PAPER ON DOCUMENTARY PRAY THE DEVIL BACK TO HELL ON PBS Essay

PAPER ON DOCUMENTARY PRAY THE DEVIL BACK TO HELL ON PBS - Essay Example The originally Christian women group knew that they have to encourage Muslim women to join their cause. Together they had forged a formidable alliance worthy of being noticed by the warring men. Leymah Gbowee played the major role in the women’s peace movement through the group she had organized known as the Women of Liberia Mass Action for Peace. She was designated as Coordinator of the group but in essence the entire movement was her brainchild. At one point during their protests, some went to the extent of calling her General Leymah and an encounter ensued for her to be arrested for obstruction of justice. Asatu Bah Kenneth played a vital role as a member of the Liberian National Police. Her position in the government made her a confidant on what is happening on the frontlines. It was upon the information she provided on April 1, 2003 that they became aware that the war had just reached its highest tension. Janet Johnson Bryant then became the next piece of the puzzle as journalist for Radio Veritas. The story became headline and the women’s movement was made known to a larger audience. The group decided to send Asatu and Etweda ‘Sugars’ to go to Sierra Leone where the rebels are to establish the group’s existence and assess the situation. The movement’s secretary, Vaiba Flome, was among the most determined and influential member of the group appealing to other women to assert their power and take it to the streets. These women were able to show how peace could be possible and that it is important for women to take an active role when they see that something is awfully going awry in society. The women made ways to ensure that they are taken seriously. They enforced pacified and innovative ways such as the sex strike to get men to listen. The women flocking the streets in their white shirt and never backing down despite being undermined by the groups showed courage and fortitude. Their determination paved the way for

Valentine And Sonet Poems Essay Example for Free

Valentine And Sonet Poems Essay Same theme different historical context: The poem, Valentine, written by Carol Ann Duffy and the Sonnet XLIII, written by Elizabeth Barret Browning are both written by women and are based on the same theme, which is describing love for someone, but they are written with different historical context. Valentine is written in quite a modern way, with some very modern references, for instance by describing love as An Onion instead of a red rose or a satin heart, these are modern references which perhaps would not have been used many years ago. Whereas Sonnet XLIII is a more traditional poem, which appears to have a more romantic theme, no one would ever have thought of comparing love to such a smelly item as an onion many years ago. The Browning poem appears to have some intense descriptions of how someone is loved, for instance, I love thee to the depth and breadth and height my soul can reach This appears to be showing intense passion and love, trying to relate it to such extremes of where a soul can reach. In Duffys poem, she talks more freely about love and is comparing love to an onion. She says, I give you an onion, its fierce kiss will stay on your lips, possessive and faithful; This shows that real love can leave its mark on your lips like how the taste of an onion does. This appears to be a really bizarre thing to compare love to, it is also a really unusual way of thinking, and I think that this shows how views and values of love have changed over the century. Over a century ago, love would have been described in more traditional ways such as quoting feelings in the poem, as Browning does, for instance she writes: I love thee to the level of every days most quiet need, by sun and candlelight The actual wording of Sonnet XLIII shows a more traditional language also by using words such as thee and phrases such as in my old griefs these words and phrases are not normally used in modern language now. STAGE ONE manner of the poem-relationships of poet to the reader The Valentine poem by Duffy appears to be a more informal and relaxed style of relaying the thoughts of love and it appears that the writer is trying to establish a more thoughtful way for the reader to think of love. By quoting something as unusual as an onion, which would not normally be associated with love in any particular way, it makes the reader really perhaps look at an onion in a different light, noticing that it does have an inner beauty, beyond the ugly brown skin, she quotes I give you an onion, it is a moon wrapped in a brown paper, and it promises light.. This is making to reference beauty being more than skin deep. The Sonnet XLIII by Browning is a much more structured poem and is more formal. It is not comparing love to a physical object; it describes the feeling of how much love the writer is feeling and also to what extent. The poet is trying to describe her innermost feelings to the reader and also trying to describe the extent of her love by using emotions, she writes I love thee freely.. and I love the purely.. and also a phrase beginning In my old griefs, these are personal feelings and not based on an object like the Valentine poem. Tone and atmosphere The Valentine poem has a most unusual tone to it. It is quirky in the sense that it uses a most unusual item to be associated with love. It is unique in itself for that same reason and for the way it breaks down the parts of an onion and relates that to how love can feel, it says Here. It will blind you with tears That is showing how strong the sensation of love can be and relating it to the power of an onion being able to make you cry. This poem does not try to be sensational in any way, but in its own right is sensational because it makes you think about something, which is so opposite to love and yet also as powerful as love in its own way. It says Its fierce kiss will stay on your lips forever This poem does not use the clichà ¯Ã‚ ¿Ã‚ ½s often associated with love and this makes the poem quite unique, when you think of a love poem many people would generally think of hearts and roses amongst many other things, but not an onion! It says, Its scent will cling to your fingers, cling to your knife This is showing the intensity of love and it can sometimes take over, being quite clingy. Brownings Sonnet on the other hand is a traditional love poem, it describes feelings to the reader, it says I love thee purely, as they turn from praise. I love thee with the passion put to use The poem appears to have a desperate need to show how deep the writers love is, it seems to try to stretch to many extremes to describe this and even wants the love to get better after death, it says, Smiles, tears of all my life and, if God choose, I shall but love thee better after death. This is a more clichà ¯Ã‚ ¿Ã‚ ½d love poem, in the sense that it uses the niceties in life to describe love, it says I love thee to the level of every days most quiet need, by sun and candlelight it is also clichà ¯Ã‚ ¿Ã‚ ½d as it uses general emotions associated with love such as smiles and tears. STAGE 2 poetic devices In Valentine, there was clever use of an onion as an extended metaphor . The onion was compared to love in many ways, it suggested that there was a moon under the brown skin of the onion, this was making the reader thinking maybe of something beautiful lying under ugly clothing. It said that the onion would blind you with tears again this was showing and relating to how powerful an onion secretly could be and that the power of love could be as strong. It said that the fierce kiss of an onion would stay on your lips, possessive and faithful, just like the power of love can be. It also said that the scent of the onion would cling to your fingers and knife, again this shows how powerful love can be and not easy to shake off once there. It said it is the moon wrapped in brown paper, it promises light like the careful undressing of love By this the writer meant that on the outside the onion appears ordinary and quite thick skinned, but as the layers of the outer skins are peeled off, bit by bit the layers get thinner and you begin to see the inner brightness and beauty of the onion, this is trying to show that inside us all there is an inner beauty no matter if the outside is a bit tatty, you sometimes just have to peel back the layers to find it that inner beauty. The imagery that she is using here is quite a romantic type, peaceful and loving. She relates to the onions layers descending in size its platinum hoops shrink to a wedding ring Again I think here she is referring to the silvery skin inside the onion and eventually finding the right layer which is comfortable as a wedding ring this is just finding the right level inside each other that we are comfortable with. In Sonnet XLIII, Browning uses imagination and emotion as her imagery. She refers to the Sun and candlelight instead of saying day and night, quite a romantic way of writing it. She states that she loves freely, purely and with passion, these are all very emotional and deep internal feelings. She states I love thee each time to make each sentence a personal one and directed independently to the reader. Browning makes references to religion by referring to her lost saints, referring to loved ones who have passed away and also she says If God choose, I shall but love thee better after death This refers to the fact that she believes in God and the powers he has and the way he can influence your life and the fact that she believes in an afterlife and that God also can influence what happens there too! I believe that her religion gives her great strength and great beliefs and encouragement and this is shown by how she writes I love thee to the depth and breadth and height my soul can reach, when feeling out of sight. For the ends of being and ideal grace I love thee to the level of every days most quiet need, by sun and candle-light There are different structures between the two poems, which reveal the different views of the poets themselves. Duffys verse has a very irregular structure for a love poem, it does have some shape and she refers to the normal things associated with love poems, but she tries to show a different side to love by comparing it to something quite absurd. I think this shows that her thoughts on love are that no one should be judged and that love should be how each individual feels it should be. Also the fact that she compares love to an onion shows that she looks at things not just on the surface, but more deeply and sees inner beauty where you would least expect it. Brownings poem on the other hand is a structured poem, which would be typical of a Victorian woman. It shows a serious side to this woman and perhaps reflects the strict idealistic way of Victorian times. It is very thoughtful and deep and emotional which perhaps shows that this woman is a romantic in the true sense that she values the idealistic way that a relationship should be.

