Toward Automating HIV Identification: Machine Learning for Rapid Identification of HIV-Related Social Media Data
Authors: Young Sean D. , Yu Wenchao , Wang Wei 
Published: January 2017

Introduction:“Social big data” from technologies such as social media, wearable devices, and online searches continue to grow and can be used as tools for HIV research. Although researchers can uncover patterns and insights associated with HIV trends and transmission, the review process is time consuming and resource intensive. Machine learning methods derived from computer science might be used to assist HIV domain experts by learning how to rapidly and accurately identify patterns associated with HIV from a large set of social data.Methods:Using an existing social media data set that was associated with HIV and coded by an HIV domain expert, we tested whether 4 commonly used machine learning methods could learn the patterns associated with HIV risk behavior. We used the 10-fold cross-validation method to examine the speed and accuracy of these models in applying that knowledge to detect HIV content in social media data.Results and Discussion:Logistic regression and random forest resulted in the highest accuracy in detecting HIV-related social data (85.3%), whereas the Ridge Regression Classifier resulted in the lowest accuracy. Logistic regression yielded the fastest processing time (16.98 seconds).Conclusions:Machine learning can enable social big data to become a new and important tool in HIV research, helping to create a new field of “digital HIV epidemiology.” If a domain expert can identify patterns in social data associated with HIV risk or HIV transmission, machine learning models could quickly and accurately learn those associations and identify potential HIV patterns in large social data sets.
Improved Kinect sensor based motion capturing system for gait assessment
Authors: Müller Björn , Ilg Winfried , Giese Martin A. , Ludolph Nicolas 
Published: January 2017

AbstractOptical motion capturing systems are expensive and require substantial dedicated space to be set up. On the other hand, they provide unsurpassed accuracy and reliability. In many situations however flexibility is required and the motion capturing system can only temporarily be placed. The Microsoft Kinect v2 sensor is comparatively cheap and with respect to gait analysis promising results have been published. We here present a motion capturing system that is easy to set up, flexible with respect to the sensor locations and delivers high accuracy in gait parameters comparable to a gold standard motion capturing system (VICON). Further, we demonstrate that sensor setups which track the person only from one-side are less accurate and should be replaced by two-sided setups. With respect to commonly analyzed gait parameters, especially step width, our system shows higher agreement with the VICON system than previous reports.
Overlap among spatial memories triggers repulsion of hippocampal representations

Published: January 2017

SUMMARYAcross the domains of spatial navigation and episodic memory, the hippocampus is thought to play a critical role in disambiguating (pattern separating) representations of overlapping events. However, the mechanisms underlying hippocampal pattern separation are not fully understood. Here, using a naturalistic route-learning paradigm and spatiotemporal pattern analysis of human fMRI data, we found that hippocampal representations of overlapping routes gradually diverged with learning to the point that they became less similar than representations of non-overlapping events. This representational ‘reversal’ of the objective route similarity (a) was selective to the hippocampus, (b) only occurred for the specific route segments that were shared across routes, and (c) was predicted by the degree to which individual hippocampal voxels were initially shared across route representations. These findings indicate that event overlap triggers a repulsion of hippocampal representations—a finding that provides critical mechanistic insight into how and why hippocampal representations become separated.
Flood vulnerability and relocation readiness in Zimbabwe
Authors: Mavhura Emmanuel , Collins Andrew , Bongo Pathias Paradzayi 
Published: January 2017

