Previous literature suggests that in masculinized domains, a stereotypical portrayal of women has a negative impact on society’s perception of them. However, the influence of media representation on people’s perceptions of athletes depending on their gender, as well as its possible consequences for both men and women, remains unexplored in the sports sphere. Through two experimental studies employing a scenario methodology, we aimed to address this gap in the literature: In Study 1 (N = 190), we tested the influence of the media’s representation (focused on the professional field vs. extraprofessional field) and the athlete’s gender (man vs. woman) on perceptions, and in Study 2 (N = 625), we examined the effect of gender for an athlete receiving media coverage focused on the extraprofessional field. Study 1’s results showed that when media representation was based on the professional (vs. extraprofessional) field, participants perceived the news as more credible, believed that the media valued the athlete’s capacity to a greater extent, and attributed more merit to the athlete. Moreover, Study 2, focused on an extraprofessional field, indicated that when a man athlete (vs. woman athlete) was portrayed, participants were more likely to consider the news content accurate, which, in turn, was associated with a higher attribution of competence to the athlete and a higher intention to consume sports media in the future. The study will hopefully help reduce beliefs about existing stereotypes as well as discrimination against women, whether in sports or in any other field (e.g., professionally or in education).

Clays are involved in a variety of natural and managed processes, and calculation of their stability conditions is important. Such calculations are still fraught with large uncertainties owing to the lack of experimental constraints on the thermodynamic properties of clays, and bracketing of equilibrium reactions at low temperature is barely possible. Experiments aimed at studying the thermal stabilities of, and composition-temperature relations among, smectite, illite, kaolinite, pyrophyllite, mica, and chlorite at different levels of SiO2, K2O, MgO, and Al2O3 species in solution were conducted under a strong thermal gradient in the simple K2O-Al2O3-SiO2-H2O (KASH), MgO-Al2O3-SiO2-H2O (MASH), and KMASH systems. The crystallization series observed in the different experiments match to some degree those observed in active geothermal systems where clay minerals precipitate from oversaturated solutions. Smectite and/or ordered mixed-layer materials, smectite-donbassite, or possibly pyrophyllite-donbassite were observed to crystallize in both KASH and MASH experiments. Similar crystallization sequences and clay composition variations with temperature were observed in most cases when the relative positions of the starting solids were switched. The experimental results were used to refine the thermodynamic properties of K- and Mg-smectite. Stability diagrams calculated by energy minimization and activityactivity diagrams are consistent with the experimental mineral variations, suggesting that smectite is thermodynamically stable at temperatures as high as 300°C in the presence of diluted water and quartz and K-feldspar-free systems.

Women who ran for office in 2018 used a variety of strategies on the campaign trail, with some highlighting more masculine traits and others more feminine traits, but the latter was more common than in prior years. We ask how effective these strategies are for trait evaluations, perceptions of leadership and competence, likeability, and vote choice and how this effect varies based on respondent’s views about the role of women in society. To explore these relationships, we use data from a two-wave panel conducted in the winter of 2019. Results from our experiment show that female candidates who highlight more masculine traits are perceived as more agentic, less communal, and more competent, and, importantly, they do not appear to suffer from a backlash effect. Those higher in sexism also evaluate women who display these qualities as more competent, though as less warm and likable.

Many governments invest public funds in communication interventions and campaigns against prostitution and sexual exploitation in an attempt to change attitudes toward prostitution and eventually decrease its consumption. Despite the considerable investment that public institutions have made in campaigns against prostitution and sexual slavery, no known empirical studies have evaluated the effectiveness of such campaigns on attitudes and behavioral change. The messages of these campaigns usually center on one of two thematic focuses: Prostituted women who suffer exploitation and male consumers of prostitution. The present study examines the impact of different anti-prostitution advertisements on attitudes among male participants (N = 155 male participants). Specifically, the experiment aims to test the differential effect of these two focuses, compared to a no-advertisement control condition, on social support for prostitution, negative and incorrect beliefs about prostitutes, and family values related to prostitution. The results show that compared with the no-advertisement control condition, advertisements focused on men who use prostitutes have a significant effect on social support toward prostitution and incorrect beliefs about prostitutes, whereas advertisements focused on female prostitutes have no effect. The results have practical implications for governments and councils regarding the efficacy of this kind of public communication campaign against prostitution consumption.

The objective of this work was to assess whether the implementation of a bridge resource management (BRM) unit into the simulator-based nautical training of the German Navy is effective in improving non-technical skills and navigation performance. To this end, questionnaire data, observations of behaviour and performance outcomes were compared between a control group and an experimental group. Data of 24 bridge teams (126 sailors) were used for the analyses. Ten teams received BRM training and 14 teams served as the control group with unchanged simulator training. Reactions to simulator training were positive in both groups but more favourable in the control group. In the BRM group, significantly more positive attitudes towards open communication and coordination, more frequent sharing of information and fewer collisions were found than in the control group. Effect sizes were rather small. This may be due to the limited scale of the BRM unit, which consisted of only one instruction-training-feedback cycle. The extension of BRM-related feedback to all simulator runs of the nautical training can be expected to produce larger effects on attitudes, behaviour and performance.

Herbal medicinal products have been traditionally used for the treatment of minor sleep disorders and mild anxiety symptoms. However, prospective clinical studies are scarce, due to a number of variability factors such as population heterogeneity and a strong placebo effect. To overcome these limitations, animal models are available that provide unbiased scientific results.

