Wuthering Heights by Emily Bronte Essay Example for Free

Wuthering Heights by Emily Bronte Essay Wuthering Heights written by Emily Bronte is a 19th century gothic novel. The book is the story of love and twisted relationships with a splash of heart ache and evil. Heathcliff and Catherine the main characters are supported by a range of others whom interact with them to keep them apart. The novel has been widely read and made into several movies. The Masterpiece theater production of Wuthering Heights from 1996 is a good rendering, but there are several differences between the book and the movie. In the book Heathcliff’s character is developed with complicated personality traits. He is brooding, angry, compassionate and loving. The movie on the other hand, Heathcliff is a bit softer not exactly the dark skin gipsy you would be expecting. Tom Hardy the actor portraying Heathcliff gives a modern day performance of a softer and mellower person rather than the dark and broody character of the novel. The book also has a narrator a character named Lockwood. Lockwood is the character Bronte uses to progress the story along. Lockwood rents the Manor House from Heathcliff. He is rather ignorant gentleman, so he is not keen on being within the boundaries of Wuthering heights. The movie does not provide the audience with a narrator; however, it provides the use of flashbacks to progress the story along. Bronte uses ghosts in the book Wuthering Heights they represent Heathcliff’s emotions. For example the ghost of dead Catherine represents Heathcliff’s guilt and shame. In the movie the director uses nightmares, visual effects and music to represent the emotions of shame and guilt. Both allow the audience to understand the feelings of the character. Although two different representations are used the shame and the guilt of Heathcliff is understood by the audience. Both the book and movie convey the character in depth emotional makeup. The physical aspects of the novel and the movie are different. In the novel Wuthering Heights word description of scenery allows the readers imagination to create. In the movie actual locations are used which give a more define and detail oriented landscape. The castle used in the movie is dark brick and dates back to the 17th century and represents gloom. The movie also shows the viewer the gloomy surroundings of Wuthering Heights; giving the audience a visual clue to the emotions of the character. Catherine’s daughters home Thrushcross Grange is portrayed as simple cottage allowing the audience to visualize peacefulness and happiness. The movie doesn’t give the viewer excitement the way the book does; therefore, it doesn’t give â€Å"that† page turning experience. The movie comes across as if Heathcliff is a demented man with a cross to bear not really giving you the background of the story. While the book gives you the detail of the passion and betrayal that created this man. All the characters are more defined and developed because of Bronte’s artistic writing style. The movie being constrained by time and other factors can’t fully envelope the characters of book. In conclusion, I would choose a book over a movie. Bronte’s writing style is something that sparks the imagination and the readers are enthralled by the tale from page one to the end. The movie only can offer a short time of entertainment. I rather have the adventure of a good read coming to know the story and characters over time with the flip of the pages. .

Force Measurment System Based On Strain Gauges Engineering Essay

Force Measurment System Based On Strain Gauges Engineering Essay In this part there will be a use of a strain gauge device which experiences a change of electric resistance when it is strained. Design, build and test a force sensor using strain gauges are provided, as well as development of the appropriate combination of strain gauges with other electrical components to obtain an electric voltage or current representing tensile, compressive or bending strain, together with means of displaying and/or recording its value, is a strain gauge system. Tasks Design and build a strain gauge based force sensor based on a cantilever design or otherwise. Build an appropriate VI that can be used to carry out all tests on the sensor. Experimentally evaluation of the output/force transfer functions of the sensor. Include linearity, hysteresis, sensitivity, accuracy and repeatability in the evaluation. Calculation the expected theoretical output values of the sensor and compression them with the experimental results obtained above. Investigate the effect of temperature on the accuracy of the sensor. Based on this investigation suggest a temperature compensation scheme to improve the performance of the sensor. Build an appropriate VI that takes the output of the sensor and display the result in appropriate units. Part I Explain how the AC Power (wattmeter) measurement is carried out at NPL. Draw a block diagram of the measurement system used. You should include the sources of uncertainties in your discussion. Volts, Amps, Watts, VARs and Power Factor are essential fundamental quantities which must be measured accurately in order to optimize the control and delivery of electric power. Definition of electrical power At a given moment, when a current i travels from generator G to receiver Rin the direction defined by the voltage v delivered by the generator (figure 1), the instantaneous