Cost-effectiveness of the tools for donors recruitment

A sociedade tem se tornado cada vez mais instruída e exigente, na qual os clientes possuem grande influência nas estruturas da organização, fazendo com que as empresas busquem aumentar a satisfação dos clientes, atendendo-os de modo a superar as suas expectativas. Nesse contexto, estão inseridos os doadores de sangue. No Brasil, a lei que regulamenta o funcionamento dos serviços hemoterápicos preconiza que a doação de sangue deve ser um ato voluntário e altruísta, no qual o doador não deve receber nenhum tipo de vantagem para realizar a doação de sangue. Segundo dados da Coordenação Geral de Sangue e Hemoderivados, no ano de 2014, a região Sudeste, na qual está concentrada a maior parte da população brasileira, registrou uma das menores taxas de doação: a cada 1.000 habitantes, apenas 17,22 % doaram sangue. É fundamental para os hemocentros identificarem a maneira mais convincente e estimulante de convocar/captar doadores de sangue, de modo a manter os estoques suficientes, além de atender os doadores conforme suas expectativas. Portanto, o objetivo desse estudo foi avaliar qual a ferramenta de abordagem individual e coletiva que apresenta o melhor custoefetividade somado à preferência dos doadores, a qual será essencial para o aumento do número de doações. Para isso, os dados utilizados abrangem um período de 4 anos (2012 a 2015) e representam o número de candidatos à doação de sangue de duas instalações do Hemocentro RP, ambos localizados na cidade de Ribeirão Preto (Sede e Posto de Coleta). Valores-p para o teste de Dickey e Fuller de estacionariedade sugerem que as séries analisadas não são estacionárias, sendo então diferenciadas, passando a apresentar p<0,01. Foi observado que existe correlação (p = 0,31) entre o número de malas diretas e o retorno dos doadores seis meses após o envio das mesmas. No Posto de Coleta, não foi constatada essa correlação. Além disso, as ferramentas para captação que trabalham com os doadores de reposição apresentaram melhores resultados, tais como as ferramentas com atendimento mais personalizado (contato telefônico) juntamente com as campanhas realizadas pelo Facebook Inc.Society has become increasingly educated and demanding, in which the customers have a strong influence on the organization\'s structures, causing companies to seek to increase the customer satisfaction, meeting them in a way that exceeds their expectations. In this context, blood donors are inserted. In Brazil, the law that regulates the operation of hemotherapy services recommends that blood donation should be a voluntary and altruistic act in which the donor should not receive any type of advantage in order to donate blood. According to data from the \"Coordenação Geral de Sangue e Hemoderivados\", in 2014, the Southeast region, where most of the Brazilian population is concentrated, had one of the lowest rates of donation: for every 1,000 inhabitants, only 17.22% donated blood. It is essential for blood centers to identify the most convincing and stimulating way to recruit and invite blood donors, to maintain sufficient stocks by serving donors according to their expectations. Therefore, the aim of this study was to evaluate which tool of individual and collective approach presents the best cost-effectiveness besides to donor preference, which will be essential for increasing the number of donations. To do so, the data cover a period of 4 years (2012 to 2015) and represent the number of candidates for blood donation from two Hemocentro RP facilities, both located in the city of Ribeirão Preto (\"Sede\" and \"Posto de Coleta\"). p-values for the test of Dickey and Fuller of stationarity suggest that the series analyzed are not stationary, being then differentiated, with p <0.01. It was observed that there is a correlation (p = 0.31) between the number of direct mailings and the donors return six months after sending them. No correlation was verified at the \"Posto de Coleta\". Moreover, recruitment tools for replacement donors present better results, such as the tools with more personalized service (telephone contact) along with the campaigns carried out by Facebook Inc

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora

Growing knowledge: an overview of Seed Plant diversity in Brazil

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
