Youth itineraries, individuation, and reflexivities: approaches to social participation in low-income metropolitan neighborhoods
Authors: Pinheiro Leandro R. , Di Leo Pablo Francisco , Varela Francisco Ramírez
Published: December 2023

Abstract This study analyzes individuation itineraries by considering the forms of participation and reflexivity of young people who live in low-income neighborhoods in three metropolitan areas: Buenos Aires/Argentina, Porto Alegre/Brazil, and Santiago/Chile. For this, this study articulated the results of several empirical studies conducted from 2013 to 2019 with the conceptual tools in Danilo Martuccelli’s sociology of the individual, especially its notions of tests, supports, and social textures. This research first addresses theoretical frameworks to implement its problem and methodological strategies to build and analyze youth’s narratives. Then, it interpreted its data corpus around two central axes: a) low-income territories, actors, and interworlds and b) young people, social participation, and reflexivities. Young people face a plurality of material and symbolic coercions in several low-income territories. However, these territories also create collective spaces in which youths establish personal and group identifications as they discover or generate sports, artistic-political, and educational proposals, which create intergenerational bonds, recover ancestral knowledge, and build referential and reflective landmarks, transforming territorialities into supports and a sign of recognition. Thus, studying youth narratives offers a privileged tool to analyze Latin American low-income agencies and individualities.

Solar energy is a safe and clean source of energy, available on the Earth throughout the year. A photovoltaic/thermal (PV/T) system is a device designed to take solar energy and convert it into electrical/thermal energy. Photovoltaic/ thermal systems can also be useful to produce hot fluid (usually water) along with the generation of electrical energy. In addition, the electric generating performance of PVs increases with heat discharging ability of thermal system, which also prevents overheating in PV systems. Nanofluid is a new generation heat transfer fluid that delivers higher thermal conductivity and heat transfer rate compared to conventional fluids. The thermal conductivity of the nanofluid depends on the size of the nanoparticles, concentration of the nanofluid, and the method of its preparation. In this study, it is aimed to increase the thermal heat transfer of the PV/T system by using hybrid nanofluids, manufactured by adding 0.5% Fe2O3 and Fe3O4 nanoparticles to the water as a working fluid. By using hybrid nanofluids, increase in bidirectional performance along with enhanced cooling is achieved. In the experimental study, more heat was withdrawn from the heated PV panels by utilizing the high thermal conductivity of the hybrid nanofluid, and the best improvement in total efficiency was obtained as 86% for the hybrid nanofluid. With the use of hybrid nanofluids in the cooling circuit, the electrical and thermal efficiency of the PV panel has reached to overall 81% on average basis.
MORE POWERFUL HSIC-BASED INDEPENDENCE TESTS, EXTENSION TO SPACE-FILLING DESIGNS AND FUNCTIONAL DATA
Authors: El Amri Mohamed Reda , Marrel Amandine
Published: December 2023

The Hilbert-Schmidt independence criterion (HSIC) is a dependence measure based on reproducing kernel Hilbert
spaces. This measure can be used for the global sensitivity analysis of numerical simulators whose objective is to identify the most influential inputs on the output(s) of the code. For this purpose, HSIC-based sensitivity measures and
independence tests can be used for the ranking and screening of inputs, respectively. In this framework, this work
proposes several improvements in the use of HSIC to increase their application spectrum and make the associated independence tests more powerful. First, we introduce a new method to perform the tests in a non-asymptotic framework.
This method is much less central-processing-time expensive than the one based on permutation, while remaining as
efficient. Then, the use of HSIC-based independence tests is extended to the case of some space-filling designs, where
the independent and identically distributed condition of the observations is lifted. For this, a new procedure based on
conditional randomization test is used. In addition, we also propose a more powerful test that relies on a well-chosen
parameterization of the HSIC statistics: the kernel bandwidth parameter is optimized instead of the standard choices. Numerical studies are performed to assess the efficiency of these procedures and compare it to existing tests in the literature. Finally, HSIC-based indices for functional outputs are defined: they rely on appropriate and relevant kernels for this type of data. Illustrations are provided on temporal outputs of an analytical function and a compartmental epidemiological model.

