Published: December 2019

AbstractTranscranial direct current stimulation (tDCS) has been studied to enhance extinction-based treatments for anxiety disorders. However, the field shows conflicting results about the anxiolytic effect of tDCS and only a few studies have previously observed the extinction of consolidated memories.Off-line tDCS modulates subsequent fear response (fear recall and fear extinction) neural activity and connectivity, throughout changes in the fear pathway that is critically involved in the pathogenesis of anxiety disorders.Thirty-four women participated in a two-day fear conditioning procedure. On day 1, women were randomly assigned to the control group (n=18) or the tDCS group (n=16) and went through a fear acquisition procedure. On day 2, the tDCS group received 20min tDCS at 1mA [cathode – F4; anode – contralateral deltoid] immediately before extinction and while inside the MRI scanner. The control group completed the extinction procedure only.fMRI whole brain contrast analysis showed stimulation dependent activity patterns with the tDCS group showing decreased neural activity during the processing of the CS+ and increased activity during the processing of the CS, in prefrontal, postcentral and paracentral regions, during late extinction. PPI analysis showed tDCS impact on the connectivity between the left dorsolateral prefrontal cortex and three clusters along the cortical–amygdalo–hippocampal– cerebellar pathway, during the processing of the CS+ in late extinction (TFCE corrected at p <.05).The increased neuronal activity during the processing of safety cues and the stronger coupling during the processing of threat cues might well be the mechanisms by which tDCS contributes to stimuli discrimination.HighlightsThe anxiolytic effect of cathodal tDCS is controversial.We show cathodal tDCS modulatory effect on delayed extinction of the fear response.Cathodal tDCS modulates the processing of safe and threatening cues.Cathodal tDCS modulates the activity and connectivity of the fear network.

AbstractObjectivesTo examine the association between hand grip strength (HGS) and cognitive function, and the potentially moderating effects of cognitive reserve on this relationship using a sample of community dwelling elderly in China.MethodsThe subjects included 1291 community-dwelling elderly aged 60 or over and without dementia who participated in the baseline survey of an elderly cohort in Anhui province, China. Cognitive function was assessed using Mini-Mental State Examination (MMSE) and HGS was measured using an electronic grip strength dynamometer. The education (EDU) in early life, cognitive level of the job (CLJ) in middle age, cognitive leisure activities (CLA) in late life, and other covariates were collected through a face-to-face interview and physical examination.ResultsThe differences in MMSE scores across tertiles of HGS were significant (MMSE scores across tertiles of HGS: 20.26±7.02 vs 22.83±5.99 vs 24.76±6.36,F=62.05,P<0.001). After adjustment for covariates, the lower tertiles of HGS was related to lower MMSE scores when compared to the upper tertiles of HGS (β=β[95%CI]: −2.02[−2.87~−1.17],P<0.001). However, no significant association existed between the intermediate tertiles of HGS and lower MMSE scores (β=β[95%CI]: −0.28[−1.05~0.50],P=0.483). Moderation analyses revealed that the correlation between the lower tertiles of HGS and decreased MMSE scores was less pronounced in middle EDU (β=β[95%CI]: −1.62[−3.22~−0.02],P=0.047), and in middle CLJ (β=β[95%CI]: −2.17[−3.31~−1.24],P<0.0001) than in low EDU (β=β[95%CI]: −2.46[−3.80~−1.12],P<0.0001), and in low CLJ (β=β[95%CI]: −3.72[−6.92~−0.53],P=0.023). Furthermore, this relationship was not significant among the elderly with high EDU or the high CLJ.ConclusionsThe lower HGS is associated with poor cognitive function in older age, and cognitive reserve may attenuate or eliminate the relationship of lower HGS with cognitive function.

