Need for School Security essays

Need for School Security essays Violence in schools has spread widely throughout the nation, leading to many problems among students, families, and residents of these areas. However, there are many ways we can stop or prevent future violence in schools. Having security in schools is a great possibility that would help reduce problems in schools. Recent national tragedies have placed security at the top of the priority list for many school leaders (Trump 1). Almost three-fourths of the United States teens are afraid of violent crime amongst their peers (Apfel 23). With all the people being injured or killed in school by guns and other weapons, more and more people are getting more weapons to bring to school in hopes of protection against all the other violence at schools. Since most schools have gotten medal detectors and scanners, they have cut down on the rate of having handguns in schools by nearly 58% (Glazer 5). Security experts have reported that there is no evidence that a metal detector will solve the problem of violence in schools (Apfel 22). Even with the gun laws, and medal detectors, people are still continuing to sneak guns and other weapons into the schools. CNN has confirmed the U.S. Secret Service has been coordinating a study of recent incidents of violence in the nations schools, focusing on motives and behavior behind school shootings. According to a report commissioned by Students against Violence, almost 50 percent of teens have noted the addition of on-campus police or security officers. Roughly the same number reported noticing enhanced physical security at school (Security Management). Violence has caused many problems. Many people have been killed or seriously injured because of violence. Progress of overtaking the violence in schools will not be made until school administrators define security goals and accept security as a part of professional discipline (Hylton). Every school district should have ...

French Politics and Institutions Essay Example | Topics and Well Written Essays - 1250 words

French Politics and Institutions - Essay Example In the Toulouse shooting there were four Jews killed outside of a Jewish school, three of those dead being children. Just like in the past incident, the Toulouse shooting sparked riots in France with the society divided between those who supported Bayne and those who condemn him. Therefore, other separate incidents similar to the recent shooting should work as a highlight and a warning sign rather than being treated as a lone incident. Unlike in North America where issues affecting the Jewish community there are low birth rates, intermarriages and assimilation, in French Europe, anti-Semitism is a social phenomenon rather than just a lone incident1. The strong outspoken French public take on the two incidents has worked in highlighting the similarity between both incidents. The society seems, just like in the first incident, to be very active in taking sides - either on the side of the victims or on the side of the perpetrators. The underlying crimes are based on hate. However, there have been recent twists to this anti-Semitism in that political and economic spheres have been introduced into the debate but the fact remains that anti-Semitism just like in those periods of 1890s still is strong if not getting even stronger in France. Even scholars have been thrown into different conclusions about the recent incident in line with the Dreyfus Affair in that some like Neocon John Podhoretz are declaring an alert that â€Å"Jews are being hunted.† Though an overtone, it seeks to highlight that the recent event cannot be looked at in isolation to the 1894 anti-Semitic affair because of the similarity between them. On the contrary Leon Weiseltier termed his article â€Å"Hitler is dead.† In essence, the writer is telling the Jews in the Diaspora that they should not panic. These two authors could be taken to be social representatives in the voicing of how society in France takes up positions when these issues are brought to light in the French public dom ain2. The fact that even those denying the latest shooting incident are referring to the contrast between the two incidents only raises concerns about the similarities between the incidents which are more than 100 years apart. It is therefore not uncommon to find political leaders in search of public support or mere social debate in quest to remain relevant talking about the two events and dragging anti-Semitism into the contemporary political and economic circles. Despite the country’s enormous steps in technology, economy and political spheres, the culture of anti-Semitism has remained deeply enshrined among some parts of the society. The recent shooting does not therefore represent a separate aspect of the French population but a rather serious social phenomenon. It can also be seen as a serious social evil because the shooter in the recent Toulouse shooting definitely was not even born when the Dreyfus affair was happening. Examination of the Ability of France to Divide O ver Issues The study has already established that one similarity between the Dreyfus Affair and the recent Toulouse shooting has been the characterization of the French public to divide into two different camps when social phenomena take place. Hence, while others openly support the individuals who perform the anti-Semitic activities such as the ones noted above, others strongly condemn them in equal matters. This has historically been the French scenario. Taking the scene in

Play and Learning in Early Childhood (A comparative study between Dissertation

Play and Learning in Early Childhood (A comparative study between Scotland and Saudi Arabia) - Dissertation Example In order to accomplish these research objectives, the researcher selected primary and secondary data collection methods. Primary research was conducted in the form of interviews at Cranstonhill Nursery School, Glasgow involving two staffs. On the other hand, secondary data was collected through past research papers, academic journals and newspaper articles. Primary data revealed that early year education based on learning through playing activities is a good step to improve the cognitive abilities of children. Secondary data analysis also confirmed the fact as majority of academicians and researchers agreed that in spite of exposing children to direct education; it is important to make them a part of early year education offering good amount of exposure and learning experiences. On the basis of these findings, it was concluded that countries like Scotland and Saudi Arabia has been offering great attention to develop more numbers of early year education but lacks uniformity. ... the end based on acknowledgement- Ludwig Wittgenstein The purpose and importance of every research is enhanced by the cooperation and support of many people.