Analysis of statement that “acquiring foreign companies creates shareholder wealth and helps reduce many risks” Essay

The above statement discusses risk reduction as a benefit of acquisitions.   I will split the statement into two parts; one that discusses the reduction of risks through acquisitions, and the other which explains the creation of shareholder wealth through acquisitions.   The first part of this statement can be explained through the various forms of risk that are reduced due to acquisitions.   One major risk that is reduced through acquisitions is the risk from competitors, through acquiring a fair market share.   It is difficult for firms which invest through greenfield strategies to attract clients from the existing competitors. This is because a new firm has to prove its performance to clients before it can successfully attract clients from the present competitors.   This is a move that takes time, since the clients have to analyze the products of new firms before the firm can gain the necessary goodwill to attract new clients.   However, acquisitions enable firms to use the goodwill of the firm that has been acquired to retain the existing clients or share of the market.   The market associates the new firm, in this case TPS Connection Plc, with the brand name of the firm that has been acquired, and if it had favorable goodwill, the new firm will have less problems in retaining the existing clients, as well as attracting new clients from the competitors. An example of a firm that has undergone a successful acquisition process and enjoyed this benefit is Tata Steel of India, which acquired Corus of Netherlands.   Before sealing of this deal, Tata Steel Company had to undergo a long and costly process of bidding, which was estimated to cost about $13.7 billion.   However, this process paid off after Tata steel benefited from among other things, the market share of Corus Company.   In fact, after the acquisition, Tata steel moved from being the fifty-sixth producer of steel globally, to the fifth position (ICFAI Center for Management Research 2007: 8). The second risk that is reduced through acquisitions relates to the distribution channels.   A new firm has to create new distribution channels that are effective enough to gain a share of the market.   This is challenging since the present competitors already use the best distribution channels available.   A new firm faces the risk of reduction of sales due to inferior distribution channels.   However, acquisitions enable new firms to make use of the already existing distribution channels of the firm that has been acquired.   This enables the new firm, in this case, TPS Connection Plc to penetrate the market more easily through the use of the existing distribution channels of the firm that has been acquired.   The Tata Steel acquisition that has been discussed above benefited Tata from Corus’ European distribution channels, and this is among the factors that made it gain a large share of the market. The third risk that can be reduced through acquisitions relates to the costs of market research.   A new company has to effectively study the market it is penetrating so that it can have full information on the products to manufacture, the pricing system, modes of advertising among other qualities of the market.   This is an expensive process, and if not done efficiently, it might lead to the inability of a new firm to penetrate the existing market. Due to the high nature of the costs, this might be inhibiting to firms which do not have the necessary resources and technology.   However, in cases of acquisitions, for instance by TPS Connection Plc, the company that is being acquired already has valuable information on the market segmentation and trends.   It therefore becomes relatively easier for TPS company to penetrate the market using the available information from the acquired company.   It is important to note that nonetheless, TPS has to do research on its own, but this will be less difficult and will consume lesser funds as compared to a scenario where it was implementing a greenfield investment.   Another risk that is reduced is the systematic risk that may occur in certain parts of the world, or certain markets.   For instance, there is currently conflict that is going on between Palestine and Israel.   The largest brunt of the war is felt by Palestine, and it can be said that firms in this country are facing a systematic risk.   Firms in this country with interests in foreign countries can be said to have reduced their risk through diversification.   They can rely on the profits from the foreign firms in a period like this, when their profits are prone to decreasing.   This is one risk that an acquisition reduces, and TPS Connection Plc should use an acquisition as a form of entering the Chinese and Indian markets in order to reduce the systematic risk through diversification. Creation of wealth through acquisitions. There are several companies that have undertaken acquisitions which have proved to reduce risks and improve the wealth of shareholders.   Hindalco is one such company, and it acquired Novelis Inc, which is a company that deals with aluminum and is based in Canada.   Since both companies had a large market presence, the combination of resources, distribution channels, goodwill and market share ensured that Hindalco built a very strong market presence.   This presence is felt in almost all continents of the world. Creation of shareholder wealth is achieved through the following benefits of acquisitions.   The first benefit is greater value generation, and this means that a company that undertakes an acquisition or merger is likely to achieve higher value as compared to both individual firms.   This is explained by the fact that a company that undertakes an acquisition is more likely to generate a higher shareholder value that is much larger than the total number of shares of the individual companies. Another benefit that arises from acquisitions and which is likely to increase the wealth of shareholders is the gains in market share.   This benefit can be well illustrated when a firm is facing challenges in the market.   In such a scenario, an acquisition especially by another firm which has a strong presence in the market, is likely to make the weaker firm experience greater levels of cost efficiency and competitiveness.   In this case, there are two beneficiaries to the acquisition; the weak company benefits from elimination of its market problems, while the joint company benefits from a larger share of the market. A third benefit of an acquisition which is consistent with the wealth creation goal of a company is the cost efficiency gain.   This benefit is realized through economies of scale benefits that are realized from acquisitions and mergers.   Such benefits include ease of raising capital, sharing of resources by both firms, advancement of discounts from bulk purchases among other benefits.   Other benefits include increase in production due to the acquisition, which then leads to the reduction of the production costs of individual units.   Increase in efficiency can also be achieved through sharing of technology.   In the Hindalco acquisition, this firm gained very useful technology from Novelis Inc., which some experts estimate would have taken a decade to develop. The fourth benefit that can be attributed to the acquisitions and mergers is the reduction in the administration costs.   This occurs due to the sharing of established resources between the two firms.   For instance, when a firm enters a new market through an acquisition, it does not spend much funds setting up the different departments that are needed for operations.   Instead, a firm will use the existing departments of the new firm that is being acquired. A fifth benefit of an acquisition which TPS Connection Plc would enjoy is the increase in global presence.   When this firm acquires a company which has a strong brand name, its presence will be felt in the market, which would attract more clients to the company.   When Hindalco, an India based company acquired Novelis, a large Canada based aluminum company, this increased the global presence of the former (ICFAI Center for Management Research 2007: 6).   This was achieved through combining the strengths of the two companies and their distribution network, thereby ensuring that it had a presence in almost all continents of the world.   All these benefits either help to increase revenue or decrease costs, which is consistent with the goal of a company of increasing the wealth of the shareholders. Assessment of the decision to invest using FDI. The decision to invest in these countries using FDI is borne out of the benefits that are present in this form of investment.   This decision arises out of many factors that are present in the countries where these companies seek to invest.   For instance, when TPS Connections Plc is assessing the type of investment to undertake when penetrating the Chinese and Indian markets, it will be guided by some factors.   Some of these factors include the macroeconomic conditions of these markets, such as the benefits that foreign investors gain.   Other factors include the nature of the competition and the available forms of financing.   However, in totality, some of the main factors that make FDI a favorable form of investment are discussed below; The first reason originates from the fact that nation states usually encourage FDI in their countries.   This is due to several benefits that such states reap from the FDI.   One benefit includes the increase in revenue for the host country.   In any country, economic growth is increased through investments.   This increases the purchasing power of residents of the country due to the increase of incomes attributable to economic growth.   The increase in purchasing power leads to the increase in demand for services and goods produced within the country, and this also increases revenue for the government.   The government increases revenue due to the tax paid from the products as well as consumer spending and wages. The second benefit attributable to FDI in the host country is the increase of capital available for investment.   This especially useful to Least Developed Countries which do not have sufficient capital to invest in large projects.   FDI also helps local investors to acquire the currency needed for the purchase of investment resources.   These benefits create export opportunities thereby increasing the total capital that is available for local investment. Another reason that makes host countries encourage FDI is the increased employment opportunities that are associated with this type of investment.   Worldwide, multinationals employ over 55 million people directly, and another 10 million indirectly.   Greenfield foreign investments create the most employment opportunities, especially the creation of new industries.   However, acquisitions and mergers have been known to cause redundancies due to reduction or retraining of employees.   FDI can also lead to reduction of employment levels if weak local industries are forced to shutdown due to competition from foreign players. A third reason which leads to encouragement of FDI by countries is the introduction of technology and new skills.   Most multinationals invest in other countries due to the superior technology that they possess, which makes their products more competitive than those of their competitors.   This is achieved through increased efficiency and quality of products due to technology.   This benefits the host country by making its products more competitive in the global market. Finally, there are other spillover effects that benefit the host country, and some of them include linkages between local firms and multinationals.   Competition between local firms and multinationals enables the local industries to produce higher quality products.   Since the foreign firms export some of the products that are produced to home countries, the host country benefits from foreign exchange.   FDI also encourages the development of infrastructure either by the government or by the investors, which is a long term benefit to the host country. All these are reasons which make countries encourage FDI.   When TPS Connections Plc is entering the Chinese and Indian markets, the two countries are likely to encourage FDI for similar reasons.   They already have laws that encourage FDI and an infrastructure that supports the same.   For instance, the Chinese labor laws keep the cost of labor cheap, thereby encouraging investment by Hong Kong multinationals.   Other benefits include the strong economic growth and open door policies that seek to attract foreign investors.   These are benefits that TPS Connections Plc seeks to gain from. It is therefore beneficial for TPS Connections Plc to enter these markets and enjoy a favorable macroeconomic environment.   This will ensure that costs are reduced and sales maximized in order to boost profits. Another reason why TPS Connections Plc should undertake FDI in its entry to the Chinese and Indian markets is to tap the existing potential in the two markets.   China is the largest country in the world in terms of population, and this shows that there is a huge potential in terms of the market size (Easson 2004: 23).   As previously discussed, its macroeconomic environment favors FDI, a fact which leads to half of the exports in China being attributed to FDI by firms.   The large market size when combined with the favorable macroeconomic environment highly favors the success of foreign investors who invest in these two countries.   TPS Connection Plc should therefore take advantage of this factor to invest in these countries through FDI. Labor is also relatively cheap in both of these countries and FDI would enable both countries to reduce the cost of production, which would ultimately increase efficiency and hence profitability.   This strategy is consistent with the comparative advantage theory which states that companies should specialize in what they can easily produce better than their competitors. In this case, access to cheaper labor would have be beneficial to TPS Connections Plc, since it would reduce costs, and make its products cheaper than those of its competitors. One multinational that has effectively used this strategy is the Unilever Company.   This company has branches in different parts of the world, due to the need of having access to raw materials as well as cheap labor.   This company has concentrated its labor intensive operations in Asian countries due to the availability of cheap labor, especially from countries such as India.   This has enabled this company have an edge over its competitors, and it is currently among the biggest global producers of foodstuffs and household products. In assessment of the above factors, I would highly recommend the entry of TPS Connections Plc to the Indian and Chinese markets through FDI, since this will be beneficial not only to TPS Connections Plc, but also to the Chinese and Indian economies.   Since this move is beneficial to both the economies, these two countries are likely to make the entry process faster and relatively easier, as compared to the situation that would have been present if the entry would adversely affect the economy of the two countries.   This would also enable this company to reap the benefits of globalization through the transfer of technology from the parent company to its subsidiaries and vice verse.

