Double standards in special medical research : questioning the discrepancy between requirements for medical research involving incompetent adults and medical research involving children

Medical research represents a substantial departure from conventional medical care. Medical care is patient-orientated, with decisions based on the best interests and/or wishes of the person receiving the care. In contrast, medical research is future-directed. Primarily it aims to contribute new knowledge about illness or disease, or new knowledge about interventions, such as drugs, that impact upon some human condition. Current State and Territory laws and research ethics guidelines in Australia relating to the review of medical research appropriately acknowledge that the functions of medical care and medical research differ. Prior to a medical research project commencing, the study must be reviewed and approved by a Human Research Ethics Committee (HREC). For medical research involving incompetent adults, some jurisdictions require an additional, independent safeguard by way of tribunal or court approval of medical research protocols. This extra review process reflects the uncertainty of medical research involvement, and the difficulties surrogate decision-makers of incompetent adults face in making decisions about others, and deliberating about the risks and benefits of research involvement. Parents of children also face the same difficulties when making decisions about their child’s research involvement. However, unlike the position concerning incompetent adults, there are no similar safeguards under Australian law in relation to the approval of medical research involving children. This column questions why this discrepancy exists with a view to generating further dialogue on the topic.

'I want to educate school age children' : producing early childhood teacher professional identities

The Australian Government’s current workforce reforms in early childhood education and care (ECEC) include a major shift in qualification requirements. The new requirement is that university four-year degree-qualified teachers are employed in before-school contexts, including child care. Ironically, recent research studies show that, in Australia, the very preservice teachers who are enrolled in these degree programs have a reluctance to work in childcare. This article reports on part of a larger study which is inquiring into how early childhood teacher professional identities are discursively produced, and provides a partial mapping of the literature. One preservice teacher’s comment provides the starting point, and the paper locates some the discourses that are accessible to preservice teachers as they prepare for the early years workforce. An awareness of the discursive field provides a sound background for preparing early childhood teachers. A challenge for the field is to consider which discourses are dominant, and how they potentially work to privilege work in some ECEC contexts over others.

(De)Constructing ADHD : Critical Guidance for Teachers and Teacher Educators

Attention Deficit Hyperactivity Disorder (ADHD) has achieved celebrity status in many Western countries, yet despite considerable effort to prove its existence as a “real” disorder, ADHD still suffers from a crisis of legitimacy. Nonetheless, diagnosis and prescription of medication has grown at a phenomenal rate since the late 1980s, particularly in Western culture. Numerous accounts exist explaining how the ADHD diagnosis functions as a convenient administrative loophole, providing schools with a medical explanation for school failure, medication to sedate the “problem” into submission, or the means to eject children from mainstream classrooms. This book provides a more holistic interpretation of how to respond to children who might otherwise be diagnosed with and medicated for “ADHD”—a diagnosis which, whether scientifically valid or not, is unhelpful within the confine of the school. Training teachers to recognise and identify “ADHD symptoms” or to understand the functions of restricted pharmaceuticals will only serve to increase the number of children diagnosed and the sale of psychoactive medications. Research has shown that such activities will not help those children learn, nor will it empower their classroom teachers to take responsibility for teaching such children well. This book seeks to provide school practitioners with knowledge that is useful within the educational context to improve the educational experiences and outcomes for children who might otherwise receive a diagnosis of ADHD.

Countering the Attention Deficit Hyperactivity Disorder epidemic: a question of ethics?

Recently in Australia, another media skirmish has erupted over the problem we currently call “Attention Deficit Hyperactivity Disorder”. This particular event was precipitated by the comments of a respected District Court judge. His claim that doctors are creating a generation of violent juvenile offenders by prescribing Ritalin to young children created a great deal of excitement, attracting the attention of election-conscious politicians who appear blissfully unaware of the role played by educational policy in creating and maintaining the problem. Given the short (election-driven) attention span of government policymakers, I bypass government to question what those at the front line can do to circumvent the questionable practice of diagnosing and medicating young children for difficulties they experience in schools and with learning.

An ontology-based method for sparsity problem in tag recommendation

Tags or personal metadata for annotating web resources have been widely adopted in Web 2.0 sites. However, as tags are freely chosen by users, the vocabularies are diverse, ambiguous and sometimes only meaningful to individuals. Tag recommenders may assist users during tagging process. Its objective is to suggest relevant tags to use as well as to help consolidating vocabulary in the systems. In this paper we discuss our approach for providing personalized tag recommendation by making use of existing domain ontology generated from folksonomy. Specifically we evaluated the approach in sparse situation. The evaluation shows that the proposed ontology-based method has improved the accuracy of tag recommendation in this situation.

