Synthesis of Substituted Quinazolinones

Synthesis of Substituted Quinazolinones 6. DISCUSSION Heterocyclic compounds, widely distributed in nature are very essential to life. They play a vital role in the metabolism of all living cells. With their high degree of structural diversities and broad spectrum activities, they have proven to be one of the most economically useful chemotherapeutic agents. Synthesis of novel heterocyclic compounds with more potent activities, better efficacy and lower toxicity is the need of the day to the modern synthetic and medicinal chemists. In the present work, a total of 90 newer therapeutic compounds with heterocyclic rings like quinazolinonyl isoxazole and thiocarbamoyl pyrazolines were synthesized by conventional heating. In the 1st step, a total of 18 substituted quinazolinones were synthesized followed by 18 substituted acetylated quinazolinones in the 2nd step by acetylation of 1st step compounds. Treatment of various substituted acetylated quinazolinones with benzaldehyde lead to 18 substituted quinazolinonyl chalcones respectively. Further, when the chalcones were treated with thiosemicarbazide and NH2OH.HCl lead to synthesis of a total of 36 compounds with complex quinazolinonyl thiocarbamoyl pyrazolines and quinazolinonyl isoxazoles. All the above synthesized compounds were structurally confirmed by the IR, 1HNMR and mass spectral analysis. After structural confirmation by physical and spectral characterizations, they were evaluated for pharmacological activities like antibacterial, antifungal, anthelmintic, analgesic and anti-inflammatory activities. 6.1 Structural characterization of synthesized compounds Reaction of anthranilic acid and its derivatives bromo, iodo anthranilic acids with aromatic amines (aniline, p-chloro aniline, p-bromo aniline, m-chloro aniline, p-fluoro aniline and p-methyl aniline) and carbon disulfide in the presence of potassium hydroxide in methanol under reflux for 3hr afforded the corresponding 3-(un)substituted phenyl-6-(un)substituted-2-thioxo-4(3H)-quinazolinones 1a-r. Absorption bands in the range 3210-3445 cm-1 and 1505-1590 cm-1 in the IR spectrum of the synthesized compounds (1a-r) indicated the presence of N-H and a thioureide group (N-C=S) in the thioxoquinazolinone system. Strong absorption band in the range of 1600-1690 cm-1 and a medium band at 1100-1290 cm-1 were also observed due to C=O stretching and C=S stretching respectively [66]. The absence of any band in the region 2600-2550 cm-1 (characteristic of a thiol group) indicated that the compound exists in the solid state in the thione form. The 1HNMR spectrum of 2-thioxo-quinazolin-4(3H)-one in DMSO-d6 showed a singlet of 1H intensity at ÃŽ ´13 ppm for the proton attached to the nitrogen at position 1, and a complex multiplet of 14 protons between ÃŽ ´ 6.0-8.8 ppm. All the above results correlate and confirm the formation of thioxoquinazolinone ring system in respective compounds 1 a-r. When compounds 1 a-r treated with acetic anhydride, N-acetylation was took place and acetyl group was introduced at 1st position of the thioxo quinazolinone nucleus and gave compounds 2 a-r. Acetylation was confirmed by the appearance of peak at ÃŽ ´ 1.72 ppm and disappearance of a peak corresponding to NH in between ÃŽ ´ 9.7 ppm to ÃŽ ´ 13.0 ppm due to the protons of acetyl group. Claisen-Schmidt condensation of 2 a-r with benzaldehyde in alcoholic alkali gave corresponding quinazolinonyl chalcones 3 a-r. IR spectrum of the quinazolinonyl chalcones showed a peak at 1670 cm-1 characteristic of à ¯Ã‚ Ã‚ ¡, à ¯Ã‚ Ã‚ ¢-unsaturated keto functional group [255] of chalcones. Appearance of doublets in the range of ÃŽ ´ 6.7-6.9 ppm and ÃŽ ´ 7.44-7.56 ppm, disappearance of singlet corresponds to 3 protons of the N- acetyl group