Truth Is Stranger Than Fiction

Truth Is Stranger Than Fiction Professional success and personal failure of James M. Barrie In researching the many odd and bizarre happenings of our unique culture, it is certain that truth is often stranger than fiction. The first paragraph of James Barrie's classic story "Peter Pan" introduced its central theme: "All children except one, grow up. They soon know that they will grow up"‚Â ¦this is the beginning of the end." It sounds innocent enough, but a look at Barrie's life gives it a more sinister twist. Although J.M.Barrie wrote many plays and stories, it was said that "All of Barrie's life led up to the creation of Peter Pan," wrote James Merritt, one of his biographers.A pivotal point came in 1866 when James, (the ninth in a Scottish family of ten), was six years old: His brother David, the pride of the family, died in a skating accident. Barrie's mother was devastated. To comfort her, James began mimicking David's speech and imitating his mannerisms.James Matthew Barrie

Essay Example The essay, though apparently seems a difficult text for reading, has been established on firm and definite norms and objectives. â€Å"The first paragraph establishes the essays objective: to investigate technology in order to prepare us for a "free relationship" to it. One of the fundamental questions of the essay has to do with how "we†Ã¢â‚¬ ¦ currently relate to technology, how we think about it, what we imagine it to be.† (Heidegger: The Question Concerning Technology, hawaii). Thus, in an ultimate evaluation of the essay one finds the worthiness and value of it. An exceptionally remarkable aspect of the essay "The Question Concerning Technology† is that it, more than any scholarly article on the complex questions around culture and technology, has influenced several other writers and thinkers as well as it is formed on the basis of the existing paradigms and scholarly works on the similar topics. Conspicuously, the interest of the author in "The Question Conce rning Technology† falls not on technology or the various forms of it but on an orientation of the readers towards technology. The essay seems to be very relevant and valid to the modern age of technological age as it has been a relevant interpretation of the modern man in relation to the technological advanced universe. Thus, the essay also amounts large scale influence and significance among the modern writers and it has been structured rooting its arguments and thoughts on the terminology of German, Greek, and Latin. For example, we may consider â€Å"episteme,† the first word that is significant to the idea of information that Heidegger explains to the reader. It can be defined, in simple translation, as "knowledge." In an analysis of the influences that informed this significant essay, it is important to note that the interest of the writer was to orient the readers to technology and act as a tool or mediator between the

Based on the readings, what do you see as the biggest obstacles to Essay

Based on the readings, what do you see as the biggest obstacles to development of poorer nations What can be done about it - Essay Example development in these countries can be divided into four categories: Natural Resources, Human Capital, Poor Infrastructure, and institutional factors.2 However, the difference between the developing and the developed world lies in the human, physical and the socioeconomic environments of the nations in question. This paper has used different theories of development to explain the obstacle to development experienced by poor countries. Most of the poorer countries have inadequate resources including the fertile land. Availability of the resources can bring an increase in the productivity of the economy. In most developing nations, there is shortage of land due to the high population. Lesser land leads to significant fall in cultivation which is the main source of income in the poor nation. This in turn leads to the fall on the nations’ productivity known as the Gross Domestic Products.3 The situation is even worse since these countries have not tapped the technological practices in their productivity. According to the Exogenous Growth theory lack of technology makes it hard for a country to develop. Technology acquisition enables high production per unit of a natural resource like land when it comes to agriculture.4 The land in most of the developing nations is also so much fragmented due to socioeconomic issues such as passing the land to the next generation and the attempt by government to ensure equitable distribution of resources in these areas. It is good to understand that most of these nations over- depends on land which is the backbone of the developing world economy. There is therefore much tension when it comes to land issues.5 Most of the Sub Saharan African countries have vast natural resources that include oil and gold. This line of argument is in agreement with the Exogenous Growth Theory that the problem comes in the identification and affordability of technology that would help in the discovery of mineral deposits.6 This has led corrupting during

Abstract It is unfortunately true that no one single perfect leader in human history is the ideal in terms of leadership, and this means that it is impossible to define precisely the set of characteristics and skills that any leader should aspire to. However, it makes sense to try to understand better leadership and the attributes, sk ills and characteristics desired in leaders by examining that which great leaders have demonstrated through the ages because such an effort assists with the understanding of leadership and aspirations for leadership. Although leadership is an intensely human activity, leaders must strive to attain the right vision for the future of their group in an environment in which they exist with their groups and in their time. This means that the right leadership must present a regard for the complexity of organised society and the state of development of humanity to confront future challenges. Because leadership is of significance for any group and there is a shortage of talented leaders in all spheres of human activity, with unique challenges lying ahead, it is possible to gain from insights about leadership by comparing a sample of leaders of the past with a sample of modern leaders to decide about leadership and its evolution over time. This dissertation presents a comparison of Alexander the Great, King Leonidas, Napoleon, Che Guevara, Margaret Thatcher and Barack Obama as leaders to decide about leadership and the evolution of leadership.

