Measuring the crime displacement and diffusion of benefit effects of open-street CCTV in South Korea

Crime prevention strategies are implemented to reduce the damage caused by crimes with CCTV (Closed-Circuit Television) being broadly accepted as one of the main strategies. However, along with CCTV's perceived high expectations as crime deterrent, there is also a growing controversy over CCTV's potentially unexpected limitations. For example, the crime displacement (the presence of CCTV will change the locations of crime and its total number will not change) and the diffusion effects of crime control benefits (the crime prevention effect of CCTV may filter through to neighboring areas) are the representative controversial issues. In this study, we aimed to verify the crime displacement and the diffusion of benefit of open-street CCTV by analyzing the crime tendencies empirically.Gwang Myeong City in Gyeonggi Province, South Korea was chosen to analyze the crime displacement using the WDQ (Weighted Displacement Quotient) which compares the crime tendency of a location with that of its neighboring areas. The results showed that the crime prevention effect of the CCTV was significant. The number of robberies and thefts in the areas with CCTV installed reduced by 47.4%, while the areas without CCTV showed practically no change in the number of crimes. The crime displacement caused by the CCTV was not either found or inconsequential, and the crime rates in the neighboring areas also decreased slightly. Of major cause for concern was the fact that CCTV was marginally effective in deterring violence and as such, there should be a more detailed scientific analysis of the pattern and type of crimes committed in an area where CCTV's are being installed.     

Effect of Sex Offenders Treatment Program on Cognitive and Emotional Characteristics of Mentally Ill Sex Offenders

This study assessed the effect of a 10‐week cognitive behavior treatment program in 30 mentally ill sex offenders. The effect of the program was evaluated using the Interpersonal Responsiveness Index (IRI), UCLA Loneliness Scale (UCLALS), Coping Using Sex Inventory (CUSI), and Rape Myth Acceptance Scale (RMAS). Data were analyzed using the paired t‐test. The ability of sex offenders to cope with sexual acts when they faced stressful situations and to accept the rape myth was significantly improved on CUSI (t = 2.09, p = 0.04) and RMAS (t = 5.45, p < 0.001). Feelings of isolation and the ability to empathize based on IRI (t = 0.62, p = 0.54) and UCLALS (t = 0.88, p = 0.38) were not significantly improved. To prevent recidivism, treatment for mentally ill sex offenders should focus on changes in their cognitive and emotional characteristics in addition to their main psychiatric illness.     

Downsizing Hegemony: Alliance,Domestic Politics,and American Retrenchment in East Asia, 1969–2017

By investigating the domestic debate over the US troop reduction in Japan and South Korea for the past several decades, this article explores variation in the Asian allies’ reactions to American retrenchment. Instead of inferring regional responses solely from external security environments, this paper pays particular attention to domestic political contexts in which different political actors compete to frame the meanings and consequences of the US military presence, with implications for alliance dynamics in East Asia. I argue that along with the perceived levels of external threats, considerations of foreign policy autonomy and political legitimacy shape the ways in which the two Asian allies have responded to the US retrenchment.     

Frontline worker compliance with transparency reforms: Barriers posed by family and financial responsibilities

Significant development funding flows to informational interventions intended to improve public services. Such “transparency fixes” often depend on the cooperation of frontline workers who produce or disseminate information for citizens. This article examines frontline worker compliance with a transparency intervention in Bangalore's water sector. Why did compliance vary across neighborhoods, and why did workers exhibit modest rates of compliance overall? Drawing on ethnographic observation and an original data set, this article finds that variation in workers' family responsibilities and financial circumstances largely explains variation in compliance with the intervention. Furthermore, workers often prioritize long‐standing responsibilities over new tasks seen as add‐ons, leading to modest rates of compliance overall. Perceptions of “core” jobs can be sticky—especially when reaffirmed through interactions with citizens. This article represents one of the first multimethod companions to a field experiment, and illustrates how the analysis of qualitative and observational data can contribute to impact evaluation.     

