Analysis of data handling Essay Example for Free

Analysis of data handling Essay To get an improved understanding of the problems faced in an online retail data handling system I am going to conduct a questionnaire and gain data from some data capture forms. After gaining information from my questionnaire and data capture forms I now have a clear understanding of how a data handling system is implemented for an online retail store. I now know what information will be kept and which will only be temporary. The products and the customer information will be kept permanently. The customer information is kept permanent but can be changed at any point i. e. a change of address, phone no. etc. When purchases are made little data is added to that which is already stored. The invoice brings together customer information and pairs it with product information. The information added to the invoice would be date of purchase; this information would then automatically create an expected date of arrival and the delivery process, transport, dispatch etc. When customer information is gained it is not input by a member of staff. The information is fed automatically from the websites data capture form which is filled out by the customer. The only information input by staff is the stock information as prices calculation delivery date etc is done automatically by the system. They had a WAN, wide area network. Each of the computer terminals could access the same data so that invoices and other information can be viewed at the same time on different computers. They were also able to check credit card details with banks through their WAN. The data system can produce information for both staff and online customers. Customers can view their past orders or there current account details whilst all data can be viewed by staff. They use standard input devices, keyboard and mouse, as there is no need for particular input devices, for example bar code reader, scanner.

Ethernet system Essay Robert Metcalfe with his colleagues at the Xerox Palo Alto research Center (PARC) developed the experimental Ethernet system. According to O’Reilly and associates (2000) the main purpose of developing the Ethernet system is to interconnect a personal workstation with graphical user interface called Xerox Alto. The experimental system was used in order to connect Altos and also printers and servers. The systems interface‘s signal clock was patterned in the Alto’s system clock. This resulted to 2. 94 Mbps. data transmission rate on the experimental Ethernet. Ethernet was originally known as Alto Aloha Network. Alto Aloha Network was changed its name to Ethernet by Metcalfe to indicate that the system not only support Alto’s but also other computers. And Metcalfe also point out that the Ethernet has progressed way beyond the Aloha system. He chose the name ether as to describe the essential feature of the system which is the physical medium carries bits to all stations the same way as the aluminiferous ether was once believe to proliferate There are two ways which can be used to allocate the capacity of transmission media: baseband and broadband transmissions. Baseband transmission allocates the entire capacity of the medium to one communication channel. It uses distinct values by measuring the voltage in wire which only carried one signal at a time. In broadband transmission, the system allows two or more communication channels to share the bandwidth of the communication medium. The system uses the technique of dividing the bandwidth into frequency bands which is called frequency division multiplexing (FDM) which works only with analog signals. There is also another technique called time-division multiplexing (TDM) that supports digital signals. Figure 1, show the difference between baseband and broadband transmission mode of operation: Figure 1. Difference in the mode of operation between baseband and broadband Broadband transmission is used in the web hosting companies. This is because of the higher speeds of the broadband. With the use of broadband, people can enjoy the full range of internet services like downloading videos, music, watching movies and plying online games. Transceivers have different speeds which are measured in MHz and also specified in wavelengths. The larger the value of the fiber core of the transceivers, measured in microns, there will be more bandwidth possible but also the distance will be shorter. The 1000 Base-LX is the long wavelength with a signaling speed of 1. 25 ±100 ppm GBd. This transceiver can use both 62. 5 and 50 micron multimode fiber and it also uses single-mode fiber optic cables with distances of 440m, 550m and 5 km. Another transreceiver is the 100 Base-TX which uses 4B5B binary encoding to encode 100 Mbps data stream in a signal of 125 MHz. One pair is used for transmitting data while the other pair is used for receiving the data. Given this, one user can setup a system for full duplex communication given that there are only interfaces in the same collision domain. It is either the two computers are directly connected to each other by crossover cable or a computer directly connected to a switch. Full duplex communication result to doubling the potential throughput but not often reached more than the modest improvement. Based on Sheldon and Big Sur Multimedia (2001), link aggregation is the process of connecting together two or more data channels in order to become a single channel which appears as a single, higher-bandwidth logical link. Also this aggregated links can provide redundancy and fault tolerance if the links follow different physical path. By linking the digital lines, the link aggregation improves the access to public networks. The aggregation is also use in enterprise network to build multigigabit backbone links. It also allows the network’s backbone speed to grow increasingly when the demands on the network increases without replacing everything and buy new and expensive hardware. Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) protocol was intended for local area network (LAN) environments where in all the nodes are positioned few hundred feet from each other. The importance of the protocol is to listen up each node to the channels in a short period of time before it transmits. The main assumption of the protocol is that each node should be able to hear the transmission from every other station. But this assumption is violated in access network and this resulted to several problems. One of the serious problems encountered is the hidden transmitter problem. This occurs when the CSMA/CA cannot function properly due to a wireless node cannot hear one or more of the other nodes. And when this happen, multiple nodes attempt to transmit their data simultaneously over the shared data thus resulting to interference with each other. To address the hidden transmitter problem, the 802. 11 standard uses the protocol request to send/clear to send (RTS/CTS). Before transmitting each packet, each node transmit an RTS packet to other nodes to warn them that it is about to transmit data and after each transmission, it broadcasts CTS packet. This process is time and bandwidth consuming process and it is required for each and every transmission by each and every wireless node. But this process sill does not address the hidden transmitter problem fully because RTS/CTS packets are subjected to repeated collisions. In most applications, the wireless standard 802. 11b operating at 2. 4 ghz is ample enough. This wireless standard is the mostly widely accepted standard among the three wireless standards and also the price of the equipment is the cheapest because of the rising demand for the 802. 11g. Its distance will rely mostly on the communicating devices whether it have line of site or not. And with fewer obstacles among the transmitting and receiving devices, there will be better wireless connection and therefore much better web surfing. The 802. 11b wireless standard is good enough if using wireless route or access point only for internet usage because the connection to internet via broadband modem operates about 2mbps which is very fast. The 802. 11b transfer data at the rate of 11mbps which is sufficient for internet usage. This device saves money on equipment and gives great web surfing services. Another wireless standard being used is the 802. 11g standard. It is replacing the widely accepted standard which is the 802. 11b because both operate on the same frequency and the price drastically goes down on products. This standard is much very similar to 802. 11b because it also usually needs a line of site to achieve optical performance. Both standards, 802. 11b and 802. 11g operate at the same frequency range of 2. 4ghz and are inter-operable with each other. All the devices of 802. 11g can communicate with 802. 11 devices and the main advantage of the 802. 11g devices is that when transferring files betweens computers or networks, it is usually at a greater speed. It is recommended to use 802. 11g when using wireless connection to transfer files (data files, voice, music, and videos) around the home and office. 802. 11g standard also allows manufacturers to developed devices which work at speed of up to 108mbps because it recommended when transferring large data or audio files within LAN. Wi-Fi Protected Access (WPA) is a security technology that is used in wireless network. This was created by an industry trade group called the Wi-Fi Alliance which owns the trademark for the name Wi-Fi and certifies products that bear the name. WPA was created in order to response on the serious weaknesses of the previous system, the Wired Equivalent Privacy (WEP) and also to improve the authentication and encryption features of the WEP. It implements majority of the IEEE 802. 11i and intended to take place the place of WEP. It was designed in order to work with all wireless network interface cards but not with first generation wireless access point. Temporal Key Integrity Protocol (TKIP) is one of the key technologies behind WPA which deals with the encryption weaknesses of the WEP. Also the WAP have built-in authentication which is a key component. The WAP uses the RC4 stream cipher which has a 128-bit key and a 49-bit initialization vector (IV). With the combination of the TKIP and the RC4 stream cipher; this solves the problem of key recovery attacks which was found in WEP. In addition, the WPA provides much improved payload integrity. WPA uses a more secured message authentication code (MAC) but also termed as MIC which stand for message integrity code which is an algorithm â€Å"Michael†. MIC includes a frame counter preventing replay attacks. With the features of the WPA like having increased size of the keys and IV’s, reduced number of packets sent with related keys and adding up of a secured message verification system, it is far more difficult to break in within the system. There is one variation in WPA which is called the WPA pre shared key (WPA-PSK), which is also known as personal mode. This was designed for home and small office usage and networks which can’t afford the cost and complexity of the 802. 1X authentication server. To access the network, the user must enter a pass phrase, with 8 to 63 printable ASCII characters or 64 hexadecimal digits. This can be stored in the user’s computer with discretion under most operating system in order to avoid re-entry and must remain in the Wi-Fi access point. Protected Extensible Authentication Protocol (PEAP) securely transmits authentication information which includes password, over wired and wireless network. It is also an 802. 