The first time delivery of the first link learning series using Skype and YouTube

Introduction: This case study documented the experiences of informal and service providers who participated in the first time delivery of the First Link Learning Series from May–August 2013 in Newfoundland and Labrador. The aim of this study was to understand how informal caregivers of people with dementia experience this Internet mediated health resource, and how Skype and YouTube can be used as tools for the Alzheimer Society of Newfoundland and Labrador to effectively deliver the First Link Learning Series. Methods: Sources of data included key informant interviews (n=3), pre- study and post-study interviews with informal dementia caregivers (n=2), institutional documentation, field notes, and YouTube analytics. Framework Analysis was used to make meaning of the qualitative data, and descriptive statistics were used to report on quantitative outcomes. Findings: Between 3% and 17% of registered First Link clients attended the learning series sessions, however only two caregivers participated using Skype or YouTube. Framework Analysis revealed three shared themes: access, connection and privacy. Discussion: The themes helped to begin building theory about barriers and facilitators to Internet mediated health resources for informal dementia caregivers. Experiences of service providers using the Internet to support clients served to begin building a case for the appropriateness of these media. A modified version of Dansky et al.’s (2006) theoretical framework for evaluating E-Health research that situates the person/user in the model, helped guide discussion and propose future directions for the study of Internet based health resources for informal dementia caregivers.

The "Sensory Deprivation Tank": an interpretative phenomenological analysis of men's expectations of first-time fatherhood

Few studies have investigated expectations of fatherhood in men without children, and none within the age bracket most often associated with new fatherhood. Therefore, the objective of this qualitative study was to gain in-depth understanding of young men's beliefs and perceptions of that role. Interpretative Phenomenological Analysis (IPA) of interview transcripts identified 3 key themes: The contemporary model father, perceived threat to life as we know it, and, the central theme, an unforeseeable future. Analysis revealed that while participants held broad expectations to be emotionally and physically involved as well as economically responsible fathers, their views often lacked specificity, consideration of meaning, and practical notions about how expectations could be fulfilled. We explain the lack of development in men's conceptualization of fatherhood across emerging adulthood through hegemonic masculinity, identity theory, and life course perspectives. The current study provides a rationale for promoting increased discussion around fatherhood in the preconception period to help lessen the turbulent nature of men's transition through pregnancy.

La détermination d’un sous-groupe de contrevenants de la conduite avec capacités affaiblies à risque élevé de récidive : l’utilité de l’axe hypothalamo-hypophyso-surrénalien

