Information System Intelligence and Database Technologies

Question: Portray about the Information System for Intelligence and Database Technologies. Answer: Information Management, Data Mining, and Data Warehousing Information the board is characterized as the execution and improvement procedures, arrangements, and methodology for information handling the board. The information preparing incorporates information mining and warehousing. These two are helps in the board of enormous information. Information mining comprise of assortment of colossal measure of data and databases for information the board (Joseph, 2013). It helps in extricating the information valuable on a particular database for facilitating the information warehousing process. Information warehousing is assortment and procedure of information separated from the information mining. It would help in dealing with the far reaching database for supporting the information examination (Han, Pei Kamber, 2011). Components of the arranging procedure, basic administration and administration Components of Data the board, information warehousing and information mining The components of information the executives, information warehousing and information mining are information depiction, organization of information, access and sharing, existing information and capacity and security. Some other significant components comprise of duty, scholarly privileges of property, chronicle, and safeguarding. Every one of these components are answerable for shaping a sync with the information the executives, mining and warehousing (Vucevic Yaddow, 2012). Job of Data Management, Data Mining, and Data Warehousing in Governance The information the board, information mining and information warehousing would help the legislature in different procedures, for example, dealing with the information of the government representatives, helping them in their charging division, planning plans utilizing electronic framework supported projects, and recognizing the non income items for arranging them. The legislature had utilized these innovations for keeping up the database of states (Ruppert, 2012). Components of vital making arrangements for information the board, mining and warehousing The components of key getting ready for information the executives, mining and warehousing are accomplishment of the exhibition focuses for information tasks, expanding the profitability of the activities, accomplishment of the practical rivalry advantage, and fulfilling clients (Roelofs et al. 2013). These components are basic highlights of information the executives, mining and warehousing arranging process. Data the board and data security and confirmation Data the board and data security and affirmation Data the executives can be characterized as the procedure of the executives of data and information (Mahalakshmi Sundararajan, 2013). The data the executives manages the procedure of data the board utilizing any database framework. The security and confirmation is the way toward ensuring outside unapproved access in the database of the data framework. (McNurlin, Sprague Bui, 1989). In any case, the security and confirmation of data framework would bring about expanding the effectiveness of the data the board. The administration and security confirmation of the data joined would bring about compelling data framework (Schwalbe, 2015). Components of the arranging procedure, basic administration and administration Components of Information the board and Information security and confirmation As per McNurlin Sprague and Bui (1989), the components of data the board and security affirmation are secrecy, uprightness, accessibility, utility, and legitimacy. These components are helpful for the board of data framework and support of the security and confirmation of data. Job of Information the executives and Information security and affirmation in Governance The data the board and security affirmation has helped government in making a database for all the private and secret data. The administration needed to manage enormous measure of information for the preparing and designing their activities. This data must be kept made sure about and shielded from any outer access (Spears, Barki Barton, 2013). It very well may be finished by inferring the data the board and security and confirmation. Components of Strategic making arrangements for Information the board, security and affirmation The components of data the executives and security confirmation are security arrangements, structuring of the database, responsibility and conduct (Mahalakshmi Sundararajan, 2013). These components would help in framing key designs for the data the executives and security confirmation. Information Management and Artificial Intelligence framework Information Management and Artificial Intelligence frameworks Information Management is the way toward dealing with the data on an information based framework (Brodie Mylopoulos, 2012). The information based framework helps in dealing with the data. The theoretical information on the information based framework would be useful in shaping and handling of the Artificial Intelligence ideas. The Artificial Intelligence framework is the advancement of innovation for understanding a framework that is equipped for intuition and learning simply like people (Cohen Feigenbaum, 2014). The framework depends on information picked up from throughout the long stretches of innovative turn of events. The information the executives would show the degree of the information administration for the computerized reasoning. Components of the arranging procedure, normal administration and administration Components of the executives of Knowledge Management and Artificial Intelligence framework The components of information the executives are archive stockpiling, disclosure, informing and expertise. These components would help in shaping administration of the information data. The components of man-made reasoning are information portrayal, surmising strategies, creation framework, cosmology and theory. The components are utilized for shaping the union of the data about the man-made consciousness (Chandrasegaran et al. 2013). Job of Knowledge Management and Artificial Intelligence framework in administration Information the executives has helped in building up a deliberate methodology for the administration of the information based data of their activities. The data of the administration database like government forms or salary explanation can be overseen by the utilization of information the executives data framework. The legislature had executed the procedure of the observation utilizing the computerized reasoning in their activities. The computerized reasoning has helped the administration with the dynamic procedure. The sensible thinking and human knowledge in the created framework has helped the administration for settling on better choices (Wilensky, 2015). Components of Strategic arranging of Knowledge Management and Artificial Intelligence framework The components of key arranging are planning research, looking, plausibility, and idealness (Lundquist Trippl, 2013). These components have helped in framing the administration of the information about the man-made brainpower. The information the board includes components like grouping, stockpiling, programming, crude information, and sort of information (Chang, Manohar Wilhm, 2014). References Brodie, M.

