Positive versus normative economics: what’s?the?connection? Evidence from the Survey of?Americans and?Economists on the Economy and?the?General?Social?Survey

Previous research suggests that positive and normative beliefs about economics are largely unrelated. Using questions from two national surveys, this study finds that: (a)?the underlying determinants of positive and normative beliefs are strikingly similar; (b)?education is by far the strongest overall determinant of both positive and normative beliefs; and (c) the variables known to push positive beliefs in the same direction as formal economic training—education, male gender, income growth, and job security—also push normative beliefs in the same direction. These results strongly suggest that the positive-normative connection has been underestimated.     

Survey Research in Public Administration: Assessing Mainstream Journals with a Total Survey Error Framework

Survey research is a common tool for assessing public opinions, perceptions, attitudes, and behaviors for analyses in many social science disciplines. Yet there is little knowledge regarding how specific elements of survey research methodology are applied in practice in public administration. This article examines five mainstream public administration journals over an eight‐year period regarding current methodological practice, organized around the total survey error framework. The findings show that survey research in the field of public administration features mainly small‐scale studies, heavy reliance on a single data collection mode, questionable sample selection procedures, and suspect sample frame quality. Survey data largely are analyzed without careful consideration of assumptions or potential sources of error. An informed evaluation of the quality of survey data is made more difficult by the fact that many journal articles do not detail data collection procedures. This study concludes with suggestions for improving the quality and reporting of survey research in the field.     

Physical components of soft-tissue ballistic wounding and their involvement in the generation of blood backspatter*

Gunshot backspatter comprises biological material expelled backward through bullet entry holes. Crime scene investigators analyze backspatter patterns to infer wounding circumstances. An understanding of the mechanism of backspatter generation, and the relationship between spatter patterns and bullet and tissue characteristics, would enhance the predictive value of such analysis. We examined soft-tissue ballistic wounding responses to determine the underlying components and how these might be relevant to the generation of backspatter. We identified five mechanistic components to ballistic wounding (elastic, viscous, crushing, cutting, and thermal), each related to mechanical disciplines (respectively, solid mechanics, fluid mechanics, fracture mechanics, rheology, and thermodynamics). We identified potential roles for these five components in backspatter formation and provide a scenario whereby a sequence of events incorporating these components could lead to backspatter generation and expulsion. This research provides a framework for the mathematical representation, and subsequent computational predictive modeling, of backspatter generation and pattern formation.     

The ghost that slayed the mandate

Virginia v. Sebelius is a federal lawsuit in which Virginia has challenged President Obama's signature legislative initiative of health care reform. Virginia has sought declaratory and injunctive relief to vindicate a state statute declaring that no Virginia resident shall be required to buy health insurance. To defend this state law from the preemptive effect of federal law, Virginia has contended that the federal legislation's individual mandate to buy health insurance is unconstitutional. Virginia's lawsuit has been one of the most closely followed and politically salient federal cases in recent times. Yet the very features of the case that have contributed to its political salience also require its dismissal for lack of statutory subject matter jurisdiction. The Supreme Court has placed limits on statutory subject matter jurisdiction over declaratory judgment actions in which a state seeks a declaration that a state statute is not preempted by federal law--precisely the relief sought in Virginia v. Sebelius. These statutory limits are a sea wall; they keep out, on statutory grounds, some suits that should otherwise be kept out on Article III grounds. The statutory and constitutional limits on federal jurisdiction over suits like Virginia v. Sebelius insulate federal courts from the strong political forces surrounding lawsuits that follow from state statutes designed to create federal jurisdiction over constitutional challenges by states to federal law. This Article identifies previously neglected jurisdictional limits, shows why they demand dismissal of Virginia v. Sebelius, and explains why it is appropriate for federal courts to be closed to suits of this type.     

Predicting Police Aggression: Comparing Traditional and Non-Traditional Prediction Models

Psychologists can help to reduce inappropriate aggressive behavior through careful screening of police officer candidates. The purpose of this study was to identify whether the IAT Reasoning Test (IAT), a measure of trait aggression, and a Monetary Delay Discounting Task (MDDT), a measure of behavioral control, could predict on-the-job police aggression better than the MMPI-2. We administered the MMPI-2, the IAT, and the MDDT to 85 police officers. Three prediction models were created using scores on the IAT and the MDDT, and scales from the MMPI-2. Model 1 included the IAT and the MDDT. Model 2 included MMPI-2 scales Hostility (HO), Overcontrolled Hostility (OH), and Anger (ANG). Model 3 included MMPI-2 scales Frequency (F), Hysteria (HY), and Psychopathic Deviate (PD). We found that Model 1 was the only predictor of supervisors?? ratings of on-the-job aggression, however, the predictive utility of this model was attributable primarily to the MDDT predictor. Based on these findings, we suggest that using measures of behavioral control during preemployment screening may help to identify potentially aggressive police officer candidates.     

