Published: April 2020

PurposeThe dynamic global environment has increased the requirement of multidisciplinary entrepreneurial engineers. While studying entrepreneurial aspects of engineers, researchers have not considered inherent variability due to engineering majors. This study investigates the impact of entrepreneurial motivation (EM) on entrepreneurial intentions (EIs), to analyse the inherent entrepreneurial potential of engineering majors. The impact of entrepreneurial education has also been studied to proffer recommendations for policymakers.Design/methodology/approachThe design of this study is a survey conducted with 342 undergraduate students from three major engineering institutions in Pakistan using a close-structured questionnaire. Moderation analysis examines the entrepreneurial potential of different engineering majors. Analysis of variance (ANOVA) has been conducted to compare the EIs of different engineering majors and regarding the impact of entrepreneurial education on EIs.FindingsThe engineering major's role in the transformation of EM to EIs is multifaceted. EIs of students of a few engineering majors were found high. Entrepreneurship education improves the overall EIs of engineering students.Practical implicationsOutcomes of the study are useful for academia and policymakers to engage students of particular engineering majors, identified as entrepreneurial, in advanced entrepreneurial education and expose them to potential start-ups to have better value addition in specific sectors.Originality/valueThis is the first study in which engineering majors have been examined to bring insights about inherent entrepreneurial potential. This inherent entrepreneurial potential needs further exploration by academic researchers. The study has provided the base for future studies to institutionalize entrepreneurial education for different engineering majors.

Published: April 2020

PurposeOne of the most critical infrastructures is a data center (DC) because of it having many servers, computers and other equipment. DCs provide online services for various companies in the information technology (IT) industry. DC facilities should provide reliable online services while addressing the required quality and performance level considering maximum reliability and availability. The purpose of this study is to represent and classify the main findings in this area and to identify the main research gaps and shortcomings from the perspective of research.Design/methodology/approachThis paper provides an organized and systematic literature review focusing on topics regarding the operation and maintenance (O&M) management of DCs.FindingsAlthough there are several studies on O&M management systems for industrial systems and facilities, a limited number of studies with few methods and models have focused on DCs so far and these facilities require more attention. This paper identifies the issues and challenges for DC buildings and facilities and provides a conclusion of the findings to highlight the main research limitations for discovering new potential methods as future research opportunities.Research limitations/implicationsThe paper has highlighted the main practical issues of DCs in terms of maintenance management. Several research works have been discussed specifically for DC’s maintenance, which makes this paper a credible source for researchers, maintenance managers and companies involved in the area of DC. Because several of the reviewed literature were based on real case studies, decision-makers in the DC maintenance sector can take advantage of new research on maintenance scheduling to reduce the costs of maintenance.Originality/valueThe paper has presented a comprehensive list of frequent keywords in recent publications related to O&M management for DCs. It has provided a categorized list of publications based on by their topic, methodology and case study. Because this paper has discussed research works specifically for DC’s maintenance, it is a credible source for researchers, maintenance managers and companies involved in the area of DCs.
Financial restatements and sell-side analysts' stock recommendations: evidence from Malaysia
Authors: Qasem Ameen , Aripin Norhani , Wan-Hussin Wan Nordin 
Published: April 2020

PurposeThe purpose of this paper is to examine the influence of financial restatements on the sell-side analysts' stock recommendations.Design/methodology/approachThe sample of this study is based on a dataset from a panel of 246 Malaysian public listed companies for the period 2008 to 2013 (651 company-year observations). This study employs feasible generalized least squares regression.FindingsThis study finds a negative and significant relationship between restated companies and sell-side analysts' stock recommendations, which means that sell-side analysts issue less favorable stock recommendations for restated companies.Practical implicationsThe findings based on observations from an emerging economy complement the results of the US studies that analysts revise their earnings forecasts or recommendations downwards or drop coverage following financial restatements. The results of this study should be useful to capital market participants in understanding how analysts perceive and evaluate restated companies.Originality/valueThis paper expands the literature on financial restatements consequences in an emerging market which is largely unstudied. Prior research on analyst behavior towards restatements has focused on the consequences of restatements in terms of analyst following and forecast accuracy and dispersion. This study examines if and how the restatements affect the analysts' final output as reflected in the recommendation opinion, an area that has so far received little attention.
Refugee and immigrant health information needs
Authors: Zimmerman Margaret , Beam Heather 
Published: April 2020

Purpose
The purpose of this article is to provide insight into the HISB of this group. Immigrants and refugees are at a heightened risk for negative health outcomes upon resettlement. However, little scholarship reports on the health information-seeking behaviors and information needs of this population.

