Mixed methodology to analyze the relationship between maturity of environmental management and the adoption of green supply chain management in Brazil

The aim of this research is to verify the relationship between the maturity levels of environmental management and the adoption of green supply chain management (GSCM) practices by electro-electronic companies in Brazil. In this work a two-phase research was conducted, with one quantitative and the other qualitative. The quantitative phase aimed to test whether a relationship between the maturity levels of environmental management and GSCM exists, while the qualitative phase tried to detail the characteristics of this relationship. The quantitative phase was conducted through a survey with 100 Brazilian electro-electronic companies and the collected data were processed using Structural Equation Modeling. For the qualitative phase, a multiple case study was conducted with three companies located in Brazil. The results indicate that: (1) The main hypothesis was confirmed and considered statistically valid, indicating that, indeed, the maturity level of environmental management influences the adoption of GSCM practices; (2) a coevolution tends to occur between the environmental maturity and the GSCM practices; that is, the more developed is the company's environmental management, more complex GSCM practices are adopted; and (3) the GSCM internal practices tend to present a greater relative adoption than the external practices; these external practices of GSCM tend to be adopted when the company is inserted in a higher environmental stage and/or operates under a scenario of stronger normative environmental pressure. By the way, this is the first research mixing survey and case studies on GSCM in Brazil. (C) 2014 Elsevier B.V. All rights reserved.

Aplicações clássicas da técnica de espalhamento de raios-x a baixo ângulo em materiais nanoestruturados

The small angle X-ray scattering (SAXS) technique has been used with very much versatility and success in the structural characterization of nanostructured materials. The present work deals with a study of the principles of the SAXS technique and of some classical models employed in the structural characterization of nanostructured materials. Particularly, the study of the models and of the associated methodologies is applied to a set of samples of silica gels, of varied typical structures, prepared in the Laboratório de Novos Materiais of the Departamento de Física of the IGCE. The work discusses in an introductory chapter the principles of the SAXS technique and the foundation of classical models often used in the structural characterization of materials. The classical models and the associated methodologies were applied to a variety of silica gel structures. The studies include: i) the scattering from a system of particles - Guinier's law; ii) the asymptotic scattering from a two-phase system - Porod's law; iii) systematic deviation from Porod's law - Surface Fractal; iv) heterogeneities in solids with random size distribution - DAB Model; and v) the scattering from mass fractal structures. The analyses were carried out from experimental SAXS data obtained in several opportunities at the Laboratório Nacional de Luz Síncrotron (LNLS)

Análise microestrutural e propriedades mecânicas do aço DP 600

Seeking to meet the requirements: relatively low cost of materials and wide applicability in the automotive industry. The best option was the steel Dual Phase (DP), because that is lighter, have high formability, meet the cost requirements and applicability, steel Dual Phase (DP) came to meet these requirements with its two-phase microstructure, ferrite and martensite microstructure who claim to respect and mechanical properties. In this context, the aim of this study was to correlate the microstructure revealed in metallography to the mechanical properties observed in hardness and tensile tests. The microstructure is revealed by etching in 2% nital and then captured images of the sample were processed in ImageJ software to aid in determining the volume fraction of the phases present. Therefore, the mechanical properties were evaluated with respect to volume fraction of the steel layers and analyzed DP 600 together with the mechanical properties obtained by Rockwell hardness test and tensile test. With the values of the mechanical properties calculated and tested, it was possible to describe the method of metallography, as the attack phase and counts, so that it can use this relationship tested/calculated property as a qualitative analytical tool. The method used for the correlation between the microstructure and mechanical properties confirmed the importance of the phases present in the Dual Phase steel to obtain the desired mechanical properties in the application of the steel

Aparelho de Thurow modificado e aparelho ortodôntico fixo no tratamento da classe II com mordida aberta anterior

This work had aim to present two clinical cases with open bite Class II malocclusion that treated in the phase of the mixed dentition with the modified Thurow appliance and in the permanent dentition with fixed appliance. The dentoskeletal effects of these appliances were carefully analyzed with the aid of metallic implants inserted in both maxilla and mandible. The correction of the malocclusion and the improvement of the skeletal, dental and facial relationship were observed in both cases. The modified Thurow appliance followed by fixed-appliance as a two-phase treatment protocol revealed to be an effective treatment approach for the two young people that initially presented a Class II division 1 malocclusion associated to anterior open bite presented.

