Os desafios da gestão da qualidade numa universidade pública brasileira: a experiência da Unicamp

This paper presents Unicamp's experience, with regard to its institutional evaluation and strategic planning processes since the 2000s, from two perspectives: the recommendations by the external committees and the analysis of the perception of the internal committees. A critical analysis of the Sinaes and State Council of Education of São Paulo model is presented. Public documents referring to five cycles show that the evaluation processes have become more comprehensive although operational limitations still restrict the evaluation amplitude. Through questions present in both AI/2009-20013 and AI/2014-2018 instruments, sensed the perception of the internal community regarding to the importance of the evaluation and the planning demonstrating a gradual integration between both processes. Neste artigo, apresenta-se a experiência da Unicamp nos processos de avaliação institucional e de planejamento estratégico, a partir dos anos 2000, sob duas perspectivas: das recomendações pelos comitês externos e da análise da percepção das comissões internas. Apresenta-se, também, uma análise do Sinaes e do modelo do Conselho Estadual de Educação de São Paulo. Documentos referentes aos cinco ciclos mostram que os processos se tornam mais abrangentes, mas há limitações operacionais, que restringem a amplitude da avaliação. As questões formuladas às comissões internas de cada órgão avaliado, nos processos AI/2009-20013 e AI/2014-2018, prospectou a percepção da comunidade sobre a importância da avaliação e do planejamento decorrente dela, mostrando gradativa integração entre os mesmos

White emission in polymer light-emitting diodes: color composition by single-layer electroluminescence and external photoluminescence component

White emitting devices were obtained through a single component system by combining two materials with different emission properties: a greenish electroluminescent polymer, known as poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt-co-(9,9-di-{5׳-pentanyl}-fluorenyl-2,7-diyl)] (PFOFPen), embedded in a diode-like structure (ITO/PEDOT-PPS/PFOFPen/Ca/Al) and a photoluminescent red-emitting material, poly[2-methoxy-5-(3′,7′-dimethyloctyloxy)-1,4-phenylenevinylene] (MDMO-PPV). A thin film of the red emitter component (MDMO-PPV) was deposited on a quartz plate and mounted on the opposite face of the glass/ITO substrate. The white color composition (0.35, 0.31) was obtained based on trivial photophysics processes: MDMO-PPV partially absorbs the higher energy electroluminescence (EL) emission coming from the PFOFPen-diode, decaying radiatively and emitting red light via photoluminescence (PL), matching with the transmitted greenish light. White emission is thus accomplished by choosing the proper materials with overlapped absorption spectra, adjusting the absorbance ratio by changing the MDMO-PPV layer film thickness, and the lower energy PL intensity until reaching the CIE white coordinates.FAPESPCNPqINCT-INEO (MCTI/CNPq/FAPESP)UNICAMP/FAEPE

Host/Guest Simulation of Fluorescent Probes Adsorbed into Low-Density Polyethylene, 1. Excimer Formation of 1,3-Di(1-pyrenyl)propane

Molecular dynamics and Rotational Isomer State/Monte Carlo techniques with a Dreiding 1.01 Force Field are employed to study the excimer formation of isolated 1,3-di(1-pyrenyl)propane and the probe adsorbed into a low-density polyethylene (LDPE) matrix model. The probability of formation of each molecular conformer at several temperatures was calculated using these theoretical techniques. Conformational statistical analysis of the four torsion angles (ϕ₁, ϕ₂, θ₁, θ₂) of Py3MPy showed that the angles —C—Cᵃʳ— (ϕ₁, ϕ₂) present two states c ± = ±90°; and the angles —C—C— (θ₁, θ₂), the three trans states = 180°, g ± = ±60°. The correlation of θ₁–θ₂ torsion angles showed that the most probable pairs were g⁺g⁻ and g⁻g⁺ for the excimer-like specimens, although these angles are distorted because of interactions with the polymer matrix. The temperature dependence of the excimer-formation probability revealed that this process was thermodynamically controlled in the isolated case. When the probe was adsorbed into the LDPE matrix, the excimer formation process was reversed at T = 375 K. At T > 375 K, the behavior was similar to the isolated case but, at T < 375 K, excimer formation probability increased with temperature as found experimentally by steady-state fluorescence spectroscopy. This temperature was coincident with the onset of the LDPE melting process, determined experimentally by thermal analysis.The authors wish to thank Brite EuRam programme (BE97-4472) and CAM (07N/0002/1998) for support

