Douglass and Whitman Race and Racism Relations - Free Essay Example

Sample details Pages: 2 Words: 570 Downloads: 5 Date added: 2019/02/05 Category Society Essay Level High school Tags: Racism Essay Did you like this example? Racist and racism are evocative words of a reality that cannot be denied. One of the renowned writers in English literature has given us some solutions to this contemporary problem. Walt Whitman has commonly been professed as one of the few white American writers who excelled the racial attitudes of his time, a great prophet rejoicing the cultural and racial multiplicity and embodying democratic ideals. Don’t waste time! Our writers will create an original "Douglass and Whitman Race and Racism Relations" essay for you Create order When I think about Walt Whitman the first thing that comes to my mind is a big part of his poetic philosophy is kind of have a free spirit and treating everyone equally. He is against slavery at the time and against about racism. Even though he had his struggles of being gay at a time when people take that as the end of the world. Comparatively even five to ten years ago people in America had a concept that being homosexual is not the end of the world. But in his time slavery and being homosexual exiles were the same thing and you could be killed or be in prison. But it gives Whitman in his poetry the view of what his ‘his’ person if everyone knew he would be condemned as well. So, he had to live with that. That is why Whitman is considered as the first epic American poet who believes that we should treat each other equal. Frederick Douglass’s writing has also given us the viewpoint about racial judgment remains and which were a substantial problem back then, this must be understood against the contextual of extraordinary progress since decades. And the fact of the matter is that there is mostly no practicable alternative to some form of favorable action if we want to pledge the evil effects of certain forms of insight. Thus, although Whitman’s racist opinions of blacks, shaped in part by the bad science of the day, were inconsistent and at times unsure, his poetic vision stimulated a way past his own conventional limitations toward better justice. His solution to the inconsistency was to avoid racial subjects, much as he would avoid issues about the massacre being committed against Native Americans. He could not even resolve such inconsistencies in his own spirit. Therefore, the first thing I consider as I explore this is the reality that Americans don’t really believe America dar n aware of. In the same way, Douglass was writing for people who are not used to hearing this. He is talking to people through his writing only look at other Americans misconception of slavery today and American slavery was a part of the worldwide system. but by focusing on it he was writing for people who can only think of black people as ‘slaves’ that’s all they can be and that is what civil war was about. People of north say that as human being we can’t deal with the slavery anymore. And then Douglass is coming in and saying why don’t I write and speak to everyone through my writing. As a result, both writers grab the attention of people who would not normally pay them any mind. As we can see for both sides of this issue that people voted is one of the most stressful if we added the likes of Douglass and Whitman into this dialogue and calm people for a second and brought intelligent wisdom into this that might solve a lot of problems.

Investment Management - 13738 Words

1 INVESTMENT MANAGEMENT Note: These course notes were written by Professor Virginia Maracine PhD and Professor Emil Scarlat PhD Department of Economic Cybernetics, Academy of Economic Studies Bucharest, using the announced references (see the Course s Syllabus). Chapter 1 Introduction. Basic of Investment 1.1. What Investment it is about? But Investment Management? 1. Investment - concepts and types The word Investment originates in the Latin vestis, meaning garment, and refers to the act of putting things (money or other claims to resources) into others pockets. The basic meaning of the term being an asset held to have some recurring or capital gains. It is an asset that is expected to give returns without any work on the†¦show more content†¦Thus investment is everything that remains of production after consumption, government spending, and exports are subtracted. I is divided into non-residential investment (such as factories) and residential investment (new houses). Net investment deducts depreciation from gross investment. It is the value of the net increase in the capital stock per year. Investment, as production over a period of time (per year), is not capital. The time dimension of investment makes it a flow. By contrast, capital is a stock, that is, an accumulation measurable at a point in time (say December 31st). Investment is often modeled as a function of Income and Interest rates, given by the relation I = f(Y, r). An increase in income encourages higher investment, whereas a higher interest rate may discourage investment as it becomes more costly to borrow money. Even if a firm chooses to use its own funds in an investment, the interest rate represents an opportunity cost of investing those funds rather than loaning them out for interest. Finance Approach In finance, investment = cost of capital, like buying securities or other monetary or paper (financial) assets in the money markets or capital markets, or in fairly liquid real assets, such as gold, realShow MoreRelatedInvestment Management Case Study1305 Words   |  6 PagesBeta Management Company | | |Investment Management case study | Table of contents Backgrounds†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.†¦Ã¢â‚¬ ¦1 Strategies†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦...1 Background of California R.E.I.T and Brown Group Inc†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦2 Return and risk†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.....†¦2 Summary†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦...4 Appendix†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦...5 Background: BetaRead MoreInvestment Analysis Portfolio Management1583 Words   |  7 PagesHere is the term paper on investment analysis portfolio management from 31st may to 1st august.

