Women are underrepresented in STEM (science, technology, engineering, and mathematics) careers, and this poses new challenges at the dawn of the era of digital transformation. The goal of the present study is to demonstrate how female role models influence girls’ preferences for STEM studies. This paper evaluates a role-model intervention in which female volunteers working in STEM go into schools to talk to girls about their careers. The study was conducted with 304 girls, from 12 years old (sixth primary grade) to 16 years old (fourth secondary grade), both before and after the role-model sessions. An adaptation of the expectancy–value theory of achievement motivation is used to test the extent to which this role-model intervention improves girls’ beliefs that they can be successful in STEM fields and increases their likelihood of choosing a STEM career. The results of multigroup structural equation modeling analysis show that on average, the role-model intervention has a positive and significant effect on mathematics enjoyment, importance attached to math, expectations of success in math, and girls’ aspirations in STEM, and a negative effect on gender stereotypes. Additionally, the female role-model sessions significantly increase the positive impact of expectations of success on STEM choices. Finally, the moderation role of the counterstereotypical content of the role-model sessions is tested. The results show that the higher the counterstereotypical character of the sessions, the higher the relationship between expectations of success in math and the choice of STEM. These results are discussed regarding their implications for long-term STEM engagement.

This study analyses the impact of political and regulatory pressures to increase the influence of women within the European board of directors’ network. To accomplish this, we used a longitudinal approach, tracking two centrality measures of a European directors’ network from 1999 to 2014. The network comprised publicly listed firms in 37 European countries, resulting in an extensive sample of 71,300 directors, of which around 10% were women. Governments promoting gender diversity in leadership positions have focused on two solutions: a slow track using voluntary approaches versus a fast track pushing for binding legislation. The panel data analysis shows how voluntary approaches to promote gender diversity, as implemented through corporate governance codes, have a positive and significant relationship with the ‘closeness’ of women to other directors in the network (i.e. their access to information). In contrast, binding legislation, such as gender quotas, increases women's role as unique ‘bridges’ between sub-networks – a result that serves to heighten their ‘betweenness’ centrality (i.e. their control over information).

The mechanisms driving SARS-CoV-2 susceptibility remain poorly understood, especially the factors determining why unvaccinated individuals remain uninfected despite high-risk exposures. To understand lipid and metabolite profiles related with COVID-19 susceptibility and disease progression. We collected samples from an exceptional group of unvaccinated healthcare workers heavily exposed to SARS-CoV-2 but not infected (‘non-susceptible’) and subjects who became infected during the follow-up (‘susceptible’), including non-hospitalized and hospitalized patients with different disease severity providing samples at early disease stages. Then, we analyzed their plasma metabolomic profiles using mass spectrometry coupled with liquid and gas chromatography. We show specific lipids profiles and metabolites that could explain SARS-CoV-2 susceptibility and COVID-19 severity. More importantly, non-susceptible individuals show a unique lipidomic pattern characterized by the upregulation of most lipids, especially ceramides and sphingomyelin, which could be interpreted as markers of low susceptibility to SARS-CoV-2 infection. This study strengthens the findings of other researchers about the importance of studying lipid profiles as relevant markers of SARS-CoV-2 pathogenesis.

Research question/issue This study examines the influence of group behavior on board gender diversity and identifies obstacles to its diffusion. It investigates whether boards are influenced by group behavior in determining their gender composition and explores barriers that impede the diffusion process. Research findings/insights Analyzing a network of over 18,000 US-listed boards observed over 20 years, we find a pattern of mimetic behavior, whereby boards imitate the proportion of women on boards (WoB) among their directly tied boards. We also identify resistant firms with low representation of women on their boards. Our findings suggest that, among those boards, there are heavily male-dominated boards resisting the appointment of women, even when surrounded by women directors among their tied boards. The diffusion of board gender diversity is slowed down by these resistant boards, hindering the overall progress in increasing gender diversity within the board network. Theoretical/academic implications This research contributes insights into group behavior and resistance in board gender diversity. Adopting a network theory lens, our study sheds light on interactions between firms and their connected companies in terms of imitation practices. Drawing on social identity theory, we highlight the significance of the resistance to increasing women's representation exhibited by some boards. Practitioner/policy implications Resistant boards, despite group pressure, slow down the diffusion of board gender diversity within the network, leading to overall stagnation. Understanding the sources of resistance allows an exploration of alternative measures to promote diversity without rigid mandates.

Telerehabilitation is an option that should be adapted as soon as possible to face the crisis caused by coronavirus disease 2019. An umbrella and mapping review with meta–meta-analysis (MMA) of the available scientific evidence was performed to determine whether telerehabilitation could be an effective alternative to conventional rehabilitation in physical therapist practice. A systematic review of reviews and a synthesis of the findings of all systematic evidence published to date with a visual map and a meta–meta-analysis (MMA) were performed. A systematic search was realized in Cochrane Database of Systematic Reviews, MEDLINE (PubMed), and Google Scholar. Two independent reviewers performed a data analysis and assessed the quality of the included reviews, assessing the risk of bias using ROBIS. Twenty-nine articles that met the inclusion criteria were selected and divided according to the type of patient targeted for rehabilitation (patients with cardiorespiratory,musculoskeletal, and neurological conditions). The MMA regarding physical function between telerehabilitation and usual care rehabilitation did not reveal a statistically significant difference for patientswith cardiorespiratory andmusculoskeletal conditions. For patientswith neurological conditions, theMMArevealed a statistically significant but negligible effect size in 6 reviews in favor of telerehabilitation (standardized mean difference = 0.18; 95% CI = 0.03–0.34). The results of the present review showed that telerehabilitation offers positive clinical results, even comparable to conventional face-to-face rehabilitation approaches. Impact. The advantages of lower cost and less interference by the rehabilitation processes in patients’ daily life could justify implementing telerehabilitation in clinical settings in the coronavirus disease 2019 era.

