Os Descaminhos da Dialética Hegeliana entre Lógica e Natureza

The aim of this study is to investigate the relationship between Logic and Nature within the Hegelian system. Our focus lies on the status of the categories of nature: are they merely a redoubling of the equivalent logical categories or is there a substantial difference between them? First, we analyze the secondary literature on the subject and conclude that it falls short of the complexity of the problem. Secondly, we make a detailed comparison between the Philosophy of Nature and the Science of Logic and hypothesize that the natural categories presuppose logic as a standard, that is, a kind of ruler that determines what the ideal development would be; however, as nature fails to faithfully reproduce this standard, its categories deviate considerably from the logical categories.

The Brain's Sensitivity to Real-world Statistical Regularity Does Not Require Full Attention.

Predictive coding accounts of perception state that the brain generates perceptual predictions in the service of processing incoming sensory data. These predictions are hypothesized to be afforded by the brain's ability to internalize useful patterns, that is, statistical regularities, from the environment. We have previously argued that the N300 ERP component serves as an index of the brain's use of representations of (real-world) statistical regularities. However, we do not yet know whether overt attention is necessary in order for this process to engage. We addressed this question by presenting stimuli of either high or low real-world statistical regularity in terms of their representativeness (good/bad exemplars of natural scene categories) to participants who either fully attended the stimuli or were distracted by another task (attended/distracted conditions). Replicating past work, N300 responses were larger to bad than to good scene exemplars, and furthermore, we demonstrate minimal impacts of distraction on N300 effects. Thus, it seems that overtly focused attention is not required to maintain the brain's sensitivity to real-world statistical regularity. Furthermore, in an exploratory analysis, we showed that providing additional, artificial regularities, formed by altering the proportions of good and bad exemplars within blocks, further enhanced the N300 effect in both attended and distracted conditions, shedding light on the relationship between statistical regularities learned in the real world and those learned within the context of an experiment.

Cultural Heritage Sites Risk Assessment and Management Using a Hybridized Technique Based on GIS and SWOT-AHP in the Ancient City of Ibb, Yemen

ABSTRACT The conservation of Cultural Heritage (CH) sites is vital for conserving a nation’s historical, architectural, and socio-cultural identity, especially in areas like Yemen, where such sites are threatened by natural hazards, urban development, and various anthropogenic activities. This study addresses these challenges by introducing a comprehensive risk assessment and management framework, with a focused case study on the ancient city of Ibb – a region with significant CH. The study employs a novel hybridized approach that combines Geographic Information Systems (GIS) with the Strength, Weakness, Opportunity, and Threat (SWOT) – Analytic Hierarchy Process (AHP) to identify thirteen critical factors influencing site suitability. These factors are classified into natural and anthropogenic categories and are systematically analyzed using GIS techniques. Additionally, the study identified and evaluated 16 SWOT factors using structured questionnaire surveys, which inform an integrated SWOT and AHP methodology. The findings revealed that the study area is mainly classified from very high to very low-risk areas, representing very high (37.2%), high (24.3%), moderate (17.7%), low (12.3%), and very low (8.5%), of the total study area, indicating that most of them are in highly hazardous environments, necessitating urgent attention and the implementation of protective measures. This study offers valuable insights and optimization strategies for safeguarding the CH sites of the ancient City of Ibb. It is particularly useful for policymakers, conservationists, and local stakeholders, providing a scalable approach that can be adapted to manage risks at other CH sites facing similar threats, thus making a significant contribution to the field of heritage risk management.

The primacy of experience in language processing: Semantic priming is driven primarily by experiential similarity

