How do parents learn about adolescents' experiences? Implications for parental knowledge and adolescent risky behavior

Cluster analysis was used to identify groups defined by the patterning of fathers' and mothers' sources of knowledge about adolescents' experiences in a sample of 179 families with adolescents (M = 16.5 years). Three clusters emerged for fathers (relational, relies on spouse, relies on others) and mothers (relational, questioners, relies on others). Cluster membership was associated with socioeconomic status, work hours, personal characteristics, and parent-child relationship quality. Longitudinal path analyses revealed that knowledge sources predicted levels of knowledge, which in turn predicted risky behavior 1 year later, indirect paths that were more consistent for fathers than for mothers. Although direct associations between sources of knowledge and subsequent risky behavior were scant, when fathers relied on spouses, youth engaged in less risky behavior.     

Fostering an Interest in Science in a Typically Underrepresented Population

ABSTRACT:  This "case study" details how food science was introduced into the classrooms of a typically underrepresented population. James Sarakatsannis, an 8th grade physical science teacher, was planning a unit that would use fast food to teach science to his classes, when he came across the Institute of Food Technologists (IFT) website and a wealth of information available to teachers. Along with the valuable materials James found on the website to teach food science, he also found the "Find a Food Scientist" tool and invited 3 local food scientists into his classroom at John Philip Sousa Middle School in the inner city of Washington, D.C., where many of his students represent a typically underrepresented population in the field of food science. Food was a common medium that all of his students were familiar with and had an interest in, and it turned out to be a great tool to discuss various physical science topics in the classroom. The local food scientist visits were an excellent supplement to the topics he was already covering with the students in class. Many students developed a greater interest in science in general after the unit on food science. The unit also may have planted the seed for an education or career in food science somewhere down the line for the 70 13- to 16-year-old students in James's 2 8th grade physical science classes.     

Modification of a mother's verbal abuse

In this study an abusive parent was instructed in techniques of behavior modification. It was hypothesized that the parent-child interactions would improve as the mother, Mrs. X, began modifying her daughter Jan's behavior.An A-B - A-B reversal design was implemented. Baseline data was collected to determine the frequency with which Jan interrupted Mrs. X. During the treatment phase, Mrs. X was to ignore Jan's interruptions and positively reinforce Jan when she spoke to Mrs. X without interrupting. However, Mrs. X did not apply the treatment consistently and the frequency of Jan's interruptions did not change significantly. Thus a return to baseline and reimplementation of the treatment was not necessary.In order to ascertain whether the parent-child interactions chanqed, two thirty-minute tapes of the baseline sessions were made and two thirty-minute tapes of the treatment sessions were made. The tapes were transcribed and assessed according to the Kasprin-Burrelli, Egolf, and Shames Parent-Child Interaction Scale (Kasprin-Burrelli, et al., 1972).The quality of the parent-child interactions, as measured by the Kasprin-Burrelli, et al., Parent-Child Interaction Scale, improved throughout the study. Thus, it is impossible to state that the treatment was responsible for the improvement. It is hypothesized that the presence of the examiner resulted in the improvement. Mrs. X is a college-educated woman and appears to need adult stimulation. When Mrs. X's need for adult stimulation was met, then her interactions with Jan improved. Thus, although Mrs. X did not modify Jan's interruption behavior, her interactions with Jan did improve throughout the experiment.     

Teaching Contemporary Physics Topics Using Real-Time Data Obtained via the World Wide Web

As a teaching tool, the World Wide Web (WWW) is unprecedented in its ability to transmit information and enhance communication between scientist and student. Just beginning to be developed are sites that actively engage the user in the learning process and provide hands-on methods of teaching contemporary topics. These topics are often not found in the classroom due to the complexity and expense of the laboratory equipment and the WWW is an ideal tool for overcoming this difficulty. This paper presents a model for using the Internet to teach high school students about plasma physics and fusion energy. Students are given access to real-time data, virtual experiments, and communication with professional scientists via email. Preliminary data indicate that student collaboration and student-led learning is encouraged when using the site in the classroom. Scientist/student mentoring is enhanced with this form of communication.     

The American College Counseling Association: A Historical View

The history of college counseling reflects its multifaceted, dynamic character. Numerous works track the historical development of counseling in higher education (Bragdon, 1929; Farnsworth, 1957; Fitzpatrick, 1968; Heppner& Neal, 1983; Siegel, 1968; Williamson, 1939). Contemporary authors also have analyzed current trends and issues facing the college counseling profession (Dean & Meadows, 1995; Steenbarger, 1990; Stone & Archer, 1990). The American College Counseling Association (ACCA) was created and has developed in the context of both history and recent issues in counseling within higher education settings. This article examines factors contributing to the birth and rapid growth of this successful and growing professional association.     

Prenatal Maternal Stress,Child Cortical Thickness,and Adolescent Depressive Symptoms

Prenatal maternal stress predicts subsequent elevations in youth depressive symptoms, but the neural processes associated with these links are unclear. This study evaluated whether prenatal maternal stress is associated with child brain development, and adolescent depressive symptoms using a prospective design with 74 mother child pairs (40 boys). Maternal stress was assessed during pregnancy, child cortical thickness at age 7, and depressive symptoms at age 12. Prenatal maternal stress was associated with less cortical thickness primarily in frontal and temporal regions and with elevated depressive symptoms; child cortical thickness additionally correlated with adolescent depressive symptoms. The observed associations are consistent with the possibility that cortical thickness in superior frontal regions links associations between prenatal maternal stress and adolescent depressive symptoms.     

Pathways of China's PM2.5 air quality 2015–2060 in the context of carbon neutrality

Clean air policies in China have substantially reduced particulate matter (PM_2.5) air pollution in recent years, primarily by curbing end-of-pipe emissions. However, reaching the level of the World Health Organization (WHO) guidelines may instead depend upon the air quality co-benefits of ambitious climate action. Here, we assess pathways of Chinese PM_2.5 air quality from 2015 to 2060 under a combination of scenarios that link global and Chinese climate mitigation pathways (i.e. global 2°C- and 1.5°C-pathways, National Determined Contributions (NDC) pledges and carbon neutrality goals) to local clean air policies. We find that China can achieve both its near-term climate goals (peak emissions) and PM_2.5 air quality annual standard (35 μg/m³) by 2030 by fulfilling its NDC pledges and continuing air pollution control policies. However, the benefits of end-of-pipe control reductions are mostly exhausted by 2030, and reducing PM_2.5 exposure of the majority of the Chinese population to below 10 μg/m³ by 2060 will likely require more ambitious climate mitigation efforts such as China''s carbon neutrality goals and global 1.5°C-pathways. Our results thus highlight that China''s carbon neutrality goals will play a critical role in reducing air pollution exposure to the level of the WHO guidelines and protecting public health.     

Choices for studying choice: Assessing charter school effectiveness using two quasi-experimental methods

Two quasi-experimental methods – fixed effects (FE) and virtual control records (VCR) – were used to measure charter schooling in 14 states and two districts. The new VCR method uses all available observable charter student characteristics and prior performance to create a composite comparison record. A head-to-head comparison of the FE and VCR methods used the same charter students to test the FE control (e.g., the charter student's own traditional public school experience) and the VCR for equivalence. The comparison produced highly similar estimates; charter coefficients were identical in sign and significance and of the same general magnitudes. In an analysis of the sampling fractions included in each method using all available tested charter students, the VCR method was found to produce more generalizable results. In the policy analysis, charter school quality was found to be demographically and geographically uneven with only 19 percent of charter schools outperforming their local markets.
