Collection and especially analysis of open‐ended survey responses are relatively rare in the discipline and when conducted are almost exclusively done through human coding. We present an alternative, semiautomated approach, the structural topic model (STM) (Roberts, Stewart, and Airoldi 2013; Roberts et al. 2013), that draws on recent developments in machine learning based analysis of textual data. A crucial contribution of the method is that it incorporates information about the document, such as the author's gender, political affiliation, and treatment assignment (if an experimental study). This article focuses on how the STM is helpful for survey researchers and experimentalists. The STM makes analyzing open‐ended responses easier, more revealing, and capable of being used to estimate treatment effects. We illustrate these innovations with analysis of text from surveys and experiments.  相似文献

A skeleton discovered in Grand Forks, North Dakota was purported to belong to Clelland “Clell” Miller, a James‐Younger gang member, who was killed during the Northfield Bank robbery on September 7, 1876. A 3‐D image from a computer tomography (CT) scan of the skull was obtained, and a craniofacial superimposition was conducted to determine if the skull could belong to Miller. The superimposition method used in this case was to overlay the CT image of the skull onto Miller's postmortem photograph. In addition to the craniofacial superimposition, the images were juxtaposed to compare similarities or differences in facial morphology between the skull and photograph. Superimposition methods can be used to exclude identifications; however, they should not be used as a conclusive method for identification. In this case, there were sufficient similarities between the skull and Miller's photograph; therefore, the skull could not be eliminated as possibly being that of Miller.  相似文献

Overview and scrutiny committees were intended to provide a counterbalance to executive decision-making. This paper presents an 'audit' of local government scrutiny based upon research conducted over the last five years. Three key findings emerge from the review of evidence to date: the research findings are remarkably consistent over time and between authors; all research concludes that, in general, overview and scrutiny is still struggling; although a mixed picture emerges when examining progress on individual roles for scrutiny. Indeed, research indicates that scrutiny is - in some authorities - making a valuable contribution in terms of policy review but is still failing to hold the executive to account effectively. The relationship between scrutiny and performance management remains underdeveloped, whilst external scrutiny constitutes a marginal activity for most authorities. The paper concludes that such findings reflect the importance of local political and organisational factors which dictate the boundaries and shape of overview and scrutiny: representing a triumph of local context over government-prescribed structural and constitutional change.  相似文献

A study was conducted to determine whether prior research had accurately conceptualised community correctional officers' experience of role conflict on the basis of officers' role preferences. It was hypothesised that officers who were welfare workers or punitive officers would experience inter-role conflict while those who attempted to combine the welfare and punitive roles (protective agents) would experience intra-role conflict and role ambiguity. Furthermore, an exploration of how inter-role conflict, intra-role conflict, role ambiguity, and officers' role preferences were related to occupational burnout was conducted. It was found in this study that officers' preferences for the role of welfare worker, protective agent, or punitive officer were not related to the level of inter-role conflict, intra-role conflict, or role ambiguity experienced by officers. Officers' role preferences were not related to burnout. Inter-role conflict and intra-role conflict were associated with emotional exhaustion. These findings call into question the whole tradition in the community corrections literature of inferring role conflict from officers' role preferences and necessitate that the whole issue of whether officers experience role conflict be revisited by employing direct measures of role conflict.  相似文献

An American specialist on Russian politics and federalism examines the democratizing effects, intended and unintended, of President Vladimir Putin's federative reforms. Focus is on the "harmonization" of regional constitutions and legislation with federal laws and the RF Constitution in the name of the "reintegration of Russia's legal space." On the basis of detailed analysis of changes in regional constitutions and laws ensuing from the harmonization policy, the author assesses the impact of this aspect of the reforms on democratization in Russia's regions. Regional issues examined include the separation and balance of power between the executive and legislative branches, political and civil rights, the level of demand for democratic laws and independent judicial review, and the emergence of stakeholders of these reforms within civil society.  相似文献

Most scholars find presidents generally fail at moving the public's views on policy; however, although presidents may fail at opinion leadership at the aggregate level, examining specific communication tactics may yield a more nuanced view of when presidents succeed or fail at leadership. In this article, using a comprehensive data set spanning 1953 to 2001, several strategic communication tactics through which the president might influence temporary opinion movement are examined. Findings show that presidential use of nationally televised addresses is the most consistently effective strategy to enhance presidential leadership, but the effect is lessened for later serving presidents. Strategies involving domestic travel never positively affect leadership, while televised interactions with the media always negatively affect leadership success. The cumulative results imply that presidents can momentarily lead public opinion with particular tactics and that the conditions enhancing leadership are partially in their control, suggesting presidential capability to strategically lead public opinion.  相似文献

Objective

The late James Q. Wilson (1931-2012) was a prolific scholar and made many important contributions to the field of criminology. Less well known, however, is that Wilson was a great advocate of early prevention of delinquency and later offending. This essay examines this aspect of Wilson's overall contribution to criminology.

Materials and methods

Narrative review of Wilson's research and writings on early crime prevention and developmental criminology.

Results

Three key events delineate Wilson's long-lasting support for early crime prevention: his 1983 "Raising Kids" article with its special focus on family-based prevention; his help to initiate and champion developmental and longitudinal research on offending in the 1980s and 1990s; and his influential writings and behind-the-scenes work on early prevention throughout the 1990s and 2000s.

Conclusions

Wilson played an important role in advocating for early crime prevention. Without question, this is part of his enduring legacy to the field of criminology.  相似文献

Though a large body of research has found that peer social network characteristics influence both offending and victimization, relatively little is known about the influence of social network characteristics on adolescent sexual victimization. Attractiveness and sociability largely indicate popularity for teenage females, which in turn leads to earlier onset of dating, greater dating options, and potential risk of sexual victimization—an observation not tested in the criminological and criminal justice literature. We suggest and evaluate 2 competing hypotheses: that popularity within a network insulates females from sexual victimization and that popularity may increase exposure to delinquent others and facilitate sexual victimization. Results suggest that popularity does not have a consistent effect but instead that its role is conditioned by the deviance of the network. Popularity is associated with an increase in the likelihood of victimization when peer deviance is high but with a decrease when peer deviance is low. We further demonstrate that an interaction between a female's own drinking and the proportion of her friends that are male strongly affects her likelihood of sexual victimization. Implications for policy and future research are explored.  相似文献
