Advances in life-history knowledge for 35 seahorse species from community science.

Marine community science presents an important route to gather valuable scientific information while also influencing local management and policy, thus contributing to marine conservation efforts. Because seahorses are cryptic but charismatic species, they are good candidates for engaging diverse people to help overcome the many gaps in biological knowledge. We have synthesized information contributed to the community science project iSeahorse from October 2013 to April 2022 for 35 of 46 known seahorse species. We then compared the obtained results with information in existing IUCN Red List assessments, executed from 2014 to 2017, to explore the potential of iSeahorse in expanding seahorse knowledge. Our results show updated geographic ranges for 7 seahorse species, new habitats described for 24 species, observations outside the previously recorded depth range for 14 species, and new information on sex ratio for 15 species and on pregnancy seasonality for 11 species. As one example of the power of iSeahorse, contributed observations on Coleman's pygmy seahorse (Hippocampus colemani) indicated that its geographic range is thousands of square kilometers larger, its habitat more diverse, and its depth range shallower than previously known. It is clear that iSeahorse is expanding knowledge on seahorses to a level that will help improve IUCN Red List assessments. The power of community science for marine conservation in general needs to be fully explored.

The potential for use of haematological and anti-IgE humoral responses as phenotypic markers for tick resistance in cattle.

Approximately 80% of the global cattle population is at risk of infestation and infection by ticks and tick-borne diseases (TTBDs). The economic losses from animal mortality, reduced production, vector control costs and animal treatment are very substantial, hence there is an urgent need to develop and deploy alternative vector control strategies. Breeding for host tick resistance has the potential for sustainable large-scale TTBD control especially in cattle. The gold standard method for phenotyping tick resistance in cattle is by counting ticks on the body but is very laborious and subjective. Better methods for phenotyping tick resistance more objectively, faster and at scale, are essential for selecting host genetic resistance to ticks. This study investigated the correlation between haematological cellular profiles and immunological responses (immunoglobulin E, IgE) and full body tick counts in herds of Bos indicus and Bos taurus following artificial tick challenge with Rhipicephalus decoloratus larvae. Fifty-four Friesian and Ayrshire (Bos taurus) and 52 East African Zebu (Bos indicus) calves were each infested with ∼2500 larvae. Near-replete adult female ticks (≥ 4.5 mm) were counted daily from Day 20-25. Blood and serum samples were obtained from each animal on Days 0 and 23 for cellular blood and IgE titre analysis, respectively. The indicine cattle were refractory to R. decoloratus infestation in comparison with the taurine breed (P < 0.0001). Repeated measurements of blood components pre-infestation revealed a significant (P < 0.05) association with tick count in IgE and red blood cells, haematocrit, and haemoglobin post-infestation. There was also a strong positive correlation between the tick counts and red blood cell numbers, haemoglobin, haematocrit, and IgE concentration (P < 0.0001) following tick challenge. The application of this approach to phenotype host resistance needs to be assessed using higher cattle numbers and with different tick species or genera.

The contribution of objective and perceived crime to neighbourhood socio-inequity in loneliness.

Loneliness tends to be more prevalent in socioeconomically disadvantaged neighbourhoods, yet few studies explore the environmental differences contributing to area-based inequity in loneliness. This study examined how perceived and objective crime contributed to differences in loneliness between advantaged and disadvantaged neighbourhoods. The study used cross-sectional data from 3749 individuals aged between 48 and 77 years, residing in 200 neighbourhoods in Brisbane, Australia. We found that participants in disadvantaged neighbourhoods reported higher levels of loneliness and perceived crime, and the most disadvantaged neighbourhoods also had highest prevalence of objective crime. However, while perceived and objective crime were positively correlated with loneliness, only perceived crime accounted for socio-economic inequity in loneliness. Consequently, perceived crime plays an important role in addressing loneliness in disadvantaged communities and requires equitable resourcing for multiple strategies that aim to decrease crime and increase perceived safety.

Elucidating the Perspectives of Autistic Youth About Their Health Care Experiences: A Qualitative Study.

OBJECTIVES: Autistic individuals have higher rates of co-occurring medical conditions and service use. However, autistic individuals and their families also reported lower satisfaction with health care service delivery. Previous studies described health care experiences of autistic adults, but less is known about those of autistic adolescents and young adults. This study aimed to qualitatively describe the health care experiences of autistic youth. METHODS: Four longitudinal/serial focus groups were conducted with 8 autistic adolescents and young adults. Participants were members of an autistic patient advisory board, which is part of a broader initiative at a large, urban, safety-net hospital to improve the health care experiences of autistic patients. Focus groups were conducted virtually and were audio-recorded. Audio recordings were transcribed and verified for accuracy. Transcripts were consensus-coded with an inductive approach using tenets of grounded theory. RESULTS: Findings included 4 recurring themes: accessibility and accommodations, barriers of health service use, patient involvement in health care decisions, and facilitators of patient-clinician relationship. Participants noted that visit preparation, sensory items, and repeated positive interactions with clinician were helpful to build a positive health care experience. CONCLUSION: Our findings support previous research that suggest the need to individualize care, ensure availability of accommodations, apply flexibility in practice whenever possible, and increase health care professional knowledge about this unique patient population.

