Published: July 2020

Objectives

Identifying causal biomarkers of rheumatoid arthritis (RA) to improve treatment and monitor disease progression remains a critical but elusive goal. To search for putatively causal protein biomarkers of RA, we designed an integrative genomic strategy utilizing Mendelian randomization (MR), which allows for causal inference between an exposure and an outcome by incorporating genetic variants associated with an exposure (circulating protein level) and inferring its effect on the outcome (rheumatoid arthritis).

Methods

We utilized genetic variants associated with 71 cardiovascular disease-related proteins measured in nearly 7000 Framingham Heart Study participants in conjunction with variants associated with RA in a genome-wide association study (GWAS) from the UK Medical Research Council Integrative Epidemiology Unit (19,234 cases, 61,565 controls) to identify putatively causal proteins for RA. In addition, we applied MR to study circulating rheumatoid factor (RF) levels using GWAS of RF from the UK Biobank (n=30,565) as the outcome.

Results

We identified the soluble receptor for advanced glycation end products (sRAGE), a critical inflammatory pathway protein, as putatively causal and protective for both RA (odds ratio per 1 standard deviation increment in inverse-rank normalized sRAGE level=0.482; 95% confidence interval 0.374-0.622; p=1.85×10−08) and RF levels (β [change in RF level per sRAGE increment]=-1.280; SE=0.434; p=0.003).

Conclusions

By integrating GWAS of 71 cardiovascular disease-related proteins, RA, and RF, we identified sRAGE as a putatively causal protein protective for both RA ad RF levels. These results highlight the AGER/RAGE axis as a promising new target for RA treatment.

Since the global withdrawal of Sabin 2 oral poliovirus vaccine (OPV) from routine immunization, the Global Polio Eradication Initiative (GPEI) has reported multiple circulating vaccine-derived poliovirus type 2 (cVDPV2) outbreaks. cVDPV2 outbreaks are controlled with mass Sabin 2 OPV vaccination campaigns, which carry a small but serious risk of seeding future cVDPV2 outbreaks. Accurate forecasting models are essential for quantifying current and future cVDPV2 outbreak risk following Sabin 2 OPV campaigns, but it is unclear whether household community structure influences vaccine virus transmission or is relevant for assessing cVDPV2 outbreak risk. Here, we developed an agent-based model of Sabin 2 vaccine transmission to assess the role of household community structure on vaccine virus transmission following a mass OPV campaign performed in Matlab, Bangladesh. Household community structure strongly limits vaccine virus transmission to local community members and ignoring it overestimates outbreak risk in terms of emergence probability, duration, and epidemic size.
DrosophilaUSP22/non-stop regulates the Hippo pathway to polarise the actin cytoskeleton during collective border cell migration
Authors: Badmos Hammed , Cobbe Neville , Campbell Amy , Bennett Daimark
Published: July 2020

Polarisation of the actin cytoskeleton is vital for the collective migration of cellsin vivo. During invasive border cell migration inDrosophila, actin polarisation is directly controlled by Hippo pathway components, which reside at contacts between border cells in the cluster. Here we identify, in a genetic screen for deubiquitinating enzymes involved in border cell migration, an essential role for non-stop/USP22 in the expression of Hippo pathway componentsexpandedandmerlin; loss ofnon-stopfunction consequently leads to a redistribution of F-actin and the polarity determinant Crumbs, loss of polarised actin protrusions and premature tumbling of the border cell cluster. Non-stop is a component of the Spt-Ada-Gcn5-acetyltransferase (SAGA) transcriptional coactivator complex, but SAGA’s histone acetyltransferase module, which does not bind toexpandedormerlin, is dispensable for migration. Taken together, our results uncover novel roles for SAGA-independent non-stop/USP22 in Hippo-mediated collective cell migration, which may help guide studies in other systems where USP22 is necessary for cell motility and invasion.

