The Role and Authenticity of Wikipedia - Essay Example As the paper outlines, the example of Wikipedia, an online information source, can be deemed as vital to understand the importance of media, especially in the field of research. It has been observed that Wikipedia is an internet-based encyclopedia that works on the principle of collaborative editing. The source provides information to internet users all over the world in different languages. Furthermore, analyses suggest that since its inception, this internet-based encyclopedia has been providing more than 30 million articles in over 200 distinct languages to its users all around the world. However, the authenticity, as well as the reliability of this source, has been under the scanner, especially on the grounds of authenticity (Clark, â€Å"Wikipedia: What Is It Good For?†). This thesis will, therefore, present an argumentative essay which will adopt both supportive as well as criticizing stand on the authenticity and the role of Wikipedia in supporting the modern day resear ch needs. The presence of online published sources is enhancing with every passing day in various fields including research; may be academic or business oriented. The ability of these sources to provide information about every topic and in distinct languages has gathered popularity from millions of users all around the globe. Concerning these features, the position of Wikipedia can be considered as exemplary which further places it among the successful internet sites used to gather adequate information regarding a vivid range of topics and aspects. However, the biggest threat for the source in its successful operation has been the increasing criticism it faces on the basis of authenticity and reliability of the information published in comparison to other academic and peer-reviewed sources. This is owing to the fact that this internet source renders due significance to collaborative editing by engaging its users which is again not restricted on the basis of any particular eligibilit y criteria. In simple words, anyone who has the desire to share their knowledge regarding any topic can use Wikipedia as a platform; not only to publish new information but also to edit the previously published data. Thus, the high possibility exists for the data, published in Wikipedia in an editable form, to be exaggerated. The source does not demand any sort of expertise from the editors or neither has it set any sort of criteria for the users to express their knowledge through the source. Owing to its principle of being open for editing, the information provided by the source is often considered to be unreliable and unauthentic. Besides, the source can also be criticized on the basis of the fact that some of the information edited or provided by the users involves maximum plagiarism, i.e. the information published by unauthorized editors are often copied and pasted from other sources which again increases the risks of infringement of intellectual rights held by the publishers of that information. Consequentially, the information cannot be considered authentic as well as a quality work to support a research process, especially in an academic field. The source is also criticized due to the fact that much false information is being embedded in most of the articles published through Wikipedia and similar sources in the absence of any rules.  

Role of National Security in Pakistan

Role of National Security in Pakistan Pakistan had its first ever created national security policy from the day of its independence. At this stage it is important that Pakistan formed a comprehensive plan for the government for next five years to over come the difficulties of terrorism and low economic condition. Also the increasing terrorism in Pakistan has some severe issues on its national security. Much of the loss Pakistan faced in the previous some decades was due to the terrorism which is increasing day by day. This security policy is very significant in formulation because it shows a great effort to over come the situation of terrorism and we need a strategy plan to eliminate the security issues existing in our country. That internal policy made into soft component and hard component are comprehensive responsive plan (CRP) and composite deterrence plan(CDP) , respectively. These are set to combat against the threats to internal security. It is also criticize on some occasions but as a whole it is significant that the NSP is essential for this situation in Pakistan. What Is National Security? After the world war 2 , the different countries wants to be stable condidition in their countries. While their internal and external relations are not well.they are not advocated properly and need some kind of security measures to improve the condition of their relations with others. So in view of these instability America made its first policy which ensures their security measures at best level. Thus they made a council to take some serious steps in terms of their security making institutions.[1] In this way it is become the important factor to formulize the internal as well as external security policy for a better long term relations with others. What’s Included In National Security Policy? The national security policy (NSP) is not limited to the extent of security measures of a state. Thus it is now a wider term comprises of: economic , social , political and military strategy was well as the foreign policy. The secret agencies work under the government to uphold the situation of peace in the country and save it from the internal and external threats. As for a progress of a country it is essential for it that it hold a strong command over its economy and also its political structure be in democratic way transerfer from one to other in a fair manner. As terrorism is a fact who mostly mostly affected many of the countries and especially of the countries in which we live. The danger to our country lies in the policy making of our country and also the alliencies to which we are sided and on what basis we support them. Thus the national security policy determine our future and had a significant role in a