Pseudorabies virus (PRV) UL2 (pUL2) is a multifunctional protein, which is homologous with herpes simplex virus 1 early protein UL2 (hUL2) and crucial for the viral propagation. Yet, how pUL2 executes its roles in the viral life cycle remain inadequately understood. In order to uncover its effect on the procedure of PRV infection, investigation was performed to examine the subcellular distribution of pUL2 and establish its trafficking mechanism. In the present study, enhanced yellow fluorescent protein or Myc tag fused pUL2 was transiently overexpressed in transfected cells and exhibited an absolutely nuclear accumulation without the existence of other PRV proteins. Additionally, the nuclear trafficking of pUL2 was proved to rely on Ran-, transportin-1, importin β1, importin α1, α3 and α5. Accordingly, these data will benefit the knowledge of pUL2-mediated biological effects in PRV infection cycle.
Platelets as a ‘natural factory’ for growth factor production that sustains normal (and pathological) cell biology

Published: October 2019

Platelets have attracted substantial attention in the current decade owing to their unexpected pleiotropic properties and conflicted functions. In fact, platelets participate in both health (hemostasis) and disease (thrombotic diseases). Much of the plasticity of platelets comes from the fact that platelets are the reservoir and the ‘natural factory’ of growth factors (GFs), with pivotal functions in wound repair and tissue regeneration. By combining the platelets’ plasticity and biotechnological processes, PlateInnove Biotechnology optimized the production of GFs in nanoparticle biointerfacing by platelet content, which opens an avenue of possibilities.
Proteasomes: unfoldase-assisted protein degradation machines
Authors: Majumder Parijat , Baumeister Wolfgang
Published: October 2019

Proteasomes are the principal molecular machines for the regulated degradation of intracellular proteins. These self-compartmentalized macromolecular assemblies selectively degrade misfolded, mistranslated, damaged or otherwise unwanted proteins, and play a pivotal role in the maintenance of cellular proteostasis, in stress response, and numerous other processes of vital importance. Whereas the molecular architecture of the proteasome core particle (CP) is universally conserved, the unfoldase modules vary in overall structure, subunit complexity, and regulatory principles. Proteasomal unfoldases are AAA+ ATPases (ATPases associated with a variety of cellular activities) that unfold protein substrates, and translocate them into the CP for degradation. In this review, we summarize the current state of knowledge about proteasome – unfoldase systems in bacteria, archaea, and eukaryotes, the three domains of life.

Published: October 2019

Mitragyna speciosa, commonly known as Ketum or Biak in Malaysia and Kratom in Thailand, is a native plant to Southeast Asia and has various pharmacological benefits. Mitragynine (MG) is the principal alkaloid found in the leaves of Mitragyna speciosa and has been reported to be responsible for the plant’s therapeutic actions. Traditionally, local communities use Kratom preparations for relief from different types of pain. The potential analgesic effects of MG using rodent models have been reported in literatures. We have reviewed the published analgesic and pharmacokinetic studies and all of these findings showed the routes of drug administration, doses employed, and type of vehicles used to solubilize the drug, varied considerably; hence this posted difficulties in predicting the drug’s pharmacokinetic-response relationship. A rational approach is warranted for accurate prediction of dose-response relationship; as this is essential for the development of MG as an alternative medicinal drug for pain management. PKPD modeling would serve as a better method to understand the dose-response relationship in future MG preclinical and clinical studies.

Published: October 2019

Semiconductor nanowires (NW) hold great promise for micro/nanolasers owing to their naturally formed resonant microcavity, tightly confined electromagnetic field, and outstanding capability of integration with planar waveguide for on-chip optoelectronic applications. However, constrained by the optical diffraction limit, the dimension of semiconductor lasers cannot be smaller than half the optical wavelength in free space, typically several hundreds of nanometers. Semiconductor NW plasmonic lasers provide a solution to break this limitation and realize deep sub-wavelength light sources. In this review, we summarize the advances of semiconductor NW plasmonic lasers since their first demonstration in 2009. First of all, we briefly look into the fabrication and physical/chemical properties of semiconductor NWs. Next, we discuss the fundamentals of surface plasmons as well as the recent progress in semiconductor NW plasmonic lasers from the aspects of multicolor realization, threshold reduction, ultrafast modulation, and electrically driven operations, along with their applications in sensing and integrated optics. Finally, we provide insights into bright perspectives and remaining challenges.

