Market participants form conceptualizations of the products exchanged within product markets. Strategy scholars have begun to investigate how these product conceptual systems influence firm strategic behavior. Much of this work characterize these concepts as categories and theorize that the strategic implications derive from the potential penalties of not fitting into a category. This view has limitations in that it does not fully address the other cognitive tasks that concepts perform as well as other system-level characteristics of the conceptual systems. This chapter addresses these limitations by framing the use of concepts as part of the interpretive processes that enable market exchange. It develops a system-view of product concepts and then shows how the structure of the product categorical system influences the interpretation of product concepts. It introduces new mechanisms centered on cognitive processing that influence strategic action within product markets.

The expression of conceptual syntagmatic relationships in document retrieval systems holds out hope for both increased discrimination (generally) and increased recall (in certain contexts). The inclusion of such relationships in retrieval systems requires both a structured inventory of relationships and some means of expressing them; this article examines the latter. To be fully effective, the expression of conceptual syntagmatic relationships must comply with criteria of systematicity, complexity, efficiency and naturalness. Unfortunately, the complex interaction of natural language means of expressing these relationships (lexicalisation, word order, function words and morphosyntactic cases) causes them to fail the systematicity criterion. Most document retrieval system means of expressing conceptual syntagmatic relationships (as exemplified by various term co‐occurrence techniques, links and role indicators) fail to comply with this and other of the criteria. Only gestalt structures simultaneously representing relationships, participants and roles (for example, frames) conform fully to the criterial checklist.

The main purpose of this study is to offer a critical review of studies of scientific progress of strategic management (SM) research in the hospitality and tourism field (H&T).

This study was conducted through a critical literature review based on three dimensions: intellectual, conceptual and social structures of SM research.

The boundaries of SM under the three dimensions (intellectual, conceptual and social structure) are addressed. Based on these three components, SM in hospitality and tourism realm shows a discursive structure. There are few studies assessing the evolution of SM research in the H&T industry. However, all of these studies are review papers that explored the boundaries of SM research in H&T by using limited keywords to find SM papers, and generally considered papers which are published in a few leading H&T journals.

This study focused on only H&T journals to elaborate the boundaries of SM in H&T. The findings of this study can help researchers (re)design research agendas to contribute to both mainstream and H&T industry SM literature and to enhance the essential elements of theory development in SM research related to H&T industry.

This is one of the first studies assessing the development of SM research related to hospitality and tourism by considering the boundaries of SM in three issues: intellectual, conceptual and social structure.

This paper presents a new solution for conceptually modeling the training‐domain knowledge of intelligent computerassisted instructional (ICAI) systems. Various cognitive demands from learners impose various modalities of presenting and structuring the knowledge to be taught. This paper is presenting a theoretical framework allowing to develop coherent, flexible models for the training‐domain knowledge of an ICAI system. A case study and an authoring‐system are also presented, in order to describe the main features of the modeling methods. This new approach in ICAI systems’ domain‐knowledge structuring and representation can offer a solution to the problem of adapting the instructional system interaction to users with different learning styles and needs.

The lightweight design of aircraft seats can significantly improve fuel efficiency and reduce greenhouse gas emissions. Metal additive manufacturing (MAM) can produce lightweight topology-optimized designs with improved performance, but limited build volume restricts the printing of large components. The purpose of this paper is to design a lightweight aircraft seat leg structure using topology optimization (TO) and MAM with build volume restrictions, while satisfying structural airworthiness certification requirements.

TO was used to determine a lightweight conceptual design for the seat leg structure. The conceptual design was decomposed to meet the machine build volume, a detailed CAD assembly was designed and print orientation was selected for each component. Static and dynamic verification was performed, the design was updated to meet the structural requirements and a prototype was manufactured.

The final topology-optimized seat leg structure was decomposed into three parts, yielding a 57% reduction in the number of parts compared to a reference design. In addition, the design achieved an 8.5% mass reduction while satisfying structural requirements for airworthiness certification.

To the best of the authors’ knowledge, this study is the first paper to design an aircraft seat leg structure manufactured with MAM using a rigorous TO approach. The resultant design reduces mass and part count compared to a reference design and is verified with respect to real-world aircraft certification requirements.

The paper reports experimental results concerning user interaction with document organization, user‐librarian negotiation and the librarian's search processes in public libraries. The focus of the investigations is on the cognitive aspects of information retrieval. After defining the formal framework of the information retrieval (IR) process a theoretical section discusses the cognitive viewpoint on which the research is based, followed by an outline of applicable findings and theories within the fields of cognitive science and cognitive psychology. The experimental design involving tape‐recording and analysis of verbal protocols is briefly described and considered. The main part of the paper concentrates on the results of investigations and considers certain implications. It is shown how the user's knowledge structures cope with the structures of the system. User needs seem often to be presented as a label which may create ambiguity problems. Functions of open and closed questions are investigated and certain behaviouristic factors discussed. Matching the knowledge structure of the user and the librarian is considered a kind of learning process. Librarians prefer search activity before consideration of the presented problem. Without a user present the librarian's IR process is determined by three search attitudes involving motives and expectations as to search routines and possibilities. Conceptual knowledge, previous search and working domain play important roles. The attitudes have consequences for the objectives concerning use of routines and for the use of search concepts.

This paper seeks to develop a specified typology of various levels of semantic interoperability, designed to provide semantically expressive and functional means to interconnect typologically different sub‐systems in an international comprehensive knowledge organization system, supporting advanced information retrieval and exploration strategies.