Laminar Air-flow to Control Operating Room Infection

Laminar Air-flow to Control Operating Room Infection INTRODUCTION Surgical site infections (SSIs) are defined as infections occurring within 30 days after surgical operation or within one year if an implant is left in place and affecting either the incision or deep tissue at the operation site (Owens and Stoessel 2008). SSIs are reported as the major cause of high morbidity and mortality among post -operative patients (Weigelt et.al. 2010). According to UK National Joint Registry Report, during 2003 -2006 period infection was responsible for about 19 % failure of joint surgery resulting in revision procedures (Sandiford and skinner 2009). Micro-organisms in the air particles settle on the wound, dressings and surgical instruments and cause infections (Chow and Yang 2005). Whyte et.al (1982) identified that contamination from patients skin as the cause of infection in 2% cases and from theatre personnel in 98% cases. They also found that in 30% cases, contaminants reach the wound from theatre personnel via air and in 70% cases it is via hands. Generally air quality in the operating room is maintained ventilation system. Additional improvements can be achieved by laminar air-flow system or UV lights. Laminar air-flow system is expensive and require continues maintenance. Its installation increases building cost and the operational cost (Cacciariet.al., 2004: Hansen, 2005). Studies conducted to evaluate the effectiveness of laminar flow produced mixed results and there is no consensus on its role in infection control (Sandiford 2007). In this setting, this paper reviews the recent studies to examine the effectiveness of laminar air-flow in reducing SSIs. Studies for this review were found by searching on databases such as CINAHL, PubMed, Science Direct, Ovidsp, Science Citation Index (ISI) and Google scholar. Keywords used for this search are laminar air flow, surgical site infection, operating room air quality, airborne infections + operating theatre, LMA + infection control. As laminar air-flow is used mainly in orthopaedic theatres, majority of the studies are on joint surgery. OPERATING THEATRE AIR QUALITY AND INFECTION CONTROL Indoor air in an operating theatre contains dust which consists of substances released from disinfectant and sterilizers, respiratory droplets, insect parts smoke released from cautry. Dust particles act as a carrier for transporting microorganisms laden particles and can settle on surgical wound and there by cause infection (Neil 2005). Air particles are found to be responsible for about 80% 90% of microbial contamination (CDC 2005). Modern operating theatres are generally equipped with conventional ventilation system in which filters can remove airborne particles of size >5mm about 80-95% (Dharan 2002). The efficacy of operating room ventilation is measured by the colony forming units (CFU) of organisms present per cubic meter. The conventional ventilation (Plenum) with 20 air exchanges is considered efficient if it achieves the colony count of 35cfu/m3 or less (Bannister 2002). Ventilation system with laminar air-flow directs the air-flow in one direction and sweeps the air particle over the wound site to the exits (CDC 2003). Laminar air-flow with HEPA (High Efficiency Particulate Arrestment) filters system has the capacity to remove air particles of size 0.3  µm up to 99.9 % and can produce 300 air exchanges per hour in ultraclean orthopaedic theatres. (Sandiford and skinner 2009). Laminar air-flow units are generally two types; ceiling-mounted (vertical flow) or wall-mounted (horizontal flow). There are inconveniences associated with both types. Generally the major problem associated with laminar air-flow is flow disruption. With vertical laminar flow, it is the heat generated by surgical lamps creates air turbulence while with horizontal laminar flow it is the surgical team that disrupt the air-flow (Dharan 2002). LAMINAR AIR FLOW IN INFECTION CONTROLL Laminar air-flow system is mainly used in implant surgeries where even a small number of microorganisms can cause infection. In joint replacement surgeries, one of the main causes of early (within 3 months) and delayed (within 18 months to 2 years) deep prosthetic infections was found colonisation during surgery (Knobben 2006). Laminar air flow is supposed to minimize contamination by mobilizing uniform and large volume of clean air to the surgical area and Contaminants are flushed out instantly (Chow and Yang, 2004). Some studies found that this method is effective in reducing infection but some others produced contradicting results (give some reference) A recent study conducted by Kakwani et.al. (2007) found that laminar air-flow system is effective in reducing the reoperation rate in Austin-Moore hemiarthroplasty. Their study compared the reoperation rate between theatres with laminar air-flow and theatres without laminar air-flow system. A cohort of 435 patients who had Austin-Moore hemiarthroplasties at Good Hope Hospital in Birmingham between August 2000 and July 2004 were selected for this study. Of those 435 patients, 212 had operation in laminar air-flow theatres and 223 had operation in non-laminar air-flow theatres. Data were collected by reviewing case notes and radiographs. For all cases antibiotics were administrated and water impervious surgical gowns and drapes were used. In the non-laminar air-flow group it was found that the re-operation rate for all indication in the first year after hemiarthroplasties was 5.8 % (13/223), while in the laminar air-flow group it was 1.4% (3/212). Analysis found that there were no stat istically significant relation between re-operation rate and water impervious gown and drapes (p=0.15), while use of laminar air-flow found a statistically significant drop (p=0.0285) in re-operation rate within the first year after hemiarthroplasties. They found that re-operation rate in no-laminar air-flow theatres were four times greater than that in laminar airflow theatres. Even though the aim of the study was clearly described there was no review of existing studies to identify the gap in the research. Study methods and details of statistical analysis were given elaborately. The sample size seems sufficient. Results were summarized and presented using graphs and charts. Discussion of results was short and seems not adequate to address the objectives of the study. There was no attempt to explain the casual relationship. For example researches were making statements such as à ¢Ã¢â€š ¬Ã‚ ¦the introduction of water-impervious drapes and gowns did not seem to make a statistically significant improvement in the resultà ¢Ã¢â€š ¬Ã‚ ¦. (p.823). Researchers failed to acknowledge any limitations of the study. Data for this study was collected by reviewing patients records. Patients records are considers as confidential and researchers didnt mention whether they received consent from the patients or ethical approval form institution to conduct the study. This ca n be considered as an ethical flaw of this study. There are studies which found that laminar air-flow system is not effective in reducing infection rate. In their study Brandt C et.al (2008) found that infection rate was substantially high in theatres with laminar air-flow system. This was a retrospective cohort-study based on routine surveillance data from German national nosocomial infections surveillance system (KISS). Hospitals which had performed at least 100 operations between the years 2000 and 2004 were selected for this study. Type of ventilation technology installed in operation rooms of selected hospitals were collected separately through questionnaire from infection control teams in the participating hospitals. Surgical departments were grouped into categories according to the type of ventilation system installed. Departments using artificial operating room (OR) ventilation with either turbulent or laminar airflow was included in this study. Total 63 surgical departments from 55 hospitals were included in this study. Analysis was performed to the data set created by merging the questionnaire data on OR ventilation and surveillance data from the KISS data base. The data set analysed contained 99230 operations with 1901 SSIs. Age and gender of the patient was found a significant risk factor of SSI in most procedures. Univariate analysis conducted found that rate of SSIs was high in departments with laminar air flow ventilation. Multivariate analysis also confirmed this finding. Authors argue that it may be due to the improper positioning theatre personnel in horizontal laminar flow room. Researches provided a well-researched literature review which clearly identified gap in current research. Objectives and design of the study was properly explained. Study was based on a large sample size. Results were discussed in detail and casual relations were well explained. Enough tables were used to present results. Limitations were properly discussed. Knobben et.al (2006) conducted an experimental study to evaluate how systemic changes together with behavioural changes can decreases intra-operative contamination. This study was conducted in the university Medical Centre Groningen, The Netherlands. A random sample of 