Multiple threats, or multiplying the threats? Interactions between invasive predators and other ecological disturbances

Invasive species have reshaped the composition of biomes across the globe, and considerable cost is now associated with minimising their ecological, social and economic impacts. Mammalian predators are among the most damaging invaders, having caused numerous species extinctions. Here, we review evidence of interactions between invasive predators and six key threats that together have strong potential to influence both the impacts of the predators, and their management. We show that impacts of invasive predators can be classified as either functional or numerical, and that they interact with other threats through both habitat- and community-mediated pathways. Ecosystem context and invasive predator identity are central in shaping variability in these relationships and their outcomes. Greater recognition of the ecological complexities between major processes that threaten biodiversity, including changing spatial and temporal relationships among species, is required to both advance ecological theory and improve conservation actions and outcomes. We discuss how novel approaches to conservation management can be used to address interactions between threatening processes and ameliorate invasive predator impacts.

Relationships between inflammatory cytokine and cortisol responses in firefighters exposed to simulated wildfire suppression work and sleep restriction

The interplay between inflammatory and cortisol responses modulates an appropriate response to a stressor. Exposure to severe stressors, however, may alter the actions and relationships of these responses and contribute to negative health outcomes. Physical work and sleep restriction are two stressors faced by wildland firefighters, yet their influence on the relationship between inflammatory and cortisol responses is unknown. The aim of the present study was to quantify the relationship between the cytokine and cortisol responses to sleep restriction while performing simulated physical wildfire suppression work. Firefighters completed 3 days of simulated physical firefighting work separated by either an 8-h (Control condition; n = 18) or 4-h sleep (Sleep restriction condition; n = 17) opportunity on each of the two nights. Salivary cortisol and inflammatory cytokines (IL-6, IL-8, IL-1β, TNF-α, IL-4, and IL-10) were measured throughout each day. An increase in morning IL-6 was related to a rise (6.2%, P = 0.043) in evening cortisol among firefighters in the sleep restriction condition. Higher morning IL-6 levels were related to increased (5.3%, P = 0.048) daily cortisol levels, but this relationship was not different between conditions. Less pronounced relationships were demonstrated between TNF-α, IL-10, IL-4, and cortisol independent of the sleep opportunity, but relationships did not persist after adjusting for demographic factors and other cytokines. These findings quantify the relationship between cytokine and cortisol responses among wildland firefighters exposed to simulated occupational stressors. Potential disturbances to the IL-6 and cortisol relationship among sleep-restricted firefighters' supports further investigations into the negative health effects related to possible imbalances between these systems.

Cross-cultural encounters and 'difficult heritage' on the Thai-Burma railway: an ethics of cosmopolitanism rather than practices of exclusion

This chapter argues for the significance of embodied actions and their traces in the heritage landscape as traces of cross-cultural practices in the context of interpreting difficult heritage in places where the heritage of war is of significance for multiple stakeholders.

The role of dietary choices and medical expenditures on health outcomes when health shocks are endogenous

This paper presents a theoretical framework that incorporates both a role for preventive actions (through food choices) and treatment (through medical services) to improve health outcomes. In particular, we allow for an agent's calorie decision to alter the distribution of future health shocks. Once a shock is realized, medical care can be used to improve health outcomes. Thus this model can help us determine the role of the preventive actions and treatments in producing better health outcomes and study the links between an agent's choice of medical services and her diet. This framework suggests that wealthier individuals, on average, have lower morbidity rates and lead a healthier lifestyle than lower income agents. Finally, our numerical exercise captures U.S. cross-sectional facts regarding the choice of diet, medical expenditures as well as health and non-food expenditures.

Remuneration committee effectiveness and narrative remuneration disclosure

This paper investigates the impact of the effectiveness of remuneration committees on narrative voluntary disclosure of information on remuneration. We develop a composite measure as a proxy for remuneration committee effectiveness by incorporating remuneration committee size, remuneration committee independence, remuneration committee chairman’s independence, expertise and diligence. We find that both the existence and quality of a remuneration committee play a significant role in the decision to provide voluntary disclosure of remuneration actions and in the extent of this disclosure. Further analysis suggests that remuneration committee independence and diligence enhance the quality of remuneration committees. The results have policy implications for remuneration committees as an effective corporate governance mechanism.

