Mental constructions for the learning of the concept of vector space

AbstractThis study contributes to the literature on linear algebra instruction by designing and researching a teaching sequence based on APOS Theory to introduce engineering students to vector spaces. The sequence offers students multiple opportunities to understand the concept. Another contribution is the evidence that introducing prerequisite concepts—such as equality, sets, and binary operations—before tackling vector space was crucial for grasping the role of proof in determining whether a set is a vector space. The findings confirm that, as other studies have shown, vector space is challenging for students. However, the results demonstrate that students were able to face this challenge. All students showed evidence of developing an understanding of the concept, with nine achieving a clear grasp of vector space and the role of proof by the end of the experience. Additionally, the progress observed—from having difficulties with symbols to successfully proving statements involving unconventional operations—underscores the effectiveness of the teaching approach.

A Conceptual Design Method Based on Concept–Knowledge Theory and Large Language Models

Abstract To obtain innovative concepts in the design, designers often need to retrieve and use interdisciplinary knowledge. Concept–knowledge (C–K) theory emphasizes the role of knowledge and introduces the knowledge (K) space and concept (C) space, employing operators to transform the contents between these spaces. Some studies, based on this theory, have successfully provided designers with different forms of knowledge to stimulate concept generation. However, the amount of knowledge provided in these studies is limited, and they fail to offer convenient methods for knowledge retrieval and reasoning, making it challenging to meet the needs of conceptual design across different fields. This paper proposes an enhanced C–K method leveraging large language models (LLMs) to help designers retrieve knowledge and uncover potentially new concepts. Our method redefines the C space and K space within the context of LLMs, dividing the properties of concept into function, appearance, and technology, and requiring the knowledge to correspond to these properties, thereby facilitating a structured connection between concepts and knowledge. Based on this definition, we achieved flexible knowledge retrieval and concept ideation leveraging LLMs. We also conducted a case study on wearable devices to validate our method. The results showed that our method helped designers to retrieve professional knowledge and inspired them to create feasible and innovative concepts.

Enhancing Online Learning: Role Of Attention Detection Systems in Fostering Student Concentration

Online education is an inevitable trend. With just a smartphone, a tablet, or a personal computer, anyone, from teenagers to middle-aged individuals, from schoolchildren to workers, can access any free or paid courses in every aspect of society from economics, politics, literature, history, etc. foreign languages; Learners are free to choose lecturers, duration, time, space, and learning concepts as long as it suits their needs. However, online education still harbors many limitations, especially the issue of student distraction during online learning. This article elucidates the impact of online learning on student focus and analyzes the necessity of an attention detection system when studying online. Through surveys, the results indicated that up to 82.57% of students frequently lose focus when engaging in online learning, and 100% of opinions from education experts concur on the limitations of online learning. Based on these analyses, we provide insights into the necessity of developing and the crucial characteristics of an attention detection system to support learners in online education.

The Geometry and Dynamics of Meaning

AbstractAn enigma for human languages is that children learn to understand words in their mother tongue extremely fast. The cognitive sciences have not been able to fully understand the mechanisms behind this highly efficient learning process. In order to provide at least a partial answer to this problem, I have developed a cognitive model of the semantics of natural language in terms of conceptual spaces. I present a background to conceptual spaces and provide a brief summary of their main features, in particular how it handles learning of concepts. I then apply the model to give a geometric account of the semantics of different word classes. In particular, I propose a “single‐domain hypotheses” for the semantics of all word classes except nouns. These hypotheses provide a partial answer to the enigma of how words are learned. Next, a dynamic cognitive model of events is introduced that replaces and extends the function of thematic roles. I apply it to analyze the meanings of different kinds of verbs. I argue that the model also explains some aspects of syntactic structure. In particular, I propose that a sentence typically refers to an event. Some further applications of conceptual spaces are briefly presented.

On Some Dynamics in Conceptual Spaces

AbstractIn this text, we consider Gärdenfors’ conceptual spaces that are separable Hilbert spaces. In particular, the results we obtained apply to finite-dimensional Euclidean spaces. Our main contribution can be formulated as a combination of the theory of opinion dynamics with the theory of conceptual spaces. This combination, in turn, leads us to propose a new model for the time evolution of conceptual spaces. To achieve this goal, we propose some extension of the multidimensional opinion dynamics model of Parsegov, Proskurnikov, Tempo and Friedkin to opinions with values in Hilbert spaces.

