Light field images (LFIs) have gained popularity as a technology to increase the field of view (FoV) of plenoptic cameras since they can capture information about light rays with a large FoV. Wide FoV causes light field (LF) data to increase rapidly, which restricts the use of LF imaging in image processing, visual analysis and user interface. Effective LFI coding methods become of paramount importance. This paper aims to eliminate more redundancy by exploring sparsity and correlation in the angular domain of LFIs, as well as mitigate the loss of perceptual quality of LFIs caused by encoding.

This work proposes a new efficient LF coding framework. On the coding side, a new sampling scheme and a hierarchical prediction structure are used to eliminate redundancy in the LFI's angular and spatial domains. At the decoding side, high-quality dense LF is reconstructed using a view synthesis method based on the residual channel attention network (RCAN).

In three different LF datasets, our proposed coding framework not only reduces the transmitted bit rate but also maintains a higher view quality than the current more advanced methods.

(1) A new sampling scheme is designed to synthesize high-quality LFIs while better ensuring LF angular domain sparsity. (2) To further eliminate redundancy in the spatial domain, new ranking schemes and hierarchical prediction structures are designed. (3) A synthetic network based on RCAN and a novel loss function is designed to mitigate the perceptual quality loss due to the coding process.

This paper addresses the growing fragmentation between traditional and digital service innovation (DSI) research and offers a unifying metatheoretical framework.

Grounded in service-dominant (S-D) logic's service ecosystems perspective, this study builds on an institutional and systemic, rather than product-centric and linear, conceptualization of value creation to offer a unifying framework for (digital) service innovation that applies to both physical and digital service provisions.

This paper questions the commonly perpetuated idea that DSI fundamentally changes the nature of innovation. Instead, it highlights resource liquification—the decoupling of information from the technologies that store, transmit, or process this information—as a distinguishing characteristic of DSI. Liquification, however, does not affect the relational and institutional nature of service innovation, which is always characterized by (1) the emergence of novel outcomes, (2) distributed governance and (3) symbiotic design. Instead, liquification makes these three characteristics more salient.

In presenting a cohesive service innovation framework, this study underscores that all innovation processes are rooted in combinatorial evolution. Here, service-providing actors (re)combine technologies (or more generally, institutions) to adapt their value cocreation practices. This research demonstrates that such (re)combinations exhibit emergence, distributed governance and symbiotic design. While these characteristics may initially seem novel and unique to DSI, it reveals that their fundamental mechanisms are not limited to digital service ecosystems. They are, in fact, integral to service innovation across virtual, physical and blended contexts. The study highlights the importance of exercising caution in assuming that the emergence of novel technologies, including digital technologies, necessitates a concurrent rethinking of the fundamental processes of service innovation.

The purpose of this paper is to explore the emergence of innovation in smart service systems to conceptualize how actor’s relationships through technology-enabled interactions can give birth to novel technologies, processes, strategies and value. The objectives of the study are: to detect the different enablers that activate innovation in smart service systems; and to explore how these can lead dynamically to the emergence of different innovation patterns.

The empirical research adopts an approach based on constructivist grounded theory, performed through observation and semi-structured interviews to investigate the development of innovation in the Italian CTNA (Italian acronym of National Cluster for Aerospace Technology).

The identification and re-elaboration of the novelties that emerged from the analysis of the Cluster allow the elaboration of a diagram that classifies five different shades of innovation, introduced through some related theoretical propositions: technological; process; business model and data-driven; social and eco-sustainable; and practice-based.

The paper embraces a synthesis view that detects the enabling structural and systems dimensions for innovation (the “what”) and the way in which these can be combined to create new technologies, resources, values and social rules (the “how” dimension). The classification of five different kinds of innovation can contribute to enrich extant research on value co-creation and innovation and can shed light on how given technologies and relational strategies can produce varied innovation outcomes according to the diverse stakeholders engaged.

Industry 4.0 defines the application of digital technologies on business infrastructure and processes. With the increasing need to take into account the social and environmental impact of technologies, the concept of Society 5.0 has been proposed to restore the centrality of humans in the proper utilization of technology for the exploitation of innovation opportunities. Despite the identification of humans, resilience and sustainability as the key dimensions of Society 5.0, the definition of the key factors that can enable Innovation in the light of 5.0 principles has not been yet assessed.

An SLR, followed by a content analysis of results and a clustering of the main topics, is performed to (1) identify the key domains and dimensions of the Industry 5.0 paradigm; (2) understand their impact on Innovation 5.0; (3) discuss and reflect on the resulting implications for research, managerial practices and the policy-making process.

The findings allow the elaboration of a multileveled framework to redefine Innovation through the 5.0 paradigm by advancing the need to integrate ICT and technology (Industry 5.0) with the human-centric, social and knowledge-based dimensions (Society 5.0).

The study detects guidelines for managers, entrepreneurs and policy-makers in the adoption of effective strategies to promote human resources and knowledge management for the attainment of multiple innovation outcomes (from technological to data-driven and societal innovation).

