The objective of this study was to conduct empirical comparisons between two models of optimal experience within an on-site whitewater kayaking setting using a modification of the Experience Sampling Method. Four concerns are examined: (1) differences in explanatory power between the four channel flow model and the Adventure Experience Paradigm, (2) convergent validity among measures used to determine conditions within these models, (3) differences among measures of perceived challenge and risk between test times of Class I-V river difficulty, and (4) differences among measures of perceived skill and competence between test times of Class I-V river difficulty. Questionnaires were administered in the Cheat River Canyon in West Virginia to 52 whitewater kayakers at eight sites of various levels of river difficulty. Data were analyzed at the experience level, rather than between subjects, using 409 experience sampling observations. Hypothesis testing, performed with statistical analyses (stepwise regression, correlations, and repeated measures ANOVA), suggested that the explanatory powers of the four channel flow model and Adventure Experience Paradigm were similar and indicated support for convergent and ecological validity of measures used to determine conditions within each of the two models. 相似文献

The case for promoting export‐oriented cash crops in Africa has generally been based on their direct potential contribution to agricultural productivity and small farmer incomes. A relatively neglected avenue of research concerns the synergistic effects that cash cropping can have on other household activities, including food production. The conventional view that cash crops compete with food crops for land and labour neglects the potential for cash crop schemes to make available inputs on credit, management training, and other resources that can contribute to food crop productivity, which might otherwise not be accessible to farmers if they did not participate in cash crop programs. This article builds on previous research by hypothesising key pathways by which cash crops may affect food crop activities and empirically measuring these effects using the case of cotton in Gokwe North District in Zimbabwe. Analysis is based on instrumental variable analysis of survey data on 430 rural households in 1996. Results indicate that—after controlling for household assets, education and locational differences—households engaging intensively in cotton production obtain higher grain yields than non‐cotton and marginal cotton producers. We also find evidence of regional spill‐over effects whereby commercialisation schemes induce second round investments in a particular area that provide benefits to all farmers in that region, regardless of whether they engage in that commercialisation scheme. The study suggests that the potential spill‐over benefits for food crops through participation in cash crop programs are important to consider in the development of strategies designed to intensify African food crop production. 相似文献

Real estate investment portfolios of financial institutions have seen dramatic changes over the last three decades or more. Historically such property investment decisions have been seen within a portfolio diversification paradigm that has sought to balance risk and return. This paper considers the role of the supply of assets in the determining and constraining the UK institutional portfolio. The supply of real estate assets not only expands during property booms but has also been transformed by a long term urban development cycle as cities adapt to cars and the ICT revolution that has brought new property forms. The research examines long term trends in investment change by disaggregating into ten property forms rather than the usual three land use sectors. It then assesses to what extent investment patterns can be explained in terms of portfolio theory, short term net returns of individual sectors or driven by the supply of real estate assets. It concludes that the supply of real assets is an overlooked explanation. 相似文献

Children with developmental disabilities participate in more solitary, sedentary, and home-based leisure activities than active physical pursuits or community-based activities. Clinical experience suggests that children with less well-recognized developmental difficulties also have compromised leisure experiences; however, this has not been fully investigated. This study engaged 20 school-age children with developmental difficulties in a community-based circus program, designed in collaboration with occupational therapists. The program included activities such as trampolining, trapeze, and acrobatics. Semi-structured interviews with children and parents explored children's leisure experiences both at circus and more broadly. Qualitative content analysis revealed that friendships, having fun, and being physically active were highly valued aspects of leisure. The coaching style and “just right” level of challenge within programs were identified as central to children's engagement and sense of competence. Participating in a supported leisure program such as circus appeared to promote children's engagement in community leisure, at least in the short term. 相似文献

In 2015, the Federal Communications Commission (FCC) imposed common carriage regulation—so-called Title II requirements—on previously unregulated broadband Internet service providers. The regime shift was premised on the FCC’s findings that such rules had demonstrably yielded economic gains. This paper evaluates the FCC’s empirical arguments and finds them uncompelling. Adjustments for inflation or general economic trends eliminate the effects cited by the FCC. Moreover, contrary to the Commission’s assessment, mobile services and broadband markets have shown notable growth in response to deregulatory events that reduce Title II requirements. 相似文献

On-line supervision exhibits in many respects properties complementary to those of established off-line safety tests. Thus, on-line methods are powerful tools for increasing the safety of chemical processes, especially in situations where unexpected hazards could occur. Known on-line supervising methods are described and their advantage and disadvantages are briefly discussed. The abilities of various on-line methods are demonstrated on a real case. 相似文献

Previous research indicates that consumers differ in their evaluation of and response to similar retail experiences. Reporting results from three studies, the current research proposes consumers’ regulatory focus intensity as one possible source of this variation. Study 1 examines how consumers’ regulatory focus intensity influences their in‐store behavioral intentions following good and bad shopping experiences. Study 2 illustrates how consumers’ regulatory focus intensity impacts their future loyalty intentions after satisfactory retail experiences. In Study 3, the researchers explore how retailers can employ regulatory framing in their communication messages to increase the future loyalty intentions of those chronically less loyal consumers. Lastly, theoretical and managerial implications as well as limitations of this research are discussed. 相似文献

Corporate bankruptcy prediction has attracted significant research attention from business academics, regulators and financial economists over the past five decades. However, much of this literature has relied on quite simplistic classifiers such as logistic regression and linear discriminant analysis (LDA). Based on a large sample of US corporate bankruptcies, we examine the predictive performance of 16 classifiers, ranging from the most restrictive classifiers (such as logit, probit and linear discriminant analysis) to more advanced techniques such as neural networks, support vector machines (SVMs) and “new age” statistical learning models including generalised boosting, AdaBoost and random forests. Consistent with the findings of Jones et al. ( 2015 ), we show that quite simple classifiers such as logit and LDA perform reasonably well in bankruptcy prediction. However, we recommend the use of “new age” classifiers in corporate bankruptcy modelling because: (1) they predict significantly better than all other classifiers on both the cross‐sectional and longitudinal test samples; (2) the models may have considerable practical appeal because they are relatively easy to estimate and implement (for instance, they require minimal researcher intervention for data preparation, variable selection and model architecture specification); and (3) while the underlying model structures can be very complex, we demonstrate that “new age” classifiers have a reasonably good level of interpretability through such metrics as relative variable importances (RVIs). 相似文献

Fundraisers play a vital role in the success of nonprofit organizations, yet relatively little is known about the experiences, motivations, and thought processes that inform their career choice and development. This exploratory, cross-comparative case study of 3 fundraisers addresses this gap in the literature by examining some formative influences on fundraisers' careers, their professional growth aspirations and opportunities, and how, if at all, they engage in personal philanthropy. Results suggest that fundraisers' aptitudes, skills, and abilities may influence their career choice more than a sense of connection to the nonprofit sector or organizational mission. Further, fundraisers seek opportunities to exercise leadership at the individual, organizational, and community levels. Additionally, their personal philanthropy and social embeddedness play integral roles in their professional development. Although not large enough for generalization, these results suggest the need to study fundraisers holistically, including their psychological development and social embeddedness over time. We argue for the need to move beyond traditional marketing and public relations perspectives to explain fundraising. Instead, future studies should adopt a service-dominant logic framing that considers fundraisers as part of a larger philanthropic ecosystem. We conclude with several questions to guide future studies toward this line of inquiry. 相似文献
