Potential Solution Problems And The Diagram-Myassignmenthelp.Com

Question: Discuss About The Potential Solution Problems And The Diagram? Answer: Introduction: As the luxury was reserved for the tech-savvy and rich people, the IoT or Internet of Things has been invading the private dwellings of the common people with high pace. The revolution has been connecting various commonly used home appliances with the Internet (Sivaraman et al., 2015). The potential of IoT at homes have been evaluated in the report. It includes the IoT systems like the smart phones or the smart TVs. The report has identified and discussed the present devices used in the home. It has evaluated the challenges like privacy, security, connectivity, control and usage. Lastly it has provided the potential solution of the problems and the diagram of the layout of the dwelling. Identifying and discussing the current devices that are to be used at home: The helmet concussion sensor: Everyone needs to secure the concussions. As the recent research has been showing particularly, the greater connection is present between the neurological and concussion issues further in life. It has been especially significant in the sports like hockey and football where the products such as Shockbox have been coming in handy (Amadeo et al., 2015). It contains the software attaching the protective helmets and has been using the accelerometers for measuring the impact of the head effect. The data is sent to the smart-phone of the coach or parent through Bluetooth allowing them to take critical decisions. Medical Alert Watch: This has been the Smartwatch has been allowing the remote healthcare monitoring the loved ones. This Smartwatch has been tracking as well as other types of the regular activities. Moreover, it has been providing the emergency assist button alerting the Lively for calling in and checking that all the things have been alright (Yoon, Park Yoo, 2015). Its features have been outstanding and it has been offering that could be placed in the home such that the system could learn the normal habits. This includes the opening of the refrigerator or taking medication. Dog Activity Monitor: Since the market for the health devices has been new, this smart device has been monitoring the health of the dog. This device from the Fitbark has been the Fitbit for the dogs. This has been useful in measuring the activity or the dogs and the sleeping quality. Moreover, it has been delivering the theoretically useful data regarding the behaviors. Smart Running Shoes: These shoes have been capable of doing all the standard tracking like the split times, distance ran and time. The using of the acquisition of the MapMyFitness, the company Under Armour has been making that such that those shoes integrate the MapMyRun. This has been for delivering the GPS data for the runs. Smart Fitness Clothing: Every garment has comprised of the built-in-sensors that have been measuring the muscle activities. This is done by electromyography. The data has been relayed to the hub of Iron Man that could be attached to the chest or leg. The hub has been sending the data back to the smartphone allowing the user to assess the performance during various exercises and appropriate the techniques. Garden Sensor: The organization named Parrot has been creating wireless devices since 1994. This has been popular for their present range of drones. Despite that, they have been also making that an outstanding sensor. The sensor has been analyzing the air temperature, soil moisture, fertilizer level and the sunlight. Next, by utilizing the Bluetooth connection to the iOS or Android device, it could alert then regarding all the necessities of the plant. Smart Garage Controller: The smart door controller of Garageio is useful in opening and closing the garage doors using the smartphone application. This has been also promising to warn the user as they leave the garage door open by mistake. The actual interesting feature has been that the user could grant the access of the garage door to various people (Jie et al., 2013). Raspberry Pi Amazon Echo: It has been already the most flexible and low-expensive device of computing. It could also create the outstanding DIY device of IoT. RainMachine Mini-8, Touch HD-12, or Touch HD-16: The RainMachine has been saving the water and keeping the plants healthy through using the forecasts of federal weather in automatically adjusting the watering as required. The user could also program that to shut that off in particular months, not to water at the freeze conditions and complying with the restrictions of the locality. Abode Connected Home Security: Provided the monthly charges for few products, the overly restricted capabilities of the still others and the dubious security of the others, the IoT system of home security could be preferred. The Abode has comprised of various components (Santoso Vun, 2015). At the core, it contains the hub. This contains the intelligence, radio controller, Internet connection, battery backup and the siren. Evaluating the issues and providing potential solutions for these issues: Same as the conventional systems, the smart homes have been