Published: December 2019

AbstractHow organisms achieve sustained peripheral tolerance throughout their lifetime, a correct immune discrimination between self and non-self, remains poorly understood. Host-microbiome interactions carry fundamental information that facilitates this process. We hypothesize that commensal microbes are under evolutionary pressure to develop epitopes that, when presented along with other antigens from their own bacterial community, lead to an overall tolerogenic self classification by the host immune system. Hosts, which have co-evolved with commensals, may rely on mimotopes, bacterial epitopes that are indistinguishable from key self epitopes, as a homeostatic feedback mechanism to establish and maintain tolerance. Using a probabilistic sequence model of peptide mimicry, we show that the gut microbiome contains a set of genes that are likely to trigger identical immune responses to insulin B 9–25, a widely distributed self epitope across tissues and the primary autoantigen in type 1 diabetes. Similarities in the antigen receptor sequences determined from CD4 T cells reacting to insulin epitopes and mimotopes provide experimental evidence for mimicry. All predicted high posterior probability mimotopes belong to the transketolase superfamily, an enzyme that allows efficient harvest of commensal-derived sugar polymers and dietary fibre, an advantage during host colonisation. Microbial transketolase upregulation during infant weaning coincides in time with the peak in autoantibody development against insulin. Abundance changes in bacterial genera that carry these mimotopes have also been observed to precede disease diagnosis. Our findings suggest gut dysbiosis followed by immune response to insulin mimotopes as a primary cause of type 1 diabetes, and may contribute towards unraveling similar causal patterns in a wide variety of disorders.

Authors: Jeong Yunduk , Kim Sukkyu 
Published: December 2019

PurposeThe purpose of this paper is to explore structural relationships between quality, destination image, perceived value, tourist satisfaction and destination loyalty with emphasis on the mediating effect of tourist satisfaction on relations between destination image and destination loyalty, and between perceived value and destination loyalty in the context of small-scale sporting events.Design/methodology/approachConstruct validity of the measurement scale was verified by confirmatory factor analysis, factor loadings, average variance extracted, construct reliability and correlation analysis. Reliability of the measurement scale was verified by Cronbach’sαanalysis. A structural equation modeling test with maximum likelihood estimation was used to test structural relationships between variables in the proposed model using the responses of 311 participants.FindingsResults showed significant and powerful impacts of: event quality, destination image and perceived value on tourist satisfaction; destination image, perceived value, and tourist satisfaction on destination loyalty and demonstrated; and tourist satisfaction fully mediates relationships between destination image and destination loyalty, and between perceived value and destination loyalty.Originality/valueThe study shows: it is meaningful to include quality and value in tourism destination image-satisfaction-loyalty models; provides empirical evidence that tourist satisfaction fully mediates the relation between perceived value and destination loyalty; and confirms small-scale as well as large-scale sporting events should be viewed as important aspects of marketing strategies aimed at improving quality, image, value, satisfaction and loyalty.
Internationalization of SMEs and market orientation
Authors: Billore Soniya , Billore Gautam 
Published: December 2019

Purpose
This paper aims to study the context of market orientation and the contribution of customer knowledge, networking and cultural knowledge to market orientation particularly to the internationalization of firms in developing economies.

Design/methodology/approach
A multiple case approach is adopted with four Swedish firms internationalizing to the Indian market. The data was obtained through personal interviews and typically lasted an hour. Follow-up questions were obtained by personal meetings or on Skype. Data was collected over a period of seven months during 2016-2017.

Findings
This study highlights the importance of customer knowledge, networking and cultural knowledge for foreign small and medium enterprises (SMEs) in the initial stages of internationalization. It proposes that a holistic market sensing of the target market can be achieved as the three constructs contribute to the market orientation of the firms and help in devising relevant strategic fit with the market.

Research limitations/implications
The sample size is small due to a limited number of Swedish SMEs who have the experience of operating in the Indian market. Future studies may include the Nordic region, and a quantitative approach for testing market orientation frameworks can be adopted.

Originality/value
This study lifts the concept of market sensing as customer knowledge, networking and cultural knowledge strengthen the market orientation of the firm. It addresses the research gap about limited research in developing market contexts for SME internationalization and specifically on Swedish SMEs in the Indian market.
Comparison of study motivation and job expectations of Russian full-time and part-time university students
Authors: Sikyr Martin , Basmanova Nina Ivanovna , Abrashkin Mikhail 
Published: December 2019

Purpose
The purpose of this paper is to present the results of the authors’ questionnaire survey focused on the comparison of study motivation and job expectations of full-time and part-time students of Russian universities and identify main problems of higher education and graduate employment and suggest their possible solutions.

Design/methodology/approach
The authors’ questionnaire survey was conducted from March to October 2018. The respondents were full-time and part-time bachelor’s and master’s students from 30 regions across Russia. The relevant data were obtained from 1,051 students. The data analysis was based on the calculation of relative frequencies (as a share from the total number of respondents) and the evaluation of the dependence of responses on the form of study (full-time students and part-time students) using contingency tables and χ2 tests of independence.

