Building group capacity for problem solving and police–community partnerships through survey feedback and training: a randomized control trial within Chicago’s community policing program

Objectives

To examine whether group capacity for problem solving and partnership building could be enhanced at police–community meetings by providing the results from community surveys and training for group facilitators.

Methods

A randomized control trial was conducted in 51 police beats in Chicago’s community policing program, CAPS. Unlike control beats, results from web-based community surveys were provided at beat meetings in the feedback and training beats, with facilitators in training beats also receiving training and exercises to guide problem solving about survey results. Analysis included OLS and logistic regression of data from questionnaires administered to police and resident participants, as well as observations at beat meetings, which measured resident capacity, attitudes about the police–community partnership, and problem-solving activities.

Results

Support for hypothesized effects was found with greater resident confidence in their ability to achieve outcomes and solve local problems, as well as officers viewing their relationships with residents at beat meetings more favorably. Effects, however, were inconsistent and limited to the feedback group. While additional training and support provided in training beats indicated fuller engagement in problem solving, possible negative effects on attitudes were observed.

Conclusions

Failure to find more effects is discussed in terms of implementation and resistance. Officer resistance to and a shift in organizational priorities away from community policing worked against achieving full program implementation. The beat meeting context provided a traditional framework for police–resident interactions that precluded more comprehensive use of community data and possibly heightened dissatisfaction with the level of problem solving that occurred.     

Real interest rate persistence in South Africa: evidence and implications

The real interest rate is a very important variable in the transmission of monetary policy. It features in vast majority of financial and macroeconomic models. Though the theoretical importance of the real interest rate has generated a sizable literature that examines its long-run properties, surprisingly, there does not exist any study that delves into this issue for South Africa. Given this, using quarterly data (1960:Q2-2010:Q4) for South Africa, our paper endeavors to analyze the long-run properties of the ex post real rate by using tests of unit root, cointegration, fractional integration and structural breaks. In addition, we also analyze whether monetary shocks contribute to fluctuations in the real interest rate based on test of structural breaks of the rate of inflation, as well as, Bayesian change point analysis. Based on the tests conducted, we conclude that the South African EPPR can be best viewed as a very persistent but ultimately mean-reverting process. Also, the persistence in the real interest rate can be tentatively considered as a monetary phenomenon.     

Perceived Quality of Life and Health Complaints in Children Exposed to Intimate Partner Violence

Children 9 to 13 years old exposed to intimate partner violence (IPV) reported on their violence exposure, attachment to both parents, temperament (negative emotionality and emotion regulation), perceived quality of life, and health complaints. Half of the children perceived their quality of life as good and did not have recurrent health complaints. When controlling for socioeconomic status, health complaints were associated with higher IPV exposure and negative emotionality, whereas quality of life was associated with attachment security, higher capacity for emotion regulation, and lower negative emotionality. These results underscore the importance of increasing and supporting the capacity of children exposed to IPV to handle and express their emotions, as well as making school nurses and other primary care practitioners more attentive to IPV as a possible background factor in children’s health complaints.     

Navigating the role of the principal investigator: a comparison of four cases

Principal investigators are the lead actors on projects at the forefront of nascent technologies, yet few studies have explored the personal actions and experiences of PIs as they navigate their roles. I investigated principal investigators and their approach to new boundary spanning and entrepreneurial roles. Following a multiple case study methodology with a combination of interviews and observation, four PIs in nanotechnology related fields are explored in three dimensions: career and institutional alignment, boundary spanning activities and the tensions created in the still largely uncharted waters of nanotechnology commercialization. I found that these PIs actively sought organizational alignment that allowed them “to make things happen” while keeping harmony between the university and enterprise. The PIs demonstrated boundary-spanning activities, in particular a propensity for welcoming strangers into their labs in the hopes of finding new knowledge and opportunities, and practicing “good grantsmanship” to convert these new relations into collaboration. I found that the PIs managed tensions related to academic progression and lack of institutional support. Through this study, I offer researchers an opportunity to hear the voice of PIs on these topics and seek to contribute to our understanding of PIs as critical actors in the pursuit of science.     

Academic outcomes among principal investigators,co-principal investigators,and non-PI researchers

Faculty at research universities are evaluated on a number of productivity measures including their ability to conduct research, teach, and engage in service. Research outcomes include publishing research results and acquiring grants and contracts to conduct additional research. While it is assumed that researchers who are awarded grants are more likely to publish research results, there is little research investigating the ways in which grants affect outcomes or how principal investigators differ from researchers who do not hold research grants or those who are co-principal investigators. This research seeks to understand if principal investigators are more or less productive than co-principal investigators and those who do not have grants, and if so, what explains that variation in productivity. It also examines whether women PIs are more or less productive than men PIs. This research uses longitudinal data drawn from an NSF funded survey of academic scientists in Carnegie-designated Research I universities in six fields: biology, chemistry, computer science, earth and atmospheric sciences, electrical engineering, and physics. From this national random sample of men and women scientists and engineers we investigate whether there is variation in the production of outcomes (e.g. publications, teaching, and training graduate students) among PIs, co-PIs, and other researchers. Findings show that productivity and outcomes vary significantly for PIs, co-PIs and by sex.     

