The purpose of this assignment is to compare stomatal densities of the upper and lower epidermis of a leaf Essay Example

The purpose of this assignment is to compare stomatal densities of the upper and lower epidermis of a leaf Essay This assignment of stomata is also relevant to my AS biology course as stomata is a key factor in transpiration of plants, and transpiration and the transport of water is a major section of the syllabus. This assignment will therefore help me to understand why transpiration occurs and how the stomata affect it as stomatas activity is related to the rate of transpiration.It is said that in general, the greater the number of stomata per unit area, the greater the rate stomatal transpiration, however distribution and densities are also important.Stomata are pores in the epidermis layer, which is found in the mesophyll spongy layer of the leaf. They are found mainly in leaves, but also in stems.There are two main functions of stomata1. To allow gaseous exchange of carbon dioxide and oxygen between the inside of a leaf and the surrounding atmosphere When the stomata are open, carbon dioxide diffuses into the sub-stomata air chambers and then into the intercellular spaces between mesophyl l cells. When it comes into contact with the wet surface of a cell it goes into solution and diffuses into the cytoplasm. Oxygen travels via the same route but the opposite way.2. To permit the escape of water vapour from the leaf this is the evaporation of water vapour from spaces in the mesophyll cells of the leaf otherwise known as transpiration.The diagram below shows a vertical section through a stoma.Each stoma is bordered with two semicircular guard cells whose movements due to changes in water content, control the size of the stomata by changes in their turgidity.If water is drawn into the guard cells by osmosis the cells expand and their turgidity is increased. . But they do not expand uniformly in all directions. The thick, inelastic inner wall makes them bend. The result is that the inner walls of the two guard cells draw apart from each other and the pore opens creating the stoma. Stomata and changes in turgidity can be seen very clearly under an electron microscope. (A diagram of stomata under an electron microscope is presented later on in the assignment)As noted before stomata activity affects the rate of transpiration, but now more specifically, it is the turgidity of stomata determines is the main cause of transpiration. It is thought that in normal circumstances when a stoma opens the turgidity of the guard cells is increased by their taking up water from the surrounding epidermal cells but it is also know that the turgidity of the stomata is also affected by external factors of the particular environment, such as light, wind, and humidity.During the day stomata tend to be open, this is because the guard cells of the stoma become flaccid to light. This is important as it allows gaseous change of carbon dioxide and oxygen to take place for photosynthesis of the plant. This can be investigated by means of a perometer, an instrument for measuring the resistance to the flow of air through a leaf. If you attach a perometer to a leaf and take meas urements of its resistance to airflow at intervals, you will find that there is a generally less resistance during daylight hours than at night. This is because the stomata open during the day and close at night.For wind, in still air, a highly saturated air shield builds up around the stoma. Air movement will sweep this layer away, which decreases the humidity of the stomata therefore increasing transpiration also a xeromorphic feature of some leaves is the presence of sunken stomata, the stomata grooves into the epidermis which then a high humidity can build up inside the stoma and reduce transpiration rates. An increase in temperature also has an effect as the guard cells become more flaccid thus increasing the capacity of the stoma therefore increasing transpiration rates.A main factor that affects the distribution and densities of stomata is the type of plant. There are two main types of plants, monocotyledonous and dicotyledonous.Monocotyledonous (monocot) or more modern lilii dae, have leaves that have parallel veins and therefore do not grow to a large size. Also their leaves are held vertically rather than horizontally, which affect where the stomata is distributed and thus the densities, leafs of a moncotylic nature therefore have equal stomatal densities on both upper and lower epidermis.Dicotyledonous (dicot) otherwise known as magnoliidae, has branched veins and therefore can grow very large leafs. Their leaves grow horizontally and as a result most or all of the stomata are found on the lower epidermis. This is because of the cuticle found on the upper epidermis. If there was no cuticle, stomata wouldnt be necessary as gaseous exchange would be much more efficient, however, then transpiration could not be controlled. This is because a waxy cuticle reduces water loss but further control is exercised by stomata. It is estimated that about 90% of the water absorbed by the roots of the plant is lost by the leaves in transpiration.An example of a monoc ot leaf is one of a maize plant. On the table below this monocot plant is compared to a dicot leaf- an oak tree leaf.Upper epidermisLower epidermisOak leaf- dicot045000Maize leaf- monocot52006800You can clearly see that the monocot leaf has similar stomatal densities and the dicot has contrasting results.The leaf I will be studying is a dicotyledonous type so based on all of my research I predict that there will be a greater number of stomata on the lower epidermis of my leaf.The plan:The aim of this investigation is to try and count the number of stomata on both sides of the leaf and then compare the results, therefore a method has to be devised to try and view the number of stomata. Viewing a leaf under a light microscope does not allow the number of stomata to be counted, as this microscope is not powerful enough. Therefore an alternative would be to get an imprint of the leaf. This can be done by painting the upper and lower leaf with clear nail varnish and then this imprint of the stomata can be seen and counted under the light microscope.FAIR TESTTo make this experiment a fair test, I will conduct the experiment on different areas on both sides of the leaf to see if this affects the density of stomata. Also four different people will count the number of stomata, so to get an unbiased number and then to calculate an average.The stomata in the field of view will only be counted, to ensure everyone is counting the same surface area. The same magnification of x 400 (high power) will be used when viewing under the microscope.The apparatus used included:- Nail varnish- A leaf- 2 glass slides and cover slips- A light microscope- TwistersMETHOD Using the eyepiece graticule.To do this, you need to have a scale (graticule) in position in your eyepiece, so that it can be seen when you look down the microscope. The scales are usually on small circular pieces of glass or acetate.1. To insert the graticule scale in your eyepiece, remove the eyepiece lens from the mic roscope and carefully unscrew the top lens.2. If you look down into the lens body, you will see a ledge running round the sides about half way down, drop the scale into the lens body so that it rests on the ledge. Then replace the lens. N.B it doesnt matter if the scale is upside down but if it annoys you then unscrew the lens again and turn the scale over.3. When you look through the microscope, you should see the scale overlying your specimen.4. To calibrate the scale, you need to use a stage micrometer. This can be a special slide with a scale engraved on it. It usually consists of a scale 1cm long, which is divided into 100 units, each of which is 0.1mm (100 um) there is an extended line every 10th unit.To calibrate the eyepiece scale1. Place the stage micrometer on the microscope stage and hold it down with the clips.2. Using the eyepiece lens with the scale in, look through the microscope and focus it so you see both scales clearly. This is usually easier if you focus your eye on the eyepiece scale and adjust the microscope so the stage comes into focus as well.3. Move the stage micrometer carefully so that the starting units of the two scales. Note down the number of divisions along each of the two scales that this represents as these represents 1 division on the eyepiece scale.4. The equation for this is:1 division on the eyepiece scale =No. Of coincided divisions X No. of divisions on the scale micrometer scaleX 10Number of divisions on the eyepiece graticule scaleAt x100 and x400 magnification the lines on the scale will have a definite thickness. It is important to measure from one side of one scale mark to the same side of the next coinciding mark.All my procedures of stomata count were done on high power therefore 1 division on the eyepiece scale = 3.5 um.When you measure another specimen, you will already have the calibration figures so all you have to do is count how many eyepiece scale divisions your specimen covers, and multiply that by the ca libration factor for tat objective lens.Method for determining stomatal density1. Apply nail varnish onto a section of the leaf2. Allow 2 minutes for nail varnish to dry and gently peel off varnish with twisters, bringing the varnish, which has an imprint of the surface of the leaf. Nail varnish was used instead of cello tape to gather an imprint because as the varnish is liquid it can mould and fill every space around the stomata on the surface, therefore creating an accurate and clear imprint to show. Cello tape might not fill every space therefore missing out stomata, which results in an incorrect perception of the stomata densities.3. Place the peeled nail varnish onto a slide with the imprint side up, add 1 drop of water and apply cover slip on top.Then the stomata are ready to be calculated.RESULTSEyepiece graticule calibration calculations.I found that 3.5 micrometers coincided with every graticule division to give 1 division of the eyepiece graticule. To calculate one divisi on on the eyepiece scale I followed to following equation:Therefore if I followed the equation:Field or areaStomata count of 4 peopleAverage117, 17, 20, 1817 + 17 + 20 + 18 / 4= 18211, 11, 11, 1211320, 19, 19, 2020Total average stomata count18, 11, 20 / 316RESULTS OF STOMATA DENSITY COUNTS.

