Assignment #5 - Research Paper Example that have to be applied by the participants to score positively in all other succeeding levels, which concern with changes in behavior, results, and ROI (Phillips, 1997, p.43). In calculating Cost/Benefit Ratio, the total benefits are divided by the cost while for assessing ROI formula, â€Å"the costs are subtracted from the total benefits to produce the net benefits, which are then divided by the costs" (Phillips, 1997, p.43). Thus ROI is the Cost/Benefit Ratio calculation that is done by taking not the total benefits but the net benefits, which is calculated by subtracting total costs from the total benefits. The ROI formula takes into account the tangible costs and benefits alone while Cost/Benefit Ratio incorporates both tangible and intangible costs and benefits, thereby being more comprehensive (Phillips, 1997, p.73). The most often used validity testing approach is content validity just because it is more â€Å"cost-effective† (Phillips, 1997, p.90). This is also so because the â€Å"successful mastery of program content† as is shown by this validity test will be â€Å"related to improved job performance† (Phillips, 1997, p.280). Control groups, customer input and forecasting model are three methods that can be used to isolate the effects of an HRD training program (Phillips, 1997, p.105, 197, 70). In the control group method, it is the â€Å"results of the experimental group, when compared to the control group† that show the â€Å"impact of the HRD program† (Phillips, 1997, p.105). In a training program that is intended to ensure that customers come back to the company, customer input could be a valuable strategy to isolate the effects (Phillips, 1997, p.197). In a situation where â€Å"input and output variables are known†, it is easy to predict the effects out of logical reasoning and common sense and hence the forecasting model will be an effective method to isolate effects (Phillips, 1997, p.70). It is for consistency of data that an evaluator should gather

Technical definition and description - Essay Example According to a brief definition suggested by Chen, Hassan, and Yu; â€Å"a fuel cell is an electrochemical cell that converts chemical energy from a fuel into electrical energy† (58). A fuel cell generates electricity through chemical reactions between a fuel and an oxidant in the presence of an electrolyte. A notable feature of the fuel cell is that it can operate continuously as long as proper reactant and oxidant flows are maintained. Fuel cells generate nonpolluting power, and they perform outstandingly in terms of efficiency. Since fuel cell have no moving parts, they product little noise. Fuel cells have been serving the energy needs of spacecrafts since 1960s on the strength of its ability to operate uninterruptedly. In spite of the recent advancements in the technology, fuel cells are still increasingly used in power generating plants and exhaust-free automobiles. The major difference between a batter and a fuel cell is that the former has a fixed supply of energy whereas the latter can generate energy continuously as long as the fuel is supplied. Like a battery, a fuel cell is made up of a large number of individual cells that are collectively called a fuel cell stack. All these individual cells are comprised of an anode, a cathode, and an electrolyte. In a fuel cell, anode is generally made of platinum because it can better catalyze the reaction ionizing the gas. When a hydrogen-rich fuel like renewable biogas or clean natural gas is supplied to the fuel cell stack, ‘it reacts with oxygen electrochemically to produce electric power, heat, and water’ (How do fuel cells work). Although different types of fuel cells operate a bit differently, basically they all work based on the same process. In a fuel cell, hydrogen atoms enter the anode where their electrons are stripped off through a chemical reaction. Thus, the hydrogen atoms become ionized, and resultantly they carry a positive charge. At the same time, the negatively

Computer Networking and Management - Case Study Example figurations at the data center core switch enable functional areas within each department to operate as independent LANs regardless of their physical locations. Internet-enabled Client Applications The following typical applications are allowed by the security management team to access the Internet: 1. Web browsers (IE 7). 2. Email client (Outlook 2007). 3. Skype client; used for voice chat, instant messaging, video conferencing, and low-cost Internet telephony. These applications were found essential to facilitate immediate contact and collaboration across to other universities and research institutions. No other network applications are allowed access to the Internet. The above Internet clients operate at designated TCP ports, which are open but monitored and occasionally audited though the firewall, to ensure compliance with security and IT access policy set forth by the campus network management. Any other applications requiring access to university wide intranet resources achieve that through a web interface and therefore do not require having arbitrary ports open. Figure : screen shot of web browser, email client, and IM/IPT clients Servers Servers, central security appliances, and edge network appliances are all housed in a secure one-level data center, located within the same campus area. Servers are connected to the main access router via a 10Gbps optical Ethernet. Table 2 illustrates the server distribution, platforms, and functionality.

