Robert Smithson and Ana Mendieta Essay Example | Topics and Well Written Essays - 750 words

Robert Smithson and Ana Mendieta - Essay Example The paper "Robert Smithson and Ana Mendieta" discovers the art of the two artists, Robert Smithson and Ana Mendieta. Both artists use the earth as their medium. The only difference that we can see to them is the way by which they choose the medium to present their art. Smithson in his works tends to make monumental creations. His wonderful idea about making land into a form of art motivated him to come up with the Spiral Jetty in Salt Lake Utah in 1970. Eventually he became the proponent of Earth Art or land art. He called this as a site work, wherein the mere place or location becomes the artist medium or subject. Mendieta’s approach is almost the same. She also uses the earth and other things like feather etc. as her medium. The only difference that we can see is that she does intend to make monumental creation or big work as what Smithson is doing. She is unique in her symbolic approach in visual representation. She does not concentrate in making the site as her subject and medium. She mainly incorporates herself or her body to her art. These are things that Smithson has not done with his work. Most of his concepts revolve on his conceptual ideas of making the mere place or site as a form of art. There are reasons for these differences. Ana Mendieta strives not only to present a piece of art, like what Smithson is doing. Her concept is feministic, therefore bringing her earnest idea into the mediums by which she is using. She makes a lot of symbolisms in her work than what Smithson has done.

A Positive Impacts on Patients and Society as a Whole Essay

A Positive Impacts on Patients and Society as a Whole - Essay Example I have critically evaluated the nature of the nurse practitioner professional and am certain that I am equal to the task. I am certain that I have the ability and commitment to perform those responsibilities with enthusiasm and professionalism. I understand that the nurse practitioner is allowed to provide a wide range of health care services. The first health care services that nurse practitioners are allowed to provide is taking the patient’s history, physically examining the patient, as well as ordering laboratory procedures and tests. The second one is to diagnose, treat and manage diseases. Thirdly, nurse practitioners are allowed to write prescriptions and coordinate referrals. In addition, nurse practitioners are allowed to provide handouts about healthy lifestyles and disease prevention. The final main responsibility of nurse practitioners is to perform specific procedures such as lumbar puncture and bone marrow biopsy. As I seek to lead a purpose-driven life as a nurs e practitioner, I am fully aware of the variety of settings that as a nurse practitioner I can work in. these settings include neonatology, emergency, oncology, women’s health, paediatrics, cardiology, geriatrics, school health, family practice, primary care, and nephrology. I am also aware that I will be sometimes required to work in clinics in the absence of doctors’ supervision, while at other instances I will be required to work together in a joint health care team. More Importantly, I understand that I will be required to work within the authority and scope of state and federal laws.

Key Benefits And Limitations Of LCA Environmental Sciences Essay

Key Benefits And Limitations Of LCA Environmental Sciences Essay Major benefits can arise from LCA. Through the ability to analyses exchanges that take place in the environment, it enables decision-makers to select the product or process that result in the least impact to the environment. LCA data identifies the transfer of environmental impacts from one media to another and/or from one life cycle stage to another (EPA 2001). Quantification of emissions, detection of variation between the various life cycle phases, the ability to estimate environmental burden of materials, the ability to compare and contrast competing products and the potential to structure and improve the flow of data between stakeholders are just some of the obvious benefits that can be gained through adoption of LCA. Papers by Deloitte Enhancing the value of life cycle assessment and Lifecycle assessment: where is it on your sustainability agenda? provide an insight into several benefits from utilizing LCA, including (Deloitte, 2009): Innovation: Through revealing the source and magnitude of environmental impacts, product level LCA data can inform the innovation agenda. Cost savings: Clarity in relation to cost drivers can lead to increased efficiency via material and energy requirements minimizing the negative environmental impacts. Furthermore, certain investments in RD and projects related to renewable energy may be eligible for tax credits or other incentives. Internal alignment: LCA provides a common ground for internal goal-setting and communication. Different departments within an organization can unite on enterprise-wide priorities. Regulatory preparedness: LCA can help quantify the projected product cost implications of future carbon legislation and flag those areas that warrant immediate action. LCA can also enhance general transparency to deflect scrutiny from regulators and other stakeholders. Corporate reputation: LCA can demonstrate a companys deeper commitment to improved environmental impact. Improved sustainability claims can strengthen stakeholder relations. Risk reduction: LCA helps companies develop their position around environmental issues to which their operations contribute. Increases awareness of potential liabilities the company should be aware of. On top of these benefits examples of how customized LCA studies can support significant sustainability objectives include (Deloitte, 2012): Enhance brand value for competitive differentiation: Compares the environmental impact of an organizations product to alternatives to determine which benefits are distinguishable. Improve design decisions: Evaluates resource and materials use to inform product and process design decisions that increase environmental efficiencies. Make better procurement decisions: Engages multiple stakeholders and suppliers to allow organizations to make procurement decisions that significantly boost their sustainability efforts. Meet communications needs: Provides a platform for authentically communicating positive environmental attributes about products to buyers and consumers. Achieve compliance: Addresses regulatory mandates at local, national and international levels. Create better policies: Evaluates internal and external policies of the organization to determine realistic objectives. While all of the above benefits help paint a positive picture of LCA, one also has to consider the various disadvantages or limitations of such systems. As with all new and evolving systems there will always be significant teething problems during development. The more noteworthy of these include the fact LCAs utilizing the same and different methodologies can have vastly different results with assumptions, which can be subjective, being a requisite even for simple comparisons to be carried out. The validity of data is always a concern and whether the most up to date data has been used. Performing LCA is resource consuming and gathering data can be problematic. As a result, it is essential to weigh the resources needed against the projected benefits to measure feasibility. There is still no widely accepted standardised format for LCA, with most of the already existing ones such as ISO 14040 having several imperfections. Finally results of LCAs focused on national and regional