Literature in the Dark Ages: the Apocrypha

Educator Rodgers Humanities I November 5, 2010 Literature in the Dark Ages: The Apocrypha The Dark ages is alluded to as such for some reasons there was plague and affliction that hit mankind during this time and individuals lived in dread to give some examples. In any case, one principle reason is the way that very little data exists about this period ever. Almost all the old basic writings were lost during the Middle Ages. Head Flavius Juvianus requested the consuming of Antioch Library.Tons of books were scorched. Agnostic sanctuaries and libraries were plundered or burned to the ground (1). During the Dark Ages the writing by church was delivered and protected more than some other writing. The congregation was viewed as the expert on insight at that point so it was there works that were recreated in the best volume. Pastorate accordingly ruled writing during this timespan. It was in the Dark Ages that there were records of upwards of 200 epistles and records of the life of Jesus Christ that were said to have been written.Only 27 were safeguarded. Of the 193 that were disposed of Claytor 2 a few people believed them to be fiction bits of writing, some regarded them as evident and to some they were believed to be false. The compositions that were accepted to have been abused by Christians during the Dark ages are regarded by some as lost profound lessons. Truth be told a portion of these lessons were found in 1945 and they elucidated the lessons that are recorded in the bible.They discuss a mystery good news of Mark, mystery lessons of John, a record of the Gospels composed by Thomas, the Apocalypse of Paul, just as otherworldly understanding composed by a lady which is called Pistils Sophia. These lessons are by a gathering called Gnostics. Gnostics were Christians whose conviction framework depended more upon information than confidence. Their name is inferred the word Gnosis which is otherworldly knowledge. They vigorously grasped the covered up writings.I t is likely that because of their Criticisms and contrasts with the Roman Orthodox church that individuals from the Gnostic group were scorched at the stake and a large number of their compositions crushed by the Church. Prior to the disclosure of Gnostic compositions, our lone information on extra records of the life and demise of Jesus Christ originated from a letter composed by Church Father Clement of Alexandria (150 AD †211 AD). In the letter Father Alexandria cites this mystery gospel and alludes to it as â€Å"a increasingly profound gospel for the utilization of the individuals who were being idealized.  He stated, â€Å"It Claytor 3 even yet is most painstakingly monitored [by the congregation at Alexandria], being perused uniquely to the individuals who are being started into the incredible secrets. (2). It is essential to take note of that while Father Alexandria was a defender of Gnosis, which was an information or understanding into the interminable, he dismis sed the idea as characterized by the Gnostic group. The abused works were considered by certain researchers as According to the Early Christian Church the extra compositions of the life of Jesus were viewed as valuable yet were discarded from records since they weren’t viewed as supernaturally inspired.The accounts were isolated into two classifications. They are considered either sanctioned or non-standard. The authoritative works are those that were remembered for the accounts in the book of scriptures. The non-accepted were called were viewed as spurious. The word Apocrypha actually implies concealed compositions. While the various parts of the early church differ about which works were sanctioned and which were fanciful they all bought in to the conviction that a few compositions were supernaturally roused by God and others were most certainly not. Inside the fanciful works are records of the earliest stages of Jesus in which they account the adolescence of Jesus.There ar e those that give alternate points of view of the interests and the Gospel of Thomas records numerous idioms of Jesus that are Claytor 4 excluded from the holy book. The early Christian church esteemed a significant number of these works valuable yet don't accept all were supernaturally propelled. There are the individuals who accept the lost compositions are fake or fiction works. Some of them that buy in to this conviction have inferred that, regardless of whether sanctioned or spurious, none of the records of the lives of Jesus are true.They accept that by discarding 173 of 200 records of the life of Jesus the congregation demonstrates that it utilized the compositions they chose to simply keep up their capacity and control. Edward Gibbon, a history specialist whose work has been vigorously scrutinized by the Christian church, composed â€Å"The source of these fake reports was as a matter of fact the congregation. Gibbon lets us know: â€Å"Orthodox scholars were enticed, by t he confirmation of exemption, to make fictions, which must be trashed with the designations of misrepresentation and fabrication. They attributed their own polemical attempts to the most admired names of Christian artifact. Other people who challenge the legitimacy of these compositions are Christians who trust a few records to be valid however not others. J. G. Davis, A Christian educator of Theology, wrote in his book The Early Christian Church â€Å"(they are only) another classification of writing, formulated for perusing by the reliable during their recreation time, and comparing somehow or another to the books of a later period. † Claytor 5 The persecuted old works of Christianity are very controversial.There are next to zero realities about the compositions that are not discussed, differ upon or discredited somehow or another. What is clear is that there are a few compositions about the life of Jesus that are either right now in presence or obviously existed sooner or later ever, in spite of the fact that the quantity of spurious works is unsure. It is additionally sure that these compositions give a record of indistinguishable events from those thought about accepted by the early Christian church. They are firmly related compositions that are recorded in the holy book and considered by Christians as the genuine records of the life of Jesus.Claytor 6 Cited Workshttp://hesitant ambassador. com/Lost-Doctrines-Christianity003. htm  The Early Christian Church, p. 83 (1965).

Is Sex Addiction Real, a Joke, or Just an Excuse

Is Sex Addiction Real, a Joke, or Just an Excuse Addiction Addictive Behaviors Sex Print Is Sex Addiction Real, a Joke, or Just an Excuse?