The organization of semantic memory, including memory for word meanings, has long been a central question in cognitive science. Although there is general agreement that word meaning representations must make contact with sensory-motor and affective experiences in a non-arbitrary fashion, the nature of this relationship remains controversial. One prominent view proposes that word meanings are represented directly in terms of their experiential content (i.e., sensory-motor and affective representations). Opponents of this view argue that the representation of word meanings reflects primarily taxonomic structure, that is, their relationships to natural categories. In addition, the recent success of language models based on word co-occurrence (i.e., distributional) information in emulating human linguistic behavior has led to proposals that this kind of information may play an important role in the representation of lexical concepts. We used a semantic priming paradigm designed for representational similarity analysis (RSA) to quantitatively assess how well each of these theories explains the representational similarity pattern for a large set of words. Crucially, we used partial correlation RSA to account for intercorrelations between model predictions, which allowed us to assess, for the first time, the unique effect of each model. Semantic priming was driven primarily by experiential similarity between prime and target, with no evidence of an independent effect of distributional or taxonomic similarity. Furthermore, only the experiential models accounted for unique variance in priming after partialling out explicit similarity ratings. These results support experiential accounts of semantic representation and indicate that, despite their good performance at some linguistic tasks, the distributional models evaluated here do not encode the same kind of information used by the human semantic system.

The lived experiences and perceptions of middle-aged adults in Dominica who have survived severe storms-a qualitative exploration.

The Eastern Caribbean island of Dominica has experienced diverse negative effects from the North Atlantic hurricane season, including deadly storms like Hurricane Maria in 2017. Vulnerability is increased by geographic location, small island developing state (SIDS) status, and ecosystem characteristics. A variety of negative health effects including stress and anxiety are caused by powerful storms. The perspectives of middle-aged (the "sandwich generation") survivors in this post-storm milieu are understudied. This phenomenological qualitative study describes the perceptions of middle-aged (35-55 years) Dominicans, purposively recruited with gatekeeper assistance from communities stratified according to four natural hazard vulnerability categories designated by the Climate Resilience Execution Agency for Dominica (CREAD), regarding their lived experiences in the context of severe storms. Data was collected between June and August 2022, using primarily Zoom-based semi-structured, individual interviews (12 of 13), guided by the principles of saturation and maximum variation. Verbatim interview transcripts were thematically analyzed with constant comparison using an ATLAS.ti-supported hybrid deductive-inductive coding frame. Reflexivity and contact summary sheets were used to minimize bias. Ten women and three men from diverse CREAD vulnerability and sociodemographic backgrounds were recruited. Data condensation yielded three organizing themes: (i) "The diverse health effects of severe storms", (ii) "Response to and recovery from severe storms", and (iii) "Preparedness and precaution for severe storms". These themes encapsulated the health impacts of severe storms on Dominicans and elucidated the role of facilitating and barricading resilience factors. Severe storms produced direct and indirect mental, social, and physical health impacts on middle-aged Dominicans, including anxiety and burnout. Participants used faith-based, tangible community-based support, and emotional mechanisms to cope with and demonstrate resilience. Better risk communication and early warning systems would improve population readiness. Persistent dispirited attitudes toward storm preparedness among some participants suggest the need for targeted methods to enhance community involvement in disaster planning, including traditional approaches like "coup-de-main" (self-help).

Conceptualizing patient interactions eliciting empathy, compassion, reflection, and social projection: A model with analysis.

Conceptualizing the next patient interaction is logical, essential, and largely done intuitively with limited literature. The first objective is to elicit student thought experiences to four questions. The secondary objective is to classify responses for respective questions and to review faculty assessments. Forty-two students completed the exercise in the first clinical prosthodontics experience after a simulation course, in the fall of 2023. Four open-ended questions were 1) differentiation from the ideal, 2) desired outcome(s), 3) self-capabilities, and 4) consequences/prognosis. Nine different faculty assessed the exercise. 100% of students responded to all four questions and 83% of responses were judged by faculty to grasp the concept in the question. The authors categorized responses into natural categories for each question. Authors separately assigned responses to categories. The agreement rate was 90%. Little to no overlap in responses was observed among the four questions. The sequence of questions led students to thought experiences from empathy in Question #1, to compassion in Question #2, and to self-reflection in Question #3 to social projection in Question #4. The main objective was met by engaging students in thought-provoking responses to questions the experienced clinician asks of every patient encounter. The exercise elicited different kinds of thought experiences on four topics. The format was succinct with acceptance by students and faculty. The project has progressed from a concept some years ago to a recent pilot to full implementation with the current project. The next steps will be refinement and follow-up in some years. The project follows an emulation model for critical thinking.

