Regarding the effect of product variety on purchase probability, there exist findings which demonstrate a positive effect
of variety for small assortments and a negative effect of variety for large assortments. Despite these results, little evidence
exists about the causal mechanism of this effect. We conduct a field study among German consumer electronics customers to
investigate the previously proposed constructs of anticipated product utility, anticipated regret and evaluation costs. The
results suggest that anticipated regret and evaluation costs play a powerful role in explaining the negative link between
variety and purchase probability for high variety assortments. Anticipated product utility on the other hand serves to explain
part of the positive causality for low variety assortments. The results obtained give rise to recommendations for the planning
of assortments.

Objectives: Male sex work (i.e., escorting) is a stigmatized profession, and men in the sex industry may hide their involvement to avoid negative social consequences. There is limited research comparing men who are out about being an escort to their friends and/or family to those who are out to neither friends nor family. Methods: Data were taken from a 2013 online study of male escorts who were categorized into 3 groups based on outness patterns — friends only (48.9%, n = 193), friends and family (26.6%, n = 105), or neither friends nor family (23.5%, n = 93) — and they were compared on demographic and behavioral variables. Results: We hypothesized that men out to neither friends nor family would perform poorer across indicators of health and well-being due to the lack of social support that can come from friends and family. However, with the exception of reporting lower satisfaction and pay from their last male client, this hypothesis was unsupported. Outness patterns were largely unassociated with social and sexual behaviors with the last male client, and the majority eschewed condomless anal sex with their last male client, suggesting escorts — regardless of how out they are to friends and family — could navigate safer-sex behaviors with their clients. Outness was associated with substance use (<12 months) and substance use with their last male client — men out to friends and family were, for the most part, the most likely to have used substances. Men out to friends and family were significantly more likely than others to have been escorting for more than 5 years and to be escorting full-time. Conclusions: Interventions for escorts that address substance use and sexual risk behaviors and incorporate supportive friend and family social networks may be an important area for future research. 相似文献

Methodological troubles as problems and phenomena: ethnomethodology and the question of ‘method’ in the social sciences 下载免费PDF全文

Across the disciplinary frontiers of the social sciences, studies by social scientists treating their own investigative practices as sites of empirical inquiry have proliferated. Most of these studies have been retrospective, historical, after‐the‐fact reconstructions of social scientific studies mixing interview data with the (predominantly textual) traces that investigations leave behind. Observational studies of in situ work in social science research are, however, relatively scarce. Ethnomethodology was an early and prominent attempt to treat social science methodology as a topic for sociological investigations and, in this paper, we draw out what we see as its distinctive contribution: namely, a focus on troubles as features of the in situ, practical accomplishment of method, in particular, the way that research outcomes are shaped by the local practices of investigators in response to the troubles they encounter along the way. Based on two case studies, we distinguish methodological troubles as problems and methodological troubles as phenomena to be studied, and suggest the latter orientation provides an alternate starting point for addressing social scientists' investigative practices. 相似文献

The main purpose of this article is to introduce the E-Bayesian approach to gain flexibility in the reliability-availability system estimation. This approach will be used in series systems, parallel systems, and k-out-of-m systems, based on exponential distribution under squared error loss function, when time is continuous. We use three prior distributions to investigate its impact on the E-Bayesian approach, those prior distributions cover a big spectrum of possibilities. We show in real examples and also by simulations, how the procedure behaves. In the simulation study also we explore the impact on this estimation approach, when the number of components of the system increases. 相似文献

Common ratio effects should be ruled out if subjects’ preferences satisfy compound independence, reduction of compound lotteries, and coalescing. In other words, at least one of these axioms should be violated in order to generate a common ratio effect. Relying on a simple experiment, we investigate which failure of these axioms is concomitant with the empirical observation of common ratio effects. We observe that compound independence and reduction of compound lotteries hold, whereas coalescing is systematically violated. This result provides support for theories which explain the common ratio effect by violations of coalescing (i.e., configural weight theory) instead of violations of compound independence (i.e., rank-dependent utility or cumulative prospect theory). 相似文献

An excellent reputation for product innovation (RPI) is an intangible asset for any company and promises a sustainable competitive advantage. This study empirically analyzes the spillover effects of a high component supplier's RPI to the offering of the original equipment manufacturer (OEM). The results show that there are positive effects to be gained from the innovativeness of a component supplier, which increases the perceived performance of the final offering containing the supplier's product. In addition, the study demonstrates that such a strategic partnership between a component supplier and an OEM has the potential to influence the purchase intention of the final consumer in a positive manner, thereby creating value for both parties. Contributions are made to a better understanding of strategic options for such a partnership and to an on-going discussion on RPI and the importance of intangible attributes in innovation management. 相似文献

Research and practice have mostly focused on the “bright side” of social media, aiming to understand and help in leveraging the manifold opportunities afforded by this technology. However, it is increasingly observable that social media present enormous risks for individuals, communities, firms, and even for society as a whole. Examples for this “dark side” of social media include cyberbullying, addictive use, trolling, online witch hunts, fake news, and privacy abuse. In this article, we aim to illustrate the multidimensionality of the dark side of social media and describe the related various undesirable outcomes. To do this, we adapt the established social media honeycomb framework to explain the dark side implications of each of the seven functional building blocks: conversations, sharing, presence, relationships, reputation, groups, and identity. On the basis of these reflections, we present a number of avenues for future research, so as to facilitate a better understanding and use of social media. 相似文献
