Authors: Wei Fangfang , Zhang Guijie 
Published: June 2020

PurposeThis paper aims to present a longitudinal and visualizing study using scientometric approaches to depict the historical changes in the academic community, intellectual base and research hotspots within the business domain.Design/methodology/approachTwo mapping methods are used, namely, co-citation analysis and co-occurrence analysis. Both the co-citation analysis and co-occurrence analysis in this study are conducted using CiteSpace, a Java-based scientific visualization software.FindingsThis paper detects changes in academic communities in 24 business journals chosen by the University of Texas at Dallas as leading journals (UTD24) and identifies the research hotspots such as corporate governance, organizational research and capital research. Many authors and academic communities appear in two or even three periods, which indicates the lasting academic vitality of scholars in this field. This paper determines the evolution of scholars' research interests by identifying high-frequency keywords during the entire period.Originality/valueThis paper reveals a systematic and holistic picture of the developmental landscape of the business domain, which can provide a potential guide for future research. Furthermore, based on empirical data and knowledge visualization, the intellectual structure and evolution of the business domain can be identified more objectively.
A Clark-Wilson and ANSI role-based access control model
Authors: Tsegaye Tamir , Flowerday Stephen 
Published: June 2020

Purpose
An electronic health record (EHR) enables clinicians to access and share patient information electronically and has the ultimate goal of improving the delivery of healthcare. However, this can create security and privacy risks to patient information. This paper aims to present a model for securing the EHR based on role-based access control (RBAC), attribute-based access control (ABAC) and the Clark-Wilson model.

Design/methodology/approach
A systematic literature review was conducted which resulted in the collection of secondary data that was used as the content analysis sample. Using the MAXQDA software program, the secondary data was analysed quantitatively using content analysis, resulting in 2,856 tags, which informed the discussion. An expert review was conducted to evaluate the proposed model using an evaluation framework.

Findings
The study found that a combination of RBAC, ABAC and the Clark-Wilson model may be used to secure the EHR. While RBAC is applicable to healthcare, as roles are linked to an organisation’s structure, its lack of dynamic authorisation is addressed by ABAC. Additionally, key concepts of the Clark-Wilson model such as well-formed transactions, authentication, separation of duties and auditing can be used to secure the EHR.

Originality/value
Although previous studies have been based on a combination of RBAC and ABAC, this study also uses key concepts of the Clark-Wilson model for securing the EHR. Countries implementing the EHR can use the model proposed by this study to help secure the EHR while also providing EHR access in a medical emergency.
Retirees and motivation to work by the type of employment contract: impact of the Czech reform
Authors: Pertold Filip , Lakotova Lenka 
Published: June 2020

PurposeIn this paper, the authors analyse a 2010 legal reform in the Czech Republic, which allowed retirees to simultaneously receive regular pension benefits and to work on a permanent contract for a period longer than one year. Previously, concurrence of employment and receipt of retirement benefits were only allowed in conjunction with a temporary work contract with a maximum duration of one year.Design/methodology/approachThe authors employ the difference-in-differences method. The authors include only males in the analysis because it is not possible to identify the legal retirement age for women from available data. Men in the workforce 1–3 years prior to the statutory retirement age are in a control group, while men 1–3 years older are in a treatment group.FindingsThe authors show that the reform significantly increased the share of permanent contracts held by retirees (by 22.5–27.6 percentage points), though we do not find any aggregate short-term change in employment of retirees. Heterogeneity analysis shows a significant increase in the employment of retirees with only elementary school education (by 17.9 percentage points) and a significant decrease in the number of hours worked by retirees (by 2.5 h weekly for low-educated workers).Practical implicationsThe policy conclusion is that the regulation of employment contract does not affect aggregate employment, but may improve employment of low skilled workers.Originality/valueTo the authors’ best knowledge, there are no studies directly analysing motivation of retirees by types of employment contracts. The authors, thus, add to the literature that studies dealing with the general fixed-term versus permanent contracts (Engellandt and Riphahn, 2003) and motivation to work.
Adapting guided inquiry learning worksheets for emergency remote learning
Authors: Howley Iris 
Published: June 2020