Published: October 2019

Bismuth sulfide (Bi2S3) is a binary chalcogenide semiconductor compound that has received much attention in optoelectronic devices because of its stratified structure. In this work we showed that the two-dimensional (2D) Bi2S3 shows strong nonlinearity using spatial self-phase modulation and that the all-optical photonic devices, e.g. the all-optical switches and all-optical diodes, have been demonstrated experimentally by observing the nonlinear behavior of the diffraction rings. In addition, an all-optical diode is designed in this work using combined structure with 2D Bi2S3/SnS2 nanosheet by taking advantage of the reverse saturated absorption of 2D SnS2 and saturated absorption of 2D Bi2S3. Nonreciprocal light propagation has been achieved with different incident wavelength and a variety of incident intensities. Those characteristics make 2D Bi2S3 a potential candidate for the next generation nonreciprocal all-optical device.
Surface characterization of paper and paperboard using a stylus contact method
Authors: Ko Young Chan , Melani Lili , Park Na Young , Kim Hyoung Jin
Published: October 2019

Surface characterization is important and has many applications in the paper industry. Surface characterization requires both surface roughness and surface friction. The relationship between the two has not been fully established for paper and paperboard. It has been a common practice that only the average property and the standard deviation with the coefficient of variation (COV) are reported for surface roughness and friction measurements. This practice, however, provides few information on surface structure and can lead to wrong judgments because two samples having the same average and the COV can have different physical properties. To avoid such mistake, a new surface characterization method has been developed. To this end, surface roughness- and friction-profiles have been obtained using a latest version of Kawabata surface tester (Model: KES-SESRU, Kato Tech, Kyoto Japan). This new version uses the same stylus for both measuring surface roughness and friction under the same operating conditions. It was found that a correlation between the surface roughness and surface friction was very low. This indicates that they should be independent of each other. Therefore, both should be determined for surface characterization.
Green routes to silicon-based materials and their environmental implications
Authors: Furgal Joseph C. , Lenora Chamika U.
Published: October 2019

The “greening” of silicon chemistry is fundamentally important for the future of the field. Traditional methods used to make silicon-based materials rely on carbon rich processes that are highly energy intensive, cause pollution, and are unsustainable. Researchers have taken up the challenge of developing new chemistries to circumvent the difficulties associated with traditional silicon material synthesis. Most of this work has been in the conversion of the “green” carbon neutral biogenic silica source rice hull ash (RHA, ~85 % silica) into useful silicon building blocks such as silica’s, silicon, and alkoxysilanes by using the inherently higher surface area and reactivity of RHA to sidestep the low reactivity of mined silica sources. This is a review of the work that has been done in the area of developing more environmentally benign methods for the synthesis and use of silicon containing materials to eliminate the negative impact on the environment.

Authors: Abdollahpour Sedigheh , Heidarian Miri Hamid , Khadivzadeh Talat
Published: October 2019

Background: Improving the maternal health is one of the world’s most challenging problems. Despite significant movements over the past decades, maternal health has been still considered as a central goal for sustainable development. Maternal near miss (MNM) cases experience long-term physical and psychological effects. To present a clear portrait of the current situation, we performed a systematic review and meta-analysis with the purpose to assess the worldwide prevalence of MNM. Methods: We conducted a systematic review on PubMed, Scopus and Web of Science electronic databases to find published papers in English, before March 2019 and regardless of the type of study. We, then, assessed the prevalence of MNM according to the World Health Organization(WHO) criteria. Finally, 49 papers were included in the study. Random effects meta-analysis was used to pool the available prevalence. The quality of studies was also evaluated. Results: The weighted pooled worldwide prevalence of MNM, was 18.67/1000 (95% CI: 16.28-21.06). Heterogeneity was explored using subgroup analyses based on the continent and the country. We used meta-regression of MNM on MD which resulted in adjusted R-squared as78.88%. Conclusion: The prevalence of MNM was considerable. Low- and middle-income countries should develop systematic approaches to improve quality of care in the facilities and to reducethe risk of MNM events, with the hope to women’s health.

