This study explores the potential impact of variation in forest habitats and management on Chuck-will’s-widow density

Diffusion and System Change - A Case Study of Innovations in a Course Management System

This case study in progress compares two stages of usage of a Course Management System at a private university: before a major functionality upgrade, and after. Here, we report the initial study of usage before the upgrade. It extends current research by taking into account prior use, and noting features (whether in the previous system or not) that attract new implementers. The focus of the study is on Perceived Characteristics of Innovations and management behaviors that facilitate effective implementation of system features. The instrument used by Van Slyke, Lou and Day will be used to study secondary adoption both before and after the upgrade, as described by Gallivan (2001). Results of the first phase of research will be available for presentation at the conference

Moving beyond boundaries: When user-centered design meets sociology

In this paper, we consider the potential of combining design, engineering and sociological perspectives with user perspectives, as part of a user-centered, inclusive design process. Our particular interest lies in the design of inclusive toys and games that disabled and non-disabled children can play together and which foster positive interactions between children across difference. We explore the challenges and opportunities associated with working in a transdisciplinary mode, where knowledge production evolves from dynamic tension between different disciplinary perspectives and those of non-academic stakeholders. We argue that the latter is of particular importance within any design process that seeks to provide accessibility and empower users. Such transdisciplinarity involves an upstream approach to the involvement of non-academic interests in the design process and knowledge production, rather than limiting the engagement of/with users to the dissemination end point stage of research (Barry, forthcoming). The paper draws upon two case studies of projects conducted by the authors. Both projects involve the use of co-operative inquiry [14] with children and we seek to extract the pedagogical implications of both projects for future design, including that within the field of ICT and digital technologies, with and for children

Inhibitory responses mediated by vagal nerve stimulation are diminished in stomachs of mice with reduced intramuscular interstitial cells of Cajal

Intramuscular interstitial cells of Cajal (ICC-IM) are closely associated with enteric motor nerve terminals and electrically coupled to smooth muscle cells within the gastric musculature. Previous studies investigating the role of ICC-IM in motor neurotransmission have used indiscriminate electric field stimulation of neural elements within the gastric wall. To determine the role of ICC-IM in transduction of vagally-mediated motor input to gastric muscles electrical and mechanical responses to selective electrical vagal stimulation (EVS) were recorded from gastric fundus and antral regions of wild type and W/WV mice, which lack most ICC-IM. EVS evoked inhibitory junction potentials (IJPs) in wild type muscles that were attenuated or abolished by L-NNA. IJPs were rarely evoked in W/WV muscles by EVS, and not affected by L-NNA. EVS evoked relaxation of wild type stomachs, but the predominant response of W/WV stomachs was contraction. EVS applied after pre-contraction with bethanechol caused relaxation of wild type gastric tissues and these were inhibited by the nitric oxide synthase inhibitor L-NNA. Relaxation responses were of smaller amplitude in W/WV muscles and L-NNA did not attenuate relaxation responses in W/WV fundus muscles. These data suggest an important role for ICC-IM in vagally-mediated nitrergic relaxation in the proximal and distal stomach.Elizabeth A. H. Beckett, Kenton M. Sanders and Sean M. War

A text become provisional: revisiting the capital of the ruins

This essay is a reexamination of Samuel Beckett's The Capital of the Ruins, the untransmitted radio script written for Raidió Éireann (now Raidió Teilifís Éireann) in 1946 following his work with the Irish Red Cross in Saint Lô. The first half of this essay is concerned with the archival and publishing history of the text. This section examines the variants introduced by various editors or publishers and makes a case for a definitive edition of the text based on the edited photocopy of the typescript held in the Beckett International Foundation archive at the University of Reading. The second half of this essay then uses this close attention to the text to reconsider the focus of The Capital of the Ruins and the extent to which the piece is more firmly directed towards socio-political aspects of post-neutrality Ireland than has previously been identified

Prediction of soil water retention properties using pore-size distribution and porosity

Several models have been suggested to link a soil's pore-size distribution to its retention properties. This paper presents a method that builds on previous techniques by incorporating porosity and particles of different sizes, shapes, and separation distances to predict soil water retention properties. Mechanisms are suggested for the determination of both the main drying and wetting paths, which incorporate an adsorbed water phase and retention hysteresis. Predicted results are then compared with measured retention data to validate the model and to provide a foundation for discussing the validity and limitations of using pore-size distributions to predict retention properties. </jats:p
