Concept Of Space Research Articles

Forms of Life and Public Space

New words have found their way into the public sphere: we now commonly talk about “confinement”, “barrier-gesture” or “distancing”. The very idea of public space has been transformed: with restrictions on movement and interaction in public; with the reintegration of lives (certain lives) into the home (if there is one) and private space; with the publicization of private space through internet relationships; with the cities’ space occupied, during confinement, by so-called “essential” workers; with the restriction of gatherings and political demonstrations in public space. With these and other recent changes, it is imperative to revisit the concept of public space, which continues to be used as if it were self-evident, despite its profound transformation over the past few decades, in a process of realization and “literalization”. No longer just a comfortable metaphor for reasonable debates, public space has become a concrete reality in the 21th century. This transformation in the various phenomena, such as the occupation of squares and public spaces; the demand for spaces of conversation and expression for those without a voice; the transition of private matters into the public realm through verbal expression; and the expression and circulation of public issues within popular cultures. As a result, the question of public space is increasingly intertwined with that of private spaces, such as the home or individual subjectivities, forming an internal, logical relationship.

Correlation concept-cognitive learning model for multi-label classification

As a cognitive process, concept-cognitive learning (CCL) emphasizes the structured expression of data through systematic cognition and understanding, to obtain valuable information in the data. Although concept-cognitive learning has achieved good results in single-label classification tasks, it has not yet been applied to multi-label learning. The difficulty is that the existing concept-cognitive learning fails to effectively associate and utilize the structural relationships in the feature concepts and the multi-label concepts. In addition, in the face of complex multi-label datasets, it is difficult to obtain effective concepts for classification tasks. To solve these problems, this paper proposes a correlation concept-cognitive learning method and applies it to the multi-label classification (MLC) task. Moreover, the relationship between the feature concepts and the multi-label concepts is established by extent. On this basis, we comprehensively consider the extent relevancy and intent relevancy, and learn correlation concepts. In order to improve the classification precision, we construct correlation concept spaces to obtain the representation of effective concepts. Finally, we conducted experimental evaluations on ten datasets to illustrate the effectivity and advantages of the proposed approach.

FandangObon: Amplification, counter‐publics, and fugitive spaces of belonging in Los Angeles

AbstractThe festive celebration known as FandangObon is made possible by workshops and satellite performances that artivistas (art activists) stage throughout the year in a variety of community venues. The event transforms the annual Japanese American Buddhist Obon ceremony honoring ancestors into an antiracist polycultural performance. Through improvisation and invention, colorfully adorned participants blend the dances, songs, and costumes of the Japanese bon odori circle with Mexican son jarocho fandango practices and West African ballet and egungun drum and dance circles. Each of the groups represented in FandangObon brings to the mix its own form of circle dancing, collective singing, and instrument playing, yet bon odori, fandango, and egungun do not fuse together seamlessly in these gatherings. Instead they coalesce as a conversation among equals in which each tradition remains faithful to itself in the process of making changes through engagement with others The concepts of amplification, counterpublics, and fugitive spaces of belonging serve in this article as central interpretive frames of a cultural critique of the historical and cultural conditions for the celebration's emergence, articulation, and implementation (Marcus and Fischer 1986).

Applying the third-place concept for transitional spaces in the Korean university using the design charrette approach

PurposeThis research investigates the impact of the COVID-19 pandemic on the use of transitional spaces in a Korean academic setting, to assess the impact of the pandemic on users' utilization of transitional spaces and evaluate any changes in their usage patterns. The research explores whether transitional spaces can function as social interactive spaces, aligning with Ray Oldenburg's “third-place” theory. The focus is on South Korean academic settings, aiming to create neutral and safe zones for users.Design/methodology/approachThe adopted methodology involves reviewing the literature and employing design charrette as a major data collection tool. The design charrette provided a platform for users to share insights on current transitional spaces during the pandemic and envision these spaces as future social and interactive spaces.FindingsThe design charrette participants advocated for modifying the current transitional space design to transform these spaces into shared spaces for both visitors and regular users in the future. Restricting access for external users to the main building area until necessary. The significance of site amenities in determining transitional spaces as “third-places” was emphasized. While the nature of the building, its location and transitional space amenities are crucial aspects to consider, designers may prioritize user opinions and preferences, as the success or failure of the design ultimately centers on user behaviors.Research limitations/implicationsThe research focused on a specific university, hindered by limited access to other institutions during the pandemic. Restrictions on external users discouraged entry without proper permission, which was challenging to obtain. The conventional design charrette outlined in the research method was impossible due to pandemic-related limitations on gathering participants in one location. Therefore, the researcher modified the design charrette method to align with strict social distancing measures.Social implicationsThe results of the research are not limited to academic settings, but they can be implied in other environments where social interaction spaces are required and where there is a constant flow of visitors and regular users. The design charrette can be used as a methodology for interior spaces along with large-scale projects of urban planning.Originality/valueThe research analyzed transitional spaces during the pandemic, suggesting redesign to serve and act as buffer zones between private and public areas and become a common social gathering place for visitors and regular users within the built environment.

