ARPA-E and DARPA: Applying the DARPA model to energy innovation

ARPA-E offers a new innovation institutional model to meet energy technology challenges. Because it is explicitly based on DARPA, this article reviews the noted DARPA approach in detail. Briefly citing well-known features of DARPA, it explores a number of important features that have not been well discussed in the policy literature on DARPA. These include DARPA??s ability to undertake multigenerational technology thrusts, the synergies it has been able to create through complementary strategic technologies, its ability to build an advocate community, and connections it has built to larger innovation elements downstream from DARPA. It has also taken on incumbent technologies within both DOD and in the private sector, used ties to DOD leadership to press its advances, and supported initial market creation. The article then reviews the new ARPA-E model in detail, commenting first on how ARPA-E has adopted key DARPA approaches. It then discusses new features ARPA-E is adopting, driven by the unique demands of the complex, established energy sector. These include new ways: (1) to sharpen the research visioning, selection and support processes, (2) to build a community of support, important to its political survival, and (3) to implement technologies it supports. In addition, the further DARPA features enumerated above provide potentially useful future guideposts to ARPA-E. The paper closes with a discussion of the difficult technology implementation problems on the ??back end?? of the innovation system??including demonstrations, test beds, and initial markets. The article posits that both agencies must further address these implementation issues by fostering additional downstream partnerships, including between government and private sector.     

Variation in Adult and Juvenile Arrest Rates: The Influence of City Size and Metropolitan Environment

Since the mid-1990s, the index crime rate has steadily decreased while the rate for Part II offenses has increased. The current study examines these differences from 1990 to 2004 using arrest rate data from the 35 largest cities in the state of Texas. Cluster regression analyses is employed to examine the effect of city size and city location, whether the city is part of a larger metropolitan area or “stand-alone,” to explain variation in juvenile and adult arrest rates by category of offense (violent, property, Part II) while controlling for the influence of social disorganization variables. Findings indicate that differences exist in the arrest rates for almost all types of offenses in mid-size versus very large cities. Contrasting adult versus juvenile arrest rates, city size and city location offer limited explanation for variation over time. Implications of these findings are discussed in the context of suggested policy and research directions.     

Investigation of a typology of alcohol‐related violence defined by ultimate goals

Purpose. Alcohol‐related violence is a serious problem and treatments for high‐risk individuals need to be developed. Classification helps to route people into appropriate treatments. Drawing on animal research, we define alcohol‐related violence in relation to ultimate goals. We propose three types of violence: (1) violence in the pursuit of material goals, (2) violence in pursuit of social dominance goals, and (3) violence as defence in response to threat. The aim is to explore factors that we expect to relate to this tripartite typology, with the aim of providing a preliminary validation. Method. Participants were 149 young male prisoners who had committed an offence of violence that was alcohol related. Semi‐structured interviews elicited information about the offence that enabled classification into one of the three types. Differences between groups were examined at the event level – level of violence during the offence and alcohol consumption before the offence – and at group level – trait aggression, trait anxiety, anger control, and alcohol–aggression outcome expectancies. Results. No differences were found in levels of violence or alcohol consumption. Those whose violence was in the pursuit of material goals were high on trait aggression, trait anger, trait anxiety, and anger suppression. Those who used violence in the pursuit of social dominance showed high trait aggression and trait anger. Those whose violence was a defence in response to threat showed lower trait aggression and trait anger. Conclusion. The findings are discussed in relation to differential group profiles and treatment needs.     

Social Deprivation as Tempting Fate

Two recent discussions concerning punishment of the socially deprived reach conflicting conclusions. Andrew von Hirsch and Andrew Ashworth argue that we should sympathize with the predicament of the poor and therefore mitigate their sentences. Peter Chau disputes von Hirsch and Ashworth’s conclusion, contending that having to face strong temptations is not an appropriate ground for reducing anyone’s punishment for their crimes. I argue that neither von Hirsch and Ashworth’s account nor Chau’s critique of it is persuasive. I then take up the challenge of showing why social deprivation renders punishment problematic. I contend that it establishes a perverse incentive structure that is persistent and powerful, requiring the disadvantaged to exercise self-control on an ongoing basis. Repeated acts of self-control are difficult, especially for youths whose skills at it are not yet fully developed. Also, in a variety of more and less subtle ways, social deprivation reduces the incentives for self-control and may work to stunt its development. In closing, I briefly consider the options for responding to the crimes of the chronically disadvantaged.     

A Commentary on the MND Model and the Boone Critique: “Saying It Doesn’t Make It So”

We appreciate Boone’s (2011, this issue) critique of Rogers, Bender, and Johnson’s (2011, this issue) analysis of the Malingered Neurocognitive Dysfunction (MND) criteria. She raised good points and appeared in general agreement regarding several crucial limitations of the MND model. However, Boone remained mostly silent on several issues including the compelling results from our methodological review of MND studies and Criteria A through D. When provided, her comments tended to be very selective and were often presented with little or no empirical support. This contrasting pattern of strong statements and weak evidence appears to unintentionally parallel the MND model, which was documented in our original analysis. As a result of her criticism, however, we clarified our point regarding methodological limitations in establishing levels of TBI and its potential relevance to determinations of feigned cognitive impairment. We hope that these spirited discussions will stimulate a much-needed review and a fundamental revamping, if not replacement, of the MND model.     

Substance use among African American adolescents in the Midwest

The purpose of this article is to examine the attitudes and substance use behaviors of African American adolescents living in the Midwest. A baseline survey was administered to 463 African American teens between the ages of 11-19. The article examines the relationship between attitudes toward drugs and drug-using behavior in this African American sample. Drug use will be compared to national drug use norms established by the Youth Risk Behavior Surveillance Survey. Overall participants had fairly negative attitudes toward drugs. Sixty percent of the sample reported that they were committed to a drug-free life, 74% had made a decision to stay away from marijuana, 79% reported making a decision not to smoke cigarettes, and 71% reported they would not get drunk in the next year. Females were more likely to stay away from marijuana than males. In this current study there is cause for alarm; participants reported higher percentages of ever smoking cigarettes and marijuana than the Youth Risk Behavior Surveillance Survey. This study shows there is a need to provide substance abuse prevention programs for African American adolescents. Limitations and future directions are also discussed.
