To study the corrosion resistance of the novel alloy Al‐12.6La (wt%) manufactured using directional solidification.

Samples fabricated using the Bridgman growth technique at three different withdrawal velocities were subjected to total immersion tests in distilled water and in 3.5 per cent NaCl solution and to DC polarisation tests in distilled water. XPS analyses conducted on samples after polarisation indicated the presence of an La compound in the non passive corrosion products film formed.

Anodic polarisation induced dissolution of the alloy with the formation of a non passive corrosion product film. During potentiodynamic polarisation, a sudden current increment occurred at a potential value that was more positive for samples solidified at higher rates. The corrosion resistance of this Al‐12.6%La alloy decreased as the solidification rate increased.

The results presented in this work are an insight to the understanding of the corrosion resistance and electrochemical behaviour of this alloy for future engineering applications and development.

This paper aims to focus on the evolution of nonprofit cultural institutions in Mexico and their relationship with Spain, regarding the four traditional elements of a marketing mix. Specifically, this paper examines marketing advancements in the digital environment, placing emphasis on the virtual exhibition Códices de México: Memorias y Saberes, as well as the marketing activities related to prehispanic and novohispanic codices between 2010 and 2022.

The first part of the present study provides a chronological framework based on the four components of a marketing mix, illustrating the transition of Mexican and Spanish public cultural institutions from their foundations to current times. It particularly provides insight into their recent accomplishments in the digital environment, underscoring potential networking areas. The second part offers an in-depth examination of the exhibition Códices de México: Memorias y Saberes (INAH 2015) and a review of digital sources from Mexican government entities to investigate marketing activities related to prehispanic and novohispanic codices.

Due to the historical approach used to document the transition of nonprofit cultural institutions in Mexico and Spain to the digital era, this article sheds lights on co-joint efforts in the digital marketing domain around prehispanic and novohispanic codices. Additionally, it illustrates the activities used by Mexican cultural institutions during the past two decades to disseminate knowledge on codices.

Regarding the methodological aspects of using historical resources through digital archives, this study solely comprised marketing activities reported in the records available on the official portal of cultural institutions.

This study argues for the utility of the four components rooted in a traditional marketing mix as a tool to illustrate the evolution of marketing practices within the cultural heritage domain. It also highlights the role played by cultural institutions in Mexico and Spain in the digital environment to strategically network around cultural heritage. Additionally, it sheds light on the implementation of methods for presenting Mexican codices grounded in virtual terrain.

Answering two questions: What do people believe is the gender makeup of different occupations? If there is a systematic difference between the actual and perceived gender composition what factors predict or mediate this difference?

We integrate three occupation-level datasets: ratings of perceived gender composition and cultural sentiments (EPA ratings) for every 2010 Census occupation collected for this study, occupational characteristics from O*NET, and demographic characteristics from the 2015 to 2019 Current Population Survey. Regression models examine the association between sentiments and objective occupational traits on the perceived gender composition net of the actual gender composition.

While respondents underestimate extreme values, perceptions largely reflect actual composition. Gendered sentiments had a significant independent effect on gender composition perceptions. Examining the relationship between objective occupational features, sentiments, and perceptions allows scholars to better understand the links between structural conditions, gendered beliefs, and social action. If individuals underestimate the extent of gender segregation and view some occupations as more diverse than they are, they may be more willing to consider occupations inconsistent with their gender identity. On the other hand, if they misperceive gender composition because of cultural sentiments, they may choose an occupational course somewhat different from their intentions.

Research on gender composition typically employs either a macro approach based on governmental statistics or a micro approach that examines a limited number of occupations. This is the first study to conduct a complete census of every Census occupation for perceived gender composition and cultural sentiments.

The purpose of this paper is to study how job flexibility influences job satisfaction among Mexican professionals, and focus on the role of key socio-cultural moderators relevant to Mexican society.

The paper explore how this relationship may be more important for women, employees with dependents such as children and elder parents and younger generations of professionals (e.g. Millennials).

The authors find that job flexibility is positively related to job satisfaction. This relationship is stronger for employees without dependents, as well as for younger generations of professionals (e.g. Millennials). Surprisingly, the relationship between job flexibility and job satisfaction does not differ by gender. The findings explain why job flexibility is more conductive to job satisfaction for employees without dependents, who tend to belong to younger generations.

Overall, the findings present important implications for managing job flexibility in Mexico and other Latin American countries, particularly for younger professionals.

The purpose of this study is to investigate whether athletic identity contributes to discretionary effort among employees. Athletic identities have long been associated with “giving 110 percent” by exerting high levels of discretionary effort. In response, a growing number of organizations have enacted recruiting programs to specifically seek out prospective employees among individuals who are likely to exhibit strong athletic identities. However, the belief that strong athletic identities will spill over to greater discretionary effort at work has not received systematic examination.

Drawing on a field study of over 1,000 working professionals across various countries and industries, the current study explored whether athletic identity was predictive of discretionary work effort through behavioral self-control and locus of control. Bootstrapping procedures that are robust to any normality distribution violations were implemented.

Results suggest that athletic identity indirectly influences employee discretionary work effort through higher behavioral self-control and a more internal locus of control. These effects were found even when controlling for actual weekly metabolic energy expenditure, age, gender and education.

