Abstract
Purpose
The purpose of this study was to develop and apply new physical heart defect models (PHDMs) that are patient-specific and color-coded with an optimized map.
Design/methodology/approach
Heart defect anatomies were segmented from medical images and reconstructed to form virtual models, which were then color-coded and rapid prototyped. The resulting PHDMs were used in a medical educational study to evaluate their pedagogical efficacy and in clinical case studies to investigate their utility in surgical planning.
Findings
A growing library of 36 PHDMs (including the most common defects) was generated. Results from the educational study showed that the PHDMs enabled uniquely effective learning, and the clinical case studies indicated that the models added value as surgical planning aids.
Research limitations/implications
The education study involved a limited number of students, so future work should consider a larger sample size. The clinical case studies favored use of the PHDMs in surgical planning, but provided only qualitative support.
Practical implications
Workflow optimization is critical for PHDMs to be used effectively in surgical planning because some operations must be performed in emergently.
Social implications
Because PHDMs have potential to influence surgeons’ actions as surgical planning aids, their use in that context must be thoroughly vetted.
Originality/value
The proposed models represent the first PHDMs that are patient-specific and fully color-coded with a standardized map optimized for the human visual system. The models enhanced medical education and facilitated effective surgical planning in this study.

Abstract
The progress of parallel computing in Information Retrieval (IR) is reviewed. In particular we stress the importance of the motivation in using parallel computing for text retrieval. We analyse parallel IR systems using a classification defined by Rasmussen and describe some parallel IR systems. We give a description of the retrieval models used in parallel information processing. We describe areas of research which we believe are needed.

Abstract
Purpose
This article explores brand positioning and authenticity within the global-local continuum, utilizing the evolution of the Italian rock band, Måneskin, as a case study.
Design/methodology/approach
Employing Greimas’s (1987) semiotic framework, I analyze social media and media articles on Måneskin’s success, unveiling consumer perceptions of global, local and intermediate brand positionings and related authenticity dimensions. I particularly uncover a narrative centered on “global” versus “local” brand positioning and their counterparts (i.e. “not global” and “not local”), forming a semiotic square.
Findings
In the “global” perception, the band is evaluated in terms of conforming to global standards, while, in the “local” understanding, the emphasis shifts to connections to local roots. In the “glocalization” perspective (global and local), the band’s activities are assessed concerning an integration between global conformity and local connections. The “glalienation” viewpoint (neither global nor local) is related to consistency, in the sense of being unique and avoiding a commitment to either global or local values. The data also highlight issues of inconsistency regarding brand positioning’s contradictions, such as the band’s incoherently merging local and non-local elements.
Originality/value
The proposed structural semiotics approach enriches previous theories by examining authenticity within global-local dynamics, offering insights into various authenticity dimensions and their interplay. It underlines shifts in authenticity perceptions and challenges binary brand positioning, advocating for strategic placement across the global-local continuum. Moreover, it emphasizes leveraging cultural elements and semiotics to effectively communicate authenticity.

Abstract
Purpose
An issue that tends to be ignored in information retrieval is the issue of updating inverted files. This is largely because inverted files were devised to provide fast query service, and much work has been done with the emphasis strongly on queries. This paper aims to study the effect of using parallel methods for the update of inverted files in order to reduce costs, by looking at two types of partitioning for inverted files: document identifier and term identifier.
Design/methodology/approach
Raw update service and update with query service are studied with these partitioning schemes using an incremental update strategy. The paper uses standard measures used in parallel computing such as speedup to examine the computing results and also the costs of reorganising indexes while servicing transactions.
Findings
Empirical results show that for both transaction processing and index reorganisation the document identifier method is superior. However, there is evidence that the term identifier partitioning method could be useful in a concurrent transaction processing context.
Practical implications
There is an increasing need to service updates, which is now becoming a requirement of inverted files (for dynamic collections such as the web), demonstrating that a shift in requirements of inverted file maintenance is needed from the past.
Originality/value
The paper is of value to database administrators who manage large‐scale and dynamic text collections, and who need to use parallel computing to implement their text retrieval services.

Abstract
Purpose
In this paper, we aim to understand why consumers often prefer products made using traditional practices even when products made using new practices are not of lower quality. We argue that this resistance, which we call “production process conservatism,” is heightened when the product is used in the performance of a social ritual.
Methodology
We develop this argument in the context of diamond jewelry, as consumers have generally been resistant to diamonds that are produced in laboratories, i.e., lab-created diamonds. Hypotheses were tested using experiments conducted with an online sample (Experiment 1) and with an MBA student sample (Experiment 2).
Findings
In Experiment 1, we find that married female respondents significantly prefer mined diamonds to lab-created diamonds when they are used as part of an engagement gift as opposed to a more routine gift. In Experiment 2, we find the same effect among women; in addition, the perceived risk associated with the ritual is found to mediate this production process conservatism.
Social Implications
This paper contributes to the understanding of a macrosocial phenomenon – acceptance of an innovation – by examining microinteractive processes in groups.
Originality/value of Paper
This paper develops an original theory that when individuals deviate from traditional aspects of rituals, they risk signaling a lack of commitment or cultural competence to the group even when such aspects are not explicitly stated.

Abstract
This study contributes to the limited literature dealing with ethical perceptions of earnings management in developing capital markets by investigating the perceptions of managers, accountants, and investment analysts in Malaysia, Singapore, Hong Kong and Thailand, to ethical issues concerning the management of earnings. The results are compared to similar studies undertaken in the US and UK. The results show that East Asian managers, accountants, and analysts tended to be less willing to condemn situations as clearly unethical and use a narrower range of ethical responses than their US/U K counterparts. However, there was a remarkable overall consistency of perceptions between East Asian and US/UK managers, accountants, and analysts in relation to many issues.

Abstract
The authors review the German voluntary turnover literature and examine how it reflects and extends the overall knowledge of employee turnover. First, the authors describe legal, institutional, and cultural influences specific to Germany that may affect voluntary turnover and its relationships with antecedents and outcomes. The authors then explain how research paradigms, which in German turnover research are primarily embedded in sociology and labor economics and to a lesser degree psychology and management, affect the lens by which voluntary turnover is examined. For instance, the variety of research perspectives leads to a variety of research questions, theories, data, and methodological approaches. Using these diverse perspectives, the authors explain how measurement and data quality concerns may hamper the understanding of turnover in cross-country/cross-cultural comparisons. This review further reveals many similarities with US-based turnover research, regarding the theories, methods, and results. The authors also find that turnover levels are, on average, considerably lower in Germany than in Anglo-Saxon labor markets. The authors suggest that the industry structure in Germany, coined by its strong and traditionally organized “Mittelstand” companies, may partly drive these findings. The authors close by identifying several research opportunities, available through advances in technology to improve the matching process, nonstandard work arrangements (such as in the gig economy), and a broader perspective on institutional peculiarities.
