Industrial simulations of turbulent flows often rely on Reynolds-averaged Navier-Stokes (RANS) turbulence models, which contain numerous closure coefficients that need to be calibrated. This paper aims to address this issue by proposing a semi-automated calibration of these coefficients using a new framework (referred to as turbo-RANS) based on Bayesian optimization.

The authors introduce the generalized error and default coefficient preference (GEDCP) objective function, which can be used with integral, sparse or dense reference data for the purpose of calibrating RANS turbulence closure model coefficients. Then, the authors describe a Bayesian optimization-based algorithm for conducting the calibration of these model coefficients. An in-depth hyperparameter tuning study is conducted to recommend efficient settings for the turbo-RANS optimization procedure.

The authors demonstrate that the performance of the k-ω shear stress transport (SST) and generalized k-ω (GEKO) turbulence models can be efficiently improved via turbo-RANS, for three example cases: predicting the lift coefficient of an airfoil; predicting the velocity and turbulent kinetic energy fields for a separated flow; and, predicting the wall pressure coefficient distribution for flow through a converging-diverging channel.

To the best of the authors’ knowledge, this work is the first to propose and provide an open-source black-box calibration procedure for turbulence model coefficients based on Bayesian optimization. The authors propose a data-flexible objective function for the calibration target. The open-source implementation of the turbo-RANS framework includes OpenFOAM, Ansys Fluent, STAR-CCM+ and solver-agnostic templates for user application.

We aimed to establish criteria for determining the deformed lateral torso type to identify individuals requiring measurement methods different from standard methods before extracting dimensions from three-dimensional (3D) scan data.

We collected the 3D body scan data of 119 women aged 70–85 years collected in the 6th Size Korea. Three axes were defined to determine the deformation of the lateral shape, and the angle of each reference axis was used for the analysis. Additionally, to classify the lateral torso shape, 14 experts made visual judgments on the side-view images of the participants.

To identify the axis that best represented the lateral torso shape, we used each angle value of the three reference axes as an independent variable and the expert’s visual classification as a dependent variable. Each discriminant function was obtained and accuracy calculated. The whole torso axis exhibited the highest accuracy. Next, an assessment scale was developed to determine the shape of the lateral torso using the angular value of the whole torso axis.

The scale developed in this study has the potential to reduce measurement errors arising from elderly deformed torso shapes, thereby enhancing data reliability.

Clause 1 [General Provisions] contains the provisions that in many contracts are bundled together under the ‘miscellaneous’ or ‘other provisions’ heading and includes a list of definitions, some interpretation principles, rules on communication between the Parties, documents forming the Contract, assignment, confidentiality etc. But Clause 1 also contains other provisions, like the Employer's right to use documentation and other deliverables provided by the Contractor (in other contracts usually referred to as a license to use), and a substantive Sub-Clause on limitation of liability.

The purpose of the project was to identify a mechanism of causal relationship between Brand Public Relations (BPR) and societal change in the perception of women gender roles.

Experimental evidence was obtained in three countries (N = 378) to examine the mechanism of societal impact of BPR. Effects of spillover of evaluations between two sub-brands of a house of brands company, caused by positive publicity about communication co-created by Public Relations (PR), were analysed.

Findings supported the existence of a positive spillover of evaluations. A mechanism of the societal impact of PR was also captured: an indirect effect of news stories about a non-objectifying portrayal of women in the male reference brand on the typicality of a non-stereotypical women role in society was demonstrated.

Experiments were conducted over a period of three years, during which publics perception of brands' communication about gender portrayal might have changed.

The paper argues for greater recognition of brand public relations professionals as co-creators of promotional brand communication. It gives evidence that one of the unique competencies of BPR is insight into publics and predicting long-term consequences of brand communication.

The findings of the research project suggest a mediated nature of influence of BPR on the perception of typicality of gender (women) roles in society. PR communicators should learn what areas of practice of PR require specific skills for the function of PR to develop the new competence.

This paper is the first one that aimed at establishing a common terminological framework of the societal impact of public relations.

The promotion of autonomous vehicles introduces privacy and security risks, underscoring the pressing need for responsible innovation implementation. To more effectively address the societal risks posed by autonomous vehicles, considering collaborative engagement of key stakeholders is essential. This study aims to provide insights into the governance of potential privacy and security issues in the innovation of autonomous driving technology by analyzing the micro-level decision-making processes of various stakeholders.

For this study, the authors use a nuanced approach, integrating key stakeholder theory, perceived value theory and prospect theory. The study constructs a model based on evolutionary game for the privacy and security governance mechanism of autonomous vehicles, involving enterprises, governments and consumers.

