Published: May 2023

Pollution is one of the most pressing issues of modern times. Effluent in the world is escalating due to the exponential growth in the industrial and agricultural sectors. The effluents contain heavy metals, pesticides, and inorganic substances ultimately leading to the deterioration of the ecosystem. Even though there are numerous wastewater treatment methods like adsorption, membrane separation, ion exchange, and physical, mechanical, and chemical treatments. They are expensive and have the risk of second-hand pollution. Biopolymers are alternate and superior to synthetic polymers due to their environmentally friendly approach and high efficiency in treating wastewater. The most prominent plant-based biopolymers for the treatment of pollutants are cellulose, starch, carrageenan, alginate, xylan, inulin, pectin, and tragacanth. These have their advantages and disadvantages in bioremediation. The mechanism of pollution removal has adsorption, flocculation, bridge formation, and electrostatic patches. They are biodegradable as they are natural in origin. They have proved to remove toxic pollutants like chitosan, pullulan, polyhydroxy alkonates and butyrates, dextran, starch and cellulose, polyvinyl alcohol and polycaprolactone, gelatin, collagen and wheat gluten, alginate, heparin, and pectin to name a few. Biopolymers are also sourced from diverse sources like agricultural wastes and well-known sources like plants, animals, and microbes. Biopolymer and its composites are utilized as coagulants and flocculants. They are cellulose graft polyacrylamide, anionic sodium carboxymethylcellulose, guar gum graft polyacrylamide, pectin polyacrylamide, starch, and tannin. Nanotechnology has led to the development of elite nanohybrid bio-adsorbents to actively remove pollutants. These nano adsorbents have been targeting pollutants like azo dyes, bovine serum albumin, cationic dyes, parabens, and methylene blue among others. Biopolymer composites are also widely used for diverse applications primarily due to their enhanced mechanical and thermal properties. Biopolymers from natural and synthetic sources can be modified and used as per the requirement.

Los plaguicidas alteran la calidad del agua y afectan a los usuarios en la cuenca del Río Turbio, México. El objetivo principal de este estudio fue identificar las prácticas y percepciones locales en torno al manejo de los plaguicidas en los municipios de San Francisco y Purísima del Rincón y Manuel Doblado, Guanajuato. Se realizó un estudio transversal con 69 encuestas para muestras de agricultores, proveedores y representantes institucionales, durante septiembre a noviembre de 2021. Los resultados se analizaron de manera descriptiva para identificar las sustancias e impactos más reportados por los usuarios. Se añadió la cuantificación de impacto a la salud y medio ambiente para dichas sustancias. Los plaguicidas más utilizados fueron la cipermetrina, lamda-cialotrina, clorpirifos, fenvalerato y malatión, además de los herbicidas topramezone, 2,4-D, glifosato y paraquat, los cuales se valoraron de poco a moderadamente peligrosos para la salud y de alto a muy alto peligro al ambiente, según los resultados de la valoración de impacto. Las prácticas de uso indican que casi el 50% de agricultores dosifican en base a la etiqueta, el 98% refiere que se protege solo con elementos básicos, y el 48% reportan síntomas de toxicidad aguda (mareo, vómito e intoxicación), irritación ocular o cutánea y sensibilidad respiratoria. Futuras acciones como capacitaciones adecuadas, concientización en seguridad e higiene, disposición de envases y transferencia de conocimiento a tomadores de decisión local son necesarias para reducir los riesgos a la salud, al ambiente y a la producción agrícola.
POESIA – CORPO – LIBERDADE EM MARIA TERESA HORTA
Authors: Vasconcelos Michelle , Santos de Oliveira Rodrigo
Published: May 2023