PurposeThe purpose of this paper is to examine vulnerability conditions to flood disasters in Tokwe-Mukorsi community, Zimbabwe and identifies the barriers that constrained the community from relocating to safe sites.Design/methodology/approachUsing a questionnaire survey, field observations and interviews, the paper examines the biophysical and social vulnerability of the Tokwe-Mukorsi community, Zimbabwe, as well as the barriers that prevented it from relocating to safe sites. A thematic analysis of the large volumes of qualitative data from interviews and walk-through analyses was conducted. Descriptive statistics were used in analysing quantitative data from questionnaires.FindingsResults reveal that households living upstream and downstream of the dam were highly vulnerable to floods. Their biophysical vulnerability was partly induced by the construction of the dam whose basin encroached into the farming and settlement area. The extremely vulnerable group were households living below level of 660 m where five saddle dams had been constructed. The built environment of the community exhibited ignorance of standard building codes. The poor socio-economic conditions of the community and the incessant rains experienced over two weeks contributed to the flood disaster in early 2014. The Tokwe-Mukorsi community failed to relocate to safe places partly due to lack of compensation, absence of basic infrastructure and drought occurrence in relocation sites.Research limitations/implicationsThe calculation of social vulnerability indices is beyond the scope of this study due to non-availability of quantitative data at community level.Originality/valueThis paper provides a comprehensive understanding of why some communities may fail to relocate despite being highly vulnerable to flood disasters.
Improving community disaster resilience through scorecard self-testing
Authors: Ludin Salizar Mohamed , Arbon Paul Andrew 
Published: January 2017

Purpose
The purpose of this paper is to develop government and community-level critical thinking, planning, and action for improving community disaster resilience by reporting a study that sought to evaluate the possibility of using the Torrens Resilience Institute Australian Community Disaster Resilience (CDR) Scorecard in the Malaysian context.

Design/methodology/approach
A participatory action research approach (done in 2015) encouraged key people involved in managing the 2014 Kelantan floods in Malaysia’s north-east to participate in discussions about, and self-testing of, the CDR Scorecard to measure and improve their communities’ disaster resilience.

Findings
The CDR Scorecard can be useful in the Malaysian community context, with some modifications. Self-testing revealed that participating communities need to strengthen their disaster resilience through better communication, cross-community cooperation, maximizing opportunities to compare their plans, actions and reactions with those reported in research publications, and aligning their community disaster management with reported best practice internationally while acknowledging the need to adapt such practice to local contexts.

Research limitations/implications
There is a need for a Malaysia-wide, simple-to-use, standardized disaster resilience scorecard to improve communities’ quality, self-efficacy, and capability to facilitate improved disaster resilience.

Practical implications
The adaptation of Australian CDR Scorecard for used in the country.

Social implications
Awareness of CDR level will enhance community and government preparedness, mitigation, and responses to flood disaster.

Originality/value
This project is the first of its kind in Malaysia. It provides an example of the possibilities of using the CDR Scorecard globally in the form of a context-specific toolkit. The engagement of key people in the community in self-testing the Scorecard provides genuine, on-the-ground, real life data, giving others an understanding of local assessment of each community’s resilience level.
Knowledge sharing maturity model for Jordanian construction sector
Authors: Arif Mohammed , Al Zubi Mohammed , Gupta Aman Deep , Egbu Charles , Walton Robert O. , Islam Rubina 
Published: January 2017

Purpose
The purpose of this paper is to present a maturity model developed to assess knowledge sharing (KS) for the Jordanian construction sector.

Design/methodology/approach
The research was conducted in three stages. The first stage consisted of the review of literature and documenting variables from the literature that highlight influence on KS in organizations. The second stage was designed for maturity model development by identifying the cultural factors that affect KS in the Jordanian construction sector through questionnaires and interviews. Factor analysis was used to find possible relationships between the cultural variables followed by semi-structured interviews. In the third stage the initial maturity model was refined through another set of semi-structured interviews.

Findings
The model presented in the paper includes three levels of maturity. The first level identifies whether the variable barely exists in company’s KS practices. The second level shows the occasional techniques which the company uses to increase KS activities. The final level demonstrates the importance of the variable in affecting KS as being fundamentally ingrained in the company’s vision, mission, strategy and operations.

Originality/value
The research has developed a model that can be used to measure the KS in an organization. Although the model has been applied to the construction industry, it can easily be modified to fit in the other sectors.

