A Lost Decade? Laszlo Radvanyi and the Origins of Public Opinion Research in Mexico, 1941-1952

This article documents public opinion research activities inMexico in the 1940s and the role played by Hungarian professorLászló Radványi, who immigrated to thatcountry at the height of World War II. Our research relies onseveral of Radványi's publications archived in differentcountries, as well as on interviews with family, acquaintances,and experts on the work of his wife, the German poet Anna Seghers.During his years in Mexico, Radványi founded the ScientificInstitute of Mexican Public Opinion, in 1941, and the InternationalJournal of Opinion and Attitude Research, in 1947—a forefatherof today's IJPOR. He was also a founding member of WAPOR. Hisearly "sample surveys" raised important methodological issuesand recorded opinion results that reflect the vibrant timesof war and policy making in a modernizing country. However,Radványi's contribution to the profession has been virtuallyforgotten. Until now, accounts about how public opinion researchbegan in Mexico either ignored Radványi's works or reducedhis ten years of survey research to a single footnote. Thisarticle is an attempt to fill this enormous omission and highlightsome of Radványi's contributions to these early stagesof survey research.     

Does school physical education really contribute to accelerometer-measured daily physical activity and non sedentary behaviour in high school students?

Physical education has been highlighted as an important environment for physical activity promotion, however, to our knowledge there are no previous studies examining the contribution of physical education to daily accelerometer-measured physical activity and non sedentary behaviour. The purpose was to compare the accelerometer-measured physical activity and sedentary behaviour between physical education, non-physical education and weekend days in adolescents. Of the 394 students from a Spanish high school that were invited to participate, 158 students (83 boys and 75 girls) aged 13–16 years were analyzed (wear time ≥ 600 min). Participants’ physical activity and sedentary behaviour were objectively-measured by GT3X+ accelerometers during physical education (one session), non-physical education and weekend days. Results indicated that overall adolescents had statistically significant greater physical activity levels and lower values of sedentary behaviour on physical education days than on non-physical education and weekend days (e.g., moderate-to-vigorous physical activity = 71, 54 and 57 min; sedentary = 710, 740 and 723 min) (p < 0.05). Physical education contributes significantly to reducing students’ daily physical inactivity and sedentary behaviour. Increasing the number of physical education classes seems to be an effective strategy to reduce the high current prevalence of physical inactivity and sedentary behaviour in adolescence.     

Impact of interactive online units on learning science among students with learning disabilities and English learners

The purpose of this study was to document the design, classroom implementation, and effectiveness of interactive online units to enhance science learning over 3 years among students with learning disabilities, English learners, and general education students. Results of a randomised controlled trial with 2,303 middle school students and 71 teachers across 13 schools in two states indicated that online units effectively deepened science knowledge across all three student groups. Comparing all treatment and control students on pretest-to-posttest improvement on standards-based content-specific assessments, there were statistically significant mean differences (17% improvement treatment vs. 6% control; p?相似文献   

Educational Neuromyths Among Teachers in Latin America

Neuroscientific knowledge has undeniably gained interest among educators worldwide. However, not all “brain facts” believed by teachers are supported by science. This study sought to evaluate the belief in these so‐called neuromyths among 3,451 Latin American teachers. We found that, consistent with prior research among teachers in other geographic areas, teachers in Latin America hold major misconceptions about neuroscience, especially as it relates to factual information about its structure and functioning. Differences across South American nations were observed with moderate and slight effect sizes for general knowledge of the brain and neuromyths, respectively. Teachers working in higher education had slightly superior performance. Teachers at all levels who reported knowing more about the brain, however, were more likely to believe invalid assertions known as neuromyths. These results shed light on trends in the field of education, hoping to encourage the development of strategies aimed at correcting the use of science as it relates to education. The implications regarding teaching practice, policy, and teacher training are discussed.     

Visuospatial Orientation Learning through Virtual Reality for People with Severe Disability

This study aims to test how an intervention based on virtual reality (VR) may enhance visuospatial skills amongst people with disability. A quasi-experimental intra-group study was therefore conducted. Participants were 20 people with severe disability (65% males; 34.35 years, on average, and 84.95% of disability rate according to the Andalusian Government index). Intervention consisted of 15 sessions of active navigation using a VR building similar to the participants’ day rehabilitation centre with the task of locating different rooms and objects. The time spent and errors in route in the virtual and the real environments were measured before and after the intervention. Additionally, participants had to fill out a map location task. As a result, participants showed fewer errors and less time at post-intervention assessments even with non-trained stimuli (p < .05). These results demonstrate the usefulness of VR-based interventions with active navigation to accelerate orientation learning in real-life situations.     

