The purpose of this study is to investigate the perceived constraints on participating in mountaineering tourism faced by women, and to empirically verify the dimensionality of those constraints. Survey responses from 314 female mountaineers were collected and four constraint dimensions were identified using confirmatory factor analysis. Three of these dimensions: ‘intra-personal’, ‘inter-personal’ and ‘structural’ constraints support earlier findings in the extant literature, both in general and in the adventure literature more specifically. The identification of a fourth dimension relating to ‘family’ constraints represents a theoretical contribution to the literature and an additional barrier to women’s participation in mountaineering tourism. In previous studies, ‘family’ constraints have typically been subsumed within ‘inter-personal’ or ‘intra-personal’ constraints, but have emerged as a distinctly separate constraint category for women in relation to this particular tourist activity. The findings also have important implications for adventure tourism management practice.  相似文献

Although numerous studies have highlighted the contributions of remanufacturing to sustainable development and the circular economy, the decision for a company to take up this strategy is riddled with uncertainties, especially when significant capital investment is involved. To improve the economic performance of a remanufacturing system in the face of uncertainties, we propose a methodological framework for flexible design of remanufacturing systems. Its application is demonstrated using a case study based on remanufacturing laptop computers for the Cambodian market. Through the case study, we show how one can explore the opportunity of setting up a remanufacturing system, study its economic feasibility and design flexible strategies to improve its economic performance in the face of uncertainties. More interestingly, we demonstrate how Monte Carlo simulation can be used to evaluate the effectiveness of different flexible design strategies in dealing with the uncertainties.

Teachers and Students worldwide often dance to the tune of tests and examinations. Assessments are powerful tools for catalyzing the achievement of educational goals, especially if done rightly. One of the tools for ‘doing it rightly’ is item analysis. The core objectives for this study, therefore, were: ascertaining the item difficulty and distractive indices of the university wide courses. A range of 112–1956 undergraduate students participated in this study. With the use of secondary data, the ex-post facto design was adopted for this project. In virtually all cases, majority of the items (ranging between 65% and 97% of the 70 items fielded in each course) did not meet psychometric standard in terms of difficulty and distractive indices and consequently needed to be moderated or deleted. Considering the importance of these courses, the need to apply item analyses when developing these tests was emphasized.  相似文献

This study examines the effect of small business loans on subsequent establishment births in U.S. counties. Using an economic growth framework and cross‐sectional empirical model, we test the hypothesis that the establishment birth rate is higher in counties where the level and annual increase in lending is greater, controlling for community‐level characteristics affecting business and economic dynamics. We also consider the long‐term effect of small business lending and focus on establishing the appropriate lag structure. The results indicate that small business lending does generally have a positive effect on the employer establishment birth rate that is strongest in nonmetropolitan (rural) counties.

This paper develops a long-range consumption planning model which, unlike conventional life-cycle theory, admits a disparity between borrowing and lending rates of interest. It is shown that, when capital markets are imperfect, optimal consumption depends not only upon an arithmetic average of the household's intertemporal income distribution, the traditional life-cycle income variable, but also upon current income and higher-order moments of that income distribution. The consumption function is estimated using the 1967–1968 CEDE budget survey of four major Colombian cities. A test is made to determine whether the assumption of perfect capital markets is acceptable for empirical approximation. The results strongly indicate that, for households in middle and lower income classes, the explanatory power of the consumption function can be raised by introducing a more flexible life- time budget constraint. The model is then estimated and used to compute the marginal consumption responses of Colombian households to transitory and permanent income changes.  相似文献

ABSTRACT

In this paper, we examine how actors within what we conceptualise as an emerging wild food alternative network are navigating through the foodscape to find alternatives to homogenous and standardised food products. Drawing on data from different research engagements with wild food consumers and producers over the last decade in Canada, we use the context of wild foods to explore how the ‘alternative’ is being articulated and negotiated. Inspired by scholarly work exploring the pedagogical promise of food, we also explore the transformational potential of the ‘alternative’ – how bringing wild foods to the table can both inspire and teach consumers about sustainability and alternative consumption practices. We conclude with directions for future marketing research on alternative food networks.  相似文献

