Differentiating the effects of entrepreneurs’ intelligence and educational attainment on venture outcomes
Authors: Blume Brian D. 
Published: September 2018

PurposeIntelligence or general mental ability (GMA) is a strong predictor of job performance across most occupations, and educational attainment has been shown to be a predictor of entrepreneurial outcomes. However, there has been little research examining the simultaneous effects of entrepreneurs’ GMA and educational attainment on their venture outcomes. The purpose of this paper is to examine the impact of these human capital resources on venture performance and survival.Design/methodology/approachUsing a sample of 234 self-employed entrepreneurs from a longitudinal database, regression analysis was employed to examine the predictors of venture performance. A hazard model was utilized to assess venture survival.FindingsEntrepreneurs’ intelligence influenced venture performance directly and indirectly via educational attainment. Entrepreneurs with higher GMA were subsequently able to obtain more education, and GMA had an indirect, positive influence on venture performance through this additional educational attainment. Findings also demonstrated an inverted-U, curvilinear effect on venture survival for GMA and educational attainment. This indicates that both intelligence and educational attainment should be considered when examining how likely entrepreneurs are to persist or survive in their ventures.Originality/valueEntrepreneurs with higher GMA had ventures that performed better and obtained more education, which influenced venture survival. These findings suggest that entrepreneurs’ intelligence is likely to be an important predictor of venture outcomes, as well as a source of entrepreneurs’ human capital acquisition. Therefore, GMA should have a more central role in the human capital discussion within the entrepreneurship literature.

Authors: Iman Nofie 
Published: September 2018

PurposeThis paper aims to explore the role of customer engagement during the production of services in a modular innovation. Modularity can be used to explain the structure and relationship in services innovation.Design/methodology/approachThe authors explore the theory of modularity focussing on the context of consumer engagements. They adopted ideas from product modularity and approach services using modular principle.FindingsContrary to the extant literature, the authors are content that the transactions between the participants were mainly conducted at thick crossing points. By focusing on thin crossing point, the service provider will achieve better overall service structure.Research limitations/implicationsThere is a need to focus on specifying interface to define how service modules and service providers interact with the customer within the service.Practical implicationsBy engaging customer, modular principle can help firms achieve cost efficiency, higher product and process variety, as well as better response to individual customer needs.Originality/valueThis paper scrutinises the engagement of customer and conceptualises the role of customer in modular innovations that have been previously neglected.
Trends and causes of socioeconomic inequalities in maternal healthcare in Ghana, 2003–2014
Authors: Fenny Ama Pokuaa , Asuman Derek , Crentsil Aba Obrumah , Odame Doreen Nyarko Anyamesem 
Published: September 2018

Purpose
The purpose of this paper is to assess the trends of socioeconomic-related inequalities in maternal healthcare utilization in Ghana between 2003 and 2014 and examine the causes of inequalities in maternal healthcare utilization in Ghana.

Design/methodology/approach
Data are drawn from three rounds of the Ghana Demographic and Health Survey collected in 2003, 2008 and 2014, respectively. The authors employ two alternative measures of socioeconomic inequalities in health – the Wagstaff and Erreygers indices – to examine the trends of socioeconomic inequalities in maternal healthcare utilization. The authors proceed to decompose the causes of inequalities in maternal healthcare by applying a recently developed generalized decomposition technique based on recentered influence function regressions.

Findings
The study finds substantial pro-rich inequalities in maternal healthcare utilization in Ghana. The degree of inequalities has been decreasing since 2003. The elimination of user fees for maternal healthcare has contributed to achieving equity and inclusion in utilization. The decomposition analysis reveals significant contributions of individual, household and locational characteristics to inequalities in maternal healthcare. The authors find that educational attainment, urban residence and challenges with physical access to healthcare facilities increase the socioeconomic gap in maternal healthcare utilization.

