The aim of this paper was to study the construction of children’s self-perception relying on Cooley’s hypothesis. More precisely, we were interested in the mediation effect of significant others’ actual appraisal on self-perception by the perception of others’ actual appraisal (i.e., reflected appraisal). First, we argued that this mediation effect would occur in the domains where children have feedback from significant others (here teacher or parents). Second, we took into account two measures of reflected appraisal: reflected appraisal assessed in a classic fashion and appraisal social support assessed with Harter’s scale (1985b). We argued that reflected appraisal assessed in a classic fashion would be a better mediator of the effect of actual appraisal on self-perception by reflected appraisal in comparison to appraisal social support. In order to test these hypotheses, we conducted a study with 126 children (age 8–9), 106 parents and six teachers. The results, taken as a whole, support these hypotheses. 相似文献

The purpose was to examine power output and three-dimensional (3D) kinematic variables in the upper limbs, lower limbs and trunk in elite flat-water kayakers during kayak ergometer paddling. An additional purpose was to analyse possible changes in kinematics with increased intensity and differences between body sides. Six male and four female international level flat-water kayakers participated. Kinematic and kinetic data were collected during three tasks; low (IntL), high (IntH) and maximal (IntM) intensities. No differences were observed in any joint angles between body sides, except for shoulder abduction. Significantly greater range of motion (RoM) values were observed for IntH compared to IntL and for IntM compared to IntL in trunk and pelvis rotation, and in hip, knee and ankle flexion. The mean maximal power output was 610 ± 65 and 359 ± 33 W for the male and female athletes, respectively. The stroke frequencies were significantly different between all intensities (IntL 59.3 ± 6.3; IntH 108.0 ± 6.8; IntM 141.7 ± 18.4 strokes/min). The results showed that after a certain intensity level, the power output must be increased by other factors than increasing the joint angular RoM. This information may assist coaches and athletes to understand the relationship between the movement of the kayaker and the paddling power output. 相似文献

The webbing clothes moth Tineola bisselliella (Hummel, 1823) is one of the most common museum pests and can be found all over the world. The larvae damages objects made of feather, wool, fur, and other keratinaceous materials. Pheromone traps are important tools in integrated pest management, which allow the detection of infestations and evaluation of their extent. Organic-rich dust (detritus) or other materials of animal origin, such as dead birds, can be an alternative food source for the moths. This paper analyzes monitoring data collected with pheromone traps from six different museums in Vienna and Berlin and tries to differentiate between moths resulting from infested objects or moths coming from other food sources, such as organic-rich dust. Annual totals of moths trapped and catch rate (moths per trap) are important guides for selecting appropriate remedial measures. Long-term data (over six years) enabled us to interpret monitoring results and differentiate between active infestation of objects and cleaning or housekeeping problems. However, detailed knowledge of the site and buildings, availability of high-quality food for the larvae, and lack of regular cleaning are also important factors to consider when interpreting the data. 相似文献

Recent laboratory studies have suggested that heart rate variability (HRV) may be an appropriate criterion for training load (TL) quantification. The aim of this study was to validate a novel HRV index that may be used to assess TL in field conditions. Eleven well-trained long-distance male runners performed four exercises of different duration and intensity. TL was evaluated using Foster and Banister methods. In addition, HRV measurements were performed 5 minutes before exercise and 5 and 30 minutes after exercise. We calculated HRV index (TLHRV) based on the ratio between HRV decrease during exercise and HRV increase during recovery. HRV decrease during exercise was strongly correlated with exercise intensity (R = ?0.70; p < 0.01) but not with exercise duration or training volume. TLHRV index was correlated with Foster (R = 0.61; p = 0.01) and Banister (R = 0.57; p = 0.01) methods. This study confirms that HRV changes during exercise and recovery phase are affected by both intensity and physiological impact of the exercise. Since the TLHRV formula takes into account the disturbance and the return to homeostatic balance induced by exercise, this new method provides an objective and rational TL index. However, some simplification of the protocol measurement could be envisaged for field use. 相似文献

According to self-determination theory, when teachers establish an autonomy supportive climate in the classroom, students
demonstrate high levels of self-determination and are intrinsically motivated. The aim of this study was to identify factors
leading teachers (N=336) to report that they create such a climate. We conducted a path analysis in order to examine the respective
roles of teachers’ implicit theories, their seniority, and their perceptions of pressures at work. We also attempted to find
out whether these personal and contextual variables have a direct influence or are mediated by teachers’ self-efficacy. Our
first finding was that a theory of academic ability as a fixed trait caused a drop in the teachers’ reported support for autonomy.
On the other hand, the belief that academic abilities can be improved through students’ own efforts indirectly favored an
autonomy supportive climate by acting positively on the teachers’ self-efficacy. Also, seniority had a significant positive
effect on autonomy support that was direct, but was also mediated by self-efficacy. Finally, perceived pressures had a negative
impact on reported autonomy support, but their influence was also mediated by self-efficacy. 相似文献

Pupils’ self-perceptions: the role of teachers’ judgment controlling for big-fish-little-pond effect
This article aims to study the relationship between teachers’ judgment and pupils’ self-perceptions controlling for the big-fish-little-pond effect (BFLPE). Three studies were conducted among third-grade pupils. Study 1 (n?=?585) focused on pupils’ perceptions of their scholastic competence. Teachers’ judgment and BFLPE were found to have an independent relation with pupils’ self-perceived scholastic competence. Study 2 (n?=?660) replicated the same results of study 1. Study 3 (n?=?683) extended the analysis to other domains of self-perception identified by Harter (Child development, 53, 87–97, 1982). The results showed that the relation with the BFLPE was significant only for pupils’ self-perceived scholastic competence. They also showed that the teachers’ judgment was related to two other domains of self-perception (behavioral conduct and peer acceptance) but was not directly related to pupils’ global self-worth. 相似文献

An integrative model of scholastic judgments: Pupils’ characteristics, class context, halo effect and internal attributions 总被引:1,自引:0,他引:1

This article proposes a model that integrates some of the determinants of scholastic judgment. The model is based on the assumption
that a teacher’s judgment in a particular discipline is influenced by different variables: the pupil’s actual performance
in the discipline, his/her actual performance in other disciplines (halo effect), the average performance of the class in
the discipline (class context effect), the pupil’s individual characteristics such as whether he/she has ever repeated a grade
and the teacher’s perception of the pupils’ causal explanations. Furthermore, the model proposes that a teacher’s perceptions
are related to the pupil’s spontaneous expression of causality, which in turn is influenced by the pupil’s knowledge of the
social value of causal explanations. In order to test the validity of the proposed model, the authors conducted a study in
a real classroom setting on a population of 663 pupils from 38 classes (3rd grade) and their respective teachers. Path analyses
showed that the theoretical model fit the data to a satisfactory extent. However, a comparison of the fit indexes of the theoretical
model and two alternative models (one nonhierarchical and one hierarchical) showed that the initial theoretical model could
be significantly improved by additional paths. 相似文献
