Well Done Personal Essay - Sample Essay

Three times a week after school I go visit my dad. When I enter the hospital room where he has lain in a coma since his accident, my eyes often wander to the lone golf ball my mom placed at his bedside. Just six months ago, my father was driving a golf cart across the street that bisects the local golf course when he was hit by a car. He suffered severe brain injury, and the doctors have ruled out any possibility of him waking up again. When I look at him lying in bed, frail but peaceful as if he were asleep, its hard not to dwell on the what ifs: what if he hadnt played golf that day? What if he hadnt been behind the fence when the black Camry plowed into it? What if I still had the chance to ask all those questions that choke me up when I see him in the hospital? I cant pretend that I have developed enough distance from the event to draw conclusions about life, but I am already beginning to see myself in very different terms.Ironically, through this accident my dad has given a chan ce to face reality head-on. Before the accident, my relationship with him was warm but fraught with tension. He never seemed satisfied with what I did and reprimanded me for every wrong step I took. He had strong opinions about my hairstyle, clothes, friends, and—above everything else—my academic performance. When I was not sitting at my desk in my room, he invariably asked me why I had nothing to do and told me I should not procrastinate. He stressed that if I missed my teenage years of studying, I would regret it later. He didnt like me going out with my friends, so I often ended up staying at home—I was never allowed to sleep over at other students homes. All I remember from my past high school years is going to school and coming back home. I was confused by my parents overprotective attitude, because they emphasized independence yet never actually gave me a chance to be independent.In terms of career, my dad often lectured me about which ones are acceptable and which are not. He worried incessantly about whether I would ever get into college, and he often made me feel as if he would never accept my choices. Rather than standing up for myself, I simply assumed that if I studied hard, he would no longer be disappointed in me. Although I tried hard, I never seemed to get it quite right; he always found fault with something. As if that werent enough, he frequently compared me to my over-achieving older brother, asking me why I couldnt be more like him. I must admit that at times I even questioned whether my dad really loved me. After all, he never expressed admiration for what I did, and my attempts to impress him were always in vain.In retrospect, I dont think I fully understood what he was trying to tell me. These days, when I come home to an empty house, it strikes me just how dependent on my parents care and support I have been so far. Now that my dad is in the hospital and my mom is always working, I see that I must develop the streng th to stand alone one day. And, for the very first time, I now realize that this is exactly what my dad was trying to make me see. I understand that he had a big heart, even though he didnt always let it show; he was trying to steer me in the right direction, emphasizing the need to develop independence and personal strength. He was trying to help me see the world with my own eyes, to make my own judgments and decide for myself what I would eventually become. When my dad was still with us, I took all of his advice the wrong way. I should not have worried so much about living up to my parents expectations; their only expectation of me, after all, is that I be myself.In mapping out my path to achieving my independence, I know that education will allow me to build on the foundations with which my parents have provided me. My academic interests are still quite broad, but whereas I was once frustrated by my lack of direction, I am now excited at the prospect of exploring several fields b efore focusing on a particular area. Strangely, dealing with my fathers accident has made me believe that I can tackle just about any challenge. Most importantly, I am more enthusiastic about my education than ever before. In embarking on my college career, I will be carrying with me my fathers last gift and greatest legacy: a new desire to live in the present and the confidence to handle whatever the future might bring.CommentsThis essay does a good job of evincing the applicants concern for others, confidence, insight, maturity, optimism, and success in working to overcome a very difficult situation. The students language brings across genuine emotion without falling prey to melodrama. The introduction, though somewhat sorrowful, ends with a focused statement on how the accident has propelled the student to reassess himself, his relationship with his father, and his life in general.The essay does an excellent job of building upon previous points and moving the reader toward the co nclusion. The flow and coherence do not waver, keeping the readers attention focused. The student is able to display how he has changed from a naà ¯ve, confused child into a mature, understanding young man (I was confused by my parents overprotective attitude†¦I must admit that at times I even questioned whether my dad really loved me†¦I see that I must develop the strength to stand alone one day.).The conclusion ties the material back to education without making the reader feel sorry for the writer. The student is strong, not dwelling upon the unfortunate nature of his circumstances, but rather focusing upon how he is using and will use his fathers condition as a motivating force in his life. The piece ends on an uplifting note, showing the students strong character and maturity.

