Young People and Public Space: Developing Inclusive Policy and Practice

Issues about young people’s use of public and community spaces are now commonly raised in many countries. As urban space becomes more intensely used and the patterns of use of various types of space changes so a range of tensions have emerged for a range of parties including local government, shopping centre management, youth services and young people themselves.

An examination of the pastoral needs of students and the needs of their teachers as providers of pastoral care

The problem addressed by this research project is expressed in two parts. Firstly an examination of the pastoral care needs of students at a particular independent secondary school. Secondly, an examination of the needs of the teachers (as providers of pastoral care) who are attempting to understand and deal with the pastoral needs of the students. The research takes the form of a bounded case study, employing techniques of data gathering and analysis from each of the positivistic and naturalistic paradigms. As such then the study is described as mixed - mode research allowing for the triangulation (Jick, 1979. p.602) of both qualitative and quantitative data. Data were gathered from students by means of an attitude survey and through the use of personal interviews. Information was collected from teachers by means of two rounds of interviews and through a whole-staff seminar. Methods of analysis of these data were appropriate to the types of data involved. The quantitative data were analysed via the application of a computer-based data analysis programme and the qualitative data were analysed through emergent categorisations. The findings from each set of data were then examined side by side to provide a broad understanding of the case. The findings of the research, provided useful information about the attitudes of the students to a wide range of aspects of school-life, and highlighted general and specific areas of pastoral care related need. Similarly, for the teachers, attitudes, needs and indications of strengths and weaknesses of the school\u27s pastoral care provisions became apparent. Significant amongst the specific needs of teachers was the need for increased and improved training in pastoral care skills at both the pre-service and in-service levels

Reactive system verification case study: Fault-tolerant transputer communication

A reactive program is one which engages in an ongoing interaction with its environment. A system which is controlled by an embedded reactive program is called a reactive system. Examples of reactive systems are aircraft flight management systems, bank automatic teller machine (ATM) networks, airline reservation systems, and computer operating systems. Reactive systems are often naturally modeled (for logical design purposes) as a composition of autonomous processes which progress concurrently and which communicate to share information and/or to coordinate activities. Formal (i.e., mathematical) frameworks for system verification are tools used to increase the users' confidence that a system design satisfies its specification. A framework for reactive system verification includes formal languages for system modeling and for behavior specification and decision procedures and/or proof-systems for verifying that the system model satisfies the system specifications. Using the Ostroff framework for reactive system verification, an approach to achieving fault-tolerant communication between transputers was shown to be effective. The key components of the design, the decoupler processes, may be viewed as discrete-event-controllers introduced to constrain system behavior such that system specifications are satisfied. The Ostroff framework was also effective. The expressiveness of the modeling language permitted construction of a faithful model of the transputer network. The relevant specifications were readily expressed in the specification language. The set of decision procedures provided was adequate to verify the specifications of interest. The need for improved support for system behavior visualization is emphasized

An NMR Study of Helium-3 Adsorbed on Hexagonal Boron Nitride

A Pulse-NMR study of helium-3 adsorbed on hexagonal boron-nitride (BN) powder has been performed. Structurally very similar to graphite, the exposed basalplanes present a very smooth, ideal adsorbing surface and lack its undesirable strong anisotropic diamagnetism. The relaxation times T1 and T2 of helium-3 have been measured as a function of coverage, temperature and frequency. A variety of two dimensional phases have been observed including: a fluid, commensurate solid, incommensurate solid plus a separate crystallite edge film. 2D melting in the incommensurate solid and an order-disorder transition in the commensurate solid have been observed. Evidence for a low temperature, low coverage fluid+commensurate solid coexistence which transforms to a single phase at higher temperatures plus a possible domain-wall phase at higher coverages has been identified. Coupled magnetic relaxation between the helium-3 film and substrate boron-11 spins has been noted. Boron-11 relaxation times have been measured against coverage and temperature. Heteronuclear relaxation is particularly important in the commensurate phases where it can dominate homonuclear spin-lattice relaxation, providing a powerful new probe of the low coverage phases. Based on the detailed theory of coupled magnetic dipolar relaxation a model has been developed which quantitatively describes all the important features of the data many of which are unique to the BN/3He system. Presented separately in chapter 8, it concludes the magnetic properties of registered helium 3 spins are dominated by 14N�� 3He cross relaxation processes, mediated by the €14N quadrupole splitting at FQ(14N) and driven by exchange motion in the film. Using a computer for unattended, real-time experimental control has allowed substantial quantities of high quality relaxation data to be taken. Off-line, automated, numerical analysis of raw spin-echo and processed data has been extensively used. Modelling relaxation data with a stretched-exponential function, h(t) = h(0) exp(ta/T1,2) has provided a exceptionally sensitive indicator of physical changes in the film