countrys progress. Why Is There Any Need Of National Security Policy? One may asked that what so important in national security policy that’s it is essential for our country. The answer is very simple that from the day of independence Pakistan face issue of its existence. As in those days india is not ready to accept independence of Pakistan that’s why Pakistan has always a threat form india over its existence. Also india behavour over the neccession of states and war of 1948 , Pakistan has always a defensive position and had serious threats from some aliens force that’s why its impact on pakistans policy always remains. The Kashmir issue and Afghanistan role in 50s over independence of pakhtonistan become the hurdles in pakistans security threats and for that reason Pakistan has always remain in a defensive position. Also the increasing terrorism in Pakistan has some severe issues on its national security. Much of the loss Pakistan faced in the previous some decades was due to the terrorism which is increasing day by day. Due to instability of politics of Pakistan the democracy didn’t perform well and thus major decision were made by the dictators in Pakistan,for which Pakistan still faces crisis in every field due to improper planning. [2] The military intervention in Pakistans politics proves so fatal that its consequences are still observed in multiple forms. Thus due to these factors the national security didn’t operate well or didn’t made it to the required level. And Pakistan always faced crisis over Kashmir issue and in afghanistans issue. Emergence Of National Security Policy In Pakistan The concept of NSP arose in the regime of general yahaya khan who recommendation of the admiral ahsan formed a national security council (NSC). A NSC is formed to update the president and prime minister directly. Its main function os to provide the basic information on internal security. This NSC is dissolved by zulfiqar ali Bhutto and defense committee of cabinet (DCC) was created in its place. Then it is reconstructed by general zia ul haq. After this is remain in active for a long time as it is dissolved by DCC again by Benazir Bhutto. After that it is made active by general pervaiz musharraf in 2004 in which he made tariq aziz a civil bureucreat the secretary of NSC council. It worked for a long time unless in 2008 when ppp convert it into DCC agsin. The reason for not working properly this NSC was that it is always involved in the politics and help military to take over the civilian governments due to the members of its which are mostly from the retired military officers and bureucreats. That’s the reason it is become unfavourite for The civilian government and they always against this because they take care of the politics and not concern in making national security policy. Re-Construction Of NSC In Nawaz Regime 2013 As the nawaz sharif won the election of 2013 by majority seats of national assembly and formed a government in the center he thus made the sartaj aziz secretetary of national security council on june 2013. They greatly emphazised by the interior minister to formulat the national security policy in order to come over the terrorism situation in Pakistan. The interior minister ch. Nisar greatly contribute in the formulation of national security policy whose efforts are came up with the NISP of Pakistan and then presented to the NA of Pakistan to passed it but was delayed due to some improvements in it. This security policy is very significant in formulation because it shows a great effort to over come the situation of terrorism and we need a stretagy plan to eliminate the security issues existing in our country. Draft of national security policy for 2013-14 in Pakistan: The policy introduced by government of Pakistan comprises over three parts i,e Strategic Operational Secret There is some problem with this type of division because it is difficult to understand as it is comprises over some secret information which is not shareable with the public but it is appreciated that it is on such issues which are key factor for this policy.[3] It includes sovereignty of Pakistan and according to it the peace talk to stakeholder can be only one condition that the isolation of extremist from alien agencies funding. The NISP is formed due to the global terrorism in the whole of world and also the issue of Afghanistan and its effects to the pakistans security. Also focuses on the elimination of extremism, sectarianism , terrorism and militancy from our country and an adequate planning on it. The NISP also includes the internal security especially , but also focus on external security and strategy to come over such threats. This will remain included in the ministry of defense jurisdiction. The focus on other issues such as social , economic , environmental and political issues also included in the draft. Civil liberty emphasis in National security policy and ensure their safety. The threat perception as Pakistan face some serious extremism on its social and economic level. Also to break the shadow linkage of these organizations. Also to maintain writ of state. Ensures fundamental rights of people. As said earlier that internal policy made into soft component and hard component are comprehensive responsive plan (CRP) and composite deterrence plan(CDP) , respectively.these are set to combat against the threats to internal security. The first component of CRP comprise on peace talks and also the rehabilitation of the victims of terrorism. The programme of reconstruction of those institutions affected by the terrorism are monitor by NACTA. NACTA will develop de-radicalisation with help of NISP. NACTA will also started a reconciliation with consultation of various groups for peace building process in Pakistan. The re-integration process provides people to improve their economic condition by applying Youth Engagement Strategy (YES). It also improves the educational madrassas system by supporting them in their finance and administration system. The NISP will also focus to come up with certain legal reforms in our legal system to improve the judicial system as well as ensures fundamental rights