confirmed the 2-propen-1-one moiety of the titled compounds 3 a-r. 5-Phenyl-3-[3’-(un) substituted phenyl-6’-(un) substituted-2’-thioxo-4’ (3’H)-quinazolinon-1’-yl]-1-thiocarbamoyl-2-pyrazolines 4 a-r were prepared by refluxing quinazolinonyl chalcones with thiosemicarbazide in the presence of sodium hydroxide. Disappears of peck corresponds to ÃŽ ±, ÃŽ ²-unsaturated keto functional group of chalcones at 1670 cm-1 and appearance of pecks at 709.92 cm-1, 1067.42 cm-1, 1386.89 cm-1,1517 cm-1 and 3239.62 cm-1 confirmed the thiocarbamoyl-2-pyrazoline nucleus. Appearance of singlet at ÃŽ ´ 8.46 ppm indicated the two protons of thiocarbamoyl group (NH2-C=S) at 1st position of 1-thiocarbamoyl-2-pyrazoline ring [256]. Cycloaddition of chalcones with hydroxyl amine hydrochloride (NH2OH.HCl) gave isoxazoles 5 a-r. Absence of C=O band and appearance of new bands in the range of 1210-1270 cm-1, 1560-1610 cm-1 in the IR spectrum of all the compounds indicated -C-O-N- and C=N of isoxazole ring respectively [257, 258]. Appearance of a peek in the range of ÃŽ ´ 5.9-6.9 ppm in 1HNMR spectrum correlates with IR spectrum data and confirms the formation of isoxazole ring in the respective compounds. 6.2 Biological activities 6.2.1 Antibacterial activity All the titled compounds (1 a-r, 2 a-r, 3 a-r, 4 a-r and 5 a-r) were evaluated for antibacterial activity. The results were given in Table 5.29, 5.30, 5.31, 5.32 and 5.33. In all compounds basic skeleton and the electron withdrawing halogens played a key role in pharmacological activities. Compounds with electron withdrawing F, Br, Cl groups at para position of phenyl ring and electron releasing CH3 group at para position of the phenyl ring displayed maximum activity against Bacillus subtilis 6.2.2 Antifungal activity All the titled compounds (1 a-r, 2 a-r, 3 a-r, 4 a-r and 5 a-r) were evaluated for antifungal activity. The results were given in Table 5.34, 5.35, 5.36, 5.37 and 5.38. In all compounds basic skeleton and the electron withdrawing halogens played a key role in pharmacological activities. Compounds with electron withdrawing F, Br, Cl groups at para position of phenyl ring and electron releasing CH3 group at para position of the phenyl ring displayed maximum activity against Candida species. 6.2.3 Anthelmintic activity All the titled compounds (1 a-r, 2 a-r, 3 a-r, 4 a-r and 5 a-r) were evaluated for anthelmintic activity. The results were given in fig 5.1, 5.2, 5.3, 5.4 and 5.5. In all compounds basic skeleton and the electron withdrawing halogens played a key role in pharmacological activities. Compounds with electron withdrawing F, Br, Cl groups at para position of phenyl ring and electron releasing CH3 group at para position of the phenyl ring displayed maximum activity against Perithima posthuma. 6.2.4 Analgesic activity All the titled compounds (1 a-r, 2 a-r, 3 a-r, 4 a-r and 5 a-r) were evaluated for analgesic activity. The results were given in fig 5.6, 5.7, 5.8, 5.9 and 5.10. In all compounds basic skeleton and the electron withdrawing halogens played a key role in pharmacological activities. Compounds with electron withdrawing F, Br, Cl groups at para position of phenyl ring and electron releasing CH3 group at para position of the phenyl ring displayed potent analgesic activity. 6.2.5 Anti-inflammatory activity All the titled compounds (1 a-r, 2 a-r, 3 a-r, 4 a-r and 5 a-r) were evaluated for anti-inflammatory activity. The results were given in fig 5.11, 5.12, 5.13, 5.14 and 5.15. In all compounds basic skeleton and the electron withdrawing halogens played a key role in pharmacological activities. Compounds with electron withdrawing F, Br, Cl groups at para position of phenyl ring and electron releasing CH3 group at para position of the phenyl ring displayed maximum anti inflammatory activity.

