Consumer’s persistence in solving their own problem with self‐service technology

An increasing range of technology services are now offered on a self-service basis. However, problems with self-service technologies (SSTs) occur at times due to the technical error, staff error, or consumers’ own mistakes. Considering the role of consumers as co-producers in the SST context, we aim to study consumer’s behaviours, strategies, and decision making in solving their problem with SST and identify the factors contributing to their persistence in solving the problem. This study contributes to the information systems research, as it is the first study that aims to identify such a process and the factors affecting consumers’ persistence in solving their problem with SST. A focus group with user support staff has been conducted, yielding some initial results that helped to conduct the next phases of the study. Next, using Critical Incident Technique, data will be gathered through focus groups with users, diary method, and think-aloud method.

Practical linkages between cultural policy and education policy in promoting a creative workforce for youth in Tanzania

The broad aim of of this thesis is to contribute to understanding how the relationships between culture, employment and education can help Tanzania's young people secure jobs, and survive in the creative workforce so as to better their future. Based on a range of interviews and other data in Tanzania, the study considers how to integrate cultural expressions into arts education (education in art and education through art) as a tool for nurturing young people's creative talents for their future sustainable employment in Tanzania.

Research on injury compensation and health outcomes : ignoring the problem of reverse causality led to a biased conclusion

Objective This study highlights the serious consequences of ignoring reverse causality bias in studies on compensation-related factors and health outcomes and demonstrates a technique for resolving this problem of observational data. Study Design and Setting Data from an English longitudinal study on factors, including claims for compensation, associated with recovery from neck pain (whiplash) after rear-end collisions are used to demonstrate the potential for reverse causality bias. Although it is commonly believed that claiming compensation leads to worse recovery, it is also possible that poor recovery may lead to compensation claims—a point that is seldom considered and never addressed empirically. This pedagogical study compares the association between compensation claiming and recovery when reverse causality bias is ignored and when it is addressed, controlling for the same observable factors. Results When reverse causality is ignored, claimants appear to have a worse recovery than nonclaimants; however, when reverse causality bias is addressed, claiming compensation appears to have a beneficial effect on recovery, ceteris paribus. Conclusion To avert biased policy and judicial decisions that might inadvertently disadvantage people with compensable injuries, there is an urgent need for researchers to address reverse causality bias in studies on compensation-related factors and health.

Open problem: Shifting experts on easy data

A number of online algorithms have been developed that have small additional loss (regret) compared to the best “shifting expert”. In this model, there is a set of experts and the comparator is the best partition of the trial sequence into a small number of segments, where the expert of smallest loss is chosen in each segment. The regret is typically defined for worst-case data / loss sequences. There has been a recent surge of interest in online algorithms that combine good worst-case guarantees with much improved performance on easy data. A practically relevant class of easy data is the case when the loss of each expert is iid and the best and second best experts have a gap between their mean loss. In the full information setting, the FlipFlop algorithm by De Rooij et al. (2014) combines the best of the iid optimal Follow-The-Leader (FL) and the worst-case-safe Hedge algorithms, whereas in the bandit information case SAO by Bubeck and Slivkins (2012) competes with the iid optimal UCB and the worst-case-safe EXP3. We ask the same question for the shifting expert problem. First, we ask what are the simple and efficient algorithms for the shifting experts problem when the loss sequence in each segment is iid with respect to a fixed but unknown distribution. Second, we ask how to efficiently unite the performance of such algorithms on easy data with worst-case robustness. A particular intriguing open problem is the case when the comparator shifts within a small subset of experts from a large set under the assumption that the losses in each segment are iid.

The private problem with public service: Rural teachers in educational markets

Staffing rural and remote schools is an important policy issue for the public good. This paper examines the private issues it also poses for teachers with families working in these communities, as they seek to reconcile careers with educational choices for children. The paper first considers historical responses to staffing rural and remote schools in Australia, and the emergence of neoliberal policy encouraging marketisation of the education sector. We report on interviews about considerations motivating household mobility with 11 teachers across regional, rural and remote communities in Queensland. Like other middle-class parents, these teachers prioritised their children’s educational opportunities over career opportunities. The analysis demonstrates how teachers in rural and remote communities constitute a special group of educational consumers with insider knowledge and unique dilemmas around school choice. Their heightened anxieties around school choice under neoliberal policy are shown to contribute to the public issue of staffing rural and remote schools.

