Using cross-sectional data from the 2008 National Annenberg Election Survey, this study tests 2 models that explicate the relationship between politically likeminded media use and political polarization and participation. The knowledge model suggests that the effects of exposure to likeminded media on individuals’ attitudinal polarization and political participation are mediated by knowledge of candidate issue stances. The belief model proposes that likeminded media use indirectly influences political polarization and participation via political beliefs. The results provide evidence that individuals’ beliefs mediate the influence of likeminded media consumption on attitudinal polarization and participation, but there was no support for the knowledge model. These findings indicate that individuals who consume politically likeminded news tend to develop polarized attitudes and are motivated to participate in political activities by forming biased beliefs associated with candidates rather than by gaining factual issue knowledge. 相似文献

This study identified coparenting patterns using data collected across 2007–2010 from low-income couples (N = 2915; 26.90% non-Hispanic White; 9.41% non-Hispanic Black; 34.24% Hispanic, 29.27% other or mixed race) with young children (M = 3.65 years; SD = 1.31 years; 48% girls) and examined relations with children's social–emotional adjustment. Latent profile analysis revealed four coparenting patterns: mutual high-quality (43.4%), moderate-quality, mothers less positive (31.8%), moderate-quality, fathers less positive (15.9%), and low-quality, mothers less positive (8.9%). When parents' perspectives on coparenting were positive and congruent, children fared best. Children also fared well when coparenting quality was moderate, and mothers were less positive than fathers. When coparenting quality was moderate and fathers were less positive than mothers, children showed the poorest adjustment. 相似文献

Efficient management of toxicity information as an enterprise asset is increasingly important for the chemical, pharmaceutical, cosmetics and food industries. Many organisations focus on better information organisation and reuse, in an attempt to reduce the costs of testing and manufacturing in the product development phase. Toxicity information is extracted not only from toxicity data but also from predictive models. Accurate and appropriately shared models can bring a number of benefits if we are able to make effective use of existing expertise. Although usage of existing models may provide high-impact insights into the relationships between chemical attributes and specific toxicological effects, they can also be a source of risk for incorrect decisions. Thus, there is a need to provide a framework for efficient model management. To address this gap, this paper introduces a concept of model governance, that is based upon data governance principles. We extend the data governance processes by adding procedures that allow the evaluation of model use and governance for enterprise purposes. The core aspect of model governance is model representation. We propose six rules that form the basis of a model representation schema, called Minimum Information About a QSAR Model Representation (MIAQMR). As a proof-of-concept of our model governance framework we develop a web application called Model and Data Farm (MADFARM), in which models are described by the MIAQMR-ML markup language. 相似文献

This study investigated the effectiveness of a guided inquiry integrated with technology, in terms of female middle-school
students’ attitudes toward science/scientists and content knowledge regarding selective science concepts (e.g., Greenhouse
Effect, Air/Water Quality, Alternative Energy, and Human Health). Thirty-five female students who were entering eighth grade
attended an intensive, 1-week Inquiry-Based Science and Technology Enrichment Program which used a main theme, “Green Earth
Enhanced with Inquiry and Technology.” We used pre- and post-attitude surveys, pre- and post-science content knowledge tests,
and selective interviews to collect data and measure changes in students’ attitudes and content knowledge. The study results
indicated that at the post-intervention measures, participants significantly improved their attitudes toward science and science-related
careers and increased their content knowledge of selected science concepts (p < .05). 相似文献

