Augmenting process elicitation with visual priming: An empirical exploration of user behaviour and modelling outcomes

Business process models have become an effective way of examining business practices to identify areas for improvement. While common information gathering approaches are generally efficacious, they can be quite time consuming and have the risk of developing inaccuracies when information is forgotten or incorrectly interpreted by analysts. In this study, the potential of a role-playing approach to process elicitation and specification has been examined. This method allows stakeholders to enter a virtual world and role-play actions similarly to how they would in reality. As actions are completed, a model is automatically developed, removing the need for stakeholders to learn and understand a modelling grammar. An empirical investigation comparing both the modelling outputs and participant behaviour of this virtual world role-play elicitor with an S-BPM process modelling tool found that while the modelling approaches of the two groups varied greatly, the virtual world elicitor may not only improve both the number of individual process task steps remembered and the correctness of task ordering, but also provide a reduction in the time required for stakeholders to model a process view.

The development and preliminary evaluation of an education intervention to prevent driveway run-over incidents

Objective While driveway run-over incidents continue to be a cause of serious injury and deaths among young children in Australia, few empirically evaluated educational interventions have been developed which address these incidents. Addressing this gap, this study describes the development and evaluation of a paper-based driveway safety intervention targeting caregivers of children aged 5 years or younger. Design Cross-sectional survey. Method and setting Informed by previous research, the intervention targeted key caregiver safety behaviours that address driveway risks. To assess the impact of the intervention, 137 Queensland (Australia) caregivers (95.0% women; mean age = 34.97 years) were recruited. After receiving the intervention, changes to a number of outcomes such as caregiver risk perception, safety knowledge and behavioural intentions were measured. Results Findings indicated that the intervention had increased general and specific situational risk awareness and safety knowledge among a substantial proportion of participants. Close to one-quarter of the sample strongly agreed that the intervention had increased these outcomes. In addition, 71.6% of the sample reported that they intended to make changes to their routine in and around the driveway, as a result of reading the intervention material and a further, quarter of the participants strongly agreed that the information provided would be a help both to themselves (26.5%) and other caregivers (33.8%) to keep their children safe in the driveway. Conclusion: While the educational intervention requires further validation, findings from this study suggest that intervention content and format increases driveway safety.

IMPOSE (IMProving Outcomes after Sepsis)—the effect of a multidisciplinary follow-up service on health-related quality of life in patients postsepsis syndromes—a double-blinded randomised controlled trial: protocol

Introduction Patients post sepsis syndromes have a poor quality of life and a high rate of recurring illness or mortality. Follow-up clinics have been instituted for patients postgeneral intensive care but evidence is sparse, and there has been no clinic specifically for survivors of sepsis. The aim of this trial is to investigate if targeted screening and appropriate intervention to these patients can result in an improved quality of life (Short Form 36 health survey (SF36V.2)), decreased mortality in the first 12 months, decreased readmission to hospital and/or decreased use of health resources. Methods and analysis 204 patients postsepsis syndromes will be randomised to one of the two groups. The intervention group will attend an outpatient clinic two monthly for 6 months and receive screening and targeted intervention. The usual care group will remain under the care of their physician. To analyse the results, a baseline comparison will be carried out between each group. Generalised estimating equations will compare the SF36 domain scores between groups and across time points. Mortality will be compared between groups using a Cox proportional hazards (time until death) analysis. Time to first readmission will be compared between groups by a survival analysis. Healthcare costs will be compared between groups using a generalised linear model. Economic (health resource) evaluation will be a within-trial incremental cost utility analysis with a societal perspective. Ethics and dissemination Ethical approval has been granted by the Royal Brisbane and Women’s Hospital Human Research Ethics Committee (HREC; HREC/13/QRBW/17), The University of Queensland HREC (2013000543), Griffith University (RHS/08/14/HREC) and the Australian Government Department of Health (26/2013). The results of this study will be submitted to peer-reviewed intensive care journals and presented at national and international intensive care and/or rehabilitation conferences.