Digital Identity and Access

Question: What trust relationship must be configured to secure trust relationships that makes users digital identity and access rights available to trusted sites? Answer: A federation trust is required to accomplish this. Once a federation trust is created between two organizations, one organization plays the role of the account partner organization while the other of the resource partner organization, wherein users of the former can send authorization requests through the federation trust to the latter. An AD FS-enabled web server should be present at the Resource Partner Organization. How to use Windows Integrated Authentication and strong authentication technologies. For authentication to Active Directory domain services, Kerberos version 5 authentication protocol is used along with extensions for public key authentication. The Kerberos authentication client is available via the Secure Support Provide Interface (SSPI) as a Security Support Provider (SSP), and is in turn integrated with Winlogon single sign-on architecture; whereas the Kerberos Key Distribution Center works in integration with other Windows Server security services. How to use Lightweight Directory Access Protocol (LDAP) binding to authenticate users. The authorization state unauthenticated is allotted by default when a client connects to LDAP directory server for the first time. An LDAP client is used to transmit a BIND request to the server which changes the connection state to authenticated. A successful BIND request then changes the state to the distinguished-name in the BIND request. How does the authentication process enable Single Sign-On (SSO) to allow an end user accessing resources within multi-domain forest enterprise without having repeatedly supply their logon credentials. By enabling single sign on, a single credential is created for signing in to multiple servers/resources. Hence, once the sign in process is completed for any one of the account, the need to sign in separately to other services cease to exist. This is achieved by means of the Remote Desktop Gateway (RD Gateway) role service. AD FS requires each server to have a certificate that used for SSL communication. Discuss each task that is involved in issuing an SSL certificate to root CAs authentication process. The Active Directory used the SSL communication for authentication of the client on server using certificate. The certificates are generally self-generated certificated using GPU license, and are provided to client separately. We plan to use all the three services, because they have different roles, and they will help keep the server status healthy and bug free, and reduce the efforts in manual maintenance. Methods Feature Description Does it Require for your Prototype Yes or No Authenticate to a Web Service or Application Integrated Windows Authentication Digest Authentication Provides automatic authentication for connections between Microsoft Internet Information Services, Internet Explorer and other AD aware applications A username/password based authentication method that uses MD5 cryptographic hashing on the username and password prior to transmission on the network. Yes Authenticate within an Active Directory domain Kerberos An authentication protocol that involves manual authentication using symmetric key cryptography and a trusted third party, and public key cryptography as well during some phases. Yes Authenticate to legacy applications NTLM A suite of protocols developed by Microsoft which combines the LAN Manager protocol, NTLMv1, NTLMv2 and NTLMv2 Session into a single package, implemented as a Security Support Provider. No Extend modem authentication protection to legacy systems Extended Protection for Authentication A set of security updates to the Integrated Windows Authentication that help protect user authentication credentials when IWA is used. No Leverage multifactor authentication Smart card support Biometric support Windows devices equipped with a suitable scanner can use either smart card authentication or facial recognition/finger print scanning, or any combination of these technologies to obtain user authentication. No Provide local management storage and reuse of credentials Credential Management Local Security Authority Passwords Yes Secure authentication on the web TLS/SSL as implemented in the Secure channel Security Support Provider Yes

