Business research paper - Essay Example As part of the inquisition the research will make use of timestamps such as Weblog and news articles to feed as input materials to generate results that will be presented graphical. The graphical details will highlight major sentiments like anxiety, despair and disappointment. In addition, the development that comes with each of sentiments will be presented to illustrate for instance how the earthquake news was received and the corresponding reactions that followed afterwards. Essentially, the main motivation for using this method is for convenience since the participant dependent and independent variables are within meaningful reach. There are a good number of published as well as unpublished literature on the subject of sentiment analysis in both the academic and policy circles. Incidentally, in this review the most astounding works that have significant bearings on the subject matter will be reviewed. To begin with, it is undoubtedly prudent to establish the internal dynamics of sentimentalism. The paper benefits from the earlier work of pioneers who discovered the so-called semantic orientation of examination of a statement or a written material (Turney, 2002). Also according to Pang et la (2002), a sentence can be assessed to identify the positive and negative elements contained in it. Unlike the above mentioned works, this work will be influenced by the system of multi-polar analysis in order to draw the clear distinction between this and other previous papers. In a related context, researchers Mishne and de Rijke (2006) have advocated for a system that can evaluate momentary changes in the moods of people, it is what they term "Moodviews." Fundamentally, the analysis is carried out with the aid of over one hundred sentiments. A good number of scholarly works have been carried out on the question of "topic detection and tracking" with each of these groups making their own proposals depending on what is deemed fit for each circumstances. Interestingly, there is a gross limitation of work that fully addresses the utilization of sentiments under the "topic detection and tracking" column and this is precisely what this paper will be addressing. The process will also incorporate what Havre et al (2002), called information visualization. Research Results At the end of the research the following outcomes represented below are expected to be generated. A graph will be plotted to highlight the sentiments generated especially in the wake of the turbulent earthquake that occurred a little while before the official opening of the 2008 International Olympic Games hosted in Beijing, China. The X-axis of the graph will capture the dates where as the resultant sentiments will be presented on the Y-axis. The main sentiments expressed here are shock, anxiety and despair. Conclusion The research will deal with analyzing momentary trends in sentiments generated from the pre-Olympics euphoria as well as the aftermath. Qualitative and quantitative

The importance of banqueting and what type of events there are and how Essay - 1

The importance of banqueting and what type of events there are and how banqueting fits in - Essay Example Many guests introduce each other during a banquet and thus one can consider banqueting as a social event. Here you meet new people and make friends. Even the marketers, now days, use banqueting to promote and advertise their products. Many marketers even hold lucky draws and other brand activities during a banquet and all of this signifies the great importance that banqueting holds for people of our generation. A special event is a one-time event and does not recur on a continuing basis. This makes it unique and it basically held for the purpose of ground breaking, grand opening or other significant moments in life. Concerts and job fairs are also considered as special programme because they cannot be repeated or reproduced. Since, special events are one-time events, special management techniques are required to make these events a success. Many people suffer from improper management of these events which kills the purpose of these events. Therefore, planning these events is the key. You need to make sure that you have the resources and manpower to arrange and successfully host the event. A good starting point in the event management is developing a check list of the resources that you need. A written checklist is important because it can be referred to in the future and important details are not forgotten. Once the event is successfully stage, you need to take some time after the event to evaluate the significance of the event, that is how well it was hosted and stage. For this, a written document is better because you can write down the details while still fresh, reducing the chances that you forget your mistake and they might reoccur again. These steps make events unique and fulfill the purpose of ho lding special events. Banqueting fits in any event as a closing gesture, and signifies the end of an event. The food that is to be

Foundation Certification – My Short Notes Essay A team or group of people and the tools they use to carry out one or more processes or activities. Functions provide units of organization responsible for specific outcomes. Functions are logically isolated from each other. Definition – Process A set of coordinated activities combining and implementing resources and capabilities in order to produce an outcome and provide value to customers or stakeholders. Process has following attributes. Trigger, Activity, Dependency Sequence Process should be measurable Process should produce specific output Process should meet customer expectation Definition – Process Owner The person/role responsible for ensuring that the process is fit for the desired purpose and is accountable for the outputs of that process. Definition – Service Owner The person/role accountable for the delivery of a specific IT Service. They are responsible for continual improvement and management of change affecting services under their care. The service owner is a primary stakeholder in all of the underlying IT processes that enable or support the