Internet entrepreneurship and “the sharing of information” in an Internet-of-Things context
Authors: Yu Xiaoyu , Roy Sanjit Kumar , Quazi Ali , Nguyen Bang , Han Yuqing 
Published: January 2017

Purpose
For entrepreneurs operating in an Internet-of-Things (IoT) environment, it is essential to monitor more systematically, both the interaction with the consumers and the sharing of information among the consumers. The purpose of this paper is to identify the antecedents of word-of-mouth (WOM) in the online SME’s context in terms of consumers “citing the site” to peers in personal communications. A research model integrates the determinants of retail website-specific positive WOM communication, and proposes that WOM about a particular website is influenced by: site-level variables, that is, website quality and interactivity; and consumer-level variables, these being the site user’s satisfaction with and commitment to the website. The research advances the study of IoT entrepreneurship.

Design/methodology/approach
Data were collected from graduate and undergraduate students with business and entrepreneurship majors from a reputed school in the Northeast region of the USA, using an online survey. The hypotheses were then tested with SEM using AMOS 18.0.

Findings
Findings suggest that in an IoT context, WOM is influenced by a variety of factors of which the e-satisfaction and attitude toward website constructs play important roles. The study highlights the importance of the e-satisfaction construct and its metrics. E-satisfaction is not only a critical outcome metric, but also a primary predictor of customer e-loyalty, measured in terms of the customer’s positive attitude, stickiness and propensity to spread positive WOM.

Originality/value
The paper contributes to the entrepreneurship and IoT literature with a comprehensive framework of information sharing, interactivity and WOM, showing that specific antecedents drive consumers to cite and advocate for a website to fellow customers. The framework helps retail SME entrepreneurs in the IoT context to design appropriate strategies to influence website visitors’ endorsement of the site to fellow customers.
Dangers of workplace bullying: evidence from the Caribbean
Authors: Devonish Dwayne 
Published: January 2017

PurposeThe purpose of this paper is to examine whether person-related bullying, work-related bullying, and physically intimidating bullying predict three forms of job strain: physical exhaustion, work-related depression, and interpersonal counterproductive work behaviour (CWB-P).Design/methodology/approachThe study surveyed a wide cross-section of employees across a number of private sector organisations in a small developing country in the Caribbean region.FindingsThe prevalence rate of workplace bullying in the current Caribbean sample was 54 per cent. The regression results revealed that person-related bullying and work-related were positively related to work-related depression, whereas physically intimidating bullying and work-related bullying were positively related to CWB-P. None of the three forms of bullying predicted physical exhaustion. When the overall workplace bullying composite was used, all three job strains were significantly predicted.Research limitations/implicationsThe study utilised a cross-sectional self-report survey research design which does not permit causal inferences to be made. Common method variance is a possible limitation due to the use of self-report measure but this was ruled out by a Harman’s single factor test. Longitudinal research using a mixture of subjective and objective measures is needed to further investigate these relationships reported here.Practical implicationsFirst, social and interpersonal skills and emotional intelligence training and development opportunities should be provided to both managers and employees as a means of developing individuals who are socially aware, interpersonally competent, and emotionally intelligent in their interactions with each other at work. Second, a zero-tolerance approach should be communicated throughout the organisation evidenced by clear and explicit organisational policies against these acts. Third, it would be of good practical value to establish health and safety committees to identify, assess and tackle various psychosocial and other hazards at work (e.g. workplace bullying).Originality/valueThe study utilised a three-dimensional model of bullying at work (as well as a composite form of bullying) for predicting three forms of job strains among employees in various Caribbean workplaces.
Examining factors influencing sentencing decisions in school shootings
Authors: McKenzie Sherzine , William Crosby James 
Published: January 2017

Purpose
The purpose of this paper is to examine public perception of factors relevant in sentencing decision making for juvenile school shooters with a history of familial abuse, peer victimization, and school intervention.

Design/methodology/approach
Through the use of school shooting vignettes, 298 college-aged participants were randomly assigned to one of eight experimental conditions which differed based on the inclusion of the independent variables.