10 Signs You Shouldnt Take the Job

10 Signs You Shouldnt Take the Job You’ve been searching and searching and finally you find yourself with a job offer in hand. Trouble is, there are a few red flags. How do you know when you should really turn a job down instead of taking it? Remember: you’ll spend a significant chunk of your adult life at work. You might as well not be miserable. Here are ten ways to tell if you should pass and hold out for something better:1. Unprofessional/Untimely CommunicationIf your perfectly reasonable emails with questions go consistently unanswered. If you receive communications that are not clear, thorough, or respectful. If appointments or interviews are cancelled at the last minute without explanation or apology. If your questions are dodged or not answered to your satisfaction†¦ None of this bodes well. If a company can’t get it together in the hiring process, chances are the job itself will be even more frustrating.2. Ghost companyYou’ve Googled and Googled and you still can’t find any substantive information about the company. Or worse- what information you can’t find is bad or negative press. Or bad Yelp reviews! Or worst- bad reviews from former employees. One or two outliers shouldn’t be a big deal; but consistently negative information? Run.3. Aggressive InterviewerIf your interviewer starts giving you the hard sell and trying to convince you to take the job on the spot, that’s not a great sign. It smacks of desperation. Similarly if a recruiter tries to push you in the direction of a particular job. No job is immediately perfect without going through the proper process. And you can always take time to think it over and say no.4. TurnoverYou’re looking at an old company, but none of the employees have been there for more than a year. Ask yourself why the company has such a hard time keeping good people on long term? This is especially true if your interviewer starts badmouthing her current team.5. Repeat AdsYou keep seeing the same job posting popping up on job sites. Over and over again. This is never a good sign.6. Asks for moneyAs outlandish as this sounds, it does happen, and you should be wary of it. If anyone asks for money for background checks or training, just cut and run.7. Defeated workersIs the climate in the office chilly, doomy, or gloomy? Do all the employees look hunched over and defeated? Read their body language and the energy in the room. Does it look like they want to be there?8. No path forwardThere’s no mention of how you might grow into and beyond your position. Don’t let yourself get stuck in a dead end job. Similarly, if there’s no clear description of the job’s duties or your role. If they can’t tell you what success would look like in your position, it will be impossible for you to succeed in such a place.9. Bad bossHonor that feeling in your gut that says you just don’t like your potential supervisor. Either they don’t seem to t rust you or you get a bad vibe from them. Trust this instinct and save yourself months or years of unhappiness.10. Instant hireBe wary of any company that wants to hire you on the spot without calling any of your references or doing a background check. It could just be a super casual company policy, or it could speak of desperation on the employer’s part. Which, again, is never a good sign.

For "one person, one cup and a neighborhood at a time," Starbucks has its own way of developing loyal customers and contributes to the environment even as it makes its profits (Diane, Raven, & Al-Mutair, 1998). In another article on "Wake up and smell the coffee," by Anonymous author, it is stated that during when Starbucks is roasting its coffee, there is a production of smoke that when released to the environment just that way, it causes environmental pollution (Anonymous, 2006). This would show how Starbucks engages in an activity that is considered unethical or illegal. However, the company tries so much to reduce this issue by completing the oxidation process of the material into CO2 and water, which are, therefore, safe to release to the

Construction and Maintenance of Building Essay Example | Topics and Well Written Essays - 1500 words