Pulmonary rehabilitation is one of the main interventions to reduce the use of health resources, and it promotes a reduction in chronic obstructive pulmonary disease (COPD) costs. mHealth systems in COPD aim to improve adherence to maintenance programs after pulmonary rehabilitation by promoting the change in attitude and behavior necessary for patient involvement in the management of the disease. This study aimed to assess the effects of an integrated care plan based on an mHealth web-based platform (HappyAir) on adherence to a 1-year maintenance program applied after pulmonary rehabilitation in COPD patients. COPD patients from three hospitals were randomized to a control group or an intervention group (HappyAir group). Patients from both groups received an 8-week program of pulmonary rehabilitation and educational sessions about their illness. After completion of the process, only the HappyAir group completed an integrated care plan for 10 months, supervised by an mHealth system and therapeutic educator. The control group only underwent the scheduled check-ups. Adherence to the program was rated using a respiratory physiotherapy adherence self-report (CAP FISIO) questionnaire. Other variables analyzed were adherence to physical activity (Morisky-Green Test), quality of life (Chronic Obstructive Pulmonary Disease Assessment Test, St. George’s Respiratory Questionnaire, and EuroQOL-5D), exercise capacity (6-Minute Walk Test), and lung function. In total, 44 patients were recruited and randomized in the control group (n=24) and HappyAir group (n=20). Eight patients dropped out for various reasons. The CAP FISIO questionnaire results showed an improvement in adherence during follow-up period for the HappyAir group, which was statistically different compared with the control group at 12 months (56.1 [SD 4.0] vs 44.0 [SD 13.6]; P=.004) after pulmonary rehabilitation. mHealth systems designed for COPD patients improve adherence to maintenance programs as long as they are accompanied by disease awareness and patient involvement in management.

In 1962, Spain implemented significant banking law changes to boost competition. This study investigates their impact on provincial banking concentration from 1964 to 1975, utilising novel provincial-level private bank balance sheet data and including savings banks. Results show a substantial decline in concentration across most provinces. Panel data models identify the determinants of banking concentration: larger populations and higher gross domestic product per capita correlate with lower concentration, while agrarian-focused provinces exhibit higher concentration. The provincial financial sector's structure also matters, with a higher number of branches and headquarters per capita associated with reduced banking concentration. These findings refine existing literature and provide new insights into the intricate relationship between banking concentration and regional economies in Spain.

Women are still underrepresented in STEM careers (Science, Technology, Engineering, and Mathematics). One of the possible drivers behind this gender gap in the labour market is the female dropout from STEM education. The causes of the gender differences in the persistence of pursuing STEM studies have been explained by multiple factors related to interest and resolution in this type of career. The goal of the present research is to study the Engineering persistence gender gap in higher education by exploring the main factors underlying the leakage in the pipeline of Engineering fields. Our study reports the results of 34 qualitative in-depth interviews where internal barriers, stereotypes and external obstacles are assessed by women who have left their university degrees, compared with men who have withdrawn and women who have persisted. Results from the content analysis suggest that the undermining of persistence in Engineering fields is related to factors such as the chilly and hostile environment in classes or the workload from an excessively demanding curriculum. Other factors affecting women’s withdrawal are the lack of role models and the perceived incongruity between the female gender role and STEM roles in society, leading to a weakening of female students’ self-efficacy and eroding their sense of belongingness, even making them consider dropping out of their Engineering degree. These findings provide information for the design of future STEM interventions aimed to enhance women’s persistence in STEM university studies.

A part of the financial literature has attempted to explain idiosyncratic asset shocks through investor behavior in response to company news and events. As a result, there has been an increase in the development of different investor sentiment measurements. This paper analyses whether the Bloomberg investor sentiment index has a causal relationship with the abnormal returns andvolume shocks of major European Union (EU) financial companies through a sample of 85 financial institutions over 4 years (2014–2018) on a daily basis. The i.i.d. shocks are obtained from a factorial asset pricing model and ARMA-GARCH-type process; then we checked whether there is both individual and joint causality between the standardized residuals. The results show that the explanatory capacity of the shocks of the firm Bloomberg sentiment index is low, although there is empirical evidence that the effects correspond more to the situation of the financial subsector (banks, real estate, financial services and insurance) than to the company itself, with which we conclude that the sentiment index analyzed reflects a sectorial effect more than individual one.

This study explores the realm of authentic leadership theory to examine how female teenagers can enhance relational authenticity and develop authentic leadership skills through a specialized program. Employing multigroup Structural Equation Modeling (SEM), we assess the impact of this leadership intervention on female teenagers, comparing pre- and postintervention results. Additionally, we contrasted the outcomes of program participants with those of same-aged, nonparticipating students from similar backgrounds. The analysis revealed a significant increase in the scores for the four constructs of authentic leadership among the program’s participants. Notably, their academic grades also improved post-intervention. Focusing on high school females aged 16 years and above, the study addresses a critical age for developing selfperception of competence and confidence. The persistent underrepresentation of females in leadership roles underscores the necessity for early interventions like this one. These findings contribute to a deeper understanding of how a leadership program can positively influence the development of authentic leadership skills among participants, while also observing enhancements in academic achievement following this particular intervention.
