Evaluation of Sociological Theories Essay -- Papers Sociology Deviance

Evaluation of Sociological Theories Deviance can be described as: "Nonconformity with existing/traditional social norms. This nonconformity is often said to be pathological when it challenges power and privilege; yet it is said to be indicative of innovation or creativity when the gatekeepers of morality approve it. A loaded term, deviancy is a negative asset when the environment is stable but can be a positive asset to a society when the environment is irreversibly changing." Each perspective asks different questions and focuses on different issues regarding crime and deviance. They have different ideas about the causes of crime. Subcultural theories on crime and deviance were developed in the late 1950s and early 1960s from the works of Albert Cohen(1955) and Richard Cloward and Lloyd Ohlin(1960). They suggested that people react to forces 'external' to them, this leads them to behave in certain ways. Their behaviour is determined by social causes. Criminals behave differently from non-criminals. Subcultural theorists have attempted to seek the causes of these differences, they claim to have identified malfunctions in the social order. These malfunctions are seen to be rectifiable by different types of social engineering e.g. Social reform, social welfare and education. Crimes are 'social facts' and therefore must have 'social causes'. Criminals are not seen as 'abnormal' individuals by subcultural theorists, but as social actors influenced by social causes. Statistics have indicated that criminals are mostly male, adolescent, working class and urban living. An idea inspired by Durkhiem (1952) suggested that this is a 'socia... ...s as it gives evidence to support their idea that working class people commit more crimes than middle class males. On the other hand, criminal statistics was challenged by left realists who believe that criminal statistics is the reality and therefore we should accept it, along with the solutions to attempt to solve the problems to tackle the high levels of crime. Marxist approach in explaining deviant behaviour is only reliable to some extent. Along with the contradictions from other perspectives, it shows that improvements can be added to their ideas. Marxists mainly concentrated on the class distribution and stress that they the ruling class control the norms and values of the society. It will not be classed as deviant unless the bourgeoisie say so and they will not say so unless a working class person commits it.

Enterprises with appropriate technology are having a definite advantage over the others in the competitive business environment. Therefore enterprises should have very clear understanding of their technology needs and opportunities. Many telecommunications service providers in the world are in the midst of undergoing tec hnical and structural changes, whilst at the same time experiencing major growth.Competition and rapid technological advancements drive the present telecommunications industry. In Sri Lanka Mobile Communication Industry is rapidly growing. More than 12 million Mobile users are in Sri Lanka. Following figure shows the mobile subscriber growth.

The economy having achieved sustained growth over three decades averaging nearly 5% per annum, in conjunction with a modest population growth in comparison to other South Asian countries crossed the USD 2000 mar k in per capita income. Notwithstanding conditions of uncertainty, investment in infrastructure development continued at the macro level and Mobile Communication industry has achieved a considerable growth.The economic realities and new market developments during the last year turned out to be a stress test for all mobile phone operators in Sri Lanka. Ruptures emerged and the industry had to search for quick but durable fixes to remain viable. The entry of the fifth mobile phone operator, early in the year set the new reference price and forced a downward revision of pricing by all mobile operators. This caused a sharp reduction of the reference price by approximately 50%. Further to cutting prices, competition in the industry intensified and this resulted in a sharp rise in advertising and promotional activity.The combined effect of a significant drop in prices and high promotional costs compelled most industry players to consider serious adjustments to their business models and st ructures, a process that led to job losses in the industry. Leading operators recorded some growth in business volume in a growing market, but declining margins eroded revenue bases leading to operating losses. 1. 1 Objectives Main objectives of this repot are; 1. Assess Technology Level of Sri Lankan Mobile Communication Industry 2. Identifying main technology issues in the industry 3.Proposing technological solution for those issues 1. 2 Methodology Literature survey was done regarding the Sri Lankan and world Mobile communication industry. In the second step responsible staff members were interviewed representing all five mobile operators. Their views and information collected from literature survey Page 2 Mobile Communication Industry in Sri Lanka were analyzed. In addition to above Mobile communication equipment vendors were contacted for gathering information about new technologies and trends. Page 3Mobile Communication Industry in Sri Lanka 2 Technology Level of Mobile Indust ry In order to examine the technology level and capability, framework developed by Panda and Ramanathan (1995) can be used. This framework is based on the value chain concept, which identifies the primary and support activities of a telecommunications service provider, and uses step by? step procedure to analyze the technological capability needs in these activities and to develop indicators to measure the extent to which such technology capabilities have developed. 