ABSTRACTWhen new protocols are developed, there is a requirement to investigate test–retest reliability of measures for valid use and interpretation of data in research and practice. Therefore, the aim of this investigation was to determine the inter-day reliability of the cable put and seated rotation assessment protocols. On three occasions, nine resistance-trained men performed cable puts and cable rotations at different loads between 6 and 42 kg on a commercially available cable cross over machine. Load stack movement was recorded using a PT5A linear position transducer from which all kinematic and kinetic variables were calculated. Reliability was excellent for peak velocity and displacement based on intraclass correlation coefficient (ICC) and coefficient of variation (CV) across the majority of loads and movements (cable put: ICC = 0.92 to 0.99, CV = 3.1% to 8.6%; cable seated rotation: ICC = 0.76 to 0.99, CV = ?1.7% to 16.1%). However, kinetic variables demonstrated inadequate reliability across the majority of days, loads and movements (ICC = 0.70, CV >10%). It was concluded that peak velocity is a reliable kinematic measure to assess muscular capability from cable put and seated rotation protocols; however, kinetic measures are too variable to provide reliable outputs across testing occasions. 相似文献

ABSTRACTThis paper proposes to use inter-Asian methodologies to reread Asian Canadian Studies. As an intellectual and political project, Asian Canadian Studies has largely been constituted through its responses to the Canadian nation-state and anti-racism alliances but has failed to seriously engage with Asia as a critical problematic. Informed by theories and practices of inter-referencing developed through Inter-Asia critique, we reconsider the specific pressures, local debates, and historical moments that have produced the field's central arguments and reframe the field as a series of localized reference points in dialogue with each other as well as with Asia. We conclude by turning to Madeleine Thien's novel Dogs at the Perimeter in order to ask what it might mean to localize Asian Canadian Studies and reposition it as part of a transpacific rather than nation-based formation. 相似文献

ABSTRACT Cross-country skiing is a complex endurance sport requiring technical skills, in addition to considerable physiological and tactical abilities. This review aims to identify biomechanical factors that influence the performance of cross-country skiers. Four electronic databases were searched systematically for original articles in peer-reviewed journals addressing the relationship between biomechanical factors (including kinematics, kinetics, and muscle activation) and performance while skiing on snow or roller skiing. Of the 46 articles included, 22 focused exclusively on the classical technique, 18 on the skating technique, and six on both. The indicators of performance were: results from actual or simulated races (9 articles); speed on specific tracts (6 articles); maximal or peak speed (11 articles); skiing economy or efficiency (11 articles); and grouping on the basis of performance or level of skill (12 articles). The main findings were that i) cycle length, most often considered as a major determinant of skiing speed, is also related to skiing economy and level of performance; ii) higher cycle rate related with maximal speed capacity, while self-selected cycle rate improves skiing economy at sub-maximal speeds; iii) cross-country skiing performance appears to be improved by joint, whole-body, ski, and pole kinematics that promote forward propulsion while minimizing unnecessary movement. 相似文献

This study attempts to elucidate the idea that education reflects the contemporary social structure. This inference is focused
on the educational struggle for Korean identity led by the Korean Federation in Japan (KFJ) during 1945– 1948. The KFJ disseminated
the educational movement for Koreans in Japan (Zainichi). The General Head Quarters (GHQ) suppressed Korean identity education
(KIE) and tried to disrupt the activities of the KFJ. KIE was identified and destroyed during the HanShin educational struggle
as part of the conflict with the GHQ. However, HanShin movement survived to form the basis for the new start of the Korean
educational movement in Japan and has served as the cornerstone of KIE. This case elucidates the ways in which education is
strongly associated with the social structure and the status quo. 相似文献

The aim of the study is to compare longitudinal patterns from Mathematics and Reading data from the direct child assessment
of Early Child Longitudinal Study, Kindergarten (ECLS-K, US Department of Education, National Center for Education Statistics
2006), utilizing Profile Analysis via Multidimensional Scaling (PAMS). PAMS has been used initially to discover profile patterns
in crosssectional data, and further applied to uncover longitudinal patterns by considering each time point as a coordinate
of longitudinal patterns. The ECLS-K data analyzed here included longitudinal information about student achievement. The current
study applied longitudinal PAMS to the data and examined how much the longitudinal patterns predict the fifth-grade achievement
scores. Results showed that the longitudinal patterns that depicted the growing trend and the growing–decaying trend were
significantly related to the fifth-grade achievement scores. Educational implications and discussions of longitudinal patterns
were included. 相似文献