Design/methodology/approach
This study reports the findings of a study into the health information-seeking behaviors of 85 immigrant and refugee women. Women were asked to fill out a survey in their native language with both multiple choice and open-ended questions that requested information on what health information they required the most, which means they used to get it and paired this with demographic information.

Findings
In their own words, the participants reported information requirements regarding dental care, nutrition, general, reproductive and child health, as well as assistance in navigating the healthcare system. However, they believed that medical professionals are the most reliable sources of information and that they frequently turned to less credible sources such as friends and family or the internet. This may be because of their self-reported barriers of language and cost, as wells difficulty in understanding how to obtain information in the USA. What sources the participants used and what their informational needs were was influenced by their age, education and time living in the USA. Some comparisons are made with a group of local women in a similar study conducted concurrently by the author.

Originality/value
The research presented in this study provides a clearer understanding of the health information requirements and behaviors of refugee and immigrant women.
Ambidexterity responses to security risk institutional context
Authors: Ramirez Jacobo , Vélez-Zapata Claudia , Madero Sergio 
Published: April 2020

PurposeThis research aims to explore and analyze multinational enterprises (MNEs) and local firms' ambidexterity strategies to buffer against narcoterrorism impacts on their assets. The role of line managers (LMs), who have been deemed key players in the implementation of ambidextrous strategies, was investigated in detail.Design/methodology/approachThis paper presents a qualitative study based on 58 semistructured interviews with key employees, i.e. firm directors, human resource (HR) managers, LMs and their subordinates, in Colombia and Mexico over a three-year period.FindingsThe “culture of insecurity” that exists in Colombia and Mexico due to narcoterrorism and the lack of governmental enactment of coercive institutional pillars defines the common frames and patterns of the beliefs held by managers and employees working in such contexts. To ensure the survival of employees and firms in unsafe institutional contexts while managing normative pressures to compete worldwide, LMs, HR departments, and ultimately firms are forced to strategically exploit security measures and simultaneously implement innovative explorative strategies.Originality/valueThe findings suggest that ambidexterity strategies in unsafe institutional contexts represent an organizational advantage for competing worldwide while surviving in such contexts. This study contributes to the literature by linking ambidexterity and new institutionalism research in a robust framework with which to examine employment relationships in unsafe institutional contexts.
What does (and does not) affect crime in India?
Authors: Hazra Devika 
Published: April 2020

PurposeThis paper uses data from 2010 to 2016 across 32 states and union territories to investigate the determinants of crime in India. Results indicate the significance of macroeconomic, demographic, socioeconomic and deterrence factors in accounting for various categories of crime.Design/methodology/approachDue to the evidence of heteroskedasticity and cross-sectional dependence, linear regression with panel-corrected standard errors is implemented.FindingsIt has been found that among the macroeconomic factors, only GSDP per capita was found relevant in explaining total crime rates. However, the unemployment rate and price level are crucial in explaining some categories of crime. The demographic factor, that is, population density, socioeconomic factors, that is, income inequality, poverty rate, literacy rate exhibit important and significant relationship with crime rates in India. Further, out of the four deterrence factors, charge-sheeting rate, conviction rate, pendency in police cases are important in explaining various categories of crime rates in India.Originality/valueWhile implications of some socioeconomic variables are consistent with those found in previous studies, literacy rates and deterrence variables were found to have a positive association with crime. In particular, in a developing country such as India, white-collar crimes tend to increase as literacy rates increase. This calls for implementing policies that lead to greater employment opportunities for the educated masses. This paper also sheds light on the relationship between deterrence factors and crime rates in India. Deficiencies in the legal and judicial system have been detrimental to the nation's ability to curb crime rates.

