Abstract

Purpose

The purpose of this paper is to review and provide recommendations to extend the current open standard data models for describing monitoring systems and circular economy precepts for built assets. Open standard data models enable robust and efficient data exchange which underpins the successful implementation of a circular economy. One of the largest opportunities to reduce the total life cycle cost of a built asset is to use the building information modelling (BIM) approach during the operational phase because it represents the largest share of the entire cost. BIM models that represent the actual conditions and performance of the constructed assets can boost the benefits of the installed monitoring systems and reduce maintenance and operational costs.

Design/methodology/approach

This paper presents a horizontal investigation of current BIM data models and their use for describing circular economy principles and performance monitoring of built assets. Based on the investigation, an extension to the industry foundation classes (IFC) specification, recommendations and guidelines are presented which enable to describe circular economy principles and asset monitoring using IFC.

Findings

Current open BIM data models are not sufficiently mature yet. This limits the interoperability of the BIM approach and the implementation of circular economy principles. An overarching approach to extend the current standards is necessary, which considers aspects related to not only modelling the monitoring system but also data management and analysis.

Originality/value

To the authors’ best knowledge, this is the first study that identifies requirements for data model standards in the context current linear economic model of making, using and disposing is growing unsustainably far beyond the finite limits of planet of a circular economy. The results of this study set the basis for the extension of current standards required to apply the circular economy precepts.

Abstract

Purpose

The purpose of this paper is to highlight the use of the big data technologies for health and safety risks analytics in the power infrastructure domain with large data sets of health and safety risks, which are usually sparse and noisy.

Design/methodology/approach

The study focuses on using the big data frameworks for designing a robust architecture for handling and analysing (exploratory and predictive analytics) accidents in power infrastructure. The designed architecture is based on a well coherent health risk analytics lifecycle. A prototype of the architecture interfaced various technology artefacts was implemented in the Java language to predict the likelihoods of health hazards occurrence. A preliminary evaluation of the proposed architecture was carried out with a subset of an objective data, obtained from a leading UK power infrastructure company offering a broad range of power infrastructure services.

Findings

The proposed architecture was able to identify relevant variables and improve preliminary prediction accuracies and explanatory capacities. It has also enabled conclusions to be drawn regarding the causes of health risks. The results represent a significant improvement in terms of managing information on construction accidents, particularly in power infrastructure domain.

Originality/value

This study carries out a comprehensive literature review to advance the health and safety risk management in construction. It also highlights the inability of the conventional technologies in handling unstructured and incomplete data set for real-time analytics processing. The study proposes a technique in big data technology for finding complex patterns and establishing the statistical cohesion of hidden patterns for optimal future decision making.

Abstract

Purpose

In a circular economy, the goal is to keep materials values in the economy for as long as possible. For the construction industry to support the goal of the circular economy, there is the need for materials reuse. However, there is little or no information about the amount and quality of reusable materials obtainable when buildings are deconstructed. The purpose of this paper, therefore, is to develop a reusability analytics tool for assessing end-of-life status of building materials.

Design/methodology/approach

A review of the extant literature was carried out to identify the best approach to modelling end-of-life reusability assessment tool. The reliability analysis principle and materials properties were used to develop the predictive mathematical model for assessing building materials performance. The model was tested using the case study of a building design and materials take-off quantities as specified in the bill of quantity of the building design.

Findings

The results of analytics show that the quality of the building materials varies with the building component. For example, from the case study, at the 80th year of the building, the qualities of the obtainable concrete from the building are 0.9865, 0.9835, 0.9728 and 0.9799, respectively, from the foundation, first floor, frame and stair components of the building.

Originality/value

As a contribution to the concept of circular economy in the built environment, the tool provides a foundation for estimating the quality of obtainable building materials at the end-of-life based on the life expectancy of the building materials.

Abstract

Purpose

The study aims to analyze for the Spanish context the influence of the involvement of several generations in the firm's management on family firm internationalization. The authors also respond to the call in the literature to consider the influence of SEW on family firm internationalizations by analyzing the moderating effect of the importance family managers attach to each of the socioemotional wealth (SEW) dimensions – enrichment, continuity and prominence on the relationship between multiple generations involved in management and family firm internationalization.

Design/methodology/approach

The information was obtained by means of a questionnaire sent to the CEOs of family businesses. The authors’ sample consists of 147 Spanish family firms.

Findings

The authors find that the involvement of multiple generations in management is positively related to the internationalization of family firms. Furthermore, the importance that family CEOs attribute to the enrichment dimension of SEW reduces the intensity of the effect of the involvement of several generations in management on family firm internationalization.

Originality/value

The authors’ results, for the Spanish context, complement previous studies (Meneses et al., 2014) showing that the entry of new generations into the family business opens a window of opportunity for the internationalization of the family business. Furthermore, their study shows that the diverse family objectives by CEOs can have different, even conflicting effects on the internationalization decision. These results suggest that the enrichment dimension, which focuses on the short-term family goals may restrain the internationalization of the family business. However, continuity and prominence dimensions, which are related with long term family objectives and jointly enable the fulfillment of nonfamily stakeholders’ objectives, do not influence the internationalization of the family firms analyzed.