Time in Heidegger’s Being and Time: A Reading

Heidegger’s concept of time in Being and Time emerges in critically engaging with his predecessor’s intellectual legacy. At the same time, however, his revolutionary idea of temporalty arising from what he calls a phenomenological destruction of the history of ontology is worth further scrutiny. Therefore, the following pages concern, first of all, investigating how Heidegger critically revises Kant’s and Hegel’s idea of time to propose his ecstatic temporality, by which he declares that the meaning of being is primarily conditioned by its temporality. What he calls fundamental ontology has the task of understanding being in terms of its temporality. To clarify this task, this paper focuses on Heidegger’s perspectival shift in understanding care from existential to ontological analysis. In doing so, it critically examines the process in which care is not fundamentally grounded in the self as much as in temporality. Lastly, this paper attempts to evaluate how Heidegger interprets public consciousness of time as it makes itself available in everydayness based on notions such as “datability” and “public time.” Heidegger’s emphasis on “punctuality” is significant as it is intended to criticize the linear notion of time reflected in Hegel’s concept of time and space. This paper wishes to remain loyal to reading Being and Time, except for a few cases if necessary.

Chemical Space for Peptide-based Antimicrobials.

Multidrug-resistant (MDR) bacteria represent a global public health threat, and antimicrobial peptides (AMPs), derived from naturally occurring linear or cyclic peptides, can provide the solution. However, most AMPs are sensitive to proteases and have poor pharmacokinetics. The EU-funded ERC Advanced Grant SPACE4AMPS aims to identify new AMPs by applying the concepts of chemical space and ligand-based virtual screening, which are well known for small molecule drug discovery, to the world of peptides. We create virtual libraries of peptides and related molecules and use these approaches to select a few tens of compounds for synthesis and detailed. evaluation of antibacterial, toxicity and stability effects. Recent results and prospects of this ongoing project are presented in this review.

Between the Religious and the Secular: Latin American Neo-Pentecostalism in a Context of Multiple Modernities

This article seeks to understand neo-Pentecostalism in Latin America as a religious and political movement within the framework of multiple modernities, based on an ethnographic study in evangelical churches in Chile and Mexico. The study focuses on two main axes: the discourse of the “Kingdom of God” and the experience of the Holy Spirit. The former explores the conception of public space, while the latter examines the experiential dimensions, both individual and collective, that confer meaning and legitimacy to this religious movement. Neo-Pentecostalism emerges as a complex phenomenon where religion and politics intertwine in novel ways, responding to the intricacies of the region. Contrary to the notion of a monolithic and reactionary movement, this article demonstrates how neo-Pentecostalism is a movement that navigates the interstices between the religious and the secular.

The Influence of Curatorial Art on Visual Art

As time progressed and societal structures underwent transformation, there was a notable increase in interest in the memories encapsulated by objects. This resulted in a significant increase in the development and popularity of museums and art exhibitions, which in turn gave rise to a multitude of innovative spatial art forms, and the term “curation” was born. This research program examines the impact of the curatorial space on the visual presentation of artworks and its role in the visual arts as a whole. This is achieved using an analysis of several specific cases. Moreover, it demonstrates the evolution and advancement of the utilisation of curatorial space for the presentation of artworks. The concept of curatorial space is both flexible and complex, with implications for both the visual arts and their presentation. The utilisation of new media and technology in curatorial environments has been demonstrated to offer several advantages over physical curation. These include enhanced accessibility, flexibility, and the capacity to reach a broader audience. Consequently, curators and artists are presented with the chance to interact with audiences and cultivate innovative artistic practices and prospects in the domain of digital media and technology.

Embedding Sustainability in Tourism Education: Bridging Curriculum Gaps for a Sustainable Future

The evolving challenges in the tourism industry, particularly those related to sustainability, demand significant revisions to current degree programs. This paper presents the design of a higher education curriculum for tourism studies at a Spanish university, responding to industry needs for broader, high-level knowledge and skills, with a strong emphasis on sustainability, digital transformation, and socially responsible practices. The curriculum prioritizes critical and strategic thinking alongside liberal reflection to empower students to lead in sustainable tourism development. Developed collaboratively with the entire tourism faculty, the curriculum design was informed by an extensive analysis of 105 international university courses, 204 job offers, feedback from 195 alumni, and ongoing consultations with professionals and community partners. Grounded in the concept of curriculum space and the philosophic practitioner framework, the curriculum integrates knowledge, soft skills, and attitudes to foster an innovative, sustainable learning ecosystem that prepares graduates to tackle the complexities of modern tourism with a focus on long-term environmental and social impacts.

