Expanding housing choices for the sector popular: Strategies for Mexico

Abstract

By the year 2000, some 40 million people in Mexico will live in settlements commonly called the informal sector. Most will live in houses that they have constructed themselves and that have some infrastructure deficit. To meet their needs, the authors propose a set of demand and supply strategies. Emphasis is placed on the increased use of small group savings programs, the provision of progressive infrastructure, and the creation of housing‐related employment. The supply of low‐cost land must be increased, which will necessitate reforms in the ejido land tenure system. Examples of locally derived, non‐government‐supported betterment programs are presented.

The article concludes by calling on the federal government to create stronger links with the informal sector and to reestablish its role as the supporter of social housing in Mexico.     

Institutional impact of criminal networks in Colombia and Mexico

This paper explores the effects of criminal networks involved in corruption and drug trafficking on democratic formal institutions in Colombia and Mexico. The theoretical framework is sustained in the concepts of State Capture (StC) and Co-opted State Reconfiguration (CStR). Three illicit networks are analyzed: (i) The Familia Michoacana in Mexico, (ii) the Autodefensas Campesinas del Casanare (ACC) in Colombia and (iii) the Autodefensas Unidas de Colombia (AUC). These cases are analyzed throughout the Social Network Analysis (SNA) in order to identify (i) the hub and (ii) the structural bridge of each network. A methodological variation referenced as Social Network Analysis for Institutional Diagnosis (SNAID) is also applied, in order to analyze the institutional scope of processes of StC and CStR. Conclusions and explorative venues regarding the application of SNA and SNAID as a diagnosis tool are presented.     

Analysis of 2,4-Dinitrophenol in Postmortem Blood and Urine by Gas Chromatography–Mass Spectrometry: Method Development and Validation and Report of Three Fatalities in the United States

2,4-dinitrophenol (2,4-DNP) is a compound used in the early 1900s as a weight-loss drug but later prohibited due to its severe adverse effects, including death. It has however been attracting interest, due to its weight-loss properties, and appears to be re-emerging in forensic casework. As 2,4-DNP is available for use in industry and as a pesticide and easily accessible online, the dissemination of this drug can be fast. The compound exerts its effects through inhibition of ATP synthesis, and corresponding thermogenic energy loss which can be fatal. A method for qualitative and quantitative analysis of 2,4-DNP in blood and urine specimens using GC-MS with hydrogen as carrier gas is described. The method was validated and displayed acceptable performance parameters with linearity (R² higher than 0.998), inter-assay imprecision (lower than 10.6%), intra-assay imprecision (lower than 10.7%), and extraction efficiency (92.1%). Stability of 2,4-DNP in blood and urine was studied, and the drug was stable up to 30 days refrigeration or frozen. Six cases in United States suspected to be related to 2,4-DNP were analyzed. Three cases were found to be positive for 2,4-DNP. Concentrations of 2,4-DNP were in the range of 61.6–220 mg/L in urine and <3–114 mg/L in blood. Based on our findings, we suggest that medical examiners and forensic toxicologists be aware of the reappearance of 2,4-DNP, including this compound as a target in death investigations related to weight-loss drugs.     

Bureaucratic incentives, path dependence, and foreign aid: An empirical institutional analysis of irrigation in the Philippines

At least 25 developing countries are embarking on irrigation governance reforms to address the persistent problem of poor irrigation performance. Some scholars suggest that the patterns of construction, deterioration, rehabilitation, and modernization commonly found among irrigation agencies in these countries are rational because of the time inconsistency problem of information. I argue instead, using panel data from the Philippines, that the problem of poor performance is linked to inherent incentive problems faced by public bureaucracies, how these incentives became entrenched in the path dependence of irrigation development, and how these were reinforced by incentives embedded in irrigation aid, particularly by the moral hazard problem and the fungibility of irrigation aid.     

Selling Sustainable Development and Shortchanging Social Ecology in Costa Rican Forest Policy

Costa Ricans have worked hard to weave the norms and principles of sustainable development into their nation's environmental policies, especially with respect to natural renewable resources, such as the forest. As a result, the nation is known as a leader in innovative environmental initiatives. But sustainable development is a complex, evolving concept. This paper analyzes how the emphasis on biodiversity conservation during the 1990s and early 2000s has, rhetoric notwithstanding, neglected the social equality, or livelihood, component of sustainable development. This trend stands in sharp contrast to earlier periods, when decisionmakers crafted policies and institutions that supported social ecology. The article concludes with a few observations on building political will to revive the grassroots development component of sustainable development.     

