A Insustentável Leveza do Marketing

Com o surgimento de novas e mais agressivas formas de concorrência potenciadas pela evolução tecnológica, em particular no que se refere ao desenvolvimento de sofisticados sistemas de informação e comunicação operando muitas vezes à escala planetária mas orientados para o indivíduo (a Internet é apenas um dos exemplos mais conhecidos), está-se a tornar claro que estratégias marketing baseadas na segmentação dos mercados, por mais inovadoras que sejam, são com frequência ineficazes face aos objectivos que se pretendem atingir. Começa assim a assumir uma importância crescente aquilo que se designa por marketing individualizado e das relações. O objectivo deste trabalho é evidenciar as principais implicações que este novo paradigma tem no domínio da gestão empresarial.

O impacto da automação da fenotipagem eritrocitária estendida na rotina de um serviço de hemoterapia

Objetivos. Avaliar o impacto da automação na fenotipagem eritrocitária expandida e o nível de concordância dessa com a metodologia manual em amostras de doadores de sangue atendidos no hemocentro coordenador da Fundação Hemopa no período de janeiro a dezembro de 2019. Material e Métodos. Foram analisadas 2.700 fenotipagens eritrocitárias realizadas por metodologia manual e automatizada através do equipamento IH500 da BioRad®. Os resultados foram testados quanto ao nível de concordância através do teste de Coeficiente Kappa. Resultados. Das amostras fenotipadas 98,6% (2.662/2.700) foram concordantes em ambas as metodologias e apenas 1,4% (38/2700) foram discordantes. Das 38 amostras discordantes 31,6% referiram-se ao fenótipo Lu(b); 15,8% ao fenótipo Lu(a); 13,1% ao fenótipo Fy(b); 7,9% aos fenótipos Le(b), E, c; 5,3% aos fenótipos N, S, s, Kp(a), P1; e 2,6% aos fenótipos M, Jk(a), Jk(b), Fy(a). Conclusões. O nível de concordância entre os dados obtidos através das técnicas de fenotipagem eritrocitária manual e automatizada foi de 98,6%. Já a implantação dessa metodologia teve um impacto positivo com o aumento em 1.649 amostras processadas a mais em relação ao mesmo período do ano anterior.Objective. Evaluate the impact of automation on expanded erythrocyte phenotyping and the level of agreement between it and the manual methodology in samples from blood donors treated at the blood center coordinating the Fundação HEMOPA from january to december 2019. Material and Methods. 2,700 erythrocyte phenotyping performed by manual and automated methodology using BioRad® IH500 equipment was analyzed. The results were tested for the level of agreement using the Kappa Coefficient test. Results. Of the phenotyped samples, 98,6% (2,662 / 2,700) were in agreement in both methodologies and only 1,4% (38/2700) were in disagreement. Of the 38 discordant samples, 31,6% referred to the Lu(b) phenotype; 15,8% to the Lu(a) phenotype; 13,1% to the Fy phenotype (b); 7,9% to Le(b), E, c phenotypes; 5,3% to N, S, s, Kp (a), P1 phenotypes; and 2,6% for phenotypes M, Jk(a), Jk(b), Fy(a). Conclusions. The level of agreement between data obtained through manual and automated erythrocyte phenotyping techniques was 98.6%. The implementation of this methodology had a positive impact, with an increase of 1,649 more processed samples compared to the same period of the previous year

Spatial patterns of leprosy in a hyperendemic state in Northern Brazil, 2001-2012

Objective: To describe the spatial patterns of leprosy in the Brazilian state of Tocantins. Methods: This study was based on morbidity data obtained from the Sistema de Informacoes de Agravos de Notificacao (SINAN - Brazilian Notifiable Diseases Information System), of the Ministry of Health. All new leprosy cases in individuals residing in the state of Tocantins, between 2001 and 2012, were included. In addition to the description of general disease indicators, a descriptive spatial analysis, empirical Bayesian analysis and spatial dependence analysis were performed by means of global and local Moran's indexes. Results: A total of 14,542 new cases were recorded during the period under study. Based on the annual case detection rate, 77.0% of the municipalities were classified as hyperendemic (> 40 cases/100,000 inhabitants). Regarding the annual case detection rate in < 15 years-olds, 65.4% of the municipalities were hyperendemic (10.0 to 19.9 cases/100,000 inhabitants); 26.6% had a detection rate of grade 2 disability cases between 5.0 and 9.9 cases/100,000 inhabitants. There was a geographical overlap of clusters of municipalities with high detection rates in hyperendemic areas. Clusters with high disease risk (global Moran's index: 0.51; p < 0.001), ongoing transmission (0.47; p < 0.001) and late diagnosis (0.44; p < 0.001) were identified mainly in the central-north and southwestern regions of Tocantins. Conclusions: We identified high-risk clusters for transmission and late diagnosis of leprosy in the Brazilian state of Tocantins. Surveillance and control measures should be prioritized in these high-risk municipalities

Business Plan: In or Out? A Holistic View of the Combination of Planning and Learning Processes when Evaluating Business Opportunities

Entrepreneurship is an important driver of innovation that is a critical factor to boost the competitiveness of modern economies. However, the rate of failure of start-ups tends to be quite significant. This chapter offers a new understanding of entrepreneurship inasmuch as a particular attention is given to different insights on the business plan in the creation of start-ups. In this context, we propose a broader understanding of the business plan integrating it in a holistic understanding of the business planning process. This investigation project results from the merits associated with the concomitant approach that combines planning and learning when creating new businesses. We support the adoption of this approach by developing a scheme that combines two processes that seem to be opposite. One focuses on the business planning and the other on the information collected from customers and other stakeholders. This scheme is likely to guide entrepreneurs and managers when they choose the concomitant approach that combines planning and learning over the other approaches previously studied. Furthermore, we also establish the foundation for future scientific research to develop a framework that can be used to help decrease the number of new businesses that do not survive in the market

Public policies on healthcare-associated infections: a Brazil and UK case study

To summarize the historical events and drivers underlying public policy for the prevention and control of healthcare-associated infections in Brazil and in the United Kingdom. In doing so, the article aims to identify lessons and recommendations for future development of public policy. The analysis is based on a historical overview of national healthcare-associated infections programs taken from previously published sources. Findings highlight how the development of healthcare-associated infections prevention and control policies followed similar trajectories in Brazil and the United Kingdom. This can be conceptualized around four sequential phases: Formation, Consolidation, Standardization, and Monitoring and Evaluation. However, while we identified similar phases of development in Brazil and the United Kingdom, it can be seen that the former entered each stage around 20 years after the latter
