Authors: PANDA SANTANU 
Published: April 2020

Abstract: The chief objective of this paper is to find out the features of Evil, Corruption, Manipulation and Abuse of power in Shakespeare’s Macbeth. Shakespeare is the leading and prominent dramatist of Elizabethan era. He is often regarded as England’s ‘national poet’ and the ‘Bard of Avon’. The full title of Macbeth is ‘the Tragedy of Macbeth’. This is a tragedy where hellhound becomes a hero. Shakespeare presents the psychological battle in Macbeth through soliloquy and aside. As a result Macbeth’s physical action are distinct from his mental actions. The source of Macbeth is Holinshed’s Chronicles. Shakespeare modified many facts of stories from the purpose of tragic effect. The play opens with the witches. The witches belong to natural calamity symbolically they are associated with the calamity in human nature. The witches implicitly mention two battles. They know that Macbeth will open the physical battle. But they also know that they will defeat Macbeth in physical battle. The witches are single in their purpose. They want to meet Macbeth to united strength of the evil sets as a contrast to the rebellion against Duncan. Macbeth killed Duncan to acquire the crown. To collect it he uses the tricks of corruption and Manipulation. He also misuses the power to maintain his kingdom. He killed Banquo and Macduff’s innocent wife and child. But he forgot that the crown for which he and his wife killed Duncan and several on and bring a tempest on their life it will be the cause of their destruction.

Modelagem Matemática: um olhar semiótico
Authors: Veronez Michele Regiane Dias , Chulek Carina 
Published: April 2020

O desenvolvimento de uma atividade de modelagem matemática a partir dos interpretantes produzidos por alunos de um primeiro ano do Ensino Médio é focalizado nesse texto à luz da teoria semiótica peirceana. A metodologia que subsidia o estudo realizado é de cunho qualitativo, já que temos por interesse discutir acerca dos signos produzidos pelos alunos ao longo do desenvolvimento de uma atividade de modelagem matemática. Como resultados, ponderamos que o processo de geração de (signos) interpretantes depõe (des)conhecimentos dos alunos, seja sobre Matemática, seja sobre a situação e/ou problema que desencadeou a atividade de modelagem matemática em foco. Além disso, esse processo favorece uma dinamicidade na geração dos interpretantes, proporcionada devido ao uso do software GeoGebra e leva os alunos a assumirem atitudes autônomas ao longo do desenvolvimento da atividade de modelagem matemática.

Authors: Barbalho Alexandre 
Published: April 2020

O artigo analisa a reação do sistema político tradicional, mais especificamente da elite parlamentar brasileira, diante da proposição de criação do Banco do Nordeste do Brasil em 1959. Parte-se do pressuposto de que a futura instituição seria uma agência insulada de demandas clientelistas e corporativistas o que poderia minar as bases eleitorais sustentadas em relações personalistas. A partir do método posicional e da análise de documentos, investigou-se as tomadas de posição dos congressistas durante a tramitação no Congresso da referida proposta, tanto em suas falas no plenário da Câmara, quanto em seus depoimentos à imprensa. Como conclusão, a análise revelou que houve um consenso nacional em torno da nova instituição, para além de clivagens partidárias e regionais.

Design: This observational cross-sectional study used a quantitative survey to obtain information about Illinois pharmacists’ knowledge, concerns and educational needs about OTC-CBD products. Survey questions were based on prior research and pilot tested for clarity and completeness. Descriptive statistics were utilized to assess all data.
Setting and Participants: The study researchers collaborated with two state-based pharmacy organizations to distribute the survey online with up to two reminders.
Results: A total of 181 participants completed the survey. Majority of the respondents were 31-60 years of age, had worked in pharmacy for less than 5 years, in a geographic location with a population of 50,000 or more. About 41% worked in hospital-based practice setting and 39.2% work in a community-based setting. Most pharmacists (64.1%) reported ever being asked about the safety or efficacy of cannabidiol containing products, and only 20.7% responded that they felt moderately/highly prepared to provide medication counseling to patients who use OTC-CBD products. Majority of respondents reported being concerned about safety, quality, and regulations related to OTC-CBD products. Almost all respondents indicated that information about state (90.5%) and federal (89.4%) laws related to CBD, and safety (99.5%) were preferred topics for future education.
Conclusions: Consumers are seeking information about CBD containing products; however, many pharmacists do not feel prepared when it comes to being the drug expert for these products. Educational opportunities are necessary for pharmacists to become more comfortable and knowledgeable regarding safe and effective use of CBD-OTC containing products.
