Coping with Short-term Sustained Peak Demands ,several cost-effective strategies

For most open universities, in fact for most universities, there will arise occasions when some online activities will have to be completed by all students in a very short time interval. These occasions usually result in a great rush to get online as quickly as possible ; the rush is often made worst by the limited good choices on offer such that usually only the earliest can get the best. Choosing and confirming elective subjects, when only a limited number for each are offered, on a first-come-first-served basis is an example. At the Open University Malaysia the rush occurs when confirming offered subjects and choosing face-to-face meeting timetable. Most students rushed to be earliest to ensure choice slots in the timetable are obtained. Available I. T. resources such as Internet bandwidth and servers cannot cope with these short-term sustained peak demands. Unless these peak demands are met, however, online services will slow down drastically resulting in long queues of users waiting to be served. Providing excess capacity, if at all possible, to ensure these short duration peak demands can be met would not be cost-effective since most of the time these resources are not utilised. This paper will look at some cost-effective approaches to meeting these short-term peak demands.     

The Role that φ-Features Play in Long Distance Binding

.INTRODUCTIONThis article attempts to investigate long distance binding in Chinese under a feature- orientated ap-proach based on the studies done by Battistella ( 1 989) ,Tang ( 1 986) ,Cole and Sung ( 1 990 ) and oth-ers.The data presented in this article demonstrated,contrary to the prevailing assumption that- fea-tures of reflexives in various language are base generated,long distance reflexives before movement atL F have barren or impoverishedφ- features.On this basis,itis demonstrated thata reflexive ...

The effectiveness of farm programmes on Bangladesh Betar in educating farmers

Farm programmes (FPs) of varied categories have been developed and aired over several decades by Bangladesh Betar, the national radio of Bangladesh for the diffusion of farm technologies. The study aimed to produce an in-depth academic evaluation of their effectiveness in educating farmers in Bangladesh. A sample of 465 respondents from the Khulna and Rajshahi divisions in Bangladesh was randomly selected for a questionnaire survey. To analyse the data, relevant documents were collected from the Ministry of Information, the Ministry of Agriculture, and the Ministry of Fisheries and Livestock of Bangladesh. Frequency distribution, z-test, and binary logistic regression analysis were used as statistical tools. The farm knowledge levels of the farmers were considered the predictors for evaluating the effectiveness of FPs. The results revealed that 93.33% of the sample did not listen to the FPs, while only very few of the listeners listened regularly. Despite this, at the ‘weak’ and ‘average’ levels of knowledge significant differences were noted between listener and non-listener farmers of FPs. The binary logistic regression analysis (Model 1) identified that the farmers who listened to the FPs were likely to acquire farm knowledge 6.62 times more than the farmers who did not listen to the FPs. The farmers who listened to the FPs were likely to have farm knowledge 2.64 times more than the farmers who did not listen to the FPs but consulted with other sources of farming information (Model 2). Similarly, a listener of FPs with farm training was likely to acquire farm knowledge 5.76 times more than a non-listener with farm training (Model 3). The FPs were found to be very effective and could be used to better complement other mechanisms for educating farmers. Regular access to the FPs ought to be ensured through appropriate stimulants for the diffusion of farm technologies.
