INOVAÇÃO NO MODELO DE GESTÃO PARA A MICRO E PEQUENA EMPRESA

No Brasil as micros e pequenas empresas caracterizam-se pela administração não profissional e gestão pessoal, insuficiência de recursos, principalmente financeiros e falta de mão-de-obra qualificada. Todavia, para serem competitivas e se manterem no mercado necessitam atualizar-se permanente e sistemáticamente, em termos de gestão e livrar-se de atividades com baixo valor agregado. Nesse contexto, tais empresas convivem com a necessidade imperiosa de focar seus modelos de gestão na inovação, contudo sem depender de onerosos investimentos, à semelhança das grandes empresas. Diante disso, investigou-se  mediante uma pesquisa exploratória e bibliográfica de que forma a inovação pode se converter em uma ferramenta de gestão que produza diferencial competitivo para a micro e pequena empresa. Dentre as principais constatações resultantes, desponta a que indica a necessidade de desmistificar a inovação e de extendê-la à toda a economia e não apenas a determinados setores, grupos ou segmentos econômicos. É preciso que a inovação alcance, sem estardalhaço, nichos de micros e pequenas empresas de forma sistemática e persistente, contribuindo efetivamente para a solidez e sustentabilidade dos empreendimentos empresariais. Nessa empreitada, sugere-se a adoção de um modelo de gestão baseado em processo de inovação contínuo, mediante a utilização da técnica de benchmarking.

Macular phototoxicity after corneal cross-linking

Purpose: To assess potential vascular, structural, and functional changes to the macula in patients with keratoconus that underwent ultraviolet A (UVA)-riboflavin-mediated corneal collagen cross-linking (CXL) therapy. Patients and methods: Seventeen eyes from 17 patients of age 16 years or older with keratoconus undergoing CXL treatment were studied. The same eye served as its own control (before CXL vs after CXL). Eyes were evaluated in terms of best-corrected visual acuity (BCVA), refractive error, intraocular pressure, Amsler grid, retinography, fluorescein angiography, autofluorescence, and spectral domain optical coherence tomography (SD-OCT) prior to CXL and 7 and 30 days after treatment. Multifocal electroretinography (mfERG) was recorded prior to and 7 days after CXL. Results: Mean (SD) BCVA by logMAR chart was 0.47 (+/-0.12) pre-CXL, 0.55 (+/-0.15) 7 days post-CXL (P=0.57), and 0.46 (+/-0.10) 30 days post-CXL (P=0.87). Mean (SD) SD-OCT central macular thickness (microm) was 253.62 (+/-20.9) pre-CXL, 260.5 (+/-18.7) 7 days post-CXL (P=0.48), and 256.44 (+/-21.6) 30 days post-CXL (P=0.69). In 12 eyes, mfERG revealed a statistically significant increase (P=0.0353) in P1 latency (ms) of ring four from the pre-CXL period (39.45+/-2.05) to 7 days post-CXL (41.04+/-1.28) period. Regression analysis showed that the increase in P1 latency was correlated with the increase in central macular thickness (P=0.027). Furthermore, nine patients experienced a significant decrease in P1 amplitudes of rings 1 (P=0.0014), 2 (P=0.0029), 3 (P=0.0037), 4 (P=0.0014), and 5 (P=0.0012) from pre-CXL to 7 days post-CXL. Conclusion: In this pilot study, most of the patients exhibited slight changes in their mfERG parameters and OCT thickness, despite a lack of vascular abnormalities observed on fluorescein angiography/autofluorescence imaging, no alteration in BCVA, and no reports of symptoms. These changes could, therefore, be categorized as a mild subclinical effect of the corneal cross-linking procedure

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others
