This article examines the use of military drones over the past 20 years. It includes the following: (1) a critical review of how drone warfare in the US-led ‘war on terror’ affected drone crews and those ‘living under drones’; (2) an analysis of how drone warfare in Ukraine and Russia differs from previous deployments of the technology; and (3) a careful assessment of what lies ahead, as national governments and technology firms race to develop AI-enabled drones and autonomous weapons systems on a broad scale. 相似文献

Zamorano, M. & Brandoni, D., 2013. Phylogenetic analysis of the Panochthini (Xenarthra, Glyptodontidae), with remarks on their temporal distribution. Alcheringa 37, 1–10. ISSN 0311-5518.To test the monophyly of Panochthini, a phylogenetic analysis including all the species traditionally referred to the tribe was conducted. The matrix included 16 species of Glyptodontidae and 35 characters, from which 14 correspond to the skull, four to the dentition, two to the cephalic armour, nine to the dorsal carapace and six to the caudal sheath. Propalaehoplophorus australis (Propalaehoplophorinae) was used to root the trees. Four most parsimonious trees were obtained (Tree Length = 75, CI = 0.65, RI = 0.70). The strict consensus tree (Tree Length = 77, CI = 0.64, RI = 0.68) has the following topology: Propalaehoplophorus australis (Glyptodon reticulatus (Hoplophorus euphractus (Panochthus jaguaribensis, P. intermedius (P. frenzelianus, P. tuberculatus (P. subintemedius, P. greslebini)))) ((Pseudoplohophorus absolutus, Plohophorus figuratus) (Nopachtus cabrerai, N. coagmentatus, Propanochthus bullifer, Stromaphorus compressidens, Phlyctaenopyga ameghini))). The results indicate that: 1, Panochthini is not a natural group but polyphyletic; 2, Panochthus is monophyletic and, concordant with recent proposals, Hoplophorus euphractus is its sister group; and 3, Nopachtus and Propanochthus are more closely related to species traditionally referred to ‘Plohophorini’ than to Panochthus. Nopachtus and Propanochthus, as the ‘Plohophorini’, are recorded from the latest part of the Neogene, whereas Panochthus and Hoplophorus euphractus are restricted to the Quaternary.[Martín Zamorano [marzamorano@fcnym]unlp.edu.ar], Departamento Científico Paleontología Vertebrados, Museo de La Plata, Paseo del Bosque, s/n, 1900, La Plata, Buenos Aires, Argentina.

This paper presents a methodology to combine the technology of the terrestrial laser scanner with the techniques of digital image processing in order to study damages on stony materials that constitute historical buildings. This methodology has been tested using intensity data from three terrestrial laser scanners with different technical specifications. The unsupervised classification algorithms were used for the classification of 2D intensity images derived from the 3D information obtained from laser scanner equipment. The results obtained show the potential of the use of intensity data from terrestrial laser scanner for the recognition and characterization of certain pathologies in building materials that constitute historical buildings. 相似文献

ABSTRACTSmall islands in peripheral regions are currently perceived as attractive tourist destinations. Governance plays an important role as a strategy for the revival of such destinations to achieve a more productive, environmental, social and sustainable management structure. ‘Good’ governance of a destination depends on all the actors involved in the tourism network. Such governance requires a redefinition of relations between government and society and minimal boundaries between public and private sectors. This paper has analysed the level of implementation of corporate social responsibility (CSR) in a tourist destination that is a biosphere reserve (BR), the island of Fuerteventura (Canary Islands, Spain), from a comprehensive approach involving a tourism supply chain (TSC) with private and public agents. The focal firms analysed within the TSC have been tourist accommodation establishments in Fuerteventura. The paper shows that the level of involvement of tourist accommodation in CSR is positive. However, this involvement is not sufficiently high to meet the requirements of a destination designated as a BR. Therefore, coordination policies should be developed that promote governance systems and further enhance sustainability in the destination. 相似文献

This article discusses the current state of the geography discipline in Spanish Universities after putting into action the European Higher Education Area. After decades of geography teaching, following theoretical and expository discourse models, the so-called Bologna Process has been a great opportunity to reflect what geography should be taught, how geography should be taught and why geography should be taught. Aspects such as competences, employability, learning methodologies, assessment, Geographical Information Systems domain have been incorporated into the renewal of geography teaching in Spanish higher education, which has contributed to the strengthening of geography in a context of geospatial technologies revolution and public awareness of spatial challenges. 相似文献

Territorial cohesion has become one of the main objectives in transport planning. This has fostered the development of assessment methodologies to quantitatively estimate the territorial impact of major transport infrastructures, which are particularly scarce at the intra-regional level. Linked to cohesion, polycentricity has been defined as the best spatial configuration to achieve balanced regions where population and opportunities are distributed among several entities linked by functional relationships. This paper aims to present a methodology to estimate these impacts based on the use of a new regional composite polycentricity indicator. The proposed indicator is tested by comparing the effects of conventional and high-speed railway (HSR) alternatives in the territorial system of a northern region of Spain. This quantitative assessment is a ranking tool for prioritizing rail network alternatives in terms of achieving the most balanced territory, which is especially relevant in countries where HSR networks follow cohesion goals. Our results show that new HSR links should only be complementary to regional railway services, and that the suppression of secondary lines should be avoided if a reduction in polarization is to be achieved. 相似文献

The question of the Anthropocene has gained increased notoriety among archaeologists recently. Precisely because of that, it is in need of thorough critique. The aim of this article is not to rule out the concept of Anthropocene, but to point out some of its problems: the relationship of Anthropocenic discourses with the emergence of an all-embracing biopolitical science; the inadequacies of the term, which blames all humans equally for a specific effect of modernity and capitalism; its failure to accept a diversity of origins (but also the problem of accepting overly deep origins), and the shortcomings of adopting a geological framework for archaeology. I thus suggest that the discipline has to define its own eras – also for the contemporary period – and that the Age of Destruction could be an apt archaeological counterpart for the Anthropocene. One of the benefits of outlining an archaeological era is that it brings modernity and capitalism back to the fore, and with them issues of power and conflict that have been largely lost in recent post-anthropocentric debates. 相似文献

Is populism necessary to the articulation of counter‐hegemonic projects, as Laclau has long argued? Or is it, as ?i?ek maintains, a dangerous strategy, which inevitably degenerates into ideological mystification and reactionary postures? In this paper, I address this question by exploring the politics of discourse in Evo Morales's Bolivia. While, in the years leading to the election of Morales, a populist ideological strategy was key to challenging neoliberal forces, once the hegemony of the new power bloc was stabilised, indigenous demands for emancipatory socio‐environmental change began to be perceived as a threat to resource‐based accumulation. In this context, the populist signifiers that originated in indigenous‐popular struggles were used by the Morales government to legitimise repression of the indigenous movement. I argue, therefore, that ideological degeneration signals a problem not with populism per se, but rather with the class projects and shifting correlations of forces that underpin it in changing conjunctures. 相似文献

This paper studies the vertical and horizontal interactions between federal and regional governments in terms of public deficits. Recent studies commonly restraint budget slippages to the incentives created by the institutional arrangements within a country. Alternatively, we estimate here a fiscal reaction function for the Spanish regions over the period 1995–2010, paying special attention to the impact of the federal fiscal stance on regional fiscal imbalances. Our results indicate that higher public deficits for the central government encourage larger fiscal imbalances at the regional level. This vertical interaction is interpreted in the context of yardstick competition models. We also find a significant impact from fiscal decisions taken by governments at the same decision‐making tier in a specific region. 相似文献