Evaluating the effectiveness of a self-management exercise intervention on wound healing, functional ability and health-related quality of life outcomes in adults with venous leg ulcers: a randomised controlled trial

Exercise that targets ankle joint mobility may lead to improvement in calf muscle pump function and subsequent healing. The objectives of this research were to assess the impact of an exercise intervention in addition to routine evidence-based care on the healing rates, functional ability and health-related quality of life for adults with venous leg ulcers (VLUs). This study included 63 patients with VLUs. Patients were randomised to receive either a 12-week exercise intervention with a telephone coaching component or usual care plus telephone calls at the same timepoints. The primary outcome evaluated the effectiveness of the intervention in relation to wound healing. The secondary outcomes evaluated physical activity, functional ability and health-related quality of life measures between groups at the end of the 12 weeks. A per protocol analysis complemented the effectiveness (intention-to-treat) analysis to highlight the importance of adherence to an exercise intervention. Intention-to-treat analyses for the primary outcome showed 77% of those in the intervention group healed by 12 weeks compared to 53% of those in the usual care group. Although this difference was not statistically significant due to a smaller than expected sample size, a 24% difference in healing rates could be considered clinically significant. The per protocol analysis for wound healing, however, showed that those in the intervention group who adhered to the exercise protocol 75% or more of the time were significantly more likely to heal and showed higher rates for wound healing than the control group (P = 0·01), that is, 95% of those who adhered in the intervention group healed in 12 weeks. The secondary outcomes of physical activity, functional ability and health-related quality of life were not significantly altered by the intervention. Among the secondary outcomes (physical activity, functional ability and health-related quality of life), intention-to-treat analyses did not support the effectiveness of the intervention. However, per protocol analyses revealed encouraging results with those participants who adhered more than 75% of the time (n = 19) showing significantly improved Range of Ankle Motion from the self-management exercise programme (P = 0·045). This study has shown that those participants who adhere to the exercise programme as an adjunctive treatment to standard care are more likely to heal and have better functional outcomes than those who do not adhere to the exercises in conjunction with usual care.

Morbid obesity in total hip arthroplasty: Redefining outcomes for operative time, length of stay, and readmission

Background The incidence of obesity amongst patients presenting for elective Total Hip Arthroplasty (THA) has increased in the last decade and the relationship between obesity and the need for joint replacement has been demonstrated. This study evaluates the effects of morbid obesity on outcomes following primary THA by comparing short-term outcomes in THA between a morbidly obese (BMI ≥40) and a normal weight (BMI 18.5 - <25) cohort at our institution between January 2003 and December 2010. Methods Thirty-nine patients included in the morbidly obese group were compared with 186 in the normal weight group. Operative time, length of stay, complications, readmission and length of readmission were compared. Results Operative time was increased in the morbidly obese group at 122 minutes compared with 100 minutes (p=0.002). Post-operatively there was an increased 30-day readmission rate related to surgery of 12.8% associated with BMI ≥40 compared with 2.7% (p= 0.005) as well as a 5.1 fold increase in surgery related readmitted bed days - 0.32 bed days per patient for normal weight compared with 1.64 per patient for the morbidly obese (p=0.026). Conclusion Morbidly obese patients present a technical challenge and likely this and the resultant complications are underestimated. More work needs to be performed in order to enable suitable allocation of resources.

Carer perspectives of factors affecting placement trajectories of children in out-of-home care

Carers are at the frontline working with children in the care of the child protection system. This paper reports carer's views about key factors influencing the placement trajectories of children and young people living in out-of-home care in Queensland, Australia. The study sample included 21 foster and kinship carers with a minimum two-year experience in the carer role. Study data were from semi-structured telephone interviews in which carers shared their experiences of the factors impacting upon placement stability and placement movement. Carers' responses were analysed thematically. Data analysis yielded an overarching theme regarding placement trajectory: Carer engagement, and its three sub-themes; with the child; with the child protection system; and, with the caring role. Findings suggested that carer engagement and ‘fit’ are complex constructs that play critical influential roles in placement outcomes (stability or movement) for individual children in out-of-home care. It is argued that practice needs to be better grounded in these relational dynamics, and better aligned concerning the power differentials that exist.

