Continuum approximations for lattice-free multi-species models of collective cell migration
Authors: Matsiaka Oleksii M , Penington Catherine J , Baker Ruth E , Simpson Matthew J 
Published: March 2017

AbstractCell migration within tissues involves the interaction of many cells from distinct subpopulations. In this work, we present a discrete model of collective cell migration where the motion of individual cells is driven by random forces, short range repulsion forces to mimic crowding, and longer range attraction forces to mimic adhesion. This discrete model can be used to simulate a population of cells that is composed ofK≥ 1 distinct subpopulations. To analyse the discrete model we formulate a hierarchy of moment equations that describe the spatial evolution of the density of agents, pairs of agents, triplets of agents, and so forth. To solve the hierarchy of moment equations we introduce two forms of closure: (i) the mean field approximation, which effectively assumes that the distributions of individual agents are independent; and (ii) a moment dynamics description that is based on the Kirkwood superposition approximation. The moment dynamics description provides an approximate way of incorporating spatial patterns, such as agent clustering, into the continuum description. Comparing the performance of the two continuum descriptions confirms that both perform well when adhesive forces are sufficiently weak. In contrast, the moment dynamics description outperforms the mean field model when adhesive forces are sufficiently large. This is a first attempt to provide an accurate continuum description of a lattice-free, multi-species model of collective cell migration.
Building operation and maintenance: manpower in Hong Kong
Authors: Lai Joseph H.K. 
Published: March 2017

Purpose
The study aims to reveal the state of building operation and maintenance (O&M) manpower in Hong Kong. In addition, the study included supply and demand of O&M practitioners, gaps between their required and possessed competences and ways to meet the manpower needs.

Design/methodology/approach
After developing a model that integrates manpower levels (L), trades (T) and natures (N) of O&M works (named as “LTN” model), a full spectrum of O&M jobs were established followed by collecting data of 75 organizations and 402 stakeholders through two surveys.

Findings
Besides the large O&M workforce, vacancy rates of the jobs were found to be significant. For the different trades and natures of O&M works, the knowledge/skills levels perceived by the stakeholders were lower than the corresponding importance levels.

Research limitations/implications
The methodology of the study can be used in future research for revealing the state of O&M manpower in Hong Kong and cities alike. The way in which the “LTN” model was developed may be used as a reference for constructing similar models for manpower research in other industries.

Practical implications
The findings and the measures for improving the O&M manpower can assist policymakers and human resources departments to formulate necessary education and training courses for the building industry.

Originality/value
The study is the first of its kind focusing on building O&M manpower. The state of the manpower it unveiled forms a basis for comparison with similar findings in future.
Modelling the relationship between green built environment and occupants’ productivity
Authors: Mallawaarachchi Harshini , De Silva Lalith , Rameezdeen Raufdeen 
Published: March 2017

Purpose
The purpose of the study presented in this paper is to determine the relationship and effect of built environment on occupants’ productivity in green-certified office buildings in Sri Lanka.

Design/methodology/approach
Two research hypotheses were tested by approaching the survey method under the quantitative phenomenon. The questionnaire survey was conducted among randomly selected occupants in three selected green-rated office buildings in Sri Lanka. The survey data were analysed by using the Spearman correlation and ordinal logistic regression analysis techniques to model the relationship existing between the variables. The SPSS v20 software was used in data analysis.

Findings
The findings confirm the relationship between built environment and occupants’ productivity. As it further proves that, there is a significant effect of built environment on occupants’ productivity in green-certified office buildings. Thus, critical built environment factors influencing occupants’ productivity and their effect were determined.

Practical implications
The findings could be practically implied as bases to strengthen the evaluation criteria of indoor environmental quality in GREENSL® national green-rating system.

Originality/value
The evaluation of occupants’ productivity and the built environment factors has been at the focal point of research; however, most studies have focused on single aspects of the built environment. Further, no evidences were found on “which factors” can critically influence the occupants’ productivity in green buildings. The paper, therefore, seeks to fill this gap by proving the relationship between green built environment and occupants’ productivity.
Taxpayers’ perceptions on tax evasion behaviour: an empirical study in Malaysia
Authors: Pui Yee Chan , Moorthy Krishna , Choo Keng Soon William 
Published: March 2017

Purpose
The success of self-assessment tax system is voluntary compliance with the tax laws. When tax evasion is seen as unacceptable, taxpayers will tend to evade tax less. Hence, the understanding of taxpayers’ attitude on tax morality towards a tax system has to be enhanced to minimize tax evasion cases. The purposes of this study are to examine the relationship between tax fairness, tax knowledge, enforcement level and social exchange towards taxpayers’ attitude of tax morality under the self-assessment system in Malaysia and also to identify the relationship between taxpayers’ attitude of tax morality and taxpayers’ perceptions on tax evasion.

