Food production has been changing significantly in recent years as a result of climate change and of growing demand for food. This article aims to understand the link between food security and international security in the context of climate change, applying a systematic and qualitative analysis of the literature using the bibliometric method. This research observes that climate change tends to affect agricultural productivity, exposing societies to risk and the need for migration. However, good governance, together with international cooperation, can reduce the hazards of food insecurity, strengthening ties between countries and stimulating a fairer and more inclusive form of international trade. 相似文献
The Democratic Alliance of Hungarians in Romania (RMDSZ) has been the most stable actor in the Romanian party system over the past two decades. However, in this article, we argue that beyond this apparent stability, the linkages between RMDSZ and its voters have undergone a gradual, yet significant shift. The ethnic block voting of Transylvanian Hungarians was closely connected to the concept of a self-standing and parallel “Minority Society,” and to the practices of institution building that the minority elites engaged in in the early 1990s. However, since its first participation in the Romanian government in 1996, RMDSZ has gradually departed from this strategy, a phenomenon that was also closely connected to a process of elite change within the organization. The present RMDSZ leadership puts less and less emphasis on policy programs that could reinforce the institutional system of the minority; consequently, it is unable (and unwilling) to organizationally integrate the community activists of the minority society who previously had played a key role in the process of (electoral) mobilization. At the rhetorical level, RMDSZ did not abandon the goal of building a parallel Hungarian minority society, but in its linkages to the Hungarian electorate, clientelistic exchanges have become predominant. 相似文献
Although many scholars of Central and Eastern Europe politics write about the relative weaknesses of civil societies, some studies delivered evidence of cases where interest groups were able to influence particular decisions and policies. Therefore, we aimed at identifying and examining the most influential national interest groups of eight different policy areas in post-communist Hungary hoping to explore the reasons for their success. Older generations of organisations benefit from political embeddedness, while newer advocacy groups rely more on legal instruments and public mobilisation. The operation of successful groups has not been affected by the strong political polarisation of the Hungarian party system. 相似文献
In this article we first point out that the different conceptualisations of Fair Trade, which are sometimes analytically contradictory, actually form a coordinated set. Understanding the Fair Trade project is impossible without taking these interlinked conceptualisations into consideration. Second, this set basically forms a mechanism of structural, institutional and moral reforms that guide actions. In this way Fair Trade sets out to produce less injustice than is usually the case with the structures and institutions that govern conventional trade. Nevertheless, it does not try to define what a just society is or even to perfectly define ‘fair trade’. This implies the adoption of a comparative justice angle. It is precisely by linking comparative individual situations with the structures that produce these situations that relative justice can find its strength and purpose. 相似文献
The regulatory regionalism approach has increasingly claimed that a new mode of regional governance is emerging globally. Regional policy regimes, developed in broad social and economic territorial areas, affect the internal transformation of the state. The authors plan to provide comprehensive empirical evidence about the emergence of worldwide regulatory regionalism by identifying how regulatory agencies have diffused very successfully within the regional level in recent decades. The paper aims to identify, using an original methodological design, the ways in which such diffusion of agencies occurred, as this may have theoretical relevance for the study of regulatory regionalism. The authors' hypothesis suggests that transnational political interactions in each regional cluster triggered agency diffusion, contributing to the development of the regulatory state within the countries of each region. To test this hypothesis, the authors employed a data set of regulatory agencies including the OECD (Organisation for Economic Co-operation and Development), and most Asian and Latin American countries (+59) from 1950 to 2007, for 15 sectors related to finance, risks, utility and competition. Bayesian data analysis was used to estimate the parameters of interest. 相似文献
