The Greatest Literary Ideas John Keats - 1860 Words

John Keats presented one of the greatest literary ideas, negative capability, in the most casual way possible – a few loose lines in a personal letter to his brothers in 1817: â€Å"The excellence of every art is its intensity, capable of making all disagreeable evaporate, from their being in close relationship with beauty and truth†¦I had not dispute but a disquisition with Dilke, on various subjects. Several things dovetailed in my mind, and at once it struck me what quality went to form a man of achievement, especially in literature, and which Shakespeare possessed so enormously. I mean negative capability; that is, when man is capable of being in uncertainties, mysteries, doubts, without any irritable reaching after fact and reason. Coleridge, for instance, would let go by a fine isolated verisimilitude caught from penetralium of mystery, from being incapable of remaining content with half-knowledge. This pursued through volumes would perhaps take us no further than this: that with a great poet the sense of beauty overcomes every other consideration, or rather obliterates all consideration.† A poet’s capability of being negative is in a sense of being able to resist the instinct of seeking concrete certitude and closure and being able to accept the full-extended experience that poems aim to capture is no way to be theorized or simplified by words or stanzas. Being negatively capable requires a poet to give up the rational pursuit of conceptualizing complex experienceShow MoreRelatedJohn Keats Elusive Concept Of Negative Capabilities 943 Words   |  4 Pagesnumerous problems one encounters when attempting to study John Keats’ elusive concept of ‘negative capability’. There has been endless scholastic studies done on the topic, which have resulted in almost as many interpretation of the concept as there are studies.

What is a sports physical therapist? A sports physical therapist is a physical therapist who specializes in the field of sports medicine.

How to Continue your Research with a PhD Free Essays

So, you’ve handed in your dissertation, and all has gone well. You’re on track to get a good grade, and are interested in taking things further. This guide looks at how to continue your research with a PhD, from deciding whether a PhD is really right for you to the process of applying to start one. We will write a custom essay sample on How to Continue your Research with a PhD? or any similar topic only for you Order Now Is a PhD right for you? You need to be very certain that doing a PhD is the right step for you to take, as the road is long and arduous, and often lonely. Be very honest about your motivations. Ask yourself: what am I hoping to get from doing a PhDAre there other options which are possible for meAm I really sure what doing a PhD will involveAm I thinking about this because I don’t want to do something else (for example, not wanting to get a job, or not sure what career path to take). Talk to other people who have done, or who are doing, a PhD. What are the negatives, the positivesAre there any things they didn’t expect Remember the time frames: a typical PhD in the UK takes 3-4 years full time, 5-7 years part time. You need to be very motivated and able to work under your own direction. You also need to be really interested in the area you plan to research. If you enjoyed the element of independent research during your dissertation, you might well be right for a PhD If you want to go into academia you will probably need a PhD. What Skills do I need to do a PhD? To a large extent, the skills you need for doing a PhD are the skills you needed to complete your dissertation. But make sure you are adept at the following: Critical thinking – the ability to analyse and critique the evidence. It’s no longer enough to describe and organise. Communication, presentation and writing – you will be spending a lot of time preparing information for other people. By the end of your PhD you will be able to produce work of a publishable quality, and communicate with different audiences (primarily in writing, but also in person) Planning and management – conducting your research is rather like managing a small office. You need to know how to plan, how to delegate, how to deal with people. You need to be able to plan and manage both at the micro and the macro level. Networking – although much of the time you spend writing your PhD will be time spent alone, you also need to get on well with people in order to get feedback, make contacts, initiate new projects. Initiative – you need to be able to think for yourself How to Apply for a PhD Unlike applying for an undergraduate course, there is no single application point for PhDs. Rather you need to apply directly to the university you are interested in It pays to do your research at this stage – don’t assume that you should stay at the university you did your master’s degree at. You should consider narrowing down your search to a few universities who do work in your area of interest, and then ask to visit to discuss your ideas with them. You can find a lot of useful information on university websites regarding staff interests. Funding your PhD You do need to consider the financial aspect. While funding exists for PhDs, many research students are self-funded. In this case, unless you are independently wealthy, part-time study might be the best option for you. You will also find funding opportunities advertised online on university websites, as well as in specialist publications. Some advertised PhD studentships come with funding, so if you succeed in your application to such a studentship (and if you are eligible) you will also get funding Bibliography Prospects.ac.uk (2013) ‘Postgraduate qualifications: PhDs’, [online] (cited 5th March 2013) available from http://www.prospects.ac.uk/postgraduate_qualifications_doctorates.htm University of Bristol (2013) ‘Aims, Objectives and Guidelines for PhD students’, [online] (cited 5th March 2013) available from http://www.cs.bris.ac.uk/Teaching/learning/phd-guidelines.html University of Edinburgh (2013) ‘Moving on to a PhD’, [online] (cited 5th March 2013) available from http://www.ed.ac.uk/schools-departments/careers/postgrad/research-masters/moving-onto-phd How to cite How to Continue your Research with a PhD?, Essays