Learn about our editorial policy Elizabeth Hartney, BSc., MSc., MA, PhD Medically reviewed by Medically reviewed by Steven Gans, MD on August 05, 2016 Steven Gans, MD is board-certified in psychiatry and is an active supervisor, teacher, and mentor at Massachusetts General Hospital. Learn about our Medical Review Board Steven Gans, MD Updated on May 25, 2019 More in Addiction Addictive Behaviors Sex Caffeine Internet Shopping Alcohol Use Drug Use Nicotine Use Coping and Recovery Sex addiction is a phenomenon we are hearing more and more about these days. Of all the addictions, sex addiction is most commonly the butt of jokes such as, If I was going to have an addiction, Id go for sex addiction. This raises the question, is sex addiction real? Many people dismiss sex addiction as a futile attempt to give legitimacy to what is simply irresponsible or greedy behavior. Others say that those people are unaware of or indifferent to the emotional pain that is frequently reported by those who consider themselves sex addicts and their loved ones. Arguments For Sex addiction triggers the brains reward system similar to other addictions Sex addicts often have other addictions as well Sex addictions can result in significant distress and impairments in functioning Arguments Against The sex addict label may be a moral judgment It may be used as an excuse for irresponsible sexual behavior Some believe addiction is chemical and not behavioral Background Sex addiction is not a new concept. Historical records dating back to ancient Rome and second century Greece report excessive sexuality, also known as hypersexuality or hyperaesthesia, and nymphomania or furor uterinum (uterine fury) in women. The modern concept of sex addiction was popularized by Dr. Patrick Carnes, author of Out of the Shadows: Understanding Sexual Addiction, and clinical director of sexual disorders services at a clinic in Arizona. Carnes and his colleagues have written several books on the subject, and tend to dominate popular understanding of sex addiction. However, others have also written extensively on the subject, including both researchers and people who believe they have suffered from sex addiction. Goodman argued that, although sex addiction shares features of both a compulsive and an impulse control disorder, it does not fit clearly into either category. He suggested that it is best described as an addiction and proposed diagnostic criteria that mirror the criteria for alcohol and substance dependence in the DSM 5, the reference manual for clinical diagnosis. Sex addiction was not included in the DSM 5, despite a number of conditions relating to limited sexuality â€" such as hypoactive sexual desire disorder and sexual aversion disorder â€" being included. This belies a bias that challenges the recognition of excessive sexual desire or expression as a problem. In other words, regularly experiencing sexual desire, physical sexual arousal, sexual relations, and achieving orgasm is considered the norm for both sexes, despite the fact that people who never experience difficulties at any of these stages of the sexual experience are in the minority. In general, having less sexual desire and activity is seen as a greater problem than having more sexual desire and activity. Over the past century, society has become increasingly permissive, with various aspects of sex and sexuality forming the basis for many types of entertainment. In recent decades, the pharmaceutical industry has supported this, with the development of drugs such as Viagra reinforcing the view that one is not living a complete and happy life without regular, non-problematic sex. In this climate, it is not surprising that so many people are becoming preoccupied with sex, and that those who might in the past have succumbed to other pleasures are developing compulsive sexual behaviors. How to Tell If You Are a Sex Addict Sex Addiction in the Headlines Sex addiction gained widespread attention in 2009 when actor David Duchovny â€" apparently happily married with a family â€" surprised the world by publicly admitting to being a sex addict and going into rehab. Toward the end of the year, many speculated whether or not golfer Tiger Woods was a sex addict after several women claimed to have had extra-marital affairs with him. The Role of the Internet The Internet has led to an unprecedented amount of porn being made available to anyone with a computer. Many people are bombarded with advertising for porn and commercial sex sites without even seeking them out. Many more people are being exposed to porn than ever before, including children and adolescents, and the nature of the web makes it difficult (if not impossible) to censor or place limits on the nature or amount of what is portrayed. In addition, it is easy to find and conduct an online affair, or online dating through sites such as tinder. At the same time, there is increasing concern about online porn addiction, a type of online sex addiction, which far outstrips the provision of support for people who feel their porn use is excessive, unmanageable, or causing them problems. Without sufficient specialized treatment services, relationships and families will continue to struggle, often in secret, with problems that they are not adequately equipped to deal with. The semi-underground and often corrupt nature of the sex industry has rendered it useless in providing research or treatment funding or other supports for people who are harmed by its output. This differs from the gambling industry, for example, which has funded research into treatment and services. Case for Sex Addiction Research indicates that the same reward system in the brain is activated in sex addiction as in a number of other addictions, including drug addictions. This supports the idea that sex addiction has a similar physiological and psychological process as other addictions. People with sex addiction often have concurrent substance and/or behavioral addiction problems, or crossover to other addictions when they attempt to overcome their sex addiction. Some authors argue that the existence of crossover addictions lends support to the legitimacy of sex addiction as a real addiction and that, if recognized, cross-over risk can be addressed directly to prevent it from happening after treatment for other addictions. Sex addiction causes a great deal of distress to those affected and their loved ones. Sexual desire and expression in people with sex addictions are commonly reported to be unmanageable and unpleasant, in stark contrast with the way that healthy sexual experiences are reported, which are typically described as fulfilling and satisfying both physically and emotionally. Recognizing sex addiction means these people can get the help they need to overcome their addiction, and eventually resume enjoyable sexual relationships. At present, few readily accessible addiction services provide help for people with sex addiction. Recognition of sex addiction can allow sex addiction treatment to be included in community addiction services. With specialized training in sex addiction being provided to addiction services staff, many more people could easily access help for sex addictions. Case Against Sex Addiction An important criticism of the sex addiction concept is that it does not provide enough differentiation between different conditions that might look like sex addiction, such as hypersexuality accompanied by mania or hypomania in bipolar disorder; character disorders; personality disorders; some forms of depression; OCD and PTSD. Critics of the concept of sex addiction argue that it has grown out of a cultural focus which associates sex with danger, powerlessness, and victimization, and is just a new way of making moral judgments about people who enjoy sex. As such, it can be used by people with a political and/or religious agenda to be negative about sex. There is also a risk that the label of sex addiction might pathologize normal sexual desire and behavior, making healthy people appear to have an illness that does not exist. The concept of sex addiction has also been criticized for being based on the idea that some sexual experiences, for example, intimate relationship sex, are better than others. These are argued to be moral rather than clinical arguments. At the other end of the spectrum, some people believe that a label like sex addiction can be used as an excuse for irresponsible sexual behavior, such as rape and child molestation. According to this criticism, people who have committed sex crimes can hide behind the label of sex addiction and avoid taking responsibility for their actions. These acts are deemed to be inexcusable, and the idea that a sex addiction diagnosis encourages pity and sympathy to people who do not deserve sympathy is also inexcusable. Finally, there is the argument leveled at all behavioral addictions â€" that addiction is about chemical dependency, and no matter how similar the patterns of behavior, addictions occur in relation to addictive substances and not behaviors. Where It Stands Sex addiction, or certainly excessive sexual behavior, is widely recognized in the media and in popular culture. The growth of the internet has lead to an unquantified escalation of cybersex addiction, which includes both addictions to pornography and addiction to online sexual interactions with partners, including sex workers. The psychiatric community has been hesitant to acknowledge excessive sexuality, in and of itself, as a disorder. In 1987, the Society for the Advancement of Sexual Health (SASH) was founded to provide up-to-date research to professional members who work with sex addictions, and to the public. They publish the journal  Sexual Addiction and Compulsivity: The Journal of Treatment and Prevention,  and hold a conference annually to disseminate research findings on sex addiction.

Microeconomics Income Inequality For Fast Foodservice...

Microeconomics: Income Inequality for Fast Foodservice Industry Income inequality is a very important concept to talk about when we really go deep into microeconomics. In the United States alone there are sectors that have income inequality that has been in our headline news for the past years, and to top off the list would be fast foodservice. There has been a lot of studies that looked into CEO-to-worker compensation ratios across all labor forces that show fast foodservice industry is the most unequal sector in American economy (Jaimeson, 2014). This inequality of wages can easily be explained and will be fully detailed in this paper. That is why it is important to look into cause of income inequity from a foodservice industry†¦show more content†¦We can see this inequality from CEO position having their pay doubled in 2009 for the decade of the year 1990s, which was quadrupled average pay than for the year 1980s.That was also eight times the CEO average for all the decad es if the mid-20th century. With this we can see over the years to decades we can see CEO pay has increased a lot more than expected to be, and still growing. Looking at hourly wages of non-corporate pay that has been the same since the early 1970s. Studies have shown between 1947 and 1972 it was said to have hourly wages only rose 76%, but ever since it has only risen 9% (Income Inequality, n.d.). While CEO pay has been growing exponentially, we can see other hourly pay hasn’t been increasing since the 1970’s which is hard to believe. CEO Pay Compares to Typical Workers According to a report created by Ruetschlin (2014) stating that compensation practices that is seen within companies of fast food industries is â€Å"out of line† with rest of our economy. We can see that CEOs have the greater and greater economic rewards while workers don’t seem to reap those rewards so luckily. In Ruestschlin studies, she was able to piece together that CEO average pay since 2000 has quadrupled in numbers than the typical workers. That in 2013, the average CEO took home a whopping $23.8 million dollars unlike typical works that doesn’t even have that much if we were to combine each worker in every food establishment. We can

Based on the report of Global Youth Justice Organization, the misuse of marijuana is the common juvenile crime performed by the youth. Marijuana abuse was ranked to be #6 in their list.

How Technology Has Changed Our Lives in Just 10 Years Free Essays

Q: How has technology changed in the past 10 years? A: The biggest technology change of the last 10 years is the proliferation of the internet into mainstream society.

We will write a custom essay sample on How Technology Has Changed Our Lives in Just 10 Years or any similar topic only for you Order Now Q: Why has it changed? A: The internet is a better mousetrap.

The internet is fast, affordable, and widely available. What’s more, it seems to facilitate some innate human desires to share, to be liked, and to be in control of our environment. The internet age is customizable, on-demand, instantaneous. Q: Is it all good? Why or why not? A: Everything is a tradeoff. The internet accelerates many aspects of life, and sometimes that can be a scary thing. However, the good outweighs the bad. Over time the global nature of the internet will help normalize the standard of living around the world. This might be unattractive to prosperous nations in the short term, but in the long term it is good for everyone. Q: What will technology be like 10 years from now? A: Ten years from now we’ll be interacting with devices (and by extension, each other) using sophisticated I/O hardware that tracks our eye movements, senses the motion of our bodies, and possibly even reads our thoughts. It sounds like science fiction, but there are companies who are already competing in these areas. In terms of output, I would not be the least bit surprised to see advances in sense areas that are currently ignored – i. e. taste, touch and smell.

