedness for people with dementia as it does for the general population. It also attempts to find out whether people with mild to moderate dementia differ in experiencing various psychological outcomes as a result of their degree of nostalgia proneness. This novel application of the emotion of nostalgia (currently a major area of psychological research) to people with dementia has both clinical and theoretical significance. Theoretically, with nostalgia being suggested to have positive psychological impact among the general population, we will be able to find out whether these functions extend to people with dementia. Clinically, while reminiscence therapy is frequently used with people with dementia research findings are unclear as to whether this has any benefit. It may be that one of the factors determi ning whether reminiscence is of benefit is whether or not a nostalgic memory is evoked. By investigating this, the research may be able to shed light on the way in which nostalgia buffers the psychological challenges of living with dementia. For instance, we may be able to identify more precisely how to help people with dementia maintain a psychological equilibrium, and thereby improve their quality of life and psychological wellbeing.2.0 previous LITERATURE REVIEW2.1 Dementia and meaning/ purpose in lifeExistential psychology attempts to explain the way individuals formulate meaning in the event of an inevitable despair or threat. According to existential psychology, individuals employ various mechanisms to buffer them against existential threats in order to restore psychological balance (Greenberg, Koole and Pyszczynski, 2013). spirit in life is an aspect of wellbeing that is well appreciated by people with dementia (Dres et al, 2006). Research shows that, even in the event of e xperiencing decline in cognition in a tolerant with dementia, the person with dementia still engages in meaning-making that covey important communication messages regarding the importance of life (Robertson, 2013). Also, people affected by dementia are usually in the quest of seeking for meaning in their lives in order to concur with their diagnosis (Lingler et al, 2006, Macquarrie, 2005). Searching for meaning in life by people with dementia is linked to the expression of establishing identity (Steeman et al, 2006).Dementia is associated with various levels of cognitive decline (Franciotti et al, 2013). Cognitive decline has been found to be associated with decline in aspects of wellbeing, specifically, purpose in life (Wilson et al, 2013). Alternatively, in advanced age, higher(prenominal) purpose in life causes a reduction in the effect of pathologic changes on cognitive decline for people with Alzheimers disease (Boyle et al, 2012). Longitudinal studies have also provided some evidence in support of some existential functions of having a greater purpose in life. Among older adults living in the community, greater purpose in life has been found to have significant associations with a reduction in risk of disability (Boyle, Buchman and Bennett, 2010), mortality (Boyle et al, 2009), Alzheimers disease and mild cognitive impairment (Geda, 2010, Boyle et al, 2010).

An analysis of age gap relationships

An abridgment of bestride gap consanguinitysViews towards years-gap relationships should non be viewed through stereotypical eyes or else they should be viewed with an free-spoken mind, for they argon more than(prenominal) than what you guarantee.Age-gap relationships experience been around since the dawn of hu humans life. Historically age-gap relationships nonplus been among an senior male and younger female, and many a(prenominal) cultures arranged marriages with this pattern. Age-gap relationships are not socially constructed, simply deplete evolved. They are also seen often in nature. Stereotypes and negative opinions are heard often in media, by booster rockets and by family. Many famous celebrities, royalty, and rock stars have been in age-gap relationships.In many cultures, arranged marriages have been between a young little girl and an erstwhile(a) man, this could have been to prevent marriage outside of the culture, to increase governmental power, for l ivestock, or to resolve inter political issues. Doing this helped to increase the number of the community members, because a young girl could produce many more children than an elder woman. Older men had more resources to support the girl and her take than a young boy. By arranging the marriages in this way the parents were insuring a greater number of live grandchildren to pass on their genes, wealth, legacy and land.At an evolutionary stand point age-gap relationships should be more frequent as well as less criticized. .. men are predisposed to produce as many offspring as possible, to increase the probability that their genes leave be passes onwomen prefer a join who has adequate resources, or the potential to obtain resources,.(Banks and Arnold 2001) By learning to seek these qualities we have subconsciously assure the survival of the human race. This evolutionary process is not much diverse from the way animals use to bring their mates. Mate preferences may have evolv ed, rather than beingness socially constructed (Banks and Arnold 2001), therefore age-gaps should be considered the social norm, and identical age relationships should be considered abnormal.Age-gap relationships have a rollercoaster history, where they were once accept, then they werent, and now they are turn accepted once again. Women senior relationships however are still considered taboo, but that doesnt mean they should be discriminated more. Age-gap relationships whether female sr. or male older should be looked at as a regular relationship. The same challenges and problems should be considered when the relationship itself is being evaluated. Criticism of age gap relationships is similar in the way which different races and hardy couples are criticized, nation look at what is on the outside and not at what they really are. there is an old adage Dont judge a book by its cover and I feel that more people should follow this, not only when dealing with age-gap relationshi ps but when dealing with all situations in which it is not as it appears.There are many different stereotypes put towards age-gap relationships. Such as The younger mate is either looking for a parental figure or is in it solely for monetary gain, and the older henchman is only after youth and physical attributes (Anisman-Reiner 2008). Sadly these stereotypes are neat in more or less situations, but it does not mean that every age-gap relationship is like that. The relationship in question should be examined first, then the age of the partners. Many relationships that were healthy and actually had love in them, were broken up collectible to constant harassment from family, friends, and even strangers.Criticism that age-gap relationships receive are based on extreme instances. The older partner will farm dirty looks and be called a cradle robber or be accused of cheating on their spouse (which other than the younger partner doesnt exist). Other things people say are what could you possibly have to talk about, can they even keep up with you physically or they are holding you back from experiencing your youth this usually causes stress for the couple. These are not always square but it causes the couple to focus on what people say about them, instead of other things in their relationship. Its possible for couples with large age gaps to be able to have common interests, as well as have the same amount of physical activity. For example a 45 year old man can play a game of tennis at the same level as a woman in her 20s, or both could be into classic rock or horror movies. It is true that sometimes when you enter an age-gap relationship you are risking losing some life experiences, but you can create cutting ones that neither of you have had. That way the older partner is not repeating life experiences, and they younger partner is gaining life experiences. Either way age-gap couples get around these obstacles and have healthy lasting relationships.Many peopl e will admit that they have been in an age-gap relationship or they get by someone has. These relationships are becoming increasingly common nowadays and yet they still receive criticism. Although men and women report a preference for and openness to age gaps in their own relationships, they typically disapprove of age gaps in others relationships. (Lehmiller and Agnew 2008) Why would you be willing to consider something for yourself, but then tell your friend that they shouldnt do it? If it is because you know you could handle it and your friend couldnt, what makes you depend you know your friends capabilities better than they do? Better yet if your friend doesnt know herself, then what makes you think you know your own self? These are questions you should ask yourself before you make the decision to discriminate against others being in age-gap relationships. My grandmother and her husband were 25 years apart and yet they did not receive criticism, but when I entered into a relat ionship with a 14 year age difference she made a big deal about it. Sadly this occurs often to people by their family and friends.We are all natural with an incest avoidance instinct, sometimes depending on your upbringing it could go away, but normally we tend to react to what we see before we have a chance to think about it. A difference in age of 15 years and greater would mean that a couple could, in terms of age be parent and child and so we suggest that social opposition to these age-differences will be greater, because people would propensity to avoid the suggestion of incest (Banks and Arnold 2001). Due to the appearance of the couple we instantly think that the older partner could be the younger partners parent. Because of this instinct we become so focused on the difference in age that we dont honour anything else about the relationship.Parents are often worried that when and if their young password or daughter enters into a age-gap relationship, that the older partner will exploit them for sex and not truly love them, or that the partner is close together(predicate) in age to themselves than their child. I feel that though the parents mean well, they should evaluate the relationship and get to know the older partner before being so quick to judge, and fetch out if it is healthy for their son or daughter. Let he who is without sin cast the first stone (John 87).Due to the different rates at which boys and girls mature, age-gap relationships could even be considered ideal to insure the survival of a relationship. Its possible for cardinal people at different ages even with a 20 or 30 year age gap to be equally mature, however you define the term.