Performance based planning in Queensland : A case of unintended plan-making outcomes

Performance based planning (PBP) is purported to be a viable alternative to traditional zoning. The implementation of PBP ranges between pure approaches that rely on predetermined quantifiable performance standards to determine land use suitability, and hybrid approaches that rely on a mix of activity based zones in addition to prescriptive and subjective standards. Jurisdictions in the USA, Australia and New Zealand have attempted this type of land use regulation with varying degrees of success. Despite the adoption of PBP legislation in these jurisdictions, this paper argues that a lack of extensive evaluation means that PBP is not well understood and the purported advantages of this type of planning are rarely achieved in practice. Few empirical studies have attempted to examine how PBP has been implemented in practice. In Queensland, Australia, the Integrated Planning Act 1997 (IPA) operated as Queensland's principal planning legislation between March 1998 and December 2009. While the IPA did not explicitly use the term performance based planning, the Queensland's planning system is widely considered to be performance based in practice. Significantly, the IPA prevented Local Government from prohibiting development or use and the term zone was absent from the legislation. How plan-making would be advanced under the new planning regime was not clear, and as a consequence local governments produced a variety of different plan-making approaches to comply with the new legislative regime. In order to analyse this variation the research has developed a performance adoption spectrum to classify plans ranging between pure and hybrid perspectives of PBP. The spectrum compares how land use was regulated in seventeen IPA plans across Queensland. The research found that hybrid plans predominated, and that over time a greater reliance on risk adverse drafting approaches created a quasi-prohibition plan, the exact opposite of what was intended by the IPA. This paper concludes that the drafting of the IPA and absence of plan-making guidance contributed to lack of shared understanding about the intended direction of the new planning system and resulted in many administrative interpretations of the legislation. It was a planning direction that tried too hard to be different, and as a result created a perception of land use risk and uncertainty that caused a return to more prescriptive and inflexible plan-making methods.

Alcohol and depression

"A large proportion of people who experience drug problems also experience a range of mental health problems. Similarly, many people who experience mental health problems engage in hazardous drug use. The experience of these co-occurring disorders increases use of treatment services, but is associated with poorer prognosis. The implementation of effective responses has been hindered by the disaggregated systems of care that have been adopted in many countries; many problems are the outcome of poorly organised systems of care that do not reflect the needs of a large proportion of clients who experience various problems. There is a dearth of quality research to guide the development of evidence-based responses to co-occurring drug and mental health problems. This book introduces the reader to the issues, guided by a series of questions. These encourage the reader to consider the evidence about the nature and prevalence of co-occurring disorders and the challenges they create for individuals, the community and service providers. The diverse range of expertise of the contributors provides the opportunity to consider the challenges of navigating the various systems of care from the perspective of consumers, parents and clinicians. Researchers and clinicians examine the available evidence about the links between the various disorders and discuss the implications for treatment through a series of case studies. The reader is guided through evidence-based clinical decision-making. The editor and contributors argue that, while our knowledge and expertise is improving, there is a need to better resource and integrate treatment services to foster the adoption of evidence-based and effective responses. Poor systems of care don’t necessarily cause co-occurring mental health and drug problems, but they can contribute to poor outcomes."--Publisher website

The good, the bad and the ugly of bone-anchored prostheses: Guideline to assess true clinical outcomes

The aim of this study is to share the key elements of an evaluation framework to determine the true clinical outcomes of bone-anchored prostheses. Scientists, clinicians and policy makers are encouraged to implement their own evaluations relying on the proposed framework using a single database to facilitate reflective practice and, eventually, robust prospective studies.

“Well this is it. Just get on with it”: Pain willingness and activity engagement in people with chronic pain

Pain is recognised as a problem of significant concern worldwide and in the latest Global Burden of Disease Study, low back pain was identified as the biggest contributor worldwide to Years Lived with Disability. There is evidence to suggest that people who accept their chronic pain have a higher quality of life, lower levels of disability and distress, and function better emotionally, socially and physically. Findings on the specific pathways linking pain acceptance to quality of life outcomes are less clear. the two widely accepted pain acceptance factors, pain willingness and activity engagement, have not been well explored in qualitative studies on acceptance of chronic pain. To address this deficit in the literature, the current study has two related aims: 1) to explore pain willingness and activity engagement in the lives of people with chronic pain, and ; 2) to find out what people believe helps them to successfully get on with life in spite of chronic pain.

