Do CEO's attributes increase risk-taking? Empirical evidence from France
Authors: Loukil Nadia , Yousfi Ouidad 
Published: June 2022

PurposeThe current paper studies how CEO attributes could influence corporate risk-taking. The authors examine the effects of CEO demographic attributes and CEO position's attributes on financial and strategic risk-taking.Design/methodology/approachThis study is drawn on non-financial firms listed on the SBF120 index, between 2001 and 2013.FindingsFirst, long-tenured CEOs are prone to decrease the total risk and the leverage ratio. Second, despite the many CEOs have political connections; they are not prone to engage in risky decisions not serving the business' interests. Third, old CEOs are likely to rely on debt to fund internal growth. Moreover, business and science-educated CEOs behave differently in terms of risk-taking. Finally, the authors show that CEOs' attributes have less influential effects in family firms than in non-family firms. Also, they seem to have more significant associations with risk-taking during and after the financial subprime crisis.Originality/valueThis paper examines how cognitive traits could shape investments decisions, in terms of risk preferences.
Scenarios for optimizing timing for new product exits: a trifecta of models' predictive performances
Authors: Sharma Priyanka , Lichtenthal J. David 
Published: June 2022

PurposeThe purpose of the study is applying and comparing models that predict optimal time for new product exit based on its demand pattern and survivability. This is to decide whether or not to continue investing in new product development (NPD).Design/methodology/approachThe study investigates the optimal time for new product exit within the hi-tech sector by applying three models: the dynamic learning demand model (DLDM), the generalized Bass model (GBM) and the hazard model (HM). Further, for inter- and intra-model comparison, the authors conducted a simulation, considering Weiner and exponential price functions to enhance generalizability.FindingsWhile higher price volatility signifies an unstable technology, greater investment into research and development (R&D) and marketing results in higher product adoption rates. Imitators have a more prominent role than innovators in determining the longevity of hi-tech products.Originality/valueThe study conducts a comparison of three different models considering time-varying parameters. There are four scenarios, considering variations in advertising intensity and content, word-of-mouth (WOM) effect, price volatility effect and sunk cost effect.
Bankruptcy courts and the marketization of bond issuance
Authors: Huang Xinyi , Teng Fei , Xin Yu , Xu Liping 
Published: June 2022

PurposeThis paper aims to study the effect of the establishment of bankruptcy courts on bond issuance market. This paper helps to predict that the introduction of bankruptcy courts in China can mitigate price distortions caused by the implicit government guarantees and promote the development of the high-risk bond market.Design/methodology/approachThis paper exploits the staggered introduction of bankruptcy courts across cities to implement a differences-in-differences strategy on bond issuance data. Using bonds issued in China between 2018 and 2020, the impact of bankruptcy courts on the bond issuance market can be analyzed.FindingsThis paper reveals that bond issuance credit spreads increase and is more sensitive to firm size, profitability and downside risk of issuance entity after the introduction of bankruptcy courts. It also reveals a substantive increase in bond issuance quantity and a decrease in issuer credit ratings following the establishment of bankruptcy courts. In addition, the increase of credit spreads is more prominent for publicly traded bonds, those whose issuers located in provinces with lower judicial confidence, bonds issued by SOEs and bonds with stronger government guarantees. Finally, the role of bankruptcy courts is more pronounced in regions with higher marketization.Originality/valueThis paper relates to previous studies that investigate the impact of laws and institutions on external financing. It helps provide new evidence to this literature on how improvements of efficiency and quality in bankruptcy enforcements relate to the marketization of bond issuance. The results provide further evidence on legal institutions and bond financing.
ESG and performance in public health-care companies: the role of disclosure and director liability
Authors: El Khoury Rim , Nasrallah Nohade , Toumi Amina 
Published: June 2022

Purpose
The seepage of companies' capital accommodated by weak country-level institutions is inconducive to building sustainable businesses. Companies' performance on environmental, social and governance (ESG) issues is still a challenging question. This study aims to test the predictability of ESG on the performance of the health-care industry from a global perspective, while accounting for the country disclosure and director liability indices and performing robustness tests.

Design/methodology/approach
This study relies on panel data of 912 companies operating in 38 different countries for 2012–2020. This study controls for firm-level variables (leverage, size and loss), macroeconomic variables (COVID, gross domestic product and inflation) and institutional variables.

Findings
Findings indicate that countries with different levels of disclosure exhibit different patterns. Distinctly, the environmental pillar has a concave impact on return on assets, and the role of the disclosure index greatly manifests with the environmental pillar.

