Competitive Marketing Strategy Adopted By Apple Inc. - 825 Words
Analysing The Competitive Marketing Strategy Adopted By Apple Inc. (Essay Sample) Content: TITLE:COURSE:COURSE CODE:STUDENTS NAME:INSTRUCTORS NAME:The technological market especially when it comes to consumer electronic products has a wide range of competitors. The competition does intensify with new innovations that are being created that appeal to the end customer. The Apple electronics product does operate in Monopolistic competitive market. The market reflects an imperfect competitive environment. The monopolistic competitive market refers to a market where there are large numbers of seller but the products that are being offered are not identical.The market is most suitable for the Apple electronic products because of the following reasons. Firstly, there are large numbers of sellers in the electronic consumer products. They include LG electronics, Samsung, Lenovo, Compaq, Acer, IBM, and Microsoft among others. Secondly, the products of different sellers are different in quality. The companies offer products that are within the same price range. In ord er to penetrate the market it is pertinent for the firms to invest in quality to ensure they draw customers to their product (Mankiw, 2015). There is a notion that quality is expensive it is true when applied to selling the product to the end customer. In order for the firm not to incur the high cost of producing high cost products it is pertinent that they need to outsource their services.In the production of Apple electronics the company has to outsource their production activities to China and India. The reason for selecting these two countries is that there are many experts who offer their services at reduced cost hence saving the company its finances. The third characteristic is that advertisement plays an integral role in the case of monopolistic competition. Through propaganda, a seller can charge higher price for their product (Mankiw, 2015). Based on this characteristic the company needs to invest in quality advertisements. The advertisement should focus more on the feature s their products offer when compared to their competitors. Additionally, they should incorporate music and artistic art to imprint the advert in the minds of the end customer.According to the research conducted by Buvik 2001, the customers in the technological electronic market are impulse buyers who are drawn by the inclusion of new features to a product. The customers especially those purchasing mobile phones and laptops are willing to spend more to purchase a diverse that reflects class, style and is efficient. Based on this aspect selecting a suitable target market is important for the company since it will enable them to satisfy the needs of their customers. Apple Company does focus on the high end customers who are more concerned about the features of the product rather that cost.In the international frontier Apple Company is renowned for producing quality products for their customers. Building on this brand name the company has an opportunity of selling their electronic produ cts massively to their select customer market. With the introduction of international trade and the efforts to reduce trade barriers the entire globe is opening up to trade. The aspect has resulted in the growth of economies in various parts of the continent. The growth of economies is an indication that the people have disposable income to invest in the purchase of electronic products (Mankiw, 2015) .The Apple electronic products can take advantage of this new market.Additionally, in order to achieve a comparative advantage the Apple Company focuses on exclusive marketing. The company has set up their own stores that sell their products. The aspect of exclusivity guarantees the customers that they are purchasing quality and original products from the retail stores (Buvik, 2001).Factors that will affect the demand and supply of the Apple electronic products include: change in economic conditions when there is economic prosperity in the country demand for products increase while duri ng depression it decreases. Secondly, successful advertisement does increase its demand. Thirdly, rate of taxes when the taxes levied are high the supply falls because the cost of production increases making the prices of the products to increase. Fourthly, improvements in production methods tend to decrease the production cost leading to the decline in the prices of the products. Lastly, change in customer tastes and cost of production. The demand for new features on the electronic products will tend to increase the demand for the new materials which increases the cost of production that leads to high prices of the products (Kontratenko, 2013).Total revenue refers to the amount that is obtained by a firm when selling a specific commodity in the market. The total revenue is affected by increase in competition that divides the market, change in government policy, increase in inflation that affects the prices of raw materials, employee strikes halting the production, and price elastic ity of demand among other reasons (Gilblin and Rooney, 2015).When measuring cost to be precise cost of production a number of factors are taken into consideration. They include: cost of raw materials, labor, interest on capital, publicity expenses, replacement and repair charges of machinery, and finally the existence of sufficient profits to induce production. The above costs often lead to the concept of opportunity cost where the company has to decide what aspects to forego in order for them to achieve their target profit margins (Inglenbleek, and Van der Lans, 2013).The external environment and government policy has a major impact on the firms engaged ...

The World Economic Scenario Of Brazil - 1722 Words
A lot has changed in the world economic scenario over the past 25 years. World trade has increased from $8.7 trillion in 1990 to over $46 trillion in 2014 (Global Economic Prospects 2016: 219). These numbers reflect a growth in the trade of goods and services amongst different nations, which came as a result of globalization. With that being said, an economic interdependence has been formed. Countries that have been actively participating in this phenomenon by joining trade agreements, eliminating tariffs, and facilitating commerce have highly benefited from this transformation. On the other hand, nations that have isolated themselves from these opportunities through protectionist policies, have been negatively impacted. Members involved in these trading blocs gain a competitive edge over those who opted to stay out. Brazil serves as a good example of the negative effects that adapting a protectionist policy may have on a nation s economy. The country has access to a vast amount of p rimary resources, including soy beans, oil, sugar cane, iron ore, coffee, and orange juice. Nonetheless, its exports account for a mere 11.2% of its GDP, in comparison to the world average, which in 2015, amounted for a total of 29.3% (World Bank Group, 2016).

Ritual Use of Cacao in Maya Civilization - 1903 Words
Ritual Use of Cacao in Maya Civilization This paper aims to explore and confirm the ceremonial and ritual importance of Theobroma cacao to the Maya civilization and its various uses therein. Firstly, I will provide a brief overview of the cultural history of cacao, which is known as kakaw in the Maya language. Next, I will examine the connection between cacao and ancient Maya religion, which is the basis for its importance to the Maya culture. I will then discuss the ritual and ceremonial significance of cacao and its forms of use, based on the analysis of Maya hieroglyphs and iconography, as well as ethnohistorical, ethnographic, and other historical accounts, and the recent research by archaeologists who have found cacao residues in ancient pottery. The cacao tree (Theobroma cacao L.) is native to the northwest Amazon basin of South America and the wild species was spread by humans into Southern Mexico and Central America, where it is thought to have been domesticated (Ogata et al. 2006). The data collected by Ogata et al. (2006) supports Mesoamerica as a center of cacao domestication, but also suggests a possible secondary area of domestication in South America. At first, only the cacao pulp was used for its sweet flavour, yet it wasnââ¬â¢t until 1800 BC that the inhabitants of this region discovered how to turn the cacao seeds into chocolate through a process of drying, roasting, and grinding the cacao seeds (Coe and Coe 1996).