experiencing various ups and downs plaguing the latest technologies. Almost regularly, new technology sites have been putting up articles relating how the smart systems could be hacked. Moreover, there have been proofs that those adopting the smart devices such as security and thermostats systems have abandoned them. The issues are highlighted below. Usage: The usage has been a crucial problem in understanding how billions of the new smart home devices have been flooding online. The unmaintained devices have been spewing all kinds of staffs onto the online. Most of them have possessed the operating system maintained by anyone. Most of the vendors of IoT have been going out of business. Their devices have been comprised of bugs that are impossible to fix (Yoshigoe et al., 2015). The rising concern is that what that has been to do with the ability of the Internet in dealing with the malicious actors. The way in which the issues of optimization and [performance around the Internet could be recognized and solved is also a concern the fast-changing and robust scenario. A number of devices that are connected online only rises quicker as the more and, more elements turn Internet-enabled. For example, it must be assured about the basic issues in front of the numerous refrigerators asking to buy milk towards the way home. Control: There has been a rising concern whether the devices could deliver the services required to contact them at first. For instance, various thermostats based on Internet and applications on the phone controlled by the systems have not been communicating directly or peer-to-peer. Rather than this, everyone has been communicating independently with the rendezvous there and the cloud. The commercial impacts of the systems have been deep and wide (Chung et al., 2014). Virtually all the machines operating in all the sectors and market could be connected to the Internet. The problem of control with it is that how these devices are tracked, assuring the billions of smart things has been up. Connectivity: All the devices using the electricity have been collecting the data and are connected to the Internet. However, there could be various wrong outcomes originating from this. The privacy and security issues around the IoT have been so intensive that those are almost overwhelming. The smart home has been connecting many kinds of digital devices for communicating with others via the Internet. These devices have been forming the home area network. Here the communications have been enabled through various protocols. Every device has been designed by various organizations with various technologies and standards. Thus there exist various issues in the connectivity. The security issues are described below: Vulnerability to Hacking: The experts are able to hack into the real and on the market devices taking sufficient time and energy. This indicates that the hackers could also likely capable of replicating their efforts (Perumal et al., 2016). The readiness of the companies: From the various surveys made, only just a few percent of the enterprises have been feeling confident regarding the security of their devices against the hackers. True security: The securing of the IoT devices have been just more than just simplifying the securing of the real data themselves (Shim, 2015). The organizations have also been needed to create the security in the network connections and the software applications linking to the devices. Privacy: Too Much Data: The total quantity of data generated by the IoT devices has been staggering. This has been creating more access points for the hackers and leaving the sensitive information vulnerable. Unwanted Public Profile: The organizations are able to utilize the gathered information that the clients have been willingly offering to create the employment decisions (Nobakht, Sivaraman Boreli, 2016). For instance, the insurance company could collect data regarding the users health or the life insurance because of the fitness trackers. Eavesdropping: The hackers or manufacturers are able to utilize the devices in virtually invading the peoples home. The researchers from Germany have accomplished that through intercepting the unencrypted data from the smart meter device for determining what show in the television was been watched at any moment. Consumer confidence: All of the issues have been putting the dent into the desire of the consumers for purchasing the connected products that prevent the IoT from the fulfilling of their actual potential. Providing potential solutions for the issues: There have been two approaches to get around the issues. The first one has been to opt for the service of device aggregator such as ATT -0.63% along with the service of Digital Life. Here they have been providing as a single app along with a box of the consolidated wireless adapter. The consumer could create a multi-year agreement of service same as the phone. This must reduce the initial outlay of cash (Gubbi et al., 2013). Same as the ATT in the cable devices, the consumers would receive the best in breed services, hardware, and software. The solutions are discussed below. The Revolvs approach: This approach has been