Positionalities of Precarity
Authors: Nititham Diane Sabenacio
Published: January 2022

The ongoing neoliberal restructuring of higher education has led to the growth of contingent and temporary non–tenure track faculty positions. Drawing on the rich and growing literature on the academic precarity produced from this contingent labor, this autoethnography examines how the author sought to find an academic home while navigating the neoliberal university. First, the author discusses autoethnography as a method of resistance and situates positionalities of precarity as a state of chronic instability. Second, the author details experiences as a contingent faculty member working in different institutions. This section includes dealing with heavy workloads, juggling multiple contracts, and handling self-doubt, guilt, fear, exhaustion, and disposability. The third section analyzes the internalization of these contingencies while handling bullying and microaggressions from students and colleagues. Last, the author discusses reflections and opportunities for transformational resistance in hopes to work toward a more equitable educational and working environment. As an Asian American academic, the author also aims to add a voice to under-represented faculty in the academy.
Hypothalamic KNDy neuron expression in streptozotocin-induced diabetic female rats
Authors: Enomoto Hiroyuki , Iwata Kinuyo , Matsumoto Keisuke , Otsuka Mai , Morita Akio , Ozawa Hitoshi
Published: January 2022

Kisspeptin neurons, i.e. KNDy neurons, in the arcuate nucleus (ARC) coexpress neurokinin B and dynorphin and regulate gonadotropin-releasing hormone/luteinizing hormone (LH) pulses. Because it remains unclear whether these neurons are associated with reproductive dysfunction in diabetic females, we examined the expression of KNDy neurons detected by histochemistry in streptozotocin (STZ)-induced diabetic female rats 8 weeks after STZ injection. We also evaluated relevant metabolic parameters – glucose, 3-hydroxybutyrate, and non-esterified fatty acids – as indicators of diabetes progression. Severe diabetes with hyperglycemia and severe ketosis suppressed the mRNA expression of KNDy neurons, resulting in low plasma LH levels and persistent diestrus. In moderate diabetes with hyperglycemia and moderate ketosis, kisspeptin-immunoreactive cells and plasma LH levels were decreased, while the mRNA expression of KNDy neurons remained unchanged. Mild diabetes with hyperglycemia and slight ketosis did not affect KNDy neurons and plasma LH levels. The number of KNDy cells was strongly and negatively correlated with plasma 3-hydroxybutyrate levels. The vaginal smear analysis showed unclear proestrus in diabetic rats 3–5 days after STZ injection, and the mRNA expression of kisspeptin in the ARC was decreased 2 weeks after STZ injection in severely diabetic rats. Kisspeptin neurons in the anteroventral periventricular nucleus (AVPV), which induce an LH surge, were unaffected at 2 and 8 weeks after STZ injection regardless of the diabetes severity. These results suggest that diabetes mellitus progression in females may negatively affect ARC kisspeptin neurons but not AVPV kisspeptin neurons, implicating a potential role of ARC kisspeptin neurons in menstrual disorder and infertility.

Published: January 2022

The electronic band structure of the solid-state CdSe0.5S0.5 thin film solution in the framework of the density functional theory calculations are investigated. The structure of the sample is constructed on the original binary compound CdS, which crystallizes in the wurtzite phase. Transformations of the electronic energy spectra for the solid-state CdSe0.5S0.5 solution, which occur in the process of transition from bulk crystals to thin films, are analyzed. The refractive index and high-frequency dielectric constant are calculated. All of the calculated parameters correlate well with the known experimental data.
Wingless Angels: Homer as an Authoritative Historical and Aesthetic Source in Early Modern Period
Authors: Riklius Tomas
Published: January 2022

This paper discusses the unusual reference to Homer in Federico Borromeo’s De pictura sacra in which Homer is quoted as an authoritative aesthetic and historical source to justify the depiction of wingless angels by Michelangelo. It is said that the great Greek poet represented the gods without wings as if they could move with their feet joined together. The first part of the article examines this relatively obscure remark and its possible sources. One of the reasons for such a quotation is the general Renaissance attitude towards Classical texts to provide a historical perspective and establish an authoritative argumentation. However, a closer analysis discloses that Borromeo refers to Homer not simply as an aesthetic and historical but as a quasi-theological source of God-inspired wisdom.
Motives for Women’s Participation in Military Conflicts: The Ukrainian Case
Authors: Lapėnaitė Miglė
Published: January 2022

