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. 相似文献

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. 相似文献

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. 相似文献

ABSTRACTThis 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. 相似文献

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. 相似文献

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. 相似文献

We discuss how far accountability practices may be relevant to the success of independent regulators in countries without a tradition of administrative autonomy. We develop a conceptualisation of agency accountability failures and develop an analytical framework to examine the life and termination of the Spanish regulatory agency for telecommunications, CMT (Comisión del Mercado de las Telecomunicaciones - Telecommunications Market Commission). We argue that the CMT’s termination was related, among other reasons, to accountability failures in its institutional design. The paper relies on a variety of sources, including legislation, literature, media coverage, and semistructured interviews with agency officials and several stakeholders. 相似文献

In Nona Faustine’s photo series of self-portraits, White Shoes, the artist’s body becomes the agent in exposing the instability of racialized historical geography. Faustine revisits New York City’s landmarks to address what is missing or made invisible: a slave ship, a fugitive woman’s rebirth, or African burial grounds. Making herself visible where she is supposed to remain invisible, she highlights the unacknowledged connection between national wealth, nationalism, geography, and black labor. She discloses the topography of her travels as a changeable terrain, where one slips from the national iconic to ambiguous and finally, to the sacred. I suggest that Faustine doesn’t seek to democratize the extant historical maps, but to shift the terms of reading the city’s geography. She lifts the boundaries between the polarized pathways of knowing – the secularized and the sacred, the living and the dead, the verifiable and the missing. This shift is also made possible by the medium of photography and a feminist turn towards pleasures in one’s body. As Faustine comes to terms with the psychic and cultural inheritance of the diaspora, she moves from the collective body of pain towards black women’s pleasure in their own bodies without purging the history of sexual trauma. 相似文献