Published: October 2019

Background: Due to inconsistent evidence regarding the potential role of vitamin D on lipid profile and sirtuin 1 (SIRT-1), this study was designed to investigate the effect of vitamin D supplementation in combination with weight loss diet on lipid profile and SIRT-1 in obese subjects with vitamin D deficiency. Methods: Forty-four obese subjects with vitamin D deficiency were randomly assigned in a randomized clinical trial to receive either a weight reduction diet supplemented with 50000IU vitamin D3 pearl (n = 22) or placebo (n = 22) once weekly for 12 weeks. Changes in total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG) and low high density lipoprotein cholesterol (HDL-C) and SIRT-1 were the primary outcomes. Secondary outcomes were changes in body mass index (BMI), 25(OH) D and parathyroid hormone (PTH). Physical activity and dietary intakes were also assessed. Results: During the intervention, PTH (mean difference, -33.36; 95% CI: -49.15 to -17.57;P<0.001) and LDL-C (mean difference, -15.91; 95% CI: -21.76 to -10.07; P<0.001) decreased and 25(OH) D (mean difference, 36.44; 95% CI: 29.05 to 43.83; P<0.001) increased significantly in the vitamin D group. BMI (mean differences: -2.40; 95% CI: [-2.92 to-1.88] in vitamin D group and mean differences: -1.90; 95% CI [-6.58 to -3.01] in placebo group, P<0.05 for both groups), TC (mean difference,-21.31; 95% CI: -27.24 to -15.38; P<0.001 in vitamin D group and mean difference, -12.54; 95% CI: -19.02 to -6.06; P<0.001 in placebo group) and TG (mean difference,-21.31; 95% CI: -27.24 to -15.38; P<0.001in vitamin D group and mean difference, -12.54; 95% CI: -19.02 to -6.06; P<0.001 in placebo group) decreased and SIRT-1(mean difference, 3.95; 95% CI: 1.18 to 6.73; P=0.007in vitamin D group and mean difference,1.91; 95% CI: 0.31 to 3.63 in placebo group, P=0.022) increase significantly in both group. At end of the study, 25(OH) D and PTH showed significant differences in between-group analyses(P<0.05). No significant difference was detected for HDL-C in within and between groups. Conclusion: This study gives no support for any beneficial effect of vitamin D supplementation on lipid profile and SIRT-1 in obese subjects with vitamin D deficiency.

Background: The epidemiology of human brucellosis has drastically changed in recent years. This study aims to assess trend in brucellosis in the Oskou county, East Azerbaijan, Iran. Methods: This cross-sectional study was conducted on all confirmed brucellosis cases over the period between 2007 and 2016 in Oskuo county. We use crude incidence rate (CIR) per100000 persons and carried out Joinpoint regression analysis to describe brucellosis trend over the study period. Also, we used ARIMA model to predict trend and number of new brucellosis cases for the coming years. Results: More than 90% (92.5%; 95% CI: 89.9-95.1) of brucellosis cases were in rural areas over the study period. In recorded cases, 60.5% (95% CI: 55.6-65.4) of total cases were men and 39.5% (95% CI: 34.6-44.4) of total cases were women. The mean age of men was 33.85(SD=19.72) years and the mean age of women was 35.88 (SD=17.26) years old. Majority of brucellosis cases occurred in spring. CIRs for the rural and urban areas were 47.62 to132.20 and zero to 18.55, respectively. The CIR for rural area had decreasing trend to 2011 and increasing for 2011-2017. Conclusion: Based-on time series analysis, the number of new cases in the future years has fixed trend and the most number of incident cases will be occurred between third to fifth months in each years.
The Interaction of Organizational Capabilities and Individual Competences for Open Innovation in Small and Medium Organizations
Authors: Pranciulytė-Bagdžiūnienė Ilma , Petraitė Monika
Published: October 2019

Open innovation serves as a principal paradigm for success in diverse and dynamic business environments, as it gives the promise of a better-marked acceptance, a higher level of novelty, and managed innovation risks. However, SMEs face a critical challenge in developing open innovation capabilities and establishing new organizational processes that would empower employees to perform in open innovation regimes. We analyze the mediating role of organizational capabilities for employing and facilitating individual competences for innovation performance improvement as based on a survey of 266 SMEs. This study aimed to identify links between organizational capabilities and individual comp etences in AI for innovation performance in SMEs. The results of our study showed that organizational capabilities in AI at the level of organizations play a role as a mediator between competences for AI at the individual level and the progress of innovations. Considering that organizational skills in AI (organizational culture openness, organizational learning and trust, knowledge management systems, etc.) are strong organizational tools that help to increase the efficiency of AI and individual competences (to enhance employee creativity, enhance interaction with partners) as well as management competences (flexibility, ability to work with various professional communities, strategic thinking, etc.). This study partially refutes the assumptions that SMEs can only achieve innovative progress through individual competences in AI. Organizational capabilities in AI are also very important for AI implementation.

