It is obvious that someone has to action, but who?   Ã‚  Ã‚  Ã‚  Ã‚  Since the dawn of man people have used violence for entertainment. In Rome they had the Colluseum, nowadays we have the cinema. Violent films are being produced all the time, no one seems to care. Even though there aren't many people who are harmed from these films, there are a lot of children who do. It is a question of separating reality and fiction, and that is a problem for many children. After the Superman films in the 1980's, there were a series of children jumping off tall buildings, because they though they were Superman. As you grow older, this doesn't seem to be a problem any longer, even though there have been incidents were adults have started to kill people after watching a violent film.

It was introduced with the launch of Wolfenstein in 1990. In  «Wolfenstein » you are trapped in a maze among an army of nazis. You'll have to kill your way out. This kind of violence probably has a deeper influence on children, because they do the killings themselves. It is interactive violence. In several countries the follow-up game, Doom, was banned.

Cango Week 2 Video Analysis

CanGo Analysis Report Consultants BUSN 460-Team 1 CanGo Analysis Report Let me say first thank you for giving us the opportunity to evaluate your company’s operational process. It has been a tremendous experience to be in a company that started out small and grew to one of the leading businesses in the industry. CanGo does have a promising future ahead. During our evaluation over the past two weeks, we have noticed a few things that will be a problem in the future if not resolved. It seems that the company has been profitable by chance not because of planning. At this point we feel the need to work on the planning aspect and all that it entails. There are six key issues and recommendations that we have made that we know would help improve CanGo. Mission Statement The first issue is to have a mission statement for the company. This statement is the back bone of the company. Every employee will strive day after day with the main purpose of the company. Can-Go’s purpose is to provide a somewhat all inclusive service to entertainment needs via books, CDs, DVDs, and its new prospect online gaming. There seems to be no set direction for the employees to reference. Goals There are goals that Can-Go is going towards, but everyone isn’t on the same page. Unity among the employees is one of the most important aspects that you need to resolve. We witnesses during the management meeting about the online gaming idea, which no one seemed to be able to force their opinion or have an open decision to if the company should go forth with the idea. Andrew was very excited with the idea, but tried to almost push the company into the new market. You can’t go into a new market without seeing what is really involved in proceeding with the new move. SWOT Analysis One key thing that was missing when we observed CanGo is that Liz should have created a SWOT Analysis. SWOT stands for Strengths, Weaknesses, Opportunities, and Threats by conducting this analysis Liz would be able to see where the business was at in the current marketplace. It would also allow her to see where she could make changes in the company to increase profitability. A SWOT analysis allows you to view the internal and external factors of a company. The strengths should be a list of what makes CanGo better than the competitors. Liz made a great choice by giving her customers a $10 gift certificate and free shipping on the next order when they didn’t receive their orders in time for the holiday or received the incorrect order. They offer books and audio/visual entertainment online which is exactly where things are headed. They grew much faster than expected. By purchasing Webjouster they were opening up the door for online gaming. The download time for books and audio is fast. There are quite a few weaknesses that have been observed there seems to be a huge problem with organizational skills. There is no set vision for the company. The company as a whole could use a course on professionalism. When Warren delegated the responsibility to Nick for the online gaming being that this was a very important task it should have been handled better. He should have sat down with Nick and went over the goal and the timeframe that he had to get it done versus being vague about it saying they had weeks to get it done. CanGo also needs to improve their technology in order to offer the online gaming. There needs to be improvement in the Human Resource Department because there are people in positions that cannot meet the expectations necessary to fulfill their job requirements. The new opportunity they are faced with is being able to open up to online gaming. People have laptops, notebooks, and mobile phones with them at all times being able to entertain themselves with electronics is now a way of life. If the weaknesses are not addressed they will be threats because the competitors will be able to get in on the profits because of how unorganized CanGo is when it comes to handling business. I think there is room for CanGo to expand if they make the necessary changes to the company in order to stay on the track they are currently on. Short-term Objectives Liz failed to have a list of short-term objectives. By making this list she would be able to evaluate the progress her company is making. These short-term goals should cover the different functions of the company. These objectives should be SMART. That means they should be specific, measurable, achievable, realistic, and timed. They should sit down as a team and develop premeditated plans to meet these objectives. Feedback Loop As a company you are also missing the feedback loop. This is an important part of the strategic management process. It allows you to monitor the execution of every part of the strategic management process. It helps you know which goals and objectives are being met. Liz should sit down with her staff and make a list of short-term objectives and long-term goals. These goals and objectives should be evaluated after a set period of time to see how they are coming along with meeting their objectives and goals. After the goals and objectives are reviewed if they are not being met the process is reviewed and any necessary changes are made at that point. Teamwork There is a big organization problem that Nick has when dealing with getting a projection report for the new online gaming. Warren didn’t give him much to grow on. There were no questions by Nick to get more clarification. Nick’s reaction towards this great opportunity showed that he was impressed for this chance. Gail was not too convinced that he could do it. There seems to be a little rivalry between to the two, but working together as a team will only make the process go smoother. Warren didn’t divide the work load with the entire team. He should have known that it could be too much for only one person to handle. He didn’t make this new venture a joint effort by doing so he could have utilized everyone’s talents. He also didn’t give him a timeline on when this will need to be taken care of. Nick’s organization techniques are very poor. He didn’t even know how to prioritize the task that needed to be done. Pride shouldn’t stop you for asking for help. We were pleased that Debbie took the necessary time to help Nick produce a Gantt chart to help organize the tasks. This is what we like to see with all of your employees. A team is only as strong as its weakest link. Conclusion We would like to thank you for this opportunity to work with you. It has been a pleasure being able to be a part of the future of such a magnificent company. We can’t wait to work hand in hand with you to begin implementing these changes.