Finlands Education System Essay

â€Å"The Finland Phenomenon† a name given to Finland’s admired education system. It is listed as the most surprising school system in the world. Its success is intently watched by other countries. The assigned video â€Å"Finland’s Education Success† was documented by Tom Burridge of BBC World News America on April 6, 2010. Week four Reading Journal for English 101 was a writing assignment asking students if the system could be implemented in the United States. â€Å"Finland’s schools score consistently at the top of the world rankings yet the pupils have the fewest number of class hours in the developed world. The proof is in the results and Finland has an education system other countries should learn from and envy. The transformation of Finland’s education system began 40 years ago as a key component to an economic recovery plan. The educators had no idea it was so successful until the year 2000, when a standardized test was given to fifteen years old students. The results revealed the scores. The Finnish youth came out on top as the best readers in the world. Three years later the youth led the scores in math as well. â€Å"By 2006 Finland was first out of 57 countries. The Finnish answer to standardized testing has been to only give exams to small groups of students and to trust in teachers. In 1991 the National Board of Education closed its inspectorate. â€Å"Teachers in Finland design their own courses using a national curriculum as a guide and spend about eighty percent as much time leading classes as their U. S. counterparts do. † Finnish teachers have sufficient opportunity to plan lessons and collaborate with colleagues. â€Å"Teachers in Finland spend fewer hours at school and less time in the classroom than American teachers. In 1979 reformers decided that every teacher in Finland earn a fifth-year master’s degree in theory and practice at one of the eight state universities. From that time forward teachers were granted equal status with doctors and lawyers. Teaching programs were flooded with applicants not because the salaries were that high, but because respect made the job so attractive. Pasi Sahlberg a former physics teacher points out â€Å"We prepare children to learn how to learn and not how to take a test†. All children- clever or less so- were to be taught in the same classrooms, with lots of special teacher help available to make sure no child would be left behind. † Compulsory school in Finland doesn’t begin until children reach the age of seven. â€Å"Children learn better when they are ready. Why stress them out? † Finnish culture values childhood independence children get themselves to school by either walking or biking. Upon arrival at school, children remove their shoes to maintain a relaxed atmosphere. Finnish children spend far more time playing outside even in the depth of winter. The children can’t learn if they don’t play. The children must play† The Finnish children are provided with seventy-five minutes of recess a day compared to the average of twenty-seven for U. S children. Finnish schools don’t assign homework because it is assumed the task is mastered in the classroom. Children are also mandated to take lots of arts and crafts and learning by doing. This is a far cry from the U. S concentration on testing in reading and math since the enactment of No Child Left Behind in 2002. The focus in Finland is on the individual child. If a child is falling behind, the highly trained staff recognizes and addresses the issues to meet the child’s needs. Nearly thirty percent of the children in Finland receive some kind of special help during their first nine years in school. The true focus on education is â€Å"equal opportunity for all. † Finnish educators have a hard time understanding the United States’ fascination with standardized tests. â€Å"Americans like all these bars and graphs and colored charts. † ‘It’s nonsense. We know far more about the children than these tests can tell us. Finland has a culture of collaboration between schools, not competition. All schools perform at the same level and there is no status in attending a particular facility. Finland has no private schools and all Finland’s schools are publicly funded. It is surprising to know that Finland spends about thirty percent less per student to achieve their far superior educational outcomes. The people in the government agencies running the schools from the national officials to the local officials are educators, not business people, military leaders or career politicians. The United States has muddled along in the middle of the pack for the past decade. Government officials have attempted to introduce competition into public schools. President Obama’s Race to the Top initiative invites states to compete for federal dollars using tests and other methods to measure teachers, a philosophy that goes against everything the Finnish schools stand