Financial performance of mutual and pension funds focused on the natural resources sector

The natural resource sector plays a critical role in advancing sustainable development. However, fossil fuels, precious metals, and mineral extraction require large investments, which mutual and pension funds may assume when allowing fund managers to fulfil their fiduciary duties. This study examines the financial performance of conventional, natural resource, energy, and precious metal-related mutual and pension funds, considering the effects of the COVID-19 pandemic. We adopted a five-factor model with a sample of 42 natural resource funds, 45 energy funds, 45 precious metal funds, and 2172 conventional funds from January 2016 to December 2022. The results indicate that driven by fund managers’ reverse stock-picking skills, the precious metal fund category reaches the lowest mean risk-adjusted return in relation to the energy, natural resources, and conventional fund categories. Additionally, the COVID-19 global health crisis negatively affected the mean risk-adjusted returns on the energy, precious metals, and conventional funding categories. A similar effect is observed in the natural resource pension fund category, while its matching mutual fund category achieves similar financial performance during the non-crisis and crisis periods.

Variation in the 1sg.indef: More than you wanted to know

AbstractThe first person singular indefinite or non-definite of Hungarian verbs that end in -ik shows variation between the regular -k suffix and the -m suffix, used otherwise in the definite. This variation is systematic and subject to metalinguistic awareness. Our study relies on previous quantitative work, a frequency dictionary compiled from the new Hungarian Webcorpus, as well as a forced-choice elicitation experiment to assess the role of word frequency, word length, derivational endings, and across-form similarity in shaping this variation. We find that first person singular indefinite variation is largely defined by natural categories: verbs that look similar will also show a similar preference to -k/-m. This pattern is attested in the webcorpus as well as in participant responses in the elicitation task.

An examination of measures of young children's interest in natural object categories

Developmental research utilizes various different methodologies and measures to study the cognitive development of young children; however, the reliability and validity of such measures have been a critical issue in all areas of research practices. To address this problem, particularly in the area of research on infants' interests, we examined the convergent validity of previously reported measures of children's interests in natural object categories, as indexed by (1) parents' estimation of their child's interest in the categories, (2) extrinsic (overt choices in a task), (3) intrinsic (looking time toward objects), and (4) physiological (pupil dilation) responses to objects of different categories. Additionally, we also examined the discriminant validity of all the aforementioned measures against the well-established and validated measure of parents' estimations of children's vocabulary knowledge. Children completed two tasks: (a) an eye-tracking task, where they were presented with images from a range of defined categories, which collected indices of looking time and pupillary activity; (b) a sticker-choice task, where they were asked to choose between two sticker-images from two different categories belonging to the range of categories assessed in the previous task. Parents completed two questionnaires to estimate (i) their child's interests and (ii) vocabulary knowledge in the categories presented. We first analyzed the discriminant validity between the two parent measures, and found a significant positive association between them. Our successive analyses showed no strong or significant associations between any of our measures, apart from a significant positive association between children's looking time and parents' estimations of children's vocabulary knowledge. From our findings, we conclude that measures of infants' interests thus far may not have sufficient reliability to adequately capture any potential relationship between these measures, or index different components of interest in young children. We suggest next steps for further validation studies in infant research.

Quantifying Bias in Hierarchical Category Systems.

Categorization is ubiquitous in human cognition and society, and shapes how we perceive and understand the world. Because categories reflect the needs and perspectives of their creators, no category system is entirely objective, and inbuilt biases can have harmful social consequences. Here we propose methods for measuring biases in hierarchical systems of categories, a common form of category organization with multiple levels of abstraction. We illustrate these methods by quantifying the extent to which library classification systems are biased in favour of western concepts and male authors. We analyze a large library data set including more than 3 million books organized into thousands of categories, and find that categories related to religion show greater western bias than do categories related to literature or history, and that books written by men are distributed more broadly across library classification systems than are books written by women. We also find that the Dewey Decimal Classification shows a greater level of bias than does the Library of Congress Classification. Although we focus on library classification as a case study, our methods are general, and can be used to measure biases in both natural and institutional category systems across a range of domains.

