Voluntary adoption of integrated reporting, effective legal system and the cost of equity
Authors: Zaro Elise , Flores Eduardo , Fasan Marco , Murcia Fernando Dal-Ri , Zaro Claudio Soerger 
Published: February 2022

PurposeIntegrated reporting (IR) provides integrated financial and nonfinancial information about companies based on the integrated thinking principle. This study aims to investigate how the cost of equity relates to IR disclosure and the impact of an effective legal system on this relationship. Effective legal system (“enforcement”) represents the strength of the legal system of a country. Although voluntary initiatives are essentially not based on regulations, the authors expect that the effective legal system will influence the implementation of such.Design/methodology/approachTo test the study’s hypotheses, linear regressions were applied using the Thomson Reuters database to analyze 20,463 firm-year observations between 2010 and 2017. The treatment group comprised companies that adopted IR; using propensity score matching, the authors defined the control group. The authors adopted a research design based on difference-in-differences to compare the cost of the capital of treatment with the control group for the periods before and after the IR adoption.FindingsThe results indicate that IR disclosure is negatively related to the cost of equity, and this negative effect is more prevalent for companies operating in high-enforcement environments.Research limitations/implicationsCost of equity is not a directly observable variable, implying that the results are sensitive to changes in the parameters that are used to compute this term. The results can help companies looking for evidence of potential effective gains of adopting IR. They also help understand that discussions related to environment, social, and governance information are somehow incorporated by analysts and investors, and reflected in the cost of raising funds.Originality/valueThis study demonstrates how IR relates to the cost of equity considering a global sample of voluntary adopters. It also analyzes the impact of institutional factors on this relationship by using a robust method of analysis. The results support the argument that companies in a strong legal system are more likely to behave sustainably and to disclose this attitude. Additionally, they are pressured to implement proposals rather than just adopting an initiative as a label.
Building world-class enterprises though mixed-ownership reform: explaining performance differences in minority and majority state-owned enterprises
Authors: Liao Hongwei , Li Mingyue , Van Assche Ari , Zheng Jiaojiao , Yang Liangping 
Published: February 2022

Purpose
In the context of China’s efforts to build world-class enterprises through mixed-ownership reform, this study aims to build an agency theory framework to analyze the differential relation between ownership structure and firm performance in majority versus minority state-owned enterprises (SOEs). It also evaluates the differential influence that political connectedness has on firm performance in the two types of SOEs.

Design/methodology/approach
Using a panel data set of Chinese state-controlled mixed-ownership enterprises covering the period 2010–2019, this paper uses ordinary least squares, random-effects, fixed-effects and three stage least squares regression analysis to study the differential impact of ownership structure and political connectedness on firm performance in majority versus minority SOEs.

Findings
In minority SOEs, firm performance is positively related to the ownership share of the largest private shareholder and state ownership positively moderates this relation. Furthermore, minority SOEs with a politically connected chairman perform worse than those with a politically connected chairman. In majority SOEs, there is no relation between the ownership share of the largest private shareholder and firm performance. In addition, majority SOEs with a politically connected chairman perform similar to those without a politically connected chairman.

Originality/value
The theoretical framework demonstrates that agency problems are substantially different in minority versus majority SOEs and that this influences how changes in ownership structure and in the type of chairman that is assigned affect firm performance. The empirical analysis confirms these predictions.
Modular framework for similarity-based dataset discovery using external knowledge
Authors: Nečaský Martin , Škoda Petr , Bernhauer David , Klímek Jakub , Skopal Tomáš 
Published: February 2022