1x authentication type for wireless LAN’s. The PEAP is created by the Cisco Systems, Microsoft and RSA Security which is base on the Internet Draft submitted to the IETF. (Cisco Systems, 2007) The system uses only server side public key certificates which authenticate clients by creating encrypted SSL/TLS tunnel in between client and authentic server. This protects from casual inspection the resulting exchange of authentication. According to the Cisco Systems Inc. , the following are important benefits of the PEAP web security system: †¢ It relies on the Transport Layer Security (TLS) which allow non-encrypted authentication types (EAP-Generic Token Card and One Time Password (OTP)) support †¢ It uses the server-side Public-Key Infrastructure (PKI) based digital certification authentication †¢ It allows for the authentication to an extended suite of directories which include Lightweight Directory Access Protocol (LDAP), Novell NDS and OTPA databases †¢ It uses the TLS in order to encrypt all the user-sensitive authentication information †¢ It supports the password change at expiration †¢ It does not display the logon username in the EAP identity response †¢ The system is not susceptible to dictionary attacks †¢ It offer dynamic privacy protection while using in combination with Temporal Key Integrity Protocol (TKIP) or the Advanced Encryption Standard (AES) Also the PEAP have enterprise benefit. Based on the Cisco System Inc. , PEAP is based upon the server-side EAP-TLS. This means that organization can avoid the issue associated in the installing of digital certificates on every client machine which is required by the EAP-TLS. This provides the enterprise to choose what method of client authentication depending on their needs. PEAP authentication work in two phases: ? In phase 1, performing the server-side TLS authentication will result to creation of an encrypted tunnel and will achieve server-side authentication. One the process is done the data are encrypted with all the user-sensitive information ? For phase 2 according to the Cisco System Inc. , the client is authenticated by using methods like the EAP-GTC and the Microsoft Challenge Authentication Protocol (MS-CHAP) Public switched telephone network (PSTN) is referred as the public communication providing local, extended and long distance call telephone service. It is composed of telephone exchanges arranged in order to have nationwide telephone communication system. The system is open for those who can afford the service. Packets, pieces of the caller’s conversation are switched and then sent simultaneously to many connections to reach a receiver in the other end. All the phones in PSTN are connected in a way that any phone can call to any other phone due to all the local phone systems are connected to each other. Mitchell (2007) cited that PSTN provides the traditional Plain Old Telephone Service (POTS) to establishments and residences and also some parts of the PSTN are being utilized for DSL, VoIP and other internet-based network. In much relation to internet, this provides much of the internet’s long-distance infrastructure. Internet service providers (ISP) pay the long distance provider for the access to their infrastructure and they share the circuits among users in the process called packet switching. PSTN network link supports 64 kbps and in residences the PSTN phone lines carrying the bandwidth is made up of copper cable. Dial-up modems utilize 56kbps of the bandwidth when they are connected to a phone line. Also the PSTN utilizes the SS7 signaling protocol. SS7 signaling protocol support the exchange of special-purpose messages on public telephone networks. SS7 messages pass over separate channel different from the channel used for voice communication and it is referred as out of band signaling. Wireless local loop is sometimes called radio in the loop (RITL) or fixed –radio access (FRA). It is a system that connects users and subscribers to the public switched telephone network (PSTN) by the use of radio signals as substitute for copper for all part of the connection between subscriber and the switch. This includes cordless access systems; propriety fixed radio access and fixed cellular systems. One of the advantages of the wireless local loop is that it can be deployed in just weeks or months in comparison with copper wire systems which took months and years for the deployments. The instillation of the wireless local loop considerately has much lower construction cost than laying copper lines. The maintenance and operations of the wireless local loop are that easy and the average maintenance time per subscriber is shorter by 3 to 4 times. Signaling is the exchange between information which concerns about the establishment and in the control of a connection and the management of the network. There are many types of signaling: †¢ In-band signaling pertains to the exchange of signaling information within the same channel of the telephone call †¢ Out-of-band signaling is telecommunication signaling meaning exchange of information to control telephone call. It is done over a channel and it separates from channels which is use for telephone call. This signaling is used by Signaling system #7, the signaling standard controlling the world’s phone calls †¢ Line signaling is much concerned in transmitting information on the state of line or channel †¢ Register signaling is focused on the transmittance of information in the calling/ called telephone number †¢ Channels-associated signaling utilizes signaling channels dedicating to a specific bearer channel †¢ Common-channels signaling, utilizes signaling channels which transmit signaling information to multiple bearer channels. †¢ Compelled signaling pertains to the need of the receive signal to be fully acknowledged before the next signal is sent. †¢ Subscriber signaling pertains to the telephone and the telephone exchanges †¢ Trunk signaling pertains to the exchange.

