Leadership Personal Issues and the Rules of Law - 1650 Words
Leadership Personal Issues and the Rules of Law (Other (Not Listed) Sample) Content: Leadership Personal Issues and the Rules of LawAuthorà ¢Ã¢â ¬s Name:Institutional Affiliation:Date:Examine the postsecondary education requirements for police hiring agenciesRecruitment, profiling, and training is imperative in any sector that involves workforce, but the process is so overwhelming in police services employment protocols in the US today. Historically, recruits were drawn from the position of previous military men habituated to discipline and self-control. However, the plan was abolished and required police recruits sort to be unrefined high school alumnae who had modest discipline or experience following commands. The police department changed the minimum age for fresh recruits from 20 to 22 years in 1995, as a way to recompense for the dilemma. Consequently, they made obligatory that the recruits ought to have two year's college credits merits or two years in the military (Nytimes.com, 2000). Nonetheless, there has never been consensus over the iss ues.Those arguing against the postsecondary education prerequisite hold that the requirement the unreasonably limits the current thin applicant pool by not including the otherwise other qualified applicants. In addition, they argue against the requirement as discriminatory in nature and therefore having a disproportionate negative blow on minorities because it provides unequal opportunities for secondary schooling. They also view that higher education does not entirely provide all the skills looked-for to execute the job since those skills come exclusively because of experience on the policing career (White and Escobar, 2008). On the contrary, those who support the requirement also have stern reasons for their stand. They believe that policing is a complex career, where knowledge and skills indispensable to do the job effectively can only be scholarly acquired in a classroom, and not exclusively through on-the-job experience. The society has become progressively more well-informed, and it is indispensable for police to keep tempo with the larger civic. According to proponents, postsecondary recruits are more mature and more-rounded and are likely to interact easily with the public to offer solutions with understanding rather that authoritarian approach. Consequently, they hold that those who learn criminal justice at higher institutions will bring a more in-depth acquaintance of the system, its diverse components, how it works, as well as the established hypotheses on the causes of crime (White and Escobar, 2008). As a final point, the proponents suppose that the modern policing has transposed towards a problem-based style that requires both critical and analytical skills to execute successful operation and such skills are obtained at college (White and Escobar, 2008).Considering all points above, I support that it is necessary for officers to possess post-secondary education. Not because, the concerns shared by the opponents of the requirement are not signifi cant, but for the fact that the modern policing system have changed and there is need to have officers who have enough comprehension of the system. The current expectations vested on the police force are greater than before. They are expected to prevent and resolve crime, disputes, and act in response with care and concern to societal needs. Additionally, the public anticipates them to utilize sophisticated investigative approaches that can engage the community, and offer protection against the ever-evolving threats of terrorism. Even though the substantiation of postsecondary education to improved policing performance is diverse, it is undeniable that the emergent skills necessary for effective police service delivery particularly in 21st century are developed in class. With disproportionate impact concerns, the 1991 police executive forum sustained that there is an adequate pool for majority and minority postsecondary men and women with an interest in police recruitment. Postsecon dary education makes candidates more attractive, and once employed, promotion and income increases are often attached to their success (White and Escobar, 2008).Differences between arrest, searches, and seizure with or without warrant: The police operation in criminal investigation in the USA involves arrest, searches, and seizure practices, all conducted to validate if one is culpable of an offense. Both operations are executed either with or without warranties but with due consideration of the law. Despite the three operations having same objective of obtaining or unearthing evidence needed to hold one as either guilty or innocent, they both have differences. The foundation for either a warrant is justifiable is properly laid in the Fourth amendment that is a ratification to uphold the US Bill of Rights (Spiotto, n.d). The 4th amendment provides the foundation for upholding peopleà ¢Ã¢â ¬s rights as regards to arrest, seizure, and searches either with or without a warrant as ou tlined in the Bill of Rights. The amendment offers protection to private individuals against governmental unreasonable searches, arrests, and seizures in four constitutionally confined or protected areas (Spiotto, n.d). They include persons- unreasonable, houses, papers and effects including individual possessions such as clothing and automobiles.The warrantless arrests in a public places are allowed to individuals for a felony arrest, even though the officer arresting suspect had sufficient time to obtain a warrant, so long as the officer deems there is probable grounds that the suspect has committed the an offense. However, felonies arrests in private places or not open to the public require a warrant, unless the arresting officer is hot pursuit of a fleeing criminal (Justia Law, n.d.). Further, the fourth amendment permits warrantless arrest for transgression committed in police officer's presence. Contrary to warrantless arrest operations, the fourth amendment application to sei zure is not mandatory that a detention be a prescribed arrest in as a way of complying with the requirements of warrants. Therefore, unlike arrest, the officer must show some justification to validate the seizure (Nolo.com, n.d.)As described in the fourth amendment, police can search only specific places as prescribed in the warrant draft. For instance, an officer cannot search a backyard or a garden if the warrant specifies a search in the house. Nonetheless, that does not imply that officers can only seize the items scheduled in the warrant, for if in the line of the search, the officers come across an evidence of a crime not in the warrant list, they can still seize it. Contrary to this provision, a warrant is not necessary in case of consent searches. This is the case where the owner of the premise to be searched or property to be seized gives consent (Nolo.com, n.d.). If the law enforcement limits their seizure or search to only what an individual agreed to, the search is valid . However, courts do not necessarily oblige that the law enforcement request for consent before searching anywhere, for they find that the preliminary consent was enough to rationalize whatsoever search the officers carried out, so long as the officerà ¢Ã¢â ¬s explanation is sensible.Packerà ¢Ã¢â ¬s crime-control model and the due process model: The principle guide to the execution of criminal justice in the US is a process characterized with tension following the varied reaction to how a particular crime was administered. In one of his influential book, a Stanford law scholar, Prof. Herbert Parker described the US criminal justice system as the upshot of two competing stances, the crime control, and due process justice models (Goldstein, n.d). The crime model of administering justice vests a high precedence on reducing criminal doings in society by mounting the powers of law enforcing personnel and the prosecuting team. The due processes approach emphasis on an individualà ¢ â⠬s rights and freedom and is anxious regarding the overwhelming authority and influence of the administration over the individual. Amid tensions, the models have the same objectivity as the US government equally funds both (Goldstein, n.d).According to Packer, the crime control approach is construed as a conservative strategy of combating crime for it focuses on protecting the public from criminals by flexible criminal demeanor and justice. In addition, this style stresses stringent and swift reprimand for crimes and from this stern adherence are societal benefits that include arresting the fear in criminals that they will be unsympathetically punished. In doing so, the model envisages at dispensing justices in the criminal system as hastily as possible (Goldstein, n.d). The swiftly criminal justice is so imperative that the proponents of this model will not mind the expansion of court powers and subsequent police and prosecution powers in handling the cases. In contrast, due process is perceived as a liberal criminal justice approach and shows favoritism to criminalà ¢Ã¢â ¬s rights. Packer notes that this approach functions under the precept that accused are innocent till proven guilty. The argument by the opponents of this model is that, it sets numerous obstacles in the way of realizing justice (Goldstein, n.d).Professor Packer refers the criminal control model as resembling an assembly line (Goldstein, n.d). By this, he means that the model vests much reliance on the capability of undercover and prosecutorial officers, performing in a familiar setting in which their individual skills are given full influence. Such is to bring out and recreate a reasonably accurate account of what really took place in a supposed criminal incident (Goldstein, n.d). Conversely, the due process discards this argument and replaces it with a view of informal, non-adjudicative evidence finding that stresses on t...