Published: October 2019

We present here the first record of Histiotus velatus I. Geoffroy St.-Hilaire, 1824 for the province of Salta, Argentina. Until now, in Argentina, this species was only known from Jujuy, Corrientes, and Misiones provinces. Our record adds a fourth province to the distribution of this species in the country and the second record for the Northwestern Argentina, rising to 39 the number of bat species in Salta. We captured three adult males with mist-nets placed in Parque Nacional El Rey. This site represents one of the last largest continuous blocks of protected forests, within a region affected by the greatest anthropic transformation (e.g. agricultural development, cattle grazing) of northwestern Argentina.
Transport System of the Rostov Agglomeration: Infrastructural Limitations and Directions of Development
Authors: Patrakeeva Olga
Published: October 2019

The sustainable development of regions implies unity and the inclusion of social, economical and spatial subsystems which are supported by means of advanced land use planning and encouraging agglomeration processes as well as developing transport infrastructure. The article describes the results of analyzing the current situation of the transport system in the Rostov agglomeration, its growth prospects by means of implementing major infrastructural projects which are the most important tool for accelerated development and increasing the inflow of investments into the regional economy. Such projects include “Aeropolis” which is being implemented within the territory of Grushevsky settlement adjacent to the Platov airport complex, creating the system of high-speed railway lines “Donskoy express”, “Rostov ring road” project aimed at developing a belt highway encircling Rostov-on-Don. Additionally, it is noted that today one of the key problems of the Rostov agglomeration is a high load of principal transport routes which connect the agglomeration with the regional neighboring suburban areas as well as with the traffic system of Rostov-on-Don. The results of the economic analysis show that the construction of motor ways, carriageway extension, improvement of junctions and crossroads do not encourage economic growth and more likely aggravate the problem of transport network overload. In order to reduce traffic load on roads it is essential to pursue a coordinated city-planning and transport policy intended to enhance the quality of performance of public vehicles, reduce the use of passenger cars. One of the solutions of the transport network load problem in the agglomeration can be the formation of a polycentric agglomeration model which would allow reducing traffic load on the metropolitan city.
Problems and Prospects of Marketing Activity Intensification of Healthcare Organizations in Rostov Region
Authors: Borzenko Kseniya
Published: October 2019

The article focuses on the scientific and practical problem associated with raising and maintaining the competitiveness of healthcare organizations at a high level. The solution of this problem implies creating marketing relations in the sphere of public health and activating marketing of organizations working in this field. This article aims to identify key problems, determine and substantiate prospects for activating marketing activity of healthcare organizations in Rostov region. As a result of the research the author made the conclusion that the key problems of activating marketing activities of healthcare organizations in Rostov region are reduced to the imbalance in the market structure because of which the healthcare market in Rostov region is dominated by public health organizations which do not actually compete in the market and therefore are not interested in the marketing activity. Another problem in this field is one channel financing of healthcare organizations of Rostov region which determines the only source of financial resources and it is the system of compulsory health insurance. Another problem is limited business opportunities of healthcare organizations in Rostov region which do not have sufficient opportunities to optimize and diversify their activities according to the principles of marketing. For an integrated solution of these problems, the author presents a promising model for encouraging marketing activities of healthcare organizations in Rostov Region.
Methodical Aspects of Creating a Balanced Staffing Mechanism in the Agrarian and Industrial Complex of the Republic of Crimea
Authors: Anisimova Natalia
Published: October 2019

The article presents the author’s approach to the role, importance and opportunities of applying the balance method and the technique of cross-industry balances in the process of labor market formation in agrarian regions.
Today the balance method is one of the elements of methodical tools in statistical institutions as well as in departmental analytical structures. However, in most cases it is not adapted to market economy requirements, which results in leveling both its methodological advantages and possibilities of practical implementation. In this regard, the aim of the conducted research was the evaluation of opportunities to use the methods of forming cross-industry balances to facilitate the development of staffing mechanism in the agrarian and industrial complex at the regional level. On the basis of the conducted monitoring of the territorial and branch specialization of the Republic of Crimea the author calculates the forecasted indicators of balanced staffing of the agrarian and industrial complex of the region taking into account quantitative and qualitative needs of agrarian enterprises for human resources together with the opportunities of higher and professional education system in agriculture. The paper reveals the imbalance in quantitative and qualitative characteristics of agrarian and industrial complex staffing. The author develops and approves the methodical approach to the assessment of the balanced mechanism of forming human resources capacity in the agrarian sector of the Republic of Crimea. The practical approbation of the suggested method allowed to determine the following forecasted levels of staffing needs in the agrarian and industrial complex of the Republic of Crimea: agriculture in general – 27,6 thousand people, crop production – 17,3 thousand people, livestock production – 6,4 thousand people, food industry – 18,2 thousand people. The perspective direction of further studies is the development of recommendations for providing the conditions for implementing state management mechanisms of the regional system of staff training in the agrarian sector of economy of the Republic of Crimea.

