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. 相似文献

In the context of the COVID-19 pandemic, governments around the world have implemented exceptional measures aimed at restricting people's mobility or banning public spaces used, among other things, for protest, thus causing the expected regressive effects in the socioeconomic sphere. What happens with social protest when the public space is banned? Does it stop, is it displaced, does it occur in any other form? In this article we present a map of protest in Argentina since the beginning of the pandemic. We conclude that the levels of participation remain high and that, given the features of the protest itself, its claims may be channelled into the institutions. 相似文献

Diverse sources have constructed a common narrative of individual and isolated responses by countries and their leaders to the global coronavirus pandemic, akin to sálvese quien pueda (every man for himself). This article suggests that this is a simplification of the governance of the COVID-19 pandemic in Peru. Peru's governance story is one of domestic public and private action closely interwoven with crucial elements of transnational administration out of sheer necessity. The struggle against the pandemic has generated a domestic and transnational administrative symbiosis, involving authorities at multiple levels in efforts to fill a series of interconnected domestic, regional, and global governance gaps. 相似文献

The need for agile and proper identification of drugs of abuse has encouraged the scientific community to improve and to develop new methodologies. The drug lysergic acid diethylamide (LSD) is still widely used due to its hallucinogenic effects. The use of voltammetric methods to analyze narcotics has increased in recent years, and the possibility of miniaturizing the electrochemical equipment allows these methods to be applied outside the laboratory; for example, in crime scenes. In addition to portability, the search for affordable and sustainable materials for use in electroanalytical research has grown in recent decades. In this context, employing paper substrate, graphite pencil, and silver paint to construct paper-based electrodes is a great alternative. Here, a paper-based device comprising three electrodes was drawn on 300 g/m2 watercolor paper with 8B pencils, and its efficiency was compared to the efficiency of a commercially available screen-printed carbon electrode. Square wave voltammetry was used for LSD analysis in aqueous medium containing 0.05 mol/L LiClO4. The limits of detection and quantification were 0.38 and 1.27 μmol/L, respectively. Both electrodes exhibited a similar voltammetric response, which was also confirmed during analysis of a seized LSD sample, with recovery of less than 10%. The seized samples were previously analyzed by GCMS technique, employing the full scan spectra against the software spectral library. The electrode selectivity was also tested against 3,4-methylenedioxymethamphetamine (MDMA) and methamphetamine. It was possible to differentiate these compounds from LSD, indicating that the developed paper-based device has potential application in forensic chemistry analyses. 相似文献

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. 相似文献

Workers in the informal transport sector are often exposed to multiple forms of workplace violence, for instance by the police and their colleagues. Through a collection of rich ethnographic stories and using the concept of popular resistance, this article investigates how and under what conditions rickshaw drivers in Bogotá resist violence in their workplace. The results reveal that rickshaw associations have been essential in articulating acts of everyday resistance to the legal ban on this activity, such regulating routes, fees and stops. However, associations have created new forms of oppression, being labelled as mafia-like organisations, showing that resistance can also translate into new forms of domination. Contrary to the argument that everyday resistance is uncoordinated, this article shows that acts of everyday resistance can be organised by actors that switch between different individual and collective strategies. Thus, organisations can provide a framework to resist the law on an everyday basis. 相似文献

Women's movements made important contributions to ending the period of authoritarian rule in Latin America, but their participation in the reconstruction of democratic politics has been more limited than expected. This paper argues that the enormous influence exerted by technocratic elites in the democratization process in Latin America has represented an obstacle to the improvement of women's status in the region. Gender-biased assumptions and practices have been only partially addressed, in part because the policy-making process is under the control of economists, a professional group with a particularly unfriendly stand towards gendered analysis. It is suggested that reforms within economics may help in the task of making democracy more responsive to the demands of women. 相似文献

In this paper, we test the effect of three different criminal deterrence theory policy tools: criminal certainty, severity,
and celerity of punishment. Whereas most criminal deterrence studies in this field focus on the former two components of deterrence
theory, this study also examines the potential deterrent effect of the latter component. Using a time-series design with monthly
data, we estimate the effects of an increase in the threat of punishment for traffic offenses resulting from a general increase
in fines for traffic offenses, an increase in the probability of getting caught with a blood-alcohol concentration (BAC) level
outside the legal limits, and the enactment of an “on-the-spot” fine payment policy in Portugal. We find strong evidence to
support a severity effect. An increase in the statutory severity of sentence maxima for traffic violations leads to a decrease
in accident and injury rates—approximately an average 0.5 percent reduction in monthly accident and injury rates. Changes
in the BAC levels and the mandatory swift payment policy did not produce any convincing deterrence impact.

Hanging is one of the most frequent methods for suicides among young males. This report presents two cases of suicide by hanging on pylons carrying high-voltage power lines. The male victims suffered electrocution while committing suicide. Electrocution was the cause of death in both cases, however in one case blunt force injuries from hanging contributed to death. In these two cases hanging was the intentional method of suicide and it was followed by electrocution. The cases demonstrate that scene investigation, a detailed autopsy with histology, and amamnestic data are essential in the evaluation of suicides by hanging and that the determination of the cause of death remains a challenge in investigating such cases. 相似文献
