This study aimed to (1) evaluate the effect of hand shaking during recovery phases of intermittent testing on the time–force characteristics of performance and muscle oxygenation, and (2) assess inter-individual variability in the time to achieve the target force during intermittent testing in rock climbers. Twenty-two participants undertook three finger flexor endurance tests at 60% of their maximal voluntary contraction until failure. Performances of a sustained contraction and two intermittent contractions, each with different recovery strategies, were analysed by time–force parameters and near-infrared spectroscopy. Recovery with shaking of the forearm beside the body led to a significantly greater intermittent test time (↑ 22%, P?P?P?相似文献   

#OscarsSoWhite: how Stuart Hall explains why nothing changes in Hollywood and everything is changing     

Isabel Molina-Guzmán 《Critical Studies in Media Communication》2016,33(5):438-454

ABSTRACT

Stuart Hall’s work on culture, representation, ideology and hegemony positions Hollywood as a cultural institution informed by and informative of US social values and norms. Thus contemporary debates over Hollywood's diversity are indicative of broader social conflicts. Empirically the article examines 2014–2015 news coverage of Hollywood to question the Hollywood paradox—the lack of diversity in film/TV production yet TV’s increasing shift towards on-screen diversity. It maps three discursive frames: Hollywood exceptionalism, economic imperatives, and institutionalized racism and sexism. The article concludes by using Hulu’s East Los High to reflect on TV’s digital turn and innovative models in production and representation.  相似文献   

Mathematics-related anxiety and attitudes: examining the impact among Latina preservice teachers     

Cynthia Gautreau  Michelle VanderVeldt Brye  Christina Lunceford 《Journal of Latinos & Education》2016,15(1):26-38

The purpose of this study was to investigate mathematics-related anxiety and attitudes among Latina preservice teachers. Three sections from the Inventory of Mathematics Attitudes, Experience, and Self Awareness were administered to preservice teachers enrolled in a curriculum and instruction mathematics course during the 1st semester of a 2-semester credential program. Pre- and postsurvey data were examined among female students. There were significant differences on 5 statements that suggest positive perceptions about mathematics and 5 statements that suggest negative perceptions about mathematics. We discuss strategies to reduce mathematics anxiety and address attitudes in preservice teachers.  相似文献   

Academic socialization,parental educational expectations,and academic self‐efficacy among Latino adolescents     

Fernanda L. Cross  Aixa D. Marchand  Michael Medina  Andrea Villafuerte  Deborah Rivas‐Drake 《Psychology in the schools》2019,56(4):483-496

This study examined the direct association between parental educational expectations and adolescents’ academic self‐efficacy, as well as the moderating influence of parental academic socialization messages. Participants were 148 Latino parent–adolescent dyads with the majority of Mexican origin (80.4%). Most of the parent participants were mothers (85.8%). Adolescents were 13 (46%) or 14 (54%) years of age, and 53% identified as female. Adolescents reported their academic self‐efficacy and perceptions of their parents’ educational expectations; parents reported on their academic socialization messages of shame/pressure and effort regarding academics. The results suggest that, after accounting for parents’ level of education and immigrant status, parental educational expectations were positively associated with adolescent academic self‐efficacy. This association was stronger among adolescents whose parents reported transmitting fewer messages of shame/pressure and academic effort. These results point to the importance of nuances in the content and type of academic socialization messages within Latino families.  相似文献   

Beyond educational attainment: The importance of skills and lifelong learning for social outcomes. Evidence for Europe from PIAAC          下载免费PDF全文

