W.M Morrisons Plc and Oracle Essay Example for Free

W.M Morrisons Plc and Oracle Essay In March 2004, WM Morrisons PLC completed the takeover of Safeways with a ? 3bn offer of cash and shares, this deal instantly made Morrisons a nationwide company and the 4th largest retail supermarket in the UK with its total store count jumping up from 199 to 403 currently, after the purchase of stores from the Somerfield/Cooperative group. With â€Å"every week 9 million customers pass through our doors and 124,000 colleagues across the business work hard each day† Morrisons (N/A), this is a far cry from its humble beginnings in 1899. In 1899 William Morrison, an egg and butter merchant, started he’s selling from he’s stall in Bradford Market. Jump forward to 1958 and William Morrison’s son Ken, company chairman from 1958-2008, took control of Morrisons, from he’s ailing father, and moved the company from market stalls and opened a small town centre shop in Bradford the first of its kind in Bradford to offer self service and have products are priced. In 1961 Morrisons opens its first ‘supermarket’ converting a cinema in 5,000sq ft of retail space. By 1967 Morrisons becomes a public company after significant growth and expansion, with the share offer being oversubscribed with more than 80,000 investors trying to purchase shares. Now building infrastructure with the completion of a distribution centre in Wakefield completed in 1988 and expanded in 1990. But further expansion outside of Bradford and Northern England does not happen until 1998 when it opens its first store in Southern England, located in Erith, Greater London. Followed by its inclusion in the FTSE 100 in 2001 it’s acquisition of Safeways in 2004. To its meteoric growth in that period of 2004-2009 where Morrisons became one of the ‘Big Four’ supermarket chains and winning various food retail awards such as Food Retailer of the Year and picking up multiple awards at The Grocer awards and its total stores jumped from 119 to 403. It was clear to many analysts and its competitors that Morrisons would suffer from growing pains in all aspects of its business with many questions being asked of Morrisons, such as; Did Morrisons have the infrastructure in place to support such rapid expansion? †¢Was its current business model suitable for such large scale revamp? Could its current operations support the strain of this expansion? Would Morrisons have to change its business image for being the ‘food specialist for everyone’ to compete effectively with the ‘big four’? This case study will focus on Morrisons infrastructure, specifically it’s IT systems and will look at the decision making process that went into and led to Morrisons deal with Oracle in 2008 to â€Å"implement a complete Oracle retail suite of merchandising, planning and stores applications, plus the Oracle E-Business Suite for financials, HR/payroll and manufacturing. IDG (2008). It will also look at the key challenges companies face when implementing such wide sweeping changes to its IT systems and review the outcomes of this system against Morrison’s original strategy. Firstly, with the increasing developments in IT systems it is becoming more common for companies of all sizes to utilize some form of IT in their business, from a sole trader compiling monthly sales figures to a big plc like Dell who gener ate and complete sales completely from an online setting. When it came to Morrisons making significant changes to its IT systems it had a wealth of information and real examples to follow or in the case of J Sainsburys with its rushed and failed ? 290million implementation of IT systems aimed at lowering costs, successful business model change in regards to Dell Inc and it’s change to operate completely online which help massively in stock control technology while dealing with custom orders.

Pseudomonas Aeruginosa: Virulence and Pathogenesis Issues

Pseudomonas Aeruginosa: Virulence and Pathogenesis Issues Pseudomonas aeruginosa is a gram negative, motile, aerobic rod shaped bacterium which can occur as singles, in pairs and occasionally in short chains. P.aeruginosa is a ubiquitous organism which can proliferate under the sparest conditions such as sinks, toilets, cosmetics, vaporisers, inhalers, respirators, and anaesthesiology and dialysis equipment. Infected patients and staff are also potential primary sources of infection (2). P.aeruginosa is a major opportunistic pathogen of the immunocompromised causing a wide range of nosocomial infections. These include infections of burn, post operative wounds, urinary tract (especially in patients with catheters), ears and eyes. Infection frequently leads to sepsis and deaths can occur (3). This organism is associated with the greatest morbidity and mortality in cystic fibrosis (4) and is prevalent among patients with burn wounds and intravenous drug users (5, 6). P.aeruginosa is able to persist and multiply in moist environments and on mos t pieces of equipment in hospital wards. This is of importance in cross infection control (4). P.aeruginosa is the most important, resistant and dangerous organism infecting burn patients (7). It is the fifth common pathogen among hospital microorganisms and causes 10% of all hospital acquired infections (8). The rate of commensalisation increases as the duration of hospital stay increases (9). Epidermiologically, P.aeruginosa is ranked as the fourth cause of nosocomial infections in the United States (10). A study on various clinical isolates was conducted in Afghanistan at the Post Graduate Medical Institute (PGMI) Hayatabal Medical