Rachel Carson Quotes on the Environment

Rachel Carson wrote Silent Spring documenting the impacts of pesticides on ecology. Because of this book, Rachel Carson is often credited with reviving the environmentalist movement. Selected Rachel Carson Quotations †¢ The control of nature is a phrase conceived in arrogance, born of the Neanderthal age of biology and philosophy when it was supposed that nature exists for the convenience of man. The concepts and practices of applied entomology for the most part date from that Stone Age of science. It is our alarming misfortune that so primitive a science has armed itself with the most modem and terrible weapons and that in turning them against the insects it has also turned them against the earth. †¢ Through all these new, imaginative, and creative approaches to the problem of sharing our earth with other creatures there runs a constant theme, the awareness that we are dealing with life with living populations and all their pressures and counter pressures, their surges, and recessions. Only by taking account of such life forces and by cautiously seeking to guide them into channels favorable to ourselves can we hope to achieve a reasonable accommodation between the insect hordes and ourselves. †¢ We stand now where two roads diverge. But unlike the roads in Robert Frosts familiar poem, they are not equally fair. The road we have long been traveling is deceptively easy, a smooth superhighway on which we progress with great speed, but at its end lies disaster. The other fork of the road -- the one less traveled by -- offers our last, our only chance to reach a destination that assures the preservation of the earth. †¢ If I had influence with the good fairy who is supposed to preside over the christening of all children, I should ask that her gift to each child in the world be a sense of wonder so indestructible that it would last throughout life. †¢ For all at last returns to the sea -- to Oceanus, the ocean river, like the ever-flowing stream of time, the beginning and the end. †¢ One way to open your eyes is to ask yourself, What if I had never seen this before? What if I knew I would never see it again?† †¢ Those who dwell, as scientists or laymen, among the beauties and mysteries of the earth are never alone or weary of life. †¢ If facts are the seeds that later produce knowledge and wisdom, then the emotions and the impressions of the senses are the fertile soil in which the seeds must grow. †¢ If a child is to keep alive his inborn sense of wonder, he needs the companionship of at least one adult who can share it, rediscovering with him the joy, excitement, and mystery of the world we live in. †¢ It is a wholesome and necessary thing for us to turn again to the earth and in the contemplation of her beauties to know of wonder and humility. †¢ Only within the moment of time represented by the present century has one species -- man -- acquired significant power to alter the nature of his world. †¢ Those who contemplate the beauty of the earth find reserves of strength that will endure as long as life lasts. †¢ The more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction. †¢ No witchcraft, no enemy action had silenced the rebirth of new life in this stricken world. The people had done it themselves. †¢ Like the resource it seeks to protect, wildlife conservation must be dynamic, changing as conditions change, seeking always to become more effective. †¢ To stand at the edge of the sea, to sense the ebb and flow of the tides, to feel the breath of a mist moving over a great salt marsh, to watch the flight of shore birds that have swept up and down the surf lines of the continents for untold thousands of year, to see the running of the old eels and the young shad to the sea, is to have knowledge of things that are as nearly eternal as any earthly life can be. †¢ There is no drop of water in the ocean, not even in the deepest parts of the abyss, that does not know and respond to the mysterious forces that create the tide. †¢ The current vogue for poisons has failed utterly to take into account these most fundamental considerations. As crude a weapon as the cave mans club, the chemical barrage has been hurled against the fabric of life a fabric, on the one hand, delicate and destructible, on the other miraculously tough and resilient, and capable of striking back in unexpected ways. These extraordinary capacities of life have been ignored by the practitioners of chemical control who have brought to their task no high-minded orientation, no humility before the vast forces with which they tamper. †¢ These sprays, dusts, and aerosols are now applied almost universally to farms, gardens, forests, and homes-nonselective chemicals that have the power to kill every insect, the good and the bad, to still the song of birds and the leaping of fish in the streams, to coat the leaves with a deadly film, and to linger on in soil-all this though the intended target may be only a few weeds or insects. Can anyone believe it is possible to lay down such a barrage of poisons on the surface of the earth without making it unfit for all life? They should not be called insecticides, but biocides. Quotes About Rachel Carson †¢ Vera Norwood: In the early 1950s, when Carson finished The Sea Around Us, she was optimistic about the use science could make of nature while still respecting the final priority of natural processes over human manipulation. . . . Ten years later, at work on Silent Spring, Carson was no longer as sanguine about the ability of the environment to protect itself from human interference. She had begun to understand the destructive impact civilization had on the environment and was presented with a dilemma: the growth of civilization destroys the environment, but only through increased knowledge (a product of civilization) can destruction be stopped. John Perkins: She articulated a philosophy of how civilized people ought to relate to nature and its care. Carsons technical critique of insecticides launched from a philosophical foundation ultimately found a home in a new movement, environmentalism, in the late 1960s and 1970s. She must be regarded as one intellectual founder of the movement, even though she perhaps did not intend to do so nor did she live to see the real fruition of her work.
