Government Control and the Green Scare Essays - Terrorism

Government Control and the Green Scare In the twenty first century, our greatest war is the War on Terror. For Americans, ever since 9/11 we fear more than ever for our security at home more than abroad. Our security is tighter than ever, sometimes to the point of being ridiculous, and we have been taught to accept government agencies stepping on our rights because it "keeps us safe." We have entered into an age of racial profiling, distrust, and fear that has allowed our government to use bills like the P.A.T.R.I.O.T Act to work around our individual rights. In times of fear, we are more pliable to the influences of those who claim they can protect us. This era of fear leads us into a big issue that is often not discussed or is hushed up: the unlawful arrest of activists in the name of homeland security. And the environmental activists have seen the worst of it. Environmental activists are an easy target for a suspicious government and a willingly submissive public. They are easy to target because they, in general, are outspoken and sometimes violent. Because they try to be so in the public eye, they become easy targets to track down unlike more allusive enemies. Michael Brady Although this violence is very rarely targeted at people, this still gives the government ammunition to detain violent and nonviolent protestors alike. And because the government and the media have become so adapt at making environmental activists look like radical terrorists, the general public lets cases like the SHAC 7 happen unjustly. Even when it is fair for activists to be brought up on charges, they are more often than not given inflated sentences, sometimes being sentenced longer than violent religious terrorists who were out to do harm (Potter). If you go to the website for Terrorism Research and Analysis Consortium' or TRAC', you will find that even within organizations there is some confusion as to the threat of environmental terrorism in our country. The blurb under Environmental Terrorist Groups' reads, "Most Significant Terror Threat to the United States since 1976, environmental terrorists within the United States have carried out over one thousand criminal acts and caused over one hundred and ten million dollars worth of damage. But the image of environmental activists as dangerous, even violent criminals is still jarring to the average American. We do not tend to think of environmental activism as being in the same category as other types of "terrorists" - including militias, jihadists or nationalist activists throughout the world. However, the Federal Bureau of Investigation defines environmental terrorism (or ecoterrorism) as Michael Brady the most significant domestic terror threat facing the United States today. And this threat is seen to have increased significantly in the past twenty years in terms of the types of acts committed, their potential for deadly violence and the numbers of individuals involved in committing these acts." The most significant domestic terror threat facing the US. Yes, you read that correctly. Not white supremacy, not radical extremism, but environmental activism is our nations greatest threat. They even admit the fact that it is very hard for most Americans to image environmental activists as terrorists and yet they are. There has yet to be a single human killed in an action put forward by an environmental rights group, yet they are labeled our most dangerous threat. Here is where the issue starts. With the FBI. Before I discuss the FBI's current issues of attack, lets remind ourselves of the government's past intrusions on our civil liberties, the most famous and most recent case being the Red Scare of the Cold War. Following the end of World War II, the US and the USSR moved into a state of nonviolent war. A power play really. As the world's two great super powers, they both wanted to one up each other constantly. And they were constantly fearing that the others political theory would take over the others. Because of this, the US feel into this constant fear of the Red Scare', a fear that communism would take over. This fear gave government officials like Joseph McCarthy the right to recreate the age-old witch-hunt. For the

Yoga essays

Yoga essays Yoga is a unique ancient healing art originating from India more than six thousand years ago. This ancient art of movement is a low intensity non-competitive form of exercise that can be safely practiced by children at any level of physical fitness. Yoga is derived from Sanskrit, one of the worlds most ancient languages. In its simplest form, yoga means a bringing together of the parts in order to create a union or balance of a persons body, mind and spirit. (Dworkis, www.extensionyoga.com) It was developed by yogis who went into the jungles of India, thousands of years ago to meditate. During meditation these yogis observed animal movements. The development of some of the present day yoga postures actually come from these observations. (Holander, 97, 1) This form of fitness session is a great alternative to do with a group of primary aged students. Firstly the non-competitive and overall harmonious nature of yoga can alleviate any feelings of physical inadequacies that some students may harbour. Therefore, you are more likely to see greater motivation and participation towards the activities as the students who may not be as physically fit or coordinated as other classmates will have the opportunity to try out a new exercise without ridicule or defeat. Secondly this form of fitness session is a fantastic one to do with students who are within their peak height velocity or students experiencing the effects of puberty. This scientific system of exercises or poses are designed to strengthen bones, stretch muscles, massage internal organs, increase blood flow and increase flexibility of the tendons, joints and ligaments. (Holander, 97, 1) This is particularly important when concerning primary aged students around or during their pubert al growth spurt. Considering girls peak height velocity is around 10-12 and 12-14 in boys. Physical activity that does not contain the same characteristics as yoga can aid the cau...

