Ethical Dimension of Time in Plato’s Apology of Socrates

The aim of the present article is to analyse the Apology in its aspect of time. When defending himself against the charges, Socrates appeals to the past, the present and the future. Furthermore, the philosopher stresses the meaning of the duration of time. Thus, the seems to suggest that all really important activities demand a long time to benefit, since they are almost invariably connected with greater efforts. While the dialogue proves thereby to be an ethical one, the various time expressions also gain an ethical dimension.

Australian professional standards for teachers and the ethical dimension of policies

A critical and interpretative investigation of the ethical dimension of policies about school digital technologies

This thesis examines digital technologies policies designed for Australian schools and the ways they are understood and interpreted by students, school staff, teachers, principals and policy writers. This study explores the ways these research participant groups interpret and understand the ‘ethical dimension’ of schools’ digital technologies policies for teaching and learning. In this thesis the ethical dimension is considered to be a dynamic concept which encompasses various elements including; decisions, actions, values, issues, debates, education, discourses, and notions of right and wrong, in relation to ethics and uses of digital technologies in schools. In this study policy is taken to mean not only written texts but discursive processes, policy documents including national declarations, strategic plans and ‘acceptable use’ policies to guide the use of digital technologies in schools. The research is situated in the context of changes that have occurred in Australia and internationally over the last decade that have seen a greater focus on the access to and use of digital technologies in schools. In Australian school education, the attention placed on digital technologies in schools has seen the release of policies at the national, state, territory, education office and school levels, to guide their use. Prominent among these policies has been the Digital Education Revolution policy, launched in 2007 and concluded in 2013. This research aims to answers the question: What does an investigation reveal about understandings of the ethical dimension of digital technologies policies and their implementation in school education? The objective of this research is to examine the ethical dimension of digital technologies policies and to interpret and understand the responses of the research participants to the issues, silences, discourses and language, which characterise this dimension. In doing so, it is intended that the research can allow the participants to have a voice that, may be different to the official discourses located in digital technologies policies. The thesis takes a critical and interpretative approach to policies and examines the role of digital technologies policies as discourse. Interpretative theory is utilised as it provides a conceptual lens from which to interpret different perspectives and the implications of these in the construction of meaning in relation to schools’ digital technologies policies. Critical theory is used in tandem with interpretative theory as it represents a conceptual basis from which to critique and question underlying assumptions and discourses that are associated with the ethical dimension of schools’ digital technologies policies. The research methods used are semi-structured interviews and policy document analysis. Policies from the national, state, territory, education office and school level were analysed and contribute to understanding the way the ethical dimension of digital technologies policies is represented as a discourse. Students, school staff, teachers, principals and policy writers participated in research interviews and their views and perspectives were canvassed in relation to the ethical use of digital technologies and the policies that are designed to regulate their use. The thesis presents an argument that the ethical dimension of schools’ digital technologies policies and use is an under-researched area, and there are gaps in understanding and knowledge in the literature which remain to be addressed. It is envisaged that the thesis can make a meaningful contribution to understand the ways in which schools’ digital technologies policies are understood in school contexts. It is also envisaged that the findings from the research can inform policy development by analysing the voices and views of those in schools. The findings of the policy analysis revealed that there is little attention given to the ethical dimension in digital technologies at the national level. A discourse of compliance and control pervades digital technologies policies from the state, education office and school levels, which reduces ethical considerations to technical, legal and regulatory requirements. The discourse is largely instrumentalist and neglects the educative dimension of digital technologies which has the capacity to engender their ethical use. The findings from the interview conversations revealed that students, school staff and teachers perceive digital technologies policies to be difficult to understand, and not relevant to their situation and needs. They also expressed a desire to have greater consultation and participation in the formation and enactment of digital technologies policies, and they believe they are marginalised from these processes in their schools. Arising from the analysis of the policies and interview conversations, an argument is presented that in the light of the prominent role played by digital technologies and their potential for enhancing all aspects of school education, more research is required to provide a more holistic and richer understanding of the policies that are constructed to control and mediate their use.

Truth - the essential dimension of ethics in scholarship, teaching, learning and research

The introduction of metrics, league tables, performance targets, research assessment exercises and a range of other pressures placed by society, funding bodies and employers on scholars, teachers and students have resulted in diminished value being placed on the essential ethical criterion of truth. The impact of reduced valuation for truth has a huge impact on the standing of science and not least horticultural science in the eyes of the general public at a time when this should be a primary concern. This contribution discusses examples of the impact of diminished valuation of truth, the causes of this phenomenon, the results that come from this situation and remedies that are needed.

The ethical dimension f analyst's interventions facing institutional demands of CAPS

(The ethical dimension f analyst's interventions facing institutional demands of CAPS) Considering the complexities involved in setting up clinical work in the psychosocial field, analyst must question their own contributions toward improvements in this area. This issue is presented here as a considerable challenge, due to the limitations of psychoanalytic practice and, especially, the differences between conventional clinical practice and that carried out in institutional and political settings. From this perspective, we call attention to the notion of ethics as a differentiating and guiding concept for psychoanalytic practice in its contribution toward the treatment provided at CAPS.