This article analyzes the motives for direct (in military actions) and non-direct (in administrative or military support actions) participation of Ukrainian women in the ongoing Russian-Ukrainian military conflict that began in 2014. It aims to reveal the motives that have led pro-Ukrainian women to take part in defending their country by allowing the participants of the study to speak for themselves. The article draws on twenty (20) e-interviews with women who were involved in the war in Ukraine and five (5) semi-structured interviews with people who due to their professional activities were able to observe the conflict from the inside (journalists, NGO workers, and war photographers), as well as secondary sources available. Content analysis of the interview data was implemented. The article identifies four main motives for participation in war: patriotism, grievances, personal loss and suffering, and women’s empowerment. This information corresponds with similar studies conducted elsewhere in the region.
On T(n, 4) Torus Knots and Chebyshev Polynomials
Authors: Pavlyuk A.M.
Published: January 2022

The Alexander polynomials ∆n,3(t) and ∆n,4(t) are presented as a sum of the Alexander polynomials ∆k,2(t). These polynomials are also expressed in the form of a sum of Chebyshev polynomials of the second kind. These expansions allow one to introduce the "coordinates" in corresponding bases, which are proposed to be the numerical invariants characterizing links and knots.

Mysterious Quantum Effects Observed with Neutrons
Authors: Rauch H.
Published: January 2022

Single-particle interference phenomena can be observed with neutrons, and the "entanglement of degrees of freedom", i.e. the contextuality, can be verified and used in further experiments. Entanglement of two photons or atoms is a complementary situation to the double-slit diffraction of a single photon, neutron, or atom. In this respect, neutrons are proper tools for testing quantum mechanics, because they are massive, they couple to electromagnetic fields due to their magnetic moment, and they are subject to all basic interactions, and they are sensitive to topological effects as well. The4π-symmetry of spinor wave functions, the spin-superposition law, and many topological phenomena can be made visible, which shows interesting intrinsic features of quantum physics. Related experiments will be discussed. Deterministic and stochastic partial absorption experiments can be described by Bell-type inequalities. Recent neutron interferometry experiments based on post-selection methods have renewed the discussion about quantum non-locality and the quantum measuring process. It has been shown that interference phenomena can be revived even when the overall interference pattern has lost its contrast. This indicates a persisting coupling in the phase space even in cases of spatially separated Schrödinger cat-like situations. These states are extremely fragile and sensitive against any kind of fluctuations and other de-coherence processes. More complete quantum experiments also show that a complete retrieval of quantum states behind an interaction volume becomes impossible in principle.

Anti-religious policy of the Bolshevik government in the early 1920s (on the example of Roman Catholics of Katerynoslav)
Authors: Mosiukova Natalia
Published: January 2022

