The Relevance of Integrated Reporting in Investment Decision Making: A Proposed Framework
Authors: Baser Abdul Alim , Saleh Zakiah , Abdullah Mazni
Published: December 2022

Research aim: Although Integrated Reporting (IR) has been widely adopted worldwide, literature on its usefulness in stock investment decision making is still scant and inconclusive. As such, this paper aims to articulate a conceptual framework to catechize the nexus between IR information, and stock investment decision making. Design/ Methodology/ Approach: The extant literature on IR is critically reviewed to identify gaps in knowledge, and finally to propose a framework that can link the IR and investment decision making. Research finding: This paper argues that IR information disclosed through six types of capital information (Financial, Human, Intellectual, Manufactured, Natural, and Social and Relational) can impact stock investment decision making both directly and indirectly. The indirect or mediation effect is performed by the reporting engendered firm’s reputation as perceived by the investors. Theoretical contribution/ Originality: Bearing stockholders’ information needs, this paper broadens the demand-side IR literature by showing an otherwise overlooked interlinkage between IR information, and investment decision making. Practitioner/ Policy implication: This paper offers new insights to investors, regulators, and researchers who had been arguing and searching for the usefulness of IR in the capital market. Research limitation: Since IR is a growing field of research, future research might include different behavioural biases or personal values in the proposed investment decision making framework. Keywords: Integrated Reporting (IR), Investment decision, Corporate reputation, Corporate reporting.
The digital ecosystem risk in digital banking: A case study
Authors: Firdaus Fiqhifauzan , Tobing Agustinus Nicholas
Published: December 2022

Rapid technological development encourages disruptive innovation that transforms the concept of the value chain into a digital ecosystem. Companies can leverage the resources of other companies as part of their value chain, without having to own them. It can generate greater risk due to external factors that cannot be controlled directly. Digital Bank Z is a digital bank with a large business ecosystem transforming from Book Bank I. They need to address these potential risks through good risk management while digital banking expansion in Indonesia is increasing rapidly. This case study aims to obtain an evaluation of how the digital transformation and risk management held by Digital Bank Z as well as to produce the conceptual framework for digital ecosystem risks. This qualitative research conducted semi-structured interviews as triangulation with informants from Digital Bank Z and Financial Services Authority or Otoritas Jasa Keuangan (OJK). Digital transformation produces competitive advantages for Digital Bank Z through higher interest rates, but the regulator cited, “digital bank is not a disruptor or competitor”. Recently, risk management is more focusing on operational risk due to no specific regulation of digital banks yet. As recommendations, the conceptual framework provides three stages to identify the risk of collaboration and the digital ecosystem.
“FREQUENCY OF FATAL AND RECURRENT ANAPHYLAXIS DUE TO COW’S MILK: A SYSTEMATIC REVIEW AND META-ANALYSIS OF OBSERVATIONAL STUDIES”.
Authors: Pérez-Codesido Sabela , Grifol-Clar Eulalia , Petrone Marianela Brandoni , Malumbres Marta Goyanes , Garban Patricia Andrade , A Miguel Tejedor-Alonso
Published: December 2022