Studies of Brazil's agricultural labor movement have generally neglected its relationship to the struggle for land, but this is neither fair nor accurate. Analyzing the rural labor movement's historical contributions to the land struggle in Brazil, this contribution has been organized into three main periods, emphasizing social relations, institutional activism and policy changes. It argues that despite the peculiarities of different historical contexts, rural labor consistently provoked protest against policies that privileged large landholders, whose concentration of power over land and labor resources continually worsened Brazil's ranking as one of the most unequal of nations. For more than half a century, the most constant opponent of this situation among the peasantry has been the National Confederation of Workers in Agriculture (CONTAG), a corporatist organization of rural labor unions founded in 1963. 相似文献
Identity and academic motivation are particularly at stake before the major transition to higher education. However, few studies have explored their changes and their longitudinal bidirectional links. To fill this gap, a three-wave study from the end of the 11th grade to the end of the 12th grade was conducted to explore changes in identity processes and academic motivation and to investigate how they might be interconnected over time. 599 adolescents (mean age 17.4; 59% girls) completed questionnaires containing measures about identity processes and three types of academic motivation: autonomous, controlled, and impersonal. Throughout the study span of one year, four identity processes increased: commitment making, identification with commitment, exploration in breadth and exploration in depth, while the process of ruminative exploration decreased. Simultaneously, late adolescents encountered an increase in impersonal motivation, more salient for boys. The results also revealed unidirectional links from motivation to identity processes, with no gender or age moderator effects: exploration in breadth and exploration in depth were positively predicted by autonomous motivation, ruminative exploration was positively predicted by autonomous, controlled, and impersonal motivation. In addition, impersonal motivation negatively predicted commitment making. On the other hand, identification with commitment positively predicted autonomous motivation. Practical implications are discussed.
DNA is one of the fastest growing tools in forensic sciences, increasing reliability in forensic reports and judgments. The use of DNA has increased in different areas of the forensic sciences, such as investigation of plant species, where plastid DNA has been used to elucidate and generate evidence in cases of traceability of genetically modified and controlled plants. Even with several advances and the practice of using DNA in forensic investigations, there are just few studies related to the identification of genetic tools for the characterization of drug and nondrug-types of Cannabis. Herein, the whole plastomes of two drug-type Cannabis are presented and have their structures compared with other Cannabis plastomes deposited in the GenBank, focusing in the forensic use of plastome sequences. The plastomes of Cannabis sativa “Brazuka” and of the hybrid Cannabis AK Royal Automatic presented general structure that does not differs from the reported for other C. sativa cultivars. A phylogenomic analyses grouped C. sativa “Brazuka” with the nondrug C. sativa cultivars, while the hybrid Cannabis AK Royal Automatic placed isolated, basal to this group. This suggests that the analysis of plastomes is useful toward genetic identification of hybrids in relation to C. sativa. 相似文献
Postmortem magnetic resonance imaging (MRI) is rarely used for the radiologic assessment of gunshot injuries, although it has clear advantages over postmortem computed tomography (CT) with regard to the imaging of soft tissue injuries. Another benefit in using MRI is that lodged projectiles composed of nonferromagnetic material such as lead present only marginal metal artifacts compared with severe artifacts on CT. This case report presents CT and MRI findings in a case with two gunshot wounds to the neck: a perforating wound and a nonperforating wound with a lead bullet lodged in the cervical spine. The decedent underwent CT and MRI before the scheduled autopsy. A ring of radiopaque material under the dermis in the fatty tissue was identified at both entrance wounds on CT, which was indicative of contact shots. The perforating gunshot was clearly indicated on CT by bullet fragments along the wound channel through the perforated 6th cervical vertebra and the fractured cricoid cartilage at the exit wound. The second trajectory, however, was only assumed based on the presence of gunshot residues at the entrance wound and the position of the lodged bullet. The radiologic assessment was severely impeded by the metal artifacts on CT. Barely noticeable metal artifacts on MRI allowed for clear visualization of the soft tissue injuries and the ruptured medulla oblongata. Only MRI clarified the soft tissue injuries of the brainstem noninvasively, which could provide specific and graphic information on the rapidity of death and the incapacitation of the victim. 相似文献
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