The aim of the article: to analyze the conditions of existence of the Roman Catholic community of Katerynoslav in the first years of the establishment of Bolshevik power. Methods: historical-genetic, historical-systemic. The main results: the attitude of the Bolsheviks to the Church and the methods they used in their anti-religious activities in the early 20s of the twentieth century is highlighted; the factors influencing the attitude of the authorities to the Roman Catholics of Katerynoslav are revealed; the measures taken by the Bolsheviks to influence the Poles and Lithuanians living in the provincial city at that time are studied, as well as the results of this activity. Concise conclusions: The destruction of religion was part of the strategic plans of the Bolsheviks, and after the establishment of their power, they launched an attack on the Church. In the early 1920s, the measures included repression, looting of churches, and moral pressure on the faithful. The initiation of the persecution was the Bolshevik Party. The Extraordinary Commission took an active part in this process; it gave effective methods of realization of the tasks, and also carried out repressions. The position of the Poles was influenced by the relations of the Soviet state with Poland. In 1920, they were significantly complicated by the war between these countries. The leaflets issued by the Bolsheviks called for the overthrow of the state system and terrorist activities in Poland. The policy of the Soviet government, repressive activities against the Church (including the RCC), and aggressive rhetoric towards Poland pushed local Poles to leave for their historical homeland. The attempt to Sovietize the refugees was not very successful, and in 1921–1922 representatives of the nations that formed the Roman Catholic environment of the provincial center left Katerynoslav in echelons. The authorities also tried to export revolutionary ideas to neighboring countries. Not only refugees but also the Poles who lived in the city before the war went to Poland. Many members of this national minority in Katerynoslav did not belong to the parishioners of the church in the mid-1920s, which means that they were under the influence of anti-religious propaganda or were afraid to openly profess their faith. Practical meaning: the results of the research can be an integral part of the study of the history and religion of national minorities at the national level. The scientific novelty of the article is that the author conducts a study of the peculiarities of living conditions of the Roman Catholics in Ekaterynoslav in the early 20s of the twentieth century for the first time. Type of article: research.
Everyday life and work of Polish doctors of the interwar period : according to the diaries
Authors: Kotichenko Anna
Published: January 2022

The purpose of the article is to reveal the image and everyday practice of doctors of state medical institutions in interwar Poland through diaries written by them. Research methods: historical-genetic, historical-comparative, descriptive, historical-typological. The main results: the article highlights the views of Sickness Funds patients on everyday life, profession and its importance. The life paths of doctors, their motives for work, survival strategies in the province and in the capital are clarified. The author’s focus is on everyday professional life, relationships with patients, which generally depicts the status of doctors in the Second Polish Republic. The content of Polish doctors’ activities, their efforts to improve health of population are revealed. Much attention is paid to the analysis of the diaries and the nature of problems and challenges faced by doctors of Sickness Funds. Working conditions of Polish doctors in the interwar period were not easy and the main reason of this was the economic crisis of the 30’s of the 20th century. First of all, the lack of material support, low level of consciousness of the population, patients’ distrust and contempt of patients for doctors, the activities of healers and quacks were also noticeable. At the same time, insufficient salary and limited opportunities often forced doctors to buy the necessary things at their own expense. The psychological atmosphere of the doctor’s work was not easy either and it was often manifested in abusive or dishonest attitude of patients, daily risks, provocations from the local population or their stereotypes about treatment. Constant fatigue, stress and exhaustion accompanied most doctors during this period. The diaries represent a social portrait of a doctor of the interwar period, a new generation of young people, whose professional activity coincided with the years of the independent Polish state, however, it was limited primarily by the challenges of the economic crisis. At the same time, the idea of competition was aimed at PR, advertising and promotion of the Social Insurance Administration of Poland. The main goal was to strengthen the confidence of Poles in the main state institution of social security and encourage the population to pay insurance premiums. The life destinies of the contest participants are also traced. As it turned out, all the doctors whose diaries were published in 1939 were killed during the war. Practical significance: the obtained results can be used in preparation of monographic studies, generalizations, textbooks and manuals on the history of Poland, socio-cultural history of Central and Eastern Europe, biographies. Scientific novelty: for the first time the analysis of diaries and memoirs of Polish doctors are performed, their views and work are studied; attitude to the chosen profession, an attempt to trace the strategies of popularization of the doctor’s profession in interwar Poland are described. Article type: research.

Os crescentes índices de violência doméstica demonstram como o Brasil ainda se constitui a partir de uma cultura patriarcal, machista e racista, apoiada na concepção de mulher enquanto bela, recatada e do lar (VEJA, 2016). A partir da Teoria Semiolinguística proposta por Patrick Charaudeau (2008), realizamos neste trabalho uma análise dos atos de linguagem presentes na canção Maria da Vila Matilde, composta por Douglas Germano e interpretada por Elza Soares. A abordagem teórico-metodológica utilizada neste artigo está baseada na classificação do texto a partir dos Modos de organização do discurso, tendo o Modo Enunciativo como foco. Este trabalho é de cunho descritivo-analítico-interpretativo, o que esboçamos em um quadro elaborado a fim de organizar a música em virtude dos seus modos enunciativos. Logo após essa descrição feita por meio do quadro, analisamos e interpretamos de que maneira tais modos constituem sentido, especialmente o sentido de enfrentamento/empoderamento.
Novafala
Authors: Niederauer Carina Maria Melchiors , Pasquali Anna Carolina
Published: January 2022

