Perceived Parental Control,Restructuring Ability,and Leisure Motivation: A Cross-Cultural Comparison
Hui “Jimmy” Xie Linda L. Caldwell John W. Graham Elizabeth H. Weybright Lisa Wegner Edward A. Smith 《Leisure Sciences: An Interdisciplinary Journal》2013,35(4):319-335
ABSTRACTLeisure is viewed worldwide as an important developmental context for adolescents. As leisure research and programs are shared across nations, it is crucial to examine the cultural equivalence of leisure-related constructs and how they are related. Grounded in self-determination theory, this study explored the influence of perceived parental control and leisure restructuring ability on leisure motivation (amotivation and autonomous motivation) using samples of eighth grade adolescents in the United States and South Africa. Results of multiple-group structural equation modeling showed that the measurement model of the constructs was equivalent across the two samples, but the determinants of leisure motivation differed between the two samples. The findings provide implications for future cross-cultural research in leisure and offer insights on design and adaptation of leisure-based intervention and education programs in different cultural contexts. 相似文献

This study identifies three conceptual and theoretical frameworks (free market, social engineering, and social transformation) within which the significance of gender and race to entrepreneurship and business are examined, particularly within the South African context. There are no comprehensive data sets on ownership patterns by gender and race for salaried workers or the millions of micro- and small-scale entrepreneurs in the “second” (informal) economy during and after the apartheid era in South Africa, but most agree there has been little change. However, due to government compliance programs, such as Black Economic Empowerment in the 2000s, and good monitoring of its fulfillment, there have been advances for women and blacks in formal-sector private companies and state-owned enterprises, as illustrative data given here show. The conclusion is that the social transformation (political economy) approach best captures the complex interplay of these factors, especially on gender issues and entrepreneurship, where fundamental social change becomes a possibility. 相似文献

ABSTRACTThis study tests for MDH in two prominent foreign exchange (FX) markets in Africa, Nigeria and South Africa using three benchmark currencies (euro, dollar and pound sterling). Data utilized cover time series closing rate data set of five-day weekly frequency spanning December 14, 2001 to September 26, 2014. The study considers both the linear and nonlinear measures for MDH with better size and power properties. We also capture structural break endogenously from the data stream using Perron (2006) unit root test with structural break. Three striking findings are discernible from our analyses. First, on average, the South African FX market appears to be more efficient than the Nigerian FX market. Thus, the latter may be more susceptible to speculations than the former. Second, ignoring significant structural breaks may render statistical inferences invalid. Third, the choice of methodology does matter when testing for MDH of foreign exchanges in Africa. 相似文献

Connecting science with policy has always been challenging for both scientists and policymakers. In Ghana, Mali and Senegal, multi-stakeholder national science-policy dialogue platforms on climate-smart agriculture (CSA) were setup to use scientific evidence to create awareness of climate change impacts on agriculture and advocate for the mainstreaming of climate change and CSA into agricultural development plans. Based on the platforms' operations and achievements, we used semi-structured questionnaire interviews and reviewed technical reports produced by the platforms to analyse how their modes of operation and achievements improve understanding of the science-policy interfaces between agricultural and climate change decision making. Results showed that these platforms constitute an innovative approach to effectively engaging decision-makers and sustainably mainstreaming climate change into development plans. Effective science-policy interaction requires: (a) institutionalizing dialogue platforms by embedding them within national institutions, which improves their credibility, relevance and legitimacy among policymakers; (b) two-way communication, which contributes substantially to the co-development of solutions that address climate change vulnerabilities and impacts; and (c) relevant communication products and packaging of evidence that aligns with country priorities, which facilitates its uptake in policy-making processes. We conclude with a framework of sustainable operation for such platforms based on lessons learnt in the three countries. 相似文献

In response to the declining soil fertility in southern Africa and the negative effects that this leads to, such as food insecurity besides other developmental challenges, fertilizer tree systems (FTS) were developed as technological innovation to help smallholder farmers to build soil organic matter and fertility in a sustainable manner. In this paper, we trace the historical background and highlight the developmental phases and outcomes of the technology. The synthesis shows that FTS are inexpensive technologies that significantly raise crop yields, reduce food insecurity and enhance environmental services and resilience of agro-ecologies. Many of the achievements recorded with FTS can be traced to some key factors: the availability of a suite of technological options that are appropriate in a range of different household and ecological circumstances, partnership between multiple institutions and disciplines in the development of the technology, active encouragement of farmer innovations in the adaptation process and proactive engagement of several consortia of partner institutions to scale up the technology in farming communities. It is recommended that smallholder farmers would benefit if rural development planners emphasize the merits of different fertility replenishment approaches and taking advantage of the synergy between FTS and mineral fertilizers rather than focusing on ‘organic vs. inorganic’ debates. 相似文献