power supplied to the receiver R is equal to product v.i. Figure Generator Receiver If the voltage and current are DC, the mean power V.I is equal to the instantaneous power V.I. If the voltage and current are sinusoidal AC, there is generally a phase shift à Ã¢â‚¬   between the voltage and the current (figure 2). The instantaneous values of voltage v and current (I) have the form: v = Vmax cos à Ã¢â‚¬ °t i = Imax cos (à Ã¢â‚¬ °t à Ã¢â‚¬  ) Where à Ã¢â‚¬ °, the pulse, is proportional to the frequency F (à Ã¢â‚¬ ° = 2à Ã¢â€š ¬F). Figure phase shift between the voltage and the current The instantaneous power has a value of: Vmax . Imax . cos à Ã¢â‚¬ ° . cos (à Ã¢â‚¬ °t à Ã¢â‚¬  ). You must take the average value of this product during a period to obtain the expression of the power provided by generator G to receiver R. This power is called the active power and is expressed by the formula: The wattmeter provide the expression of this product, either by causing a deviation of the pointer in the case of a device with an electrodynamics moving coil, or by supplying a DC current or a voltage proportional to the product in the case of electronic wattcmeters; this current or this voltage is then applied to an analogue or digital display. The existence of a phase shift à Ã¢â‚¬ ¢ between the current and the voltage leads, for AC currents, to the introduction of 3 additional quantities: à ¢-   The apparent power S = Veff . Ieff, in VA (volt-amperes), defining the voltage Veff not to be exceeded (insulator breakdown, increase in core loss) and the intensity Ieff circulating in the receivers. à ¢-   The power factor: When the current and voltage are sinusoidal quantities: à ¢-   The reactive power Q = Veff . Ieff . sin à Ã¢â‚¬ ¢, in rva (reactive volt-amperes). The latter may be directly measured by a wattmeter if for voltage Vmax . cos à Ã¢â‚¬ °t we substitute a phase-shifted voltage of à Ã¢â€š ¬/2, i.e. Vmax x cos (à Ã¢â‚¬ °t à Ã¢â€š ¬/2). The mean product measured will be Vmax . Imax . cos (à Ã¢â‚¬ °t à Ã¢â€š ¬/2) x cos (à Ã¢â‚¬ °t à Ã¢â‚¬ ¢) which is expressed by: Vmax. Imax Q = cos (à Ã¢â€š ¬/2 à Ã¢â‚¬ ¢) = Veff . Ieff . à ¢Ã‹â€ Ã… ¡ sin à Ã¢â‚¬ ¢ 2 Knowing P and Q, we can calculate the apparent power and the power factor: Apparent power: S = à ¢Ã‹â€ Ã… ¡P2+Q2 Power factor: PF = P/S = P/à ¢Ã‹â€ Ã… ¡P2+Q2 Knowing the parameters defined above: active power, reactive power, apparent power, power factor, is fundamental in electrical engineering and enables accurate calculation of the characteristics of the equipment used: yield, load, cos à Ã¢â‚¬ ¢, utilization limits. The wattcmeters used for these measurements are classified in three major families: electrodynamics and electronic. Digital Sampling Watt Meter In NPL the digital sampling AC wattcmeters, which are used for calibration work, each require the generation of sample timing pulses suitably locked to the frequency of the AC which is to be measured. Repetitive waveforms representing the instantaneous test voltage and test current are digitised at equal intervals of time harmonically related to the period of the waveforms. A new NPL standard wattmeter calibrator incorporates improved sample timing generation. It uses a crystal digital oscillator to govern both the sample timing and the AC source frequency. This avoids reliance on timing interpolation uniformity within an input period; only digital frequency dividers are needed. Alternatively, commercial frequency synthesizers can be used, with a common master frequency, to give sampling and signal frequencies. Either alternative allows digital phase control, and reduces the use of special-purpose precision analogue electronics. AC power wattmeter and voltmeters: Figure AC Power Measurement by sampling Power measuring at NPL is based on a digital sampling technique. This works by using a pair of analogue to digital converter (ADC) to take instantaneous samples of the respective voltage and current waveforms involved in measuring by multiplying the specimen pairs, the instantaneous power can be established and by averaging instantaneous over a defined interval the average power of that interval can be arranged. Figure Sampling Wattmeter This technique relies on the execution of the ADC in terms of its exactness and its ability to take samples at well-defined instant in time. To meet these requirements NPL has developed an ADC system based on the fastest shape of ADC, known as a blaze converter. Unfortunately, these devices are of circumscribed resolution and to overcome this limitation they are included in configuration that uses a Digital to Analogue Converter (ADC). This organized whole makes employ the repetitive properties of the waveforms of attention where single round is extremely like to the following round. Figure Phantom Power The computer takes a conjecture at the signal level at a stated moment on the waveform. This digital guess is accurately converted to voltage using the DAC. The guess can then be compared to the incoming signal at the required dot in time and the mistake voltage is converted using the blaze converter and passed back to the computer. Because the waveforms are assumed to be repetitive the computer can improve its conjecture for the next round of the waveform using the mistake knowledge from the former round. In this manner the computers conjecture converges on digital reproduction of the input waveform. This reproduction can then be used for