Wealth reallocation and sustainability under climate change
No full textClimate change is often described as the greatest environmental challenge of our time. In addition, a changing climate can reallocate natural capital, change the value of all forms of capital and lead to mass redistribution of wealth. Here we explain how the inclusive wealth framework provides a means to measure shifts in the amounts and distribution of wealth induced by climate change. Biophysical effects on prices, pre-existing institutions and socio-ecological changes related to shifts in climate cause wealth to change in ways not correlated with biophysical changes. This implies that sustainable development in the face of climate change requires a coherent approach that integrates biophysical and social measurement. Inclusive wealth provides a measure that indicates sustainability and has the added benefit of providing an organizational framework for integrating the multiple disciplines studying global change.Peer reviewe

Forage selection by Masai giraffes (Giraffa camelopardalis tippelskirchi) at multiple spatial scales
No full textManagement of rangelands requires knowledge of forage species that are preferred or avoided by wildlife and livestock. A recent expansion of woody vegetation into previously open grasslands in African savanna ecosystems negatively impacts many mammalian grazers. Nevertheless, the ecological role of bush encroacher plant species as food may present a benefit for browsing species. We quantified diet selection by Masai giraffes (Giraffa camelopardalis tippelskirchi) through foraging observations and vegetation sampling in the Tarangire Ecosystem of Tanzania, which includes large areas of a native shrub that livestock managers have classified as an encroacher species (Dichrostachys cinerea). We compared woody plant species used by giraffes for foraging with availability at two different spatial scales during the wet and dry seasons. Giraffes selected some woody plants such as Vachellia species while significantly avoiding others, both at the local and landscape scales. Giraffes preferred foraging on D. cinerea at both spatial scales and in both the wet and dry seasons. Management that has focused on benefiting grazing livestock by removal of encroaching species (e.g., D. cinerea) may have unintended consequences for wildlife, especially for browsing species like giraffes that feed extensively on the expanding bush species

Children and Disasters: A tribute to Professor Kevin Ronan
No full text(c) The Author/sIn 1997, Professor Kevin Ronan published a paper in the first ever edition of the Australasian Journal of Disaster and Trauma Studies, titled “The Effects of a “Benign” Disaster: Symptoms of Post-traumatic Stress in Children Following a Series of Volcanic Eruptions”. Over the next 23 years, Kevin and his many colleagues pursued aspects of children and disasters to both improve practice and advance scholarship in this area. In March 2020 we were saddened by the untimely passing of Kevin. As a tribute to Professor Ronan this special issue of the Australasian Journal of Disaster and Trauma Studies brings together accounts of current research and practice initiatives inspired by, building upon, and directly influenced by Professor Ronan’s work
A Guide to Kevin Poelking's By the Hands That Reach Us
No full textThis thesis is written to accompany the full score of Kevin Poelking's By the Hands That Reach Us for wind symphony. The first chapter includes studies and expert opinions that attempt to define quality music. It begins with a brief synopsis of the recent (post World War II) increase of wind band repertoire and the difficulties that conductors encounter as a result. Quotations from conductors and composers throughout history are included in an attempt to shed light on the topic. The second chapter is a detailed biography of composer Kevin Poelking. It discusses personal, professional, and musical experiences that have shaped his compositional voice. There are also specific music examples given with explanations as to how they affected Poelking in his development as a composer. The final chapter is a detailed summary of Poelking's compositional process when writing By the Hands That Reach Us. The chapter includes original sketches, score excerpts, and specific compositional techniques that were used throughout the work
Continuous metadata flows for distributed multimedia
No full textThe practical use of temporal multimedia has increased markedly in recent years as enabling technologies for the distribution and streaming of media have become available. As a part of this trend, hypermedia systems and models have adapted accordingly to incorporate such distributed multimedia for presentation. Structured interpretation of information has long been a fundamental feature of both open hypermedia systems and knowledge systems. Metadata, in its many forms, has become the cornerstone for providing this structured knowledge above and beyond basic data and information. This thesis presents the rationale and requirements for continuous metadata, which supports the metadata accompanying distributed multimedia throughout the lifecycle of streamed media, from generation, through distribution, to presentation. Throughout this process it is the temporal and continuous nature of the metadata which is paramount. A conceptual framework for continuous metadata is proposed to encapsulate these principles and ideas. Continuous metadata and the associated framework enable the development, in particular, of real-time, collaborative, semantically enriched distributed multimedia applications. Experience building one such system using continuous metadata is evaluated within the framework. An ontology is developed for the system to enable the collation, distribution, and presentation of structure aiding navigation of multimedia, and it is shown how continuous metadata utilising the ontology can be distributed using multicas

Effects of climate and plant phenology on recruitment of moose at the southern extent of their range
No full textClimate plays a fundamental role in limiting the range of a species, is a key factor in the dynamics of large herbivores, and is thought to be involved in declines of moose populations in recent decades. We examined effects of climate and growing-season phenology on recruitment (8–9 months old) of young Shiras moose (Alces alces shirasi) over three decades, from 18 herds, across a large geographic area encompassing much of the southern extent of their range. Recruitment declined in 8 of 18 herds during 1980–2009, whereas others did not exhibit a temporal trend (none showed a positive trend). During those three decades, seasonal temperatures increased, spring–summer precipitation decreased, and spring occurred earlier, became shorter in duration, and green-up occurred faster. Recruitment was influenced negatively by warm temperatures during the year before young were born, but only for herds with declining recruitment. Dry spring–summers of the previous year and rapid rates of spring green-up in the year of birth had similar negative influences across declining and stable herds. Those patterns indicate both direct (yeart) and delayed (yeart−1) effects of weather and plant phenology on recruitment of young, which we hypothesize was mediated through effects on maternal nutritional condition. Suppressed nutrition could have been induced by (1) increased thermoregulatory costs associated with warming temperatures and (2) shortened duration of availability of high-quality forage in spring. Progressive reductions in net energetic gain for species that are sensitive to climate may continue to hamper individual fitness and population dynamics.This article is published as Monteith, Kevin L., Robert W.
