We report on a project to explore empirical patterns in risk, shocks and risk management using recent household surveys with risk modules from 16 different developing countries. Natural disasters, health shocks, economic shocks, and asset loss are the most commonly reported types of shocks and, especially for the poor, often result in ‘bad’ coping responses that may perpetuate vulnerability. The information culled from these survey modules falls short of expectations in several ways. 相似文献

The objective of this study was to investigate psychological or physical violence associated with the use of alcohol, in residences
of individuals in Brazil and, also describe the social characteristics of aggressors and victims. Therefore, this study expects
to contribute to studies in Brazil that seek to clarify the relations between alcohol and violence in residences. A total
of 454 respondents, 12–65 years old, were assessed, they were sorted by the Kish method, and the residences randomly. The
SAMHSA questionnaire was utilized after translated and adapted to Brazilian conditions. 26% of the individuals reported psychological
violence, and 16% reported physical violence. The study’s main results set the differences in the reports for physical violence
(OR 7, 95% CI: 4–13) and psychological violence (OR 5, 95% CI: 3–8) in residences where someone arrived or became intoxicated
with alcohol (P < 0.05). 50% of the aggressors were under the effects of alcohol, and 77% of the victims were relatives of their aggressors.
Acts of violence are not necessarily associated with alcohol consumption. Men and women reported acts of domestic violence;
psychological violence was the most prevalent form. Men are currently the primary aggressors, while women are primarily the
victims 相似文献

Abstract: In fire debris analysis, weathering of ignitable liquids and matrix interferences can make the identification of ignitable liquid residues (ILRs) difficult. An objective method was developed to associate ILRs with the corresponding neat liquid with discrimination from matrix interferences using principal components analysis (PCA) and Pearson product moment correlation (PPMC) coefficients. Six ignitable liquids (gasoline, diesel, ultra pure paraffin lamp oil, adhesive remover, torch fuel, paint thinner) were spiked onto carpet, which was burned, then extracted using passive headspace extraction, and analyzed by gas chromatography‐mass spectrometry. Both light and heavy burn conditions were investigated. In the PCA scores plot, ignitable liquids were discriminated based on alkane and aromatic content. All ILRs were successfully associated with the corresponding neat liquid using both PCA and PPMC coefficients, regardless of the extent of burning. The method developed in this research may make the association of ILRs with corresponding neat liquids more objective. 相似文献

There is widespread acceptance that current institutions are inadequate to address the challenges of sustainable development. At the same time, there is an urgent need to build awareness and increase capacity for promoting action with respect to environmental protection at the local level. This article analyzes the Web sites of the environment departments of European local governments that signed the Aalborg Commitments to determine the extent to which they are using the Internet to promote e‐participation in environmental topics and to identify the drivers of these developments. Potential drivers are public administration style, urban vulnerability, external pressures, and local government environmental culture. Findings confirm that e‐participation is a multifaceted concept. External pressures influence the transparency of environmental Web sites, while public administration style and local government environmental culture influence their interactivity. 相似文献

There is considerable evidence that neurocognitive deficits are frequent among incarcerated offenders. However, current correctional programming does not directly seek to remediate deficits in offenders’ neurocognitive deficits. In this pilot project, we sought to treat neurocognitive deficits in incarcerated Portuguese adult women offenders (n?=?28) using cognitive remediation to target cognitive flexibility, memory, and planning. Statistically significant positive changes, with medium to large effect sizes, were discovered across several neurocognitive domains, including attention, speed of processing, verbal learning and memory, cognitive flexibility, and planning. We also found a decrease in the negative emotional states of depression, anxiety, tension/stress, and on disturbed behavior in prison. Cognitive remediation has the potential to enhance the neurocognitive functioning of incarcerated women. Controlled research is needed to establish cognitive remediation fully as an intervention for the treatment of neurocognitive deficits of incarcerated women. 相似文献

Confidence and other testimony-relevant judgments may be distorted when witnesses are given confirming postidentification feedback, and double-blind procedures-wherein the lineup administrator does not know the identity of the suspect-are a commonly proposed, but untested, remedy for this effect. In the current study, mock witnesses viewed a staged crime video followed by a target-present or target-absent lineup where the administrator was or was not presumed to know the identity of the suspect. After making an identification decision, witnesses were or were not given realistic, but nonidentification-specific, feedback, and then confidence and other judgments were assessed. A significant interaction was found between blind condition and feedback such that feedback inflated confidence and other judgments in presumed nonblind conditions only; feedback had no effect on participants in presumed blind conditions. As predicted by the selective cue integration framework-a theoretical model suggested to explain the interaction between presumed blind administration and feedback-this interaction was significant only for inaccurate participants. These results suggest that blind administration may serve as a prophylactic against the negative effects of postidentification feedback. In addition, the effectiveness of our subtle feedback in influencing judgments suggests that lineup administrators should take care not to provide any feedback to eyewitnesses.

Forensic age estimation is an important element of anthropological research, as it produces one of the primary sources of data that researchers use to establish the identity of a person living or the identity of unknown bodily remains. The aim of this study was to determine if the chronology of third molar mineralization could be an accurate indicator of estimated age in a sample Brazilian population. If so, mineralization could determine the probability of an individual being 18 years or older. The study evaluated 407 panoramic radiographs of males and females from the past 5 years in order to assess the mineralization status of the mandibular third molars. The evaluation was carried out using an adaptation of Demirjian's system. The results indicated a strong correlation between chronological age and the mineralization of the mandibular third molars. The results indicated that modern Brazilian generation tends to demonstrate an earlier mandibular third molar mineralization than older Brazilian generation and people of other nationalities. Males reached developmental stages slightly earlier than females, but statistically significant differences between the sex were not found. The probability that an individual with third molar mineralization stage H had reached an age of 18 years or older was 96.8-98.6% for males and females, respectively. 相似文献

Parental responsibility laws, varying greatly within and among the states, appeared as one answer to the questions surrounding juvenile crime. Although these laws would seem to garner great public support under the new punitive attitude toward juveniles, no recent empirical studies were conducted on this topic. The current research examined public support of parental responsibility for crimes children commit. Contrary to expectations, public support was found to be relatively low. The public did place some responsibility on the parents when a juvenile crime occurred; however, agreement with blaming and punishing the parents was low. Political ideology and educational status served as possible predictors of support. Overall, however, demographic variables proved not predictive in determining who would support these measures. 相似文献
