Opiate analysis in cadaveric blowfly larvae as an indicator of narcotic intoxication

Specimens of liver were collected from 40 cases in which the cause of death had been determined to be opiate intoxication. Rearings of Calliphora vicina larvae were then promoted on the decomposing liver. A control group of 10 decomposed liver specimens from non-opiate deaths was treated similarly. Analysis of larvae and liver for opiates (morphine) was conducted by radioimmunoassay. Good qualitative and quantitative correlation was observed in both the positive and negative groups. Regression analysis comparing the concentrations of opiates found in the larvae with those found in the liver in the positive group resulted in a correlation of r = 0.790.     

How do voters form positive economic beliefs? Evidence from the Survey of Americans and Economists on the Economy

Beliefs about normative economics appear to be primarily determined by sociotropic rather than egocentric variables. (Sears & Funk, 1990; Citrin & Green, 1990) Using the Survey of Americans and Economists on the Economy, the current paper finds that the same holds for positiveeconomic beliefs in most – but not all – cases. This hinges on whether a question is “causal” or “non-causal”: Causal beliefs depend on sociotropic variables, especially education and ideology; non-causal beliefs, in contrast, depend on egocentric variables, with income growth playing the leading role. This is consistent with a cognitive model where actors answer easier questions using personal experience, and harder ones with ``off-the-shelf" theories.     

Forensic handwriting examiners' expertise for signature comparison

This paper reports on the performance of forensic document examiners (FDEs) in a signature comparison task that was designed to address the issue of expertise. The opinions of FDEs regarding 150 genuine and simulated questioned signatures were compared with a control group of non-examiners' opinions. On the question of expertise, results showed that FDEs were statistically better than the control group at accurately determining the genuineness or non-genuineness of questioned signatures. The FDE group made errors (by calling a genuine signature simulated or by calling a simulated signature genuine) in 3.4% of their opinions while 19.3% of the control group's opinions were erroneous. The FDE group gave significantly more inconclusive opinions than the control group. Analysis of FDEs' responses showed that more correct opinions were expressed regarding simulated signatures and more inconclusive opinions were made on genuine signatures. Further, when the complexity of a signature was taken into account, FDEs made more correct opinions on high complexity signatures than on signatures of lower complexity. There was a wide range of skill amongst FDEs and no significant relationship was found between the number of years FDEs had been practicing and their correct, inconclusive and error rates.     

Acute deaths in nonpregnant adults due to invasive streptococcal infections

Streptococcal organisms, part of the normal human bacterial flora, occasionally become infectious pathogens responsible for a wide array of clinical syndromes, ranging from mild pharyngitis to death. Notably, infections due to group A and group B beta-hemolytic strains are well known for causing invasive disease leading to death. These deaths, while often suspected clinically, occasionally are not diagnosed until autopsy. We present 3 rapid deaths, with very different presentations, due to streptococcal infection. Two decedents experienced sudden deaths due to pneumonia and severe meningoencephalitis caused by group B beta-hemolytic streptococcal infection, a common cause of neonatal meningitis but only rarely reported in nonpregnant adults. The final case involves a 69-year-old male who presented to the emergency room with a complaint of shoulder pain but over the next several hours developed signs of necrotizing fasciitis, became septic, and died. While antemortem cultures were negative, owing to antibiotic administration, postmortem cultures of bone and deep soft tissue were positive for group A beta-hemolytic Streptococcus sp. Acute and sudden deaths due to infectious etiology represent an uncommon yet well-documented occurrence. The importance of appropriate postmortem cultures in these situations and a review of the literature will be discussed.     

