A qualitative framework for selection of optimization algorithm for multi-objective trade-off problem in construction projects
Authors: Panwar Abhilasha , Tripathi Kamalendra Kumar , Jha Kumar Neeraj 
Published: May 2019

Purpose
The purpose of this paper is to develop a qualitative framework for the selection of the most appropriate optimization algorithm for the multi-objective trade-off problem (MOTP) in construction projects based on the predefined performance parameters.

Design/methodology/approach
A total of 6 optimization algorithms and 13 performance parameters were identified through literature review. The experts were asked to indicate their preferences between each pair of optimization algorithms and performance parameters. A multi-criteria decision-making tool, namely, consistent fuzzy preference relation was applied to analyze the responses of the experts. The results from the analysis were applied to evaluate their relative weights which were used to provide a ranking to the algorithms.

Findings
This study provided a qualitative framework which can be used to identify the most appropriate optimization algorithm for the MOTP beforehand. The outcome suggested that non-dominated sorting genetic algorithm (NSGA) was the most appropriate algorithm whereas linear programming was found to be the least appropriate for MOTPs.

Originality/value
The devised framework may provide a useful insight for the construction practitioners to choose an effective optimization algorithm tool for preparing an efficient project schedule aiming toward the desired optimal improvement in achieving the various objectives. Identification of the absolute best optimization algorithm is very difficult to attain due to various problems such as the inherent complexities and intricacies of the algorithm and different class of problems. However, the devised framework offers a primary insight into the selection of the most appropriate alternative among the available algorithms.
The diversity of knowledge sources and its impact on firm-level innovation
Authors: Abdul Basit Shoaib , Medase Kehinde 
Published: May 2019

PurposeThe combination of different knowledge sources has been considered conducive for innovation performance. While the literature has advanced regarding the combination of knowledge inputs as in internal and external research and development (R&D), the evolvement of knowledge blend from customers and competitors has also received substantial attention. The purpose of this paper is to delineate the sources of information from the customers into private and public and examine their direct effect on firm-level innovation. While the extant literature is mixed regarding this, no clear-cut results have emerged yet on the effect of knowledge combination from the private and public customers with internal R&D and human capital on innovation activities. This study, however, shed more lights on the inconclusiveness of the effect of knowledge diversity on firm-level innovation.Design/methodology/approachUsing the microdata from the German Community Innovation Survey 2013, the authors employ a binary instrumental variable treatment model with Heckman selection, a suitable strategy to estimate binary variables to cope with a possible endogeneity issue.FindingsThe paper demonstrates that knowledge from customers in the private and public sector, and competitors are positively and significantly associated with innovation. The authors find evidence of a positive and significant effect of the combination of firm internal knowledge competencies with information from the public sector. In contrary, the blend of knowledge competencies with information from customers in the private sector and information from the competitors results in decline to innovation. The results also show that the blend of internal R&D with knowledge source from the customers in the public sector appears to have a stronger influence in the manufacturing sector than services. The results offer strong evidence of the positive link between knowledge diversity and firm-level innovation performance.Practical implicationsThe results have significant managerial implications on the role of the blend of different sources of information in supporting a compelling internal knowledge development to optimise innovation performance.Originality/valueThis study is foremost to focus on knowledge sources from the customers in the public and private sector and its relationship with R&D and human capital in supporting a successful introduction of innovation.
Human resource strategies for organizational ambidexterity
Authors: Kim Andrea 
Published: May 2019

PurposeThe purpose of this paper is to propose a comprehensive framework that delineates how human resource (HR) practices are differentially configured for exploitative and explorative innovation as well as how the sets of HR practices support these two types of innovation.Design/methodology/approachBased on the structural ambidexterity approach and a bottom-up process in the multilevel theories, this research derives the need for the differential managerial structures for exploitation and exploration at the unit level. In addition, the Input–Process–Outcome model of team effectiveness and multilevel theories are employed to discuss the internal nature (e.g. resources, work styles) of exploiting and exploring units. Finally, building on strategic HR management literature, this research configures exploitation-targeted and exploration-targeted HR systems and delves into how these differentiated HR systems generate differential inputs of human capital resources and thereby foster exploitative and explorative innovation processes.FindingsThis research proposes several factors for exploitation and exploration, including: necessary inputs (i.e. commitment, narrowness, and cohesion for exploitation vs thoughtfulness, breadth, and openness for exploration), idiosyncratic innovation processes (i.e. convergent collective cognition vs divergent collective cognition), and differentiated HR systems comprised of different forms of unit staffing (homogeneity vs heterogeneity), performance appraisal, incentives, and training and development (short-term vs long-term orientation).Originality/valueThe proposed theoretical framework contributes to an improved understanding of the psychological foundation of organizational ambidexterity and systematizing how diverse HR practices work together to elicit exploitative and explorative innovation from employees.
Creating “them” and “us”
Authors: Tomsic Mary , Deery Claire Marika 
Published: May 2019

