Comparison of linear and non-linear GARCH models for forecasting volatility of select emerging countries
Authors: Sharma Sudhi , Aggarwal Vaibhav , Yadav Miklesh Prasad 
Published: December 2020

PurposeSeveral empirical studies have proven that emerging countries are attractive destinations for Foreign Institutional Investors (FIIs) because of high expected returns, weak market efficiency and high growth that make them attractive destination for diversification of funds. But higher expected returns come coupled with high risk arising from political and economic instability. This study aims to compare the linear (symmetric) and non-linear (asymmetric) Generalized Autoregressive Conditional Heteroscedasticity (GARCH) models in forecasting the volatility of top five major emerging countries among E7, that is, China, India, Indonesia, Brazil and Mexico.Design/methodology/approachThe volatility of financial markets of five major emerging countries has been empirically investigated for a period of two decades from January 2000 to December 2019 using univariate volatility models including GARCH 1, 1, Exponential Generalized Autoregressive Conditional Heteroscedasticity (E-GARCH 1, 1) and Threshold Generalized Autoregressive Conditional Heteroscedasticity (T-GARCH-1, 1) models. Further, to examine time-varying volatility, the distinctions of structural break have been captured in view of the global financial crisis of 2008. Thus, the period under the study has been segregated into pre- and post-crisis, that is, January 2001–December 2008 and January 2009–December 2019, respectively.FindingsThe findings indicate that GARCH (1, 1) model is superior to non-linear GARCH models for forecasting volatility because the effect of leverage is insignificant. China has been considered as most volatile, whereas India is volatile but positively skewed and Indonesia is the least volatile country. The results can help investors in better international diversification of their portfolio and identifying best suitable hedging opportunities.Practical implicationsThis study can help investors to construct a more risk-adjusted returns international portfolio. Further, it adds to the scant literature available on the inconclusive debate on the choice of linear versus non-linear models to forecast market volatility.Originality/valueEarlier studies related to univariate volatility models are mostly applications of the models. Only few studies have considered the robustness while applying the models. However, none of the studies to the best of the authors’ searches have considered these models for identifying the diversification opportunity among the emerging countries. Hence, this study is able to derive diversification and hedging opportunities by applying wide ranges of the statistical applications and models, that is, descriptive, correlations and univariate volatility models. It makes the study more rigorous and unique compared to the previous literature.
Social aspects of personal information organization
Authors: Oh Kyong Eun 
Published: December 2020

PurposeThe purpose of this paper is to examine how individuals' personal information organization reflects their social environments in order to understand social aspects of personal information organization.Design/methodology/approachBy using a cognitive sociological approach and based on the personal information organization process (PIOP) model (Oh, 2019), this study investigates the social aspects of personal information organization by analyzing the pre-diary interview, a diary, and two post-diary interviews conducted with each of the 18 information users in social science academic environments.FindingsSocial dimensions of personal information organization were found in differences between organizing academic and non-academic files, the way participants identified and made distinctions among files, common folders they created, and with the impact of participants' professional age on personal information organization. This study shows that information organization is a process of construction and that the participants' social foundations are reflected in the way they view and organize their files.Originality/valueThis study makes a unique contribution to the field by explaining the social aspects of personal information organization. The findings of this study deepen our knowledge of personal information organization by providing different ways to understand how and why people organize their files in certain ways, and by showing that this is not just individual behavior. In practice, this study provides insight into the design of applications and tools that support personal information management of people in specific social environments.
A coordinated control strategy for battery/supercapacitor hybrid energy storage system to eliminate unbalanced voltage in a standalone AC microgrid
Authors: Ren Yaxing , Rind Saqib Jamshed , Jiang Lin 
Published: December 2020