Energy Storage Systems for Advanced Power Applications

Vitality Storage Systems for Advanced Power Applications Dynamic The accompanying task contains the subject of intensity transmission frameworks for seaward wind ranches. The three principle sorts of transmission talked about is Line Commutated Converters, Voltage Sourced Converters and High Voltage Alternating Current. Presentation   Electrical Energy Storage innovation is capable in adapting to key qualities of power. One attribute is its capacity to hourly shift sought after and cost. Before long electrical vitality stockpiling will get fundamental in uniting pertinent markets to utilize progressively sustainable power source, to achieve low CO2 levels for Smart Grids Electrical Energy Storage has three principle targets. These are: Electrical Energy Storage brings down power costs by gathering power accomplished during off-top occasions. To improve unwavering quality of intensity supplies. Electrical Energy Storage customers during system disappointments. For instance, during cataclysmic events. To keep up and improve power quality, recurrence and voltage. As a rule, the meaning of Smart Grid is to modernize the power matrix. It includes all perspectives identified with the electrical framework between any point, from age to utilization. Presently that Smart lattice innovation has been executed the matrix has gotten progressively adaptable and intelligent and gives prompt criticism. The Smart Grid will give data concerning the cost of power and the express the force framework can be traded between power creation and utilization to understand a progressively productive and solid force gracefully Electrical Energy stockpiling is huge in the advancement of Smart Grid. Sorts of Energy Storage and Features Electrical Energy Storage Classification   â To arrange electrical vitality stockpiling frameworks the kind of vitality utilized must be thought of. In figure one underneath the capacity advances are classified into; mechanical, electromechanical, compound, electrical and warm vitality stockpiling frameworks. Optional vitality bearers, for example, hydrogen and engineered gaseous petrol are worked to store electrical vitality through electrolysis of water to make hydrogen and methane. Energy components oxidizes hydrogen or methane to deliver power. The mix of the electrolysis power module methodology is an electrochemical vitality stockpiling framework. Be that as it may, the two gases are multi-reason vitality bearers. For instance, the power can be created in a gas or steam turbine. In this manner, they are sorted as substance vitality stockpiling frameworks. Warm vitality stockpiling frameworks are additionally thought of. Most warm vitality frameworks are not the immediate contribution to capacity frameworks. Be that as it may, utilizing the assistance of warm vitality stockpiling the vitality from sustainable power sources can be fortified, which permits power to be created on request. Hot liquid salts in concentrated sun based force plants and the capacity of warmth in compacted air plants utilizing an adiabatic procedure to accomplish proficiency is a model. Mechanical Storage Systems Siphoned hydroelectric, compacted air vitality stockpiling and flywheel vitality stockpiling are the most famous mechanical stockpiling frameworks utilized. Siphoned Hydro Storage Siphoned hydro capacity innovation uses to stores at various elevations. At off pinnacle times water from the base supply is siphoned to the top store. This is can be alluded to as charging. When electrical vitality is need water from the top store streams down to the base supply, which thus controls turbines situated between the top and base repository. The turbines are associated with generators to then create power. This is known as releasing. Siphoned hydro depends on ecological areas. For high and low repositories dams, overflowed mines, other underground pits and the vast ocean are appropriate areas to develop a siphoned hydro vitality framework plant. Right now in the UK there is one siphoned hydro station situated in Dinorwg in North Wales. This is the force station delineated in figure two underneath. Release timeframes can last as long as a few hours to a couple of days. This relies upon the size of the plant. They are seventy to eighty-five percent proficient. A few points of interest of siphoned hydro innovation is the long lifetime and practicability boundless cycle security of the establishment. Disservices are its reliance on geographical conditions and huge land zone utilized. Packed Air Energy Storage Packed air innovation is utilized as a capacity implies because of its attainable quality. Air is compacted and kept in underground structures or over the ground frameworks of vessels or channels. Gaseous petrol is then blended in with the packed air and consumed, which is extended in particular gas turbines. Common underground stockpiling framework areas are caves, springs or relinquished mines. This procedure is delineated in figure three underneath. Warmth can't be discharged during pressure dispersal as it will cool while away. The air should be warmed before extension in the turbine. This is called Diabatic Compressed Air Energy Storage. This technique gives low full circle efficiencies of under 50%. This framework is entrenched with plants having high unwavering quality and are capable at beginning without unessential force. The primary preferences of packed air vitality stockpiling are its enormous limit. The drawbacks the innovation creates is low full circle effectiveness and area limitation. Flywheel Energy Storage Flywheel vitality stockpiling creates vitality utilizing a pivoting chamber and stores its vitality in a quickened rotor. The flywheel is comprised of a pivoting body/chamber inside a compartment. There are additionally bearing and a transmission gadget. The electrical vitality is created by the flywheel by keeping the turn of the body at a consistent speed. The higher the speed the more vitality put away. To work the flywheel is electrically provided by a transmission gadget. On the off chance that the speed lessens, at that point power my by assembled from the framework by the transmission device.ã‚â The rotor of the flywheel is made out of high quality carbon fibers. These are suspended by attractive heading. The rotor can arrive at velocities of twenty thousand to more than fifty thousand fires up every moment in a vacuum fenced in area. The upsides of utilizing flywheels empowers a long-life length, little support, high force thickness utilizes ecologically dormant material and has magnificent cycle soundness. The burdens to flywheels have elevated levels of release to the opposition noticeable all around and bearing misfortunes. They likewise experience the ill effects of low current productivity.

