MRSA Research Paper Example | Topics and Well Written Essays - 750 words

MRSA - Research Paper Example MRSA is a nuisance in hospital for the patients with open wounds or on invasive devices and bothersome for immunocompromised patients. The study reports MRSA to be the major cause of illness and mortality in the hospitalized patients and thereby enhances the burden of hospitalization cost. The research reports the mortality associated with MRSA between 1999- 2005. However, the article does not report the variation of cases in different hospitals to highlight the need of intervention required in a particular hospital to rule out the cause and take steps to eradicate MRSA as done in the study carried out by Hardy et al, (2007). The article considered evidence based research to highlight allocated resources to deal with MRSA and emphasize on the decision of policy makers to adopt control measures, but the article does not state the control measures to be adopted in different hospital settings to check spread of nosocomial spread of MRSA. On the other hand the study carried out by Hardy et al, (2007) specify the microbiological identification of patients followed by the isolation of such cases to prevent cross-infection together with application of mupirocin and skin disinfectant in order to remove the chances of any carriage. The article emphasize on thorough screening and isolation. According to Hardy et al, (2007), the interventions to control MRSA infection are poorly designed and including nurse cohort in bays. The screening method that is suggested by Hardy et al, (2007) directly implicate the molecular methods for detection of MRSA such as multiplexed PCR primers to detect the presence of gene (mecA). Methodology The methodology adopted was based on estimated incidence, i.e. the number of hospitalized cases with S. aureus-related discharge. The Surveillance Network (TSN) Database- is an electronic repository of susceptibility test is utilized to test the drug resistance patterns. However, the study highlights NHDS report on the mortality of the patient but t he reason of mortality was not specified. The report estimated only those mortality cases which were involved with MRSA. On the contrary, study carried out by Hardy et al, (2007) was systematically planned involving socio-economic, ethnic as well as age characteristics. It involved seven surgical wards encompassing general surgery, vascular, thoracic, ENT, trauma and orthopedic as well as urology. The study also had inclusion and exclusion criteria of the cases in contrast to the study carried out by Klein et al, (2007) which does not have any exclusion criterion nor does the study involved sampling procedure. On the other hand, study carried out by Hardy et al, (2007) involved nasal samples as they can be procured easily and have 84% sensitivity. The results procured were immediately conveyed to the staff of the concerned departments to have laboratory protocol and for patient information and communication. All these actions such as data collection, data analysis, sample size, econ omic analysis, modelling were swiftly performed to control the infection. All these methods were lacking in the study carried out by Klein et al, (2007). Discussion According to Klein et al, (2007), antimicrobial drug-resistant illnesses inflict larger costs as compared to the susceptible infections caused for instance infection caused by Staphylococcus