Construction and Maintenance of Building - Essay Example In addition, the primary source of energy for the building will be generated from a Combined Heat and Power (CHP) unit. Combined power and heat integrates the production of usable heat and power (electricity), in one single, cost effective and highly efficient process. The CHP system is sustainable, clean and renewable. CHP generates electricity while also capturing usable heat that is produced in this process its efficiency is greatly increased. This is unusual contrasts with conventional ways of generating electricity where heat is simply wasted and in the process impacting negatively on efficiency. In today’s coal and gas-fired power stations, up to two-thirds of the entire energy consumed get lost in such a way, frequently witnessed as a cloud of smoke rising from the cooling turrets, the process is very environmentally unfriendly. This will be a very eco-friendly aspect of construction as it is very efficient in its purpose and design. Sub-structure or Foundation- is the lower section of the building, located below the ground level and the damp proof course. A foundation is part of the structure that is in direct contact with the ground to which the loads are equally transmitted to the supporting surrounding soil. Shrinkable soils are those types whose contents are made up of more than 35% have a modified plasticity index greater or equal to 10% and of fine particles. The fine soil particles are having nominal diameters of 60 Â µm. Plastic index of a given soil is its measure of the change in volume potential that is determined by Atterberg Limits test. Soil particles whose nominal diameters after the test are greater than 425 Â µm are eliminated through sieving in advance. Particles with diameters smaller than 425 Â µm are promptly reported for Atterberg Limits test. The Plasticity index of the soil multiplied by the real percentage of particles with contents less than 425

Lifelong Learning Essay Example | Topics and Well Written Essays - 4500 words

Lifelong Learning - Essay Example H G Wells was correct when he said that 'the whole of human history is a battle between education and catastrophe' (cited in Fischer, 2000, p. 265). Those of us immersed in a lifelong learning culture can all sense that the new millennium brings with it the opportunity for a new beginning. But we can all see, as well, the scale of the task ahead just to make it happen, perhaps starting in our own communities and branching out from there with new understandings, new persuasions, new insights, new wisdom. Thanks to inter-governmental organizations-UNESCO, OECD, APEC, the Council of Europe, The European Commission and others - and some of the more enlightened liberal democracies, the lifelong learning movement is now rampaging around the whole world, from Europe to South Africa and from North America to Japan, like a benign educational plague. It is the future-and it is not before time. In Lifelong Learning, written 12 years ago, Longworth and Davies suggested eight reasons why lifelong learning is particularly appropriate for this age. But nine years is a long time in a lifelong learning world. While some are still as relevant as on the day they were written, it is time to update the rest to take into account the changes in the meanwhile: Fundamental global demographics-in the rich developed world, ageing, more mobile, more multicultural and multi-ethnic societies which could release high inter-racial and inter-generational social tensions and a reduced investment in welfare programmes through a fall in working, and an increase in retired, populations. By contrast, in the poorer parts of the world a massive population growth exacerbating already chronic shortages of resource and education and condemning vast numbers of people to live at subsistence level and below... The pervasive influence of television and the media on the development of peoples' thoughts, ideas and perceptions. Television has an enormously powerful effect on people. Where it is in the hands of those who would use it as an instrument of propaganda, whether raw or subtle, as happens in both poor and rich countries, it can be used to foster hatred and intolerance. Where it is used purely as an instrument of entertainment, it can, through trivialization and ignorance of real issues, have an equally insidious effect on the ability of people to make informed choices. As an occasional, independent, instrument of education it could be used to transform nations into dynamic, well-educated and flexible lifelong learning societies (Marsick, 1998, p. 119). Environmental imperatives - the depletion of the world's resources and the need for renewable energy, the destruction of ecosystems and the demand for sustainable development. There is a crucial need to educate continually all the world's people in environmental matters as a basis for the survival of species on earth and to be inventive and innovative about how environmental information is kept constantly in the forefront of popular consciousness. In other words, the need for a lifelong learning approach to a lifelong survival issue (Swedburg & Ostiguy 1998, p. 27). These are issues affecting every society and they propagate a view of lifelong learning as a global phenomenon, entirely consonant with the reality of governmental perceptions.

