This article explores the implications of the April 2007 United Nations Security debate on the security dimensions of a changing climate for international climate change politics. Specifically, our analysis focuses on whether and how security concerns have been addressed in past international political debates on climate change and considers whether the Security Council debate, which emphasized the threat of climate-related conflict, reflects a discursive shift. We elaborate on two general discourses on the relationship between environment and security, which we call environmental conflict and environmental security . Using content and discourse analysis, we demonstrate that both the historical climate change debate and the more recent Security Council debate have been informed by the environmental security discourse, meaning that a discursive shift has not taken place. We conclude by considering the possibility of a future discursive shift to the environmental conflict perspective and argue that such a shift would be counterproductive to the search for an effective global response to climate change.  相似文献

This essay addresses the legal meanings of the phrase hefa quanyi (lawful or legitimate rights and interests), an important Chinese legal phrase that is frequently found in many Chinese laws and legal documents, and whose interpretation is claimed by various scholars to affect the alienability of people’s rights. It first challenges the existing translations of the phrase into Italian and English. It secondly delves into its history and etymology, studying the legal meanings that the phrase has had in the various texts of the Constitution of China. It is suggested that hefa quanyi is not the semantic and legal equivalent of Western ‘rights and interests’, but rather that the phrase retains its etymological meaning of ‘power and negatively-connoted profit’. It is further argued that the adjective hefa (lawful) in the phrase is used to impose constraints on the rights and interests that the Chinese people are entitled to.

Synthetic cannabinoids are sprayed onto plant material and smoked for their marijuana‐like effects. Clandestine manufacturers modify synthetic cannabinoid structures by creating closely related analogs. Forensic laboratories are tasked with detection of these analog compounds, but targeted analytical methods are often thwarted by the structural modifications. Here, direct analysis in real time coupled to accurate mass time‐of‐flight mass spectrometry (DART‐TOF‐MS) in combination with liquid chromatography quadruple time‐of‐flight mass spectrometry (LC‐QTOF‐MS) are presented as a screening and nontargeted confirmation method, respectively. Methanol extracts of herbal material were run using both methods. Spectral data from four different herbal products were evaluated by comparing fragmentation pattern, accurate mass and retention time to available reference standards. JWH‐018, JWH‐019, AM2201, JWH‐122, 5F‐AKB48, AKB48‐N‐(4‐pentenyl) analog, UR144, and XLR11 were identified in the products. Results demonstrate that DART‐TOF‐MS affords a useful approach for rapid screening of herbal products for the presence and identification of synthetic cannabinoids.  相似文献

Despite numerous instrumental achievements, canines are still considered the most effective field method for explosive detection. However, due to strict explosive regulations and safety requirements, it can be a challenge for agencies with "bomb dogs" to train using neat explosive materials. This establishes a need for non-explosive canine training aids with the same volatile component profiles as the explosives that they represent. In order to compare mimic materials to their explosive counterparts, a technique must be established that not only allows for identification of volatile compounds but also can monitor changes in the headspace profile over time with respect to time and temperature. The Automated Training Aid Simulation using SPME (or ATASS) was developed for that purpose. As described, ATASS was used to observe changes in the volatile profile of three explosives (Composition C-4, 2,4-dinitrotoluene (DNT), and triacetone triperoxide (TATP)) and respective prototype training materials (0.1% by mass C-4, 1% by mass 2,4-DNT, and 1% by mass TATP). Samples were prepared in vials and metal tins within a gallon (≈ 3785 mL) paint can to simulate common field techniques for canine training. Monitoring these materials in real time provides a better understanding of the major volatile components present and how the relative abundances of these components can change over time. The results presented indicate that ATASS successfully allows for a sufficient comparison between explosive and non-explosive training materials.  相似文献

在当今的司法程序中越来越多地应用科学技术来证明争议事实,但这种应用也存在一些争议和问题。有关证据和证明程序规则的存在.在本质上,并没有同科学证据的应用和采纳在任何方式上存在冲突。相反,如果存在非认知性的程序规则,其结果是这样的规则应该被撤销。除了物理、化学、工程学和遗传学等“解释性科学”得以广泛应用之外,心理学、社会学...  相似文献

The Earth System Science Partnership, which unites all major global change research programmes, declared in 2001 an urgent need to develop “strategies for Earth System management”. Yet what such strategies might be, how they could be developed, and how effective, efficient and equitable such strategies would be, remains unspecified. It is apparent that the institutions, organizations and mechanisms by which humans currently govern their relationship with the natural environment and global biochemical systems are not only insufficient—they are also poorly understood. This article presents the science programme of the Earth System Governance Project, a new 10-year global research effort endorsed by the International Human Dimensions Programme on Global Environmental Change (IHDP). It outlines the concept of earth system governance as a challenge for the social sciences, and it elaborates on the interlinked analytical problems and research questions of earth system governance as an object of study. These analytical problems concern the overall architecture of earth system governance, agency beyond the state and of the state, the adaptiveness of governance mechanisms and processes as well as their accountability and legitimacy, and modes of allocation and access in earth system governance. The article also outlines four crosscutting research themes that are crucial for the study of each analytical problem as well as for the integrated understanding of earth system governance: the role of power, knowledge, norms and scale.  相似文献

When faced with commingled remains, it might be assumed that a more “masculine” pelvis is associated with a more “masculine” cranium, but this relationship has not been specifically tested. This study uses geometric morphometric analyses of pelvic and cranial landmarks to assess whether there is an intra‐individual relationship between the degrees of sexual expression in these two skeletal regions. Principal component and discriminant function scores were used to assess sexual dimorphism in 113 U.S. Black individuals. Correlation values and partial least squares regression (PLS) were used to evaluate intra‐individual relationships. Results indicate that the os coxae is more sexually dimorphic than the cranium, with element shape being more sexually dimorphic than size. PLS and correlation results suggest no significant intra‐individual relationship between pelvic and cranial sexual size or shape expression. Thus, in commingled situations, associations between these skeletal elements cannot be inferred based on degree of “masculinity.”  相似文献