What Is Windows Server Essay Example For Students

What Is Windows Server? Essay Project 1 Phillip Foster What is Windows Server? Windows Server 2008 is one of Microsoft Windows server line of operating systems. Released to manufacturing on February 4, 2008, and officially released on February 27, 2008, it is the successor to Windows Server 2003, released nearly five years earlier. A second release, named Windows Server 2008 R2, was released to manufacturing on July 22, 2009. Like Windows Vista and Windows 7, Windows Server 2008 was built on Windows NT 6. x. Windows Server 2008 R2 Foundation is a cost-effective, entry-level technology foundation targeted at small business owners and IT generalists supporting small businesses. Windows Server 2008 was built from the same code base as Windows Vista; therefore, it shares much of the same architecture and functionality. Since the code base is common, it automatically comes with most of the technical, security, management and administrative features new to Windows Vista such as the rewritten networking stack, native IPv6, native wireless, speed and security improvements; improved image-based installation, deployment and recovery; improved diagnostics, monitoring, event logging and reporting tools; new security features such as BitLocker and ASLR; improved Windows Firewall with secure default configuration; . NET Framework 3. technologies, specifically Windows Communication Foundation, Microsoft Message Queuing and Windows Workflow Foundation; and the core kernel, memory and file system improvements. Processors and memory devices are modelled as Plug and Play devices, to allow hot plugging of these devices. This allows the system resources to be partitioned dynamically using Dynamic Hardware Partitioning; each partition has its own memory, processor and I/O host bridge devices independent of other par titions What are the different editions of Windows Server? Windows Server 2008 R2 Standard is the most robust Windows Server operating system to date. With built-in, enhanced Web and virtualization capabilities, it is designed to increase the reliability and flexibility of your server infrastructure while helping save time and reduce costs. Windows Server 2008 R2 Enterprise is an advanced server platform that provides more cost-effective and reliable support for mission-critical workloads. Windows Web Server 2008 R2 is a powerful Web application and services platform. Featuring Internet Information Services (IIS) 7. and designed exclusively as an Internet-facing server, it offers improved administration and diagnostic tools to help reduce infrastructure costs when used with a variety of popular development platforms. With included Web Server and DNS Server roles, as well as improved reliability and scalability, this platform allows you to manage the most demanding environments — from a dedicated Web server to an entire Web server farm . Windows HPC Server 2008, the next generation of high-performance computing (HPC), provides enterprise-class tools for a highly productive HPC environment. Windows HPC Server 2008 can efficiently scale to thousands of processing cores and includes management consoles that help you to proactively monitor and maintain system health and stability. Windows Server 2008 R2 for Itanium-Based Systems delivers an enterprise-class platform for deploying business-critical applications. Scale database, line-of-business, and custom applications to meet growing business needs. Help improve availability with failover clustering and dynamic hardware partitioning capabilities. Virtualized deployments with rights to run an unlimited number of virtual instances of Windows Server. What are the limitations of the various editions? Physical Memory Limits: Windows Server  2008  R2 in 64-bit; Windows Server  2008  R2 Datacenter 2TB Windows Server  2008  R2 Enterprise 2TB Windows Server  2008  R2 for Itanium-Based Systems 2TB Windows Server  2008  R2 Foundation 8TB Windows Server  2008  R2 Standard 32TB Windows HPC Server 2008 R2 128TB Windows Web Server 2008 R2 32TB Processor Windows Web Server 2008 R2 1  GHz (x86) or 1. 4  GHz (x64) (x64 required for R2) 2  GB RAM or higher Maximum (32-bit systems): 4  GB RAM (Standard) or 64  GB RAM (Enterprise, Datacenter) * Maximum (64-bit systems): 8  GB (Foundation) or 32  GB RAM (Standard) or 2  TB RAM (Enterprise, Datacenter and Itanium-Based Systems) * 30   GB or higher disk space * Computers with more than 16  GB of RAM require more disk space for paging and dump files. What a re the advantages / disadvantages of using Windows Server versus other server operating systems – such as UNIX or Linux? Stability: UNIX systems (we actually use Linux but for comparison purposes, they are identical) are hands-down the winner in this category. .ud435d67b4b6aea28ba33287fbd241d77 , .ud435d67b4b6aea28ba33287fbd241d77 .postImageUrl , .ud435d67b4b6aea28ba33287fbd241d77 .centered-text-area { min-height: 80px; position: relative; } .ud435d67b4b6aea28ba33287fbd241d77 , .ud435d67b4b6aea28ba33287fbd241d77:hover , .ud435d67b4b6aea28ba33287fbd241d77:visited , .ud435d67b4b6aea28ba33287fbd241d77:active { border:0!important; } .ud435d67b4b6aea28ba33287fbd241d77 .clearfix:after { content: ""; display: table; clear: both; } .ud435d67b4b6aea28ba33287fbd241d77 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ud435d67b4b6aea28ba33287fbd241d77:active , .ud435d67b4b6aea28ba33287fbd241d77:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ud435d67b4b6aea28ba33287fbd241d77 .centered-text-area { width: 100%; position: relative ; } .ud435d67b4b6aea28ba33287fbd241d77 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ud435d67b4b6aea28ba33287fbd241d77 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ud435d67b4b6aea28ba33287fbd241d77 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ud435d67b4b6aea28ba33287fbd241d77:hover .ctaButton { background-color: #34495E!important; } .ud435d67b4b6aea28ba33287fbd241d77 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ud435d67b4b6aea28ba33287fbd241d77 .ud435d67b4b6aea28ba33287fbd241d77-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ud435d67b4b6aea28ba33287fbd241d77:after { content: ""; display: block; clear: both; } READ: Why I Choose Culinary Arts EssayThere are many factors here but to name just a couple big ones: in our experience, UNIX handles high server loads better than Windows and UNIX machines seldom require reboots while Windows constantly needs them. Servers running on UNIX enjoy extremely high up time and high availability/reliability. Performance: While there is some debate about which operating system performs better, in our experience both perform comparably in low-stress conditions however, UNIX servers under high load (which is what is important) are superior to Windows. Scalability: Web sites usually change over time. They start off small and grow as the needs of the person or organization running them grow. While both platforms can often adapt to your growing needs, Windows hosting is more easily made compatible with UNIX-based programming features like PHP and MySQL. UNIX-based web software is not always 100% compatible with Microsoft technologies like . NET and VB development. Therefore, if you wish to use these, you should choose Windows web hosting. What is Active Directory and how is it used? Active Directory provides the means to manage the identities and relationships that make up your organizations network. Integrated with Windows Server 2008 R2, Active Directory gives you out-of-the-box functionality needed to centrally configure and administer system, user, and application settings. Active Directory Domain Services (AD DS) stores directory data and manages communication between users and domains, including user logon processes, authentication, and directory searches. An Active Directory domain controller is a server that is running AD DS What are the benefits of utilizing Active Directory?