«Безграничные объекты» экономической теории и эволюция представлений о пространстве

The paper considers the question of the evolution of the conception of economic space within the approaches of the classical school of the location of productive forces, the gravity model of international trade, the walrasian equilibrium model, as well as institutional analysis. Physicalist metaphors are considered in parallel with this evolution. It is emphasized that economic objects lack clear-cut boundaries, which leads to the problem of ignoring the heterogeneity of space. It is demonstrated that competition within the Walrasian space reduces the degree of heterogeneity, whereas the Coasian space is inherently heterogeneous. The changes in institutional regimes, blurring of property rights and specifying their identification can both decrease and increase transaction costs. it is inferred that the concept of boundaries of objects is of great importance to economic research.

Quasitopological vector spaces

In this paper, motivated by a diffeological vector space with the D-topology, we introduce the concept of quasitopological vector space, which is a vector space with a topology satisfying the conditions that the vector addition is separately continuous in each variable, and the scalar multiplication is jointly continuous. The following results are proved: (1) Every quasitopological finite-dimensional vector space is a topological vector space. (2) For each infinite-dimensional vector space, we define a T1 non-Hausdorff topology on it such that it is a quasitopological vector space but is not a topological vector space.

Regularized Nyström Subsampling in Covariate Shift Domain Adaptation Problems

The unsupervised domain adaptation problem with covariate shift assumption is considered. Within the framework of the Reproducing Kernel Hilbert Space concept, an algorithm is constructed that is a combination of the Nyström subsampling and the iterated Tikhonov regularization. This approach allows significantly reduce the amount of computing resources involved and at the same time achieves the minimal (by order) approximation accuracy under the big data settings.

Heuristics and semantic spaces for the analysis of students’ work in mathematical problem solving

In this research, our objective is to characterize the problem-solving procedures of primary and lower secondary students when they solve problems in real class conditions. To do so, we rely first on the concept of heuristics. As this term is very polysemic, we exploit the definition proposed by Rott (2014) to develop a coding manual and thus analyze students’ procedures. Then, we interpret the results of these analyses in a qualitative way by mobilizing the concept of semantic space (Poitrenaud, 1998). This detailed analysis of students’ procedures is made possible by collecting audiovisual data as close as possible to the students’ work using an action camera mounted on the students’ heads. We thus succeed in highlighting three different investigation profiles that we have named explorer, butterfly, and prospector. Our first results tend to show a correlation with these profiles and the success in problem-solving, yet this would need more investigation.

A mixed methods, longitudinal study: characterizing the differences in engagement and perceived learning of medical students in online and in-person team-based learning classes.

The rapid transition to online delivery of medical curriculum has facilitated the continuation of medical education during the COVID-19 pandemic. Whilst active learning approaches, including Team-Based Learning (TBL), are generally more supportive of the learner's needs during such transition, it remains elusive how different learning environments affect a learner's motivation, engagement, and perceived learning over a prolonged period. We leveraged on Self-Determination Theory (SDT) and key learners' characteristics to explore the levels of student's engagement and perceived learning in two TBL learning environments, online and in-person, over an extended period. We hypothesize that students' self-reported perceptions of engagement and learning will be lower in online compared to in-person TBL classes. This is a mixed methods study with 49 preclinical graduate medical students completing the same questionnaire twice for each learning environment, online TBL and in-person TBL, over an eight-month period. Quantitative data were collected on learners' characteristics, basic psychological needs satisfaction, motivation, student's engagement and perceived learning. The final questionnaire also explored participants' perception on which learning environment better supported their learning. We found that autonomy support, perceived competence and needs satisfaction, and perceived learning were higher in-person than online. Additionally, most learners felt that in-person TBL was better for learning, as the concepts of learning space and the community of practice were mediated by being in-person. TBL, being an active instructional method, can maintain students' engagement because it supports many aspects of SDT constructs and perceived learning. However, online TBL is unable to fully support the students' needs and perceived learning. Hence, we strongly advocate for any in-person opportunities to be included in a course, as in-person classes best supports students' engagement and perceived learning.