Background: Cow’s milk allergy can result in anaphylactic reactions. The
estimated prevalence of cow’s milk allergy in developed countries ranges
from 0.5% to 3% at age 1 year. Objective: Our objective was to perform
a systematic review and, if possible, a meta-analysis to assess the
frequency of fatal and recurrent anaphylaxis induced by cow’s milk.
Methods: We searched PubMed/MEDLINE, EMBASE, and the Web of Science for
studies that had assessed fatal and recurrent anaphylaxis induced by
cow’s milk for the population of a country or at least an administrative
region. Our review included cohort, cross-sectional, and registry
studies that had assessed the incidence or prevalence of recurrent
anaphylaxis or the incidence of fatal anaphylaxis due to cow’s milk.
Results: The pooled prevalence of recurrence (PR) for at least an
episode of anaphylaxis was 26.98% (3.41-155.19). Teymourpour et al
(Iran) reported the highest PR (53.10%); the 2 studies with the lowest
PR were from France (5.16 and 0.42 respectively) (p<0.01).
Nine studies on fatal anaphylaxis were selected (41 deaths) and found to
be highly heterogeneous (I =75.91%). Levy et al and
Bassagio et al reported the highest incidence rate (IR 0.15 and 0.6
deaths per million persons-year). Conclusion: The PR of anaphylaxis was
approximately one quarter of patients with anaphylaxis due to cow’s
milk, while deaths from anaphylaxis caused by cow’s milk were very rare,
although some studies report rates as high as 15 times the lowest IR.
Elexacaftor/tezacaftor/ivacaftor Treatment Reduces Airway Inflammation in Cystic Fibrosis
Authors: Vuyst Richard C. De , Bennard Erin , Kam Charissa , McKinzie Cameron , Esther Charles
Published: December 2022

ETI treatment reduces inflammatory markers and positive bacterial
cultures on BAL in PwCF. These findings suggest that ETI has a greater
impact on chronic infection and inflammation than ivacaftor alone.
However, airway inflammation persists in a fraction of treated
individuals, indicating an ongoing need to optimize other treatments in
a subset of patients.
Improving the Representation of Raindrop Size Distributions Using the In-situ Microphysics Observations Collected in Hurricanes
Authors: Leighton Hua , Zhang Xuejin , Black Robert A. , Marks Frank
Published: December 2022

Raindrop Size Distributions (RSDs) samples from 17 flight missions
though 6 hurricanes collected by Precipitation Imaging Probe (PIP)
during National Oceanic and Atmospheric Administration’s hurricane field
program in 2020 are used to study gamma fits of the RSDs in hurricanes.
The method of moment (MM) is adopted for solving for the three
parameters in gamma distribution. The results show that the usage of
lower (higher) moments produces large biases for integral rain variables
(IRV) of higher (lower) moments. These biases can be alleviated by
extracting the best fits from five groups that use increasing higher
orders of moments for MM. An intercept (N0)— slope (λ) relation
identified from the fitted gamma distributions captures 92% of the
variance of the data, where the majority of remaining 8% can be further
captured by including the impact of liquid water content (LWC), as shown
in the results from a random forest regression model.
Quantifying DNAPL source zone longevity with upscaled modeling: practical insights from flow-cell experiments and uncertainty analyses
Authors: Estrada Andres Eduardo Prieto , Widdowson Mark , Stewart Lloyd
Published: December 2022

Estimating dissipation timeframes and contaminant mass discharge rates
of dense non-aqueous phase liquids (DNAPLs) source zones is of key
interest for environmental-management support. Upscaled mathematical
modeling of DNAPL dissolution provides a practical approach for
assimilating site characterization and downgradient monitoring data to
constrain future system behavior. Yet significant uncertainties on
predictions of source zone dissipation rates may arise from inadequate
or inaccurate conceptual assumptions in parameterization designs. These
implications were investigated through upscaled modeling, sensitivity,
and uncertainty analyses of high-resolution flow-cell experiments.
Sensitivity results emphasized the role of local groundwater velocity
and source dimensions in mass transfer scaling by strongly influencing
error with respect to DNAPL persistence and dissolution rates. Linear
uncertainty analyses, facilitated by PEST ancillary software,
demonstrated the worth of monitoring profiles for constraining DNAPL
saturations and dispersive mass transfer rates, responsible for source
zone longevity. Nonlinear analyses performed with the iterative ensemble
smoother PESTPP-iES, facilitated the quantification of unbiased source
dissipation uncertainties from DNAPL delineation data. Conversely,
monitoring data assimilation without consideration of flow-field
heterogeneity and saturation distribution along the flow path biased
model predictions. Our analyses provided practical recommendations on
upscaled model design to assimilate available site data and support
remedial-decision making.
Storage, transport, and fate of perfluoroalkyl acids (PFAAs) in a wastewater re-use and groundwater recharge system
Authors: Jahn Kalle , Saffer Demian M , Freeman Katherine H , Lincoln Sara
Published: December 2022

