Feminist Beliefs, Not Gender Equality Primes, Shape Self-Reported Partner Preferences

AbstractMen are reported to prioritise physical attractiveness in potential intimate partners, while women focus on the abilities of potential partners to provide resources. Yet previous research has suggested that these traditional gender differences vary according to national levels of gender equality. Here, we used priming material to manipulate participants’ perceptions of gender equality and examined the effects on self-reported partner preferences, and we also investigated the association between participants’ gender role attitudes and partner preferences. In Study 1 and 2 (n = 224 and 380), participants were presented with priming material that focused on either inequality between the genders in the present day (Inequality Condition) or recent improvements in gender equality (Equality Condition). Contrary to our predictions, the importance that participants placed on the physical traits and resource-gaining potential of partners did not differ between conditions in either study. However, on average, men placed greater emphasis on physical traits and preferred younger partners, and women placed greater emphasis on resource-gaining characteristics and preferred older partners, in line with previous research. In addition, men who reported more positive feminist attitudes placed less emphasis on physical traits, and women who reported more positive feminist attitudes placed greater emphasis on kindness, compared to same-gender participants who scored lower on feminist attitudes. This research suggests that self-reported partner preferences are related to an individual’s feminist attitudes and highlight the challenges of exploring these associations with forced-choice and experimental priming designs.

Assessment of merits and demerits of perpendicular and slanted photovoltaic/thermal facades

This study compares the thermal and electrical energy production potential and wind load assessment of perpendicular versus slanted photovoltaic (PV) facades. The goal is to identify the optimal facade orientation for societal adoption based on energy efficiency and wind load considerations. Using Hybrid RANS/LES models, the aerodynamic performance and energy yield of both orientations are analyzed under varying angles and environmental conditions. The findings show that while the slanted façade is better designed to capture solar irradiance, it produces 4 to 8 % less energy than the perpendicular façade and yields approximately 2 % less exergy efficiency due to wind regime. However, the slanted design reduces wind load by 9.8 %, enhancing structural stability. The maximum thermal energy output of 217 kW is recorded from the perpendicular façade at a wind speed of 1 m/s, while the slanted façade generates a peak electrical power of 68 kW at 8 m/s wind speed. Overall, the perpendicular façade underscores more efficient in equal weather conditions, making it a sustainable choice for PV installation. These results provide valuable insights for architects, engineers, and policymakers in optimizing PV facade design for urban environments.

The Multiplicity of Abortion Pills: Considering the Public Constructions of ru486 in Sweden

Abstract To this day, abortion pills are a contentious technology – used freely and legally in some countries while prohibited in others. Previous scholarship has shown abortion pills to be difficult to integrate into medical systems. Available since the early 1990s, little has been written on the early adoption of abortion pills in Sweden, one of the first countries to register the compound ru486 for use. This is remarkable if we consider what is at stake when introducing new abortion technologies – namely, the conditions for gender equality and the very tangible implications for maternal health. This article examines the Swedish process of acquiring ru486: mapping the varied actors invested in its use, and analysing the different constructions of abortion pills that were made in these networks. It argues that earlier reproductive research initiatives and their extensive press coverage helped to make registration possible for ru486 in the early 1990s. Comparisons between the constructions of ru486 in Canada and the U.S. illustrate a few key differences between the countries and show why, despite many similarities, Sweden was the first to officially acquire the drug.