Maria Teresa Horta (1937-) é um dos nomes mais importantes da literatura de autoria feminina em Portugal do século XX. A sua produção tem início durante a ditadura salazarista, e se caracterizou por um forte combate ao regime, o que lhe rendeu duras perseguições políticas. Desta maneira, a sua produção do período deve ser analisada com um atento olhar histórico e político, visto que o viés ideológico político perpassa toda a sua produção, principalmente nas publicações entre 1961 e 1977, ano em que publica Mulheres de Abril. Diversas foram as suas formas de se expressar e se manifestar contra o regime político vigente, entretanto, o uso da imagem do corpo feminino e das questões inerentes ao sujeito feminino na sociedade portuguesa da época, como forma de resistência ao Estado Novo, são talvez as que se tornaram mais características de sua obra, e motivo pelo qual hoje é amplamente conhecida. Desta maneira, o presente se propõe a analisar a relação que Teresa Horta constrói entre poesia, corpo e liberdade na sua produção entre 1971 e 1977, tomando em consideração o contexto político vigente, as suas ações e participações políticas e as políticas estatais em relação à mulher.Palavras-chave: Ditadura; Poesia; Corpo; Feminismo; Maria Teresa Horta. POETRY- BODY- FREEDOM IN MARIA TERESA HORTA’S WRITINGSAbstract: Maria Teresa Horta (1937-) is one of the most important names in women's literature in Portugal in the 20th century. Her production started during the Salazar dictatorship, and was characterized by a strong fight against the regime, which resulted in harsh political persecutions. In this way, her production from the period must be analyzed with a careful historical and political view, since an ideological political slant permeates her entire production, mainly in the publications between 1961 and 1977, the year in which she published Mulheres de Abril. There were seve­ral ways of expressing and manifesting against the current political regime, howe­ver, the use of the image of the female body and the issues inherent to the female  subject in Portuguese society at the time, as a form of resistance to the Estado Novo, are perhaps what has become to be seen as more characteristic of her work, which is why it is widely known. Thus, this paper intends to analyze the relationship that Teresa Horta builds between poetry, the body and freedom in her production be­tween 1971 and 1977, taking into account the political context in vigor, her political action and participation, as well as the state policies in relation to women. Keywords: Dictatorship; Poetry; Body; Feminism; Maria Teresa Horta.

Incidence, Predictors and Associations Between In-Hospital Bleeding and Adverse Events in Patients with Acute Coronary Syndrome Above 75 Years of Age – The Real-World Scenario
Authors: Wei Cheng , Zhu Zhaowei , Hu Xinqun , Zhou Shenghua
Published: May 2023

Background: Bleeding events in patients with acute coronary syndrome (ACS) are associated with poor outcomes. Risk factors and their associations with in-hospital events in older patients with ACS are not fully understood, because older patients with ACS are often excluded from randomized controlled studies.

Methods: We enrolled 962 patients with ACS above 75 years of age treated at our center between January 2012 and December 2016. The incidence and risk factors for in-hospital bleeding events, as well as their associations with in-hospital adverse events were evaluated.

Results: Bleeding complications were observed in 38 patients (4.1%). The most common bleeding site was the gastrointestinal tract (52.6%). Anemia (P=0.007), renal insufficiency (P=0.019), use of positive inotropic medicines (P=0.006) and elevated leukocyte count (P=0.046) were independent predictors of in-hospital bleeding after adjustment for age, sex, atrial fibrillation history and hypertension history. In-hospital mortality (28.9% vs. 2.4%, P<0.001), stroke (5.3% vs. 0.5%, P<0.001) and the prevalence of heart failure (39.5% vs. 16.3%, P<0.001) were significantly higher in patients with than without bleeding.

Conclusions: The incidence of in-hospital bleeding was 4.1% in patients with ACS above 75 years of age in this cohort. Independent risk factors for in-hospital bleeding events included anemia, renal insufficiency and elevated leucocyte count. Bleeding events were strongly associated with in-hospital adverse events.
On the Tonotopy of the Low-Frequency Region of the Cochlea
Authors: Recio-Spinoso Alberto , Dong Wei , Oghalai John S.
Published: May 2023

It is generally assumed that frequency selectivity varies along the cochlea. For example, at the base of the cochlea, which is a region sensitive to high-frequency sounds, the best frequency of a cochlear location increases toward the most basal end, that is, near the stapes. Response phases also vary along cochlear locations. At any given frequency, there is a decrease in phase lag toward the stapes. This tonotopic arrangement in the cochlea was originally described by Georg von Békésy in a seminal series of experiments on human cadavers and has been confirmed in more recent works on live laboratory animals. Nonetheless, our knowledge of tonotopy at the apex of the cochlea remains incomplete in animals with low-frequency hearing, which is relevant to human speech. The results of our experiments on guinea pig, gerbil, and chinchilla cochleas, regardless of the sex of the animal, show that responses to sound differ at locations across the apex in a pattern consistent with previous studies of the base of the cochlea.