(Anisman-Reiner 2008) Everyone growing up has heard that girls mature quicker than boys, and it makes sense that this would make it easier for age-gap relationships to work and last. It also answers why many similar-age relationships (especially high school relationships) dont last. As you get older t he age-gap in the relationship matters less, because both partners are maturing.Many famous couples both present and passim history were involved in age-gap relationships. The gaps range from less to one year to more than thirty years. wand Joel and Katie Lee had thirty-two years between them, and Tom Cruise and Katie Holmes have sixteen years between them. These are people we idolize, we watch on television, on movies, and whose music we listen to. One day the media will pick them for cutest couple and then the next day they criticize them, and we only when go along with it, instead of using our own minds. The criticism increases more if the woman is the older partner, and they have been labeled by the media as cougars. Such as Demi Moore and Ashton Kutcher (15 years difference), they receive tons of criticism and yet remain happily married, so far for 5 years. It is not only in present times that age-gap relationships exist, they have been around for centuries. Cleopatra and Ju lius Caesar had more than 30 years between them when their romance began. Another couple would be Frank E. Butler and Annie Oakley who had 22 years between them.During my personal experience in an age-gap relationship I have been lucky to have friends and family to support me, well most of my family. We do get dirty looks in public even though my boyfriend doesnt look that much older than me and definitely doesnt act older than me. If we just focused on what other people thought of us, we wouldnt last. Together we have accomplished so much, and continue to climb mountains I guarantee that if we did not receive the support we have, we would not have made it. You should not discourage an age-gap relationship unless you know for an absolute fact that it would be damaging to one or both parties, you may find that age-gap relationships are a wonderful positive experience.In conclusion age-gap relationships are criticized, stereotyped, and put down. Even though they are becoming more comm on, have been around for centuries, occur in nature, and have proven to have lower divorce rates. Society should look at the relationship, not the ages of the people, and maybe more of these relationships would succeed. Age-gap relationships are just like normal relationships and should, according to evolution, be the social norm though due to social influences this is not the case. Nobody likes to be picked-on especially for something that makes them happy, so we should follow the golden rule Do onto others as you would have them do unto you.Age-gap relationships should be looked at for what they are, not what they seem.

Green Technology: Impact and Uses

Green engineering tinct and UsesAs valet lives argon advancing constantly, the basic inescapably of human being are increase tremendously as well. The human intrusion needs have altered the natural environment and arouses problems such(prenominal) as pollution, climate change and global warming. In order to get rid of these problems, Green Technology is introduces to recover the Earth back to a healthy state. Green Technology is a new applied science that introduced to protect the Earth against environmental pollution. (Renewable Solar Energy, n.d.) It plays an important role in conserving the natural resources and environment. (Whitney, n.d.) Green applied science is known environmental engineering science or clean technology as well. It produced energy to non-toxic cleaning products by using different methods and materials. (Green Technology, n.d.) Green Technology is introduced to reach five goals which are sustainability by satisfying the societys needs without damaging o r depleting the availability of the resources for the future generations, cradle to cradle design by designing products that are reusable, source reduction by changing the amount of raw materials consumption and ways of production to swerve the waste products, innovation by developing new and substitute(a) technologies and viability by creating economic activity such as new simple machineeer that associated with technologies and products. (Green Technology, n.d.) Currently, green technology is developing in 5 majors areas which are energy, green building, environmentally preferred purchasing, green chemistry and green na nonechnology. (Green Technology, n.d.)Green Technology has a salient impact on the international market. According to the BBC research, the international market of green technologies ordain grow slightly 9.2 per cent which is from $200 billion in 2010 up to $311.7 billion by the socio-economic class of 2015. (Companies common sense Market, 2011) alike that, the global market for installation and retrofitting of combined heat and power was $55 billion in the year 2009. In 2010, it has grown to the highest degree 9.1 per cent which is equivalent to $60 billion. Therefore, the BBC estimated that the compound annual growth step (CAGR) will be maintained most 8.4 per cent until 2015 with a total amount of $90 billion. (Companies Sand Market, 2011) Moreover, the BBC research also predicts that the compound annual growth sum up (CAGR) of the global market for waste-to-energy installation and retrofitting will be around 6 per cent from the year 2010 to 2015. This means, it will grow from $22.3 billion in 2010 to $30 billion in 2015. (Companies Sand Market, 2011)On the other hand, the Senior Adviser of environmental Technology and work (ITC), Nikolai Semine stated that, from the year 1988 to 2008, green technologies have provided a global market the roughly worth most $650 billion. (Semine, 2010) It was the same amount as the aerospace a nd pharmaceutical revenues of the leader countries such as United States, the European Union and Japan. Moreover, the European Forum on Eco-Innovation predicts that the global market will increase another $1,650 billion by 2020. (Semine, 2010) According to Nikolai Semine, the developments of South-South trade in green technology has brought up the opportunities on the exportation of green technology and increase its revenues, sustainable development and creates green jobs. (Semine, 2010) There are some(prenominal) countries that are successful in the exportation of green technology, such Malaysia, China, India, Pakistan, Philippines and Thailand. Lets take Thailand as an example. In 2007, Thailand has exported pollution control, water treatment and renewable technologies that generated revenues about US$ 2.3 billion. (Semine, 2010) Green technology also contributes in the expanding of environmental businesses. For examples, the United Kingdoms Joint Environmental Markets Units pre dicts that the environmental business will expand about 10 per cent which is equivalent to US$ 178 billion. (Semine, 2010)On the other hand, green technology also brings benefits to the environment. It attentions to protect the sustainability of natural resources and the environment by removing the threat to the environment. Lets step at one example of the green technology. There are at least 600 million of cars around the world. In addition, the huge amount of cars burn about 120 billion gallons of gas annually and 19 pounds of carbon dioxide is released to the atmosphere by each gallon of gas. (Taheshea, n.d.) According to the United States Transportation Specialists, vehicles that are not energy sufficient have contributed about 45 per cent of the carbon emissions of the world. (Taheshea, n.d.) To overcome these problems, several machine manufacturers such as Toyota, Honda and Peugeot started to execute green technology by manufacturing hybrid vehicles. Compare to traditional gaseous state vehicles, hybrid vehicles emit 97 per cent lesser of carbon, save 169 gallons of gasoline each year and its car batteries bed last about ten years. (Taheshea, n.d.)The lesser amount of carbon dioxide emission can help to prevent hot rain, global warming. Carbon dioxide reacts with rain water to form carbonic acid which suit of clothess acid rain to occur. Highly acidity rain can affect the sea life by impenetrable the pH value of sea water, forest on the world due to the highly acidic priming that is not suitable for the plant to grow and human health by drinking contaminated water. (Oracle, n.d.) By reducing the amount of carbon dioxide emitted to the atmosphere, less carbon dioxide can react with rain water and abbreviate the acidity of rain water. Thus, it can protect the welfare of the environment as well as human being. Since carbon dioxide is the major type of greenhouse gasses that trapped heat energy within the Earth and cause global warming to occur, ac cording to Global Commons Institutes, if the total carbon dioxide emission decrease about 2.5 per cent per year, it can definitely slow down the process of global warming by 10 years. (Cooper, n.d.) Thus, the issues such as biodiversity of plants and animals and extinctions of endanger species that cause by global warming can be prevented. (Britannica, n.d.) crossbreeding car can save about 169 gallons of gasoline per year. Non-renewable sources of energy such as gasoline and oil colour can be prevented from over exploitation by using hybrid car as an alternative vehicle. (Cars Direct, n.d.) Besides that, hybrid vehicles use lesser amount of gasoline. It emits less gas fumes and carbon dioxide to the atmosphere. (Car Direct, n.d.) Therefore, the mental strain in the atmosphere can be cleaner and contain more breathable oxygen. With a cleaner and breathable air, it can prevent human being from respiratory diseases such as asthma and reducing the death rate due to respiratory diseas es. Lastly, hybrid car helps in reducing the noise pollutions in the environment as well. This is because the engine of hybrid cars only churning the amount of horsepower required and without any extra roaring. When it is changed to electric power mode, the cars operate silently compare to traditional gasoline consumption car. (Buzzle, n.d.)Therefore, green technology brings several benefits to the environment such as preventing acid rain and global warming, protecting the plants, animals as well as human being, providing cleaner and breathable air and reducing noise pollution.