Empirical evidence suggests that educational attainment nurtures people's social outcomes and promotes active participation in society and stability. However, it is unclear to what extent other types of human capital also correlate with social outcomes. Hence, we explored the opportunity offered by the PIAAC survey through its provision of information on educational attainment, observed individual key skills proficiency, and participation in adult education and training (adult lifelong learning). We therefore studied the association between these human capital variables and social outcomes, and more specifically interpersonal trust and participation in volunteering activities. Results revealed that these social outcomes were affected not only by the formal qualification obtained, determined by the education variable, but also throughout the life‐cycle. Indeed, education and training when undertaken during adult life have a significant impact, especially on volunteering. The fact that the skill proficiency also plays a significant role is extremely relevant, as skills are more likely to change over the life‐cycle, either in a positive or negative way. Whilst the formal education received is constant after exiting the educational system, skills reflect competences more accurately: first, because those with the same level of education may have different skill levels because of differences in the quality of education or ability; second, because skills can vary over time. For example, they may increase with work experience or informal education, or decrease as a result of depreciation and ageing. These findings suggest that social outcomes are prone to be affected by many factors other than formal education, suggesting that policy makers can implement recommendations even after formal education has been completed.  相似文献

Adjustment scales for preschool intervention: Extending validity and relevance across multiple perspectives     

Rebecca Bulotsky‐Shearer  John Fantuzzo 《Psychology in the schools》2004,41(7):725-736

A series of studies extended psychometric research on the Adjustment Scales for Preschool Intervention (ASPI). The ASPI is a multidimensional measure of preschool emotional and behavioral adjustment for use within formal early childhood educational programs. These studies used a multiple method, multisource approach to provide additional evidence for the reliability and validity of the ASPI. Findings documented inter‐rater reliability of the ASPI across key informants within early childhood educational programs—teachers and teacher assistants. Findings supported concurrent validity of the ASPI with direct observations of preschool classroom adjustment problems and the developmentally salient constructs of temperament and emotion regulation. Implications for policy, practice, and future research are discussed. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 725–736, 2004.  相似文献   

The relationship between school belonging,sibling aggression and bullying involvement: implications for students with and without disabilities     

Chad A. Rose  Cynthia G. Simpson  Stephanie K. Ellis 《教育心理学》2016,36(8):1462-1486

Bullying is grounded in the interactions between an individual and complex social–ecological systems. Therefore, bullying involvement is not just confined to the classroom or school. Recent research suggests that sibling aggression may be a predictor for peer-level aggression. These findings may be more relevant for students with disabilities because studies suggest that students with disabilities are disproportionately involved in the bullying dynamic. Therefore, this study explored the intersection between sibling aggression and school belonging on bullying, victimisation and fighting for 14,508 students, including 1183 students with disabilities and 13,325 students without disabilities in grades 6 through 12. As hypothesised, students with disabilities reported higher levels of victimisation, bullying and fighting. Additionally, high levels of school belonging partially buffered fighting and bullying behaviours for students with and without disabilities. These findings demonstrate the importance of establishing an inclusive and safe environment for school-aged youth.  相似文献   

Development of system thinking skills in the context of earth system education   总被引：1，自引：0，他引：1

The current study deals with the development of system thinking skills at the junior high school level. The sample population included about 50 eighth‐grade students from two different classes of an urban Israeli junior high school who studied an earth systems‐based curriculum that focused on the hydro cycle. The study addressed the following research questions: (a) Could the students deal with complex systems?; (b) What has influenced the students' ability to deal with system perception?; and (c) What are the relationship among the cognitive components of system thinking? The research combined qualitative and quantitative methods and involved various research tools, which were implemented in order to collect the data concerning the students' knowledge and understanding before, during, and following the learning process. The findings indicated that the development of system thinking in the context of the earth systems consists of several sequential stages arranged in a hierarchical structure. The cognitive skills that are developed in each stage serve as the basis for the development of the next higher‐order thinking skills. The research showed that in spite of the minimal initial system thinking abilities of the students most of them made some meaningful progress in their system thinking skills, and a third of them reached the highest level of system thinking in the context of the hydro cycle. Two main factors were found to be the source of the differential progress of the students: (a) the students' individual cognitive abilities, and (b) their level of involvement in the knowledge integration activities during their inquiry‐based learning both indoors and outdoors. © 2005 Wiley Periodicals, Inc.  相似文献