2. 1 HistoryAlthough telecommunication has a history of more than 150 years in Sri Lanka, the island’s mobile communication history extends to less than 25 years. Mobile phone technology first evolved in 1946 after the Second World War. The first Mobile network was established in North America. After 42 years, mobile technology was introduced to Sri Lanka. The first private mobile operator to enter the market in 1989 was Celltel Lanka Limited, which was later known as ‘Tigo’. In 2009 Tigo was acquired by Etisalat; Middle East telecom giant. The first mobile operator based its services on the E?TACS technology which offered basic voice services to Sri Lankan subscribers. Between 1989 to 1994 the Government took measures to introduce competitive cellular services by granting license to three mobile operators; OTC Australia (Pvt. ) Ltd, presently known as Mobitel (Pvt) Ltd, MTN Networks (Pvt. ) Limited, commonly known as Dialog GSM, and Lanka Cellular Services (Pvt. ) Limited currently known as Hutch. In 2009, the Government introduced more competition to the market by granting license to a fifth mobile operator, Bharathi Airtel which is an Indian telecommunication giant.From 2004 to 2010 Mobile communication industry in Sri Lanka had an annual growth of around 35? 40%. 2. 2 Assessing Technology Level World Technologies in Telecommunication is shown in Table 2. 1. It can be seen in the world still there are network operating mobile technologies of 1st generation, 2nd Page 4 Mobile Communication Industry in Sri Lanka generation and 3rd generation. By looking at the subscriber percentages belong to the networks it can be concluded that 1st generation technology networks will not last much longer as already it is 0. 01 percent of world subscriber base.Technology GSM CDMA2000 1x WCDMA CDMA2000 1x EV?

As still GSM technology has more than 80% of world subscriber base and GSM is enhancing with support technologies it is expected to last more years. 3G/3. 5G (WCDMA/HSPA) are most modern commercially available technologies. It’s seen that these technologies are capturing the market rapidly. According to related surveys, more than 96% of WCDMA networks have deployed HSPA, with the majority (over 52%) supporting a peak downlink data capability of 7. Mbps or higher. With 22% of HSPA network operators committed to HSPA Evolution (HSPA+).

Also Sri Lanka is the first country which demonstrated HSPA+ in South Asia. Page 6Mobile Communication Industry in Sri Lanka 3 Technology Problems Recent years were probably the most challenging for the mobile communication industry in its history. Economic and industry turbulence heightened and industry leaders were forced to absorb the shocks in telling proportions while weaker operators were rendered vulnerable. The mobile communication industry deserves commendation for surviving trying economic, industry and regulatory challenges and for riding the tide. However, the cumulative effect was an entire mobile communication industry reporting operating losses.Following are some performance data of Mobile Operators in year 2009. Dialog Group reported negative NPAT of 1159 mill. Without recurring costs. In operation Etisalat reported a loss of approximately ~1600 mill. Hutch turn over was decreased by 61. 9% Mobitel reported a net loss of Rs. 395 mill. As margins become narrower and narrower operators are needed to find new opportunities in order to enhance revenue. But several technological problems are there as barriers for growing Mobile Communication Industry. 3. 1 Capacity Limitations In Mobile communication data traffic demand is rapidly increasing.Major bottle neck in providing higher data rates is limitations in transmission networks. Currently Mobile operators have not island wide optical fiber networks in order to provide higher capacities. Also to provide higher capacity at low cost, tradition al TDM based access networks are a barrier. So IP based networks need to be deployed. For this huge investments are needed but current financial status of all mobile operators is not healthy enough for that. Currently it is not possible to provide higher data rates when users move from UMTS (3G) coverage area to GSM/EDGE coverage area.Page 7 Mobile Communication Industry in Sri Lanka Currently the number of users can be catered by one cell has become a issue in mobile industry, because if there are more than possible no of users in the same cell, Users experience the congestion situation and as a result this cell need to be further brake in to two cells or covered by an umbrella cell to cater the capacity. When doing so different frequencies need to be assigned to the different cells and this will increase the interference to the users and quality would be dropped. 3. 2 Energy IssuesIn rural villages in Sri Lanka, electricity is either not available or is available only in limited q uantities. As a result, even if battery backup is provided for the Base Stations (BTS), the batteries do not get fully charged. Further, due to frequent interruptions in the power supply, the life of these batteries gets shortened, which in turn increases the operational cost to run services in rural areas. Unavailability of reliable power in semi? urban, rural and remote areas increases operational costs further because sufficient backup systems have to be maintained.Therefore sustainable green energy sources are essential to have need in future. But still in Sri Lanka Green Technologies like solar energy and wind power energy are not popular in Mobile industry. Also existing such technologies are not capable of successful operation of base stations. Unavailability of commercial power in rural areas is also affected to mobile operators to expand their coverage. Optional power sources are needed to expand coverage in small time duration with minimal cost. 3. 