Raja Ampat being one of the major tourist attraction. This place comprises of several volcanic rock present in the mid of the ocean along with coral reefs and several marine life.

Belitung Islands has several beautiful beaches that are a major tourist attraction. Bali is famous for surfing, rafting and parasailing. Lake Toba is also a major tourist attraction due to its refreshing atmosphere. Other major tourist attractions are Tanjung Putting, Derawan Islands, Karimun Java and Toraja. Tourism in Indonesia became an important matter since 1995 when several workshops were held to strengthen ecotourism in Indonesia. These workshops emphasized on the importance of conserving nature and developed environment related education for the visitors of ecotourism destinations. Several environmentalists and N GO drove the Indonesian ecotourism development activities. Literature review: According to Fennel (2014), eco-tourism refers to the environmentally responsible travelling that involves enjoying and appreciating the nature that promotes conservation and has lower adverse impacts on the nature that provides benefits to both economy and local people. Eco-tourism emphasizes on conservation, community participation, education and responsibility of the traveler. Eco-tourism becomes necessary in order to reduce the adverse impacts of tourism on sensitive areas. Eco-tourism aims at preventing environmental degradation. Local communities are highly affected by tourism as tourism affects the indigenous culture to a great extent. Eco-tourism reduces all the negative impacts that tourism might cause to a place. On the contrary, Chiu, Lee Chen (2014) stated that eco-tourism activities also generate negative impacts that harm the natural environment. The impact on the environment can be in the form of alterations in the initial value of the environment. Continued negative impact on the environment can result in pollution and degradation of the environment. Environmental degradation involves destruction of wildlife, vegetation, landscapes and coral reefs. These negative impacts are a result of improper plan of tourist management, lack of knowledge of the local community and paying less attention to the environmental capacity. The negative environmental impacts involve soil erosion, land degradation, increase in wastes and noise pollution. This is the point at which a territorial territory creates from investigation to contribution and after that into the advancement phase of the tourist region life cycle model. During the last stage there can be both immediate and aberrant ecological effects through the development of superstructure, for example, lodgings, eateries, and shops, and framework, for example, streets and power supply. As the goal grows, more voyagers search out the experience, thusly, their effects increment likewise. The prerequisite for water for washing, squander transfer and drinking increments. Waterways can be changed, exorbitantly separated, and contaminated by the request put by the facility. Clamor contamination has the ability to aggravate natural life and change conduct, and light contamination can disturb the sustaining and regenerative conduct of numerous animals. At the point when control is provided by diesel or fuel generators there is extra clamor and contamination. General waste and junk are additionally an aftereffect of the offices. As more sightseers land there is an expansion in sustenance and drinks devoured, which thus makes squander plastic and non-biodegradable items. However, according to Thys et al., (2016), eco-tourism has several positive impacts on the environment as it emphasizes on conservation, community participation, education and responsibility of the traveler. Eco-tourism becomes necessary in order to reduce the adverse impacts of tourism on sensitive areas. Eco-tourism aims at preventing environmental degradation. Eco-tourism aids in creating an efficient appreciation of the natural resources of Indonesia that includes wildlife, landscapes and coral reefs. Eco-tourism encourages protection of the environment by creating several national parks, marine parks and wildlife reserves. The funds for conserving the environment are generated through entrance fees of parks and sanctuaries, safari tours and camping fees. Eco-tourism helps in protecting the ecosystem by offering employment alternatives that reduces the damage caused to the environment in the form of excessive farming, clearance of land and over- fishing. On the other hand, Iasha et al., (2015) stated that eco-tourism affects the society of the destination place by bringing several changes in the lives of the local communities. Eco-tourism also affects the culture of the local people by bringing noticeable changes in the customs and rituals of the local communities. The host communities are often considered as the weaker party in the tourism industry as they are highly influenced by the likes and dislikes of the tourists. Eco-tourism influences the local communities to such an extent that there are several changes in the values and behaviors of the host communities. These changes occur in family relationships, lifestyles and community structure. The religious rituals and ethnic festivals of the local communities often get altered in order to make it more attractive to the tourists. This leads to reconstructed ethnicity. There is always a possibility of cultural clashes when a tourist visits a new tourist place if the social relationsh ips between the tourists and the local people are not satisfactory. On the contrary, Butarbutar Soemarno (2013) stated that eco-tourism improves the socio- cultural climate of the host country by preserving the environment and generating revenue that builds up social class of the local communities. Eco-tourism generates revenue for the local communities and provides incentives for preserving their culture, their heritage sites and customs. Eco-tourism encourages the host community to take interest in local arts and crafts, ceremonies, songs, dance and traditional activities. Eco-tourism enables the local communities to discover a wider world, new experiences and new ideas and thoughts. According to Indiati Munir (2016), severe economical impacts of eco-tourism are observed in the form of depletion of the natural resources and degradation of the environment for which several corrective actions are taken that involve spending on improving the environment. Increase in eco-tourism results in foreign ownership and revenues shifting from the local communities to the other nations. This poses potential harm to the local businesses. Tourism leads to increase in the price of the properties that are located near the tourist spots that pushes out the local people and encourages the business to take advantage of the tourist spending. Eco-tourism leads to economic inequalities as the patterns of consumptions of the tourists are different from that of the local communities. The local people often try to copy the patterns of consumptions of the tourists that increases economic tensions. However, according to Romadhon et al., (2014), eco-tourism also generates several positive impacts on the economy. Eco-tourism provides economic benefits to both the communities existing in that area as well as to the local Government. The tourists spend a lot when they visit a place. These spending involve using local transport, staying in local hotels, visiting tourist places and spending on food. The tourists also spend a lot of money on buying local goods and services that boosts the business of the local businessmen. The income of the local communities increase as a result of eco-tourism. Eco-tourism helps in generating employment opportunities that involves accommodation, entertainment, food services, drink services, shopping and manufacturing (Bailey, 2016). Conclusion: Therefore, it can be concluded that eco-tourism has both negative and positive impacts on the environment, social and cultural climate as well as on the economy. The environmental impacts affect the natures carrying capacity and affects the quality of land, vegetation, air and water quality, wildlife and other natural phenomena. The social and cultural impacts refer to the interaction of the host communities with the tourist that affects their lifestyles, culture, religion, ethnics and their attitudes and behaviors (Wiwin Indiarti, Hum Munir, 2016). Tourism in sensitive localities might either lead to loss of culture or preservation of the customs and rituals with the aid of increased resources and revenues. The economic impacts can also be positive and negative. Eco-tourism leads to increase in revenues from the tourist spending. These spending involve using local transport, staying in local hotels, visiting tourist places and spending on food. The tourists also spend a lot of mone y on buying local goods and services that boosts the business of the local businessmen. However, eco-tourism might also lead to economic inequalities, as the patterns of consumptions of the tourists are different from that of the local communities. The local people often try to copy the patterns of consumptions of the tourists that increases economic tensions (Pamungkas, Indriyani Hakim, 2013). Policy suggestions: Indonesia a nation rich in both natural and social assets and comprises of several tourist locations that involves islands, natural parks, coral reefs, volcano, sea beaches and many more. Indonesia is highly dependent upon tourism as it is a major source of revenue. Therefore, the following are the policy suggestions that shall improve the eco-tourism in Indonesia: Development of infrastructure: The financial institutions of Indonesia must assist in the development of infrastructure in the major tourist spots. Accommodation: Establishment of tourist in the major tourist locations shall further boost the tourism industry in Indonesia. Marketing: Eco-tourism in Indonesia must be properly advertised and promoted in order to attract greater number of tourists. Security measures: The safety of the tourists must be improved especially during some sports activities such as paragliding, scuba diving, trekking and other sport activities. Waste management: Increase in tourism shall increase the amount of wastes generated in the tourist locations. Therefore, proper policies must be formed to manage and dispose the wastes generated as a result of tourism. Environmental auditing: The environment must be constantly monitored and in case of any negative impacts, control measures must be taken instantly. References: Bailey, J. (2016).