Long-term bird colonization and turnover in restored woodlands

The long-term effectiveness of restored areas for biodiversity is poorly known for the majority of restored ecosystems worldwide. We quantified temporal changes in bird occurrence in restoration plantings of different ages and geometries, and compared observed patterns with a reference dataset from woodland remnants on the same farms as our plantings. Over time, bird species richness remained unchanged in spring but exhibited modest increases in winter. We found that wider plantings supported significantly greater bird species richness in spring and winter than narrow plantings. There was no evidence of a significant interaction between planting width and time. We recorded major temporal changes in the occurrence of a range of individual species that indicated a clear turnover of species as plantings matured. Our results further revealed marked differences in individual species occurrence between plantings and woodland remnants. Life-history attributes associated with temporal changes in the bird assemblage were most apparent in winter survey data, and included diet, foraging and nesting patterns, movement behaviour (e.g. migratory vs. dispersive), and body size. Differences in bird assemblages between plantings of different ages suggest that it is important that farms support a range of age classes of planted woodland, if the aim is to maximize the number of native bird species in restored areas. Our data also suggest that changes in the bird species occupying plantings of different ages can be anticipated in a broadly predictable way based on planting geometry (especially width) and key life-history attributes, particularly movement patterns and habitat and diet specialisation. © 2016, Springer Science+Business Media Dordrecht. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Philip Barton” is provided in this record*

Cross-taxonomic surrogates for biodiversity conservation in human-modified landscapes – A multi-taxa approach

Cross-taxonomic surrogates are often used in conservation planning because inventorying large suites of taxa is either not feasible or too costly. However, cross-taxonomic surrogates are seldom tested rigorously using both correlational and representation-based approaches at the spatial scales at which conservation management occurs. Here, we evaluated the effectiveness of five ecologically contrasting taxa (birds, herpetofauna, wild bees, beetles, trees) as cross-taxonomic surrogates in native woodland patches within a heavily modified, farming and plantation-dominated landscape. We first compared species richness and compositional heterogeneity across taxa before testing for cross-taxonomic congruence using a correlative approach. We then quantified how well each taxon incidentally represented other taxa in their best patch sets, and the costs of doing so using a complementarity-based approach. We found significant pairwise associations between some taxa (birds, bees), but no single taxon was strongly correlated with all other taxa. Woodland patch sets prioritised for beetles represented other taxa best, followed by birds, but were the costliest and required the largest amount of woodland. This contrasted with patch sets prioritised for wild bees or herpetofauna, which achieved higher representation of other taxa at lower costs. Our study highlighted the influence of taxon-specific patterns of diversity and heterogeneity on how remnant vegetation patches should be prioritised for conservation, a consideration not immediately obvious in correlative analyses of surrogacy. Second, taxa that are not the most speciose (e.g. wild bees) can be efficient surrogates, achieving higher incidental representation for other taxa at lower costs. Thus, while species-rich taxa are ideal as surrogates for prioritising conservation, conservation planners should not overlook the potential of less speciose taxa such as bees, while considering the cost-effectiveness of surveying multiple different taxa. © 2018. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Philip Barton" is provided in this record*