Ozone Depletion The ozone layer is the earth’s protection against harmful ultra-violet rays that cause cancer. The ozone is a region of the earth’s atmosphere that is 12 to 30 mi above the earth’s surface. (www.encarta.msn.com) The layer of the Earth's atmosphere that surrounds us is called the troposphere. The stratosphere, the next higher layer, extends about 10–50 kilometers above the Earth's surface. Stratospheric ozone is a naturally occurring gas that filters the sun's ultraviolet (UV) radiation. (www.factmonster.com) The ozone’s job is to absorb much of the radiation that the sun gives off. There are two forms of this radiation that come from the sun: visible light and ultra-violet light. Visible light waves are the only electromagnetic waves we can see with are eyes and ultra-violet light is the radiation that humans have to protect themselves against. (http://imagers.gsfc.nasa.gov) Humans on earth are destroying the very thing that protects us and allow us to continue to live on this earth. Without our ozone all human and living things on this earth will seize to existence. To protect our home we need to evaluate the causes, the effects and the future of ozone depletion. The Cause What is the cause of our depleting ozone? It is believe to be caused by many of the things we used in our everyday lives: cars, refrigerators and aerosol cans. The ingredients that are in these items are compounds called chlorofluorocarbons (CFC), which was created in 1928 and other pollutes like halons that are used in fire extinguishers. (www.factmonster.com) When CFCs reach the stratosphere, the ultraviolet radiation from the sun causes them to break apart and release chlorine atoms, which react with ozone, starting chemical cycles of ozone destruction that deplete the ozone layer. One chlorine atom can break apart more than 100,000 ozone molecules. (www.greenpeace.org) Chlorofluorocarbons and these other polluta...

