O núcleo docente estruturante enquanto espaço de gestão pedagógica: Possibilidades e desafios / The structuring teaching nucleus as a pedagogical management space: possibilities and challenges
Authors: Scorzoni Marília Ferranti Marques , Schiabel Daniela , Rivas Noeli Prestes Padilha
Published: February 2022

O Núcleo Docente Estruturante (NDE) é um conceito criado pela Portaria nº 147 de 2 de fevereiro de 2007 que, posteriormente, é normatizado pela Resolução nº 1 de 17 de junho de 2010. Tal resolução determina que o NDE de um curso de graduação deve ser composto por, no mínimo, 5 docentes que tem como principal atribuição a concepção e acompanhamento do projeto pedagógico do curso. Constitui-se, assim, enquanto importante espaço de gestão pedagógica que analisa e articula a dimensão institucional, legal e pedagógica na concepção dos cursos de graduação e, nesse sentido, reflete em suas atribuições as tensões das normativas legais e do contexto institucional em que está inserido. Nesse contexto, o objetivo do presente estudo é analisar e identificar a partir dos documentos legais (Portarias, Pareceres e Resoluções) e dos estudos acerca do NDE (CAMPOS FILHO, 2014; DUDEQUE, FILIPAK, 2015; SAKR, DUDEQUE, 2019; NUNES, 2018; MATIAS, 2020) a contribuição e os desafios do NDE no que se refere a gestão pedagógica. As normativas e os estudos analisados apontam a relevância do NDE para a concepção do curso e organização de atividades acadêmicas, mas também, evidenciam a pouca autonomia dos membros do NDE na execução de propostas pedagógicas. Outro aspecto identificado foi a relação do NDE com as políticas de avalição que imprimem nas atividades desempenhadas um caráter instrumental e, muitas, vezes, meramente burocrático.

Published: February 2022

Os Cadernos de Apoio à Aprendizagem são recursos didáticos formados por trilhas de aprendizagem com a finalidade de conciliar os tempos e os espaços do ensino remoto emergencial e assim auxiliar professores e estudantes durante esse período. Nesse sentido, foi importante elencar conteúdos significativos, como a biotecnologia, sempre presente nos Exame Nacional do Ensino Médio (ENEM). O objetivo desse estudo foi analisar o tema biotecnologia no Caderno de Apoio à Aprendizagem à luz da transposição didática e foi realizado por bolsistas de iniciação à docência do curso de Licenciatura em Ciências Biológicas da Universidade do Estado da Bahia (UNEB), campus II, Alagoinhas-BA. Com abordagem qualitativa foi realizada uma análise comparativa da biotecnologia tendo como parâmetro o livro Biotecnologia, quanto a efetiva transposição didática, destacando-se os processos de transformação que o conhecimento científico sofre quando passa para o recurso didático. As questões que nortearam a análise foram: o que é biotecnologia? quais as contribuições da biotecnologia para a sociedade? os cadernos de apoio apresentam sugestões de leituras? A biotecnologia é uma área multidisciplinar que utiliza agentes biológicos cujas aplicações contribuem para resolução de problemas e produtos úteis, diferente do caderno de apoio, que conceituou de forma superficial e, suas contribuições estão resumidas em listas, exceto o processo de fermentação, além de apresentar sugestões de leitura através de links por vezes inacessíveis. Dessa forma, revela-se a importância do saber docente ao transpor esses conteúdos de forma bem explicada e objetiva para os discentes.

Technologies for extraction and fractionation of phenolic compounds from a typical propolis from northeastern Brazil, called red propolis, using supercritical fluids may represent an environmentally correct alternative to the current extraction processes, as they are included in the concept of "green chemistry". The objective of this work was to extract and fractionate the phenolic compounds from red propolis: I) Using supercritical carbon dioxide (scCO2) as solvent and ethanol as co-solvent to obtain an ethanolic extract; II) Using scCO2 as solvent and a mixture of ethanol: water (70:30, v / v) as co-solvent to obtain a hydroalcoholic extract. After extraction, the ethanolic and hydroalcoholic extracts were fractionated using scCO2 as antisolvent at a constant temperature of 50 ºC, subjected to four gradual pressures, in a sequential of separators operated at 200, 100 and 80 bar, at the end, atmospheric pressure (1.013 bar). The procedure was characterized according to extraction yield; total phenols, total flavonoids, antioxidant activity and color. It was found that the pressure influenced the yield and the concentration of the phenolic compounds in the extracts, demonstrating that the most efficient fractionation process occurred in the first and second separators. Overall, all extracts showed high antioxidant activity.

