Adequate means for easily viewing, browsing and searching knowledge graphs (KGs) are a crucial, still limiting factor. Therefore, this paper aims to present virtual properties as valuable user interface (UI) concept for ontologies and KGs able to improve these issues. Virtual properties provide shortcuts on a KG that can enrich the scope of a class with other information beyond its direct neighborhood.

Virtual properties can be defined as enhancements of shapes constraint language (SHACL) property shapes. Their values are computed on demand via protocol and RDF query language (SPARQL) queries. An approach is demonstrated that can help to identify suitable virtual property candidates. Virtual properties can be realized as integral functionality of generic, frame-based UIs, which can automatically provide views and masks for viewing and searching a KG.

The virtual property approach has been implemented at Bosch and is usable by more than 100,000 Bosch employees in a productive deployment, which proves the maturity and relevance of the approach for Bosch. It has successfully been demonstrated that virtual properties can significantly improve KG UIs by enriching the scope of a class with information beyond its direct neighborhood.

SHACL-defined virtual properties and their automatic identification are a novel concept. To the best of the author’s knowledge, no such approach has been established nor standardized so far.

Chen, Mathieu and Bliese (this volume) propose a useful framework for conceptualizing, testing, and validating multi-level constructs. Their framework focuses on the differences in constructs that occur between individuals and groups. One key question arises with their approach: What happens if the validity of constructs is viewed as potentially varying not only between individuals and between groups but also within individuals and within groups? The focus on within-individuals and within-groups variations is called “frog-pond effects.” Based on such frog-pond effects, this chapter reconsiders the approach of Chen et al. and discusses some of the implications of adding this perspective to multi-level research.

Individuals are often stigmatized by virtue of their status on various dimensions and as a consequence, they typically evoke negative cognitions, affect, and emotions among observers. In addition, they are often the targets of both access and treatment discrimination in organizations. Thus, we present a model of the cognitive, affective, and cultural influences on stigmatization in organizations, detail how stigmatization affects human resource management processes and practices, and consider strategies that can be used to reduce the problems faced by stigmatized individuals in organizations.

The provision of value, as a marketing issue, is receiving increasing attention from managers and scholars. This attention, in combination with strong calls for better quantification and stronger measures in marketing, has lead to increased interest in the assessment, quantified where possible, of the provision of value through buyer–seller relationships. This paper identifies dimensions of value provision through relationships in business markets with specific emphasis on the intangible aspects of value, which are important to long-term competitive advantage. The provision of value to the seller is the prime focus in this paper. The paper discusses the meaning of both tangible and intangible relationship value and the interplay between them and notes the importance of assessing the intangible part of the value, particularly the part which derives from the human aspects of the relationship. Despite their importance, the human aspects of relationships and their contribution to value is a sparse topic among researchers. The paper compares and evaluates potentially useful relationship and value conceptualizations. The paper discusses studies of relationship value and then outlines the results of a recent line of empirical research into the provision of value by a buyer to a seller that utilizes a framework synthesized from the intellectual capital literature. This recent research conceptualizes the potential for a seller's relationship with a buyer to provide intangible value to the seller in terms of, first, the resources available in the buyer and second, the capabilities of the buyer's boundary personnel to aid in facilitating the flow of those resources to the seller. The paper also includes the softer human aspects in the dimensions of value. These latter aspects are important to a full assessment of value. The paper concludes with a discussion of aspects of intangible relationship value that need further elucidation and will thus provide opportunities for future research.

The essential investments in new product development (NPD) made by industrial companies entail effective management of NPD activities. In this context, performance measurement is one of the means that can be employed in the pursuit of effectiveness.

The conditions that are constantly changing and transforming by digital technologies in today's world have forced businesses to think strategically and to comply with the rules and processes of strategic management. Technologies, such as the internet of things, cloud computing, artificial intelligence, and big data, especially in the Industry 4.0 ecosystem, cause some conflicts or constructive and destructive effects on the management approaches and management strategies of businesses. Businesses need to understand these technologies and their effects to maintain their existence and manage their resources and capabilities effectively and strategically. In this chapter, it is aimed to examine the conflicts with destructive and constructive effects of digital technologies on the strategic management of enterprises. For this purpose, the literature was searched qualitatively, and a conceptual study was carried out. At the beginning of the chapter, strategic management literature was researched, and strategic management approaches and views were examined. In the next part, digital technologies in the Industry 4.0 ecosystem are explained. In the last part, digital technologies and their impacts in terms of strategic management approaches (position approach, resource-based approach, and complementing views of resources-based approach) have been examined.

Academic library consortia activity has become an integral part of academic libraries’ operations. Consortia have come to assert considerable bargaining power over publishers and have provided libraries with considerable economic advantage. They interact with publishers both as consumers of publishers’ products, with much stronger bargaining power than individual libraries hold, and, increasingly, as rival publishers themselves. Are consortia changing the relationship between academic libraries and publishers? Is the role of academic library consortia placing academic libraries in a position that should and will attract the attention of competition policy regulators? Competition policy prohibits buying and selling cartels that can negatively impact the free market on which the Canadian economic system, like other Western economies, depends. Competition policy as part of economic policy is, however, only relevant where we are concerned with aspects of the market economy. Traditionally, public goods for the greater social and cultural benefit of society are not considered part of the market economic system. If the activities of academic library consortia are part of that public good perspective, competition policy may not be a relevant concern. Using evidence gained from in-depth interviews from a national sample of university librarians and from interviews with the relevant federal government policy makers, this research establishes whether library consortia are viewed as participating in the market economy of Canada or not. Are consortia viewed by librarians and government as serving a public good role of providing information for a greater social and cultural benefit or are they seen from a market-economic perspective of changing power relations with publishers? Findings show government has little in-depth understanding of academic library consortia activity, but would most likely consider such activity predominantly from a market economic perspective. University librarians view consortia from a public good perspective but also as having an important future role in library operations and in changing the existing scholarly publishing paradigm. One-third of librarian respondents felt that future consortia could compete with publishers by becoming publishers and through initiatives such as open source institutional repositories. Librarians also felt that consortia have had a positive effect on librarians’ professional roles through the facilitation of knowledge building and collaboration opportunities outside of the home institution.

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.