The beliefs and practices associated with Holy Communion Essay Example
The beliefs and practices associated with Holy Communion Paper Holy Communion is a practice performed by Christians, for a number of reasons relating to belief and worship. While the ways in which Holy Communion is celebrated differ among the churches, communion prayers tend to revolve around the story of the last supper and the act of Christ giving his disciples bread and wine, and declaring it as his body and blood. This is the story of the last supper, the last meal Jesus shared with his disciples on the night of the Passover before he was betrayed by Judas, arrested and then executed. During the meal Jesus and his disciples were at the supper table and he broke some bread, gave it to his disciples and said, This is my body which is given for you. Every time you eat bread, think of me. Jesus took a cup of wine and gave it to the disciples and told them to drink from the cup and said, This wine is my blood that will be shed to remove the sins of all who come to believe in me and it is the start of a new agreement between God and mankind. The significance of this event, has been interpreted by the churches in different ways, which in turn has led to the variety of ways in which Communion is practiced among the churches.

While the majority of churches practice Holy Communion, there are a few churches that dont practice it at all, such as the Salvation Army and the Quakers. While there are some differences in the way that Communion is celebrated between the Orthodox and Roman Catholic churches (both high churches) the difference between the Roman Catholic church and Methodist church (low church) is far more substantial. There are two fundamental differences. The first and perhaps the most important difference is in the interpretation by each church of the way in which celebrating Holy Communion affects the individual taking part. This is known as the issue of belief associated with Holy Communion. This is explained in more detail in the paragraphs below. The second important difference, one that is easier to recognise, is in the way in which churches prepare for and perform Holy Communion. While some churches continue to adopt traditional methods to perform Holy Communion others adopt a far more informal approach. The high churches, such as the Roman Catholic and Orthodox, stick to very traditional methods and attach central importance to taking Holy Communion. By contrast low churches such as Baptist and Methodist, while they do celebrate Holy Communion, they do not regard it as being any where near as important as the higher churches, and tend to celebrate it in a much more relaxed and informal manner. The following are examples of how individual churches perform Holy Communion and the reasons they attach different levels of importance to it. Catholics refer to Communion as the Eucharist and practice it in a very traditional way. The first thing to note is that while some churches celebrate Communion on a weekly or more infrequent basis, Catholics can take Communion every day. It is not a requirement for Roman Catholics to go every morning but it is strongly encouraged by the church to attend Communion (Mass) as often as possible and at least once a week. This explains why Communion is so very important for Roman Catholics and is often described as the central form of catholic worship. The only person allowed to administer Communion is a validly ordained Priest acting in the role of Christ. In other words, the Priest represents Christ and his body and his blood are represented by wafers made from wheat (called the host) and wine made from grapes. Catholics believe that the Holy Spirit is contained within the wafers and the wine and that in the act of receiving communion the congregation is taking in the Holy Spirit. It is therefore central to the Catholic faith, so much so that they believe that by taking communion they are taking in the strength of the Holy Spirit which will help them lead a life free of sin. The quotation from John 6:53 sums up the overall belief held by Roman Catholics In Communion, we are eating the True Body and Blood of Jesus Christ, without which you shall not have life in you. Their interpretation of the story of the bread and wine is very literal. Communion can only be taken by those who have been baptised into the Catholic faith and have taken their First Holy Communion. This usually happens around the age of 7 or 8. The traditional Catholic church service (mass) follows a set format (liturgy) and concludes with the taking of Communion. During Communion wafers are used instead of bread, fermented wine is used which is taken from a shared chalice. The priest holds up the wafer as he says, the body of Christ and hands it over to the person receiving communion at which point this person would say, Amen. Then the priest pours out the wine and says, The blood of Christ at which point the person receiving communion takes the chalice and says, Amen. Any leftover bread or wine is either eaten by the priest or kept as reserved sacrament for the infirm in the parish. This routine tends to differ only very slightly between the high churches. The low churches have a much less traditional way of celebrating communion, which tends to link to the fact that they believe the bread and wine only represent the body and blood of Christ in a metaphorical sense, but that by performing communion they are only reminding themselves of Jesus, and believe that his spirit is no more present than usual. For example, Baptist and Methodist churches also hold Communion, which they call the Lords Supper, but they use less traditional methods of practice and hold it in lower regards. The members of these lower churches do not actually accept the belief that Jesus spirit is present within the bread and wine, and so do not take the service as seriously, but they do perform the Lords Supper with the intention of remembering Jesus. The argument used by these lower church members to support their views is that Jesus meant the bread and wine was his body and blood in a metaphorical sense, and the phrase they value most during the Last Supper is when Jesus said, Do this in memory of me. A typical Baptist communion takes place monthly and the only qualification necessary to receive The Lords Supper is a membership with the church. Examples of how the Baptist version of communion differs from the higher church versions of communion are the fact that a table is used instead of an altar, there is no set form (Liturgy), there is no main service and there is no need for an ordained minister. Bread is used but instead of wine they either use unfermented wine or fruit juice and instead of drinking this from a shared chalice they have individual glasses. The people receiving the Lords Supper remain in their seats while receiving it and they all drink at the same time. Any bread left over is given away and any unfermented wine or fruit juice is returned to the bottle. It is clear to see that from the differences in practice, the lower churches believe Communion to be less important. For example, the fact that they return the wine or juice to the bottle shows that they do not believe it to be the blood of Christ, as otherwise they would treat it with higher respect. Methodists also receive communion in a less traditional way but they do have a main service while taking Communion and an ordained minister is necessary. They also would have to go up to the table to receive The Lords Supper and do not all drink at the same time. Other churches, such as the Church of England would celebrate Communion, or as it is known in the Church of England, Eucharist, in an almost identical way to the Roman Catholic church, the only differences being that they use both an altar and a table and they may also use bread instead of wafers. This almost identically shared practice displays almost identical beliefs shared by both members of the churches regarding communion. Christians that do not have a specific building in which to worship and attend communion often practice their religion at home alone or with others in what is called a house church. The practices will remain roughly the same from house to house, due to a lack of an altar or ordained minister, but the beliefs will vary depending on the individual receiving Communion.

