Development of Perineuronal Nets during Ontogeny Correlates with Sensorimotor Vocal Learning in Canaries
Authors: Cornez Gilles , Collignon Clémentine , Müller Wendt , Cornil Charlotte A. , Ball Gregory F. , Balthazart Jacques
Published: March 2020

Songbirds are a powerful model to study vocal learning given that aspects of the underlying behavioral and neurobiological mechanisms are analogous in many ways to mechanisms involved in speech learning. Perineuronal nets (PNNs) represent one of the mechanisms controlling the closing of sensitive periods for vocal learning in the songbird brain. In zebra finches, PNN develop around parvalbumin (PV)-expressing interneurons in selected song control nuclei during ontogeny and their development is delayed if juveniles are deprived of a tutor. However, song learning in zebra finches takes place during a relatively short period of development, and it is difficult to determine whether PNN development correlates with the end of the sensory or the sensorimotor learning period. Canaries have a longer period of sensorimotor vocal learning, spanning over their first year of life so that it should be easier to test whether PNN development correlates with the end of sensory or sensorimotor vocal learning. Here, we quantified PNN around PV-interneurons in the brain of male canaries from hatching until the first breeding season and analyzed in parallel the development of their song. PNN development around PV-interneurons specifically took place and their number reached its maximum around the end of the sensorimotor learning stage, well after the end of sensory vocal learning, and correlated with song development. This suggests that PNN are specifically involved in the termination of the sensitive period for sensorimotor vocal learning.

In plant–pathogen relations, disease symptoms arise from the interaction of the host and pathogen genomes. Host–pathogen functional gene interactions are well described, whereas little is known about how the pathogen genetic variation modulates both organisms’ transcriptomes. To model and generate hypotheses on a generalist pathogen control of gene expression regulation, we used the Arabidopsis thaliana–Botrytis cinerea pathosystem and the genetic diversity of a collection of 96 B. cinerea isolates. We performed expression-based genome-wide association (eGWA) for each of 23,947 measurable transcripts in Arabidopsis (host), and 9267 measurable transcripts in B. cinerea (pathogen). Unlike other eGWA studies, we detected a relative absence of locally acting expression quantitative trait loci (cis-eQTL), partly caused by structural variants and allelic heterogeneity hindering their identification. This study identified several distantly acting trans-eQTL linked to eQTL hotspots dispersed across Botrytis genome that altered only Botrytis transcripts, only Arabidopsis transcripts, or transcripts from both species. Gene membership in the trans-eQTL hotspots suggests links between gene expression regulation and both known and novel virulence mechanisms in this pathosystem. Genes annotated to these hotspots provide potential targets for blocking manipulation of the host response by this ubiquitous generalist necrotrophic pathogen.

Studies focusing on obesity and asthma frequently consider the weight at a given time; thus, modeling pathways through lifetime overweight may contribute to elucidate temporal aspects in this relationship. This study modeled the pathways in the association of lifetime overweight with asthma in adult life, using data from the 1978/1979 Birth Cohort, Ribeirão Preto, São Paulo, Brazil (n = 2,063) at birth (baseline), school age (9/11 years) and adult age (23/25 years). A theoretical model was proposed to explore the effects of lifetime overweight on asthma in adult life analyzed by structural equation modeling. Parental obesity (SC - standardized coefficenttotal = 0.211, p < 0.001; SCdirect = 0.115, p = 0.007) and overweight at school age (SCtotal = 0.565, p < 0.0001; SCdirect = 0.565, p < 0.0001) were associated with overweight in adult life. Parental obesity (SCdirect = 0.105, p = 0.047) and nutritional status at birth (SCtotal = -0.124, p = 0.009; SCdirect = -0.131, p = 0.007) were associated with asthma in adult life. A higher “current adult socieconomic situation” was inversely associated to overweight (SCdirect = -0.171, p = 0.020) and to asthma in adult life (SCtotal = -0.179, p = 0.041; SCdirect = -0.182, p = 0.039). Parental obesity showed a transgenerational effect in weight, triggering to childhood and adulthood overweight. Parallel to underweight at birth, parental obesity was also a risk to asthma in adult life. While, the socioeconomic status in adult life protected from both, overweight and asthma.