Firm behaviour which seeks to give considerable weight to ethical Essay - 1

Firm behaviour which seeks to give considerable weight to ethical concerns must do so at the expense of profit. Discuss ma - Essay Example Having established a definition of ethics, the question as to whether or not a business can sustain very prominent ethical principles without sacrificing profitability requires significant examination. According to Milton Friedman (2003), a respected business theorist and philosopher, the only genuine goal of a business is to ensure shareholder satisfaction and earn a profit; this over all other objectives. Friedman’s view is that attainment of profit, by which some individuals in society believe this objective to be akin to greed and materialism, supersedes the demand for sustaining the highest standards of moral and decent behaviours. For many in society, however, this is deemed unethical behaviour requiring further focus on social responsibility. There is, however, ample evidence that both profit achievement and production of ethical behaviours can be effectively balanced. Why ethics and profit can achieve equilibrium Within a business dynamic, it is recognised that leaders who publicly exhibit high standards of ethical behaviour are more apt to gain trust from employee followers, making it more motivational for employees to follow the established mission and vision of the leader (Watts 2008; Resick, Hanges, Dickson and Mitchellson 2006). According to the literature, transparency and trust are two key dimensions for establishing a cohesive organisational culture (Barrett 2011). Since ethics and trust go hand-in-hand, theoretically the ethical leader will be able to establish an organisational culture that remains unified and consistently working toward modelling ethical behaviours that have been openly demonstrated by the leadership. Business theory and marketing theory, further, indicate that once a very cohesive and cooperative organisational culture has been established, it is easier for the firm to sustain competitive advantages that are attributed to human capital development. For instance, Armstrong (2007) indicates that once trust and cohesion have been established, employee followers of the ethical leader are more committed to attaining organisational goals and more loyal to the business due to the fact that the ethical leader was able to speak to the hearts and minds of employees. Why is this important to understanding whether ethics and profit can be balanced? When an organisation is perceived by external investors to sustain a very cohesive organisational culture, they are considered to be world class organisations with much more incentive for investment potential (Very, Lubatkin, Calori and Viega 1997). The ethical leader described in the aforementioned example has managed, theoretically, to build more loyalty and commitment simply by exhibiting ethical behaviours. Concurrently, the external investor now witnesses the human capital advantages of establishing a cooperative team environment and subsequently provides investment that assists the organisation in its long-term strategic plans and objectives, such as new ca pital machinery for production or improving the marketing function. In this example, ethical behaviours served as the absolute catalyst for improving the financial situation of the business. Without having exhibited ethical behaviours, the leader would not be creating an organisation