Speech using the Rogerian style of argumentation Essay

Speech using the Rogerian style of argumentation - Essay Example Several instances have been reported concerning the increased aggression among the victims. Others also report increased criminal or violent behavior among the victims. In other situations, corporal punishment in schools can lead to escalated antisocial behavior and moral internalization among the learners. My position differs from those who argue that corporal punishment should not be banned in schools or other learning institutions. My position is that corporal punishment in schools and other learning institutions should be banned. This does not include normal discipline mechanisms that parent use at home. It also does not include the nonviolent punitive methods employed by teachers to enhance discipline among learners. Corporal punishment in public and private schools and other learning institutions should be banned because it poses devastating effects on the learners. These include loss of good family relationship and damage to education. It leads to all forms of violation of the fundamental rights of children such as the right to education and good

Is There Such a Thing as International Law in the World Today Term Paper

Is There Such a Thing as International Law in the World Today - Term Paper Example Additionally, treaties like the Geneva Conventions may at times require the conformity of national law (De Boer 2001). The implication of this is that there is a world order that all countries abide to but with no clearly drafted international laws that ought to be followed by all nation states. Additionally, certain issues like homosexuality, differences in political ideologies and gender discrimination prevent international laws from achieving legitimacy. International law therefore is a set of laws formed by international treaties, customs, and other organizations that govern the relations between or among different sovereign nations. Here, the international customs refer to the customs that have evolved over centuries. Treaties and international agreements on the other hand are agreements among different nation states. The international organizations and conferences are mainly composed of different sovereign nation states and are normally bound by a treaty, for instance the 1980 Convention on Contracts for the International Sales of Goods (CISG). The Nature of International Law International law is very different from the other areas of law because it does not have a defined governing body or area but instead refers to different set of rules, laws and customs that impact, govern and deal with the legal interactions between different nation states, governments, organizations and businesses. It comprehensively deals with the rights and responsibilities of the involved parties clearly defining and elucidating the procedures to be followed in case of any misunderstandings. International law cuts across many countries and regions which makes it agreeable to all the member states. For this to be possible, it borrows charters (i.e. the United Nations Charter), agreements, accords, and treaties, legal precedents of the International Court of Justice (The World Court), memorandums and tribunals. What makes international law a voluntary endeavor is that it does not h ave a unique enforcing entity and governing body. This means that for any enforcement to exist, all the signatory parties have to consent and adhere to that specific decision and assist the court in the implementation process. A good example of this is the East African Community where the member states have laws that govern them as a unit. The laws that address matters of international concern include both the statutes created by governing bodies (civil law) and the common law (case law) because of the diverse nature of the different legal systems and historical backgrounds of the different countries involved. Under the international law, all the facets of national law are covered and go on to include aspects like substantive law, remedies and procedure. In order to make the laws operable in the signatory countries, there are certain principles or guidelines that are normally followed when it comes to their formulation and implementation (Alam 399). However it should be noted that t hey only work on the basis that there is courtesy and respect between the member states. The principles of International Law The Principle of Comity The principle of comity provides a code of decorum that governs court interactions among the different localities, foreign countries and member states. Under this