Sequencing Technology for Epilepsy Diagnosis

Sequencing Technology for Epilepsy Diagnosis Epilepsy: It is estimated that at many as 10% of the general populace will experience a seizure in their lifetime. (Persad et al., 2003) Epilepsy is a chronic neurological disease defined by its characteristic symptom, recurrent and spontaneous seizures. (Berg et al., 2011) (Asher Y et al., 2012) Epilepsy is a common condition with an occurrence of up to 3% in the population (Deng H et al., 2013). According to Pal D.k et al., (2010) over half of epilepsies have a genetic cause. A large body of research has gone into identifying the genetic causes and corresponding molecular mechanisms of epileptic disorders. Epilepsies have a wide variety of causes including dysfunctional ion channels (channelopathies), abnormal brain development and errors of metabolism etc. (Garofalo S et al., 2012) Research in the genetic mutations behind epilepsies is vital in further understanding the pathology of the many different conditions and developing superior treatments for the afflicted patients. Early Onset Epileptic Encephalopathy: Epileptic Encephalopathies are a large number of rare (prevalence of 1et al., 2010). The symptoms of an EE generally include severe and recurring seizures along with cognitive and developmental delay and/or deterioration. This cognitive and behavioural decline may be influenced by the seizure activity as well as the underlying mechanisms of disease (Kaiman B.A. et al., 2012). The term Epileptic Encephalopathy encompasses a wide variety of syndromes with a diverse range of genetic causes and considerable overlap with other syndromic disorders such as Autism and Mental Retardation. (Berg et al., 2011). The overlap in these syndromes and continuing progression in our understanding of EE’s has resulted in A.T. et al (2010) emphasising that the term epileptic encephalopathy should be viewed as a â€Å"concept and a description† of the wide spectrum of epileptic conditions with an encephalopathic course that are being observed in the clinic. A key diagnostic feature is that Epileptic Encephalopathies tend to occur in infancy to early childhood. While adults can suffer from epilepsy with encephalopathic features this does not tend to be as severe as the Early Onest Epileptic Encephalopathies (EOEE). Children suffering from EOEE’s rarely make it to adulthood due to their poor prognosis. Berg A.T. et al (2010). While more research is coming to light on the potential lasting damaging effects of seizures (Berg et al., 2011) what is certain is that the early onset and repetition of the severe seizures present in EOEE’s is devastating to the early development of patients and their continued growth. As the patients progress from a neonate towards childhood their symptoms will also progress. For example seizures in neonates may not be observable to a clinician as the axonal pathways are not fully myelinated yet and prevent the â€Å"surge† from reaching the motor cortex. Once the brain is fully myelinated the seizures would become observable clinically even though the onset was much earlier in the neonatal stage. This progression of the clinical presentation of epileptic seizures is mirrored in the likelihood of infants suffering from Early Infantile Epileptic Encephalopathy (Otohara syndrome) to develop into Infantile Spasms (IS) at 3-6 months in life. Patients’ suffering from IS tend to develop into Lennox-Gastaut syndrome in childhood. (Asher Y et al., 2012) Diagnosis and treatment: As seen in table 1 and table 2 there are a number of epileptic encephalopathies with a clear enough presentation to make an accurate diagnosis based on the clinical symptoms alone. However due to the rarity of these conditions and the occurrence of EOEE’s with unclear presentations (I need a %?) confirmation of a candidate mutation (gene?) is considered the gold standard when it comes to EOEE diagnosis. (Lemke J.R. et al., 2012) In Lemke J.R. (2012) it was shown that when comparing the diagnostic results of a target gene panel against a clinician’s suggested diagnosis that the gene panel results matched the suggest diagnosis in the EOEE’s with clear presentations. This accounted for 50% of the cohort. However for the remainder of the cohort with unclear EE symptoms there very few suggested diagnoses and not all of these were accurate. It has been suggested by Kay C, (2012) that the significant failure to confirm a genetic diagnosis for unclear EE’s is due to the role of de novo variants as candidates. While we may have the above lists of confirmed disease and causative gene mutations in tables 1 and 2 there are still many other EOEE’s without validated genetic causes that could be the result of de novo mutations in the patients. Considering the ever increasing list of epilepsy linked (but not validated) genes, 265 of which identified in (Lemke J.R. et al., 2012)) it is clear that the current gold standard of diagnosing EOEE’s isn’t high enough. A case study shown by Zupanc M.L., (2009) recorded the diagnostic process of a patient â€Å"Kay† that originally presented with slight head drops at 7 months old. Correlating the head drops to an epileptiform EEG (in this case a â€Å"generalised high-amplitude burst of polyspike, spike and slow wave discharges†) allowed certain conditions to be ruled out however it was highlighted that while a confident diagnosis was reached there were alternatives that cou ldn’t be ruled out. Difficulty in EOEE diagnosis can stem from the multitude of potential genetic causes available for some presentations which can lead to a clinician wandering blindly picking candidates for Sanger sequencing to identify a candidate mutation. (Lemke J.R. et al., 2012) Next generation sequencing technology: If the issue in diagnosing EOEE’s is the lack of validated genetic causes for the different presentations then the most comprehensive way to investigate the matter is to examine the EOEE genomes in comparison to controls and identify the candidate genes. Next generation sequencing technology has provided the means to do this and recent years have seen a surge of NGS based studies in EOEEs and their genetic causes. (Lemke et al., 2012) (Veeramah K.R. et al., 2012) (Veeramah K.R. et al,. 