Are emojis fascinating brand value more than textual language? Mediating role of brand communication to SNS and brand attachment
Authors: Arya Vikas , Sethi Deepa , Verma Hemraj 
Published: October 2018

Purpose
The purpose of this paper is to understand the relationship of consumers’ engagement on social networking sites (SNSs) and their brand attachment behavior in the presence of a mediator, brand communication. Further, this mediation has been studied with presence of emojis as one of the significant moderator.

Design/methodology/approach
Following a descriptive research design, an empirical investigation was carried out by approaching 252 respondents from India to collect data through online survey forms as well as physical questionnaires. The research instrument was developed using a five-point Likert-type scale and items for the constructs in study were taken after literature review. The SPSS 22.0, AMOS 24.0 and Process (Prof A. Hayes) and Daniel Soper’s statistical tool called “Interaction” for moderation graph were employed for data examination and hypothesis analysis.

Findings
It was found that brand communication mediated the relationship between consumer engagement on SNSs and brand attachment significantly. The availability of emojis for a company during a conversation or in digital ad campaigns on SNSs acts as a mediating moderator and its impact on consumers’ brand attachment behavior is very strong through brand communication.

Originality/value
The study is original in the sense it provides insights into understanding consumer brand attachment behavior on SNSs.
The convergence of National Professional Qualifications in educational leadership and master’s level study
Authors: Lambert Steve 
Published: October 2018

Purpose
In 2017 the UK Government decided that the suite of National Professional Qualifications (National Professional Qualifications for Middle Leadership, National Professional Qualifications for Senior Leadership and National Professional Qualifications for Headship) needs to be updated in order to ensure they remained relevant to the changing shape of the educational landscape, particularly through the expansion of multi-academy trusts (MATs). At the same time, the Government proposed a new National Professional Qualification for Executive Leadership aimed at the CEOs of MATs. The purpose of this paper is to explore the way in which the new National Professional Qualification (NPQ) programmes are having master’s level criteria embedded into them to facilitate a seamless progression into the master’s level study.

Design/methodology/approach
The paper combines desk research with reflections on the experience of developing the new NPQ programme within higher education institutions (HEIs) and considers the implications of this upon current and emerging HEI practice and research into educational leadership.

Findings
There were a number of key issues highlighted by the paper. Notably, the process of embedding academic criteria into a training programme, which was not used to support the notion of critical reflection. Also, the associated mechanisms of accreditation, existing professional networks and the upskilling of staff delivering the NPQ programme, and a professionally oriented interface between the university, employer and deliverer of the training.

Originality/value
This paper provides an original perspective involving the embedding of master’s level criteria into professional qualifications in the field of educational leadership.
Modeling MHD swirling flow due to rough rotating disk with non-linear radiation and chemically reactive solute
Authors: Mustafa M. , Mushtaq Ammar , Hayat T. , Alsaedi A. 
Published: October 2018

Purpose
This study aims to deal with the laminar flow owing to rough rotating disk in the existence of vertical magnetic field and partial slip effects. The aim is to resolve heat transfer problem in the existence of non-linear radiative flux and thermal slip effects. The study also analyzes the mass transfer process when the flow field contains chemically reacting species.

Design/methodology/approach
Modified von-Kármán transformations are applied to change the conservation equations into similar forms. The transformed equations are treated by a convenient shooting method and by contemporary built in routine bvp4c of MATLAB.

Findings
The numerical solutions are used to address the role of main ingredients of the problem, namely, wall roughness, radiation and chemical reaction on the flow fields.

Research limitations/implications
Temperature profiles are considerably affected by a parameter measuring wall to ambient temperature ratio. Furthermore, behavior of concentration field is highly influenced by the reaction rate of the diffusing species.

Originality/value
The concept of non-linear radiation in chemically reactive flow over a rotating disk is just introduced here.
Cultural identity in WHS tourist destinations: the case of Cordoba (Spain)
Authors: Lopez-Guzman Tomas , Pérez Gálvez Jesús Claudio , Muñoz-Fernández Guzmán Antonio , Medina-Viruel Miguel Jesús 
Published: October 2018

Purpose
The purpose of this paper is to conduct an analysis of the relationships existing among three basic constructs in the visitor’s decision-making process (motivation and satisfaction) in a tourist destination that is a World Heritage Site, such as the city of Cordoba (Spain). Bearing in mind the perception of heritage by the foreign visitors, the following four types were determined: alternative tourists, cultural tourists, emotional tourists and heritage tourists.

Design/methodology/approach
This paper uses the multivariate technique of grouping cases (K-means clusters) to analyse the similarity existing among the surveyed persons. From the groups or segments obtained, statistics and measurements of association were applied that provide the information necessary to study the possible trends of association existing between variables from a table of bidimensional contingencies. In the same way, non-parametric statistical procedures were used (Kruskal–Wallis H test and the Mann–Whitney U test).

