Whether high quantities of center-based care cause behavior problems is a controversial question. Studies using covariate adjustment for selection factors have detected relations between center care and behavior problems, but studies with stronger internal validity less often find such evidence. We examined whether within-child changes in hours in center-based care predicted changes in externalizing problems in toddlers and preschoolers (N = 10,105; 49% female; data collection 1993–2012) in seven studies, including from Germany, Netherlands, Norway, two from Canada and two from the U.S. Race/ethnicity data were only collected in the United States (57% and 80% White; 42% and 13% African-American; 1.2% and 5% Latinx). Meta-analyses showed no association (r = .00, p = .88) between hours in center-based care and externalizing problems. 相似文献

Oral Cancer is one of the five leading sites of cancer in Indian population. The circulating immune complexes were investigated
in 100 serum samples of 60 oral cancer patients having different grades of the disease and 40 patients with precancerous lesions
obtained from Nair Hospital Dental collage, Mumbai. The results obtained were compared with those of group of 40 healthy blood
donors. Elevated levels of Circulating Immune Complexes were observed in oral cancer patients and patients with oral precancerous
lesions. 92% positive samples were observed in well differentiated squamous cell carcinoma whereas 100% positive samples were
observed in both moderately and poorly differentiated squamous cell carcinoma. Oral leukoplakia and oral submucous fibrosis
showed 15% and 90% positivity respectively. Increased level of Circulating Immune complexes in high grade tumor suggest that
Circulating Immune complexes is likely to contribute in evaluating the degree of malignancy, but follow up study is needed
to draw any conclusion regarding it's prognostic role 相似文献

The three exploratory studies reported here investigate the role of love styles in the early stages of romantic relationships. Study 1 (N = 108) had subjects rate and rank 14 characteristics of prospective romantic partners. As expected, individual's love style scores were related to the characteristics people report as desirable in a relational partner. Several of these effects, however, were moderated by sex. Study 2 (N = 173) revealed that scores on love styles were associated with ratings of opening lines and intensification strategies. None of these effects were moderated by sex. Study 3 (N = 137) investigated the association between love styles and ratings of secret tests among individuals currently involved in a romantic relationship. The results indicated that love styles were associated with ratings of secret tests. These data add to a growing body of literature suggesting that love styles are associated with individual differences in relational and communicative behavior across the life span of romantic relationships. 相似文献

In this paper we focus on the lived experiences of multidisciplinary scholars as we navigated and coalesced into a productive, interdisciplinary collaboration. We pull from our foundations in feminist methodology and provide excerpts from personal journals and reflexive group interviews to provide a behind-the-scenes account of the inner workings of a feminist research group. While sharing a common research goal, each member negotiated her personal, conceptual, and epistemological stances as we produced an effective, interdisciplinary pastiche. Throughout this process, we worked to create a non-hierarchical atmosphere, continuously and ethically questioned our methods, and incorporated reflexivity in the research processes. In addition to sharing our past experiences, we note challenges we encountered and offer practical suggestions based on the lessons we learned through this collaboration. 相似文献

The study examined the ability of deaf and hearing students at the college and middle school levels to discern and apply knowledge of printed word morphology. There were 70 deaf and 58 hearing participants. A two-part paper-and-pencil test of morphological knowledge examined subjects' ability to (a) perceive segmentation of morphemes within printed words and (b) recognize meanings associated with various printed morphemes. The hearing college students performed best on every dependent measure of the two-part test. The deaf college students scored significantly lower than the hearing college students but similarly to the hearing middle school students. Deaf middle school students consistently scored the lowest on both parts of the test. While all students' performance declined as the difficulty of the morphemic content increased within both tasks, the decline was greatest among middle school deaf students. Although segmentation and semantic analysis skills necessary to morphographic decoding were apparent in the deaf students, their mastery levels fell significantly below those of the hearing subjects. 相似文献

A nationwide purposive sample of secondary vocational educators completed a questionnaire that examined practices and perceptions toward grading students with disabilities. A variety of grading methods was reportedly used, but over two-thirds of respondents included a competency-based grading component. An overwhelming majority believed that student effort should be used to determine grades. Two-thirds of vocational educators had never been involved in their students' IEP development. The most common changes teachers have made over time in their grading practices included becoming more flexible and individualized in grading. Overall, teachers displayed moderately positive attitudes toward grading students with disabilities. 相似文献

The term ‘information’ is seldom given a careful definition and is in practice used in more than one sense. In particular there is often a failure to distinguish ‘information’ from concepts such as ‘knowledge’, ‘belief’ and ‘meaning’. One attempt to build a suitable conceptual scheme with a firm philosophical basis has been made by Dretske. In corporate contexts, the meaning and significance of information can be seen as lying in its contribution to the maintenance and development of ‘systems’ of activities. It follows that a competent analysis of corporate information requirements and a specification of the characteristics of data collection, communication and processing needed to satisfy them, both depend on an appropriate form of systems analysis. The methods used by Checkland and Wilson provide means of exploring the requirements, while the approaches of Beer and Espejo define patterns of information flow necessary for their realization. As advanced techniques of information processing develop, clearer understanding of such approaches and their theoretical basis will become important in exploiting their potential. 相似文献

To further the understanding of the effects of early experiences, 9-month-old infants were observed during a frustration task. The analytical sample was composed of 348 linked triads of participants (adoptive parents, adopted child, and birth parent[s]) from a prospective adoption study. It was hypothesized that genetic risk for externalizing problems and affect dysregulation in the adoptive parents would independently and interactively predict a known precursor to externalizing problems: heightened infant attention to frustrating events. Results supported the moderation hypotheses involving adoptive mother affect dysregulation: Infants at genetic risk showed heightened attention to frustrating events only when the adoptive mother had higher levels of anxious and depressive symptoms. The Genotype × Environment interaction pattern held when substance use during pregnancy was considered. 相似文献