207 surgical procedures which involved total knee or hip prosthesis from July 2001 to January 2004 was selected for this study. Two sequential series of behavioural and systemic changes were introduced to ascertain their role in reducing intra-operative contamination. The control group consisted 70 cases. Behavioural changes (correct use of plenum) were introduced to the first intervention group of 67 operations. Intense behavioural and systemic changes were introduced to second intervention group of 70 operations. The systemic changes introduced was the installation of new laminar flow with improved airflow from 2700m3/h to 8100m3/h. Two samples each were taken from used instruments, unused instruments and removed bon es. Control swabs were also collected to make sure that contamination was not occurred during transport and culturing. Early and late intra-operative contamination was also checked. All patients were monitored for any wound discharge while in hospital and followed-up for 18 months to check whether intra-operative contamination affects post-operative infection. Among the control group contamination was found 32.9% while in intervention group 1 it was 34.3% and in intervention group 2 it was 8.6%. Except in Group 1 (p=0.022) late phase contamination was not significantly higher than early phase contamination. During the control period wound discharge was found in 22.9% patients and 11.4% of them had wound infection later. Deep periprosthetic infection had been found in 7.1% of them in the follow-up period. Deep periprosthetic infection was found in 4.5% cases of first intervention group and in 1.4% of cases in second intervention group in the follow-up period. But none of these decreases were found statistically significant. Contamination, prolonged wound discharge and superficial surgical site infection were found decreased after both first and second intervention. But a statistically significant reduction was found only in second intervention (contamination p=0.001, wound discharge p=0.002 and superficial SSI p=0.004). This study concluded that behaviour modifications together with improved air flow system can reduce intra-operative contamination substantially. Purpose of the study was clearly defined and a good review of the current literature has given. Gap in current research was clearly presented and justification for the study had given. Sample size seems sufficient. It is reported that à ¢Ã¢â€š ¬Ã‚ ¦.bacterial cultures were taken during 207 random operationsà ¢Ã¢â€š ¬Ã‚ ¦ (p. 176), but no details of the sampling method used were provided. Details of interventions were given elaborately and results were discussed in detail. But only one table and two charts used to present it. The readers would have been more benefited if more tables were used to present the results. Discussions of the results were concise and findings were specific and satisfying the objective. No information on whether they received informed consent from the patients and approval form the ethical committee of the institution was missing. This arise a serious question about the ethics of this study. It is found that laminar airflow is more effective when use in conjunction with occlusive clothing (Charnley, 1969 cited in Sandiford and Skinner 2009). While in their recent study Miner et.al (2007) compared the effectiveness of laminar airflow system and body exhaust suits found that body exhaust suits are more effective than laminar flow system in reducing infection. For their study Miner et.al (2007) selected 411 hospitals which have submitted the claim for total knee surgery (TKR) for the year 2000 from four US States were surveyed to collect the details of use of laminar air flow system and body exhaust suits. Those hospitals which were fulfilled three criteria were included in this study. The inclusion criteria were 1) returned the survey instrument, 2) using laminar air flow system or body exhaust suits for infection control and 3) was evidence of at least one Medicare claim for TKR for the study period. Total 8288 TKRs performed in 256 hospitals between 1st January and 30th August 2000 were selected. Data on patient outcomes after total knee replacement (TKR) were collected from Medicare claims. The patients who underwent bilateral TKR were not included in this study and for those who underwent a second TKR during a separate hospitalisation during the study period, only the first procedure was included. International Classification of Disea ses, Ninth Revision (ICDS-9) codes was used to identify post-operative deep infection that needed additional operation. Hospitals were