Polymer laser powder bed fusion (PBF-LB/P) is an additive manufacturing technology that is sustainable due to the possibility of recycling the powder multiple times and allowing the fabrication of gears without the aid of support structures and subsequent assembly. However, there are constraints in the process that negatively affect its adoption compared to other additive technologies such as material extrusion to produce gears. This study aims to demonstrate that it is possible to overcome the problems due to the physics of the process to produce accurate mechanism.

Technological aspects such as orientation, wheel-shaft thicknesses and degree of powder recycling were examined. Furthermore, the evolving tooth profile was considered as a design parameter to provide a manufacturability map of gear-based mechanisms.

Results show that there are some differences in the functioning of the gear depending on the type of powder used, 100% virgin or 50% virgin and 50% recycled for five cycles. The application of a groove on a gear produced with 100% virgin powder allows the mechanism to be easily unlocked regardless of the orientation and wheel-shaft thicknesses. The application of a specific evolutionary profile independent of the diameter of the reference circle on vertically oriented gears guarantees rotation continuity while preserving the functionality of the assembled mechanism.

In the literature, there are various studies on material aging and reuse in the PBF-LB/P process, mainly focused on the powder deterioration mechanism, powder fluidity, microstructure and mechanical properties of the parts and process parameters. This study, instead, was focused on the functioning of gears, which represent one of the applications in which this technology can have great success, by analyzing the two main effects that can compromise it: recycled powder and vertical orientation during construction.

The investigation goal is the analysis of the relation between healthcare expenditures and other resources, and COVID-19 fatality rates among European countries to design effective health policies for crisis management.

Research methodology is based on descriptive statistics and various parametric methods, also including a linear model of regression to analyze basic relationships of variables under study.

Results show that a lower COVID-19 fatality rate is associated with higher levels of health expenditure (% GDP), of healthcare expenditure per capita, health expenditure in preventive care (% GDP), hospitals per million inhabitants, physicians, nurses, hospital beds and curative acute care beds per 1,000 inhabitants. Regression analysis shows that a 1% increase in healthcare expenditures per capita of countries, it reduces the level of COVID-19 fatality rate by 0.74%. In fact, many countries in Eastern Europe with low healthcare expenditures per capita in 2019 (e.g., Bulgaria, Romania, Hungary, Poland, Latvia, Slovakia, Lithuania, etc.), they have experienced high COVID-19 fatality rates. Instead, a lot of countries in Western Europe, with high healthcare expenditures per capita, such as Germany, Denmark, Austria, and the Netherlands, they had resilient health systems to face pandemic crisis and lower COVID-19 fatality rates.

These findings suggest strategies of systematic and continuous investments in healthcare, medical technologies, and ICT infrastructures to support effective health policy of crisis management in countries to face future pandemic crisis and other emergencies in society.

The explanation of critical role of high health expenditure (% GDP) and healthcare expenditure per capita to support robust health systems that bolster the resilience in nations to face health emergencies and worldwide crises.

This study aims to investigate how the presence of female executives on the board affects a company’s capital structure decisions. The critical mass of female executives on the board was also considered to observe their impact on capital structure.

Samples were taken from nonfinancial sector companies listed on the Indonesia Stock Exchange between 2012 and 2021 (3,707 firm-year observations). Capital structure was measured using four approaches, namely, debt-to-total asset ratio (DAR), debt-to-equity ratio (DER), short-term debt-to-total assets (STD) and long-term debt-to-total assets (LTD). The data were analyzed using panel data regression analysis, including a fixed effects model with clustered standard errors.

The presence of female executives on the board is significantly negatively related to capital structure as measured by DER and STD. The critical mass of women provided no evidence of a relationship with a firm’s capital structure. Robustness checks were performed, and the results were consistent with those in the main analysis.

Female executives can be appointed to management boards when determining a strategy to achieve the capital structure desired by a company.

This study increases the diversity of research in corporate governance by synthesizing various indicators from female executives into a single study to determine their relationships with companies’ capital structures. In addition, this study stands out by incorporating four distinct indicators for assessing capital structure and diverging from the norm observed in many other studies, many of which rely on just two indicators: DAR and DER. Moreover, it strongly emphasizes the unique economic, legal, social and cultural landscapes of developing countries like Indonesia in comparison to their developed counterparts, particularly Western nations.

