Quevedo, a Reader of the Classics. The Reconstruction of his Personal Library

[Resumen] Francisca Moya del Baño presenta en esta extensa monografía la labor de muchos años de estudio, en los que se dedicó a identificar los textos y ediciones de autores grecolatinos que Quevedo leyó, citó y explicó en su obra literaria, histórica y filosófica compuesta desde comienzos del siglo XVII hasta su muerte en 1645. Sus observaciones y comentarios renovarán sin duda la el trabajo realizado por los especialistas que han estudiado e interpretado el vasto corpus de Quevedo en las últimas décadas[Abstract] Francisca Moya del Baño presents in this extensive study her work of many years, in which she was dedicated to the identification of texts and editions of classical authors mentioned by Quevedo in the works he composed since the beginning of the seventeenth century until his death in 1645. Her observations and analyses will certainly renew the work of specialists who have been studying and interpreting Quevedo’s vast corpus in the last decade

The State of State Science Standards 2012

American science performance is lagging as the economy becomes increasingly high tech, but our current science standards are doing little to solve the problem. Reviewers evaluated science standards for every state for this report and their findings were deeply troubling: The majority of states earned Ds or Fs for their standards in this crucial subject, with only six jurisdictions receiving As.

Personal identity processes from adolescence through the late 20s : age trends, functionality, and depressive symptoms

Personal identity formation constitutes a crucial developmental task during the teens and 20s. Using a recently developed five-dimensional identity model, this cross-sectional study (N = 5834) investigated age trends from ages 14 to 30 for different commitment and exploration processes. As expected, results indicated that, despite some fluctuations over time, commitment processes tended to increase in a linear fashion. Exploration in breadth and exploration in depth were characterized by quadratic trends, with the highest levels occurring in emerging adulthood. Further, the functionality of these identity processes, and especially of exploration, changed over time. Exploration in breadth and exploration in depth were strongly related to commitment processes especially in adolescence and emerging adulthood, but these exploration processes became increasingly associated with ruminative exploration and depressive symptoms in the late 20s. Theoretical implications and suggestions for future research are outlined

Random Walks in Local Dynamics of Network Losses

We suggest a model for data losses in a single node of a packet-switched network (like the Internet) which reduces to one-dimensional discrete random walks with unusual boundary conditions. The model shows critical behavior with an abrupt transition from exponentially small to finite losses as the data arrival rate increases. The critical point is characterized by strong fluctuations of the loss rate. Although we consider the packet arrival being a Markovian process, the loss rate exhibits non-Markovian power-law correlations in time at the critical point.Comment: 4 pages, 2 figure

Temporal Correlations of Local Network Losses

We introduce a continuum model describing data losses in a single node of a packet-switched network (like the Internet) which preserves the discrete nature of the data loss process. {\em By construction}, the model has critical behavior with a sharp transition from exponentially small to finite losses with increasing data arrival rate. We show that such a model exhibits strong fluctuations in the loss rate at the critical point and non-Markovian power-law correlations in time, in spite of the Markovian character of the data arrival process. The continuum model allows for rather general incoming data packet distributions and can be naturally generalized to consider the buffer server idleness statistics
