AbstractOBJECTIVETo develop a clinical prediction model for diagnosing mild stroke/transient ischemic attack (TIA) in first-contact patient settings. DESIGN: Retrospective study design utilizing logistic regression modeling of patient clinical symptoms collected from patient chart histories and referral data. SETTING: Regional fast-track TIA clinic on Vancouver Island, Canada, accepting referrals from emergency departments (ED) and general practice (GP). PARTICIPANTS: Model development: 4187 ED and GP referred patients from 2008–2011 who were assessed at the TIA clinic. Temporal hold-out validation: 1953 ED and GP referred patients from 2012–2013 assessed at the same clinic. OUTCOMES: Diagnosis of mild stroke/TIA by clinic neurologists. RESULTS: 123 candidate predictors were assessed using univariate feature selection for inclusion in the model, and culminated in the selection of 50 clinical features. Post-hoc investigation of the selected predictors revealed 12 clinically relevant interaction terms. Model performance on the temporal hold-out validation set achieved a sensitivity/specificity of 71.8% / 72.8% using the ROC01 cutpoint (≥ 0.662), and an AUC of 79.9% (95% CI, 77.9%–81.9%). In comparison, the ABCD2 score (≥ 4) achieved a sensitivity/specificity of 70.4% / 54.5% and an AUC of 67.5% (95% CI, 65.2%–69.9%). The logistic regression model demonstrated good calibration on the hold-out set (β0= −0.257); βlinear= 1.047).CONCLUSIONSThe developed diagnostic model performs better than the ABCD2 score at diagnosing mild stroke/TIA on the basis of clinical symptoms. The model has the potential to replace the use of the prognostic ABCD2 score in diagnostic medical contexts in which the ABCD2 score is currently used, such as patient triage.

There was a mix of conceptual/review papers and empirical studies, using both quantitative and qualitative methods.FindingsThe papers presented new directions on equality, diversity and inclusion research. Findings from exploratory papers indicated the need to develop an understanding of the notion of solidarity and the divisive and inclusive elements of the enactment of solidarity. Empirical studies reveal that women and people from black and minority ethnic communities continue to be excluded and marginalized, whereas there is a call for greater consideration of age in the social, economic, political and market arenas.Originality/valueThis report integrates unique insights on “Equality, Diversity and Inclusion and Human Rights in Times of Austerity”, as these were presented and discussed at the EDI 2016 Conference.
Serious games as a virtual training ground for relocation to a new healthcare facility
Authors: Merschbrock Christoph , Lassen Ann Karina , Tollnes Tor , Munkvold Bjørn Erik 
Published: November 2016

PurposeThis paper aims to enquire into how building information modelling (BIM) and gaming can be integrated to support professionals in their learning about the spatial layout of a new building. This knowledge is important to prepare building operation and facilities management (FM).Design/methodology/approachIngrained in task–technology fit theory, this paper reports from a case study of a serious game staged in the graphical environment of a building information model. A series of interviews with the client, subject-matter experts and software developers involved in developing the game were conducted. The industrial setting for the study is a major hospital construction project in Norway. The project has been awarded BuildingSMART’s 2015 award for “outstanding open BIM practice”, making it Norway’s role model for BIM practice.FindingsImporting and exporting geometry from BIM into a game engine remain challenging. The transfer of data between the two requires workarounds using intermediary software. Apart from issues related to technical interoperability, several sociotechnical challenges influential for the integration of BIM and gaming have been identified, related to: the collaboration among construction, operational and gaming experts; clear communication of information needs; and better contractual agreements.Research limitations/implicationsBIM’s geometric and semantic data enabled the creation of a sophisticated game for preparing building operation. Test-users perceived the game to be superior to classroom teaching for learning about the spatial layout of the building. However, quantifying the business value of the game for operation after occupancy of the new facilities was beyond the scope of this study.Originality/valueThe work presented exemplifies a novel application area of BIM and gaming technology in FM. The findings presented in this article are relevant for professionals and scholars seeking to expand the utility of BIM for starting up the operation of new facilities.
Organising in-house cleaning services in public FM
Authors: Klungseth Nora Johanne , Blakstad Siri Hunnes 
Published: November 2016

Purpose
This paper aims to describe and discuss in-house cleaning services in local authorities to gain a better understanding of current practices. These descriptions are intended to increase researchers’, practitioners’ and educators’ understanding of the studied issue, as there at present does not exist a solid understanding of in-house cleaning services in local authorities. Previous studies provide little detailed information regarding the internal environment of facility management (FM) organisations, in particular with regard to FM organisations’ individual services.

