The CSR landscape: an overview of key theoretical issues and concepts

Questioning the way the business enterprise operates in contemporary society has become an established field of investigation. In the current global debate, corporate social responsibility (CSR) - and other terms that are linked to it such as sustainability and corporate citizenship - tend to be as much about semantics as substance. Therefore, the key to this book is the fundamental idea that drivers for change should be found primarily within the heart of organizations and expressed through various implementation strategies. As long as organizations are not embracing CSR as a fundamental element in business continuity, it will remain a mixture of semantics, avoidance, compliance and social philanthropy. This book captures and distils emerging implementation perspectives in terms of theory and practice in one concise volume and will help to unravel and demonstrate the possible changes and consequences of the adaptation of CSR

Landscape characteristics associated with species richness and occurrence of small native mammals inhabiting a coastal heathland: a spatial modelling approach

In the coastal region of south-western Victoria, Australia, populations of native small mammal species are restricted to patches of suitable habitat in a highly fragmented landscape. The size and spatial arrangement of these patches is likely to influence both the occupancy and richness of species at a location. Geographic Information System (GIS)-based habitat models of the species richness of native small mammals, and individual species  occurrences, were developed to produce maps displaying the spatial  configuration of suitable habitat. Models were generated using either generalised linear Poisson regression (for species richness) or logistic regression (for species occurrences) with species richness or  presence/absence as the dependent variable and landscape variables, extracted from both GIS data layers and multi-spectral digital imagery, as the predictor variables. A multi-model inference approach based on the Akaike Information Criterion was used and the resulting model was applied in a GIS framework to extrapolate predicted richness/likelihood of occurrence across the entire area of the study. A negative association between species  richness and elevation, habitat complexity and sun index indicated that richness within the study area decreases with increasing altitude, vertical vegetation structure and exposure to solar radiation. Landform  characteristics were important (to varying degrees) in determining habitat occupancy for all of the species examined, while the influence of habitat complexity was important for only one of the species. Performance of all but one of the models generated using presence/absence data was high, as indicated by the area under the curve of a receiver-operating characteristic plot. The effective conservation of the small mammal species in the area of concern is likely to depend on management actions that promote the protection of the critical habitats identified in the models.

Are the earliest field monuments of the pacific landscape serial sites?

Explanations of the origin and genesis of Pacific field monuments commonly assume they reflect local social change in islands or island groups which were increasingly isolated following colonization. A recent review of early West Polynesian archaeology suggests that the penecontemporaneous appearance of various kinds of field monuments from eastern Melanesia to Polynesia may be better explained as evidence of interaction and the movement of people and/or ideas, possibly associated with the colonization of East Polynesia.

Determining the professional sport broadcasting landscape : an Australian football club perspective

The professional sport broadcasting landscape has received much attention from an economic and legal perspective. While the economic and legal focus has been the predominant association with sport broadcasting, there has been little research undertaken into the breadth of delivery and significance of broadcast coverage. The aim of this paper was to identify the professional sport broadcasting landscape in Australia. The sport broadcast landscape was examined from the perspective of two professional football codes. In-depth interviewing of senior managers of 11 AFL, and 10 NRL clubs was undertaken with the resulting data analysed, coded and emergent themes identified. Three core themes emerged: identified as territory, distribution and profile. A further seven sub-themes specific to the outcomes associated within each category were also identified. Major findings highlight the territorial nature of the Australian professional football league market, identifying the way in which clubs are representative of particular regions. Issues associated with free-to-air delivery, brand recognition and core market attributes were also identified. Results are presented; implications for management and opportunities for future research are discussed.

A knowledge-based economy landscape: implications for tertiary education and research training in Australia

This paper discusses the higher education sector’s role in knowledge-based economy though research training, that is, doctoral education. It also examines how a Faculty of Education supports its doctoral candidates in their endeavours to become ‘knowledge producers’. Two themes are explored: one is Australia’s limited investment in education by international standards; and the other is the research training needs and circumstances of doctoral candidates who are located in professional and workplace contexts. The paper discusses the role of online support and a Doctoral Studies in Education (DSE) online seminar program to support primarily off-campus, part-time mid-career professionals. These are typical of many of Australia’s doctoral candidates. E-learning is examined as part of a comprehensive support and research training strategy for doctoral candidates studying at a distance. We discuss the sorts of opportunities and experiences our candidates receive and the extent to which they are readied to work effectively in a knowledge-based economy.

