Metastatic Cancer: Types and Causes

Metastatic Cancer: Types and Causes Introduction Cancer is something that many people face or is affected by in some way. Cancer is a problem that is global and always growing affecting more people as the world’s population increases. The 2012 statistics show that were about 3.45 million new cases of cancer and 1.75 million deaths as a result of cancer worldwide in the year 2012. The main cancer site being breast contributing 464,000 cases [Ferlay, Foucher, Tieulent, Et.al, 2013]. Thanks to a better understanding and better treatment of cancer like chemotherapy and cancer based drugs, there has been a decrease in death from cancer and so better survival rates for both males and females affect by cancer [Jemal, Simard, Dorell, Et.al, 2012]. The fact cancer is so prevalent worldwide is due to the many features and ways that cancer affects people. One of these features is that some cancer cells are not static. The cancer cells are able to alter and change in order to form into another cancer that is in another part of the body therefore affecting a different organ site. This ability for cancer cells to move or migrate to different parts of the body is known as Metastasis [Yachida, Jones, Bozic, Et.al, 2010] [Fokas, Cabillic, Et.al, 2007]. The fact that cancer cells are able to migrate to other sites of the body is not just random. Where the cells migrate to, is dependent on where the cancer cells was originally was before the migration. What dictates where the cancer cells go, are specific stimuli or environment within the body so that the cells are able to grow into tumours. The stimuli or environment may consist of specific receptors or chemokines that are shared or common between the two sites [Baruch, 2009]. When cancer has metastasised to a different area the site that the cancer had originated in is known as the primary cancer and the site at which the cancer cells moved to is known as metastatic cancer. A common type of metastasis is from breast to brain, with breast being the primary cancer and br ain being the metastatic cancer. Breast cancer is often found to metastase to the brain, the chances of this occurring are increased when patients have HER2 over expression [Gupta, Adkins, Et.al, 2013]. HER2 comes from the human epidermal growth factor receptor family that controls response such as cell growth and cell differentiation, therefore it can be easily predicted that over expression of HER2 leads to uncontrollable cell growth a feature that is in all cancers [Rubin Yarden, 2001]. The metastasises of cancer within patients does not affect them straight away, as it often takes years for the metastatic cancer to be detected and to affect the person. When the primary tumour has grown, only then will the tumour cells migrate and invade to another part of the body and grow at the site. When the tumour cells are at the new site then they the process of cell growth occurs at the site. But it has been shown that the tumour cells at the new site have been dormant which accounts for the time between the detection of the primary cancer and the metastatic cancer [Rà ¶cken, 2010]. The way the metastatic cancer cells move from their primary site to their metastatic site can be many ways depending on ultimately were the tumour formation will be formed in. Examples of the movement or migration are 1) local tissue invasion which is movement of the tumour cells through the tissue, 2) hematogenous spread which is the movement through the blood; 3) lymphatic spread which similar to the blood by uses the lymph nodes and finally 4) spreading through surfaces and cavities [Pepper, 2001]. There are many sites of metastatasis, below is a summary table of the sites and where they originated from [Nguyen, Bos, Massaguà ©, 2009]. Table 1: A brief summary list that shows the sites of metastasis from primary tumours [Nguyen, Bos, Massaguà ©, 2009]. A metastatic cancer that is particularly important and of interest is metastatic cancer that is able to migrate to the brain. From the table above it can be seen that sites of metastasis for the brain is only in 3 types of tumours, these being breast, lung adenocarcinoma and skin melanoma. Out of these three types’ lung and breast tumours usually metastases to the brain making up 60% of brain metastasises [Nguyen, DeAngelis, 2004]. The reason why brain metastasis is of particular interest is because of how the metastatic cancer is able to pass through the blood brain barrier (BBB). In order to understand the movement of the blood brain barrier it structure must first be looked at. The blood brain barrier is made up of 4 main sections or parts that are of important to it function. These 4 parts are 1) tight junctions, 2) adherens junctions, 3) astrocytes, and 4) pericytes, each section has its own function as well. The tight junctions are made up of claudin, occludin, and junct ion adhesion molecules these are transmembrane proteins which are involved in cell-to-cell adhesion. Adheren junctions are responsible for paracellular permeability. Astrocytes are for structural supports and also for guiding of neurons and finally the pericytes are for mechanical support for cell attachment. [Lawther, Kumar, Krovvidi, 2011] [Hawkins, OKane, Simpson, Et.al 2006]. Figure 1: Image showing the main parts of the BBB and the overall structure of the BBB. Image was extracted from [Lawther, Kumar, Krovvidi, 2011]. Now that the structure of the blood brain barrier can be seen more clearly, a better understanding of how metastatic brain tumours form and how the cells pass through the blood brain barrier. More specifically primary breast cancer that produces metastatic brain tumour can be looked at. The tumour cells that are being metastasised are able to express vascular