Does democracy scale?: a fractal model for the role of interactive technologies in democratic policy processesGeiselhart, Karin, n/a January 1999 (has links)
The development of interactive communication technologies, such as email and the Internet,
has stimulated much discussion about their potential to assist in the renewal of democracy.
Globalisation, intimately connected with technological advance, has likewise led to
considerations of 'governance' that transcend the nation state. This thesis poses the general
question: Can the efficiencies and economies which drive commercial applications of
interactive technology be applied to democratic policy processes? What conditions will
facilitate this?
The perspective taken here views policy as a communication process between networks of
actors who seek to use resources and decisions to promote their value systems (Considine
1994). Democracy is also seen as a communication process, with a set of criteria which
ensure equal access to information and agenda setting among participants (Dahl 1989).
These definitions and criteria have been chosen for their generality. They apply at all levels
of analysis, and thus may be used for comparison across scales. These are aligned with
concepts from complexity theory as applied to human nonlinear systems and organisational
dynamics, drawing mostly on Kiel(1994) and Stacey (1996). The inherent unpredictability
of these systems and their capacity for complex learning and adaptive self-organisation
offers an alternative paradigm to linear, hierarchical management models.
A combination of literature analysis and case study evidence leads to three extensions of
complexity theory as applied to human systems: Firstly, interactive technology is proposed
as a technique for the potential re-pluralisation of democratic processes in complex human
systems. The possibility of adding many new non-elite voices, and of making these available
to all others, relates to both chaotic forms of self-organisation and the benefits of electronic
democracy. Secondly, evidence is presented for the existence of fractal, or self-similar
patterns in the ways information technology is applied at different levels of governance. It is
shown that instrumental approaches which emphasise efficiency dominate technology use at
the global, national and organisational levels, and these are interdependent. Alternative
patterns which encourage participation also exist at every level. Thirdly, it is argued that the
values of the dominant actors are the main determinants of whether interactive technologies
will be structured to favour democratic forms of communication at every level.
Three theory chapters in Part I develop these arguments by extensive reviews of relevant
literatures. On the global level, convergent media, telecommunications and technology
conglomerates underpin a global 'nervous system' which discourages government
intervention, promotes a global monoculture, inhibits pluralistic debate by minimising access
to alternative forms of information, and emphasises individualism and consumption. Within
nations, widespread uniformity of public sector reform is sympathetic and responsive to
these globalising pressures. Deregulation, privatisation, retreat from public broadcasting,
down-sizing and outsourcing have become standard approaches, and are reflected in
Australian information technology policy and programs. Several exceptions demonstrate
more participatory approaches. At the organisational level, instrumental approaches to
management and computerisation also prevail. In each case, a shift towards globalising
values corresponds to applications of information technology which dampen the complex
interactivity required for democratic policy processes.
Part II supplements this analysis with case study evidence. The organisational data were
collected primarily during a two year qualitative study of interactive technology use in the
Australian Department of Finance and Administration. The researcher found technology use
was inseparable from other change processes, and these were found to have strong elements
inhibiting participation in internal policy. An instrumental approach to interactive technology
use reinforced hierarchical decision processes.
Three minor case studies looked at an internal mailing list in a federal agency, a mostly
national list on Internet and telecommunications policy, and an experiment in electronic
democracy at the local level. These offered additional insights into the ways interactive
technologies can contribute to complex but adaptive policy processes, if normative
democratic values guide their design.
The researcher proposes a set of communication protocols for the use of interactive
technologies in democratic policy processes. These would enable the forms of
communication necessary to reinvigorate democracy in an information age. It is also argued
that these protocols, if applied at the organisational level, and particularly within the public
sector, could become part of a reaffirmation of industrial democracy. This is necessary to
ensure the integrity and accountability of the public sector, given the progressive
intermingling of these institutions with private enterprise. Additional suggestions are made
for research into government uses of information technology as an important focus for policy
analysts.

Determination of an ultimate pit limit utilising fractal modelling to optimise NPVYasrebi, Amir Bijan January 2014 (has links)
The speed and complexity of globalisation and reduction of natural resources on the one hand, and interests of large multinational corporations on the other, necessitates proper management of mineral resources and consumption. The need for scientific research and application of new methodologies and approaches to maximise Net Present Value (NPV) within mining operations is essential. In some cases, drill core logging in the field may result in an inadequate level of information and subsequent poor diagnosis of geological phenomenon which may undermine the delineation or separation of mineralised zones. This is because the interpretation of individual loggers is subjective. However, modelling based on logging data is absolutely essential to determine the architecture of an orebody including ore distribution and geomechanical features. For instance, ore grades, density and RQD values are not included in conventional geological models whilst variations in a mineral deposit are an obvious and salient feature. Given the problems mentioned above, a series of new mathematical methods have been developed, based on fractal modelling, which provide a more objective approach. These have been established and tested in a case study of the Kahang Cu-Mo porphyry deposit, central Iran. Recognition of different types of mineralised zone in an ore deposit is important for mine planning. As a result, it is felt that the most important outcome of this thesis is the development of an innovative approach to the delineation of major mineralised (supergene and hypogene) zones from ‘barren’ host rock. This is based on subsurface data and the utilisation of the Concentration-Volume (C-V) fractal model, proposed by Afzal et al. (2011), to optimise a Cu-Mo block model for better determination of an ultimate pit limit. Drawing on this, new approaches, referred to Density–Volume (D–V) and RQD-Volume (RQD-V) fractal modelling, have been developed and used to delineate rock characteristics in terms of density and RQD within the Kahang deposit (Yasrebi et al., 2013b; Yasrebi et al., 2014). From the results of this modelling, the density and RQD populations of rock types from the studied deposit showed a relationship between density and rock quality based on RQD values, which can be used to predict final pit slope. Finally, the study introduces a Present Value-Volume (PV-V) fractal model in order to identify an accurate excavation orientation with respect to economic principals and ore grades of all determined voxels within the obtained ultimate pit limit in order to achieve an earlier pay-back period.