Strategy Assignment Example | Topics and Well Written Essays - 1000 words

Strategy - Assignment Example 2) According to Wal-Mart, it needs substantial brands to form associations with it in order to attract affluent customers and also have a tendency of increasing peripheral business by selling other commodities. Therefore, forming associations with Levis’ allows it to attach a designer brand name with it that is accepted and received well in affluent customer’s segment. 3) Considering this case study, Wal-Mart has an edge over Levis’ in this corporate strategic alliance. This is so because Levis’ needs Wal-Mart for its business expansion as its own showrooms and other smaller retail networks have been proven incapable of attracting major customer base. Secondly, Levis’ has made considerable capital investment along with extensive business restructuring to suit Wal-Mart’s model. Therefore, Levis’ is dependent on Wal-Mart for cost-recovery and further business revival. Whereas Wal-Mart has a tendency of switching to other suppliers who wi ll offer better profit margins without incurring much liability. Therefore, Wal-Mart has a greater bargaining power as compared to Levis’. 4) Wal-Mart follows a broad target/ cost leadership generic strategy (Porter, 1980). It has multiple product lines that cater to every demographic segment. Furthermore, it has an extensive retail model with around 9000 stores worldwide. Such extensive network makes it a premium choice of suppliers due to which it has a greater bargaining power to persuade suppliers for providing their products at considerably low prices, as compared to other retail stores. 5) ‘Barriers to entry’ is an edge used by various leading market players to create obstacles for preventing new competitors from easily entering into market, industry or particular area (Sullivan & Sheffrin, 2003). Wal-Mart has developed a state of art automated system that is synched with its suppliers through point-of –sale mechanism. Therefore, the moment a product is bought, a supplier is notified which results into timely product delivery. As a result, customers prefer to stay with Wal-Mart since they know that their desired product will be available readily. This strong link with suppliers requires higher switching cost which is difficult to incur for its competition. As a result, their customers would also prefer Wal-Mart over them (Competing with information technology, n.d). 6) Value chain constitutes of following activities along with examples from Wal-Mart’s case study: Production- No self-production, acting as a retailer Production Management- Inventory management Quality Management- Extensive IT network and huge workforce Marketing & Sales- Sales teams dealing with suppliers General management- store management, venue management Marketing and sales management- Sales team heads dealing with suppliers in a particular industry Accounting and Finance- In-house finance department performing general accounting, forecasting etc. Res earch and development- Constant acquisition of market intelligence and tools to make IT its niche. Human Resource Management- Extensive handling of employees’ daily attendance, payroll, deployment etc (IMA, 1996). 7) Out of all the above mentioned activities, production management is the most important activity. Although Wal-Mart is a