Authors: Majeed Ghufran M. , Adil Ban. H , Al-Wasiti Estabraq  AR.
Published: December 2023

This study employed a physical method to produce selenium nanoparticles (SeNPs) using selenium nitrate and cold plasma under normal atmospheric pressure. The experiment involved three distinct exposure times (10, 12, and 14 min) for synthesizing SeNPs, followed by an exploration of loading selenium with tamoxifen citrate (TAM) at a 14-min exposure time and various concentration ratios (1:9, 2:8, 3:7, 4:6, and 5:5). Ultraviolet-visible (UV-VIS) spectroscopy was used to characterize the SeNPs and SeNP-tamoxifen (TAM), with observed absorbance increasing with material concentration. Further analysis methods, including XRD and FE-SEM, were employed to investigate nanoparticle properties. Successful integration of SeNPs into tamoxifen citrate led to the formation of SeNPs-TAM, exhibiting a spherical shape and desirable nanoscale dimensions. Notably, SeNPs-TAM demonstrated potent anti-proliferation efficacy against diverse cancer cells, including REF and AMJ 13 cell lines, surpassing both SeNPs and free tamoxifen citrate in their individual forms. The findings emphasized the exceptional selectivity and apoptosis-inducing anti-cancer activity of the SeNPs-TAM combination.

The perception of vowelless words in Tashlhiyt
Authors: Zellou Georgia , Lahrouchi Mohamed , Bensoukas Karim
Published: December 2023

This study examines the perceptual mechanisms involved in the processing of words without vowels, a lexical form that is common in Tashlhiyt but highly dispreferred cross-linguistically. In Experiment 1, native Tashlhiyt and non-native (English-speaking) listeners completed a paired discrimination task where the middle segment of the different-pair was either a vowel (e.g., fan vs. fin), consonant (e.g., ʁbr vs. ʁdr), or vowelless vs. voweled contrast (e.g., tlf vs. tuf). Experiment 2 was a word-likeness ratings task of tri-segmental nonwords constructed to vary in the sonority of the middle segment. We find that vowelless words containing different types of sonority profiles were generally highly discriminable by both native and non-native listeners. This can be explained by the phonetic and acoustic properties of vowelless words: Since Tashlhiyt exhibits low consonant-to-consonant coarticulation, the presence of robust consonantal cues in the speech signal means that the internal phonological structure of vowelless words is recoverable by listeners. At the same time, word-likeness ratings of nonwords indicated that listeners relied on their native-language experience to judge the wellformedness of new words: Tashlhiyt listeners were most likely to accept obstruent-centered vowelless words; meanwhile, English listeners’ preferences increased with higher sonority values of the word center. Across both experiments, speech style variation provided further evidence as to how the phonetic implementation of vowelless words makes them perceptually stable. Thus, our findings provide an overview of the low-level acoustic-phonetic and higher-level phonological processing mechanisms involved in the perception of vowelless words. Our results can inform understandings of the relationship between language-specific phonetic variation and phonotactic patterns, as well as how auditory processing mechanisms shape phonological typology.

Published: December 2023

The features of the construction of a computational algorithm for calculating circular suction sockets in the conditions of an incoming flow by the method of discrete vortex rings are considered. Flow patterns are given at different ratios of the incoming and intake air flow velocities. The dependences of the characteristic sizes of vortex zones arising at the inlet to the suction-sockets on the velocity of the incoming flow, the length and angle of inclination of the socket are determined. Expressions are obtained for the critical velocity of the incoming flow, at which the flow separation mode for the first vortex zone changes from separation inside the bell to separation outside it. The obtained results can be useful for the construction of local suction systems, profiled according to the found outlines of vortex zones.
Invalidity of Election Results: Concept and Features of Constitutional and Legal Nature
Authors: Ignatenko Victor
Published: December 2023

