The developmental trajectories of behavioral control and resiliency from early childhood to adolescence and their effects on early onset of substance use were examined. Behavioral control is the tendency to express or contain one's impulses and behaviors. Resiliency is the ability to adapt flexibly one's characteristic level of control in response to the environment. Study participants were 514 children of alcoholics and matched controls from a longitudinal community sample (Time 1 age in years: M =4.32, SD =0.89). Children with slower rates of increase in behavioral control were more likely to use alcohol and other drugs in adolescence. Children with higher initial levels of resiliency were less likely to begin using alcohol. 相似文献

We investigated risk factors in a population-based sample of alcoholic (father) and comparison families with 3-year-old sons. Alcoholic and comparison parents did not differ in socioeconomic status (SES), education, years married, family size, or cognitive functioning. Anti-social behavior and depression were significantly greater in alcoholic parents. High risk children were more impulsive than comparison children, but there were no differences in developmental age, IQ, or behavior problems. A higher percentage of high-risk children were rated in the extreme clinical range for behavior problems than were comparison children. For alcoholic families, mothers' ratings of their children's total behavior problems, externalizing behavior problems, and internalizing behavior problems were predicted by mothers' lifetime alcohol problems, current depression, and family SES. Father variables failed to predict children's behavior problems. Maternal variables were stronger predictors of their 3-year-old sons' problem behaviors than were paternal variables. 相似文献

This research was initiated to explore the effects of changing tuition rates on the open‐door policy of U.S. community junior colleges. Tuition trends in the two‐year colleges of 50 states were assessed using data gathered from the 1975 and 1980 editions of the AACJC Directory, 1980 Fact Book for Academic Administrators, and recently published journal articles. The relationship between tuition rates and enrollment levels in each state were analyzed. The analyses point to a trend of continuous increase in tuition rates for U.S. public two‐year colleges since 1951. Even though the percentage of increase in tuition for recent years has been higher for two‐year colleges than for four‐year colleges, there remains a substantial difference between the average annual tuition of the two types of institutions. There appears to be a negative correlation between tuition and enrollment at two‐year colleges for 1974‐1975 (—.27) and for 1979‐1980 (—.21). Based on these findings, it would appear that further increases in tuition might serve to close college doors for those not able to afford the rising costs of education. Suggestions are offered for internal and external actions to help maintain open access despite rising tuition costs. 相似文献

Regional growth of new knowledge in nanotechnology, as measured by counts of articles and patents in the open-access digital library NanoBank, is shown to be positively affected both by the size of existing regional stocks of recorded knowledge in all scientific fields, and the extent to which tacit knowledge in all fields flows between institutions of different organizational types. The level of federal funding has a large, robust impact on both publication and patenting. The data provide support for the cumulative advantage model of knowledge production, and for ongoing efforts to institutionalize channels through which cross-organizational collaboration may be achieved. 相似文献

This study examined the transactional, utterance-by-utterance dependencies in the syntactic complexity of teachers’ and children's talk during small-group conversations in preschool classrooms. The sample included 39 teachers and select children in their classroom, which targeted enrollment to children experiencing documentable risk factors. Patterns of sequential dependencies demonstrated a bi-directional interdependence in teachers’ and children's complex syntactic use, whereby both teachers and children appeared sensitive to each other's use of complex syntactic forms. Teachers’ use of complex syntax increased the likelihood that children's adjacent utterance would contain complex syntax; similarly, children's use of complex or simple syntax increased the likelihood that teachers’ adjacent utterance would mirror their syntactic level. Associations were small to moderately large in strength, but varied across individual classrooms. The findings point to complex, bi-directional relationships underlying the complexity of talk within the classroom language environment. 相似文献

The Role of Nonprofits in Educational Technology Innovation 总被引：1，自引：1，他引：0

For decades, nonprofit organizations have played a vital role in educational technology innovation. Sesame Street, online high schools, probeware for science and mathematics teaching and learning, and many other innovations now widely
used both in and outside schools were developed by nonprofits, including not only universities but also independent R&D organizations,
such as the Concord Consortium. Within the federal budget, there has been a decade-long trend to reduce both the size and
number of awards made specifically for innovation in educational technology. Small grants, including those for basic research,
are less likely to lead to transformative innovations in teaching and learning than larger, targeted awards for innovation.
At a time when digital tools continue to grow more useful and powerful, and when larger numbers of schools are using them
effectively, it is time for federal agencies to focus additional resources on educational technology innovation.