Authors: Buyanova Marina , Averina Irina , Kulakova Alina
Published: October 2019

Modern globalization processes cause the emergence of new threats to society, and necessitate the development of innovative mechanisms to overcome them in order to improve the level of security at various levels of management. The objective of this study is to test the methodology for assessing the level of security of the economic system of the region (based on the use of an integral indicator), as well as the definition of mechanisms for its provision at the meso-level. The structure of this indicator includes aspects of the impact on the stability of the system of the following factors (market, non-market and social ones), based on the system of indicators (the number of employed population, the cost of technological innovation per capita, investment in fixed capital, etc.). The calculation of summary indicators is given on the example of one of the subjects of the Russian Federation (Volgograd region), which allowed to determine negative changes in the level of economic security in the region (significant technological backwardness, consistent depletion of natural resources, growth of budget commitments, etc.). Due to the comprehensive assessment, a list of factors that cause this condition has been identified with the aim of further targeted impact from public authorities to overcome the negative trends in the economic system of the region and (or) leveling their consequences. The development of mechanisms to ensure the economic security of the region, based on the above-mentioned method of integrated assessment, allows not only to fully assess the state of the regional economy, but also to identify the potential to strengthen the position of the entity of the country both at the national and international arena.
New Jersey’s Leave of Absence
Authors: Morris Wesley
Published: October 2019

This past June, Governor Phil Murphy helped take a great stride in making sure that every day counts for the students within New Jersey’s Public Schools when he signed a new bill into law. This new policy will work to ensure that schools and districts understand the level to which chronic absenteeism occurs and guarantee that schools disproportionately afflicted have plans to help fight absenteeism. Specifically, the policy identifies schools who have a greater than 10% absentee rate and requires them to establish a plan for improving attendance. It also requires schools to report the percent of students who are absent more than ten percent of the time on their School Report Card. Attendance is one of the most important aspects in ensuring a successful education for students of all ages. The Governor and state legislature, alongside advocacy groups like Advocates for Children of New Jersey (ACNJ), have taken the first steps in fighting one of the largest issues within New Jersey schools. With that being said, it is still extremely important to consider how the state board of education, along with individual districts and schools, will interpret and comply with the law.

Resumo: O objetivo do estudo foi verificar a adequação da utilização de recursos financeiros para a compra de alimentos provenientes da agricultura familiar no âmbito do Programa Nacional de Alimentação Escolar (PNAE) nas capitais de estados brasileiros e no Distrito Federal. Estudo descritivo, com análise de dados secundários obtidos na página eletrônica do Fundo Nacional de Desenvolvimento para a Educação (FNDE) no espaço dedicado às informações sobre agricultura familiar. Foram investigados os valores repassados pelo FNDE e percentual utilizado na compra de alimentos da agricultura familiar para aquisição de alimentação escolar em capitais dos estados brasileiros e no Distrito Federal no período de 2011 a 2017. Os dados foram coletados em maio de 2019. Das 27 cidades avaliadas, cerca de um terço (33,3%) apresentou compra acima do mínimo recomendado (30%). A Região Norte cumpriu o recomendado (39,4%) enquanto a Sudeste apresentou a menor porcentagem de compra (6,4%). De 2011 a 2017, percebeu-se aumento nos valores totais investidos e no número de cidades compradoras de alimentos da agricultura familiar. Dentre as capitais avaliadas, Boa Vista (Roraima) foi a que mais utilizou recursos para a aquisição de alimentos da agricultura familiar (56,6%). Em 2017, as prefeituras de Boa Vista e Aracaju (Sergipe) ofereceram contrapartida financeira adicionada aos recursos fornecidos pelo FNDE para a compra desses alimentos. Concluiu-se que, no período de 2011 a 2017, apenas um terço das capitais avaliadas utilizou adequadamente a porcentagem de recursos financeiros para a compra de alimentos da agricultura familiar, embora tenha sido percebido aumento gradual na compra desses alimentos, especialmente nas capitais do Norte e Nordeste do Brasil.