Exploring Networking Principles Components Computer Science Essay

Exploring Networking Principles Components Computer Science Essay It is a communications model that consumes the similar capabilities and can start a communication session.  This network definitely has no central server. Every computer makes its own functions and may share certain resources with 75 additional users on the network. The whole thing in the network are equal to peers which means they dont need a server role to play. Peer to peer network is easily to install and always set up in home environment as well as minor businesses. But every computer need to be conserved individually that can lead to undependability inside the network. The benefits or advantages and constraints of Peer to peer network. Benefits Constraints Easy installation and configuration on the network. The entire system is spread out and hardly to administer. Every information are shared through the peers network. Viruses can simply transmitted. One peer fail to function doesnt gives any effect to other network, therefore it is more consistent. Data recovery and backup is difficult therefore all computer that connects to this network must have its own backup system. User can control their public information which makes every user is the administration for their computer. Software is installed on each computer individually which takes up lots of time. Cost of building and maintain is cheap. Difficult to set up data structures as some private files maybe available to all the users. The Client Server Network It is a form of online network consist of of a single central computer performing as a server that leads to multiple other computers which is called clients. The clients can shared data saved on the computer. Moreover, the client server networks are the same generally to peer to peer networks but the difference is only the server that can start a particular transaction. The client server network can be applied into a single computer system, but then again is most commonly applied over many different sites. Therefore, it is likely for multiple computers to join and share information. Benefits Disadvantages There is centralized control which the servers help to administrate the whole set up. Access rights and resources sharing is done by the servers. Too many requests from clients will result in congestion which can lead to breaking down of servers. Every files is stored in the same place that makes it easily to search for. Client server is not strong therefore if one server is fail, the whole network cannot be function. If incase data is lost, it can be easily recovered efficiently which makes data easy to back up. To maintain the server and technical details of the network, they need professional network people. Server can play different roles for different clients. Expansive to setup and manage Security and access rights can be done during the set up of the server. How Star Tropology is different from the Ring and Bus topologies. Star tropology involve of a central nodes to which all other nodes are connected to central device called hub. The hub then will receives a signal that comes from any node and then passes it to all the other nodes in the network. While the data on a star network will be going through the hub, switch, or concentrator before proceed to its endpoint. This star topology will decreases the chance of network failure by linking all of the systems to a central node. When a building is wired with a star topology, faced cables radiate out from the center to intermediate connection point to wiring cables. This will lets sufficient connection point to be provided for one sub area, while providing flexibility in their allocation within that area. This is the advantages and disadvantages of using the Star topology. Advantages Disadvantages Easily to manage and locate the problems Always needs very long cable length when connecting many nodes More easier to expand If hub connector fails, nodes that is attached are not available. Easy to install and wire More expansive because cost of concentrators. Easy to detect faults and to remove parts Failure of one workstation does not affect the entire network The Ring network in every device will have just two neighbors for communication purposes. Every communications will go through a ring in the similar way. If there is failure in any cable or device, it will breakdown the loop and can take shutdown the whole network. To implement a ring network we use the Token Ring technology or small data packet, is always passed around the network. While a device wants to transmit, it reserves the token for the next following trip around, and at that point it will attach its data packet to it. The advantages and disadvantages of Ring topology is as follows: Advantages Disadvantages The capability to reach transmission rates of the order of 10 million bits per second The breakdown of a single node can affect all network to fail. More easily to accomplish. Changes or any movement made to the nodes will affects the performance of the whole network. Better communications over long distances. Finding fault is difficult. Handles high volume of traffic Isolation of fault is not easy. No central server which reduces the cost of creating the ring topology The Bus topology is the backbone to link all devices. A single cable, the backbone functions as a public communication that devices attach or tap into with an interface connector. The device that wants to connect with another device on the network will sends a transmission communication onto the wire that all other devices see, but only the intended receiver actually accepts and processes the communication. To keep the signal that is send to all computers, from bouncing back and forth along the cable, a terminator will be put at the end of the cable. Only one computer can send data at a time, so the many the computers, the slower the transmission will be. This bus topology is the most popular along the LANs because they are cheap and easy to install. This is the advantages and disadvantages of using Bus Topology: Advantages Disadvantages Cheap and simple Fault diagnosis is difficult Only need short cable length Fault isolation is hard because the entire segment of the bus must be disconnected to isolated the fault. Easy to expand the network Cable length is limited. No risks of data collision since one computer transmit at a time It can perform well only for a limited number of nodes. Perfect for one to many data transmission Signal on the cable are bidirectional hence reaches all the nodes Locating cable fault is easy Task 2: Evaluate the impact of current network technology, communication as standards. Task 3: Discuss the role of software and hardware components. Windows Server System Windows Server refers to every kind of server instance that is installed, operated and managed through the Windows Server family of operating systems. Windows Server shows and also offers the same capability, structures as well as operating mechanism of a normal server operating system and is created on the Windows NT architecture. Windows Server is usually capable of providing server-oriented services, for example the capability to host a website, user management, resource management across users and applications, messaging, security and authorization.  Windows Server software includes, Windows 2000 Server, Windows Server 2003, Windows Server 2008, Windows HPC Server 2008, Windows Server 2008 R2 and Windows Server 8. How Windows Server System is different from Workstation System. Windows Server System device that make service for connected clients as part of client server architecture. Furthermore, it can be a computer system that has been selected to runs a specific server application . It can also serve applications to users on an intranet. A workstation could also contain special audio, video, or processing cards for distinct editing work. The Workstation is a personal computer that is used for high end applications such as graphic design, video editing, CAD, 3-D design, or other CPU and RAM intensive programs. Typically, it has a top of the line, fast processor, multiple hard drives, and a lot of RAM memory. A workstation is promoted by computer manufacturers to professional users, while the server is more of a usefulness device. The differences in function is that the servers save files such as  html, images, video and applications accessible online for the client computer to use. Several computers is allow to share applications or an internet connection. The function of a workstation is to complete high end applications for example, graphic design, video editing and many more. The Workstations are mainly to be used by one person at a time. Even though they can regularly be accessed remotely by other users when needed. But, the Servers work on the task of linking the user and generally will have no single user. The different between server operating system and workstation operating system. About the setup: Computer servers come using enough memory for maintenance anywhere from two to hundreds workstations as well as a hard drive have large space to store applications that are large enough to support the same. Workstations originated with plenty memory and hard drive space to support one system. The Applications One computer server will store internet capability, databases and intranet hosting that the other workstations will save the information. One computer workstation houses a portion of the application is create on the server enough to operate smaller projects. The Uses   The Servers will maintain banking, education, governmental and private home networking structures. While the workstations work on the information or data found in those structures. The Operating Systems   Servers can run off a Windows,  Linux  or Unix constructed by operating systems. On the other hand, the workstations characteristically run off the similar operating system with the server does. The Access   Individual network administrators, system administrators, or other system security personnel are acceptable to access to business servers. Workstation access is decided by the individual sources through network administrators. Task 4: Discuss server types and selection requirements. Database Server Database server refers to a server dedicated to provide database services. A database server normally can be seen in a client-server environment where it delivers information required by the client systems. Using a database server, every data of the organization is kept in one location. The Database server , a will client perform SQL requests to the database server. Moreover, in all theories of the Database server serves its own power to produces the request or search the requested result. The Database server some time also known as SQL engine. Every and each database functions are organized by the database server. Several type of computer can be used as database server. It could be microcomputer, minicomputer as well as mainframe computer. The mainframe computers are used as server in a large organizational businesses. The Database server manages the recovery security services of the Database Management System. It carry out the limitations that are specified inside the Database Management System. It controls as well as manages each clients that are connected to it. This will handle all database access and control functions. Several users can access the database at the same time. The whole data is stored on the data server therefore, the Database administrator can easily form the backup of the database. Database Software and Hardware requirements: The processor needs minimum of 2GHz or higher. The memory will have minimum of 1.5GB RAM but if for the best result users also can use the 2GB RAM. Disk space minimum of 2GB required for product package installation and the resources that users develop. The display must be 1024 x 786 display minimum using 256 colors or more for the better outcome. Use the Eclipse and JDK versions. This version of the product was developed for use with Eclipse 3.4.2, using the IBM ® JDK 1.6 SR 5. These versions are included with the product package. While considering a databases in the client-server model, the database server could be the back-end of the database application or could be the hardware computer that hosts the instance. Occasionally, it might referring to the mixture of both hardware and software. In mid-sized installation, the hardware database server normally host the server part of the software application that uses the database. This request will connect to the database through specific ports and use inter-process communication to log into as well as to access the data local in the database. However, in the large setups, there might be like one computer will be unable to handle the load the capacity of connections. A database software will exist in a dedicated computer, and the application on another. Web Server A Web  server  is a program that, using the  client server  model and the World Wide Webs Hypertext Transfer Protocol (  HTTP  ), serves the files that form Web pages to Web users. All the computer on the Internet that contains a Web site must have a Web server program. Two leading Web servers are  Apache  , the most widely-installed Web server, and Microsofts Internet Information Server (  IIS  ). Other Web servers include Novells Web Server for users of its NetWare  operating system and IBMs family of Lotus Domino servers, primarily for IBMsOS/390  and  AS/400  customers. Web servers usually arise as a part of a larger package of Internet- and intranet linked to software package for serving e-mail, downloading requests for File Transfer Protocol (  FTP  ) files, and building also publishing Web pages. Considerations in choosing a Web server include exactly how good it works with the operating system, its ability to handle server-side programming, security characteristics, and publishing, search engine, and site building tools that might come with it. Function of web server AddHeader Offer by the Web Server. ISAPI filters call this function to add an HTTP header to the outgoing response. AddResponseHeaders Offer also by the Web Server. ISAPI filters call this function to add a header to the HTTP response. AllocMem Offer by the Web Server. ISAPI filters call this function to allocate memory from the process heap to a buffer. GetExtensionVersion This function is called by the Web Server when the ISAPI extension is first loaded for the function name defined by the header. GetFilterVersion This function is the main entry-point function offer by the Web Server on your ISAPI filter, and must be present for the filter to work correctly. GetHeader Offer by the Web Server. ISAPI filters call this function to retrieve a header from the Web Server. GetServerVariable (ISAPI Extensions) This is an application-defined function. ISAPI extensions call this function to save information about an HTTP connection about the Windows Embedded CE Web Server itself. GetServerVariable (ISAPI Filters) This is an application-defined function. ISAPI filters call this function to save information about an HTTP connection or about the Windows Embedded CE Web Server. HttpExtensionProc This is an application-defined function. It is the core entry point for an ISAPI extension called by the Web Server. HttpFilterProc This function is called whenever a notification event for which the filter has registered (in GetFilterVersion) occurs. ReadClient This is an application-defined function. ISAPI extensions call this function to read data from the body of the clients HTTP request. ServerSupportFunction (ISAPI Extensions) This is offers by the Web Server. This callback function is supplied in the extension control block that is related with the current HTTP request. ServerSupportFunction (ISAPI Filters) This callback function is offers by the Web Server. ISAPI filters call this function to achieve a wide variety of tasks. Hardware and Software Apache HTTP Server This software is created under the Apache license, which makes it free and open source. Apache is accessible for a range of operating systems, including Unix, Linux, Novell Netware, Windows, Mac OS X, Solaris, and FreeBSD. Microsoft Internet Information Services (IIS) This comes as an possible component of most Windows operating systems. IIS can be install by using  Add/Remove Windows Components  from  Add or Remove Programs  in the Control Panel. Sun Java System Web Server Based on the Sun One Web Server, the Sun Java System Web Server is designed for average to huge business applications. Sun Java System Web Server is available for most operating systems. File server A file server is a computer in charge for the essential storage as well as the management of data files and the computer on the similar network can view the files. It lets users to share the data without physically moving from one to another computer. Whichever computer can be organized to be a hos as well as to act as a file server. A program or instrument that allows the required processes for file allocation is also refer to a file server. File Server can be used to provide load-balancing between server and also can be used as a storage server to store important documents. Print devices also can be joined to a Print Server and then shared as a single printer. File Server Software Hardware. Windows Server 2008 R2 Standard/Enterprise/ Datacenter Twisted pair 32bit / 1GB or better Ethernet cards Twisted pair switch with sufficient ports Cabling Ethernet level 5 or 6 twisted pair be centrally shared through a Print Server. The thing to consider in File server is when in a Windows ®Ã‚  environment, the file server must both be a member of the identical domain as the management server besides having a trust relationship with that domain.The management server must require complete reading or write access to the share. The user ID as well as the password that were used to install  IBM ®Director Server  have to be also exists on the file server. If not, the software uses have to runs from the management server. The share need to let read access to every managed systems that need to access the share. If the file-distribution server is organized as an FTP server, users can pick to use FTP when relocating packages from the management server to the share. Users also can allow null credentials to access the share so that they dont have to identify a user ID and password for every managed system or group that needs to access the share. In condition to users dont want null credentials, the user have to ins tall operating-system account on the file server. This account need to read access to the share and also to enter the user ID and password to arrange distribution preferences for managed systems. Task 5: Discuss the inter-dependence of workstation hardware with network components. Network Interface Card A Network Interface Card (NIC) is a device that lets computers to be combined together in a network, naturally a Local Area Network (LAN). Networked computers communicate with each other using a specific protocol for transferring data packets among the different machines or nodes. The network interface card acts as an translator, letting the machine to mutually send and obtain data on a LAN. Information Technology (IT) specialists frequently use these cards to setup wired or wireless networks. Function and Purpose of an NIC After building a LAN, a network interface card is set up in every single computer on the network and must use the same architecture such as Ethernet cards, Token Ring cards, or an alternate technology. An Ethernet network interface card is set up in an existing slot inside the computer, classically on the motherboard. The NIC allocates a unique Media Access Control (MAC) address to the machine, that is used to direct traffic amongst the computers on a network.  Network cards  as well change data starting at parallel format, used by computers, to a serial format necessary in data transfers and then back again to accept the data. Wired Networks A cards back plate structures a port that turns a data cable, such as an Ethernet cable, that runs from every NIC to a central hub or switch. The hub acts like a transmission, passing data among the computers through their MAC addresses as well as let them to share assets like printers and scanners. Furthermore, in a wired network, a cable actually joins each computer to each other or to a hub. Wireless Networks Wireless cards are installed like their wired counterparts, but rather than a port for a cable, the card features a small antenna. The NIC interconnects with a central wireless switch or hub via radio waves. Wireless LANs  are frequently suitable, but might have several limitations depending on the material a structure is made from. Choosing the Right NIC When purchasing components for a LAN, it is essential to ensure that the NICs and hub or switch have the similar abilities. The whole network must be either wired or wireless, except if components are specifically chosen that have both functionalities. In addition, different versions of hardware usually support new features plus greater data speeds than older tools. How a network without Network Interface Card Several NIC cards work with wired connections although others are wireless. Most NICs support either wired Ethernet or WiFi wireless standards. Ethernet NICs plug into the system bus of the PC and contain jacks for network cables, while WiFi NICs contain built-in transmitters . Without it, users cannot access to the internet at all because there is NIC connected around the area. There is no signal receiver to transmit data. Network switch A  network switch  is a device that manages the involvement of numerous computers or networks on the matching data connection. A network switch not include hubs or repeaters, as these devices do not consist of every type of logical processors. A network switch can support 10/100 Mbit/s or 10/100/1000 Mbit/s port transfer rates. It is likely to have numerous network switches operating at diverse speeds on the same network. On the other hand, this form of setup gives itself to bottlenecks and restricts the potential routes available for the flow of data. The network switch functions as the traffic management system within the network, directing data packets to the correct destination. These devices are used to link minor devices to the network as well as to make sure the full cost effectiveness and the ability to share properties. The characteristic to setup of a network switch is two computers, one printer, and a  wireless router. Every devices are connected to the network switch, and each item have to be clearly well-known and connection rules produced. When the setup is complete, every computer on the network, will use the similar printer. They also can transfer files to each other and anyone with a wireless card can access the network, print and transfer files. The network switch is intended to let the resources to be shared without decreasing performance. Network Cable Network cable is used to connect and transfer data among computers and a network. The best popular used types of network cable are the twisted pair, coaxial, Ethernet cross over, and fiber optic. The unshielded twisted pair (UTP) cable is used in several Ethernet networks. Each pair of wires that is housed inside of the lining cable is twisted into some additional rotations to prevent interfering from new devices on the network. The arrangement of this type of cable increases its consistency as well as it helps to reduce network disasters. Coaxial cable, or coax, is a different common type of network cable. It has a copper conductor in its center and a plastic coating serves as an insulator among the center conductor and also a metal shield. The cable is then protected with a coating. The thicker the coating which less pliable affords extra shield. Ethernet crossover cable is used to connect a computer network made up of two or more computers. This kind of network cable rejects the need for network switches or routers. The cable also let the computers to be connected with their network adaptors, such as the network interface card (NIC). Fiber optic network cables are used for networks that extent large distance. This category of cabling has some layers of protecting coating. It also transmits light as opposed to electrical signals like other cables. Furthermore, fiber optic is as well transmits data at high speeds and is therefore used in large network environments. As wireless networks become more and more popular, network cable is becoming less necessary. Still, many systems, especially large scale systems, continue to rely on network cables.

