Abstract

Purpose

This paper aims to present an analytical approach for the determination of helical gear tooth geometry and introduces the necessary parameters. Tooth geometry including tooth chamfer, involute curve, root fillet, helix as well as tooth microgeometry can be obtained using the presented approach.

Design/methodology/approach

The presented analytical approach involves deriving the equivalent equations at the transverse plane rather than the normal plane. Moreover, numerical evaluation of microgeometry modifications is presented for tooth profile, tooth lead and flank twist.

Findings

An analytical approach is presented and equations are derived and explained in detail for helical gear tooth geometry calculation, including tooth microgeometry. Method 1, which was presented by Lopez and Wheway (1986) for obtaining the root fillet, is examined and it is proven that it does not work accurately for helical gears, but rather it works perfectly in the case of spur gears. Changing the normal plane parameters in Method 1 to the transverse plane ones does not give correct results. Two alternative methods, namely, Methods 2 and 3, are developed in the current research for the calculation of the tooth root fillet of helical gears. The presented methods and also the numerical evaluation presented for microgeometry modification are examined against the geometry obtained from Windows LDP software. The results show very good agreement, and it is feasible to apply the approach using the presented equations.

Originality/value

In the gear design process, it is important to model the correct gear tooth geometry and deliver all related dimensions and calculations accurately. However, the determination of helical gear tooth geometry has not been presented adequately by equations to facilitate gear modelling. The detailed helical gear tooth root has been enveloped using software tools that can simulate the cutter motion. Deriving those equations, presented in this article, provides gear design engineers and researchers with the possibility to model helical gears and perform design calculations in a structured, applicable and accurate method.

Abstract

Purpose

This paper aims to provide insights into the potential of digital technologies-based innovations for more inclusive healthcare by alleviating the affordability, accessibility and availability barriers to utilization of healthcare services. Also, it aims to provide insights into the potential of digital technologies-based innovations for more inclusive services, broadly.

Design/methodology/approach

A conceptual framework is inductively developed by analyzing real-world examples of digital technologies-based innovations for more inclusive healthcare through the lenses of economics of information in digital form and certain characteristics of services.

Findings

Concurrent implementation of digital technologies-based healthcare innovations with innovations and/or modifications in service processes can enable greater inclusivity by alleviating the affordability, accessibility and availability barriers to utilization of healthcare services.

Research limitations/implications

Issues relating to inequities in healthcare, as a social problem, are the focus of research at multiple levels (e.g. global, national, regional and local) in several academic disciplines. In relation to the scope of the problems and challenges pertaining to providing quality healthcare to the unserved and underserved segments of society, worldwide, the contribution of the proposed framework to practice is modest. However, by highlighting the promise and potential of digital technologies-based innovations as solutions for alleviating barriers to affordability, accessibility and availability of healthcare services during various stages (prevention, detection, diagnosis, treatment and post-treatment follow-up) with illustrative vignettes and developing a framework, the article offers insights for future research. For instance, in reference to mission-driven social enterprises that operate in the product-market space for inclusive innovations under resource constraints, a resourcefulness-based view of the social enterprise constitutes a potential avenue for theory development and research.

Practical implications

Given the conceptual nature of the article, the implications for practice are limited to cognitive implications. Action implications (instrumental implications or implications for practice) are outside of the scope of the article.

Social implications

Innovations that are economically viable, environmentally sustainable and socially impactful is one of the important issues of our times.

Originality/value

The proposed framework provides insights into the potential of digital technologies-based innovations for more inclusive healthcare by alleviating the affordability, accessibility and availability barriers in the context of emerging and less developed country markets and base of the pyramid segments of society in these markets.

Abstract

Purpose

The purpose of this study is to document the process of transformative learning during students’ internships.

Design/methodology/approach

A qualitative study was conducted with 13 interviewed students to gain deeper insights into their learning experiences during their internships. Their weekly reflections from their 6 month’s internship experience were also coded for common themes.

Findings

The study found numerous trigger events ranging from task-related challenges to interpersonal challenges to environmental challenges led to mindset shifts in students during their internships. The mindset shifts are enabled by students engaging in the trigger events through asking questions, seeking information and reflecting. Other enablers of these mindset shifts are workplace psychological safety, social support and individual learning orientation. The conclusion drawn is that trigger events and enabling resources such as external support are central to healthy mindset shifts and learning.

Practical implications

This paper provides important guidance for supporting transformative learning during student internships.

Originality/value

This paper provides important guidance for supporting transformative learning during student internships.