Examining The Revolution Of Internet Usage Media Essay

Examining The Revolution Of Internet Usage Media examineInternet hold has brought revolution in parley. In the recent past, thither has been advancement lucre technology making cyberspace to a greater extent fond to many pluralitys. In business and institutions net chat has brought major changes to how communication is made. One of the major effects of net income is making nurture more get atible to most battalion. Although this has been highly praised, it has brought questions on regulation on usage of meshing. In the recent past families, organizations, institutions, interest groups and even g overnments accept been trade for lucre security review. Internet censorship erect perplex positive usurpation depending on context.New technological bases have led to the introduction of cyberspace work which play a major role in the valet of communication. The net income provides an appropriate forum, where people can communicate with one both(prenominal) for mer(a) regardless of their geographical location. Due to minimal regional restriction on internet go, people from virtu e truly(prenominal)y all ages with internet knowledge in most part of the world can easily find it. Conventionally, internet was a communication tool that mainly consisted of e-mail inspection and repair. Internet characterrs electrostatic sign up for engagementr accounts through which they receive and send e-mails to other registered users (Foerstel 120). Since the modifications of original internet user configurations, internet has significantly improved in its functions as it provides a wide array of options in both clubby and commercial websites with a lot of randomness.North Korea is considered among the top blog-unfriendly nations in the world due to internet censorship. It is only the foreigners and politically privileged people who atomic number 18 allowed to access the internet freely in the ground. Consequently, there is no openly existent blog in subscribeing to heavyies by North Koreans to access blogs. Journalists argon allowed by the government of North Korea into the country on originator that they are followed around by watchers to ensure they do non fluff in suspicious activities. The government besides carries out censorship on intelligence info before it is made public hence control over all tuition that the citizens receive (Icon Group International, Inc. 39). In Pakistan, self censorship by media companies started with the reign of General Zia who was both the president and army question (Icon Group International, Inc. 48). In this form of censorship, press cloth is checked so that the governments credibility is not tarnished. All press material in Pakistan moldiness favor the government of the day to ensure political serenity in the country.In Guilford County, North Carolina, initial plans to ban two books The Color imperial and Native Son that were used in teaching literature in the curriculum fa ced a petition to eliminate them from the course compute and won. This was as a result of a censorship policy which was aimed at employ package and other gist to restrict pornographic material from being accessed from online sources or school libraries, a move that was considered unconstitutional (Foerstel 207). shoal boards in Lima, Ohio and capital of Mississippi County in Ripley unanimously voted against this form of censorship by the twelvemonth 1999. At the same period, The Color Purple was eliminated from the curriculum and libraries at Ferguson High School in Virginia (Foerstel 207) due to claims of vulgar language and explicit content.This form of internet restriction was received as an unappreciative move of eliminating library material for scholars. As a result of the censorship move gaining negative response, law figure outrs alert spick-and-span and better rules that allowed scholars to obtain online selective information without the boundaries censorship caused as a result of anticipateing public obscenity displays through the internet (Foerstel 114).The internet came with a myriad of challenges and in some cases, unique set of unanticipated drawbacks besides came forming its disadvantages. Based on extreme case scenarios, this essay seeks to argue against the finishing of censorship policies to information sources on the internet. It goes ahead to suggest the alternate(a) expect for better protection policies that favor both the users and controlling bodies before finalizing on the extent of its applicability if deemed necessary.Sandra Hughes of CBS news reports of Robert Wise, an online raise predator who preys on a 14 year old girl and later on gets arrested for soliciting for sex from a minor unfolding the dangers of unrestricted online communication between diverse parties. The CBS reporter further gives an account of the story of Kyla Reed, a 15 year old who goes missing without a trace after being an prompt participant in My Space. Investigations link her disappearance to her activities on the cordial earnings (Kreiser 7). The culmination of such stories is a likely evidence that would arouse governments to express censorship of the internet. This would further not put an end to the activities of predators as they would expand them out elsewhere. It is a pet option to innovate alternative means of preventing online predators.Various aspects of socialization can be attributed to interactions through the internet that have improved communication among different users of the web. This has been made come-at-able by internet service developers inventing ways of configuring more sophisticated services such as voice over internet protocols and instant messaging services that coat way for the creation of highly interactive web sites. Presently, Face book, MySpace and twitter are the leading social internet sites which use chats as the latest culmination of instant messaging service among other opti ons for internet communication. much(prenominal) web sites reflect on the need to have communication radical which appreciates urgency and convenience, the limitations in the physical environment notwithstanding. Restricted internet use would bar intercommunication among people of different cultures thus deterring the build up of social ties and should be avoided where applicable.Internet usage is more and more be approach a demand to users who spend most of their date searching for information that is to be use in either personal or professional use. Internet also plays a fundamental role in the media fraternity as it is a means of sending and receiving both local and external news (Jones 19). Basing on this, communication is made much easier for journalists because they have access to vital information through the internet and a ready audience. CBS and other news networks have links on Face book, Tweeter and MySpace to keep track of its audience for information dissemination . With new innovations, there were introductions of updated journals in form of blogs which provided diverse information. Journalists are however criticized by scholars as being supposedly cynical in their work which brings intimately the claim of lack of professionalism.Jones weblog on Real and fake news shows the criticism reporters receive from the public and intellectuals for what they term as ir indebtedness caused by bias in reporting. They brand this as the main reason for the puppyish people being politically ill informed as a result of turning to non credible or single sided sources of information (Jones 20). such(prenominal) political content in news makes authorities have reason to ground a basis for information censorship.Positively impacting sites include those which are educative and informative in terms of providing essential academic materials to users. In addition, many people use online services to communicate with people crossways the continent. At present, com munication is much easier through the internet because people can easily chat from sites of social networks. Apart from education and communication purposes, the internet has gained popularity because of its entertainment nature as users can play games, download pictures, melody and movies (Contrada 117). Despite the many benefits derived from internet use, there has been a realization of some setbacks. Internet can negatively influence users since it at times contains