grouped as users or non-users for both laminar airflow and body exhaust suits. Users were defined as those who use any of these methods in more than 75% procedures and non-users were those use any methods less than 75%. The over-all 90-day incidence of deep infection, subsequent operation was found required only in 28 cases (that is 0.34%). Analysis found that the risk ratio for laminar airflow system was higher (1.57, 95% confidence interval 0.75-3.31) than body exhaust suits (0.75, 95% confidence interval 0.34-1.62). Study found that there were no significant differences in infection between hospitals that use specific either protective measure. Other than mentioning few studies researchers failed to provide any background of the research problem. Methods used for this study were explained concisely. Even though the sample size was large, limited number of events (28) were there to be observed. Analysis was based on this small number of events; this may have affected the result. Not many variables were included in this study, and researchers didnt mention how they controlled some possible confounders. Researchers were successful in identifying the advantages and limitations of the study. Results were properly presented in tables. Instead of expensive laminar air-flow system, installation of well-designed ventilation system is found beneficial. Scaltriti et.al (2007) conducted a study in Italy to examine effectiveness of well-designed ventilation system on air quality in operation theatre. They selected operation theatres of a newly built 300 beds community hospital which have ventilation system designed to achieve 15 complete outdoor air changes per hour and are equipped with 0.3  µm, 99.97% HEPA filters. All these satisfy the condition for a clean room as per ISO 7 standard. Passive samples of microbiological air counts were collected using Tripticase Soy Agar 90 mm plates left open thorough out the duration of the procedure. Active samples were also collected using a single state slit-type impactor. Total 82 microbiological samples were collected of which 69 were passive plates and 13 were active. Air dust was counted with a light-scattering particle analyser. Details of the surgery, number of people in the room, door opening rate and estimated total use of the electrocautery unit were also collected. It was found that there were positive correlations between particle contamination, surgical technique (higher risk from general conventional surgery), electrocauterization and operation length. Door opening rate was found negatively associated. Researchers suggest that this may because when theatre door open a turbulent air flow blows out of the operating room which may result decrease in the dust particles. No association was found between particle contamination and number of people present at the time of incision. Researchers suggest that human movement rather than human presence is the factor that determines airborne microbial contamination. It was found that average particle concentration in the theatres did not exceed the European ISO 14 644 standard limits for ISO 7 clean room, and so concluded that well-designed ventilation system is effective in limiting particulate contamination. Uncultivable or unidentifiable organisms can also be a reason for surgical site infections. It may be difficult to identify such organisms through standard culture techniques (Tunney 1998). Clarke et.al (2004) conducted a quantitative study to examine the effectiveness of ultra-clean (vertical laminar flow) theatres in preventing infections by unidentifiable organisms. They used the molecular technique, Polymerase Chain Reaction (PCR), to detect bacteria presence. Their study compared the wound contamination during primary total hip replacement (THR) performed in standard and ultra clean operation theatres. 20 patients underwent primary THR from 1999 to 2001 were recruited for this study. Patients with previous incidents of joint surgery or infection were excluded. The standard operation theatres had 20 air changes per hour and CFU count was 50 CFU/m3, while ultra-modern theatres had 530 air changes per hour and CFU count was 3 CFU/m3. For all surgeries same infection control precautions were used. Two specimens each of pericapsular tissues were collected from posterior joint capsule both at the beginning and at the end of the surgery (total 80 samples). Patients were given antibiotic prophylaxis after taking the first specimen. All these samples were underwent Gram stain and culture to detect bacterial colonies and Polymerase Chain Reaction (PCR) to detect bacterial DNA. Among the 20 