The time dimension of neural network models

This review attempts to provide an insightful perspective on the role of time within neural network models and the use of neural networks for problems involving time. The most commonly used neural network models are defined and explained giving mention to important technical issues but avoiding great detail. The relationship between recurrent and feedforward networks is emphasised, along with the distinctions in their practical and theoretical abilities. Some practical examples are discussed to illustrate the major issues concerning the application of neural networks to data with various types of temporal structure, and finally some highlights of current research on the more difficult types of problems are presented.

The ethical predisposition of university students in Western Australia : 1997 vs 2007

A sample of 285 Western Australian university students was used to assess the prevailing attitudes regarding potential breaches of ethical conduct on the part of business practitioners and organisations. The authors developed an ethical profile for the 2007 sample based on 14 scenarios used in the questionnaire. This profile was then compared to the results from data collected in 1997 using similar sampling and the same survey instrument. The prevailing predisposition is best viewed as centrist in nature, with a move to a more ethical stance in the last 10 years.

Butterpaper, sweat & tears : the affective dimension of engaging students during the architectural critique

Considering how dominant a feature of architectural education the critique has been, and continues to be, little has been written about the affective dimension of engaging students during this key final stage of the design or documentation process. For most students, the critique is unlike any previous educational or life experience that they have ever confronted, and the abrupt change in the instructor’s role, from tutor to judge, can be disconcerting at a time when the student is feeling their most vulnerable. The fact that the period immediately leading up to the critique habitually entails not only a focused and sustained effort, but also sleepless nights of intensive work, further exacerbates this. The purpose of this paper is to recognise the affective phenomena influencing student engagement, during the critique. The participants of this research were second to fourth year architecture students at a major Australian university. Following the implementation of trials in alternative modes of critique in architectural design and technology studios, qualitative data was obtained from students, through questionnaires and interviews. Six indicators of engagement were investigated through this research: motivation and agency, transactional engagement with staff, transactional engagement with students, institutional support, active citizenship, and non-institutional support. This research confirms that affective phenomena play a significant role in the events of the critique; the relationship between instructor and student influences student engagement, as does the choreography and spatial planning of the critique environment; and these factors ultimately have an impact on the depth of student learning.

The neglected dimension of community liveability : impact on social connectedness and active ageing in higher density accommodation

Purpose This thesis is about liveability, place and ageing in the high density urban landscape of Brisbane, Australia. As with other major developed cities around the globe, Brisbane has adopted policies to increase urban residential densities to meet the main liveability and sustainability aim of decreasing car dependence and therefore pollution, as well as to minimise the loss of greenfield areas and habitats to developers. This objective hinges on urban neighbourhoods/communities being liveable places, which residents do not have to leave for everyday living. Community/neighbourhood liveability is an essential ingredient in healthy ageing in place and has a substantial impact upon the safety, independence and well-being of older adults. It is generally accepted that ageing in place is optimal for both older people and the state. The optimality of ageing in place generally assumes that there is a particular quality to environments or standard of liveability in which people successfully age in place. The aim of this thesis was to examine if there are particular environmental qualities or aspects of liveability that test optimality and to better understand the key liveability factors that contribute to successful ageing in place. Method A strength of this thesis is that it draws on two separate studies to address the research question of what makes high density liveable for older people. In Chapter 3, the two methods are identified and differentiated as Method 1 (used in Paper 1) and Method 2 (used in Papers 2, 3, 4 and 5). Method 1 involved qualitative interviews with 24 inner city high density Brisbane residents. The major strength of this thesis is the innovative methodology outlined in the thesis as Method 2. Method 2 involved a case study approach employing qualitative and quantitative methods. Qualitative data was collected using semi-structured, in-depth interviews and time-use diaries completed by participants during the week of tracking. The quantitative data was gathered using Global Positioning Systems for tracking and Geographical Information Systems for mapping and analysis of participants’ activities. The combination of quantitative and qualitative analysis captured both participants’ subjective perceptions of their neighbourhoods and their patterns of movement. This enhanced understanding of how neighbourhoods and communities function and of the various liveability dimensions that contribute to active ageing and ageing in place for older people living in high density environments. Both studies’ participants were inner-city high density residents of Brisbane. The study based on Method 1 drew on a wider age demographic than the study based on Method 2. Findings The five papers presented in this thesis by publication indicate a complex inter-relationship of the factors that make a place liveable. The first three papers identify what is comparable and different between the physical and social factors of high density communities/neighbourhoods. The last two papers explore relationships between social engagement and broader community variables such as infrastructure and the physical built environments that are risk or protective factors relevant to community liveability, active ageing and ageing in place in high density. The research highlights the importance of creating and/or maintaining a barrier-free environment and liveable community for ageing adults. Together, the papers promote liveability, social engagement and active ageing in high density neighbourhoods by identifying factors that constitute liveability and strategies that foster active ageing and ageing in place, social connections and well-being. Recommendations There is a strong need to offer more support for active ageing and ageing in place. While the data analyses of this research provide insight into the lived experience of high density residents, further research is warranted. Further qualitative and quantitative research is needed to explore in more depth, the urban experience and opinions of older people living in urban environments. In particular, more empirical research and theory-building is needed in order to expand understanding of the particular environmental qualities that enable successful ageing in place in our cities and to guide efforts aimed at meeting this objective. The results suggest that encouraging the presence of more inner city retail outlets, particularly services that are utilised frequently in people’s daily lives such as supermarkets, medical services and pharmacies, would potentially help ensure residents fully engage in their local community. The connectivity of streets, footpaths and their role in facilitating the reaching of destinations are well understood as an important dimension of liveability. To encourage uptake of sustainable transport, the built environment must provide easy, accessible connections between buildings, walkways, cycle paths and public transport nodes. Wider streets, given that they take more time to cross than narrow streets, tend to .compromise safety - especially for older people. Similarly, the width of footpaths, the level of buffering, the presence of trees, lighting, seating and design of and distance between pedestrian crossings significantly affects the pedestrian experience for older people and impacts upon their choice of transportation. High density neighbourhoods also require greater levels of street fixtures and furniture for everyday life to make places more useable and comfortable for regular use. The importance of making the public realm useful and habitable for older people cannot be over-emphasised. Originality/value While older people are attracted to high density settings, there has been little empirical evidence linking liveability satisfaction with older people’s use of urban neighbourhoods. The current study examined the relationships between community/neighbourhood liveability, place and ageing to better understand the implications for those adults who age in place. The five papers presented in this thesis add to the understanding of what high density liveable age-friendly communities/ neighbourhoods are and what makes them so for older Australians. Neighbourhood liveability for older people is about being able to age in place and remain active. Issues of ageing in Australia and other areas of the developed world will become more critical in the coming decades. Creating livable communities for all ages calls for partnerships across all levels of government agencies and among different sectors within communities. The increasing percentage of older people in the community will have increasing political influence and it will be a foolish government who ignores the needs of an older society.