Findings
The results show the existence of four diverse motivational dimensions among the foreign tourists to visit it: hedonic, cultural, convenience and circumstantial. Of the four dimensions, the hedonic and the cultural are the most relevant. The results show the existence of a common cultural identity: the Arabic cultural identity.

Originality/value
This paper contributes to complete the academic literature existing on the links of the tourist with the historical and monumental heritage that he visits, and with the tourist’s behaviour.
Adoption of light steel (LS) for building projects in South Africa
Authors: Dosumu Oluwaseun , Aigbavboa Clinton Ohis 
Published: October 2018

PurposeThis paper aims to investigate the level of awareness about, adoption of and willingness to adopt light steel (LS) for building projects. It also assessed the benefits, challenges and solutions to the challenges of adopting LS for building projects.

Design/methodology/approachThe quantitative (questionnaire) research method was used for the study. The research design was survey in nature. The whole-population cluster sampling technique was adopted. The clusters were the LS buildings from two (Western Cape and Gauteng) out of the eight provinces in South Africa. The respondents were the construction organizations that have executed LS building projects in the selected provinces. Hence, 56 firms filled and returned the questionnaire. Data analysis was done with frequency, mean scores, t-test and analysis of variance (normality of data distribution assumed).

FindingsResults indicated that, out of the 29 areas of application of LS identified in literature, respondents were aware of 11 areas, adopted LS for seven areas and were willing to adopt LS for six areas. Respondents also noted that 18 of the 25 identified benefits of LS were relevant to South Africa. Despite the benefits, few developers embrace it, it is a threat to suppliers’ and contractors’ businesses and it delays building approval due to low awareness.

Practical implicationThe implication of the results is that there is low awareness about, adoption of and willingness to adopt LS for building projects in South Africa, and this may be due to the identified challenges. To boost the awareness about, adoption of and willingness to adopt LS, LS technologies need to be imported, LS warehouses should be provided in all cities and it must be ensured that LS building projects are cheaper than conventional buildings.

Originality/valueThe value of the study is that the adoption of LS for building projects will improve the capacity of sustainable development.
Interactive effects of human capital in finance–economic growth nexus in Sub-Saharan Africa
Authors: Ibrahim Muazu 
Published: October 2018

Purpose
The purpose of this paper is to examine the interactive effect of human capital in financial development–economic growth nexus. Relative to the quantity-based measure of enrolment rates, the main aim was to determine how quality of human capital proxied by pupil–teacher ratio influences the relationship between domestic financial sector development and overall economic growth.

Design/methodology/approach
Data are obtained from the World Development Indicators of the World Bank for 29 sub-Saharan African (SSA) countries over the period 1980–2014. The analyses were conducted using the system generalised method of moments within the endogenous growth framework while controlling for country-specific and time effects. The author also follows Papke and Wooldridge procedure in examining the long-run estimates of the variables of interest.

Findings
The key finding is that, while both human capital and financial development unconditionally promotes growth in both the short and long run, results from the interactive terms suggest that, irrespective of the measure of finance, financial sector development largely spurs growth on the back of quality human capital. This finding is also confirmed by the marginal and net effects where the interactive effect of pupil–teacher ratio and indicators of finance are consistently huge relative to the enrolment. Statistically, the results are robust to model specification.

Practical implications
While it is laudable for SSA countries to increase access to education, it is equally more crucial to increase the supply of teachers at the same time improving on the limited teaching and learning materials. Indeed, there are efforts to develop rather low levels of the financial sector owing to its unconditional growth effects. Beyond the direct benefit of finance, however, higher growth effect of finance is conditioned on the quality level of human capital. The outcome of this study should therefore reignite the recognition of the complementarity role of human capital and finance in economic growth process.

Originality/value
The study makes significant contributions to existing finance–growth literature in so many ways: first, the auhor extend the literature by empirically examining how different measures of human capital shape the finance–economic growth nexus. Through this the author is able to bring a different perspective in the literature highlighting the role of countries’ human capital stock in mediating the impact of financial deepening on economic growth. Second, the author makes a more systematic attempt to evaluate the relative importance of finance and human capital in growth process while controlling for several ancillary variables.
Exports’ effects on productivity from the view of industry heterogeneity
Authors: Jiao Yifan , Liu Qing , Liu Tianzhuo 
Published: October 2018

Purpose
The relationship between exports and productivity has always been a hot topic for scholars, but no unified conclusions have been made by theory and empirical research so far. There is no denying that the relationship between the two is important though, exploring the factors affecting the relationship can bring much more reflection and inspiration.