2013) The original human genome project was officially announced as completed in April 2003 (Wheeler D.A., et al. 2013). This project made use of the hierarchal shotgun sequencing method (Chial H et al., 2008). This entailed the use of bacterial artificial chromosome clones (BAC) which each housed a 100Kb fragment of DNA. Over 20,000 over these BAC clones were mapped to the human genome and the order in which these BAC clones would be aligned was the tiling path that would be followed to sequence each human chromosome. The BAC clones are further sub divided into 2 Kb fragments (appropriately sized for sequencing) and these are sub-cloned into plasmid vectors and the fragments that will undergo sequencing. The sequencing was undergone by capillary electrophoresis methods. As long as there is sufficient overlap between these sequences they can be aligned to recreate the BAC clone structure. Then using the BAC clone mapped tiling path the sequences of the BAC clones can be aligned to create a contiguous stretch of sequence that represents the human chromosome. (Mardis E.R., 2008) The advances made in this area to create the next generation sequencing technologies involve a movement away from capillary electrophoresis methods and changes in the methods of how the DNA fragments are assembled to produces the genome sequence. Whole Genome Sequencing removes the use of BAC clones and instead the genome is fragmented into different distinct size classes and placed into plasmid and fosmid subclones. By generating paired end reads and using the number of bases between these reads based on the size classes the genomes can be sequenced quicker than using BAC clones. Next generation sequencing platforms allow for massively parallel DNA sequencing and come in a variety of different set ups. As the need for BAC clones has been removed the sample preparation process is much quicker and cheaper than the method used in the original human genome project. Also while the actual run time of the next generation sequencers is longer than that of the capillary based platform the fi nal yield of reads is much higher (from 96 reads on the capillary platform to up to tens of millions on a massively parallel system). This explosion in genomic sequencing technology less than two years after the completion of the first human genome project has provided an astonishing change in the pace of genomic research. (Mardis E.R., 2008) NGS read diagrams? Next generation sequencing and epilepsy: The study of genetic diseases including the EOEE has benefitted greatly from the genome sequencing revolution. Whole genome sequencing techniques have been used to identify a de novo variant in the SCN8A gene which encodes voltage gated sodium channel pore-forming alpha-subunits. Following discovery of the variant the effects of the variant on channel function was observed and shown to implicate the gene’s involvement in EOEE and Sudden Unexpected Death in Epilepsy (SUDEP). (Veeramah K.R., et al., 2012). Targeted gene panels (next generation sequencing of a list of target genes coding regions only) has proven effective in diagnosing clear presenting EOEE and even providing a potential causative variant when no clinical diagnosis is possible. Most impressive of all was the use of whole exome sequencing (WES) to identify de novo candidate variants of relevance in 7 out of 10 children and potentially identifying 3 new genes that could be linked to EOEE (Veeramah K.R. et al., 2013 ) WES is the process of sequencing only the human exome rather than the whole genome. The exome consists of all the coding regions (exons) of the genome. Even though the exome only accounts for 1% of the whole genome it is estimated to contain 85% of disease causing mutations (Choi M et al., 2009). As of April 2013 U.S. National Human Genome Research Institute claims to sequence a whole genome at the price of $5826. The Howard Hughes Medical Institute claims to sequence the whole exome at the all-inclusive cost of $500. The Broad Institute of Massachusetts Institute of Technology estimates that whole exomes can be sequenced at four times the rate of the genome in their facility (Perkel J.M 2013). This rapid and ongoing reduction in cost is mirrored at the rate WES projects are being undertaken. With a date filter for the end of 2010 on Pubmed I performed the search â€Å"exome sequencing† and found a total of 44 articles. By the end of 2012 this 805 and by the end of 2013 the nu mber had more than doubled to 1,751. Whole exome sequencing projects have the advantage of not only being cheaper and faster than whole genome projects but also are a more comprehensive option than targeted gene panels for identifying EOEE candidate variants. While not as complete in whole genome sequencing in scope 85% covers a significant amount of data to be analysed and only leaves a 15% chance of not finding a candidate variant. It should also be noted that the exome is much easier to process and analyse while the whole genome includes non-coding areas which we are currently not really able to analyse in such a way to validate the relevant link between disease and non-coding variants (Perkel J.M 2013). Hypothesis: The question we are trying to answer with these projects is â€Å"Can whole exome sequencing detect candidate disease causing variations in early onset epileptic encephalopathy patients†? As this project involves isolated probands and one family trio it also raises the question of whether the inclusion of parent WES data allows for more rapid and accurate variant analysis. As such the end research goals are to identify likely and relevant disease candidate variations in the proband WES data and confirm their presence with Sanger sequencing The benefits of WES studies in EOEE candidate variants are numerous and important. Identifying a confirmed candidate mutation can allow an affect family to receive genetic counselling. If a clear mechanism of disease can be ascertained from the disease candidate then potentially alternative anti-epileptic therapy can be implemented based on the specific condition to improve patient prognosis even slightly. Along with this as EOEE have such a wide variety in causes and mechanisms some can respond poorly to some standard anti-epileptic drugs and lead to rapid deterioration of the patient. Identifying a genetic cause can prevent this from happening. (FIND REFERENCE) On a larger scale understanding the complex mechanisms of these devastating disorders is the only way to improve and develop treatments for these conditions and improve patient prognosis. Understanding how these rare forms of epilepsy manifest may in turn provide clues into the mechanisms of the more common forms of epilepsy . (FIND REFERENCE) As more research is beginning to highlight the role of earlier onset of seizures on the developing brain and the encephalopathic effects WES could become an effective screening tool in the future that would allow early intervention to control or prevent these devastating seizures and greatly improve patient standard of life and change EOEE to a more manageable condition.