Nocardia species distribution and antimicrobial susceptibility within Australia.

BACKGROUND: Nocardia is a ubiquitous saprophyte capable of causing human disease. Disease is primarily respiratory or cutaneous, usually acquired via inhalation or inoculation. Under the influence of environmental and host factors, Nocardia incidence and species distribution demonstrate geographical variation. AIMS: To examine for differences in Nocardia incidence within Western Australia (WA) and analyse species distribution in the context of prior published studies. To analyse antibiogram data from a nationwide passive antimicrobial resistance surveillance program. METHODS: Retrospective extraction of laboratory data for Western Australian Nocardia isolates over a 21-year period. Analysis of Nocardia antimicrobial susceptibility testing data submitted to the Australian Passive Antimicrobial Resistance Surveillance (APAS) program between 2005 and 2022. RESULTS: Nine hundred sixty WA isolates were identified, giving an annual incidence of 3.03 per 100 000 population with apparent latitudinal variation. The four most common species identified within WA and amongst APAS isolates were N. nova, N. cyriacigeorgica, N. brasiliensis and N. farcinica. APAS data demonstrated that all species exhibited high rates of susceptibility to linezolid (100%) and trimethoprim-sulfamethoxazole (98%). Amikacin (>90% susceptibility for all species except N. transvalensis) was the next most active parenteral agent, superior to both carbapenems and third-generation cephalosporins. Susceptibility to oral antimicrobials (other than linezolid) demonstrated significant interspecies variation. CONCLUSIONS: We demonstrate geographical variation in the distribution of Nocardia incidence. Four species predominate in the Australian setting, and nationwide data confirm a high in vitro susceptibility to trimethoprim-sulphamethoxazole and linezolid, justifying their ongoing role as part of first-line empiric therapy.

Associations between changes in crime and changes in walking for transport with effect measure modification by gender: A fixed-effects analysis of the multilevel longitudinal HABITAT study (2007-2016).

Walking for transport is a potential solution to increasing physical activity in mid to older aged adults however neighbourhood crime may be a barrier. Using data from the How Areas in Brisbane Influence HealTh and AcTivity (HABITAT) study 2007-2016, this study examined associations between changes in crime (perceived crime and objectively measured crime) and changes in transport walking, and whether this association differed by gender. Fixed effects regression modelled associations between changes in crime and changes in transport walking, with interaction terms examining effect modification by gender. Positive associations were found between crimes against person and walking for transport. There was no evidence of effect modification by gender. Understanding the relationship between crime and walking for transport can inform policies aimed at promoting transport walking.

Construct and criterion validity of muscle ultrasonography for assessment of skeletal muscle in patients recovering from COVID-19.

Background: The purpose was to investigate the content, construct, and criterion validity of muscle ultrasound in a mixed cohort of participants recovering from mild and critical COVID-19. Methods: A secondary analysis of a prospective cross-sectional study was conducted on data obtained from a battery of muscle and physical function assessments including a muscle biopsy and muscle ultrasonography (US). Rectus femoris (RF) muscle thickness (mT), quadricep complex (QC) mT, RF muscle cross-sectional area (CSA) using 2D freeform trace and estimated from Feret's diameter, and RF echo intensity (EI) were assessed with US. Muscle fiber CSA, fiber type, protein content in muscle fibers, extracellular matrix content (ECM; wheat-germ agglutin), and percent area of collagen in ECM (picrosirius red) were examined from vastus lateralis muscle biopsies. Spearman rho correlations (r) were performed to assess validity of ultrasound parameters. Results: Thirty-three individuals participated including 11 patients surviving critical COVID-19, 15 individuals recovering from mild-COVID, and 7 controls. There were several significant correlations between RF mT, QC mT, RF CSA, and RF EI with age, comorbid burden, body-mass index, and measures of muscle strength, muscle power, and physical function (range r = 0.35-0.83). RF Feret's CSA correlated to CSA of type II muscle fibers (r = 0.41, p = 0.022) and the average size of all muscle fibers (r = 0.39, p = 0.031). RF EI was correlated with collagen in muscle ECM (r = 0.53, p = 0.003) and protein content in muscle tissue (r = -0.52, p = 0.012). Conclusion: Muscle size and quality measured using US has moderate content and construct validity, and to lesser extent, fair to moderate criterion validity in a mixed cohort of individuals recovering from COVID. Muscle ultrasound quality (EI) appears to be sensitive at detecting muscle dysfunction as it is associated with strength, power, physical function, and collagen distribution in a mixed group of individuals recovering from COVID-19.

Trauma and loss in the Adult Attachment Interview: Situating the unresolved state of mind classification in disciplinary and social context.