How to Write a Character Analysis
How to Write a Character Analysis Being mindful of subtle hints, like mood changes and reactions that might provide insight into your characters personality, can help you write a character analysis. Describe the Characters Personality We get to know the characters in our stories through the things they say, feel, and do. Its not as difficult as it may seem to figure out personality traits based on a characters thoughts and behaviors: Say cheese! the exasperated photographer shouted, as she pointed her camera toward the group of squirming children. Margot displayed her broadest, most convincing fake smile as she inched ever-closer to her younger cousin. Just as the photographers finger twitched over the shutter button, Margot leaned into her young cousins side and pinched hard. The boy let out a yelp, just as the camera clicked. You can probably make some assumptions about Margot from the brief segment above. If you had to name three character traits to describe her, what would they be? Is she a nice, innocent girl? Doesnt seem like it from this passage. From the brief paragraph, we can assume that shes apparently sneaky, mean, and deceptive. Determine the Character Type of Your Protagonist You will receive clues about personality through a characters words, actions, reactions, feelings, movements, thoughts, and mannerisms. Even a characters opinions can help you learn more about the individual, and you may discover that the person fits one of these stock character types: Flat character. A flat character has one or two personality traits that dont change. The flat character can play a major or a minor role.Round character. A round character has many complex traits; those traits develop and change in a story. A round character seems more real than a flat character because real people are complex.Stock or stereotype character. Stock characters are stereotypes, such as hot-tempered redheads, stingy businessmen, and absent-minded professors. They are often found in genre fiction (romance novels and mysteries, for example), and are usually flat characters. They are often used as a tool to move a plot forward.Static character. A static character never changes. A loud, obnoxious background character who remains the same throughout the story is static. A boring character who is never changed by events is also static.Dynamic character. Unlike a static character, a dynamic character does change and grow as the story unfolds. Dynamic characters respond to events and experience changes in attitude or outlook. The character might go through a transformation during the course of the storyline, and grow as a result of actions that took place. Define Your Characters Role in the Work Youre Analyzing When you write a character analysis, you must define that characters role. Identifying the character type and personality traits can help you better understand what the larger role of the character is within the story.à The character either plays a major role, as a central element to the story, or a minor role to support the major characters in the story. Protagonist. The protagonist of a story is another name for the main character. The plot revolves around the protagonist. There may even be more than one main character. In The Adventures of Huckleberry Finn, Huck Finn is the protagonist.In Little Red Riding Hood, the little girl is the protagonist. Antagonist. The antagonist is the character who represents a challenge or an obstacle to the protagonist in a story. In some stories, the antagonist is not a person but rather a larger entity or force that must be dealt with. In Little Red Riding Hood, the wolf is the antagonist.In The Adventures of Huckleberry Finn, society is the antagonist. Society, with its unfair laws and rules, represents the obstacle to Hucks development as a person. Foil. A foil is a character who provides contrast to the main character (protagonist), in order to emphasize the main characters traits. In A Christmas Carol, the kind nephew, Fred, is the foil to nasty Ebenezer Scrooge. Show Your Characters Development (Growth and Change) When you are asked to write a character analysis, you will be expected to explain how a character changes and grows. Most major characters go through some kind of significant growthà as a story unfolds, often a direct result of dealing with some sort of conflict. Notice, as you read, which main characters grow stronger, fall apart, develop new relationships, or discover new aspects of themselves. Make note of scenes in which character changes become apparent or the characters opinions on a topic change. Clues include phrases such as she suddenly realized that... or for the first time, he... Understanding the journey of your character and how it relates to the story as a whole can help you better understand that characters motives and better represent the person in your overall analysis.

