Food justice, food cultures and people's engagement with healthy food production and consumption are key contemporary concerns, with a growing sustainable hospitality and tourism literature. Efforts range from narrowly focused initiatives, such as promoting organic produce and fair trade, to more holistic challenges to current systems through initiatives like the slow food and locavore movements, which may represent systemic alternatives. However, little analysis is available on how cafés and restaurants might become sites for experimentation in profitable and just sustainable hospitality, and places for sustainability engagement and education. Focusing on the evolution of a sustainable café in Adelaide, South Australia, this article explores how one entrepreneurial restaurateur uses his café to engage customers and community in a collaborative conversation about sustainable development, food, hospitality and tourism, helping transform our food culture and even lifeways. Our findings indicate the value of deep local embedding as a pathway to meaningful sustainability. The study offers insights into how hospitality and tourism can contribute to dialogues on alternative consumption which may offer visionary pathways to alternative futures. It also explores the role of pioneers in sustainable business and hospitality, their drivers and their views. A forthcoming global research initiative is discussed.  相似文献

Significant oil and gas firm market value is derived from their physical reserve quantum, assets which are not recorded on their statements of financial position. This article provides empirical evidence regarding voluntary disclosure of such reserves in line with the previously unresearched UK sector with regard to its unique reporting guidelines. The study considers both the reporting of the reserve quantum and the quality of that reporting. This article seeks to inform the International Accounting Standards Board’s (IASB’s) on-going consideration of mineral resource reporting. Listed companies are considered to evidence forms of reserve disclosure with a logistical regression approach applied to measure determinants of reporting. The risk associated with mineral reporting reserves is hypothesized as the key disclosure driver whilst controlling other relevant variables. The majority of firms disclosed reserve quantities in some form but only a minority disclosed in line with recommended practice, disclosure quality being more variable between companies. The findings indicate that a voluntary disclosure approach is ineffective, partially explained by agency related behaviour. Risk, proxied by the stage of production, drives reserve disclosure showing that producer firms are more likely to disclose reserve quantum balances and of a significantly higher quality.  相似文献

Technological innovations are seen as one of the best solutions to mitigate the environmental impacts of economic activity. Yet, the innovative success of firms, especially small- and medium-sized enterprises (SMEs), in the environmental sector is dependent on the presence of appropriate external financing to support their innovative activity. In an attempt to understand the circumstances surrounding the financing of 330 UK SMEs from the environmental sector between 2007 and 2010, we investigate the relationship between different types of innovation activity and sources of external finance. We observe a clear division of labour between the three external sources of finance, namely, banks, venture capital and government in terms of the types of innovations they finance. We also identify that finance gap affects environmental SMEs with early-stage and less applied research projects. We discuss the challenges for UK environmental SMEs to engage in innovative activity and call for an increased government action in order to support innovative SMEs with early-stage projects and to instil confidence in the private investors by signalling long-term commitment.  相似文献

Transgenic crop varieties (TGVs) are being promoted as essential for improving small-scale Third World (SSTW) agriculture. Most economic research on this topic makes critical, untested assumptions, including that farmers will choose TGVs over other varieties because TGVs are economically optimal and because farmers are risk neutral profit maximizers. We tested these assumptions using data from a survey of 334 farmers in 6 communities in Cuba, Guatemala and Mexico in which farmers ranked 4 real and hypothetical maize varieties for eating and sowing. Our results did not support these assumptions. Most farmers preferred farmer varieties for sowing and especially for eating, avoiding TGVs, a preference associated with being risk averse and with non-monetary preferences. Farmers more integrated into modern agriculture were more likely to choose TGVs. These results suggest that farmers most in need of support and most important for conserving genetic diversity are least favorable toward TGVs, and that alternative ways of improving SSTW agriculture should receive more attention.  相似文献

Geoscientists are faced with a number of complexities that represent obstacles to the development of realistic simulation of deep earth processes. Realistic 4D thermo-mechanical simulation using software packages like Underworld and Gale, when combined appropriately with geoscientific expertise, can lead to novel insights into the deformation of geological structures at a wide range of time and spatial scales. The challenge for end-user geoscientists lies in applying their knowledge within the framework of the software’s input specification, including initial, internal, and boundary conditions and output visualization parameters. We have built a Graphical User Interface (GUI) to remove many of the difficulties related to editing the Extensible Markup Language (XML) encoded input files of Underworld/Gale geomodels and therefore, to greatly broaden the user base of these software packages. By helping Underworld/Gale to meet a large audience, we provide a tool to the geoscience community that helps to move from untested conceptual models to physically valid, properly scaled modelling. Furthermore, the UnderworldGUI offers a mechanism for storing and retrieving experimental models in a centralised database, thus providing the geoscience community with a means to share the outcomes of its experimental research. Further details of the UnderworldGUI are available at the web site http://www.wiki.vislab.usyd.edu.au/moinwiki/UnderworldGUI.  相似文献

A meta-analytic review of effectuation and venture performance   总被引:1,自引:0,他引:1  
Though much research in entrepreneurship makes the fundamental assumption that opportunities are found, new work is emerging which questions this core tenet. Effectuation, for example, positions the entrepreneur as co-creator of opportunities, together with committed stakeholders. In this study, we conduct a meta-analysis of the articles published in the Journal of Business Venturing, summarizing data on 9897 new ventures to connect three of the principles of effectuation positively with new venture performance. In so doing, we offer both specific insight into precisely measuring effectuation and a general method for extracting variables from prior work to measure new constructs.  相似文献

Quantitative methods for evaluating the environmental impact of products are receiving considerable attention. Software is being developed to enable analysis of many aspects of a product's life cycle—from materials' extraction, through manufacture, to use and disposal. Less attention is being paid to the qualitative aspects of products and their significance in addressing environmental concerns. Here, the argument is made for including qualitative evaluations as an important facet of product environment assessment. Such evaluations are essential if significant progress is to be made in alleviating the adverse environmental effects of products. Combined with quantitative analyses, the two approaches become mutually supportive and, ultimately, inseparable.Qualitative environmental assessments can be applied to existing products and at every stage of the design process. Their adoption within the context of professional practice will be fostered by their inclusion, formulation and discussion within design education. This paper describes the basis and nature of these qualitative judgments, and places the qualitative and quantitative in a unified context which points towards more sustainable ways of living. The use of scenarios is discussed as a tool for academic design projects in order to address the complex relationships which might otherwise seem overwhelming to the design student.  相似文献

This essay questions expertise about the future and offers an assessment of the methods used and questions addressed by planners as they determine the inputs for setting their goals. It outlines, challenges and redefines several planning methods and suggests a more generous framework through which to focus thought about the future.  相似文献