A Síndrome de Asperger (SA) é considerada um transtorno ocasionado por uma desordem neurobiológica de origem ainda desconhecida, sendo um subtipo brando do Transtorno do Espectro Autista. O paciente portador de SA possui características específicas que são determinantes para o diagnóstico, este, geralmente ocorre na primeira infância, e, realizado de forma precoce, auxilia o tratamento que deve perdurar durante toda a vida, haja vista que a síndrome não tem cura. No que concerne ao tratamento, percebe-se benefícios na atuação multiprofissional que almeja fomentar o desenvolvimento social, a comunicação verbal e não verbal, o estabelecimento de autonomia e educação do paciente, e sua capacidade física e emocional. Assim, essa condição foi analisada neste trabalho através de uma Revisão Integrativa da Literatura (RIL) baseada em uma pesquisa nas bases de dados das plataformas virtuais Biblioteca Virtual em Saúde (BVS), Medical Literature Analysis and Retrieval System Online (MEDLINE) via Pubmed e Google Acadêmico. Em seguida à leitura completa dos artigos selecionados, após aplicação dos critérios de inclusão e exclusão, concluiu-se que a SA afeta significativamente a qualidade de vida do portador e de seus familiares. Por isso, constatou-se que a mesma deve ser diagnosticada precocemente e que o tratamento de forma correta auxilia em um prognóstico positivo a longo prazo para o desenvolvimento do indivíduo portador.

Se realizaron pruebas de aceptabilidad de la Harina de Aguacate (HA) en ovinos y cerdos. Tres animales de cada especie fueron empleados en cada prueba durante siete días de experimentación para valorar la aceptabilidad mediante la prueba de cafetería ofreciendo a cada animal dietas con diferentes niveles de inclusión. La dieta en ovinos con nivel de inclusión del 10% fue la mejor aceptada, así como una relación de F-C del 40-60%. Se observa una depresión al aumentar la inclusión de la HA en -0.015 a -0.029 kg del consumo por cada 1% de HA en la dieta. En Cerdos el consumo aumento cuando la inclusión fue menor al 10%, éste nivel fue el de mayor consumo comparado con los de más alta inclusión. Tiende a preferirse los niveles más bajos al disminuir el consumo -0.034 a -0.063 kg por cada 1% de HPA en la dieta. Se pueden diseñar dietas que incluyan la HA en un 10% en ovinos y cerdos, disminuyendo la cantidad de forraje en ovinos.

The Collective West Concept and Selected Western Actors (Germany, Norway, Estonia, NATO) in the Russian Media: Post-Crimea Dynamics
Authors: Chimiris Ekaterina
Published: February 2022

The Post-Crimean period gave us a series of new concepts in international relations, and one of them is the Collective West Concept. Being invented in the academic sphere several years before the Crimean case, the concept intervened the Russian public and political discourse. In this article I argue that the Collective West concept has become an instrument of additional securitization of the West in the discourse of Russian media. To prove the hypothesis, I have used the discourse analysis and concept mining methodology. I have created a sample of Media messages and by means of concept mining soft have coded the sample. In this research project I was interested in finding correlations between the Collective West and separate Western countries and actors (NATO, Germany, Norway, Estonia). After creating a correlation model for these concepts, I have looked at the overall semantic and argumentation context of the concepts usage. The results of the research give me an opportunity to conclude, that the Collective West Concept is mostly used by Russian Media in negative context. Such big international actors as Germany is included in the Collective West Concept, when the context of speaking about it is also negative.