Reflective Essay on Empowering Healthcare Professionals

Reflective Essay on Empowering Healthcare Professionals This reflective account is going to explore a lecture that has changed my perception since the start of the nursing programme. I have chosen Gibbs (1998) reflective model to explore what I have learned, what my thoughts were before the lecture and changes. Therefore, to demonstrate an awareness of my learning outcome. I would also be covering how this has helped me to develop an understanding on what to do during my practical placement. The NMC code 2015 outlined standards and core values nurses must follow, therefore, our lectures focused around these to empower healthcare professionals to adapt to and deliver a quality service. The lecture I would be exploring emphasised on dignity, importance of dignity and how to encourage it. On a personal account, I thought I had a broad understanding of how to promote patients dignity. Nevertheless, after three hours of lesson on the subject, I have realized that there is a lot more to it. Dignity is a broad topic when properly studied. Dignity is a powerful tool that can determine a persons life and relationship with others suggested by Hinks, D. 2013. The poem what do you see? RCN, 2017, demonstrates the power of dignity. The poem represents a woman who is beseeching to be seen for who she is, not an old woman but someone who had lived a full life with feelings and emotions reinforcing the value of providing person centred care (RCN,2017). My feelings throughout the lesson changed considerably, leaving me to desire more of the lesson. Matti and Baillie (2011) proposed dignity as our innate value, merit and worth as human beings. To this end, the lecturer emphasized on respect making it clear that respecting people and making them feel worth is not just about caring for them, rather, it takes into consideration the whole process of how we approach and visually demonstrating dignity to the patients. I found that the NMC code (2015), stressed that as nurses, we have a duty of care to reach out for the physical, emotional, psychological, social and spiritual needs of our patients. So, give a holistic care by taking into consideration the individual as a whole. Hence, we need to prioritize patients care and dedicate time to them by preserving and promoting dignity through effective communication and supportive relationships. Emphasizing on these, it incorporated within me a sense of awkwardness and to realise how significan t it is for me as a person to be valued. Following the Poem What do you see? (RCN, 2017) I understood how patients are treated inhumanely. I felt like it is more dangerous to ignore patients emotion as this may have a huge impact on their personality It made me apprehended that, as a student nurse my responsibility is to work as part of a safeguarding team to raise concerns when I come across things that endanger patients worth and value according to the Local Government Association (2012). I found social care Act 2012 and CQC (2016) reinforcing on the link between dignity, quality and safeguarding indicating that the nurses, however, were not promoting dignity and therefore do not portray a good quality service so safeguarding is likely to decrease. The lecturer, also, underpinned the importance of personal appearance which connects to the concept of dignity because of the way uniform makes nurses feel and behave and how their appearance has an impact on patients supported by Chochinovs (2007) ABCD Framework (attitude, behaviour, compassion and dialogue) which reinforces essential things nurses need to be aware of when delivering care. Subsequently, this lesson appeared to pose more challenges. I felt highly challenged to question and evaluate on the type of staff I might be. I was challenged to think differently following Chochinovs (2007) self-awareness tool which got me thinking about if I would be able to provide a quality service to my patients while trying to promote dignity and what challenges I might face when dealing with safeguarding issues. However, after reflecting on myself and considering my attitude, behaviour, how I show empathy and compassion through communication, I felt confident to go out there and to demonstrate what I have learned with patients. I now feel like I am competent enough to fully and independently care for a person thus building a supportive relationship with them (Chochinovs 2007). Furthermore, this lecture helped me to comprehend the impact we as nurses can have on a patient as a person. In conclusion, dignity is how people feel, think and behave in relation to their worth or value. To treat someone with dignity is to show them as being worth and valued in a way that is exalt their diversity. Dignity may be endorsed or reduced by the physical setting, structural principles, approaches and conduct of others. When dignity is present, people feel in control, relaxed and able to make decisions for themselves, whereas when it is absent people feel devalued and lack control. Therefore, in my placement, I would do all the necessary things to ensure the value and worth of my patients, thus considering an approachable method of communication and rapport by making them feel at ease. Also, using person-centred care and empathy (RCN 2016). References: CARE QUALITY COMMISSION (CQC). 2010. Essential standards of quality and safety. London: HMSO. Chochinov (2007).

New England Vs Chesapeake :: essays papers

New England Vs Chesapeake Early English colonies in America hardly resembled the union of men and women that would later fight against England and build a new country. In fact, until the mid-eighteenth century, most English colonists had very little, if anything to do with the settlers in neighboring colonies. They heard news of Indian wars and other noteworthy events, not from the colony itself, but from England. The colonies in the New World appeared completely different and the prospect of any unity between them seemed impossible. The colonies in New England and the Chesapeake exemplify the many differences in the culture and lifestyles of the settlers, created mainly because of the fact that their founding fathers had held separate intentions when they came to the New World. The New England and Chesapeake colonies were both settled by immigrants from England, the New England colonies being founded by the English from East Anglia, an area in eastern England. Though this was an area thriving with small towns that they had generally liked, they decided to flee England due to religious persecution. Hundreds of families, men, women and their children, came in search of a New World where they could practice their beliefs freely. They founded colonies such as Connecticut, Massachusetts, New Hampshire, and Rhode Island as model Christian societies. Their cities upon the hills were guides, the lanterns, for those lost in the darkness of humanity, as John Winthrop meant by his famous statement. They formed a society of strict religious participation, actually very much resembling their homeland. In the beginning, many called themselves Puritans, and kept things very simple and plain, concentrating on what was important to them. They used the community to achieve t heir goals, building new towns and enjoying the social aspect of their religion. At the same time, they were committed to remain working hard to keep their community productive. They believed the â€Å"idle hands† were the devil’s workshops. An issue that really defined a split between the societies was the slavery conflict. The northerners in New England held true to their belief that every man shall be equal and no one should be enslaved, while the southerners in the Chesapeake area strongly believed in the use of slavery. At the same time the New Englanders worked to help end slavery by preaching to others about the injustices, they worked diligently to make education in their society strong.

