The aim of this study is to determine changes in sedentary behaviour in response to extensive aerobic exercise training. Participants included adults who self-selected to run a marathon. Sedentary behaviour, total activity counts and physical activity (PA) intensity were assessed (Actigraph GT3X) for seven consecutive days during seven assessment periods (?3, ?2, and ?1 month prior to the marathon, within 2 weeks of the marathon, and +1, +2, and +3 months after the marathon). Models were fitted with multiple imputation data using the STATA mi module. Random intercept generalized least squares (GLS) regression models were used to determine change in sedentary behaviour with seven waves of repeated measures. Results: Twenty-three individuals (mean?±?S_x: 34.4?±?2.1y, 23.0?±?1.9% fat, 15 women, 8 men) completed the study. Marathon finishing times ranged from 185 to 344 minutes (253.2?±?9.6 minutes). Total counts in the vertical axis were 1,729,414 lower one month after the race, compared with two months prior to the race (peak training). Furthermore, counts per minute decreased by 252.7 counts·minute^?1 during that same time period. Daily sedentary behaviour did not change over the seven assessment periods, after accounting for age, gender, per cent body fat, wear time, marathon finishing time, and previous marathon experience. This prospective study supports the notion that PA and sedentary behaviours are distinct, showing that sedentary behaviour was not impacted by high levels of aerobic training.  相似文献   

Mental illness on television: A study of censorship     

George Gerbner 《广播与电子媒介杂志》2013,57(4):293-303

This study was part of a larger project directed by C. E. Osgood and J. C. Nunally of the University of Illinois, conducted under a grant from the National Institute of Mental Health. It is especially interesting, not only because of the current controversy over television program control, but for the light it throws on the operation of the network departments charged with the censorship function.  相似文献   

Science textbooks for lower secondary schools in Brunei: issues of gender equity     

Ann G. Elgar 《International Journal of Science Education》2013,35(7):875-894

This paper is concerned with issues affecting equity in science education for girls and boys. In the paper the results of an investigation into the recently published (1998–2000) series of textbooks entitled Lower Secondary Science for Brunei Darussalam are presented. In the first part of the paper, background issues of continuing gender inequality in science education and of the nature and scope of textbook analyses are outlined. Then the representation of males and females in both illustrations and text in the Bruneian textbooks is discussed. From this analysis a picture emerges of the extent to which science is portrayed as a pursuit of equal appropriateness for both boys and girls. The paper concludes with a consideration of the implications of the findings presented within the wider context of gender and education in Brunei.  相似文献   

Assessment in special schools: national early assessment procedures and pupils attending special schools in England     

Ann Lewis  Geoff Lindsay  Emma Phillips 《欧洲特需教育杂志》2013,28(2):141-153

An implicit assumption that fostering inclusion means having shared systems encompassing the needs of all children is evident in many aspects of policy development over the past decade. Reflecting this, the implementation of ‘baseline assessment’ schemes (i.e. testing at around age 5 years) is a statutory requirement on all state-maintained special and mainstream schools in England since 1998. Our argument is that the enthusiasm for commonality has obscured the need to question the value and validity of baseline assessment schemes for children with special educational needs (and possibly some others such as children having English as an additional language). We illustrate this position with reference to data from our recent study on baseline assessment in England. The study encompassed survey data from a national sample of 982 schools, of which 107 were special schools. Between them, these special schools used 42 different baseline assessment schemes. Comparisons between our mainstream and special school respondents indicated that there were similarities in the nature and perceived value of the schemes used. However, special schools were less satisfied with their schemes. We suggest that a reappraisal of the nature and purpose of baseline assessment for pupils with special educational needs warrants greater critical debate. Without this, there is a danger that a stress on commonality, veiling an inclusion orthodoxy, will ultimately be counterproductive.  相似文献

The Combined Effects of Instructor Communicative Behaviors,Instructor Credibility,and Student Personality Traits on Incivility in the College Classroom     

Brian Klebig  Joanna Goldonowicz  Elisa Mendes  Ann Neville Miller  James Katt 《Communication Research Reports》2016,33(2):152-158

