This essay analyses the transmission of the texts of Shakespeare's final plays, Pericles, Coriolanus, Cymbeline, The Winter’s Tale, The Tempest, Henry VIII and The Two Noble Kinsmen, from author to censor to stage to print and argues that he had refined his writing, revision and collaborative practices.

The essay explores the socio-cultural role of the main academy in Parma, the Innominati (1574-1608), which flourished in the years when the Farnese dynasty was beginning to assert more forcefully its political control over the new state of Parma and Piacenza. The Innominati was from the start associated with the ruling dynasty, who must have recognized the importance of its cultural activities to strengthening their regime, particularly in the absence of a strong local university. This essay explores the institution’s contested position within the cultural landscape – as reflected also in its membership of courtiers, clergymen, and feudal aristocrats with more ambivalent relations with the Farnese. In particular, the focus falls on the theatrical activities of the group during the 1580s, a decade which saw the establishment of the Parma Index (1580) and the succession of the internationally celebrated Duke Alessandro Farnese (1587). Based on the little surviving evidence it is argued that the Academy in the 1580s became a creative hub for theatrical experimentation – through theoretical debate and composition, and possibly even performance. However, as relations between the Farnese and the local elites, especially feudal aristocrats, became more contested the Academy’s theatrical production and the public memory of this became increasingly controlled.

This work aims to analyze the relationship among culture, education and rhetoric on the sermons of the Priest Antonio Vieira (1608-1697). It discusses the presence of oratory on the Western teaching since its Greek origins until the formation of the Ratio Studiorum in 17th-century. Brazilian society is defined as baroque and the rhetoric arises as element essential in the elaboration of the social imaginary speeches and, occupying as an essencial element in the elaboration of discursese and social imaginaries, occupying the centre of controversies, about questions like reason and the faith, ethics and the politics, the nature of the Indian and African peoples, even over the own construction of the modern subject. In this context the vieira´s preaching discharges the functions of kerigma (preaching), didachê (education) and politics (action). The research consisted in a finicky reading over five of these sermons that were returned in the presence of different audiences. The pulpit was the cathedra where Vieira used his sermons as a manner of social mobilization that aimed not only teaching a determined knowledge of reality, but altering cruel situations like Indian and poor people slavery in his epoch. Education by Vieira consist in a tension between utopian hopes and urgencies of practice. The rhetorical tradition affirms the interdependence of technical ethics and politics aspects. To know is not enough is necessary to convince and to move, realizating passage from theorical to practical liverly. It presupposes still the preoccupation with the solidity of argumentation and of reasoning, a wide cultural formation, the requirement of a civic ethics and, mainly, the adequacy between content and the specifics of audience

We studied the energy and frequency dependence of the Fourier time lags and intrinsic coherence of the kilohertz quasi-periodic oscillations (kHz QPOs) in the neutron-star lowmass X-ray binaries 4U 1608−52 and 4U 1636−53, using a large data set obtained with the Rossi X-ray Timing Explorer. We confirmed that, in both sources, the time lags of the lower kHz QPO are soft and their magnitude increases with energy. We also found that: (i) In 4U 1636−53, the soft lags of the lower kHz QPO remain constant at∼30 μs in the QPO frequency range 500–850 Hz, and decrease to ∼10 μs when the QPO frequency increases further. In 4U 1608−52, the soft lags of the lower kHz QPO remain constant at 40 μs up to 800 Hz, the highest frequency reached by this QPO in our data. (ii) In both sources, the time lags of the upper kHz QPO are hard, independent of energy or frequency and inconsistent with the soft lags of the lower kHz QPO. (iii) In both sources the intrinsic coherence of the lower kHz QPO remains constant at ∼0.6 between 5 and 12 keV, and drops to zero above that energy. The intrinsic coherence of the upper kHz QPO is consistent with being zero across the full energy range. (iv) In 4U 1636−53, the intrinsic coherence of the lower kHz QPO increases from ∼0 at ∼600 Hz to ∼1, and it decreases to ∼0.5 at 920 Hz; in 4U 1608−52, the intrinsic coherence is consistent with the same trend. (v) In both sources the intrinsic coherence of the upper kHz QPO is consistent with zero over the full frequency range of the QPO, except in 4U 1636−53 between 700 and 900 Hz where the intrinsic coherence marginally increases. We discuss our results in the context of scenarios in which the soft lags are either due to reflection off the accretion disc or up-/down-scattering in a hot medium close to the neutron star. We finally explore the connection between, on one hand the time lags and the intrinsic coherence of the kHz QPOs, and on the other the QPOs’ amplitude and quality factor in these two sources.

An integrated instrument package for measuring and understanding the surface radiation budget of sea ice is presented, along with results from its first deployment. The setup simultaneously measures broadband fluxes of upwelling and downwelling terrestrial and solar radiation (four components separately), spectral fluxes of incident and reflected solar radiation, and supporting data such as air temperature and humidity, surface temperature, and location (GPS), in addition to photographing the sky and observed surface during each measurement. The instruments are mounted on a small sled, allowing measurements of the radiation budget to be made at many locations in the study area to see the effect of small-scale surface processes on the large-scale radiation budget. Such observations have many applications, from calibration and validation of remote sensing products to improving our understanding of surface processes that affect atmosphere-snow-ice interactions and drive feedbacks, ultimately leading to the potential to improve climate modelling of ice-covered regions of the ocean. The photographs, spectral data, and other observations allow for improved analysis of the broadband data. An example of this is shown by using the observations made during a partly cloudy day, which show erratic variations due to passing clouds, and creating a careful estimate of what the radiation budget along the observed line would have been under uniform sky conditions, clear or overcast. Other data from the setup's first deployment, in June 2011 on fast ice near Point Barrow, Alaska, are also shown; these illustrate the rapid changes of the radiation budget during a cold period that led to refreezing and new snow well into the melt season.