Multiple dimensions of immorality

ABSTRACT We conducted a four-part study to map out the conceptual space of a diverse set of immoral items, including those that are extreme and/or intergroup (e.g. child sex abuse, genocide, slavery), with the goal of identifying attributes spontaneously used in moral judgment. In Part 1, we identified 56 immoral items. In Part 2, participants completed a similarity-based card sort task of the 56 immoral items. Multidimensional scaling (MDS) indicated that three-dimensional space was needed to capture the perceived differences among the items. In Part 3, regression analysis indicated that perceived similarity among the immoral items related to their commonness, objectivity, forgivability, and legality. In Part 4, regression analysis indicated that the configuration of immoral items corresponded to the amount of anger and disgust the items elicited and items’ perceived harmfulness. We attempt to synthesize these results and answer questions about the roles of anger, disgust, and harm in moral judgment.

Economic cyber-physical space: theoretical and methodological genesis and modern trends of formation and development

In this scientific study, the socio-economic and technical and technological features of the new economic and technological paradigm are high lighted. As a result of the analysis of trends in the development of the Industry 4.0 market and digital initiatives adopted in the world, the prerequisites for the formation of an economic cyber-physical space at the national level have been identified, and the relevance of the subject of scientific research has been substantiated. Based on the analysis of the evolutionary development of spatial economics, the research of scientific schools is systematized and theoretical and methodological schemes belonging to representatives of the German, French (continental), Anglo-Saxon and Russian schools of spatial economics are analyzed. As a result, the postulates of the economic cyberphysical space are developed and the author's interpretation of the concept of economic cyber physical space is proposed.

Mapping Data to Concepts: Enhancing Quantum Neural Network Transparency with Concept-Driven Quantum Neural Networks

We introduce the concept-driven quantum neural network (CD-QNN), an innovative architecture designed to enhance the interpretability of quantum neural networks (QNNs). CD-QNN merges the representational capabilities of QNNs with the transparency of self-explanatory models by mapping input data into a human-understandable concept space and making decisions based on these concepts. The algorithmic design of CD-QNN is comprehensively analyzed, detailing the roles of the concept generator, feature extractor, and feature integrator in improving and balancing model expressivity and interpretability. Experimental results demonstrate that CD-QNN maintains high predictive accuracy while offering clear and meaningful explanations of its decision-making process. This paradigm shift in QNN design underscores the growing importance of interpretability in quantum artificial intelligence, positioning CD-QNN and its derivative technologies as pivotal in advancing reliable and interpretable quantum intelligent systems for future research and applications.

Void Almanac: A Political-Geologic Rubbing of Nuclear Testing in Mississippi

Although classical physics states that the void lacks matter or energy, the misunderstanding of emptiness as a spatial concept extends far beyond the sciences. The essay explores the concept of empty space, debunking classical physics’ notion of voidness by delving into quantum mechanics, where energy and particles continually manifest through a site investigation of the Salmon & Sterling Nuclear Test Site (located in Lumberton, MS, USA). This revelation challenges colonial ideologies, exemplified by terra nullius, which justified empire-building by claiming certain lands devoid of inhabitants. Operating through a political-geological exploration of repetitive cycles of extraction, speculation, and vacancy at the Salmon & Sterling Site spanning from the Mesozoic Era to the present day, I scrutinize spatial constructions and their reinforcement of prevailing socio-political systems. Juxtaposed against Faulkner’s Southern Gothic literature and Sartre’s existentialism, this essay underscores a modern dialectic between spatial arrangements and anticipations of cataclysmic endings. Through a passenger-traveler account of void-encounter, I propose a reconsideration of “emptiness” through examining its broader spatio-temporal origins and implications in relation to the nuclear detonations. This perspective allows for the synthesis of the inherent paradox of this site: initially conceived from Cold War anxieties to solidify social structures, yet also harboring unpredictable and potentially mutant futures.

A városi zöldövezetek jelentősége és romániai helyzete

With the expansion of cities, green spaces are becoming increasingly important, significantly enhancing people's quality of life on multiple levels. In her study, Cristina Humă addresses the concept of urban green spaces and examines the situation in Romania from a social policy perspective, highlighting their importance in sustainable urban development. The analysis indicates that green areas have started to increase in Romania, but many localities still do not meet European standards, emphasizing the need for further development.