Abstract

Purpose

Pregnant employees experience considerable interpersonal discrimination. This study explores the range of possible reactions of observers to pregnancy self-disclosure, interpersonal discrimination and various allyship interventions, and the attentional processes that lead to those reactions. Consequently, it uncovers socio-cognitive processes underlying support for and backlash toward pregnancy in the workplace.

Design/methodology/approach

This study used a thought-listing technique to explore observers’ spontaneous thoughts related to pregnancy. Working adults were randomly assigned to read through one of the six scenarios depicting pregnancy self-disclosure, interpersonal discrimination and male allyship interventions (i.e. stating the organization’s anti-discrimination policy, confronting the transgressor by calling out sexism, pivoting the conversation to highlight the strengths of the pregnant employee and a hybrid intervention combining highlighting strengths and confrontation) after which participants listed the top three thoughts that came to their mind (1,668 responses). Responses were thematically analyzed to explore spontaneous reactions toward the pregnant employee, transgressor and ally in the scenario.

Findings

Surprisingly, across all scenarios, the most sexist thoughts emerged during pregnancy self-disclosure, even in the absence of any transgression. After a transgression occurred, any allyship intervention was better than none in eliciting lesser sexist backlash against the pregnant employee. Stating the organization’s anti-discrimination policy was most beneficial for the pregnant employee in eliciting the least sexist backlash but at the cost of generating unfavorable impressions of the ally. Calling out the transgressor’s bias elicited the most sexist backlash toward the pregnant employee, yet it created favorable impressions of the ally. In contrast, highlighting the strengths of the pregnant employee created the most favorable impression of the ally while eliciting a few sexist thoughts about the pregnant employee. Overall, the hybrid intervention was the most effective at balancing the competing goals of generating support for the pregnant employee, creating favorable impressions of the ally, as well as holding the transgressor accountable.

Originality/value

This study demonstrates that the type of allyship intervention critically redirects the attentional focus of observers to certain aspects of a discrimination episode and relevant schemas which can generate support or backlash toward targets, transgressors and allies, thereby advancing or obstructing equity and inclusion in organizations.

Abstract

By market capitalisation, Bitcoin, which debuted in 2009, is the biggest cryptocurrency globally. A decentralised ledger system called blockchain is used in the creation, distribution, trading, and storage of Bitcoin, with the original goal being to address the shortcomings of fiat currency. This chapter highlights potential dangers and legal concerns when Bitcoin interacts with the actual economy and the traditional financial system. Besides, the details also discuss the platform’s design principles and attributes for a non-technical readership. When assessing its transactional potential, some recognise its potential for speculation, while others are doubtful of its admirable intent. The write-up also explores the potential of the adoption of cryptocurrencies in Southeast Asia due to the vast adoption of Bitcoins in countries such as Vietnam and the Philippines following the establishment of cryptocurrency technology and e-commerce. In addition, rankings of the cryptocurrency and legal stance from each country in Southeast Asia were exhibited as the solid foundation of cryptocurrencies existent for transaction purposes. The rise of central bank digital currencies (CBDC) and the future directions of Bitcoins were also highlighted in this write-up to spur the debate on whether cryptocurrency remains a fad of sensation or is legalised as the medium of exchange in an ever-growing digital world of commerce.

Abstract

After the COVID-19 epidemic, educational paradigms experienced radical changes, especially in the way that architecture was taught. This chapter explores how architecture education evolved because of the current economic crisis, and how COVID-19 has affected instructional approaches. The main goal is to expose emerging educational strategies and their consequences for encouraging flexibility and resilience in architectural instructors and students. The study used a mixed-methods research methodology to gather information from stakeholders, educators, and students of architecture by combining document analysis of academic theses and publications with semi-structured interviews. Data analysis techniques such as thematic coding and pattern recognition revealed distinct categories of influencing factors, such as technological advancements, pedagogical modifications, student engagement and support, curriculum changes, faculty development, resource allocation, assessment and evaluation, as well as global and cultural considerations. The results highlight the varied and dynamic character of the pandemic’s effect. The crisis sparked a faster adoption of digital technologies, bringing forth blended learning and novel pedagogical approaches. As a significant result, resilience helped instructors and students overcome uncertainty by enhancing flexibility and using transdisciplinary methods. It also demonstrates how architectural education has persevered in the face of the COVID-19 epidemic and has the potential to spur larger changes in education. The possibility of sample bias and the crisis’s dynamic character are limits, though. Future research might examine the long-term effects of these emerging methods beyond crisis situations to expand the study’s results and influence the ongoing development of architectural pedagogy in a continuously changing global environment.

Abstract

Purpose

Mainland Tanzania has seen two decades of significant social policy reforms and transformations in its social and economic structures, whilst the country continues to grapple with persisting gender inequalities. This article examines Tanzania's social policy developments from a gender perspective. The authors analyse the level, reach and quality of social policy delivery to working-age women across the areas of health policy, social protection and employment policy during 2000–2021.

