National Broadband Network or NBN is a network that is based in Australia. It has been proposed to develop it further with a constant increase of access to the customers (Wong, 2009). There have been some controversies over how NBN will be seen according to political and economic viewpoints, but overall, there are several positive and negative aspects that can be established. The positive sides include that access to data and people’s awareness of the matters while the negative factors relate to the cost and risk in the amount and practicality of usage (Kim, 2010). The way users gain access to information has become one of the key points in the modern world. The base promise of NBN is that the speed of access will be enormous, providing the population with one of the most advanced technologies. Also, there are plans to provide access to a great number of people that will include as much of the population as possible (Shilling, 2004). This will give a chance to improve the infrastructure, as well as awareness of the local matters. There has even been support from politicians, as it will provide better organizations and framework throughout the population, maximizing the interconnection between the different social divisions. But some of the disadvantages are also present and these relate to the way people become dependent on technology in almost all aspects of life. The development of technology has drastically changed the world. As people are unable to calculate the rates of progress, it is impossible to determine what changes will be brought about with an even greater increase in technological advancements. This can turn out as a failure to all the money invested. Some estimates have shown that the implementation of the new system will cost billions of dollars (Picot, 2010). This does not fare well will politicians and the economic agendas that are so dependent on the budget. Any innovation can be seen as a part of the greater progress, but it is a very risky matter where many people can be negatively affected (Green, 2002). At the same time, there are talks about the control that is exhibited by the user. The access to the information might put a major dent into the society. The private information and the communication itself has become a public occurrence where people put their lives out on the public viewing without any concern for security or privacy. Of course, there are positive sides, as people can become better known by the surrounding population and bring benefits to those who are interested. It is rather difficult to estimate the affects of such a change to a society that did not have the sort of technology previously (Restivo, 2005). Even though technology has helped people in a lot of ways, a person must realize its drawbacks and balance the use of technology with the physical interaction with others. The balance must be kept for technology to be helpful instead of detrimental. It is important to keep in mind that technology is not always error proof, thus reliability is a relative concept. There are many examples that show how technology has proven to be a negative influence on society, but people still continue its use. S
Introduction The degree of water pollution in the Los Angeles Metropolitan area is very high. This has led to its watershed having some of the most polluted water in the country. If the situation is left unattended, the quality of water in the watershed can be expected to get even worse as the metropolitan experiences population growth and greater industrial activity. Action therefore needs to be taken to contain the problem of pollution, which has caused the Los Angeles Metropolitan watershed to be one of the worst water sources in the US. To alleviate the problem and consequently limit its social consequences in the metropolitan area, the following solutions can be implemented. Solutions Growing Plant Cover An increase in the plant cover in the metropolitan area can help mitigate watershed pollution. At the present, impervious structures dominate the LA Metropolitan area and the amount of plant cover is negligible. Action should be taken to counter the negative impact that impervious structures have on the water quality in LA’s Metropolitan watershed. Since it might not be possible to remove the existing or prevent the future construction of impervious structures, a feasible solution could be to increase the number of plants and trees in the urban settlement. Pincetl declares that for cities to remediate some of their own environmental impact, they will have to make use of nature’s services (43). Increasing plant cover is one solution that can yield immediate positive results in the urban setting. To begin with, planting more trees and plants in the cities will help mitigate pollution by using the natural purification capability of plants. Plants can absorb pollutants such as heavy metals, which are present in the water, therefore performing natural purification. The water quality is therefore increased due to the purification process of plants and trees. In addition to this, plant cover will reduce the level of runoff that gets into the city’s storm drains. Dallman and Spongberg confirm that plants are capable of absorbing some of the water that flows as runoff during downpours (232). As such, a lower volume of contaminated water will make its way into the watershed area. Implementing this solution may be hampered by the lack of empty land in the Metropolitan area to be used for planting trees. This challenge can be overcome by making use of the available space at public parks and household backyards to plant trees and vegetation (Pincetl 43). Such action will enable the city to enjoy the environmental benefits of plant cover without foregoing the convenience that impervious structures offer. Protecting Catchment Areas A solution that proposes to bring significant reduction in the rampant pollution currently experienced in the Los Angeles Metropolitan watershed must consider the protection of the wetlands in the area. Due to the increase in population within the Los Angeles Metropolitan, wetland areas have been arbitrarily destroyed. Urban developers, who convert the wetlands into commercially via
Abstract Company “SunEarth” prepares to penetrate the intensely competitive but lucrative institutional and residential markets for grass mowers. Given an R & D breakthrough with a power train that runs completely on bio-fuels and features other environment-friendly innovations, the marketing plan must now address itself to deciding on the most promising target market segments, value proposition and positioning alternative. The company also wonders whether the timing is right since a weak domestic housing market has already depressed demand in what is otherwise a mature product category. Introduction The lawn mower emerged, surprisingly enough, in the middle of the Great Depression. While inventor/entrepreneur John Deere convinced initially-skeptical farmers about the virtues of working the fields with his tractors, Americans already venturing into a suburban lifestyle readily embraced the first rotary-blade, push-type lawnmowers and gave up forever the crouching and bending that attended keeping lawn grass trim with handheld scythes and machetes. The product category began the long-run growth phase of its product life cycle when the post-World War II Baby Boom generation arrived and with it, demand for housing not just anywhere but in suburban housing tracts with plenty of greenery. Explain the components of a marketing strategy The components of a marketing strategy for a new line of lawnmowers rest on engineered product attributes, a situation analysis to spotlight opportunities and constraints for a late entrant, formulating strategy that leverages strengths against opportunities while neutralizing weaknesses or rendering them irrelevant, and formulating the appropriate marketing mix. (Armstrong and Kotler, 2006). Today, the lawnmower industry has grown into a robust $15 billion business that has attracted dozens of domestic brands and a number of imports as well. The basic design has evolved greatly from the 1930s to include safety housing, “dead man” safety switches, gasoline-powered engines that made almost as much noise as the early rotating-blade models, ride-on models and lately, battery-powered carts. The traditional spectrum of positioning strategies have included brand equity, price, functionality, safety, cutting height adjustable down to 1 centimeter from ground level, comfort and ergonomic features, the latter two applicable to ride-on models. Leading brands John Deere, Briggs & Stratton and Toro are highly established. Having been responsible among themselves for all the innovation since stringent blow-down and other safety features were introduced by the federal government in the 1960s, they have a solid hold on the institutional, premium- and moderate-price tiers of the market (Outdoor Power Equipment Institute, 2009a). Hence, producing a parity lawn mower with a few cosmetic enhancements and optin
Introduction A non-governmental organization can be defined as a unit or association that is mainly operated for the interests of the members and the public. It is not created by the government although it may cooperate with it in some instances. Most non-governmental organizations are established to serve the public as opposed to being there for private benefit. They are known for their emphasis on promotion of humanitarian issues, provision of development aid and sustainable development among the people they serve (Sundstrom 2006). Development on the other hand entails the systematic use of knowledge (technical and scientific) to make some progress through achievement of specific objectives or needs in the society (Dale 2000). This piece of work looks into non-governmental organizations and their contribution towards development. NGOs and Development According to Welch (2001), Non- governmental organizations and their activities have been faced with a lot of controversy in regard to whether they make any positive efforts towards development or not with some individuals and agencies arguing that they use funds they get from the government and other donors in an inappropriate manner while others state that they have been very effective in promoting development. All in all, it is evident that most non- governmental organizations have done great in the society especially in the elimination of poverty related issues which are considered as a drawback towards the process of development (The main