Political parties are critical to Latin American democracy. This was demonstrated in Peru, where an atomized, candidate-centered party system developed after Alberto Fujimori's 1992 presidential self-coup. Party system decomposition weakened the democratic opposition against an increasingly authoritarian regime. Since the regime collapsed in 2000, prospects for party rebuilding have been mixed. Structural changes, such as the growth of the informal sector and the spread of mass media technologies, have weakened politicians' incentive to build parties. Although these changes did not cause the collapse of the party system, they may inhibit its reconstruction.  相似文献

This longitudinal project examined peer influence across five risk behaviors: cigarette smoking, alcohol consumption, marijuana use, tobacco chewing, and sexual debut. A total of 1,969 adolescents aged 12–18 years completed two waves of data collection. Each respondent matched behavior data for at least one friend. Results found that a random same sex peer predicts a teen's risk behavior initiation; there is influence only to initiate cigarette and marijuana use; and that there is influence to initiate and stop alcohol and chewing tobacco use. This finding suggests that friends may protect adolescents from risk activities. The study has implications for understanding how peer influence, expressed as social norms, may be used in public health campaigns that target teen behavior.  相似文献

This study assessed the extent to which participatory methods had been used by CIMMYT, and how the scientists perceived them. Results suggest that participatory approaches at the Center were largely ‘functional’ – that is, aimed at improving the efficiency and relevance of research – and had in fact added value to the research efforts. The majority of projects surveyed also placed emphasis on building farmers' awareness. This is understandable if we think that the limiting factor in scientist–farmer exchange is the farmers' limited knowledge base. Thus, in situations such as marginal areas and in smallholder farming, exposure to new genotypes and best-bet management options would be a first requirement for effective interactions and implementation of participatory approaches.  相似文献

Abstract:  Information on homicide offenders guilty of mutilation is sparse. The current study estimates the rate of mutilation of the victim's body in Finnish homicides and compares sociodemographic characteristics, crime history, life course development, psychopathy, and psychopathology of these and other homicide offenders. Crime reports and forensic examination reports of all offenders subjected to forensic examination and convicted for a homicide in 1995–2004 ( n  = 676) were retrospectively analyzed for offense and offender variables and scored with the Psychopathy Check List Revised. Thirteen homicides (2.2%) involved mutilation. Educational and mental health problems in childhood, inpatient mental health contacts, self-destructiveness, and schizophrenia were significantly more frequent in offenders guilty of mutilation. Mutilation bore no significant association with psychopathy or substance abuse. The higher than usual prevalence of developmental difficulties and mental disorder of this subsample of offenders needs to be recognized.  相似文献

Abstract: With populations aging there have been some concerns on elderly offending. We compared elderly homicide offenders with a younger comparison group with special emphasis on psychopathy. We analyzed nationwide register‐based material on all homicide offenders aged 60 or older who were in a forensic psychiatric examination in Finland 1995–2004 and their gender‐matched comparison group of younger homicide offenders. The offenders 60 years or older were diagnosed less often than the younger ones with drug dependence and personality disorders and more often with dementia and physical illnesses. The mean Psychopathy Checklist—Revised total scores as well as factor and facet scores were lower in the 60 or older age group. The group 60 years or older had significantly lower scores on eight individual items of social deviance. The interpersonal/affective factor 1 scores did not differ. Understanding the possible underlying phenomena of violent behavior may provide help for developing services for the elderly.  相似文献

Criminal legally responsible for responsibility in Israel his crimes unless the is defined in terms of polarity: all or nothing. An individual is court has determined that he is exculpated from criminal responsibility; there is no diminished criminal responsibility. The authors present a unique case where two expert psychiatrists determined that the accused was culpable for the first crime, rape, but was exculpated from criminal responsibility for the second crime, stabbing, which was committed immediately thereafter. As per the court approved plea bargain, the accused was charged only with rape, and was sentenced to incarceration in the psychiatric ward of the prison. The social significance of the expert psychiatric opinion and the court ruling will be examined in this paper.  相似文献
