This article reflects on aligning leisure research with the local foods movement while placing the local foods movement into the larger framework of sustainability and the fields of leisure and recreation. The local foods movement has persisted during difficult economic times; growth in local foods venues and young people endeavoring to establish small-scale sustainable farms continues to flourish. Given the history of leisure research and its continued success alleviating participation barriers and constraints, the need for leisure researchers to focus on local food systems is imperative and timely. This essay highlights the notion of leisure in living through local foods and the serious leisure aspects of small-scale sustainable agriculture. This article also encourages leisure researchers to explore and assess the relationships between the local foods movement and small-scale farming as embedded in the larger framework of sustainability.  相似文献

The paper discusses the relevance of a stronger articulation between land use and water resources systems to enhance the success of the Water Framework Directive. Using article 11 of the WFD, this paper assess (i) how the Spatial Planning and Urban Development Law as well as the Portuguese Water Law converge to promote better integration of water resources into spatial planning, (ii) how their prospects are developed at the regional basis, namely through the Regional Spatial Development Plan and River Basin Management Plan, and (iii) how these are prepared to inform other planning instruments at the local level. It shows through a spatial analysis of the regional land-use plan and the river basin plan as applied over the Ria de Aveiro estuary area, the conflicts and opportunities for stronger synergies. The paper concludes with a critical analysis of the integration of the spatial planning and water resources planning systems in Portugal, and reveals new insights and challenges for more productive synergies between these systems.  相似文献

Our existing model of media, based upon a consumptive-materialist–atomistic orientation, falls short in seeking to promote mainstream awareness of systemic and integral thinking in society-at-large. This paper presents evolutionary guidance media, a new model for media arising from evolutionary perspectives including systems science, humanistic, transpersonal and integral studies designed to promote planetary consciousness and give rise to an ecological–spiritual–integral mindset. Two key elements of evolutionary guidance media are discussed: a databank containing purposeful data from nine or more dimensions of human activity, and transception, the infusion of cyberception with qualities arising from mutual causality. Specific types of transception are introduced including Gaiaception, Agoraception, and Dharmaception. Organizations and companies already in the process of creating green media, socially responsible media, and spiritual, or transformational media are vanguards of the development of conscious media.  相似文献

We adopt the view that greater party discipline induces legislators to commit to promised policies after being elected. We then develop the hypothesis that the effect of party discipline on the stringency of environmental policy is conditional on the degree of government corruption. Our empirical work suggests that greater party discipline results in more stringent environmental policies when the level of corruption is relatively low, but in weaker policies when the level of corruption is comparatively high.  相似文献

Answering the call for alternative approaches to researching project management, we explore the evaluation of project success from a subjectivist perspective. An in‐depth, longitudinal case study of information systems development in a large manufacturing company was used to investigate how various project stakeholders subjectively perceived the project outcome and what evaluation criteria they drew on in doing so. A conceptual framework is developed for understanding and analyzing evaluations of project success, both formal and informal. The framework highlights how different stakeholder perspectives influence the perceived outcome(s) of a project, and how project evaluations may differ between stakeholders and across time.  相似文献

Organizations are using Group Support Systems (GSSs) to improve the quality of group meetings. Keypad‐based GSSs are a widely used form of this technology, yet there has been little research on their use and effects. This paper reports the findings of a survey of facilitators of a particular keypad GSS. Facilitators indicate that keypad technology improves the quality of meetings for a variety of tasks in a range of group settings and cultures. The findings are in general agreement with field studies of workstation‐based systems.  相似文献

With growing popularity of mobile devices, digital marketing strategies are increasingly important for modern airports. This paper studied context-aware mobile marketing strategies in the airport retail environment. An on-site mobile marketing experiment was conducted at a partner airport to explore how preference and/or location-based mobile coupons could affect passengers’ retail behaviour. Results show that retail shopping became more efficient (less browsing time) with mobile marketing influence, but not necessarily more effective (not higher spending amount). Randomly pushed mobile marketing information is effective in keeping passengers in shops for longer but context-aware mobile marketing is more effective in increasing spending amount.  相似文献

The impact of recommendation systems (RSs) on the diversity of consumption is not transparent or well understood. Available studies, whether experimental or theoretical, show inconsistent and even opposite results, which manifests as debate in the literature. In this paper, we investigate the impact of two main recommender systems, neural collaborative filtering and deep content filtering, on sales diversity via a randomized field experiment. Our results confirm the capability of recommender engines in increasing or decreasing aggregate sales diversity. Nonetheless, they amplify homogenization and reduce individual-level consumption diversity. In conclusion, our research reconciles seemingly contradict previous findings and illustrates that the design of the RS is the decisive factor in homogenizing or diversifying product sales.  相似文献
