Multi-ACCDOA: Localizing and Detecting Overlapping Sounds from the Same Class with Auxiliary Duplicating Permutation Invariant Training
Authors: Shimada Kazuki , Koyama Yuichiro , Takahashi Shusuke , Takahashi Naoya , Tsunoo Emiru , Mitsufuji Yuki
Published: March 2022

Sound event localization and detection (SELD) involves identifying the direction-of-arrival (DOA) and the event class. The SELD methods with a class-wise output format make the model predict activities of all sound event classes and corresponding locations. The class-wise methods can output activity-coupled Cartesian DOA (AC-CDOA) vectors, which enable us to solve a SELD task with a single target using a single network. However, there is still a challenge in detecting the same event class from multiple locations. To overcome this problem while maintaining the advantages of the class-wise format, we extended ACCDOA to a multi one and proposed auxiliary duplicating permutation invariant training (ADPIT). The multi-ACCDOA format (a class- and track-wise output format) enablesthe model to solve the cases with overlaps from the same class. The class-wise ADPIT scheme enables each track of the multi-ACCDOA format to learn with the same target as the single-ACCDOA format. In evaluations with the DCASE 2021 Task 3 dataset, the model trained with the multi-ACCDOA format and with the class-wise ADPIT detects overlapping events from the same class while maintain-ing its performance in the other cases. Also, the proposed method performed comparably to state-of-the-art SELD methods with fewer parameters.

Published: March 2022

Automotive radar provides reliable environmental perception in all-weather conditions with affordable cost, but it hardly supplies semantic and geometry information due to the sparsity of radar detection points. With the developmentof automotive radar technologies in recent years, instance segmentation becomes possible by using automotive radar. Its data contain contexts such as radar cross section and micro-Doppler effects, and sometimes can provide detection when the field of view is obscured. The outcome from instance segmentationcould be potentially used as the input of trackers for tracking targets. The existing methods often utilize a clustering based classification framework, which fits the need of realtime processing but has limited performance due to minimuminformation provided by sparse radar detection points. In this paper, we propose an efficient method based on clustering of estimated semantic information to achieve instance segmentation for the sparse radar detection points. In addition, we show that the performance of the proposed approach can be furtherenhanced by incorporating the visual multi-layer perceptron. The effectiveness of the proposed method is verified by experimental results on the popular RadarScenes dataset, achieving 89.53%mCov and 86.97% mAP0.5, which is the best comparing to other approaches in the literature. More significantly, the proposed algorithm consumes memory around 1MB, and the inferencetime is less than 40ms. These two criteria ensure the practicality of the proposed method in real-world systems.

How to refute anxieties of OCD using a template of ‘3’ and ‘1’
Authors: Hozez Yaniv
Published: March 2022

The objective of this paper is to demonstrate how to refute anxieties of OCD, using a method based on pure logic. Background: I had suffered from a severe case of Obsessive Compulsive Disorder (OCD). After almost 17 years of stubborn struggle accompanied with countless obediences to rituals, the disease finally began to weaken as I had been starting to vision the digits ‘3’ and ‘1’ in my mind for a few months before I had visioned, at a sudden, the digits ‘1’ and ‘0’ in my mind for long seconds, realizing that the OCD has contradicted itself, and thus, how to refute anxieties whose recurring pattern is utilized by OCD, by a specific template. Methodology: OCD makes you believe that if you do not perform a compulsive ritual, then something bad will occur, or that you should perform a compulsive ritual for something bad not to occur. OCD is faster from those who suffer from it. As a result, and because a person needs time to consider whether an anxiety is correct or not, OCD precedes him, so he would instantly go into a state of anxiety.

Published: March 2022

Heart Rate Variability (HRV) is a putative biological mechanism and marker of depression, which can be measured with low costs and in naturalistic settings. Therefore, applying machine learning (ML) on HRV data, could be a promising path to predict and monitor depressive symptoms in patient populations. A sample of 2629 participants completed self-administered HRV resting state recordings with a wearable device as part of a therapist-supported digital mental health intervention for anxiety and depression. Findings revealed that higher baseline Patient Health Questionaire-9 (PHQ-9) scores were associated with significantly higher heart rate (r = 0.14, p <0.001) and lower root mean error of successive differences (r = -0.09, p <0.001). We contrasted multiple machine learning algorithms with repeated 5-fold cross validation on a separate training set of 1830 to classify participants as having moderate depressive symptoms, indexed as a PHQ-9 score of 10 or greater. The best performing algorithm reached an area under the receiver operating characteristic score (ROC AUC) of 0.56 (p = 0.003) on the previously unseen test set, which was less than expected. Sensitivity analyses showed that model performance was not substantially impacted by variations in PHQ cut-offs or data quality. In conclusion, using wearable-derived HRV for cross-sectional prediction of depressive symptoms is challenging in settings with myriad real-world, day-to-day sources of variation.
Propagation of Societal Gender Inequality by Internet Search Algorithms
Authors: Vlasceanu Madalina , Amodio David
Published: March 2022

