The purpose of this paper is to describe further developments on a novel formulation of the boundary element method (BEM) for inelastic problems using the dual reciprocity method (DRM) but using object-oriented programming (OOP). As the BEM formulation generates a domain integral due to the inelastic stresses, the DRM is employed in a modified form using polyharmonic spline approximating functions with polynomial augmentation. These approximating functions produced accurate results in BEM applications for a range of problems tested, and have been shown to converge linearly as the order of the function increases.

A programming class named DRMOOP, written in C++ language and based on OOP, was developed in this research. With such programming, general matrix equations can be easily established and applied to different inelastic problems. A vector that accounts for the influence of the inelastic strains on the displacements and boundary forces is obtained.

The C++ DRMOOP class has been implemented and tested with the BEM formulation applied to classical elastoplastic problem and the results are reported at the end of the paper.

This teaching case seeks to explain the main aspects of Acciona's sustainability strategy and the process of transformation of the company after the new CEO took office in 2004. It also aims to present some possible difficulties of maintaining such strategies in the new economic and political environment. The purpose of the case is to show how three aspects play a relevant role in a company's transformation towards sustainability: cultural change; collaboration with external stakeholders; and the innovations introduced.

The paper presents a case study that narrates the process of six years of transformation towards sustainability of a company. The case was constructed through the analysis of company documents and several interviews with key actors in the company as well as external stakeholders.

The paper shows how cultural change, collaboration with external stakeholders and innovation form a vital combination in the transformation process towards sustainability. It also reveals that acquisitions and internationalization can help accelerate or consolidate this process.

The paper is presented as a teaching case with discussion questions at the end. The aim is to engage readers and participants in educational and training programmes in discussions about the factors that may contribute to start and maintain a transformation towards sustainability. The practical implication of the paper is to show how cultural factors, collaboration and innovation form a vital combination for changing the way businesses do things.

The value of the case lies in showing how business efforts of embedding sustainability into business practice can be more effective by combining cultural factors, collaboration and innovation.

Terrorism, an important component of Political risk as a possible determinant of ADRs (American Depository Receipts) returns have received little attention in academic literature. To address this issue and examine whether political risk is a major determinant of ADR returns of emerging market countries, this paper empirically examines market valuation of Indian ADRs around acts of terrorism. Using a sample of 52 such events in the sample period Jan 2003‐Dec 2003 we empirically analyze returns of Indian ADRs. The results from our study indicate a marginally negative significant effect, failing to indicate that event of terrorist attacks severely affect the Indian ADRs listed on the US stock market. This may be explained by a combined effect of; (a) the optimism of US investors towards emerging markets, and (b) market participants becoming more resilient and making informed choices around the “general” events of terrorism.

The purpose of this paper is to show the evaluation of the learning process to determinate if engineering student marks would be better from sand-table teaching than from traditional teaching.

The innovative teaching project incorporating digital sand-table use was evaluated by asking undergraduate and postgraduate students to rate their learning experiences and by analyzing their academic performance.

The results show that the percentage of students passing the courses, and marks on the course tests were higher for students taught using sand-table, compared to students taught without using this tool.

Engineering curricula are constantly revised to address the demands for undergraduate courses and specialization courses, and the differing needs of actual practice in relation to theoretical knowledge.

The experience at the University of Córdoba (Spain) offers some insights to other engineering degrees and educational institutions that wish to focus on the development of innovative academic programs and student capabilities.

The paper aims to propose a multi-criteria model for risk prioritisation associated to supply chain management involving multiple decision-makers.

The model integrates the composition of probabilistic preferences (CPP) on the failure modes analysis and its effects (FMEA) criteria. First, the authors carried out a probabilistic transformation of the numerical evaluations of the multiple decision-makers on the FMEA criteria regarding the internal risks that affect the chain of clothing pole in the Agreste region of Pernambuco. Then, the authors proposed the use of the Kendall's concordance coefficient W to aggregate these evaluations.

Contrary to expectations, the two main risks to be investigated as a model suggestion was related to the context of supply chain suppliers and not related to the raw material costs. Besides, a simulation with the traditional FMEA was carried out, and comparing with the model result, the simulation is worth highlighting seven consistent differences along the two rankings.

The focus was restricted to the use of only internal chain risks.

The proposed model can contribute to the improvement of the decisions within organisations that make up the chains, thus guaranteeing a better quality in risk management.

