Abstract
Oranchuk, DJ, Ecsedy, EN, and Robinson, TL. Effects of a sport-specific upper-body resistance-band training program on overhead throwing velocity and glenohumeral joint range of motion. J Strength Cond Res 35(11): 3097–3103, 2021—Practitioners seek optimal, yet practical means to enhance performance while aiming to minimize injury risk. Resistance bands offer portability and safety and enable similar movements to competition. However, the effect of movement-specific resistance-band training on throwing performance and markers of injury risk has yet to be elucidated. Therefore, the purpose of this study was to compare the effects of a resistance training program using resistance bands with sport-specific (SS), or general-training (GT) exercises. Twenty-eight collegiate female softball players were randomly allocated to an SS (n = 15) or GT (n = 13) 8-week resistance-band program. Dependent variables included peak and mean throwing velocity, 1 repetition maximum (1RM) cable Chop-test, and glenohumeral internal and external rotation range of motion (ROM). No significant (p ≤ 0.338) differences were found between groups at baseline. Improvements in peak (p = 0.006, 4.9%, effect size [ES] = 0.61) and mean (p = 0.004, 3.1%, ES = 0.49) throwing velocity were seen after SS training, while the 1RM Chop-test increased in both SS (p < 0.001, 23.5%, ES = 1.06) and GT (p = 0.049, 26.1%, ES = 0.57) groups. However, no between-group differences (p ≥ 0.109, ES ≤ 0.17) were present in any variable. Neither the Chop-test nor shoulder internal or external ROM had more than moderate correlations with throwing velocity (r ≤ 0.30, p ≥ 0.119). Therefore, practitioners should not depend solely on SS resistance-band training when aiming to improve throwing velocity or measures of shoulder rotational health. However, resistance bands appear to be a practical alternative when traditional means of resistance training are not available. In addition, strength and conditioning coaches should not use the Chop-test or shoulder ROM to predict throwing performance.

Abstract
O'Grady, MW, Young, WB, Behm, DG, and Talpey, SW. Effect of intention to squat explosively on acute countermovement jump performance. J Strength Cond Res 35(12): 3348–3354, 2021—The purpose of this study was to investigate the influence of squatting with the intention of moving the bar as fast as possible during the ascent phase on potentiating countermovement jump (CMJ) performance. Fourteen recreationally resistance-trained men (age = 22.1 ± 1.7 years, height = 179.9 ± 4.2 cm, body mass = 83.8 ± 6.6 kg) with a predicted 1 repetition maximum half-squat of 201.0 ± 27.8 kg participated in this study. Subjects performed 3 CMJs before and then 4 and 8 minutes after a squat conditioning activity (CA). Conditions were randomized. For 1 condition, the CA involved subjects performing 4 repetitions of the half-squat with a 5RM load in a controlled manner (CON) at a self-selected normal squatting tempo. In the other condition, subjects used the same number of repetitions and load; however, they were instructed to move the bar up as fast as possible during the concentric phase of the half-squat (VMAX). Half-squat peak force (N), peak power (W), peak velocity (m·s−1), and rate of force development (RFD) were measured for each CA using a force platform and linear position transducer. At 4 and 8 minutes post-CA, CMJ height, relative peak power, peak velocity, and peak force were also measured. Despite there being significant increases in the half-squat peak power, peak velocity and maximum RFD in the VMAX condition, neither condition significantly improved any post-CMJ variable. Some small improvements in jump height were observed in certain individuals after the VMAX condition, suggesting that an explosive half-squat CA may potentiate CMJ performance in certain individuals.

Abstract
Devine, NF, Hegedus, EJ, Nguyen, A-D, Ford, KR, and Taylor, JB. External match load in women's collegiate lacrosse. J Strength Cond Res 36(2): 503–507, 2022—Quantifying external loads during athletic activities, particularly game-level competition, can provide objective data for the management of athlete performance, late-stage rehabilitation, and return-to-play decisions after lower extremity injury; yet, no studies have quantified these data in collegiate women's lacrosse athletes. The purpose of this study was to report external load values for collegiate women's lacrosse players and identify positional differences in activity demands during game competition. Load data were collected on 18 collegiate women's lacrosse players using a wearable global positioning system unit during a 19-game season. Descriptive statistics of distance, speed, and frequency (sprints, high-intensity sprints, high-intensity accelerations, high-intensity decelerations) measures were computed. Linear mixed models were used to identify differences between positions and phases of the season (α = 0.05). On average, players travelled 4,733 ± 2,294 m per game (range, 1,259–7,811 m), of which 656 ± 446 m (range 60–1,633 m) occurred at high-intensity speeds and reached a maximum speed of 24.1 ± 2.6 km·h−1 (range, 19.2–27.7 km·h−1). In each game, subjects averaged 124 ± 68 sprints, 6.1 ± 4.1 high-intensity sprints, 51 ± 34 high-intensity accelerations, and 38 ± 25 high-intensity decelerations. Positional differences were identified for total (p = 0.04) and relative (p = 0.01) distance travelled at high-intensity speeds, and frequency of sprints (p = 0.01) and high-intensity decelerations (p = 0.03). During game competition, collegiate women's lacrosse demands significant external load, much of which occurs at high intensities. These data provide sport- and position-specific values for reference during late-stage rehabilitation and return-to-play testing, allowing clinicians to quantitatively progress load tolerance throughout rehabilitation and guide safe return to play.