Essay --

Introduction Today, there are many different types of mental illnesses known throughout the world; i.e. bipolar disease, schizophrenia, paranoia, post-traumatic stress disorder, panic disorder, ect.; and many people who are able to diagnose such illnesses when symptoms are shown throughout a person [Webmd.com]. What about back in the 1600’s though, when such illnesses weren’t even known yet? In Shakespeare’s play Macbeth, for example, Macbeth showed many signs of what today would be diagnosed as symptoms of schizophrenia, but he had no idea, nor did anyone around him, they just thought he was going insane. What is schizophrenia one might ask? â€Å"Schizophrenia is a serious brain disorder that distorts the way a person thinks, acts, expresses emotions, perceives reality, and relates to others† (Joseph Goldberg). Symptoms Medline plus tells us that there are three major symptoms of the disorder; not being able to distinguish the difference between fantasy and reality, incoherent conversations, and withdrawal physically and emotionally. The most common and most well-known symptom of schizophrenia is when people cannot distinguish between what is real and what is not [Medlineplus.com]. Schizophrenics often suffer from delusions and hallucinations. A delusion is a belief that is not true and a hallucination is seeing, hearing, or sensing something that is not really there [Schizophrenia.com]. Macbeth is considered a schizophrenic because he possesses all of the symptoms said above. Background information According to Schizophrenia.com, schizophrenia can be traced to the old Pharaonic Egypt, as far back as the second millennium before Christ. At one point in history, all people who were considered "abnormal," whether due to mental illn... ... of her womb before she could actually give birth, Macbeth then comes out of his delusional state, and we realize that everything he did was because of the witches, and that they made him go crazy and become a schizophrenic (Shakespeare 213). Conclusion Apparitions, eternally bloody hands, and ghosts all sound like key elements to a nightmarish dream. Imagine not being able to tell if these things were real or just a figment of your imagination and you’ll know the position that Macbeth was in. In Shakespeare’s Macbeth, Macbeth show signs of what would today be diagnosed as symptoms of schizophrenia. He became detached from reality and spoke in crazy incoherent sentence fragments. Though they were not able to identify Macbeth’s mental illness during Shakespeare’s time, now after many years of research, it seems very certain that he was most likely a schizophrenic.

How Does Music Effect Human Emotions?

Music is any sound that is artistically created and presented. It is said that we need food so that our body may survive, but we need pleasure that so that our mind may survive. And no one gives you more pleasure and peace than music. When we listen to music, not only hear it, we establish a spiritual connection with any one who is a part of creation of music. All the time we hear any piece of music we feel that its creators are a part of us. It is one the most powerful medium that quite effortlessly is able to influence our emotions. Interpretation of music Those who listen to music can interpret a piece of music in different ways. Even it is a same piece of music, it will convey different message, a different sentiment and it is totally dependant upon the message that its creator wants to convey. A glimpse of the past It is a well known fact that right from time historical immemorial, people have been using music to increase the glory of war. Music has been used to motivate people to fight for their freedom and win wars as well. Almost every country has their own music/ anthem for their country and army. Music has its own merits Ask any doctor, consult any health expert, you will be told, music helps to increase concentration, memory. It is an essential aspect of curriculum in the schools. Practicing music helps to increase brain power. It increases their IQ level, reasoning and logical skills. So the next time someone says that they used to take some piano lessons and found it easier to concentrate in their studies, trust me, they are speaking the truth. A knowledge base named music Knowledge of music brings in a lot of awareness about people ,cultures , history and even societies. For example, if you want to learn Asian music, it will be impossible to do so without understanding the concerned culture.