offending and explicit materials. At a very rampant rate, sexual sites with pornographic content are frequently visited by people of different ages including minor(ip) children out of curiosity or ignorance. Regardless of parental monitoring, it is very difficult to control what children do opus using computers. For this reason, there are controversies on what basis the internet should be censored (Farhi 5).Due to high levels of possible risks that unsafe internet users are predisposed to, censoring online servic es is increasingly becoming a preference to authorities since it promises protection to its users from the proliferation of mal employs such as sexual exploitation. illegalise is seen as a probable root word that would thus wait on parents who have difficult time in controlling their childrens access to pornographic sites that display distorting material oblivious of what their effects may be. Similarly, the full point of devastating effects that it has on the users is deliberately ignored by the hosts to the outrage of the society.Even though censoring of internet content may not have a major influence on the amount of responsibility adults practice on the vulnerable group, it is important to control unsociable internet activities like contour trafficking (Chawki Wahab 1). People specially, women and children often fall into the trap of military personnel traffickers who advertise themselves and conduct most of their practices through the sites. Without knowing many peopl e are blindly lured into such illegal practices since it is sometimes difficult to label the credibility of a given site due to their persuasive nature. To help curb these cases, censorship may seem to be a preferable option. However, governments involved should come up with new ways of monitoring the use of internet curiously in criminal activities such as human trafficking (Chawki Wahab 4).In relation to e-mail services, censoring the internet would prevent users from lawlessly accessing unlicenced information. E-mail intruders would and so have a difficult time in acquiring information once the internet is censored. In addition, censoring internet information testament help detect and prevent behaviors and habits of users with venomed motives. This is likely to save the society a lot of social problems that lead to loss of moral wellbeing. The main reason is that all undesirable information is crushed automatically when the internet is censored. Furthermore, users are prot ected from hate mails or any other information from the populace that leads to negative effects. security review the internet can be beneficial since it get out ensure control of the kind of material that people access such as government information. These administrative bodies are usually strict when it comes to secrets and will always try to enshroud vital records from the public. Although there are ways of concealing information, some individuals will work out ways of accessing such records through the web. Arresting such people may not be a permanent solution because others might continue with the trend. Effective innovative ways to detect and prevent these malicious acts would be a useful remedy to the governments since the public will not succeed in acquiring any secrets (Drezner 34).Although censoring the internet can be advantageous, it may deny non-targeted individuals the opportunity of accessing important information (Contrada 83). Internet should not be censored becaus e it may prevent people from getting vital information. Such information as educative content, scientific information based on recent studies may lead to new ideas that could be hidden from users. Therefore, censoring internet sources is likely to hinder innovation and new discoveries because the means of acquiring new and supportive information is complicated.Censoring the internet can also be a disadvantage to individuals as they would not get the opportunity to express themselves. Internet is a indicate where people can openly express themselves to other people. Furthermore, it is also a place where people can learn about the views of others. By restrict online services, free interaction would be hindered. To a certain level, a peculiar(prenominal) government can benefit from internet restrictions although it would be at the cost of its citizens (Contrada 64). This means that internet censoring is seen as only benefiting the government while its citizens suffer. Such a govern ment risks being viewed as overly oppressive.In most cases, censoring internet sources may appear like denying citizens the make up to information. People have the need to meet knowledge about all changes that are happening around them and in other places. Restricting online services will also prevent them from knowing important information about the government. It is not fair to put people in the dark especially when there are difficulties in the country. Societies are part of a country and so should be updated of various issues within the nation (Contrada 32). Moreover, censoring the internet would prevent the media from accessing and conveyancing essential information to citizens by the government. There should be freedom of the press whereby journalists can express themselves without any restrictions. Once online services are restricted, journalists may be unable to even access international news. In America, restricting the internet would go against the 1st Amendment right w hich states that there should be freedom of speech and press (Drezner 33).Globalization is increasingly changing the world of communication as there are new technologies which make interactions much easier. Internet communication is considered as one of the major sources of information to the media fraternity both locally and internationally. Censoring the internet may therefore limit the manner in which the media sends information to its target consumers and limit intercultural communication which is widely done through the web. Journalists are frequent internet users as they receive and convey information through different sites.Journalists prefer using blogs because it is a quick method of information dissemination especially when conveying urgent and important information. Through blog sites, journalists are able to hash out a wide range of topics which including politics, economy, environment, finance and many more. More often, journalists use online services to publish polit ical issues that may affect their country or other countries. If the internet is censored, it would not be possible for people to acquire certain information about political issues. Online services should not be censored because it would prevent journalists from hosting and visiting blog sites that are very essential to them. Apart from blogs, journalists normally visit social networks which they use due to their devalued nature and popularity in information conveyance. Journalists also prefer the site especially for stories that are changing so fast such as the cultivation of a report on survivors of a plane crash. Mainstream media depends on such information since collection and encoding can be done fast. (Farhi 3).Primarily, internet plays an essential role in the world of communication. Through the internet, people are able to communicate with one another regardless of their geographical locations. Online service is therefore one of the major source of information to media fra ternity. (Rosen 3). Although internet is very useful to genuine users, it also has limitations since it is characterized by sites that contain sexual materials.Censoring the internet has been made necessary owing to the need for keeping unauthorized individuals at bay through blocking access to sites by users who cannot practice self censorship as a result of ignorance or curiosity. The demerits arising from all-embracing internet use can however be curbed by coming up with monitoring policies that protect and prevent vulnerable groups. This is mainly because censorship would deny genuine internet users the opportunity to acquire information from a variety of sources. A better recommendation would be to develop alternative internet policies that permit users to access specific sites on the internet. This would protect vulnerable groups from exploitation by malicious people thus enhancing the security of the state.

What is a Good Life?

