A developmental study of the relationship between reading development and the self-system     

Thérèse Bouffard 《European Journal of Psychology of Education - EJPE》1998,13(1):61-74

The aims of this three-year longitudinal study were to examine 1) the concurrent development of different components of the self-system; 2) how the development of this self-system relates to cognitive and metacognitive development in reading; and 3) whether or not there are gender differences both in the development of the self-system as well as in its relation to the development of reading. One hundred and seventy-eight elementary school children were first assessed in the fourth grade and then again in each of the two following years. A similar pattern of intercorrelations between self-system components was evident for boys and girls, and this pattern was quite stable across the three school grades. In addition, similar patterns of moderate relations between the self-system and cognitive and metacognitive development in reading were observed across time. According to these findings, there appears to be some stability, consistency and coherence in how late elementary school children’s beliefs about themselves as learners are organized in their self-system. It is also evident that children of this age are able to make valid self-appraisals of their capabilities.  相似文献

IntroductionThe aims of study were to assess: 1) performance specifications of Atellica 1500, 2) comparability of Atellica 1500 and Iris, 3) the accuracy of both analysers in their ability to detect bacteria.Materials and methodsCarryover, linearity, precision, reproducibility, and limit of blank (LoB) verification were evaluated for erythrocyte and leukocyte counts. ICSH 2014 protocol was used for estimation of carryover, CLSI EP15-A3 for precision, and CLSI EP17 for LoB verification. Comparison for quantitative parameters was evaluated by Bland-Altman plot and Passing-Bablok regression. Qualitative parameters were evaluated by Weighted kappa analysis. Sixty-five urine samples were randomly selected and sent for urine culture which was used as reference method to determine the accuracy of bacteria detection by analysers.ResultsAnalytical specifications of Atellica 1500 were successfully verified. Total of 393 samples were used for qualitative comparison, while 269 for sediment urinalysis. Bland-Altman analysis showed statistically significant proportional bias for erythrocytes and leukocytes. Passing-Bablok analysis for leukocytes pointed to significant constant and minor proportional difference, while it was not performed for erythrocytes due to significant data deviation from linearity. Kappa analysis resulted in the strongest agreements for pH, ketones, glucose concentrations and leukocytes, while the poorest agreement for bacteria. The sensitivity and specificity of bacteria detection were: 91 (59-100)% and 76 (66-87)% for Atellica 1500 and 46 (17-77)% and 96 (87-100)% for Iris.ConclusionThere are large differences between Atellica 1500 and Iris analysers, due to which they are not comparable and can not be used interchangeably. While there was no difference in specificity of bacteria detection, Iris analyser had greater sensitivity.  相似文献

Transactive Teaching in a Time of Climate Crisis     

CARL ANDERS SÄFSTRÖM  LEIF ÖSTMAN 《Journal of Philosophy of Education》2020,54(4):989-1002

This article discusses three problems that need to be tackled when the climate crisis becomes ‘a sustainability issue’ to be taught in schools. The article highlights, first, how knowledge concerning sustainability in schools risks being reduced and made into knowledge about ‘things’. Secondly, it also discusses how students in such a context risk being treated as instruments for ways of being in the world, rather than being subjects with ethical and political concerns for the world in which they live ‘here and now’. Thirdly, as we explore through some empirical examples, such reduction and instrumentalism objectifies both students and nature, which makes an adequate response to the crises obsolete. As an alternative, the article develops a notion of grievability and its importance for adequately responding to all living beings within a project of sustainability. To this end, it develops suggestions for a transactive teaching approach in a time of climate crisis.  相似文献   

Young children's adaptive partner choice in cooperation and competition contexts     

Sebastian Grueneisen  Georgina Török  Anushari Wathiyage Don  Azzurra Ruggeri 《Child development》2024,95(3):1023-1031

