Conceptualizing user satisfaction in the ubiquitous computing era

In this research-in-progress paper we argue that technology in the ubiquitous computing era offers experiences to users that extend well beyond the functional, practical applications offered in the world of work. In this era a realm of engagement is opening up to the individual that transcends the utilitarian, to encompass hedonic and social existence. Our central argument, therefore, is that user satisfaction is a notion which must extend to encompass rich, holistic human experience involving complex and fleeting interactions, driven by highly personal circumstances. We argue that the expectations, requirements and value perceptions of individuals in this dynamic context may only be anticipated and understood if situational factors (such as location, time, context, history-of-use) and quality of life factors (such as life stage, mobility, health, income, background, education) are taken into account. We identify the fundamental differences in key characteristics of user satisfaction between the traditional and ubiquitous computing environments and provide details about our own research approach, in which we are exploring ubiquitous content provision from the perspective of content providers.

Harem size and oviposition behaviour in a polygynous bark beetle

1. Harem polygyny can have fitness benefits and costs on females. In bark beetles of the genus Ips the latter may include within-harem competition between larvae. However, earlier competition between females for male care and mating opportunities may also influence oviposition behaviour. There has been relatively little investigation into the relationship between harem size and initial egg output. The present study investigated this relationship in the bark beetle Ips grandicollis.
2. The measure of egg output used was the number of eggs in the gallery with the most eggs in each harem. Mean ( ± SE) harem size of 242 observed harems was 3.25 ± 0.10. A curvilinear relationship was found between egg output and harem size, with females in smaller harems (one to four females) laying more eggs with increased harem size. However, females in larger harems (five to seven females) laid fewer eggs as harem size increased. The optimal harem size (in terms of number of eggs laid) was close to four females.
3. We found no evidence from a behavioural assay that females could preferentially choose unmated males over mated males with harems of two females. Additionally, the distribution of harem sizes suggests that females distribute themselves among males randomly.
4. The results suggest that harem size has effects on female reproduction that extend beyond larval competition and influence patterns of oviposition. The mechanism that determines why egg laying is greatest at intermediate levels is unknown. There is no evidence that smaller harems belong to lower quality males, but females may adjust egglaying behaviour in large harems as a result of reduced male attendance or anticipated larval competition.

Privatization and performance : the case of four Australian financial institutions

This paper investigates the performance after privatization of institutions in Australian banking and insurance. Privatization was anticipated to improve firm performance in Australia and elsewhere, yet findings are mixed. A comparative institutional approach is taken to analyzing firm performance in the longer term which allows for further structural change. A CAMEL analysis of performance before and after privatization events is undertaken for four privatized institutions, two each from banking and insurance sectors. These are matched with private peer institutions. Privatized institutions are found to perform quite similarly to private peer institutions both before and after privatization.

Biological treatment of oily wastewater from gas stations by membrane bioreactor

In many Asian countries, rapid industrialization and urbanization has led to an increased number of cars, making wastewater from gas stations an important issue of concern in urban environment. This wastewater is characterized by high concentration of oil-water emulsion, which cannot be effectively removed by a conventional gravity separator. An experimental investigation on the treatability of oily wastewater from gas stations using a membrane bioreactor (MBR) system revealed that MBR system could achieve good removal efficiency with stability against shock loading. Optimum operating conditions were found to be at a hydraulic retention time of 4 h and an oil-loading rate of 1.8 kg oil m^sup -3^.d^sup -1^. It was anticipated that adding powdered activated carbon (PAC) in the MBR could help to adsorb the oils. However, operating the MBR with only microbial flocs has an advantage over adding PAC particles into the MBR, since the former condition could provide a prolonged cycle of filtration with a relatively lesser increase in transmembrane pressure.

CFL bulbs : environmentally friendly and sustainable?

The purpose of this paper is to document the positive and negative characteristics of using compact fluorescent lamps (CFL) and to raise awareness and debate about the potential negative health effects resulting from prolonged exposure to CFLs. This is a theoretical paper and, primarily, incorporates the literature and the author’s experiences of CFLs. Governmental and non-governmental measures in the area of recycling and disposal of CFLs are also presented. This is a relatively new area of research; hence, very limited academic literature is currently available. Discussion of the issue of increased usage of CFLs is timely following heightened debate on greenhouse gas emissions and climate change. Increased debate amongst the policy and decision-makers will assist the public to make an informed decision. It is also anticipated that this debate will put pressure on the manufacturers of all types of bulbs, and government and non-governmental agencies to enhance their own and community initiatives to recycle and/or safely dispose of CFLs. No other similar review of the advantages and weaknesses of using CFLs has been undertaken that encourages the reader and potential users of CFLs to reflect on their choices.