Contributions of Carbon Dioxide Removal as Geoengineering Solution to Climate Change

Contributions of Carbon Dioxide Removal as Geoengineering Solution to Climate Change Abstraction Climate Change I will hold an overview and a speedy treatment on clime alteration as an debut for the paper. Geoengineering Technologies When it comes to environmental direction you can non acquire any longer banal today than a focal point on clime alteration, nevertheless, I wish to undertake this subject in a alone manner. While I plan on discoursing green engineering and C caps, the chief focal point of my paper will be on clime technology besides known as geoengineering. Geoengineering, in my sentiment, is frequently a forbidden subject as many see human accommodation of the natural order to be avoided at all cost. I feel this to be a subset of the realistic false belief. The fact of the affair is that if worlds expect to stabilise the clime, they need to take a more active function on it. Geongineering engineerings chief end is Geoengineering engineerings fall under two classs: ( 1 ) Carbon Dioxide Removal ( CDR ) which â€Å" reference warming effects of nursery gases by taking C dioxide from the ambiance † ; and ( 2 ) Solar Radiation Management ( SRM ) which, on the other manus, â€Å" address clime alteration by increasing the coefficient of reflection of the Earth ‘s ambiance or surface† ( Bracmort, K. , & A ; Lattanzio, R.K. , 2013 ) . Such illustrations of CDR are carbon gaining control and segregation ( CCS ) , ocean fertilisation, enhanced weathering, and afforestation while illustrations of SRM are aerosol injection and space-based reflectors. While SRM methods purpose to cut down sunshine being absorbed by our ambiance, CDR methods work to take nursery gases from the ambiance or pin down it before even making the ambiance.

Discussion The Future of Carbon Dioxide Removal Recent Developments Costss and Economic Potential Some can be done with merely a comparatively little sum of money and you can see fiscal payback†¦ The two cheapest geoengineering engineerings are afforestation and aerosols. The former is safe but it merely has limited effectiveness and will wait for at least 20 old ages to cognize its effects on clime alteration. The latter is what they call the ideal method because it is really effectual and inexpensive at the same clip. However, it can besides present unwanted side effects, therefore, has high degree of uncertainness. Environmental Risks and Restrictions Every thing has a hazard of its ain. If miscalculated, these geoengineering engineerings may present some great impact to the environment, may hold negative effects, and/or may be deemed uneffective. It may non be avoided since there are besides external factors like natural alterations, catastrophes, and even alterations in carnal behaviour. The lone inquiry is, is this the hazard we are willing to take? Decision Mentions Bracmort, K. & A ; Lattanzio, R.K. ( 2013 ) . Geoengineering: Administration and Technology Policy ( CRS Report ) .