Dark Age Ahead, By Jane Jacobs - 1282 Words

In her novel, Dark Age Ahead, Jane Jacobs discusses why five pillars of society are in danger. These five pillars are families rigged to fail, credentialing versus education, science abandoned, and dumb-downed taxes and self-policing subverted. She goes into detail as to why each of these sections of our society is struggling and is destined for a dark age. However, for the purpose of this paper, I will focus on education and my agreement as to how educational institutions are focusing on credentialing its student instead of educating them.

This is especially true when the cost†¦show more content†¦These numbers can be frightening for students who have to take out loans to finance their education. However, many students do not understand what is waiting for them after graduation. Students are encouraged to pick a su bject to study that interest them; although this is important, students also need to look at the job opportunities available in that field of study. For example, many young students aspire to become teachers, the job definitely has some perks, but finding a full-time job in teaching can be difficult. According to Maclean’s â€Å"67 per cent of education graduates from Ontario’s class of 2009 found themselves unemployed or underemployed in the following year† (Dehaas 2011). When there are little to no job opportunities students begin to feel the pressure and retreat back to what they know, school. Graduate school seems great and all, but sometimes it is not the right track to take. Students accumulate more debt, become more specialized and expect higher pay because of their higher education. The Economist reports, â€Å"In Canada 80% of postdocs earn $38,600 or less per year before tax – the average salary of a construction worker† (The Economist 20 10). Students need to weigh their options before running back to school. It might be best to work at a local restaurant for a year while looking for a job in your career.

Alexander Fleming The Discovery of Penicillin - 1884 Words

Sir Alexander Fleming changed the world of medicine not only in his days but also in the world today. We have the medicines and antibiotics that we have today because of Alexander Fleming. His discovery was much needed in the world and I hate to think where we would be in the medicine world if he hadn’t discovered penicillin. Alexander Fleming was born on August 6, 1881 in Darvel, Ayrshire, Scotland. He was born on Lochfield Farm, which was his family’s farm. Alex was the seventh of eight children.

In 1924, Sarah and Alexander’s first child was born. It was a son named Robert. Alexander’s son would go on to follow in his father’s footsteps within the medical field. Alexander had a commission in the army during World War 1. He was in the Royal Army Medical Corps, and he studied wound infections as a bacteriologist. It was during his study of wound infections that he found that strong antiseptics did more harm than healing on the wounds. He suggested that a mild saline solution would be better. (Brown, 2013) When he returned back home from World War 1, he returned to St. Mary’s and the Inoculation Department. In 1921, while still working under Wright, Fleming discussed that lysozyme, which is present in our body fluids, worked well as a mild antiseptic. This discovery of lysozyme was the first of Fleming’s many discoveries. His discovery of lysozyme led to a great study and discovery on how the body fights off infections. The time came in 1946 where he was finally was named the successor for Wright, and the Inoculation Department was then renamed Wright-Flemin g Institute. (Brown, 2013) Although Fleming sealed his place in history with the discovery of lysozyme, it was his discover of Penicillin in 1928 that started the revolution of antibiotics and sealed his lasting reputation within the medical world.