The article is devoted to the research of the special constitutional and legal nature of invalidity of results of elections. The approaches expressed in the legal literature to understanding and interpreting the invalidity of the election results as a category of constitutional law are analyzed. The author's determination of invalidity of election results is proposed. The invalidity of the election results as a constitutional and legal category should be understood to mean the irreparable legal defect of the held elections established by the decision of the jurisdictional body (election commission or court) within its competence, which, in connection with violations of the electoral law, does not reveal the actual will of voters and entails legal nullity (lack of legal effect) of their result. The invalidity of the voting results is meant to mean the irreparable legal defects of the voting conducted in a certain part of the territory of the constituency established by the decision of the jurisdictional body (election commission or court) within its competence, which, due to violations of the voting rules, the establishment of voting results and other electoral procedures, does not allow to establish the actual will of voters and entails the legal nullity of the results of such voting. The article justifies the conclusion that the invalidation of the election results is a restorative measure (measure of protection) of constitutional and legal coercion.
Among the main shortcomings of modern constitutional and legal regulation of invalidation of election results, the following circumstances are noted in the article: 1) the legislator does not give a legal definition of constitutional and legal terms ≪invalidity of voting results≫ and ≪invalidity of election results≫; 2) the current electoral legislation contains a single list of grounds both for invalidating the results of the vote and for invalidating the results of the election; 3) in the regulation of the grounds for recognizing the voting results and election results as invalid, the texts of the current election laws dominate the assessment signs over the formally defined ones. According to the author, these deficiencies in the current electoral law seriously complicate the work of the courts in resolving electoral disputes about the invalidity of elections.
Using Special Knowledge: History, Status and Prospects of Development
Authors: Egorov Nikolay , Protasevich Alexander
Published: December 2023

The authors use normative sources to examine the history of the emergence and development of special knowledge in Russia, starting with the Decree of March 6, 1699 “On the Order of Investigating Signatures in Servitude Acts …”, and ending with the current legislation. Special knowledge is understood as systematized scientific knowledge and skills in the fields of science, technology, art or craft (with the exception of any knowledge in the field of law), a product of purposeful professional training and practical experience, used for collecting and examining evidence with the goal of establishing circumstances to be proven in a criminal case. The division of special knowledge into procedural and non-procedural is examined. The procedural forms of using special knowledge are further analyzed as those having evidentiary significance, namely: immediate use of special knowledge by the investigator himself; involving a specialist in investigatory actions; report and evidence of an expert; report and evidence of a specialist. Special attention is paid to the expert’s report as the key historical form, and the specialist’s report, whom the will of the lawmaker made a competitor of the former. It is noted that at the stage of preliminary investigation this competition favors the expert’s report, as, contrary to the specialist’s report, the law has provisions for the situations when the expertise is obligatory, and the expert is liable for false evidence, which is not the case with the specialist’s report; the expert has a right to conduct instrumental research, often involving partial or complete destruction or modification of objects, or changes to their appearance or key features, which is not typical for the specialist, since the specialist’s report is a written representation of his opinion on the questions posed before him by the sides; the form of the expert’s report is regulated by normative legal acts in detail, while there are no such regulations the specialist’s report. The authors analyze the prospects of using special knowledge: bringing the research process as close to the crime scene as possible, which it was suggested to call “field criminalistics”; using new research methods, researching new objects, mainly through the application of computer- and nano-technologies, as well as genomic objects; the objectivation of the testimonies of criminal proceeding’s participants, specifically, detecting lies by scanning their brains with classic magnetic resonance imaging after an effective prohibition of psycho-physiological examination with a polygraph.
The Tax Burden as One of the Conditions Contributing to the Shadow Economy in the Russian Regions
Authors: Fedotov Dmitry
Published: December 2023