Published: October 2019

Resumo: O objetivo deste estudo foi estimar a associação entre perda auditiva e mobilidade urbana ativa (a pé e/ou de bicicleta), segundo a percepção sobre o ambiente em adultos de três capitais brasileiras. Trata-se de um estudo transversal com 2.350 adultos (18-59 anos) residentes das cidades de Brasília (Distrito Federal), Florianópolis (Santa Catarina) e Porto Alegre (Rio Grande do Sul), avaliados pelo estudo multicêntrico Mobilidade Urbana Saudável (MUS), em 2017 e 2018. A variável de desfecho foi a mobilidade urbana ativa (≥ 10 minutos/semana), e a exposição principal foi a perda auditiva autorreferida. As análises foram estratificadas pela variável percepção do ambiente - percepção dos lugares para caminhar e andar de bicicleta (negativa; positiva). Utilizou-se a análise de regressão logística, estimando-se as odds ratio (OR) brutas e ajustadas, com intervalos de 95% de confiança (IC95%). A prevalência de perda auditiva autorreferida e de mobilidade urbana ativa foi de 17% (IC95%: 15,4; 18,4) e 55,4% (IC95%: 53,4; 57,4), respectivamente. Adultos com perda auditiva e que percebiam o ambiente de forma negativa para caminhar e andar de bicicleta possuíam 34% menos chance de realizar mobilidade urbana ativa ≥ 10 minutos/semana (OR = 0,66; IC95%: 0,45; 0,97). Conclui-se que houve associação entre perda auditiva e mobilidade urbana ativa dos adultos das três capitais brasileiras, segundo a percepção negativa sobre o ambiente. Pessoas com perda auditiva que percebem negativamente o bairro tendem a se deslocar menos por meios de transportes ativos.

Resumo: Estudos sobre práticas alimentares no contexto do Programa Nacional de Alimentação Escolar (PNAE) têm apontado um paradoxo: de um lado, o PNAE avançou como política fundamentada no direito humano à alimentação adequada e, de outro, ainda apresenta um viés assistencialista que tende a contribuir para identidades estigmatizadas. Considerando esse contexto, um estudo foi realizado, objetivando compreender as interações entre práticas alimentares em torno da alimentação escolar e identidades. A abordagem etnográfica se configurou como percurso teórico-metodológico, tomando, como cenário, uma escola pública no Município de Santo Antônio de Jesus, Bahia, Brasil, do segundo ciclo do Ensino Fundamental. A etnografia foi realizada durante sete meses, sendo constituída de observação do cotidiano alimentar da escola, com registros em diário de campo, assim como realização de 23 entrevistas com alunos e atores-chave. A análise do material produzido consistiu em um exercício hermenêutico e categorização dos temas que emergiram. Este artigo é um recorte dessa investigação em que duas categorias são apresentadas: a primeira, “A escola é nossa”, analisa um movimento de ressignificação da escola ante uma identidade estigmatizada; a segunda, “A comida é o que une”, apresenta a alimentação escolar como um elemento estruturante das identidades dos alunos e da própria escola. Os achados apontam também o quanto o diálogo entre o campo da educação e o campo da alimentação e nutrição pode contribuir para que a alimentação escolar integre as práticas escolares não como um mero suporte nutricional, mas como comida que valoriza a escola pública e seus sujeitos.
Sustentabilidade e CTS: o necessário dialógo na/para a Educação em Ciência em tempos de crise ambiental
Authors: Freitas Nadia Magalhães da Silva , Marques Carlos Alberto
Published: October 2019

RESUMO O presente trabalho traz resultados complementares de uma pesquisa anterior, que buscou responder: em que termos se observa a inserção do tema (in)sustentabilidade em trabalhos de teses e de dissertações que se caracterizaram como análise de práticas/ações de Educação em Ciências/Educação Científica e Tecnológica, com enfoque CTS, na abordagem de temas socioambientais. A abordagem sobre sustentabilidade carrega em si a valorização da dimensão ambiental, constituindo-se o core das discussões, especialmente no âmbito educacional, principalmente no contexto das relações CTS. Isso pressupõe ponderar sobre os impactos, por vezes irreversíveis, da exploração da natureza, principalmente sob a égide do capitalismo, o que inexoravelmente envolve o problema da insustentabilidade. Todavia, não se pode restringir a análise em apenas uma das dimensões dos processos insustentáveis, sob o risco de adotarmos uma concepção reducionista e fragmentada, apartada de uma abordagem multidimensional da questão. Em função da vigência de uma crise ambiental, o problema da insustentabilidade assume múltiplas dimensões, com inserção no campo social, econômico, ambiental, ético, entre outros, e sua abordagem tem referência forte nas relações CTS, mas apresenta-se subteorizada principalmente na sua vertente social. Assim, uma abordagem multidimensional das relações CTS na educação em ciências possibilita considerar a (in)sustentabilidade em sua multirreferencialidade de fatores. Ao revelar as convergências destes dois campos “Sustentabilidade e CTS”, no campo educacional, estaremos ampliando tanto a visão crítica das relações CTS quanto favorecendo a sensibilidade socioambiental.
As velhas novas perspectivas educativas frente à crise ética
Authors: Neitzel Odair
Published: October 2019