goal of development is usually the alleviation of poverty and hence non-government organizations have played a primary but major role in the development process) (Narasaiah 2005). This has been achieved through charitable activities aimed at uplifting the status of people in the society and empowering them in a great way such that they are able to live a better and more comfortable life free from problems associated with poverty and poor living conditions (Carroll 1992). Apart from alleviating poverty, non-governmental organizations are involved with various roles and responsibilities, for instance, research work aimed at gathering new ideas and knowledge that can in one way or the other promote development, participating in various negotiations with various bodies and donors on behalf of the community, contestation for the sake of the public, lobbying or advocating for the public where need arise as well as service delivery whereby the non-governmental o
Abstract Different locations experience security issues in the course of carrying out the day-to-day operations. Great care needs to be observed in order to avoid losses that result due to neglect or failure to take the necessary preventive measures. Theft is a serious problem of security that needs to be taken care of by employing experienced security guards and using videos in areas where business is carried out to ensure the movement of customers are monitored so that those who commit a crime can be noticed easily. The three locations discussed below include; grocery store, Bank of America, and Wal-Mart all of which are affected by various security issues that need to be taken care of for all the activities to run smoothly without encountering losses arising due to lack of adequate security measures. Grocery store Grocery stores put effort to be successful in a competitive industry by minimizing losses and maximizing their profits. These stores are affected by employees stealing goods and shoplifting by customers. The loss that may be incurred can be kept under control by using brand names on the products so that cases of loss due to theft can be easily identified. Technology such as an electronic system for controlling costs is also important in areas where sales are made. Videos are used to monitor the movement of goods and how customers carry out their shopping so that any goods were taken from the store pass through the cashier for payment to be made immediately. If any case of cheating is noticed through the video, it should be dealt with on the spot so that the customers may not go out of the grocery store without paying for the goods and explaining why they decided to disappear without settling their bills. The person who is assigned to monitor the movement of goods through the video should have enough experience of the area he is assigned to take care of so that he does not take a lot of time before tracing where theft has been detected. There are places where criminal activities are detected most of the time; remote guards should be in a position to communicate with other employees to ensure that all the criminals are caught and dealt with accordingly. All the customers who visit the grocery should use a shopping cart or basket in order to prevent the people who go to the store only to browse and make a comparison of prices without purchasing anything. Those who guard the grocery store are supposed to have stun guns to arm themselves to ensure that all the activities carried in the store are properly guarded and no intruder should get in without permission. (Kenyon, 2002 pp24-25) Bank of America (Jay, 2002 pp34-35) found that, Bank of America experience cases of bank robberies that require police to be employed. The police should be experienced in detecting cases of robbery if there is suspicion that there is planned robbery. Internet alerts are important so that the entire bank can be aware of security issues that affect operations of the bank and be prepared in advance to deal with them or stop them before their occurrence
Background Nutritional Importance of Omega-3 Fatty Acids and Docosahexaenoic Acid Of a large number of fatty acids of high biological value to the human body, the most notable are omega-3 long-chain polyunsaturated fatty acids. This is the main component of fish oil, which, when consumed by humans, has a positive effect on the construction properties of cell membranes and blood vessels. It should be recognised that these molecules alone cannot be synthesized in the body, and consequently, the person has to eat them with food to maintain a full diet. One of the most important representatives of polyunsaturated fatty acids is docosahexaenoic acid (Echeverría et al. , 2017). An adequate amount of these molecules in the diet positively correlates with the formation of brain and eye structures of the embryo, as well as postpartum functional development of the child. Despite the severe study of polyunsaturated fatty acids, among researchers, there is still an established opinion about the daily norm, which is necessary for human consumption. Omega-3 fatty acids (2019) indicates a daily requirement of 1.6 g of acids for men and 1.1 g for women. Of this amount, 250 mg of the substance should be docosahexaenoic acid (Tressou et al. , 2019). In