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

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

Suicide is a major public health problem. Preventive measures have been sought by identifying risk factors. This study evaluates the association of childhood abuse and neglect with suicidal behavior at the time of psychiatric hospital admission. A total of 120 subjects (72 females; mean age 42.5 +/- 15.6 years old) admitted from August 2006 to July 2007 completed the Childhood Trauma Questionnaire (CTQ) to assess severity of exposure to childhood maltreatment. Thereof 62 (51.6%) patients presented with suicidal behavior at admission. Patients who had attempted suicide had significantly higher CTQ scores. Regression analysis indicated that shorter illness duration and severity of childhood maltreatment were predictors of suicidal behavior at admission. The study showed that inpatients of a psychiatric unit of a general hospital who experienced severe childhood abuse or neglect were significantly more likely to present with suicidal behavior. History of childhood maltreatment should be evaluated as an associated risk factor of suicidal behavior at admission of psychiatric inpatients.  相似文献

The proposed reflection intends to present the problem of judicial adjudication as a substantially-axiologically founded autonomous moment on the practical realization of law, and to explore this understanding in confrontation with external exigencies, mostly teleologically determined—hence, beyond strict deductive application, as a (normativistic-positivistic) syllogistic reference of facts to norms, and finalistically determined decision, as an option among possible alternatives to achieve specific aims. The main objective is to enter into a discussion on the methodological meaning of “integrity”, “hard cases” and “right answer”, as presented by Ronald Dworkin, and a critical reflection on the criticism(s) of that approach levelled by Neil MacCormick, so as to confront the relevance of principle and policy arguments, in order to bring about a different methodological approach, an alternative jurisprudentialist conception of adjudication, incorporating a practical-normative constitutive dialectics between legal controversy and legal system, such as that presented by Castanheira Neves. The focus will, then, be the legitimacy of the connection of arguments of principle and consequentialist arguments in adjudication, its selection and its justification, stating, therefore, a specifically assumed judicium, a judicative decision, having the legal system as its horizon of normative reference and of substantial and institutional autonomy.

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

The main goal of this research is to identify the reasons for gender differences in European volunteer rates in different types of voluntary organisations. To that end, we focus in volunteer rates at individual and national levels. We have drawn our data from the European Values Survey (EVS, 1999 and 2008). We have employed Logit models carrying out independent estimations for the individual likelihood of working as a volunteer for four categories: social awareness, professional, education and social justice. We have carried out independent estimations and we have also repeated estimations by gender subsamples. Our main result is that social factors might be even more relevant for decisions to volunteer than individual socio-economic factors. Specifying the peer group as much as possible allows better control of social variables. For example, studying the female volunteer rate is more relevant to control for the female national NGO membership rate than the total national rate. We also highlight important gender differences. For example, education is positively correlated with decisions to volunteer for both genders in all categories, but the educational effect is stronger for men in relation to professional activities and stronger for women in relation to social awareness and social justice activities.  相似文献
