Taking the strain: quantifying the contributions of all cell behaviours to changes in epithelial shape
Authors: Blanchard Guy B. 
Published: March 2017

Computer-assisted tracking of the shapes of many cells over long periods of development has driven the exploration of novel ways to quantify the contributions of different cell behaviours to morphogenesis. A handful of similar methods have now been published that are used to calculate tissue deformations (strain rates) in epithelia. These methods are further used to quantify strain rates attributable to each of the cell behaviours in the tissue, such as cell shape change, cell rearrangement and cell division, that together sum to the tissue strain rates. In this review, aimed at developmental biologists, I will introduce the general approach, characterize differences in current approaches and highlight extensions of these methods that remain to be fully explored. The methods will make a major contribution to the emerging field of tissue mechanics. Precisely quantified strain rates are an essential first step towards exploring constitutive equations relating stress to strain via tissue mechanical properties.This article is part of the themed issue ‘Systems morphodynamics: understanding the development of tissue hardware’.
A simple thermodynamic model on the cracking of concrete due to rust formed after casting
Authors: Sánchez-Deza Agustín , Bastidas David M. , La Iglesia Angel , Bastidas Jose-María 
Published: March 2017

Purpose
The purpose of this study is to use thermodynamic data to estimate the pressure exerted by the crystallization of iron oxyhydroxides following the equation proposed by Correns and Steinborn.

Design/methodology/approach
Standard free energy and molar volume data have been considered for goethite, lepidocrocite, magnetite and hematite, which are described in the literature as the most commonly found mineral phase rust constituents.

Findings
The studied mineral phases generate higher to lower crystallization pressure values in the following order: goethite > lepidocrocite > hematite > magnetite. The crystallization pressures calculated for these phases are in the 32-350 MPa range, which is higher than the tensile strength of concrete (of the order of 0.2-10 MPa) and thus leads to failure of the cover concrete.

Originality/value
The aim of this paper is to shed light on this issue by calculating the stresses generated by the crystallization of iron oxide from a supersaturated solution using thermodynamic data. A deliberately simplistic method was proposed, taking as reference the Correns–Steinborn model (Correns and Steinborn, 1939; Correns, 1949). The crystalline phases considered in this paper are those most commonly found in the literature as rust constituents, that is, goethite (α-FeOOH), lepidocrocite (γ-FeOOH), magnetite (Fe3O4) and hematite (α-Fe2O3). The FeO synthetic phase was also included as a reference.
Aerodynamic parameter identification of hypersonic vehicle via Pigeon-inspired optimization
Authors: Xue Qiang , Haibin Duan 
Published: March 2017

Purpose
The purpose of this paper is to propose a new approach for aerodynamic parameter identification of hypersonic vehicles, which is based on Pigeon-inspired optimization (PIO) algorithm, with the objective of overcoming the disadvantages of traditional methods based on gradient such as New Raphson method, especially in noisy environment.

Design/methodology/approach
The model of hypersonic vehicles and PIO algorithm is established for aerodynamic parameter identification. Using the idea, identification problem will be converted into the optimization problem.

Findings
A new swarm optimization method, PIO algorithm is applied in this identification process. Experimental results demonstrated the robustness and effectiveness of the proposed method: it can guarantee accurate identification results in noisy environment without fussy calculation of sensitivity.

Practical implications
The new method developed in this paper can be easily applied to solve complex optimization problems when some traditional method is failed, and can afford the accurate hypersonic parameter for control rate design of hypersonic vehicles.

Originality/value
In this paper, the authors converted this identification problem into the optimization problem using the new swarm optimization method – PIO. This new approach is proved to be reasonable through simulation.
Hypersonic dynamic stability of wave riders
Authors: Khalid Mahmood , Juhany Khalid A. 
Published: March 2017

Purpose
The purpose of this paper is to obtain close form expressions for the dynamic stability of conical wave riders with flat surfaces which could be equipped with lifting surfaces on its plain flat surface. Numerical simulation would require very large meshes to resolve flows at subscale level and the experimental evaluations would be equally difficult, requiring expensive measurement facilities with challenging procedures to secure such vehicles in confined test sections to obtain satisfactory wind on and wind off oscillations.

Design/methodology/approach
The design method uses appropriate pressure fields using small disturbance theory, which, in turn, is perturbed using the unsteady shock expansion theory to recover suitable expressions for the dynamic stability behaviour.