Abstract

Purpose

Google Scholar Citations (GSC) provides an institutional affiliation link which groups together authors who belong to the same institution. The purpose of this paper is to ascertain whether this feature is able to identify and normalize all the institutions entered by the authors, and whether it is able to assign all researchers to their own institution correctly.

Design/methodology/approach

Systematic queries to GSC’s internal search box were performed under two different forms (institution name and institutional e-mail web domain) in September 2015. The whole Spanish academic system (82 institutions) was used as a test. Additionally, specific searches to companies (Google) and world-class universities were performed to identify and classify potential errors in the functioning of the feature.

Findings

Although the affiliation tool works well for most institutions, it is unable to detect all existing institutions in the database, and it is not always able to create a unique standardized entry for each institution. Additionally, it also fails to group all the authors who belong to the same institution. A wide variety of errors have been identified and classified.

Research limitations/implications

Even though the analyzed sample is good enough to empirically answer the research questions initially proposed, a more comprehensive study should be performed to calibrate the real volume of the errors.

Practical implications

The discovered affiliation link errors prevent institutions from being able to access the profiles of all their respective authors using the institutions lists offered by GSC. Additionally, it introduces a shortcoming in the navigation features of Google Scholar which may impair web user experience.

Social implications

Some institutions (mainly universities) are under-represented in the affiliation feature provided by GSC. This fact might jeopardize the visibility of institutions as well as the use of this feature in bibliometric or webometric analyses.

Originality/value

This work proves inconsistencies in the affiliation feature provided by GSC. A whole national university system is systematically analyzed and several queries have been used to reveal errors in its functioning. The completeness of the errors identified and the empirical data examined are the most exhaustive to date regarding this topic. Finally, some recommendations about how to correctly fill in the affiliation data (both for authors and institutions) and how to improve this feature are provided as well.

Abstract

Purpose

The purpose of this research is to attempt to gain a deeper understanding on small to medium‐sized enterprises (SMEs) and point out some of the most serious barriers for small Spanish companies to implement such kind of strategic approach and connect it with its day‐to‐day operations.

Design/methodology/approach

After laying out the conceptual framework, and after giving a short description of the Spanish institutional landscape on corporate social responsibility (CSR), the paper focuses on SMEs and the practical issues relating to strategy design, core business and implementation as identified by managers and academics.

Findings

The paper shows a joint venture and a strategic partnership between the Javier Benjumea Chair and a new small Spanish company, in which the partners start a process of mutual help and learning. That partnership is itself an interesting experiment as a case of collaboration between the enterprise and an academic institution.

Research limitations/implications

This is only the first step in generating a model applied to improve CSR uptake at the SME level.

Originality/value

The theoretical goal that is sought after in this paper is how to advance the design of a conceptual model and tools for analyzing and managing dynamically some of the most relevant intangible aspects of an SME, in order to improve its strategic management of the relationships with the stakeholders.

Abstract

Purpose

The purpose of this paper is to evaluate the discussion of the so-called “second digital dividend”, aimed to respond to the increasing demand for mobile broadband and the need to harmonize spectrum use across the world. This paper evaluates the uncertainties of this decision and the risk of assigning too much spectrum and too early to MBB at a high cost leading to an inefficient outcome.

Design/methodology/approach

This paper analyses the trade-offs involved in the reallocation of the 700-MHz band and proposes several measures to guarantee that any further reallocation of the spectrum leads to an increase in global efficiency.

Findings

The decision to reallocate the 700 MHz band should not be adopted until policy-makers are able to guarantee that it will lead to an efficient outcome. The reallocation of the 700-MHz band requires some preliminary steps to guarantee such efficient outcome. Those preliminary policy steps should be directed to analyze the efficiency of the current use of the spectrum and enlarge the scope of policy options by freeing the currently underutilized parts of the spectrum, exploring new technologies and allowing a better spectrum management through market solutions.

Originality/value

This paper sets a framework for the evaluation of the so-called second digital dividend which differs from the evaluation of the first digital dividend. Additional cost and benefits are discussed which were not present in the first digital dividend, and that will affect the final allocation of the spectrum.

Abstract

Purpose

The purpose of this paper is to examine the potential influence of friendship on entrepreneurial teams (ETs) and on venture formation and development. The theoretical framework is built on the literature around friendship ties, the interaction of friendship ties and professional ties, and ETs.

Design/methodology/approach

Taking an interpretative methodological approach, the authors carried out qualitative interviews with ten business founders in Paris, France.

Findings

The authors identified different four profiles or types of ETs according to how friendship ties interact with professional ties among team members, which the authors designate as “fusion” and “separation”, and describe the orientation of this interaction, which the authors label as “affective” or “strategic”. These profiles affect the emergence of the idea and the choice of members in the formation of teams. They also shape the functioning of teams in terms of decision-making processes, recruitment and investment.

Research limitations/implications

The findings underline the difficulties of studying friendship in ETs empirically and recommend longitudinal approaches for further research.

Practical implications

Findings offer insights in to why and how ETs based on friendship ties approach the pre-launch, launch and development phases of businesses as well as in to the interactions between professional and friendship ties, which is helpful to both practitioners and academics. The authors also discuss the consequences and implications of the different team types in terms of their risks and strategies for mitigating these risks.

Originality/value

This is one of the first empirical studies to examine how friendship and professional ties may combine and evolve in ETs, and their influence on the entrepreneurial process as it relates to venture formation and development.
