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.     

Domestic elites and external actors in post-conflict democratisation: mapping interactions and their impact

Abstract

Following the end of the Cold War, post-conflict democratisation has rarely occurred without a significant international involvement. This contribution argues that an explanation of the outcomes of post-conflict democratisation requires more than an examination of external actors, their mission mandates or their capabilities and deficiencies. In addition, there is a need to study domestic elites, their preferences and motivations, as well as their perceptions of and their reactions to external interference. Moreover, the patterns of external–internal interactions may explain the trajectory of state-building and democracy promotion efforts. These issues deserve more attention from both scholars and practitioners in the fields of peace- and state-building, democracy promotion, regime transition and elite research. Analyses of external actors and domestic elites in post-conflict democratisation should therefore address three principal issues: (1) the identification of relevant domestic elites in externally induced or monitored state-building and democratisation processes, (2) the dynamics of external–domestic interactions and (3) the impact of these interactions on the outcomes of post-conflict democratisation.     

Die elementaren (Fremd-)Erfahrungen der Gabe

What holds society together? In his famous essay The Gift (1925) Marcel Mauss answers this question. However, as this paper shows, he does so not by formulating something like a theory of reciprocity as was often assumed after Claude Lévi-Strauss’ brought forward his structuralist interpretation of Mauss. Instead, the reason why gift practices create obligatory, cohesive social bonds lies in experiences of ?being-possessed“ and self-transcendence. This assumption is proven by means of a new and detailed reading of Mauss’ Essai sur le don as well as by the anti-utilitarian reception of Mauss’ work by the Collège de Sociologie (Georges Bataille, Roger Caillois, Michel Leiris). Overall, Mauss’ theory of the gift features important elements of a theory of posession and self-transcendence which focuses on the dimensions of experience and action. This is why one can discern a certain similarity between Mauss’ and the pragmatist theory of action. Only against that backdrop the social binding force of gift practices can be explained.     

Die Konstruktion der soziologischen Realität durch Forschungsrating

The article subjects the research rating of sociology, published in 2008 and carried out by an evaluation group on behalf of the German Science Council, to a secondary analysis. It is shown that the research rating constructs a reality of sociology which does justice neither to the variety of sociological knowledge production nor to its own claim of multidimensionality. Unwillingly, the peer reviewed article has imposed itself as the dominant criterion for assessing the research quality of research units against other types of publication and other activities such as externally funded research, knowledge transfer for practical problem-solving and knowledge diffusion in the public sphere. This preference also affected the assessment of entire research institutions with regard to their impact and efficiency as well as the devaluation of knowledge transfer and diffusion. In this way, sociology is limited to the type of professional sociology, while critical, public and policy-oriented sociology are displaced.     

Emile Durkheims Moralpolitik des Individualismus

Emile Durkheim was neither a political scientist nor a political sociologist. His oeuvre though exhibits a political dimension which is not easy to grasp. This article makes the attempt to reconstruct his project of a moral politics of individualism. How is it possible to institutionalize successfully what Durkheim calls moral individualism? Durkheim’s project rests upon two pillars: the scientific and scholarly pillar which aims at the establishment of sociology as a scientific discipline at universities. The political pillar which sets out to analyze the socio-structural, institutional, cultural conditions, forms and effects of individualism and the successful socialization of its values which allows to take seriously the rhetoric of the freedom and dignity of human beings in modernity. Durkheim’s project is confronted with the traditional images of politics and the social order to delineate the differentia specifica of his moral politics of individualism.     

Migration and the formation of transnational economic networks between Africa and Turkey: the socio-economic establishment of migrants in situ and in mobility

Turkey is often perceived as a transit place for migrants and refugees from the African continent. While many indeed continue to other countries and the country still precludes official local integration, the past decade has witnessed a growing number of African migrants settling in Istanbul. This article draws attention to the opportunity structures that enable this type of settlement. The article presents the argument that it is the presence of small-scale transnationally embedded traders from the same countries that enable the socio-economic stability of their co-nationals both locally as well as transnationally. The concept that is able to account for this development is establishment in situ and establishment in mobility, which is seen as exactly the definitional barrier between transit and settlement.     

Energy Transition by Conviction or by Surprise? Environmental Policy from 2009 to 2013

With the inauguration of the new federal government in 2009, many Germans were afraid of a rollback in energy and climate policy. Indeed, Christian democrats and liberals extended the operational lifespan of nuclear power plants but also continued with the previous green energy policy, known as Energiewende (energy transition). Beginning with a strong ideological separation, the Fukushima accident in Japan provoked a u-turn in nuclear policy, leading the government to abandon the lifespan extensions and to intensify the implementation of Energiewende, which became one of the core policy projects of the Merkel II cabinet then. Moreover, a new kind of consensus atmosphere was established which helped to settle some controversial environmental problems. Albeit policy outcomes concerning Energiewende were rather mixed, energy and climate policy was a rather low ranking issues during the federal election campaign in 2013.
