Fluorescence of a Natural Fluorophore as a Key to Improve Fingerprint Contrast Image

The optical and morphological properties of resveratrol were investigated. This nontoxic fluorescent natural material, emitting in the visible blue light, was used as an optical marker, enabling the enhancement of the image contrast coming from relief pictures marked on challenging surfaces. By applying appropriated imaging softwares, this marker was verified to be very useful in the latent fingerprint recognition deposited on different wood surface types, mainly those with high level of roughness, where conventional forensic materials do not allow effective fingerprint image visualization.     

"We Live in a Country of UNHCR"—Refugee Protests and Global Political Society

Between September and December 2005 over 3,000 Sudanese refugees held a sit-in demonstration at the Mustapha Mahmoud Square in Cairo, Egypt, which is located directly across from the offices of the United Nations High Commissioner for Refugees (UNHCR). We analyze the events of the refugee sit-in as an act of global political society, one that saw people outside the realm of the political making demands for recognition and a say in the solutions being developed to relieve their plight. We argue that the sit-in at Cairo was fundamentally a disagreement between the refugees and the UNHCR over the politics of protection, care, and mobility. The article analyzes the strategies through which the refugees named their "population of care" in ways that countered the UNHCR's governmental strategies to classify the Sudanese refugee population in Cairo. We propose the concept of "global political society" as a way of thinking about global political life from the perspective of those who are usually denied the status of political beings. Global political society is a highly ambiguous site where power relations are enacted, taken and retaken by various actors, but in ways that do not foreclose opportunities for refugees to actively reformulate the governmentalities of care and protection.     

¡Que se Vayan Todos! Popular Insurrection and the Asambleas Barriales in Argentina

In December 2001, Argentina experienced a decisive crisis. A financial collapse accelerated by the massive flight of capital and the IMF denial of a new loan was followed by a popular insurrection which, by putting forward the slogan ¡ que se vayan todos, que no quede ni uno solo ! forced the resignation of national authorities. Whilst Duhalde's provisional government is negotiating the conditions for international financial support, faced with inflation and the rise of the dollar exchange rate, social mobilisation is expanding in new forms. This paper argues that the popular insurrection of December 2001 opened a space for the reinvention of the political as negative politics, the asambleas barriales constituting one example of this.     

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.     

Why Do Poor People Co-Hold Debt and Liquid Savings?

I examine the use of flexible savings-and-loan accounts offered by SafeSave, a microfinance institution serving poor slum dwellers in Dhaka, Bangladesh. I find that 59 per cent of the clients co-hold, meaning that they borrow at high interest rates and simultaneously hold low-yield liquid savings. Co-holders could immediately pay down, on average, 32 per cent of their debt using liquid savings and thus avoid significant interest payments. The results show that co-holders are more likely to be regular workers subject to little income uncertainty, suggesting that co-holding is not a consequence of liquidity needs. The paper discusses alternative explanations.     

The Greening of the Americas

ABSTRACT

This paper evaluates global capital’s ecological management and extends the assessment to the “green economy,” as developed in the first “green” neoliberal project, in Costa Rica. Costa Rica has been an important “laboratory” for experimentation in environmental governance mechanisms using debt-for-nature financial exchanges and other instruments of the Kyoto Protocol. I explore how “greening” can be understood as a new phase of capital accumulation, as I go into its five main aspects.     

Doing gender in Spanish same-sex couples. The distribution of housework and childcare

Housework and childcare have been considered mechanisms for ‘doing gender’ through the allocation of different functions to women and to men. Women continue to devote more time and effort to this type of work, in spite of their progressive incorporation into the labour market. Same-sex couples escape this gender binarism, and so this study set out to learn the distribution criteria work, as well as the influence of gender socialization when it comes to establishing this distribution. A qualitative investigation was carried out with 21 Spanish same-sex families. The results indicate that the majority of couples position themselves in an egalitarian discourse based on the absence of differentiated gender roles and a low level of specialization. No differences were found between male and female couples. Nevertheless, the female couples show higher levels of discontent when the distribution was not egalitarian. In conclusion, it is proposed that the effects of gender socialization are perpetuated beyond heterosexual relationships and also affect same-sex couples.     

Resilience as the new EU foreign policy paradigm: a pragmatist turn?

This article examines the rise of resilience discourses in EU foreign policy. The European Union Global Strategy (EUGS) refers to building state and societal resilience in its neighbourhood as one of the key strategic priorities of the EU. This article argues that the discourse of resilience that permeates the EUGS chimes well with a pragmatist turn in social sciences and global governance. The EUGS introduces resilience-building alongside an emphasis on flexibility, tailor-made approaches and the need for local ownership, capacity-building and comprehensiveness. More importantly, the new EUGS proposes “principled pragmatism” as a new operating principle in its foreign policy. While this might suggest a more pragmatic EU foreign policy, a closer examination of the EUGS discourse reveals significant tensions between a pragmatic and a principled foreign policy, which undermine the added value of resilience-building as a new foreign policy paradigm.