The article is devoted to the study of conditions conducive to the growth of the shadow economy in Russian regions. Special attention is paid to assessing the impact of the tax burden on the scale of the shadow economy. The article is devoted to the study of the shadow economy in the Russian regions. The purpose of the study is to identify the characteristics by Russian regions with a high level of the shadow economy. In the study the methods of correlation analysis, factor analysis, and cluster analysis were used. The research revealed an inverse correlation between the amount of shadow employment and the level of the tax burden. In the regions with a low level of tax burden, a significant level of shadow employment is usually observed. There is also an inverse correlation between the value of shadow employment and labor productivity, measured by the value of Gross Regional Product (GRP) per capita. An inverse correlation was found between the scale of the shadow economy and the level of development of innovation processes in the region, which is measured by the number of advanced production technologies used per capita and the level of innovation activity of organizations. The study revealed an inverse correlation between the level of shadow employment and the share of industries in GRP, the correlation coefficient in 2019 was –0.5198. A direct correlation was found between the level of shadow employment and the share of social sectors in GRP, in 2019 the correlation coefficient was 0,5890. The obtained results allowed us to identify the factors that favor the growth of the shadow economy. Among them, the backlog of the regions in economic and innovative development comes to the fore. The research findings can be used by the state authorities for developing regional economic policies aimed to reduce the scale of the shadow economy.
Estimated Liabilities as an Object of Accounting in the Public and Non-Public Sectors of the Economy
Authors: Arbatskaya Tatyana , Putyrskaya Yana
Published: December 2023

The specifics of the activities of economic entities in the state and non-state sectors contributed to the isolation of accounting subsystems in these sectors, each of which was formed based on its organizational, technical and methodological foundations. Currently, the development of accounting in the Russian Federation is carried out in these sectors in accordance with IFRS in parallel, through the development of new federal accounting standards, the content of the norms of which often differ in relation to the same accounting objects. At the same time, the existing features of the organizations' activities in each sector should not cause discrepancies in approaches to the recognition and accounting of similar objects. In our opinion, developing federal standards, uniform approaches should be applied to the definition of objects, their classification, recognition, evaluation and disclosure of information about them in the reporting. One of the most difficult objects of accounting in both the public and non-governmental sectors are estimated liabilities. This article is devoted to the problematic aspects of their recognition and accounting through the creation of provisions. The result of the study is a comparative analysis of the legal regulation of the creation of provisions for estimated liabilities and the identification of problems of their formation in practice. This made it possible to classify provisions according to the criterion of the possibility of discounting them. It is offered to expand the list of grounds for creating provisions.
New Cities in Siberia as Drivers of Spatial Development: Challenges and Prospects
Authors: Meteleva Elena , Svetnik Tamara
Published: December 2023

The aim of this article is to identify possible problems relating to the implementation of the idea of founding new cities in Siberia that Sergei Shoigu had proclaimed. The author examines the applicability of such an initiative, as well as the resources and potentials of its implementation. The research conducted using the systems-thinking approach has led to the conclusion that it is necessary to make special governmental decisions on the formation of new large urban territories. The author found that the application of the cluster approach and industrialization by themselves are insufficient measures. Modern high-tech industries do not require a large number of employees and therefore do not provide a concentration of population in the locations of industrial enterprises. In view of this circumstance, the implementation of the idea of attracting the population to new Siberian cities and its consolidation there is possible only by increasing the diversity of the structure of urban economies. The author makes a suggestion that the most serious risks are the lack of diversification of urban economies and the inability to attract people without developing special solutions to increase the attractiveness of new settlements.
Corporate Culture Challenges in the Wake of COVID-19: Alibaba Group Case
Authors: Bogodelnikova Lyubov , Shuo Mu
Published: December 2023