Perfluoroalkyl acids (PFAAs), a group of synthetic compounds associated
with adverse human health impacts, are commonly found in effluent
discharged from wastewater treatment facilities. When that effluent is
used for irrigation, the fate of PFAAs depends strongly on vadose zone
solute retention properties and loading history. The relative importance
of PFAA retention factors under natural conditions remains uncertain,
and the historical record of effluent PFAA concentrations is limited.
Using soil cores collected from the Penn State Living Filter (irrigated
with treated wastewater effluent for nearly 60 years), we evaluated PFAA
transport under near-natural conditions, and estimated historical PFAA
concentrations in the irrigated effluent. Total perfluorooctanesulfonic
acid (PFOS) and perfluorooctanoic acid (PFOA) masses stored in soils in
2014 were more than 450 times greater than the masses applied during the
2020 effluent irrigation. Equilibrium piston-flow transport models
reproduced the observed PFOS and PFOA profiles, allowing us to estimate
historical effluent PFOS and PFOA concentrations: 70-170 ng L-1 and
1000-1300 ng L-1, respectively. Estimated concentrations were comparable
to concentrations measured in other wastewater effluents in the 1990s
and 2000s, indicating that when interpreted with transport modeling,
wastewater-irrigated soils function as integrated records of historical
PFAA loading. Simulated PFOS breakthrough to groundwater occurred 50
years after the start of wastewater irrigation, while simulated PFOA
breakthrough occurred after only 10 years of irrigation. Thus, while
wastewater irrigation of soils facilitates retention and reduces
effluent PFAA loading to surface waters, the resulting increased PFAA
storage in soils potentially creates long-term sources of PFAAs to
groundwater.
New estimates of the pan-Arctic sea ice--atmosphere neutral drag coefficients from ICESat-2 elevation data
Authors: Mchedlishvili Alexander , Spreen Gunnar , Lüpkes Christof , Petty Alek Aaron , Tsamados Michel
Published: December 2022

The effect that sea ice topography has on the momentum transfer between
ice and atmosphere is not fully quantified due to the vast extent of the
Arctic and limitations of current measurement techniques. Here we
present a method to estimate pan-Arctic momentum transfer via a
parameterization which links sea ice-atmosphere form drag coefficients
with surface feature height and spacing. We measure these sea ice
surface feature parameters using the Cloud and land Elevation
Satellite-2 (ICESat-2) which, though it cannot resolve as well airborne
surveys, has a higher along-track spatial resolution than other
contemporary altimeter satellites. As some narrow obstacles are
effectively smoothed out by the ICESat-2 ATL07 spatial resolution, we
use near-coincident high-resolution Airborne Topographic Mapper (ATM)
elevation data from NASA’s Operation IceBridge (OIB) mission to scale up
the regional ICESat-2 drag estimates. By also incorporating drag due to
open water, floe edges and sea ice skin drag, we produced a time series
of average total pan-Arctic neutral atmospheric drag coefficient
estimates from October 2018 to May 2022. Here we have observed its
temporal evolution to be unique and not directly tied to sea ice extent.
By also mapping 3-month aggregates for the years 2019, 2020 and 2021 for
better regional analysis, we found the thick multiyear ice area directly
north of the Canadian Archipelago and Greenland to be consistently above
2.0 · 10⁻³ with rough ice ~ 1.5 · 10⁻³ typically filling
the full multiyear ice portion of the Arctic each Spring.
Etiology, Epidemiology, and Disparities in the Burden of Diabetic Foot Ulcers
Authors: McDermott Katherine , Fang Michael , Boulton Andrew J.M. , Selvin Elizabeth , Hicks Caitlin W.
Published: December 2022