Bulk acoustic wave—Solidly mounted resonator with a-SiOCN:H as low-Z material

Bulk acoustic wave (BAW) filters have been proven to be of high demand in today's low power RF front-ends for mobile communication devices. Within the launch of 5G applications worldwide, especially in the region of new radio (nr-1) up to 6 GHz, defined frequency bands require filters of wide bandwidths, while simultaneously featuring steep edges and high out-of-band rejection. Due to the coexistence with 4G LTE (long term evolution) wireless standards as well as advanced data transfer concepts such as carrier aggregation, the increasing complexity of antenna systems forces the implementation of highly selective acoustic filters. In contrast to the widely used surface acoustic wave (SAW) technology, BAW filters appear with superior performance for frequencies above 1 GHz. This work describes the fabrication of a BAW-solidly mounted resonator (BAW-SMR) with a tailored material system of a-SiOCN:H as a low impedance (low-Z) material integrated within its acoustic Bragg mirror. A direct comparison to the widely used low-Z material of SiO2 with an acoustic impedance of around 13 MRayl is demonstrated by two equal resonator stacks by replacing only the uppermost low-Z thin film of the acoustic reflector. A single-mask design was chosen with platinum as a bottom electrode to ensure the most equal growth conditions for the piezoelectric aluminum nitride (AlN) layers on both reflectors’ surfaces featuring either the tailored a-SiOCN:H or standard SiO2. The a-SiOCN:H thin films were deposited by plasma-enhanced chemical vapor deposition and the according acoustic impedance was priorly depicted to 7.1 MRayl, which could be exploited to achieve an increase in the effective coupling coefficient beyond 7% as well as a resonator bandwidth of more than 60 MHz.

Institutional policies and practices to improve access and success in higher education: the students’ proposals

ABSTRACT Ensuring equal conditions of access and success for all higher education students is a challenging task for educational systems and institutions. Understanding the students’ perspectives and needs regarding educational policies and institutional practices in higher education can be an important contribution to improving the quality of education. This paper aims to identify the main obstacles faced by students and their proposals for the improvement of policies and institutional practices in the Portuguese higher education system to promote access and success for all students. By using a mixed-methods approach, we gathered responses from 1,292 students enrolled in 56 HEIs. Data was analysed through content analysis with a pre-existing grid comprising three dimensions: socio-economic, educational and institutional. Descriptive statistics were carried out for the quantitative data. The results revealed socio-economic factors were the most frequently mentioned as needing improvement, followed by the educational and institutional factors. The results allow concluding that institutional practices and educational policies are directly related. Thus, the institutional and political improvement actions should be seen in a holistic and integrative way, integrating actions to enhance the students’ socio-economic, educational and institutional conditions.

Geodesic connectivity and rooftop envelopes in the Cegrell classes

AbstractThis study examines geodesics and plurisubharmonic envelopes within the Cegrell classes on bounded hyperconvex domains in $$\mathbb {C}^n$$ C n . We establish that solutions possessing comparable singularities to the complex Monge–Ampère equation are identical, affirmatively addressing a longstanding open question raised by Cegrell. This achievement furnishes the most general form of the Bedford–Taylor comparison principle within the Cegrell classes. Building on this foundational result, we explore plurisubharmonic geodesics, broadening the criteria for geodesic connectivity among plurisubharmonic functions with connectable boundary values. Our investigation also delves into the notion of rooftop envelopes, revealing that the rooftop equality condition and the idempotency conjecture are valid under substantially weaker conditions than previously established, a finding made possible by our proven uniqueness result. The paper concludes by discussing the core open problems within the Cegrell classes related to the complex Monge–Ampère equation.

Numerical study of influencing geometry of separator elements for cleaning dust of food production on its efficiency

At modern food enterprises, the task of providing high-quality air cleaning from dust is relevant. The paper proposes an original dust separator, the peculiarity of which is the presence of structural elements of different shapes, arranged in a chess order. This design solution ensures the formation of a wave-like structure of the gas-dust flow within the device. The separation of solids from air is due to inertial and centrifugal forces. The aim of the work is to evaluate the fractional efficiency of this separator with structural elements of different geometric shape during the dust capture process. The paper considers I-shaped, P-shaped, arc-shaped and V-shaped structural elements. The study is carried out by numerical simulation at a gas dust flow rate of 0.5 to 3 m/s and a particle size of 10 to 200 ?m. During the work it has been found that the shape of the structural elements largely determines the efficiency of separation of dust material from the gas stream. The V-shaped design elements have shown the highest average separation efficiency compared to other shapes under other equal conditions. This is due to the fact that in such a separator the particles are directed to their apex, where the velocity of the particles decreases contributing to their subsequent settling into the bunker. The maximum efficiency for V-shaped elements is on average 80.1 % at a gas dust inlet velocity of 0.5 m/s. The lowest efficiency is observed for I-shaped elements, as particles return to the air stream after rebounding from the walls.

