What Is Effective Business Communication Commerce Essay
What Is Effective Business Communication Commerce Essay It is hard to imagine a world without communication. From humans to ants, communication is vital for functioning. Hence its importance in business cannot be undermined. According to Murphy et al it is the life blood of any business (Murphy et al, 2009). Without communication it is very difficult to get your point across or to make a difference. To some the skills of communication come naturally while to others it needs a lot of practice and learning. Luckily effective communication techniques can be mastered if one puts his mind to it. Communication has many realms to it. Though ancient communication gave more importance to written and oral, now days, along with that, non-verbal communication has also gained precedence. With the advent of new technologies frequently, the means to communicate is constantly evolving. This makes it essential to keep up with the pace of change. In todays volatile and highly dynamic work atmosphere to have good communication skill is important to survive and climb the ladder of success. It is essential to understand business communication and its practices thoroughly before venturing on to actual practice. Stages of Communication Effective communication can be divided into a few distinctive stages. These stages are not absolute and can change from one situation to another. Every communication starts with an idea that forms inside the sender. The sender then converts this into a communicable message. This can be either oral or written. This is encoding. The sender then picks a communication channel to deliver the message. The channel used depends on various factors like what is the location of the receiver, is there a requirement for a permanent record or is it casual, what is the size of the audience, how soon should the message reach the receiver, how complex is the message etc (Krizan et al, 2008). The receiver at the other end received the communication. This process can be referred to as decoding. Here listening skills and comprehension plays a very important role. If the communication is unclear it is the duty of the receiver to ask the necessary questions and clarify it. If a response is expected from the receiver by way of a reply or action, the receiver has to carry that out. The sender can explicitly ask for a response if necessary. The response is as important as the initial communication. The message send by the sender and the response of the receiver depends not only on the words and medium used but also on the non-verbal aspects of the process. Verbal Vs Non-Verbal Communication Business communication can be broadly divided in to two verbal and non-verbal. Both forms are highly important to make the communication effective. The way these two are handled could make or break relationships. Non-verbal communication generally refers to eye contact, facial expressions and elements, posture, gestures and tone of voice (Stuart et al, 2007). It can also be stretched to include etiquette. Though many times difficult to understand, non-verbal communication is considered to be of great importance in communication and most times it is given more credence than verbal communication. If the person is saying one thing and his expression and body language another, it is most likely that people will go with the non-verbal aspect of the conversation. This is a very common fact and need to be considered and understood while communicating. Again with non-verbal communication, culture plays an important role. What is considered a gesture of goodwill or an acceptable habit in one country may be considered offensive in another. For example chewing gum in public is considered to be rude by the Dutch while it is a common practice of the Americans. Similarly when Westerners consider staying silent during a meeting as rude and a sign of being ignorant, the Japanese consider it a sign of success and respect (Guffey et al, 2010). Indian and Middle Eastern cultures consider the left hand as unclean where as in Europe and USA this is not the case. The list of cultural differences in non-verbal communication is quite long. It is quite impossible to learn them all. What a successful businessman usually does is to read up and understand these differences before a meeting or a trip to a country outside his own. The importance given to non-verbal communication does not make verbal communication any less important. In a highly technologically savvy world a lot of the communication takes place just verbally through letters, faxes, emails and chats. Hence having a good vocabulary and the good sense to use it properly is very essential. Similarly, cultural differences creep in for verbal communication as well. For example, the Americans generally tend to keep their business letters short and to the point and do not favor the use of poetic language, where as the French use a certain extend of poetic language even in their formal letters (Chaney and Martin, 2007). These differences exist from country to country not only in the style of communication but also in formats of letters, emails and other forms of written communication. A clear understanding of these differences will make it easier to infer the written communication more clearly and accurately. In case of oral communication it is highly a ppreciated by people from other cultures if the person is able to at least greet in their local language. While dealing with other cultures it always helps to speak in