PurposeSemantic retrieval and discovery of datasets published as open data remains a challenging task. The datasets inherently originate in the globally distributed web jungle, lacking the luxury of centralized database administration, database schemes, shared attributes, vocabulary, structure and semantics. The existing dataset catalogs provide basic search functionality relying on keyword search in brief, incomplete or misleading textual metadata attached to the datasets. The search results are thus often insufficient. However, there exist many ways of improving the dataset discovery by employing content-based retrieval, machine learning tools, third-party (external) knowledge bases, countless feature extraction methods and description models and so forth.Design/methodology/approachIn this paper, the authors propose a modular framework for rapid experimentation with methods for similarity-based dataset discovery. The framework consists of an extensible catalog of components prepared to form custom pipelines for dataset representation and discovery.FindingsThe study proposes several proof-of-concept pipelines including experimental evaluation, which showcase the usage of the framework.Originality/valueTo the best of authors’ knowledge, there is no similar formal framework for experimentation with various similarity methods in the context of dataset discovery. The framework has the ambition to establish a platform for reproducible and comparable research in the area of dataset discovery. The prototype implementation of the framework is available on GitHub.
Text mining the mission statements of the most ethical companies
Authors: Bayrak Tuncay 
Published: February 2022

PurposeThis paper explores and examines the mission statements of the most ethical companies across the globe in terms of their main purposes, values, goals, and objective, and what they say about their vision and goals.Design/methodology/approachThis study is based on the data published by the Ethisphere Institute, the global leader in defining and advancing the standards of ethical business practices. Having compiled the mission statements into a text file, the authors conducted text mining using a commercially available text mining tool SAS Enterprise Miner to survey if the most ethical companies have valued the same vision and mission such as social responsibility and ethics.FindingsA review of their mission statements indicated that some of the most ethical companies surveyed in this study such as 3M and Voya strive to be “socially responsible and ethical,” support their “societies” and respect and protect the “nature,” “planet” and “environment.” The world's most ethical companies that stress these weighted terms in their mission statements may do so to show their commitment by being socially responsible and ethical, and delivering sustainable business solutions to their customers.Originality/valueThis study provides a systematic and comprehensive exploration of mission statements of the most ethical companies in an attempt to identify patterns of differences and similarities within these statements.
Case study research in HRD: a review of trends and call for advancement
Authors: Tkachenko Oleksandr , Seo Jaekyo , Ardichvili Alexandre 
Published: February 2022

PurposeThis study aims to examine how case study research has been applied in the field of human resource development (HRD).Design/methodology/approachThe authors examined HRD case study research by analyzing 118 refereed, empirical case study articles published between 2000 and 2020 in three Academy of HRD-sponsored journals.FindingsFindings suggest that case studies have an established place in HRD research. The disciplinary convention has been exploratory case studies, which, to a greater extent, draw on single-case research designs. When examining the proportion of case study articles in relation to all empirical, peer-refereed publications in the journals, the authors found a slight decline in case study research publications in recent years. The results of our post hoc exploratory analysis indicate that HRD case study research that contributes to theory development by eliciting concepts and their relationships is likely to receive more scholarly attention than case studies that provide rich descriptions of the phenomenon. The results also suggest that it is rather case study’s contribution to theory than selected features of case study that attracts scholars’ attention.Originality/valueThe study identified several approaches to conducting case study research that have received less attention by HRD researchers. The authors encourage HRD researchers to expand their repertoire of case study approaches. The authors also provide recommendations addressing the issues of methodological self-awareness, rigor and transparency in case study research.
Procurement of facilities management services designated for office buildings of airline corporate organisations in Asia
Authors: Moktar Noorzaini , Myeda Nik Elyna 
Published: February 2022

Purpose
The purpose of this paper is to enhance decision-making process for the procurement of facilities management (FM) services within aviation corporate organisation, where the FM services functions to support the business operation. It builds on considering the fundamental elements comprising the FM procurement process from the aviation perspective.

Design/methodology/approach
The paper investigates the characteristics of the different types of sourcing approaches and the underpinning factors affecting its selection for the procurement of FM services within the aviation industry. The decision-making framework for the procurement of FM services is developed based on the qualitative case study by interview and focus group discussion with the custodian department that is directly involved in the procurement of FM services.