of people by courts. NACTA represents the reports on how to improve the prosecution , judiciary and police etc. Composite deterrene plan (CDP) will allow many national internal security apparatus to work properly and provides them full technique help on all issues. The NISP also improves the national internal security institutions. An awareness to people is given to stop the extremism , sectarianism and terrorism through media , civil society. The implementation on the de-radicalization also included so that the rehabilitation may acquire upto a desire level. A proper gateway to monitor madrassas and religious institutions at federal and provincial level. Improve the situation of socially and economic of terrorism affected areas at federal and provincial level. The rehabilitation of children , women and minorities must be ensured. The places of national heritage must be preserved under a specific policy. Steps should be taken to de-ammunize the cities. Steps should be taken to evoke the misuse of media , social media and reforms on issuance of new mobile sim. The cybercrimes prohibited and take measures against it.[4] Improve national database system so that the identification of people and evaluaton on their assets be ensured. The measurement on the problem of afghan refugees and control their movement under the law. Steps taken to stop the smuggling in country and improvement in border line security. An agency of directorate of internal security (DIS) is made which will work under NACTA. This agency had 33 members which are from civilians as well as from military men who works together to conduct intelligence on internal security. This will eliminate terrorism from country and also ensures public safety. There should be a federal rapid response force (FRRF) with counter terrorism department (CTD) which works in Capital Terroritery , FATA , Azad Kashmir and Gilgit Baltistan with their unique coordination and command. Beside this there should be a provincial rapid response force (PRRF) with CTD also exist at provincial level. Also taken measure for the destruction of biological weapons and its use is prohibited. The international cooperation is required to control global terrorism and also their coordination. All agencies report issues to NACTA within 30 days limit. The information is also provided to ministry of defense under which they work and provide them with full information where required . Also the information from public required and suggestions are invited through intelligence and media. These suggestion are improved NISP by NACTA. Implementation Of The National Security Policy The implementation of the NSP is ensured by the counter terrorism department CTD with the help of police and other institutions of the type because the coordination and proper cooperation it is not implement. The police will help the DIS to gather information and present it to the national internal security operation center (NISOC) for further improvement in NSP. The police shall establish a specialized counter terrorism department for their help and maintenance and establishment of weapons and machinery exist according to NSP.[5] The facility of air flight emergency shall provided to these institutions. Good Intentions In National Security Policy The NACTA is an important step by the government as this NACTA (National Counter Terrorism Authority) is linkage between federal and provincial level and also between the security agencies because the lack of coordination can result in very drastic condition of security issues and face crises after this lack of coordination. Reforms in madrassas also appreciable. Cooperation between civil and military institutions Issue of afghan refugees Cooperation between federal and provincial level Action against cybercrimes Formulation of RRF(rapid responsive force ) Fundamental Rights of people Process of rehabilitation , reconciliation and reconstruction of terrorism affected areas Isolation of terrorist Criticism On National Security Policy Some of the issues are criticize in the national security policy of Pakistan and also some suggestions are given to government on this draft which are as follows: As the policy divides into three parts that is strategic , operational and secret so the classification or justification of issues become so confused that one may not defined them in proper category. The draft as said the extremism , sectarianism , terrorism and militancy division but the document need some explanation on their difference so that people should aware properly in this respect. As civil liberties are ensured but there is not a comprehensive legal regime in this respect and need a committee of jurist to overview the legal system. Also the disputes are peacefully solve under the rule of law but the extremist didn’t admit rule of law of state so what will the basis for the talks with the stakeholders are need to be improve. There are also some protection on comprehensive response plan CRP and combined deterrence plan CDP and need some justification on such issues. The cooperation between the federal responsive force RRF and provincial responsive force exist but what if they are not agreed on the cooperation. Instead of making the counter terrorism department the reforms shall be introduced in the police and made CTD under the police so that the security issues can be made better.[6] Also the security institutions need some men with brains not with guns and officials should be involved in the field of communication , forensic , lawyers , and financial experts etc. In short there may be some flaws in the national security but its significance can not be denied at all and it’s a good step taken by government. Nowadays as there are concept of global terrorism and without a strict cooperation between institutions the peace situation can never be achieved. So for a peaceful environment these steps should be taken at all cost. This NSP hope best prove for our country and we achieved a situation of law and order in our Pakistan. It is also criticize on some occasions but as a whole it is significant that the NSP is essential for this situation in Pakistan.

