Construction of personal knowledge maps for a peer-to-peer information-sharing environment
Authors: Qin Chunxiu , Zhao Pengwei , Mou Jian , Zhang Jin 
Published: June 2018

Purpose
Browsing knowledge documents in a peer-to-peer (P2P) environment is difficult because knowledge documents in such an environment are large in quantity and distributed over different peers who organize the documents according to their own views. This paper aims to propose a method for constructing a personal knowledge map for a peer to facilitate knowledge browsing and alleviate information overload in P2P environments.

Design/methodology/approach
The research presents a method for constructing a personal knowledge map. The method adopts an ontology-concept-tree-based classification algorithm to recognize a peer’s personal knowledge structure and construct a personal knowledge map, and uses a self-organizing map algorithm to cluster and visualize the knowledge documents. The correctness of the created knowledge map is evaluated with a collection of abstracts of academic papers.

Findings
The method for constructing a personal knowledge map is the main finding of this research. The evaluation shows that the created knowledge map is good in quality.

Research limitations/implications
The proposed method provides a way for P2P platforms to understand their users’ knowledge background, as well as to improve the P2P platform environment. However, the proposed method will not help a peer when he has nothing in his individual knowledge document repository (i.e. the “cold start” problem). The method also requires a relatively good ontology base for a P2P document sharing system to use the method effectively.

Originality/value
It is novel that the proposed method organizes the knowledge documents related to a peer’s knowledge background into a personal knowledge map. Moreover, the created knowledge map combines the advantages of a hierarchical display and a map display. It has values for a distributed P2P environment to facilitate users’ knowledge browsing and to alleviate information overload.
Persuading end users to act cautiously online: a fear appeals study on phishing
Authors: Jansen Jurjen , van Schaik Paul 
Published: June 2018

Purpose
The purpose of this paper is to test the protection motivation theory (PMT) in the context of fear appeal interventions to reduce the threat of phishing attacks. In addition, it was tested to what extent the model relations are equivalent across fear appeal conditions and across time.

Design/methodology/approach
A pre-test post-test design was used. In the pre-test, 1,201 internet users filled out an online survey and were presented with one of three fear appeal conditions: strong fear appeal, weak fear appeal and control condition. Arguments regarding vulnerability of phishing attacks and response efficacy of vigilant online information-sharing behaviour were manipulated in the fear appeals. In the post-test, data were collected from 786 internet users and analysed with partial least squares path modelling.

Findings
The study found that PMT model relations hold in the domain of phishing. Self-efficacy and fear were the most important predictors of protection motivation. In general, the model results were equivalent across conditions and across time.

Practical Implications
It is important to consider online information-sharing behaviour because it facilitates the occurrence and success of phishing attacks. The results give practitioners more insight into important factors to address in the design of preventative measures to reduce the success of phishing attacks. Future research is needed to test how fear appeals work in real-world settings and over longer periods.

Originality/value
This paper is a substantial adaptation of a previous conference paper (Jansen and Van Schaik, 2017a, b).

Authors: Rastogi Mansi , Rangnekar Santosh , Rastogi Renu 
Published: June 2018

PurposeIt has been claimed that workplace flexibility is beneficial for employees as well as employers. However, not many studies have attempted to examine the impact of workplace flexibility on employees. The purpose of this paper is to examine the impact of flexibility dimensions on quality of work life (QWL) of employees.Design/methodology/approachData were collected from a sample of 380 middle-level employees from service and manufacturing sector in India. Analyses were carried out using multiple regressions with the help of SPSS AMOS 21.FindingsFlexibility in time and place as well as operations has a significant impact on QWL of middle-level employees. Additionally, flexibility in time and place is indicated to be a strong predictor for enhanced QWL particularly for married female employees as compared to their male counterparts. The type of organisation and sector also influences QWL of middle-level employees.Research limitations/implicationsThis study has projected theoretical justification indicating how workplace flexibility satisfies needs of middle-level employees and promotes their QWL. It contributes to positive psychology literature by illustrating empirical evidence supporting the crucial role of flexibility at workplace in enhancing QWL of employees in India.Practical implicationsThe findings may be valuable in all kinds of organisational settings when reviewing and proposing motivational employee well-being related policies. The empirical findings may have practical implications when it comes to designing jobs for enhanced work engagement.Originality/valueThe variables examined in this study reflect an understanding about how support mechanism at workplace creates a positive effect in employees’ well-being in unique cultural settings of India. Thus, this study is a significant contribution to the well-being literature in India.

