Building entrepreneurial potential abroad – exploring return migrant experience
Authors: Pauli Urban , Osowska Renata 
Published: December 2018

Purpose
The purpose of this paper is to examine how entrepreneurial potential is built abroad during the periods of EU economic migration and how this affects the entrepreneurial behaviour of individuals after returning to their home country.

Design/methodology/approach
A mixed-methods approach was employed via developing a structured interview discussion guide with open and closed questions centred around the topic of migration, reasons for starting a business and capital (e.g. human, financial, relational) gained abroad. The study covered 54 Polish return entrepreneurs identified through random purposive sampling.

Findings
The findings suggest an important role of migration on the decision to start a business as almost half of the respondents formulated a business idea during the migration. The capital gains affecting entrepreneurial potential development were mostly observed in terms of financial and human capital with relational capital only applied to a business idea. This may explain individual preferences to setting up a business when returning to the home country. Overall, the findings confirm the important role of economic migration in building the entrepreneurial potential of returnee entrepreneurs.

Originality/value
The study explores an alternative to the mainstream assumptions on migration by investigating entrepreneurial individuals, processes and practices that happen during reverse migration. Furthermore, by applying the resource-based view of the firm theory, this research expands the understanding of the inter-relationship between processes of economic migration and entrepreneurial potential development.
Achieving triple bottom line sustainability in supply chains
Authors: Miemczyk Joe , Luzzini Davide 
Published: December 2018

PurposeCompanies are increasingly challenged by sustainability-related supply chain risks. Research has developed linking supply chain sustainability priorities, practices and triple bottom line performance; however, risk is rarely included in these models. The purpose of this paper is to understand the link between sustainable supply chain strategies, practices and performance, and to test the importance of risk management practices in this relationship focusing on the product category level.Design/methodology/approachThe paper includes a survey of supply managers in four countries with 305 responses, with a focus on upstream supply chain strategies at the product category level.FindingsThe environmental and social sustainability strategies lead to sustainable supply sustainable performance, through focused practices in either area, but the effect on operational and cost performance is not significant. Social supply chain strategies positively impact environmental and cost performance when mediated by risk assessment practices.Originality/valueThis paper shows a more nuanced view of the impact of supply chain practices on the strategy–performance link. It is one of the first papers to empirically test the role of risk practices in sustainable supply chain management and emphasize the importance of alignment across the main dimensions of sustainability to achieve positive sustainable performance outcomes, but not necessarily cost and operational performance. Unlike other studies, social sustainability priorities may positively impact environmental and social performance and is linked to cost advantage when implemented with risk assessment practices.

Authors: Shimada Atsushi , Konomi Shin’ichi , Ogata Hiroaki 
Published: December 2018

Purpose
The purpose of this study is to propose a real-time lecture supporting system. The target of this study is on-site classrooms where teachers give lectures and a lot of students listen to teachers’ explanations, conduct exercises, etc.

Design/methodology/approach
The proposed system uses an e-learning system and an e-book system to collect teaching and learning activities from a teacher and students in real time. The collected data are immediately analyzed to provide feedback to the teacher just before the lecture starts and during the lecture. For example, the teacher can check which pages were well previewed and which pages were not previewed by students using the preview achievement graph. During the lecture, real-time analytics graphs are shown on the teacher’s PC. The teacher can easily grasp students’ status and whether or not students are following the teacher’s explanation.

Findings
Through the case study, the authors first confirmed the effectiveness of each tool developed in this study. Then, the authors conducted a large-scale experiment using a real-time analytics graph and investigated whether the proposed system could improve the teaching and learning in on-site classrooms. The results indicated that teachers could adjust the speed of their lecture based on the real-time feedback system, which also resulted in encouraging students to put bookmarks and highlights on keywords and sentences.