This study deeply analyses the Japanese series Dragon Ball, broadcast by ETB1 in the 90s, and it is focused on the use of the different address forms in the Basque translation. We describe the qualitative work about the contents of the series and the information elicited during the interviews to the main agents of the translation process. The translators took much advantage of the informal form of address, not only because many characters use it very often, but also because the different connotations that hika can suggest are present in the series. We specially observed a top-down use of hika, and this hierarchy is established by different factors: age, power and evil, among others. 90eko hamarkadan ETB1ek igorritako Dragoi Bola telesail japoniarraren azterketa xehea egiten da lan honetan, euskarazko itzulpenean hizkuntza-tratamenduei ematen zaien erabilerari erreparatuta.

Published: February 2022

La invaginación intestinal ha dado origen a una gran cantidad de publicaciones. Es Leichtenstern quien en el afio 1873 expone la gran riqueza de casos publicados en la literatura médica mundial. En su conocida monografía cita 593 casos, dando una lista completa de todas las publicaciones aparecidas. Posteriormente se renueva la bibliografía de las invaginaciones, pero sin lugar a duda es necesario nombrar la celebre monografía de F. Treves (Intestinal Obstruction) en el afio 1884, punto de partida de los posteriores trabajos en las diversas citas. A través de su trabajo deja ver el autor su genio clínico de observador sagaz, al decir que los pólipos eran la causa más frecuente en el origen do la invaginaoión. En lo que se refiere al tratamiento, indicaba con claro ejemplo que la precocidad en la íntervención regía el pronóstico.
Fabrication of nanostructured Pt electrodes templated by nanoporous anodic alumina for electrochemical sensors
Authors: Turkevych Ivan , Fukuda Nobuko
Published: February 2022

Although platinum electrodes are widely used in electrochemical sensors their functionality can be affected by formed components of complex biological fluids. We demonstrated a simple approach to the formation of Pt nanopillars sandwiched between W metal layers and nanoporous anodic alumina membranes, by anodization of W/Al bilayers and substitution of WO3 nanopillars formed by the local anodization of W under the nanopores with Pt. By exploiting the Pourbaix corrosion diagram of W, we could find conditions that allow the selective dissolution of WO3 in pH = 7.4 buffer solution and formation of Pt nanopillars inside the nanoporous aluminum membrane via electroless deposition.

This paper is succession planning and family–owned business:an assessment of impact on selected family-owned businesses. Furthermore, the study assesses the relationship between mentoring and sustainability of selected family-owned business in Ibadan. It also evaluates the differences between roles modeling on survival of family-owned business in Ibadan, and finally to find out the differences between training and development on growth of family-owned business in Ibadan. The study employed survey research design. The population for this study consists of all staff of selected family-owned business in Ibadan. The total number of 140family business owners/founders was calculated using Taro Yamane’s formula, thus a target population of 215family business owners/founders. The findings of the research showed that mentoring leads to increase in sustainability of selected family-owned business in Ibadan (β = 0.140 P = ≤0.05). Also, the value of coefficient (β = 0.868 P = ≤0.05) is significant and positive, showing that direct and indirect family leads to survival of family-owned business in Ibadan, Oyo State, Nigeria. Finally Training and development were significantly and positively related to growth of family-owned business [r (140) = .636**, p<0.01]. Thus, it was found out that training and development has a positive and statistically significant influence on growth of family-owned business. The study concluded that family-owned wealth management and financial planning businesses have a compelling need for a succession plan. It was recommended that Managers and leaders might use the findings of this study to recognize the importance of succession planning and document future succession plans in a more organized approach and by developing a road map to clarify positions.

This study interrogated the relationships that exist between self-care practices, occupational stress and employees’ burnout amongst security personnel, using Lagos State University, as a reference point. The study utilised the cross-sectional approach of the survey research design, and the convenience sampling technique was adopted to select 118 security personnel for final analyses. Founded on extant literatures, three research hypotheses were stated and tested using the Person’s Product Moment Correlation Coefficient (PPMC), and the Multiple Regression. Whilst one research question was raised and explained using the line graph. The results of the tested hypotheses revealed a significant relationship between self-care practices and burnout. Also, a significant relationship was established between occupational stress and burnout of selected security personnel. While a significant influence of both self-care practices and occupational stress on employees’ burnout was established with an adjusted R2 of 0.18, which presupposes that 18% of the variance in security’s burnout was as a result of self-care practices and employee stress. Also, it was established through a FSB (fasting blood sugar) test that, there exist variations in the sugar level of security personnel. Consequently, this study concludes that security personnel should ensure they draw up workplace stressors, and acquaint themselves with relevant coping strategies to lessening the stressors. Also, the University Management through its security unit should create an enabling working environment, suitable and flexible work-duty schedules, an employees’ wellness programme, and an appropriate stress reduction awareness.
WOMEN ISSUES IN PANDEMIC TIMES: SOCIO ECONOMC EFECTS OF COVID – 19 ON GENDER PARITY

