The instrumentalization of metaphors in the management field: reflections from the use of the book "the art of war" on business

Abstract: The debate about the use of metaphors in the organizational context in the last decades has not been exhausted, especially in discourse studies. Inserting itself in this discussion, the present essay problematizes the anachronistic dimension in the use of metaphors in the field of management. From a hermeneutic-critical perspective, we argue that the use of metaphors in managerial literature sometimes reflects a utilitarian and anachronistic distortion of the contexts originating in metaphorical symbolic forms. In this sense, the strategic use of language can inhibit the interpretive autonomy of individuals, that is, colonize their interpretive horizons by the persuasive induction of simplistic and utilitarian worldviews about organizational reality. We use the essay form as a method, and we rely theoretically on Alvesson’s critical approach, on the hermeneutics by Gadamer and Ricoeur, and on Habermas’ Critical Theory. We illustrate our argument by recurring use of the work “The Art of War” as a metaphor for managerial practice.

Sistema de Avaliação Ambiental para Projetos de Edificações Públicas (SAAPE): análise dos critérios de sustentabilidade de três projetos de edificações elaborados para a Universidade Federal do Paraná

Abstract: A construcao civil e uma atividade que gera impactos ao meio ambiente, muitas vezes negativos. As obras contratadas pelo Governo Federal representam um grande volume e necessitam de um planejamento adequado do ambiente a ser construido, visando causar o menor impacto possivel nos ecossistemas naturais. Algumas iniciativas do governo para estabelecer diretrizes de sustentabilidade foram implantadas, como a Instrucao Normativa 01/2010, porem na pratica esta instrucao ainda e pouco utilizada. A realizacao desta pesquisa justificou-se pela necessidade de melhorar o desempenho ambiental das edificacoes publicas a fim de reduzir o impacto causado no meio ambiente. Com base em tres reconhecidas certificacoes ambientais para edificacoes, por meio de matrizes de comparacao, foram relacionados as suas categorias e os criterios a fim de verificar quais atendem as diretrizes indicadas na IN 01/2010 e quais sao os mais importantes e que devem estar presentes para complementar o modelo proposto. O sistema desenvolvido, denominado SAAPE, e composto por seis categorias de desempenho ambiental, que se desdobram em 44 pontos a serem cumpridos. O sistema foi aplicado em tres projetos da Universidade Federal do Parana, para validar sua aplicabilidade e para verificar a situacao dos projetos elaborados para este orgao. Os resultados obtidos mostram que em nenhuma das edificacoes pesquisadas foi possivel obter a pontuacao minima, que e de 18 pontos, estando entre 14 e 15 pontos. Porem, ainda que de forma embrionaria, algumas solucoes que buscam reducao nos impactos ja estao sendo adotadas. Posto isso em pratica, o sistema elaborado visa auxiliar os gestores publicos, arquitetos e engenheiros para que, durante a preparacao dos projetos de obras publicas, respeitem os criterios de sustentabilidade ambiental dispostos na IN 01/2010, alem de fornecer oportunidades de melhorias da qualidade em relacao aos aspectos de sustentabilidade na fase de concepcao de projetos.

Effect of Local Application of Alendronate and Parathyroid Hormone on Craniofacial Bone Repair - a Preliminary Study

Abstract: This study aimed to evaluate the effect of two methods of local application of alendronate and parathyroid hormone (PTH) on bone repair and the systemic implications. A critically sized defect (5 mm) was created in the cranial region of twenty-five male Wistar rats, and the bone removed was particulated, and grafted back to the defect with different treatments. The animals were randomly divided into five groups: A1- bone graft immersion in alendronate solution (3 mg/kg) for 5 minutes; P1- bone graft immersion in PTH solution (20 µg); A2- weekly local applications of alendronate 1 mg/kg; P2- weekly local applications of PTH (20 µg); C- no drugs were used. The animals were euthanized 60 days after surgery. Cranial bone blocks were removed for histological, histomorphometric, and immunohistochemical analyses. MMP-2 and MMP-9 were used for immunolabeling. The kidneys, liver, and brain were also removed from all the rats for histological analysis. The data were submitted for statistical analysis with a level of significance of 0.05 (One-way ANOVA). The group C and group P2 presented a higher quantity of viable bone particles than the remaining groups. Groups A1, A2, and P1 presented with fewer viable bone particles than the control group, with a predominance of non-mineralized connective tissue. The histomorphometric analysis revealed no differences in relative bone area or MMP-2 or MMP-9 immunolabeling between the groups (p>0.05). Group A2 showed presence of fat in the liver consistent with hepatic steatosis. Changes in brain tissue were observed in groups A1 and P1.

Fake news: the impact of the internet on population health

Abstract: SUMMARY OBJECTIVE: The aim of this study was to evaluate the search for health information on the Internet and to determine the frequency and main means of spreading fake health news. METHODS: A descriptive cross-sectional study was conducted through the virtual distribution of questionnaires on social media platforms in 2019 by using the snowball technique. The questionnaire collected information regarding sociodemographics, means used to clarify doubts about health, implementation of information obtained through the Internet, receipt of fake news, and means of transmission of fake news. Quantitative variables are described as means and standard deviations, and categorical variables are described as frequencies and percentages. The chi-square and Fisher’s exact tests were used. RESULTS: Out of 1,195 respondents, 53% had followed Internet guidance without consulting a health professional, especially young people and individuals with low education levels (p<0.05). The resources most used to answer questions about health were a physician (78%) and Google (51%), and searches using the latter were more predominant among younger age groups (p<0.05). A large part of the sample (89.4%) had received fake news, and the main means of receipt were Facebook and WhatsApp. CONCLUSIONS: The Internet was the second most commonly used means to search for health information. A significant portion of the population adopts actions based on this information. The frequency of broadcasting fake news through this digital medium is high.