A cultural assessment of family dispute resolution: Findings about access, retention and outcomes from the evaluation of a Family Relationship Centre

The cultural appropriateness of human service processes is a major factor in determining the effectiveness of their delivery. Sensitivity to issues of culture is particularly critical in dealing with family disputes, which are generally highly emotive and require difficult decisions to be made regarding children, material assets and ongoing relationships. In this article we draw on findings from an evaluation of the Family Relationship Centre at Broadmeadows (FRCB) to offer some insights into and suggestions about managing cultural matters in the current practice of family dispute resolution (FDR) in Australia. The brief for the original research was to evaluate the cultural appropriateness of FDR services offered to culturally and linguistically diverse (CALD) communities living within the FRCB’s catchment area, specifically members of the Lebanese, Turkish and Iraqi communities. The conclusions of the evaluations were substantially positive. The work of the Centre was found to illustrate many aspects of best practice but also raised questions worthy of future exploration. The current article reports on issues of access, retention and outcomes obtained by CALD clients at various stages of the FRCB service.

Non-small cell lung cancer : studies on pathogenesis, tumour targeting and treatment outcomes

Lung cancer accounts for more cancer-related deaths than any other cancer. In Finland, five-year survival ranges from 8% to 13%. The main risk factor for lung cancer is long-term cigarette smoking, but its carcinogenesis requires several other factors. The aim of the present study was to 1) evaluate post-operative quality of life, 2) compare clinical outcomes between minimally invasive and conventional open surgery, 3) evaluate the role of oxidative stress in the carcinogenesis of non-small lung cancer (NSCLC), and 4) to identify and characterise targeted agents for therapeutic and diagnostic use in surgery. For study I, pneumonectomy patients replied to 15D quality of life and baseline dyspnea questionnaires. Study III involved a prospective quality of life assessment using the 15D questionnaire after lobectomy or bi-lobectomy. Study IV was a retrospective comparison of clinical outcomes between 212 patients treated with open thoracotomy and 116 patients who underwent a minimally invasive technique. Study II measured parameters of oxidative metabolism (myeloperoxidase activity, glutathione content and NADPH oxidase activity) and DNA adducts. Study V employed the phage display method and identified a core motif for homing peptides. This method served in cell-binding, cell-localisation, and biodistribution studies. Following both pneumonectomy and lobectomy, NSCLC patients showed significantly decreased long-term quality of life. No significant correlation was noted between post-operative quality of life and pre-operative pulmonary function tests. Women suffered more from increased dyspnea after pneumonectomy which was absent after lobectomy or bi-lobectomy. Patients treated with video-assisted thoracoscopy showed significantly decreased morbidity and shorter periods of hospitalization than did open surgery patients. This improvement was achieved even though the VATS patients were older and suffered more comorbid conditions and poorer pulmonary function. No significant differences in survival were noted between these two groups. An increase in NADPH oxidase activity was noted in tumour samples of both adenocarcinoma and squamous cell carcinoma. This increase was independent from myeloperoxidase activity. Elevated glutathione content was noted in tumour tissue, especially in adenocarcinoma. After panning the clinical tumour samples with the phage display method, an amino acid sequence of ARRPKLD, the Thx, was chosen for further analysis. This method proved selective of tumour tissue in both in vitro and in vivo cell-binding assay, and biodistribution showed tumour accumulation. Because of the significantly reduced quality of life following pneumonectomy, other operative strategies should be implemented as an alternative (e.g. sleeve-lobectomy). To treat this disease, implementation of a minimally invasive surgical technique is safe, and the results showed decreased morbidity and a shorter period of hospitalisation than with thoracotomy. This technique may facilitate operative treatment of elderly patients with comorbid conditions who might otherwise be considered inoperable. Simultaneous exposure to oxidative stress and altered redox states indicates the important role of oxidative stress in the pathogenesis and malignant transformation of NSCLC. The studies showed with great specificity and with favourable biodistribution that Thx peptide is specific to NSCLC tumours. Thx thus shows promise in imaging, targeted therapy, and monitoring of treatment response.