Ping Sweeps and Port Scans Essay Example for Free

Ping Sweeps and Port Scans Essay This report is to provide insight on nefarious computer activities called ping sweeps and port scans as a request from management. I will identify them, explain what they are use for, how they are used and how to stop them from attacking a network. Finally I will discuss how they can be eliminated as security risk. The information in this report is designed to increase the understanding and knowledge of these two activities so that this company’s IT department will be in a better position to recognize them and block potential attacks from their use. According to S. Branch (2012), in his article What is a Ping Sweep he says â€Å"A ping sweep, also called an Internet Control Message Protocol (ICMP) sweep, is a diagnostic technique used in computing to see what range of (IP) addresses are in use by live host, which are usually computers†. Ping sweeps are not unusual, they are often used by administrators in diagnosing network issues; however, hackers also use ping sweeps to find active computers so they will know where to concentrate their attacks. This can become a serious security breach for an unprepared network. Hackers send not one ping but many packets at the same time. This tends to slow down a network. When the hackers ping sweep finds an active computer it can send request for confidential information. There is no reason to be alarmed by ping sweeps because the solution for stopping them is very simple. The system administrator only need to disable ICMP packets and if the system administrator wants to do a ping sweep, just enable the ICMP packets temporarily. According to S. Branch (2012), â€Å"ping sweeps are older and slower technology, and are not in use as much as in the past†. A port scan attack is a popular reconnaissance technique that attackers use to discover services they can break into according to Yahoo Answers (2007), Author unknown. Yahoo Answers states that â€Å"All machines connected to a network run many services that use TCP or UDP ports and there are more than 6000 defined ports available. Normally port scan does not make direct damage just by port scanning. Potentially a port scan helps the attacker find which ports are available to launch various attacks†. A port scan sends a message  to each port one at a time. The response received back indicates whether the port is being used and if so, the port will be probed for weakness. TCP ports are the most attacked ports because they are connected oriented and give good feedback to the attacker. The most frequent port scan attacks to look for are: Stealth Scan, which is design to be undetected by auditing tools, SOCKS, which allows multiple machines to share a common internet connection, easy access when not configured correctly. Bounce Scans, are systems that they can bounce their attacks through. These systems are FTP server, Email server, HTTP Proxy, Finger and others. These all have vulnerabilities to do bounce scans. They also use UDP ports to find open ports, but it is not often used because it is easily blocked. Port Scan attacks can be reduced or completely solved by deploying Firewalls at critical locations of a network to filter unwanted traffic. There is also Port Scan Attack Detectors (PSAD) on the market for free use. In the fast developing world of computer technologies there will always be hackers and other types looking for ways to still. In the earlier days of computer technology they were not much of a problem if any. Today programmers and system builders program and build their goods with hackers and others in mind. Many security features are built in and other features are discussed and put in place at the beginning of the project. Nothing is foolproof, but if there is a way for them to get in, there is a way to keep them out. References Author unknown. (2007).

