Les réseaux sociaux numériques offrent-ils une alternative 2.0 aux pratiques traditionnelles de mobilisation collective dans le monde du travail ?
Authors: Sauvajol-Rialland Caroline 
Published: February 2020

En France en 2011, trois entreprises du secteur de la grande distribution et du secteur du prêt-à-porter (Monoprix, Cora et Kookaï) ont fait l'objet de mobilisations « éclair » menées sur les réseaux sociaux à la suite desquelles deux d'entre elles ont renoncé aux décisions managériales qu'elles avaient prises (licenciements). Au-delà des différences de formes (déjà étudiées et liées aux technologies utilisées), existe-t-il une véritable différence de nature entre les formes de mobilisation sur les réseaux sociaux numériques et les formes traditionnelles de mobilisation collective dans le monde du travail ? L'objectif est de montrer l'apparition d'une nouvelle forme de mobilisation collective dans le monde du travail, spécifique dans sa nature et dans ses modalités. Compte tenu du caractère extrêmement récent des événements décrits, nous avons choisi une démarche descriptive et exploratoire, ainsi qu'une analyse de presse et une revue de la littérature existante. Plusieurs spécificités de nature se dégagent à l'analyse : la nature de la présence, la nature du lien social, et enfin la nature de l'engagement. Notre conclusion principale est l'apparition dans le monde du travail d'une nouvelle forme de mobilisation collective spécifique dans sa nature. Elle constitue une nouvelle opportunité de communication qui, sans se substituer aux typologies de mobilisation traditionnelles dans le monde du travail, vient se rajouter à elles. Elle apparaît comme fortement liée à l'avènement de la génération née entre 1985 et 1995 que le professeur et chercheur américain Mark Prensky a baptisé, dans un essai désormais célèbre,« Digital Native » (Prensky, 2001), les véritables « autochtones » du web.
Public Engagement with, and Trust in, Online News Media in French-Speaking Belgium
Authors: Rosas Omar 
Published: February 2020

This paper analyzes the French-speaking Belgian public’s reception of, and trust in, online news media. Based on a qualitative research carried out in 2009-2010, it will be showed that online newsreaders hold divided conceptions of media credibility and trust, some of which fall out of the theoretical/methodological canon of current media credibility research. Furthermore, respondents appeared to draw upon four heuristics to decide whether or not they place their trust in online news: the transparency heuristic, the accountability heuristic, the reputation heuristic, and the recommendation heuristic. The relevance of these heuristics to trust is clear insofar as they affect both newsreaders’ attributions of trustworthiness to online journalists and news media, and their willingness to engage in trusting relationships with them. At the end of the paper, some conclusions and implications for future research on trust in online news are discussed.
Communication et dynamiques d’hybridation dans les organisations de type laboratoire vivant : un regard constitutif sur le démarrage d’un living lab au service des aînés
Authors: Baillargeon Dany , Bruneau Hélène 
Published: February 2020

Ancrée dans le paradigme de l’innovation ouverte, la méthodologie laboratoire vivant (living lab) met en relation chercheurs, représentants des secteurs public et privé et citoyens afin de créer des solutions innovantes à des problématiques complexes. À travers un partage mutuel de connaissances et d’expériences autour d’un but commun, ce mode d’organisation hybride suppose également de maintenir les intérêts de chaque acteur, ce qui vient avec son lot de tensions. À partir d’une analyse des figures (Cooren, 2013) animées dans des textes et des conversations entourant le démarrage d’un laboratoire vivant axé sur les enjeux du vieillissement, nous exposons différentes tensions émanant du processus d’hybridation, mais également le favorisant. Quatre enjeux sont particulièrement porteurs des tensions : le statut du laboratoire, son fonctionnement, la représentation des parties prenantes et la terminologie en usage. D’un point de vue constitutif, nous démontrons que les tensions liées à l’appartenance participent du processus d’hybridation, ce dernier étant fait de dynamiques de détachements/rattachements.
L'art de dire et de faire le goût : les médiations culturelles dans un manga culinaire
Authors: Deramond Julie , Lambert Emmanuelle 
Published: February 2020

A travers l'étude monographique d'un manga spécialisé sur le vin et la cuisine (Les Gouttes de Dieu, de Tadashi Agi et Shu Okimoto), cet article analyse les questions de mise en correspondance des sens, de croisement des arts et d'interculturalité pour montrer comment s'élaborent des formes de médiations et de médiatisation des goûts culinaires, esthétiques et culturels. Le manga, considéré comme médiaculture, se fait ainsi non seulement discours sur le vin mais également passeur de formes, d'objets et de valeurs culturels, devenant prescripteur. Entre discours expert et profane, terminologies professionnelle et autodidaxique, il s'apparente alors à une forme hybride de critique œnologique. Cette bande dessinée japonaise nous invite donc à penser les processus et discours communicationnels liés à la construction du goût, œnologique et esthétique.
North-South Distribution and Asymmetry of GOES SXR Flares during Solar Cycle 24
Authors: Joshi Anita , Chandra Ramesh 
Published: February 2020