Night †Devotion to God Essay

Under certain circumstances, one’s perspective towards their faith in God may change, which is demonstrated in the memoir Night. Wiesel’s initial devotion to God and his faith undergoes a radical transformation in the face of his horrendous experiences, resulting in apparently soils and cynical atheism, but his faith survives to some degree in spite of overwhelming odds, and in subsequent years move have revived enough to motivate this memoir. At the age of twelve, Wiesel began to question God and analyze the cabbala with his fellow friend Moche, and together there faith became stronger than before. Then, under circumstances, Moche was sent away, and returned as a different man. The motif of his eyes demonstrated his loss in the faith of God. He cried to the people to believe that the horrific experiences he said was true, but no one could pull themselves together to believe. Moche’s faith was gone, and that only made Wiesel’s faith stronger. Wiesel’s devotion never disappeared as he stated, â€Å"I continued to devote myself to my studies. By day, Talmud, at night, the cabbala† (18). Yet, his faith began to take a turn when the Germans took over the life of the Jews. He described his experiences as hell, describing that god was trying to say that hell wasn’t any worse than the experiences they were going through. Wiesel kept thinking of god, thanking him for every joyful moment that he came across. Wiesel’s faith became then weakened when he came across a rabbi. â€Å"Here came the Rabbi, his back bent, his face shaved, his pack on his back. His mere presence among the deportees added added a touch of unreality to the scene† (26), Wiesel faith weakened because seeing this rabbi left him in shock, making it so surreal. After the rabbi experience, Wiesel’s faith went downhill from there. When the night came along no one prayed, out of fear of the next day. Wiesel came across horrific experiences, making him question god. He saw babies and humans being burned, for no apparent reason. Angered, Wiesel came to a solution by stating â€Å"Why should i bless His name? † (42). At times, Wiesel’s faith was totally gone because he was angered towards how people were treated, and why God didn’t do anything about it. Wiesel’s relationship with God remained as he believed that God was out there, just hidden saying â€Å"I did not deny God’s existence, but I doubted His absolute justice. † (53). Then time passes and Wiesel’s relationship with God is then questioned when he is influenced by the people around him. One day he came across three victims being killed, and listening to to people saying â€Å"Where is He? † (72). Wiesel was also influenced by Akiba Drummer, as the motif in his eyes showed that he lost total faith in God. Wiesel no longer blessed God because he realized that there was no point of blessing God when he allowed so many horrid things to happen. Wiesel also stopped praying, since he had no time to do so. All this resulted to an extent of Wiesel being spiritually dead. Wiesel lost total faith and spirit in God, because of the horrid experiences he went through, which changed his perspective on certain things. After the concentration camp, Wiesel’s spirit and faith revive. Looking back at his experiences, as he writes his memoir, he realizes how harsh he was to God. Wiesel acted bitter towards God, as he lost faith, not because he chose to, it was because of the circumstances he was under. Wiesel’s faith and spirit was probably gained as he slowly began to realize that God had nothing to do with the repulsive experiences he went through. The reason he lost faith in God was because he needed someone to blame, someone to take his anger out to, and that was probably understood a while after he was rescued. Overall, Wiesel’s perspective towards faith in God changes, which is demonstrated in the memoir Night. To conclude, Wiesel’s initial devotion to God and his faith undergoes a radical transformation in the face of his horrendous experiences, resulting in apparently soils and cynical atheism, but his faith survives to some degree in spite of overwhelming odds, and in subsequent years move have revived enough to motivate this memoir. In certain situations, one’s relationship with God can take a change, for the better or worse.

galleries headed in the right direc Essays

1. Are museums/galleries headed in the right direc Essays 1. Are museums/galleries headed in the right direction by including the WEB into their "worlds" in different accessible ways? Is this a great way (the virtual museum ) to create accessibility to museums and art for the masses and classes? Why /why not? In my opinion, I believe that there are pros and cons to include the WEB into their "worlds". With having an entire museum/gallery at the tip of your fingers and in the comfort of your own home, this is a great and innovative idea for those who are unable to visit a museum/gallery due to medical conditions. Of course, by having this virtual museum/gallery accessible to everyone, it may also encourage the masses, who are completely capable of going to the museum, to simply stay home and view the artwork through a computer screen or cellular device rather than drive to the museum itself; "why go there when we can simply view in the palm of our hands". The masses are then simply satisfied with viewing the work on a screen rather than appreciating it in the museum itself. Many years ago, many viewers used to be astounded to stand in the presence of an artwork created by such magnificent artists. One would go to a museum with excitement, and leave with a sense of fulfillment, having the o pportunity to walk among such talented artists and spectacular artwork. The viewer seemed to be content and may have afterwards told friends or family, talking about the amazing experience. Being able to view these museums without having to get out of bed, we will soon come to depreciate the artwork and artists, and the enjoyment the museums once gave us. As mentioned before, this idea is indeed innovative and great for those who are unable to visit the museum, but only further encourages the rest of the masses, who are capable of going to a museum, to view the artwork in their own home. 2. You, the newest generation, has grown up on the internet and having accessibility to everything from your couch at home. Will the virtual museum decrease visitors to galleries and the sale of art? Will you stop going? Will it make museums and gallery visits obsolete? Growing up in this new generation, and having accessibility to the world wide web from my couch due to the technological advances that have rapidly occurred over the past decade, I believe that the idea of the virtual museum will definitely decrease visitors to galleries and the sale of art. As we have adapted to spending countless hours on the internet, and sitting in the same position for a great amount of time, the virtual museums will only encourage this behavior. As mentioned before, if they are able to access the museum and artwork from home, why bother to go there anyways. The sale of art will also decline due to the lack of people willing to pay for the artwork. Many people buy artwork after seeing it in front of them, and appreciating its beauty. They may find it quite appealing in a room in their house or possibly in a studio. With the lack of viewers at museums, and most people only seeing the art on a flat screen, there is a great chance that the sale of art will indeed d ecline significantly. I will continue to visit the museums because I would much rather be able to tell people that I have seen a famous artwork in person rather than telling them how I sat at home for hours on a virtual tour. It also gives the viewer a sense of satisfaction that they were able to witness the magnificent pieces live, and be able to see the texture in a 3D space, rather than a flat screen. Unfortunately, although some may want to continue to visit the museums, most will much rather stay in the comfort of their home. In turn, the museums and galleries may become obsolete due to the lack of visitors, which may also cause bankruptcy for the museums themselves. With no money, and little to no visitors to view the pieces, how can one expect to be able to continue to run a museum,

