Nested Context Language

Most multimedia documents available today are agnostic to data semantics. Moreover, their specification language offers little to ease authoring of meaningful content. In this paper, we present the main entities of a new version (3.1) of the Nested Context Model (NCM), which concentrate efforts at integrating support for enriched concept description to the model. These extensions enable the specification of relationships between concept descriptions and multimedia content in the hypermedia way, composing what we call hyperknowledge in this paper. NCM previous version (3.0) is a hypermedia conceptual model. NCL (Nested Context Language), which is part of international standards and ITU recommendations, was engineered according to NCM 3.0 definitions. The extensions discussed in this paper contribute not only for advances in the NCL, but mainly as a conceptual model for hyperknowledge document engineering.

Currently, advanced technological hardware can offer mobile devices which fits in the hand with a capacity to consult documents at anytime and anywhere. Multiple user context constraints as well as mobile device capabilities may involve the adaptation of multimedia content. In this article, the authors propose a new graph-based method for adapting multimedia documents in complex situations. Each contextual situation could correspond to a physical handicap and therefore triggers an adaptation action using ontological reasoning. Consequently, when several contextual situations are identified, this leads to multiple disabilities and may give rise to inconsistency between triggered actions. Their method allows modeling relations between adaptation-actions to select the compatible triggerable ones. In order to evaluate the feasibility and the performance of their proposal, an experimental study has been made on some real scenarios. When tested and compared with some existing approaches, their proposal showed improvements according to various criteria.

Relational Mapping

This paper describes a round-trip engineering approach for incrementally maintaining mappings between conceptual models and relational schemas. When either schema or conceptual model evolves to accommodate new information needs, the existing mapping must be maintained accordingly to continuously provide valid services. In this paper, the authors examine the mappings specifying “consistent” relationships between models. First, they define the consistency of a conceptual-relational mapping through “semantically compatible” instances. Next, the authors analyze the knowledge encoded in the standard database design process and develop round-trip algorithms for incrementally maintaining the consistency of conceptual-relational mappings under evolution. Finally, they conduct a set of comprehensive experiments. The results show that the proposed solution is efficient and provides significant benefits in comparison to the mapping reconstructing approach.

Language Environment

The process of studying a foreign language in Russian higher education institutions is carried out in a specially organized linguo-didactic language environment which is understood as a methodological framework designed in accordance with the peculiarities of a linguo-cultural community. It is aimed at combining learning methods and techniques to implement them into pedagogical practice, ensuring the level-by-level development of students’ language skills and complying with the international standards of language proficiency. The necessary modern basis for a linguo-didactic language environment is the use of Information and Communications Technology, which makes it possible to access the world of native speakers. The linguo-didacticlanguage environment creates socio-cultural communication patterns, provides an opportunity to become familiar with a different communication behavior, ensures students’ participation in real communication expanding the boundaries of language learning situations and enriching their communication experience. The attributes of the language environment include audiovisual materials, speaking practice, spoken and written language as well as cultural background knowledge and different learning components. The subjective attributes of the language environment include students’ cognitive activity, motivation and individual learning abilities. The conceptual model is aimed at teaching oral communication in a second foreign language in an artificial language environment which is based on the analysis and description of a current situation in the field of teaching a second foreign language at Russian universities, on perceiving a language situation as a basic education unit; on choosing the model of cross-cultural communication; on selecting the components of a natural language environment which have teaching potential and comply with the learning aims; on defining the learning methods; on creating the model of the designed environment.

Sustained Performance

We reviewed and summarize the extant literature on associative/dissociative cognitive strategies used by athletes and others in circumstances necessitating periods of sustained attention. This review covers studies published since a prior publication by Masters and Ogles (1998), and, in keeping with their approach, offers a methodological critique of the literature. We conclude that the distinction between associative and dissociative strategies has outlived its usefulness since initially proposed in an earlier era of ground-breaking research by Morgan and Pollock (1977) that was influenced to some extent by psychodynamic thinking. In recent years there has been an evolutionary shift in concepts of sustained attention toward mindfulness—moment-by-moment attention—that has had a significant impact on conceptual models and clinical practice in diverse areas including stress management, psychotherapy, and athletic performance. We propose that future research on cognitive activity in sustained performance settings be embedded in a mindfulness-based conceptual model.