Systems of urban and peri-urban agriculture (UPA) take many forms in terms of integration of different activities, production intensities and production orientations. The present study is aimed at a refined characterization of the diversity in terms of production orientation, resource endowments and production strategies of the different types of farm households involved in urban and peri-urban agriculture in three West African cities. A total of 318 UPA households were surveyed using a standardized semi-structured questionnaire in the West African cities Kano (Nigeria), Bobo Dioulasso (Burkina Faso) and Sikasso (Mali). Through categorical principal component analysis and two-step cluster analysis, six distinct household clusters were identified based on resource endowments and the degree of integration of vegetable, field crop and animal production. Three clusters appeared in all three cities; the remaining three were specific for one of the cities each and comprised (i) commercial gardening plus field crop–livestock (cGCL) keeping, (ii) commercial livestock plus subsistence field cropping (cLsC), (iii) commercial gardening plus semi-commercial field cropping (cGscC), (iv) commercial gardening plus semi-commercial livestock (cGscL) keeping, (v) commercial field cropping (cC) and (vi) commercial gardening (cG). Production constraints were similar across the cities, that is, high costs of inputs, water shortages and lack of fertilizers in the garden and field crop production systems, while feeding constraints and animal diseases were the main constraints in livestock production. UPA remains an important economic activity to livelihood strategy for urban and peri-urban farmers. Appropriate policies should be formulated that efficiently target the site-specific constraints for improving the quality and sustainability of UPA production systems. 相似文献

This paper focuses on rock art tourism, a highly vulnerable heritage of broad public interest, only sustainable within an effective management framework. The paper explores tourism management in South Africa's uKhahlamba-Drakensberg World Heritage Site, inscribed in 2000 for its natural landscapes and its exceptional rock art heritage. In practice, nature dominates the area's tourism and management dynamics. Current tourism patterns, markets and frequencies, together with rock art's low place within tourist agendas, are described. This situation is shown to be a legacy of European Alpine romanticism, and the political rejection of indigenous cultural heritage prior to 1994, still expressed through visitor patterns and marketing policies. Despite rock art needing tourism to valorise its conservation, and being recognised by commentators and the state as a viable route to tourism development, heritage conservation, socio-economic regeneration and cultural empowerment, the failure to reform entrenched and ineffective tourism/conservation governance and management systems is exposed. The problems affecting rock art tourism have allowed the retention of unwelcome values from South Africa's pre-democratic era, risk the loss of World Heritage site status, the destruction of globally outstanding art works and waste an important opportunity to expand and diversify sustainable tourism in South Africa. 相似文献

This article investigates whether large inflows of foreign aid and remittances have had a damaging impact on the Ethiopian Real Exchange Rate (RER). We improve the current empirical literature by: (i) compiling a unique quarterly dataset to provide a larger sample size and enable the modelling of important intra-year dynamics – which should lead to better model specifications; (ii) providing a new empirical approach (Unobserved Components (UC)) to test the ‘Dutch disease’ hypothesis; and (iii) using several cointegration approaches to further test the robustness of our conclusions. Our results suggest that there are two main long-run determinants of the RER in Ethiopia: trade openness is found to be correlated with RER depreciations, while a positive shock to the terms of trade tends to appreciate the RER. Foreign aid is not found to have a statistically significant impact, while there is only weak evidence that remittances are associated with RER appreciations. The lack of empirical support for the ‘Dutch disease’ hypothesis suggests that Ethiopia has been able to effectively manage large capital inflows, thus avoiding major episodes of macroeconomic instability. We believe that most African countries will therefore be able to absorb large inflows of foreign capital without damaging their external competitiveness. 相似文献

This article analyses the links between international financial and trade integration and financial development in sub-Saharan African (SSA) countries. It is based on a panel data set using methods that tackle slope heterogeneity, cross-sectional dependence and nonstationarity. The results do not point to a general direct robust link between trade and financial integration and financial development in SSA, once we control for other factors such as GDP per capita and inflation. The findings may be due to a number of factors including distortions in domestic financial markets, relatively weak institutions and/or poor financial sector supervision. We find some indication that financial integration is more important for financial development in countries with better institutional quality. Stronger scores in some measures of the quality of banking regulation and supervision are also linked to a positive association between integration and financial development in some of our results. Thus, African policy-makers should be cautious about expectations regarding immediate gains for financial development from greater international integration. Such gains are more likely to occur slowly and through indirect channels. 相似文献
