Sequence-based prediction of olfactory receptor responses
Authors: Chepurwar Shashank , Gupta Abhishek , Haddad Rafi , Gupta Nitin 
Published: June 2019

SummaryComputational prediction of how strongly an olfactory receptor responds to various odors can help in bridging the widening gap between the large number of receptors that have been sequenced and the small number of experiments measuring their responses. Previous efforts in this area have predicted the responses of a receptor to some odors, using the known responses of the same receptor to other odors. Here we present a method to predict the responses of a receptor without any known responses, by using available data about the responses of other conspecific receptors and their sequences. We applied this method to olfactory receptors in insects Drosophila melanogaster (both adult and larva) and Anopheles gambiae, and to mouse and human olfactory receptors. We found the predictions to be in significant agreement with the experimental measurements. The method also provides clues about the response-determining positions within the receptor sequences.

AbstractPurposeThis study provides insights into the individual sleep patterns and nocturnal cardiac autonomic activity responses of elite female soccer players during an international tournament.Materials and methodsTwenty elite female soccer players (aged 25.2±3.1 years) wore wrist actigraph units and heart rate (HR) monitors during night-sleep throughout 9 consecutive days (6 day-time training sessions [DT], 2 day-time matches [DM], and 1 evening-time match [EM]) of an international tournament. Training and match loads were monitored using the session-rating of perceived exertion (s-RPE) and wearable 18-Hz GPS (total distance covered [TD], training and match exposure time, and high-speed running [HSR]) to characterize training and match loads.ResultsIndividually, s-RPE, TD, exposure time, and HSR during training sessions ranged from 20 to 680 arbitrary units (AU), 892 to 5176 m, 20 to 76 min, and 80 to 1140 m, respectively. During matches, s-RPE, TD, exposure time, and HSR ranged from 149 to 876 AU, 2236 to 11210 m, 20 to 98 min, and 629 to 3213 m, respectively. Individually, players slept less than recommended (<7 hours) on several days of the tournament, especially after EM (n=8; TST ranging between 6:00-6:54 h). Total sleep time coefficient of variation (CV) ranged between 3.1 and 18.7%. However, all players presented good sleep quality (i.e., sleep efficiency ≥75%; individual range between: 75-98%) on each day of the tournament. Most of the players presented small fluctuations in nocturnal cardiac autonomic activity (individual nocturnal heart rate variability [HRV] ranged from 3.91-5.37 ms and HRV CV ranged from 2.8-9.0%), while two players presented higher HRV CV (11.5 and 11.7%; respectively).ConclusionOverall, elite female soccer players seemed to be highly resilient to training and match schedules and loads during a 9 day international tournament.

Head motion coefficient-based algorithm for distracted driving detection
Authors: Chui Kwok Tai , Alhalabi Wadee , Liu Ryan Wen 
Published: June 2019

Purpose
Concentration is the key to safer driving. Ideally, drivers should focus mainly on front views and side mirrors. Typical distractions are eating, drinking, cell phone use, using and searching things in car as well as looking at something outside the car. In this paper, distracted driving detection algorithm is targeting on nine scenarios nodding, head shaking, moving the head 45° to upper left and back to position, moving the head 45° to lower left and back to position, moving the head 45° to upper right and back to position, moving the head 45° to lower right and back to position, moving the head upward and back to position, head dropping down and blinking as fundamental elements for distracted events. The purpose of this paper is preliminary study these scenarios for the ideal distraction detection, the exact type of distraction.

Design/methodology/approach
The system consists of distraction detection module that processes video stream and compute motion coefficient to reinforce identification of distraction conditions of drivers. Motion coefficient of the video frames is computed which follows by the spike detection via statistical filtering.

Findings
The accuracy of head motion analyzer is given as 98.6 percent. With such satisfactory result, it is concluded that the distraction detection using light computation power algorithm is an appropriate direction and further work could be devoted on more scenarios as well as background light intensity and resolution of video frames.

