In this article, we explore subcultural interaction in the context of attempts by executives to control culture in the unusual organisational setting of football. We present evidence of five tension points in subcultural relations (togetherness or isolation, internal labour market, multiple identification and allegiances, individual and organisational requirements, and competition and cooperation). We examine how these tensions were induced and or exacerbated by the culture management efforts, as well as the ways in which the dynamics of change impacted on the objectives of executives. The article concludes with a discussion of the implications of the findings for theory and practice. 相似文献

We examine the behavior of stock market prices in several African countries by means of fractionally integrated techniques.
In doing so, we can test for mean reversion in these markets. Our results can be summarized as follows: we cannot find evidence
of mean reversion in any single market, and evidence of long memory returns (i.e., orders of integration above 1 in the logged
stock prices) is obtained in the cases of Egypt and Nigeria, and, in a lesser extent in Tunisia, Morocco and Kenya. Permitting
the existence of a structural change, the break dates take place in the earlier 2000s in the majority of the cases, and evidence
of mean reversion seems to have taken place in the periods before the breaks in most of the countries. If we focus on the
absolute and squared returns, evidence of long memory is obtained in Nigeria and Egypt. Thus, for these two countries, a long
memory model incorporating positive fractional degrees of integration in both the level and the volatility process should
be considered. 相似文献

In Project STAR, 11,571 students in Tennessee and their teachers were randomly assigned to classrooms within their schools from kindergarten to third grade. This article evaluates the long-term impacts of STAR by linking the experimental data to administrative records. We first demonstrate that kindergarten test scores are highly correlated with outcomes such as earnings at age 27, college attendance, home ownership, and retirement savings. We then document four sets of experimental impacts. First, students in small classes are significantly more likely to attend college and exhibit improvements on other outcomes. Class size does not have a significant effect on earnings at age 27, but this effect is imprecisely estimated. Second, students who had a more experienced teacher in kindergarten have higher earnings. Third, an analysis of variance reveals significant classroom effects on earnings. Students who were randomly assigned to higher quality classrooms in grades K–3—as measured by classmates' end-of-class test scores—have higher earnings, college attendance rates, and other outcomes. Finally, the effects of class quality fade out on test scores in later grades, but gains in noncognitive measures persist. 相似文献

This article seeks to evaluate the appropriateness of a variety of existing forecasting techniques (17 methods) at providing accurate and statistically significant forecasts for gold price. We report the results from the nine most competitive techniques. Special consideration is given to the ability of these techniques to provide forecasts which outperforms the random walk (RW) as we noticed that certain multivariate models (which included prices of silver, platinum, palladium and rhodium, besides gold) were also unable to outperform the RW in this case. Interestingly, the results show that none of the forecasting techniques are able to outperform the RW at horizons of 1 and 9 steps ahead, and on average, the exponential smoothing model is seen providing the best forecasts in terms of the lowest root mean squared error over the 24-month forecasting horizons. Moreover, we find that the univariate models used in this article are able to outperform the Bayesian autoregression and Bayesian vector autoregressive models, with exponential smoothing reporting statistically significant results in comparison with the former models, and classical autoregressive and the vector autoregressive models in most cases. 相似文献

Abstract We investigate the impact of alternative certifying institutions on firms’ incentives to engage in costly Corporate Social Responsibility (CSR) activities as well as their relative market and societal implications. We find that the CSR certification standard is the lowest under for‐profit private certifiers and the highest under a Non Governmental Organization (NGO), with the standard of a welfare‐maximizing public certifier lying in between. Yet, regarding industry output, this ranking is reversed. Certification of CSR activities is welfare enhancing for consumers and firms and should be encouraged. Finally, the market and societal outcomes of CSR certification depend crucially on whether certification takes place before or after firms’ CSR activities. 相似文献

This study explores the factors that account for the environmental performance of hotels in the special context of a developing country, Ghana. It also examined the socio-demographic characteristics of managers and organizational characteristics that determine the environmental performance of Ghanaian hotels. A stratified random sampling method was employed to survey 200 hotel managers from different categories of hotels in Accra. Ninety-four per cent were independent, and Ghanaian-owned. Sixty-seven per cent had fewer than 20 rooms; only 45 had more than 100 rooms. Only 11.6% were affiliated to foreign multinational companies in any way. Six key factors that accounted for the environmental performance were extracted from a factor analysis. They included, in order of most practised, the environmental education and training for staff, measures to support for the host community, conservation project support, compliance with environmental regulations, waste management, and voluntary programmes. A hierarchical multiple regression analysis indicated that larger size and better class of hotels, as well as those with membership of the national hotel trade association, had better environmental performance as did hotels with better paid managers. Affiliation to foreign multinational chains did not predict better performance. A series of suggestions are made to improve the environmental performance of Ghana's hotels. 相似文献

Several studies have examined the impact of remittances on economic growth, yet the results remain largely inconclusive. I present an analysis of the relationship between remittances and per capita growth, and investigate whether the impact of remittances on growth is through capital accumulation or other mechanisms. Using data for sub-Saharan African countries and dynamic empirical models, I find that there is a positive relationship between remittances and growth, as well as a positive interaction effect between remittances and financial depth on growth. The findings also reveal threshold values for two main indicators of financial development, above which the total effect of remittances on growth is positive. The results further provide evidence for the existence of an investment channel through which remittances affect growth, and indirect evidence that remittances contribute towards a stable macroeconomic environment, and hence, growth, through a consumption smoothing effect. 相似文献