This makes it possible to identify how likely it is that the values are significantly different or similar.The formula for the chi squared test is as follows:The ? is the Gree k O is the observed valueletter Chi. E is the expected valueThe top part of the formula for ?à ¯Ã‚ ¿Ã‚ ½ considers the size of the difference between the observed and expected values. This difference could be either positive or negative. To avoid the mathematical problems associated with negative values, the difference is squared.The bottom part of the formula relates the size of the difference to the magnitude of the number involved. The sigma ? sum symbol is required because there is not just one pair of observed and expected values but several (in this case 2)From background research, I found out that the expected values of percentage stomata densities for the upper and lower epidermis on a monocot leaf is:Upper 7%Lower 93%My observed values wereUpper 4% 499/ (total) 13268 x 100 = 3.8% to nearest integer 4%Lower 96% 12769/ 13268 x 100 = 96.2% = 96%UpperLowerE = 700O = 499E = 9300O = 12769O E = -201O E = 3469(O E) à ¯Ã‚ ¿Ã‚ ½ = 40401(O E) à ¯Ã‚ ¿Ã‚ ½ =12033961(O E) à ¯Ã‚ ¿Ã‚ ½ 40401=E 700= 57.71(O E) à ¯Ã‚ ¿Ã‚ ½ 12033961=E 9300= 1293.97? = 57.71 + 1293.97 = 1351.69?à ¯Ã‚ ¿Ã‚ ½ = 1351.69There is one more thing that needs to be added to the chi squared test, which is the degree of freedom.This relates a critical value to your chi squared values to show if there is a significant difference in the densities of stomata on the upper and lower epidermis or if it was just by chance.The degree of freedom is calculated = the number of categories minus oneIn this case it is 2 1 = 1.The critical value at one degree of freedom according to a standard calculated table of chi squared results is 3.84.If your chi ?à ¯Ã‚ ¿Ã‚ ½ value is greater than or equal to the critical value then there is a significant difference between the observed and expected values.As you can see my chi ?à ¯Ã‚ ¿Ã‚ ½ value is way above the critical value so there is a significant difference between my observed and expected values.The diagram below shows an image of stomata.From the book of where I received this image I measured the stomata to be 11 mm long. To calculate the magnification of this image youSize of image / actual size= X100DISCUSSIONThe conclusions I can gather from my results are that there is a higher percentage density of stomata on the lower epidermis and on the higher epidermis. You can see from my graphs that the lower epidermis had a density of 12769 stomata/cm2, which contained 96% of the stomata counted and the upper had a density of 499 stomata/cm2 , which contained 4% of all the stomata counted. This therefore proves my prediction correct.These results have also proved biological significance based on my research in the introduction. My results have proven that with a monocot leaf there is a higher stomata density percentage on the lower epidermis as these leaves are horizontally held and not vertically, a cuticle would have formed on the upper epidermis. This would affect the stomata density, as the main function of stomata gaseo us exchange, would be disturbed by the cuticle, so the stomata are located on the lower epidermis to prevent excessive water loss, as they have no waxy cuticle to protect them, also monocot leaves are relatively thin so the exchange of CO2 and O2 can occur relatively quickly and easily through the stomata of the lower epidermis.The sources of error in my investigation could have been:The micrometer scale took a lot of time to focus on the eye, and kept on disappearing so it was hard to take an accurate measurement of anything underneath the microscope, also the scales can be badly and easily scratched making taking accurate measurements difficult.I would perform tests on leaves of which I know the name of so I can do background research of the leaf so I can make a precise prediction of stomata densities.Different people counted the number of stomata an error could have occurred if someone did not know what stomata looked like or became subjective on if or they did not look in the s ame field of view. To try and overcome this error everyone was shown what stomata looked like before the investigation.Although magnification was kept constant someone may have adjusted it. When peeling the nail varnish, it was difficult to peel it off completely with the twisters and was a chance of mixing up slides.Another similar experiment, which could be carried out, is using cobalt thiocyanate. In the anhydrous state cobalt thiocyanate is blue, but when hydrated it turns pink. A piece of cobalt thiocyanate paper is placed on each side of a leaf and sandwiched between two glass slides clamped together, and then a stop watch is to measure the time it takes for the cobalt thiocyanate to go pink as this indicates that water has escaped out of the leaf which would be through the stomata. The time varies in which the colour change takes place depending on the temperature and humidity. Generally at room temperature the pink colour develops more rapidly on the lower epidermis of the l eaf than upper surface, the reason being there are more stomata placed on the lower epidermis.Further investigations to do with the topic are to carry out tests on a greater variation of leaves, of different shapes, sizes, thickness and leaves (maybe dicot leaves) from different habitats to see what affect this would have on the densities of stomata on a leaf.

Leave a Message What are the most important things in your life? Nowadays, whatever you are going to tell about – your life, celebrities’ private life, politics, literature or a notice of the day – may take you not more than 140 symbols, and #twitter proves it perfectly. We can more or less easily describe ourselves in 4 words, find our 3 top best features or 2 things we hate about people and choose one dream to come true†¦ Recently different funny twitter marathons became popular like #ReplaceALetterRuinATvShow or #RuinAWeddingIn5Words. They were full of creativity and fun.  IMHO such limits teach us to think and to pick catchy words from our vocabulary to express what we want and make other people pay attention to our voices, to listen to us, to follow us and, hopefully, re-tweet us. The same with the famous #elevatorpitch: imagine you were dreaming to realize the project of your life and only one person can help you, but it is so difficult to reach him or her. Suddenly you meet this person in the elevator (finally!) and you have an opportunity to attract him or her with your fabulous idea: take a chance but you have only one minute.  It reminded one story I have read once on the Internet about one professor and his stuffed jar: Practice What You Preach â€Å"The professor walks into a classroom and sets a glass jar on the table. He puts 2-inch rocks in the jar until no more can fit. He asks the class if the jar is full and they agree it is. Then, he pulls out a pile of beans, adding them to the jar, shaking it slightly until they fill the spaces between the rocks. He asks again if the jar is full, and they agree. So next, he adds a scoop of sand to the jar, filling the space between the beans and asks the question again. Then he grabs a pitcher of water and fills the jar to the brim, saying, â€Å"If this jar is your life, what does this experiment show you?†. Then he looks out at the class and says, â€Å"The rocks represent the BIG things in your life – what you will value at the end of your life – your family, your partner, your health, fulfilling your hopes and dreams. The beans are the other things in your life that give it meaning, like your job, your house, your hobbies, your friendships. The sand and water represent the ‘small stuff’ that fills our time. Can you see what would happen if I started with the sand or the beans?†Ã‚  It is very important to remember about BIG things and find proper words to leave your message to the world.   The popularity of #socialmedia makes me think of the power of a letter, the power of each word. How careful we have to be with our expressions, sayings, posts and tweets living during the time when a word is a weapon and the Internet is an information battlefield.