PurposeA standalone microgrid (MG) is able to use local renewable resources and reduce the loss in long distance transmission. But the single-phase device in a standalone MG can cause the voltage unbalance condition and additional power loss that reduces the cycle life of battery. This paper proposes an energy management strategy for the battery/supercapacitor (SC) hybrid energy storage system (HESS) to improve the transient performance of bus voltage under unbalanced load condition in a standalone AC microgrid (MG).Design/methodology/approachThe SC has high power density and much more cycling times than battery and thus to be controlled to absorb the transient and unbalanced active power as well as the reactive power under unbalanced condition. Under the proposed energy management design, the battery only needs to generate balanced power to balance the steady state power demand. The energy management strategy for battery/SC HESS in a standalone AC MG is validated in simulation study using PSCAD/EMTDC.FindingsThe results show that the energy management strategy of HESS maintains the bus voltage and eliminates the unbalance condition under single-phase load. In addition, with the SC to absorb the reactive power and unbalanced active power, the unnecessary power loss in battery is reduced with shown less accumulate depth of discharge and higher average efficiency.Originality/valueWith this technology, the service life of the HESS can be extended and the total cost can be reduced.

Authors: Awe Olajumoke A. , Church E. Mitchell 
Published: December 2020

PurposeThe purpose of this paper is to study project management performance measures by analyzing how training utility affects the relationships between mutual trust, social interaction and creativity as well as mutual trust, social interaction and flexibility in projects.Design/methodology/approachUsing training utility and organizational support theory, eight hypotheses were developed. Responses from 279 project management professionals in the USA were collected. The hypotheses were then tested using partial least squares (PLS) and regression with the PROCESS macro approach.FindingsThe results suggests that the communication environment indeed has an important role in fostering creative and flexible project managers. Additionally, the study shows that organizations can actively improve the influence of the communication environment on project management creativity through training efforts. Interestingly, these findings may not hold for project manager flexibility.Practical implicationsIn today's project management world, organizations need project managers who quickly adapt to changing project management scenarios. To do this, project managers need to be creative, generating new and novel ideas, as well as flexible when converting ideas into action. Organizations often possess large amounts of knowledge, and project managers rely on good communication practices to access this knowledge in response to the required changes in the project domain.Originality/valueThe study includes contributions to theory and empirical research in project management by analyzing the critical role training utility has on the firm communication environments and its outcomes. The study shows that organizations can take an active role by investing in resources to promote flexibility and creativity in projects.

Authors: Japutra Arnold , Molinillo Sebastian , Ekinci Yuksel 
Published: December 2020

PurposeThis study aims to investigate the role of destination brand stereotypes in predicting destination brand attachment (DBA).Design/methodology/approachUsing survey data from 612 Indonesian respondents, the conceptual framework is tested by applying structural equation modeling analysis.FindingsThe results show that the four components of destination branding contribute to DBA through brand stereotypes.Originality/valueBased on the stereotype content model, this study explores how two cognitive (i.e. brand awareness and perceived quality) and two affective (i.e. ideal self-congruence and enduring culture involvement) components build destination brand stereotypes, which in turn increase DBA.
Encountering misinformation online: antecedents of trust and distrust and their impact on the intensity of Facebook use
Authors: Cheng Yang , Chen Zifei Fay 
Published: December 2020

PurposeThis study focused on the impact of misinformation on social networking sites. Through theorizing and integrating literature from interdisciplinary fields such as information behavior, communication and relationship management, this study explored how misinformation on Facebook influences users' trust, distrust and intensity of Facebook use.Design/methodology/approachThis study employed quantitative survey research and collected panel data via an online professional survey platform. A total of 661 participants in the USA completed this study, and structural equation modeling (SEM) was used to test the theoretical model using Amos 20.FindingsBased on data from an online questionnaire (N = 661) in the USA, results showed that information trustworthiness and elaboration, users' self-efficacy of detecting misinformation and prescriptive expectancy of the social media platform significantly predicted both trust and distrust toward Facebook, which in turn jointly influenced users' intensity of using this information system.Originality/valueThis study contributes to the growing body of literature on information and relationship management and digital communication from several important aspects. First, this study disclosed the underlying cognitive psychological and social processing of online misinformation and addressed the strategies for future system design and behavioral intervention of misinformation. Second, this study systematically examined both trust and distrust as cognitive and affective dimensions of the human mindsets, encompassed the different components of the online information behavior and enriched one’s understanding of how misinformation affected publics' perceptions of the information system where it appeared. Last but not least, this study advanced the relationship management literature and demonstrated that a trustful attitude exerted a stronger influence on the intensity of Facebook use than distrust did.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/OIR-04-2020-0130