AC voltage, current measuring. Figure NPL ADC Schematic Two of these ADC systems are used for single-phase measuring. They are used in conjecture with transducers that change unlike levels of voltage and current to the working signal levels of the ADCs. In organization to present traceability all of these components require single calibration and characterisation. Uncertainty Contribution Any estimation of uncertainties must start by identifying all significant contributions. There may be several sources of error in a measurement where the magnitude of the error could be quantified. Where these can be identified, they should be corrected such that only the residual unknown component contributes to the uncertainty of the measurement. Using the importation of DC voltage from a higher level laboratory as an example, there will be the following uncertainty components: Calibration Uncertainty Transportation Stability with Time Stability with Temperature Noise Usually the measurement techniques used will ensure well defined conditions and minimize loading effects such that the main contributions listed above will be the only significant ones. Calibration Uncertainty Calibration uncertainty is a significant contribution and is usually reported on the certificate of calibration issued by another organization i.e. the national laboratory. Quite reasonably, the national laboratory is beyond the control of other commercial organizations and there is little that can be done by the customer to evaluate the uncertainty reported as a single  ± value on the certificate. For this reason the calibration uncertainty is usually treated as a type B contribution. The reported uncertainty may vary slightly for each calibration and will usually be at a 95% minimum confidence level. Part II Force measurement system based on strain gauges Introduction A small product based of strain gauge is designed in this part of the assignment, force measurement based on strain gauge. Two strain gauges connected properly on each side of a steel cantilever; these two strain gauges are a part of a resistance combination called Wheatstone bridge supplied by 5V. The output of this circuit connected to data acquisition card through an amplification circuit. A Low pass filter circuit provided. The circuit has been designed and calculated then built on a PCB supplied by power supply device. Moreover the circuit has been tested and practically operated using suitable weights (UK 1 penny to 10 pence); ten coins have been used. Data acquisition card used to pass the results to the computer. LabVIEW software was the tool used for monitoring the results. Strain gauge: As an external forces applied to an object, this will produce a stress and strain. That means the metal object will be compressed and the resistance of the metal will increase, while the resistance will decrease if the metal stretched. By using this feature of a specific metal; force measurement sensor bas been built. This called strain gauge. The design of a force measurement system was based on strain gauges because as the name implies they are used for measurement of strain. The strain gauge is attached to the object by a suitable adhesive, such as superglue as shown below: Strain gauge mounted on component under test Figure strain gauge glued on cantilever  [1]   Strain gauge operation: Generally electrical resistance (R) of a metal wire is proportional to the length (L) and inversely proportional to the area (A) as given by (where à Ã‚  is the resistivity). The change in resistance in a strain gauge of resistance R is nearly proportional to the applied strain. [ref9] Hence: K is constant known as the gauge factor which is the sensitivity to strain. Strain; . The gauges used in this report have K=210 ±0.02 Figure (2) shows loaded cantilever Beam SG 1 SG 2 L F X Figure stain gauge block diagram  [2]   The gauges are glued at a distance (L-X) from the load, a load of mass m and weight mg is suspended from the cantilever beam. The beam has thickness t and width w and is made from stainless steel with a young modulus. The calculated strain due to the suspended mass is. Therefore the relative change in the resistance of the strain gauge is given by: . Wheatstone Bridge The change of the resistance of the strain gauges is very small; so the strain gauges have to be connected in a Wheatstone bridge shown in figure (6). The gauge glued on top of the beam is in tension, the gauge glued underneath the beam is in compression, hence strain causes equal and opposite resistance changes in the gauges. By using two gauges the effects of temperature variations on the gauge resistance are cancelled. The bottom end of the bridge circuit is connected to the ground, the circuit is powered by the bridge excitation voltage VEX applied to the top side of the bridge. Figure Wheatstone bridge  [3]   If the strain increases the resistance of Gauge One from R to R + then the resistance of Gauge Two is decreased from R to R . Hence the voltage VG is given by: To balance the Wheatstone bridge the Zero Adjust resistor is adjusted to produce a voltage of VADJ . [ref11] Therefore the output voltage V0 of the Wheatstone bridge is given by: Substituting Then: Circuit design details: Figure Circuit design This circuit is designed and built by a team of three students; and its a number of stages as shown in the block diagram below: Two strain gauges connected on a Wheatstone bridge.