SIGNIFICANCE STATEMENTTonotopy is an important property of the auditory system that has been shown to exist in many auditory centers. In fact, most auditory implants work on the assumption of its existence by assigning different frequencies to different stimulating electrodes based on their location. At the level of the basilar membrane in the cochlea, a tonotopic arrangement implies that high-frequency stimuli evoke largest displacements at the base, near the ossicles, and low-frequency sounds have their greatest effects at the apex. Although tonotopy has been confirmed at the base of the cochlea on live animals at the apex of the cochlea, however, it has been less studied. Here, we show that a tonotopic arrangement does exist at the apex of the cochlea.

Previous studies have shown the essential roles of O-GlcNAc transferase (Ogt) and O-GlcNAcylation in neuronal development, function and neurologic diseases. However, the function of Ogt and O-GlcNAcylation in the adult cerebellum has not been well elucidated. Here, we have found that cerebellum has the highest level of O-GlcNAcylation relative to cortex and hippocampus of adult male mice. Specific deletion ofOgtin granule neuron precursors (GNPs) induces abnormal morphology and decreased size of the cerebellum in adult maleOgtdeficient [conditional knock-out (cKO)] mice. Adult male cKO mice show the reduced density and aberrant distribution of cerebellar granule cells (CGCs), the disrupted arrangement of Bergman glia (BG) and Purkinje cells. In addition, adult male cKO mice exhibit aberrant synaptic connection, impaired motor coordination, and learning and memory abilities. Mechanistically, we have identified G-protein subunit α12 (Gα12) is modified by Ogt-mediated O-GlcNAcylation. O-GlcNAcylation of Gα12 facilitates its binding to Rho guanine nucleotide exchange factor 12 (Arhgef12) and consequently activates RhoA/ROCK signaling. RhoA/ROCK pathway activator LPA can rescue the developmental deficits ofOgtdeficient CGCs. Therefore, our study has revealed the critical function and related mechanisms of Ogt and O-GlcNAcylation in the cerebellum of adult male mice.

SIGNIFICANCE STATEMENTCerebellar function are regulated by diverse mechanisms. To unveil novel mechanisms is critical for understanding the cerebellar function and the clinical therapy of cerebellum-related diseases. In the present study, we have shown that O-GlcNAc transferase gene (Ogt) deletion induces abnormal cerebellar morphology, synaptic connection, and behavioral deficits of adult male mice. Mechanistically, Ogt catalyzes O-GlcNAcylation of Gα12, which promotes the binding to Arhgef12, and regulates RhoA/ROCK signaling pathway. Our study has uncovered the important roles of Ogt and O-GlcNAcylation in regulating cerebellar function and cerebellum-related behavior. Our results suggest that Ogt and O-GlcNAcylation could be potential targets for some cerebellum-related diseases.

In this paper, the effect of using different configurations of absorber plate, including one line finned flat absorber and two lines finned absorber plate, on the thermal performance of a flat plate – double passing solar air heater was investigated experimentally. L- shape fins are soldered on the absorber plate to roughen the absorber plate and generate vortices to enhance the heat transfer between the working fluid (air) and absorber plate to improve the thermal efficiency. The outdoor experimental test was carried out during February and May under the weather conditions of Baghdad city (Longitude 33.3 N and Latitude 44.44 E). The results show that the air temperature is 48 ℃, 47.5 ℃, and 58.5 ℃ at an air velocity of 1.7 m/s for a single line of fins which increased to 52 ℃, 57.5 ℃, and 66 ℃ at air velocity of 0.9 m/s for two lines of fins. The efficiency is increased by 28% for one line of fins and 66% for two lines of fins at an air velocity of 0.9 m/s while increased by 27% for one line of fins and 51% for two lines of fins at an air velocity of 1.7 m/s. The average exergy destruction rate increases by 37.6%, 60.6%, and 68.66% for the absorber plate, working fluid, and glass cover, respectively, for velocity increase from 0.9 m/s to 1.9 m/s. The exergy efficiency increased by 24.1% when the velocity increased from 0.9 m/s to 1.9 m/s.

Published: May 2023

Big Data Analytics is widely adopted by large companies but to a lesser extent by small to medium-sized enterprises (SMEs). SMEs comprise 99% of all businesses in the UK (6 million), employ 61% of the country’s workforce and generate over half of the turnover of the UK’s private sector (£2.1trillion). SMEs represent 99% of all businesses in Europe and 90% worldwide. Therefore, assisting them to gain competitive advantage by the adoption of technology, such as Big Data Analytics is an important business initiative. The aim of this paper is to outline the process in which a positioning tool based on theoretical frameworks has been developed to help SMEs analyse their readiness to adopt Big Data Analytics using a case study. Previous work has identified 21 barriers to adoption and a methodology based on theoretical frameworks was developed to produce a positioning tool Holistic Big Data Analytics Framework for UK SMEs(HBDAF-UKSMEs).The paper outlines a case study based on a software development company to utilise this HBDAF-UKSMEs framework to assess the readiness using the proposed scoring tool for the adoption of Big Data Analytics based on three stages: pre-data analytics, business intelligence and Big Data Analytics.

