United Nations and USA Interventions Essay Example | Topics and Well Written Essays - 1250 words

United Nations and USA Interventions - Essay Example As a result, intervention in conflicts become an important part of it work. The United States of America is a nation that is made of states occupying the Northern part of America. The making of United States and its ascension to world superpower signifies a path full of conflict. After the Second World War, it emerged as one of the powerful states in the world and the end of cold war era brought a new world order with the United States as the only superpower in the world. Therefore as the only superpower in the world, the United States has had an upper hand in most of the world affairs. As such there are many instances where United States has intervened in conflicts but also in times when there was not intervention which was needed. (Shah 2008, p. 3) Intervention can be considered as a form of arbitration which is meant to bring the conflicting sides together or to mitigate the situation. There have been many forms of interventions in the world depending on the nature of conflict at hand. An intervention is supposed to be in interests of protecting the welfare of all the parties involved or in interest of protecting one of the parties that cannot stand the strength of the other in the conflict. There have been raging arguments concerning the provisions of the UN charter on intervention with conflicting sides arguing about the need to use military intervention in order to bring peace to warring parties and opponents arguing that this has not been provide by the UN charter on intervention and it amounts to violation of human rights. (Shema 2005, p. 1) Throughout history, there have been instance where thousands of innocent citizens have been slaughtered or displaced in the eye of the international community with same kind of argument prevailing. In 1994 thousands of Rwandans were slaughtered and millions of others displaced as the international community watched and the response was that Rwanda was a small unknown country. Since 2000, millions of people have been murdered in Darfur region of Sudan and other displaced as the world watches. These are some of the instance that has called for intervention by use of force in order to end such a crisis. Therefore the overall aim of any intervention is to protect the civilians from sufferings that they may be undergoing especially when the cause can be traced back to a political conflict. Historical interventions of the UN and US Since 1990s, there have been increased humanitarian interventions in the world. This has been due to increased incidence of conflicts and the traditional political system collapsed and countries tried to position themselves in the changing world. There has also been struggle for independence and many political conflicts. When it was formed the UN has been able to intervene in a number of conflict in the world especially in the Middle East in 1948 in Israel, 1957 in Egypt, 1958 in Lebanon and Syria, 1964 in Yemen, 1973 in Israel, 1978 in Lebanon, 1991 in Kuwait, and many others. It has also been involved in intervention in Pakistan, Afghanistan and India in 1988 and 1990. It has also intervened in African in 1992 in Somalia, 1999 in Sierra Leone, 1999, in Congo and recently in Darfur. These are just but some of the instance that the UN has intervened. The number of times that the US has intervened in the world are countless same as the number of countries where it ahs intervened. The history of

The relationship between asthma medications and periodontal disease Essay

The relationship between asthma medications and periodontal disease - Essay Example Herein, the reasons asthmatic patients are more prone to gum disease will be discussed. As well, what asthmatics can do to help prevent tooth and gum decay will be a source of study. Periodontitis is a "condition characterized by inflammation of the periodontal tissues, leading to tissue destruction, bone resorption, attachment loss, and, in some cases, tooth loss" (Saver, Hujoel, Cunha-Cruz, and Maupome, 2007). Asthma, on the other hand, is a "common [breathing] disorder, especially in the industrialized part of the world" (Sulssa and Ernst, 2001). When asthma episodes, or "attacks" occur, many patients rely on the use of handheld inhalers, which deliver a corticosteroid medication from the mouth, into the airway. The inhalation of the corticosteroid causes a dilatation, allowing for more air to pass into the lungs. It would seem, then, that gum disease and asthma are unrelated, but the life-saving corticosteroid could, in fact, have a negative impact on oral health. Nebraska dentist Dan Peterson devotes a website to, in part, the link between asthma medication and periodontitis. In his section "Oral Health Changes in Individual with Asthma," it is written that asthmatic patients have an "increased rate of caries." Many things cause dental caries, or cavities, but asthma inhalers usually contain sugar, which is a culprit in tooth decay. The website also lists the problems of "reduced salivary flow due to inhaler use and increased prevalence of oral tissue changes" as other reasons that asthmatic face mouth trouble. Dry mouth, also called xerostomia, can be caused by inhaler use. It is problematic because it causes "tooth decay and gum disease and makes you more vulnerable to inflammation" (Schaaf and Higbee, 1993). An article in Harvard Women's Health Watch adds, "Persistent xerostomia is a serious and often uncomfortable condition that can jeopardize oral health. It makes eating and swallowing difficult, causes bad breath, and may irritate mouth tissues, leaving them more vulnerable to infection". The article goes on to explain that inhalers can cause a reduction in saliva. The moisture of saliva is absolutely necessary. Its decrease, which can also be caused by painkillers, blood pressure medications, antidepressants, etc., is cause for concern. Advice is offered to combat dry mouth. The article offers that over-the-counter products that increase saliva production are one way to go. It also suggests trying to drink lots of water, limiting sugar intake, and chewing sugar-free gum. Avoiding de hydrating habits like drinking alcohol, smoking, or consuming caffeine might also help when the use of inhalers make xerostomia a problem. Inhalers aren't perfect, but they are necessary. "Sustained use of inhaled corticosteroids reduces the risk of severe exacerbations requiring hospitalization as well as death from asthma and therefore provides a simple and effective tool by which to eliminate major adverse events for patients with this common disorder" (Suissa and Ernst, 2001). Since asthmatics can't ignore breathing problems for fear of gum disease, advice is offered for sustained good oral health. Peterson's website suggests frequent dental check-ups and cleanings. It also suggests fluoride treatments, a proper at-home routine, the