Tensor Categories for Vertex Operator Superalgebra Extensions

Let V V be a vertex operator algebra with a category C \mathcal {C} of (generalized) modules that has vertex tensor category structure, and thus braided tensor category structure, and let A A be a vertex operator (super)algebra extension of V V . We employ tensor categories to study untwisted (also called local) A A -modules in C \mathcal {C} , using results of Huang-Kirillov-Lepowsky that show that A A is a (super)algebra object in C \mathcal {C} and that generalized A A -modules in C \mathcal {C} correspond exactly to local modules for the corresponding (super)algebra object. Both categories, of local modules for a C \mathcal {C} -algebra and (under suitable conditions) of generalized A A -modules, have natural braided monoidal category structure, given in the first case by Pareigis and Kirillov-Ostrik and in the second case by Huang-Lepowsky-Zhang. Our main result is that the Huang-Kirillov-Lepowsky isomorphism of categories between local (super)algebra modules and extended vertex operator (super)algebra modules is also an isomorphism of braided monoidal (super)categories. Using this result, we show that induction from a suitable subcategory of V V -modules to A A -modules is a vertex tensor functor. Two applications are given: First, we derive Verlinde formulae for regular vertex operator superalgebras and regular 1 2 Z \frac {1}{2}\mathbb {Z} -graded vertex operator algebras by realizing them as (super)algebra objects in the vertex tensor categories of their even and Z \mathbb {Z} -graded components, respectively. Second, we analyze parafermionic cosets C = C o m ( V L , V ) C=\mathrm {Com}(V_L,V) where L L is a positive definite even lattice and V V is regular. If the vertex tensor category of either V V -modules or C C -modules is understood, then our results classify all inequivalent simple modules for the other algebra and determine their fusion rules and modular character transformations. We illustrate both directions with several examples.

The role of natural recovery category in malaria dynamics under saturated treatment.

In the process of malaria transmission, natural recovery individuals are slightly infectious compared with infected individuals. Our concern is whether the infectivity of natural recovery category can be ignored in areas with limited medical resources, so as to reveal the epidemic pattern of malaria with simpler analysis. To achieve this, we incorporate saturated treatment into two-compartment and three-compartment models, and the infectivity of natural recovery category is only reflected in the latter. The non-spatial two-compartment model can admit backward bifurcation. Its spatial version does not possess rich dynamics. Besides, the non-spatial three-compartment model can undergo backward bifurcation, Hopf bifurcation and Bogdanov-Takens bifurcation. For spatial three-compartment model, due to the complexity of characteristic equation, we apply Shengjin's Distinguishing Means to realize stability analysis. Further, the model exhibits Turing instability, Hopf bifurcation and Turing-Hopf bifurcation. This makes the model may admit bistability or even tristability when its basic reproduction number less than one. Biologically, malaria may present a variety of epidemic trends, such as elimination or inhomogeneous distribution in space and periodic fluctuation in time of infectious populations. Notably, parameter regions are given to illustrate substitution effect of two-compartment model for three-compartment model in both scenarios without or with spatial movement. Finally, spatial three-compartment model is used to present malaria transmission in Burundi. The application of efficiency index enables us to determine the most effective method to control the number of cases in different scenarios.

'You Can Resurrect Me, but Only Piecemeal': Embodied Texts and the Heterotopian Regeneration of the Cyborg

This article explores Donna Haraway’s concept of the cyborg through its prosthetic and heterotopian extension in embodied text. With this fractured and ironic ‘cyborg’ figure, Haraway attempted to move feminist theory and politics into a new direction that broke with second-wave feminism’s perpetual reconceptualization of ‘the woman’ as a natural category. However, the text also became the subject of scholarly critique for dissolving the singularities and material contexts of the bodies marginalized by the categories of gender that Haraway’s abstract and utopian metaphor of the cyborg excludes. Unlike these critics’ disposal of the cyborg, this article stays with this monstrous creature and attempts to give her back some embodied singularities, whilst further elaborating Haraway’s concept of ‘cyborg writing’ and close-reading Shelley Jackson’s digital hypertext novel Patchwork Girl (1995). In this hypertext novel, Jackson creates a new myth from the torn-apart body parts of the monstrous female companion of Frankenstein’s monster in Mary Shelley’s original novel. Readers are invited to cooperate in the infinite tearing apart and stitching together of this female monster and, in doing so, form the text as heterotopian; the embodied practices of readers in actual space are, namely, co-constitutive of the text’s multiple and always changing form. The author argues that focusing on the way Patchwork Girl’saesthetics and literal uses of prostheses endlessly move this—and within this—heterotopian regeneration, makes present how Jackson’s hypertext departs from Haraway’s theoretical text and gives way to the acting out of a queerness that cannot imagine its place in utopia. Like Haraway, Jackson emphasizes the fragmentary nature of bodies and subjectivities. But Patchwork Girl’s never-resting hypertext makes these bodies, and their prosthetic extensions betray the theoretical territory of metaphor and abstraction.

