Reducing adolescent substance use is important in South Africa, a developing nation with increasing adolescent substance use, lack of leisure/recreation opportunities, and high rates of adolescent discretionary time. Previous research suggests leisure boredom and adolescent substance use co-occur in this setting. Using longitudinal data from 2,580 South African adolescents as they progressed from the 8th to 11th grade, the current study disentangles the associations of trait and state leisure boredom with substance use, and examines how ability to restructure boring situations moderates those associations. On average, individuals with higher trait boredom used more substances, and on occasions when state boredom was high, the prototypical adolescent used more substances. Although restructuring did not moderate these associations, greater ability was associated with lower substance use independent of leisure boredom. Findings illustrated the importance of considering how trait and state aspects of leisure may contribute to adolescents’ risk behavior and addressed through preventive intervention. 相似文献
Much past research on ownership policy has dealt with foreign subsidiaries. In this paper, we study the ownership relationship between Japanese firms and their publicly-traded domestic subsidiaries. Using a transaction cost framework, we find that benefiting from high subsidiary profitability is not the sole motivation behind parent firms' decisions regarding equity control of their subsidiaries. Our results indicate that different policies are adopted by Japanese firms with respect to domestic and foreign subsidiaries. 相似文献
The role of entrepreneurs in stimulating growth in the small business economy has received significant interest in the last three decades. This growing interest is prompted, in part, by the government’s assumption that the establishment and expansion of existing small firms could be greatly enhanced by the promotion of entrepreneurial education programmes in colleges and universities. Whilst there has been significant interest in the role, type and effect of entrepreneurs in the economy, few studies have examined the effect of entrepreneurial programmes on the progression of an idea through to commercialisation. This is because such research, whilst seemingly desirable, is problematic. Evidence can be gleaned through the development of suitable conceptual frameworks and methods, to assess the role and impact of entrepreneurial programmes on the commercialisation of products or processes, and the enhancement of entrepreneurial capabilities. To address this problem, the research will examine different approaches and frameworks that have been developed and applied hitherto. The objective of this will be to highlight the difficulties in assessing the motivations, cognitive and behavioural changes of entrepreneurs. Also, the research will demonstrate the need to undertake adequate controls, which illustrate possible improvement in entrepreneurial capabilities, networks, and credibility in comparison to students that embarked on courses without entrepreneurial elements. The process will confine itself to business development within the higher education (HEI) context. The MSEC has as its remit to provide opportunity, education, awareness and training to foster entrepreneurship within science and engineering departments across four universities in Greater Manchester. This setting will provide a unique situation in which to investigate the development of germinal technology businesses from the inception of an idea to the point of incubation, prototype development and investment. There is a requirement to understand the needs of the virgin entrepreneur, possible obstacles to commercialisation and the process of new venture creation. The methodology to be adopted has been identified, and forges new ground on combining positivist and phenomenological paradigms. The multi–paradigm approach supports the use of critical incident technique to reveal greater insights in to the personal and cognitive development of virginal entrepreneurs, the suitability of enterprise programmes to act as catalysts for venture creation, and their role in supporting technology transfer. The research will not only confine itself to examining undergraduate and postgraduate projects within MSEC’s business creation unit, but will also continue to assess the experience of entrepreneurs’ when they leave the programme. The research also documents the economic contribution of the programme, in terms of generation of new technology–based firms and the impact of entrepreneurs joining established small firms. Ultimately the aim is to build a long–term picture of the role of enterprise programmes in HEIs that will inform policy and practice. 相似文献
Summary It has been argued that Léon Walras did not have a theory of economic tatonnement but was instead concerned with a technique of mathematical iteration for the purpose of finding the solutions to the equations of a model of general equilibrium, that his work lacks an account of a means whereby prices are changed, and that he was uninterested in real economic adjustment processes. It is concluded that those judgments are incorrect. It is shown that Walras wanted to develop a realistic theory of time-consuming economic tatonnement in a freely competitive economy, and that he based it on his theories of how prices are changed, of iterative pricing, of entrepreneurial iterative behavior, and of a presumed convergence of the variables to equilibrium.I am grateful to Indiana University of Pennsylvania for a grant that made possible the preparation of this article. 相似文献
Research on international differences in retail productivity has highlighted formidable environmental barriers to the ‘industrialisation’ of mass retailing as a driver of declining British interwar productivity growth in this sector (and in services more generally). We examine evidence for such barriers, using a case study of a firm that built its interwar expansion strategy on ‘American’ retail methods – Marks & Spencer (M&S). We find that, rather than facing barriers to the adoption of American mass retail practices, M&S reaped major productivity gains from this process. This adds further evidence to an emerging literature rejecting the barriers to industrialisation thesis for retailing. 相似文献
Purpose: The purpose of this study is to develop a model of motives and career choice based on learning styles in order to apply the model in teaching business. Although the relationship between learning and McClelland’s (1961) three motives (achievement, affiliation, and power) as confirmed that motives are “learned,” little research has examined if learning styles are the key factor to classify motivation into three different implicit motives and whether those motives affect students’ career choice.