Este estudo tem por objetivo por à mostra o poder da linguagem na organização social. Para isso, faz-se a análise da obra literária, 1984, de George Orwell, em especial, da criação de uma nova língua no país fictício da Oceânia, que se revela um importante mecanismo de controle da população. Para a análise dessa nova língua, chamada de Novafala, busca-se na noção de signo ideológico, como compreendida pelo Círculo de Bakhtin, em especial na obra Marxismo e filosofia da linguagem (2017), de Volóchinov, o aporte teórico necessário para explicitar como o uso da língua pode contribuir para o controle e dominação de um povo. Como resultado, é possível observar que a eliminação da língua falada pela população e a criação de uma nova língua visa anular o pensamento crítico, tornando as pessoas meras reprodutoras de opiniões, sem qualquer tipo de reflexão.
Um sistema de dispersão interdiscursivo
Authors: Cardoso Roseli , Pessoa Fátima
Published: January 2022

Este estudo apresenta a importante intersecção entre conceitos de dois pensadores do funcionamento discursivo, considerados como os pilares na descrição e interpretação da relação conflituosa entre os discursos dos pescadores tradicionais e representantes governamentais da pesca. A priori Michel Foucault (1996, 2012, 2013) embasa a análise das relações de saber e poder no espaço da pesca em duas Unidades de Conservação. No mesmo grau de relevância para a análise deste empreendimento, acrescenta-se os postulados de Dominique Maingueneau (2005, 2008, 2015), para compreender a constituição dos grupos implicados na prática discursiva no contexto do trabalho como ordem institucional que define, pelo que dizem e o que fazem, os sujeitos da pesca dentro das comunidades. Reflete-se sobre a tensão na relação entre discursos e reorganização social da pesca nas Reservas Extrativistas Marinha do Brasil – RESEX- Caeté Taperaçu (PA) e Araí-Peroba (PA). Vislumbra-se, pelo funcionamento discursivo implicado em documentos oficiais e em narrativas de pescadores uma governamentalidade de controle social inscrito na relação entre território, população e segurança, alicerçada na economia política do Estado que exercita o poder no triângulo da disciplina, da soberania e da gestão governamental.
Uma cenografia parasita

Published: January 2022

No contexto de migração para espaços digitais, em que eleições são afetadas pela acirrada colonização das redes sociais e o mercado se reformula para absorção de consumidores remotos, surge uma forma parasitária de capitalizar sobre a credibilidade do jornalismo tradicional. O objetivo deste trabalho consiste em analisar a cenografia do Jornal Cidade Online e suas relações dialógicas e parasitárias com a imprensa tradicional para a construção de um ethos de jornalismo comprometido com a verdade na captação de público para seu mundo ético. O corpus é composto por excertos retirados do Jornal da Cidade Online e pelo layout do site. A pesquisa se caracteriza como descritiva, bibliográfica e documental, de abordagem qualitativa. Conclui-se que o Jornal da Cidade Online opera uma cenografia que parasita a identidade visual de jornais tradicionais como modelo enquanto opõe sua linha editorial como antimodelo, o que leva à projeção de um ethos de jornalismo legítimo que visa à incorporação do público ideologicamente alinhado ao jornal. Como contribuição, esta pesquisa oferece, através de uma perspectiva interdisciplinar, um diagnóstico inovador para o problema da desinformação que corrói a legitimidade de veículos tradicionais e a confiança do público no jornalismo enquanto fiscal combativo dos agentes do Estado.