Nest-tree selection by the threatened brush-tailed phascogale (phascogale tapoatafa) (marsupialia: dasyuridae) in a highly fragmented agricultural landscape

The conservation of roosting and nesting resources is of critical concern for many hollow-dependent species around the world. We investigated the nest-tree requirements of the threatened brush-tailed phascogale (Phascogale tapoatafa) in a highly cleared agricultural landscape in south-eastern Australia. We documented the physical characteristics of selected nest trees and describe the spatial and temporal patterns of nest-tree use as revealed by radio-tracking. Nine phascogales (seven females, two males) were radio-tracked between March and July 1999 in an area where most woodland habitat is confined to linear strips along roads and streams or small patches and scattered trees in cleared farmland. Female phascogales were monitored for 13–35 days over periods of 5–15 weeks and two males were monitored for 2 and 9 days respectively. A total of 185 nest-tree fixes was collected and all nests occupied by phascogales were in standing trees. Eighty-three nest trees were identified, ranging in diameter at breast height (dbh) from 25 to 171 cm, with a mean dbh for the trees used by each individual phascogale of >80 cm. Phascogales did not discriminate between canopy tree species in selecting nest trees, but showed highly significant selection for trees in the largest size class. All individuals used multiple nest trees, with the seven females occupying an average of 11.4 nest trees from a mean of 25 diurnal locations. The number of nest trees continued to increase throughout the study, suggesting that more would be identified during a longer or more intensive study. Occupied nest trees were located throughout each individual’s home range, highlighting the importance of a continuous spatial distribution of suitable nest trees across the landscape. Nest trees were also located in adjacent farmland up to 225 m from roadside vegetation, demonstrating the value that scattered clumps and even single trees in farmland can have for wildlife conservation.

Factors affecting patch occupancy by the white-browed treecreeper Climacteris Affinis in an agricultural landscape in north-west Victoria, Australia

The survival of habitat-dependent fauna within agricultural mosaics depends on their ability to occupy remnant habitat patches and move through the modified landscape. In north-west Victoria, Australia, less than 10% of the pre-European extent of Selah Casuarina pauper woodland remains intact due to agricultural development. The White-browed Treecreeper Climacteris affinis, is a small, insectivorous passerine that, in this region, preferentially inhabits Selah woodland. To assess the ability of C. affinis to persist in an agricultural landscape, 30 woodland sites in the Millewa landscape (34°30'S, 141°30'E) were surveyed, and patterns of patch occupancy used to examine the influence of spatial characteristics, landscape context and grazing by stock on the suitability of remnants as C. affinis habitat. Sites occupied by C. affinis were larger and less likely to be grazed by stock than vacant patches. The area-dependency of patch occupancy represents a step-threshold: C. affinis were not detected in remnants with less than 18.5 ha of Selah woodland but above this threshold, density was not correlated with patch area. Measures of patch isolation, the existence of linking linear "corridors" and tree density were not reliable indicators of patch occupancy. The presence of the species in remnants entirely surrounded by agricultural land suggests they are capable of crossing up to 450 m of cultivated land to prospect for habitat. The extensive network of linear vegetation and the numerous small remnants and scattered trees appear to facilitate movements of C. affinis in this landscape. Increasing the size of existing remnants, creating new habitat to expand the area of occupancy and maintaining landscape connectivity are priorities for the long-term management of this threatened species.

The clinical landscape of critical care: nurses' decision-making

Background. Many studies have tended to explore individual characteristics that impact on nurses' decision-making, despite significant acknowledgement that context is a major determinant in decision-making. The few studies that have examined environmental influences have tended not to study real decisions in the dynamic and complex clinical environment.

Aims. To investigate environmental influences on nurses' real decisions in the critical care setting.

Method. Naturalistic observations and semi-structured interviews were conducted with 18 critical care nurses in private, public and rural hospitals. Observations and interviews were recorded, transcribed verbatim and coded for themes using content analysis.

Results. All clinical decisions were strongly influenced by the context in which the decision was made. Three main environmental influences were identified: the patient situation, resource availability and interpersonal relationships. Time and risk guided all clinical decisions. Nurses established the state of the situation, the time constraints on decisions and the level of risk involved for both patient and nurse.

Conclusions. Decision-making is a manifestation of the landscape and although an increased understanding of the landscape is required, more important is the need to measure the impact of contextual variables on nurses' decision-making in order to improve health care outcomes.