endothelial growth factor (VGEF). The expression of the vascular endothelial growth factor by the tumour cells is able to disrupt the blood brain barriers permeability which allows the cells to pass through and into the brain [Gerstner, Fine, 2007]. Another way to metastasise to the brain is by the tumour breast cells attaching or invading the brain microvascular endothelial cells and then passes through the blood brain barrier [Arshad, Wang, Sy. Et.al, 2011]. The survival rates of patients that have a metastatic brain tumour in unfortunately not very high. Those patients that have had primary breast cancer and then later gaine d a metastatic brain tumour have between 30-40% chance of death due to the metastatic brain tumour [Wadasadawala, Gupta, Bagul, 2007] [Jaboin, Ferraro, DeWees, Et.al, 2013]. There are treatments available that help fight against metastatic brain tumours the main one and most effective being radiotherapy. However the effectiveness of radiotherapy is dependent of where the tumour cells had originated from i.e. which primary cancer the patient had first. Those that had primary lung or breast cancer are more sensitive to the radiotherapy treatment. Other types of treatments include Craniotomy, Postoperative radiotherapy, and Stereotactic radiosurgery. The treatment that is craniotomy is not used often as it is stressful for the patients. Postoperative radiotherapy is also an effective treatment that improves the life of the person, however there are side effects or conditions that can occur as well like disorder of the nervous system or dementia. The final treatment stated is Stereotact ic radiosurgery which involves using gamma radiation on the site of the tumour [Shibui, 1999]. With the use of radiation is the fear of persevering the nearby cells and tissues. With the advancement of science and technology the treatment of using radiotherapy has become better. The use of radiotherapy is still the main treatment but with better radiotherapy processes and technique the preservation of the cells and tissue from radiation has greatly improved [Owonikoko, Arbiser, Zelnak, Et.al, 2014]. Epithelial–mesenchymal transition (EMT) Epithelial–mesenchymal transition (EMT) is defined as a biological process that occurs within polarised epithelial cells which interact with the basement membrane. The polarised epithelial cells undergo many biological changes that brings about a mesenchymal cell phenotype, these changes include an increased ability of migration, invasion and develop a resistance to the process of apoptosis [Kalluri Weinberg, 2009]. There are keys differences between the epithelial cells and the mesenchymal cells. Epithelial cells are cells that form layers, which are tightly packed by membrane structure such as tight junctions, gap junctions’ adherens junctions and desosomes. These cells do possess an ability of motility, however under normal condition they remain they do not move. In comparison the mesenchymal cells are not organised into layers like epithelial cells. The main difference between the two is that mesenchymal cells are very motile whereas epithelial are not normally [Th iery Sleeman, 2006].The whole process of epithelial–mesenchymal transition plays a role in normal development. These normal developments include gastrulation which is an early phase in embryonic development and heart morphogenesis which need and take advantage of the transition between the epithelial cells into mesenchymal cells. Another key role of the EMT is that it is for the down regulation of E-cadherin [Larue Bellacosa, 2005]. E-cadherin is a tumour suppressor that is encoded by the Cadherin-1 (CDH1) gene that is key for the suppression of carcinoma progression. It has been found and seen that the loss of the Cadherin-1 at EMT sites are linked to the formation, development of cancer. The reason for this is due to the fact that the loss of the E-cadherin increases the ability of invasion in cells [Wang Shang, 2013]. As with any biological process there are transcription factors that cause and regulate the transition. The transcription factors that mediate the processes are SNAI1 which down regulates E-cadherin, Zinc finger E-box (ZEB) and also basic helix–loop–helix transcription factors [Lamouille, Xu, Derynck, 2014]. There are features and properties of the mesenchymal cells that can be linked to cancer if not regulated properly. The mesenchymal cells are able to produce and secrete chemokines and growth factors that stimulate cell growth and angiogenesis. Another key feature of the mesenchymal cells is that they have anti apoptotic properties that can stop or save cells from undergoing apoptosis [Murphy, Moncivais, Caplan, 2013]. Just from seeing the features of the mesenchymal cells it can easily be seen that if the regulation of the process, mutation or changes in expression occur the consequences can be predicted and linked to the formation of cancer. The final aspect of epit helial–mesenchymal transition is how it is linked to the formation of cancer and more specifically metastatic cancers. As stated epithelial–mesenchymal transition is regulated by many growth factors and proteins such as Epidermal growth factor, Hepatocyte growth factor and Transforming growth factor beta, all of which if changed by mutation or expression can ultimately contribute to the hallmarks of metastatic cancer like uncontrollable cell growth and invasion into other tissues and organs in the body which is the main feature of metastatic cancer [Gos, MiÅ‚oszewska, Przybyszewska, 2009]. Below is a diagram that summarises and shows the process of how epithelial–mesenchymal transition can promote the formation of metastatic cancer [Kongemail, Liemail, Wangemail, Et.al, 2011]. Figure 2: A summary of how epithelial–mesenchymal