Crossmodal associations between naturally occurring tactile and sound textures.

This study investigates the crossmodal associations between naturally occurring sound textures and tactile textures. Previous research has demonstrated the association between low-level sensory features of sound and touch, as well as higher-level, cognitively mediated associations involving language, emotions, and metaphors. However, stimuli like textures, which are found in both modalities have received less attention. In this study, we conducted two experiments: a free association task and a two alternate forced choice task using everyday tactile textures and sound textures selected from natural sound categories. The results revealed consistent crossmodal associations reported by participants between the textures of the two modalities. They tended to associate more sound textures (e.g., wood shavings and sandpaper) with tactile surfaces that were rated as harder, rougher, and intermediate on the sticky-slippery scale. While some participants based the auditory-tactile association on sensory features, others made the associations based on semantic relationships, co-occurrence in nature, and emotional mediation. Interestingly, the statistical features of the sound textures (mean, variance, kurtosis, power, autocorrelation, and correlation) did not show significant correlations with the crossmodal associations, indicating a higher-level association. This study provides insights into auditory-tactile associations by highlighting the role of sensory and emotional (or cognitive) factors in prompting these associations.

Gender Differences in Work-Based Assessment Scores and Narrative Comments After Direct Observation.

While some prior studies of work-based assessment (WBA) numeric ratings have not shown gender differences, they have been unable to account for the true performance of the resident or explore narrative differences by gender. To explore gender differences in WBA ratings as well as narrative comments (when scripted performance was known). Secondary analysis of WBAs obtained from a randomized controlled trial of a longitudinal rater training intervention in 2018-2019. Participating faculty (n = 77) observed standardized resident-patient encounters and subsequently completed rater assessment forms (RAFs). Participating faculty in longitudinal rater training. Gender differences in mean entrustment ratings (4-point scale) were assessed with multivariable regression (adjusted for scripted performance, rater and resident demographics, and the interaction between study arm and time period [pre- versus post-intervention]). Using pre-specified natural language processing categories (masculine, feminine, agentic, and communal words), multivariable linear regression was used to determine associations of word use in the narrative comments with resident gender, race, and skill level, faculty demographics, and interaction between the study arm and the time period (pre- versus post-intervention). Across 1527 RAFs, there were significant differences in entrustment ratings between women and men standardized residents (2.29 versus 2.54, respectively, p < 0.001) after correction for resident skill level. As compared to men, feminine terms were more common for comments of what the resident did poorly among women residents (β 0.45, CI 0.12-0.78, p 0.01). This persisted despite adjusting for the faculty's entrustment ratings. There were no other significant linguistic differences by gender. Contrasting prior studies, we found entrustment rating differences in a simulated WBA which persisted after adjusting for the resident's scripted performance. There were also linguistic differences by gender after adjusting for entrustment ratings, with feminine terms being used more frequently in comments about women in some, but not all narrative comments.

New marker for chronic kidney disease progression and mortality in medical-word virtual space

A new marker reflecting the pathophysiology of chronic kidney disease (CKD) has been desired for its therapy. In this study, we developed a virtual space where data in medical words and those of actual CKD patients were unified by natural language processing and category theory. A virtual space of medical words was constructed from the CKD-related literature (n = 165,271) using Word2Vec, in which 106,612 words composed a network. The network satisfied vector calculations, and retained the meanings of medical words. The data of CKD patients of a cohort study for 3 years (n = 26,433) were transformed into the network as medical-word vectors. We let the relationship between vectors of patient data and the outcome (dialysis or death) be a marker (inner product). Then, the inner product accurately predicted the outcomes: C-statistics of 0.911 (95% CI 0.897, 0.924). Cox proportional hazards models showed that the risk of the outcomes in the high-inner-product group was 21.92 (95% CI 14.77, 32.51) times higher than that in the low-inner-product group. This study showed that CKD patients can be treated as a network of medical words that reflect the pathophysiological condition of CKD and the risks of CKD progression and mortality.