Foundations of Behavior Essay Example | Topics and Well Written Essays - 750 words

Foundations of Behavior - Essay Example F Skinner. The theory believes that behavioral development happens through classical and operant conditioning. There is a strong relation between stimuli and behavioral response. In this case development is seen as a continuous process where learnt responses keep accumulating and new ones increase with age. Several studies were conducted to reinforce the theory that responses in behavior are a result of external stimuli and that the external factors are more important as compared to internal factors. To take an example, John Watson experimented with an infant's responses to a rat and stimuli coupled with it. The infant was not afraid of the rat. However, he developed fear of the rat after a series of sharp sounds were made whenever the rat was shown. Behaviorists conclude that environment is more influential in shaping behavior. Also, behaviors can be modified using external stimuli. In context of psychodynamic theories, famous psychoanalyst Sigmund Freud and his theory of psychoanalysis come to mind. Psychodynamics refers to theories of Freud, his followers' or theories based on his ideas. Anna Freud, Alfred Adler Carl Jung and Erik Erickson are some of the most popular contributors from the field of psychodynamics. The theories are have been derived from sessions with patients, case studies and use of projective techniques to understand the workings of human mind. Psychodynamics strives to make connections between thoughts, motives, subconscious mind and how people perceive the world. The prime focus in psychodynamics is the interrelation between emotional states of id, ego, and superego and their impact on early developments and processes. Psychodynamics also believes that early experiences are conserved in the unconscious mind. Later in life, these conserved experiences, thoughts and emotions either remain buried in the unconscious or find way to the conscio us mind. These buried experiences are at times the cause of mental disturbances. Various psychodynamic theorists have devised their own stages of development from infancy through adulthood. However, the underlining concept is that at each stage, an individual is confronted with conflicts between biological drives and social expectations. The way to resolve these conflicts differs at each stage. Individuals constantly strive to strike a balance between personal needs and social expectations. In contrast to behaviorism school of thought, psychodynamic theory focuses on drives and forces working consciously or unconsciously within a human mind. While behaviorist theory lays stress on continuous development, psychodynamic theory believes that development happens in stages. In psychodynamics, nature and nurture both play an important role in development because the inner impulses are channeled through environmental experiences. The cognitive theory looks at humans as active participants in building knowledge. The most influential theory was propounded by Jean Piaget. According to Piaget's theory of cognitive development, children acquire 'schemes', which are the building blocks of knowledge. According to this theory, there are four stages in

Customer Service in Modern Business Assignment Example | Topics and Well Written Essays - 750 words

Customer Service in Modern Business - Assignment Example All business in any industry are able to provide the highest quality products and what the business can do to increase its competitive advantage in the market is to deliver service to the customer. It is no longer about the product because the customer can get the product from any other firm out there. Instead, the customer is looking for high-quality service and customer experience offered by the business. This applies to all types of business, whether it is a service business or a business that produces physical goods. This has come to be called customer experience and deals with all levels of service from before the customer buys the product, during the purchase and delivery of the product and the after sale service of the product. This new attitude towards the customer has also changed the way businesses are managed. For instance, in the earlier days, a floor manager would be a person with just a high school diploma. These days, even the lowest managerial jobs such as floor managers are required to be highly educated and if possible, they have to be experts in what they do. They are also paid much better and also stand to earn even more based on their productivity. Their productivity is also measured not only in terms how much sales they make but in terms of how happy the customers are. In most cases when the customers’ expectations are too high or unrealistic, it is because the customers may not necessarily understand what they want. Ironically, it is the role of the business to understand the needs of the customer in such a situation and try to expose these needs to the customer so that the customer can make an informed choice with realistic expectations. Failing to do this would lead to the customer being unhappy and always complaining about the service. The other challenge that a business may have with regard to customer expectations is when the business fails to clearly define the service capabilities. A business can avoid this kind of misunderstanding by clearly defining its capabilities and the parameters within which it is able to give its service to the customer.

