A participatory rural appraisal (PRA) conducted in East Timor in 2004 as part of an agricultural development project provided the basis for a number of community-based participatory extension initiatives. The PRA involved several communities throughout a watershed and also served as a training exercise for local agriculture ministry staff. Despite the poverty of many of the communities involved, and in contrast to published literature on the local agricultural situation, farmers clearly expressed their need for more marketable crops and alternative sources of livelihoods. Their desires contrasted with the project's initial assumption that the major need was for increased production of staple crops to alleviate food scarcity. The project consequently branched out from concentrating on basic agronomy of staple crops into developing marketable crops, improving livestock production and facilitating development of a local business. Farmers' groups were set up to allow farmers to develop their own agricultural enterprises. Some ministry staff who participated in the project welcomed the opportunity to move from the traditional authoritarian extension system set up under Indonesian colonial rule to a more collegial and educational system. The breakdown of institutions and lines of authority following independence may create new opportunities for participatory development in newly independent states.  相似文献

Bunk beds have long been recognised as a potential source of injury to children. This study was undertaken to establish an evidence base for a proposed injury reduction program and to determine whether or not there is a case for a mandatory safety standard. Recent literature on bunk bed safety was reviewed to provide an overview of the injury issues involved. Major sources of relevant Australian and international data were identified and the available data summarised. An in-depth analysis of Victorian data was undertaken to identify the nature and severity of injuries sustained and any patterns or trends, including age profiles. It is estimated that, in Australia, in the under fifteen age-group, there are at least 2,100 bunk bed-related injuries treated annually by hospital emergency departments. This represents a rate of about 50 injuries per 100,000 age-specific population. The majority of these injuries (86%) occur in children under the age of 10 years with injuries peaking in the 5-9 year age-group. The main cause of non-fatal injury is falls from the top bunk resulting in a fracture (33%), mainly to the upper extremity (75%). There have been at least two deaths from asphyxia in Australia in the past 10 years, due to entrapment in the bunk structure. It is clear from the current evidence that bunk bed injuries are a significant problem in Australia and represent a life-threatening hazard to young children in particular. The existing voluntary Australian/New Zealand Standard adequately addresses the safety issues raised by the examination of the literature and the analysis of the injury data. It is also clear that, in Australia, voluntary standards and the market place have been ineffective in achieving compliance. It is therefore recommended that the Australian Standard be made mandatory in an effort to significantly improve the safety of bunk beds in Australia.  相似文献

This article integrates marketing and social psychology theories and findings into a conceptual model that describes the conditions for which idealized advertising images induce positive (or negative) consumer outcomes. Extending Bessenoff's moderated mediation model, the authors propose that: (1) effect of social comparison on the relationship between exposure to idealized advertising images and psychological/emotional outcomes will be moderated by internalization of ideals and self-discrepancy; (2) effect of psychological/emotional outcomes on the relationship between social comparison and consumer vulnerability will be moderated by attainability of ideals; and (3) product claims should moderate the relationship between psychological and emotional outcomes and consumer vulnerability.  相似文献

This paper examines empirically the influences on managerial remuneration in a sample of 97 UK small and medium-sized enterprises (SMEs). The empirical analysis, based on data obtained from interviews with middle (i.e. non-director level) managers and the published financial records of their employing firms lodged at Companies House, examines the relative explanatory power of a number of human capital, job/firm specific and external labour market variables. In addition, the sample was partitioned into two groups, one comprising 29 financial managers and the other comprising 68 non-financial managers. Separate wage equations were estimated for the two groups to determine whether the factors that influence remuneration differ between the two groups of managers. For the overall sample, the results indicate that the managers' ages, qualifications and previous careers and the size, growth, industry and location of their employing firms are able to explain a large proportion of the variance in remuneration. For the sub-sample analyses, firm profitability, (several aspects of) size, and the managers' career histories are of relatively greater importance in respect of financial managers' remuneration, whilst asset growth, industrial sector and location seem to be of more importance for the non-financial managers. These results are viewed as being broadly consistent with the expectations derived from the extant theoretical and empirical literatures on managerial remuneration.  相似文献