Psychopathological disorders Essay Example

Psychopathological disorders Essay Example Psychopathological disorders Essay Psychopathological disorders Essay Psychopathological disorders are not as common as other forms of illnesses. In this analysis, I will look at the nature of Dissociative identity disorder with special analysis to the movie Sybil.Dissociative identity disorder is a mental condition in which a person suffering from it experiences two or more different identities or personalities. In each of these personalities, the person usually has different patterns of perceiving information as well as interacting with the surrounding environment. In addition to this, the disorder involves abnormal memory loss. This abnormal memory loss is commonly referred as acute Dissociative disorderINTRODUCTION:Psychopathology is a medical or scientific term that refers to mental distresses or mental illnesses. In another context, the term can be used to refer to the manifestation of characteristic behaviours and or experiences that are usually indicative of psychological impairment or mental illnesses.In the context of this paper, I will look at one movie and or book that have a psychological theme. In addition, I will analyze the plot as well as the characteristic features of the disease and how it is analyzed or dramatized in the movie/book.ANALYSIS: BOOK/MOVIE REVIEW:SYBILThe movie Sybil analyzes the live of a person living with Dissociative Identity Disorder. The movie revolves around the true life of Shirley Ardell mason. Shirley was born in 1923 and died in 1998. She was a psychiatric patient, although she was a commercial artist. Shirley’s life was documented in a book by the name Sybil and later it was made a movie under the same name.The book was written by flora Schreiber and was published in 1973. The movie by the same name was adapted in 1976. The book and movie, in order to protect mason’s privacy and identity used the name Sybil Isabel Dorsett.The movie starred sally field (Sybil Dorsett), Joanne Woodward (Doctor Cornelia Wilbur), brad Davis (Richard Loomis) amongst others. The movie was direc ted by Daniel Petrie and was nominated for the globe awards.The plot outline of the movie reveals the true story of a beautiful young woman, Sybil Dorsett. Dorset’s child hood upbringing was so traumatizing, to a point that she developed more than twelve different personalities.For purposes of this paper I, will look analyze the movie and point out the key issues of Dissociative identity disorder (formerly multiple personality’s disorder). In this analysis, I will also look at the issue of whether the disorder really exists or it is just a medical creation.Shirley Mason was born and brought up in Dodge Centre, Minnesota. Within the early years of the 1950s, she was a teacher and a student at Columbia University. Mason had suffered for a long time from blackouts and emotional breakdowns. After this lengthy suffering, she finally entered psychotherapy under the guidance of Doctor Cornelia B. Wilbur. Doctor Wilbur was a Freudian psychiatrist. Shirley’s sessions und er Wilbur are the core basis of the book and movie.SYBIL:The book and movie made the implication that Shirley suffered from the Dissociative identity disorder as a result of several incidences of sexual abuses from her mother whom unfortunately is speculated to have been suffering from schizophrenia. Schizophrenia lies on axis one on clinical disorders. It is classified in the field of schizophrenia and other psychotic disorders.Schizophrenia is a psychiatric or medical diagnosis that describes a mental illness that is usually characterized by perception or expression of reality impairments. In most cases, schizophrenia manifests itself as aural hallucinations, bizarre or paranoid delusions. It also manifests itself in the form of disorganized thinking and speech coordination problems. There are no laboratory tests that are currently available to test for schizophrenia.Shirley’s parents were Mr. Walter Mason and Martha Hageman Mason. Shirley under went treatment for eleven ye ars after which she was well adjusted to live in the society. After the publication of the book, Shirley moved to Lexington.COMPARISON WITH OTHER PSYCHOPATHOLOGICAL ILLNESSES:Mental disorders vary depending on the time of diagnosis and or the cause of the disorder. This is why diagnostic systems like DSM are used in order to facilitate the level of communication between professionals as well as standardizing the criteria for diagnosis.In this movie Daniel Petrie takes us through real life aspects of personality disorders to their fullest. By introducing a mix of schizophrenia, suffered by Sybil’s mother and the Dissociative identity disorder that Sybil suffered.In addition to this Sally Field provides an awesome award-winning performance when she plays as Sybil, a disturbed woman who is suffering from a multiple personality disorder. Since Sybil was living alone in an apartment, she was tormented by numerous flashbacks and disturbing visions of her painful childhood. Since sh e was unable to live a normal life, Sybil met Doctor. Wilbur (Joanne Woodward).Dr Wilbur was a kind-hearted psychiatrist who ended up being extremely dedicated to help Sybil heal the wounds that were haunting her. Dr Wilbur was able to diagnose the 16 different personalities that Sybil was suffering from.CONCLUSION:The Dissociative identity disorder, that Shirley is believed to have suffered from is not very common. Regardless of this fact, issues arose after the publication of the book that indeed mason never suffered form the disorder; rather it was a deal between her and doctor Wilbur to seal a book deal.Although there are claims of sexual abuse these claims are rather hard to verify. Recent interviews with some of Shirley’s former friends have revealed that indeed she had an unusual relation with her mother. On the other side of the story if indeed Shirley’s mother was indeed schizophrenic, this then complicates issues further.On the other hand, Schizophrenia, as a mental disorder is very hard to detect. This is because not unless it is detected by people or the person suffering from it tells about it, it can never be detected. John Nash’s decision to deal with the disorder, with the help of his wife is a great motivation to people living with the disease. Although the diseases prevalence is quite small, it is necessary for the wider public to accept and help people living with the disorder.

A Critical Look at Death of a Salesman

A Critical Look at 'Death of a Salesman' Have you ever loved a rock band that had lots of great songs you cherished? But then the band’s hit single, the one everyone knows by heart, the one that gets all the airtime on the radio, isn’t a song you particularly admire? That’s the way I feel about Arthur Millers   Death of a Salesman. It’s his most famous play, yet I think it pales in comparison to many of his less popular dramas. Although it’s by no means a bad play, it certainly is overrated. Wheres the Suspense? Well, you have to admit, the title does give everything away. The other day, while I was reading Arthur Miller’s esteemed tragedy, my nine-year-old daughter asked me, â€Å"What are you reading?† I replied, Death of a Salesman, and then at her request I read a few pages to her. She stopped me and announced, â€Å"Daddy, this is the world’s most boring mystery.† I got a good chuckle out of that. Of course, it’s a drama, not a mystery. However, the  suspense is a vital component of tragedy. Sure, when we watch a tragedy, we fully anticipate death, destruction, and sadness by the play’s end. But how will the death occur? What will bring about the destruction of the protagonist? When I watched Macbeth for the first time, I guessed that it would conclude with Macbeth’s demise. But I had no idea as to what would be his undoing. After all, he and Lady Macbeth thought they’d never be â€Å"vanquished until Great Birnam wood to high Dunsinane Hill shall come against him.†Ã‚   How the heck is a forest going to turn against them?! Therein lies the suspense because, sure enough, the forest comes marching right up to their castle! The main character in  Death of a Salesman, Willy Loman, is an open book. We learn very early on in the play that his professional life is a failure. He’s the low-man on the totem pole, hence his last name, â€Å"Loman.† (Very clever, Mr. Miller!) Within the first fifteen minutes of the play, the audience learns that Willy is no longer capable of being a traveling salesman. We also learn that he is suicidal. Spoiler! Willy Loman kills himself at the end of the play. But well before the conclusion, it becomes clear that the protagonist is bent upon self-destruction. His decision to kill himself for the $20,000 insurance money comes as no surprise; the event is blatantly foreshadowed throughout much of the dialogue. The Loman Brothers I have a hard time believing in Willy Loman’s two sons. Happy: He is the perennially ignored son. He has a steady job and keeps promising his parents that he’s going to settle down and get married. But in reality, he’s never going far in business and plans to sleep around with as many floozies as possible. Biff: He’s more likable than Happy. He has been toiling on farms and ranches, working with his hands. Whenever he returns home for a visit, he and his father argue. Willy Loman wants him to make it big somehow. Yet, Biff can’t hold down a 9-to-5 job to save his life. Both brothers are in their mid-thirties. Yet, they act as though they are still boys. The play is set in the productive years following World War II. Did the athletic Lowman brothers fight in the war? It doesn’t seem like it. If they had, perhaps they would be completely different people. They don’t seem to have experienced much during the seventeen years since their high school days. Biff has been moping. Happy has been philandering. Well-developed characters possess more complexity. By leaps and bounds, the father is the best part of Arthur Miller’s play. Unlike many of the show’s flat characters, Willy Loman has depth. His past is a complicated tangle of regrets and undying hopes. Great actors such as Lee J. Cobb and Brian Dennehy have mesmerized audiences with their portrayals of this iconic salesman. Yes, the role is filled with powerful moments. But is Willy Loman truly a tragic figure? Willy Loman: Tragic Hero? Traditionally, tragic characters (such as Oedipus or Hamlet) were noble and heroic. They possessed a tragic flaw, usually a bad case of hubris. (Note: Hubris means excessive pride. Use the word hubris at cocktail parties and people will think you’re ever-so-smart! But dont let it go to your head!). In contrast, Willy Loman represents the common man. Arthur Miller felt that tragedy could be found in the life of ordinary people. While I certainly agree, I also believe that tragedy works best when the main character’s choices become whittled away, much like a masterful yet imperfect chess player who suddenly realizes he is out of moves. Willy Loman has options. He has a lot of opportunities. Arthur Miller seems to be criticizing the American Dream, claiming that Corporate America drains the life out of people and casts them away when they are no further use. Yet, Willy Loman’s successful neighbor continually offers him a job! Willy Loman declines the job without ever explaining why. He has a chance to pursue a new life, but he wont let himself give up his old, soured dreams. Instead of taking the decent paying job, he chooses suicide. At the play’s end, his loyal wife sits at his grave. She does not understand why Willy took his own life. Arthur Miller would claim that the dysfunctional values of American society killed him. However, I believe that Willy Loman suffered from senility. He exhibits many of the symptoms of Alzheimer’s. Why couldn’t his sons and his ever-attentive wife recognize his failing mental condition? It’s a mystery to me.