Computers Will Soon Replace Books Essay

There has been a lot of talk lately concerning the possibility of computers replacing the position of books in our life. I believe it is truly possible. Many years ago, people used books for everything related to education. In fact, the human’s best source of knowledge and education was the book. But computers have gained popularity in a very short amount of time and everyone at least has one somewhere around their house. We have the need to use computers for everything. All we have to do is give the computer instructions and it does all the hard work for us. I am going to discuss the benefits that computer has to offer to its users. Firstly, computers are much better than books because a modern computer can hold a billion times more information than the average 400-800-page book. If you want to do a research about anything, it would take you at least an hour just to find the right book but by using a computer, you can find the same information in less than 5 minutes. Many people including me use the internet as a dictionary, finding definitions, so this way only takes the time to type the word. A laptop computer equal to the size and weight of a book holds data about any topic you can think of. A book only covers a specific topic. A computer can hold much more types of data than a book. When you carry one computer, you are carrying a hundred thousand books. Secondly, everyone would agree that an e-books cost much less to produce and less to buy than an actual paper books. The information in a digital format can be shared easily by email or by copying the files onto someone else’s computer or simply by transferring it into your USB drive. It is also easier to edit the information. This makes it overall more convenient for students who might not be able to afford one copy of a book each and who don’t want to make notes and underline points. Free information means at least cheap education. Who would not like a cheaper education? There are numerous websites like Google (search free textbooks in your subject area) and Google books, permit students with a limited budget to get what they want without having to spend large amounts of cash. Free e-books make education accessible and cheap thus more widespread. Last but not least, the most obvious reason why computers are making our lives better is by reducing the number of trees that are cut down for the production of books. I agree that an eBook is not 100 percent green and is far from it. But if you are comparing eBooks to other paperback books, eBooks certainly take the lead. According to â€Å"The e-Book Apocalypse† article, twenty-four trees are required to produce a ton of paper for printing books, and twelve are needed for a ton of newsprint. Thirty-five percent of those books printed are destroyed before they are even read. In 2009, eBook readers took off and the latest reading trend began to grow. In 2010, these reading devices became more popular and started sparking the attention of people everywhere. Some of this attention came from the idea that this new was a huge breakthrough in an effort to save our planet, which I find most definitely possible. To conclude, I understand change, whether it is for the good or the bad, is always a difficult and uncomfortable thing. That is the only reason why the whole world has not yet made the shift from traditional books to e-books. Now, there might be few advantages to paper. But I see a lot more advantages to digital. The fact that I now carry about a hundred books with me, wherever I go, that I can read whenever I want, outweighs any advantage a paper book could give me. Digital books are here to stay and there is no doubt that within a few years we will look at paper books as something saved from the past.

Differences of Descartes and Locke with Lockes casual theory of perce

Differences of Descartes and Locke with Locke's casual theory of perce Differences of Descartes and Locke with Locke's casual theory of perception Philosophy Part I: List at least four differences between Descartes and Locke on how we obtain knowledge. For Descartes, (1) knowledge relies completely on utter certainty. Because perception is undependable, (2) knowledge cannot come from our five senses. Descartes believes knowledge can come from experience and deduction. But for this philosopher, (3) he does not believe we gain knowledge from the outside world. Therefore it must come from within. In light to how we view things, Descartes believes that deduction ``can never be performed wrongly by an intellect which is in the least degree rational'', so deductive knowledge is (the only) certain knowledge. Such a system requires a basis of intuitively understood principles from which knowledge can be deduced. (4) He believes that there are some principles which are automatically known, just like the idea of the existence of ourselves and that of God's existence, these are principles which are ``revealed to [us] by natural light'' and ``cannot in any way be open to doubt''. In the end Descartes sees these principles as innate. On the opposite end, John Locke believes something completely different. (1) For starters, he does not believe that knowledge is certain, but that it is just is highly probable. He goes on to say that (2) knowledge comes from our fives sensations or our five senses. Those five senses come from the outside world. Locke disagrees with Descartes when he says that (3) knowledge comes from the outside world. (4) The biggest difference of belief of know we obtain knowledge is that Locke believes that we cannot have innate knowledge. Locke says that because everyone has different views of God?s existence, how is it that we were all born with some knowledge of God? These are some of the ways the two philosophers disagree on how we obtain our knowledge. Part II: Explain how Locke?s casual theory of perception works As stated above, Locke believes that we obtain knowledge through our five senses (the external world). Now I will show you how that theory works. He defines ideas as immediate results of thoughts or perception. Ideas are produced through virtue of object?s qualities. Those qualities are broken up into three types of qualities. The first type is our primary qualities. Those are primary because they are inherent. We are able to understand bulk, figure, number, and motion. Then comes in our secondary qualities. They give us the ability of understanding appearance such as color, texture, flavor, and shape. Our third type is the last piece of the puzzle. It gives us feelings we have never felt before such as pleasure &pain. When we feel something hot for the first time and it burns us, it teaches us to not do that again. That is an example of perception with our third type of quality. All of these combined give us the ability to perceive our world and show us how we obtain knowledge, better known as ?Locke?s Casual Theory of Perception?.

