The effect of school classroom characteristics on low self-control: A multilevel analysis

Gottfredson and Hirschi's general theory has reaped a substantial amount of empirical support. Recently, attention has focused on the factors associated with the development of self-control. With few and isolated exceptions, most research has examined the ways in which parents contribute to the development of self-control in children. Gottfredson and Hirschi hypothesized, however, that other social institutions, especially schools, may play at least some role in inculcating self-control. The current study addressed this possibility by conducting a series of multilevel models that examined whether the characteristics of schools, and classrooms within schools, were salient to the development of self-control. Using a longitudinal sample of kindergarten and first-grade students, the results revealed that classroom characteristics influenced self-control.     

Incidental findings in genetics research using archived DNA

Despite calls by some commentators for disclosing incidental findings in genetics research, several factors weigh in favor of caution. The technology of genetics has the power to uncover a vast array of information. The most potent argument for restraint in disclosure is that much research is pursued without consent so that the individual participant may not know that research is being conducted at all. Often the work is done by investigators and at institutions with which the person has no prior contact. Past practice is also relevant; genetics researchers historically have chosen not to disclose incidental findings, of which misattributed paternity and pleiotropic alleles such as ApoE have been the most common. Many people choose not to have genetic tests when given a choice. It may be desirable to discuss the topic of incidental findings when consent for research is obtained, but given the risk of unwanted surprise when there has been no prior discussion, the potential utility of incidental findings should be very high before they are even offered to individuals.     

The power of protest on policing: Black Lives Matter protest and civilian evaluation of the police

In 2020, police brutality against Black Americans catalyzed Black Lives Matter (BLM) protests across all 50 states. Though BLM protests continue to permeate society, few scholars explore how these protests change Americans' perceptions of the police. To investigate this phenomenon more meticulously, we administered an online survey experiment—oversampling Black American participants—to measure how protest culture, specifically BLM protests, influences civilians' perceptions of the police. Our survey found that (1) Black American participants have a lower evaluation of police performance, but a higher evaluation of the BLM Movement than White American participants; (2) the presence of a general protest negatively impacts peoples' perception of safety, police trustworthiness, and police performance; and (3) a BLM protest casts a stronger effect on White American participants than on Black American participants. Using Critical Race Theory and QuantCrit these findings suggest that the visibility of BLM protests changes both Black and White perceptions of the police to varying degrees.     

Evaluating City Financial Management Using Fuzzy Rule—Based Systems

Financial management is one of the most important management tasks of government. The complexity of financial management systems has discouraged overall evaluations of financial management. The objective of this article is to develop a method for evaluating government financial management that can handle this complexity. A fuzzy rule–based system (FRBS) is a methodology that can use many different types of data, produce robust input measures and can capture the complex contextual judgment of experts. Using data collected as part of the Government Performance Project survey of large cities, we develop an FRBS for city financial management.     

A validation study for vinyl electrical tape end matches

Fracture matches are considered the strongest conclusion in the forensic examination of rigid materials, such as glass, metal, and paint. However, publications that support the fracture matching of polymeric films, such as tape backings, are limited. This study was designed to determine the validity and error rate associated with conducting end-match (fracture match) examinations on vinyl electrical tape. Test designs varied the source roll of tape, test preparer, or mode of separation from the roll. Results indicated that each affected the resulting severed tape ends. The analysts examining the end matches also had an effect on the results. Eight end matches in the study were not identified by the initial analysts and were considered inconclusive. One end match was misidentified, resulting in one false positive and an error rate of 0.049%. These results support a comprehensive physical and chemical tape comparison regardless of indications of an end match.