Design/methodology/approach
Data were collected from 400 taxpayers through a questionnaire and analysed.

Findings
From the analysis, it has been found out that tax knowledge is the most important tax system characteristic that affects taxpayers’ attitude of tax morality. In addition, taxpayers’ attitude of tax morality is significant to taxpayers’ perceptions on tax evasion in Malaysia.

Originality/value
The findings of this study would be useful for the government to further improve the present tax system to increase voluntary tax compliance.
Consumer decision making when purchasing eco-friendly apparel
Authors: Rothenberg Lori , Matthews Delisia 
Published: March 2017

Purpose
The purpose of this paper is to identify the realistic trade-offs young consumers make when purchasing organic T-shirts.

Design/methodology/approach
A full profile discrete choice design was used. The data were analysed using a multinomial logit model and desirability indices.

Findings
Price was the most important attribute to consumers followed by the place of production and then sustainability. Consumers were most willing to purchase T-shirts that are eco-friendly, Made In America, made from wrinkle-free technology and cotton jersey knit fabric, and have a price of $15. Although consumers were most willing to pay $15, some were still willing to pay $25 or even $35 for the same eco-friendly T-shirt.

Practical implications
Consumers in the current study were more willing to purchase eco-friendly as opposed to organic apparel. The findings suggest that retailers need to consider the language used when communicating with consumers. Also, consumers were more willing to purchase T-shirts Made In America. Retailers may want to promote their domestic manufacturing through in-depth branding and promotions.

Originality/value
In order to identify the attributes to be used in the current study, labels on T-shirts in stores were examined and then those attributes were verified in the literature. In addition, the inclusion of price as an attribute, rather than as a separate independent question, provides a more realistic view of young consumers’ decision making.
Stability evaluation of three-layered journal bearing with slip/partial slip
Authors: Rao T.V.V.L.N. , Rani A.M.A. , Awang M. , Hashim F.M. 
Published: March 2017

Purpose
This paper aims to present stability of a three-layered journal bearing considering magnitude of the layers’ thicknesses and viscosities with slip/partial slip on the bearing surface.

Design/methodology/approach
Modified Reynolds equation based on one-dimensional analysis is derived for a three-layered journal bearing with slip/partial slip. Dynamic coefficients are derived based on infinitesimal perturbation method. Linearized stability analysis is presented taking into account slip/partial slip on bearing surface; thicknesses and viscosities of bearing surface layer; and core layer and journal surface layer.

Findings
Results of threshold speed and critical whirl frequency ratio coefficients (Cω, CΩ), stiffness (Kij for i = x,y) and damping (Bij for i = x, y) coefficients and threshold speed (ωs) and critical whirl frequency ratio (Ωs) are presented. The bearing surface is analyzed for slip (total surface with slip) and partial slip (partial surface with slip). The slip-on bearing surface reduces stability, while partial slip improves bearing stability. The threshold speed coefficient (Cω) decreases with slip on bearing surface. The threshold speed (ωs) and critical whirl frequency ratio (Ωs) are influenced by the variation of threshold speed coefficient (Cω) and critical whirl frequency ratio coefficient (CΩ), respectively. A three-layered journal bearing with partial slip and thick high viscosity bearing surface layer results in higher threshold speed coefficient and has a potential to improve stability of journal bearing. The analyses indicate that optimal angular extent of partial slip region (θs) enhances the stability of journal bearing.

Originality/value
The paper presents parametric study of stability coefficients (Cω and CΩ) and evaluation of threshold speed (ωs) and critical whirl frequency ratio (Ωs) of a three-layered journal bearing with slip/partial slip.
XPS characterization of tribo-layer formation on the steel lubricated with crude and epoxidized jatropha oil under boundary lubrication
Authors: Lubis Abdul Munir Hidayat Syah , Ariwahjoedi Bambang , Sudin Mustafar 
Published: March 2017

Purpose
This study aims to characterize the composition of the tribo-layer formed during sliding of steel in the presence of crude jatropha oil (CJO) and epoxidized jatropha oil (EJO) under boundary lubricant application.

Design/methodology/approach
CJO was obtained from a local market and used as received. EJO was obtained by epoxidation process with peroxyformic acid catalyzed by acidic ion exchange resin. The tribological test was conducted by the four ball method according to ASTM 4192. Wear scars generated on the lower balls were used to characterize the tribo-layer. Energy-dispersive X-ray and X-ray photo spectroscopy analysis were conducted to characterize the tribo-layer composition.