Review Paper on Fault Tolerance in Cloud Computing

Review Paper on Fault Tolerance in Cloud Computing A REVIEW PAPER ON FAULT TOLERANCE IN CLOUD COMPUTING Deepali Mittal Ms. Neha Agarwal Abstract— Cloud computing demand is increasing due to which it is important to provide correct services in the presence of faults also. The Resources in cloud computing can be dynamically scaled that too in a cost effective manner. Fault Tolerance is the process of finding faults and failures in a system. If a fault occurs or there is a hardware failure or software failure then also the system should work properly. Failures should be managed in a effective way for reliable Cloud Computing. It will also ensure availaibility and robustness .This paper aims to provide a better understanding of fault tolerance techniques which are used for managing faults in cloud. It also deals with some existing Fault tolerance model. Index Terms— Cloud Computing, Fault Tolerance, Dependability. I. Introduction Cloud computing is new method which can be used for representing computing model where IT services are delivered via internet technologies . These have attracted millions of users. Cloud storage not only provide us the massive computing infrastructure but also the economics of scale. Such a trend, requires assurance of the quality of data storage services which involves two concerns from both cloud users and cloud service providers: data integrity and storage efficiency. It is much more simple than internet. It is a service that allows user to access applications that actually exist at location other than user’s own computer or other devices on network. There are many benefits of this technology. For example any other company hosts user application. Cloud computing is nothing new as it uses approaches, concepts, and techniques that have already been developed. But on the other side everything is new as cloud computing changes how we invent, develop, deploy, scale, update, maintain, and pay for applications and the infrastructure on which they run. Cloud Computing is an efficient way of computing as it centralizes the storage, memory and processing. Fault tolerance has the property to assess the capability of the system to react graceciouslly to a hardware and software failure which is not expected. In assortment to attain robustness or raptness in cloud computing, failure should be determined and handled carefully.This paper will give basic knowledge about Fault tolerance Approaches.The Methods used for fault management in cloud We also study some existing fault management models which tolerates fault in cloud environment. Then figure out the best model of fault tolerance. Fault tolerance deals with all different approaches that provides robustness ,availaibility and dependability .The major use of enforcing fault tolerance in cloud computing include recovery from different hardware and software failures, reduced cost and also improves performance . Robustness is the property of providing of with an accurate service in an unwanted situation that can arise because of an unexpected system state. Dependability is something that need to be achieved.It is one of the very important aspects for cloud provider.It includes dependability as well as availability.It is related to some of the Quality of service issues delivered by the system. Fault tolerance intent to accomplish robustness and dependability in the cloud environment.Fault tolerance techniques can be classified into types depending on the policies of fault tolerance viz, Proactive Fault Tolerance : Proactive fault tolerance simple means early prediction of the problem before it actually arises. Reactive fault tolerance: This policy handles the failure. The effect of failure is reduced when the failure actually occurs. This could be further divided into two sub-procedures : 1. Error Processing 2. Flaw Treatment The first process eliminates error from the system. Fault treatment tries to prevent faults from getting reactivated . Fault tolerance is accomplished by error processing. Error Processing has two main phases. The first phase is â€Å"effective error processing† which means bringing the effective error back to a latent state and if possible it is done before occurrence of a failure.The Second Phase is â€Å"latent error processing† which aims to ensure that the error is not reactivated. II. Existing Fault Tolerance Approaches In Cloud The different techniques used for fault tolerance in cloud are : Check pointing: It is a good fault tolerance approach .It is used for applications which have a long running time. In check pointing technique , check pointing is done after each change in system state. It is useful when a task is not able to complete. It fails in the middle due to some error. Then that task is made to begin from the most recent check pointed state instead of restarting it from the beginning. Task Migration : There may be a case when a task in not able to complete on the assigned specific virtual machine . When this type of task failure occurs then that task could be moved other machine. This can be performed by using HA-Proxy. Replication: Replication simply means copying. The replica of tasks is executed on distinct resources if the original instance af task fails.It is done to get the actual required result. Replication can be implemented by using various tools. Some of the tools are Hadoop , HA Proxy or Amazon EC2. Self- Healing : A big task can divided into parts .This division is done for better performance. It results in creation of variant application instance.The instances run on distinct virtual machines.In this way automated failure management is done for instances. Safety bag checks: This strategy is quite simple. It blocks the command which does not met the requirements for safe execution or proper working of machine. S-Guard : It is a stream Processing techniques.It makes available more resources. It use the mechanism of Rollback recovery. Check Pointing is done Asynchronously. It is used for distributed environment. S-Guard is performed using Hadoop or Amazon EC2. Retry : A task is made to execute repeatedly .This approach try to re execute the failed job on same machine . Task Resubmission : A task failure can make the complete job also fail. So when a failed task is identified ,it should be submitted to same or either distinct resource for reexecution. Time checker : Time checker is a supervised technique. A watch dog is used. It consider Critical time function. Rescue workflow : This strategy is used for Fault tolerance in workflow execution. Reconfiguration: The configuration of the system is changed in this technique.The faulty component is removed. Resource Co-allocation: It increases the availability of resources. It takes care of multiple resources. Resource allocation is done to complete the execution of task. III. Fault Tolerance Models Various Fault Tolerance Models are designed using these techniques. These techniques are combined with one another and then applied or simply used individually. Some of Existent fault tolerance models are : â€Å"AFTRC A Fault Tolerance Model for Real Time Cloud Computing† is designed by keeping the fact in mind that real time systems have good computation. These systems are also scalable and make use of virtualization techniques which helps in excuting real time applications more effectively.This model is designed by considering the dependability issue. The model make use of proactive fault strategy and predicts the faulty nodes. â€Å"LLFT Low Latency Fault Tolerance † act as a middleware for tolerating faults. It is useful for distributed application which are running in cloud. In