Y chromosome microsatellite genetic variation in two Native American populations from Argentina: Population stratification and mutation data

Two Native American populations from North and northwest regions of Argentina (Toba and Colla) were analyzed for 17 Y chromosome short tandem repeat loci (Y-STRs), namely, DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 and GATA H4.1. Over 357 allele transfers, two one-step mutations could be detected at DYS456 and GATA H4.1 loci. A new 16.1 ‘micro-variant’ allele was observed for DYS385, characterized by an insertion at the fifth GAAA repeat. We also observed two alleles at the DYS448 locus in three samples (two from Toba and one from Colla). A total of 34 and 16 different haplotypes were detected for Toba and Colla, respectively, the former with a haplotype diversity value of 0.9769 ± 0.01, whereas 0.9497 ± 0.02 for the latter. Significant population differences were observed between Colla and Toba, at least in part, due to a more prevalent European input in the Colla. In agreement with this observation is the fact that the genetic distances between Colla and Iberian populations are lower than those observed between Iberian and any other Native American population. The results of multiscaling dimensional analysis and genetic distances (Rst) among Native American population samples also reflect this fact. The data show the existence of clear population stratification in the Argentina, a fact that should be taken into account in forensic casework.     

The sexual objectification of girls and aggression towards them in gang and non-gang affiliated youth

Sexual objectification is related to various negative attitudes and outcomes, including rape proclivity and reduced moral concern for the objectified, which suggests that objectification has implications for aggression. Our study examined the relationship between objectification and general aggressive behaviour in adolescents, including gang-affiliated youth. We hypothesized that (1) objectification would correlate with aggression towards girls, (2) gang affiliation would correlate with objectification and aggression towards girls, and (3) objectification and gang affiliation would interact such that strongly affiliated participants who objectified girls would be most aggressive towards them. We also hypothesized that sexual objectification would be a significant predictor of aggression above and beyond other factors, such as trait aggression. As predicted, objectification correlated with aggression towards girls and with gang affiliation, which also correlated with aggression. In addition, objectification predicted aggression towards girls, after controlling for other relevant factors. Further, we found an objectification?×?gang affiliation interaction, which differed from our original predictions. Among participants low in gang affiliation, objectification of girls predicted levels of aggression towards them. Among those high in gang affiliation, however, objectification did not predict aggression. We discussed the implications of our findings for general aggression.     

Varieties of vigilantism: conceptual discord,meaning and strategies

The practice of vigilantism raises a number of broader provocative questions regarding state–society relations. But before pursuing these questions, we must first ask a critical conceptual question: what is vigilantism? In this article, I offer a conceptual analysis of vigilantism to identify and analyse the points of conceptual discord that make vigilantism an essentially contested concept. To address these challenges, I establish the concept’s core definitional dimensions and range of attributes. I then develop a root concept of vigilantism as the collective use or threat of extra-legal violence in response to an alleged criminal act. The root concept better positions researchers to effectively utilise different strategies to amend the concept for varying theoretical and empirical ends, avoid analytical pitfalls that beset existing conceptualisations and pursue promising new research questions.     

Using an evolutionary perspective to understand the relationship between physical aggression and academic performance in late adolescents

In this study, we applied an evolutionary perspective to analyze the relationship between aggressiveness, academic performance, and sociality in a population of 528 adolescents of both sexes. In men, we expect physical aggression (PA) and sociality to be negative predictors of academic performance. However, in women, PA would be a negative predictor of academic performance, and sociality a positive one. Our results report a negative association between academic performance and PA in both sexes. As we expected, social effect derived from the use of PA seems to be different for each sex, where men could display a rebellious attitude to increase chances of finding a mate. In contrast, results for women are not conclusive, because no relationship between academic performance and any aggressive mechanism, were predicted by sociality. We conclude that an evolutionary framework, which includes sex-specific hypotheses, is appropriate to obtain a holistic perspective of this phenomenon.