PurposeProcess-oriented guided inquiry learning (POGIL) is a series of learning activities building on student prior knowledge guiding them to construct their own understanding of new concepts in collaborative roles. This paper aims to illustrate how POGIL worksheets can be adapted for low bandwidth and low-computing environments to accommodate the largest swathe of learners in higher education, as was the case during the switch to emergency remote learning in 2020.Design/methodology/approachThe POGIL worksheets in this paper scaffold the discovery of new concepts while providing sample computer program output, guiding students to make predictions about the connection between program input and program output. Answers are provided to these questions after completion so that students may check their understanding or look to the answers as worked examples. These POGIL worksheets were used for the past two years in an in-person classroom situation with minimal computing resources, replacing 4/5 of a classroom lecture doing POGILs collaboratively. In the midst of emergency remote learning, these worksheets were adapted to complement asynchronous lecture videos, and also serve as lecture replacement as needed.FindingsThis paper discusses an approach to adapting POGIL worksheets for introduction to computer science for students who may not have the necessary digital tools (programing software, bandwidth for streaming video, etc.). While the context for this paper is computer science, POGIL has a deep history in chemistry education and other natural sciences, suggesting an approach that may be adapted for situations where hands-on laboratory experiments may not be possible.Originality/valueCS-POGIL has many materials available for computer science, but this paper discusses 23 new worksheets and how to adapt them to the novel situation of emergency remote teaching.
The role of psychological ownership in consumer happiness
Authors: Li Dan , Atkinson Lucy 
Published: June 2020

PurposeThis paper aims to examine the effect of psychological ownership on consumer happiness, which is mediated through basic psychological needs satisfaction.Design/methodology/approachData were collected by means of two online experiments. Study 1 tested and validated the hypotheses by examining post-consumption on a sample of 252 college students. Study 2 investigated the impact of psychological ownership in a pre-consumption scenario.FindingsThe results show that consumers feel happier when they have a higher psychological ownership over an item after consumption. Furthermore, consumers anticipate greater happiness from a product before consumption due to increased psychological ownership through customization. This effect is mediated by the satisfaction of basic psychological needs.Practical implicationsThe study will help marketers make their products or services as a better candidate for the target of psychological ownership through user experience design. Furthermore, the study encourages new business and marketing models, such as the sharing economy, that exploit the effect of psychological ownership.Originality/valueThe core contribution of this study is that it extends self-determination theory by distinguishing the effect of legal and psychological ownership on consumer happiness. It provides a better understanding of the psychological mechanism behind happiness.
Evaluating financial stress indicators: evidence from Indian data
Authors: Mundra Sruti , Bicchal Motilal 
Published: June 2020

Purpose
The purpose of this study is to assess alternative financial stress indicators for India in terms of tracing crisis events, mapping with the business cycle and the macroeconomic effect of stress indices.

Design/methodology/approach
The study constructs the composite indicator of systemic stress of Hollo, Kremer and Lo Duca (2012) for India using two different methods for computing time-varying cross-correlation matrix, namely, exponentially weighted moving average (EWMA) and dynamic conditional correlation-generalized autoregressive conditional heteroscedasticity (DCC-GARCH). The derived indices are evaluated with widely used, equal variance and principal component weighting indices in terms of tracing stress events, mapping with the business cycles and the macroeconomic effect. For this purpose, the study identifies various episodes of financial stress and uses the business cycle dates in the sample covering from January 2001 to October 2018.

Findings
The results suggest that stress indices based on EWMA and DCC-GARCH accurately identify the well-known stress periods and capture the recession dates and show an adverse effect on economic activity. Primarily, the DCC-GARCH-based stress index emerges as a better indicator of stress because it efficiently locates all the major-minor events, traces the build-up of stress and reverts to the normal level during stable times.

Practical implications
The DCC-GARCH-based stress index is a very useful indicator for policymakers in regularly monitoring India’s financial conditions and providing timely identification of systemic stress to avoid adverse repercussion effects of the financial crisis.

Originality/value
The 2007–2008 financial crisis and subsequent recurrent instability in the financial markets highlighted the requirement for an appropriate financial stress indicator for a timely assessment of the system-wide financial stress. To the authors’ knowledge, this is the first study that incorporates the systemic nature of financial stress in the construction of stress indices for India and provides a holistic evaluation of the financial stress from an emerging country’s perspective.
Identifying the influence of the Halal logo on Muslim consumers’ attitudes using fMRI technology
Authors: Al-Kwifi Osama Sam , Gelaidan Hamid Mahmood Hamid , Fetais Abdulla Hamad M. A. 
Published: June 2020

Purpose
Halal markets are rapidly growing in terms of market size and global coverage; therefore, there is a critical demand to have a deeper understanding of the consumption behavior of Muslim consumers. This study aims to explore the influence of using the Halal logo on Muslim consumers’ attitudes toward food products using the neuroscience technology of functional magnetic resonance imaging (fMRI).

