Disclosure of income, assets and conflicts of interest can serve as powerful public accountability tools to draw attention to the abuse of public office, help prosecute corrupt offenders and create a culture of scrutiny in the public sector that deters corruption. Based on data of the World Bank’s Public Accountability Mechanisms initiative, we present the first indicator that captures a country’s financial disclosure in-law effort. By employing different panel data model specifications, we use this indicator to measure how the introduction of comprehensive financial disclosure systems impacted national corruption levels for 91 countries between 1996 and 2012. We present robust results that provide tentative evidence for a positive and significant relationship between a country’s capacity to control for corruption and the expansion of financial disclosure legislation for the years following the enactment.  相似文献

Objectives

This study examines the effectiveness of foot patrol in violent micro-places. A large urban police department deployed foot patrol in micro-places (hot spots) for a period of 90 days for two shifts each day. Our objective is to determine whether this activity impacted violent crime in these hot spots and whether spatial displacement of crime occurred.

Methods

Eight eligible foot beat locations were set by examining crime rates for previous years in order to identify micro-places of high criminal activity. We employed a quasi-experimental design comparing the four treatment to the four control areas, estimating panel-specific autoregressive models for 30 weeks prior to and 40 weeks after the treatment.

Results

Time series models revealed statistically significant reductions in violent crime in the micro-places receiving foot patrol treatment, while no such reductions were observed in the control areas. The deterrent effect, however, was short and dissipated quickly. Control areas did not experience any crime prevention benefit during this time period. No evidence of crime displacement to spatially contiguous areas was detected.

Conclusions

This contributes to the growing body of knowledge that focused police strategies within hot spots impact violent crime. Specifically, the implementation of foot patrol in high crime hot spots led to measurable reductions in aggravated assaults and robberies, without displacing crime to contiguous areas.

Objectives

To describe how social scientists, criminal justice practitioners, and administrative agencies collected administrative data to follow-up a criminological experiment after two decades. To make recommendations that will guide similar long-term follow-ups.

Methods

A case study approach describes the processes of and sociological benefits to collecting administrative data to assess criminal justice and life-course outcomes.

Results

While maintaining experimental integrity, we developed, executed, and verified processes to retrieve arrest, mortality, and residential data for the experimental subjects, which enabled us to complete the longest ever follow-up of a criminal justice experiment.

Conclusions

When experiments have policy implications, administrative data may be preferable to survey data for assessing primary effects. Successful social science research can be conducted in conjunction with multiple administrative agencies.

Drawing on a large-scale study examining the British broadsheets’ coverage of the first Gaza war, this paper proposes some methodological considerations for analyzing the particularly emotive discourse on the Palestinian-Israeli conflict, and suggests a reflective multi-methodological approach to account for both the complexities and the intensities of the conflict. The paper starts by arguing that, working with a large data-set, quantitative data are both required and required to be interpreted by acts of contextualisation. Two strategies of contextualization are then introduced: interpreting patterns and associations in the numerical data. Following this, the paper continues by examining the findings and dilemmas that have emerged from quantitative analysis, using qualitative analysis of editorial extracts. It therefore shows examples for how quantitative codes can be built into and built up by narratives and arguments. Doing this, it also demonstrates possible ways of connecting qualitative to quantitative research: explanation, extension, and transformation/subversion.  相似文献

This article challenges the current orthodoxy, for instance put forward by Driver and Martell (1998), that New Labour represents a clearly defined break from the Labour Party's past. Drawing upon accounts of Labour's historical development, I argue that Labour in government has always been concerned with forging cross-class alliances, more often than not in the face of bitter internal opposition from the party's grass-roots membership. I conclude that the objectives of the Blair government are not dissimilar from those of the Attlee and Wilson administrations, and that where the means to achieve these ends differ – for example with regard to social policy – this is a rational response to the profound economic and social changes that have taken place since the 1970s.  相似文献