Complex to ascertain the prevalence and antimicrobial susceptibility patterns of P.aeruginosa infections. Among the positive isolates, 6.67% were P.aeruginosa with the highest rate of infection observed in orthopaedic ward (24.61%) and 0PD (20%). The highest percentage of P.aeruginosa isolates were observed in pus (57.64%) (11). Pseudomonas aeruginosa is resistant to many antimicrobial agents and has therefore become dominant and important when the more susceptible bacteria of the normal flora are suppressed (1). With the widespread use of quinolones both in the hospital and in the common setting, drug resistant P.aeruginosa isolates have emerged and continue to escalate rapidly (12). The antimicrobial agents are losing their efficacy due to indiscriminate use of antibiotics, lack of awareness, patient non compliance and unhygienic conditions (11). Like most gram negative bacilli, P.aeruginosa has been reported to have developed resistance to commonly used antibiotics and disinfectants. It was originally sensitive to Carbernicillin, piperacillin, Gentamicin, ciprofloxacin and other drugs. However it is now resistant to these antibiotics (13, 14). The virulence factors associated with P.aeruginosa infections include cytotoxin production, the organisms ability to form a biofilm, produce gelatinase, elastase an d alkaline protease. These cause the destruction of connective tissue and degradation of host immunological factors (15, 16). The primary aim of this study is to determine the prevalence of P.aeruginosa in wound infections and its sensitivity to commonly used antibiotics in inpatients at Parirenyatwa Group of Hospitals. PSEUDOMONAS AERUGINOSA Pseudomonas aeruginosa is one of the most common Gram-negative microorganisms identified in the clinical specimens of hospital admitted patients. It is a rod that measures about 0.6 2Â µm and is motile by means of a single polar flagellum (1, 18). P. aeruginosa is noted for its metabolic versatility and its exceptional ability to colonize a wide variety of environments and also for its intrinsic resistance to a wide variety of antimicrobial agents. It is an obligate aerobe that grows well at temperatures between 37-42Â °C. Due to its ubiquitous nature, P. aeruginosa grows readily on any type of media (1). On Blood agar they are often ÃŽ ²-haemolytic while on MacConkey agar they produce pale colonies because they do not ferment lactose. P.aeruginosa is oxidase positive (17). Pseudomonas aeruginosa is well known for its production of two soluble pigments, pyocyanin which is a non-fluorescent bluish pigment and the fluorescent pigment pyoverdin, which gives a greenish colour to the media. P. aeruginosa also produces a sweet grape-like odour due to the production of 2-aminoacetophenone (1, 17). PATHOGENESIS P. aeruginosa is pathogenic when introduced to areas lacking normal host defences for example when there is tissue damage and during cancer therapy where there is neutropaenia (1). P.aeruginosa is a major opportunistic pathogen of the immunocompromised causing a wide range of nosocomial infections. These include infections of burn, post operative wounds, urinary tract (especially in patients with catheters), ears and eyes (in users of extended-wear soft contact lenses). Infection frequently leads to sepsis and deaths can occur (3). This organism is associated with the greatest morbidity and mortality in cystic fibrosis (4) and is prevalent among patients with burn wounds and intravenous drug users (5, 6). It produces cytotoxins, proteases and haemolysins. Isolates from patients with Cystic fibrosis produce a polysaccharide, alginate. The alginate, pili and outer membrane mediate adhesion to host epithelia (19). VIRULENCE FACTORS The ability of Pseudomonas aeruginosa to cause a wide range of infections is due to its ability to produce a number of cell-associated (adhesions, alginate, pili, flagella and lipopolysaccharide) and extracellular (elastase, exoenzyme S, exotoxin A, haemolysins, iron binding proteins, leukocidins and proteases) virulence factors. These mediate a number of processes including adhesion, nutrient acquisition, immune system evasion, leukocyte killing, tissue adhesion and blood stream invasion (20, 21). CELL-ASSOCIATED VIRULENCE FACTORS P.aeruginosa requires a breach in first-line defences to initiate infection. This can result from alteration of the immunologic defence mechanisms for example in chemotherapy-induced immunosuppression and AIDS, disruption of the protective balance of mucosal normal flora by broad-spectrum antibiotics, or breach of normal mucosal barriers for example trauma and burns (21, 23). Adherence of P. aeruginosa to host epithelium is mediated by type 4 pili, that extend from the cell surface (1, 22). Flagella, primarily responsible for motility may also act as adhesins to epithelial cells (23). Lipopolysaccharides are responsible for endotoxic properties of the organism while the exopolysacharride is responsible for the mucoid colonies from patients with Cystic fibrosis (1). EXTRACELLULAR VIRULENCE FACTORS These are extracellular products produced by P. aeruginosa that can cause extensive tissue damage. They include exotoxin A, exoenzyme S, elastase, alkaline protease but the contribution of a given factor varies with the type of infection (24). Exotoxin A catalyses ADP-ribosylation and inactivation of elongation factor 2, leading to inhibition of protein biosynthesis and cell death (25). It is also responsible for local tissue necrosis (1). Exoenzyme S is also an ADP-riboslytransferase that ribosylates GTP binding proteins