Design/methodology/approach

The article draws on qualitative research deploying the scoping review method. The data consist of diverse secondary materials, including academic publications, government policy documents, relevant statistics and other types of “grey” literature.

Findings

Tanzania has made significant advancements in the legal frameworks around welfare provision and has instituted increasingly gender-responsive government policy plans. The health and social protection sectors, in particular, have witnessed the introduction of large-scale measures expanding social policy implementation. However, social policy delivery remains two-tiered, with differences in provisions for women in the formal and informal sectors.

Originality/value

Social policy delivery and implementation have increased and diversified in Sub-Saharan Africa (SSA) during the new millennium, with a growing integration of gender-specific policy objectives. However, limited social policy scholarship has focused on the gendered effects of broader social policy models in SSA. The article remedies the concomitant knowledge gaps by examining various social policies and their impacts on working-age women in Mainland Tanzania. The authors also engage with the theoretical welfare regime literature and present an analytical framework for gender-sensitive assessment of emerging social policy models in the Global South.

Abstract

Purpose

Grounded on regulatory focus theory, this study aims to explore whether the regulatory focus of leadership (promotion versus prevention) influences a firm’s innovation. Moreover, it examines the moderating effect of industry munificence, gender diversity and chief executive officer (CEO) tenure.

Design/methodology/approach

Using random effects and the generalized method of moments (GMM), this relationship was examined using firms listed in the S&P 500 index in the period 2015–2020.

Findings

The evidence suggests that CEOs with a promotion focus significantly impact firms’ innovation, with the relationship being moderated by CEO tenure, gender diversity and industry munificence. However, CEO prevention focus does not determine strategic choices in relation to innovation. The study offers insights into corporate governance and corporate management that address stakeholders’ growing demands to innovate and appoint experienced CEOs with a promotion focus so as to ensure firm growth, particularly under the circumstances of strong market competition.

Originality/value

The study enhances the comprehension of the relevance of CEO regulatory focus and innovation while considering the effect of CEO tenure, gender diversity and industry munificence.

Abstract

This study examines the social acceptance and potential for residential solar integration in Abu Dhabi to support sustainable urban innovation and prosperity. A survey of 216 Abu Dhabi residents analyzed four scenarios for incentivizing household solar panel adoption. Results demonstrate high interest and preference for governmental financial support mechanisms to spur solar integration. This research contributes an assessment framework and citizen engagement insights that could inform smart city development strategies focused on renewable energy transformation across the Gulf region. As urban centers like Abu Dhabi strive to enact their visions for economic diversification and environmental sustainability, understanding citizen perspectives on innovations like distributed solar will be critical to align technology advancement with societal needs and values. The methodology and findings of this Abu Dhabi case study provide a model to catalyze stakeholder buy-in for new energy solutions, with potential applications for other Gulf cities aiming to transition their energy systems and build integrative renewables infrastructure to power next-generation smart development. This solar integration acceptance research lays the groundwork for continued scholarly discourse and policymaker collaboration around smart cities in the Gulf that realize multidimensional progress for society, economy, and environment.

Abstract

Purpose

This paper studies the relation between corporate tax evasion, job creation and optimal fiscal policy. Job creation depends on firms’ profits since firms open (“create”) new jobs when profits increase. In turn, firms’ profits depend on incentives (rewards) and disincentives (penalties) to comply with tax rules. Hence, any fiscal policy to combat tax evasion also has repercussions on job creation.

Design/methodology/approach

This paper is both theoretical and empirical. From a theoretical point of view, a modified and extended version of the search and matching model of the labor market is used. In this framework, moreover, the welfare function of workers and firms is closely related to the job creation condition. Empirically, a panel analysis of a system of two simultaneous equations that covers 54 countries (both developed and developing) and four years (2018–2021) is carried out.

Findings

The paper finds that anti-tax evasion policies should be related to job creation policies. Also, anti-tax evasion and job creation policies change according to the extent of tax evasion in the economy. Precisely, when tax evasion is widespread, a lower tax burden (tax cuts or provision of fiscal rewards) requires tighter tax audits, whereas, where most people comply with tax rules, a decrease in tax audits is possible.

Practical implications

The empirical analysis supports the model-generated theoretical relationships. Eventually, therefore, the optimal fiscal policy suggested by this work can counteract corporate tax evasion and, at the same time, reduce the firm’s tax burden, thus promoting job creation.

Originality/value

As far as we are aware, this is the first paper that considers the close and direct link between fiscal policy, corporate tax evasion and job creation.
