The present study examined predictors of discrepancies between mothers’, fathers’, and teachers’ ratings of 3-year-old children's hyperactivity, attention problems, and aggression. Participants were families of 196 3-year-old children who took part in child and family assessments. Ethnicity was one of the most consistent predictors of discrepancies. African American mothers and fathers were more likely to rate their children's hyperactivity, attention problems, and aggression lower than teachers. In contrast, Latina mothers were more likely to rate their children as more hyperactive and inattentive than teachers. ADHD/ODD diagnoses, parental depression, number of children, and children's pre-academic skills were also predictive of discrepancies for some measures for some informants. These findings provide insight into factors that may contribute to informant discrepancies in ratings of preschool children. 相似文献

Summaries English Researchers from Japan, Romania and Sweden, together with the UNESCO Institute for Education (Hamburg), carried out a study of the functions of lifelong learning within education. Dozent Gestrelius reconstructs and comments on the Swedish part of this study. He delineates a comprehensive list of criteria which may be of paramount importance for curriculum renewal in science education. The author describes, in addition, the relations between some parts of Swedish curricula and the principles of lifelong learning (for example, self‐realization, self‐directed learning, creativity, flexibility). These are the results of empirical studies. 相似文献

During medium to large-scale emergency events such as fires or earthquakes, emergency response teams must be deployed to the location of the event in a timely fashion. Information gathered from 9-1-1 call makers is useful for this, but is not always accurate. In this paper, we show how the space–time permutation scan statistic can be used to detect the presence and location of such events by monitoring the overall spatiotemporal pattern of 9-1-1 emergency calls instead. In an analysis of collected 9-1-1 call data, top detected clusters were found to correlate with emergency events as reported on the news, showing the algorithm's usefulness for automatically estimating their location and temporal extent. We show how the detection procedure works in cases where the emergency event generates a small but statistically significant increase in the number of 9-1-1 calls, as well as cases where events must be detected against a large background activity of 9-1-1 calls. We discuss the possible adoption of the proposed algorithm within the next generation digital government framework. 相似文献

The purpose of this research is to explore the dynamics of cortisol regulation in the context of center-based child care by examining the impact of social context (large classroom vs. small group) and relationship quality with caregivers (conflict with mothers and teachers). We extend the research on children's physiologic stress system functioning in center-based child care by focusing on morning cortisol levels among young children living in poverty. While in high-quality center-based child care, children's cortisol levels decreased over the course of the morning—a result that contrasts with findings in previous research with middle-class children, for whom cortisol typically increased over the course of the day while attending center-based child care. Cortisol levels were further reduced when children were moved from a large classroom environment to a small group context. Relationship conflict with mothers and teachers moderated these effects. Children who had high conflict with their mother exhibited cortisol levels that remained higher (decreased less) over the course of the morning, and children who had high conflict with their teacher exhibited cortisol levels that remained higher (decreased less) in response to the small group context. These results indicate that high-quality child care has the potential to support reduced stress among children living in poverty, at least as indicated by adrenocortical activity. 相似文献

Economic and ideological motives underpin differing positions on the protection of intellectual property, with the strongest
divisions running between developed and less developed countries. Protection for intellectual property rests on international
treaties and agreements, regional arrangements, bilateral agreements, and unilateral actions. In recent years, nations that
have been notorioushavens for piracy have sought to bring their laws and enforcement more into line with international standards. 相似文献

A mail survey of 129 contact persons for polling organizationrevealed that 62 per cent of the firms from which responseswere received do not go back before 1980. Many respondents werethemselves newcomers, who had found their way into polling viapolitics and showed less commitment to the professional ethosthat meant so much to the pioneer pollsters. Newcomers, on theaverage, had fewer academic credentials and less training thaneither of two generations of more seasoned pollsters; more ofthem worked directly for politicians. The three generationsalso differed in the satisfactions sought from polling and onprofessional membership. Are we encountering a "new breed" ofpollsters? 相似文献

Die hier vorgestellte Studie untersucht den Zusammenhang zwischen unterrichtsbezogenen und handlungsleitenden Kognitionen
anhand einer Stichprobe von 20 deutschen und 18 schweizerischen Mathematiklehrpersonen. Die untersuchten unterrichtsbezogenen
überzeugungen fokussieren auf das konstruktivistische und das rezeptive Lehr-Lernverst?ndnis der Lehrpersonen, die spezifischen
Kognitionen auf das konkrete didaktische Handeln in einer Unterrichtseinheit zur Einführung in die Satzgruppe des Pythagoras.
In früheren Untersuchungen zeigte sich, dass sich deutsche Lehrpersonen konstruktivistischer als schweizerische Lehrkr?fte
einsch?tzten, ihren Unterricht aber eher als fragend-entwickelnd beschrieben. Ausgehend von diesem Befund werden in der Untersuchung
deutsche und schweizerische Lehrpersonen hinsichtlich ihrer überzeugungen und handlungsleitenden Kognitionen vergleichend
untersucht. In einem zweiten Schritt wird nach Zusammenh?ngen zwischen beiden Facetten professionellen Lehrerwissens gefragt.
Die Ergebnisse verweisen darauf, dass sich die deutschen Mathematiklehrpersonen in ihren überzeugungen st?rker als jene in
der Schweiz an einem konstruktivistischen Verst?ndnis von Lehr-Lernprozessen orientieren, dieses sich aber sowohl bei deutschen
als auch bei schweizerischen Lehrpersonen kaum in den handlungsleitenden Kognitionen widerspiegelt. Als Erkl?rung für diese
geringe Korrespondenz zwischen unterrichtsbezogenen überzeugungen und handlungsleitenden Kognitionen kommen u.a. belastende
Rahmenbedingungen und eine geringe Selbstwirksamkeit der Lehrpersonen in Frage. Daher werden in einem dritten Schritt Zusammenh?nge
zwischen unterrichtsbezogenen überzeugungen und handlungsleitenden Kognitionen unter Kontrolle belastender Rahmenbedingungen
und der Selbstwirksamkeit der Lehrpersonen untersucht. Dabei zeigen sich, allerdings in erster Linie nur bei schweizerischen
Lehrpersonen, einige erwartungskonforme systematische Zusammenh?nge zwischen konstruktivistischen überzeugungen und handlungsleitenden
Kognitionen. 相似文献
