Caught in the triangle of mobility: social,residential and pupil mobility

This article examines the school choices of families who have recently experienced downward mobility during the economic crisis in Spain. Based on semi-structured interviews we analyse the educational strategies of the families in a Bourdieusian framework, focusing on how they cope with the loss of their perceived social status. Prior to the crisis, these families of working-class origin improved their social position as a result of their success in economic capital accumulation with a humble increase in social and cultural capital. Our research suggests that the concerns of families confronted with downward social mobility are manifested in tensions related to their school choice in terms of their strategies of resistance and negotiation with regards to the ownership, social composition and corresponding perceived quality of the school. School can symbolically represent the last resort, an indispensable investment in one’s own future and that of the next generation.     

The Paradox of HBCU Graduation Rates

This paper examines the propensity of African American students to graduate from Historically Black Colleges and Universities (HBCUs). Using IPEDS data from 2004 to 2016, we take care in developing a control group of institutions from which to compare HBCU success. Results suggest that despite accepting more students who are at risk of not graduating, HBCUs have a higher graduation rate for African American students than their peers. We then show that gender nor major choice help explain this persistent difference.

     

Child-Directed Speech Is Infrequent in a Forager-Farmer Population: A Time Allocation Study

This article provides an estimation of how frequently, and from whom, children aged 0–11 years (Ns between 9 and 24) receive one-on-one verbal input among Tsimane forager-horticulturalists of lowland Bolivia. Analyses of systematic daytime behavioral observations reveal < 1 min per daylight hour is spent talking to children younger than 4 years of age, which is 4 times less than estimates for others present at the same time and place. Adults provide a majority of the input at 0–3 years of age but not afterward. When integrated with previous work, these results reveal large cross-cultural variation in the linguistic experiences provided to young children. Consideration of more diverse human populations is necessary to build generalizable theories of language acquisition.     

On modeling and analyzing multi-agent systems using n-calculus

Dynamic architecture of multi-agent systems （MAS） is important for critical systems. As the existing formal specifications of MAS cannot describe its dynamic architecture, a formal approach using n-calculus is presented, which is suited for the describing and analyzing of concurrent MAS with dynamic topology, n-calculus describes the belief-desireintention （BDI） model that represents agent＇s mental states and provides many useful facilities to analyze MAS model such as deadlock, behavior equivalence, and model checking. To illustrate the favorable representation capability of n-calculus, an example of dynamic multi-agent systems in e-commerce is provided. Finally, by using an existing n-calculus supporting tool, MAS model and some key behaviors properties are analyzed and verified.     

Parent and Child References to Letters During Alphabet Book Reading: Relations to Child Age and Letter Name Knowledge

Research Findings: The purpose of this study was to examine the frequency of extratextual references to letters made by parents and preschoolers during shared reading of an alphabet book. The frequency of letter references was also examined in relation to child age and knowledge of letter names. Participants consisted of 44 preschoolers and their primary caregivers. Videotaped book-reading data were transcribed verbatim and coded for their inclusion of 14 types of letter references (e.g., naming requests, labels, repetitions). Significant findings included the following: Parent labels were significantly correlated with child age; and child knowledge of letter names was significantly correlated with parent naming requests, corrections, and repetitions, and child answers and initiations. Practice or Policy: Findings are discussed in reference to the literature regarding parental sensitivity to child age and knowledge in educational interactions with their child.     

Measuring Teacher–Child Relationships in the Greek Kindergarten Setting: A Validity Study of the Student–Teacher Relationship Scale–Short Form

Research Findings: The present study was designed to examine the factorial validity of the Student–Teacher Relationship Scale–Short Form (STRS-SF; R. C. Pianta, 2001 Hamre, B. K. and Pianta, R. C. 2001. Early teacher-child relationships and the trajectory of children's school outcomes through eighth grade.. Child Development, 72: 625–638. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and its invariance across gender in the Greek educational context. The STRS-SF comprises 15 items that measure 2 dimensions of teacher–child relationships: Closeness and Conflict. Fifty-six kindergarten teachers completed the STRS-SF about their students (n = 336). A 2-factor model with correlated latent factors was postulated and tested. Confirmatory factor analysis procedures showed marginal fit to the data (comparative fit index [CFI] = .902, root mean square error of approximation [RMSEA] = .066). The fit of the model was further improved by adding 2 error covariances (CFI = .931, RMSEA = .056). Cronbach's alpha coefficient showed adequate internal consistency for Closeness (α = .72) and Conflict (α = .82). In addition, there was a moderate negative association between the 2 subscales (r = ?.38). Examination of STRS-SF invariance showed that it was manifested in the same way across gender. Practice or Policy: The findings of the present study, which was conducted in a cultural context different from the one in which the STRS-SF was developed, seem to support the instrument's factorial validity and equivalence across gender.     

Two Are Better Than One: The Joint Influence of Maternal Preparedness for Parenting and Children's Self-Esteem on Academic Achievement and Adjustment

Research Findings: This study investigated the joint influence of maternal cognitive readiness to parent and children's self-esteem on children's academic achievement and behavioral adjustment in the classroom at age 10. Participants were 153 adolescent mothers and their firstborn children. Findings indicated that low levels of prenatal maternal cognitive readiness to parent were associated with impairments in children's achievement and adjustment at age 10, regardless of the children's level of self-esteem. Among dyads in which mothers were more cognitively prepared for the parenting role, however, children with higher self-esteem showed notably better achievement and adjustment compared to those with lower self-esteem. These results illustrate the joint influence of mothers' preparedness for parenting and children's self-esteem on the school performance of children who are generally considered to be at high risk for impairments in achievement and adjustment. Practice or Policy: Findings are discussed in terms of the enduring impact of cognitive readiness to parent and self-esteem on the academic achievement and behavioral adjustment of at-risk children, with a focus on implications for intervention and prevention based on the specific findings from this study.     

Home Literacy Exposure and Early Language and Literacy Skills in Children Who Struggle With Behavior and Attention Problems

Research Findings: This study investigated the relationships between behavior and attention problems and early language and literacy outcomes for 4-year-olds who experienced varied early home literacy environments. Participants were 1,364 children enrolled in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Attention problems and early home literacy exposure both significantly predicted language and literacy outcomes when relevant covariates were controlled. There was also a significant interaction between behavior and attention problems and early home literacy exposure in predicting expressive language abilities. Specifically, early home literacy exposure was related to more advanced expressive language achievement for children with behavior problems. In contrast, children with attention problems performed below their peers on expressive language measures even when they received comparable early home literacy exposure. Practice or Policy: These findings suggest the need for further research on the differential role of early home literacy exposure on the development of early language and literacy skills in children with behavior and attention problems.
