Novel psychoactive substances (NPS) are synthetic drugs that pose serious public health and safety concerns. A multitude of NPS have been identified in the United States, often implicated in forensic investigations. The most common and effective manner for identifying NPS is by use of mass spectrometry and the true utility lies within nontargeted acquisition techniques. During this study, a liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) assay was developed, validated, and implemented for forensic toxicology testing. A SCIEX TripleTOF™ 5600 + with SWATH® acquisition was used. Resulting data were compared against an extensive library database containing more than 800 compounds. The LC-QTOF-MS assay was applied to the reanalysis of biological sample extracts to discover emergent NPS. More than 3,000 sample extracts were analyzed, and more than 20 emerging NPS were detected for the first time. Among these were isopropyl-U-47700, 3,4-methylenedioxy-U-47700, fluorofuranylfentanyl, N-methyl norfentanyl, 2F-deschloroketamine, 3,4-methylenedioxy-alpha-PHP, eutylone, and N-ethyl hexedrone. 相似文献

This article aims to assess the role of important socio-economic factors in the family history of tuberculosis patients in Pakistan. Data were collected from 269 patients, and a logistic regression was used to determine the association between risk factors and the vicious circle of TB. Results of the logistic model show that significant risk factors associated with TB history in patients were education, household size, house structure, rooms in the home, room ventilation, monthly income, income food sufficiency, smoking, diabetes, and heart disease. The current TB control programme needs to formulate strategies to target specific risk factors and poverty reduction simultaneously to break the vicious circle of tuberculosis. 相似文献

International development agencies, with the help of the central government, support building state of art Bus Rapid Transit (BRT) in low-income Asian cities. However, BRT investment over indigenous modes of mobility is creating socio-political tensions at the local level. This article uses multi-level governance as a theoretical lens to examine the relationships among actors in BRT investment decisions in Bandung and Surabaya, Indonesia. The research finds that local stakeholders can distort national and supranational policy initiatives totally or in a way that while projects are delivered, they are of limited use to the local communities they intended to help. 相似文献

This article analyses welfare impacts of fertiliser adoption using data collected from 838 cocoa farm households in the four key cocoa-producing regions in Ghana. Using propensity score matching (PSM), the study indicates that application of fertiliser leads to significant gains in farm yields, farm income, consumption expenditure, consumption expenditure per capita, and value of productive farm assets. The article concludes that cocoa-specific programmes such as Cocoa High Technology (Cocoa Hi-tech), initiated to intensify the application of improved farm technologies such as fertiliser, should be strengthened through effective and efficient management systems. 相似文献

International development NGOs are in existential crisis. Their legitimacy and added value are increasingly challenged. While scholars have focused on legitimacy, work on “value-added” is scarce. In particular, no research addresses the value of domestic programmes to international NGOs. This article rectifies this, focusing on the case of Oxfam GB’s UK Poverty Programme (UKPP). Using empirical research from 35 interviews with Oxfam GB staff, partners and beneficiaries and over 150 archive documents, the article identifies seven assets through which the programme provides value added to Oxfam GB. It highlights the possibility that these could offer insights into the dimensions of future INGOs. 相似文献

This article investigates trust among dairy value-chain actors to understand the innovative process in a local productive sector in Tunisia. It uses a sample of 45 smallholder farmers chosen randomly nearby existing collection centres in the region. A trust variable is constructed employing 11 ordinal variables based on principal component analysis, and institutional arrangements then modelled to examine the effect of trust on contracting decisions and cooperative membership. The results show that trust is defined by values such as “integrity”, “competence”, and “existence of credible information”, which are preconditions to sustainable contracts. The article contributes to the growing literature which considers social capital, networking and trust as determinants of farmer’s behaviour, as opposed to the classical model of rationality. 相似文献

In the recent past, governance reforms in India have resulted in the government and corporate sectors making serious efforts to enhance and showcase their accountability to their principals, namely citizens and shareholders. Similarly, NGOs have been pushed to demonstrate their accountability to multiple stakeholders, namely donors, communities and most importantly, the state. This viewpoint highlights this transition and also reflects on the changing contours of NGO accountability debates in India. 相似文献