Authors: Abduh Amirullah 
Published: June 2018

Purpose
The purpose of this paper is to explore lecturers’ perceptions on factors that affect the implementation of bilingual instruction (BI) policy in Indonesian higher education.

Design/methodology/approach
This qualitative study used 15 lecturers who taught in BI programs in three Indonesian universities. The data were gained through semi-structured interviews. The semi-structured interview data were analyzed via thematic approach.

Findings
The findings of the study suggest a number of factors influencing the implementation of BI, including the support from lecturers, leadership, and government. The availability of adapted curriculum and systematic assessment also influences the successful implementation of BI in Indonesian tertiary education.

Practical implications
The findings of this study have implications for the success of similar programs and the ways to gain understanding of BI within higher education contexts.

Originality/value
BI research is not new; however, little information is related to BI in Indonesia. This work contributes to a growing body of literature that explore BI and education factors within higher education setting. The significance of this study is to raise greater understanding of several important factors that influence the implementation of BI policy within university settings.

Published: June 2018

PurposeAs a business paradigm, social commerce (s-commerce) has brought about a new stage of innovation, and by extension, has transmuted the power from seller to buyer. S-commerce is a combination a commercial and social activities in which individuals may spread word of mouth (WOM) about their shopping experiences and knowledge and provide information about product and services to their to their friends. This kind of social interactions among individuals has increased the potentials of eWOM communication. Given such a backdrop, this paper aims to look into the influence of eWOM engagement on consumers’ purchase intention in s-commerce, which may complement the current effort of the research community in this area.Design/methodology/approachThis study used elaboration likelihood model, theory of reasoned action and social support theory to investigate the influence of eWOM engagement on consumers’ purchase intention in s-commerce. The study used 218 respondents to evaluate the proposed model using SmartPLS.FindingsThe empirical results indicate that information characteristics, consumer behavior and technological factors exert a positive influence on consumer purchase intentions. All hypotheses between attitude toward eWOM, information credibility, innovativeness, website quality and eWOM engagement are significant. Also, eWOM engagement has a significant positive influence on consumer purchase intention. However, information quality and social support does not have any significant relationship with eWOM engagement.Research limitations/implicationsThis study seeks to address the dearth of research in the field of s-commerce, especially as it relates to eWOM. The study proposes a new model and empirically validates the hypothesized relationships. This research can serve as a stepping stone for future research in this field.Practical implicationsThis study is one of the early studies focusing on the influence of eWOM engagement, especially in s-commerce. The study offers comprehensive and empirically validated factors pertaining to eWOM engagement in s-commerce. The results of this study are also important to practitioners and online companies’ managers. The study’s model has demonstrated the contextualization of what makes customers engage in eWOM and its influence in s-commerce. The study will also offer insights for firms on how to encourage eWOM engagement among customers.Originality/valueA new eWOM engagement model in s-commerce is proposed with consideration on information characteristics, consumer behavior, technological and social factors. The model is validated afterwards.
The institutional role of business school accreditation agencies: a systematic literature review
Authors: Teixeira Gislaine Cristina dos Santos , Maccari Emerson Antonio 
Published: June 2018

PurposeAccreditation is a growing phenomenon and has begun to permeate scientific studies, most of which are quantitative, since they focus on the process of accreditation and its positive or negative effects. Only a few studies have analyzed this phenomenon from the perspective of institutional theory. As there is no consensus regarding the performance of accreditation agencies, the purpose of this paper is to identify their institutional role in the global orientation of the organizational practices, values and decisions of business schools (BS).Design/methodology/approachA systematic literature review enabled us to identify scientific publications since 2002 that have used institutional theory when discussing BS accreditation agencies. An in-depth reading of these articles led us to identify the most frequent, similar and contrasting perspectives. Seven aspects were analyzed in each article: theme, research assumption, theoretical basis, method, research context, result and suggestions for future studies.FindingsThe findings suggest a certain duality in the role of these agencies. If, on the one hand, they are responsible for providing a quality seal, on the other hand, they promote legitimacy in the field by institutionalizing international rules.Originality/valueBy investigating the performance of these agencies as global institutional bodies, the authors extrapolated the traditional discussion on the dynamic of interaction between local actors who both influence the field and are influenced by it, a recurring theme in institutional theory.

Abstract

Salt marshes are a key coastal environment for their important role as nursery habitats for marine and estuarine fish and crustaceans. Salt marshes are variable environments where species can experience daily cyclic hypoxic stress, characterised by profound variations in oxygen partial pressure (pO2) from supersaturated conditions (~42 kPa) to extremely hypoxic conditions (~3 kPa) in ~12‐hr.