Humans increasingly rely on artificial intelligence (AI) for efficient and objective decision making in virtually all sectors of society. Yet there is increasing concern that algorithms used by modern AI systems produce discriminatory outputs, presumably because they are trained on data in which societal biases are embedded. As a consequence, their use by human decision makers may result in the propagation, rather than reduction, of existing disparities. To assess this hypothesis empirically, we assessed the relation between societal gender inequality and algorithmic search output and then examined the effect of this output on human decision making. First, in two multinational samples (N=37, 52 countries), we found that greater national-level gender inequality was associated with more male-dominated Google image search results for the gender-neutral keyword person (in a nation’s dominant language), revealing a link between societal-level disparities and algorithmic bias. Next, in a series of experiments with human participants (N=395), we demonstrated that the gender disparity associated with high- vs. low-inequality algorithmic outputs guided the formation of gender-biased prototypes and influenced hiring decisions. These findings support the hypothesis that societal-level gender inequality is recapitulated in internet search algorithms, which in turn influence human decision makers to act in ways that reinforce these disparities.
Glimpses on Emerging Alternative Living and Care Arrangements for Elderly People in Nepal
Authors: Speck Sarah , Muller-Boker Ulrike
Published: March 2022

This paper explores emerging alternative living and care arrangements for elderly people beyond the family, in Nepal. Family-based care and support for the old in Nepal are no longer guaranteed. Elderly people are abandoned or neglected mainly due to massive outmigration of the young and demographic change. As are sult, demand for place in old age homes and care centers is rapidly increasing. Exploratory visits at six different institutions, expert interviews and informal conversations with elderly residents and their relatives offered a first-hand insight into these institutions. Equipped with only the most basic facilities, lack of trained personnel, and major financial reliance on donations, old age homes that receive mainly destitute people, are overstretched and have long waiting lists. This exploratory study concludes that emerging alternative elderly living and care arrangements are much needed in Nepal and that the current facilities are rudimentary. However, the negative picture of old age homes painted by the public media is inaccurate. The study found that elderly people and close relatives are grateful for new options. The increase in the number of such institutions indicates a transformation in attitudes towards intergenerational relations and elderly support options beyond the traditional extended family.

Published: March 2022

A jabuticaba (Myrciaria ssp) é bem conhecida por possuir em sua casca compostos fenólicos com alta atividade antioxidante. Assim, este estudo objetivou avaliar efeitos antioxidantes em fígado e cérebro e antimutagênicos na medula óssea de camundongos Swiss machos com o extrato aquoso de jabuticaba (MYR) e como agente indutor de danos mutagênicos a ciclofosfamida (CPA). Foram analisados 4 grupos (N = 6): Controle (C), CPA (25 mg.kg-1), Extrato aquoso de jabuticaba + CPA (MYR + CPA) e Extrato aquoso de jabuticaba (MYR). Através do teste do micronúcleo em células de medula óssea avaliou-se a frequência de micronúcleos em eritrócitos policromáticos para a atividade antimutagênica/mutagênica. Os parâmetros bioquímicos avaliados foram: Superóxido dismutase (SOD), Catalase (CAT), Glutationa-S-transferase (GST), Glutationa reduzida (GSH), Ácido Ascórbico (VIT C) e Carbonil. Os resultados obtidos mostraram que o extrato aquoso da jabuticaba não teve efeito antimutagênico, bem como mutagênico. A Vit C aumentou no tecido hepático no grupo MYR quando comparada ao grupo MYR + CPA. Conclui-se que, nas condições experimentais utilizadas, o extrato da jabuticaba não apresentou potencial protetor aos danos induzidos pela CPA, nem modificou de forma relevante os parâmetros do estresse oxidativo nos animais tratados com MYR.