Establishing a more effective representation of uncertain information related to traditional FMEA treatment involving multiple decision-makers means identifying in advance the potential risks, providing a better supply chain control.

This research seeks to discover how the organisational form (franchising vs vertical integration) of 384 fashion stores belonging to a Spanish franchise chain influences unit-level performance measured through three key indicators commonly used in the retail literature: sales per square metre, sales per employee and service quality scores.

The authors have analysed this research question using bivariate and multivariate analyses, with a panel dataset that includes quarterly establishment-level data covering the period from January 2018 to December 2019.

The aggregated data initially reveal weaker outcomes among franchised establishments. However, after controlling for other variables related to the fashion stores and their local markets, the authors have found that franchised establishments record higher sales both per square metre and per employee than vertically integrated stores. The findings also reveal that franchised establishments record lower service quality scores than their company-owned counterparts.

Nothing has been published on the differences between franchising and company ownership in terms of establishment-level performance in fashion retailing.

The purpose of this study is to explore communication of hazard-resistant construction techniques after disaster in the absence of outside influence. It further aims to unpack the barriers and drivers in the adoption of knowledge processes to identify strategic recommendations to enlarge adoption of safer construction practices by local construction actors.

This paper is based on an analysis of stakeholders’ perspectives during post-disaster reconstruction in the Philippines in the province of Busuanga after Typhoon Haiyan in 2013. Data were collected from six communities that received no external housing assistance, analyzing surveys from 220 households, 13 carpenters, 20 key actors coordinating reconstruction or recovery efforts, as well as 12 focus group discussions.

This research argues for a stronger role of governmental agencies, vocational training schools and engineers. Current communication of typhoon-resistant construction knowledge is ineffective to stimulate awareness, understanding and adoption by local construction actors and self-recovering households.

The analysis in this study focuses on a small sample of communities in the west of the Philippines that are not frequently affected by typhoons.

This is one of the few scholarly works in the Philippines focused on adoption of safer construction practices by community-based construction actors when technical housing assistance is absent.

Digital natives constitute a substantial part of consumers nowadays. Yet, a theoretical understanding of the factors driving their engagement with new-age digital services is lacking. This study therefore aims to examine digital natives’ continuance usage of the proliferating over-the-top (OTT) services. To address these objectives, the study uses a comprehensive model that primarily integrates perceived value, cognitive absorption and customer brand engagement theories.

Data were collected using an online personal questionnaire targeting active digital natives OTT service users using the online software tool SurveyMonkey. A sample of 1,415 digital natives was analysed using structural equation modelling.

The findings indicated that continuance usage is predicted by all three theories. The results illustrate that cognitive absorption and customer brand engagement are the most critical in enhancing continuance usage. Gender effects on digital natives’ value perceptions were found. The model explains 57% of the variance in users’ continuance usage.

The study adds valuable contributions to the existing literature that are relevant to digital natives’ engagement with new-age digital services. The proposed integrated model and the role of gender in value formations provide managers with novel insights when designing effective strategies to increase continuance usage for the largest consuming generation.

This paper develops novel proxies for labour tax avoidance (LTAV) and tests their validity within a sample of 189 labour tax-avoidant offending firms (LTAOFs) accused of evading social security contributions (SOCs) by public authorities.

LTAV proxies are based on abnormal values of SOCs paid, reported in the income statements of a sample of 857,790 Spanish firm-years for the period 2001–2015, estimated through two-stage least square panel data regressions with firm fixed effects.

The results reveal that proxies specifically built to signal both conforming and non-conforming LTAV can provide evidence of abnormally low SOCs as expenses within the sample of LTAOFs. Furthermore, firm-specific financial variables as well as macroeconomic variables significantly influence LTAV.

This study could foster further research on the efficacy of the LTAV proxies and on the drivers and sustainability implications of LTAV for firms and their stakeholders in different socio-economic and institutional contexts.

These LTAV proxies could integrate other methods applied to estimate the undeclared work and its trends. Furthermore, they may assist tax authorities to direct their inspections, detect labour tax evasion and then strengthen the social protection of the employees from employers' illegal exploitation practices, as well as reducing tax revenue shortfalls and related sustainability concerns in the social security systems.

This study proposes a novel methodology to examine LTAV and its determinants through accounting information. This methodology may support researchers to provide a more comprehensive picture of tax planning strategies pursued by companies, that include LTAV, and in this way integrate the extant mature literature on income tax avoidance.