Taking the analysis of rudimentary forms of a functional interoperability based on simple pattern matching as a starting‐point, more refined strategies to provide semantic interoperability, which is actually reaching the conceptual and even thematic level, are being developed. The paper also examines the potential benefits and perspectives of the selective transfer of modelling strategies from the field of semantic technologies for the refinement of relational structures of inter‐system and inter‐concept relations as a requirement for expressive and functional indexing languages supporting advanced types of semantic interoperability.

As the principles and strategies of advanced information retrieval systems largely depend on semantic information, new concepts and strategies to achieve semantic interoperability have to be developed.

The approach has been developed in the functional and structural context of an international comprehensive system integrating several heterogeneous knowledge organization systems and indexing languages by interconnecting them to a central conceptual structure operating as a spine in an overall system designed to support retrieval and exploration of bibliographic records representing complex conceptual entities.

Research and development aimed at providing technical and structural interoperability has to be complemented by a thorough and precise reflection and definition of various degrees and types of interoperability on the semantic level as well. The approach specifies these levels and reflects the implications and their potential for advanced strategies of retrieval and exploration.

Since, the middle of the 1990s, UNO has been funding a large‐scale project aimed at designing a family of natural language (NL) processing systems transforming the sentences in various NLs into the expressions of a new language‐intermediary called the Universal Networking Language (UNL) and vice versa. The purpose of the paper is to propose a constructive way of developing a semantic networking language (SNL) of a new generation and, as a consequence, to bridge a gap between UNL‐based studies and Semantic Web projects.

The methodological basis of the paper is a new theory of designing semantic‐syntactic analyzers of NL texts elaborated by the author of the paper and called the theory of K‐representations (knowledge representations). One of its basic components is a mathematical model describing a system of ten partial operations on conceptual structures and determining a new class of formal languages called restricted standard knowledge languages (RSK‐languages).

It is shown that the expressive possibilities of RSK‐languages surpass the expressive possibilities of UNL from the standpoint of representing the meanings of discourses, compound goals, descriptions of sets, definitions of notions. It is proposed to use the definition of the class of RSK‐languages as a model of a SNL of a new generation in comparison with UNL.

It is also proposed to use the definition of RSK‐languages for building semantic annotations of arbitrary web‐documents and web‐services.

The paper describes an original approach to representing conceptual structure of NL texts.

Aims to set systems thinking into the context of manufacturing systems management (MSM), which is defined as a functional domain that involves the necessary activities such as design, implementation, operations and monitoring, needed to regulate and optimise a manufacturing system as it progresses through its life cycle. Based on a number of key principles of systems theory, results from an extensive analysis of the relevant methodologies and techniques, and data gathered through industrial practice, a conceptual MSM framework is proposed. This framework specifies the key functional areas of MSM, outlines the contents and relationships within them, and then logically integrates these into a closed loop to provide the basis for the development of a set of consistent parameters and procedures. Its aim is to help achieve understanding of the problem domain, and to provide guidance for the development of effective mechanisms and tools for future MSM activities. A number of cases to illustrate its industrial application are also presented.

This paper aims to see how scholarly research on Greenwashing practices and behaviour has progressed in the 21st century. There has been a lot of empirical, exploratory and conceptual work done on Green marketing, sustainable marketing and environmental marketing. However, there have been few attempts to produce a comprehensive scientific mapping of Greenwashing as a niche topic. As a result, the study’s goal is to elicit research trends through knowledge structure synthesis.

A Bibliometric Analysis on the topic of Greenwashing practices was undertaken on 355 publications. For this, a scientific search strategy was run on the Scopus database for the period 1996–2021. The study was conducted using Biblioshiny, a Web-based application that is part of the Bibliometric package. Important journals, countries, authors, keywords and affiliations were found using the software’s automated workflow and thematic evolution, citations, co-citations and social network analysis were performed.

The study indicated a gradual increase in the research related to Greenwashing practices. The findings show a relative concentration of more influential work in the said domain amongst a handful of research scholars. Many influential studies have occurred after 2007, and a rally is seen in the studies on Greenwashing till 2020. The authors can say that the rigour of research has started increasing since then. Geographic dispersion of the work has shown that the USA followed by the UK dominates the scholarly inquiry and these countries have major collaboration with European and Asian researchers. The 10 most productive countries were examined, and it was discovered that the USA contributed the majority of the publications, with the UK and China coming in second and third place, respectively, in terms of publication in the said sector. In addition to the domain’s conceptual structure, the study exposes the domain’s social and Intellectual structure. This brings up new possibilities for Greenwashing studies in the future.

The present research is a Bibliometric analysis that is restricted to science mapping, and hence, limitations apply to the said studies. Researchers can use systematic literature review to build a robust conceptual foundation in the future. The Scopus database was used for this study because it has a greater number of high-quality journals in structured forms that are compatible with Bibliometrix software.

Greenwashing practices and behaviour, as well as their links to sustainability, are discussed in this paper. It highlights the most often stated challenges in the discipline and suggests possible research topics. It provides future scholars with information on this discipline’s issues, contexts and collaboration opportunities.

The current study can give further directions to the researchers for conducting rigorous research on Greenwashing behaviour and practices and will guide the policymakers to formulate policies in the field of non-sustainable activities, with Greenwashing being one of them.

A lot of work is done by the scientific community in Green marketing research, and a lot of literature is available on Green and Sustainable marketing practices. However, there is still a need felt for more extensive and rigorous research on the evolution of Greenwashing methods. This study makes a significant addition in that it brings together the scattered literature in the field, focuses on important sources, authors and documents, and investigates Greenwashing techniques and behaviour, which is the other side of the sustainable practices coin.