Why did jammu and kashmir conflict start

Why did jammu and kashmir conflict start Since 1989 Jammu and Kashmir has been the most important issue in the Indias internal security scenario. Jammu and Kashmir was a major site of the extremely bloody 1947 war. The first few years saw a relative domination by terrorist group when the casualties were mainly civilians. Jammu and Kashmir which lies in the northwest of the subcontinent bordering china. At the time of partition -the British provinces divide two countries India and Pakistan the Hindu majority on the side of India and the Muslim majority on the side of Pakistan and j s k one such a rich pricey and nature rich state had a vesicular problem. Because its the state is in India at the time of partition means under Hindu majority but having Muslim population. In 1947 the population of Kashmir is 77% of Muslims and 20 % of Hindu. After the partition both the country claims that J and k is theirs country state but the result they had wars with each others many times over this region. In 1987 the alliance won and Faroo q Abdullah was the chief minister of the Kashmir. The relation between India and Pakistan is soured. They fought three times in 1947 to 1948, in 1965 and in 1971.so in this quarrel then United Nations invited. From the Indian side it instead that the no referendum could occur until all of the state had been cleared of irregulars. The Jammu and Kashmir are has been administrated by both India and Pakistan .The insurgency was first predominant in Srinagar when militants were largely Kashmirs youth. Muslims are majority in poonch, rajouri, kisth, and doda. And the Shia Muslims make for majority in kargil region. The definition of insurgency means is an armed rebellion against a authority (for ex- which recognised by the United Nations) those who taking part in this rebellion are not recognised by any nation. Insurgency in Jammu and Kashmir existed in various forms. It includes, civilians, Kashmir are, Indian armed forced and foreign militants etc. Kashmir has been the target by all the sides in the conflict. After the elections of 1987 some of the state legislative assembly formed groups or militant wings and further more that has started a catalyst for the insurgency. And it was the starting point of the insurgency in j and k .According the press release there were 3,400 cases of disappearances. U.S intelligences also believes that the al-Qaeda and Taliban are helping to organizing terror camps in Kashmir to foment conflicts it has left more than 4.7000 people dead till 2009.and in the year of 2000 because of insurgencies 31,000 Indian civilians lost their lives .terror camps play a central role in this Insurgencies. The Pakistans inter services intelligence has been accused by India many times to supporting and training terrorists. Like between India and Pakistan. The government believes that the terrorists groups from Afghanistan entered in to this region with the help of isi (Pakistans intelligence).since then the violence has increased significantly in stre ngth. Some parties which are present in the j and k are demanding for an independent Kashmir these parties names are hurriyat conference and Jammu and Kashmir liberation front. Other militant groups favour as a Pakistani Kashmir. It is hard to determine the total numbers of casualties. Because in Jammu and Kashmir it is very common after the partition. Kashmir continuous to remain at the highest volatile region in the world with a highest average of 2,500 every year. Every individual has his or her own ideology so some fight in the name of the religion and some are for independent Kashmir. Several new groups and organisation have also emerged. India claims that the there are also other afghan, Egyptian and Bangladeshi terror active in Jammu and Kashmir. And Is I is the main suppliers of funds and support these groups. But the Pakistani government always denied these type of statements to India. Richer Bennett, a British intelligence analyst that the isi helped these militant groups and has many of their attacks both within the Kashmir and the other major big cities of India. There are between 2,600 to 3,600 militant camps across Pakistan and Pakistan administrated Kashmir. The FBI has also produced images of camps which are located in pok. India claims that the every year thousand of armed and terrorists cross the loc and enter into the Indias administrated Kashmir and spread the terror. During a piece summit between Pakistans former president pervej Mushrraf and Indias former president Atal Bihari Vajpayee in Jan 2004.pakistan assured that they would do everything possible to curb the activities any training camps on its territory. But the violence has continued despite three year long peace process between India and Pakistan. In 2005 there were 166 incidents in the result 201 people are died. So all the problem faced by both the country people. Islamabad has done little to stop the training camps on its soil it was the statement by p. mussaraf the former pri me minister of Pakistan the statement was a truly fake or false statement. Covered by the media. However India claims that the Islamabad supports these terror groups. Thousand of pandits move from Kashmir because of