The purpose of this study is to conceptually integrate business to consumer (B2C) into business to business (B2B), with a holistic consumer-centric, technology-reinforced, long-term vision for tourism industries and companies to survive and succeed in the era of new technologies 4.0. The research suggests that the tourism-marketing-new technologies decision-making involves customers as the center of the design and decision process.

The research design includes a qualitative study with 94 in-depth interviews, a literature analysis and a conceptual proposition. The qualitative study follows the tourism consumer desire data analysis, from categorization to integration. The literature analysis applies a systematic literature review approach based on the 29 most up-to-date new-tech papers from peer-reviewed journals. The analysis compares qualitative research findings and literature analysis results and matches the new technology applications with consumer desire understanding. The conceptual framework of tourism marketing/advertising is proposed based on qualitative research and literature analysis.

The qualitative research deciphers that consumers, based on their imagination and memorization, desire therapy and sceneries and connect such desires to the empathetic and resonating advertising messages. The literature analysis synthesizes the new tech applications in tourism and matches the qualitative research findings with the deciphered desires in tourism. The conceptual model proposes that B2C should be integrated into B2B to provide value for both consumers and businesses and opens avenues of research on this topic.

This research has made the following theoretical contributions: it offers an in-depth understanding of consumer desire, often hidden or subconscious, in the field of tourism. Consumer desires regarding tourism are mostly subconscious and exist long before consumers are exposed to advertising messages. These desires reflect the search for therapy and sceneries and become “embodied” – they exist on multisensorial levels and become part of the body and life and will lead consumers into positive perceptions when marketing communications/advertisements resonate with them. In the latter case, they will subjectively judge advertising as “good,” regardless of the advertising design quality. The research also connects consumer research with a new technologies research review and proposes a conceptual framework to integrate business to consumer (B2C) with business to business (B2B). As such, the research makes theoretical contributions to the integration or the “boundary blurring” between B2C and B2B research and practical suggestions that involved industries and consumers may all benefit from such integration. Conceptually, there is a lack of discussions of the pitfalls of new technologies, a dearth of empirical verification of the applications of new technologies in the proposed fields and a shortage of discussions about ethical issues. Qualitative methods, offering an efficient tool for understanding consumer desires in the tourism industry, have their own limits, as discussed in previous research. The sample is limited to the state of New York population and may be influenced by geographic, demographic and psychological characteristics related to the region.

This research provides advertising practitioners, new technology innovators and tourism industries with a framework to face the combined challenges of understanding hidden consumer desires and applying adequate technologies that resonate with consumer desires to tackle relevant issues. The conceptual proposition of this research fills the gap between qualitative consumer research without concrete practical resolution and new technologies applications without in-depth consumer understanding. Through the conceptual framework, the author provides insights into how industries may benefit from consumer understanding. The business relationships among the industries of marketing, tourism and new technologies should be centered around consumers. Thus, B2C and B2B should be naturally integrated into business practices.

Social implications of this research include three major points: first, the understanding of consumer desire for therapeutic power in tourism, which invites more attention to tourism as part of social well-being design instead of a purely for-profit business. Second, a profound comprehension of what consumers need and desire, without which the applications of new technologies may cause severe societal problems. Third, a way to tailor to consumers’ individuality and desires for advertising/marketing that may be considered abusive, stressful and socially destructive if applied in a nonpersonal manner.

Conceptually, this research adds consumer desire, an originally B2C concept, to the B2B context regarding the new technology applications in tourism marketing/advertising. It contributes to the B2B literature by proposing a strong consumer-centric approach, especially the consumer desire understanding, that is not yet investigated in the B2B literature; and a combination of empirical study and literature analysis and the matching of the two for better practice of advertising/marketing, tourism and new technologies applications.

The aim of the paper is to propose an integrative model of the leader competences through the analysis of the several models of competence found in the literature review.

The methodology used was qualitative, based partially on an integrative literature review (Torraco 2016). This paper aims to review, update and criticize the literature related to the competences approach in the organizational context and, on the other hand, to review, criticize and synthesize the literature, namely, the models and competences.

Difficulties in choosing and implementing a leader competency model led to the integration of competencies in a single model, seeking to simplify the choice and implementation process in organizations. The integrative model of leader competences arises from the literature review, more specifically from the analysis of the different approaches found. This model is grouped into four dimensions – intellectual competences, management competences, social competences and emotional competences. This research is a contribution to reduce the fragmentation of leadership and management theories and facilitates the choice and implementation of a leader competence model suited to the organization’s needs, contributing to the leadership effectiveness.

The integrative model of the leader competences allows the choice and implementation of a competence model with a wide range of competences considered as essential in the organizational context by several researchers. This model simplifies the process of identifying the competences that need to be developed, feeding the human resources development process within the organization.

Business intelligence (BI) systems and tools are deemed to be a transformative source with the potential to contribute to reshaping the way different healthcare organizations’ (HCOs) services are offered and managed. However, this emerging field of research still appears underdeveloped and fragmented. Hence, this paper aims to reconciling, analyzing and synthesizing different strands of managerial-oriented literature on BI in HCOs and to enhance both theoretical and applied future contributions.

