Development of Math Attitudes and Math Self-Concepts: Gender Differences,Implicit–Explicit Dissociations,and Relations to Math Achievement     

Dario Cvencek  Ružica Brečić  Dora Gaćeša  Andrew N. Meltzoff 《Child development》2021,92(5):e940-e956

Three hundred and ninety-one children (195 girls; M_age = 9.56 years) attending Grades 1 and 5 completed implicit and explicit measures of math attitudes and math self-concepts. Math grades were obtained. Multilevel analyses showed that first-grade girls held a strong negative implicit attitude about math, despite no gender differences in math grades or self-reported (explicit) positivity about math. The explicit measures significantly predicted math grades, and implicit attitudes accounted for additional variance in boys. The contrast between the implicit (negativity for girls) and explicit (positivity for girls and boys) effects suggest implicit–explicit dissociations in children, which have also been observed in adults. Early-emerging implicit attitudes may be a foundation for the later development of explicit attitudes and beliefs about math.  相似文献   

Advances in the application of information technology to sport performance

This paper overviews the diverse information technologies that are used to provide athletes with relevant feedback. Examples taken from various sports are used to illustrate selected applications of technology-based feedback. Several feedback systems are discussed, including vision, audition and proprioception. Each technology described here is based on the assumption that feedback would eventually enhance skill acquisition and sport performance and, as such, its usefulness to athletes and coaches in training is critically evaluated.  相似文献   

Nanoparticle image velocimetry at topologically structured surfaces     

Gea O. F. Parikesit  Jeffrey S. Guasto  Salvatore Girardo  Elisa Mele  Ripalta Stabile  Dario Pisignano  Ralph Lindken    Jerry Westerweel 《Biomicrofluidics》2009,3(4)

Nanoparticle image velocimetry (nano-PIV), based on total internal reflection fluorescent microscopy, is very useful to investigate fluid flows within ∼100 nm from a surface; but so far it has only been applied to flow over smooth surfaces. Here we show that it can also be applied to flow over a topologically structured surface, provided that the surface structures can be carefully configured not to disrupt the evanescent-wave illumination. We apply nano-PIV to quantify the flow velocity distribution over a polydimethylsiloxane surface, with a periodic gratinglike structure (with 215 nm height and 2 μm period) fabricated using our customized multilevel lithography method. The measured tracer displacement data are in good agreement with the computed theoretical values. These results demonstrate new possibilities to study the interactions between fluid flow and topologically structured surfaces.  相似文献   

The Relationship Between Attitudes Toward Diversity and Overall Satisfaction of University Students by Race     

Edward G. Helm  William E. Sedlacek  Dario O. Prieto 《Journal of College Counseling》1998,1(2):111-120

First- and 3rd-year university students were surveyed regarding cultural attitudes and climate. Comfort in cross-cultural situations and respect for other cultures correlated with overall satisfaction for all students. However, the more Asian Americans, Hispanic Americans, and Whites were aware of diversity and changing their behavior accordingly, the less satisfied they were. Awareness of diversity was not related to overall satisfaction for African Americans.  相似文献   

An integrated model of school students’ academic achievement and life satisfaction. Linking soft skills,extracurricular activities,self-regulated learning,motivation, and emotions

The role of soft skills at school is still debated, but they have emerged as important factors for students’ academic achievement and life satisfaction. This study focuses on the combined influence of soft skills (in terms of adaptability, curiosity, leadership, initiative, perseverance, and social awareness), extracurricular activities, achievement emotions, self-regulated learning, motivation, and cognitive abilities on academic achievement and life satisfaction. A sample of 603 students (5th to 12th graders) participated in the study. The results of a Bayesian path analysis based on meta-analytical priors show that soft skills were (i) directly positively associated with students’ achievement emotions, self-regulated learning, motivation, and life satisfaction and (ii) indirectly related with academic achievement through the mediation of self-regulated learning and motivation. On the other hand, only soft skills and achievement emotions were directly related to life satisfaction. Extracurricular activities showed a positive association with both soft skills and cognitive abilities. These results are the first to demonstrate the importance of soft skills and extracurricular activities when integrating all the above-mentioned factors in a model of students’ academic achievement and life satisfaction.