Diabetic foot ulcers (DFU) are a major source of preventable morbidity in adults with diabetes. Consequences of foot ulcers include decline in functional status, infection, hospitalization, lower-extremity amputation, and death. The lifetime risk of foot ulcer is 19% to 34%, and this number is rising with increased longevity and medical complexity of people with diabetes. Morbidity following incident ulceration is high, with recurrence rates of 65% at 3–5 years, lifetime lower-extremity amputation incidence of 20%, and 5-year mortality of 50–70%. New data suggest overall amputation incidence has increased by as much as 50% in some regions over the past several years after a long period of decline, especially in young and racial and ethnic minority populations. DFU are a common and highly morbid complication of diabetes. The pathway to ulceration, involving loss of sensation, ischemia, and minor trauma, is well established. Amputation and mortality after DFU represent late-stage complications and are strongly linked to poor diabetes management. Current efforts to improve care of patients with DFU have not resulted in consistently lower amputation rates, with evidence of widening disparities and implications for equity in diabetes care. Prevention and early detection of DFU through guideline-directed multidisciplinary care is critical to decrease the morbidity and disparities associated with DFU. This review describes the epidemiology, presentation, and sequelae of DFU, summarizes current evidence-based recommendations for screening and prevention, and highlights disparities in care and outcomes.

The funeral rite of the Mierzanowice Culture in the Vistula and San river basins – graves from Rozbórz, Przeworsk district
Authors: Jarosz Paweł , Mazurek Mirosław , Szczepanek Anita
Published: December 2022

The article describes a small cemetery of the Mierzanowice culture discovered at site 42 in Rozbórz, Przeworsk district, Podkarpackie Voivodship. The necropolis analysed is an example of the diversity of funeral rituals in the area between the Vistula and San rivers in the early Bronze Age. The analysis of the graves’ inventories enabled them to be connected with at least two phases of the cemetery’s utilisation. They can be synchronized with the early (features 668, 1891, 1978, 3141) and classical or late (1834, 2003, 2005) phases of the Mierzanowice culture. The strontium isotopes analyses performed on two individuals indicate that they spent their childhood in the area of the Rzeszów Foothills.

Authors: Käfer Schünke Lídia , Mosmann Clarisse Pereira
Published: December 2022

O objetivo deste estudo foi realizar uma revisão integrativa da literatura sobre a Socialização Financeira Familiar (SFF) sob a ótica da psicologia e das relações familiares. Para compreender de que forma a SFF é definida e avaliada, a revisão seguiu as recomendações do método PRISMA. Foi feita busca por artigos científicos de delineamento quantitativo em inglês, português e espanhol nas bases de dados Scopus, PsychNET, Web of Science, Science Direct, Redalyc, Lilacs, Pepsic, Scielo e Ebscohost, publicados entre os anos de 2010 e 2020. Os resultados mostraram prevalência de estudos realizados nos EUA, com população adulta e sob uma perspectiva individual. Não foram localizados estudos brasileiros. Conclui-se que a SFF está associada a desfechos importantes na vida adulta, porém ainda há carência instrumental para mensuração do construto, bem como lacunas importantes na compreensão e avaliação de aspectos que compõem a dimensão implícita da SFF.
Violência sexual e saúde mental de universitários
Authors: Basso Mariana Silva , Fontana Jordana , Laurenti Carolina
Published: December 2022

A presença da violência sexual nas universidades tem afetado diferentes esferas da vida de estudantes, inclusive a saúde mental. O artigo teve como objetivo investigar e categorizar os efeitos da violência sexual sobre a saúde mental de alunos/as, bem como identificar possíveis estratégias para lidar com o problema. Foi realizada uma sistematização da literatura brasileira dos últimos dez anos. Identificou-se que grande parte dos textos define a violência como um fenômeno sociocultural, e alguns explicam a violência a partir de definições jurídicas. Além disso, constatou-se que a violência sexual produz efeitos prejudiciais de ordem psicológica, física, acadêmica e interpessoal. Sobre as ações de enfrentamento, foi verificado que a maioria das intervenções mencionadas é remediativa. Por já estar instaladas e apresentar efeitos prejudiciais aos estudantes, as estratégias remediativas são necessárias para lidar com os problemas gerados na saúde mental das vítimas. No entanto, como a violência sexual foi considerada majoritariamente um fenômeno de natureza sociocultural, intervenções preventivas também são requeridas para que os determinantes responsáveis pela violência sexual sejam modificados.

