Disasters such as flash flooding, mass shootings, and train and airplane accidents involving large numbers of victims produce significant opportunity for research in the biosciences. This opportunity exists in the extreme tails of life events, however, during which decisions about life and death, valuing and foregoing, speed and patience, trust and distrust, are tested simultaneously and abundantly. The press and urgency of these scenarios may also challenge the ability of researchers to comprehensively deliver information about the purposes of a study, risks, benefits, and alternatives. Under these circumstances, we argue that acquiring consent for the immediate use of data that are not time sensitive represents a gap in the protection of human study participants. In response, we offer a two-tiered model of consent that allows for data collected in real-time to be held in escrow until the acute post-disaster window has closed. Such a model not only respects the fundamental tenet of consent in research, but also enables such research to take place in an ethically defensible manner.  相似文献

In 2013, the Laos Ministry of Education and Sports (MoES) commissioned a mid-term review of the Education Sector Development Plan 2011–2015 (ESDP, Lao People's Democratic Republic, Ministry of Education and Sports 2010). Plan International, a United Nations Girls Education Initiative partner, worked with MoES to lead a gender audit for the mid-term review. The gender audit strengthened the mid-term review and contributed to the design of the new ESDP. A MoES gender and inclusion working group was established, providing an institutional structure to support focused policy dialogue and address recommendations. This note recommends the inclusion of gender audits within mid-term reviews and final evaluations of sectoral plans to ensure that investments adequately address gender equality.  相似文献

In forensics, bloodstains on dark fabrics might be invisible for the naked eye. Although several visualization, presumptive, and confirmatory blood tests have been developed, all have one or more disadvantages, especially on DNA analysis. We report here the use of a visualization assay that can visually detect blood drops up to 1/20 dilution. In this assay, the fabric is placed between two wet filter papers and covered by glass surfaces on both sides. Pressure is applied on the glass surfaces in which bloodstains transfer onto the filter papers through capillary forces. Detected stains can be tested with other more sensitive presumptive blood tests performed on the filter paper. Even more, DNA analysis can be performed on the transferred bloodstains. The presented visualization assay is easy to perform, extremely cheap, requires little hands on time, and does not affect bloodstain pattern analysis.  相似文献

This article addresses the vagueness, and the interpretative challenges associated with, international investment agreements (IIAs) and develops a new normative framework for interpreting these treaties. It focuses on the historical embedding of investment protection as a means of facilitating economic development as well as upon its synthetic public law nature. The analysis shows that a teleological approach to interpretation imposes boundaries on the meaning of substantive IIA provisions. The article then elaborates how the transnational dimension of IIAs provides a benchmark, which is the level of protection offered to economic actors against interference by the state in countries with the highest rule of law standards. The article then shows how the resulting challenges of comparative public law could be addressed through the methodology of re‐ and pre‐statement of transnational uniform ‘principles’: sophisticated and detailed rules striking the proper balance between private economic interests and the public regulatory interest, so as to provide more legal certainty for both investors and host states.  相似文献

Immigrants and their descendants are becoming increasingly visible in Germany’s political life. What determines immigrant political incorporation into parliamentary positions over time and in specific contexts? The article focuses on the regional parliaments of Germany’s 16 states. A comparative analysis enables us to specify whether, how and under what conditions factors thought to impact levels of immigrant representation are indeed influential and how they interact with local and situational conditions. The article first outlines immigrant representation in Germany’s states over time. It then discusses several possible explanations for the striking variation between states. Rather than one key factor, it is found that interactions between demographic, institutional, cultural and political conditions account for different levels of immigrant representation in Germany’s state parliaments.  相似文献

Scholars of regions where multiple languages are spoken have much to gain by considering heritage language education, individual identity, and state power through these ethnographic and historical cases that focus on Japan and the Japanese diaspora. The articles in this two-part collection offer insights into the interrelationships of linguistic hierarchies and political economy, the navigation of ethnic and racial subjectivities, and the ways children and adolescents claim belonging to various communities through their linguistic practices. The articles interrogate not only heritage but remembrance and the ways individuals may produce identity through language in everyday interactions and institutional settings.  相似文献
