Leadership, Mental Toughness, and Attachment Relationship in the World Beach Volleyball Context

For a long time, competitive sport has focused only on aspects related to performance. However, studies in social psychology have indicated the importance of focusing on the human development of athletes, which can occur through training environments that promote psychological well-being. Thus, this study aimed to analyze the impact of the coach-athlete attachment style, mediated by the coach’s leadership style, on the mental toughness of athletes in the world beach volleyball context. Elite beach volleyball athletes (n = 65), participants of the World Tour 2018, were part of the study. The Coach-Athlete Attachment Scale (CAAS), Mental Toughness Index (MTI) and Leadership Scale for Sport (LSS) were used as instruments. For data analyses we used polychoric correlation and a bias-corrected factor score path analysis. Path analysis showed that perceived secure attachment was positively associated with athletes’ mental toughness (0.24; 0.31; 0.25), but leadership styles did not mediate this relationship. For athletes with anxious attachment profiles, the perception of autocratic leadership style was associated with athletes’ mental toughness (1.01; p = 0.03), when their interaction style is focused on coaching-instruction. It concludes that the secure attachment relationship can bring increases in levels of athletic mental toughness, whereas for athletes with insecure attachment, the autocratic style was shown to be associated with the highest levels of mental toughness.
ONLINE COMPONENT CHALLENGES OF A BLENDED LEARNING EXPERIENCE: A COMPREHENSIVE APPROACH

This study aims to investigate: (1) the construct validity of the “Blended Learners’ Online Component Challenges” BLOCC scale. (2) the internal reliability of the scale, and (3) the differences between blended learners’ online component challenges according to different socio-demographic variables for Sport Science students. The sample of the study consisted of 263 students enrolled in blended learning classes at the School of Sport Sciences/ University of Jordan. The BLOCC scale was used to collect the required data. The scale measures the four different online component challenges; (1) Self-Management Challenges (SMC), (2) Technology Competency and Literacy Challenges (TCLC), (3) Student Isolation Challenges (SIC), and (4) Technological Sufficiency and Complexity Challenges (TSCC). BLOCC scale proved to be valid and reliable (four items were omitted); The overall fit statistics for the hypothesized four factor model ( χ 2 (df = 2.69) = 603.47, p < 0.001, (RMSEA) = . 08 indicated a moderate and acceptable fit to the data representing the latent factor structure. Discriminant validity ranged between . 53 and . 70. , Item-to-total correlation (.55 and .72), Cronbach Alpha (.72 and .86), and composite reliability (.74 -.95). Results of the study revealed that male students, students who have no internet accessibility, and those who have no previous experience in blended learning classes, all encountered significant higher levels of all BLOCC subscales. Older students (26-30 years old), and those with the lowest total income/ month (< 500 JD) encountered significant levels of TLCC and TSCC. Students with lower literacy in computer skills level encountered significant differences in SMC, TLCC and TSCC. We encourage future studies to propose and implement curative approaches to face such online component challenges.
“Consent Is Sexy”: exploring the portrayal of prosocial sexuality messages in youth-oriented series

ABSTRACT Content analyses on sexual messages in youth-oriented series have traditionally focused on the distribution of negative or antisocial sexual messages. As such, the potential of youth-oriented series to promote prosocial sexual messages (PSM) has been neglected. Grounded in the 3AM model, this content analysis fills this gap in the literature by examining the occurrence of PSM in youth-oriented series (e.g. Elite) on Netflix. A total of 126 characters (52% male, 48% female) and 3,151 scenes in 65 episodes were coded. The results indicate that PSM were promoted 4 times per episode (i.e. average length was 36 minutes) and were distributed by more than half of the characters. PSM also significantly co-occurred with antisocial sexual messages (ASM) in scenes, suggesting that sexual messages may operate as a “mixed” socialization agent for adolescents’ sexuality development. Further, characters in comedies and non-heterosexual characters more often distributed PSM than respectively characters in dramas and heterosexual characters. The promotion of PSM did not vary by characters’ gender. Implications of these findings in terms of audience effects and suggestions for future research are further discussed. IMPACT SUMMARY Prior State of Knowledge: While negative sexual messages in youth-oriented television series have been studied extensively, little is known about these television series’ potential to promote positive sexual messages. Novel Contributions: This content analysis addresses this gap in the literature. Positive sexual messages are frequently promoted in youth-oriented television series and co-occur with negative sexual messages. Also, they challenge the heterosexual script. Practical Implications: For parents and practitioners who view television as a tool for learning about sexuality, these results suggest that negative and positive sexual messages in television series co-occur. Providing explanations of these messages may be relevant for young viewers.
Experimental and Numerical Modeling of Overhanging Riverbank Stability

