Research Findings: Within the flourishing area of research demonstrating the efficacy of emotion-based interventions carried out by trained teachers in educational contexts in increasing children’s emotional skills, this study makes an original contribution to the existing literature by focusing on the effects of this kind of intervention on toddlers’ prosocial and aggressive behavior. Ninety-five 26- to 36-month-olds participated in a 2-month intervention in which trained teachers read emotion-based stories to small groups of children and then either involved them in conversations about emotions (experimental condition) or did not (control condition). Even after we controlled for age and general language ability, the children in the experimental condition were found to outperform the control group on measures of emotion knowledge and emotional-state talk. Furthermore, the intervention fostered gains in prosocial behavior, whereas it did not have a significant effect on the frequency of aggressive actions, which was lower at posttest in both groups. The positive effect of the training program on participants’ prosocial behavior was no longer significant when we controlled for gains in emotion knowledge and emotional-state talk. Practice or Policy: The results encourage the implementation of early educational programs focused on emotion knowledge in order to foster children’s prosocial behavior toward peers. 相似文献

Effects of exercise intensity on salivary antimicrobial proteins and markers of stress in active men 总被引:2,自引:0,他引:2
In the present study, we assessed the effects of exercise intensity on salivary immunoglobulin A (s-IgA) and salivary lysozyme (s-Lys) and examined how these responses were associated with salivary markers of adrenal activation. Using a randomized design, 10 healthy active men participated in three experimental cycling trials: 50% maximal oxygen uptake (VO2max), 75%VO2max, and an incremental test to exhaustion. The durations of the trials were the same as for a preliminary incremental test to exhaustion (22.3 min, sx = 0.8). Timed, unstimulated saliva samples were collected before exercise, immediately after exercise, and 1 h after exercise. In the incremental exhaustion trial, the secretion rates of both s-IgA and s-Lys were increased. An increase in s-Lys secretion rate was also observed at 75%VO2max. No significant changes in saliva flow rate were observed in any trial. Cycling at 75%VOmax and to exhaustion increased the secretion of alpha-amylase and chromogranin A immediately after exercise; higher cortisol values at 75%VO2max and in the incremental exhaustion trial compared with 50%VO2max were observed 1 h immediately after exercise only. These findings suggest that short-duration, high-intensity exercise increases the secretion rate of s-IgA and s-Lys despite no change in the saliva flow rate. These effects appear to be associated with changes in sympathetic activity and not the hypothalamic - pituitary - adrenal axis. 相似文献

This study aims to deliver a school‐based mode of training for in‐service teachers of students with ASD in Hong Kong. The training is delivered following the phases of implementation science, namely, exploration, installation, and implementation. The project team used the theory of mind approach, which enables teachers to engage with students with ASD and to focus on recognizing and reacting to emotions. Participants in this study included four educators from a teacher education institution, three expert teachers, and 19 in‐service teacher trainees. The most salient responses came from trainees who were provided with the opportunity to apply learned skills in their own classrooms immediately and to share the knowledge and skills in dealing with students with ASD in the post‐conference meetings. 相似文献

Introduction:
The contamination of serum or lithium heparin blood with ethylenediaminetetraacetic acid (EDTA) salts may affect accuracy of some critical analytes and jeopardize patient safety. The aim of this study was to evaluate the effect of lithium heparin sample contamination with different amounts of K2EDTA.Materials and methods:
Fifteen volunteers were enrolled among the laboratory staff. Two lithium heparin tubes and one K2EDTA tube were collected from each subject. The lithium-heparin tubes of each subject were pooled and divided in 5 aliquots. The whole blood of K2EDTA tube was then added in scalar amount to autologous heparinised aliquots, to obtained different degrees of K2EDTA blood volume contamination (0%; 5%; 13%; 29%; 43%). The following clinical chemistry parameters were then measured in centrifuged aliquots: alanine aminotranspherase (ALT), bilirubin (total), calcium, chloride, creatinine, iron, lactate dehydrogenase (LD), lipase, magnesium, phosphate, potassium, sodium.Results:
A significant variation starting from 5% K2EDTA contamination was observed for calcium, chloride, iron, LD, magnesium (all decreased) and potassium (increased). The variation of phosphate and sodium (both increased) was significant after 13% and 29% K2EDTA contamination, respectively. The values of ALT, bilirubin, creatinine and lipase remained unchanged up to 43% K2EDTA contamination. When variations were compared with desirable quality specifications, the bias was significant for calcium, chloride, LD, magnesium and potassium (from 5% K2EDTA contamination), sodium, phosphate and iron (from 29% K2EDTA contamination).Conclusions:
The concentration of calcium, magnesium, potassium, chloride and LD appears to be dramatically biased by even modest K2EDTA contamination (i.e., 5%). The values of iron, phosphate, and sodium are still reliable up to 29% K2EDTA contamination, whereas ALT, bilirubin, creatinine and lipase appear overall less vulnerable towards K2EDTA contamination. 相似文献35.