Bicriterion differential games with qualitative outcomes

Combat games are studied as bicriterion differential games with qualitative outcomes determined by threshold values on the criterion functions. Survival and capture strategies of the players are defined using the notion of security levels. Closest approach survival strategies (CASS) and minimum risk capture strategies (MRCS) are important strategies for the players identified as solutions to four optimization problems involving security levels. These are used, in combination with the preference orderings of the qualitative outcomes by the players, to delineate the win regions and the secured draw and mutual kill regions for the players. It is shown that the secured draw regions and the secured mutual kill regions for the two players are not necessarily the same. Simple illustrative examples are given.

A modell of socially optimal hydro reservoir usage - yelding socially optimal outcomes in nordic electricity markets

An extensive electricity transmission network facilitates electricity trading between Finland, Sweden, Norway and Denmark. Currently most of the area's power generation is traded at NordPool, where the trading volumes have steadily increased since the early 1990's, when the exchange was founded. The Nordic electricity is expected to follow the current trend and further integrate with the other European electricity markets. Hydro power is the source for roughly a half of the supply in the Nordic electricity market and most of the hydro is generated in Norway. The dominating role of hydro power distinguishes the Nordic electricity market from most of the other market places. Production of hydro power varies mainly due to hydro reservoirs and demand for electricity. Hydro reservoirs are affected by water inflows that differ each year. The hydro reservoirs explain remarkably the behaviour of the Nordic electricity markets. Therefore among others, Kauppi and Liski (2008) have developed a model that analyzes the behaviour of the markets using hydro reservoirs as explanatory factors. Their model includes, for example, welfare loss due to socially suboptimal hydro reservoir usage, socially optimal electricity price, hydro reservoir storage and thermal reservoir storage; that are referred as outcomes. However, the model does not explain the real market condition but rather an ideal situation. In the model the market is controlled by one agent, i.e. one agent controls all the power generation reserves; it is referred to as a socially optimal strategy. Article by Kauppi and Liski (2008) includes an assumption where an individual agent has a certain fraction of market power, e.g. 20 % or 30 %. In order to maintain the focus of this thesis, this part of their paper is omitted. The goal of this thesis is two-fold. Firstly we expand the results from the socially optimal strategy for years 2006-08, as the earlier study finishes in 2005. The second objective is to improve on the methods from the previous study. This thesis results several outcomes (SPOT-price and welfare loss, etc.) due to socially optimal actions. Welfare loss is interesting as it describes the inefficiency of the market. SPOT-price is an important output for the market participants as it often has an effect on end users' electricity bills. Another function is to modify and try to improve the model by means of using more accurate input data, e.g. by considering pollution trade rights effect on input data. After modifications to the model, new welfare losses are calculated and compared with the same results before the modifications. The hydro reservoir has the higher explanatory significance in the model followed by thermal power. In Nordic markets, thermal power reserves are mostly nuclear power and other thermal sources (coal, natural gas, oil, peat). It can be argued that hydro and thermal reservoirs determine electricity supply. Roughly speaking, the model takes into account electricity demand and supply, and several parameters related to them (water inflow, oil price, etc.), yielding finally the socially optimal outcomes. The author of this thesis is not aware of any similar model being tested before. There have been some other studies that are close to the Kauppi and Liski (2008) model, but those have a somewhat different focus. For example, a specific feature in the model is the focus on long-run capacity usage that differs from the previous studies on short-run market power. The closest study to the model is from California's wholesale electricity markets that, however, uses different methodology. Work is constructed as follows.