Chart 1. The relation between the mass and O/p voltages Second Stage: In this stage an amplification circuit is needed in order to increase the output voltage to a range of 0 10 v as an input to the data acquisition, INA126 OP AMP has been used with a gain resistance of around 80 ohms to get a 1000 amplification ratio, the following figure show the op amp circuit diagram: Figure Op amp circuit diagram According to the data sheet, and from the table shown above the gain of the circuit can be adjusted by varying the Gain Resistor RG. The gain 1000 needed could be done by using or adjusting the gain resistance RG to be 80.4 à ¢Ã¢â‚¬Å¾Ã‚ ¦ (variable resistor has been used). And the following calculations proves the value of the Gain Resistor RG Since; So; Third stage: Figure Low pass filter circuitAs show in circuit diagram, an RC filter with a components of C= 22uF and R = 10 k ohms. The calculation below shows that this filter values is above the maximum frequency of the expected values from the dc components and to guarantee to get rid of the voltage spikes.

Self evaluation During working on this mini project I have learn a lot according to sensors application specially strain gauges application, and how we could make use of the sensors and how to design a circuit by choose the suitable components as well as improving the output results of the circuit. With the help from the tutor Dr Ahmed we succeed to design and built the circuit. The team which I was involved to do the work with was very good as very accomplish to finish the work as soon as possible. Working on teams has so many advantages as the work would be split to save the time. The designing and the building for the circuit didnt take much time, by the time we finished the design we started to take the measuring and the readings for the outputs. Working on new software like the LABVIEW was very challenge because its the first time for me to get use to this software and a very hard work has been taken to carry some tutorials and know how the software is work. As this software is very wide in use and has everything that the engineer can have the benefit from the use of such amazing software. Conclusion A mini project has been designed and built based on strain gauge trying to perform what it is regarded as basic function like measuring the weight. Stain gauges are quite simple in design. The circuit diagram of the design was designed in the MULTISIM electronic workbench software. All components were calculated to get suitable values as well as a typical calculation has been done for the results. The measurement values compared with the calculated values and a very small different was provided as this is expected and acceptable. Lapview tool was the best software to simulate the output of the circuit where the output can be clearly achieved as well as we could multiply, divide and/or add factors to the output results value.

TO STUDY THE HEAD HUNTING RECRUITMENT PROCESS IN MOTHER DAIRY. INTRODUCTION Indian Dairy Industry: A Profile Indian Dairy’s production level is expected to be tripled by the next 10 years in the view of expanding potential for export to Europe and the West. In the coming years WTO regulations will come in to force in all the developing countries which are among big exporters today. India is the lowest cost producer of per litre milk in the world. Because India is the lowest cost producer of per litre milk in the world, therefore Multinational companies are planning to expand their activities in India. Many milk producers have obtained various certificates for good quality standard from the authorities, which help them to market their product in the foreign market in the processed form. Business Environment Of Dairy Industry India had an acute shortage of milk but gradually it has transformed to the world’s leading milk producer over the span of three decades. This phenomenal success was achieved because Government of India had started this initiative called â€Å"Operation Flood â€Å"and it intensely focused on dairy development activities. In that initiative urban markets were linked to rural milk shed through the development of a network of village cooperatives for procuring and marketing milk. Emerging Situations In India, Dairy is currently the top ranked commodity. Dairy Sector hold a strong position in the GDP, but still it receives less Government funding than the agriculture sector. Since, the population is growing and with that the national income of the people are also growing, they are becoming health conscious and the demand for milk is also growing, therefore this is a serious matter because of the slowdown in the growth of ... ...ficiency and spread its entire work force. They focus more on providing a rigorous training facility to the young recruits so that they are well prepared to face the competitive world. Mother Dairy primarily focuses on the middle class families because they have a strong value system, so they have that urge of learning new things and to work with full dedication. Since, Mother Dairy has moved on from the Transactional HR to Transformational HR that’s why it has been visiting more to various recognised and prestigious campuses for recruiting young talents. Mother Dairy also provides opportunities to young emerging students from various campuses to work with them in the form of summer internship and live projects. By doing this internship’s and projects the students get very good exposures regarding how the real live corporate world is and how it functions.