Evaluation of potential trace element contamination and ecological risks of beach sediments, Andaman and Nicobar Archipelago, India

This study emphasized the potential contamination level and ecological risk condition of the beach sediments in the Andaman and Nicobar archipelago. The mean concentration of acid -leachable trace metals (ALTMs) shows the following descending order: North Andaman sector: Pb > Zn > Ni > Co > Cr > Fe > Cu > Mn; Middle Andaman sector: Fe > Ni > Pb > Zn > Cr > Co > Mn > Cu; South Andaman sector: Fe > Ni > Pb > Zn > Cr > Co > Mn > Cu; Rutland Island sector: Ni > Fe > Pb > Zn > Co > Cr > Cu > Mn; Little Andaman sector: Ni > Pb > Zn > Co > Cr > Fe > Cu > Mn; Great Nicobar Island sector: Fe > Ni > Cr > Pb > Zn > Co > Mn > Cu. The enrichment factor shows the metal enrichment trend as follows: Pb > Ni > Cr > Cu > Mn > Zn. ALTM’s results reveal that Fe, Mn, Pb, and Cu are the most notable trace elements in the beach sediments. The geo-accumulation index of metals shows an unpolluted category for all the metals except Pb. The level of sediment contamination indicates the moderate to strong category. The sediment pollution index and ecological risk reveal that the sediment belongs to the natural category with low pollution risk. The concentration of metal in the beaches was less than the comparative studies and sediment quality guidelines (SQGs). Overall assessment studies on sediment accumulated trace metals and potential ecological studies suggest that the beach sediments of the study area were less contaminated and exposed to low risk.

Natural joint effect on mechanical characteristics and fracture evolution of In-Site rocks under uniaxial compression

Understanding the strength features and failure characteristics of in-site rocks with various natural joints is an important fundament for studying the stability of underground engineering. The rock specimens with different joint angles, joint lengths, and joint distribution types were prepared and tested in uniaxial compressive test UCT combined with the acoustic emission AE detection. The natural joint categories of rock specimens were divided into single-joint type, cross-joint type, and mixed-joint type according to the number of joints and the gradual deterioration degree of integrity. The research results showed that the lower integrity could degrade the mechanical properties. The AE parameters as well as three types of energies all exhibited a firstly increasing and then decreasing trend with the increase of dominant joint angle αA. Rock specimens with lower intactness generated AE events with higher intensity and energy, resulting in a higher proportion of energy loss and lower severity of damage. The integrity of the natural jointed rock was verified by fractal dimension. The activity of micro-cracks within natural jointed rocks was characterized by both fractal dimension and AE b-value, and found that their trends were synchronized. A classification criterion that combined clustering techniques, AE parameter features, and genetic algorithms for tensile and shear cracks generated during the rock failure process was proposed. It’s demonstrated that the ratio of shear cracks to the total cracks showed an initial increase followed by a decrease with the increase of αA. Hoek-Brown's empirical formula was improved and the rating scores related to the uniaxial compressive strength Rucs-scores were continuouszed for natural jointed rock.