Vector quantities such as displacement, velocity, and acceleration are involved. The study of the motion of objects under the action of forces is called dynamics. The study of the motion of objects, and the related concepts of force and energy, form the field called mechanics. Mechanics is customarily divided into two parts i. e. kinematics and dynamics. Kinematics : the description of how objects move. Kinematics in one dimension : describing an object that moves along a straight line path, which is one dimensional motion. Kinematics in two dimensions : the description of the motion of objects that move in paths in two (or three) dimensions. Dynamics : deals with force and why objects move as they do. In this part we will solve the following questions : What akes an object at rest begin to move ? What causes a body to accelerate or decelerate ? What is involved when an object moves in a circle ? We can answer in each case that a FORCE is required. 2. 1 DEFINITIONS of LINEAR MOTION Linear motion is motion along a straight line. Three types of motion: Translational Rotational Vibrational ASD 2011/12 KINEMATICS 3/23 PPH0095 MECHANICS Fig ure 1 We only discuss objects that move without rotating (Figure 1a) Motion in straight line; Vertical Horizontal Slanting Reference Frames Any measurement of position, distance or speed must be made with respect to a frame of reference. It is always important to specify the frame of reference when stating a speed. In everyday life, we usually mean with respect to the Earth. Position For one-dimensional motion, we often choose the x axis as the line along which the motion takes place. The position of an object at any moment is given by its x coordinate. If the motion is vertical, as for a dropped object, we usually use the y axis. 2. 2 DISTANCE The length of the actual path or total path length. It depends on the frame of reference, for example, Ipoh is 200 km away from Kuala Lumpur. A set of coordinate axes represents a frame of reference. ASD 2011/12 KINEMATICS 4/23 PPH0095 MECHANICS 2. 3 DISPLACEMENT The change in position of the object, i. e. displacement is how far the objects is from its starting point. For example : A change from an initial position xi to the final position xf, the displacement is, ? x = xf xi. The symbol ? (delta) means change in. So ? x means the change in x which is the displacement. It is a quantity that has both magnitude and direction and represented in diagrams by arrows. Example 1 : A person walking 70 m to the east and then turning around and walking back (west) a distance of 30 m. Total distance = 100 m Displacement = xf xi = 40 m 0 m = 40 m Figure 2 2. 4 SPEED and VELOCITY The most obvious aspect of the motion of a moving object is how fast it is moving, i. e. its speed or velocity. Speed is simply a positive number, (i. e. a scalar: having magnitude only) with units. Velocity, on the other hand, is used to signify both the magnitude (numerical value) of how fast an object is moving and also the direction in which it is moving. (velocity is therefore a vector). Average Speed is defined as the total distance travelled along its path divided by the time it takes to travel this distance, i. . average speed = distance travelled time elapsed ASD 2011/12 KINEMATICS 5/23 PPH0095 MECHANICS 2. 5 AVERAGE VELOCITY Average velocity is defined as the displacement divided by the elapsed time, i. e. average velocity, v ave = x f xi displacement ? x = = time elapsed ? t t f ti Average velocity would be zero if starting and ending point are the same. Unit : ms-1 Fi gure 3: Velocity of a car as a function of time at constant velocity. Figure 4: Velocity of a car as a function of time with varying velocity. 2. 6 INSTANTANEOUS VELOCITY The instantaneous velocity is the velocity at any instant of time. In general the instantaneous velocity at any moment is defined as the average velocity over an infinitesimally short time interval. We define instantaneous velocity as the average velocity in the limit of ? t becoming extremely small, approaching zero. v = lim ?t > 0 ?x dx = ? t dt Let ? t approach zero, ? x approaches zero as well. But the ratio ? x/? t approaches some definite value, which is the instantaneous velocity at a given instant. KINEMATICS 6/23 ASD 2011/12 PPH0095 MECHANICS 2. 7 AVERAGE ACCELERATION Acceleration specifies how rapidly the velocity of an object is changing. Average acceleration is defined as the change in velocity divided by the time taken to make this change, i. e. v f vi change of velocity ? v average acceleration, aave = = = time elapsed ? t t f ti Unit : ms-2 2. 8 INSTANTANEOUS ACCELERATION The instantaneous , a , is defined as the limiting value of the average acceleration as we let ? t approach zero. instantaneous acceleration, a = lim ? dx ? d? ? 2 dv ? dt ? = d x a = = dt dt dt 2 ?t > 0 ? v dv = ? t dt since v = dx , so dt Acceleration tells us how fast the velocity changes, whereas velocity tells us how fast the position changes. x v= dt and dv d 2 x a = = dt dt 2 2. 9 EQUATIONS of LINEAR MOTIONS Many practical situations occur in which the acceleration is constant, i. e. the acceleration doesnt change over time. We now treat this situation when the magnitude of the acceleration, a, is constant and the motion is in a straight line. In this case, the instantaneous and average acceleration are equal. To simplify our notatio n, let us take the initial time in any discussion to be zero the elapsed time, t initial velocity , vo the position at time t is s the velocity at time t is v ASD 2011/12 KINEMATICS 7/23 PPH0095 MECHANICS The acceleration, which is assumed constant in time , will be a = Multiply both sides by t and get: ? v = vo + at at = v ? vo v ? vo t †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.

Figure 5a o Constant velocity Velocity = gradient of the graph = constant ASD 2011/12 KINEMATICS 10/23 PPH0095 MECHANICS Figure 5b o Constant acceleration with initial velocity u = 0 When t = 0, gradient = 0 Gradient increases as t increases ? Velocity increases Figure 5c o Constant acceleration with initial velocity u ? 0 When t = 0, gradient ? 0 hence initial velocity ? 0 Gradient increases as t increases ? Velocity increases ASD 2011/12 KINEMATICS 11/23 PPH0095 MECHANICS Figure 5d Non-uniform acceleration When t = 0, gradient ? 0 Hence initial velocity ? 0 When t = t, gradient = 0 Hence velocity = 0 When t = t2, gradient ; 0, Hence velocity is negative. When velocity is negative, ob ject is moving in the opposite direction. Velocity–time graph or v – t graph of a body shows how the velocity of a body varies with time. Velocity, v = dx dt Displacement, s = ? v dt = area under the v – t graph.

When an object is in free fall, we assume that air resistance is negligible and that the only force acting on it is gravity. Object thrown upward/downward, will both experience the same acceleration as an object released from rest. Assuming air resistance is negligible, the rate of acceleration (g) of all objects in free fall is approximately 9. 8 m/s2. The vertical motion of a freely falling object is equivalent to motion in one dimension under constant acceleration. The equations for uniformly accelerated motion can be applied to free fall. Since the motion is vertical, y replaces x and y0 replaces x0 while g replaces the symbol a. It is arbitrary whether we choose y to be positive in the upward or downward direction; but we must be consistent about it throughout a problem’s solution. Thrown downward: a = g = +9. 80 m/s2 Thrown upward: a = g = 3: A boy on a bridge throws a stone vertically downward toward the river below with an initial velocity of 14. 7 m/s . If the stone hits the water 2. 00 s later, what is the height of the bridge above the water? Solution: Take y as positive downward Given: v0 = 14. 7 m/s , ( downward) , t = 2. 00 s and g = + 9. 8 m/s/s 1 y y o = v o t + at 2 2 = (14. )(2. 00) + (1 / 2)(9. 8)(2. 00) 2 = 29. 4 + 19. 60 y = 49. 0 m 2. 12 PROJECTILE MOTION It is the motion in two dimensions under the action of gravity only (downward) We Can study the motion of a projectile by considering ASD 2011/12 KINEMATICS 18/23 PPH0095 MECHANICS o The vertical component. And o The horizontal component of the motion. The vertical component of motion is motion under uniform acceleration. The h orizontal component of motion is motion under uniform velocity If air resistance is negligible, then the horizontal component of motion does not change; thus ax = 0 and vx = vx0 = constant. The vertical component of motion is affected by gravity and is described by the equations for an object in free fall. To describe it, choose a suitable origin, O and the axes (Figure 9). Let vo denote the initial velocity and ? the angle between vo and the positive x-axis. Figure 9 From diagram, the motion can divide in two components, horizontal (x-axis) and vertical (y-axis). Two assumptions: o The free-fall acceleration, g is constant over the range of the motion and is directed downward. (-g) o The effect of air resistance is negligible that is the horizontal motion has zero acceleration. x-component 0 vxo = vocos? 0 = 0 vx x y-component -g vyo = vosin? yo = 0 vy y Acceleration Initial velocity Initial position Velocity Position ASD 2011/12 KINEMATICS 19/23 PPH0095 MECHANICS From this, one can show that: Vertical component (y-component): Vertical velocity component: v y = v yo gt = v o sin ? gt Vertical position component: 1 1 y = v yo t gt 2 = (v o sin ? )t gt 2 2 2 *from v = vo + at *from y = v o t + 1 2 at 2 At maximum Height, H, the vy = 0. 2 From, v = vo + 2a y 2 0 = (v o sin ? ) 2 ? 2 gH H= v0 sin 2 ? 2g 2 If T is the time taken from O to A, to find the T, y = 0, t = T From, y = v o t + 1 2 at 2 1 gT 2 2 0 = (v o sin ?

Horizontal position component : x = vxot = (vo cos ? )t To find the horizontal Range, R, t = T, x = R ASD 2011/12 KINEMATICS 20/23 PPH0095 MECHANICS From x = vo t + 1 2 at ,a =0 2 ? 2v sin ? ? ? R = (v o cos ? )? o ? ? g ? ? R= v o sin 2? g The maximum horizontal range is achieved when ? = 45o. At any time the distance, r of the projectile from the origin is r = x 2 + y2 By eliminate, the trajectory (the relation between x and y) is a parabola, Vertical position component : y = (v o sin ? )t 1 2 gt 2 Horizontal position component : x = (vo cos ? ) t x t = v o cos ? ? x ? 1 ? x ? y = (vo sin ? )? ? v cos ? ? ? 2 g ? v cos ? ? ? ? ? ? o ? ? o ? g x2 = (tan ? )x ? 2 2 2vo cos ? = x tan ? ? gx 2 sec 2 ? 2 2v 2 gx 2 y = x tan ? ? 2 (1 + tan 2 ? ) 2v ASD 2011/12 KINEMATICS 21/23 PPH0095 MECHANICS Since sin 2? = sin (180o 2? ), there would be two angles of projection, ? and (90o- ? ), that would achieve a particular range R for a certain speed of projection vo . For the speed of projection vo , however, the maximum range is obtained only when the angle of projection is 45o as shown in Figure 10. Figure 10 2. 13 UNIFORM CIRCULAR MOTION An object that moves in a circle at constant speed is said to experience uniform circular motion where the magnitude of velocity remains constant the direction of velocity continuously change Acceleration is defined as the rate of change of velocity. The rate of change of velocity depends on the change in direction as well as the change in the magnitude . Therefore, object revolving in a circle is continuously accelerating (even when the speed remains constant). An object moving in a circle of radius r with constant speed v, has an acceleration whose direction is toward the center of the circle and whose magnitude is given by the formula 2 aR = (Please refer to text book section 5. 2, pages 120, how to get this equation) v r ASD 2011/12 KINEMATICS 22/23 PPH0095 MECHANICS v1 aR aR v1 Figure 11 The acceleration vector always points toward the center of the circle. The velocity vector always points in the direction of motion (tangent to the circle or perpendicular to the radius of the circle). Circular motion is often described in terms of the frequency f as so many revolutions per second. The period T of an object revolving in a circle is the time required for one complete revolution.

