Land grabbing has gained momentum in Latin America and the Caribbean during the past decade. The phenomenon has taken different forms and character as compared to processes that occur in other regions of the world, especially Africa. It puts into question some of the assumptions in the emerging literature on land grabbing, suggesting these are too food-centered/too food crisis-centered, too land-centred, too centred on new global food regime players – China, South Korea, Gulf States and India – and too centred on Africa. There are four key mechanisms through which land grabbing in Latin American and the Caribbean has been carried out: food security initiatives, energy/fuel security ventures, other climate change mitigation strategies, and recent demands for resources from newer hubs of global capital. The hallmark of land grabbing in the region is its intra-regional character: the key investors are (Trans-)Latin American companies, often in alliance with international capital and the central state. Initial evidence suggests that recent land investments have consolidated the earlier trend away from (re)distributive land policies in most countries in the region, and are likely to result in widespread reconcentration of land and capital. 相似文献
En este artículo propongo un examen de algunos de los obstáculos establecidos por las autoridades penitenciarias para llevar a cabo un proyecto etnográfico en una cárcel de mujeres de la Ciudad de México. Mi intención es plantear la importancia de formas de investigación-acción en contextos que, como el mexicano, se ven afectados por una profunda crisis de los aparatos del Estado –en particular presto atención a los sistemas educativo, penal y de justicia- que impacta con mayor severidad a grupos vulnerables como es el caso de las mujeres en reclusión que están en el centro de este estudio de caso. 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
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.
Ammonium nitrate fuel oil is an explosive mixture found in most antipersonnel landmines (APL) buried throughout the Colombian territory. During more than 50 years of internal conflict, the Colombian government has found that trained dogs are the most effective method to detect APL. However, the olfactive signature in ANFO is unknown and also if there are differences in detection related to the explosive manufacturing origin. Therefore, this work begins with the analytical validation of the method used to determine ammonia, in its derivatized form as carbamate, released by home-made ANFO using HS-SPME-GC-FID. Once validated, the method was used to identify ammonia and other organic volatile compounds present in ANFO, under laboratory and simulated field conditions. The validation process includes the evaluation of the optimum conditions for the derivation and extraction of butylcarbamate, the determination of the working ranges with linear response in FID, the limits of detection and quantification, the sensitivity, and the precision. The results of the validation established linearity and sensitivity in a concentration between 20 and 120 mg/L, as well as low limits of detection and quantification of 6.4 and 21.4 mg/L, respectively. Also, an intermediate precision of 11% for butylcarbamate with a repeatability of 8%. The validated method showed in real samples of home-made ANFO besides ammonia, the presence of low molecular methylamines, and also exhibited differences in volatile compositions according to the origin. The objective of this work is to offer a reliable analytical methodology for the extraction and analysis of volatile compounds from ANFO. 相似文献