Resumo: O Brasil vem instituindo políticas de prevenção e controle da obesidade por meio do Sistema Único de Saúde, e o estudo analisou as características dos “modelos assistenciais” propostos e referidos por profissionais da atenção básica no Estado do Rio de Janeiro. Os métodos incluíram entrevistas e grupos focais com profissionais e gestores da atenção básica e das Áreas Técnicas de Alimentação e Nutrição (ATAN) dos 92 municípios do Rio de Janeiro, e análise documental de normativas federais e estaduais. A análise foi norteada pelas dimensões organizativa e técnico assistencial, e considerou os princípios da atenção integral em saúde. Os principais desafios referidos pelos profissionais estão relacionados com: a adesão aos processos terapêuticos e consequente sentimento de frustração e impotência; a atuação em equipe multiprofissional; e a constatação de despreparo para lidar com a complexidade do processo saúde/doença relacionado com a obesidade. Alguns princípios e diretrizes pautados nos documentos de políticas governamentais são estratégicos para enfrentar esses desafios, especialmente: a corresponsabilização entre profissional e usuário, pois pode contribuir para evitar os extremos da culpabilização e/ou vitimização; a valorização de outros ganhos para além da perda de peso, que pode ressignificar a concepção de adesão ao tratamento; a atuação multiprofissional para que se desenvolva uma compreensão contextualizada do processo saúde/doença e seus múltiplos condicionantes, e para que os profissionais consigam lidar com os seus próprios sentimentos e estigmas em relação à pessoa com obesidade.

Objetiva-se descrever as consequências no aleitamento e na alimentação que terão as crianças órfãs menores de cinco anos em decorrência da morte materna, aplicando-se softwares livres de mineração de texto. Estudo transversal com base em artigos publicados nos repositórios PubMed e BIREME nos temas de morte materna e crianças órfãs. Foram selecionados dez artigos publicados entre 2005 e 2015, de acesso livre, nos quais foram lidos apenas o título ou o resumo e que cumpriam com os critérios. Os arquivos de texto definiram o corpus para análise de conteúdo semiestruturado. Palavras-chave foram incluídas para a mineração. A análise do corpus foi feita com TagCrowd e Textalyser para encontrar os termos mais e menos frequentes, AntConc e Voyant Tools, para extrair palavras-chave na análise de contexto. Foram analisadas 67.642 palavras em dez textos semiestruturados. Os termos CHILDREN (827) e DEATH (821) foram os mais frequentes, e os menos frequentes foram BREASTFEEDING (10) e NUTRITION (4). Foram encontradas 44 concordâncias para o termo raiz BREAST* e 25 para a palavra NUTRITION em orações como: “crianças órfãs têm o aumento de risco de mortalidade por falta de amamentação, e são mais susceptíveis às infecções”. As sentenças de concordância apontam que a mudança no aleitamento materno conduz a uma nutrição pobre, o que deixa o recém-nascido exposto a infecções, aumentando o risco de morte. O processamento de texto com as ferramentas livres foi rápido e permitiu extrair informações úteis e compreensíveis; a análise dos dez artigos mostrou as consequências na alimentação da criança após a morte materna, tendo efeito na morbidade e mortalidade infantil.

Published: March 2020

ABSTRACT: Brazilian poultry industry generates large amounts of organic waste, such as chicken litter, which is often used in agriculture. Among the bacteria present in organic fertilizer are members of the Enterobacteriaceae family, such as Escherichia coli. The aim of this study was to analyze the profile of virulence factors and antimicrobial resistance of E. coli isolates from avian organic fertilizer. A total of 47 E. coli strains were tested through Polymerase chain reaction to detect virulence genes (hlyF, iss, ompT, iutA and iroN). Fourteen antimicrobials were used to test antimicrobial susceptibility in the strains. Genes characteristic of Avian Pathogenic E. coli (APEC) were reported among the strains, with the hlyF, iss and ompT genes being the most prevalent. The isolates showed high resistance (˃50%) to tetracycline, gentamicin, cefotaxime, nitrofurantoin, trimethoprim-sulfamethoxazole and ampicillin. Multidrug resistance was reported in a great number of strains (>70%). The results showed the presence of APEC cells with virulence genes and antimicrobial resistance after 15 days of the windrowing process in poultry houses, it means this process should be improved to eliminate these cells.