level m ay not be suitable for local applications. These limitations do take some of the shine away from LCA and indicate that in essence at present LCA is fundamentally flawed given it can be near impossible in many cases to know the validity and relevance of conclusions drawn by the practitioner. While this may be true what has to be consider is that LCA is the best tool we have at present to tackle this significant area of concern. In reality the benefits of LCA far outreach its flaws and as transparency of methods and data becomes the norm its integrity will increase. What is for certain is LCA is set to become a fundamental element of product and service design. Applications and potential of LCA Applications of LCA The application of LCA has been well documented and includes supporting initiatives to assessing environmental impacts that need addressing. Studies (Frankl and Rubik, 1999; Frankl et al., 2000) have highlighted key areas of application including: Bottleneck identification Information and education to consumers and stakeholders Compare existing products with planned alternatives Compare existing company products with products of competitors Procurement specifications, supplier screening, product co-makership Internal information and training Anticipate and negotiate legislation Marketing, advertising policies joining eco-labelling criteria Environmental cost allocation Assess the gap from eco-label criteria Radical changes in product life cycle What can be taken from these findings is that there are three principle areas of application are; (1) comparison on an environmental basis which includes comparison of materials, methods and conformity. (2) In manufacturing LCA can be used to find the most ecological method through optimal material and processes selection. (3) In commercial development LCA can be used for marketing purposes and as a public informational aid (in example EPDs). In reality there are many different views among the scientific populace as to use and best practice for LCA. What is of interest is that one article by Grantadesigns in 2011 called Grantas new Guide: Five Steps to Eco Design proposed that up to 80% of the environmental footprint of a product is determined during the design phase. From this we must assume that the best application for LCA would be in the design phase via evaluation of design alternative. Potential of LCA LCA is a methodology for quantifying and assessing the potential impacts of goods and services from an environmental perspective. From this viewpoint it can be taken that LCA can be applied to any kind of product or decision where environmental impacts are of concern. This in turn implies LCA can be applied by all the different stakeholders who are invested in a product or service including governmental, non-governmental and industries. While this dissertation cannot elaborate on all the opportunities open to LCA, focus will be placed on the following areas which are of particular interest to this study: The potential of LCA at multinational corporation level The potential of LCA for small and medium sized enterprises (SMEs) The potential of LCA at governmental level The potential of LCA for multinational enterprises Multinational companies face important strategic decisions that help establish the direction of their environmental performance. The decision whether to adopt a global standard or not is one such decision. While specific characteristics of multinationals make the application of LCA easier including; dedicated resources made available, separate departments responsible for implementation and co-ordination, development of internal databases and operating methodologies, and the ability to influence stakeholders, among others; there are equally other factors which present significant challenges including; diverse cultural approaches and consensus on methodologies including weighting across impact categories (Schmidt and Sullivan, 2002; Reap et al., 2008), and how to integrate LCA across the whole organisation as LCA in general tend to be reserved to environmental departments. The value which can be extracted by large corporations who adopt LCA tends to be in terms of material choice, tech nology choice, infrastructure and location choice, and product and process improvement. The potential of LCA for small and medium sized enterprises (SMEs) While the need for environmental practices have been widely accepted in SMEs, as can be seen through the widespread adoption of ISO 14001, the adoption of LCA has being met with less enthusiasm. This is largely to do with the fact most SMEs need to focus their available resources on establishing their position in the market and cant afford to extend resources to non essential activities. However, many small and medium enterprises are now seen the economic benefits that can be reaped from LCA implementation via simplified low cost approaches. Significant advantages can be gained in the RD stage of products via material swap outs, process improvements or benchmarking (Hunkeler, 2003). One could even go as far as to say that LCA can be useful to improve credit terms as it improves resource allocation and minimises the risk of resources being spent inappropriately. The tangible benefits with regard to environmental business policy include (Hunkeler et al., 2004): reduced operating cost, improved resource efficiency, improved relations with authorities, improve external image, improved credit terms and reduced overheads. It is also worth noting that the addition of LCA will add value for firms in their IPO (initial public offering) as it will be recognised that the company will be more likely to be sustainable with future environmental requirements. The potential of LCA at governmental level The pattern to which goods and services are produced and consumed is established and controlled via government regulated frameworks and conditions. LCA falls within the reams of sustainable development and is of key importance in addressing waste and emissions attributes of products and services. Government activities are ongoing in regards to LCA with supporting strategies becoming widespread. This has led to the development of several nationally managed databases along with new methodologies and tools. Government bodies, including the departments of environment, energy and defence etc., are now active in supporting LCA development via conducting case studies and making data available. Websites have been developed and product orientated environmental policy is evolving, none more so than in the European Union (EU). In its Communication on Integrated Product Policy (COM (2003)302), the European Commission concluded that Life Cycle Assessments provide the best framework for assessing the potential environmental impacts of products currently available. There is an understanding within the EU for the need of life cycle thinking in stakeholder consultations and in policy implementation. There is an acknowledgment that information from LCA can support public policy making in eco-design criteria setting, such as contributing to performance targets within the Environmental Technology Action Plan (ETAP) and for energy-using products within the EuP Directive, in green public procurement (GPP), and in environmental product declarations (EPDs) (European commission, 2003). However, consideration has to be giving to the fact that LCA is only a decision supporting tool, and not a decision making tool. While advances aid its progression it is still limited with regards economic and social impacts, along with local environmental issues. As a result it can only be utilised in support of other tools to aid detection of potential