Responses of Birds and Reptiles in Warrumbungle National Park after the Extensive 2013 Wildfire

In 2013 extensive wildfire burnt 90% (22104 ha) of Warrumbungle National Park in New South Wales, Australia. In 2014-2016 we assessed how species composition and abundance of birds and reptiles varied with fire severity and habitat characteristics. Of 91 bird species observed during surveys of 35 sites, 47 were more often on low severity sites. Bird species composition did not differ among vegetation communities although activity levels (species per 10 minutes) were reduced in woodland on sedimentary geology as compared with volcanic areas. With increasing fire severity bird activity and total number of species detected decreased, and species composition changed. Differences in species composition were due mainly to lower numbers of detections of small to medium-sized insectivores and nectarivores on high severity sites. Results were more complicated for the 36 species of reptiles observed during surveys than for birds. Reptile species composition varied with fire severity, geology, presence of rock outcrops and between vegetation communities. Species richness and abundance of many reptile groups, as well as the total number of individuals, decreased with increasing fire severity, but for reptiles overall and diurnal reptiles, presence of rock outcrops had a stronger effect on number of species and abundance. Differences between reptiles and birds and among reptile groups suggest that fire management for conservation needs to be at a range of scales and consider habitat attributes

An Assessment Framework for First-Year Introduction to Engineering Courses

In this evidence-based practice paper, we describe an assessment framework that applies to first-year introductory engineering courses. First-year engineering courses cover a variety of learning objectives that address both technical and professional outcomes outlined in ABET. These courses also often involve open-ended design and modeling projects. The assessment of multiple competencies along with open-ended design can be a challenging task for educators. In this paper, we describe a framework that guides instructional processes for effective assessment for student learning. This assessment-centered teaching and learning framework helps connect specific learning objectives to broader learning goals or competencies and on-going formative feedback targeting student progression on specific learning objectives. Our plan is to refine the framework using a design-based research approach. Following the description of the model and its development, we present results from the first cycle of implementation. We conclude by discussing hybrid ways for combining traditional methods of assessment with the ability to highlight performance expectations and the appropriate uses of the framework in the classroom

Using the Arts for Food Research and Dialogue

This Briefing Paper is intended to share ideas and learning arising from the authors’ experiences of using arts-based methods in food research and engagement, as well as to give some insights into the issues that arose from a workshop for academics and Civil Society Organisations (CSOs) developed by Brighton and Sussex Universities Food Network (BSUFN) and hosted by the Food Research Collaboration (FRC) in 2016. It examines the use of participatory and community-centred approaches to explore pressing food policy questions, as well as providing guidance on how to apply these methods in practice. It is intended to be relevant to academics, particularly those interested in using participatory action research methods, and CSOs working with community groups on food issues. The authors’ main interest is the way in which arts-based methods provide a set of tools which can reveal, and give voice to, perspectives on food issues which remain otherwise absent from research and policy debates. In the authors' experience, this happens either because community members are not asked for their views or because of the way in which much traditional/positivist/biomedical academic research is based around pre-determined research questions that do not provide adequate space for community members to explore and voice their own concerns. It could be said that to date, much food research has failed to meaningfully engage with the general public, both during the research process itself and in raising awareness and achieving changes in the food system, which the research evidence indicates needs to happen. The paper firstly outlines why food research is a necessary and important area of exploration. Following this it examines the development, lineage and underlying principles of participatory and arts-based methodologies as approaches to research. Three arts-based and participatory methods are then reviewed in greater detail: i. Photography and film ii. Drama, and iii. Collage. These three methods were the focus of the BSUFN/FRC workshop in 2016. For each of these three examples, theoretical and methodological implications and ethical issues are discussed, enabling readers to fully consider how and why they might apply these approaches. In reviewing these emerging and alternative approaches for engaging communities in research processes, this paper presents a consideration of ideas, narratives, positions and actions relating to food, research and knowledge construction. The authors believe this paper to be an important addition to debates around how arts based and participatory methods might improve the processes, impact and contribution of food research. The paper presents a collaborative effort between academics, researchers and civil society organisations (CSOs) all of whom are concerned with improving research, learning and engagement in relation to food. The paper concludes with recommendations and suggestions on how academics and CSOs might use these methods as part of their research and/or practice

A Nonparametric Method for the Derivation of α/β Ratios from the Effect of Fractionated Irradiations

Multifractionation isoeffect data are commonly analysed under the assumption that cell survival determines the observed tissue or tumour response, and that it follows a linear-quadratic dose dependence. The analysis is employed to derive the α/β ratios of the linear-quadratic dose dependence, and different methods have been developed for this purpose. A common method uses the so-called Fe plot. A more complex but also more rigorous method has been introduced by Lam et al. (1979). Their method, which is based on numerical optimization procedures, is generalized and somewhat simplified in the present study. Tumour-regrowth data are used to explain the nonparametric procedure which provides α/β ratios without the need to postulate analytical expressions for the relationship between cell survival and regrowth delay