Face classification is a challenging task that is crucial to numerous applications. There are many algorithms for classifying gender, but their ability to evaluate their effectiveness regarding scientific data is constrained. Deep learning is popular among researchers in face classification problems. The detection of many faces is complicated and becomes a necessity in real problems. The proposed research aims to examine the effect of twofold face detection approach on the accuracy of gender classification, as well as the effect of using small datasets on accuracy. In this study, we use a small dataset to classify facial images based on their gender. The following phases involve deep learning methods along with the OpenCV library version 3.4.2 which is recommended to serve as a twofold face detection approach. In the experiments conducted, Phase 1 is the designated training phase, and Phase 2 serves as a testing phase. Two different algorithms are used in the testing phase to detect one face in the image (Experiment 1), while the remaining algorithm detects multiple faces in the image (Experiment 2). The FEI dataset is used to evaluate the accuracy of the proposed research, which results in 84% accuracy for Experiment 2 and 74% for Experiment 1, respectively.

In brief

The concentration of progesterone through the estrous cycle modulates uterine function to affect the luminal metabolome. This paper reports that the dynamic changes in the bovine uterine luminal metabolome during diestrus are independent of the concentration of progesterone in the previous cycle.

In cattle, the concentration of sex steroids modulates uterine function, which is reflected in the composition of the luminal metabolome. Ultimately, the uterine luminal metabolome influences embryonic growth and development. Our objectives were (i) to compare the luminal metabolome 4, 7, and 14 days after estrus of cows that were exposed to greater (HP4; n = 16) vs lower (LP4; n = 24) concentrations of progesterone before displaying estrus and ovulating spontaneously and (ii) to identify changes in the luminal concentration of metabolites across these time points. Luminal epithelial cells and fluid were collected using a cytology brush, and gene expression and metabolite concentrations were assessed by RNAseq and targeted mass spectrometry, respectively. Metabolome profile was similar between treatments within each of days 4, 7, and 14 (false discovery rate (FDR): ≥ 0.1). Concentrations of 53 metabolites changed, independent of treatment, across the diestrus. Metabolites were mostly lipids (40 out 53) and the greatest concentrations were at day 14 (FDR: ≤ 0.1). On day 7, the concentration of putrescine and the gene expression of ODC1, PAOX, SLC3A2, and SAT1 increased (P ≤ 0.05). On day 14, the concentration of 3 ceramides, 4 glucosylceramides, and 12 sphingomyelins and the expression of SGMS2 were increased, in addition to the concentration of choline and 20 phosphatidylcholines. Collectively, the post-estrus concentration of luminal metabolites changed dynamically, independent of the concentration of sex steroids on the previous cycle, and the greatest magnitude changes were on day 14 when lipid metabolism was the most enriched pathway.
Archival performance of paper as affected by chemical components: A Review

Published: May 2023

For about two millennia, paper has served as a main medium for preservation of people’s ideas, stories, contracts, and art. This article reviews what is known about the various components that make up paper from the perspective of their long-term stability under typical storage conditions. Literature evidence is considered relative to the susceptibility of different paper components to embrittlement, acid hydrolysis, microbiological attack, and discoloration, among others. The cellulose that makes up a majority of most paper items is demonstrably stable enough to persist for many hundreds of years on the shelves of archival collections, though it is susceptible to acid-catalyzed hydrolysis, which can be accelerated by byproducts of decomposition. Though less attention has been paid to the archival performance of various minor components of modern paper products, evidence suggests that at least some of them are subject to likely breakdown, embrittlement, or decay in the course of prolonged storage. Based on these considerations, one can envision different categories of paper that can be expected to meet different levels of storage stability: ancient recipes for handmade papermaking, e.g. washi and hanji, archival-grade paper products, ordinary modern alkaline paper products, and paper manufactured without concerns for its longevity.