Interest groups and Political parties Essay Example | Topics and Well Written Essays - 500 words

Interest groups and Political parties - Essay Example Common good can be referred to as the goodness of an event or a phenomenon that is shared by all communities of a given society. Thus, keeping in view the roles played by interest groups and political parties, it can be stated that both the groups are conducive in working towards common good of a particular society and those elements which make up that society. However, this statement holds certain pre conditions, i.e. the interest groups are not self centered and political parties do not strive for gaining power only over all others. In other words, it is the intent behind the formation of these groups which comes into play and is considered extremely important. Motives, actions and desires yield goodness as long as the driving force behind them remains noble. Same is the case with interest groups and political parties. The reason of stating that the two set of groups are conducive in attaining or working towards the common good is that these groups provide a platform to the general public around through which people can raise their voices, share their opinions, take part in decision making process, highlight their concerns and problems and reach such decisions which are acceptable and beneficial for all. In this regard, work of Rousseau holds a special place. According to him, people should be "sovereign" and the government should only be there to implement laws. He believed that laws shall be enacted by direct democracy, which followed that each person should directly be involved in law making through a platform.

Success Factors in Supply Chain Management Essay Example for Free

Success Factors in Supply Chain Management Essay Supply chain management (SCM) works with the process flow of information as well as products from supply chain organizations. Development in technology facilitates organizations ability to coordinate activities for use of supply chain servicing. The Council of Supply Chain Management Professionals (CSCMP, 2011) defines supply chain management in the following way: Supply chain management encompasses the planning and management of all activities involved in sourcing and procurement, conversion, and all logistics management activities. Importantly, it also includes coordination and collaboration with channel partners, which can be suppliers, intermediaries, third-party service providers, and customers. In essence, supply chain management integrates supply and demand management within and across companies (p.1). There are four basic components within the supply chain management that are essential for SCM processes. First, ensure that to manage resource requirements, a strategy exists which the customers needs are met for services/products based on their strategic demands. Secondly, the appropriate business supply chain partners, in fact, are the ones that will provide the end product from materials, servicing requirements through payment processes, delivery of goods, pricing, and any other method by which the process will be measured. Third would ensure that operations is on board for ensuring the schedules take into consideration tasks for packaging, testing, process preparation, and delivery preparations. Lastly, logistics requirements are well thought-out, such as warehousing, orders, return processing, carrier/delivery service, and invoicing. SUPPLY CHAIN MANAGEMENT SOFTWARE PACKAGE COMPARISON For the SCM software package review, there were three companies in the comparison: SAP Supply Chain, PackManager, and IBS Enterprise. One area of concern was with PackManager whereby once installed technology support is not a provision. Daniels and Daniels (2012) indicate the areas of the five basic supply chain management activities which include plan, source, make, deliver and return. The comparison of the three SCM software packages above assist businesses in making an appropriate decision based on their specific needs. Each company had something that others may not have and, as a result, supports that one company may not be the viable solution for every industry. . To complete a comprehensive review of SCM software packages, the site which assisted with the compilation of data, FindTheBest.com (2014) CONCLUSION SCM is the dynamic managing of SC activities which take into consideration customers value as well as manage a viable benefit. The comparative review indicates that there are many choices in SCM software. Each of these will provide a †¦ supply chains in the most effective efficient ways possible (Handfield, P. 1, 2011). Wang et al (2009), further stated that the †¦problems, criteria, needs, alternatives and other variables will vary from one entity to the next, there is no universal solution (P. 95). In order to support the best choice for the appropriate SCM, then key factors should be quantified in the overall decision process.