Findings
EJO shows a lower friction coefficient compared to CJO. Moreover, EJO also shows better wear preventive properties compared to CJO. The oxidation of CJO and EJO has lead chemisorption of the oil to steel surface to cause formation of protective layers for the steel surface. The layers were constructed from inorganic oxide in the form of iron oxides and silicon oxide together with organic layers in form of aldehyde, ketone and carboxylic acid. The formation and removal of this layer from rubbing sites are considered to affect wear-preventive and friction behaviour of steel lubricated with CJO and EJO.

Originality/value
This works highlights friction and anti-wear characteristics of CJO and EJO. This work also presents the composition of the tribo-layer that formed because of the sliding of steel lubricated with CJO and EJO. The method and result can be used for further investigation and development of lubricant.

Understand what your maintenance service partners value
Authors: Ali-Marttila Maaren , Marttonen-Arola Salla , Kärri Timo , Pekkarinen Olli , Saunila Minna 
Published: March 2017

Purpose
The purpose of this paper is to identify what is currently valued in maintenance services. The study first conceptualizes the value construct through an examination of its elements, including both financial and non-financial elements, and second provides insight into its actors’ (i.e. customer companies, service providers, equipment providers) attitudes toward value creation.

Design/methodology/approach
The study uses data collected from maintenance service professionals by an online survey. First an explorative factor analysis is conducted to examine the value construct. After this cluster analysis is conducted to define the actors.

Findings
The empirical findings suggest seven main elements that capture maintenance service value: relationship synergies, reliability of the service partner, development, availability, service solutions and problem solving ability, environment, health, safety and quality, and adaptability to suit different situations. Further analysis reveals that the actors can be divided into three main strategy types: basic, quality- and collaboration-oriented partners.

Originality/value
In previous studies the comprehensive nature of maintenance service value has received less attention, and the literature has focused on the technical and financial aspects. This paper provides a new conceptualization of the value creating elements, including also non-financial elements, and offers an integrated measure for the actors to identify the comprehensive value construct around maintenance services. In addition, the findings show that the actors in the field still have varying strategies when considering value creation. Communication and mutual understanding of the value creating elements are important so that right services are carried out and developed with the right partners.
Enabling nanotechnology entrepreneurship in a French context
Authors: Glaser Anna , Ben Slimane Sonia , Auplat Claire , Coeurderoy Régis 
Published: March 2017

Purpose
The purpose of this paper is to build a holistic theoretical framework of enabling factors contributing to the development of enterprise in nanotechnology-related industries, in a French context.

Design/methodology/approach
A systematic literature review methodology was adopted. The review used three gauges to identify enabling factors contributing to the development of enterprise in nanotechnology-related industries in a French context: first, it analysed the literature related to the development of nanotechnologies in a perspective of sustainability in a multidisciplinary stance (“Green view”). Second, it took a disciplinary stance by exploring academic journals in the field of entrepreneurship (“Entrepreneurship view”). Third, it studied the perspective of France (“French view”).

Findings
The main finding is that in spite of different approaches and sometimes seemingly conflicting stances, the three views converge on three enabling factors: the importance of knowledge sharing across boundaries, access to university scientists and facilities, and government intervention. However, each view also has its particularities: the “Green view” emphasizes the need for civil society inclusion, the “Entrepreneurship view” underlines the importance of early stage capital and entrepreneurial behaviour and the “French view” concentrates on the role of clusters.

Research limitations/implications
The paper provides a theoretical framework and a starting point for further work on entrepreneurial nanotechnology facilitation. Its findings constitute a benchmark which may be tested in empirical cases. The focus on the French context may be seen as a limitation but also as a source of interesting comparative work focussing on other national or regional contexts.

Practical implications
The paper shows that public policy is an important element in the nascent field of enterprise development for nano-based materials. It outlines how different contexts create different barriers to entrepreneurship, and it proposes recommendations to overcome some of these barriers.

Originality/value
In this paper, findings result from an exploration of the nanotechnology literature that focusses solely on nanotechnology data sets and not on mixed data sets. The use of three different gauges leads to the construction of a holistic theoretical framework that includes enabling factors as well as the types of barriers that entrepreneurs have to overcome to succeed.
Action learning: ripples within and beyond the set
Authors: Warwick Robert James , Palmer Adam , McCray Janet 
Published: March 2017

Purpose
This paper aims to explore the impact of action learning (AL) on an individual and an organisation, particularly the process by which each affected the other. The organisation is a UK National Health Service (NHS) Trust that includes two hospitals.

