Purpose The purpose of this paper is to propose a framework for data analytics where everything is grey in nature and the associated uncertainty is considered as an essential part in data collection, profiling, imputation, analysis and decision making. Design/methodology/approach A comparative study is conducted between the available uncertainty models and the feasibility of grey systems is highlighted. Furthermore, a general framework for the integration of grey systems and grey sets into data analytics is proposed. Findings Grey systems and grey sets are useful not only for small data, but also big data as well. It is complementary to other models and can play a significant role in data analytics. Research limitations/implications The proposed framework brings a radical change in data analytics. It may bring a fundamental change in our way to deal with uncertainties. Practical implications The proposed model has the potential to avoid the mistake from a misleading data imputation. Social implications The proposed model takes the philosophy of grey systems in recognising the limitation of our knowledge which has significant implications in our way to deal with our social life and relations. Originality/value This is the first time that the whole data analytics is considered from the point of view of grey systems.

Purpose This viewpoint study aims to make the case that the field of knowledge management (KM) must respond to the significant changes that big data/analytics is bringing to operationalizing the production of organizational data and information. Design/methodology/approach This study expresses the opinions of the guest editors of “Does Big Data Mean Big Knowledge? Knowledge Management Perspectives on Big Data and Analytics”. Findings A Big Data/Analytics-Knowledge Management (BDA-KM) model is proposed that illustrates the centrality of knowledge as the guiding principle in the use of big data/analytics in organizations. Research limitations/implications This is an opinion piece, and the proposed model still needs to be empirically verified. Practical implications It is suggested that academics and practitioners in KM must be capable of controlling the application of big data/analytics, and calls for further research investigating how KM can conceptually and operationally use and integrate big data/analytics to foster organizational knowledge for better decision-making and organizational value creation. Originality/value The BDA-KM model is one of the early models placing knowledge as the primary consideration in the successful organizational use of big data/analytics.

Purpose Dave Snowden has been an important voice in knowledge management over the years. As the founder and chief scientific officer of Cognitive Edge, a company focused on the development of the theory and practice of social complexity, he offers informative views on the relationship between big data/analytics and KM. Design/methodology/approach A face-to-face interview was held with Dave Snowden in May 2015 in Auckland, New Zealand. Findings According to Snowden, analytics in the form of algorithms are imperfect and can only to a small extent capture the reasoning and analytical capabilities of people. For this reason, while big data/analytics can be useful, they are limited and must be used in conjunction with human knowledge and reasoning. Practical implications Snowden offers his views on big data/analytics and how they can be used effectively in real world situations in combination with human reasoning and input, for example in fields from resource management to individual health care. Originality/value Snowden is an innovative thinker. He combines knowledge and experience from many fields and offers original views and understanding of big data/analytics, knowledge and management.

Purpose Many people in severe mentally disturbed states do not use language or other symbolic media well or coherently. Therefore, the non-verbal medium needs to be understood by workers with such people. The “Learning from Action” experiential workshop was developed in order to provide an opportunity to learn about hidden messages in the relationships and roles occurring in activities. In August 2017, a workshop was run for the first time in Japan. The purpose of this paper is to report the experience and dynamics observed by the three consultants, who are here the authors of this paper. Design/methodology/approach After the workshop all the staff and members, including interpreters, were invited to give feedback. Findings Analysis of the feedback data showed certain important dynamics, concerning especially dependence, cultural defences and the defensive role of activity in a multicultural context. Research limitations/implications This is an initial experience to be followed up by later feedback and further workshops. Practical implications Workers awareness of non-verbal communication within the roles of work activities is a training possibility. It faces various resistances including the mental health assumptions of meaninglessness of any communication outside the verbal. Originality/value This is a method of training not widely used even in European countries, and is the first in a country in the far east.

Purpose The purpose of this paper is to present a comparison between reluctance synchronous machine-enabling work at high internal temperature (HT° machine) with laminated and solid rotor. Design/methodology/approach To obtain heat sources for the thermal model, calculations of the electromagnetic field were made using the Opera 3D program including effect of rotation and the resulting eddy current losses. To analyse the thermal phenomenon, the 3D coupled thermal-fluid (CFD) model is used. Findings The presented results show clearly that laminated construction is much better from a point of view of efficiency and temperature. However, solid construction can be interesting for high speed machines due to their mechanical robustness. Research limitations/implications The main problem, despite the use of parallel calculations, is the long calculation time. Practical implications The obtained simulation and experimental results show the possibility of building a machine operating at a much higher ambient temperature than it was previously produced for example in the vicinity of the aircraft turbines. Originality/value The paper presents the application of fully three-dimensional coupled electromagnetic and thermal analysis of new machine constructions designed for elevated temperature.

