In 2010, the Government of Ontario, Canada passed the controversial Far North Act. The Act purportedly aims to promote land use planning and sustainable development while recognising Aboriginal and Treaty rights. There are, however, early warning signs that the Act could be a breeding ground for future conflict between Indigenous peoples and other stakeholder groups. This article adopts a ‘sons of the soil’ conceptual framework to explore the mechanisms that could give rise to the escalation of Indigenous vs. non-Indigenous conflict. The findings provide important insights for theorising the contentious politics around land and territory in diverse settler-colonial contexts.  相似文献

Nearly a decade ago, fentanyl reappeared in the United States illicit drug market. In the years since, overdose deaths have continued to rise as well as the amount of fentanyl seized by law enforcement agencies. Research surrounding fentanyl production has been beneficial to regulatory actions and understanding illicit fentanyl production. In 2017, the Drug Enforcement Administration (DEA) began collecting seized fentanyl samples from throughout the United States to track purity, adulteration trends, and synthetic impurity profiles for intelligence purposes. The appearance of a specific organic impurity, phenethyl-4-anilino-N-phenethylpiperidine (phenethyl-4-ANPP) indicates a shift in fentanyl production from the traditional Siegfried and Janssen routes to the Gupta-patent route. Through a collaboration between the DEA and the US Army's Combat Capabilities Development Command Chemical Biological Center (DEVCOM CBC), the synthesis of fentanyl was investigated via six synthetic routes, and the impurity profiles were compared to those of seized samples. The synthetic impurity phenethyl-4-ANPP was reliably observed in the Gupta-patent route published in 2013, and its structure was confirmed through isolation and structure elucidation. Organic impurity profiling results for illicit fentanyl samples seized in late 2021 have indicated yet another change in processing with the appearance of the impurity ethyl-4-anilino-N-phenethylpiperidine (ethyl-4-ANPP). Through altering reagents traditionally used in the Gupta-patent route, the formation of this impurity was determined to occur through a modification of the route as originally described in the Gupta patent.  相似文献

The storage and use of explosives is regulated at the state and federal level, with a particular focus on physical security and rigorous accounting of the explosive inventory. For those working with explosives for the training and testing of explosive-detecting canines, cross-contamination is an important concern. Hence, explosives intended for use with canine teams must be placed into secondary storage containers that are new, clean, and airtight. A variety of containers meet these requirements and include screw-top glass jars (e.g., mason jars). However, an additional need from the explosive-detecting canine community is secondary containers that can also be used as training aids whereby the volatiles emitted by explosives are emitted in a predictable and stable manner. Currently, a generally accepted method for the storage of explosives and controlled emission of explosive vapor for canine detection does not exist. Ideally, such containers should allow odor to escape from the training aid but block external contaminates such as particulates or other volatiles. One method in use places the explosive inside a permeable cotton bag when in use for training and then stores the cotton bag inside an impermeable nylon bag for long-term storage. This paper describes the testing of an odor permeable membrane device (OPMD) as a new way to store and deploy training aids. We measured the evaporation rate and flux of various liquid explosives and volatile compounds that have been identified in the headspace of actual explosives. OPMDs were used in addition to traditional storage containers to monitor the contamination and degradation of 14 explosives used as canine training aids. Explosives were stored individually using traditional storage bags or inside an OPMD at two locations, one of which actively used the training aids. Samples from each storage type at both locations were collected at 0, 3, 6, and 9 months and analyzed using Fourier Transform Infrared (FTIR) Spectroscopy and Gas Chromatography–Mass Spectrometry (GC–MS) with Solid-Phase Microextraction (SPME). FTIR analyses showed no signs of degradation. GC–MS identified cross-contamination from ethylene glycol dinitrate (EGDN) and/or 2,3-dimethyl-2,3-dinitrobutane (DMNB) across almost all samples regardless of storage condition. The contamination was found to be higher among training aids that were stored in traditional ways and that were in active use by canine teams.  相似文献

Human hairs are one of the most commonly encountered items of trace evidence. Currently, conventional methods for hair analysis include microscopic comparison and DNA analysis (nuclear and mitochondrial). Each approach has its own drawbacks. Hair proteins are stable and offer an alternative to DNA testing, as demonstrated with proteomics for distinguishing humans. However, proteomics is complicated and requires identifying peptides to remain intact following harsh sample preparation methods. Alternatively, the actual amino acid content of a hair sample may also offer important identifying information and actually requires proteins and peptides to be broken down completely rather than remaining intact. This study evaluated the discriminating power of using hair amino acid ratios to differentiate hair samples from 10 unrelated individuals with dark colored hair. Hair proteins were digested, derivatized, and analyzed using gas chromatography–mass spectrometry. Amino acid ratios were calculated for each individual and comparisons using ANOVA and post-hoc pairwise t-test with Bonferroni correction were made with amino acid ratios for individuals. Overall, out of the 45 possible pairwise comparisons between all hair samples, 38 (84%) were differentiable. Out of the 36 possible pairwise comparisons between brown haired individuals, 32 (89%) were considered differentiable using univariate statistics. Multivariate statistics were also attempted but, overall, univariate models were sufficient for exclusionary purposes. These results indicate that amino acid ratio analysis can potentially be used as an exclusionary method using hair if DNA analysis cannot be performed, or to corroborate conclusions made following microscopic analysis.  相似文献

