Violent behaviors in drug addiction: differential profiles of drug-addicted patients with and without violence problems

This study explored the prevalence of violent behaviors in patients who are addicted to drugs. A sample of 252 addicted patients (203 male and 49 female) who sought outpatient treatment was assessed. Information on violent behaviors, sociodemographic factors, consumption factors (assessed by the European version of the Addiction Severity Index [EuropASI]), psychopathological factors (assessed by Symptom Checklist-90-Revised [SCL-90-R]), and personality variables (assessed by Millon Clinical Multiaxial Inventory [MCMI-II]) was collected. Drug-addicted patients who were associated with violent behaviors were compared on all variables with patients who were not associated with violent behaviors. The rate of drug-addicted patients with violent behaviors in this sample was 39.68% (n = 100). There were significant differences between the numbers of patients who did and did not demonstrate violence on some variables. Patients with violence problems were younger than those without violence problems and were more likely to report having been a victim of abuse. Moreover, they were significantly more likely to have experienced an overdose and showed a significantly higher score on several EuropASI, SCL-90-R and MCMI-II variables. According to these results, patients with violence control problems present with both a more severe addiction and several comorbid problems. The implications of these results for further research and clinical practice are discussed.     

Analysis of the Effect of Cyclophosphamide and Methotrexate on Chrysomya megacephala (Diptera: Calliphoridae),

Forensic entomotoxicology investigates the effects of chemical substances in the development of scavenger insects and the reflection on estimating the minimum postmortem interval (PMI). To evaluate the impact of the chemotherapeutic drugs cyclophosphamide (CF) and methotrexate (MTX) on the postembryonic development of Chrysomya megacephala, controlled experiments were performed by rearing the larvae on spiked minced beef with different concentrations of these drugs. The results indicated that CF significantly decreased their developmental rate up to 28 h but had no significant effect on larval and adult sizes, survival rate, and sex ratio, whereas MTX decreased larval and adult sizes, survival rate, and there was a deviation in the expected sex ratio toward females in MTX‐exposed larvae but had no significant impact on developmental rate. These negative interference factors should be considered in cases of suspected death of people that have undergone chemotherapy.     

Contribution to the Development of Guidelines in the Analysis of Biological Evidence in Sexual Assault Investigations

This investigation intends to study materials and techniques used for biological evidence collection in sexual assault cases and is divided into two stages: in stage one, methods for biological evidence collection (the single swab (including three variants) and the “double swab technique”) were compared; in stage two, swabs’ component material was compared. The sampling was composed of 42 heterosexual couples who provided mock samples. The collection methods in which the whole swab is covered by evidence presented significantly better outcomes (p < 0.001), such as the “double swab technique.” Additionally, nylon swabs proved to present significantly better features regarding the capacity of sample elution, providing significantly higher amounts of DNA (p ≤ 0.034). This study provides guidelines for better collection of biological evidence regarding the collection method using a swab and the proper swab material to utilize.

From patronage politics to community deliberation: the recent experience of democratic school management in Brazil

The article discusses the limits and possibilities of school empowerment within education systems plagued by pervasive patronage politics. The analysis focuses on reform initiatives implemented by Brazilian sub‐national governments throughout the 1980s and 1990s to allow for the election of school principals by parents, teachers and students. Until the implementation of this reform, state and local authorities had relied on the school system as a source of patronage resources, and principals were nominated according to political criteria. The new system of democratic school management was expected to undermine this patronage‐based system and foster community participation in school decisions. The article relies on secondary evidence to assess the impact of school elections in what concerns the participation of parents, students and teachers in school affairs and the relationship between schools, party politicians and education administrators. It concludes that high levels of social inequality and the lack of a universalistic and effective system of welfare provision constitute serious obstacles to the empowerment of disadvantaged groups in developing societies such as Brazil. On the other hand, the article argues that school empowerment has the potential to undermine resilient patronage structures, by introducing universalistic mechanisms of decision‐making and making school administrators more accountable to their constituencies.

Suicidal ideation and self-determination in institutionalized elderly

The right to self-determination is central to the current debate on rational suicide in old age. The goal of this exploratory study was to assess the presence of self-determination in suicidal institutionalized elderly persons. Eleven elderly persons with serious suicidal ideations were matched according to age, sex, and civil status with 11 nonsuicidal persons. The results indicated that suicidal persons did not differ from nonsuicidal persons in level of self-determination. There was, however, a significant difference between groups on the social subscale. Suicidal elderly persons did not seem to take others into account when making a decision or taking action. The results are discussed from a suicide-prevention perspective.     

Nondecision making and inertia in Portuguese health policy

Despite there having been a positive context for initiating health care reforms in Portugal in the past fifteen years (accompanied by political consensus on the nature of the structural problems within the health care system), there has been a lack of reform initiatives. We use a process-based framework to show how institutional arrangements have influenced Portuguese health care reform. Evidence is presented to demonstrate inertia and nondecision making in three critical areas of Portuguese health policy: clarifying the public-private mix in coverage and provision, creating financial incentives and motivation for human resources, and introducing changes in the pharmaceutical market. Several factors seem to explain these processes, namely, problems in the balance of power within the political system, which have contributed to a lack of proper policy discussion; a lack of pluralism in the formation of health care policies (with low participation from citizens and high mobilization among structural interest groups); and the low priority of health care in public sector reforms. Portuguese politicians should be aware of the pitfalls of the current political system that constrain participatory arrangements and pluralism in policy making. In order to pursue health care reform, future governments will need to counterbalance the strong influence of structural interest groups.