Ancient and Medieval Political Theory Assignment

Ancient and Medieval Political Theory - Assignment Example Aquinas in the theory hypothesized the concept of nature to help society members understand that there is a supernatural being beyond this earth. Aquinas further argues that the world is merely a resting bay after which humans move to another life. This concept outstands in the Thebes society when various characters keep invoking the punishment sinners will receive from gods after death. Creon’s wife, Eurydice commits suicide cursing the husband and expressing her wish for god’s punishment upon the death of the husband. The blind prophet Tiresias brings the supernatural concept by claiming prophesies of god’s desires and anger to the king. The concepts solve the conflict between the church and the human freedom to think. It shows that the actions of the worldly authority must reconcile with the wishes of the church for harmonious coexistence. The concept of sovereignty is the source of law. Based on political ideologies and tenets, sovereignty rests with the people’s power. Based on theological points of view, however, sovereignty originates from God. It, therefore, gives individuals the freedom to make decisions without autocracy from rulers and the church. The concept of supremacy of the church also creates harmony between the church and the government. Creon, the dictator who does not obey the will of his people, chorus later comes to lament when his son Haemon and wife commits suicide for his actions. Disobedience of sovereignty attracts heavy punishment from God irrespective of who you are in the

Wireless Security - Research Paper Example On the other hand, there are countless security and privacy issues also emerging in wireless networking environments. Though, the new technologies require more and more high level application of wireless communication networks, but such implementations are being established without giving significant concentration to privacy and security related issues. Consequently, the majority of wireless networks around the world are in danger regarding security and safety. Thus, there are a lot of chances that someone with appropriate equipment could be able to spy network traffic. In this scenario, they can get access to users’ passwords and other data (Gerkis, 2006; The State University of New Jersey, 2006). In addition, these security issues and attacks are not immediately theoretical. Additionally, techniques and tools to tap near wireless networks are extensively accessible, even for palmtop devices (Gerkis, 2006; The State University of New Jersey, 2006). In this situation there is vital need for implementing wireless security. Wireless security management has turned out to be a hot issue in literature. This paper presents a detailed analysis of wireless security related issues and their management. This research will analyze some of the important aspects of wireless security, main challenges and possible mitigation techniques. TECHNOLOGY INVOLVED IN WIRELESS NETWORKS Consider the fact that users of WLAN (wireless local area network) are able to travel along with their laptop computers and other devices from one location to another inside their offices or houses without breaking the link with the network. Thus, many corporations and general public at the present think that wireless communication based devices are very useful, efficient, and easy to operate. On the other hand, personal networks based on wireless technology help users receive and distribute data, as well as software applications, by making use of network systems and other users of the network with well-matched devices, without establishing a connection to printer cables and other secondary device links. In fact, with wireless networking users of small PDA, hand-held devices and cell phones can effectively coordinate data and information among PDAs and personal computers, as well as are able to effectively make use of internet based services l ike that web browsing, email and internet access. In addition, wireless communications can help individuals and business firms reduce their networking or wiring costs (Radack, 2011; Gerkis, 2006; css-security, 2010). In this scenario, Information Technology Laboratory established by NIST (National Institute of Standards and Technology), presents various standards and measures which can be adopted to enhance safety and security of wireless communication networks. Additionally, National Institute of Standards and Technology Special Publication (SP) 800-48,  Wireless Network Security, 802.11, Bluetooth, and Hand-held Devices, whose authors were Les Owens and Tom Karygiannis, outlines 3 main and fundamental aspects of wireless security: (Radack, 2011; Ge