In this study, we examined the effect of an association of four compounds [namely Melissa officinalis, Crataegus oxyancantha, calcium lactate and magnesium thiosulfate (32/30/32/6; w/w)], on several behavioral tests in rodents. Animals were tested for general activity on an automated actimetry system, and for anxiety on the so-called “staircase test”.

In the actimetry test, adult mice were placed in an empty cage and their spontaneous level of activity (distance travelled and the number of rearings) was measured after an intraperitoneal administration of 25, 50 or 75 mg/kg of the association. A dose-dependent decrease of the distance travelled and number of rearings was observed after administration (statistically significant at the dose of 75 mg/kg). In the staircase test, the number of rearings (a measure of anxiety) and the number of steps climbed (general activity) were measured. A statistically significant decrease in the number of rearings was observed at the dose of 25 mg/kg (compared to vehicle-treated animals), whereas no effect in the number of steps climbed was observed at the same dose. These results suggest that the association could induce an anxiolytic effect. At higher doses, a sedative effect was observed.

In conclusion, the administration of an association of Melissa officinalis, Crataegus oxyacantha, calcium and magnesium induced a clear dose-dependent sedative effect in mice. One test suggests that this association could also have anxiolytic properties. This study confirms that herbal medicinal products could be a beneficial treatment for minor sleep disorders or mild anxiety symptoms.

In this article we investigate the role of semantic relations in grammatical alternations. The specific alternation we look at is that between the proper name modifier construction, e.g. the Obama government, and the determiner genitive, e.g. Obama's government. Through the use of an experimental study in which participants were asked to rate the naturalness of the two constructions in 20 attested natural language contexts and provide paraphrases of the semantic relations in question, we tested when the two constructions alternate and whether either construction expresses semantic relations that block alternation. Our initial finding is that none of the relations we studied is categorically associated with only one of the constructions, but that certain relations – notably possession and name – are far more preferentially associated with determiner genitives and proper name modifiers respectively. Despite these ‘default’ associations, participants nevertheless identified a range of possible interpretations for many of the examples, meaning that our study simultaneously supports the opposing theoretical views of default relations and semantic underspecification. Further, our study validates the inclusion of semantic relations in genitive alternation studies as a major factor despite the notorious difficulties in their operationalisation. Animacy distinctions, although more straightforward to codify, appear to be of lesser importance. Methodologically, our study shows the value of an experimental approach as a corrective to researcher intuitions about the identification of semantic relations in context.

A new solver is developed to numerically simulate the melting phase change with natural convection. This solver was implemented on a single Nvidia GPU based on the CUDA technology in order to simulate the melting phase change in a 2D rectangular enclosure. The Rayleigh number is of the order of magnitude of 108 and Prandlt is 50. The hybrid thermal lattice Boltzmann method (HTLBM) is employed to simulate the natural convection in the liquid phase, and the enthalpy formulation is used to simulate the phase change aspect. The model is validated by experimental data and published analytic results. The simulation results manifest a strong convection in the melted phase and a different flow pattern from the reference results with low Rayleigh number. In addition, the computational performance is estimated for single precision arithmetic, and this solver yields 703.31MLUPS and 61.89GB/s device to device data throughput on a Nvidia Tesla C2050 GPU.

The value of sketching in engineering design has been widely documented. This paper reviews trends in recent studies on sketching in engineering design and focuses on the encouragement of sketching. The authors present three experimental studies on sketching that look at (1) sketching assignments and their motivation, (2) the impact of a sketching lesson, and (3) the use of Smartpen technology to record sketching; overall these studies address the research question: Can sketching frequency be influenced in engineering education? Influencing sketching frequency is accomplished through motivation, learning, and use of technology for sketching, respectively. Results indicate that these three elements contribute to the encouragement of sketching in engineering design.

Nanocomposites with platelet reinforcements are emergent materials whose deformation mechanisms still need to be carefully investigated. In this study, we first present the studied class of nanocomposites (Polypropylene reinforced by Montmorillonite clay nanoplatelets). From uniaxial tensile tests, it is shown that some mechanical characteristics of the nanocomposite (Young's modulus, yield stress) significantly increase compared to the matrix even for very low volume fraction of reinforcements (maximum of 7% mass fraction for our tested specimen). The Ponte Castañeda and Willis [6] bound is adopted to account for the evolution of the elastic behavior of the material [7]. Adapting the Hill-type incremental method [13] allows the simulation of the non linear behaviour of the material. However, it is shown that this scheme requires careful choice of the aspect ratio, in the plastic domain, to provide good predictions of plasticity.

For performance-based seismic engineering of buildings, the direct displacement-based seismic design method is different from the coefficient method used in FEMA-273 and the capacity spectrum method adopted in ATC-40. The method not only is a linear static procedure but also is applied to the design of new constructions. This paper concerns with experimental studies on the accuracy of the direct displacement-based design procedure. Experimental results of three reinforced concrete (RC) columns designed by the displacement procedure are presented and discussed through pseudo-dynamic tests and cyclic loading tests. From the tests, it is shown that the stiffness degrading factor of RC columns plays a key role. The direct displacement-based seismic design method can reliably capture the maximum displacement demand of the test RC columns if the stiffness degrading factor adopted in the displacement design method for RC material is adequate.