short and clear phrases and check back with the person with regard to the level of understanding. But any sort of communications effectiveness also depends on the medium used. Communication Medium Just like words and gestures, the medium used for communication plays an important role in the whole process of making it effective. Before selecting a medium for communication it is essential to figure out the importance of the communication and the extent of its reach. A message that has to go to the whole organization cannot be communicated by a face to face discussion. It needs to be done either by means of a group email or memo or though public address. It is also essential to have a mental picture of the reaction of the receiver from the communication. Some things that are sensitive in nature may need to be communicated by a one on one meeting and not through an email. To communicate to the masses, companies generally rely on advertisements. The medium used can be the new papers, television and radio, door to door, billboards or even flyers. This has to be done after a lot of planning and study or else there is very chance the advertisement will not appeal to the public. It is essential to make sure that it does not contain any material that may be offensive to one class of people or which may be considered immoral in one country. The person carrying the message is also of key importance in mass communication. For example, Madonnas hit number Like a Prayer was used by Pepsi in its commercials which aired during family oriented programs. But when the real video, which was highly graphic came out, Pepsi was threatened with boycott and hence had to yank the commercial (Forbes, 2007). Communication Gone South When there is a discussion about effective communication it is also important to get an inkling about things that has not gone so well due to wrongful communication in the business world. When Nardelli took over as CEO of Home Depot, there was almost immediate demoralization of the employees and which in turn led to consumer dissatisfaction and complaints. This was all caused by his communication style which was commanding and which was not acceptable to the new breed of people. He also managed to infuriate the shareholders with his arrogance (Bloomberg Businessweek, 2007). This is a classic example of poor communication skills causing negativity in the business. An American ad company took down a large billboard which was found offensive by African-Americans due to the message in it (Bloomberg Buisinessweek, 2011). These are just two examples of the effect of bad communication. There are many more that have led to people losing jobs, companies losing market share, employee unrest an d even companies going out of business. It can thus be said that effective communication is the essence of every businesss success. There is a great need to have the skills to communicate successfully and if such a skill is not inherent, it is essential to acquire it. This can be done by having a clear understanding of the steps involved, the medium used and learning to used words and expressions in a very controlled and thoughtful manner. Conquering the business world is much easier with effective communication. Resources Chaney Lillian H and Martin Jeanette S. (2007), Intercultural Business Communication, Pearson Prentice Hall.

Streptococcus Pyogenes Overview
Streptococcus Pyogenes Overview The beta-hemolytic bacterium Streptococcus pyogenes formally belongs to the family Streptococcaceae, where it is known to be the most pathogenic bacterium out of its entire genus because of the wide spectrum of diseases it is known to cause. However, Streptococcus pyogenes is a ubiquitous, facultative anaerobic bacterium that can be located in the nasal passageways of some healthy individuals due to its ideal environment for microbes. It is a gram positive bacteria that is classified as a group A Streptococci (GAS) that is unique in its ability to cause a wide range of different onsets of illness in its host such as tonsillitis, scarlet fever, cellulitis, erysipelas post-streptococcal glomerulonephritis, necrotizing fasciitis, myonecrosis and lymphangitis. The name Streptococcus is a derivative from the Greek word Streptos meaning easily twisted or to bend and likewise to pyogenes which is a derivative from the word pyogenic, which is a classification for Streptococci that are compat ible with pus formation. Humans are the common reservoir for Streptococcus pyogenes which is capable of causing an array of different symptoms depending on the direct illness it is inflicting on its host. However, it is commonly known for being the culprit behind Streptococcal pharyngitis (Strep throat), where it can cause a mild to severe sore throat accompanied with a fever, tender/swollen lymph nodes and irritated tonsils. It is highly successful in its fast commute from one person to the next. The transmission can be as simple and innocent as the swap of nasal or throat secretions via airborne droplets or from sharing contaminated food and drinks. Strep throat shows no discrimination in the ages it infects. Although, it tends to be more prevalent in young children. Even though Strep throat is highly contagious it is typically a short lived illness that is easily treated by health care providers with the proper course of anti-biotics. If left untreated or mistreated complications such as rheumatic fever c an arise, which is the bodys over driven immune response to the infection. On the other end of the spectrum Streptococcus