Originality/value
The system aimed at detecting the distraction of the public transport driver. By providing instant response and timely warning, it can lower the road traffic accidents and casualties due to poor physical conditions. A low latency and lightweight head motion detector has been developed for online driver awareness monitoring.
High-quality relationships as antecedents of OCB: roles of identity freedom and gender
Authors: Singh Barjinder , Selvarajan T.T. , Chapa Olga 
Published: June 2019

PurposeThe purpose of this paper is to expand the criterion domain of organizational citizenship behaviors (OCBs), by examining the relationship between high-quality relationships (HQRs) and OCBs, with identity freedom as a mediator. In addition, the study also tries to highlight the role of gender as a moderator, whereby female (vs male) employees deferentially evaluate the importance of HQRs while engaging in OCBs.Design/methodology/approachThe authors conducted survey research by collecting data from 160 working adults and performed both basic mediation and mediated-moderated regression analysis with bootstrapping to determine the authors’ findings.FindingsResults of the study establish HQRs as important antecedents of employee citizenship behaviors, clarify the role of identity freedom as an important underlying psychological mechanism that mediates the relationship between HQRs and OCBs and position gender as an important boundary condition in the relationship between HQR and identity freedom, whereby female employees are more likely to enjoy identity freedom in the presence of HQRs, as opposed to males.Research limitations/implicationsThe present study illustrates the importance of HQRs and identity freedom as precursors of OCBs and in doing so expands the nomological net of OCBs, especially with respect to the antecedents of OCBs. The study also expands the scope of social identity theory by highlighting, in addition to social identity, the importance of identity expression.Practical implicationsThis study provides guidance to organizational practitioners to focus on building HQRs at work as HQRs, by making employees feel safe, pave the way for OCBs. In addition, the study also highlights the importance of gender as a moderator, whereby employees with different gender affiliations react differently to organizational contexts.Originality/valueVery little research has examined the relationship between HQRs and OCB. Antecedents of OCBs have been grouped into four categories: individual (or employee) characteristics, task characteristics, organizational characteristics and leadership behaviors. Clearly, the role played by the quality of interpersonal relationships in fostering OCBs has not been fully examined. By highlighting HQRs and identity freedom as antecedents of OCBs, the study informs the OCB literature by introducing interpersonal-relational and attitudinal elements as criterions of OCBs.
Muriel Pyrah: sources and myths from a West Riding of Yorkshire school, 1967–1972
Authors: Hoare Lottie 
Published: June 2019

Purpose
The purpose of this paper is to juxtapose different sources concerning educational experiments embarked on by an English primary school teacher, Muriel Pyrah. Pyrah taught at Airedale School, Castleford, Yorkshire, UK, from the 1950s until 1972. Her approach was celebrated in the fields of oracy and arts education in the final years of her working life. Airedale was a Local Education Authority (LEA) school within the West Riding of Yorkshire, an LEA led by Alec Clegg, from 1945 to 1974.

Design/methodology/approach
Using film footage, sound recordings, artwork and topic books produced by her pupils, the paper entangles these archival sources with recent interviews from Pyrah’s former pupils and a former school inspector (HMI). Pyrah’s actual name has been used, as has that of the HMI. The names of pupils who contributed insights are anonymised.

Findings
The former pupils provide accounts that encourage a move away from a revisiting of progressivism that is predominantly anchored in studying the intentions and hopes of high profile educationalists postwar.

Research limitations/implications
The number of former pupils willing to discuss their memories was small, so no claims are made that their perspectives represent the dominant views of former pupils. However, these interviews reveal details that are absent in the other surviving archival sources.

Originality/value
The paper lays the foundation for further research on the voices of former pupils, inviting a focus on the way those participants reflect on the long-term impact of being involved in an educational experiment. Thus far, the representation of Pyrah’s pedagogy has been choreographed in print to build the legacy of the LEA. The pupils’ stories resonate differently.
Numerical study of plume emission from an elevated line source in a wall-bounded flow
Authors: Noormohammadi Asghar , Wang Bing-Chen 
Published: June 2019

Purpose
This paper aims to study turbulent dispersion of a passive plume emitting from a single elevated line source of different elevations in a plane channel flow by using direct numerical simulation (DNS).

Design/methodology/approach
The investigation was conducted in both physical and spectral spaces, which includes an analysis of statistical moments and pre-multiplied spectra of the velocity and concentration fields. The pre-multiplied power spectra of the velocity and concentration fields are compared to identify the transition of the plume development from the turbulent convective stage to the turbulent diffusive stage.

