The Common

The article presents a software architecture to optimize the process of prototyping and deploying robot controllers that are synthesized using model-based design methodologies. The architecture is composed of a framework and a pipeline. Therefore, the contribution of the article is twofold. First, we introduce an open-source actor-oriented framework that abstracts the common robotic uses of middlewares, optimizers, and simulators. Using this framework, we then present a pipeline that implements the model-based design methodology. The components of the proposed framework are generic, and they can be interfaced with any tool supporting model-based design. We demonstrate the effectiveness of the approach describing the application of the resulting synchronous dataflow architecture to the design of a balancing controller for the YARP-based humanoid robot iCub. This example exploits the interfacing with Simulink® and Simulink® Coder™.

Local Agent

Purpose – The purpose of this paper is to present a concurrent implementation of sustainable inventory for the UNESCO World Heritage sites of Bat, Al-Khutm and Al-Ayn in the interior of Oman. Design/methodology/approach – A digital heritage inventory (DHI) was developed through an action research to realize demands of the local agent and to co-design the solution. The Ministry of Heritage and Culture of Oman, the local agent, demanded to have archaeological information of the sites shared with foreign expeditions, which had worked at the sites for decades, for efficient heritage management, scientific research, outreach, and education. To this end, the Bat Digital Heritage Inventory (BatDHI) was implemented by a combination of network-access-ready database application, open source geographical information systems, and a web-based map service to incorporate and visualize previous works, which were concurrently cross-checked and updated by ground-truth surveys. Findings – The online inventory made it possible to update information during archaeological fieldwork in real time and accelerated the decision-making process in heritage management by prompt data updates and visualization. Research limitations/implications – The DHI is extendable for other sites or regions. It should also be considered to install Arches, an open-source suite of digital heritage inventories. Practical implications – The BatDHI was implemented through the action research mentioned in the design/methodology/approach section and yielded the implications mentioned in the findings section. Originality/value – This paper is a challenging application of transdisciplinary approach to the sustainable heritage management, in which researchers and societal stakeholders collaborate for co-design of research agendas, co-production of knowledge, and co-dissemination of outcomes.

Successful Integration

Purpose – The purpose of this paper is to detect and challenge generally accepted management and consulting practice in Mergers & Acquisitions (M&As). M&As have been an important issue in strategic management and corporate development for decades. The integration process of two separate entities has been found to be of importance, and has, accordingly, received a significant amount of attention by research, management and consulting literature. Based on these insights, managers tend to rely on well-established and generally accepted rules developed by practice and consultants that should support a successful integration process and the generation of value. Nonetheless, M&As’ efforts still often fail to create value. So is the common practice of the established drivers and beneficial consequences of the integration of M&As right, or do the experiences of consultants, companies and managers reveal something different? Design/methodology/approach – To understand these challenges, the authors spent four years studying M&A projects and subsequent integration processes of more than 400 companies that engaged in M&A efforts. The data derived from four survey-based quantitative studies among more than 430 CEOs, CFOs and other senior managers in the field of M&As and personal interviews that were conducted to get in-depth insights. Findings – This extensive research on the efforts and projects of M&As over many years and including many companies reveals that successful integration processes are complex, social and culturally dependent endeavors and that the application of commonly accepted and established principles oversimplifies and disregards the interdependencies. Originality/value – The present paper unveils four established principles concerning the successful integration after M&As as tenacious myths and provides more differentiated insights into value-destroying and value-creating mechanisms in M&As.