this context, a study of the sources that supply the most significant amount of DHA to the body draws attention: according to Omega-3 fatty acids (2019), this is Atlantic salmon. At the same time, no docosahexaenoic acid is found in the composition of natural vegetable oils, although its sufficient amount could solve the problem of creating a complete diet. The increased emphasis on omega-3 fatty polyunsaturated acids is becoming a defining goal for nutraceuticals in the coming decades (Panse and Phalke, 2016). For this reason, special attention should be given to genetic modifications of existing plant materials to produce foods rich in fatty acids, and in particular DHA. Status of Knowledge on Genetic Modifications of Vegetable Oils The definition of the crop used as an object of genetic manipulation is of primary importance in the search for alternatives to fatty acid production. It should be admitted that the prevailing scientific literature is devoted to the modification of Canola, a plant with low levels of omega-9 fatty acids. In the context of the importance of genetic manipulations with Canola, it should be noted that vegetable oils derived from this crop have high nutritional and commercial value, with the potential to reduce serum lipid deposits (Ghobadi et al. , 2019). On the other hand, the technical grade of such oil has found full application as a biofuel to replace traditional counterparts in diesel engines (Ge, Yoon, and Choi, 2017). Vegetable oil from Canola is incredibly essential for humans, and therefore, its modifications are justified. Traditionally, the authors use similar technologies to insert genes of interest into the Canola genome. In supporting document 1 (2017), the authors of the study proposed a transformation transfer of a cassette of seven genes isolated from
Introduction “The Shunnamite” is a short story from the book written by Ines Arredondo, Underground River and Other Stories: the Shunammite. The title “ The Shunammite ” preempts the details of this particular short story because it is derived from the Bible in the book of 1 Kings 1:1-4. Here, King David had grown old, and his years on earth had been long. He was constantly sick and always cold. His servants, therefore, decided to look for a young virgin who would lie beside King David in the hope of fulfilling and inducing some of the old king’s deepest desires. After looking throughout Israel, Abishag, a Shunammite woman, was found, and she was brought to the king to comfort him. From the beginning of the short story, Licha embodies purity and innocence when she comes to attend to her uncle. However, she soon gets entangled in an abusive marriage to meet her family obligations. The summary of “The Shunammite” short story shall be examined in this essay. It is through characterization that one gets to understand the predicaments of the protagonist Licha, who must struggle with her wishes and family duty. Licha Through characterization, readers can empathize with Licha. One can feel what she is feeling and hence, feel the sense of reality projected in the narrative. One way in which characterization can be depicted is through the kind of dialogues that Licha has with the other people in the story. One realizes that she has the noblest intentions and often wants to look out for the interests of others before herself. On the other hand, as one continues, one sees the helplessness she is. For exa
The chosen article discusses the influence of urbanization on the growing obesity epidemic. At the same time, some may think that the inhabitants of suburban areas are more prone to obesity or being overweight. However, the findings of this study had shown an exciting rate of urban obesity (Lopez & Hynes, 2006). The study initially suggested that some suburban areas’ features can be tied to decreased physical activity and, as a result, a higher chance of getting an overweight population. Additionally, the study had proved that suburban areas’ features could not be connected to the higher risks of obesity since the inner-city population has higher rates of illness. The study suggested that the reason for the paradox is in some government decisions concerning different policies in the inner and outer cities (Lopez & Hynes, 2006). Moreover, the research suggests that infrastructure can also be partially blamed for the obesity epidemic (Lopez & Hynes, 2006). The study was conducted within different spheres to test all the possibilities; thus, the findings can be considered valid for that time. To combat these issues, the government should implement more choices both in urban and suburban areas. For example, in Japan, the country known as the place with one of the lowest BMI globally, healthy and unhealthy food choices are equally convenient. An average Japanese person is able to buy healthy lunch, unsweetened beverage, and relatively healthy snack, which is as convenient and fast as buying fast food. The Japanese have a developed transportation system, but most people enjoy using bicycles as a primary means of transportation since almost everything can be accessed via them. Therefore, the countries’ governments, where obesity is a grave issue, should make healthier options as available as harmful ones. Reference Lopez, R., & Hynes, P. (2006).