pyogenes can cause a more detrimental onset of symptoms with the disease known as Necrotizing Fasciitis (The flesh eating disease). Necrotizing Fasciitis is a rare inflammatory infection that promptly targets the fascia and subcutaneous tissues leaving painful blisters and redness on the surface of the infected areas of skin. The symptoms commonly associated with this disease range from flu-like symptoms, the presence of boil-like blisters, discoloration, infrequent urination and significant swelling of the infected area. It is generally spread through direct contact with open or infected wounds on individuals. Unlike Strep throat, Necrotizing Fasciitis is not as commonly seen or as easily treated. It has a high mortality rate, with 1 out of 4 infected people dying from it. ( SITE). However, healthy individuals who practice proper daily hygiene typically dont hav e to worry about becoming infected with Necrotizing Fasciitis. People who are at a greater risk include those who have had recent surgery, a compromised immune system , abrasions on the skin, diabetes, cancer, have had previous surgery etc. Streptococcus pyogenes is a non-sporing bacterium that is non-motile in nature and can be observed in chains and clumps of cocci that are less than 2 à µm in length, producing impressive sized colonies greater than 0.5 mm. There are several different unique M serotypes that contribute to the different diseases caused by Streptococcus pyogenes. Some of strains of M serotypes include Streptolysin O, Streptolysin S, Streptodornase, Streptococcal chemokine protease, Hyaluronidase, Streptokinase, etc. Streptolysin O is a toxin that works on the cell membranes permeability in order to allow for more adequate uptake of larger charged molecules. Streptolysis Sâ⬠¦Ã¢â¬ ¦ Clinical Significance. Streptococcus Pyogenes is self- equipped with many virulence factors that are highly advantageous in its evasion of the hosts immune response in order to make it every bit of possible to establish a productive infection within its host. Initially lipoteichoic aid (LTA) allow for the bacteria to establish an adhering relationship between the cellular surface or mucosa of epithelial cells.(depending on the area of attachment). Protein F (Fibronectin binding protein) comes in and acts as a strong binding reinforcer between the bacteria and its surface of chosen attachment. However, all the while if the bacterium entered through the mouth it may be encountered with secretory IgA antibody in the saliva trying to counter the effects of the antigens on its surfaces to loosen the bacterium. The successful bacterium than quickly begin replicating and colonizing the appealing greater surface area on the tonsils, causing swollen lymph glands and tissue damage as the bacte rium produces compounds like Hyaluronidase to degrade the mammalian cells. The secretions of bradykinins and chemokines result due to the hosts tissue damage which initiate the process of inflammation. The increase of inflammation as well as the rapid ongoing bacterium replication results in the sequence of many immune cells, specifically being neutrophils, macrophages, T-cells, B-cells and dendritic cells. The swollen glands are a direct result of the T -cells increasingly occupying the tonsils while the appearance of yellow pus in the back of the throat is result of the demise of neutrophils. The M protein along with an outer hyaluronic acid capsule aid the bacteria in resisting phagocytosis. All the while pyogenes has established mechanisms to counter specific responses of the host immune response such as T-cell proliferation, counter against neutrophil extracellular traps (NETs), degradation of IgG,etc.

Platos Dialogues As Educational Models Essay -- Philosophy Research P
Dialogue, Dialectic, and Maieutic: Plato's Dialogues As Educational Models ABSTRACT: Platoââ¬â¢s Socrates exemplies the progress of the dialectical method of inquiry. Such a method is capable of actualizing an interlocutorââ¬â¢s latent potential for philosophizing dialectically. The dianoetic practice of Platoââ¬â¢s Socrates is a mixture of dialectical assertions and questions arising out of his ethical concern for the interlocutor. The Dialogues act as educational models exhibiting how one inquires and learns as well as how one must teach in order that others learn to be participants in (or practitioners of) the dialectic. This is the maieutic art of Platoââ¬â¢s Socrates with which he draws his interlocutors into stating and reflecting upon the implications of their uncritically held opinions. We could say that the real subject-matter of many of the Dialogues is at least as much education in the dialectical process while still respecting the literary form of the Dialogues as exhibitive construction. The lack of philosophical closure that often characterizes many of the Dialogues lends additional credence to this position. The subject-matter of many of the dialogues is, therefore, reflexive: it is about itself in the sense that the tacit lesson (practicing the dialectic) will be remembered after its ostensible subject (some philosophical problem) has ceased to be debated. Dialectic is, then, renewable and replicable as an educational method, using "psychagogy"ââ¬âan instrument of maieuticââ¬âto determine first each studentââ¬â¢s individual needs for guiding him toward understanding. The Dialogues As Educational Models Plato's Dialogues are intellectual, noetic experiences; as dramatizations of communicative interactions, they bring into exhibition... ...ress, 1980.

