Research on the health benefits and consequences of close relationships has suggested the linkage in daily emotions (i.e., coregulation) between close partners is an important relationship dynamic. While the coupling of daily emotions among family members (parent–child and marital dyads) has been widely documented, research examining emotional coregulation among ethnic minority youth during adolescence, a period marked by heightened emotion and risk for psychopathology, remains an important area in need of exploration. This study examined correlates of emotional coregulation in a sample of Mexican-origin adolescents (Mage?=?15.02, SD?=?.83) and their parents (Mage?=?41.93, SD?=?6.70). Dyads reported on daily levels of distress and happiness for 14 consecutive days across two waves of data collection a year apart (nwave1?=?428 dyads, nwave2?=?336 dyads). Dyads who reported getting along were more likely to coregulate their daily happiness. Importantly, coregulation of distress was only present in older adolescents who reported above average levels of internalizing symptoms. The results suggest coregulation of distress may shape or be shaped by poor mental health during the later years of adolescence, a time when youth may be establishing a degree of emotional autonomy from parents.

Across industrialized nations, children and teens are a highly prized target for the advertising industry because young people have a tremendous influence on family purchases; however, media scholars have long suggested that young people are a fundamentally vulnerable audience because they lack the necessary developmental competencies to adequately process and protect themselves from advertising communications. Yet, the precise developmental mechanisms have not been clearly articulated nor is there a clear understanding of how these competencies extend across childhood contexts (e.g., developmental phase, cultures). The current study seeks to lend clarity to this matter by looking at the potential influence that children’s executive function and emotion regulation have on the relationship between television exposure (as a proxy of exposure to advertising messages and other consumption-oriented media content) and consumer behavior across a broad range of ages from two wealthy industrialized countries. Mothers of young elementary school children (5–8 years) and early adolescents (9–12 years) in the Netherlands (N?=?333, 51.7% female child) and the United States of America (N?=?810, 49.6% female child) took part in an online survey to report on their child’s cognitive/affective development, media use, and consumer behavior (i.e., purchase requests, purchase related conflict). The results showed that across ages, executive function via attentional shifting moderated the link between purchase requests and purchase conflict, whereas positively valenced emotion regulation moderated the same relationship but only for older children. Lastly, the findings revealed that while there are differences in reported behavior among children in these two countries, the developmental processes tend to work in the same manner. The discussion focuses on what these findings mean for children’s consumer development as they approach adolescence and how researchers and child advocates should take these developmental factors into account when considering children’s potential vulnerability as consumers.

Using the 2017 post-election German Longitudinal Election Study (GLES), this article examines the voters for the Alternative for Germany (AfD) in the 2017 German federal election. We show that AfD voters in 2017 were truly ‘flesh of the same flesh’ of the mainstream German political parties, with the AfD drawing its voters from across the political party spectrum as well as from previous non-voters in 2013. In contrast to previous scholarship, we find that in most respects AfD voters in 2017 did not differ demographically from voters for all other parties, be that in terms of gender, education, employment status, and union membership. Furthermore, we find that AfD voters were not driven by anxiety about their own economic situation: they are no ‘losers of globalisation.’ Instead, AfD voters in 2017 were driven solely by two factors: their attitudes towards immigrants/refugees and anti-establishment sentiment/satisfaction with democracy in Germany.  相似文献

This paper seeks to analyze the policies on the cultural field implemented in Chile in recent years, explaining how expertise became fundamental and, more specifically, how this expertise evolved from that of an expert intellectual to that of an expert professional. The paper is based on the general hypothesis that the cultural field needs to be viewed in the context of a growing differentiation and autonomization of Chilean society, but that there are some interesting nuances to its evolution, particularly with regard to the transformation of expertise. This article argues that the expert in culture has a twofold nature, which is illustrated through drawing a timeline from the 1980s to the present, marking certain milestones in Chile’s national and cultural history. This timeline incorporates the intellectual work of two of Chile’s most important contemporary sociologists and experts in culture and cultural policies, Manuel Antonio Garretón and José Joaquín Brunner. A sample of their publications is analyzed and then contrasted to documents on cultural policy since the approval of the country’s institutional framework for culture in 2003, when the National Council for Culture and the Arts was created, gauging the influence of the expert intellectual on this new institutional framework and the thrust of public policies on culture. The paper concludes that the figure of the expert in culture has shifted from the “expert intellectual” to the expert of a professional kind, although the theoretical work of the former has continued to influence the debate around cultural policies to this day.  相似文献