Findings
The degree of outsourcing is increasing due to corporate organisation’s persona. Procurement of FM services is a complex process required detailed review, efforts and time in choosing the right sourcing approach. Off the shelf guidelines for the procurement of FM services suits property professional which directly involved with the procurement of FM services. However, decision-making process for the procurement of FM services specifically for aeronautical and non-aeronautical corporate organisation are rarely found. The case study findings signify that the respondents are familiar with the in-sourcing, outsourcing and right sourcing approaches. The underpinning factors affecting sourcing approaches were categorised according to the main reasons for the procurement of FM services, considerable factors during the procurement stage and value-adding criteria. The use of strategic management tools is not widely imposed, and intelligent client guideline is not available. Hence, the decision-making framework has been developed to fill the gap in this study.

Research limitations/implications
The research is based on a study of aviation or airline corporate organisation, which limits the possibility of holistic view to the FM industry as a whole but highlights the research gap of FM procurement which is scarce within the case study of airline companies. The focus area is also bounded within the procurement of FM services designated for the office buildings.

Originality/value
The paper provides initial guideline for the airline company in sourcing the procurement of FM services that were developed based on established guidelines from accrediting bodies and scholars, as well as from the sampling feedback analysis. It is also among the firsts that examine the procurement of FM services in the context of aviation or airline industry. The outcome of this paper is a decision-making framework for the procurement of FM services that is specially designed for the airlines corporate organisations, which fills the gap that exists in the industry.
Mindfulness and stereotype threat in social media: unexpected effects for women’s leadership aspirations
Authors: Walsh Megan M. , Carleton Erica L. , Hancock Amanda J. , Arnold Kara A. 
Published: February 2022

Purpose
The purpose of this paper were to investigate whether gendered social media images reduce women’s leadership aspirations (via reduced leadership self-efficacy) and whether state mindfulness buffers the effect of stereotype threat on women’s leadership self-efficacy, and in turn, leadership aspirations.

Design/methodology/approach
Study 1 (n = 53) was a pilot study designed to test materials intended to induce stereotype threat via social media. Study 2 (n = 144) was an experimental study in which participants were randomly assigned to stereotype threat or control conditions. Stereotype threat was implicitly induced via a fictional Facebook timeline that incorporated gendered images.

Findings
Stereotype threat induced via social media predicted lower leadership aspirations for women, which was mediated by reduced leadership self-efficacy, as expected. State mindfulness moderated this mediated relationship in an unexpected way; stereotype threat effects on leadership self-efficacy and leadership aspirations were stronger for women higher in state mindfulness.

Originality/value
It is important to investigate stereotype threat induced via social media to understand the potential damage gendered images may have on women’s leadership aspirations in a modern advertising context. This research shows that indeed gendered images in social media advertising decrease women’s leadership self-efficacy and leadership aspirations. Interestingly, this study also found that mindfulness had a negative effect in relation to stereotype threat. Theoretical and practical implications are discussed.
Numerical analysis for thermal management of data center with phase change material
Authors: F. Oztop Hakan , Özgül Rıdvan , Selimefendigil Fatih 
Published: February 2022

Purpose
The purpose of this paper is to analyze the performance of a data center and thermal management by using phase change material (PCM). Numerical studies were conducted for two dimensional model of data center and installation of PCM at different locations.

Design/methodology/approach
Finite volume method was used for the unsteady problem, while impacts of air velocity and PCM location on the flow field, thermal pattern variations and phase change dynamics were evaluated. Three different locations of the PCM were considered while air velocity was also varied during the simulation. Thermal field variations and cooling performance of the system for different PCM location scenarios were compared.

Findings
It was observed that the installation of the PCM has significant impacts on the vortex formation, thermal field variation within the system and its performance. The left, right and top wall installation of the PCM changed the thermal patterns near the heat cell of the data centre. The phase change process is fast for the upper wall installation of the PCM, while the discrepancy of the melt fraction dynamics between different air flow at this position is minimum. The case where PCM placed in the upper wall at the highest air velocity is the best configuration in terms of heat storage. The utilization of PCM and changing its locations provide an excellent tool for thermal management and cooling performance of data centre.