Entrepreneurship research has paid insufficient attention to the context in which new businesses are started. Consequently, efforts to identify factors that consistently lead to entrepreneurial success have failed. This is because what works in one context will not necessarily work in another. Even worse, factors that lead to success in one context may lead to failure in another.This article addresses this problem by drawing from the concept of industry evolution to identify three broad but distinct organizing contexts—emerging, growth, and mature industries—and demonstrating how each context presents a different set of entrepreneurial challenges. An industry is defined not as a group of firms producing close substitutes, but instead, as a group of firms of the same organizational form. Industry evolution is understood therefore as the diffusion of an organizational form, with emerging, growth, and mature stages corresponding to the creation, exploitation and erosion of competitive advantage. Defining an industry in this manner makes it possible to overcome the problem of shifting industry boundaries and enables us to distinguish between entrepreneurial activities that shake up existing industries by creating new and competing organizational forms and entrepreneurial activities that replicate well-known organizational forms and drive an industry toward equilibrium. It also enables us to draw from the work of industrial organization economics, strategy, and population ecology.Entrepreneurship is defined as the creation of new organizations and is viewed as a context-dependent social process. New organizations are enacted as critical stakeholders change their behaviors in ways that allow the organization to emerge. The process is successful when the short-term existence of a new organization is no longer at risk. A typological theory of entrepreneurial success is developed by examining how the fit between context and four other critical dimensions cause successful foundings. The theory is multiplicative and probabilistic. It is multiplicative in that all dimensions need to fit for a founding to be successful. Poor fit in any one area can lead to failure. It is probabilistic in that the better the overall fit, the better the odds of success.In addition to context, the dimensions we examine are entrepreneurial networks, entrepreneurial confidence-building behaviors, the motivation of stakeholders, and organizational structures and strategies. In terms of entrepreneurial networks, we examine whether entrepreneurs have weak-tie or strongtie networks, and whether their networks are homogeneous or include subgroups that are unrelated. In terms of confidence-building behaviors, we explore the use of informal (e.g., repeated personal interaction) versus formal (e.g., contracts) mechanisms. With respect to stakeholder motivations, we ask whether stakeholders are driven by social or instrumental motivations. In terms of structure and strategy, we consider two issues. First, we explore whether the emerging organization is market or hierarchy based, and we consider the extent to which the organization is innovative versus imitative. We argue that these various dimensions come together in three logical configurations, that we label movements, bandwagons, and clones.EMERGING INDUSTRY ORGANIZING: MOVEMENTSMovements are the organizing processes through which new organizational forms are created. Pioneers of new forms of organizations have unique personal networks that enable them to see the potential of bringing the factors of production together in new combinations. They have strong ties to two or more nonoverlapping networks. To succeed, they must overcome problems associated with lack of legitimacy. Theentrepreneur is joined by highly committed stakeholders who are motivated by social factors. Belief in the venture's success is achieved through informal confidence building, such as incremental personal exchange and third-party reputation. In this manner, stakeholders develop personal familiarity with the form and make positive assessments about the entrepreneur's competence and trustworthiness. The organizing structure is market based with participant commitments being secured through flexible, cooperative agreements. The strategic emphasis is on innovation and experimentation. The belief in the importance and viability of the new organizational form serves as a loose ideology for controlling and coordinating the actions of participants.GROWTH INDUSTRY ORGANIZING: BANDWAGONSBandwagons are organizing processes that seek to exploit the potential of a newly legitimated form. The strategic challenge at this stage is to prosper newly legitimated form. The strategic challenge at this stage is to prospeamidst rapid growth and change. The successful entrepreneur has an extensive network of high status individuals that can be tapped to quickly mobilize resources within a narrow window of opportunity. Stakeholders are motivated less by social factors, than by a desire to secure the benefits of being early movers. Formal confidence-building mechanisms dominate. In an effort to achieve efficiencies, develop sources of competitive advantage, and preempt the competition, more value-chain activities are developed in house. The strategic posture remains entrepreneurial; however, more emphasis is placed on following the example of other firms.MATURE INDUSTRY ORGANIZING: CLONESClones are the organizing processes that replicate existing forms and incorporate all that has been learned about a given industry and type of business. Strong competition along with stable demand and technology make it difficult to find a source of competitive advantage in a mature industry. At this stage, the successful founder is someone with extensive industry knowledge and contacts who is capable of extracting operating efficiencies and/or identifying some underserved market segment. Expected returns are modest and stakeholders need to be motivated partly by social factors. However, the large amount of information now available about the form and the market itserves enables stakeholders to base their participation decisions on a rational assessment of expected future benefits. Given increased experience with the form, the relationships between the organization and its stakeholders are more predictable and as a consequence, subject to greater formalization. Models exist showing how to structure theserelationships, facilitating greater use of more specific contracts and guarantees. With tight margins and the need for efficiency, greater use is made of hierarchy in an attempt to manage costs. These same highly competitive conditions also make mistakes very expensive. The organization needs to draw upon the knowledge that others have learned about the form. Consequently, it adopts a more conservative strategic posture and is less likely to deviate from established practice.IMPLICATIONS FOR FUTURE RESEARCHIf we are ever to understand what leads to entrepreneurial success, we must pay more attention to the context in which organizing occurs. Our typology suggests that fundamentally different processes may be at work at different stages of industry evolution. In addition to empirically testing our theory, an opportunity exists to reexamine the existing entrepreneurship literature through a new conceptual lens, asking how our interpretation of the research would differ if context was considered explicitly. Our theory also has the potential to inform questions about the role of organizational foundings in the diffusion of competitive advantage and to examine the impact of.founding conditions on long-term strategic adaptation.  相似文献

Companies actively seek to appoint outside CEOs to their boards. Consistent with our matching theory of outside CEO board appointments, we show that such appointments have a certification benefit for the appointing firm. CEOs are more likely to join boards of large established firms that are geographically close, pursue similar financial and investment policies, and have comparable governance to their own firms. The first outside CEO director appointment has a higher stock-price reaction than the appointment of another outside director. Except for a decrease in operating performance following the appointment of an interlocked director, CEO directors do not affect the appointing firm's operating performance, decision-making, and CEO compensation.  相似文献