improvement areas. Policies, Laws, Standards and Incentives Life-cycle analysis (LCA) is not a new phenomenon with scientists and manufacturers increasingly using it to expose opportunities to reduce environmental impacts of products and services, from cradle to grave. This has led to the rise of policies, legislation, standards and incentives in the race to control and maximise the potential of this rapidly expanding sector. Policies LCAs offer the opportunity to shift the traditional policy basis away from waste and resource amounts to one where the potential environmental impacts they cause is the focus and in so far as is feasible the related consequences to humans and the ecosystems is catered for. Laws While traditionally focus has been on reducing impacts of production processes, the responsibility is now being extended to manufacturers to reduce the impacts of products as well. This extension of manufacturers responsibility to cover the entire lifecycle of a product is known as Extended Producer Responsibility (EPR). The EC Sixth Environmental Action Programme Environment 2010 emphasises the importance of product policy which is also reflected in the Integrated Product Policy. Standards The International Organization for Standardization introduced the ISO 9000 series quality management standards in 1987. These were later followed in 1992 by various environmental standards known as the ISO 14000 series. These voluntary standards require verification by an external certification body to obtain the ISO certificate. In the ISO 14000 series there is a family of standards to choose from, so when you want to get environmentally certified you need to consider which best matches your requirements. The point of note in relation to the ISO 14000 series is that it is generic, meaning any business, regardless of size or sector can apply. The following provides a brisk overview from a European perspective of the main policies, laws and standards where the life-cycle approach is emphasised as an important element. Table : Overview of relevant policy, law and standards (Developed with data from European commission and Irish department of environment) Designation Class Foundation Title Subject matter Policy Framing policy 06/2008 Sustainable Consumption and Production Action Plan, (SCP) This communication sets out the measures to deliver more sustainable consumption and production, while improving the competitiveness of the European economy. It builds on several EU policies including the renewed Sustainable Development Strategy. The Community Lisbon Programme for 2008-2010 includes the promotion of an industrial policy geared towards more sustainable consumption and production as one of its major orientations (European commission, 2008). Framing policy 12/2005 EUs thematic strategy on the sustainable use of natural resources The objective is to reduce environmental impacts linked to resource use in a growing economy enabling sustainable development (European commission, 2005a). A review carried out by the Bio Intelligence Service in 2010 indicates the integration of key concepts conveyed by the resource strategies have had a positive but partial influence with the clear need for clear objectives and targets, and the establishment of data centre for natural resources being highlighted (Mudgal et al., 2010). Framing policy 12/2005 EUs thematic strategy on prevention and recycling of waste Describes a number of key objectives as part of an evolving EU policy on waste including; Prevent waste, Promote re-use, recycling and recovery; and Establish the European recycling society. The aim of this strategy is to reduce the negative impact on the environment that is caused by waste throughout its life-span, from production to disposal, via recycling. The objective is that every item of waste is seen not only as a source of pollution but also a potential resource to be exploited (European commission, 2005b). Framing policy 06/2003 Communication Integrated Product Policy (IPP) Aims to support the realisation of environmental product innovations in order to achieve a broad reduction of all environmental impacts along a products life cycle (Commission, 2001). Due to the nature of products, IPP cannot consist of a single general policy instrument, a variety of measures must be employed to achieve the IPP objective (In example standards or so-called soft environmental policy instruments such as activities regarding voluntary agreements or environmental labelling.) (Rehfeld et al., 2007). European Commission, Integrated Product Policy Communication (IPP), 2003 states LCA is the best framework for assessing the potential environmental impacts of products, but the debate is ongoing about good practice with the European commission committing to; developing a handbook on best practice, Co-ordinating to make data more accessible and systematically collected, Regularly update directory of LCA databases, and develop a platform to facilitate communication and exchanges . All of the above commitments have or are in the process of being delivered. Specific instrument 2005 revised 2009 Eco-design directive Provides for improving the environmental performance of energy related products (ERPs) through ecodesign and prevents distinct national legislations on environmental performance becoming obstacles to the intra-EU trade. The ecodesign requirements must not lower the functionality of a product, its safety, or have a negative impact on its affordability or consumers health. The Directive is under the responsibility of DG Enterprise and Industry and DG Energy (European commission, 2012b). Specific instrument 2005 Energy-using products (EuP) Directive The main objective of the EuP Directive is to bring about improvements in energy efficiency throughout a products lifecycle, from cradle to grave. Its focuses on the design phase as it is considered that up to 80% of the environmental load of a product is fixed during design. EuP is a Framework Directive which outlines the legal context within which implementing measures will be developed and targeted at particular product groups (Premier Farnell, 2009). Specific instrument 1/2004 Environmental Technology Action Plan (ETAP) The plan covers a range of actions to promote eco-innovation and the take-up of environmental technologies including: promoting research and development, mobilising funds, helping to drive demand and improving market conditions. Information from LCAs can contributing to meeting performance targets within the Environmental Technology Action Plan (ETAP). In Ireland specific consideration will be given to projects that have the potential to address the three specific challenges identified in the Environmental Protection Agencys (EPA) State of the Environment Report 2004, namely: eutrophication of surface waters, meeting international commitments on air emissions and better management of waste (Department of the Environment, 2012a). Specific instrument 2008 Green public procurement (GPP) Defined in the Communication (COM (2008) 400) Public procurement for a better environment as a process whereby public authorities seek to procure goods, services and works with a reduced environmental impact throughout their life cycle when compared to goods, services and works with the same primary function that would otherwise be procured. The EU committed to aiming to achieve by 2010 a proposed a target of 50% of all the EUs public procurement tendering procedures to be green. Although this target has not been met a recent report monitoring the uptake of GPP found 26% of the last contracts signed in the 2009-2010 period by public authorities in the EU included all core GPP criteria with 55% of these contracts having at least one EU core GPP criterion, showing that some form of green procurement is being done at a large scale (European commission, 2012c). In Ireland the GPP national action plan has been developed to make half the estimated à ¢Ã¢â‚¬Å¡Ã‚ ¬15 billion in public spendi ng to meet green procurement criteria (Department of the Environment, 2012b). Specific instrument 2002 and Under review Environmental product declarations (EPDs) Environmental Product Declarations (EPDs) are life-cycle based ecolabels that disclose the environmental performance of the product, similar to nutrition information labels. In France a law was passed in 2007 the Grenelle Environment which requires environmental product declarations for all mass produced consumer goods. 