Internacionalização no segmento de mídia out of home: o caso da JCDecaux no mercado brasileiro

Purpose - This case study aims to understand the motivations for the expansion of the French multinational JCDecaux to Brazil, in the light of relevant theories about the internationalization of companies. JCDecaux is the world's largest outdoor media company (out of home), a fast-growing industry of the advertising market in Brazil.Design/methodology - This study explain the case based on the internationalization of companies theories, in the economic (Eclectic Paradigm of International Production) and behavioral (Uppsala School and Business Networks Model) strands. In addition to secondary sources, the research was supported by interviews with experts and executives from the outdoor media industry in Brazil.Findings - The main determining drivers for the entry of JCDecaux in the Brazilian market were identified. The analysis based on the theoretical models of internationalization concluded that the economic approach determined in a more significant way the company's entry into the Brazilian media out of home market. Economic advantages outweighed the costs and risks of Brazil's business environment, making the country attractive to the company's foreign investment.Research limitations - The scarcity of data about the media outdoor was reported by a professional interviewed as a negative feature. Another important limitation is the lack of scientific production about the out-of-home media in Brazil.Originality - This paper contributed to generate important information about the Brazilian outdoor media industry, especially on the phenomenon of internationalization of companies in this industry.Propósito - Este estudo de caso visa compreender as motivações para a expansão da multinacional francesa JCDecaux para o Brasil à luz de teorias relevantes sobre a internacionalização de empresas. A JCDecaux é a maior empresa de mídia outdoor (out of home) do mundo, um segmento em crescimento do mercado publicitário Brasileiro.Design/metodologia - Este estudo explica o caso baseado nas teorias de internacionalização de empresas, nas vertentes econômica (Paradigma Eclético da Produção Internacional) e comportamental (Escola de Uppsala e Modelo de Redes de Negócios). Além de fontes secundárias, a pesquisa contou com entrevistas com especialistas e executivos da indústria de mídia outdoor no Brasil.Resultados - Foram identificados os principais determinantes para a entrada da JCDecaux no mercado brasileiro. A análise baseada nos modelos teóricos de internacionalização concluiu que a abordagem econômica determinou de forma mais significativa a entrada da empresa no mercado brasileiro de média outdoor. As vantagens econômicas superaram os custos e riscos do ambiente de negócios do Brasil, tornando o país atraente para o investimento estrangeiro da empresa.Limitações da Pesquisa - A escassez de dados sobre a mídia outdoor foi relatada por um profissional entrevistado como um fator negativo.

All Rights Reserved.NorA is the best studied efflux system of Staphylococcus aureus and therefore frequently used as a model for investigating efflux-mediated resistance in this pathogen. NorA activity is associated with resistance to fluoroquinolones, several antiseptics and disinfectants and several reports have pointed out the role of efflux systems, including NorA, as a first-line response to antimicrobials in S. aureus. Genetic diversity studies of the gene norA have described three alleles; norAI, norAII and norAIII. However, the epidemiology of these alleles and their impact on NorA activity remains unclear. Additionally, increasing studies do not account for norA variability when establishing relations between resistance phenotypes and norA presence or reported absence, which actually corresponds, as we now demonstrate, to different norA alleles. In the present study we assessed the variability of the norA gene present in the genome of over 1,000 S. aureus isolates, corresponding to 112 S. aureus strains with whole genome sequences publicly available; 917 MRSA strains sourced from a London-based study and nine MRSA isolates collected in a major Hospital in Lisbon, Portugal. Our analyses show that norA is part of the core genome of S. aureus. It also suggests that occurrence of norA variants reflects the population structure of this major pathogen. Overall, this work highlights the ubiquitous nature of norA in S. aureus which must be taken into account when studying the role played by this important determinant on S. aureus resistance to antimicrobials.publishersversionpublishe

Microbiological characterization of protected designation of origin Serra da Estrela cheese

Serra da Estrela is the oldest and most recognizable traditional protected designation of origin (PDO) cheese from Portugal. It has been extensively studied over the years, but the latest microbial characterization is 20 years old. Hence, this work aimed to perform an updated characterization of Serra da Estrela PDO cheeses and raw materials. Our analysis showed that lactic acid bacteria content on Serra da Estrela cheeses exceeded 8.8 log CFUsg−1 , in all analyzed samples, with lactococci, lactobacilli and Leuconostoc spp. predominating over enterococci strains. Moreover, lactococci and lactobacilli abundance increased across the production season, while enterococci dropped considerably in late manufactures. Lastly, Leuconostoc spp. content remained unchanged in all analyzed periods. A correspondence analysis showed that L. paracasei, L. lactis, E. durans, E. faecium and L. mesenteroides are transversal in Serra da Estrela cheese manufacturing and were closely associated with milk, curd and cheese matrices. Additionally, L. casei, L. plantarum and L. curvatus were specifically associated with cheese matrices, possibly active during ripening and contributing for the development of these cheeses’ organoleptic characteristics.9814-6B05-9C03 | Ricardo Miguel Pereira Pintoinfo:eu-repo/semantics/publishedVersio

Conopídeos (Diptera: Conopidae) parasitando Centris (Heterocentris) analis (Fabricius) (Hymenoptera: Apidae, Centridini)