Findings
It was observed that the dynamic stability of the standard half-cone-type wave riders with flat upper surfaces deteriorates with the axis position measured from the pointed apex reaching a minimum at around x/co = 0.666. The half-cone wave rider with flat upper surfaces is dynamically less stable than a pure cone.

Research limitations/implications
The method is typically less accurate when the similarity parameter M∞θ ≤ 1 = 1 or if the angle of attack is not small.

Practical implications
With renewed interest in hypersonic, future hypersonically would be designed as fast lifting bodies whose shapes would be close to the configurations of hypersonic wave riders, especially if they are designed to operate at upper atmosphere altitudes.

Originality/value
The analytic approach outlined in this paper for the evaluation of dynamic and static stability derivatives is original, drawing from the strengths of the small disturbance theory and shock expansion techniques. The method is particularly important, as there are no reported theoretical, numerical or experimental results in the literature.
Empty truck trips problem at container terminals
Authors: Islam Samsul 
Published: March 2017

PurposeThe purpose of this paper is to explore, through a synthesis of the literature, the causes, benefits, constraints and ways for reducing the number of empty trips made by container trucks. Reduced empty truck trips contribute to sustainable transportation practices in the port territory.Design/methodology/approachTo contribute in the current body of the literature, through a comprehensive synthesis of the studies, this study examines many perspectives surrounding the empty truck trips at container terminals. Hence different, but relevant operational aspects of empty truck trips are explored. This study adopts a content analysis as the research methodology.FindingsDifferent perspectives, which are drawn from the reviewed literature, identify a research gap in published research in the area of transport collaboration (of supply chain collaboration) and coordination problems in hinterland transport chains (of maritime logistics), and the literature relating to backhauling (of vehicle routing problems with backhauls). To cover that research gap in the literature, this study attempts to highlight and synthesize the important empty-trips studies currently available into a coherent and understandable form.Practical implicationsAs an integral part of encouraging collaboration in the container transportation industry, this research may be effective in persuading port authorities to evaluate and to help transport managers to reply to specific enquiries of truck-sharing arrangements.Social implicationsThe utilization of available empty space of container trucks is a feasible option of increasing transport capacity and achieving sustainable transportation benefits.Originality/valueThis paper provides a contemporary lens to view the relationship between empty trips and their applications in the carrier industry, in order to resolve the perceived issues of non-sustainable transportation and their implications for the society.
Beamless or beam-supported building floors
Authors: Jarkas Abdulaziz M. 
Published: March 2017

Purpose
Due to a dearth of quantitative research into buildability factors affecting formwork labour productivity of in situ reinforced concrete construction, the purpose of this paper is to establish a distinct point of departure from the prevalent qualitative trend of buildability research practices by exploring, quantifying and comparing the influence of the two widely used design schemes; namely, beamless and beam-supported building floors, on formwork labour productivity.

Design/methodology/approach
A considerable quantity of relevant formwork labour productivity data associated with each building floor configuration was collected from projects sharing similar characteristics. The data were analysed to determine the statistical significance of the difference between the two labour productivity “means” of the sample sets representing both populations. Regression analyses were further carried out to assess the impact of floor area on labour efficiency.

Findings
The results obtained show a statistically significant difference between the two means of formwork labour productivity achieved, where the efficiency of “forming” the beam-supported floor type is, on average, lower by 57 per cent than that of the beamless configuration. The outcomes further demonstrate a significant influence of building floor area on the productivity of the form-working operation.

Practical implications
The findings can provide designers with feedback on how well their decisions consider the requirements of buildability principles, and the consequences thereto on labour productivity. The depicted pattern of results may, moreover, provide guidance to estimators and project managers for reasonable cost estimation, effective planning and efficient labour utilisation.

Originality/value
The general guidelines available for buildability improvement lack the supporting quantitative evidence, and thus are often viewed with scepticism, especially amongst design practitioners. On the contrary, the quantitative outcomes reported in this study are based on rigorous methodology, hence can be used as a supporting reference to “formalise” the specific buildability knowledge of the activity explored.
The influence of culture on trust in B2B banking relationships
Authors: Houjeir Roudaina , Brennan Ross 
Published: March 2017

Purpose
The purpose of this paper is to explore the significance of culture generally, and Arab culture in particular, for the development of trust in business-to-business (B2B) banking relationships.

Design/methodology/approach
Qualitative fieldwork was employed, gathering in-depth interview data from bankers and their business clients in the United Arab Emirates (UAE). In total, 80 relationships between bankers and business clients were investigated.