Sexual and reproductive health education attitudes and experience in India: how much support is there for comprehensive sex education? Findings from an Internet survey

This study assessed the extent to which an Internet-recruited sample of residents of India was supportive of the provision of comprehensive sexual education in school in a country where youth sexual health is poor. We sought to determine whether attitudes differed for those of varying demographic backgrounds (age, sex, education level, religion), the extent of support for comprehensive coverage, the school or age levels deemed appropriate for delivery, and whether own sex education history influenced support. We conducted an anonymous online survey with 1140 Indian adults using crowdsourcing methods. We found widespread support for the provision of sex education to youth in India among members of our largely well educated, middle-class sample. However, most participants believed sex education should be provided relatively late (i.e., in mid- to late-adolescence). Few opposed sex education altogether and attitudes were not predicted by background, own school-based sex education, or parent-child communication about sex. Less than one-third of participants endorsed the coverage of all topics, indicating that support for truly comprehensive coverage was not strong. However, the findings counter politicised efforts to ban sex education by state leaders despite the availability of a progressive, comprehensive curriculum offered by the Central government.     

The gross anatomy course: An analysis of its importance

The gross anatomy dissection course is a cost‐intensive piece of undergraduate medical education that students and professionals alike describe as very important within the overall medical curriculum. We sought to understand more explicitly students' valuation of gross anatomy as an “important” course and so developed a quantitative longitudinal questionnaire. Medical students (n = 124) enrolled in the winter term 2006/2007 gross anatomy course at the Ulm University Faculty of Medicine were surveyed anonymously prior to, in the middle of, and at the end of the dissection course. Subgroups of students expressing rising or falling opinions of course value were identified and correlated with student opinions about the course's ability to convey professional competencies. Five‐point Likert scales were used for each survey item, which included such standardized instruments as the NeoFFI, BSI, and FBM. The study confirmed that medical students believe dissection to be valuable. Students indicated that participation in the course facilitated acquisition of anatomy knowledge as well as skills related to teamwork, coping with stress, and, to a lesser extent, time management. Students also noted that they developed less empathy than expected beforehand. Significant subgroup differences were observed relative to the competencies of teamwork, stress coping strategies, and empathy, as well as in students' stress levels associated with having to take a dissection course. Our study builds on previous work that has shown dissection courses help students develop professional competencies. The increase in professionalism might be a reason for the generally high value students place on the gross anatomy dissection course, Anat Sci Educ 3:3–11, 2010. © 2010 American Association of Anatomists.     

Children's Vulnerability to Interparental Conflict: The Protective Role of Sibling Relationship Quality

This study tested whether the strength of the mediational pathway involving interparental conflict, adolescent emotional insecurity, and their psychological problems depended on the quality of their sibling relationships. Using a multimethod approach, 236 adolescents (M_age = 12.6 years) and their parents participated in three annual measurement occasions. Tests of moderated mediation revealed that indirect paths among interparental conflict, insecurity, and psychological problems were significant for teens with low, but not high, quality bonds with siblings. High-quality (i.e., strong) sibling relationships conferred protection by neutralizing interparental conflict as a precursor of increases in adolescent insecurity. Results did not vary as a function of the valence of sibling relationship properties, adolescent sex, or gender and age compositions of the dyad.     

The Librarian's Role in Linking Patients to Their Personal Health Data and Contextual Information

The objective of this project was to make an institution's patients aware of a new patient portal with contextual links to MedlinePlus. Through partnerships with information technology personnel and LSU Health Shreveport clinics, the Health Sciences Library created and distributed promotional and educational materials and instructed patients on how to use MyChart and access reliable consumer health information via MedlinePlus Connect. Although most patients were not interested in coming to the library for demonstrations, many of them expressed interest in using MyChart. The contextual information in MedlinePlus Connect worked well for most topics. The institutional team leader for MyChart expressed gratitude for librarian involvement.