ABSTRACT
This article presents an overview of the rehabilitation and return to sport following a nonsurgical Achilles tendon (AT) rupture. A brief description of the recognition and diagnosis of the injury, selection of nonoperative treatment, outcome measures, importance of range of motion, purpose of functional rehabilitation, description of the rehabilitation phases, and return to play progressions are included. A well-designed early functional rehabilitation program is more important than the method of treatment in outcomes and functional performance with AT ruptures.

Abstract
A suction-controlled ring device has been developed to continuously measure the coefficient of lateral soil pressure in deformable unsaturated soil samples from the at-rest to the active condition under application of increasing vertical pressure and controlled matric suction. The device incorporates a thin aluminum specimen ring equipped with horizontal strain gages for recording the lateral soil strains. In addition, a sensor recording water volume changes is utilized to continuously monitor the degree of saturation of the soil sample during tests. The matric suction within the soil texture is controlled using the axis translation technique. In order to verify the performance of the ring device, twenty suction-controlled tests under application of five different constant matric suctions have been performed on two different unsaturated soil types, namely Firouzkouh Clay and Sand-Kaolin mixture, each with two different initial densities. During tests, the lateral soil pressure and corresponding lateral strains have been continuously recorded from the at-rest to the active state of the soil. Accordingly, the coefficients of the lateral soil pressure for the at-rest and the active states of the soil are calculated based on the experimental data and by considering the effective stress concept in unsaturated soils. Finally, the observed responses have been analyzed and the effects of initial density and matric suction on the ratio of lateral to vertical soil pressure have been discussed.

Published: February 2020

As dinâmicas da representação parlamentar no Brasil suscitam uma questão central: em que medida quem ocupa os cargos afeta os tipos de políticas aprovadas? Dado que as evidências empíricas não são conclusivas sobre tal questão, este artigo propôs-se analisar a efetividade da representação descritiva de gênero e de “raça” na Câmara dos Deputados e em Assembleias Legislativas de sete estados (legislatura 2015-2019), utilizando para isso um questionário de 65 itens que foi aplicado a uma amostra aleatória de 300 Membros do Parlamento. Um “índice de produção legislativa específica”, baseado na taxa de sucesso das proposições transformadas em leis, foi criado como proxy de representaçãosubstantiva. Índices significativamente maiores de produção legislativa específica foram encontrados entre as/os representantes descritiva/os (M = 1.95/0.27), o que sugere uma forte correlação entre as duas formas de representação. As variáveis “gênero” (Exp(B)=5,497) e “ideologia” (Exp(B)=14,149) mostraram-se especialmente robustas como preditoras de representação substantiva.

Published: February 2020

Elaboramos uma análise das inter-relações entre os discursos das políticas federais de cultura no Brasil com a renovação do neoliberalismo e com a teoria econômica das organizações. Construímos um levantamento histórico das recentes políticas públicas federais de cultura e identificamos três momentos: (1) a década de 1990 marcada pelo discurso do estado mínimo, relacionado às políticas de cultura direcionadas pelas leis de incentivo fiscal; (2) nos anos 2000, com políticas voltadas à diversidade e foco nas manifestações populares; e (3) a partir de 2010, percebemos políticas que reconfiguram o foco econômico da década de 1990, com as teorias do empreendedorismo e da regulação e o novo neoliberalismo, produzindo significados e significantes, como Indústria e Economia Criativa. Observamos que a Política Federal de Economia Criativa dissemina a generalização da forma empresa e, em consequência, do empreendedorismo, como solução paraproblemas sociais como geração de trabalho e renda, o que reconhecemos comoum experimento inserido na renovação do neoliberalismo.

