Abstract

Purpose

At present numerical simulation of seismicity, used in mining and hydraulic fracturing practice, is quite time expensive what hampers its combined employing with observed seismicity in real time. The purpose of this paper is to suggest a mean for drastic speeding up numerical modeling seismic and aseismic events.

Design/methodology/approach

The authors propose the means to radically decrease the time expense for the bottleneck stage of simulation: calculations of stresses, induced by a large group of already activated flaws (sources of events), at locations of flaws of another large group, which may be activated by the stresses. This is achieved by building a hierarchical tree and properly accounting for the sizes of activated flaws, excluding check of their influence on flaws, which are beyond strictly defined near-regions of strong interaction.

Findings

Comparative simulations of seismicity by conventional and improved methods demonstrate high efficiency of the means developed. When applied to practical mining and hydrofracturing problems, it requires some two orders less time to obtain practically the same output results as those of conventional methods.

Originality/value

The proposed improvement provides a means for simulation of seismicity in real time of mining steps and hydrofracture propagation. It can be also used in other applications involving seismic and aseismic events and acoustic emission.

Abstract

Purpose

To date, the literature has usually assumed that a universal approach to resilience is appropriate in which different resilience capabilities are equally important for all organizations independent of contextual characteristics. In contrast this study investigates if production process characteristics affect resilience capabilities in terms of redundancy, flexibility, agility and collaboration.

Design/methodology/approach

An in-depth exploratory multiple case study was carried out in eight companies across different industries. Data were gathered through multiple interviews with key informants in each company.

Findings

The authors find differences in, and trade-offs between, resilience capabilities and practices related to redundancy, agility and collaboration induced by the different configurations of production system characteristics: especially between discrete and process industries. Further, a major influential characteristic is the production strategy employed (make-to-stock or make-to-order) which stresses or limits collaboration and redundancy.

Originality/value

This is one of the first studies to explore the effects of production system characteristics as a major contingency factor on the resilience capabilities of an organization. As such it provides valuable insights into the development of a more nuanced contingency approach to how organizations can build resilience and employ specific practices that fit their situation.

Abstract

Purpose

The authors’ contention in this paper is that the expression of subsidiary strategy in IB literature has become fragmented and incomplete. Therefore, this study aims to propose a rethink on how IB scholarship approaches the important issue of subsidiary strategy by holistically examining the discrete and integrated set of activities, choices and decisions that constitute the subsidiary strategy process for, in this context, assuming a competence-creating role within the multinational enterprise (MNE).

Design/methodology/approach

A conceptual model is designed to illustrate the holistic process of subsidiary strategy from assigned to assumed role and how a subsidiary can navigate a pathway to elevated performance and survival.

Findings

The paper identifies the key integrated elements that constitute a holistic strategic process that can enhance a subsidiary’s standing within the MNE and maximise its survival prospects.

Research limitations/implications

Particular focus is placed on subsidiaries that strategise to advance their internal corporate role to competence creator via upgraded knowledge capabilities.

Originality/value

This paper offers a roadmap for IB scholars to contribute to a future discourse around the subsidiary strategy process for assuming a competence-creating role.

Abstract

Purpose

Bulk material-handling equipment development can be accelerated and is less expensive when testing of virtual prototypes can be adopted. However, often the complexity of the interaction between particulate material and handling equipment cannot be handled by a single computational solver. This paper aims to establish a framework for the development, verification and application of a co-simulation of discrete element method (DEM) and multibody dynamics (MBD).

Design/methodology/approach

The two methods have been coupled in two directions, which consists of coupling the load data on the geometry from DEM to MBD and the position data from MBD to DEM. The coupling has been validated thoroughly in several scenarios, and the stability and robustness have been investigated.

Findings

All tests clearly demonstrated that the co-simulation is successful in predicting particle–equipment interaction. Examples are provided describing the effects of a coupling that is too tight, as well as a coupling that is too loose. A guideline has been developed for achieving stable and efficient co-simulations.

Originality/value

This framework shows how to achieve realistic co-simulations of particulate material and equipment interaction of a dynamic nature.

Abstract

Purpose

This paper aims to inform the promotion of sustainable modes of transport. For this purpose, it deploys a means-ends framework as a type of second-order cybernetics and uses it to explore cognitive transport mode choice structures.

Design/methodology/approach

The empirical study relies on a purposive sample and a qualitative research methodology known as laddering. It is aimed at the identification and comparative analysis of the cognitive means-ends structures of transport users.

Findings

The results reveal more positive and complex associations for the car than for public transport. Two main positive means-ends structures are identified for public transport, one related with the relaxation and the other with doing useful things while travelling. Dominant positive structures for the car are related with self-confidence, satisfaction and personal freedom. Negative means-ends structures in addition reveal important justifications and rationalizations for car use.

Practical implications

Based on the identified distinct means-ends elements and structures, this study holds important implications for developing a communications strategy and policy interventions seeking to promote public transport.

Originality/value

Means-ends theory is proposed as an integrative cybernetic framework for the study of stakeholders’ (customers’) mental models. The empirical study is the first to concurrently and comparatively examine positive and negative means-ends chains for the car and for the public transport modes.

Abstract

Purpose

The purpose of this paper is to explore the practice of integrated reporting (IR) assurance from the auditors’ point of view, including the main challenges to be addressed and insights on evolution and potential new assurance approaches.

Design/methodology/approach

Based on an exploratory research design, the paper conducted semi-structured interviews with 10 expert auditors, accounting assurance providers and non-accounting assurance providers, in the Italian context, combining an open coding approach with an axial coding approach, and using a three-stage process to organize data.