Carbon Fibres and Composite Material Free Sample for Students

Question: Write a Research Paper on a Composite Materials of your Choice used in Medical Application. Answer: Introduction According to Goodman et al. (2011), a composite material refers to a combination of two or more materials that are of different composition, physical property, and morphology. These materials are often combined on a microscopic scale. Depending on the constituent properties, composites are in many cases designed to (or intending to) producing materials with materials aimed at fulfilling specific mechanical, physical, or chemical requirements. As a result, Hofmann (2016) points out that the use of composite materials have progressively increased for the past 40 years and have many uses in the automotive, aeronautic, medical, and naval fields among other industries. Consequently, different composite biomaterials have been tested and studied for use in the medical field and are often commercialized for their advantages of the traditional composite materials that were used before. In the medical field, most human tissues such as skin, bones, tendons, teeth, and ligament are composites made up of single constituents whose distribution, morphology, amount, and properties are the major determinants of the final behavior of the resulting organ or tissue according to Paknikar and Kumbhar (2015). The same study denotes that human-made composite materials can as well be used in making prostheses that are used to mimic these biological tissues with the aim of ensuring thy match their mechanical behavior and restore the mechanical functions of the body tissues that have been damaged. This paper presents the history, structure and synthesis, mechanical properties, possible uses, as well as pros and cons of the carbon-fiber-reinforced, peek (CFR-PEEK) composite material whose use have been studied, tested, and proven fit for medical purposes. History of the Composite Material Carbon Fiber, a polymer that is also known as a graphite fiber, is a very strong material and light in weight. Though stiffer than steel, its light weight makes it suitable for use as a raw material in the manufacturing of other materials (Garry, 2013). The composite material was discovered back in 1879 by Edison Thomas. The scientist backed bamboo silvers and cotton threads at high temperature carbonizing them into a fiber filament of all-carbon. His invention led to the use of high-performance carbon fibers in 1958 in Cleveland. CF-PEEK was then introduced as a matrix where long and short PEEK fibers were used as the composite matrix to ensure the end product had the qualities of both fibers. Despite the fact that they were inefficient, the fibers contained approximately 20% carbon with low stiffness and strength properties. However, the carbon fibers strength potential was realized in 1963 through a new manufacturing process at British research center (David et al., 2014). In the medical field, carbon-fiber-reinforced peek materials range from large scale components such as x-ray application materials to most invisible bolts internally used to support the bones in the body according to Paknikar and Kumbhar (2015). CFR-PEEK materials have for a long time been adopted for use in the medical field in different facets. They are widely used in the orthopedic processes mainly for bone crafts, bone cementing, hip joint replacement, and in the fixation of the bone plates in the body. Hofmann (2016) points out that CFR-PEEK can be fabricated with tensile strength or stiffness in the capability of the bone they replace in the body. As a result, the materials are successfully finding their way into the medical devices as implants to replace the internal body organs and tissues. Historically, many challenges have been faced by implant designers in achieving acceptance from different regulatory agencies globally. However, the uses of carbon-fiber-reinforced peeks are on the rise as a result of technological advancements and innovations. New medical applications and composite materials are gaining popularity and approval in many parts of the US food and drug administration (Garry, 2013). CFR-PEEK are used in the formulation of bone growths for implants such as temporary bone supports and bone screws mainly adopted in the orthopedic repairs. These materials have been adopted for use in the bioresorbable polymers that can safely break down and be absorbed by the body in the rebuilding process of the bone. Sturucture and Synthesis of the Composite In the medical industry, the first synthesis requirement is a performance parameter indicating the relative merits of different designs of CFR-PEEK with the primary knowledge that the growth and micro-motion of bones can be used for different purposes in a clinical view. What follows is a finite element code that determines the strains in the bone used as essential parameters in evaluating the performance of the carbon fiber. The CF-PEEK composite is manufactured by the use of a hybrid fabric composing of PEEK and carbon fiber as a matrix that is then modified and treated by low temperature and oxygen plasma. The process is then followed by X-ray photoelectron spectroscopy, Fourier transformation attenuated total reflection infrared spectroscopy (FTIR-ATR), and Scanning Electron Microscopy (SEM) that are essential I relating the functionality and roughness of the carbon fiber surface with the PEEK interfacial adhesion strength. The plasma treatment is aimed at increasing the roughnes s of the carbon fiber surface while the prolonged treatment results into the smoothing. Figure 1: The structure of carbon According to Duraccio, Mussano, and Faga (2015), the structural properties of a composite material are determined by the length, volume, and alignment of the carbon fiber it contains. Apart from being strong, carbon fibers have high tensile strength and stiffness but with low weight. It also has a high chemical resistance and is often tolerant to high temperature and excessive heat but with a low thermal expansion as denoted by Garry (2013). Mechanical Properties According to Cano and Guilemany (2016), the mechanical property of a composite material can be determined by the mechanical properties of CFR-PEEK. Carbon fibers consist of strong and thin crystalline carbon filaments for the strengthening of other materials. David et al. (2014) denote that the fibers can be thinner than the human hair but gets its strength when the fibers are twisted and laid over a coated and molded into plastics or resin. For these mechanical properties, carbon fiber is adapted for use not only in the medical field but many industries such as the military, automotive, and aerospace. There are two main forms of carbon fiber incorporation used in composites for medical applications. Short CFR-PEEKs that consist of short carbon fibers randomly aligned and are mostly less than 0.4 mm, used as producers of the homogeneous material property for the implant. Long CFR-PEEK consists of carbon fibers essentially running the entire width of most composite materials. The