Hence, this study contributes to understanding the existence and performance of QQH, by Interactions, according to the new models however, there is a lack of studies addressing this topic in suchĮnvironments. Incubators and STPs are favorable settings for Originality/value – Based on changes in the economic and social scenarios, new theoretical approachesĮmerge to explain the innovation process, such as the QQH. Quintuple helix does not have an actor that represents the environment, but STPs foster sustainable actions,Įncourage the generation of green companies and stimulate sustainable practices among established companies. Helix, but the example of associations and community centers as representatives of the civil society. Methodology and study object QQH representation, by identifying actor, performance and main results andĪdditional contributions to the QQH model.įindings – As a result, the authors noticed a lack of standardization on the representation of the quadruple Quintuple helix (QQH) in innovation environments such as incubators and science and technology parks (STPs).ĭesign/methodology/approach – The authors used the integrative review as a methodologicalĪpproach and systematized studies regarding the main research objectives theoretical approaches Purpose – The purpose of this paper is to investigate the literature on the representation of the quadruple and Quadruple Helix, Quintuple Helix, Innovation Habitats, Incubators, Science and Technology Parks Resumo Graduate Program in Business Administration, Federal University of Lavras Graduate Program in Business Administration, Federal University of Lavras, Lavras Graduate Program in Business Administration, Federal University of Itajuba, Itajuba All rights reserved.Andrea Aparecida da Costa Mineiro Mineiro PEI numeric values may contribute to differentiation between invasive and in situ breast carcinoma.īreast Breast neoplasms Carcinoma Ductal Intraductal Invasive Magnetic resonance imaging Noninfiltrating.Ĭopyright © 2014 Elsevier Ireland Ltd. The difference between IDC, DCIS and parenchyma were also considered highly statistically significant (p<0.0001) and so were the T/NT ratios for IDC and DCIS (10.1 ± 2.4 vs. The same applied to the differences in the group of patients with DCIS (428.0 ± 25.0 vs. IDC showed highly statistically different PEI numeric values compared to breast parenchyma (748.7 ± 32.2 vs. Analysis of variance (ANOVA) was used to test the differences between the mean PEI values of parenchyma, DCIS and IDC. The differences in PEI values between IDC and parenchyma and between DCIS and parenchyma were tested according to t-test. Tumor-to-non-tumor (T/NT) ratios were calculated for DCIS and IDC and compared. In the prospective trial, we analyzed the dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) of 60 consecutive patients with histologically confirmed unilateral DCIS (n=30) and IDC (n=30) and defined the PEI values (range mean ± SD) for the lesions and the breast parenchyma. The aim of this study was to contribute to the standardization of the numeric positive enhancement integral (PEI) values in breast parenchyma, ductal carcinoma in situ (DCIS) and invasive ductal carcinoma (IDC) and to evaluate the significance of the difference in PEI values between IDC and parenchyma, DCIS and parenchyma and IDC and DCIS.