Sir Francis Drake Essay Example | Topics and Well Written Essays - 500 words
Sir Francis Drake - Essay Example Sir Francis also paved a way for trade to many other nations, including Far East, which made England a spice trade central point. Participation in trade helped Britain gain more popularity and wealth for a long period. Sir Francis was able to raid Spanish successfully through its ports and carried away much wealth to England. Raid activities made him gain a lot of wealth for his nation which was indirectly supported by Elizabeth 1. Sir Francis was also the first adventurer and captain to sail all over the world. 2He had qualities of a leader, since he was able to influence people into obtaining wealth and raiding nation successfully. He had a known behavior of eliminating people who stood on his way towards implementation of his plans. Sir Francis raided ports belonging to other nations, carrying away gold and silver back to his country. Raiding activities made Britain strong in power at the expense of the other nations. Countries like Portugal and Spanish were highly affected and their economy was left unstable. New trade was established to many countries, which acted as an exit for many surplus products produced in several states. Sir Francis was important to Britain for his achievement in bringing more wealth to the country in terms of gold and silver. This move was achieved through raids executed on specific ports where cargo ships were found. 3He also became important to his nation by enabling it control strategic routes on sea to far areas of the world. He made more victories than failures which gave his country a chance to gain great power. Sir Francis was never a victim of failure in any assignment which was ever undertaken on behalf of his country. He was never held back by conscience in attaining victory compared to other adventurers who would retreat due to their inner self. He attained fame through his enemies and not from Englishmen who walked with him. His uniqueness was also based on experience in plundering which substituted

Team as an Ideal Design of Job Essay Example | Topics and Well Written Essays - 1250 words
Team as an Ideal Design of Job - Essay Example The paper will try examining issues that revolve around the work of the team and their significance in working with the managers. It is possible for managers to create a work unit by just bringing together many individuals with different skills. Before a manager designs a task that they need to be handled, it is always clear that they have a picture of the nature of the outcome they desire. They also have idea on which kind of input is required and what would be the process needed to realize the objective. It is through this understanding that the manger may decide to have a group of individuals to execute the work. This kind of approach has been associated with an authoritarian guidance by some manager. Workers who are involved in a process like this are always denied their autonomy and have very low worker interdependence. The study shows that the productivity of a work force is usually increased when workers have a high sense of interdependence as opposed to when workers are just pulled together to execute certain tasks. It is therefore right to say that team task design is a good design that managers can use to push for results to be gotten but only if the worker interdependence is enhanced. It should not be assumed that team interdependent is the sole mechanism that can be used by mangers to help in utilizing the team and produce successfully. There are some other ways through which teams can be used to realize the objective of an organization. A team as a unit requires some level of self direction and self management to realize certain objective. When teams have control of themselves, then they tend to engage in participatory approach of work, which also relieves the top management from micromanaging the teams and ever getting concerned with small matters that can be addressed at lower levels. It is imperative that mangers delegate duties to the juniors so that they may get

Leadership Plan to Facilitate Prof. Dev. focusing on BrainSMART Essay
Leadership Plan to Facilitate Prof. Dev. focusing on BrainSMART strategies - Essay Example Some of the brain exercises that is necessary for people at different facets of life facing different problems are also discussed. Brain learning system has become an important tool in the hands of educators for increased professional development of the students. Through this system iit is possible to improve concentration, participation, social skills, language ability, ability to express ideas eyc could be improved a lot. In order to use this system, the educators have to be properly trained and should understand the concept behind this. But most of the educators are unaware of this fact and many of them would not like the idea of connecting this to the lesson plans. Research has revealed that it is possible to increase the levels or scores of the student by incorporating this system into the class room instructions.( Chiappetta, 2009). Leadership is a quality, which could be developed by proper brain exercises. This is a quality that require tremendous ability to communicate, understand emotions of the people, control one's own emotions, social interaction, skills for speech and to get the attention of audience. The success in this aspect depends on how brain is processing the intelligence and through proper brain exercises it is possible to improve IQ of a person and thereby his leadership ability (Dickmann & Stanford-Blair, 2002) The brain research has started in full swing after the innovation of technologies for electroencephalograms, positron emission tomography, functional magnetic resonance imaging etc, which have enabled scientists around the world to understand the changes that are taking place in the brain at each and every moment. The brain exercises have been perfected based on such studies and therefore are reliable. A person, whether he is a student or an employee at a lower level or a business executive, he could benefit a lot from brain exercises (Dickmann & Stanford-Blair, 2002). The overall advantages of doing brain exercises could be summarized as follows (Bailey, 2009). It would increase the potential of the brain by improving the span of attention, increase social skills and improve social behavior and it would reduce fight for power. Thus it would help in building bonds with people rather than disrupt it. Most of the mental disabilities could be masked by brain exercises. Different students have different learning style. The teacher should allow the students to adopt their learning style to learn. This is because a student who is learning in his or her own learning style would be able to learn better and the topic would be more meaningful to her/him (Conyers and Wilson, 2005, p.45). Thus it is very important that the teachers should understand how brain affects learning and incorporate their knowledge in the classroom so that the place would be regarded as a safe place by students and would lead to positive development emotionally and socially. There are five different learning styles for any student (Given, 2002), which should be understood by the educators for making them to learn more effectively. They are

The Light Of Sight :: essays research papers
In this universe there are many thing that we cannot explain. Among these many things is light. Light, as far as we know, come in different wavelengths and the size of the wavelength determine what type of light it is. The middle wavelength lights are what gives us the seven basic colors of red, orange, yellow, green, blue, indigo and violet. Beside these visible lights there are the lights that cannot be seen by the human eye. These invisible lights can be grouped into two other groups the long waves and short waves. The first group of waves is the longer wavelength of light including infrared and radio waves. Radio waves, the longest wavelengths, alternate and can be volatile. Arthur C. Clarke said in the essay "The Light of Common Day" that since radio waves fluctuate so much no animal has ever been able to sense them. He goes on to say that if you had an eye big enough to see radio waves your eyes would be millions of times larger than a normal eye. The next longest wave is the infrared light waves. Infrared light is used nowadays to see in the night. Special goggles are designed to pick up infrared light making it possible to see at night. The next group of light waves are the shorter waves of ultraviolet and x-rays. Ultraviolet light, sometimes referred to as UV, is right next to violet and is just beyond sight. UV light is what causes sunburns and can be very painful. In Arthur C. Clarks essay it states that even though UV light is not visible the retina of the human eye reacts powerfully to it. He compare the human eye to a camera and says that a good camera need may types of lenses made out of different types of glass to take a good picture. The human eye has only one lens and cannot possible see UV light. The last type of light is the x-ray. The x-ray is the smallest wave and is used in the medical field greatly to take pictures through flesh of bones. Even though x-rays are very useful they can be very dangerous. They have been know to disrupt radio waves and can poison a human body to the point of death.