Amazon Value Proposition Essays

Amazon Value Proposition Essays Amazon Value Proposition Essay Amazon Value Proposition Essay Its value proposition was mainly the ease of election and convenience to the book lovers and they translated the same value in the other segments after diversifying. Its revenue model is Sales revenue model as it derives its revenue from selling of goods, information and services. It also derives a majority of its sales from third party sellers who sell product on Amazon. Process followed and issues faced while selecting the company: Before starting with which company to pick for, tried to understand about the history of the e-commerce as discussed in detail in class. Then, searched to find some of the best known e-commerce companies. There were issues like there is too much information on the internet and there is not one particular company which one can find complete to understand at this junction of the course. Have taken this particular company because of its repeated reference in all the books and lectures. Also, another reason for picking up this company is that Amazon does not only act in the ICC domain but also EBB. Along with that it was a first mover in its market place so it will be interesting to know how they managed it. My objective will be to understand its current value proposition and revenue model. Talking about revenue model, noticed one thing that although it is primarily sales revenue model but it also allows companies to advertise their products by paying to be listed as featured products. So, is it purely a sales model or has an essence of advertising model also? This question will try to understand in detail. One other objective which I would like to cover in this course is that in year 201 3, it entered Indian e-commerce market as Amazon. In. The difference in he Indian scenario is that due to regulatory hurdles, it can not own any of the merchandise it sells. So, it primarily acts as a sales channel. Therefore, it will be interesting to study how they will tweak their business model to stay competitive against local and established players like Flippant, Snappers etc.

The Uses and Advantages of Corrugated Plastic

The Uses and Advantages of Corrugated Plastic There are two main types of corrugated plastic. Corrugated plastic sheet usually comprises what appear to be three layers - two flat sheets with a ribbed center layer. In fact, they are really two layers, often referred to as twinwall plastic. Corrugated plastic can also mean sheets of plastic which are wave-like in profile and may be reinforced with chopped glass fiber. They are a single layer and used mainly for roofing of garages and outhouses, but gardeners also use them to build sheds. Here we will focus on the twinwall version, also known as a corrugated plastic board or fluted plastic board. How Corrugated Plastic Sheets Are Made The materials used include polypropylene and polyethylene, widely used and versatile thermoplastics. Polypropylene has a neutral ph and is resistant to many chemicals at normal temperatures, but can be dosed with additives to provide a variety of other resistance such as UV, anti-static and fire resistance, for example. Polycarbonate is also used, but this is a much less versatile material, particularly in respect of its relatively poor impact resistance and brittleness, although it is stiffer. PVC and PET are also used. In the basic manufacturing process, the sheet is extruded - that is the molten plastic is pumped (typically with a screw mechanism) through a die which provides the profile. Dies are typical 1 - 3 meters wide, delivering a product of thickness up to 25 mm. Mono- and co-extrusion techniques are used depending on the precise profile required. Advantages and Uses In buildings: Suppliers claim it is an ideal material for storm shutters and that it is 200 times stronger than glass, 5 times lighter than plywood. It does not require painting and maintains its color, it is translucent and does not rot. Clear polycarbonate corrugated sheet is used for roofing sunrooms where its rigidity, lightweight and insulating properties are ideal, and low impact resistance is less of an issue. It is also used for small structures such as greenhouses where its air core provides a useful insulating layer. Humanitarian Relief: The material is ideal for temporary shelters need after flood, earthquake and other disasters. The lightweight sheets are easily transported by air. Easy to handle and fix to wooden frames their waterproof and insulating properties offer rapid shelter solutions when compared to traditional materials such as tarpaulins and corrugated steel sheets. Packaging: Versatile, flexible and impact resistant, polypropylene board is ideal for packaging components (and agricultural produce too). It is more eco-friendly than some molded packaging which cannot be recycled. It can be stapled, stitched and easily cut to shape with a hobby knife. Signage: It is available in a wide variety of colors, is readily printed on (typically using UV printing) and can easily be fixed using a wide variety of methods - its light weight being an important factor. Pet enclosures: It is such a versatile material that rabbit hutches and other domestic pet enclosures are built with it. Fittings such as hinges can be bolted to it; being non-absorbent and easy to clean it offers a very low maintenance finish. Hobby Applications: Modellers are using it to build airplanes, where its light weight combined with rigidity in one dimension and flexibility at right angles provides properties ideal for wing and fuselage construction. Medical: In an emergency, a section of a sheet can be rolled around a broken limb and taped into place as a splint, also providing impact protection and body heat retention. Corrugated Plastic: the Future The uses that this category of board are put to demonstrate its fantastic versatility. New uses are being identified almost every day.  For example, a patent has recently been filed to use layered sheets (alternate layers fused at right angles) in air-to-air heat exchangers. Demand for corrugated plastic is sure to grow, but as many of the plastics used are dependent on crude oil, the raw material costs are subject to the fluctuations (and inevitable growth) of oil prices. This may prove to be a controlling factor.

American Civil War Assignment Example | Topics and Well Written Essays - 1500 words

American Civil War - Assignment Example The southerners wanted to crop their land into the newly acquired states so that they could extend their cotton fields. Acquiring new land meant that these people would require more slaves thus making Texas and other states slave states. Northern states wanted the new states from Mexico to be free states. This motion was moved in congress but was always opposed by the southern states because they had a higher representation in the senate. David Wilmot, the congressman of Pennyslavania, introduced the Wilmot Proviso of 1846, which advocated for mexican acquired states from to be free from slavery. The Wilmot Proviso was raised in the house of representatives. Its main aim was to raise funds to support peace negotiations to end the Mexican American War. The Wilmot Proviso was also supporting a bill by President James Polk to raise 2 million dollars to end the war. The intention of the Wilmont Proviso was to prevent slavery being introduced in the new Mexican states. The Wilmont Proviso was passed to the senate for approval, but was never approved. Some parts concerning the Proviso were passed. The Free Soil Party was also against the introduction of slavery in Texas and other states acquired from Mexico. This party was strong in the New York city and was mainly supported by the former anti-slave members of the Democratic Party. The Free Soil Party, which lasted between 1848 and 1852, argued that free soil and free people contributed better to the growth of the economy. California sought to be recognized as a free state in 1849. This was faced by opposition especially from the southern states that advocated by slaves providing cheap labour for their farms and working long hours. The request was also controversial because gold had been discovered in California and there was a Gold Rush. Henry Clay drafted the Compromise of 1850 that admitted California as one of the free states, and other territories such as Nevada, Utah, Arizona and New Mexico would not have slave ry any more. Another development in the Compromise of 1850 was the solution to the Texas border problem. Additionally, in Columbia, the slave trade that was practised in the area was abolished, but slavery was still permitted. The Compromise of 1850 increased the number of free states, causing an imbalance between the states supporting slavery and free states. This contributed to the American Civil War. 2 The Kansas-Nebraska Act of 1854 was created by the Senator of Illinois Stephen Douglas. This act, which involved two territories Kansas and Nebraska, allowed these territories to decide for themselves if they wanted to allow slavery in their land. This arrangement was against the Missouri Compromise of 1820 which did not allow slavery north of latitude 36 degrees 30’. Following the enactment of the Kansas-Nebraska Act, those supporting slavery and those against moved into the Kansas and Nebraska teritorries in order to affect the outcome of the elections. The first election since the passing of the Kansas-Nebraska Act was held. Those supporting pro-slavery won, but the election was nullified because of rigging. Other elections were held by the supporters of anti-slavery, but the rest refused to vote. This led to a war between the anti-slavery supporters and those supporting slavery. After the war, both parties established parallel governments within the territory and Kansas was not recognized as a state. In another election, the pro-slavery supporters won but again accused of cheating in the elections,

