Measuring quality of life in alcohol and other drug users - the need for improvement

Objective : The use of Quality of Life (QoL) -related measures in Alcohol and Other Drug-related research has increased dramatically over the past decade. However, there remains a great deal of confusion about which type of QoL measure is most valid, what each constrict actually measures and the ethicality of the process of QoL measurement and its subsequent transfer to monetary value. This is particularly important in regard to subsequent resource allocation on the basis of Quality Adjusted Life Years (QALYs). We aim to review the logic of current QoL -related measurement and determine the most conceptually valid way of measuring QoL.

Methods : This review considers some of the broad principles that concern quality of life assessment. These are discussed in relation to health-related quality of life (HRQoL) and the measurement of subjective well-being.

Results : We argue that there are serious logical and methodological issues concerning HRQoL measurement, to the extent that the instruments may not be regarded as valid measures of life quality as this term is generally understood.

Conclusions : It is recommended that HRQoL measurement be abandoned in favour of three separate forms of measurement as medical symptoms, subjective well-being and specific dimensions of psychological ill-being.

Metamorphosis of a gold town : Stawell 1900-1940 : a study in local history

Examines the experience of the Wimmera town of Stawell as being representative of the early settlements created by gold rushes, and then threatened with extinction as the industry declined. Attention is paid to the role of community in Stawell's struggle to survive in the period between Federation and the Second World War. Reviews the economic and social processes involved in the eventual recovery. Argues that the forces of Stawell's historical legacy can be detected in the town's reaction to adversity after the closure of the last major mine in 1920.

How fine the air

Collections of quiet and reflective images that seem to imply a narrative. Drummond explores the abandoned, the forgotten, the fleeting, the rundown andthe empty buildings, people or moments. Turning upside-down the conventional ideas of aesthetic value, Drummond finds beauty amidst rubbish, empty spaces and the ostensibly ugly or overlooked. These works involve an accumulation of evidence and signs of habitation and presense, the way we're living, ultimately creating some kind of rough portraiture.

An investigation of complex shapes during low pressure tube hydroforming

Hollow structures made of Advanced High Strength Steel (AHSS) are increasingly used in the automobile industry for crash and structural components. Generally high pressure hydroforming is used to form these tabular parts, which is a costly manufacturing process due to the high pressure equipment and large tonnage presses required. A new process termed low pressure hydroforming, where a pressurized tube is crushed between two dies, represents a more cost effective alternative due to the lower pressures and die closing forces required.

In this study the low pressure tube hydroforming of one simple and two different complex hollow shapes is investigated. The complexities of the pat1S compared to simple shapes are critically studied and the die filling conditions are investigated and discussed. FUl1hennore the thickness distributions over the circumference of the part during forming are analyzed.

A new approach to determining environmental flow requirements : sustaining the natural values of floodplains of the southern Murray-Darling Basin

Large overbank flood events play an important role in maintaining largescale ecological processes and connectivity along and across the floodplains and between the rivers and their floodplains in the southern Murray-Darling Basin. However, the regulation of rivers means that extensive overbank flooding can only occur in the rare circumstance of extreme flood events. Recent environmental water allocations have focussed on the largest floodplain blocks (‘icon’ sites) and a small set of specific values (e.g. colonial nesting waterbirds), as well as on trialling fine-scale manipulation of infrastructure (e.g. pumping) to water relatively small areas. There has been no comprehensive systematic assessment of the entire floodplain and its wider set of flood-dependent natural assets (such as ecosystems and species; herein referred to as ‘natural values’) to maximise the effectiveness of environmental water use and to catalogue values likely to be lost. This paper describes an assessment of some 220 000 ha found to support flood-dependent natural values in Victoria. We mapped the geographic distribution and estimated components of the flooding requirements (natural flooding frequency, and maximum period without flooding and minimum duration of each flooding event before significant deterioration) for each natural value. Using an example of one stretch of the River Murray, we show how the resultant spatial data can be used with floodplain inundation modelling to compare the outcomes of real or planned environmental watering events; potentially providing tools for management agencies to conserve a wider range of floodplain values than is currently the case. That is, water managers and the public can see what ecosystems and threatened species are intended to be maintained by environmental watering and what values are intended to be abandoned across the whole floodplain, rather than just seeing the small subset of values and ‘icon’ sites that are intended to be maintained. Examples are provided to illustrate how information about the location, water requirements and extent covered by potential floods for specific values can be used to build adaptive watering strategies for areas as large as the whole floodplain.

