Maturation of auditory temporal integration and inhibition assessed with event-related potentials (ERPs)

Background: We examined development of auditory temporal integration and inhibition by assessing electrophysiological responses to tone pairs separated by interstimulus intervals (ISIs) of 25, 50, 100, 200, 400, and 800 ms in 28 children aged 7 to 9 years, and 15 adults.Results: In adults a distinct neural response was elicited to tones presented at ISIs of 25 ms or longer, whereas in children this was only seen in response to tones presented at ISIs above 100 ms. In adults, late N1 amplitude was larger for the second tone of the tone pair when separated by ISIs as short as 100 ms, consistent with the perceptual integration of successive stimuli within the temporal window of integration. In contrast, children showed enhanced negativity only when tone pairs were separated by ISIs of 200 ms. In children, the amplitude of the P1 component was attenuated at ISIs below 200 ms, consistent with a refractory process.Conclusions: These results indicate that adults integrate sequential auditory information into smaller temporal segments than children. These results suggest that there are marked maturational changes from childhood to adulthood in the perceptual processes underpinning the grouping of incoming auditory sensory information, and that electrophysiological measures provide a sensitive, non-invasive method allowing further examination of these changes

Resiliency in children at risk : a multivariate profile analysis of protective factors for children of adolescent mothers

The purpose of this longitudinal exploratory study was to investigate the protective processes that promote psychosocial competence in children who are at risk for maladaptive development. A resiliency model was developed and tested on a sample of 171 Anglo-American children (80 male and 91 female) of adolescent mothers living in two-parent families. Secondary data analysis was conducted on variables measured in Waves 1 and 2 of the National Survey of Children. In Phase One of the analysis, regression models that used multiple risk factors in the prediction of competency were applied to determine residual values for each individual. Phase Two used these residual values to categorize individuals into resilient and vulnerable groups for each competency criterion. Phase Three involved a multivariate profile analysis to test the moderating associations of eight protective factors for the resilient and vulnerable groups. All three phases of the analysis were conducted separately for external (action-oriented) competency and internal (thought-oriented) competency. Outcomes for external competency. Difficult temperament in childhood emerged as a strong risk predictor of external competency in adolescence. Results of the equal group effects test indicated support for overall group differences with higher resilient group means across the eight protective factors. However, multivariate analysis of the resilient and vulnerable groups also indicated a group by protective factor interaction. Univariate tests detected group differences for the following factors: (a) gender, (b) the child's aspirations for post-secondary education, (c) mother-child relations, and (d) academic progress

Effect of care environment on educational attainment among orphaned and separated children and adolescents in Western Kenya

Background: There are approximately 140 million orphaned and separated children (OSCA) around the world. In Kenya, many of these children live with extended family while others live in institutions. Despite evidence that orphans are less likely to be enrolled in school than non-orphans, there is little evidence regarding the role of care environment. This evidence is vital for designing programs and policies that promote access to education for orphans, which is not only their human right but also an important social determinant of health. The purpose of this study was to compare educational attainment among OSCA living in Charitable Children’s Institutions and family-based settings in Uasin Gishu County, Kenya. Methods: This study analyses follow up data from a cohort of OSCA living in 300 randomly selected households and 17 institutions. We used Poisson regression to estimate the effect of care environment on primary school completion among participants age ≥ 14 as well as full and partial secondary school completion among participants age ≥ 18. Risk ratios and 95% confidence intervals were estimated using a bootstrap method with 1000 replications. Results: The analysis included 1406 participants (495 from institutions, 911 from family-based settings). At baseline, 50% were female, the average age was 9.5 years, 54% were double orphans, and 3% were HIV-positive. At follow- up, 76% of participants age ≥ 14 had completed primary school and 32% of participants age ≥ 18 had completed secondary school. Children living in institutions were significantly more likely to complete primary school (aRR: 1.18, 95% CI: 1.10–1.28) and at least 1 year of secondary school (aRR: 1.28, 95% CI: 1.18–1.39) than children in family-based settings. Children living in institutions were less likely to have completed all 4 years secondary school (aRR: 0.79, 95% CI: 0.43–1.18) than children in family-based settings. Conclusion: Children living in institutional environments were more likely to complete primary school and some secondary school than children living in family-based care. Further support is needed for all orphans to improve primary and secondary school completion. Policies that require orphans to leave institution environments upon their eighteenth birthday may be preventing these youth from completing secondary school

Total Sitting Time and Sitting Pattern in Postmenopausal Women Differ by Hispanic Ethnicity and are Associated With Cardiometabolic Risk Biomarkers.

Background Sedentary behavior is pervasive, especially in older adults, and is associated with cardiometabolic disease and mortality. Relationships between cardiometabolic biomarkers and sitting time are unexplored in older women, as are possible ethnic differences. Methods and Results Ethnic differences in sitting behavior and associations with cardiometabolic risk were explored in overweight/obese postmenopausal women (n=518; mean±SD age 63±6 years; mean body mass index 31.4±4.8 kg/m2). Accelerometer data were processed using validated machine-learned algorithms to measure total daily sitting time and mean sitting bout duration (an indicator of sitting behavior pattern). Multivariable linear regression was used to compare sitting among Hispanic women (n=102) and non-Hispanic women (n=416) and tested associations with cardiometabolic risk biomarkers. Hispanic women sat, on average, 50.3 minutes less/day than non-Hispanic women (P<0.001) and had shorter (3.6 minutes less, P=0.02) mean sitting bout duration. Among all women, longer total sitting time was deleteriously associated with fasting insulin and triglyceride concentrations, insulin resistance, body mass index and waist circumference; longer mean sitting bout duration was deleteriously associated with fasting glucose and insulin concentrations, insulin resistance, body mass index and waist circumference. Exploratory interaction analysis showed that the association between mean sitting bout duration and fasting glucose concentration was significantly stronger among Hispanic women than non-Hispanic women (P-interaction=0.03). Conclusions Ethnic differences in 2 objectively measured parameters of sitting behavior, as well as detrimental associations between parameters and cardiometabolic biomarkers were observed in overweight/obese older women. The detrimental association between mean sitting bout duration and fasting glucose may be greater in Hispanic women than in non-Hispanic women. Corroboration in larger studies is warranted

In Defense of Preservation

In Defense of Preservation is the transcript of a presentation at the Gotham History Festival at the CUNY Graduate Center, October 6, 2001. The discussants argued that historic preservation is vital to New York City\u27s economic and cultural health, and countered arguments that preservation was elitist and hindered the city\u27s growth. Dorothy Minor discussed the legal basis for preservation and reviewed the Penn Central decision and other court cases. Anthony C. Wood discussed the history of historic preservation in New York. And Eric W. Allison presented the intersection of preservation with the liveable cities movement