The Relationship

Purpose – This article aims to test the relationship between expected attractiveness-satisfaction-loyalty for international adventure tourists visiting Tanzania. The proposed model is based on travel consumer behavior theoretical constructs extracted from the literature. Design/methodology/approach – This article aims to test the relationship between expected attractiveness-satisfaction-loyalty for international adventure tourists visiting Tanzania. The proposed model is based on travel consumer behavior theoretical constructs extracted from the literature. Findings – The findings for overall model differed from the moderating factors of high risk, low risk, first-time visit and repeat visit. Also, the results are interesting when satisfaction is tested as a mediator. Practical implications – Practitioners could consider the fact that repeat visits may change tourists’ perceptions toward destination and may even increase their inclination to take on risks. This may impact innovation of consumer products in tourism. Also, policy makers could benefit on how loyalty programs can be developed to increase performance. Originality/value – The study offers specific strategic recommendations toward different groups of tourists (i.e. first-time, repeat visitors, risk averse, risk seeking) and proposes logic for setting up a loyalty program as a long-term strategy for success.

Practical Implications

Purpose – The purpose of this paper is to analyse Michel Foucault’s new epistemological model regarding an analogy between the theory of language and economic thought in the seventeenth and eighteenth centuries. Design/methodology/approach – Through the scrutiny of language, Foucault intended to demonstrate that some analogies, among different branches of knowledge (interdiscursive practice), allow us to apprehend the underlying configuration of thought regarding ontological and epistemological conditions that have historically determined knowledge. He draws a parallel between four theoretical segments borrowed from general grammar (Attribution, Articulation, Designation and Derivation) and economic thought on wealth. Findings – One of the most remarkable propositions of this approach is that the theory of language and economic thought were epistemologically isomorphic in that context. What the theory of language stated in relation to “attribution” and “articulation” corresponded to the “theory of value” in economic thought. What grammar investigated regarding “designation” and “derivation” was analogous to the “theory of money and trade” in economic thought. The relationships that were – directly and diagonally – identified between and among them led to the conclusion that there was ‘a circular and surface causality’ in economic thought insofar as “circulation” preceded “production”. It was “superficial” because it could not find an explanation for the cause of “wealth”, which was only possible when “production” was placed in the front position of theories. Practical implications – Such an epistemological point of view can inspire other studies in the history of economic thought. Originality/value – This paper offers a perspective on how to think about the history of ontological and epistemological conditions of economic thought.

Good Manager

Purpose – This paper aims to look at the peripheral management practice that facilitates employee learning. Such management practices are embedded or inseparable to working and being a good manager. Design/methodology/approach – Point of view. Findings – For many frontline managers and their employees, the separation between working and learning is often not apparent. There appears to be no clear distinction between when they are working and when they are learning. Practical implications – Better development of organizational managers. Originality/value – This paper highlights the informal nature of learning and working and builds on the understanding that much of the learning that occurs at work occurs as part of a social act, often involving managers and their employees. In this way, employee learning that is identified and facilitated by frontline managers is so often entwined in other management activity. Furthermore, this paper outlines some practical actions that organizations can undertake to aid greater frontline management involvement in employee learning.

Purpose The purpose of this paper is to develop a novel network and dynamic data envelopment analysis (DEA) model for evaluating sustainability of supply chains. In the proposed model, all links can be considered in calculation of efficiency score. Design/methodology/approach A dynamic DEA model to evaluate sustainable supply chains in which networks have series structure is proposed. Nature of free links is defined and subsequently applied in calculating relative efficiency of supply chains. An additive network DEA model is developed to evaluate sustainability of supply chains in several periods. A case study demonstrates applicability of proposed approach. Findings This paper assists managers to identify inefficient supply chains and take proper remedial actions for performance optimization. Besides, overall efficiency scores of supply chains have less fluctuation. By utilizing the proposed model and determining dual-role factors, managers can plan their supply chains properly and more accurately. Research limitations/implications In real world, managers face with big data. Therefore, we need to develop an approach to deal with big data. Practical implications The proposed model offers useful managerial implications along with means for managers to monitor and measure efficiency of their production processes. The proposed model can be applied in real world problems in which decision makers are faced with multi-stage processes such as supply chains, production systems, etc. Originality/value For the first time, the authors present additive model of network-dynamic DEA. For the first time, the authors outline the links in a way that carry-overs of networks are connected in different periods and not in different stages.

Purpose – To explain the details and implications of a September 9, 2014 federal indictment, US v. Robert Bandfield, the first time a Foreign Account Tax Compliance Act (FATCA) violation has been charged as an “overt act” in furtherance of a tax conspiracy and securities fraud. Design/methodology/approach – Provides background, including the enactment of FATCA and the details of the indictment; describes an undercover investigation conducted by President Obama’s Financial Fraud Enforcement Task Force; and discusses the warnings this indictment sends to the global financial community. Findings – The indictment confirms the coordinated and aggressive tactics US law enforcement is now employing to investigate and prosecute offshore financial fraud. Practical implications – Banks and financial service providers need to be aware of the impact of enhanced US regulatory obligations and implement appropriate compliance measures. These institutions must also remain sensitive to risks presented by unscrupulous customers. Finally, they must be ready to manage appropriately information-gathering and investigatory inquiries originating with US authorities. Originality/value – Practical guidance from experienced tax controversy lawyers.