La garantía del debido proceso y la práctica de la prueba en las audiencias telemáticas

The implementation of telematic hearings during the pandemic has been a valuable tool to connect the procedural parties with the judge, streamlining judicial procedures. However, this change presents challenges in terms of respecting due process guarantees, especially in terms of authenticity of information and protection of personal data. Due process guarantees respect for the fundamental rights of people and regulates judicial acts and procedures. The implementation of telematic hearings has raised concerns about the technical quality of the connection, the security of the information and the lack of physical interaction to evaluate the credibility of the testimonies. The research methods used include observation to determine regularities in the hearings, bibliographic review to analyze relevant documents, and expert judgment through interviews and surveys. Likewise, methods such as analysis-synthesis and inductive are used to delve into the impact of procedural guarantees, lege ferenda to propose legal modifications, and historical-logical to evaluate compliance with guarantees and possible solutions. To address these concerns, a modification to the General Organic Code of Processes is proposed, establishing clear protocols that include verification of the identity of the declarant, the prohibition of reading notes during the declaration, and the possibility of applying additional verification in case of measures of doubts about the authenticity of the information. The proposal seeks to guarantee the integrity of the judicial process in telematic hearings, ensuring respect for the principles of due process and equal conditions for all parties involved.

Effects of Surface Crack Shape on Fracture Behavior of Oil Pipelines Based on the MMC Criterion.

This study employs a hybrid numerical-experimental calibration method based on phenomena to determine the fracture parameters of the Modified Mohr-Coulomb (MMC) model. Using a self-developed VUMAT subroutine and the element deletion technique, the fracture process of a wide plate pipeline is thoroughly analyzed. This study investigates the impact of various crack shapes on the fracture response under tensile loading and the influence of surface crack size on the initiation location of a wide plate. These results demonstrate the calibrated MMC fracture model's accurate prediction of the toughness fracture behavior of X80 pipeline steel. Under equal area conditions of the dangerous section, circular cracks exhibit lower bearing capacity compared to elliptical cracks. Elliptical cracks predominantly propagate in the thickness direction, whereas circular cracks show nearly uniform growth in all directions. Furthermore, when the crack depth is less than half of the wall thickness, the damage accumulation value at the midpoint of the crack front is maximized; conversely, when the crack front is closer to the internal measurement point of the wide plate, the damage accumulation value is maximized.

Management of Agile Methodologies for the Development of Competencies of University Students in the Peruvian Context

The fundamental purpose of this research work was to explain how the management of agile methodologies for the development of competencies of university students in the Peruvian context. Based on this question, it has been hypothesized that agile methodologies significantly help the development of students' competencies. This is complemented by a quantitative approach study, with a quasi-experimental design of the "Design with pre-test - post-test with experimental groups and control groups" model. The students of the one Peruvian University were considered as the study population, of which the students of the Faculty of Initial Education were taken as a study sample, within which 100 students participated as an experimental group. 100 from V, VII, X cycle and as a control group 100 students from II, III, and IV cycle respectively. Therefore, as the main result, it is evident that, with a bilateral significance of .000 less than the predetermined significance of 0.05 and a result of F = 1.013, they confirm that the first condition of equality of variances is met and thus establish the Test of the General Hypothesis or HG according to the normal "Z" equal to 8.965, in the case of two independent samples and a difference of 3.81 plus Gl = 51 degrees of freedom and assuming a 95% confidence level, the hypothesis is rejected null and the alternative Hypothesis is accepted, concluding that agile methodologies significantly help the development of students' competencies with a significance of pv ,000..