Establishing a Multi-Vial Design Space for the Freeze-Drying Process by Means of Mathematical Modeling of the Primary Drying Stage

Primary drying is the most critical stage of the freeze-drying process. This work aimed to establish a design space for this process by means of mathematical modeling of the primary drying stage, capable of addressing the thermal characteristics of distinct vial suppliers. Modeling of primary drying was implemented on Microsoft Excel using steady-state heat and mass transfer equations at two extreme conditions as assessed by risk analysis, to predict product temperature and primary-drying time. The heat transfer coefficients (Kv) of four different vial suppliers were experimentally determined, both, at the center and edge of the freeze-dryer's shelf. Statistically significant differences (ANOVA p<0.05) were observed between suppliers throughout the assessed pressure range. Overall, the average Kve/Kvc (edge/center) ratio was higher than 1.6 for all suppliers due to the radiation effect. A design space for the drying process was established using mathematical modeling taking into account the Kv of the worst-case supplier, in the shelf edge. A primary drying cycle was carried out at a shelf temperature of -25 °C and a chamber pressure of 45 mTorr for 8 % sucrose and at -10 °C and 75 mTorr for 5 % NaCl. Freeze-dried products with good cosmetic appearance were obtained for the four vial suppliers both, in the shelf center and edge. The results show that it is possible to predict and establish the critical parameters for the primary drying stage, under a design space concept, considering the differences in the Kv of vial suppliers without adverse consequences on the quality of the finished freeze-dried product.

Becoming temporarily protected, producing temporarily protecting places: how Syrian refugee women and children co-create place in Istanbul

ABSTRACT The paper examines the usefulness of the Deleuzian concepts of smooth space and stratified space while capturing the experiences of refugee women and children as non-citizens under the temporary protection regime in Istanbul. Deleuze and Guattari, in their book ‘A Thousand Plateaus’, describe smooth space as the territory of the nomads, those who do not fit in neatly into forms of identity and division. Striated space on the other hand is created by the sedentary, the state, with an interest in blocking the speed of flows, movements of elements not rooted in a supposedly homogenous whole. Many refugee children acquire by birth the legal status of being under temporary protection, a liminal position which for many turns into a life-long arrangement. How do refugee women and children re-create community and culture as bounded to a place? What kind of space delivers itself to being transformed into a place of belonging for them? To work through these questions, interview data from several Syrian women and three Syrian children gathered through semi-structured interviews are embedded in the observations of social workers and psychologists working at the Kizilay community Centre the informants frequent in the Bagcilar district of Istanbul Province in Turkey.

A calculative cosmography: Geodesy and absolute space

Visual signifiers of absolute space such as grids, points, and straight lines are often identified with absolute space as a concept, to the extent that critiques of one are taken to apply to the other. This article argues that this is a misidentification that forecloses attention to meaningful dimensions of the coordinate grid while muddling the concept of absolute space. Attending to the geodetic science that gives rise to these visual signifiers shows that the space they are used to construct is entirely relational, and that the mythless rationalism with which they and absolute space are commonly associated can be productively questioned through attention to geodesy’s performative and cosmological implications. This raises the question of how we might better understand absolute space. The suggested answer is a cosmological claim that can be pursued and pictured but never realized. Absolute space is absolute as a sovereign can be: neither empirically nor visually, but as a motivating idea that presents itself as an explanation.