Cell Migration And Cell Cytoskeleton Biology Essay

Cell Migration And Cell Cytoskeleton Biology Essay The cytoskeleton of a cell plays a vital role in controlling the movements of the cell. 3 types of fibres form this structure; microtubules, microfilaments and intermediate filaments. Microtubules are large hollow fibres, microfilaments are the smallest at only 6nm in diameter (1) and intermediate filaments are in between. Microtubules are formed from the subunits ÃŽ ± tubulin and ÃŽ ² tubulin, which form dimers. Each tubulin dimer contains 1 ÃŽ ± tubulin subunit and 1 ÃŽ ² tubulin subunit. These then polymerise to form long protofilaments, which join together into sheets. Once a sheet of 13 protofilaments has been formed, they then fold over to produce a hollow microtubule, which continues to elongate from the +ve end where only ÃŽ ² tubulin subunits are showing. Microfilaments are made of a protein subunit called actin. There are two types; G actin and F actin. G actin is turned in to F actin by the hydrolysis of ATP, forming a fibrous filament. The actin filament continues to elongate from the -ve barbed end. There are several types of Intermediate filaments, each made of different proteins depending on the function of the cell in which they are contained. Type I Keratins acidic and Type II Keratins basic are found in epithelial cells and in the hair and nails. Nuclear lamins are found in the nuclear lamina and type III vimentin/desmin/peripherin are found in muscle cells, some neurones and stem cells (2). The monomers form dimers by coiling. Tetramers are then formed from dimers arranged in staggered formation with opposite domains together. These then arrange together forming strong coiled filaments. Many cells move by crawling over surfaces (3). Of the three fibrous structures, explained previously that make up a cell, the microfilaments play the largest part in the movement and migration of a cell. This means that actin is the vital component for cell movement. A fibroblast crawls by a leading protrusion, called a lamellipodium, which is where most of the cells actin is located. The actin is extremely flexible due its twisted, linked structure. The filaments clump / bundle together near the cell membrane, particularly at the protrusions such as the microvilli in an intestine lining epithelial cell. The actin penetrates in to the cytoplasm, where they become cross linked in to a three dimensional meshwork, governing the shape and mechanical properties of the plasma membrane and the cell surface. (4) . This means that the actin provides structural support, as well as movement potential for the cell. Filopodia are very similar to lamellipodia. They also protrude out from the mai n body of the cells like lamellipodia, and act like fingers for the cell to feel the environment around it and also to aid the detection of where the cell is supposed to migrate to. Filopodia have almost the exact same structure as lemellipodia, however have smaller protrusions and therefore contain less actin. They are about 0.1 Â µm wide and between 5 10 Â µm long, and each contains a loose bundle of 10 20 actin filaments, orientated with their positive ends pointing outward'(5), exactly like the orientation of the actin filaments in lamellipodia. However, filopodia are present around the whole circumference of the cell, not just protruding from the lamellipodium, which creates an even larger surface area for the cell to detect its surroundings. The protrusions grow by the growth of the actin filaments, where dimers are added to the positive terminals of the filaments. Although dimers are removed from both terminals, particularly the negative end, this is outweighed by the mor e rapid addition of actin at the positive end. The growth is a very quick process, which therefore allows the cells to move around the body at a fairly fast pace. Once the lamellipodium is protruded from the main structural shape of the cell, the newly produced bottom section of the cell then adheres to the surface it is moving along, hence pulling the rest of the cell along with it. At the same time, contraction occurs at the rear of the cell, then draws the body of the cell forward, in the direction the lamellipodium is protruding, in a process called traction. (6) Cell migration is extremely important to an organisms survival. It is essential for the movement of cells in the immune system, an example of which is a macrophage, which finds destructive cells and eats them. This is because it is vital for cells to be able to travel to the site of an infection in order to fight it and clear it up or to communicate with other cells, to let them know that there is a problem, which they can then sort out. Cells that can do this are called fibroblasts, which migrate through connective tissue, remodelling them where necessary and helping to rebuild damaged structures. (7). If this was not possible, the organism would be in serious trouble and could die or be badly damaged by very superficial wounds and mild diseases which are overlooked as non-serious in humans due to cells being able to migrate. The cell migration mechanism is vital to a macrophage, as its job is to move around the body, detecting and destroying harmful cells. If movement was not possi ble, the macrophage would only be able to detect destructive cells that were situated in the immediate vicinity, which means to successfully remove all harmful pathogens would be impossible. This would mean the organism would have very little protection against disease. Cells are also able to migrate by means other than by lamellipodium protrusions. Cilia are one example, as well as a male humans sperm, which moves by a tail like structure called a flagellum. The sperm is able to beat the flagellum, which is designed to move the entire cell, and instead of generating a current, they propagate regular waves along their length that propel and drive the cell through liquid (8). Unlike most other migrating cells in the human body as described above, the main component for movement in flagella is tubulin. Microtubules span the whole length of the flagellum in an axoneme, which contains two central microtubules that are surrounded by an outer ring of nine pairs of microtubules. (9). The movement is enabled by molecules of ciliary dyenin that form bridges between neighbouring microtubules around the circumference of the axoneme. (10) The end tail of one molecule attaches to a microtubule, while its other end, the head of the molecule attaches to another m icrotubule. This promotes a sliding mechanism similar to that of actin in the migration of cells with lamellipodium protrusions. Bacteria and cilia also have flagella, made of flagellin and dynein. The bacterial flagellum has a similar structure to a microtubule in the way that it is a hollow, tube like shape. Ciliary beating can either propel single cells through a fluid or can move fluid over the surface of a group of cells in a tissue (11). The second is apparent in the human respiratory system, where ciliated respiratory epithelium cells in the trachea prevent any foreign, potentially harmful particles such as dust and bacteria in the air from entering the bronchioles and lungs. They do this by acting like tiny hairs and by beating the saliva containing the harmful particles back up the trachea to exit the nasal cavities by coughing. If the cilia are unable to beat, it causes problems such as Kartageners syndrome or primary ciliary dyskinesia. Although this syndrome is extremely rare, it is a genetic disorder, meaning it is hereditary. Due to the respiratory system having little to no defence against dust and pathogens which enter the nasal cavities and then travel down the trachea and bronchi, harmful particles may enter the lungs. This causes infection and disease of the lungs, such as pneumonia or bronchitis. In conclusion, the presence of cell migration mechanisms in organisms as small as bacteria to the large, multi cellular organisms such as humans is extremely vital to their individual survival. Without such an important ability, cells would not be able to detect or fight disease, from minor superficial impediments to very serious illnesses. Reproduction in humans would not be possible and bacteria would find it extremely difficult to invade host cells for reproduction. Without cell migration, the whole human immune system would not be able to function correctly. Although the movement of cells is quite complex, it is only the beginning of a massive sequence of mechanisms in which cells can communicate with each other to orchestrate the correct workings of the human body.