Overhanging riverbank stability is a key feature of bank retreat. Although different mechanisms of bank collapse have been studied by many researchers, prediction of cantilever failure patterns and understanding of three‐dimensional failure surfaces continue to puzzle scientists. To address this problem, we conducted laboratory experiments and numerical simulations to investigate the stability of overhanging riverbank. In the laboratory experiments, we analyzed the characteristics of failure surface using a three‐dimensional laser scanner. Results show that with decreased ratio between bank height and near‐bank water depth, there is a transition from a ‘tensile failures followed by toppling failure’ pattern to a ‘shear failure’ pattern. Flow infiltration in our experiments leads to a sharp decrease in soil shear strength and consequently the occurrence of shear failure. For toppling failure, the observed upper retreat distance is much greater than the lower undermining depth, thus challenging the widely adopted assumption of a constant failure surface along the endpoint of the cantilever. Also, we found that failure surface distance can be characterized by twice the width of the overhanging block. As for the failure surface angle, a negative linear correlation is proposed with respect to bank retreat distance, implying a distinct distribution of bank stability along the arched‐shape bank line induced by bank collapse events. Overall, our study deepens understanding of overhanging stability, providing a new perspective on bank retreat process, critical for the morphodynamics of rivers and estuaries.
Spherical, rolling magnet generators for passive energy harvesting from human motion

In this work, non-resonant, vibrational energy harvester architectures intended for human-motion energy scavenging are researched. The basic design employs a spherical, unidirectionally magnetized permanent magnet (NdFeB) ball that is allowed to move arbitrarily in a spherical cavity wrapped with copper coil windings. As the ball rotates and translates within the cage, the time-varying magnetic flux induces a voltage in the coil according to Faraday's Law. Devices ranging from 1.5 cm3 to 4 cm3 in size were tested under human activity scenarios—held in the user's hand or placed in the user's pocket while walking (4 km h−1) and running (14.5 km h−1). These harvesters have demonstrated rms voltages ranging from ∼80 mV to 700 mV and time-averaged power densities up to 0.5 mW cm−3.
Early Detection of Prolonged Decreases in Maximal Voluntary Contraction Force after Eccentric Exercise of the Knee Extensors

ABSTRACT Purpose We examined whether the magnitude of muscle damage indicated by changes in maximal voluntary isometric contraction (MVIC) strength 1 to 3 d after unaccustomed eccentric exercise (ECC) was correlated with changes in central and peripheral neuromuscular parameters immediately post-ECC. Methods Twenty participants (19–36 yr) performed six sets of eight eccentric contractions of the knee extensors. Rate of force development (RFD) during knee extensor MVIC, twitch force, rate of force development (RFDRT) and rate of relaxation (RRRT) of the resting twitch, maximal M-wave (MMAX), voluntary activation, silent period duration, motor-evoked potentials (MEP) and short-interval intracortical inhibition were assessed before, immediately after, and 1 to 3 d post-ECC. Relationships between changes in these variables immediately post-ECC and changes in MVIC strength at 1 to 3 d post-ECC were examined by Pearson product–moment (r) or Spearman correlations. Results Maximal voluntary isometric contraction strength decreased (−22.2% ± 18.4%) immediately postexercise, and remained below baseline at 1 (−16.3% ± 15.2%), 2 (−14.7% ± 13.2%) and 3 d post-ECC (−8.6% ± 15.7%). Immediately post-ECC, RFD (0–30-ms: −38.3% ± 31.4%), twitch force (−45.9% ± 22.4%), RFDRT (−32.5% ± 40.7%), RRRT (−38.0% ± 39.7%), voluntary activation (−21.4% ± 16.5%) and MEP/MMAX at rest (−42.5% ± 23.3%) also decreased, whereas the silent period duration at 10%-MVIC increased by 26.0% ± 12.2% (P < 0.05). Decreases in RFD at 0 to 30 ms, 0 to 50 ms, and 0 to 100 ms immediately post-ECC were correlated (P < 0.05) with changes in MVIC strength at 1 d (r = 0.56–0.60) and 2 d post-ECC (r = 0.53–0.63). Changes in MEP/MMAX at 10%-MVIC immediately post-ECC were correlated with changes in MVIC strength at 1 d (r = −0.53) and 2 d (r = −0.54) post-ECC (P < 0.05). Conclusions The magnitude of decrease in MVIC strength at 1 to 3 d after ECC was associated with the magnitude of changes in RFD and MEP/MMAX immediately post-ECC. However, based on individual data, these markers were not sensitive for the practical detection of muscle damage.
PROFITABILITY AND THE FIRM'S VALUE