Unraveling Trauma and Heterotopic Spaces in Michael Ondaatje's "Anil's Ghost": A Postcolonial Exploration

The present paper explores Michael Ondaatje's novel "Anil's Ghost" through the lens of trauma theory, postcolonialism, and the concept of heterotopic spaces. As space studies examine migration, displacement, and exile, which are inherently linked to traumatic experiences, the investigation illuminates the intricate connection between heterotopic spaces and encounters with trauma, providing a valuable understanding of their interdependence. Michael Ondaatje, the acclaimed author of "Anil's Ghost", has drawn upon his own traumatic experiences of displacement and emigration in the novel. Therefore, the purpose of the research paper is to analyze how changes in space shape traumatic experiences. Spaces are integral to one's sense of place and identity, and traumatic events might disrupt this connection, leading to a profound loss of identity or a struggle to reconcile personal identity with changed or disrupted spaces. Studying the connections between trauma and space reveals a better understanding of how environments and spatial contexts impact the occurrence, perception, and recovery from traumatic events. The research contextualizes Foucault's concept of heterotopia within postcolonial distinctions in time and space, emphasizing its relevance in understanding the novel's narrative. It highlights the complexity of trauma and the challenge of reconciling historical narratives within these spaces. Employing a multidimensional methodology integrating cultural studies, trauma theory, and literary analysis, results uncover the complexities of trauma within postcolonial spaces, notably Sri Lanka, showcasing the profound impact of historical conflicts and Western interventions. Ultimately, the research concludes by recognizing the intertwined nature of trauma, history, and identity within physical and metaphorical spaces. It acknowledges the evolution of characters’ identities like Anil Tissera, who navigate their personal traumas and their nation's scars, seeking a path forward while acknowledging the weight of history. In summary, the manuscript contributes to a deeper understanding of how "Anil's Ghost" navigates the complexities of trauma, identity, and history, shedding light on the relationships between individuals, society, and historical narratives in postcolonial contexts.

Fundamental Characteristics of the Product-Operated Metric Spaces

In the field of metric fixed point theory, there are several generalized or modified types of metric space. One such type is called multiplicative metric space. It was initially introduced as a modified version of the metric space, but was later found to be equivalent to the metric space. However, it allows the researchers to view the concept of metric space from a different perspective. Consequently, the idea of product-operated metric space is introduced in this article, which is obtained by removing the slackness of the multiplicative metric space. This article also presents some fundamental characteristics of the product-operated metric space and investigates the existence of fixed points for self-maps in product-operated metric spaces.

On the completed hull of non-degenerate inner product spaces

Motivated by applications to general QFT, the completed hulls of non-degenerate inner product spaces E, (\,{\cdot}\,,{\cdot}\,) are considered. In order to decide whether or not \smash{\tilde{E}} endowed with the continuously extended inner product (\,{\cdot}\,,{\cdot}\,)^{\sim} is non-degenerate, the concept of c-linked l.c. topologies \tau is introduced, and it is shown that \tilde{E}, (\,{\cdot}\,,{\cdot}\,)^{\sim} is non-degenerate if and only if \tau is c-linked to some minimal majorant. Further, the concepts of quasi-decomposable inner product spaces and quasi-decomposition norms are introduced, and it is shown that \tilde{E}, (\,{\cdot}\,,{\cdot}\,)^{\sim} is a Krein space.

Dynamics of American Political Discourse of the 20th – Early 21st Centuries

The article addresses dynamics of conceptual space and communicative organization of the American political discourse in the 20 th – early 21 st centuries. The research objective is to identify transformations in the content of universal and nationally-marked concepts, as well as verbal modification of communicative strategies and tactics in the American political discourse of the periods under study. The main research methods applied are discourse, conceptual, semantic, and contextual analysis. The sampling corpus incorporates 662 public speeches of American presidents. The speeches under analysis belong to the ritual, orientational, and agonal genres of the political discourse. The main discourse-forming and nationally-marked concepts, features of the communicative structure of the American political discourse are established. The analysis of the metaphorical system as a way of realizing the intention in the American political discourse is carried out. The main types of conceptual metaphor, representing the discourse-forming concepts of the American political discourse are considered. The American political discourse conceptual space is more prone to transformations than its communicative structure in the studied timeframe. The nationally-marked concepts tend to be more dynamic than the universal discourse-forming concepts. The conceptual dynamism of the nationally-marked concepts manifests itself in the prevalence of the dominant features and the lacunarity at different stages of the American linguo-cultural community existence. The nationally-marked concepts components related to the historical and socio-cultural aspects of the speaking community life are brought into the open in the speeches of American presidents as transmitters of the national cultural values and role-status configurations in the political discourse of the 20 th – early 21 st centuries.