Here, under laboratory conditions, we assessed the physiological consequences of exposing the shrimp Palaemon varians, a species commonly found in the salt marshes of northern Europe, to the daily cyclic hypoxic regime currently experienced in its habitat in August (7.1 ± 1.8 hr/day below 4.0 kPa). In the laboratory, adults were kept at water pO2 < 4.5 kPa for 7 hr each night and in normoxic conditions for the rest of the time.

We recorded an acceleration of P. varians’ moult cycle, which was 15% shorter in animals kept in cyclic hypoxia compared to animals in normoxia. Similarly, the pattern of expression of two cuticular proteins over an entire moult cycle indicated an effect of cyclic hypoxia on moult stage‐related genes. After 16 days, morphological changes to the gills were detected, with shrimps in cyclic hypoxia having a 13.6% larger lamellar surface area (measured in μm2/mg animal) than normoxic animals, which could improve gas exchange capacity. Overall, phenotypic and morphological data indicate that faster moulting is triggered in response to cyclic hypoxia, with the benefit that gill modifications can be prompted more rapidly in order to meet oxygen requirements of the body.

On the first experimental day, in cyclic hypoxic‐exposed animals, we recorded a 50% decrease in feeding rates (during hypoxic conditions) in comparison with normoxic animals. Similarly, ammonium excretion was reduced by 66%–75% during the 1st and 21st experimental day. Body size was reduced by ~4% after 28 days. Females that reproduced in cyclic hypoxic conditions reduced the amount of yolk in each egg by ~24%. Overall, results underline how, in a decapod shrimp living in a key coastal environment, many physiological parameters are impaired by a cyclic hypoxic regime that is currently found in its natural habitat.

A Primer on the ‘Reproducibility Crisis’ and Ways to Fix It
Authors: Reed W. Robert 
Published: June 2018

AbstractThis article uses the framework of Ioannidis () to organise a discussion of issues related to the ‘reproducibility crisis’. It then goes on to use that framework to evaluate various proposals to fix the problem. Of particular interest is the ‘post‐study probability’, the probability that a reported research finding represents a true relationship. This probability is inherently unknowable. However, a number of insightful results emerge if we are willing to make some conjectures about reasonable parameter values. Among other things, this analysis demonstrates the important role that replication can play in improving the signal value of empirical research.
Quantitative Sex Estimation Based on Cranial Traits Using R Functions
Authors: Nikita Efthymia 
Published: June 2018

AbstractThis paper presents an R script that quantifies the shape of selected cranial traits and automates sex estimation. The proposed functions were tested on two modern Greek assemblages. The discriminant variables input in the functions are calculated from a digital photograph of the lateral view of the cranium. The cranial outline is determined using the Canny edge detector and discriminant variables that quantify the shape of the glabella/frontal bone, mastoid process, and external occipital protuberance are computed. The best cross‐validated results for pooled sexes in the Athens Collection range from 84.2% to 87.3%, and increase up to 93.9% when half of the sample is used for training and the rest for prediction, while correct classification for the Cretan material is 80–90% for optimum combinations of discriminant variables. The greatest advantage of the proposed method is its straightforward and time‐efficient application.
Caecal infusion of the short‐chain fatty acid propionate affects the microbiota and expression of inflammatory cytokines in the colon in a fistula pig model
Authors: Zhang Yanan , Yu Kaifan , Chen Huizi , Su Yong , Zhu Weiyun 
Published: June 2018

SummaryShort‐chain fatty acids (SCFAs), particularly butyrate, are known to suppress inflammation, and regulate the gut bacterial ecology. However, little is known about propionate. We report here that propionate infusion in the caecum dramatically affected the structure of colonic microbiota of pigs based on 16s rRNA high‐throughput sequencing. Sixteen pig models were perfused with saline or sodium propionate by a fistula in the caecum. At d 28, all pigs were slaughtered for analysing bacterial metabolites, colonic microbiota and the expression of genes related to inflammation. The results showed that caecal infusion of sodium propionate increased the concentration of propionate and decreased the butyrate concentration in colonic content. For biogenic amines, the tyramine concentration was increased, while the concentration of cadaverine was decreased by infusion of sodium propionate. Furthermore, at the level of phylum, propionate increased the abundance of Bacteroidetes and reduced the abundance of Firmicutes. Prevotella and Bacteroides counts were increased, while Turicibacter abundance was decreased at the level of genus. Real‐time qPCR showed that the expression of NF‐κB and IL‐18 was upregulated by propionate infusion, whereas no significant differences were observed for the expression of other genes related to inflammatory processes. Taken together, these results provide a new evidence for the role of short‐chain fatty acid propionate on the composition of microbial community and inflammatory cytokines.
Wording wisely: Including prevalence data and evidence based clinical outcomes of spinal and musculoskeletal degeneration in radiology reports
Authors: Doss Arockia 
Published: June 2018