specimens taken form the standard operation theatres at the beginning of the surgery only 3 were found positive with PCR, while from the ultra-clean theatres only 2 were found positive. None from both theatres found positive with culture. Samples from the standard theatres taken at the end of the surgery, 2 found positive by culture and 9 found positive by PCR. The contamination rate in the standard theatre at the end of the surgery found significantly greater than the beginning (p=0.04). Samples taken from the ultra-clean theatres, none was positive by culture while only 6 were positive by PCR. Statistical analysis found that contamination rate at the end of the surgery is not statistically different than the start (p=0.1). It was found that there were no statistically significant difference in overall contamination rate (p=0.3) between standard and ultra clean theatres. (I will add critique of this study here) NURSES ROLE IN INFECTION CONTROL Understanding the source of contamination in operating theatre and knowing the relationship between bacterial virulence, patient immune status and wound environment will help in improving the infection rates (Byrne et al 2007). Nurses are responsible to take a proactive role in ensuring safety of their patients. To improve patient outcome, it is necessary for the nurses to take lead role in environmental control and identifying hazards through environmental surveillance (Neil 2005). Non-adherence to the principle of asepsis by surgical team is identified as a significant risk factor of infections. Hectic movement of surgical team members in the operating room and presence of one or more visitors were also found as major causes of SSI (Beldi G 2009). Nurses and managers should emphasise on controlling factors like the traffic in theatre, limiting the number of staff and reinforcement of strict aseptic technique (Allen 2010). Creedon (2005) argues that infections can reduce up to one third if staffs follow best practice principles. For better outcome staffs needs additional education and positive reinforcement. Nurses have a vital role in the development, reviewing and approving of patient care policies regarding infection control. Nurses are not only responsible for practicing the aseptic techniques but also responsible for monitoring other staff for their adherence to policies. They are responsible for developing training programmes for members of staff. Educating the environmental services personnel like technicians, cleaners will not only improve their knowledge in patient care but also provide a sense of commitment in patient outcomes (Neil 2005). Perioperative nurses can contribute in research regarding theatre ventilation system through organised data collection and documenting evidences. Nurses can contribute in giving optimum and safe delivery of care in areas where environmental issues can put the patient at risk. Knowledge is changing fast, so it is important that staff must keep themselves up to date. Continues quality improvement is needed and it should be based on evidence based research and on-going assessment of information (Hughes 2009). CONCLUSION Reviews of current research shows that still there is a lack consensus on the effectiveness of laminar airflow in infection control. Studies include in this review has used either clinical outcomes (infection or reoperation rate) or intermediate outcomes (particle count or bacterial count) to evaluate the effectiveness of laminar flow. Kakwani et.al (2007) found that re-operation rate was lower in laminar airflow theatres but Brandt et.al (2008) found SSI rate was high in hospitals with laminar flow. Clarke et.al (2004) found that contamination was not significantly different in ultra clean theatres compared to standard theatres equipped enhanced ventilation system. Supporting this finding Scaltriti et.al (2007) found well designed ventilation system is effective in reducing contamination. Study by Knobben et.al (2006) found that combination of systemic and behavioural changes are required to prevent intra-operative contamination. Miner et.al (2007) found that there were no significant differences in infection between hospitals that use laminar airflow and body exhaust suits. From these studies it can be concluded that use of laminar airflow alone can guarantee infection prevention. Behavioural and other systemic changes are necessary to enhance the benefits of laminar airflow. Evidence shows that conventional theatres equipped with enhanced ventilation system can prevent infection effectively, this can be consider as an alternative for expensive as laminar flow system.

