Within-child associations between family income and externalizing and internalizing problems.

Within-child associations between family income and child externalizing and internalizing problems were examined using longitudinal data from the NICHD Study of Early Child Care and Youth Development (2004a, 2004b; N = 1,132). Variations in income effects were estimated as a function of whether families were poor, whether mothers were partnered, and the number of hours mothers and their partners were employed. On average, children had fewer externalizing problems during times when their families' incomes were relatively high than during times when their families' incomes were relatively low; the estimated benefits of increased income were greatest for children who were chronically poor. For both externalizing and internalizing problems, income was most strongly associated with problems when chronically poor children's mothers were partnered and employed.

Evaluation of Flexural Behavior and Serviceability Performance of Concrete Beams Reinforced with FRP Bars

Flexural behavior and serviceability performance of 24 full-scale concrete beams reinforced with carbon-, glass-, and aramid-fiber-reinforced-polymer (FRP) bars are investigated. The beams were 3,300?mm long with a rectangular cross section of 200?mm in width and 300?mm in depth. Sixteen beams were reinforced with carbon-FRP bars, four beams were reinforced with glass-FRP bars, two beams were reinforced with aramid-FRP bars, and two were reinforced with steel, serving as control specimens. Two types of FRP bars with different surface textures were considered: sand-coated bars and ribbed-deformed bars. The beams were tested to failure in four-point bending over a clear span of 2,750?mm. The test results are reported in terms of deflection, crack-width, strains in concrete and reinforcement, flexural capacity, and mode of failure. The experimental results were compared to the available design codes.

Reliability of Settlement Prediction—Case History

A geotextile-reinforced embankment was built over soft ground. Staged construction and vertical prefabricated drains were used to obtain strength gain via consolidation of the foundation material. Settlement and pore pressure were measured as a part of construction control. Settlement, differential settlement, and rate of consolidation were predicted by simple models. Uncertainties in the predictions were evaluated to assess the reliability of the predictions. The estimated errors were compared with the measured values, and major contributors to prediction errors were identified.     

Seismic Response of Interior RC Beam-Column Joints Upgraded with FRP Sheets. I: Experimental Study

In this paper, efficiency and effectiveness of carbon fiber-reinforced polymers (CFRP) in upgrading the shear strength and ductility of seismically deficient beam-column joints have been studied. For this purpose, four reinforced concrete interior beam-column sub-assemblages were constructed with nonoptimal design parameters (inadequate joint shear strength with no transverse reinforcement) representing preseismic code design construction practice of joints and encompassing the vast majority of existing beam-column connections. Out of these four, two specimens were used as baseline specimens (control specimens) and the other two were strengthened with CFRP sheets under two different schemes (strengthened specimens). In the first scheme, CFRP sheets were epoxy bonded to the joint, beams, and part of the column regions. In the second scheme, however, sheets were epoxy bonded to the joint region only but they were effectively prevented against any possible debonding through mechanical anchorages. All four subassemblages were subjected to cyclic lateral load histories so as to provide the equivalent of severe earthquake damage. Further, the damaged control specimens were repaired after filling the cracks through epoxy and wrapping them with CFRP sheets under the same two above-mentioned schemes. These repaired specimens were subjected to the similar cyclic lateral load history and their response histories were obtained. Hence, a total of six specimens were tested: two control; two strengthened; and two repaired. Response histories of control, repaired, and strengthened specimens were then compared. The results were compared through hysteretic loops, load-displacement envelopes, column profiles (maximum horizontal displacements of column along its height), joint shear distortion, ductility, and stiffness degradation. The comparison shows that CFRP sheets improve the shear resistance of the joint and increase its ductility. Results of two chosen schemes of strengthening were also compared and the importance of beam upgrading was highlighted.     

Amount of participation, coalescence, and profitability of decision making discussions.

51 groups of 255 ROTC cadets, varying in motivation and stratification, were examined in groups of 5 as they discussed the correct rankings of the familiarity of words. Measures of time talked, coalescence, and profit from discussion were collected on each of 10 problems solved by each group. Where members were equal in status, much participation was associates with increased decision accuracy, particularly when members were highly motivated; but the converse was true when groups were stratified, particularly where they were also unmotivated. Coalescence was associated with increased accuracy of decisions in moderately motivated groups, and in unstratified groups. Individual attempts to lead were more likely to be successful where members were motivated and where members varied in status. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Identification in group therapy.

"The Ss of this study were male and female adolescents (12-15 years of age) who were asked to volunteer to participate in groups that 'would discuss adolescent problems.' Those who volunteered were rated by their teachers on emotional adjustment. Ss rated as most poorly adjusted were eliminated from the study. Three therapy groups were organized, each composed of five boys and five girls, each in the charge of a different therapist. The members of the group were given a special questionnaire, designed to assess needs, and a group form of the Rorschach before therapy began. At the conclusion of therapy, all Ss again took the questionnaire… . The hypotheses that both rigidity and lability were inversely related to identification were tested by correlational methods. Results were positive in both instances." From Psyc Abstracts 36:01:1IG95B. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Time estimation in process-reactive schizophrenia.

Process and reactive schizophrenics, and reactive schizophrenics and normals were compared as to their responses on a perceptual time-estimation task. Null hypotheses being tested were that groups would not differ in variability or accuracy of response. Schizophrenic (45) and normal (15) subjects were selected from the male patient population and hospital employees, respectively, of a Veteran's Administration hospital. Schizophrenics selected for the study were classified by means of the Abbreviated Becker Elgin Scale. Subjects were individually administered a time-estimation task consisting of seven stimulus cards which were tachistoscopically presented, with exposure speeds at 10, 20, and 30 seconds for each card. Judgments of exposure times were converted into scores based upon ratios of estimated time to actual time. Scores (three) for each card were totaled. Groups were then compared on each of the stimulus cards by means of two-tailed t tests. In accuracy of estimation, process schizophrenics demonstrated significantly less accuracy than did reactives on four of the seven cards; no differences were shown between reactives and normals in accuracy of estimation.