Published: July 2020

AMPK is a conservative energy sensor that plays roles in diverse biologic processes via direct phosphorylation on various substrates. Emerging studies have demonstrated the regulatory roles of AMPK in DNA repair, but the underlying mechanisms remain to be fully understood. Herein, using mass spectrometry-based proteomic technologies, we systematically investigate the regulatory network of AMPK in DNA damage response. Our system-wide phosphoproteome study uncovers a variety of newly-identified potential substrates involved in diverse biologic processes, whereas our system-wide histone modification analysis reveals a linkage between AMPK and histone acetylation. Together with these findings, we discover that AMPK promotes apoptosis by phosphorylating ASPP2 in irradiation-dependent way and regulates histone acetylation by phosphorylating HDAC9 in irradiation-independent way. Besides, we reveal that disturbing the histone acetylation by the bromodomain BRD4 inhibitor JQ-1 enhanced the sensitivity of AMPK-deficient cells to irradiation. Therefore, our studies provided a source to study the phosphorylation and histone acetylation underlying the regulatory network of AMPK, which could be beneficial to understand the exact role of AMPK in DNA damage response.

Nonsense-mediated decay (NMD) is a translation-dependent RNA quality control mechanism that occurs in the cytoplasm. However, it is unknown how NMD regulates the stability of RNAs translated at the endoplasmic reticulum (ER). Here, we identify a localized NMD pathway dedicated to ER-translated mRNAs. We previously identified NBAS, a component of the Syntaxin 18 complex involved in Golgi-to-ER trafficking, as a novel NMD factor. Furthermore, we show that NBAS fulfills an independent function in NMD. This ER–NMD pathway requires the interaction of NBAS with the core NMD factor UPF1, which is partially localized at the ER in the proximity of the translocon. NBAS and UPF1 coregulate the stability of ER-associated transcripts, in particular those associated with the cellular stress response. We propose a model where NBAS recruits UPF1 to the membrane of the ER and activates an ER-dedicated NMD pathway, thus providing an ER-protective function by ensuring quality control of ER-translated mRNAs.

The circadian clock is encoded by a negative transcriptional feedback loop that coordinates physiology and behavior through molecular programs that remain incompletely understood. Here, we reveal rhythmic genome-wide alternative splicing (AS) of pre-mRNAs encoding regulators of peptidergic secretion within pancreatic β cells that are perturbed in Clock−/− and Bmal1−/− β-cell lines. We show that the RNA-binding protein THRAP3 (thyroid hormone receptor-associated protein 3) regulates circadian clock-dependent AS by binding to exons at coding sequences flanking exons that are more frequently skipped in clock mutant β cells, including transcripts encoding Cask (calcium/calmodulin-dependent serine protein kinase) and Madd (MAP kinase-activating death domain). Depletion of THRAP3 restores expression of the long isoforms of Cask and Madd, and mimicking exon skipping in these transcripts through antisense oligonucleotide delivery in wild-type islets reduces glucose-stimulated insulin secretion. Finally, we identify shared networks of alternatively spliced exocytic genes from islets of rodent models of diet-induced obesity that significantly overlap with clock mutants. Our results establish a role for pre-mRNA alternative splicing in β-cell function across the sleep/wake cycle.

Published: July 2020

Studies of microbiomes are booming, along with the diversity of computational approaches to make sense out of the sequencing data and the volumes of accumulated microbial genotypes. A swift evaluation of newly published methods and their improvements against established tools is necessary to reduce the time between the methods' release and their adoption in microbiome analyses. The LEMMI platform offers a novel approach for benchmarking software dedicated to metagenome composition assessments based on read classification. It enables the integration of newly published methods in an independent and centralized benchmark designed to be continuously open to new submissions. This allows developers to be proactive regarding comparative evaluations and guarantees that any promising methods can be assessed side by side with established tools quickly after their release. Moreover, LEMMI enforces an effective distribution through software containers to ensure long-term availability of all methods. Here, we detail the LEMMI workflow and discuss the performances of some previously unevaluated tools. We see this platform eventually as a community-driven effort in which method developers can showcase novel approaches and get unbiased benchmarks for publications, and users can make informed choices and obtain standardized and easy-to-use tools.

