The paper seeks to makes a contribution to a recent debate in the Journal about what a political economy of youth might look like. The paper will take up aspects of Sukarieh and Tannock’s [2016. ‘On the political economy of youth: a comment.’ Journal of Youth Studies 19 (9): 1281–1289] response to the initial contributions by Côté [2014. ‘Towards a New Political Economy of Youth.’ Journal of Youth Studies 17 (4): 527–543, 2016. ‘A New Political Economy of Youth Reprised: Rejoinder to France and Threadgold.’ Journal of Youth Studies.] And France and Threadgold [2015. ‘Youth and Political Economy: Towards a Bourdieusian Approach.’ Journal of Youth Studies], and will take the form of three ‘notes’: Capitalism: From the first industrial revolution to the third industrial revolution; Youth as an artefact of governmentalised expertise; The agency/structure problem in youth studies: Foucault’s dispositif and post-human exceptionalism.

These notes will suggest that twenty-first century capitalism is globalising, is largely neo-Liberal, and is being reconfigured in profound ways by the Anthropocene, bio-genetics, Artificial Intelligence (AI), and the Internet of Things (IoT). A political economy of twenty-first century capitalism, let alone a political economy of young people, must be able to account for a capitalism that in many ways looks like the capitalism of the First and Second Industrial Revolutions, but which is at the same time profoundly different as it enters what has often been described as the Third Industrial Revolution. It is these profound emergences that pose the greatest challenges for engaging with a political economy of youth.  相似文献

Scholars, educators, regulators, pundits, and other observers are advocating for regulation and oversight of direct-to-consumer (DTC) genomic testing. As a result, the technology has been subject of highly visible public and regulatory controversy. In this article, we explore the nature and the shape of the sentiment of public discourse about the DTC company, 23andMe. We conduct a quantitative content analysis and qualitative framing analysis on Tweets. We find that the discourse surrounding DTC genomics and 23andMe is largely positive. We also identify a number of frames users deploy to debate, discuss, and share their experiences with DTC genomics and 23andMe. We argue that these frames create meaning around this emerging technology for its users.  相似文献

What drives infants’ attention in complex visual scenes? Early models of infant attention suggested that the degree to which different visual features were detectable determines their attentional priority. Here, we tested this by asking whether two targets—defined by different features, but each equally salient when evaluated independently—would drive attention equally when pitted head‐to‐head. In Experiment 1, we presented 6‐month‐old infants with an array of Gabor patches in which a target region varied either in color or spatial frequency from the background. Using a forced‐choice preferential‐looking method, we measured how readily infants fixated the target as its featural difference from the background was parametrically increased. Then, in Experiment 2, we used these psychometric preference functions to choose values for color and spatial frequency targets that were equally salient (preferred), and pitted them against each other within the same display. We reasoned that if salience is transitive, then the stimuli should be iso‐salient and infants should therefore show no systematic preference for either stimulus. On the contrary, we found that infants consistently preferred the color‐defined stimulus. This suggests that computing visual salience in more complex scenes needs to include factors above and beyond local salience values.  相似文献

Abstract

The current study compared older children’s (11/12-year-olds) and adolescents’ (14/15-year-olds) vulnerability to false memory creation using two different methods (i.e., the Deese/Roediger-McDermott [DRM] and memory conformity paradigms) involving neutral and negative stimuli. In line with previous research, a developmental reversal effect was found for the DRM paradigm, which means that when employing this method children displayed lower false memory levels than adolescents. However, when using the memory conformity paradigm, the opposite pattern was found, with adolescents forming fewer false memories than children. This indicates that in a co-witness context, adolescents are less prone to memory errors than children. The emotional valence of the stimuli used in both paradigms did not notably affect the production of false memories. There was no statistically significant correlation between false memories as measured by the DRM and the memory conformity paradigms. Altogether, the current study indicates that there is no single type of false memory as different experimental paradigms evoke different types of erroneous recollections. Additionally, our study corroborates past findings in the literature concerning the issue of developmental reversal, strengthening the idea that under certain circumstances children might indeed be better witnesses than adolescents.  相似文献

Public debates about the rise in top income shares often focus on the growing dispersion in earnings, and the soaring pay for top executives and financial-sector employees. But can the change in the marginal distribution of earnings on its own explain the rise in top income shares? Are top executives replacing capital owners in the group of top-income earners, or are we rather witnessing a fusion of top capital and top earnings? This paper proposes an extension of the copula framework and uses it for exploring the changing composition of top incomes. It illustrates that changes in top income shares can easily be decomposed into respective changes in the marginal distributions of labour and capital income and the changing association between the two types of income. An application using tax record data from Norway shows that the association between top labour and capital incomes grew stronger between 1995 and 2005 in the top half of the wage and capital income distribution, though it declined for the top 1% of capital income receivers. A gender decomposition demonstrates that the association of wage and capital incomes at the top is particularly striking for men, whilst women are largely under-represented in the top halves of the two marginal distributions.  相似文献

Background

Previous physical activity (PA) tracking studies have examined the stability of overall PA and/or PA types, but few have investigated how specific types of sport/exercise track over the life course. The aim of this study was to determine how specific sports/exercises in midlife track and predict future sport/exercise and PA in men transitioning to old age.