Published: March 2020

ABSTRACT: The increasing use of Vernonia condensata Baker highlights the importance of developing strategies to reduce the impact of exploitation on nature reserves. The aim of this study was to establish a micropropagation protocol to produce homogenous plants with high phytosanitary quality. Apical, nodal, and internodal segments of plants grown in the field were used for in vitro growth. The segments were disinfected in sodium hypochlorite solution (1.0 and 2.0%) for 15 and 30 minutes and then transferred to Petri dishes containing MS culture medium for 30 days. A completely randomized factorial experiment (3 x 2 x 2) with five replicates was designed. After this period, a completely randomized in vitro multiplication experiment was carried out with six treatments (BAP - 0.0; 0.5; 1.0; 1.5; 2.0; 2.5 mg L-1) and six replicates. The shoots obtained in the best treatment were transferred to flasks with rooting medium (MS, MS/2 or MS/4). The experiment was completely randomized with 12 replicates. Microplants were acclimatized in polyethylene terephthalate (PET) bottles filled with autoclaved topsoil. Our results showed that 40.0% of the nodal segments (immersed in 1.0% sodium hypochlorite for 30 minutes) were adequately disinfected and survived. In the in vitro multiplication experiment, the 0.5 mg L-1 concentration of BAP yielded the highest number of shoots and the best vegetative growth. With regard to the assessed characteristics, MS/4 was the best rooting medium, with 100% survival during acclimatization. This study showed that V. condensata in vitro culture might produce 32,000 seedlings in 7 months.

ABSTRACT: Response surface methodology was used to determine optimum conditions for extraction of protein from pumpkin seed meal. A central composite rotational design (CCRD) including independent variables such, pH and sodium trimetaphosphate (STMP) content was used. Maximum yield was obtained at a central point of CCRD, with STMP content and pH of 4% and 4.5, respectively. These conditions resulted in protein yield of 50.04 g of soluble protein from extract/100 g pumpkin seed. The optimization of pH and STMP content allowed obtaining a product with a high protein concentration (62.56 g 100 g-1), digestibility (62.03 g 100 g-1) and concentration of essential amino acids (27.26 g 100 g-1). Regarding the polyphenols concentration, phosphorylated protein concentrate from pumpkin seed and the pumpkin seed meal presented 13.11 g 100 g-1 and 23.19 g 100 g-1, respectively. The adequacy of the model was confirmed by extracting the protein under optimum values. These results help in designing the process of optimal protein extraction from pumpkin seeds.
Effects of storage on vis-NIR-SWIR reflectance spectra of Mombasa grass leaf samples

Published: March 2020

ABSTRACT: Vis-NIR-SWIR reflectance spectra of leaf samples, collected in the laboratory, allow the calibration of predictive models to quantify their physicochemical attributes in a practical manner and without producing chemical residues. This technique should enable the development of management strategies for intensification of pasture use. However, spectral analysis performed in the laboratory may be affected by the deterioration of plant material during transport from the field to the lab, so storage methods are necessary. This research aimed to evaluate the effects of different storage methods on the spectral response of Mombasa grass leaves. Three methods were evaluated: (i) artificially refrigerated environment, (ii) humid environment, and (iii) without microenvironment control. These methods were tested in five different storage times: 2 hours, 4 hours, 8 hours, 24 hours and 48 hours. The spectral behavior of the leaves still inserted in the plant was used as a quality reference. Results showed notable changes at the earliest storage time for the treatment without microenvironment control. Both methods with microenvironment control stabilized the occurrence of spectral changes over 48 hours of the samples storage, thus both were suggested for this species.

Published: March 2020

ABSTRACT: The aim of this paper was to describe the clinical and sonographic findings of partial tear at the musculotendinous junction of the proximal long digital extensor tendon during the acute phase and one year after initial presentation. The dog presented with acute, moderate weight-bearing lameness of the right hind limb. During an orthopedic examination of the stifle, the dog expressed pain on extension and flexion of the right knee. Under general anesthesia, no instability was evident. Radiographic images suggested the presence of joint effusion in the right stifle. Ultrasonography revealed that the long digital extensor tendon was hyperechoic, surrounded by an anechoic effusion, and the muscle fibers were disorganized and interspersed with anechoic fluid. Clinical outcome was considered good after conservative treatment. The dog was re-evaluated approximately one year after treatment and did not present with any clinical signs.

