Proportionality Assumption in Latent Basis Curve Models: A Cautionary Note     

Wei Wu  Kyle M. Lang 《Structural equation modeling》2016,23(1):140-154

Latent basis curve models (LBCMs) have been popular in modeling change when the change trajectories are unknown or nonlinear. The estimated change trajectories from LBCMs are often viewed as optimal and used as reference points against which other change trajectories are tested. However, there is a proportionality assumption underlying LBCMs that has received little attention from researchers. This study uses a Monte Carlo simulation to show that violation of this assumption can potentially result in substantially biased estimates of the means and variances of changes and covariate effects on these changes, leading to incorrect statistical inference. The implications of the simulation study are discussed and alternatives to LBCMs are suggested for use when the proportionality assumption is likely to be violated.  相似文献

Walking backwards into the future: Indigenous wisdom within design education     

Nan O’Sullivan 《Educational Philosophy and Theory》2019,51(4):424-433

This research parallels Tongan academic Hūfanga ‘Okusitino Māhina’s assertions in the 1994 Contemporary Pacific article Our Sea of Islands, that ‘People are thought to walk forward into the past and walk backward into the future, both taking place in the present, where the past and the future are constantly mediated in the ever-transforming present’ alongside those of Professor Terry Irwin and fellow Transition Designers in which they discuss the use of Indigenous Wisdom to enable designing for the Long Now as defined by Brand in his 1999 book The Clock for the Long Now: Time and Responsibility. In the 2015 Transition Design Monograph Irwin asserts that, ‘Transition Design draws on knowledge and wisdom from the past to conceive solutions in the present with future generations in mind’. This paper draws on the pre-industrial wisdom of indigenous knowledge, specifically that of the Pacific regions, Moana, who have lived and designed sustainably in-place for generations to illustrate the value it holds for the formulation of sustainable and sustaining futures.  相似文献   

“‘I Was Gonna Go Off,but My Best Friend is White.”: Hispanic Students’ Co-Cultural Reasoning in a Hispanic Serving Institution     

Amy Aldridge Sanford  C. Kyle Rudick  Keith Nainby  Kathryn B. Golsan  Stephanie Rollie Rodriguez  Christopher J. Claus 《Communication quarterly》2019,67(2):158-177

The researchers engaged in a qualitative analysis (using journaling and focus group methodology) of the communicative behaviors of Hispanic students with White institutional members at a medium-sized, Southwest HSI. Utilizing Co-Cultural Theory and Elaborative Coding analysis, the authors mapped how Hispanic students narrated their co-cultural communication and reasoning (i.e., why they engage in one strategy rather than another). The findings show that, although Hispanic students used almost all co-cultural strategies, their responses were clustered primarily around assimilationist strategies – indicating that they engage in a high degree of self-monitoring and self-censorship when interacting with White institutional members in an HSI. These results suggest that even when Hispanic students constitute a large or majority part of the institution’s population, they still feel the need to engage in behaviors that navigate White norms. The study concludes by examining the findings for co-cultural theorizing as well as providing insights for instructors who wish to engage in inclusive teaching practices.  相似文献   

Tensiomyographical responses to accelerometer loads in female collegiate basketball players     

Kyle D. Peterson  Gabriela T. Quiggle 《Journal of sports sciences》2017,35(23):2334-2341

The purpose of the present study was to characterise the relationship between relative versus absolute internal and external loads in collegiate basketball players throughout the course of a season. Five Division I basketball players wore triaxial accelerometers throughout the 2015–2016 season and were tensiomyographically assessed weekly. One-way repeated-measure analysis of variance (RM ANOVA) with least-significant-difference (LSD) pairwise comparisons was used to determine which absolute weekly loads were different across the season. Cohen’s d was used to supplement the determination of meaningful relative load changes. Overall RM ANOVA models suggest absolute external load differences occurred (PlayerLoad? F = 17.63; IMA? F = 31.63). Two-way RM ANOVA models revealed main effect differences were revealed between muscle groups for Tc (F = 9.11) and Dm (F = 3.25). Meaningful relative load changes between weeks were observed for both external and internal. The present study observed that tensiomyography utilised as a tool to monitor internal load may be more suitable for detecting fatigue from relative external load changes versus absolute load attained. Limiting weekly training volume changes to ≤10% may maintain appropriate adaptation. Mediolateral plane IMA? and adductor longus muscle group may be pertinent metrics when monitoring female collegiate basketball athletes.  相似文献   

Increasing hip and knee flexion during a drop-jump task reduces tibiofemoral shear and compressive forces: implications for ACL injury prevention training     

Liang-Ching Tsai  Yi-An Ko  Kyle E. Hammond  John W. Xerogeanes  Gordon L. Warren  Christopher M. Powers 《Journal of sports sciences》2017,35(24):2405-2411

Although most ACL injury prevention programmes encourage greater hip and knee flexion during landing, it remains unknown how this technique influences tibiofemoral joint forces. We examined whether a landing strategy utilising greater hip and knee flexion decreases tibiofemoral anterior shear and compression. Twelve healthy women (25.9 ± 3.5 years) performed a drop-jump task before and after a training session (10–15 min) that emphasised greater hip and knee flexion. Peak tibiofemoral anterior shear and compressive forces were calculated using an electromyography (EMG)-driven knee model that incorporated joint kinematics, EMG and participant-specific muscle volumes and patella tendon orientation measured using magnetic resonance imaging (MRI). Participants demonstrated a decrease in peak anterior tibial shear forces (11.1 ± 3.3 vs. 9.6 ± 2.7 N · kg^?1; P = 0.008) and peak tibiofemoral compressive forces (68.4 ± 7.6 vs. 62.0 ± 5.5 N · kg^?1; P = 0.015) post-training. The decreased peak anterior tibial shear was accompanied by a decrease in the quadriceps anterior shear force, while the decreased peak compressive force was accompanied by decreased ground reaction force and hamstring forces. Our data provide justification for injury prevention programmes that encourage greater hip and knee flexion during landing to reduce tibiofemoral joint loading.  相似文献   

Join the Club: Food Advertising, 1930s Children's Popular Culture,and Brand Socialization     

Kyle Asquith 《Popular Communication》2014,12(1):17-31

Relying upon archival research, this article examines children's food advertising during the 1930s. More specifically, I highlight advertiser-created “clubs.” As a complement to 1930s radio and comic strip sponsorships, dozens of national food brands introduced “clubs” for children. Through a series of case studies, I argue that by creating these clubs, national food advertisers embedded themselves in children's popular culture with the outcome of brand socialization—not simply immediate sales. These clubs offered access to exclusive branded communities, encouraging children to be brand-conscious and brand-loyal consumers. Unlike toy advertisers, who did not enter children's popular culture until the television era, food advertisers sold products meant to be consumed daily; as such, brand loyalty was highly sought after.  相似文献   

Cognitive development of intellectually gifted: A Piagetian perspective     

Kyle R. Carter 《Roeper Review》2013,35(3):180-184

This article explores some of the materials prepared for parents of gifted children and examines the explanatory language and concepts used in terms of their potential for shaping parental attitudes and affecting the adjustment of gifted children. The author argues that the conceptual frameworks used to explain giftedness, nongiftedness and the nature of differences have powerful effects on societal and educational attitudes, including the willingness to provide differentiated services for gifted children. A strong plea is made for professional sensitivity and responsibility in describing giftedness in ways that do not isolate gifted children or their parents and which potentiate shared advocacy with other educational advocacy groups.  相似文献