Over the past two decades, natural disasters have severely hit the Southeast Asian region causing dramatic environmental, economic and social consequences. Through the lens of Beck's risk society framework and the theory of reflexive modernization, this article attempts at empirically taking stock of how the Association of Southeast Asian Nations (ASEAN) is addressing disaster risk through the creation of new regional institutions and mechanisms. In particular, it argues that the accumulation of the experience of catastrophes is leading ASEAN members towards the development of new precautionary initiatives to deal with disasters, and to forge a new way forward for the promotion of disaster cooperation and joint emergency response. The article is divided into five sections, which will only consider initiatives endorsed within the ASEAN framework. The first introduces risk societies as forms of modern societies and of the insecurities of the present world. In the second section attention is drawn to natural disasters as a paradigmatic example of Beck's risk society. The third section explores how ASEAN normative governance is evolving to include the issue of disaster management within its security and social agenda. Then the main institutional and operational innovations and tools through which ASEAN is preparing to deal with disaster risk are explored. Finally, the article suggests that despite ASEAN overall institutional innovations, the practice of cooperation still is effected by several factors, above all the lack of adequate resources and the difficulty of reconciling principles of solidarity with national sovereignty, which hinder ASEAN effectiveness in this area.  相似文献

Do natural disasters prolong civil conflict? Or are disasters more likely to encourage peace as hostilities diminish when confronting shared hardship or as shifts in the balance of power between insurgents and the state hasten cessation? To address these questions, this study performs an event history analysis of disasters’ impact on the duration of 224 armed intrastate conflicts occurring in 86 states between 1946 and 2005. I contend that natural disasters increase conflict duration by decreasing the state’s capacity to suppress insurgency, while reinforcing insurgent groups’ ability to evade capture and avoid defeat. First, disasters’ economic impact coupled with state financial outlays for disaster relief and reconstruction, reduce resources available for counterinsurgency and nation building in conflict zones. Second, the military’s role in administering humanitarian assistance can reduce the availability of troops and military hardware for counterinsurgency, prompt temporary ceasefires with insurgents, or both. Third, natural disasters can cause infrastructural damages that disproportionately hinder the state’s capacity to execute counterinsurgency missions, thereby making insurgent forces more difficult to capture and overcome. The combination of these dynamics should encourage longer conflicts in states with higher incidence of disaster. Empirical evidence strongly supports this contention, indicating that states with greater disaster vulnerability fight longer wars.  相似文献

This article investigates gender dimensions of decision-making on access to, and control over, productive assets for agricultural development in selected communities in Ghana. The men were more educated, resourced, and economically empowered than the women. This resulted in differential access to, and control over, resources by gender and a low level of female participation in decision-making. The study identified a land access gap by gender and crop acreage gap of up to 80% for women as compared to men. Challenges limiting women in agricultural production and processing include inadequate land access, inadequate capital, inefficient processing technologies, and unattractive markets.  相似文献

Traditional top-down approaches to community development reinforce nos/otros binaries within provider/recipient relationships; transcendent approaches, on the other hand, create space for nosotros collaborative development. This article describes an instance of the nos/otros binary, in which a foreign volunteer in a rural community in Ecuador assumed the role of practitioner and limited community members’ roles to recipients or beneficiaries of her development projects. Inspired by findings from this experience, the article presents a case study highlighting an alternative, transcendent, nosotros approach in Albuquerque, New Mexico, where community members work together to imagine, implement, and sustain projects.  相似文献

A significant part of urbanisation in India is happening through unregulated or partly regulated trajectories that are either informal or semi-formal in nature, and regulatory authorities have come to terms with them on a piecemeal basis over a period of time. This article contends that what is considered unplanned by regulatory agencies is actually planned by people and facilitated by the normativity surrounding both formal and informal institutions of urbanisation in society. The study looks at the processes through which such a housing settlement comes into being and negotiates legitimacy, authorisation, as well as basic civic services.  相似文献

Two cases of fatal intoxications with toluene due to glue sniffing are described. In case 1, the autopsy did not indicate cause of death, while in case 2, the cause of death was determined to possibly be due to mechanical asphyxia by drowning. As the decedents had a history of glue sniffing, toxicological analyses were performed. Using gas chromatography with flame ionization detector and gas chromatography/mass spectrometry (GC/MS) with headspace method, toluene was detected in biological samples. Toluene ranged from 3.81 to 20.97 μg/g, with the highest concentrations observed in liver and brain (13.82–20.97 μg/g) in both cases. Based upon this data, the cause of death in both cases was determined to be toluene poisoning. Toxicological investigations are extremely important and should be considered mandatory in all deaths thought to be due to volatile substance abuse, as well as all deaths that are thought to be due to poisoning in young people.  相似文献
