A succession of theories : purging redundancy from disturbance theory

The topics of succession and post-disturbance ecosystem recovery have a long and convoluted history. There is extensive redundancy within this body of theory, which has resulted in confusion, and the links among theories have not been adequately drawn. This review aims to distil the unique ideas from the array of theory related to ecosystem change in response to disturbance. This will help to reduce redundancy, and improve communication and understanding between researchers. We first outline the broad range of concepts that have developed over the past century to describe community change in response to disturbance. The body of work spans overlapping succession concepts presented by Clements in 1916, Egler in 1954, and Connell and Slatyer in 1977. Other theories describing community change include state and transition models, biological legacy theory, and the application of functional traits to predict responses to disturbance. Second, we identify areas of overlap of these theories, in addition to highlighting the conceptual and taxonomic limitations of each. In aligning each of these theories with one another, the limited scope and relative inflexibility of some theories becomes apparent, and redundancy becomes explicit. We identify a set of unique concepts to describe the range of mechanisms driving ecosystem responses to disturbance. We present a schematic model of our proposed synthesis which brings together the range of unique mechanisms that were identified in our review. The model describes five main mechanisms of transition away from a post-disturbance community: (i) pulse events with rapid state shifts; (ii) stochastic community drift; (iii) facilitation; (iv) competition; and (v) the influence of the initial composition of a post-disturbance community. In addition, stabilising processes such as biological legacies, inhibition or continuing disturbance may prevent a transition between community types. Integrating these six mechanisms with the functional trait approach is likely to improve the predictive capacity of disturbance theory. Finally, we complement our discussion of theory with a case study which emphasises that many post-disturbance theories apply simultaneously to the same ecosystem. Using the well-studied mountain ash (Eucalyptus regnans) forests of south-eastern Australia, we illustrate phenomena that align with six of the theories described in our model of rationalised disturbance theory. We encourage further work to improve our schematic model, increase coverage of disturbance-related theory, and to show how the model may link to, or integrate with, other domains of ecological theory.

The status quo of innovations within the construction industry: a conceptual model

The construction industry remains in need of applicable theories on the lifecycle of innovations. Nevertheless, construction researchers have hitherto used different constructs and various variables to present the status quo of an innovation. Building on an exhaustive literature review and analyses, this paper contributes to the body of knowledge on construction theories by presenting theoretical frameworks that represent the lifecycle of innovations and identifies the influential constructs and typologies. The study also discusses the view that constructs representing the cross-sectional state of an innovation within the construction industry should be universal in scope and meet the requirements of potential future studies and decision makers. The study concludes by developing a conceptual model illustrating the primary constructs and variables that could present the status quo of an innovation within the construction context.

Beyond the classroom: the community sector and school

The need for better education for improved personal benefit and quality of life is discussed. The research programs conducted by the Education Foundation identify the issues that and may help to improve conditions for students.

Beyond the classroom : building new school networks

Beyond the Classroom calls for new models of schooling that recognise that the future of young people is the responsibility of the whole community. These models should form the basis of a new social alliance across school systems enabling all young people to take an active—if not leading—role in that community, beyond the school gates.Beyond the Classroom is based on the findings of research carried out by the Education Foundation (now in alliance with the Foundation for Young Australians). The message that emerges from the research is that tinkering around the edges of schooling will not provide solutions to the widening gaps in education that limit opportunities for many young Australians.

Risk and benefit perceptions: Resistance, adoption and uses of ICT among the Italian elderly

This paper presents the main results of a national survey on active aging, with a sample of 900 Italians between 65 and 74 years of age. The research attempted to understand the role of ICT in the daily life of the elderly, in the attempt to answer the following questions: (1) What are the differences between the connected and not connected elderly? (2) What are the perceived risks and opportunities identified by older ICT users? This paper investigates the complex relationship between the elderly and technology, going beyond both deterministic approaches and optimistic analyses of the use (and non-use) of the Internet among elderly Italians.

Unsettling creativity: intercultural spaces, study abroad and internationlization beyond the curriculum

This chapter argues that short-term student Study Tours, coupled with preparatory and reflective classes on the home campus, are a more successful way of internationalizing the curriculum and promoting intercultural reflection than the more traditional, longer term student exchange. This is because taking students out of their comfort zones to travel overseas in a study intensive promotes greater ‘productive discomfort’ while supporting this process with classes on the home campus promotes its life changing effects.This chapter draws on two important Study Tours in Creative Writing and Creative and Commercial Entrepreneurship at Deakin University, Australia. The first is an outbound Study Tour to the United States and the second is an inbound Study Tour from India. These Study Tours foreground an important ‘unsettling’ of creativity that impacts on the students’ thinking and writing processes, and prepares them most effectively for their role as global citizens.

Beyond the market: alternate possibilities for valuing art

In our creative workshop we recreate the three 'types' of society by asking our audience to enact a society in which one particular mode of evaluation is dominant and subsequently enact another society based on another mode of evaluation. Participants will experience how different types of evaluation affect how we assemble ourselves as a society and ontologically. We make use of artworks that are representative of the three different eras as sensemaking devices of how societies have been ordered through different modes of evaluation.

Bonding beyond the pair in a monogamous bird: Impact on social structure in adult rooks (Corvus frugilegus)

The formation of social bonds outside the mated pair is not frequently reported in monogamous birds, although it may be expected in some species like rooks, living in groups all year round. Here we explore the social structure of captive adult rooks over three breeding seasons. We recorded proximities and affiliations (i.e., allofeeding, allopreening, contact-sit) to classify relationships according to their strength. Three categories of relationships emerged: primary (i.e., pairs), secondary and weak relationships. Affiliations and sexual behaviours were not restricted to pairs, and secondary relationships were clearly recognizable. Mixed-sex secondary relationships were qualitatively equivalent to pairs (i.e., same behaviours in the same proportions), although they were quantitatively less intense. Same sex pairs occurred, and were qualitatively equivalent to mixedsex pairs. Overall we found that rooks social structure is more than just an aggregation of pairs, which highlights the importance of considering extra-pair relationships in socially monogamous birds.