DNA-associated proteins (DAPs) classically regulate gene expression by binding to regulatory loci such as enhancers or promoters. As expanding catalogs of genome-wide DAP binding maps reveal thousands of loci that, unlike the majority of conventional enhancers and promoters, associate with dozens of different DAPs with apparently little regard for motif preference, an understanding of DAP association and coordination at such regulatory loci is essential to deciphering how these regions contribute to normal development and disease. In this study, we aggregated publicly available ChIP-seq data from 469 human DAPs assayed in three cell lines and integrated these data with an orthogonal data set of 352 nonredundant, in vitro–derived motifs mapped to the genome within DNase I hypersensitivity footprints to characterize regions with high numbers of DAP associations. We establish a generalizable definition for high occupancy target (HOT) loci and identify putative driver DAP motifs in HepG2 cells, including HNF4A, SP1, SP5, and ETV4, that are highly prevalent and show sequence conservation at HOT loci. The number of different DAPs associated with an element is positively associated with evidence of regulatory activity, and by systematically mutating 245 HOT loci with a massively parallel mutagenesis assay, we localized regulatory activity to a central core region that depends on the motif sequences of our previously nominated driver DAPs. In sum, this work leverages the increasingly large number of DAP motif and ChIP-seq data publicly available to explore how DAP associations contribute to genome-wide transcriptional regulation.
Efficient food service chain management considering substitute products
Authors: Ko Young Dae , Song Byung Duk , Park Kyungsu
Published: July 2020

Purpose

This study investigates the pricing and inventory control decisions of a company that owns a coffeehouse chain providing drip coffee and a coffee manufacturing factory producing ready-to-drink (RTD) coffee. To determine a way to maximize profit, optimal pricing and inventory control strategies are studied for both the RTD coffee as well as the coffeehouse chain network.

Design/methodology/approach

It is assumed that the company sells only drip coffee through its coffeehouse chain and would like to launch RTD coffee via other channels such as convenience stores, supermarkets and so on to maximize its total profit. A mathematical model–based optimization is adopted to address the decision-making for the given problem situation, where the demand for both drip and RTD coffee are dependent on the values of decision variables. To solve the proposed mathematical model, particle swarm optimization (PSO) is applied due to nonlinearity of the developed model.

Findings

It is confirmed that a company can earn more profit by launching RTD coffee, even though the profit from drip coffee would reduce. In addition, the scenario analysis shows that by launching RTD coffee under various conditions, the total profits would also improve.

Originality/value

The value of this study is the proposed basic framework for the industry. In addition to the modeling framework and cost structure, realistic cost figures and technical details can be considered when applying the model to a practical setting.

Published: July 2020

Purpose

This study examines the effect that environmental, social and governance (ESG) disclosure generates on the cost of equity capital in the food and beverage (F&B) sector.

Design/methodology/approach

This study analyses a sample of 171 international listed firms pertaining to the F&B sector and headquartered in North America, Western Europe and Asia Pacific (developed), forming an unbalanced panel of 1,316 observations, spanning the period 2010–2019. We run a fixed-effects panel regression model to test the relationship between ESG disclosure and the cost of equity capital.

Findings

Our empirical outcomes suggest a significant negative relationship between ESG disclosure and the cost of equity capital. We find support for the notion that increased levels of ESG disclosure are linked to an improved access to financial resources for firms.

Originality/value

This is the first study that analyses the impact of ESG disclosure on the cost of equity capital in the F&B sector, taking existing literature a step further into more detailed and specific aspects of the relationship of focus.

Tolerating errors in hospitality organizations: relationships with learning behavior, error reporting and service recovery performance
Authors: Wang Xingyu , Guchait Priyanko , Paşamehmetoğlu Aysin
Published: July 2020

Purpose

Hospitality work setting is error-prone, rendering error handling critical for effective organizational operation and quality of service delivery. An organization’s attitude toward errors can be traced back to one fundamental question: should errors be tolerated/accepted or not? This study aims to examine the relationships between error tolerance and hospitality employees’ three critical work behaviors, namely, learning behavior, error reporting and service recovery performance. Psychological safety and self-efficacy are hypothesized to be the underlying attitudinal mechanisms that link error tolerance with these behavioral outcomes.