Purpose
The purpose of this paper is to examine how the contemporary “refugee crisis” is being presented to children through picture books and teaching materials. It uses the concept of refugeedom as an approach that takes into account the multiple facets involved in the forced movement of people in the past and present and seeks to show the value of historical understandings in educational contexts when framing resources for teachers and students.

Design/methodology/approach
The paper examines a sample of high-profile English language picture books about children’s stories of forced displacement and the most prominent freely available teaching materials connected to the books. A critical discursive analysis of the books and educative guides considers the ways in which ideas and information about forced displacement is framed for child readers and children in primary school classrooms. The context for the authors’ interest in exploring these books and educational resources is that in response to the numbers of children who are part of the current “refugee crisis” alongside a public call for the “crisis” to be explained to children.

Findings
The paper argues that picture books open up spaces for children to explore refugeedom through experiences of forced movement and various factors involved in the contemporary “refugee crisis”. In contrast, in the teaching resources and some peritextual materials, the child in the classroom is addressed as entirely disconnected from children who are forcibly displaced, students in classrooms are positioned to learn from the refugee “other”. When links are made between students in classroom and children who have been forcibly displaced it is through activities that position students in classrooms to imagine themselves as forcibly displaced, or to suggest they act within a humanitarian framework of welcoming or helping refugees. The authors believe that if teaching resources were more directly informed by discipline specific tools of historical concepts, more nuanced approaches to past and present histories of forced movement could be considered and from that more fruitful learning opportunities created for all students.

Practical implications
This research provides ideas about how materials to support the use of picture books in educational settings could be developed to promote historical thinking and contextualisation around key social and political issues in the world today. It also makes the case for historians to be involved in the creation of teaching materials in a collaborative way so that academic insights can be brought to teachers and students at all levels of education.

Originality/value
The value of this research is to understand how children are positioned in reading and learning about forced displacement and query the impact of decontextualised approaches to learning. It argues for the critical interpretative value that historical understanding can bring to present day issues which are history in the making.
Influential factors for intention to visit an adversarial nation: increasing robustness and validity of findings
Authors: Stepchenkova Svetlana , Kirilenko Andrei P. , Shichkova Elena 
Published: May 2019

Purpose
The purpose of this paper is to investigate the drivers of visitation intention, including demographic, psychographic (animosity, national attachment and consumer ethnocentrism) and image factors on tourist decision-making in a situation of bilateral conflict between the destination country and the source country, that is, the USA and Russia, respectively.

Design/methodology/approach
The data were collected at two different points in time from two different samples but analyzed with the same research question in mind. To increase the robustness and validity of findings, three analytical approaches from the repertoire of statistics and data mining techniques such as hierarchical linear regression, logistic regression and decision tree analysis were applied to two independent samples of tourists with different demographic profiles. This multiple methods research employs a complementary design, as methods used have equal importance and are applied concurrently.

Findings
The paper obtained generally consistent results across methods and samples: general animosity, destination image and country image are the most influential factors in the tourists’ decision-making to visit a destination country with which their own country has strained bilateral relations.

Practical implications
Destination image is highly important in all analyses and is more favorable than country image. It indicates some degree of separation of the two images in the respondents’ mind, which indicates that marketing a country as a tourist destination on a not-so-friendly tourism market may still be effective. Results also tentatively indicate that for young adults, patriotic feelings matter more in their decision-making, while for more mature tourists, ethnocentric tendencies play a more important role.

