Lady Macbeth is the real driving force behind the murder of Duncan Essay

Lady Macbeth is the real driving force behind the murder of Duncan Discuss this statement and decide whether or not you agree (1000 words) - Essay Example He is praised and made to feel successful. Discovering that Macbeth is a kinsman to the King Duncan, the audience learns of his bravery and ability on the fields of battle, but they see nothing yet of base envy, or of any desire to rule the country. His loyalty and respect for Duncan are not put into question. But the encounter with the witches plants the seeds of ambition and arrogance. Macbeth is silent while Banquo answers the witches. His mind is at work, and in his heart is growing the seed of evil. Elements of treachery enter the scene, and delusions of grandeur infiltrate where before there were none. ‘If chance will have me king, why, chance may crown me, / Without my stir.’(Act I, Sc 3). Still, he does not exactly leave it to chance, even if he thinks he does not have to do much. He puts the whole thing in a letter to his wife. From the apparition on the heath, desire for power has entered the credulous thane’s spirit, like a curse cast on completion of a successful battle. All of a sudden, being a respected thane is not enough. Through the fateful flaw of being gullible, and believing tenuous predictions, Macbeth is spellbound. This gullibility leads him to ignore his formerly good conscience and become obsessed with gaining what he had previously not even considered for a moment to be rightfully his: ‘to be king / Stands not within the prospect of belief,’ (Act I, Sc 3). Bewitched, he ruminates repeatedly on the prospect of authority and power. The curse travels inside a letter from Macbeth to his wife, who reads it, entranced. She cannot wait for Macbeth to return, so she can persuade him not to be so timid: ‘Hie thee hither, / That I may pour my spirits in thine ear; / And chastise with the valour of my tongue / All that impedes thee from the golden round.’(Act I Sc 5). She knows that so far, her husband has proved himself to be a good man, and fears he might be too nice to share her

Risk and Return Assignment Example | Topics and Well Written Essays - 2000 words

Risk and Return - Assignment Example According to CAPM, r = Rf +? (Km - Rf ) Where r= Expected return of the security Rf = Risk free rate ?=beta of the security Km= expected return of the market RA= 0.06+0.27(0.25-0.06) =0.1113 =11.13% RB =0.06+0.75(0.25-0.06) =0.2025 =20.25% Characteristic Lines of Securities A and B The SCL:Ri,t -Rf =?i +?i (RM,t - Rf ) + diversifiable risk ? is the excess return ?i (RM,t - Rf ) represents the non diversifiable risk The security characteristics line is drawn to show the excess return of the investment over that that of the market. The y-axis represents the excess return over the risk free rate. The x-axis represents the excess return over the market in general. The slope of the SCL represents the beta of the individual security. The main reason for the determination of the security characteristics line is to show the performance of a security relative to that of the market. Investors who want to put their finances in investments are interested in securities that will pose performance that is higher than the market or is at par with that of the market. From the slope of the security characteristics line, it is easier for investors to see the alpha of the security and also to compare the performance of the security relative to others. Moreover, a security characteristics line reveals the quantity of both the systematic and unsystematic risk (Roll & Ross 1980). Systematic risks are those that cannot be minimized through diversification and the investors must avoid investments with higher systematic risk. Likewise, the level of unsystematic risk can also be revealed from the diagram. To interpret the diagrams, the lines with high gradients re taken to have a higher beta factor and are therefore more risky than those with lower gradients. At the same time, the return of securities with higher gradients will exhibit high return level. In the diagram as well, the y-intercept represents the alpha value i.e. the excess of the return of an investments over the risk free r ate of return (Roll & Ross 1980). On the other hand, the x-intercept represents the excess of the security return over that of the market. A security with a high value of X-intercept has a higher return than those of the lower x-intercept values. It is therefore clear that a security characteristics line is an important tool that investors rely on when making investment decisions and should be able to help in the making of investment decisions. The security characteristics line therefore reveals the properties of the respective securities. Question 2 The arbitrage pricing theory is an asset pricing model that was developed due to the limitations of the capital asset pricing model. APT is a multifactor model that considers the various macroeconomic factors affecting the pricing of a security (Roll & Ross 1980). In this model, the risk free rate is added to all the macroeconomic factors affecting the pricing of the asset with each factor having its own beta. According to the arbitrage pricing theory, the return of a security is determined by the formula: r= Rf + ?2F2+ ?3F3+†¦..+ ?nFn Where r=return of a security ? i’s=betas of respective factors Fi’s= macroeconomic factors affecting the returns The APT is therefore a multifactor model and the arbitrage process is the selling of the inefficient securities in inefficient markets in order to maximize the return on the assets. In this process the overvalued assets are sold in order to get the profits and undervalued

