The paper criticises the dominant discourse of corporate social responsibility (CSR) by examining six sets of factors conventionally considered as promoting outcomes consistent with core principles of social responsibility: intra-organizational factors, competitive dynamics, institutional investors, end-consumers, government regulators and non-governmental organizations. Each factor is addressed conceptually, empirically, and with respect to its likely future significance in promoting outcomes consistent with CSR. Our overall conclusions are not promising on any of these dimensions.

The diversity of countries and cultures in Europe necessitates an international outlook for most businesses. This paper examines the internationalisation of business in Europe through a literature review on international entrepreneurship theory. The role of the individual business owner and of business and interorganisational activity in facilitating the internationalisation of businesses in Europe is discussed by utilising the theoretical framework of international entrepreneurship and by putting forward three main propositions. The main aim and intent of this paper is to understand how the policies of individual governments and institutions such as the European Union help businesses in Europe to internationalise, with particular emphasis on businesses in the Baltic region. The paper discusses policy implications and suggestions for future research, which highlight the importance for firms in Europe of focussing on international markets.

The drive to undertake building adaptation has increased in momentum, the primary reason being adaptation can be less expensive than new build and conventionally result in faster project delivery times. The issue of sustainable development is another clear driver for adaptation and collectively buildings contribute around half of all greenhouse gas emissions. At the same time governments seek effective and efficient ways of reducing the contribution of cities to climate change and building adaptation appears to offer a practical means of reducing building-related emissions. One example is the ‘1200 building program’ which aims to increase adaptation rates with a target of 1200 city centre office adaptations by 2020 as part of the strategy to achieve carbon neutrality. Through a longitudinal examination of building adaptations it is possible to identify the nature and extent of typical levels of adaptation, as well as determining the inter-relationship between different types of adaptation and building attributes. Melbourne city centre was used for a case study which analysed 5290 building adaptation events between 1998 and 2008. The findings promote the adaptive reuse of buildings in specific circumstances and are directly applicable for increasing sustainability in the built environment. The case study focused on existing buildings in a global city to ensure relevance to urban centres where existing commercial buildings can become part of the solution to mitigate climate change.

The simultaneous increases in obesity in almost all countries seem to be driven mainly by changes in the global food system, which is producing more processed, affordable, and effectively marketed food than ever before. This passive overconsumption of energy leading to obesity is a predictable outcome of market economies predicated on consumption-based growth. The global food system drivers interact with local environmental factors to create a wide variation in obesity prevalence between populations. Within populations, the interactions between environmental and individual factors, including genetic makeup, explain variability in body size between individuals. However, even with this individual variation, the epidemic has predictable patterns in subpopulations. In low-income countries, obesity mostly affects middle-aged adults (especially women) from wealthy, urban environments; whereas in high-income countries it affects both sexes and all ages, but is disproportionately greater in disadvantaged groups. Unlike other major causes of preventable death and disability, such as tobacco use, injuries, and infectious diseases, there are no exemplar populations in which the obesity epidemic has been reversed by public health measures. This absence increases the urgency for evidence-creating policy action, with a priority on reduction of the supply-side drivers.

Climatic conditions in Australia are erratic and characterised by periods of intense rainfall followed by periods of intense drought. This has considerable impact on the population dynamics and ecology of many Australian species of waterfowl, which are thought to form the reservoir of avian influenza viruses (AIV) but may also be important carriers (and possibly reservoirs) of other diseases (e.g. bursal disease, Newcastle disease). During the wet, waterfowl numbers increase with many serologically naive juveniles entering the population. During the subsequent period of drought, bird densities increase in the few remaining wetlands. We hypothesise that it is during this period of increasing densities of naive birds that the population’s viral prevalence of some infectious diseases may increase dramatically. Indeed, there exists a remarkable and suggestive coincidence between outbreaks of fowl plaque and Newcastle disease in Australian poultry farms and the periods of drought following a very wet period. In other words, we suspect a link between increased risk for disease outbreaks in poultry farms and the hypothesised high in the prevalences of the viruses causing these diseases in waterfowl. Given that poultry farms may provide ideal conditions for development of high-pathogenic strains, there is also a reciprocal risk for wildlife involved during these periods.

Purpose - While the body of work exploring brand orientation has grown, there has been a general failure to build on extant research and generate a holistic conceptualization of brand orientation. This paper aims to develop a model of the key drivers, impediments and manifestations of brand orientation in a museum context.

Design/methodology/approach - A collective case study design was used, consisting of key informant interviews using a semi-structured interview protocol and analysis of institutional documents and observational research. Interviews took place with well-known museums across three countries: the United Kingdom, the United States of America and Australia. This paper demonstrates the richness of qualitative case studies as a method of theory building and as a precursor to further empirical research.

Findings - The case study findings reveal both a philosophical and behavioral aspect of brand orientation. Thus, six attributes are presented that include brand orientation as an organizational culture and compass for decision-making and four brand behaviors (distinctiveness, functionality, augmentation and symbolism). The conceptual model also depicts the critical antecedents to brand orientation in a museum context.

Research limitations/implications - This study provides a foundation for future brand research by offering a holistic conceptualization of brand orientation and identifying the primary antecedents in a museum context. Future research may wish to empirically establish a valid and reliable scale of brand orientation and examine its explanatory potential. Future research may also consider other contexts to provide further insight into the drivers and inhibitors of brand orientation.

