    The Advancement of New Theology Using New Science: The Three Key Concepts of Thomas Torrance

    Full text link
    The author begins with a selective outline of historical understandings of the concepts of space and time, in order to demonstrate their import for and engagement with theology. She then procedes to organize the three key concepts in Torrance\'s thought that are the most significant to the advancement of contemporary theology using insights from \"new science.\

    Improving the external validity of clinical trials: the case of multiple chronic conditions

    The U.S. Department of Health and Human Services vision and strategic framework on multiple chronic conditions (MCCs) incorporates recommendations designed to facilitate research that will improve our knowledge about interventions and systems that will benefit individuals with MCCs (or multimorbidity). The evidence base supporting the management of patients with MCCs will be built both through intervention trials specifically designed to address multimorbidity and identification of MCCs in participants across the clinical trial range. This article specifically focuses on issues relating to external validity with specific reference to trials involving patients with MCCs. The exclusion of such patients from clinical trials has been well documented. Randomized control trials (RCTs) are considered the “gold standard” of evidence, but may have drawbacks in relation to external validity, particularly in relation to multimorbidity. It may, therefore, be necessary to consider a broader range of research methods that can provide converging evidence on intervention effects to address MCCs. Approaches can also be taken to increase the usefulness of RCTs in general for providing evidence to inform multimorbidity management. Additional improvements to RCTs would include better reporting of inclusion and exclusion criteria and participant characteristics in relation to MCCs. New trials should be considered in terms of how they will add to the existing evidence base and should inform how interventions may work in different settings and patient groups. Research on treatments and interventions for patients with MCCs is badly needed. It is important that this research includes patient-centered measures and that generalizability issues be explicitly addressed.Journal of Comorbidity 2013;3(2)30–3

    Reversibility of cell surface label rearrangement

    Cell surface labeling can cause rearrangements of randomly distributed membrane components. Removal of the label bound to the cell surface allows the membrane components to return to their original random distribution, demonstrating that label is necessary to maintain as well as to induce rearrangements. With scanning electron microscopy, the rearrangement of concanavalin A (con A) and ricin binding sites on LA-9 cells has been followed by means of hemocyanin, a visual label. The removal of con A from its binding sites at the cell surface with alpha- methyl mannoside, and the return of these sites to their original distribution are also followed in this manner. There are labeling differences with con A and ricin. Under some conditions, however, the same rearrangements are seen with both lectins. The disappearance of labeled sites from areas of ruffling activity is a major feature of the rearrangements seen. Both this ruffling activity and the rearrangement of label are sensitive to cytochalasin B, and ruffling activity, perhaps along with other cytochalasin-sensitive structure, may play a role in the rearrangements of labeled sites

    Expanding the Supply of High Quality Public Schools

    Two levers that play critically important roles in determining how quickly and consistently successful schools and design models can be replicated. One is the degree of managerial responsibility, support, and control the organization chooses to exercise. The other is related to specificity of school design.This paper examines the school development landscape in the context of these levers, with examples of organizations that have chosen different paths with different tradeoffs and outcomes

    On the Two-point Correlation of Potential Vorticity in Rotating and Stratified Turbulence

    Full text link
    A framework is developed to describe the two-point statistics of potential vorticity in rotating and stratified turbulence as described by the Boussinesq equations. The Karman-Howarth equation for the dynamics of the two-point correlation function of potential vorticity reveals the possibility of inertial-range dynamics in certain regimes in the Rossby, Froude, Prandtl and Reynolds number parameters. For the case of large Rossby and Froude numbers, and for the case of quasi-geostrophic dynamics, a linear scaling law with 2/3 prefactor is derived for the third-order mixed correlation between potential vorticity and velocity, a result that is analogous to the Kolmogorov 4/5-law for the third-order velocity structure function in turbulence theory.Comment: 10 pages, to appear in Journal of Fluid Mechanics (2006

    Welfare Reform and Lone Parents in the UK

    Get PDF
    The last thirty years saw dramatic increases in the proportion of children living in lone parent households. In 1997 the incoming Labour government initiated a series of policy reforms aimed at reducing this high level of child poverty. A key element of their strategy was a move towards increasing employment rates among families with children by a combination of increased in-work support through the Working Families Tax Credit and active case management of the population on welfare through the New Deal for Lone Parents. The assessment of this policy reform agenda has focused to date mainly on lone mothers’ employment and poverty. In this paper we extend this to include at the impact on the numbers of lone parent families and a range of outcomes for mothers and children. We cover mothers’ mental well-being and health, child outcomes and relationship patterns. As well as representing the basic facts about employment incomes and hours of work. Our results show there was no significant impact of these policy reforms on family structure. Mothers malaise scores are, unsurprisingly, very high on family break up but they tend to recover after around 2 years. WFTC is found to reduce the spike of high malaise co-incident with the transition into lone parenthood but to have no longer term effects. This decline in malaise is strongly associated with improved financial indicators. Adolescent children in lone parents families report lower self-esteem, more unhappiness, lower quality relationships with the mother and a number of worse or risky behaviours. Difference-in-difference techniques suggest a marked narrowing if these gaps since WFTC. The magnitude of these changes are quite large, half of the gap in self-esteem and unhappiness scores and in truanting, smoking and planning to leave school at age 16 are eliminated after the policy reforms. This strongly suggests that the increases in incomes and employment associated with the reforms have profoundly changed the quality of life children in lone parent families.Welfare reform, lone parents, tax Credits
