The purpose of this study is to gain a broad understanding of public perceptions of the police and violence.

This study uses survey data collected from a nationally representative sample (N = 1,223) by the National Opinion Research Center (NORC) Center for Public Affairs Research at the University of Chicago. Descriptive, bivariate correlational and multivariate regression analyses of the data were conducted.

Descriptive analyses show the populace is equally concerned about the police use of violence and violence against the police, but bivariate analyses indicate the two types of concern are unrelated, and multivariate regression analyses show that few variables impact both types of concern. Consistent with prior research, young people and racial/ethnic minorities reported greater concerns about police violence than did older adults and Whites, yet neither age nor race/ethnicity impacted concerns about violence against the police. Perceived mistreatment by the police was the only variable which impacted perceptions of police violence and violence against the police in a consistent and cogent manner.

This study is the first to examine public perceptions of the police as both the agents and victims of violence. The results indicate public perceptions of the police are more complex than was previously believed.

The purpose of this paper is to examine public perceptions of police efforts to control crime in South Korea.

The data were gathered from surveys administered to college students in the Seoul-Gyeonggi Province metropolitan area. Logistic regression analyses were performed to assess the impact of gender, fear of crime and perceived risk of victimization on diffuse and specific perceptions of police performance.

The respondents did not view the police favorably. Fewer than half the respondents reported that the police do a good job of controlling drunk driving, approximately a quarter reported that the police do a good job of controlling burglary and investigating homicide and roughly a fifth reported believing that the police effectively control crime. Violent victimization and fear of violent victimization had a significant negative impact on confidence in the police.

The data suggest that informing the public about the low risk of violent victimization and other publicity campaigns designed to reduce fear of violence may foster confidence in the police.

This study identifies subtle similarities and differences in the structure of public perceptions of the police between Eastern and Western nations. Additionally, the data indicate there is a need for greater specificity in measures of public perceptions of the police.

In the development of powder bed additive manufacturing (AM) process parameters, the characterization of mechanical properties is generally performed through relatively large mechanical test samples that represent a bulk response. This provides an accurate representation of mechanical properties for equivalently sized or larger parts. However, as feature size is reduced, mechanical properties transition from a standard bulk response to a thin wall response where lower power border scans and surface roughness have a larger effect.

For this study, samples of wall thickness varying between 4.0 and 0.25 mm were built in 304L on the selective laser melting (SLM) platform and Ti-6Al-4V on the electron beam melting (EBM) platform. Samples were then mechanically tested, and fractography was performed for analysis.

This study experimentally identifies the threshold between bulk and thin wall mechanical properties for 304L SS on the SLM platform and Ti-6Al-4V on the EBM platform. A possible method for improving those properties and shifting the transition from bulk to thin wall response to smaller wall thicknesses by manipulation of scan pattern was investigated.

This study is a novel investigation into the effect of reduced wall thickness on the mechanical properties of a part produced by powder bed AM.

The first part of this chapter addresses the history and development of the International Study Association of Teachers and Teaching (ISATT) and its engagement with the global educational community. We provide an account of the context and background against which ISATT developed as well as information about the founders’ orientations and the actions that led to ISATT’s birth. The second part of the chapter uses patterns of topic focus as graphic indicators of the evolution of ISATT’s research interests expressed through publication titles.

This research updates and expands upon Decker’s article “Citizen attitudes toward the police: a review of past findings and suggestions for future policy” by summarizing the findings from more than 100 articles on perceptions of and attitudes toward the police. Initially, the value of research on attitudes toward the police is discussed. Then the research pertaining to the impact of individual level variables (e.g. race) and contextual level variables (e.g. neighborhood) on perceptions of the police is reviewed. Studies of juveniles’ attitudes toward the police, perceptions of police policies and practices, methodological issues and conceptual issues are also discussed. This review of the literature indicates that only four variables (age, contact with police, neighborhood, and race) have consistently been proven to affect attitudes toward the police. However, there are interactive effects between these and other variables which are not yet understood; a finding which indicates that theoretical generalizations about attitudes toward police should be made with caution.

The purpose of this research was to assess public perceptions of the police in Mexico.

Surveys were administered to more than 300 law school students in Tampico, Tamaulipas.

Analyses of the data show that the majority of respondents view the municipal, state, and federal police forces negatively. The analyses also indicate that the federal police are viewed less negatively than the state police and the state police are viewed less negatively than the municipal police. Finally, the analyses show that there is a difference in diffuse and specific support for the police agencies, but there was not a consistent pattern of diffuse support being greater than specific support.

Because the sample was composed of law school students, the results cannot be generalized to the Mexican populace. And the unusual findings pertaining to diffuse and specific support for the police indicate a need for additional research on this phenomenon.

The findings suggest that the recent police reforms in Mexico have failed to instill public confidence in the police and that the Mexican government needs to increase police reform efforts. In addition, because of the large influx of immigration from Mexico into the USA, police agencies in the USA will need to increase efforts to work with Hispanic communities in order to gain the confidence of the Mexican immigrants.

To date, this is the most comprehensive empirical examination of perceptions of the police forces in Mexico.

Kevin McRider, the COO of a fledging research facility, needed to foster an environment where scientists explored the boundaries of the metals, chemicals, polymers and tools used to create innovating medical devices. The freshly-minted PhDs he hired were enthusiastic to design and conduct research projects that bridged their scientific disciplines, in a collaborative workplace, with time allocated to individual projects as well. Effectively managed, their research would help the parent corporation leapfrog over existing or near-future technology.

The problem for McRider was how to get Lintell to realize his vision of a collaborative organizational culture that promoted revolutionary scientific discoveries. His challenges included managerial behaviors that prohibited critical interaction and information sharing, as well as disruptive organizational dynamics he himself had set in motion including pressures to focus only on certain research goals and projects at the expense of creative exploration, and the violation of the psychological contracts McRider himself had created with the scientists during recruitment.
