Child care quality: centers and home settings that serve poor families

The effects of center-based care on early development, outside of carefully controlled demonstration programs, appear to be positive yet often modest for children from low-income families. But little is known about variation in the quality of centers and preschools found among low-income neighborhoods. Evidence also remains scarce on the observed quality of home-based care, the settings that most children attend and into which large infusions of federal dollars are now directed. This paper reports on the observed quality of 166 centers and 187 nonparental home settings (including family child care homes and kith or kin providers) serving children in five cities situated in California, Connecticut, or Florida. Centers displayed higher mean quality as gauged by provider education and the intensity of structured learning activities, compared to home-based settings, but did not consistently display more positive child–provider interactions. Great variability among centers and home-based settings was observed, including between-city differences. Second, we found that contextual neighborhood attributes accounted for the quality of providers selected more strongly than family-level selection factors. Mothers with stronger verbal abilities (PPVT scores) did select higher quality centers; those employed longer hours each week relied on kith and kin providers with lower education levels. Interrelationships among different quality measures are detailed. The policy implications of such wide disparities in center and home-based care quality are discussed, including how states could more carefully strengthen regulatory or quality improvement efforts.     

School violence,school differences and school discourses

This article highlights one strand of a study which investigated the concept of the violence‐resilient school. In six inner‐city secondary schools, data on violent incidents in school and violent crime in the neighbourhood were gathered, and compared with school practices to minimise violence, accessed through interviews. Some degree of association between the patterns of behaviour and school practices was found: schools with a wider range of well‐connected practices seemed to have less difficult behaviour. Interviews also showed that the different schools had different organisational discourses for construing school violence, its possible causes and the possible solutions. Differences in practices are best understood in connection with differences in these discourses. Some of the features of school discourses are outlined, including their range, their core metaphor and their silences. The authors suggest that organisational discourse is an important concept in explaining school effects and school differences, and that improvement attempts could have clearer regard to this concept.

Level of deprivation does not affect degree of discounting in pigeons

Two experiments tested the effects of food deprivation on discounting in pigeons. An adjusting-amount procedure was used to estimate the subjective value of food at delays ranging from 1 to 24 s. Experiment 1 compared pigeons’ discounting of delayed food reinforcers at 75 %–80 % and 90 %–95 % of free-feeding weight. Experiment 2 compared discounting under 1- and 23-h food deprivation. In both experiments at both deprivation levels, discounting was well described by the hyperboloid discounting function. No systematic effect of level of deprivation on degree of discounting was observed in either experiment. This finding is consistent with the view that pigeons’ choices are controlled by the relative, rather than the absolute, value of reinforcers.     

Living–Learning Programs and First-Generation College Students’ Academic and Social Transition to College

This study examines the role of living–learning (L/L) programs in facilitating first-generation students’ perceived academic and social transition to college. Using a sample of 1,335 first-generation students from 33 4-year institutions who participated in the National Study of Living–Learning Programs during Spring 2004, the results of the study show that first-generation students in L/L programs reported a more successful academic and social transition to college than their first-generation counterparts living in a traditional residence hall setting. In addition, interactions with faculty members and using residence hall resources facilitated an easier academic transition for first-generation students in L/L programs, and supportive residence hall climates were related to an easier social transition. A preliminary interpretation of this study’s results is that structured activities, such as faculty interaction and residence hall programming, are more influential for this population than informal peer groups. An earlier version of this paper was presented at the 2005 Annual Meeting of the American Educational Research Association, Montreal, Canada.     

Children Persist Less When Adults Take Over

Children need to learn to persist through challenges, yet adults sometimes step in to solve problems for them. Here, we looked at how adult taking over related to children’s persistence. In an observational study (N = 34, ages 4–8), we found that parents who took over more often during a challenging puzzle task rated their children as dispositionally less persistent. To establish whether taking over can cause reduced persistence, we ran two preregistered experiments (N = 150, ages 4–5). Children assigned to a taking over condition persisted less on a subsequent task compared to those in a teaching or a baseline condition. Reframing the context did not ameliorate the negative impact of taking over. The results suggest that taking over impairs children’s persistence.     

Prenatal Risk and Infant Regulation: Indirect Pathways via Fetal Growth and Maternal Prenatal Stress and Anger

Pathways from maternal tobacco, marijuana, stress, and anger in pregnancy to infant reactivity and regulation (RR) at 9 months of infant age were examined in a low‐income, diverse sample beginning in the first trimester of pregnancy, with fetal growth and postnatal stress/anger as potential mediators, and infant sex as a moderator. Participants were 247 dyads (173 substance‐exposed infants). There were no direct effects of prenatal risk on RR and no moderation by sex. However, there were significant indirect effects on RR via poor fetal growth and higher postnatal anger. The study adds to the sparse literature on joint effects of tobacco and marijuana, and highlights the role of fetal growth and maternal anger as important pathways from prenatal risk to infant RR.     

Frequency,duration, and speed of wheel running of rats as a function of age and starvation

The purpose of this experiment was to determine whether age differences in amounts of wheel running of starved rats were due to the frequency of bursts of running, to the average duration of bursts, to speed, or to any combination of these parameters. The experiment was carried out according to a 3 by 2 by 2 mixed model design. The independent variables were age (67, 293, and 746 days old at the start of starvation), food deprivation (total starvation vs ad lib), and occasion of measurement (initial vs maximum activity). The dependent variables were number of wheel revolutions, number of bursts of activity, number of seconds of running per burst, and revolutions per second. The results indicated that acutely starved rats run more often, for longer periods, and at higher speeds than do sated rats, and that with increased age rats run less often, for a shorter time, and at slower speeds.     

School violence in the Canadian context: An overview and model for intervention

School violence and the incidence of violent crimesamong Canadian youth is seen to be increasing. Whilemore research is being conducted in the area ofschool violence little has previously been done toexamine psychopathology as a possible factorinfluencing violent student behavior. A recent studyconducted by Carter (1998) using the BehaviorAssessment System for Children and a structuredinterview showed a high incidence of psychopathologyamong violent junior high male students. Acomprehensive model for intervention is described inwhich several factors are presented. Implications ofcurrent research includes the need to developintervention strategies that are consistent withdiagnostic findings and the need for earlyidentification and intervention before behaviorpatterns become fixed in adolescence.