3 Frequency Spectrum Iss ues In Sri Lanka Super High Frequency (SHF) Band is highly polluted.SHF band includes frequencies between 3GHz and 30 GHz. In this band more than 10000 Microwave Links are currently operating. Especially in urban areas it is difficult to deploy new back bone microwave links due to interference. This has highly influenced for providing enough data capacity for Mobile Broad Band customers. Page 8 Mobile Communication Industry in Sri Lanka TRCSL has not allowed Point to Multi? Point backhauling technologies for telecom operators. With this technology number of microwave links need to be installed can be reduced and operators can easily deploy their back hauling networks. 3. 4 BSC/MSC BoardersIn early mobile systems, remote base station sites were controlled by the MSC or mobile switching center. But with current systems under 2. 5G GSM network BSC Base station controller controls the remote Base stations and under 3G network RNC Radio Network controller controls the remote node B sites , because of this scenario, It is a must to have several BSC/MSC boarders in the network and when users are moving via this boarders, the probability of drop of the calls are vey high reducing the network quality in those areas. For example, people in the boarder areas always experience call drops and bad call quality etc.Therefore improvement for this is necessary via the advancement of the technologies. It may be high capacity MSCs or BSCs or some other solutions. 3. 5 Tower Loading Microwave links are used as the main means of backhauling in mobile industry in Sri Lanka and these microwave links need to be fixed on towers with having line of sight. Usually each tower connects with more than one tower therefore always several links are need to be installed on a tower top. If its a hub site this number may increase to 10? 15 even more than 50 sometimes. Microwave antenna comes with 0. 6/1. 2/1. /2/2. 5m diameter; therefore this is a big equipment. Also it has a larger wind shield a rea, because of this big size and area and weight operators need high strength large towers to be implemented. If the antenna sizes and weight of this microwave links can be decreased it would be quite advantageous for the operators. Else new technologies like laser links, IR Links or smaller antenna sized IP links technologies can be developed to be able to guarantee the same level of availability. Then operators would be able to replace heavy microwave and use light equipment types. Page 9Mobile Communication Industry in Sri Lanka 4 Proposed Technologies 4. 1 Fiber Based Transmission Fiber based transmission is not a new technology in the industry. In Sri Lanka SLT and Dialog have their own fiber based networks. Fiber based transmission can cater quite high capacity data transmission. It can be used to implement either TDM/SDH based network or Packet/IP based network. Although SLT has a island wide fiber network, Dialog fiber network is still not widely spread. In fiber based solu tions fiber cables are drawn from core network sites to the remote Node? B/BTS sites.Usually a ring topology is used and it goes via hub sites, from hub sites fibers are drawn to remote sites. Figure 4. 1: Typical Fiber Based Mobile Network The problems with Fiber based transmission is the high initial capital investment cost and the time taken for the implementation. Most of the operators are not capable of affording such investment for their own fiber based infrastructure. Page 10 Mobile Communication Industry in Sri Lanka If a fiber network can be used for providing transmission for base stations, increasing data traffic demand can be easily fulfilled.Another option is to lease fiber network’s capacity from already deployed SLT or Dialog network. But leasing cost need to be highly considered. 4. 2 IP RAN Implementation of IP RAN (IP Radio access network) is the key to provide higher capacity. An IP ran with higher capacity to remote sites can reach higher speeds with curre ntly available HSPA+ like technologies. Figure 4. 2: HSPA Technology Roadmap According to the roadmap shown in Figure 4. 2, with the enhancements of HSPA+, Wimax /ADSL speeds can be passed or equalized with HSPA in the years to come.The IP radio access networks (IPRAN) consist of end to end (Remote sites to the core network nodes) transmission with IP/Ethernet networks. Easiest way to implementation of such a technology is fiber based IP network where higher capacity and less complexity can be achieved. 4. 3 EDGE Evolution for GSM Current 2G networks are inadequate for providing data speeds of GSM/EDGE networks. EDGE Evolution quadruples standard EDGE network speeds, promising downlink data Page 11 Mobile Communication Industry in Sri Lanka rates of 1. 2Mbit/s, though the standard has headroom for up to 1. 9Mbit/s.Similarly, uplink data rates of 474kbit/s are expected, although the standard specifies 947kbit/s. 3GPP standardized EDGE Evolution in 2007 (3GPP Release 7). 4. 4 Green Te chnologies Maintenance costs of networks in rural areas are high compared to urban areas, because of several factors such as poor transportation systems, difficulty in supply of spare parts and non? availability of skilled manpower. Due to lack of reliable power in rural areas, there has been a substantial increase in the usage of diesel for running engine alternators to keep telecom switching centers, transmission equipment and BTS s up and running.Currently more than 5000 Communication towers are there in Sri Lanka. This increases costs substantially. In spreading the reach of telecommunications in remote areas, renewable energy should be used to power relay towers in remote areas. By replacing diesel generators with solar panels in cell phone towers, tons of carbon emissions could be prevented from entering the atmosphere. Global Telecom emission in 2002 and estimated values in 2020 are shown in Figure 4. 