This article describes the results of a feedback system designed to improve performance for a Swedish traffic police unit and examined whether such a feedback system was beneficial or detrimental to the attitudes of the officers. As in many Western countries, government organizations are being required to demonstrate their effectiveness with quantitative performance measures. An approach called the Productivity Measurement and Enhancement System (ProMES) was used with three groups of Swedish Traffic Police to do this. ProMES is a method for identifying unit's objectives, developing measures for these objectives, and using this information as feedback. ProMES was developed with these police units and feedback from the system was used over a four-year period. Results indicate that there were substantial increases in performance. There were also decreases in accidents, injuries, and fatalities compared both to baseline and to comparison groups in Sweden. These improvements were made with fewer and fewer police officers each year.  相似文献

This research explores the basis of officer decision making during encounters with juvenile suspects, and compares these encounters to those between police and adults. Specifically, two types of officer behavior are examined: the decision to arrest, and the exercise of authority. Officer behavior during encounters with juvenile suspects is compared and contrasted to encounters with adult suspects. Results from multivariate analyses find juveniles are significantly more likely to be arrested than adults; however, officers do not exercise different levels of authority during interactions with juvenile suspects. Results also indicate that the factors shaping officer behavior varies across age of suspect, namely, the community context and officer's race offer significantly different influences on juveniles than on adults. Other factors also influence officer discretion differently depending on the age of the suspect, most noteworthy being disrespectful demeanor. The results indicate that police officer behavior during encounters with juvenile suspects is very different than during encounters with adults.  相似文献

There are no previous surveys of psychopathy and psychopathic traits in representative general population samples using standardized instruments. This study aimed to measure prevalence and correlates of psychopathic traits, based on a two-phase survey using the Psychopathy Checklist: Screening Version (PCL: SV) in 638 individuals, 16–74 years, in households in England, Wales and Scotland. The weighted prevalence of psychopathy was 0.6% (95% CI: 0.2–1.6) at a cut score of 13, similar to the noncriminal/nonpsychiatric sample described in the manual of the PCL: SV. Psychopathy scores correlated with: younger age, male gender; suicide attempts, violent behavior, imprisonment and homelessness; drug dependence; histrionic, borderline and adult antisocial personality disorders; panic and obsessive–compulsive disorders. This survey demonstrated that, as measured by the PCL: SV, psychopathy is rare, affecting less than 1% of the household population, although it is prevalent among prisoners, homeless persons, and psychiatric admissions. There is a half-normal distribution of psychopathic traits in the general population, with the majority having no traits, a significant proportion with non-zero values, and a severe subgroup of persons with multiple associated social and behavioral problems. This distribution has implications for research into the etiology of psychopathy and its implications for society.  相似文献

Research Summary Police scholars and public policymakers throughout generations have sought to identify reliable correlates of police misconduct. Despite these efforts, general statements as to the etiology and epidemiology of police misconduct remain inconclusive, in part because of the inconsistent definitions of misconduct and the difficulty of obtaining the data required to make such statements. This research attempts to fill these gaps through a comparison of the personal and career histories of all 1,543 officers who were involuntarily separated from the New York City Police Department (NYPD) for cause during 1975–1996 with a randomly selected sample of their police academy classmates who served honorably. The study uses confidential NYPD files as its major data sources, which include extensive biographical and career information. The study finds that career‐ending misconduct rarely occurs in the NYPD and that the types of misconduct do not match well with existing definitions. Several factors emerge as significant predictors of misconduct, including officer race, minimal education, records of prior criminality and prior poor employment, failure to advance in the NYPD, and histories of citizen complaints. Policy Implications This study shows that existing definitions of police misconduct are difficult to apply to actual cases of police malpractice, which leads the authors to create a new eight‐category classification scheme. The rarity of misconduct, especially on‐duty abuse, confirms prior research indicating that most police officers do their jobs without engaging in serious malpractice. These findings suggest that the NYPD has become better behaved as it has become more diverse along race and gender dimensions and that the link between black officers and misconduct might be explained by persistent “tokenism.” The findings related to race have important implications for continued efforts to build racially representative police departments. Personal history findings highlight the importance of conducting background investigations that disqualify candidates with arrest records and employment disciplinary histories, whereas the inverse relationship between college education and misconduct provides strong support for continued emphasis on pre‐ and post‐employment educational requirements.  相似文献

Is globalization promoting regulatory convergence in agricultural biotechnology policies in the South? This article examines the nature and limits of regulatory convergence in the field of agri-biotechnology and investigates the effects that international forces have on biotechnology and biosafety policies in developing countries. Based on detailed case studies of Mexico, China and South Africa this article shows that these three leading biotechnology countries in the South are exposed to powerful international influences but are responding to the regulatory challenges of genetically modified organisms (GMO) adoption in distinctive ways. The existing regulatory polarization between US and EU biotechnology approaches has not forced a convergence around either of these two international models. GMO policies in the South do not simply follow the binary logic of the US–EU regulatory conflict. Instead, they integrate elements from both regulatory approaches and are steering a course that suggests substantial regulatory diversity in the South. The globalization of biotechnology thus goes hand in hand with regulatory diversity in the developing world. Furthermore, regulatory polarization between the EU and US has helped to open up political space in key developing countries.  相似文献

This article considers methodological issues arising from recent efforts to provide field tests of eyewitness identification procedures. We focus in particular on a field study (Mecklenburg 2006) that examined the “double blind, sequential” technique, and consider the implications of an acknowledged methodological confound in the study. We explain why the confound has severe consequences for assessing the real-world implications of this study.  相似文献
