Some Barthian perspectives on the present science-religion debate: What is the place

As an example of the context-relatedness of Barth's work, this article compares his crisis theology with Heidegger's philosophy of Being. Further examples are Barth's reaction to the modernism of his time, with its accent on rationalism (see his critique of Kant), and the influence of subjective theology. In spite of his condemnation of natural theology, Barth could make a unique contribution to the current science-theology debate. His reading of the creation story and the way he views (transcends) the literal text in order to experience the Word of God as an event through that text, is a case in point. This approach, too, is comparable with certain aspects of Heidegger's work. Barth's reaction to the natural theology of his day was equally tied to that context. His particular target was the theology of that era which he interpreted as “natural theology”. To Barth, natural theology is metaphor for self-assertive, autonomous human beings who, via reason, manipulate the church, the Word and tradition.HTS Theological Studies Vol. 63 (4) 2007: pp. 1447-147

Self-transcendence and Eros: The human condition between desire and the infinite

This article treats self-transcendence – like all transcendence – as a fact of human life. Inter alia this means that the human mind perforce operates in terms of binary concepts such as finitude–infinity, inner world–outside world, self–other, desire–fulfilment, separation–union and the like. We find these concepts in most myths of origin. The concept of desire (Eros), combining unfulfilment and the infinite, particularly epitomises self-transcendence. Ralph Waldo Emerson is cited as a precursor of the mid-19th century transcendentalists, whose ideas are resurfacing in present-day secular spirituality. In this article, we examined desire in the Christian conception of the Fall as envisioned by the Jewish philosopher Martin Buber and by Hegel, who integrates mind and nature in his philosophy of Spirit. The works of Emmanuel Levinas and Paul Ricoeur are used as points of reference to help us understand self and other in a framework of self-transcendence. The impact of these ideas on a postmetaphysical epistemology was also explored. Affectivity is a neglected area in Western thought and displays the same infinitude as rationality. The article concluded with present-day strategies of self-construction in a techno-scientific consumer culture

Reformulating the Hoogendoorn-Bovy predictive dynamic user-optimal model in continuum space with anisotropic condition

Hoogendoorn and Bovy (2004) developed an approach for a pedestrian user-optimal dynamic assignment in continuous time and space. Although their model was proposed for pedestrian traffic, it can also be applied to urban cities. The model is very general, and consists of a conservation law (CL) and a Hamilton–Jacobi–Bellman (HJB) equation that contains a minimum value problem. However, only an isotropic application example was given in their paper. We claim that the HJB equation is difficult to compute numerically in an anisotropic case. To overcome this, we reformulate their model for a dense urban city that is arbitrary in shape and has multiple central business districts (CBDs). In our model, the minimum value problem is only used in the CL portion, and the HJB equation reduces to a Hamilton–Jacobi (HJ) equation for easier computation. The dynamic path equilibrium of our model is proven in a different way from theirs, and a numerical algorithm is also provided to solve the model. Finally, we show two numerical examples under the anisotropic case and compare the results with those of the isotropic case.postprin

Synthesis and characterization of silica-encapsulated iron oxide nanoparticles

Session PD: Structured MaterialsThe properties of magnetic core-shell nanoparticles greatly depend on their core sizes and shell materials. Silica shell can prevent the magnetic nanoparticles from corrosion and agglomeration. In addition, the hydrolyzed silica can provide silanol groups to facilitate surface biofunctionalization. In this paper, superparamagnetic Fe3O4 nanoparticles coated with SiO2 shell were prepared by a one-pot water-in-oil microemulsion method. Transmission electron microscopy (TEM), scanning electron microscopy (SEM), and vibrating sample magnetometry (VSM) were utilized to characterize the morphology and magnetic properties of the synthesized nanoparticles. The results indicated that by tuning the water/surfactant molar ratio (Wo) of the microemulsion system, core size of the resulting Fe3O4 nanoparticles can be altered. The size-controllable silica-encapsulated Fe3O4 superparamagnetic nanoparticles have great potential to be applied as multifunctional tracer materials for magnetic particle imaging (MPI).published_or_final_versio

Capping-ligands-induced synthesis of non-spherical magnetite nanoparticles for hyperthermia and their biocompatibility study

This study aims to use different kinds of capping ligands (oleic acid, oleylamine, 1,2-tetradecanediol, decanoic acid, and lauric acid) for synthesis by thermal decomposition and to adjust the morphology of magnetite nanoparticles into non-spherical shape. The nanoparticle products are characterized using TEM, EDX, electron diffraction, SEM, and VSM. The synthesized nanoparticles show typical superparamagnetic behavior with a saturation magnetization value of 54 emu/g. A comparative cytotoxicity study is performed on human hepatoma cell lines and immortalized normal human liver cell lines to investigate biocompatibility of nanoparticles for hyperthermia application.postprin

Parental relatedness and parasitoid sex ratios under local mate competition

Sex ratio theory predicts that, under local mate competition, a more female‐biased offspring sex ratio will be produced by females when their relatedness to their mates is closer. We assess how the sexual composition of broods responds to mother–mate relatedness using Goniozus legneri Gordh (Hymenoptera: Bethylidae), a parasitoid wasp that has biased sex ratios due to local mate competition. Relatedness was varied by providing virgin females with a mate that was either a sibling, a non‐sibling from the same strain, from a strain with geographically similar origin or from a strain with geographically distant origin. The sex ratios among broods produced by mothers that had mated with a sibling or a same‐strain male were similar and were more biased than broods produced by females mated with males from a different strain. Brood sex variances were higher after mating with different‐strain males. Previous evaluations of parasitoid sex ratio responses to mate relatedness have not found the patterns predicted, possibly because the species investigated can control progeny sex ratio but cannot discriminate kin. In contrast, female G. legneri appear to possess both these abilities and appears to respond to mate relatedness in qualitative agreement with theoretical predictions