Weaving stories in digital media : when Spielberg makes home movies

In this paper we describe research aimed at enabling amateur video makers to improve both the technical quality and communicative capacity of their work. Motivated by the recognition that untold hours of home video are simply abandoned after capture, we have formulated the problem as one of defining the what and how of footage capture. We have implemented a framework that answers the first problem, the what, by means of the age-old communicative powers of Story; the second problem, the how, is addressed by means of well documented aesthetic principles that constitute the film profession, which impact both technical and cinematic considerations for a given project. We provide a brief overview of the process, beginning with the narrative template, embodying a chosen story, through the principal phases of generating a storyboard, directing, and editing, resulting in the finished product. We demonstrate the interplay of narrative, purpose for the production, and aesthetic agents, and their influence on the automatically generated storyboard with examples.

Uneasily along the sand

Uneasily Along the Sand evokes the state of mind of the great Mallee poet John Shaw Neilson during a period of hospitalization for nervous exhaustion around 1900. To his bed come the voices and apparitions of all those people whom he might have met but who in life eluded him. It is a ghost community of jesters, singers and seers, who parade in harlequin costumes and recall the poet to the vanishing spirit of the Mallee forest. In particular, a Wotjobaluk man by the name of ‘Jowley’ haunts him, a man found by white people as a child abandoned in a hollow log - abandoned, lost, stolen? The sound installation ‘Mac’ (that forms part of Uneasily and which will receive its first national broadcast to coincide with Mildura Palimpsest #8) evokes their strange meeting and a kind of reconciliation of peoples and cultures with environments that remains elusive. The hospital, where Neilson heard strange voices and saw strange visions, is evoked in a video work based on a set of ‘actions’ performed in Mildura’s Old Base Hospital, and sound recordings made in Pyrenees House, Ararat (a replica of the Swan Hill Hospital where Neilson was confined). The hospital solarium is transformed into a strangely distorted Mallee paddock, of sand, barbed wire and mattresses that leak like hour glasses. Caught in the fence lines of this dream world are scraps of a woman’s dress, bed sheets inscribed with charcoaled graffiti and footprints alluding to the ‘unevennesses’ of a life. Uneasily Along the sand is inspired by Paul Carter’s recent book, ‘Ground Truthing: explorations in a creative region’. The installation of Uneasily in Mildura coincides with Opening, another work inspired by ‘Ground Truthing’ that Carter and Dirk de Bruyn have created for the big screen at Federation Square, Melbourne.

Social reader: towards browsing the social web

We describe Social Reader, a feed-reader-plus-social-network aggregator that mines comments from social media in order to display a user’s relational neighborhood as a navigable social network. Social Reader’s network visualization enhances mutual awareness of blogger communities, facilitates their exploration and growth with a fully dragn- drop interface, and provides novel ways to filter and summarize people, groups, blogs and comments. We discuss the architecture behind the reader, highlight tasks it adds to the workflow of a typical reader, and assess their cost. We also explore the potential of mood-based features in social media applications. Mood is particularly relevant to social media, reflecting the personal nature of the medium. We explore two prototype mood-based features: colour coding the mood of recent posts according to a valence/arousal map, and a mood-based abstract of recent activity using image media. A six week study of the software involving 20 users confirmed the usefulness of the novel visual display, via a quantitative analysis of use logs, and an exit survey.

Integrating the hedonic and eudaimonic perspectives to more comprehensively understand wellbeing and pathways to wellbeing

Recently, the disagreement that separates hedonic from eudaimonic philosophers has spread to the science of wellbeing. This has resulted in two opposing perspectives regarding both wellbeing concepts and proposed pathways to wellbeing. Whilst contention continues, most contemporary psychologists now agree that hedonic and eudaimonic approaches each denote important aspects of wellbeing. This has led to integrated wellbeing conceptualisations, in which the combined presence of hedonic and eudaimonic wellbeing components is referred to as ‘flourishing’. In regard to the attainment of wellbeing, research simultaneously investigating hedonic and eudaimonic pathways suggests that a life rich in both types of pursuits is associated with the highest degree of wellbeing. Despite this assertion, previously underemphasised methodological limitations question the validity of such claims. To further progress this important area of investigation, future research directions to ameliorate said limitations are explored. It is recommended that the past tendency to contrast and compare hedonia and eudaimonia be abandoned, and instead that the inherent value of both be recognised. Time-use research methods are needed to cross-validate past findings obtained from cross-sectional research, which will make it possible to transition from purely descriptive conclusions to applied conclusions.