Findings
It is observed that due to the presence of wall shear, the mean plume drifts toward the wall for the near-wall source release case. It is also observed that streamwise development of the plume is sensitive to both the source elevation and the downstream distance from the source. For the line source placed near the center of the channel, the plume development is dominated by the bulk meandering effects. However, for the plume emitting from the near-wall line source, it hits the ground soon after its release and becomes dominated by the wall shear. As the downstream distance from the line source increases, the streamwise development of the plume released from the near-wall line source transitions from a turbulent convective stage to a turbulent diffusive stage.

Originality/value
This paper represents an original DNS study of turbulent mixing and dispersion of a passive plume emitting from a line source of different elevations in a wall-bounded flow. This paper proposes a practical method to identify the transition of the plume development from the turbulent convective to the turbulent diffusive stages.

Authors: Mozaffari Masoud , D’Orazio Annunziata , Karimipour Arash , Abdollahi Ali , Safaei Mohammad Reza 
Published: June 2019

Purpose
The purpose of this paper is to improve the lattice Boltzmann method’s ability to simulate a microflow under constant heat flux.

Design/methodology/approach
Develop the thermal lattice Boltzmann method based on double population of hydrodynamic and thermal distribution functions.

Findings
The buoyancy forces, caused by gravity, can change the hydrodynamic properties of the flow. As a result, the gravity term was included in the Boltzmann equation as an external force, and the equations were rewritten under new conditions.

Originality/value
To the best of the authors’ knowledge, the current study is the first attempt to investigate mixed-convection heat transfer in an inclined microchannel in a slip flow regime.
An empirical approach to understanding the lower-middle and upper-middle income traps
Authors: Kabir M. Adnan , Ahmed Ashraf 
Published: June 2019

Purpose
The purpose of this paper is to investigate the factors that are significant in contributing to the per capita income growth of countries that are experiencing or have experienced the lower-middle and upper-middle income traps.

Design/methodology/approach
The study comprises 85 countries over the period 1960 to 2017 spanning across three income groups: lower-middle, upper-middle and high. A panel data structure was used to run a fixed effect and random effect estimation on three models of income groups. The Hausman specification test, which was used for further statistical fitness, confirmed the appropriateness of fixed effect over the random in explaining the estimation of factor variables.

Findings
The results show that unemployment is a pervasive problem that negatively affect countries at all income levels. Foreign direct investment and population of dependents are associated with economic progression of countries that have experienced or are experiencing the lower-middle income trap. Furthermore, rising income inequality and foreign aid assistance are detrimental to countries that have experienced or are experiencing the upper-middle income trap. Moreover, income inequality, disproportionate urban population and rising dependent population are damaging for high income countries that never experienced any of the middle-income traps. Conversely, openness to trade, inflation and exchange rate volatility had limited capacity in explaining growth dynamics.

Research limitations/implications
This study could not incorporate geopolitical, demographic, geographical and other such exogenous factors, which could have episodes of influences on the economic development of countries. These were outside the study's realm of quantitative analysis.

Originality/value
This paper contributes to existing literature by providing an empirical cross-sectional comparative analysis of countries belonging to different income groups. The prevailing literature lacks such a cross-tabulated presentation of factors affecting countries that avoided the middle income trap and those that could not.
Dimensions of knowledge governance in a multi-PMO project context
Authors: Martinez Sanz Maria Mercedes , Ortiz-Marcos Isabel 
Published: June 2019

Purpose
Knowledge is recognized to be a key asset to achieve the strategic objectives of an organization. To that end, it is necessary to count on governance mechanisms that ensure the alignment between the knowledge resources and processes and the business strategy. Given that knowledge management is often performed by project management offices (PMOs), the purpose of this paper is to explore if the dimensions for PMOs governance suggested in the literature are also valid for knowledge governance and what problems do exist.

Design/methodology/approach
This research has been done using case study methodology. A large complex project in the IT industry was deeply analyzed. This project brings together most of the elements that can be found in current organizational contexts (e.g. geographical dispersed project teams, multicultural environment, technical complexity, etc.), thus reinforcing the applicability of the results obtained.