How to Start a Book Discussion Club

How to Start a Book Discussion Club A book club is a great way to meet new friends and read good books. This step-by-step  guide will help you start a book club that can last for years. How to Start a Book Discussion Group Get together a core group - It is much easier to start a book club with two or three people who already have some connection. Ask around the office, playgroups, your church, or civic organizations. Sometimes you might find enough people to start a book club right away. Often youll at least recruit some help in completing the rest of the steps.  Set a regular meeting time - An ideal size for a book club is eight to 11 people. As you can imagine, it is often difficult to coordinate that many peoples  schedules. Go ahead and set a regular meeting time and date for your book club with your core group. For instance, meet the second Tuesday of the month at 6:30 p.m. By setting the time before advertising the book club, you avoid playing favorites when working around schedules and you are upfront about what commitment is required.Advertise your book club - The best advertising is often word of mouth. If your core group doesnt know of other people to ask, then advertise in your circles of interest (school, work, church) with fliers or announcements.   Establish ground rules - Get together with your potential book club members and set the groups ground rules. You might want everyones input. However, if you have set ideas of what you want, then set the rules with your core group and announce them at this first meeting. The ground rules should include how books are chosen, who hosts, who leads discussions and what kind of commitment is expected.Meet - Set a schedule for the first few months and start meeting. If the book club is small at first, dont worry about it. Invite people as you go. Some people will be more likely to join an already established book club because they feel less pressure than they would as a founding member.Keep meeting and inviting people - Even if your book club is an ideal size, from time to time youll have the chance to invite new people as other members move away or drop out. Hopefully, youll always have a core group, and together you can reload. Example Ground Rules for Book Clubs Hosting Duties: You may decide to rotate hosting duties. The host may select the book, lead the discussion, and provide the meal or select the restaurant or coffee shop where you meet and perhaps provide appetizers and drinks.Food and Drink: Food is not required, but it helps the discussion roll and makes the book club meetings more fun. Some book clubs meet at a different restaurant each month. Sometimes meetings are held in peoples homes. (Check out this sample book club schedule  for some suggestions). How to Choose Books Some groups vote on what books they are going to read at the beginning of the year. Others let the host for the month choose. You can also use the bestsellers lists or a national book club such as Oprahs Book Club  as a guide. No matter how your book club chooses books, you also need to decide if there will be any restrictions on the choices (ie, just fiction, paperbacks, etc.).   You may want to base choices on whether they are available at the library or have a long waiting list, and whether they are available in electronic format or audiobook format. Leading the Discussion Be prepared with discussion questions. You can search for these online for most bestsellers. Even if youre shy about leading, a few creative pointers can get the ball rolling.