INVESTIGATING THE ECOLOGICAL NICHE OF THE CRAB USING A FAIR TEST INTRODUCTION: The ecological niche of the crab Hemigrapsus edwardsi. The crab is a member of the Crustacea phylum and is in the family Grapsidae. This crab species is found only in New Zealand on rocky shores. The rocky shore, where the crabs studied in this investigation were found is quite exposed. There is a large rock platform that provides small crevices and small rocks which help to protect them from wave action and predators. There are also sea lettuce, and other algae growing on parts of the rocks.The crab has many adaptations that allow it to live on the rocky shore including: †¢ grey/black colour for camouflage †¢ food detection structures (antennae on its head and hairs on the mouth parts to sense chemicals in the sea water) †¢ 4 pairs of legs with muscles that allow it to move sideways, as well as forwards and backwards †¢ behavioural adaptations such as scuttling under rocks when the tid e goes out or to avoid predators †¢ freezing when being attacked (we noticed this when we touched some of them on their backs). This might confuse predators. †¢ gills for gas exchange.The rock pools provide a micro-climate where the temperature and salinity of the water will change, depending on the weather. If it was a really hot day, the rock pools will get warmer, more water will evaporate and the salinity will increase. The crab would have to be adapted to cope with these changes in salinity, otherwise, as the concentration of salt in the water around it changes, it will gain or loose mass due to osmosis. Through the process of osmoregulation, the crab is able to maintain a constant water balance in its body, but to do so requires energy and this could be measured by an increase in the respiration rate.This is what I am going to investigate. Aim: To determine whether the respiratory rate of the crab changes in different salinities. Hypothesis: The respiratory rate of t he crab will increase as the salinity changes away from â€Å"normal† salinity. METHOD Thirty crabs of similar size, were collected from the rocky shore. The salinity was varied by diluting the 200% conc. seawater provided in to five different concentrations. The volume of the solutions was 200mL each. The concentrations were 150%, 125%, 100%, 75%, 50% conc. Water with 100% concentration is equivalent to the concentration of normal seawater.Sixty-five mL of the 150% solution was poured into a petri dish. The petri dish had a thin layer of stones in the base to recreate the natural environment of the crabs. One crab was put into this petri dish and left for five minutes to allow them to adjust to the conditions. The petri dishes were floated on a water bath which was set at 180C. The water bath was placed in the room where the light intensity was the same for all petri dishes. An indirect method of estimating respiration was used. This was to count the number of currents seen on the surface of the water.I assumed that a higher number of currents indicated a higher respiration rate. A little bit of carmine red was sprinkled onto the solution in the petri dish in order to see the movement of water more clearly. The crabs were left in the petri dishes for five minutes before counting the respiratory currents. The respiratory currents were counted for 30 seconds. This amount was doubled to give the rate per minute. 5 more trials with different crabs were done at each concentration. Each time a fresh 65 mL of solution was added. The results were recorded and the rates per minute were averaged.This process was repeated for the 4 remaining concentrations and the results for these were averaged. Results: Average respiratory rate of the crab in different concentrations of seawater. | |% concentration of the water (100% = normal sea water) | | |50 |75 |100 |125 |150 | |Average number of respiratory | | | | | | |currents per minute |7. 2 |6. 75 |6. 00 |7. 50 |12. 4 2 | Average respiratory rate of the crab in different seawater concentrations. Statistical analysis of results: The graph of the results suggests that there is a significant relationship between the concentration of the seawater and the respiratory rate of the crabs. This is confirmed by the r2 value of 0. 