for. â€Å"If you only measure the statistics, you miss the human aspect. † Fortunately United States Federal policies continue to move away from the rigid certainties of the No Child Left Behind legislation. The law has set an unrealistic target for one hundred percent student proficiency in every school by 2014. I couldn’t agree more with the Finland approach to education. In order for the United States to come close to Finland’s success a major change would need to occur. A change I believe would take decades to complete. â€Å"The Finns have made it clear, that in any country, no matter its size or composition, there is much wisdom to minimizing testing and instead investing in broader curricula, smaller classes, and better training, pay and treatment of teachers. The United States should take heed. †

When Was Barbecue Invented

Because humankind has no doubt been cooking meat since the discovery of  fire, its impossible to point to any one person or culture  that invented the barbecue method of cooking. Neither do we know when, exactly, it was invented. We can look to several countries and cultures, however, from which barbecue likely gets its roots, like the 19th-century United States or the Caribbean.   Cowboy Cookin The trail hands slogging their way across the American West in endless cattle drives were allotted less than perfect cuts of meat as part of their daily rations. But these cowboys were nothing if not industrious, and they soon discovered these cuts, like the stringy brisket, could be much improved with five to seven hours of slow cooking to tenderize. Soon they became adept at other meats and cuts, like pork butt, pork ribs, beef ribs, venison, and goat. Funny, how this invention of necessity would eventually become a mania in some parts of the U.S., but just try to debate the merits of Kansas City over Texas over Low Country styles of barbecue. Youll quickly see how passionate and obstinate their adherents can be. Island Meats and French Treats Although there is hardly a country in the world whose people dont in some way partake in outdoor grilling of some kind, say the word barbecue to most people and they think America. But that doesnt mean it was invented here, cowboys or no cowboys.  For instance, the Arawakan Indians of the  West Indian island of Hispaniola have for over 300 years cooked and dried meat over an apparatus they call a barbacoa—which is just a short linguistic hop to barbecue. And no discussion of culinary history would be complete without the French stepping in to assert their hegemony. Many assert the origin of the word goes back to Medieval France, stemming from an  Old Anglo-Norman word, barbeque,  a contraction of the old-french expression barbe-à  -queue, or, from the beard to the tail, referring to how a whole animal was speared before being cooked, spit-style, over a fire. But this is all conjecture, as no one is really certain of the origin of the word. Charcoal Instead of Wood For centuries, the fuel of choice for cooking has been  wood, and it is  still preferred among barbecue aficionados, including those who compete in the thousands of contests that crop up in the U.S. each year.  In America, in fact, smoking meats with woods like mesquite, apple, cherry, and hickory, thereby adding extra dimensions of flavor, has become a culinary art form.   But modern-day backyard barbecuers have  Ellsworth B. A. Zwoyer of Pennsylvania to thank for making their lives much easier. In 1897, Zwoyer patented a design for charcoal briquettes and even built several plants after World War I to produce these compacted squares of wood pulp. However, his story is overshadowed by that of  Henry Fords, who in the early 1920s was looking for a way to reuse wood scraps and sawdust from his Model T assembly lines. He snagged the technology to start a briquette-manufacturing company, which was run by his buddy Edward G. Kingsford. The rest is history.

“a Rose for Emily” - 1309 Words

â€Å"A Rose for Emily† Character Analysis of Miss Emily Grierson â€Å"A Rose for Emily† written by William Faulkner, is a story of Miss Emily Grierson, a woman who was born into a wealthy family in the town of Jefferson. She grew up and lived in a huge Victorian home with servants. After the Civil War, it seems that her family’s wealth started to diminish but the Grierson’s were still trapped in the past of their family’s wealth. Emily Grierson’s past and present life is being recalled by a narrator who expresses the attitudes and ideas of the community. The narrator uses phrases like â€Å"We knew†, â€Å"We said†, and â€Å"We believed† to show the towns involvement. The townspeople pity Miss Emily and look at her as â€Å"fallen monument. Miss Emily is†¦show more content†¦Miss Emily is the community’s subject of gossip and speculation, when she starts to take the attention to Homer Barron, a northern Yankee who has come to town on contract to pave the sidewalks in Jefferson.

