This study redefines the ontological status of architecture through the framework of Lambros Malafouris's Material Engagement Theory (MET). Moving beyond paradigms that treat buildings as passive settings or symbolic forms, it argues that architecture operates as a macro-cognitive artifact—an active, constitutive participant in cognitive life. The investigation centers on Ryue Nishizawa's Moriyama House, a radically fragmented Tokyo residence that serves as an exemplary “theoretical probe” for tracing the dynamics of material engagement in situ. The analysis is structured around five core MET processes that illuminate the archaeology of cognitive behavior—the layered, historical emergence of thought patterns through material forms: (1) Thinging, or thinking-through-materials; (2) Enactive Signification, where meaning (like “privacy” or “gathering”) is not represented but performed through bodily engagement; (3) Participatory Agency, which co-constitutes action within human-nonhuman intra-actions (4) We-Intentionality, where shared goals materialize through triadic intra-actions among heterogeneous actors; and (5) Metaplasticity, the long-term, reciprocal reshaping of inhabitant habits and architectural wear. Employing a hybrid methodology of architectural analysis and frame-by-frame deconstruction of the ethnographic film Moriyama-San, the research demonstrates how these processes coalesce to form a cognitive habitat.

The role and embodiment of the designer/artist in making publics is significant. This special issue draws attention to reflexive practices in Art & Design, and questions how these practices are embedded in the formations and operations of publics, grounded in six cases of participatory design conducted in the United States, India, Turkey, England, Denmark, and Belgium. From these design practices, typologies of participation are formulated that describe the role of the designer. These typologies describe different and sometimes conflicting epistemologies—providing designers with a vocabulary to communicate a diversity of participatory settings and supporting reflexive practices.

This paper introduces a case study that involves data leakage in a bank applying the so-called Thinging Machine (TM) model. The aim is twofold: (1) Presenting a systematic conceptual framework for the leakage problem that provides a foundation for the description and design of a data leakage system. (2) The aim in (1) is developed in the context of experimentation with the TM as a new methodology in modeling. The TM model is based on slicing the domain of interest (a part of the world) to reveal data leakage. The bank case study concentrates on leakage during internal operations of the bank. The leakage spots are exposed through surveying data territory throughout the bank. All streams of information flow are identified, thus points of possible leakage can be traced with appropriate evidence. The modeling of flow may uncover possible hidden points of leakage and provide a base for a comprehensive information flow policy. We conclude that a TM based on the Heideggerian notion of thinging can serve as a foundation for early stages of software development and as an alternative approach to the dominant object-orientation paradigm.

This paper examines conceptual models and their application to computational thinking. Computational thinking is a fundamental skill for everybody, not just for computer scientists. It has been promoted as skills that are as fundamental for all as numeracy and literacy. According to authorities in the field, the best way to characterize computational thinking is the way in which computer scientists think and the manner in which they reason how computer scientists think for the rest of us. Core concepts in computational thinking include such notions as algorithmic thinking, abstraction, decomposition, and generalization. This raises several issues and challenges that still need to be addressed, including the fundamental characteristics of computational thinking and its relationship with modeling patterns (e.g., object-oriented) that lead to programming/coding. Thinking pattern refers to recurring templates used by designers in thinking. In this paper, we propose a representation of thinking activity by adopting a thinking pattern called thinging that utilizes a diagrammatic technique called thinging machine (TM). We claim that thinging is a valuable process as a fundamental skill for everybody in computational thinking. The viability of such a proclamation is illustrated through examples and a case study.

A conceptual model is used to support development and design within the area of systems and software modeling. The notion of validation refers to representing a domain in a model accurately and generating results using an executable model. In UML specifications, validation verifies the correctness of UML diagrams against any constraints and rules defined within the model. Currently, significant research has been conducted on generating test sets to validate that UML diagrams conform to requirements. UML activity diagrams are a specific focus of such efforts. An activity diagram is a flexible instrument for describing a system’s behaviors and the internal logic of complex operations. This paper focuses on the notion of validation using activity diagrams and contrasts that process with a proposed method that involves an informal validation procedure. Accordingly, this informal validation involves comparing requirements to specifications expressed by a diagram of a modeling language called thinging machine (TM) modeling. The informal validation is a type of model checking that requires the model to be small enough for the verification to be done in a limited space or time period. In the proposed method, the model diagram is divided into subdiagrams to achieve this purpose. We claim the TM behavioral model comes with a particular dispositional structure that allows a designer to “carve” a model into smaller components for informal validation, which is shown through two case studies.

Object tracking systems play important roles in tracking moving objects and overcoming problems such as safety, security and other location-related applications. Problems arise from the difficulties in creating a well-defined and understandable description of tracking systems. Nowadays, describing such processes results in fragmental representation that most of the time leads to difficulties creating documentation. Additionally, once learned by assigned personnel, repeated tasks result in them continuing on autopilot in a way that often degrades their effectiveness. This paper proposes the modeling of tracking systems in terms of a new diagrammatic methodology to produce engineering-like schemata. The resultant diagrams can be used in documentation, explanation, communication, education and control.

A control model is typically classified into three forms: conceptual, mathematical and simulation (computer). This paper analyzes a conceptual modeling application with respect to an inventory management system. Today, most organizations utilize computer systems for inventory control that provide protection when interruptions or breakdowns occur within work processes. Modeling the inventory processes is an active area of research that utilizes many diagrammatic techniques, including data flow diagrams, Universal Modeling Language (UML) diagrams and Integration DEFinition (IDEF). We claim that current conceptual modeling frameworks lack uniform notions and have inability to appeal to designers and analysts. We propose modeling an inventory system as an abstract machine, called a Thinging Machine (TM), with five operations: creation, processing, receiving, releasing and transferring. The paper provides side-by-side contrasts of some existing examples of conceptual modeling methodologies that apply to TM. Additionally, TM is applied in a case study of an actual inventory system that uses IBM Maximo. The resulting conceptual depictions point to the viability of FM as a valuable tool for developing a high-level representation of inventory processes.

This article takes Martin Heidegger's well-trammeled essay \"The Origin of the Work of Art\" as an object of reflection, engagement, and redirective innovation in order to think design now. The approach taken rests upon reading Heidegger from the perspective of a very different context: our present. By implication, engaging his text becomes informed by contemporary political, cultural, and environmental circumstances and imperatives. Such a reframed reading of Heidegger is then able to be taken to the ongoing project of rethinking design, not least its relation to art.