The COVID-19 pandemic, having changed the organizational environment of the company, has become a serious test for the corporate culture. Unfortunately, there are not many studies devoted to how crisis situations affect the corporate culture of enterprises. The purpose of the study is to find out how the pandemic has affected the corporate culture of companies. The goal set required a deeper understanding of the concept and functions of corporate culture, as well as an analysis of possible problems of corporate culture management in crisis. The starting point for the study was the idea that without a well-formed corporate culture it is impossible to build a strategy for the sustainable development of the company. A hypothesis was put forward that with a change in the external environment, working conditions and organization of the workplace in a crisis situation, the basis of corporate culture, namely the values that make up its basis, remain unchanged. Using the desk research, we analyzed the measures taken by the leadership of the Chinese company Alibaba Group to solve the organizational problems caused by the COVID-19 pandemic, and to find out whether these measures were in line with the corporate culture of the company. The study led to the conclusion that it was the preservation of the deeply-rooted values shared by all employees that allowed Alibaba Group to survive in turbulent times of crisis. These partial conclusions can be used to assess the possible global consequences of a change in corporate culture in pandemic, as well as lay the basis for future research.

Published: December 2023

Aim of study: This study investigates the estimation success of using day and night segments in producing Forest Canopy Cover (FCC) maps with the Canopy Cover Estimation Model (CCEM) for the years 2020 and 2022.

Area of study: The study area covers 17 interconnected counties situated in the southeastern part of Texas state, adjacent to the state of Louisiana, and near the southern coastlines, known for their extensive forested areas.

Material and methods: This study incorporated both day and night acquisition segments from Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) data for a comprehensive comparison of their effectiveness in mapping the forest canopy cover using the CCEM.

Main results: The study’s findings reveal that night segment-derived FCC maps outperform those derived from day segments, showing higher kappa coefficients of 0.77 and 0.83 for the years 2020 and 2022, respectively. In addition, notable differences were observed among classes of FCC estimations successes for day and night segment-derived maps.

Research highlights: This study introduces a significant finding that the FCC maps derived from night segments yield more accurate results than those derived from day segments. The study further discovers a notable difference in the forest canopy cover classification success, particularly with a lower accuracy observed in the Moderate Forest Canopy Cover (MFCC) category.
DEVELOPMENT OF A METHOD FOR CALCULATING LOADS ON IMPLANTS AND PROSTHESES USED FOR THE HUMAN SKELETON
Authors: TUNC Ismet Emircan , ŞEFKAT Gürsel
Published: December 2023

The study proposes a novel computational approach for customizing sustainable knee disarticulation prostheses, aimed at improving the quality of life for users. A specialized calculation technique for assessing the loads and moments on the prosthesis was formulated, leveraging MATLAB for solving kinematic equations, Solidworks for motion analysis, and ANSYS Workbench for material and static analysis. The integration of these tools enabled the validation of the design and analytical outcomes. The kinematic solutions accounted for individual and prosthesis weights, analyzing linear and angular dynamics over a motion range pertinent to the prosthetic leg's function. Static analysis was executed to determine maximum force impact on the prosthesis. The study's results were conducive to identifying the most suitable prosthesis characteristics for individuals aged 20 to 80, with a height of 160-190 cm and a weight of 80-120 kg. The prosthetic design promoted ease of movement in activities requiring a range of motion, such as running and jumping. The prosthesis adapted swiftly to body movements, achieving readiness in approximately three seconds. The research underscores the importance of interdisciplinary collaboration between engineers and medical professionals to optimize the anatomical and kinematic aspects of prosthesis design.
THE EXPLOITATION OF TITANIUM DIOXIDE NANOPARTICLES FOR IMPROVING THE PERFORMANCE AND EMISSIONS OF BIOFUEL-DIESEL BLEND-FUELLED STATIONARY DIESEL ENGINE
Authors: ÇAKMAK Abdülvahap
Published: December 2023