The governance of privacy and security in autonomous driving technology is influenced by key stakeholders’ decision-making behaviors and pivotal factors such as perceived value factors. The study finds that the governmental is influenced to a lesser extent by the decisions of other stakeholders, and factors such as risk preference coefficient, which contribute to perceived value, have a more significant influence than appearance factors like participation costs.

This study lacks an investigation into the risk sensitivity of various stakeholders in different scenarios.

The study delineates the roles and behaviors of key stakeholders and contributes valuable insights toward addressing pertinent risk concerns within the governance of autonomous vehicles. Through the study, the practical application of Responsible Innovation theory has been enriched, addressing the shortcomings in the analysis of micro-level processes within the framework of evolutionary game.

This paper investigates the relationship between prior planning and the practical adaptation and improvisation conducted by organizations during the COVID-19 pandemic through a qualitative case study of Norwegian Public Health Institutions.

This paper draws on a unique set of qualitative data, interviews and field observations, gathered from organizations during an ongoing crisis. Through this access it becomes possible to examine how organizations practically navigated the complex relationship between structured plans and the situational, short term forms of crisis communication.

The paper finds that prior plans played a key role as points of reference, and as a prior set of principles that could be drawn on during a crisis. Organizations did however have to adapt and respond to the crisis in ways that could not have been designed in advance. In order to do so employees would deliberate and discuss in search of a fitting response that could help them in reaching their goals.

The paper builds on prior work that has discussed limitations and challenges to planning and linear approaches in crisis communication and strategic communication, but provides empirical insight into how members of organizations navigate this work in practice. By employing theories from rhetoric it provides a framework for the further study of crisis communication as a practical ongoing activity, and provides some suggested implications for how organizations can prepare increase crisis preparedness.

This paper aims to explore how digital technologies can transform the museum into an “interaction platform” able to play a key role in the value co-creation processes of the tourism destination.

The paper applies the “co-creation through interactions” perspective by Ramaswamy and Ozcan. Empirically, the paper is based on the methodology of single case study identified in MArTA, the well-known National Archeological Museum of Taranto (South Italy). Data collection has been implemented through interviews with key informants and secondary data related to online interviews, press release and reports.

Findings provide empirical evidence about the contribution that a digitalization strategy can create a “museum as a platform” in which the interactions between the museum, its stakeholders and other co-creation elements (interfaces, artifacts and processes) bring benefits in terms of tourism experiences and sustainable development of the destination.

This research highlights the cultural changes and the actions that museum management has to implement to properly benefit from digitalization and to transform the museum into a reference point for reflection and innovation.

Elements of originality can be found in (1) the exploration of the wide spectrum of benefits and innovations that digital technologies can offer to the museum-mediated interactions and (2) the contribution to the understanding of the museum as a digitalized “interaction platform” capable of supporting the processes of co-creation of value in the complex network of actors and objects of a tourism destination.

Under the circumstances of the accelerated technological advance and the overlapping of various global crises in the recent years, one of the main strategic priorities of the European Union in medium and long terms consists of building resilient regional and local communities which implies the aim to protect citizens against the impact of climate changes. Considering the essential role of the human capital in this endeavor, this chapter aims to investigate the relationship between human resources and economic development focusing a SWOT analysis in the case of Romania taking into account recent developments and trends of the European and global labor market related to various aspects induced by the green transition. The analysis of the structural demo-economic characteristics of Romania’s population revealed a decline of the total population, against the background of negative demographic and net migration, the increase in the average and median age of the total population, the rise in demographic and economic dependency ratios representing serious challenges for the development strategy on short, medium and long terms. To these, increasing quantitative and qualitative shortages in the labor market are added, which complicate the advancement of the green transition in Romania. In the conclusions of this chapter, strategic milestones on policies and measures in the short, medium and long terms at macroeconomic and labor market levels are proposed.

This paper develops an evidence-based conceptual framework for exploring the applicability of choice architecture in business relationships.

Empirical studies of choice architecture in various fields are systematically reviewed to identify choice architecture techniques; major resulting categories of techniques are then discussed for applicability to business relationship contexts, and avenues for research are outlined.

Managerial decision-making is potentially influenced by changes to choice contexts that (1 provide additional information from outside the choice context, (2) facilitate a particular way of comparing options, (3) present options in new ways, (4) rework the choice set, e.g. by adding options and (5) create internal states that push toward a target choice.

The paper introduces the concept of choice architecture to business relationships. It develops a taxonomy of choice architecture techniques to guide the exploration of choice architecture effects in business relationships.