What is a Good Life? world universes have an inherent drive and displeasure for finding absolution in what they deem the intimately bread and just nowter history.For decades however, philosophers have strugg lead to turn over a solid case for such. It croupe be suggested that m whatever facets imprint in unison to allow a well behaved demeanor, but what is it that could spread a unified answer to this great philosophical question? This act give attempt to clarify such uncertainty, con emplacementring deuce perspectives of the proper life.Firstly, be there any characteristics, needs, abilities and sorted other ele workforcets that atomic number 18 shargond by all gays? Secondly, if there atomic number 18 elements which exist, then what do these use up the effectual life to include, or what mustiness the good life be like, given the properties we all share? To distinguish the answers to these questions, reference allow for be given to Natural Law, legality The ory, Eudaemonia and cheer.We are all pains towards it, the good life, merriment, well- world, a well-lived life, fulfilment. But what is it that makes us feel good? though difficult to give a comprehensible definition, worth is generally referred to as specific traits or properties of a real object or mark off of objects. More so, the concept of goodness can be divided into other, auxiliary concepts (Goodness and Value Theory, 2004). That is, a series of gather up downts which lead to innate goodness. In essence, both(prenominal) are deemed circular and leave no meaningful definition for discussion.The good life is a condition in which a mortal bequeath be the most happy. such joy can be researched by means of a deductive perspective, which has been done by many philosophers over sentence (Wernqvist, 2007). Two such philosophers, Plato and Aristotle, deem the good life as the res publica in which a person exhibits total right. Throughout this es imagine, their work s will be compared and contrasted to give clear argument to the meaning a good life for gentleman.Humans, their characteristics and their activities can be evaluated in relation to the parts they assemble in human life (Meyers-Levy, 2009). Alternatively saying, that every facet of human life can contribute to what is deemed good. Humans, being a subject of creation, last entail goodness. Such a life is one in which actions someone does and feels leads to what is otherwise known as gaiety. Such merriment is neither retributory an experience nor is it found as a result of following clean laws. Rather, happiness is an activity. It is the events of the individual which lead to the life of good. INSERT REFERENCE everywhere time, philosophers such as Plato and Aristotle have tried to highlight the concept of goodness by def fireing various accounts. Such accounts do non rent that a person who is well off only when experience any feelings of happiness or satisfaction. What they do require is that their desires are consciously accomplish, which does non come down to the identical thing (Angner, 2009).Plato argues that a person will exhibit total virtue when their desires have been quenched ( make and Hutchison, 1997), while Aristotle believes the utter(a) state of the individual will bring their ultimate virtue (Solomon, 1984).Cooper and Hutchinson (1997) write that Platos argument for the good life is stemmed from admire be ride done this, individuals can rid themselves of desires. That is, lie with is actually the quest for that good. Aristotle argues that the good life is different for each(prenominal) individual because it comes from living ones life according to ones virtues, and each person has different virtues (Solomon, 1984).Through analysis of their works, both Plato and Aristotle agree the good life is a demonstration of perfect virtue. However, they take issue on the ill-tempered definition of virtue and its relationship to happiness. therefore, both disagree on the ship canal of seduceing such happiness.Plato travel tos the good life as being attained finished the perfect love and lack of desire (Cooper and Hutchinson, 1997), while Aristotle believes that the good life is succeedd through a perfect state which causes its citizens to act upon their virtues (Solomon, 1984).The original Platonic becharm of the world, (cited Cooper and Hutchinson, 1997) is that it is a two graded place, the upper tier being the world of perfection, the lower tier being the world of reality, and love authorizeing somewhere in surrounded by. The surmise is that the plane of reality is an imperfect copy of the plane of perfection. correspond to the Platonic view, humans only see glimpses of the good while existing in the plane of reality.Plato believes that love is the core between reality and perfection, mortality and immortality. Love does not fall into the battlefield of immortals and perfection because how could lov e be a idol if he is not in possession of bonnie and good things? Since Love is the love of beautiful things, Love must have desires and therefore cannot be a god Yet Love is greater than mortals because love has and always will exist. therefore Love is a great spirit, a halfway point between the realms of existence (Cooper and Hutchinson, 1997).To Plato, the good life is one in which a person is exhibits perfect virtue and is therefore closer to the higher realm of existence. Virtue is comes from the absence of desires, so true happiness means being at ease to the point one does not have desires. This satisfaction and happiness bechance when a person arrives at the mystical understanding of the world (Cooper and Hutchinson, 1997).According to Plato, through Diotima and Socrates dialogue, love is the medium in which humans will attain the knowledge of the good, and come upon this understanding. It is human nature to seek out happiness, and willpower of good things makes one ha ppy. (Cooper and Hutchinson, 1997).Solomon (1984) illustrates that in order to show that happiness lies in virtue, Aristotle first splits forms of the good into three parts, external goods, goods of the body, and goods of the soul. He goes on to say that goods of the soul (virtues) are the most important because with them, a person can gain material riches and pleasure. Aristotle defines happiness and therefore the good life as the realisation and perfect exercise of excellence. This is subsequently referred to as Eudaemonia.Aristotles view of such is typically regarded as an purpose account of well-being. Nonetheless, subjective stances do evidently play some role in well-being even according to Aristotle (Phillips, 2005). This is where the existence of goodness becomes a subjective account, because it describes a persons well-being as a function of his or her feelings, experiences, desires, and so on, thus making it a conscious attribute of human life.From a basic Greek transla tion, Eudaemonia is that of supreme life with fulfilment and happiness, identified after ones death. Such life is built of variable actions of excellence which are both inalienable and extrinsic in their nature (Urmson, 1988).Recognised, are three types of excellence by Aristotle. They are Bodily excellence, the excellence of Character and the excellence of Intelligence. Two of these excellences (character and intellect) fall within the realm of human choice and rationalism. Bodily excellence is preponderant to Eudaemonia, however exhibits little reference in this context (Urmson, 1988).There are withal a number of influences that determine such excellence, often as a result of our actions through life. Controlled intrinsic actions are separated into two forms the Moral and the Intellectual. The Moral includes ones courage, piety, fairness and equality. The other form is that of Intellectual influences which include ones fine mind, wisdom and intuition. In contrast are ones extri nsic actions, which are often uncontrollable. They include our appearance, friends in high places (social connections) and wealth (Urmson, 1988).Our actions per sae can be defined as either a chain those actions that help you attain an end which in turn leads to a further end or as a check result which is an action that helps you attain an end in itself. For supreme fulfilment, these actions work in unison with one some other (Urmson, 1988).It is through such, as detailed by Urmson (1988) that happiness and fulfilment is an objective good, as opposed to a subjective state of living. This is not conditional, but absolute (Solomon, 1984). This in layman terms means ultimate happiness occurs when a persons actions are all virtuous and have stopping points which are virtuous. It also implies that in order to live the good life, there must be no action which is unnecessary, but for the sake of virtue. This implies that the good life must be a universal goal because unless all people a re perfectly virtuous, action must be taken to maintain virtue for those who are not virtuous.Take for example, ones ambition to become a first-string School Principal. It is through germane(predicate) studies and experience that the individual is able to achieve such a goal. Though there may be pecuniary benefits for holding such position, it is not something that would drive the individual to achieve. Their character and give-and-take hold the greatest motivation for fulfilment. Such an example utilises Aristotles Eudaemonic theory of unison between chained and direct actions as well as the forms of excellence, as previously adhered to. Basing such a goal on welcome or political instincts, such as salary or power, is not a means by which Aristotle would deem leading a fulfilled Eudaemonic life.There are however three things that make men good and excellent these are nature, habit and reason (Solomon, 1984). The road to happiness is through formation of habit and reason which c reate virtuous action, in addition to possessing a nature that compliments them.Both Plato and Aristotle see happiness as being virtuous, but disagree on the nature of virtue, make their ideas to follow varied paths. They do however meet at winder points. Plato sees happiness as being close to godliness. By living morally one can obtain this godliness (Cooper and Hutchinson, 1997). To Aristotle, happiness is the result of being virtuous because by being so, one obtains pleasure and external wealth (Solomon, 1984).Plato and Aristotle further agree that fostering is the means to attain virtue, but they disagree on how a person should be educated because of their differing views on the cause of virtue.According to Aristotle (Solomon, 1984), virtue comes from the agreement of the nature, habits and reason in a humans conscience. Therefore, Aristotle states that education should begin from birth and it should involve changing the childs habits and forming his reason so that their natu re, habits and reason will align.Plato believes that virtue stems from an understanding of true Beauty, which exists only in the higher plane of the world. Thus Plato believes that education of a human being should begin when the child is ready to love another. Platos ideal education involves saving a person along by having him experience different forms of love between people, so that he may begin to love fleshly violator and then beauty of the mind. Through this he sees the beauty in all things and eventually, with guidance understands all forms of beauty, ultimately understanding formless beauty (Cooper and Hutchinson, 1997).Another key agreement between Plato and Aristotle is the importance of interpersonal relationships in the quest for the good life. Both agree that interpersonal relationships account for the education of individuals, but Aristotle goes further because he sees attaining the good life as societal.He recognizes that if one is forced to take action because of others misdeeds, he cannot lead the good life, and therefore each person must be equal to the contiguous so that nobody has to act on account of another (Cooper and Hutchinson, 1997).Human happiness is the foremost concern for both Plato and Aristotle in their works of literature. Since happiness is almost a universal emotion their conclusions on the cause of happiness is similar. But, Plato and Aristotle are completely different individuals, so the causes of their happiness are, at the same time, completely different.In personal evaluation, I am inclined to side with Aristotles point of view for ultimate fulfilment. It is through the result of actions of excellence (both direct and chained) that we can demonstrate our way of life. This in turn fortifies perceptions of us having led a fulfilled and happy life. If one opted to follow fulfilment through mere pleasurable circumstances, i.e. because the money is good, then in Aristotles eyes, their life would be one deemed lavish, suit able for beasts pulled by desire and compulsion. Happiness cannot be determined on material things. It is a matter of setting a goal and looking past the superficial things that stand in the way. It is therefore relevant to say that to lead a flourishing life, one needs to take ownership of the actions which lead to their lifelong goal. Actions often speak louder than words do. We as humans should do whatever it takes to produce the most fulfilment for ourselves. There is a distinct difference between feeling happy and merely being happy.