Published: December 2022

Enquanto ciência, a Análise do Comportamento tem tecnologia para estudar práticas culturais relacionadas a questões raciais. O objetivo deste estudo foi aplicar uma dessas tecnologias e avaliar os efeitos produzidos por um procedimento de redução de viés racial negativo em relação a pessoas pretas. Foram selecionados 17 participantes, pretos e brancos, que preencheram um questionário de autodeclaração e foram avaliados pelo Implicit Relational Assessment Procedure (IRAP) para definição de linha de base. Por meio de um procedimento de matching-to-sample (MTS), foram treinadas três relações entre estímulos: (a) polegares/figuras abstratas; (b) figuras abstratas/pessoas pretas e figuras abstratas; e (c) relações anteriores simultâneas. Ao término de cada treino, foram realizados testes de simetria, transitividade e equivalência. Utilizou-se novamente o IRAP, para verificar mudanças após o treino. Os resultados indicaram que as respostas dos participantes na linha de base não mostraram viés negativo para pessoas pretas mas, após o treino, houve mudança significativa para participantes brancos. Recomenda-se que pesquisas futuras testem as características do experimentador e outras formas de detecção de viés racial implícito.

Published: December 2022

The article shows the history of the formation of the architecture of Lviv clubs from the beginning of their formation to the present day. Today, there is a trend where iconic historical objects, which often have lost their original function, attract the interest of potential investors. In order not to lose valuable objects of the city’s cultural heritage, a policy of integrating the monument into a new functional context is being pursued. Cultural and educational functions prevail among the most popular solutions: media libraries, co-working spaces, social hubs, art and cultural centers. Their main goal is to revitalize cultural communication and public life in the city. Thanks to modern materials and technologies, architects and designers have the opportunity to create flexible, universal spaces that allows quickly respond to changes in user demand and hold a wide range of events. Innovative approaches in the construction process make it possible to preserve iconic objects and bring the architectural environment of the city into European and world contexts. Modern trends in the development of society indicate that there is an acute need for buildings and spaces for the cultural activities of numerous societies and organizations. Recently, as a result of the diversity of urban life, new forms of public communication have appeared, and therefore, new types of buildings in which such communication takes place. The social conditions of each socio-economic formation leave their mark on the type of building, give it a new social meaning and structure. Therefore, in order to predict the development of multifunctional cultural and educational objects today, to determine their optimal functional structure and volume-spatial solution of the auditorium, capable to exist for different types of events, it is necessary to know and use the architectural experience of past times, when cultural and educational buildings and clubs are becoming the most popular, both on our territory and in the world.

