An appreciative inquiry into the transformative learning experiences of students in a family literacy project
No full textEducational discourse has often struggled to genuinely move beyond deficit-based language. Even action research, a predominant model for teacher development, starts with the identification of a problem (Cardno 2003). It would appear that the vocabulary for a hope-filled discourse which captures the imagination and infiuences our future educational activity seems to have escaped us. Moreover, we seem bereft of educational contexts where the experience for students is holistic and transformative

Parallel transmit pulse design for saturation homogeneity (PUSH) for magnetization transfer imaging at 7T
Get PDFPURPOSE: This work proposes a novel RF pulse design for parallel transmit (pTx) systems to obtain uniform saturation of semisolid magnetization for magnetization transfer (MT) contrast in the presence of transmit field [Formula: see text] inhomogeneities. The semisolid magnetization is usually modeled as being purely longitudinal, with the applied [Formula: see text] field saturating but not rotating its magnetization; thus, standard pTx pulse design methods do not apply. THEORY AND METHODS: Pulse design for saturation homogeneity (PUSH) optimizes pTx RF pulses by considering uniformity of root‐mean squared [Formula: see text] , [Formula: see text] , which relates to the rate of semisolid saturation. Here we considered designs consisting of a small number of spatially non‐selective sub‐pulses optimized over either a single 2D plane or 3D. Simulations and in vivo experiments on a 7T Terra system with an 8‐TX Nova head coil in five subjects were carried out to study the homogenization of [Formula: see text] and of the MT contrast by acquiring MT ratio maps. RESULTS: Simulations and in vivo experiments showed up to six and two times more uniform [Formula: see text] compared to circular polarized (CP) mode for 2D and 3D optimizations, respectively. This translated into 4 and 1.25 times more uniform MT contrast, consistently for all subjects, where two sub‐pulses were enough for the implementation and coil used. CONCLUSION: The proposed PUSH method obtains more uniform and higher MT contrast than CP mode within the same specific absorption rate (SAR) budget

Reclaiming rural character: conservation, conflict, and the nostalgic landscapes of Orcas Island, Washington
No full textThis dissertation takes an ethnographic approach to examining the meanings of rural character on Orcas Island, in San Juan County, Washington. In spite of the challenges facing productive agriculture in the county, achieving rural character remains the stated goal of county planning efforts, environmental groups, affordable housing advocates, and private landowners. Drawing from the anthropology of landscape, political ecology, and critical readings of memory and history, this project examines the definitions of rurality in a place where farming and other types of labor have been overshadowed by real estate speculation and tourism. More broadly, this work argues that land management is a highly subjective process that engages aesthetic preferences, popular ecological models, cultural conceptions of property, and concerns with labor and affordability. In particular, looking at conservation easements can highlight the ways in which nostalgic longings for particular landscapes can be elevated to the level of political economic conflict, in which only certain individuals are able to shape the land according to personally or culturally shared visions.Ph.D.Includes bibliographical references (p. 272-284)by Sharon L.

“This is your life you have to live with the memories”: Older migrant women’s reflections on living with the past
No full textMemories collected across the life-course often inform our sense of who we are and what is important to us, as we grow older. This article draws on the findings of two qualitative life-history research projects that set out to explore older UK migrant women’s quality of life across the life course. It has two main aims. One aim is to contribute to existing theorizations of social memory. Another aim is to show the extent to which migrant women’s memories of life-altering events influence their satisfaction with life as they grow older. The article concludes by arguing for an approach to the study of ageing that is sensitive to the impact of memories on our experiences of growing older
Effect of changes in testing parameters on the cost-effectiveness of two pooled test methods to classify infection status of animals in a herd
No full textMonte Carlo simulation was used to determine optimal fecal pool sizes for identification of all Mycobacterium avium subsp. paratuberculosis (MAP)-infected cows in a dairy herd. Two pooling protocols were compared: a halving protocol involving a single retest of negative pools followed by halving of positive pools and a simple protocol involving single retest of negative pools but no halving of positive pools. For both protocols, all component samples in positive pools were then tested individually. In the simulations, the distributions of number of tests required to classify all individuals in an infected herd were generated for various combinations of prevalence (0.01, 0.05 and 0.1), herd size (300, 1000 and 3000), pool size (5, 10, 20 and 50) and test sensitivity (0.5–0.9). Test specificity was fixed at 1.0 because fecal culture for MAP yields no or rare false-positive results. Optimal performance was determined primarily on the basis of a comparison of the distributions of numbers of tests needed to detect MAP-infected cows using the Mann–Whitney U test statistic. Optimal pool size was independent of both herd size and test characteristics, regardless of protocol. When sensitivity was the same for each pool size, pool sizes of 20 and 10 performed best for both protocols for prevalences of 0.01 and 0.1, respectively, while for prevalences of 0.05, pool sizes of 10 and 20 were optimal for the simple and halving protocols, respectively. When sensitivity decreased with increasing pool size, the results changed for prevalences of 0.05 and 0.1 with pool sizes of 50 being optimal especially at a prevalence of 0.1. Overall, the halving protocol was more cost effective than the simple protocol especially at higher prevalences. For detection of MAP using fecal culture, we recommend use of the halving protocol and pool sizes of 10 or 20 when the prevalence is suspected to range from 0.01 to 0.1 and there is no expected loss of sensitivity with increasing pool size. If loss in sensitivity is expected and the prevalence is thought to be between 0.05 and 0.1, the halving protocol and a pool size of 50 is recommended. Our findings are broadly applicable to other infectious diseases under comparable testing conditions.ID: S0167587710000085; M3: Article; Accession Number: S0167587710000085; Author: Locksley L. McV.

Continuing Professional Development and Farm Business Performance
Get PDFEconomic and social pressures are transforming farm businesses and the structure of the agricultural industry, consequently it is presumed that farm management skills are under intense pressure. This creates a need for effective interaction between knowledge management and the actions taken by farm decision makers. However a definition of “successful farm business performance” is not easy to find and this, combined with literature that deals with managerial tasks in isolation, does not provide a clear picture for the farm manager pursuing self development. Farm businesses vary considerably in their attributes and resource base and the plethora of measurable factors mean that the manager needs to be able to identify what to measure and why on his own farm. In the UK it appears that most of the measures used in farming do not take into account the customer or human factors alluded to in other industries. Development of the skills and abilities of the decision makers to utilise techniques, interpret measures and relate them to their own business needs is increasingly important. The preliminary investigations described in this paper indicate that farmers and farm managers are aware of business management techniques but do not appear to integrate them fully into their own businesses.Farm Management, Teaching/Communication/Extension/Profession,