This study investigated the combined role of instructor communication variables (nonverbal immediacy and self-disclosure), instructor credibility (competence, caring, and trustworthiness), and student personality traits (extraversion, neuroticism, agreeableness, conscientiousness, and openness) in predicting students’ uncivil behaviors in class. A total of 406 students completed online questionnaires regarding the instructor of the class they attended prior to the one in which the study was administered. Personality and instructor behavior variables contributed approximately equally to explaining variance in student incivility. Students’ conscientiousness and agreeableness had direct negative relationships with incivility, whereas instructors’ amount and negativity of self-disclosure had direct positive relationships with incivility.  相似文献   

The Peril of Ignoring Middle School Student Speech Rights     

Ann Hassenpflug 《Clearing house (Menasha, Wis.)》2016,89(1):23-27

Analysis of two recent federal court cases in which principals violated student speech rights offers guidance to middle school administrators as they attempt to address student expression. Characteristics of a successful school from the Association for Middle Level Education provide a framework for analyzing these cases in order to prevent potential violations of First Amendment speech rights of students.  相似文献   

Validity of Self-Reported Pedometer Steps per Day in College Students     

Brittany Star Overstreet  Scott E. Crouter  George A. Butler  Cary M. Springer  David R. Bassett 《Measurement in physical education and exercise science》2016,20(3):140-145

The purpose of this article was to examine the validity of self-reported pedometer steps/day. Forty-seven participants were provided a New Lifestyles NL-2000 (NL-2000; Lees Summit, MO, USA) pedometer and a physical activity (PA) diary for 3 weeks, but not informed of the data-storing capabilities. For weeks 2 and 3, each participant was given a step goal of 3,000 steps/day above week 1 average. A 2 × 3 repeated measures analysis of variance (ANOVA) was used to examine differences between reported steps/day. Bland–Altman plots assessed the mean bias and limits of agreement between reporting methods. Mean self-reported and NL-2000 steps/day were 9,264 ± 3,555 and 8,971 ± 3,590 steps/day (n = 26, p > .05). Mean biases were 216 ± 1,753 (week 1), –506 ± 1,355 (week 2), and –590 ± 1,360 (week 3) steps/day. Negative mean bias values indicate higher self-reported steps/day. Mean steps/day were similar between recording methods, but large differences were observed among individuals, suggesting self-reported steps/day may be valid for PA research at the population level, but not the individual level.  相似文献   

Mapping the literature of hospital pharmacy     

Ann Barrett  Melissa Helwig  Karen Neves 《Journal of the Medical Library Association》2016,104(2):118-124

Objectives

This study describes the literature of hospital pharmacy and identifies the journals most commonly cited by authors in the field, the publication types most frequently cited, the age of citations, and the indexing access to core journals. The study also looks at differing citation practices between journals with a wide audience compared to a national journal with a focus on regional issues and trends in the field.

Method

Cited references from five discipline-specific source journals were collected and analyzed for publication type and age. Two sets were created for comparison. Bradford''s Law of Scattering was applied to both sets to determine the most frequently cited journals.

Results

Three-quarters of all cited items were published within the last 10 years (71%), and journal articles were the most heavily cited publication type (n=65,760, 87%). Citation analysis revealed 26 journal titles in Zone 1, 177 journal titles in Zone 2, and the remaining were scattered across 3,886 titles. Analysis of a national journal revealed Zone 1 comprised 9 titles. Comparison of the 2 sets revealed that Zone 1 titles overlapped, with the exception of 2 titles that were geographically focused in the national title.

Conclusion

Hospital pharmacy literature draws heavily from its own discipline-specific sources but equally from core general and specialty medical journals. Indexing of cited journals is complete in PubMed and EMBASE but lacking in International Pharmaceutical Abstracts. Gray literature is a significant information source in the field.  相似文献   

X marks the spot: Creating and managing a single service point to improve customer service and maximize resources     

Mary Ann Venner 《Journal Of Access Services》2016,13(2):101-111

ABSTRACT

This article will describe how merging service points in an academic library is an opportunity to improve customer service and utilize staffing resources more efficiently. Combining service points provides libraries with the ability to create a more positive library experience for patrons by minimizing the ping-pong effect for assistance. The Access Services Department at the University of North Texas Libraries was charged with management of the circulation and reference services offered at the service desk. Streamlined planning and modernized management of the desk and its impact on customer service in a changing library environment will be discussed.  相似文献