Originality/value
Results of this study can be used for initial design and optimization of cooling systems for thermal management of data centers while the importance of the high-performance computing becomes very crucial for the advanced simulations in different technological applications.
Construction and validation of an instrument to measure workplace bullying
Authors: Na-Nan Khahan , Virakul Busaya , Piriyakul Montree , Russ-Eft Darlene Fern 
Published: February 2022

Purpose
This paper aims to develop and test an instrument to measure workplace bullying in the Thai context.

Design/methodology/approach
The research has three phases. Phase 1 involved the development of an instrument and constructs/items as well as testing of content validity and reliability. Phase 2 used exploratory factor analysis to identify the appropriate constructs and items to be included in the instrument. Phase 3 consisted of confirmatory factor analyses to confirm that the measurement instrument built in this research is effective for measuring workplace bullying. Data were collected through interviews of experts and stakeholders in human resource (HR), and through online questionnaires completed by 340 HR employees in Thailand.

Findings
Results revealed that workplace bullying can be classified into three types: work-related bullying, personal-related bullying and physical-related bullying. Findings confirmed the constructs using theoretical concepts and empirical evidence with values of χ2 = 120.473, df = 98, p = 0.061, χ2/df = 1.229, goodness of fit index = 0.961, adjusted goodness of fit index = 0.938, Tucker-Lewis Index = 0.992, comparative fit index = 0.994 and root mean square error of approximation = 0.026.

Research limitations/implications
The findings of this study add further knowledge to the field of organizational behaviour and could be valuable for developing management theories regarding building an effective work climate. The three types of workplace bullying (work-related, personal-related and physical-related bullying) can be studied as independent, dependent or mediating variables that can both influence and mediate. Results can be used to explain behavioural aspects of workplace bullying in clear and accurate terms.

Practical implications
The developed instrument can accurately measure levels of workplace bullying behaviours of employees in different organizations with high levels of validity and reliability. Results can be used to develop interventions and guidelines for managing or reducing workplace bullying of employees. The instrument can also be used as a research tool for further studies of bullying behaviour.

Social implications
Diversity, equality and sustainability are characteristics of organizations that have developed an effective and happy work culture. Allowing workplace bullying to occur can negatively affect such a productive organizational climate. Therefore, the research findings have social implications in terms of their ability to monitor workplace, as well as community bullying.

Originality/value
The instrument to measure workplace bullying was developed and improved by blending Western concepts with interview data about workplace bullying behaviours experienced by HR employees in Thailand. The instrument can facilitate the measurement of employee bullying levels in companies and can contribute to future studies of bullying behaviours in organizations or workplaces.

Consumer preferences for innovative and traditional last-mile parcel delivery
Authors: Merkert Rico , Bliemer Michiel C.J. , Fayyaz Muhammad 
Published: February 2022

PurposeThe purpose of this research is to reveal consumer preferences towards innovative last-mile parcel delivery and more specifically unmanned aerial delivery drones, in comparison to traditional postal delivery (postie) and the recent rise of parcel lockers in Australia. The authors investigate competitive priorities and willingness to pay for key attributes of parcel delivery (mode, speed, method and time window), the role of contextual moderators such as parcel value and security and opportunities for logistics service providers in the growing e-commerce market.Design/methodology/approachA survey involving stated choice experiments has been conducted among 709 respondents in urban Australia. The authors estimated panel error component logit models, derived consumer priorities and deployed 576 Monte Carlo simulations to forecast potential delivery mode market shares.FindingsThe study results suggest that people prefer postie over drone delivery, all else equal, but that drone deliveries become competitive with large market shares if they live up to the premise that they can deliver faster and cheaper. Both drone and postie become less attractive relative to parcel lockers when there is no safe place to leave a parcel at a residence, highlighting the importance of situational context and infrastructure at the receiving end of last-mile delivery. The authors identified opportunities for chargeable add-on services, such as signature for postie and 2-h parcel deliveries for drones.Originality/valueThe authors offer timely and novel insights into consumers preferences towards aerial drone parcel deliveries compared to postie and lockers. Going beyond the extant engineering/operations research literature, the authors provide a starting point and add new dimensions/moderators for last-mile parcel delivery choice analysis and empirical evidence of market potential and competitive attributes of innovative versus traditional parcel delivery alternatives.