2012 has seen experiments begin to establish best practice to implement this law. The European Commission is following suit and has begun a program to develop guidance on environmental product declarations indicating this will be widespread shortly. Specific Instument 1992 Eco-labelling Is in general a voluntary scheme where producers, importers and retailers can choose to apply for the label for their products. Ecolabel criteria focus on the stage / stages with the highest environmental impact during a products life cycle. By the end of 2011, more than 1,300 licences had been awarded, and at present, more than 17,000 products have the EU Ecolabel. A licence gives permission to use the EU Ecolabel logo. (European commission, 2012d). Laws Legal requirement 2003 Restriction on the use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS) Adopted in 2003 by the European Union the directive took effect in 2006 becoming law in each member state. It restricts the use of six hazardous materials in the manufacture of electronic and electrical equipment. It correlates with the Waste Electrical and Electronic Equipment Directive (WEEE) 2002/96/EC which is part of a legislative initiative to reduce toxic e-waste. Legal requirement 2002 Waste Electrical and Electronic Equipment (WEEE) The WEEE Directive 2002/96/EC is an EU Directive founded on the principle of Producer Responsibility and its general objectives are to prevent waste of electrical and electronic equipment (WEEE) and to improve the environmental performance of all operators involved in the life cycle of such including producers, distributors and consumers (European commission, 2012e). Legal requirement 2000 End of Life Vehicles Directive 2000/53/ EC of the European Parliament on end of life vehicles was developed to limit or exclude the presence of dangerous substances including lead, cadmium, chromium IV and mercury in vehicles with the purpose of minimising their environmental impact. In 2006, the target for reuse and recovery was a minimum of 85% of the materials rising to 95% in 2015 with most major OEMs such as Ford, Honda etc on the way to meeting these targets. Legal requirement 1994 EU Packaging and Packaging Waste Directive 94/62/EC This directive regulates the heavy metal content of, and recovery of any packaging put on the market. Implemented in Ireland through the Waste Management (Packaging) Regulations S.I. No. 61 of 2003 as amended by the Waste Management (Packaging) (Amendment) Regulations S.I. No. 871 of 2004. While it should be noted the directive is under review at European level, the legislation is now well developed in Ireland with waste recovery schemes like REPAK in place. Legal requirement 2007 Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) REACH came into force in 2007 with the aim to ensure a high level of protection of human health and the environment from the risks that can be posed by chemicals, the promotion of alternative test methods, the free circulation of substances on the internal market and enhancing competitiveness and innovation (European commission, 2012f). Manufacturers have to register each substance, assess the risks it poses and pass on the safety information to downstream users. Legal requirement 2006 Batteries Directive Directive 2006/66/EC prohibits placing certain batteries and accumulators with mercury or cadmium content above a fixed threshold on the market and promotes a high rate of collection and recycling of waste batteries and accumulators. The aim is the reduction of hazardous substances (mercury, cadmium and lead) dumped in the environment (European commission, 2012g). Standards Voluntary 1997 revised 2000 and 2006 Life cycle assessment: ISO 14040/44 When concerned with the environmental impact of a new or existing product, it may well be beneficial to carryout a complete life cycle assessment. In such a case you would look to the ISO 14040 certificate. It evaluates the products LCA framework and is intended to make reliable and reusable assessments. It endeavours to provide a clear overview of the findings to stakeholders, including those who have limited knowledge of life cycle assessment. The specific requirements and guidelines for LCAs are in ISO 14044. Voluntary 2001 Environmental site assessment: ISO 14015 This International Standard provides guidance on how to conduct an Environmental assessment of sites and organizations (EASO) through a systematic process of identifying environmental aspects and environmental issues and determining, if appropriate, their business consequences. Voluntary ISO 14020 1998 rev 2000 ISO 14024 1999 ISO 14025 2000 rev 2006 Environmental product declaration (EPD), Labelling: ISO 14020/24/25 ISO 14020/24/25 will help you label your product. It includes quantified data which helps ensure environmental data published is of a certain quality. These product labels are built upon the Life Cycle Assessment which means the information generated is relevant, verified and comparable. Voluntary 1999 Environmental Performance Evaluation: ISO 14031 When you dont require a certificate and just want to measure your environmental performance, this document gives guidance on environmental performance evaluation. It provides management with reliable and verifiable information on an ongoing basis through its Plan-Do-Check-Act system (PCDA). Voluntary 2002 Integrating environmental aspects into product design and development: ISO 14062 Guidance standard providing generic instruction on how to incorporate environmental criteria into product design and development. It can act as a reminder or a checklist and is applicable to all industry sectors. Other industry sectors have developed similar standards including:- Standard ECMA 341, Environmental design considerations for electronic products developed by ECMA International. EN/BSI 13420:2000 Packaging Requirements for packaging recovery by material recycling. BS/EN 13193:2000 Packaging and the environment Terminology. Voluntary 2006 Impact on Climate Change: ISO 14064 ISO 14064-1:2006 facilitates quantification and reporting of greenhouse gas (GHG) emissions and reductions. It provides stakeholders with an integrated set of tools to achieve their objectives and it enables participation in emissions trading schemes using a globally recognised standard. Voluntary/ Under construction N/A Product Carbon Footprint: ISO 14067 Strives to standardize the maze of product carbon footprint approaches. Voluntary/ Under construction N/A Water Footprint: ISO 14046 Aims to establish harmonized metrics for water footprints. Other Voluntary 2008 GHG Protocol Product Standard This is a product life cycle accounting and reporting standard developed by the World Resources Institute (WRI) and the World Business Council on Sustainable Development (WBCSD). This standard is to a large extent in compliance with ISO 14040/44, except it is explicitly focused on greenhouse gas accounting.

