Aim To identify key predictors and moderators of mental health ‘help-seeking behavior’ in adolescents. Background Mental illness is highly prevalent in adolescents and young adults; however, individuals in this demographic group are among the least likely to seek help for such illnesses. Very little quantitative research has examined predictors of help-seeking behaviour in this demographic group. Design A cross-sectional design was used. Methods A group of 180 volunteers between the ages of 17–25 completed a survey designed to measure hypothesized predictors and moderators of help-seeking behaviour. Predictors included a range of health beliefs, personality traits and attitudes. Data were collected in August 2010 and were analysed using two standard and three hierarchical multiple regression analyses. Findings The standard multiple regression analyses revealed that extraversion, perceived benefits of seeking help, perceived barriers to seeking help and social support were direct predictors of help-seeking behaviour. Tests of moderated relationships (using hierarchical multiple regression analyses) indicated that perceived benefits were more important than barriers in predicting help-seeking behaviour. In addition, perceived susceptibility did not predict help-seeking behaviour unless individuals were health conscious to begin with or they believed that they would benefit from help. Conclusion A range of personality traits, attitudes and health beliefs can predict help-seeking behaviour for mental health problems in adolescents. The variable ‘Perceived Benefits’ is of particular importance as it is: (1) a strong and robust predictor of help-seeking behaviour, and; (2) a factor that can theoretically be modified based on health promotion programmes.

Information Technology (IT) value is amongst the most important concepts in the Information Systems (IS) research field. Yet, a clear, well-formulated conceptualization of IT value, cumulatively built upon, is lacking. Drawing from the Facet Theory literature, this paper broaches several meta-theoretical considerations addressing an “ideal” conceptualization of IT value. We argue these considerations may shed light on the advancement of IT value conceptualization methodology.

This article discusses the design of interactive online activities that introduce problem solving skills to first year law students. They are structured around the narrative framework of ‘Ruby’s Music Festival’ where a young business entrepreneur encounters various issues when organising a music festival and students use a generic problem solving method to provide legal solutions. These online activities offer students the opportunity to obtain early formative feedback on their legal problem solving abilities prior to undertaking a later summative assessment task. The design of the activities around the Ruby narrative framework and the benefits of providing students with early formative feedback will be discussed.

Although seeking help for mental ill-health is beneficial, the majority of persons afflicted do not access available help services. Young adults (16-24 years old) in particular have the highest prevalence of mental health problems and the lowest rate of help-seeking behaviour. Key barriers to help-seeking for young adults, including cost, privacy concerns, inconvenience, access to health professionals and interpersonal interaction, appear to derive from the face-to-face method of service delivery traditionally used to distribute mental health services. Social marketing employs the principle of value exchange, whereby consumers will choose a behaviour in exchange for receiving valued benefits and/or a reduction in key barriers, to achieve behavioural goals for social good. The appropriation of mobile digital technology to deliver self-help mental health services may reduce the current barriers to help seeking, however, extant literature offers no empirical support for this proposition. Our research addresses this gap by examining the perceptions of young adults regarding M-mental health services. Depth interviews were undertaken with 15 young adults (18-24 years old), who had self-reported mild-moderate stress, anxiety or depression. The data were thematically analysed with the assistance of Nvivo. The findings reveal M-mental health services reduce the barriers to accessing face-to-face help services to a large extent. However, they also present their own barriers to help-seeking that must be considered by social marketers, including negligible cost expectations and service efficacy concerns. Overall, this study highlights the potential of M-mental health services to encourage early intervention and help-seeking behaviour as part of a social marketing strategy to address mental illness in young adults.

The present study deals with two dimensional, numerical simulation of railway track supporting system subjected to dynamic excitation force. Under plane strain condition, the coupled finite-infinite elements to represent the near and far field stress distribution and thin layer interface element was employed to model the interfacial behavior between sleepers and ballast. To account for the relative debonding, slipping and crushing that could take place in the contact area between the sleepers and ballast, modified Mohr-Coulomb criterion was adopted. Furthermore an attempt has been made to consider the elasto-plastic material non-linearity of the railway track supporting media by employing different constitutive models to represent steel, concrete and supporting materials. Based on the proposed physical and constitutive modeling a code has been developed for dynamic loads. The applicability of the developed F.E code has been demonstrated by analyzing a real railway supporting structure.