African American Culture 5 Essay Example for Free

African American Culture 5 Essay Question# 4: African cultures, by and large, bring a similar world view to the relationship between man and the spiritual realm, one that is marked by an extremely personal interaction. In the broader African spiritual world human beings are seen to be under the constant influence of other people, their ancestors, minor deities, the Creator, and various forces of nature. As a result the African spiritual world can be described as interactive since all things are endowed with life-force. How is this idea expressed in ritual approaches to morality, wrongdoing, and spiritual empowerment? African American religion has always been heavily involved and influenced by the notion of morality, wrong doing and spiritual empowerment since the slave days if not earlier, African Americans came to embrace Protestant Christianity and adapted their own version of it which is consistent with evidence in the 19th century and a little bit of the 18th, at the time Christianity had little effect on slave society through the efforts of Anglicans, but it was not because African Americans rejected the gospel but because whites seized Christian brotherhood from blacks. As blacks in the South and in the British Caribbean struggled to develop individual and collective identities from the ideas and ways of African culture and their new conditions of life, the series of efforts by evangelicals to convert slaves eventually gave rise to a distinct African-American form of Christian theology, worship style, and religious community. The importance of religion and having their own take on it is among African Americans, as among all people, rests on fulfilling the human need for an understanding of one’s place in both the spiritual and temporal world. Although it was difficult, African Americans discovered in evangelical conversion requirements an opportunity to reassert personal authority based on their ability to communicate directly with God and to bring others to recognize the need for personal repentance and acceptance of Jesus. A perfect example that supports the connection between religious involvement and a sense of personal identity, is found in a slave woman who, back then it was not common for them to tell missionaries that her people have come from across the sea and lost their father and mother, and therefore want to know the Father. The displacement of Africans, for whom locality was critical to interactions with the spiritual world, did not strip them of their religious identity, but required them to learn the spiritual landscape of their new home and reshape their practices accordingly. â€Å"Come Shouting to Zion† details the many religious rituals that Africans preserved in the new world, especially those surrounding fundamental life events such as the birth and naming of children, marriage, burial ceremonies, and ritual dancing and singing to communicate with ancestors and deities. The influence of Africans with many diverse but fundamentally similar cultures in a strange new land encouraged slaves to form new pan-African cultures, which grew increasingly popular as later generations of slaves were born into bondage in America, establishing a distinct African-American culture. The pidgin African-English is a prime example of Africans in American creating a system of communication that was not traceable to a particular African ethnic origin, nor was it a perfect imitation of American English, but was instead shared by blacks in America. As slaves first encountered a foreign language that whites wished them to learn well enough to be more productive but not well enough to pose a threat to the race-based socioeconomic hierarchy, so they became acquainted with Christianity at the will of whites, but when given the opportunity, appropriated it for their own purposes. In the early encounters between slaves and Christianity it is without question that African, and particularly American-born slaves, sought a spirituality that would explain or show their temporal condition. Some salves looked to a theology of liberation and equality among Christians, which they could glean from 18th century evangelicals, mostly Anglicans, who tried to downplay these aspects of biblical teaching. The early period of evangelism was restricted by the fears of slave-owners that slaves who converted to Christianity would feel empowered to revolt against their bondage. Several conspired rebellions and many smaller incidents of black assertion were linked to blacks who had heard enough preaching to identify themselves with the enslaved nation of Israel. This fed the fears of whites, and Anglicans continued to complain that the planters who prohibited them from educating slaves on religious matters were the largest hindrance to saving African American souls. While racism was strengthened and slaves were unable to improve their social status by conforming to white European-American values, very few blacks found the Christian message Anglicans shared with them appealing . Anglican churches maintained strict separation of rich and poor, white and black, during services and sacraments. The high-church emphasized that learned men alone were authorized to teach and that blacks would listen without questioning and to accept the extension of their temporal message and isolation from whites into the religious sphere. Under these terms, it is I am not surprised that Christianity failed to take root as a meaningful religion, a spiritual world that Africans wanted to live in. But it is essential to recognize the role of whites in shaping the message that Africans were allowed to hear, and the role specifically of slaveholders in excluding blacks from access to Christianity. That blacks expressed their agency in rejecting this early version of Christianity offered to them. . At the same time Anglicans were confused over their lack of success in the Southern mainland, Moravians made a significant impact on blacks in the Caribbean by bringing a different vision of a Christian community. Moravians, Methodists, Separate Baptists, and a few other missionaries in the late 18th and early 19th centuries who sought out African Americans stressed spiritual, if not always worldly, equality. Africans identified with and embraced images of a savior who had suffered like they did, and joined these Christian images with African musical modes of expression to create spirituals that reminded: â€Å"Jesus been down to de mire/ You must bow low to de mire† (Stuckey, 139). However, you must finally accept Christianity as an affirmation of their lowly place in society and a divine exhortation to obedience and docility, as many white slaveholders had hoped they would. Rather, blacks found opportunities at biracial revival meetings which were meetings held at locations most often church, in which slaves and blacks were black would interpret what they heard and to share their divinely inspired interpretations of Christian faith, even from pulpits. During this critical period when a significant portion of blacks in the Caribbean and American South were first offered Christianity, they clearly adopted it and transformed it into something that was their own. After the period of revivals that first sparked wide-scale conversions in the South, many African-Americans focused on building a community in which they could support one another and worship in their own African-influenced style. Local black congregations extended their religious community, most notably with the founding of the African Methodist Episcopal Church in1816. As an institution spanning several states, the A. M. E. Church allowed blacks to take part at different levels in a collective, hierarchical social system as had never before been possible under American slavery. blacks continued to participate as minorities in biracial congregations (still with segregated seating) in most parts of the south and the expanding frontier, but found fewer opportunities to become ordained preachers or lay leaders in mixed parishes, where they were likely only to be allowed to â€Å"exercise the gift, provided they teach sound Doctrine sic† under the approval of whites (Frey Wood, 166). In the creation of their own religious communities in which no whites were present to criticize â€Å"overemotional† black forms of religious expression and persisting practices, such as polygamy and dancing, African-Americans actively designed a spirituality that fulfilled their needs in the slave societies of the Americas. African-American religiosity was then, as it is now, â€Å"centered on extended and expanding families and households, the importance of self-determination and personal dignity, mutual aid, and shared responsibility for the progress of the race† (Hortons, xi). In my opinion, African agency is most clearly supported by evidence of Africans defining their faith, modes of worship, and religious ties as part of a larger emerging African-American culture. Change was a relentless fact of life for Africans in 18th and 19th century America, most tragically present in enslavement and removal from Africa and domestic trade within the Americas that broke up families as masters bought and sold property. Outside the personal struggles of individual slaves, the changes in ideology and society wrought by the era of the American Revolution exposed Africans and their descendents to evolving external ideas about their place within American society, their rights as humans, and their needs as spiritual beings. Religion was one of the few arenas in which African-Americans could control the changes in their individual lives and their culture as a whole. Evolving religious traditions provided individuals over generations with a source of spiritual renewal and a supportive community and prepared an institution that could serve future generations. The long and turbulent transition from African forms of religiosity to African-influenced forms of Protestantism shows that black Americans created, out of all religious ideas and structures available to them, a faith that was their own. Question#3 The musical selections in this section come from Africa and the Americas. Some are examples of the preservation of traditional musical styles; others are examples of the adaptation of traditional modes of expression to modern styles. Prevalent in each performance is the use of either percussion instruments such as drums or singing in groups or by soloists. How do these musical selections exemplify a common African musical aesthetic, i. e. rhythmic syncopation, call-and-response, melodic constructions, vocal colors, in both traditional and contemporary expressions? African dance has contributed many characteristics to dance in America. We see evidence of this in many aspects of dance today. Being such a diverse nation, America has the blessing of combining original dances from different cultures to create an amazing dance repertoire. American dance as we know would be completely different, if it weren’t for the Africans. African dance began with the different rhythms of the tribes. Its roots in America began with the slave trade. The American slave trade began in 1619, (However, Africans were imported as slaves to the West Indies staring almost a century before that) with the arrival of Dutch trading ships carrying a cargo of Africans to Virginia. They were first brought over by boat to places such as Brazil, Cuba, and Haiti. Eventually different countries end up taking over those nations and slaves fall under their rule. In Brazil, the Portuguese take over, in Cuba the Spanish take over, and in Haiti, the French take over. The retaining of African culture by those in slavery was stronger in the other nations than in America, as the Spanish and French rulers adhered to the more lenient view of dancing taken by the Catholic Church. In America, the Protestant church strongly disapproved of dance. Therefore, dances that occurred in the West Indies, Brazil, Haiti and Cuba retained more of the African dance structure, than those in America did. Those dances can be classified as recreational or sacred. An example of a recreational dance is the Juba, which was a competitive dance where opponents would outdo each other in feats of skill, sometimes while balancing something on their head. Sacred dances were based on the worship of religious gods. The goal of the dance was for the dancer to become possessed by the god so that it would speak through the dancer. Two examples are voodoo and Shango dances. Traces of the African religious practice of possession, or disengaging from reality through the combined effects of music and dance, can be detected in the appeal of some forms of jazz dance. In America, the dance movement of Africa was restrained mainly by two factors: the attitude of the church towards dancing as being immoral and the restricted use of the primary African instrument (the drum). Drumming was banned in 1739 following a slave insurrection. White plantation owners responded by banning all