Computer Assisted Language Learning

Question: Discuss about theComputer Assisted Language Learning. Answer: Introduction Computers and technology has become extensive in schools, colleges and every other educational sector. Now, since language learning has a sense of urgency at present, it has raised the requirement of computer literacy to the level of obligation (Beatty 2013). Language teachers, now a day have started to employ computers as a medium of new pedagogical instrument for teaching foreign languages. This generated the idea of Computer Assisted Language Learning i.e. CALL and this has been proved to influence educational psychology, designing learning materials for teachers through web based instructions and Human Computer Interaction (Golonka et al. 2014). Summary The authors Cynthia White and Hayo Reinders, in this chapter have emphasized the effectiveness of CALL in teaching the foreign language, English and developing the teaching materials for that purpose through CALL. The authors, in the first place, try to identify the unique features of CALL that has provided it an advantageous position over other conventional non-CALL teaching methods. However, the section also highlights some of the major drawbacks of this technology driven language-learning platform. It has been argued in the chapter that language learning in virtual medium takes place in three levels that include theoretical perspective, pedagogical framework and teaching procedure. The supporters of CALL have asserted immense importance to these stages appreciating them as dynamic, iterative procedures in terms of design and execution. According to the scholars reviewed in this chapter, there are numerous advantages of L2 acquisition through CALL; the materials of CALL aid in deve loping computer literacy, communicative skills, building e-community, creating identity, learning in a collaborative platform and mentoring. Besides, the chapter highlights advantages of organizations in using CALL materials as well as several pedagogical advantages of these materials in the acquisition of L2. Perhaps the greatest advantage of CALL is that it can incorporate such features like recording and animation that are not possible to find in the traditional learning concepts. In the second subsection of the chapter two different projects have been discussed where CALL has been utilized; the first one being in a distance education program and the second being a self-access program in online. The first project, the application of CALL materials in the online distance-learning program was more or less a success but in the second one, the need for effective learner training and increasing the number of support staff was felt. However, in both the projects, it was seen that the students interpretation of the tasks and materials had a mediating role between CALL and the students success. Critique of the Reading The chapter reviewing the utilization of CALL in acquisition of L2 takes a strong stand in supporting the widespread usage of this newly emerged technological language-learning program. The chapter in the beginning identifies some of the distinct features of this learning and by discussing relevant pedagogical theories attempt to highlight the potential positive outcomes of this. Due to the difference in platform and in the process of designing curriculum, CALL faces several difficulties in combining theory and practice (Levy and Stockwell 2013). However, the chapter has shown an inclination to negate the importance of developing theory-based curriculum stating that it was not necessary to restrict the instructional design by grounding it on pedagogical theories. However, this approach is highly wrong as pedagogical theories are meant to discover the essential requirements of a student at different stage and helps the instructors to go in depth of the learners psychology (Ushioda 201 3). Moreover, in the CALL format, face-to-face interaction between the teachers and the learners is absent and that the teacher is not physically present to guide the students according to their learning needs. Hence, a curriculum based on pedagogy built as per the needs of students becomes important here, as it would enhance their learning outcomes. On the other hand, the three-level model is indeed effective for the CALL learners, as this would inevitably help them to learn in a systematic way. In this context, agreeing with the authors it can be said that the pedagogical activities have scope to be initiated at any of the three levels of approach, design and procedure (Reinders and White, 2017). Indeed, it is the openness and flexibility of the CALL procedure that has made the online language learning so popular. To discuss about the unique features and advantages of CALL learning, as Loucky and Ware (2016) identifies, it is highly appreciating that CALL incorporates contemporary technological attributes like peer-to-peer networking, messaging and many more to overcome the pedagogical constraints and affordances. Among all other advantages mentioned about CALL in this chapter, some raise questions about their real power to be proved as an advantage. For instance, the author mentions the availability of multimedia technology like online video and information on internet enhances authenticity (Bueno-Alastuey and Lpez Prez 2014). However, all these mediums that have been mentioned here are not formally established as authentic source for studying and hence, the question about their reliability remains. There are other issues with the matter of teacher-student interaction that have been emphasized by the author are also not beyond questions. Undoubtedly, interaction in the language acquisition pr ogram plays a major role but when this interaction and access to internet does not remain in limit, it can create scope for unnecessary deviation for the students (Oberg and Daniels 2013). Among the appreciating features of CALL, the contribution of technology in this format is worth mentioning here. The infinite possibilities that technology has opened for CALL, is worthy to be praised. Especially, the prompt feedback providing aspect is very helpful for the language learners. The parser-based CALL and language processing has the ability to provide potential feedback even prior to the process of language learning (Balushi 2012). This referred section of the book offers a clear advantageous position of CALL, though presented in subdivisions of organizational and pedagogical. The chapter rightly identifies the principal benefit of CALL in terms of access of internet-based materials at anytime anywhere. However, in this case the writers have not overlooked the potential drawbacks of accessing learning materials without the supervision of the educators. As Loucky and Ware (2016) opines that the context of self-access can be deprived of quality or efficiency without the motivation factor of teachers. In addition, the access to students data and progress report has been easier with this CALL format of learning. On the other hand, the authors have highlighted the advantage of sharing learning materials and updating them easily. However, in this context they have overlooked the fact that this unrestricted opportunity