3. Figure 4. 3: Global Telecom Emissions 2002 – 2020 Source: The Cli mate Group and Global e?Sustainability Initiative Page 12 Mobile Communication Industry in Sri Lanka Solar is a clean and effective way of harnessing energy. Also, the maintenance cost for the operation of solar equipment is comparatively lower as compared to diesel generators operated BTS towers. Solar generators have no carbon emissions and also help in preserving the environment for sustaining life on earth. It reduces global warming, as carbon emissions are null in solar devices. The manpower needed for the operation and maintenance for solar equipment do not require extra skill.The telecom majors in world have started operating mobile repeater and relay stations, which harness solar and wind energy with the wind turbines foisted on the telecom towers. The hybrid systems, involving solar photovoltaic systems and wind energy installations for this application assure uninterrupted supply of 2. 8 kilowatts of power daily. A master control installed at the site acts as a voltage sta bilizer, while a generator has been kept as a back? up for charging the batteries in case of emergency. Though the diesel generators are the lifelines of telecom towers, they contribute to significant carbon emissions.Going green and pushing the use of alternative energy sources like solar, wind and bio? fuel is the need of the hour; the government should provide high subsidies to help the telecoms taking this step, quickly and easily. Going solar is the way forward. Therefore as we can see above technologies are the candidate technologies for future enhancement of Mobitel network. According to the study these technologies can solve the main issues that were identified in this chapter. Therefore a strategy and a roadmap are required for timely implementation of the technologies in the network. 4. 5 LTELTE (Long Term Evolution) is a 4G technology which is emerging in the world now. When existing technologies are becoming obsolete, investments need to be done on new technologies. It i s assumed that 2G will become obsolete in near future. Page 13 Mobile Communication Industry in Sri Lanka Figure 4. 4: Envelope Curve of Mobile Technologies Figure 4. 4 shows the envelope curve of mobile communication technologies. It can be seen the technology is mainly improved focusing the deliverable capacity. See Figure 4. 5. Figure 4. 5 Expected Growth of Mobile Data Industry Mobile broad band services provide new opportunities for Mobile Operators.With LTE customer demands can be satisfied easily. Page 14 Mobile Communication Industry in Sri Lanka 5 Future Industry of Mobile Communication Current monthly operational cost of Mobile Networks is several folds higher than revenue which is the case in many technology introductions. By introducing green technologies operational cost can be reduced. Therefore a huge advantage can be taken in current price war. With low cost IP based technologies and Point to Multi Point Backhauling technologies can be reduce operation and maintenanc e cost also.Going for Fiber Networks can help to reduce operational cost by reducing huge TRCSL license charges need to be pay annually for Microwave Links. With those technology improvements turn over can be improved and hence investments can be encouraged because huge investments are needed in near future as Core Mobile Technologies are evolving day by day. Government need to be given intensives for investments in Mobile Technologies as it can energize the economy in return. Above mention technologies can reduce the environmental problems raised by Mobile Industry. Some of such issues can be listed as follows.Carbon Emission of more than 5000 Base Stations island wide Radio Frequency Pollution Currently Mobile Industry has influenced in culture also. Wide spread of pornographic contents is a major issue. Now recently all mobile operators have been agreed to implement technological measures to filter out such contents. Therefore by introducing mentioned technologies mobile operator will be able to overcome technological barriers as well as financial issues, marketing issues and environmental uses etc. Although Sri Lankan Mobile tariffs are the lowest in the region, customers are not satisfied with the service in general.This bad customer images Page 15 Mobile Communication Industry in Sri Lanka regarding mobile operators can be eliminated from the heart of the customers by introducing state of art, sustainable and low cost technologies. Page 16 Mobile Communication Industry in Sri Lanka 6 Conclusion Technology plays a vital role in any industry in today’s world. Mobile Communication industry is not an exception. Mobile Technologies are evolving very rapidly and customer expectations are also at sky level. In Sri Lanka 5 Mobile Players are operating in the industry and they use most popular and

Assigned Seating Essay

