This paper aims to investigate the usefulness and validity of student evaluations of teaching (SET) by estimating multiple biases and their cumulative effect, and assessing their implications for evaluating teaching effectiveness.

The study uses a rich dataset from a Polish university and applies linear and quantile regressions to estimate SET biases, including course difficulty, class size and instructor characteristics. The cumulative effect of these biases is measured, and changes during the COVID-19 pandemic are analyzed to assess their impact on SET scores.

The cumulative SET bias reaches more than one point on a 1–5 Likert scale, challenging the reliability of raw SET scores. Significant asymmetries exist between low and high SET scores. Poor initial evaluations of a teacher predict future low performance ratings, while top-rated teacher contests are often influenced by chance rather than teaching quality.

The findings suggest universities should discontinue using raw SET scores for faculty evaluation and instead implement adjustments for identified biases. This approach will provide a more accurate measure of teaching performance.

This paper builds on earlier studies that applied econometric frameworks to analyze SET bias predictors and offers a novel, comprehensive assessment of cumulative SET biases and their asymmetries. It is the first to evaluate the effects of multiple SET biases within a single model and the first to document how SET biases intensified during the pandemic, emphasizing the need for significant reform in teaching evaluation practices.

Energy saving in student housing has become a major challenge in the growing tertiary higher learning institutions in Africa. The purpose of this study is to evaluate the drivers of changes in energy-saving behaviours in student housing in Ghana.

This study is quantitative based on the theory of planned behaviour. A survey of 1,702 on-campus university student housing users in Northern Ghana was conducted using a simple random sampling technique. Behavioural drivers were conceptualised into two broad themes and analysed using the Partial Least Square Structural Equation Model tool.

The findings of this study accept the general view that behavioural factors affect energy saving. However, financial, indoor environmental quality and student housing energy management techniques positively determine changes in energy-saving behaviours in student housing than behavioural factors. Knowledge-related factors did not show any contribution to behavioural intentions of energy saving.

An all-inclusive energy-saving mechanism, highlighting improvement in student housing conditions, can enhance energy saving. Aside from this, increasing the attention to sustainability and energy efficiency programs in student housing environments can provide positive potential for energy saving in student housing.

Introducing the theory of planned behaviour in similar studies confirms the large contributions of behavioural drivers to energy saving. The additional exploration of other drivers in this study showcases the potential of influencing energy-saving decisions in student housing within the sub-Saharan sub-region.

This paper uses the cultural figure of Willy Wonka to explore the archetype of the “boy-entrepreneur”, and what the various film manifestations of Wonka (1971–2023) say about changes in entrepreneurial masculinity. We (1) develop an original conceptualisation of boyhood as creatively, socially and gender liminal, (2) analyse the entrepreneurial archetype using literary theories and (3) provide a novel interpretation of Apollonian and Dionysian masculinity to aid future cultural analysis of founder/innovator depictions in children’s media.

Our study conducts a three-stage dramaturgical analysis of the major film adaptations of Roald Dahl’s Willy Wonka (1971, 2005 and 2023). After supplementing the limited literature on boyhood in entrepreneurship with literary and feminist art theory, we identify the significant narrative features which frame the Wonka dramas and produce a framework which tracks thematic changes across the films in terms of the creative, social and gender liminal elements of Wonka’s boy-entrepreneur identity.

Our interpretive analysis reveals a gradual shift in values expressed through Wonka’s boy-entrepreneurialism away from a more hegemonic, Apollonian style of masculinity towards a more Dionysian style embracing emotional expression, intimacy with female characters and kin, and collaborations with nature. Such shifts reflect the growing influence of non-hegemonic entrepreneurial gender expressions, value-driven and relational approaches to new venture creation.

The study contributes to the hugely unexplored area of the “boy-entrepreneur”/“boy-genius”, demonstrating its durability in reality, imagination and popular culture. We provide an in-depth character portrait to provoke further attention to children’s multi-media ways of experiencing early entrepreneurial impressions. We also expand the methodological scope of research on entrepreneurial masculinity beyond real-life founders.

As China is on an inevitable march into the digital era, firms have accumulated abundant digital assets, such as algorithms and data. Facing the possibility of using digital assets as a new type input, besides traditional inputs such as capital and labor, would powerful managers perform better? Would managerial power help managers increase the efficiency of how a firm combines traditional and digital inputs and converts them into outputs? Thus, the purpose of this study is to investigate whether powerful managers promotes corporate productivity by using digital assets as a new input.

Using data from listed Chinese firms between 2008 and 2020, the authors constructed panel regressions with three-way fixed effects to examine whether and how managerial power influences corporate productivity in the current digital context, particularly under market uncertainty.