enabling the customers in buying the end point products that are best in breed. However, this has been integrating the software and hardware. This has been indicating the creation of single applications from the disparate apps and also consolidating every wireless adapter. Revolv, a popular company has been intent to perform the same thing. They have been pulling every disparate wireless box under a single box and then pulling those disparate applications under one single application (Skouby Lynggaard, 2014). Apart from these there are various security measures that could be adapted for safeguarding the IoT devices and solutions. The security could be emended at various layers like threat management, application and data, network and endpoint. Protection could be included in the media layer and the physical layer of the network. The extent of the necessary security could be determined in the edge devices and its effect over time. The network could be protected in overcoming the problems to protect the applications (Perumal, Datta Bonnet, 2015). Moreover a security posture and a cloud strategy could be incorporated. The security integrity must be maintained around the complete life-cycle of the product. Lastly the proper security is needed to applied to every potential risks and then the threat is to be evaluated. Diagram of the dwelling layout: Figure 1: The diagram denoting the layout of the dwelling along with the home appliances (Source: Created by Author) Conclusion: The IoT has been leading the path towards the smart world. This is done with the ubiquitous networking and computing to simplify various tasks around the users. They have also been providing various tasks like easy controlling of various phenomenons all around. Under the IoT, the items and environmental from the daily routine are developed with the communication and computing technologies. They have been joining the framework of communication and meeting various services using the wired or wireless communications. These interconnected machines have been performing the new services needed to be carried out through the present or future Internet. However the smart home systems have not been devoid of various threats. The report has identified the various measures to do away with the risks. It involves the going for the service of device aggregator and the Revolvs approach. Thus a new wave of the productivity growth could be expected with the improvement in the quality of human life.

Galileo And Newton Essay Research Paper Galileo free essay sample

Galileo And Newton Essay, Research Paper Galileo and Newton 2/4/97 Galileo believed the physical universe to be bounded. He says that all material things have # 8220 ; this or that form # 8221 ; and are little or big in relation to other things. He besides says that stuff objects are either in gesture or at remainder, touching or non touching some other organic structure, and are either one in figure, or many. The cardinal belongingss of the material universe are mathematical and strengthened through experimentation. Galileo excludes the belongingss of gustatory sensations, olfactory properties, colourss, and so on when depicting the material universe. He states that these belongingss # 8220 ; shack merely in the consciousness. # 8221 ; These latter belongingss would discontinue to be without the life animal so the mathematically defined belongingss are the most accurate in depicting the material universe. Galileo seems to prove his beliefs through experimentation and mathematical logical thinking. He sites illustrations in life that support his hypothesis. His statement is of a scientific nature because he is doing a hypothesis on a typical type of construct. The decisions that Galileo made relate straight to the work in natural philosophies for which he is so good known. His decisions put accent on forms, Numberss, and gesture which are all belongingss that lend themselves to back up through # 8220 ; concluding back and Forth between theory and experiment. # 8221 ; I feel that Galileo # 8217 ; s statement is a valid one because it explains dealingss in nature and the physical universe through mathematical analysis. This allows him to specify a universe outside of human being that can be logically calculated and explained. His position describes the universe in which life animals live and non contrasts it to the universe within life animals. The job with Galileo # 8217 ; s position is that it pioneers a scientific mentality but neer really fulfills it. Newton believes the universe is finally made up of difficult atoms that can retain different belongingss. The cardinal belongingss are solid, massy, impenetrable, and movable atoms. He believes God created affair in the get downing in such a manner to let the atoms to take on mathematical signifiers. His attack is a scientific 1 because he patterns the continual interaction of experiment and theory. It is the difficult atoms that move in such a manner that can be assigned certain mathematical rules that clearly explain the interaction of organic structures. Newton # 8217 ; s decision seems to be a strong one because it trades with the universe being made