HIV knowledge and risk among Zambian adolescent and younger adolescent girls: challenges and solutions

In sub-Saharan Africa, young women are at the highest risk of HIV infection. Comprehensive sexuality education and open parent–child communication about sex have been shown to mitigate risky sexual practices associated with HIV. This study aimed to identify sources of HIV prevention knowledge among young women aged 10–14 years and community-based strategies to enhance HIV prevention in Zambia. Focus group discussions were conducted with 114 young women in Zambian provinces with the highest rates (~20%) of HIV. Discussions were recorded, transcribed and coded, and addressed perceived HIV risk, knowledge and access to information. Participants reported that limited school-based sexuality education reduced opportunities to gain HIV prevention knowledge, and that cultural and traditional practices promoted negative attitudes regarding condom use. Parent–child communication about sex was perceived to be limited; parents were described as feeling it improper to discuss sex with their children. Initiatives to increase comprehensive sexuality education and stimulate parental communication about sexual behaviour were suggested by participants. Culturally tailored programmes to increase parent–child communication appear warranted. Community-based strategies aimed at enhancing protective sexual behaviour among those most at risk are essential.     

An association of soviet‐sphere broadcasters: The international radio and television organization

Although American broadcasters are conscious of the role of the North American Regional Broadcasting Agreement, it may well be that few realize the existence of other regional broadcasting agreements and bodies, with different functions, and cast into a different mold. One such body is the International Radio and Television Organization (OIRT) which coordinates the broadcast activities of nations within or allied in varying degree to the sphere of influence of the USSR.     

A world bibliography of selected periodicals on broadcasting

The authors designed two instructional units—role‐playing and traditional—to examine if young children can be taught general and specific intent of television commercials. The results demonstrate that both treatment groups of children, ages six to seven, experienced significant increases in understanding of commercials.     

The Impact of an Inquiry-Based Geoscience Field Course on Pre-service Teachers

The purpose of this quasi-experimental study was to determine the effects of a field-based, inquiry-focused course on pre-service teachers?? geoscience content knowledge, attitude toward science, confidence in teaching science, and inquiry understanding and skills. The field-based course was designed to provide students with opportunities to observe, compare, and investigate geological structures in their natural environment and to gain an understanding of inquiry via hands-on learning activities designed to immerse students in authentic scientific investigation. ANCOVA and MANCOVA analyses examining differences in outcome measures between students in the field experience (n?=?25) and education students enrolled in the traditional, classroom-based course (n?=?37) showed that students in the field course generally had significantly higher scores. Results provide evidence of the value of the field and inquiry-based approach in helping pre-service teachers develop the needed skills and knowledge to create effective inquiry-based science lessons.     

Perceptions of communication in a family relationship and the reduction of intergroup prejudice

From a contact theory perspective, links between variation in young adults' perceptions of communication with their grandparents and attitudes towards older adults are examined. The analysis pays particular attention to variation in communication with multiple grandparents, and finds links between that and perceived variability in the older adult population as a whole. More variation in perceptions of communication with grandparents is associated with perceptions of older adults as more heterogeneous. However, variation in grandparent relationships is associated with more negative attitudes towards older adults on measures of attitudinal central tendency. The results are discussed in terms of intergroup communication processes, contact theory and possible interventions to reduce prejudice in this and other contexts.     

Examining the Role of Self-Regulated Learning Microanalysis in the Assessment of Learners’ Regulation

We examined the degree of convergence among self-regulated learning microanalysis, measures of metacognitive monitoring, and a self-regulated learning questionnaire during reading. Participants' reported strategy use during reading, as measured by self-regulated learning microanalysis, was significantly related to scores on a self-regulated learning questionnaire. Self-monitoring on the microanalytic protocol was significantly related to a measure of metacognitive monitoring as well as to participants' item-level confidence judgments. Participants who made strategy attributions for performance tended to have higher scores on the measure of reading comprehension. Strategic planning and strategy use during reading of the text also predicted comprehension. Implications and future directions for the study of self-regulated learning microanalysis are discussed.     