Authors: Camargo Gabriella Cristina Vaz , Souza Nathan Bastos de
Published: January 2022

O objetivo deste artigo é estudar os sentidos do signo “novo mundo” a partir de três posts publicitários da Latam Airlines, publicados em sua página do Facebook. O recorte privilegiou os posts com imagem e texto em que aparecia materialmente o signo “novo mundo”, em uma amostra discursiva tomada entre os meses de março e setembro de 2020. Apresentamos uma seção teórica em que discutimos o signo ideológico conforme Volóchinov (2017) e uma seção em que tratamos da questão do enunciado concreto e sua abordagem metodológica a partir do Círculo de Bakhtin. A análise relaciona os três posts publicitários com momentos distintos de compreensão da pandemia de Coronavírus pela sociedade: um “novo mundo” em emergência, no primeiro, em consolidação, no segundo; e como já dado no terceiro post. Consideramos, por fim, que o “novo mundo” que a Latam constrói em seu discurso é sua forma de enfrentamento da pandemia e sua estratégia ideologicamente construída para vender passagens, que ocorre simultaneamente à retomada das atividades econômicas da sociedade.

MOTIVATION OF ENGLISH-SPEAKING STUDENTS TO STUDY VETERINARY MEDICINE AT TRAKIA UNIVERSITY
Authors: Balieva G.
Published: January 2022

International migration of tertiary students is a global trend which gives higher education institutions a strong incentive for quality development, service improvement and competitiveness. Research has shown that the attractiveness of educational services is dependent on factors with national-international characteristics and factors based on the demographic profile of students. PURPOSE: The aim of this study was to investigate the motivators which influence students` personal attitudes towards studying veterinary medicine in English at Trakia University, Bulgaria. METHODS: A five-year survey among 93 first-year English speaking students in veterinary medicine at Trakia university was conducted through anonymous written questionnaire between 2015 and 2019. Data obtained were statistically processed. RESULTS: Significant differences were found for several factors which drove respondents` motivation in choosing their master’s degree. Among these factors were gender, parents` occupational profile, country of origin, tuition fees, as well as existing experience in breeding, interaction with animals and volunteering in the veterinary field. The most preferred source of information for veterinary medicine programmes and universities appeared to be recommendations from respondents` relatives, friends and mentors. CONCLUSION: Understanding the motivation drivers of English-speaking veterinary students will help the improvement of the educational service offered and the competitiveness of the institution internationally.

Published: January 2022

The paper states the problem of evaluation of total minimum contract value including transaction costs of an industrial enterprise when distributing an order among several suppliers. We present the model, where transaction costs on opportunism reduction are the control parameter. Numerical experi- ments were carried out. The paper states the optimization problem for determination of minimum total value of contracts, considering transaction costs of an industrial enterprise in case of diversification the order among several suppliers. Transaction costs are divided into three groups: the costs of information search about the supplier including qualifying selection of the suppliers; negotiation costs with the sup- plier and costs of supplier opportunism reduction. We present the model where the total contract value consists of the value of the delivered goods, transaction costs and losses in case of non-delivery of goods. The model also takes into account probable losses from both passive and active opportunism. A number of numerical experiments was carried out. That allowed to establish the existence of a minimum for the target function and showed the stability of the model for changes of input parameters.

Published: January 2022

The article is devoted to the application of the Data Mining «Neural Network» algorithm for analyzing the available data of potential bank customers. The article discusses the possibilities and features of the creation and use of neural networks when conducting a comprehensive data analysis and building a system for further forecasting. The authors set the task of identifying the main characteristics of potential customers that affect a person’s desire to continue interacting with the bank after offering services to them. Based on the task, the neural network is created on the basis of the created multidimensional data structure to be able to predict the prospects of interaction with each client. The constructed neural network allows identifying potential customers based on new customer data to develop further marketing campaigns and optimize banking strategies aimed at improving long-term customer interaction.
RATING AND CONTROL OF COMPLEX OBJECTS IN UNCERTAINTY CASES
Authors:   Perm National Research Polytechnic University, Alekseev Alexander
Published: January 2022