In this research, the potential effects of titanium dioxide (TiO2) nanoparticles on improving a stationary diesel engine characteristic fuelled with a biofuel mixture-diesel blend (B25: 25% vol. biofuel mixture containing biodiesel, waste cooking oil and ethanol + 75% vol. diesel) are experimentally investigated. TiO2 nanoparticles are dispersed in B25 fuel at 50, 100, and 150 ppm concentrations. Subsequently, they are tested in a stationary research diesel engine at a rotational speed of 1500 rpm and specific loads. Nanoparticles enhance combustion, offering increased cylinder gas pressure, net heat release rate, and reduced ignition delay period and combustion duration. The engine performance is enhanced more with increasing nanoparticle concentration. TiO2 nanoparticles with a 150 ppm rate reduce brake-specific fuel consumption by 3.21% and increase the brake effective efficiency by 3.67%, on average, compared to B25 fuel without nanoparticles. CO emission and smoke opacity are reduced by up to 31.89% and 24.56% with TiO2 nanoparticles. However, under the same operating conditions, NO emission increases to 30.58% compared to sole B25. Nevertheless, the NO emission of nanofuels is still less than that of diesel fuel. This study's results indicate that using TiO2 nanoparticles as a nano fuel additive can enhance the stationary engine's operation fueled with the biofuel mixture-diesel blend.

Effect of Glossing on Chinese Senior High School EFL Learners’ Vocabulary Acquisition
Authors: Zhu Yeqiu
Published: December 2023

This study examined the effects of four types of glosses on Chinese EFL learners’ vocabulary acquisition. The participants were 175 senior high school students, who were divided into five groups according to different glossing conditions: L1 glosses, L2 glosses, multiple-choice L1 glosses, multiple-choice L2 glosses, and no glosses. The participants were asked to read an English material that contained ten target pseudo-words. They then took an immediate vocabulary post-test, which consisted of two recognition tasks and two recall tasks. Two weeks later, they took an unexpected delayed vocabulary post-test with the same tasks. The findings revealed that glossing had a significantly positive effect on the learners’ vocabulary learning. Single L1 glosses were the most effective among the four types of glosses, while multiple-choice L2 glosses were the least effective. It was also found that the four types of glosses produced better effects on vocabulary acquisition in the recognition tasks than in the recall tasks and that all the gloss groups had better short-term word retention than long-term one, except for the single L2 gloss group, which displayed the opposite effect.
Strength analysis of welded joints in support structures of heavy machinery subjected to changeable loading conditions
Authors: Smolnicki Tadeusz , Sokolski Piotr
Published: December 2023

The durability of bearing units of large machines depends mainly on the condition of their welded joints. With this in mind, we developed numerical models of the analyzed bearing units, for which we performed FEM simulations of the stresses in welded joints in several basic load cases. In each of the respective variants the technical condition of the bearing nodes was different and it corresponded to the severity of the degradation processes. Different positions of the superstructure in relation to the undercarriage were also taken into account. The simulations used the hot-spot method dedicated to FEM analyses of complex welded structures. We discovered that the loads have a significant influence on the values and distribution of von Mises principal stresses and their axial components. Based on the carried out analyses, we identified the most unfavorable load cases that generate the highest stresses in the welded joints of the assessed nodes. We also demonstrated that the applied method effectively assesses the stresses of welded joints subjected to variable working loads.
Does Context Matter? Governance Models in Local Administration
Authors: Vedder Stefanie , Friedländer Benjamin , Bogumil-Uçan Simon , Klenk Tanja
Published: December 2023

Purpose: Over the past decades, public administration scholars and practitioners around the world have experimented with various administrative reforms to design governance models suitable to fulfil the tasks of public administration. Amidst this ongoing debate, (at least) three different and competing governance models can be distinguished: New Public Management, New Public Governance, and the (Neo-)Weberian model. Despite each of these models claiming universal legitimacy, specific administrative branches in different administrative systems operate in unique contexts and handle varying tasks. The article delves into the question of whether and to what extent different branches of public administration within the same administrative system adopt global public administration ideas in a similar fashion.Design/Methodology/Approach: The article employs a comparative design to analyse the adoption of global public administration concepts across different administrative branches. Given their shared rigid Weberian tradition but divergent tasks and context, the study uses the German financial and social administrations as examples. The findings are derived from a survey of local agencies.Findings: The study reveals a persistent influence of strong Weberian traditions on the structural and operational makeup of both branches, indicating a significant path dependency in governance understanding. The characteristics of New Public Management and New Public Governance are comparatively more prominent in social than in financial administration, which can be attributed to differences in tasks and relations, especially with political actors.Academic contribution to the field: In addition to supplementing existing detailed analyses of the (non-)success of specific public administration reforms, the study takes a comprehensive view of the long-term development of public administration structure and perception, spanning multiple reforms. While acknowledging the formative influence of administrative tradition on the entire public administration system, the focus is on the nuanced effects of administrative traditions on diverse organisations, encouraging future comparative research.Originality/Significance/Value: In addition to the contribution to the field, our comparative methodology and empirical study makeup show the advantages of concentrating on a minimal number of paradigms that can be delineated as clearly as possible, instead of operationalising public administration reforms with a multitude of (potentially country-specific) indicators. With this approach, we lay the groundwork for the extension of the comparative design to other countries and administrative systems.