The findings reveal no consistent relationship between managerial power and corporate productivity. The results explain this from two contrasting effects: while managerial power promotes technological change it hinders technical efficiency – two components of total productivity. Moreover, this study identifies market uncertainty as a significant external contingency. In uncertain markets, strong managerial power positively impacts corporate productivity.

The results extend extant theoretical insights in the literature on how managerial power might influence corporate productivity.

While innovative building materials (IBM) have emerged as a promising solution for addressing the global construction industry’s environmental, economic and social challenges, their adoption is plagued with increasing challenges in the Nigerian construction industry (NCI). To provide practical strategies to overcome the present IBM challenges in the NCI, the barriers that hinder its successful adoption need detailed investigation. Consequently, this study examines the barriers that affect the adoption of IBM for sustainable construction (SC) in the NCI.

A quantitative research approach was used to obtain primary data from 282 construction professionals, viz. architects, builders, engineers and quantity surveyors, via a closed-ended questionnaire survey. Data were analysed using a mean item score (descriptive analysis) and exploratory factor analysis (inferential analysis).

The study revealed the top five most significant barriers to IBM adoption in the NCI. These barriers include lack of awareness and knowledge, learning/training period, cost and economic viability, lack of qualified staff and lack of end-user involvement. Factor analysis revealed five components of barriers: resource and policy-related barriers, perception and cultural-related barriers, organisational-related barriers, awareness and market-related barriers and resistance and stakeholder engagement-related barriers.

The findings of this study have several practical implications for construction professionals, policymakers and other stakeholders in Nigeria. The study highlights the need for increased awareness and technical expertise to promote the adoption of IBM in the NCI. The study also recommends several practical strategies for overcoming the barriers to IBM adoption and promoting SC practices in Nigeria, such as fostering a positive perception of sustainable concepts, fostering stakeholder support and involvement and promoting a more conducive environment for adopting sustainable practices. The implication of this study transcends the local context, offering a model for other countries to consider, thereby contributing to a global shift towards sustainable construction practices.

The findings highlight the critical role of societal attitudes and awareness in adopting IBM, suggesting the need for educational and awareness programmes to shift public and organisational perception. This shows the importance of cultural change and societal readiness to embrace sustainable construction practices.

This study contributes significantly to knowledge of the barriers to adopting IBM for SC in NCI. Findings from the study will inform policymakers, industry professionals and other stakeholders about the key barriers that require attention and intervention, facilitating the initiatives to overcome these barriers effectively.

The purpose of this study is to contribute to empirical research on individual ambidexterity drivers. This paper analyzes the relationships between inclusive leadership, team knowledge acquisition, team knowledge sharing, digital tools usage and individual ambidexterity.

This study conducted a questionnaire survey of high-tech and manufacturing enterprises in China and obtained 75 leader questionnaires and 365 employee questionnaires. The hypotheses were tested using hierarchical and cross-level regressions.

The research indicates that inclusive leadership improves team knowledge acquisition and sharing. However, only team knowledge sharing significantly boosts individual ambidexterity, and not team knowledge acquisition. Thus, inclusive leadership fosters individual ambidexterity primarily through team knowledge sharing. Digital tools usage strengthens the impact of inclusive leadership on team knowledge sharing, thereby intensifying its effect on individual ambidexterity. However, digital tools usage weakens the effect of inclusive leadership on team knowledge acquisition.

First, this study addresses the call for research on ambidexterity at different levels, revealing the heterogeneous impact of team knowledge acquisition and sharing on individual ambidexterity. Second, this study developed a theoretical model to explore how leadership affects individual ambidexterity. Third, this study responds to the question that digitalization has won, but has leadership lost by investigating the role of digital tools usage in the relationship between inclusive leadership and team knowledge integration.

Ubiquitous penetration of the internet fuelled by the interactive nature of digital media has created a new genre of entrepreneurs who leverage social media to propel their businesses. This study aims to explore the transformation of one such digital entrepreneurial cohort: Food YouTubers (YTs), who have metamorphosed from being mere content creators to entrepreneurs in the context of an emerging economy.

The authors invoke a qualitative interpretive phenomenological approach to unravel the entrepreneurial transition process. A combination of personal interviews and open-ended surveys is used to collect relevant data from 14 digital entrepreneurs. The transcripts are analysed to extract meaningful codes and themes.

The study shows that these entrepreneurs’ innovativeness and readiness to meet the real-time demands of their customers made their ventures a runaway success. This is the first study to target food YTs in India, an emerging economy. While the study is exploratory in nature, it provides basic insights into the transition of a novel group of influencers into entrepreneurs.

To the best of the authors’ knowledge, this is the first study of its kind to analyse the transition of YouTube influencers into entrepreneurs in emerging economies, as it relies more on entrepreneurial activities for their economic and social well-being.