Statement of the rating and control of complex objects problem under uncertainty is formulated. Seven methods are presented for assessing the state of individual properties of a complex object, designed for various conditions of uncertainty. The source of uncertainty can serve as objective tools of control, that is, estimates of particular properties of an object can be either exact values ​​on a set of real numbers or interval estimates, in addition to this, the state of individual properties can have a probability distribution about the possible state of an object. The qualitatively described properties of an object are subject to uncertainty, the source of which is the subjectivity of the judgments of experts involved in their evaluation. It is important that experts can also evaluate quantitative indicators, for example, in cases where the tools of objective control are not available, that is, subjective input methods are applicable not only to qualitative indicators, but also quantitative ones. In order to aggregate information about private properties, it is proposed to use the matrix mechanisms of complex assessment that are known and obtained by the author. The defined matrix mechanisms of complex evaluation are as follows: the tree fuzzy rating mechanism with an additive-multiplicative approach and two max-min approaches to set theoretic operations, as well as two continuous complex evaluation mechanisms. Six model examples demonstrate procedures of aggregating two criteria with accurate real values, as well as with different uncertainty such as interval values, fuzzy values and F-Fuzzy values.

The relevance of the study of the real estate prices dynamics in the city of St. Petersburg is shown. The criterion and factors influencing the object of modeling are determined. Normalized values of the criterion and factors are calculated. The mutual correlation of factors is investigated. A linear multifactor model and a model in the state space are built, it was proved that they cannot be used due to its poor predictive properties. A regression-differential model of prices changing for primary real estate in St. Petersburg is built, taking into account the mutual influence of factors, the possibilities of influence on its dynamics are revealed. Based on the linear multifactor model and the regression-differential model, the forecast of price changes for the next three years is made.
CLASSIFICATION OF THE GAME THEORY MODELS IN PROJECT MANAGEMENT: LITERATURE REVIEW
Authors:   Peter the Great Saint-Petersburg Polytechnic University, Gintciak Aleksei

The article provides a review of existing project management models and methods using particular game theory tools. The purpose of the review is to determine the current level of the research in this scientific topic, and to determine the most applicable classes of game-theoretic models and methods for the study of particular strategic interactions types that arise at certain stages of the project life cycle. Scientific papers published in international peer-reviewed journals and conferences proceedings over the past 10 years are used as an information base for analytical research. The first part of the article is devoted to the description of the most successful examples of the game-theoretic models’ application for the study of strategic interactions within project management processes. Based on this part, a conclusion is made about the locality of the game theory tools application for solving project management problems, as well as the expediency of developing an integrated approach that allows describing strategic interactions in project management processes in an invariant form. The second part of the article is devoted to the definition of criteria for the existing game-theoretic models’ classification. The classification criteria selected in this part of the article are used later in the third and fourth parts. The third part of the article is devoted to the classification of existing models by the composition of agents participating in the strategic interaction. According to this criterion, the models and methods are divided into the classes "Public-private partnership", "Contractor – contractor", "Contractor – subcontractor", "Subcontractor – subcontractor", "Interactions within the team", "Others". Based on the results of this classification, a conclusion is made about the dominant attention of researchers to the problems of organizing contractual relations and a clear lack of attention to non-contractual relations of performers within the project team. The fourth part of the article is devoted to the classification of existing models by their type. In this classification method, game-theoretic models are divided in two changes: strategic interactions are divided into simultaneous and sequential, as well as cooperative and non-cooperative (within the last class, into zero-sum games and non-zero-sum games). Based on the results of this classification, certain classes of game-theoretic models are determined that are most applicable in the study of strategic interactions in project management processes. The results of the work confirm the prospects of developing both particular game-theoretic models for describing specific strategic interactions that arise during the project implementation, and an invariant approach for describing a project as a complex of the stakeholders’ strategic interactions. The results of the work can be used by researchers to substantiate the relevance of their own research on this topic.