Anglo Saxon Literature :: History Beowulf

Anglo Saxon Literature W Y R D The word wyrd generally means fate in Anglo Saxon literature. It is one of the recurrent themes in many old English works. For example, wyrd is seen as the force that determines the result of events in Beowulf. In another story, â€Å"The Wanderer,† wyrd is mentioned several times. In the first few lines, the speaker states that â€Å"fully-fixed is his fate† (Norton 100). This shows that wyrd is unchangeable. Then, he goes on to say â€Å"Words of a weary heart may not withstand fate† (Norton 100). Here it seems that a person must be strong, brave, and show no emotion in order to be able to cope with wyrd. Later on, wyrd is proclaimed as â€Å"mighty† because not even earls are able to escape their deaths. Lastly, we see the power of wyrd: â€Å"The world beneath the skies is changed by the work of the fates† (Norton 102). This quote reflects the belief of Anglo-Saxons that wyrd is an invisible, powerful force that controls the outcome of a personà ¢â‚¬â„¢s life. This final use of wyrd may also refer to the â€Å"Weird Sisters.† They are seen in Shakespeare’s play Macbeth. The Fates are also an important part of Greek culture. Usually they are depicted as three horrid old ladies who share one eye with which they see the future. They also are seen tending to so-called â€Å"threads of life.† Each time they cut a thread another soul goes to the underworld. This portrayal of the Fates can also be related to the â€Å"Measurer† in â€Å"Caedmon’s Hymn.† The â€Å"Measurer† seems to be the one who decides the destiny of a person, just as the Fates: â€Å"The Measurer’s might and his mind-plans† (Norton 24). Like witches, the Fates are sometimes shown surrounding a large pot, brewing spells. Women were given the opportunity to pick their own husbands. The families acted merely as financial advisors. However, in many circumstances, women were married off to members of enemy tribes in order to bring peace. Hence, they were given the name peace-weavers. Women, depending upon social standing, were also educated and wise, sometimes acting as advocates and protectors of the people of the village. Over all, the women in Anglo Saxon were well respected and valued. Scene Analysis: Beowulf Fights Grendel's Mother Summary In the Howe translation of Beowulf, the scene depicted on pg. 26-29 deals with the battle between Beowulf and Grendel’s mother.

Importance of data security and data safety Essay

To prevent companies from using or passing on confidential information to other companies without the permission of the person who the data is about, companies will need to protect the data. With the popularity of the Internet there are opportunities for thieves to steal their personal data. So the government set a law (data protection act) which is used to protect people’s rights concerning how data is used and you also have the right to see such information and have any errors corrected. Also organisation will want to keep data confidential because it will not want its competitors to know how the business is going. List the 8 principles of the Data Protection Act The Data Protection Act says the personal data should: 1. Be adequate, relevant and not excessive. For example college should keep students details and details must be just what is needed and nothing more. 2. Be processed in accordance with the data subject right. For example the person that the data refers to have the right to read the information about him/her and the organisation should provide hem/her with information they need. 3. Be accurate and be kept up to date. There is a duty to keep it up to date, for example to change an address when people move. 4. Not be kept longer than necessary. For example it is alright to keep information for certain length of time but it would be wrong to keep information about past customers longer than a few years at most 5. Be obtained and processed for limited purposes. For example the organization must use the data only in the way it is described and it must not use it for any other purpose. 6. Be secure. This includes keeping the information backed up and away from any unauthorised access. It would be wrong to leave personal data open to be viewed by just anyone. 7. Not be transferred to countries outside Europe without adequate protection. Unless the country that the data is being sent to has a suitable data protection law 8. Be processed fairly and lawfully. For example if you put your money at bank no one can transfer your money without your permission. (a) What is the difference between the Internet, Intranet and Extranet? (P8) Internet: Are public networks that allow the user to use any of its facilities. Intranet and Extranet: is like a private internet. It is like a website that is only accessible to the members of a business or company. The different between Intranets and Extranet is: Intranet: Allow the members of organisation to access the access the system with an organisation. Extranet: Allow the members of organisation to access the system from different location but only by the users who have been given access rights. (b) * What is a browser? Is programme that can read web pages, by downloading HTML code and that allows the browser to interpret the code to the web page. A browser displays web pages, keeps track of where you’ve been, and remembers the places you want to return to, the most used browsers are Internet Explorer and Netscape Navigator. Describe the role of a browser when using the Internet, Intranet and Extranet Browser allows the people to access information, view images, hear music and watch video, in the term of intranet and extranet the browser allows user to share documents, access databases and allow group work. * Describe the role of email when using internet communications. You can send email to an individual or to a group of people at the same time, you can create mailing list so that you can write a message and send it automatically to number of people. Also you can send files such as pictures, word document and sound as attachments to your message. (a) List major threats to an organisation that could happen while using the Internet. (P9) 1. Hacking (use to steal the personal details and private files of company) 2. The spreading of viruses (use to destroy or damage the important files of company) 3. Internet fraud (taking credit card details from customers) 4. Spay ware (is biggest threat in the computer system which allows someone to log into your computer and use it for their own purpose) 5. Spam ( sending unwanted messages especially commercial advertising) Purpose of assignment In this assignment, I have to do research and get information on the importance of data security and data safety. M research must be from ICT sources and non ICT sources and by using the evidence that I collect I should explain the importance of keeping customer information confidential, the main provision of data protection act, the role of browsers and email in internet communications, the difference between internet, intranet and extranet, the major threats to organization from internet and finally a poster that explains the importance of data safety and data security. The assignment will also gather key skills portfolio evidence. M5 Physical Security: Use of security guards, locks, reinforced doors, windows and walls depending on what is being protected. Use of ICT to enforce security entry on doors, and protected areas of buildings i. e. : swipe cards, fingerprint ID, voice recognition. Firewall: This is a security device, which acts as a single entry/exit point for information and access to a computer system. All traffic must pass through the firewall and therefore a system is secure from external threats. A firewall usually sits between the internal network of an organisation and access by the internet. Virus Protection: It is usual for systems to have some form of anti-virus software installed and running in the background. All files and devices introduced to the system would be scanned, any attempts to alter system files would be blocked, and notification made to the user/system administrator. Preventing the use of floppy disks is a good method of eliminating one source of potential virus problems. Identification of Users: A system of user ID’s and passwords is a simple method of preventing unauthorised personnel accessing the system. These should be managed by the system administrator. With this, only some users will have access to certain programmes and data therefore increasing the level of security on sensitive data. In addition, some users may only be able to read the data and not write the data. Other users may not have the ability to delete or even to access certain files. Encryption software: the data may be encrypted (coded) into a form, which can only then be decoded by the intended user. If the data falls into the wrong hands, it will be meaningless. Backups: To guard against the loss of data, backups should be regularly made. These backups should be stored in a separate place, preferably in a fireproof environment. Passwords software: Password protection usually involves a person typing in:   A User Name – to identify the person.   