RESUMO O presente artigo é de revisão bibliográfica, de cunho analítico e hermenêutico, com o qual pretendemos realizar uma discussão sobre educação, orientada filosoficamente. Nossa problematização se constrói a partir da constatação de que a sociedade contemporânea, apesar da sofisticação, dos avanços na comunicação e interação, do acesso à informação e ao conhecimento, não deu conta de superar velhas mazelas e problemas humanos. E, por essa razão, muitos problemas novos exigem velhos argumentos, reflexões e conceitos, pois, mesmo se apresentando como novos, são velhas as soluções. Para nossa argumentação, consideramos que esse processo se intensificou naquilo que Giddens conceituou como mecanismos de desencaixe e figuras simbólicas, nos levando a considerar, em tese, que a ficha simbólica mais radical, não abordada por Giddens, é a das redes de comunicação e da relação virtual. Esse processo levou a um agravamento da insegurança ontológica do eu e, por consequência, a uma certa crise ética. Essa perspectiva desafia a educação e a formação humana a se repensar diante da fragilização da autoidentidade. Para tanto, servimo-nos de Foucault e Herbart para defender uma educação como cuidado de si, com vistas ao fortalecimento do caráter moral e a uma existência ética frente à relativização moral.
New study practices. Survey on the use of new and old technologies among university students
Authors: Marchionne Ilaria , Bartolini Rudi , Dantas Taisa Rodrigues
Published: October 2019

ABSTRACT In a context of “widespread communication”, supported by new tools and work environments, study practices also change, profoundly transforming students’ habits and behaviors. The research in question intends to investigate and describe, through a narrative inquiry process, the study practices of university students, making reference to the integrated use they make of old and new modes of communication, of traditional texts and of digital platforms and tools among the most famous and widespread. The research focuses in particular on the relationship that, through the new tools, is established between the student and the teacher, between the student and colleagues and between the student and the study texts. The analysis aimed at describing new habits, will try to demarcate advantages and difficulties related to the use of digital and to analyze, specifically, how the use of new communication methods or new forms of textuality can favor or inhibit communication within the university environment.
De como ensinar: traços paradigmáticos nos manuais pedagógicos e perspectivas de investigação (1870-2015)
Authors: Garcia Tânia Maria F. Braga , Silva Vivian Batista da
Published: October 2019

RESUMO O objetivo do artigo é contribuir para a produção de conhecimento sobre manuais destinados à formação de professores, focalizando particularmente as obras usadas no ensino de disciplinas como a Pedagogia, a Didática, a Metodologia e a Prática de Ensino, em perspectiva ainda pouco explorada na pesquisa educacional. Denominados de manuais pedagógicos, têm sido publicados no Brasil desde 1870 com a intenção de garantir aos futuros professores uma formação especializada. A complexificação da Didática como campo de conhecimento e o fortalecimento das Didáticas Específicas produziram transformações nesse conjunto de obras ao longo dos últimos quarenta anos, demandando revisões conceituais e novas perspectivas de investigação, apontadas pelas autoras nesta síntese realizada a partir dos resultados de suas pesquisas.
Pistas para uma Cartografia Performativa da ‘Nova Direita’ (2015-2019)
Authors: Melo Thálita Motta
Published: October 2019

Resumo: O trabalho busca tecer uma reflexão a partir do revés da performatividade, ao cartografar a estetização da política e a politização da arte, produzida a partir da ascensão da nova direita no Brasil recente, permeando aspectos de sua performatividade. Em conclusão, são discutidas questões adjacentes à carnavalização, a partir das estratégias da alegria, analisadas em Belo Horizonte e seu carnaval de rua, como vislumbre estético-político em meio ao barril de cópias mal forjadas da nova direita, caracterizada pela estratégia da guerra híbrida, marco da falsificação da história, como táticas para a disputa de território geopolítico.
Quando Camponeses Entram em Cena: trabalho teatral do MST e a interface com a linguagem audiovisual
Authors: Villas Bôas Rafael Litvin , Canova Felipe
Published: October 2019