Behavioral and Transcriptional Response to Selection for Olfactory Behavior inDrosophila
Authors: Brown Elizabeth B , Layne John E , Elchert Alexandra R , Rollmann Stephanie M 
Published: February 2020

AbstractThe detection, discrimination, and behavioral responses to chemical cues in the environment can have marked effects on organismal survival and reproduction, eliciting attractive or aversive behavior. To gain insight into mechanisms mediating this hedonic valence, we applied thirty generations of divergent artificial selection for Drosophila melanogaster olfactory behavior. We independently selected for positive and negative behavioral responses to two ecologically relevant chemical compounds: 2,3-butanedione and cyclohexanone. We also tested the correlated responses to selection by testing behavioral responses to other odorants and life history traits. Measurements of behavioral responses of the selected lines and unselected controls to additional odorants showed that the mechanisms underlying responses to these odorants are, in some cases, differentially affected by selection regime and generalization of the response to other odorants was only detected in the 2,3-butanedione selection lines. Food consumption and lifespan varied with selection regime and, at times, sex. An analysis of gene expression of both selection regimes identified multiple differentially expressed genes. New genes and genes previously identified in mediating olfactory behavior were identified. In particular, we found functional enrichment of several gene ontology terms, including cell-cell adhesion and sulfur compound metabolic process, the latter including genes belonging to the glutathione S-transferase family. These findings highlight a potential role for glutathione S-transferases in the evolution of hedonic valence to ecologically relevant volatile compounds and set the stage for a detailed investigation into mechanisms by which these genes mediate attraction and aversion.
Caenorhabditis elegans Gastrulation: A Model for Understanding How Cells Polarize, Change Shape, and Journey Toward the Center of an Embryo
Authors: Goldstein Bob , Nance Jeremy 
Published: February 2020

Abstract
Gastrulation is fundamental to the development of multicellular animals. Along with neurulation, gastrulation is one of the major processes of morphogenesis in which cells or whole tissues move from the surface of an embryo to its interior. Cell internalization mechanisms that have been discovered to date in Caenorhabditis elegans gastrulation bear some similarity to internalization mechanisms of other systems including Drosophila, Xenopus, and mouse, suggesting that ancient and conserved mechanisms internalize cells in diverse organisms. C. elegans gastrulation occurs at an early stage, beginning when the embryo is composed of just 26 cells, suggesting some promise for connecting the rich array of developmental mechanisms that establish polarity and pattern in embryos to the force-producing mechanisms that change cell shapes and move cells interiorly. Here, we review our current understanding of C. elegans gastrulation mechanisms. We address how cells determine which direction is the interior and polarize with respect to that direction, how cells change shape by apical constriction and internalize, and how the embryo specifies which cells will internalize and when. We summarize future prospects for using this system to discover some of the general principles by which animal cells change shape and internalize during development.
Physiology, Development, and Disease Modeling in the Drosophila Excretory System
Authors: Cohen Erez , Sawyer Jessica K , Peterson Nora G , Dow Julian A T , Fox Donald T 
Published: February 2020

Abstract
The insect excretory system contains two organ systems acting in concert: the Malpighian tubules and the hindgut perform essential roles in excretion and ionic and osmotic homeostasis. For over 350 years, these two organs have fascinated biologists as a model of organ structure and function. As part of a recent surge in interest, research on the Malpighian tubules and hindgut of Drosophila have uncovered important paradigms of organ physiology and development. Further, many human disease processes can be modeled in these organs. Here, focusing on discoveries in the past 10 years, we provide an overview of the anatomy and physiology of the Drosophila excretory system. We describe the major developmental events that build these organs during embryogenesis, remodel them during metamorphosis, and repair them following injury. Finally, we highlight the use of the Malpighian tubules and hindgut as accessible models of human disease biology. The Malpighian tubule is a particularly excellent model to study rapid fluid transport, neuroendocrine control of renal function, and modeling of numerous human renal conditions such as kidney stones, while the hindgut provides an outstanding model for processes such as the role of cell chirality in development, nonstem cell–based injury repair, cancer-promoting processes, and communication between the intestine and nervous system.
STEM Education: From Sputnik to Girl Scouts
Authors: Vaitekaitis Jogaila 
Published: February 2020

The inconsistency of defining STEM (Science, Technology, Engineering, and Math) education is being addressed in this article. Seeing STEM education as having implications ranging from migration to workforce policies, it is vital to clarify its (inter)disciplinary structure and curriculum orientation. Using a literature review and analysis of documents, STEM education is being tracked from a post-sputnik era to more recent informal and private endeavors, revealing a multiplication of the STEM acronym and the diversification of its curriculum orientation. The findings confirm that there is no consensus on the exact scientific fields assigned to STEM, and the list of disciplines involved ranges from broad (including Social sciences, Humanities or Arts) to narrow (dominated by Natural and Formal sciences). The article implies that historical context and reforms in natural science education partly explain this inconsistency, as the subjects and their interdisciplinary relations are closely linked to overall curriculum orientation, which could be seen as cyclical in nature, swinging from child centered to labor market or subject centered curriculum, inviting to discuss modern science education not as singular STEM, but as plural STEMs viable to multiple pedagogical approaches, integration patterns and aims.