Alterations of Length Heteroplasmy in Mitochondrial DNA Under Various Amplification Conditions*

Abstract: There are several areas within mitochondrial DNA that show length heteroplasmy. If the heteroplasmy pattern is unique and consistent for each person, it may be used to support an interpretation of exclusion in identity testing. We investigated whether the length heteroplasmy pattern would be consistent under different amplification conditions. We also determined whether various amplification parameters would affect the homopolymeric cytosine stretches (C‐stretch) in HV1. Monoclonal samples tended to be heteroplasmic after amplification. After several repetitions, C‐stretch patterns of all samples were inconsistent even under the same amplification conditions. Increased PCR cycles and high template concentrations resulted in a more frequent heteroplasmic tendency. These amplification parameters seem to have little effect if samples are not long enough in C‐stretch or total length of the segment from nt 16180 to nt 16193. It is suggested that the pattern of length heteroplasmy cannot be used as an additional polymorphic marker.     

Coup,riot, war: How political institutions and ethnic politics shape alternative forms of political violence

This article explores how different types of governance systems shape different forms of political violence. We identify four governance types by combining the “institutional” dimension of coalition size represented by a minimum winning coalition (MWC) and the “ethno-political” dimension represented by the size of ethnic groups participating in the governing coalition. This study hypothesizes that (a) an exclusive system (small MWC; narrow-based ethnic coalition) is likely to engender civil war, (b) an oversized system (small MWC; broad-based ethnic coalition) is likely to generate a coup, and (c) an undersized system (large MWC; narrow-based ethnic coalition) is likely to stimulate riots or protests. Statistical analyses confirm all three hypotheses, implying that opposition groups choose alternative forms of conflict that maximize their chances of accessing power under different governance configurations. The article concludes by identifying three possible paths toward inclusive governance and suggesting that institutional reform before ethnic inclusion makes a transition toward inclusive governance far less dangerous.

Changing patterns of social network structure in composer-singer relationships: A case study of the Korean popular music industry, 1927–1997

This study focuses on relationships between two different sets of actors in the Korean popular music industry—songwriters and singers—who were mutually connected in the production of hit songs during the period of 1927–1997. Data for the present study were obtained from a set of publications providing the following information about hit songs in Korea since 1925: title, musical style, year of recording and release, lyricist(s), composer(s), singer(s), and the label company producing the record or album. Data are used to test a series of hypotheses on the nature of relationships between songwriters and singers. Results of the present analysis show that composer-singer pairs are likely to have produced only one hit song together, due to a high degree of market competition in the popular music industry. Because composers tend to have more control over their relationships with singers than singers have in their relationships with composers, composers are more likely to have multiple hit songs with more than one singer than are singers to have multiple hit songs with more than one composer. Genres of popular music in Korea have changed significantly since 1950, and these changes have also affected composer-singer relations. The diversification of genres has reduced the concentration of hit songs by selected elite composer-singer pairs over time. Another important consequence of the changes in genres is that the proportion of hit songs by artists playing dual roles as composer and singer has dramatically increased in recent years.     

The Twin Peaks of Pyongyang

The United States has been negotiating with North Korea in an effort to have it renounce its nuclear program for over a decade, since Washington negotiated an Agreed Framework in 1994. In this time, North Korea has only amassed more plutonium. The negotiations are hindered by mutual distrust and hostility, but it is doubtful whether any change in Washington's attitude toward the dprk would help solve the nuclear issue. It is the Kim regime that is the core problem. Until the regime is removed, there can be no durable peace in the region. This article suggests that with the prospect for a negotiated resolution of the nuclear issue remote, and since any attempt to remove the Kim regime militarily would entail huge costs, Washington might consider a third option: directly engaging the North Korean people.     

Development of Latent Fingermarks on Surfaces of Food‐A More Realistic Approach

Latent fingermark developing methods from food (mandarin, egg, banana, apple, potato, carrot, eggplant, onion, bell pepper, and tomato) surface has been studied by 10 methods, including powdering method, small particle reagent method, and cyanoacrylate fuming method. The foods were stored under two conditions (room temperature and refrigerator) before fingermark deposition and aged for 2, 24, 48, and 72 h before fingermark development. In most of the food surfaces used in this study, cyanoacrylate fuming with 80% relative humidity was superior to the powder or small particle reagent methods. The quality of the fingermarks varied depending on the storage conditions before the fingermark deposition (in the refrigerator or at ambient temperature) and the time elapsed since the fingermark deposition. However, the storage conditions before the fingermark deposition and the time elapsed since the fingermark deposition did not show any correlation with the quality of the fingermark.