Published: April 2020

PurposeTo understand consumer brand engagement processes in luxury fashion brands. Grounded on the brand engagement in self-concept (BESC), this study examines key drivers (i.e. value co-creation, social media marketing (SMM) activities, brand self-connection and brand image) of BESC that in turn, enhance brand loyalty and positive word-of-mouth (WOM) in the context of luxury fashion brands.Design/methodology/approachA descriptive survey approach was utilized and data were analyzed using structural equation modeling (SEM).FindingsThe findings reveal that value co-creation, SMM activities and brand self-connection are significantly related to BESC and subsequently, BESC is related to both brand loyalty and positive WOM. However, brand image is not related to BESC and brand loyalty but shows a strong relationship with WOM.Originality/valueThe recognition that consumer experiences add significant value to a brand drives companies to engage with their consumers focusing on the self-concept.

Published: April 2020

PurposeThe sociodemographic determinants of insufficient fruit and vegetable (FV) consumption in the general population in Thailand remain understudied. The purpose of this study was to investigate the association between sociodemographic characteristics and insufficient FV consumption in Thailand.Design/methodology/approachThis nationally representative survey employed a cross-sectional multi-stage sampling design. A total of 6,991 individuals aged 15 years or older participated in the study. Information on participants' FV consumption and sociodemographic characteristics were collected via questionnaire. The data were analyzed using binary logistic regression.FindingsThe overall prevalence of insufficient FV consumption in the study sample was 65.6%. Age of the participants, sex, marital status, place of residence, occupation, income and education were found to be significantly associated with insufficient FV consumption among this sample of the Thai population.Originality/valueFindings suggest the need for promotion of FV consumption and intervention policies aimed at increasing FV intake by taking into account sociodemographic characteristics of the population.

Authors: DeLorme Denise E. , Stephens Sonia H. , Bilskie Matthew V. , Hagen Scott C. 
Published: April 2020

AbstractThis paper reports on the process and results of focus groups conducted as stakeholder engagement for a two‐year, marine extension agency‐sponsored interdisciplinary project in coastal Louisiana, USA. The project involved refining the topographic features (eg flood protection infrastructure) of a computational storm surge model using local knowledge of elevation data. Coastal Louisiana experiences continual changes to the built and natural environment and persistent land loss, necessitating frequent adjustments to real‐time storm surge and restoration planning models to make them more useful for decision‐makers. Stakeholder involvement ensured accurate updates to the real‐time computational system and accessible and understandable modelling results displayed by an interactive decision‐support tool. The findings provide insights and recommendations from various practitioners that are applicable to decision‐support model and tool development for coastal hazard emergency response.

Published: April 2020

AbstractThe objective of this study was to evaluate the antibacterial effect of Chinese wild blueberry extract and its fractions against Listeria monocytogenes, Staphylococcus aureus, Salmonella Enteritidis, and Vibrio parahaemolyticus. Chinese wild blueberry (Vaccinium uliginosum) crude extract (BBE) was obtained using methanol extraction, and sugars plus organic acids (F1), phenolics fraction (F2), and anthocyanins plus proanthocyanidins (F3) fractions were separated using C‐18 Sep‐Pak columns. The minimal inhibitory concentration and minimal bactericidal concentration of each fractional component were determined using a two‐fold‐serial dilution method. Nucleic acid leakage (OD260 nm) and protein release (Bradford protein assay) were determined by spectrophotometry, to evaluate the permeability of the cell membrane. F3 was found to exhibit the greatest antimicrobial activity against the four tested strains, followed by F2, F1, and BBE. V. parahaemolyticus was the most sensitive to the all fractions, followed by S. Enteritidis, L. monocytogenes, and S. aureus. Survival curve analysis showed that the number of bacteria decreased from six log colony‐forming units (CFU) to less than 10 CFU after bacteria were treated with fractions for 12 hr, which demonstrated the bactericidal effect of blueberry fractions. Furthermore, when the pathogens were treated with fractions for 2 hr, the OD260 nm and OD595 nm values increased significantly (P < 0.01), which indicated the significant release of nucleic acid and protein. The results from this study indicated that blueberry fractions, especially F3, inhibited the growth of foodborne pathogens by damaging their cell membrane, and may be developed as a natural preservative to prevent and control foodborne pathogens.Practical ApplicationA blueberry crude extract and its sugars plus organic acids, phenolics, and anthocyanins plus proanthocyanidins fractions, inhibited the growth of foodborne pathogens by destroying their cell membrane. Therefore, Chinese wild blueberries have potential as a natural preservative to prevent and control foodborne pathogens.

