不同线上销售模式的产品定价策略研究

现售和预售是线上销售的主要模式。考虑不同模式下消费者对产品估值的差异，分析现售、预售和混合销售（同时开展现售和预售）三种模式下消费者购买决策过程，构建Stackelberg博弈和Nash均衡模型，得到三种模式的产品均衡定价及需求，并探讨开展不同销售模式对应的消费者估值差异阈值以及不同主导结构对供应链企业绩效的影响。结果表明：任意主导结构下，销售模式只会影响现售产品价格，对预售产品定价没有影响；任意销售模式下，制造商主导结构的产品定价和批发价更高，但产品销售量较低；消费者延迟收货敏感度增强使预售模式的供应链成员企业的利润降低，但混合销售模式可以有效防止由此引起的损失，且制造商主导可以同时实现供应链成员企业的利益最大化。     

Re-approaching interview data through qualitative secondary analysis: interviews with internet gamblers

ABSTRACT

This paper addresses two interrelated questions concerning what interview data are and how researchers might use them. The first considers the value of a shift from a predominant or exclusive focus upon how data are constructed and produced at interview, and towards how such data might be apprehended through different forms of engagement. The second question relates to how and what qualitative secondary analysis (QSA) might be used to tell about the social world. In exploring this, we advance a critique of the divide between primary and secondary analysis, recasting the debate in terms of different degrees and qualities of ‘proximity’ and ‘distance’ from the formative contexts of data generation, and the distinctive analytical affordances that relate to these. Using QSA of interview data from a study of problem internet gambling as an empirical crucible, we consider the kinds of participation that interviewees develop through reciprocal engagement with interviewers. We illustrate how participants reflexively negotiate the affordances and limits to the narratives through which they frame and recount their experiences. Finally, we show how interview data can be used both to speak of the temporal, relational, spatial, epistemic contexts of their production, and also to contexts and questions beyond these.     

EXPOsing Men's Gender Role Attitudes as Porn Superfans

Much contemporary debate about pornography centers on its role in portraying and perpetuating gender inequality. This article compares traditional gendered attitudes between cisgender men attending the Adult Entertainment Expo (n = 294) and a random sample of male respondents from the 2016 General Social Survey (GSS), a U.S. representative survey of general attitudes and beliefs collected every two years (n = 863). Our survey borrowed questions from the GSS to measure attitudes about gender equality across four dimensions: (1) working mothers, (2) women in politics, (3) traditional gender roles in the family, and (4) affirmative action for women in the workplace. Through bivariate analyses, we found that “porn superfans” are no more sexist or misogynistic than the general U.S. public on two of the four measures (women in politics and women in the general workplace) and held more progressive gender‐role attitudes than the general public on the other two measures. We conducted binary logistic regressions for those two measures to determine if the relationship remained significant when controlling for other factors. For one dimension, working mothers, it did (p < .001). Our results call into question some of the claims that porn consumption fosters de facto negative and hostile attitudes toward women.

网络商行为的法律规制

网络商行为是一种全新的贸易方式和商业模式。近年来,网购侵权案件在我国持续发生,并逐渐成为我国行为主体维权的一个全新领域。但我国目前尚没有明确的立法对网络商行为进行调整,法律体系中亦缺乏相关制度。对网络商行为相关法律问题进行研究,探讨现存网络商事交易行为制度的疏漏之处及其法律规范,从而有针对性地对网络商行为进行规制,净化网络交易市场,保障商行为者的合法权益,维护我国市场经济秩序的稳定。     

我国城乡居民消费函数的理论假说与实证检验

本文采用1980-2009年的我国省级面板数据检验发现,持久收入假说和生命周期假说不能完全解释我国城乡居民的消费行为,绝对收入假说和随机游走假说对我国城乡居民消费不适用,而预防性储蓄假说和流动性约束假说适用于我国城乡居民消费。

Using a Web‐Based Diary Method to Estimate Risks and Benefits from Fish Consumption

Accurate estimates of the amount and type of fish people eat are necessary to determine the health benefits and risks of consuming fish, and to assess compliance with fish consumption guidelines issued for fish affected by chemical contaminants. We developed a web‐based and mobile‐phone‐enabled diary methodology to collect detailed fish consumption information for two 16‐week periods in the summers of 2014 and 2015. We recruited study participants from two populations living in the Great Lakes region—women of childbearing age (WCBA) and urban residents who had purchased fishing licenses. In this article, we describe the methodology in detail and provide evidence related to participation rates, the representativeness of our sample over time, and both convergent validity and reliability of the data collection methods. Overall, 56% of WCBA and 50% of urban anglers provided complete data across both data collection periods. Among those who provided information at the beginning of Year 2, 97% of both audiences provided information throughout the entire 16‐week period. Those who participated throughout the two‐year period were slightly older on average (1.9–2.5 years) than other members of our original samples. We conclude that using diaries with web and smartphone technology, combined with incentives and persistent communication, has strong potential for assessing fish consumption in other areas of the country or for situations where the potential risks associated with fish consumption are substantial and the cost can be justified.     

Effect of a Web-Based Sexual Health Enhancement Program for Women with Gynecologic Cancer and Their Husbands

Objectives: This study examined the effects of a web-based sexual health enhancement program on of women with gynecologic cancer and their husbands. Methods: Twenty-one couples attended the program for 4 weeks and 22 couples were assigned to a control group. Results: The experimental group reported significant improvements in the sexual function of the women with gynecologic cancer (effect size [ES] = .75; p?p?=?.015). Conclusions: Therefore, our results can help provide interventions for patients and their husbands to identify and resolve sexual problems after gynecologic cancer treatment.