The effects of parental illness and other ill family members on youth caregiving experiences

Informed by a model of family role-redistribution derived from the Family Ecology Framework (Pedersen & Revenson, 2005), this study examined differences in two proposed psychological components of role-redistribution (youth caregiving experiences and responsibilities) between youth of a parent with illness and their peers from ‘healthy’ families controlling for the effects of whether a parent is ill or some other family member, illness type, and demographics. Based on self-report questionnaire data, four groups of Australian children were derived from a community sample of 2474youth (‘healthy’ family, n=1768; parental illness, n=336; other family member illness, n=254; both parental and other family member illness, n=116). The presence of any family member with a serious illness is associated with an intensification of youth caregiving experiences relative to peers from healthy families. This risk is elevated if the ill family member is a parent, if more illnesses are present, and by certain youth and family demographics, and especially by higher caregiving responsibilities. The presence of a family member, particularly a parent, with a serious medical condition has pervasive increased effects on youth caregiving compared to healthy families, and these effects are not fully accounted for by illness type, demographics or caregiving responsibilities.

Students’ perceptions of their own victimization: A youth voice perspective

This article investigates the perceptions of 156 students who were victims of both traditional and cyberbullying (117 female, 45 male), ages 10 to 17 years, as to which form of bullying was more hurtful. Overall, students perceived traditional victimization to be more hurtful than cyber victimization. Reasons identified in the data to explain the different perceptions of victims were categorized and found to relate to: the bully, the bystanders, the bullying incidents, the emotional impact on the victim, and the victim’s ability to respond. The perceptions of these students challenge a number of suppositions presented in the literature that attempt to explain why cyberbullying is associated with more negative outcomes than traditional bullying. The implications for antibullying programs to address these issues are discussed.

Regressive measures won’t help youth into work or training

The 2014 federal budget implemented a so-called crackdown on what Minister for Social Services Kevin Andrews calls young people who are content to “sit on the couch at home and pick up a welfare cheque”. The crackdown will change access to income support for people under 30 years of age. From January 1 2015, all young people seeking Newstart Allowance and Youth Allowance for the first time will be required to “demonstrate appropriate job search and participation in employment services support for six months before receiving payments”. Upon qualifying, recipients must then spend 25 hours per week in Work for the Dole in order to receive income support for a six-month period. What happens beyond this six months is unclear. What is clear is that these policy changes, together with the Minister’s accompanying statements, are informed by a deficit view of disadvantaged youth. It is a view that demonstrates how little politicians know or understand about these young peoples’ past circumstances.

Unspeakably present: The (un)acknowledgment of diverse sexuality and gender human rights in Australian youth justice systems

A number of international human rights frameworks protect the rights of young people in contact with the criminal justice system in states parties, including Australia. These frameworks inform youth justice policy in Australia’s jurisdictions. While the frameworks protect young people’s right to non-discrimination on the grounds of ‘race’, religion and political opinion, the rights of young people to non-discrimination on the grounds of sexuality and gender diversity are not explicitly protected. This is problematic given that lesbian, gay, bisexual, trans, intersex and queer (LGBTIQ) young people appear over-represented in youth justice systems. This article argues that the exclusion of this group from human rights frameworks has an important flow-on effect: the marginalisation of the right of LGBTIQ young people to non-discrimination in policy and discourse that is informed by international human rights frameworks. After outlining the relevant frameworks, this article examines the evidence about LGBTIQ young people’s interactions with youth justice agencies, particularly police. The evidence indicates that the human rights of LGBTIQ young people are frequently breached in these interactions. We conclude by arguing that it is timely to consider how best to protect the human rights of LBGTIQ young people and keep their rights on the agenda.

Examining the effectiveness of Police-Citizens Youth Clubs on crime prevention and community safety

PCYCs, individually and as a whole, are highly valued in communities across Queensland. Participants in this evaluation identified numerous benefits of PCYCs, including: providing structured low-cost activities for young people and other community groups; developing positive relationships and trust between young people and police; developing young people into effective citizens; providing a safe place for young people and a hub for whole communities; addressing disadvantages faced by young people; and fostering social inclusion. Depending on the particular activities and programs delivered by a branch, PCYCs have the capacity to minimise risk factors and enhance protective factors relating to young people’s involvement in crime. For example, PCYCs can play an important role in strengthening young people’s engagement with education and family. However, the crime prevention and community safety aims of PCYCs, and measures that might work towards these aims are not widely- or well-understood, or appreciated, by those working in and with PCYCs. The key recommendation of this evaluation is therefore that the crime prevention and community safety aims of PCYCs in Queensland need to be better articulated, understood and reflected in the practice of those working in and with PCYCs. A related key finding is that many of the activities and programs currently provided by PCYCs could be better oriented towards the goals of crime prevention and community safety without major resource implications.