Culture Walk Assignment Example | Topics and Well Written Essays - 500 words

Culture Walk - Assignment Example Faustian the term implies a situation where the person is very ambitious in his life and wants to achieve success in life. However, improvements in technology has made people to be in a rat race as they are always in a hurry to gain more power and position and achieve success in life as early as possible. Therefore, to meet with the growing competition and culture people sometime give up their moral integrity just to win the race of life. With concern to the cultural walk regarding the different phases of life it is observed that since the beginning of life individuals always wants to know the purpose of their existence. The realities of life that is birth, death are not known to anybody and therefore people search for the reason behind their life. People often find themselves in a situation where they may think that what will happen and where will they go after life ends. This made the people thing that whether they will return to earth if they die. As we are moving with the improve ment in technology, people from all the walks of life following different cultures are more willing to know about their future existence on this planet. People are always with the problem of identifying their purpose of life. The universe, the life on earth and mankind all are the gift of god and nature and so are to be judged equally as believed by individual. Moreover, people from different cultural background have varied views towards life and the perception of individuals has also changed due to technology. People are no more close to the nature hence affecting their walk of life. With regard to this aspect of life it can be depicted that life has become more materialistic and happiness are no more grounded with nature. Kirkpatrick Sale mainly focuses on the technology and the various challenges people are facing due to the improvements in the technology. The Rebel against future takes us back to the period of 1811 when people were feared of Luddite rebellion. The