up of atoms and shows how these atoms act with each other in a manner that can be explained scientifically. I like the thought of organized flow in the universe and God being the Godhead of it all. The mathematical/scientific attack offers account to how the atoms are traveling. Galileo and Newton differ in certain facets of their apprehension of the physical universe. Galileo doesn # 8217 ; t set much accent on the function of creativeness in scientific discipline. Newton believes in the mathematical and experimentation mentality of scientific discipline pioneered by Galileo but he believed that new constructs are the merchandise of originative imaginativeness. He felt that math should explicate the constructs imagined. Newton extended thoughts pioneered by Galileo on issues of forces, multitudes, forms, and signifiers. Newton didn # 8217 ; t experience that the scientific theory needed to reply every inquiry asked about a phenomenon in order to be utile. Galileo and Newton make a strong statement for the deficiency of intents or values in nature. Their scientific heads sought replies on a logical graduated table. They could analyse the stuff universe through computations and in this math was suited account. In the survey of natural philosophies, intents are irrelevant. Physicss looks for the mathematical account of constructs and doesn # 8217 ; t need to analyze the intent behind such. It is concerned merely with what happens and how it is go oning. The doctrine of natural philosophies could widen the constructs to incorporate intent. The universe is the merchandise of the opportunity multitude of atoms. Everything is comprised of atoms and it makes up the known universe to which mathematical rules analyze. If there are no intents in the existence and this fact is supported through scientific survey, so there is purpose in that scientific discipline works to interrupt down the material universe to series of facts that are invariably accommodating to one another. The universe position introduced by 17th century mechanists is scientific discipline. Science became the reply or manner to the reply. Aristotelean position is concerned with the concluding province whereas as the scientists thought the of import information was the full procedure, or efficient causes. It is besides concerned with the intents and values that are at work in nature while mechanists see nature as a mechanism that operates blindly, and the forces of nature are in themselves wholly apathetic to intents or values. Newton, in resistance to Aristotle, didn # 8217 ; t believe in unknown causes. He wanted replies that were or could be proven. I feel that Newton has the stronger position because his trades with discernible facts and non merely constructs. Newton # 8217 ; s thoughts about the universe extend the constructs of Democritus. Newton strengthens the mechanistic position by supplying it with mathematical logical thinking. Aristotle # 8217 ; s statement of Democritus weakens when covering with Newton. He had scientific grounds that backed up his claims. However, Newton still doesn # 8217 ; t concern mechanism with the reply of # 8220 ; why # 8221 ; but instead looked to understand the immediate # 8220 ; how. # 8221 ; Newton would hold that Democritus didn # 8217 ; t back up his statements with fact and that they are largely conceptual positions. Newton would hold to back up Democritus for originating the atomic theory and would likely state that his thoughts are relevant and non over simplified. Form in the universe is the consequence of other causes in a long, scientific concatenation of efficient causes by the interactions of atoms. In a manner Newton # 8217 ; s cosmogonic thoughts are better because he was able to support interactions within the existence with mathematical logical thinking. He finally came to the belief that # 8220 ; there is no scientific account for the form of the planets, # 8221 ; keeping that coplanar orbits with speeds in the same way can non be accounted for by natural causes. This lead him to the reply that God prevents the existence from fall ining. I feel this is better than Timaeus # 8217 ; s position of forms in the universe because he has to fling certain information because he himself can # 8217 ; t happen mathematical cogent evidence for these theories. Subsequently, Laplace will be able to account for the coplanar character of the solar system by demoing insufficiencies in Newton # 8217 ; s scientific discipline. This is a recognition to Newton in that if he couldn # 8217 ; t back a theory with mathematical ground and experiment, he wasn # 8217 ; t merely traveling to presume it to be true. Galileo and Newton along with Plato believed in atoms or atoms as the stuff of which all things are made of. I besides infer that they would slightly hold on how truth can be perceived otherwise in the same mode that sentiment is different from cognition ( this thought was illustrated by Plato in his divided line analogy ) . For the mechanists, sentiment is a perceptual experience of truth but an wrong one because it is non supported with mathematical logical thinking and experimentation, which would so do it cognition.

