This study sought to analyse the relation between executive functions and criminal recidivism. We assessed a set of cognitive abilities associated with executive functioning in a group of recidivist offenders (n = 19), primary offenders (n = 25) and non-offenders (n = 30). Our results, tested with nonparametric statistics and Monte Carlo method, revealed that there were no executive differences between both groups of offenders but, when compared with non-offenders, the recidivists showed a worse performance in Trail Making Test part B, and the primary offenders presented a significant lower score on Porteus Maze Test Age score. This study suggests that there can be a different pattern of executive functioning deficits associated with the offenders’ criminal record: recidivism may be more related to mental flexibility impairments and primary offenders’ antisocial behaviour may be aggravated by planning deficits. 相似文献

This study investigated the influence of paraquat, a prevalent poison used by suicides, on initial oviposition and development of Chrysomya megacephala (Fabricius) using minced‐beef substrates. Paraquat in lethal dose for human (40 mg/kg), two times the lethal dose (80 mg/kg) and five times the lethal dose (200 mg/kg) were mixed thoroughly with respective minced‐beef substrates (1 kg each) that were decomposed in a shaded habitat fully protected from rain. Results of four replications of the above experiment revealed that the presence of paraquat neither delayed initial oviposition nor prolonged the developmental stages of C. megacephala. Therefore, estimation of postmortem interval (PMI) based on empirical baseline data obtained using animal models devoid of any poisons would still be appropriate for estimating PMI in paraquat‐related deaths. 相似文献

This article examines why the BRICS Development Bank is being created and the role it will play in the global economy and world development. After describing some of the critical needs that are driving the formation of this new multilateral development bank, I discuss how the creation of the BRICS bank is linked to failures among traditional funders to deliver on their commitments, especially in terms of infrastructure investment. This article also outlines the national interests that each BRICS country has in the BRICS bank, and the main challenges that the BRICS countries are facing in transforming this idea into reality. 相似文献

The case of a 22‐year‐old male Caucasian driver is presented. He was involved in a traffic collision. At the roadside, he displayed blank stare and mellow speech with a barely audible voice. A DRE found low body temperature, rigid muscle tone, normal pulse, lack of horizontal and vertical gaze nystagmus, nonconvergence of the eyes, dilated pupil size, and normal Pupillary reaction to light. A standard toxicology DUID protocol was performed on the driver's whole blood including ELISA and GC‐MS drug screens with negative results. Additional drug screening was undertaken for bath salts and synthetic cannabinoid receptor agonists by LC‐MS/MS by a commercial laboratory and identified the synthetic cannabinoid receptor agonist XLR‐11 in the driver's blood. XLR‐11 was subsequently quantified at 1.34 ng/mL. This is the first documented case involving a driver operating a motor vehicle under the influence of the synthetic cannabinoid receptor agonist XLR‐11. 相似文献

Prolapse rectum (PR) or protrusion of the rectum beyond the anus occurs frequently in populations at both extremes of age. In the pediatric population, in developed countries, the commonest cause for PR is thought to be cystic fibrosis (CF). Treatment options for CF include conservative management, surgical resection and fixation, suturing, and injection sclerotherapy (IS). The last is considered an attractive treatment option because it is minimally invasive. In this case report, the authors present the details about a 2-year-old female child, with PR and CF, who died after IS, using phenol as the sclerotherapeutic agent. Autopsy findings and toxicology tests performed to establish phenol toxicity are documented. The available literature is reviewed. This case report underscores the risks of using phenol for IS and emphasizes the point that the procedure is not innocuous and an adverse outcome including fatality is a possibility. 相似文献

This study revisited the Philadelphia Foot Patrol Experiment and explored the longitudinal deterrent effects of foot patrol in violent crime hot spots using Sherman's (1990) concepts of initial and residual deterrence decay as a theoretical framework. It also explored whether the displacement uncovered during the initial evaluation decayed after the experiment ended. Multilevel growth curve models revealed that beats staffed for 22 weeks had a decaying deterrent effect during the course of the experiment, whereas those staffed for 12 weeks did not. None of the beats had residual deterrence effects relative to the control areas. The displacement uncovered had decayed during the 3 months after the experiment, and it is theoretically plausible that previously displaced offenders returned to the original target areas causing inverse displacement. These results are discussed in the context of Durlauf and Nagin's (2011) recent proposal that prison sentences should be shortened, mandatory minimum statutes repealed, and the cost savings generated by these policy changes shifted into policing budgets to convey more effectively the certainty of detection. It is concluded that if Durlauf and Nagin's proposal is to succeed, then more holistic policing strategies would likely be necessary. Foot patrol as a specific policing tactic seems to fit nicely into a variety of policing paradigms, and suggestions for incorporating them to move beyond strictly enforcement‐based responses are presented. 相似文献

Pressure in the 1970's to reform the sentencing process can be attributed to a change in perceived public sentiment regarding the utility of treatment and to the belief that sentencing disparity was a severe problem in the sentencing process. Primary reform occurred in the federal judicial system with the development and implementation of rigorous sentencing guidelines. An evaluation of sentencing patterns for one federal judicial district indicates that sentencing disparity was not severe. Most federal offenders are relatively mild and consistently receive relatively mild sentences. 相似文献

Abstract This paper reviews assessment, treatment and supervision issues in relation to a high-risk, borderline functioning, male sex offender with zoosexual interests and behaviours. Mr Z was convicted of multiple sexual offences including rape, indecent assault and indecent exposure as well as actual and threatened bodily harm. He was convicted for two counts of attempted buggery of horses and he received a Probation Order to engage in group and individual work, as deemed appropriate. Significant treatment challenges emerged due to his cognitive/intellectual difficulties, coping problems (including anger management issues) and dissimulation. Further, continuing evidence of high-risk behaviours associated with his index offence as well as previously identified patterns of offending were reported. Ongoing concerns prompted a referral for a polygraph examination to gain additional information about Mr Z's offence history and to achieve a better understanding of his treatment needs. These findings are discussed and specific attention is focused on Mr Z's zoosexual behaviours. 相似文献