Originality/value
The paper examines the influence of general and situational animosity, national attachment, and consumer ethnocentrism on visitation intentions in a situation of conflict between the two nations and, thus, expands the empirical evidence accumulated to date on tourist behavior in conflict. The paper acts on the premise that if a connection between any two variables truly exists, it should be able to withstand variations in samples, timing of data collection and measurement, thus, leading to more robust findings.
Effect of laser surface texturing on wear resistance of nickel based superalloy
Authors: F. Peter Prakash , Duraiselvam Muthukannan , S. Natarajan , Balamurugan Kannan Ganesa 
Published: May 2019

Purpose
This paper aims to investigate the effect of laser surface texturing (LST) on the wear behavior of C-263 nickel-based superalloy and to identify the optimum wear operating condition.

Design/methodology/approach
C-263 nickel-based superalloy was selected as substrate material and pico-second Nd-YAG laser was used to fabricate the waviness groove texture on their surface. Wear experiments were designed based on Box-Bhenken design with three factors of sliding velocity, sliding distance and applied load. Wear experiments were performed using pin on disc tribometer. Morphologies of textures and worn-out surfaces were evaluated by scanning electron microscopy and energy dispersive spectroscopy. Surface topographies and surface roughness of the textures were evaluated by weight light interferometry. The response surface methodology was adopted to identify the optimum wear operating condition and ANOVA to identify the significant factors.

Findings
LST improves the wear resistance of C-263 nickel-based superalloy by appeoximately 82 per cent. Higher wear rate occurs at maximum values of all operating conditions, and applied load affects the coefficient of friction. Applied load significantly affects the wear rate of un-textured specimen. The interaction of sliding velocity and applied load also affects the wear rate of textured specimens. The optimum parameters to get minimum wear rate for un-textured specimens are 1.5 m/s sliding velocity, 725 m sliding distance and 31 N of applied load. For textured specimens, the optimum values are 1.5 m/s sliding distance, 500 m sliding distance and 40 N of the applied load.

Originality/value
Literature on laser texturing on nickel-based superalloy is very scarce. Specifically, the effect of laser texturing on wear behavior of the nickel-based superalloy C-263 alloy is not yet reported.
The role of corporate controls and business-level strategy in business unit performance
Authors: Seifzadeh Pouya , Rowe W. Glenn 
Published: May 2019

PurposeCorporate controls are mechanisms that corporations use to ensure that the processes and/or outcomes of their business units meet corporate expectations. Challenges in measurement of corporate controls have led many researchers to operationalize them as part of the more ambiguous corporate effects construct, instead of addressing them separately. The purpose of this paper is to examine the significance of “fit” between corporate control mechanisms and business unit strategy in performance of business units.Design/methodology/approachThe authors use ordinary least squares regression analysis on data collected between 2010 and 2012 from surveys from managers of 142 Iranian corporations and 1,822 of their subsidiaries. The authors also use financial and market data collected by an IDRO division and accessed through partnership in a joint project.FindingsThe authors found that while the fit between business unit strategy and corporate controls has a significant effect on business unit financial performance, it does not have a similar effect on market performance. The findings demonstrate that when business unit managers perceive that they are subject to a balance of strategic and financial controls with a slightly greater emphasis on strategic controls, then business units have higher financial and market performance, although the difference in financial performance is not significant.Research limitations/implicationsThe authors find that the misfit between corporate controls and business strategies in such cases could negatively affect the performance of the business unit. However, this research also contributes to a better understanding of the importance of strategic controls to the successful performance of business units. The findings show that while the fit between controls and strategy is most critical for achieving financial performance in business units that pursue product leadership, strategic controls play a more prominent role than financial controls in achieving higher financial or market share performance for all business units.Practical implicationsThe findings of the propositions in this research would discourage corporations with tight financial control from engaging in acquisition of businesses considered to be product leaders in their relative product markets.Originality/valuePast research focusing on the fit between corporate-level factors and business-level factors and their role on business performance are largely limited to conceptual work. The limited empirical studies completed in the past generally reduce control mechanisms to lack or absence of autonomy. This shortcoming has been mainly due to difficulties in measurement of control mechanisms. The empirical study overcomes these barriers and in doing so, reveals surprising findings related to the effectiveness of different control mechanisms.
Strategic compatibility, collaboration and collective impact for community change
Authors: Brown Mary Ellen , Rizzuto Tracey , Singh Pallavi 
Published: May 2019

Purpose
Communities are best able to tackle complex social problems when solutions are achieved collaboratively. Inter-organizational partnerships are strongest and provide the greatest benefit to communities when the relationships are mutually compatible. The purpose of this paper is to introduce an evidence-informed approach to identifying and forming mutually compatible collaborations among organizations responsible for promoting community well-being and carrying out community-level interventions.