Manufacturing in Space :: science space manufacturing
Man's capability to leave the Earth offers many new prospects for the future. Asteroid mining, building launch facilities on the moon, tourism, and space manufacturing are only some of the many opportunities that are being considered. There are many considerations which must be examined . For example, in the case of manufacturing in space, economic factors include : can it be done on Earth ? If so, which offers a most cost effective venue?; environmental factors include both contamination of the plant and whatever pollutants may be generated in the manufacturing process. Let us examine some of the advantages and disadvantages of this enterprise. Advantages Why manufacture in space? Space offers many unique conditions which alter the properties of materials manufactured. The two major conditions are lack of gravity and lack of contamination Microgravity Gravity causes properties familiar to all of us. One of which is the separation of fluids according to density. With the removal of gravity, alloys and mixtures of materials with properties incompatible here on Earth can be made, resulting in alloys or mixtures which have completely different properties than those found on earth. Other processes which benefit from a lack of gravity include welding, crystal growth, pharmaceuticals, semiconductors, non linear optic and photonic materials. Contamination: Space is a sterile environment. Sensitive production such as semi conductors and biotech would benefit from not having to use expensive equipment to filter out harmful dust which is so prevalent on the Earth. Disadvantages The major disadvantage to manufacturing in space is cost. Currently all space bound vehicles are government owned. Fee structures for sending materials into space are exorbitant and delivery service is both uncertain and infrequent. It costs approximately $20,000.00 per pound to send materials into space currently. Although NASA's goal is to get the cost down to $100.00 per pound it is not likely that this will happen any time soon. Scheduling also remains a problem. The current shuttle fleet flies about 7 missions per year compared to a goal of once per week.

Léopold Sédar Senghor :: essays research papers
Là ©opold Sà ©dar Senghor Senegalese poet and statesman, founder of the Senegalese Democratic Bloc. Senghor was elected president of Senegal in the 1960s. He retired from office in 1980. He was one of the originators of the concept of Nà ©gritude, defined as the literary and artistic expression of the black African experience. In historical context the term has been seen as a reaction against French colonialism and a defence of African culture. It has deeply influnced the strengthening of African identity in the French-speaking black world. "L'à ¨motion est nà ¨gre, la raision est hà ©llà ¨ne." (emotion is Negro, reason is Greek) "Negritude is the totality of the cultural values of the Black world." Là ©opold Sà ©dar Senghor was born in Joal-la-Portugaise, a small fishing vilage about seventy miles south of Dakar. His father was of noble descent and wealthy merchant. His mother was a Peul, one of a pastoral and nomadic people. Later Senghor wrote: "I grew up in the heartland of Africa, at the crossroads / Of castes and races and roads" The first seven years of his life Senghor spent in Djilor with his mother and maternal uncles and aunts. At the age of twelve, he attended the Catholic mission school of Ngazobil. He continued his studied at the Libermann Seminary and Lycà ©e Van Vollenhoven, finishing secondary-school education in 1928. After winning a state scholarship, Senghor then moved to Paris and graduated from the Lycà ©e Louis-le-grand in 1931. During these years he read African-American poets of the Harlem Renaissance and such French poets as Rimbaud, Mallarmà ©, Baudelaire, Verlaine and Valà ©ry. Among Senghor's s friends were Aimà © Cesaire, with whom he would develope the idea of Negritude, and Georges Pompidou, who later elected President of France. In 1932 Senghor was granted French citizenship. He served in a regiment of colonial infantry and in 1935 he obtained the agrà ©gation degree in grammar. From 1935 he worked as a teacher, notably at Lycà ©e Descartes in Tours, then in Paris at Lycà ©e Marcelin Berthelot. At the outbreak of World War II, he joined the French army, but was captured by the Germans and spent eighteen months in a camp as a prisoner of war. During this period he learned German and wrote poems, which were published in HOSTIES NOIRES (1948). In 1944 he was appointed professor of African languages at the Ãâ°cole Nationale de la France d'Outre-Mer. Senghor's first collection of poems, CHANTS D'OMBRE (1945), was inspired by the philosopher Henri Bergson, and dealt with the themes of exile and nostalgia.