service they own. Definition – Service A means of delivering value to customers by facilitating outcomes customers want to achieve without the ownership of specific costs or risks. Definition – RACI Model R – Responsibility (at least 1R per activity who is doing the actual work) A – Accountability (1 A per activity) C – Consult I – Inform Service Strategy The purpose is to define the perspective, position, plans, and patterns that a service provider needs to be able to execute to meet an organization’s business outcomes * Perspective – Defines the organization’s view of itself, generally communicated through the organization’s vision and direction. * Positions – Defines the distinctiveness of the organization in comparison to its competitive market and as identified through the minds of its customers. * Plans – The predefined details for supporting and enhancing the organization’s perspective and positions, usually identifying a potential future state for the organization and a strategic response to the state and level of investment required. * Patterns – Defines the conditions and actions that must be consistently in place and repeatable to achieve the objectives of the organization; patterns allow the organization to predict the future. Service strategy defines the role of serv ices and service provider in achieving the business objectives of the organization through management of IT. Value to Customer To enable a service provider to create value for a customer, a systematic approach has to be adopted. For ITIL, this approach is determining service utility and service warranty. Service Warranty (Fit for use) + Service Utility (Fit for propose) = Service Value Service utility and service warranty are present for every service provided to a customer. One cannot exist without the other. By describing both Service Utility and Service Warranty, it enables the provider to clearly establish the value of the service, differentiate themselves from the competition, and, when necessary, attach a meaningful price tag that has relevance to the customer and associated market space. Service Package = Enabling Services + Core Services + Enhancing Services Definition – Service Asset A Service Asset is any resource or capability used in the provision of services Definition – Business Case The business case is a detailed analysis of the benefits and impact of the business action in meeting the business objective and disrupting the delivery of other IT services.

Cache Memory: Definition and Function

Cache Memory: Definition and Function CACHE MEMORY Cache memory is random access memory (RAM) that a pc micro chip will access a lot of quickly than it will access regular RAM. because the micro chip processes knowledge, its initial within the cache memory and if it finds the information there (from a previous reading of data), it doesnt got to do the a lot of long reading of knowledge from larger memory. Cache memory is usually delineate in levels of closeness and accessibility to the micro chip. associate L1 cache is on identical chip because the micro chip. L2 is typically a separate static RAM (SRAM) chip. the most RAM is typically a dynamic RAM (DRAM) chip. In addition to cache memory, one will think about RAM itself as a cache of memory for disc storage since all of RAMs contents return from the disc at the start. once the processor has to scan from or write to a location in main memory, it initial checks whether or not a duplicate of that knowledge is within the cache. If so, the processor straightaway reads from or writes to the cache, that is far quicker than reading from or writing to main memory. a translation look aside buffer (TLB) wont to speed up virtual-to-physical address translation for each practicable directions and knowledge. Knowledge is transferred between memory and cache in blocks of mounted size, known as cache lines. once a cache line is derived from memory into the cache, a cache entry is made. The cache entry can embody the derived knowledge in addition because the requested memory location currently known as a tag. once the processor has to scan or write a location in main memory, it initial checks for a corresponding entry within the cache. The cache checks for the contents of the requested memory location in any cache lines that may contain that address. If the processor finds that the memory location is within the cache, a cache hit has occurred. WRITE POLICY: If knowledge is written to the cache, at some purpose it should even be written to main memory. A write policy determines however the cache deals with a write cycle. The 2 common write  policies area unit Write-Back and Write-Through. WRITE BACK POLICY In Write-Back policy, the cache acts sort of a buffer. That is, once the processor starts a write cycle the cache receives the information and terminates the cycle. The cache then writes the information back to main memory once the system bus is offered. This technique provides the best  performance by permitting the processor to continue its tasks whereas main memory is updated at a  later time. However, dominant writes to main memory increase the cache’s quality and  cost. WRITE THROUGH POLICY The second technique is that the Write-Through policy. because the name implies, the processor writes through the cache to main memory. The cache could update its contents, but the write cycle doesnt finish till the information is keep into main memory. This technique is a smaller amount advanced. The primary drawback with write-through caches is their higher write traffic as compared to write-back caches. a method to scale back this traffic is to use a coalescing write buffer, wherever writes to addresses already within the write buffer area unit combined. once a write misses within the write cache, the LRU entry is transferred to the write buffer to create area for the present write. In actual implementation, the write cache may be integrated with a coalescing write buffer. Write through policy is most prefererable in memory application than write back policy as a result of it embody the property of automatic update once any changes occur in cache block itll replicate into main