Hesitations About Special Divine Action: Reflections on Some Scientific, Cultural and Theological Concerns

The new interest in special divine action has led to a close reading of the great debates and discussions of the early modern period in an attempt to understand contemporary resistance to the notion of divine action, and to develop strategies for reaffirming the notion in a refined manner. Although continuing engagement with and evaluation of the Humean legacy on miracles and divine action will be of central importance to this programme of review, there are other issues that also need to be addressed. In this article I identify some of the factors that have caused or continue to cause difficulties for the articulation of a concept of special divine action and I suggest how they might be engaged

Correlating and predicting the air infiltration through the cracks of suspended timber floors

This paper shows that the visible gap length may be used as a physical parameter when correlating pressure difference to volume flow rate (or air velocity) through the cracks between floorboards and can be termed the Equivalent Crack Length. The crack widths, which previously have been determined separately from the edge effect coefficient and the laminar flow coefficient, were significantly different. When analysed graphically they can be shown to correlate by an empirical relationship. A generalised equation is proposed that, in conjunction with the empirical relationship, allows predictions to be made of the volume flow rate through the cracks between floorboards for a known pressure difference

Photon induced secondary electron emission

Numerical models for predicting photon-induced secondary electron emission are presented. The results are compared with experimental measurements made using a Co-60 gamma ray source

Exploring the democratic potential of online social networking: The scope and limitations of e-participation

Copyright © 2012 by the Association for Information Systems.The availability and promise of social networking technologies with their perceived open philosophy has increasingly inspired citizens around the world to participate in political activity on the Web. Recent examples range from opposing public policies, such as government funding cuts, to organizing revolutionary social movements, such as those in the Middle East and North Africa. Although online spaces create remarkable opportunities for various forms of political action, there are concerns over the power of existing institutions to control and even censor such interaction spaces. The objective of this article is to draw together different insights on the online engagement phenomenon, highlighting both its potential and limitations as a mechanism for fostering democratic debate and influencing policy making. We examine recent examples from Europe, the Middle East and Latin America. Finally, we summarize the implications of our work and outline directions for further research

An experimental study of surface pressure fluctuations in a separating turbulent boundary layer

Measurements of streamwise velocity fluctuation and surface pressure fluctuation spectra and wavespeeds are reported for a well-documented separating turbulent boundary layer. Because a portion of the acoustic pressure fluctuations is the same across the nominally two-dimensional turbulent flow, it is possible to decompose two microphone signals and obtain directly the turbulent flow contributions to the surface pressure spectra. The rms surface pressure fluctuation p' and spectra phi(omega) increase through the adverse pressure gradient attached flow region and the detached flow zone and scale on the maximum turbulent shearing stress tau(M); p'/tau(M) increases to the detachment location and decreases downstream due to the rapid movement of the pressure-fluctuation-producing motions away from the wall after the beginning of intermittent backflow. At lower frequencies for the attached flow phi(omega) is approximately omega to the -0.7 while phi(omega) is approximately omega to the -3 at higher frequencies. After the beginning of intermittent backflow, phi(omega) varies with omega at low frequencies and omega to the -3 at high frequencies; farther downstream the lower frequency range varies with omega to the 2.4. The surface pressure fluctuation celerity for the attached flow increases with frequency and agrees with the semi-logarithmic overlap equation of Panton and Linebarger. After the beginning of the separation process, the wavespeed decreases because of the oscillation of the instantaneous wavespeed direction and the streamwise coherence decreases drastically

A participatory filmmaking process with children with disabilities in rural India: Working towards inclusive research

Children with disabilities often experience exclusion within their communities, and this exclusion can extend into research processes. The United Nations Convention on the Rights of the Child, however, emphasizes that children of all abilities need to be involved as decision makers in matters affecting them. This article provides an in-depth description of the process of a participatory action research project carried out with children with disabilities from a rural village in India. It argues for the utility of participatory filmmaking as a research methodology that supports inclusion of children with disabilities as co-researchers in research and action processes. The different phases of the research project, namely the preparatory, participatory research, and the action phase, are made transparent along with the details of activities carried out within each phase. The technical and pragmatic challenges faced within this participatory filmmaking process are pointed out, and strategies used to negotiate challenges and adapt this methodology to fit context-specific needs are shared. This account of the complex, yet flexible and adaptable, participatory filmmaking process is presented as means to support critical and informed uptakes of participatory filmmaking for inclusive research practices with children with disabilities