Ready For New Achievements Essay
To begin with, through all the writing assignments that I have written so far, I have showed to have the capacity to come out with good ideas. Thinking about possible reasons of the problem, consequences or even solutions to the topic, are all very important as the first step to begin. For instance, while writing assignment number two, I started with questions to make us think how armed guards may not be prepared to work with children, and I listed detailed examples on how its consequences can affect the kidsââ¬â¢ welfare. In doing so, it can make the readers think profoundly, and realize that there is more to worry about over its negative consequences. In other words, deeply comprehending the topic helps to increase my and the readersââ¬â¢ critical thinking and develop better viewpoints and conclusions. Having good concepts, motivated me to write well-developed writings. At the same time, profound thoughts lead me to overthink about the topic and make me spend more time on my writings. Having a lot of ideas to write about are sometimes not necessary. An example of this situation is my ââ¬Å"Kids With Better Futuresâ⬠midterm writing assignment. Since this was an in class paper, I had to come out with strong and good ideas quicker than usual, but I tend to write some run-on sentences. Moreover, I couldnââ¬â¢t show all the ideas I had in that specific moment; because of the time I spent thinking about my main ideas. For example, I could also have written about my own experience as a child and how my parents have been a huge influence in my academic life, or how my environment and life style might affect the way ââ¬Å"The Westernâ⬠and ââ¬Å"Chineseâ⬠parenting styles work. Lacking several ideas made me feel that I did not completely show my thoughts or even feelings about the topic, which I think is one of my biggest weaknesses. Nevertheless, this 263 ESL class has helped me to learn how I can organize my ideas in each paragraph and create good topic sentences. For instance, at the beginning of the course I did not know the correct order in which I had to write out my main ideas. I used to just write what I had in my mind, without taking into account that I was missing the organization of each paragraph, starting from the main idea, the controlling idea, paraphrase, and examples in the conclusion. As a result, my first writing assignment did not turn out that strong. But now, I know how to properly and correctly construct my paragraphs, and how to focus on each paragraphââ¬â¢s structure to make them look precise and clear. I took advantage of this class, learned as much as possible and I am completely prepared for the following levels.
Factional Distillation of Crude Oil
8. 2. 1 (iv) Fractional Distillation of Crude Oil By Blake Turner ââ¬â Year 11 Fractional Distillation of Crude Oil Introduction Crude oil is the term for ââ¬Å"unprocessedâ⬠oil, the stuff that comes out of the ground. It is also known as petroleum. Crude oil is a fossil fuel, meaning that it was made naturally from decaying plants and animals living in ancient seas millions of years ago ââ¬â most places you can find crude oil were once sea beds. Crude oils vary in colour, from clear to tar-black, and in viscosity, from water to almost solid. On average, crude oils are made of the following elements or compounds: * Carbon ââ¬â 84% Hydrogen ââ¬â 14% * Sulphur ââ¬â 1 to 3% (hydrogen sulfide, sulfides, disulfides, elemental sulfur) * Nitrogen ââ¬â less than 1% (basic compounds with amine groups) * Oxygen ââ¬â less than 1% (found in organic compounds such as carbon dioxide, phenols, ketones, carboxylic acids) * Metals ââ¬â less than 1% (nickel, iron , vanadium, copper, arsenic) * Salts ââ¬â less than 1% (sodium chloride, magnesium chloride, calcium chloride) The Process Fractional Distillation The oldest and most common way to separate things into various components (called fractions), is to do it using the differences in boiling temperature.This process is called fractional distillation. You basically heat crude oil up, let it vaporize and then condense the vapour The various components of crude oil have different sizes, weights and boiling temperatures; so, the first step is to separate these components. Because they have different boiling temperatures, they can be separated easily by a process called fractional distillation. The steps of fractional distillation are as follows: 1. You heat the mixture of two or more substances (liquids) with different boiling points to a high temperature.Heating is usually done with high pressure steam to temperatures of about 1112 degrees Fahrenheit / 600 degrees Celsius. 2. The mixture boils, forming vapor (gases); most substances go into the vapor phase. 3. The vapor enters the bottom of a long column (fractional distillation column) that is filled with trays or plates. The trays have many holes or bubble caps (like a loosened cap on a soda bottle) in them to allow the vapor to pass through. They increase the contact time between the vapor and the liquids in the column and help to collect liquids that form at various heights in the column.There is a temperature difference across the column (hot at the bottom, cool at the top). 4. The vapor rises in the column. 5. As the vapor rises through the trays in the column, it cools. 6. When a substance in the vapour reaches a height where the temperature of the column is equal to that substance's boiling point, it will condense to form a liquid. (The substance with the lowest boiling point will condense at the highest point in the column; substances with higher boiling points will condense lower in the column. ). 7.The tr ays collect the various liquid fractions. 8. The collected liquid fractions may pass to condensers, which cool them further, and then go to storage tanks, or they may go to other areas for further chemical processing.