Facilitators and Impediments to Designing,Implementing, and Evaluating Risk-Based Policing Strategies Using Risk Terrain Modeling: Insights from a Multi-City Evaluation in the United States

The contemporary policing literature contains numerous examples of partnerships between academic researchers and police agencies. Such efforts have greatly contributed to evidence-based policing by increasing the knowledge base on effective strategies. However, research has demonstrated that successful collaboration between researchers and practitioners can be a challenge, with various organizational and inter-agency factors presenting difficulties at various stages of the process. Additionally, applied research can oftentimes face implementation challenges when the time comes to convert research into practice. The current study contributes to the literature by discussing researcher/practitioner partnerships and program implementation in the context of a multi-city risk-based policing project in the United States. We conceptualize police interventions as contingent on four distinct phases: 1) problem analysis, 2) project design, 3) project implementation, and 4) project evaluation. In this project, the research partners were able to successfully complete each phase in certain cities while the project experienced difficulty at one or more phases in other cities. We discuss these disparate experiences, identifying factors that facilitate or impede successful completion of each step. Policy implications and recommendations for future risk-based policing interventions are discussed.     

Proposed modification of a school-wide bully prevention program to support all children

Bullying prevention programs in the United States are being implemented in schools from kindergarten through high school to reduce rates of bullying behaviors. The bully prevention in positive behavior support (PBIS) model is an evidence-based, whole school intervention program. The PBIS model trains teachers, school staff, and administrators to model and provide positive reinforcement for children to decrease bullying amongst peers. This article addresses gaps in the current bullying prevention research by exploring challenges and potential modifications to the PBIS model based on staff perspectives of specific student needs. Utilizing focus group methodology, administrators, teachers, and support staff in a northeastern urban elementary school identified challenges experienced by students who were English language learners, impulsive, shy or sensitive, and female. The findings highlight the critical nature of school–parent relationships in addressing student, family, and cultural factors that influence the successful implementation of bullying prevention programs.     

Injuries of the Head from Backface Deformation of Ballistic Protective Helmets Under Ballistic Impact

Modern ballistic helmets defeat penetrating bullets by energy transfer from the projectile to the helmet, producing helmet deformation. This deformation may cause severe injuries without completely perforating the helmet, termed “behind armor blunt trauma” (BABT). As helmets become lighter, the likelihood of larger helmet backface deformation under ballistic impact increases. To characterize the potential for BABT, seven postmortem human head/neck specimens wearing a ballistic protective helmet were exposed to nonperforating impact, using a 9 mm, full metal jacket, 124 grain bullet with velocities of 400–460 m/s. An increasing trend of injury severity was observed, ranging from simple linear fractures to combinations of linear and depressed fractures. Overall, the ability to identify skull fractures resulting from BABT can be used in forensic investigations. Our results demonstrate a high risk of skull fracture due to BABT and necessitate the prevention of BABT as a design factor in future generations of protective gear.     

Gender Differences in Risk Markers for Perpetration of Physical Partner Violence: Results from a Meta-Analytic Review

There is a lack of consensus on whether the use of intimate partner violence (IPV) is distinctly different between men and women, or if men and women share similar risk markers for perpetrating IPV. In this study, we compared 60 different risk markers for IPV perpetration for men and women using a meta-analysis. We found three out of 60 risk markers significantly differed between men and women. Our results suggest that there are more similarities between men and women than there are differences in risk markers for IPV perpetration.     

Unpaid debt to society: exploring how ex-felons view restrictions on voting rights after the completion of their sentence

The Supreme Court has asserted that ex-felon disenfranchisement is not a punishment. Regardless of the Court’s interpretation, however, many ex-felons perceive restrictions on voting rights as punitive. Therefore, felony disenfranchisement should be examined in terms of criminological theories of sanctions. In Florida, ex-felons are prevented from voting after the completion of their sentence until they go through a lengthy and in some cases impossible process of rights restoration. The consequences of this policy have resulted in hundreds of thousands of Floridians who have completed their sentences, but are unable to vote. This research employs 54 semi-structured interviews with men convicted of felonies in Florida who have lost the right to vote, but have completed their sentencing obligations to the state. Our purpose is to better understand the meaning former offenders attribute to the loss of their civil rights. Findings from this study suggest that many former offenders view this type of punishment as illegitimate and are angered by both the complex system of restoration and the inability to participate in democratic life. Other ex-offenders are embarrassed or fatalistic about their loss of rights. The implications for criminal justice policies and practices are discussed.