Choosing adequate partners is essential for cooperation, but how children calibrate their partner choice to specific social challenges is unknown. In two experiments, 4- to 7-year-olds (N = 189, 49% girls, mostly White, data collection: 03.2021–09.2022) were presented with partners in possession of different positive qualities. Children then recruited partners for hypothetical tasks that differed with respect to the quality necessary for success. Children and the selected partner either worked together toward a common goal or competed against each other. From age 5, children selectively chose individuals in possession of task-relevant qualities as cooperative partners while avoiding them as competitors. Younger children chose partners indiscriminately. Children thus learn to strategically adjust their partner choice depending on context-specific task demands and different social goals.  相似文献   

Relationship between school rhythm and physical activity in adolescents: the HELENA study     

Jérémy Vanhelst  Laurent Béghin  Alain Duhamel  Stefaan De Henauw  Denes Molnar  Germán Vicente-Rodriguez 《Journal of sports sciences》2017,35(16):1666-1673

The aim was to assess the relationship between school rhythm and physical activity (PA) in adolescents. The study included 2024 adolescents (12.5–17.4 years). Participants wore an accelerometer for 7 days. A short school rhythm was defined as a short time at school with short recesses and less time in teaching per day (Group 1). A long school rhythm was defined as a longer time at school with more time in teaching and recess (Group 2). Adolescents in Group 1 performed less moderate to vigorous PA (MVPA) than those in Group 2 per week (P < .0001), especially during school days (recess: 3.9 ± 4.0 vs. 9.8 ± 7.9 min · day^?1; P < .0001; teaching hours: 14.5 ± 9.8 vs. 19.1 ± 12.0 min · day^?1; P < .0001). Adolescents in Group 1 were less likely to meet the PA recommendations than were adolescents in Group 2: 30.7% vs. 34.1% (P < .0001). During school days, the percentage of adolescents who spent more than 2 h · day^?1 in sedentary activities was greater in the Group 1 (P < .001). Our results suggest that leisure-time out-of-school hours is used mainly for sedentary activities, and that school time provides a good opportunity for promoting PA.  相似文献   

Social stratification of culture and leisure in Turkey     

Kemal Aydın 《Cultural Trends》2009,18(4):295-311

Using three sets of survey data, this article explores the variations and social bases of leisure and cultural consumption patterns during the last decade in Turkey. In particular, this article explores the social basis of reading habits of daily newspapers, magazines and journals, going out to movies and the theatre, as well as spending patterns on these and various other cultural activities. Questions addressed in this study are: how are culture and leisure consumptions stratified in contemporary Turkish society, and what types of changes can be detected between 1994 and 2004? In summary, the data indicate that leisure and cultural consumption tend to be stratified by educational and income level and, to some extent, white-collar occupations. Second, households with female heads tended to engage more in “highbrow” consumption, compared to households with male heads.  相似文献

Post-collection acidification of spot urine sample is not needed before measurement of electrolytes     

Tom&#x; &#x;lek  Pavel Musil  Marek P&#x;en ík  Vladimír Pali ka 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2022,32(2)

IntroductionKidney stone formers can have higher oxalate and phosphate salt amounts in their urine than healthy people and we hypothesized that its acidification may be useful. The study aims to compare results of urine concentrations of calcium, magnesium, and inorganic phosphorus in the midstream portion of first voided morning urine samples without (FMU) and with post-collection acidification (FMUa) in kidney stone patients.Materials and methodsThis is a prospective single center study. A total of 138 kidney stone patients with spot urine samples were included in the study. Urine concentrations of calcium, magnesium and inorganic phosphorus were measured with and without post-collection acidification. Acidification was performed by adding 5 µL of 6 mol/L HCl to 1 mL of urine.ResultsThe median age (range) of all participants was 56 (18-87) years. The median paired differences between FMU and FMUa concentrations of calcium, magnesium, and inorganic phosphorus were: - 0.040 mmol/L, 0.035 mmol/L, and 0.060 mmol/L, respectively. They were statistically different: P < 0.001, P < 0.001, P = 0.004, respectively. These differences are not clinically significant because biological variations of these markers are much higher.ConclusionsNo clinically significant differences in urinary calcium, magnesium, and inorganic phosphorus concentrations between FMU and FMUa in patients with kidney stones were found.  相似文献