resulting in direct tissue damage (26). Phospholipase C and rhamnolipid are haemolysin produced by P. aeruginosa. They breakdown lipids and lecithin and both have cytotoxic effects (27). Pseudomonas aeruginosa also produces toxins which include Las B elastase, Las A elastase and alkaline protease (28). Las A elastase and Las B elastase have elastolytic activity. Elastin is a major component of lung tissue and blood vessels. Las B elastase is a zinc metalloprotease while Las A is a protease. Alkaline protease lyses fibrin (29). BIOFILMS Pseudomonas aeruginosa is also able to form biofilms. Biofilms are complex communities of surface-attached aggregates of microorganisms embedded in a self-secreted extracellular polysaccharide matrix or slime (alginate) (30, 31). These act as efficient barriers against antimicrobial agents (aminoglycosides, ÃŽ ² lactamases, fluoroqunilones and disinfectants) and the host immune system resulting in persistent colonisation and loss of action at the site of infection (32, 33). CELL TO CELL SIGNALLING Cell to cell signalling systems control extracellular virulence factors required for tissue invasion by P. aeruginosa. THE LAS CELL TO CELL SIGNALLING SYSTEM The Las cell to cell signalling system regulates the expression of Las B elastase (34). It regulates Las B expression and is required for optimal production of other extracellular virulence factors such as Las A elastase and exotoxin A (35). THE RHL CELL TO CELL SIGNALLING SYSTEM The rhl cell to cell signalling system controls the production of rhamnolipid. The system regulates the expression of the rhl AB operon that encodes a rhamnosyltransferase required for rhamnolipid production. It is also important for Las B elastase, protease, pyocyanin and alkaline transferase production (36). ANTIMICROBIAL REACTIVITY OF P. AERUGINOSA Like most gram negative bacilli, P.aeruginosa has been reported to have developed resistance to commonly used antibiotics and disinfectants. It was originally sensitive to Carbernicillin, piperacillin, Gentamicin, ciprofloxacin and other drugs. Degrees of cross-resistance between these agents have been reported however (13, 14). Treatment of infections by P. aeruginosa is often difficult because of its virulence and limited choice of antimicrobial agents. P. aeruginosa has the capacity to carry multiresistance plasmids, and this feature has led to the appearance of some strains that are resistant to all reliable antibiotics (37). In a study carried out at the Post Graduate Medical Institute Hayatabad Medical complex in Afghanistan on the prevalence and resistance pattern of P. aeruginosa against various antibiotics, the highest resistance was observed against ampicillin, ampicillin/ sulbactam, co-amoxiclave and ofloxacin and least resistance was observed against amikacin. Similarly t he MIC for ampicillin, ampicillin/sulbactam and co-amoxiclave against clinical isolates of Pseudomonas aeruginosa was also high (11). A similar study carried out at Dhaka Medical College Hospital in 2006 showed that almost all of the P. aeruginosa isolates were resistant to cefixime and co-trimoxazole, majority were resistant to ceftazidime, gentamycin and ciprofloxacin. The result of the study showed that imipenem is the most effective drug against P. aeruginosa, followed by amikacin and ciprofloxacin (39). MECHANISM OF ACTION OF COMMONLY USED ANTIBIOTICS The commonly used antibiotics in the treatment of P. aeruginosa infections are Aminoglycosides (for example Gentamicin and amikacin), Penicillins (such as cabernicillin), Quinolones (for example Nalidixic acid, ciprofloxacin and levofloxacin), Cephalosporins (ceftazidime) and Carbapenemes (meropenem and imipenem) (37). Penicillins, Cephalosporins and Carbapenemes inhibit bacterial cell wall synthesis. They are ÃŽ ²-lactam agents. Aminoglycosides and Tetracyclines are inhibitors of protein synthesis. Quinolones are inhibitors of bacterial nucleic acid synthesis (17). RESISTANCE TO ANTIBIOTICS The antimicrobial resistance conferred by P. aeruginosa is due to mutations in the organisms genetic material. No single mutation is responsible for multidrug resistance. Mutations to topoisomerase 2 and 4 confer fluoroquinolone resistance. Derepression of the chromosomal AmpC ÃŽ ²-lactamase reduces susceptibility to penicillins and cephalosporins. Up-regulation of MexAB-OprM compromises the fluoroquinolones, penicillins, cephalosporins and it also enhances resistance to many other drugs that lack useful anti-pseudomonal actions (38). 1.2 STATEMENT OF THE PROBLEM Considering the ability of Pseudomonas aeruginosa to persist and multiply in moist places and in most pieces of equipment in hospital wards (4), antimicrobial resistance is a growing concern. This is attributed to the fact that the organism is able to withstand conditions such as high temperature and high concentrations of salts and antiseptic (10). It is therefore imperative to constantly evaluate the pathogenesis and sensitivity patterns of P.aeruginosa so as to prevent further spread and recurrence of infection in the hospital set up. 1.3 HYPOTHESIS Null Hypothesis (H0) The prevalence of P. aeruginosa in wound and pus swab specimens at Parirenyatwa hospital is 6.7%. Alternative Hypothesis (H1) The prevalence of P. aeruginosa in wound and pus swab specimens at Parirenyatwa hospital is greater than 6.7%. 1.4 OBJECTIVES The aims of this study are: To determine the prevalence of P. aeruginosa in wound and pus swab specimens of patients admitted at Parirenyatwa hospital. To determine the antimicrobial susceptibility patterns of the isolates.