The Frequency Spectrum Allocated By Malaysian Communication Computer Science Essay International Mobile Telecommunications-2000 (IMT-2000), also known as 3G or 3rd Generation, is the generation standard for mobile phones and telecommunication services. This generation is to meet specifications by the International Telecommunication Union. Various applications exist, including wide-area wireless voice phone, video calls, mobile, mobile TV Internet access and others. The details spectrum for IMT-2000 shows like below: International Mobile Telecommunications-2000 (IMT2000) Frequency Division Duplex (FDD) Upper band: 2110 to 2200 MHz Lower band: 1920 to 2010 MHz Time Division Duplex (TDD) Frequency: 1915 to 1920MHz Frequency: 2010 to 2025MHz Figure 1.1: Frequency spectrum IMT-2000.[2] Global system for mobile communications (GSM) is a second generation cellular telecommunications system was first designed in the 1980 [12]. Compared with the first generation, GSM is more advanced enhancements such as in security, quality, capacity, and the ability to support integrated services. For examples GSM services is GSM-900 and GSM-1800 in which used in the world like Europe, the Middle East, parts of Asia and others country. The details spectrum for GSM900 and GSM1800 shows like below; Global System for Mobile (GSM) in the 900 MHz Band Upper band: 925 to 960 MHz Lower band: 880 to 915 MHz Global System for Mobile System in the 1800 MHz Band Upper band: 1805 to 1880 MHz Lower band: 1710 to 1785 MHz Figure 1.2: Frequency spectrum GSM900.[2] Figure 1.3: Frequency spectrum GSM1800.[2] Summary for Service Operators [ Maxis, Celcom, Digi and U-Mobile]; Service Operator System Standard Frequency Spectrum (MHz) Access Code Commercial Name Service Offered Lower Band Upper Band Maxis Mobile Sdn Bhd GSM 900 GSM 1800 IMT-2000: FDD TDD 880-886, 905-915 1710-1735 1935-1950 2015-2020 925-93, 950-960 1805-1830 2125-2140 012 017 Maxis Voice call, SMS, MMS, data plans service, International roaming, WAP Celcom (Malaysia) Berhad GSM 900 GSM 1800 IMT-2000: FDD TDD 888-905 1735-1760 1950-1965 2020-2025 933-950 1830-1855 2140-2155 013 019 Celcom Voice call, SMS, MMS, data plans service, International roaming, WAP Digi Telecommunication Sdn Bhd GSM 900 GSM 1800 IMT-2000: FDD TDD 886-888 1760-1785 1965-1980 2010-2015 931-933 1855-1880 2155-2170 010 016 Digi Voice call, SMS, MMS, data plans service, International roaming, WAP U-Mobile Sdn Bhd IMT-2000: FDD TDD 1920-1935 1915-1920 2110-2125 018 U-mobile Voice call, SMS, MMS, WAP Question 2 The Fourth Generation (4G) technology candidates is foreseen most likely to be between Long Term Evolution Advanced (LTE-Advanced) proposed by the Third Generation Partnership Project (3GPP) and Mobile WiMAX using 802.16m standardised by the Institute of Electrical and Electronics Engineers (IEEE). Distinguish the technical differences between these two technologies and give your opinion on the scenario and deployment of 4G in the near future. Long Term Evolution Advanced (LTE-Advanced) proposed by the Third Generation Partnership Project (3GPP) 3GPP Long Term Evolution (LTE) is new standard in networking technology tree move what was once realize GSM/EDGE and UMTS/HSxPA networking technologies. It is a project Generation Partnership Project third (3GPP), administered under one name trademark by one of associations in partnership, European Telecommunications Standards Institute. LTE Evolution Figure 2.1: Mobile Technologies Charging The first generation of cellular systems were based on analog standards and are introduced in 80s middle. This with quick to bring to one second generation digitals cellular standard that made use of digital modulation and signal processing. The second generation also led to a technology fragmentation. Once many standard contests exist, however what remains now are two main branches: referred to as GSM and CDMA branches or alternately referred as the 3GPP and 3GPP2 branches. These branches remained separate as they migrated to 3G systems focusing on more efficient voice transport as well providing data-services. LTE originated in the 3GPP standards organization, and a competing specification (EV-DO Rev C) started in the 3GPP2 body as the next evolutionary step. However, the support for EV-DO Rev C has waned and it has now become clear that the 3GPP2 radio interface evolution has effectively ceased, allowing a single cellular technology. Figure 2.2: LTE provides a smooth evolutionary path for operators deploying all 3GPP and non-3GPP technologies. Technology Summary of LTE FDMA on uplink Scale able OFDM on downlink, Single Carrier Variable Spectrum Width from 3 to 20 MHz Up to 64 QAM, MIMO, Spatial Multiplexing(SM), LTE- Advanced Will be an evolution of LTE. Therefore LTE-Advanced must be backward compatible with LTE Release 8. Requirements will meet or even exceed IMT-Advanced requirements following the ITU-R agenda. Should support significantly increased instantaneous peak data rates in order to reach ITU requirements. Primary focus should be on low mobility users. It is required a further improvement of cell edge data rates. Mobile WiMAX using 802.16m standardised by the Institute of Electrical and Electronics Engineers (IEEE) IEEE 802.16 is a series of Wireless Broadband standards authored by the IEEE. The current version is IEEE 802.16-2009 amended by IEEE 802.16j-2009. IEEE 802.16 is written by a working group established by IEEE Standards Board in 1999 to develop standards for the global deployment of broadband Wireless Metropolitan Area Networks. The Workgroup is a unit of the IEEE 802 LAN/MAN Standards Committee [3]. WiMAX Evolution WiMAX grow almost independently (and in parallel) for cellular standard mentioned earlier. In late 90s, IEEE started a workgroup create one air interface to show multipoint wireless standard broadband. Working group lever DOCSIS (data on interface specification cable service) standard heavily especially in definition MACs layers. Original standard modified into 802.16d in 2004 introduce OFDM as transmission scheme. This standard intended at fixed applications and is sometimes referred to as fixed WiMAX. In 2005, 802.16d further improving to for support for mobility and provide OFDM delivery system scalable. This standard known as 802.16e/ mobile WiMAX. (It should be noted that products based on 802.16d and 802.16e inhering market and both classified as WiMAXs products lead to a few ambiguity on specific standard which is supported-802.16d or 802.16e.) Hope, 802.16e standard expanding to 802.16m which focusing on addition to ventilate interface specifications. This evolution is shown in Figure 2.3. Figure 2.3: WiMAX Evolution Technology Summary of WiMAX Scale able OFDM on downlink and uplink Variable Spectrum Width from 1.25 to 10 MHz Up to 64 QAM, MIMO, Spatial Multiplexing, Beamforming Mobile WiMAX deployed since 2008 IEEE802.16m and Mobile WiMAX Release 2 Lower latency through faster MAC/signaling Higher spectrum efficiency through more advanced and higher order MIMO solutions, including multiuser MIMO as well as lower MAC and PHY overhead. Higher peak and user data rates using wide-band carriers (including 20 MHz) and multicarrier aggregation. Enhanced coverage in high interference environments with improved preamble and control channel. Support for higher mobility through a faster feedback mechanism and link adaption. Flexible spectrum deployments (both FDD and TDD support contiguous bands) The scenario and deployment of 4G in the near future 4G refers to the fourth generation of cellular wireless standards. It is a successor to 3G and 2G families of standards. The first was the move from 1981 analog (1G) to digital (2G) transmission in 1992. This was followed, in 2002, by 3G multi-media support, spread spectrum transmission and at least 200  kbit/s, soon expected to be followed by 4G, which refers to all-IP packet-switched networks, mobile ultra-broadband (gigabit speed) access and multi-carrier transmission. Pre-4G technologies such as mobile WiMAX and first-release 3G Long term evolution (LTE) have been available on the market since 2006 and 2009 respectively. According to the members of the 4G working group, the infrastructure and the terminals of 4G will have almost all the standards from 2G to 4G implemented. Although legacy systems are in place to adopt existing users, the infrastructure for 4G will be only packet-based (all-IP). Some proposals suggest having an open Internet platform. Technologies considered to be early 4G include: Flash-OFDM, the 802.16e mobile version of WiMax (also known as WiBro in South Korea), and HC-SDMA (see iBurst). Question 8 The public cellular service operator in Malaysia are subjected to mandatory standards for Quality of Service (QoS) or Grade of Service (GOS) by Malaysian Communication and Multimedia Commission (MCMC). List various parameters and schemes used for providing QoS/GOS in cellular network and discuss their advantages/disadvantages to the subscribers and operators. How can QoS provisioning be managed in the future 4G cellular network? There is two ways to measure the quality of voice services, Grade of Service (GoS) and the Quality of Service (QoS). GOS can be describe as a chances of a call in a circuit group being blocked or delayed for more than a specified interval and can be expressed as a vulgar fraction/decimal fraction. This is likely to happen to the busy hour when the traffic intensity is the greatest. Grade of service can viewed from the perspective of incoming versus outgoing calls, and is not necessarily equal in each direction or between different source-destination pairs. Quality of service (QOS) can also be called as voice grade or program grade