Rent-seeking with non-identical sharing rules: An equilibrium rescued

Nitzan's (1991) analysis of differential sharing rules in a collective rent-seeking setting is reconsidered. Two groups, each with more than one member, are presumed to use different linear combinations of two sharing rules, one based on an equal-division of the prize, and the other on each member's relative effort. We show that an equilibrium always exists for this type of game, and then characterize the equilibrium. Our result is contrary to Nitzan's claims that (a) in the general case an equilibrium often does not exist, and (b) an equilibrium never exists when the groups use the polar extreme rules.     

Knowing When to Salute

Due to a strong “Can Do” spirit and a well-engrained, albeit simplistic, notion of civilian control over the military, senior military leaders are disinclined to publicly share their disagreement with emerging national security policy. Many senior officers mistakenly believe that there are no alternatives other than just silently executing, resigning, or retiring when confronted with bad policy formulation. There are, however, options available to senior uniformed leaders when confronted with policy formulation that they, in their professional opinion, believe is flawed. Depending on the degree to which the civilian authorities are receptive to military advice and the magnitude of the threat to national security involved in the policy, senior military leaders can choose among many alternatives to widen the policy debate.     

Presidential address: From the Great Society to continuous improvement government: Shifting from “does it work?” to “what would make it better?”

In the 1960s, various social programs were started (like Head Start) or dramatically expanded (like AFDC). Loosely, this period of expansion is called the Great Society. Too many Great Society social programs, unfortunately, have been disappointments—at least when compared to the high hopes of the '60s. Even if they “work,” most of us wish that they worked much better. Some people take such statements to mean that the Great Society's social programs should be defunded. Most Great Society programs, however, are surely here to stay, for they serve important social functions. How many of us really think there could be an America without a social safety net? It is now time to do the difficult and unglamorous work of systematic program improvement. Instead of testing program efficacy over and over again, we should engage in ongoing and evidence‐based efforts to increase program effectiveness (in both large and small ways). © 2009 by the Association for Public Policy Analysis and Management.     

外国留学生在中国主流大学的文化适应--超越留学生公寓

随着全球化的加剧,2004年在中国留学的外国留学生已经增到11万人,而且这一趋势在随后的几年内还会进一步增强.这就使得中国的大学面临着一个巨大的挑战,即如何在本地学生与外国学生平等互惠的条件下,使日益增长的外国留学生更好地适应中国主流大学的文化.面对这一问题,中国的大学需要在首次联系、校园、工作人员、教室、学生五个方面加强工作和投入,而对这些目标的实施,实际上就反映了21世纪跨文化交流的主要经验,即让学生比较容易发现到国外留学的机会,热情、友好地欢迎国外留学生,有严格的学术要求和原则,使外国留学生与本国学生之间在校园内外能密切的互动和交流,创造一个互惠互利的双赢局面.     

Stereotypes influence beliefs about transfer and sentencing of juvenile offenders

Despite sharp drops in juvenile crime since the mid-1980s, punitive policies regarding juveniles who commit serious offenses still exist. We assessed beliefs about two such practices: transferring offenders from the juvenile justice to the criminal justice system, and subjecting them to sentences of life without parole (LWOP). We examined whether stereotypes about juvenile offenders – the extent to which people believe they are dispositionally violent superpredators versus economically and socially impoverished wayward youth – influence support for these policies. We measured 321 participants’ beliefs about the causes of juvenile crime and juveniles’ potential for recidivism and rehabilitation. Using vignette methodology and actual case facts, we described a 13-, 17-, or 21-year-old offender who murdered a stranger or abusive parent, and asked whether he should be transferred to criminal court and sentenced to LWOP. As endorsement of the superpredator stereotype increased, so did support for these practices. Offenders who murdered an abusive parent were shown more leniency. Older offenders were generally treated harsher, except by people with strong superpredator stereotypes who, on the issue of LWOP appropriateness, did not distinguish among juveniles of different ages. Findings suggest that stereotypes can influence judgments in cases involving juveniles and indirectly affect policy-making about juvenile offending.     