Design/methodology/approach

This study relied on a survey methodology, collecting data from 304 frontline restaurant employees in Turkey and their direct supervisors. SPSS 25.0 and Amos 25.0 were used for analysis.

Findings

The results revealed that error tolerance had direct positive relationships with employees’ psychological safety and self-efficacy, both of which had positive impacts on learning behavior and error reporting. In addition, learning behavior positively influenced employees’ service recovery performance, as rated by the employees’ supervisors.

Originality/value

This study identifies error tolerance as an organizational distal factor that influences employees’ learning behavior, error reporting and service recovery performance; and identifies self-efficacy and psychological safety as mediators of the relationship between error tolerance and behavioral outcomes. The findings help clarify the longstanding debate over the relationship between an organization’s attitude toward errors and its employees’ learning behavior. The findings also shed light on the advantages of tolerating error occurrence for organizations, which is especially important as most hospitality organizations pursue perfection with aversive attitudes toward errors.
Meta measurement of intelligence with crowd network
Authors: Yang Zheming , Ji Wen
Published: July 2020

Purpose

The multiple factors of intelligence measurement are critical in intelligent science. The intelligence measurement is typically built as a model based on multiple factors. The different agent is generally difficult to measure because of the uncertainty between multiple factors. The purpose of this paper is to solve the problem of uncertainty between multiple factors and propose an effective method for universal intelligence measurement for the different agents.

Design/methodology/approach

In this paper, the authors propose a universal intelligence measurement method based on meta-analysis for crowd network. First, the authors get study data through keywords in the database and delete the low-quality data. Second, they compute the effect value by odds ratio, relative risk and risk difference. Then, they test the homogeneity by Q-test and analyze the bias by funnel plots. Third, they select the fixed effect and random effect as a statistical model. Finally, through the meta-analysis of time, complexity and reward, the weight of each factor in the intelligence measurement is obtained and then the meta measurement model is constructed.

Findings

This paper studies the relationship among time, complexity and reward through meta-analysis and effectively combines the measurement of heterogeneous agents such as human, machine, enterprise, government and institution.

Originality/value

This paper provides a universal intelligence measurement model for crowd network. And it can provide a theoretical basis for the research of crowd science.
Evaluation on the pressure distribution and body-shaping effectivity of graduated compression shaping pants
Authors: Li Haixia , Wang Yongrong , Chen Zhian
Published: July 2020

Purpose

Graduated compression shaping pants (GCSPs) are shapewears sharing the same action mechanisms as medical compression stockings (MCSs), setting four stages of pressure on lower limbs that gradually decreasing from the ankle to the thigh root. They are claimed to be able to not only shaping bodies but also promoting blood circulation in legs. However, there are few studies on whether GCSPs perform the advertised functions and how effective GCSPs could be. The purpose of this paper is to explore and evaluate the pressure distribution and body-shaping effectivity of GCSPs.

Design/methodology/approach

The authors first select two graduated compression shaping pants (GCSPs-A, GCSPs-B) and a pair of professional shaping pants as the Controls. Then objective pressure test and 3D body scanning test are conducted. Finally, the pressure distribution and body-shaping effectivity are demonstrated by ORIGIN and MATLAB, compared with controls.

Findings

GCSPs-A perform significant body-shaping effectivity at the calf, thigh and thigh root, which are less effective than the Controls. The body-shaping effectivity of GCSPs-B is predicted weaker than GCSPs-A at the calf and thigh, while better at the thigh root. Both GCSPs-A and GCSPs-B show gradual pressure, which could be classified into Class I or II of MCSs. Comprehensively, GCSPs-A are superior than GCSPs-B.