Published: March 2020

Abstract: Despite the increasing number of Public-Private Partnerships projects, the results have shown little effectiveness and difficulties in several aspects of project management. This study performs a systematic literature review combining bibliometric analysis and content analysis to identify the challenges in managing these projects and techniques to overcome them, highlighting the critical success factors for project management. The results indicate an increasing number of researches in the field, but there is still a lack of systematization of the management tools and absence of critical success factors during the accomplishment of this type of project. This study proposes a systematization of these elements throughout the project cycle, allowing project managers to visualize challenges and techniques to increase the results related to the main success factors of each stage.

ABSTRACT Objective: to describe the motivations that mobilize professors-nurses in the construction of a proposal for the theoretical and methodological basis for the Nursing Process teaching. Method: a Convergent Assistential research, conducted with professors-nurses. Six convergence groups were developed, with triggering questions on the theme. The reports were audio-recorded, validated by the participants and analyzed in the light of the Convergent Assistance Research. Results: there are three thematic approaches: professors' perception of the nurses' professional practices; dissatisfaction with the current health model; and dissatisfaction with the current teaching model. The thematic approaches reveal the motivation to overcome biomedical/cartesian practices in teaching and nursing care, which converges to the development of a proposal with a philosophical, theoretical and methodological framework for the Nursing Process teaching, aligned with the assumptions of the Unified Health System and consistent with health expanded clinic. Conclusion: this study allowed for the expression of concerns and discomforts with the current model of education and health, triggering reflections on the paradigm that guides the field of health teaching and dominates our life in society. The results reveal what is desired in the health scenario, as educating individuals and society, enhancing the perspective of social changes in the health sector, acclaimed and desired politically and socially, basing the development of philosophical, theoretical and methodological proposals for nursing care, consistent with society's current demands.

Published: March 2020

Abstract: Introduction: In recent years, there has been an increase in the number of medical residency programs in all regions of Brazil, only in the last 4 years, from 2014 to 2018, there was an increase from 18,953 general spots offered for the first year of medical residency to 26,094, 37% more, this was also observed in General Surgery Residencies around Brazil. As a result, the number of general surgeons has increased substantially, from 12,430 in 2008 to 34,065 in 2018, an absolute percentage increase of 174%. These new surgeons are bringing with them their theoretical and practical knowledge already updated, regarding new techniques and surgical modalities. In this context, in the last 2 decades, video-assisted surgery has become the choice for numerous procedures in Brazil and in the World, considering its benefits for patients, such as less postoperative hospital stay and less metabolic response to surgical trauma, for example. The current study correlates the data between the increase in the number of spots in medical residency programs, related to the graduation of new surgeons in Brazil, to the increase of videolaparoscopic surgeries in the public health system. Methodology: Review and online analysis of the national electronic public health registry database - DATASUS. The most performed Surgeries in Brazil were chosen for our data analysis. Results: The results were divided into five geographically distributed areas in Brazil. At the end of the current study, the number of video-assisted surgeries increased by 233%, accompanied by a 63% increase in the number of medical residency openings and a 174% absolute increase in the number of new surgeons in Brazil at the same period. Conclusion: The current study showed that the increase in the number of video-assisted surgeries in the country is related to the exponential increase in the number of medical residency spots and, consequently, to the number of new graduated general surgeons. This increase occurs more and more in a context of videolaparoscopic techniques, revealing multiple benefits already recognized for patients. We could conclude, therefore, that the increase in the number of medical residencies in general surgery - which are increasingly teaching videolaparoscopic techniques - has contributed as a complementary factor to the increase in the number of video-assisted surgeries observed in all regions of Brazil.
Lessons Learned from the Student’s Surgery Academic League: Is It Worth It?
Authors: Miranda Luiz Eduardo Correia , Miranda Ana Clara Galindo , Lima Diego Laurentino de , Arraes Ana Karla Alves
Published: March 2020

