Volatile Organic Compounds,Spectral Characterization and Morphology of Ammonium Nitrate Fuel Oil (ANFO) Samples

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.     

Crises and unpredictability in developing countries

Developing countries have suffered most of the financial crises in the context of the process of economic and financial globalisation. Both current and previous crises have revealed that unpredictability is a feature common to all the episodes which occurred during the process of globalisation. Although certain alarms went off, any of those external financial crises were actually predicted by the advanced methods in use for prediction and country risk analysis. Taking into consideration the information above, the aim of this paper is to check the ability to foresee external financial crises in developing countries of both the country risk index published by Euromoney and the Credit Ratings variable included therein. We have focused on the external financial crises that took place between 1992 and 2011, that is, in a full globalisation era. The results are negative. It appears that neither the index nor the sovereign ratings are able to reflect early enough the vulnerabilities that arise previously to the setting off the crisis episodes. This leads us to conclude that the existing models of country risk have limits. Thus, it would necessary to develop new instruments to measure this risk, considering uncertainty as an essential feature of the current economic and financial environment.     

The Shifting Framing Strategies and Policy Positions of the Bloque Nacionalista Galego

This article asks why, in contrast to other historic territories with a regional language, such as Catalonia and the Basque Country, nationalist parties in the Autonomous Community of Galicia receive less electoral support. Going beyond prior explanations of this counterintuitive political outcome, which were mainly based on economic, sociological, and institutional factors, this piece of research sheds light on the strategies of political parties. It examines not only nationalist forces but statewide ones that successfully compete in Galicia. Our analysis is focused on the Bloque Nacionalista Galego (BNG) because this is the only nationalist force that has consistently achieved representation within the regional Parliament. Along with BNG's translation into party positions in both the left-right and center-periphery dimensions, the article's main contribution is its updating of the BNG's three framing strategies: the nationalism/“Spanishism” (1982–1993), the “common project” discourse (1993–2005), and the sovereigntist one (2005 onward). Shifts in public opinion regarding the territorial model and other attitudes toward self-government are also examined.     

When school meets the Other: intercultural policies in the Basque inclusive school

ABSTRACT

Gatti, Irazuzta and Martinez address the intercultural public policies implemented in the education system of the Autonomous Region of the Basque Country (Spain). Focusing on the education system allows them to reconstruct the historicity of identity-alterity production in a region in which language has been central for the establishment of ethnic frontiers. More specifically, they examine the implementation of these policies in three pre-school and primary educational institutions in a multicultural neighbourhood of the city of Bilbao. They look at Euskara—the Basque language—as a key element of the us-them distinction. The various education models regarding language and the teaching in/of Euskara or Spanish pave the way for the specialization and spatialization of the schools analysed. ‘Integration’ policies are implemented in ethnically marked schools only, based on a rhetoric of interculturality that assumes that any ‘racial or ethnic discrimination’ can be overcome through knowledge of the Other. Moreover, the assessment of public policies through ‘interculturality figures and best practice’ developed to address the so-called ‘immigration issue’ promotes a protectionist intervention on behalf of the assumed social vulnerabilities of immigrant schoolchildren and their families, which are read as ‘problematic characteristics’. The article argues that, as a result of the approach based on the social conditions of immigrant children and their families in the Basque Country, the race issue evaporates.     

Rule growth and government effectiveness: why it takes the capacity to learn and coordinate to constrain rule growth

This paper asks whether strong bureaucracies can effectively constrain the continuously growing stock of rules in modern democracies through organizational coordination and learning. To answer this question, the paper analyzes the growth of rule stocks in the areas of environmental policy and social policy in 23 OECD countries over the period between 1976 and 2005. To do so, it develops a new measure of rule growth based on the content of laws and regulations rather than their length. The analysis highlights that effective bureaucracies are indeed better able to contain rule growth in these areas than weak bureaucracies. Since rules have to be implemented, countries suffering from bureaucratic capacity and quality constraints thus appear to be stuck in an implementation deficit trap. Appropriate implementation is not only inherently more challenging for countries with weak public administrations, but the body of rules to be implemented also tends to grow quicker in these countries.