Originality/value
Real-time learning analytics enables teachers and students to enhance their teaching and learning during lectures. Teachers should start considering this new strategy to improve their lectures immediately.
Dynamic supplier selection approach for mining equipment company
Authors: Ahmad Md. Tanweer , Mondal Sandeep 
Published: December 2018

PurposeThis paper aims to address the supplier selection (SS) problem under dynamic business environments to optimize the procurement cost of spare-parts in the context of a mining equipment company (MEC). Practically, involved parameters’ value does not remain constant as planning periods due to fluctuation in the demand and their market dynamics. Therefore, dynamicity in the parameter is considered as an important factor when a company forms a responsive chain through most eligible suppliers with respect to planning periods. This area of study may be considered for their complexities to the approaches toward order-allocations with bi-products of unused and repair spare-parts.Design/methodology/approachAn integrated methodology of analytic hierarchy process (AHP) and mixed-integer non-linear programming (MILP) is implemented in the two stages during each planning periods. In the first stage, AHP is used to obtain the relative weights with respect to each spare-parts of each criterion and based on that, the ranking is evaluated in accordance with case considered. And in the second stage, MILP is formulated to find the allocations of each spare-part with two distinct approaches through Model-1 and Model-2 separately. Moreover, Model-1 and Model-2 are outlined based on the ranking and efficient parameters-value under cost, limited capacities, quality level and delay lead time respectively.FindingsThe ranking and their optimal order-allocation of potential suppliers are obtained during consecutive planning periods for both unused and repair spare-parts. Subsequently, sensitivity analysis is conducted to deduce the key nuggets with the comparison of Model-1 and Model-2 in the changing of capacity, demand and cost per spare-parts. From this analysis, it is found that suppliers who have optimal parameter settings would be better for order-allocations than ranking during the changing planning period.Practical implicationsThis paper points out the situation-specific approach for SS problem for a mining industry which often faces disruptive supplying environments. The managerial implication between ranking and parameters are highlighted through Model-1 and Model-2 by sensitivity analysis.Originality/valueIt provides useful directions for managers who are involved in the procurement of spare-parts in the mining environment. For this, suppliers are selected for order-allocation by using Model-1 and Model-2 in the dynamic business environment. The solvability of the model is presented using LINGO 17. Furthermore, the case company selected in this study can be extended to other sectors.

Published: December 2018

PurposeTo satisfy donors and reduce public procurement acquisition prices, Benin has implemented and amended its first public procurement code guided by top-down principles of good governance.Design/methodology/approachThis study aims to measure the impact of the code and its amendment on public procurement acquisition prices of health-care equipment from 1995 to 2010.FindingsA segmented linear regression analysis was performed using interrupted time-series data. The analysis shows that the code and its amendment did not reduce acquisition prices, indicating the limited impact of the code. The authors recommend the implementation of bottom-up processes in establishing the public procurement system, and the development of a reference pricelist of the most widely used health-care equipment, as possible solutions for improving the effectiveness of the code.

Published: December 2018

PurposeThe purpose of this paper is to study the impact of Joule heating on boundary layer flow and melting heat transfer of Prandtl fluid over a stretching sheet in the presence of fluid particles suspension. The transformed boundary layer equations are solved numerically by RKF-45 method. The influence of the non-dimensional parameters on velocity and temperature growths in the boundary layer region is analyzed in detail and the results are shown graphically. The results indicate that the larger estimation ofαandβreduces for both velocity and temperature profile. Further, the rate of heat transfer decreases by increasing melting parameter.Design/methodology/approachThe converted set of boundary layer equations is solved numerically by RKF-45 method. Obtained numerical results for flow and heat transfer characteristics are deliberated for various physical parameters. Furthermore, the skin friction coefficient and Nusselt number are also presented.FindingsIt is found that the heat transfer rates are advanced in the occurrence of non-linear radiation camper to linear radiation. Also, it is noticed that velocity profile increases by increasing Prandtl parameter but establishes opposite results for temperature profile.Originality/valueThe authors intend to analyze the boundary layer flow and melting heat transfer of a Prandtl fluid over a stretching surface in the presence of fluid particles suspension. The governing systems of partial differential equations have been transformed to a set of coupled ordinary differential equations by applying appropriate similarity transformations. The reduced equations are solved numerically. The pertinent parameters are discussed through graphs and plotted graphs. The present results are compared with the existing limiting solutions, showing good agreement with each other.

