This article examines the use of North Korean defectors’ accounts as a source of information for studying the Democratic People’s Republic of Korea (DPRK). Information from defectors fills a vital knowledge gap and improves our understanding of North Korean politics, economics, and society. Witness accounts and interview data collected from people who were born in North Korea but have since left have been widely used by journalists, government agencies, international organizations, non-governmental organizations, and academics. There are, however, serious methodological issues in collecting, organizing, and interpreting information derived from defectors’ accounts. Selection and demographic biases, power relations between researchers and interviewees, monetary incentives, and language barriers are among those issues. We propose focus group discussions and participatory observation as complementary methods of data collection to mitigate the shortfalls of relying on individual interviews.  相似文献

ABSTRACT

Historical writing in Tanzania has had highly serious goals from the early days of the history department at the University of Dar es Salaam. Historians have aimed at the decolonization of intellectual life, the construction of a national historical identity, and the achievement of a just society. This body of well-contextualized historical writing has circulated widely within the country, but does not reach readers outside east Africa as fully as it deserves. The article explores parallels with African genomic science as a way of getting at inequalities between northern and southern countries in access to resources for academic research and publication.  相似文献

We distinguish between (i) voting systems in which voters can rank candidates and (ii) those in which they can grade candidates, using two or more grades. In approval voting, voters can assign two grades only—approve (1) or not approve (0)—to candidates. While two grades rule out a discrepancy between the average-grade winners, who receive the highest average grade, and the superior-grade winners, who receive more superior grades in pairwise comparisons (akin to Condorcet winners), more than two grades allow it. We call this discrepancy between the two kinds of winners the paradox of grading systems, which we illustrate with several examples and whose probability we estimate for sincere and strategic voters through a Monte Carlo simulation. We discuss the tradeoff between (i) allowing more than two grades, but risking the paradox, and (ii) precluding the paradox, but restricting voters to two grades.  相似文献

There has been a significant shift in government towards decentralized power and responsibility as exemplified by the State and Local Assistance Act. The trend occurs at a time when society faces the double challenge of encouraging more and better informed, public participation in decision-making, and also improving the efficiency in governmental delivery of services. A proposal is made to use general revenue sharing moneys to meet this dual challenge through a revenue sharing voucher program (RSVP). The program entails turning back to citizens the incoming funds in the form of vouchers to be allocated by them to various local government agencies. The implications for the City of Seattle are discussed as an example of the operation and the tradeoffs involved.  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

In this short piece, I set out briefly what we know about the challenge of diversity in the legal academy from existing scholarship. That field, in the UK at least, is sparse. I then go on to present a snapshot of the legal academy using data from the Higher Education Statistics Agency (HESA). I do this as the start of a much larger project on diversity and the legal academy that I plan to undertake over the next year. My argument is rather simple. The diversity of the legal academy reflects neither the diversity of our law student bodies nor the diversity of the wider population. Such diversity is vital for a number of reasons. My hope is that this piece can be the start of a dialogue on an important and largely ignored topic, and that further research will be done in this area.  相似文献