Biography of Mao Zedong, Father of Modern China

Biography of Mao Zedong, Father of Modern China Mao Zedong (Dec. 26, 1893–Sept. 9, 1976), the father of modern China, is not only remembered for his impact on Chinese society and culture but for his global influence, including on political revolutionaries in the United States and the Western world in the 1960s and 1970s.  He is widely considered one of the most prominent communist theoreticians. He was also known as a great poet. Fast Facts: Mao Zedong Known For: Founding father  of the  Peoples Republic of China, ruling the country as Chairman of the Communist Party of China  from 1949 until 1976Also Known As: Mao Tse Tung, Mao Zedong, Chairman MaoBorn: Dec. 26, 1893 in Shaoshan, Hunan Province, ChinaParents: Mao Yichang, Wen QimeiDied: Sept. 9, 1976  in Beijing,  Peoples Republic of ChinaPublished Works: The Warlords Clash (poem, 1929), The Tasks of the Communist Party in the Period of Resistance to Japan (1937), Maos Little Red Book (1964–1976)Spouse(s): Luo Yixiu, Yang Kaihui, He Zizhen, Jiang QingChildren: Mao Anying, Mao Anqing, Mao Anlong, Yang Yuehua, Li Min, Li NaNotable Quote: Politics is war without bloodshed while war is politics with bloodshed. Early Life On Dec. 26, 1893, a son was born to the Mao family, wealthy farmers in Shaoshan, Hunan Province, China. They named the boy Mao Zedong. The child studied Confucian classics at the village school for five years  but left at the age of 13 to help out full-time on the farm. Rebellious and probably spoiled, young Mao had been expelled from several schools and even ran away from home for several days. In 1907, Maos father arranged a marriage for his 14-year-old son. Mao refused to acknowledge his 20-year-old bride, even after she moved into the family home. Education and Introduction to Marxism Mao moved to Changsha, the capital of Hunan Province, to continue his education. He spent six months in 1911 and 1912 as a soldier in the barracks at Changsha, during the revolution that overthrew the Qing Dynasty. Mao called for Sun Yatsen to be president and cut off his long braid of hair (queue), a sign of anti-Manchu revolt. Between 1913 and 1918, Mao studied at the Teachers Training School, where he began to embrace ever more revolutionary ideas. He was fascinated by the 1917 Russian Revolution, and by the 4th century BCE Chinese philosophy called Legalism. After graduation, Mao followed his professor Yang Changji to Beijing, where he took a job at the Beijing University library. His supervisor, Li Dazhao, was a co-founder of the Chinese Communist Party and greatly influenced Maos developing revolutionary ideas. Gathering Power In 1920 Mao married Yang Kaihui, the daughter of his professor, despite his earlier marriage. He read a translation of The Communist Manifesto that year  and became a committed Marxist. Six years later, the Nationalist Party, or Kuomintang, under Chiang Kai-shek massacred at least 5,000 communists in Shanghai. This was the start of Chinas Civil War. That fall, Mao led the Autumn Harvest Uprising in Changsha against the Kuomintang (KMT). The KMT crushed Maos peasant army, killing 90% of them and forcing the survivors out into the countryside, where they rallied more peasants to their cause. In June  1928, the KMT took Beijing and was recognized as the official government of China by foreign powers. Mao and the Communists continued to set up peasant Soviets in the southern Hunan and Jiangxi Provinces, however. He was laying the foundations of Maoism. The Chinese Civil War A local warlord in Changsha captured Maos wife, Yang Kaihui, and one of their sons in October 1930. She refused to denounce communism, so the warlord had her beheaded in front of her 8-year-old son. Mao had married a third wife, He Zizhen, in May of that year. In 1931, Mao was elected chairman of the Soviet Republic of China, in Jiangxi Province. Mao ordered a reign of terror against landlords; perhaps more than 200,000 were tortured and killed. His Red Army, made up mostly of poorly armed but fanatical peasants, numbered 45,000. Under increasing KMT pressure, Mao was demoted from his leadership role. Chiang Kai-sheks troops surrounded the Red Army in the mountains of Jiangxi, forcing them to make a desperate escape in 1934. The Long March and Japanese Occupation About 85,000 Red Army troops and followers retreated from Jiangxi  and started walking the 6,000-kilometer arc to the northern province of Shaanxi. Beset by freezing weather, dangerous mountain paths, unbridged rivers, and attacks by warlords and the KMT, only 7,000 of the communists made it to Shaanxi in 1936. This Long March cemented Mao Zedongs position as leader of the Chinese communists. He was able to rally the troops despite their dire situation. In 1937, Japan invaded China. The Chinese Communists and the KMT halted their civil war to meet this new threat, which lasted through Japans 1945 defeat in World War II. Japan captured Beijing and the Chinese coast, but never occupied the interior. Both of Chinas armies fought on; the communists guerrilla tactics were particularly effective. Meanwhile, in 1938, Mao divorced He Zizhen and married the actress Jiang Qing, later known as Madame Mao. Civil War Resumes and the Founding of the PRC Even as he led the fight against the Japanese, Mao was planning to seize power from his erstwhile allies, the KMT. Mao codified his ideas in a number of pamphlets, including On Guerrilla Warfare and On Protracted War. In 1944, the United States sent the Dixie Mission to meet Mao and the communists; the Americans found the communists better organized and less corrupt than the KMT, which had been receiving western support. After World War II ended, the Chinese armies started to fight again in earnest. The turning point was the 1948 Siege of Changchun, in which the Red Army, now called the Peoples Liberation Army (PLA), defeated the Kuomintangs army in Changchun, Jilin Province. By October 1, 1949, Mao felt confident enough to declare the establishment of the Peoples Republic of China. On December 10, the PLA besieged the final KMT stronghold at Chengdu, Sichuan. On that day, Chiang Kai-shek and other KMT officials fled the mainland for Taiwan. Five Year Plan and the Great Leap Forward From his new home next to the Forbidden City, Mao directed radical reforms in China. Landlords were executed, perhaps as many as 2-5 million across the country, and their land was redistributed to poor peasants. Maos Campaign to Suppress Counterrevolutionaries claimed at least 800,000 additional lives, mostly former KMT members, intellectuals, and businessmen. In the Three-Anti/Five-Anti Campaigns of 1951-52, Mao directed the targeting of wealthy people and suspected capitalists, who were subjected to public struggle sessions. Many who survived the initial beatings and humiliation later committed suicide. Between 1953 and 1958, Mao launched the First Five-Year Plan, intending to make China an industrial power. Buoyed by his initial success, Chairman Mao launched the Second Five-Year Plan, called the Great Leap Forward, in January 1958. He urged farmers to smelt iron in their yards, rather than tending the crops. The results were disastrous; an estimated 30-40 million Chinese starved in the Great Famine of 1958-60. Foreign Policies Shortly after Mao took power in China, he sent the Peoples Volunteer Army into the Korean War to fight alongside the North Koreans against the South Koreans and United Nations forces. The PVA saved Kim Il-Sungs army from being overrun, resulting in a stalemate that continues to this day. In 1951, Mao also sent the PLA into Tibet to liberate it from the Dalai Lamas rule. By 1959, Chinas relationship with the Soviet Union had deteriorated markedly. The two communist powers disagreed on the wisdom of the Great Leap Forward, Chinas nuclear ambitions, and the brewing Sino-Indian War (1962). By 1962, China and the USSR had cut off relations with one another in the Sino-Soviet Split. Fall From Grace In January 1962, the Chinese Communist Party (CCP) held a Conference of the Seven Thousand in Beijing. Conference chair Liu Shaoqi harshly criticized the Great Leap Forward, and by implication, Mao Zedong. Mao was pushed aside within the internal power structure of the CCP; moderate pragmatists Liu and Deng Xiaoping freed the peasants from communes and imported wheat from Australia and Canada to feed the famine survivors. For several years, Mao served only as a figurehead in the Chinese government. He spent that time plotting a return to power and revenge on Liu and Deng. Mao would use the specter of capitalist tendencies among the powerful, as well as the might and credulity of young people, to take power once again. The Cultural Revolution In August 1966, the 73-year-old Mao made a speech at the Plenum of the Communist Central Committee. He called for the youth of the country to take back the revolution from the rightists. These young Red Guards would do the dirty work in Maos Cultural Revolution, destroying the Four Olds- old customs, old culture, old habits, and old ideas. Even a tea-room owner like President Hu Jintaos father could be targeted as a capitalist. While the nations students were busily destroying ancient artwork and texts, burning temples and beating intellectuals to death, Mao managed to purge both Liu Shaoqi and Deng Xiaoping from the partys leadership. Liu died under horrific circumstances in prison; Deng was exiled to work in a rural tractor factory, and his son was thrown from a fourth-story window and paralyzed by Red Guards. In 1969, Mao declared the Cultural Revolution complete, although it continued through his death in 1976. Later phases were directed by Jiang Qing (Madame Mao) and her cronies, known as the Gang of Four. Failing Health and Death Throughout the 1970s, Maos health steadily deteriorated. He may have been suffering from Parkinsons disease or ALS (Lou Gehrigs disease), in addition to heart and lung trouble brought on by a lifetime of smoking. By July 1976 when the country was in crisis due to the Great Tangshan Earthquake, the 82-year-old Mao was confined to a hospital bed in Beijing. He suffered two major heart attacks early in September, and died September 9, 1976, after being removed from life support. Legacy After Maos death, the moderate pragmatist branch of the Chinese Communist Party took power and ousted the leftist revolutionaries. Deng Xiaoping, now thoroughly rehabilitated, led the country toward an economic policy of capitalist-style growth and export wealth. Madame Mao and the other Gang of Four members were arrested and tried, essentially for all of the crimes associated with the Cultural Revolution. Maos legacy today is a complicated one. He is known as the Founding Father of Modern China, and serves to inspire 21st-century rebellions like the Nepali and Indian Maoist movements. On the other hand, his leadership caused more deaths among his own people than that of Joseph Stalin or Adolph Hitler. Within the Chinese Communist Party under Deng, Mao was declared to be 70% correct in his policies. However, Deng also said that the Great Famine was 30% natural disaster, 70% human error. Nonetheless, Mao Thought continues to guide policies to this day. Sources Clements, Jonathan. Mao Zedong: Life and Times, London: Haus Publishing, 2006.Short, Philip.

The Effects of Overfishing on Oceans Essay Example | Topics and Well Written Essays - 1250 words

The Effects of Overfishing on Oceans - Essay Example Integrated approach in coastal and ocean resources management must be applied. The tranquility of the sea was at late 1967 and was unhurriedly being disrupted by technological interventions, accelerating and multiplying uses, and a dynamic rivalry which poised to cross the threshold of man's precious seabed (United Nations, 1998). At that time, both dangers and promises were upheld while the dangers were abundant: nuclear submarines charting or documenting deep waters which were never before explored. Supertankers ferrying oil starting Middle East to European going to other ports, then, they pass along congested straits and leaving at the rear tracking of oil spills. These resulted to the rising tensions between nations greater than conflicting claims to ocean regions and resources. Levenson in 1996 stated that ( p 100, par 2), marine resources are severely affected by a broad range of natural as well as human perturbations, such as pollutants from human effluents. Wastes can take place directly in marine waters, although it can also indirectly be transported to the sea by rivers. Several studies can support that pollutants have originated from human activities and have resulted in an extensive diversity of impacts on water quality, marine organisms and sediment quality. Moreover, poisons or toxic chemicals introduced in coastal waters would jeopardize marine life. A toxic chemical (Seger, 2006) is a substance which can cause death or unfavorable sublethal effects in marine organisms exposed to it at certain level of concentration above a critical threshold. Many substances which are considered toxic at high levels may inhibit the life and growth of marine organisms. Anthropogenic inputs of deadly substances can be absorbs safely in the oceans but the quantity introduced does not source concentrations to go beyond the threshold at which sub lethal toxicity exists.All the more, sub lethal or lethal toxicity entry concentrations are difficult to establish because they vary among substances, among species, and with other factors, like the physical stresses, synergistic as well as antagonistic ef fects of further chemical constituents. Usually, it is the marine organisms which bioaccumulate the majority of toxic essences. Bioaccumulation occurs if and when, the concentration in the organism is elevated compare to the environmental concentration; however, the concentrations are in equilibrium. On the other hand, biomagnification takes place when the organism preserves all the toxic substance from food or environment that they have been exposed to and does not remove any of the substance. Lethal substances to marine life include carcinogens, mutagens, and teratogens and can product lethal or sublethal effects. Similarly, Joint Ocean Commission Initiative ( 2009, par 2-6) reiterated that, decline of fish products will produce impacts on fishing communities and this in turn, poses a dramatic threat to people's significant cultural heritage, source of food, income, and

