Immanent obligations of response: articulating everyday response-abilities through care
Authors: Baan Hofman Lydia
Published: February 2023

The geological epoch of the Anthropocene provokes the reconceptualization of responsibility as response-ability. Going beyond bounded individualism and human exceptionalism, this notion emphasizes the constitutive relationality of heterogeneous more than human beings that allows for response. Feminist STS scholar and biologist Donna Haraway has developed response-ability primarily as an epistemological notion with ontological and ethico-political aspects, crucial in the context of professional technoscientific research practices. This article articulates nonprofessional, everyday response-abilities. Thinking with María Puig de la Bellacasa's, Isabelle Stengers', and Annemarie Mol's conceptions of care, I relay response-ability as a combination of forms of care that are worldmaking, an etho-ecological practice, and experimental in nature. Everyday response-abilities are something we are all engaged in yet need cultivation in times of crises through careful tinkering.
Statistical precursor signals for Dansgaard-Oeschger cooling transitions
Authors: Mitsui Takahito , Boers Niklas
Published: February 2023

Given the likely bistability of the Atlantic Meridional Overturning Circulation (AMOC) and its recently inferred weakening, it is important to investigate the capability of identifying robust precursor signals for a possible future AMOC collapse as well as its collapses in the past. Dansgaard-Oeschger (DO) events, manifested most clearly as abrupt Northern-Atlantic temperature jumps during glacial conditions, likely reflect past switches between strong and weak AMOC modes. In general, the variance and the autocorrelation with a small lag increase in a system approaching a co-dimension one bifurcation point. Some previous studies find such statistical precursor signals for the DO warming transitions associated with a strengthening AMOC. On the other hand, statistical precursor signals for the abrupt DO cooling transitions, presumably associated with AMOC transitions from the strong to the weak mode, have not been identified. Here we identify robust and statistically significant precursor signals for several DO cooling transitions in Greenland ice core records. The important source of the statistical precursor signals stems from so-called rebound event, humps in the temperature observed at the end of interstadial, some decades to centuries prior to the transition. We propose several dynamical mechanisms that give rise to such rebound events and statistical precursor signals.
The Social Determinants of Resilience: A Conceptual Framework to Integrate Psychological and Policy Research

Published: February 2023

The psychological study of resilience has increasingly underscored the need for children and families to access material and psychological resources to positively adapt to significant stress. Redistributive policies—policies that downwardly reallocate society’s social and economic resources—can offer economically disadvantaged families sustained access to these resources and mitigate the harmful impacts of adversity. This conceptual paper builds upon and integrates insights from psychological and policy research to develop a unifying multilevel resilience framework, which we call the Social Determinants of Resilience. We examine four U.S. redistributive policies that have been extensively studied for their effects on child and family outcomes as case studies: 1) Medicaid expansion; 2) the Earned Income Tax Credit; 3) childcare subsidies; and 4) Temporary Assistance for Needy Families. Informed by a scoping review of each policy, we propose that redistributive policies promote children’s resilience through three mechanisms, by: 1) increasing families’ resource and service access; 2) reducing family stress; and 3) enhancing adaptive cognitions, emotions, behaviors, and interpersonal processes that protect against the development of psychopathology and promote positive mental health outcomes. Highlighting current evidence for these resilience mechanisms as well as gaps in knowledge, we conclude by setting a multidisciplinary research agenda that can leverage this conceptual framework to advance the science on how redistributive policies enable children and families to thrive.
Teacher Beliefs about Disadvantaged Students in the global South: Theory and Evidence
Authors: Kurian Nomisha , Gruijters Rob J.
Published: February 2023

