International Co‐Authorship and Research Team Performance in Colombia

This article examines the ways in which International Scientific Collaboration, as observed by the co‐authorship of journal articles written by local scientists and partners located overseas, affects the ability of research teams to produce bibliographic outputs and to contribute to local knowledge. A sample of 672 teams was randomly selected for the analyses. In addition, 20 interviews with experts and team members were administered to discuss models and results. Results show that co‐authoring with partners located overseas increases team output by nearly 40% and by between three and five bibliographic products. It also shows that a team's odds of involving Colombia in its research process are 2.2 times larger for those co‐authoring with a partner located overseas than for those that do not. Theoretical and policy implications are discussed.

Legal production of illegality in a comparative perspective. The cases of Malaysia and Spain

Most studies on illegal migration focus on particular national or local settings and most theoretical approaches are built upon research done in America and Western Europe. In consequence, there is little understanding about the legal construction of the ‘illegal’ and the meanings of migrants’ illegality in different political contexts. Given these major shortcomings, this article compares the cases of Malaysia and Spain. By comparing how we can explain illegal immigration and what it means to be illegal in each country, the final aim of this article is to place the term ‘illegal’ back into its context, that is, to understand the ‘illegal’ not as an essentialised, generic and singular object but rather as a legal and political product of particular historical and national contexts.     

论《大学》的道德修养体系

《大学》是早期儒家的一篇结构严谨,体系完整的典籍,与《中庸》、《论语》、《孟子》并称四书,且居四书之首。《大学》的主要内容是“三纲领”和“八条目”,二者是《大学》的两条基本道德修养原则,且构成了以修身为核心的一个互为对应的整体。《大学》围绕“三纲八目”构建了一套修己治人的道德修养体系,同时也蕴含了儒家的内圣外王之道。     

Maize diversity,poverty, and market access: lessons from Mexico

Crop genetic diversity and poverty are linked: first, resource-poor farmers often maintain genetic diversity; and second, crop diversity, when properly valued by the market, has the potential to alleviate poverty. This article examines this supposition by drawing on three case studies of the intersection of the market with poverty and maize diversity in Mexico. These suggest that the bulk market for maize offers little room for maize landraces (local maize varieties known as criollo maize), in that it does not reward qualitative variation in maize grain and instead presents incentives that make planting ‘improved’ maize germplasm the rational economic choice for small-scale farmers. Meanwhile, attempts to add value to maize landraces via market differentiation have had varying success. Although there is potential for differentiated markets to contribute to successful business models and poverty alleviation, these cases exhibit trade-offs between product consistency, investment of labour and resources, and genetic-diversity conservation.     

The Geography of Repression and Opposition to Autocracy

State repression is a prominent feature of nondemocracies, but its effectiveness in quieting dissent and fostering regime survival remains unclear. We exploit the location of military bases before the coup that brought Augusto Pinochet to power in Chile in 1973, which is uncorrelated to precoup electoral outcomes, and show that counties near these bases experienced more killings and forced disappearances at the hands of the government during the dictatorship. Our main result is that residents of counties close to military bases both registered to vote and voted “No” to Pinochet's continuation in power at higher rates in the crucial 1988 plebiscite that bolstered the democratic transition. Potential mechanisms include informational frictions on the intensity of repression in counties far from bases and shifts in preferences caused by increased proximity to the events. Election outcomes after democratization show no lasting change in political preferences.     

Development and validation of a liquid chromatography-mass spectrometry assay for hair analysis of methylphenidate

Examination of various SIM cards and smart card devices indicates that data may be retained in SIM card memory structures even after heating to temperatures up to 450 degrees C, which the National Institute of Standards and Technology (NIST) has determined to be approximately the maximum average sustained temperature at desk height in a house fire. However, in many cases, and certainly for temperatures greater than 450 degrees C, the SIM card chip has suffered structural or mechanical damage that renders simple probing or rewiring ineffective. Nevertheless, this has not necessarily affected the data, which is stored as charge in floating gates, and alternative methods for directly accessing the stored charge may be applicable.     

Parentage testing on blood crusts from firearms projectiles by DNA typing settles and insurance fraud case

We describe a case of a fraudulent insurance claim. The family of an adult white male (DLF) notified the police of their son's disappearance. After a few weeks, a corpse that presented characteristics similar to those of the DLF was found in advanced stages of decay and was identified by the family as being DLF. The family then filed a claim for the life insurance that DLF had taken out just before he disappeared. Suspicions were raised about the identification of the corpse, because it had been done only visually, and because the insurance policy had been taken out just prior to DLF's disappearance. The insurance company requested a postmortem examination for identification. As the corpse had been cremated immediately after identification by the family, the biological material that was encrusted on the two projectiles removed from the body was used for analysis. The blood crusts provided enough genomic DNA for us to carry out PCR base typing of HLA-DQA1, D1S80, HUMCSF1PO, HUMTPOX, HUMTH01, D3S1744, D12S1090, D18S849, and amelogenin. Results from all loci typing from the corpse presumed to be that of DLF were then compared with that of his alleged biological parents, revealing genetic incompatibility.     

Unexpected sudden death from coronary sinus thrombosis. An unusual complication of central venous catheterization

Coronary sinus thrombosis is an unusual but potentially serious complication of the use of central venous devices. We report a fatal case of coronary sinus thrombosis in relation to a malpositioned central venous catheter. The death occurred very soon following the beginning of symptoms and the cause could not be suspected. Direct trauma of the catheter on the coronary sinus endothelium seems the most probable cause of the thrombosis.
