University technology transfer in China: a literature review and taxonomy

The Chinese university system is one of the world’s largest academic research performers and technology transfer is one of the system’s central roles. Academic interest in Chinese university technology transfer in both the West and China has increased in parallel. This review aims to outline what is known and evaluate the state of research about university technology transfer in China. To be comprehensive, uniquely this review considers the relevant journal articles in both English and Chinese languages. The major themes and methodologies used by authors are identified. The evolution of the literature, particularly those in Chinese from general discussions often with minimal citations to more empirically rigorous studies is documented. It is also shown that the English and Chinese language literatures have little overlap in terms of citations, thereby indicating that the two research communities are still largely disconnected. It is found that the sources of data have remained quite limited and the quantitative research is based almost entirely upon government statistics collected for administrative purpose. The concluding discussion suggests possible avenues for future progress in terms of developing new data sources and increasing the cross-fertilization of two research communities.     

The Effect of Police Use of Lethal Force on Murder Levels in American Cities Before and After Ferguson

We assess the effects of police use of lethal force on subsequent murders by victim race and armed status before and after the August 2014 death of Michael Brown in Ferguson, MO. We regress monthly murder levels on instances of police use of lethal force by race and armed status controlling for fixed effects, population, unemployment, and murders in the prior month using city-level data for 93 cities from 2013 to 2015. For 2013–2015, we find that a police lethal force incident predicts a 1.8% increase in murders 2 months following the incident. However, prior to Ferguson, a police lethal force incident increases murders by 4.5% (after 2 months) and we are unable to find any evidence of differential responses to police use of lethal force based on victim race. However, we find evidence of differential responses to police use of lethal force based on victim armed status. Post-Ferguson, police use of lethal force is associated with significant differential responses based on victim race. In addition, we see a shift in the aggregate-level response to police use of lethal force. Post-Ferguson, a police lethal force incident decreases the murder level by 3.8% 3 months following the incident. In addition, lethal force incident involving a non-black victim decreases the number of murders by 4.3% while an incident involving a black victim increases the number of murders by 2.1% (after a 2-month lag). Changes in policing following the events of Ferguson had a generally positive but uneven effect.     

刑事案件中陪审员对科学证据的期望-“CSI效应”神话的观念与现实

美国密歇根州沃什特瑙县抽样调查显示，陪审员对于提供给他们的科学证据抱有很高的期望；在所有强奸案件和依据间接证据定案的案件中，如果把科学证据作为被告人有罪的一个条件，陪审员对这种科学证据的要求很高；观看《犯罪现场调查》的陪审员与没有观看该电视剧的陪审员在这方面没有任何差别。韦恩县的研究结果表明，陪审员对于他们使用的技术越精通，他们对于控方在其案件中使用科学证据的期望就越高。在这两个地方的研究表明，陪审员对科学证据的期望和要求是大众文化广泛变革的结果，是大众媒体和诉讼参与人相信这种效应存在而培养起来的。     

The Ludwig Martens–Maxim Litvinov Connection, 1919–1921

Research began when the author realized that Antony Sutton had misidentified the author of a key document published in his Wall Street and the Bolshevik Revolution (1974). This article reports on the interception by federal agents of the document (a letter) brought from the Copenhagen office of Soviet diplomat Maxim Litvinov and intended for Kenneth Durant who was employed by Ludwig Martens, Lenin's unrecognized representative in New York City. Analysis of the letter revealed the true author and opened a research channel for learning more about the backgrounds of three Soviet agents: Bornett Bobroff, Nora Hellgren, and Wilfred Humphries.     

Another look at across-crime similarity coefficients for use in behavioural linkage analysis: an attempt to replicate Woodhams,Grant, and Price (2007)

Abstract

In the absence of physical evidence, investigators must often rely on offence behaviours when determining whether several crimes are linked to a common offender. A variety of factors can potentially influence the degree to which accurate linking is possible, including the similarity coefficient used to assess across-crime similarity. The current study examines the performance of two similarity coefficients that have recently been compared to one another, Jaccard's coefficient (J) and the taxonomic similarity index (Δ_s), using samples of two crime types, serial homicide (N=237) and serial burglary (N=210). In contrast to previous research, the results indicate that Δ_s does not significantly outperform J with respect to linking accuracy. In addition, both coefficients lead to higher levels of linking accuracy in cases of serial homicide compared to serial burglary. Potential explanations for these findings are presented and their implications are discussed.
