Fast Discrimination of Marijuana using Automated High-throughput Cannabis Sample Preparation and Analysis by Gas Chromatography–Mass Spectrometry

In the United States, federal law and many state laws differentiate between marijuana and industrial hemp through delta-9-tetrahydrocannabinol (THC) levels, whereby the latter is defined as ≤0.3 percent THC on a dry weight basis. Many traditional cannabis identification methods employed by crime laboratories cannot accurately determine total THC quantities in accordance with federal and state regulations, or do so with increased time, labor, and risks of instrument damage. In order to quickly distinguish positive marijuana samples, a method was developed to identify plant material with a total THC level >1%. This novel, automated dispersive pipette extraction (DPX) method uses tip-based technology and an automated liquid handler to enable fast, hands-free selective isolation of THC and its precursors for downstream gas chromatography–mass spectrometry (GC-MS) analysis. The workflow proceeds with no repetitive manual effort and reduced need for instrument maintenance while enabling crime labs to legally identify marijuana through the detection of total THC above 1%. Recovery of THC using the DPX extraction method was 93% at 30 µg/mL and 78% at 500 µg/mL. Similarly, THCA-A recovery was 100% at 30 µg/mL and 74% at 500 µg/mL. Samples evaluated in a blind study (proficiency, hemp, and nonprobative case samples) were all accurately identified as greater than or less than 1% THC, with samples containing <1% THC being identified as “cannabis” and subjected to more discriminative analysis as needed.     

Linking Social Anxiety and Adolescent Romantic Relationship Functioning: Indirect Effects and the Importance of Peers

Peer relationships undergo dramatic shifts in form and function during adolescence, at the same time the incidence of socially evaluative fears sharply rises. Despite well-established links between social anxiety and broader interpersonal functioning, there is a dearth of research evaluating the impact of social anxiety on functioning in close relationships during this developmental stage. The present study examines the impact of social anxiety on functioning in close friendships and romantic relationships during adolescence. From a developmental psychopathology perspective, it was expected that social anxiety would influence functioning (quality, length, satisfaction) in romantic relationships through its influence on functioning in same- and other-sex friendships. Participants included 314 adolescents (60.5 % female, 14–19 years of age) with a prior or current history of romantic relationship involvement. Structural equation modeling was used to test a mediation model positing an indirect pathway from social anxiety to romantic relationship functioning through functioning in close same- and other-sex friendships. Given known gender differences in social anxiety and relationship functioning, gender also was explored as a potential moderator. Results supported the hypothesized indirect pathway whereby social anxiety was associated with impairment in same-sex friendships; functioning in same-sex friendships was associated with functioning in other-sex friendships, which was associated, in turn, with functioning in romantic relationships. While the hypothesized indirect pathway was significant among both boys and girls, there was greater continuity of functioning between same- and other-sex friendships for girls. These findings highlight the importance of examining the multiple downstream effects of social anxiety on perceived social functioning in adolescence, and suggest that continuity may exist for maladaptive patterns of socialization, particularly across developmentally salient close relationships.     

Cook,eat, man,woman: understanding the New Alliance for Food Security and Nutrition,nutritionism and its alternatives from Malawi

The Group of Eight Countries (G8) launched the New Alliance for Food Security and Nutrition to improve nutritional outcomes through private sector involvement in agricultural development. The accession of Malawi to the Alliance reveals the assumptions behind the intervention. We show that while the New Alliance may seem to have little to do with nutrition, its emergence as a frame for the privatization of food and agriculture has been decades in the making, and is best understood as an outcome of a project of nutritionism. To highlight the failings of the approach, we present findings from the Soils, Food and Healthy Communities Initiative in northern Malawi, which has demonstrated success in combatting malnutrition through a combination of agroecological farming practices, community mobilization, women's empowerment and changes in intrahousehold gender dynamics. Contrasting a political economic analysis of the New Alliance alongside that of the Soils, Food and Healthy Communities Initiative shows the difference between a concern with the gendered social context of malnutrition, and nutritionism. We conclude with an analysis of the ways that nutrition can play a part in interventions that are inimical, or conducive, to freedom.     

<Emphasis Type="Italic">BodiMojo</Emphasis>: Efficacy of a Mobile-Based Intervention in Improving Body Image and Self-Compassion among Adolescents

Mobile interventions promoting positive body image are lacking. This study presents a randomized controlled evaluation of BodiMojo, a mobile application (app) intervention grounded in self-compassion to promote positive body image. A sample of 274 adolescents, mean (SD) age?=?18.36 (1.34) years, 74% female, were allocated to a control group or used BodiMojo for 6 weeks. Appearance esteem, body image flexibility, appearance comparison, mood, and self-compassion were assessed at baseline, 6, and 12 weeks. Significant time by group interactions emerged for appearance esteem and self-compassion, with appearance esteem and self-compassion increasing in the intervention relative to the control group. These findings provide preliminary support for BodiMojo, a cost-effective mobile app for positive body image.     