The Changing Role of Human Resources :: Human Resources Essays

Introduction In most companies today, the HR function provides vital services to such stakeholders as job applicants, workers, supervisors, middle managers, and executives. Yet, the HR function tends to be located at the end of the business chain, on the reactive side, and too frequently centers on carrying out actions rather than achieving outcomes. The role of the HR function is frequently one of providing people, training, and secluded HR efforts after others have formulated organizational strategy and have initiated operational accomplishment. Cost centered management of worker benefits programs such as health insurance, workers' compensation, and pension plans have also figure outstandingly in an effort to control out of control operating costs (Dunn, 2006). Discussion The HRM department at our company does not really play a strategic role in the organization. Presently they spend the majority of their time doing the day to day things like hiring people, training, and other HR efforts that allow the business to function everyday. In order for business to achieve success in the every changing business world it is important for HR departments to become more strategically aligned with the overall goals and efforts of companies. There are three key reasons why businesses are changing their methods. The first is reducing costs. HR departments should no longer want to be seen as just a support function and cost center, they need to show their value. Secondly, it is the competitiveness of business today and the fight to employ and retain people that will help drive the business. Finally, HR departments are now expected to have an understanding of how other departments function in order to make a valuable contribution to the whole of the business (Brockway, 2007). The HR professional who will succeed in guiding their organizations into the future will be those who understand and use business strategy; understand corporate culture, plans and policies; recognize future problems and work solutions; can deal with all types of people; can communicate well verbally and in writing; and can recognize, recruit and train future executives. As organizations continue to move towards collective systems and combined financial resources for managing their human capital, we are likely to see more organizational structures combining both HR and Organizational Development (OD). The time has come to quit debating OD's involvement in HR systems and seek the present opportunities of showcasing the skills of OD in building organizational capacity and having a measurable impact on workforce productivity.