A combined method for mitigating sparsity problem in tag recommendation

Tag recommendation is a specific recommendation task for recommending metadata (tag) for a web resource (item) during user annotation process. In this context, sparsity problem refers to situation where tags need to be produced for items with few annotations or for user who tags few items. Most of the state of the art approaches in tag recommendation are rarely evaluated or perform poorly under this situation. This paper presents a combined method for mitigating sparsity problem in tag recommendation by mainly expanding and ranking candidate tags based on similar items’ tags and existing tag ontology. We evaluated the approach on two public social bookmarking datasets. The experiment results show better accuracy for recommendation in sparsity situation over several state of the art methods.

The journey of becoming involved : the experience of participation in urban spaces by children with diverse mobility

Despite considerable discussion regarding the virtues of participation in urban spaces, the urban experience of children with disabilities has been largely ignored. This intensive study reported on the everyday experience of urban participation on the part of children with conditions such as cerebral palsy, muscular dystrophy, and juvenile arthritis, contributing new insights into their experience of journeys central to becoming involved in settings such as schools, neighbourhoods and shopping centres. The study identified problems in body – space – context relationships as points of intervention in our urban settings that promise to make a significant difference to their everyday journeys.

Alveolar dose comparison of ultrafine particles for Australian and Italian children

Epidemiological studies have demonstrated that exposure to particulate air pollution is associated with several adverse health effects. Recently, interest has focused on ultrafine particles (UFPs, diameter ≤ 100 nm), due to the adverse health effects caused by their ability to induce inflammation and deposit in secondary organs [1]. These effects are much more pronounced in children because they inhale a higher dose of UFPs relative to both lung size (when compared with adults) [2] and increased breathing rates, since they are generally more physically active than adults ...

Alveolar dose of ultrafine particles for children in urban environments

The aim of this study was to quantify school children���s exposure to ultrafine particles (UFP) in urban environments. The study was conducted as part of a larger epidemiological project aiming to determine the association between exposures to UFPs and children���s health, titled “Ultrafine Particles from Traffic Emissions and Children���s Health”1 (UPTECH). School children aged 8-11 years old at 24 state schools within the Brisbane Metropolitan Area participated in the present study. This paper presents the methodology and results for calculating deposited UFP surface area in the alveolar region (dose), where UFP deposition is more efficient for particles larger than 6 nm...

Postdiagnosis personal growth in an Australian population of parents raising children with developmental disability

Background Parenting a child with a developmental disability presents a variety of long-term physical and emotional challenges. When exploring parent wellbeing, the disability field is dominated by a deficit model despite parents reportedly demonstrating coping and resilience. The current study is embedded in a salutogenic theory (Antonovsky, 1979) and explores the potential for parents of children diagnosed with a developmental disability to undergo positive changes. Method Participants were 6 fathers and 27 mothers who completed measures of distress and posttraumatic growth. Results Compared with a number of other Australian samples, participants reported significantly higher levels of posttraumatic growth. Reports of growth did not negate reports of distress. Results also indicated that constructs of distress and growth were independent. Conclusions The research has important implications for disability support services, reminding providers to be cognisant of the potential for growth, as well as distress, thereby permitting an atmosphere conducive to exploring such outcomes.

Secrets, Lies and Children's Fiction

Many children learn from a very young age about the importance of always telling the truth. They also learn that telling lies is necessary if they are to survive in a world that paradoxically values the truth but practises deception. Secrets, Lies and Children���s Fiction demonstrates how this paradox is played out in texts for children and young adults, how secrets and lies may be a necessary means for survival and adaptation, and how mendacity may have its virtues.

The effect of surface tension and kinetic undercooling on a radially-symmetric melting problem

The addition of surface tension to the classical Stefan problem for melting a sphere causes the solution to blow up at a finite time before complete melting takes place. This singular behaviour is characterised by the speed of the solid-melt interface and the flux of heat at the interface both becoming unbounded in the blow-up limit. In this paper, we use numerical simulation for a particular energy-conserving one-phase version of the problem to show that kinetic undercooling regularises this blow-up, so that the model with both surface tension and kinetic undercooling has solutions that are regular right up to complete melting. By examining the regime in which the dimensionless kinetic undercooling parameter is small, our results demonstrate how physically realistic solutions to this Stefan problem are consistent with observations of abrupt melting of nanoscaled particles.