The prospects for the use of alternative gel formers for hydraulic fracturing

The article discusses the relevance of using alternative gel-forming agents in the preparation of fracturing fluids for hydraulic fracturing (HF). Besides the obvious tasks, such as increasing the residual conductivity of the fractures created during stimulation, it also addresses the impact of alternative gelforming agents on the treatment process. The author, supported by field data, concludes that under otherwise equal conditions, replacing traditional fracturing fluids with alternative ones significantly reduces frictional pressure losses in the pipes, which is particularly important when treating deep and extensive horizontal wells with limited internal pipe diameters. Moreover, the aforementioned impact of gel-forming agents on frictional pressure losses allows for a reserve of power in the hydraulic fracturing fleet equipment. Consequently, the treatment can be performed with higher flow rates under otherwise equal conditions, without the need for additional high-pressure pumps or the deployment of more expensive, stronger, larger-diameter tubing. Another important conclusion reached by the author is that due to the specific properties of alternative fracturing fluids, their ability to transport and retain proppant is significantly increased. This property of fracturing fluids is especially important when treating low-permeability, fractured formations and during the stimulation of long horizontal wells. On the other hand, the use of alternative gel-forming agents raises the requirements for the controlled breakdown of fracturing fluids, complicating the task of selecting a rational formulation and necessitating additional research.

Heterogeneous degradation of chloramphenicol antibiotic by peroxymonosulfate activated by FeS and FeS2: Mechanism and effects of catalysts dosage and pH

Antibiotics in the environmental waters pose long-term threat to ecological safety because of their persistent and potential toxic nature. FeS and FeS2 were proved to be efficient catalysts for the activation of peroxymonosulfate (PMS) and the generation of sulfate radical generation for refractory pollutant degradation. However, their performance for antibiotic degradation has not yet been comparatively and comprehensively investigated. Herein, the FeS/PMS and FeS2/PMS systems were developed to explore chloramphenicol (CAP) degradation under equal conditions. The results show that CAP was efficiently degraded in both two systems, with a removal efficiency exceeding 90 % within 120 min using 6 mM PMS and 0.6 g/L catalysts.Acceleration in degradation rate was observed in the FeS2/PMS system when the catalyst dosage ranged from 0.1 g/L to 1.0 g/L (constant PMS concentration) with a reaction rate constant (kobs) of 2.1-fold higher than that in the FeS/PMS system. However, the kobs were comparable with the PMS concentration range (constant catalyst dosage) in the two systems, suggesting that the catalysts were the rate-limiting step in CAP degradation process. The initial pH strongly affected CAP degradation in the FeS/PMS system but had little effect on that in the FeS2/PMS system. Surface Fe2+ played a dominant role in PMS activation, and S22−/S2− facilitated Fe2+ regeneration. Further, both FeS and FeS2 had stable activity for PMS activation during long-term use. This study proves the effectiveness of FeS and FeS2 for PMS activation for antibiotic degradation and differentiates their catalytic qualities, which will provide alternative heterogeneous catalysts for practical application.

Research on the Application of Cushion and Isolation Materials in Protecting the over Shield Tunnel

The portal frame, as an innovative subway protection structure, primarily serves the development of underground spaces above shield tunneling for subways. It comprises foundation piles along both sides of the tunnel and a transition thick plate. When the transfer thick plate sustains loads at its midspan, deformation occurs, interacting with the underlying soil to generate additional stresses, thereby potentially impacting the subway tunnel beneath negatively. This study, anchored in the real-case scenario of Qianhai Exchange Square, employs finite element analysis to investigate the interaction mechanisms between the transfer thick plate under midspan loading and soils of varying properties. Findings revealed a characteristic distribution pattern of additional stresses in the soil—smaller at the edges and larger at the center. Furthermore, under equal loading conditions, there's a positive correlation between soil stiffness and induced additional stress, while an inverse relationship exists with the vertical deformation of the transfer thick plate. In response to this issue, the paper innovatively proposes embedding a cushioning and isolation layer under the transfer thick plate. Based on the results of full-scale tunnel tests carried out during the early stages of the project, and by employing high-precision finite element simulations, the bearing capacity of the tunnel was determined. This analysis, in turn, informed the formulation of selection principles for the cushioning and isolation materials in a feedback manner. Computational verifications showed that appropriately designing the cushioning and isolation layer can significantly reduce additional stresses in the foundation soil, thereby effectively alleviating the impact of concentrated upper loads on the shield tunnel.