Findings
The study findings indicate that knowledge flows between PMOs take place along the dimensions defined for PMO governance, thus confirming the suitability of those dimensions also for the governance of knowledge. This research also validates the connection between the barriers to knowledge sharing and the knowledge governance mechanisms, and provides empirical evidence of the importance of informal knowledge governance to foster knowledge sharing behaviors. This is of key importance to overcome daily operational issues. The observations made are, in fact, valuable lessons learnt for future projects and a valuable input for further research.

Originality/value
This study explores the similarities between PMOs governance and knowledge governance in multi-PMO settings on the basis of a case study, thus contributing additional empirical data to the literature. Previous work with this approach has not been found.
Patients’ intent to revisit with trust as the mediating role: lessons from Penang Malaysia
Authors: Mohd Isa Salmi , Lim Grace Sze Sze , Chin Phaik Nie 
Published: June 2019

Purpose
This study aims to examine hospital image, perceived medical quality, relationship marketing and word-of-mouth as the determinants of patients’ intent to revisit private hospitals in Penang, based on the theory of planned behaviour.

Design/methodology/approach
A quantitative study comprising a self-administered questionnaire was distributed to domestic and international patients at the airport, private hospitals and hotels located in Penang. The partial least squares structural equation modelling (PLS-SEM) approach was used to analyse and test the research hypotheses.

Findings
The results show that cognitive components (i.e. hospital image and perceived medical quality) do not have any significant influence on patients’ intent to revisit, while affective components (i.e. relationship marketing) and behavioural components (i.e. word-of-mouth) are important in increasing patients’ intent to revisit private hospitals in Penang, Malaysia. Trust has no significant mediating effect between predictor variables and patients’ intent to revisit, but it has significant association with affective and behavioural components.

Practical implications
The findings provide insights to medical marketing teams in promoting and increasing patients’ intent to revisit their respective hospitals and for the governments to sustain and enhance medical tourism in their countries.

Originality/value
This study is one of the few studies that looks at the relationship between hospital image, perceived medical quality, relationship marketing, word-of-mouth and patients’ intent to revisit private hospitals in Penang, Malaysia. This study also explored the direct and indirect effects of trust on patients’ intent to revisit that was still limited.
Optimization of process parameters of wire electro discharge machining for Ti49.4Ni50.6 shape memory alloys using the Taguchi technique
Authors: Takale Adik , Chougule Nagesh 
Published: June 2019

Purpose
Ti49.4Ni50.6 (at. %) shape memory alloy (SMA) is a unique class of smart materials because of unbeatable property which given a wide variety of their applications across a broad range of fields including an orthopedic implant. It plays a very important role in the constructions of novel orthopedic implants application (like dynamic compression plate) because of lower Young’s modulus compared to other biomedical implant materials, high mechanical strength, excellent corrosion resistance and unique property like shape memory effect. Conventional machining of Ti-Ni yields poor surface finish and low dimensional accuracy of the machined components. Hence, wire electro-discharge machining (WDEM) of Ti-Ni has been performed. The purpose of this paper is to investigate the effect of variation of five process parameters, namely, a pulse-on time, pulse-off time, spark gap set voltage (SV), wire feed and wire tension on the material removal rate, surface roughness (SR), kerf width (KW) and dimensional deviation (DD), in the WDEM of Ti49.5Ni50.6 SMA.

Design/methodology/approach
The effect of machining parameters on Ti49.4Ni50.6 has been fully explored using WEDM with zinc coated brass wire as an electrode. In this work, L18 orthogonal array based on Taguchi method has been used to conduct a series of experiments and statically evaluate the experimental data by the use of the method of analysis of variance. Scanning electron microscope images of the machined surface, at the highest and lowest pulse-on time, have been taken to evaluate the quality of surface in terms of their SR values.

Findings
For the highest pulse-on time, it is observed that blow holes, cracks, melted droplets and craters have been formed on the machined surface with an SR of 2.744 µm, while for the lowest pulse-on time, these are not formed with an SR of 0.862 µm. It is seen that the pulse-on time is the most significant process parameter for MRR, SR and KW, while the DD is significantly affected by spark gap SV. The optimal values of the process parameters have been obtained by the method of analysis of mean and the confirmatory experiments have been carried out to validate results of optimization. Energy dispersive spectroscopy analysis of the machined surface of Ti49.4Ni50.6 has shown a certain amount of deposition of material on the machined surface.
