Maximum Dynamic Strength,Relative Dynamic Endurance,and Their Relationships     

Larry G. Shaver 《Research quarterly for exercise and sport》2013,84(4):460-465

Abstract

Nine males and nine females were used as subjects to test the null hypothesis that there would be no significant differences between the performance of college age males and females on three motor tasks. Star tracing, tapping, and rotary pursuit were the tasks used under two conditions: (a) while looking at a mirror that would cause a reversal effect, and (b) under standard conditions without looking at a mirror. Results revealed no differences between males and females on the tasks performed without a mirror. However, the females performed significantly better on the same tasks while looking at a mirror.  相似文献

To Catch a Liar: Challenges for Research in Lie Detection Training   总被引：1，自引：0，他引：1  

Mark G. Frank  Thomas Hugh Feeley 《Journal of Applied Communication Research》2003,31(1):58-75

Can we train people to detect deception? It is the contention of this article that communication scholars should learn how to train law enforcement professionals on how to detect high stake lies, like those faced by police, judges, customs officials, immigration officials, and so forth. It is proposed that in order to know whether we can train or should bother to train people to detect deception, each training study must meet 6 challenges: (1) relevance, (2) high stakes, (3) proper training, (4) proper testing, (5) generalizability across situations, and (6) generalizability over time. Our quantitative review of the literature suggests that training does significantly raise lie detection accuracy rates. Meta-analytic findings indicate a mean effect size of r = .20 across 20 (11 published studies) paired comparisons of lie detection training versus the control group (i.e., those without some type of training). It should be noted that the majority of the studies that attempt to train lie detectors fall short on many of the above challenges. Current research in lie detection training may actually underestimate the ability to train lie detectors due to the stimulus materials employed in most experiments.  相似文献   

STEM Is Elementary: Challenges Faced by Elementary Teachers in the Era of the Next Generation Science Standards     

Aaron D. Isabelle 《The Educational forum》2017,81(1):83-91

For students to achieve the goals of the Next Generation Science Standards (NGSS) by Grade 12, thinking and acting like scientists and engineers must begin in the elementary grades. However, elementary teachers may find this challenging -because language arts and mathematics still dominate many classrooms—often at the expense of science. This essay examines the science skills elementary students are expected to learn and how teachers and administrators can approach the increased demands of NGSS.  相似文献   

Effects of student-facilitated learning on instructional facilitators     

Sarah M. Bonner  Jennifer A. Somers  Gwendelyn J. Rivera  Leslie S. Keiler 《Instructional Science》2017,45(4):417-438

We investigated perceptions about learning strategy use and instructional roles among a sample of high needs adolescents (n = 230) who acted as near-peer instructional facilitators. The sample was drawn from science and mathematics classes in nonselective public secondary schools in New York City. Students participated in an inschool intervention that draws on social constructivism, theory and research on metacognition and learning strategies, role theory, and empirical findings from the peer-to-peer learning literature to promote advanced achievement among students who act as facilitators. Using a pre- and post-test single group design, we surveyed student instructional facilitators before and after program participation and related their perceptions about learning strategy use and perceptions about teaching roles to data about academic achievement. We found no survey gains in student perceptions about learning strategies or instructional roles between pre-survey (fall) and post-survey (spring). We found small but significant effects of individual perceptions about learning strategies and teaching roles on academic gains among instructional facilitators. The study also suggests that an in-school near-peer facilitated learning program can be an effective means to raise achievement in urban high schools. The study provides partial support for theories that hold that metacognition and role perceptions are involved in the academic gains of instructional facilitators, as gains in these dimensions were small compared to achievement gains.  相似文献   

Assessing the interrelatedness of multiple types of adverse childhood experiences and odds for poor health in South Carolina adults     

