The purpose of this paper is to present a preliminary work on extracting band gap information of materials from academic papers. With increasing demand for renewable energy, band gap information will help material scientists design and implement novel photovoltaic (PV) cells.

The authors collected 1.44 million titles and abstracts of scholarly articles related to materials science, and then filtered the collection to 11,939 articles that potentially contain relevant information about materials and their band gap values. ChemDataExtractor was extended to extract information about PV materials and their band gap information. Evaluation was performed on randomly sampled information records of 415 papers.

The findings of this study show that the current system is able to correctly extract information for 51.32% articles, with partially correct extraction for 36.62% articles and incorrect for 12.04%. The authors have also identified the errors belonging to three main categories pertaining to chemical entity identification, band gap information and interdependency resolution. Future work will focus on addressing these errors to improve the performance of the system.

The authors did not find any literature to date on band gap information extraction from academic text using automated methods. This work is unique and original. Band gap information is of importance to materials scientists in applications such as solar cells, light emitting diodes and laser diodes.

This paper aims to analyze the potential variables explaining the compliance value added tax (VAT) gap, which basically represents an estimate of the unpaid VAT in the economy. A major component of compliance VAT Gap is represented by tax fraud; there exist other causes too, like insolvencies, bankruptcies, optimizations practices and maladministration. The objective of our paper is to revisit the main determinants of the VAT compliance gap for the European Union (EU)-27 member states. Using econometric modeling, our study identifies the relationship between the VAT gap and various determinants of it.

Our work focuses on the shadow economy, final consumption, VAT revenues, standard VAT rates, differences between the standard and reduced rates, economic prosperity, press freedom, political stability and others, as determinants of European VAT compliance gaps, for the 2005–2020 time interval. The methods include panel data analysis through simple and multiple regression modeling, the combinatorial approach, fixed and random effects.

Our study validates the direct impact of shadow economy and the indirect impact of VAT revenues, economic prosperity and press freedom, upon VAT compliance gaps. Upon subsampling of EU member states within old and new ones, our results estimate a larger positive impact of shadow economy upon old member states, compared to new ones.

The policy implications include leverage effects of governments acting upon a reduction in shadow economy phenomena and boosts of economic development, political stability and press freedom, in order to attain the contraction of compliance VAT gaps.

Our paper sheds light in a poorly explored scientific area, that of the determinants of VAT gap, especially in relationship with financial and economic crime phenomena.

The purpose of this study is to explore gender gaps, values and practices in a Sub-Saharan African (SSA) country, specifically to identify gender inequality in Kenyan leadership and propose suggestions for advancing gender equity.

This Kenya study replicated the research design of the Global Leadership and Organizational Behaviour Effectiveness Project for gathering country data. It sampled middle and upper management in the commercial sector (finance and agriculture) and added the civic sectors of health care and education, using quantitative research (267 managers in over 100 organizations) and qualitative research design (30 interviewees from 23 organizations).

Gender had no apparent effect on leadership attributes nor on preferred modes of leadership. Statistical and thematic analysis revealed conflicting values and behaviours regarding gender equality and leadership. A high cultural dimension score on practices reflects a traditional leadership approach for male dominance, referred to as the Bwana Kubwa model. However, a high value score for gender equality reflects a more contemporary perspective, identified as the Inspirational Idealist. The gender gap presents a cultural paradox and a leadership constraint.

The Inspirational Idealist model advances African leadership theory as it identifies a preferred value-based paradigm of effective performance-based leadership. This is contrary to the prevalent patriarchal practices of the Bwana Kubwa (Big Boss) model, which reflects biased gendered preference.

Male and female leaders need to challenge the status quo and align leadership practices with the articulated cultural values expressed as an Inspirational Idealist model. It has considerable relevance to advancing African leadership theory and informing culturally relevant policies and contextualized practices focused on gender equity in leadership.

This research on practices and values pertaining to gender equality of Kenyan managers is the first in-depth managerial leadership study of any SSA country. It is unique in that it broadened the scope of study to include professional sectors, gender, age and ethnicity variables.