Analysis of jabuticaba aqueous extract against redox status
and mutageness in mice
 
ABSTRACT: Jabuticaba (Myrciaria ssp) is well known for having in its bark phenolic compounds with high antioxidant activity. Thus, this study aimed to evaluate antioxidant effects in the liver and brain and antimutagenic effects in the bone marrow of male Swiss mice with the aqueous extract of jabuticaba (MYR) and as a mutagenic damage-inducing agent to cyclophosphamide (CPA). Four groups were analyzed (N = 6): Control (C), CPA (25 mg.kg-1), Aqueous jabuticaba extract + CPA (MYR + CPA) and Aqueous jabuticaba extract (MYR). Through the micronucleus test in bone marrow cells, the frequency of micronuclei in polychromatic erythrocytes was evaluated for antimutagenic/mutagenic activity. The biochemical parameters evaluated were: Superoxide dismutase (SOD), Catalase (CAT), Glutathione-S-transferase (GST), Reduced Glutathione (GSH), Ascorbic Acid (VIT C) and Carbonyl. The results obtained showed that the aqueous extract of jabuticaba did not have an antimutagenic or mutagenic effect. Vit C increased in liver tissue in the MYR group when compared to the MYR + CPA group. It is concluded that, under the experimental conditions used, the jabuticaba extract did not show protective potential against damage induced by CPA, nor did it significantly modify the parameters of oxidative stress in animals treated with MYR.
Keywords: cyclophosphamide; oxidative stress; Myrciaria ssp; micronucleus test.

Published: March 2022

Background: Contrast induced nephropathy (CIN) is a grave but underdiagnosed complication of percutaneous coronary intervention that is associated with increased in-hospital morbidity and mortality. Our aim was to study the incidence, risk factors of CIN and applicability of Mehran risk score (MRS) in Indian population. Methods: A total number of 432 patients were enrolled in the study. Patients of age ≥ 18 years with known CAD, ACS who underwent PCI were included. Patients were followed for development of CIN. Results: Mean eGFR of 88.4 + 30.65 ml/min/1.73 m2 and mean contrast volume usage of 122.8 + 41.9 ml. 64 patients (14.8%) developed CIN. On univariate analysis, age (p 0.435), gender (0.125), hypertension (0.679), diabetes (0.177), contrast volume (0.155) were not associated with development of CIN whereas, smoking (0.021), hypotension (<0.001), heart failure (<0.001), anemia (0.001) and median eGFR (p < 0.001) were significantly associated with development of CIN. The incidence of CIN was 2.7 fold higher (OR : 2.68, 95% CI : 1.299-5.540, p = 0.008) in the intermediate group (MRS 6-10), 5.4 fold higher (OR : 5.403, 95% CI : 2.249-12.978, p <0.001) in the high risk group (MRS 11-15) and 51 fold higher (OR : 51.059, 95% CI : 18.195-143.278, p <0.001) in the very high risk groups (MRS > 16) when compared to the low risk group (MRS < 5) respectively. Conclusions: The incidence of CIN in the very high risk group (MRS > 16) was substantially higher in our study (77.8 %) as compared to same group in Mehran study (57.3 %).

Published: March 2022

Background: Acute coronary syndrome (ACS), is ischemic heart disease of varying risk factors and clinical pattern and with immense health burden worldwide. Inflammation is believed to be an etiological factor in ACS, and neutrophil to lymphocyte ratio (NLR), to be a biomarker. Objectives: To describe the clinical pattern and risk factors of ACS in Afro-Arabs of Sudan and to evaluate the NLR as a severity marker. Method: In a total population, cross-sectional study, conducted in Al-Shaab Hospital- Sudan, clinical, laboratory and ECG data were used for ACS grouping into unstable angina (UA), non-ST-segment elevation myocardial infarction (NSTEMI) and STEMI. All patients underwent coronary angiography (CAG) and their Gensini score and NLR were calculated. Results: A total of 130 patients (62.3% men) of a median age of 58.0, 50.0-65.0 yrs., (range 32.0-82.0), were diagnosed with ACS; 44.6% STEMI, 37.7% NSTEMI and 17.7% UA. The median Gensini score was higher in STEMI (42.5, 12.0-71.0) and NSTEMI (40.0, 15.8-60.5) compared with UA (10.0, 5.0-23.0), p 0.002, similarly, was the NLR; 3.5, 1.6-4.6; 2.9, 1.5-3.8 and 0.9, 0.8-1.1, respectively p<0.001. Furthermore, the NLR in concordance with CAG findings p<0.001. Finally, hypertension, diabetes mellitus and dyslipidemia, respectively, were stronger ACS risk factors in women than in men unlike smoking, and family history imposed the least risk. Conclusion: While the ACS clinical pattern was in-line with literature, the risk factors order was different, and it was different between sexes. Importantly, the NLR strongly associated with ACS severity, but failed to distinguish between NSTEMI and STEMI.