to share materials has opened the chances of plagiarism and dishonesty on students part. Another aspect of cost-efficiency has been mentioned quite emphatically as an advantage. Yet, the initial cost of setting up the infrastructure of CALL has not been cited in the chapter. Setting up the technological appliances and framing CALL materials entail a huge amount of cost and this can be an obstacle to the widespread of technology driven language learning (Lin, Huang and Chen 2014). From the pedagogical perspective the authors have highlighted two aspects how CALL enhances the authenticity of the learning materials and how through the educational games, which is a part of CALL course design, developed for the young learners, assist in their learning process (Reinders and White, 2017). Again, this case of authenticity is arguable as collecting corpora to develop dictionaries and even to form the textbook content may not be authentic. However, the writers have put forward an argument on this stating that the learning materials gathered from authentic sources are not necessarily of better quality always. This opinion has considerable logic in it and one can agree with them in this context. Apart from this, the agrreing with Griffiths and Oxford (2014), it can be said that the innovative idea of engaging students in educational games for better learning experience is highly appreciating. Excluding all these advantages and gaps in the learning process through CALL, the best among all is the communication process between two learners, which is highly praiseworthy. The way two students are partnered, where someone interested to learn a specific language is aligned with another student having that language as L1 is of great advantage. This kind of partnering across nationalities and languages is not possible in the traditional language learning program and that it facilitates the students to learn a language with its practical implications. This flow of ideas among the students is undoubtedly an advantageous ground for L2 learners. In case of situated learning, it is indeed challenging for the students as well as for the teachers to develop such situations and plan activities for the learners so that they can gather knowledge from real life situations. In traditional learning medium, creating this environment of situational learning is very difficult for the teachers but in as the authors mention, in CALL, this becomes much easier. This is because the educators need to create exercises for the students only and since this format of learning is somewhat self-reliant for the L2 learners, it is up to them to complete the tasks and activities recommended on their own (Reinders and White, 2017). The aspect of language learning through multimodality is an interesting characteristic of CALL. In the traditional materials, the scope of using multimedia was absent. Knowing the fact that language acquisition becomes better with audio-visual medium and through constant interaction, there is no denial of the fact that CALL remains much ahead of conventional language learning programs. The CALL format enables the instructors to repackage the materials into one mode from the other (Ushioda 2013). The benefit of this multimodality aspect is that the students can easily learn according to their preference of medium. However, the simulations of real world that CALL is able to offer indeed accelerates the pace of L2 acquisition although the authors do not overlook its limited scopes due to technical challenges (Golonka et al. 2014). In this context, there is another benefit of CALL potentially identified by the authors. This entails the non-linearity of CALL presenting the students with opportunity to access information according to their choice of sequence. These are all advantages due to the involvement of technology in this format. However, as this non-linear learning violates the predetermined sequence grounded on pedagogical theories, many scholars like Ushioda (2013), have objected to this suspecting that students may unconsciously misguide them in the absence of an educators intervention. The major advantage that CALL incorporates in its space is the ability to monitor and record the learners progress and their learning behavior in a more efficient and easier way. Since all the monitoring and recording procedures are done mechanically, there are less chances of bias and that the students can also have opportunity to have a reflection on their progress. To opine from the pedagogical perspective, this aspect facilitating ongoing study planning develops the metacognitive awareness of the learners (Reinders and White, 2017). Besides, the CALL form of learning assists the learners to gain control over their leaning program giving them a feeling of empowerment. However, to what extent this control can be allowed is open to questions. In the second subsection, where CALL is shown in practice in two different projects, the advantages and disadvantages of this learning medium are expressed more explicitly. In the Online Distance Foreign Language Teaching program, the writers authentically document how the transfer from face-to-face learning to CALL has been difficult and challenging. Actually, this is the practical side of implementing CALL, which many of the scholars have disregarded in their highly welcoming analysis. Another project completed in University of Auckland offered an online language-learning program empowering the students with self-access. This project along with the one conducted in King Mongkut University of Technology showed the gaps behind planning and its implementation, as according to Levy and Stockwell (2013), the students required more support materials than expected. The realization of CALL in the institutes clearly shows that the apparently thought easy implementation process has faced wit h major failure. In the online self-assessment program of Auckland University, the major challenge became to motivate students to use the online programs abundantly (Reinders and White 2017). Despite efforts and the huge positive response from the students, it became difficult to make them continue with the program. However, the authors lack in providing a solution to this unwillingness in the chapter and only highlighting the problems will not help. Conclusion Having explored the chapter from a critical point-of-view, it can be said that the authors have effectively highlighted all the major areas of benefit that CALL offers though many of the potential drawbacks have been overlooked or missed by them. This critical analysis also picks out the gap that remains between the theoretical concept and the practical implementation of CALL supported by the findings of projects conducted in the second subsection. The chapter has prioritized the matter of practicality in course design over pedagogical perspective. However, apart from all these, the critique of the chapter reveals that not enough concentration has been given on CALL as a language learning program; rather the discussion, at times appears to be general e-learning program. Excluding all these issues, the argument presented on CALL in this chapter has been a successful one. References Balushi, M. 2012.