Low learning outcomes, especially among poor and marginalized students, are a pervasive problem in many low- and middle-income countries. Negative teacher beliefs and expectations may contribute to low learning outcomes among the poor, especially if they are reflected in classroom practices and interactions. Studies from various Southern contexts have shown that students from poor and marginalized backgrounds are more likely to be subject to stereotypical and deficit-oriented teacher beliefs, but the evidence is scattered and disconnected. This study therefore systematically reviews the empirical literature on teacher beliefs and their implications for the educational outcomes of disadvantaged students in the global South. We primarily focus on studies using a qualitative sociological approach, to complement an existing review that looks on the quantitative and econometric literature. Based on the findings, we develop a conceptual framework that identifies the structural and cultural determinants of teacher beliefs and the various mechanisms that link them to diminished wellbeing and educational achievement for disadvantaged students. The 55 empirical studies included in our review poignantly illustrate the degree of injustice and discrimination inflicted on the children of the poor as they navigate education systems around the world. We also highlight examples of positive teacher beliefs and practices, however, and discuss promising avenues for further research. Finally, we argue that any policy interventions aimed at changing teacher beliefs should be based on a contextualized understanding of these beliefs and their effects on learner engagement and achievement.
‘Out of time’: Constructing teacher professionality as a perpetual project on the eTwinning digital platform
Authors: Lewis Steven , Decuypere Mathias
Published: February 2023

This paper seeks to understand what digital schooling platforms do to teacher professionality; that is, the combination of professional knowledge, discretion and responsibility that enables a teacher to be professional. Specifically, we explore how the European Commission’s (EC) teacher professional learning platform eTwinning promotes a projectified (i.e., project-focused) and platformed (i.e., largely occurring on digital platforms) version of teacher professionality. Informed by recent thinking around ‘projectification’; that is, the ability of the project form to shape work practices, as well as the topological nature of timespace within a project, we argue that projectified teacher learning and professionality are now constituted through platform dynamics as a perpetual project-initself. As such, the projectified teacher is left simultaneously in-time (i.e., within the bounds of the project timespace) and out-of-time (i.e., out of possibilities of progress that can exist outside of the project), and thus faces the insuperable task of never-ending self-improvement through and as the project form (teacher-as-project).
The role of platforms in diffracting education professionalities
Authors: Clutterbuck Jennifer
Published: February 2023

This paper examines the effect of data management platforms on professional educators. The ways in which platforms re-shape new professional patterns of school leaders and education bureaucrats is presented through the data management platform, OneSchool. OneSchool is used across 1,258 public schools in Queensland, Australia. Empirical data were gathered from interviews with senior bureaucrats, policy officers, and school leaders from Queensland’s public schooling system. Thematic analysis identified shifts in educational practitioners’ professional roles as they performed their tasks through OneSchool. Analysis of traditional school roles and tasks on the one hand and demands of online security and information privacy legislations on the other were brought together in an access assemblage. Access was provided by the authorized allocation of ‘roles’ embedded into the platform’s technical code. A dual perspective of the development and use of the OneSchool platform is used to show how educational behaviors, skills and qualities are mutually constitutive of platformized professionalities. To make sense of these platformized professionalities, a diffraction lens is employed, derived from Barad’s (2007) considerations within new feminist materialism and physics. Recalling Foucault’s (1983) adage that everything is dangerous rather than bad, this paper provides insight into the positive and negative ways platforms disrupt and re-shape educational practitioners and their professionalities.

Published: February 2023

The Soil and Water Assessment Tool (SWAT), a semi-distributed hydrological model, has been used for the Seti-Gandaki River Basin (SGRB) to simulate streamflow. Further, SWAT was assessed to study water balance of the basin. This study primarily focuses on different features of hydrological modeling like multi-site calibration and validation of the streamflow with a view to check the reliability of the model in the high precipitation basin of Nepal. The statistics performance of the model is evaluated using various statistical test like Nash-Sutcliffe, RMSE, and Kling Gupta Efficiency (KGE). Moreover, the study used various statistical parameters like Nash-Sutcliffe efficiency (NSE), Percentage Bias (PBIAS), Coefficient of Variation (R2), ratio of the root mean square error to the standard deviation of measures data (RSR), and Kling Gupta Efficiency (KGE) to evaluate the performance of the model and carryout0.93(0.89), -0.04(-21.87), 0.95(0.94), 0.26(0.34), and 0.85(0.76), respectively, for calibration (and validation) at Damauli station. The mean annual flow and annual precipitation at SGRB was observed to be 209 m3/s and 2866 mm, respectively. About 20% of annual precipitation seems to be lost as evapotranspiration. The statistics results showed that the model performed better for daily and monthly periods. Overall, the versatility and reliability of SWAT is an appropriate hydrological modeling tool for water resources over the study region. The output of the study can be helpful for the planning and management of water resources in high precipitation basins.