A Password – to identify the person. He should be the only one to know what it is. Computer viruses: which are programs that destroy the way computer operates without the knowledge of the user, there are huge numbers of viruses some are extremely malicious with the ability to delete or damage files and programs. Some of the threats that they cause to computer systems include:   Deleting data on the hard disk of the organisation computer system.   Enabling hackers to hijack the organisation system and use it for their own purposes. How do viruses spread:   CDs and floppy disks containing infected documents. Emails containing infected attachments. Hackers: who gain unauthorised access to computer systems for the purpose of stealing and corrupting data, also gaining access to financial information about the organisation business or their customers for the purposes of fraud. Security measures may include†¦ Each user should be given a user name and a password.   Computer usage may be logged.   Computers should be disconnected from a network when not in use.   Use a firewall – a computer running software, which detects hackers dialling in to a network. Spam: authorised users downloading a web page or receiving an email with hidden active content that attacks the organisation system or send sensitive information to unauthorised people. Organisation can stop spreading of spam by using spam filtering software. Spy ware: is software that is placed on organisation computer when the employee visits certain websites, it is used to secretly gather information about the organisation usage and sends it back to advertiser or other interested company to tracking the organisation system use . it can also slow down or crashes the organisation computer Pop up: Many company advertisers on the Internet by using windows that pop up in the middle of computer screen to display a message. They might also open when you click a link or button on a Web site, and they might open either over or under the window, you wish to view. Some pop-up windows can contain inappropriate content or can be a way for employee of organisation to accidentally download dangerous software (called spyware or adware) onto organisation computer. Infringement of copyright: Internet users are not allowed to copy or print some internet materials such as; video, music, files and photos without the permission of copyright holder and sometimes they may have to pay a licence to do so. Theft and fraud: credits card fraud for example people can steal the details on credits card and using them illegally to buy goods. Sole trader: A sole trader is the actual owner of a business, a sole trader also has unlimited liability. All the debts of the business are the debts of the owner. They can not issues shares . The whole meaning behind † Sole† means that she/he does not have partners. (e. g. electrical repair, picture framing, photography, diving instruction, retail shops, and hotels) Partnership A Partnership can be liable for all debts, it is easy to setup, but is also inexpensive to form. Forming partnership requires an agreement that is some times called partnership agreement ‘between two to twenty individuals’ which entitles them to jointly own and carry on a trader business together. A partnership is a contract between two or more persons who agree to pool talent and money and share profit or loss. Private limited company A Private limited company has limited liability (the shareholders cannot loose more than their original shareholdings), and a minimum of two shareholders and a maximum of fifty shareholders. It cannot offer its shares to the public. A private limited company is treated as a legal entity. Public limited company A company which may have an unlimited number of shareholders and offer its shares to the wider public. (e. g. Cadbury and Tesco) Multi-National company A company that does business in more than one country, usually by setting up branch offices.

Discuss whether private policing can ever ensure public security

Not only is policing conveyed by an escalating array of public bodies organized at a diversity of geographical levels, but the private and municipal parts are themselves becoming more perceptible in this arena. It is far from clear, though to what degree the growth of policing services delivered by agencies other than the state police symbolizes the filling of a gap left by the incapability or disinclination of the state police to give services the public wants.It may represent changes in the nature of modern life and institutions in which the growth of these services lies along, is complementary to, the steady growth in spending on the state police and other public policing services like Environmental Health Officers or the Post Office Investigation Department.Nor is it obvious that there has been the immense growth in non-police ‘policing' which is often claimed. surely there has been a huge increase in the employment of uniformed private security personnel. owever if ‘ policing' in its broadest sense is construed to include those people who, like wardens, caretakers, park-keepers, and gamekeepers, have always been employed to guard, protect, and manage both public and private property and locations, then much of this growth may simply imitate changes in the way the task is done. What is clear is that, for a diversity of reasons, the respective roles of the police and private security organizations now increasingly be related. The boundaries between them are becoming less well defined.This is the consequence, in part at least, of a process referred to as the ‘decreasing equivalence between private property and private space'. The subsequent half of the twentieth century has seen a rapid growth in property which is privately owned but to which the public typically has access. This property includes shopping centers, built-up estates, educational institutions, parks, offices, and leisure centers. More and more public life is being performed on private property.Thus the protection of private property, a fundamental aim of private security-has increasingly come to take in the maintenance of public order as while, for example, there are demonstrations against new road construction. Private security services have intruded more and more on what used to be considered the restricted domain of the state police. The boundaries between public and private policing have further were indistinct because of the operations of an escalating number of agencies whose formal status and functional activities are hard to classify.These have most usually been referred to as ‘hybrid' or ‘grey' policing bodies. They take in, for example, the surveillance, investigative, and dogmatic sections attached to central and local government departments. The place of some of these bodies has been made even more ‘grey' by the privatization programme the government has practiced. For example the British Transport Police will persist to poli ce our railway network: they will, for the foreseeable future, give a contract service that the new railway companies have been given no option but to accept.Johsnton (1999) asserts that private policing consists of two components. ‘Commercial’ policing involves the purchase and sale of security commodities in the market place. ‘Civil’ policing consists of those voluntary policing activities undertaken by individuals and groups in civil society. The history of commercial policing in Britain is a long one, McMullan’s (1987) account of crime control in sixteenth and seventeenth century London pointing to the systematic recruitment of paid informers and thief-takers by a state unable to control unregulated areas.This is an early example of what South (1984) has referred to as ‘the commercial compromise of the state’, an invariable feature of all systems in which the commercial sector has a policing role, though one whose precise character v aries with circumstances. The private security industry is a large, lucrative, and growing part of the UK economy. Different estimates of the annual turnover of the industry are obtainable.A 1979 Home Office Green Paper suggested an annual turnover in 1976 of ?135 million and, according to the marketing consultancy Jordan and Sons, total annual sales during the early 1980s were in excess of 400 million. Jordan's 1989 and 1993 reports suggest respectively that the yearly turnover of the industry increased from ?476. 