Smallholder farmers continue to make up the largest proportion of the world's disadvantaged. Rural smallholders in the South Pacific are particularly vulnerable to climate change, underinvestment and growing competition for land and resources. Strengthening synergies between agriculture and tourism through avenues such as agritourism has been widely discussed; however, very little research has approached these concepts from a sustainability perspective. This case study of rural Ni-Vanuatu smallholders uses the Agroecology and Sustainable Rural Livelihoods Framework (ASRLF) to explore tourism's potential contribution to improved conservation and food security outcomes. Data collection combined participatory methods such as “storian sessions” with analysis of secondary data.
The findings highlight minimal current opportunities for rural Ni-Vanuatu smallholders to gain significantly from the tourism sector in Vanuatu. The shift from traditional gardening systems to cash cropping monocultures is also conflicting with tourism and conservation goals. This paper puts forward agroecological tourism as a strategy for integrating positive conservation, food security and livelihood outcomes for rural smallholders. It defines agroecological tourism as having a primary focus on the interpretation of sustainable traditional agroecosystems which exhibit cultural and heritage significance. Agroecological tourism has potential to support traditional practices, enhance the preservation of cultural knowledge and promote sustainable farming practices. 相似文献
In this study, we investigate the cross-section of option-implied tail risks in commodity markets. In contrast to findings from equity markets, left and right tail risks implied by option markets are both large. Commodity-specific variables exert the largest influence on tail risk, while there is no evidence of systematic commodity factors that are linked to tail risk. Additionally, we find strong links to the equity markets, but also comovements to macroeconomic factors. Left or right tail risks are largely independent of variance risk premiums. Finally, both left and right tail risks are priced in the cross-section of commodity futures returns. 相似文献

The recent revisions of conceptual frameworks (CFs) by the IASB and the FASB included changes to the status of prudence/conservatism, accompanied by a broader debate about the meaning and role of asymmetry in financial accounting theory (FinAT). This paper adopts a historical perspective to identify possible sources of the current controversies by examining how the discourse on asymmetry has developed over time. For this purpose, we trace the conceptualization of asymmetry in FinAT building from the 19th century until 2018, covering contributions to the US FinAT literature and the conceptual reasoning of standard setters (and their constituents) in the United States and at the international level. We identify four distinct constructs of asymmetry (ultra-, specified, discretionary, and neutral asymmetry) developed in FinAT under the headings of “conservatism” and/or “prudence.” Our analysis reveals that the respective historical circumstances strongly influenced which notion and role of asymmetry were commonly accepted in FinAT, while the arguments underlying the debates were going in circles and were characterized by an increasing level of abstraction over time. We conclude that the controversy about asymmetry is partially due to conceptual ambiguity but also due to different assumptions about the objective of financial reporting and attributes of the preparer, which are indicative of two conflicting paradigms shaping the FinAT discourse on asymmetry. Our findings point to gaps and limitations in the deductive CFs currently employed by the IASB and FASB. Our study highlights future research potential regarding the construction of the preparer in standard setting and analyses of the ways in which deductive CFs (fail to) translate into consistent standards. 相似文献
Product modularization in new product development has attracted considerable interest among scholars and practitioners from diverse fields of specialization. This has resulted in cross-disciplinary diversity in the field, diverting attention from its overall intellectual structure and hindering the development of a common view and shared concepts. Extant research lacks an integrative review, transcending a focal discipline that could identify gaps and ambiguities while making recommendations to advance the field. Considering a period of 30 years (1990–2020), we generate a data set of 2988 citing publications to which we apply a co-citation analysis. Thereby, we uncover the intellectual structure of the field and find three research perspectives that represent key knowledge bases: (1) product system, (2) production system, and (3) organizational system. Delimiting the data set into four periods, we can track developments over time, where we notice an increasing disintegration of the product system perspective, which is rooted in the discipline of engineering design. Within the two other perspectives, we document extensive dynamism in terms of publications, especially in the two most recent periods, indicating an active discussion and a potential receptivity to new trends. For these periods, we also identify an emerging cluster of fundamental publications and an increasing emphasis on the concept of system architecture. Leveraging the synthesis of these results, we forge links between neighboring disciplines and recommend avenues for further research, ideally to develop a more common view. 相似文献
Entrepreneurial ecosystems play a key role in the development of startups not only by providing support—such as flexible office space and access to skilled employees, mentors, and investors—but moreover by promoting concrete ideals about “good” entrepreneurship. However, we know less about the role that ecosystems play in managerial practices of startups. In our empirical analysis of management control systems (MCSs) in earliest-stage startups, we witness a strong influence of entrepreneurial ideals—above all, the Lean Startup philosophy—on the MCSs analyzed. Building on cross-sectional field study data resulting from a comprehensive field-immersion strategy and 50 interviews with key actors in an entrepreneurial ecosystem as well as with founder-managers of startups, we consider the entrepreneurial ecosystem as a collective meso-level community that mediates between macro-level institutional pressures and micro-level practices of startups. We show how this community, through a variety of what we term amplifying mechanisms, actively deinstitutionalizes a legacy entrepreneurial philosophy epitomized by the business plan concept. At the same time, the community propagates the Lean Startup philosophy so that this alternative has become the dominant institutional philosophy in the studied ecosystem and its startups. Due to the amplifying mechanisms exerted by the meso level, startups use MCSs that play a crucial role in the rapid experimentation and learning process toward finding a scalable business model that is characteristic of the Lean Startup philosophy. We highlight that this philosophy of scientific experimentation has, to a significant degree, transformed intuitive entrepreneurial processes into a set of transactions that can be steered and accelerated by MCSs. 相似文献