terror. Not much about these groups some says that they collaborate and they are the members of an alliance known as united jihad council. the two groups which India says they were behind the attack in parliament in New Delhi .they are known as jaish -e-Mohammed and lashkar -e- toiba. They are in the favour of Pakistans Kashmir. They are believed to be the members of u g c. In a letter to American people written by Osama bin laden he stated the reasons that why he was fighting against America is because of her support to India on the Kashmir issue. The u .s secretary of defence on a trip to New Delhi in 2002 suggested that al-Qaeda was active in Kashmir. India says that the it was jaish e Mohammed who hijacked the Indian airline flight I c 814 to Kandahar and to force th e Indian government to release the commander of Jaish e Mohammed named Maulana Masood azhar and also attacked the assembly of Kashmir in 2001. All the support or you can say the arms given to them by Pakistan military or i s i. Between august 1988 and at the end of 1989 JKLF was the only terrorist group present in insurgency in Jammu and Kashmir. Later the I s I promot them. The main work of I s I is to give arms to the militants and help them to shifted them to Indians administrated Kashmir. Because of terrorism the state, tourism has been badly affected. Insurgency is the most threatening attempt by Pakistan. It has used to seize the state. Pakistan knows that it this phase of insurgency does not flair up into an open war. The situation came closer in june1999 in the Kargil region when Pakistans army regulars were detected holding positions in peaks of loc. India frequently warned many a times to Pakistan that finish that terrorists camps but Pakistan government always indulged th e statements that their country is peaceful and no terror activities involved by their country. Some of Pakistans Organistaions report that Indian armed forces have been responsible for the death of 4,500 Kashmiri. So Pakistan have also point out India many time In the year of 1990 to 1999 there are 4,242 cases of rape of womens in Kashmir. Another reason of dispute over Kashmir is water. Jehlum and Chenab which flows in Pakistan and the three river ravi , Sutlej and beas irrigate in northern India. In 1960 the Indus water treaty signed to resolved the most of dispute over the sharing of water. But the Pakistan raised the issue when India constructed the dams on its side and which limit water to Pakistans side. How to control the insurgency in Jammu and Kashmir? There is a possibility of changing everything for the good. Religious terrorism is a major part of today. Both the countries should take steps for remove the terrorists parties from their country specially for Pakistan. Pakistan needs to destroys all the camps of terrorists. Because it is the time to finish the issue not to make the issue. So, it is our responsibility to stop the terrorist attacks and to fight with terrorists. .We had already soft on the terror. There are only four or five countries which fight like a child war for states. We have done nothing except kill our men and people of the other countries. Both the countries India and Pakistan have same religions , currency and etc so we are the two faces of one coin. Respect the other religions. I DREAM THAT THE INDIA WE LEAVE BEHIND WILL BE MUCH MORE WONDERFUL THAN THE INDIA WE INHERITED. I SINCERELY HOPE YOU SHARE MY DREAM.THANK YOU

Bio Technology :: essays research papers

Tinkering With Mother Nature Imagine thirty or forty years form now. Biotechnology has really advanced. Scientist can now clone people and also change their DNA strands making them better or perfect all around. Do you think that it is safe to tinker with Mother Nature? Is it wise to try and control Mother Nature? Better yet can she ever be controlled? Whether or not she can be controlled is a big of deal. If we can control Mother Nature she will end up controlling us sooner or later. It is not a smart idea to tinker with such a great power that the world has depended on for many years.   Ã‚  Ã‚  Ã‚  Ã‚  Scientist can study and try to do many things but one thing they can never do is control Mother Nature. I believe biotechnology is not really necessary in this day in age. What is the point in trying to clone a person and make them better? This technology can be very harmful to us as well as the earth. Biotechnology will change many things and can ruin the balance of nature. In the short story by Jeremy Rifkin, he states â€Å"Initial fears focused on the nightmare scenario of newly engineered microorganisms escaping from the lab and causing uncontrollable damage to the other organisms in the environment.†(The Ultimate Therapy: Commercial Eugenics on the Eve of the Biotech Century p.542-543) If the balance of nature is interrupted it can cause a lot of destruction. For example if a scientist were to take a species of any type from its original habitat and introduce it to a new environment it will cause the environment to change as well as its balance. The s pecies may eliminate other species causing the food chain to change.   Ã‚  Ã‚  Ã‚  Ã‚  Biotechnology is a great danger to the human species. Imagine people walking around looking like twins but one is better in every way then the other. There is already enough racism in this world why do we need to set new standard of a persons well being in his or her society. If scientist were to clone people they could improve the clone, putting the natural human specie at a lower level of life. There would no longer be natural people all the clones would survive caused by Darwin’s theory â€Å"Survival of the fittest.† These new breeds of human could be programmed from birth to be any thing like ruthless soldier for wars.