Looking Back inKewekapawetan: Return After the Flood. Research, Remembrance and Reclamation of a Hydro Story
Authors: Huberman Isabella
Published: February 2023

This essay analyses Jennifer Dysart’s 2014 documentary film Kewekapawetan: Return After the Flood, which tells the past and present-day story of the Northern Manitoba Ithinew (Cree) community South Indian Lake and its entanglement with Manitoba Hydro. Dysart documents the history of colonial hydro policy by showcasing rare archival footage from the late 1960s and reclaims this material for the community she has roots in. At the same time, she records her search to learn about her father’s life and her efforts to reconnect with family by spending time on the land. Discussion between author and filmmaker throughout the research and writing process engages “visiting” as a methodology for studying Indigenous narrative arts. Ultimately, Dysart’s visual storytelling is a critical site of knowledge-making about the dislocation caused by large-scale resource extraction that foregrounds reconnection to family, community and land.

Published: February 2023

In “Pinery Road & Concession 11”, writer, academic and musician Leanne Betasamosake Simpson reflects on the chapter of the same name in Dionne Brand’s A Map to the Door of No Return. By physically traveling to the same corner in rural Ontario that Brand’s car broke down two decades earlier, Simpson considers place, belonging, diaspora, property, and foreclosure in her own Michi Saagiig Nishnaabeg homeland. Simpson’s companion on part of the journey is an 80 year old Black Ash Basket which she repatriates to Curve Lake First Nation on the way. What follows is the text of the piece originally presented at the Map to the Door At 20 gathering. Simpson presented the piece over looped time lapse photography of the journey and surveillance footage of the intersection of Pinery Road & Concession 11. Simpson’s sister, Ansley Simpson provided a soundscape for the piece, repurposed from Leanne’s track “Solidification” (Noopiming Sessions, Giizhiwe Music, 2021). “Pinery Road & Concession 11” is an honour song to Brand’s constellation of thought that has traveled the world, and back to the Burnt River, near Kinmount, Ontario.

The major drawback of a dioecious spine gourd (Momordica dioica Roxb.) is distinguishing whether the plant is male or female at an earlier development stage. An investigation was aimed to eliminate aforesaid limitation by identifying and validating sex linked molecular marker. Twenty six male and female genotypes of each sex were screened with 12 specific SSR primers. Only two SSR primers, MdSSR 5 (MADS-box gene of spine gourd) and CMbSSR 6 (MADS-box gene of cucumber) showed amplification and polymorphism in female genotypes only. These specific female linked markers manifest existent of non-epigenetic factors entailed in gender development in the spine gourd.

Additive main effects and multiplicative interaction (AMMI) model is most widely used to analyze genotype x environment interactions (GEI) wherein interaction effects of location is masked by year effect. Hence, presently available models are not able to estimate interaction effects of genotype x location (GLI) and genotype x year (GYI) separately. Moreover, genotype ranking differs as number of years of evaluation vary making selection of genotype for target location difficult. In the present study, a novel stability model i.e., Higher-order-AMMI (HO-AMMI) analysis which can calculate GLI without the confounding effect of GYI and GLYI has been proposed. GEI of AMMI model and all 2-way interactions of HO-AMMI model follow χ2 distribution, whereas 3-way interaction (GLYI) of HO-AMMI follow noncentral χ2 distribution. With increase in number of years of evaluation contribution of GLI towards total variation increased whereas in AMMI model contribution of GEI towards total variation decreased. Variation explained by multiplicative components is higher in HO-AMMI compared to AMMI model. Genotypes were ranked using GL, GY and GL+GY+GLY interactions of HO-AMMI and GEI of AMMI for stability and yield and compared their ranks with field ranking. Correlation and linear regression analysis have indicated high association of GLI (HO-AMMI) with field ranking with high R2 values. Further, HO-AMMI model was able to remove the confounding effect of GYI and GLYI on GLI for accurate identification of genotype for target location irrespective of number of years of evaluation. Hence, HO-AMMI model can be used under multi-environment trials(MET) for selecting genotypes efficiently.

