Adductor longus mechanics during the maximal effort soccer kick

Groin pain is a common cause of athletic disability and often involves the adductor longus. A common complaint of patients with groin problems is pain while preparing to kick the ball. The purpose of this study was to examine muscle length and activation of the adductor longus while kicking a soccer ball. Three-dimensional joint positions and muscle activation were obtained from 15 National Collegiate Athletic Association (NCAA) Division 1 male soccer players during maximal effort kicks. Musculoskeletal modeling techniques incorporating joint position and muscle attachments were used to estimate adductor longus length from the beginning of the kicking leg's swing phase until ball strike. The maximum rate of stretch of the adductor longus (22.3 ± 5.3 cm/s) and maximum hip extension (23.3 ± 8.8°) occurred near 40% of swing phase. Activation of the adductor longus occurred between 10% and 50% of the swing phase. Adductor longus maximum length occurred at 65% of the swing phase. Maximum hip abduction (25.3 ± 5.4°) occurred at 80% of swing phase. The adductor longus appears to be at risk of strain injury during its transition from hip extension to hip flexion. This knowledge could be applied to muscle injury prevention and rehabilitation programs to aid with treatment of adductor longus related groin pain.     

Movies in Public Libraries: A Checklist Comparison with Internet Movie Database Recommendations

This research compares the fifty top-rated movies for 2000–2009 recommended by the Internet Movie Database (IMDb) with the holdings of ten medium-sized public libraries. The study shows that there was no relation between a movie's rank in the IMDb listing and the number of copies held. Relationships appeared between number of library holdings and country of production (U.S. productions favored), genre (family, sci-fi, animation, adventure favored), and Motion Picture Association of America (MPAA) rating (G, PG, PG-13 preferred). Library holdings seem to reflect preferences of IMDb raters aged 30 and older, not popular movie tastes.

Exploratory Factor Analysis (EFA) Programs in R

We provide a brief overview of two R packages that can conduct exploratory factor analysis (EFA): psych and EFAutilities. After introducing EFA and the exemplar data used in this paper we discuss best practices for EFA. Next, we describe the approaches used in the two packages for EFA. During this explanation, we provide sample code and discuss the usage and results of two empirical datasets. Finally, we highlight the similarities and distinctions of each package on modeling EFA.     

The Longitudinal Associations Among Temperament,Parenting, and Turkish Children's Prosocial Behaviors

In Turkey, responsive behaviors toward kin are expected from children. Despite this, we know little about the factors that influence young Turkish children's prosocial behaviors. The goal was to explore how temperament and parenting are related to children's prosocial development in Turkey. A total of 293 Turkish children (M_age = 49 months; 48.12% females) were followed up for 3 years. Mothers completed measures of their child's prosocial behaviors, as well as measures of their warmth, inductive reasoning, and the child's approach and reactivity. Maternal warmth predicted children's reactivity, and maternal induction predicted children's sociability. Children's reactivity was inversely related to children's helping behavior and sociability was related to more prosocial behavior. Maternal warmth had indirect links with helping through lessening children's reactivity.     

Collaborative Exhibitions and Visitor Reactions: The Case of Nitsitapiisinni: Our Way of Life

Collaborative exhibitions built by aboriginal communities and museums often seek to reposition aboriginal peoples as the authors and experts of their cultures, and to assert their active and continued presence in the contemporary world. This article explores the impact of collaborative exhibitions on museum visitors' experiences and their potential to reshape the public's perception of aboriginal peoples. Interviews conducted with visitors to Nitsitapiisinni: Our Way of Life, a permanent exhibition created by Blackfoot Elders and museum staff at the Glenbow Museum in Calgary, Alberta, Canada, demonstrate that museum visitors rarely recognized the extent of the collaboration, and thus rarely equated Nitsitapiisinni with concepts of self‐representation or self‐determination. However, other messages were successfully communicated to museum visitors, namely the impact of colonialism, the efforts to revitalize Blackfoot culture, and the importance of Blackfoot spirituality. This study provides some interesting insights about public perceptions that will help promote deeper reflection on the issues surrounding collaboratively developed exhibitions and the first‐person authorship of First Nations cultures.     

A review of educators' attitudes toward handicapped children and the concept of mainstreaming

Literature is reviewed related to the attitudes of educators toward handicapped children and the concept of mainstreaming these youngsters into regular class settings. Opinionnaire data suggest that regular class educators, particularly those with little formal training or experience in special education, do not favor mainstreaming. Moreover, these educators view handicapped children as generally less able to benefit from schooling. Research is also reviewed that documents the relationship between teachers' attitudes toward individual pupils and the differential instructional treatment of children. Finally, efforts to modify the attitudes and perceptions of educators toward handicapped children and mainstreaming are presented.     

Is syllable segmentation developmentally constrained by consonant sonority within syllable boundaries in silent reading? Evidence in French children

There is agreement that French typically reading children use syllable‐sized units to segment words. Although the statistical properties of the initial syllables or the clusters within syllable boundaries seem to be crucial for syllable segmentation, little is known about the role of consonant sonority in silent reading. In two experiments that used audio‐visual and visual pseudoword recognition tasks with 300 French typically developing children, we showed a progressive increase in the use of syllable segmentation from the first through fifth years of reading instruction. The children were influenced both by an optimal ‘sonorant coda–obstruent onset’ sonority profile and by the individual position‐dependent consonant sonority within syllable boundaries. Orthographic and phonological statistical properties did not clearly modulate the response patterns. We provide innovative data to help further understand the developmental course of the use of syllable segmentation as determined by sonority. We discuss our results in the light of linguistic principles.