But there were still others, older people, who said that even grief could not cause a real lady to forget noblesse oblige (the traditional obligation of the nobility to treat the lower classes with respect and generosity)† (Faulkner 792). While Homer may not be the traditional suitor for Miss Emily, she takes to him due to the fact that she no longer has her father around to run anyone off and she is free to court anyone she wants. Emily, though arrogant and stubborn, grows up in a conservative society where puritan womanhood is firmly believed, so she is wel l aware of the power of tradition.

Business Communication Professional and Technical

Question: Discuss about the Business Communication for Professional and Technical. Answer: Introduction Communication is an essential component of the existence of any business relation. The very success or failure of any firm is entirely dependent on how every part of the business organization communicates with one another. For instance, human resource which is pivotal in the operation and coordination of every aspect of the production process must have efficient and appropriately channeled communication systems to ensure that every process runs as expected. Without proper communication, therefore, the organization risks the danger of unproductivity and ultimate shut down. In effect, professional work environments demand effective and ethical business communications between the stakeholders and organizational management, management and the employees and finally among employees themselves. Since in a workplace, high-quality work related documents are part of the organizational structure since they not only formalize the operation but also enhances the professional image of the organiza tion. To this end, the present course has played a significant role in enhancing the learners ability to move from their familiar academic environment to a professional climate with a high sense of confidence. This paper, therefore, highlights the various lessons learned from the six-course modules as well as the assigned weekly journal articles. It provides a highlight of two key concepts on each weekly module, and then integrates the element of the journal article before providing an analysis of the same. The main idea of the article is then synthesized with the two key concepts borrowed from the module in the effort to explicate the whole learning process. Besides, the paper also presents an application of the lesson learned from both the concept and article to real daily living and future career prospect as an organizational manager. Ethical Communication and paralanguage Ethical communication is the art of passing on a message verbally, non-verbally or graphically to be perceived by another person or persons within a given code of ethics. In a professional setting, ethical communication is regarded as the pivotal element that organizes organizational life and processes since it not only coordinates and sustains relationships within the organizations but also provide professional working environment. Accordingly, a good and effective communication must be clear, honest, democratic, logical and respects the intended audience as it reflects the intended purpose or objective. Considering the alignment to the provided set of ethical standards, ethical communication enhances proper relations between the management and the employee. It also promotes good relations between the business organization and the potential clients. As such ethical communication within working environments must in every possible way respect these guidelines for it to convey the inte nded message as well as sustain and coordinate relationships within the organization. Paralanguage refers to any non-verbalized vocal message that is passed during communication such as frequency, timing, intensity, fluency and vocal quality. These elements often have considerable influence the vocal communication specifically how something is said. In effect, compelling ethical communication must take into great consideration of the proper utilization of paralanguage which improve the communication process as well as presentation approach. In the Journal article by Ticehurst and Ross-Smith (1998), the authors review professional communication between the management and the working personnel of different organizations in Australia. The authors argued that proper and effective communication by the Directorate go a long way in ensuring not only proper coordination within the organization but also increase organizational outcomes such as employees job satisfaction (Ticehurst, Ross-Smith, 1998). To this end, the two key concepts ethical communication and paralanguage, as well as the article, provide an in-depth understanding of the importance that professional communication in a workplace. Through the module, I have understood the holistic nature of communication, especially within an organization and its significance in promoting relations between employees. In my current occupation, I will be able to use these concepts to improve my ability to communicate efficiently and ethically to my fellow employees and employers in the effort to ensure proper coordination within the workplace. As such, I intend to use these concepts in the future as an organizational manager to create a link between organizational strategic goals and communication. I will seek to overcome the conception that communication is merely a superficial element of an organization but regard it as a central organizational process that has multi-dimensional aspects. Analyzing the audience and communication apprehension Analysing audience is the act of examining the information of the targeted audience before an oral presentation. Doing an audience analysis is helpful in adapting the intended message to respond adequately to how the audience is expected to respond. The message to the public who is the end-user must in every possible way be appropriate for them, and all the associated communications must strictly target the defined audience. Subsequently, it ensures that there is proper