SummaryDiseases due to spinal and musculoskeletal degeneration are a common cause of disability worldwide. In the past few years, there has been widespread increase in the use of imaging in these conditions. However, the years lived with a disability has not declined. There is a growing body of evidence that imaging in spinal and musculoskeletal conditions due to degeneration and ageing is unnecessary and contributes to increasing costs. More worrying is the evidence that imaging may also cause harm due to prevalent use of cortisone injections and surgical procedures that are justified on the basis of a radiology report. Prevalence studies and randomized controlled trials in the past decade have provided a better understanding of these diseases beyond the morphological findings described in a radiology report. A radiology report supplemented with information on normal age related appearances, natural progression, available evidence on treatment and subsequent health outcome may help the referrer and patient understand the relevance of imaging findings in a patient specific context. This may reduce unwanted procedures, unnecessary costs and patient harm. This article attempts to provide such information for the most common degenerative diseases of the spine and musculoskeletal system.

Published: June 2018

BackgroundPsychotic experiences (PEs) are common in childhood and have been associated with concurrent mental disorder and poorer global functioning. Little is known about the effects of childhood PEs on future functioning. We investigated the effects of childhood PEs on global functioning from childhood into early adulthood.MethodFifty‐six participants from a community sample completed all three waves of the Adolescent Brain Development study (T1 Age: 11.69, T2 Age: 15.80 T3Age: 18.80). At each phase, participants completed a clinical interview assessing for PEs, mental disorder and global function. Repeated measures models, adjusted for mental disorder and gender, were used to compare current (C‐GAF) and most severe past (MSP‐GAF) functioning in participants who had reported PEs in childhood and controls.ResultsParticipants with a history of PEs had significantly poorer C‐GAF (P < 0.001) and MSP‐GAF scores (P < 0.001). Poorer functioning was evident in childhood (C‐GAF: P = 0.001; MSP‐GAF: P < 0.001), adolescence (C‐GAF: P < 0.001; MSP‐GAF: P = 0.004) and early adulthood (C‐GAF: P = 0.001; MSP‐GAF: P = 0.076).DiscussionChildren who report PEs have persistently poorer functioning through to early adulthood. The longitudinal association between childhood PEs and global functioning highlights the underlying global vulnerability in children reporting PEs, beyond what can be explained by mental disorder.

AbstractAimsTo test the effectiveness of a theoretically based text‐message intervention to reduce binge drinking among socially disadvantaged men.DesignA multi‐centre parallel group, pragmatic, individually randomized controlled trial.SettingCommunity‐based study conducted in four regions of Scotland.ParticipantsA total of 825 men aged 25–44 years recruited from socially disadvantaged areas who had two or more episodes of binge drinking (> 8 UK units on a single occasion) in the preceding 28 days: 411 men were randomized to the intervention and 414 to the control.Intervention and comparatorA series of 112 interactive text messages was delivered by mobile phone during a 12‐week period. The intervention was structured around the Health Action Process Approach, a comprehensive model which allows integration of a range of evidence‐based behaviour change techniques. The control group received 89 texts on general health, with no mention of alcohol or use of behaviour change techniques.MeasurementsThe primary outcome measure was the proportion of men consuming > 8 units on three or more occasions (in the previous 28 days) at 12 months post‐intervention.FindingsThe proportion of men consuming > 8 units on three or more occasions (in the previous 28 days) was 41.5% in the intervention group and 47.8% in the control group. Formal analysis showed that there was no evidence that the intervention was effective [odds ratio (OR) = 0.79, 95% confidence interval (CI) = 0.57–1.08; absolute reduction 5.7%, 95% CI = −13.3 to 1.9]. The Bayes factor for this outcome was 1.3, confirming that the results were inconclusive. The retention was high and similar in intervention (84.9%) and control (86.5%) groups. Most men in the intervention group engaged with the text messages: almost all (92%) replied to text messages and 67% replied more than 10 times.ConclusionsA theoretically based text‐messaging intervention aimed at reducing binge drinking in disadvantaged men was not found to reduce prevalence of binge drinking at 12‐month follow‐up.