Mobile Commerce in Developing Countries Essay

Mobile Commerce or M-commerce as it is more commonly referred to is simply the ability to do business electronically without any physical limitations or barriers. This is more popular with the use of smartphones today and other mobile devices. After researching several journals and articles, it is obvious at this point that there is no standard definition of the term â€Å"Mobile Commerce. † Many authors and writers have coined phrases and come up with definitions that are similar to each other; the general idea is similar but the words in the different definitions vary somewhat. However, one acceptable definition is used and this comes from Liang and Wei (2004), â€Å"M-Commerce generally refers to the use of wireless devices (particularly mobile phones) to conduct electronic business transactions, such as product ordering, fund transfers, and stock trading† (p. 7). M-Commerce was formed as a result of the Internet and mobile computing coming together to create a new business area. The benefits of Mobile Commerce are almost endless and a few will be discussed later in the analysis. However, the focus of this paper is the emergence of this trend in developing countries with emphasis on Africa- Nigeria to be precise. The population of Nigeria is over 150 million boasting one of the largest markets in Africa. Akpan-Obong (2009) states that â€Å"Nigeria is a major actor in the Information and Communication Technologies (ICT) sector in Africa, Nigeria has so far recorded significant achievements in ICT utilization, and has recorded higher growth rates in the penetration and diffusion levels of ICT† (p. 208). With Mobile Commerce rapidly taking over the business world, it is important to gain an understanding of how the so called major actors are fairing on the playing field hence the emphasis on Nigeria in the topic of Mobile Commerce. Article Summaries Liang (2004) and Akpan-Obong (2009) in their separate articles introduce the concept of Mobile Commerce and present generally accepted definitions of the term. While Liang focuses on the likely successes and failures of M-Commerce applications, Akpan-Obong specifically suggests electricity and infrastructural inadequacies as the reasons for the underutilization of M-Commerce in Nigeria. Greengard (2008) goes on to discuss the general impact of mobile phones on the world as a whole. He talks about the development opportunities that the presence of mobile phone technologies has created with the transformation of commerce, banking and healthcare. In his article, he states that the most profound changes and biggest dividends are being realized in developing countries. Formulation of a series of hypotheses from a research model developed by Peter, Philip and Victor (2005) identifies some of the factors affecting the use of mobile ICT in the least developed countries. Ayo and Agboola (2006) delve into the uses of M-commerce in Nigeria and how this technology is becoming widespread in the country. Solutions are also offered to deal with the issues of underutilization of the technology. Generally, these articles discuss the current practices and also anticipated future implementations of M-Commerce. The Internet, which is a form of electronic commerce has been in existence for years but it has been difficult to cover as much of the market as it could especially in some parts of the world where amenities like a computer are not only unaffordable but considered a luxury. With the emergence of mobile phones, â€Å"an important fact to consider is that M-Commerce is gaining relevance because the penetration of mobile phones is much larger than the penetration of Internet access (Duffey, 1998) in most countries. Greengard (2008), highlights a few of the relevant uses of this technology: â€Å"Although mobile phones have already transformed the more affluent nations, they are ringing up some of the most profound changes- and biggest dividends- in developing countries. Today, people are using mobile phones to track crop prices in Kenya and manage micropayments in the Philippines. They are tapping into these devices to handle healthcare information in Nicaragua and oversee bakery orders in Nigeria† (p. 17). Gone are the days when Africa as a whole was considered backward and inconsequential when it came to matters of technological advancements, infrastructure and amenities. Like most developing countries, Nigeria in particular has not yet implemented M-Commerce on a full scale. However, the trend is beginning to emerge with the appearance of mobile phones in every nook and cranny of the country. Now, unlike before, devices like mobile phones are no longer seen as sacred or only for the rich and famous in society. Rotberg was spot on when he stated, â€Å"it is the first time in the history of technology that social class and geography are largely irrelevant† (as cited in Greengard, 2008, p. 18). Almost anyone who is of talking age owns a cell phone in Nigeria. From the executives at the renowned industrious firms, the students attending public schools who cant even afford to buy textbooks and even the farmers in the villages and rural areas; the fishermen selling fish at the local market and even the housewives who grow vegetables and cultivate livestock in their backyards. Owning a mobile phone is no longer considered a luxury and does not cost an arm and a leg like it used to only a few years ago. This singular reason that the phones are now easily affordable and available for purchase by every Tom, Dick and Harry is what has fostered the emergence of Mobile Commerce in Africa, Nigeria to be precise. With the mobile phones gaining more popularity with the people in Nigeria, so also has the technological benefits been exploited. The wireless handheld devices have orchestrated the use of e-banking services in Nigeria. According to Ayo et al. (2007), â€Å"virtually all the 25 banks that survived the recent capitalization exercise engage the use of ICT as a platform for effective and efficient delivery of banking services. Consequently, electronic cards, Internet banking and mobile banking services are gradually being introduced. However, M-Banking activities are limited to mobile finance information, download or ringing tones and music as well as telematic services, particularly, vehicle tracking, theft protection and emergency services† (p. 13). As more and more advancements are pursued, banking will become not only flexible but also more convenient. Customers