memory. CONVENTIONAL 2 LEVEL CACHE Fig. 3illustrates the design of the two-level cache. solely the L1 knowledge cache and L2 unified cache area unit shown because the L1 instruction cache solely reads from the L2 cache. below the write through policy, the L2 cache continuously maintains the foremost recent copy of the information. Thus, whenever a knowledge is updated within the L1 cache, the L2 cache is updated with identical knowledge in addition. This ends up in a rise within the write accesses to the L2 cache and consequently a lot of energy consumption. The locations (i. e. , approach tags) of L1 knowledge copies within the L2 cache wont modification till the information area unit evicted from the L2 cache. The planned way-tagged cache exploits this reality to scale back the quantity of the way accessed throughout L2 cache accesses. once the L1 knowledge cache masses a knowledge from the L2 cache, the approach tag of the information within the L2 cache is additionally sent  to the L1 cache and keep during a new set of approach-tag arrays These way tags give the key data for the following write accesses to the L2 cache. In general, each write and browse accesses within the L1 cache may have to access the L2 cache. These accesses result in totally different operations within the planned way-tagged cache, as summarized in Table I. below the write-through policy, all write operations of the L1 cache got to access the L2 cache. within the case of a write hit within the L1 cache, only 1 approach within the L2 cache are going to be activated as a result of the approach tag data of the L2 cache is offered, i. e. , from the approach-tag arrays we are able to acquire the L2 way of the accessed knowledge. whereas for a write miss within the L1 cache, the requested knowledge isnt keep within the L1 cache. As a result, its corresponding L2 approach data isnt offered within the way-tag arrays. Therefore, all ways that within the L2 cache got to be activated at the same time. Since write hit/miss isnt proverbial a priori, the way-tag arrays got to be accessed at the same time with all L1 write operations so as to avoid performance degradation. Note that the way-tag arrays area unit terribly little and also the concerned energy overhead may be simply salaried for (see section). For L1 scan operations, neither scan hits nor misses got to access the way-tag arrays. this is often as a result of scan hits dont got to access the L2 cache; whereas for scan misses, the corresponding approach tag data isnt offered within the way-tag arrays. As a result, all ways that within the L2 cache area unit activated at the same time below scan misses. PROPOSED approach TAG CACHE we tend to introduce many new components: way-tag arrays, way-tag buffer, approach decoder, and approach register, all shown within the line. The approach tags of every cache line within the L2 cache area unit maintained within the way-tag arrays, set with the L1 knowledge cache. Note that write buffers area unit normally used in write through caches (and even in several write-back caches) to boost the performance. With a write buffer, the information to be written into the L1 cache is additionally sent to the write buffer. The operations keep within the write buffer area unit then sent to the L2 cache in sequence. This avoids write stalls once the processor waits for write operations to be completed within the L2 cache. within the planned technique, we tend to conjointly got to send the approach tags keep within the way-tag arrays to the L2 cache at the side of the operations within the write buffer. Thus, alittle approach-tag buffer is introduced to buffer the way tags scan from th e way-tag arrays. {a approach|how|some way|the way|the simplest way} rewriter is used to decode way tags and generate the alter signals for the L2 cache, that activate solely the specified ways that within the L2 cache. every approach within the L2 cache is encoded into the simplest way tag. {a approach|how|some way|the way|the simplest way} register stores way tags and provides this data to the way-tag arrays. IMPLEMENTATION OF WAY-TAGGED CACHE WAY-TAG ARRAYS Way tag arrays have approach tags of a knowledge is loaded from the L2 cache to the L1 cache, shown in Fig three. Note that {the knowledge|the info|the information} arrays within the L1 data cache and also the way-tag arrays share identical address from hardware. The WRITEH_W signal of way-tag arrays is generated from the write/read signal of {the knowledge|the info|the information} arrays within the L1 data cache as shown in Fig. 8. A UPDATE is management signal, obtained from the cache controller. once a L1 write miss, UPDATE are going to be declared and permit WRITEH_W to alter the write operation to the way-tag arrays (UPDATE=1 and WRITEH_W, See Table II). UPDATE keeps invalid and WRITEH_W =1, a scan operation to the way-tag arrays. During the scan operations of the L1 cache, the way-tag arrays dont got to be accessed and so, scale back energy overhead. to attenuate the overhead of approach tag arrays, the scale of a way-tag array may be expressed as Where SL1, Sline,L1 and Nway,L1 area unit the scale of the L1 knowledge cache, cache line size and variety of the ways that within the L1data cache severally. Bway,L2= may be a code. The way-tag arrays area unit operated in parallel with the L1 knowledge cache for avoiding the performance degradation. as a result of their little size, the access delay is far smaller than that of the L1 cache. WAY-TAG BUFFER Way-tag buffer is quickly stores the approach tags from the way-tag arrays within the L1 cache. its identical variety of entries because the write buffer of the L2 cache and shares the management signals with it. Note that write buffers area unit normally used, the information to be written into the L1 cache is additionally sent to the write buffer to boost the performance. This avoids write stalls once the processor waits for write operations to be completed within the L2 cache. When a write miss happens in L1 cache, all the ways that within the L2 cache got to be activated because the approach data isnt offered. Otherwise, solely the specified