The article is devoted to the first stage of the development of reconstruction project of a historic residential building development – study of the initial data (inventory plans and technical condition of the building), as well as regulatory requirements for the reconstruction of such buildings. The inspection of the technical condition of the residential building is carried out in order to establish the degree of physical wear and tear, determine the possibility of supporting structures to take additional loads and, if necessary, develop measures to strengthen these structures, strengthen the foundation soils and strengthen the foundations, as well as for further monitoring. For further work, it is necessary to study the regulatory requirements for the reconstruction of residential buildings, because the regulatory requirements and restrictions imposed on the reconstruction project are also urban planning, architectural, and constructive and technical in nature. Planning requirements set a list of tasks necessary to create modern living conditions. In general, the project of reconstruction of a residential building involves phased work, which includes: collection of initial data for design (determination of its technical condition, analysis of inventory plans with the existing planning solution, study of design and reconstruction norms), pre-project research of the object (visual inspection of the house and of the adjacent territory, collection of analogues of the reconstruction of residential buildings, photo fixation, dimensions of the residential building, analysis of the structural scheme of the building, load-bearing elements of structures, etc.), stages of sketch design, where the main concepts for reconstruction are developed. The final stage is the development of the reconstruction project, including interiors. The first stage of work is necessary, and a high-quality collection of design materials is the key to the professional reconstruction project creating that will comply with existing norms and rules for the reconstruction and overhaul of historic residential buildings.
UKRAINIAN URBAN TRADITIONS: RELEVANCE IN THE CONDITIONS OF MODERN CHALLENGES
Authors:   Department of Design and Fundamentals of Archicekture, National University “Lviv Polytechnic”, Dyda Iryna
Published: December 2022

The article considers the importance of preserving the architectural environment's national identity in terms of its defense’s effectiveness in modern military operations. A brief overview of the traditional urban characteristics of Ukrainian cities, which in the past ensured their effective defense, was made: the way the buildings are located in the landscape, the planning structure, the height of the buildings, and the density of their location on the territory. The local landscape was actively involved in the architectural organization of the environment, which ultimately determined the unique plan structure for each city and the individual routing of the street network. If necessary, elements of the local landscape were supplemented with artificial systems and used for defense. A significant perimeter of cities with a predominance of traditional manor buildings created difficulties for the organization of the enemy encirclement. Internal fortifications around individual structural elements of the city contributed to long-term defense. To protect large areas, a system of tree-earth ramparts was artificially created. In the past, these measures helped to defend Ukrainian cities effectively. The events of the Russian-Ukrainian war, among other things, revealed that modern weapons, with all their capabilities, could not always overcome landscape obstacles, in particular, ancient defensive walls and swampy areas north of Kyiv; cities that preserved the traditional character of the architectural environment defended more effectively; flat regions of cities, compared to those located on rugged terrain, found themselves in a more threatening situation, etc. All these facts will obviously be subject to detailed analysis in the future. Still, it is already possible to conclude that the preservation of traditional identity in the conditions of a modern architectural environment is essential not only for the self-identification of residents or for the formation of the attractiveness of urban space but also for practical reasons of organizing the effective defense. After all, in the process of long-term formation of the architectural space’s traditional features, the defensive potential of the local landscape many times passed a practical test of its effectiveness by military operations in different historical periods.

The article examines the issue of the influence of the European cohesion policy on approaches to the urban environment and assessing its quality. A number of parameters that determine various aspects of urban space transformation in the context of cohesion policy are analyzed. An assessment of the already existing experience of interpreting public areas is given, both from the point of view of functional efficiency and from the point of view of their aesthetic value. Some directions of the cohesion strategy which influence changes in the value perceptions of the urban space are outlined. The purpose of the article is to determine the likely impact of the European cohesion strategy on the transformation of ideas about the aesthetics of the urban environment. Three directions related to the impact of cohesion policy on the transformation of ideas about the urban environment aesthetics are outlined. They can be defined by: anti-segregation, joint action and topo-solidarity. The first of them is related to a positive reassessment of various forms of openness and interaction. Spaces of common presence, previously separated groups, become a key factor in the value determination of the urban fabric. Elements of virtual and augmented reality, as well as temporary and portable structures, media facades, etc., can be involved in their creation. Traditional means of spatial planning can be perceived as an undesirable rudiment of the urban environment. The second actualizes the concept of aesthetics as maximum variety in a minimum area, primarily pedestrian accessibility. Therefore, homogeneous “ensembles” characteristic of the 20th century are losing their value. The third is related to the creation of city-wide symbols that would reflect the nature of a new type of city-wide solidarity. They have an inclusive nature for positive perception by representatives of the entire multifaceted urban community. It was determined that the change of ideas about the aesthetics of the city under the influence of the cohesion strategy should be considered in conjunction with other phenomena of the transition from the industrial to the information society. The ensemble and rhythmicity of the general masses, the sectoral distribution of territories are gradually giving way to mosaicism and diversity as compositional and functional components. Expanding the category of choice within the pedestrian accessibility zone, freeing the space from barriers and exclusions of various types will be combined with the desire to create universal images – symbols of a new common for all residents of the city, regardless of ethno-confessional and social background.

