The effect of plastic wrapping on decomposition rate and carrion fauna of rabbits (Oryctolagus cuniculus L.) was examined in spring in a semi-urban area in North Algeria. All decomposition stages were observed in all carcasses, with the same durations in the control but different durations in the wrapped carcasses. Decomposition of the carcasses in the plastic wrapping was significantly slower than that of the exposed ones. A total of 12,516 specimens, belonging to 36 families and 69 species, were morphologically identified. Thirteen species of forensic relevance were also identified at the molecular level using the cytochrome c oxidase I (COI) barcode region, and the sequences were submitted to online databases. Wrapping had a significant effect on species composition (χ2 = 569.269, df = 55, p < 0.001). Higher species richness, abundance, and diversity were found in the control group. No significant difference in species abundance was observed between the treatments. The plastic wrap did not influence the accessibility of carcasses to insects, nor did it delay the arrival of necrophagous flies. This study provides basic information on the decomposition and arthropod colonisation of wrapped remains and contributes to the literature on North African carrion fauna. 相似文献

Crossing borders in North America after 9/11: ‘regular’ travellers’ narratives of securitisations and contestations 总被引:1,自引:0,他引:1

This article is part of a larger project on ordinary border crossings and state practices in North America. The changing border governmentalities in the region focusing on securitising their borders against potential terrorist threats and the increased emphasis on the managing of population flows have led to a reduced mobility for certain travellers as opposed to others. The construction of potentially safe and ‘un-safe’ subjects through profiling on the basis of race, ethnicity, national origin, gender, religion and socioeconomic background and the increasing use of biometrics have impacted upon travellers’ mobilities. In the North American context, the Mexican state has undergone significant modernisation in terms of its border control capacities, thus enhancing not only its capacity as a buffer state, but also its performative sovereignty, and is therefore an interesting case to study. This article aims to analyse how these transformations in border governmentalities have affected the mobility of ‘ordinary’ travellers, and how they have developed coping strategies and resistances towards the potential curbing of their respective mobilities. 相似文献

Since the 2003 Iraq war, the Middle East and North Africa has entered into a New Regional Cold War, characterised by two competing logics: on the one hand, the politicisation of sectarianism opposing a Saudi-led Sunni bloc against an Iran-led Shia bloc and, on the other, an intra-Sunni cleavage around the mobilisation of political Islam, embodied by the Muslim Brotherhood and its supporters vs its opponents. Blending Buzan and Weaver’s regional security complex theory with Donnelly’s notion of ‘heterarchy’ and applying it to the cold wars the region has experienced, the similarities and differences between the Arab Cold War of the 1950s/60s and the New Regional Cold War reveal the increasing number of heterarchic features within the regional security complex: multiple and heterogeneous power centres, different power rankings, a more visible and relevant role of non-state and transnational actors, and the fragmentation of regional norms. 相似文献

中国传统的"华夷观"长期影响着朝鲜半岛,朝鲜各朝代的封建统治者也以"小中华"自居。"尊华攘夷"、"慕华贱夷"是朝鲜人传统的文化观念,这一文化观念严重影响了民族意识和民族文化的健康发展。自进入清代以来,朝鲜人自以为所谓华夷秩序大乱,华夏文明之真传移到了朝鲜,并因此而深感自豪;同时,自感传续华夏文明之真传的责任重大,虔诚地维护传统文化,唯恐有丝毫的亵渎。尽管当时由于地理大发现、西势东渐,人类文明格局发生了巨大变化,但朝鲜卫道士们一直将中华以外的文明视为"夷狄"之货,采取不屑一顾的态度。在如此僵化愚腐的意识氛围中,北学派的先驱洪大容率先提出了"华夷一也"的新观念,实现从"慕华贱夷"、"尊华攘夷"到"华夷一也"思想的飞跃。在东亚率先打破传统的"华夷观"是朝鲜北学派的一大特点,在朝鲜唤起了民族主体意识,为朝鲜学习世界先进文化,吸收新的世界文明做了理论准备。 相似文献

19世纪60年代,俄国远东地区出现了第一批朝鲜移民。朝鲜人向俄国移民的初期,移民得到积极安置,此后每年都有大批朝鲜人迁入俄国,他们逐渐成为俄国远东地区的主要劳动力。朝鲜人向俄国远东地区移民,不仅受东北亚国际关系的影响,更取决于俄国、朝鲜乃至中国的国内状况,它是在国内外综合因素作用下所引发的一种国际移民现象。 相似文献

国际发展援助对于援助国来说通常被作为实现国家利益的对外政策工具,而对于受援国来说,发展援助可以为本国经济建设和社会发展提供诸多帮助。因此,发展援助对于援助国和受援国双方的经济发展都具有相当积极的意义和作用,是一种具有互利和双赢效益的国家间经济合作方式和国际关系模式。根据朝鲜的要求及现实需要,国际社会对朝援助正由人道主义援助向发展援助转变。国际社会对朝发展援助目标是促进朝鲜经济、政治、社会发展,援助领域将更多地集中在基础设施建设、农业和提高行政管理能力等方面。在此过程中,需要解决如何筹措对朝援助巨额资金、如何提高对朝援助透明度和效率等课题。 相似文献

Analysis of footprints can reveal very important clues which can be used as forensic evidence in crime scene investigation. Apart from giving idea about the bare foot morphology and individualistic characteristics, the footprints are also indicative of the body size of the person. The present study is an attempt to establish the correlation between footprints and body weight of individuals. The sample for the present study consists of 50 male subjects ranging in age from 18 to 30 years. The subjects belonging to Gujjar caste were randomly taken from a village near Chandigarh city in North India. Three kinds of bilateral footprints were taken from each subject. First, the footprints with the subject's normal weight were taken, the footprints were taken when the subject holds 5 kg weight in his hands, then the footprints were taken when the subject holds 20 kg weight in his hands. In this way, the present study analyses 300 bilateral footprints obtained from 50 individuals. Nine measurements were taken on each footprint using precise and defined landmarks. The measurements of these three kinds of footprints were compared with each other and t-test was employed to see the significant variation. Some of the measurements of the footprints were altered significantly when the subject was subjected to 20 kg weight. However, there is no significant change when the subject holds 5 kg weight in his hands. Body weight was also estimated using regression method from the measurements of these three kinds of footprints. The utility of the study in offences like sexual assault, homicide, theft, burglary, mugging, stealing, shoplifting, dacoity, etc. has been discussed. 相似文献

Since the 1980s, the USA has fought cocaine in the Andes with carrots and sticks: interdiction and crop eradication wield the sticks, while Alternative Development (AD), which offers economic assistance to farmers who voluntarily abandon illicit cultivation, provides the carrots. Yet cocaine continues to permeate US streets, and rural Andean communities remain isolated from the legitimate economy. Many critics blame US belligerence for compounding the Andean drug war. The underlying problem with the existing strategy, however, might not be the aggressiveness of its military sticks, but the flimsiness of its development carrots. The inability of AD to persuade farmers to abandon coca cultivation may be causing US policy makers to over-apply military solutions – often inflaming rural communities and exacerbating regional instability in so doing. Few legal crops can match the earning power of coca. The article therefore suggests that the US carrot could be made more attractive by adopting a Venture Development model which helps rural farmers to process their legal produce into high-quality finished goods that command premium prices. Such a strategy could conceivably choke the cocaine engine by applying market-based forces to address market-based realities. 相似文献