long CFR-PEEK has a tensile strength that is greater than 2000 Mpa when compared to the 170 Mpa which is of the short carbon fiber (Aspenberg, 2014). As a result, their controlled alignment of these carbon fibers hence helps in providing a broad range of anisotropic properties that can be controlled for specific functions depending on there the composite material that needs to be made and the use. Figure 2: A summary of the mechanical nature of carbon-fiber-reinforced peek Advantages and Disadvantges of Carbon Fibers Ajioka et al. (2016) denote that carbon-fiber-reinforced peek material is engineered to produce a varying degree of stiffness and strength based on the number and orientation of the carbon fibers used. It is hence easier to help the manufacturer match the elasticity of the bone to be replaced with the composite implant material that will be fixed. On the other hand, Paknikar and Kumbhar (2015) also denotes that using carbon fibers as composite materials is easier since, before their innovations, manufacturers were facing challenges from modulus mismatch of the then used metal implants. For instance, the mismatch was often producing stress shielding; alter loading, and a periprosthetic bone remodeling process that was often detrimental. Commercially available carbon fiber composite materials have been tested in several ways for fatigue cycles but have always proven to be effective and resistant. Nayeri (2014) denotes that the average strength for a 4.5mm implant plate is 19.1 Newton meters while that of a similar 4.5mm stainless steel compression plate is 17.8 Newton meters. The bending strength of available 10-mm CFR-PEEK is averagely 80.3 Nm, while an 11-mm titanium tibial plate bending strength is 43 Nm. This has proven that the testing for wear debris of the implants is significantly lower than the wear debris strength of titanium plates made from the steel as pointed out by Goodman et al. (2011). The same study denotes that the healing and fracture reduction are available for a standard radiograph. The absence of both MRI and computed tomography means that CFR-PEEK for the composite implants has applications for infections, spine, and for oncologic cases. Even though there are several advantages of using the carbon-fiber-reinforced peek composite implants for medical reasons, there are also some specific disadvantages. For instance, they cannot be contoured hence making their use in fracture fixation limited to straight diaphyseal hence calling for a specific locking screw technique anatomically designed for the specific fracture Utech and Boccaccini (2016). At the same time, stiffness can be beneficial to the receiver, but the too much flexibility is as well dangerous as it can lead to pseudarthrosis. The increased fatigue strength of the implants helps in decreasing any possible risk to fatigue failure. However, the radiolucent nature of the carbon-fiber-reinforced peek used in the manufacturing of the implants precludes directly hence visualizes radiography. Possible uses of Composite Implant In his study, Hofmann (2016) denotes that all biomaterial composites intended for use in the body of any living organism have to meet certain conditions, regulatory requirements, and criteria. These include; The material should not release any harmful components into the living system of the organism Must be biocompatible such as tissue or blood compatible, nontoxic, or non-carcinogenic The physical and mechanical properties of the material such as durability, stability, and elasticity must be suitable and appropriate for the intended application. The mechanical properties of the material have to last for the projected life of the implant or the medical device A sterilizable material by a standard method Carbon-fiber-reinforced peek have found a wide application and use in different facets of the medical sectors. These include bone cementing, bone grafting, hip joint replacements, bone fixating plating, and other forms of bone replacements (Asghari et al. 2017). In the manufacturing and design of prosthetic composite implants used for the replacement of the central bone and the combined joint, the primary objective is often to arrive at an implant with a higher bone growth stimulus but slightly lower that the titanium alloys implants that are currently used (Egger et al. 2017). From the CFR-PEEK innovations, patients can easily get access to rapid and easier proper implant fixation and bone replacement. Achieving these objectives requires the synthesis and structure of the composite implants to consist of three primary elements. In his study, Soboyejo (2017) points out that CFR-PEEK includes bio-glass-ceramic, xenograft, and allografts often used in joint replacements and tissue engineering. They are often made of different layers of long and short carbon fibers; the final product often combines the properties of both the materials used. The resulting product is often mechanically strong but lightweight at the same time. Saleh (2016) also denotes that the materials have low density and can easily resist corrosion. The use of composite body implants has several advantages when compared to the metallic devices that were used before their inventions. It modules if elasticity and fatigue strength makes the CFR-PEEK an ideal composite implant material for bones plates and nails. Environmental Impacts The disposal of CF-PEEK is becoming a major issue since the different carbon fiber reinforced composite materials are reaching the end of their live services. According to Schinner, and Brandt (2011), over 27 000 tons of CF-PEEK have produced annually. As a result, grinding up the waste material and sending it to landfills or disposing of it through incineration has little appeal to the environment since it is non-biodegradable. With global warming and climate change policies affecting every global industry, incineration is not the best method of disposal of the material as it will lead to the production of greenhouse gasses as well as smoke, thus leading to pollution. Disposal into landfills also reduces the aesthetic value of the environment turning the areas into wastelands and creating environments for disease-predisposing factors such as stagnant water collection points for mosquito and bilharzia breeding when it rains. As a result, different recycling methods such as pyrolysis have been adopted that strips away the epoxy resin from the fibers while leaving the original properties undamaged. Conclusion The medical industry is driven and guided by the demands of the medical profession that seeks constant improvements and device innovations for better medical care. Consequently, different composite biomaterials have been tested and studied for use in the medical field and are often commercialized for their advantages of the traditional composite materials that were used before. Carbon fibers have found a wide application and use in different facets of the medical sectors. These include bone cementing, bone grafting, hip joint replacements, bone fixating plating, and other forms of bone replacements.