Soil phosphorus (P) deficiency is one of the major challenges for rice cultivation. The present study was carried out under low soil P condition (available P, < 2 kg ha-1) to study the genetic variability, correlation, path and principal component analysis (PCA) in a set of 40 introgression lines derived from Samba Mahsuri (Oryza sativa ssp. indica) × Oryza rufipogon. High genotypic coefficient of variation and phenotypic coefficient of variation was recorded for productive tillers (PT), seed weight (SW), and grain yield (GY). High heritability coupled with high genetic advance was recorded for plant height (PH), PT, SW, number of spikelets/panicle (SPP), spikelet fertility, and GY. Correlation analysis revealed that grain yield had a significant positive association with PH, PT, panicle length, SPP, and SW. Regression analysis revealed that the grain yield was mainly influenced by PT and SW. This was confirmed by path analysis, wherein PT and SW exerted the highest direct positive effect on grain yield. The PCA revealed that the first two PCs contribute to maximum variability, which together accounted for 60% of the total variability. The traits PT and SW contributed the maximum to load/variance the total variability. Thus, the selection of introgression lines with a greater number of PT and higher SW would be the most appropriate strategy for yield improvement under low soil P condition in rice. Cluster analysis grouped introgression lines along with checks into three clusters. Overall, the study revealed the pattern genetic variability for low P tolerance in the introgression lines. This further helps in designing appropriate breeding strategies for the improvement of rice cultivars for low P tolerance.

A set of 27 bread wheat varieties from Ethiopia was assessed for physico-chemical quality characteristics of grain under lowland. Varieties differed significantly for all the studied quality traits. Grain weight, diameter and hardness of the grain were positively associated with starch content and grain yield but negatively associated with protein content. D2 and principal component analysis grouped 27 genotypes in to four diverse genotypic clusters accounting for 89.17% of the total variation. The PC1 accounted for 46.41% of the variation with major contribution by total wet gluten, dry gluten, kernel diameter and red kernel, while PC2 accounted for 25.06% of the variation with major contribution by gluten index, kernel weight, water bound wet gluten, Zeleny index and grain yield. Based on the genetic diversity for physico- chemical characters and correlations, the appropriate varieties can be used for different food products and utilized as parents in breeding programme for improving quality.

Intron Polymorphism (IP) markers were used to unravel the genetic variation and relationship among 26 genotypes representing six cultivated Brassica species described in the classical U triangle. One hundred and twenty-five Arabidopsis thaliana-derived IP markers were assayed and 90 to 100% cross-transferability was observed in the six Brassica species suggesting that IP markers were highly conserved during the evolution of different Brassica species. The number of alleles observed in species at each locus ranged from one to ten with an average of 2.89 alleles per primer pair and there was no consensus between the number of alleles amplified in diploid and tetraploid species. The size range of amplified alleles was 120-1250bp, which reflects enormous deletions/insertions in different alleles. In B. juncea, 100% cross-transferability had been obtained and 121 IP markers resulted in polymorphic amplicons with PIC value of 0.04 to 0.48. The dendrogram divided all the 26 genotypes into two groups composed of B. napus/B. rapa/B. oleracea and B. carinata/B. nigra/B. juncea. A-genome present in B. juncea and B. napus/B. rapa seems distinct from each other and hence provides a great opportunity for generating diversity through resynthesizing amphidiploids from different available sources of Agenome. The A and B genomes are more similar in comparison to C genome in tetra-diploid species.The evolutionary relationship established between various Brassica species would support in formulating suitable breeding approaches for widening the genetic base of Brassica amphidiploids by exploiting the genetic diversity found in diploid progenitor gene pools.