Variable naming rules in Visual Basic, Python, and Java
This paper will describe the variable naming rules of three different programming languages. These three languages are Visual Basic, Python, and Java. Each of these languages has different rules that apply to them and some similarities. I will describe the rules and the similarities and differences in the next few paragraphs.The first language and its rules I will describe is Visual Basic. Visual Basic has a few different rules and they are described on Microsoftââ¬â¢s website in a document. This document is called (ââ¬Å"Visual Basic Naming Rulesâ⬠) and they read as such: You must use a letter as the first character.You can't use a space, period (.), exclamation mark (!), or the characters @, &, $, # in the name. Name can't exceed 255 characters in length. Generally, you shouldn't use any names that are the same as the functions, statements, and methods in Visual Basic. Visual Basic isn't case-sensitive, but it preserves the capitalization in the statement where the name is declared. These are the variable naming rules are specific to Visual Basic and are essential to know if you program using Visual Basic.The second language I will describe is Python. This language has a few rules of its own and they are described on a site called programmr.com in an article called (ââ¬Å"Python Variable Naming Rulesâ⬠) and they read as such: Must begin with a letter (a ââ¬â z, A ââ¬â B) or underscore (_).à Other characters can be letters, numbers or _ only.à Variable names are Case Sensitive.There are some reserved words which we cannot use as a variable name because Python uses them for other things. These are: and, del, from, not, while, as, elif, global, or, with, assert, else, if, pass, yield, break, except, import, print, break, except, import, print, class, exec, in, raise, class, exec, in, raise, continue, finally, is, return, continue, finally, is, return, def, for, lambda and try. These are the naming rules for Python and are necessary to programming in this specific language.The third and final language I will talk about is Java. This program is no different than the other two languages and its rules are described in an Oracle document called (ââ¬Å"Lesson: Language Basicsâ⬠) in a sub article called ââ¬Å"Variablesâ⬠and they read as such: Variable names are case-sensitive. A variable's name can be any legal identifier ââ¬â an unlimited-length sequence of Unicode letters and digits, beginning with a letter, the dollar sign ââ¬Å"$â⬠, or the underscore character ââ¬Å"_â⬠. The convention, however, is to always begin your variable names with a letter, not ââ¬Å"$â⬠or ââ¬Å"_â⬠. Additionally, the dollar sign character, by convention, is never used at all.You may find some situations where auto-generated names will contain the dollar sign, but your variable names should always avoid using it. A similar convention exists for the underscore character; while it's technically legal t o begin your variable's name with ââ¬Å"_â⬠, this practice is discouraged. White space is not permitted. Subsequent characters may be letters, digits, dollar signs, or underscore characters. Conventions (and common sense) apply to this rule as well.When choosing a name for your variables, use full words instead of cryptic abbreviations. Doing so will make your code easier to read and understand. In many cases it will also make your code self-documenting; fields named cadence, speed, and gear, for example, are much more intuitive than abbreviated versions, such as s, c, and g. Also keep in mind that the name you choose must not be a keyword or reserved word. If the name you choose consists of only one word, spell that word in all lowercase letters. If it consists of more than one word, capitalize the first letter of each subsequent word. The names gearRatio and currentGear are prime examples of this convention.If your variable stores a constant value, such as static final int N UM_GEARS = 6, the convention changes slightly, capitalizing every letter and separating subsequent words with the underscore character. By convention, the underscore character is never used elsewhere. The Java programming language is statically-typed, which means that all variables must first be declared before they can be used.