Findings
The results of the authors’ questionnaire survey support the assumption that the current generation of full-time and part-time students of Russian universities studies to succeed in the future. Surveyed university students certainly have a high motivation to study, but at the same time, they seem to have too high expectations about their future work and career, which can negatively affect their future success in their jobs if they do not have appropriate knowledge, skills and abilities.

Originality/value
The results of the authors’ questionnaire survey show some unique tendencies in the Russian university students’ attitudes to study, work and career that are worth attention both from the point of view of universities and from the point of view of employers and their current approaches to the education and the employment of the current generation of young people. The results open up new possibilities for further research focused on the higher education and the employability of the new generation of work force.
Behavioural propensities and financial risk tolerance: the moderating effect of ethnicity
Authors: Rahman Mahfuzur , Albaity Mohamed , Isa Che Ruhana 
Published: December 2019

PurposeThe purpose of this paper is to explore the influence of several core behavioural propensities on financial risk tolerance (FRT). Additionally, this paper examines the moderating effect of ethnicity on the relationship between behavioural propensities and FRT.Design/methodology/approachA sample of 1,204 completed and usable questionnaires were collected from undergraduate students majoring in business, economics and finance and analysed them using SmartPLS 2.0 software.FindingsThe findings reveal that propensity for trust has the highest impact on FRT followed by propensity for regret and happiness in life, while propensity for social interaction is not significantly associated with FRT. Ethnicity significantly moderates the relationship between three behavioural propensities (propensity for regret, propensity for trust and happiness in life) and FRT.Originality/valueThis study contributes to the assessment of individuals’ FRT incorporating behavioural propensities, which in turn contributes to the field of behavioural finance.
“Don’t look down on us!”
Authors: Miles Glenn Michael , Blase Olivia , Clark Katie , Ding Rachel J. , Geyer Theresa 
Published: December 2019

Purpose
Although some research has been done with entertainment workers in KTV bars, little has been done to gain a qualitative understanding of the vulnerabilities of masseuse women. This is due to a prevalent focus on girls under 18 years, thereby excluding most masseuses. The paper aims to discuss these issues.

Design/methodology/approach
In total, 98 female participants completed an interview answering both open and closed questions concerning relationships, stigma and discrimination and personal sexual abuse among other topics.

Findings
This study finds that many women working in the massage parlor industry are vulnerable to various threats, including sexual exploitation and abuse. Dependency structures within the massage parlor as well as with their families seem to play a key role in the life situations that can be positive as well as negative, and in some cases both.

Social implications
The findings provide a baseline evaluation of the vulnerable conditions of the massage industry for women in Cambodia. Specifically, that stigma, discrimination, physical and sexual abuse, as well as a lack of access to education are all vulnerabilities not commonly covered, especially with adult women working in the entertainment industry. This research has been adapted from the original transcript “Strive, No Matter What” (Miles et al., 2014).

Originality/value
The paper seeks to understand the reality of life and vulnerabilities as perceived by Phnom Penh’s female masseuses in the lower-priced massage parlors which is largely unknown.
Effect of vibration on power loss of angular contact ball bearings
Authors: Zheng De-Xing , Chen W.F. , Xiao Guanyun , Zheng Dateng 
Published: December 2019

Purpose
This paper aims to devote to the experimental analysis and modeling on the heat generation of angular contact ball bearings under vibration.

Design/methodology/approach
The experiments about vibration effect on bearing temperature are implemented. To explore the causes of bearing temperature rise, the shaft-bearing system is first simplified to a forced vibration model to analyze the bearing loads in vibration. Next, the vibratory-induced additional load is proposed and the spin power loss of balls is re-derived under vibration. The vibration-induced heat is integrated into a novel forecasting model of bearing power loss. For validation, the muti-node model for angular contact ball bearings is referred to create the thermal network of spindle front bearing, and then the contrast and discussion is done.

Findings
The simulation and test results both indicate that more energy is expended and more heat is generated with vibration. And the further quantitative comparisons between simulation results and experimental values of bearing temperature demonstrate the rationality and availability of constructed model on bearing heat generation.

Originality/value
The vibration-induced additional load is proposed and modeled, and the novel forecasting model for heat generation for high-speed angular contact ball bearings with vibration is constructed and validated.