What Is Disturbance In The Natural Environment Environmental Sciences Essay

What Is solicitude In The Natural Environment Environmental Sciences EssayDisturbance whoremaster involve any factor which disrupts ecosystem function by mend environmental conditions (wiki). The Intermediate Disturbance Hypothesis (IDH) states that in ordinance to perfect local anesthetic species diversity, ecological incumbrance must hail at a moderate frequency (wiki). Disturbance can vary in severity, go at several temporal and spatial scales and be a conclusion of natural or anthropogenic events (www.nature).Natural stochasticity (e.g. fires, floods, volcanic eruptions) a good deal prevents populations from reaching their carrying capacity (Wiens 1984 DeAngelis Waterhouse 1987 Pickett et al. 1992 Ecol conjecture). Anthropogenic disturbance ,however, has a larger hurtful impact on habitat. In the past, the influence of humans on ecosystems has been trammel yet modern impacts fuddle more recently accelerated in gravity and range (wiki). Anthropogenic disturbance c an change and maltreat habitat, alter ecological function and increase the probability of invasive species (invasive Holzner et al. 1983 mill around et al. 1994). Invasive species can cause local species extinction as easily as preventing native species from being re-established (Simberloff 1990 Vitousek 1990). Once settled, the removal of these species is often challenging, as they atomic number 18 less affected by rival or predation than native species (ecol system). Anthropogenic activities can also alter natural disturbance events (e.g. flood prevention methods, control of wildfires www.nature).The respiteoration of disturbance regimes may be crucial. Restoration projects should aim to instigate or accelerate recovery after a disturbance, or to re-establish natural disturbance cycles (www.nature). It is essential to determine the take of variability which is tolerated in restored systems (Duarte 1991 Li Reynolds 1994 Horne Schnieder 1995 Palmer Poff 1997 White Wal ker 1997) and to recognise and inform the difference between natural and anthropogenic disturbance (wiki). Restored sites must be continually monitored and manipulated accordingly (ecol theory) so once a species has been established, the dimensions of natural disturbance regimes (size/intensity/ duration/seasonality etc) can be established (ecol theory). If this is not possible, restorationists should exertion to initiate deliberate disturbances which best replicate historical disturbances (wiki). It is also Copernican to note that species cannot merely be reintroduced the manner by which disturbances affect the sustainability of a restored community must also be taken into account (ecol theory). seasonEcological date is the progressive change in the composition and interactions of a community over time (Putnam 1994 ecol theory). After a disturbance occurs, an ecosystem result have a fairly simple level of organisation (few predominate species)(wiki). Given time, the communi ty will develop to be more tortuous (numerous interdependent species)(wiki).Restoration can occur passively or actively. static restoration allows succession to occur naturally, once the origin of disturbance has been eliminated (nature). combat-ready restoration involves more human input. In mildly or moderately disturbed habitats, restorationists may try to increase the rate of natural succession. In other words, allow the community to develop in the same centering as it would naturally, but assisting it to reach the final stage more cursorily (ecol theory). However, in critically disturbed habitats, more concentrated efforts may be necessary and environmental conditions may need to be recreated to facilitate the processes of succession (wiki). Under these circumstances, restorationists may overlook early stages of succession in order to establish late successional species sooner (ecol theory). In some cases, underlying damage, such(prenominal) as soil damage, may also requir e restoration forward the later stages of succession can begin (Whisenant 1999 ecol of rest).It has been install that succession theory is not always appropriate (Connell Slatyer 1977 ecol theory) Community patterns are often comfortably un sure due to two disturbances and stochastic events (Fisher 1983 Levin 1989 Roughgarden 1989 ecol theory). As a result, successional theory has been deemed irrelevant in several systems (Roughgarden et al. 1987 Olafsson et al. 1994 ecol theory).Assuming it allows the prediction of community patterns, the noesis of succession theory may be essential to restoration environmental science (ecol theory). In systems with strong interactions between species and rare or highly predictable disturbances this has been found to be particularly true as community approach is principally ruled by local interactions (ecol theory).Species Interactions predation/herbivory/mutualism/competition/Community Assembly TheoryLandscape ecologyThe study of pro cesses that occur across distinct landscapes and the abiotic and biotic responses to these processes is known as landscape ecology (Turner 1989 linking rest). The need for the study of landscape ecology has arisen due to anthropogenic alterations to habitats (Linking rest). patch up isolation, contiguity, size and shape (in terms of complexity) are all features which can be used to describe a landscape and these have all been found to have a large impact on both zoology and plant populations (Turner Gardner 1990 Robbins Bell 1994 linking rest).According to the theory of island biogeography, populations are most liable(predicate) to become extinct if a habitat is small and/or apart(p) from other populations. One of the assumptions of this theory states that the area between patches of habitat is both hostile and reproducible. This theory assumes that the area between habitat patches (matrix) is both uniform and inhospitable. (Previous studies have suggested that the organisat ion of habitat types in a matrix can influence the movement of organisms and/or the role of landscapes (Gustafson Gardner 1996 linking rest).)Small and disjointed habitats are also more susceptible to the detrimental effects of habitat atomization (nature). Habitat fragmentation occurs when a habitat becomes disconnected as a result of anthropogenic or natural events (nature). This causes the formation of small isolated patches of suitable habitat (nature). These habitats have a lower carrying capacity and have decreased species diversity and are therefore more vulnerable to inbreeding and local extinction (nature). As well as this, fragmentation increases the proportion of move on and decreases the gap between edges (nature). Edge effects may alter environmental factors, in turn affecting the flux of organisms and other substances across landscapes (Holland et al. 1991 and references indoors Robinson et al. 1992). Systems are sometimes dependent on the flow of individuals betw een habitats. This sustains the community structure, implying that fragmentation can influence recruitment and therefore affect the resiliency of communities (Palmer et al. 1997 linking rest). The role of restoration usually involves improving connectivity between patches by constructing or re-establishing links. This may be done with the use of corridors or stepping stones.Ecosystem FunctionEcol of rest nutritive and energy fluxes are essential components of ecosystem function and stability at a range of spatial and temporal scales (Ehrenfeld Toth 1997 Aronson et al. 1998 Bedford 1999 Peterson Lipcius 2003).Ecosystemfunction describes the foundational processes of natural systems, including nutrient cycles and energy fluxes. These processes are the most basic and essential components of ecosystems. An understanding of the well(p) complexity and intricacies of these cycles is necessary to address any ecological processes that may be degraded. A functional ecosystem, that is com pletely self-perpetuating (i.e. no management required), is the ultimate goal of restorative efforts. Because theseecosystemfunctions areemergent propertiesof the system as a whole, observe and management are crucial for the long-term stability of an ecosystem.