Design/methodology/approach
The theory of planned behavior represents the foundation of this research, where consumer attitudes during an fMRI experiment were evaluated based on two different groups of images: images of just the Halal logo and images of meat labeled with the Halal logo. The study used the blocked design approach to track brain responses produced from displaying the two groups of images to study participants, where brain activity represents participants’ attitudes toward selecting the products.

Findings
There were no significant variations in brain activity when participants viewed Halal and non-Halal logos; in contrast, there were significant brain changes in the ventromedial prefrontal cortex region when meat images were labeled with Halal and non-Halal logos. This suggests that the Halal logo only has an influence on perception when it co-occurs with a product.

Research limitations/implications
Tracking Muslim consumption patterns is important for managers to be able to establish strategies to target Muslim consumers. This study uses a unique technique to study the behavioral attitude of a rapidly growing market segment, which can help marketing managers tailor their advertisement strategies to be more effective.

Originality/value
Previous research on the consumption of Halal products uses conventional approaches to study the influence of the Halal logo; however, to the best of the authors’ knowledge, this study is the first to explore the influence of the Halal logo on Muslim consumers’ attitudes using fMRI technology.
Combatting economic crimes in Nigeria through whistleblowing: a shift from policy to legal framework
Authors: Yakubu Sirajo , Dikwa Mohammed Kyari 
Published: June 2020

Purpose
The purpose of this paper is a holistic assessment of the impact of whistleblowing policy adopted by the Nigerian Government in fighting corruption and an evaluation of the whistleblowing and witness protection bill.

Design/methodology/approach
This paper is a critical analysis of the whistleblowing policy and the draft whistleblowing and witness protection bill. The paper combines both qualitative and quantitative methods. It is conducted through the study of the policy and the draft bill and the critical examination of the data released by the federal Ministry of Finance. Moreover, the personal experience of the authors in the civil service and in formulating and implementing the whistleblower policy account significantly.

Findings
The whistleblowing policy adopted by the Federal Republic of Nigeria is promising in controlling corruption and other economically motivated crimes. However, while efforts to give whistleblowing a legal backing will strengthen the fight against corruption in Nigeria, the National Assembly must subject the bill to rigorous debate to avoid having many lacunas in would be act.

Research limitations/implications
The use of whistleblowing in combatting corruption in Nigeria is still at its infancy. A policy document backs implementation of the policy – there is no legislation or case law to consider. Thus, analysis is based on the policy document, the bill, statistics from the FMF and personal experience of the authors.

Originality/value
There is no comprehensive study on the adoption of and efforts to give legal backing to, the whistleblowing policy adopted in Nigeria. This paper is of value to the Nigerian Government and the National Assembly considering the latest efforts to institutionalise whistleblowing in Nigeria.
Uncertainty avoidance culture, cash holdings and financial crisis
Authors: Tran Quoc Trung 
Published: June 2020

PurposeThis paper aims to investigate how the global financial crisis affects the relationship between uncertainty avoidance culture and corporate cash holdings.Design/methodology/approachThis study develops a research model in which cash holdings ratio is a function of post-crisis period dummy, Hofstede’s cultural dimension of uncertainty avoidance, their interactive term and control variables. The research sample includes 188,264 observations from 26,509 firms incorporated in 44 countries between 2003 and 2016.FindingsThis study finds that the effect of uncertainty avoidance culture on firm cash holdings is stronger in the post-crisis period from 2008 to 2016. This effect is stronger for financially constrained firms. In addition, the research findings show that uncertainty avoidance culture is more effective in cash–cash flow sensitivity over the post-crisis period.Originality/valuePrior studies show that uncertainty avoidance culture positively affects corporate cash reserves. However, the authors only examine the effect of uncertainty avoidance culture on cash holdings in a static environment. This paper investigates this effect under the impact of the global financial crisis – an exogenous shock.
Gender, race and power: an intersectional reading of “opting out”
Authors: Meléndez Georgianna , Özkazanç-Pan Banu 
Published: June 2020

PurposeThis paper considers the phenomenon of “opting out” from an intersectional lens, bringing in hitherto undertheorized dimensions of gender, race and power into the conversation related to why and how some women of color may make the “choice” to leave an organization.Design/methodology/approachThrough a single case study approach, our research elucidates how identity-connected experiences unconnected to work/life balance constraints and tensions caused one immigrant woman of color to leave the workplace. We expand upon the current use of intersectionality in management and organization studies by applying it as a lens to bring into consideration power relations in organizations and structural inequality as the context for understanding why and how some women of color may leave their places of employment.FindingsBased on our in-depth case study, we demonstrate that microaggressions, power relations, and structural inequities contribute to some women of color opting out.Originality/valueThis paper is of value to scholars interested in intersectionality framework applications.
Sensitivity of the tetraaminodiphenyl based pyroelectric sensor from visible to sub-THz range
Authors: Paulish Andrey G. , Gusachenko Anatoly V. , Morozov Alexander O. , Golyashov Vladimir A. , Dorozhkin Kirill V. , Suslyaev Valentin I. 
Published: June 2020