Mycobacterium fortuitum is a clinically important species among nontuberculous mycobacteria (NTM). Treatment of diseases caused by NTM is challenging. The aim of this study was identification of drug susceptibility and detection of mutations in erm(39) related to clarithromycin resistance and in rrl related to linezolid resistance in clinical isolates of M. fortuitum in Iran. In the study, 328 clinical NTM isolates were subjected to identification based on rpoB and 15% of isolates were assigned to M. fortuitum. Minimum inhibitory concentration for clarithromycin and linezolid was determined by E-test. Altogether 64% of M. fortuitum isolates showed resistanc to clarithromycin and 18% of M. fortuitum isolates showed resistance to linezolid. PCR and DNA sequencing were performed in erm(39) and in rrl genes for detection of mutations related to clarithromycin and linezolid resistance, respectively. Sequencing analysis revealed (84.37%) single nucleotide polymorphisms in the erm(39). A total 55.55% of M. fortuitum isolates harbored an A→G, 14.81% harbored an C→A, 29.62% harbored an G→T mutation in erm(39) at position 124, 135, 275. Seven strains harbored point mutation in the rrl gene either at T2131C or at A2358G. Our findings showed M. fortuitum isolates have become a serious problem with high-level antibiotic resistance. The existence of drug resistance to clarithromycin and linezolid indicates more attention to the study of drug resistance in M. fortuitum.

Published: May 2023

The cultural differences encountered while studying abroad can trigger problems that generate negative emotions. To prevent the negative impact of these emotions on the quality of life of students, it is important to have intercultural adjustments so that they can deal with cultural differences more adaptively. This study aims to explore the obstacles experienced by Indonesian students in Japan and how intercultural adjustment efforts are made. The research was conducted using descriptive qualitative methods through semi-structured interviews with two Indonesian students in Japan. Data analysis using thematic analysis. The results of the study found several themes of obstacles such as language barriers, difficulty socializing with local people, living systems due to differences in weather and climate, loneliness, and difficulty finding halal food. To overcome these obstacles, several themes of adjustment were made, including: emotional regulation, self opening, flexible, and evaluating new experiences and knowledge. These themes show that the adjustment of Indonesian students in Japan can be explained within the framework of intercultural adjustment.

HEAT FUNCTION ANALYTICS OF CONJUGATE NATURAL CONVECTION HEAT TRANSFER IN PARTITIONED ENCLOSURE FILLED WITH HYBRID NANOFLUID UNDER MAGNETIC FIELDS
Authors: Waheed M. A. , Enweremadu Christopher C.
Published: May 2023

The need for suitable control of fluid flow and heat transfer for enhanced performance has led to the use of magnetic fields, appropriate design and sizing of devices, and the right choice of flow governing parameters for many industrial processes. This study investigates the effects of uniform magnetic field on heat flow induced by buoyancy in a square enclosure partitioned into two cavities with a conducting solid body. The cavities are filled with hybrid nanofluid composed from water and equal proportion of Cu and Al2O3 nanoparticles. The problem is analyzed numerically by solving the momentum, energy, and heat function equations with the finite difference method. The governing parameters including the Rayleigh (Ra) and Hartmann (Ha) numbers, solid concentration of the hybrid nanoparticles (φ), and the ratio of the thermal conductivity of the hybrid nanofluid to that of the solid conducting partition wall (k*) are varied in the ranges of 103 ≤ Ra ≤ 108, 0 ≤ Ha ≤ 150, 0 ≤ φ ≤ 0.06, and 1 ≤ k* ≤ 20, respectively. The results show that the average temperature increases with the increase in the Ra and reduces with the increase in the values of the Ha, k*, and ф in the left cavity of the partition, but the reversed trend was obtained in the right cavity. The average heat function in the left cavity reduces with Ra and Ha while the overall fluid and heat flow are enhanced with the increase in the Ra and k* and retarded by increasing Ha. These results can be used as baseline data for the design and appropriate sizing of the heat transfer devices.