Rise of the Superpowers :: Superpowers International Affairs War Essays

Rise of the Superpowers It is often wondered how the superpowers achieved their position of dominance. It seems that the maturing of the two superpowers, Russia and the United States, can be traced to World War II. To be a superpower, a nation needs to have a strong economy, an overpowering military, immense international political power and, related to this, a strong national ideology. It was this war, and its results, that caused each of these superpowers to experience such a preponderance of power. Before the war, both nations were fit to be described as great powers, but it would be erroneous to say that they were superpowers at that point. To understand how the second World War impacted these nations so greatly, we must examine the causes of the war. The United States gained its strength in world affairs from its status as an economic power. In the years before the war, America was the world’s largest producer. In the USSR at the same time, Stalin was implementing his ‘five year plans’ to modernise the Soviet economy. From these situations, similar foreign policies resulted from widely divergent origins. Roosevelt’s isolationism emerged from the wide and prevalent domestic desire to remain neutral in any international conflicts. It commonly widely believed that Americans entered the first World War simply in order to save industry’s capitalist investments in Europe. Whether this is the case or not, Roosevelt was forced to work with an inherently isolationist Congress, only expanding its horizons after the bombing of Pearl Harbour. He signed the Neutrality Act of 1935, making it illegal for the United States to ship arms to the belligerents of any conflict. The act also stated that belligerents could buy only non-armaments from the US, and even these were only to be bought with cash. In contrast, Stalin was by necessity interested in European affairs, but only to the point of concern to the USSR. Russian foreign policy was fundamentally Leninist in its concern to keep the USSR out of war. Stalin wanted to consolidate Communist power and modernise the country's industry. The Soviet Union was committed to collective action for peace, as long as that commitment did not mean that the Soviet Union would take a brunt of a Nazi attack as a result. Examples of this can be seen in the Soviet Unions’ attempts to achieve a mutual assistance treaty with Britain and France. These treaties, however, were designed more to create security for the West, as opposed to keeping all three signatories from harm. At the same time, Stalin was attempting to

Introduction The topic I have chosen to look into for this assignment will be â€Å"When it comes to their health, workers always know best.† (Workers Health International Newsletter No. 42).† Analyse the different research methods that unions and workers use to identify ill health caused by work. I have chosen to look into this subject to see what different research methods are out there and what kind of information we can gather from them. I will do this by analysing and evaluating each known method, and then establishing which is more suitable for my own workplace. I intend to be able to use some of these research methods on my members and in my workplace, to see if there are any potential hazards in the workplace. After trying out some of these research methods I will collate the data and if an issue is raised create a plan of action to eliminate the problem. I also intend to share my findings with my members and present this data at the next health and safety meeting. What types of research method is there? A simple research method would be to â€Å"look and listen† by this I mean observe your surroundings, listen to members concerns, check things like the accident book or has there been a number of claims? Another type of research can be to do comparisons between different things in the workplace for example does one area have more accidents then another or does an area have additional hazards compared to others. A really useful research method for trying to find out if there is a specific health problem with your work is body mapping. Body mapping is a way of identifying common patterns of health problems amongst workers in a particular workplace or doing the same job. Whilst it is not certain that any such common ailments are work-related, it highlights areas for further investigation. A similar technique is risk mapping/hazard mapping where instead of highlighting areas of pain on the body like a body map does this highlights risks on a map of the workplace. From this map you will be able to build up a clear picture of where the hazards lie in the workplace. One of the most popular types of