Dzudzuana Cave Early Upper Paleolithic Cave in Georgia
Dzudzuana Cave is a rock shelter with archaeological evidence of several human occupations dated to the Upper Paleolithic period, located in the western part of the Republic of Georgia, five kilometers east of the similarly dated Ortvale Klde rock shelter. Dzudzuana cave is a large karst formation cave, with the opening some 1800 feet (560 meters) above modern sea level and 40 ft (12 m) above the current channel of the Nekressi River. Chronology The site was also occupied during the early Bronze Age and Chalcolithic periods, but the most substantial, occupations are dated to the Upper Paleolithic, including 12 ft (3.5 m) thick layer dated between 24,000 and 32,000 radiocarbon years before the present (RCYBP), which converts to 31,000ââ¬â36,000 calendar years ago cal BP). The site contains stone tools and animal bones similar to those found at the Early Upper Paleolithic occupations of Ortvale Klde, also in Georgia. Unit A: ~5,000ââ¬â6,300 RCYBP, 6000 cal BP, Neolithic, 30 flax fibers, five dyedUnit B: ~11,000ââ¬â13,000 RCYBP, 16,500ââ¬â13,200 cal BP: Terminal Paleolithic, blades and bladelets from bi-polar cores; 48 flax fibers, three dyed (one black, two turquoise)Unit C: ~19,000ââ¬â23,000 RCYBP, 27,000ââ¬â24,000 cal BP: Upper Paleolithic, dominated by blades and bladelets, microliths, flake scrapers, burins, carinated cores; 787 flax fibers, 18 spun, one knotted, 38 dyed (black, gray, turquoise and one pink)Unit D: ~26,000ââ¬â32,000 RCYBP, 34,500ââ¬â32,200 cal BP: Upper Paleolithic, microliths, flake scrapers, thumbnail scrapers and double end scrapers, some bladelets, cores, endscrapers; 488 flax fibers, including 13 spun, 58 dyed (turquoise and gray to black), several exhibited cutting; some of the fibers are 200 mm long, others broken into shorter segments Dinner at Dzudzuana Cave Animal bones showing evidence of butchering (cut marks and burning) in the earliest Upper Paleolithic (UP) levels of the cave are dominated by the mountain goat known as the Caucasian tur (Capra cacausica). Other animals featured in the assemblages are steppe bison (Bison priscus, now extinct), aurochs, red deer, wild boar, wild horse, wolf, and pine marten. Later UP assemblages at the cave are dominated by steppe bison. The researchers suggest that may reflect seasonality of use: steppe bison would have inhabited the open steppe at the base of the foothills in early spring or summer, while tur spend the spring and summer in the mountains and come down to the steppes in late fall or winter. The seasonal use of tur is also seen at Ortvale Klde. The occupations at Dzudzuana cave were made by early modern humans, showing no evidence of Neanderthal occupations such as that seen at Ortvale Klde and other Early UP sites in the Caucasus. The site reflects additional evidence of the early and rapid dominance of EMH as they entered into regions already occupied by Neanderthals. Textile Use at Dzudzuana Cave In 2009, Georgian archaeologist Eliso Kvavadze and colleagues reported the discovery of flax (Linum usitatissimum) fibers in all levels of the Upper Paleolithic occupations, with a peak in level C. A few of the fibers in each of the levels were colored in hues of turquoise, pink and black to gray. One of the threads was twisted, and several had been spun. The ends of the fibers show evidence of being purposely cut. Kvavadze and colleagues surmise that this represents the production of colorful textiles for some purpose, perhaps clothing. Other elements that may be related to the production of clothing discovered at the site include tur hair and the micro-remains of skin beetles and moths. The fibers from Dzudzuana Cave are among the oldest evidence of the use of fiber technology, and unlike other examples, Dzudzuana cave offers details about the use of fibers unrecognized to date. The Dzudzuana Cave flax fibers have clearly been modified, cut, twisted and even dyed gray, black, turquoise and pink, most likely with locally available natural plant pigments. Perishable materials, including cordage, nets, wood, and textiles, have long been recognized as an important piece of hunter-gatherer technology in the Upper Paleolithic; but it is a technology that is nearly invisible to modern archaeologists because the organic materials are so rarely preserved. Some instances of cord and textile preservation include Iron Age bog bodies, the Bronze Age Ice Man, and Archaic period Windover Bog pond cemetery; but for the most part, organic fibers do not survive to the modern day. Purposes of Textiles Paleolithic textile technology included a range of plant fibers and a broad variety of basketry, hunting tools and woven materials apart from clothing. Commonly recognized fibers used for textiles include flax and wool from several different animals, but Upper Paleolithic hunter-gatherers might also have found useful fibers from several trees such as lime, willow, oak, elm, alder, yew, and ash, and plants including milkweed, nettle, and hemp. Hunter-gatherers during the Upper Paleolithic used plant fibers and cordage for a number of useful things, including clothing, basketry, footwear, and nets for traps. Types of textiles found or implicated from the evidence in Eurasian UP sites include cordage, netting, and plaited basketry and textiles with simple twined, plaited and plain woven and twilled designs. Fiber-based hunting techniques for small game included traps, snares, and nets. Excavation History of Dzudzuana Cave The site was first excavated in the mid 1960s by the Georgia State Museum under the direction of D. Tushabramishvili. The site was opened again in 1996, under the direction of Tengiz Meshveliani, as part of a joint Georgian, American and Israeli project who also conducted work at Ortvale Klde.

The Age Of Revolution And The European Revolution
The age of revolution was a powerful dynamic age in the European politics and the European Society that started in 1789 and ended in 1848. During this era, radical citizens and reforming governments in Europe changed the existing laws and the ruling structure in a way that created the forms of the existing modern Europe states. The age was very revolutionary as it gave the introduction to new systems within Europe. The era was both an age of destruction as well as a catalyst for growth. Also, the impacts during this age changed the world socially, politically, and economically. The age even from the fact that it was centered in the Franco-British axe, extended around the world in a way that changed the global old regime domination to the current complex and modern world. The age of revolution was marked by six revolutions; this was the French Revolution, the Haitian Revolution, the revolution of the Latin American wars, the revolution of the Greek wars, and the revolutions of 1830 to 1848. The French Revolution marked a period of social and political radicalization. This revolution greatly affected the French and its modern history; the era marked the decline of powerful churches and monarchies that made the rules in the society. The decline in these powerful churched and monarchies, in turn, gave rise to nationalism and democracy. The Haitian revolution (1791-1804) was marked by slave revolt within the French colonies in Saint Dominique.