How Should Historians Talk about Spatial Agency?
Authors: Stock Paul
Published: March 2022

In recent years, it has become commonplace to argue that space is an important topic in the humanities and social sciences. But what does space do? Can we speak of space as having agency? Historians’ responses to these questions are strikingly varied. Some propose an almost deterministic role for spatial characteristics, while others deny that space can have any causal function at all. This article seeks to navigate a path between these unsatisfactory extremes. It uses insights from material culture studies and actor-network theory to discuss ways of re-framing agency as an assemblage of human and non-human affects. Agency can thus be defined not in terms of first causes and definitive outcomes, but instead as a coincidence of occurrences. This allows historians to speak of “spatial agency” as the emplacement of affective elements, the gathering of agencies at a particular site and moment.

Published: March 2022

BACKGROUND

Cerebrovascular events and infection are among the most common complications of left ventricular assist device (LVAD) therapy. The authors reported on a patient with an infectious intracranial aneurysm (IIA) associated with LVAD infection that was successfully occluded by endovascular therapy.

OBSERVATIONS

A 37-year-old man with severe heart failure received an implantable LVAD. He was diagnosed with candidemia due to driveline infection 44 months after LVAD implantation, and empirical antibiotic therapy was started. After 4 days of antibiotic treatment, the patient experienced sudden dizziness. Computed tomography (CT) revealed subarachnoid hemorrhage in the right frontal lobe, and CT angiography revealed multiple aneurysms in the peripheral lesion of the anterior cerebral artery (ACA) and middle cerebral artery. Two weeks and 4 days after the first bleeding, aneurysms on the ACA reruptured. Each aneurysm was treated with endovascular embolization using n-butyl cyanoacrylate. Subsequently, the patient had no rebleeding of IIAs. The LVAD was replaced, and bloodstream infection was controlled. He received a heart transplant and was independent 2 years after the heart transplant.

LESSONS

LVAD-associated IIAs have high mortality and an increased risk of surgical complications. However, endovascular obliteration may be safe and thus improve prognosis.
Catastrophic delayed cervical arthroplasty failure: illustrative case
Authors: Carrera Diego A. , Ricks Christian B.
Published: March 2022

BACKGROUND

Cervical disc replacement (CDR) is an increasingly used alternative to fusion for symptomatic cervical disc disease. While more studies have suggested favorability of CDR over fusion procedures, limited data exist regarding implant fatigability. Here, the authors present a unique and previously unreported failure of the M6-C prosthesis causing spinal cord injury.

OBSERVATIONS

A 49-year-old female with history of cervical degenerative disease and prior C4–7 M6-C arthroplasty presented 9 years later after a minor fall from standing. She endorsed bilateral hand numbness ascending to forearms and shoulders, with dysesthesias and weakness. Imaging showed fractured arthroplasty penetrating the spinal cord. Revision surgery found a ruptured arthroplasty annulus with metal piece piercing the spinal cord. Partial C4 and C5 corpectomy was performed to remove the integrated fins of the arthroplasty and inspect the cord and dura. This was reconstructed with a corpectomy cage and plate. The patient made an excellent recovery, with improvement in her weakness and resolution of her sensory symptoms.

LESSONS

Possibility of fatigue-related failures presenting years after implantation have only been infrequently reported but can be catastrophic for patients. The authors encourage further discussions in this area, increased counseling with patients, and recommend a patient registry to better document adverse events.
RESEARCH OF RELIABILITY OF WORK AND MEANS OF DIAGNOSIS OF TECHNICAL CONDITION OF FUEL EQUIPMENT
Authors: MELNIK Y. , MELNIK A. ,   Chernyatyn Vocational College of VNAU
Published: March 2022

