Purpose – Infrared thermography is increasingly being used to diagnose pathologies in buildings, such as façade defects. The purpose of this paper is to assess the results reproducibility and the equipment influence on the measurements. To do so, it was defined as case study the assessment of rendering delamination. Design/methodology/approach – Two infrared cameras of different makers were used to detect the presence of defects deliberately created in specimens. The tests were done in the laboratory with a heat source. The defects were detected through a temperature gradient between the zones with and without defect. Findings – With this thermographic imaging, it was possible to identify the defects in the specimen both qualitatively and quantitatively. The results were found to be reproducible in the three cycles performed. The influence of the equipment on the results was of little significance for the quantitative assessment criterion “temperature difference between zones with and without defect”, but for the criterion “absolute surface temperature”, the difference in the results yielded by the two cameras was around 1.8°C. Originality/value – The results suggest that there is reproducibility of the measurements, considering both the qualitative and quantitative approach, when assessing delamination, irrespective of the maker of the equipment used. The influence of the equipment on the results depends on the quantitative assessment criterion used.

Purpose The purpose of this is to explore the potential of the combined use of the viable system model (VSM) and social network analysis (SNA) to identify organizational pathologies. Design/methodology/approach Using a well-documented case study based on an academic consultancy intervention and Action Research Project, participative methods for the diagnostic of the VSM and questionnaires for the collection of connectivity data for the SNA were used to develop a heuristic to integrate these two tools and identify organizational pathologies. Findings This study provides empirical evidence of the benefits of the combined use of SNA to enhance the identification of organizational pathologies in VSM interventions, by providing an additional qualitative and quantitative framework for the interpretation of findings coming from VSM organizational diagnostics. Research limitations/implications This work explores some analytic routines of SNA frequently used in management. The validation is constrained to the nature of the data set from a case study. The document invites to a discussion of further and more advanced applications on the integration of the VSM and SNA. Practical implications The enhanced identification of organizational pathologies can contribute to the emerging new interest in applications of the VSM in management, providing robustness to the structural analysis of organizations. Originality/value This paper proposes a guideline to exploit the potential of the combined use of SNA and VSM. It opens new avenues for the study of organizational pathologies.

Purpose – The purpose of this paper is to draw a picture on the reality of furniture industries in relation to management practices for project design of new products. Design/methodology/approach – In order to do so it was developed a multiple case study in three companies of the sector located in Santa Maria, Rio Grande do Sul. This study was based on verification criteria focussing on project’s lifecycle. Findings – As a result, it was possible to detect major faults from the organizations examined, it was found that processes are analyzed in a non-formalized and non-standardized way and, thus, restricting the integration of the projective stages, which reduced the quality of the final product. Originality/value – From the results obtained in the multiple case study, it was possible to propose actions managerial characteristics that demonstrate the process of design of new products as a result of an operational standard, integrated with the management practices of the organization.

Purpose This paper aims to attempt to tie in specific events into the case of Linde v. Arab Bank to provide a greater context. This case is the first where a US court held a bank civilly liable for providing financial support to a terrorist organization, but to do so, the court had to decide on several factors, involving as follows: the application of the anti-terrorism act; the sufficiency of evidence; and the causation of the plaintiffs’ damages. Design/methodology/approach This paper is a case study of Linde v. Arab Bank. It also takes an in-depth view of one particular terrorist attack that was alleged to have been financed by Arab Bank PLC. This paper reviewed similar legal cases, law review articles on the subject, congressional and government reports, congressional testimony and open source news involving the case and the terrorist incidents involved. Findings The court, in this case, ruled in favor of holding Arab Bank liable for money laundering and terrorist financing, which allowed American families to sue the bank for the loss of their loved ones. Originality/value This paper focuses on a unique issue involved in money laundering and terrorist financing. It is not fully a legal paper or a traditional academic paper. It is also unique in that case studies are rare in criminal justice and criminology journals.

PurposeThis article aims to investigate the most applied lean warehouse practices in Brazilian warehouses.Design/methodology/approachTo perform this research, three phases were conducted: a literature review, a multiple case study, and an analysis of lean warehouses practices implementation by an engineering committee. Thus, both qualitative and quantitative approaches were used. Additionally, the study has an applied nature, with an exploratory and descriptive character.FindingsResults showed that regardless of the type of criterion used, the most implanted practices are those that do not involve investments in technology. On the other hand, practices like RFID and Cross Docking systems were not found in any of the operations, which shows numerous possibilities for improvement.Originality/valueThe main contribution of this article is to initiate a debate about the management and productivity of Brazilian warehouses, a theme still little explored by the academic community despite the importance that the logistic scenario represents for Brazil as an emerging country and leader in Latin America, participating actively in several global supply chains.

