Hot corridors, deterrence, and guardianship: An assessment of the Omaha metro safety initiative

The purpose of this research is to describe the Omaha Metro Safety Initiative (OMSI) and assess its deterrent effects. The OMSI, a multi-agency task force, has been carrying out “hot spot” policing practices focused on traffic corridors in high crime areas. The purpose of OMSI operations is to deter crime through a highly visible “guardianship” presence that emphasizes contacts with citizens. Findings showed that a corridor approach was consistent with a “hot spot” policing strategy, in that operations occurred in hi-density crime areas. Nine crime categories were examined to assess the efficacy of 41 operations carried out in 2008. Generally, OMSI revealed a short term deterrent on crime, with the actual deterrent effect associated with the kind of crime assessed. Business crimes tended to show the most consistent operational deterrent effects. Effects also were more consistent in precincts with greater crime density. The paper concludes with recommendations concerning data gathering and operational effectiveness across a multi-agency task force.     

Reputation management by Chinese universities: Primary profile and comparative features

In this study, we analyse data from 176 Chinese universities to examine the use of reputation symbols on official websites. We find that Chinese universities prefer professional and performative symbols more than moral symbols. Reputation symbols are mainly observed in teaching, research, history and strategy categories, whereas their use in internal operations and the external environment is limited. A comparison with samples from the United States and Nordic countries indicates that their universities differ in the use of reputation symbols, with relatively high emphasis on professional and moral symbols, respectively. This difference can be attributed to divergent national cultures, higher education regimes and globalization. Here, we discuss the implications of our findings on reputation management by universities in a globalized world.     

Implementation of Antibullying Legislation in Iowa Schools: A Qualitative Examination of School Administrators’ Perceived Barriers and Facilitators

Adolescent bullying is linked to numerous adverse psychosocial effects that can persist into adulthood. In response to this problem, in 2007 Iowa adopted an antibullying statute requiring all school districts to adopt an antibullying policy. From 2013–2014, 47 semistructured interviews were conducted with school and district administrators in Iowa. Administrators identified many policy implementation challenges including limited funding and staff, and difficulties selecting prevention programs, applying the law’s bullying definition in investigations, and understanding the school’s jurisdiction for policy enforcement. Contextual barriers to implementation (e.g., media portrayals of bullying and parental attitudes) also emerged. This is the first study to use the interactive systems framework to examine antibullying law implementation, highlighting the importance of coordination among research translators, supportive organizations, and on-the-ground implementers.     

The Relationship of Acculturation and Social Integration to Assaults on Intimate Partners Among Mexican American and Non-Mexican White Students

This study examined the role that Mexican ethnicity, acculturation into Anglo American society, and social integration play in intimate partner violence among a sample of 348 college students. The results indicated that Mexican American ethnicity and acculturation into Anglo American society by Mexican American college students had no relation to intimate partner violence. However, integration into society was associated with a decreased probability of severely assaulting a partner among both Mexican Americans and Non-Mexican Whites. The results support a control theory perspective (social integration) on intimate partner violence.     

Race and the apprehension of inmate misconduct

Race differences in the apprehension of inmate misconduct were examined within a medium security Federal Correctional Institution. Significant race differences were found such that disproportionately more conduct reports (shots) were written on black than white inmates. Explanations of these differences are given. Considering three sets of findings, it was concluded that the probability of racial bias affecting criminal justice decision making will vary according to the status of that decision point on two dimensions: (1) the amount of discretion afforded the decision maker, and (2) the extent to which the decision maker is held accountable for this decision. Therefore, racial bias would be expected to exert its greatest impact upon decision points which allow considerable discretion and which prossess minimal accountability.     

Heart rate changes in response to mild mechanical irritation of the high cervical spinal cord region in infants

Alterations in the heart rate were monitored before, during and after the application of a unilateral mechanical impulse to the high cervical spinal cord region which was administered strictly in connection with the so called manual therapy (diagnosis= KISS). The investigation is based on a survey of 695 infants between the ages of 1 and 12 months. A notable change in the heart rate was evident in 47.2% of all examined infants (n= 695). In 40.1% of these infants, the change in heart rate was characterized by heart rate decrease of 15-83% compared to control conditions. Infants in their first 3 months of life responded more often with a severe bradycardia (50-83% decrease), older infants (7-12 months) more often with a mild bradycardia (15-49.9% decrease). This comparison revealed a significantly increased occurrence of severe bradycardia in the younger age group compared to the group of children >3 months (significance 0.0017). In 12.1% (n= 84) of the infants, the bradycardia was accompanied by an apnea. We discuss the hypothesis that mechanical irritation of the high-cervical region serves as a trigger that may be involved in sudden infant death (SID).     

Quantitative analysis of multiple illicit drugs in preserved oral fluid by solid-phase extraction and liquid chromatography-tandem mass spectrometry

We present a validated method for the simultaneous analysis of basic drugs which comprises a sample clean-up step, using mixed-mode solid-phase extraction (SPE), followed by LC-MS/MS analysis. Deuterated analogues for all of the analytes of interest were used for quantitation. The applied HPLC gradient ensured the elution of all the drugs examined within 14 min and produced chromatographic peaks of acceptable symmetry. Selectivity of the method was achieved by a combination of retention time, and two precursor-product ion transitions for the non-deuterated analogues. Oral fluid was collected with the Intercept, a FDA approved sampling device that is used on a large scale in the US for workplace drug testing. However, this collection system contains some ingredients (stabilizers and preservatives) that can cause substantial interferences, e.g. ion suppression or enhancement during LC-MS/MS analysis, in the absence of suitable sample pre-treatment. The use of the SPE was demonstrated to be highly effective and led to significant decreases in the interferences. Extraction was found to be both reproducible and efficient with recoveries >76% for all of the analytes. Furthermore, the processed samples were demonstrated to be stable for 48 h, except for cocaine and benzoylecgonine, where a slight negative trend was observed, but did not compromise the quantitation. In all cases the method was linear over the range investigated (2-200 microg/L) with an excellent intra-assay and inter-assay precision (coefficients of variation <10% in most cases) for QC samples spiked at a concentration of 4, 12 and 100 microg/L. Limits of quantitation were estimated to be at 2 microg/L with limits of detection ranging from 0.2 to 0.5 microg/L, which meets the requirements of SAMHSA for oral fluid testing in the workplace. The method was subsequently applied to the analysis of Intercept samples collected at the roadside by the police, and to determine MDMA and MDA levels in oral fluid samples from a controlled study.