The fuel system must provide an uninterrupted supply of fuel for the engine to operate in all possible modes of operation. Diesel fuel can be contaminated during transportation and subsequent storage, it can get dust from the air. Clogging of diesel fuel is also possible during engine operation, especially if the fuel tank is refueled at the same time as the technological operation. It is established in the article that mechanical impurities (mainly small particles of silica and alumina) harmful to the system get into diesel fuel. These particles have a very high hardness, equal to or even greater than the hardness of steels used in the manufacture of fuel equipment parts. Getting into the gap between the plunger and the sleeve of the fuel pump, such particles can get stuck in it and during the operation of the pump will erase the surface of the plunger and the sleeve. The jamming of the particles at the time of fuel supply under the action of pressure, the sleeve of the fuel pump is deformed. Larger particles can penetrate into this enlarged gap (it can be two to three times larger than the initial one, which is 2 to 3 μm). After cutting and pressure drop, the sleeve is tightened and clamps the particles that have penetrated into the gap. As a result, as the parts of the plunger pair wear, the radial gap between them increases, the leaks increase and the supply pressure decreases. For reliable operation of the engine constant and thorough cleaning of fuel is necessary therefore in fuel system for this purpose necessarily include fuel filters. Every third case of engine repair is associated with the failure of fuel equipment. Operation is often characterized by conditions when individual units, the engine as a whole work to partial disability without sufficient preventive measures.

The material presented in the article contains the results theoretical research, in terms of research and implementation in production technological design methods for the operational construction of mathematical models’ assembly processes of electronic devices and the choice of optimal parameters of their parts. This technique is based on the statistical principles of active planned experiment, which are currently widely used in various fields of science and technology. The use of these principles, in contrast to traditional methods of conducting a passive experiment and processing the results obtained in this case, allows to drastically reduce the time and material costs for a reliable mathematical description of complex physical laws that underlie the processes of compiling modern electronic devices and choosing the parameters of the parts included in them. The proposed methodology provides for a modification of the principles of an active planned experiment, which can be used when working with electronic devices consisting of independent (explained in the text of the article), in a certain sense, functional units or cascades, the mutual influence of which on the operation of the device is known in advance. It allows you to create such statistically determined models of radio electronic devices that can significantly reduce the labour intensity and economic costs necessary for setting up an experiment. The selection of primary factors included in an active planned experiment should be based on a thorough analysis of the principles of operation and design features of assembly objects, the physical essence of a particular technological process, as well as a study of the experience of mass production and the results of previous research in the relevant areas of technology. The success of the entire active planned experiment and the possibility of effective use of the obtained mathematical model in the design and technological preparation of production almost completely depend on the successful choice of factors. The purpose of the article is related to the development of a technique for the rapid construction of mathematical models of the assembly processes of radio-electronic devices and the selection of the optimal parameters of their parts.

The ways of regulating adhesion of fluoroplastic coatings to metal surfaces are analyzed. It has been established that polymer and metal modification is necessary to increase the adhesive strength and resistance of fluoroplastic coatings. The relative impact of the nature of the metal on the strength of adhesive compounds of polymer – metal is less influenced by the nature of the polymer. The strength of metal compounds is significantly affected by the activation of the metal surface by mechanical treatment (grinding etc.). Various methods of oxidation, etching, metal phosphating are recommended to increase the adhesive strength of fluoropolymer coatings. Method of investigation of adhesion and resistance to scratch damage of coatings is given. The influence of composition and temperature-time conditions of the ground layer formation of the coating on adhesive strength of metal-polymeric compounds was investigated. Detailed operation modes are described. The properties of the ground layer of fluoropolymer Ф-30П are given. The peculiarities of the fluoroplastic coating ground layer formation are outlined. The technology of application of the fluoroplastic coating ground layer on electroplating of metal surfaces has been developed. The coating on the metal surface was done by electrostatic spraying of the ground layer powder at an electric field voltage of 50 kV. The deformation and strength properties of the unstabilized Ф-30П fluoroplast are found to be quite high, which together with high adhesive strength makes it possible to recommend this polymer as primer. It is also advisable to melt the ground layers in more rigid temeperature-time modes (melting temperature 2600 C, duration – 2 hours) in order to ensure higher adhesion strength. The adhesive strength of the Ф-30П fluoroplastic coating can be increased by 10-15% by additional heating at a temperature of 2400 C for two hours. Analysis of the results showed that the resistance of fluoroplastic coatings based on Ф-30П to damage by scratching with an increase in the graphite content of C-1 from 15% to 25% increases by a factor of 2.11, and inserting to coating with 25 mas.% of C-1 graphite additional 3 mas. % of the aerosil-based amino-ergoholozenese – 3.16 times. The additional termoprocessing of these coatings increases the resistance to damage by scratching by 30 per cent. Recommendations on the use of research results for obtaining fluoroplastic coatings with high-adhesion to metal surfaces are given.

