ABSTRACTThis study discusses how to apply counseling-learning (CL) principles to a particular e-learning solution for teaching a tourism-related subject via a massive open online course (MOOC). Several effective caring patterns in achieving learning-related goals and being part of a community according to the CL principles are presented and discussed using the MOOC “eTourism: Communication Perspectives” as a case study. The study underlines how the MOOC platform can act as a place for contents enjoinment and active learning. Moreover, the active role of social media for increasing the engagement of learners in the proposed activities and for developing a sense of the community is identified. In particular, Facebook and Twitter can act as places for community building and informal social interactions among learners that last beyond the completion of the course, which in turn can be a valid aid for continuing the relationships among instructors/learners and learners/learners, and for reaching new ones. 相似文献

We study the role of parties in a citizen-candidate repeated-elections model in which voters have incomplete information. We first identify a novel “party competition effect” in a setting with two opposing parties. Compared with “at large” selection of candidates, party selection makes office-holders more willing to avoid extreme ideological stands, and this benefits voters of all ideologies. We then allow for additional parties. With strategic voting, citizens benefit most when the only two parties receiving votes are more moderate. With sincere voting, even with three parties, extreme parties can thrive at the expense of a middle party; and whether most citizens prefer two or three parties varies with model parameters. 相似文献

This article analyses the exit decision in the European venture capital market, studying when to exit and how it interacts with the exit form. Using a competing risks model we study the impact on the exit decision of the characteristics of venture capital investors, of their investments and of contracting variables. Our results reveals that the hazard functions are non-monotonic for all exit forms and suggest that, in Europe, Initial Public Offering candidates take longer to be selected than trade sales. Moreover our results show that, in Europe, venture capitalists associated with financial institutions have quicker exits (stronger for trade sales), and highlight the importance of contracting variables on the exit decision. An unexpected result is that the presence on the board of directors leads to longer investment durations. 相似文献

This study explores the causes or antecedents of budget participation to understand more fully the role of participation in the workplace. The study focuses on the reasons why superiors encourage the budget participation of their subordinates and draws upon several theoretical perspectives including leadership theory, agency theory and organizational justice. To examine the issues, a survey was administered to managers and supervisors in several companies. Results of path analysis suggest that superiors encourage subordinate participation when the superior's leadership style is considerate. This implies that budget participation may mediate the relation between leadership style and work outcomes. Results also suggest that superiors encourage participation when budget goals are used in the performance evaluation of subordinates, in which case, the study argues, the superiors encourage participation because of concerns about organizational justice. This finding implies that budget participation may mediate the relation between the evaluative use of budget and those work outcomes that prior research has linked to organizational justice. The proposed relation between information asymmetry and budget participation is not supported. 相似文献

Retailer initiated food quality standards are important elements to market food and agricultural products. However, farmers’ certification proceeds at an unequal speed worldwide with some countries representing a large number of certified producers and others representing very few, if any. This study aims at analysing the adoption of two private food standards, BRC Food Technical Standard and GlobalGAP, at an aggregated cross-country level using data of 2007. Negative binomial models are applied to quantify the determinants of standards’ spread at an aggregated level. The results of the econometric analysis reveal some (potential) barriers for farms and firms in developing countries to access this type of organisational innovation. Certificates of both standards seem to be issued more likely in countries with established trade relations with Germany, the Netherlands and the United Kingdom, home countries of the standards. Furthermore, larger countries and countries with better institutional quality host more certified firms. Finally, a country’s level of economic development displays a clear non-monotonic relationship to the number of certified enterprises. Although no evidence for a general exclusion of developing countries can be found, the main implication of this paper is that third-party certification for export purposes seems to reinforce already existing trade relations, potentially hampering new entrants. 相似文献

The world faces a double crisis: the food crisis and energy crisis. The agribusiness is at the center of this societal dilemma, involving aspects from the volumes of production and productivity up to the way to produce them. Furthermore, there is a discussion about the need for establishing a trade-off between production of food and energy. A central aspect regarding the way of production is on how existing resources to be used and, especially, when its degradation occurs. These discussions indicate the need for interpretation and for proposition of solutions, under a complex perspective, for this double crisis. Accordingly, this paper proposes a framework for the interpretation of complex problems and for initiatives focused on sustainability that was applied to the context of food, energy and biofuel crisis. The theoretical background comprises two theories. The first is the complexity theory, which enabled the proposition of a system to understand the reality, distinguishing and combining the several existing realities without losing the global notion; The second is the sustainability theory, which enabled the systematization of stages for the planning of more sustainable actions to operate in that context; Lastly, it was possible to infer desirable characteristics that other theories could also be included, aiming to propose solutions that are more appropriated for this specific context. 相似文献

Using insights from institutional theory, sociology, and entrepreneurship we develop and test a model of the relationship between centralized and decentralized institutions on entrepreneurial activity. We suggest that both decentralized institutions that are socially determined as well as centralized institutions that are designed by governmental authorities are important in promoting firm foundings in the environmental context. In a sample of the U.S. solar energy sector we find that state-sponsored incentives, environmental consumption norms, and norms of family interdependence are related to new firm entry in this sector. Our findings also suggest that the efficacy of state-level policies in the sponsoring of entrepreneurial growth is dependent upon the social norms that prevail in the entrepreneur's environment. We expand entrepreneurship theory and the study of institutions and the natural environment by demonstrating the integral role that social norms play in influencing the creation of new firms and by illustrating the potential effect social norms have on the effect of policy that seeks to encourage environmentally responsible economic activity. 相似文献