9642, which indicates that 96% of the variation in the results is explained by the change in seawater concentration. Conclusion:The respiratory rate of the crab, as measured by respiratory currents, increased when the concentration of the seawater either increased or decreased from the 100% conc. (normal seawater). Discussion: This investigation was carried out to determine whether respiratory rates of the crab increased as the salinity was changed from normal levels. The crab is a euryhaline organism that lives on the rocky shore, often in rock pools. Because of the tidal movements of water, the salinity of the crab’s environment fluctuates. To maintain homeostasis, the cr ab osmoregulates.This means it actively controls the salinity levels inside its body. As the seawater concentration increased or decreased from the concentration of normal seawater (100% conc. ) the respiration rate increased. This is because the crab is most comfortable at the concentration of normal seawater. As osmoregulation involves the active transport of ions, it requires energy to adjust to higher or lower seawater concentrations than 100% seawater. As the salinity of the crab’s environment increases or decreases from the salinity of normal seawater it requires more energy in order to osmoregulate.So in order to obtain that energy, it needs more oxygen and its respiration rate increases. This is necessary for the crab as it must deal with a range of salinity as the tidal pools dry out. If the concentration of the water is greater than that of the crab’s internal environment, it will go through osmosis. Although the crab has an exoskeleton, water can still leave its body through the space around its joints and gills. Evaluation: Initially I found that there were several problems with my investigation.The most significant one was that the crabs were out of their natural environment which made them more fidgety. Some of mine even attempted to escape from the petri dishes during the trials. This clearly shows that they were unsettled and perhaps not responding as they usually would. If they decided to stay inside the petri dish, they stayed close to the edge and moved away from the movement of people around them. I moved my investigation to a more secluded position and screened them off with a cover so that were not able to see what was around them.I also lined the petri dish with a thin layer of stones to attempt to somewhat recreate the natural environment. This change made the crabs calmer and produced a more natural response. The counting of actual respiration itself was difficult as it was a humid day and the carmine red seemed to be con gealing before being placed in the water. Perhaps in humid conditions chalk dust or very fine sand would have been more suitable but these were not available where I was carrying out the investigation.Where the crabs were sampled from may have biased the outcome of the results as the position in the tidal zone might influence the levels of salinity that they were accustomed to. Most of my animals appeared to be female, this may also have biased my results. Further investigations would need to be carried out to determine if sex or original location influences crab respiration rate. Despite these limitations my results show that the increase in respiratory rates can be explained by the changing concentration of the seawater. ———————–INTRODUCTION ECOLOGICAL NICHE AIM HYPOTHESIS Explains aspects of the ecological niche that are related to the investigation.

Your task is to research possible organizational structures that best suit the needs of your clients and your organization. I think that our services for domestic abuse patients should be split into different departments for several reasons. Departments make people focus on only the work that is assigned to them, like getting people to the Human Services help for a first step, then sending them into counseling, and finally getting them rehabilitated and out of the system. Other approaches to department and service areas exist, like having a north segment and a west segment to divide responsibilities. The major disadvantage to departmental division is that you might lose track of a client, or just lose contact with them when they move out of your department. People who need these human services need extra individual attention, not a rabble of people that they have to talk to while they get help. The situation is almost the same for a matrix organization. Yes, it is more efficient to have several people working in one area, but the client will not get particular help from one person, which is important for these clients. I truly believe that Human Service work should be leading in a transformational style. I think that, for us, the Project Team model is the best way to organize our services. This model is the best one because a group of people works together to accomplish particular things for their client. They all communicate inter-group, and therefore everyone gets better at helping clients. One problem with this model is that team members might start to discuss their client in a way that would break confidentiality laws. A collegial model is another approach, and it raises understanding because employees report their affairs to you, which keeps people enthusiastic about their tasks. This way is also an option, but I think that it might lead to employees doing things only to please a manager.