communication between the speaker and the targeted audience. Communication apprehension on its part is a persons level of anxiety or fear which is often associated with anticipated oral presentation to an individual or a group of persons. Although, viewed as an individual trait, communication apprehension is common when one is to provide a presentation in a public forum, especially where a group of people is expecting a good delivery at the end of the session. Accordingly, issues such as novelty of the subject, the le vel of formality or informality of the expected presentation have a big role in affecting a persons communication apprehension. Unfamiliarity with the targeted audience also brings about an increased comprehension apprehension, not until the sense of familiarity along the presentation sets in. This is a similar case with dissimilarity that a presenter has with the target audience. As the perceive dissimilarity rises, the comprehension apprehension (CA) level also increases. In their article, Amogne and Yigzaw (2013) highlight the pervasive problem of communication apprehension, its impact on an individuals oral presentation ability as well as how to eliminate the problem especially among young people. According to the authors, people with high CA will try in every way to avoid communication since that is the surest way of avoiding anxiety or fear he/she has associated with any communication avenue. From the article and the two key concepts, I have learned that before any public presentation it is essential to analyze the target audience in the effort to familiarize myself with the anticipated communication. This is helpful in minimizing the level of CA. In my current job, I will be able to use these concepts as well as the ideas in the journal article to improve my ability to effectively communicate to a mass of people in more professional manner. I will be able to use these concepts in the future as an organizational manager to ensure that I deliver quality presentations to my fellow workers and the stakeholders at large. Written and Verbal business communication Written business communications are those forms of communications that rely on print media in order to move from one party to another without which it is not regarded as so. Spoken business communications, on the other hand, are merely orally or verbally spoken business arrangements. These two business communications are much distinct in many possible ways. Spoken business communications are regarded as ephemeral while written communications are often static. That is to say, while spoken business communications are often fluid in nature in the sense that they can easily be changed, written business documents are static like the case of an email and therefore not easily changed after sending. Moreover, written documents can easily be stored for future references while spoken word can easily disappear unless recorded or transcribed immediately. Business communications often have varying genres which include application letters and resumes, curriculum vitae, reports and business emails. A good mastery of which particular genre is required for a particular business arrangement is essential in order to enhance effectiveness and authenticity of the message being communicated. However, regardless of the form of rendition of the business message, its sense of formality and professionalism should never be compromised in any way. This is because the very formal nature of the means of communication renders the message a sense of authenticity. Poorly done business documents fail to deliver the expected message, and it connotes a lack of seriousness a high level of unprofessionalism. Just like the written business documents, oral presentations must also portray some sense of competency and accuracy so that the quality of the content is not compromised. In their article published in Technical Communication Quarterly Blythe, Lauer, Curran (2014) argued that both spoken and written business communication should maintain professional demeanor although spoken word may have varying levels of deviations. Written business documents on their part must maintain in every possible way the formality and professionalism for them to equate the weight of their message. In view of the article by Blythe and colleagues (2014) and the two key concepts, I will be able to improve my written business communications in a manner that adapt the formality of my position in the workplace. Besides, I will be able to use these concepts in the future as organizational manager in the effort to enhance further my competence and oratory skills as a professional communicator. In the effect, I will be able to provide proper channels of communications for my staffs and fellow employees in my organization. In this way, I will improve the relations between the manageme nt and employees as well as provide an excellent avenue for feedbacks which is essential to an organization. Such feedback platforms will help the organization to keep in check of its progress especially in regards to personnel welfare. Interpersonal Communication: Working Together Intrapersonal communication is the communication that an individual has with him/herself without necessarily making a sound verbally. In other words, this type of communication entails an individuals thoughts, personal conversations, feelings or emotions. Such internal conversations are imperative in organizing one's verbal, interpersonal communications with other people in at the workplace. It enables one to have critical cues that one need to identify while interacting with other people especially professionally. Interpersonal communication, on the other hand, is the communication that takes place between two or more people and is often characterized by the participation of every party in the discourse. Broadly speaking, this type of communication have six different type of interpersonal relationships namely impersonal, professional, intimate, workplace, family and friendship. In a professional work setting, excellent interpersonal communication