Parasites of adult bees are almost exclusively flies and the most important of them are conopids. This note registers for the first time the association of species of Physocephala (Diptera: Conopidae) with Centris (Heterocentris) analis (Fabricius). From 26 females and nine males of the host species found dead inside trap-nests on the campus of the University of São Paulo, Ribeirão Preto, Brazil, 35 parasitoids were obtained belonging to nine species of Physocephala. The data show that C. analis is a host to several conopid flies, and suggest that such parasitoids can play an important role in population control of this bee species.Parasitas de abelhas adultas são quase exclusivamente moscas e dentre os mais importantes estão os conopídeos. Nesta comunicação relata-se pela primeira vez a associação de espécies de Physocephala (Diptera: Conopidae) com Centris (Heterocentris) analis (Fabricius). De uma amostra de 26 fêmeas e nove machos da espécie hospedeira encontrados mortos em ninhos-armadilha vazios, no campus da Universidade de São Paulo, Ribeirão Preto, SP, emergiram 35 parasitóides pertencentes a nove espécies de Physocephala. Os dados mostram que C. analis é hospedeiro para várias espécies de conopídeos e sugerem que tais parasitóides podem desempenhar um papel importante na regulação populacional dessa espécie de abelha.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Os compostos isoprénicos da uva e o seu papel no aroma varietal do vinho

Determinados compostos presentes nas uvas são responsáveis pelo chamado aroma varietal dos vinhos. O termo “aroma varietal” não implica que cada casta tenha compostos voláteis específicos. De facto, um dado composto ou precursor aromático é, geralmente, encontrado nos mostos e vinhos de diferentes castas. O perfil aromático de cada casta é o resultado de uma combinação específica de vários compostos. De entre estes, os compostos terpénicos assumem um papel importante no aroma varietal dos vinhos, integrando um grupo químico mais vasto, designado compostos isoprénicos. A casta Moscatel destaca‑se por apresentar uma elevada fração de compostos terpénicos na forma livre (cerca de 50%). Outros compostos relacionados com o aroma varietal dos vinhos são as pirazinas, os norisoprenóides e os tióis.info:eu-repo/semantics/publishedVersio

Spatio-temporal variability of erosivity in Mato Grosso, Brazil

The impact of rainfall on surfaces lacking vegetal cover can dissociate soil particles, thereby initiating the erosion process. This is known as rainfall erosivity and is expressed by the R factor in the Universal Soil Loss Equation. Agricultural areas often show seasonally erosion susceptibility throughout the year due to oscillations of the soil exposure rate and the vegetation change. Considering that approximately 30 million ha of the Mato Grosso State in Brazil is used for agriculture, this study aimed to predict and map the spatial and temporal variability of its territory. We evaluated the monthly (EI30) and annual (R) erosivity for 158 rain gauge stations and spatialized the values of EI30 and R by the Kriging method. It was observed that R values ranked as very high in the north, and high and medium-high in the south of Mato Grosso state. The mean value is 8835 MJ mm ha-1 h-1 year-1, considered high. Ninety-one percent of the annual erosivity was concentrated in the period between October and April, corresponding to the rainy season. The highest R factor values were found in the macro-regions of the northwest, north, west and medium-north of Mato Grosso State

Análise microbiológica da qualidade de mortadelas fatiadas comercializadas em supermercados no município de Guanambi/Bahia

A mortadela é um derivado cárneo obtido por meio de uma emulsão cárnea de um ou mais espécies de animais de açougue, podendo ter ou não adição de toucinho, sendo um produto muito consumido pelo setor alimentício, principalmente, na forma fatiada servida em feiras livres, comércios e barracas de lanches, estando exposta a inúmeras fontes de contaminação. Diante disso, o presente trabalho tem por objetivo realizar uma análise microbiológica a fim de detectar a presença e/ou ausência de Shigella spp., Staphylococcus aureus, E. coli e Salmonella em mortadelas fatiadas comercializadas em supermercados no município de Guanambi/BA. As análises foram conduzidas no Laboratório de Microbiologia do Instituto Federal de Educação, Ciência e Tecnologia Baiano, Campus Guanambi, durante os meses de novembro a dezembro de 2021. Para Staphylococcus aureus, sete amostras apresentaram a formação de coágulo ou grumos, confirmando a presença deste microrganismo. Todas as amostras apresentaram contagem baixas para mesófilos. Foi detectado a presença de Salmonella em quatro supermercados e, de E. coli, em oito amostras. As amostras B e C dos supermercados 4 e 5 apresentaram contaminações inferiores a <3NMP/g para coliformes. Em fungos e leveduras, todas as amostras apresentaram baixa contaminação. Apenas as amostras 2C e 5B apresentaram em conformidade com a legislação vigente da ANVISA, as demais estão impróprias para o consumo devido a detecção da presença de Salmonella nas mesmas

Perception of the esthetic impact of mandibular incisor extraction treatment on laypersons, dental professionals, and dental students

Objective: To evaluate the degree of perception of laypersons, dental professionals, and dental students regarding dental esthetics in cases with mandibular central incisor extraction. Materials and Methods: Using a smile photograph of a person with normal occlusion and all teeth, modifications were made to reflect the extraction of a mandibular incisor of various compositions and sizes. For this purpose a program specifically for image manipulation (Adobe Photoshop CS3, Adobe Systems Inc) was used. After manipulation the images were printed on photographic paper, attached to a questionnaire and distributed to laypersons, dental professionals, and dental students (n = 90) to evaluate the degree of perception and esthetic using a scale of attractiveness, where 0 = hardly attractive, 5 = attractive, and 10 = very attractive. The differences between examiners were checked by the Mann-Whitney test. All the statistics were performed with a confidence level of 95%. Results: The results demonstrated the skill of the dental professionals and dental students in perceiving the difference between cases of normal occlusion and cases where an incisor was lacking (P < .05). The photograph in which the lateral incisors were shown to be larger than the central incisor was the one that obtained the highest value among the cases of extraction in all groups of evaluators. Conclusions: It can be concluded that dental professionals and dental students are more skillful at identifying deviation from normality. In addition, central incisor extraction should always be discarded when there are other treatment options available. (Angle Orthod. 2012;82:732-738.