This study aims to examine the effect of the interplay between national culture and supervisor gender on supervisors’ supportive behaviours towards employees in Europe.

Based on Hofstede’s cultural scores for 34 European countries, two clusters of countries were identified, reflecting two cultural configurations: favouring versus not favouring gender equality (GE). For hypotheses testing, the authors used a sample of 21,335 native employees, obtained from the European Working Conditions Survey.

Women in supervisory positions, compared to men, provided more support to subordinates in terms of respect, recognition, encouraging development and providing feedback. In countries with cultures favouring progress towards GE (small power distance, weak uncertainty avoidance, individualism and indulgence), only respect and recognition were more prevalent. In countries with opposing cultural configurations, other supportive behaviours stood out: coordinating work, providing feedback and helping with work. Furthermore, the impact of supervisor gender on supportive behaviours was influenced by national culture. Gender differences were larger in countries with a culture favouring progress towards GE compared to countries not favouring such progress.

The authors present a pioneering study that delves into national values as they relate to progress towards GE to understand the differences between male and female supervisors in the display of six supportive behaviours towards their subordinates. Their cultural approach nuances some of the predictions of social role theory.

The purpose of this study is to examine the impact of country-level governance on sustainability performance, taking into account the effect of sustainable development goals (SDGs) and board characteristics.

This study uses panel data analysis using fixed effect models to investigate the influence of country-level governance on sustainability performance while considering the effect of SDGs and board characteristics. The sample comprises 8,273 firms across 41 countries during the period spanning from 2016 to 2021. The sample is divided into two categories based on the score of SDGs.

The findings of this study show that countries with high SDGs score have better overall country-level governance and board attributes which have a statistically significant positive impact on sustainability performance. However, for those countries with low SDGs, political stability shows a statistically insignificant and negative impact on sustainability performance, while government effectiveness indicates a statistically insignificant positive impact on sustainability performance.

This study contributes to the literature by providing empirical evidence on the relationship between country-level governance, SDGs, board characteristics and sustainability performance. The study also highlights the importance of considering the effect of SDGs on the relationship between country-level governance and sustainability performance. The findings of this study could be useful for policymakers and firms in improving their sustainability performance and contributing to sustainable development.

This paper aims to challenge the notion that “having-less” – limiting consumption of scarce resources to a select few – represents a social responsibility route toward guilt reduction. It rather argues that “saving-more” – the purposeful pursuit of conscious and collaborative consumption – captures consumers’ true representations of responsible luxury which in turn reduces anticipated guilt.

Six experiments using different operationalizations of saving-more (vs. having-less) and a mix of fictitious and real luxury brands were conducted on real luxury buyers.

The findings demonstrate that saving-more (vs. having-less) leads to a stronger purchase intention; an effect explained by a higher responsible luxury perception and lower anticipated guilt associated with saving-more (vs. having-less). Furthermore, the ability of saving-more (vs. having-less) in building responsible luxury perception and reducing anticipated guilt is stronger (vs. weaker) when luxury is distributed based on deservingness (vs. entitlement).

This research proposes a novel distinction between two responsible luxury approaches: promoting limited consumption for business goals, that is, having-less and promoting conscious consumption for societal goals, that is, saving-more.

Brand managers can enhance responsible luxury perception and reduce consumer guilt through corporate communication, product communication and collaborative product accessibility modes. Managers must also convince consumers that their access to luxury is based on real achievements.

This study empirically invalidates the notion that merely invoking scarcity and rarity tactics is an expression of social responsibility. It integrates social responsibility and fairness accounts of guilt into a coherent theory of guilt over luxury consumption.

Despite some recent progress, gender inequality remains a persistent problem in science, technology, engineering, mathematics and medicine (STEMM) organisations. This article seeks to better understand resistance to gender equality (GE) in this context with the aim of shedding light on the workplace-based impediments to equality and unlocking remediation opportunities.

The article draws on in-depth interviews with 20 STEMM leaders to examine how they talk about the problem of gender inequality in the organisations they lead. Because resistance is rarely expressed directly, we adopt an in-depth, granular approach to examining what we call STEMM leaders’ “resistance talk” by decoding expressions of GE resistance that may appear, ostensibly, as something else.