Abstract: Introduction: One of the great challenges of a medical school curriculum is to offer training in basic surgical techniques, which allows graduates to develop competences to take care of simple cases presented in the primary care level of SUS. In order to approach the problem of the technical-surgical qualification of medical students and taking advantage of the interest raised by students’ leagues, a surgical care project directed at patients with inguinal hernia was proposed and carried out, based on the students’ academic leagues. The aim of this study is to disclose and discuss the results and the academic experience learned from a students’ league in surgical learning. Methods: This report encompasses the three-year experience of an academic league aiming to approach the problem of the technical-surgical qualification of medical students and which takes advantage of the academic leagues among undergraduate medical students. The participants comprised one general surgery professor, one anesthesiologist, and undergraduate medical students interested in the surgical clinic, from the School of Medicine, University of Pernambuco, Recife (PE), Brazil. Results: Twenty-four students were included. Ninety-six patients were submitted to surgery. Two seminars with nine lectures and one workshop on surgical skills were held. One paper entitled “League of Inguinal Hernia Surgery” was presented. We did not observe hernia recurrences; the surgical complications were minimum and small in number. The students showed fast development of surgical, interpersonal, and communication skills. However, this education model included a small number of students and offered heavy competition to the general surgery residents in their first year at the University Hospital. Conclusion: The academic league in surgery allows a rich pedagogical experience, offering the opportunity for human and technical qualification. However, the proposed model has limitations. In our opinion, it does not represent a solution for the flaws and omissions observed in the school’s curricular grid.
Chemical and sensory characterization of corn oil flavoured by citrus
Authors: Hernández Petra Beatriz Navas , Durán Armando Carrasquero
Published: March 2020

Abstract A commercial and refined corn oil was added with fresh lemon and orange fruits to produce corn oil flavoured (COF), which were characterized for their quality parameters, fatty acid profile and concentrations of minor components. The sensory analysis was performed by a panel using the quantitative descriptive analysis and the hedonic score. Results showed that the addition of citrus fruits did not affect the oil quality indices, accomplishing the requirements for commercialization. The biophenols and pigments, initially absent in the refined oil, were detected in COF. The addition of orange or lemon fruits to the corn oil had no effects on oil stability, while the volatile profile in the headspace of flavoured oils showed the presence of several terpenes that were originally absent, among them: limonene; γ-terpinene; α-pinene and β-pinene. The sensory results confirmed that positive attributes and the acceptability of the unflavored corn oil can be improved by increasing amounts of both fruits.
Fortified and freeze-dried kiwi fruit (Actinidia deliciosa): quality and sensory assessment

Published: March 2020

Abstract Kiwi fruit (Actinidia deliciosa) (KF) is one of the best fruits available due to its large amount of nutrients. Despite its many health benefits, there are no previous reports on its preparation in other readily ingestible forms. The objective of the present study was to make a new food product from KF. The KF pulp was fortified and blended with several raw materials (such as rice flour and oat flour) using a stepwise short time addition and mixing methodology since this avoids unwanted biochemical and chemical reactions. The blended and reduced moisture KF paste was freeze-dried on a round silver coated steel plate (RSCSP), supplying the heat of sublimation using a newly designed cubic heater. The freeze-drying (FD) time was 4.5 h and the drying kinetics were studied using four established models. The effective moisture diffusivity (Deff) during FD (at 50 °C) was 1.532 x 10-6 m2/s and the activation energy (E) estimated for the FD was 28.35 kJ/mol. The freeze-dried sample was ground and placed under vacuum to reduce the weathering effects. The quality of the stored product was evaluated using the proximate analysis, physicochemical analysis and a sensory evaluation using a hedonic scale. The raw, fresh KF had a moisture content of 85.07% and the final freeze-dried product one of 3%. The carbohydrate, total sugar, protein, fat, total ash, crude fibre and vitamin C contents of the final product increased by 563%, 400%, 355%, 386%, 672%, 106%, and 117% respectively. Of the 66 panelists, the % consumer acceptances for the different attributes were: sweetness (68.18%), sourness (90.91%), saltiness (100%), bitterness (100%), flavour (95.45%), texture (77.27%) and overall acceptability (81.82%). Using conventional freeze-drying (CFD) for blended KF pulp without fortification, with the same RSCSP and the same cubic heater for sublimation, the drying time was found to be 7 h to reach the same final moisture content of 3%.

