This article examines sustainability disclosures by the major banks in the Asia-Pacific region (the six largest banks from each of four countries: Australia, Japan, China and India) during the period 2005 to 2012. The findings show sustainability disclosures by banks that participate in the global reporting initiative (GRI) are significantly higher than disclosures by those banks that have not participated in the GRI. Amongst those banks that have participated in the GRI there is is a higher rate of disclosure by externally assured banks than by non-externally assured banks. Among the GRI

Birds represent the most diverse extant tetrapod clade, with ca. 10,000 extant species, and the timing of the crown avian radiation remains hotly debated. The fossil record supports a primarily Cenozoic radiation of crown birds, whereas molecular divergence dating analyses generally imply that this radiation was well underway during the Cretaceous. Furthermore, substantial differences have been noted between published divergence estimates. These have been variously attributed to clock model, calibration regime, and gene type. One underappreciated phenomenon is that disparity between fossil ages and molecular dates tends to be proportionally greater for shallower nodes in the avian Tree of Life. Here, we explore potential drivers of disparity in avian divergence dates through a set of analyses applying various calibration strategies and coding methods to a mitochondrial genome dataset and an 18-gene nuclear dataset, both sampled across 72 taxa. Our analyses support the occurrence of two deep divergences (i.e., the Palaeognathae/Neognathae split and the Galloanserae/Neoaves split) well within the Cretaceous, followed by a rapid radiation of Neoaves near the K-Pg boundary. However, 95% highest posterior density intervals for most basal divergences in Neoaves cross the boundary, and we emphasize that, barring unreasonably strict prior distributions, distinguishing between a rapid Early Paleocene radiation and a Late Cretaceous radiation may be beyond the resolving power of currently favored divergence dating methods. In contrast to recent observations for placental mammals, constraining all divergences within Neoaves to occur in the Cenozoic does not result in unreasonably high inferred substitution rates. Comparisons of nuclear DNA (nDNA) versus mitochondrial DNA (mtDNA) datasets and NT- versus RY-coded mitochondrial data reveal patterns of disparity that are consistent with substitution model misspecifications that result in tree compression/tree extension artifacts, which may explain some discordance between previous divergence estimates based on different sequence types. Comparisons of fully calibrated and nominally calibrated trees support a correlation between body mass and apparent dating error. Overall, our results are consistent with (but do not require) a Paleogene radiation for most major clades of crown birds.

This thesis developed a model of factors that influence meeting the needs of family with a relative admitted to an adult intensive care unit. The results from the model indicate that several variables are significant in meeting the needs of families in ICU. The factors identified in this study should be considered when planning future intervention studies or implementing interventions into ICU clinical practice. Meeting the needs of families is an integral part of caring for a critically ill patient. ICU staff can minimise this stressful time for relatives by anticipating and addressing family needs.