Would you want an assign seat for everyday you sit at lunch or would want to be able to choose for yourself? In our country we have always had a freedom of choice. The topic the I am going to discuss with you is wether or not you should have assign seats during lunch. Many middle school and high school students disagree on having assign seats. Many agree with it because it is a chance to make new friends or interact with someone you usually do not. I do not think that assign seating is the best way to have lunch when we need sometime to socialize,relax and talk with your friends. For one thing, students will most likely be comfortable when they are next to people they know already. 100% of sample students polled from a local middle school stating that they were in favor of having no assign seating in the cafeteria. After all,it is quite logical that kids will feel more comfortable when they are not fretting about other things. Also, having no assign seating prepares students for the real world. Letting students choose where and with whom they are seated in school prepares them for the future, where they will have to make responsible decisions based on what is best for them, which is one of schools main ideals, or at least should be. In addition, allowing freedom can give them a chance to interact with others. For example, if you had assign seating in your cafeteria you would have to sit next to the same person everyday and you would not be able to talk or interact with different people. Also, there was a kid that was in school that had assign seating and everyday at lunch he go bullied by a kid that was in his table, and because of that he tried to kill himself. Thousands of schools participate in this program and it was successful but not in the school that this poor kid went to. Finally, having the freedom to sit where you like can give you more time to eat. For example, if there is someone in your assign seat and your not the kind of person to get in trouble, you would have to stand there and wait until they move which can take a while and it takes time away from eating and relaxing. One time there was a kid that wanted to eat lunch when someone was in his seat and they did not move, so so the kid had to wait until the other boy moved from his seat and that took up his whole lunch break and he ended up not eating at all. Having assign seating with someone you dislike or do not get along with could end up in an argument or even worse, a fight. Some of the benefits of having assign seating are that kids will not continually wander around the cafeteria looking for a seat, and chocking back tears when no one would let them join a table. Also, the cafeteria would not become ground zero for gossip, bullying, and fighting. If we had assign seats there are many different advantages concerning the stop of bullying, fighting , and arguing. Now, should kids be able to chose there own seats? if they sit in school for 7 hours and do 2-3 hours of homework per night, and even have projects for the weekends, will they also refuse kids from sitting where they like in lunch? To me , assign seating is a definite no, and I strongly disagree with anyone who says that they agree with it.

Ashaba-Ahebwa Mark on Civil Law in the Ugandan Jurisdiction Essay

The place and mode of trial is usually determined by type of trial and proceedings. If you make an application by summons, then you will be heard in Chambers. Procedure 1 – where defendant elects not to call evidence The Plaintiff or advocate makes an opening speech referred to sometimes as an opening statement. After that the plaintiff witnesses are called, examined cross examined and re-examined. After that the plaintiff or his advocate sums up the case by making a closing speech. After that the Defendant states their case and makes a closing speech. Procedure 2 – Defence elects to call evidence Advocates for the plaintiff makes an opening statement, the plaintiff witnesses are called, examined, cross-examined and re-examined. After that the defendant’s counsel makes an opening statement. After that the defendant’s witnesses are called, examined, cross examined and re examined. After the Plaintiff or his advocate sums up the case by making the closing speech. Thereafter the defendant sums up the case and makes a closing speech also. The Defendant can reply to the plaintiff’s closing. The reply only covers new ground. In cases where there are many defendants and many plaintiffs the same procedure will apply but if the defendants are represented separately, then the counsels will separately make their submissions separately by order of appearance. Cross examination of witness will also follow the order in which they proceed. Co plaintiffs will normally be represented by the same counsel. Who has the right to begin the case? Order XVII Rule 1 The plaintiff or the applicant has the right to begin. Of course there are certain exceptions to that right to begin. 1.Where the Defendant admits the facts alleged by the plaintiff but raises an objection on a part of law. In such a case the defendant should be entitled to begin by submitting on that part of the law. For example, suppose one raises a plea of Res Judicata? In such a case one can say that they have sued the defendant by they have raised an objection on the part of the law a and in this case, the Defendant has the right to begin on a plea of res judicata. Or the Defendant raises the plea of limitation, they have the right to submit on that point of law. However it is advisable that one should always put it in the pleadings whatever plea they intend to raise. 