Advocating a place-space duality for an accounting research agenda

PurposeThe paper proposes a place-space duality, rather than a dualism, for accounting research.Design/methodology/approachThe discussion is informed by the literature in human geography, which, while developing the concept of space, has made an important distinction between abstract space and place as a site of experiential learning and memory.FindingsThe lack of a concept of place is a serious omission in the accounting literature and perpetuates an abstract sense of space, which can restrict the scope of accounting research.Research limitations/implicationsThe paper calls for further research to study accounting in place and to explore both the collective and individual senses of place, as well as conscious and unconscious place associations. We recognise that there is limited prior accounting research on this topic and that there are challenges in conducting such interdisciplinary research, especially as there is a lack of common ground between research in human geography and accounting and little integration of the two literatures.Practical implicationsThe paper proposes an accounting research agenda based on a place-space duality, which reflects the strength of people-place relationships, including place identities, place attachment and place dependence.Originality/valueThe paper provides a critique of the conceptualisation of space in accounting research, identifies place-space as a duality (rather than a dualism) and suggests a novel distinction between studying accounting in context and in place.

The dual problem of space: Relative player positioning determines attacking success in elite men’s football

ABSTRACT The concept of space has been successfully modelled in football using spatiotemporal player data and Voronoi diagrams. Current approaches, however, are narrow in scope by focusing on an inter-team allocation of space to measure space control. The present work extends this widespread perspective with an intra-team application of the Voronoi diagram and its dual Delaunay triangulation to measure space management. Both models are leveraged to derive novel performance metrics, which assess how teams use triangular positioning and how players tie up defenders during attacks. The outcome of N = 128,187 attacking sequences from 306 elite men’s football matches is analysed using linear mixed-effects models to validate the proposed performance metrics. Results show that attacking success is characterized by player positioning which promotes forming of large triangles especially in ball proximity, whereas the overall number of triangles is of no relevance. Furthermore, players tie up more defenders and thus create free teammates more often during successful attacks. The results demonstrate that a new perspective on space is helpful to better quantify and understand the effect of space management and player positioning on attacking performance in football.

Epistemic politics in the decolonisation of the body of knowledge of engineering discipline

ABSTRACT This article is written within a conceptual space that considers engineering as a heteronomous discipline. In this context, we analyse how the state has intervened in the development of the body of knowledge of engineering discipline in a developing country in a process known as decolonisation and the political dynamism this has created. We take the case study of Kenya where the state has intervened in the development of engineering education by creating new universities with new schools to teach engineering. The expansionist education policy on the other hand raised questions of quality assurance. Particularly, who has the right to accredit engineering education became politically controversial question that was debated in courtrooms through litigations, on the floor of Parliament through legislations, and in the print media. These three form the multiple case study research based on document analysis in a situation where the regulator of engineering practice claims accreditation rights against universities themselves and the regulator of university education. The study reveals a fragile situation in a developing country where accreditation is construed as a matter of mandatory state regulation and recommends that developing countries should voluntarily rely on regional or, where possible, technical accreditors, instead of state regulators.

Kant a problematický pojem věci o sobě

The paper discusses Kant’s distinction between appearances and things in themselves, phenomena and noumena, and the problem of affection. The difference between appearances and things in themselves is understood as a methodological difference between two manners in which an object can be viewed: either as an appearance, or as a thing in itself. The author claims that this double-aspect view is a consequence of Kant’s conception of space and time as a priori forms of sensibility. The difference between phenomena and noumena, on the other hand, cannot be explained only by the double-aspect view; Kant understands it also as an ontological difference between two different kinds of objects. The paper concludes with a discussion of the problem of affection. The author claims that this problem is a pseudo-problem if we understand the difference between appearances and things in themselves as double-aspect view. Kant had maintained only an empirical affection. Passages in which Kant seems to advocate a transcendental affection can be brought in line with Kant’s critical philosophy.

What's emotion got to do with it? Reflections on the buildings of the Portuguese (Family) Courts.

Courthouses, as public edifices, serve as the physical backdrop for the administration of justice. Simultaneously, they are spaces inhabited and visited by a diverse array of court users, ranging from judicial professionals to litigants. This article explores the nuanced interplay between courthouse spaces and the emotional experiences they generate. It starts by surveying existing studies that examine such an intricate relationship. Then, and by drawing from a sample of interviews conducted across two distinct time periods (2010-2011 and 2017-2019) in Portugal, the article delves into the lived experiences of judges, prosecutors, and litigants. Their narratives provide a multifaceted view of the emotional experiences associated with the Portuguese (Family) Court buildings. To analyse these experiences, I turn to Henri Lefebvre's concept of lived space. Lived space refers to the emotions, memories, and interactions within a particular spatial context. Such dimension, in relation to courthouses, directly connects to the lived experience of legitimacy loss and low self-esteem affecting decision-making, on the one hand, and estrangement and rights' exclusion, on the other hand, felt by those subjects. By investigating how the spatial configurations of courthouses shape our emotions, we gain insights into the profound impact of such built environments on our understanding of the justice system, and the physical and symbolic obstacles in accessing it.