Wireless Network System for an IT Training Centre Essay

Wireless Network System for an IT Training Centre - Essay Example This information is then transmitted through the air with the help of a transmitter and received at the other end through a receiver and demodulated. Since both transmission and reception of the signals have to be carried out at the same point, therefore a device known as an ‘Access Point’ (AP) is used which is a simple transmitter/receiver or transceiver. By assigning different frequencies to different users many users can access the network simultaneously without interfering. As is evident, the access to a wireless network can be gained only if the users are having devices which have a wireless facility. These devices such as notebook computers and tablet PC’s are widely available in the market and their prices have fallen by large amounts in recent times making them affordable. Â  Depending on the designing technology used WLAN’s are mainly of three types. ‘Narrowband wireless LAN’s’, ‘Spread Spectrum wireless LAN’s’ and ‘Infrared wireless LAN’s’. Narrowband WLAN’s, as is understood from the name, use the narrowband signal for communication. Therefore the speeds achieved are low in this case but the problem of interference is greatly reduced as is the case with narrowband signals. The problem of low speeds is solved by the Spread Spectrum WLAN’s which use wideband signals. The drawback of this technology is that the number of users accessing an access point is lesser and the security is also weaker than Narrowband WLAN’s. However, in spite of these drawbacks, it is the most widely used technology. The infrared WLAN’s don’t find many uses as the speeds as well as the range, in this case, is very low. Infrared WLAN’s are used only when the devices and access points are placed close to each other and when they are in the line of sight. The requirement of devices to be in the line of sight is because RF signals cannot pass through opaque objects. Â

Russia and China Foreign Policies on Central Asia Research Paper

Russia and China Foreign Policies on Central Asia - Research Paper Example The interest that China has in Central Asia is not new. The course of the interest in Central Asia entails their concern to extent control over the territory as well as control the territorial security. The sign of interest in this complex advancement is evident from the sustained rhythm of successive visits, since the first tour of Prime Minister Li Peng in 1994. Thus, the guiding thread of China’s foreign policy in relation to Central Asia is essentially to achieve â€Å"stability†. The country of China exists in a political territory that continues to experience restlessness from je frontier zones to the periphery, despite the ending of the Cold War, a course that raises new series of risks. The collapse of the Soviet system and eventual independence of the Central Asian republics marked a remarkable fragmentation of the region in additional to continued autonomisation of the entire region. The effect is that a multitude of opportunities that existed and the stakes entailed for the Peoples Republic of China received a remarkable blow, becoming rather complicated (Lanteigne, 2009). The course is that the movement towards achieving the foreign policy compromises is yet far from conclusions. Another concept entailed in the foreign policy regarding Central Asia is the end of the communism practice in 1989 I the USSR, which in effect granted the republics in the Central Asia region greater liberty (Lanteigne, 2009). Moreover, this development unfortunately coincided with the resurgence of the democratic calls entailed in Beijing, which marked a beginning of a period of agitation in China and the larger region. Notably, the disappearance of the Soviet threat in the region from the end of the Cold War marked the beginning of bilateral relations of the dimensions between China and Central Asia. The course in the 1990s, seemed to take a positive direction as China sought to weave

An analysis for Lewis'relection following the death of his wife Assignment

An analysis for Lewis'relection following the death of his wife - Assignment Example Events involving loss or separation may occur throughout our lives (Lendrum & Syme 2004) but death is a particular form of loss that is very different from the loss of innocence or control, such as in sexual abuse or rape; or loss of status and income such as in retrenchment or unemployment. It is also vastly different from the loss of dreams or ambition such as in the birth of a disabled child. Death is not only devastating, it is final, (Lendrum & Syme 2004) and any counselling that occurs must take into consideration that bereaved persons understand this in different ways. Different individuals have varying concepts on what death brings, not only to them as the bereaved, but to the person who has died (Walton 1996). Not everyone believes in the hereafter, and that souls are reunited after death. Not all believers share the same concepts about death and resurrection (Duffey 2007). There are many variations on both philosophies. C S Lewis is well known for his Christian outlook, with an understanding that eternal life lies ahead for all souls, but a variety of these concepts exist in the community (Blank 2009). In addition, the shock of bereavement can give any person a new insight into their long-held beliefs. So allowances must be made; and jumping to conclusions, or making presumptions, must be avoided if possible (Kubler-Ross & Kessler 2007) . Just as C S Lewis had to redress his faith when his beloved wife died (Lewis 2001), many of those recently bereaved experience a shift in attitude - no matter how long they were held - that comes through shock and disbelief. Initial distress can often register as physical pain (Malkinson 2007). Lewis suffered from osteoporosis, so he was no stranger to pain, but the loss of ‘H’ struck him like an ache from which there was no relief (Lewis 2001). Reaction to the death of someone