2.Where the Defendants admits the facts alleged by the plaintiff but states that the plaintiff is not entitled to the relief that they seek for example drawn from Seldon v. Davidson in which case the plaintiff brought proceedings for recovery of a debt. In their defence the defendants admitted that they received the money from the plaintiff but pleaded that the money was a gift. In this case the defendant has a right to begin. Suppose there are several issues? May be it could be many different parties and there is a dispute as to who should have the right to begin? The court will direct that the party with the burden of proving the majority of issues shall begin. OPENING STATEMENT What should it contain It is usually a brief outline of either the defendant’s or the plaintiff’s case, usually it will state the facts simply. They will be telling the court the witness that they intend to call and will be giving a preview of what they intend to prove. Usually this is an introduction to the entire trial and it is important that it is interesting, logical, believable and in a narrative form. Usually it is not necessary for the Judge to record the opening speeches unless one raises a point of law. It is important that a note should be made in the court record that an opening speech was made. an opening speech must not contain evidence. It should just be limited to a statement of basic facts that the parties intend to prove or rely on as defence. After you make the opening statements, you move on to examination in chief. EXAMINATION OF WITNESSES Examination in Chief When you call a witness there are 3 stages 1.Examination in chief 2.Cross Examination 3.Re examination Examination in Chief The object of examination in chief is to elicit facts that are favourable to the case of the party calling the witness. In other words the exam in chief is when you question your first witness. Sometimes the plaintiffs themselves. Normally they will be giving evidence that will be favourable to their case. It is governed by two rules (a)The witness cannot be asked leading questions – these are questions that suggest the answer expected of that person. For example you cannot ask Was your business running into financial difficulties last year? You should ask what was the financial position of your business last year? The art of knowing whether a question is leading is learnt with experience. (b)The examination must not be conducted in an attacking manner. Usually at cross examination you can attack but you cannot do that to your own witness. If your witness turns hostile, you can ask the court to declare the witness a hostile witness and once the court does that, you can then at tack the witness. When a witness is declared hostile (i)You will be allowed to impeach the creditability of that witness; (ii)You can ask leading questions (iii)You can ask them questions that touch on their truthfulness and even their past character and previous convictions. (iv)You can also be able to examine on certain issues by leave of the judge e.g. you can question the hostile witness on statements they made previously which is inconsistent with their present testimony. This can help to show that the witne3ss is giving conflicting evidence which the court is allowed to resolve when they are taking the evidence into account. You must take witness statements. If they give evidence inconsistent with the statement that they signed, you can impeach their credibility and produce the witness statement. CROSS EXAMINATION There are 3 aims of cross examination 1.To elicit further facts which are favourable to the cross examining party; 2.To test and if possible cast doubt on the evidence given by the witness in chief; 3.To impeach the credibility of the witness. Cross examination – the scope is wide one is allowed to ask leading questions, question a witness on previous testimony, it is not restricted in any way. A good Advocate will never forget the virtue of courtesy. RE EXAMINATION Once you have examined your witness in chief, the other side cross-examines your witness. The re examination is a kind of retrieval process. This is when you try to heal the wounds that were opened up in cross examination. Most important, re-examination is strictly restricted to matters that arose at cross examination. The court also has powers to ask a witness questions for the purpose of clarifying points. SUBMISSION OF NO CASE TO ANSWER The defendant may make a defence of no case to answer after the submission by the plaintiff. The Judge must decide whether there is any evidence that would justify putting the defendants on their defence. Usually if the submission of no case to answer is not upheld, the case continues. If the court says that there is no case to answer, that ruling can be challenged on Appeal. TAKING DOWN EVIDENCE Usually evidence of witnesses is taken orally in open court under the direction of a Magistrate or Judge, it is normally written down in narrative form i.e. not question and answer form but where there is special reason, the evidence may be in question and answer form. The rule is that the court may on its motion taken down a particular question verbatim and the answer verbatim. Where either party objects to a question and the court allows it, then the court should record the question, the answer and the objection and the name of the person raising the objection and if they make a ruling they must also record the ruling of the objection raised. Tact is required as you may find that. Sometimes if you object too much you can irritate the Judge. Object only for important things. In the course of taking evidence, the court may also record remarks made by witnesses while under examination and normally after taking down the evidence the judge will sign that evidence. The courts can also record remarks and demeanour of a witness. PROSECUTION & ADJOURNMENT OF SUITS Public policy documents that business of the court should be conducted expeditiously. It is of great importance and in the interest of justice that action should be brought to trial and finalised with minimum delay. Order XVI Rule 1 requires that hearing of cases should be on a day to day basis until all witnesses have testified. However this is not always possible and that is why the court may adjourn a hearing on its own motion or upon application by either of the parties where good course is shown. The rule requires that adjournments can be granted where good cause is shown Habib V Rajput the plaintiff case came up for hearing, the advocates applied for adjournment on the grounds that their client was absent for some unexplained reasons. The