Marketing Communications Plan Essay Example | Topics and Well Written Essays - 4000 words

Marketing Communications Plan - Essay Example Sony Corporation is the electronics business unit that is responsible for the production and marketing of its video games consoles including the Sony PlayStation. The history of the PlayStation began in 1988 when Sony and Nintendo worked together on a product called the Super Disc. However, Sony and Nintendo parted company and the Super Disc was never launched by Nintendo. In 1991, Sony modified the Super Disk as part of its development of the first Sony PlayStation. Sony launched the long awaited PlayStation 3 in the USA in 2006 just two days before the launch of the Wii from Nintendo. These two new consoles proved to be immensely popular and most retail shops sold out of both within days. Soon afterwards both of the consoles appeared for resale in large numbers on the auction website eBay. The asking prices for some of these resale consoles were up to five times the original retail price. Microsoft's Xbox 360 console had a one-year lead in the market and enjoyed buoyant sales as a result. Nintendo's Wii positioned itself away from its main two competitors through the deployment of its ground-breaking motion-sensing controller (Cheng J, Mark Freeman-Aloiau M, Xin Guo, Pullen A. 2007) In 2In 2009, the PlayStation 3, helped by a $100 price cut, has outsold Nintendo's Wii console for the first time. Sales of the PlayStation 3 more than doubled to 491,800, while those of the Wii fell 33% to 462,800 (Satariano, A. 2009). The PlayStation 3 is expected to give a further boost to Sony's earnings in time for Christmas this year when the latest version of the blockbuster role-playing game for the PlayStation, 'Final Fantasy', is launched in December (iStockAnalyst, 2009). 2.0 Marketing Strategy 2.1 Positioning Strategy Sony uses the newest and greatest technology to appeal to their customers. The people who are most interested in staying up-to-date with the newest technology are usually men of the ages 15-30. To reach that market, they make games that are attractive to men of those ages; these games tend to be the shooters and high action games such as Kill Zone and God of War. However, they do make games for younger children; these games have a more adventure based game play such as Jak and Daxter and Crash Bandicoot. Beyond gaming, Sony also hopes to reach movie buffs with their high-definition movie playback thanks to Blu-ray technology. Blu-ray offers the latest advancement in movie entertainment experience. The detail of these movies is so good that you can literally see individual pores on people's faces. As you might expect, this means detail on everything is very high and movie buffs love this. 2.2 Product Strategy The PS3 offers the most advanced visuals and audio of any other game console and most computers. Hardcore gamers want their games to be more visually pleasing, and that is exactly what Sony has given them. They have changed very little about control setup except they have added some motion sensitivity (after they saw Nintendo unveil this feature in the Wii); this means that people who have played PS1 and/or PS2 won't have to learn how to hold and use the controller all over again. Also, there are a lot of classic games available for download via the Playstation Network (for a

Laura Essay Example | Topics and Well Written Essays - 2000 words

Laura - Essay Example Fast moving items are being recorded in the store managers’ hand-held computer in order to relay the message to the head office and its central design team. When it comes to production, Laura chose to print roughly 40% of its own fabric and produces 80% of its finished products. This production strategy allows Laura to be more flexible in responding to the sudden changes in fashion trend. Having an efficient logistics and Laura’s commitment to produce unique and fashionable clothing preferred by its target consumers throughout UK and Europe within a short span of 15 days makes the company able to keep up with the fast changing fashion trends. By continuously expanding its market distribution via increasing the number of its store outlets, telephone / mail order operation, and investing on online catalogue and ordering system including its practice of changing the store clothing designs every 4 weeks makes the annual sales increase over the The strength of Laura’s production system includes its ability to determine the trend of in-fashion clothing and its immediate response to the customers’ needs and wants by investing on a low cost in-house garment production that is responsible in printing its own fabrics, cutting, and sewing of garments just-in-time for delivery. The benefit of such production strategy is that it allows Laura to immediately respond to the customers’ constantly changing preferred fashion style within a short span of 15 days. The problem with this type of production strategy is the fact that its competitors are saving more money from outsourcing the production of garments in third world countries by bulk. In line with a much lower cost of production, Laura’s competitors are able to sell their product line at a much lower price. For this reason, Laura is not able to penetrate the lower end of the markets that are

Fasting Essay Example | Topics and Well Written Essays - 2500 words

Fasting - Essay Example From the early times, fasting has been criticized due its diverse scope of practice. In modern times, fasting in the form of a hunger strike has been employed as a political weapon. Fasting is a broad term that has become a focus over various controversies in the medical, spiritual, or political arena. Since time immemorial, controversies have come out on how to properly practice fasting. As an example, a religious practice that precludes one to do any sexual activity or refrain from eating a certain type of food during fasting has become a controversy that comes together with the proper practice of fasting. Looking back to the ancient times, several reasons are presented with regards to fasting. People fasted for purity, spiritual and physical. However, a controversy came out when some of those who fast seeking for spiritual purity end up being drained. This was discounted when majority of spiritual seeker felt energized after fasting. Moreover, this account was supported by the det ox dieters noting that they feel clearer, and from one point to another, felt some form of physical purity. This research paper will open up our horizon to better understand and unfold the complexity of fasting. In the context of medicine, fasting is defined as â€Å"voluntarily not eating food for varying lengths of time† (eNotes, 2008). For many conditions, fasting is used as a medical therapy, and is utilized for various chronic medical conditions such as allergies, anxiety, arthritis, asthma, depression, diabetes, headaches, heart disease, high cholesterol, low blood sugar, digestive disorders, mental illness, and obesity. In medicine, fasting is used to refer to the state that is achieved after digestion.

Income Statements Analysis Essay Example | Topics and Well Written Essays - 1750 words

Income Statements Analysis - Essay Example The â€Å"profit margin† is a good indicator of how a company is able to manage costs in its operations, for example, selling stock. It does not mean that if the total earnings of a company are increasing, then, the profit margin improves. When the costs increase at a greater rate than the sales, then the profit margin reduces. The opposite of this statement is also true. Note that net income is a perfect indicator of the financial health of a company. Net income also indicates the performance of the of the core business operations. The net income is calculated by deducting the expenses from the sales revenue (Fridson, Alvarez and Finance Pro, 2011). As stated earlier, the net profit margin is computed from the net income and sales’ values indicated in the income statement and thus it is also important to discuss the income statement in this section. The income statement mainly includes the items directly or indirectly related to the companies’ activities. The activities can be primary or secondary. Examples of the items included in the income statement may include incomes, revenue, cost of goods sold, tax expenses and gross profit. With these items, we can therefore, compute the net profit margins, which are necessary in determining the profitability of a company from its operations. Before comparing the profit margins for each company, it is important to look at how each company has prepared its income statement. Emaar Properties PJSC and Arabtec Holding PJSC have indicated the particular items included in their income statements. The other companies have indicated the specific items included in their income statements. For example, Emaar Properties’ income statement includes the cost of goods sold, revenue, gross profit, administrative cost profit before tax and tax expense. The company has eliminated other, operating expenses, other operating income,