Published: December 2023

This panel report outlines key insights from the Hello Diversity! Hackathon on gender equality in the workplace held digitally in November 2020. The one-day event with more than 150 participants featured panel discussions and ideation sessions to enable the participants to develop innovative tools, strategies, and processes to minimize gender inequality in workforces involved in digital innovation. Overall, the hackathon aimed to build bridges between research and practice to derive answers on how existing barriers towards more gender equality in digital innovation processes and outcomes can be addressed. The theoretically informed challenges that were tackled during the event concerned topics such as stereotypes and discrimination, incentivizing workforce equality, and necessary support infrastructures in public and private spheres. The developed solutions indicate that much remains to be done to address the lack of processes, organizational structures, and holistic knowledge regarding the importance and benefits of diversity and inclusion in digital innovation. The hackathon culminated in pitches made on the envisioned solutions to kick-start their implementation and encourage research support and progress.

Role of Infrapatellar Fat Tissue in the Pathogenesis of Knee Osteoarthritis: A Review
Authors: Korneva Yulia S. , Borisenko Marina B.
Published: December 2023

Osteoarthritis (OA) is one of the most common joint diseases in the adult population. The role of indolent inflammation and predominance of catabolic cytokines over anabolic ones in OA has now been proven. The influence of obesity on the development of OA by releasing inflammatory mediators by fat tissue has been confirmed. Infrapatellar fat tissue (Hoffa’s fat pad) is a potential donor of proinflammatory cytokines, including specific fat tissue proinflammatory cytokines - adipokines. In a healthy person, infrapatellar fat tissue contributes to the distribution of mechanical load on the joint and metabolism of the synovial fluid. Infiltration of infrapatellar fat tissue by macrophages and lymphocytes leads not only to the production of proinflammatory cytokines with chondrolytic properties, but also to the maintenance of chronic inflammation in the synovial membrane, articular cartilage, and subchondral bone. Morphologic changes in Hoffa’s fat pad can be both an indicator of the inflammatory process in the joint cavity and a predictor of pathologic changes of the joint. Among histological changes, infiltration with macrophages and lymphocytes, fibrosis, thickening of the interlobular septa, reduction in the size of fat lobules and adipocytes, and increased vascularization are important for the course of OA. Morphologic changes can be assessed using a non-invasive method - magnetic resonance imaging, which makes it possible to evaluate the presence and severity of synovitis, thickening of the synovial membrane, edema, thickening of the interlobular septa, and a decrease in the volume of Hoffa’s fat pad. Histologic and tomographic signs can potentially be used to assess the severity of OA and develop prognostic scales. Infrapatellar fat tissue is also a source of mesenchymal stem cells phenotypically similar to chondrocytes, which can be used for regeneration of joint cartilage tissue with minimally invasive intervention to harvest them.
Early Childhood Education Leader Stories as Social Justice Praxis

