The association of child abuse and neglect with adult disability in schizophrenia and the prominent role of physical neglect

ObjectiveTo assess long-lasting effects of childhood trauma on the functional outcome of adult patients diagnosed with schizophrenia.MethodNinety-nine stable patients with schizophrenia followed in an outpatient program at a public university hospital in Porto Alegre, southern Brazil, were investigated for childhood traumatic experiences by the Childhood Trauma Questionnaire (CTQ) and for functional impairment by the World Health Organization Disability Assessment Schedule (WHO/DAS). The schizophrenia diagnosis was assessed by ICD-10 and DSM-IV criteria according to the Operational Criteria Checklist for Psychotic Illness (OPCRIT).ResultsChildhood trauma in general was associated with increased disability in adulthood, reflected by impaired Overall Behavior (p = .023) and Global Evaluation (p = .032). Analysis of specific traumatic domains revealed that increased childhood physical neglect was associated with functional impairment in Overall Behavior (p < .000), Social Role Performance (p = .037) and Global Evaluation (p = .014). Higher emotional abuse was associated with impaired Overall Behavior (p = .026), and higher emotional neglect with poor Global Evaluation (p = .047). Additionally, earlier onset of illness was associated with lower level of functioning evidenced by impairment in Overall Behavior (p = .042). Linear regression using WHO/DAS sections (Overall Behavior, Social Role Performance and Global Evaluation) as dependent variables and CTQ subscales indicated that only physical neglect had an effect on adult functionality.ConclusionsChildhood trauma was associated with functional and social impairment in adult patients with schizophrenia. Specific types of abuse and neglect, such as physical neglect and emotional abuse and neglect, influenced disability, and the most robust association was physical neglect. Studies involving more patients, with normal controls and additional measurements of biological liability, should be conducted to confirm this association and to increase the understanding of gene-environment relationship in schizophrenia and pathways to disability.Practice implicationsFurther investigation is warranted to clarify the association between childhood trauma and disability in schizophrenia, as well as to develop standardized instruments for the assessment of trauma and earlier detection of risk along with education of patients and families about adequate care, in an effort to reduce the incidence of disability in schizophrenia.     

The relation of knowledge of textual integration devices to expository text comprehension under different assessment conditions

In this study we propose a theoretical construct (called rhetorical competence) that represents the ability of readers to detect, understand, and use the linguistic cues or discourse markers that texts contain. We measure one of the three postulated components of rhetorical competence (knowledge of textual integration markers), assessing whether readers correctly interpret these markers while reading. The influence of this skill on reading competence is examined in a correlational study of 185 sixth-grade pupils (aged 11–12 years) using different assessment materials (a standardized test and an academic text) and reading conditions (habitual and aided). Multiple regression analyses of the data indicate that knowledge of textual integration devices makes a significant independent contribution to expository text comprehension under most assessment conditions when the effects of working memory, prior knowledge, and word recognition skills are controlled.     

Google Scholar,Web of Science,and Scopus: A systematic comparison of citations in 252 subject categories

Despite citation counts from Google Scholar (GS), Web of Science (WoS), and Scopus being widely consulted by researchers and sometimes used in research evaluations, there is no recent or systematic evidence about the differences between them. In response, this paper investigates 2,448,055 citations to 2299 English-language highly-cited documents from 252 GS subject categories published in 2006, comparing GS, the WoS Core Collection, and Scopus. GS consistently found the largest percentage of citations across all areas (93%–96%), far ahead of Scopus (35%–77%) and WoS (27%–73%). GS found nearly all the WoS (95%) and Scopus (92%) citations. Most citations found only by GS were from non-journal sources (48%–65%), including theses, books, conference papers, and unpublished materials. Many were non-English (19%–38%), and they tended to be much less cited than citing sources that were also in Scopus or WoS. Despite the many unique GS citing sources, Spearman correlations between citation counts in GS and WoS or Scopus are high (0.78-0.99). They are lower in the Humanities, and lower between GS and WoS than between GS and Scopus. The results suggest that in all areas GS citation data is essentially a superset of WoS and Scopus, with substantial extra coverage.     

Gender matters in transition to adulthood: A survey study of adolescents with disabilities and their families

This survey study explored gender differences in transition imperatives and opportunities for youth with disabilities (N = 521). Results indicated that males and females differ in terms of the adult outcomes they hope to achieve, transition training opportunities they have received, and their access to teachers and other nonfamilial adults to assist them. Youth and parents who responded to the survey indicated that gender stereotypes continue to exist and that these stereotypes result in lowered expectations for girls. Gender stereotypes were found to vary by ethnicity. Access to health insurance and a good doctor were rated as top priorities for all youth transitioning to adulthood. Implications for educators, psychologists, and counselors are discussed. © 2008 Wiley Periodicals, Inc.

A literature review on knowledge management in SMEs

This paper provides a systematic review of the literature on knowledge management (KM) in small and medium enterprises (SMEs) and SME networks. The main objective is to highlight the state-of-the-art of KM from the management point of view in order to identify relevant research gaps. The review highlights that in recent years the trend of papers on the topic is growing and involves a variety of approaches, methodologies and models from different research areas. The vast majority of papers analysed focus on the topic of KM in the SME while there are only few papers analysing KM in networks populated by SMEs. The content analysis of the papers highlights six areas of investigation from which were derived ten research questions concerning three perspectives: the factors affecting KM; the impact of KM on firm’s performance; the knowledge management systems.     

Modified team‐based learning strategy to improve human anatomy learning: A pilot study at the Universidad del Norte in Barranquilla,Colombia

As part of an institutional program sponsored by the Centre for Teaching Excellence at the Universidad del Norte, Barranquilla, Colombia, we developed an educational research study on two sessions of human anatomy in which we combined team‐based learning (TBL) and the use of iPads. Study data included the TBL, assessments applied during the course, student's grades on mid‐term examinations and students' perceptions of their experiences. Students reported a positive attitude toward the use of the TBL sessions, and the results showed a significant improvement in their learning between the first and second sessions. Significantly positive correlations (P < 0.05) were obtained between (a) the individual students' readiness test performance 1 and mid‐term examination 1, (b) the individual readiness test performances from Session 1 to Session 2, and (c) the group readiness test performances from the first and second sessions. These results point to positive learning experiences for these students. Analyses of the students' reflections on their activities also pointed toward future challenges.

Polytopic invariant and contractive sets for closed-loop discrete fuzzy systems

In this work a procedure for obtaining polytopic λ-contractive sets for Takagi–Sugeno fuzzy systems is presented, adapting well-known algorithms from literature on discrete-time linear difference inclusions (LDI) to multi-dimensional summations. As a complexity parameter increases, these sets tend to the maximal invariant set of the system when no information on the shape of the membership functions is available. λ-contractive sets are naturally associated to level sets of polyhedral Lyapunov functions proving a decay-rate of λ. The paper proves that the proposed algorithm obtains better results than a class of Lyapunov methods for the same complexity degree: if such a Lyapunov function exists, the proposed algorithm converges in a finite number of steps and proves a larger λ-contractive set.