transition can be linked to metastatic cancer. EMT is the process of epithelial–mesenchymal transition and MET is the process of Mesenchymal–Epithelial Transition. Image taken from [Kongemail, Liemail, Wangemail, Et.al, 2011]. The image above shows the transition of a primary tumour into a metastatic tumour and reason for this to happen. Red arrows show aspects that may be gone wrong due mutation or change in expression through methylation. Epigenetics Epigenetics is the genetic control by using factors that does not include a person’s DNA sequence [Simmons, 2008]. Epigenetic control or regulation is the process whereby genes are activated or deactivated within a cell [Mitsuyoshi Nakao, 2001]. Essentially the concept of epigenetics is the change in gene expression that can be caused by certain mechanisms such as DNA Methylation or Histone modification. These changes in gene expression whereby expression of a gene is switched on or off can be inherited and passed on. The idea of epigenetics and its mechanism is needed for maintenance of genes that are specific to tissues. Changes in the process of epigenetics, like DNA Methylation or Histone modification causes disruptions in a genes function, which alters its expression and is one of the hallmarks of how cancer begins [Sharma, Kelly, Jones, 2010]. As stated there two ways that can causes changes, histone modification and DNA methylation which will be the main focus of this p aper. The process of histone modification to a certan extent is reversible depending on the type of modification. The process of DNA methylation is more long term creating long-term repression [Cedar Bergman, 2009]. DNA methylation is the common mechanism in which genes are activated or deactivated by the addition of a methyl group to cytosine or adenine bases, making it an epigenetic signal tool. Changes in the process of DNA methylation can result in a gene being constantly activated or deactivated which can lead to brain tumours or other tumours in the body [Phillips, 2008]. The process of DNA methylation is catalysed by the family of enzymes known as DNA methyltransferases. DNA methyltransferases is an important enzyme in epigenetic silencing of transcription. As this is a family of enzyme there are many types of DNA methyltransferases which are DNMT 1, DNMT 2, and DNMT 3 each one having their own function [Simmons, 2008] [Fakhr, Hagh, 2013]. There are two types of DNA methylat ion these are 1) Hypermethylation and 2) Hypomethylation. Hypermethylation stops transcription in the promoter region of suppressor genes which ultimately lead to gene silencing [Das Singal, 2004]. The location at which hypermethylation occurs at are known as CpG sites, these are sites were cytosine is next to guanine. It is the cytosine in these CpG sites that are usually methylated and therefore switched off [Esteller, 2002]. Hypomethylation is the loss of methylation at regions or sites that are normally heavily methylated, for example satellites like SAT 2. The loss of the methylation at SAT 2 can lead to instability and oncogene activation (Jin, Li Robertson, 2011). Oncogenes when activated increases protein expression which in turn leads to increase in cell division, decreases in cell differentiation and the inhibition of cell death [Chial, 2008]. It is the mutation of a proto-oncogene by hypomethylation that makes an oncogene which is the cause of increase in cell division and therefore the cause of an abnormal growth of cells that leads to tumours and cancer. A proto-oncogene is the normal, non-mutated gene that regulates cell division making it controllable by balancing cell growth and death. There many types of proto-oncogenes these include WNT, RAS and ERK [Chial, 2008] [Torry, Cooper, 1991]. To summarise the idea of Epigenetics is the control of gene expression using DNA methylation or Histone modification. If any of these two processes are damaged or mutated this then means the control of gene expression can no long be controlled and so this leads to increase in cell growth and therefore tumours and cancer. Methylation of Promoter Region The DNA methylation of the promoter region within genes is as stated an epigenetic event that is linked to transcriptional silencing in cancer. This means that DNA methylation in this region is for the control of gene expression [Yang Park, 2012]. The promoter region of gene is a region that starts or causes the initiation of transcription [Gordon, Chervonenkis, Gammerman, 2003]. The process of methylation in the promoter region causes the expression of genes to reduce or in the in case of cancers cause the silencing of the gene altogether. There are two ways that this happens in the promoter region. One of the ways it can occur is the inhibition of sequence-specific transcription factors which contain CpG sites. The second way is by the use of methyl-CpG binding proteins which can compete for binding sites of methylated DNA [Robertson Jones, 2000]. E-cadherin was introduced to have a key role in epithelial–mesenchymal transition. If there is methylation more specifically hy permethylation in the promoter region of the E-cadherin then this can cause the silencing of the gene which has been linked to many types of gastric cancer also known as stomach cancer [Tamura, Yin, Wang, 2000]. Another gene that is important and methylation of it has been shown and linked to astrocytic brain tumour is the Methylguanine-DNA methyltransferase (MGMT). Methylguanine-DNA methyltransferase’s function is as a repair protein that can remove promutagenic alkyl groups’ guanine in DNA. DNA methylation in the CpG Island of the Methylguanine-DNA methyltransferase means that its function in order to remove promutagenic alkyl groups is decreased [Nakamura, Watanabe, Yonekawa, Et.al, 2001].