Design/methodology/approach
This is a single person case study involving a clinician, but the voice of an author can also be heard. It involves the experience of the individual as they experience AL as part of a leadership development programme leading to a postgraduate certificate. The authors explain their caution of the case study approach and in doing so offer their thoughts in how this paper could be read and impact on practice.

Findings
The authors show a process whereby an AL set participant moves from being confident about their project to one of uncertainty as the impact of the project ripples throughout the organisation. Through this process of unsettlement, the individual’s unnoticed assumptions are explored in ways that enable practical action to be taken. In doing so, the individual’s leadership and identity developed.

Research limitations/implications
This is a single person case study in one organisation, thus affecting wider generalisation.

Originality/value
This single case study contributes to the debate on critical AL and the use of AL in the NHS.
Working in a therapeutic community: exploring the impact on staff
Authors: Vyas Anisha , Spain Cathy , Rawlinson David 
Published: March 2017

Purpose
The purpose of this paper is to explore the impact working in a therapeutic community (TC) has on staff practice and personal development.

Design/methodology/approach
Eight female members of staff who work in the TC participated in semi-structured interviews. Interviews were recorded and transcribed. Thematic analysis was used.

Findings
The findings of this paper show three superordinate themes: confidence gained within TC; the staff impact of the intensity of TC; and staff value for specific TC principles.

Research limitations/implications
Limitations include researcher bias as both authors work in the TC and/or in the service. Reasonable adjustments were made in order to account for this.

Practical implications
Implications for future research include understanding and supporting the needs of staff and further exploration of the impact of staff working within TCs for people diagnosable with emotionally unstable personality disorders.

Originality/value
The research was carried out at one of the longest running TCs for people with emotional instability in the country. It offers a unique opportunity to garner the views of staff members with up to 27 years of experience. Findings may be of value to practitioners, administrators, policy makers and researchers interested in therapeutic communities.
Training for enabling environments
Authors: Lombardo Aldo , Haigh Rex 
Published: March 2017

Purpose
The purpose of this paper is to demonstrate the training value of a residential “enabling environments” (LLEE) workshop in relation to the Royal College of Psychiatrists’ (RCPsych) ten specified standards, as rated by workshop participants.

Design/methodology/approach
A 34 question yes/no/na questionnaire was drawn up, derived from the ten value-based standards and criteria which need to be met for the enabling environment (EE) award by the RCPsych’s Centre for Quality Improvement (Table AI). It was administered after six residential workshops, in Italy and UK, to 99 participants. Results were analysed for each of the six workshops, and for each of the ten standards, to show the degree to which participants recognised whether the standards were met.

Findings
High rates of positive responses were recorded with little variation across the six workshops sampled. Some standards and criteria showed higher levels of positive responses, and some showed slightly higher scores for “not applicable”.

Practical implications
Experiential Living-Learning Experience (LLE) workshops provide a valid training experience for those developing or working in EEs.

Social implications
Value-based standards can only be fully understood by direct experience of them, as verbal or written explanations fail to convey the psychological impact of the experience.

Originality/value
The questionnaire and its translation is the original work of AL. RH is the founder of LLE training workshops and the EE award.
The Paris Agreement – Protecting the Human Right to Health?
Authors: Dietzel Alix 
Published: March 2017

AbstractThe Paris Agreement was largely viewed as a resounding success by those who took part in its negotiation. This paper examines whether these claims hold up to closer scrutiny. More specifically, the paper will assess whether the Paris Agreement protects the human right to health. Considering that the widely celebrated 1.5°C target aims to protect present and future generations from the effects of climate change, which include substantial threats to human health, this is an especially pertinent area of study for climate justice theorists. Despite the threats climate change poses to human health, the subject of health has been somewhat neglected among climate justice scholars and policy makers alike. This paper illustrates that a focus on health can reveal much about the inadequacies of the Paris Agreement and multilateral climate change governance more widely. Unfolding in two parts, the paper first focuses on human health, explaining how this is threated by climate change and why a human rights based climate justice approach can highlight the importance of these threats and define what is morally required of policy makers. Part two of the paper turns to the assessment of the Paris Agreement, focusing on whether the policy makers who negotiated the Agreement have met these requirements. By briefly examining what has been promised in the Convention and what has been achieved under the Kyoto Protocol to date, the paper is able to assess whether the Paris Agreement represents a significant departure from the so far inadequate response to the climate change problem. It will be illustrated that although there has been a small step forward, the Paris Agreement cannot be said to represent a just response which protects the right to health of present and future generations.