Les contrevenants de la conduite avec capacités affaiblies (CCA) n’entrent pas tous dans les registres de la sécurité routière avec le même risque de récidive. Pour pallier cette hétérogénéité, cette thèse propose de modéliser les interrelations entre les traits de personnalité et les comportements à risque associés à la récidive et de détecter un sous-groupe de contrevenants au risque de récidive élevé à l’aide de l’axe hypothalamo-hypophyso-surrénalien (HHS). Plus particulièrement, les trois articles de cette thèse s’intéressent au cortisol, l’hormone du stress. Le premier article élabore un modèle théorique réconciliant les connaissances sur l’axe HHS issues du domaine de la CCA et de domaines connexes. Lors de précédentes études, le nombre de condamnations antérieures pour CCA a été associé négativement à la réactivité du cortisol à la suite d’une situation stressante. Chez les récidivistes, cette faible réactivité s’explique partiellement par la recherche d’expériences, une dimension de la recherche de sensations. Au-delà ce trait de personnalité désinhibiteur, une faible activité de l’axe HHS a été associée à d’autres traits (c.-à-d. impulsivité et tendances antisociales) et d’autres comportements à risque (c.-à-d. infractions routières, arrestations criminelles et consommation problématique de substances psychoactives). Ce modèle intégrant la réactivité du cortisol permet une conceptualisation approfondie des diverses caractéristiques des contrevenants de la CCA et explique hypothétiquement la répétition des comportements à risque. Les deux articles suivants se penchent sur l’intérêt empirique d’utiliser l’axe HHS pour déterminer un sous-groupe de contrevenants à risque élevé de récidive. Plus précisément, le deuxième article émet l’hypothèse que les récidivistes (n = 30) ayant une faible activité de leur cortisol (c.-à-d. médiane de la surface sous la courbe relative au niveau de base et relative à la réactivité) ont davantage de traits de personnalité désinhibiteurs et de comportements à risque que les récidivistes ayant une forte activité. L’hypothèse n’a pas été confirmée. Au contraire, les récidivistes présentant une faible réactivité commettent moins d’infractions routières et d’arrestations criminelles que ceux ayant une forte réactivité. Quant à lui, le troisième article investigue une hypothèse similaire auprès des contrevenants primaires (n = 139). Les contrevenants manifestant une faible réactivité du cortisol (c.-à-d. différence entre prélèvements post-stress et pré-stress) ont davantage d’impulsivité attentionnelle, de non-planification, d’arrestations criminelles et de cigarettes fumées par jour que les contrevenants ayant une forte réactivité. Lors d’analyses exploratoires, la présence d’une variété de traits de personnalité désinhibiteurs et de comportements à risque chez les contrevenants primaires présentant une faible réactivité lorsque comparé au groupe contrôle (n = 31) suggère encore une fois leur risque élevé de récidive. L’intérêt d’ajouter un mécanisme neurobiologique pour modéliser les interrelations entre les traits de personnalité désinhibiteurs et les comportements à risque des contrevenants de la CCA a été exploré dans cette thèse. La détermination d’un sous-groupe de contrevenants présentant un risque élevé de récidive, à l’aide de l’axe HHS, semble davantage profitable auprès de l’hétérogène population des contrevenants primaires. En contrepartie, l’axe HHS ne permet pas de déterminer un sous-groupe ayant une problématique sévère auprès des récidivistes à l’extrême du continuum du risque.

The Steering Clear First Offender Drink Driving Program

This program is a research based, guided intervention program, designed for first time drink driving offenders which provides them with information and strategies to avoid drink driving in the future. It is an innovative program with the ability to tailor specific information to different individuals based on their level of risk of reoffending and help them develop their own plan to prevent them from drink driving. It aims to teach offenders the skills to implement their own plan when they determine they are at risk of future drink driving. The program provides information about: What a standard drink is and how blood alcohol content (BAC) is determined; How alcohol affects the body, reaction time, and decision making; The consequences of drink driving and what happens after a second offence; How to deal with risky drink driving situations in the future; How to build a personalised plan to avoid drink driving in the future, and; Levels of alcohol consumption and its impact on daily life. It also includes access to a mobile friendly web app that can be used anytime after completing the program. This is tool that will aid offenders in tracking their drinks and build on plans to prevent future drink driving.

An innovative online intervention: The Steering Clear First Offender Drink Driving Program

Drink driving remains a substantial public health issue warranting investigation. First offender drink drivers are seen to be less risky than repeat offenders, though the majority of first offenders report drink driving prior to detection, and many continue to drink drive following conviction. Few first offenders are offered treatment programs, and as such there is a need to address drink driving behaviour at this stage. A comprehensive approach including first offender treatment is needed to address the problem. Online interventions have demonstrated effectiveness in reducing risky behaviours such as harmful substance use. Such interventions allow for personalised tailored content to be delivered to individuals targeting specific mechanisms of behavioural change. This method also allows for targeting screening to ensure relevance of content on an individual level. However, there have been no research based online programs to date aimed at reducing repeat drink driving by first offenders. The Steering Clear First Offender Drink Driving Program is a self-guided, research based online program aimed at reducing recidivism by first time drink driving offenders. It includes a specialised web app to track drinks and build plans to prevent future drink driving. This allows for elongation of learning and encouragement of sustained behavioural change using self-monitoring after initial program completion. An outline of the program is discussed and the qualitative experience of the program on a sample of first offenders recruited at the time of court appearance is described.

Who are the real “first offenders”?