The STIMulate program provides support for learning across maths, science and IT to QUT coursework students. The program has good traction with the diverse QUT student community, with a focus on helping students in threshold skills and concepts across discipline areas. Students who attend learning support programs generally speak highly of these services. However, staff commonly report that many of the students most in need fail to access support. At the end of 2014, we sought feedback from non-users of STIMulate to investigate why they didn’t use the program. Of the 223 respondents, 34% of students had not used STIMulate services. These students were asked why they had not used STIMulate, and what would encourage them to attend STIMulate services. Based on student responses, issues that would encourage students to attend STIMulate can be classified into 6 key areas: marketing, timing, mode, belonging, need and space. These issues are then addressed through actionable recommendations to better enable future students to utilise the STIMulate program.

Unsteady natural convection flow in a two- dimensional square cavity filled with a porous material has been studied. The flow is initially steady where the left- hand vertical wall has temperature T-h and the right- hand vertical wall is maintained at temperature T-c ( T-h > T-c) and the horizontal walls are insulated. At time t > 0, the left- hand vertical wall temperature is suddenly raised to (T-h) over bar ((T-h) over bar > T-h) which introduces unsteadiness in the flow field. The partial differential equations governing the unsteady natural convection flow have been solved numerically using a finite control volume method. The computation has been carried out until the final steady state is reached. It is found that the average Nusselt number attains a minimum during the transient period and that the time required to reach the final steady state is longer for low Rayleigh number and shorter for high Rayleigh number.

The imperative for Indigenous education in Australia is influenced by national political, social and economic discourses as Australian education systems continue to grapple with an agreed aspiration of full participation for Aboriginal and Torres Strait Islander students. Innovations within and policies guiding our education systems are often driven by agendas of reconciliation, equity, equality in participation and social justice. In this paper, we discuss key themes that emerged from a recent Australian Office for Learning and Teaching (OLT) research project which investigated ways in which preservice teachers from one Australian university embedded Indigenous knowledges (IK) on teaching practicum . Using a phenomenological approach, the case involved 25 preservice teacher and 23 practicum supervisor participants, over a 30 month investigation. Attention was directed to the nature of subjective (lived) experiences of participants in these pedagogical negotiations and thus preservice and supervising teacher voice was actively sought in naming and analysing these experiences. Findings revealed that change, knowledge, help and affirmation were key themes for shaping discourses around Indigenous knowledges and perspectives in the Australian curriculum and defined the nature of the pedagogical relationships between novice and experienced teachers. We focus particularly on the need for change and affirmation by preservice teachers and their teaching practicum supervisors as they developed their pedagogical relationships whilst embedding Indigenous knowledges in learning and teaching.

This qualitative study investigated the refugee journey of 17 males who arrived in Australia as unaccompanied asylum-seeking minors between 2009 and 2013, and were granted protection visas. The paper focuses on the four conceptual challenges of refugee journeys, as identified recently by BenEzer and Zetter: temporal characteristics; drivers and destinations; the process/content of the journey; and the characteristics of the wayfarers. The findings indicate that their mental journey has not yet ended and transcends the physical departure-arrival voyage. Although the primary drivers for the refugee journey were protection reasons, their desire to find a “better life” free from violence and exclusion also played an important role. The irregular character of the journey made it highly unpredictable, exposed these minors to extreme levels of vulnerability and the need to remain invisible, prompted short lived friendships with other asylum seekers, and created a pervasive feeling of mistrust towards smugglers and other people they met along the way. The study has highlighted the need for interventions to protect unaccompanied minors during their refugee journey.

