Learning as knowledge networking : conceptual foundations for revised uses of the internet in higher education

This paper argues that the inherent characteristics of knowledge work, when combined with the operation of the Internet in contemporary society, produce a change in the dominant paradigm of what constitutes knowledge work. Since learning is a form of knowledge work, therefore this change will affect university education. The paper further argues that, because of the way in which online learning initially developed in universities, in most cases, the current approach to the Internet and higher education does not account for the changed conditions of knowledge in a network society. It concludes that new directions are needed which will allow us to make technology and pedagogy choices for future education better suited to a network society.

The impact of past direct-personal traumatic events on 12-month outcome in first episode psychotic mania: trauma and early psychotic mania

Past traumatic events have been associated with poorer clinical outcomes in people with bipolar disorder. However, the impact of these events in the early stages of the illness remains unclear. The aim of this study was to investigate whether prior traumatic events were related to poorer outcomes 12 months following a first episode of psychotic mania.

Uses of management control and performance measurement systems by Deans and Heads in Australian universities: their effects on research, teaching and networking capabilities

Invoking a resource-based view (RBV), this study investigates relationships between management control systems (MCSs) use, including information use from performance measurement systems (PMSs), and organisational capabilities in the context of academic units of Australian universities. Increased competition and attention to distinctive capabilities amongst universities, particularly at their strategic operating unit level of a Faculty1 or School2, provides the setting for application of this theoretic perspective. Based on a questionnaire survey of all Faculty Deans and Heads of Schools in all 39 universities in Australia, evidence is provided on relationships between diagnostic and interactive use of MCSs, attention given to imposed and discretionary types of PMS information, the strength of capabilities of the academic unit and, in turn, overall performance of the academic unit. Highlights of findings are that Heads/Deans conceived capabilities of their unit in functional dimensions, not in generic dimensions as found in prior literature; interactive MCS use and imposed performance measures, respectively, direct relate to several types of capabilities and indirectly to performance of the academic unit, but diagnostic MCS use does not. The findings have practical implications for styles of control systems use and performance information use by management in universities.

Uses of the sampur in the halus (Refined) style of Yogyakarta court dance

In this essay I discuss how a familiar costume element in Javanese court dance, a long piece of patterned cloth known as the sampur, functions poetically through the ways it is used by the dancer. I elaborate on eight categories of use of the sampur, primarily from the point of view of a Western dancer first encountering the techniques of working with the scarf. I draw on scholars and other commentators to discuss the many dimensions of meaning embodied by these uses. The sampur emerges as a dance element rich in virtuosic potential and nuance, and resonant with numerous dimensions of cultural values.

Pooled panel unit root tests and the effect of past initialization

This paper analyzes the role of initialization when testing for a unit root in panel data, an issue that has received surprisingly little attention in the literature. In fact, most studies assume that the initial value is either zero or bounded. As a response to this, the current paper considers a model in which the initialization is in the past, which is shown to have several distinctive features that makes it attractive, even in comparison to the common time series practice of making the initial value a draw from its unconditional distribution under the stationary alternative. The results have implications not only for theory, but also for applied work. In particular, and in contrast to the time series case, in panels the effect of the initialization need not be negative but can actually lead to improved test performance.

Are the profiles of past-year internet gamblers generalizable to regular internet gamblers?

 Research generally classifies internet gamblers as those who have gambled online at least once in the previous year. This classification system has been criticised on the grounds that it fails to consider the frequency of internet gambling. This study aimed to contrast the demographic, gambling, and psychosocial profiles of regular internet gamblers (at least monthly in the previous year) with those of past-year internet gamblers. Computer-assisted telephone interviews were conducted with 4303 adult respondents from Tasmania, Australia. The findings revealed that 3.3% were past-year internet gamblers and 2.1% were regular internet gamblers. Both past-year and regular internet gambling were significantly associated with several variables (younger age, dependent children, paid employment, higher annual income, higher gambling frequency and expenditure, younger age of first gambling, challenge and positive feelings gambling motives, and positive reinforcement gambling triggers). However, several variables were significantly associated only with past-year internet gambling (male gender, living with partner, number of gambling activities, regulate internal state gambling motives, hazardous alcohol use, cannabis use, and other illicit drug use) or regular internet gambling (higher education). Only gambling for positive feelings was a significant independent predictor of both past-year and regular internet gambling. These findings suggest that the classification of past-year internet gambling that is normally employed in research produces profiles that are not fully generalizable to regular internet gamblers.