Published: March 2020

ABSTRACT Objective The aim of this study was to evaluate the in situ hardness, compressive strength and resilience of soft lining materials used in total removable prostheses in different time intervals Methods total of 48 rectangular test specimens (10 x 3 x 2 mm) were fabricated of each of the polyvinylsiloxane-based soft liner (Mucopren Soft) and acrylic resin-based material (Trusoft), which were placed on total removable prostheses bases of 12 volunteers (n = 12). The hardness (Shore A), compressive strength (in MPa) and resilience (in Kgf/cm2) were evaluated in different time intervals: 0, 7, 30 and 60 days, at three different locations of the specimens surface. Results The two-way ANOVA and Tukey test showed that the polyvinylsiloxane-based soft liner presented higher hardness values (p = 0.0113) and higher compressive strength (p=0.0252) than the acrylic resin-based material at immediate and 7 days evaluations. The polyvinylsiloxane-based soft liner presented higher resilience values than the acrylic resin-based material at all times (p = 0.0133). Hardness and compressive strength were similar for both materials at 30 and 60 days evaluations. Conclusions For both materials,there was a tendency for an increase of hardness, compressive strength and resilience over time, influenced by the composition of the tissue conditioner. The polyvinylsiloxane-based soft liner presented higher hardness, compressive strength and resilience than the acrylic resin-based material, specially considering a long-term evaluation up to 60 days.

ABSTRACT Dentoalveolar trauma is a severe traumatic injury involving alveolar bone and dental structures. Like any trauma, it can leave irreparable sequelae and even cause tooth loss. The aim of this study is to report on the case of a dentoalveolar trauma in a 10-year-old male patient and the treatment performed with 12-month follow-up. The child had lateral luxation and displacement of teeth 11 and 21 in labial direction after a fall from his own height. The patient was examined at a hospital, received medication and was referred to a dental clinic. At the dental office, the teeth were repositioned, as well as received endodontic treatment and dental reanatomization. Two months after the trauma, root resorption was observed externally, which remained stable for 12 months. It was concluded that post-trauma treatment should be immediate and that follow-up sessions should be done carefully to minimize sequelae and to receive better prognosis.

Published: March 2020

Abstract The aim of the study was to identify students’ self-regulation through learning strategies adoption in connection with motivation. A sample of 212 freshmen students answered a Likert-type questionnaire with the aim to assess learning strategies, mastery achievement goal, extrinsic goals, procrastination, and discipline valuation. Strategy use consisted in a specific task of writing a text. A person-centered approach was adopted according to the statistical data and four self-regulation clusters were identified, namely, highly self-regulated students, low regulation students, and two clusters with mixed scores. Through variance analysis mastery achievement goal appeared significantly associated only with thehighly self-regulated students cluster. Results were discussed in the framework of a self-regulated learning model and achievement goals theory. Finally, future investigations on other specific learning activities were proposed.
The impact of extreme weather events on community risk planning and management: the case of San Juan, Puerto Rico after hurricane Maria
Authors: Santiago Luis , Flores David , Hong Chang-Yu
Published: March 2020

Abstract Top-down technical or engineered solutions to deal with flood control such as channelization are increasingly unaffordable. We explored how community leaders’ frame the concept of risk, particularly due to flooding, and documented bottom-up rather than top-down solutions within the context of Hurricane Maria and the current financial crisis. This research aimed to interview environmental conservation organizational leaders to assess the broader question of what makes San Juan livable, and the role that flooding risk management plays in defining livability. Their perception of bottom-up approaches for flood control, including the role of green infrastructure, is of particular interest given the infeasibility of current engineered measures and their history of short term local coping strategies. Our research team frames the research using structural versus non-structural solutions to explore to what extent community leaders draw upon green visions of the city or emphasize transitioning towards strategies more closely aligned with ecological processes and functions. The research results help to inform current efforts of local community engagement about alternative solutions to channelization and other urban flood management measures.
TEORIA CRÍTICA NAS MARGENSUm diálogo entre marxismo e pós-colonialismo
Authors: Borba Pedro dos Santos de , Benzaquen Guilherme Figueredo
Published: March 2020