Durand et al. (2006a ) argue that the Australian market is both internationally integrated and domestically segmented. They find that the US‐based three‐factor model captures returns of the largest stocks in Australia (evidence of international integration), but that it is unable to account for the returns of the smallest stocks (evidence of domestic segmentation). This study resolves the puzzle left by Durand et al. (2006a) . Incorporating a liquidity factor provides the missing link in their analysis: it results in a model that permits both the international integration of the largest stocks and the model can account for the returns of the smallest stocks. Our analysis highlights the important role of liquidity in Australian asset pricing.  相似文献

This paper identifies the effectiveness of a simulated treasury dealing room for teaching and learning. It uses a presurvey and a postsurvey to establish student perceptions of learning effectiveness. It concludes that students believe that the dealing room: (i) improves their opportunities to apply theory; (ii) provides better learning than lectures; (iii) is more effective than individual learning; (iv) improves student monitoring of learning effectiveness; and (v) improves student abilities to recognize ethical issues, develop alternative solutions to ethical problems, and evaluate solutions to ethical problems from a moral point of view. Student motivation is enhanced by: (i) the high value they place on dealing room learning; (ii) their preparedness to participate; (iii) rapidly reduced levels of anxiety about trading; and (iv) the learning resources provided.  相似文献

The Law and Economics of Costly Contracting   总被引:1,自引:0,他引:1  
In most of the contract theory literature, contracting costsare assumed either to be high enough to preclude certain formsof contracting or low enough to permit any contract to be written.Similarly researchers usually treat renegotiation as eithercostless or prohibitively costly. This article addresses themiddle ground between these extremes, in which the costs ofcontracting and renegotiation can take intermediate values andthe contracting parties can themselves influence these costs.The context for our analysis is the canonical problem of inducingefficient relation-specific investment and efficient ex posttrade. Among our principle results are: (i) The efficiency andcomplexity of the initial contract are decreasing in the costto create a contract. Hence the best mechanism design contractscan be too costly to write. (ii) When parties use the simplercontract forms, they require renegotiation to capture ex postsurplus and to create efficient investment incentives. In somecases, parties want low renegotiation costs. More interestingis that, in other cases, parties have a strict preference formoderate renegotiation costs. (iii) The effect of contract lawon contract form is significant but has been overlooked. Inparticular, the law's interpretive rules raise the cost of enforcingcomplex contracts, and thus induce parties to use simple contracts.Worse, the law also lowers renegotiation costs, which furtherundermines complex contracts and is also inappropriate for someof the simpler contracts.  相似文献

Does increasing the minimum wage lead to employment losses? For many years most economists thought that the answer to this was a straightforward ‘yes’. However, research during the 1990s began to overturn this conventional wisdom and showed that increases in the minimum wage did not automatically lead to employment losses. A recent Australian study, by Leigh (2003), examined the impact of statutory minimum wages in Western Australia and reached conclusions which supported the conventional view. However, close scrutiny of Leigh's article shows that it is fundamentally flawed. Despite Leigh's efforts, it remains the case that we simply do not know a great deal about the employment impact of Australia's system of minimum wages.  相似文献

Traditionally the codomain of a utility function is the set of real numbers. This choice has the advantage of ensuring the existence of a continuous representation but does not allow to represent many preference structures that are relevant to utility theory. Recently, some authors have started a systematic study of utility representations that are not real-valued, introducing the notion of a Debreu chain. We continue their analysis defining two Debreu-like properties, which are connected to a local continuity of a utility representation. The classes of locally Debreu and pointwise Debreu chains here introduced enlarge the class of Debreu chains. We give several examples and analyze some properties of these two classes of chains, with particular attention to lexicographic products.  相似文献