Living to tell the tale : survival and connection

Memories too sharp for public handling most often stay in our private worlds where we all live, at some point or other, with the weight of regret, or sadness of things lost. The idea of living to tell the tale becomes in itself the story, and we keep counsel with that idea in early morning dreams, or late night fears. For most of us, that is as far as our story goes. Some women, however, move beyond that instinctive silence born of trauma. When the story they have to tell is also a trauma of nationality, of intercultural connection, and of women’s shared sense of survival, it can be tough reading. Judith McNeil’s memoir, The Girl With the Cardboard Port was set down, like this, in front of me.

The impact of emotions on practicum learning

Nine mature aged, experienced practitioners enrolled to gain a BSW qualification in social work were interviewed regarding a course requirement to complete the first placement. At the time of interview no recognition of prior learning for previous experience in the field was made possible for these students. As educators we had experienced considerable hostility from students who believed they should be exempt from completing this course requirement. This paper reports on interviews with the nine students, where we consider how student sentiment about completing the practice learning component might impact upon their learning experience. As anticipated, some students expressed strong negative views about being on placement. However, others were much more positive about the experience. These mixed views prompted us to explore further the relationship between emotion and practice learning. The article begins with a review of the literature concerning mature student engagement with tertiary education, followed by an overview of theory and research related to the ways feelings and emotion influence learning. Using passages from the interviews, expressions of participant anxiety, anger and excitement about the practicum are discussed with the view to extending discourse about practicum learning to include consideration of emotional intelligence and investment.

Wi-Fi security : wireless with confidence

Since the IEEE ratification of the 802.11 standard in 1999, continuous exploits have been discovered compromising the confidentiality, integrity and availability of 802.11 networks. This paper describes the justification for a project to assess the security status of wireless network usage in society. It reviews the status of both commercial and residential approaches to wireless network security in three major Victorian cities, Melbourne, Geelong and Mornington, in Australia. By War Driving these suburbs, actual data was gathered to indicate the security status of wireless networks and give a representation of modern attitudes towards wireless security for the sample population. Preliminary results are presented to demonstrate the extent to which commercial or residential suburbs address wireless security. At this stage in the research further work is required to completely analyse the results. It is anticipated that the results will be useful for providing input into a defence and attack methodology for improving the security of both residential and commercial use of wireless networks.

Leaving the professional tennis circuit : exploratory study of experiences and reactions from elite female athletes

In 2002, Tennis Australia commissioned a report into the experiences of elite female past players on leaving the professional tennis circuit. Australian players who were in the top 800 of the Women’s Tennis Association (WTA) end of year rankings and who had left the professional circuit within the previous 15 years were asked by mail to respond to a questionnaire. The questionnaire asked players to describe their feelings about leaving the tour during the time leading up to leaving the tour to two years after retirement. The main findings of the study suggested that those who planned to leave the tour found the transition process easy, whereas those who did not plan to leave the tour found the process difficult. Most players (66%) did not regret leaving the tour, and, although the remaining players responded that they regretted leaving, none attempted a comeback. Tennis Australia has implemented strategies to assist current players on the professional tour based on the results of this study.

Estuary environmental flows assessment methodology : final specification report

This report provides a consistent and systematic approach to the determination of environmental water requirements for estuaries in Victoria.

Victoria’s limited water resources are subject to competing demands. These demands, including town water supplies and irrigation requirements, often deplete the flow entering estuaries and put their environmental values at risk.

The Estuary Environmental Flows Assessment Methodology (EEFAM) is a standard methodology which can be applied in a consistent manner across all Victorian estuaries, according to their priority. It is not anticipated that this method would be used for the Gippsland Lakes or Port Phillip or Western Port Bay.

Primary hemiarthroplasty for treatment of proximal humeral fractures

Background: Primary hemiarthroplasty of the shoulder is used to treat complex proximal humeral fractures, although the reported functional results following this method of treatment have varied widely. The aim of this study was to prospectively assess the prosthetic survival and functional outcomes in a large series of patients treated with shoulder hemiarthroplasty for a proximal humeral fracture. By determining the factors that affected the outcome, we also aimed to produce models that could be used clinically to estimate the functional outcome at one year following surgery.

Methods: A thirteen-year observational cohort study of 163 consecutive patients treated with hemiarthroplasty for a proximal humeral fracture was performed. Twenty-five patients died or were lost to follow-up in the first year after treatment, leaving 138 patients who had assessment of shoulder function with use of the modified Constant score at one year postinjury.

