a Digital Forensics Institute in Malaysia (DFIM) is proposed
Remote sensing of forage nutrients: Combining ecological and spectral absorption feature data
No full textForage quality in grassland-savanna ecosystems support high biomass of both wild ungulates and domestic
livestock. Forage quality is however variable in both space and time. In this study findings from
ecological and laboratory studies, focused on assessing forage quality, are combined to evaluate the
feasibility of a remote sensing approach for predicting the spatial and temporal variations in forage quality.
Spatially available ecological findings (ancillary data), and physically linked spectral data (absorption
data) are evaluated in this study and combined to create models which predict forage quality (nitrogen,
phosphorus and fibre concentrations) of grasses collected in the Kruger National Park, South Africa, and
analysed in both dry and wet seasons. Models were developed using best subsets regression modelling.
Ancillary data alone, could predict forage components, with a higher goodness of fit and predictive capability,
than absorption data (Ancillary: R2
adj ¼ 0:42—0:74 compared with absorption: R2
adj ¼ 0:11—0:51,
and lower RMSE values for each nutrient produced by the ancillary models). Plant species and soil classes
were found to be ecological variables most frequently included in prediction models of ancillary data.
Models in which both ancillary and absorption variables were included, had the highest predictive capabilities( R2adj ¼ 0:49—0:74 and lowest RMSE values) compared to models where data sources were
derived from only one of the two groups. This research provides an important step in the process of creating biochemical models for mapping forage nutrients in savanna systems that can be generalised seasonally over large areas
Voice Over IP and forensics: A review of recent Australian work. Paper presented at the 1st International Conference on Digital Forensics and Investigation (ICDFI), September 21-23, 2012, Beijing, China.
No full textInternational Conference on Digital Forensics and Investigation (ICDFI) (1st : 2012 September 21-23 : Beijing, China)The popularity of Voice over the Internet Protocol (VoIP) for providing voice communication over IP networks such as the Internet has resulted in VoIP becoming a global telephony service. VoIP applications convert analogue voice signals into a digital format, which is then encapsulated into IP packets for transmission over the Internet. Our research has examined both the security and privacy implications of widespread adoption of VoIP for personal and business telecommunications and also the use of VoIP calls by criminals, as many implementations of VoIP may also use strong encryption to secure both the voice payload as well as to control messages. We have also considered the implication of recovering electronic evidence and information from VoIP since conventional methods of eavesdropping and wire-tapping do not apply to VoIP calls.
This paper provides an overview of the development of investigative processes and forensic tools to enable law enforcement to engage the digital forensic process in a VoIP environmen
A non-monotonic convergence analysis of population clusters of random numbers.
No full textThe standard deviation of a population (of size N ) is a measure of the spread of the population observations about the mean. A population may be clustered and the standard deviation of each cluster calculated. This paper looked at how the mean of the standard deviations of the clusters of a population of random numbers relate to the standard deviation of the population as the size of the clusters increased. We assumed that all clusters have the same size
Student success and dropout rates at the NUST.
No full textIn developing the Education and Training Sector Improvement Programme (ETSIP), the government of Namibia had indicated that one of its key goals was to strengthen and improve quality, effectiveness and efficiency in higher education. This descriptive, non-intervental study was undertaken in response to the changing policy environment, mainly to determine the teaching and learning performance of the NUST in terms of student enrolment, success and dropout rates for a fifteen year (1996 –2010) period. The key findings of the study are that between 2006 and 2010 student success rates declined (68 to 59%), and over the same period student dropout rates also decreased (23 to19%). Whilst reasons for the decrease in dropout rates were not easily identifiable, reasons for decrease in success rates could be linked to changes in the ratios of student, programme and course to academic staff
Systematic corruption and corrective change management strategies: A study of the co-producers of systematic corruption and its negative impact on socio-economic development
No full textThesis (PhD)--Stellenbosch University, 2012.The focus of the study is the socio-economic impact of systemically corrupt institutions on developing countries. The unit of analysis is systemic corruption. The study seeks to make a contribution towards the understanding of, and insight into, corruption in private and public institutions. Corruption is a subsystem of the social system that is embedded in the economy, politics, science and technology, ethics, and aesthetics. Systemic corruption is not only an impairment of integrity, virtue and moral principle(s), but a departure from the original purpose, processes, structure, governance and context of systems created with the intention to be pure and correct and to enable development. Systemic corruption is destructive for development. Corruption is a social pathology. As a systemic problem situation, corruption does not have root causes, but co-producers. These co-producers are obstructions to first-order-development of an institution and society. If these first-order-co-producers interact, e.g. when marginal groups are powerless and do not have any hope of being accommodated in formal society (that is synonymous with a better life) the impact thereof co-produces second-order-problems, e.g. alienation and polarisation. Alienated people organise themselves and for survival create their own values and culture that contradict those of formal society. For example, organised criminal groups are not accommodated within the formal structures of society; they are labelled, feared and detested. Marginal groups use the negative impact they experience during alienation and polarisation, i.e. absolute, relative, and total deprivation from goods, services, knowledge, influence, norms and identity, to justify their corrupt practices. Corruption cannot be solved with linear solutions, but should be addressed by a systemic approach, e.g. system dynamics, soft - and complex systems. This approach aims to change the „culture of corruption‟ by changing the environment that contributes to corruption, i.e. by eliminating programmes that co-produce corruption, by developing moral and transformational leaders and role models, and by developing innovative, transparent and accountable institutions. This dissertation is primarily a hermeneutic study. Exploratory research provided