Analysis of the CODIS autosomal STR loci in four main Colombian regions

Genotype polymorphism studies at the 13 loci STRs included in the combined DNA index system [CODIS and PCR-based short tandem repeat loci, in: Proceedings of the Second European Symposium on Human Identification, Promega Corporation, Madison, WI, 1998, pp. 73-88; J. Forensic Sci. 46 (2001) 453] (CODIS: D3S1358, HUMvWA31, HUMFGA, D8S1179 D21S11, D18S51, D5S818, D13S317, D7S820, HUMTH01, HUMTPOX, HUMCSF1PO and D16S539) were carried out in a sample of 1429 unrelated Colombian individuals belonging to 25 different departments. As many other countries in Latino-America, Colombia shows an important admixture component, basically integrated by Amerindians, European-descendants and African-descendants. Due to the fact that only partial population analyses have been carried out in the country, the main aim of the present analysis is to establish a database of forensic interest based on the widely used CODIS systems covering the main Colombian regions.     

Using Cluster Analysis and ICP‐MS to Identify Groups of Ecstasy Tablets in Sao Paulo State,Brazil

The variations found in the elemental composition in ecstasy samples result in spectral profiles with useful information for data analysis, and cluster analysis of these profiles can help uncover different categories of the drug. We provide a cluster analysis of ecstasy tablets based on their elemental composition. Twenty‐five elements were determined by ICP‐MS in tablets apprehended by Sao Paulo's State Police, Brazil. We employ the K‐means clustering algorithm along with C4.5 decision tree to help us interpret the clustering results. We found a better number of two clusters within the data, which can refer to the approximated number of sources of the drug which supply the cities of seizures. The C4.5 model was capable of differentiating the ecstasy samples from the two clusters with high prediction accuracy using the leave‐one‐out cross‐validation. The model used only Nd, Ni, and Pb concentration values in the classification of the samples.     

“We don’t want to hear about discrimination”: Evidence slippage and evidence invention in the politics of foreign credential recognition in Canada

This article investigates how Canadian politicians engaged with evidence on foreign credential recognition in 2009. We find that some evidence receives decreasing attention over time, that some politicians bring forward explanations that have nothing to do with the evidence, and that most politicians hold the same position before and after the process of evidence‐gathering. These findings cast doubt on the extent to which politicians use evidence to inform their position on immigration‐related issues, even when they explicitly solicit it.     

Business cycle and political election outcomes: Evidence from the Chilean democracy

This paper explores the influence of economic variables in Chilean presidential elections. We use a panel where the dependent variable corresponds to the share of the vote obtained by the incumbent at a municipal level in the presidential elections of 1989, 1993 and 1999. We focus on the unemployment rate and the output gap and find that both have a significant influence on the vote. We also find that if the mayor is from the same coalition as the incumbent, people will further punish the incumbent when regional unemployment is above national unemployment.     

Imaginaries of the Pandemic in Chile: A Conceptual-Empirical Discussion

This article aims to reconstruct the social imaginaries of Coronavirus disease 2019 (COVID-19) in Chile. We seek to understand how families interpret their experience confronting the pandemic by identifying four main aspects: (a) the COVID-19 pandemic, (b) working and learning, (c) health and (d) family life. Following Habermas' distinction between lifeworld and social systems, we consider these issues as constituting the social imaginary of lifeworld, different but related to the imaginaries of social systems. The qualitative empirical data was gathered through a sample of 38 families interviewed online between September 2020 and January 2021 in four Chilean cities: Iquique, Valparaíso, Santiago and Concepción. Other complementary sources of information are multimodal ethnography (digital diaries), press articles and state reports.     

The political cost of public–private partnerships: Theory and evidence from Colombian infrastructure development

Infrastructure public–private partnerships (PPPs) eschew traditional public management to provide distributive goods worldwide. Yet, in Colombia, the context of our study, both the promise of and voters' experience with PPPs hinder incumbent parties in elections when theories of distributive politics expect otherwise. We argue that negative experiences with PPPs introduce a sociotropic turn in individual voting: bad experience crowds out the possibility that promising a new project will improve a voter's own welfare. Studying what are, to our knowledge, all 109 Colombian PPP projects between 1998 and 2014, and over 8,700 individual survey responses, our evidence shows that vote intention for the incumbent executive or his party decreases as experience with more PPPs in respondents' districts increases. Our analysis and results introduce an important agenda for research into the political significance of these legacies of new public management.     

Assessing the credibility of how climate adaptation aid projects are categorised

This article presents the findings of a re-evaluation of all 5,200 aid projects that OECD donors reported for 2012 as “climate change adaptation”-related, based on the “Rio marker” classification system. The findings confirm those from the academic and grey literature that the absence of independent quality control makes the adaptation Rio marker data almost entirely unreliable. This lack of credibility impedes meaningful assessments of progress toward the mainstreaming of adaptation in development cooperation activities. It also erodes trust in international climate negotiations, given that these data are frequently used in the financial reporting of developed countries to the UNFCCC.