4 million in 1983 to ?807. 6 million in 1987 and ?1, 225. 6 million in 1990. One recent estimate by one of the regulatory bodies in the private security industry has put the turnover for 1994 at ?2, 827 million (Daily Telegraph, 15 August 1996).Because private security firms take up a position of trust for those who utilize them to protect their persons and property, as the evidence suggests that individuals and groups put off to people who wear uniforms intended to conju re the authority of the police, and as those who provide security services are in a position to abuse that reverence and trust, we do not think it is any longer defensible to allow the private security industry to continue unregulated. There is proof of abuse.There are undoubted cowboys on the loose and there is nothing at present to prevent disreputable and criminally-minded operators from proffering any security service they wish. Indeed, even a Government ideologically committed to reducing the amount of directive has recently come round to the view that some type of control of the private security industry is now essential. In August 1996, the Home Office announced that a statutory body to vet people wanting to work in private security was to be recognized, and that new criminal offences of utilizing an unlicensed guard and working as an unlicensed guard would be introduced.Given that these plans are both indistinct and not accompanied by any schedule for implementation. There i s currently no constitutional licensing or regulative system of any kind for the private security industry in Britain. This distinction with almost all other European countries. Britain stands practically alone in not having admission requirements for firms offering security services and, together with Germany, not setting performance rations for private security operatives. Austria, Belgium, Denmark, Finland, France, Germany, Greece, Italy, the Netherlands.Norway, Portugal, Spain, Sweden and Switzerland all have some form of governmental control over their private security industries (de Waard J. 1993). Estimates of the size of the industry in Britain have been notoriously inaccurate. However, recent research by Jones & Newburn (1998), based on data drawn from the Yellow Pages Business Classification and the Labour Force Survey, has produced far more reliable figures. Total employment in the British contract security industry now exceeds one third of a million (333,631), with emplo yment in the ‘services and equipment sector’ (which includes guarding) standing at 182,596.This latter figure, alone, is equivalent to the total number of police and civilians employed in the 43 constabularies in England and Wales. As is the case in other countries, the most rapid area of expansion is in electronic security. Indeed, out of the total of 6,899 security companies identified in the research, no fewer than 2,547 are in the electronics sector, the remainder being in services and equipment (2,281), the provision of locks and safes (864), detective services (767) and bailiff services (440).In the case of Britain, for example, the estimation of private security employees (70,000) appears to include only those working for member companies of the British Security Industry Association, the main trade body. On the basis of these figures, Britain ranks sixth in terms of private security employees (123 per 100,000 inhabitants) and has a private security to public poli ce ratio of 0. 39:1. By using Jones & Newburn’s (1998) data, however, these estimates are transformed dramatically.This happens whether one bases calculation on guard numbers alone, or upon the total number of personnel employed in the security industry. In the first case, the figure of 182,596 guards identified in the research generates 321 security personnel per 100,000 inhabitants and a private security to public police ratio of 1:1. In the second case, 333,631 security employees generates a private security to public police ratio of 1. 85:1, a figure far in excess of the estimate for Germany, the highest ranked country in the sample.In effect, two conclusions can be drawn from Jones & Newburn’s (1998) research: that Britain has roughly one private security guard for every public police officer, a figure comparable to that found in the USA during the early 1980s (Cunningham & Taylor 1985:106); and that Britain has almost two private security employees for each polic e officer. Although there are diverse estimates of the number of organizations trading in the private security sector, and the numbers of people working, few of them emerge to be reliable.The best accessible figures suggest that, in broad terms, the number of private security employees, including those persons concerned in the manufacture and installation of security devices, is as a minimum the equivalent of the total complement of the forty-three constabularies in England and Wales; data from the government's Labour Force Survey propose that there are almost surely over 162,000 people working in the private security industry, but the actual total can be at least half as many again (Jones T. , and Newburn T. 1995).This rapid growth in private security gives a vivid image that policing involves much more than the police and what the police do. The point is made all the more obvious if one thinks that most symbolic of all police tasks, mobile patrol. It is momentarily worth consideri ng two instances where a ‘police patrol' presence is provided by personnel other than police constables. First is the Sedgefield Community Force. For several years local councils have employed in-house security operations to keep council property and employees.The Sedgefield Community Force, a local authority police force in County Durham, became operational in January 1994. The force provides a 24-hour patrolling service within the geographical confines of the District an area of 85 square miles and a population of 90,000 people. The ten patrol officers wear uniforms similar to those worn by police officers. They travel mostly in cars, though they are encouraged to leave them to patrol on foot. They received 1,284 calls from the public in their first year.Johsnton (1999) asserts that Private policing resolves the tension within that relationship: maximizing consumption by restricting access to those who might undermine the commercial imperative—drunks, beggars and the like. In most western societies—though particularly in North America—there is an increased tendency for residential space to adopt the form of mass private property, people living in private apartment blocks and gated communities, rather than in traditional streets.Though this is undoubtedly a global tendency, however, there may be variations in the speed and scope of its development. Jones & Newburn (1998) note that, in Britain, locations which would be archetypal forms of mass private property in North America (such as educational institutions, leisure complexes and hospital sites) have either been owned and run by the state or by non-market ‘hybrid’ organizations (Johnston 1992). For that reason, they suggest, ‘mass hybrid property’, rather than mass private property, may be of greater relevance to the future development of commercial policing in Britain.Though the Sedgefield Community Force provides a noticeable patrol it was set up as a n on-confrontational force and