Originality/value

In this paper, authors evaluate the pressure distribution and body-shaping effectivity of GCSPs, which could provide guidance for enterprises to further optimize and produce GCSPs, performing better functions that meet consumers' needs better.
Types of banking institutions and economic growth
Authors: Elmawazini Khaled , Khiyar Khiyar Abdullah , Aydilek Asiye
Published: July 2020

Purpose

This paper aims to compare the effects of Islamic and commercial banks on economic growth among the Gulf Cooperation Council (GCC) countries during 2001–2009 (before and during the financial crisis) and 2010–2017 (after the financial crisis).

Design/methodology/approach

The authors use a cross-sectionally correlated and timewise autoregressive (CCTA) model. The authors also extend the theoretical endogenous growth model developed by Pagano (1993) by introducing the developments in Islamic and commercial financial markets.

Findings

The authors find that Islamic banks fueled economic growth more than conventional banks before and after the financial crisis. The authors conclude that finance is a major determinant of economic growth, but finance does not follow economic growth. The results show that the ethical principles of Islamic finance can positively affect economic growth.

Originality/value

The authors contribute to the empirical literature first by examining feedback causality and cointegration between the banking sector and economic growth by examining the impact of the interaction between the banking sector and rule of law on economic growth in the GCC countries instead of a single country, second by providing both of the theoretical and empirical analysis and third by distinguishing between Islamic and conventional banks.
Information confusion and intention to stop using social networking site: a moderated mediation study of psychological distress and perceived novelty
Authors: Dang Van Thac
Published: July 2020

Purpose

People are living in a very rich and diversified information world. However, they are facing an explosion of information on social networking site (SNS) bombarding them every day. People get confused when they expose to similar, overloaded, ambiguous and misleading information. Unfortunately, the effect of information confusion on users' psychological outcome and behavioral intention has been absent in prior literature. Thus, this study investigates the relationship between information confusion and users' intention to stop using SNS with a moderated mediation effect of psychological distress and perceived novelty.

Design/methodology/approach

This study uses questionnaire survey to collect a sample data of 380 Facebook users in Vietnam. Structural equation modeling is used to test hypotheses in this study.

Findings

Empirical results show that information confusion has a positive influence on stop using intention. Furthermore, psychological distress is found to have a mediating effect in the link between information confusion and stop using intention. In addition, perceived novelty moderates the relationship between psychological distress and stop using intention. Perceived novelty also moderates the indirect effect of information confusion on stop using intention through psychological distress.

Originality/value

The influence of information confusion on users' psychological outcomes and behavioral intention has not been determined in prior literature. This study is one of the first studies that provide empirical evidence to clarify the relationship between information confusion and users' intention to stop using SNS. Furthermore, this study helps to clarify the mediating and moderating mechanism of psychological distress and perceived novelty in this relationship. By investigating the issue of information confusion and its impact on users in SNS environment, this study provides implications for researchers and practitioners regarding management and development of SNS.
Knowledge management, customer relationship management and innovation capabilities
Authors: Migdadi Mahmoud M.
Published: July 2020

Purpose

The purpose of this study is to introduce a unified framework, which integrates knowledge management (KM) (knowledge acquisition, diffusion and application, knowledge from a customer, knowledge about customers and knowledge for customers), customer relationship management (CRM) success (information sharing, customer involvement, long-term partnership, joint-problem solving and technology-based CRM) and innovation capabilities (ICs) (product innovation, process innovation, marketing innovation, service innovation and administrative innovation). Then empirically test the effect of KM on CRM success, the effect of CRM success on IC and the impact of KM on IC through the mediator.

Design/methodology/approach

Statistical techniques used included confirmatory factor analysis and structural equation modeling using AMOS to test the hypotheses.

Findings

The results show that KM influences CRM success, which, in turn, affects IC and KM impacts IC through CRM success.

Research limitations/implications

The study uses data provided by only one key informant per firm, which could involve a degree of subjectivity. This study is cross-sectional, which prevents us from examining the evolution over time of the phenomenon under investigation.

Practical implications

If organizations fully comprehend KM and CRM, they would be able to implement them successfully, creating value for their companies and fostering IC.

