Ana Cristina Cesar le Drummond
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e ExpressãoO objeto de estudo deste trabalho é a marginália de Ana Cristina Cesar contida num exemplar do livro Reunião de Carlos Drumond de Andrade. Além de trazer a público um material manuscrito inédito, através da transcrição da marginália, pretende-se fazer uma reflexão crítica, enfocando a leitura como elemento produtor e tentando depreender conceitos de poesia, poema e poeta oriundos dessas anotações. Portanto, a essência desta análise é saber como Ana Cristina Cesar, lê Carlos Drumond de Andrade, o poeta consagrado
Differential stability of 2'F-ANA*RNA and ANA*RNA hybrid duplexes: roles of structure, pseudohydrogen bonding, hydration, ion uptake and flexibility
No full text14 pags., 7 figs., 3 tabs.Hybrids of RNA with arabinonucleic acids 2′F-ANA and ANA have very similar structures but strikingly different thermal stabilities. We now present a thorough study combining NMR and other biophysical methods together with state-of-the-art theoretical calculations on a fully modified 10-mer hybrid duplex. Comparison between the solution structure of 2′F-ANA•RNA and ANA•RNA hybrids indicates that the increased binding affinity of 2′F-ANA is related to several subtle differences, most importantly a favorable pseudohydrogen bond (2′F-purine H8) which contrasts with unfavorable 2′-OH-nucleobase steric interactions in the case of ANA. While both 2′F-ANA and ANA strands maintained conformations in the southern/eastern sugar pucker range, the 2′F-ANA strand's structure was more compatible with the A-like structure of a hybrid duplex. No dramatic differences are found in terms of relative hydration for the two hybrids, but the ANA•RNA duplex showed lower uptake of counterions than its 2′F-ANA•RNA counterpart. Finally, while the two hybrid duplexes are of similar rigidities, 2′F-ANA single strands may be more suitably preorganized for duplex formation. Thus the dramatically increased stability of 2′F-ANA•RNA and ANA•RNA duplexes is caused by differencesin at least four areas, of which structure and pseudohydrogen bonding are the most important. © The Author(s) 2010.

Admission Conditions and Graduates' Employability
No full textWe evaluate the information content of admission conditions for study programs’ quality by investigating its relationship with graduates’ employability. We find that study programs with larger numeri clausi are associated with a higher probability of finding a job. Additionally, compulsory admission exams seem to be informative about study programs’ quality. Namely, study programs requiring the Math exam appear to be linked with lower unemployment propensity. Cardoso et al. (2008), however, found that those programs face lower demand when compared to other studies. These paradoxical results suggest that students’ choices may be based on insufficient information on returns to higher education investment. That information failure indicates that a Government intervention may be due.higher education, unemployment propensity, fractional models