Impact of ICT on the community Essay

Southall is located in a town of London borough of Ealing it is close to Heathrow airport which is one of the busiest airports in the world, which creates lots of jobs and large number of Southall residents are employed in Heathrow. Southall is quiet a small area but holds a large amount of population. Southall is one of the busiest places in England. In this area the route of communication such as, railways and roads need real improvement because at the moment they are not good enough and doesn’t meet the needs of the community really well. There is also project going about trams but our community is not happy with the decision made by the Ealing Council. In Southall it is very difficult to settle down for a person who has just been to this town because there are no enough jobs for people to do and those with jobs are paid very less wages compared to national average wage. Southall also has a very low reputation is attracting the visitors to the town, that’s because of the low employment rate. Basically this means that the people with business should give others a chance to work and pay them the same amount of wages like other employees are being paid in other towns and countries. This town is one of the towns in England which has most problems with public transport because there are very few buses to go around and the population is bigger if a bus comes early the person still can’t reach his destination in time because of the traffic. This means that the local governors of Ealing must improve the services to keep the people in the community happy and to attract more people in the town. In Southall there is also quiet a lot of traffic but mostly it’s controlled by CCTV, there is also speed limit but the residents in our community don’t follow the rules. Southall is primarily an Asian residential district, and is informally known as â€Å"little India†. Over 55% of Southall’s population of 70,000 is Indian/Pakistani. One of the Sikh Gurdwaras in Southall won the Ealing Civic Society Architectural Award in 2003. There are a few Christian churches and there are few mosques as well. The main street in Southall is called The Broadway. Southall contains the largest Asian shopping centre in the London area. Southall was the main location for the film Bend It Like Beckham. Southall is also the location of the Glassy Junction, which serves several Indian draught beers and was the first pub in the UK to accept payment in Indian rupees. Recently Southall has become notorious for the amount of violence caused by Tamil gangs and the consequences on the community. South India and Sri Lanka have been brought to the United Kingdom. There have been many shootings and other incidents that have been connected to Tamil gangs. In origin this rivalry was caused by rival politcal groups vying for power. However many of these groups have now formed street gangs abroad and resort to violence to gain power. Percentages of group per authentic group Indian: 50.3% White: 29.8% Black: 7.5% Pakistani/Bangladeshi: 7.2% Chinese: 0.2% Others: 4.9% Needs of my local Community > Banks > Sports and Leisure > Public Transport > Schools and Colleges > Medical Centre > Hospitals > GPS > Internet Cafà ¯Ã‚ ¿Ã‚ ½ > Information Point > Security CCTV > Southall community Website > Fire Department Every Community have needs and they have to meet Banks My community needs banks and ATM machine as people needs to keep their money secure people can also withdraw money from the ATM machines they need ATM because they can skip queues. The people can withdraw money from the ATM any time; it also provides us with a mini statement and gives you many more options. People in our community need to skip queues so they can have a service that’s give you all the detail about your bank online. Sports and Leisure Centre People in my community need to stay healthy and eat balance diet so the Leisure centre provides them with pre-booking and computer readable cards. It also gives help about eating healthily and gives information about other sports for e.g. Cricket, Karate, and Football etc. My community also need to know what activities are taking place and how to book it. My Community need to know where is the nearest leisure Centre and about the costs. Public Transport People in my community need Transport for moving and travelling around the city. My community provide use of Oyster card which is machine readable so they don’t have to wait in the queue for waiting to get inside and Oyster pre-pay. In addition we need to have ICT technologies in our transport for e.g. CCTV cameras so the passengers are safe and every moment is recorded. People need countdown timer which will tell them what time will the next bus come and which bus will come. My community also need a replacement service if one bus has a mechanical fault they need to have another bus at that time which will take the passenger. Schools and Colleges My Community needs to have schools which would provide basic education to younger generation. Students in schools need computer and internet access. Schools in our community need computers so they can keep record of every students and staffs to keep the school on track. Schools also need CCTV cameras to record student’s behaviour and don’t cause trouble. So the community will need computer and ICT to stop the students causing trouble. Health Centre People in MY community also need health centre to be provided with quick efficient service. Health centre will need to provide people with easy services and making registration. Health centre in Southall should have better ICT facility they should be given a choice to book on the phone. An also they shouldn’t take time to give an appointment. Internet Cafà ¯Ã‚ ¿Ã‚ ½ Every person in my community doesn’t have access to the internet. Some might not even have computer. People in my community are multicultural and came from other countries so they will need to communicate with their relatives in a cheaper way so internet cafes will meet their need. They need ICT that provides them with cheaper internet and let them have access to internet with cheaper offers as well. Southall Community Website Most of the people in my community will need to know widely about their community events and businesses in the community so the Southall website also provide information about the leisure and sport, religion, culture and businesses in the community. My community need ICT facilities to provide people with better services and keep people up to date about the events in our community. Police Station My community need to be safe and secure and police also need to try protecting people from theft, robbery and murder. My community needs good technology to keep record of crime and CCTV, so it needs ICT technology to keep records and solve people’s problem. In the above the need of my community some are more important than others. For my report I will need to look in detail of five of them. I will also need to describe the way it is used in my community. I have to define each technology and the use of the technology. I will look at the technologies that are used the most and have effect on my community. I will look at technologies that affect the whole of my community not a single person. I will also need to include how people benefit from