Yield, growth and mortality rate of the Thai river sprat, Clupeichthys aesarnensis, in Sirinthorn Reservoir, Thailand

The Thai river sprat, Clupeichthys aesarnensis Wongratana, is a clupeid with a short life span, and supports artisanal fisheries in a number of reservoirs in the Mekong Basin. The growth parameters, mortality rates and the status of the Thai river sprat in Sirinthorn Reservoir (28 800 ha), NE Thailand (15°N; 105°E), are presented. The fishery is based on lured lift-nets, operated 7–14 days in the new moon period, September to April each year. It was shown that the von Bertalanffy growth function (VBGF) model was L_t (mm) = 78.43[1 − exp{−0.211[t − (−0.7996)]}] and its growth conformed to an isometric pattern. Natural mortality rate (month−¹) was 0.13 month−¹. Total mortality rates ranged from 0.69 to 1.53 month−¹ depending on the weather and the fishing season. Recruitment was continuous throughout the year but peaked in June and July. The yield per recruit model indicated that the exploitation rate of this fishery is probably too high.

Diminishing and negative welfare returns of economic growth : an index of sustainable economic welfare (ISEW) for Thailand

Thailand has achieved remarkable levels of economic growth over the last three decades. This sustained economic growth has played a major role in reducing absolute poverty levels from nearly one third of the population in 1975 to presently less than 10%, thus increasing the welfare of many Thais. This performance ranks Thailand as one of the world's most successful economies during this period. However, an increasing number of studies have begun to find that at a certain point achieving economic growth stops improving welfare and actually begins to diminish it due to the hidden and traditionally unreported costs of associated with this growth. With one exception, these new studies have focussed on high-income countries. This study will estimate an index of sustainable economic welfare (ISEW) for a developing country, Thailand, over a 25-year period, 1975–1999. This paper concludes that even low–middle income countries are beginning to approach the point in which economic growth produces both diminishing and, at times, negative welfare returns as the costs of achieving economic growth begin to outweigh the benefits. These results are important for policy makers and highlight the importance of implementing alternative welfare enhancing interventions that must be considered in place of simply achieving economic growth. The emphasis of this paper is not on the methodology of estimating the ISEW for Thailand, but rather on the policy implications for developing countries of diminishing and negative welfare returns brought about through the achievement of economic growth.

Achieving behaviour change: three generations of HIV/AIDS programming and jargon in Thailand

NGOs have played an important role worldwide in the fight to prevent the spread of HIV/AIDS through achieving behaviour change. NGOs have often been at the forefront of innovative changes, influencing government and international programming activities. This paper identifies and analyses the evolution of the HIV/AIDS programmes of one NGO in Thailand over a period of ten years. Three generations of programming are identified both through distinct approaches to this area of work and through the changing jargon used to describe the people the programmes are aimed at.

Measuring human well-being in Thailand : a normative social choice approach

Numerous methods exist within the literature to measure human well-being. A limitation of some approaches however is that they fail to explicitly consider society's views, choices and preferences on how human well-being should be defined. It is possible though to explicitly incorporate society's value judgements in defining and measuring human well-being through normative social choice theory. Normative social choice theory reflects the views, opinions and perspectives of societies of differing economic and social circumstances so that measures of human well-being retain their relevance for public policy makers in those countries. This paper reviews two indicators based on this theory for Thailand over the 25 year period, 1975-1999. The first indicator focuses on certain hierarchical needs and the second is a measure of adjusted national income. It is concluded that both measures provide important insights.

Widening development prescriptions: policy implications of an index of sustainable economic welfare (SEW) for Thailand

Over the past three decades, Thailand has recorded consistently high levels of economic growth, making it one of the most successful economies in the world during this period. However, economic growth has associated costs that can also reduce social welfare. This study will estimate an Index of Sustainable Economic Welfare (ISEW) for Thailand over a twenty-five year period, 1975–1999. This paper concludes that even low-middle income countries are beginning to approach the point at which economic growth produces both diminishing and, at times, negative welfare returns as the costs of achieving growth begin to outweigh the associated benefits. These results are important for policy makers and highlight the importance of widening policy prescriptions in order to increase social welfare. However, the policy guidelines that are suggested must be critically accepted before being adopted due to possible weaknesses of the ISEW approach.

Comparative analysis of student perceptions : impact on satisfaction among international postgraduate students from China, India, Indonesia and Thailand

The paper undertakes a comparative analysis of the gap in student expectations and perceptions on key service quality factors influencing the choice of Australia as a study destination by international postgraduate students of Asian origin and their relationship with student satisfaction. Based on the theoretical framework of expectancy-disconfirmation paradigm, the paper examines the differences in student perceptions of the level of service quality related to the key factors of choice among four groups of students from China, India, Indonesia and Thailand using structural equation modelling, ANOV A and MANOV A. It concludes with strategic implications for universities.

Evidence for crossvergence in the perception of task and contextual performance : a study of western expatriates working in Thailand

The applicability of the Western model of task and contextual performance to the context of Thai and Western managers, professionals and consultants working together in Thailand is addressed in this research. The results show a clear difference in the factor structure of how Western and Thai managers perceive the importance of performance factors. Moreover, the task and contextual factor structure found for Western managers working in a Western culture did not hold for Westerners working within the Thai cultural environment. These findings provide evidence of adaptation by the Westerner to the Thai cultural environment, supporting the notion of crossvergence.

Micropayments and e-commerce transactions : Thailand

Online payments in electronic commerce (e-commerce) are usually carried out with credit cards because they are the most convenient to use. Web sites that do not accept credit cards risk losing their customers. Yet potential customers do not include only credit card holders. There are a lot of potential customers who do not have credit cards, some for cultural reasons, others because of trust implications and others because of cost. Even among those who have credit cards, some do not buy online just because they do not feel that the system is secure enough to give away their credit card information over web pages. More importantly perhaps, credit card payments are not suitable for small-value purchases due to their high-incurred overheads to merchants.