An aseptic technique

An infertile proficiencyInt poleuction unfertile means to be free from micro- existences. Aseptic proficiency is the procedure that is per coordinateed under stereotyped condition to baffle the growth of some new(prenominal) microorganisms on the growth medium much(prenominal) as the Petri dishes containing the food agar-agar-agar or the unmingled refinement. If the growth medium or the pure subtlety is contaminated with microorganisms from the environment, it forget topics in confusion and inaccurate data. Hence, it is important to swerve the risks of these microorganisms to come in contact with the experimental materials.In addition, by maintaining a clean environment when transferring the burnish of microorganism onto the nutrient agar is break away of the aseptic proficiency. This is usu totallyy d 1 by disinfecting the t adapted in the beginning and later on working with microorganism employ alcohol. Flaming the experimental materials such as bacteriologica l coils, bottle or flask necks standnister help in sterilizing. It must be d angiotensin-converting enzyme for several seconds so as to bear witness the temperature to rung thumbs down the contaminants however, the bacteriological loop must be cooled for a objet dart to begin with it is utilise to pick up the microorganism as pick up microorganism with a hot brute result kill the stalls. When removing caps from bottles, it is important to keep the cap in the hand as by putting them on the table, it pull up stakes be contaminated. Flaming is as well necessitate before replacing the cap onto the bottle. It is important to handle open thermionic vacuum tubes at an angle so that airborne and other microorganisms will non smooth into the tube and cause contamination. During streaking, it is important to keep the lids of the Petri dish over it to baffle contamination. Lastly, try to avoid breathing, coughing, sneezing and talking while transferring the culture so as t o reduce the risk on contaminating.Apart from this general aseptic technique, there also several other methods to ensure that destruction of aliveness microorganisms in materials and apparatus. One of the methods is by using dry heat which is sterilising using naked flame or hot air. Sterilising materials or apparatus by a naked flame is normally heated to redness and allowed to cool. They ar usually made of metal. Exposure to hot air helps to destroy microorganisms in glass and porcelain apparatus.The other method is sterilizing using moist heat which tin be used in three contrastive ways which argon warming in water or steam at 100oC, heating in steam under pressure and discontinue heating at low temperature. The different ways be employed according to the different materials or apparatus used.The last method is by using chemical, it fag be either in liquid or gaseous state. They atomic quash 18 often used in the electric pig of contaminated materials and apparatus sub sequentlywards a laboratory session.Microorganisms worked with in a lab should non be released into the environment as these strains may contain genetic markers such as antibiotic resistance. Therefore, they must be discarded properly.In addition, aseptic technique is non only applied in laboratory, it is also applied in clinical and surgical setting.AimsThere are deuce aims in this experiment. The int terminaluctory aim is to show that a large number of microorganisms exist on the surface of our hands. The second aim is carry out the aseptic technique properly by transferring pure culture and inoculating them onto an agar plate.Materials and Methodsbacteria on skin cheer arouse to the science laboratory manual(a) unless otherwise stated of changes made.Streak PlatePlease refer to the Laboratory Manual unless otherwise stated of changes made.A fluid sterile bacteriological loop is use instead of the metal sterile bacteriological loop so no heating is required.DiscussionBac teria on skinThe serviceman skins surface do carry a large number of microorganism and that by washing hands, respective(prenominal) can reduce the number of microorganism noticeably. However, even subsequently(prenominal) a hand wash, microorganisms are still bring out on the surface.Streak PlateBy employing the streaking technique on an agar plate correctly, a unmarried colony can be obtained. Furthermore, it can be used to separate colonies of mixed culture. Hence, this pure colony can be picked up and to be grown in large quantity. From the result above, it can be bumpd that single colonies of the S.aureus are found. Due to the vividness and morphology, it can be noted that the S.aureus is of a pure culture.ConclusionAseptic technique is a staple laboratory technique that must be employed curiously during Microbiology laboratory session so as to prevent any contamination and affecting the accuracy of the result. Since microorganism can replicated rapidly, disposal of co ntaminants must be done properly so as to hold dear both the equipments and the health of individuals.B- constant of gravitation fleckIntroductiondeoxyguanosine monophosphate fall guy is also cognise as differential stain in which it will divide bacteria into two large groupings, mainly universal gravitational constant cocksure and Gram ostracize. This difference is due to the chemical and physical structure of the cell rampart called peptidoglycan. During solvent treatment, if the peptidoglycan is able to retain the quartz glass violet dye, the bacteria will be group as Gram Positive bacteria. However, if it is not able to retain the lechatelierite violet, the bacteria will be group as Gram Negative bacteria and that it will be stain pink.Gram Positive bacteria has a thicker peptidoglycan (50-90% cell wall) as compared to the Gram Negative bacteria (10% cell wall). In addition, the Gram Negative bacteria has another mould which is make up of liposaccharides and protei ns and is separated from the cell wall by the periplasm.In chiliad staining, there are four basic steps which include flooding the heat fixed smear with crystal violet stain, following by the addition of iodine solution to form complex, adding of alcohol for decolourisation and comeerstaining with safranin.After flooding the peptidoglycan with crystal violet stain, the dye will enter the cells and all cells will turn purple. With the addition of iodine, a crystal violet-iodine complex will be form such that it will not be able to exit the cells easily. By decolourizing the cell with alcohol, the peptidoglycan of the Gram Negative bacteria will break down because the alcohol will dissolves the liposaccharides layer and hence, with the removal of the layer, the crystal violet-iodine complex will run off which will results in the loss of the crystal violet stain and the cells turn colourless. On the other hand, the alcohol will dehydrate the Gram Positive bacterias peptidoglycan, bl ock the pores as the peptidoglycan shrinks. As a result, the crystal violet-iodine complex will not be able to run off as the exits will be blocked and they remained stain. By find outerstaining with safranin, the Gram Negative cell will turn pink and the Gram Positive cells will remain violet. With gram staining, one is able to differentiate if the culture is a pure or a mixed, the morphological details of the bacteria and the arrangement of the bacteria.AimsThe aim is to prepare smears for staining, observe the morphological details of the bacteria and to be able to differentiate in the midst of Gram Positive and Gram Negative bacteria.Materials and MethodsPrepa symmetryn of Smears for stainingPlease refer to the Laboratory Manual unless otherwise stated of changes made.A disposable sterile bacteriological loop is use instead of the metal sterile bacteriological loop so no heating is required.Gram Staining MethodPlease refer to the Laboratory Manual unless otherwise stated of c hanges made.DiscussionAccording to the result sight, Bacillus subtilis is rod shaped (bacillus). They are stained purple which suggests that they are Gram Positive bacteria. They are ordered in singles. Although, endospore cannot be observe in this experiment, they can also be found on Bacillus subtilis. The endospore enables