'Out Of Sight, Out Of Mind': Assessing The Impact Of Markets For Children's Residential Care

This article is concerned with assessing the effectiveness of markets for complex professional services in social care. The issue is explored through an account of developments in the children's residential care sector. Over the past five years there has been a steady expansion in the role of external markets in this area. However, this was not required by the Children Act 1989 and has become the subject of considerable debate between policy makers and practitioners. While some favour an extension of choice, others argue that a further decline in local authority run provision will be both costly and detrimental in terms of meeting key policy goals. In order to assess these claims, reference is made to the findings of a study of purchasing practices for children's residential care in twelve local authorities in England and Wales. The impact of the emerging market is analysed along two dimensions. Firstly, we assess how far it is operating efficiently, concentrating on market structure, information and transaction costs. Secondly, attention is given to the impact of market changes on the policy objectives of: localized placements; ensuring adequate safeguards; and matching needs and services. The results reveal that there have been significant costs associated with markets in children's services. In a context of government efforts to promote modes of service delivery on the basis of 'what works', these difficulties have certain implications. Not only do they draw attention to the need for greater collaboration between purchasers and providers, they also point to the continued relevance and usefulness of local authority managed provision.     

Artenschutz und Straßenplanung – Neues aus Leipzig

Zusammenfassung  In seinem Urteil zur Nordumgehung Bad Oeynhausen hat sich das Bundesverwaltungsgericht um eine Sch?rfung des Profils der im Rahmen der Fachplanung beachtlichen Anforderungen des besonderen Artenschutzrechts bemüht. Der Beitrag behandelt einige Kernaussagen der Entscheidung und widmet sich der Frage, ob der Praxis damit eine hinreiche Grundlage zur rechtssicheren Bew?ltigung artenschutzrechtlicher Konfliktlagen verfügbar ist.     

Infrared Imaging of the Crime Scene: Possibilities and Pitfalls

All objects radiate infrared energy invisible to the human eye, which can be imaged by infrared cameras, visualizing differences in temperature and/or emissivity of objects. Infrared imaging is an emerging technique for forensic investigators. The rapid, nondestructive, and noncontact features of infrared imaging indicate its suitability for many forensic applications, ranging from the estimation of time of death to the detection of blood stains on dark backgrounds. This paper provides an overview of the principles and instrumentation involved in infrared imaging. Difficulties concerning the image interpretation due to different radiation sources and different emissivity values within a scene are addressed. Finally, reported forensic applications are reviewed and supported by practical illustrations. When introduced in forensic casework, infrared imaging can help investigators to detect, to visualize, and to identify useful evidence nondestructively.     

Keeping promises: A systematic review and a new classification of gang control strategies

Purpose

We argue that inadequate frameworks to compare similar gang control strategies, and the scarcity of well-designed evaluations have hindered our ability to determine the effectiveness of existing programs. This article proposes a new typology of gang control strategies to use with logic models as tools to improve gang program evaluation.

Methods

We conducted a systematic review of gang control strategy evaluation reports and created a typology from the studies identified. Studies were selected on the basis of methodological quality in order to reflect only rigorous evaluations with credible research findings.

Results

Forty-five studies were selected and reviewed. Studies were classified in homogeneous categories based on the targeted population and the objective of the strategy. We infer logic models that consider the activities, outputs, and outcomes of each type of strategy.

Conclusion

A better framework for the comparison of similar studies may allow meta-analyses to be conducted, thereby improving our knowledge of what works. Logic models can move the field forward by allowing researchers to understand why some programs work and others do not. The improvement, both in quality and quantity, of program evaluation in gang research is crucial in order to move beyond claims of promising approaches.     

Unemployment,business cycles,crime, and the Canadian provinces

Purpose

Test the Cantor and Land (1985) model using multiple measures of the state of the economy.

Methods

A panel data set of the 10 Canadian provinces, 1981 – 2009, is analyzed using a hybrid modeling approach called a decomposition model. Rather than one economy-related model, four are included in the analysis: gross provincial product, gross provincial product per capita, unemployment rate, and low income.

Results

All economy-related variables matter for property and violent crime, but the sign and magnitude of the estimated parameters vary based on context.

Conclusions

The relationship between the economy and crime is complex. Only including one economy-related variable appears to result in omitted variable bias. As such, any evaluation of the relationship between the economy and crime must consider multiple measures of the economy.
