A New Twist on Studying the Development of Dynamic Spatial Transformations: Mental Paper Folding in Young Children

The relation of spatial skills to academic success in areas such as math and science has sparked discussion in early education around how spatial thinking skills might be included in early schooling. Planning and evaluating new curricula or interventions requires understanding these skills and having the means to assess them. Prior developmental research focused primarily on one aspect of dynamic spatial transformations (DST), namely mental rotation. This study broadens our knowledge by addressing another important DST, namely mental folding. We devised a new test suitable for young children. Performance of 180 children between 4 and 7 years suggests that mental folding appears at around 5.5 years of age, although there were also marked individual differences. These data on the emergence of DST suggest that educational programs targeting this skill could start in preschool or kindergarten and provide a means to assess the effectiveness of such efforts.     

Toddlers' Attachment Security to Child-Care Providers: The Safe and Secure Scale

Attachment relationships of toddlers (N = 45) to their child-care providers were investigated. Children's behaviors with their mothers were observed at home at 24 months and with their child-care providers at 26 months. Attachment Q-Sort procedures were used at home (90 items) and in child care (78 items); the latter yielded a 15-item Safe and Secure Scale describing the safe haven and secure base functions of attachment relationships in child care—being able to (a) seek and receive positive attention, (b) feel safe and protected, (c) receive support for exploration, (d) receive consolation when distressed, and (e) seek and accept assistance. Independent observational measures of child-care quality also were obtained at 24 months. As hypothesized, the Safe and Secure Scale was related to proximal rather than distal indicators of child-care quality, and it was a stronger measure than the child-caregiver Q-security score that was based on all 78 items. Child-mother and child-caregiver security were significantly related.     

Careers guidance services in a changing Europe

Current initiatives designed to develop stronger international co-operation between guidance services within the European Community are outlined. The implications of extending the Community to cover other European countries are discussed. The issue is raised of whether a common European approach to guidance is likely to emerge, and whether it is likely to differ from American approaches. Adapted and updated version of a paper presented at the International Conference of the International Association for Educational and Vocational Guidance held at the University of Lisbon, Portugal, on 9–13 September 1991.     

Effects of 12 weeks of combined training without caloric restriction on inflammatory markers in overweight girls

The objective of the present study was to investigate the effects of combined training without caloric restriction on inflammatory markers in overweight girls. Thirty-three girls (13–17 years) were assigned into overweight training (n = 17) or overweight control (n = 16) groups. Additionally, a normal-weight group (n = 15) was used as control for the baseline values. The combined training programme consisted of six resistance exercises (three sets of 6–10 repetitions at 60–70% 1 RM) followed by 30 min of aerobic exercise (walking/running) at 50–80% VO_2peak, performed in the same 60 min session, 3 days/weeks, for 12 weeks. Body composition, dietary intake, aerobic fitness (VO_2peak), muscular strength (1 RM), glycaemia, insulinemia, lipid profile and inflammatory markers (C-reactive protein, interleukin-6, tumour necrosis factor-alpha, interleukin-10, leptin, resistin and adiponectin) were measured before and after intervention. There was a significant decrease in body fat (P < 0.01) and increase in fat-free mass (P < 0.01), VO_2peak (P < 0.01), 1 RM for leg press (P < 0.01) and bench press (P < 0.01) in the overweight training group. Concomitantly, this group presented significant decreases in serum concentrations of C-reactive protein (P < 0.05) and leptin (P < 0.05), as well as in insulin resistance (P < 0.05) after the experimental period. In conclusion, 12 weeks of combined training without caloric restriction reduced inflammatory markers associated with obesity in overweight girls.     

Why We Watch: Factors Affecting Exposure to Tragic Television News

This study explored the reasons people expose themselves to news depicting tragic events. A total of 376 undergraduates completed anonymous questionnaires about their responses to news coverage of the events of September 11. The study examined the extent to which individual differences in empathy gave rise to news viewing motives (surveillance, reassurance, curiosity), and how these variables, as well as negative emotional responses (anger, sadness, fear), were related to news interest and exposure. Both empathy and emotional responses were associated in predictable ways with interest in news coverage and selective exposure to specific types of news stories (e.g., casualty news, positive news). The results demonstrate that considering affective motivations can enrich our understanding of how and why people use news media. Limitations and suggestions for future research are discussed.     

On rubrication of the division <Emphasis Type="Italic">spintronics</Emphasis> in a separate edition of the abstract journal of the VINITI RAS <Emphasis Type="Italic">solid-state physics</Emphasis> (<Emphasis Type="Italic">Electrical Properties</Emphasis>)

The necessity for publishing a separate abstract journal on spintronics, which is a new, rapidly developing branch of physics, is substantiated. The interest in spintronics, which is the study of fundamental processes involving the simultaneous transport of both electron charge and electron spins in solids, as well as the interaction of electrons with a magnetic grating, is determined not only by its fascinating prospects but also the results that have already achieved. The spin and charge “degrees of freedom” open possibilities for the creation of semiconducting devices with parameters that are much superior to the existing ones and also the construction of devices that do not have analogues at present. First of all, this will permit problems of information transmission and processing to be solved in a new way. A detailed rubrication on spintronics is given in order to discuss the possibility of publishing a separate edition of an abstract journal devoted to spintronics.