Inter-vendor Storage Management Application Tools Essay Example for Free

Inter-vendor Storage Management Application Tools Essay Inter-vendor storage application management tools are huge enterprise software applications that are used for robust, reliable, available and effective data management. The applications are both hardware and software dependent. The choice of their implementation depends on the organizational needs and objectives. Various vendors develop and support these tools both for support of business and mission critical applications. Some of the leading Inter-vendor applications tools that have dominated the industry as well as organizational automations in the last two years include VERITAS, Oracle and NetApp (ESM, 2009). VERITAS Its application tools provides for automated storage management software for enterprise business applications which have increased dependence on data from corporate storage infrastructure. VERITAS application tools are vital for boosting administrator productivity and reduce errors in automated storage administration. Among the tools it provides is the Storage Resource Management (SRM) software tools that help to automate the erroneous, tedious and routine tasks in storage administration. The tools are able to predict when the problem is likely to happen and as a result the IT managers are able to head off these problems. The automated storage provisions help the administrators have a continuous, uninterrupted access to the enterprise storage resources. The storage administration by the automated SRM software can accomplish several tasks in use, management and applications of the storage allocations. The automation tools are able to gather data around the storage infrastructure and also give feedback on the successful storage policies and also provide input and reports on the storage environment. The accurate and timely data help managers make informed and intelligent decisions on the future use of the storage. Further administrators are able to report and monitor on resource utilization and performance. When applications crash, the pagers beep and systems panic, it is the administrator that is on the receiving end of a pager to get the problem notification. Such situations prove to be very critical especially for business users due to degraded performance, equipment failure, resource shortages, and corruption of data or storage problem risks. This interruption of application access may in turn lead to incalculable financial losses to the business or organization. Therefore the automated software provisioning has a framework that manages the growing inventory in the components of enterprise storage. When the SRM software tools are deployed into the automated storage provisioning framework, the administrator has an easier access to the event based interventions and rule based policies which adequately resolve and intercept potential problems before they reach their critical levels (Hussain, 2008). The storage management application tool for a web based directory assistance runs on a web server as a data entry component with a more sophisticated management application that runs on a separate application server. When data is entered for the directory assistance, it is updated on the web server and staged on the repository application server and it is then automatically transferred to a relational database in another server by the directory management application. For fault tolerance as provided by the database server, database tables are duplicated using the snapshots from the primary database. The services however are vulnerable to storage failures especially when space allocation to the web server, database and repository is threatened to be exhausted and as a result bring down the system. Organizations of all sizes and in all industries are dependent on enterprise technological infrastructure which means that there is immense need for automated storage management process to avert any failures in the enterprise storage infrastructure. Therefore the SRM software tools and the automated storage provisioning should be implemented to solve the storage management problems. The rule based storage automations streamlines the administrator’s routine which improves productivity, reduces potential errors and system’s availability which impacts business activities and application availability. Oracle and NetApp The Automatic Storage Management (ASM) application tool provides a way to manage storage with an underlying database on a volume manager for the files on the database and an integrated file system. Its gives an alternative to the volume management solutions and file systems for the storage management tasks in the database (Manning Bridge, 2009). On the other hand NetApp filers simplify management and deployment of the enterprise data. The ASM and NetApp storage lower ownership costs and save on costs through the configuration of combined technology. There are combined benefits for using the NetApp for database layered applications and Oracle database which includes practices for deployment of ASM with the storage solutions networked by NetApp. Oracle ASM on NetApp iSAN and SAN storage like Oracle on NAS storage by NetApp has alternative capability for volume management for customers on an Oracle server that can alter, drop and create SQL statements which simplifies the storage provisioning on the database. The NetApp and ASM storage application tools has features that complement one another in performance to avoid errors by balancing of workload and help utilize the disk drive resources available. They also provide for support of online removal and addition of storage capacity that help maximize data availability and at the same time making configuration changes in the storage. The applications tools provide data security and availability since enterprises require high levels of data availability and protection whether there are component failures or faults storage subsystems. These tools include NetApp mirroring solutions that offer protection for disaster recovery requirements and business continuance while ASM provides protection against storage failures. In shared storage, Oracle’s Real Application Clusters (RAC) provides scalability and availability for the Oracle database which requires all servers to have direct read and full access to the database files. The ASM implementation provides a simplified cluster file system with optimized functionality of the volume manager in the shared storage. The NetApp networked storage gives shared access as required by RAC while in SAN environments, ASM provides volume management by Oracle RAC and a capable clustered file