Planning Ahead? An Exploratory Study of South Korean Investigators’ Beliefs About Their Planning for Investigative Interviews of Suspects

Preparation and planning has been argued to be vitally important as to how effectively investigators undertake their interviews with suspects. Yet, it has also been found in previous research that investigators admit that they plan only occasionally, often attributing insufficient time as a reason for not undertaking the task. Employing a novel research paradigm that utilised theoretical foundations concerning planning, the present study explored empirically 95 South Korean financial crime investigators’ views, using a self-administered questionnaire. With the use of second-generation statistical modelling, an understanding was developed of the relative relationships between various concepts (which had themselves emerged from an established theoretical framework of planning that had been further extended to accommodate the context of the present study). The study found that perceived time pressures actually showed a very low association with interview planning. Rather, investigators’ self-belief as to their own capability alongside workplace culture was each found to have stronger associations with investigators’ intentions to plan for their interviews. As such, we argue that there should be more focus on improving occupational culture relating to interview planning, while developing training programs that identify, evaluate, and enhance investigators’ planning skills. Implications for practice are therefore discussed.     

Assessment of Stress and Resiliency in Emergency Dispatchers

Although they are technically the first responders on most critical incidents, emergency dispatchers have received a modicum of attention from researchers and clinicians. The purpose of the present study was to evaluate job-related stress, psychological distress, posttraumatic stress disorder (PTSD), stress resiliency, and posttraumatic growth in this high-risk group. These areas were evaluated via an assessment battery administered to 90 emergency dispatchers working in a law enforcement agency. Results showed that dispatchers experienced an average amount of occupational stress, with 24% of the current sample reporting significant job stress. Between 13.34 and 15.56% reported symptoms consistent with a PTSD diagnosis, and 16.67% indicated sub-threshold PTSD symptomatology. The findings revealed that, overall, dispatchers experience occupational stress, psychological distress, and sub-threshold PTSD at similar or higher rates compared to police officers. Further, dispatchers reported posttraumatic growth at an average rate, also similar to that reported by police officers. Clinical implications of the results are discussed. Suggestions for directions that future research might take are offered.     

Analyzing Predictors of Drinking and Driving among Gender Cohorts within a College Sample

The current study focuses on predominant predictors associated with men’s and women’s engagement in driving under the influence (DUI) in an attempt to determine whether gender-specific interventions would be more affective at reducing impaired vehicle operation. A male-only subsample (n?=?863) and a female-only subsample (n?=?975) from a survey administered at a large Southeastern university containing self-reported measures of DUI were used to evaluate gender differences in motivations and correlates of DUI behavior. A series of logistic regressions containing indicators drawn from theories of deviant behavior (e.g., Akers’ social learning theory (SLT) and Gottfredson and Hirshi’s low self-control (LSC) theory) yield results indicating that differential association and imitation, both factors associated with SLT, are significant predictors for both gender cohorts’ DUI behavior. Low self- control was a significant predictor within female-only models, but not the final male-only models. This suggests that peer associations and modeling may be targets of intervention generally, but that, as it relates to DUIs, women may particularly benefit from programs focused at limiting impulsivity and risk-taking behavior as these are components of Gottfredson and Hirschi’s LSC construct.     

Massively parallel sequencing and the emergence of forensic genomics: Defining the policy and legal issues for law enforcement

Use of DNA in forensic science will be significantly influenced by new technology in coming years. Massively parallel sequencing and forensic genomics will hasten the broadening of forensic DNA analysis beyond short tandem repeats for identity towards a wider array of genetic markers, in applications as diverse as predictive phenotyping, ancestry assignment, and full mitochondrial genome analysis. With these new applications come a range of legal and policy implications, as forensic science touches on areas as diverse as ‘big data’, privacy and protected health information. Although these applications have the potential to make a more immediate and decisive forensic intelligence contribution to criminal investigations, they raise policy issues that will require detailed consideration if this potential is to be realised. The purpose of this paper is to identify the scope of the issues that will confront forensic and user communities.