Medical School Admissions Whats the Deal with New Medical Schools
The practice of medicine has been going on for as long as individuals have been affected by disease. As the population continues to age and technology continues to grow, the need for medical professional and the drive to become physicians continues to grow. Despite the growing need for physicians and growing interest in pursuing a career in medicine, aspiring MD applicants may have noted that the number of medical schools to support training didn't grow for a long time. Between 1986 and 2005, there has been only a single school accredited. Additionally, two schools in Philadelphia merged and one closed, leaving the final number at 124 accredited medical schools across the country. Why are there so many new medical schools all of the sudden? You may have noticed that in recent years, a number of new medical schools have been opening. Between 2005 and 2012, the medical education system saw a HUGE increase in the number of medical schools, rising from 124 to 141. As the number of medical schools continues to grow, it may be worthwhile to consider one of them when making your decision. In our post, weââ¬â¢ll give you some things to consider when deciding to go to medical school. New vs. Established? How do you know if new medical schools are the right fit? Are you ready to forge a new path in medical education? Here are some things to consider: 1. Think about class size! The most established schools have class sizes ranging from 100-150 students each year. One of the nice things about these new medical schools is that the class sizes are smaller. In their beginning years, theyââ¬â¢re numbers are usually about half (or less) of the more established school. Are you a self-directed learner or would you benefit from more hands on teaching? Ask yourself what works best for your education. 2. Where do I do my clinical rotations? The major medical academic institutions are associated with teaching hospitals. They have trainees ranging from medical students to fellows and everything in between (RESIDENTS). What this means, is that at level of training, each individual is accustomed to teaching medical students. This is where you will learn the nuts and bolts of the clinical profession. The newer schools will generally be associated with community hospitals. Inquire as to the level of training supported at each institution associated. Will you be at a hospital with residents in addition to attending physicians? If so, this means that they are familiar with teaching students, and can help you along your path. Additionally, some schools, like School of Medicine at Hofstra University actually are associated with research institutions, and actually even have an MD/PhD program. You want to make sure you can pursue all your interests as you learn and train. 3. Can I rotate through a department I am interested in? The other question with regards to clinical rotations is can you rotate through a department to make connections in your future specialty. If you have a burning desire to be a dermatologist, but there is no significant dermatology department, then a newer medical school may not be a fit. It is worth inquiring if you can rotate through such departments in other institutions. These are just a few things to consider when on the road to medical school admissions, or even MD/PhD admissions. If you're not sure, Cambridge Coaching's application consulting service can help you break it down and make an informed choice. ;

Nitrogen (N2)ââ¬Its Discovery, Danger and Uses
Nitrogen is the primary gas in the atmosphere. It makes up 78.084 percent by volume in dry air, and that makes it the most common gas in the atmosphere. Its atomic symbol is N and its atomic number is 7.à The Discovery of Nitrogenà Daniel Rutherford discovered nitrogen in 1772. He was a Scottish chemist and a physician with a passion for understanding gases, and he owed his discovery to a mouse. When Rutherford placed the mouse in a sealed, enclosed space, the mouse naturally died when its air ran low. He then attempted to burn a candle in the space. The flame didnt fare well either. He tried phosphorous next with much the same result.à He then forced the remaining air through a solution that absorbed the carbon dioxide that remained in it. Now he had air that was devoid of both oxygen and carbon dioxide. What remained was nitrogen, which Rutherford initially called noxious or phlogisticated air. He determined that this remaining gas was expelled by the mouse before it died.à Nitrogen in Natureà Nitrogen is a part of all plant and animal proteins. The nitrogen cycle is a pathway in nature that transforms nitrogen into usable forms. Although much of the fixation of nitrogen occurs biologically, such as with Rutherfords mouse, nitrogen can be fixed by lightning as well. Its colorless, odorless and tasteless.à Everyday Uses for Nitrogen You may regularly consume traces of nitrogen because its often used to preserve foods, particularly those that are prepacked for sale or sold in bulk. It delays oxidative damageââ¬ârotting and spoilingââ¬âby itself orà when combined with carbon dioxide. Its also used to maintain pressure in beer kegs.à Nitrogen powers paintball guns. It has a place in making dyes and explosives.à In the health care field, its widely used in pharmacology and is commonly found in antibiotics. Its used in X-ray machines and as an anesthetic in the form of nitrous oxide. Nitrogen is used to preserve blood, sperm and egg samples.à Nitrogen as a Greenhouse Gas Compounds of nitrogen, and particularly nitrogen oxides NOx, are considered greenhouse gases. Nitrogen is used as a fertilizer in soils, as an ingredient in industrial processes, and is released during the burning of fossil fuels.à Nitrogens Role in Pollutionà Sharp rises in the number of nitrogen compounds measured in the air began surfacing during the Industrial Revolution. Nitrogen compounds are a primary component in the formation of ground-level ozone. In addition to causing respiratory problems, nitrogen compounds in the atmosphere contribute to the formation of acid rain. Nutrient pollution, a major environmental problem in the 21st century, results from excess nitrogen and phosphorous accumulated in water and air. Together, they promote underwater plant growth and algae growth, and they can destroy water habitats and upset ecosystems when theyre allowed to proliferate unchecked. When these nitrates find their way into drinking waterââ¬âand this sometimes occursââ¬âit presents health dangers, particularly for infants and the elderly.
