本文结合人口预测方法,从人口和经济两方面分析和预测了人口发展和消费方式转变对我国未来渔业资源的影响.通过因素分解方法,分别得到了人口总量变化和城市化水平提高对水产品消费需求的影响;通过曲线拟合的方法,分别得到农村和城镇收入水平变化对人均水产品消费的影响.并结合以上两方面的预测结果,得出2005-2020年间我国水产品消费总量的需求变化.根据预测分析,对我国渔业资源的可持续性利用进行了一些理论探讨.     

Food supply chains and sustainability: evidence from specialist food producers in the Scottish/English borders

Despite an increasing interest in more sustainable forms of land management, few analyses have examined whether ‘local’ or ‘alternative’ food supply systems are sustainable in environmental, economic and social terms. Using SUSTAIN's ‘sustainable food’ criteria, this paper analyses the sustainability of a number of ‘speciality’ food supply chains operated by small rural enterprises in the Scottish/English borders. Results indicate that, in the main, the case study businesses are not particularly sustainable; instead, driven by a strong economic imperative, they often have to ‘dip’ into various ‘links’ associated with more conventional (commodity-based) food supply chains. The paper concludes by warning against the tendency to conflate terms such as ‘local’, ‘alternative’, ‘speciality’ and ‘sustainable’.     

Adaptation and change in Queensland’s rangelands: Cell grazing as an emerging ideology of pastoral-ecology

Does the current global political economic framework, or more specifically, the cost–price squeeze associated with primary production, restrict the choices of Australian cattle graziers in moving to more sustainable practices? It has often been argued by primary producers and academics, alike, that current terms of trade have resulted in reduced profitability at the property level, and as such, have made it difficult for landholders to shift to practices which are environmentally sustainable. Whilst there is mounting evidence that this is case, there is also evidence that some graziers have been able to adapt to the prevailing market conditions through an ideological as well as ‘practice’ shift. Findings from qualitative research in Central Queensland, Australia, has highlighted how ‘cell grazing’ departs from the traditional or conventional aspects of grazing which can be described as productivist, to an approach closely approximating Lang and Heasman’s (2004) ‘ecologically integrated paradigm’ [Lang, T., Heasman, M., 2004. Food Wars: The Global Battle for Mouths Minds and Markets. Earthscan, London]. It is argued that cell grazing is, at present, a marginal activity that requires an ideological and cultural shift, as well as an investment in new infrastructure, however, current cell grazing activities may also demonstrate that beef grazing has the potential to be both economically and environmentally sustainable.

Event portfolio management: An emerging transdisciplinary field of theory and praxis

The phenomenon of event portfolio has gradually received acceptance and recognition as host destinations are steadily moving towards assembling multiple events across the calendar to serve multiple policy purposes. This paper reviews all the pertinent literature providing a common ground for studying event portfolios and their management exigencies. It traces the origins of the event portfolio concept and outlines its evolution to date. It thus, maps out event portfolio management as a complex emergent field, establishing its ontological base through convergence of underlying disciplines, theories and concepts. We argue that the integrative nature of event portfolio provides a malleable ground, one across and beyond its parent disciplines that shape it as a transdisciplinary field. This theoretical underpinning is indispensable for the effective treatment and sustainable development of the field.     

Drivers and consequences of sustainability committee existence? Evidence from the hospitality and tourism industry

This study's objective is twofold: (1) to investigate whether board characteristics predict the existence of a sustainability committee, and (2) to examine whether the establishment of sustainability committees stimulates sustainability reporting, external assurance, and the adoption of the Global Reporting Initiative (GRI) framework in hospitality and tourism (H&T) firms. For this purpose, the data was derived from the Thomson Reuters Eikon database for publicly traded H&T firms from 2013 to 2018. The results indicate that while board size is a significant predictor of sustainability committee establishment, female and independent directors are not. Furthermore, the H&T firms with a sustainability committee are more likely to issue a sustainability report, to get an independent assurance statement on sustainability reporting, and to follow GRI guidelines in configuring sustainability report content and structure. Overall, the results suggest important implications to help H&T firms achieve sustainable goals and to design their boards accordingly.     

Entrepreneurial index for low-income households in Malaysia

Even though development organizations provide access to working capital and enterprise development training, they often fail to improve the socio-economic condition of low-income households. One of the factors contributing to the failure of development programs is their lack of capacity to measure the entrepreneurial potentials among the low-income participants. This study focused on the development of an entrepreneurial index that measures the entrepreneurial potentials among low-income households. Adopting a cross-sectional design, a total of 403 micro-entrepreneurs were approached from the list provided by ‘Majlis Amanah Rakyat’ and ‘Majlis Agama Islam Dan Adat Istiadat’, Kelantan. This study used formative hierarchial model to determine the local and global weights for all the items used to develop the index. Further, the nomological validity revealed a positive effect of entrepreneurial index on entrepreneurial competency, enterprise performance, and enterprise sustainability.     

The impact of material and immaterial sustainability on firm performance: The moderating role of franchising strategy

CSR and sustainability engagement is growing rapidly with ever-increasing attention. Accordingly, restaurant stakeholders now demand restaurant companies to disclose relevant ESG information (i.e., materiality) to analyze risks and opportunities that ESG factors bring to firms over the long term. As established in stakeholder theory, restaurant materiality is shaped by a firm's key stakeholders and also by the industry's distinguishing factor, franchising. However, despite their importance and timeliness, materiality and franchising remain largely absent from scholarly discussion in the field of tourism and hospitality. Using a novel industry-specific materiality classification of sustainability initiatives, here we show that franchising positively moderates the impact of investing in immaterial sustainability on firm performance. The results provide early empirical validation of stakeholder theory in relation to restaurant materiality and franchising, and show the impact of allocating a firm's resources to material and immaterial sustainability issues on firm performance in the restaurant context.     

Development and validation of standard hotel corporate social responsibility (CSR) scale from the employee perspective

The prevalent trends of sustainability and responsible management have promoted corporate social responsibility (CSR) to attract considerable research and business interest. However, despite its importance, few efforts have been exerted to develop a standardized CSR scale in the hotel industry. This study aims to develop and validate a multidimensional scale of hotel CSR measurement as perceived by hotel staff who understands CSR. Results of running factor analyses generate a five-factor structure. The overall measurement model demonstrates a satisfactory level of goodness-of-fit and supports convergent validity, discriminate validity, nomological validity, and predictive validity. The legal domain received the highest mean score among the five hotel CSR domains, followed by ethical, financial/economic, environmental, and social/philanthropic domains. The value on employee attitude toward the CSR-implementing hotel, employee satisfaction with the CSR-implementing hotel, and organizational commitment toward the CSR-implementing hotel varied between front-of-house and back-of-house employees. This validated measurement scale is recommended for future studies to explore the effect of hotel CSR in various countries or regions.