research is to do a survey, this may be because there are lots of different ways you can do surveys and you can tailor them to be as specific as you want. You don’t even have to come up with the questionnaire yourself as there are a lot of pre made ones online which may fulfil your needs. Another research method is to examine records to see if you can find any anomalies or similarities in the data. Records can range from asbestos registers to pesticide passports. Pros and cons of research methods Body mapping One of the pros of body mapping is that it is a simple starting point to be able to identify health problems within the workforce. Another advantage is that it is very easy to set up, and very quick to be able to participate in, even those with disabilities and those who are not English speaking can partake, which should encourage people to take part. The results can be swiftly obtained, and are clear and easy to present to management. A strength of using this method is that it can raise health and safety awareness in the workplace, and then finally body mapping can be anonymous, hopefully encouraging more members to get involved. A weakness of the body mapping method is that it is only a starting point for investigation, and it is hard to pin down to work issues, and so you would need to follow it up with different research methods, for example: surveys and discussions to try and highlight what the hazard may be. A disadvantage is that all employees’ who have taken part would need to do the same job in order for the data to work or you have to do multiple body maps (the hazards may vary from job to job). Surveys One of the advantages of using the survey method is that it can be conveyed in multiple ways, such as email, internet, paper or post. This style of research makes it easy to target large populations of people. Another pro is that the survey can be as specific or general as you like, dependent upon the questions you wish to ask. You can ask open questions which will give you detailed responses, or closed questions which are quick to interpret data from and you will get fast results. By using this method you can repeatedly use the same survey over a period of time to assess any changes that may be taking place. A disadvantage of this method is that survey design often requires special skills from the researcher in sampling proper question design and analysis. Another weakness is open questions can create a lot of data which is time consuming to analyse and it may also put people off participating. Surveys might not be accessible to all members, such as foreign workers or people with disabilities. Another drawback is that it is difficult to get people to participate as it takes too much time to complete or they cannot be bothered. Risk mapping By using the risk mapping method, it can highlight to workers any potential hazards that they may be exposed to, and any physical, chemical or biological problems that might arise when doing the job. Workplace risk mapping is a technique where workers can get together to get these concerns down on paper. This approach takes the control away from experts like health and safety professionals, by using the knowledge of workers and acknowledging the essential contribution they make, and are developed from everyday experiences. Risk maps can be enhanced if the hazards are coded using colours or symbols, it may even be possible to match these codes to areas with body mapping results. An advantage of using this method is that it can allow workers to keep track of management’s activities to remedy the hazards the map has identified. A disadvantage of the risk mapping method is workers may lack interest in the process, and wish to ignore hazards in their work area, especially if they have been doing the job for a long time, not wishing to change from what they have been doing (they may be scared of change). A weakness can be seen to be employers not enforcing the findings of the risk mapping, therefore encouraging members to work unsafely. There could be an issue with members not wanting to take part due to a worry of pressure from management to ‘get the job done’. A weakness could be that if there is a lack of commitment from employers once issues have been highlighted, there could be a delay in the risk being removed or controlled. Conclusion and recommendations After analysing various types of research methods, it is clear that no method is perfect. It seems that depending upon the type of data required, this may determine which method is best to be rolled out. Even the possibility that one research method might not be enough to get all data required (the body mapping method may only be a starting point), and so more than one method may be suitable in certain cases. From analysing this data, when approaching the workforce it may be better to use more than one approach in order to accurately report potential risks to management. This approach will not only make the data more precise, but also make the case more conclusive. After looking into all the different research methods I intend to recommend that either the TU or the company, or both utilise some of the research methods, starting with body mapping and leading on from there to other techniques.