The effects of pandemics are always gender biased therefore, the recovery efforts cannot be gender neutral. Although families are subjected to consummate tests, women are enduring the weight of the economic and social penalties of COVID-19.Gender inequality precipitates gender inequality, and the practice is simply aggravated in periods of crisis or principal blows like the COVID-19 pandemic. To appreciate the effects of the pandemic and to plan policy reactions to the present pandemic, it is significant to take note of prevailing gender disparities and their tendencies to mediate gender influences and roles. Also, to articulate policies that consider established circumstances to deliver a tailored methodology. Governments must pro-actively reach out to women for assistance with tackling the pandemic because of women´s larger engrossment with care of children and the elderly, plus their home-based activities and the actuality that the home is characteristically their purview. Women´s empowerment during this time is consequently more treasured because of their prospective inputs to the response endeavours. The need arises to communicate responses that will consider gender inequalities. The disparities in gender consequences of the pandemic are intensified in specific settings and among particularly susceptible groups.

This study focused on a critical evaluation of collective bargaining policy in Nigeria from the historical perspective. The main objective of this study was to evaluate the structure and system of collective bargaining in Nigeria since the colonial period. The study adopted a conceptual analysis and theoretical explanation of the origin, development, weakness, and state involvement in collective bargaining policy in Nigeria through a critical review of extant literatures. The study revealed that collective bargaining as machinery for wage determination in the public sector is supposed to prevent the unilateral imposition of wages on the union by the government and vice versa as the case may be. However, it is not often used by the Nigerian government to determine wages rather government relied more on wage commissions, wage tribunals, and civil services administrative rules to determine wages in the public sector. Therefore, collective bargaining appears to be ineffective as a potent tool for wage determination in Nigeria’s public sector. The study also discovered that collective bargaining machinery in Nigeria is weak because of government’s direct involvement in collectivebargaining process to review, amend, even absolutely reject the collective agreement reached between unions and the government representative at the bargaining table. The study, therefore, concluded that collective bargaining is not an effective institution within the context of employment relations in Nigeria.

The inevitability of workforce diversity and the legal requirement of employment opportunities and affirmative action have driven the adoption of diversity policies and initiatives by management of many organisations. The objective of this study is to examine the influence of workforce diversity on organisational performance and the moderating effects of human resource management practices (HRMPs) as moderating factor in the relationship between workforce diversity and organisational performance. Descriptive survey design was employed and a sample of 464 respondents were drawn, using Yemane (1967) method, from among 3,280 total employees of four selected Multinational Companies (MNCs) in the Foods and Beverage sub sector of manufacturing companies operating in Lagos State Nigeria. Data were generated through structured questionnaire schedule from the management, senior, middle and junior staff cadres of the selected MNCs. The data collected were analysed using both simple and multiple hierarchical regression statistical analysis. Result obtained of hypothesis One indicated that workforce diversity dimensions (WFDDs) insignificantly influenced organisational performance (OP) with coefficient of determination at R2 = 0.0003. When the components of HRMPs were added to the regression model, there was a significant increase in OP 19.2% (Δ R2 =0.192, p = 0.000) since R2 increased from 0.003 to 0.195. This result shows that HRMPs have enhancing effect on the relationship between WFDDs and OP. the study concluded that Organisations may not likely reap the benefits of increasing WFDDs except they effectively manage their internal process, specifically their HRMPs. It was therefore recommended among other things that approach to research of WFD should be holistic investigation of the contextual factors of organisation for their climate which could be discriminatory or non-discriminatory and the corresponding OP which could be negative or positive accordingly.