Barriers to entering affordable home ownership for young people: A preliminary study from university students’ perspectives

Over the last two decades, housing affordability has been a problem for young people, and identified as factor leading to youth homelessness. The National Youth Commission Inquiry into Youth Homelessness developed a roadmap for preventing this problem (National Youth Commission, 2008). The roadmap recommends increasing the supply of affordable housing for young people as an important strategy to reduce the risk of homelessness problems. In addition, understanding the barriers and the needs of young people is a significant part of the development of a national affordable housing strategy. This paper explores issues encountered by young people when they enter the housing market as first home buyers. A short survey was conducted to review the barriers to entry, classified by income levels, housing cost and availability of affordable housing. In the current competitive job market, young people have minimal work experience, relatively low job security and low income. In addition to these barriers, participants also suggested other barriers towards the purchase of their first home, such as lack of knowledge of legal issues and lack of government funding. This study suggests the need for both government and educational support for young people around housing choices and the development of financial strategies to manage barriers towards owning their first home.

School-based education programmes for the prevention of child sexual abuse

Background Child sexual abuse is a significant global problem in both magnitude and sequelae. The most widely used primary prevention strategy has been the provision of school-based education programmes. Although programmes have been taught in schools since the 1980s, their effectiveness requires ongoing scrutiny. Objectives To systematically assess evidence of the effectiveness of school-based education programmes for the prevention of child sexual abuse. Specifically, to assess whether: programmes are effective in improving students’ protective behaviours and knowledge about sexual abuse prevention; behaviours and skills are retained over time; and participation results in disclosures of sexual abuse, produces harms, or both. Search methods In September 2014, we searched CENTRAL, OvidMEDLINE, EMBASE and 11 other databases.We also searched two trials registers and screened the reference lists of previous reviews for additional trials. Selection criteria We selected randomised controlled trials (RCTs), cluster-RCTs, and quasi-RCTs of school-based education interventions for the prevention of child sexual abuse compared with another intervention or no intervention. Data collection and analysis Two review authors independently assessed the eligibility of trials for inclusion, extracted data, and assessed risk of bias.We summarised data for six outcomes: protective behaviours; knowledge of sexual abuse or sexual abuse prevention concepts; retention of protective behaviours over time; retention of knowledge over time; harm; and disclosures of sexual abuse.

A new approach to the cloud-based heterogeneous MapReduce placement problem

Guaranteeing Quality of Service (QoS) with minimum computation cost is the most important objective of cloud-based MapReduce computations. Minimizing the total computation cost of cloud-based MapReduce computations is done through MapReduce placement optimization. MapReduce placement optimization approaches can be classified into two categories: homogeneous MapReduce placement optimization and heterogeneous MapReduce placement optimization. It is generally believed that heterogeneous MapReduce placement optimization is more effective than homogeneous MapReduce placement optimization in reducing the total running cost of cloud-based MapReduce computations. This paper proposes a new approach to the heterogeneous MapReduce placement optimization problem. In this new approach, the heterogeneous MapReduce placement optimization problem is transformed into a constrained combinatorial optimization problem and is solved by an innovative constructive algorithm. Experimental results show that the running cost of the cloud-based MapReduce computation platform using this new approach is 24:3%-44:0% lower than that using the most popular homogeneous MapReduce placement approach, and 2:0%-36:2% lower than that using the heterogeneous MapReduce placement approach not considering the spare resources from the existing MapReduce computations. The experimental results have also demonstrated the good scalability of this new approach.

The challenge of normative influences for program design for youth in detention

Young people in detention are at greater risk of death and disability from injury sustained while not in custody. Injury prevention and mental health programs have been designed for this group but their theoretical basis is rarely discussed. The present study investigates whether the conceptual basis of the Theory of Planned Behavior (TPB) is relevant to youth in a detention center. Focus group and observational data were collected. A thematic analysis supported central theoretical constructs and emphasized “Subjective Norms.” The challenge of normative influences must be actively addressed in the design of health interventions for youth in detention.

Queer Youth Research/ers: A reflexive account of risk and intimacy in an ethical (mine)field

In contemporary Western societies, the years between childhood and young adulthood are commonly understood to be (trans)formative in the reflexive project of sexual self-making (Russell et al. 2012). As sexual subjects in the making, youthful bodies, desires and sexual activities are often perceived as both volatile and vulnerable, thus subjected to instruction and discipline, protection and surveillance. Accordingly, young people’s sexual proximities are closely monitored by social institutions and ‘(hetero)normalising regimes’ (Warner 1999) for any signs that may compromise the end goal of development—a ‘normal’ reproductive heterosexual monogamous adult.
