This article seeks to demonstrate and analyze the cultural and emotional work surrogate mothers collectively engage in on the largest surrogacy support website, http://www.surromomsonline.com . Surrogate mothers’ online stories and discussions frame contract surrogacy as a “labor of love.” Women often describe their surrogacy as a “journey” of shared love; they hope for a lasting relationship with the couple they carry for. This article explores how the language of love, learned and internalized through online communication with other surrogates, creates both a cultural conceptualization of surrogacy and a ground for action. Love and altruistic giving are consistent with close interpersonal rather than market relationships; surrogates hope for a long‐term friendship with their couple. Surrogacy journeys, however, not infrequently end in disappointment; surrogates feel betrayed when couples cut ties. As a result of collective learning, surrogates’ discussions increasingly articulate the position that love, even when unreciprocated, can lead to repeated giving; love is noble and ennobling. Surrogates find appreciation and support in their online surrogacy community where they agree that giving life is a moral good. This stance has contributed to a renewed enthusiasm to bear children for others. 相似文献

The current study used dyadic data to investigate the impact of relationship type and social support on the retrospective accounts of commitment trajectories of romantic relationships. Past research suggests that social support is a positive contributor to relationship stability and commitment, which may be especially true for partners in interracial relationships who face broader societal opposition than intraracial couples. Using multilevel modeling, we investigated the effects of sex, relationship type, and social support on reports of commitment. Results showed differences in trajectories of commitment based on couple type (interracial vs. intraracial) for both men and women. Social support was found to have an especially strong impact for women in interracial relationships compared with women in intraracial relationships, but there was no differential impact among men. 相似文献

The enduring COVID-19 pandemic has gradually transformed our everyday lives. This study focuses on changes in work and family arrangements, with particular focus on changes in domestic help, and examines its impact on the division of domestic labor. Using a social survey of work and the family conducted in November 2020 and May 2021, the results show that from January 2020 (pre-pandemic) to May 2021, approximately 40% of respondents experienced a reduced gender gap for housework and childcare, while a large gender gap is still observed in the absolute frequency of undertaking domestic labor. Some lifestyle changes triggered by the pandemic, such as an increase in the use of takeaways or delivery meals, and the expansion of working from home, are found to be able to contribute a shift toward more equal sharing of domestic labor. However, the fact that the access to such lifestyle changes is more common among those with a relatively high income or high educational background suggests that the lifestyle changes imposed by the pandemic may exacerbate class disparities in the gender gap in domestic labor. Furthermore, the results show that decreased kinship support results in a greater childcare burden being placed on women. 相似文献

People differ in their comfort with tampering with the natural world. Although some see altering nature as a sign of human progress, others see it as dangerous or hubristic. Across four studies, we investigate discomfort with tampering with the natural world. To do so, we develop the Aversion to Tampering with Nature (ATN) Scale, a short scale that is the first to directly measure this discomfort. We identify six activities that people believe tamper with nature (geoengineering, genetically modified organisms, pesticides, cloning, gene therapy, and nanoparticles) and show that ATN scores are associated with opposition to these activities. Furthermore, the ATN Scale predicts actual behavior: donations to an anti-tampering cause. We demonstrate that ATN is related to previously identified constructs including trust in technology, naturalness bias, purity values, disgust sensitivity, aversion to playing God, and environmental beliefs and values. By illuminating who is concerned about tampering with nature and what predicts these beliefs, the ATN Scale provides opportunities to better understand public opposition to technological innovations, consumer preferences for “natural” products, and strategies for science communication. 相似文献

研究群知识的形式模型有助于澄清抽象的哲学概念以及概念之间的关系。然而,目前群知识的形式化的处理方法和哲学所讨论的群知识是相脱离的。对群知识的形式化的定义可称为集体知识,是关于公共问题的分布知识以及公共知识和全分布知识之间的桥梁。所有的知识都是基于对主体的不同概念的区分而获得的。为了对认知群和集体知识进行模型,需要引入新的克里普模型,即认知群模型。定义一个好的群知识有助于对基于群知识的更高层次的哲学讨论。 相似文献

文章选取初次分配工资分配率、城镇居民基尼系数、各收入阶层旅游消费占比作为分析指标,经分析研究所得结论为:低、中收入阶层旅游消费占比与分配率负相关,分配率所代表的初次收入分配总量性影响对中收入阶层旅游消费影响较大,中、高收入阶层旅游消费占比都与城镇居民基尼系数正相关,其中城镇居民基尼系数代表的初次收入分配结构性影响对高收入阶层旅游消费影响较大;并针对各阶层的特殊性对各收入阶层旅游消费发展提出相应政策建议. 相似文献

When people need help, what is the process through which they decide whom in their network to turn to? Research on social support has described a process that is deliberative in nature: people determine their needs, assess who in their network has the needed attributes—such as skill, trustworthiness, intimacy, and accessibility—and then activate that tie. Nevertheless, research in behavioral economics and other fields has shown that people make many decisions not deliberatively but intuitively. We examine this possibility in the context of social support by focusing on one factor: accessibility. Although researchers have argued that people weigh the accessibility of potential helpers as they do any other attribute, accessibility may be not only an attribute of the helper but also a condition of the situation. We develop a framework to make this question tractable for survey research and evaluate competing hypotheses using original data on an analytically strategic sample of ∼2000 college students, probing concrete instances of social support. We identify and document not one but three decision processes, reflective, incidental, and spontaneous activation, which differ in the extent to which actors had deliberated on whether to seek help and on whom to approach before activating the tie. We find that while the process was reflective (consistent with existing theory) when skill or trustworthiness played a role, it was significantly less so (consistent with the alternative) when accessibility did. Findings suggest that actors decide whom in their network to mobilize through at least three systematically different processes, two of which are consistent less with either active “mobilization” or explicit “help seeking” than with responsiveness to opportunity and context. 相似文献