drums and that forced slaves to search for other percussion options. They substituted with banjos, clapping hands, stomping feet, and the fiddle. Dances that occurred on the Plantations were for recreation and religious reasons also. Because of the European influence in America, the movement gave a distinct American appearance, rather than a strictly African one. Many dances imitated animals. There were also circle dances and dances for celebrations. Another category that emerged was competitive dances. The most well known one was the cakewalk. The slaves had witnessed their owners’ dancing festivities and imitated their stiff upper bodies while contrasting it with loose leg movements. The owners enjoyed watching this and gave a cake to the best dancer. The observation of African dancing by the whites led to them stereotyping the dancing slave. They began to blacken their faces and imitate them using such indigenous movements as the ‘shuffle’. The imitation dances by whites started an era of American entertainment based on the stereotype on the dancing ‘Negro’. Before the Civil War, professional dancers were mostly white, with the exception of William Henry Lane. He was also known as Master Juba and was a freeborn slave thought to be the best dancer in the World. He had lived in Manhattan where the Irish immigrants also lived. His dancing was a combination of Irish jig dancing and African rhythm, just like the slaves who were forced to compete with the Irish migrant workers aboard the ships. Both his movements and the Nigerian slaves are said to be the start of tap dance. Minstrelsy was also a popular form of entertainment in America from 1845 –1900. The Minstrel show was a group of male performers that portrayed the Negro as either slow and shuffling or sharply dressed and quick moving. The minstrel show proved prominent in spreading vernacular dances like the cakewalk and jig dancing on a wide scale. The next major change after minstrelsy came with the birth of ragtime music and ballroom dancing after 1910. A bunch of animal dances were seen in white ballrooms. Examples were the Turkey Trot, and Chicken Scratch. The invasion of ballrooms with native inspired dances set the stage for the same process to occur on Broadway. Zeigfield borrowed some of these dances for his Follies. Social dance became introduced on the theatrical stage. The big aspect being borrowed wasn’t the actual dances, but their swinging qualities. In 1921, Shuffle Along featured a jazz inspired dance called the Charleston. It left the audience with a lot of energy and a new respect towards black dancing. Tap was now also brought to white audiences and the musical comedies took on a new, more rhythmic life. In the late 1920s, jazz inspired songs replaced the popular white standards and America accepted Jazz music as its own. Louis Armstrong was a big part of the creation of swing music. It was a style of jazz music that emphasized African influenced rhythm and was played by big bands. Faster and sharper footwork came about and the Lindy was the new dance craze. It incorporated the shuffle and glide and buck and wing movements from early African dances. The Lindy was significant for starting jazz dance styles used in later musicals. It also gave the opportunity for white choreographers to experience African swing. Jazz music and dancing slowed down in popularity after WWII. Technology and music were evolving. The beat became more complex and musicians like Charlie Parker and Dizie Gillespie explored more with improve. The overall result was, jazz music became something more to listen to rather than to dance socially. The advent of Television in the 1950s also kept people at home instead of on the dance floors. African American dance became more of an artistic expression than a social means. Professional companies and dancers restored early African rhythms and the beauty and emotion of their traditional songs, including Catherine Dunham’s Shango, Alvin Ailey’s Revelations and Bill T. Jones’ Uncle Tom’s Cabin. In the past 50 years, African American dance has been rich in innovations as well as connections with the past. The definition of professional dance has broadened beyond ballet, modern, and jazz. Popular and social dances, including the urban black dance forms of break dancing and hip-hop have been recognized for their artistry and expressiveness. Dance created and performed by African Americans has become a permanent part of American dance. Every dancer and almost every person in America, in one way or another has danced steps that resemble early African polyrhythmic movements. Personally, I think the dance World in America could no have flourished as well as it did without it’s African influences. since the slave trade the drum has been used all over the world as a means of communication and self expression. Its broad variety of users includes the early African tribes, using them for ceremonial purposes. The Africans brought drums with them to the Americas and helped to develop their popularity among American musicians. In the mid 1900’s drum sets were brought about. These revolutionary collaborations of percussive pieces started off with a pair of hi-hats, a bass and snare drum, and a couple of tom toms. Later as the music progressed, so did the drum kits, completely eliminating the need for an entire drum section. With the coming of the rock and roll movement the drum kits were changing, they needed to accommodate the new music styles. They became sonically diverse and even electronic drums were brought about; making them infinitely adjustable both ergonomically and musically. With every major drum manufacturer competing to have the best product on the market drums will always be evolving. African American musicians and early slaves choose to use drums as a common form of expression because of the deep bass that was used to duplicate heart beat and thunder. The sound waves for open ended and string instruments is fairly straight forward. However, for a closed end instrument, such as a drum, the sound waves are different. A lot of the energy is dissipated through the shell of the drum, which is the reason for the variance in drum construction these days. Many different kinds of wood are used to generate different sounds, or a different amount of energy absorption. For a warmer, deeper sound maple construction is used while birch is used to get a high, resonant tone full of vibration. The heaviest wood that dissipates the most amount of energy is oak, creating a lower, flat sound. Question#1 I believe that Egypt’s economic progress over the last decade is a great example of showing how They have come a long way and are still vastly improving. Egypt is the third-largest economy in the Middle East and North Africa region (after Saudi Arabia and Israel), as well as one of the strongest, with significant potential for future economic growth and diversification. With a real commitment to economic reform, which favors a large privatization program and the encouragement of private investment and growth. The improvement in Ghana is evident in how their country has such a diverse economy. The Gold Coast was renamed Ghana upon independence in 1957 because of indications that present-day inhabitants descended from migrants who moved south from the ancient kingdom of Ghana. By West African standards, Ghana has a relatively diverse and rich natural resource base Mineralsprincipally gold, diamonds, manganese ore, and bauxiteare produced and exported. Exploration for oil and gas resources is ongoing. Timber and marine resources are important but declining resources. Agriculture remains a mainstay of the economy, accounting for more than one-third of GDP and about 55% of formal employment. Cash crops consist primarily of cocoa and cocoa products, which typically provide about one-third of export revenue, timber products, coconuts and other palm products, shear nuts , and coffee. Ghana also has established a successful program of nontraditional agricultural products for export including pineapples, cashews, and peppers. Cassava, yams, plantains, corn, rice, peanuts, millet, and sorghum are the basic foodstuffs. Fish, poultry, and meat also are important dietary staples. Ghanas industrial base is relatively advanced compared to many other African countries. Industries include textiles, apparel, steel (using scrap), tires, oil refining, flour milling, beverages, tobacco, simple consumer goods, and car, truck, and bus assembly. Industry, including mining, manufacturing, construction and electricity, accounts for about 25% of GDP. I strongly believe that since Ghana and Egypt have improved so vastly it is helping African Americans improve in general, the saying â€Å"We come from a long line of kings and queens is such a truthful statement if you look back on history. We have a lot of ancestry that lies within Ghana and Egypt. With the knowledge of the past it will help us to continue realize our past and bring us to terms with the future. We can reverse the process by not letting people hold us back and to not blame others. I also believe that strong knowledge of Ghana and Egypt and Mali, will also further our culture by being educated and not told how our past was. There are a lot of invention by many great African Americans that most people do not know that black inventors were behind the idea, not that is matters that a black or a white person constructed or came up with an idea for a patent, it is essential that we are have contributed just as many things if not more than any other culture. There have been so many contributions to society to western civilization and I feel it is so important that we surround our selves with knowledge of our ancestors because they worked hard to get us to the point today where we are able to vote and the possibility of a black president. The saying that we come from a long line kings and queens is so powerful because it shows you that black really is beautiful and if you retrace our ancestors you will find out that our people were just as important as kings and queens. Lewis Temple was the inventor of a whaling harpoon called the Temples Toggle and the Temples Iron. He was born in Richmond, Virginia in 1800 and arrived in New Bedford, Massachusetts in 1829. He worked as a blacksmith and had lots of friends that were whalers who bought harpoons and had lots of conversations with them. Granville T. Wood was known as the black Edison. Woods was born in Columbus, Ohio on April 23,1856. He never finished elementary school and he worked in a machine shop at a very young age. He moved to Missouri in 1872 at the age of sixteen. By 1881 he opened a factory in Cincinnati, Ohio and manufactured telephone, telegraph and electrical equipment. He filed for his first application for a patent in 1884 for an improved steam-boiler furnace. Woods patented the telographony , a combination of the telegraph and the telephone. He produced one of his most important inventions in 1887, it was called the Synchronous Multiplex Railway Telegraph. It enabled messages to be sent from moving trains and railways stations. In 1890 he set out to improve the lighting system by creating an efficient safe economical dimmer. It was safer and and resulted in 40% energy savings. Woods also created an overhead conducting system for electrical railways and the electrified third rail. By the time of his death in 1910 he had 150 patents awarded to him all together. Lewis H. L was a pioneer in the development of the electric light bulb. He was also the only black member of the Edison Pioneers, a group of inventors and scientists who worked with Thomas Edison. He was born in Chelsea, Massachusetts in 1848 and was raised in Boston. He enlisted in the Navy and served as a cabin boy on the U. S. S Massaoitta the age of sixteen. Latimer was given the assignment to draw plans for Alexander Graham Bells telephone patent . In 1879 Latimer went to work as a draftsman for Hiram Maxim, who invented the machine gun and headed the electric lighting company. Latimer worked on improving the quality of the carbon filament used in the light bulb. In 1882 he received a patent for an improved process for manufacturing carbon filaments. Gerrett is best remembered for his invention of the gas mask and the three way traffic signal. Mogan was born on March 4,1875 in Paris, Kentucky. He left school after fifth grade at the age of fourteen. He left Kentucky and headed for Cincinnati, Ohio and got a job as a handy man in a sewing shop. Morgan directed his attention to the frequent instances of firemen being overcome by fumes and thick smoke when they went into burning buildings. He perfected breathing device which he patented in 1914. In 1923morgan patented an automatic traffic signal which he sold to the General Electric Company for four thousand dollars. In 1963 Garrett A. Morgan died at ht age of 88 in Cleveland, Ohio after he was ill for two years. Just to name a few ,those were a couple of major contributors to the African American culture and western civilization.