Design/methodology/approach
This research is based on two descriptive case studies, one from Norway and one from the UK. The case studies are based on semi-structured, face-to-face in-depth interviews and document reviews.

Findings
The cases demonstrate that in-house cleaning services can be structured and managed in different ways, particularly with respect to the split in services, the management of staff and customer contracts, the span of control, the chain of command, self-managed leadership, cleaners’ hours of duty and the use of outsourcing.

Research limitations/implications
Although the previous research on particular FM services is limited, this paper’s detailed descriptions may stimulate further development and research within the field. The knowledge brought forward is part of bridging a knowledge gap on cleaning in FM research. This knowledge can contribute to advancements in the way this service is discussed and measured across contexts by encouraging more rigour and specific studies on cleaning.

Originality/value
This paper constitutes one of the first detailed descriptions of in-house cleaning organisation in local authorities. This is a type of service supply that is common in certain contexts and identified as beneficial to cost-saving in other contexts.
Facilities management unit: improving self-image before its customers
Authors: Ogbeifun Edoghogho , Mbohwa Charles , Pretorius Jan-Harm C. 
Published: November 2016

Purpose
The purpose of this study is to explore the role of effective communication and the use of customer-friendly periodic report as tools for managing cordial relationship between facilities management (FM) operatives and their customers. FM functions require effective management of the relationships between the customers, workplace interface and support facilities, to facilitate the achievement of the objectives of the organisation. This suggests that FM operatives should continuously marry their performance priorities with the customers’ priorities and perception; otherwise, the FM operatives may be toiling without objective recognition of service or achieve improved customer satisfaction.

Design/methodology/approach
The case study method of qualitative research was adopted. The data were collected using the combination of in-depth interviews and evaluation of FM’s periodic reports from two universities in South Africa.

Findings
The FM units in both universities have a suitable operational system and use a modern computer-aided FM tool. However, the units have not been able to manage relationships with customers, largely because they have not been able to “deliver on promise” and have not learnt to use the soft skills of effective communication. The quality of the periodic reports from the units does not provide sufficient educative information for the end-users; the structure is not stakeholders-friendly.

Originality/value
The paper identifies that though FM units spend considerable time in the development, maintenance and effective running of support facilities, they pay little attention to documentation, reporting and use of the soft skills of effective communication, which are necessary ingredients for improved customer relationships.

The purpose of this paper is to propose a new stabilized finite volume element method for the Navier-Stokes problem.

Design/methodology/approach
This new method is based on the multiscale enrichment and uses the lowest equal order finite element pairs P1/P1.

Findings
The stability and convergence of the optimal order in H1-norm for velocity and L2-norm for pressure are obtained.

Originality/value
Using a dual problem for the Navier-Stokes problem, the convergence of the optimal order in L2-norm for the velocity is obtained. Finally, numerical example confirms the theory analysis and validates the effectiveness of this new method.
Darcy-Forchheimer flow with variable thermal conductivity and Cattaneo-Christov heat flux
Authors: Hayat T. , Muhammad Taseer , Al-Mezal Saleh , Liao S.J. 
Published: November 2016

Purpose
The objectives of present communication are threefolds. First is to model and analyze the two-dimensional Darcy-Forchheimer flow of Maxwell fluid induced by a stretching surface. Temperature-dependent thermal conductivity is taken into account. Second is to examine the heat transfer process through non-classical flux by Cattaneo-Christov theory. Third is to derive convergent homotopic solutions for velocity and temperature distributions. The paper aims to discuss these issues.

Design/methodology/approach
The resulting non-linear system is solved through the homotopy analysis method.

Findings
An increment in Deborah number β causes a reduction in velocity field f′(η) while opposite behavior is observed for temperature field θ(η). Velocity field f′(η) and thickness of momentum boundary layer are decreased when the authors enhance the values of porosity parameter λ while opposite behavior is noticed for temperature profile θ(η). Temperature field θ(η) is inversely proportional to the thermal relaxation parameter γ. The numerical values of temperature gradient at the sheet − θ′(0) are higher for larger values of thermal relaxation parameter γ.