Drink driving causes more fatal crashes than any other single factor on Australian roads, with a third of crashes having alcohol as a contributing factor. In recent years there has been a plateau in the numbers of drink drivers apprehended by RBT, and around 12% of the general population in self report surveys admit to drinking and driving. There is limited information about the first offender group, particularly the subgroup of these offenders who admit to prior drink driving, the offence therefore being the “first time caught”. This research focuses on the differences between those who report drink driving prior to apprehension for the offence and those who don’t. Methods: 201 first time drink driving offenders were interviewed at the time of their court appearance. Information was collected on socio-demographic variables, driving behaviour, method of apprehension, offence information, alcohol use and self reported previous drink driving. Results: 78% of respondents reported that they had driven over the legal alcohol limit in the 6 months prior to the offence. Analyses revealed that those offenders who had driven over the limit previously without being caught were more likely to be younger and have an issue with risky drinking. When all variables were taken into account in a multivariate model using logistic regression, only risky drinking emerged as significantly related to past drink driving. High risk drinkers were 4.8 times more likely to report having driven over the limit without being apprehended in the previous 6 months. Conclusion: The majority of first offenders are those who are “first time apprehended” rather than “first time drink drivers”. Having an understanding of the differences between these groups may alter the focus of educational or rehabilitation countermeasures. This research is part of a larger project aiming to target first time apprehended offenders for tailored intervention.

What are the offence and offender risk factors for Indigenous repeat drink drivers in Queensland?

In Australia and internationally, there is scant information about Indigenous repeat drink drivers. The aim was to identify the risk factors associated with repeat offending. De-identified data on drink driving convictions by offenders identifying as Indigenous in Queensland between 2006 and 2010 were examined. A range of univariate analyses were used to compare first time and repeat offenders on gender, age, court location and region (based on the accessibility/remoteness index of Australia), blood alcohol concentration and sentencing severity. Multivariate logistic regression adjusted for confounding variables. Convictions for repeat offenders were more likely from locations other than ‘major cities’ with the association strongest for courts in the ‘very remote’ region (OR=2.75, 2.06-3.76, p<.001). Indigenous offenders 40 years or older were found to be at reduced risk in comparison to offenders aged 15-24 years (OR=0.68, 0.54-0.86, p=0.01). After controlling for confounding factors, gender, sentencing severity and blood alcohol concentration levels were not significantly associated with recidivism. The association of recidivism and remoteness is consistent with higher rates of alcohol-related transport accidents involving Indigenous Australians in isolated areas. This study provides a platform for future research and allows for early attempts to address the need for intervention to reduce Indigenous drink driving recidivism.

First real-time experimental demonstrations of 11.25Gb/s optical OFDMA PONs with adaptive dynamic bandwidth allocation.

End-to-end real-time experimental demonstrations are reported, for the first time, of aggregated 11.25Gb/s over 26.4km standard SMF, optical orthogonal frequency division multiple access (OOFDMA) PONs with adaptive dynamic bandwidth allocation (DBA). The demonstrated intensity-modulation and direct-detection (IMDD) OOFDMA PON system consists of two optical network units (ONUs), each of which employs a DFB-based directly modulated laser (DML) or a VCSEL-based DML for modulating upstream signals. Extensive experimental explorations of dynamic OOFDMA PON system properties are undertaken utilizing identified optimum DML operating conditions. It is shown that, for simultaneously achieving acceptable BERs for all upstream signals, the OOFDMA PON system has a >3dB dynamic ONU launch power variation range, and the BER performance of the system is insusceptible to any upstream symbol offsets slightly smaller than the adopted cyclic prefix. In addition, experimental results also indicate that, in addition to maximizing the aggregated system transmission capacity, adaptive DBA can also effectively reduce imperfections in transmission channel properties without affecting signal bit rates offered to individual ONUs.