Avian functional responses to landscape recovery

Restoring native vegetation in agricultural landscapes can reverse biodiversity declines via species gains. Depending on whether the traits of colonizers are complementary or redundant to the assemblage, species gains can increase the efficiency or stability of ecological functions, yet detecting these processes is not straightforward.We propose a new conceptual model to identify potential changes to complementarity and redundancy in response to landscape change via relative changes in taxonomic and functional richness.We applied our model to a 14-year study of birds across an extensive agricultural region. We found compelling evidence that high levels of landscape-scale tree cover and patch-scale restoration were significant determinants of functional change in the overall bird assemblage. This was true for every one of the six traits investigated individually, indicating increased trait-specific functional complementarity and redundancy in the assemblage. Applying our conceptual model to species diversity data provided new insights into how the return of vertebrates to restored landscapes may affect ecological function. © 2019 The Author(s)

Outdoor Worker Sun Protection Project : a mixed methods intervention to improve sun safety among outdoor workers

Queensland, Australia has one of the highest rates of skin cancer in the world. Outdoor workers are regularly exposed to high doses of ultraviolet radiation, and are at increased risk to develop non-melanoma and melanoma skin cancers. In 2010, a health promotion intervention to improve sun protection among outdoor workers in Queensland commenced. The intervention employed a mixed methods approach and a participatory action research framework. Fourteen workplaces were recruited from building and construction, rural and farming, local government, and public sector organisations. Management and workers were engaged in cycles of assessment, reflection and discussion, planning, implementation and reassessing, over a 14-month intervention period. Overall, at least one workplace representative from each workplace (range 1-3) and in depth focus groups were held with a subset of workers (range 3-16) to assess sun safe behaviours pre and post intervention. Workers’ attitudes, beliefs, knowledge and willingness to engage in sun protection differed depending on workplace characteristics and support. A familiar theme among workers spoke of sun safety as being “common sense” and the “workers individual responsibility”. Often there was a discrepancy in the perceptions of the workers, compared to the view of workplace representatives and the workplaces position or policy on sun safety. In larger workplaces, especially Government Departments, workers were more aware and followed sun safe practices compared to smaller workplaces where sun safety was not a high priority. These results indicate that a workplace culture which places high values on safety and polices more broadly may also have a positive effect on sun safety among outdoor workers as well. In addition, the specific characteristics of the workplace and the outdoor work tasks influence workers willingness to engage in sun safety measures

Cross-sectional and temporal relationships between bird occupancy and vegetation cover at multiple spatial scales

Scale is a key concept in ecology, but the statistically based quantification of scale effects has often proved difficult. This is exemplified by the challenges of quantifying relationships between biodiversity and vegetation cover at different spatial scales to guide restoration and conservation efforts in agricultural environments. We used data from 2002 to 2010 on 184 sites (viz., site scale) nested within 46 farms (the farm scale), nested within 23 landscapes (the landscape scale). We found cross-sectional relationships with the amount of vegetation cover that were typically positive for woodland birds and negative for open-country birds. However, for some species, relationships differed between spatial scales, suggesting differences in nesting and foraging requirements. There was a 3.5% increase in the amount of native vegetation cover in our study region between 2002 and 2010, and our analyses revealed that some open country species responded negatively to these temporal changes, typically at the farm and/or site scale, but not the landscape scale. Species generally exhibited stronger cross-sectional relationships with the amount of vegetation cover than relationships between changes in occupancy and temporal changes in vegetation cover. This unexpected result can be attributed to differences in habitat use by birds of existing vegetation cover (typically oldgrowth woodland) vs. plantings and natural regeneration, which are the main contributors to temporal increases in vegetation cover. By taking a multi-scaled empirical approach, we have identified species-specific, scale-dependent responses to vegetation cover. These findings are of considerable practical importance for understanding which species will respond to different scales of protection of existing areas of native vegetation, efforts to increase the amount of native vegetation over time, and both approaches together