Published: December 2018

Purpose
Purpose of this study is to measure the Vitamin D status of healthy adults and to correlate with their lifestyle and feeding habits. Plasma 25-Hydroxyvitamin D (25(OH)D) is the most common marker of vitamin D status of an individual. Deficiency of vitamin D is defined as the serum level less than 20 ng/mL and insufficiency as 30 ng/mL which can be prevented.

Design/methodology/approach
Vitamin D status of healthy adults (n = 82), both male and females between the age of 18 – 50 years who were attending to the National Transport Authority, Kandy, Sri Lanka from February to March 2016, was measured and correlated with their lifestyle, feeding habits, etc.

Findings
The mean total serum D (25(OH)D in this study was 40.15 ± 3.74 nmol/l with the mean value of 42.8 ± 28.8 and 37.5 ± 16.6 for women and men, respectively. The serum calcium levels of both female and male were around 8 mg/dl and the serum total protein was 6.5 and 7 g/dl in women and men, respectively. The serum Vitamin D, calcium and total protein were not statistically significantly different between the sexes. In this study, 84 per cent of the total subjects were normocalcemic, and there was no signiﬁcant relationship between vitamin D levels and their calcium levels.

Research limitations/implications
This study demonstrates that there was no statistically significant correlation between the serum vitamin D with age, serum calcium or total proteins. The majority of participants who had exposure to the sunlight more than 30 mins/day had sufficient level of vitamin D and less than 30 min/day exposure had deficiency of vitamin D. Daily intake of multivitamin influenced vitamin D status of the study group.

Practical implications
These findings will implicate the importance of cultural, feed and social habits for the nutritional status of an individual.and there are no reported studies on vitamin D status with reference to the variation of life style.

Social implications
It is very important to investigate the factors affecting to the vitamin D status of a population as such, vitamin D insufficiency or deficiency can be prevented. In Sri Lanka, the population is consisting with many ethnic groups, different ethnic groups may find some nutritional problems according to their main cultural habits.

Originality/value
The objectives of this study are to evaluate the Vitamin D status in a group of healthy adults between 20 and 50 years in both men and women and to find out the correlation of their vitamin D status with their lifestyle and feeding habits, etc.
The bright side of indebtedness
Authors: Faldetta Guglielmo 
Published: December 2018

Purpose
The purpose of this paper is to show that indebtedness can have a positive meaning for people who are embedded in social relationships in organizations if it is meant in the light of the notion of gratitude, gift-giving and generalized reciprocity.

Design/methodology/approach
The study reviews the literature on the common notion of indebtedness and integrates it with the literature on gratitude, gift-giving and generalized reciprocity.

Findings
The study reveals that through the notion of gratitude, gift-giving and generalized reciprocity people may conceive their indebtedness as gratitude for having received something, so triggering giving behaviors that does not necessarily aim to repay the debt, but to develop and feed their social relationships.

Originality/value
In the past indebtedness has been conceived as a negative feeling. This study reveals that it may have also a bright side when it is applied to people in flesh and bones, as they are immersed in good quality social relationships.

Impact of three‐dimensional attitude variations of an unmanned aerial vehicle magnetometry system on magnetic data quality
Authors: Walter Callum A. , Braun A. , Fotopoulos G. 
Published: December 2018