Originality/value

The existing research on CRM and KM is primarily conceptual and descriptive in nature and empirical research confirming the real impact of KM processes when developing a CRM innovation is lacking. The relationship between ICs and CRM has not been adequately studied. Hence, this study introduces a conceptual framework, which integrates KM, CRM, ICs and empirically tests the relationships among them.
The self-care practices of school principals
Authors: Ray Joshua , Pijanowski John , Lasater Kara
Published: July 2020

Purpose

The purpose of this study was to explore the well-being of school principals and the job-embedded demands responsible for challenging their adoption of healthy self-care practices.

Design/methodology/approach

Drawing upon a multidisciplinary theoretical framework that included contributions from the fields of neurobiology and psychology, three tiers of self-care needs were established to inform the study: basic physiological needs such as sleep, hydration, and nutrition; active self-care practices such as exercise, relaxation, and stress relief; and higher order needs such as belongingness and love addressed through work-life balance, volunteerism, and relational belonging. A 45-question survey containing Likert scale items and open-ended questions was returned from 473 practicing building administrators (a 24.4% response rate).

Findings

Findings from this study, compared to estimates from the literature, indicate that school leaders work longer hours, are more sleep deprived, more dehydrated, have poorer diet practices, exercise less regularly, and spend less time with their friends and family than the general population. Administrators struggled to find ways within their control to improve their self-care behavior and offered suggestions regarding how the structure of the job itself might be changed to facilitate improving the health of school leaders.

Originality/value

This work offers insight into the current well-being of school principals, and by better understanding administrators’ self-care practices, this study can inform the field in developing supports, practices, and expectations, which promote the health and well-being of building-level leaders. Unhealthy self-care practices may influence their effectiveness, happiness, and possibly their longevity within the profession. Data collected through this study informed ideas about policies and procedures that could promote greater opportunities for healthier, more effective leaders within schools.
The impact of teacher entrepreneurial behaviour: a timely investigation of an emerging phenomenon
Authors: Ho Chun Sing Maxwell , Lu Jiafang , Bryant Darren A.
Published: July 2020

Purpose

This study aims to understand of the role that teacher entrepreneurial behavior plays in developing teacher professional capital. The extant concepts around school leadership mostly encompass the transformative and instructional roles of school leaders in managing, mobilizing and supporting teachers for student achievement. However, school leadership has not focused strongly on promoting innovation and risk-taking for schools in a knowledge economy. As a timely promising response to the increasingly demanding and competitive school context, teacher entrepreneurial behaviour (TEB), which emphasizes teachers' willingness to take risks and be daring, has started to gain recognition in the school leadership literature, yet a nuanced understanding of TEB's potential impacts on schools is lacking.

Design/methodology/approach

Based on a combined consideration of institutionalized recognition and expert judgement, this study identified three innovative entrepreneurial teachers/teacher groups that had won the most competitive teaching award in Hong Kong. Employing a multiple-site case study design, this study conducted semi-structured interviews with 23 informants and collected supplementary school documents and records.

Findings

This study found that TEB enables the implementation of innovation and promotes cross-subject alignment. It cultivates trusting and coherent relationships among teachers. Teachers with TEB scaled up innovation among other teachers. Furthermore, entrepreneurial teachers enhance school attractiveness by creating competitive advantages.

Originality/value

This analysis showed that TEB enables formal and informal school leaders to bring forth critical school outcomes. This study elaborates how TEB enhances teachers' professional capital through building trusting and coherent relationships. It also adds to the research on school innovation by demonstrating that TEB fosters teachers' capacity for bottom-up innovation in the community.
Bricolage as a path towards organizational innovativeness in times of market and technological turbulence
Authors: Santos Leandro Lima dos , Borini Felipe Mendes , Pereira Rafael Morais
Published: July 2020

Purpose

Companies need guidance on how to operate in turbulent environments to improve their innovative performance. However, few studies have been done specifically about how to market and technological turbulence affects the innovative performance in emerging markets. This paper aims to propose model with market turbulence, technological turbulence and firm’s bricolage behavior as antecedents of organizational innovativeness.