The cause of this research is to investigate and prove the impact of ROA, ROE, NPM, and GPM on firm’s value (Tobin's Q) either partially or simultaneously and decide which profitability ratio is more dominant in explaining Tobin's Q variance. The analysis was carried out on companies listed in the Jakarta Islamic Index (JII) for 2015-2020. The sample selected was issuers consistently registered with JII during the 2015-2020 period, and 11 issuers were selected. The results of the analysis show ROA and NPM partially sizeable good-sized effect on Tobin's Q, whilst ROE and GPM do not have any effect. ROA is positively correlated, and NPM is negatively correlated. However, all independent variables simultaneously have a significant impact on Tobin's Q. The R-square value of is 0.953648 shows that 95.37% of Tobin's Q variance can be explained by changes in ROA, ROE, GPM, and NPM, while other factors outside the model cause the remaining 4.43%. Of the four variables tested, ROA is the more dominant variable affecting Tobin's Q and can be used as the best proxy for corporate profitability.
The journalist’s ‘toolbox’ of competencies in the Digital-Global Age: Reflections on the global state of research

The different crises that journalism continues to face worldwide make it imperative to talk about the journalist’s ‘toolbox’, a set of competencies that journalists must have in this so-called age of disruption. This article maps the global state of research on journalistic competence, offers ways of conceptualising journalistic competencies and provides the necessary context by which the development of the competency construct can be understood. What are the approaches in studying journalistic competence and what perspectives are dominant, clashing, or need to be challenged? The state of research shows an imbalance in perspectives: Studies on journalistic competencies are concentrated in US, Europe, and the Nordic states. The environments beyond the Western context or the ‘Global North’, so to speak, continue to be underrepresented, despite a strong research and journalism tradition unique to some of the Global South regions. Secondly, the industry perspective continues to dominate the discourse, although it has been described as hostile to innovation and critical reflection. The article ends with a call not just to further define and theorise journalistic competencies, but also to de-westernise the discourse.
Design Data for Radial-Waveguide Circulators Using Partial-Height Ferrite Resonators

This paper derives the eigennetworks of radial-waveguide circulators using partial-height ferrite resonators with n=2 Chebyshev characteristics. To obtain a Chebyshev response with such junctions it is necessary to establish the proper phase angles and admittance levels of the three eigennetworks of the device. This paper derives the phase angles for the eigennetworks but relies on experiments to establish the admittance levels. The configurations dealt with include the standard circulators using either half-wave-long ferrite resonators open circuited (OC) at both ends or coupled quarter-wave-long ferrite resonators OC at one end and short circuited (SQ) at the other. It also includes the design of a new single quarter-wave-long version, which is likely to replace the two more conventional arrangements in common usage. It is observed that the eigennetworks of any one of the geometries is sufficient to characterize the other two.
A Numerical Study of the Stiffness and Strength of Cross-Laminated Timber Wall-to-Floor Connections under Compression Perpendicular to the Grain