Originality/value
There is a need to target vulnerable women who are unlikely to utilize maternal healthcare services. In addition to the elimination of user fees, there is a need to reduce inequalities in the distribution and quality of maternal health services to achieve universal coverage in Ghana.
Through the eyes of an artist: consumption ethos and commercial art in Bengal
Authors: Datta Anisha 
Published: September 2018

Purpose
Through a critical reading of a twentieth-century Bengali artist’s autobiography, this paper aims to attempt to demonstrate how commercial art and the consumption ethos symbolized by that art represented an archetypal bhadralok insignia. A close examination of this insignia reveals how the dynamics of modern liberal values mediating through the colonial capitalist structure in relation to the regional particularities of Bengal opened up a new space of cosmopolitanism, where there is an attempt to reframe cultural practices in the light of a broader global history of interrogation, reason, change and emancipation.

Design/methodology/approach
This paper is a historical analysis of primary sources.

Findings
It was found that the bhadralok-led Bengal School of Art influenced commercial art of early postcolonial Bengal.

Research limitations/implications
The study is limited to the region of Bengal.

Originality/value
This paper makes contributions to one of the less-researched, but very important areas, of business history in India.

Authors: Mohd Thas Thaker Mohamed Asmy Bin 
Published: September 2018

PurposeThis paper aims to examine the behavioural intention of donors or crowd funders to use crowdfunding-waqf model (CWM), as this model is proposed to address the liquidity problem faced bywaqfinstitution in Malaysia.Design/methodology/approachThe primary data are collected from the survey administered to donors or crowd funders in Klang Valley and the analysis is conducted using Partial Least Squares (PLS). The model has validated its acceptance in the field by adopting the theory of Technology Acceptance Model (TAM).FindingsThis study has revealed that both the perceived usefulness and perceived easy to use are found to have a positive impact on the intention of donors or crowd funders in assistingwaqfinstitution to developwaqfland in Malaysia. Furthermore, perceived easy to use has a positive relationship and direct effect with perceived usefulness of crowd funders to use the CWM.Research limitations/implicationsThe variables that have been used based on TAM in this study are constantly in flux. There are other variables such as trust, social norm, orientations that might be affecting the adoption level of donors or crowd funders in Malaysia. In addition, the current study is covering only Klang Valley, Malaysia. Future research is nevertheless still required that incorporate other variables and extend the study to other states of Malaysia.Practical implicationsThe findings of this paper will providewaqfinstitution with an alternative source for raising capital to developwaqfasset. The present study also has implications for government and policy makers.Originality/valueTo the best of the author’s knowledge, no study has incorporated an element of crowdfunding to developwaqfland. Thus, the present study is relevant in extending the importance of crowdfunding as a source of financing forwaqfinstitutions in developingwaqfland.
Improving the joint strength of the friction stir spot welding of carbon steel and copper using the design of experiments method
Authors: Abdullah Isam Tareq , Hussein Sabah Khammass 
Published: September 2018

Purpose
The purpose of this paper is to optimize the welding parameters: rotating speed and plunging depth of carbon steel and pure copper joints using friction stir spot welding (FSSW) with the aid of the design of experiments (DOE) method.

Design/methodology/approach
Carbon steel and pure copper sheets were welded using the FSSW technique with a cylindrical tool and without a probe. The welding parameters were: rotating speed: 1,120, 1,400 and 1,800 RPM and plunging depth: 0.2 and 0.4 mm. The welding process was carried out both with and without pre-heating. The welded specimens were analyzed using a shear tensile test. A microstructural investigation at the optimum conditions was carried out. The results were analyzed and optimized using the statistical software Minitab and following the DOE method.

Findings
Pre-heating the sample and increasing the rotating speed and plunging depth increased the tensile shear force of the joint. The plunging depth has the biggest effect on the joint efficiency compared with the rotating speed. The optimum shear force (4,560 N) was found at 1,800 RPM, 0.4 mm plunge depth and with pre-heating. The welding parameters were modified so that the samples were welded at 1,800 RPM and at plunging depths of 0.45–1 mm in 0.05 mm steps. The optimized shear force was 5,400 N. The fractured samples exhibited two types of failure mode: interfacial and nugget pull-out.

Originality/value
For the first time, pure copper and carbon steel sheets were welded using FSSW and a tool without a probe with ideal joint efficiency (95 percent).

