调查报告:农村商人之法律意识

全面地了解农村商人之法律意识现状对于建设社会主义新农村具有极其重要的现实价值和重要意义。调查发现:18周岁至40周岁之间、文化程度较低的人构成了农村商人的主力军;农村商人法律意识感性层面还很不成熟,客观上表现为感知途径的狭窄等,主观上,因文化程度等因素导致认知能力较低;农村商人法律意识理性层面存在缺位问题,一方面,传统信仰相对于法律信仰占据优势地位,另一方面,法的适用过程中存在的问题严重影响了农村商人之法律信仰的养成;普法宣传一方面过多的流于形式,另一方面普法宣传方式还有待改进。     

Area characteristics and regional variates as determinants of area property crime levels

This article seeks to examine the area characteristics that act as determinants of area property crime levels, namely, incidence and prevalence. The crime figures are extracted from the 1984 British Crime Survey. Area characteristics are taken from the 1981 UK census. Initial exploratory analysis considers the non-Gaussian nature of the crime data, the statistical implications of this, and the transformations used to overcome these problems. In addition, possible regional and inner-city/non-inner-city variations are considered. The later stages move from simple individual correlations to multiple regression models. Three regression models are considered and the reasons for refining these are explored, with the results indicating that both area characteristics and regional influences play a role as determinants of the area crime level. In particular, population density and the area population age profile have significant roles to play. The conclusions support the recent revival of the application of ecological concepts in the analysis of crime levels.     

Does survey mode matter for studying electoral behaviour? Evidence from the 2009 German Longitudinal Election Study

Online surveys are becoming increasingly popular in the social sciences, particularly in electoral research. However, several studies have shown that participants who take part in online surveys differ significantly from those in other surveys. Still, since electoral research aims primarily at explaining voting behaviour (i.e., looks at slopes and intercepts in statistical model output), online surveys are deemed to be useful tools if models based on this data source arrive at similar conclusions than models based e.g. on random-sample face-to-face or telephone surveys. This paper analyses these relationships by comparing models of voting behaviour based on data from various survey modes with different sample selections conducted by the German Longitudinal Election Study (GLES) 2009. The results indicate that the data quality of the different survey types is comparable; online surveys are thus useful for electoral research.     

A Quasi-Experimental Analysis of Schoolwide Violence Prevention Programs

Violence prevention programs are commonplace in today’s schools, though reviews of the literature reveal mixed empirical findings on their effectiveness. Often, these programs include a variety of components such as social skills training, student mentoring, and activities designed to build a sense of school community that have not been tested for individual effectiveness. To fill this gap, we wanted to determine the relationships between specific violence prevention program components and aggression and violence outcomes. Using the U.S. Department of Education’s School Survey on Crime and Safety, we estimated the effects of components of violence prevention programs through analyses with proportional odds logistic regression and Poisson regression models. We found significant relationships between three violence prevention program components (individual attention, mentoring, tutoring, and/or coaching; recreational, enrichment, or leisure activities; and involving students in resolving student conduct problems) and aggression and violence outcomes.

Women in a changing economy: the misleading tale of participation rates in a historical perspective

In this article I focus on women's advancement in the Swedish labour market during more than a century. By applying a long-term perspective I give the historical background to what is commonly seen as a success story. By reassessing census and labour force survey data I show that participation rates may tell a misleading tale not only for the past but also for the present. In a long-term perspective, Sweden does not stand out as a country with high female labour force participation rates. It was not until the mid-1960s that market work came to play a larger part of women's life, since young women worked until they had children and older married women returned to the labour force after having raised a family. During the late 1960s and the 1970s, women with children under the age of seven became an integrated part of the labour force. It seemed as if welfare reforms supported women's market work in an unprecedented way; gender differences in labour force participation decreased and became very small. A reassessment of labour force participation rates together with alternative measures of market work such as at-work and market-hours rates show that similarly to how they underestimate women's market work and contributions to production during the early decades of the twentieth century, they overestimate women's market work at the end of the century, neglecting the extent to which reproductive responsibilities still interfere with women's paid work through absence and part-time work.     

Do politicians anticipate voter control? A comparative study of representatives’ accountability beliefs

Representation literature is rife with the assumption that politicians are responsive to voter preferences because their re-election is contingent upon the approval of those voters, approval that can be won by furthering their desires or, similarly, that can be threatened by ignoring their wishes. Hence, scholars argue that the anticipation of electoral accountability by politicians constitutes a crucial guarantor of (policy) responsiveness; as long as politicians believe that voters are aware of what they do and will take it into account on election day, they are expected to work hard at keeping these voters satisfied. If, on the other hand, politicians were to think what they say and do is inconsequential for citizens’ voting behaviour, they may see leeway to ignore their preferences. In this study, we therefore examine whether politicians anticipate electoral accountability in the first place. In particular, we ask 782 Members of Parliament in Belgium, Germany, Canada and Switzerland in a face-to-face survey about the anticipation of voter control; whether they believe that voters are aware of their behaviour in parliament and their personal policy positions, are able to evaluate the outcomes of their political work, and, finally, whether this knowledge affects their vote choice. We find that a sizable number of MPs believe that voters are aware of what they do and say and take that into account at the ballot box. Still, this general image of rather strong anticipation of voter control hides considerable variation; politicians in party-centred systems (in Belgium and some politicians in Germany that are elected on closed party lists), anticipate less voter control compared to politicians in more candidate-centred systems (Canada and Switzerland). Within these countries, we find that populist politicians are more convinced that voters know about their political actions and take this knowledge into account in elections; it seems that politicians who take pride in being close to voters (and their preferences), also feel more monitored by these voters. Finally, we show that politicians’ views of voter control do not reflect the likelihood that they might be held to account; politicians whose behaviour is more visible and whose policy profile should therefore be better known to voters do not feel the weight of voter control more strongly.     

Single Outcome Agreements and Partnership Working in Scottish Local Government – Year One

Single Outcome Agreements (SOAs) are a mechanism that it is argued will deliver key national and local priorities based on a new relationship between central and local government in Scotland. SOAs are to be developed and implemented through partnership working exercised by Community Planning Partnerships (CPPs). A survey of the first (2008) SOA participants from local authorities and their Community Planning partners was conducted in 2008, with a particular focus on the interrelationships between the 2008 SOA development process and partnership working at the local level. Findings of this study suggest that there was a positive link between the strength of existing CPPs and partner engagement in the 2008 SOA development. However, partner engagement in the 2008 SOA development process did not affect survey respondents' confidence that the ongoing SOA development and implementation will strengthen partnership working in the long -term. This study also suggests that in addition to the practical difficulties such as limited time and staff resources, mistrust between local partners, and local players' scepticism about the central government's intention to free up local government may be barriers to the success of the SOA. Overall, respondents in this study showed realistic but hopeful attitudes to what the SOA was about and what could be achieved through it over time. The information gathered through this study should be merited as baseline data which captured the SOA participants' early experience and expectations.     

An Assessment of Journal Quality in Public Administration

Using results from a survey of editors and board members from 39 public administration journals as well the impact factor scores created by ISI Thompson this research develops an integrated assessment of journal quality using both objective and subjective measurement tools. The findings suggest that relying on one ranking approach misses out on several important issues regarding journal quality. In addition, when evaluating outlets for publishing in public administration, there often exists a bias against journals not published in the United States. Finally, the highest-ranked generalist journals are also publishing work that is also applicable to scholars working in various subfields.
