Child protection cases,one size fits all? Cluster analyses of risk and protective factors

BackgroundTo provide effective tailor made case management in Child Protection Services (CPS) a insight is needed into the specific characteristics of the target group. Using the ecological perspective of maltreatment, this study explored poorly known characteristics of the CPS population.ObjectiveTo distinguish CPS subgroups based on risk and protective factors enables tailor made case management that fits the specific needs of these subgroups.Participants and settingWe studied 250 Dutch CPS cases of family supervision by court order that had completed the LIRIK and Action Plan checklists in August 2014–March 2015.MethodsThis quantitative study analyzed risk and protective factors for children and parents reported in client files. Subgroups were identified by two-step cluster analyses. Chi-square analyses identified relations between parental risk subgroups and other groups.ResultsBuilding on the interplay between risk and protective factors on the levels of child, parent and environment, we found five distinct subgroups in the CPS population. The most vulnerable is parents with multiple problems (31%) or socio-economic problems (13%). Parts of both subgroup have limited protective factors. Parents with major life events (16%) or poor parenting (13%) are characterized by single-level problems. One subgroup (28%), the unaccepted, has no parental risk factors registered.ConclusionsStudying client files can lead to a better understanding of the healthcare needs of the CPS population. To develop and implement more effective case management requires constant dialogue between science, policy, and the experiences of both clients and professional.

Spiritual beliefs among Chinese junior high school students

Objective: To explore the characteristics of the spiritual beliefs among junior high school students. Method: 431 junior high school students are measured by Students’ Basic Information Questionnaire (SBIQ) and Middle School Students’ Spiritual Beliefs Questionnaire (MSSSBQ). Results: (1) The overall characteristics of the spiritual beliefs among junior high school students are as follows: social beliefs rank first, practical faith second, and supernatural beliefs last. The ranks of the seven beliefs from high to low are nationalism, political conviction, family’s doctrine, life worship, religious beliefs, money/material and gods worship. (2) Boy students have higher political conviction and money/material faith than girl students. Girl students have higher religious beliefs than boy students. (3) On the beliefs of money/material and life worship, students in Grade 9 take the first place, Grade 8 second and Grade 7 last. (4) Non-student cadres have stronger money/material faith than cadres. (5) League members have higher political beliefs than non-members. (6) Students who are good at studies have stronger national faith than students who are average or poor at studies. Students who are poor at studies have stronger money/material faith than other students. Conclusion: The spiritual beliefs of junior high school students are positive. __________ Translated from Psychology Development and Education, 2005:2.     

高管资源断裂带对企业跨界技术并购创新绩效的影响研究

文章以2007-2018年沪深A股上市公司的跨界技术并购事件为研究样本,采用所对应的2007-2020年的数据,检验了基于资源属性的团队内部分化对跨界技术并购创新绩效的影响效应。研究发现,高管资源断裂带能够促进跨界技术并购创新绩效的提升,并且资源子团队平衡性和数量等相对分布均能够促进资源断裂带对跨界技术并购创新绩效的正向影响。进一步发现,在规模相对较小、股权集中度相对较低、位于传统文化影响较大的地区的企业中,资源断裂带对跨界技术并购的影响作用更强,资源子团队平衡性与数量这两个结构属性的正向调节作用更强。     

The role of gene DCDC2 in German dyslexics

Dyslexia is a complex reading and writing disorder with a strong genetic component. In a German case-control cohort, we studied the influence of the suspected dyslexia-associated gene DCDC2. For the first time in a German cohort, we describe association of a 2445 basepair deletion, first identified in an American study. Evidence of association for three DCDC2 single nucleotide polymorphisms (rs807724, rs793862, rs807701), previously identified in German or American cohorts, was replicated. A haplotype of these polymorphisms showed evidence for association as well. Thus, our data further corroborate association of DCDC2 with dyslexia. Analysis of functional subgroups suggests association of investigated DCDC2 variants mainly with nondysphonetic, nonsevere, but probably dyseidetic (surface) dyslexia. Based on the presumed function of DCDC2, our findings point to a role of impaired neuronal migration in the etiology of the disease.