This article tests the hypothesis that the attitude towards migration can be understood as a social seismograph for the degree of a society’s degree of democratisation. In this article I present my hypothesis and analyse the constellation of arguments within the public controversy following the so-called refugee crisis in Germany. I work out the internal problematics structuring the three main polarisations in this discourse. Most of the contributions analysed here are interventions rather than academic texts (albeit often authored by academics) making practical suggestions to cope with what they respectively relate to different definitions of crisis. Methodologically, this article is based on a thorough reading of essays and books and their relation to one another, with view to the current conjuncture. Understanding this ‘crisis’ after 2015 requires an approach attentive not only to the different ‘politics of polarisations’ within the public controversy but also to the real and phantasmal dimensions of the crisis. Although the figure of the refugee has began to occupy a central role in the discussion of migration policy, the debate has, I demonstrate, surprisingly little or nothing to do with migration whatsoever, but rather speak to the degree of required democratisation.  相似文献

The Polish response to the crisis that escalated across Europe in 2015, banning refugees from crossing its borders, has been one of the least welcoming in Europe. Poland has been reprimanded by the EU for its lack of solidarity with other countries that accepted refugees. The government’s response was that it does indeed welcome refugees as long as they are not Muslims, since letting Muslim refugees in would be a security risk. The figure of the Muslim terrorist posing as a refugee has become a key trope through which xenophobic nationalist politics have been employed. In this sense, Poland can be seen to be drawing particular inspiration from the Eurosceptic politics of Orbán’s Hungary while also reflecting a broader European trend towards Islamophobia in countries such as France, Germany, Sweden or the UK. This article maps responses to refugees from key public actors. It focuses on how three key players in the Polish public sphere—the Catholic Church, the State and civil society actors—responded to the looming perspective of welcoming refugees to Poland. The paper argues that the Polish response to the so-called refugee crisis should be analysed as subtext to a broader political change in the country towards nationalism that has as its goal to push out all foreign ‘invasion’. Mobilised within this are new and old manifestations of racism, suggesting that Poland’s long history of racial Othering and exclusion has not been sufficiently accounted for.  相似文献

What do experiments do for governance? Along with pragmatist and performative conceptions, we argue that they do not test already existing conditions of governing, but actively transform such conditions. Experiments help to realize specific models of governance by co-producing collective knowledge and material practices. We analyze a series of experiments with “emissions trading” in the USA between 1968 and 2000. The historical perspective shows how different types of experiments worked together: experiments in the laboratory and in the field supported each other in creating epistemic and political authority. This “ping-pong between lab and field” produced subjects and objects, facts and values, knowledge and power and aligned them in a new socio-material configuration, thus realizing emissions trading as a new form of governance.  相似文献

Scholars have consistently found that firms in developing countries adopt voluntary environmental programs (VEPs) in high numbers when their major trade partners are home to many VEP-certified firms. This reflects the following dynamic: Importers based in countries with many VEP-certified facilities demand similarly sustainable production processes from trade partners, and so exporting firms in partner countries adopt VEPs to signal their sustainable practices. Studies have identified characteristics of developing countries that make local exporting firms more likely to adopt VEPs as a signal; however, there has been little analysis as to the country-level characteristics that make importers more (or less) likely to demand VEPs from suppliers abroad, beyond having many VEP-certified firms themselves. This study considers this matter, theorizing that VEP diffusion only accompanies exporting to countries with high levels of income and education, as well as a high number of VEP-certified firms. Panel data analysis provides support for the theory, showing that developing countries only experience trade-based diffusion of ISO 14001 (a widely adopted VEP) through their exports to countries with high income and/or education levels. In contrast, exporting to countries that lack these characteristics creates no such diffusion, even where importing countries’ VEP certification levels are high. Instead, such trade produces a “stuck in the mud” effect, as developing countries’ certification levels stagnate even as those of their import partners rise.  相似文献