Resumo: Neste artigo é analisada a presença dos camponeses no teatro brasileiro, em perspectiva histórica desde os anos pré-golpe de 1964 até o período recente, no qual as conexões foram estabelecidas entre movimentos sociais como o MST e coletivos de teatro político e vídeo popular. São objeto de análise do trabalho as relações do MST com esses coletivos e os lugares que a linguagem teatral passou a ocupar no MST, bem como as influências de diversas formas teatrais e a relação dessa linguagem com o audiovisual. A pesquisa procura destacar que a relação mediada pela socialização dos meios de produção artísticos é capaz de recolocar os termos do debate entre tema e forma: se a terra pode ser de todos, a arte também é um elemento inerente à condição humana, e não apenas relegado aos que se especializaram no ofício.
O mundo nas mãos do adolescente: entre Apolo e Dioniso, entre o eros e o caos
Authors: Mastroberti Paula
Published: October 2019

Resumo A partir da série Poderosa, de Sérgio Klein, analiso a representação do adolescente na personagem-heroína Joana Dalva, que tem o dom de mudar os acontecimentos através da escrita. A análise parte da polaridade Apolo/Dioniso conforme Friedrich Nietzche e começa por apresentar a série em seu contexto gráfico, mostrando como ele contribui para a identificação entre texto e destinatário; a seguir, apresento a protagonista em suas relações com os demais elementos narrativos, refletindo sobre o modo como ela exerce seu poder e seu significado enquanto metáfora dos conflitos psíquicos e corpossensuais causados pelas transformações próprias da idade. O trabalho inclui um breve panorama historiográfico da juventude a partir das relações do seu corpo com o corpo coletivo, ou sociocultural, auxiliando a localizar a obra de Klein na pós-modernidade e confirmando-o como sintoma de uma visão apolinizada do adolescente pela sociedade contemporânea. Para concluir, junto com o relato das informações obtidas a partir de uma rápida enquete feita com bibliotecárias de Porto Alegre e de outras cidades do Rio Grande do Sul, situo a série no sistema literário e procuro diagnosticar as causas do seu êxito junto ao jovem público leitor.

Authors: Luft Gabriela
Published: October 2019

Resumo O artigo apresenta um estudo sobre a literatura juvenil brasileira publicada na primeira década do século XXI, por meio da análise de obras premiadas pela Fundação Nacional do Livro Infantil e Juvenil e pela Câmara Brasileira do Livro, que outorga o prêmio Jabuti. A partir de dados sistematizados por Marisa Lajolo e Regina Zilberman, apresenta-se um breve panorama da literatura infantojuvenil brasileira entre o período de 1890 a 1980, contextualização que permite o delineamento do percurso e das tendências do gênero ao longo do tempo. Após, com base nos estudos desenvolvidos por Teresa Colomer, expõem-se os principais traços da literatura juvenil atual, os quais são cotejados com as características das narrativas juvenis brasileiras premiadas entre os anos de 2001 e 2009. Por meio da leitura, da observação, da análise e da comparação das obras que integram o corpus, procura-se demonstrar as características da literatura juvenil brasileira produzida na primeira década do século XXI, de maneira a responder quais as principais tendências do gênero e qual sua posição no cenário nacional. Verificase o surgimento de um bom número de autores novos, a diversidade de temáticas trabalhadas e o aumento da complexidade narrativa.

Published: October 2019

RESUMO Objetivo Obter informações sobre saúde e higiene vocal, sintomas vocais e desvantagem vocal de estudantes de teatro com e sem queixa de voz. Método Participaram da pesquisa 57 alunos de teatro que foram divididos em dois grupos: grupo sem queixa vocal (GSQ), composto por 39 alunos; grupo com queixa vocal (GCQ), composto por 18 alunos. Os participantes responderam a três protocolos de autoavaliação: 1. Questionário de Saúde e Higiene Vocal (QSHV); 2. Escala de Sintomas Vocais (ESV); 3. Índice de Desvantagem Vocal (IDV-10). Resultados Não houve diferença entre os grupos quanto aos conhecimentos de saúde e higiene vocal. Os estudantes de teatro do GCQ apresentaram maiores escores, mais sintomas vocais em todos os domínios do instrumento ESV e mais desvantagem vocal percebida no IDV-10 que os do GSQ. Quanto maior foi o conhecimento em saúde e higiene vocal (domínio total do QSHV), menores foram os sintomas vocais nos domínios emocional e total (ESV), e a desvantagem vocal foi percebida (domínio total do IDV-10) apenas no GCQ. Conclusão Não houve diferença quanto ao conhecimento sobre saúde e higiene vocal entre alunos de teatro com e sem queixa vocal. Contudo, os alunos de teatro com queixa vocal apresentaram mais sintomas vocais e referiram percepção de mais desvantagem vocal, aspectos esses que se correlacionaram negativamente com o conhecimento sobre saúde e higiene vocais.