The why, what, and how of global biodiversity indicators beyond the 2010 target

The 2010 biodiversity target agreed by signatories to the Convention on Biological Diversity directed the attention of conservation professionals toward the development of indicators with which to measure changes in biological diversity at the global scale. We considered why global biodiversity indicators are needed, what characteristics successful global indicators have, and how existing indicators perform. Because monitoring could absorb a large proportion of funds available for conservation, we believe indicators should be linked explicitly to monitoring objectives and decisions about which monitoring schemes deserve funding should be informed by predictions of the value of such schemes to decision making. We suggest that raising awareness among the public and policy makers, auditing management actions, and informing policy choices are the most important global monitoring objectives. Using four well-developed indicators of biological diversity (extent of forests, coverage of protected areas, Living Planet Index, Red List Index) as examples, we analyzed the characteristics needed for indicators to meet these objectives. We recommend that conservation professionals improve on existing indicators by eliminating spatial biases in data availability, fill gaps in information about ecosystems other than forests, and improve understanding of the way indicators respond to policy changes. Monitoring is not an end in itself, and we believe it is vital that the ultimate objectives of global monitoring of biological diversity inform development of new indicators.

Monitoring and accountability for the Pacific response to the non-communicable diseases crisis

BACKGROUND: Non-communicable diseases (NCD) are the leading cause of premature death and disability in the Pacific. In 2011, Pacific Forum Leaders declared "a human, social and economic crisis" due to the significant and growing burden of NCDs in the region. In 2013, Pacific Health Ministers' commitment to 'whole of government' strategy prompted calls for the development of a robust, sustainable, collaborative NCD monitoring and accountability system to track, review and propose remedial action to ensure progress towards the NCD goals and targets. The purpose of this paper is to describe a regional, collaborative framework for coordination, innovation and application of NCD monitoring activities at scale, and to show how they can strengthen accountability for action on NCDs in the Pacific. A key component is the Dashboard for NCD Action which aims to strengthen mutual accountability by demonstrating national and regional progress towards agreed NCD policies and actions.

DISCUSSION: The framework for the Pacific Monitoring Alliance for NCD Action (MANA) draws together core country-level components of NCD monitoring data (mortality, morbidity, risk factors, health system responses, environments, and policies) and identifies key cross-cutting issues for strengthening national and regional monitoring systems. These include: capacity building; a regional knowledge exchange hub; innovations (monitoring childhood obesity and food environments); and a robust regional accountability system. The MANA framework is governed by the Heads of Health and operationalised by a multi-agency technical Coordination Team. Alliance membership is voluntary and non-conditional, and aims to support the 22 Pacific Island countries and territories to improve the quality of NCD monitoring data across the region. In establishing a common vision for NCD monitoring, the framework combines data collected under the WHO Global Framework for NCDs with a set of action-orientated indicators captured in a NCD Dashboard for Action.

SUMMARY : Viewing NCD monitoring as a multi-component system and providing a robust, transparent mutual accountability mechanism helps align agendas, roles and responsibilities of countries and support organisations. The dashboard provides a succinct communication tool for reporting progress on implementation of agreed policies and actions and its flexible methodology can be easily expanded, or adapted for other regions.

Using Butler to understand the multiplicity and variability of policy reception

Understanding how teachers make sense of education policy is important. We argue that an exploration of teacher reactions to policy requires an engagement with theory focused on the formation of ‘the subject’ since this form of theorisation addresses the creation of a seemingly coherent identity and attitude while acknowledging variation across different places and people. In this paper, we propose the utility of Butlerian ideas because of the focus on subjectivity that her work entails and the account she gives for social norms regulating people’s actions and attitudes. We use Butler’s stance on how ‘cultural intelligibility’ is formed to account for the complex, messy and sometimes contradictory ‘take up’ of curriculum policy by 10 teachers at a secondary school case study in Queensland, Australia. We use the phrase ‘policy reception’ to signify a particular theoretical line of thought we are forming with our application of Butlerian theory to the analysis of teacher attitudes toward curriculum policy, and to distinguish it from ‘policy interpretation’, ‘policy translation’ and ‘policy enactment’.