This article examines the issues of developing mathematical models for optimizing the parameters of the thermal action on the technical systems. The authors set the task of determining the optimal parameters of sources of temperature field disturbance in the technical system under the appropriate restrictions. Considering the technical characteristics of the means that ensure the process of thermal action on the material, and the peculiarities of the technological process, appropriate restrictions on the temperature field and its components are set. Checking the limits of the temperature field requires multiple calculations, which reduce thermal damage to parts of the material. To automate the objective function, it is possible to use grid processors, which, due to the use of specialized functional blocks, solve a huge number of boundary problems with computers almost instantly. Because to the selection of solutions of boundary value problems, this will allow to find optimal values of technical parameters, and therefore to increase the accuracy of the simulated process. The research of this article refers to the section on mathematical modeling and optimization of systems with distributed parameters. For mathematical modeling of these systems, boundary value problems of differential equations with partial derivatives are used. The authors present applied optimization mathematical models for controlling the distribution of the temperature field and thermal stresses in the material, minimizing its damaged parts. The last them is based on the differential criterion for evaluating the temperature of irradiation and can be used to optimize many technical, biotechnological and economic systems. A detailed analysis of the specific features of applied optimization mathematical models will allow to increase the accuracy of the development of numerical methods and hardware and software tools for calculating and optimizing the parameters of simulated systems.

This paper presents the results of research on solving excess problems by the stoichiometric method of calculation, this approach is rational, simple, and easily adapted to the school program. If a student correctly wrote the equation of reactions, compiled an algorithm of tasks, and solved one task completely, then with a high degree of certainty it can be stated that he/she is able to solve the tasks of the suggested types. Thus, the number of analyzed problems increases and an opportunity arises in the high grades to converge in space and time problems of different types, and convergence in space and time makes it possible to notice the similarity and difference between different types of problems faster. The learning process becomes more effective as a result of constant and more intensive use of such mental actions as comparison, analysis, synthesis, classification, and abstraction. The system under discussion forces the student to refer more often to the condition of the problem and to comprehend it more deeply, using the table one can set the algorithm of solving a problem or on the known algorithm to make the condition of the problem and using this table with proper decoding of commands (operators) and translation of algorithms into one of the machine languages, one can make a program for programmable microcalculator or computer.

Published: February 2023

This work is devoted to the study of the extraction process of protein from soybean meal with subcritical water. The aim of the study is to determine the influence of parameters (temperature: , extraction duration: ( ), hydromodulus: ) of the subcritical water extraction process on the protein content in the dry matter of soybean meal extract and their rational values. To determine the rational parameters of the extraction process, an empirical research method was applied using an orthogonal compositional plan of the 2-nd order for a fractional-factorial experiment . Samples of extracts were obtained on a laboratory setup based on a high pressure reactor. In the obtained samples, the total protein content was determined by the method of catalytic oxidation with chemiluminescent detection. On the basis of the obtained results, a quadratic interpolation model was constructed that relates the total protein content in the dry matter of the extract with the extraction parameters. The analysis of the constructed model made it possible to establish the optimal extraction parameters: temperature , extraction duration . The yield of protein to the dry matter of the extract at optimal values of temperature and duration of the process monotonically increases with an increase in the hydromodulus and reaches a maximum at the hydromodulus . The results obtained can be used to improve the technology for obtaining soy protein concentrate and isolate using the subcritical water extraction method. Due to the environmental friendliness of this extraction technology, the resulting extracts can be directly used to improve the nutritional value of various food products.
OPTIMIZATION OF CHARGE / DISCHARGE TIME OF ACTIVE FILTER CAPACITORS DURING VOLTAGE FLUCTUATIONS
Authors: BURBELO Mykhailo , LEBED Denys , LESHCHENKO Oleksandr ,   Vinnytsia National Technical University
Published: February 2023