Design/methodology/approach
After using stochastic frontier analysis which includes stochastic factors to calculate total factor productivity, this paper makes regressions on the panel data of Chinese manufacturing industries from 2004 to 2013. In addition, it also tests the roles of industry heterogeneity plays in analyzing the relationships between exports and productivity.

Findings
It turns out that in China, exports inhibit the growth of productivity overall, and scale effect is not reflected in the export sector. From the perspective of sub-sectors, exports dampen the productivity significantly in labor-intensive industries, which may be because of low learning ability. In industries with low R&D investment, exports also have significant and negative effects on industry productivity, which is because the R&D capital is not efficient and sufficient to be converted to productivity. In industries with high foreign capital rate, exports prohibit the growth of productivity because of the existence of much processing trade. In industries with low competition pressure, exports hinder the productivity because firms in such industries are possibly not competitive enough to survive in the fierce international market.

Originality/value
To the best of the authors’ knowledge, previous research studies did not take the industry heterogeneity into consideration when discussing the effects of exports on productivity. In this paper, cost types, R&D investment, energy consumption efficiency, export destination, foreign investment rate, state-owned ratio, competition pressure and international competitiveness are all discussed in the analysis of export and productivity. This study provides new insights to help understand the mechanism of export and productivity and the conclusions are of rich policy implications.
Sustainability risk management in a cooperative environment under uncertainty
Authors: Moradi Mojtaba , Hafezalkotob Ashkan , Ghezavati Vahidreza 
Published: October 2018

Purpose
This study considers a project scheduling model to assess the project risks and the impacts on project sustainability when subcontractors collaborate under uncertainty. Moreover, some allocation methods are applied for fair allocating utility of the project and supper-additivity, stability and satisfaction level of each coalition. Finally, sustainability concept is considered in risk assessment in all coalitions.

Design/methodology/approach
The proposed mathematical programming model evaluates project risks when the subcontractors cooperate with each other by sharing their limited resources. Then, some cooperative game theory methods are applied for fair allocation of net present value, of the cooperation and finally sustainability aspects (economic, social and environmental) are investigated in risk assessment for each possible coalition.

Finding
The results of the proposed model indicate that the subcontractors can increase their profit by 10 per cent ($14,028,450 thousand) and save the equilibrium between sustainability aspects especially in grand coalition. It means that subcontractors do not have incentive to leave the coalition and the supper-additive property is feasible. Furthermore, risk assessment shows that project risks have less impact on subcontractor profits when they cooperate with each other.

Originality/value
Sustainability aspects may be investigated in project management in previous studies, but the authors study sustainability indicators when subcontractors form a coalition and share their resources in response to the risks of availability to resources and delay in completing the project under uncertainty.
An exploration of motives, constraints and future participation intention in sport and exercise events
Authors: Koronios Konstantinos , Kriemadis Thanos 
Published: October 2018

PurposeThe purpose of this paper is to explore relations among constraints and motivation for running events commitment along with relations among motivation and future commitment intentions.Design/methodology/approachA quantitative approach was utilized for the aim of the present study and 1,944 questionnaires were gathered. The self-determination theory and the categorization among intrinsic and extrinsic motivators as proposed by Alexandriset al.(2002) were utilized and the suggested research tools were selected for the purposes of the study.FindingsIntrapersonal constraints found to influence motivation factors while all three motivation factors had a significant effect on continuous participation intentions.Research limitations/implicationsThe experimental data for the present research came from participants in a given running race. As mentioned in the discussion, the distinctive characteristics of running may have affected the examined relations in a way which might not be straightforwardly pertinent to different sports. Additional analysis in various activities is essential for the generalization of the findings.Originality/valueThis paper provides the context for a discussion. It shows that motivation factors (amotivation, intrinsic and extrinsic motivation) have a significant influence on individuals’ intention to participate in sport and exercise, as well as on their ability to negotiate associated constraints. The large sample is a major element of the originality of this study because adds to the validity of the results.
Selective integration of management systems: a case study in the construction industry
Authors: Chountalas Panos T. , Tepaskoualos Filippos A. 
Published: October 2018