State of Research on the Snowball Earth Hypothesis Essay -- essays res

State of Research on the "Snowball Earth Hypothesis" The "Snowball Earth Hypothesis" also known as the "Varangia glaciation" is a hypothesis presented in 2001 by Geologist Paul Hoffman. (Wikipedia, 2002) The hypothesis purposes that 540 million years ago during the Neoproterozic, a meter thick of ice covered the oceans and glaciers the continents for 100 million years. Albedo; when ice and snow reflect solar radiation into space, in absents of greenhouse gases, which don't exist within the atmosphere, heat therefore escapes the planet. A condition of temperature disequilibrium occurs, when freezing cold reaches a state, the climate never warms to normal, and cold freezes the hemisphere and buries it under massive glaciation. The glaciers begin when a green house gas, carbon dioxide, is depleted from erosion of silicates. Once the atmosphere is depleted of carbon dioxide, it can not absorb solar radiation. The global tempertures drops to cold and glaciation occurs, glaciation continues, temperature gradients drop further to colder, below freezing, cold is irreversible, glaciers reflect solar radiation into space. The lack of atmospheric carbon dioxide prevented greenhouse from occurring, earth is frozen until the hemisphere is totally glaciated. (Hoffman, 1998) Deglaciation can occur when volcanic eruptions saturate the atmosphere with carbon dioxide gas and resume the greenhouse effect on climate. Solar radiation is absorbed by greenhouse gases, rewarming the climate. A dramatic expansion of the biosphere occurred. ("Cold") History of "Snowball Earth Hypothesis" A tree toppled during a hurricane. A 700 million year old rock bed was discovered in Appalachia. The rock, diamictite consisted of basalt -size cobbles mixed with a slurry of fine silt and sand. The region consisting of Appalachian Blue Ridge range, Sharp Top mountain had once bordered a seaway cutting through Rhodina, a giant continent that included most of the worlds land. Sharp Top contained signs of tides, indicating the glacier had streached down to the sea. During this time, Virginia was 15' to 30' of the equator.