Practical implications
This study ponders the impact of country disclosure on sustainability practices from a global health-care perspective.

Originality/value
This paper is original, as it addresses the relationship between ESG performance and financial performance while accounting for the impact of institutional factors such as the business disclosure and director liability indices.
Gautrain: contextualising strategic leadership of African rapid rail
Authors: Mthombeni Morris , Scheepers Caren Brenda , Mgedezi Viwe 
Published: June 2022

Learning Outcomes
After working through the case and assignment questions, students will be able to do the following: • Analyse the aspects of strategic leadership and evaluate effectiveness of the leadership in the case study. • Identify stakeholders in a large-scale project and differentiate between their needs and sources of power. • Establish what behavioural mechanisms can be used by leaders to gain support from stakeholders with seemingly divergent pro-poor and pro-growth development orientations for expansion in an emerging market context. • Generate recommendations to communicate the benefits of expansion plans.

Case overview/synopsis
On November 8, 2019, Jack van der Merwe, the chief executive officer of the public rapid rail organisation, Gautrain Management Agency (GMA), was considering how to influence stakeholders to support the pace of the expansion planning phase, without alienating the surrounding communities and balancing the various and sometimes opposing stakeholder interests. The case highlights the background to this dilemma in offering the financial background of the Gauteng province and the evolution of the Gautrain project in the context of an emerging market country characterised by institutions at different development levels and how the unique characteristics of the protagonist could influence stakeholder orientations. The case illustrates how the Gautrain is at the centre of a complex transport conflagration in the South African transport ecosystem. Specific stakeholders and their needs are exposed in the case to enable students to analyse their several levels of influence on the project and proposed expansion. The differences between pro-poor and pro-growth development orientations are also highlighted in this case as input to describe the dilemma Van der Merwe faced in his influencing role in this particular South African context. Students will gain insight into how to manage the tensions between pro-poor and pro-growth orientations.

Complexity academic level
The case is suitable for a graduate-level course on strategy; organisational behaviour; or leadership. The case is also suitable for a post-graduate-level course on an MBA or MPhil program on strategy and leadership.

Department chairs’ perceptions of union membership on academic human resource decision-making
Authors: Dzwik Leigh Settlemoir , Park Sunyoung 
Published: June 2022

Purpose
The purpose of this study is to explore unionization’s impact on university department chairs for academic human resource decision-making in terms of faculty hiring; re-employment, promotion and tenure; other faculty evaluation decisions; and discipline and discharge.

Design/methodology/approach
The subjects were department chairs with more than one year of experience in institutions with faculty bargaining units in the USA. Half of the department chairs were members of the bargaining unit and half were not members of the bargaining unit. T-test and Chi square statistics were used to examine and compare 136 chair responses.

Findings
While there were significant differences between the groups when making all academic human resource decisions based on role affiliation, there was a weak identification as a bargaining unit member. There was no difference between groups when determining how the participants perceived the process rules, and the majority of the responses indicated membership in the union does not complicate making academic human resource decisions.

Originality/value
Based on these findings, this study provides the first empirical evidence against a long-held administrative belief department chairs should not be unionized as they will side with union colleagues in difficult academic human resource cases. The findings of this study also produce three key recommendations for practice and faculty development.
Computational fluid dynamics simulation and experimental investigation of a thermoelectric system for predicting influence of applied voltage and cooling water on cooling performance
Authors: Ceviz Mehmet Akif , Afshari Faraz , Muratçobanoğlu Burak , Ceylan Murat , Manay Eyüphan 
Published: June 2022

Purpose
The purpose of this paper is to experimentally and numerically investigate the cooling performance of the air-to-water thermoelectric cooling system under different working conditions.

Design/methodology/approach
An air-to-water thermoelectric cooling system was designed and manufactured according to the principle of discrete binary thermoelectric Peltier modules, and the thermal performance, heat transfer rate and average COP values were examined at different cooling water temperatures and voltages applied. Additionally, numerical simulations were performed by computational fluid dynamics approach to investigate the temperature distribution and airflow structure inside the cooling chamber.

Findings
Analyses were performed using experimental tests and numerical methods. It was concluded that, by decreasing the cooling water temperature from 20 to 5 °C, the average COP increases about 36%. The voltage analysis showed that the efficiency of the system does not always increase as the voltage rises; more importantly, the optimum voltage is different and depends on whether it is desired to increase COP or increase the cooling rate.

