A qualitative study on the pros and cons of ethnically matching culturally and linguistically diverse (CALD) client families and child protection caseworkers

A review of the literature indicated that empirical research into the advantages and disadvantages of ethnically matching child protection caseworkers and culturally and linguistically diverse (CALD) client families is not extensive. The main aim of this study was to address this gap. Qualitative interviews were conducted with 29 CALD client families and 17 child protection caseworkers (as part of a larger study). It was found that if CALD families fear a breach of confidentiality (because of cultural reasons to protect the family's privacy and name), and this fear exceeds the two main benefits of ethnic matching – namely, that it helps overcome language barriers and provides (cultural) sensitivity – then they are likely to prefer a non-matched caseworker. This may be a challenge in child protection practice if the pool of culturally competent caseworkers is small. Another challenge identified was when CALD families preferred an ethnic match but was seen by case managers as a risk to the accurate assessment of a child's wellbeing because the caseworker was over-identifying with the client family. Thus, the provision of a culturally sensitive service can be at odds with the need to protect children from harm. This issue is seen as best addressed on a case by case basis. This study is significant because it has shown that ‘over-identification’ is an important work practice issue in this matter. It has also used empirical evidence to inform best practice principles regarding ethnic matching.     

同乡的力量：同乡聚集对农民工工资收入的影响

中国的城乡流动中存在同一籍贯或同一来源地的农村流动人口的就业聚集现象--“同乡聚集”。本研究使用2010年珠三角和长三角外来务工者调查的数据,采用倾向分数匹配和异质性干预模型等方法,考察了以籍贯为族群基础的同乡聚集对城市农民工经济收入的影响。研究发现,尽管同乡聚集者的收入优势受到异质性和自我选择机制的影响,但同乡聚集仍有助于提高农民工的工资收入。越倾向于同乡聚集的农民工,从同乡聚集中获得的收入回报越高。     

“言文一致”与方言小说——清末小说中的“方言”问题

与“言文一致”、“小说界革命”的思潮密切相联系,晚清对用方言写小说形成一个理论自觉,也出现一批方言小说,其中以吴语小说和京语小说最具代表,可谓别开生面。但小说中大量运用方言来模拟口语的逻辑与小说“开民智”要求的普及性,以及小说语言的艺术性形成矛盾。重视小说艺术性的小说家就提出“另为一种言语”和“另造一种通行文字”的观点,这种兼顾口语化、普泛性和艺术性的白话书面语革新,才符合“官话一国语”建构的路径,为小说语言的由俗变雅提供了可能,也修正了方言小说的弊端,但这一理论真正的实现则在五四时期。     

电子易货资源匹配模型研究

针对电子易货市场资源匹配问题,通过系统分析易货市场中资源分类情况以及匹配的目标要求,得到资源匹配的数学模型;运用网络流理论对问题模型进行转化,把资源匹配数量最大的目标转换成有流量限制的网络最小费用流问题,依此建立网络模型;最后,以制造业和服务业之间的易货进行案例分析建模,用winQSB软件求解验证。结果表明,该模型的应用提高了易货资源匹配的运算效率和准确性。     

Stability and Preference Alignment in Matching and Coalition Formation

We study matching and coalition formation environments allowing complementarities and peer effects. Agents have preferences over coalitions, and these preferences vary with an underlying, and commonly known, state of nature. Assuming that there is substantial variability of preferences across states of nature, we show that there exists a core stable coalition structure in every state if and only if agents' preferences are pairwise‐aligned in every state. This implies that there is a stable coalition structure if agents' preferences are generated by Nash bargaining over coalitional outputs. We further show that all stability‐inducing rules for sharing outputs can be represented by a profile of agents' bargaining functions and that agents match assortatively with respect to these bargaining functions. This framework allows us to show how complementarities and peer effects overturn well known comparative statics of many‐to‐one matching.     

农业保险排斥对农民收入的影响：基于倾向值匹配的异质性研究

我国存在较严重的农业保险排斥,对农民收入产生了一定影响。采用2015-2016年北方6省12县种植业保险的调研数据,利用倾向得分匹配法纠正可能存在的样本选择性偏误,系统考察了农业保险排斥对农民收入的影响。实证结果表明：农业保险排斥对农民收入有显著负向影响,受排斥农户与未受排斥农户的农业收入差异为6%左右。考虑异质性后的结果进一步表明,未受排斥的年轻农户和规模扩大型农户农业收入增长明显。此外,相较于高受灾农户,未受排斥的低受灾农户因为受灾和补偿概率较低,农业保费成为农业额外成本从而降低了收入。提出应持续推进政策性农业保险“提标、扩面、增品”,降低农村农业保险排斥,充分发挥农业保险在防风险、稳收入中的作用。     

IT服务供需双边匹配的模糊多目标决策方法

描述了IT服务外包中的供给方与需求方的双边匹配决策问题。为了解决该问题,针对IT服务的供给方和需求方分别给出的语言满意度评价信息,将语言评价信息转化为三角模糊数并进行多指标信息的集结运算。在此基础上,考虑以供给方和需求方双方满意度最大为目标,构建了IT服务供需双边匹配的模糊多目标优化模型,并采取将模糊多目标优化模型转化为单目标线性规划模型的方式进行求解得到匹配结果。实例计算表明,提出的方法具有可行性和实用性。     

类型学差异对语言接触中声调匹配及回归的影响

实验语音分析是研究维族汉语声调匹配和回归规律的有效方法。维族汉语语料声学分析表明,声调完成有序化匹配的时间比声母、韵母完成匹配的时间要长;维族汉语单字调的匹配、回归是分阶进行的;维族汉语双音节声调模式受母语音高重音模式潜在制约;维族汉语"维腔维调"现象是维汉语言类型学差异在语言接触中的表现。

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.
