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

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

Do the illegal and legal rents of politicians affect municipal election outcomes? Empirical evidence
Bernardino Benito María-Dolores Guillamón Ana-María Ríos Francisco Bastida 《Local Government Studies》2019,45(4):546-568
This paper aims to analyse whether illegal (corruption) and legal rent extraction (high politicians’ wages) affect electoral outcomes at municipal level. We use an initial sample of 145 Spanish municipalities over 50,000 for two electoral periods: 2004–2007 (before the crisis) and 2008–2011 (during the crisis). Our findings show that neither illegal nor legal rent extraction impact on re-election in non-crisis times. However, we observe that citizens penalize legal rent extraction in the ballots during the crisis. Regarding the economic performance of the local governments, we find that its effect on re-election is important in non-crisis period. Nevertheless, in time of crisis, given that the economic situation is bad in general in the country, voters pay less attention to economic factors and focus on politicians’ behaviour. 相似文献

In recent years, Spanish local governments have come under increasing pressure to accommodate severe economic restrictions while maintaining their provision of local public services. We analyse overall cost efficiency in Spanish local governments during the period of the economic crisis (2008–2013), under four different non-parametric methodologies. Moreover, given how problematic it is to precisely define what municipalities do, we compare three different output models with various measures of quantity as well as quality. Results suggest that Spanish local government efficiency improved over the period 2008–2013 since budget expenditures (inputs) fell while local public services and facilities (outputs) were maintained. We also find evidence of the possible implications of service quality when measuring municipalities’ efficiency, and of structural differences in the average efficiency between municipalities located in different Spanish regions. Finally, our results confirm that the level and variation of efficiency scores are affected by the approach taken. 相似文献

Studying parallels between movement behaviour and violent actions can help understand interdisciplinary possibilities for prevention, intervention, mediation and post-conflict healing. This article explores the role of unconscious and conscious movement decision-making in violent/peaceful interactions. Thematic analysis of interviews was conducted with trainers in dance/movement peace practices working in fourteen countries. The doctoral research sociologically analysed shared beliefs and a framework that was previously applied to work in schools, expanding its potential for new settings and peace contexts. The framework illustrates five stages of decision-making (Flow/Tension, Attention, Intention, Action and Reflection/Evaluation) based on Warren Lamb’s and Rudolph Laban’s systems of movement analysis. Flow/Tension refers to physiological responses to conflict and the regulation of tension, discomfort and breath. Attention involves the development of spatial awareness and awareness of our immediate environment. The Intention stage fosters the capacity for self-evaluation, assertively addressing needs and mitigating ethical pressure. The Action stage involves understanding impulses, commitment and non-action. Reflection/Evaluation promote reflexivity in practitioners and participants and a dynamic evaluation of peace practices. By analysing contributions of dance/movement to peacebuilding, this article introduces a much-needed focus on the body in conflict and inform interpersonal and intergroup conflict interventions by educators, therapists and peace practitioners of all fields. 相似文献

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. 相似文献

This study sought to learn from Latino immigrant parents which and how state-level immigration policies impact their families. Fifty-four Latino immigrant parents participated in interviews. Constructivist grounded theory methods were used to complete the analysis. Results indicate that fear of detainment, deportation, and family separation affects participants emotionally and behaviorally. Participants experience exploitive practices in the workplace and through traffic infractions. Social support networks are constantly changing and weakened when families relocate in search of immigrant friendly communities. Simultaneously, parents develop strategies to protect their families against stringent immigration enforcement. Implications for practice, policy, and research are discussed. 相似文献