Authors: Wake Anthony , Davies Jill , Drake Celia , Rowbotham Michael , Smith Nicola , Rossiter Rowena 
Published: December 2020

Purpose
This collaborative paper (working together) describes collaborative practice development and research by and with people from the learning disabilities community. This paper aims to show some of the activities which supported the collaborative practice development and research to show and encourage others to do more collaboration. The paper format is based on a previous collaborative paper published in the Tizard Learning Disability Review (Chapman et al., 2013).

Design/methodology/approach
The collaborative practice development and feasibility study [1] focuses on an intervention called Keep Safe. This is an intervention for young people with learning disabilities who are 12 years and older and have shown “out-of-control” or harmful sexual behaviour.

Findings
The paper gives examples of activities of the Keep Safe Advisory Group in planning, doing and thinking about Keep Safe development and feasibility. The authors list some good things and some difficulties in collaborating. They look at which parts of Frankena et al.’s (2019a) Consensus Statement on how to do inclusive research were done, which ones were not, and why.

Social implications
The paper ends with some thoughts about collaborating with people from the learning disabilities community: for people with learning disabilities, practitioners and researchers.

Originality/value
The paper is original in its illustration of collaborative practice development and research and measuring the activities against the inclusive research consensus statement.
Affective commitment, service quality and selected sub-dimensions of customer citizenship behaviour: a study of ride-hailing services
Authors: van Tonder Estelle , Petzer Daniël Johannes 
Published: December 2020

PurposeMarketing literature has made little progress on the connection between service quality and customer citizenship advocacy, helping and feedback sub-dimensions that may promote competitiveness. It is also unclear to what extent service quality may serve as an underlying motivation for explaining the relationship between affective commitment (a primary antecedent of customer citizenship) and the selected sub-dimensions. Consequently, the aim of the current research is to develop a customer citizenship behaviour model and address these matters in a peer-to-peer service context.Design/methodology/approachSurvey data were collected from 610 customers of a ride-hailing peer-to-peer service brand. Data analysis included structural equation modelling and bootstrapping.FindingsAffective commitment influences service quality. Service quality motivates customer citizenship behaviours directed towards the ride-hailing brand (feedback) and other customers (advocacy and helping). Service quality provides an indirect path for connecting affective commitment with the customer citizenship behaviours in varying degrees.Originality/valueThis study is the first to verify the relevance of all three customer citizenship behaviours in a single model as influenced by service quality. The current research is further a step forward in understanding the mediating role of service quality and its potential to ensure customers' feelings of attachment towards the brand are translated in citizenship actions. The findings are noteworthy, considering the varying service levels generally experienced in a peer-to-peer service environment. Peer-to-peer service brands may fall back on their emotional connection with customers to influence service judgements and ultimately benefit from customer citizenship behaviours.
Regional tourism satellite accounts: towards international comparability
Authors: Frenț Cristi , Frechtling Douglas C. 
Published: December 2020

Purpose
Despite its popularity as the only method for measuring the national economic contribution of tourism accredited by the United Nations and other multilateral economic institutions, Tourism Satellite Account (TSA) is rarely applied to subnational regions. The purpose of this paper is to examine to what extent the compliance with some general principles that any regional TSA should follow contributes to better international comparability of tourism statistics, one of the main goals of the TSA.

Design/methodology/approach
Through secondary research, 14 countries have been identified making regional TSA applications by complying most likely with these principles. In this regard, some methodological issues and main results obtained by these countries are investigated.

Findings
This study concludes that international comparability of TSA compilation data at regional levels should be a long-term goal once congruence is achieved between national and regional TSAs.

Research limitations/implications
The paper is not based on a primary data collection of TSA data.

Practical implications
The paper shows that regional TSAs might also be envisaged in the international comparability process of the national TSA data. It provides suggestions for how to use data to improve measurement of the economic contribution of tourism to regions.