Practical implications - If organizations seek to establish a strong brand orientation they must devote resources to establishing the brand as a dominant organizational philosophy that guides decision-making. In addition, brand oriented organizations must establish the brand as a distinctive asset that communicates relevance and accessibility and invest in augmenting initiatives that enable the organization to connect with customers on a personal and emotional level.

Originality/value - Using an exploratory method we are able to reconcile a number of approaches to brand orientation and provide a conceptualization that incorporates the philosophical and behavioral approaches to business orientations. Museums face substantial resource constraints, competing needs of multiple stakeholders and increasing market turbulence. If museums can achieve such significant organizational change then the sector presents an interesting exemplar for many other non-profit organizations.

Despite frequent reliance on surveys to document public attitudes towards conservation issues (such as invasive-species control), only rarely do researchers assess the validity of statements made by the public in response to such surveys. Therefore, how well responses match actual behaviour remains an open question. We conducted a survey asking drivers if they had seen and/or run over (intentionally or not) snakes, native frogs or invasive cane toads (Rhinella marina) on roads in the Northern Territory of Australia. To compare actual driver behaviour to the survey responses, we also carried out field experiments where we quantified the rates at which model snakes, frogs and toads (and controls) were run over on a rural highway. Our results show a discrepancy between survey responses and driver behaviour: for example, 25% of the people we surveyed indicated that they intentionally run over cane toads, yet field experiments showed that model toads were run over no more frequently than expected by chance, or than any other type of model.

Over the last decade various waterfront cities have undergone major redevelopments, for example Wellington, Southbank (Melbourne), Baltimore, Sydney and Canary Wharf (London). These were all completed prior to the global financial climate of 2008/10. The world has changed. This paper explores the drivers for past port city redevelopment projects; What impetus drove these projects forward? What tools supported the projects to go ahead? In an unstable financial market do these remain viable? And if not are there new drivers which are stepping in to replace the classic drivers of the past? A literature review of academic, practitioner, policy documents and social media is analyzed to establish the drivers of the past, comparing these to current and future drivers. The review will be based on a survey of 40 international cities based on or near a port which have undergone significant redevelopment prior to or during the 2008/10 financial crisis. It assesses the drivers for sustainable development in port cities and explores the potential for establishing a matrix for successful sustainable development.

Purpose – The purpose of this paper is to use Australian Real Estate Investment Trust (A-REIT) data to empirically examine potential influencing factors on A-REITs becoming a bidder or a target in the mergers and acquisitions (M&A) area.

Design/methodology/approach – This study uses logistic regression analysis to investigate the odds of publically traded A-REITs being either a bidder or a target as a function of a number of financial and corporate governance variables.

Findings – Prior research in the US REIT M&A area has shown that target size is inversely related to takeover likelihood; in contrast, the authors’ Australian results show that size has a positive impact. Prior research on share price and asset performance has shown that underperformance increases the odds of an entity becoming a target, but this paper’s results further support these findings and provide confirmation of the inefficient management hypothesis. For acquirers it was found that leverage, cash balances, management structure, the level of shares held by related parties and the global financial crisis have an important impact on bidder likelihood.

Practical implications – Given that the literature suggests that investors can earn significant positive abnormal returns by owning targets, but incur significant abnormal losses by owning bidders, at announcement, this study will be useful to fund managers and other investors in A-REITs by investigating the characteristics of those firms that become targets and bidders.

Originality/value – This paper adds to the recent US REIT M&A literature by examining the second biggest REIT market in the world and reporting a number of factors that might influence A-REITs to become targets or bidders.

A key task in ecology is to understand the drivers of animal distributions. In arid and semi-arid environments, this is challenging because animal populations show considerable spatial and temporal variation. An effective approach in such systems is to examine both broad-scale and long-term data. We used this approach to investigate the distribution of small mammal species in semi-arid ‘mallee’ vegetation in south-eastern Australia. First, we examined broad-scale data collected at 280 sites across the Murray Mallee region. We used generalized additive mixed models (GAMMs) to examine four hypotheses concerning factors that influence the distribution of individual mammal species at this scale: vegetation structure, floristic diversity, topography and recent rainfall. Second, we used long-term data from a single conservation reserve (surveyed from 1997 to 2012) to examine small mammal responses to rainfall over a period spanning a broad range of climatic conditions, including record high rainfall in 2011. Small mammal distributions were strongly associated with vegetation structure and rainfall patterns, but the relative importance of these drivers was species-specific. The distribution of the mallee ningaui Ningaui yvonneae, for example, was largely determined by the cover of hummock grass; whereas the occurrence of the western pygmy possum Cercartetus concinnus was most strongly associated with above-average rainfall. Further, the combination of both broad-scale and long-term data provided valuable insights. Bolam's mouse Pseudomys bolami was uncommon during the broad-scale survey, but long-term surveys showed that it responds positively to above-average rainfall. Conceptual models developed for small mammals in temperate and central arid Australia, respectively, were not, on their own, adequate to account for the distributional patterns of species in this semi-arid ecosystem. Species-specific variation in the relative importance of different drivers was more effectively explained by qualitative differences in life-history attributes among species.