Abstract
Here we present the results of the study of the north-south (N-S) distribution and asymmetry of GOES soft X-ray (SXR) flares during solar cycle 24. The period of study includes ascending, maximum and descending phases of the cycle. During the cycle double-peaked (2011, 2014) solar maximum has occurred. The cycle peak in the year 2011 is due to B-class flares excess activity in the northern hemisphere (NH) whereas C and M class flares excess activity in the southern hemisphere (SH) supported the second peak of the cycle in 2014. The data analysis shows that the SXR flares are more pronounced in 11 to 20 degree latitudes for each hemisphere. Cumulative values of SXR flare count show northern excess during the ascending phase of the cycle. However, in the descending phase of the cycle, southern excess occurred. In the cycle a significant SH dominated asymmetry exists. Near the maximum of the cycle, the asymmetry enhances pronouncedly and reverses in sign.
Highly porous, fast responding acrylamide hydrogels through emulsion polymerization using coconut oil
Authors: Dharmasiri Mihisirini Bhagya , Kuruwita Mudiyanselage Thilini 
Published: February 2020

Abstract
Conventional acrylamide hydrogel exhibits a slow swelling rate which limits its potential for novel applications. It is a formidable challenge to increase the rate of swelling and if addressed successfully, this paves new paths for significant advanced applications. Fast responding polyacrylamide hydrogels with microporous structures and an interconnected network of capillary channels have been successfully synthesized by free radical emulsion-templated polymerization (a 2.5 m acrylamide monomer solution was crosslinked with 1% N,N-methylenebisacrylamide using 5% potassium persulfate as the initiator). Virgin coconut oil (70% v/v) was used as the pore forming agent, which was dispersed in the aqueous monomer solution by using 5% non-ionic surfactant (Tween 80®). Developed porous acrylamide hydrogel displayed approximately 600 wt% water absorptivity compared to the dry weight of the sample in 15 s at 30°C. Swelling ratio and scanning electron microscopy studies uncovered the characteristic microporous structure of the hydrogel. Pores of the hydrogel are interconnected to form capillary channels and thus they are responsible for the higher swelling rate of the hydrogel.
Elder Law and Its Justifications: A Hybrid Vision Inspired by Family Law Jurisprudence
Authors: Hacker Daphna 
Published: February 2020

Abstract
This Article calls for a departure from the ‘positivist–professional’ definition of Elder Law. It offers a new definition that demands answers regarding the justifications for this legal area and the normative base that should guide its content. The paper draws on findings from a qualitative study with grown children who have an elderly parent in need. These findings point toward a) a preliminary theoretical framework that justifies a special area of Elder Law, embracing and transcending that of anti-ageist law, and b) the relevance of Family Law jurisprudence as a normative inspiration for this legal area.
Intergenerational Support of Older Adults by the ‘Mature’ Sandwich Generation: The Relevance of National Policy Regimes
Authors: Silverstein Merril , Tur-Sinai Aviad , Lewin-Epstein Noah 
Published: February 2020

Abstract
In this article we examine the association between national welfare regime and the propensity of middle–aged and older individuals with adult children of their own to provide social support to aged parents. Using data from mature adults (50+) in 26 European countries, we examine whether older and younger generations compete for the time resources of the middle “sandwiched” generation, and whether national policy context shapes this competition. Contrary to expectations, we found that sandwich generation members were less likely to provide support to their parents in Conservative–Mediterranean and East European regimes, but more likely to do so in universalistic Social–Democratic regimes. This evidence supports the hypothesis that well–developed welfare states “crowd–in” family support to older individuals. Middle generation members who provided social support to their adult children tended to provide to their older parents as well. This was particularly true in the two regimes where resources and public benefits tend to be more generous and may be interpreted as state benefits that reduce intergenerational competition. Findings are discussed in terms of the capacity of state policies to shape the allocation of family resources to older adults where extended family lineages have become the norm.