Investigation into the Factors that affect the Viscosity of Magma Essay Example

Investigation into the Factors that affect the Viscosity of Magma Essay Magma is molten material beneath or within the earths crust, from which igneous rock is formed. Magma can only be in places that are hot enough to melt rocks. When magma is formed it rises to the surface through the earths crust. When magma reaches the earths surface it is known as lava. It can erupt on the earths surface, either on land or under the ocean, by a volcano or through a fissure. It solidifies into igneous rock that is also called lava. Before reaching the earths surface, the mixture of solid and liquid rock, and gases, is known as magma. Lava is composed chiefly of silica and the oxides of aluminium, iron, magnesium, calcium, sodium, and potassium.There are two types of magma granitic magma and basaltic magma. Both of these types of magma contain SiO2 (sulphur dioxide). Granitic magma is very thick and contains 70% Sulphur Dioxide it has a temperature of about 750((. Basaltic magma is runny and contains 45% Sulphur Dioxide it has a temperature of 1100((. The more SiO2 bo nds the stronger the magma is, also meaning it is thicker.My Experiment is on the viscosity of magma and how you would measure it. Factors that could affect the viscosity of magma are Temperature and composition. Composition because magma contains a certain amount of water and temperature because this will tell me how runny the magma is at different temperatures.The technical definition of Viscosity is; the property of resting alternation in position of its parts relative to each other, which simply means how runny a substance is. This is what I will be trying to find out and the substance is magma.Pre-TestsIn my experiment I unfortunately wont be able to use real magma as it is at such high temperatures, it would expensive and inconvenient to get hold of and is also toxic. So instead of Magma I will be using a substance called glycerol. I have looked into different substances and their advantages and disadvantages. I knew it had to be something that was still liquid in a freezer it also had to be a substance that can be diluted easily. I have looked into using syrup and decided it was a bad idea because it gets very messy and sticky when hot and is also tempting to eat. I also looked into using thick engine oil but this wasnt very good either as you can only dilute it in white spirit, which could become dangerous and expensive. I have decided on Glycerol because it is cheap dissolves in water, it isnt poisonous and has similar properties to magma.With the substance and the factors that could affect the viscosity of glycerol I had to find the easiest way to test them. Temperature I can vary by heating the glycerol and composition I can mix the glycerol with water I then had to find out what the affect of these factors was on the glycerol. I looked into a couple of ways to test the affect of temperature and composition. The first one I came up with was to dribble the glycerol along a set-up of gutters and time to see how long it takes to travel down the gutters and fill up a certain amount of the pot at the bottom. This is a diagram of how that experiment was set up:Through research I have discovered lots of problems with this method like by the time the glycerol has travelled along the gutter it will have cooled down, it is messy, it is hard to pour at a constant speed. The other method I came up with was to fill a measuring cylinder with glycerol then drop a marble in the top and time to see how long it takes to reach the bottom. There are also problems involved in this method like it is also messy, you have to make sure you use all of the same equipment, it is tricky to get the marble out, once it is at the bottom of the tube.MethodI have looked at my results from my pre tests and this method seems to be safe, easy and not too time consuming.Below is diagram of how I set up my equipment used to do my experiment. When I choose temperature as the variable I kept the volume of glycerol the same. I had to be very careful to make sure I use d the exact same measuring cylinder, marble and stop watch. These are all things that needed to be taken into account if I want to make my experiment fair. The volume of glycerol used was 25cm(. To make sure I used the same equipment each time I labelled my measuring cylinder put the marble in it and pushed tissue in the top of it.I had to heat the glycerol to get it to the desired temperatures I did this using a water bath. My starting temperature was 20(C and rising by 10 each time. My maximum temperature was 70(C. Once the glycerol was at the desired temperature, I put 25cm( of it into my measuring cylinder and dropped my marble in the top of it timing it to see how long it took to reach the bottom. I repeated the experiment three times to make it a fair test.The second experiment was on composition this was a lot harder to carry out. I used the exact same equipment that I used for temperature. In this experiment composition is the variable and I kept the temperature constant at room temp. I used 25cm( of diluted glycerol. I diluted the glycerol by using the ratio 24glycerol: 1water, 23glycerol: 2water.I used the same method