Counselling Psychotherapy Theories Applied | Case Study

Counselling Psychotherapy Theories Applied | Case Study Case Study: Vignette II Bella. H. T. Lam Theories Systems in Counselling Psychotherapy My client Scott, who is a 19 years old male, have lost his father for nine months because of the lung cancer. The major problem revealed by his mum was he had become quite and stayed aloof when he is at home. During the previous sessions, he was just looking downward and fidgeting with his figures. Brief answers are always appeared when I am asking some open questions. However, he thought he need help and agreed to have change when I told to close the session. To begin with, I may like to analyze some of his behaviors so as to develop an effective section for him. From his mother, I knew that he has become quite and aloof after his father died this maybe one of the action, which he was trying to avoid his real feeling. Also, it might have a chance that Scoff does not know how to cope with his own feeling about his father’s death. Moreover, in between our conversation he usually gives me brief answers or sometimes remains silent in account to the mistrust of people or some energy blockage suggested by Gestalt, this turned out he does not want to answer question, sharing his feeling or he does not know how to answer. Without eye contact and fidgeting finger were also the gestures related to his mistrust or lose of love and belongingness needs. Therefore, in the coming session I hope to build a trust-worthy relationship with Scott so as to allow him to share the real feeling with me. Furthermore, helping Scott to face, express, aware a nd cope with his feeling are also my targets. Progressive Muscle Relaxation I would choose the progressive muscle relaxation to start with the counselling session. As Scott mentioned that he got headache sometimes since his father was died on the previous session. I think temporary headache was one of the psychosomatic symptom. The process of relaxing muscle and mental tension in the progressive muscle relaxation may help client to cope with chronic pain and the frequency of migraine attacks which is related to the stress or anxiety.(Ferguson Sgambati , 2008) Despite, Scott does not feel stress or anxiety, he behaves silent and aloof when he is at home might in account to his stress or anxiety. In the section, I may give instructions to Scott to teach him relax. Then, ask Scott to breathe deeply and regularly so as to relax his muscle. Try to feel the muscle when they are tensioned. Then he would asked to relax his muscle from the head then neck and shoulder to the back until the lower limbs. During the time of relaxation he is asked to try getting rid of the mental problem and feel the contrast between relax mode and tension mode. He could learn to become relax if he keep practicing this action daily. And this would become the habitual behavior in his daily life. Progressive muscle relaxation could be use with any other approach easily and can practice daily by the client. This might help Scott to learn how to relax and improve his daily living when he is feeling stress or anxiety. This practice not only relaxing his muscle but also his mental. ( Davis,1980) Expressive Art Therapy The next stage I would like to use expressive art therapy so as to help Scott to express his feeling. Since Scott can only answer brief answer when I asked open question I suggest that he did not know how to express his owns thing verbally or it might because he did not aware his owns’ problems so he cannot express himself when I am asking him questions. While expressive art therapy is found by Natalie Rogers, it uses various artistic forms, for example, creating movement, writing a journal, playing music as a media to help people to express his emotion. N, Roger explained that â€Å"This is a multimodal approach integrating mind, body, emotion and inner spiritual resources.†(N, Rogers, 1993,) Thereby, expressive art therapy let people to look at its unconscious mind and express some unknown or new information. â€Å"This is also a self-discovery and healing process.† (N, Rogers, 1993)This may allowed Scott to express his emotion in order to have more understandi ng about his unconscious mind. In this section, I would prepare some percussion instruments to Scott, allowing him to express his feeling by music improvisation. I would ask him to think of some scenarios and try to use different instruments to represent or reflect that scenario. This may help him to aware and express his emotion himself and give me further information about his emotion. I think this is a suitable way for Scott as he did not answer a open question easily, using a different way like playing music maybe give him another way to express himself. Nevertheless, Person-Centered therapy is the key features of Expressive Art therapy while they are also emphasis the relationships between the client and therapist. (N, Rogers, 1993) Therefore, I would like to build a trust -worthy relationship with my client using the knowledge of Person-centered therapy before I started the Expressive Art Therapy. Person-Centred Therapy Other than not knowing how to express his own emotion, Scott answering question in a very brief way might also because he does not want to share his real feeling. According to the Carl Roger’s Person-centered Therapy, relationship between client and therapist was very significant for the treatment. As if the clients feel that his feelings are understood by the counselor might support the clients’ desire to change. (Roger, 1961) The Person-centered Therapy suggested the three main ways to develop a good relationships with the