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.     

Never Pick a Fight with an Ugly Person,They’ve Got Nothing to Lose

In the 1970s, social psychologists conducted numerous studies analyzing physical appearance as a social variable. More recent studies in the social sciences appear to have abandoned this topic as unimportant; in any case, very few social scientific studies have been found that incorporate a measure of attractiveness into their analyses. The present study seeks to revive the emphasis on physical attractiveness as a social variable by testing the relationship between crime severity and physical attractiveness, i.e., by presenting evidence to suggest that physically unattractive men commit more serious offenses.

Land grabbing,social differentiation,intensified migration and food security in northern Ghana

This paper argues that large-scale land appropriation is displacing subsistence farmers and reworking agrarian social relations in northern Ghana. The recent wave of farmland enclosure has not only resulted in heightened land scarcity, but also fostered a marked social differentiation within farming communities. The dominant form of inequality is an evolving class of landless and near-landless farmers. The majority of households cope with such dynamics by deepening their own self-exploitation in the production process. The fulcrum of this self-exploitation is gendered property rights as part of the conjugal contract, with men exerting a far greater monopoly over land resources than had previously been the case. Due to acute land shortages, women’s rights to use land as wives, mothers and daughters are becoming insecure, as their vegetable plots are being reclassified as male-controlled household fields. The paper further documents the painful choices that landless farmers have to make in order to meet livelihood needs, including highly disciplined, yet low-waged, farm labor work and sharecropping contracts. In these livelihood pathways, there emerge, again, exploitative relations of production, whereby surplus is expropriated from land-dispossessed migrant laborers and concentrated with farm owners. These dynamics produce a ‘simple reproduction squeeze’ for the land-dispossessed. Overall, the paper contributes to the emerging land grabbing literature by showing geographically specific processes of change for large-scale mining operations and gendered differentiated impacts.     

Trust Matters: Enhancing Government Legitimacy through Participatory Budgeting

Legitimacy is a problem of contemporary governance. Communities lack trust in elected officials—in their effectiveness, fairness, and representation of the public interest. Participatory budgeting (PB)—a set of democratic processes where residents determine how to spend a public budget—helps bridge that distance by letting the public make spending decisions. Since 2011, some of New York City’s (NYC) council members have been implementing PB with their capital budget—setting aside a million dollars in their districts each budget cycle for PB. Participatory budgeting has the potential to rebuild relationships between government and communities. Using data from over eighty interviews conducted by New York University (NYU) graduate students in 2013 and 2014 with PBNYC participants over two years, this article suggests that in council districts using PB, residents have greater feelings of access to and voice in local government, and better understanding of the complexities of spending public monies, often leading to a more positive view of government officials, and bolstering legitimacy of local government.     

Grassroots Citizenship at Multiple Scales: Rethinking Immigrant Civic Participation

Given the finding that the marginalized are less politically engaged, we examine those who are arguably the most marginalized—the undocumented—and ask: what underwrites recent cases where the undocumented have been politically engaged in meaningful and substantive ways? Additionally, how does this compare with the existing literature on the practice of citizenship for those with formal rights? And what are the implications for our understanding of political participation in the contemporary USA? We seek to address these questions by examining cases where undocumented immigrants act like citizens even though they lack formal political rights. Our cases deviate from previous literature which argues that more marginalized people participate less and that those without formal rights engage in contentious politics in lieu of “normal,” institutional politics. Our analysis of the DREAMers and of immigrant worker centers helps us rethink this traditional distinction between “normal” and contentious politics. Moving beyond a focus on the specific actions that fall into each category, we instead emphasize how the context for these actions is crucial to understanding the foundations of political participation. In particular, we argue that the same “normal” political actions taken by citizens versus noncitizens reveals different foundations underneath; for those without formal rights, what underwrites participation in “normal” and contentious politics alike is what we call grassroots citizenship. We examine how the political participation of undocumented workers and DREAMers takes place within immigrant organizations and how it relies on three pillars: solidarity, critical analysis, and collective action. While previous literature has emphasized the urban and local nature of active, alternative citizenships, our cases operate at multiple scales, demonstrating how grassroot citizenship can be leveraged and “scaled up” to state and national levels. Additionally, through an analysis of grassroots citizenship, we get some purchase on the question of why politicians sometimes listen to people who cannot vote.
