The purpose of this paper is to use an evaluation of a micro-place-based hot-spot policing implementation to highlight the potential issues raised by data quality standards in the recording and measurement of crime data and police officer movements.

The study focusses on an area of London (UK) which used a predictive algorithm to designate micro-place patrol zones for each police shift over a two-month period. Police officer movements are measured using GPS data from officer-worn radios. Descriptive statistics regarding the crime data commonly used to evaluate this type of implementation are presented, and simple analyses are presented to examine the effects of officer patrol duration (dosage) on crime in micro-place hot-spots.

The results suggest that patrols of 10-20 minutes in a given police shift have a significant impact on reducing crime; however, patrols of less than about 10 minutes and more than about 20 minutes are ineffective at deterring crime.

Due to the sparseness of officer GPS data, their paths have to be interpolated which could introduce error to the estimated patrol dosages. Similarly, errors and uncertainty in recorded crime data could have substantial impact on the designation of micro-place interventions and evaluations of their effectiveness.

This study is one of the first to use officer GPS data to estimate patrol dosage and places particular emphasis on the issue of data quality when evaluating micro-place interventions.

The purpose of this paper is to present a research method which offers insights into the factors which affect the optimal use and implementation of telecare, or which may lead to its rejection by older people with support needs – factors pertinent to those involved in the design and delivery of both telecare research studies and of services.

The methodology outlined, influenced by Chicago School and Science and Technology Studies, emphasises the importance of context when examining social phenomena, such as the use of technology. The multi-method approach identified key patterns which provide insights into how telecare was used by a sample of older adults, including information on its suboptimal use and rejection.

The study of telecare use in real-life situations – and the investigation of other complex social interventions – requires an approach which fully considers the importance of context in explaining social phenomena. The main value of the method and findings lies in the insights offered to designers of larger studies which seek to generalise results, including telecare randomised control trials, as well as for those involved in the delivery of telecare services to achieve optimal adoption and use.

The study methods described combined ethnographic, longitudinal and qualitative methodologies and creative research tools in an innovative way to allow exploration of how context affects the uptake and use of telecare.

It is unclear whether information obtained from a one parent can be used to infer the other parent's history of psychopathology. Two hundred and one parental dyads were asked to complete psychiatric interviews. Based on maternal report, non-participating husbands/ fathers had higher rates than participating fathers of psychiatric illness. For fathers who did participate, maternal report did not match direct interview of paternal psychopathology with sensitivities less than 0.40 and positive predictive values of 0.33 to 0.74. Psychopa -thology may be over-represented among fathers who do not participate in research. Mother report of paternal symptoms is not an effective proxy. Alternative methods need to be developed to: i) improve father participation or ii) identify psychiatric status in fathers who do not participate in research projects.
