Ni de Aquí, Ni de Allá: Conceptualizing the self-authorship experience of gay Latino college men using conocimiento     

Roberto C. Orozco  Lara Perez-Felkner 《Journal of Latinos & Education》2018,17(4):386-394

This essay aims to enhance our conceptual understanding of students with intersectional identities, specifically gay Latino men in college. We first explain how ethnic, gender, and sexual identities can act as compounding influences. Second, we review two distinct but complementary developmental theories. Conocimiento captures the disruptive, challenging path experienced by marginalized Latino youth. Self-authorship situates the broader developmental process in and beyond college. Our modified framework—conociéndose y escribiéndose—conceptualizes how college students navigate multiple marginalized identities. Finally, we discuss the implications of this intersectional framework for LGBTQ+ students and institutions seeking to enhance diversity, inclusion, and student success.  相似文献   

Teaching the Use of Library of Congress Subject Headings as a Research Strategy for Undergraduate Students     

Debra Spidal  Lara Ursin Cummings 《College & Undergraduate Libraries》2014,21(2):155-176

Library of Congress subject headings (LCSH) are such a powerful tool that ACRL recognized them in the Information Literacy Competency Standards. The Standards state that the information-literate student should be able to select discipline-specific controlled vocabulary and construct a search strategy. The authors, recognizing this often-forgotten Standard, surveyed instruction librarians to determine if LCSH are still taught in the library instruction classroom, and, if so, which strategies are used for identifying relevant subject headings. Survey results were mixed. While teaching the use of controlled vocabulary has clearly fallen from popularity, it is still recognized as a valuable tool.  相似文献   

Determination of football pitch locations from video footage and official pitch markings     

Alison Alcock  Adam Hunter  Nicholas Brown 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(2):129-140

The ability to determine a specific location on a football (soccer) pitch from television footage would provide a cost-effective method of obtaining competition-specific information on many professional and international teams. This study presents the accuracy and reliability of a new method of calculating ball location from simulated television coverage and known pitch markings. The coordinates of 99 markers of known location on a football pitch were digitized from video. An intersection point was determined from the equations of two lines that form pitch markings and the relationship from this point to other known pitch coordinates was calculated using a curve-fitting based method. Average error between known and reconstructed measures was 0.21 m for pitch width and 0.11 m for pitch length from a view simulating television coverage. Inter- and intra-rater reliability analyses showed researchers could consistently reconstruct pitch locations to within less than half a metre. The accuracy and reliability of this method will be sufficient for most practical uses in an applied sport environment, although the level of accuracy required will depend on the specific application. This method could be applied to other sports to determine specific locations on a pitch or court or to improve current competition analysis systems.  相似文献   

Effects of added elastic tubes on open-chain knee extensor strength training

Attaching elastic tubes (ETs) to resistance training machines can affect the exercise load profile. The purpose of this study was to assess the training effects of added ETs, which were strategically attached to provide additional loads only during the deceleration phase of the knee extension exercise. Twenty-two healthy participants, assigned to either an experimental group (with ETs) or a control group (without ETs), participated in a 12-week strength-training program using a knee extension exercise machine. The acceleration effects were quantified and a method of attaching the ETs to the knee extension machine was developed. The effects of the added ETs were analysed by testing dynamic and isometric maximum contractions at four knee flexion angles (10°, 30°, 50°, and 80°). Analyses of covariance with the initial values as the covariate were used to examine the ET effects. A greater increase in isometric maximum strength was found in the experimental group than in the control group at knee flexion angles of 10° [effect size (ES) = 2.25] and 30° (ES = 1.18). No significant difference in the dynamic maximum strength was found between the groups. The use of ETs increased strength at smaller knee flexion angles with quadriceps that were relatively short.  相似文献   

Profiles of learning opportunities of multilingual and monolingual children in kindergarten     

Langeloo  Annegien  Lara  Mayra Mascareño  Deunk  Marjolein I.  LoCasale-Crouch  Jennifer  Strijbos  Jan-Willem 《European Journal of Psychology of Education - EJPE》2021,36(2):379-404

Early childhood education serves an increasing number of multilingual children, and teachers are challenged to create high-quality learning opportunities in the classroom for all children. The child’s engagement and interactions with the teacher are important in this respect. The present study therefore examined how multilingualism relates to engagement and teacher-child interactions, taking a person-oriented approach. During one school year, 76 kindergarteners (43 multilingual) from 19 classrooms were observed for behavioral engagement and individual teacher-child interactions. Five engagement profiles were identified that reflect different levels of engagement across classroom settings. Multilingual children were overrepresented in profiles that showed lower engagement in one or more settings. Also, five interaction profiles were identified that showed strong diversity in the interactions of teachers with children in their classroom. Monolingual and multilingual children were equally represented across these profiles. Children in the more beneficial interaction profiles were also often in the moderate-to-high engagement profiles.

Alternative strategy to decrease cesarean section: support by doulas during labor          下载免费PDF全文

Trueba G  Contreras C  Velazco MT  Lara EG  Martínez HB 《The Journal of perinatal education》2000,9(2):8-13

This research was conducted in a public general hospital in Mexico City, Mexico. The objective was to evaluate efficacy of the support given by a doula during labor to reduce cesarean rate. From March 1997 to February 1998, a group of 100 pregnant women were studied. These women were at term, engaged in an active phase of labor, exhibited 3 cm. or more cervical dilatation, were nuliparous, had no previous uterine incision, and possessed adequate pelvises. The group was randomly divided into two subgroups comprising 50 women, each: The first subgroup had the support of a childbirth educator trained as a doula, while the second subgroup did not have doula support. Measurements were recorded on the duration of labor, the use of pitocin, and whether or not the birth was a vaginal birth or cesarean section. Characteristics and gestational age were similar in both groups. Results confirmed that support by doulas during labor was associated with a significant reduction in cesarean birth and pitocin administration. There was a trend toward shorter labors and less use of epidurals. The results of this study showed, as in other trials measuring the impact of a doula's presence during labor and birth, that doula support during labor is associated with positive outcomes that have physical, emotional, and economic implications.  相似文献