First, the results of this study are not generalizable to a broader population. Second, this study explores behavioral patterns with respect to Chinese business culture only.Practical implicationsFirms can use the findings from this study to understand the consequence they can face when guanxi is absent in a buyer–supplier relationship.Originality/valueThis study attempts to offer a balanced perspective on the role of guanxi in a buyer–supplier relationship, particularly in the Chinese logistics industry, by considering how an absence of guanxi generates negative outcomes for firms.
Proactive or responsive market orientation for stronger service innovation capability: the moderating roles of contractual and relational governance
Authors: Wang Yonggui , Liu Fei 
Published: December 2019

PurposeBased on the business-to-business context in the service industry, this study aims to address two balancing problems that a supplier firm may face in an integrated framework: the trade-off between the two-dimensional market orientations (MO) (i.e. proactive and responsive MO) and the trade-off between two categories of governance mechanisms (i.e. contractual governance [CG] and relational governance [RG]). In doing so, the contingent effects of the governance mechanisms on the relationships between two-dimensional MO and service innovation capability (SIC) are empirically examined and tested.Design/methodology/approachA dyadic questionnaire survey of 168 services outsourcing firms’ project managers and strategy managers was used to collect data, which was then used to test the hypotheses by conducting hierarchical regression analysis.FindingsIt was observed that CG weakens the positive relationship between proactive MO (PMO) and SIC, while the positive impact of responsive MO (RMO) on SIC is strengthened. By contrast, RG plays an inverted U-shaped moderating role in the positive relationship between PMO and SIC. Nevertheless, the hypothesis that RG has an inverted U-shaped moderating effect on the effectiveness of RMO is not supported.Originality/valueDrawing on transaction cost economics and relational exchange theory, this study contributes to the existing literature on MO by revealing how CG and RG differentially shape the value of PMO and RMO.
Sharing information through book reviews in blogs
Authors: Savolainen Reijo 
Published: December 2019

PurposeThe purpose of this paper is to contribute to research on information sharing by drawing on the reader-response theory developed by Louise Rosenblatt. To this end, information sharing is approached by examining how bloggers communicate their reading experiences of fiction and non-fiction books.Design/methodology/approachThe conceptual framework is based on the differentiation between efferent and aesthetic reading stances specified by Rosenblatt. The efferent stance directs attention to what is to be extracted from reading for instrumental purposes such as task performance. The aesthetic stance focuses on what is being lived through during the reading event. Rosenblatt’s framework was elaborated by specifying eight categories of efferent reading and six categories of aesthetic reading. The ways in which bloggers communicate their responses to such readings were examined by scrutinising a sample of 300 posts from two book blogs.FindingsThe bloggers mainly articulated responses to efferent reading by sharing information about the content of the reviewed books, as well as their strengths and weaknesses. Responses to aesthetic reading were mainly articulated by describing how the bloggers experienced the narrative, what kind immersive experiences they had and what kind of emotions were felt during the reading process.Research limitations/implicationsAs the study is explorative in nature and focusses on a sample of blog posts, the findings cannot be generalised to depict how people share their responses to efferent and aesthetic reading in social media forums.Originality/valueThe paper pioneers by examining the potential of Rosenblatt’s theory in the study of sharing information about reading experiences in book blogs. The findings demonstrate that the categories of efferent and aesthetic reading can be elaborated further for the needs of information behaviour research.

Authors: Frings-Hessami Viviane , Sarker Anindita , Oliver Gillian , Anwar Misita 
Published: December 2019

Purpose
The purpose of this paper is to discuss the creation and sharing of information by Bangladeshi women participants in a community informatics project and to assess to what extent the information provided to them meets their short and longer-term needs.

Design/methodology/approach
The analysis is based on data collected during a workshop with village women in Dhaka and focus group discussions in rural Bangladesh in March and April 2019. The information continuum model is used as a framework to analyse the data.

Findings
The study shows that the women document their learning and share it with their families and communities and that they are very conscious of the importance of keeping analogue back-ups of the information provided to them in digital format. They use notebooks to write down information that they find useful and they copy information provided to them on brown paper sheets hung in the village community houses.

Practical implications
This paper raises questions about how information is communicated to village women, organised and integrated in a community informatics project, and more generally about the suitability and sustainability of providing information in digital formats in a developing country.

Originality/value
The paper shows how village women participants in a community informatics project in Bangladesh took the initiative to create and preserve the information that was useful to them in analogue formats to remedy the limitations of the digital formats and to keep the information accessible in the longer term.