The Bali Aga housing : minimalist and functionalist architecture

Nusantara (Indonesia Archipelago) Architecture is a significant heritage which has been inherited to descendants. Nusantara Architecture is rooted from the existence of culture that spread over the Indonesia archipelago. The culture in each region related to their traditional customs and religions that binding the culture and physic as well as socio-culture of its society. It cannot be denied that the traditional architecture is closed to realm and tactful definitely to interact to the environment. Likewise the Balinese traditional architecture is a substantial treasure which has been inherited and maintained currently. Culture and tradition are adhered in the Tri Hita Karana philosophy, which shows how Balinese balance to their Gods, natures and fellow creatures. The concept implies in the architecture of housing as product of culture. The housing pattern of the Bali Aga villages in Bali Province which has hut forms with linear or compound pattern, it lies naturally from headwater of the mountain to downstream of the sea. The existence of Bali Aga housing stills abide and maintain that defined as reflection of minimalist and functional architecture. Example for this is some observations in the indigenous villages' i.e Pinggan Village, Buahan Village, Julah Village etc. Those housing pattern shows the minimalist concept for living facility and its functions. The discourse of traditional architecture aims to preserve Nusantara architecture which is facing nowadays as a dilemma to be abandoned.

A concrete certificateless signature scheme without pairings

Certificateless public key cryptography was introduced to avoid the inherent key escrow problem in identity-based cryptography, and eliminate the use of certificates in traditional PKI. Most cryptographic schemes in certificateless cryptography are built from bilinear mappings on elliptic curves which need costly operations. Despite the investigation of certificateless public key encryption without pairings, certificateless signature without pairings received much less attention than what it deserves. In this paper, we present a concrete pairing-free certificateless signature scheme for the first time. Our scheme is more computationally efficient than others built from pairings. The new scheme is provably secure in the random oracle model assuming the hardness of discrete logarithm problem.

A hybrid approach to fuzzy risk analysis in stock market

The analysis and prediction of stock market has always been well recognized as a difficult problem due to the level of uncertainty and the factors that affect the price. To tackle this challenge problem, this paper proposed a hybrid approach which mines the useful information utilizing grey system and fuzzy risk analysis in stock prices prediction. In this approach, we firstly provide a model which contains the fuzzy function, k-mean algorithm and grey system (shorted for FKG), then provide the model of fuzzy risk analysis (FRA). A practical example to describe the development of FKG and FRA in stock market is given, and the analytical results provide an evaluation of the method which shows promote results. © 2013 IEEE.

The geo-historical legacies of urban security governance and the Vancouver 2010 Olympics

In 2004, the discourse of ‘legacy’ was woven into the constitutional fabric of the International Olympic Committee (IOC). Bidding for Olympic events is now premised on procuring post-event legacies that will resonate through local communities and host countries long after the flame is extinguished. Given vast expenditures in security, policing, and emergency management operations at major sporting events, it is notable that the IOC and its official partners have disproportionately under-represented security and policing legacies. This paper addresses research into security and policing legacies of major events by turning much needed empirical attention towards institutional level geographies of security and policing – particularly on legacies of policing and militarisation in Olympic host cities. Accordingly, the paper traces the institutional trajectory of the Military Liaison Unit (MLU) in the Vancouver Police Department who were heavily involved in coordinating the joint civilian–military effort throughout the lifecycle of the Vancouver 2010 Winter Games. Theoretically, the paper furthers Stephen Graham’s (2010) New Military Urbanism that considers the circulation of military expertise between neo-colonial frontiers of military intervention with Western urban spaces. In doing so, this paper unpacks an empirically guided temporal approach that discerns key drivers of militarisation as localised, empirical-based ‘trajectories’ of development of security and policing institutions, which are linked to, and circumscribed by, critical juncture episodes in the context of mega event security. The paper traces processes of the MLU to explain how conditions underpinning the civil–military divide in urban policing, as a series of jurisdictional, institutional, and by extension, geographical configurations have continued, changed or been abandoned in the context of the Vancouver 2010 Olympics. As such, this paper contributes to much needed debate on the controversies and opportunities inherent in security legacies and major events, which implicate the wider securitisation and militarisation of Western cities.
