Matteus 18:15�20: 'n Diachroniese en sinchroniese ondersoek met besondere verwysing na kerklike dissipline

Matthew 18:15�20: A diachronic and synchronic investigation with special reference to church discipline It is well known that gospel material consists of traditional matter as well as the evangelists' own input. A thorough exegesis should contain both the aspects of the investigation into the growth of the tradition (diachrony), and the study of the text in its final stage (synchrony). Matthew 18:15�20 is subjected to such an approach. As part of the diachrony these verses are studied by means of the historical critical paradigm. Special attention is paid to source and redaction criticism. Under the synchronic aspect this pericope is investigated structurally, historically and theologically. Discourse and narrative analyses are used for the structural component

The Sanctity of human life. A perspective from New Testament anthropology

The article deals with sanctity of life issues such as abortion, euthanasia, treatment of the disabled, war, and capital punishment. These matters are not treated individually but collectively from the perspective of New Testament anthropology. Having taken care of a few methodological considerations, the main focus falls on a discussion of man as sinner, man in Christ, and the category of the least

Stream-field interactions in the magnetic accretor AO Piscium

UV spectra of the magnetic accretor AO Psc show absorption features for half the binary orbit. The absorption is unlike the wind-formed features often seen in similar stars. Instead, we attribute it to a fraction of the stream that overflows the impact with the accretion disk. Rapid velocity variations can be explained by changes in the trajectory of the stream depending on the orientation of the white-dwarf's magnetic field. Hence we are directly observing the interaction of an accretion stream with a rotating field. We compare this behavior to that seen in other intermediate polars and in SW Sex stars.Comment: Accepted for ApJ; 6 page

Utilizing formal innovation models to support and guide industry innovation projects

CITATION: van Zyl, H., du Preez, N.D., & Schutte, C. 2007. Utilizing formal innovation models to support and guide industry innovation projects. South African Journal of Industrial Engineering 18(2): 203-219, doi: http://dx.doi.org/10.7166/18-2-127.The original publication is available at http://sajie.journals.ac.zaENGLISH ABSTRACT: The high failure rate of innovation projects indicates that many companies are not getting the full benefit from their innovation projects [1], [2]. A research project was carried out during 2005 that explored and compared the existing formal models for supporting innovation, in order to address the identified problem. It proposed guidelines for improving and refining innovation projects. A case study that focused on the front-end of product innovation in the wine industry and the applicability of the formal W-model [3] to innovation activities was used to evaluate how formal innovation models can indeed effectively support industry innovation projects. The innovation life cycle was used to categorize a number of innovation frameworks for product, process, and enterprise innovation. Further research should focus on extending the case study to other industries, such as the automotive sector.AFRIKAANSE OPSOMMING: Die groot aantal onsuksesvolle innovasie projekte dui daarop dat maatskappye nie die volle voordele uit hul innovasie projekte kry nie [1], [2]. ’n Navorsingsprojek is gedurende 2005 uitgevoer om bestaande formele innovasie modelle te evalueer, ondersoek, en vergelyk, met die doel om bogenoemde probleem aan te spreek en riglyne voor te stel wat innovasie sal bevorder en verfyn. ’n Gevallestudie, wat fokus op produkinnovasie in die wyn-industrie, is uitgevoer om die toepaslikheid en effektiewe ondersteuning van die formele W-model [3] op spesifieke innovasie aktiwiteite te evalueer. Die innovasie-lewensiklus is ook gebruik om ’n aantal innovasie-raamwerke te kategoriseer in afdelings vir produk-, onderneming- en proses-innovasie. Toekomstige navorsing behoort te fokus op ’n uitbreiding van die gevallestudie na ander industrië soos die motorindustrie.http://sajie.journals.ac.za/pub/article/view/127Publisher's versio

Analytical treatment of interacting Fermi gas in arbitrary dimensional harmonic trap

We study normal state properties of an interacting Fermi gas in an isotropic harmonic trap of arbitrary dimensions. We exactly calculate the first-order perturbation terms in the ground state energy and chemical potential, and obtain simple analytic expressions of the total energy and chemical potential. At zero temperature, we find that Thomas-Fermi approximation agrees well with exact results for any dimension even though system is dilute and small, i.e. when the Thomas-Fermi approximation is generally expected to fail. In the high temperature (classical) region, we find interaction energy decreases in proportion to T^(-d/2), where T is temperature and d is dimension of the system. Effect of interaction in the ground state in two and three-dimensional systems is also discussed.Comment: 15 pages, 4 figure

Simulations of Spinodal Nucleation in Systems with Elastic Interactions

Systems with long-range interactions quenched into a metastable state near the pseudospinodal exhibit nucleation that is qualitatively different than the classical nucleation observed near the coexistence curve. We have observed nucleation droplets in our Langevin simulations of a two-dimensional model of martensitic transformations and have determined that the structure of the nucleating droplet differs from the stable martensite structure. Our results, together with experimental measurements of the phonon dispersion curve, allow us to predict the nature of the droplet. These results have implications for nucleation in many solid-solid transitions and the structure of the final state