《Child abuse & neglect》2017

Adverse childhood experiences (ACEs) have been linked to negative health outcomes in adulthood, but little research has been done on the effect of ACEs on the health and well-being of adults in South Carolina (SC). This study analyzed a sample of 9744 respondents who participated in the 2014 South Carolina Behavioral Risk Factor Surveillance System (BRFSS) to examine the relationship among childhood experiences of physical, sexual, and emotional abuse, as well as witnessing household violence, on mental and physical health outcomes in adulthood among SC residents. Twenty-two percent of survey respondents reported poor general health (22.1%), and a smaller proportion reported high frequent mental distress in the past month (13.1%). Each category of childhood experiences was associated with an increase in the risk of poor general health. Individuals reporting three or more types of experiences were more likely to report poor health (aOR 2.89; 95% CI 2.86–2.92) than adults without such experiences. Respondents reporting three or more types of childhood adverse experiences were more likely to report frequent mental distress (aOR 3.29; 95% CI 3.26–3.33) compared to adults who did not report three or more types of adversity. Findings from the SC BRFSS highlight a connection between ACEs and negative health outcomes later in life. Given that results of this study also demonstrated that increased exposure to ACEs was associated with greater odds of negative health in adulthood, preventing adverse events such as experiencing abuse or witnessing domestic violence in childhood will have significant effects on later adult health.  相似文献   

Bernstein in the urban classroom: a case study     

Brian D. Barrett 《British Journal of Sociology of Education》2017,38(8):1258-1272

Despite a long-standing concern within the sociology of education for ameliorating educational inequality, the challenge of improving educational opportunities for disadvantaged students remains deeply entrenched. While ‘macro’ issues such as segregation and systemic inequalities in school funding and access to qualified teachers must be addressed as matters of social and educational justice, Basil Bernstein's novel focus on ‘relations within’ education as the site of pedagogic discourse offers teachers and those working inside school systems a particularly powerful vision for promoting more equitable outcomes for students. This paper examines this assertion through a case study of the ‘mixed’ pedagogical practice of a successful teacher in a fifth-grade urban classroom in the United States.  相似文献   

Integration and Physical Education: A Review of Research     

Risto Harri Juhani Marttinen  Gabriella McLoughlin  Ray Fredrick III  Dario Novak 《Quest (Human Kinetics)》2017,69(1):37-49

The Common Core State Standards Initiative has placed an increased focus on mathematics and English language arts. A relationship between physical activity and academic achievement is evident, but research on integration of academic subjects with physical education is still unclear. This literature review examined databases for the years 2004–2013, focusing on physical education or physical activity and core academic subjects for school-aged youth. 23 studies were found that focused on integration and physical education that met the inclusion criteria. These were from 16 different publication outlets, ranging in research methods, country, and population. This review provides information on the status of integration and physical education. Since classroom teachers are increasingly being encouraged to incorporate core subjects with physical activity into their classes, it would be appropriate for physical educators to understand the desired outcomes of integration of core subjects before attempting its implementation.  相似文献   

Further victimization of child sexual abuse victims: A latent class typology of re-victimization trajectories     

《Child abuse & neglect》2017

The association between child sexual abuse (CSA) and risk for re-victimization is well-documented; however, less is known about the temporal progression of re-victimization experiences over the early life-course among CSA survivors, and whether this differs from that of those without known sexual abuse histories. This study investigated whether there are distinct temporal pathways of interpersonal re-victimization between the ages of 10–25 years among medically confirmed CSA cases, and considered whether abuse variables, re-victimization variables, and the presence of other adverse outcomes, were associated with heterogeneity in re-victimization pathways. The data were collected as part of a large-scale data-linkage study in which the medical records of 2759 cases of contact-CSA between 1964 and 1995 were linked, between 13 and 44 years following abuse, to police and public psychiatric databases; cases were compared to a matched community sample (n = 2677). Using a subsample of 510 (401 victims; 109 comparisons) individuals with an interpersonal (re)victimization history, we examined the aggregate ‘age-(re)victimization’ curves for CSA victims and comparisons, respectively. Further, we applied longitudinal latent class analysis to explore heterogeneity in re-victimization trajectories among abuse survivors across their early life-course. Four latent pathways were identified, labeled: Normative; Childhood-Limited; Emerging-Adulthood; and Chronic re-victimization trajectories. Older age at abuse, a criminal history, and mental health problems were uniquely predictive of membership to the more problematic and persistent re-victimization trajectories. Findings indicate that individuals exposed to CSA during adolescence may be particularly vulnerable to poorer re-victimization trajectories, characterized by multiple risk indices, and thus may warrant increased service provision.  相似文献