Micro-payments – Among the most radical alterations in the coming months- not years- is the usage of micro-payment systems from a assortment of fiscal houses. e. g. . Paypal. Visa. WesternUnion. among others. including Bankss. This tendency is facilitated by the W3C working group that approved these protocols and proficient criterions for the interworking. These systems will alter non merely how we carry money but how we value money and believe about purchases. ( See how a purchase of $ 4. 99 feels in a nomadic app shop vs. at Dunkin’ Donuts. ) Payment systems that make it easier to purchase online. coupled with nomadic engineerings will speed up the use of planetary e-commerce applications. 2. Mobile technologies – More people entree the Internet on their Mobile devices than on any other device. We are quickly nearing the clip ( if we are non already at that place ) where designs must be created for the nomadic Web foremost. and for the desktop second. Mobile engineerings facilitate comparing shopping ; with the coming of barcode reader apps and price-comparison databases. a consumer could snarl a saloon codification in Walmart and rapidly cite merchandise reappraisals and monetary values on walmart. com ( or compare monetary values with Walmart rivals ) . Mobile engineerings besides facilitate impulse bargains – particularly with the coming of micro-payments tied to the nomadic device. Just late. Starbucks clients can non merely put an order with their Smartphone. but besides make a purchase. 3. Social media – As Facebook has become the most visited site on the Web. the function of societal media. including Facebook and its local ringers such as Twitter. is progressively of import. Social media sites progressively act as points of entry to e-commerce sites. and frailty versa. as e-commerce sites build evaluation. trueness and referral systems tied to societal media. Group purchasing ( e. g. . Groupon ) is besides deriving mainstream land. with many deal of the day sites viing for an progressively savvy consumer base. but betterments lie in front as the societal facets and user experience are refined. 4. Fulfillment options – I believe that users will desire to hold multiple fulfilments and return options when interacting with a seller: ship to turn to. courier. pick-up in shop. return to hive away. etc. Having many fulfilment options is how clients view their overall client experience. Some companies have made a concern proposition online by being exceeding in service to the on-line channel ( e. g. . Zappos ) . 5. Global handiness – Increasingly. consumers want the handiness to purchase merchandises from foreign sites and have them delivered locally. Thus. currency and imposts will be of turning concern to many on-line retail merchants. Along with this. there will be concerns with local privateness Torahs and limitations on related informations aggregation and storage. 6. Localization – While the tendency is to globalise. what’s frequently more of import is to place. User Centric’s research clearly shows that sites that feel’ local – with proper imagination. linguistic communication. time/date. weights/measures. currency. etc. – resonate far more than sites that seem culturally distant or unfertile. 7. Customizability – Consumers want control. and want to be able to plan the inside informations of the points they purchase. 8. Time-based handiness – Some of the hottest and most successful sites are those that have a time-critical response constituent. Sites like Groupon. Gilt and others capitalize on the perceptual experience of limited-time handiness. Making a sense of urgency thrusts traffic and purchase behaviour.