It is known that a conflict exists between consumers’ materialistic and green values. Previous research has focused on values conflict consequences. Antecedents of consumers’ materialistic and green values conflict remain understudied. This study aims to explore the antecedents of consumers’ materialistic and green values conflict.

An exploratory type research design was applied. Overall 22 interviews were conducted with consumers that had materialistic and green values conflict. The transcripts of the interviews were analyzed using content analysis with Maxqda software.

The findings demonstrate consumers' negative attitudes towards consumption, understood as consumerism. Results indicate that value conflict is related to unpleasant emotions such as guilt, anxiety, helplessness and remorse. Guilt is the most prominent emotion associated with the conflict of values. The study identifies dissonant information, environmental knowledge, social norms, impulsive buying and mindfulness as antecedents of materialistic and green values conflict.

The novelty of the study is the antecedents of the materialistic and green values conflict. This study makes a valuable contribution to the academic discourse on sustainable consumption, consumer materialism and green values by providing a deeper understanding of the values conflict experienced by consumers who hold materialistic and green values. The main significance of this study is that it provides valuable insights from qualitative research into the antecedents of the conflict between consumers' materialistic and green values.

Infrastructure forms a basis for the operations and sustainability of the modern society. This paper aims to recognize value creation from the infrastructure procurement ecosystem perspective to achieve those goals. The pursuit of enhancing value creation involves an examination of infrastructure procurement challenges, boundaries as well as boundary spanners that facilitate effective knowledge transfer and interaction.

The qualitative study is based on content analysis of 25 thematic interviews. Data was transcribed and coded via Atlas.ti software.

Infrastructure procurement value creation challenges appear complex and related to boundaries that hamper collaboration, coordination and knowledge sharing. Our results show that these boundaries locate within and between different levels of procurement ecosystem. Therefore, value creation in infrastructure procurement requires boundary spanners for leveraging knowledge sharing and interaction. Artifacts, discussion, processes and brokers as identified boundary spanners are strongly nested and interrelated in the industry. Special attention should be given to supporting individuals to act as brokers, since they play the key roles in trust building, culture steering and usage of other boundary spanners.

Promoting value creation in infrastructure procurement helps to achieve socio-economic development goals.

This study offers a unique perspective on value creation in the context of infrastructure by adopting an ecosystem lens and examining boundary crossing mechanisms. The results support future development of collaboration and knowledge sharing practices fostering procurement productivity.

The purpose of this paper is to explore the matching relationship between factor endowment and industrial structure, and its impact on economic growth.

The assortative matching method is developed to quantitatively measure the matching between factor endowment and industrial structure. A series of empirical tests are then carried out to evaluate the impact on the economic development of the matching.

1) The matching between factor endowment and industrial structure has a significantly positive impact on economic growth. (2) Economic growth reaches its maximum when the gap between the two sectors narrows to zero. (3) This effect is particularly significant for countries with higher GDP per capita and GNI per capita. (4) The results remain robust after employing a series of tests.

Aggressive industrial policies are not desirable. The optimal industrial structure is the one that complied with the comparative advantage of the given factor endowment in the economy.

So far, there has been a significant lack of an applicable quantitative indicator for measuring the matching between factor endowment and industrial structure, which is essential for conducting empirical tests and providing evidence for related economic theories.

The sale of second-hand goods in the luxury fashion space continues to soar. However, existing literature on this segment is limited and the factors that draw consumers to this space are not well understood. This study aims to fill this gap and proposes a conceptual model demonstrating the linkage between the motivators and barriers toward re-commerce in the luxury fashion space and actual shopping behaviors.

A survey sample of USA second-hand luxury fashion shoppers was collected. Participants were asked questions about various motivators and barriers toward re-commerce, as well as the participants' attitudes and shopping behavior. The results were analyzed using SmartPLS structural equation modeling (SEM).