Recently, in Ukraine and in other countries, special attention is paid to the quality and technological heredity of finished products, which receive metal treatment by pressure. One of the important tasks in the production of parts is to ensure the high quality of the working surfaces and improve the physical and mechanical characteristics of the surface layer of their material. One of the most economical and effective ways of solving this problem is to strengthen details by surface plastic deformation (PPE), which allows to more fully realize the potential properties of structural materials in real details of complex structure and in details with stress concentrators. Using the methods of deformability theory, the value of the resource used and its dependence on the parameters of the process of surface plastic deformation is determined at the design stage. It is necessary to have information about the stress-strain state in the deformation cell and the laws of its change, depending on the parameters of the process of surface plastic deformation. The most effective direction for improving the technology of roughing roller is the choice of rational parameters of the geometry of the tool and process technology. Analyzing the obtained results it can be concluded that there is a significant nonmonotonic deformation due to the fact that there is a wave in front of the roller in which there is a stress tension, while under the roller there is a stressful state of comprehensive compression. In addition, when changing the direction of obstruction, the sign of tangential stresses, which contributes to the partial recovery of microcracks and, consequently, to reduce the value of the used resource of plasticity. According to the results of researches, it was established that the optimal mode is treatment, in which a tool with three turns is used and the routing is performed once in two opposite directions. This allows you to increase the hardness of the original workpiece almost twice and get a surface with a minimum roughness. The obtained results show the advantage of nonmonotonic deformation, as in these cases, with the same degree of deformation of the surface layer of the metal, the resource of plasticity in the first case is much smaller.

The issues of uninterrupted power supply and improvement of electricity quality indicators in such distribution networks are relevant. In rural electrical networks of alternating current, the total transmitted power S contains active P and reactive Q power of inductive nature, which is due to active – inductive load and therefore, respectively, the current in the power supply system has active and inductive components. The load consumption of active and reactive power characterizes the coefficient of active power cosφ, which is defined as the ratio of active power to total. Quite often in energy the reactive power factor tgφ is used as the ratio of reactive power to active power. In our opinion, this more clearly reflects the ratio of the amount of energy consumed. The article considers the conditions for providing the necessary values ​​of the power factor in the mode of compensation of reactive power of the power supply system of low-power processing enterprises of agricultural products. The analytical dependence of the power of the compensation device required to ensure the desired value of the power factor is determined. An algorithm for calculating the harmonic components of the capacitor bank current in the network with sources of higher harmonics has been developed. The calculations take into account the dependences of current harmonics on the load of 0.4 kV network consumers. Conducted analysis of the occurrence of possible resonant phenomena in the 10 (6) kV network. The value of the capacitor bank current is determined in the case when the source of the higher harmonics is the power supply system itself or the consumers of electricity in the 0.4 kV network.

Several Trichoderma species are known to be able to establish beneficial interactions with plants. These interactions are complex and involve different mechanisms and modes of action that can act individually or together. The production of secondary metabolites, including volatile organic compounds (VOCs) is involved in these interactions and these compounds have been detected and characterized. Methodologies to evaluate the role of VOCs from Trichoderma in the biological control and in the plant growth promotion are some of the difficulties to study the subject. This review summarizes advances in knowledge of VOCs from Trichoderma and the methodologies/adaptations to evaluate the effects of VOCs in the selection of strains for biological control. The action of these VOCs is mainly mentioned for Sclerotinia sclerotiorum. This review also shows the possible classes and VOCs, which have the capacity to promote plant growth.