for this experiment as I did for temperature, for each of the ratios I repeated the experiment three times for each mix of glycerol and water. This helped to make sure that my results were reliable and fair.PredictionIn my experiment I had to use glycerol instead of magma but there are things that can be related to each one like that the more viscous a substance is the thicker it is. There are two factors that affect the viscosity of glycerol, which means there are probably two factors that affect the viscosity of magma. The higher the temperature of the glycerol the less viscous it is. Granitic magma is hotter than basaltic so it is likely that it basaltic will be thicker. The same kind of theory can be used for composition the greater the amount of water present the less viscous it is. There is a lot of water present in magma and so t he same will happen the more water the less viscous.SafetyAlthough I have decided to use glycerol instead of magma there are still lab safety precautions that have to be followed.* Lab coats musty be worn at all times* Ties should be taken off* Long hair should be tied back* Safety goggles must worn at all times* We will be dealing with some high temperatures so caution must be taken when heating or carrying the glycerol* Bags should be kept out of the way* You shouldnt sit down at any time throughout the experimentTable to show results for temperatureTemp((C)Time (seconds)123average20113112112112304947477484032303231502523252360131113127013111112Table to show results of compositionRatio of glycerol two waterTime (seconds)123Average24:13132333223:22931303022:32829272820:51110111115:10333310:1511110:250.90.70.80.8AnalysisMy graphs seem to back up my theory that as the temperature was increased the time it took for the marble to travel to the bottom of the tube reduced. In the second graph, which shows the results from the composition experiment, from this I can see that my prediction that as the amount of water added to the glycerol increased the time taken for the marble to travel to the bottom of the tube reduced. This proves that two factors that effect magma are temperature and composition.There were two experiments carried out so I will analyse each of them individually in the following paragraphs.The first experiment I carried out was on the effects of temperature on the viscosity of magma. It is obvious that the temperature has an affect on the viscosity of the glycerol. The reason for the loss in thickness is because as the temperature increases the kinetic energy of the molecules in the glycerol increased so their bonds weakened and broke there for the glycerol became less viscous. This would also happen in magma, as there are strong Si-O bonds, which as the temperature increased so would their kinetic energy and so weakening their bonds these are the bonds, which made the magma so thick.The second experiment I carried out was to test the effect of composition on the viscosity of magma. My results show that as the concentration of water in the glycerol increased the time taken for the marble to pass through the glycerol to the bottom of the tube increased as well. The glycerol became runnier because the more water bonds there are present the weaker the bonds between glycerol molecules become. This is also what would happen in magma as the water bonds would weaken the Si-O bonds in the magma and so making it runnier.By looking at my results and background work I have realised that, Basaltic magma is hotter so will be runnier than granitic magma because the kinetic energy in basaltic magma is higher so it has weaker bonds. With the composition basaltic magma has alt more water in it than granitic and so the Si-O bonds are weaker. From this I can predict that basaltic magma is more viscous and is runnier.EvaluationThe results I rece ived backed up my prediction and I feel were very reliable. Although these results were good it would have been nearly impossible to get perfect results with the equipment we used. There are also two other main sources of error these are human error. When measuring out the ratios in the composition experiment I could of made some mistakes and not quite got the concentration correct. Another chance for human error would have been starting and stopping the stopwatch when the marble was dropped into the measuring cylinder and hit the bottom. It would have been impossible to get this exactly right unless we could use really high tech equipment, which could have been very expensive. The other type of possible error was to do with equipment.There was a lack of glycerol so for the composition experiment I had to use the glycerol from the temperature experiment this could have been a source of error. When heating the glycerol we had do it in a water bath which wasnt very accurate as once it was at the right temperature I had to carry it back over to my desk were I was working, by this time it was already starting to cool down. The last source of error I could easily recognise was that the marble and the measuring cylinder was a very tight fit and I think the marble sometimes got stuck on the edge of the tube. Other than these possible causes of error I feel the experiment went ahead very smoothly without any injuries or major problems.