The problem of research and preservation of architectural heritage is more relevant than ever in Ukraine today. This problem is exacerbated under the influence of modern unstable socio-political processes and possible risks associated with the threat of military aggression from the Russian Federation. Therefore, the historical site of the city of Lviv, the oldest part of which is included in the UNESCO world heritage, needs increased attention and security measures from the authorities, the public and the scientific community. Door and window fillings need special protection, as the materials they are made of, namely wood, metal and glass, are short-lived, which emphasizes the relevance of this research. The Secession period in the art and architecture of Lviv was studied by many scientists, architects and art critics, among whom Yuriy Biryulyov is considered the main researcher in this topic. The purpose of the study is to determine the stylistic features of the solution of the entrance wooden doors in residential buildings built in the period between the end of the 19th and the beginning of the 20th centuries. in Lviv. The study of the stylistic features of the gates was carried out using the methods of compositional analysis (Idak, 2011), which included, in particular, the analysis of the compositional scheme of the doors (grid of axes: first, second and third order), analysis of the placement and shape of light openings (slit openings), analysis of placement, the configuration and nature of the decorative elements that decorate the door, as well as the analysis of the ratio of the proportions of the main elements of the door to the human scale. After that, the study conducted a comparative analysis of the selected doors, on the basis of which common and distinctive characteristics were determined. Based on this, as well as based on the works of researchers of Lviv architecture, the characteristic features of the Secession style were formulated, which were used by craftsmen on Lviv gates made of wood in the Kin period. 19-beginning 20th century.

TRANSFORMATION OF IDEAS ABOUT ARCHITECTURAL FORM IN THE CONTEXT OF METAVERSE ENVIRONMENT DEVELOPMENT

Published: December 2022

The article examines some problems of ideas transformation on architectural form in the conditions of metaverse space. Some factors that, in this regard, affect the change of design priorities is considered. The connection of the emerging new architectural language with the worldview of deconstructivism and postmodernism is traced. The purpose of the article is to trace the transformation of ideas about architectural form in the context of the development of the metaverse space. On the basis of the analysis of projects created by well-known architectural firms for the metaverse environment, two content types of data related to form-creation were selected; they can be conventionally called perceptual and evolutional. Perceptual changes are understood as changes in morphological characteristics that are associated with the disappearance of climatic and gravitational conditions limitations that determined the key parameters of architecture in the real environment. Evolutional type refers to the connection of metaversal morphology with the historical ontology of architectural form in general. Within the framework of the perceptual type of data, the following form regularities are highlighted: a) significant inertia of traditional gravitational statics; b) experiments with the absence of fencing and insurance structures; c) experiments with the illumination of space, which can simultaneously exist in different light modes; d)lack of binding of material imitation to its physical properties; e) tendency to unique attractiveness. Within the limits of the evolutional type, premonitions regarding metaversal form in such tendencies as postmodernism and deconstructivism are considered. In the context of the first, such features as the relativization of time and the understanding of space as a set of events oriented to the communicative effect are highlighted. In the context of the second – attention to astatic and agravating masses, individualization of choice and perception of architecture is emphasized not only as a language where the designer is the “speaker” and the user is the interpreter, but as an equal communication of all participants. The hypothesis is expressed that in the future the main feature of the space of metaverses will be the ability to cause a communicative response, that is, to be the subject of discussion and reflection of its inhabitants. Probably, gradually, this feature will constitute the category of value of metaverse architecture – both artistic and economic.