Results: The overall rate of prosthetic survival was 96.9% at one year, 95.3% at five years, and 93.9% at ten years. The overall median modified Constant score was 64 points at one year, with a typically good score for pain relief (median, 15 points) and poorer scores, with a greater scatter of values, for function (median, 12 points), range of motion (median, 24 points), and muscle power (median, 14 points). Of the factors that were assessed immediately after the injury, only patient age, the presence of a neurological deficit, tobacco usage, and alcohol consumption were significantly predictive of the one-year Constant score (p < 0.05). Of the factors that were assessed at six weeks postinjury, those that predicted the one-year Constant score included the age of the patient, the presence of a persistent neurological deficit, the need for an early reoperation, the degree of displacement of the prosthetic head from the central axis of the glenoid seen radiographically, and the degree of displacement of the tuberosities seen radiographically.

Conclusions: Primary shoulder hemiarthroplasty performed for the treatment of a proximal humeral fracture in medically fit and cooperative adults is associated with satisfactory prosthetic survival at an average of 6.3 years. Although the shoulder is usually free of pain following this procedure, the overall functional result, in terms of range of motion, function, and power, at one year varies. A good functional outcome can be anticipated for a younger individual who has no preoperative neurological deficit, no postoperative complications, and a satisfactory radiographic appearance of the shoulder at six weeks. The results are poorer in the larger group of elderly patients who undergo this procedure, especially if they have a neurological deficit, a postoperative complication requiring a reoperation, or an eccentrically located prosthesis with retracted tuberosities.

TEALS (Tool for Evaluation of Academic Library Spaces) project : evaluating physical library spaces

The aim of TEALS project was to establish a setting for evaluation of academic library spaces. The outcomes of such evaluation were anticipated to provide insights into the impacts of library spaces on students’ learning experiences, faculty’s teaching and research and lead to identifying the area of weakness and strength, developing improvement plans and defining specific goals and means for project decision-makers.

Comparison of the traditional problem-based learning format and larger, directed, independent study groups

 Problem based learning has been implemented as a pedagogical tool world-wide across a range of health professions since its inception at McMaster University, Canada, in 1969 (Neville & Norman, 2007). In addition to enhancing knowledge and understanding it is also claimed that PBL develops communication skills, encourages teamwork, sharing of information and respect for others, furthers problem solving skills, and allows students to assume responsibility for their own learning (Wood, 2003). However, the cognitive outcomes of PBL and traditional pedagogy (based on didactic teaching) are similar and hence widespread adoption of PBL has been questioned (see Colliver, 2000). Criticisms of PBL include its resource hungry nature, requiring, as it does, experienced tutors to facilitate .learning across several clusters of students dealing with the same problem. Given the actual and anticipated increase in numbers of medical students in Australia other strategies that retain the advantages of PBL, while minimising the demands on faculty, should now be explored. This paper reports our experience with a modification of the traditional PBL approach, termed PBLplus. This innovation was trialled in a regional clinical school, attached to a hospital, with a group of 19 graduate entry students, who had completed an integrated Year 1 / 2 of the MBBS. PBLplus involved allocating students from the whole class to three task directed groups. Groups had specified assignments to complete to facilitate learning across the whole class. A tutor listened to student presentations and provided an interactive presentation. Hence use of tutors was made more efficient, and faculty input was more specialised.

Color, champagne, and trademark secondary meaning surveys : devilish detail

This article first outlines the requirements for trademarking color and describes the VEUVE CLICQUOT brand. It then describes possible designs for testing whether the color orange serves as a trademark. For each element of the survey, the design dilemmas that must be resolved prior to implementation are described, and specific solutions to these design dilemmas are suggested. As a final contribution, the article looks at arguments that may be raised against the design elements and suggests ways that these arguments may be anticipated and minimized by using a specific design logic. In this way, this article will help expert researchers produce specific, defensible designs that will be of use to courts and tribunals.

Understanding the role of social media monitoring in generating external intelligence

Social media data are becoming increasingly critical for businesses to capture, analyse, and utilise in a timely manner. However, the unstructured and distributed nature and volume of this information makes the task of extracting useful and practical information challenging. Given the dynamic evolution of social media and social media monitoring, our current understanding of how social media monitoring can help organisations to create business value is inadequate. As a result, there is a need to study how organisations can (a) extract and analyse social media data related to their business (Sensing), and (b) utilise external intelligence gained from social media monitoring for specific business initiatives (Seizing). This study uses a qualitative approach with a multiple embedded case study design to understand the phenomenon of social media monitoring and its outcome for organisations. Anticipated contributions are presented.