this model fault tolerance is provided like a service by cloud providers. Applications are replicated by middleware. In this way replication helps in handling of faults for different applications. â€Å"FTWS Fault Tolerant WorkFlow Scheduling† is a model based on replication approach. It also makes use of resubmission technique. A metric is maintained for checking the priority of tasks and they are submitted accordingly. The principle of workflow is used in this model. Workflow means a series of task executed orderly. Data dependency decides the order. Fault management is done while the workflow is scheduled. â€Å"FTM† is one of the most flexible model. It delivers fault tolerance as on demand service. The user has a advantage that without having known the working of model ,they can specify the required fault tolerance. It is mainly designed for dependability issues. It consists of various components. Each component has its own functionality. †Candy† is component base availability modeling frame work. It is mainly designed for availaibility issues. System modelling language is used to construct a model from specifications. This is done semi automatically. â€Å"Vega-warden† is a uniform user management system. It creates global work space for variant applications and distinct infrastructure.This model is constructed for virtual cluster base cloud computing environment to overcome the 2 problems: usability and security which arise from sharing of infrastructure. â€Å"FT-Cloud† has a mechanism of automatic detection of faults.It makes use of frequency for finding out the component. â€Å"Magi-Cube† is a kind of architecture for computing in cloud environment.It is designed for dependability,expenditure and performance issues.All three issues are related to storage.This architecture provides highly reliable and less redundant storage. This storage system is done for metadata handling.It also handles file read and write. IV. Fault Tolerant Model for Dependable Cloud Computing Fault Tolerant Model for dependable cloud computing is a model designed for dealing with failures in cloud . As we all know Cloud Computing Environment is made up of virtual machines or you can say nodes. The applications run on these nodes. Using this model faulty nodes are detected and replaced by correctly performing nodes. This is done for real applications. Now on what criteria the model can decide a node to be faulty ? There can be various parameters for detecting faulty node but this model makes use of dependability or dependability measurement. The criteria could be changed according to user’s requirement. A. Working of Model The model is designed for X virtual machines. X distinct algorithms run on the X nodes. Input buffer feeds the data to nodes. The input data is then moved onwards to all the nodes simultaneously. When the node gets the input it starts its operation. It performs some functions as designed or stated by the algorithm . In other words , the algorithm runs on nodes and gives a result .The Funtioning of every module is different. Accepter Module This module tests the nodes for correct result. It verifies the result of algorithms. If the result is faultless or as required then the result is forwarded further for evaluation of dependability.The appropriate result is sent to timer module. The inappropriate result is not forwarded instead signal is sent. Timer Module This module has a timer set for every node .It checks the time of result.If the result is generated before the time set or within that assigned time the only it forwards the result. Dependability Assessor This module is responsible for checking of dependability of nodes. At the starting of system the dependability for each node is set to it maximum that is cent percent. When computations are performed the dependability of nodes dynamically changes.The dependability is decided on the basis of time and correctness of result. Dependability increases if the result is accurate and on time. The highest and lowest limit of dependability is set in the beginning. The node with dependability value less than the lowest dependability is replaced. It also sends a message to resource manager. The result of dependability assesers forwards the results to descision maker module. Decision Maker It gets the result from dependability assessors. A selection of node is done from all perfect nodes. The node which has the maximum dependability is selected. It makes the comparison between the dependability level of nodes and system dependability. System dependability is important to be attained by a node. In case all the node fails to achieve the system dependability then a failure notification is issued. A failure notification means that all the nodes have failed for this computation cycle. Now backward recovery is done using check points .Decision maker also asks the resource manager to replace the node with lowest dependability with the new one. Check Pointing Check Pointing saves the state of system. It is done at regular small intervals. It is helpful in a scenario when a system fails completely. The strategy helps in automatic recovery form the check pointer state. This automatic recovery is done only when all the nodes fails. The system continues to work properly with rest of the nodes. Fig .1.Fault Tolerant Model For Dependable Cloud Computing B. Mechanism Of the Model Dependability Assessment Algorithm Begin Initially dependability:=1, n :=1 Input from configuration RF, maxDependability, minDependability Input nodestatus if nodeStatus =Pass then dependability := dependability + (dependability * RF) if n > 1 then := n-1; else if processing node Status = Fail then dependability: = dependability – (dependability * RF * n) n: = n+1; if dependability >= max Dependability then Dependability: = max Dependability if dependability Call Add new node ( ); End Decision Mechanism Algorithm Begin Initially dependability:=1, n :=1 Input from RA nodeDependability, numCandNodes Input from configuration SRL bestDependability := find_dependability of node with highest dependability if bestDependability >= SRL status := success else perform_backward_recovery call_proc: remove_node_minDependability call_proc: add_new_node End C. Result In the first cycle, both VirtualMacine-1 and VirtualMachine-3 have the same dependability, but the result of VM-1 has been selected as it has a lower IP address. VM-3 output was selected by DM from cycle 2 to 4, as it has the highest dependability among competing virtual machines. In cycle 5 VirtualMachine-3 still has the highest dependability, but it is not selected. Because its result was not passed by AT and TC, so consequently, it was not among competing virtual machines. TABLE I : Result v. Conclusion and future work Tolerance of faults makes an important problem in the scope of environments of cloud computing. Fault tolerance method activates when a fault enters the boundaries i.e theoretically these strategies are implemented for detecting the failures and make an appropriate action before failures are about to occur. I have looked after the need of fault tolerance with its various methods for implementing fault tolerance. Various called models for fault tolerance are discussed .In the present scene, there are number of models which provide different mechanisms to improve the system. But still there are number of problems which requires some concern for every frame work. There are some drawbacks non of them can full fill the all expected aspects of faults. So might be there is a possibility to carried over the drawbacks of all previous models and try to make a appropriate model which can cover maximum fault tolerance aspect.