skills are pivotal in keeping the go od harmony and collaborative nature of an organization which is essential for optimal productivity and job satisfaction. Teamwork, for instance, relies entirely on good interpersonal communication abilities of every employee in a work environment in the effort to effectively work together for maximum output. It is worth pointing out that interpersonal communication capacity is a compressed skill set that keeps the management and their respective staffs and workmates in a healthy working environment that is conducive for everyone. In reference to the assigned journal article by Sigmar, Hynes, and Hill (2012) interpersonal communication within a professional working environment is critical in the sense that besides demonstrating a sense of professionalism, it enhances relationships. In an organization, communication between the management and stakeholders, management and employees, and among employees themselves must be respectful and professional in order to have a good team working towards the same organizational goals. Sigmar and colleagues observed that in order to effectively develop ones interpersonal communication skills, it is imperative to take into account ones strength, weaknesses, skills set and abilities. Again, it is for the good to avoid ineffective and considerably deleterious communication and language in the effort to sustain and maintain a good relationship between people in an organization. Utilization of such offensive language within an organization may attract imposition of organizational sanctions that may have severe consequences on ones personal and professional development. In effect, in my current occupation, I will use these key concepts and the assigned weekly journal article to enhance my ability to understand as well as communicate professionally and relationally with other employees in my workplace. Besides, using these concepts, I will be able to choose an appropriate communication style for every business context and therefore become an excellent communicator. In addition, I will be able to use the concepts in my future career as a manager especially in ensuring harmonious coexistence among my staff members. As the organizations Manager, I will be able to use my assertive skills to resolve internal organizational conflicts in a more professional and relational manner. Academic and Professional Writing Professional or business writing refers to the writing of formal business oriented documents which are designed purposefully for business communication in effect to coordinate people as well as organizational processes. These professional documents are also written to ensure that the organizational processes and operations are run smoothly and efficiently with proper channels of communications and the sizeable window for interpersonal relations. While writing business communication documents, the author often has full control of the entire process before the document is reviewed by other authors or supervisors before the final presentation. In a professional work setting, the quality and authenticity of the written documents must be up to the standard in order to communicate a considerable demeanor of formality. This is to enhance ones professional image as well as uplift organizational image. To this end, these documents often require a high level of accuracy with minimal or no lati tude for error or oversights. This is because simple mistakes may permanently change the course of the history of the business operations of an organization owing to the miscommunication in the documents. This explains why a business or professional documents must be read and proofread by other authors just to ensure that the room of error is eliminated or minimized to insignificance. Academic writing, on the other hand, is the terms used mostly in tertiary level of education, and it refers to the writing of documents primarily to enhance ones learning process and knowledge on a particular subject matter. Academic writings are often used to demonstrate the students level of mastery of subject area since they must do thorough research in order to produce quality written documents. In the institutions of higher learning, students are often given a subject area on which to write his or her paper and therefore, they often have little control of the subject matter under discussion. They are then required to limit their research and analysis within the specified limit of words and given writing standard. These written documents aim at fostering a high sense of professionalism among students making them ready for their future prospective career choices. In their journal article, Yates and Orlikowski (1992) argued that the genres of organizational communications should be viewed as embedded in the social processes rather than as an independent and isolated rational process. In other words, the communication genres within either business organizations or academic institutions should not be regarded in isolation from the daily communication efforts inasmuch a little level of formality and standard is often observed in both instances. In view of the journal article and the two concepts, I will be able to improve my ability to effectively write professional or business documents to an appropriate standard and format. In effect, I will be able to improve my professional communication skills as well as enhance my organizational image. I will be able to use these concepts in the future as an organizational manager in the effort to ensure effective communication between various organizational departments. These concepts will be useful for me to improve the personal relationship with fellow employees as well as ensure efficient and smooth organizational processes. Organisational Communication These are communications that take place within business environments between the stakeholders and the management, management and the employee and among employees themselves. In any organizational setting, there are two types of communication namely, internal and external communication. Internal