using the service. And finally I will then evaluate how the technology will meet the need of my community. In my coursework I will write about those technologies which are in the most need and has impact on my community. Financial Transaction- Banking Definition of ATM: ATM stands for Automated teller machine is computerized telecommunications device that provides an agents customer a secure method of performing financial transactions is a public space without the need for a human teller. Using an ATM, customers can access their bank accounts in order to make cash withdrawals or credit card cash advances and check their account balances. Many ATMs also allow people to deposit cash or cheques, transfer money between their bank accounts, pay bills, or purchase goods and services. Explanation of the technology Banking is the biggest place in the world that uses ICT. ICT is used in ATM Machines (electronic funds transfer at point of sale). ATM is used to withdraw money there are also other facilities that ATM machines provide other facilities for example: you can print or view balance on the screen, change pin, order statement. EFTPOS helps customers to withdraw money through Debit Card it is mostly used in shopping. The customer’s card is swiped through a card reader and the merchant usually enters the amount of the transaction before the customer enters their account and PIN number. Before the customers didn’t needed to enter their PIN number now the customers has to enter it for security reasons. How does the technology meet the needs of the community? Every bank has its own ATM’s machines however the bank card works in every ATM machine. These machines meet the needs of the community as people are able to withdraw money at any time. It is also quick to withdraw money as if there weren’t any ATM machines it would have taken much time queuing in a lane and getting cash from the bank. It is quicker and reliable as the customer doesn’t need to show ID when withdrawing money from your own account. ATM machines are safe as no one can get the data from the ATM. How ATM works? ATM is simply a data terminal. Like any other data terminal, the ATM has to connect to, and communicate through, a host computer. The host computer is analogous to an Internet Service in that it is the gateway through which all the various ATM networks become available to the cardholder the person wanting the cash. The host computer may be owned by a bank or financial institution, or it may be owned by an independent service provider. Bank-owned processors normally support only bank-owned machines, whereas the independent processors support merchant-owned machines. Use of ICT in the banks > CCTV > Database > Security Alarm Evaluate on the use of ICT – good/ and bad features and also advantages and disadvantages of the technology ICT that is used in the banks is a big advantage to people working in the bank and to the public as well. ATM’s and EFTPOS services are open 24 hours 365 days in an year, this means the people in the community can withdraw money at any time so they don’t have to wait for the bank to open. Another advantage is that there are a lots of ATM machines in Southall so there aren’t big queues which is then quicker to withdraw money from the bank. People also need to skip queues in the banks so they can do banking online which helps the sort transaction quickly and efficiently. Online banking also has disadvantages as there is danger from hacker. You will need to provide your bank details so there is risk of you details transferred. In addition the people in my community can also check their bank detail by internet it can be done 24 hours a day using a computer and internet connection. It can help my community in various ways: * People in my community can pay bills from the comfort of their home or the workplace. * People in my community can also transfer money immediately to high interest accounts. * People in my community can check balances and daily transactions on line. * People in my community can set up direct debits and order stationery on line. * People in my community can get higher interest rates and are available to Internet bankers. * It is easy to shop around on line for the best interest rates and switch funds automatically. * And also in some banks the counter can speak more than one language it benefit my community as some people in my community can’ speak English. There are also many concerns about ATM and the Banks: * Small banks in my community closes or having opening hours reduced * Reductions in staffing at the major banks. * Some customers have worries about security because of possible credit card fraud. How ever there are two new banks which will be opening in the next few months one of the Bank has already opened ICIC. And the other banks is Panjab national it will help my community and the people in my community will benefit a lot because they can send or transfer money to their country quick and reliable. And also some people in my community won’t be able to read English so it will help the Punjabi and Indian people a lot but it will also help other people. How does the technology benefit my community? Modern ATMs provide customers with their bank account balance; they can issue money, print statements and even take cash deposits. Customers are able to use almost any ATM in any bank, supermarket or garage. And in this country it is normally a free service. Customers could get hold of their money without having to queue. This saved the customer’s time; it also saved the bank a huge amount of money since fewer staff was needed. The people in my community can benefit in many different ways as there are many more banks been opened in Southall for e.g. Panjab national it will benefit my community as well as the Panjabi and Indian people benefiting other people from different culture can benefit. Panjab national provide their service to my community in many different language for e.g. Hindi, Panjabi and English The people in Southall can also call the Centres where the Customers could now telephone the centre using either a free number or local cost number and find out information on their accounts without even leaving home. They can also change their bank detail. The people in my community can also access the their bank detail and information by internet they can open their account, check their balance online, move money pay bills and print statements from the comfort for their own homes. Lastly the ATM machines are free to use and most of the ATM machine are free of charge. To what extent does the technology meet my community need Without ATM people in my community will face various problems they won’t be able to send money abroad. People will also need to keep their money in their houses where they might face robbery. Buying house will be hard as people wouldn’t be able to get loan where they will need to pay all the money. ATM’s machine also play a very big role in my community banking as people doesn’t keep all the money in their pockets due to risk of theft so they need the ATM to withdraw money whenever they need. There are various ATM machines in Southall nearly every bank has an ATM in Southall Broadway e.g. HSBC, Abbey National, Barclays, Nat West etc. To some extent it doesn’t meet the needs of my community as some of the