Regimes of risk: the need for a pedagogy for peer groups

Peer groups matter more than we think. In this paper we assert that peer group commitments and affiliations are often the primary social reference in determining the way young people think about and practice risk. It is, we argue, inappropriate to impose adult constructions of risk-taking and anti-social behaviour when trying to assert influence over the decisions and practices young people make in the context of their peers. Prominent in our discussion is a concern that mainstream educational theory and practice focuses disproportionately on the individual and their capacity to make rational and independent choices. We believe that within this individualizing framework, teachers have only a very limited capacity to influence the practices and decisions young people make in the presence of their peers, their friends. To ground this discussion we juxtapose the actions and interactions of two young male peer groups, to highlight their respective constructions of group identity.

Does a continence educational brochure promote health-seeking behavior?

OBJECTIVE: This study reviewed whether participants who were given a continence education package, which included a Continence Educational Brochure (CEB), and who indicated that they were bothered by incontinence symptoms changed health-seeking behaviors about their incontinence problem because of being given the brochure.
METHOD: This study used a descriptive and exploratory design. Participants were given the CEB and asked to read the information. They were also asked to complete a continence questionnaire and mail this back to the research team. Participants who indicated that they were bothered by a continence problem and consented to being interviewed were telephoned 2 to 3 months later. They were asked questions to determine their actions and progress in relation to managing their continence problem and whether the CEB had influenced their behavior.
SETTING AND SUBJECT: A total of 631 participants (352 females, 55.8%; 279 males, 44.2%) from 4 rural and regional settings in Victoria, Australia, participated. Of this sample, 111 participants (78 females, 70.3%; 33 males, 29.7%) who reported that they were bothered by a continence problem were interviewed 3 months after being given the CEB.
RESULTS: Two thirds of the total sample of participants (n = 111) sought help for their continence problem. Approximately 70.3% (n = 78) continued to have a continence problem. Of this group, 84.6% were still bothered by the continence problem and 65.4% had taken action to treat their incontinence. Forty-nine participants (44.1%) indicated that they had discussed the issue of bladder or bowel problems with someone directly because of this study or the information contained in the brochure. More than 94% of participants who remembered the CEB indicated that they believed the brochure would be helpful if given to other people.
CONCLUSIONS: These findings suggest that the CEB prompted individuals to discuss their continence problem and in fewer cases to seek professional help. Given these findings, distribution of a continence education package is advocated as a continence health promotion strategy.

Foraging ecology of ground-feeding woodland birds in temperate woodlands of Southern Australia

Ground-foraging birds of temperate woodlands of southern Australia are prominent among bird species considered to be susceptible to population decline. We examined the foraging ecology, including foraging substrates, actions and heights, of 13 ground-foraging species at four woodland sites in northern Victoria. Nine species are regarded as declining in southern Australia and four are considered common. Ten foraging substrates were identified, of which leaf-litter (54% of observations) and bare ground (17%) were most frequently used. In all woodland sites, litter was used more frequently than expected from its proportional cover. Bare ground was frequently used as a substrate by individual species, and fallen timber and grass were important for some species. Most species were generalists in their use of substrates. Six foraging actions were observed, of which gleaning and pouncing were most frequently recorded. All species foraged close to the ground and four foraged almost entirely at ground level. For pouncing birds, dead branches and fallen timber were the most important launch substrates from which pouncing actions were initiated. Eight of the 13 species differed in some aspect of their foraging ecology between woodland sites, especially in relation to the use of substrates (seven species). Fewer species (four) displayed differences in foraging ecology between seasons, with the greatest seasonal variation being in use of foraging substrates (three species). Overall, no significant differences were evident in the foraging ecologies of common and declining species. Species in both groups encompassed a wide range of foraging behaviours. Owing to this range in foraging ecology, the conservation of diverse assemblages of ground-foraging birds requires the maintenance of heterogeneous ground layers and careful management of disturbance processes.