Findings
The development of trusting relationships between bankers and clients is affected by the cultural origins of the relationship partners. Strongly held religious beliefs, and loyalty to family, tribe and nation, lead to strong affect-based trust between bankers and clients from Arab culture. Cognitive-based trust is more characteristic of UAE banker/client relationships that involve partners from outside the Arab world.

Research limitations/implications
The study was conducted in the UAE. Additional tests in other Arab countries would be valuable. The qualitative nature of the study means that statistical generalizations cannot be drawn.

Practical implications
The cultural origins of banking relationship managers are of considerable importance when seeking to develop relationships of trust with business banking clients in the Arab world.

Originality/value
This substantial, qualitative study of banker relationships with business clients throws considerable light on the importance of culture as an antecedent to trust in B2B banking relationships.
A mixed methods empirical exploration of UK consumer perceptions of trust, risk and usefulness of mobile payments
Authors: Hampshire Chris 
Published: March 2017

Purpose
The purpose of this paper is to explore UK consumer perceptions of trust, risk and perceived usefulness of mobile payments through the use of sequential mixed methods.

Design/methodology/approach
A post-positivist philosophy is used with a social constructionist ontology with a questionnaire as the first survey instrument using an empirical sequential mixed methods approach. Summary quantitative analysis of the questionnaire data is undertaken followed by semi-structured interviews that produce qualitative data on which content analysis is undertaken to assess and explore UK consumer perspectives. The technology acceptance model is used as the underlying framework on which a conceptual model is developed.

Findings
UK consumers have significant risk and trust concerns with mobile payments, although these concerns can be overcome when clear consumer benefits are identified whilst bank supported mobile payments have an increased level of trust compared to new market entrants and other established companies. Furthermore, perceived trust positively influences perceived usefulness and mitigates perceived risk, whilst perceived risk negatively influences perceived usefulness. In addition, perceived usefulness significantly and positively influences UK consumer attitude which can lead to adoption.

Research limitations/implications
Whilst 120 completed questionnaire responses are received, only 101 questionnaires are used for analysis. In addition, ten semi-structured interviews are undertaken using a purposeful sample to minimise any imbalance (Oakley, 1981) which increases the reliability of the research findings (Hackley, 2003). This mobile payments research does not have a statistically secure universalisation of the findings, which negates the application of these research findings to other groups and to different social settings (Lincoln and Guba, 1985).

Practical implications
Mobile payment organisations will need to focus on identifying the specific benefits of mobile payments to UK consumers as mitigating risk and increasing trust do not compensate for the absence of usefulness.

Social implications
UK consumers indicate a lack of awareness of existing contactless payment guarantees provided by UK banks, although these payment guarantees significantly increase UK consumer trust.

Originality/value
Both quantitative and qualitative empirical data are obtained on UK consumer perspectives of risk, trust and perceived usefulness of mobile payments using sequential mixed methods.
Healthcare seeking behaviour among Chinese elderly
Authors: Lu Hui , Wang Wei , Xu Ling , Li Zhenhong , Ding Yan , Zhang Jian , Yan Fei 
Published: March 2017

Purpose
The Chinese population is rapidly ageing before they are rich. The purpose of this paper is to describe healthcare seeking behaviour and the critical factors associated with healthcare seeking behaviour.

Design/methodology/approach
Using a purposive sampling method, the authors recruited 44 adults aged 60 years or older from three provinces, representing the developed (Shanghai), undeveloped (Ningxia) regions and the regions in between (Hubei). From July to September 2008, using a semi-structured guide, the authors interviewed participants in focus group discussions.

Findings
The healthcare needs for chronic and catastrophic diseases were high; however, the healthcare demands were low and healthcare utilizations were even lower owing to the limited accessibility to healthcare services, particularly, in underdeveloped rural areas. “Too expensive to see a doctor” was a prime complaint, explaining substantial discrepancies between healthcare needs, demands and use. Care seeking behaviour varied depending on insurance availability, perceived performance, particularly hospital services, and prescription medications. Participants consistently rated increasing healthcare accessibility as a high priority, including offering financial aid, and improving service convenience. Improving social security fairness was the first on the elderly’s wish list.

Originality/value
Healthcare demand and use were lower than needs, and were influenced by multiple factors, primarily, service affordability and efficiency, perceived performance and hospital service quality.
The effect of women’s representation on the Global Gender Gap Index
Authors: Mastracci Sharon 
Published: March 2017

Purpose
The purpose of this paper is to find the most important factors to the Index that explains gender gaps in education, health, politics, and economic outcomes worldwide.