Real time detectionof airborne fungal spores and investigations into their dynamics in indoor air

Concern regarding the health effects of indoor air quality has grown in recent years, due to the increased prevalence of many diseases, as well as the fact that many people now spend most of their time indoors. While numerous studies have reported on the dynamics of aerosols indoors, the dynamics of bioaerosols in indoor environments are still poorly understood and very few studies have focused on fungal spore dynamics in indoor environments. Consequently, this work investigated the dynamics of fungal spores in indoor air, including fungal spore release and deposition, as well as investigating the mechanisms involved in the fungal spore fragmentation process. In relation to the investigation of fungal spore dynamics, it was found that the deposition rates of the bioaerosols (fungal propagules) were in the same range as the deposition rates of nonbiological particles and that they were a function of their aerodynamic diameters. It was also found that fungal particle deposition rates increased with increasing ventilation rates. These results (which are reported for the first time) are important for developing an understanding of the dynamics of fungal spores in the air. In relation to the process of fungal spore fragmentation, important information was generated concerning the airborne dynamics of the spores, as well as the part/s of the fungi which undergo fragmentation. The results obtained from these investigations into the dynamics of fungal propagules in indoor air significantly advance knowledge about the fate of fungal propagules in indoor air, as well as their deposition in the respiratory tract. The need to develop an advanced, real-time method for monitoring bioaerosols has become increasingly important in recent years, particularly as a result of the increased threat from biological weapons and bioterrorism. However, to date, the Ultraviolet Aerodynamic Particle Sizer (UVAPS, Model 3312, TSI, St Paul, MN) is the only commercially available instrument capable of monitoring and measuring viable airborne micro-organisms in real-time. Therefore (for the first time), this work also investigated the ability of the UVAPS to measure and characterise fungal spores in indoor air. The UVAPS was found to be sufficiently sensitive for detecting and measuring fungal propagules. Based on fungal spore size distributions, together with fluorescent percentages and intensities, it was also found to be capable of discriminating between two fungal spore species, under controlled laboratory conditions. In the field, however, it would not be possible to use the UVAPS to differentiate between different fungal spore species because the different micro-organisms present in the air may not only vary in age, but may have also been subjected to different environmental conditions. In addition, while the real-time UVAPS was found to be a good tool for the investigation of fungal particles under controlled conditions, it was not found to be selective for bioaerosols only (as per design specifications). In conclusion, the UVAPS is not recommended for use in the direct measurement of airborne viable bioaerosols in the field, including fungal particles, and further investigations into the nature of the micro-organisms, the UVAPS itself and/or its use in conjunction with other conventional biosamplers, are necessary in order to obtain more realistic results. Overall, the results obtained from this work on airborne fungal particle dynamics will contribute towards improving the detection capabilities of the UVAPS, so that it is capable of selectively monitoring and measuring bioaerosols, for which it was originally designed. This work will assist in finding and/or improving other technologies capable of the real-time monitoring of bioaerosols. The knowledge obtained from this work will also be of benefit in various other bioaerosol applications, such as understanding the transport of bioaerosols indoors.

Are there any true adult-onset offenders?

In the extant literature, adult-onset offending has usually been identified using official sources. It is possible, however, that many of the individuals identified would have had unofficial histories of prior offending. To investigate this issue, the men from the Cambridge Study in Delinquent Development (CSDD) were examined. The CSDD is a prospective longitudinal study of men from inner-city London, followed from age 8 to age 48. Onset of offending was identified using official records and then the self-reported offending of the adult-onset offender group (with a first conviction at age 21 or later) was compared to others. All the adult-onset offenders self-reported some previous offending in childhood and adolescence but most of this offending was not sufficiently frequent or serious to lead to a conviction in practice. About one-third of adult-onset offenders were considered to be self-reported delinquents who were realistically in danger of being convicted because of the frequency of their offending. For some, the adjudication by the criminal justice system was simply the first time that their ongoing pattern of offending had been detected. Their lack of detection was because the types of offences they were committing had lower detection rates.