Analysing Business Ethics And Corporate Social Responsibility Philosophy Essay

Analysing Business Ethics And Corporate Social Responsibility Philosophy Essay The question of business ethics has been at the forefront of business studies for several decades. It is an issue that has been discussed by everyone from philosophers to economists, many of whom placed an emphasis on the social responsibility of corporations and their shareholders. With the unprecedented success and profits that corporations have experienced within recent history it is no surprise that ethical problems may arise. However, is it the responsibility of corporations to help eradicate such problems even if doing so is in direct conflict with shareholder interests? This paper will explain the stakeholder and stockholder theories of corporate management and argue in favor of the stakeholder theory on the basis of the harms the shareholder argument poses in terms of both social responsibility and the stability of the corporation. In order to fully concretize its argument it will use research of Edward Freeman, Milton Friedman, and John Boatright. Stakeholder theory is one of the most well-known theories of business management. Managing for stakeholders is based on a set of relationships among groups which have a stake in the activities that make up the business. This can include but is not limited to customers, suppliers, employees, stockholders, banks, etc. Executives play an integral role in the activity of the business since they are expected to look after the health of the overall enterprise, to keep varied stakes moving in roughly the same direction, and to keep them in balance. (Freeman R. E.: 2008, Managing for Stakeholdersp.63) Freeman explains that the primary duty of the executive is to create as much value as possible for stakeholders. Where stakeholder interests clash, the executive is required to work to find solutions and bring these interests together. Executives must understand that business is fully situated in the realm of humanity. (Freeman R. E.: 2008, Managing for Stakeholdersp.64) The benefit of the stakeholder theory is that businesses, and the executives who manage them, actually do and should create value for customers, suppliers, employees, communities, and financiers (or shareholders). Edward Freeman explains in his paper The Purpose of the Corporation that the model of business is no longer workable, is resistant to change, not consistent with the law, and for the most part, simply ignores matters of ethics. He states, each of these flaws is fatal in the business world of the twenty-first century. (Freeman, R. E.: 2008, Managing for Stakeholders, pp. 56) By using the stakeholder as a basic unit of analysis, it is more difficult to ignore matters of ethics. To explain this, Edward Freeman argues that the primary responsibility of the executive is to create as much value for stakeholders as possible, and that no individual stakeholders interest is more important than that of another stakeholder. This in turn guarantees the rights of all the stakeholders. T he problems that pose risk lie within the shareholders capitalism theory. Furthermore, if the stakeholder theory is examined, one would find that all stakeholders have rights and if one is denied theirs, the others are undeniably affected. Edward Freeman further supports this with an argument about character. He explains that one of the strongest arguments for stakeholder theory concerns character because it asks executives and entrepreneurs to consider the question of what kind of company they want to create and build. (Freeman, R. E.: 2008, Managing for Stakeholders, p. 66) Finally, Freeman poses the pragmatist argument which seeks to know how we can live better, how we can create both ourselves and our communities in ways where values such as freedom and solidarity are present in our everyday lives to the maximal extent. (Freeman, R. E.: 2008, Managing for Stakeholders, p.66). For the pragmatist, business and its close relative capitalism have evolved into a social practice, an important one that we use to create value and trade with each other. Consequ ently, the stakeholder model is always aiming to find the best possible solution for all parties involved in the corporation. Its social responsibility lies within the company as a whole. Social responsibility comes in many forms and recognizing any one form means it is required to recognize all. Conversely, Friedman states that if these are social responsibilities, they are of individuals not of a business. (Friedman, The Social Responsibility of Business is to Increase Its Profits, p.52) He contends that, in any situation, the executive would be spending someone elses money for the social responsibility. For example, if the executive makes expenditures on reducing pollution beyond the amount that is in the best interest of the corporation; and he then must hire hard-core unemployed applicants instead of better qualified workmen, he is spending someones money by reducing returns to stockholders for his environmental responsibility and lowering wages of some employees by spending what he would have given to a more experienced employees. According to Friedman, if the employees, stockholders, or consumers, want to spend their money towards social responsibility then it is their money and their decision. Friedman concludes his paper by stating; in my book Capitalism and Freedom, I have called it a fundamentally subversive doctrine in a free society, and have said that is such a society, there is one and only one social responsibility of business to use its resources and engage in activities designed to increase its profits so long as it stays within the rules of the game, which is to say, engages in open and free competition without deception or fraud. (Friedman, The Social Responsibility of Business is to Increase Its Profits, p.55) Friedmans point here can be used to understand the stakeholders benefit because it is its own form of social responsibility. Who is to say that social responsibility can only be defined in narrow terms? What is clear is that no one set of criteria can unequivocally define it and if under these ambiguous circumstances a corporation manages to achieve it, then it has guaranteed the rights of the stakeholders, thus creating social responsibility. Moreover, John Boatright explains that advocates of stakeholder management are correct in their insistence that the modern for-profit corporation should serve the interests of all stakeholder groups. Where stakeholder management fails is in its refusal to recognize that a business organization working in the interests of shareholders does not have to be in conflict with the interests of stakeholder groups. Boatright assumes that this failure is due in large part, to a second mistake on the part of proponents of stakeholder management. Stakeholder management assumes that management decision making is the main vehicle by which the benefits of corporate wealth creation are distributed among stakeholders, but these benefits can also be obtained in other ways; namely by groups interacting with a corporation through the market. This is where Boatright is taking a risk in his argument because he wants the corporation to obtain its benefits externally when it can be done internally. The bene fit of the stakeholder theory is that all the rights are guaranteed from the top down, top stakeholders all the way to the consumers at the bottom of the model. When all stakes have their rights preserved by the executive equally, there is no need for the corporation to act in the best interest of the shareholders solely. The managerial model positions its shareholders at the center of the firm as the principal group for managers to worry about. Increasing shareholder value has become common wisdom in modern business and many companies have instituted complex incentive compensation plans aimed at aligning the interests of executives with the interests of shareholders. (Freeman, R. E.: 2008, Managing for Stakeholders page.57) Edward Freeman poses three arguments in regards to shareholders. Firstly, he explains that management of the firm becomes separated from the ownership of the firm and in order to be successful the top managers of the company were required to satisfy the owners, employees, suppliers, unions, and customers. If managers worried about the shareholders only, the stakeholders will in turn be harmed. When the stakeholders are harmed, the whole corporation is harmed leading to instability. From another angle, Freeman explains that the model poses harm and risk because it is so rigid. It unabashedly puts shareholders interests over and above the interests of customers, suppliers, employees, and others, as if these interests must conflict with each other. The only change that matters is the kind that is oriented toward shareholder value. In addition, Edward Freeman also explains that the law of corporations gives a less than clear answer to the question of in whose interest and for whose benefit the corporation should be governed. It has evolved to give a de facto standing to the claims of groups other than shareholders. Even more harmful is the fact that the shareholder model is not consistent with basic ethics. Practically any business decision has some ethical content or concern. Milton Friedman refers to this by stating that, responsibility of the executive is to make profits subject to law and ethical custom. The purpose of ethics is to create a better world for all of us. (Freeman, R. E.: 2008, Managing for Stakeholders p.60) Numerous theorists have argued that the main reason that the dominant model of managing for shareholders is a good one is that it leads to the best consequences for all involved. These arguments invoke Adam Smiths idea of the invisible hand, whereby each business actor pursues her own self-interest and the greatest good of all actually emerges. (Freeman, R. E.: 2008, Managing for Stakeholders p.65) However, in reality, each business actor can have a different approach and a different idea of their own self-interest which in turn, may harm the corporation internally and externally. Although the stakeholder concept has been developed in various ways, it has expressed the moral prescription that managers, in making decisions, ought to consider the interests of all above those of the few. This is proven in the laws that have evolved to protect the interests of local communities and employees of corporations through unionization. Laws such as The Equal Pay Act of 1963, the Civil Rights Act of 1964, The Clean Water Act of 1977, and the Clean Air Act of 1990, all have helped stakeholders to achieve a great level of equality. The laws that are relevant to business have evolved differently around the world, to take into account the interests of groups other than just shareholders. (page 58) The dispute between stockholder and stakeholder management revolves around the question of how best to enable each stakeholder group or corporate constituency to benefit from the wealth-creating activity of business. Stakeholder management is correct in its emphasis on the moral requirement that every stakeholder group benefit from corporate activity and to make managers aware of their responsibility to create wealth for the benefit of everyone. The stakeholder management theory is superior to the shareholder theory because in such a system of corporate governance, all the groups would share the control of the firm. Hence, the interests of the involved stakes would be to maximize the profit for all stakeholders. The most important point, however, is the social responsibility of the managers to their corporations. As has been proven, the stakeholder management theory has the responsibility to assure the stakes interests and rights through a clear guideline that has been proven to work in modern day corporations.

