Sexuality education in Europe: an overview of current policies

Comprehensive sexuality education is one of the most important tools to ensure that young people have the information they need to make healthy and informed choices. The aim of this article is, firstly, to outline general issues about sexuality education pertaining to curriculum content, the didactic methods used, agencies involved, political support, coverage and adequacy of provision and barriers to effective sexuality education in Europe. Secondly, the current state of sexuality education in most European Union member states and Norway is described, enabling a Europe-wide comparison of country experiences in the field. This reveals a wide variety of didactic methods and policies that have shaped the provision of sexuality education and the ease and difficulties with which the subject can be implemented, and at what age and in what form it is available.     

The audience for television news interview programs

An experiment investigated if graphic censorship disclaimers affect memory or thought elaboration for television news stories of the 1991 Persian Gulf war. Viewer assessment of the credibility of censored news also was considered. Subjects listed their thoughts about each story, and their memory was tested as recognition latency. Subjects who rated the credibility of censored news as moderate scored highest on the memory task, but listed the fewest number of negative mentions about the government named as censor in the stories. Under some conditions, results show that the more viewers thought about the source of the censorship, the lesser they remembered images from the stories.     

How Dynamic Visualization Technology can Support Molecular Reasoning

This paper reports the results of a study aimed at exploring the advantages of dynamic visualization for the development of better understanding of molecular processes. We designed a technology-enhanced curriculum module in which high school chemistry students conduct virtual experiments with dynamic molecular visualizations of solid, liquid, and gas. They interact with the visualizations and carry out inquiry activities to make and refine connections between observable phenomena and atomic level processes related to phase change. The explanations proposed by 300 pairs of students in response to pre/post-assessment items have been analyzed using a scale for measuring the level of molecular reasoning. Results indicate that from pretest to posttest, students make progress in their level of molecular reasoning and are better able to connect intermolecular forces and phase change in their explanations. The paper presents the results through the lens of improvement patterns and the metaphor of the “ladder of molecular reasoning,” and discusses how this adds to our understanding of the benefits of interacting with dynamic molecular visualizations.     

Biceps femoris long head muscle fascicle length does not differ between sexes

ABSTRACT

Hamstring strain injury (HSI) rates are higher for males vs. females. This cross-sectional study investigated if inherent differences in biceps femoris long head (BF_LH) fascicle length (Lf) exist between recreationally active males and females (i.e., individuals without specific training practice history). Twenty-four young healthy participants (12 males; 12 females) had their BF_LH muscle architecture (Lf, pennation angle [θp], and muscle thickness [MT]) measured using B-mode ultrasonography. Eccentric and isometric knee flexion strength were also assessed. BF_LH Lf did not differ between sexes when expressed in absolute terms (males, 81.5 ± 14.7 mm; females, 73.6 ± 15.9 mm, P = 0.220, effect size (ES) = 0.52) or relative to femur length (0.140 ≤ P ≤ 0.220, ES = 0.63). Similarly, BF_LH θp did not differ between sexes (P = 0.650) but BF_LH MT was 18.9% larger for males vs. females (P = 0.024, ES = 0.99). Isometric and eccentric knee flexion strength was greater for males vs. females in absolute terms ([both] P < 0.001, 2.00 ≤ ES ≤ 2.27) and relative to body mass ([both] P < 0.001, 1.93 ≤ ES ≤ 2.13). In conclusion, factors other than BF_LH Lf seem likely to be implicated in higher male vs. female HSI rates.     

Sample Size Comparisons Involving the Randomized Response Technique

The purpose of the present paper is to demonstrate how many more subjects are required to achieve equal power when testing certain hypotheses concerning proportions if the randomized response technique is employed for estimating a population proportion instead of the conventional technique.     

Variables that influence the environmental behavior of adults

This study focuses on understanding the factors that encourage adults’ environmental behavior. This mixed approach methodology study used 10 Likert type questionnaires to collect data about nine cognitive and affective components that might influence environmental behavior. The qualitative data was collected through open questions and interviews. The main sample included 656 participants from amongst Israel’s working population. The questionnaires were found both reliable and valid. Most of the explored cognitive and affective aspects appeared to act as predictors of environmental behavior. The study indicates that environmental behavior is driven by ‘egoistic’ concerns rather than by altruistic views and motivations.     

Global private higher education: an empirical profile of its size and geographical shape

Societies’ relative use of private and public services is an abiding and significant issue of scholarly and policy interest. For higher education, however, there has hitherto been no comprehensive dataset and, accordingly, no extensive, reliable analysis of the private-public distribution. As this article provides both the dataset and the analysis, it allows us to discover both the size and geographical shape of global private higher education. Having grown greatly for decades, the private sector now holds a third (32.9%) of the world’s total higher education enrollment. We find striking patterns of concentration and dispersion. The several largest country systems account for much of the private enrollment but, simultaneously, private sectors now exist in all but a few systems; a stunning 97.6% of the world’s present enrollment is in systems with dual-sector provision. Societies no longer rely exclusively on public provision. We discover too that private enrollment concentrates mostly in developing regions, though it is noteworthy in developed regions as well. Asia and Latin America are the twin giants but in all regions, at least 10% of students are in the private sector.     

An analysis of the ecological components within a text structure intervention

The Component Model of Reading expanded upon the Simple View of Reading by adding an ecological and psychological component. Elements of the ecological component include teacher knowledge, information provided in textbooks, and teacher instructional practices. In this study, the authors examined the extent of teacher knowledge about text structure, the extent to which textbooks focused on text structure related skills and strategies as well as the percentage each skill and strategy was covered in lessons and teacher instructional practices. Such analysis shows that although text structure interventions may have positive effects on student reading comprehension, there are multiple elements of the ecological component that may be counteracting the benefits of the intervention. First, teachers have a limited knowledge of the five common text structures. Second, textbooks systematically minimize text structure instruction and only cover comprehension skills and strategies sporadically throughout a year-long curriculum. Third, teacher learning of text structures and change in practice was moderated by these ecological factors including textbook scheduled instruction and administrator support.