Too big to fail,too powerful to jail? On the absence of criminal prosecutions after the 2008 financial meltdown

Various explanations have been offered regarding the causes of the current global economic crisis that was spawned by the collapse of mortgage-based securities in the U.S. that were sold world-wide and that contained "toxic assets" comprised of subprime loans. There is ample evidence that such loans were originated through fraud. Firms recorded huge profits, and executives were awarded large bonuses even though some had led their companies into bankruptcy and plunged both the U.S. and global economies into the greatest recession since the Great Depression. This paper assesses the reasons why there have been no major prosecutions to date, and compares the U.S. government's response to that in the savings and loan crisis. It analyzes the influence of large financial institutions on lawmaking, regulation, and the allocation of enforcement resources, the continued general lack of understanding of financial fraud including control fraud, and problems related to the higher status and power of potential defendants.     

What's mine is mine and what's yours is mine too: Converging U.S. intellectual property exhaustion doctrines

With the increasing dispersion of intellectual property comes the intellectual property rights owner's continued desire to retain that part of the equation for which the bargain was struck. In terms of patents, the patentee strikes a deal to disclose the invention to the public in exchange for a monopoly over its use for a limited term. Copyright holders contribute their works to the intellectual pool receiving value by sale, lease or license. In 2012–13, the U.S. Supreme Court was tasked with delineating the realms of two intellectual property exhaustion doctrines and answering the question of where to draw the line with regard to an IP owner's ability to control the protected invention or work via patent or copyright, respectively. In one case, the Court permitted the intellectual property owner to restrict a subsequent purchaser's use of the product subject to protection, while in the other case the Court rejected the intellectual property owner's attempt to control the downstream use or resale of the product. This article discusses the relevant intellectual property exhaustion doctrines, analyzes and reconciles the Court's decisions in these cases, and provides guidance for navigating restrictions on use of U.S. protected products and works around the globe.     

Positive Effects in Detecting Lies from Training to Recognize Behavioral Anomalies

We examined whether training in both the verbal and nonverbal indicators of truth telling and lying would have positive effects on Law Enforcement Officers’ (LEOs) ability to evaluate truths from lies. College course-level training on empirically validated verbal and nonverbal indicators of truth telling and lying was provided to mid- to advanced-career level LEOs, whose accuracy in detecting lies from truths was assessed pre- and post-training using truthful and deceptive videos of mock crimes and opinions. A marginally significant truth bias existed at pre-test; training, however, resulted in a significant improvement in accuracy rates for both truth and lie videos, and the truth bias that existed at pre-test was eliminated. Additional analyses indicated that accuracy rates improved for videos of mock crimes but not for opinions. These findings add to a small but growing literature that indicates that training on validated verbal and nonverbal indicators of truth telling and lying has positive benefits.     

The states "race" with the federal government for stem cell research

This article presents an innovative study of the effect of individual states and private institutes in pushing forward stem cell research despite a federal ban on creating new stem cell lines. The author analyzes the impact of state legislation, proposing that states are reacting to federal policy by serving as laboratories for what is traditionally federally funded biomedical research.     

Genotyping for DQA1 and PM loci in urine using PCR-based amplification: effects of sample volume, storage temperature, preservatives, and aging on DNA extraction and typing.

Urine is often the sample of choice for drug screening in aviation/general forensic toxicology and in workplace drug testing. In some instances, the origin of the submitted samples may be challenged because of the medicolegal and socioeconomic consequences of a positive drug test. Methods for individualization of biological samples have reached a new boundary with the application of the polymerase chain reaction (PCR) in DNA profiling, but a successful characterization of the urine specimens depends on the quantity and quality of DNA present in the samples. Therefore, the present study investigated the influence of storage conditions, sample volume, concentration modes, extraction procedures, and chemical preservations on the quantity of DNA recovered, as well as the success rate of PCR-based genotyping for DQA1 and PM loci in urine. Urine specimens from male and female volunteers were divided and stored at various temperatures for up to 30 days. The results suggested that sample purification by dialfiltration, using 3000-100,000 molecular weight cut-off filters, did not enhance DNA recovery and typing rate as compared with simple centrifugation procedures. Extraction of urinary DNA by the organic method and by the resin method gave comparable typing results. Larger sample volume yielded a higher amount of DNA, but the typing rates were not affected for sample volumes between 1 and 5 ml. The quantifiable amounts of DNA present were found to be greater in female (14-200 ng/ml) than in male (4-60 ng/ml) samples and decreased with the elapsed time under both room temperature (RT) and frozen storage. Typing of the male samples also demonstrated that RT storage samples produced significantly higher success rates than that of frozen samples, while there was only marginal difference in the DNA typing rates among the conditions tested using female samples. Successful assignment of DQA1 + PM genotype was achieved for all samples of fresh urine, independent of gender, starting sample volume, or concentration method. Preservation by 0.25% sodium azide was acceptable for sample storage at 4 degrees C during a period of 30 days. For longer storage duration, freezing at -70 degrees C may be more appropriate. Thus, the applicability of the DQA1 + PM typing was clearly demonstrated for individualization of urine samples.
