What role for trade in food sovereignty? Insights from a small island archipelago

The food sovereignty movement has been gathering momentum in advocating the rights of individuals and nations to control their own food systems. Alongside this is a mounting critical engagement regarding its privileging of local food production as the means through which to achieve this goal. Adopting a place-based approach, we explore the foodways of diverse communities across a small island archipelago – the Turks and Caicos Islands in the West Indies. Based on interviews and focus groups, we unpack narratives relating to islanders’ changing food practices and aspirations. These are understood as two competing but inter-related themes of disruption and reification of current practices shaped by wider food regimes in interaction with ecological challenges. Given that conditions of historic dependency implicate the islands in a myriad of dependent trade relationships, we argue that small island economies offer, and require, unique cases for understanding how sovereign conditions for trade might be developed in line with a food sovereignty framework. We underline the importance of an inter-disciplinary focus for bringing forth a nuanced understanding of what might be required to shape more sustainable, sovereign and secure food futures. Doing so is necessarily rooted in an appreciation of islanders’ accounts of social, economic, political and ecological change over time.     

Transnational delegation in global environmental governance: When do non‐state actors govern?

Non‐state actors – including firms, non‐governmental organizations, and networks – are now a permanent fixture in environmental politics. However, we know surprisingly little about when states choose to delegate to non‐state actors through multilateral treaties. This paper provides an historical picture, tracing patterns of delegation to non‐state agents in a random sample of multilateral environmental agreements from 1902 to 2002. I introduce a new unit of analysis – the policy function – to understand what non‐state actors actually do as agents. I find that analyses of delegation are sensitive to the unit of analysis; patterns of delegation at the treaty level are very different from those at the level of individual policy functions. While overall the decision to delegate to non‐state actors – what I term transnational delegation – is rare, it has grown over time. Complex treaties, those with secretariats, and those focused on the management of nature are more apt to delegate to non‐state actors. Non‐state agents fill a small, but growing role in multilateral environmental treaties.     

Who Chooses STEM Careers? Using A Relative Cognitive Strength and Interest Model to Predict Careers in Science,Technology, Engineering,and Mathematics

Career aspirations in science, technology, engineering, and mathematics (STEM) are formulated in adolescence, making the high school years a critical time period for identifying the cognitive and motivational factors that increase the likelihood of future STEM employment. While past research has mainly focused on absolute cognitive ability levels in math and verbal domains, the current study tested whether relative cognitive strengths and interests in math, science, and verbal domains in high school were more accurate predictors of STEM career decisions. Data were drawn from a national longitudinal study in the United States (N?=?1762; 48?% female; the first wave during ninth grade and the last wave at age 33). Results revealed that in the high-verbal/high-math/high-science ability group, individuals with higher science task values and lower orientation toward altruism were more likely to select STEM occupations. In the low-verbal/moderate-math/moderate-science ability group, individuals with higher math ability and higher math task values were more likely to select STEM occupations. The findings suggest that youth with asymmetrical cognitive ability profiles are more likely to select careers that utilize their cognitive strengths rather than their weaknesses, while symmetrical cognitive ability profiles may grant youth more flexibility in their options, allowing their interests and values to guide their career decisions.     

Does Everyone’s Motivational Beliefs about Physical Science Decline in Secondary School?: Heterogeneity of Adolescents’ Achievement Motivation Trajectories in Physics and Chemistry

Students’ motivational beliefs about learning physical science are critical for achieving positive educational outcomes. In this study, we incorporated expectancy-value theory to capture the heterogeneity of adolescents’ motivational trajectories in physics and chemistry from seventh to twelfth grade and linked these trajectories to science-related outcomes. We used a cross-sequential design based on three different cohorts of adolescents (N?=?699; 51.5?% female; 95?% European American; M _ages for youngest, middle, and oldest cohorts at the first wave?=?13.2, 14.1, and 15.3 years) coming from ten public secondary schools. Although many studies claim that physical science motivation declines on average over time, we identified seven differential motivational trajectories of ability self-concept and task values, and found associations of these trajectories with science achievement, advanced science course taking, and science career aspirations. Adolescents’ ability self-concept and task values in physics and chemistry were also positively related and interlinked over time. Examining how students’ motivational beliefs about physical science develop in secondary school offers insight into the capacity of different groups of students to successfully adapt to their changing educational environments.     

For lust or gain: perceptions of prostitutes in eighteenth-century London

This paper examines perceptions of lower-class female prostitutes in eighteenth-century London. This study challenges the prevailing argument that these perceptions fundamentally changed from ‘lusty whores’ to victims of poverty. An examination of Bridewell records, sermons, pamphlets, and the newspaper press, reveals that commentators believed that lust, poverty, and greed collectively explained what drove women to prostitution. Commentators recognized that, unable to make ends meet, many women turned to prostitution to survive, while also suggesting that others turned to prostitution because they believed they could gain considerable wealth by doing so. These same commentators asserted that some women were unusually lustful and that only prostitution would satisfy their insatiable desires. The simultaneous depiction of prostitutes in contradictory ways suggests that prostitution was not offensive to Georgian Britons solely because it involved women exchanging sexual favours for money, but because prostitution transgressed Britons’ deepest sensibilities about morality.     

Comparison of the M-Vac® Wet-Vacuum-Based Collection Method to a Wet-Swabbing Method for DNA Recovery on Diluted Bloodstained Substrates*†‡

A wet-vacuum-based collection method with the M-Vac^® was compared to a wet-swabbing collection method by examining the recovery of diluted blood on 22 substrates of varying porosity. The wet-vacuum method yielded more total nuclear DNA than wet-swabbing on 18 porous substrates, recovering on average 12 times more DNA. However, both methods yielded comparable amounts of total DNA on two porous and two nonporous substrates. In no instance did wet-swabbing significantly recover more DNA. The wet-vacuum method also successfully collected additional DNA on previously swabbed substrates. Mitochondrial DNA yields were assessed, and outcomes were generally similar to the nuclear DNA outcomes described above. Results demonstrate that wet-vacuuming may serve as an alternative collection method to swabbing on difficult porous substrates and could potentially recover additional DNA on previously swabbed substrates. However, swabbing remains the preferred collection method on substrates with visible stains and/or nonporous surfaces for reasons of convenience, simplicity, and lower cost relative to the wet-vacuum method.

Cognitive Vulnerabilities Amplify the Effect of Early Pubertal Timing on Interpersonal Stress Generation During Adolescence

Early pubertal timing has been found to confer risk for the occurrence of interpersonal stressful events during adolescence. However, pre-existing vulnerabilities may exacerbate the effects of early pubertal timing on the occurrence of stressors. Thus, the current study prospectively examined whether cognitive vulnerabilities amplified the effects of early pubertal timing on interpersonal stress generation. In a diverse sample of 310 adolescents (M age = 12.83 years, 55 % female; 53 % African American), early pubertal timing predicted higher levels of interpersonal dependent events among adolescents with more negative cognitive style and rumination, but not among adolescents with lower levels of these cognitive vulnerabilities. These findings suggest that cognitive vulnerabilities may heighten the risk of generating interpersonal stress for adolescents who undergo early pubertal maturation, which may subsequently place adolescents at greater risk for the development of psychopathology.