The bluetooth technology

The bluetooth technology Abstract: Bluetooth Technology has been widely spreading every single day due to its availability in most of the electronic devices that are dominant nowadays. As any other technology, when widespread, will have a huge impact on the users and societies. In our study, we will search the impact of Bluetooth technology on the society. To get a realistic knowledge, a survey contains 10 questions on our topic was conducted. 100 people from Multimedia University and Limkokwing University were randomly chosen to participate in our survey. In addition, we relied on other sources such as the internet to collect information regarding our topic. From our study we have found that, the spreading of the Bluetooth technology has made life easier. As any other technology Bluetooth is, sometimes, used in a negative way and consequently has a negative influence. Acknowledgement: We would, firstly, like to thank our God who gave us the ability to accomplish this research. Secondly, many thanks to our EHM 3066, Engineers and society, subject lecturers who have been giving us a very good example of diligence and hard work. We send our gratitude to the participants who have participated in our questionnaire and given us from their precious time. Thanks to our families, friends and all our beloved people who has always given us the inspiration to be successful. We would finally thank our institution, the Faculty of Engineering (FOE), Multimedia University. 1.0 Introduction: Technology is considered to be the mount to climb up and attain the desired degree of development of a society. Man has been trying to facilitate his life through inventions and innovation. He first invented the â€Å"wheel† and hasnt stopped so far. He lately invaded other planets. Telecommunication means, when computerized, played a very important role in spreading data which enabled scientists utilize the outcome of other scientistsresearches and that lead to more and more advancement in various fields of science and thus more technical devices. These devices didnt have the present shape. A lot of effort was exerted in the process of betterment with regard to performance, size and ease of use. This trial is to have a clear idea of how Bluetooth technology is affecting the society and our lives. 1.1 Overview of Bluetooth: In the striving for reduction of cables between computers and their connected units, Ericson Mobile Communication, in 1994, started the project named and named it Bluetooth. What is Bluetooth? Bluetooth is the name of a new technology that is now becoming widespread on a commercial basis. It promises to change significantly the way we use machines. Instead of using cables to transmit data between components of a PC,for example, the printer, the mouse and so on, a small and cheap radio chip to be plugged into these components will do the job. In short it is a Cable-replacement technology. The name was first used as a code name, but it stuck as time passed. It is named after the 10th Danish King, Herald Bluetooth, who had united Scandinavian Europe at a time it was severely divided. The founders of the Bluetooth technology found the name fitting as the Bluetooth technology is able to unite various industries like cellphone, computing and automotive markets. By Bluetooth technology one is able to simplify and combine several forms of wireless communication into a single, safe, power-saver, inexpensive, globally available radio frequency. 2.0 Bluetooth Mechanism: By embedding short-range transceivers that are inexpensive and tiny, into new electronic devices that are available nowadays, Bluetooth achieves its goal. In addition to three voice channels, Bluetooth can transfer data at data transferring speed up to 721 Kbps. As Bluetooth operates on radio band, at frequency of 2.45 GHz, that is unlicensed and globally available, people or â€Å"international travelers† have no obstructions to use Bluetooth-enabled equipment. Moreover, Bluetooth units might be either externally adapted or built into electronics devices. E.g. in a personal computer, Bluetooth devices can be built into the motherboard as a PC card or on the other hand it can be used as an external Bluetooth adaptor through connecting it to a USB port. From the IEEE 802 standard, each Bluetooth device has its own 48-bit address. One feature is that connections are not only point to point, but they can also be multipoint connections. Usually, Bluetooth devices have a maximum ra nge of connection up to 10 meters. However, by increasing the power, the range of connection might be extended to 100 meters. Bluetooth devices have a technique called frequency hopping. The main purpose of this technique is to protect the devices from radio interference. The mechanism of the technique is that Bluetooth devices change arbitrarily their frequency maximally 1600 times/s. when an error occurs, it will be immediately corrected by the three complimentary error correction schemes that any Bluetooth device has. Bluetooth devices are also provided with built in verification and encryption. When Bluetooth devices are in a â€Å"hold† mode they consume approximately 30 micro Amperes from the battery of the electronic devices, such as cell phones and laptops, while they consume a range of 8 to 30 milliamps, less than one tenth of a watt, when they are in the active transmission mode. Moreover, only 0.3 mA are consumed by the radio chip, when in a standby mode, which means that its less than 3 % of the power that is used by a mobile phone. Also, the radio chip has an excellent power-saving feature that is as soon as the traffic volume lessens, the chip shifts automatically to a low-power mode. The above indicates that Bluetooth devices do not drain precious battery life. But beyond un-tethering devices by replacing the cables, Bluetooth devices can form a small and private ad hoc grouping of devices that are away from fixed network infrastructures by providing universal bridges. These bridges are to connect between a device, data networks and a peripheral interface. Furthermore, noisy radio frequency environment does not affect Bluetooth devices since they are designed to use a scheme called frequency hopping scheme and as well as a fast acknowledgment in order to make the link active and strong. After sending or receiving a packet, Bluetooth radio modules keep away from interference from other radio signals by jumping â€Å"hopping† to a new frequency. The Bluetooth radio uses shorter packets and jumps â€Å"hops† faster than other systems that are operating in the identical frequency band the thing that makes the Bluetooth radio more active and stronger than other systems. In addition, these fast hopping from a frequency to another an d the short packages decrease the impact of domestic microwave ovens. Random noise may affect long-distance links. However, Forward Error Correction (FEC) is used to eliminate this impact. The encoding is, then ideal for an uncoordinated environment. At the bit level, Bluetooth security is guaranteed. Users can control the authentication by using a 128 bit key where radio signals are coded with 8 to 128 bits. The Bluetooth radio transmissions match the safety standards that are required by the countries where the technology is used with respect to the effects of radio transmissions on the human body. Bluetooth enabled devices emissions are less than those from industry-standard cordless phones. Also, Bluetooth module do not interfere, cause harm or even affect public or private telecommunications network. 