which is a single circuit that is designed or conditioned to provide. Equalization for amplification over a specified band of frequency or for this case of digital data transported via analogue circuit can be one of the quality criteria for such circuit. One of the aspects for mobile quality of service in cellular telephone circuits is the probability of abnormal termination of the call. There is a lot of factor can affect the quality of service of the telecommunication network. From the customer`s point of view looking at this QoS can be describe as common phenomena and its judged by the user. However there is a standard metrics of QoS that can be used by the customer to measure the QoS. The coverage, accessibility and the audio quality is the indicator for this quality. For coverage, strength of the signal is measured using test equipment and this can be used to estimate the size of the cell. For accessibility its about determining the ability of the network to handle successful calls from mobile-fixed networks and from mobile-mobile networks. For audio quality it can be considers monitoring a successful for a period of time for the clarity of the communication channel. All these indicators are used by the telecommunications industry to judge the quality of service of the network. QoS provisioning be managed in the future 4G cellular network Nowadays, cellular network operators across the world have seen a rapid growth of mobile usage. Data usage per subscriber is increasing daily in particular and with the introduction of flat-rate tariffs and more advanced mobile devices. Services provider are moving from a single-service offering in the packet-switched domain to a multi-service offering by adding Value added services (VAS) that are also provided across the mobile broadband access. One of the examples of these Services is multimedia telephony and mobile-TV. These kind services have a different performance requirement in terms of the required bit rates and packet delays or any other examples. However solving these performance issues through over-provisioning typical is uneconomical due to the relatively high cost for transmission capacity in cellular access networks which includes radio spectrum and backhaul from the base stations. 4G broadband wireless technologies such as IEEE 802.16e/m and Third Generation Partnershi p Project (3GPP) Long Term Evolution (LTE) have been designed with different QoS (Quality of Service) frameworks and means to enable delivery of the evolving Internet applications. QoS specifically for evolving Internet applications is a fundamental requirement to provide satisfactory service delivery to users and also to manage network resources. QoS refers to the probability or ability of the network to provide a desired level of service for selected traffic on the network. Service levels are defined in terms of throughput, latency (delay), jitter (delay variation) and packet errors or loss. Different service levels are defined for different types or streams of traffic. To supply QoS, the network identifies different types or streams of traffic and processes these traffic classes differently to achieve (or attempt to achieve) the desired service level for each traffic class. The efficiency of any QoS scheme can be measured based on its ability to achieve the desired service levels for a typical combination of traffic classes. 4G wireless communication systems feel the requirement of transparent and seamless user roaming with end-to-end connectivity. These systems also required higher data rate, higher mobility support and QoS guarantees due to rapid development of wireless and mobile networks. All this requirements is possible for the operators to increase their service portfolio and for the users to experience context-rich and personalized services. Advantages for Subscribers and Operators: Subscribers Know that when the call was busy Users may call for a long time without queuing Easier for users to choose the best mobile phone operator. So, they know which one the operators has the best coverage. Operators Will know when the time is busy and how to solve the problem faster. Always to take the opportunity to improve their network coverage. Disadvantages for Subscribers and Operators: Subscribers Cannot make a call especially during the emergency call. Operators Increase the cost in order to improve the network. Will increase the number of cell in order to handle the large amount of subscribers. SATELLITE COMMUNICATION QUESTION 10 The Very Small Aperture Terminal, VSAT service is becoming more popular in Malaysia. Obtain information on VSAT service operator in Malaysia including examples of application, network topology, user equipments, lease procedure and services offered and their data rate. How can a VSAT system accommodate subscriber that need higher data rate services. Introductions of VSAT A Very Small Aperture Terminal (VSAT) is a two-way satellite ground station with a dish antenna that is smaller than 3 meters (most VSAT antennas range from 75 cm to 1.2 m). VSAT data rates typically range from narrowband up to 4 Mbit/s. VSATs access satellites in geosynchronous orbit to relay data from small remote earth stations (terminals) to other terminals (in mesh configurations) or master earth station hubs (in star configurations). VSAT can be used for data, voice, video or internet applications [10]. It is used to communicate with to link together locations using satellite connectivity. Figure 3.1: A typical VSAT network depicting two way communications from remote terminals through a VSAT satellite to a central hub. MAXIS VSAT VSATs are an ideal means of communication in areas where terrestrial infrastructure is unavailable or unreliable. As such VSAT services are able to bring distant or remote business communities closer by eliminating geographical barriers and challenges that previously existed. This in turn transfers to an increase in productivity and overall cost efficiency for such communities. In addition to providing communication to remote areas, VSATs are also suitable in providing private networks in urban areas for organizations with many geographically dispersed branches that require connectivity to their Headquarters. VSAT services generally offer service reliability and availability that is equal to or higher than terrestrial services. Below are examples of type Maxis VSAT Services that can be used depends on the complexity of the network and the communications requirements; SCPC (Single Carrier Per Channel) Satellite bandwidth is dedicated to a single source. SCPC based design provides a point-to-point technology making it the VSAT equivalent. Supports voice, data, video communications. Advantages; Simple and reliable technologies. Low-cost equipment. Figure 3.2: SkyLine (SCPC) Service hub to remote configuration TDMA (Time Division Multiple Access) Is a channel access method for shared medium network. Allows several users to share the same frequency channel by dividing the signal into different time slots. In Figure 3 (d), all VSATs share satellite resource on a time-slot basis and the remote VSATs also use inroutes for communicating with the hub or TDMA channels. There could be several inroutes associated with one outroute. Several VSATs share one inroute, so it also sharing the bandwidth. Typical inroutes operate at 64 or 128 Kbit/s. Critical to all TDMA schemes is the function of clock synchronization what is performed by the TDMA hub or master earth station. The VSATs may also access the inroute on a fixed assigned TDMA mode, where in each VSAT is allocated a specific time slot or slots. Figure 3.3: Typical SkyNet (TDM/TDMA)-configuration supporting various interactive data applications. ; Summarization of Maxis VSAT Services [6]: Services Service Description Typical Users SkyWayTMVSAT Broadband data and Voice service. Corporations with many branches requiring Broadband Data and telephony. Corporations requiring Internet access. Corporations or communities in remotes areas without telephone connectivity, i.e. plantations, timber camps and remote villages. SkyLine VSAT Dedicated leased line for point-to-point and point-to-multipoint connectivity. Corporations requiring dedicated links for communications between its HQ and branches. SkyLine-Plus VSAT Dedicated leased line with Frame Relay technology for mesh connectivity. Corporations requiring dedicated links for communications between sites within the VSAT network. Gyro-Stabilized VSAT Specialized VSAT service for maritime and offshore oil rigs. Upstream oil and gas corporations Shipping companies. The benefit of Maxis VSAT Services Uniform service quality All sites in the VSAT network receives the same high quality services, whether the location is urban or rural areas. Reach VSAT is a service that available anywhere no matter the place, whether in a remote area, forest or anywhere in the world. High relaibility availability VSAT networks offer high reliability as the points of failure are limited to two points means at any two locations in a communications link. This ensures minimal downtime while the service availability for VSAT networks. Question 11 Global Positioning System, GPS satellite is a navigation satellite that can offer services based on locations. Investigate among the service offered in Malaysia, user hardware and equipments, subscription (if any), and their limitation in term of accuracy. Identify similar service to complement GPS system particularly for mobile and handheld environment. The Global Positioning System (GPS), also known as Navstar, is a satellite based navigation system that can be used by anyone with appropriate receiver to pinpoint location on earth. The array of GPS satellites transmits highly accurate, time coded information that permits a receiver to calculate its exact location in terms of the latitude and longitude on earth as well as the altitude above the sea level [10]. GPS was developed by the U.S Air Force for the Department of Defense as a continuous global radio navigation system that all elements of the military services would use for precision navigation. GPS consists of three parts: the space segment, the control segment, and the user segment [10]. The space segment is composed of 24 to 32 satellites in medium Earth orbit and also includes the boosters required to launch them into orbit [10]. The space segment is the constellation of satellites orbiting above the earth. It contains transmitters which send highly accurate timing information to GPS receivers on earth. The receivers may be used on land, sea or air. Figure 4.1: GPS mapping aids are small enough to be mounted on a dashboard or stashed in a backpackers pack. They are popular with boaters too. Figure 4.2: The GPS space segment Figure 4.2 shows the fully implemented GPS consists of 24 main operational satellites plus 3 active space satellites. The satellites are arranged in six orbits, each orbit containing 3 or 4 satellites. User hardware and equipments GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use triangulation to calculate the users exact location. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the users position and display it on the units electronic map [13]. f A GPS receiver must be locked on to the signal of at least three satellites to calculate a 2D position (latitude and longitude) and track movement. With four or more satellites in view, the receiver can determine the users 3D position (latitude, longitude and altitude). Once the users position has been determined, the GPS unit can calculate other information, such as speed, bearing, track, trip distance, distance to destination, sunrise and sunset time and more[13]. The GPS receivers are extremely accurate, thanks to their parallel multi-channel design. Garmins 12 parallel channel receivers are quick to lock onto satellites when first turned on and they maintain strong locks, even in dense foliage or urban settings with tall buildings. Certain atmospheric factors and other sources of error can affect the accuracy of GPS receivers. Garmin ® GPS receivers are accurate to within 15 meters on average [13]. Newer Garmin GPS receivers with WAAS (Wide Area Augmentation System) capability can improve accuracy to less than three meters on average. No additional equipment or fees are required to take advantage of WAAS. Users can also get better accuracy with Differential GPS (DGPS), which corrects GPS signals to within an average of three to five meters. The U.S. Coast Guard operates the most common DGPS correction service. This system consists of a network of towers that receive GPS signals and transmit a corrected signal by beacon transmitters. In order to get the corrected signal, users must have a differential beacon receiver and beacon antenna in addition to their GPS [13]. GPS satellites transmit two low power radio signals, designated L1 and L2. Civilian GPS uses the L1 frequency of 1575.42 MHz in the UHF band. The signals travel by line of sight, meaning they will pass through clouds, glass and plastic but will not go through most solid objects such as buildings and mountains. A GPS signal contains three different bits of information a pseudorandom code, ephemeris data and almanac data. The pseudorandom code is simply an I.D. code that identifies which satellite is transmitting information. You can view this number on your Garmin GPS units satellite page, as it identifies which satellites its receiving [13]. Ephemeris data, which is constantly transmitted by each satellite, contains important information about the status of the satellite (healthy or unhealthy), current date and time. This part of the signal is essential for determining a position. The almanac data tells the GPS receiver where each GPS satellite should be at any time throughout the day. Each satellite transmits almanac data showing the orbital information for that satellite and for every other satellite in the system [13]. The service offered in Malaysia /GPS Applications The primary application of the GPS is military and related navigation. GPS is used by all services for ships, aircraft of all sort, and group troops. Civilian uses have also increased dramatically because of the availability of many low-cost portable receivers. Most cavitations applications involve navigation, which is usually marine or aviation- related. Hikers and campers and other outdoors sports enthusiasts also use GPS. Commercial applications include surveying, mapmaking and construction. Vehicle location is a growing application for trucking and delivery companies, taxi, bus and train transportation. Police, fire, ambulance and forest services also use GPS. GPS based navigation systems are now widely available as accessories in cars to provide a continuous readout of current vehicle location. GPS is finding new applications every day. For instance, it is used to keep track of fleets of trunks. A GPS receiver in each trunk transmits its position data by way of a wireless connection, such as a wireless local- area network or cell phone. Many new cell phones contain a GPs receiver that automatically reports the location of the user people makes a 999 call. Most location based services will be used for 999 calls, eventually other location services may be developed for cell phones. Not all cell phones use GPS. Some use a unique triangulation method based on the cell phone being able to be in touch with at least three call sites. Finally, GPS receivers are so inexpensive an accurate that they have led to a new hobby called geocaching. In this sport, one team hides an item or treasure and then gives the other team coordinates to follow to find the treasure within a given time. Limitation in term of accuracy Factors that can degrade the GPS signal and thus affect accuracy include the following: Ionosphere and troposphere delays The satellite signal slows as it passes through the atmosphere. The GPS system uses a built-in model that calculates an average amount of delay to partially correct for this type of error. Signal multipath This occurs when the GPS signal is reflected off objects such as tall buildings or large rock surfaces before it reaches the receiver. This increases the travel time of the signal, thereby causing errors. Receiver clock errors A receivers built-in clock is not as accurate as the atomic clocks onboard the GPS satellites. Therefore, it may have very slight timing errors. Orbital errors Also known as ephemeris errors, these are inaccuracies of the satellites reported location. Number of satellites visible The more satellites a GPS receiver can see, the better the accuracy. Buildings, terrain, electronic interference, or sometimes even dense foliage can block signal reception, causing position errors or possibly no position reading at all. GPS units typically will not work indoors, underwater or underground. Satellite geometry/shading This refers to the relative position of the satellites at any given time. Ideal satellite geometry exists when the satellites are located at wide angles relative to each other. Poor geometry results when the satellites are located in a line or in a tight grouping. Similar service to complement GPS system particularly for mobile and handheld environment. GPS-enabled Cell Phones Motorola and Blackberry were the first GPS-enable phones to proliferate the United States. Initially, MotorolaiDEN phones were commonly used for employee tracking on the business-oriented Nextel network. Then GPS enabled Blackberry phones, once used almost exclusively by corporate and government VIPs, began to penetrate the consumer market stimulated by the demand for phones with advanced messaging capability. Next came specialty devices produced under the names of Disney Mobile and Wherify Wireless targeting use by children and elderly. Now in 2009, a variety of GPS-enabled phones and tracking services are available, as you can see from the ads on this page. Locating People in an Emergency Stimulated by the events of 11 September 2001, the demand for enhanced 911 (e911) emergency calling capabilities pushed forward GPS tracking technology in cell phones. At the end of 2005, all cell phone carriers were required to provide the ability to trace cell phone calls to a location within 100 meters or less. Wireless Networks Your phone may have GPS and know exactly where it is, but it cant tell anyone else where you are unless you are connected to a wireless network. Here in the United States, the wireless networks used for GPS tracking are primarily those operated by cell phone carriers. It is not likely that you as an individual will negotiate network access with a carrier. It is more likely that you will select a solution including a cell phone provisioned to communicate in a certain way on a specific wireless network. List below are some carriers recommended for use with GPS cell phones and services. T-Mobile / Cingular / ATT The Global System for Mobile (GSM) communications as adopted by these carriers represents the network with the largest coverage footprint. Roaming agreements between these carriers provide end users with service throughout the country. GSM is also the prominent cellular network abroad. Sprint / Nextel, not so much because of coverage, but because of their emphasis on data. Nextel has created their own data formats and communication protocols for high bandwidth mobile electronics applications.