Abstract
Worcester, KS, Baker, PA, and Bollinger, LM. Effects of inertial load on sagittal plane kinematics of the lower extremity during flywheel-based squats. J Strength Cond Res 36(1): 63–69, 2022—Increasing load increases flexion of lower extremity joints during weighted squats; however, the effects of inertial load on lower extremity kinematics during flywheel-based resistance training (FRT) squats remain unclear. The purpose of this study was to evaluate sagittal plane kinematics of lower extremity joints during FRT squats at various inertial loads. Nine recreationally resistance-trained subjects (3M, 6F) completed a bout of FRT squats with inertial loads of 0.050, 0.075, and 0.100 kg·m2. Two-dimensional sagittal plane kinematics were monitored with retroreflective markers at a rate of 60 Hz. Joint angles and angular velocities of the knee, trunk + hip, trunk inclination, and ankle were quantified throughout concentric and eccentric actions. Effects of inertial load were determined by repeated-measures analysis of variance with α = 0.05. Average power and average vertical velocity decreased with increasing inertial load, whereas average force increased. Minimal and maximal sagittal plane joint angles of the knee, trunk + hip, trunk inclination, and ankle were not significantly different among inertial loads. However, peak joint angular velocities of the knee and trunk + hip tended to decrease with increasing inertial load. Conversely trunk inclination and ankle dorsiflexion velocities were not significantly different among inertial loads. Increasing inertial load from 0.050 to 0.100 kg·m2 significantly reduces average power during FRT squats primarily by decreasing movement velocity, which seems to be specific to the knee and hip joints. It is possible that lower concentric energy input at high inertial loads prevents increased joint flexion during FRT squats.

Abstract
Köklü, Y, Köklü, Ö, Işıkdemir, E, and Alemdaroğlu, U. Effect of varying recovery duration on postactivation potentiation of explosive jump and short sprint in elite young soccer players. J Strength Cond Res 36(2): 534–539, 2022—The purpose of this study was to investigate the effects of postactivation potentiation (PAP) on vertical jump and sprint performances with different recovery durations. Twelve elite young soccer players (average age: 17.0 ± 0.6 years; body mass: 67.0 ± 5.4 kg; height: 175.0 ± 3.5 cm) voluntarily performed countermovement jump (CMJ) and 30-m sprints (with 10-m split times) under unloaded and 4 different recovery duration conditions (R1: 1 minute, R2: 2 minutes, R3: 3 minutes, and R4: 4 minutes) after a set of 3 repetitions of half-squat exercises at 90% of 1-repetition maximum. Electromyographic assessments of both limbs' vastus lateralis (VL) and semitendinosus (ST) muscle activity were also made during the tests. Vertical jump height, sprint time, and VL and ST muscle activity root mean square (RMS) values were analyzed. The results show that players demonstrated significantly better CMJ, 10-, and 30-m sprint performances in the R4 condition compared with the unloaded condition (p < 0.05). The players also showed significantly higher RMS values for VL and ST muscle activity in the CMJ and 30-m test performances for both legs in the R4 condition compared with the unloaded, R1, R2, and R3 conditions (p < 0.05). According to these results, if sports scientists and coaches desire to increase the PAP effect after heavy resistance training, 4 minutes of recovery time instead of 1, 2, or 3 minutes for CMJ, 10-, and 30-m sprint performances is recommended.

Abstract
Scantlebury, S, Till, K, Sawczuk, T, Dalton-Barron, N, Phibbs, P, and Jones, B. The frequency and intensity of representative and nonrepresentative late adolescent team-sport athletes' training schedules. J Strength Cond Res 35(12): 3400–3406, 2021—This study aimed to identify and compare the training frequency and intensity (via session rating of perceived exertion load [sRPE load]) of representative and nonrepresentative late adolescent athletes. Thirty-six team sport athletes completed a web-based questionnaire daily over an 8-month period, reporting their training/match activities from the previous day. Athletes were categorized as representative (academy/county/international) or nonrepresentative (club/school) depending on the highest level of their sport they participated. Mean weekly frequencies and sRPE load of different training/match activities were quantified for each athlete across 5 school terms. Mann-Whitney U tests established the significance of differences and effect sizes between playing standards for mean weekly frequencies and mean sRPE load. Within-athlete weekly sRPE loads were highly variable for both playing standards; however, representative level athletes participated in significantly more activity outside of school compared with nonrepresentative athletes during November–December (effect size; 0.43—club technical training; 0.36—club matches), January–February (effect size; 0.78—club technical training; 0.75—club matches), and February–March (effect size; 0.63—club technical training; 0.44—club matches). Therefore, club and school coaches must ensure that all elements of representative athletes training schedules are coordinated and flexible to promote positive adaptions to training such as skill and physical development and prevent maladaptive responses such as overuse injury and nonfunctional overreaching. A cooperative and malleable training schedule between club/school coaches and the athlete will allow the athlete to perform on multiple fronts while also being able to meet the demands of additional stressors such as schoolwork.