Originality/value
To the best of author’s knowledge, no such consideration has been given in the literature yet.
Self-employment of men supported by female breadwinners
Authors: Gather Claudia , Schürmann Lena , Zipprian Heinz 
Published: November 2016

Purpose
This paper aims to look at the multiple embeddedness of male self-employment by focusing on entrepreneurship of men supported by female breadwinners.

Design/methodology/approach
Following a qualitative research design, the paper presents three case studies drawn from a research project, where 40 narrative interviews were conducted with female and male business starters.

Findings
The concept of embeddedness that was developed for female business founders can also be applied and specified for business startups of men. Creating and conducting a business or becoming self-employed is for men closely related to and interwoven with gender norms, household and partnership dynamics. Men who are not the family breadwinners benefit from the male connotations of entrepreneurship. Male self-employment, even if of precarious or low pecuniary relevance, allows them to fulfill the norms of masculinity and employment.

Research limitations/implications
Given that this is a qualitative study only based on three case studies, more research is needed to estimate the frequency of this type of male self-employment.

Originality/value
The importance of the context for the decision on starting-up and conducting a business is shown for male entrepreneurs. The study demonstrates how on the household level the male entrepreneurship norm is transformed into everyday lives and fits into gender arrangements. In emphasizing the non-economic dimensions of entrepreneurship, the paper opens the discussion about the interconnections between gender and entrepreneurship for men as well.
Gender, family and business
Authors: Guo Xuguang , Werner Jon M. 
Published: November 2016

Purpose
This paper aims to examine the relationship between family responsibilities and family support, on the one hand, and decisions by men and women concerning owning a business, as well as how many hours they work in that business.

Design/methodology/approach
The authors used data collected by the US Current Population Survey between 1989 and 2011 and had a starting sample of 1,258,430 individuals, and a final sample of 27,147.

Findings
The authors found that both women and men are more inclined to own a business when they are married, have children or receive financial support from their spouse. They also found widespread gender differences in these analyses. The influence of family-related issues on owning a business is stronger for women than for men.

Originality/value
The findings indicate that male business owners work longer hours if they have young children. In contrast, female business owners reduce their work hours if they are married, have young children and receive support from their spouse. Implications are discussed.
Study of the influence of lubrication parameters on gear lubrication properties and efficiency
Authors: Li Kaiyue , Chen Guoding , Liu Deng 
Published: November 2016

Purpose
The analysis of lubricating properties and efficiency is important for aviation high-speed gear. So far, the project of lubricating properties and efficiency are processing under the condition of a given lubricating state, which is still depending on practical experience. This paper aims to mostly focus on the analysis of given lubricating state but lost sight of the relevance of lubrication parameters and lubricating state, which not only makes the analysis of aviation high-speed gear transmission and efficiency fail to trace to practical situation but also has an adverse effect on the reliance and validity of the project.

Design/methodology/approach
Based on this, the numerical model of spraying oil and oil film spreading is established, and the quantitative relationship between spray lubrication parameters and spreading characteristics of oil film is studied. According to the geometric and mechanical conditions of meshing points and taking the influence of rich-oil/starved-oil lubrication and roughness of teeth surface into consideration, corrected film thickness under condition of elasto-hydrodynamic lubrication and lubricating state of mesh points are analyzed. On this basis, power consumption and efficiency of gear transmission are also calculated by figuring out the solid friction and oil friction separately.

Findings
Through the research of this thesis, the effect of friction power consumption and efficiency with lubrication parameters is discussed. The effect of lubrication parameters on friction power consumption and efficiency of gear is complex. With the increase of spreading film thickness and film length, the frictional power consumption is less and the efficiency is higher.

Originality/value
This work provides a systematic technological approach to lubrication design and efficiency calculation of aviation high-speed gear transmission, which has remarkable engineering significance for the accurate lubrication design of the aviation mechanical parts.
Effect of micropolar lubrication in non-circular hole-entry hybrid journal bearing with constant flow valve restrictor
Authors: Kumar Rajneesh , Verma Suresh 
Published: November 2016