2.1 Bluetooth Operation Modes: A feature of Bluetooth technology is that, once the Bluetooth devices come in range of each other, they will instantly form networks between each other.Another feature is that a number of devices can be connected together via Bluetooth in an ad hoc form. This feature is technically known as â€Å"Piconet†. In a piconet two or more devices can be connected together. A scatter net can be formed by multiple independent and non-synchronized piconets. Moreover, any device that is in a piconet can be a member of another piconet through a technique called time multiplexing. This techniques mechanism is to share the time suitably, thus a device can be a member of two or more piconets. As Bluetooth system supports multi-point connections as well as point to point connections, Bluetooth devices can be connected to a maximum of another 7 points, a point to multipoint connection. Every piconet has different frequency hopping sequence and hence a number of piconets may be created and linked together. All users that are sharing onepiconet are synchronized piconets hopping sequence. A Bluetooth device uses different hopping sequence when the device is connected to two or more piconets where a piconet starts with 2 connected devices, e.g a laptop and a mobile phone, and may grow to 8 connected devices . All Bluetooth devices have the same implementations. However, there are two types of unites in a piconet which are master units and slave units.A master unit is the unit which synchronizes the other devices by its clock and hopping sequence, where the other devices in the piconet are called slave units. In order to differentiate between units participating in the piconet, a 3-bit MAC address is used. When a unit does not have a MAC address, it is called a park unit. Park units are usually synchronized. Anyway, since parked units have an 8 bit address, a maximum of 256 parked units may be existed. 3.0 Bluetooths positive impact: 3.1 Huge Impact: What could the practical use of Bluetooth be on Society? Well, it is unlimited and depends on the way it is used. From a practical viewpoint, we can adapt all computerized Have a look at the list below! Printers Desktop and laptop computers Modems LAN access units http://www.sysopt.com/img/icons/war_ex.jpghttp://www.sysopt.com/img/icons/log_v450.jpgFax devices Phones and pagers Headsets Keyboards joysticks Notebook computers Practically, most of the digital devices can be a part of the system of Bluetooth. The dynamic of Bluetooths connectivity nature has the ability to replace USB (Universal Serial Bus). A Bluetooth-mouse can be in existence by using the improved plug-and-play-systems. The installation can take effect after the operating system is rebooted. 3.2 Bluetooths Applications 3.2.1Bluetooth and the Internet One of the most important advantages of Bluetooth is that it enables you to connect a device provided with internet connectivity to another device that is not. E.g. you might connect your hand phone that has a built-in Bluetooth to your laptop that has a Wi-Fi via Bluetooth connection. Then, via you laptops Wi-Fi, if exists, to a Wi-Fi router. Once your laptop is connected to the internet you can enable your hand phone to be connected to the internet as well. Moreover, this example goes correctly to most of the devices that have Bluetooth technology not only hand phones.   Ã‚  Ã‚  Ã‚  Ã‚  Buying a device that has a Wi-Fi or buying another that has a Bluetooth technology is sometimes a confusing choice. One may think that by choosing Bluetooth he/she will not be able to connect to the internet and in this case choosing a Wi-Fi would be better.   Ã‚  Ã‚  Ã‚  Ã‚  However, this is not such a really correct choice. Since, from the above example, you can modify your device to get connected to the internet via the Bluetooth technology purchasing a device that has a Bluetooth technology is a better choice as you can get two technologies in one ; internet connectivity (the function of Wi-Fi is achieved) and Bluetooth technology. 3.2.2 Some Other Applications: A Bluetooth-mouse could be used at a further distance from a monitor, and while moving about in the room. A Bluetooth-keyboard could be used further away from the monitor. This would reduce eye-strain for persons who are long-sighted. Increasing the distance would also reduce exposure to electromagnetic radiation from the monitor. A Bluetooth-keyboard could also be used to address more than one computer, in a dynamic, switchless manner. You can use your e-mail while your laptop lies in a briefcase; when your laptop receives an E-mail your mobile phone will immediately alert you and then, you can read the received e-mails in your mobile phones display. A businessman may enable his laptop to find a suitable printer once he enters a company.As soon as a suitable printer is found, data will be sent from the laptop to that printer via Bluetooth connection to print it out. Make a connection to printers and faxes without messy cables. Wireless connection to video projectors and digital cameras. An easy and elegance connection from cell phone to handsfree headset. A useful connection between Bluetooth interface to office private branch exchange (PBX). Smooth creating of dial up networks and automatic e-mail. Use mobile phones as office wireless phones. Use of personal computers or PDAs (Personal Digital Assistants) as hands-free phone. Automatic transferring and swapping of files, software, electronic business cards, calendars etc. Dancing couples at a dance hall could receive the music through their headsets and pick the dance of their choice Not to mention many more to come. 3.3The influence of the Bluetooth technology on Society: Thanks to the Bluetooth technology, a wireless LAN (Local Area Network) can be implemented without wires. This means that all the functions of a conventional fixed LAN are available in a WLAN including file sharing, peripheral sharing, Internet access and many more. 3.3.1 Mobility and low cost: Mobility and cost-saving installation are the main advantages of wireless networks in society. Most of the application scenarios of wireless are related to these two features. Mobility enables users to roam on while being connected to backbone networks. Many jobs require wandering workers. Portable computers are indispensable for people like inventory clerks, healthcare workers, police officers, and emergency-care specialists. Wireless networking provides important cost savings in the areas where cables cannot be easily installed, such as historical buildings and residential houses. In distant sites, branch offices and other situations where on-site networking expertise might not be available or fast networking is needed, computers equipped with wireless LANs can be pre-configured and shipped ready to use. 3.3.2 Circulation of Information: The wireless local area network business has been focused on offices since the industry began. But recently, home networking is seen to be a fast growing market. The personal computer has become a powerful platform for education, entertainment, information access and personal finance applications. At home, with the wide use of PCs and the Internet becoming the main way to access information, the role of the PCs has expanded and will continue to expand especially in the area of education. On the social side, this means that wireless networks is the easy way to access internet, find information and at the same time the users gain more knowledge through browsing the internet. 