Social Justice Through the Lens of the Cross: A Case for a Biblical Foundation of Social Work

Social work values social justice, as the profession promotes the well-being of society and the rights each person holds. Although social justice is a core value of social work, it is necessary to address the value’s foundation, and questioning the “why” behind social justice calls for a deeper understanding of social work. Using the “Inside-Out” apologetic approach demonstrates how the secular grounding of social work neglects to provide the foundation required to make claims on the necessity of social justice. A Christian foundation, however, offers the grounding needed to support the values and mission of social work, and it is valuable to support a Christian understanding of social work

Subordination in Children’s Writing

This paper reports an investigation into the use of subordinate clauses in the writing of a class of seven to nine year old children when attempting five different writing tasks. The investigation was undertaken in part-response to an inspection report on the school by the Office for Standards in Education (Ofsted) which recommended that the school should extend the writing skills of pupils in this age-range. The importance of developing subordination in writing is related to previous research and to evidence from reviews of Ofsted inspection evidence. The different patterns of subordination are discussed, between tasks and pupils and in relation to variation in the writing of individual children when tackling the different tasks. The paper ends by suggesting how similar informal investigations can assist schools in promoting writing development. It also outlines how the teaching approaches outlined in the National Literacy Strategy will provide opportunities for this promotion, particularly by exploiting links between reading and writing

Researchers’ opinions about ethically sound dissemination of BCI research to the public media

BCI research and (future) applications raise ethical questions. A websurvey among 144 BCI researchers identified disseminating BCI research to the public media as a central topic. Most researchers felt that BCI scientists must responsibly communicate with the media and that general ethical guidelines on BCI research and application are needed within the next 5 years. We recommend further debate on ethical aspects related to BCI and the development of guidelines

Clustering and Micro-immiscibility in Alcohol-Water Mixtures: Evidence from Molecular Dynamics Simulations

We have investigated the hydrogen-bonded structures in liquid methanol and a 7:3 mole fraction aqueous solution using classical Molecular Dynamics simulations at 298K and ambient pressure. We find that, in contrast to recent predictions from X-ray emission studies, the hydrogen-bonded structure in liquid methanol is dominated by chain and small ring structures. In the methanol-rich solution, we find evidence of micro-immiscibility, supporting recent conclusions derived from neutron diffraction data.Comment: 5 pages, 4 figure

Discrete--time ratchets, the Fokker--Planck equation and Parrondo's paradox

Parrondo's games manifest the apparent paradox where losing strategies can be combined to win and have generated significant multidisciplinary interest in the literature. Here we review two recent approaches, based on the Fokker-Planck equation, that rigorously establish the connection between Parrondo's games and a physical model known as the flashing Brownian ratchet. This gives rise to a new set of Parrondo's games, of which the original games are a special case. For the first time, we perform a complete analysis of the new games via a discrete-time Markov chain (DTMC) analysis, producing winning rate equations and an exploration of the parameter space where the paradoxical behaviour occurs.Comment: 17 pages, 5 figure

Comparison of interference-free numerical results with sample experimental data for the AEDC wall-interference model at transonic and subsonic flow conditions

Numerical results obtained from two computer programs recently developed with NASA support and now available for use by others are compared with some sample experimental data taken on a rectangular-wing configuration in the AEDC 16-Foot Transonic Tunnel at transonic and subsonic flow conditions. This data was used in an AEDC investigation as reference data to deduce the tunnel-wall interference effects for corresponding data taken in a smaller tunnel. The comparisons were originally intended to see how well a current state-of-the-art transonic flow calculation for a simple 3-D wing agreed with data which was felt by experimentalists to be relatively interference-free. As a result of the discrepancies between the experimental data and computational results at the quoted angle of attack, it was then deduced from an approximate stress analysis that the sting had deflected appreciably. Thus, the comparisons themselves are not so meaningful, since the calculations must be repeated at the proper angle of attack. Of more importance, however, is a demonstration of the utility of currently available computational tools in the analysis and correlation of transonic experimental data

Semiempirical method for predicting vortex-induced rolling moments

A method is described for the prediction of rolling moments on a wing penetrating a vortex velocity field generated by a large aircraft. Rolling moments are determined from lifting pressure coefficients computed with an inviscid-flow linear panel method. Two empirical corrections are included to account for the lifting efficiency of an airfoil section and the local stall on the wing. Predicted rolling moments are compared with those from two windtunnel experiments. Results indicate that experimental rolling moments, for which the Reynolds number of the following wing is low, should be interpreted with caution
