Agent-Based Modelling and Sensitivity Analysis by Experimental Design and Metamodelling: An Application to Modelling Regional Structural Change

This paper presents the application of the sensitivity analysis techniques Design of Experiments (DOE) and metamodelling to the agent-based model AgriPoliS, which is a spatial and dynamic simulation model of regional structural change. DOE and metamodelling provide a more systematic analysis of results of complex simulation models. When summarising the results, it becomes clear that interest rates, technical change and managerial ability influence average economic land rent the most.simulation, design of experiments, metamodelling, structural change, Research and Development/Tech Change/Emerging Technologies, C9, C15,

The gender dimensions of environmental change : an exploration of the experiences and perceptions of rural men and women in Zimbabwe : a thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Development Studies at Massey University, Manawatu, New Zealand

Processes of environmental change have taken place for centuries both as a result of natural variability and anthropogenic forces. As a concept however, environmental change continues to be used narrowly to refer to environmental changes which are biophysical in nature, and mostly those with global precedence. In recent times incidences of environmental change have become more complex as new patterns of change are threatening the livelihoods of those living in developing countries, undoing many development gains. As such, there is an increasing desire to understand the implications of environmental changes, particularly for those whose livelihoods are natural resource dependent, many of whom live in rural areas, and many of whom are poor. Despite this growing interest, rural people and especially the rural poor are little seen or heard; their environmental change experiences are thus misunderstood, and solutions proposed do not take into consideration the local context or experiences. There remains also a normative perspective which positions women as automatically vulnerable to environmental change, specifically vis-à-vis men. In doing so women’s experiences of environmental change are homogenised and men’s experiences are rendered invisible. Drawing on the case of Zimbabwe this study critically considers the experiences and perceptions of rural men and women to environmental change so as to ascertain gendered impacts and differential vulnerabilities. To capture fully the subjective lived experience of both men and women to environmental change, this study lends itself to qualitative research. Thus research methods such as semi-structured interviews, focus group discussions and gender analysis are central to the methodology. In terms of findings, this study argues against looking at environmental change as a technocratic subject accessible only from a global frame and accessed only by a technocratic few, proposing that the people experiencing environmental change at a local level should determine the environmental changes of communal concern. This study also highlights the importance of understanding the vulnerabilities of rural men and women within a well-conceived notion of context, taking into account rural disadvantage resulting from colonialism, and the current Zimbabwean crisis

Parallelism and divergence in immune responses: a comparison of expression levels in two lakes

Question: How do immune phenotypes differ between infected and uninfected wild individuals, and is the effect the same in different populations? Organisms: Threespine stickleback (Gasterosteus aculeatus) from two lake populations on the island of North Uist, Scotland, sampled in May 2015. Methods: For each fish, we recorded length, sex, reproductive status, condition, and parasitic infection. We measured the expression levels of eight genes that act as key markers of immune system function using qPCR, and then examined the relationship between measured factors and immune gene expression profiles within each population. Conclusions: Populations differed significantly in their immune gene expression profiles. Within each population, multiple factors, including condition, reproductive status, and Schistocephalus solidus infection levels, were found to correlate with expression levels of different arms of the immune system

Teachers' use of questioning and modelling comprehension skills in primary classrooms

Research suggests that children's understanding of text can be improved by the explicit teaching of those comprehension strategies that are used implicitly by skilled readers, particularly the use of self-regulating strategies to generate questions about text. This study of the teaching of comprehension in 51 London Key Stage 2 classrooms explores the extent to which comprehension strategies are explicitly taught within the literacy hour and the amount of opportunity which is provided for children to generate there own questions. Evidence from teacher interviews and classroom observations shows that direct teacher questioning, mostly in the form of 'teacher-led recitation', is both the most frequently advocated, and the dominant strategy used for teaching comprehension. When sharing books with children, teachers model the strategies which are used by skilled comprehenders, but they neither make these strategies explicit nor encourage children to generate their own questions about the text

Working in partnership through early support: distance learning text: working with parents in partnership (book chapter)

This is a chapter from the distance learning text for the 'Working in Partnership through Early Support' accredited training programme. "Our intention in this chapter... is to provide a theory of helping, known as the Family Partnership Model. It is based upon the notion that the most effective relationship between parent and helper is a partnership, as first discussed by Mittler, Cunningham and others in the 1970s. It is an explicit and relatively simple framework intended as a guide for all people working with children and their families. Having described the theory, we will look briefly at its implications for service development, training and professional support, the use of the Early Support materials in promoting partnership and the evidence for working in this way." - pp. 2-