Published: April 2020

AbstractIntroductionAustralia’s first proton beam therapy (PBT) service, The Australian Bragg Centre for Proton Therapy and Research, is scheduled to open in the near future providing PBT for patients closer to home. Patients currently access Commonwealth funding for PBT via the Medicare Medical Treatment Overseas Program (MTOP). Proton versus photon treatment planning is a pre‐requisite for the MTOP application. The Royal Adelaide Hospital (RAH) Department of Radiation Oncology has been providing this since 2016. We aim to provide a descriptive overview of our proton versus photon treatment planning process, presenting a summary of the comparative planning results and the treatment pathways selected for the patients referred.MethodsAll patients referred to the RAH for comparative planning between January 2016 and December 2018 were included in the analysis. Comparative plans were generated for each case using Pinnacle or Eclipse treatment planning systems. The planning techniques used and plan quality metrics were reported.ResultsForty three patients were referred for comparative planning. The age range was 1–63 years, with the majority (72%) being paediatric patients (age ≤18 years). Of the 19 cases that have been submitted to MTOP, 16 have been accepted and 3 denied. Two of the accepted cases chose not to travel abroad for PBT. The other 14 cases have received PBT overseas.ConclusionsThe RAH has provided an important service to demonstrate the dosimetric difference between PBT and photon therapy for Australian patients, an important step in supporting the funding of patients for treatment overseas.
Accuracy of dual‐bolus CT in the diagnosis of active arterial bleeding in adult pelvic trauma
Authors: Harisis George N , Lee Jonathan TL , Clements Warren , Joseph Tim , Goh Gerard S 
Published: April 2020

AbstractIntroductionA single‐phase dual‐bolus CT (DB‐CT) simultaneously opacifies both arterial and venous systems and can be utilised in the trauma setting to aid in the diagnosis of active bleeding while also allowing for optimal assessment of the abdominal and pelvic viscera. Active bleeding can be venous or arterial, the latter being amenable to angiography and potentially embolisation. We aimed to establish the accuracy of single‐phase DB‐CT vs commonly performed portal venous CT (PV‐CT) in the diagnosis of active bleeding when compared to formal digital subtraction angiography as the gold standard.MethodsAll patients diagnosed with active bleeding on PV‐CT or DB‐CT at a level 1 tertiary centre over a 6‐year period and who subsequently proceeded to digital subtraction angiography (DSA) were included for analysis. The initial CT images were retrospectively reviewed by two consultant interventional radiologists who were blinded to the subsequent outcome of the DSA and to each other’s results. The sensitivity, specificity and inter‐observer agreement between the two readers was then able to be assessed.ResultsA total of 60 patients were included in the analysis. Sensitivity for the diagnosis for any active bleeding was high for both DB‐CT and PV‐CT (range 88.9%–100%) while diagnosis of specifically arterial bleeding was comparatively lower (51.9%–79%). Inter‐observer agreement for the identification of arterial bleeding was better for DB‐CT (fair) compared to PV‐CT (poor).ConclusionBoth PV‐CT and DB‐CT demonstrate high sensitivity in the diagnosis of any active bleeding though identification of specifically arterial bleeding is lower for both scanning methods. Nevertheless, inter‐observer reliability for the identification of arterial bleeding is higher for DB‐CT. Multi‐phase arterial and venous CT may yield better results and could be a focus for future studies.
Does policy uncertainty of the blockchain dampen ICO markets?
Authors: Zhang Shuyu , Zhang Dunli , Zheng Jianming , Aerts Walter 
Published: April 2020

AbstractPolicy uncertainty created by regulatory authorities regarding the blockchain matters for the initial coin offering (ICO) market. Using an ICO dataset from four major cryptocurrency exchanges, we find that higher policy uncertainty regarding the blockchain leads to a lower return and a lower trading volume of an ICO on its first trading day. Although ICOs are decentralised by design and less vulnerable to direct regulatory intervention, we conclude that blockchain policy uncertainty constitutes an important component of the information environment of ICO ventures.