The Importance of Sex Education in Todays Schools Essay Example for Free

The Importance of Sex Education in Todays Schools Essay What did you learn about in school today honey? Oh, we did some proofs in Geometry, practiced past tense verbs in Spanish, and learned about sexually transmitted diseases in Health class. Suddenly, all goes silent, and the subject is quickly changed to something else. One of the most controversial issues facing todays schools is whether or not sexual education, or sex ed, should continue to be taught to children. On one hand, some argue that it should, because children need to be properly educated on this topic and the potential consequences that can result from it. However, many others oppose this viewpoint, arguing that sex ed is a personal subject for parents to discuss with their children, and therefore does not belong in an academic setting. While both of these viewpoints have their strengths as well as their limitations, it is extremely important for sex ed to continue to be taught in todays schools. Not only will students be properly educated on how to prevent negative sexual outcomes, such as sexually transmitted diseases (STDs) and unintended pregnancies, but also on the wide range of topics related to sexual health, such as communication, relationships, and decision-making. Overall, sex education has both physical as well as emotional benefits for school-aged children. Of course, there are several reasonable objections to sexuality education curriculum being taught in todays schools. First, it is argued that  sexuality is an inappropriate topic to be taught in schools, for schools are a place to learn typical academic subjects such as Math, Science, or English. In addition, those who are against sex ed assert that sex is a personal matter and should only be taught to children by their parents. In other words, it is the parents responsibility to provide sexuality education for their own children (Goldman 5). This would be a reasonable point to make. After all, parents are the first and most readily accessible of all the teachers from whom children learn (Goldman 6). Further, children consistently report that they want to receive information from their parents regarding sex (Goldman 6), suggesting that they would rather learn about sexual activity from their parents than from teachers. Finally, opponents of sexuality education curriculum argue that teaching this topic in schools essentially condones teenage sex, and thus will result in more teens engaging in sexual activity. However, these opposing positions have their limitations. Researchers point out that sex ed is after all, an academic subject, so it is appropriate that it is included in schools curriculum (Hamilton, Sanders, and Anderman 3). Sex ed is not a class taught on its own, but rather a component of schools health classes. The problem is, people mistakenly believe that sex ed only refers to sexual behavior, such as sexual intercourse, and not the full array of topics that comprise sexuality (Implementing, par. 4). These topics include information on:  abstinence, body image, contraception, gender, human growth and development, human reproduction, pregnancy, relationships, safer sex (prevention of sexually transmitted infections), sexual attitudes and values, sexual anatomy and physiology, sexual behavior, sexual health, sexual orientation, and sexual pleasure. (Implementing, par. 4) From this information, it can be concluded that sex ed does not just discuss sexual activity as critics claim. Rather, it teaches students about several important life topics regarding sexual health and human relationships. The argument that parents should be the sole educators on sexuality has its  limitations as well. The fact is, not all parents are talking to their children about sex. A nationally representative survey commissioned by the Planned Parenthood Federation of America (PPFA) and the Center for Latino Adolescent and Family Health (CLAFH) revealed that 57% of parents either feel only slightly comfortable or uncomfortable talking to their children about sex and sexual health (Parents, par. 6). Also, additional research has shown that many parents do not provide relevant, timely, developmentally appropriate or even enough sexuality education for their own children, and the education they do provide is perceived by their children as infrequent and of poor quality (Goldman 6). So even if parents are talking to their children about sex, they may not be giving their children a proper or complete education. A study conducted on the salience and utility of school sexuality education for young men found that for most young men, school sex education appeared to be the only substantive source of information they had received on sexual matters (Goldman 8). Finally, if parents really feel that they are the best educators regarding sexuality and do not want schools teaching their children this topic, they have the right to pull their children out of the program. According to the California Department of Education, the law recognizes that parents have the ultimate responsibility for teaching their children about human sexuality and may choose to withdraw their children from this instruction (California Department of Education #15). Schools are required to notify parents at the beginning of the school year about planned comprehensive sexual health education and HIV/AIDS prevention education and give parents the opportunity to review materials as well as the opportunity to request in writing that their child not participate in the instruction (California Department of Education #15). In closing, sexual education is a vital component in todays academic curriculum, for it may be the only source from which some children receive accurate information regarding sexual health. Finally, there is the false belief that providing comprehensive sexual education in schools endorses sexual activity and will lead to more teenagers having sex. However, research shows just the opposite: knowledge of sexuality is much more likely to lead to informed decision making, delayed sexual intercourse, responsible interpersonal behavior, and  self-protection strategies (Goldman 7). In addition, a study that examined sex education in California public schools revealed that curriculum-based, comprehensive sexuality education, which involves instruction that includes a focus on abstinence, as well as inclusive information about contraception and sexually transmitted diseases, has been shown to delay sexual activity (Combellick and Brindis 3). The belief that teaching children about sexual education endorses premarital sex is erroneous because school-based sex education has been shown to delay, rather than hasten, the onset of sexual activity (Goldman 7). It can now be seen tha t these three common objections to sexual education curriculum being included in todays schools have their limitations. Comprehensive sexual education programs can greatly benefit school-aged children. With this curriculum in place, children will receive a complete education on the risks associated with sex, such as sexually transmitted diseases (STDs) and unintentional pregnancies, and how to avoid these outcomes. This knowledge has been shown to decrease the number of unintentional teenage pregnancies as well as STDs. One study revealed that teenagers who received a comprehensive sex education were significantly less likely to report a teen pregnancy compared to those who received no sex education (Kohler, Manhart, and Lafferty). According to the Sexuality Information and Education Council of the United States (SIECUS), this likelihood is about 50 percent lower, a tremendous finding. In addition, school-based sex education efficiently reduces the incidence of negative sexual outcomes as well as increases teenagers intentions to adopt safer sex behaviors (Kumar, Lim, Langford, Seabrook, Speechley, and Linch; Goldman 7). Thus, sexual education programs can play a tremendous role in reducing the number of teenage pregnancies and STD cases. In addition, sex education programs are necessary in todays schools because children are undergoing sexual development at much younger ages than in previous generations. Over the past decade or so, the age at which children start puberty has gone down considerably. According to WebMD.com, American boys are starting puberty at an average age of ten; two years earlier than the average age from twenty years ago (DeNoon par. 1). Similarly, girls tend  to start puberty around age eleven, but some can start as young as eight or nine years old (Watson). With the onset of puberty, children undergo many hormonal and physical changes that they may not fully understand without proper instruction. Furthermore, adolescence, defined as the ages between 10 and 19 years (Goldman 4), is a crucial stage in sexual development as well as for learning about healthy sexuality (Kumar; Goldman 20). In Goldmans study, surveyed children viewed puberty and its implications for the maturation of human development as a major part of their body, self-identity, and social and interpersonal norms (20). In other words, children are aware of the important role puberty plays in their physical, emotional, and social development. Thus, sexual education should remain a part of todays schools curriculum, so children will continue to be fully educated on the rapid physical and emotional changes they are undergoing. However, as is the case with all arguments, this position has its limitations. Students being educated about sexuality at school may feel like they do not need to discuss this topic with their parents. As a result, sexual education programs could indirectly discourage students from talking to their parents about sex. Additionally, even if schools are teaching comprehensive sexual education programs, some students may not retain all of the information they receive. One study found that a majority of the surveyed adolescents demonstrated significant gaps in sexual knowledge even though they had successfully completed their high school sex ed requirements (Kumar et al.). Finally, despite the fact that 22 states require public schools to teach sex ed, the United States still has the highest teen birth rate in the industrialized world: three out of ten girls in the U.S. will become pregnant at least once before their 20th birthday (State). In addition, about nine million cases of STDs occur among teenagers and young adults in the United States every year (Weinstock) even though 33 states require HIV/AIDS instruction in schools (State). However, these limitations do not take into account that 28 U.S. states do not require sexual education to be taught in public schools. As a result, not all students are receiving a complete education on sexuality, which includes instruction on how to prevent pregnancies and STDs. After all, only  about five percent of young people in the United States get a complete and comprehensive sexuality education (Goldman 19). In addition, only 14% of school districts in the U.S. permit comprehensive sexuality education to be offered to students (Goldman 15). Therefore, the high number of teen pregnancies and STD cases in the U.S. could be attributed to a lack of comprehensive sex education programs, not an overabundance of them. Overall, sexual education programs are an integral component of school-aged childrens academic curriculum, as much as the public has come to realize. More than 90% of parents of junior high and high school students believe that it is important for sex ed to be taught in the classroom (Facts #10). Moreover, teachers, parents, and students all agree that schools should provide quality sex ed, including knowledge, skills, and values, that will enable school-aged children to make timely choices and thought-out decisions for themselves (Goldman 20). Thus, it can be seen that sex education is already a widely supported component of elementary and secondary academic curriculum. Finally, sex education should continue to be taught in schools because it educates children on many important life skills. Sexuality has several different topics associated with it, such as human development, relationships, communication and decision making (Siecus par. 5.). When people think of sex ed, they generally do not think of these life skills. However, sex involves numerous life decisions, from choosing to abstain to choosing a birth control method. In addition, communication and relationships are an integral part of sexuality, because it is a union that involves two separate people. Plus, students who received a comprehensive sex education were more likely to report having better communication with their parents (Hamilton 5). Due to this wide array of topics covered, it is no wonder that high school sexual education classes received the highest average rating of usefulness among all listed sources (Kumar et al.). Sex education programs truly benefit todays school-age children in countless ways. There is no doubt that sex education in todays schools is a controversial  issue, however, it must continue to be taught. Children who do not receive proper instruction on this topic at home need a place where they can receive accurate information regarding sexuality. Furthermore, this academic subject will help students learn the skills necessary to make informed decisions regarding their sexual health and avoid negative sexual outcomes. Finally, it is so important for sex education to be taught in schools so that developing children can learn about their changing bodies as well as numerous important life skills. Sex education should no longer be viewed as an inappropriate topic to be taught in schools, but rather as an essential component of school-aged childrens education.