Pilottitutkimus apteekkien yksilöllisestä tupakoinninvieroituspalvelusta

Apteekkien yksilöllinen tupakoinninvieroituspalvelu on tupakoinnin lopettamiseen motivoituneille asiakkaille tarkoitettu maksullinen erikoispalvelu, joka sisältää 4–6 tapaamista vieroitusohjaajana toimivan farmaseutin tai proviisorin kanssa. Palvelu sisältää asiakkaalle räätälöityä neuvontaa, henkilökohtaisen vieroitussuunnitelman sekä seurantajakson. Apteekkien yksilöllinen tupakoinninvieroituspalvelu perustuu Isossa-Britanniassa kehitettyyn palvelumalliin, ja sitä on tarjottu suomalaisissa apteekeissa vuodesta 2006. Tämä pro gradu -tutkielma käsittelee apteekkien yksilöllisen tupakoinninvieroituspalvelun pilottitutkimusta, joka toteutettiin Suomen Apteekkariliiton ja Helsingin yliopiston farmasian tiedekunnan sosiaalifarmasian osaston yhteistyönä ja se kuului osana Hengitysliitto Heli ry:n koordinoimaa tupakasta vieroituksen hankekokonaisuutta. Tässä pro gradu -tutkielmassa tarkastellaan pilottitutkimuksessa saadun asiakasaineiston avulla apteekkien yksilöllisen tupakoinninvieroituspalvelumallin toimivuutta, asiakkaiden kokemuksia palvelusta, asiakkaiden onnistumista tupaakoinnin lopettamisessa sekä asiakkaiden kyvykkyyden tunteen kehittymistä palvelun aikana. Tässä interventiotutkimuksessa oli mukana 14 apteekkia, jotka rekrytoivat yhteensä 36 palveluasiakasta. Ennen asiakkaiden rekrytointia apteekit perehdytettiin palvelun tarjoamiseen. Apteekit tiedottivat pilottitutkimuksesta paikallisen terveydenhuollon lääkäreitä ja muita terveydenhuollon ammattilaisia, jotka voivat ohjata asiakkaita palveluun. Sosiaali- ja terveysministeriön pilottitutkimukselle myöntämä rahoitus mahdollisti asiantuntijapalkkion maksamisen apteekeille ja palvelun tarjoamisen asiakkaille ilmaiseksi tai pientä omakustannusosuutta vastaan. Asiakkaiden tupakoimattomana pysymistä sekä kokemuksia tupakoinninvieroituspalvelusta kartoitettiin kyselylomakkeilla, jotka asiakkaat saivat täytettäväkseen palvelun alussa sekä noin 3 kuukauden kohdalla palvelun alkamisesta. Asiakkaiden taustatiedot kerättiin ensimmäisen tapaamisen yhteydessä erillisille taustatietolomakkeille ja palvelun aikana tehtyjä huomioita niille tarkoitetuille kaavakkeille. Ensimmäisen kyselylomakkeen palauttaneista 28 henkilöstä 20 ja toisen kyselylomakkeen palauttaneista 17 henkilöstä 13 oli pysynyt tupakoimattomana (55,6 % ja 36,1 % kaikista asiakkaista). Kaikki tupakoinnin lopettaneet käyttivät jotakin tupakasta vieroituslääkettä. Tupakoinnin lopettaneilla asiakkailla kyvykkyyden tunne oli keskimääräistä parempi sekä palvelun alussa että koko palvelun ajan. Asiakkaat pitivät palvelua tarpeellisena ja apteekin vieroitusohjaajalta saatua tukea tärkeänä. Asiakkaat kokivat myös palvelun saamisen apteekista tärkeäksi. Noin 32 % ensimmäiseen kyselyyn vastanneista ja 41 % toiseen kyselyyn vastanneista oli valmis maksamaan palvelusta. Heidän ilmoittamansa maksuvalmius oli keskimäärin noin 45 euroa (10–100 euroa). Muusta terveydenhuollosta lähetettiin palveluun vain vähän tai ei lainkaan asiakkaita. Tästä syystä apteekit rekrytoivat asiakkaita myös ilman kontaktia muuhun terveydenhuoltoon. Palvelun 36 asiakkaasta noin 36 % oli pysynyt tupakoimattomana 3 kuukauden kohdalla. Verrokkiryhmä jouduttiin jättämään tutkimuksesta pois verrokkihenkilöiden rekrytoinnin epäonnistuttua. Tulos on kuitenkin vertailukelpoinen kansainvälisiin tutkimuksiin, joissa on saatu vastaavanlaisia tuloksia. Apteekkien yksilöllisestä tupakoinninvieroituspalvelusta saattaa olla hyötyä tupakoinnin lopettamisessa siihen motivoituneille henkilöille ja erityisesti henkilöille, jotka käyttävät lisäksi tupakasta vieroituslääkettä. Asiakkaat kokivat palvelun tärkeäksi ja tarpeelliseksi, mutta heikko maksuvalmius asettaa haasteita palvelun tarjoamiselle apteekeissa. Yhteistyömallia muun terveydenhuollon kanssa tulisi kehittää.