Design: The article first examines the Kolb’s (Kolb, 1984, 1999; Kolb & Kolb, 2005) learning styles including active experimentation (AE), reflective observation (RO), abstract conceptualization (AC), and concrete experience (CE). It then measures the learning styles and Holland’s (1985) six career types including realistic, investigative, artistic, conventional, enterprising, and social by the three McClelland (1985) motives including achievement, power, and affiliation using Linguistic Inquiry and Word Count (LIWC) 2015 software (Pennebaker, Booth, Boyd, & Francis, 2015). Finally, the article compared the factors of learning styles and career types against each other based on the three motives in order to discuss the teaching strategies for students in their career choice.
Methodology: The study has used LIWC 2015 (Pennebaker et al., 2015) software to find the scores of achievement, power, and affiliation motives in the four Kolb’s learning styles (Kolb, 1984, 1999; Kolb & Kolb, 2005), and the six career interests (Holland, 1985). Correlation analysis was conducted among the motive values to find the relations among the learning styles, motives, and career choice.
Findings: (a) The two learning styles of AC and AE stimulate the need for achievement; (b) the learning style of RO stimulates the need for power; (c) the learning style of CE stimulates the need for affiliation; (d) people with a high achievement motive would be fit in artistic, investigative, and realistic careers; (e) people with a high power motive would be fit in conventional and enterprising careers; (f) people with a high affiliation motive would be fit in a social career.
Originality of the research: Efficient teaching techniques applied based on the study findings indicate that (a) teaching high achievement students will use more challenge techniques such as assignments and projects for thinking and doing training, (b) teaching high power students will use more control techniques such as discussions and presentations for observation training, and (c) teaching high affiliation students will use more socially oriented techniques such as writing tasks for emotion training. 相似文献
In recent years, a growing number of small-to-medium-enterprises are embracing wind turbine projects not only as part of their cost reduction strategy but also to actively play their part in the global fight against climate change. However, it would appear there are currently limited empirical studies carried out in this emerging industry. This case study analyses the cost effectiveness of one such wind turbine initiative by a company in the Republic of Ireland, who invested in a 300 kW embedded wind turbine project at the end of 2013. The research methodology which is primarily a case study analysis included comparing historical electricity utility bills which allowed the 2013 quantity of electrical energy units imported, i.e. the year before the turbine was installed to be compared with the 2014 value, i.e. the year after the turbine was installed. Numerous site visits were undertaken over a four-year period, during which electric meter readings were recorded and stored. The findings of this piece of research indicate that the installation of the embedded wind turbine had minimal positive effect on the annual electricity costs for the company. Indeed the turbine appears to have significant negative effects such as a need for an increased maximum import capacity and also it appeared to contribute to a deteriorating utility power factor. While the aesthetic nature of the on-site turbine seemed to create a positive image of the company, it would appear that caution should be exercised when business owners select alternative energy providers who claim to be experts in the energy field but may have limited knowledge in this area of wind energy, which as of yet has minimal robust research into all aspects of its benefits/attributes. 相似文献
President Donald Trump espouses “America First” positions which are commonly interpreted as protectionist. However, a closer reading of Donald Trump’s business interests, of his administration’s published trade agenda and of US trade negotiation history calls into question whether “America First” means protectionism. Trump will use large trade deficits to pressure trading partners to further open up their markets. Companies that are successful in exporting to the US market from those countries will be alarmed by protectionist announcements and will therefore most likely pressure their governments to give in to the demands of the Trump administration. 相似文献
International traders frequently use forward exchange transactions to hedge their cash flows in foreign currencies. A key issue is whether the forward rates are efficiently priced. There is evidence of time-varying risk premia in forward exchange rates. Are these risk premia systematic or unsystematic? This article uses a market model to explain risk, implying that the risk premium in the forward rate varies pari passu with the beta of the return to speculative forward positions. Assuming the unobserved risk premium is proportional to the forward premium allows testing the predicted relations; the data reject the joint hypotheses of the model and systematic risk. In terms of a simple factor model explaining the covariation of the forward premium, the risk premium, and the expected percentage rate of change of the spot exchange rate, the assumption that the forward premium and the risk premium are proportional can be relaxed without changing the empirical results. 相似文献
Using data for a one-year period from the Kingston Public Hospital (KPH) in Jamaica, we describe patterns of non-fatal violence-related injuries, and carry out simulation analysis to estimate rates of hospital admission under various injury reduction scenarios, and the potential savings that can be realized by reducing violent crimes. In this period there were 6107 registered violence-related visits to the KPH representing 11.5% of all recorded visits. Of these 16.6% (1001) were admitted. The most common methods of inflicting injury was by stabbing (52.1%), blunt injuries (37.9%) and gunshot wounds (7.3%). Multivariate analyses indicated that gunshot injuries, stab injuries, being male between the ages of 15 and 44 years, receiving the injury in November or December, and being injured by a stranger or unknown assailant, were significant correlates of a higher probability of admission. Simulation analysis with various injury reduction scenarios indicated decreases in the probability of admission ranging from 12% to 44%, with estimated savings of up to 31% of the annual supplies budget of KPH. 相似文献