The History of Gravity and Aristotle

The History of Gravity and Aristotle One of the most pervasive behaviors that we experience, its no wonder that even the earliest scientists tried to understand why objects fall toward the ground. The Greek philosopher Aristotle gave one of the earliest and most comprehensive attempts at a scientific explanation of this behavior by putting forth the idea that objects moved toward their natural place. This natural place for the element of Earth was in the center of the Earth (which was, of course, the center of the universe in Aristotles geocentric model of the universe). Surrounding the Earth was a concentric sphere that was the natural realm of water, surrounded by the natural realm of air, and then the natural realm of fire above that. Thus, Earth sinks in water, water sinks in the air, and flames rise above air. Everything gravitates toward its natural place in Aristotles model, and it comes across as fairly consistent with our intuitive understanding and basic observations about how the world works. Aristotle further believed that objects fall at a speed that is proportional to their weight. In other words, if you took a wooden object and a metal object of the same size and dropped them both, the heavier metal object would fall at a proportionally faster speed. Galileo and Motion Aristotles philosophy about motion toward a substances natural place held sway for about 2,000 years, until the time of Galileo Galilei. Galileo conducted experiments rolling objects of different weights down inclined planes (not dropping them off the Tower of Pisa, despite the popular apocryphal stories to this effect), and found that they fell with the same acceleration rate regardless of their weight. In addition to the empirical evidence, Galileo also constructed a theoretical thought experiment to support this conclusion. Here is how the modern philosopher describes Galileos approach in his 2013 book Intuition Pumps and Other Tools for Thinking: Some thought experiments are analyzable as rigorous arguments, often of the form reductio ad absurdum, in which one takes ones opponents premises and derives a formal contradiction (an absurd result), showing that they cant all be right. One of my favorites is the proof attributed to Galileo that heavy things dont fall faster than lighter things (when friction is negligible). If they did, he argued, then since heavy stone A would fall faster than light stone B, if we tied B to A, stone B would act as a drag, slowing A down. But A tied to B is heavier than A alone, so the two together should also fall faster than A by itself. We have concluded that tying B to A would make something that fell both faster and slower than A by itself, which is a contradiction. Newton Introduces Gravity The major contribution developed by Sir Isaac Newton was to recognize that this falling motion observed on Earth was the same behavior of motion that the Moon and other objects experience, which holds them in place within relation to each other. (This insight from Newton was built upon the work of Galileo, but also by embracing the heliocentric model and Copernican principle, which had been developed by Nicholas Copernicus prior to Galileos work.) Newtons development of the law of universal gravitation, more often called the law of gravity, brought these two concepts together in the form of a mathematical formula that seemed to apply to determine the force of attraction between any two objects with mass. Together with Newtons laws of motion, it created a formal system of gravity and motion that would guide scientific understanding unchallenged for over two centuries. Einstein Redefines Gravity The next major step in our understanding of gravity comes from Albert Einstein, in the form of his general theory of relativity, which describes the relationship between matter and motion through the basic explanation that objects with mass actually bend the very fabric of space and time (collectively called spacetime). This changes the path of objects in a way that is in accord with our understanding of gravity. Therefore, the current understanding of gravity is that it is a result of objects following the shortest path through spacetime, modified by the warping of nearby massive objects. In the majority of cases that we run into, this is in complete agreement with Newtons classical law of gravity. There are some cases which require the more refined understanding of general relativity to fit the data to the required level of precision. The Search for Quantum Gravity However, there are some cases where not even general relativity can quite give us meaningful results. Specifically, there are cases where general relativity is incompatible with the understanding of quantum physics. One of the best known of these examples is along the boundary of a black hole, where the smooth fabric of spacetime is incompatible with the granularity of energy required by quantum physics. This was theoretically resolved by the physicist Stephen Hawking, in an explanation that predicted black holes radiate energy in the form of Hawking radiation. What is needed, however, is a comprehensive theory of gravity that can fully incorporate quantum physics. Such a theory of quantum gravity would be needed in order to resolve these questions. Physicists have many candidates for such a theory, the most popular of which is string theory, but none which yield sufficient experimental evidence (or even sufficient experimental predictions) to be verified and broadly accepted as a correct description of physical reality. Gravity-Related Mysteries In addition to the need for a quantum theory of gravity, there are two experimentally-driven mysteries related to gravity that still need to be resolved. Scientists have found that for our current understanding of gravity to apply to the universe, there must be an unseen attractive force (called dark matter) that helps hold galaxies together and an unseen repulsive force (called dark energy) that pushes distant galaxies apart at faster rates.