Margins: Meaning of Life and Frazier Essay

In Ian Frazier’s essay, â€Å"In Praise of Margins†, the author talks about his childhood life and how he had â€Å"margins† where he and his friends would do things and nothing would matter because they wouldn’t care. â€Å"Marginal† thought is valuable because it allows adults to use their imagination. His purpose is to try new activities without shame; it’s the spur of the moment that defines margin. I think his view about marginal activity is comprehensive and relatable. When we think of margins, we think of the extra space on the edge of the paper that we can’t write out of. But marginal has another meaning to it which has to do with the economic world and how we function with margins in our life such as personal experiences. Marginal space is key to the coming of age process in each person’s life whether we share the same activities or not. Although it’s not easy to pin point it out but marginal spaces are needed to escape from everyone’s present problem in everyday life. I agree and believe with Frazier when he is talking about the meaning of marginal because it is true that margins sometimes do not come out the way you want it to be, nothing or nobody is perfect and there are always something ruining the perfect moment that we all have or want. Marginal act take such a high valued meaning according to Frazier because the places and activities that he discovered through his childhood is something that has been lost in the past and also in many societies, especially the economic society. According to Frazier, he added, â€Å"†¦the margin is where you can try out ideas that you might be afraid to admit to with people looking on. † (7) This is an important concept to anyone’s life. One person’s marginal space can different from another person’s as long as it is an activity in which the person escapes from reality. In an economic society, time is considered money and Frazier’s activity of sitting on a tree for hours is more on the lines of suicidal, in economic society’s terms. Frazier agreed that he felt useless at the time of just sitting but as he grew older, the useless time of gazing off turned into something sacred towards him. The sitting in the tree gave him memories and something to reflect back on. It came upon me when I took my nephews out to the ice rink at the Christmas in the Park; I realized if I never done this I would have missed out on what defined me as of today. Though it’s all fun and games I know that it’s one of the activities you can do once in a while that can take you away from your stress and busy day life-style. Reflection cannot happen when there is nothing to look back on. There are always memories that others have whether it be good or bad. It might be their first time driving or their first time swimming. Any memory is something someone can reflect back onto to see who they are and to see how they got to the place they are now. The economic society always keeps moving on and thinks about the future, while human beings need time to focus and reminisce from where they came from. If someone keeps running straight with their heads down, they might get far but eventually, they will get lost. In order to stay on track and know where you’re heading, at times the person needs to look back to see where they started from. Know where you are is the most important thing to knowing who you are and Frazier realized the great importance of that. Frazier’s useless â€Å"marginal† activity such as just plainly sitting brought out the importance of just doing things not to gain a profit but to gain something to reflect on. When Frazier was younger, he had his own marginal place and would always go out to â€Å"the woods†; it was his â€Å"part-time address, destination, purpose, and excuse† (1). While Frazier ran around bumping into bushes and branches, slipping and sliding through thick brown dirt; I was ice skating at the ice arena, hop-scotching, and playing house. Throughout my childhood, I dedicated numerous hours in the freezing cold ice arena at the local mall, hop-scotched afterschool with my neighbors, and played house on the weekends with my cousins. These activities may sound typical as a child but it had a significant meaning towards me. It was my purpose to grow upon these marginal experiences. In the end, all that matters is being able to free your mind from something that you free yourself from caring about what others think. And I believe that I accomplish my marginal activity as a child, through every fall and bruises that I received while ice skating, I couldn’t care less about what others had to say about me because I knew that every time I got up it’ll only make me a better skater in the end. Although changes occurred and I grew out of the marginal acts, agreeing with Frazier’s realization, â€Å"†¦and suddenly there was nothing up there for us. † (4) The excitement of skating on the slipping cold ice with no shame of failing can only be done as a marginal act, because I can no longer look at the rink the same way I did when I was younger. Nor can I play hop-scotch the way I did, hopping from one box to another is like going from one class to another today. Instead of playing house with my cousins, we became college students looking for a stable job that can support our education. I agree with Frazier that the â€Å"remember whens† really does faltered and â€Å"playing† time doesn’t have to end here. Although margins can be done differently and looked at differently, marginal is necessary for a person of all ages to let loose in order to overcome the pressure and stresses of everyday life. Frazier’s marginal activities consisted of breaking ice, climbing trees, and picking fruits. My marginal activities consisted of ice skating, hop-scotching, and playing house. Marginal activities may vary from being active in a sport, traveling, singing or perhaps even enjoying a movie night on the couch; by the end of the day marginal activities is necessary in order to free yourself from the strains of everyday life.