now have the luxury of checking their bank accounts on their mobile device without having to take a trip to the local branch of their banks nearest to them. They also enjoy the comfort of immediacy, information at their fingertips. The banking sector is one of the first and more important aspects of Mobile Commerce that has emerged in Nigeria. However, there is also much hype about the little things that are being derived from this technological advancement. Ayo et al. (2007) states emphatically â€Å"the success of M-Commerce has partly been due to developments in mobile communication techniques. Cellular networks were originally designed for voice-only communication. To support M-Commerce transactions, which are data based, there has been an evolution of these networks from analogue to digital and from circuit switched to packet switched networks. Today a number of these mobile communication technologies are available† (p. 11). Some of the strengths of Mobile Commerce in Nigeria are attributed to the GSM operators and the services that they render to their customers. The three major operators are MTN, Celtel and Globacom. Their services include: Voicemail, WAP services, SMS, customer services, call forwarding, international dialing, Celtel mobile office, faxmail, roaming, customer care and Broadband Internet Access that offers Broadband Internet to residential users just to name a few. These services allow customers to derive utmost satisfaction from the emerging trends in the advancement of Mobile Commerce. In his article, Greengard (2008) talked about one incidence in particular. â€Å"A Nigerian baker started taking orders for cakes via SMS and quickly expanded his presence beyond his immediate neighborhood. He experienced a 30% increase in sales† (p. 17). Many small-scale businesses are now enjoying the benefits of this technological advancement and they are using its features to broaden the scope of their businesses and gain competitive advantage over their competitors in the industry. If not for anything else, the customer relationship that exists between the business owners and their customers has been strengthened by the ability of the owners in providing their services directly to the consumers via these mobile handheld devices. The emergence of Mobile Commerce in Nigeria has brought with it both advantages and disadvantages. As with the mobile banking, of course it is fast, convenient and nowadays very affordable, there is also the threat of security and the complex systems and expertise needed to run some of the programs. There is a gap between those who are more technologically savvy and the layman who grows crops on his farm. This gap in knowledge does not allow the features on some of these hand held devices to be fully utilized. The phones being so affordable that even the most basic of the devices could probably browse the Internet assuming all the features are purchased, makes it likely that the phones are being underutilized to the most of its capabilities. Most senior management and more well to do individuals are more concerned about the security of their transactions over this mobile devices. Research by Agboola (2006), revealed â€Å"38. 2% of the respondents considered security as a major threat, while 4. 3% and 5. 4% considered complication of services and cost respectively as other factors† (p. 3). Apparently, the cost of mobile telephone service is higher in Nigeria than other African countries so it only reasonable that the cost of this service would be a major threat to Mobile banking as a whole. Another threat is the unavailability of basic infrastructure to support this system such as electricity, among others. The lack of electricity as a basic infrastructure in Nigeria has a ripple effect because it affects every device that makes up the system. Without electricity, individuals cannot charge their mobile phones when the battery is depleted. This in itself, defeats the purpose of Mobile Commerce, as there is no fulfillment in owning a phone when you cannot use it when you want to. The systems in the banks that perform the updates to customer accounts and provide information to the customers would also shut down as a result of lack of electricity. Automated Teller Machines (ATMs), which are one of the first occurrences of Mobile Banking in Nigeria, would have to be shut down as well. With all the features of the mobile phones these days, it is only a matter of time before the developing countries of Africa begin to enjoy all of the benefits that countries like America are enjoying now. Although, seeing as how the advancement in America has not come to a halt, it is more than likely that developing countries would always play catch up. However, countries grow at different paces so it is only wise to perform according to the capabilities of the systems set up in the country until it can withstand the test of time. Synthesis Mobile Commerce as a concept has a lot of prospect for patronage dependent on the available services. First of all, there were no mobile phones at all in a country like Nigeria and then mobile phones were introduced and the craze cannot be contained. Now, the monumental growth of mobile devices all over the world, with over one-third of the world population having access to it has given prominence to M-Commerce. With technological advancements emerging everyday in different areas and industries, Mobile Commerce can only get better as more provisions are made to handle the loop holes and reduce the threat that are presently facing the market. There would most likely come a time when Mobile Commerce is not only the fastest way of doing business but the most common, the most trusted and also the safest. It would soon become a way of life. According to Peter et al (2005), â€Å"the country had experienced a phenomenal growth from a teledensity of 0. 49 in 2000 to 25. 22 in 2007. This trend has brought about a monumental development in the major sectors of the economy such as banking, telecoms and commerce in general† (p. 140). Nigeria, being the fastest growing telecoms nation in Africa and the third in the world, it is almost inconceivable to imagine how much is yet to come by way of technology and other infrastructure. Today, African countries may be struggling to hold their weight in the area of technological advancement in comparison with more advanced countries like the United States. Tomorrow, the tables might just be turned. One can only wait and see, behold the future!