has a strategy of ‘observing and reporting' based on a presupposition of not using officers' citizen's powers of arrest. A small-scale piece of research on the Sedgefield Community Force carried out concerning six months after it was set up found that just under two-thirds of local residents said without any prompting that they had heard of the Force (I'Anson J. , and Wiles P. 1995).This part of respondents increased to three-quarters after the force was portrayed to them. There is some indication from the survey that the public feels safer as the Force was introduced, and a considerable proportion of those questioned felt that the Community Force would act to put off criminal activity. There was obvious evidence that local residents saw the Force as setting off what the local constabulary was doing.Generally respondents said they would not be happy to have the members of the Force as the sole deferrers of crime. owever when asked who they would be contented to have patrolling their streets: 91 per cent said police specials or a new rank of police patroller; 83 per cent said a council-employed community force; 43 per cent said common citizens; and 33 per cent said private security guards. A further survey of residents who had asked for help from the Sedgefield Force discovered that the immense majority of calls concerned vandalism, anti-social behavior, and nuisance — incivilities concerning which all the research evidence shows the public is usually concerned though a large minority, about a fifth, concerned straight-forward crime (Wiles P. 996).Moreover those persons calling for help were extremely appreciative of the service they received. Though direct comparisons cannot simply be made, the residents who call the Sedgefield Community Force are as a minimum as appreciative of the service they receive, conceivably more so, than are people who call the police (Bucke, 1996). The second example is the Wands worth Parks Constabulary. Under the Public Health (Amendment) Act 1907, all local authorities in England and Wales can affirm in park employees as special constables though there are few instances of any doing so.Legislation, bearing upon London only, has though been used by several boroughs in the capital to set up Parks Constabularies. in the Ministry of Housing and Local Government Provisional Order Confirmation (Greater London Parks and Open Spaces) Act 1967, Wands worth recognized its Parks Constabulary in 1985. There are thirty full-time uniformed officers and twenty-five part-timers (effectively ‘specials') in the Wands worth Parks Constabulary.They patrol the parks and open spaces in the borough — about 850 acres in all — and give security services in council premises, particularly the branch libraries, leisure centers, and youth and recreation facilities. The constables aim to act mainly as a restriction rather than an enforcement body. The problems with which they deal emerge to be similar to those dealt with in Sedgefield. They comprise incivilities linked with drunkenness, the control of dogs, the use of bicycles, and the like. however they also deal with crime.In 1994 and 1995 the Wands worth Parks Police made 105 and 134 arrests correspondingly: these included supposed offences of dishonesty (including burglary, theft, and robbery), criminal damage, gross coarseness, and drugs offences. They took their arrestees to Metropolitan Police stations where there appears to have been little complexity in getting the majority of their charges accepted. Certainly the research proof is that the relationship between the Parks Police and the Metropolitan Police is an optimistic and close one (Jones T. , and Newburn T. 998).In addition the constables monitor the CCTV cameras that are positioned in Wandsworth's parks, act as key holders in relation to a large number of local power buildings, provide a cash-in transit service for some local authority fun ctions, and accompany some local authority employees. Similar, although generally less wide-ranging, parks police also operate in Kensington and Chelsea, Barking and Dagenham and in Greenwich. The public is ever more engaged in activities in areas where policing is undertaken by private organizations.Progressively households, neighborhoods, and institutions (both public and private) are becoming dependent on commercially provided surveillance technology and patrols for their sense of security. As, demands on the police have prolonged, so the police have become reliant on skills available in, and services provided by, the private sector. This is mainly to be welcomed, and positive collaboration between the public and private sectors needs to be encouraged.There are several benefits to be gained from constructive partnership. But it is fundamental that this partnership be based on integrity. The public, pass up the police, must have confidence that the very highest standards are being uphold in any agency with which the police are affianced in partnership. For these reasons we conclude that the time has come to bring in a system of official or statutory directive of the private security industry.There is no case for granting private security personnel powers not accessible to the ordinary citizen and, as far as it is been competent to discover, there is no demand from either within or without the industry that such powers must be granted, except in very particular situation. One such circumstance is given by the contracted-out management of prisons. The Criminal Justice Act gives that the prisoner custody officers employed by the security companies now running five prisons are authorized to search prisoners and their visitors and to use such force as is essential to avert prisoners from escaping.But this kind of exception apart we can see no motive why citizens' powers are insufficient for dealing with the type of situations with which private security personnel are expected to be confronted while guarding or on patrol. Indeed, quite opposing. The fact that security personnel have no powers beyond those accessible to the ordinary citizen itself gives a desirable check on their activities and evidently demarcates, both in law and in the eyes of the public in general, what is otherwise becoming an increasingly fuzzy border between the police and private ‘policing' enterprises.The realism of private security is that their personnel are not like usual citizens. They may not have extra powers, but they have precise responsibilities, they are organized, they are usually recruited as of their physical suitability, they are dressed in a way to emphasize their capacity to coerce, they might be trained in self-defense or have experience in how to ‘handle themselves' in circumstances thought to rationalize reasonable force, they are more expected to employ force, and so on.All these influencing conditions suggest, given the extensive conc erns ‘about the de facto power exerted by private security personnel whose reliability is uncertain, whose public liability is non-existent, and whose allegiance is by definition to whomsoever pays the piper, that there is a very well-built case for ensuring that in law they exercise no more right to use force than the rest of us. We conclude that no transform in citizens' powers of arrest is reasonable.The key area, is where private security staff are concerned in the policing of space which is public -streets, housing estates, and so on — or which the public thinks to be public, although it is actually private, that is places like shopping malls, football grounds, hospitals, and so on. We believe any new form of regulation must certainly cover the work of private security guards, together with contract and in-house guards. The Home Affairs Select Committee excluded in-house staff from its commendations for regulation.However, though the evidence signifies that there a re fewer complaints concerning in house security services, the fact that there is considerable mobility between the contract and the in-house sectors leads us to believe that any new system of licensing must cover both. Moreover, given their role concerning either private property or private space to which the public have access, equally nightclub door staff and installers of electronic surveillance and security equipment ought, in our finding, also to come within a new system of directive.
