Racial Differences in Resolving Conflicts: A Comparison between Black and White Police Officers.

Ivan Y. Sun; Brian K. Payne

This study examined the behavioral differences between Black and White police officers in handling interpersonal conflicts. Observational and survey data from the Project on Policing Neighborhoods and the 1990 census data were used. Actions taken by officers are examined along two behavioral dimensions: coercion and support. Findings show that Black officers are more coercive than their White counterparts in responding to conflicts. Black officers are also more likely than White officers to conduct supportive activities in predominantly Black neighborhoods, whereas they do not differ in initiating supportive actions in racially diverse communities. Situational characteristics play a strong role in determining police actions during conflict resolution. Implications for policy and future research are discussed.

Citizen Trust in Police: The Case of China

Yuning Wu; Ivan Y. Sun

This study assesses the extent to which Chinese citizens trust their police and explores factors that account for variation in public trust in police. Very few studies have empir ically examined Chinese attitudes toward police. Using conflict theory as the guiding theo retical framework and interview data collected from eight Chinese cities, the study tests the effects of conflict variables, including gender, age, education, income, employment, and perceived political influence, and relevant control variables on Chinese public trust in police. The results show that conflict variables only have a modest explanatory power o Chinese attitudes toward police. Younger Chinese and Chinese with lower levels of per ceived political power tend to have lower levels of trust in police. Chinese attitudes toward police are also influenced by satisfaction with public safety, governmental capability of dealing with crime, quality of life, and corruption among government officials Implications for future research are discussed.

Institutional Strength, Social Control and Neighborhood Crime Rates:

Ruth Triplett; Randy R. Gainey; Ivan Y. Sun

While the systemic model that todays theories of social disorganization are based on acknowledges that neighborhood-based institutions may vary in their ability to contribute to effective social control, relatively little attention has been given to their role in understanding neighborhood rates of crime. At the same time, there is contradictory evidence about the role of social networks, which have been the focus of much research attention. This article builds upon past work to present a model of neighborhood-based institutional social control to address this lack of attention. The model centers on a conceptualization of institutional strength that distinguishes between the dimensions of institutional strength, and the causes and effects of variation in institutional strength.

Race, Immigration, and Policing: Chinese Immigrants’ Satisfaction with Police

Yuning Wu; Ivan Y. Sun; Brad W. Smith

A considerable body of research focuses on racial and ethnic minorities’ perceptions of police, yet non-Black, non-Hispanic minority groups, Asians in particular, are largely overlooked. Meanwhile, despite a fast growing immigrant population and the increasing demand on local police to enforce immigration law, research on police–immigrant relations remains limited. Using data from over 400 Chinese immigrants, this study examines the issues of race/ethnicity, immigration, and policing with a focal concern on Chinese immigrants’ attitudes toward police. Results indicate that the majority of Chinese immigrants rate police positively in overall performance and specific areas of effectiveness, integrity, and demeanor. Both universal and immigrant-specific factors are important predictors of immigrants’ attitudes. Chinese immigrants’ evaluations of police are not only affected by exposure to media coverage of police misconduct, neighborhood conditions, and city context, but also are intertwined with their opinions of their home country police and perceptions of US immigration authorities.

Chinese Policing in a Time of Transition, 1978-2008

Ivan Y. Sun; Yuning Wu

This article examines the development of policing in China over several historical periods. It consists of three major parts. The first section provides a brief historical review of Chinese policing before 1949 and between 1949 and 1977 with the emphasis on mass-line policing. The second section, which is the core of the study, discusses several broad dimensions associated with the so-called strike-hard policing and community policing adopted by the Chinese police since 1978. These pivotal areas include policies and laws, organizational structure and development, field practices and effectiveness, and police accountability and reform. The last section discusses critical issues for the future development of Chinese policing and specifies directions for future research on Chinese policing.

