Clinical experience with an epoxy resin adhesive for direct bonding of orthodontic attachments*

KIMAn epoxy resin formulation developed in the Dental Research Unit has been subjected to further clinical trials. Six patients, were used in the study. They were divided into two age groups and all the teeth, including the first molars, bonded. Rubber dam was used to keep the crowns dry during the setting period of the resin. In the younger group the mean failure rates were 27 per cent for anterior teeth and 70 per cent for the first molars. In the older group these rates were 11 per cent for incisors, 11 per cent for canines, 20 per cent for premolars and 20 per cent for first molars. While no figures are available in the literature relating to direct bonding to first molars, the results obtained in this study for the other teeth compare favourably with data previously published by other authors after trials using other types of cement

Congenital eunuchism and favorinus

Ancient Hebrew literature as well as the New Testament differentiate between castrated eunuchs and congenital eunuchs. Congenital eunuchism is very rare today, and assuming that this was also the case in classical times, we investigated possible reasons why congenital eunuchs feature prominently. We discuss the probability that the concept `congenital eunuchism' might in ancient times have included effeminate men who, according to cultural views on `maleness' and androgyny, were almost equated with eunuchs. The causes of congenital hypogonadism are reviewed in order to attempt clarification of the condition of Favorinus, a congenital eunuch in the second century AD. We suggest that although he might have been a true hermaphrodite, as suggested by some s, it is more likely that he had one of the following conditions: functional prepubertal castrate syndrome, testicular gonadotrophin insensitivity, selective gonadotrophin deficiency or Reifenstein's syndrome.

The impact of competition vs cooperation between subsidiaries within a multinational corporation

This research seeks to determine the impact of headquarter control, rent- seeking behaviour, inter-subsidiary cooperation and competition on multination corporation (MNC) business performance. The research presents a framework for MNCs to structure its headquarter-subsidiary and subsidiary-subsidiary relationships to best support its global profit and shareholder value maximisation goal. The study used a quantitative research design to survey all MNCs operating within South Africa with headquarters in Europe, Japan or the United States of America. A survey (on-line questionnaire) measured the perceived level of subsidiary autonomy (headquarter control), rent-seeking behaviour, inter- subsidiary cooperation, inter-subsidiary competition and MNC performance (increase in domestic market share) within each subsidiary. An objective measure of MNC performance (global return on shareholder funds) was also included to confirm the validity of the research findings. The study used a multiple linear regression model to analyse the data. The research study found that a business strategy that promotes high levels of both inter-subsidiary cooperation and competition will maximise business performance. The study also confirmed that headquarter control constrains rent-seeking behaviour, whilst rent-seeking behaviour will harm MNC performance. The study, however, found that high levels of headquarter control has a net negative impact on global MNC performance.Dissertation (MBA)--University of Pretoria, 2010.Gordon Institute of Business Science (GIBS)unrestricte
