This study examined the longitudinal effects of 2 first-grade universal preventive interventions on academic outcomes (e.g., achievement, special education service use, graduation, postsecondary education) through age 19 in a sample of 678 urban, primarily African American children. The classroom-centered intervention combined the Good Behavior Game (H. H. Barrish, Saunders, & Wolfe, 1969) with an enhanced academic curriculum, whereas a second intervention, the Family–School Partnership, focused on promoting parental involvement in educational activities and bolstering parents’ behavior management strategies. Both programs aimed to address the proximal targets of aggressive behavior and poor academic achievement. Although the effects varied by gender, the classroom-centered intervention was associated with higher scores on standardized achievement tests, greater odds of high school graduation and college attendance, and reduced odds of special education service use. The intervention effects of the Family–School Partnership were in the expected direction; however, only 1 effect reached statistical significance. The findings of this randomized controlled trial illustrate the long-term educational impact of preventive interventions in early elementary school.

Cast-mono crystalline silicon wafers contain crystallographic defects, which can severely impact the electrical performance of solar cells. This paper demonstrates that applying hydrogenation processes at moderate temperatures to finished screen print cells can passivate dislocation clusters within the cast-mono crystalline silicon wafers far better than the hydrogenation received during standard commercial firing conditions. Efficiency enhancements of up to 2% absolute are demonstrated on wafers with high dislocation densities. The impact of illumination to manipulate the charge state of hydrogen during annealing is investigated and found to not be significant on the wafers used in this study. This finding is contrary to a previous study on similar wafers that concluded increased H– or H0 from laser illumination was responsible for the further passivation of positively charged dangling bonds within the dislocation clusters. 相似文献

The heterocoupling between 2-nitrobenzoic and 2,6-dimethoxybenzoic acids was studied. It was demonstrated that the [PdCl2/Cu(OH)2:0.2/0.75 equiv.] catalytic system can catalyze this reaction with significant yield. Further optimizations (i.e.: sources and loadings of copper and palladium salts, base) allowed to isolate the biaryl in 70 % yield. A catalytic cycle that accounts for the observed results is proposed. While the bi-metal catalyst has shown high yields with some substrates, it is only able to catalyze the decarboxylative coupling in high yield for some of the substrates studied. 相似文献

The textural characteristics of three commercial activated carbons, Filtrasorb 400 (F400), Industrial React High Affinity
and Picabiol, commonly used in water treatment, are reinvestigated. Nitrogen physisorption isotherms are determined in the
range P/P
0 = [4 × 10−7–0.998] and processed using BET, αS (Sing), Dubinin–Radushkevich and Density Functional Theory methods. In addition, fractal dimensions are determined by the
Frenkel–Halsey–Hill procedure. Since F400 is often considered as a reference material in studies on the adsorption of solutes
in aqueous solutions, a review of the textural characteristics of this carbon is carried out. The results obtained in this
work using the different methods are consistent and a critical crossed comparison of these results allows discussing the limitations
of the methods used. In particular, the impact of the P/P
0 range considered on S
BET value is examined. In addition, the accuracy of the BET specific surface area is assessed in the light of information from
recent literature. 相似文献

Background
Decreased bone mineral density and osteoporosis in postmenopausal women represents a growing source of physical limitations and financial concerns in our aging population. While appropriate medical treatments such as bisphosphonate drugs and hormone replacement therapy exist, they are associated with serious side effects such as osteonecrosis of the jaw or increased cardiovascular risk. In addition to calcium and vitamin D supplementation, previous studies have demonstrated a beneficial effect of dietary silicon on bone health. This study evaluated the absorption of silicon from bottled artesian aquifer water and its effect on markers of bone metabolism. 相似文献127.

Physicochemical Properties and Eating Qualities of Milled Rice from Different Korean Elite Rice Varieties 总被引:1,自引:0,他引:1
Mi-Young Kang Catherine W. Rico Chae-Eun Kim 《International Journal of Food Properties》2013,16(3):640-653
Physicochemical properties and palatability of rice from six elite varieties in Korea (Chucheongbyeo, Saechucheongbyeo, Mihyangbyeo, Hitomebore, Nampyeongbyeo, and Ilpumbyeo) were analyzed. All samples, which contained 17–18 g/100 g rice starch amylose, belong to low-amylose rice group. Hitomebore variety showed abundant amount of essential amino acids, highest palatability score (82.9), and lowest mineral content. The rice samples contained relatively similar concentrations of saturated (21–24 g/100 g rice) and unsaturated (75–78 g/100 g rice) fatty acids. Mihyangbyeo variety exhibited the highest amount of protein (8.10 g/100 g rice), sugar content, and pasting temperature (82.75°C) and time (3.78 min), but lowest viscosity values. Ribose, rhamnose, and potassium were found to have negative correlations with palatability and breakdown viscosity, indicating that gelatinization characteristics could also be used in evaluating the eating quality of rice. Results of this study could assist plant breeders in developing rice varieties with improved genetic traits and high eating quality. 相似文献

This study examined the relationship of early alliance ruptures and their resolution to process and outcome in a sample of 128 patients randomly assigned to 1 of 3 time-limited psychotherapies for personality disorders: cognitive–behavioral therapy, brief relational therapy, or short-term dynamic psychotherapy. Rupture intensity and resolution were assessed by patient- and therapist-report after each of the first 6 sessions. Results indicated that lower rupture intensity and higher rupture resolution were associated with better ratings of the alliance and session quality. Lower rupture intensity also predicted good outcome on measures of interpersonal functioning, while higher rupture resolution predicted better retention. Patients reported fewer ruptures than did therapists. In addition, fewer ruptures were reported in cognitive–behavioral therapy than in the other treatments.
