During services of the Reformed Churches of South Africa (RCSA), certain psalms and Biblical hymns are used frequently, while others are almost never used. The objective of this study is to determine how the Psalter of 2003 can be used optimally. The model of Zerfass is used for the investigation. The final results of the study are presented in the form of a model that can enrich the optimal use of the Psalter 2003 as means of communication in the liturgy of the RCSA. In Chapters 2 and 3, a basic-theoretical investigation is conducted, with reference to perspectives from Scripture and history. The investigation reveals that music and songs had already played an important role in the church of the Old Testament, and that the Psalms had had a significant influence on the liturgy and the faith. In the New Testament, new hymns are found that supplement those from the Old Testament. The form in which these hymns were composed, was closely connected to the context whence these songs arose. The communication that a hymn effects, is achieved jointly by word and music, in the church of the New Testament and subsequently. Since the Reformation, a degree of separation arose between the songs used in the church and outside, but mutual influences are observed. In Chapters 4 and 5, attention is paid to metatheoretical perspectives, first in communication science, then in hymnology. It is in their singing that the congregation participates in the worship of a church service. Such singing is indeed the basic form of participation, which promotes communication among members of the congregation. In judging a metrical version of a Psalm, attention should especially be paid to the content, style of the text and the melody. In the empirical investigation, qualitative and quantitative methods are used. The investigation proceeds in three phases. In the first phase, information is obtained about the hymns that were sung in a number of congregations in the course of a year. In the second phase, a questionnaire was set and sent to ministers, organists and members of congregations. In the final phase, interviews were conducted with ministers and organists from five congregations. The data show that the hymn occupies an important place in the liturgy. However, the investigation reveals that this point of departure is not fully realised in practice, and some shortcomings are identified. In particular, there is a need for extension of the hymnody, especially by hymns from the New Testament. In Chapter 7, an indication is given of the factors that constrain the optimal use of the Psalter 2003 as means of worship in the church service. The most important problems are: • the incomplete utilisation of the full collection of hymns in the Psalter, • the underuse of the 2001 metrical version, • the repeated use of a small subset of hymns, • problems with the melodies and liturgical usefulness, • limitations in the training of ministers and organists, • resistance to the 2001 metrical version, • a lack of proper programmes to practice the new hymns, and • inadequate support and encouragement by church councils in respect of improving the skills of organists. In view of these problems, a model is proposed, which identifies the relationships among the role players / elements necessary to promote worshipping through singing: • the users of the Psalter 2001, viz. Ministers, organists and members of the congregations, together with the role of the church council, • the Psalter 2003 as hymn book, and • the possible extension of the current corpus of hymns. / Thesis (Ph.D. (Liturgics))--North-West University, Potchefstroom Campus, 2009.

With the shift to a system of floating exchange rates among major currencies in 1973, there was a shift of emphasis from the external balance to the exchange rate determination. Attempts have been made to explain the behavior of the exchange rate both theoretically and empirically over the last 20 years. Most models could not explain what happened, as in the 1980s, when the exchange rate moved a lot. Alternative models based on different approaches give different explanations and suggest different policies. This study examines the implications of the models to see what light the empirical results shed on the issues. Results of this study indicate that both monetary and real factors are important in explaining the behavior of the exchange rate, but the results generally support the view of the monetary approach.

The broad objective of this study is to examine how assortment factors and category performance are related within the context of specialty retailing. This study formulates two clusters of research questions. The first cluster of research questions focuses on product assortment in general, for example assortment variety and composition. The second cluster of research questions concentrates on a specific area of product assortment, that is, private label products. An organic retailer in Australia collaborates by providing its assortment records and sales reports. The Australian organic retailing industry is an ideal candidate for this study for 1) it is specialty retailing, and 2) the supply situation allows organic retailers considerable flexibility to experiment with different assortment compositions. This study analyses store level cross sub category data and, to supplement this, it conducts a qualitative study and collects field data. Included in the cross sub category analyses are approximately 140 to 180 organic sub categories. The results show that assortment variety has a positive influence on sub category sales. The strength of this positive relationship varies across different sub category types, for example food or non-food. For the private label analyses, the results show that, within the focal store, private label SKUs are more likely to be present in sub categories with larger sales and with supermarket competition present. This study also finds that a deeper manufacturer brand assortment hurts private label performance. This study contributes to a body of cross category empirical generalisations about the complex decisions retailers face by examining the effects of assortment decisions within the context of specialty retailing. It provides some clear empirical evidence for how assortment factors and sub category performance are related through an empirical investigation in a bricks and mortar retail environment. In addition, it tests the generalisability of extant private label research beyond the much discussed conventional supermarket industry and convenience consumer goods contexts.

This final thesis covers the basics of artificial neural networks, with focus on supervised learning, pruning and the problem of achieving good generalization ability. An empirical investigation is conducted on twelve dierent problems originating from the Proben1 benchmark collection.The results indicate that pruning is more likely to improve generalization if the data is sensitive to overtting or if the networks are likely to be trapped in local minima.

The study investigated how a pedagogic change process is managed by the divergent Haredi and Modern Orthodox streams of Orthodox Jewish schooling. Its literature study looked at the classical forms of historic Jewish pedagogy and how they have adapted to internal and external dynamics. It also examined how contemporary Orthodox schooling, specifically, is an amalgam of a variety of responses, reactions and adaptations to the radically changed landscape of modernity. The influence of the modern student profile was examined along with the affects of the inclusion of secular studies into the modern Jewish syllabus. The appropriateness of new interactive methods and technologies and the specialized teacher training they require were also explored. A qualitative study of the expert opinions of six contemporary experts was conducted and thematically analyzed along with an analysis of material from two file-sharing websites. Recommendations for educational practice and further research were proposed. / Educational Studies / M. Ed. (Comparative Education)