O texto tem por objetivo refletir sobre as diferentes formas de investigar/olhar a cidade. Procura apontar a necessidade de se buscar novas perspectivas para a exploração científica, destacando a riqueza dos encontros cotidianos que estão além do olhar científico. Para isso, este trabalho faz uma breve recordação dos limites da investigação científica e seu processo histórico de objetivação das relações sociais.
HIV e AIDS, passado e presente: os gays como representação social da doença
Authors: Lopes Pablo De Oliveira
Published: January 2022

Os primeiros casos brasileiros de infecção pelo HIV (da sigla em inglês, Vírus da Imunodeficiência Humana) e de AIDS (também da sigla em inglês, Síndrome da Imunodeficiência Adquirida) foram relatados em 1983. Os anos 1980 foram marcados pelo surgimento dessa infecção sexualmente transmissível, uma enfermidade que chegou a ser chamada de Doença dos 5H, em razão de casos identificados em homossexuais, hemofílicos, haitianos, heroinômanos (usuários de heroína injetável) e prostitutas (hookers em inglês), e foi responsável pela estigmatização de gays. A própria homossexualidade já foi considerada doença: em 1952, a Associação Americana de Psiquiatria publicou, em seu primeiro Manual Diagnóstico e Estatístico de Transtornos Mentais,que a homossexualidade era uma desordem, o que levou diversos cientistas a tentar comprovar que havia um distúrbio mental nos gays. Então chamada de homossexualismo, a homossexualidade foi incluída na Classificação Internacional de Doenças (CID) de 1977 pela Organização Mundial da Saúde (OMS). Em 1975, a Associação Americana de Psicologia deixou de considerar a orientação sexual como transtorno mental e a OMS seguiu o mesmo caminho em 1990. Apesar de não ser mais considerada uma doença, a homossexualidade ainda é associada a uma enfermidade: a AIDS. Além disso, para algumas pessoas, ser homossexual significa necessitar de cura. A sexualidade é um tema que controverso, um tabu, que desperta sentimentos e percepções distintos e é alvo de discussões em diversos segmentos da sociedade. Partindo de tais premissas, tem-se como problema de pesquisa: AIDS e homossexualidade ainda se confundem? Destarte, o objetivo desta pesquisa é mostrar se esta associação ocorre e de que maneira ela se dá. Para tanto, o presente ensaio, um estudo teórico escrito a partir de uma pesquisa exploratória, de caráter bibliográfico e documental, baseia-se em uma revisão de literatura especializada no domínio estudado, que utiliza o método de revisão narrativa, não sistemático e não exaustivo.

A pandemia do novo coronavírus tem trazido uma série de mudanças para a sociedade que extrapolam a crise sanitária de proporções mundiais. A necessidade de isolamento social impôs a necessidade de trabalhar de casa para uma parcela da população que pôde recorrer a esta alternativa e com isso impulsionou o crescimento dos serviços prestados por aplicativos. Neste ensaio, abordamos as implicações do trabalho dos entregadores por aplicativo no âmbito do ODS 8 Crescimento econômico e trabalho decente. Do discurso de empreendedorismo, consumo consciente à falta de direitos trabalhistas e baixa remuneração, analisa-se o trabalho precarizado na pandemia à luz das transformações nas relações de trabalho no Brasil, o aprofundamento da crise econômica e desemprego, o processo de uberização e os impactos para trabalhadores e empresas de serviços por aplicativos. Ao final, são apontadas algumas iniciativas de reação dos trabalhadores em torno de movimentos de valorização do trabalhador e união por reivindicação de direitos.

O cenário de acesso facilitado ao crédito, aliado a uma desinformação sobre finanças pessoais são fatores estudados como possíveis ensejadores do endividamento pessoal. Diante disso, o trabalho verifica a relação existente entre o nível de educação financeira e o grau de endividamento dos servidores da Universidade Federal de Ceará (UFC).A seguinte pesquisa descritiva objetiva estudar as características educacionais, renda, idade, sexo, socioeconômicos e demográficos dos servidores. Sendo um levantamento ou survey e bibliográfica.Constatou-se com base na amostra que um maior conhecimento em finanças pessoais está associado a menores índices de endividamento, onde em maioria as mulheres obtiveram piores níveis de endividamento do que homens. Percebeu-se uma maior frequência de endividamento na faixa etária de 31 a 55 anos. A renda e a escolaridade não apresentaram uma relação bem definida com o endividamento. Esta pesquisa contribui para aprofundar o debate sobre a relação educação financeira e endividamento.
