In the context of signed line graphs, this article introduces a modified inflation technique to study strong Gram congruence of non-negative (integral quadratic) unit forms, and uses it to show that weak and strong Gram congruence coincide among positive unit forms of Dynkin type 𝔸n. The concept of inverse of a quiver is also introduced, and is used to obtain and analyze the Coxeter matrix of non-negative unit forms of Dynkin type 𝔸n. With these tools, connected principal unit forms of Dynkin type 𝔸n are also classified up to strong congruence.

As IoT applications are pervasively deployed across multiple domains, the potential impact of their security vulnerabilities are also accentuated. Sensor nodes represent a critical security vulnerability in the IoT ecosystem as they are exposed to the environment and accessible to hackers. When compromised or manipulated, sensor nodes can transmit incorrect data which can have a damaging impact on the overall operation and effectiveness of the system. Researchers have addressed the security vulnerabilities in sensor nodes with several mechanisms being proposed to address them. This paper presents DAM (Detect, Avoid, Mitigate), a theoretical framework to evaluate the security threats and solutions for sensor security in IoT applications and deployments. The framework leads to the classification of sensor security threats and categorization of available solutions which can be used to either detect vulnerabilities and attacks, recover from them or completely avoid them. The proposed framework will be useful for evaluating sensor security in real-world IoT deployments in terms of potential threats and designing possible solution

Research conducted within the wider theoretical framework of Dik’s Functional Grammar has resulted in important contributions to linguistic typology, and, vice versa, empirical facts from a wide variety of languages have significantly improved the theory of Functional Grammar, especially regarding its typological adequacy. This article discusses the following contributions to Linguistic Typology: the development of a sound sampling methodology, classification of noun categories (Seinsarten), an account of (so-called) number discord, the introduction of the new grammatical category of ‘nominal aspect’, a new typology of classifiers, and a universal concerning the occurrence of adjectives as a distinct word class. Conversely it will be shown that facts from many different languages have played an important role in the development of a layered model of the noun phrase in Functional Grammar and how currently these facts are used to test hypotheses concerning parallels between NPs and clauses.

Paradoxical performance can be described simply as a sudden decrease in a top athlete’s performance despite the athlete’s having striven for superior performance, such as the lost-skill syndrome in trampolining or “the yips” in golf. There is a growing amount of research on these phenomena, which resemble movement disorders. What appears to be missing, however, is a clear phenomenology of the affected movement characteristics leading to a classification of the underlying cause. This understanding may enable specific diagnostic methods and appropriate interventions. We first review the different phenomena, providing an overview of their characteristics and their occurrence in sports and describing the affected sports and movements. We then analyze explanations for the yips, the most prominent phenomenon, and review the methodological approaches for diagnosing and treating it. Finally, we present and elaborate an action theoretical approach for diagnosing paradoxical performance and applying appropriate interventions.

Service Framework

With the increasing diffusion of Internet of Things (IoT) technologies, the transportation of goods sector is in a position to adopt novel intelligent services that cut across the otherwise highly fragmented and heterogeneous market, which today consists of a myriad of actors. Legacy systems that rely upon direct integration between all actors involved in the transportation ecosystem face considerable challenges for information sharing. Meanwhile, IoT based services, which are designed as devices that follow goods and communicate directly to cloud-based backend systems, may provide services that previously were not available. For the purposes of this paper, we present a theoretical framework for classification of such intelligent goods systems based on a literature study. The framework, labelled as the Intelligent Goods Service (IGS) framework, aims at increasing the understanding of the actors, agents, and services involved in an intelligent goods system, and to facilitate system comparisons and the development of new innovative solutions. As an illustration of how the IGS framework can be used and contribute to research in this area, we provide an example from a direct industry–academia collaboration.

Conceptual Meaning

A qualitative, contextual, exploratory and descriptive design for theory generation was used to develop a model to facilitate reflective thinking in clinical nursing education (Mouton & Marais, 1990:43; Mouton, 1996: 103- 109; Chinn & Kramer 1991:79-120). A model was developed within the existing frameworks of theory generation. Wilson (1963:23-39) and Gift (1997:75,76) provided a theoretical framework for a concept analysis of reflective thinking in phase one of the study. Further conceptual meaning was attained through a perceptual survey where twelve nurse educators participated in a focus group interview with regard to how reflective thinking can be facilitated in clinical nursing education. Classification of the main concepts and sub-concepts was made through a conceptualisation process within Dickoff, James and Wiedenbach’s (1968:415-435) theoretical framework using the six elements of practice theory.

AbstractThis paper proposes a theoretical framework for the conceptualization and design of help options in computer-based second language (L2) listening. Based on four empirical studies, it aims at clarifying both conceptualization and design (CoDe) components. The elements of conceptualization consist of a novel four-part classification of help options: operational, regulatory, compensatory and explanatory. The design section establishes ways that make help options easy to use, encourage learner control, frame guidance and stimulate learning. Each component is contextualized, discussed and presented with limitations and suggestions for further research.

Hazard identification in the construction industry is subject to a larger number of variables and unknowns than in other manufacturing industries making the hazard identification process more difficult and resulting in many injuries and fatalities. Moreover, previous research identified a research gap with regards to a universal hazard identification method. The results presented in this paper are a prerequisite for the development of such a method. Specifically, this paper proposes a novel classification of hazards in order to enable a more accurate hazard identification process which can take all possible hazards into consideration. Based on the theoretical framework, three hazard types are proposed in the research: self-induced hazards, peer-induced hazards, and global hazards. This classification is based on who is the source (who causes) the hazards in relation to who is affected by the hazards. Such classification was not identified in previous literature. This research also has practical implications. Such classification of hazards may influence safety experts to more actively focus on peer-induced hazards which are the hardest to identify. Finally, the outputs of the entire research should enable a more accurate and comprehensive hazard identification resulting in reduced injury and fatality rates in the construction industry.

Different Levels

“Farmer Giles of Ham” is a satirical story by J. R. R. Tolkien. It is full of humour and allusions. The diversity of these elements allows for a detailed linguistic study distinguishing different levels at which the humour can be found and the different ways in which it is achieved. In the present paper, we attempt to discuss these devices and levels of humour and draw some conclusions on their effects. Our study is reinforced by a discussion of theoretical preliminaries of humour analysis, including the classification of the different levels, forms and devices of humour, as well as a brief discussion of the most widely acknowledged theory of humour ‒ the incongruity theory. Using this theoretical framework, we explore the possibilities of viewing the phenomenon of humour in literature from a linguistic perspective and attempt to show the utility of this perspective in literature studies.