PurposeDespite the widely recognized benefits of integrating management systems, many multi-certified organizations continue to implement two or more systems separately. This can happen either through ignorance or by deliberate intent. Focusing on the second reason, the purpose of this paper is to examine a number of factors that can lead an organization to consciously choose not to integrate all of its management systems.Design/methodology/approachThe paper presents a case study of a construction company that has integrated the environmental management system and the occupational health and safety management system – which implies that the company is familiar with the practice of integration – while choosing to implement the quality management system separately from the other two.FindingsThe findings of this study show that the reasons that led the company not to integrate all of its systems are not so much related to the compatibility of these systems, but are much deeper and have implications that touch upon its basic principles and values. Despite the occurrence of some organizational and operational problems (such as complexity of administrative issues and bureaucracy), the separate implementation of the systems allowed the company to preserve both the balance between the powers of its executives and the ability to attach special importance to each area: quality, environment, health and safety.Originality/valueThis study will be useful in order to understand that selective integration of management systems is based on the belief that integration is not ade factodesirable goal, especially when the estimated cost-benefit ratio of non-integration is better than that of integration.
Integrated geophysical exploration in onshore frontier basins
Authors: Martini F. , Rogers E. , Bennett S. , Davi R. , Doherty J.T. , Mongan J. 
Published: October 2018

ABSTRACTFaced with the challenge of rapidly screening a huge expanse of frontier exploration acreage, often characterized by sparse vintage data, it is our experience that a combination of appropriate air‐ and ground‐based geophysical techniques contributes positively to the exploration value chain. Airborne gravity gradiometry in conjunction with conventional gravity and magnetic data, as well as geological knowledge, add significant value to the screening process. This combination can subsequently assist in optimizing the location of the more time‐consuming and expensive seismic programme. In addition, analysis and inversion of passive seismic data have also proven useful in providing depth to basement estimates, and results derived from all the techniques investigated have been consistent within several study areas. Following initial tests, where the data were independently analysed and cross‐checked for consistency (including comparisons with active source seismic data and well data, when available), the company now routinely adopts the integration of these techniques in our frontier exploration acreage to support sedimentary basin delineation and mapping. This allows the optimal positioning and focussing of the higher spend and higher footprint programmes, such as active reflection seismic.
Inbreeding shapes tuberculosis progression in female adult badgers (Meles meles)

AbstractIn Focus: Beton, C. H., Delahay, R. J., Smith, F. A. P., Robertson, A., McDonald, R. A., Young, A. J., Burke T. A., & Hodgson, D. (2018). Inbreeding intensifies sex‐ and age‐dependent disease in a wild mammal. Journal of Animal Ecology, 87, 1497‐1499. https://doi.org/10.1111/1365-2656.12878Increasing crossbreeding of relatives promotes inbreeding which, in turn, can cause a reduction in fitness and the emergence of a phenomenon known as inbreeding depression. Benton et al., used the badger (Meles meles)—Mycobacterium bovis model system to study the relationship between inbreeding, disease, ageing and sex. A link between multilocus homozygosity (general effect) and TB progression (measured as antibody response to infection) and between homozygosity at specific loci (local effect) and TB progression were established in this study, highlighting the importance of host genetic background in determining host disease outcomes, and thus on shaping disease dynamics in wild populations. Moreover, the authors demonstrated for the first time in a natural population that this positive association might be modulated by sex and age. In infected individuals, inbreeding only affects disease progression in adult females.

Published: October 2018

BackgroundThis study was conducted to evaluate the prognostic and recurrent impact of EGFR mutation status in resected pN0M0 lung adenocarcinoma with consideration of the histological subtype.MethodsFollowing retrospective analysis of whole 474 consecutive pathological N0M0 lung adenocarcinoma patients, the prognostic significance of EGFR mutation status was evaluated in limited 394 subjects. Overall survival and recurrence‐free interval (RFI) were estimated using the Kaplan–Meier method and compared using a log‐rank test. Univariate and multivariate analyses were performed using Cox proportional hazard models.ResultsThe five‐year RFI was 85.7% and 93.3% for EGFR positive (n = 176) and negative (n = 218) cases, respectively (hazard ratio [HR] 1.992, 95% confidence interval [CI] 1.005–3.982; P = 0.048). Following the exclusion of specific subtypes free from recurrence or EGFR mutation (adenocarcinoma in situ, minimally invasive adenocarcinoma, and invasive mucinous adenocarcinoma), the five‐year RFI was obviously poorer in EGFR positive compared to negative cases (80.7% and 92.1%, respectively; HR 2.163, 95% CI 1.055–4.341; P = 0.035). Multivariate analysis excluding the specific subtypes confirmed that male sex, age, current or Ex‐smoking status, pleural invasion, and EGFR‐positive status were independently associated with shorter RFI. No significant differences in five‐year overall survival were found between the EGFR mutation positive and negative groups (88.7% and 93.7%, respectively; HR 1.630, 95% CI 0.787–3.432; P = 0.2).Conclusion
EGFR mutations are associated with recurrence in pN0M0 lung adenocarcinoma. EGFR mutation status and histological subtype should be considered when evaluating the risk of recurrence in resected lung adenocarcinoma patients.
