Report on the implementation and evaluation of an interprofessional learning programme for inter‐agency child protection teams

Effective collaborative working between the different professions and agencies working to safeguard children is essential. Lack of knowledge of others' roles, perceived differences in status and expertise, and negative stereotypes are examples of why this can be difficult to achieve. A facilitated interprofessional learning (IPL) programme was implemented to assess if such an intervention could overcome some of the barriers to effective interprofessional and inter‐agency team working. Six teams based in primary and secondary care trusts took part with participants from health, education, police and social services. Quantitative and qualitative data were collected from individual participants using a pre‐validated team climate inventory and reflective statements. Findings from this study demonstrate statistically significant changes in five out of six categories in the inventory. Reflective statements suggested that overall the programme offered a positive learning experience at both an individual and team level. The importance of outside facilitation to maintain the team's momentum was acknowledged, as was the difficulty of maintaining a good level of activity once the programme had ended. Nevertheless, the IPL programme provided a timely opportunity to reflect upon the interprofessional and inter‐agency team working needed within Children's Trusts and the implications for staff involved with regard to skills development.

Efficiency Wages,Productivity and Simultaneity: A Meta-Regression Analysis

This study reports a meta-analysis of 75 estimates of the efficiency-wage effect. It reveals a strong efficiency-wage effect that depends upon whether researchers control for potential simultaneity between wages and productivity. Studies that control for simultaneity tend to report stronger effects. Clear evidence of publication selection is also found. E24, J30.

Women Rule: Gendered Leadership and State Supreme Court Chief Justice Selection

ABSTRACT

While women are underrepresented in many political institutions and leadership positions, nearly half of state supreme court chief justices are women. Is there something about the role of state supreme court justice that facilitates the recruitment of women to this important political position? We examine whether the selection of a woman chief is driven by the court’s institutional need for women’s leadership style or simply the supply of qualified justices. We find that ideological diversity drives demand for a woman chief. A supply of experienced women justices also has a significant impact on likelihood of selection.     

The exponentiated reduced Kies distribution: Properties and applications

Here we consider an exponentiated version of the reduced Kies distribution and discuss some of its properties. The parameters of the distribution are estimated by the method of maximum likelihood and illustrated with the help of certain real-life data sets. Asymptotic behavior of the maximum likelihood estimators of the parameters of the distribution is also studied by using certain simulated data sets.     

Model selection consistency of U-statistics with convex loss and weighted lasso penalty

In the paper we consider minimisation of U-statistics with the weighted Lasso penalty and investigate their asymptotic properties in model selection and estimation. We prove that the use of appropriate weights in the penalty leads to the procedure that behaves like the oracle that knows the true model in advance, i.e. it is model selection consistent and estimates nonzero parameters with the standard rate. For the unweighted Lasso penalty, we obtain sufficient and necessary conditions for model selection consistency of estimators. The obtained results strongly based on the convexity of the loss function that is the main assumption of the paper. Our theorems can be applied to the ranking problem as well as generalised regression models. Thus, using U-statistics we can study more complex models (better describing real problems) than usually investigated linear or generalised linear models.     

The performance of model averaged tail area confidence intervals

We investigate the exact coverage and expected length properties of the model averaged tail area (MATA) confidence interval proposed by Turek and Fletcher, CSDA, 2012, in the context of two nested, normal linear regression models. The simpler model is obtained by applying a single linear constraint on the regression parameter vector of the full model. For given length of response vector and nominal coverage of the MATA confidence interval, we consider all possible models of this type and all possible true parameter values, together with a wide class of design matrices and parameters of interest. Our results show that, while not ideal, MATA confidence intervals perform surprisingly well in our regression scenario, provided that we use the minimum weight within the class of weights that we consider on the simpler model.     

不均等选择概率下的加权调整研究

从不均等选择概率的角度,提出两类常见的权数调整类型及其调整方法:一是规模调整,使得样本单元权数之和等于总体规模;二是结构调整,使得样本结构和总体结构一致,并构造出加权调整的设计效应模型,应用于复杂样本设计。案例分析显示,加权调整往往导致设计效应变大,带来负的效应,但校准调整能降低设计效应,提高估计精度。     

中国省域创新创业环境评价指标体系的构建研究——对全国31个省级单位的测评

围绕创新创业环境的内涵,梳理了影响创新创业环境的六类主要因素,归纳潜在指标;对各潜在指标进行"聚类—因子—权重"综合分析,提炼影响创新创业环境的主要因子,构建出以6个一级指标和20个二级指标为核心的创新创业环境评价指标体系,并建立评价模型。以中国各省为样本,对全国31个省级单位的创新创业环境在2014年的状况进行测评排序。依据各省创新创业环境综合得分情况,得出全国31省2014年创新创业环境的地理空间分布图。分地区评价结果显示,东部地区创新创业环境具有明显优势,中部、东北和西部地区发展空间较大。从准则层指出各个地区优化创新创业环境的着力点。