Century In Canada

Nations are born out of conflict, and grow and thrive by learning from their mistakes. The 20th century in Canada was responsible for an abundance of great aspects that now exist in our country. Within that era the rights of women were recognized and altered, resulting in them being considered equals to men. Our army became recognized as an elite fighting force. Japanese Canadian internment camps were put in place as a result of the bombing of Pearl Harbor displayed nothing less then an unjust act.All leading up to the passing of the Canadian Charter Of Rights And Freedoms making certain that inhumane acts that have happened in our past will not happen again. After all, those who do not learn from their mistakes are doomed to repeat it. The early years of the 21st century were important to shaping Canada as a nation. 2 major events occurred during this time that helped to create our identity; the feminist movement began to take hold within and beyond our borders, as well as beginning to be recognized as a world-class military force.Women (prior to the famous five) were tremendously discriminated against and viewed as incapable of doing many acts. Emily Murphy, a self-taught legal expert, who championed in women and children's rights felt strongly in fighting for gender equality. In 1903 she began a campaign focusing on property rights of married women. With her hard work and dedication in 1911 the Dower Act was passed. The act stated that women had the right to one third of their husband's property and allowed for the surviving spouse to become the legal owner of the home.This signified a huge step for women because it proved there rights were beginning to be recognized and there was hope for one day being considered equals to men. Her career continued to progress when she along with other concerned women attended a trial for Edmonton prostitutes on October 17, 1933. The women were ordered to leave the court because the case was not to be viewed by â€Å"mixed company'. Murphy was furious and proposed that if women weren't allowed to view the case there should be a separate court for women, run by women.Emily later went on to become a Judge, Just like the generations of male lawyers/Judges in her family. Emily had to cope with the hurtful remarks from male lawyers questioning how she can be a Judge, and therefore be granted powers o make important/ valuable decisions, if she is not even considered ‘a person'. The law essentially categorized women as ‘crazy, unstable lunatics' and not considered a person. This got her fuming, fighting until there was Justice. Murphy gathered up 4 other women with the same political views as her, and together they made up the famous five.Emily, Henrietta Edwards, Irene Parlay, Louise McKinney and Nellie McClure were all strong willed women coming from well educated backgrounds and were devoted to social change and women suffrage. With the support of the female citizens they produced a petition and brought it to the Supreme Court. After a nail biting 5 weeks of debates the petition was denied. The women however were not discouraged and delivered the petition to Britain Privy Council, the highest role of government in Canada.On October 18, 1929 the Privy Council announces the Persons Case, explaining that women were legally considered persons and therefore could become members of the Senate of Canada. There is no question about it this milestone was the first of many for Canadian women, and because of the efforts of the Famous Five's women would now be considered equals to their male counterparts. The women of today owe a tremendous amount of gratitude for their efforts. World War I lasted from July of 1914 to November of 1918. During this time Canadians began to build an identity for themselves.This is evident during the battle of Vim Ridge. Canadian troops were ordered by Britain to conquer Vim Ridge, a prime piece of land that would be critical to the allies' efforts. Un fortunately the Germans had control over it, but Canadian troops lead by General Bang and General Currie were going to set out to conquer the ridge. Prior to the planned invasion the Canadian troops had to undergo weeks of exhausting practice drills, as it was crucial o stay undetected and surprise the enemy and that everything was executed perfectly, or the whole mission would be Jeopardized.Canadian aircrafts flew overhead the ridge and photographed what the ridge looked like. Returning back to Canadian grounds with information in hand this allowed for Canadian forces to set up an exact replica of what to expect during the attack in terms of characteristics of the ridge, and where the Germans were standing guard. Troops trained for weeks on the recreated Vim Ridge set, until they knew it so well they could perform their duties blindfolded. The Canadian forces had also set in place 2 techniques that would help them take over the ridge after they emerged from the tunnels being built to get as close as they can.They then would execute the creeping barrage and vim glide. The strategy consisted of making a smoke screen in front of them (produced by bombs) and crawling low to the ground, placing them beyond enemy lines. This allowed for the forces, when they were ready to attack, to take the enemy by surprise and hopefully conquer. On April 9, 1917 all 4 divisions of Canada's troops attacked, he plan was executed exactly as planned and the Canadians conquered the ridge. However, this battle was a tragic one as Canada was faced with heavy casualties, resulting in 3600 soldiers killed.The victory for Canada resulted in a nation and its armed forces being recognized for their brave men as well as smart planning and execution. Because of Vim Ridge we began to be a nation worth fearing. After the horror of the First World War and the tremendous achievement for women's rights, Canada was a nation well on it's way to great success. Though the war was devastating, we ulti mately came out of it stronger. Moving into the ass's women roles were continuing to evolve. The flapper girl age was beginning.What brought upon this revolution was the fact that during the war women had to disobey societies views on what a women should and should not do by stepping up and performing the boys jobs while they were off serving in the war. They had to remove their aprons, and leave the stove. This was a time they needed to step up and take over their husband's jobs in order to still provide for their family and be able to put dinner on the table. Once the war had ended women were not going to return back to their old roles. Women didn't want, and didn't feel like, they needed to succumb to society.They were comfortable in their new lives, though it was only intended to be temporary. This new wave of young women wanted to stand out and be different. All of these factors birthed the flapper girl. She appeared as a boy, dressed with short hair, higher skirts, and flatten ed chests. They had a strong appearance and attitude about them they felt liberated. The younger generation saw the time frame as a perfect opportunity to introduce this new style, given that women's rights were evolving, this would bring more attention onto them. It was overall a rebellious movement of expectations of women. (http://history sass. About. Mom/odd/sass/a/flappers. HTML) After the Japanese attacked Pearl Harbor, Hawaii on December 7, 1941 Canada took a step backwards on human rights and discrimination against the Japanese. At the time there were 22,000 Japanese Canadians living in British Columbia, some of wham's ancestors were the first immigrants coming for work to Canada in the sass. Though they had always been discriminated against by the largely white Canadian society, it was nothing compared to what was about to come. Days after the Pearl Harbor attack, Canadian companies began to fire all Japanese workers beginning with the Canadian Pacific Railways.Matters got worse when Japanese forces attacked Hong Kong and killed over 2000 Canadian soldiers stationed there for training. The Japanese began to be referred to as SAPS, and signs were being posted around the province harshly stating, â€Å"Keep out†. It was then the Federal Government designated a 100-mile wide strip, as a protected area to keep all Japanese until they would be further placed inland. They were finally ordered to pack a small suitcase and live in inverted over animal stalls awaiting their train to arrive. (http://www. CB. Ca/history/ OPPOSITENESS EPOCH APPEAL. HTML). Husbands, wives and children were all separated. The men were sent to work on road gangs, whereas the women and children were sent to shantytowns in the B. C wilderness. In January of 1943 the government forced the sale of all property/ belonging to the Japanese Canadians that includes their homes, cars and other valuables. The reasoning behind this was to erase any memories the Japanese built in Canada a nd to convince them not to assume living here when the war over. The writing was essentially on the walls, the Japanese were no longer welcome.Once the war ended the B. C federal government decided to release all Japanese from the camps. The Japanese were then faced with choosing between deportations back to Japan, specifically parts that were destroyed during the war, or moving east into the Rocky Mountains. The majority of them chose to move to Ontario, Quebec and the Prairies. Many families did move back to Japan as well. It was a long time coming, but finally on April 1st, 1949 after much protest, Japanese Canadians were finally allowed the freedom to live anywhere in Canada.