PurposeCryptocurrency markets are notoriously noisy, but not all markets might behave in the exact same way. Therefore, the aim of this paper is to investigate which one of the cryptocurrency markets contributes the most to the common volatility component inherent in the market.Design/methodology/approachThe paper extracts each of the cryptocurrency's markets' latent volatility using a stochastic volatility model and, subsequently, models their dynamics in a fractionally cointegrated vector autoregressive model. The authors use the refinement of Lien and Shrestha (2009, J. Futures Mark) to come up with unique Hasbrouck (1995, J. Finance) information shares.FindingsThe authors’ findings indicate that Bitfinex is the leading market for Bitcoin and Ripple, while Bitstamp dominates for Ethereum and Litecoin. Based on the dominant market for each cryptocurrency, the authors find that the volatility of Bitcoin explains most of the volatility among the different cryptocurrencies.Research limitations/implicationsThe authors’ findings are limited by the availability of the cryptocurrency data. Apart from Bitcoin, the data series for the other cryptocurrencies are not long enough to ensure the precision of the authors’ estimates.Originality/valueTo date, only price discovery in cryptocurrencies has been studied and identified. This paper extends the current literature into the realm of volatility discovery. In addition, the authors propose a discrete version for the evolution of a markets fundamental volatility, extending the work of Dias et al. (2018).

Seeking transparency makes one blind: how to rethink disclosure, account for nature and make corporations sustainable

PurposeFinancial and nonfinancial disclosures are still anchored to conventional notions of transparency, whereby corporations “push” information out to various stakeholders. Such information is now “pulled” from various sources and addresses aspects of corporate behavior that go well beyond those envisioned by the disclosure framework. This shift makes notions of values, measurement and accountability more fragmented, complex and difficult. The paper aims to bring the accounting scholarly debate back to what and how transparency can be achieved especially in relation to issues of social inequality and sustainability.Design/methodology/approachAfter an analysis of the limitations of current approaches to disclosure, the paper proposes a shift toward normative policies that profit of years of critique of positivism.FindingsDrawing on the notion of value-added, the paper ends with a new income statement design, labeled as Value-Added Statement for Nature, which recognizes Nature as a further stakeholder and forces human stakeholders to give voice, or at least acknowledge the lack of voice, for non-human actors.Originality/valueThe author proposes a shift in the perspective, practice and institutional arrangements in which disclosure occurs. Measurement and transparency need to happen in communication exercises, which do not presuppose what needs to be made transparent once and for good but define procedures on how to make fragmented, complex, multiple and volatile notions of value transparent. Income statements and accounting more in general is to be reconceived as a platform where stakeholders will have to continuously negotiate what counts as the common good in the interest of all, including Nature.

Practical Implications

Purpose It has recently become more acknowledged that there is a quality of “messiness” to the qualitative research process. The purpose of this paper is to introduce the fieldpath approach—a hermeneutically inspired framework—to account for the non-linearity, uncertainty and ambiguity of the research process. Design/methodology/approach This conceptual paper reviews how the scope of hermeneutics has been partly misunderstood. The paper discusses how the scope of hermeneutics has lately been expanded by works such as Günter Figal’s (2010) Objectivity: The Hermeneutical and Philosophy. Findings The fieldpath approach proposes that a heightened relation to materiality enables the messiness of the process to be preserved, while at the same time offering a way to find one’s footing in the midst of ontologically incomplete phenomena that are still—in a processual fashion—forming and becoming. Research limitations/implications This is a conceptual paper. In addition to the research mentioned here, more studies would be needed to legitimise, test and refine the approach. Practical implications Objectivity provides an additional criterion for researchers to lean on when facing the non-linearity and unexpected turns inherent in the qualitative research process. Social implications The stress on materiality involves an ethical dimension. Post-human ethics are concerned with the future environmental consequences and sustainability of the material world. The way that matter matters in our methodologies is of primary importance. Originality/value First, the paper emphasises that hermeneutics, contrary to the common perception, does offer criteria for evaluating between interpretations. Second, it introduces the notion of hermeneutic objectivity, which stresses the importance of materiality for interpretations. Third, it introduces the fieldpath approach, which, based on the previous criterion of hermeneutic objectivity, allows for the messiness of the research process, while also preserving a tight grip on the hermeneutic imperative of “understanding in a new way”.