Introduction: Chlorine, ethyl alcohol, and quaternary ammonium are disinfectants with antiviral activity against SARS-Cov2. However, there are no previous reports of their use and handling for cleaning and disinfection in dental offices. Objetive: To determine the use and management of disinfectants in critical and non-critical areas used by dentists in San Luis Potosí, Mexico, during the COVID-19 pandemic. Material and Methods: A validated cross-sectional survey was applied online to 100 dentists in San Luis Potosí between February and June 2021. Participants were informed about the handling of personal data according to the standard DOF regulations (DOF 07-05-2010). Results: A total of 100 dentists were included in the study, 63% female and 37% male, with a mean age of 26 years. The most widely used disinfectants during the pandemic in critical areas were Lysol® and 0.1% sodium hypochlorite in non-critical areas. Eighty-five percent of dentists know the adverse effects of inappropriate use of disinfectants, 72% did not have any sign or symptom associated with the use of disinfectants. The most used protection barrier was gloves (97%). Sixty-seven per cent of dentists disposed of disinfectant waste down the drain. Conclusion: Sodium hypochlorite and quaternary ammonium compounds and/or ethanol are used to clean non-critical and critical areas in dental offices. However, appropriate measures for their management are not adopted. It is necessary to implement educational strategies to improve the use and management of disinfectants in dental practice.

Arrays of digital data with valid goals and objectives of the study with a retrospective depth were subjected to statistical processing using correlation analysis. The cross-sectional analysis covered data on a variety of studied factors (the number of farm animals in households ranked by species composition of livestock, age groups and the number of heads, crop areas ranked by their size, the proportion of farms with or without their own hired workers, the presence of fishing activities, volumes of field and sown areas, as well as the numerical expression of comparable indicators in intersectoral relationships, including: per farm, per 100 capita, per horse, horses and cows per farm, etc.). The factors that influenced the organizational foundations of the leading branches of peasant production are analyzed. The question is raised about the nature of changes in the number and sex and age structure of the herd of the peasant economy during the years of the New Economic Policy. Particular attention is paid to the issues of the qualitative state of the livestock and changes in the repair base of livestock breeding. The dependence of the livestock of a peasant household on the size of the crop, the availability of workers and meadow areas has been revealed. At the same time, it is noted that the completion of the restoration processes in animal husbandry did not lead to qualitative changes in the economic structure of the northern village, the basis of which was a small parcel closed within the framework of subsistence production. The patterns identified by the authors can serve as an incentive for a further study of applied sectors of the naСаблин tional economy in the European North of Russia (development of the processing industry, trade, fodder production, transport networks, light industry, animal science, veterinary medicine, etc.).

The article aims to analyze the concept of an educational game in two philosophical concepts – phenomenology and philosophical hermeneutics. This approach is promising. It allows addressing the original meanings of the game, conducting a categorical analysis, and formulating a theoretical foundation and a methodological platform for the process of introducing game practices in education. This is relevant because, despite the numerous practices of using the game in education, the pedagogical and psychological justification of the game as a special method, a common semantic field regarding the concept of the game has not yet been formed. The ambiguity and instability of the term “game” today creates a situation of uncertainty in its use, and each time we need to redefine it for implementation into practice. To reach this aim, the authors use the works of Eugen Fink and deduce the main contradiction between the ontology of the game as the fundamental basis of human existence and the game as an educational practice. The game in its ontology takes place in “free time”, it has no purpose and is carefree, while educational practice always has a purpose. As an example of solving this contradiction, the authors refer to the works of Piero Bertolini. He proclaims the need to return to the real game. The teacher should leave the student alone with the game, give him/her freedom, realizing that the game itself is already part of learning. The game is a phenomenological method that allows the player to meet with the authentic and discover the realm of the “possible”. From this understanding of the game follows the problem of interpreting its meaning. As a source for this analysis, the authors use the phenomenological hermeneutics of Hans-Georg Gadamer. Based on the interpretation of hermeneutics, we cannot find objective meaning when interpreting games, but we are aware of our own subjectivity, the irreducibility of our own subjectivity in any act of interpretation. Moreover, this reasoning applies both to players inside the game who interpret game phenomena and actions of other players, and to a possible external observer of the game. The task of the interpreter in the case of a game as an educational event is to determine the factors that determine one’s own horizon of interpretation. The result of the review was the designation of another problem in understanding the game as an educational practice – the impossibility of its unambiguous interpretation, which also contradicts the external goal-setting of pedagogical methods. The solution of these two problems, according to the authors, is a promising task for subsequent research.