Evolution of lactase gene in homo sapiens Term Paper

Evolution of lactase gene in homo sapiens - Term Paper Example Genetics and molecular studies of genes presently and in the past are pointing towards an evolutionary cause behind its persistence in adults. In order to prove that something is a product of evolution, one must demonstrate that a favourable trait mutated. Additionally, one must show that the trait was transmittable to offspring and the environment favoured that trait. This may necessitate genital analysis of pre-historical data as well as present ones. Furthermore, these patterns ought to be analysed in relation to the behavioural or cultural patterns of the subjects as it could affect the adoption of the trait. The paper will look into these dimensions in order to illustrate the evolution of the lactase gene. Advantages and disadvantages in a population Lactase-phlorizin hydrolase (LPH) is the enzyme responsible for the digestion of lactose in Homo sapiens. Lactase activity in the intestines depends on the maturity of the person under consideration. Infants between two to eleven mo nths old have some of the highest activity levels. As a child reaches the age of five, lactase activity reduces, and this may continue in subsequent times. Therefore, the amount of the LPH enzyme will reduce because a person stops suckling or consuming lactose. Conversely, some adult populations continue to maintain high level of lactase activity, especially those with North European descent. This persistence of activity is an evolutionary development that coincides with the development of the dairy industry in most parts of the world (Grand et. al. 618). It is thus advantageous to ingest lactose in adulthood because this will not limit the person’s dietary intake. They will have the freedom to consume milk without dealing with health challenges. Prior to the domestication of animals, adult populations did not need the lactase enzyme. Therefore non persistence was the available state. However, this dramatically changed when animals started providing milk to the human populati on. It became genetically advantageous to retain the lactase enzyme in adulthood. Since only persons with this enzyme can enjoy the nutritional benefits of milk, then lactase persistence is beneficial. Culture dictated gene adaptability and advanced evolution (Hollox 267). Milk is nutritionally beneficial to the human body because it a rich source of calcium. Therefore, consumption of the beverage would protect one from bone-related diseases such as osteoporosis (Swallow 208). Rickets is an undesirable condition that also emanates from the lack of calcium. It is a selective force that favoured the ingestion of milk. The lack of the lactase enzyme in adults leads to a number of difficulties when dealing with the digestion of milk. Once such individuals consume milk, the lactose in milk will stay undigested. No alteration in blood glucose will be detected if a test is done. Instead, the product will enter the colon and be fermented. Fermentation causes the production of gases such as hydrogen and fatty acids. This is possible through the action of bacteria in the gut. Usually, persons who are lactose intolerant will suffer from bloating or gaseousness, diarrhoea, nausea, cramps and discomfort after taking milk. The gases that are produced after fermentation can be detected through portable hydrogen analysers (Itan et. al. 8). Therefore, it is highly desirable to be lactase persistent. All the complications that emanate from fermentation would be absent. Swallow (207) highlights some potential risks of having

Advertisements, Billboards, and direct marketing would be used as an effective promotional strategy.   Explicit content would be avoided during advertisements and emphasis would be given on opinions from females who have used the drug.

The product would be available without a doctor’s prescription hence Super Stores would also be able to sell the product. This is due to the success of Viagress both for women who have difficulty in sexual arousals and who do not. Modes of Entry This would be not an easy task as the product is being launched for the first time and as the success rate is 8 out of 10 women it might be possible that the 20% can be the first time users, hence a safe path would be selected to penetrate the market. A major advantage to Viagress is the huge chunk of market that is available for them to take over. The organization would first show and explain the success of the drug Viagra for males and then explain functions of Viagress in order to spread awareness among the people about what the product does.