Purpose – Conventionally, participation in the informal economy has been explained by viewing citizens as rational economic actors participating when the pay-off is greater than the expected cost of being caught and punished, and thus tackled by raising the sanctions and risks of detection. Given that many citizens do not engage even when the benefits outweigh the costs, a new social actor approach has begun to emerge which explains the informal economy as arising when tax morality is low and seeks to foster commitment to compliance. The purpose of this paper is to provide an evidence-based evaluation of these competing policy approaches. Design/methodology/approach – To do so, the results are reported of 1,306 face-to-face interviews undertaken during 2013 in the UK. Findings – The finding is that raising the sanctions and risks of detection has no significant impact on the likelihood of participation in the informal sector. However, participation in the informal economy is significantly associated with tax morality. Indeed, the only time that increasing the sanctions and risks of detection reduces the level of participation in the informal economy is amongst citizens with very low tax morality. Practical implications – Rather than continue with the current rational economic actor approach of increasing the penalties and risks of detection, this case study of the UK reveals that a new policy approach is required that seeks to improve tax morality by introducing measures to reduce the acceptability of participating in the informal economy. Whether this is more widely applicable now needs to be tested, given the dominance throughout the world of this punitive rational economic actor approach. Originality/value – This paper provides evidence supporting a new social actor approach towards explaining and tackling participation in the informal economy.

Purpose This paper aims to develop a better understanding of intergenerational knowledge transfer (IKT) practices by adopting a context-related and comparative perspective. Design/methodology/approach A qualitative case study design involving 83 interviews and non-participative observation in German and Quebec organizations has been chosen. Findings Two distinctive archetypes of IKT emerge from both national contexts: “we-individualizing” (Germany) and “I-connecting” (Quebec), leading to an eightfold taxonomy of IKT practices. Research limitations/implications This research is limited to young and senior workers and to high-tech sectors. Originality/value Comparative and inductive study of IKT, adaptation of IKT practices to national contexts, retaining younger workers. This inductive and comparative study allows a better adaptation of IKT practices to national contexts and therefore a better retention of younger workers.

Purpose The purpose of this paper is to discuss the role of digital forensics in an evolving environment of cyber laws giving attention to Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC) countries, comprising Bangladesh, India, Myanmar, Sri Lanka, Thailand, Nepal and Bhutan, in a dynamic global context. Design/methodology/approach This study uses a case study approach to discuss the digital forensics and cyber laws of BIMSTEC countries. The objective of the study was expected to be achieved by referring to decided cases in different jurisdictions. Cyber laws of BIMSTEC countries were studied for the purpose of this study. Findings The analysis revealed that BIMSTEC countries are required to amend legislation to support the growth of information technology. Most of the legislation are 10-15 years old and have not been amended to resolve issues on cyber jurisdictions. Research limitations/implications This study was limited to the members of the BIMSTEC. Originality/value This paper is an original work done by the authors who have discussed the issues of conducting investigations with respect to digital crimes in a rapidly changing environment of information technology and deficient legal frameworks.

Purpose With the increase of state capital, corporate total factor productivity (TFP) has a tendency to jump up at first and then slowly decrease. Generally, no significant “productivity paradox” can be observed in China’s manufacturing industry. With the increase of export density, corporate TFP also shows a trend of initial jump growth and subsequent slow decline. This paper aims to discuss these issues. Design/methodology/approach Using the 1996–2013 China Industrial Enterprise Database, this paper studies the monopolistic behavior of Chinese manufacturing enterprises through the measurement of TFP and corporate monopoly power. Findings Results show that China’s manufacturing monopoly enterprises are generally innovation-oriented rather than rent-seeking. However, there are certain differences between diversified types of monopoly enterprises: the ones with state capital are more inclined to innovate than those without, whereas the ones with export delivery value are more inclined to seek rent than those without. Originality/value Therefore, the government should implement differentiated policies for diversified types of monopoly enterprises, and do so in a targeted manner fully reflecting the containment of rent-seeking and the encouragement of innovation.

Purpose – The purpose of this paper is to lay the groundwork for a narrative study of desistance that is both qualitative and quantitative. Design/methodology/approach – The review traces the strands of research that have made self-story an important theme in the study of desistance with particular reference to work since 2001. Findings – The importance of an agentic self-story in the process of desistance from crime came to prominence in the work of Shadd Maruna (1997, 2001). Since then authors have attempted to formulate: first, an integrated theoretical view of desistance incorporating agency; and second, a clinically useful understanding of how self-story is important. The clinical studies have almost always been qualitative, relying on extensive life history interviews which yield great richness of detail but few, if any, testable hypotheses. To date, such studies have not provided the empirical foundation on which to develop policy in correctional environments. Practical implications – If it is found that a measure of self-belief correlates with desistance from crime, it may be possible to devise psychological interventions to enhance and change self-belief. Originality/value – The paper proposes adding a quantitative approach to the measurement of self-concept in order to estimate the likelihood of desistance.