Micromorphology and Relaxation Processes of Low Density Polyethylene Probed by Fluorescence Spectroscopys

Fluorescence spectra of molecular guests at several temperatures are useful technique to study several types of polymer properties. In particular, it has been often employed to study polymer relaxation processes either in static or in dynamic conditions. In this work some applications of the steady-state fluorescence spectroscopy of different guests in polyethylene and in particular reports the photophysical behavior of 1,3-di(1-pyrenyl)propane (1Py(3)1Py) sorbed in low density polyethylene are shown. This molecular probe differs of pyrene by its ability to form intramolecular excimer species and we discuss the temperature dependence of this formation. In this study we recorded simultaneously the fluorescence spectra and the differential scanning calorimetry (dsc) traces. The relative dependence of fluorescence intensities on temperature of the higher energy vibronic band at 367 nm, of the isolated choromophore emission and of the excimer emission were discussed and associated with the polyethylene polymer relaxation processes. The influence of the macroscopic stretching upon the polymer relaxation processes and the fluorescence emission was also investigated and compared with previous results.J.

Photochemical sensing of semicrystalline morphology in polymers: Pyrene in Polyethylene

Pyrene was inserted into a low-density polyethylene matrix. Fluorescence spectra as a function of temperature and the differential scanning calorimetry (DSC) trace were recorded simultaneously. Along with the usual vibronic bands, a low-intensity band at 365 nm appears at higher energies with respect to the 0−0 transition in the pyrene fluorescence spectra. The fluorescence intensity of this small band increased with temperature, and an isoemissive point was observed to occur at 368 nm. This emission was interpreted as arising from pyrene molecules located in the outer rigid interfacial region of polymer crystallites. Its temperature-dependent fluorescence was interpreted in terms of electron−phonon coupling; two phonons which coincide with fundamental vibrations of polyethylene were necessary to fit experimental data. Coupling with a high-energy phonon was possible at low temperature, whereas, above the β relaxation temperature, phonon coupling occurs with a lower-energy phonon. The α relaxation was detected as a maximum in fluorescence intensity since above its characteristic temperature, nonradiative processes begin to operate.J.

Tuning emission colors from blue to green in polymeric light-emitting diodes fabricated using polyfluorene blends

The photo- and electroluminescent properties of single-layer two-component blends composed of one blue emitter polymer and one green emitter polymer were studied. The blue emitter, poly[(9,9-dioctylfluorenyl-2,7- diyl)-alt-co-(9,9-di-{5′-pentanyl}-fluorenyl-2,7-diyl)] (PFOFPen), was used as the matrix, and the green emitter, poly[(9,9-dihexylfluorenyl-2,7-diyl)-alt-co- (bithiophene)] (F6T2), was used as the guest. The F6T2 content in the blends varied from 0.0075 wt % to 2.4 wt %. Remarkable differences were observed between the electroluminescent (EL) and photoluminescent (PL) spectra of these blends, which indicated that the mechanism for excited-state generation in the former process had a higher efficiency in the aggregated phase than in the nonaggregated phase. Blending these two polymers gradually tuned the emission color from blue (PFOFPen and blends with <0.75 wt % F6T2) to green (F6T2 and blends with >0.75 wt % F6T2). The photophysical processes involved in both EL and PL emission are also discussed.FAPESP (12/23460-4; 13/16245-2)CNPqINCT-INEO (MCTI/CNPq/FAPESP)UNICAMP/FAEPE