The First Steps Program : a case study of a new model of community child health service

Community Child Health Nursing Services provide support for new mothers; however, the focus has often been on individual consultations, complemented by a series of group sessions soon after birth. We describe a new model of community care for first-time mothers that centres on group sessions throughout the whole contact period. The model was developed by practicing child health nurses for a large health service district in south-east Queensland, which offers a comprehensive community child health service. Issues identified by clinicians working within existing services, feedback from clients and the need for more resource-efficient methods of service provision underpinned the development of the model. The pilot program was implemented in two community child health centres in Brisbane. An early individual consultation to engage the family with the service was added in response to feedback from clinicians and clients. The modified model has since been implemented service-wide as the ‘First Steps Program’. The introduction of this model has ensured that the service has been able to retain a comprehensive service for first-time parents from a universal population, while responding to the challenges of population growth and the increasing number of complex clients placing demands on resources.

Indigenous knowledges : informing and supporting Indigenous students during their first year at university

This paper critically examines dominant discourses informing First Year Experience programs delivered for Aboriginal and Torres Strait Islander students participating in higher education. We interrogate traditional ‘deficit models’ through the recognition and acknowledgement of Indigenous knowledge at the cultural interface, the arena in which Aboriginal and Torres Strait Islander students encounter university for the first time. In this paper, we demonstrate how the First Year Experience programs for Indigenous students, developed and delivered by the Oodgeroo Unit, are conceptualised by Indigenous knowledges. By recognising Indigenous knowledges and experiences, and valuing these within the Western academy, we provide an alternative to these dominant mainstream discourses and perspectives for Indigenous students navigating their way through university. We argue that Indigenous standpoints provide tools through which Indigenous students can negotiate the cultural interface that exists within the university environment.

Drink driving after the first offence: Characteristics of offenders who continue to drink and drive

Drink driving remains a significant problem on Australian roads, with about a quarter to a third of fatal crashes involving drivers or riders who have a BAC of 0.05 or greater. Last available data in the state of Queensland (2003) of the major factors involved in road fatalities and injuries indicated that alcohol and drugs were noted as one of the contributing factors in 38% of fatalities and 11% of all crashes, making it the highest single contributing factor to road fatalities. Until this point, there has been little information about first time offenders as a group, but it is known that offenders typically are not first time drink drivers but rather ‘first time apprehended’, in that most have engaged in drink driving in the years leading to the first offence. This paper follows 89 first time drink driving offenders who were interviewed at the time of court mention and followed up around 6 months following the court hearing. Of the offenders, 27% reported to have driven over the limit in the time between initial contact and follow up. The paper demonstrates the characteristics and offending patterns of first offenders who engaged in drink driving following conviction and those who didn’t, providing suggestions on how to target those at high risk for the behaviour and subsequent offending.

A first stage test of Dunning's framework on multinational contracting into Australia : reviewing secondary data.

In response to the need to leverage private finance and the lack of competition in some parts of the Australian public sector infrastructure market, especially in the very large economic infrastructure sector procured using Pubic Private Partnerships, the Australian Federal government has demonstrated its desire to attract new sources of in-bound foreign direct investment (FDI). This paper aims to report on progress towards an investigation into the determinants of multinational contractors’ willingness to bid for Australian public sector major infrastructure projects. This research deploys Dunning’s eclectic theory for the first time in terms of in-bound FDI by multinational contractors into Australia. Elsewhere, the authors have developed Dunning’s principal hypothesis to suit the context of this research and to address a weakness arising in this hypothesis that is based on a nominal approach to the factors in Dunning's eclectic framework and which fails to speak to the relative explanatory power of these factors. In this paper, a first stage test of the authors' development of Dunning's hypothesis is presented by way of an initial review of secondary data vis-à-vis the selected sector (roads and bridges) in Australia (as the host location) and with respect to four selected home countries (China; Japan; Spain; and US). In doing so, the next stage in the research method concerning sampling and case studies is also further developed and described in this paper. In conclusion, the extent to which the initial review of secondary data suggests the relative importance of the factors in the eclectic framework is considered. It is noted that more robust conclusions are expected following the future planned stages of the research including primary data from the case studies and a global survey of the world’s largest contractors and which is briefly previewed. Finally, and beyond theoretical contributions expected from the overall approach taken to developing and testing Dunning’s framework, other expected contributions concerning research method and practical implications are mentioned.