Published: December 2023

This qualitative research explored the experience of eight Early Childhood Education (ECE) leaders invited to engage in telling their leader stories. Leader stories refers to the narrative descriptions that leaders provide about themselves, their leadership, and their leadership practices. This research engaged leaders in the consideration of several questions. These questions were: 1) How do ECE leaders describe their identities across domains of identity (e.g., race, gender, sexual orientation)? 2) How do ECE leaders understand and articulate the role of their personal identities in their leadership? 3) How do ECE leaders seek to understand the needs of children in their care and the impact of practices and policies on diverse learners? and 4) What impact do the narrative practices of self-inquiry, critical reflection, and dialogue have on an ECE directors' understanding of themselves as leaders who can be more responsive to the needs of diverse learners, e.g., lead towards social justice? Interconnectedness of the findings demonstrates that ECE leaders' stories of who they are, why they lead, how they serve children, and how they engage in work with social justice are tied to one another. The lived experiences and identities of leaders both in and outside of their leadership roles directly impacts their leadership and those they lead and serve. Engagement with reflection and inquiry is also embedded in their stories, suggesting that these leaders bring an openness to not just leading but to understanding how their leadership impacts their vision(s) to serve children. The findings suggest that tools that help leaders to see their own leadership and the interconnectivity of their identities might be useful in their practices. Several concrete applications of these findings are worth noting. The bridge between Capper's (2019) identity development model for leaders of social justice, Bronfenbrenner's (2005) model for child development, and Furman's (2012) outline of social justice leadership praxis is worth exploring more deeply. Inviting leaders to discover these interconnectivities may provide them a meaningful opportunity to expand their practices, deepen their awareness of the power of what they already do, and help newer leaders more explicitly own some of the ways they might understand and capitalize on these connections.
Work Will Not Save Us: An Asian American Crip Manifesto
Authors: Chen Mel Y. , Khúc Mimi , Kim Jina B.
Published: December 2023

Drawing together disability justice, Asian American studies, and feminist/ queer-of-color labor analysis, this collaboratively authored essay forwards an anti-work manifesto shaped by our lived experiences as sick, disabled and queer Asian American scholars laboring in the academic-industrial complex. This essay offers a two-part intervention: first, it aims to expand nascent conversations on disability politics and its relationship to racial capitalism, and second, it puts forth a critique of the Asian American emphasis on achievement as an instrument of belonging and potential inoculation against racialized violence. It also unfolds in two parts: first, a section on why we refuse work, and second, a section on how to perform this refusal.

 

As we come to this essay from our respective positionalities in contingent, tenure-stream, and tenured academic loci, as well as from our shared investments in feminist and queer frameworks, the first section mobilizes feminist and queer disability analysis to interrogate the fraught investments in work shared across Asian American and Disability Studies, addressing the complexities of gendered, contingent, care, and service work within the academic landscape (and particularly as we have experienced them). The second section offers a survival guide for navigating the labor demands placed on racialized, queer, and/ or disabled scholars, channeling Asian American rage to move beyond saying “no” and toward saying “fuck off.”
OS CRENTES SEM RELIGIÃO E A BUSCA DE SENTIDO
Authors: Ecco Clóvis , Lemos Carolina Teles
Published: December 2023

Estamos vivendo em um contexto de profundas transformações socioculturais, no qual as religiões tradicionais perdem espaços e as fontes de sentidos dos crentes sem religião crescem rapidamente. Este artigo tem como objetivo analisar como e em que os crentes sem religião na atualidade estão buscando e encontrando sentidos em suas vidas na hodiernidade. Para tal, realizamos uma investigação empírica qualitativa, através de entrevista semiestruturada, aplicando questionário com perguntas fechadas e abertas, a participantes de cursos de Psicologia Transpessoal, na UNIPAZ Goiás, no período de 2020-2021 . Tanto os dados empíricos quanto os bibliográficos foram analisados à luz do pensamento de Marià Corbì, no que se refere às diferentes formas e fontes de sentidos na atualidade. Concluímos que estamos saindo de uma forma de sociedade cujas relações eram marcadas pelas hierarquias, submissões e ortodoxias políticas, econômicas e religiosas e passando para formas de relações com poderes mais compartilhados e baseadas em decisões e ações mais livres, individuais e autônomas. As mudanças nas formas e fontes de sentidos no que se refere à religião se inserem nesse processo.