In task one, the aim is to differentiate between possession of knowledge and practice of knowledge and examine which epistemology B&Q uses throughout their supply chain. B&Q uses possession knowledge whereby it provides all their vendors with a code of conduct guidelines which they need to follow through.However, in the face of risk and uncertainty in an economic crisis, B&Q should adopt practice of knowledge and enabling people to do differently and better. In task two, the statement by Stoneman (2010) means that trust and power are the main factors that drive product, process and organizational innovation. For B&Q, due to their power as the distributor, they are able to develop and lay down the process and procedures that all their vendors need to adhere to. However, in an economic crisis, its regimental practice may ot work as uncertainty disrupts the flow of the procedures. 1. TASK ONE 1. 1 Introduction The studies on knowledge and its characteristics have long been explored and discussed in the business and supply chain world. With the emergent of technology and innovation, the possession and practice of knowledge has become more essential in this â€Å"knowledge society† (Nonaka, 1994; Bell, 1973; Drucker, 1968; Toffler, 1990). But what is knowledge and how does an organization activate and generat e knowledge?Knowledge is defined as â€Å"awareness, consciousness, or familiarity gained by experience or learning† (knowledge, n. d) which are the ways people in a social situations would understand and make sense of where they are and what they are doing. When knowledge is conducted and embraced in an organization, it will result to a group of people who develop shared beliefs, behaviours and routines that shape organization capabilities. Experts such as Polanyi (1966), Nonaka (1994) and Cook and Brown (1999) divide knowledge into two categories called tacit knowledge and explicit knowledge.Tacit knowledge is associated with the skills or know-how that people developed through their own experience in specific contexts. Whereas explicit knowledge is something that has been codified, written down or spelled out and is communicable across context. 1. 2 Possession and practice From the word possession itself, one can understand that it is about the knowledge that people have i n their mind (Cook and Brown, 1999). Blackler (1995), and Cook and Brown (1999) refer possesion of knowledge as â€Å"knowledge† and practice of knowledge as â€Å"knowing†.Knowledge is a mental or cognitive capacity which is hierarchical in nature and comprises of data, information etc. moreover, possession of knowledge is a personal property where people render meaning from subjective experiences, perceptions and previous understanding. As human minds are individually unique, hence different people may perceive and intepret the same information or data differently. Meanwhile, practice of knowledge sees knowledge as something that it developed through social interaction such as project work, group assignment or group discussion.When people practice knowledge, they convert tacit knowledge into explicit knowledge, thus transferring knowledge from one person to another. This is done through sharing stories, experiences or creating norms to a group of people hence enablin g the experience of an individual to be related to a wider community. 3. 3 B&Q case B&Q plc works with many vendors such as Kingfisher Asia (KAL) who supply products to B&Q. Hence to manage their vendors and ensure processes and procedures are followed, B&Q come up with code of conduct (B&Q Operational Standards for Supply Chains) for all their vendors.The code of conduct is based on the international labour and envirnmental standards set by the International Labour Organisation (ILO) Conventions which factories and worksites of all vendors throughout the world need to comply to. In summary, vendors need to let B&Q have full visibility of the enitre supply chain and fulfill and obey the code of conduct criteria at all facilities. Any failure to meet the nine Critical Failure Points (CFPs) will result in B&Q not buying or purchasing their products.Through this code of conduct, we can deduce that B&Q adopts a possession of knowledge rather than practice of knowledge. B&Q receives know ledge about labour and environmental guidelines from ILO conventions and uses the basic context to write down or capture in an information technology (IT) system which is then made available as an organizational resource – B&Q Operational Standards for Supply Chains. This is in contrast of having a group discussion with the vendors and seeking their opinions and views on how to create a better working environment for the workers (practice of knowledge).For example, Baer (1987) and Abbott (1988) explained that in order to defend their position, occupational groups such as doctors would write down or ‘black box’ their skills and knowledge which is then used by others as guidelines or instructions to follow. B&Q is following the same concept as they wish to guard their position as a responsible organization or employer where the rights of all workers throughout the world are respected and protected. Thus, this results to an encoded knowledge (Blackler, 1995) for the vendors as information is transmited through the code of conduct.Unlike an individual or specialist ‘black box’, the construction of the code of conduct requires the involvement of a group of people. This method of knowledge creation follows Nonaka’s SECI framework where it is a spiralling process of interaction between tacit and explicit knowledge (Nonaka,1994; Nonaka & Toyama, 2003). The SECI framework consists of four knowledge conversion processes; Socialization, Externalization, Combination and Internalization; which can be seen in Figure 1. The breakdown for B&Q case is as follow: 1.Socialization – The ILO standards which was made known to the B&Q management assist them to create their own knowledge or set of standards which vendors are to adhere. 2. Externalization – B&Q management then decides to have their on set of guidelines in accordance to ILO standards and form a group to write down the code of conduct. 3. Combination – We beli eved that during the process of writing down the code of conduct, B&Q managerial level will each provide inputs and opinions based on the organization’s mission and values on what and how to write down.Once drafted, the Head of Human Resource Department will read it through and request for any necessary adjustments. Once finalized, the Chairman or Head of B&Q will give the approval to codified and disseminate the code of conduct to all the vendors. 4. Internalization – Vendors will then read the instructions and ensure all CFPs are met. For any areas which fail to comply, site management of the vendors will then follow the guidelines to make changes and improvements. Figure 1: SECI model of knowledge creation Source: Nonaka & Toyama (2003)However, Nonaka SECI framework downplays the difference of interest, power and political dynamics which people and organizations face everyday. Thus, during an economic crisis, B&Q may approach innovation differently due to the uncert ainty and adversity faced in a crisis. According to Tsoukas (1996) and Schauer (1991), even though organizations can make assumptions and obtain knowledge from previous economic crisis where similar conditions are seen, the formulate strategy may not work perfectly according to what the organizations believed as there are still uncertainty.Meaning to say, a strategy used in a crisis five years ago may not generate the same result due to the difference in technology, people’s mindset and other relating conditions. B&Q need to adopt practice of knowledge during a crisis as information may not be readily available since people and other organizations are wary and may not disclose essential information in order to survive the crisis. With competition between rival organizations getting tougher, B&Q needs to learn, practice and embodied skills and knowledge which increases their chance of survival (Barnett & Burgelman, 1996).As mentioned by Hitt et al (2007), a multilevel research approach to encourage employees to have better understanding of the strategy implemented by B&Q management. Hence, B&Q through providing an enabling context, B&Q allow its employees to do things differently and better. For example, when selecting their vendors, B&Q can not just rely on which vendor is able to adhere to its code of conduct. B&Q also need to look into the pricing, capability and other characteristic of the particular vendor.B&Q vendor management team need to have further dicussion with sales, procurement and operations team to gain their opinions and views on which vendors to select. With the current vendors, B&Q need to adopt open communication and discuss with them on how the crisis is affecting their perfomance and compliance towards the code of conduct. Another example is due to the crisis, a vendor had to lay off several staff and workers due reducing their headcount. Hence in order to meet B&Q rders, the vendor’s workers may need to work extra hours whic h is over the local law. Through discussion, B&Q may allow the vendor to carry out the new process until the economy stablize and the vendor is able to employ more workers. 3. TASK TWO 3. 1 Introduction Stoneman (2010) mentioned that â€Å"product, process and organizational innovation are socially and politically mediated processes†. This means that through social relationship and even political standing in an organization; product, process and organizational innovation are being conceptualized.Jackson (2001) noted that the real-world issues and situations do not match up to traditional disciplinary boundaries due to the inequality in the capitalist world. Therefore, trust and power play an essential role in the development of knowledge and innovation. Internally at B&Q, their managers may see themselves as the authority towards process and organizational innovation. For example, a manager has the power to decide on how his department should be run in order to meet the depar tment and organization goals.And through his relationship and interaction with the staffs, he may perceive a staff as capable if able to follow the process and excel in it. Hence, to gain trust and acknowledgement, employees compete and motivate each other to do better at what they do and also provide suggestions to the manager on improving certain situations or issues. As highlighted by Hardy and Dougherty (1997), depending on the organization’s culture and its board of management, resource power and process power can either work against or aligned with innovation.However, without meaning and a direction to support the need for innovation, people will notbe motivated to innovate. For example, the warehousing staffs at B&Q may face difficulties in picking the correct product. Thus, with its power, the warehouse manager can arrange a group discussion with the warehousing team leaders and their IT department to create a new process whereby the product are bar-coded and connecte d to a system which will provide the product information when it is scanned.Externally, when working with their supply chain members such as customers and suppliers, B&Q managers can use either its power or trust to ensure compliance are met by the suppliers and customers continue to purchase from B&Q. For example, the board of management has the authority to continue or discontinue the services of a vendor depending on its compliance and performance. However, during an economic crisis where risk and uncertainty are faced, B&Q managers may react to similar situation or innovation differently.B&Q decisions on innovation, processes and products are affected by four types of distance – time, technological, social and cultural. 3. 2 Time distance Due to the changes in time, environment and conditions, certain processes or procedures that B&Q managers created may not be applicable in an economic crisis. Moreover, the decisions B&Q managers made in a previous crisis are also not ap plicable even though the conditions are similar because there is still uncertainty whether the outcome would be the same.The finance department will be more guarded on the expenses and budget thus setting a more thorough process of other departments to ensure waste are minimized and costs are low. In a study done by Hardy and Dougherty (1997), innovators or managers in an anti-innovation environment would solve their problems through methods and ways which hamper innovation whereas in a pro-innovation environment, innovators are able to incorporate the organization’s resources, processes and meaning to develop an more suitable and effective product.Thus, in relation to the crisis, B&Q managers may tackle a deparment issue by pushing away the problematic function and work its way around it. 3. 3 Technological distance As ICT becomes highly advanced, B&Q need to be selective of the information and tacit knowledge that is available widely. This is because not all tacit knowledge is applicable to B&Q’s strategy and that an overflow of information will result to overloading and poor decision making. Through market and technology knowledge, innovators are able to examine problems, communicate and collaboratively develop new products for the organization (Dougherty et al, 2000).However, in an economic crisis, technology knowledge that is necessary for innovation may not be readily available or cost effective to the organization. Faced with uncertainty, B&Q board of management may decide to take on a survival mode concept and develop process such as budget control to restrict unnecessary cost and waste. Thus, if an innovator in B&Q requires a certain technology to assist in its development of new product, he need to go through many levels of strict procedures in order to attain approval. 3. 4 Social distanceDuring an economic crisis, organizations face many problems and situations as they try their hardest to survive and go through the crisis without a m ajor disruption or impact. Due to the uncertainty and risk, managers need to respond quickly and effectively. Even in a crisis, Jackson (2006) noted that managers need to ensure their processes are efficient and effective, staffs are motivated and knowledge is created and enhanced. This is to ensure that the organization is constantly better than their rivals thus surviving the crisis.While ICT and innovation should still move on in a crisis; being a regimental organization; B&Q managers follow routine and have the power to make innovation unlawful through rewarding short-term results, punishing mistakes and even not rendering the support needed for innovation (Hardy & Dougherty, 1997). Not only does this kills innovation in B&Q, the staff would also be less motivate to innovate as they unable to relate a specific project with B&Q’s strategy (Van de Ven and Polley, 1992; Hardy and Dougherty, 1997; Dougherty & Heller, 1994).Hence, B&Q board of management need to re-evaluate it s organization strategy and procedures if it wishes to maintain in the industry. Jackson (2006) suggest organizations to adopt creative holism which is a set of guidelines that are multi-paradigm, multi-methodology and multi-method in nature. Through holism, organizatons look at the situation at a macro and organizational level, thus assuring that the departments are connected and performing together as a whole.Dougherty et al (2000) explained that since organizational knowledge and learning involves many different processes, a focal point or objevtive is essential to ensure one is taking the right path. Pelz and Andrews (1966) recognized that the efforts to combine and link market and technology knowledge across and throughout the organization is often met and filled with tensions. Thus, B&Q need to incorporate these two factor and be less rigid if it wishes to produce and gain new ideas, products and processes (Weick and Westley, 1996). 3. 5 Cultural distanceKingfisher plc, the pa rent company of B&Q, is a United Kingdom (UK) based retailer that offers do-it-yourself (DIY), home decorations and home improvement products to their 6 million customers (Kingfisher, 2012). To meet their international market and demand, Kingfisher plc has overseas sourcing offices in India and Poland that act as a supplier to B&Q. To ensure these strategies and structure is maintain in other country, Kingfisher plc has to train its overseas employees, make them understand and cultivate the Kingfisher plc working culture.However, this will be a tough challenge for example, in India due to the poor education and different socio-culture. Thus, Kingfisher plc needs to accommodate its Western working culture with India working culture, but without losing its main mission and strategy. To ensure this is executed properly, Kingfisher plc needs to obtain a specialist in the Indian market and culture. An economic crisis affects countries differently, depending on where the crisis originates .However, due to globalization, a crisis in the European Union (EU) nations will have a ripple effect, thus affecting neighbouring countries and countries that depend on the EU economy and market. Likewise, if an economic crisis hits India where one of B&Q suppliers is located at, B&Q need to gather information and data from news reports and the India supplier’s representative, and analyse the data before making a decision on how to overcome the crisis and what B&Q should do to ensure that the crisis in India do not disrupt the entire supply chain.To ensure accurate and timely information and knowledge is recevied, Swan and Scarbrough (2005) suggest organizations to adopt a networked innovation process where the innovation procedures is collaborated in the network arrangements within and between organizations (Alter & Hage, 1993; Owen-Smith & Powell, 2004; Powell et al, 1996). B&Q needs to view networks as a means of communication where knowledge and information are dissemina ted (Swan & Scarbrough, 2005) and thus, adopting a open sharing concept where individuals and groups are allow to interact and exchange knowledge and information. 4.