Originality/value
It is the first paper addressing the international comparability of a sizable number of regional TSAs from 14 countries.
Relational exploration of the effect of work-related scheme on job satisfaction
Authors: Singh Sushmita , Singh S.K. , Srivastava Shashi 
Published: December 2020

Purpose
This study is an effort to explore a relationship between benefits of schemes (BoS) on the job satisfaction among handloom weavers. The weavers who are engaged in this work however face lot of challenges in terms of remuneration and working conditions. The government has been immense with various schemes that cater to the work-related problems. This paper aims to understand whether work-related support can be a predictor for job satisfaction in this context.

Design/methodology/approach
A cross-sectional survey design was used where 335 handloom weavers randomly participated in the study. Questionnaire was administered and scale was developed and validated for the measurement of BoS by using exploratory factor analysis and confirmatory factor analysis. The effect of the benefits on the job satisfaction was investigated by using structural equation modelling on AMOS 21 platform.

Findings
The outcome suggested that the BoS significantly affects the job satisfaction and a possible predictor. This which was indicated by the value of r^2, i.e.0.38 at significance level p < 0.001.

Research limitations/implications
The study suggests a method for analyzing the schemes/policies in the light of the benefits that schemes intend to deliver. This would help in making suitable modifications in the schemes order to have wider outreach and large-scale inclusion of the beneficiaries.

Practical implications
The study can be useful for the policymakers to further strengthen the features of the schemes. They might work in direction of inclusion of more handloom weavers in the framework of the schemes.

Originality/value
The effects of the work-related policies on job satisfaction is still in nascent stage, so this work is all about exploration in that area.
The landscape of extrapulmonary manifestations of human parainfluenza viruses: A systematic narrative review
Authors: Farahmand Mohammad , Shatizadeh Malekshahi Somayeh , Jabbari Mohammad Reza , Shayestehpour Mohammad 
Published: December 2020

AbstractHuman parainfluenza virus (HPIV) infection is associated with every kind of respiratory tract illnesses, including the common cold, laryngotracheobronchitis (i.e. croup), tracheobronchitis, bronchiolitis, and pneumonia, in both children and adults. Although HPIVs are common respiratory pathogens, there are increasing reports about extrapulmonary manifestations of HPIVs infection. Each of the HPIVs could produce infection of other organs (central nervous system, heart, myocardium, etc.) in all age groups who are either immunocompetent or immunocompromised. This review aimed at summarizing the available data on clinical manifestations of HPIV infection outside the respiratory tract from 1961 to 2020. The findings support the possibility of extrapulmonary infections that were thought to be due to rare host genetic or immunologic defects in infected patients. These findings highlight the fact that extrapulmonary dissemination of HPIV can occur, but the association is not clearly demonstrated. Our data support the hypothesis that HPIV infection is one of the possible causes of these alterations and may even be the direct cause in some cases.
Interferon III‐related IL28RA variant is associated with rheumatoid arthritis and systemic lupus erythematosus and specific disease sub‐phenotypes
Authors: Drehmer Manuela Nunes , Castro Gabriel Vaisam , Pereira Ivanio Alves , de Souza Ilíada Rainha , Löfgren Sara Emelie 
Published: December 2020

AbstractBackgroundThe interferon pathways have been commonly implicated in autoimmune disease development but the identity of the genes involved has not yet been fully clarified. Variation in genes involved in interferon pathways is expected to have a role in the etiology of these diseases.MethodsThe potential association of a polymorphism in the IL28RA gene, involved in these pathways, with susceptibility to systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) and disease‐related phenotypes was investigated in 603 Brazilian individuals (354 well‐characterized SLE and RA patients, and 249 controls). IL28RA (rs4649203) variant was genotyped by TaqMan assay. Statistical analysis was performed including both diseases and a comprehensive list of patient clinical manifestations.ResultsThe rs4649203‐G (minor) allele was associated with SLE and RA occurrence and was shown to be a risk factor for serositis and anemia among SLE patients as well as a protective factor for rheumatoid vasculitis and rheumatoid nodules in RA patients, suggesting an association with a milder form of the disease.ConclusionsThe IL28RA gene may contribute to SLE and RA susceptibility and to specific clinical manifestations of the diseases.