Design/methodology/approach

Two conceptualizations of the role of environmental turbulence are examined as follows: that market turbulence and technological turbulence are established as direct antecedents to organizational innovativeness performance; and the model has a mediating effect through the bricolage behavior. In this sense, the strengths of the paths differ depending on the presence of bricolage. Data were collected from 215 firms operating in Brazil, analyzed using the partial least squares (PLS)-structural equation modeling (SEM) technique as a quantitative method to test the hypotheses.

Findings

The results indicate that the mediating effect evidenced by the bricolage behavior was supported. In other words, the path from market and technological turbulence to organizational innovativeness is significantly better when permeated by bricolage behavior in the organization.

Research limitations/implications

It can be suggested to conduct similar research with larger sample size and applying control variables such as the size of the company, as smaller companies have less access to resources and maybe the engagement in bricolage can be even more substantial for them to keep innovating and to remain competitive in times of turbulence.

Practical implications

Some managerial recommendations and implications are provided. Managers should recognize the possible improvements in the organizational innovativeness development by actively including the bricolage behavior among their companies’ activities.

Originality/value

The theoretical contribution to the academic knowledge lies in corroborating with previous studies, which pointed out that bricolage has an influence on a firm’s innovativeness and some studies, which address perspectives in the organizational learning field.
Will the customers be happy? Identifying unsatisfied customers from service encounter data
Authors: Baier Lucas , Kühl Niklas , Schüritz Ronny , Satzger Gerhard
Published: July 2020

Purpose

While the understanding of customer satisfaction is a key success factor for service enterprises, existing elicitation approaches suffer from several drawbacks such as high manual effort or delayed availability. However, the rise of analytical methods allows for the automatic and instant analysis of encounter data captured during service delivery in order to identify unsatisfied customers.

Design/methodology/approach

Based on encounter data of 1,584 IT incidents in a real-world service use case, supervised machine learning models to predict unsatisfied customers are trained and evaluated.

Findings

We show that the identification of unsatisfied customers from encounter data is well feasible: via a logistic regression approach, we predict dissatisfied customers already with decent accuracy—a substantial improvement to the current situation of “flying blind”. In addition, we are able to quantify the impacts of key service elements on customer satisfaction.

Research limitations/implications

The possibility to understand the relationship between encounter data and customer satisfaction will offer ample opportunities to evaluate and expand existing service management theories.

Practical implications

Identifying dissatisfied customers from encounter data adds a valuable methodology to customer service management. Detecting unsatisfied customers already during the service encounter enables service providers to immediately address service failures, start recovery actions early and, thus, reduce customer attrition. In addition, providers will gain a deeper understanding of the relevant drivers of customer satisfaction informing future new service development.

Originality/value

This article proposes an extendable data-based approach to predict customer satisfaction in an automated, timely and cost-effective way. With increasing data availability, such AI-based approaches will spread quickly and unlock potential to gain important insights for service management.
The IPSASB's recent strategies: opportunities for academics and standard-setters
Authors: Jensen Gwenda
Published: July 2020

Purpose

The purpose of this article is to contribute to an ongoing dialogue between practitioners and academics. This article describes the International Public Sector Accounting Standards Board (IPSASB) recent strategies and highlights the IPSASB's increasing outreach to academics.

Design/methodology/approach

This is a practitioner's viewpoint which reflects the IPSASB's publicly available documents, and the opinions of a practitioner directly involved in the IPSASB's work and International Public Sector Accounting Standards (IPSAS) development.

Findings

The findings are that the IPSASB has increased its outreach to academics and now academics have more opportunities to engage with the IPSASB and IPSAS developments. The IPSASB's strategy has remained relatively constant over time, focusing on IPSAS to address public sector-specific issues, alignment with the International Financial Reporting Standards (IFRS) and reduction of differences between IPSAS and Government Finance Statistics (GFS) reporting guidelines.

Research limitations/implications

The limitations of this article (which are also its strength in terms of fitness for purpose) are that as a practitioner's viewpoint it provides a brief overview and personal judgments, rather than an empirical analysis of developments applying a theoretical framework.

