The relation between residential property and its surroundings and day- and night-time residential burglary

This article examines how residential property and its surroundings influence day- and night-time residential burglary. Crime Prevention Through Environmental Design (CPTED) principles of territoriality, surveillance, access control, target hardening, image maintenance, and activity support underpin the study. Data were collected by observing 851 houses in the city of Enschede, half of which were burgled and half representing a random selection of houses not burgled. Multilevel multinomial regression models were estimated for predicting day- and night-time burglaries. The findings show that territoriality and access control predict daytime burglary while access control and target hardening predict night-time burglary. The analysis controls for offender availability, target attractiveness, and residential stability. The conclusion is that two separate burglary prevention frameworks are needed: one for day-and another one for night-time burglary.

Reaching Hard-to-Survey Populations: Mode Choice and Mode Preference

Abstract This study assesses the effect of response-mode choices on response rates, and responsemode preferences of hard-to-survey populations: young adults, full-time workers, big city inhabitants, and non-Western immigrants. Using address-based sampling, a stratified sample of 3,496 households was selected. The first group of sample members was contacted face to face and could choose between a CAPI and web response mode. The second group, contacted by telephone, could choose between CATI and web. The third group, contacted by telephone, was randomly allocated to a response mode. Our address-based sampling technique was successful in reaching most of the hard-to-survey groups. Insufficient numbers of non- Western immigrants were reached; therefore this group was excluded from our analyses. In our mixed-effect models, no significant effects on the willingness to participate were found for mode choice. We found that full-time workers and young adults were significantly more likely to choose web over CAPI when contacted face to face.

Analysis of Quality of Proxy Questions in Health Surveys by Behavior Coding

The aim of this study is to show how to analyze the quality of questions for proxy informants by means of behavior coding. Proxy questions can undermine survey data quality because of the fact that proxies respond to questions on behalf of other people. Behavior coding can improve questions by analyzing interviewer–respondent interactions. Twenty-nine proxies participated in the pretesting of a disability questionnaire. The questionnaire includes 11 questions related to daily-life limitations as a result of health problems. Interviewer–proxy interactions were coded and analyzed by means of Sequence Viewer program. The percentages, from a methodological perspective, of ideal “question-and-answer” sequences varied from 28% to 76% throughout the 11 questions analyzed. The results obtained pointed out the necessity of reviewing some of the proxy questions analyzed. Behavior coding can improve the quality of proxy questions in health surveys when proxy informants are surveyed.