Abstract
Orr, RM, Robinson, J, Hasanki, K, Talaber, KA, Schram, B, and Roberts, A. The relationship between strength measures and task performance in specialist tactical police. J Strength Cond Res 36(3): 757–762, 2022—Specialist tactical police officers (STPOs) carry heavier on-body loads than generalist police officers. Improvements in strength may mitigate the impacts of these heavier loads. The aim of this investigation was to determine the correlations between absolute and relative strength measures and occupational task performance in STPOs. Retrospective data were provided for 47 male specialist police officers from an elite Australian police unit. Data included body mass (mean = 89.0 ± 8.58 kg), strength measures (1 repetition maximum measures for a bench press, squat, deadlift, and pull-up), and task performance measures (85-kg victim drag wearing 15 kg of operational load and 5-km pack march wearing 40 kg of operational load). Pearson's correlations were conducted to determine relationships between measures and were plotted on a linear regressions model. Significant, moderate to strong correlations were found between all strength measures and victim drag performance and significant negative moderate correlations between relative bench press, absolute and relative squat, and absolute and relative pull-up and pack march times. The absolute deadlift had the strongest correlation to the victim drag (r = 0.747, p < 0.01) while the relative pull-up showed the strongest correlation with pack march performance (r = −0.466, p < 0.01). The requirement to lift a portion of the dummy off the ground during the victim drag may explain the increased importance of absolute strength while the requirement to transport load affixed to the body may explain the importance of relative strength requirements. Improvements in absolute and relative upper- and lower-body strength may improve task performance in this population.

Abstract
Medeiros, LHL, Sandbakk, SB, Bertazone, TMA, and Bueno Júnior, CR. Comparison of periodization models of concurrent training in recreationally active postmenopausal women. J Strength Cond Res 36(4): 977–983, 2022—Although concurrent training is the most effective way to improve both neuromuscular and cardiorespiratory functions in older populations, there are no studies in the literature comparing different periodization models on cardiorespiratory and muscle strength adaptations. Thus, the main objective of this study was to investigate the effects of different periodization models of concurrent aerobic and strength training using equalized training volume programs on muscle strength and cardiorespiratory fitness in recreationally active postmenopausal women. After 3 weeks of adaptation, 58 women aged 50–75 years were randomly assigned to (a) nonperiodization (NP), (b) daily nonlinear periodization (NLP), or (c) flexible daily NLP (FNLP). At baseline and after 12 weeks, aerobic fitness (peak oxygen uptake [V̇o
2peak] and the 6-minute walk test) and maximal muscle strength (1 repetition maximum of bench press and leg press) were measured. It was shown that maximal strength increased in the bench press (effect size [ES] 1.18 in NLP and 1.22 in FNLP) and leg press (ES 0.92 in NLP and 0.89 in FNLP) in the periodized groups—in the NP group, these values were 0.49 and 0.46, respectively. In the 6-minute walk test, aerobic fitness statistically improved in all groups—with an ES of 1.02 in the NP, 1.33 in the NLP, and 0.54 in the FNLP. This study showed that only periodization models (NLP and FNLP) induced a moderate ES in maximal strength, and all groups (NP, NLP, and FNLP) demonstrated improved aerobic fitness evaluated by V̇o
2peak and the 6-minute walk test in recreationally active postmenopausal women.

Published: February 2020

One of specific features of rocket engineering – is the high rate of sophistication and renewal of structures due to constantly growing operational and technical specifications imposed to them. Every generation of rocket and space products features a new complex of design and processing parameters and new materials possessing higher properties. It is impossible to resolve the entire scope of design and processing tasks in course of development, creation and operation of spacecraft without extend development and infusion of new materials which possess a number of required characteristics imposed to state-of-the-art technology products. The most widespread and sophisticated structures of modern technology – are solid-propellant rocket motors (SPRM) made of polymer composite materials. One of the major tasks associated with their creation is development of the internal thermal protection coating of solid-propellant rocket motor casing. State enterprise Yuzhnoye Design Office named after M.K. Yangel is currently carrying out works on creation of solid-propellant rocket motors. Development of their internal thermal protection coatings using mainly domestically produced materials with specified requirements is a scientific and technological task of high importance which confirms the relevance of dissertational research.The article is devoted to the analysis of components and ingredients for rubber compounds, which provide the properties and basic functions of the thermal protective covering of solid propellant rocket engine. The article shows the main results of the work related to the development of prescribed composition and technology of manufacturing of elastomeric material which used in the manufacture of internal heat-resistant coating of solid-propellant rocket engines made of polymer composite materials.
