Driven by the proliferation of augmented reality (AR) technologies, many firms are pursuing a strategy of service augmentation to enhance customers’ online service experiences. Drawing on situated cognition theory, the authors show that AR-based service augmentation enhances customer value perceptions by simultaneously providing simulated physical control and environmental embedding. The resulting authentic situated experience, manifested in a feeling of spatial presence, functions as a mediator and also predicts customer decision comfort. Furthermore, the effect of spatial presence on utilitarian value perceptions is greater for customers who are disposed toward verbal rather than visual information processing, and the positive effect on decision comfort is attenuated by customers’ privacy concerns.  相似文献

Ecotourism in private reserves combines the establishment of protected areas with an incentive mechanism to conserve biodiversity. Brazil's private reserve system is well-established but little is known about its links to tourism. This study puts the global private protected area into context and quantifies the extent to which ecotourism has been adopted as a sustainable land-use practice on private reserves in Brazil. Our findings demonstrate that small reserves do contribute to conservation and are used for ecotourism. The belief that large reserves are necessary for ecotourism and conservation is challenged. Only 4% (n = 45) of the 1182 reserves are engaged in ecotourism, mainly those within the Atlantic Forest biome and these are generally small in size (<50 ha). Reserves provide modest to basic accommodation as well as education and economic opportunities that include adjacent communities. Hiking and bird watching are the most popular activities but many reserves are threatened by poaching and invasive species. The low adoption of ecotourism appears due to a combination of factors, including lack of landowner interest, constraints imposed by regulations, logistics and anthropogenic threats. Nonetheless, there is potential to expand ecotourism within private reserves as 143 further private reserves are located near those already engaged in ecotourism.  相似文献

This paper starts from the stylized fact that firm size and exporting tends to be positively related. Using large sets of establishment panel data for three different industries from official statistics, evidence is presented that the familiar picture of an export/sales ratio that increases (at a decreasing rate) with firm size vanishes if unobserved firm heterogeneity is controlled for in a fixed-effects fractional logit regression model. This finding is well in line with the fact that many small firms are “hidden export champions.” JEL no. F10, D21, L60  相似文献

Abstract The pessimistic flavour of the Human Development Reports appears to be in contradiction with their own numbers as developing countries fare comparatively better in human development than in per capita GDP terms. This paper attempts to bridge this gap by providing a new, ‘improved’ human development index (IHDI), informed by welfare economics. The IHDI is presented here alongside the United Nations Development Programme's (UNDP) HDI for the world and its main regions since the late 19th century. Social dimensions in the IHDI are derived, following Kakwani (Journal of Development Economics 41 (1993), pp. 307–336), with a convex achievement function, whereas a geometric average is employed to combine its dimensions (longevity, knowledge and income). Thus, the IHDI does not conceal the gap between rich and poor countries and casts a much less optimistic view than the conventional UNDP index, while it fits with the UNDP concern for international differences. The paper's findings highlight main weaknesses in human development dimensions of present‐day developing countries.  相似文献

Past research on B2C relationships has typically focused on unidimensional constructs of satisfaction, trust, and commitment, ignoring underlying psychological dimensions. Although some studies have examined cognitive and affective dimensions of these relational constructs, dual sequential effects in relationship formation have not been investigated. This study proposes and finds (in the context of online group chat) that parallel cognitive and affective sequences of relationship formation take place, thus expanding scholarly understanding of underlying psychological processes and offering marketing practitioners two different ways to build relationships with consumers. The proposed dual‐sequence relational framework further advances theory by shedding light on counterintuitive findings in past research. The study also supports the proposed moderating effects of employee communication style, such that sequential effects of cognitive (affective) relational constructs are stronger with a task‐oriented (socially oriented) employee, thus offering insights to practitioners in hiring and training employees to match specific organizational goals for building relationships with consumers. © 2009 Wiley Periodicals, Inc.  相似文献

Previous studies already established the idea of a partnership in which HR professionals and line managers share an organisation’s HRM responsibility. Yet, this relationship is often plagued by conflicts and other obstacles. As such, a perceptual discrepancy is likely to exist between both parties on the degree of HR devolution, which may eventually lead to bad performance. Using survey data, we empirically analyse which factors may explain a perceptual discrepancy between HR professionals and line managers on the latter group’s role in HRM. Results show that the HR-line discrepancy on the degree of HR devolution is rooted in differences in perception on several other factors, including organisational support, (personnel) red tape, the line’s individual capacity and age. Overall, though, it is a matter of understanding both HR’s expectations and the line’s experiences in all aspects of their partnership.  相似文献

We examine the relative importance of country, industry, world market and currency risk factors for international stock returns. Our approach focuses on testing the mean-variance efficiency of the various factor portfolios. An unconditional analysis does not show significant differences between country, industry and world portfolios, nor any role for currency risk factors. However, when we allow expected returns, volatilities and correlations to vary over time, we find that equity returns are mainly driven by global industry and currency risk factors. We propose a novel test to evaluate the relative benefits of alternative investment strategies and find that including currencies is critical to take full advantage of the diversification benefits afforded by international markets.  相似文献

The aim of this paper is to test whether the European Commission activities generate a heterogeneity effect on the merging parties. A sample of 74 firms involved in 45 contested merger and acquisition operations during the years 1990 to 1999 is used. The methodology is based on the GARCH framework. The main result is that, globally, the DGC interventions seem not to reduce significantly the heterogeneity among investors, except for the operations where it takes strong decisions like prohibition. In these last cases, the signal coming from the DGC encompasses valuable information and is well understood by market participants.  相似文献
