Understanding the written number system: 6 Year-olds in Argentina and Switzerland

Thirty children in Geneva, Switzerland, 15 middle-class children in Bariloche and 15 lower-class children from a semi-literate or illiterate milieu in Bariloche, Argentina, were tested. All children were aged 6 and attending public schools. Tasks were: (1) judging which of two bi- or tri-digit written numerals was the biggest, and explaining why; and (2) explaining the role played by the different digits in numerals such as 11, 12, 16, 17. Results show that children at these ages use various strategies in task 1: they compare number of digits; read aloud the numerals and refer to number-string knowledge; treat bi- and tri-digits as the sum of their face value parts; and lastly, quite often take both face value and position of digits into account in a correct way. They, however, were not able to explain place-value. Most subjects gave face value interpretations, while a few children account for the whole collection of chips and make part of the chips correspond to one digit, and the other part to the other digit. Differences in performance between the three types of children emerge.     

The Relationship Between Objectified Body Consciousness and Wellness in a Group of College Women

Objectified body consciousness theory provides a framework for understanding young women's negative body experiences and their impact on well‐being. This study examined the impact of body surveillance, body shame, and appearance control beliefs, the 3 components of objectified body consciousness, on wellness in college women. Data indicated a negative relationship between body surveillance and body shame and several components of wellness and a positive relationship between appearance control beliefs and aspects of wellness. Implications are examined.     

School Adjustment in Sixth Graders: Parenting Transitions, Family Climate, and Peer Norm Effects

This study examined whether sixth graders' (mean age = 11.86 years) adjustment to the school context (assessed by grades, achievement scores, and disruptive behavior) was affected by factors from both the family context (represented by students' reports of the number of parenting transitions experienced as well as current levels of supervision, acceptance, autonomy granting, and conflict in the family) and the peer context (represented by students' perceptions of peer norms supporting academic excellence). School adjustment was related to the number of parenting transitions experienced, family climate, and peer norms as well as to higher-order relations involving family climate and peer norms such that ( a ) high grade point averages occurred at only moderate levels of family supervision, ( b ) achievement scores were positively related to supervision at only low levels of family autonomy granting, and ( c ) grade point average was positively related to peer norms at only high levels of family acceptance.     

Mentoring Online about Mentoring: Possibilities and practice

Mentoring is most often associated with direct personal contact between individuals. Computer-based learning, on the other hand, is more associated with the impersonal interaction between human and machine. Recent developments in online technology, however, have paved the way for more personal interactions between people via machines. This article reports on the experience of a university professor and her graduate students as they embarked on learning about the very personal domain of mentoring via face-to-face and online learning. The results in terms of student learning, professional practice and mentoring suggest the benefit of utilizing technology as a support and enhancement to direct personal interaction, not replace it.

Comparison of physiological responses to graded exercise test performance in outrigger canoeing

Abstract

The aim of this study was to establish a graded exercise test protocol for determining the peak physiological responses of female outrigger canoeists. Seventeen trained female outrigger canoeists completed two outrigger ergometer graded exercise test protocols in random order: (1) 25 W power output for 2 min increasing by 7.5 W every minute until exhaustion; and (2) 25 W power output for 2 min increasing by 15 W every 2 min to exhaustion. Heart rate and power output were recorded every 15 s. Expired air was collected continuously and sampled for analysis at 15-s intervals, while blood lactate concentration was measured immediately after and 3, 5, and 7 min after exercise. The peak physiological and performance variables examined included peak oxygen uptake ([Vdot]O_2peak), minute ventilation, tidal volume, ventilatory thresholds 1 and 2, respiratory rate, respiratory exchange ratio, heart rate, blood lactate concentration, power output, performance time, and time to [Vdot]O_2peak. There were no significant differences in peak physiological responses, ventilatory thresholds or performance variables between the two graded exercise test protocols. Despite no significant differences between protocols, due to the large limits of agreement evident between protocols for the peak physiological responses, it is recommended that the same protocol be used for all comparison testing to minimize intra-individual variability of results.     

Cricket fast bowling performance and technique and the influence of selected physical factors during an 8-over spell

The aims of this study were to determine the influence of an 8-over spell on cricket fast bowling technique and performance (speed and accuracy), and to establish the relationship of selected physical capacities with technique and performance during an 8-over spell. Fourteen first-grade fast bowlers with a mean age of 23 years participated in the study. Physical capacities assessed were abdominal strength, trunk stability, selected girth and skinfold measures. During the delivery stride, bowlers were filmed from an overhead and lateral perspective (50 Hz) to obtain two-dimensional data for transverse plane shoulder alignment and sagittal plane knee joint angle respectively. Ball speed was measured by a radar gun and accuracy by the impact point of each delivery on a zoned scoring target at the batter's stumps. Shoulder counter-rotation did not change significantly between overs 2 and 8 for all bowlers, but was significantly related to a more front-on shoulder orientation at back foot impact. When the front-on fast bowlers ( n = 5) were isolated for analysis, shoulder counter-rotation increased significantly between overs 2 and 8. Ball speed remained constant while accuracy showed some non-significant variation during the spell. Shoulder counter-rotation was significantly related to accuracy scores during the second half of the 8-over spell. Chest girth and composition and body composition were significantly related to ball release speed at various times during the spell.     

A DIALOGICAL APPROACH TO CRITICAL BIBLE STUDY: THE USE OF SCHWABIAN DELIBERATION TO INTEGRATE THE WORK OF BIBLE SCHOLARS WITH EDUCATIONAL PHILOSOPHY

This article uses analytic tools provided by Joseph Schwab to address a “practical” problem faced by many liberal religious educational institutions: the tension between historical-critical study of the Bible and an affective connection to it. This problem is painted in broad strokes; then two contemporary Bible scholars, Jeffrey Tigay and Yair Zakovitch, are analyzed for the “principles of enquiry” used in their disciplinary orientations. This analysis is merged with a dialogical hermeneutics approach to text, using the work of Kepnes, Buber, and Gadamer. The article concludes by considering how this study might inform Bible curricula in liberal religious educational contexts.     

Beneficial effect of enriched air nitrox on bubble formation during scuba diving. An open-water study

Bubble formation during scuba diving might induce decompression sickness.

This prospective randomised and double-blind study included 108 advanced recreational divers (38 females). Fifty-four pairs of divers, 1 breathing air and the other breathing nitrox28 undertook a standardised dive (24 ± 1 msw; 62 ± 5min) in the Red Sea. Venous gas bubbles were counted (Doppler) 30–<45 min (early) and 45–60 min (late) post-dive at jugular, subclavian and femoral sites.

Only 7% (air) vs. 11% (air28®) (n.s.) were bubble-free after a dive. Independent of sampling time and breathing gas, there were more bubbles in the jugular than in the femoral vein. More bubbles were counted in the air-group than in the air28-group (pooled vein: early: 1845 vs. 948; P = 0.047, late: 1817 vs. 953; P = 0.088). The number of bubbles was sex-dependent. Lastly, 29% of female air divers but only 14% of male divers were bubble-free (P = 0.058).

Air28® helps to reduce venous gas emboli in recreational divers. The bubble number depended on the breathing gas, sampling site and sex. Thus, both exact reporting the dive and in particular standardising sampling characteristics seem mandatory to compare results from different studies to further investigate the hitherto incoherent relation between inert gas bubbles and DCS.