Research Findings: This study examined the association between interactive book reading quality and prekindergarten children’s gains in language and literacy skills over the course of an academic year for 96 teachers and 417 children across multiple locations in the United States. Two moderators were examined, namely, children’s initial skill level and teachers’ classroom organization during an interactive read-aloud session. In keeping with prior research, interactive book reading quality, measured by examination of teachers’ extratextual talk, was positively and significantly related to children’s development of both language and literacy skills. Interactive book reading quality was not significantly moderated by children’s initial skills, with the exception that interactive book reading quality appeared most beneficial to children’s print knowledge for children entering prekindergarten with relatively low skill. The unique contribution of this study is that the association between interactive book reading quality and children’s expressive vocabulary was dependent on an organized classroom during the book reading session. Practice or Policy: The quality of teachers’ talk during interactive book reading may matter for children’s vocabulary development only when reading sessions are characterized by relatively high classroom organization. Classroom organization should be an important consideration while planning for interactive book reading sessions. 相似文献

A review of the short-term effects of child sexual abuse 总被引：6，自引：2，他引：6
This is the first of a two-part report that critically evaluates empirical studies on the short- and long-term effects of child sexual abuse. With the exception of sexualized behavior, the majority of short-term effects noted in the literature are symptoms that characterize child clinical samples in general. Among adolescents, commonly reported sequelae include sexual dissatisfaction, promiscuity, homosexuality, and an increased risk for revictimization. Depression and suicidal ideation or behavior also appear to be more common among victims of sexual abuse compared to normal and psychiatric nonabused controls. Frequency and duration of abuse, abuse involving penetration, force, or violence, and a close relationship to the perpetrator appear to be the most harmful in terms of long-lasting effects on the child. The high prevalence of marital breakdown and psychopathology among parents of children who are sexually abused makes it difficult to determine the specific impact of sexual abuse over and above the effects of a disturbed home environment. Given the broad range of outcome among sexual abuse victims, as well as the methodological weaknesses present in many of the studies reviewed, it is not possible at this time to postulate the existence of a "post-sexual-abuse-syndrome" with a specific course or outcome. 相似文献

The Technology Enhanced Elementary and Middle School Science II project (TEEMSS), funded by the National Science Foundation,
produced 15 inquiry-based instructional science units for teaching in grades 3–8. Each unit uses computers and probeware to
support students’ investigations of real-world phenomena using probes (e.g., for temperature or pressure) or, in one case,
virtual environments based on mathematical models. TEEMSS units were used in more than 100 classrooms by over 60 teachers
and thousands of students. This paper reports on cases in which groups of teachers taught science topics without TEEMSS materials
in school year 2004–2005 and then the same teachers taught those topics using TEEMSS materials in 2005–2006. There are eight
TEEMSS units for which such comparison data are available. Students showed significant learning gains for all eight. In four
cases (sound and electricity, both for grades 3–4; temperature, grades 5–6; and motion, grades 7–8) there were significant
differences in science learning favoring the students who used the TEEMSS materials. The effect sizes are 0.58, 0.94, 1.54,
and 0.49, respectively. For the other four units there were no significant differences in science learning between TEEMSS
and non-TEEMSS students. We discuss the implications of these results for science education. 相似文献

ABSTRACTContract cheating occurs when a student outsources their assessment to a third party, regardless of the third party’s relationship with the student, or whether money is exchanged. In higher education, there is a widespread belief that assessment design is a solution to the problem of contract cheating and that authentic assessment tasks are particularly effective. This research analysed two datasets – 221 assignment orders placed on academic custom writing websites and 198 assessment tasks in which contract cheating was detected – to investigate if authentic assessment can assure academic integrity. The authenticity of assessments was determined using five factors derived from the literature: frequency, fidelity, complexity, real-world impact and feed forward. Our analysis found that assessment tasks with no, some, or all of the five authenticity factors are routinely outsourced by students. 相似文献