the bacteria to tolerate harsh environmental condition such as high temperature. Bacillus subtilis can also be known as a single bacillus bacterium.Escherichia coli is stained pink and thereby, it is a Gram Negative bacterium. The cells are also rod shaped but they do not pretend any situation cell arrangement. They are found in singles, pairs and even clusters.Proteus vulgaris is also stained pink and hence, a Gram Negative bacterium. Its morphology rod shaped and is arranged in singles. They can also be known as a single bacillus bacterium.Staphylococcus aureus is a Gram Positive bacterium as it is stained dark purple after gram staining. It has a spherica l shaped, otherwise known cocci and they are usually arranged in grape-like clusters. Therefore, they are known as a staphylococci bacterium. There were no differences in the shape and colour notice for apiece of the bacteria, hence, they can be known as a pure culture.ConclusionThe Gram staining method is a useful tool used in most laboratories as it helps individual to visualise the bacteria accurately and effectively such as the shape, arrangement and even whether the culture is a pure or mixed.However, it should be noted that not all bacteria will discontinue a gram reaction as some of them are gram variable, otherwise known as gram indeterminate. Therefore, they will make pass a mix of pink and purple cells after gram staining. For some of the Gram Positive bacteria, their peptidoglycan breaks easily during cell division, hence, after staining, they will give pink cells instead of purple. In addition, the duration of a culture can also affect the gram stain.C- cell findI ntroductionCells run is the accurate and precise numeration of cells. They are usually carried out manually or electronically. By casting cells manually, a counting bedroom, otherwise known as the haemocytometer is used. The counting chamber is used to crack the number of cells per unit volume of a breakage. On the other hand, a coulter counter is used to count cells electronically.There are two approaches to count the number of cells, mainly total cell counts and the feasible counts. center cell counts are counted directly using the microscope and that both living and suddenly cells are counted. This is normally accompanied by the use of the counting chamber or coulter counter. Another approach is the viable counts which only count the living cells. The small volume of culture, otherwise known as the dilution of the culture is applied to the surface of an agar plate. After incubating, the colonies are counted, normally colonies surrounded by 30- three hundred are chosen to be used for the calculation of niggardliness of the condition prototype. The units given is colony forming units (CFU) per ml. The haemocytometer is a modified glass slides with two count chamber of known area. Each chamber grid is composed of golf club squares which are known as subgrid, each square is 1mm2. Within each large square, there are further sub divisions that help in counting. When the coverslip is placed over the grooves of the slide, there will be a thickness of 0.1mm. Hence, the volume is 0.1mm3 or 1 x 10-4ml. Therefore, the cell concentration will be calculated as the number of cells multiply by 1 x 104ml and again, multiplying the dilution factor.Since cells are real small and they can be observed in a very high number, the suspensions should be curvedd fair to middling so that the cells are able to distribute samely in the counting chamber.AimsThere are two aims in this experiment. Firstly, to be able to image the cell count in different biological spe cies and secondly, to be able to determine the viable count of a live bacteria, Staphylococcus aureus.Materials and MethodsCell ciphering using Counting ChamberPlease refer to the Laboratory Manual unless otherwise stated of changes made.Serial Dilution is carried out before the example is loaded into the Neubauer Manual Counting Chamber. Normal saline (0.9% NaCl) is used to dilute the blood and broth medium is used to dilute the brewers barm ( genus Saccharomyces cervisiae). Both blood and brewers yeast are dilute in the ratio of 110 and 1100. The 110 dilution is prepared by diluting the 10L of whole blood or yeast with 90L normal saline or broth medium individually. The 1100 dilution is prepared by extracting 10L from the respective sample from 110 and adding 90L of normal saline and yeast into the respective sample. Cell Counting of Live Bacteria, S. aureus (after Serial Dilution)Please refer to the Laboratory Manual unless otherwise stated of changes made.Two changes were ma de in Step 1 and Step 12 respectively.Only three nutrient agar plates , 10-3, 10-4 and 10-5 were labelled and culture in these dilutions were spread on the respective agar plates. A new spreader and pipette tip were used everything a different dilution culture was spread on the agar plate. Count the number of colonies on the three different agar plates. Choose the agar plate with colonies between 30-300 to calculate the concentration of the original sample.Discussion development the counter chamber, individual is able to give a quick judging on the number of cells given that all the procedure on preparing and load up the sample onto it. One of it is that suspension/sample is not mixed before loading. This is due to the fact that cells tend to settle at the bottom of the tube and hence, while pipetting the sample out from the tube, individual do not draw the actual or accurate number of cells. Therefore, to get a uniform suspension for a more accurate result, mixing the tube befor e pipetting is recommended. In addition, it can also help in reducing the clumping of cells.Furthermore, untoward fill up of chambers can lead to inaccurate volume of suspension in the chamber and leading to inaccurate cell concentration. Improper filling of chamber includes overfilling or under filling of sample.Moreover, there must be a consistency in counting cells which is in contact with the boundary lines (ie. the three lines just outside the grid) or when the cells are clump in concert. separate will have to determine which cells to count and which not to count especially a cell which is situated on a border such as if a cell has half of its area outside the border, individual do not count those cells.The other method of cell counting is the viable count where a single cell will give rise to a colony which is visible to the naked eyes on the agar plate. Therefore, by counting the number of colonies on the agar plate, individual is able calculate the cell concentration. Ho wever, only plates which have 30 to 300 colonies are used to calculate the cell concentration.In the result for viable count of S.aureus, the plate chosen was 10-5 because there was 82 colonies in one quadrant which is equivalent to 328 (82 x 4) colonies on the agar plate. Although, the number of colonies (328) go through the number of colonies of 300 that we were supposed to chose, this 10-5 dilution plate has the closest number to 300. However, we should dilute even further because a single colony can have clumps or chain of cells in it and hence, resulting in inaccurate number of colonies/cells in which the actual number of cells should actually be more than the calculated number of cells.The advantage of viable cell counting is that the organism counted will be a positive one (ie. S.aureus) instead of any other organism as if there is contaminant, the morphology or colour will be different.Another disadvantage of viable cell counting, other than cells that clump together or hav e chains which will form a single colony, is that organism will only grow in condition which is commensurate for their growth on the agar plate.Cell counting usually is accompanied by serial dilution as it is impossible to count the number of cells if the concentration is too high as it will lead to a very high number of cells.ConclusionThere are several other methods, other than using counting chamber and viable cell count, to count cells in a suspension. However, they are the least expensive and is able to give accurate result in a very short time period of time.ReferencesAbcam, 2009. Cell counts using a haemocytometer.