The hardness of approximating the boxicity, cubicity and threshold dimension of a graph

A k-dimensional box is the Cartesian product R-1 X R-2 X ... X R-k where each R-i is a closed interval on the real line. The boxicity of a graph G, denoted as box(G), is the minimum integer k such that G can be represented as the intersection graph of a collection of k-dimensional boxes. A unit cube in k-dimensional space or a k-cube is defined as the Cartesian product R-1 X R-2 X ... X R-k where each R-i is a closed interval oil the real line of the form a(i), a(i) + 1]. The cubicity of G, denoted as cub(G), is the minimum integer k such that G can be represented as the intersection graph of a collection of k-cubes. The threshold dimension of a graph G(V, E) is the smallest integer k such that E can be covered by k threshold spanning subgraphs of G. In this paper we will show that there exists no polynomial-time algorithm for approximating the threshold dimension of a graph on n vertices with a factor of O(n(0.5-epsilon)) for any epsilon > 0 unless NP = ZPP. From this result we will show that there exists no polynomial-time algorithm for approximating the boxicity and the cubicity of a graph on n vertices with factor O(n(0.5-epsilon)) for any epsilon > 0 unless NP = ZPP. In fact all these hardness results hold even for a highly structured class of graphs, namely the split graphs. We will also show that it is NP-complete to determine whether a given split graph has boxicity at most 3. (C) 2010 Elsevier B.V. All rights reserved.

Computing Fractal Dimension of Signals using Multiresolution Box-counting Method

In this paper, we have developed a method to compute fractal dimension (FD) of discrete time signals, in the time domain, by modifying the box-counting method. The size of the box is dependent on the sampling frequency of the signal. The number of boxes required to completely cover the signal are obtained at multiple time resolutions. The time resolutions are made coarse by decimating the signal. The loglog plot of total number of boxes required to cover the curve versus size of the box used appears to be a straight line, whose slope is taken as an estimate of FD of the signal. The results are provided to demonstrate the performance of the proposed method using parametric fractal signals. The estimation accuracy of the method is compared with that of Katz, Sevcik, and Higuchi methods. In ddition, some properties of the FD are discussed.

From Beijing with love: The global dimension of Bertolucci’s The Last Emperor

Famous for being the first foreign feature film that obtained permission to shoot in the Forbidden City, The Last Emperor (1987) is also one of the most ambitious and expensive independent productions of its time, awarded four Golden Globes and nine Academy Awards, including Best Picture. In addition, The Last Emperor can be considered as one of the first attempts of cinematic collaboration between West and East, in a period of cultural and economic transformations witnessed by China. This article aims to offer an overview of the production history of The Last Emperor, focusing on the co-production collaborations and the outcomes of a western auteur’s gaze on Chinese history. Questions of Orientalism, travel narrative and critical reception are taken into account in order to engage with the transnational implications of Bertolucci’s film and the western fascination with China.
