Joint space multidimensional scaling maps are often utilized for positioning analyses and are estimated on survey samples
of consumer preferences, choices, considerations, or intentions so as to provide a concise spatial depiction of the competitive
landscape including relevant dimensions or attributes, competing brands, and consumers in the same joint space representation.
Care has to be given concerning the underlying scale properties of such survey data so as not to distort the resulting joint
space positioning map. We present a new joint space multidimensional scaling procedure for positioning analyses for displaying
the structure in such survey data when such common ordered successive category measurement scales such as Likert, Edwards,
semantic differential, etc., are employed. We present the technical details of this stochastic ordered preference multidimensional
scaling vector model as well as the maximum likelihood estimation-based algorithm devised for parameter estimation. Favorable
comparisons are made with several existent multidimensional scaling methods in representing the internal structure for such
data in marketing positioning studies. An actual commercial positioning application concerning large sports utility vehicles
consideration to buy judgments is presented with predictive validation comparisons with other multidimensional scaling joint
space procedures. 相似文献

The living standards in Korea during the colonial period (1910–1945) have been debated for a long time. We explored this problem using the height of the Hangryu deceased, a dead person who did not have any acquaintances to claim the body. We found that the height of male Hangryu deceased, ages 25 to 30, increased by 2.2 cm during the colonial period. This result is consistent with recent quantitative studies measuring income levels or demographic information. However, questions such as when this growth in height started and what initiated this pattern need further investigation. 相似文献

Agriculture–nutrition linkages (ANLs) have been increasingly investigated in the literature. However, nutritional returns and costs of household agricultural production practices (APPs) in semisubsistence settings are poorly understood. We fill these knowledge gaps using pooled cross-section data sets in Tajikistan, where semisubsistence farming and undernutrition coexist despite relatively good agricultural infrastructure and education systems. Agricultural diversification, yield enhancement, production expansion are positively associated with various nutritional outcomes, particularly in areas with poor food market access. Decomposition exercises suggest that nutritional returns and costs of these APPs vary across households, and the adoption of APPs is driven by the expected nutritional returns. In Tajikistan, improving nutrition through household ANLs requires growing the smallholder agricultural sector in multiple dimensions, including diversification, intensification, and expansion, while also understanding better the pathways of ANLs and addressing bottlenecks at appropriate stages of such pathways. 相似文献

While the concept of corporate social responsibility (CSR) has gained much attention and is currently practiced by many companies, it has yet to be empirically examined in the context of hotels and casinos, especially in regard to the potential effects of CSR on firm value and performance. As the findings on the relationship between CSR and financial performance have been inconclusive and this relationship has been found to differ among industries, this study examines the relationship between CSR and firm value and profitability for hotels and casinos. Results of the Durbin–Wu–Hausman (DWH) test and a subsequent two-stage least square (2SLS) method show that hotel companies’ CSR has a simultaneous and positive relationship with financial performance. For casino companies, however, results show that CSR has no simultaneous or particular effect on financial performance. Findings suggest that hotel companies can confidently and strategically increase CSR investment to enhance both short-term (profitability) and long-term performance (firm value). Casino companies need to carefully examine the effects of CSR on financial performance, when making CSR-related decisions. 相似文献

This paper examines the international trade of a variety of genetically modified (GM) food products over a 27-year period (1984–2011) with data from the United Nations using the tools of social network analysis. The results indicate that each of the different crops have a distinctive pattern of trade that has changed over time due to a number of different factors. Also, trade in agricultural commodities became more diversified over time, dominated less by the United States and other nations central in the trade networks and trade in the individual GM crops was stable over time. Countries maintained their trading partners for specific crops, despite the adoption of the genetically modified varieties. The economic implications of these results are discussed for specific countries. 相似文献

The boundary conditions of supply chain integration (SCI) have been widely studied in order to find out when SCI is applicable and effective. However, prior studies have mainly focused on external contextual factors, such as supply complexity, environmental uncertainty and country-level infrastructure. This study contributes to the SCI literature by examining the contingency effects of internal production systems on the relationship between supplier integration, customer integration and operational performance. Based on organizational information processing theory, we provide evidence to show that the impact of supplier and customer integration on operational performance varies across production systems, such as one-of-a-kind production, batch production and mass production systems. The empirical results also reveal how supplier and customer integration can be matched with different configurations of production systems in order to achieve the desired quality, flexibility, delivery or cost performance. 相似文献

This study explores residents’ attitudes toward future tourism development based on their community well-being (CWB) and community attachment. Focusing on the case of Gamcheon Culture Village in Busan, South Korea, which was developed during an urban regeneration project in 2009, an exploratory factor analysis was conducted. The main findings of this study are: (1) CWB is supported by five variables including income effects, social participation, safety service, infrastructure service, and environmental effect; (2) not only does CWB influence community attachment but attachment also effects residents’ attitudes; and (3) the most effective variable of CWB is income effect, and safety service for community attachment. These results can help to provide effective strategies to encourage residents to have positive attitudes about further tourism development in a community-based tourism destination. 相似文献

Do stronger intellectual property rights induce more agricultural trade?: a dynamic panel data model applied to seed trade 总被引:1,自引:0,他引:1
Do stronger intellectual property rights (IPRs) induce more agricultural trade? Based on panel data for 60 countries during 1990–2000 and using a dynamic panel data model, this article assesses whether and how national differences in IPRs affect the trade flow of planting seeds imports from the United States. The empirical results show that whether or not a country adheres to IPRs agreements has no discernible impact on planting seeds that are imported from the United States, implying that the strengthening of IPRs seems not to induce more agricultural trade. This result sheds some light on the debate in the theoretical literature on the importance of IPRs and trade. 相似文献
