In order to explore the possible confounding effects of age, race, sex, and socioeconomic status on developmental outcomes of prenatal cocaine exposure, two matched samples of preschoolers (20 children with cocaine/polydrug in utero exposure and 20 children with no prenatal drug exposure) were compared on the Stanford-Binet: 4th ed. (S-B: 4th ed.), Social Skills Rating System, Vineland Adaptive Behavior Scale—Survey Form, Preschool Language Scale: 3rd ed. (PLS: 3rd ed.), and the Child Behavior Checklist. None of the 40 children had attended or were currently enrolled in preschool programs. Both groups had scores approximately one standard deviation below the expected mean in social skills, auditory comprehension, and expressive language. Likewise, externalizing behavior difficulties were approximately one standard deviation above the mean for both groups. Results suggest in utero drug exposure had no independent impact on cognitive, social, language, and behavioral developmental outcomes when the confounding variables of age, ethnicity, gender, and SES were controlled. © 1997 John Wiley & Sons, Inc. 相似文献

While issues of recruiting older persons in clinical trials are well known, efficacious strategies in the recruitment process in applied social research are less explored. As more research becomes community-based, it is useful to see, if effective clinical-trial recruitment strategies can be applied to social and applied research studies. The goal of this article is to examine clinical recruitment strategies used with older adults (e.g. print and electronic advertising, referrals, and community-partnered approaches) in applied social research studies and to illustrate issues arising from the use of each recruitment approach with older adults in real-life settings. Experiences from four community-based, social research studies are included to show how some of the most successful clinical recruitment strategies fare in social gerontological studies. Specific guidelines are provided about how recruitment strategies can aid in future study planning and improved recruitment of older participants in social research. 相似文献

Through reflection on a longitudinal teaching, devising, and directing experience in a regional prison, as well as subsequent opportunities for collaboration with formerly incarcerated students, this article posits improvisation as a powerful vehicle for inclusivity, pluralism, and humanistic exchange in applied arts settings. 相似文献

Reported are the results of a multiyear study in which reading comprehension and writing were integrated within an in-depth science instructional model (Science IDEAS) in daily 1.5 to 2 h daily lessons on a schoolwide basis in grades 3–4–5. Multilevel (HLM7) achievement findings showed the experimental intervention resulted in significant and consistent direct effects in grades 3–4–5 and complementary transfer effects in grades 6–7 on both ITBS Science (+1.08 Grade Equivalent Units [GE]) and ITBS Reading (+.57 GE). Discussed are implications of the findings and related research for changing grade K-5 curriculum policy to allocate increased instructional time for integrated science instruction. 相似文献

Studies on serum arginase have shown that it is having the least unexplained variation and its activity is closely related with the severity of jaundice. Arginase is thus stable, consistent, efficient, specific and sensitive to changes. It is a better indicator of hepatocellular damage. 相似文献

Developmentalists are often interested in understanding change processes, and growth models are the most common analytic tool for examining such processes. Nonlinear growth curves are especially valuable to developmentalists because the defining characteristics of the growth process such as initial levels, rates of change during growth spurts, and asymptotic levels can be estimated. A variety of growth models are described beginning with the linear growth model and moving to nonlinear models of varying complexity. A detailed discussion of nonlinear models is provided, highlighting the added insights into complex developmental processes associated with their use. A collection of growth models are fit to repeated measures of height from participants of the Berkeley Growth and Guidance Studies from early childhood through adulthood. 相似文献

This research focused on the career decision and planning needs of a unique group of migrants: international students who
are completing their studies as temporary immigrants and who are embarking on the career journey of employment and permanent
immigration. A semi-structured interview employing a Critical Incident Technique was used to assess the career influences
of 19 undergraduate and graduate international students at a Canadian university. Data were analyzed using a constant comparison
method and critical incident protocol. Students were motivated to remain in Canada due to enhanced job opportunities and high
standard of living. Barriers to migration included the fear of not securing employment and cultural and linguistic barriers.
International students would like to see campus and career services specified to the needs of international and graduate students
to help them realize their goal of pursuing employment as the key to permanent immigration. 相似文献

In this study, carbon fiber electrodes were incorporated within a hollow microneedle array, which was fabricated using a digital micromirror device-based stereolithography instrument. Cell proliferation on the acrylate-based polymer used in microneedle fabrication was examined with human dermal fibroblasts and neonatal human epidermal keratinocytes. Studies involving full-thickness cadaveric porcine skin and trypan blue dye demonstrated that the hollow microneedles remained intact after puncturing the outermost layer of cadaveric porcine skin. The carbon fibers underwent chemical modification in order to enable detection of hydrogen peroxide and ascorbic acid; electrochemical measurements were demonstrated using integrated electrode-hollow microneedle devices. 相似文献