Mold level control devices and systems Free Essays
Introduction Continuous casting of steel is a procedure with many factors involved. If any of those factors are non controlled it can hold inauspicious effects to both the steel produced and the equipment bring forthing it. This paper will briefly travel over the demands and equipment needed to adequately command the degree of steel in a uninterrupted casting cast every bit good as jobs that arise if non decently controlled. We will write a custom essay sample on Mold level control devices and systems or any similar topic only for you Order Now Reason For Control The steel ââ¬Ës semilunar cartilage ( top of liquid ) needs to be monitored and controlled for a figure of different grounds. The most obvious grounds are to forestall the steel from overruning the cast or from the cast going drained. Both of those instances would ensue in liquefied steel falling onto the equipment below the cast, doing harm and halting of the procedure. Steel over the cast will slop out and it will besides forestall lubrication from come ining the cast pit. In the instance of excessively small steel nowadays in the cast, the sum of clip the steel is in contact with the cast will be excessively short. If the outer part of the steel does non pass adequate clip near the cast walls, a shell of equal thickness to incorporate the internally liquid steel will non be formed. This would do a jailbreak, leaking molten steel and holding production every bit good. If it was merely those two extremes mentioned above, the allowable degree in the cast would be big and merely necessitate a simple method to keep steel degree within that scope. But it has been noticed industrially that fluctuations in the semilunar cartilage degree can hold noticeable effects on the surface quality of the ensuing product1,2. The formation of laps and bleeds on the steel surface every bit good as deepened oscillation markers have been accredited to limitations on lubrication flow caused by traveling semilunar cartilages. Laps and bleeds are proposed to be caused when lubrication is blocked and the outer steel shell is allowed to touch the cast wall1. That contact bonds the two surfaces together doing cryings to organize in the steel tegument let go ofing liquefied steel. Even the cause of lubrication loss can be its ain job. If the limitation is caused by the semilunar cartilage making the scoria rim, the rim can do denting in the steel surface and can be broken off onto the steel surface through scratch ( Fig. 1 ) . The deepness of oscillation Markss formed by the cast ââ¬Ës oscillation is related to the fluctuation way of the meniscus2. Since oscillation Markss are a byproduct of the speed differences between the cast and steel during denudation, a alteration in the semilunar cartilage degree would alter the comparative speed between the two. So, when the semilunar cartilage rises, more steel progresss per oscillation shot which increases the distance between markers but besides increasing the deepness of the marker ( Fig. 2 ) . On the other manus, when the steel degree in the cast lowers, the antonym is seen and the markers are closer together but each is shallower because of it. Equipment To Monitor The basic mold degree control systems relied merely on feeling devices at the cast to supervise the degree of the steel within it. Two chief options for the finding of steel degree are thermally supervising the cast or optical review of the meniscus1,3. The thermic method requires the installing of thermocouples within the cast above the coveted steel degree. The temperature at the thermocouples can be used to find their distance from the liquefied steel. The job with this method was complication in graduating it, since the temperature-to-distance computation would necessitate the thermocouples ââ¬Ë exact distances up the cast and within the cast every bit good as the heat transportation rate through the cast, its chilling rate and the initial temperature of the steel. A presently preferred method is an optical detector positioned above the cast that straight observes the steel degree. Other countries that require monitoring are the usher axial rotations, the tundish, and the province of the tundish-to-mold flow regulator ( either a stopper rod or a slide gate valve ) ( Fig. 3 ) 4. The set projecting velocity of the steel is monitored through the usher rolls below the cast. The tundish is monitored to find the deepness of steel in the tundish since its ensuing metallostatic force per unit area caput will impact the flow velocity into the cast. The place of the flow regulator is required so that the cross sectional country of the tundish-to-mold flow can be calculated. Many parts are needed to interact with each other to travel a flow regulator3. At the regulator itself there are motion limitation forces to see. For slide gate valves both clash with its holder and force per unit area from the fluxing steel can impact motion, while for a stopper rod clash against the liquid steel every bit good as perkiness within that liquid demand to be considered. About all flow regulators are moved by usage of a hydraulic device. The force per unit area within a hydraulic cylinder is non ever of a degree to do motion, so the hold clip to construct up equal force per unit area to travel the flow regulator should be noted. The other beginning of response hold is from the electrical detector commanding the hydraulic system. All electrical switches have a deadband value which is the minimal electromotive force signal needed to trip a response. Taken together, the holds caused from electromotive force and force per unit area build up and get the better ofing clash ca n show about half a 2nd hold between computing machine bid and physical accommodation. Computer Control Methods All the centripetal readings are inputted into a dynamic control system that determines what accommodations are needed to command the steel degree in the cast. The exact type of control system used presently is a closed-loop automatic control regulator ( Fig. 4 ) 5. This type of accountant does non necessitate human input, regulates the end product ( in this instance steel degree ) to a set value, and mentions prior end product readings for future determinations. The accountant is divided into two chief countries of concern: bid response and perturbation rejection3. Command response trades with doing major accommodations to the system to make the programmed steel level3. This is accomplished by executing a mass-flow balance for the mold4. This portion of the accountant modus operandi is dominate when the cast is ab initio make fulling up or when the degree of steel demands to be changed to a new set point. Once the coveted degree is reached in the cast, all that is required of this portion of the control plan is to maintain the incoming volume rate equal to the outgoing volume rate. The outgoing rate is equal to the projecting velocity from the usher axial rotations multiplied by the face country of the casting. The ingoing rate is based on the tundish-to-mold flowing velocity caused by the deepness of steel in the tundish and its corrected flow country. Adjustment is needed for computation of the ingoing volume rate since frictional forces curtailing flow alteration based on flow speed and turbulency. Disturbance rejection trades with minimising the mistake difference between the current steel degree and the mark steel level3. When the steel degree is near to the mark value, the bid response is used maintain the current mold degree while the perturbation rejection everyday Acts of the Apostless to rectify for minor fluctuations in steel degree. These fluctuations from the mark are normally the consequence of nose clogging, but can besides be caused by other things. There are two major methods for minimising mistake, through a formulated response or through an expert system. A expression modus operandi at the simplest contains a relative invariable that is multiplied by the mistake to rectify the end product system4. While this corrects for the mistake it besides can bring forth extra fluctuation in the steel degree, unless a differential invariable is besides used. By multiplying a changeless by the rate of steel degree fluctuation the rectification response is damped and will settle to the mark degree bit by bit. By utilizing this, the mark degree will non be overshoot ensuing in changeless gap and shutting of the flow regulator and seting unnecessary wear on it. Additional expression parts, like a fuzzed control term, can be used to accelerate response4,6. An expert system everyday uses pre-programmed responses for outputs7,8. It takes the input degrees, and based on anterior technology cognition, picks a predetermined action. While this everyday type is faster and simpler to make than a formula modus operandi, it does non hold the same degree of preciseness. Drumhead The surface quality of uninterrupted dramatis personae steel can be greatly affected by motion of the steel semilunar cartilage in the cast. To acquire the best surface quality possible, the fluctuation scope of the semilunar cartilage should be minimized every bit much as possible. Through supervising the volume flow rates into and out of the cast, every bit good as the alteration in steel degree, the steel degree in the cast can be controlled. In add-on, jobs with steel flow into the cast can be corrected for by usage of computing machine modus operandis. Mentions 1. S. Kumar, B. N. Walker, I. V. Samarasekera, and J. K.