Sensing place : embodiment, sensoriality, kinesis, and children behind the camera

This article is a call to literacy teachers and researchers to embrace the possibility of attending more consciously to the senses in digital media production. Literacy practices do not occur only in the mind, but involve the sensoriality, embodiment, co-presence, and movement of bodies. This paper theorises the sensorial and embodied dimension of children���s filmmaking about place in two communities in Australia. The films were created by pre-teen Indigenous and non-Indigenous children in Logan, Queensland, and by Indigenous teenagers at the Warralong campus of the Strelley Community School in remote Western Australia. The films were created through engagement in cross-curricular units that sensitised the students’ experience of local places, gathering corporeal information through their sensing bodies as they interacted with the local ecology. The analysis highlights how the sensorial and bodily nature of literacy practice through documentary filmmaking was central to the children���s formation and representation of knowledge, because knowledge and literacy practices are not only acquired through the mind, but are also reliant on embodiment, sensoriality, co-presence, and kinesics of the body in place.

Moving MobileMums forward: protocol for a larger randomized controlled trial of an improved physical activity program for women with young children

Background: Women with young children (under 5 years) are a key population group for physical activity intervention. Previous evidence highlights the need for individually tailored programs with flexible delivery mechanisms for this group. Our previous pilot study suggested that an intervention primarily delivered via mobile phone text messaging (MobileMums) increased self-reported physical activity in women with young children. An improved version of the MobileMums program is being compared with a minimal contact control group in a large randomised controlled trial (RCT). Methods/design: This RCT will evaluate the efficacy, feasibility and acceptability, cost-effectiveness, mediators and moderators of the MobileMums program. Primary (moderate-vigorous physical activity) and secondary (intervention implementation data, health service use costs, intervention costs, health benefits, theoretical constructs) outcomes are assessed at baseline, 3-months (end of intervention) and 9-months (following 6-month no contact: maintenance period). The trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12611000481976; https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=336109).The intervention commences with a face-to-face session with a behavioural counsellor to initiate rapport and gather information for tailoring the 12-week text message program. During the program participants also have access to a: MobileMums Participant Handbook, MobileMums refrigerator magnet, MobileMums Facebook(C) group, and a MobileMums website with a searchable, on-line exercise directory. A nominated support person also receives text messages for 12-weeks encouraging them to offer their MobileMum social support for physical activity. Discussion: Results of this trial will determine the efficacy and cost-effectiveness of the MobileMums program, and the feasibility of delivering it in a community setting. It will inform the broader literature of physical activity interventions for women with young children and determine whether further investment in the translation of the program is warranted.

Depressive symptoms during pregnancy: Exploring the role of sitting

Statement of problem: Studies exploring relationships between sitting and mental health have been conducted in child and adult, but not pregnant populations. Depression during pregnancy is associated with deleterious outcomes for mothers and children, and shortcomings have been identified in current management strategies. Modifiable lifestyle behaviors may provide more acceptable alternatives to current management strategies if shown to be important. The aim of this study was to explore the relationship between sitting behavior and depressive symptoms in a population of pregnant Australian women. Methods: This pilot cross-sectional study included 81 pregnant women in Brisbane, Australia. Depressive symptoms were measured using the Hospital Anxiety and Depression Scale (HADS). Sitting behavior was measured using the Australian Women's Activity Survey (AWAS). Several potential covariates were also assessed. Linear regression analyses were used to explore the relationship between sitting and depressive symptoms, whilst controlling for known covariates. Results: The model investigating “total sitting time” showed no association with depressive symptoms (F = .77, p = 0.38). The model investigating “planned leisure sitting time” was statistically significant (F = 4.42, p = 0.04): significant contributors to the model variance were HADS anxiety score (p = 0.003) and number of existing children (p = 0.02). “Planned leisure sitting time” showed a statistical trend toward significance (p = 0.06). Conclusions: This study suggests further investigation of the relationship between sitting, particularly planned leisure sitting, and depression during pregnancy is warranted. Future research should include a larger sample and an objective measure of leisure time sitting.