A literature-based framework was developed to establish and guide a three-stage state-of-the-art systematic literature review (SLR). The SLR was undertaken adopting a hybrid methodology that combines a bibliometric and a content analysis.

In total, 34 peer-review articles were included. Results revealed significant heterogeneity in theoretical basis and methodological strategies. Nonetheless, the knowledge structure of this research’s stream seems to be primarily composed of five clusters of interconnected topics: (1) decision-making, relevant capabilities and value creation; (2) user satisfaction and quality; (3) process management, organizational change and financial effectiveness; (4) decision-support information, dashboard and key performance indicators; and (5) performance management and organizational effectiveness.

To the authors’ knowledge, this is the first SLR providing a business and management-related state-of-the-art on the topic. Besides, the paper offers an original framework disentangling future research directions from each emerged cluster into issues pertaining to BI implementation, utilization and impact in HCOs. The paper also discusses the need of future contributions to explore possible integrations of BI with emerging data-driven technologies (e.g. artificial intelligence) in HCOs, as the role of BI in addressing sustainability challenges.

This study aims to dissect the multifaceted impact of ISO/IEC 17025 accreditation, specifically within civil engineering testing and calibration laboratories. To achieve this, it intends to explore several key objectives: identifying the prominent benefits of accreditation to laboratory performance, understanding the advantages conferred through participation in proficiency testing schemes, assessing the role of accreditation in enhancing laboratory competitiveness, examining the primary challenges encountered during the accreditation process, investigating any discernible adverse effects of accreditation on laboratory performance and evaluating whether the financial cost of accreditation justifies the resultant profitability.

This study employs a qualitative approach through semi-structured interviews with 23 industry professionals—including technical managers, quality managers, external auditors and clients. Thematic analysis, guided by Braun and Clarke’s six-stage paradigm, was utilized to interpret the data, ensuring a comprehensive understanding of the accreditation’s impact.

Findings reveal that accreditation significantly enhances operational processes, fosters quality awareness and facilitates continuous improvement, contributing to greater client satisfaction. In addition, standardized operations and rigorous quality controls further result in enhanced performance metrics, such as staff capability and measurement accuracy. However, the study also uncovers the challenges of accreditation, including high resource costs and bureaucratic hurdles that can inhibit innovation and slow routine operations. Importantly, the research underscores that the impact of accreditation on profitability is not universal, but contingent upon various factors like sector-specific regulations and market demand. The study also highlights sector-specific variations in the role of accreditation as a marketing tool and differing perceptions of its value among clients. It further emphasizes the psychological stress of high-stakes evaluations during audits.

This study represents the first in-depth investigation into the impact of ISO/IEC 17025 accreditation on civil engineering testing and calibration laboratories, directly contributing to the enhancement of their quality and operational standards. Providing actionable insights for laboratories, it underscores the importance of weighing accreditation costs and benefits and the necessity for a tailored approach to the unique market and regulatory landscapes they operate in.

The purpose of this study is to empirically explore how firms configure centrifugal and centripetal forces in promoting breakthrough innovation (BI), thus improving their strategic performance (SP) in the artificial intelligence (AI) context.

This study applies the centrifugal and centripetal forces model to a survey sample of 285 Chinese AI firms. Fuzzy-set qualitative comparative analysis (fsQCA) and propensity score matching (PSM) are integrated to explore the configurational effects of three centrifugal forces—the autonomy of technical experts, knowledge search and alliance network—and two centripetal forces—strictness of organisational institutions (SOI) and human–human–AI collaboration (HHAC)—on BI, examining whether the configurations that enhance BI can further improve SP.

The results indicate that the strictness of innovation institutions (SII) and strictness of ethical institutions (SEI) are equally important for determining SOI. Three configurations can improve BI when SOI and HHAC are the core conditions; only one of three configurations can further improve SP significantly.

By introducing SOI composed of equally important levels of SII and SEI and HHAC, this research is one of the few empirical studies to explore the mechanisms behind the impact of centrifugal and centripetal forces on BI and SP, which may help researchers and managers address innovation challenges in the AI context.

This paper aims to illustrate, by means of a content analysis of 278 weekly School Meeting minutes, the ways in which student voice is actualized in one democratic free school in Germany.

This paper uses a qualitative content analysis methodology of 278 weekly School Meetings minutes.

This paper uses Fielding’s (2012) patterns of partnership typology to illustrate what counts as student voice and participation in a democratic free school.

Limitations included being reliant on translations of German texts, some missing minutes from the entire set, the lack of a single author for the minutes (and thus degree of detail differs) and the fact that the School Meeting minutes make reference to other meetings for various sub-committees for which no minutes exist, and thus, findings on the degree of student voice may be limited. And because this is a study of one school, generalizability may be difficult. Future research into these sub-committee meetings would prove helpful as well as content analyses of other democratic free schools’ meeting minutes.

This study can help people more deeply understand what goes on in democratic free schools and what student voice and participation can mean within this context.
