Name-altering practices are common in many creative fields—pen names in literature, stage names in the performing arts, and aliases in music. More than just reflecting artistic habits or responding to the need for distinctive brands, these practices can also serve as test devices to probe, validate, and guide the artists’ active participation in a cultural movement. At the same time, they constitute a powerful probe to negotiate the boundaries of a subculture, especially when its features are threatened by appropriation from the mass-oriented culture. Drawing evidence from electronic music, a field where name-altering practices proliferate, we outline dynamics of pseudonymity, polyonymy, and anonymity that surround the use of aliases. We argue that name-altering practices are both a tool that artists use to probe the creative environment and a device to recursively put one’s creative participation to the test. In the context of creative subcultures, name-altering practices constitute a subtle but effective form of underground testing.  相似文献

ABSTRACT

The objective of this study is to identify the factors that contribute to the successful or unsuccessful integration of the Chinese diaspora in France. There is already a significant amount of literature that probes into the immigrant experiences of various other groups in France. However, the Chinese diaspora in France has remained insufficiently studied. This study aims to address this gap. The main findings of this study are that 1) unsurprisingly, the older the age of arrival, the less well integrated immigrants are in French society, 2) somewhat surprisingly, the less well integrated an immigrant is, the more likely he or she is going to believe that France is a tolerant and open-minded country, and 3) counterintuitively, the more deeply a member of the Chinese diaspora is immersed in French society, the more likely he or she is going to believe that France is hostile to people of Asian heritage.  相似文献

Applied researchers have been drawn to models that attribute the demonstrated cross‐country differences in intergenerational income transmission to government failures to invest in the human capital of poor children. To highlight another potential mechanism, the disincentive effects of labor market taxation and redistribution, we present a simple model that can explain cross‐country differences in intergenerational mobility and other previously observed empirical patterns. Empirical tests using data on income mobility, tax rates, and public expenditures largely support the model predictions. We conclude that the common presumption that intergenerational mobility largely measures fairness or opportunity, and the resultant policy recommendations, are premature. (JEL D31, J24, J62)  相似文献

Urban agriculture has been growing in popularity around the globe. As more land is allocated to urban agriculture, there is a greater need to understand arthropod herbivores and natural enemies in these sites. The area and production type of urban agriculture could influence the risk of pest outbreaks, since larger food production areas are hypothesized to host more abundant herbivore populations. To determine the potential for pest outbreaks, we sampled for pests and above-ground natural enemies at three types of sites with variable amounts of cultivated areas: residential gardens, community gardens, and urban farms. We focused on pests of brassica, a widely cultivated crop family attacked by cabbageworms and aphids. We investigated the relationships of garden characteristics and surrounding land cover on natural enemies and herbivores of brassica. More herbivores and plant damage were expected in larger community gardens and urban farms. However, herbivore populations were low across sites and not explained by garden characteristics or area of production. Herbivory on brassica averaged less than 15% at all sites. Limited plant damage and low herbivore numbers may be attributed to the positive effects of garden flowers on parasitoids and high numbers of parasitoids and generalist predators across sites. Garden area and floral resources had positive relationships with natural enemy abundance, although community composition was similar across sites. Since arthropod natural enemies were abundant across all types of food production, this suggests that urban agriculture is a beneficial habitat that could support regulating ecosystem services such as biological control.  相似文献

Despite increasing numbers of lesbian- and gay- (LG-) parent families, little research on LG-adoptive-parent families has examined parental beliefs and perceptions related to discussing their sexual minority status with their children. This study assessed 266 LG adoptive parents (160 lesbian mothers, 106 gay fathers) from the Modern Adoptive Families (MAF) study, a nationwide survey (2012–2013) of adoptive parents' pre- and post-placement experiences. A cultural socialization lens provided the framework for examining LG parenting beliefs and practices. Two measurement scales were developed to examine parents' perceptions and self-efficacy related to socializing their child about being in a sexual-minority-parent family. Results indicate that LG parents endorse the importance of unique socialization practices and generally feel confident engaging in these practices. Parent education, transracial adoption, endorsement of racial socialization, and socialization self-efficacy were positively associated with endorsement of socialization practices. Excellent reliability suggests the 2 scales have the potential of being psychometrically sound instruments with which to measure parental endorsement and related self-efficacy of socialization practices for families headed by sexual minority parents. Findings contribute to a deeper understanding of socialization and communication patterns in LG-headed families, especially those formed through adoption. Research, policy, and practice implications are discussed.  相似文献

In this article, we apply Peter Berger's theory of religion as a social construct to learn how The Church of Jesus Christ of Latter-day Saints (the Mormon Church) advances a heteronormative view of family relationships in the United States using a document titled The Family: A Proclamation to the World. Furthermore, applying cultural studies theory, we examine how believing Mormons negotiate the tension that arises when their secular values compete with those expressed by Church leaders. We argue that, although the Proclamation addresses a number of issues, the Church offers a closed text that emphasizes war narratives in which same-sex marriage is portrayed as a threat to LDS identity and the heteronormative family. This closed text is further legitimized by emphasis on the authority of Church leaders as oracles of God. The study participants largely accept the dominant narrative, and those who reject it, do so with some trepidation.  相似文献

Understanding student political attitudes—feelings about government and perceptions of its role—has long been of interest to social scientists. One factor that may influence political attitudes is belief in a just world, a complex psychological construct well established in the literature. Our study explores changes in social work students’ perception of a supportive role of government and their beliefs in a just world after one policy course using a pretest and posttest design. Student perceptions changed toward a more supportive government role, but there was no significant change for belief in a just world. The study contributes to empirical evaluation of the social work education policy class in terms of the Council on Social Work Education competencies.  相似文献

Nongovernmental organizations (NGOs) are established not with the aim of making profits but rather to provide social values by implementing different projects and activities. Transmitting complete information about these projects to society is a key element of transparency, as they operate within an atmosphere of public trust. Although there is a large body of literature on transparency in NGOs from a global perspective, very little research has been conducted on transparency within the area of projects and activities. This study takes a deeper look at this line and contributes to the literature on transparency in NGOs by proposing an index to measure the information transparency of the projects implemented by these organizations. The index captures three dimensions of the information about the projects (technical, financial, and scope) and makes it possible to: analyze the level of transparency of the portfolio of projects, detect the specific aspects that could be improved in each organization, and carry out comparisons among organizations.  相似文献
