Planning Ahead? An Exploratory Study of South Korean Investigators’ Beliefs About Their Planning for Investigative Interviews of Suspects

Preparation and planning has been argued to be vitally important as to how effectively investigators undertake their interviews with suspects. Yet, it has also been found in previous research that investigators admit that they plan only occasionally, often attributing insufficient time as a reason for not undertaking the task. Employing a novel research paradigm that utilised theoretical foundations concerning planning, the present study explored empirically 95 South Korean financial crime investigators’ views, using a self-administered questionnaire. With the use of second-generation statistical modelling, an understanding was developed of the relative relationships between various concepts (which had themselves emerged from an established theoretical framework of planning that had been further extended to accommodate the context of the present study). The study found that perceived time pressures actually showed a very low association with interview planning. Rather, investigators’ self-belief as to their own capability alongside workplace culture was each found to have stronger associations with investigators’ intentions to plan for their interviews. As such, we argue that there should be more focus on improving occupational culture relating to interview planning, while developing training programs that identify, evaluate, and enhance investigators’ planning skills. Implications for practice are therefore discussed.     

Examining the Relationship Between the Structural Characteristics of Place and Crime by Imputing Census Block Data in Street Segments: Is the Pain Worth the Gain?

Objective

The current study proposes unique methods for apportioning existing census data in blocks to street segments and examines the effects of structural characteristics of street segments on crime. Also, this study tests if the effects of structural characteristics of street segments are similar with or distinct from those of blocks.

Methods

This study compiled a unique dataset in which block-level structural characteristics are apportioned to street segments utilizing the 2010 U.S. Census data of the cities of Anaheim, Santa Ana, and Huntington Beach in Orange County, California. Negative binomial regression models predicting crime that include measures of social disorganization and criminal opportunities in street segments and blocks were estimated.

Results

The results show that whereas some of the coefficients tested at the street segment level are similar to those aggregated to blocks, a few were quite different (most notably, racial/ethnic heterogeneity). Additional analyses confirm that the imputation methods are generally valid compared to data actually collected at the street segment level.

Conclusions

The results from the street segment models suggest that the structural characteristics from social disorganization and criminal opportunities theories at street segments may operate as crucial settings for crime. Also the results indicate that structural characteristics have generally similar effects on crime in street segments and blocks, yet have some distinct effects at the street segment level that may not be observable when looking at the block level. Such differences underscore the necessity of serious consideration of the issues of level of aggregation and unit of analysis when examining the structural characteristics-crime nexus.

     

A comparison of curfew and noncurfew violators using a self-report delinquency survey

The present study examines one city’s experience with a juvenile curfew ordinance. It compares characteristics of youths detained by the police for curfew violation with teenagers who did not have such police contact. Selfreport data reveal curfew violators admit committing more minor and serious delinquency, as well as status offenses, than noncurfew violators. Curfew violators also disclose higher victimization levels. Implications deriving from these observations are discussed.     

Thyroid Cartilage Ossification and Multislice Computed Tomography Examination: A Useful Tool for Age Assessment?

Abstract: Many authors have studied the thyroid cartilage ossification process using radiographic features for age estimation of individuals. Their results were various: Sugiyama reported excellent correlation coefficients between ossification rates and civil age, unlike most other authors. We hypothesized that recent advances in imaging techniques would enable more precise evaluation of the ossification of the thyroid cartilage. We retrospectively analyzed the CT scans of 312 French patients using postprocessing software to examine the pattern of thyroid cartilage ossification, calculating the ossified volume of the cartilage on 3D reconstructions. Pearson’s correlation coefficients for volume were 0.73 for men and 0.75 for women (standard error 18.02 and 17.06), indicating considerable inter‐individual variability. Although a correlation between civil age and morphological changes was found, these methods based on thyroid cartilage ossification were not accurate enough for the assessment of individual age.