Pepe Jeans Case Essay

The main advantage of Pepe not carrying inventory is obviously the cost savings, as it is usually not efficient or cost effective for that matter, to carry excess inventory. The downside is not having enough pairs of jeans on hand to ship to stores when demand is high. An inventory would help alleviate this. The six month lead time is both an advantage and disadvantage for Pepe. The long lead time is positive in that once a retailer places an order, they only have a week to cancel the order. Pepe is able to realize a profit after only ten days rather than months later. The contract locked retailers in immediately and keeps them from reneging on the deal. The downside is that many stores may be turned off by the long lead. It was mentioned in the article that most manufacturers have lead times of a few months or less. The independent stores also tended to order less volume due to the inflexible order system, and the trouble with fashion is that items typically have a short wearable life before they go out of style. Corporate purchasers were worried that the jeans they ordered may go out of style before they even arrive. If I were the manager of Pepe, I would assure my retail partners that every reasonable action was currently being taken to help reduce the current lead time. I would mention the options being considered and thank them for their partnership. I would then sit down with the CFO as well as the best analysts in the company and run reports to forecast the most efficient method of reducing lead time. The case mentions two alternatives to reduce lead time: working with a Hong Kong sourcing agent or building a finishing operation in the UK. Without seeing the company’s financials, it is difficult to say which would be a better choice. The article does mention that Pepe has no long term debt and appears to have plenty of cash on hand. If that is truly the case, then the better option may be to invest in the finishing factory. There would be a large investment up front, but lead time could be cut in half while reducing costs by up to ten percent as well. On the other hand, the sourcing agent could possibly reduce lead time down to as little as six weeks. The problem with this option is that costs to soar by as much as thirty percent.

Biography on Julius Caesar Essay

Biography on Julius Caesar Essay Biography on Julius Caesar Essay Julius Caesar Julius Caesar was born in July 100 BC and died in March 44 BC. He was known for being a politician and general of the late Roman republic, who greatly extended the Roman empire before seizing power and making himself dictator of Rome, he was a statesman, Consul and author. He is deemed one of the greatest military commanders in the history of the world. At the age of seventeen Caesar married Cornelia, the daughter of a powerful politician in Rome. He joined the Roman Army in 81 BC and became the first Roman General to invade Britain when he built the bridge across Rhine.Caesar also became the first living man to appear on a Roman coin. Even the month of the year that he was born, Quintilis, was renamed July in his honour. Caesar was made a consul in 59 BC and in 58 BC he went to Gaul (France) where he served as governor. He was prosperous in this position and conquered more land for the Roman Empire. Caesar's soldiers were extremely loyal to him at a military level yet by some he was seen as a man only working to expand his power, this made him unpopular among many important politicians in Rome. Some senior army generals, such as Pompey, were questioning Caesar's intentions. At the end of his term as consul, Caesar became commander of the Roman Army. Caesar was confident that in the long term, his well-organised forces would be able to defeat the Gauls that controlled central and northern Europe. First he defeated the Helvetii, he followed this with victories over the Gauls that lived in northern Europe and after reaching the English Channel in 55 BC Caesar decided to invade Britain. To make sure everybody knew about his military victories, Caesar wrote a book about his campaigns and had it published in Rome. The Senate became concerned about his growing popularity and after his military victories they appointed another famous Roman soldier Pompey, to take control of the country, to prevent Caesar from gaining power and passed a motion insisting that Caesar should retire from office. In 49 BC, after his invasions, Caesar returned to Italy, the Senate ordered Caesar to hand over his army to their control, due the the Republic's laws. Disregarding the authority Caesar famously crossed the Rubicon River and advanced to confront his enemies in Rome. In the consequential civil war Caesar defeated the republican forces. Pompey, their leader, fled to Egypt where he was assassinated and for the next 3 years Caesar picked off his enemies one by one whether they were in North Africa, the Middle East or Europe. Caesar followed Pompey into Egypt and became romantically involved with the Egyptian queen, Cleopatra, who was 21 and he 52, he had been married three times before.Caesar and Cleopatra seemed to have become lovers shortly after meeting and Caesar remained in Egypt with her nine months.On 23 June 47 BC

