This study investigates Thayer's activation theory as applied to fear appeals in advertising in the context of drinking-and-driving advertising. Young adults aged 18-24 were exposed to television advertisements employing three different levels of fear appeal. The impact of fear aroused (in terms of two dimensions namely energy and tension) by the advertisement stimuli on attitude and behavioural intention, was measured. The results showed that, for English-speaking respondents, a tension threshold was exceeded, where tension suppressed energy levels. The major contribution of this study is that, when fear appeals are considered in advertising for a drinking-and-driving campaign, the language differences in a target audience could warrant different approaches that should be carefully considered to maximise its impact.

The different worlds of business and Information Technology (IT), and the necessity for their alignment to create business effectiveness and efficiency, are the topics of this study. Enterprise Architecture (EA) has been proposed as a tool to create business-IT alignment. Several EA models and frameworks have been proposed, each based on a different value-creation paradigm. Few case studies, however, demonstrate the integrated use of these models and frameworks.
This study addresses the need for a common reference for comparing alignment approaches in addressing business-IT alignment. More specifically, it analyses Enterprise Architecture (EA) frameworks and the components that are used to optimise business-IT alignment. Some common patterns are identified and re-packaged as part of a proposed business-IT alignment framework (BIAF). The conceptual BIAF components are used to demonstrate the interpretation of the framework for four prominent models : the Zachman Framework. the Open GroupArchitecture Framework (TOGAF), the Federal Enterprise Architecture (FEA), and the Gartner Enterprise Architecture Framework (GEAF).
The BIAF forms the foundation of the case-study approach to research in business-IT alignment in this study, and offers a framework for analysing business-IT alignment in a single organisation. The study also provides a common reference for cross-case business-IT alignment analyses for industry-related organisations.

Models that enable efficient time allocation can be used to assist managers in understanding how to enhance their general efficiency. There are, however, few models that focus on the output efficiency of the public sector. This study investigates the concept of output efficiency in the South African Air Quality Departments. The primary purpose of the study is to develop a model to predict the extent to which organisational efficiency can be explained by the percentage of time allocated to a range of management activities. In this study, the development of a model using the logistic regression technique is discussed. Data were collected for two financial years (2005/6 and 2006/7) from the Air Quality Officers in the national, provincial and local departments (n = 228). The logistic regression model that was fitted indicated that the proportion of time spent on knowledge-management activities contributes most to the likelihood of a department being efficient.