respondent opposed saying that his witnesses were already in court and had come from very far away and it was costing a few thousand shillings to keep them there per day. Was the plaintiff’s reason good cause to adjourn. The court ruled that no sufficient cause was shown and the application for adjournment was dismissed. Kamil V. Merali NO STEPS TAKEN – Order XVI Rule 6 Under Rule 6, where no application has been made or steps taken for 3 years by either party, the court may order the suit to be dismissed but usually the application should show cause why the suit should not be dismissed. Any case which is dismissed under Rule 6 can be instituted afresh subject to rules of limitation. Victoria Construction Co. V. Dugall The court considered the meaning of steps taken within the meaning of Rule 6. the Case was filed in November 1958 and in 1960 the Applicant decided to refer the case to an arbitrator but attempts to resolve the dispute through arbitration failed. The matter went to sleep until 1962 where the registrar asked the parties to show cause why the suit should not be dismissed. The Plaintiff contended that the steps to seek arbitration amounted to steps taken. The question was whether an agreement to refer the matter to arbitration was a step taken and the court held that that was not a step taken and the case was dismissed. In this case, the court explained 1.That one has to satisfy the court that the suit is ready to proceed without delay. 2.One has to satisfy the court that the defendant will suffer no hardship; 3.That there has been none frequent inactivity by the Plaintiff. It is advisable at the time the case comes up for hearing to ask that it be stood over generally (SOG) to give you time to go to arbitration and if you are not ready, you can always go back to court and seek an extension. This way there is a step taken. CLOSING SPEECH You are telling the court that you have presented your evidence, that you have proved that so and so is liable and you will also be telling the court that this is the law and if applied to the facts of your case then the law should support your prayers. You will be telling the court of past decisions that support your case. You will reconcile the facts, the law and past decisions that support your case. You make your case in the closing statements.

Studies suggest that culturally-influenced concepts of gender role Essay

Studies suggest that culturally-influenced concepts of gender role norms are associated with health - Essay Example ever, argue that women can become economically empowered through microfinance initiatives and be able to realize improvements in self-confidence and esteem, solve household conflicts as well as participating in decision making (p. 1795). Conversely, through their IMAGE study, the researchers argue that microfinance interventions empowers women economically and helps to reduce sexual IPV or physical violence by enabling them to challenge gender violence, demand better treatment, leave violent relationships, mobilize community groupings to denounce gender-based violence, in addition to, addressing the problem of HIV/AIDS infections (P. 1798). On the other hand, Pulerwitz et al. (2015) argues that, â€Å"Certain gender norms—or social expectations about men’s and women’s appropriate roles, rights, and responsibilities—have been shown to be associated with the risk of IPV as well as the risk of HIV and other sexually transmitted infections (STIs)† (p. 132). However, through interventions aimed at addressing inequitable gender norms, reductions in violence and positive health outcomes can be realized (P. 132). This can be realized by incorporating boys and men in initiatives aimed at shunning inequitable gender norms by changing their attitudes and beliefs, as well as the need for inclusive household decision-making (p. 135). The emic knowledge is predominant in cultural setups and is guided by the people`s beliefs, meaning and is determined by the local customs or norms. In the African American society, there exist MSN, who are men who have sex with other men. The emic approach can help in carrying out an investigation into the cultural factors contributing to MSN that has led to the widespread of HIV/AIDS among African American men. Taking an insider’s perspective, it is possible to understand gender norms and be able to distinguish appropriate gender roles, responsibilities and rights for each sex (Pulerwitz et al., 2015). Thus, using the emic approach the

ACCOUNTING THEORY Essay Example | Topics and Well Written Essays - 2000 words

ACCOUNTING THEORY - Essay Example Among these are the ground concepts that may be used in the formulation of accounting theories among other aspects of accounting theories. Some contend that in the beginning many primitive societies, those that were in existent in the earliest days, developed the art of counting before developing the art of naming (Brown, 2006, 3). These primitive forms of accounting for the number of items provide the basis by which early societies may be said to have been practicing accounting. Such groups are likes of the Egyptian with the need to account for grain harvested and stored. Examples of other such systems may be found in other early civilizations such as the Greeks and the Tibetans. Over time these systems of accounting for various items moved into the business world. This was in earlier European and Asian countries that mostly participated in trade with one another and within their countries. One will find evidence of the differences in practices among the various countries to indicat e differentiation in as far as the earlier practice of accounting is concerned. There is also need to mention the contribution of the likes of Luca Pacioli who made contributions to the earlier