The Protective Role of Ethnic Identity for Urban Adolescent Males Facing Multiple Stressors

Having a connection to one’s ethnic heritage is considered a protective factor in the face of discrimination; however, it is unclear whether the protective effects are persistent across multiple stressors. Furthermore, the dimensions of ethnic identity that reflect group pride/connection (affirmation) and exploration of the meaning of group membership (achievement) may operate differently in the face of stress. The present study examined the moderating role of ethnic identity affirmation and achievement on concurrent and longitudinal relationships between exposure to stress (discrimination, family hardship, exposure to violence) and antisocial behavior in a sample of 256 Black and Latino male youth (70 % Black) living in low-income urban neighborhoods. Using regression analysis, concurrent associations were examined at age 18, and longitudinal associations were tested 18 months later. We found that, among youth experiencing discrimination, high levels of achievement and low levels of affirmation predicted greater aggressive behavior and delinquency. Low affirmation also predicted more criminal offending in the face of discrimination. The two dimensions operated similarly in the context of family stress, in which case high levels of affirmation and achievement predicted lower levels of antisocial behavior. The findings suggest a differential role of the two dimensions of ethnic identity with respect to discrimination; furthermore, the coping skills that may be promoted as youth make meaning of their ethnic group membership may serve as cultural assets in the face of family stress.     

Neoliberalism and Academia in Morocco

This article analyses the impact of international aid flows and the process of global market integration in Morocco on the role of academia—meaning research, teaching and intellectual debate conducted largely, but not solely, through publications and conferences—in social and political change. Drawing upon interviews and analysis of secondary sources, the article suggests that international development agencies working in Morocco and national policy strategies to further globalisation have had consequences for academic research and outputs as well as on intellectual debate in general. The first effect is to support the cultivation of an academic elite in the social sciences and humanities whose research agenda is often connected to national and international policy agendas and, likewise, to limit the evolution of a broader-based national or regional academic debate based on independent research. The second is to raise the importance of private higher education, which is focused for the most part on teaching and not on independent research. The impact of both has been to undermine the status of the academic profession and the role of higher education in pushing forward public debate on critical issues beyond programmatic concerns, for instance illiteracy or migration; and to address more fundamental questions, such as adherence to neoliberal policies or the pervasiveness of political and social alienation in Morocco. More importantly, the decline of public higher education has symbolic significance in that it reflects disassociation of the state from supporting a connection between craft, identity and citizenship. Taking into account the consequences of the impoverishment of higher education for training, research and critical analysis, the article ends by calling on aid agencies to regard academic research and public universities as means to reinvigorate public debate and new thinking around national and local development issues.     

Researching difference and diversity within women's movements: Sisterhood and after

This paper illustrates how Sisterhood and After: The Women's Liberation Oral History Project has approached difference and diversity within the history of women's movements. I argue that the terms ‘difference and diversity’ cannot do justice to histories of black women unless they are used to highlight the impact of race on black women's experiences in women's movements. Furthermore given the widespread acknowledgment that there was tension in the British women's liberation movement over the marginalization, exclusion and racism faced by black and Asian women, the project sought to ensure that black and Asian women's varied experiences as campaigners were explored and we also asked our white interviewees about race. I show how the in-depth nature of the life history interview method holds the possibility for greater reflection on these vital and often unsettling issues in feminism's history.     

Earning through learning in legislatures

This inquiry applies Gary Becker’s theoretical notions of general and specific training to the experiential learning that occurs within political institutions, in particular the U.S. Congress. In the process, we isolate economic facets of these legislative experiences that influence the rental-value of human capital derived from congressional training. We identify four factors that structure legislators’ post-elective wages: pre-congressional salary, year of entry, tenure, and variables closely related to general training in Congress—specifically, assignment to powerful legislative committees, acquisition of broad skill packages, investment in expanding skill-set proficiencies, and to a lesser extent, life-cycle driven declines in such investments.     

The Financial Crisis and America's Capital Dependence on Japan and China

In the Post-Bretton Woods financial system (1972–2009), the United States has been able to borrow heavily from savings-rich countries like Japan and China. Its access to international capital has allowed the US to cover years of extravagant spending and to enjoy unmatched levels of power and plenty. For lenders, like Japan and China, access to the huge US export market has stimulated aggregate demand, which, in turn, has facilitated economic growth, high rates of employment, infrastructure expansion, and technological development.

Notwithstanding the mutual benefits, the massive scale of Post-Bretton Woods imbalances has placed the financial system under stress. Such macro-economic imbalances usually require a major rebalancing—either immediately through a financial crash or gradually through a “soft” landing.

The financial implosion in 2008 constituted a crash landing. To arrest the steep slide into a possible world depression, most of the leading economies, including especially the United States, have taken bold monetary and fiscal measures. However, these expansionary measures will deepen deficits and generate strong inflationary headwinds while placing pressures on currency exchange rates.

Following the 2008 financial earthquake and its wave of after-shocks, America's access to foreign capital is apt to become more restricted and increasingly expensive. This will erode one of the central structural sources of US power—its extraordinary fiscal flexibility, monetary autonomy, and global economic clout. With a weakened financial superpower, the world may become less prosperous, less stable, less predictable, and considerably more dangerous.     

The Developmental Significance of Adolescent Romantic Relationships: Parent and Peer Predictors of Engagement and Quality at Age 15

From a longitudinal sample (n = 957; 49.9% male; 77.3% White/non-Hispanic) of participants studied from infancy through age 15, adolescents’ depth of engagement in, and quality of romantic relationships were predicted from early and contemporaneous parent–child interactive quality and peer social competence. High quality maternal parenting and peer experiences prior to and during adolescence tended to be negatively associated with the depth of engagement in this domain for the full sample, yet positively associated with the quality of adolescents’ romantic relationships for the sub-set of individuals currently dating at age 15. Results reconcile contrasting views of the origins of romantic relationship engagement and quality and the positive versus negative developmental salience of romantic relationships in adolescence.     

People Trafficking: Conceptual issues with the United Nations Trafficking Protocol 2000

This paper examines the UN 2000 Trafficking Protocol in the context of international responses to the issue of people trafficking. Attention is drawn to the conceptual flaws in this new instrument regarding the failure to address domestic trafficking, not incorporating the purchasing and selling of people as defining characteristics of trafficking, and the lack of clarity around issues of prostitution. Framing the discussion within feminist theory, the essay concludes that women’s campaigning will continue to be crucial to putting issues such as human trafficking on the international political agenda. This is extended to affirm that people’s struggle against oppressive circumstances will lead the tackling of the underlying causes of trafficking.