Belonging and the uses of difference: young people in Australian urban multiculture

This paper examines how young people of migrant background in Australia make meaning of cultural, ethnic and racial difference to work out belonging in times of super-diversity. It asks what functions difference still has for a generation growing up within conditions of proliferating diversity that demand and accommodate competing constructions of cultural identities. It suggests that young people's narratives about difference depend on the space of belonging, and explores how young people use difference differently depending on whether they are articulating membership in the local community, the nation or youth culture.

Risk and benefit perceptions: Resistance, adoption and uses of ICT among the Italian elderly

This paper presents the main results of a national survey on active aging, with a sample of 900 Italians between 65 and 74 years of age. The research attempted to understand the role of ICT in the daily life of the elderly, in the attempt to answer the following questions: (1) What are the differences between the connected and not connected elderly? (2) What are the perceived risks and opportunities identified by older ICT users? This paper investigates the complex relationship between the elderly and technology, going beyond both deterministic approaches and optimistic analyses of the use (and non-use) of the Internet among elderly Italians.

Ties to the past in organization research : a comparative analysis of retrospective methods

This paper addresses a traditionally neglected area of management and organizational studies—retrospective research. It identifies, describes and analyses four positions on retrospective research: Controlling the Past, in which attempts are made to maximize accurate recall or to reveal potential sources of error or bias; Interpreting the Past, in which understanding of the present is informed by the construction of past reality; Co-opting the Past, in which causal explanations link the past and the present; and Representing the Past, which involves the problematization of time and research on time. These positions are compared in terms of, for example, method, philosophy, examplars and potential contribution. Finally, implications are drawn for the practice of retrospective research in management and organization studies.

Taking environmental water requirements and climate change into account in the designation and management of protected areas for floodplain ecosystems

In 2005, the Victorian government asked the Victorian Environmental Assessment Council (VEAC) to 1) identify and evaluate the extent, condition, values, management, resources and uses of riverine red gum forests and associated fauna, wetlands, floodplain ecosystems and vegetation communities in northern Victoria; and 2) make recommendations relating to the conservation, protection and ecological sustainable use of public land. The design of a comprehensive, adequate and representative (CAR) reserve system was a key part of the recommendations made by VEAC. In order to assist in the decision-making for environmental water allocation for protected areas and other public land, a process for identifying flood-dependent natural values on the Victorian floodplains of the River Murray and its tributaries was developed.

Although some areas such as the Barmah forest are very well known, there have been few comprehensive inventories of important natural values along the Murray floodplains. For this project, VEAC sought out and compiled data on flood requirements (natural flood frequency, critical interval between floods, minimum duration of floods) for all flood-dependent ecological vegetation classes (EVCs) and threatened species along the Goulburn, Ovens, King and Murray Rivers in Victoria. The project did not include the Kerang Lakes and floodplains of the Avoca, Loddon and Campaspe Rivers. 186 threatened species and 110 EVCs (covering 224,247 ha) were identified as flood-dependent and therefore at risk from insufficient flooding.

Past environmental water allocations have targeted a variety of different natural assets (e.g. stressed red gum trees, colonial nesting waterbirds, various fish species), but consideration of the water requirements of the full suite of floodplain ecosystems and significant species has been limited. By considering the water requirements of the full range of natural assets, the effectiveness of water delivery for biodiversity can be maximised. This approach highlights the species and ecosystems most in need of water and builds on the icon sites approach to view the Murray floodplains as an interconnected system. This project also identified for the first time the flood-frequency and duration requirements for the full suite of floodplain ecosystems and significant species.

