On the basis of strike statistics it has been argued that Northern Ireland has a more harmonious industrial relations climate than Great Britain. Here the author compares its strike pattern with that of the UK as a whole and explains why Northern Ireland should be seen as a relatively strike prone region.  相似文献

Asymmetry tests have been used by agricultural economists to determine if the effects of price changes in one region or level in the marketing channel are transmitted to other regions or levels in the marketing channel in an identical manner for price increases and decreases. Two tests are normally conducted: sum of coefficients tests and speed of adjustment tests. In this analysis, these two tests are conducted on weekly price response equations that relate Alberta and Ontario price changes. Six separate periods of analysis are used to reflect institutional changes in the Alberta market. Evidence of asymmetrical price response is detected for the period immediately preceding the establishment of the Alberta Pork Producers Marketing Board.
Les spécialistes en économie rurale vérifient i'asymétrie des prix pour voir si la fluctuation des cours dans une région ou un élément du circuit se transmet aux autres régions ou éléments de la même façon pour les hausses et les baisses de prix. On effectue habituellement deux épreuves: (1) somme des résultats des épreuves sur les coefficients et (2) vérification de la rapidité d'ajustement. Les auteurs ont appliqué ces deux épreuves aux équations qui mesurent la réaction des prix hebdomadaires et relient les fluctuations des prix entre l'Ontario et l'Alberta. lis se sont servis de six périodes d'analyse distinctes pour tenir compte des changements institutionnels survenus sur le marché albertain. Les résultats indiquent une réaction asymétrique des prix pour la période qui a immédiatement précédé la création de l'Office de commercialisation des producteurs de pores de l'Alberta.  相似文献

Neural networks are nonlinear mapping structures based on the study of the human brain. They have been shown to be universal and highly flexible junction approximators to any data-generating process. Therefore, they are powerful models for forecasting purposes, especially when the underlying data-generating processes are unknown. However, the appropriate design of the network's architecture and learning rules are crucial for obtaining satisfactory results. This study discusses the scope and limitations of neural networks for forecasting problems and provides an example by designing a neural network for forecasting. It is argued that statistical theory can offer some suggestions for designing an optimal network architecture. An example comparing a neural network and ARIM model for forecasting weekly corn prices 1974 through 1993 is provided. Results show the neural network model to be more accurate than the ARIMA.  相似文献

This paper analyses the dimensions and determinants of trade union growth in Northern Ireland. Aggregate membership, mostly in Great Britain-based unions, has grown more rapidly than the UK average in recent decades, largely due to a massive shift of employment into public sector services, where trade union density is higher.  相似文献

A bstract . In the early twentieth century, the African American (AA) populations of northern cities grew rapidly, whereas the foreign-born white populations of these cities stabilized. Stanley Lieberson has hypothesized that, in these cities, the resulting shifts in the ethnic composition negatively affected the economic prospects of AAs. The present study shows that the transformation of business enterprise among AAs in the urban North during 1900-1930 is consistent with this hypothesis. Census data and evidence from historical case studies suggest that the above demographic changes affected two trends: 1) a decline in the concentration of AAs in entrepreneurial occupations which served whites and 2) an increase in their concentration in entrepreneurial occupations serving other AAs.  相似文献

Set in the context of an expansion of scrutiny by local authorities of local service provision, this article explores the key challenges ahead for managers and politicians in this area of local governance. Drawing on an evaluation of the development of health scrutiny, it outlines the different types of activities health scrutiny committees are engaging in to fulfil their legislative commitments and suggests lessons for the expansion of external scrutiny.  相似文献

Little is known about what distinguishes managerial thought and practice in successful councils, as opposed to poorly-performing or failing organizations. Managers in high-performing councils in England were interviewed about their improvement practices. Their responses highlighted the importance of an in-depth understanding of customers, staff and the organizational environment; coupled with an inspiring vision of a better future. A commitment to learning was fundamental, forming the basis for an ‘intelligent application’ model of the improvement process.  相似文献

The recognition of entrepreneurship as a solution to, rather than a cause of, environmental degradation and social inequality moved the field to identify a new type of entrepreneurial activity, namely sustainable entrepreneurship. Scholarly interest has spiked in recent years; however, aside from its aspirational appeal, there remains a lack of understanding of the nature of the phenomenon and the future of sustainable entrepreneurship in theory and practice. This review seeks to provide a conceptual basis for stimulating scholarly thought and improving our collective understanding of sustainable entrepreneurship as a distinct subdomain within entrepreneurship research. Based on boundary definition and delineation of main features, this review critically discusses the main challenges ahead and elaborates on the research implications and future research directions beyond current, dominant approaches to entrepreneurial action.
