TL;DR: In this article, the effect of ion beam energy, beam current, charge, target thickness and atomic number of the target metal on abnormally high X-ray yields from the fluorides of some transition metals was confirmed.
Abstract: Previously reported abnormally high X-ray yields from the fluorides of some transition metals were confirmed. Using proton beams and beams of the molecule-ion 1H2+, at equivalent proton energies between 400 and 2000 keV the conditions for the production of abnormally high X-ray yields were studied for the effect of ion beam energy, beam current, charge, target thickness and atomic number of the target metal. The effect was probably due to buildup of potential and discharge with the production of a flux of energetic electrons, with an energy distribution peaking above 10 keV.

TL;DR: In this paper, the authors argue that the developmental career theories of Ginzberg and Super are essentially mechanistic, ignore social influences, and overemphasize the role of the individual.
Abstract: Naicker in his recently published article, [South African Journal of Psychology, 1994,24(1)], provides a useful argument for the importance of adopting a psycho-social approach to career counselling in South African schools. He correctly states that environmental factors are important in our understanding of career choice in South Africa, but argues that developmental career theories are deficient in this regard and are essentially mechanistic, ignore social influences, and overemphasize the role of the individual. To what extent do developmental career theories reflect these characteristics? Naicker's criticisms appear to be aimed at the career theories of Ginzberg, Ginsburg, Axelrad and Herma (1951) and Super, Crites, Hummel, Moser, Overstreet and Warnath (1957). This is unfortunate as both references are generally regarded as of historical interest. Naicker fails to acknowledge the changes in career theory as evinced in revisions in the last two decades (Super, 1980, 1990). Furthermore, Naicker has neglected to consider Gottfredson's (1981) developmental theory of occupational aspirations and Vondracek, Lerner and Schulenberg's (1986) developmental-contextual approach to career development. It is difficult to consider the developmental career theories of Ginzberg and Super as mechanistic when such theories are primarily organismic in that they regard individuals as active agents in shaping their careers and giving meaning to their world rather than passive reactors to environmental circumstances. Here the context is viewed as facilitating or inhibiting career progression (Vondracek et al. 1986). However, Super's reformulation of his career theory has moved toward a transactional view as reflected in his LifeCareer Rainbow (Super, 1980) and Archway Model (Super, 1990). These models underscore the interaction of situational, historical, socio-economic, psychological and biological determinants in the career-shaping process. Super presently conceptualizes a person's career as the changing constellation of all the life roles that a person plays, a view that Naicker propounds when he states that 'career counsellors need to impress upon school-Ieavers that work, income, and self-esteem need not come from one source only namely, full-time paid employment' (p. 33). While earlier career developmental theories may well have viewed occupational choice as a 'hard, external objective kind of reality which is similar for most individuals' (p. 31), Super's conceptualization of role salience and the relative importance of work for different individuals explicitly addresses this misconception. Nor do modern developmental career theories adhere to a 'rigid interpretation' (p. 31) of their sequential components. Indeed, Super conceptualizes a recycling of the developmental phases a person passes through. He views environmental and personal factors as encouraging both maxiand S.-Afr. Tydskr. Sielk. 1994,24(4)

TL;DR: In this paper, the classes of strongly prime, uniformly strongly prime and superprime hemirings are defined and shown to be special classes, and intersection properties of the radicals generated by these classes are studied and related to α-ideas.
Abstract: The classes of strongly prime, uniformly strongly prime and superprime hemirings are defined and shown to be special classes. Intersection properties of the radicals generated by these classes are studied and related to α-ideas. Hemiring radicals and ring radicals of rings are shown to be identical for these three radical concepts.

TL;DR: In this article, a hierarchical morphological analysis which mirrors word-formation processes cannot be conducted without acknowledging the existence of the stem (or base), i.e. that meaningful part of a word which is neither a grammatical morpheme nor a root, and which therefore occupies some sort of in-between status.
Abstract: The aim of this article is to determine and to classify the various types of morphemes found in the word structure of Tswana; and to determine how they are hierarchically structured in word. These issues are investigated by comparing and evaluating the views of a number of linguists who have focused on morphology. Special attention is given to the component called the stem (or base), i.e. that meaningful part of a word which is neither a grammatical morpheme nor a root, and which therefore occupies some sort of in-between status. Reasons are given for acknowledging the notion of stem (word correlate) as an intermediary morphological component. It is concluded that a hierarchical morphological analysis which mirrors word-formation processes cannot be conducted without acknowledging the existence of the stem. The acknowledgement of the stem as a morphological component does not affect the status of the word in any way.

TL;DR: Slabbert and Levin this paper analysed expenditure patterns of black households in the Vaal Triangle Complex in the Eastern Cape, and found that black households spend more than 80% of their income on groceries.

TL;DR: In the first phase of the research process, namely observation towards a problem statement, this paper identified a problem which needs further research: there is a discrepancy between the religious understanding of peace by the church leaders and the people on grassroots level.
Abstract: The objective of this article is to progress descriptively within the first phase of the research process, namely observation towards a problem statement. On the basis of interviews with Dr LouwAlberts and Archbishop Desmond Tutu, literature, a survey on violence by the HSRC, and press reports we describe the role of Christian church leaders in the peace process which culminated in the National Peace Accord. Our research identified a problem which needs further research: there is a discrepancy between the religious understanding of peace by the church leaders and the religious understanding of peace by the people on grassroots level.

TL;DR: In this article, the pioneering work of Parasuraman, Zeithaml and Berry on service quality is used as a framework to investigate the relative influence of service quality dimensions on overall perceptions of Service quality in the banking industry.
Abstract: Quality is an extremely difficult concept to define, describe and measure. Consequently, few academics and authors have attempted to model it and research findings on its influence on key business variables such as profitability and market share are confusing and inconclusive. These problems are compounded in the service sector where the use of objective measures of quality is almost impossible. In this study the pioneering work of Parasuraman, Zeithaml and Berry on service quality is used as framework to investigate the relative influence of service quality dimensions on overall perceptions of service quality in the banking industry. The empirical results show that empathy, assurance and reliability are the service quality dimensions which exert the most influence on consumers' evaluations of overall service quality.