The study of personality is a cross-cutting direction of research in forensic science. One of the most effective methods for studying personality is the analysis of biographical information. Oral speech is of particular importance in the production of investigative actions that have a communicative aspect, such as interrogation, confrontation and presentation for identification on the basis of voice and speech. Signs of speech are individual, which determines their forensic significance. The aim of the work is to consider the possibilities of forensic research of personality through psychological analysis of oral speech and the biographical method. The main research methods were the biographical method of studying personality and the method of analyzing oral speech. The features of a typical speech model of participants in investigative actions belonging to various psychological types were analyzed. In recent decades, a new integrative field of scientific knowledge, the forensic doctrine of speech, has been actively formed in world forensic science at the intersection of psychology and linguistics. This line of research is based on the premise that a person’s oral speech is the richest source of information about a wide variety of features that characterize the speaker. Information about these features is established on the basis of an analysis of vocabulary, syntax, accent, and many other features of oral speech. Participating in the process of trace formation, reflection of events, recorded oral speech becomes a carrier of forensically significant information necessary for the detection and disclosure of crimes. The interrelation of the personality’s biography with the elements of the structure of oral speech is determined. For example, some structural elements of oral speech (content) reflect individual symbols and personally significant information in speech, which is closely related to the psychological data and social status of the individual (education and professional activity). The authors note a tendency in the analysis of speech behavior – the use of a typological approach, which makes it possible to individualize tactics in the production of investigative actions. The characteristics of a typical speech model of ten psychological types of participants in investigative actions are considered. The integration of psychological research methods into forensics also gives rise to a number of problems, such as the choice of the optimal personality typology, the need to develop a unified methodology for the psychological analysis of oral speech and the availability of specialists capable of analyzing speech on the basis of a special technical base.

The development of software tools is critical to meeting the changing needs of the wind and solar resource generation industries. By identifying some of the limitations of existing systems, such as fragmentation in data query and plant management, as well as a lack of data resource management. In response to these issues, it is proposed to use a hybrid deep network model for simulation data to develop a management platform for wind and solar resource observation data. High-quality real-time measurement data and standardized data processing can be collected stably using these tools, which can significantly improve the development efficiency of landscape resource power generation projects and save development costs.
Policing the In/Exclusion of Social Marginality: The Preventive Regulation of Public Space in Urban Switzerland
Authors: Piñeiro Esteban , Pasche Nathalie , Locher Nora
Published: May 2023

Urban spaces are always contested and, as such, permeated by processes of inclusion and exclusion. Since the 2000s, new types of governmental public order services have been established in Switzerland specialized in dealing with socially marginalized individuals, groups, or areas. Without having police powers, they proceed with socio‐communicative methods typical in outreach social work. Based on our ethnographic research and drawing on Foucault‐inspired governmentality studies we elucidate the socio‐preventive risk management of two types of order services: While the welfare type aims to protect public spaces of attractive urban centers from social marginality, the neighborhood watch type is concerned with improving the coexistence of residents of marginalized housing developments. As the former wants to keep socio‐spatial in/exclusion of social marginality in motion and prevent its fixation in certain places, the latter works towards the inclusive socio‐spatial entrenchment of residents in segregated housing developments. Both dynamics—inclusion and exclusion—are closely intertwined and utilized for the governance of public spaces. The “inclusive city” should not be celebrated as a dull ideal and must be confronted with its own socio‐spatial mechanisms of exclusion.
Driving Towards Car-Independent Neighborhoods in Europe: A Typology and Systematic Literature Review

Car-independent neighborhoods can be seen as a planning strategy for overcoming car dependency and achieving urban sustainability goals. This implies a structural and psychological car independency of people, which manifests itself into positive attitudes and perceptions towards sustainable mobility, acceptance of corresponding measures, and a shift from private cars to active transport, public transport, and sharing modes. Despite their relevance, knowledge regarding the actual implications of the various existing strategies remains scarce. This gap is addressed in this literature review, which aims to: (a) identify types of implemented car-independent neighborhood policies; (b) explore their rationales, main characteristics, and implications for mobility behavior, psychological factors, perceptions, and acceptance; and (c) investigate how they have been evaluated. Existing implementations in Europe can be divided into four types: car-independent central areas, residential developments, citywide implementations, and temporary interventions, which differ in their rationales and scope. Overall, little research was found on this topic, with most studies focusing on newly built residential developments, compared to the other types. There is evidence of positive impacts on sustainable mobility behavior in the relevant use cases. However, it is often unclear whether this is a causality or correlation due to the absence of comprehensive (longitudinal) evaluations. Less is known regarding the implications of implementations for psychological factors and perceptions and their interplay with mobility behavior. For future research, it is recommended to evaluate other types of car-independent interventions beyond newly built developments through long-term observation of attitudinal and behavioral changes.
