Early Adverse Experiences and Repeated Wheezing From 6 to 30 Months of Age: Investigating the Roles of Hypothalamic–Pituitary–Adrenal Axis Functioning,Child Sex,and Caregiving Sensitivity

This study examined associations among early adversity, diurnal cortisol, child sex, and caregiver sensitivity at age 6 months in relation to wheezing in children (47% male) followed to 30 months. Analyses included 676 mother-child dyads, 393 of whom completed an observational caregiver sensitivity measure. Participants were primarily ethnic minorities (42.7% Black, 25.4% Hispanic); 22.1% of children had ≥ 1 wheezing episode. Higher adversity was associated with increased wheeze frequency and blunted diurnal cortisol slope. The indirect effect of adversity on wheezing through cortisol slope was significant for females, but not males. Higher caregiver sensitivity was protective against wheezing for males, but not females, with high cortisol. Findings suggest complex associations among adversity, cortisol, child sex, and caregiver sensitivity in predicting wheezing.     

Theoretical Value Belief, Cognitive Ability, and Personality as Predictors of Student Performance in Object-Oriented Programming Environments

The research described in this article reports the results of a study designed to evaluate the relationship among object‐oriented (OO) computer programming task performance and a student's (1) theoretical value belief, (2) cognitive ability, and (3) personality. The results of this study do not support the assertion that cognitive ability is a main determinant of performance. Rather, the findings suggest that characteristics of an individual nature have more effect on a student's performance. This supports our belief advanced herein that theoretical value belief and personality are significant predictors of computer programming performance in OO environments. From the findings of this study, we assert that academicians who must teach OO computer programming consider these factors when developing course materials or student assistance programs.     

The Connection Between Teaching Methods and Attribution Errors

We collected data at a large, very selective public university on what math and science instructors felt was the biggest barrier to their students’ learning. We also determined the extent of each instructor’s use of research-based effective teaching methods. Instructors using fewer effective methods were more likely to say the greatest barrier to student learning was the internal deficiencies of the students (the “fundamental attribution error”). They listed deficiencies such as poor preparation and work ethic. In total, 37 % of the instructor attributions were to student deficiencies, but this fraction varied dramatically between departments.     

Is the Door-in-the-Face a Concession?

The Door-in-the-Face (DITF) sequential message strategy was investigated in a three-study analysis of existing experimental findings. The current study predicted there would be a positive relationship between concession size and compliance rates in DITF studies. Study 1 included 25 comparisons where size of concession was quantifiable as measured by percentage reduction from initial to target request in the DITF condition. Study 2 data relied on a panel of undergraduate students to provide an index of concession size in 12 additional observations. A third study validated the panel procedure of rating concession size and also provided 9 additional independent observations from the pool of published studies on DITF. Results from each study indicated a positive relationship between concession size and effect size (r = 0.35, 0.55, 0.68, respectively). Study findings provide support for reciprocal concessions explanation for DITF effects.     

U.S. and Israeli young women’s future perceptions

The current study investigated the content of future perceptions among 47 U.S. women and 48 Israeli women. Thematic analysis was used to explore participants’ qualitative responses. Women’s responses covered a wide range of topics, and were categorized into ten key themes: (a) work, (b) family/relationships, (c) property, (d) residence, (e) education, (f) general quality of life, (g) leisure, (h) pro-social activities, (i) multiple role management, and (j) religion. Results demonstrated the role of nationality in the process of exploration and future perceptions. Implications for research and practice are discussed.     

Characteristics of Early Care and Education Collaboration Associated with Success

ABSTRACT

Research Findings: In this non-experimental study, the research team analyzed data from a randomly selected sample of child care programs in Maryland and Vermont to understand what characteristics contribute to collaboration success. The team also examined the relationship between collaboration success and measures of child care program quality. We found positive correlations between collaboration success – defined as programs’ use of collaborative strategies, structural indicators of quality, and QRIS ratings – and programs’ collaboration administration and collaboration relationships. In addition, programs that used more collaboration strategies had higher ratings on the state’s Quality Rating and Improvement System (QRIS). Policy or Practice: Policies designed to encourage early childhood collaborations should support strong administrative processes among collaborators and provide specific guidance on building strong relationships among child care and early education administrators. Future research is needed to determine the causes of the associations. Research should focus on how policies can broaden the reach of federal and state programs that promote collaboration to include programs that have lower QRIS ratings or programs that opt out of these state systems.     

Profiles of disruptive behavior across early childhood: contributions of frustration reactivity, physiological regulation, and maternal behavior

Disruptive behavior, including aggression, defiance, and temper tantrums, typically peaks in early toddlerhood and decreases by school entry; however, some children do not show this normative decline. The current study examined disruptive behavior in 318 boys and girls at 2, 4, and 5 years of age and frustration reactivity, physiological regulation, and maternal behavior in the laboratory at 2 years of age. A latent profile analysis resulted in 4 longitudinal profiles of disruptive behavior, which were differentiated by interactions between reactivity, regulation, and maternal behavior. A high profile was associated with high reactivity combined with high maternal control or low regulation combined with low maternal control. Results are discussed from a developmental psychopathology perspective.     

Cortisol in Neonatal Mother's Milk Predicts Later Infant Social and Cognitive Functioning in Rhesus Monkeys

Milk provides not only the building blocks for somatic development but also the hormonal signals that contribute to the biopsychological organization of the infant. Among mammals, glucocorticoids (GCs) in mother's milk have been associated with infant temperament. This study extended prior work to investigate rhesus monkey (Macaca mulatta) mother–infant dyads (N = 34) from birth through 8 months postpartum. Regression analysis revealed that cortisol concentrations in milk during the neonatal period predicted impulsivity on a cognitive task, but not global social behaviors, months later. During this time period, sex‐differentiated social behavior emerged. For female infants, milk cortisol concentrations predicted total frequency of play. Collectively, these findings support and extend the “lactational programming” hypothesis on the impact of maternal‐origin hormones ingested via milk.     

School–University–Community Pathways to Higher Education: Teacher Perceptions,School Culture and Partnership Building

This article provides a snapshot in time of teacher perceptions, school culture, and partnership building. We delineate how teachers perceive our partnership’s purpose and its role in transforming school culture. Second, we describe how teachers express the life expectations they have and the possibilities they hope for their students and the families involved with the partnership. Finally, we outline our thoughts on moving forward with building partnership, continuing to transform school culture, and collaborating with teachers. In conclusion, we discuss the role that partnership building can have on creating pathways to higher education for students in communities of color.
