Studies show that higher level diplomas make access to well-paid jobs easier and are an important source of prestige and social honor in Brazil. However, a broad literature today indicates a reduction of the importance of the diploma in hiring processes and argues that having a diploma becomes less and less sufficient for getting a job. This article examines the processes of selection of recently graduated engineers by eight large companies in the region of Campinas. Based on interviews with the main actors of the selection processes and on observation of the initial steps of a selection carried out by a consultancy company hired by one of the companies, the study shows that the weight of a diploma from a prestigious university is still the most important variable for the hiring decision, as it defines not only whether it will be possible to get the job or not, but also the access to vacancies that lead to better paid and more prestigious managerial positions. Finally, it discusses theoretical implications as well as what these results suggest in terms of public policies.

The copper and cadmium complexation properties in natural sediment suspensions of reservoirs of the Tietê River were studied using the solid membrane copper and cadmium ion-selective electrodes. The complexation and the average conditional stability constants were determined under equilibrium conditions at pH=6.00 ± 0.05 in a medium of 1.0 mol L-1 sodium nitrate, using the Scatchard method. The copper and cadmium electrodes presented Nernstian behavior from 1x10-6 to 1x10-3 mol L-1 of total metal concentration. Scatchard graphs suggest two classes of binding sites for both metals. A multivariate study was done to correlate the reservoirs and the variables: complexation properties, size, total organic carbon, volatile acid sulfide, E II and pH.

Antimicrobials, among other veterinary drugs, are used worldwide in industry and agriculture to protect animal health and prevent economic loss. In recent years, they have been detected in various environmental compartments, including soil, surface and groundwater and have become a topic of research interest. Emphasizing this class of compounds, this review presents the different pathways which veterinary drugs enter in the environment, in particular contaminate soils. Also are presented regulatory aspects and guidelines, adsorption/desorption and degradation of these compounds in soils and the consequences of its dispersal in the environment.

In the context of quality and good laboratory practices, the article recovers some historical data. From a specific Institutional situation (CPQBA/UNICAMP), is presented an experience of establishing and implementing a standard (NIT-DICLA-035) for good laboratory practice according to definitions of the Brazilian authority (INMETRO) responsible for regulating, monitoring, supervising and recognition in this area. The issue aims to focus on studies of pesticide residues in GLP parameters.

This article reports the results from the research work which objects the critical and profound study about the ADHD (Attention Deficit/Hyperactivity Disorder) in the courses for teachers' development in College Education, under its various dimensions - social, cultural, pedagogical, biological. The investigation focused on five adults with diagnosis for ADHD. The methodology used was the Case Study, developed from the Oral History as a source of data. The results that were obtained suggest that the study, proposed in the research, may contribute significantly for the teachers to know determining factors of the school performance of students with this disorder, as well as to guide them in the search of partnership with other professionals - doctors and psychologists, for example - when such partnership becomes necessary.