Essay on Hang Kang

Essay on Hang Kang Essay on Hang Kang Essay on Hang KangMuch of the work is autobiographical, in that Kang Hang places himself in his narrative of captivity. How does Kang Hang see his position in relation to ChosÃ… n society and the wider world?  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Hang Kang narrative is autobiographical in its essence. At the same time, he conveys the story of his captivity from the perspective of a Korean, who was forced to move to Japan. The forced migration to Japan as a captive of Japanese has changed the worldview of the author. To put it more precisely, he has broadened his eyesight during his captivity in Japan but he has preserved his Korean identity and neo-Confucian views and beliefs. In such a way, Kang Hang viewed himself and his position in relation to Choson society and the wider world as a representative of Korean culture, who stood on neo-Confucian ground and broad philosophic views due to the better understanding of Japanese culture and society. In such a way, the narrative of Hang Kang is the quintessence of Choson culture, neo-Confucian ideas and broad philosophical view on Japan, Korea and the role of the author as the Korean spy and neo-Confucian philosopher spreading the teaching in Japan.  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Hang Kang was devoted to his community and remained Korean, even when he was captured by Japanese. From the beginning of the book and until its end Hang Kang emphasized his belongingness to Choson culture. He always remained Korean and attempted to preserve the cultural identity, which was his native culture. In such a way, it is quite natural that he develops the narrative from the standpoint of a Korean, who was captured and forced to move to Japan as a captive. For example, at the beginning of the book he describes horrors of the invasion of Choson region by Japan. The author focuses on details and horrors of the war, which he describes as the invasion. Remarkably, he fails to understand reasons for the assault and can not explain why Japanese attacked Korea. The lack of understanding of motives and reasons of Japanese was typical for Koreans, because they did not know motives of Japanese. This was the result of the lack of knowledge of Japanese culture. Japan remained terra incognita for Koreans and they could not understand Japanese people and motives of their actions.Even when he was in Japan, he believed he was serving to his king. The work on his narrative involved observations and study of the lifestyle and culture of Japanese,   specificities of their political system, military and social life. In such a way, Hang Kang remained devoted to his fatherland and he viewed himself as a sort of spy in Japan serving to interests and needs of his people in Korea (Turnbull 71). He always remained the outsider in Japan and he did not want to become Japanese or assimilate into Japanese culture. Japanese culture remained the culture of a different culture and Hang Kang has never associated himself wit h Japanese or Japanese culture. Japanese culture remained a foreign culture for Hang Kang as a captive of Japanese but he always remained Korean and could not accept Japanese culture as his own. In fact, he attempted to study Japan and understand Japanese culture, society, the political system and military to communicate all the information, which he collected to his king. Therefore, he viewed himself as the agent of Choson monarch in Japan, who is captured but still he did his best to study Japan and understand this country and its people. Therefore, the main driver, which determined the decision of Hang Kang to create his book, was the attempt of the author to create the book that would uncover the truth about Japan to Korean people and the monarch.In such a context, he viewed himself as a servant of his king and presented himself in the book as a devoted servant, who did his best to help the king of Korea to understand better Japanese culture and society. In such a way, he expect ed to inform the king about the essence of his major enemy. Therefore, he presents himself primarily as the servant of his king. He remains a servant of his king, even when he is a captive. In such a way, he does not recognize the authority of Japanese since he does not view Japanese Emperor as his new ruler, although formally he was a captive of Japanese than Japanese decided his future and his life was in their hands. In such a way, he turns out to be a true patriot of his country and devoted servant of his monarch. He resisted to any influences from the part of Japanese. On the contrary he stood firmly on his ground and neglected all efforts of Japanese to assimilate him and made him a part of their community.In this respect, he was fully aware of the risk of becoming absolutely inferior to Japanese because, as a captive, he would take the lowest level in the social hierarchy of Japanese society. However, he rejected Japanese culture and stuck to his own culture, norms and tradit ions, which made him different from other captives and from Japanese. As a result, he represents himself as a person, who has preserved spiritual and cultural independence, even when he was a captive. In such a way, he became the independent captive such oxymoron is the best characteristic of Hang Kang in Japan and his book reveals that he was really free in his mind and spirit but physically he remained a captive. Therefore, he always remained Korean in Japanese society. He was an outsider, a stranger in Japanese society, which he viewed and studied from the perspective of a captured Korean.However, he was not the average Korean captive of Japanese. Instead, he was able to view Japanese from neo-Confucian rather than