Introduction. Intensive care units are systems organized for the provision of care to patients in critical situations. In general, it is suggested that intensive care consists of a multidisciplinary and interprofessional specialty. Nevertheless, the predominance, relative to the professions that incorporate these units, falls on nurses. A conceptual model of nursing provides a framework for reflection, observation, and interpretation of phenomena and, specifically, it provides guidelines and guidance for aspects of clinical practice. Objective. To understand the applicability of conceptual models of nursing in intensive care units. Method. Review of the literature following the Scoping Review protocol of the Joanna Briggs Institute. The research was performed in CINAHL, Cochrane, Pubmed, Scopus, and Web of Science to identify studies published prior to 2021. Fourteen studies were selected. Results. There is no conceptual model of nursing universally accepted as ideal for intensive care units. However, there is unanimity in the identification of several benefits associated with the application of a conceptual model of nursing in the care of critically ill patients. Conclusion. For the selection of a conceptual model of nursing for these contexts, the focus should be on the person and the choice should fall on the model that is most appropriate to the patient, and not on the philosophy that supports the model. Considering the nature of care, the nursing team can select a model or a combination of models.

Soft System Methodology (SSM) is common guidance to conceptualise Knowledge Management (KM) model since its benefit to handle complex situations. This study highlights SSM implementation on KM conceptual model using Systematic Literature Review (SLR) to produce insights about current implementation and promising chances in the future. This study also concerns on KM conceptual models as created without certain features in many case studies. Many various interpretation can arise to understand how system should work. This situation affected more spending time to validate KM conceptual model with stakeholders. Using SLR, this study criticises the importance of features as provided in eligible articles. Out of 144 articles from 2009 until 2019 as delivered from Scopus query, this study selected 12 articles about SSM on KM. It classified them into several criteria: published year, sector, and related KM life cycle. By mapping them to solve research questions, this study promoted actors, activities, and sequential order of activities as recommended features. By implementing them, KM conceptual model creation can be faster and accepted by stakeholders.

Conceptual modeling is currently considered a significant phase in information systems development. Several modeling grammars and methods have been studied extensively in the information systems discipline. However, previous research on conceptual models has focused on certain grammar (syntax) or discovering a way to deliver the meaning of a model (semantic) more clearly and completely. With regard to the construct overload issue in conceptual modeling, past studies have had some deficiencies in research methods and even presented contradicting results. The objective of the present study is twofold. First, the authors researched the interaction effect among syntax, semantics, and pragmatics to discover the preferred design, context, and user knowledge with which models are more likely to be understood or interpreted. Second, they performed an experiment to reconcile conflicting outcomes and acquire a more complete and accurate understanding of construct overload. Specifically, the authors focused on understanding the end users' modeling performance between ontologically clear and unclear models. They applied an improved experimental methodology that integrates three features (i.e., syntax, semantic, pragmatic) rather than treat them individually and employs different degrees of domain familiarity in the conceptual model (i.e., familiar domain vs. unfamiliar domain). The result of this study will broaden the perspective on usability in the context of the conceptual model and may serve as a modeler's ontological guidance in terms of whether or not to contain construct overload when they create a model. In addition, this study makes the theoretical contribution by verifying the domain extensibility towards the theory of ontological clarity.

This essay is the second of two essays about the use of a conceptual model to guide scoping reviews of literature. The first essay, published in the previous issue of Nursing Science Quarterly, provided examples of the use of the conceptual model of nursing and population health as a starting point for the construction of conceptual-theoretical-empirical structures for scoping reviews. In this essay, the examples are of the use of the conceptual model of nursing and health policy.