PurposeIn the present scenario of high-speed machines, the use of non-circular hole-entry bearing configuration, i.e. two-lobe, multi-lobe, lemon bore, etc., has becomes unavoidable, as the journal bearings with non-circular configurations provide better stability at high operating speed and heavy dynamic loading. Further, this research aims to show that the presence of micro particles in the lubricants greatly affects performance of the bearings, as their presence leads to non-Newtonian behaviors of the lubricant. Therefore, to consider the effect of these micro particles, the lubricant is modeled as a micropolar lubricant. The present work analyzes the effect of these micropolar lubricants on the performance of hole-entry circular and non-circular (two-lobe) hybrid journal bearings compensated with constant flow valve restrictor and compares with that of Newtonian lubricants.Design/methodology/approachThe modified Reynolds equation governing the laminar flow of iso-viscous, incompressible micropolar lubricant in the clearance space of a journal bearing system has been solved using finite element method and appropriate boundary conditions. Further, a comparative analysis between circular and non-circular (two-lobe) hybrid journal bearing compensated with constant flow valve restrictor operating with Newtonian and micropolar lubricant has been presented.FindingsThe numerically simulated results reveal that the non-circular bearing configuration provides better performance vis-à-vis the circular bearing configuration. Further, the increase in the micropolar effect of the lubricant enhances the performance of circular and the non-circular bearing configurations compared with the Newtonian lubricant. Also, in the case of the non-circular bearing configuration with an offset factor (δ = 1.5), the bearing performance improved compared with (δ = 1.25).Originality/valueMany research studies have been done in the area of non-circular hybrid journal bearing with Newtonian lubricants with different types of restrictors, but the non-circular hole-entry constant flow valve-compensated hybrid journal bearing operating with the micropolar lubricant has not been analyzed. Therefore, in the present work, an effort has been made to fill this research gap.
Oil condition monitoring for HEMM – a case study
Authors: Kumar Ashwani , Ghosh Subrata Kumar 
Published: November 2016

Purpose
The paper aims to monitor the condition of heavy Earth-moving machines (HEMMs) used in open cast mines by lube oil analysis.

Design/methodology/approach
Oil samples at periodic interval were collected from the HEMM engine (Model No: BEML BH50M). Ferrography and Field Emission Scanning Electron Microscopy have been used for the wear particle analysis present in oil samples. Viscosity analysis and Fourier transform infrared spectroscopy have been done to investigate the degradation in quality and changes as compared to the initial structural properties of the lubricants.

Findings
The results obtained indicates wear in cylinder liner and piston ring. Copper, cast iron, alloy steel and ferrous oxide have been found as rubbing wear particles and cutting wear particles. Contamination level has also been found to be increasing in consecutive older oil samples. Chemical properties degraded with usage time and variations in oxidation and soot level have also been observed in every sample.

Practical implications
The results will be very much useful to maintenance teams of mining industry for early prediction of any impending failure of the machines, for example, diesel dilution, severe wear of the piston or cylinder liner leading to seizure can be predicted.

Originality/value
The HEMMs are an important piece of equipment in coal mining. Proper condition monitoring of HEMM is required to reduce the break down and down time to increase production.
Room temperature tribological performance of biodiesel (soybean oil)
Authors: Peng De-Xing 
Published: November 2016

Purpose
This paper aims to evaluate the effect of biodiesel additive in fuel system of diesel engines to reduce wear characteristics. Biofuels are environmentally friendly and renewable alternatives to mineral-based fuels and cause low pollution; thus, they can be used to comply with future emission regulations to safeguard environmental and human health.

Design/methodology/approach
Two types of diesel fuel, pure petrodiesel and soybean oil, were compared for their fuel properties and tribological performance. The ball-on-disk wear testing method was used as an analytical tool for this purpose. The lubricating efficiency of the fuels was estimated using a photomicroscope to measure the average diameter of the wear scar produced on the test ball.

Findings
The wear experiments showed that the wear scar diameters were 1.13 and 0.94 mm for lubrication of the pure petro-diesel and soybean oil, respectively. However, fatty acids containing biodiesel typically have thicker molecular layers than mineral pure petro-diesel, and thus can reduce the wear rate of the sliding metals. This improved the boundary lubrication conditions and the lubricity of the fuel. Biodiesel fuels are effective lubricity enhancers and have greater lubricity enhancing properties than petro-diesel.

Originality/value
The ability of biodiesel to be highly biodegradable and its superior lubricating property when used in compression ignition engines make it an excellent fuel. Biofuel is an attractive alternative fuel to various energy sectors, particularly the transportation sector. Biofuel has immense potential for use in a sustainable energy mixture in the future.