insight into and comprehension of the co-producers and impacts of corruption. Although a substantial volume of literature on corruption exists, very few employ a systemic framework that provides a holistic understanding of corruption and its relationship with other variables within the context of the developing world. The relationship with these variables is important to gain an understanding of the complexity of corruption. Corruption can be a concept, a condition, a manifestation, and a co-producer that contribute towards poverty and under-development. Corruption can also be a co-impact on poverty and under-development. The multidimensional dynamics of corruption to take on various „masks‟ make it an elusive phenomenon. As a complex subsystem, corruption takes on a life of its own that is self sustaining - corruption strengthens corruption. Corruption‟s co-producers, various manifestations and devastating impacts can at best be understood in terms of contextualising these from a systemic and complex system perspective. The dissertation offers a conceptual framework for identifying systemically corrupt institutions. Strategies were developed for change management to transform such institutions to international best practices. These strategies are based on the principles of good governance, institutional capital and trust, quality personnel, a culture of discipline, and sustainability. The concept of „quality‟ is central to the creation of social/institutional capital, an integrated institution and also in the control and management of these strategies. Strategies and processes were developed for a complete institutional change and transformation, by creating institutions that enhance participation, parity, organisation, adaptation and innovation. These strategies were developed by integration, e.g. developing social capital; differentiation, e.g. application of specialised knowledge and skills about procurement; coordination; and control of systemic corruption. For every level of differentiation, a minimum required level of integration is required. Therefore, all strategies „balance‟ opposing developmental aspirations. A discussion of developing countries‟ corruption problem situations, based on examples of real incidents of corruption, illustrates what can be done if reform of people and transformation of systems are applied systemically. Corrective change management strategies were tailored for suiting a unique context, governance, structure, purpose and processes. The discussion assessed the key drivers and key uncertainties with possible directions of how these alternatives can unfold in terms of the Namibian corruption problem situation. Leverage points describe how to implement the most effective containment strategies with the best outcome in the shortest time. Containing strategies include hard, formal and tactical-operational strategies. Dissolving strategies focus on soft, informal and long-term sustainable transformation
Economic growth and tax structure in Zimbabwe: 1984–2009
No full textWe examine the tax-growth nexus in Zimbabwe using parametric
and non-parametric analysis. We use a two-stage estimation procedure that first
generates efficiency scores for the country using a Data Envelopment
Approach. We use the efficiency scores in the second stage to normalise
growth to get a proxy for potential economic growth. Using this potential
growth we run a translog model that allows computation of time-varying
elasticities of growth to changes in tax policy. The translog model results we
got indicate that economic growth is inelastic to tax structure in Zimbabwe.
As such, we recommend policies that rely on non-tax stimuli to the economy
to buttress growth. We find that the most inefficient years were those
punctuated with bad economic governance and droughts
Namibian policy perspectives on solar energy.
No full textBook Chapter by Kudakwashe Ndhluluka of the Renewable Energy and Energy Efficiency Institute (REEEI), NUST.Namibia’s policy priorities on energy and its development are based on the White
Paper on Energy Policy of 1998. The White Paper sets six strategic goals:
1. Effective governance
2. Security of supply
3. Social upliftment
4. Investment and growth
5. Economic competitiveness and efficiency
6. Sustainability.
The White Paper also recognises the importance of renewable energy and energy
efficiency in Namibia’s socio-economic development as providing ‘sustainability’
and ‘security of supply’ by virtue of diversification and the use of locally
available resources.
Since the launch of the Policy Paper in 1998, a number of initiatives and
renewable energy programmes have been set in motion in partnership with various
local and international groups.
The country, like most developing countries, faces immense challenges in
providing basic infrastructure such as electricity and energy services, in general,
to previously disadvantaged communities. Many of these communities reside
in communal areas, and they are far too displaced for grid electrification to be
deployed cost-effectively.
This paper analyses some of these initiatives, especially those that are focussd
on solar energy. Some of the key questions to be addressed in the paper
are as listed below.
1. What key strategic initiatives and their specific objectives have been implemented
so far in the fulfillment of the Policy Paper?
2. How effective and efficient have these initiatives been?
3. What is the level of wider stakeholder involvement in the initiatives? 4. How is financing and quality assurance of solar energy technologies being
addressed through the policy framework?
5. What are the inadequacies in the Policy Paper to address the current and
future challenges in the solar energy sector
Urban lives and the complexities of change: Cultural transformation for survival in contemporary Zimbabwean fiction.
No full textThis paper explores the literary representation of the complex, heterogeneous and constantly shifting socio-cultural dynamics of Zimbabwean city-making and human survival today. It's raison d'etre is premised on the desire to explicate through nuanced paradigms, a study of African culture using three short stories by Shimmer Chonodya's "Last laugh", Erasmus Chinyani's "A land of starving millionaires" and Julius Chingono's "Minister without Portfolio". Attention is focussed on perspectives on urbanity and how creative cultural expressions (fiction) offer critical discourse on human survival during periods of tempestuous changes. The result is an emphasis on African city-making through fluid and rapidly changing cultural structures and the ability of the urbanites to adjust, negotiate and innovate. Critical is a literary analysis of their espousal and reformulation of the political, moral and socio-economic terrain thereby fostering a distinct culture of "city dwellership". As a result this multiplex perspective of the city rests on a non-essentialist conception of urbanity and the short stories demonstrate the artistic expressions of how the people have not only found effective ways of pursuing their livelihoods but also how to interpret and reformulate these pronouncements in harsh and tyrannical contexts