3.3.3Avoiding wire tangle Bluetooth is also one of the examples of using wireless range other than PDA and etc. The objective of Bluetooth technology is to replace cables and infrared links used to connect unrelated electronic devices with one universal short-range radio link. 3.4 Industrial boom Bluetooth applications reflect the mobile phone industry background of the inventors of some famous phone models for example Nokia, Sony Ericsson, Motorola and many more. There are many useful things that Bluetooth had given to our society. 3.5 Information Interchange In meetings and conferences, users can share information instantly with all participants without any wired connections. 3.6 Convenience: A user can also cordlessly run and control, for instance, a projector, or can connect his headset to his laptop or any wired connection to keep hands free for more important tasks while in the office, home or in the car. When laptop receives an email, the user will get an alert on mobile phone. Users can also browse all incoming emails and read those selected on the mobile phones display. Public Bluetooth wireless access points could enable free or charged access to information and services through laptop computers and PDAs. For example, imagine being able to browse the catalog of a public library on your handheld PC as soon as you enter the building. Or, imagine how helpful it would be to have instant PDA access to a building map and to customized real-time flight arrival and departure data as you make your way through a busy airport. Consider the convenience of having automatic, wireless access to a shared hotel printer as you make last-minute changes to a presentation in your hote l room. 3.7 Productive and Time saver: In a Bluetooth-enabled business world, the cellular phone could provide a link to everything beyond the 10-meter range limitation. Without even removing their Bluetooth-enabled cell phone from their briefcase or luggage, mobile professionals would be able to check voice mail, send a fax, receive email, verify inventory levels, and surf the Internet through their laptop computers. This would extend the concept of anytime, anywhere data access well beyond the current standard of cell phones and beepers. 3.8More Freedom: In considering the above scenarios, some may argue that the access of Wireless LAN would increase our freedoms and improve our professional lives because it allowing us to decide when and where we do our work. Wireless certainly has the potential to improve society, and our personal and professional lives in various ways. It gave us many advantages. 4.0 Negative Impact: The convenience of Bluetooth technology cannot be denied, but neither can the way they have negatively impacted daily living. Some of the effects can be dispensed with if boundaries are set. Here we will discuss some negative impact of Bluetooth. 4.1 Violation of Privacy: Mobile phones and PCs usually contain private stuff such as family pictures, bank account numbers, passwords and so on. Unfortunately, these devices are able to be hacked by Bluetooth. The hacker sends a user a file (lets say an image), when received, it will be opened as a usual image where actually it has a built in hacking software. Once the user opens the image, the hacker will be able to control the users device. 4.2 Sabotage: In the same way as downloading from the internet, transferring data via Bluetooth may harm your device if the data contain viruses. The strength of the viruses varies from one to another; some viruses are easy to be removed while some viruses totally damage the device once they reach the device. 4.3 Health Damage: While the topic remains controversial, there are people who believe the microwave radiation the phones emit can cause such problems as cancer and Alzheimers disease from prolonged use. 4.4 Use in inappropriate places: Using Bluetooth to transfer data in inappropriate places is considered to be harmful and such behavior expresses a negative attitude. E.g. Students in a classroom may get busy transferring data via Bluetooth using their hand phones while their lecturer is giving a lecture. 4.5 Sleazy Contents: A child or a teen-ager may innocently receive a file that contains sexual or immoral contents which are not suitable for their age. 5.0 Conclusion and Recommendation: This project was done to assess the impact of Bluetooth technology on the society in the near future. We have investigated in how and why Bluetooth technology has widely spread and what impact that Bluetooth technology has been giving. In addition, we have explained in details the reasons of this impact. Mainly, the bases we had for this report are from a survey that we have done on 100 students and lecturers from the whole population of Multimedia University and Limkokwing University, Cyberjaya campuses. We used the collected data from this survey to explore the impact of Bluetooth technology on the society as we used MMU and Limkokwing Universities as small societies. We have heavily used the internet to collect information about Bluetooth technology and also to find out its impact on other societies. Why our survey was on only 100 people is that, making a survey on a bigger number of people would be expensive and time consuming. This report might be useful to social specialists to find out why some technologies have more interest on people, Bluetooth developers as they can decrease the negative impact of this technology, and to other people who are interested in the relationship between the technology and the society. Future researchers who are going to do a research on the same topic should keep this in mind, this research has been done based on a questionnaire that was made on people who have almost the same range of age as most of them are university students. Future researchers who have a wider research ranges can make their research on different age ranges. The results of the survey showed that 90 % of the people, who have answered the survey, have Bluetooth-enabled devices. The reason of this huge number of Bluetooth users is that, most of the new electronic devices that are available nowadays have Bluetooth technology. Moreover, about 25 % of the participants, who have Bluetooth-enabled devices, have faced negative impact of Bluetooth technology such as getting hacked or received viruses during data transfer. The reason is that most of them didnt know that Bluetooth may carry viruses or hacking software when data is transferred. Even though Bluetooth technology is widely spread so far, we think it will make life easier and more effective if it is spread on a wider range. For example, providing Bluetooth connection in universities laboratories would make data transferring between researchers, students or lecturers easier. However, care must be taken when using data transfers via Bluetooth since data may have viruses or hacking software. A good solution is to use anti-virus and anti-hacker software. Moreover, children and teenagers have to be watched when using Bluetooth-enabled devices.