Four new ruthenium(II) coordination compounds bearing coumarin derivatives as anticancer agents

Toward the development of effective metal-based coordination drugs for the treatment of cisplatin-resistant cancers, we report four new ruthenium(II) coordination compounds, namely, [RuCl2(yc1)2(DMSO)2] (QY1), [RuCl2(yc2)2(DMSO)2] (QY2), [RuCl2(yc3)2(DMSO)2] (QY3), and [RuCl2(yc4)2(DMSO)2]·1.25H2O (QY4), which contain 3-pyridin-2-yl-chromen-2-one (yc1), 8-methyl-3-pyridin-2-yl-chromen-2-one (yc2), 7-methoxy-3-pyridin-2-yl-chromen-2-one (yc3), and 2-pyridin-2-yl-benzo[f]chromen-3-one (yc4) ligands, respectively. Complex QY4 possessing a more extended planar yc4 ligand showed the highest cytotoxicity against cisplatin-resistant A549/DDP lung cancer cells (R9LC), yielding a remarkably low micromolar IC50 value of 5.02 ± 0.14 μM and low toxicity against embryonic kidney HEK293 (e293) normal cells under equal conditions (IC50 = 88.04 ± 1.03 μM). Notably, QY4 exhibited higher cytotoxicity than QY1–QY3, yc1–yc4, and cisplatin. QY4 and QY1, especially QY4, induced R9LC apoptosis via mitochondrial dysfunction, which involved mitochondrial membrane potential (MP) damage, ROS/Ca2+ activation, and apoptosis protein up-regulation. Thus, these coumarin ruthenium(II) coordination compounds are promising mitochondria-targeting anticancer agents.

The Distributive Demands of Relational Egalitarianism

AbstractThe article outlines the distributive demands of relational equality in the form of a dynamic corridor of legitimate distributive inequality. It does so by complementing the already widely accepted sufficientarian floor with a limitarian ceiling, leading, in a first step, to a "corridor" of limited distributive inequality as a necessary condition for relational equality. This corridor alone, however, only provides necessary distributive conditions for relational equality and still allows for degrees of distributive inequality that would risk undermining egalitarian relations. Thus, in a second step, intra-corridor distributive inequalities must be regulated by two further constraints: a (context- dependent) ratio between the best- and worst-off, and a demand for equality of opportunity so that inequalities result from people’s responsible choices. This set of demands spells out the distributive conditions that are not only necessary, but sufficient to provide a sound distributive basis for relational equality. After presenting this view, the article defends it against several objections.

Differing temperature dependencies of functional homologs zebrafish Abcb4 and human ABCB1.

The ATP binding cassette (ABC) transporters human ABCB1 and zebrafish (Danio rerio) Abcb4 are functionally homologous multixenobiotic/multidrug (MXR/MDR) efflux transporters that confer the efflux of a broad range of diverse chemical compounds from the cell. As ATPases, the transporters utilize the energy released by ATP cleavage for protein conformation changes and concomitant active transport of substrate compounds. The temperatures, at which human ABCB1 and zebrafish Abcb4 need to function, can substantially differ: Whereas the ambient temperature of human ABCB1, which is that of the human body, is constant, zebrafish Abcb4 has to be active in a wider temperature range as the body temperature of zebrafish can considerably vary, depending on the ambient water temperature (18°C-40°C). Here, we examined the effect of temperature on the ATPase activities of recombinant human ABCB1 and zebrafish Abcb4 generated with the baculovirus expression system. Incubation temperatures for enzyme reactions were set to 37°C and 27°C, corresponding to the human body temperature and the cultivation temperature of zebrafish in our lab, respectively. For stimulation and inhibition of zebrafish Abcb4 and human ABCB1 ATPase activities verapamil and cyclosporin A were added at different concentrations and 50% effect concentrations (EC50) were determined. The different temperatures had a stronger effect on the human ABCB1 than on the zebrafish Abcb4 ATPase: Differences between EC50 values for verapamil at 37°C and 27°C, respectively, were 1.8-fold for human ABCB1 but only 1.2-fold for zebrafish Abcb4. Activation energies (Ea) of basal and verapamil-stimulated ATPases, calculated based on the Arrhenius equation, were 2-fold (basal) and 1.5-fold (verapamil-stimulated) higher for human ABCB1 than for zebrafish Abcb4. The differences between zebrafish Abcb4 and human ABCB1 ATPases in temperature sensitivity and activation energy could be important for the comparison of the functional properties of the two transporter proteins in the context of pharmaco-/toxicokinetics. Related to this, our finding that at equal reaction conditions the zebrafish Abcb4 ATPase activity tended to be generally higher than that of human ABCB1 may also be important, as this may point to a higher substrate compound transport rate of Abcb4.

