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. 相似文献

Most scientific endeavors require science process skills such as data interpretation, problem solving, experimental design, scientific writing, oral communication, collaborative work, and critical analysis of primary literature. These are the fundamental skills upon which the conceptual framework of scientific expertise is built. Unfortunately, most college science departments lack a formalized curriculum for teaching undergraduates science process skills. However, evidence strongly suggests that explicitly teaching undergraduates skills early in their education may enhance their understanding of science content. Our research reveals that faculty overwhelming support teaching undergraduates science process skills but typically do not spend enough time teaching skills due to the perceived need to cover content. To encourage faculty to address this issue, we provide our pedagogical philosophies, methods, and materials for teaching science process skills to freshman pursuing life science majors. We build upon previous work, showing student learning gains in both reading primary literature and scientific writing, and share student perspectives about a course where teaching the process of science, not content, was the focus. We recommend a wider implementation of courses that teach undergraduates science process skills early in their studies with the goals of improving student success and retention in the sciences and enhancing general science literacy. 相似文献

Researchers debate whether one represents the magnitude of a fraction according to its real numerical value or just the discrete numerosity of its numerator or denominator. The present study examined three effects based on the notion that people possess a mental number line to explore how children represent fractions when they compare fractions with common numerators. Specifically, the effect of the spatial numerical association of response codes (SNARC), the distance effect and the size effect in representing fractions were examined in a sample of 72 sixth graders, who successfully solved the fraction comparison task with a real number (.2) or a fraction (1/5) as the reference. Results showed that in the fraction-reference group (1/5 as the reference), there was a significant reverse SNARC effect and a distance effect between the denominators of the target fractions and the reference fraction; in the real number-reference group, the three effects were also observed. These results revealed that both groups used the mental number line to represent fractions and did not represent their real numerical values but rather the discrete numerosities of denominators when comparing fractions with common numerators. It seems that the way people represent fractions may depend on their strategy choices. 相似文献

Kinetics of Thermal‐Degradation of Betanins: A Teaching Mini‐Project for Undergraduates Employing the Red Beet 下载免费PDF全文
Clarissa H. Rosa Francine Antelo Gilber R. Rosa 《Journal of Food Science Education》2018,17(4):104-110
A 4‐week mini‐project is proposed for an experimental Physical Chemistry course applied in Food Science training. Activities include preparation of beet extract for the extraction of betanins and analysis of the kinetics of betanins in thermal degradation at three temperatures (60, 70, and 80 ºC). In addition to developing common laboratory routines (for example, dilution and use of the UV‐Vis spectrophotometer), students will have contact with the usual procedure for evaluating use of natural dyes in the food industry. 相似文献

Simplest Shapes First! But Let's Use Cognitive Science to Reconceive and Specify What “Simple” Means
Children's informal and formal learning experiences with geometric shapes currently result in misconceptions that persist into adulthood. Here, we combine research from mathematics education as well as cognitive science pertaining to concepts, categories, and learning strategies to propose a more optimal progression that is better specified and justified than the current standards. To do so, we reframed what constitutes a “simple” shape from perceptual simplicity to simplicity of properties. Our Property-Based Shape Sequence uses property-based criteria of what makes shapes “simple” and progresses in a way that affords opportunities for learners to develop hierarchical conceptions of two-dimensional and three-dimensional shapes. Our goals are threefold: (1) recommend an optimal, mathematically-correct shape learning sequence, (2) correct misconceptions that adults and children harbor about shapes, and (3) encourage cross-disciplinary collaborations between mathematics education and psychology researchers to validate the proposed learning sequence. 相似文献

Just like adults, children of all ages need time and understanding in order to process the concept of death and dying. This process is much different for children than it is for adults. There are 4 components relative to children's understanding of death: (a) the irreversibility factor, (b) finality, (c) inevitability, and (d) causality. These 4 components relate directly to the developmental level of the child at the time the death occurs. Knowing how children's concept of death is constructed provides parents and caregivers important information and helps them respond more sensitively to what children might feel and experience. This article provides an overview of how children understand death, concrete strategies for talking to children about death, and suggestions for teachers about how to help children through grief and mourning. 相似文献

Drawing on participant-observation research conducted in one core urban and one affluent suburban public school, the author argues that critical educational theorists should devote more attention to differential structural constraints on pedagogic choice. Teachers at the urban North End Community School make pedagogic choices that reinforce social hierarchies. They do so, in part, in order to enable their students to manage a series of risks and dangers associated with concentrated urban poverty. The evidence presented suggests that changing the role power plays in urban public schooling requires changing not only the choices individual teachers make, but also educational and other institutional constraints on pedagogic practice. 相似文献
