Real estate investment portfolios of financial institutions have seen dramatic changes over the last three decades or more. Historically such property investment decisions have been seen within a portfolio diversification paradigm that has sought to balance risk and return. This paper considers the role of the supply of assets in the determining and constraining the UK institutional portfolio. The supply of real estate assets not only expands during property booms but has also been transformed by a long term urban development cycle as cities adapt to cars and the ICT revolution that has brought new property forms. The research examines long term trends in investment change by disaggregating into ten property forms rather than the usual three land use sectors. It then assesses to what extent investment patterns can be explained in terms of portfolio theory, short term net returns of individual sectors or driven by the supply of real estate assets. It concludes that the supply of real assets is an overlooked explanation. 相似文献

Farmers in the Vietnamese Mekong Delta face a wide range of climate-related and hydrological factors which threaten rice production. Smallholder farmers must adapt to climate change to sustain rice production as their central and most important livelihood activity. A sample was stratified across agro-ecological areas in the Delta affected by flooding, alluvial soils, acid sulphate soils, and saline water intrusion and by derived farmer typologies. A rural livelihoods approach was used in focus group discussions and in-depth interviews to identify and enumerate enabling and constraining adaptation factors. Smallholders experienced diverse natural hazards such as floods, abnormal rains, high temperatures, water scarcity, and salinity intrusion specific to the agro-ecological areas. Adaptation was constrained by labour shortages, water quality, topography, access to combine harvesters, transportation infrastructure, dryers and household savings. Adaptation was enabled by farming techniques and experience, cooperative groups, water quantity, access to information, and ability to purchase agro-chemicals through credit. Small farmers (< 1?ha) were more constrained than large farmers (> 1?ha) who had an expanded livelihood asset base. A range of policy implications are discussed, but adaptation is not just about technological fixes but requires overall improvements in a range of human, social and financial components. 相似文献

There is a recognized need for the participation of local communities in designing and implementing agricultural interventions for the sustainable intensification in smallholder systems. This study examines the perspectives of local community leaders towards the widely promoted, but not widely adopted, practice of Conservation Agriculture (CA) in African smallholder systems. Perceptions from 47 community leaders (both from traditional local authorities and farmer organizations) across six African countries are documented regarding how CA matches the wants, needs and capabilities of farmers in their communities. While community leaders generally perceived CA as potentially beneficial, they also indicated that CA is not currently perceived as feasible within their communities and hence has limited relevance. Three key themes were identified that limit both CA use and sustainable intensification more generally: [1] a perceived reluctance of farmers to engage with the community platform as part of a higher input, market-oriented production system; [2] informational constraints due to non-functional exchange mechanisms; and [3] a lack of local adaptation of CA underscored by the persistence of top-down, linear research and extension approaches. Through greater understanding of local perspectives, a clearer picture emerges of the need for greater participatory engagement and local adaptation if sustainable intensification of African smallholder agricultural systems is to be achieved. 相似文献

Looking inside the spiky bits: a critical review and conceptualisation of entrepreneurial ecosystems
The concept of entrepreneurial ecosystems has quickly established itself as one of the latest ‘fads’ in entrepreneurship research. At face value, this kind of systemic approach to entrepreneurship offers a new and distinctive path for scholars and policy makers to help understand and foster growth-oriented entrepreneurship. However, its lack of specification and conceptual limitations has undoubtedly hindered our understanding of these complex organisms. Indeed, the rapid adoption of the concept has tended to overlook the heterogeneous nature of ecosystems. This paper provides a critical review and conceptualisation of the ecosystems concept: it unpacks the dynamics of the concept; outlines its theoretical limitations; measurement approaches and use in policy-making. It sets out a preliminary taxonomy of different archetypal ecosystems. The paper concludes that entrepreneurial ecosystems are a highly variegated, multi-actor and multi-scalar phenomenon, requiring bespoke policy interventions. 相似文献

This study provides further empirical investigation, in the context of giant Japanese banks, of the recent claim by Pulley and Braunstein (1992, A composite cost function for multiproduct firms with an application to economies of scope in banking, Review of Economics and Statistics 74, 221–230), that their new composite model for the multiproduct cost function has important advantages over the separable quadratic, generalized translog and standard translog models. In addition to assessing the composite model's relative ability in measuring global scope and scale economies, the study also extends the P-B analysis to assess measurement of product-specific scope and scale economies, pairwise cost complementarities between outputs, changes in the marginal costs of outputs and technological change. The results appear to confirm P-B's chain. The persistent finding of scale economies for large Japanese banks is also investigated and confirmed. 相似文献

Preparing qualified graduates for the tourism and hospitality industry who will stay and achieve promotional success is paramount. The objectives of this research project were to determine promotional advancement expectations and strategies to improve promotional opportunities. Two separate questionnaires, with both open and close-ended questions, were sent to upper classmen/women in hospitality and tourism programs and alumni of the same programs. In total, 717 (409 students and 308 alumni) completed the questionnaires. Chi-square tests were run to determine differences between student and alumni responses. To assist in analysis of open-ended responses, Atlas.ti was used. There was a statistically significant difference between students and alumni responses in regards to promotional expectations; students expected it to take a significantly longer time to receive a promotion to supervisor or manager than alumni. Overall, students and alumni indicated strategies such as more real-world-focused courses with hands-on experiences. 相似文献

ABSTRACTThis study investigates job location and its relationship with employee turnover intention within the casino-entertainment industry. The researchers analyzed turnover intention at the supervisor and company level from the perspective of employees who hold front-of-house or back-of-house jobs in three Nevada casinos and their corporate office. The results of this research fill existing gaps in the academic literature related to turnover intention and provide beneficial implications for industry and academic practitioners. Organizations within the casino-entertainment industry may develop strategies related to the management of human capital that could provide fiscal and operational benefits. 相似文献

Location, like every other element of the retailing mix, is in a constant state of change. Yet academic conceptualizations of retailing location have changed little in the last thirty years. Indeed, this conceptual stasis stands in marked contrast to the dramatic methodological developments that have recently taken place. This paper examines the traditional, hierarchical model of urban retail location and presents an alternative, post-hierarchical perspective. A distinction is drawn between the shape or form of retailing locations and the functions found therein. A classification of urban retail locations is also proposed and a synthesis with the hierarchical model recommended. 相似文献