Originality/value
In the studies published in the field of thermoelectric cooling systems, little attention has been paid to the voltage applied and its relationship to other operating conditions. In most cases, the tests are performed at a constant voltage. In this study, several options, including applied voltage and cooling water temperature, were considered simultaneously and their effects on performance have been tested. It was found that under such studies, optimization work should be done to evaluate maximum performance in different working conditions.

Authors: Moreno-Manzo Jessenia , Gassiot-Melian Ariadna , Coromina Lluís 
Published: June 2022

PurposeThe city of Quito is a World Heritage Site (WHS) in Ecuador and the city owns one of the best-preserved and extensive historic centers in Latin America for cultural tourism. This study aims to identify the factors that constitute perceived value construct at the WHS of Quito.Design/methodology/approachThis research collects data from tourists who have visited the city of Quito, Ecuador. A total of 381 on-site questionnaires are used. Data have been analyzed using exploratory factorial analysis.FindingsResults regarding the dimensional structural framework of perceived value indicate that perceived value at the WHS of Quito has five factors: (1) monetary and non-monetary costs (MNC), (2) staff service quality (SSQ), (3) tourist offer accessibility (TOA), (4) destination attractiveness (DA) and (5) information accessibility (IA).Originality/valueTwo new factors of accessibility have been proposed in this study for measuring consumer value at a WHS. Perceived value and accessibility have been treated as two separate subjects in academic literature before. However, this article contributes to the understanding of perceived value at WHS, including factors linked to accessibility. Both managerial and theoretical implications for WHS are discussed.

Authors: Jimenez Andrea , Vannini Sara , Cox Andrew 
Published: June 2022

PurposeThe aim of this paper is to introduce a holistic decolonial lens for Library and Information Studies (LIS). As such it centres in the following questions: what does decolonisation mean in the context of LIS? How can a holistic approach help improve our understanding of the field?Design/methodology/approachThis is a conceptual paper that draws on theoretical analysis and discussion with in-depth examination of two cases of librarianship and information for development.FindingsThe paper presents a decolonial framework for interpreting and comprehending LIS-specific issues. As a result, we believe it is critical to recognise three interconnected types of colonial legacies and identify ways in which LIS academics and practitioners can consider these in the context of their research and work.Research limitations/implicationsThe paper introduces a holistic framework for thinking about decoloniality in the LIS discipline. Further work should consider how this framework can be useful for other LIS fields.Practical implicationsThe framework is of practical significance for LIS academics and practitioners who wish to take a decolonial approach to their research and thinking. We provide questions intended to lead to action.Originality/valueThe paper provides a holistic decolonial approach to critically reflect on research and teaching practices in the context of LIS.
How online communities are important for rural entrepreneurial change – the library revolt
Authors: Jonsson Josefina , Gaddefors Johan 
Published: June 2022

Purpose
This study aims to discuss how an online community interacts with a local community during the entrepreneurial process. By having a contextualized view of entrepreneurship, this study acknowledges the social and spatial dynamics of the process.

Design/methodology/approach
The inductive approach used in this study is empirically anchored in the case “the library revolt”. This paper analysed interviews conducted in a selected region in Sweden and followed a netnographic method to capture the social interactions online. By using qualitative modes of inquiry, this study attempts to illuminate the social aspects of the entrepreneurial process.

Findings
This study shows how social media works as a contextual element in entrepreneurship. By presenting interactions between an online community and a rural community, it is shown how entrepreneurial processes in rural areas can be shaped not only through local community relations but also by online interaction. It illustrates how an online context, where actors are located with their own unique set of resources, contributes to rural development. By being a part of an ongoing process of structuration, we can view the actors are gaining access to the resources online, which contributes to the change happening in a local community.

Originality/value
This study adds to the conversation of the role of context in entrepreneurship studies. Rural entrepreneurship largely discusses the local social bonds and actions, while this study includes the online social bonds as a part of the reality in which entrepreneurship is developed.

Eco-friendly single bath dyeing of wool yarns with extracted cochineal dye: optimization and additives effect
Authors: Imani Hooman , Gharanjig Kamaladin , Ahmadi Zahra 
Published: June 2022

Purpose
The purpose of this study is simultaneous dyeing and mordanting of wool yarns with extracted cochineal dye and aluminum sulfate to the reduction of consuming energy, water and time.

