本文通过从设计理念、运行机制、模式的优势等方面深入探讨了“以社工中心整合各方资源,优化现有养老资源配置”的养老模式。     

从价值冲突到价值整合 ——当代中国青年亚文化现象解读

当代中国青年亚文化与主流文化的价值冲突主要体现在三个方面：即个人主义价值观与集体主义价值观的冲突、个人价值选择多样性与社会要求统一性的冲突、此岸肉体价值和彼岸精神价值的冲突。对待这种冲突,一是要以科学的态度进行引导和整合;二是要切实建构起符合时代要求的社会价值观体系;三是要充分发挥社会主义核心价值体系的引领作用。     

Children discharged from kin and non-kin foster homes: Do the risks of foster care re-entry differ?

This study investigates whether the type of pre-discharge placement, kinship versus non-kinship foster care, has a net impact on children's likelihood of re-entering substitute care after controlling for possible selection biases through the use of regression adjustment and propensity score matching (PSM). Children in kin and non-kin foster care are compared on their rates of foster care re-entry, using bivariate comparisons and accelerated failure time (AFT) models. Lower rates of foster care re-entry after reunification from kinship homes are attributed to differences in child characteristics at removal, greater stability of kin placements, and gate-keeping functions that agencies and courts exercise over discharge and re-entry options. Children adopted from kinship and non-kinship homes exhibit similar re-entry rates, but the results for legal guardianship are mixed.     

Implications and Applications of a Behavior Systems Perspective

Improving employee performance in an organization seems to cycle back and forth among six broad approaches. Rather than debate which approach is most effective, the argument is made that each approach is simply one aspect of a larger behavior system. The ultimate answer, then, is to integrate these approaches within an overarching behavior systems perspective. A potential behavior systems perspective is described as well as its implications for employee performance improvement. An expansion of OBM graduate curricula is recommended that includes more diverse improvement strategies.     

A boosting inspired personalized threshold method for sepsis screening

Sepsis is one of the biggest risks to patient safety, with a natural mortality rate between 25% and 50%. It is difficult to diagnose, and no validated standard for diagnosis currently exists. A commonly used scoring criteria is the quick sequential organ failure assessment (qSOFA). It demonstrates very low specificity in ICU populations, however. We develop a method to personalize thresholds in qSOFA that incorporates easily to measure patient baseline characteristics. We compare the personalized threshold method to qSOFA, five previously published methods that obtain an optimal constant threshold for a single biomarker, and to the machine learning algorithms based on logistic regression and AdaBoosting using patient data in the MIMIC-III database. The personalized threshold method achieves higher accuracy than qSOFA and the five published methods and has comparable performance to machine learning methods. Personalized thresholds, however, are much easier to adopt in real-life monitoring than machine learning methods as they are computed once for a patient and used in the same way as qSOFA, whereas the machine learning methods are hard to implement and interpret.     

Symbolic computation for approximating distributions of some families of one and two-sample nonparametric test statistics

A conditional saddlepoint approximation was provided by Gatto and Jammalamadaka (1999) for computing the distribution function of many test statistics based on dependent quantities like multinomial frequencies, spacing frequencies, etc. The considerable complexity of the formulas involved can be bypassed by symbolic computation. This article illustrates the effectiveness of symbolic computation to evaluate the saddlepoint approximation for the likelihood ratio, the exponential score, and the Wald-Wolfowitz test statistics. The case of composite hypotheses is also discussed.     

论标准分数在确立学生多科考试总成绩相对位次中的应用

标准分数是将原始卷面分数经过某种数学公式转换后,扣除难度和区分度等客观因素影响而只考虑主观因素影响的一种相对分数.在确立学生多科考试总成绩相对位次的应用方面(如招生、评优、评奖等),由于仅仅考虑孝生总成绩的相对高低,因此标准分数较原始卷面分数显得更为恰当、合理、客观、公正.     

On the Bootstrap of the Maximum Score Estimator

This paper shows that the bootstrap does not consistently estimate the asymptotic distribution of the maximum score estimator. The theory developed also applies to other estimators within a cube‐root convergence class. For some single‐parameter estimators in this class, the results suggest a simple method for inference based upon the bootstrap.     

基于改进得分函数的直觉模糊多属性决策方法

针对属性权重信息完全未知的直觉模糊多属性决策问题进行了探究,提出了一种综合考虑隶属度、非隶属度以及犹豫度的新的得分函数,利用改进的得分函数将传统的熵权法推广到直觉模糊领域,为属性权重完全未知的直觉模糊多属性决策问题提供了一个新的排序方法。实际的铁路冻害整治算例进一步说明该方法的可行性和有效性。     

网络游戏成瘾量表研究——事件相关脑电位辅助分析

在我国网络游戏产业发展迅猛,网民数量持续高速增长,但同时也出现了网游玩家沉迷于网络游戏中而产生心理依赖的成瘾症状.目前对网络成瘾的概念、界定指标和测量工具都存在较大争议,缺乏网络成瘾界定的系统研究.本研究在以往多种量表的基础上,采用事件相关脑电位方法,采用成瘾Stroop实验范式,找到了可以区分网络游戏成瘾者和正常网络使用者的客观电生理指标,验证了这个分类.通过对这群已经被验证了的两组被试的问卷测量,形成了"网络游戏成瘾量表",并依据测量结果,给出了推断被试是否成瘾的总分分界值.然后,采用重测信度方法,验证了量表的稳定性和可靠性.最后,用测量预留的成瘾被试,验证了"网络游戏成瘾量表"的有效性.