Painting equality : female artists as cultural entrepreneurial marketers

Purpose – There is growing interest by marketers in historical accounts that paint early female artists as entrepreneurial marketers. The purpose of this paper is to challenge the traditional view of entrepreneurship to incorporate a feminist theory of cultural entrepreneurship by considering the role of two female artists.
Design/methodology/approach – Using calls for historical research and new methods of enquiry in marketing, this paper traces early female artists and applies modern entrepreneurial theory to their marketing methods to identify their innovation, adaptability to change and planned marketing approach.
Findings – The paper suggests that entrepreneurial marketing is fused with the artists’ persona resulting in their celebrated status being widely recognised. It contributes an important fresh body of knowledge to the wider entrepreneurship debate by offering a new model of cultural entrepreneurial marketing. The three concepts of innovation, adaptability and marketing approach have not previously been applied to link women artists as entrepreneurs, however, this article argues that there is plenty of evidence to do so.
Research limitations/implications – While these artists are Australian (which could be seen to be a limitation), the art market is indeed international. In this respect, these artists join a longer international history as producers and consumers involved in entrepreneurial organisations from early days.
Originality/value – The artists’ significance falls within the context of emerging modernism, feminism and cultural identity during the 1920s and 1930s in Sydney, Australia. It is combined with and explains the actions and the success of two female artists’ unusual marketing approach. It is of value to readers interested in historical context regarding equality in the visual arts.

Understanding public involvement with Australian heritage : a qualitative study using repertory grid analysis

Attempts to increase public participation in heritage related activities have had mixed success. Tourism to heritage sites remains an overt activity that many engage in, but other heritage related activities, such as nominating objects for formal heritage listing, are much rarer. Through a series of qualitative research activities, we examine the public perceptions of what constitutes "heritage" and "heritage - related" behaviours, in order to examine barriers to greater involvement. The findings are that heritage is important to many people, particularly on a personal level. Although initially uncertain about the validity of their views, our respondents defined heritage broadly, believing it to encompass a wide range of objects, places and experiences. Most respondents were undertaking the type of heritage-related behaviours that heritage managers would encourage, however the respondents did not recognise them as being heritage-related. Barriers to greater involvement include this uncertainty over the definition of heritage and a lack of confidence in their ability to effectively recognise and protect heritage. In addition to feeling uncertain about the heritage significance of their own actions and beliefs, the respondents felt even more uncertain about prescribing things of "national heritage value". This uncertainty stifles discussion and action. The solution appears to lay in celebrations of both individual and national heritage, to foster discussions and understanding of communalities across different cultural groups within the nation.

Rugby league: a game in crisis

This study examines the issue of crisis and reputation management strategies in Australian sporting clubs and finds that not only are individual clubs unaware of the potential impact of such crises on their organizations, but that they also have no training, contingency plans, or strategies to handle crises of any sort either at this or at the national league level. It uses the Australian Rugby League organization as a case study f()r examining these issues and concludes with several recommendations for improving crisis management and communications policies in Australian sporting organizations and for their stakeholders.

Many public and private organizations prefer to ignore the reality that "bad things" can happen, either through denial of their vulnerabilities or through myopia about their successes and strengths (Elliott, 2002). A crisis can be defined as any problem or disruption that triggers negative stakeholder reaction and extensive public scrutiny (Newman, 2003). Effective crisis management lies in continuous learning processes designed to equip managers with the capabilities, flexibility, and confidence to deal with sudden and unexpected problems or events (Robert & Lajtha, 2002). Good crisis leaders are those who can make fast decisions under pressure and who can keep the big picture consequences of actions and words in mind when making these decisions 030in & Lagadec, 20(0). In 2004, the Rugby league in Australia was both ill-prepared and ill-advised to effectively deal with a sex scandal involving a number of their players on an official club tour. In classic crisis escalation, what should have been a serious but easily dealt with problem became a major reputational and institutional crisis for the league, its sponsors, its players, and its fans.