Design/methodology/approach
A three-stage case study examines the utility of a novel measurement tool for identifying opportunities for strategic collaboration. The strategic compatibility assessment (SCA) was designed to identify inter-organizational collaborative capacities within and across sectors as a means to motivate collaborative behaviors that are essential to community change initiatives that advance the collective impact.

Findings
The findings of this paper indicate the SCA is an effective tool for fostering mutually beneficial collaborative partnerships. A high degree of content, face and practical validity was evidenced in two independent studies of SCA, and organizations using the SCA tool reported a moderate-to-high degree of collaborative behavior in a post-intervention assessment of SCA outcomes. These findings provide field-based support for the SCA to promote cross-sector collaboration for community-level interventions.

Originality/value
The SCA tool describes the degree of collaboration among organizations that operate within a neighborhood; identifies potential points of mutual compatibility within the network; and creates pathways for leveraging collaborative behavior to promote community capitals. The aim of this research is to examine the potential of the SCA tool to shift the non-profit sector climate away from one characterized by competition toward one rich with collaboration.
Transformational leadership with innovative behaviour
Authors: Amankwaa Albert , Gyensare Michael Asiedu , Susomrith Pattanee 
Published: May 2019

PurposeThe purpose of this paper is to examine simultaneously multiple mediating mechanisms through which transformational leadership affects innovative work behaviour (IWB). Specifically, the authors test job autonomy, affective commitment and supportive management as the three mediating paths through which transformational leadership predicts innovative wok behaviour.Design/methodology/approachData were collected from 358 employees working in large retail banks in Accra, the capital of Ghana. A partial least squares structural equation modelling technique was used to estimate the measurement and structural models.FindingsJob autonomy and supportive management rather than affective commitment mediated the relationship between transformational leadership and IWB. In addition, transformational leadership positively relates to job autonomy, affective commitment, supportive management and IWB.Practical implicationsBy adopting leadership behaviours that seek to offer employees freedom on the job, a feeling of attachment to the organisation and positive perception of leadership support, managers and HR professionals can potentially foster employee innovation. This could stimulate organisational innovation and business success in the financial sector.Originality/valueAlthough it is important to understand the mechanisms or processes through which transformational leadership behaviour promotes IWB, research in this area is scanty and scarce. This study theorises and empirically examines job autonomy and support management as novel mechanisms through which transformational leadership behaviour translates into workers’ innovative behaviour in formal banking institutions.
Whose value? Problems in valuing social enterprise and research implications
Authors: Chandra Yanto 
Published: May 2019

Purpose
This paper argues that we need a more disciplined understanding of social enterprise (SE) that is able to incorporate its diversity across different contexts, yet remains sympathetic to its core ideal of value creation. This paper aims to revisit the meaning of value creation to reflect critically upon the diverse forms of SE.

Design/methodology/approach
This paper uses the Aristotelian causes, namely, the formal, efficient and final causes, to problematize the meaning of value creation.

Findings
This paper shows that SEs can create or destroy value depending on who evaluates the value. It also raises the issue that how value is created – the motives, means and action – is affected by the ethical orientation of the actors. Lastly, it encourages researchers to pay attention to how stakeholders are defined in SE, in light of the diverse nature of organizations that are labelled as SEs.

Research limitations/implications
This paper demonstrates that the current definition of SE is inadequate, and to-some extent, problematic. It then proposes some future research agendas, to unpack the issue of value creation, through social cost, politics, transparency and legal perspectives.

Originality/value
This research makes new contribution to the SE literature by injecting an Aristotelian perspective to problematize and reframe the meaning of value creation. It asks scholars to answer these questions: from whose perspective is value created or destroyed (formal cause), how is value created (efficient cause) and for whom is the value created (final cause)?
