Sexual offenses represent an alarming proportion of crimes committed yearly. To address these concerns, several states, including South Carolina (SC), have enacted laws requiring sexually violent predators (SVPs) to be civilly committed to treatment. To date, no published study has examined sexual offenders recommended for treatment in SC. This study used a specially designed statewide database (SC-SVP research database) to determine which offender and offense characteristics were associated with increased likelihood of being recommended for civil commitment. Factors correlated with being more likely to be recommended included: being of a younger age at time of evaluation, prior sex convictions, having related and unrelated victims, a higher number of victims, frequent substance use, and a history of suicide attempts. Prior sex convictions, having both related and non-related victims, and a higher total number of victims align with characteristics associated with sexual recidivism. Frequent substance abuse and a history of suicide attempts do not mirror previous findings regarding sexual recidivism. These findings present new information regarding the civil commitment process of offenders being committed to the SC-SVP treatment program, characterize types of offenders committed to SC-SVP treatment program, and provide a foundation for using a computerized database in conducting sex offender research.  相似文献

This study analyses the extent, sense, and strategies employed by sympathisers with Spanish state-wide left-wing parties to ‘reconstruct’ their affective ties with the Spanish nation after the ‘monopolisation of patriotism’ by Franco's regime. Such an undertaking is further complicated within the context of economic crisis and intensified peripheral nationalism found in Catalonia and the Basque Country. This article applies qualitative analysis to the discourse of left-wing participants from 11 focus groups held in March 2012 amidst the economic (and political) crisis. As expected, this context of crisis favoured the emergence of explicit discourse on the Spanish nation, providing an opportunity to gain a better understanding of its nature. Findings show that welfare nationalism and social patriotism define the kind of attachment developed by the interviewees towards Spain better than the concept of constitutional patriotism, or any kind of ethnic-cultural feeling of belonging.  相似文献

This paper reflects on the use of a participatory learning and action (PLA) framework in a strategic planning process (SPP) at a primary school in rural Kenya. Successes and challenges are discussed, focusing on the barriers to fully implementing the PLA framework. Additionally, lessons learnt and ways forward for participatory SPPs are outlined. The PLA framework allowed the project stakeholders to engage in a planning process that gave participants a voice in the process. Although PLA methodology faces shortcomings, the application of this model is a step towards making community development more sustainable.  相似文献

The fact that university degrees are accepted throughout Europe has led to the founding of medical faculties, especially in Central and Eastern Europe, that offer medical studies in German or English and thus attracting students from richer Western European countries like Germany. Unlike medical studies in Germany, access to these foreign universities is not dependent on the final school exam grade, but on the ability to pay high tuition fees. The article compares the social class background of medicine students in Germany with German medicine students in Hungary. The analysis shows that the percentage of medicine students who come from higher social classes is even higher in Hungary than it already is in Germany. Studying medicine in Hungary primarily serves as an immediate reproduction of the parents’ profession as many of German medicine students in Hungary have a parent who belongs to the medical profession. The case of German students studying medicine abroad illustrates how Europeanization and Globalization have changed the reproduction of social inequalities; upper classes profit most from the new opportunities.  相似文献

As is clear from the historiography of the US decision to use the atomic bomb on Hiroshima, the judgments of historians are relative to the time, place, and perspective from which they are writing. There are four major schools of historical interpretation of the decision. First is the orthodox view that was offered by the participants in the decision. Second is the revisionist view of historians writing during the era of the Vietnam war who adopted a much more critical interpretation. Third is an interpretive school that gives weight to the Japanese role and responsibility. Finally, the author's view is found in a more long-range perspective that finds the momentum created by President Roosevelt's unconditional surrender policy as the decisive factor. This policy provoked unconditional resistance in the Japanese military. By 1945 the legacy of Roosevelt's policy was firmly embedded in American public opinion. Historians have reached no consensus among these different interpretive schools.  相似文献

Opioid‐related mortality happens, even in healthcare settings. We describe serial postmortem fentanyl blood concentrations in a hospital inpatient who fatally abused transdermal fentanyl. This is a single‐patient case report. A 42‐year‐old man with lymphoma was started on transdermal fentanyl therapy while hospitalized for chronic abdominal pain. The patient was last seen awake 1.3 h prior to being found apneic and cyanotic. During the resuscitation attempt, a small square‐shaped film was removed from the patient's oropharynx. Femoral blood was collected 0.5 and 2 h postmortem, and the measured fentanyl concentration increased from 1.6 to 14 ng/mL. Study limitations include potential laboratory or collection errors and missing data. (i) Providers must be vigilant for signs of fentanyl patch abuse. (ii) Postmortem blood concentrations are not static postmortem, likely secondary to decreasing pH, increased aqueous solubility, and tissue redistribution, and are therefore unlikely to accurately represent antemortem blood concentrations.  相似文献

Judges and juries tend to be particularly impressed by test data, especially quantitative test data. Psychometric tests specific for assessing the presence of post‐traumatic stress disorder (PTSD) are commonly employed by forensic mental health evaluators. Most of these instruments, however, have been designed to detect PTSD in treatment or research, and not forensic, settings. Those who rely on these measures without adequate awareness of their often significant limits in correctly identifying malingering may induce finders of fact to inordinately confidently accept the presence of PTSD. This article reviews problematic structural and content components of trauma‐specific and related instruments used to evaluate PTSD and discusses the utility of specific techniques liable to be used in forensic settings to “fool” these measures.  相似文献

Color separation is an image processing technique that has often been used in forensic applications to differentiate among variant colors and to remove unwanted image interference. This process can reveal important information such as covered text or fingerprints in forensic investigation procedures. However, several limitations prevent users from selecting the appropriate parameters pertaining to the desired and undesired colors. This study proposes the hybridization of an interactive differential evolution (IDE) and a color separation technique that no longer requires users to guess required control parameters. The IDE algorithm optimizes these parameters in an interactive manner by utilizing human visual judgment to uncover desired objects. A comprehensive experimental verification has been conducted on various sample test images, including heavily obscured texts, texts with subtle color variations, and fingerprint smudges. The advantage of IDE is apparent as it effectively optimizes the color separation parameters at a level indiscernible to the naked eyes.  相似文献