system. Both application tools have a rich assortment of storage data management that can be used separately or when combined depending on the customer enterprise requirements or the data infrastructure (Animi et al, 2009). The Automatic Storage Management application tool simplifies the management and configuration of storage management for the Oracle data files in its database. It also complements iSCSI SAN products for storage and NetApp Fibre Channel and while combined, they give full value to both technologies. With several combinations for data storage management and protection exists in the market, the Oracle and NetApp partnership offer powerful combinations that offer best practices to meet business performance and high availability requirements. Storage Management Networking Industry Association (SNIA) SNIA has created Storage Management Initiative Specification (SMI-S) application tool in order to standardize and develop storage management technologies for networking and storage. The SMI-S is for a standardized interface like SAN based storage management which are a challenge for interrogators and end-users to manage especially for multivendor SANs. The applications developed in most cases are unable to work together or are uncoordinated to perform tasks and deliver functionality, security and reliability for increased business efficiency. SMI-S therefore specifies protocols to manage communications with incorporated mechanisms for standard based management. It unifies the storage networks and also the management tools. The set of interfaces will allow the control of heterogeneous storage by storage management software packages. This way storage administrator will create and delete volumes and zones and also monitor array controllers, switches and host bus adapters. The enterprises too can manage with a single management framework their storage capacity independent of manufacturers. The application features have a common and extensive management transport, which has unified and complete which provides control of Zones and LUNs in a SAN context. It also has an automated discovery system with a newer approach in application of the CIM/WBEM technology. This specification helps to secure a reliable interface that can allow for the storage management interface classify, identify, control and monitor logical and physical resources in a SAN. The Technical Specification defines the management of a heterogeneous SAN and describes information from a SMI-S compliant CIM server available to a WBEM client. This information is object oriented, message based, XML based interface that is designed to support requirements of the managing devices through and in SANs. Using the CIM-XML on HTTP standard which is an independent management protocol, vendors increase the functions and features of their products without having to redesign the management storage therefore reducing cost and extending functionality. The SMI-S functional capabilities include the version requirements as provided and stated in the interface. Among them is that it will be able to receive the asynchronous notifications incase the SAN configuration changes. It will also be able to identify the health of vital resources in a SAN and also receive the asynchronous notification incase the SAN resource’s health has changed. It will also identify interconnects available performance in a SAN and receive the asynchronous notification incase a SAN’s interconnect performance changes. It will also identify zones that SAN enforces and help enable or disable, delete or create zones in a SAN. It will also identify the access rights and connectivity to SAN Storage Volumes and also enable or disable, delete or create access rights and connectivity to SAN Storage Volumes. These standards and specifications can only be used by a WBEM compliant and authenticated client. The language chosen for managing information and other related operations is the XML language which will help traverse the organizational firewalls and installed at low costs (Cover, 2010). In midrange computing environments and enterprise class, the SANs are highly emerging due to various functions and applications such as sharing of huge storage resources between multiple systems and having a LAN free backup. Other applications include disaster tolerant and remote online mirroring of critical data and clustering fault tolerant applications and systems with one data copy. While emergence of SANs accelerate, the informational industry requires a management interface for different classes of software and hardware products for multiple vendors to allow interoperation and reliability in order to monitor and control resources. For this reason SMI-S was created to define this interface and provide a standard for heterogeneous, functionally secure and reliable control and monitoring of resources in the complex distributed Inter-vendor SAN topologies. The SMI-S standard can simplify the huge storage management and reduced costs in storage administration but has not solved all storage problems. Since storage is an integral part in IT infrastructure to be managed with a combination of servers, applications and networks, management solutions offered by SMI-S work for servers, storages and networks. In the storage infrastructure, it provides the end-users with a consistency for device discovery, configuration and status information. SMI-S defines the behavior and structure of devices and their management and configuration in the storage infrastructure and provides management of multiple storage devices from multivendor. However, it does not solve the problem of incompatibility of hardware devices from the different vendors while its domain in storage management does not cover remote replication and backup. Conclusion There is countless demand by customers for open software from the computer industry vendors which is the reason multiple vendors such as Oracle and NetApp have had to work more closely to develop common standards, protocols and languages for storage and network management. The multipurpose standards could help storage administrators take control of the distributed applications with a resulting inter-vendor, manageable and open information systems. Using standard based storage management application tools can help increase value of IT investments. Before the multivendor standards were developed by SNIA, the individual users would need to manage the storage devices with vendor specific tools while disparate information was integrated manually. Today’s management standards and specifications are increasingly interoperable while still maintaining competitive advantage among vendors through differentiation.