De-aggregation of a polyfluorene derivative in clay nanocomposites: a photophysical study

The de-aggregation of a very luminescent polyfluorene derivative poly(9,9-di-hexylfluorenediyl divinylene-alt-1,4-phenylenevinylene), which has a high tendency to π-stacking aggregation was achieved through the interaction of the polymer with clay in clay/polymer nanocomposites. The mixing of diluted toluene polymer solutions with kaolinite was enough to promote the de-aggregation, even without the indication of polymer intercalation, indicating that the polymer de-aggregation was obtained due to its interactions with clay platelet surfaces. The photoluminescence observed for the dispersed polymer on clays showed an increase in intensity and a blue-shift of the photoluminescence, when compared with pure pristine material in thin film form. The results presented bring the possibility to produce more efficient polymer based devices and to carry single molecule studies using nanocomposite film formation

PLANEJAMENTO ESTRATÉGICO EM INSTITUIÇÕES UNIVERSITÁRIAS: DESAFIOS DA UNIVERSIDADE PÚBLICA

Este texto relata as dificuldades para implantação da gestão estratégica na Universidade Estadual de Campinas e descreve alguns dos resultados já alcançados como fruto de projetos vinculados ao Planejamento Estratégico, mostrando as múltiplas possibilidades de avanço na gestão. A metodologia utilizada foi baseada em elementos do Planejamento Estratégico Situacional – PES (MATUS, 1993) e do Balance Scored Card – BSC (KAPLAN; NORTON, 1997). Esse modelo adaptado também combinou elementos da metodologia Problem-Driven Iterative Adaptation – PDIA (PRITCHETT, 2017), método de implantação de soluções direcionadas aos grandes problemas definidos localmente e definidos no desempenho (em oposição ao transplante de soluções de “melhores práticas” preconcebidas e empacotadas). Disto resultaram o Mapa Estratégico, a Cadeia de Valor, projetos estratégicos e a implantação de uma ferramenta de Gestão de Projetos para a realização do monitoramento dos mesmos. A conclusão é que as principais dificuldades na implantação da Gestão Estratégica estão relacionadas com a falta de cultura dos órgãos administrativos em organizar e priorizar as atividades e projetos para melhor responderem às demandas dos usuários. Esta falta de cultura engloba também os aspectos relacionados com a ausência de metas e de indicadores de eficiência na gestão

Gestão estrategica em instituições universitárias: desafios da universidade pública/ Strategic management in university institutions: public university challenges

Este texto relata a implantação da gestão estratégica na Universidade Estadual de Campinas e descreve alguns dos resultados já alcançados através da execução dos projetos estratégicos, mostrando as múltiplas possibilidades de avanço na gestão. A metodologia utilizada foi baseada em elementos do Planejamento Estratégico Situacional – PES (MATUS, 1993) e do Balance Scored Card – BSC (KAPLAN; NORTON, 1997). Esse modelo adaptado também combinou elementos de metodologia que propõe que as soluções sejam construídas focando nos grandes problemas e nas circunstâncias locais, ao invés de transplantar soluções e “melhores práticas” preconcebidas e empacotadas que foram criadas para outros ambientes. Os principais produtos desse processo foram a redefinição da Identidade Organizacional, o reconhecimento das 4 grandes Áreas Estratégicas e das 13 Estratégias Corporativas, a elaboração do Mapa Estratégico e da Cadeia de Valor, a definição dos Projetos Estratégicos e a criação da sistemática de Gestão de Projetos. Na implantação de uma Gestão Estratégica, importantes desafios enfrentados estão relacionados com a falta de cultura dos gestores e administradores em processos estruturados de planejamento, bem como com a ausência de metas e de indicadores de eficiência na gestão. Tornou-se possível compreender com clareza os benefícios e as virtudes do Ciclo da Gestão Estratégica para a universidade através da integração dos macroprocessos de gestão e governança