IKEA Warehouse System Essay Example | Topics and Well Written Essays - 750 words

IKEA Warehouse System - Essay Example IKEA furniture are cheap, durable and stylish. Source: The Economist, 2011, http://www.economist.com/node/18229400 From the start, IKEA was perceived as the David of furniture stores who was willing to challenge the Goliaths of furniture dealers, for which reason it concentrated on developing top-quality, low-cost furniture (Elsner, W & Hanappi, 2008). On the other hand, the challenges posed by the group of competitors was much like that of a cartel. The Swedish furniture dealers pressured suppliers not to sell to independent manufacturers to create an artificial shortage of raw materials. They also excluded unaffiliated furniture makers and dealers from their trade fairs. Ingvar Kamprad, the founder of IKEA, saw social problems in the furniture industry, as well as a business opportunity. He saw that the great majority of people had needs which were not being met as far as the need for beautifully crafted but affordably priced furniture and household items were concerned. At the sam e time, he felt that this exclusion of the masses was not fair nor warranted, and that people of all walks of life are entitled to good furniture (Reichert, 1998, p. 3). ... The house is designed with architecture by IdeaBox, mostly straight lines with little detail. Source: Dornob, http://dornob.com/flat-pack-ikea-house-built-shipped-for-under-100000/?ref=search Kamprad was not a social idealist without a practical agenda. He saw a business opportunity in the fact that a huge market existed which was not being serviced by the existing manufacturers and their contract-bound suppliers and retailers. However, this market had a relatively low price target, therefore if the company intends to realize a profit out of its sales to this market segment then it should be able to maintain its production and distribution costs at a margin below the selling price (The Economist, 2011) Flat-packed IKEA furniture can be carted home at the back of a car without need for incurring delivery costs. The packaging also saved on store and warehouse space. Source: http://earth911.com/wp-content/uploads/2010/05/IKEA-Flat-Pack-300x199.jpg?84cd58 Based on this strategic directio n, the Company developed most of its product designs, supplier relationships, and customer service practices in a way that was intended to minimize production costs and maximize value for the customer. The novel idea was to produce low-cost furniture that were easy to build, and easy for the customer to assemble by himself. The principal innovation that sets IKEA apart is its flat-pack packaging that made IKEA furniture easy and cost-effective to ship, store, sell, and later set up through self-assembly. The cost savings the company realized in terms of saved store space, delivery and labour costs were passed on to the customers in terms of lower prices. In marketing, what the company essentially pioneered in is â€Å"the self-service method of selling† which, aside

Stanley Fish's Critique of John Locke's Concept of Toleration Essay

Stanley Fish's Critique of John Locke's Concept of Toleration - Essay Example Locke argues that there is no religious support for use of coercion, and thus it should not be used to bring persons to salvation. He also often cites his concerns on the level of hypocrisy, he points out that those persons who are so quick to persecute are themselves ignorant of the most grievous sins that happen around them. These transgressions represent a much greater threat eternally than do the sins that they seek to persecute. In the letter, Locke cites many more but similar religious arguments; he further proceeds to provide three reasons which he believes should provide enough grounds for preventing the state to coerce people into adopting specified religious beliefs. First, he identifies that the concern for human soul has not been bequeathed to the magistrate by either God or humans. This argument borders on the view presented in the Two Treatises to confound the natural freedom and sameness of humans. There is no authority within the Bible that requires the magistrate to commit people to the actual faith and that persons should not agree to such an idea for the state as it is impossible for human, at will, to accept as true what the magistrate identifies as true .Their faith is founded on that they consider as true and not really what they wish. Locke’s second argument holds that as the government’s power is yielded in its force, and religion is primarily about free choice founded on inward persuasion of the mind, then it follows that force cannot be used to compel people to follow religion. The third and last argument identifies that even though human’s state of mind could be altered through force, a state where all joined the magistrate’s religion would not bring additional people to the true religion. This is due to the fact that most magistrates ascribe to false religions. Locke’s view on religion and the state has been respected for a favorable period of time, it is not also uncommon to see modern person relat ing with the very elements of his thoughts. This should not be taken to mean that his argument as detailed in the Letter Concerning Toleration is flawed but it means that just like in every philosophical work owner’s prejudices find their way into the argument (Fish, 1997:2255). This is often exposed by a through look at the point’s advanced and constructive criticism of the same allowing a subsequent reader to identify the areas of weakness. Such is the case with Locke’s arguments, a number of modern thinkers have criticized his argument bringing out weaknesses that seem to weaken the argument. In the following part, this study focuses on such criticism as advanced by Stanley Fish. Fish’s criticism titled Mission impossible: Settling the just bounds between the church and the state seeks to reconcile the two, religion and state a task which appears impossible under John Locke’s restoration argument. Fish’s argument starts with Locke’ s assertion at the beginning of his letter that every church is orthodox to itself and that in a situation where there emerge conflicts between these orthodoxies there would be no one on earth able of moderating between them. In such situations Locke insists on the need for tolerance, however, the problem is that if this is allowed to regulate behavior then the role of government as a regulator of wrongful conduct would be curtailed by those who cite that their wrongful conduct is informed by their

The Collapsible Lunch Box Idea Essay Example | Topics and Well Written Essays - 2500 words

The Collapsible Lunch Box Idea - Essay Example The first idea involved whether we were capable of producing folding chairs. This idea failed due to the fact that after its assessment it was discovered that the production of folding chairs would cost too much. The second idea was the production disposable mats. This idea was quite a viable but it was ruled out after assessing that in order to reach to this final product it would involve quite a number of different processes. The feasibility of a business idea demonstrates how practical it is to put the idea into action. In line with this we had other options such as the production of a modified pub tray. The idea was a good one but we did not have information about the technical aspect of the product as how it would function. In addition the production of a modified pub tray would require too much work from sub contractors. Another feasible idea involved the production of plastic water cups. We discovered that the demand for this is too high and it would be quite difficult to prod uce enough to meet the demand. In this case consumer satisfaction is an essential aspect worth consideration if a business idea is to be adopted. Final considerations were the idea of a producing a washing machine dial or a collapsible lunch box. After adequate evaluation and comparison of the two it was seen that the market for the washing machine dial would be too small to make meaning profits. ... An American museum keeper by the name David Shayt pins this evolution to this century providing some of the examples of lunch boxes that were developed. These examples include a woven basket that had a handle and a fancy box made of wood. With the former a handkerchief would be used to warp up a meal then put inside the woven basket. The latter is believed to be used by only the rich people. These lunch boxes were but a result of increased industrialization. With the Americans working away from their homes in places such as factories it was then deemed impractical of them going home for lunch on a daily basis. This is what brought about the necessity of lunch boxes as something that would be used to protect meals and allowing for their transportation with simplicity. Various have in the past been in the manufacture of lunch boxes. Schooling children have always created a market lunch boxes with materials such as vinyl and plastic being used for this market. For the adults the most co mmon materials for their lunch boxes are metallic in nature for instance aluminium or tin. These materials are used for purpose of increasing robustness of the lunch boxes and that may last for a long time. The year is 1954 in Sudbury in the region of Ontario a miner by the name Leo May invented the aluminium lunch box. The idea of this lunch came as a result of him accidentally crushing his lunch box made of tin. History has it that the Mickey Mouse the first character lunch box made of tin was produced by Frey, Paeschke and Geuder in 1935. In the 1950 the Aladdin industries came up with a creation of the first lunch box meant for children basing their invention on Hopaong Cassidy a show on the television. This