The use of cross-laminated timber (CLT) in multi-story buildings is increasing due to the potential of wood to reduce green house gas emissions and the high load-bearing capacity of CLT. Compression perpendicular to the grain (CPG) in CLT is an important design aspect, especially in multi-storied platform-type CLT buildings, where CPG stress develops in CLT floors due to loads from the roof or from upper floors. Here, CPG of CLT wall-to-floor connections are studied by means of finite element modeling with elasto-plastic material behavior based on a previously validated Quadratic multi-surface (QMS) failure criterion. Model predictions were first compared with experiments on CLT connections, before the model was used in a parameter study, to investigate the influence of wall and floor thicknesses, the annual ring pattern of the boards and the number of layers in the CLT elements. The finite element model agreed well with experimental findings. Connection stiffness was overestimated, while the strength was only slightly underestimated. The parameter study revealed that the wall thickness effect on the stiffness and strength of the connection was strongest for the practically most relevant wall thicknesses between 80 and about 160 mm. It also showed that an increasing floor thickness leads to higher stiffness and strength, due to the load dispersion effect. The increase was found to be stronger for smaller wall thicknesses. The influence of the annual ring orientation, or the pith location, was assessed as well and showed that boards cut closer to the pith yielded lower stiffness and strength. The findings of the parameter study were fitted with regression equations. Finally, a dimensionless ratio of the wall-to-floor thickness was used for deriving regression equations for stiffness and strength, as well as for load and stiffness increase factors, which could be used for the engineering design of CLT connections.
Networks for Innovation – But What Networks and What Innovation?

Innovation is a social and interactive process in which collaboration and exchange of knowledge and information play crucial roles. Two conflicting hypotheses have been raised in previous research: Burt's structural hole hypothesis and the density hypothesis. In brief, the former of these hypotheses builds upon arguments for open network structures in the acquisition of innovation; the latter one builds upon arguments for closed network structures for innovation. To shed some light on this state of confusion, this paper tests these two conflicting hypotheses on two separate measures of innovation in a service industry setting. One innovation measure is more incremental in nature and regards the implementation of employees' ideas. The other innovation measure is more radical in nature and regards new services. Findings suggest that social network measures are, indeed, powerful predictors of innovation and, further, that the impact of these are likely to be radically different depending upon the type and measure of innovation. Consequently, this paper recommends caution when studying the impact of social network measures upon innovation, and that more fine-grained measurements in particular are needed rather than focusing upon inter-relationships of an overly general and superficial nature.
Eastern Red Bat Responses to Fire during Winter Torpor

Prescribed fires are a forest management tool used to improve natural areas for a variety of benefits including increased plant diversity, reduced competition for desired species, decreased fuel loads, and improved wildlife habitat. The post-fire results in landscapes have shown positive benefits for bat populations. However, prescribed fires set in the winter may cause direct mortality of eastern red bat (Lasiurus borealis) populations that use leaf litter for roosting during periods of colder (<10 °C) temperatures. Therefore, we used controlled laboratory techniques to explore if eastern red bats arouse from torpor when exposed to cues associated with fire (i.e., smoke and the sound of fire). Through subsequent field trials, we confirmed latencies of first response (i.e., movement or increased respiration), arousal, and flight behaviors to the stimuli of fire. We provide evidence of smoke influencing eastern red bat first response and arousal through laboratory and field trial results. Latencies of all behaviors were negatively correlated with temperatures and wind speeds prior to and during field trials. We recommend prescribing winter fires on days when temperatures are >10 °C to provide eastern red bats with a better chance to passively rewarm and react to an approaching fire.
Paradigmi dell'intervento pubblico e politica italiana dei trasporti: una rilettura critica

Paradigmi dell'intervento pubblico e politica italiana dei trasporti: una rilettura critica (di Gerardo Marletto) - ABSTRACT: The aim of the paper is to reconsider the Italian transport policy. First, the six main transport policies implemented in Italy since the sixties are deeply analysed: building of infrastructure; supply of public services; promotion of competition; reduction of external costs; internationalisation; promotion of innovation. Then, they are compared using four Kuhnian paradigms of state intervention in the economy. Finally, two conclusions come out: 1) the today prevailing competitive paradigm is not adequate to promote and to make viable the creation of new transport systems; 2) there is a need to explicitly refer to structural and dynamic paradigms as the theoretical foundations of an entirely new transport policy.
Domesticating Neoliberalism: ‘Domification’ and the Contradictions of the Populist Countermovement in Poland

