- Description: Detecting and investigating intrusive Internet activity is an ever-present challenge for network administrators and security researchers. Network monitoring can generate large, unmanageable amounts of log data, which further complicates distinguishing between illegitimate and legiti-mate traffic. Considering the above issue, this article has two aims. First, it describes an investigative methodology for network monitoring and traffic review; and second, it discusses results from applying this method. The method entails a combination of network telescope traffic capture and visualisation. Observing traffic from the perspective of a dedicated sensor network reduces the volume of data and alleviates the concern of confusing malicious traffic with legitimate traffic. Com-plimenting this, visual analysis facilitates the rapid review and correla-tion of events, thereby utilizing human intelligence in the identification of scanning patterns. To demonstrate the proposed method, several months of network telescope traffic is captured and analysed with a tai-lor made 3D scatter-plot visualisation. As the results show, the visuali-sation saliently conveys anomalous patterns, and further analysis re-veals that these patterns are indicative of covert network probing activi-ty. By incorporating visual analysis with traditional approaches, such as textual log review and the use of an intrusion detection system, this re-search contributes improved insight into network scanning incidents.

Work methods and procedures for plague surveillance and control in South Africa

- Description: Plague is a classic zoonosis caused by the bacterium Yersinia pestis and is subject to the International Health Regulations, 1969. In the last two millennia, plague has become widespread, with three pandemics occurring in the 6th, 14th and 20th centuries. Currently, plague outbreaks and epidemics still occur worldwide. This study attempts to develop formal work methods and procedures for plague surveillance and control by environmental health practitioners as a strategy to ensure that field data can be integrated within the municipal, provincial and national spheres of government. A qualitative, explorative, descriptive, inductive and deductive research design was followed. A documentary research approach was employed as the primary method of data collection. To obtain additional information, both semi-structured personal interviews and physical observations during plague surveillance were adopted by the researcher. The organisational structure of the health care system in South Africa was analysed to identify and explain the role and functions of relevant decision-makers related to the surveillance and control of plague within the different spheres of government. Legislative measures regarding plague surveillance and control were also presented. As a prerequisite for the development of work methods and procedures for plague surveillance and control, the epidemiology of plague was discussed with emphasis on the distribution and characteristics of the disease in South Africa. Important rodent reservoirs and flea vectors of plague in South Africa were identified. Clinical manifestations, diagnosis and treatment of plague were described and discussed. Within this qualitative study an attempt has been made to develop work methods (xiii) and procedures for plague surveillance and control in South Africa. Relevant field data forms to be used during plague surveillance and control strategies were also developed. Recommendations emanating from the study can be found in the final chapter.

- Description: When Grocott's Mail in Grahamstown wanted to use the Hector Pieterson photograph for the front cover of a Youth Day supplement celebrating the courage of the Soweto students of 1976, they decided to go the official route by contacting the photographer's agent and paying for the picture. They were told a single use would cost them thousands of rands. Obviously an impossibility for a small-town, community newspaper.

Zambia African Media Development Initiative (AMDI) research report

- Description: This report is one of 18 produced as part of the African Media Development Initiative Research Project, completed in 2006. Firstly, the study outlines the major media development initiatives that have taken place in the Zambian media and communication landscape since 2000. Secondly, it analyses how key actors view these initiatives, in the light of wider media development programmes unfolding on the African continent. Thirdly, it gives a case study of one particularly insightful media development activity in the country. On the whole, the study concludes that the radio sector has grown since 2000. Television has received little investment because the state has more control over this sector. The past five years have seen a growth in better-coordinated media development initiatives. The content of the media has itself become diversified, but there is still a prepoderance of urban-based, elite voices.

‘Exploring the practical adequacy of the human rights, social justice, inclusivity and healthy environment policy discourse in South Africa’s National Curriculum Statement’

- Description: This article examines the practical adequacy of the recent defining of a normative framework for the South African National Curriculum Statement that focuses on the relationship between human rights, social justice and a healthy environment. This politically framed and socially critical normative framework has developed in response to socio-political and socio-ecological histories in postapartheid curriculum transformation processes. The article critically considers the process of working with a normative framework in the defining of environmental education teaching and learning interactions, and seeks not only to explore the policy discourse critically, but also to explore what it is about the world that makes it work in different ways. Drawing on Sayer’s perspectives on the possibilities of enabling ‘situated universalism’ as a form of normative theory, and case-based data from a teacher professional development programme in the Makana District (where the authors live and work), the article probes the relationship between the establishment of a ‘universalising’ normative framework to guide national curriculum, and situated engagements with this framework in/as democratic process. In this process it questions whether educators should adopt the ‘norms’ as presented by society and simply universalize and implement them as prescribed by curriculum statements, or whether educators should adopt the strategies of postmodernists and reduce normative frameworks to relations of power situated in particular contexts.