This study supports the relationship between athletic identity and discretionary effort in the workplace, mediated by greater self-regulation and internal locus of control when compared to those with weaker athletic identities. Importantly, these results were found even while controlling for actual metabolic activity, suggesting that identifying as an athlete is associated with greater internal locus of control and behavioral regulation independent of actual current physical activity. The findings suggest support for human resource practices that prioritize recruiting individuals with strong athletic identities.

It is imperative to achieve sustainable growth in farmers' earnings to sustain poverty alleviation efforts and achieve rural revitalization goals. The authors investigated the nature of the non-linear relationship between farmers' e-commerce participation and income growth, analyzed the rationale behind this correlation and examined the moderating effect of digital finance on this relationship.

The authors conducted an empirical investigation using rural household data from the China Household Finance Survey and the regional digital finance index compiled by Peking University. The authors employed a fixed-effect model and a moderating effect model to identify the non-linear influences of e-commerce participation on farmers' income and to analyze the positive synergies of digital finance. The authors used identification and estimation techniques to mitigate the endogeneity problem, specifically employing heteroscedasticity-based instruments.

There is an inverted U-shaped relationship between e-commerce participation and farmers' income. Digital finance reduces the declining trend in the marginal effects of e-commerce and increases marginal values. Furthermore, the synergistic effect can promote the quality and efficiency of business activities by easing credit constraints, reducing risk aversion and stimulating innovative activities, which in turn can lead to sustained revenue growth.

Few studies have focused on the non-linear relationship between e-commerce and farmers' income. This implies that achieving sustained income growth using e-commerce alone is difficult. The synergy between e-commerce and digital finance is a feasible path for achieving this goal.

Many studies have developed the corporate sustainability topic. The United Nations has implemented the 2030 Agenda and has brought “quality education” and “industry, innovation, and infrastructure” as two of the 17 Sustainable Development Goals. The educational processes in higher education can be focused on adding brand value and social value, and they can be promoting the social inclusion. In this sense, the purpose of this study is to answer some questions related to the corporate sustainability practices under the 2030 Agenda lenses in the Latin American higher educational scenario. After the literature review analysis, a conceptual framework was developed.

This exploratory research study proposes an educational conceptual framework, improving the corporate sustainability under the 2030 Agenda lenses. A literature review was developed, involving the seven variables: “Latin America,” “higher education,” corporate social responsibility,” “personal social responsibility,” “corporate sustainability,” “governance” and “sustainability.” A matrix was developed with 25 variable combinations, connecting the seven variables. Three questions have been proposed and answered: “How much research has been developed in the Latin American higher education?” “How can the corporate social sustainability be applied in higher education?” and “Which perspectives can be considered?”

The results of the literature review are presented through the number of papers found with the analysis of the year of publication and the conceptual background. A total of 524 papers were found. Of these studies, 49 addressed the Latin American panorama, 33 had a general approach and 16 promoted interactions between Latin American and European countries, as well as between regions and continents. Six topics emerged from the literature analysis: digital inclusion, internationalization, innovation, research, servitization and social inclusion. These topics are connected in the “discussion” section, and the educational conceptual framework shows the corporative perspectives on sustainability in higher education.

This research study presents “A conceptual framework for the corporate sustainability higher education in Latin America” and it brings some discussion topics: digital inclusion, internationalization, innovation, research, servitization and social inclusion. These topics were identified through the literature analysis, and they were applied in the conceptual framework to improve the quality of education. The implications of this study are connected with the conceptual framework to promote the discussion topics. The implications involved the public and private governance spheres, third sector, as well as the professors, students and other stakeholders of higher educational institutions. These implications can represent an agent of positive change in the Latin American scenario.

Employees in the private, public, and third sectors have experienced an increase in stress over the years. Amongst the sectors, people working in hospitals and other healthcare facilities were put under severe stress during the COVID-19 pandemic. Indeed, the World Health Organisation has clearly stated that defending people's mental health at this particular time of restless pandemic growth is an absolute necessity. The purpose of this article is to assess the perceived work-related stress (WRS) of healthcare workers (HCWs) as a result of the spread of COVID-19, as well as how a leadership role can help to reduce WRS.

Based on a multiple case study approach applied to two Italian health-care facilities, the questionnaire results were subjected to a regression analysis.

The results show an association in HCWs between the perception of supportive leadership and the perception of negative psychosocial risks whose exposure can lead to manifestation of WRS during COVID-19 pandemic.

The study addresses the role that the perception of supportive leadership can play in reducing exposure to occupational psychosocial risks in a sample of healthcare professionals.

This paper aims to examine the design and control of a symmetric multilevel inverter (MLI) using grey wolf optimization and differential evolution algorithms.

The optimal modulation index along with the switching angles are calculated for an 11 level inverter. Harmonics are used to estimate the quality of output voltage and measuring the improvement of the power quality.

The simulation is carried out in MATLAB/Simulink for 11 levels of symmetric MLI and compared with the conventional inverter design. A solar photovoltaic array-based experimental setup is considered to provide the input for symmetric MLI. Field Programmable Gate Array (FPGA) based controller is used to provide the switching pulses for the inverter switches.

Attempted to develop a system with different optimization techniques.