client. Including Congruence, Unconditional Positive Regard and Empathic Understanding. (Cain, 2010 ) Being congruence means that the therapist should express truly with his emotion, attitudes, thoughts when they are interacting with the client. Providing unconditional positive regard means is caring the client as a true person, while the caring without any criteria or judgments. (Koldon, Klein, Wang, Austin,2011) According to Rogers’s (1961) research, the more caring the clients got, the more success of the therapy would be. While empathic understanding is to share the subjective view by the experience’s that the client’s mentioned. After this Scott can identify his own goal by himself. So as to provide these three conditions, I would like to chat with Scott with more caring, sometimes give some restatements of what he just said to show my empathic understanding, express my true feeling and attitude when we are chatting. Also, giving a sense to him that I would support him no matter what he decide or think. After this kind of interaction I might build a better or trust-worthy relationship with Scott and give the love and belongingness needs that enable him to share his real feeling to me and he will tell me more rather than just answer me a short answer or refuses to answer me. Moreover, the rarely eye contact with counselor may deal to his unsafety feeling. During this Personal centered therapy, I would provide him a safe environment which can let him feel safe and willing to have eye contact with other and less fidgeting. The final aim of this treatment is to allow him to express himself, trust himself by providing him concern and care, I could act as a facilitato r to allow him to be independent and integration which leads him able to cope with his life’s issue like the dilemma of his father’s death. In addition, this therapy is suitable for people who is open and ready for change since Scott agree to see the counselor and admitted he need helps reflect that he is ready and open to have some changes.(Corey, 2013) However, Person-centered therapy was an unstructured therapy which is difficult to estimate the duration needs for this treatment. The only way is to recognize how the client’s know about himself and helping him to come up with his own plan. Therefore I would like to spend more time in this treatment before moving to the next part. Gestalt Therapy The next treatment I would like to use is the Gestalt therapy. Although we have used the Expressive Art therapy so as to bring up Scott awareness to himself, it might not enough because the art therapy more focuses on expressing the emotion and feeling. To further bring up his awareness of his own feeling I would like to assist him to attain greater awareness which includes knowing the environment, oneself also make contact with their awareness by using the Gestalt therapy.(Ploster Ploster, 1973) Apart from expressing his emotion, aware and face his own emotion is also my concern. In Gestalt therapy, it mainly focuses on where the energy used or blocked, the here and now which allow client to fully experience the â€Å"now† also the unfinished business which the figure is lined inside the ground and not completely solved and come with some unexpressed feeling.(Ploster, 1973) While blocking energy is another form of defense behavior suggested by Gestalt. In Scott cases, looking away from counselor when they are chatting, mention only a few is also the behavior of blocking energy. (Corey, 2013)When Scott staying at home quietly and aloof are examples of that he cannot express his own feeling and cause unfinished business. His father has died for nine months but he changed his behavior started from his father death to now that represent Scott is still struggling with the past experiences as Gestalt therapist recognized that the past would come to the present’s moment is usually the lack of completion of the past experience.(Corey, 2013 ) While in this treatment I would encourage Scott to experiences his own blocking energy gesture and allow him to know what is he struggling and accept it. Also trying to bring his feeling from the past to present and know that he can make a change of situation. I would choose the Reversal exercise and Exaggeration exercise for Scott. For reversal exercise, I would ask him try to look at me and stop fidgeting with his figure for a minute when we are chatting, to let him to accept what he is doing. After that, I would ask him to stay silent for longer time which to exaggerate his behavior. (Feder Frew, 2008) From this behavior he can try to interpret his inner feeling when he is keeping silent. The gestalt therapy have much explanation about the importance human’s gesture and language which would be suitable for Scott which have more gesture and less words to aware his feeling via body languages. Conclusion In this session there might be used four treatment, The progressive muscle relaxation, Person-centred therapy, Expressive art therapy and the Gestalt therapy. The progressive muscle relaxation might want to help the client improve his psychosomatic illness like headache. While the person-centred therapy is aim at building a trust-worthy relationship with the client in order to let him to share me more with his own’s emotion and my caring may let him to identify his own goal and the willing of changes. Expressive art therapy may like to cope with his difficulties of expressing his own feeling when I am asking some open question. Furthermore, the gestalt therapy would like to help client to aware with his gesture like refuse having eye contact with other so as to relate his gesture to his feeling and let him to pay attention to.