Benefits of Early Literacy Learning Essay

Education is a fundamental aspect of a person’s social, economic, and emotional developmental. Starting education early is therefore advantageous. Focusing specifically on early literacy; statistics prove that an early literary development can radically improve a child’s chance for a formidable career. Early literacy developmental practices have been taking place for many years now. Many different literacy programs offer statistical and other information to demonstrate the benefits of learning literacy early. In true effect of the experimental learning and teaching; the instructors keep detailed records of the lessons taught and the grade improvements of the students. The other side of the early literacy learning is to have a control group that they are teaching without the focus on early literacy, thus being able to generate a detailed analysis of the children’s improvements and success rate. One high quality literacy program released details about their program and the outcome of the program on their students. As stated by two authors, â€Å"Strengths in the overall program that services provided resided in†¦ literacy links across the curriculum and throughout the day. † (Arthur and Makin) In this same educational facility they had a record of which programs were the strongest and which programs did not demonstrate as well. â€Å"There were seven ECLLS [Early Childhood Language and Literacy Scale] items on which more than 50 per cent of the rooms observed received a high rating (six or seven out of a total seven). These were as follows: furniture for routine care, play and learning room; room arrangement for play; encouraging children to communicate; fine motor activities; staff-child interactions; and program schedule and grouping. † Depicting the importance of structured play times and environmental factors can have on learning. Also stating the â€Å"Four services received a high rating for the new literacy subscale, with most settings scoring 3 out of seven. In the settings with the high ratings staff were extending children’s literacy through the following practices: reading environmental print with children; integrating literacy across the curriculum and throughout the day; engaging in literacy interactions with children; and promoting metalinguistic development† (Arthur and Makin) In this particular educational facility the staff used all resources to their advantage, from the simple hand washing sigh to other hygienic posters. The staff had set aside times for writing, play, and reading to help incorporate forms of literacy into all things done through the day. Through their curriculum and the observations of others this facility was able to statistically prove that an early start with literacy highly benefited these children. When considering the statistics there are some graphs that support, and show that early literacy is essential to doing well over all. â€Å"The impact of Teacher Responsively Education on Preschoolers’ Language and Literacy Skills,† provides direct evidence in standard chart format with a control group and tested group. (American Journal p323) Showing a direct relationship between early literacy and developmental improvement, a second graph from the American Journal, the graph shows the improvements from the fall testing and the spring testing of the impacts of early literacy. The graph shows the statistical improvement between the two testing times, providing direct evidence of the impact on the children tested. There are many facilities that provide the numbers on which the improvement was made; it spans all over the globe. Over all upon testing during the fall semester the control group initially started roughly at 3. 3%; where are the test group tested at a slightly higher 3. 4%. During the spring semester the control group tested lower still at print concept than the test group rising only . 28% from the initial testing scores. Reaching across the seas Australia has also been participating in the analysis of early literacy and its benefits on the overall aspect of children’s lives. In an article titled â€Å"Books, bytes and brains,† authors Hopkins, Brookes, and Green dive deeply into early literacy development and its impact on all areas of the lives of children. As stated in this article, â€Å"Literacy and numeracy are core life skills, the [acquisition of which has] profound consequences for individuals, families, communities and nations. † Literacy is essential these authors believe to a child’s overall future, â€Å"Improving literacy in contemporary society has been amply demonstrated to improve live chances for individuals across divers domains including health, mental health, housing, educational outcomes, employment opportunities, income levels, involvement with crime, and civic participation. † (Hopkins, Brookes, and Green) So many different areas are affected by a person’s literacy from the simple school grades to if they’ll end up in prison. Hopkins, ect al. states that â€Å"Traditional kinds of literacy skills are measured in programs such as NAPLAN are based on an understanding of a skilled reader as someone who ‘locates, understands, and interprets written information in prose and documents – including manuals, graphs, and schedules- to perform tasks; learns from text by determining the main idea or essential message; identifies relevant details, facts, and specifications; infers or locates the meaning of unknown or technical vocabulary; and judges the accuracy, appropriateness, style, and plausibility of reports, proposals, or theories of other writers. † With their definition of what an actual skilled reader is, it can seem almost impossible for a child to gain all those skills in their short school career. Therefore starting literacy early can give a child the advantage of gaining the firm foundation of those skills before they are being presented to them in the classroom. When starting the early foundation of early literacy there are some draw backs to the programs, or glitches that haven’t been worked out yet. â€Å"Analysis of data from the rating scales, staff interviews and parent focus groups indicates that a number of areas required further development. Even for those settings that rated highly for literacy. These include, building on home experiences; extending children’s home languages and literacies; utilizing technology and popular culture; and integrating literacy resources and staff-child interactions in dramatic play. † (Arthur, Makin) Improvement in these areas has been underway since the date of the article, in this program as well as others. Implementing home language and literacies could have a drastic effect on the early learning literacy because many homes now in America are not solely English speaking homes, where most lessons in school or an Early Learning Academy to teach early literacy are taught in English. Tying into home experiences can help a child more associate the lesson being taught because they can incorporate the object, lesson, or event with words or effective language skills. Even with the hiccups the early literacy programs have, there are visible benefits of the lessons they are teaching. Seeing the results of the early literacy programs is phenomenal, but looking at the other side research shows some negative effects of what happens when early literacy is not implemented. â€Å"Recent research shows that children who are ‘raised in a [non-academically] oriented environments have less experience using decontextualized language than their peers. †¦These children may communicate more readily through using images, physical activity, and symbolic representation’. † (Hopkins, Brookes and Green) With that research a child with the early literacy training entering the second grade for example has a better chance of being able to vocalize opinions or even understanding of a lesson than a child who has had no early literacy training. With education being at the heart of every aspect of life it is highly important to give children every chance to succeed. Word Count:1,244.

The Scarlet Letter Questions for Discussion

The Scarlet Letter Questions for Discussion The Scarlet Letter is a seminal work of American literature written by New Englander Nathaniel Hawthorne and published in 1850. It tells the story of Hester Prynne, a seamstress newly arrived in the New World from England, whose husband, Roger Chillingworth, is presumed dead. She and local pastor Arthur Dimmesdale have a romantic interlude, and Hester gives birth to their daughter, Pearl. Hester is  convicted of adultery, a serious crime in the time period of the book, and sentenced to wear the scarlet letter A on her clothing for the rest of her life. Hawthorne wrote The Scarlet Letter more than a century after the events in the novel would have occurred, but it is not difficult to discern his contempt for Bostons Puritans and their rigid religious views.

Recent Changes In Organisational Form And Personnel Strategies Essay

Recent Changes In Organisational Form And Personnel Strategies - Essay Example Differences between the connotations of the words "labor" and "work† suggest the reorienting effect that Braverman's formulation had on views regarding work, workers, and the workplace (Rowlinson, 2000, p.13-14). Labor is an economic commodity exchanged in the market. Braverman held that work had been degraded by capitalism thus turned into mere labor. Taylorism separated the hand from the brain and vested the brains in management and the hands in labor. Work became deskilled as technological and bureaucratic controls supplanted the self-direction of skilled workers. This process of deskilling standardized work activities robbed work of meaning, leveling skill distinctions among workers. It enlarged and homogenized the proletariat, which came to include clerical and semi-professional occupations. Braverman's focus on skills had the effect of conceptualizing the outcomes of the industrial transformation as technological, psychological, and economic rather than social. Harry Brav erman does not make clear the definition of skill but sees the degradation process as involving the separation of mental and physical activities. One might be concluded that Harry Braverman has identified skills as cognitive abilities of workers, then generalized beyond that point to make skills technical characteristics of jobs. Sociological conceptions of work based on workers' relations to each other, group control over activities, and normative definitions of technical relations are missing.

Molecular Recognition and Drug Design Essay Example | Topics and Well Written Essays - 1000 words

Molecular Recognition and Drug Design - Essay Example Prediction of 3D structure of protein or target molecule was quite tedious and uncertain due to many of the protein targets are membrane bound and in case of soluble targets like enzymes, they exist in quite dynamic condition in side the body and its structure-function is tightly regulated by microenvironment. But In recent past this problem was solved at quite extant due to development in techniques like NMR and X-ray diffraction leads to generation of hug databases of protein structures, Along with this development in computational capability have deeply influence the over all process. Now we have number of software and models by which one can predict structure of protein based on just amino acid sequences, classical example if homology modeling of protein folding. In post genomic era high throughput protein expression and structure determination by X-ray diffraction augmented by homology modeling makes key process for new drug development program. Quantitative Structure Activity Relationship (QSAR) is an area of computational research where virtual model was developed to determines binding proertise of ligand to its target molecules as well as to predict toxicological potential of existing or hypothetical molecules. QSAR is generally employed to establish correlation between structure and electronic properties of ligand molecules which influence its binding to specific drug target and general target molecules. Initially it was used to predict ligand having very high affinity towards target molecules but now it is extended to predict its diffusion, adsorption, toxicity, metabolism and finally elimination. There are different types of QSAR like 1D, 2- (Lill, 2007) (Mller, 2003)D etc based on number of parameters taken for model prediction. Table 1 describes different mode of QSAR and parameters involved in it. Table:1 (Lill, 2007) Initially QSAR was developed on single parameters like pKa value or solubility of ligand molecules and based on that prediction was carried out (1D-QSAR). Hansch e'tal has included physic-chemical properties like functional groups and atomic configuration in to it. They also correlated these properties to biological activity of ligand. (2D-QSAR). After 1980s increasing number of 3D structures of proteins makes it more feasible to include three dimensional structure of protein-ligand to understand its interaction. Than after Structure based deign (SBD) becomes routine process for new drug development process. Here after identification of target molecule different ligands were searched and analyzed for its docking to target molecules by process called dynamic optimization (MD). Based on this Technique it is possible to identified best binding mode of any given ligand molecule with target. In 1988 Comparative molecular field analysis (CoMFA) was introduced in QSAR which leads to first time demonstration of structure -function co-relation (3D-QSAR). Development of 3D QSAR made task simpler but later it was realized that 3D QSAR based models are not always gives complete picture but fails to explain processes like Induced fit