How Do The Attitudes To Love E :: essays research papers

How Do The Attitudes To Love Expressed In The Following Poems Differ From One Another? The following three poems “To His Coy Mistress';, by Marvell, “The Good Morrow';, by Donne, and “Sonnet 116';, by Shakespeare all tackle the theme of love. Although they are all written about the same subject, they show remarkably different approaches. Two are written from the narrator to his lover to persuade her into commitment into a sexual or loving relationship. The third gives a neutral definition of true love.   Ã‚  Ã‚  Ã‚  Ã‚  Marvell’s is concerned with seizing the moment and living life to the full, and satisfying his need for sexual intercourse in his relationship. The narrator is more concerned about lust than love.   Ã‚  Ã‚  Ã‚  Ã‚  Donne’s point of view comes after sex and he discusses the love between him and his lover and puts lust in his past.   Ã‚  Ã‚  Ã‚  Ã‚  Shakespeare’s “Sonnet 116'; is slightly different as it provides the reader with a definition of ideal and ‘true’ love which gives the effect of a conclusion to Donne’s and Marvell’s poems.   Ã‚  Ã‚  Ã‚  Ã‚  In “To His Coy Mistress';, the speaker, created by Marvell, is trying to get his girlfriend into bed by saying that if they had all the time in the world they could spend a lot of time together and he would really take his time over her, worshipping her as if she were sacred:   Ã‚  Ã‚  Ã‚  Ã‚   “An hundred years should go to praise thine eyes, and on thy forehead gaze. Two hundred to adore each Breast: but thirty thousand to the rest.'; Marvell clearly exaggerates the time into years, which adds to the full effect of this idea of her being worshipped upon and praised almost like a God or a priceless work of art. At the beginning of the first section, the narrator tries to flatter her by saying: “Thou by the Indian Ganges side should’st Rubies find:   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   I by the Tide of Humber would complain.'; Picturing her by the Indian Ganges looking for Rubies makes her sound oriental and possessing exotic beauty. He makes it sound as if he is not worthy of her exotic beauties, he being a complaining commoner. In the second section, it is stated that the couple in fact, does not have all the time in the world: “But at my back I always hear   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Times winged chariot hurrying near.'; This gives the reader a dramatic image of a graceful, winged chariot coming out of the sky where clouds have partitioned to allow it through. “Thy beauty shall no more be found;

Legacy and Respect: The Usefulness of Feminism Essay -- Gender Sexuali

Legacy and Respect: The Usefulness of Feminism In a letter to students who participate in Bryn Mawr and Haverford Colleges' bi-college Feminist and Gender Studies department, Head of the Department Anne Dalke outlined an argument in favor of changing the program's name. She wrote, "Our argument for re-naming the F&GS program "Gender and Sexuality" is based on 3 claims: 1. that it will be enticing for prospective and current students and faculty, because it names their personal and intellectual interests and investments (while avoiding the word "feminism," which is off-putting to a large range of individuals) 2. that it accurately represents the current state of scholarship in the field 3. that it accurately names--and invites exploration of--where the interesting questions lie." At the date in which this statement was composed last April, I probably would have agreed with its relevancy and reasoning. I no longer accept this line of thinking, however, due to my education and involvement in Anne's co-taught class I am taking this semester, Interdisciplinary Perspectives on Gender. It is ironic that I began my study of gender four years ago as a freshman vehemently against feminism, and only now as a senior taking the only class required for every major or concentrator in that field have I come to appreciate the legacy and usefulness of feminism as a theory of practice and of education. My original concepts of feminism were that it was a theory that denounced men and elevated women beyond a fair or equitable place in society. I recognize now the stereotyping that I inadvertently allowed myself to feel.