people in my community are not educated so they aren’t able to withdraw money they has to go inside the bank and withdraw money which takes time. Another disadvantage is that ATM’s and EFTAPOS provide money and can’t provide advice. Last disadvantage of ATM’s Machines and EFTAPOS is that whoever doesn’t have a bank account that person won’t be able to use these facilities. Possible development of the technology in the future They can improve the ATM machine by storing more cash so it doesn’t run out. In the past years there were frauds where the ATM machine takes your card and doesn’t give it back. They can also improve the ATM machine by having a secure place where people can’t see your Pin number or your bank details. In some places for e.g. Tesco or Sainsbury the can charge you for taking money so it could be free of charge. And the big improvement of ATM machine could be that they can have other language on the screen for e.g. Urdu, Pashto, Farsi, Punjabi, Somalian and Gujarati. They can make the ATM machine safe in the future where the ATM machine won’t need your pin number but it will need scanning of a customer’s fingerprint. Control and Monitoring- CCTV Explanation of the Technology CCTV stands for Close Circuit Television camera it is used for video surveillance. In my community CCTV is used in banks, casinos, shopping centres, streets, airports and now days it is even in the shops etc. Now it isn’t expensive people uses it at home for security. CCTV in Southall is used for security and to decrease crime it is also used as evidence. It is also used in schools which help the school to control behaviour of the students. CCTV is used by police and council to decrease crime and used it as evidence against the criminals. There are different types of CCTV cameras as some of the can turn at the bearing of 3600 and some of them are straight. There are also some cameras that have black glass cover and the people around can see which direction is the camera recording. How CCTV camera works? CCTV cameras in my area are continuously monitored at the Council’s Communications Centre. The Police are informed of suspicious incidents as they arise and can be directed to the exact location by CCTV operators. Since CCTV has been introduce in our community and in the borough, Southall crimes have been decreased for e.g. shoplifting, Pick Pocketing, Possessions of Drugs and unauthorised taking of motor vehicles. The control room for CCTV is in Ealing Town hall they are responsible for round the clock monitoring of over 337 CCTV cameras are fixed and 20 mobile cameras. The cameras can pan, tilt and zoom to record the action, and radio link with police make sure that the cameras are capturing the right footage. How does the technology meet the needs of the community? CCTV is used in various and different places in Southall, some CCTV cameras in my community are located in Southall Broadway and in High Street it control Anti Social Behaviour and some people drive over the speed of the limit it meets my community needs as it makes it easier to stop crime and record what has been happening it is also helps in controlling crime on the streets and shopping centres. It is used in streets to help the police catch crime and use evidence against trouble makers. It is also used in traffic lights which helps the police catch people who passes red lights and charge penalties those against who breaks the law it meets community needs as it decreases crime. CCTV cameras in Southall are able to zoom in and zoom out as it makes it easier and clearer for police and staff in the community to see what is happening. They are also computerised this means that it can record for some days and it can be used as an evidence. CCTV is also meets the needs of the community w hen it comes to use against criminals it helps my community as it produce a clear picture of the place where it is placed. It meets my community needs in a better way because every community needs to be as secured as it can be, in Southall CCTV is used in several places which meet the needs of the people and community as it provide security and records every thing is happening around. It also helps police in the as one of the CCTV cameras are able to rotate at 360 degrees which helps the police check around direct through the camera. Evaluate on the use of ICT – good/bad features (advantages/disadvantage of the technology The introduction of CCTV cameras in my community has been one of the best weapons against crime in the Borough and in this community. It has been proved effective in both cutting and detecting crime and because of this people now feel safer when they’re out and about. CCTV cameras are a big advantage for my community. If my community didn’t have CCTV the crime rate would be high and people will be free to cause trouble in my community. It will be hard for the police to find evidence and use it against the criminals in the court. People also wouldn’t feel safe in shopping centres and also when traveling. CCTV cameras can deal with everything from murder to suicides, rapes and paedophiles, although they are very rare. CCTV cameras in my community are also used in shops and supermarkets which help the customer buy stuff safely and securely and it also helps the shop owner and use CCTV evidence against thieves. The crimes that have been tackled in my community by using CCTV cameras are: * Shoplifting * Pick Pocketing * Possessions of drugs * Assault * Unauthorised taking of motor vehicle * Public order offence CCTV is a tool that saves a lot of time. Aside from the disadvantage of not attending school, youngsters can also get into serious trouble if they hang around unsupervised on the streets. So CCTV is the best technology to catch them. Some teenagers in South all are not scared of CCTV cameras as when they are doing graffiti in bus stop and damaging the environment they don’t stop, they carry on causing more damage. And when someone inform the police the operator attend the call then he tell the police about the incident and then they will deal about the incident so it’s a long process for the police to come and deal with the incident and it also cost a lot of money repairing the damage. How ever if there are more CCTV cameras placed in Southall there will be less police on patrol so it won’t cost the council a lot of money. CCTV cameras can also help my community to catch domestic and trade litterers in the act as the Council tries to get the message of Project Street clean across and those who refuse to pay their fines will end up in court. CCTV cameras are also use in Southall Railway station and it’s safer for the community to travel at night time. If people cause trouble they can call in back-up from officers to stop antisocial behaviour immediately and arrest offenders on the spot. They can also stop people intent on harming themselves. There are suicides on railways Southall station so they can stop people committing suicide. There are many advantages of CCTV cameras but there are also disadvantages CCTV increased the workload of officers. Most of the CCTV cameras in Southall are black and white colour so it doesn’t have a good quality picture. How does the technology benefit my community? CCTV benefit my community if my community doesn’t have CCTV the crime rate would be high and people will