Individual privacy vs. National Security Research Paper

Individual privacy vs. National Security - Research Paper Example These efforts by the government were aimed at enhancing national security. The mode or tactics applied by the federal government to ensure national security has raised question from the public concerning the cost the public needs to pay for a secure nation. Civil liberties are personal freedoms and guarantees that are beyond the control and regulation of the federal government. With the current anti terrorism trend, the government has been forced to draw a boundary between civil liberties and war on terrorism. The federal government should promote civil liberties and democracy despite the current security concerns. This analyzes the importance of maintaining personal privacy without compromising national security and war against terrorism. The US patriot act was introduced after the September 11, 2001 terrorist attacks. According to our research findings, the Act was introduced to unite American and prevent any future acts of terrorism (Sunstein, 2003). The Act was therefore meant to prevent terrorism by punishing terrorists across the United States and around the world. Fighting terrorism is a good thing however; the American government seems to have taken the fight to an extreme end. This is because the war on terrorists ended up on people’s doorstep making them to become victims of the war. Since the implementation of the Patriot Act, the First and Fourth Amendment were changed to heighten war on terror. This led to a compromise on people’s freedoms. Firstly, the first and Fourth amendment considered the national security as a priority. Since the implementation of the Patriot Act, the first and fourth amendments were changed to enhance national security. This implied that according to the act the authorities had the rights to vary and at sometimes compromise people’s freedom in their fight against terrorism. Personal privacy is a civil liberty; according to the constitution, the government has a duty to ensure that it protects human righ ts. The national Act was designed to fight terrorism, had little or no concern over individual privacy and civil liberties. Although fighting terrorism to ensure national security is, a good thing for the government it is costly and therefore the government needed to think otherwise. The cost that the government incurred in ensuring national stood out as an opportunity cost. The government needed to consider the opportunity cost that it suffered in ensuring national security at the expense of civil liberties. From the investigations, it was found out that the government incurred heavy costs through Loss of credibility and trust among its people. If the government considered these cost then it could have realized that enhancing civil liberties was beyond national security. Fighting terrorists is the responsibility of the government. I have no any problem with the efforts the government took to fight terrorists. Every American citizen believes that war against terrorist compromises pe ople’s democracy and should have been controlled. Democracy was established to enhance people’s freedom on their movement, speech, and personal privacy among other civil liberties. Personal privacy is a civil liberty and hence a symbol of democracy. From the investigation, it was established that the authorities had difficulties distinguishing terrorists from citizens.

Major assignment Essay Example | Topics and Well Written Essays - 2000 words

Major assignment - Essay Example These products are customized for specialized buildings. SSI is a small division company with a closed loop organizational chart. The company is headed by Charlie who is the chief executive officer. There are three salespersons, two engineers and three project manager who look after the entire bidding process. The production department includes 45 welders, four supervisor and one plant manager. The shipping department consists of 10 employees including one shipping manager. In order to assist the administration processes, the company has two secretaries and one controller (Castleberry and Tanner, 2001). Personal Selling process of the organization The company manufactures custom steel products for specialised buildings. Structural Steel is into business to business marketing. It is a commercial transaction between two or more different businesses, for example between a wholesaler and a manufacturer. B2B transactions are generally characterised by high volume of transactions, higher i nvolvement of sales and marketing team during negotiations and much high value of money involved (Katou and Budhwar, 2008). It is a complex and long process of buying and tends to be based on client-company relationship. As a result of the amount of money and time spent during transactions and negotiations, B2B features high loyalty for brands. Also, the sellers in the B2B process are required to have numerous meetings and interactions with the customers and clients during the process of negotiation. Industrial trade shows, conferences, exhibitions and online communication sites are few of the places where business to business companies interacts with both prospects and customers (Parvinen et al., 2013). In the present case employees who are directly involved in communication with the clients are the sales persons, shipping department and engineers. The major interaction with the client is however done by the sales person, as they represent the organisation. During the process of ne gotiation, the organisation may involve engineers, shipping managers and sometimes accountants, in order to make the clients clear about the various internal processes and requirements. The purchasing process in B2B marketing is riskier than in business to customer (B2C) marketing, as the transaction amount is more and entire transaction process is based on exact quantities and products (Harrison, 1998). Purchasing process in B2B involves committee meetings as decisions are driven by specifications and expert advice is required all the time. Thus in case of Structural Steel, the personal selling process involves sales person, finance department, engineering department and many times even the CEO of the company. Sales management process Sales management process involved all stages from cold calling, prospecting, negotiation to shipping of final products and billing. It includes an entire cycle where clients orders specific products or services and the company delivers it and gets the payment (Age, 2011). A sales management process is characterised by many features. It includes objectives and goals for departments, staff members and the entire organisations. These objectives and goals must be discussed with every involved and connected staff. Sales management process is a closed loop activity where performance of one department is directly related to another. Also known as sales pipeline, sales management

Qualitative Research Critique Essay Example | Topics and Well Written Essays - 1250 words

Qualitative Research Critique - Essay Example I noticed that the problem statement was quite implicit, or not stated directly in this paper, which is why I used the verb "would" and put in parenthesis the word "elder" as this was not stated directly, too. But since this is an article in a journal publication, it is understood that non-detailed information that are established clearly are an accepted norm. The Purpose of the research was clearly defined in this paper. In fact, besides the already stated Problem Statement which I have supposed as the problem and the purpose in one, there is a presented secondary purpose which was "to sensitize health care professionals and other caregivers to the chronic wound experience." The Literature Review defined and detailed "phenomenological" research as well as presented at least 13 related studies on ulcer wounds, both qualitative and quantitative in approach. There is the 2000 study of Langemo, Melland, Hanson, Olson and Hunter on eight persons with pressure ulcer, Charles (1995) study of four subjects with chronic venous leg ulcers, Walshe's 1995 study of 13 participants with venous ulcers, Chase et al's 2000 study of 21 subjects with chronic venous leg ulcer, Pieper, Szczepaniak and Templin's 2000 investigation on psy-chosocial adjustment, coping, and quality of life in persons with venous ulcers from intravenous drug abuse of undisclosed number of participants or subjects, Flanagan, Rotchell, Fletcher, and Schofield's 2001 study on a focus group of health caregivers and professionals, Krasner's 1997-98 investigation on painful venous ulcers of eight participants, Chase et al's 1997 study of seven persons with venous leg ulcers, Neil's 2000 investigation using Stigma Scale, a 24-item instrument of 150 subjects with chronic wound or serious skin problem, Neil and Munja's 2000 interview of 10 participants with chronic wounds, Ribu and Wahl's 2004 study of persons with chronic wounds, Orsted, Campbell, Keast, Coutts, and Sterling's 2001 in-depth study of several people with chronic wounds, and Hodges, Keeley, and Grier's 2001 investigation on the experience of chronic illness in older adults.

Solar cells Essay Example for Free

Solar cells Essay I am trying to find out how the current changes with the area of the solar cells. THEORY The energy in light can be transformed into electricity when shone onto semiconductor materials. Silicon and germanium normally have electrons in low energy states. Absorption of light excites these electrons into higher states and generates a voltage (typically 0. 5 V per cell). As more light is absorbed, more electrons are excited and the current supplied increases. The energy of the photons transfer to electrons in the semiconductor. The energized electrons then break free for the silicon atoms and transfer them to an electric circuit. If we completely cover the top of a solar panel then, then photons cannot get through the conductor, and the current is lost. Internal Resistance (called series resistance) if this is high then this means high losses, to minimize the losses; the cell is covered by a metallic contact grid that shortens the distance that electrons have to travel. FAIR TESTING In this experiment I will only change 1 factor, which is the area of solar cell. I would have to change the card placements which I will use to cover the solar cell at the same measurements every time. I will change the length of the card each time from 100%, 75%, 50% and 25%. The following factors that are going to be kept constant are:- 1. The distance from the lamp to the solar cell if this is changed it will affect the number of photons hitting the solar cell for each reading. 2. The positioning of the lamp if this is changed; it could also affect the number of photons hitting the solar cell for each reading. The lamps must point at the solar panel only. 3. The time this, would have to be accurate i. e. not leave the solar panel under the lamp for too long or it could affect the temperature and the intensity of the light producing photons on the solar cell. The light source The intensity of the light source will be kept the same to prevent more or less photons hitting the solar cell for each reading. 5. The bulb watt this would have to be kept constant, i. e. if I use double the watt of the bulb that double the photons will hit the solar cell. 6. The card If this is change, than this could affect the number if photons which hit the solar cell. PREDICTION Using my scientific knowledge and preliminary research I predict as the percentage area uncovered increases; more photons will hit the semi conduct device, meaning more electrons will be released resulting in more electric current.
