Depression and Anxiety in the Postnatal Period: An Examination of Infants’ Home Language Environment,Vocalizations, and Expressive Language Abilities

This longitudinal study investigated the effects of maternal emotional health concerns, on infants’ home language environment, vocalization quantity, and expressive language skills. Mothers and their infants (at 6 and 12 months; 21 mothers with depression and or anxiety and 21 controls) provided day-long home-language recordings. Compared with controls, risk group recordings contained fewer mother–infant conversational turns and infant vocalizations, but daily number of adult word counts showed no group difference. Furthermore, conversational turns and infant vocalizations were stronger predictors of infants’ 18-month vocabulary size than depression and anxiety measures. However, anxiety levels moderated the effect of conversational turns on vocabulary size. These results suggest that variability in mothers’ emotional health influences infants’ language environment and later language ability.  相似文献   

Creating teacher capacity in Early Childhood Education and Care institutions implementing an authoritative adult style     

Heidi Omdal 《Journal of Educational Change》2018,19(1):103-129

The being together intervention intends to raise teacher capacity in Norwegian Early Childhood Education and Care (ECEC) institutions and promote social and emotional development in preschoolers by implementing an authoritative (warm and predictable) adult style in the institution. An authoritative adult balances between building up high quality interactions with children, while at the same time having a predictable structure with clear norms and social expectations in the learning environment. The purpose of this study was to investigate what helped the ECEC institutions to successfully implement the program principles and core components, and what were the challenges. The staff groups of seven Norwegian ECEC institutions in different municipalities who took part in the innovation were interviewed at the beginning and before the end of the first year of implementation. Data analysis identified five success criteria in the implementation process; strong commitment to the authoritative adult style, strong focus on the implementation process, advanced support systems, highly involved leaders, and a collective orientation. These elements resulted in a shared vision and an academically grounded practice in the ECEC institutions. Staff members without formal professional training and a lack of written documentation in the ECEC institutions should be given more consideration in further improvement of the capacity building.  相似文献

Approaches to digital methods in studies of digital religion     

Ruth Tsuria  Aya Yadlin-Segal  Alessandra Vitullo  Heidi A. Campbell 《The Communication Review》2017,20(2):73-97

This article reviews digital methodologies in the context of digital religion. We offer a tripod model for approaching digital methods: (a) defining research within digital environments, (b) the utilization of digital tools, and (c) applying unique digital frames. Through a critical review of multiple research projects, we explore three dominant research methods employed within the study of digital religion, namely, the use of textual analysis, interviews, and ethnography. Thus, we highlight the opportunities and challenges of using digital methods.  相似文献   

Scientific teams and institutional collaborations: Evidence from U.S. universities, 1981-1999     

James D. Adams  Grant C. Black  Paula E. Stephan 《Research Policy》2005,34(3):259-285

This paper explores recent trends in the size of scientific teams and in institutional collaborations. The data derive from 2.4 million scientific papers written in 110 top U.S. research universities over the period 1981-1999. The top 110 account for a large share of published basic research conducted in the U.S. during this time.We measure team size by the number of authors on a scientific paper. Using this measure we find that team size increases by 50% over the 19-year period. We supplement team size with measures of domestic and foreign institutional collaborations, which capture the geographic dispersion of team workers. The time series evidence suggests that the trend towards more geographically dispersed scientific teams accelerates beginning with papers published at the start of the 1990s. This acceleration suggests a sharp decline in the cost of collaboration. Our hypothesis is that the decline is due to the deployment of the National Science Foundation's NSFNET and its connection to networks in Europe and Japan after 1987.Using a panel of top university departments we also find that private universities and departments whose scientists have earned prestigious awards participate in larger teams, as do departments that have larger amounts of federal funding. Placement of former graduate students is a key determinant of institutional collaborations, especially collaborations with firms and with foreign scientific institutions. Finally, the evidence suggests that scientific output and influence increase with team size and that influence rises along with institutional collaborations. Since increasing team size implies an increase in the division of labor, these results suggest that scientific productivity increases with the scientific division of labor.  相似文献   

Hostile attribution of intent and aggressive behavior: a meta-analysis     

Orobio de Castro B  Veerman JW  Koops W  Bosch JD  Monshouwer HJ 《Child development》2002,73(3):916-934

A meta-analytic review was conducted to explain divergent findings on the relation between children's aggressive behavior and hostile attribution of intent to peers. Forty-one studies with 6,017 participants were included in the analysis. Ten studies concerned representative samples from the general population, 24 studies compared nonaggressive to extremely aggressive nonreferred samples, and 7 studies compared nonreferred samples with children referred for aggressive behavior problems. A robust significant association between hostile attribution of intent and aggressive behavior was found. Effect sizes differed considerably between studies. Larger effects were associated with more severe aggressive behavior, rejection by peers as one of the selection criteria, inclusion of 8- to-12-year-old participants, and absence of control for intelligence. Video and picture presentation of stimuli were associated with smaller effect sizes than was audio presentation. Staging of actual social interactions was associated with the largest effects. The importance of understanding moderators of effect size for theory development is stressed.  相似文献