Acoustic and petrophysical properties of mechanically compacted overconsolidated sands: Part 2 – Rock physics modelling and applications
Authors: Narongsirikul Sirikarn , Mondol Nazmul Haque , Jahren Jens 
Published: September 2018

ABSTRACTPart one of this paper reported results from experimental compaction measurements of unconsolidated natural sand samples with different mineralogical compositions and textures. The experimental setup was designed with several cycles of stress loading and unloading applied to the samples. The setup was aimed to simulate a stress condition where sediments underwent episodes of compaction, uplift and erosion. P‐wave and S‐wave velocities and corresponding petrophysical (porosity and density) properties were reported. In this second part of the paper, rock physics modelling utilizing existing rock physics models to evaluate the model validity for measured data from part one were presented. The results show that a friable sand model, which was established for normally compacted sediments is also capable of describing overconsolidated sediments. The velocity–porosity data plotted along the friable sand lines not only describe sorting deterioration, as has been traditionally explained by other studies, but also variations in pre‐consolidation stress or degree of stress release. The deviation of the overconsolidated sands away from the normal compaction trend on the VP/VS and acoustic impedance space shows that various stress paths can be predicted on this domain when utilizing rock physics templates. Fluid saturation sensitivity is found to be lower in overconsolidated sands compared to normally consolidated sands. The sensitivity decreases with increasing pre‐consolidation stress. This means detectability for four‐dimensional fluid saturation changes can be affected if sediments were pre‐stressed and unloaded. Well log data from the Barents Sea show similar patterns to the experimental sand data. The findings allow the development of better rock physics diagnostics of unloaded sediments, and the understanding of expected 4D seismic response during time‐lapse seismic monitoring of uplifted basins. The studied outcomes also reveal an insight into the friable sand model that its diagnostic value is not only for describing sorting microtextures, but also pre‐consolidation stress history. The outcome extends the model application for pre‐consolidation stress estimation, for any unconsolidated sands experiencing similar unloading stress conditions to this study.
Fluid deficits during prolonged overnight fasting in young healthy adults
Authors: Danielsson Erik J. D. , Lejbman Ilja , Åkeson Jonas 
Published: September 2018

BackgroundOvernight fasting is often prolonged before scheduled surgery, and the extent of perioperative fluid replacement may influence outcome. In clinical practice, basic requirements are estimated at 1.2‐2.0 mL·kg−1·h−1, but there is little contemporary clinical data on what deficits result from complete fasting. This prospective preclinical study was designed to determine total fluid loss during overnight fasting, prolonged during daytime.MethodsTwenty (10 female) healthy adult volunteers, aged 24 (range 21‐46) years, fasted from 22:00 until 16:00, and had their body weight and urine output measured at predefined time intervals.ResultsThe median (interquartile range) fluid deficits were 0.82 (0.73‐1.00) kg, corresponding to 1.26 (1.11‐1.41) g·kg−1·h−1 for the initial overnight fasting period, 0.59 (0.40‐0.70) kg and 0.99 (0.83‐1.31) g·kg−1·h−1 for the consecutive daytime period, and 1.47 (1.27‐1.64) kg and 1.19 (1.05‐1.28) g·kg−1·h−1 for the total period of fasting. Urine output accounted for 52% of total weight loss and was 36% of the baseline hourly level during the last four‐hour period of fasting.ConclusionsTen hours of overnight fasting in young adults induces fluid deficits at the lower limit of estimated intervals referred to in clinical practice, and hourly weight loss gradually decreases further during prolonged daytime fasting. These findings indicate that current routine procedures do slightly overestimate fluid deficits resulting from prolonged fasting in perioperative clinical practice.