The purpose of this study was to extend understanding of how large firms pursuing sustained and profitable growth manage organisational renewal. A multiple-case study was conducted in 27 North American and European wood-industry companies, of which 11 were chosen for closer study. The study combined the organisational-capabilities approach to strategic management with corporate-entrepreneurship thinking. It charted the further development of an identification and classification system for capabilities comprising three dimensions: (i) the dynamism between firm-specific and industry-significant capabilities, (ii) hierarchies of capabilities and capability portfolios, and (iii) their internal structure. Capability building was analysed in the context of the organisational design, the technological systems and the type of resource-bundling process (creating new vs. entrenching existing capabilities). The thesis describes the current capability portfolios and the organisational changes in the case companies. It also clarifies the mechanisms through which companies can influence the balance between knowledge search and the efficiency of knowledge transfer and integration in their daily business activities, and consequently the diversity of their capability portfolio and the breadth and novelty of their product/service range. The largest wood-industry companies of today must develop a seemingly dual strategic focus: they have to combine leading-edge, innovative solutions with cost-efficient, large-scale production. The use of modern technology in production was no longer a primary source of competitiveness in the case companies, but rather belonged to the portfolio of basic capabilities. Knowledge and information management had become an industry imperative, on a par with cost effectiveness. Yet, during the period of this research, the case companies were better in supporting growth in volume of the existing activity than growth through new economic activities. Customer-driven, incremental innovation was preferred over firm-driven innovation through experimentation. The three main constraints on organisational renewal were the lack of slack resources, the aim for lean, centralised designs, and the inward-bound communication climate.

Austria and Finland are persistently referred to as the “success stories” of post-1945 European history. Notwithstanding their different points of departure, in the course of the Cold War both countries portrayed themselves as small and neutral border-states in the world dictated by superpower politics. By the 1970s, both countries frequently ranked at the top end in various international classifications regarding economic development and well-being in society. This trend continues today. The study takes under scrutiny the concept of consensus which figures centrally in the two national narratives of post-1945 success. Given that the two domestic contexts as such only share few direct links with one another and are more obviously different than similar in terms of their geographical location, historical experiences and politico-cultural traditions, the analogies and variations in the anatomies of the post-1945 “cultures of consensus” provide an interesting topic for a historical comparative and cross-national examination. The main research question concerns the identification and analysis of the conceptual and procedural convergence points of the concepts of the state and consensus. The thesis is divided into six main chapters. After the introduction, the second chapter presents the theoretical framework in more detail by focusing on the key concepts of the study – the state and consensus. Chapter two also introduces the comparative historical and cross-national research angles. Chapter three grounds the key concepts of the state and consensus in the historical contexts of Austria and Finland by discussing the state, the nation and democracy in a longer term comparative perspective. The fourth and fifth chapter present case studies on the two policy fields, the “pillars”, upon which the post-1945 Austrian and Finnish cultures of consensus are argued to have rested. Chapter four deals with neo-corporatist features in the economic policy making and chapter five discusses the building up of domestic consensus regarding the key concepts of neutrality policies in the 1950s and 1960s. The study concludes that it was not consensus as such but the strikingly intense preoccupation with the theme of domestic consensus that cross-cut, in a curiously analogous manner, the policy-making processes studied. The main challenge for the post-1945 architects of Austrian and Finnish cultures of consensus was to find strategies and concepts for consensus-building which would be compatible with the principles of democracy. Discussed at the level of procedures, the most important finding of the study concerns the triangular mechanism of coordination, consultation and cooperation that set into motion and facilitated a new type of search for consensus in both post-war societies. In this triangle, the agency of the state was central, though in varying ways. The new conceptions concerning a small state’s position in the Cold War world also prompted cross-nationally perceivable willingness to reconsider inherited concepts and procedures of the state and the nation. At the same time, the ways of understanding the role of the state and its relation to society remained profoundly different in Austria and Finland and this basic difference was in many ways reflected in the concepts and procedures deployed in the search for consensus and management of domestic conflicts.