be free to cause trouble in the community. People also wouldn’t feel safe in shopping centres and also when travelling. CCTV cameras are also used in shops and supermarkets which help the customer buy stuff safely and securely and it also helps the shop owner and use CCTV evidence against thieves. CCTV cameras are place in various places in Southall most of them are placed in Schools, shopping centres, supermarkets and busy roads. It would benefit the community if they use CCTV on busy roads because some drivers drive over the limit of speed. So it’s easy for the police to catch them. To what extent does the technology meet my community need To some extent CCTV cameras meet my community needs as they can control anti social behaviour and also if they wouldn’t had CCTV cameras so people would be free to cause trouble. To some extent it doesn’t meet my community needs as most of the cameras aren’t very clear and they are placed in one place so it can’t move round as it makes it hard for the police to see around and they will need to place more cameras. Most of the advance cameras are expensive so overall it cost lots of money to install it in the community. And some time it won’t sort out some people who are causing trouble and damaging the environment. As I explained in Page 10 it’s a long period for the police to arrive and deal with the problem. The police won’t be able to catch the people but they can use the evidence of CCTV in the court. Possible development of the technology in the future They can improve the CCTV for the future as in Southall most of the CCTV cameras are black and white colour and have a poor quality so they can replace the old cameras with the latest CCTV cameras. They can have more CCTV cameras in the railways so people don’t commit suicide and already in the past the number of suicide has decreased.

Without Learn Direct my community will would have lack of education and uneducated people will still be having problems in the community.

To what extent does the technology meet my community need To some extent it doesn’t meet my community needs as some people who come to this country and they are in this community they really need help and advice and most of them don’t know about Learn direct. Some people in my community don’t know how to use computer so they will need another person to show them. Most of the people in my community also don’t have access to computer so they will have to use library and library is not open all the time. Possible development of the technology in the future They can help my community in the future in different ways. All the staffs in Learn direct speak English so some people in my community might need help and they can’t speak English and read English so the staff should be able to speak more than one or two languages as in our community some people can’t speak English. And also there should be more advertising of Learn direct and in different languages so people can find about it easily. Communication – Information Point Explanation of the Technology Information point are screens based in various places it provide a direct link to the council, free email, BBC news and sport, transport information and job search facility. It is free and every one in my community can use it. Information points provide users with local, national and international news. It also allows the user to use free email facility. It helps the people my community to communicate with other people and it lets them access to internet and search for jobs. How Information Point works?

Information Points are located in various places in Southall for e.g. it’s located in Southall Broadway Information points are widely used by the people in my community.

Users benefit from the opportunity to access what they need, where and when they need it. The Information Multipoint broadcast screen provides an effective communication tool for councils as they can be used to promote local services to citizens, such as Real-Time Passenger Information for local transport. In addition an Information Point network ensures the most appropriate services to suit the needs of citizens are available, e.g. council, government, transport and local news services.

And also some people might don’t know about the Councillor of Ealing they can get information about them and also when they have to elect a new councillor they can vote by using the Information Point. The disadvantage is that some of the information Points in my community not weather-proof and resistant to vandalism. How does the technology benefit my community? It also meet makes it easier for people in Southall to search for a job at anytime as there is more unemployment. It also meets the needs of the community as the council won’t have to employ more staff. In order to provide Outdoor broadband service for everyone in our Community Information point provides network of interactive touch screen internet-based services on-street. They are free and easy to use. As I said above that unemployment rate in Southall is high and it would be hard for people to find jobs and read news and reviews.

They can improve for the future by keeping clean and in a safe place because people in our community do graffiti and break the glasses. People in my community don’t look after the information point so the grand council may not introduce any more information point in Southall and other places. Data Capture – Bar Code Scanner Explanation of the Technology Bar Code scanner is specialized for reading bar codes. Bar Code readers are used in various places in my community for example, supermarkets, leisure centres, community centres and local shops. It allows people to buy stuff from supermarkets easily and also they get receipt. How Bar Code scanner works? A barcode reader is a computer peripheral for reading barcodes printed on various surfaces. Bar code scanner is like a flatbed scanner, it generally consists of a light source, a lens and a photo. Additionally, nearly all barcode readers currently produced contain decoder bar code scanner send the information to the computer and it prints the receipt. As I have show a picture of a Bar code scanner on the left they cashier scans the product and the scanner send all the information to the computer. How does the technology meet the needs of my community? Bar code Scanner meets the needs of my community as it convenient for the people of my community. It also helps as cashier can’t cheat with their customers as they can’t charge people higher price which all computerised and all the cashier has to do is to scan it and the customer will receive the receipt which say the price. Evaluate on the use of ICT – good/bad features (advantages/disadvantage of the technology Bar Code scanner is used in various places in my community it is mostly used in Supermarkets, leisure centres and the big stores like Tesco, Sainsbury and Asda. It is used for various purposes e.g. in leisure centres they have provided their customers a membership card which has bar code scanner and when it is scanned all the information comes up on the screen with the picture of the person which helps them to identify the person, in supermarkets it used for products as every product has bar code which is brought to the cashier and it calculates the total price and it also prints out a receipt.