The journey within: mental navigation as a novel framework for understanding psychotherapeutic transformation

BackgroundDespite the demonstrated efficacy of psychotherapy, the precise mechanisms that drive therapeutic transformations have posed a challenge and still remain unresolved. Here, we suggest a potential solution to this problem by introducing a framework based on the concept of mental navigation. It refers to our ability to navigate our cognitive space of thoughts, ideas, concepts, and memories, similar to how we navigate physical space. We start by analyzing the neural, cognitive, and experiential constituents intrinsic to mental navigation. Subsequently, we posit that the metaphoric spatial language we employ to articulate introspective experiences (e.g., “unexplored territory” or “going in circles”) serves as a robust marker of mental navigation.MethodsUsing large text corpora, we compared the utilization of spatial language between transcripts of psychotherapy sessions (≈ 12 M. words), casual everyday conversations (≈ 12 M. words), and fictional dialogues in movies (≈ 14 M. words). We also examined 110 psychotherapy transcripts qualitatively to discern patterns and dynamics associated with mental navigation.ResultsWe found a notable increase in the utilization of spatial metaphors during psychotherapy compared to casual everyday dialogues (U = 192.0, p = .001, d = 0.549) and fictional conversations (U = 211, p < .001, d = 0.792). In turn, analyzing the usage of non-spatial metaphors, we did not find significant differences between the three datasets (H = 0.682, p = 0.710). The qualitative analysis highlighted specific examples of mental navigation at play.ConclusionMental navigation might underlie the psychotherapy process and serve as a robust framework for understanding the transformative changes it brings about.

«Отрытый университет»: концептуализация и схематизация Университета 3.0 из перспективы системно-мыследеятельностного подхода (часть 1)

The point is that after the destruction of the classical university, the essentially ‘closed’ ‘University of Excellence’ of B. Ridings took its place almost everywhere. The question is, what should replace it? Our task is to grasp schematically and conceptually the essence of University 3.0 as a real, in our opinion, alternative to the “closed” University of Excellence. To do this, we will rely on a system-my-activity (SMD) approach. Our leading hypothesis is that University 3.0 cannot be understood exclusively as an ‘Entrepreneurial University’ by B. Clark, where an environment has been created for the introduction of scientific innovations into life, but at the same time the idea of ‘autonomy of thinking’ as inherently non-utilitarian, the idea of Culture as the basis for nurturing the Personality of a person who, thanks to this should be ‘raised to the level of his time’ (Ortega-y-Gasset). It is Culture at the university that should become a meeting place for Science and Technology, Research and Business, and the university itself should become a means of cultural transformation (A. Auzan). And the questions are, what exactly does that mean? How exactly to achieve this? In this paper, we have tried to outline a general conceptual space for answering these questions, using a set of concepts and schemes of the SMD methodology.

Concept of introverted space: is multidimensional, extroverted space an illusion?

Abstract The quantum-phase-field concept of matter is revisited with special emphasis on the introverted view of space. Extroverted space surrounds physical objects, while introverted space lies in between physical objects. Space between objects leads to a network structure of matter: a network in which one-dimensional spaces connect individual particles.

Children’s and young people’s cognizance of physical-symbolic reality: The production and acquisition of spatial knowledge

In this article, we address the central topic of the call for papers, childhood educates space, from the perspective of children’s and young people’s spatial knowledge. We argue that both childhood and youth educate as much as are educated by space. To shed light on this dynamic and complex interaction, we focus on the arenas and agencies at play within the production and acquisition of spatial knowledge. The term arena refers to the spatial conditions that delineate an area of activity related to the production and acquisition of spatial knowledge, and agency denotes the crucial means, agents, and tools that are instrumental in and buttress such area of activity. To render operative the analysis, we draw on two driving themes: (i) the gradual development of a comprehensive conception of space and (ii) its accompanying (and traversing) learning processes. Moreover, to substantiate the assertion that education between childhood and youth and space is mutually constitutive, we present a selection of findings from a qualitative meta-analysis conducted to reconstruct the evolution of young people’s spatial knowledge from the 1970s onwards. All in all, we claim that the process of production and acquisition of spatial knowledge forms the basis of, on the one hand, the keenness and depth of the perception that children and young people have of the physical world and, on the other, the ways they subjectively and symbolically characterize it.