This project is the most comprehensive identification of water requirements for natural values on the floodplain to date, and is able to be used immediately to guide prioritisation of environmental watering. As more information on floodplain EVCs and species becomes available, the water requirements and distribution of values can be refined by ecologists and land and water managers. That is, the project is intended as the start of an adaptive process allowing for the incorporation of monitoring and feedback over time. The project makes it possible to transparently and easily communicate the extent to which manipulated or natural flows benefit various natural values. Quantitative and visual outputs such as maps will enable environmental managers and the public to easily see which values do and do not receive water (see http://www.veac.vic.gov.au/riverredgumfinal.htm for further details).

Characterization and prediction of issue-related risks in software projects

Identifying risks relevant to a software project and planning measures to deal with them are critical to the success of the project. Current practices in risk assessment mostly rely on high-level, generic guidance or the subjective judgements of experts. In this paper, we propose a novel approach to risk assessment using historical data associated with a software project. Specifically, our approach identifies patterns of past events that caused project delays, and uses this knowledge to identify risks in the current state of the project. A set of risk factors characterizing “risky” software tasks (in the form of issues) were extracted from five open source projects: Apache, Duraspace, JBoss, Moodle, and Spring. In addition, we performed feature selection using a sparse logistic regression model to select risk factors with good discriminative power. Based on these risk factors, we built predictive models to predict if an issue will cause a project delay. Our predictive models are able to predict both the risk impact (i.e. the extend of the delay) and the likelihood of a risk occurring. The evaluation results demonstrate the effectiveness of our predictive models, achieving on average 48%-81% precision, 23%-90% recall, 29%-71% F-measure, and 70%-92% Area Under the ROC Curve. Our predictive models also have low error rates: 0.39-0.75 for Macro-averaged Mean Cost-Error and 0.7-1.2 for Macro-averaged Mean Absolute Error.

The use of injury surveillance databases to identify emerging injury hazards

Among the many valuable uses of injury surveillance is the potential to alert health authorities and societies in general to emerging injury trends, facilitating earlier development of prevention measures. Other than road safety, to date, few attempts to forecast injury data have been made, although forecasts have been made of other public health issues. This may in part be due to the complex pattern of variance displayed by injury data. The profile of many injury types displays seasonality and diurnal variance, as well as stochastic variance. The authors undertook development of a simple model to forecast injury into the near term. In recognition of the large numbers of possible predictions, the variable nature of injury profiles and the diversity of dependent variables, it became apparent that manual forecasting was impractical. Therefore, it was decided to evaluate a commercially available forecasting software package for prediction accuracy against actual data for a set of predictions. Injury data for a 4-year period (1996 to 1999) were extracted from the Victorian Emergency Minimum Dataset and were used to develop forecasts for the year 2000, for which data was also held. The forecasts for 2000 were compared to the actual data for 2000 by independent t-tests, and the standard errors of the predictions were modelled by stepwise hierarchical multiple regression using the independent variables of the standard deviation, seasonality, mean monthly frequency and slope of the base data (R = 0.93, R² = 0.86, F_{(3, 27)} = 55.2, p < 0.0001). Significant contributions to the model included the SD (β = 1.60, p < 0.001), mean monthly frequency (β =  - 0.72, p < 0.002), and the seasonality of the data (β = 0.16, p < 0.02). It was concluded that injury data could be reliably forecast and that commercial software was adequate for the task. Variance in the data was found to be the most important determinant of prediction accuracy. Importantly, automated forecasting may provide a vehicle for identifying emerging trends.

Behavioural characteristics of rapists

A substantial proportion of past research on rapists has focused on their motives. This paper reports on two studies that investigated the behavioural characteristics of rapists. The first study gathered behavioural data from police rape files to determine the types of behaviours exhibited by 130 men charged with rape. The second study was designed to validate the behavioural clusters found in study 1, using the transcripts of court cases from a sample of 50 accused rapists. The results demonstrated a high level of consistency in the behaviours of the accused rapists in the two studies. Rapists were most frequently a stranger, the rape occurred frequently in the victim's home, and the rapist used a range of different ways to communicate verbally with his victim. Five behavioural themes were identified in both studies: vaginal, kissing/fondling, oral, anal and brutal/physical themes. This analysis of the behavioural aspects of rape provides an understanding of the types of behaviours exhibited by men who reach the stage of court proceedings for the crime of rape. The difference between the current behavioural profile and that reported by members of the general community who have experienced rape is discussed.