We found various ideas, arguments and other discursive practices which function to legitimate or justify the status quo. These are both described by leaders in relation to what they are dealing with in their own organisations and expressed themselves. While similar “legitimating discourses” operate in other gender-segregated workplaces, our findings show how they manifest specifically in STEMM contexts.

Our results provide much-needed granular level evidence of the discursive tactics deployed to legitimate the status quo and obstruct progress toward GE in STEMM. This extends understanding of barriers to GE in STEMM and, importantly, highlights where attention might be directed to both counter resistance and harness potentially changing attitudes to expedite the necessary change required for GE in STEMM.

Electric cars have very little market share in developing countries despite their environmental benefits. Thus, governments have started promoting electric cars by providing financial incentives to consumers. The current article aims to examine the direct and indirect effects of government financial incentives on consumer electric car adoption in India.

The study followed a quantitative research method that employed a self-administered survey questionnaire. Structural Equation Modelling and Multi-Group Analysis were followed for data analysis.

The study revealed that financial incentives have an indirect effect on electric car adoption intention rather than a direct effect. In addition, financial incentives were found to have a direct effect on attitude and Perceived Behavioural Control (PBC). Attitude and PBC positively influenced consumer adoption intention.

The insights and implications from the present study would help policymakers and marketers to formulate better incentive policies and market strategies to increase consumer acceptance of electric cars in developing countries.

The study contributes to the literature by analysing the underlying mechanism that links government financial incentives to electric car adoption intention. This study also explored the direct effect of financial incentives on attitude and PBC, which are less investigated in electric vehicle literature. In addition, the present article also assessed the moderating role of age in electric car adoption, which has mixed evidence in the literature, and such studies are scarce in the Indian context.

This paper aims to investigate the role of corporate governance on the bank profitability of Indian banks vis-à-vis South Asian Association for Regional Cooperation (SAARC) nations.

For the Corporate Governance Index, the authors examined board accountability, transparency and disclosure and audit committee, while Tobin’s Q, return on equity and return on assets are used to measure the bank’s profitability. The study used a two-stage analysis based on balanced panel data for robust findings. Sample of this study consists of 60 commercial banks from India and 60 banks from SAARC nations for the period of 2009–2021. This study used panel regression and a generalized method of moment approach using the CAMELS framework on banking industry-specific variables to determine their respective impacts.

The findings of this study suggest that board accountability is positive and significantly affects the profitability of banks as indicated by return on assets, return on equity and Tobin’s Q. In contrast, the audit committee has a positive and insignificant impact on return on assets, return on equity and Tobin’s Q, while transparency and disclosure have a negative and significant impact on these metrics. Furthermore, the country dummy result shows a significant positive impact on all the bank performance parameters, implying that Indian banks have the highest degree of convergence with corporate governance as compared to other SAARC nations.

This study provides insight to the regulators, policymakers and financial institutions to evaluate the role of corporate governance in emerging economies. However, the findings of the study should be interpreted with caution, as the results are sensitive to the disparity between India and other SAARC nations' government policies, climatic circumstances and cultural or religious traditions.

To the best of the authors’ knowledge, this is the first attempt to gauge the performance of Indian banks vis-à-vis SAARC nations using the CAMELS framework approach. Further, findings of this study suggest some novel evidence tying corporate governance quality with the profitability of banks among SAARC nations.

Modular capacity units enable rapid reconfiguration, providing tactical flexibility to efficiently meet customer demand during disruptions and ensuring sustainability. Moreover, the Physical Internet (PI) enhances the potential of modular capacity in addressing efficiency, sustainability, and resilience challenges. To evaluate the sustainability and resilience advantages of the PI-enabled reconfigurable modular system (PI-M system), this paper studies a PI-enabled sustainable and resilient production-routing problem with modular capacity.

We develop a multi-objective optimization model to assess the sustainability and resilience benefits of combining PI and modular capacity in a chemical industry case study. A hybrid solution approach, combining the augmented e-constraint method, construction heuristic, and hybrid adaptive large neighborhood search, is developed.

The experimental results reveal that the proposed solution approach is capable of obtaining better solutions than the Gurobi and the existing heuristic in a shorter running time. Moreover, compared with the traditional system, the PI only and traditional with modular capacity systems, PI-M system has significant advantages in both sustainability and resilience.

To the best of our knowledge, this study is the first to integrate the PI and modular capacity and investigate sustainability and resilience in the production-routing problem.
