融合内容分析和关联分析的短生命周期体验品需求特征模式挖掘方法研究

挖掘特定产品的需求模式无法从整体掌握该类产品的市场特征；短生命周期体验品因缺乏历史销售数据，并且销售总量波动性极大，尤其需要从整体掌握销售总量与产品属性间关系的需求特征规律，但又难以挖掘，亟待提出适用于该类产品的需求特征模式挖掘方法。基于按销售总量分区后各区的需求特征的规律性，提出了一种按销售总量分区、以已有产品介绍集和销售总量为源信息、适用于新产品开发前使用、融合内容分析和关联分析的短生命周期体验品需求特征模式挖掘方法。该方法包括基于内容分析法的产品属性挖掘方法和基于关联分析的产品属性关系模式挖掘方法。前者可以得到较全面的产品属性；后者能够构建不同销售总量区间内产品集的属性关系模式，得到各区间的产品属性关系网，获得高销售总量区间具备，但中、低区间不具备的属性关系模式，从而获得需求特征模式。通过不断更新产品介绍集和销售总量并迭代挖掘，该方法能够动态挖掘需求特征模式。最后利用2013至2016年国产犯罪和爱情类电影数据验证了该方法的可行性，并得到了这两类电影的产品属性及近年的需求特征模式，可用于指导这两类电影的创作。

The problem of intersectionality as an approach to digital activism: the Women’s March on Washington’s attempt to unite all women

ABSTRACT

This study examined the convergence of activism and intersectionality to understand how communicators create messages about social justice issues using social media. This is particularly relevant for public relations today, as digital activism almost ubiquitously involves bringing together conflicting publics who are active and social media-savvy, meanwhile maintaining an organizational brand/mission. Using the 2017 Women’s March on Washington (WMW) as an object of study, we explored how campaign messages reflected principles of intersectionality, consensus- and dissensus-based communication, and organizational self-reflection. We conducted a thematic analysis of posts from the WMW’s social media accounts as well as media quotes by the organizational leaders to get at the leaders’ intentions in their message design. Data suggested that messages of inclusivity as well as of necessary discord were employed to enact political change for WMW’s publics. We argue that although the WMW was not wholly intersectional, particularly in determining its political agenda, the efforts toward intersectionality are notable for theory-building and reflective practice, particularly for social mediated campaigns. The study proposes a theory for digital intersectional communication to guide future research and advocacy work.     

Timing it right: Suspicious students,family bonds and becoming a woman in Quito,Ecuador

To improve access to education in Ecuador, state actors encourage parents and youth to think of girls’ emotional bonds to family as potential barriers to schooling. High schoolgirls and their mothers respond by synchronising their institutional and family responsibilities with the emotional norms of age grades such as ‘student youth’ and ‘mother’. Girls dedicated to embodying national progress find themselves trying to delay strong emotional commitments to family until after they have completed their schooling. Examining their construction as emotional suspects reveals the stakes of age expectations for female citizens in Ecuador.     

中华民族共同体建设视阈下改土归流的历程、原因及作用

明清时期中央王朝实施的改土归流，不仅彻底废除了土司的政治、经济、军事、司法等特权，将国家版图内的人事权、财政权、军事指挥权、行政管理权、文化教育权等悉数收归中央，而且也是中华民族共同体由“自在”向“自觉”过渡的关键环节。明清改土归流经历了一个长期、艰巨、复杂的过程，其中既有土司利益与王朝利益的矛盾、各地土司与辖区民众的矛盾，也有中央王朝通过改土归流以增加税收、朝廷命官与乡村民众要求改土归流等现实动因。改土归流实现了国家“大一统”的目标、凸显明清国家治理能力的进步、加快了中华民族共同体建设的速度。中华民族共同体是一个由政治共同体、经济共同体、文化共同体和社会共同体四者构成的命运共同体。改土归流的实施，不仅是推动共同体由“自在”向“自觉”迈进的关键步骤和重要举措，而且使中华民族共同体在政治、经济、文化和社会诸方面发生巨大变化。     

Feminists wrestle with testosterone: Hormones,socialization and cultural interactionism as predictors of women’s gendered selves

Sociology of gender has developed beyond a personality-centered idea of “sex-roles” to an approach that stresses interaction and social structure. At the same time, there has been a concurrent development in the psychological sex-differences and medical literatures toward including the biological bases of sex-typed behavior and gender identities. In this paper, while we conceptualize gender as a social structure, we focus only on the individual level of analysis: testing the relative strength of (maternal circulating) prenatal hormones, childhood socialization, and the power of expectations attached to adult social roles (cultural interactionist) as explanations for women’s self-reported feminine and masculine selves. Our findings are complex, and support some importance of each theory. Prenatal hormones, childhood socialization, and cultural interactionism were all influential factors for gendered selves. While cultural expectations predicted only feminine selves, prenatal hormones were more robust predictors of masculine sense of self. While personality may be a relatively stable characteristic influenced by the body and childhood socialization, our results reinforce the importance of studying how the social world responds to and reinforces gendered personality.     

储层岩石矿物成分对酸蚀裂缝导流能力的影响

储层岩石矿物成分是酸压改造效果影响因素之一。研究认为，在储层岩石矿物成分中易溶物的含量及分布方式决定了酸蚀裂缝导流能力大小，易溶蚀物的含量越多，岩石溶蚀速率越快。室内测试了不同溶蚀速率下的灰岩和白云岩的酸蚀裂缝导流能力，研究了岩石溶蚀速率、易溶蚀物含量对酸蚀裂缝导流能力的影响，对酸压工艺设计方案提出了指导性建议。研究结果表明，储层岩石溶蚀速率与酸蚀裂缝导流能力增加倍比存在抛物线关系，易溶蚀物占30%40% 时酸蚀裂缝导流能力保持较好。