Purpose
The purpose of this paper is to study the spectral sensitivity characteristics of new pyroelectric sensor based on tetraaminodiphenyl film within the wavelength range of 0.4-10 µm and 300-3,000 µm.

Design/methodology/approach
Mylar film with the thickness of about 70 µm was used as the input window. The MDR-41 monochromator-based spectrometric complex and the quasi-optical spectrometer with the set of backward-wave oscillators were used for measurements of the pyrodetector spectral characteristics within the 0.4-10 µm and 300-3,000 µm ranges, respectively.

Findings
Mylar was found to have absorption lines within the range of 0.4-10 µm, which must be taken into account when broadband detectors developing. The noise equivalent power in the visible and infrared ranges was less than 6 × 10–10 W/Hz1/2, which is about five times lower than for analogue ones. In the sub-THz range, the pyrodetector sensitivity is 2-8 times higher than the Golay cell. The sensitivity of such pyrodetector weakly depends on the wavelength in the total measured range.

Practical implications
The pyroelectric sensor has good prospects for use in super wide spectral range, from ultraviolet to millimeter radiation, in spectrometers for scientific research, in industry for the operational control of THz radiation sources, as well as in security THz-systems.

Originality/value
The spectral sensitivity characteristics of the pyroelectric photosensor based on TADPh in the visible, infrared and terahertz ranges were measured. The prospects for the use of such sensors were determined.

Vacant yet invasible niches in forest community assembly
Authors: Gauzere Pierre , Morin Xavier , Violle Cyrille , Caspeta Ivanna , Ray Courtenay , Blonder Benjamin 
Published: June 2020

AbstractIt is controversial whether communities are saturated with species, or have vacant niches. The prevalence of vacant niches and the processes likely to promote their existence are poorly known.We used a process‐based forest gap‐model to simulate plant community dynamics in 11 sites along a climatic gradient across central Europe. We then used hypervolume analyses to study the existence of vacant niches (seen as empty volumes in the trait space of local species pools and communities), and we tested for the effect of abiotic (environmental filtering) and biotic (competition) processes on the functional hypervolumes along the climatic gradient. Last, we performed invasion simulations to assess the invasibility of detected vacant niches.Our results suggest that empty volumes in trait space are common, can arise from both abiotic and biotic processes and are more likely in cold climates. We also showed that most vacant niches are invasible.Synthesis. Our work supports the view that niche space is unsaturated, and that many viable ecological strategies are absent from these forest communities.A freePlain Language Summarycan be found within the Supporting Information of this article.
Warming alters plant phylogenetic and functional community structure
Authors: Zhu Juntao , Zhang Yangjian , Yang Xian , Chen Ning , Li Shaopeng , Wang Pandeng , Jiang Lin 
Published: June 2020

Abstract

Climate change is known to affect many facets of the Earth's ecosystems. However, little is known about its impacts on phylogenetic and functional properties of ecological communities.

Here we studied the responses of plant communities in an alpine grassland on the Tibetan Plateau to environmental warming across taxonomic, phylogenetic and functional levels in a 6‐year multiple‐level warming experiment.

While low‐level warming did not alter either plant species richness or phylogenetic/functional community structure, high‐level warming significantly decreased species richness. Higher level warming more strongly reduced soil moisture and caused stronger environmental filtering, consequently changing species composition and community structure. At the plant functional trait level, high‐level warming promoted species turnover through altering the effects of traits such as plant height on species extinction and SLA on species colonization. As a result, high‐, but not low‐level warming drove phylogenetic/functional community structure from overdispersion to randomness, by filtering out species that were functionally dissimilar and distantly related to the resident species.

Synthesis. Our study provides evidence that the responses of plant phylogenetic and functional community structure to low warming differ from those in the future scenarios of increasing temperature. Importantly, the extinction of species that was functionally dissimilar and distantly related to the resident species contributed to alterations in plant community structure under high warming. Our study underscores the need to incorporate the phylogenetic and functional perspectives to gain a more complete understanding of community responses to climate warming.