Nanostructured TiO2-based composites for light absorption

Metal oxidenanocomposites were prepared by two different routes: polyol and sol-gel. Characterization by X ray diffraction showed that the first processproducesdirectly a two-phase material, while the sol-gelpowder never showed second phase below 600 degrees C. Light spectroscopy of the treated powders indicated similarities for the processed materials. Although the overall material compositions are about the same, different structural characteristics are found for each processing. With the exception of Ti-Zn materials, all the double metal oxide powders showed higher absorbance than either TiO2 powder.

Pesquisa aplicada em comunicação: uma tendência necessária

The history of communication as a science was marked by different moments. The first one was built by technological experimentation and later, by language transformation. But the consolidation of communication as applied social science has come from theoretical research, when Lasswell and Lazarsfeld respectively proposed the hypodermic and the two-step flow theories. However, applied research – which involves experimentation and its observation in a practical application process – is once again being targeted by the academy. This text develops an essay on the importance of applied research to the development of contemporary communication, presenting examples and methods related to such reality.

Humanização da saúde: impacto de estratégias lúdicas e anímicas no estado de humor de trabalhadores do SUS

Humanization is a decisive factor for the positive conditions in the work environment related to the health sector, however, few initiatives take into consideration this aspect in different areas of knowledge, including the field of Human Kinetics. Thus, this study, which has a qualitative nature, aimed to identify the mood of employees from Sistema Únicos de Saúde - SUS, using evidences based on experiences of a playful and animistic activities. The study was conducted through bibliographical and exploratory research, using as a tool two-phase data collection the Brunel Questionnaire (BRUMS). Part of this study included an international sample compose of SUS participants from Araras city, having as criteria employees associated with SUS longer than one year. Participants experienced an animistic and recreational activities program and the instrument was applied before and after these experiences. Data was descriptively analyzed through the Thematic Content Analysis Technique. The results showed that the recreational and animistic activities can positively improve the mood of workers in the health sector, indicating the importance of developing new humanization strategies in health ambit. This study suggests new actions in public policy, able to encourage longer or even continuous interventions in the daily journey of health workers

Vivências anímicas e percepção subjetiva de qualidade de vida: perspectiva de servidores públicos nos âmbitos da saúde e da educação

This study was qualitative in nature and aimed to investigate the possible interference of spiritual experiences with the subjective perception of quality of life. The perspectives of civil servants in education and health services were compared. The study was developed through bibliographic and exploratory research, and the instrument used for data collection for the exploratory research was the WHOQOL-bref, which was applied in two stages: before and after experiences with spiritual activities. The purposive sample used in this study was composed of civil servants working in health and education administrative sectors of the Brazilian Unified Health System and a State University, respectively, with the intention of broadening the understanding about the perception of quality of life in civil servants from different sectors. The exploratory research of the study was carried out in three stages. The first was a two-phase data collection, before and after experiences with spiritual activities offered to civil servants who worked in the health care field, as well as the analysis of the results of this step. The second stage was the collection of data before and after experiences with spiritual activities offered to civil servants who worked in the administrative sector of education in a public university, besides the analysis of the results of this step. The third stage consisted of a comparison of the results obtained in the preceding two steps. The data resulting from the use of the research instrument for both samples were analyzed via Thematic Content Analysis. A questionnaire containing 26 questions based on four main themes was used. The first two questions were related to perceived quality of life and health satisfaction and they were not part of the specific domains. The other 24 questions were divided between the four themes: physical domain, psychological domain, domain of social relations, and environmental domain. The results...

Routing and Wavelength Assignment (RWA) with Power Considerations In All- Optical Wavelength-Routed Networks

Routing and wavelength assignment (RWA) is an important problem that arises in wavelength division multiplexed (WDM) optical networks. Previous studies have solved many variations of this problem under the assumption of perfect conditions regarding the power of a signal. In this paper, we investigate this problem while allowing for degradation of routed signals by components such as taps, multiplexers, and fiber links. We assume that optical amplifiers are preplaced. We investigate the problem of routing the maximum number of connections while maintaining proper power levels. The problem is formulated as a mixed-integer nonlinear program and two-phase hybrid solution approaches employing two different heuristics are developed
