Determination of MDMA, MDA, MDEA and MBDB in oral fluid using high performance liquid chromatography with native fluorescence detection

This paper describes the analytical methodology for the determination of MDMA, MDA, MDEA and MBDB in oral fluid. After a liquid–liquid extraction, the analysis was carried out by high performance liquid chromatography (HPLC), with fluorescence detection. The detector wavelength was fixed at 285 nm for excitation and 320 nm for emission. The mobile phase, a mixture of phosphate buffer (pH = 5) and acetonitrile (75:25), and the column, Kromasil 100 C8 5 μm 250 mm × 4.6 mm, allowed good separation of the compounds in an isocratic mode in only 10 min. The method was validated and showed good limits of detection (2 ng/mL) and quantitation (10 ng/mL) for all the amphetamine derivatives. No interfering substances were detected. A stability study of these compounds in oral fluid stored at three different temperatures (−18, 4 and 20 °C) over 10 weeks was conducted, showing a time-dependent degradation of the four compounds.     

Mortality in Mexico. Some considerations on rural-urban differentials

"In this essay, certain aspects related to rural-urban mortality differentials in Mexico are analyzed....[These include] the availability, advantages, and limitations of different sources of information and the disparity of levels and tendencies according to particular indicators of acceptable reliability, especially those deriving from recent demographic surveys conducted in Mexico. The findings confirm an inverse ratio between size of settlement and mortality, and reveal a widening of the differentials over time." (SUMMARY IN ENG)     

Moving beyond ideas of laddism: conceptualising ‘mischievous masculinities’ as a new way of understanding everyday sexism and gender relations

Abstract

This article engages with current debates on ‘lad cultures’ by questioning how we understand the term in the specific context of everyday sexism and within groups of men varying in age. Further to this, using a feminist and critical masculinity studies perspective, the article will explore how men do not necessarily comprehend their behaviour within the framework of lad culture or within the continuum of sexual violence. Through discussion of ethnographic and interview data collected over a year at a site historically associated with lad cultures, that of a Rugby Union club in Northern England, an alternative way of conceptualising masculinity and everyday sexism, ‘mischievous masculinities’, is proposed. Men in the research practiced what I term mischievous masculinities, whereby they implemented ‘banter’ to aid in both the construction and de-construction of sexist ideas within the rugby space. Performing mischievous masculinity enabled men of all ages to both engage in and simultaneously challenge everyday sexism in ways they understood to be ‘innocent’. However, the continual framing of banter as ‘just a laugh’ demonstrated that this form of sexism can be construed as problematic, due, in part, to its subtlety, in relation to more overt and violent sexist practices. A key difference between the men in my research and previous theorising of ‘lad culture’ is the recurring theme amongst older participants that ‘I should know better’, demonstrating consciousness of the sexist and problematic connotations which could be drawn from this interaction. This notion of mischievous masculinities then, in the context of a life course perspective, can be seen to challenge more established notions of an unreflexive lad culture, thus affording a more nuanced understanding of everyday sexism amongst more diverse groups of men than currently exists, as well as allowing for men’s agency in a specific site.     

Local Institutions and the Politics of Urban Growth

This article uses a political market framework to analyze how the structure of local political institutions affects the relative political influence of development and environmental interests in the context of urban growth. Using panel data from 406 Florida cities from 1998 to 2003, the empirical analysis finds important interaction effects between the structure of city executive branch institutions and interest group variables. The economic and political forces driving urban growth do not operate identically in all cities—they vary as a function of institutional context. Institutional structure helps determine which interest groups have their preferences reflected in local land-use changes and development patterns. The resulting patterns suggest a "sustainability paradox" wherein richer, environmental interests push for the preservation of environmental amenities while at the same time accelerating the number of residential units built in a community.     

Culture on the Rise: How and Why Cultural Membership Promotes Democratic Politics

Selectively using Tocqueville, many social scientists suggest that civic participation increases democracy. We go beyond this neo-Tocquevillian model in three ways. First, to capture broader political and economic transformations, we consider different types of participation; results change if we analyze separate participation arenas. Some are declining, but a dramatic finding is the rise of arts and culture. Second, to assess impacts of participation, we study more dimensions of democratic politics, including distinct norms of citizenship and their associated political repertoires. Third, by analyzing global International Social Survey Programme and World Values Survey data, we identify dramatic subcultural differences: the Tocquevillian model is positive, negative, or zero in different subcultures and contexts that we explicate.     

Gettin’ Down Home With the Neelys: gastro-porn and televisual performances of gender,race, and sexuality

This article illuminates how performances of gender, race, and sexuality are integrated with representations of food and food performance in contemporary American cooking television. Interrogating the intersections of food, gender, race, sexuality, and performance, this essay explores how the cable-television show, Down Home with the Neelys, depicts a nouveau gastro-porn anchored in the perceived pornographic level of blackness itself. The author reveals the ways that food and performances of food become a medium of gendering and racialization employed by American popular media. Through the lens of reality television, shows like Down Home (re)produce a certain type of black heterosexuality and gendered enactments of domesticity and space, while challenging dominant televisual reflections of black love and labor. The author argues that the Neelys self-consciously employ a vernacular aesthetic performative of “down home” (a uniquely classed, temporally–spatially situated, and sexualized blackness) to exploit the phenomenon of gastro-porn in a highly lucrative performance that signals the entangled artifice of gender, race, and sexuality. More than offering culinary expertise and education, such cooking instruction reveals the pedagogy of gender, race, and sexuality as visual lessons of a complex and contradictory authenticity. This essay reveals television cooking shows as critical sites for considering the domestic laboring of gendered and racialized sexualities. In particular, shows like Down Home evince the ways that race continues to be rendered in visual terms and the enduring edibility of blackness.