Advantages And Disadvantages To Using Indexes Computer Science Essay

Advantages And Disadvantages To Using Indexes Computer Science Essay Put simply, database indexes help speed up retrieval of data. The other great benefit of indexes is that your server doesnt have to work as hard to get the data. They are much the same as book indexes, providing the database with quick jump points on where to find the full reference (or to find the database row). There are both advantages and disadvantages to using indexes,however. One disadvantage is they can take up quite a bit of space check a textbook or reference guide and youll see it takes quite a few pages to include those page references. Another disadvantage is using too many indexes can actually slow your database down. Thinking of a book again, imagine if every the, and or at was included in the index. That would stop the index being useful the index becomes as big as the text! On top of that, each time a page or database row is updated or removed, the reference or index also has to be updated. So indexes speed up finding data, but slow down inserting, updating or deleting data. Some fields are automatically indexed. A primary key or a field marked as unique for example an email address, a userid or a social security number are automatically indexed so the database can quickly check to make sure that youre not going to introduce bad data. So when should a database field be indexed? The general rule is anything that is used to limit the number of results youre trying to find. Its hard to generalise so well look at some specific but common examples. Note the database tables shown below are used as an example only and will not necessarily be the best setup for your particular needs. In a database table that looks like this: Note: The SQL code shown below works with both MySQL and PostgreSQL databases. CREATE TABLE subscribers ( subscriberid INT PRIMARY KEY, emailaddress VARCHAR(255), firstname VARCHAR(255), lastname VARCHAR(255) ); if we want to quickly find an email address, we create an index on the emailaddress field: CREATE INDEX subscriber_email ON subscribers(emailaddress); and any time we want to find an email address: SELECT firstname, lastname FROM subscribers WHERE emailaddress=[emailprotected]; it will be quite quick to find! Another reason for creating indexes is for tables that reference other tables. For example, in a CMS you might have a news table that looks something like this: CREATE TABLE newsitem ( newsid INT PRIMARY KEY, newstitle VARCHAR(255), newscontent TEXT, authorid INT, newsdate TIMESTAMP ); and another table for authors: CREATE TABLE authors ( authorid INT PRIMARY KEY, username VARCHAR(255), firstname VARCHAR(255), lastname VARCHAR(255) ); A query like this: SELECT newstitle, firstname, lastname FROM newsitem n, authors a WHERE n.authorid=a.authorid; will be take advantage of an index on the newsitem authorid: CREATE INDEX newsitem_authorid ON newsitem(authorid); This allows the database to very quickly match the records from the newsitem table to the authors table. In database terminology this is called a table join you should index any fields involved in a table join like this. Since the authorid in the authors table is a primary key, it is already indexed. The same goes for the newsid in the news table, so we dont need to look at those cases. On a side note, table aliases make things a lot easier to see whats happening. Using newsitem n and authors a means we dont have to write: SELECT newstitle, firstname, lastname FROM newsitem, authors WHERE newsitem.authorid=authors.authorid; for more complicated queries where more tables are referenced this can be extremely helpful and make things really easy to follow. In a more complicated example, a news item could exist in multiple categories, so in a design like this: CREATE TABLE newsitem ( newsid INT PRIMARY KEY, newstitle VARCHAR(255), newscontent TEXT, authorid INT, newsdate TIMESTAMP ); CREATE TABLE newsitem_categories ( newsid INT, categoryid INT ); CREATE TABLE categories ( categoryid INT PRIMARY KEY, categoryname VARCHAR(255) ); This query: SELECT n.newstitle, c.categoryname FROM categories c, newsitem_categories nc, newsitem n WHERE c.categoryid=nc.categoryid AND nc.newsid=n.newsid; will show all category names and newstitles for each category. To make this particular query fast we need to check we have an index on: newsitem newsid newsitem_categories newsid newsitem_categories categoryid categories categoryid Note: Because the newsitem newsid and the categories categoryid fields are primary keys, they already have indexes. We need to check there are indexes on the join table newsitem_categories This will do it: CREATE INDEX newscat_news ON newsitem_categories(newsid); CREATE INDEX newscat_cats ON newsitem_categories(categoryid); We could create an index like this: CREATE INDEX news_cats ON newsitem_categories(newsid, categoryid); However, doing this limits some ways the index can be used. A query against the table that uses both newsid and categoryid will be able to use this index. A query against the table that only gets the newsid will be able to use the index. A query against that table that only gets the categoryid will not be able to use the index. For a table like this: CREATE TABLE example ( a int, b int, c int ); With this index: CREATE INDEX example_index ON example(a,b,c); It will be used when you check against a. It will be used when you check against a and b. It will be used when you check against a, b and c. It will not be used if you check against b and c, or if you only check b or you only check c. It will be used when you check against a and c but only for the a column it wont be used to check the c column as well. A query against a OR b like this: SELECT a,b,c FROM example where a=1 OR b=2; Will only be able to use the index to check the a column as well it wont be able to use it to check the b column. Multi-column indexes have quite specific uses, so check their use carefully. Now that weve seen when we should use indexes, lets look at when we shouldnt use them. They can actually slow down your database (some databases may actually choose to ignore the index if theres no reason to use it). A table like this: CREATE TABLE news ( newsid INT PRIMARY KEY, newstitle VARCHAR(255), newscontent TEXT, active CHAR(1), featured CHAR(1), newsdate TIMESTAMP ); looks pretty standard. The active field tells us whether the news item is active and ready to be viewed on the site. So should we should create an index on this field for a query like this? SELECT newsid, newstitle FROM news WHERE active=1; No, we shouldnt. If most of your content is live, this index will take up extra space and slow the query down because almost all of the fields match this criteria. Imagine 500 news items in the database with 495 being active. Its quicker to eliminate the ones that arent active than it is to list all of the active ones (if you do have an index on the active field, some databases will choose to ignore it anyway because it will slow the query down). The featured field tells us whether the news item should feature on the front page. S hould we index this field? Yes. Most of our content is not featured, so an index on the featured column will be quite useful. Other examples of when to index a field include if youre going to order by it in a query. To get the most recent news items, we do a query like this: SELECT newtitle, newscontent FROM news ORDER BY newsdate DESC; Creating an index on newsdate will allow the database to quickly sort the results so it can fetch the items in the right order. Indexing can be a bit tricky to get right, however there are tools available for each database to help you work out if its working as it should.

A Comparison of Practical and Principled Nonviolent Action Theories Ess

A Comparison of Practical and Principled Nonviolent Action Theories Introduction The phrase "nonviolent action" brings to mind a wide variety of sometimes conflicting images. The image of a Chinese student at Tiananmen Square standing in the way of a tank was portrayed around the world, along with the stories of those who were shot and run over by those tanks. Indian participants pressed forward undauntedly in columns and then in groups to the salt depot at Dharasana while being beaten back with clubs by police forces who were infuriated by the nonresistance of the people. Individual Danes sneaked onto the Nazi occupied airfields at night to sabotage their own planes to prevent them from being used against the Allies and the Danish people. Polish workers during the Solidarity movement refused to vote even though it was illegal and succeeded in preventing the election of unwanted single ticket politicians. Though widely varied, these images all accurately represent nonviolent social change movements of the last century. Two theories have dominated the recorded history of the nonviolent social change movement as motivation for keeping the movements nonviolent: pragmatism and principle. A pragmatic approach has led to what is called practical nonviolent action--action based either on the lack of violent options or on the direct efficiency of nonviolence. Action based on a theory of moral, ethical, or religious principles is known as principled nonviolent action. Both theories have motivated successful campaigns and both have spawned actions in which the goals of the movement were not accomplished. A number of authors in recent years have carefully examined and articulated both theories along with the case studies of moveme... ... 1989. Douglas, James.