Shifting the blame in higher education – social inclusion and deficit discourses

The principles of social inclusion have been embraced by institutions across the higher education sector but their translation into practice through pedagogy is not readily apparent. This paper examines perceptions of social inclusion and inclusive pedagogies held by academic staff at an Australian university. Of specific interest were the perceptions of teaching staff with regard to diverse student populations, particularly students from low socio-economic (LSES) backgrounds, given the institution's reasonably high proportion of LSES student enrolment (14%). A mixed-method approach was utilised: (i) in-depth interviews with a representative sample of academic staff and (ii) an online survey targeting all academic staff across the institution. The results point to the dual responsibilities of students and institutions in enacting inclusivity in order to move beyond reductive standpoints that simply apportion blame.     

Culture and Class Influences on Anglo and Puerto Rican Mothers' Beliefs Regarding Long-Term Socialization Goals and Child Behavior

These 2 studies examine culture and socioeconomic status as simultaneous possible sources for group differences in mothers' beliefs regarding desirable and undesirable long-term socialization goals and child behavior. In Study 1, 100 mothers of young toddlers aged 12–24 months from 5 sociocultural groups participated: middle- and lower-class Anglo, middle- and lower-class island Puerto Rican, and lower-class migrant Puerto Rican. Results indicate that culture and socioeconomic status contribute independently to group differences, but that cultural effects appear to be stronger. Study 2 examined cultural differences in perceptions of behaviors using middle-class Anglo and Puerto Rican mothers only. The findings support those of Study 1, suggesting that Anglo and Puerto Rican mothers place differential value on the constructs of Self-Maximization and Proper Demeanor, even when socioeconomic status is controlled for. The findings of these studies have important implications for the culturally sensitive study of the relation between parental beliefs and behaviors.     

Moving mathematics out of the classroom: Using mobile technology to enhance spontaneous focusing on quantitative relations

Spontaneous focusing on quantitative relations (SFOR) has been shown to be a strong predictor of rational number conceptual development in late primary school. The present study outlines an intervention program that examines the possibilities to enhance late primary school students' SFOR tendency. The intervention program harnessed mobile technology in order to allow students to explore and identify quantitative relations in their everyday environment, including situations outside of the classroom. A total of 38 thirteen-year-olds from two classrooms participated in the seven-week long quasi-experimental study. One classroom spent five lessons over five weeks participating in activities which involved uncovering, defining and describing multiplicative relations in their everyday surroundings. In comparison to a business-as-usual control group, results show the intervention to be successful in enhancing SFOR tendency. These results suggest that it is possible to utilize mobile technologies to enhance students' awareness of the possibilities to use quantitative relations as explicit targets of focusing and reasoning in nonexplicitly mathematical situations.     

The validity of endurance running performance on the Curve 3TM non-motorised treadmill

This study aimed to test the validity of a non-motorised treadmill (NMT) for the measurement of self-paced overground endurance running performance. Ten male runners performed randomised 5-km running time trials on a NMT and an outdoor athletics track. A range of physiological and perceptual responses was measured, and foot strike was classified subjectively. Performance time was strongly correlated (r = 0.82, ICC = 0.86) between running modes, despite running time being significantly longer on the NMT (1264 ± 124 s vs. 1536 ± 130 s for overground and NMT, respectively; P < 0.001). End blood lactate concentration and rating of perceived exertion were significantly higher on the NMT compared to overground. Integrated electromyography was significantly lower on the NMT for three muscles (P < 0.05), and mean stride rate was also significantly lower on the NMT (P = 0.04). Cardiorespiratory responses of heart rate, oxygen uptake and expired air volume demonstrated strong correlations (r = 0.68–0.96, ICC = 0.75–0.97) and no statistical differences (P > 0.05). Runners were consistently slower on the NMT, and as such it should not be used to measure performance over a specific distance. However, the strong correlations suggest that superior overground performance was reflected in relative terms on the NMT, and therefore, it is a valid tool for the assessment of endurance running performance in the laboratory.