Problems and service needs among ex-offenders with HIV risk behaviors entering sober living recovery homes

There is currently a nationwide effort to decrease the number of persons who are incarcerated in jails and prisons. However, many ex-offenders on probation or parole do not have access to affordable housing and larger proportions have histories of HIV risk as well as substance abuse problems. In California, sober living houses (SLHs) are becoming an increasingly popular housing option for these individuals. Based largely on the principles of alcoholics anonymous, SLHs require abstinence from alcohol and drugs and provide peer support for recovery. The current study examined the types of problems experienced among 330 ex-offenders with lifetime risk for HIV during the six months prior to entering SLHs. Nearly three fourths (74%) of all ex-offenders entering the houses had at least one HIV risk. The importance of housing was evident in the finding that housing status and participants’ perceptions of their housing situation were associated with a variety of problem areas, including substance use, HIV risk, psychiatric severity, and legal problems. SLHs represent an important housing option for ex-offenders, but many residents may need additional services to address various problems.     

Assessing the Feasibility and Acceptability of Narrative Exposure Therapy to Address IPV-related Mental Health in Parenting and Pregnant Adolescents

Many urban, low-income adolescents experience violence, often resulting in posttraumatic stress disorder (PTSD) and depression. Narrative Exposure Therapy (NET) facilitates therapeutic processing of traumatic memories. This purpose of this study is to examine the feasibility of NET among adolescents at-risk for PTSD and depression. Two community-based agencies hosted five focus groups with adolescents (n = 28), aged 18–21, predominantly African- American (71 %) and female (61 %) and one with adolescent service providers (n = 11). Pope’s coding framework (2000) and the Socio-Ecological Model for violence prevention (Krug et al. in The Lancet, 360(9339), 1083–1088, 2002) elicited perceived barriers and facilitators to NET. Individual, relationship, and community level barriers and facilitators to NET therapy engagement were identified. The findings indicate participants have favorable attitudes about NET and the provision of the therapy within trusted community agencies. The results will inform the next steps of NET implementation, training, and psychoeducation.     

The impacts of the Virginia Tech and Northern Illinois University shootings on fear of crime on campus

There has been a substantial increase in the number of mass shooting incidents on college campuses in the United States in recent years. Although empirical research examined the impacts of secondary school shootings on student fear, there have been no comparable studies of the impacts of campus shootings. This study began to fill this void by examining responses to surveys administered to convenience samples of students enrolled at the University of South Carolina prior to and following the mass shooting incidents on the campuses of Virginia Tech and Northern Illinois University. Findings indicated that both shootings were associated with modest increases in various measures of fear. Other findings were that the impacts of the shootings depended on both the type of fear measured (e.g., general fear versus fear of being a victim of specific crimes) and student characteristics such as age, sex, and race.     

The forensic evaluation of burned skeletal remains: A synthesis

In recent years, research and case experience have greatly augmented knowledge regarding the effects of extreme heat on skeletal remains. As a result of this effort, enhanced interpretation is now possible on such issues as the extent of recovery, reconstruction, trauma, individual identification, size reduction, thermal effects on histological structures, color variation, the determination if remains were burned with or without soft tissue, DNA recovery and residual weight. The rapidly growing literature in this area of forensic science includes experimental research that elucidates the dynamics of the thermal impact on skeletal structure and morphology.     

Effect of Sterilants on Amplification and Detection of Target DNA from Bacillus cereus Spores

To conceal criminal activity of a bioterrorist or agroterrorist, the site of pathogen generation is often treated with sterilants to kill the organisms and remove evidence. As dead organisms cannot be analyzed by culture, this study examined whether DNA from sterilant‐treated Bacillus cereus spores was viable for amplification. The spores were exposed to five common sterilants: bleach, Sterilox®, oxidizer foam (L‐Gel), a peroxyacid (Actril®), and formaldehyde vapor. The spores were inoculated on typical surfaces found in offices and laboratories to test for environmental effects. It was found that the surface influenced the efficiency of recovery of the organisms. The DNA isolated from the recovered spores was successfully detected using RT‐qPCR for all treatments except for formaldehyde, by amplifying the phosphatidylinositol phospholipase C and sphingomyelinase genes. The results demonstrated that evidence from sites treated with sterilants can still provide information on the uncultured organism, using DNA amplification.
