Adolescent physical activity levels: discrepancies with accelerometer data analysis

This study investigated the effects of epoch length and cut point selection on adolescent physical activity intensity quantification using vertical axis and vector magnitude (VM) measurement with the ActiGraph GT3X+ accelerometer. Four hundred and nine adolescents (211 males; 198 females) aged 12–16 years of age wore accelerometers during waking hours. The GT3X+ acceleration counts were reintegrated into 1, 5, 15, 30 and 60 s epoch lengths for both vertical axis and VM counts. One cut point was applied to vertical axis counts and three different cut points were applied to VM counts for each epoch length. Significant differences (P < 0.01) in mean total counts per day were observed between vertical axis and VM counts, and between epoch lengths for VM only. Differences in physical activity levels were observed between vertical and VM cut points, and between epoch lengths across all activity intensities. Our findings illustrate the magnitude of differences in physical activity outcomes that occur between axis measurement, cut points and epoch length. The magnitude of difference across epoch length must be considered in the interpretation of accelerometer data and seen as a confounding variable when comparing physical activity levels between studies.     

A new jump-landing protocol identifies differences in healthy,coper, and unstable ankles in collegiate athletes

Ankle sprains are the most common injury in sport. With stability being an important risk factor for ankle sprains, a jump-landing protocol that can elicit differences in time-to-stabilisation (TTS) is necessary. The objective of this study was to develop a jump-landing protocol that could identify differences in TTS among healthy, ‘coper’, and unstable ankles of high-level athletes. 61 Division I collegiate athletes (32 females, 29 males; age: 19.9 ± 1.2 years; height: 176.6 ± 9.5 cm; mass: 74.3 ± 10.8 kg) participated in a jump-landing protocol that utilised sporting movements with preparatory steps and a vertical propulsion of the body in two multi-directional jumps. Utilising the landing on a force plate, ground reaction forces were used to quantify TTS. TTS of the unstable group (1.58 ± 0.62s) was significantly longer than the healthy (1.19 ± 0.37s; p = 0.050) and ‘coper’ (1.13 ± 0.49s; p = 0.019) groups in the forward hops. In addition, TTS of the lateral hops in the unstable group (1.55 ± 0.63s) was also significantly longer than the healthy (1.14 ± 0.37s; p = 0.026) and ‘coper’ (1.15 ± 0.39s; p = 0.028) groups. This new jump-landing protocol was able to elicit differences in TTS in high-level athletes that were not found using previous protocols. This new jump-landing protocol could be an effective tool to identify injury risk for high-level athletes.     

Multicultural Inclusion of Lesbian and Gay Literature Themes in Elementary Classrooms

This article provides a rationale for and methods to assist elementary educators in creating spaces where the enhancement of awareness of lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ)-themed literature could be explored in elementary schools and classrooms. The authors assert that an approach to providing gender and sexuality diversity in the elementary grades is part of multicultural practice in elementary classrooms. Through document analysis, the authors discovered the existing theories, practices, and evidence available in the literature that would provide elementary educators support to use LGBTQ-themed children's literature in academic spaces. The authors then provide a set of guidelines for educators to modify their existing instructional practices in order to empower young learners with the critical literacy attributes necessary in order to gain access to knowledge, power, and opportunities.     

Teacher Contracts and Staff Development on Pupil‐Free‐Days

Sex bias in the curriculum is a relatively recent concern of the educational establishment. In 1975 the Sex Discrimination Act established the principle of equal access to educational facilities and equality of treatment for girls and boys. In the same year the HMI catalogued the sexually differentiated curriculum of girls and boys in Education Survey 21 and this surprisingly enlightened pamphlet thrust the issue onto the mainstream educational agenda. Up to that point sexual inequity in education had tended to be perceived as the prerogative of the teaching profession (overwhelmingly female but with few women in senior posts) and the particular promotion prospects of women teachers. The passing of the Sex Discrimination Act has done little to remedy the promotion prospects of women teachers, and in education generally the issue has moved beyond the realm of curricular access and into the less clearly charted territory of sexual differentiation: attention needs to be directed less to the examined curriculum patterns accessible to anyone willing to plough their way through the yearly statistics issued by the Department of Education and Science and focused more on the subtle processes through which girls' and boys' aspirations and expectations are shaped. Examination outcomes are convenient proof that ‘equal access’ has merely ensured that the educational experience of boys and girls continues to differ. This article, then, attempts to address some of the schooling processes as well as the curricular patterns.     

Gamers and gaming context: Relationships to critical thinking

Gaming is purported to hold promise for education, in part, because it is thought to develop 21st century skills such as critical thinking. To date, there has been a dearth of generalisable research investigating the relationship between gaming and critical thinking. Results of a survey of 121 adults found that gamers and non‐gamers do not differ significantly on critical thinking dispositions. However, gamers who play strategy games scored higher on actively open‐minded thinking than did other types of gamers. In addition, low compared with high involvement in the gaming community was associated with higher open‐minded thinking. Implications for educators and for further research are discussed.     

Rapid serial naming and reading ability: the role of lexical access

Rapid serial naming tasks are frequently used to explain variance in reading skill. However, the construct being measured by rapid naming is yet undetermined. The Phonological Processing theory suggests that rapid naming relates to reading because of similar demands of access to long-term stored phonological representations of visual stimuli. Some researchers have argued that isolated or discrete-trial naming is a more precise measure of lexical access than serial naming, thus it is likely that any shared variance between these two formats can be attributed to similar lexical access demands. The present study examined whether there remained any variance in reading ability that could be uniquely explained by the rapid naming task while controlling for isolated naming. Structural equation modeling was used to examine these relations within the context of the phonological processing model. Results indicated that serial naming uniquely predicted reading, and the relation was stronger with isolated naming controlled for, suggesting that isolated naming functioned as a suppressor variable in the relation of serial naming with reading.     

Removing Judgement: Discussing BDSM in Adult Sexuality Education

With increasing cultural attention to kink and BDSM (Bondage/Discipline, Dominance/Submission, and Sadism/Masochism), it is more important than ever for sexuality educators to teach these topics with respect and acceptance. Many depictions of BDSM in the media are deliberately shocking. With limited resources and research surrounding the topic, it can be difficult for educators to not fall into the same trap. This paper discusses the impact of the shock-culture surrounding BDSM and offers suggestions for combating it in the classroom via implementing a combination of affective and cognitive learning.     

Enhancing Socio-technical Governance: Targeting Inequality in Innovation Through Inclusivity Mainstreaming

Socio-technical governance has been of long-standing interest to science and technology studies and science policy studies. Recent calls for midstream modulation direct attention to a more complicated model of innovation, and a new place for social scientists to intervene in research, design and development. This paper develops and expands this earlier work to demonstrate how a suite of concepts from science and technology studies and innovation studies can be used as a heuristic tool to conduct real-time evaluation and reflection during the process of innovation – upstream, midstream, and downstream. The result of this new protocol is inclusivity mainstreaming: determining if and how marginalized peoples and perspectives are being maximally incorporated into the model of innovation, while highlighting common problems of inequality that need to be addressed.
