The current global political economy is characterised by the intensifying economic interaction of BRICS and ‘near BRICS’ economies, with emerging powers increasing their influence in neighbouring regions. The growing partnership between Turkey and Russia constitutes a useful case study for examining this transformation, in which Western supremacy and US hegemony are under increasing challenge. Turkish–Russian relations shed light on broader themes in global political economy. First, significant economic interdependence may be generated among states with different political outlooks, in the form of loose regional integration schemes driven by bilateral relations between key states and supporting private actors or interests. Second, growing economic interdependence may coexist with continued political conflict and geopolitical rivalry, as indicated by the Syrian and Ukrainian crises. An important strategy that emerges is the tendency to compartmentalise economic issues and geopolitical rivalries in order to avoid negative spill-over effects. This facilitates the coexistence of extensive competition with deepening cooperation, as reflected in relations in the field of energy. 相似文献

At the turn of the first millennium, the rise of autonomous communes and city-states in northern Italy coincided with the development of a particular sense of attachment to land and city, which is widely labeled as civic patriotism. Neither the transformation of these collective identities across time nor the macrostructural dynamics behind this transformation has received much attention. Through an examination of these communes and city-states from the eleventh to the sixteenth century, this paper unpacks different forms of collective identities that prevailed in northern Italy in different periods of time, all of which have previously been labeled as “patriotism” in the literature. The differentiation I propose between “communal patriotism,” “civic nationalism,” and “city-state chauvinism” presents a more nuanced picture which highlights the differences in the ways these collective identities are produced, reproduced, and transformed. My analysis also discusses the role played by macrostructural dynamics (e.g., changing climate in the macropolitical economy as well as inter-city-state system in the peninsula) in transforming these collective identities. Alongside a longue durée evolutionary transformation, there were two conjunctural moments which created ruptures in the transformation of collective identities in northern Italy: The first took place during the territorialization of the communes and the conquest of the contado in the mid-twelfth century and the second occurred in the aftermath of the crisis of the fourteenth century. 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

Guillermo O’Donnell’s influential work ‘Delegative Democracy’ set the discourse on a peculiar type of democracy. Lying between representative democracy and authoritarianism, the uniqueness of delegative democracy lies in its features, including an absence of horizontal accountability, strong centralised rule, individual leadership with unchecked powers, a cult figure embodying the nation and clientelist practices. While delegative democracies seem to arise out of presidential systems, Turkey, though a parliamentary system, has also displayed the distinctive features of delegative democracies. This paper identifies three characteristics of delegative democracy, which are responsible for the lack of democratic consolidation, if not the erosion of democracy itself: anti-institutionalism, an anti-political agenda and clientelism. Arguing that delegative democracy is the best concept with which to examine contemporary Turkey, the paper lays out how, post-2011, Turkey has demonstrated the three elements of delegative democracy. The final section discusses the implications of the Turkish case for scrutinising the very possibility of delegative democracy in parliamentary regimes. 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

Postmortem computed tomography (PMCT) is integrated into the evaluation of decedents in several American medical examiner offices and medicolegal death investigative centers in many other countries. We retrospectively investigated the value of PMCT in a series of firearm homicide cases from a statewide centralized medical examiner’s office that occurred during 2016. Autopsies were performed or supervised by board-certified forensic pathologists who reviewed the PMCT scans prior to autopsy. PMCT scans were re-evaluated by a forensic radiologist blinded to the autopsy findings and scored by body region (head–neck, thoracoabdominal, and extremities). Injury discrepancies were scored using a modified Goldman classification and analyzed with McNemar’s test. We included 60 males and 20 females (median age 31 years, range 3–73). Based on PMCT, 56 (79.1%) cases had injuries relevant to the cause of death in a single body region (24 head–neck region, 32 thoracoabdominal region). Out of these 56 cases, 9 had a missed major diagnosis by PMCT outside that region, including 6 extremity injuries visible during standard external examination. Yet all had evident lethal firearm injury. We showed that PMCT identifies major firearm injuries in homicide victims and excludes injuries related to the cause of death in other regions when a single body region is injured. Although PMCT has a known limited sensitivity for soft tissue and vascular pathology, it can be combined with external examination to potentially reduce or focus dissections in some of these cases depending on the circumstances and medicolegal needs. 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