One country, three populations: Trust in police among migrants, villagers, and urbanites in China

Ivan Y. Sun; Rong Hu; Daniel F.K. Wong; Xuesong He; Jessica C. M. Li

While the past decade has witnessed the burgeoning of research on public assessments of the police in China, marginalized social groups have rarely been considered in this line of inquiry. Using data collected from migrant workers, rural villagers, and urban dwellers, this study assesses whether Chinese perceptions of the police are distinguishable along procedural-based trust and outcome-based trust and whether expressive concerns and instrumental concerns are predictive of trust in the police. Findings show that Chinese citizens tend to conflate procedural-based trust and outcome-based trust. Expressive concerns play a more important role than instrumental concerns, with such expressive variables as trust in neighborhood residents committee, perceived law and order, and quality of life influencing trust in the police. Public perceptions of police trustworthiness are also significantly linked to media influence. Directions for future research are discussed.

Social capital, political participation, and trust in the police in urban China

Ivan Y. Sun; Rong Hu; Yuning Wu

Trust in the police has emerged as a critical issue in China where the police have experienced a crisis of legitimacy. Only a small number of studies, however, have empirically assessed Chinese citizens’ trust in the police. Moreover, the effects of citizens’ participation in social and political activity on evaluations of the police have rarely been investigated. Using survey data collected from over 3,500 Chinese citizens in eight cities, this study examines the impact of social capital and political participation on trust in the police, controlling for demographic characteristics, sense of safety, and locality. Trust in the leaders of neighborhood committees increased the likelihood of trust in the police. A sense of safety also raised the odds of trust in the police. Citizens’ trust in the police is also predicted by trust in neighbors, participation in political activity, and gender. Trust in the police varies across cities and is explained by some common and distinctive variables.

The Impact of 9/11 on Organizational Development Among State and Local Law Enforcement Agencies

Daniel E. Marks; Ivan Y. Sun

This study examines the impact of the 9/11 terrorist attacks on organizational development of American state and local law enforcement agencies. Content analyses of police discourse in two practitioner magazines spanning from 1999 to 2004 are used to determine specific organizational changes that have been triggered by 9/11. Findings from our analyses indicate that changes have occurred and continue to develop mainly in organizational structures and processes. Changes in internal structures, such as the creation of a counterterrorism unit, tend to occur only in larger metropolitan and state police agencies. Changes in organizational processes or operations tend to be far more universal and typically involve an increased collaboration among police departments, specifically greater openness toward information sharing. Implications for future research are discussed.

Trust in police: A comparison of China and Taiwan

Yuning Wu; Margarita Poteyeva; Ivan Y. Sun

Public trust has become a critical issue in transitional societies, such as China and Taiwan, where the legitimacy and accountability of the government in general, and legal authorities in particular, have been frequently scrutinized. Based on nationwide random samples, this study tests the explanatory power of three theories, the social structural thesis, the institutional performance thesis, and the cultural thesis, in accounting for public trust in police in China and Taiwan. Results show that Chinese citizens have higher levels of trust in police than do Taiwanese. The higher level of Chinese trust, to a large extent, derives from greater confidence in macroeconomic conditions and satisfaction with government responsiveness. The performance thesis, thus, receives the strongest support. Results also show some support for the cultural perspective that traditional values, such as interpersonal trust, promote trust in police in both societies. Policy implications are provided for enhancing police legitimacy and facilitating police reform in China and Taiwan.

Public trust in the police in Taiwan: a test of instrumental and expressive models

Ivan Y. Sun; Susyan Jou; Charles C Hou; Yao-chung (Lennon) Chang

Although public assessments of the police have become the focal concern of a substantial amount of research efforts since the 1970s, a very small number of studies have analysed public opinions on the Taiwan police. Using survey data collected from three cities and two counties in 2010, this study expands the existing literature by assessing whether Taiwan residents’ perceptions are distinguishable in terms of procedural-based trust and outcome-based trust and whether both the instrumental and expressive models are predictive of Taiwanese trust in the police. Findings revealed that the Taiwanese tended to conflate procedural-based and outcome-based trust. Both the instrumental model (concerns about safety) and the expressive model (trust in neighbours and perceived quality of life) were significantly linked to Taiwanese trust in the police. Satisfaction with government performance and media influence were also predictive of police trustworthiness. Directions for future research and policy are discussed.