Critically evaluate the extent to which international law recognizes a Essay

Critically evaluate the extent to which international law recognizes a right of self-defence to prevent attacks by terrorist organizations - Essay Example This paper aims to provide an articulate understanding of the author’s point of view in conclusion to this discussion, after critically evaluating the various provisions contained in the UN Charter regarding the right of a State to defend itself. â€Å"Nothing in the present Charter shall impair the inherent right of individual or collective self-defence if an armed attack occurs against a Member of the United Nations, until the Security Council has taken measures necessary to maintain international peace and security. Measures taken by Members in the exercise of this right of self-defence shall be immediately reported to the Security Council and shall not in any way affect the authority and responsibility of the Security Council under the present Charter to take at any time such action as it deems necessary in order to maintain or restore international peace and security.†1 Under this provision, there is an inherent right of individual or collective self-defense of any member of the United Nations in case there is an armed attack that occurs.2 However, there is a limitation provided, in that, it is subject to review by the Security Council.3 Under customary international law, the pre-requisites to legitimate self-defense include the following: â€Å"1) an infringement or threatened infringement of the territorial integrity or political independence of the defending state; 2) the failure or inability of the other state to prevent the infringement; 3) the absence of alternative means to secure protection; and 4) the strict limitation of the defending states use of force to prevent the danger.†4 Although Article 51 of the UN Charter considers self-defense as an inherent right under customary international law, the provision providing for an â€Å"armed attack† is much debated.5 Various interpretations have also been made as regards the word â€Å"inherent† in the exercise of self-defence.

Human Ecology Essay Example | Topics and Well Written Essays - 250 words

Human Ecology - Essay Example According to various studies undertaken regarding food consumption within the U.S, approximately a third of the total calories are obtained through junk foods (Adams, 2004). This can be associated with the elevated cases of obesity among the U.S populace. Conversely, LDC for instance Haiti depend on indigenous diets that often offer diverse nutrients thus providing balanced calories for the populace. However, the diets that LDCs obtain have little animal-related food sources, although the small amounts meet biochemical demands (Molnar & Iva, 2000). In return, the populace has managed to maintain proper health, thus reducing cases of diseases for instance obesity within its populace. Diets often vary with reference to regions with rural diets being healthful matched with urban diets. Urban diets are deprived since families depend on junk foods while rural families take up traditional diets that are considered superior. Though wealthy communities have most options regarding their diets; they often misuse these options and opt to take up the least nutritious meals or take up excessively. The diets vary with regard to economic capabilities, lifestyles and regional preferences. Diseases have an impact both at individual and societal levels since certain diseases may be communicable. Additionally, once a disease affects an individual, the society suffers since it cannot obtain the services that the individual offers within the community or other economical contributions. Therefore, diseases affect both the individuals together with the community that this individual serves. Currently, inadequate water supply has hit most regions across the globe threatening to trigger disease outbreaks commonly related to sanitation.