Marketing Across Cultures Essay Example | Topics and Well Written Essays - 2000 words

Marketing Across Cultures - Essay Example With this manipulation of elements, a firm can achieve its objectives in the market that it targets. The elements of the marketing mix are â€Å"product, price, promotion, and place, also referred to as the four Ps† (Bennet, pp. 44, 2009). The firm does not manipulate all of these elements to a significant degree every time it is marketing across cultures. However, the selections of elements, which require manipulation, are only possible in the light of the characteristics of the culture. For this reason, examples, such as the ones stated below, can help to elaborate this fact. The management of the marketing effort is also highly affected by the differences in the cultures of the firm's different target markets. The four functions of the marketing management are analysis, planning, function, and control (Maister, pp. 133, 1997). The degree of importance which management gives to each function is dependent on the characteristics of the market that the firm targets. For example , the characteristics of a market existing in one culture may emphasize the importance of planning above all the other functions, while a market in another culture may necessitate the control function to be the one the firm invests in the most. Again, the true effect of the culture on the marketing management can only be understood through in-depth analysis and examples. According to a case study, which studied international marketing by shedding light on Ikea’s operations in Shanghai, they learned that â€Å"the company must think globally and act locally in hope of building long-term customer relationships and capturing customer value. In marketing decisions, culture does not hold an ultimate status but still calls for due attention as much as other factors, such as the marketing environment and the company’s strategic plan† (Pan, pp. iii, 2005). This is an example of such a case, were marketing across several different cultures has led to a difference in the marketing elements employed, and will thus be useful in understanding the phenomenon.  Similarly, one can deduce that the strategic management that a multinational company does is on a global scale, following the rules it abides by in any part of the world. Whereas the local marketing strategies are designed locally, depending on the target market and culture of the country of operation (Doole and Lowe, pp. 218-225, 2008). Product: One of the elements in the marketing mix, which is majorly affected by the culture to which it is being employed in, is the product itself.

A Business Research Proposal of British Airways

A Business of British Airways - Research Proposal Example The role of social media is very critical in today’s market, as business are desperate of attracting new customers and retaining the new ones as there is intensified competition in the market share of the customers (Kaplan & Haenlein 2010, 63). The airline industry is one of the most competitive markets in the service sector. Major airline operators in the industry are fighting to not only understand the needs of their customers but also in tracking their level of satisfaction with their services (Prokesch 1995, 109). As a result, the utilization of modern social technologies in reaching the customers has become a fundamental practice to enhance competitiveness among key players in the industry. A key player in the airline industry in the United Kingdom is the British Airways that owns about 47 per cent of UK airline market share (Mills 2003, 17). The purpose of the research study is focusing on the role of the social media on the British Airway Company as part of the company’s Customer Relationship Management strategy (CRM). As a result of the low differentiation of the services offered in the industry, the airline industry has become one of the markets under stiff competition in the service sector. As a result, major firms operating in the sector are adopting devise innovative strategies to improve their relationship with their customers through the Customer Relationship Management systems (Belobaba et al. 2009, par 1). The social media has developed to be one of the most effective and convenient platforms due to its popularity where customers are engaged, and communication is also enhanced. CRM has been related to understanding the needs of the customers and addressing them in a timely manner thus social media plays a key role  in enhancing effective CRM (Verhoef 2003, 33). In regards to the to the intensified competition in the

The Value of Work Experience :: Free Essays

The Value of Work Experience A summer or part-time job pays more than money. Even though the money earned is important, the work experience gained has a greater long-term value when one applies for a full-time job after graduation from school. Job application documents (the application blank and the personal data sheet) ask you to list jobs you have held and to list as references the names of individuals who supervised your work. (Gieseking and Plawin, 1994, 22) As one young person was heard to remark, â€Å"You can’t get a job without experience, and you can’t get experience without a job.† That dilemma can be overcome, however, by starting work early in life and by accepting simpler jobs that have no minimum age limit and do not require experience. Jobs Teens Can Do Begin early at jobs that may not pay especially well but help to establish a working track record: delivering newspapers, babysitting, mowing lawns, assisting with gardening, and the like. Use these work experiences as springboards for such later jobs as sales clerks, gas station attendant, fast-food worker, lifeguard, playground supervisor assistant, and office staff assistant (after you have developed basic office skills). As you progress through these work exploration experiences, try increasingly to get jobs that have some relationship to your career plans. If, for example, you want a career involving frequent contact with people—as in sales—seek part-time and summer work that gives you experience in dealing with people. Hamel, 1989, 10) How to Handle Yourself on the Job Whatever the job you are able to get, the following pointers will help you succeed in getting good recommendation for the next job you seek. 1. Be punctual. Get to work on time and return from lunch and other breaks promptly. 2. Get along well with others. Do your job well and offer to assist others who may need help. Take direction with a smile instead of a frown.

