An explanation for camera perspective bias in voluntariness judgment for video-recorded confession: Suggestion of cognitive frame

Three experiments were conducted to test the hypothesis that difference in voluntariness judgment for a custodial confession filmed in different camera focuses ("camera perspective bias") could occur because a particular camera focus conveys a suggestion of a particular cognitive frame. In Experiment 1, 146 juror eligible adults in Korea showed a camera perspective bias in voluntariness judgment with a simulated confession filmed with two cameras of different focuses, one on the suspect and the other on the detective. In Experiment 2, the same bias in voluntariness judgment emerged without cameras when the participants were cognitively framed, prior to listening to the audio track of the videos used in Experiment 1, by instructions to make either a voluntariness judgment for a confession or a coerciveness judgment for an interrogation. In Experiment 3, the camera perspective bias in voluntariness judgment disappeared when the participants viewing the video focused on the suspect were initially framed to make coerciveness judgment for the interrogation and the participants viewing the video focused on the detective were initially framed to make voluntariness judgment for the confession. The results in combination indicated that a particular camera focus may convey a suggestion of a particular cognitive frame in which a video-recorded confession/interrogation is initially represented. Some forensic and policy implications were discussed.     

Application of 3D Laser Scanner to Forensic Engineering

In the case of building collapses and overturned structures, a three‐dimensional (3D) collapse or overturn model is required to reconstruct the accident. As construction sites become increasingly complex and large, 3D laser scanning is sometimes the best tool to accurately document and store the site conditions. This case report presents one case of a structure collapse and one case of an overturned crane reconstructed by a 3D laser scanner. In the case of structural collapse of a prefabricated shoring system, a 3D model reconstructed all the members successfully, a task that is nearly impossible using a scale such as a tape measure. The reconstructed prefabricated shoring system was verified through a structural analysis through comparison with the construction drawings to investigate faults in construction. In the case of the overturned crane, the jib angle and other major dimensions were successfully acquired through 3D laser scanning and used to estimate the working radius. As a result, the propriety of the working radius with the given lifting load was successfully determined.     

School Principals’ Perceptions of Crime Risk and Academic Climate: Links to School Safety Practices

ABSTRACT

Little is known about principals’ perceptions and their links to how school safety practices operate. Using data from School Survey on Crime and Safety from 2,009 public schools in the US, the current study examines the extent to which principals/administrators’ perceptions of academic climate and crime risk are related to school practices regarding safety and discipline. Results show that principals’ perceptions directly relate to school safety practices when controlling for school characteristics, and also explain how selected school characteristics relate to safety practices.Overall, the present study highlights the importance of principals’ perceptions of crime risk and academic climate in school safety practices. Policy implications and potential limitations of the study are discussed.     

The transition in the political economy of South Korean development

This article analyzes the current transition in the political economy of South Korea in the context of political democratization and economic development. Because South Korea can be regarded as a case in which successful economic growth preceded political democratization, the article reviews the advantage and the disadvantage of late industrialization and its limitations. It discusses rising conflicts of interest among economic agents, labor disputes, and the erosion of international competitiveness. The article also reviews the sociopolitical reform program advanced by the new administration and its ramifications for the economic prospects. The article concludes that the Korean economy will continue to grow but not as fast as it had grown in the past and that the new political environment will play a critical role in determining the characteristics of capitalism in South Korea. The success of future economic development will depend on the stability of the political system and the national capacity to resolve conflict of interests.
