Plano de ação para melhoria do clima organizacional de uma empresa do ramo da construção civil
No full textTCC (graduação) - Universidade Federal de Santa Catarina, Centro Sócio Econômico, Curso de Administração.0 presente trabalho acadêmico tem como propósito elaborar um Plano de Ação, baseado na Pesquisa de Clima Organizacional realizada em 2002, para ser adotado na Construtora Corbetta com intuito de alcançar os objetivos traçados. Para tanto, foi realizado um diagnóstico situacional onde entre outras coisas foram apresentados seus pontos fortes e fracos, focando especificamente os canteiros de obras da construtora estudada. De acordo com as fraquezas apresentadas foi definida a missão da empresa, formulado novos objetivos, estabelecidas as estratégias e elaborado o plano de ação propriamente dito. Devido a este procedimento, as Wes elaboradas conseguiram uma convergência plena com os objetivos da empresa. As constatações a que se chega o trabalho é a necessidade de uma análise financeira para conhecer a real possibilidade de algumas ações propostas, visto que a maioria delas não implica em gasto algum à empresa
Aportul lui Francisco Corbetta la evoluția chitarei baroce
No full textÎn Italia din perioada barocului chitara a devenit una dintre cele mai des folosite instrumente muzicale, fiind pe deplin încadrată în contextul social și cultural – carnaval, pastorală sau bal mascat. Apare o pliadă de muzicieni – interpeți și compozitori, care au contribuit considerabil la evoluția chitarei în spațiul european. Articolul dat are drept scop determinarea rolului chitaristului, profesorului și compozitorului din sec. al XVII-lea de origine italiană Francesco Corbetta în răspândirea chitarei cu cinci coarde în Franța, Anglia, Țările de Jos. Pe langă activitatea pedagogică și interpretativă prodigioasă desfășurată în curtea regelui Angliei, Charles al II-lea sau regelui Franţei, Louis al XIV-lea, F. Corbetta a elaborat manualele de chitară editate în diferite orașe ale Europei: De gli scherzi armonici (1639, Bologna); Varii capricii per la ghittara spagnuola (1643, Milano); Varii scherzi di sonate (1648, Bruxelles), La guitarre royale (1671, Paris). F. Corbetta a fost inventatorul unui stil distinctiv bazat pe îmbinarea scriiturii acordice cu ceea melodică, prin aceasta contribuind la afirmarea stilului omofon-armonic în muzica europeană. Sub aspect genuistic compozitorul pune în centrul repertoriului său suita de dansuri de curte de origini diferite: alemanda, curanta, giga, ciaccona, passacaglia ș.a

Abstract
RATIONALE:
Clusterin expression may change in various human malignancies, including lung cancer. Patients with resectable non-small cell lung cancer (NSCLC), including adenocarcinoma, have a poor prognosis, with a relapse rate of 30-50% within 5 years. Nuclear factor kB (Nf-kB) is an intracellular protein involved in the initiation and progression of several human cancers, including the lung.
OBJECTIVES:
We investigate the role of clusterin and Nf-kB expression in predicting the prognosis of patients with early-stage surgically resected adenocarcinoma of the lung.
FINDINGS:
The level of clusterin gradually decreased from well-differentiated to poorly differentiated adenocarcinomas. Clusterin expression was significantly higher in patients with low-grade adenocarcinoma, in early-stage disease and in women. Clusterin expression was inversely related to relapse and survival in both univariate and multivariate analyses. Finally, we observed an inverse correlation between Nf-kB and clusterin.
CONCLUSIONS:
Clusterin expression represents an independent prognostic factor in surgically resected lung adenocarcinoma and was proven to be a useful biomarker for fewer relapses and longer survival in patients in the early stage of disease. The inverse correlation between Nf-kB and clusterin expression confirm the previously reported role of clusterin as potent down regulator of Nf-kB
Beyond protest: issues and ideological inconsistencies in the voters of the Movimento 5 Stelle
No full textThe main goal of this chapter is to understand whether the voters of the 5 Stars Movement (M5S) are a chaotic assortment of individuals united only by their protest against the political establishment (or, at most, by a confused desire for change), or whether they share common values, a vision of democracy and fundamental political attitudes. The question is therefore whether we are faced with the complete ideological heterogeneity that typifies populist movements, or whether we can identify in the M5S electorate a significant level of political and ideological homogeneity. In the former case, we can expect a rapid decline of the movement, despite its incredible success in the 2013 general elections; in the latter case, we will try to trace the borders and discover the content of a new social and political entity that is potentially able to deeply influence Italian politics in the coming years
Physics-based modeling and data representation of pairwise interactions among pedestrians
No full textIn this work we study pedestrian-pedestrian interactions from observational experimental data in diluted pedestrian crowds. While in motion, pedestrians continuously adapt their walking paths trying to preserve mutual comfort distances and to avoid collisions. Leveraging on a high-quality, high-statistics data set, composed of several few millions real-life trajectories acquired from state-of-the-art observational experiments (about 6 months of high-resolution pedestrian tracks acquired in a train station), we develop a quantitative model capable of addressing interactions in the case of binary collision avoidance. We model interactions in terms of both long-range (sight based) and short-range (hard-contact avoidance) forces, which we superimpose on our Langevin model for noninteracting pedestrian motion [Corbetta, Phys. Rev. E 95, 032316 (2017)2470-004510.1103/PhysRevE.95.032316] (here further tested and extended). The model that we propose here features a Langevin dynamics with fast random velocity fluctuations that are superimposed on the slow dynamics of a hidden model variable: the intended walking path. In the case of interactions, social forces may act both on the intended path and on the actual walked path. The model is capable of reproducing quantitatively relevant statistics of the collision avoidance motion, such as the statistics of the side displacement and of the passing speed. Rare occurrences of actual bumping events are also recovered. Furthermore, comparing with large data sets of real-life tracks involves an additional computational challenge so far neglected: identifying automatically, within a database containing very heterogeneous conditions, only the relevant events corresponding to binary avoidance interactions. In order to tackle this challenge, we propose a general approach based on a graph representation of pedestrian trajectories, which allows us to effectively operate complexity reduction for efficient data classification and selection
Robust optimization of the heteroextractive distillation column for the purification of water/acetic acid mixtures using p-xylene as entrainer
No full textThe separation of water and acetic acid mixtures is a challenging task in the terephthalic acid production process. This study addresses the techno-economical optimization of an heteroextractive distillation column that uses p-xylene as entrainer. The optimization of this column is performed by means of robust optimizers belonging to the BzzMath library, coupled with the detailed process simulation of the downstream section performed with the commercial software SimSci PRO/II. A comparison with respect to the commercial simulator optimizer and a quantification of benefits are given. Results show that the BzzMath robust optimizer reaches a lower Total Annual Cost (−3.5%) with respect to the commercial software optimization. Finally, the comparison with other entrainers proposed in literature for the advanced distillation of the water/acetic acid mixtures demonstrates the economical and operational appeal of this process configuration