Kosovo Conflict Essays - AlbaniaSerbia Relations, Kosovo War

Kosovo Conflict Essays - AlbaniaSerbia Relations, Kosovo War Kosovo Conflict Kosovo Background of Kosovo: -The Balkans have been a very unstable region for hundreds of years. The reason for contention is because of ethnic origin and disputes of which race owns which land.. That is the reason for the dispute over Kosovo is because of the same thing. This is a very complicated situation, that I don't really know everything about. I just kind of know the basics. Back in the 1500 hundreds, the Serbs conquered the Kosovo area, slowly and gradually over the years the Ethnic Albanians started occupying the territory, until before the bombing began, Kosovo consisted of 90% Ethnic Albanians. Well, the Serbs didn't like this, especially Milosevic who is the ruler over Serbia. Since Kosovo has many historical ties to the Serbs, and the Serbs conquered that territory back in the 1500 hundreds, Milosevic wanted to reclaim their rightful territory. And his method to do this was through ethnic cleansing Kosovo. Stats: -Milosevic has been doing this subtlety for years, and as of last fall has increased his killing of ethnic Albainians. To date, there are now 200,00 people dead as a result of Milosevic's ethnic cleansing. That is probably a very low figure. 100,000 Kosovar men are now missing, which might be the reason for the mass graves that have been pictured. Nearly one half a million people have been expelled from their homes, many forced out at gunpoint, while the Serbian troops destroyed their identity papers, making them unable to return to their homes. This flood of refugees have overwhelmed neighboring countries, who are economically weak, and are unable to take in all the refugees. 600,000 Kosovars are surviving off the land in mountains nearby. Controversy: -You might wonder what business the U.S. has in a country on the other side of the world, where it seems to be no political interest whatsoever. That is a big controversery of whether or not NATO should be involved. At first I was against NATO involvement for just those reasons, why should NATO get involved where there would be no benefit to us, because this was more of a humanitarian issue. But as I researched this and read more about it, I am in favor of NATO involvement. I believe that we should do everything possible to help stop Tyrants from killing innocent people. Which is what was and is occuring in Kosovo. -But I am against NATO in who, why and how NATO is handling this conflict. Who: -NATO is very hypocritical by saying they got involved in this situation purely because of humanitarian reasons. There have been many occasions where the U.S. looked the other way on bigger humanitarian disasters. In West Africa, there was a similar ethnic cleansing situation where the U.S. did not get involved. Why: -In the begging, where NATO was on the verge of bombing Kosovo, Clinton spoke in a public meeting about why we were getting involved. He said, trying to get public approval, that the reason the U.S. is getting involved is largely an economical reason. He said that this war would help the U.S. financially. By getting involved, we would become partners with Europe, thus increasing a trade relationship. That is what I am against. I am against the U.S./Clinton thinking more about how much money we can get, rather than saving innocent lives from being brutally murdered. -After the bombing had dragged on for longer than expected, which was only about a week in some people's opinion, the objectives were stated as follows: To stop ethnic cleansing, stop flood of refugees into nieghboring countries, stop NATO from splitting, prevent Milosevic from strengthening his grip on the Balkan region. And, after over 2 months of involvement, NATO has not been able to meet those objectives. -Bob Bennet said that the current bombing has been no help to the Albanians and Macedonians, who have seen hundreds of thousands of refugees flood across the borders into their ill-equipped countries. It has been of no help to NATO, an alliance that has seen its military stocks drawn down to dangerously low levels, with no effects on the atrocities going on in the killing fields. -One speculated reason to get involved was because of the military stategic point in the