When the hunter plays the hunted: heterosexual Chinese women’s negotiations with hegemonic sexual scripts on dating apps

ABSTRACT Sexual scripts are the behavioral patterns in people’s performance of sexualities. As hegemonic patriarchal sexual scripts assign submissive roles to women in heterosexual intimacy, this study explores how heterosexual women can take a proactive role in online dating with the aid of dating app affordances. Based on interviews with 18 heterosexual women living in urban China, our findings show that women can strategically craft their user profiles to not only attract certain types of men they desire, but also filter out undesirable men. They can use the topics they extract from men’s profiles to take the initiative to start conversations with men when they are willing to. By switching media platforms and/or communication modalities, they can fuel relationship development. Meanwhile, they manage sexual risks through communication with their dates about sex and precautions against unexpected situations in hook-ups. They have also created positive meanings for casual sex: They regard women’s right to engage in hook-ups as a condition for gender equality, perceive casual sexual relations as a form of meaningful social connection, and endow such relations with romantic potential. They may also hold positive attitudes toward their dating app use, as they may have derived confidence and sociability from it.

Syndiotactic chiral metastructure with local resonance for low-frequency vibration isolation

Isolating low-frequency vibrations is a challenge in engineering due to their long wavelength. The bandgap within inertial amplification metastructures has proven to be an effective solution for isolating low-frequency vibrations. In this study, a chiral local resonator is proposed and integrated into a syndiotactic chiral inertial amplification metastructure (SCM) to create a low-frequency bandgap. Under equal mass and stiffness conditions, SCM-CR exhibits a bandgap starting frequency 32.3 % lower than that of traditional metastructures with traditional local resonators (TM-TR), and the normalized width of the bandgap is 31.7 % wider than TM-TR. The low-frequency bandgap is attributed to the presence of chiral local resonators. The inertial amplification effect induced by the chiral structure results in a resonance frequency lower than that of local resonators with equivalent mass and stiffness. Within the low-frequency bandgap, the transmission of the SCM-CR proposed in this study exhibits double attenuation notches over a specific number of periods, leading to the normalized width of the deep attenuation region 45.8 % broader than that of traditional metastructures with chiral local resonators (TM-CR). The tunability of the bandgap has also been investigated. Experimental results verified the double attenuation notches and the tunability of the bandgap. This work provides a promising solution for low-frequency vibration isolation.

Are real-time volunteer apps really helping visually impaired people? A social justice perspective

While digital technologies have undoubtedly enhanced the quality of life for individuals with visual impairment, their influence on social justice remains underexplored. Drawing upon intergroup contact theory, this study employs a mixed-methods approach, utilizing both surveys and interviews, to examine the impact of real-time volunteer apps on social justice from the perspectives of both visually impaired people (VIP) and non-impaired people (NIP). Our results reveal unintended adverse effects associated with the use of real-time volunteer apps. Despite enhancing perceived social connection, these apps paradoxically increase VIP's prejudice vulnerability, which is potentially attributed to the social contrast effect. Meanwhile, app usage increases NIP's stereotyping and reduces their social acceptance of VIP groups, as these apps fail to create equal status contact between NIP and VIP. This research illuminates the complex dynamics of how information technology (IT) affects social justice for VIP and highlights the overlooked downside of IT. It advances our understanding of intergroup contact theory by providing empirical evidence on contact effects when equal status conditions are lacking and serves as a reminder to app designers and developers of the crucial role of social influence in app design, particularly in the development of apps intended for minority groups.