Small Team Group Paper

Paper I recently worked in a small group for my employer. The team included five of us. We had signed up to volunteer to serve at a benefit luncheon for M. S. Our previous general manager had been diagnosed with M. S. And stepped down from her position in order to take care of her health. The luncheon was very important to all of us. We were all of different personalities from five different walks of life. We were all girls. Each group always had that one out spoken person, one who was the caboose, and he other three of us where somewhere in the middle of the two personalities that stood out.One of the major problems we had with this group was that the one girl just loved to gab. I think if she could make a living for talking, she'd be a millionaire. Therefore, she would walk around, which we were encouraged to do, and talk to all those who attended. But she took advantage of the freedom to do so. At the luncheon we had sold well over 500 tickets, that didn't include the people who w alked in and bought a ticket at the door. So with being down one person we began to slip behind.We were running out food because our line of communication to the kitchen to refill was cut off, we had tables that needed clean, guest that needed assistance. Because this girl would run off and disappear we had to pull one girl from one station to pick of the slack, so we were constantly always moving around. Once we were able to find a rhythm and the girl came back we set some ground rules. She was not happy being told what to do since it was volunteer work, but we were there for one reason and it as to help raise money for a good cause.We didn't nominate a leader of the group. We figured we were all grown adults there to do grown adult work. We believed we didn't need a leader. We were able to all speak our minds to one another and agree on rules that needed to be enforced so we were successful. We also were representing the company we were working for at the time and did not want to set a bad example or lose our Job over something so silly. Making sure that our time was successful was our number one priority .Us girls all got along so well and liked each there that we wanted the five of us to continue to be able to work together in a team and represent our company at future events such as the one we were working at. Another goal we had was to make the over all luncheon a success. We wanted to help raise as much money for M. S. As possible so next year more people would want to come out and help support the cause. The communication among our group was great. We all had communicated on a daily basis at work. We would text each other on the weekends.None of us were real close until we started working in the groups gather. We were all honest with each other. I think that because we had an open line of communication and were honest with one another that that's what strengthen our relationship between the five of us. Ever since I worked in a group with these five gir ls, it makes me want to work more and more in groups. Sometimes with the same five girls I started with, and sometimes with new people. I enjoyed getting to know these young ladies, and because of it I have build a lifetime friendship. We did go on working more charity events for the community.Our goals for each and every event were always the same. Be positive, we are the face of our company so we had to be the role model, be successful as a whole, engage with the people, make them want to come back to other events we would be doing in the future. We all took to one another so when we had an opinion about something we were all open for discussion. We never took each others criticism to heart, we often would laugh about it and fix the issue that was at hand. Over all we enjoyed each other's company because it passed the time and made working with a group enjoyable.

Essay Crushed Dreams in The Glass Menagerie - 1194 Words

Crushed Dreams in The Glass Menagerie Tennessee Williams is known for his use of symbols, tension, and irony. Williams uses all of these components to express the central theme of The Glass Menagerie - hope followed by despair. Each of the characters has dreams that are destroyed by the harsh realities of the world. As the narrator blatantly admits, since I have a poets weakness for symbols, symbols are central to The Glass Menagerie (Williams 30). Symbols are merely concrete substitutions used to express a particular theme, idea, or character. One major symbol is the fire escape which has a separate function for each of the characters. This fire escape provides a means of escape for Tom from his†¦show more content†¦Both Laura and her glass menagerie break when they are exposed to the outside world, represented by Jim. When Laura gives Jim her broken unicorn, it symbolises her broken heart that Jim will take with him when he leaves. The unicorn is no longer unique like her, rather he is common now - more like Jim. Therefore, she gives the unicorn to Jim. Just as she gives Jim a little bit of herself to take with him, he leaves behind a little bit of himself with her shattered hopes. Another recurrent symbol used throughout The Glass Menagerie is the use of rainbows. Rainbows symbolise hope and each mention of rainbows in the play is associated with a hopeful situation. When Tom talks about his rainbow-coloured scarf that he got at the magic show, he talks about how it changed a bowl of goldfish into flying canaries. Just like the canaries, Tom hopes to fly away too - to escape from his imprisonment. The chandeliers which create rainbow reflections at the Dance Hall foreshadow the dance between Jim and Laura which instils hope within her. At the end when Tom looks at pieces of coloured glass, like bits of a shattered rainbow, he remembers his sister and hopes that he can blow [her] candles out (Williams 137). Ironically, though the rainbows seemed to be positive signs, they all end in disappointment. Irony is shown mostly through the voice of the narrator.