Findings
Results revealed no significant differences among the groups on the sentencing recommendations (i.e. psychiatric placement and incarceration). However, correlational analyses indicated that participants’ generally perceived they were influenced by the perpetrator’s history of peer victimization and the level of intervention offered by school personnel when the shooter was bullied. Further regression analyses suggested that participant characteristics such as race, gender, and prior experiences with bullying were among the most powerful predictors of agreement with sentencing recommendations.

Practical implications
Implications of the current findings raise questions as to the influence of peer victimization in civil and criminal court proceedings and its associated impact on the juvenile justice system, the educational system, and society’s desire for justice.

Originality/value
This study ambitiously ventures into exploring and understanding the relevant sociological, academic, and legal factors in addressing acts of school violence.
Sticky cost behavior: evidence from Egypt
Authors: Ibrahim Awad Elsayed Awad , Ezat Amr Nazieh 
Published: January 2017

PurposeThe purpose of this paper is to provide further empirical evidence on the asymmetric cost behavior, cost stickiness, in an emerging country, Egypt, which lacks academic research on this subject.Design/methodology/approachThis study uses multiple regression analysis to analyze the behavior of selling, general, and administrative costs (SG&A) and cost of goods sold (CGS) individually and jointly using total costs (TC) for the period 2004-2011 for Egyptian-listed firms. In addition, the study compares the cost behavior three years prior to and after the application of the corporate governance code in Egypt in 2007.FindingsThe results indicate that asymmetric cost behavior is common among Egyptian-listed firms as their SG&A, CGS, and TC were found to be sticky during the study period. The application of the corporate governance code in Egypt was found to affect the nature of SG&A – the behavior of these costs changed from sticky before the code to anti-sticky after the application of the code. Moreover, the code was found to affect the magnitude of stickiness of both CGS and TC.Originality/valueGreater awareness about cost behavior is important for emerging markets such as Egypt in order to protect investors’ interests and satisfy their information needs. To the best of our knowledge, this study is the first to provide evidence on cost stickiness in Egypt. Moreover, this study provides further evidence on the correlation between corporate governance and asymmetric cost behavior.
Audit prices and Big 4 fee premiums: further evidence from Thailand
Authors: Pratoomsuwan Thanyawee 
Published: January 2017

Purpose
Because there is mixed evidence regarding Big N fee premiums across countries, the purpose of this paper is to re-examine the phenomenon of audit price differentiations in the market for auditing services in Thailand. Although Hay et al. (2006) and Hay (2013) reviewed over 80 audit fee papers from 20 countries over 25 years, 13 of which were based in emerging economies, the understanding of the market for auditing services in Thailand remains limited. Because the Thai auditing market is also classified as a segmented market – i.e., a market that is less competitive for large-client firms and more competitive for small-client firms – this study tests audit price competition in an emerging audit market using Thailand as an example.

Design/methodology/approach
The traditional audit fee model is used to estimate audit fee premiums for a sample of over 300 non-financial companies listed on the Stock Exchange of Thailand in 2011.

Findings
Although the market for auditing services in Thailand is consistent with that described in Ferguson et al. (2013) – in which Big N audit firms dominate only the large-client segment – the results show that Big N auditors charge higher audit fees and earn higher fee premiums compared with non-Big N auditors in both the small- and large-client segments of the audit market.

Research limitations/implications
The evidence from this study reveals the existence of Big N fee premiums across market segmentations. Audit price differentials between Big N and non-Big N firms in both small- and large-client market segments might concern regulators regarding competition in the audit market with respect to whether the Big N firms are charging uncompetitive audit fees. These findings also imply that audit pricing varies across countries and the Big N price deferential is typically larger in emerging markets than in more developed audit markets and that it might be inadequate to study single-country audit pricing. However, the question whether the Big N fee premium results from Big N product differentiation is not directly investigated in this study.

Originality/value
Because earlier studies focusing on audit fee premiums have been conducted using data from the USA and Australia, the findings add to the limited evidence regarding audit fee premiums in an emerging country such as Thailand.