Feminism Essay -- essays research papers

Both Virginia Woolf, in a speech addressing a graduating all women class, and Naomi Wolf, in her text The Beauty Myth, contemplate feminism from an economic viewpoint. While Woolf believes women need money and a room of their own to have economic independence, Wolf gives credence to the fact that the beauty industry is hindering the independence of women. Through male pomposity, the conventional lives of women, obsession with physical appearance, and the reality that beauty is diverse, both Woolf and Wolf explain the significance of our world's economy. Women have always been economically dependent on men. Any land or money that was in a woman's possession was given to her father or husband. Women have stayed at home working as housewives, cleaning house, and taking care of children. Of course, there have been women who have worked outside of the house, but Woolf sees that kind of work as enslavement. Not much money was made, and not many occupations were open to women. ". what still remains with me. was the poison of fear and bitterness which those days bred in me. To begin with, always to be doing work that one did not wish to do, and to do it like a slave," (Woolf 348). Therefore Woolf concludes that women need to be independent from men, and in order to do so women need to have money of their own. This statement is without a doubt biased, as Woolf is limiting her thesis to those women who have an income without working. Consequently, working women can never really be liberated. One may ask why women have been the poor ones. Why have women been dependent on men, and not men on women? Why haven't women been able to thrive and prosper like men have? The answer lies in the fact that men blow themselves out of proportion. Woolf's theory is that women have been seen as mirrors. "Women have served all these centuries as looking glasses possessing the magic and delicious power of reflecting the figure of man at twice its natural size," (Woolf 346). Because men see women as inferior, men feel superior. If a woman were to stand up for herself and lessen the power of the looking glass, men wouldn't have the feeling of predominance that they occupy now. "The looking-glass vision is of supreme importance because it charges the vitality; it stimulates the nervous system. Take it away and man may die," (Woo... ...s I was writing this paper, an ad for a "Jenny Jones Weight Loss" program came on. Lose nineteen pounds for nineteen dollars, Jenny Jones promises. And a couple days ago heavier people were protesting an ad 24-hour Fitness had exhibited, "When the aliens come, they will eat the fat ones first." Even my nine-year-old sister wonder why her stomach sticks out, she wonders what she can do to be thinner. It's affecting the younger generation. On the other hand, I look at my mother who is successful. She is a single mother who works in a predominantly male occupation, raising three children on her own. In some ways women have progressed, in some ways women have digressed. As women, we need to crack the mirror Virginia Woolf indicated as apparent in our domain. We need to set Shakespeare's sister free, and make the choice to have money and a room of our own. And as Naomi Wolf presented, we need to look for diversity in beauty. We need to become aware of the decrease in self-confidence that is happening in women, and do something about it. While it certainly is not going to happen today, or even tomorrow, on behalf of all women, I hope it happens soon.

Organizational Behavior Trends Essay

Organizational Behavior is the study of what people think, feel, and do in and around organizations. Organizational Culture is the basic pattern of common assumptions, values, and beliefs leading the way employees within an organization think about and act on problems and opportunities. Organizational Trends are patterns of change over time in some variable of interest. In this paper we will evaluate two trends in organizational behavior. The influence of ethics on decision-making and the impact of technology on work-related stress will be examined. Organizational Behavior Trends There are several trends in Organizational Behavior. One trend is globalization, which requires corporate decision makers to be more sensitive to cultural differences as they venture towards a wider variety of employees and clients. Another trend in organizations is the increasingly diverse workforce. Diversity potentially improves decision-making, team performance, and customer service, but it also presents new challenges for the company. The values and ethics of the employees, enable organizations to apply certain principles in a global environment, and are under pressure to abide by the ethical values and higher standards of corporate social responsibility. Ethics on Decision-making Ethics on decision-making is difficult, it is critical for leaders to develop a code of ethics and establish disciplinary actions and procedures for ethical violators. Most importantly, leaders should also develop a process in which employees are rewarded and publicly recognized for having positive ethical behaviors. It is also important to have employee involvement when trying to identify ethical issues. â€Å"When it comes to the ethics of decision making, the criteria individuals use to define problems and the values that underlie these criteria must be considered. Moral conduct is involved in choosing problems, deciding who should be involved, estimating the impacts of alternatives, and selecting an alternative for implementation. Moral conduct does not arise from after-the-fact embarrassment†. (Schermerhorn, Hunt and Osborn, 2005). Overall, ethical decision making, is learning about ethical dilemmas in business and examining the process for identifying common influences in the decision-making process. Once the trends are found, leaders and subordinates must demonstrate and understand how to make an ethical decision in which all possible solutions are attempted equally and without any judgment. Impact of Technology on Work-Related Stress â€Å"Work-related stress can be defined as a pattern of emotional, cognitive, behavioral and physiological reactions to adverse and noxious aspects of work content, work organization and work environment. It is a state characterized by high levels of arousal and distress and often by feelings of not coping. † (www. eiro. eurofound) Work-related stress is a serious issue at many companies. People should be aware of their stress levels and communicate stressful situations to their employer before stress develops into a problem. For this to happen, employers need to ensure that the organizational culture is one in which employees can openly and comfortably talk about work-related stress without any repercussion. There are many components that make up stress. With the world of technology racing news and information around the world as quick as we can blink, many more organizations are becoming sophisticated in applying information technologies. Nobel Laureate and decision scientist Herbert Simon is convinced that computers will someday be more intelligent than humans†. Schermerhorn, Hunt and Osborn, 2005) How does that make you feel knowing that one-day a computer could replace your job? There are always two sides to any debate; the one on stress is no exception. Is being stressed a sign of weakness within your job indicating that you can no longer handle it or is being stressed a sign of an effective working behavior of getting the job done? There are many employers that want to support their staff to the highest level that can be offered but resources and effective training is sometimes limited. As a result, many employees are â€Å"stressed†. The use of technology is needed in all businesses and with this advanced technology some organizations rely heavily it. I know that with the computer system we have at our organization it makes it much easier and less stressful for us. Maybe someone who is not proficient with computers would become stressful to the new system, but for the most part I think technology has a positive impact on work-related stress. Conclusion In conclusion, the influence of ethics on decision-making and the impact of technologies on work-related stress are only two components of many in organizational behavior. With so many changes to how one must work and the many difficult decisions that have to be made according to your organizations ethics only. I personally think that as companies evolve, the employees must chose to either evolve with it or take another course of action to make life stress-free.