Published: September 2018

BackgroundIt is a common prejudice that anaesthetic doctors are believed to have high coffee consumption. In this study, we aimed to assess the association between coffee drinking and work satisfaction among Scandinavian anaesthesiologists. We hypothesised that coffee consumption was positively correlated with work satisfaction.MethodsWe invited anaesthesiologists attending the 34th congress of The Scandinavian Society of Anaesthesiology and Intensive Care Medicine in Malmö, Sweden, September 2017 to participate in a paper‐based survey. We collected data on characteristics of the respondents, coffee drinking and work satisfaction, and compared coffee vs non‐coffee drinkers with regard to work satisfaction scored on a modified Wong‐Baker Faces Pain Rating Scale (Visual Analogue Scale from 0 to 10).ResultsA total of 271 anaesthesiologists participated in the survey, of which 265 (97.7%) of the questionnaires contained valid data. Some 143 (54.0%) of the respondents were women, the median (interquartile range, IQR) age was 41.0 (35.0‐49.5) years, and 242 (91.3%) were coffee drinkers. Coffee drinkers consumed median 4.0 (IQR: 2.5‐5.0) cups of coffee daily. Overall work satisfaction was median 8 (IQR: 8‐9), with no difference between respondents drinking coffee and those who did not (median 8 (IQR: 8‐9) vs 8 (IQR: 8‐9), Wilcoxon rank sum test, P = 0.62). Also, we found no association between work satisfaction and the number of cups of coffee consumed daily (r2 = 0.005, P = 0.24).ConclusionIn this survey, we found high work satisfaction among Scandinavian anaesthesiologists, with no difference between coffee and non‐coffee drinkers.

Published: September 2018

AbstractMarijuana use, which is disproportionately prevalent among human immunodeficiency virus (HIV)‐infected persons, can alter activity in fronto‐parietal regions during cognitively demanding tasks. While HIV is also associated with altered neural activation, it is not known how marijuana may further affect brain function in this population. Our study examined the independent and additive effects of HIV infection and regular marijuana use on neural activation during a cognitive interference task. The sample included 93 adults who differed on marijuana (MJ) and HIV statuses (20 MJ+/HIV+, 19 MJ+/HIV‐, 29 MJ‐/HIV+, 25 MJ‐/HIV‐). Participants completed a counting Stroop task during a functional magnetic resonance imaging scan. Main and interactive effects on neural activation during interference versus neutral blocks were examined using a mixed‐effects analysis. The sample showed the expected Stroop effect for both speed and accuracy. There were main effects of MJ in the right and left inferior parietal lobules, with the left cluster extending into the posterior middle temporal gyrus and a main effect of HIV in the dorsal anterior cingulate cortex. There was an interaction in the left fronto‐insular cortex, such that the MJ+/HIV+ group had the largest increase in activation compared with other groups. Among MJ+, signal change in this cluster correlated positively with cumulative years of regular marijuana use. These results suggest that comorbid HIV and marijuana use is associated with complex neural alterations in multiple brain regions during cognitive interference. Follow‐up research is needed to determine how marijuana‐related characteristics may moderate HIV neurologic disease and impact real‐world functioning.

AbstractBackground and AimsCannabis use is common among people on opioid agonist treatment (OAT), causing concern for some care providers. However, there is limited and conflicting evidence on the impact of cannabis use on OAT outcomes. Given the critical role of retention in OAT in reducing opioid‐related morbidity and mortality, we aimed to estimate the association of at least daily cannabis use on the likelihood of retention in treatment among people initiating OAT. As a secondary aim we tested the impacts of less frequent cannabis use.DesignData were drawn from two community‐recruited prospective cohorts of people who use illicit drugs (PWUD). Participants were followed for a median of 81 months (interquartile range = 37–130).SettingVancouver, Canada.ParticipantsThis study comprised a total of 820 PWUD (57.8% men, 59.4% of Caucasian ethnicity, 32.2% HIV‐positive) initiating OAT between December 1996 and May 2016. The proportion of women was higher among HIV‐negative participants, with no other significant differences.MeasurementsThe primary outcome was retention in OAT, defined as remaining in OAT (methadone or buprenorphine/naloxone‐based) for two consecutive 6‐month follow‐up periods. The primary explanatory variable was cannabis use (at least daily versus less than daily) during the same 6‐month period. Confounders assessed included: socio‐demographic characteristics, substance use patterns and social–structural exposures.FindingsIn adjusted analysis, at least daily cannabis use was positively associated with retention in OAT [adjusted odds ratio (aOR) = 1.21, 95% confidence interval (CI) = 1.04–1.41]. Our secondary analysis showed that compared with non‐cannabis users, at least daily users had increased odds of retention in OAT (aOR = 1.20, 95% CI = 1.02–1.43), but not less than daily users (aOR = 1.00, 95% CI = 0.87–1.14).ConclusionsAmong people who use illicit drugs initiating opioid agonist treatment in Vancouver, at least daily cannabis use was associated with approximately 21% greater odds of retention in treatment compared with less than daily consumption.