Methods

Seven thousand seven hundred thirty-five men (aged 40–59?years) recruited in 1978–80 were followed up after 12, 16 and 20?years. At each wave men self-reported participation in sport/exercise. Frequent sport/exercise participants (>?1/month) reported the types of sport/exercise they engaged in. Men also reported total PA, health status, lifestyle behaviours and socio-demographic characteristics. Stability of each sport/exercise was assessed using kappa statistics and intraclass correlation coefficients. Logistic regression estimated the odds of participating in sport/exercise and being active at 20-year follow up according to specific types of sport/exercise in midlife.

Results

Three thousand three hundred eighty-four men with complete data at all waves were included in analyses. Tracking of specific sports/exercises ranged from fair to substantial, with golf being the most common and most stable. Bowls was the most frequently adopted. Odds of participating in sport/exercise and being active in old age varied according to sport/exercise types in midlife. Golf and bowls in midlife were the strongest predictors of sport/exercise participation in old age. Golf, cricket and running/jogging in midlife were among the strongest predictors of being active in old age. Compared to participating in just one sport/exercise in midlife, sampling multiple sports/exercises was more strongly associated with sport/exercise participation and being active in old age.

Conclusion

The stability of sport/exercise participation from midlife to old age varies by type. Specific sports/exercises in midlife may be more likely to predict future PA than others. However, participating in a range of sports/exercises may be optimal for preserving PA into old age.

This article aims to broaden the ways we conceptualize citizenship and implement citizenship education in social studies. To do so, the authors explore media texts as a curricular and pedagogical site for teaching lessons about citizenship. Specifically, the authors investigate how media drafts the boundaries of citizenship for Latin@ youth, and influences how young people come to understand who is and who is not perceived as a citizen entitled to rights and freedoms. Media texts, like formal social studies curricula, are powerful and enduring educators that shape how students know the world and imagine their place in it. Therefore, this article addresses how social studies teachers can integrate media texts into the classroom to explore representations of Latin@s and the impact that media has on our citizenship identities and experiences.  相似文献

Through a meta‐literature review, this paper examines the changing contours of Chinese sociology of homosexuality in contemporary China. It unfolds the different theoretical orientations and methodologies that construct the modern male homosexual subject under major socio‐economic and political changes. Chinese sociology of homosexuality started in the reform era and has been dominated by Western knowledge production and the political ideology of the communist party‐state. Fused with the bio‐medical model and the state's modernization project in the 1980s–1990s, the sociological study adopted a functionalist and positivistic approach with survey‐based methodology in the main which focused on the etiology of homosexuality. A new transnational knowledge production of sociology of homosexuality has formed since the 2000s which has shifted towards a constructivist/ post‐structuralist approach and reflexive qualitative methodology. The new sociological study examines the rise of male (as well as female) homosexual identity in China, questions the hetero/homosexual binary and discusses how an individual makes sense of homosexual identity to form same‐sex intimate relationships. By tracing the epistemology of homosexuality in contemporary China, this paper rethinks the dominance of the Western construction and the role of the state in shaping the knowledge of homosexuality and proposes alternative spaces for theorizing Chinese sexual identities, desires and practices.  相似文献

Technological advances provide increased ability to transfer human tissues—blood, organs, milk—from one body to another. This article analyzes mechanisms of reality construction in U.S. news to construct shared human breast milk. Articles used typifications and human interest stories to convey participants as victims, lay heroes, and villains. Milk banking was portrayed as institutionally integrated through associations, expert testimonies, and formalized procedures, making banked milk “pure gold.” Peer sharing was portrayed as institutionally opposed through institutional warnings, expert testimonies, informal procedures, and hypothetical atrocities, making peer milk “fool's gold.” Findings suggest that “biovalue” of human milk is interconnected with institutional processing.  相似文献

Adding to the debate on the integrative or marginalizing nature of female part-time work, this article provides a comparative analysis of the implications of female part-time work for different intrinsic job quality dimensions and job satisfaction. Drawing on national micro-data from Britain, Germany, the Netherlands, and Sweden, our multivariate analyses show cross-national similarities in terms of lower job learning opportunities for female part-timers. We found a significantly higher incidence of repetitiveness only among Swedish female part-timers and lower degrees of task discretion among British, Dutch, and Swedish women working part-time hours. Female part-timers were either equally satisfied with their work as female full-timers or even more satisfied. This held true also after accounting for the lower intrinsic job quality of part-time work. While women working part-time hours were as affected by their job quality characteristics as were full-timers, we conclude that the shorter hours of work per se provide an important additional source of job satisfaction.  相似文献