O objetivo do artigo é revisitar o debate sobre marxismo e pós-colonialismo, com o intuito de desbravar um terreno construtivo de crítica a partir do conflito. O percurso do argumento está dividido em três etapas. A primeira enfatiza duas facetas constitutivas do pensamento de Marx: uma de traços nitidamente eurocêntricos, que refraseia temas do iluminismo e da filosofia da história hegeliana; outra que enseja um olhar menos teleológico sobre as periferias, o colonialismo europeu e as perspectivas de emancipação humana. A segunda aborda o pós-colonialismo como um heterogêneo movimento de teoria crítica periférica, separando também duas ênfases: uma vertente mais fortemente desconstrutivista, que tende a rejeitar o marxismo como uma dentre as metanarrativas da modernidade; outra que se desmembra e desenvolve em estreito diálogo com as lutas anti-imperialistas do século XX. A parte final aponta as potencialidades de reconstrução conceitual entre um marxismo antieurocêntrico e um pós-colonialismo que não se exime da crítica às grandes estruturas de dominação da modernidade.
O MERCADO FINANCEIRO CHEGA À SALA DE AULA: EDUCAÇÃO FINANCEIRA COMO POLÍTICA PÚBLICA NO BRASIL
Authors: Cunha Márcia Pereira
Published: March 2020

RESUMO O objetivo do artigo é descrever e analisar a implementação daEstratégia Nacional de Educação Financeira no Brasil, destacando dois aspectos de seu desenho institucional: a simbiose entre instituições públicas e do mercado financeiro e sua localização no interior de uma rede transnacional promotora da Educação Financeira em diversos países. Defende-se que essas características beneficiam a introdução, no ambiente escolar, de conteúdos e valores cujos objetivos pedagógicos associam-se a um projeto de sociedade pouco nítido e não discutido pelos atores sociais interessados. Recorre-se a documentos, legislação e publicações produzidas pelos órgãos promotores desta experiência, de forma a reconstituir suas bases e caracterizar uma forma nova e recente de incidência sobre a educação no Brasil.

Abstract Objective: The main goal was the peer evaluation of the effectiveness of a health education intervention, also seeking the characterization of violent behaviors experienced by teens in intimate relationships. Method: A pretest-posttest quasi-experimental study was performed with a non-probabilistic sample of 197 teens of both genders without control group. The intervention performed consisted of one peer-run forum theater session about intimate violence in dating relationships of teens. Results: Boys reported being both victims and perpetrators of violent behaviors more frequently than girls. The sample reported more behaviors associated with victimization than perpetration. Girls showed a higher level of knowledge on the topic and this knowledge increased after the intervention. Conclusion: Psychological violence is highly prevalent in dating relationships, particularly in cases of victimization. It seems essential to understand and act upon adolescents’ perceptions about what violent behavior is. This study confirmed the effectiveness of health education in acquiring knowledge on this topic.

Authors: Kalinina Irina , Maksimova Polina
Published: March 2020

Nowadays, due to the insufficiently developed theoretical background of gallery business, gallery owners mainly rely on their intuition, analysis of the art market, and numerous sketchy theoretical works and tips. The article presents a comparative analysis and characteristics of the art galleries of the city of Irkutsk, not mentioned previously in the literature. A list of resources necessary for the formation and promotion of attractiveness of art galleries for tourists has been developed. It was created on the basis of the analysis of the activities of Russian and foreign galleries in terms of their tourism attractiveness and cooperation with tourist companies. At the same time, it is mentioned that measures aimed at developing of the tourism attractiveness of the gallery, which are quite often commercial by their nature, should promote the brand of the territory where the gallery is located, preserving its uniqueness. They should in no way turn the art gallery into a gift shop selling art souvenirs.