The Adult Parental Acceptance–Rejection Questionnaire: A Cross-Cultural Comparison of Italian and American Short Forms     

Vincenzo Paolo Senese  Dario Bacchini  Maria C. Miranda  Cecilia Aurino  Fortuna Somma  Giuseppina Amato 《Parenting, science and practice》2016,16(4):219-236

Objective. The aims of this article were to test the measurement invariance of the Italian and American versions of the Adult Parental Acceptance–Rejection Questionnaire and to compare adults’ remembrances of parental acceptance–rejection across the two nations. Design. The Adult Parental Acceptance–Rejection Questionnaire was administered to 564 Italian adults (M = 23.04 years) and 509 U.S. American adults (M = 22.09 years), matched by gender and age. The measurement invariance of the Parental Acceptance–Rejection Questionnaire was first established by means of multi-group confirmatory factor analyses. Results. The Parental Acceptance–Rejection Questionnaire is fully invariant across the two cultures, and adults organize their remembrances of mothers’ and fathers’ parenting around the same four classes of behavior in both nations. Italian and American adults tend to remember their parents as having been quite loving, with Italian parents being remembered as slightly less warm and more hostile than American parents. Conclusions. The full invariance of the Parental Acceptance–Rejection Questionnaire across the two populations represents additional strong evidence for the universality of interpersonal acceptance–rejection theory. Measurement invariance also confirmed that the Adult Parental Acceptance–Rejection Questionnaire (short form) can be used to measure adult remembrances of parental acceptance–rejection across these two populations.  相似文献   

Integration in Italian schools: teachers' perceptions regarding day-to-day practice and its effectiveness     

Dario Ianes  Heidrun Demo  Francesco Zambotti 《International Journal of Inclusive Education》2013,17(6):626-653

Italy is famous for having the highest percentage of students with disabilities attending ‘the school for all’ (integration). However, in recent studies, the reality of integration seems to be more complex. Integration has reached some important goals (e.g. longer school careers), but while the Italian school system envisages the full participation of all students in normal class activities, there are various problems with the way in which integration is managed day-to-day. This study has two aims: to ascertain the extent to which the Italian legislation on integration is applied in practice and to assess the effectiveness of integration in terms of reaching the learning and social development objectives for students with disabilities and the class as a whole. The article describes the data collected though an online questionnaire compiled by 3230 Italian school staff members, mostly teachers. First, it shows that the integration experience of most of the students with disabilities takes the form of partial participation in class activities. Reasons for it are hypothesised. Second, the teachers' level of satisfaction with the learning and social skills of both students with disabilities and the class is generally positive. A although by no means outstandingly so.  相似文献   

Contrast agent-free sonoporation: The use of an ultrasonic standing wave microfluidic system for the delivery of pharmaceutical agents     

Carugo D  Ankrett DN  Glynne-Jones P  Capretto L  Boltryk RJ  Zhang X  Townsend PA  Hill M 《Biomicrofluidics》2011,5(4):44108-4410815

Sonoporation is a useful biophysical mechanism for facilitating the transmembrane delivery of therapeutic agents from the extracellular to the intracellular milieu. Conventionally, sonoporation is carried out in the presence of ultrasound contrast agents, which are known to greatly enhance transient poration of biological cell membranes. However, in vivo contrast agents have been observed to induce capillary rupture and haemorrhage due to endothelial cell damage and to greatly increase the potential for cell lysis in vitro. Here, we demonstrate sonoporation of cardiac myoblasts in the absence of contrast agent (CA-free sonoporation) using a low-cost ultrasound-microfluidic device. Within this device an ultrasonic standing wave was generated, allowing control over the position of the cells and the strength of the acoustic radiation forces. Real-time single-cell analysis and retrospective post-sonication analysis of insonated cardiac myoblasts showed that CA-free sonoporation induced transmembrane transfer of fluorescent probes (CMFDA and FITC-dextran) and that different mechanisms potentially contribute to membrane poration in the presence of an ultrasonic wave. Additionally, to the best of our knowledge, we have shown for the first time that sonoporation induces increased cell cytotoxicity as a consequence of CA-free ultrasound-facilitated uptake of pharmaceutical agents (doxorubicin, luteolin, and apigenin). The US-microfluidic device designed here provides an in vitro alternative to expensive and controversial in vivo models used for early stage drug discovery, and drug delivery programs and toxicity measurements.  相似文献

Sliding mode optimal control for linear systems     

Michael Basin  Pablo Rodriguez-Ramirez  Antonella Ferrara  Dario Calderon-Alvarez 《Journal of The Franklin Institute》2012,349(4):1350-1363

This paper addresses the optimal control problem for a linear system with respect to a Bolza–Meyer criterion with a non-quadratic non-integral term. The optimal solution is obtained as a sliding mode control, whereas the conventional linear feedback control fails to provide a causal solution. Performance of the obtained optimal controller is verified in the illustrative example against the conventional LQ regulator that is optimal for the quadratic Bolza–Meyer criterion. The simulation results confirm an advantage in favor of the designed sliding mode control.  相似文献