Abstract This essay asks whether Poland’s populism is evidence of a countermovement to European neoliberal political economy. The electoral success of PiS’s 500+ child benefit policy appears to indicate that state intervention in the form of solidarism is a legitimate response to neoliberalism. The essay argues against this. Taking domification (drawing on the Polish word for home, indicating a shift to greater social solidarism) as a starting point of analysis, it interprets 500+ as a way to co-opt particular social forces to accept the promotion of neoliberal competitiveness in Poland. What at first appears to be a progressive alternative is, in reality, a contribution to further commodification of the reach of capital enabling the reproduction of neoliberalism.
Synthesis and Characterization of Silver Nanoparticles Prepared with Carrasquilla Fruit Extract (Berberis hallii) and Evaluation of Its Photocatalytic Activity

In this study, silver nanoparticles (AgNPs) were obtained using a green-chemistry procedure. For this protocol, the Carrasquilla extract (CE) (Berberis hallii) and a AgNO3 solution were used as the reducing agent and the metal precursor, respectively. The as-prepared AgNPs after characterization were then used to evaluate the degradation of the methylene blue (MB), the safranin (SF), and the mixture of both dyes in the aqueous phase under solar light irradiation. The photocatalytic activity of AgNPs for the degradation of the MB (k = 0.0092 min−1) was higher than the SF (k = 0.00016 min−1) due to the susceptibility of the thiazine ring of the MB to photodegradation contrasted to the phenyl phenazine of the SF. However, SF was mostly removed by adsorption with a maximum uptake of 2907 mg/g. Overall, this eco-friendly and green conversion of silver ions to metallic elements avoids the use of toxic chemicals and could be applied for the degradation/adsorption of dyes used in several industrial processes.
Creativity as social and spatial process

Purpose – This paper seeks to argue that creativity in the workplace is a very complex construct that is difficult to measure not only in its own right, but also in its interrelation with physical space. Since creativity is a social process, this paper aims to suggest studying interaction patterns as a fundamental feature of creativity.Design/methodology/approach – Based on the literature, two criteria for creativity in workplaces were developed: spaces for chance encounters with people from different teams; and a balance of spaces for communication and concentration. Using a mixed‐methods research design, a UK media company was studied before and after a relocation and refurbishment project in 2007‐2008. The case study included structured interviews, satisfaction surveys, social network surveys, space observations, and a Space Syntax analysis of floor plans.Findings – The paper showed that only the first criterion was successfully met in the media company studied, and that the pressure on the industry in.
Frequency of Irrigation and Boron on Growth, Yield, Water Use Efficiency and Economics of Summer Green Gram in Humid Sub-Tropical Climate

ABSTRACT Green gram is responsive to irrigation and boron application. The field experiments comprising of three irrigation frequencies (I1 = branching, I2 = branching + flower initiation, and I3 = branching + flower initiation + pod development) and four borax levels (B1 = soil applied at 10 kg/ha, B2 = 0.2% foliar spray at branching, B3 = 0.2% foliar spray at flowering, and B4 = 0.2% foliar spray at branching + flowering) were conducted in a humid sub-tropical climate of India during two consecutive seasons of 2018 and 2019 to optimize irrigation and boron (B) requirements for the plant. Results showed that maximum growth and yield constituents were found in I3 and B4. Mean maximum seed and stover yield and highest accumulation of N, P and K in plant and B in seed and stover were noticed in I3B4. Maximum water use efficiency (9.10 kg/ha-mm) was displayed in I1B4. Maximum nodulation was found in I2B1 and I3B1. The highest gross return, net return and BCR were obtained in I3B4. Thus, irrigation at branching, flower initiation and pod development stage coupled with 0.2% B foliar application at branching and flowering stage was observed the as best treatment combination for deriving maximum growth, yield, yield constituents, nutrients uptake and economics of summer green gram.