ABSTRACTOptically pumped vapour magnetometers have an orientation dependency in measuring the scalar component of the ambient magnetic field which leads to challenges for integration with mobile platforms. Quantifying the three‐dimensional attitude variations (yaw, pitch and roll) of an optically pumped vapour magnetometer, while in‐flight and suspended underneath a rotary unmanned aerial vehicle, aids in the successful development of reliable, high‐resolution unmanned aerial vehicle magnetometry surveys. This study investigates the in‐flight three‐dimensional attitude characteristics of a GEM Systems Inc. GSMP‐35U potassium vapour magnetometer suspended 3 m underneath a Dà‐Jiāng Innovations S900 multi‐rotor unmanned aerial vehicle. A series of unmanned aerial vehicle‐borne attitude surveys quantified the three‐dimensional attitude variations that a simulated magnetometer payload experienced while freely (or semi‐rigidly) suspended underneath the unmanned aerial vehicle in fair weather. Analysis of the compiled yaw, pitch and roll data resulted in the design of a specialized semi‐rigid magnetometer mount, implemented to limit magnetometer rotation about the yaw axis. A subsequent unmanned aerial vehicle‐borne magnetic survey applying this specialized mount resulted in more than 99% of gathered GSMP‐35U magnetic data being within industry standards. Overall, this study validates that maintaining magnetometer attitude variations within quantified limits (±5° yaw, ±10° pitch and roll) during flight can yield reliable, continuous and high‐resolution unmanned aerial vehicle‐borne magnetic measurements.
Class‐based masculinity, cardiovascular health and rehabilitation
Authors: Taylor Smith Adam , Dumas Alex 
Published: December 2018

AbstractMen in economically advanced societies are more at‐risk of dying prematurely due to heart disease than women, and this risk is inversely related to their socioeconomic status (SES). While the strong influence of socioeconomic factors on self‐management of chronic diseases is important, the impact of masculinity must also be considered. This study examines the social variation in preventive health lifestyles of men from two contrasting socioeconomic groups who have suffered from a cardiovascular incident requiring hospitalization. It draws chiefly on Pierre Bourdieu's sociocultural theory of the practice (habitus and symbolic violence). Qualitative data was collected through 60 in‐depth, semi‐structured interviews with Canadian men (average age 57.3). Results indicate that participants from both socioeconomic groups share aspirations towards personal fulfilment (achieving a sense of security, preserving autonomy and gaining social recognition) after their heart incident, but apply different strategies in pursuit of these aspirations that have distinctive effects on healthy lifestyles. This study emphasise the importance of drawing on theoretical approaches in public health that have the potential to combine universal with context‐specific views of human experience in order further understand health and lifestyle inequalities.
Incentives to move up: Effects of pay gaps between levels on employee performance
Authors: Chi Wei , Liao Hui , Wang Lei , Zhao Rui , Ye Qing 
Published: December 2018

AbstractEmployees of a certain rank are motivated by the pay gap between them and the levels above (upward comparison), and the pay gap between them and the levels below (downward comparison). In some cases, employees face multiple upward comparisons such as immediate and subsequent upward comparisons. We hypothesise that upward comparison matters more than downward comparison, and in the case of multiple upward comparisons, the immediate one matters more than the subsequent ones. We also hypothesise that the pay gap effect resulting from the upward/downward comparison ought to be non‐linear in that performance increases with pay gap size at a decreasing rate. The results from two empirical studies, namely, a longitudinal field study and a laboratory experiment, largely support our hypotheses.

Published: December 2018

ObjectiveMethotrexate (MTX) can be used as an alternative for patients with Crohn’s disease (CD) who are intolerant of thiopurine. This retrospective study aimed to provide some clues about MTX treatment in Chinese patients with CD.MethodsMedical records of 27 adult patients with CD who were treated with MTX between 2012 and 2017 at Renji Hospital were reviewed. MTX was administered at 15 mg or 20 mg intramuscularly once per week. The remission and response rates and adverse reactions of MTX were recorded and analyzed.ResultsThirteen (48.1%) of the patients achieved remission for more than 12 months, whereas four (14.8%) responded clinically. Eight (29.6%) patients discontinued MTX due to adverse events. The mean age of those who maintained remission was significantly younger than that of those who did not ([35.62 ± 10.99] years vs. [45.43 ± 11.93] years, P < 0.05). The pretreatment C‐reactive protein (CRP) level was higher in the group who maintained remission than that in those who did not ([17.20 ± 17.26] mg/L vs. [6.98 ± 5.66] mg/L, P < 0.05).ConclusionsMTX is effective and relatively safe for patients at doses of 15 mg/week or 20 mg/week and may be an alternative therapy for patients who are intolerant of thiopurine. Elderly patients with CD and patients with normal pretreatment CRP level may have a reduced response to MTX.
