This is an overview of a symposium on degrowth centred on Giorgos Kallis’ call for a socialism without growth, which insists on the need to be mindful of throughputs and the ecological consequences of any socialist project. Summarising and critically evaluating the various positions expressed by all the symposium participants, we find that Kallis’ ideas can be promising in drawing closer different Green Left perspectives, including ecosocialist, ecofeminist, and eco-Marxist. This complementarity is possible provided that degrowth proponents clearly align themselves politically on the side of the broad anti-capitalist Left and that the critiques expressed by the other symposium participants-especially with respect to Indigenous Peoples’ worldviews and practices and the dynamics that subtend the capitalist mode of production—become essential to degrowth platforms. We find already enough overlap among the diverse leftist positions represented in this Symposium for, at a minimum, continuing dialogue and, hopefully, politically beneficial mutual transformation and unification. 相似文献

This work describes an efficient and rapid test for typing 37 single nucleotide polymorphisms (SNPs) of the non-recombining region of Y chromosome (NRY) from a minimal amount of DNA using six PCR multiplexes. Markers were drawn following a hierarchical strategy based on the phylogenetic tree of Y chromosome proposed by the Y Chromosome Consortium [The Y Chromosome Consortium, A nomenclature system for the tree of human Y-chromosomal binary haplogroups, Genome Res. 12 (2002) 339-348]. Two multiplexes--arbitrarily named MY1 and MY2--were developed to explore the basal branches of the tree encompassing all the major clades A-R: MY1 for markers M35, M89, M172, M170, M9, M173, M45 and MY2 for markers M52, M216, M174, M181, M201, M91, M96, M214. Four multiplexes able of typing the more superficial branches typical of most frequent European haplogroups E3b, J2, R1 and I, were also developed and named MY-E3b (M78, M107, M224, M165, M148, M81), MY-J2 (M158, M68, M47, M102, M137, M67), MY-R1 (M17, M269, M18, P25, SRY10831.2) and MY-I (M72, M223, M26, M21, M161). SNP genotyping was carried out by hot-start PCR amplification with primers yielding fragments between 63 and 210 nucleotides, followed by minisequencing reaction based on dideoxy single-base extension and capillary electrophoresis of extension products. The sequential application of these multiplexes is a robust and effective resource for typing the most frequent European Y-SNP haplogroups, and appears to be suitable for forensic purposes and evolutionary studies. 相似文献

In the vast majority of immediate fire deaths, the mechanism of death is inhalation of toxic gases (especially carbon monoxide), direct thermal injury, or neurogenic shock due to the redistribution of the body's blood volume produced by surface heat on the skin. We present a suicidal case that is unusual because the mechanism of immediate fire death could arguably be explained in terms of a primitive autonomic reflex/the trigemino‐cardiac reflex. Although this reflex is well known to surgeons and anesthetists, with possible lethal consequences in the course of invasive surgical procedures on the head and neck region, it is much less familiar to forensic pathologists. 相似文献

The radiological search for GSR is crucial in burnt material although it has been rarely tested. In this study, thirty‐one bovine ribs were shot at near‐contact range and burnt to calcination in an oven simulating a real combustion. Computed tomography (CT) and magnetic resonance (MR) were performed before and after carbonization and compared with former analyses with DR (digital radiography); thus comparing the assistance, the radiological methods can provide in the search for GSR in fresh and burnt bone. DR demonstrated the greatest ability in the detection of metallic residues, CT showed lower abilities, while MR showed a high sensitivity only in soft tissues. Thus, DR can be considered as the most sensitive method in the detection of GSR in charred bones, whereas CT and MR demonstrated much less reliability. Nonetheless, the MR ameliorates the analysis of gunshot wounds in other types of remains with large quantities of soft tissues. 相似文献

Many scholars and policymakers are concerned that the emergence of drone warfare—a first step toward the robotics age—will promote instability and conflict at the international level. This view depends on the widely shared assumption among International Relations scholars that military hardware spreads easily, especially in the age of globalization and real-time communications. In this article, we question this consensus. Drawing from the literature in management, we advance a new theory of diffusion of military innovations and test its two underlying causal mechanisms. First, we argue that designing, developing, and manufacturing advanced weapon systems require laboratories, and testing and production facilities, as well as know-how and experience that cannot be easily borrowed from other fields. Second, we argue that the adoption of military innovations requires both organizational and infrastructural support. We test our two claims on three types of combat-effective drones: loitering attack munitions (LAMs), intelligence surveillance and reconnaissance drones (ISR), and unmanned combat autonomous vehicles (UCAVs). We find that even wealthy, advanced, and militarily capable countries such as the United States, the United Kingdom, Germany, and France have struggled to produce or adopt such platforms. We conclude that concerns about the diffusion of drone warfare appear significantly exaggerated, as do claims that globalization redistributes military power at the global level. More generally, our analysis sheds light on how the interaction between platform and adoption challenges affects the rate and speed of diffusion of different military innovations. 相似文献

Negative advertising is frequent in electoral campaigns, despite its ambiguous effectiveness: Negativity may reduce voters' evaluation of the targeted politician but may have a backlash effect for the attacker. We study the effect of negative advertising in electoral races with more than two candidates with a large-scale field experiment during an electoral campaign for mayor in Italy and a survey experiment in a fictitious mayoral campaign. In our field experiment, we find a strong, positive spillover effect on the third main candidate (neither the target nor the attacker). This effect is confirmed in our survey experiment, which creates a controlled environment with no ideological components or strategic voting. The negative ad has no impact on the targeted incumbent, has a sizable backlash effect on the attacker, and largely benefits the idle candidate. The attacker is perceived as less cooperative, less likely to lead a successful government, and more ideologically extreme. 相似文献
