This study examines the perceptions of directors in Australian public listed companies about their access to information for their role as directors. We focus on information costs and information asymmetry. Directors' perceptions of the relationship between the composition of Boards, the perceived roles of Boards and the information requirements to fulfil those roles were explored in interviews with 45 directors from public listed companies. Implicit in Agency Theory is the assumption that independent directors have free access to the information required to fulfil their role in monitoring and control. We found, however, demonstrable evidence of information asymmetry. The central finding was that directors perceive that the CEO and Executive have the controlling power over information. The provision of appropriate information for Board decisions is perceived to hinge on the "integrity" of the CEO and Executive. This emphasis on integrity and "good companies" does appear consistent with the Stewardship Theory of governance. It raises as a question for future research the possible alternative relationships between Boards and management. The directors interviewed discussed a range of strategies they used to keep themselves informed and made observations of additions to information that they believed should be available as a matter of course.

Due to restricted public access to military training fields such areas are quite interesting places for conducting faunistic research that would be simply impossible in other terrains. The area examined in the present study was the former military training field in Olsztyn, with the adjacent Lasek Pieczewski and the valley of Skanda Lake. The major aim of the study was to evaluate the current state of the environment in the terrain of the former military training field and the adjacent areas. In this study mites from the suborder Uropodina and cohort Labidostommatina (Acari: Mesostigmata et Prostigmata) were used as a bioindicators. These mites are useful for this purpose because of their specific habitat preferences. The community of mites in the area under scrutiny contained 23 taxa, comparing to 34 species found in whole voivoideship, which is 68% of local species biodiversity. Oodinychus ovalis turned out to be the most numerous species (the specimens of this species constituted almost 38% of the whole community and the frequency per sample was 55%). The other quite numerous species found in the examined area were Janetiella pulchella and Oodinychus karawaiewi, which constituted over 30% of the whole community. Taking into account the number of species and their habitat preferences two most valuable areas were found: southern part of Lasek Pieczewski and Skanda Lake valley.

The X-ray luminosity of black holes is produced through the accretion of material from their companion stars. Depending on the mass of the donor star, accretion of the material falling onto the black hole through the inner Lagrange point of the system or accretion by the strong stellar wind can occur. Cygnus X-1 is a high mass X-ray binary system, where the black hole is powered by accretion of the stellar wind of its supergiant companion star HDE226868. As the companion is close to filling its Roche lobe, the wind is not symmetric, but strongly focused towards the black hole. Chandra-HETGS observations allow for an investigation of this focused stellar wind, which is essential to understand the physics of the accretion flow. We compare observations at the distinct orbital phases of 0.0, 0.2, 0.5 and 0.75. These correspond to different lines of sight towards the source, allowing us to probe the structure and the dynamics of the wind.

INTEGRAL is one of the few instruments capable of detecting X-rays above 20 keV. It is therefore in principle well suited for studying X-ray variability in this regime. Because INTEGRAL uses coded mask instruments for imaging, the reconstruction of light curves of X-ray sources is highly non-trivial. We present results from a comparison of two commonly employed algorithms, which primarily measure flux from mask deconvolution (ii_lc_extract) and from calculating the pixel illuminated fraction (ii_light). Both methods agree well for timescales above about 10 s, the highest time resolution for which image reconstruction is possible. For higher time resolution, ii light produces meaningful results, although the overall variance of the lightcurves is not preserved.

<p>Parallel computing and steadily increasing computation speed have led to a new tool for analyzing multiple datasets and datatypes: fitting several datasets simultaneously. With this technique, physically connected parameters of individual data can be treated as a single parameter by implementing this connection directly into the fit. We discuss the terminology, implementation, and possible issues of simultaneous fits based on the Interactive Spectral Interpretation System (ISIS) X-ray data analysis tool. While all data modeling tools in X-ray astronomy in principle allow data to be fitted individually from multiple data sets, the syntax used in these tools is not often well suited for this task. Applying simultaneous fits to the transient X-ray binary GRO J1008–57, we find that the spectral shape is only dependent on X-ray flux. We determine time independent parameters e.g., the folding energy E_fold, with unprecedented precision.</p>