A voltage regulator on capacitors has been developed for the control circuit of a parallel active filter based on dq-theory with a block of sliding averaging current in the current control circuit i_d. It contains a delay unit, a digital low-pass filter of the first order FIR or IIR (depending on the variant of the considered scheme) and the unit “sgn”, which stabilizes the output signal. The voltage control circuit on the capacitor can be implemented entirely in digital signal processing and used instead of the analog PID controller, which is much more effective if you need to adapt the circuit to the load mode. Most analog filters suffer from phase distortion when signals at different frequencies are delayed by different amounts. Although it is still present in digital IIR filters. FIR filters are usually designed as a “linear phase”, which means that the filter has no phase distortion. Phase distortions occur due to the fact that signals of different frequencies are delayed differently when crossing the filter. For IIR filters, it is necessary to enter an additional factor that will regulate the group delay, during which the filter will delay the signal of a certain frequency. If you do the same for the FIR filter, you will see a straight horizontal line, which means that all signals are delayed by the same amount, which is good and will provide better signal quality. The unit “sgn” does not affect the process of maintaining the voltage on the capacitors and the speed of transients, its role is to enhance the compensatory capacity of the voltage regulator by filtering the digital signal. The selected filter, by automatically stabilizing the voltage on the capacitor provides a stable charge / discharge process of the capacitor and a high level of compensation of higher harmonics without significant additional generation of active power in the network. When used in the context of real-time analog systems, the digital filter sometimes has a problematic delay (input-output time difference) due to analog-to-digital and digital-to-analog conversion and smoothing. It is shown that by optimizing the charge / discharge time of the capacitor of the power active filter it is possible to achieve the minimum duration of the transient process with the minimum values of harmonic distortions.

In 2020, more than 18 million cases of cancer were recorded worldwide, amongst which hepatic cancer ranked sixth. Colorectal cancer, which ranks third, gives rise to secondary liver tumors. Several options are available to treat this disease. Currently, one of the leading strategies is liver resection, which can be done either standalone or in combination with radiotherapy and chemotherapy. The history of laparoscopic liver resection (LLR) dates back to 1991, and has been evolving continuously. However, there are certain challenges preventing this: the lack of equipments in hospitals and their cost, and as a result, the lack of skilled surgeons. This review will cover LLR in various malignancies, as well as its comparison with the open resection method (efficacy, safety, results, costs).

Silicone lymphadenopathy is a rare complication in breast implant patients caused by the presence of silicone particles in the lymph nodes with the development of specific granulomatous inflammation. Most often, it occurs against the background of a violation of the integrity of the silicone implant capsule and the spread of silicone into the surrounding tissues. Due to the rarity of this pathology, there are no statistical data on the prevalence of this disease. The literature review presents the data of foreign authors on the clinical picture, diagnosis and treatment of this pathology. Silicon lymphadenopathy is a diagnosis of exclusion, primarily of malignant neoplasms of the breast, since the clinical picture is similar. Silicone lymphadenopathy should be included in the differential diagnosis in patients with enlarged lymph nodes who have previously undergone plastic or oncoplastic surgery using silicone endoprostheses.

By comparing the advantages and disadvantages of the existing support, an innovative optimization design is proposed, and the mechanical structure of the support is analyzed by ANASYS to check the rationality of the design. Saving construction materials and reducing construction costs provide a basis for the reasonable design of photovoltaic power station supports, and also provide a reference for the structural design of fixed and adjustable supports.
Untangling the Role of Tau in Huntington’s Disease Pathology
Authors: Salem Shireen , Cicchetti Francesca
Published: February 2023

There is increasing evidence for the presence of pathological forms of tau in tissues of both Huntington’s disease (HD) patients and animal models of this condition. While cumulative studies of the past decade have led to the proposition that this disorder could also be considered a tauopathy, the implications of tau in cellular toxicity and consequent behavioral impairments are largely unknown. In fact, recent animal work has challenged the contributory role of tau in HD pathogenesis/pathophysiology. This review presents the supporting and opposing arguments for the involvement of tau in HD, highlighting the discrepancies that have emerged. Reflecting on what is known in other tauopathies, the putative mechanisms through which tau could initiate and/or contribute to pathology are discussed, shedding light on the future research directions that could be considered to confirm, or rule out, the clinical relevance of tau in HD.