Practical implications

The practical implications were IPSASB's increased outreach to the research community providing opportunities for academics to have increased input into IPSAS development, with likely benefits to researchers and the IPSASB.

Social implications

Practitioners’ engagement with academics supports increased understanding of the respective views leading to better outcomes for practitioners and academics working in the area of public sector financial reporting and its regulation.

Originality/value

This article is the first to (a) describe the IPSASB's increasing outreach to academics during 2019–2020 and (b) compare the IPSASB's strategies for the period of 2019–2023, with its strategies since the beginning of IPSAS developments in 1996–1997.
Political competition as a motivation for earnings management close to zero: the case of Portuguese municipalities
Authors: Ferreira Augusta , Carvalho João , Pinho Fátima
Published: July 2020

Purpose

The main purpose of this paper is to evaluate if, motivated by political competition, municipalities engage in earnings management practices through discretionary accruals.

Design/methodology/approach

Quantitative methodology.

Findings

Results indicate that, in those municipalities where political competition is greatest, there is a greater tendency to report positive net earnings close to zero. This study also indicates that for such purpose, discretionary accruals are used.

Originality/value

The purpose of this paper is to respond to the lack of information in the area of earnings management in the public sector, to be able to evaluate responsibility, performance and efficiency regarding the allocation of public resources and the degree of satisfaction of citizens/voters' needs-accountability.
A conceptual virtual research environment model for the management of research data, a South African perspective
Authors: Van Wyk Johann , Bothma Theo , Holmner Marlene
Published: July 2020

Purpose

The purpose of this article is to give an overview of the development of a Virtual Research Environment (VRE) conceptual model for the management of research data at a South African university.

Design/methodology/approach

The research design of this article consists of empirical and non-empirical research. The non-empirical part consists of a critical literature review to synthesise the strengths, weaknesses (limitations) and omissions of identified VRE models as found in literature to develop a conceptual VRE model. As part of the critical literature review concepts were clarified and possible applications of VREs in research lifecycles and research data lifecycles were explored. The empirical part focused on the practical application of this model. This part of the article follows an interpretivist paradigm, and a qualitative research approach, using case studies as inquiry method. Case studies with a positivist perspective were selected through purposive sampling, and inferences were drawn from the sample to design and test a conceptual VRE model, and to investigate the management of research data through a VRE. Investigation was done through a process of participatory action research (PAR) and included semi-structured interviews and participant observation data collection techniques. Evaluation of findings was done through formative and summative evaluation.

Findings

The article presents a VRE conceptual model, with identified generic component layers and components that could potentially be applied and used in different research settings/disciplines. The article also reveals the role that VREs play in the successful management of research data throughout the research lifecycle. Guidelines for setting up a conceptual VRE model are offered.

Practical implications

This article assisted in clarifying and validating the various components of a conceptual VRE model that could be used in different research settings and disciplines for research data management.

Originality/value

This article confirms/validates generic layers and components that would be needed in a VRE by synthesising these in a conceptual model in the context of a research lifecycle and presents guidelines for setting up a conceptual VRE model.
Financial well-being for a sustainable society: a road less travelled
Authors: Mahendru Mandeep
Published: July 2020

Purpose

Measurement of financial well-being has remained a challenge for the governments for a long time. This paper responds to this challenge by taking an integrative approach, whereby the previous conceptualizations of financial well-being are examined. Further, we propose a new conceptualization of financial well-being using the parameters of objective and subjective well-being.

Design/methodology/approach

We conduct a widespread review of the literature with regard to the linkage between financial literacy and financial capability.

Findings

Numerous studies report the pertinent role of behavioural economics in rational decision making. This paper understands the role of behavioural economics in regard to financial well-being.

Research limitations/implications

Empirical investigation in measuring the linkage between financial literacy and financial capability needs to be developed to achieve the goal of financial well-being.

Originality/value

This paper makes a noble contribution to the literature by proposing a new conceptualization of financial well-being spread over financial literacy, financial capability and psychological factors.