Design/methodology/approach
World Economic Forum (WEF) data are analyzed using hedonic regression analysis to estimate which factors affect a country’s Global Gender Gap Index. Standardized β coefficients reveal the top five factors influencing the Index, just as key components of the US Consumer Price Index are teased out using this method.

Findings
Women in public sector management, administration, and politics explain a substantial portion of gender inequality. Policies to increase women’s representation in parliaments, as heads of state, in ministerial positions, and in public sector management mitigate inequality as gauged by the Gender Gap Index. Economic indicators are also among the leading components of the Gender Gap Index.

Research limitations/implications
Although comprehensive and drawn from several sources including the World Health Organization, the International Labour Organization, and the United Nations Development Programme, WEF data do not capture the full experience of women worldwide. Subsequent qualitative research is recommended.

Practical implications
This analysis reveals policy recommendations for advocates working to close gender gaps, particularly in politics and economic outcomes. Increasing proportions of women in public sector management can mitigate inequality. This supports electoral quotas and human resource management initiatives to diversify management ranks.

Social implications
Increasing women’s share of public sector managerial positions fosters gender equity, as does increasing women’s share of elected and appointed positions.

Originality/value
This study provides quantitative evidence of the important role of women’s representation to guide subsequent fieldwork. This evidence supports efforts to increase women in elective office and public sector management.
An evaluation of corporate social responsibility communication on the websites of telecommunication companies operating in Ghana
Authors: Boateng Henry , Abdul-Hamid Ibn Kailan 
Published: March 2017

Purpose
Corporate social responsibility (CSR) communication on corporate websites have become an emerging trend by firms. Similarly, corporate websites have been used to manage stakeholders’ impressions about the organization. Meanwhile, CSR by firms have been criticized for been a manipulative tactics used by firms. The purpose of this paper therefore is to ascertain how telecommunication companies operating in Ghana communicate CSR on their corporate websites.

Design/methodology/approach
This study used a qualitative content analysis technique. It also used Bolino et al.’s (2008) impression management framework as the conceptual framework. Data were extracted from the websites of four telecommunication companies operating in Ghana. Data were analyzed using thematic analysis techniques.

Findings
The results show that the companies use impression management in communicating CSR on their corporate websites. Account, assertive impression management; blaring, boasting, defensive impression management; demonstrative impression management; exemplification, favor-rendering, illustrative impression management; ingratiation, other-enhancement, other-focused impression management; self-enhancement, self-focused impression management; and self-promotion tactics are tactics prevalent in the CSR communication of the companies. Actor-to-actor link impression management and other emotional appeal also emerged as some of the impression management tactics used by the companies.

Originality/value
This provides insights into how organizations use impression management in their CSR communication on their corporate websites. Studies of this nature are limited. Again, studies specifically adapting Bolino et al.’s impression management to study CSR communication on corporate websites are rare.
Effects of customer-based corporate reputation on perceived risk and relational outcomes: empirical evidence from gender moderation in fashion retailing
Authors: Walsh Gianfranco , Schaarschmidt Mario , Ivens Stefan 
Published: March 2017

PurposeGiven the strategic importance of firm reputation because of its potential for value creation, extant reputation research focuses on favorable customer outcomes. This study proposes and tests a model that relates the customer-based corporate reputation (CBR) of fashion retailers to customer-perceived risk and two relational outcomes – trust and commitment. In addition, this study aims to test whether or not the hypothesized paths are equally strong for male and female shoppers.Design/methodology/approachData for this study were collected through an online survey approach. Using a sample of more than 300 retail customers and structural equation modeling, the authors tested the hypotheses.FindingsDrawing on previous research, the commitment–trust theory of relationship marketing and signaling theory, the authors find support for direct and indirect links between retailers’ reputation and relational outcomes, the intervening role of perceived risk and the partially moderational role of gender.Practical implicationsThe findings of this research suggest that a retailer’s positive reputation can reduce customers’ risk and engender trust, which in turn promotes customer commitment.Originality/valueA growing number of examples suggests that retailers (specially fashion retailers) need to manage their reputation, which can come under threat in myriad ways, and its outcomes. However, so far, no individual study empirically investigated any of these reputation outcomes simultaneously or considered gender differences. Thus, the authors address an important research gap by examining the mechanism through which CBR affects relevant customer outcomes and by considering contextual factors.