Intelligent answering technology, which enables computers to solve problems automatically, is often used to develop tutorial systems, and has a wide range of application prospects. However, due to the lack of linguistic analysis and understanding methods, there are few researches on intelligent algorithms for solving kinematics problems. Developing such an algorithm is challenging, because solving kinematics problems is a complex task that includes text understanding, problem analysis, and automatic solution. To understand all these complexities involved in kinematics problems requires background knowledge. And only when an automatic solver contains a powerful internal knowledge representation system can it perform these tasks. We, thus, develop KinRob, an tutorial system for solving kinematics problems by combining neural network and ontology. Firstly, we propose an ontology for KinRob, which defines the knowledge of kinematics, and can help the robot understand a kinematics problem. Secondly, to match the text in natural language with the ontology, we propose a novel tagging scheme based on the kinematic problem understanding model in named entity recognition (NER). Finally, extensive experiments are conducted, and the experimental results show that the performance of the proposed method on a dataset of kinematic problems from authoritative sources better than the baseline algorithms.

BACKGROUND:

Smoking is one of the most popular risk factors provoking bladder cancer (BC). This research intended to estimate cigarette smoking effect involving PAF signs between smoking patients with BC and non-smoking patients with same diagnosis to define relations with pathological characteristics and their prognosis on zero-relapse and disease-associated recovery.

METHODS:

Two groups of smokers ( n = 54) and non-smokers ( n = 62) were selected. Both cohorts of patients had BC. They were evaluated utilizing NGS on 9 cancer-related genes and confirmed through the Sanger DNA sequencing and histopathological tests based on H&E staining. The factor of smoking and impact of PAF development by ELISA assay and PAF-R manifestation in terms of immunochemical evaluation on BC areas comparing to a control group ( n = 30) was examined involving healthy contributors, including the use of well-designed statistical trials.

RESULTS:

The multivariate evaluation showed considerable rise in mutation patterns related to smoking among BC patients (group 3), increase in PAF development (***P<0.001) and vivid signs of PAF-R contrasted to non-smokers with BC (group 2) and control group (group 1). All the identified biological changes (gains/losses) were recorded at the same locations in both groups. Patients from group 3 held 3-4 various mutations, while patients from group 2 held 1-3 various mutations. Mutations were not identified in 30 respondents from control group. The most repeated mutations were identified in 3 of 9 examined genes, namely TP53, PIK3CA and PTEN, with highest rates of increase in Group 3. Moreover, histopathological tests revealed barely identifiable and abnormal traits in BC tissues, i.e. were without essential histopathological changes between groups 2 and 3.

CONCLUSION:

Smoking of cigarettes provokes PAF development due to urothelial inflammation and rise of mutations in 9 cancer-related genes. These are indicative factors of inducing BC.

Introduction. Alcoholism is still a pressing socio-medical problem in Russia that needs to be considered within the broader socio-economic context. Therefore, this study focuses on socio-economic indicators and their association with the incidence of alcoholism and alcoholic psychoses. Aim. To study the correlations of socio-economic indicators with the incidence (the number of new cases) of alcoholism and alcoholic psychoses in Russia, 1992-2020. Materials and methods. Correlation analysis was used to analyze the relationships between a set of socio-economic indicators, cases of alcoholism and alcoholic psychoses. Data analysis was conducted using the SPSS software package. Results. The incidence of alcoholic psychoses correlates with the Index of Economic Freedom (r= -0.427 | moderate association), Human Development Index (-0.629 | noticeable), unemployment rate (0.655 | noticeable), poverty level (0.482 | moderate). The incidence of alcoholism correlates with Gini coefficient (-0.595 | noticeable), Human Development Index (-0.975 | strong), unemployment rate (0.765 | high), poverty level (0.803 | high), price of vodka (0.769 | high). Public health expenditure in relation to GDP (%) does not correlate with the incidence of alcoholic psychoses and alcoholism. Conclusion. The results of the study showed significant associations with 6 out of 7 socio-economic indicators. This may indicate that the incidence of alcoholism and alcoholic psychoses is largely caused by the socio-economic situation.

This mixed-methods case study examines the emergency financial management legislation enacted in Michigan from 2009 to 2018 as an education policy for governance reform in three local school districts: Detroit, Highland Park, and Muskegon Heights. From its inception, the emergency financial manager law was an intervention strategy for local municipalities in financial emergencies. Still, in 2009 it was used to enable state takeovers of three local school districts experiencing financial emergencies. This study addresses the gap in the literature regarding the effectiveness of emergency management as an education policy in general and highlights its specific application to the three districts.