GEOECOLOGICAL ASSESSMENT OF LAND USE STRUCTURE OF THE PIDGORODNYA TERRITORIAL COMMUNITY

The purpose of the study is to assess the geo-environmental parameters and optimize the land use structure of the Pidgorodnya territorial community. The authors used special methods to determine the anthropogenic load, coefficients of ecological stability and anthropogenic transformation of the territory of the Pidgorodnya territorial community.&#x0D; The Pidgorodnya territorial community is located in the center of Ternopil region and Ternopil district, covering an area of 123.47 km². The community is home to 7418 people. The Pidgorodnya community was established in 2020 and unites 7 rural settlements, on the basis of which 6 starosta districts and a center in the village of Pidhorodne were created. The soil cover of the study area is among the most fertile soils in the region. There are two rivers and 8 ponds within the community.&#x0D; The article analyses and geo-ecologically assesses the land use structure of the Pidgorodnya community. It is established that the structure of land use in the study area is dominated by arable land (71%), forests occupy 7%, built-up land - 4%, pastures - 9%, hayfields - 5%, perennial plantations - 3%, land under water and swamps - 1%. The share of natural lands in the community is 27%, and the level of community conservation is 1.1%. The community has created 5 protected areas: a botanical garden, 2 botanical reserves and 2 botanical natural monuments with a total area of 135.5 hectares.&#x0D; Based on the results of the calculations, the coefficient of anthropogenic transformation of the territory of the Pidgorodnya territorial community was determined, which is 6,16; the coefficient of ecological stability – 0,28; anthropogenic load score is 3,7 and the coefficient of anthropogenic load – 3,7. According to the results obtained, it was found that the territory of the Pidgorodnya territorial community is ecologically unstable with an average degree of landscape transformation, and an average degree of anthropogenic pressure. Based on the calculations and results obtained, we can state the need to optimise the land use structure of the Pidgorodnya territorial community.&#x0D; In order to correct and improve the situation and bring the study area to the normative indicators of environmental stability, a number of optimization measures a number of optimization measures should be taken. The article substantiates the optimisation model of land use of the Pidgorodnya territorial community, which provides for a reduction of arable land by 25%, an increase in forest cover by 17%, and bringing the share of natural lands to the optimal level of 50%. Given the landscape features of the study area, we propose to reduce arable land at the expense of low-productive and eroded lands. Thus, the optimised land use structure of the Pidgorodnya territorial community will include 46% arable land, 24% forests, 25% pastures, hayfields and perennial plantations, 4% built-up land, and 1% land under water and marshes. Implementation of this approach requires changing the designated purpose of individual land plots and organising their landscape-adapted use. The prospect of further research is to determine the areas of land for transferring them from the anthropogenic category to the natural category, with further optimisation.&#x0D; Key words: geoecological assessment, land use, ecological stability, anthropogenic load.

Assessment of Urban Local High-Temperature Disaster Risk and the Spatially Heterogeneous Impacts of Blue-Green Space

Urban high-temperature disasters have gradually emerged as a significant threat to human society. Therefore, it is crucial to assess and identify areas at risk of such disasters and implement urban planning measures aimed at mitigating their impact. Additionally, a multitude of studies have demonstrated the significant cooling effect of urban blue-green spaces (UGBS), which play a pivotal role in urban environments. Incorporating a UBGS layout into planning and evaluation processes has substantial potential for mitigating high-temperature disasters. This paper presents the construction of a set of assessment processes for mitigating urban high-temperature disaster risk using a UBGS structure layout specifically for the main urban area of Harbin, China. We employed GIS and multi-source remote sensing imagery to develop local climate zone (LCZ) maps applicable to the designated study area. The differentiated impact of UBGS factors on high-temperature disaster risk was determined using the multi-scale geographical weighted regression model (MGWR). The results showed the following: (a) There was an overall low risk level, with 19.61% of the high-risk areas concentrated within the second ring road, forming a spatial pattern characterized by “one line, one cluster”. (b) The risk of the building category LCZs was generally higher than that of the natural category LCZs. The risk of the architectural LCZs could be summarized as the risk of low-density LCZs being smaller than that of the high-density LCZs, except LCZ 5. The mean value of the LCZ 2 and LCZ 5 types was the highest. (c) Through indicator screening, AREA_MN, SHAPE_MN, PD, and NP were found to be significant determinants influencing the risk, and the effectiveness and spatial differentiation of these main factors exhibited notable disparities. (d) By comparing different LCZ types, we concluded that the mitigation effect of these factors on risk may be interfered with by building height (BH); NP may be positively interfered with by BH; and PD and SHAPE_MN may be negatively interfered with by BH. The research results provided a new perspective and practical scientific basis for high-temperature disaster risk-mitigation planning based on UBGSs under LCZ classification.
