Experiencing impartiality to invoke fairness in the n-PD: Some experimental results

Subjects play a 5-person Prisoner's Dilemma both from an impartial point of view and in a regular fashion to determine whether 1) Concerns for fairness increase cooperative behavior; 2) Play of a Prisoner's Dilemma from an impartial point of view results in significantly higher levels of cooperation than does normal play; 3) Concern for fairness has greater explanatory force in explaining cooperation in impartial plays of the Prisoner's Dilemma than in normal plays; and 4) Experience with impartial play of a Prisoner's Dilemma sensitizes subjects to normative imperatives and results in higher levels of cooperation in subsequent normal plays of Prisoner's Dilemmas. The first and second hypotheses are supported, the third is inverted, and the fourth is not supported. Concern for fairness is demonstrated to play a complex role in explaining cooperative behavior in regular plays of the game. An earlier version was presented at the Annual meetings of the Public Choice Society, 1993 Monteleone Hotel, New Orleans; 20 March 1993.     

When lawyers question children

This study assessed the impact of some complex question forms frequently used by attorneys who examine and cross-examine witnesses in the courtroom. Fifteen males and 15 females from each of four student populations (kindergarten, fourth grade, ninth grade, and college) viewed a videotaped incident and then responded to questions about the incident. Half the questions were asked in “law-yerese” (i.e., using complex question forms); the remaining half asked for the same information using simply phrased question forms of the same length. Lawyerese confused children, adolescents, and young adults alike. Questions that included multiple parts with mutually exclusive responses were the most difficult to answer; those that included negatives, double negatives or difficult vocabulary also posed significant problems. Results suggest that complex question forms impede truth-seeking and should be prohibited in court.     

Economic Voting and Multilevel Governance: A Comparative Individual-Level Analysis

An important component of incumbent support is the reward/punishment calculus of economic voting. Previous work has shown that "clarity of responsibility" within the central state government conditions national economic effects on incumbent vote choice: where clarity is high (low), economic effects are greater (less). This article advances the "clarity of responsibility" argument by considering the effect of multilevel governance on economic voting. In institutional contexts of multilevel governance, the process of correctly assigning responsibility for economic outcomes can be difficult. This article tests the proposition that multilevel governance mutes effects of national economic conditions by undermining responsibility linkages to the national government. Individual-level data from the Comparative Study of Electoral Systems Module 1 are used to test this proposition. Results demonstrate that economic voting is weakest in countries where multilevel governance is most prominent. Findings are discussed in light of the contribution to the economic voting literature and the potential implications of multilevel governance.     

The efficiency of an X-ray screening system at a mass disaster

This is a study to determine the efficiency and efficacy of using an X-ray security screening system to locate both dental fragments and other foreign objects that might be commingled with fragmented remains in a mass disaster. A controlled study by the Pennsylvania Dental Identification Team (PADIT) revealed that a manual examination of simulated body bags containing commingled dental parts and foreign objects by a team of trained forensic odontologists was very effective in locating dental fragments and in finding foreign objects. Although this was effective, it was not efficient, because it was very time consuming. With the use of an X-ray security screening system, the time factor could be reduced. This study also revealed that even though this sophisticated equipment could reduce the time factor in locating commingled dental and foreign objects, a forensic odontologist should be utilized to be most effective.     

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.     

Do graduated university incubator firms benefit from their relationship with university incubators?

Business incubators have become a popular policy option and economic development intervention tool. However, recent research shows that incubated firms may not benefit significantly from their incubator relationships, and may even be more vulnerable to failure post departure (graduation) from an incubator. These findings suggest that the impact of business incubation on new venture viability may be contingent on the type of support offered by an incubator and attributes of business environments within which incubation services are provided. Incubation services that protect and isolate ventures from key resource dependencies may hinder venture development and increase subsequent vulnerability to environmental demands. Alternatively, incubation services that help ventures connect and align with key resource dependencies are likely to promote firm survival. We propose that incubators vary in the services and resources they offer, and that university incubators typically provide greater connectivity and legitimacy with respect to important contingencies associated with key industry and community stakeholders. This leads us to propose that university affiliation is an important contingency that affects the relationship between firms’ participation in incubators and their subsequent performance. The purpose of this study is to evaluate this contingency by examining whether firms graduating from university incubators attain higher levels of post-incubation performance than firms participating in non-university affiliated incubators. We test this by evaluating the performance of a sample of graduated firms associated with the population of university-based incubators in the US contrasted against the performance of a matched cohort of non-incubated firms. The analysis uses an enhanced dataset that tracks the number of employees, sales, and the entry and graduation (departure) points of incubated firms from a university incubation program, so as to delineate the scope of influence of the incubator.     

Key Risk Factors for Relapse and Rearrest Among Substance Use Treatment Patients Involved in the Criminal Justice System

Substance use treatment programs for criminal justice populations have great potential for crime reduction, if they can effectively manage patients’ risk for relapse and rearrest. The current study used data drawn from the Comprehensive Assessment and Treatment Outcome Research (CATOR) system, a national registry of substance use treatment programs, which collected patient outcome data at 6- and 12-month intervals following discharge from treatment. The primary objective was to examine sets of factors that may compromise relapse and rearrest outcomes among patients who were court mandated to participate in treatment. Findings demonstrated that patients’ clinical severity of substance use was associated with relapse, which also significantly increased the probability of post-treatment arrest. Adolescent risk behaviors represented another set of risk factors, particularly among patients who experienced the most severe pattern of relapse and arrest outcomes. Additionally, demographic risk factors, including age, marital status (i.e., single or unmarried relative to married), employment (i.e., being unemployed compared to employed), and lower educational attainment were consistently linked to higher probabilities of relapse and rearrest. Treatment programs for criminal justice populations should consider incorporating appropriate clinical risk assessment measures, behavioral risk assessments, and appropriate employment interventions into standard treatment programming in an effort to improve outcomes.