approach is activated. approach tag buffer is little in to avoid space overhead. Approach DECODER The operate of the approach rewriter is used to decode approach tags and generate the alter signal, that activate solely desired ways that in L2 cache. This avoids the extra wires and also the chip space is negligible. A write hit within the L1 cache, the approach decoder works as associate n -to- N decoder that selects one way-enable signal. For a write miss or a scan miss within the L1 cache, the approach decoder assert all way-enable signals, in order that all ways that within the L2 cache area unit activated. Approach REGISTER The approach tags for the way-tag arrays is Provided by approach register. A 4-way L2 cache is take into account, that labels â€Å"00†, â€Å"01†, â€Å"10†, andâ€Å"11†. This area unit keep within the approach register. once the L1 cache masses a knowledge from the L2 cache, the corresponding approach tag within the approach register is distributed to the approach-tag arrays by this way the corresponding way tags area unit keep in way-tag array. The planned approach-tagged caches way operates below totally different modes throughout scan and write operations. solely the approach containing the specified knowledge is activated within the L2 cache for a write hit within the L1 cache, operating the L2 cache equivalently a direct-mapping cache to scale back energy consumption while not performance overhead below the write-through policy. APPLICATION OF approach TAGGING IN PHASED ACCESS CACHES In this section, we are going to show that the thought of approach tagging may be extended to alternative low-power cache style techniques suchas the phased access cache [18]. Note that since the processor performance is a smaller amount sensitive to the latency of L2 caches, several processors use phased accesses of tag and knowledge arrays in L2 caches to scale back energy consumption. By applying the thought of approach tagging, any energy reduction may be achieved while not introducing performance degradation. In phased caches, all {ways|ways that|ways in that} within the cache tag arrays got to be activated to work out which approach within the knowledge arrays contains the specified knowledge (as shown within the solid-line a part of Fig. 8). within the past, the energy consumption of cache tag arrays has been unnoticed as a result of their comparatively little sizes As superior microprocessors begin to utilize longer addresses, cache tag arrays become larger. Also, high associativity is vital for L2 caches in bound applications. These factors result in the upper energy consumption in accessing cache tag arrays. Therefore, its become vital to scale back the energy consumption of cache tag arrays. the thought of approach tagging may be applied to the tag arrays of phased access cache used as a L2 cache. Note that the tag arrays dont got to be accessed for a write hit within the L1 cache (as shown within the dotted-line half in Fig. 9). {this is|this is often|this may be} as a result of the destination approach of knowledge arrays can be determined directly from the output of the approach decoder shown in Fig. 7. Thus, by accessing fewer ways that within the cache tag arrays, the energy consumption of phased access caches may be any reduced The operation of this cache is summarized in Fig. 9. Multiplexor M1 is used to get the alter signal for the tag arrays of the L2 cache. once the standing bit within the way-tag buffer indicates a write hit, M1 outputs â€Å"0† to disable all the ways that within the tag arrays. As mentioned before, the destination approach of the access may be obtained from the approach decoder and so no tag comparison is required during this case. Multiplexor money supply chooses the output from the approach decoder because the choice signal for the information arrays. If on the opposite hand the access is caused by a write miss or a scan miss from the L1 cache, all ways that area unit enabled by the tag array decoder, and also the results of tag comparison is chosen by money supply because the choice signal for the information arrays. Overall, fewer ways that within the tag arrays area unit activated, thereby reducing the energy consumption of the phased access cache. Note that the phased ac cess cache divides associate access into 2 phases; so, money supply isnt on the crucial path. Applying approach tagging doesnt introduce performance overhead as compared with the standard phased cache. Common or Shared LUT design A shared or common LUT design is planned to be applied in knowledge array management of this cache design. Since knowledge array in cache design is related to electronic device choice based mostly processor for knowledge accessing, we tend to area unit introducing associate shared LUT during which all knowledge data is loaded with table loader per is index and coefficients for knowledge finding and matching allocation throughout cache operations. thus knowledge array may be replaced by shared LUT design with effectively acts and reduces the whole power consumption of overall approach tag array cache design. From the fig. 7. the shared LUT design is divided in to four banks with several address related to it. If a processor has to access knowledge from bank three, itll directly access that data via its constant bit address by matching with table loader indexes. Hence a protracted looking method is proscribed to direct accessing technique through shared LUT design. Apart from banks it conjointly has SFU-Special practical Units in it. its connected to table loader. These SFU’s will access all the banks by having easy indexes like â€Å"000† the primary zero represents the quantity of SFU i. e SFU 0. thus the remainder 2 zero’s represents the bank constant. By bit matching, SFU simply connects with bank zero that contain relevant knowledge access in cache operations. If SFU0 and SFU one having values like â€Å"000† and â€Å"100† then confusion is cleared by higher priority portal. the upper priority is nothing however one that comes initial is allowed to access the information initial too. the remainder request signals accessed in  Ã‚  parallel at that time.