Aphasia: A Language Disorder :: Biology Essays Research Papers

Aphasia: A Language Disorder "My most valuable tool is words, the words I can now use only with difficulty. My voice is debilitated - mute, a prisoner of a communication system damaged by a stroke that has robbed me of language," stated A. H. Raskins, one of approximately one million people in the United States who suffer from aphasia (1), a disorder which limits the comprehension and expression of language. It is an acquired impairment due to brain injury in the left cerebral hemisphere. The most common cause of aphasia is a stroke, but other causes are brain tumors, head injury, or other neuralgic illnesses. Of the estimated 400,000 strokes which occur a year, approximately 80,000 of those patients develop some form of aphasia (2). Another important observation is that within the United States, there are twice as many people with aphasia as there are individuals with Parkinson's disease (2). Yet, what is so astounding is the lack of public awareness about aphasia. Aphasia attacks an intricate part of a person' s daily life - the simple act of communication and sharing. The disbursement of such a tool deprives an individual of education learned through their life, often leaving the ill fated feeling hopeless and alone. In considering the effects of aphasia, a deeper analysis of the two most common forms of aphasia will be examined: Broca's aphasia and Wernicke's aphasia. While both forms occur usually as a result of a stroke in the left hemisphere of the brain, their particular site of impairment produces different side effects in an individual's comprehension and speech. These regions have been further studied through experimental researches such as positron emission tomography (PET). Moreover, although there is currently no cure for the disorder, there are treatments and certain guidelines to follow when encountering an aphasic. In physiological terms, Broca's aphasia and Wernicke's aphasia occur in the left hemisphere of the brain, which is responsible for controlling the right side of the body along with speech and language abilities. Broca's aphasia affects the frontal lobe adjacent to the primary motor cortex, and Wernicke's aphasia affects the posterior portion of the first frontal lobe (3). A general distinction made between the two disorders are that Broca's aphasia limits speech, while Wernicke's aphasia limits comprehension. Broca's aphasia characterizes patients as people who has loss the production of complete sentence structures in speech and writing. Although the individual may retain the usage of nouns and verbs, the aphasic may have lost all forms of pronouns, articles, and conjunctions (3).
