Environmental conditions associated with shark attacks against humans: a case report about territoriality

This article describes the autopsy findings of a victim of a shark attack that took place off the coast of Pernambuco, Brazil. The victim was rescued and immediately taken to a nearby hospital but did not survive, even though the lapse of time between the attack and verification of death did not exceed 15 minutes. The presence of a single, large, contused and incised, semiarched wound with a serrated aspect was decisive in elucidating the event. Thus, this study discusses aspects related to the aggressor species, to the autopsy, to the type of wound, and to the causes that have led to a significant increase in this type of event in the area. It was concluded that the lesion was produced while the victim was still alive and that it was the cause of death.     

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.     

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.     

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.     

Postmortem vitreous humor beta-hydroxybutyrate: its utility for the postmortem interpretation of diabetes mellitus

Ketoacidotic coma is one of the most serious complications arising from diabetes mellitus, especially type I, and may be the cause of sudden death especially in diabetes type I. Since beta-hydroxybutyrate (beta-OHB) serum concentrations might provide more information on the severity of ketoacidosis, the aim of this study was to evaluate the concentrations of beta-OHB in vitreous humor and its correlation with other biochemical parameters during postmortem examination. We intended to ascertain the sensitivity and the specificity of these markers for diagnosing diabetes mellitus and the presence of ketoacidosis. This study involved 453 cadavers with a mean age of 57.6 years (S.D. 20.7) and a mean postmortem interval of 17.8 h (S.D. 9.6, range 2-61 h). Cases were assigned to two diagnostic groups according to the antemortem diagnosis of diabetes mellitus, based on the patients' medical records. In vitreous humor statistically significant differences were found in biochemical marker concentrations between the two diagnostic groups, the highest values being obtained in the group of subjects with a previous diagnosis of diabetes mellitus. The measurement of beta-OHB in vitreous humor may be a useful alternative to using blood during postmortem analysis. The presence of high levels of beta-OHB may help interpret the cause of death in diabetics when the autopsy result is negative.     

Institutional Context, Cognitive Resources and Party Attachments Across Democracies

e-mail: jdh39{at}columbia.edu e-mail: gck2001{at}columbia.edu e-mail: ell2002{at}columbia.edu This paper develops and tests arguments about how national-levelsocial and institutional factors shape the propensity of individualsto form attachments to political parties. Our tests employ atwo-step estimation procedure that has attractive propertieswhen there is a binary dependent variable in the first stageand when the number of second-level units is relatively small.We find that voters are most likely to form party attachmentswhen group identities are salient and complimentary. We alsofind that institutions that assist voters in retrospectivelyevaluating parties—specifically, strong party disciplineand few parties in government—increase partisanship. Theseinstitutions matter most for those individuals with the fewestcognitive resources, measured here by education.     

Just war and the Lebanese resistance to Israel

The literature on Lebanese resistance to Israel is overwhelmed with work on Hezbollah, the role of religion, and its connection to Iranian influence. However, few of these studies have looked at the totality of Lebanese resistance, from its secular origins to its Islamic monopoly. Moreover, no work to date has looked at Lebanese resistance through the prism of just war theory. This article aims at addressing this gap by applying the criteria introduced by Childress regarding the justness of war. Moreover, the article examines resistance as a practice of non-state actors and its terrorist label, and at the same time, evaluates Israel’s military response to Lebanese resistance through the prism of state terrorism.
