C335. Some numerology for the mass ratio of proton to electron,and a partially Bayesian evaluation

Recent small sample studies of estimators for the shape parameter a of the negative binomial distribution (NBD) tend to indicate that the choice of estimator can be reduced to a choice between the method of moments estimator, maximum likelihood estimator (MLE), maximum quasi-likelihood estimator and the conditional likelihood estimator (CLE). In this paper the results of a comprehensive simulation study are reported to assist with the choice from these four estimators. The study includes a traditional procedure for assessing estimators for the shape parameter of the NBD and in addition introduces an alternative assessment procedure. Based on the traditional approach the CLE is considered to perform the best overall for the range of parameter values and sample sizes considered. The alternative assessment procedure indicates that the MLE is the preferred estimator.     

A fistful of euros: Is the German one‐euro job workfare scheme effective for participants?

Hohmeyer K, Wolff J. A fistful of euros: is the German one‐euro job workfare scheme effective for participants? Welfare reforms have constituted a major policy issue in many OECD countries in recent decades. In Germany, a major reform in 2005 emphasised the activation of welfare recipients and introduced a workfare programme –‘One‐Euro Jobs’– on a large scale. In the present study, the impact of one‐euro jobs on the employment prospects of different groups of participants was estimated. The analysis was conducted on a large sample of welfare recipients using propensity score matching. The sample of one‐euro job participants and other welfare recipients was drawn from administrative records comprising all those who started their participation in the programme in early 2005. Our results showed that participation slightly improved the medium‐term employment prospects for women but not for men. Participation reduced the employment rate of participants younger than 25 years but raised it for some of the older participant groups. In conclusion, one‐euro jobs are effective for participants who have been jobless for several years but ineffective for participants who were recently employed.     

完善中国高校内部教学评估机制的对策

完善高校教学评估机制,促进教学质量保障体系建设对于高校提高教学质量、深化教学改革、促进自主发展有着十分重要的意义。当前中国高校内部教学评估机制存在价值取向不当、评估主体单一、评估制度设计不科学、制度实施缺乏有效保障等突出问题。新形势下,高校应当积极借鉴国际经验,在明确学校办学目标和使命的基础上,以深化教学改革、加强内涵建设、提高教学质量、促进自主发展为目标,从评估规划、评估执行、评估控制、反馈处理等角度构建多位一体的教学评估机制,促进学校教学质量保障体系的建设。     

城市品牌研究的知识图谱分析

运用知识图谱这种可视化的文献分析工具,对城市品牌研究文献进行分析。研究表明:(1)2007~2011年,城市品牌研究文献数量迅速增加,城市品牌研究开始成为热点。(2)从关键词共现分析看,城市品牌研究主要建立在讨论城市品牌建构路径和城市品牌建设具体方法上。(3)从文献共被引关系看,城市品牌研究可以分为品牌本身的讨论、宜居城市的生活环境以及市民的身体健康与城市品牌的关系、城市品牌与城市营销之间的关系三个阶段。进而指出,城市品牌研究的重点方向应该是对城市品牌的影响因素及形成过程、城市品牌评价系统的研究。     

Bilateral Donors' Efforts to Assess and Manage UN Agencies' Effectiveness: Seeking a Balance between Paris Principles and Domestic Accountability

Since the turn of the century, results orientation and performance measurement have become buzzwords in development aid. Bilateral donors are increasingly concerned about the effectiveness of core‐funded UN specialised agencies, funds and programmes, through which they channel a substantial part of their funds. While the logic for increased monitoring is clear, it is less evident how to assess this information for purposes of accountability, performance‐based funding and governance. This article describes the general evolution in this area and discusses two major initiatives to harmonise and align bilateral assessments, using case‐study material from three bilateral donors (Belgium, the Netherlands and the UK) with clearly diverging performance‐management cultures, and exploring the extent to which they rely upon joint and aligned initiatives.     

Evaluation of a multi-site program designed to strengthen relational bonds for siblings separated by foster care

Sibling relationships in foster care settings have received increased attention in recent years. Despite growing evidence regarding the protective potential of sibling relationships for youth in care, some sibling groups continue to experience foster care related separation, and few programs exist to address the needs of these youth.This study describes and evaluates Camp To Belong, a multi-site program designed to provide short-term reunification to separated sibling groups through a week-long summer camp experience. Using a pre-test post-test survey design, this paper examines changes in youth ratings of sibling conflict and sibling support across camps located in six geographically distinct regions of the United States. The effects of youth age, number of prior camp exposures, and camp location were tested using multilevel modeling procedures.Findings suggest that participation in Camp To Belong may reduce sibling conflict, and improvements in sibling support are noted for youth who have had prior exposure to the camp’s programming. Camp-level variance in the sibling support outcome highlight the complex nature of relationships for siblings separated by foster care, and suggest the need for additional research. Lessons learned from this multi-site evaluation and future directions are discussed.

C330. The variability of evaluations of speculative ideas

This article reports results of an extensive simulation study which investigated the performances of some commonly used methods of estimating error rates in discriminant analysis. Earlier research papers limited their comparisons of these methods to independent training data. This study allows for a simple auto-regressive dependence among the training data. The results suggest that the estimation methods based on the normal distribution perform adequately well under conditions of negative or mild positive correlation in the data, and small dimensions (p) of the observation vectors. For large p or strong positive correlation structures the conclusion is that one of the better non-parametric methods should be used. Special circumstances and conditions which notably affect the relative performances of the methods are identified.     

The role of titles in enhancing data visualization

Many in the data visualization and evaluation communities recommend conveying the message or takeaway of the visualization in the visualization's title. This study tested that recommendation by examining how informative or generic titles impact a visualization’s visual efficiency, aesthetics, credibility, and the perceived effectiveness of the hypothetical program examined. Furthermore, this study tested how simple or complex graphs, and positive, negative, or mixed results (i.e., valence of the results) affected outcomes. Participants were randomly assigned to one of 12 conditions, representing a 2 (graph: simple or complex) x 2 (title: generic or informative) x 3 (valence: positive, negative, mixed) between-subjects study. The results indicated that informative titles required less mental effort and were viewed as more aesthetically pleasing, but otherwise did not lead to greater accuracy, credibility, or perceived effectiveness. Furthermore, titles did not interact with graph type or the valence of the findings. While the results suggest it is worthwhile to consider adding an informative title to data visualizations as they can reduce mental effort for the viewer, the intended goal of the visualization should be taken into consideration. Considering the goal of the visualization can be a deciding factor of the type of graph and title that will best serve its intended purposes. Overall, this suggests that data visualization recommendations that impact evaluation reporting practices should be scrutinized more closely through research.
