This paper reports on the needs identified by three teachers during an investigation into their first experiences of implementing
technology in their primary classrooms. One part of one teacher's case is presented in detail to illustrate that the meanings
the teachers made of their experiences were related very closely to their beliefs about teaching and learning, to their understanding
of technology as a phenomenon and to the place they saw technology having within the whole curriculum. One particular outcome
of the investigation was that the teachers experienced a lack of knowledge of the scope and breadth of the technology learning
area, and as a consequence, faced challenges in planning for the successful implementation of activities. In response to this
particular need and to the many issues emanating from current research literature in technology education, the paper then
presents two models for conceptualizing and planning units of work in technology in primary classrooms. The models form frameworks
that may be useful to help structure thinking for authentic classroom planning and sequencing of lessons or learning experiences.

Despite the fact that some sectors of industry are facing major skills shortages, the Scottish labour market continues to be characterised by occupational segregation and a large disparity between the wages of women and men. The concentration of individuals in occupations and training based on their gender effectively restricts the pool of potential recruits to industry and is unlikely to make the best use of human capital. Moreover, it obstructs the pursuit of gender equality by reinforcing the gender pay gap and restricting individual career choices. This paper reports on the government's flagship training policy, the Modern Apprenticeship programme, from a gender perspective. It concludes that, ten years on from its introduction, the scheme represents something of a 'missed opportunity' to tackle occupational segregation and its deleterious effects in the wider economy and in society at large. It is recommended that the government and organisations involved in the development and delivery of Modern Apprenticeships adopt a more conscious and cohesive approach to promoting non-traditional choices at the vocational level. 相似文献

This paper discusses the need for developing consistent public agricultural policies for Canada. Six "realities" of today are discussed and are proposed as guidelines for public involvement in Canadian agriculture. The guidelines are indicated to be applicable not only to public policy for agriculture, but also to other sectors, and are believed to be relevant well beyond a decade.
QUELQUES LIGNES DIRECTRICES CONCERNANT LA POLITIQUE AGR1COLE DES DIX PROCHAINES ANNÉES – L'article qui suit analyse pour le Canada la nécessité d'une véritable politique agricole. Dans cet ordre d'idées. six "schémas" qui pourraient constituer les lignes directrices d'une intervention des pouvoirs publics dans l'agriculture canadienne sont discutes et proposés. Ce cadre d'analyse pourrait être appliquée non seulement aux politiques agricoles mais aussi à d'autres secteurs et nous croyons qu'il serait valable bien au-delà d'une décade. 相似文献

This paper solves numerically the intertemporalconsumption and portfolio choiceproblem of an infinitely-lived investor whofaces a time-varying equity premium.The solutions we obtain are very similarto the approximate analytical solutionsof Campbell and Viceira (1999), except atthe upper extreme of the state spacewhere both the numerical consumption andportfolio rules flatten out.We also consider a constrained version ofthe problem in which the investor facesborrowing and short-sales restrictions.These constraints bind when the equitypremium moves away from its mean in eitherdirection, and are particularly severe forrisk-tolerant investors. The constraints havesubstantial effects on optimalconsumption, but much more modest effects onoptimal portfolio choice in theregion of the state space where they are notbinding. 相似文献

We examine a sample of 443 bank mergers between publicly traded banks announced during the 1990s to investigate empirically the role of full interstate banking deregulation. The pre‐deregulation 1990s are characterized by value creation, with mergers involving a high degree of branch overlap experiencing significant announcement gains. Bank mergers in the post‐deregulation 1990s, however, fail to create value, and mergers with a high degree of branch overlap actually experience significant losses. Consistent with prior research, these valuation consequences are magnified for large bank mergers in the 1990s. Overall, our results are consistent with the broader literature on corporate control, suggesting that an economic shock can materially alter industry structure and the economic rationale for the efficient reallocation of assets through merger activity. 相似文献

This paper studies the impact of a conditional cash transfer programme in Colombia on the total consumption of very poor households and on its components. Our evaluation methodology involves comparing household expenditures in areas in which the programme was not implemented (control) and those in which it was (treated). We use a quasi‐experimental approach, as the Familias en Acción programme was not randomly assigned across localities, for political reasons. We condition on a large range of household‐ and municipality‐level characteristics, and also control for pre‐programme differences in the outcomes of interest using a differences‐indifferences methodology. We find that the programme has been effective at greatly increasing total consumption and its main component, food consumption, in both rural and urban areas. The programme has also contributed to improvements in the quality of food consumed, in particular of items rich in proteins (milk, meat and eggs) and of cereals. Furthermore, the programme has created redistributive effects in favour of children through expenditure on education and children's clothing, while it has not significantly affected consumption of adult goods such as alcohol and tobacco or adults’clothing. 相似文献

This article argues that if stakeholding has any validity, then the family should be numbered among the stakeholders. It then goes on to discuss how the family's stake in the firm could be distinguished from its stake in society and suggests ways in which the family's stake could be embodied. 相似文献

Efficient tests of stock return predictability 总被引:1,自引:0,他引:1
Conventional tests of the predictability of stock returns could be invalid, that is reject the null too frequently, when the predictor variable is persistent and its innovations are highly correlated with returns. We develop a pretest to determine whether the conventional t-test leads to invalid inference and an efficient test of predictability that corrects this problem. Although the conventional t-test is invalid for the dividend–price and smoothed earnings–price ratios, our test finds evidence for predictability. We also find evidence for predictability with the short rate and the long-short yield spread, for which the conventional t-test leads to valid inference. 相似文献