Alternative Dispute Resolution   Ã‚  Ã‚  Ã‚  Ã‚  Alternative Dispute Resolution is the most important aspect in the court’s structure because it allows to resolve disputes before ever having to spend money or time. Having to use the court system to resolve disputes can take several years and cost a lot of money. Companies have taken into their system ADR because it can solve problems faster and cost less money. Every company can sure have ADR in every single case they have because they can save tons of money and time.   Ã‚  Ã‚  Ã‚  Ã‚   Not always disputes can be solved, this means that people have to take that extra mile to solve the dispute. If the parties do not agree with the decision taken by the arbitrator it can be appealed. The Congress made an act, the Federal Arbitration Act, they promote the dispute for the courts at the state level. The Uniform Arbitration Act is that people before been send to court they have to go through other ADR. There are many forms of ADR: arbitration, meditation, conciliation, minitrial, fact-fading and judicial referee. In ADR you use the most common form that is arbitration. This form is where the parties involved choose and impartial third person to listen and decide who should win the dispute. This third person is chosen by the American Arbitration Association. The courts that address this issues depend on what the arbitrator says. The court tend to have great deference with the arbitrator. There are many cases that get solved with ADR but some do not. There is something that comes into my mind every time I hear ADR, it is that you can save money and time when you use arbitrators. Personally I have been there and it does really save time and money. I had a case between X and myself. In this case I was arguing because my car’s transmission broke down and my car was still in warranty and because of some engine alterations they void my warranty. When I was told that my warranty was voided I went to DACO and they told me that they were going to help me get my car fixed with warranty. I think to myself that thanks to DACO I did not had to pay one thousand pure american dollars. DACO in my case worked as and arbitrator and help me get my problem solved in a couple of days and also made me save money.

Differences and Similarities of Short Stories :: The Withered Arm The Red Room Essays

Differences and Similarities of Short Stories In this essay I will be comparing the differences and similarities of four short stories I have read, , 'The Signalman', The Red Room', 'The Man with the Twisted Lip' and 'The Withered Arm' also I will be looking at how the writers have created an atmosphere. The four stories are all of mystery and try to keep the reader gripped until the end, all have areas in which there is suspense. In 'The Signalman' Charles Dickens keeps the reader in suspense because when the ghost visits the signal man you don't really know who the haunting warning is for. In 'The Red Room' H.G. Wells keeps the reader in suspense because when the ghost is sighted it is never really described. In 'The Man with the Twisted Lip' Arthur Conan Doyle keeps the reader in suspense by not actually telling if it is a murder on just disappearance. Also in 'The Withered Arm' Thomas Hardy keeps the reader in suspense because you find out who Gertrude catches the rash from. Each writer had a setting and different historical background 'The Signal Man' was written in 1866 by Charles Dickens, the surroundings for his story was an old railway station with old steam trains. The Man with the Twisted Lip' written by Sir Arthur Conan Doyle was written in 1860. This story was one of many Sherlock Holmes tales which display aspects of life in the last decade of Victorians reign. 'The Red Room' by H.G Wells was a Gothic horror story, which had traditional scenery at a castle (Loraine castle). 'The Red Room' was written in 1894, H.G Wells makes it obvious how ancient and old fashioned everything in the castle was. 'The Withered Arm' by Thomas Hardy was written in 1865 and located in Wessex, around Dorchester which Thomas Hardy calls Caster bridge the county town of Dorset where most of his stories were set. 'The Signalman' by Charles Dickens was set at an old rail way station, with steam trains. The idea of a signal box in the countryside and being manually operated, gives a sense of historical background for today's readers. 'The Man with the Twisted Lip' by Sir Arthur Conan Doyle was set in the streets of East London. A few years before the story was written a famous sequential killer 'Jack the Ripper' murdered people on the very same streets where the story was based on in the story it said "An endless succession of sombre and deserted streets. This gives the effect that the streets are frightening and vicious. 'The Red Room' by H.G Wells is a Gothic Horror story set in a

Trinidad Education