It is used by every single person in my community. It meets the needs of the community as it makes it easier for people to buy stuff efficiently and quick it also gives them a prove (receipt) which is then used to refund stuff which damaged. There are also some disadvantages of Bar code scanner Bar code scanner is when it’s scan a bar code, the cursor has to be in the correct input data field, and in the correct application otherwise the bar code data will end up in whatever application that is active. This can cause all sorts of problems. Bar code scanner is also more complicated to use as it is hard for new cashier to use and it give the wrong detail to the person who purchase the product and it can cause a lot of problem to the cashier and also to the buyer.

There are many different type of Bar code scanner for e.g. Laser Barcode Scanners This is the most popular bar code scanner. A laser bar code scanner need not be close to or touch the bar code to do its job. A standard range laser bar code scanner can read a bar code from about 6 to 24 inches away, and a long range scanner can read bar code from about 2 to 8 feet away. An extra long-range scanner can read a bar code 30 feet away. Laser barcode scanners vary in price from $200 to $2,000 and come in a variety of models. Future Developments ICT needs to be improved for the new generation. It is hard to cope with the old technology for the new generation. For example community will need more telephone boxes on the streets they will also need to improve the facility for example some of them has the e-mail and news facility. Learn Direct will also need to improve as in the past the population of the community was less now it increased so they need to provide more centres and also more courses to give a wide choice. Community will also need to put more CCTV cameras on the streets as the crime rate increased and to put better quality cameras. My community also need to improve the transport it takes normally about 15 to 30 minutes for a bus to come. To meet the needs of the community in the future the technologies needs to be updated and improved so it will meet the community needs in a better way.

To Be, or Not to Be Shakespeares Legendary Speech

Even if you have never seen a Shakespeare play, you will know this famous Hamlet quote:  Ã¢â‚¬Å"To be, or not to be.† But what makes this speech so renowned, and what inspired the worlds most famous playwright to include it in this work? Hamlet â€Å"To be, or not to be† is the opening line of a soliloquy in the nunnery scene of Shakespeare’s Hamlet, Prince of Denmark. A melancholy Hamlet is contemplating death and suicide while waiting for his lover Ophelia. He bemoans the challenges of life but contemplates that the alternative—death—could be worse. The speech explores Hamlet’s confused mindset as he considers murdering his Uncle Claudius, who killed Hamlets father and then married his mother to become king in his place. Throughout the play, Hamlet has hesitated to kill his uncle and avenge his father’s death. Hamlet was likely written between 1599 and 1601; by that time, Shakespeare had honed his skills as a writer and learned how to write introspectively to portray the inner thoughts of a tortured mind. He would have almost certainly seen versions of Hamlet before writing his own, as it pulls from the Scandinavian legend of Amleth. Still, the brilliance of Shakespeare’s take on the tale is that he conveys the protagonists inner thoughts so eloquently. Family Death Shakespeare lost his son, Hamnet, in August 1596, when the child was just 11 years old. Sadly, it was not uncommon to lose children in Shakespeare’s time, but as Shakespeare’s only son, Hamnet must have forged a relationship with his father despite him working regularly in London. Some argue that Hamlet’s speech of whether to endure the tortures of life or just end it could offer insight into Shakespeare’s own thinking in his time of grief. Perhaps that is why the speech is so universally well-received—an audience can feel the real emotion in Shakespeare’s writing and perhaps relate to this feeling of helpless despair. Multiple Interpretations The famous speech is open to many different interpretations, often expressed by placing emphasis on different parts of the opening line. This was demonstrated comically at the Royal Shakespeare Companys 400-year celebration performance when a range of actors known for their work with the play (including David Tennant, Benedict Cumberbatch, and Sir Ian McKellan), took to instructing each other on the best ways to perform the soliloquy. Their different approaches all exhibit the different, nuanced meanings that can be found in the speech. Why It Resonates Religious Reforms Shakespeare’s audience would have experienced religious reforms where most would have had to convert from Catholicism to Protestantism or risk being executed. This throws up doubts about practicing religion, and the speech may have posed questions about what and who to believe when it comes to the afterlife. To be a Catholic or not to be a Catholic becomes the question. You have been brought up to believe in a faith, and then suddenly you are told that if you continue to believe in it you may be killed. Being forced to change your belief system can certainly cause inner turmoil and insecurity. Because faith continues to be a subject of contention to this day, it is still a relevant lens through which to understand the speech. Universal Questions The philosophical nature of the speech also makes it appealing: None of us know what comes after this life and there is a fear of that unknown, but we are all also aware at times of the futility of life and its injustices. Sometimes, like Hamlet, we wonder what our purpose here is.