3000 words - Essay Example Experiences of stress may change the way a person thinks about everything, they way they behave and their pattern of physiological activities. The changes under certain circumstances can lead to the increase of risks associated with psychological, social and physical ill-health and at times behaviours that are inappropriate (Houdmont and Leka, 2010, p37). Stress can be defined as the non-specific response by the body as a result of any demand made on it. Demand in this case is defined as a stressor which may arise from a stimulus or an event. Stressors come in many different ways and they range from time pressure, extreme pressure, and extreme temperature to physical assault. When an individual is exposed to such a stressor, a physiological stress response occurs. The response can be measured through observation by different measures such as dilated pupils, increased heart rate and increased blood pressure according to Hosek, Kavanagh and Miller (2006, p23). Physiological manifestations of stress are identical regardless of the type of external demand but its effect on performance varies among individuals. The effect on performance ranges from physical impairments and cognitive reactions. Stress-performance relationship models indicate quite different scenarios. There is U-shaped and negative linear stress-relationship models. In the U-shaped model, performance improves when the stimulus reaches a moderate level and decreases when the stimulus levels increase beyond the moderate levels. Although this is the case, individual differences that exist may alter the shape of the curve. According to a research done, evidence showed that an inverted-U relationship exists in the industrial sector especially on job performance. In a negative linear relationship, stress regardless of the level reduces work performance through draining the person’s energy, time and concentration.

Final Exam - Essay Example For instance, the government of UAE has a tendency of overstaffing departments. In most of these cases, these individuals do not have the necessary educational backgrounds and experiences to fit, in these departments. The need to overstaff government departments and agencies arise from the unemployment rates (Jabbra & Jabbra 137). Additionally, this need arises from the country’s dependence on oil production and economy. Recent efforts focusing on branching out face stiff competition and resistance from the oil industry and government activities directed towards the oil industry. Few non-energy based businesses face challenges in thriving in this economy because they lack the work force that has been concentrated, in the energy industry. The complexity and rigidity of rules in UAE further provide challenges to the adoption of Western governmental cultures. These rules are developed with an aim of concentrating power and growing the size of the government. This has led to an in crease in unethical practices such as nepotism, corruption and misuse of public resources and office. The government or public sector creates immense job opportunities for the UAE residents. However, these jobs are usually open for UAE residents. For instance, Etisalat, which is a semi governmental corporation, is overstaffed with UAE residents (Jabbra & Jabbra 140). ... For instance, in 2010, the government was rocked with several corruption scandals that threatened its administrative processes. The size and extent of power, in UAE government, facilitate instances of corruption. In addition, corruption is a crucial issue in government owned corporations especially in the oil and telecommunication industries. Though corruption is not as rampant as in other states, it occurs through careless and unscrupulous businesses. It is essential to note that administrative processes in UAE occur in an environment that does not facilitate accountability (Jabbra & Jabbra 141). The administrative environment in UAE does not have proper checks, balances, and appropriate safeguards that can prevent these instances of corruption. As public servants carry out their official duties, they lack accountability for their behaviors and actions, which favors instances of corruption. Establishing accountability in administrative processes is a crucial tool and strategy in red ucing the unenthusiastic effects of corruption. In this case, all public servants will be accountable for their actions and decisions. This ensures that these public servants reach decisions that aim at improving their departments. Accountability is essential because workers become answerable for their decisions and actions (Jabbra & Jabbra 138). Additionally, it creates awareness that negative actions, behaviors and decisions lead to possible legal proceedings. Accountability will also help in addressing bureaucracy because it helps in the development of a functional administrative structure with spelt out duties and responsibilities for each administrative function. Question 3 In my opinion, public administration is both an art and science. Public