Background
It is still uncertain whether or not avoidance to let disinfectant alcohol dry at the site of venipuncture is a source of spurious hemolysis when drawing venous blood.Methods:
In a consecutive series of 52 outpatients referred for routine laboratory testing, venous blood was drawn by direct venipuncture with (odd group) or without (pair group) wiping 70% isopropyl alcohol at the site of venipuncture. A 3.5 mL evacuated tube with clot activator and gel separator was drawn from a vein of the upper limb, serum was immediately separated with standard centrifugation and tested for potassium, lactate dehydrogenase (LD), aspartate aminotransferase (AST) and hemolysis index (HI) on Roche Cobas.Results:
No specimen was discarded for unsatisfactory venipuncture. No differences for age and gender were observed between groups. As regards the four parameters investigated, no significant differences could be observed between patients in whom blood was drawn with or without letting the alcohol dry. It is also noteworthy that no sample in both groups exceeded the conventional sample rejection threshold of cell-free hemoglobin.Conclusions:
The results of our prospective, randomized study attest that failure to wipe alcohol at the site of venipuncture should not be considered as a potential source of spurious hemolysis when drawing blood. 相似文献36.

The microclimatic analysis of the Petrarca's tomb in Arquà Petrarca, Padua (Italy) was performed to assess the suitability of a closed environment located outdoors respect to the conservation requirements of heritage materials. Results showed that the thermo-hygrometric conditions inside the tomb were not suitable for the conservation of organic materials, like bones and wood. The orientation (north or south) was the main responsible for the different damage features of the two sides of the wooden case housing the human remains inside the tomb. Technical solutions were finally implemented to improve the conservation conditions, thus avoiding further damage. 相似文献

Abstract This article argues for the revitalization of a productive tension between ‘queer’ and ‘theory’ and underscores its necessity for a study of ‘local queer theory.’ While there is an apparent lack of academic queer theory in Hong Kong, there are numerous examples of writings that advance theoretical positions, albeit in unfamiliar guises. The article analyzes three examples of queer writings by Hong Kong authors, penned between 1984 and 2000. Focusing on the texts’ archival effect and affective expression, the analysis demonstrates that these writings form an archive of queer feelings. As a repository of the discomfort and anxiety that are constitutive of queer lives, these writings can offer fruitful interventions into current theoretical debates. The article concludes with a call for more creative and irreverent – in short, queerer – ways of localizing the global phenomenon of queer theory. 相似文献

This investigation compared the attitudes of teachers toward integration of students with disabilities in Haïti and the United States. A sample of 152 high school teachers in Haïti and 216 high school teachers in the United States was asked to complete a background questionnaire and the Opinions Relative to the Integration of Students with Disabilities scale (Antonak & Larrivee, 1995). Results showed that teachers in both countries had similar attitudes toward the integration of students with disabilities. Years of experience was individually correlated with attitudes, but it was not a significant predictor when other variables were included in a multiple regression. Three variables predicted attitudes toward integration of students with disabilities. Teachers’ attitudes explained the largest variance, followed by advanced degree, and range of effective accommodation of different categories of disabilities. 相似文献

Research Findings: Supportive mother–child interactions promote the development of social-emotional competence. Poverty and other associated psychosocial risk factors have a negative impact on mother–child interaction. In spite of Latino children being disproportionately represented among children living in poverty, research on mother–child interactions among economically disadvantaged Latino families remains scarce and results are mixed. The current study used an ecological approach to examine the relationship between maternal cumulative risk, child developmental delay, observed and self-reported quality of the mother–child relationship, time spent in Head Start, and teachers’ and parents’ ratings of social-emotional competence among 106 Latino Head Start children and their mothers. Cumulative risk showed a negative association with observed maternal supportiveness and self-reported quality of the mother–child relationship. Cumulative risk had negative and positive indirect effects, respectively, on child social competence and problem behavior through perceived quality of the mother–child relationship. This association only occurred when parent ratings of child behavior were used. Time spent in Head Start moderated the association between observed maternal supportiveness and social competence. Practice or Policy: Implications for providers and researchers attempting to improve social-emotional competence in disadvantaged Latino children by enhancing positive and supportive parenting practice are discussed. 相似文献