In Trinidad, The Ministry of Education has the policy of free education for all. They preach that this ‘free’ education is not based on class, wealth, race, gender or ethnicity but rather is a way to ensure that the entire nation is educated. Though these are the promises on Trinidad’s and Tobago’s Education Policy Paper, how is it that only nine of every one thousand people continue onto college, university or any higher education after secondary school? Twenty-one percent of Trinidadians live in poverty, which means that twenty-one percent of citizens do not have access to running water or proper health care. Because of this, many children in these poor families immediately enter the world of work or become ‘beggars’ to help feed their family. This shows the importance of social class on the initial decision of whether a child will be educated or not. This is not common as only two percent of Trinidad’s population is illiterate. I would categorize myself in the middle to high status class in my country and this has, in many ways affected my educational opportunities. I lived in a town known as Diego Martin and though my neighborhood mostly consisted of people within my same social class, the town itself has many neighborhoods consisting of people living in poverty. Pre-school education is not considered by government policies and therefore, there are no public pre-schools and if a family wants to enroll their child in preschool they would have to do so privately and with their own money. This goes to show that the first level of education in Trinidad is in fact not free. Because of this, my parents enrolled me in a private pre-school, which would indeed have to be paid for with their own money. This shows the immediate impact that class has on one’s education from just the first steps. Pre-school in Trinidad usually takes about two years and here is where a child learns his numbers and letters and therefore these children living under the poverty line are somewhat ‘robbed’ of these essential learning years. After this, a child must then be signed up for primary school where he or he will spend the following seven years. There are two hundred and sixteen primary schools in the country, one hundred and sixty-three of which are funded by various religious institutions, thirty-two of which are funded by the government and therefore are completely free of charge, and twenty-one of which are privately run. I attended a privately run school as these had higher success rates in the SEA or Secondary Entrance Assessment examination that all primary school students are prepared for in order to gain placement in the school of one’s choice. Once again, though there is an availability of free primary level education, the members of the middle and higher social class send their children to privately run schools in order to ensure that teachers are constantly present and not on strike due to low government wages, and that their children receive a more well-rounded education as there are funds now for sports and other recreational activities. Personally, attending a private school made me not only feel safe, as there were not usually guards present in government funded institutions due to high cost, but to also gave me the opportunities to join different sporting teams and go on school ‘outings’ to various national attractions and the necessary preparation to gain a placement in the secondary school of my choice- the number one girls secondary school in Trinidad. The entrance examination is one aspect that I can truly say that had absolutely nothing to do with class, race or ethnicity as each student was given an identification number and placement into choice schools was done based on results. These secondary schools were again a seven-year course. Therefore, in total one should spend sixteen years at school in order to complete what is considered a general education but the average number of years spent at school in Trinidad is eleven. This means that the average student ‘drops out’ of secondary school after two years. As a female in the top all girls’ institution, I became very gender bias as my school continuously obtained the most government scholarships year after year. Not only that, but nationally women received a significant number of scholarships more than the men did. This may have wrongly shaped my idea that women are in fact smarter than men based on what I experienced at home. Tertiary education for many Trinidadians is extremely class bias. There is one university known as the University of the West Indies and though it is extremely renowned in engineering and mathematical studies it can only facilitate a very small percentage of graduates every year. Therefore, if one wishes to study, he or she may have to look at schools abroad which is a huge expense for any family. Studying in the United States has been a great privilege for me that would never have been possible if I belonged to a lower social class. Overall, my social status granted me opportunities unimaginable for many residents in my country. Despite government efforts to better the education levels of the country there is still a lot to be done in order to meet the goal that class does not determine one’s level or education.
