Despite the many benefits of involving undergraduates in research and the growing number of undergraduate research programs,
few scholars have investigated the factors that affect faculty members’ decisions to involve undergraduates in their research
projects. We investigated the individual factors and institutional contexts that predict faculty members’ likelihood of engaging
undergraduates in their research project(s). Using data from the Higher Education Research Institute’s 2007–2008 Faculty Survey,
we employ hierarchical generalized linear modeling to analyze data from 4,832 science, technology, engineering, and mathematics
(STEM) faculty across 194 institutions to examine how organizational citizenship behavior theory and social exchange theory
relate to mentoring students in research. Key findings show that faculty who work in the life sciences and those who receive
government funding for their research are more likely to involve undergraduates in their research project(s). In addition,
faculty at liberal arts or historically Black colleges are significantly more likely to involve undergraduate students in
research. Implications for advancing undergraduate research opportunities are discussed. 相似文献

We compared cardiorespiratory responses to exercise on an underwater treadmill (UTM) and land treadmill (LTM) and derived an equation to estimate oxygen consumption (VO2) during UTM exercise. Fifty-five men and women completed one LTM and five UTM exercise sessions on separate days. The UTM sessions consisted of chest-deep immersion, with 0, 25, 50, 75, and 100% water-jet resistance. All session treadmill velocities increased every 3 min from 53.6 to 187.8 m x min(-1). Cardiorespiratory responses were similar between LTM and UTM when jet resistance for UTM was 50%. Using multiple regression analysis, weight-relative VO2 could be estimated as: VO2 (mLO2 c kg(-1) x min(-1)) = 0.19248 x height (cm) + 0.17422 x jet resistance (% max) + 0.14092 x velocity (m x min(-1)) -0.12794 x weight (kg)-27.82849, R2 = .82. Our data indicate that similar LTM and UTM cardiorespiratory responses are achievable, and we provide a reasonable estimate of UTM VO2. 相似文献

All women should be allowed and encouraged to bring a loved one, friend, or doula to their birth without financial or cultural barriers. Continuous labor support offers benefits to mothers and their babies with no known harm. This article is an updated evidence-based review of the “Lamaze International Care Practices that Promote Normal Birth, Care Practice #3: Continuous Labor Support,” published in The Journal of Perinatal Education, 16(3), 2007. 相似文献

Three vocational high schools provide illustrative and contrasting histories in terms of African-American education and economic opportunity. Washburne Trade School reinforced trade union exclusion of African-Americans, and since integration in the 1960s has been abandoned by most of the powerful unions. Dunbar Vocational High School directed African-Americans into the lower-paying trades, but has lost the economic base that the ghetto once provided. Chicago Vocational School prepared the white working class for industrial jobs, but integration and re-segregation has coincidentally seen the erosion of Chicago's manufacturing base. These schools are compared in the economic, political, and cultural contexts of past and present. It is proposed that an integrated strategy for the reform of vocational education is necessary for these schools to adapt to economic change in the present and future. 相似文献

Why is comparability of forms important for performance assessments? Can traditional methods of form equating be used? What problems are likely to arise in equating? Can standards generalize across forms? 相似文献

Elite rugby union teams currently employ the latest technology to monitor and evaluate the physical demands of training and games on their players. Tackling has been shown to be the most common cause of injury in rugby union, yet current player monitoring technology does not effectively evaluate player tackling measurements. Currently, to evaluate measurements specific to player tackles, a time-consuming manual analysis of player sensor data and video footage is required. The purpose of this work is to investigate tackle modeling techniques which can be utilised to automatically detect player tackles and collisions using sensing technology already being used by elite international and club level rugby union teams. This paper discusses issues relevant to automatic tackle analysis, describes a technique to detect tackles using sensing data and validates the technique by comparing automatically detected collisions to manually labeled collisions using data from elite club and international level players. The results of the validation show that the system is able to consistently identify collisions with very few false positives and false negatives, achieving a recall and precision rating of 0.933 and 0.958, respectively. The aim is that the automatically detected tackles can provide coaching, medical and strength and conditioning staff with objective tackle-specific measurements, in real time, which can be used in injury prevention and rehabilitation strategies. 相似文献

Effectiveness of Spanish intervention for first-grade English language learners at risk for reading difficulties 总被引:1,自引:0,他引:1

The effectiveness of an explicit, systematic reading intervention for first-grade students whose home language was Spanish and who were at risk for reading difficulties was examined. Participants were 69 students in 20 classrooms in 7 schools from 3 districts who initially did not pass the screening in Spanish and were randomly assigned within schools to a treatment or comparison group; after 7 months, 64 students remained in the study. The intervention matched the language of instruction of their core reading program (Spanish). Treatment groups of 3 to 5 students met daily for 50 min and were provided systematic and explicit instruction in oral language and reading by trained bilingual intervention teachers. Comparison students received the school's standard intervention for struggling readers. Observations during core reading instruction provided information about the reading instruction and language use of the teachers. There were no differences between the treatment and comparison groups in either Spanish or English on any measures at pretest, but there were significant posttest differences in favor of the treatment group for the following outcomes in Spanish: Letter-Sound Identification (d = 0.72), Phonological Awareness composite (d = 0.73), Woodcock Language Proficiency Battery-Revised Oral Language composite (d = 0.35), Word Attack (d = 0.85), Passage Comprehension (d = 0.55), and two measures of reading fluency (d = 0.58-0.75). 相似文献

Seventy‐seven new academics – 59 at a large, public university in the UK and 18 at a medium‐sized, private comprehensive university in the USA – were asked to read an extract of an article on the scholarship of teaching and learning (SoTL) and mark the text according to categories of difficulty or dislike. Analysis of the data revealed six main linguistic barriers in the text: specialist vocabulary, passive constructions, pronouns, figurative language, derivations and poor editorial standards. These barriers were similar at both institutions, suggesting they apply across different contexts. Contrary to expectations, no conclusive disciplinary‐based distinctions were detected. Implications for both readers and writers are explored and proposals are made for developing a literary style in SoTL literature that is simultaneously accessible and credible. Soixante‐dix‐sept nouveaux enseignants – cinquante‐neuf provenant d’une université publique britannique de grande taille et dix‐huit provenant d’une université privée américaine de taille moyenne – ont lu l’extrait d’un article portant sur le scholarship of teaching and learning (SoTL) et ont identifié les parties qu’ils jugeaient difficiles ou qu’ils n’appréciaient pas. Une analyse des données révèle la présence de six barrières linguistiques principales dans le texte: le vocabulaire spécialisé, les constructions passives, les pronoms, le langage figuratif, les dérivations et des standards de rédaction de piètre qualité. Ces barrières étaient similaires dans le cas des deux institutions, ce qui suggère qu’elles sont applicables dans des contextes différents. Contrairement aux attentes, aucune distinction reposant sur les disciplines permettant de tirer des conclusions n’a pu être détectée. Les implications pour les lecteurs et les rédacteurs sont explorées et des propositions visant à développer un style littéraire pour la documentation portant sur le SoTL qui soit à la fois accessible et crédible sont formulées. 相似文献