forms of accounting (Riahi-Belkaoui, 2005, 3). He is credited with developing the double entry system of bookkeeping that is still widely taught and practiced in accounting spheres to date. It is though that over time this Italian system of accounting was adopted in most parts of the world. In the United States various forms of accounting methodologies were also being applied. These methods may not have been allowed for uniformity, due to the differences in the underlying guidelines. These theories were to be streamlined with the development of bodies such as the SEC which became the ultimate authority as far as providing guidance on accounting related matters (Previtis, Walton & Wolnizer, 2011, 121). Accounting theory development The development of accounting theory on the other hand may be said to have progressed with the developments that were being experienced in the accounting field. Their development was also being fueled by the changes that were occurring in corporate world. A good example may be the case with the development of the railway that led to the growth of the stock market for the purposes of raising needed financing. This growth in a whole industry catapulted the need to develop theories to be used in corporate financing deals (Schroeder, Clark & Cathey, 2011, 4). The current environment The recent financial crisis affected the world in a way that most did not see coming. This crisis also exposed a lot of the misdeeds that have been happening in the financial world. The effect is that there has been an increase in the oversight that is being paid to these sectors of the economy. Accountants and the accounting theories that they choose to use are being placed under greater scrutiny by various bodies. This is in a bid to try and prevent the recurrence of another crisis. The major concern being caused by the derivatives that have come to play a major part in corporate entities and that may have carried some blame when it comes to the causal effect of the crisis. Accounting for these derivatives requires additional accounting regulations as compared to other marketable securities (Stickney, 2010, 579). Accounting theory definition Before an in depth analysis and look at the various theories and how they affect the accounting world, one needs to be aware of the definition or the basic characteristics of an accounting theory. Dictionaries place the definition as, well organized knowledge that can be applied in a wide variety of situations. These are principles and assumptions that can be used to predict how a given

Clinical Pharmacy - Essay Example It is evident that besides balanced food that is given to the patient some other nutrient supplements facilitate in recovery and reduce the health related troubles that become devastating if deficiency is related with the nutrients required for the well being. Patients are getting variety and choice of nutrition feed because of the commercial availability of many products in the market. Many companies are coming up with a special protocol of feed and related illness. This enhances the awareness of patient about the kind of food essential to combat illness (Concern at nutrition in hospitals). Nutrition supplements are licensed products and can be provided as the sole source of nutrition. They may be prescribed on medical grounds for diverse ailments. Depending on the severity and class of sickness, the nutrition supplements can be taken. Hospitals play lead role in making the patient aware of the consequences if the nutrition is not provided in the desired quantity. Hospital staff must help the patient psychologically, the advantages and disadvantages of the feed type he has been introduced to. This not only prepares the patient mentally but patient also co-operates with the hospital staff. Keeping this in mind the present study is conducted to build an understanding towards the nutritional support products, their advantages and problems and the available products that patient can utilize for better and sooner recovery. Basically three types of feeds are given for diverse ailments these are: Sip feeds, Enteral (tube) feeds and TPN feeds. Sip Feeds Various policies are defined to prescribe Sip feeds or Oral Nutrition Supplements for Patients with poor nutritional status especially those having: Disease related malnutritione.g. Reduced appetite or experience difficulty in swallowing, in cancer of throat or gut. Short-bowel syndrome (SBS) Intractable malapsorption Pre-operative preparation of undernourished patients Proven inflammatory bowel disease Following total gastrectomy Dysphagia Bowel Fistulas CAP Dialysis (Nutrition support in adults) Importance of Sip feed: Help the patient to gain weight or avoid loss of weight. Help the patient to surmount weakness of tiredness Help the patient to take in adequate liquid. Help the patient to alleviate the pressure to eat Help the patient to drink enough when dietary supplements cannot. (Nutrition support in adults) Before prescribing Sip feed it is essential to assess nutritional status, BMI calculation and weight loss by using simple nutritional risk scoring system When prescribing sip feeds * Do try equipped standard food (by adding milk, butter, cheese or cream)as first line therapy (4weeks before stipulating sip feeds). * Ensure that all patients be given suitable dietary advice by a state-registered dietitian or suitable trained member of the primary health care team. * No long term use without regular monitoring and assessment * It should not exceed 500-600kcals daily unless under the care of a dietitian. * Ensure that supplements are not taken at meal times / after meals e.g. as a bedtime drink to avoid reduction in food intake. * It should not be given as the sole source of nutrition except in consultation with