Design/methodology/approach
The dyeing process was optimized using the response surface methodology (RSM) approach. pH, dyeing duration and the presence of additives were chosen as variables and the color strength of samples as a response. The color characteristics and fastness attributes of samples dyed in the best condition were evaluated and compared to pre-mordant dyeing outcomes on wool yarns.

Findings
The best conditions for deep dyeing wool with cochineal dye were as follows: pH 2.5, time 110 min and the ratio of aluminum: additives 1:0 at 100 °C. Color strength of dyed wool yarns by one-bath and pre-mordant dyeing methods were approximately the same. Wool yarns can dye to the on-bath dyeing method such that the dyed samples have similar color strength and fastness properties to pre-mordant dyeing.

Social implications
Wool dyeing processes that use one-bath dyeing consume less water and produce fewer effluents. As a result, this strategy conserves water and energy for a higher quality of life. The findings of this study, in general, aid environmental protection.

Originality/value
A novel one-bath process for dyeing wool with cochineal dye at heavy depths is introduced. RSM was used to optimize the procedure and determine effective parameters on the color strength of dyed wools. Using extracted cochineal dye and aluminum sulfate in a simultaneous dyeing technique, good color fastness qualities on wool fibers were achieved.
A wavelength calibration method for photoelastic-modulated Fourier transform spectrometers
Authors: Zhang Minjuan , Jing Ning , Liu Zhen , Li Chunyang , Zhang Ning 
Published: June 2022

Purpose
An interferogram is produced by modulating the difference between the extraordinary refractive index and the ordinary refractive index for photoelastic crystals in photoelastic-modulated Fourier transform spectrometers (PEM-FTs). Due to the influence of the refractive index dispersion characteristics on the maximum optical path difference of the interferogram, it is necessary to study wavelength calibration methods.

Design/methodology/approach
A wavelength calibration method for PEM-FTs was proposed based on the modulation principle of the photoelastic-modulated interferometer and the relationship between the maximum optical path difference and the refractive index difference. A 632.8 nm narrow-pulse laser was used as a reference source to measure the maximum optical path difference () of the interferogram, and the parameter was used to calculate the discrete frequency points in the frequency domain. To account for the influence of refractive index dispersion on the maximum optical path difference, the refractive index curve for the photoelastic crystal was used to adjust the discrete frequency coordinates.

Findings
The error in the reconstructed spectral frequency coordinates clearly decreased. The maximum relative error was 2.5%. A good solar absorption spectrum was obtained with a PEM-FT experimental platform and the wavelength calibration method.

Originality/value
The interferogram is produced by adjusting the difference between extraordinary refractive index and ordinary refractive index for the photoelastic crystal in the PEM-FTs. Given the wavelength dependence on the refractive indices, in view of the modulation principle of the photoelastic modulated interferometer, the relationship between the maximum optical path difference and the refractive index difference, the variation law of the refractive index of the photoelastic crystal and the process of spectral reconstruction is presented in this paper.
Nutritional intake and foodservice satisfaction of adults receiving specialist inpatient mental health services
Authors: Porter Judi , Collins Jorja 
Published: June 2022

AbstractAimMeeting the nutritional needs and foodservice expectations of hospital inpatients is challenging. This study aimed to determine whether adults receiving specialist inpatient mental health services meet their energy and protein requirements and are satisfied with the foodservice.MethodsAn observational study of adults admitted to three specialist inpatient mental health services within a large health service. Energy and protein intake were determined over 24 h via observation, and nutritional requirements were estimated using standard procedures. Validated questionnaires were used to assess satisfaction with the lunch meal, elements of the foodservice system, and overall foodservice satisfaction.ResultsAmong 74 participants, the median (IQR) energy intake (6954 [5111–10 250]kJ/day) was less than estimated requirements (8607 [7319–9951]kJ/day), whilst protein intake (85 [62–120]g/day) exceeded requirements (59 [46–70]g/day). Food from external sources was consumed by 50% of participants. Satisfaction surveys found vegetables were rated more poorly than the meat or carbohydrate portion of the meal, food quality was rated lowest compared with meal service, staffing and physical environment. The majority of participants (89%) rated their last meal as average, with the remainder (11%) rating it as poor.ConclusionThere are opportunities to improve the meal and foodservice experience for this patient group to meet their nutritional requirements and expectations. Investment in quality food and menus that are appropriate for the demographics, exploration of the most appropriate foodservice system, and adequate dietetic resourcing are needed to improve nutrition care within specialist inpatient mental health services.