Findings

Respondents confirmed that current IR practices do not represent a real paradigm shift and that the need for in-depth changes in the assurance approach will depend on how these practices evolve. The main challenges highlighted are the absence of suitable criteria, the difficulty of assuring narratives and future-oriented information, and the low level of maturity of internal systems and processes of companies and stakeholders. Proposals for overcoming these challenges are framed mainly within current assurance models, although some respondents pointed out the need for a shift towards new assurance approaches.

Research limitations/implications

The paper relies on a small sample of well-informed subjects active in Italy; thus, the results may not represent the views of all auditors.

Practical implications

The findings identify areas that practitioners and assurance provider firms should focus on, looking to IR assurance and its growing importance and application as a future business area. They may be useful to standard setters and regulators to better understand limits and opportunities of requiring IR assurance on specific information not strictly related to financial information, and for the development of guidance or standards for IR assurance.

Originality/value

This research contributes to the currently underexplored area of IR assurance. Relatively few studies have investigated this topic from an empirical point of view, and no study involving auditors has been carried out in the Italian context.

Abstract

Purpose

In the most recent years, social, innovative, economic and political changes in the European context have characterized consumers' behaviours. The paper aims to understand if the use of electronic commerce differs in a situation characterized by uncertainty.

Design/methodology/approach

An innovative approach to categorising online consumer behaviour considers the self-determination theory and basic psychological needs in an uncertain scenario. The research is based on a quantitative analysis obtained by clustering algorithms on a sample of 1,000 digital users in European countries. A structured questionnaire was administered online and distributed through the leading online social platforms and direct mailing.

Findings

The results show online activities during changes in consumer behaviour patterns and retailers' strategies. This research will allow online retail managers and practitioners to obtain important information to help them define appropriate customer-oriented strategic actions to enhance value in the electronic context for both customers and firms.

Originality/value

The innovation of this research approaches the categorization of online consumer behaviour by exploiting the self-determination theory in an uncertain scenario. Precisely, the novelty of this research is to highlight three detailed categories of electronic commerce consumers, namely, unwilling, halfback and digital, to collect, store and disseminate information about these categories of Online Consumers Behaviours.

Abstract

Purpose

This study investigates how older women linguists' careers developed and led to self-employment, and this not necessarily in a linear career stage fashion. The focus is on understanding the factors that influence older women to become or continue into an entrepreneurship lifestyle, beyond economic reasons.

Design/methodology/approach

The research questions that guided this research are: (1) How have women linguists' careers developed at older or older old age? and (2) Which factors influenced women linguists' decision to become or continue as self-employed at older or older old age? This study is based on semi-structure interviews and short narratives written by ten informants about their late-career motivations and decisions. To get a holistic view of career development of women linguistics at an older age, the approach adopted in this study is explorative and interpretive, where the theoretical perspective supporting this approach derives mainly from career and wellbeing theories.

Findings

The authors’ findings signal that these self-employed older women's careers develop along parallel, explorative or expertise directions. The factors which appear to influence these women's decision to continue their careers as entrepreneurs include economic reasons (having), clearly. They also importantly point to other themes surrounding wellbeing including social relations (loving), self-realization and lifelong learning (being), entrepreneurship as a life style (acting) and meaningful extension of one's career (belonging).

Originality/value

This paper discusses how older women entrepreneurs may experience wellbeing and careers integrated together. It challenges the common notion of “career” as a one-time, linear “choice”, and instead shows how older women's entrepreneurship is a complex phenomenon.

Abstract

Purpose

Building upon the practice-based framework, this paper aims to focus on working practices for understanding how knowledge is transferred among health-care professionals within hospitals.

Design/methodology/approach

Using an ethnographic and interpretative approach, the authors conducted preliminary research based on a quali-quantitative methodology within one of the largest hospitals in Southern Italy.

Findings

This study allowed to achieve several results that could be significant and relevant within the health-care sector. First, this paper identified some of the main working practices and their associated activities in health care. Moreover, this paper identified the main organizational forms and/or tools enabling hospital personnel to share and learn the various types of knowledge for each of the prior identified practices.

Practical implications

Hospital managers should develop strategies and policies that take into account the nature and typology of knowledge-sharing processes among health-care professionals in terms of practices.

Originality/value

The paper contributes to practice-based studies identifying identified some of the main working practices, as well as the main tools for sharing and learning of the various types of knowledge.

Abstract

Purpose

A series of “learning lab” projects on disaster risk management for sustainable development (DRM-SD) have been accomplished from 2014 to 2016 in Malaysia, Vietnam, Lao PDR and Cambodia by the Centre for Global Sustainability Studies. The project is designed for professionals from the disaster risk management field to encourage integration of sustainable development (SD) concerns into the larger planning framework for DRM. As a case study for capacity building (CB) evaluation, the central purpose of this study is to explore the approaches, feedbacks and implications of the DRM-SD CB project that have been developed and carried out.

Design/methodology/approach

Three methods have been used which are participation observations, surveys and document analysis. The results show that the project had successfully applied seven different tools to enhance analytical skills and professional knowledge of development practitioners in specific areas of DRM-SD.

Findings

Based on the survey, the project received positive response and valuable information from participants for future project development. Regarding the perspective of outcomes, the result indicates that south–south, ASEAN regional and triangular cooperation and role of higher education in DRM-SD are significant impacts from this project which can bring several benefits and should be promoted as an approach for the DRM-CB project as a whole.

Originality/value

It is hoped that this study will serve as a transfer learning initiative to provide approach guidelines and innovative mechanisms for DRM practitioners who will have the know-how and potential for leadership in DRM-SD.
