The effect of beetroot juice supplementation on repeat-sprint performance in hypoxia

This investigation assessed the effect of dietary nitrate (NO₃^?) supplementation, in the form of beetroot juice (BR), on repeat-sprint performance in normoxia and normobaric hypoxia. 12 male team-sport athletes (age 22.3 ± 2.6 y, VO_2peak 53.1 ± 8.7 mL.kg^?1.min^?1) completed three exercise trials involving a 10 min submaximal warm-up and 4 sets of cycling repeat-sprint efforts (RSE; 9 × 4 s) at sea level (CON), or at 3000 m simulated altitude following acute supplementation (140 mL) with BR (HYP_BR; 13 mmol NO₃^?) or NO₃^–depleted BR placebo (HYP_PLA). Peak (PPO) and mean (MPO) power output, plus work decrement were recorded during the RSE task, while oxygen consumption (VO₂) was measured during the warm-up. There were no significant differences observed between HYP_BR and HYP_PLA for PPO or MPO; however, work decrement was reduced in the first RSE set in HYP_BR compared with HYP_PLA. There was a moderate effect for VO₂ to be lower following BR at the end of the 10 min warm-up (ES = 0.50 ± 0.51). Dietary NO₃^? may not improve repeat-sprint performance in hypoxia but may reduce VO₂ during submaximal exercise. Therefore, BR supplementation may be more effective for performance improvement during predominantly aerobic exercise.     

School-psychological providers: A national survey of state departments of education

To identify professional groups that are providing psychological services in the schools, the present national survey of state departments of education was conducted. Fifty-nine percent of states currently mandate services of school psychologists by law, and a variety of allied professional groups were identified as also providing psychological services in the schools. Specific information about provider groups and service mandates is reported. Recommendations relevant to the provision of quality school-psychological services and utilization of multiple providers are given.     

Space modulators and the gat people: Ambiguity reduction and mass communications

There are many different ways of looking at mass communications’ basic role. Professor William L. Burke, who teaches broadcasting and film courses at Kansas State University, offers as his thesis that the basic task of communications in general is in reducing ambiguity, and that a labeled space modulator is far better than an unlabeled one in doing this!     

The Influence of Female Lead Characters in Political TV Shows: Links to Political Engagement

This study examined political television dramas with lead female characters, proposing a model that links viewing of these shows with political engagement. A survey revealed that regular viewers of Madam Secretary, The Good Wife, or Scandal reported feeling transported by these programs’ narratives and parasocial relationships with the main characters (i.e., women in positions of political leadership). These responses were also related to increases in political interest and self-efficacy, with interest predicting real-world political participation. The findings illustrate that these political dramas have prosocial implications, including the non-stereotypical representation of women as well as increased political engagement among viewers.     

Conceptualising Intergenerational Lived Experience: Integrating Art–Moving–Well-Being across Disciplines,Communities and Cultures

Art and movement are motivating forces in, through, and beyond education. As populations age, there is an increasing need to support physical and social well-being. Yet, since the onset of the COVID-19 pandemic, there has been a reported exponential increase in feelings of loneliness across generations. Complex challenges require trans-disciplinary solutions, and this paper represents a joint effort within and across disciplines, communities and cultures to find ways to ameliorate this silent epidemic. In this paper, we propose a cross-disciplinary conceptual framework where Aboriginal Artists and Knowledge Holders, Teacher Educators, and Physical and Occupational Therapists come together to explore theoretical and pedagogical insights that encompass intergenerational art–moving–well-being practices, reducing feelings of loneliness and improving social connections across generations. There are two main aims of this paper; first, to better understand current studies that report on integrating art–moving–well-being practices, and the effect this has on health and well-being of intergenerational participants (under 10-year-olds, 20+ year olds and 50+ year olds). Second, based on community needs, the long-term aim is to propose a flexible art–moving–well-being conceptual model that is scalable, sustainable and based on social and relational support systems. We propose a model that is flexible and adaptable within and across our local community and beyond. We argue that feelings of loneliness are unique to each individual, and there is a need to connect specific intergenerational programmes with art–moving–well-being practices that readily engage and integrate varied communities and cultures in sustainable ways and thus, contribute to thriving communities.     

Promoting Inquiry-Based Teaching in Laboratory Courses: Are We Meeting the Grade?

Over the past decade, repeated calls have been made to incorporate more active teaching and learning in undergraduate biology courses. The emphasis on inquiry-based teaching is especially important in laboratory courses, as these are the courses in which students are applying the process of science. To determine the current state of research on inquiry-based teaching in undergraduate biology laboratory courses, we reviewed the recent published literature on inquiry-based exercises. The majority of studies in our data set were in the subdisciplines of biochemistry, cell biology, developmental biology, genetics, and molecular biology. In addition, most exercises were guided inquiry, rather than open ended or research based. Almost 75% of the studies included assessment data, with two-thirds of these studies including multiple types of assessment data. However, few exercises were assessed in multiple courses or at multiple institutions. Furthermore, assessments were rarely based on published instruments. Although the results of the studies in our data set show a positive effect of inquiry-based teaching in biology laboratory courses on student learning gains, research that uses the same instrument across a range of courses and institutions is needed to determine whether these results can be generalized.