narrowly Korean perspective. Neo-Confucian views helped Kang Hang to develop a broader view on Japan and his position in Japan. He promoted his neo-Confucian ideas among Japanese. In this regard, he did not even need to develop a close communication with them or persua de them through disputes and extensive arguments. Instead, he just stood on his ground and his difference became obvious for Japanese and they grew interested in his views and beliefs that would help them to develop a new, neo-Confucian perspective on their life. Neo-Confucian ideas were absolutely new for Japanese society and they attracted many Japanese, who knew Hang Kang in person. He became a source of new ideas, a new worldview which was unusual for Japanese. Hence, Hang Kang became not a mere captive but, instead, he became a person, who expanded his values, beliefs and worldview rather than assimilated into Japanese society and culture. Japanese apparently did not expect such impact of the captive on their views and beliefs.Even though Kang Hang remained a servant to his king and people, he has managed to analyze Japanese culture and society critically. The experience of the deeper contact with Japanese culture and society helped Hang Kang to develop a broader world on himse lf, his cultural background, Japanese and wider world. in this regard, it is worth mentioning the fact that the development of his views was still vulnerable to the impact of Japanese culture. In fact, Hang Kang has managed to overcome the direct impact of Japanese culture but the study of Japanese culture and his new social environment expanded his worldview consistently. In the course of the book the evolution of the narrator becomes obvious (Kim 101). At the beginning of the book he was Korean, a servant fully devoted to his king and his people. However, in the course of the book, he becomes a neo-Confucian, who has learned to appreciate other cultures and develops a sort of tolerance which help him to view other cultures as different. On the other hand, he has never managed to get rid of his cultural supremacy compared to Japanese, whom he believed to be unable to civilization because their primary concerns were invasion and grandiosity of their empire, whereas he, being a neo-C onfucian, was more concerned with himself, his family, his community, country and his king. He believed Japanese to be unable to civilization. This helped Hang Kang to remain indifferent to Japanese culture and resistant to its impact. Instead, he remained devoted to his neo-Confucian principles.In such a way, Hang Kang preserved his devotion to Choson society but he has developed a broader view on his position in society and his environment. In fact, he has managed to overcome biases associated with the traditional view of Koreans on Japanese. Hang Kang has managed to view Japan from within, although he remained an outsider but he believed that the study of Japanese culture and society was essential for his country. He believed his society was still more advanced and civilized compared to Japanese one but his devotion to his society was accompanied by the impact of neo-Confucian ideas, which helped him to view Japanese culture as a new phenomenon that he studied in details trying t o understand and describe in his book. The detailed description of his vision of Japanese society was essential for Choson society, which was unaware of its enemy, because Japan focused on the invasion of Korea and Koreans had to know the enemy to be able to confront him effectively. In this regard, Hang Kang performed a dubious role. At any rate, he represents himself as an outsider in Japan because he is virtually a spy of Choson king. On the other hand, he is the insider in Japan for Choson society because he lives there as a captive. As a result, Koreans perceive him as insider in Japan, whereas he is an outsider for Japanese because he sticks to his neo-Confucian philosophy and Choson background and cultural norms and traditions.Hang Kang also became the promoter of neo-Confucian ideas. He always stuck to his neo-Confucian views, in spite of the fact of being captive and under the permanent impact of Japanese cultural environment (Yasunori 2). Moreover, he always attempted to c onvey his ideas to Japanese and spread neo-Confucian philosophy in Japan. In this regard, Confucian ideas have never been presented in Japanese society. Japanese were not acquainted with Confucian ideas and did not take them seriously because of the physical distance and cultural barriers between Japan and China and Korea, where Confucian philosophy was historically widely-spread and popular. In fact, it was Kang Hang, who was one of the first neo-Confucians, who brought in this new philosophy to Japan. Therefore, Hang Kang viewed himself not only as a Korean spying over Japanese and studying Japanese society, political structure and culture, but also as a neo-Confucian. In this regard, he viewed spreading neo-Confucian ideas among Japanese.Thus, Hang Kang depicts himself from multiple perspectives in his book. At first he appears as a patriot of his country and devoted servant. He remains a devoted servant of his king and patriot of his country throughout the book but his personali ty evolves and uncovers new aspects of his life and views. Steadily, his neo-Confucian ideals become obvious as he confronts Japanese culture, which turns out to be absolutely different from his own views, beliefs and cultural norms. He studies Japanese culture and society to tell about them to his king and country. He performs the role of a spy for his king in Japan. At the same time, he is not a mere captive for Japanese. Instead, he is rather a neo-Confucian philosopher, who brings in new ideas that Japanese learn from him.