Published: March 2020

OBJETIVO: compreender os saberes dos enfermeiros atuantes na unidade de clínica médica adulto de um hospital de ensino bem como os seus desafios e perspectivas sobre a Sistematização da Assistência de Enfermagem. MÉTODO: estudo de abordagem qualitativa, utilizando-se da análise de conteúdo de nove entrevistas com enfermeiros de um hospital público de ensino de grande porte. RESULTADOS: os enfermeiros, mesmo reconhecendo a importância da sistematização da assistência de enfermagem, apresentam um conhecimento superficial do tema; vivem desafiados pelas precárias condições de trabalho institucionais, somadas a sobrecarga de atividades, o que dificulta a implementação e continuidade do cuidado sistematizado; e, implementar e continuar o cuidado sistematizado constitui uma reafirmação do cunho científico da profissão bem como estratégia para melhora do cuidado prestado. CONCLUSÃO: a sistematização da assistência de enfermagem no cotidiano do enfermeiro perpassa por subsídios profissionais e institucionais, sendo o último o de maior impacto, o que desvela um cenário dificultador do cuidado de enfermagem que deve ser pensado e discutido para o avanço da qualidade assistencial.

Authors: Низомутдинов Борис Абдуллохонович , Тропников Александр Сергоеевич
Published: March 2020

Электронное участие становится все более важным фактором развития успешных отношений между государством и обществом. Существуют различные способы электронного участия. Один из них - обращение к власти через интернет-приемную. В статье представлены результаты пилотного исследования, предполагающего контент-анализ обращений граждан. Авторы собрали список интернет-приемных, на которых находятся в открытом доступе тексты обращений — это обращение граждан с ответами. Из общего списка было отобрано 5 площадок из разных регионов с максимальным количеством обращений, на основе которых проведен контент-анализ опубликованных заявок. Результаты представленного исследования могут быть полезны для разработки методологии и критериев оценки электронного участия в России.
Тенденции и способы технологизации труда в российской экономике (на примере анализа вакансий в Сибирском ФО)
Authors: Сизова Ирина Леонидовна , Бакаев Максим Александрович
Published: March 2020

В статье анализируются разделы актуальных вакансий, размещенных на сайтах HeadH u nter, Общероссийская база вакансий («Труд всем»), Зарплата.ру и др., с локализацией в Сибирском ФО, с точки зрения трудовых обязанностей и цифровых знаний и навыков, требуемых в современной экономике. Авторы приходят к следующим выводам. В настоящее время работник должен все больше учиться работать в условиях многозадачности, приобретать разнообразные навыки и знания, часто не связанные напрямую с его профессиональной подготовкой. В этом процессе, все больше трудовых задач исполняются при помощи цифровых средств, к которым относятся не только универсальные и элементарные (гаджеты, офисное ПО или социальные сети), но и специализированные: электронная коммерция, ПО управления предприятием, технологические программы и САПР, и др. В условиях широкого использования цифровой среды российскими предприятиями, современный работник должен быть готов к их освоению и перманентному обновлению.
When Alphabet Inc. Plans Toronto’s Waterfront: New Post-Political Modes of Urban Governance
Authors: Carr Constance , Hesse Markus
Published: March 2020

‘Smart cities’ has become a hegemonic concept in urban discourses, despite substantial criticism presented by scholarly research and activism. The aim of this research was to understand what happens when one of the big digital corporations enters the field of real estate and land use development and urban planning, how existing institutions respond to this, and how modes of urban governance are affected. Alphabet Inc.’s plans for Toronto’s waterfront provided insights into these questions. Our investigations traced a complex web of place-making practices that involved all levels of government, the general public, and networks of actors throughout the private sector. Methodologically, the discourse was reconstructed with local fieldwork, interviews with key actors, participating in tours and public meetings, and secondary sources. It was found that Alphabet Inc.’s plan to build a world-class digital city contained some lessons for urban studies and urban planning practice. First, Alphabet Inc.’s plans, which unfolded amidst initiatives to expand the knowledge economy, confirmed concerns that the trajectory of neoliberal, market-driven land use and speculation along the waterfront remains unchanged. Second, digital infrastructures are potentially a Trojan Horse. Third, it was seen that municipalities and their modes of urban planning are vulnerable to the political economic manoeuvrings of large corporate power. Fourth, Alphabet Inc. operates as a post-political package driven by a new coalition of politics, where the smart city is sold as a neutral technology. The controversies surrounding the project, however, stirred a civic discourse that might signal a return of the political.