communication is the employee themselves while external communication involves communication between the employees and the organizations clients. Regardless of the type of communication, the process must be ethical and professional in order to sustain, coordinate and maintain the existing relationships as well as make new ones in the process. Through organizational communications, the employees are able to work as a team to perform a task as a joint force. In a way, proper and effective communications channels within professional settings enhance interpersonal relations at workplace, and the result is optimal productivity and job satisfaction among employees. The management utilizes the defined organizational communicational channels to regulate, control and effectively coordinate the production processes which aim at realizing the organizations objectives and mission. Besides, organizational communication often provides the employee together with their managers and supervisors to engage in interpersonal or social activities that seek to bind them towards one particular goal. As such, providing an efficient and open organizational communication channels within an institution encourages a healthy environment where the employees can personal develop, and so enhance their creativity. It is worth pointing out that organizational communication efficiency is dependent on the existing organizational structure which encompasses how the communication is to flow within the organization. The organizations complexity, its formalized communication channels as well as centralization of the communication systems play a significant role in determining th e overall efficiency and effectiveness of the communication process. To this end, organizational communication within a professional workplace determines to a great length the success or failure of the production process and the productivity of the employees. In the journal article, Tourish (2014) argued that in a leadership position, the most effective panacea for employees underdevelopment and business unproductivity is effective organizational communication channels. The author observed that proper organizational communication, its structure, and channels bring workers plight right before their management and stakeholders who in turn have the power to change their welfare in order to achieve their maximum productivity. Communication should in every way neutralize the traditionally envisioned leadership positions as masters and the employees as slaves but make it possibly accessible to everyone in order to improve organizational productivity. Workers would prefer to work best in environments where they can communicate well with their immediate supervisors and proper channels for feedbacks are also open to them. Excellent organizational communication often tends to break down rigid leadership hierarchy that may perhaps hinder the productivity of the employee. It also encourages efficient the flow of essential communication from one department to another provided there are excellent communication channels within the workplace. Therefore, in my current job, I will be able to use these concepts in organizational communication and the argument in the journal article to improve my ability to communicate professionally but also seek to ensure that working relationship is maintained. Besides, I will be able to use these concepts in the future as an organizational manager to properly coordinate, control the production capacity of the organization with a strong emphasis on the human resource. I will use the concepts to properly coordinate my staffs activities that are necessary for producing system outputs within the organization. Conclusion Effective business communication is considered as the most critical aspect that determines business success or failure. In any business relations, communication is pivotal in ensuring successful employee and customer interaction which result in both customer satisfaction and maximum productivity on the part of the organization. For any business communication to be efficient and effective, it goes beyond mere speech and hearing, but a great sense of ethical considerations must apply. As such communication must be clear, honest, democratic, logical and it must also respect the intended audience. Within a professional environment, a non-verbalized vocal message such as frequency, timing, intensity, fluency and vocal quality must be used during communication in order to enhance the quality of the communication. Again to ensure the message lands well to the target audience as expected, proper and thorough analysis must be done to reduce chances of communication apprehension which is often associated with public speaking or presentation. This applies even in both written and verbal business communication which demands a considerable level of professionalism and formality. This is considered critical especially in light of the sensitive nature that business relation often have in its wake. Like in any communication, effective business communication within professional working environment demands a good sense of interpersonal communication skills that will promote cohesion and proper relation among workers. Besides, to ensure good relations within the workplace, ineffective and considerably deleterious language should be avoided as this may distort the existing relationships within the organization. In the modern day working environment, great sense of formality and professional demeanor is required to ensure effective organizational communication. Needless to say, effective business communication is essential in ensuring proper coordination of different organizational processes that aim to achieve the organizations objective and long-term goals. Moreover, embracing effective and ethical communication also helps maintain the existing working relationships in workplaces. In effect, good communication within the organization will not only improve the employee work relatio ns among themselves but also enhance its productivity. References Amogne, D., Yigzaw, A. (2013).