Economic reasons, originality and self-extension were found to be statistically significant motivators of attitudes toward re-commerce, while status consumption, nostalgia and ecological motivators were not. Superstitious beliefs were also found to be statistically significant motivators toward attitudes of re-commerce. Attitudes were also found to be a significant predictor of shopping behavior as measured by dollars spent and shopping frequency.

This study is among the first to propose a conceptual model depicting the relationship between motivators and barriers to actual shopping behavior in the second-hand luxury fashion space. Many of the motivators and barriers examined in this study are novel and have not been considered in prior research. Superstitious beliefs in particular have not been studied in the context of re-commerce.

Entrepreneurship studies have established various antecedents leading to eventual entrepreneurship by measuring entrepreneurial intention (EI). However, evidence has shown that intention does not necessarily translate into behaviour, especially for complex behaviours such as creating a business venture. Hence, this paper aims to examine how contextual and individual factors interact with one another to promote or inhibit one’s translation of EI into entrepreneurial action in an emerging economy.

The authors adopt a retrospective qualitative approach by interviewing 37 Malaysian micro and small business owners. Then, multidimensional scaling is used to examine the interactions between the identified factors.

The authors find that social networks are the main influence on an individual’s propensity to start a business – it provides financial and social capital, provides other means of support such as practical help and business opportunities and instils passion and drive. Furthermore, organisations such as schools, universities and employers play an important role in instilling the motivation for a career shift to entrepreneurship and by providing opportunities to upskill. In addition, the findings indicate that entrepreneurial traits such as proactiveness, resourcefulness and passion enable individuals to overcome entrepreneurial structural constraints, such as lack of resources and negative action-related emotions. By contrast, the role of macro-environmental factors such as governmental support play less prominent roles in the narratives of the entrepreneurs.

This study has important implications for governments and policymakers in implementing support for those transitioning from salaried employment to self-employment and for entrepreneurship interventions to adopt a holistic approach that encompasses building one’s entrepreneurial knowledge, skills and mindsets, alongside providing external incentives.

The authors provide a more holistic approach to exploring the EI–behaviour gap. In addition, this study explored facilitators and barriers to entrepreneurship specific to the context of an emerging economy such as Malaysia, which is highly dependent on small-scale self-employment.

This paper aims to examine how neighborhood characteristics (income, population composition) and individual building attributes (ownership) affect the recovery period of single-family housing and determine their correlations with property abandonment and changes in residential land use after natural disaster.

This empirical study focuses on Valley Fire, one of the California’s most destructive wildfires in 2015, and uses assessor, community, demographic and sales data to measure recovery of a panel of single-family houses located in Lake County in California between 2012 and 2020. Several regression and correlation models will be developed to test different hypotheses.

This study found that: Recovery period is longer than what expected in most existing literature; ownership status significantly affects recovery period; income level is not a significant factor for shortening the recovery period; and minorities may need more assistance for constant recovery. Findings of this research will help identify at risk communities to avoid uneven housing recovery and lower the rate of property abandonment.

Housing recovery is key to revitalizing communities following major natural disasters. The sociodemographic characteristics of each neighborhood have significant impact on the duration of recovery and possible property abandonment. Understanding how home and neighborhood characteristics affect recovery will help planners prevent long-lasting adverse effects of natural disasters.

The objective of the paper is to explore the relationship among perceived quality value, hedonic value, social value, price value, customer engagement and customer-based brand equity using stimulus-organism-response (S-O-R), customer engagement and customer-perceived value theories for digital payment apps. In addition, the study examines the mediating role of customer engagement between customer value dimensions and customer-based brand equity and analyzes the moderating role of age.

Partial least squares-based structural equation modeling was used to test the proposed hypotheses through a sample of 316 respondents who used digital payment apps.

The findings indicate that customer engagement mediates the relationship between customer value dimensions and customer-based brand equity. Age does not moderate the relationship between customer value dimensions and customer engagement. The study confirmed the pronounced effect of specific paths for various age groups.

This study contributes novel insight to S-O-R, customer engagement, and customer value research.