Este artigo analisa as trajetórias de jovens estudantes de pós-graduação que tomaram a decisão de migrar do Brasil para Portugal a fim de dar continuidade aos seus estudos. Busca-se compreender tais fluxos migratórios tendo em vista suas trajetórias e utilizando os conceitos de campo de possibilidades e projeto a partir das formulações do antropólogo Gilberto Velho. Recorremos à literatura contemporânea sobre a relação migratória entre Brasil e Portugal produzida por pesquisadores de ambos os países e realizamos entrevistas semiestruturadas para identificar o que os levou a migrar e como foi o processo anterior à sua partida, isto é, quais atitudes foram tomadas para deixarem seus lugares de origem. Concluímos que o comportamento e a narrativa desses indivíduos, suas práticas e seus discursos, mostraram-se bastante semelhantes em diversos contextos da sociedade contemporânea.
Colonialismo, luta de classes, racismo e subalternidade:
Authors: Sousa Joeline Rodrigues de
Published: March 2022

O uso do conceito gramsciano de subalternidade pelo grupo dos Subaltern Studies tem desdobramentos distintos das bases revolucionárias da Filosofia da Práxis, pois, ao aderir às tendências pós-modernas e às teorias “pós-coloniais”, contribuem para reforçar os questionamentos sobre a legitimidade de Karl Marx para contribuir com o debate sobre a relação entre exploração e opressão pelo colonialismo, especialmente na América Latina. Assim, este artigo busca recuperar as contribuições de Marx e de Antonio Gramsci e os elementos históricos que condensam o lugar da Filosofia da Práxis contra o colonialismo, o racismo e as formas que a subalternidade assume na sociedade de classes, como a “questão meridional” apontada por Gramsci, assim como a contribuição de intelectuais orgânicos que auxiliam na tarefa da tradutibilidade latino-americana, especialmente do Brasil, a partir da compreensão das contradições particulares e contemporâneas que acenam para as possibilidades sócio-históricas de organização e de construção do devir.

Introduction. The development of various aspects of the base culture of primary school students is a global goal of primary education. In this context, the skills of safe and responsible behavior towards one’s own life are considered a crucial objective and the basis for a child’s vital interests. The study aims to create and consider pedagogical conditions for building safe behavior skills. Methodology and organization of research. Given the readiness of children for safe behavior, the action-oriented game sets were selected and developed to build the basic safe behavior skills, with the effectiveness of these games tested experimentally. The methods employed to do these tests are the Correction test (to determine the level of attention development in schoolchildren) and the Schulte Tables method (to determine the speed of visual roughly-search movements in the first graders). Coordination ability level was assessed through the testing of shuttle running 3X10 m (s), static balance (s), and the ability to differentiate muscle efforts, i.e., to hit the target (the number of hits in 5 attempts to hit vertical targets and 5 attempts to hit horizontal targets). The study results have proved that specially selected action-oriented games enhance the culture of safe behavior of junior schoolchildren.

Introduction. The transformation of a teacher’s professional activity in the context of standardization is a priority objective of Russian education. The paper aims to determine the aspects of extrapolation of teacher’s professional activity standardization practice in foreign countries into the practice of an educational organization. Methods. A comparative analysis of foreign teacher’s professional standards revealed their common and distinctive features. It also identified universal and contextual characteristics of conditions for the foreign experience extrapolation. The extrapolation method established the current strands of extrapolation and productive practices of foreign experience for translation into Russian education. The modeling made it possible to design changes in the teacher’s activity and develop a concept of its transformation under standardization. Results. Analysis of theoretical and normative sources on the adoption of teacher’s professional standards in the Russian Federation indicates that the experience of teacher’s professional activity standardization in foreign countries is relevant for Russian education. In this regard, a concept of teacher’s activity transformation to the teacher’s professional standard in an educational organization is proposed. It rests on the extrapolation directions (motivational aspect, methodological support, education technology, and administrative resource of an educational organization) and the productive experience of foreign countries – Australia, England, Hong Kong, and Singapore. Conclusion. The relevance of the presented research materials is determined by the potential resource of extrapolation of foreign experience into the practice of an educational organization, against the background of disregard of productive practices of teacher’s professional activity standardization in foreign countries and procrastination of the adoption of the teacher’s professional standard in the Russian Federation.

In this empirical research, the effects of macroeconomic variables and the incentive policies implemented in Turkey on the employment, informal employment and income have been investigated in Turkey. Electricity consumption (Economic Growth), the USD/TL exchange rate and inflation variables were used as the macroeconomic variables. The employment incentives that are implemented by the Laws Number 5510, 25510/16322, 26322, 6111, 14857 and 05746/15746 among the employment incentive policies implemented in Turkey were used as variables. The first lagged values of employment incentives from the Laws No. 5510, 26322 and 6111 significantly affected informal employment. The first lagged values of the variables of economic growth as the macroeconomic variable and Law No. 5510 have a positive effect on reducing informal employment. As a macro-economic variable, USD/TL exchange rate has a negative and relatively high efficiency.
