Socioeconomic Status and Health: Why is the Relationship Stronger for Older Children?

Case, Lubotsky, and Paxson (2001) show that the well-known relationship between socio- economic status (SES) and health exists in childhood and grows more pronounced with age. However, in cross-sectional data it is difficult to distinguish between two possible explanations. The first is that low-SES children are less able to respond to a given health shock. The second is that low SES children experience more shocks. We show, using panel data on Canadian children that: 1) the gradient we estimate in the cross section is very similar to that estimated previously using U.S. children; 2) both high and low-SES children recover from past health shocks to about the same degree; and 3) that the relationship between SES and health grows stronger over time mainly because low-SES children receive more negative health shocks. In addition, we examine the effect of health shocks on math and reading scores. We find that health shocks affect test scores and future health in very similar ways. Our results suggest that public policy aimed at reducing SES-related health differentials in children should focus on reducing the incidence of health shocks as well as on reducing disparities in access to palliative care.

Child Mental Health and Human Capital Accumulation: The Case of ADHD

One in five U.S. youngsters has a mental disorder, but we know little about the effects of these disorders on outcomes. We examine U.S. and Canadian children with symptoms of Attention Deficit Hyperactivity Disorder (ADHD), the most common child mental health problem. Our innovations include the use of large nationally representative samples of children, the use of questions administered to all children rather than focusing only on diagnosed cases, and the use of sibling fixed effects to control for omitted variables. We find large negative effects on test scores and schooling attainment suggesting that mental health conditions are a more important determinant of average outcomes than physical health conditions.

Self-centering bridge pier columns with structural fuses

An innovative structural system for pier columns was investigated through a series of laboratory experiments. The columns and connections examined were comprised of precast concrete segments to accelerate construction. In addition some of the columns employed elastic elements to self-center the columns when subjected to lateral loads and structural fuses to control large lateral deflections, dissipate energy, and expedite repair in the event of a catastrophic loading event. Six cantilever columns with varying component materials and connection details were subjected to a regimen of vertical dead loads and cyclic, quasi-static lateral loads. One column was designed as a control column to represent the behavior of a conventional reinforced concrete column and provide a basis for comparison with the remaining five jointed columns designed with the proposed structural system. After sustaining significant damage, the self-centering, jointed columns were repaired by replacing the structural fuses and retested to failure to investigate the effectiveness of the repair. The experiments identified both effective and unsatisfactory details for the jointed system. Two of the jointed columns demonstrated equivalent lateral strength, greater lateral stiffness, and greater lateral deformation capacity than the control column. The self-centering capability of the jointed columns was clearly demonstrated as well, and the repair technique proved effective as demonstrated by nearly identical pre and post repair behavior. The authors believe the proposed system to be a feasible alternative to conventional pier systems and recommend additional research

A collaborative autoethnography on challenging sociohistorical constructions of gender in teacher education

In early 2019, we developed a workshop that examines changing representations of masculinities and femininities through advertisements from today and from 30 years ago. We employ a pedagogy of discomfort (Boler, 1999) and challenge participants—whether students, teacher candidates, or seasoned educators—to historicize and critique how they co-construct sociohistorical representations and performativity of gender (Butler, 1990). Our hopes are that participants begin deconstructing how and which understandings of gender became normalized to them, as well as how they perpetuate or disrupt “masculinities” and “femininities”. Through regular debriefing, we realized that we do not merely facilitate but also actively participate in each workshop, not just guiding but also being guided by changing discussions with every iteration, suggesting needs to historicize and critique our own discomforts in relation to participants’ engagements. In identifying and reflecting on ‘critical moments’ from our workshops, we conducted a collaborative autoethnography (CAE) to examine not only how participants responded to our call for unpacking their representations, but also how participants caused us to challenge our own representations. In using CAE, our experiences and reflections became our data, and we analyzed interpretations of experiences for commonalities and differences, creating opportunities to deconstruct our relationalities in constructing and historicizing representations (Hernandez, Chang & Ngunjiri, 2017). In this article, we discuss how this process affected the workshop’s evolution and our continued self-analysis. We argue that if students are to interrogate sociohistorical gender constructions, educators must continuously examine how their own discomforts influence their engagement with students’ responses

Pet owner and vet interactions: exploring the drivers of AMR

Background: Antimicrobial resistance (AMR) is a growing public health problem across the world. As the negative consequences of AMR become apparent at local, national and international levels, more attention is being focussed on the variety of mechanisms by which AMR is potentiated. We explore how interactions between pet owners and veterinarians represent a key arena in which AMR-related behaviours can be shaped. Methods: In depth semi-structured interviews were carried out with pet owners (n = 23) and vets (n = 16) across the UK in 2017. A thematic analysis approach was taken, with inductively gathered data analysed deductively using a behavioural framework to identified key behaviours emerging from participant accounts which were amenable to change. Results: Interactions between vets and pet owners were characterised by misunderstandings and misconceptions around antibiotics by pet owners, and a lack of clarity about the positions and intentions of the other party. Vets and pet owners had differing perceptions of where pressure to prescribe antibiotics inappropriately originated. Vets perceived it was mostly pet owners who pushed for inappropriate antibiotics, whereas pet owners reported they felt it was vets that overprescribed. Low levels of understanding of AMR in general were apparent amongst pet owners and understandings with regard to AMR in pets specifically were almost non-existent in the sample. Conclusions: Improved use of antibiotics could be assisted by educating the pet owning public and by guideline development for companion animal vets, concurrent development of mandatory legislation, increased consultation time to facilitate better communication, development of vet training on antimicrobial therapy and stewardship led interactions with pet owners, and increased levels of knowledge of pet-related AMR amongst pet owners

Infectious diseases in Northern Australia

[Extract] This issue of Microbiology Australia covers biomedical research and workforce training in Northern Australia and our northern neighbouring countries. The north of Australia is a tropical region and has a larger representation of Australian First Nations peoples than other States and Territories of Australia. In Australia, Aboriginal and Torres Strait Islander people represent 3.2% of the total Australian population. However, in the Northern Territory, the Australian census (2021) shows that approximately 26.3% of the total population identify as Aboriginal and Torres Strait Islander. This underpins the need for Northern Australia to have continued funding to enable health research, workforce training and health and community services that address the currently unmet and still growing needs of this population demographic

Design and Development of an Internationally Applicable Educational Video to Increase Community Awareness in Regions with High Prevalence of Melioidosis and Diabetes

Melioidosis is a neglected tropical disease that causes high morbidity and mortality. Public health awareness is essential for both prevention and early detection of the infection. This project aimed to develop an internationally applicable educational tool to increase community awareness in regions with high prevalence of diabetes and melioidosis. The animation was created with international collaboration. Sixty-four delegates from different cultural backgrounds participated in the survey to evaluate the animation. Feedback was positive, with 85% agreeing that they would use this video for public education and 82% agreeing that the video was culturally appropriate to them in the context of their region. The animation was refined after feedback. To supplement the 3-minute animation, a 13-minute film footage of interviews with clinicians, researchers and patients was also created. These materials have been made available online through the International Melioidosis Network and can be readily downloaded or subtitled in any language using publicly available software, demonstrating the utility of developing low-cost adaptable health education material targeted for widespread use internationally