This article examines how 'trauma' has been conceptualised in the unresolved state of mind classification in the Adult Attachment Interview, introduced by Main and Hesse in 1990. The unresolved state of mind construct has been influential for three decades of research in developmental psychology. However, not much is known about how this measure of unresolved trauma was developed, and how it relates to other conceptualisations of trauma. We draw on previously unavailable manuscripts from Main and Hesse's personal archive, including various editions of unpublished coding manuals, and on Main-Bowlby correspondence from the John Bowlby Archive at the Wellcome Trust in London. This article traces the emergence of the unresolved state of mind classification, and examines the assumptions about trauma embedded in the construct. These assumptions are situated both in the immediate context of the work of Main and Hesse and in terms of wider discourses about trauma in the period. Our analysis considers how a particular form of trauma discourse entered into attachment research, and in doing so partly lost contact with wider disciplinary study of trauma.

The architecture of mental health: identifying the combination of apartment building design requirements for positive mental health outcomes.

Background: Housing quality is a crucial determinant of mental health. While the construction of high-rise buildings is a popular policy strategy for accommodating population growth in cities, there is considerable debate about the health consequences of living in poorly designed apartments. Drawing on three Australian state government apartment design policies introduced to improve apartment design quality, this study aimed to identify the combination of design requirements that were optimally supportive of positive mental health. Methods: K-means cluster analyses identified groups of buildings (n = 172) that were homogenous in their implementation of a mix of n = 80 measured design requirements. Positive mental health was measured using the Warwick-Edinburgh Mental Well-being Scale (WEMWBS). Linear mixed-effects models controlling for demographic characteristics, self-selection factors and clustering of participants within buildings compared residents in the different clusters. Findings: Residents in the "high policy performance buildings", characterised by having a greater implementation of n = 29 design requirements across nine design elements, had significantly higher (+1.96 points) WEMWBS scores compared with residents in the "low policy performance buildings". Interpretation: This study is the first to empirically identify a mix of policy-specific architecture design requirements that are associated with positive mental health in apartment residents. These findings provide vital empirical evidence to inform national and international apartment and high-rise housing policies, and design instruments and practices to protect people's health in apartment dwellings.

What are the lessons from COVID-19 for creating healthy, sustainable, resilient future cities?

The COVID-19 pandemic has disrupted lives and the economy, reminding the global community of the devastating health and economic impacts of uncontrolled infectious disease. It has affected how and where people live, work, shop, and play, and exposed our cities' vulnerabilities, leading to calls for a health lens to be applied in designing, approving, and evaluating city plans. Socioeconomic, spatial and health inequities have been amplified, particularly for those living in inadequate or poorly designed housing, neighbourhoods, and cities. Hence, city mayors have committed to 'build back better' with all daily living amenities within a 15-min walking or cycling trip. Designed well, these cities have the potential to be healthier, more sustainable, equitable, and resilient. Yet their delivery requires a rethink of city planning. Drawing on lessons from the COVID-19 pandemic, we argue that to reduce the risk of future pandemics, we must mitigate climate change, limit urban expansion, and use nature-based solutions to protect natural habitats and biodiversity. We then explore how healthy, sustainable, and resilient 15-minute cities could be planned to reduce emissions and ensure our cities are more resilient in the event of future crises. Given that higher density housing underpins the success of 15-minute cities, we also examine how to create more resilient housing stock, through well-implemented health-supportive apartment design standards. Finally, we argue that to achieve all this, cross-sector leadership and investment will be vital.

'It feels smaller now': The impact of the COVID-19 lockdown on apartment residents and their living environment - A longitudinal study.

Introduction: The COVID-19 pandemic and associated lockdown restrictions prolonged residents' exposure to their home environment. The impact of lockdowns could be heightened for apartment residents as they typically have smaller, less versatile homes, and share communal and circulation spaces. This study examined changes in apartment residents' perceptions and experiences of their dwelling before and after the Australian COVID-19 national lockdown. Methods: Participants consisted of 214 Australian adults who completed a survey on apartment living between 2017 and 2019 and a follow-up survey in 2020. Questions focused on residents' perceptions of their dwelling design, apartment living experiences, and personal life events/changes due to the pandemic. Differences between pre- and post-lockdown periods were assessed via paired sample t-tests. The lived experience of a subset of residents (n = 91) following lockdown was also assessed using qualitative content analysis of free-text responses to an open-ended survey item. Results: Compared to the pre-pandemic period, after the lockdown residents reported less satisfaction with the amount/layout of their apartment space and private open space (e.g., balconies or courtyards). Increased noise annoyance from indoor and outdoor noise sources was also reported, however disputes with neighbours decreased. The qualitative content analysis highlighted a complex interplay of personal, social and environmental impacts of the pandemic on residents. Conclusions: Findings suggest an increased 'dose' of the apartment facilitated by stay-at-home orders negatively influenced residents' apartment perceptions. Design strategies that maximise spacious, flexible dwelling layouts with health-promoting elements (e.g., enhanced natural light/ventilation and private open space) are recommended to promote healthy and restorative living environments for apartment residents.

A state-wide implementation of a whole of hospital sepsis pathway with a mortality based cost-effectiveness analysis from a healthcare sector perspective.

With global estimates of 15 million cases of sepsis annually, together with a 24% in-hospital mortality rate, this condition comes at a high cost to both the patient and to the health services delivering care. This translational research determined the cost-effectiveness of state-wide implementation of a whole of hospital Sepsis Pathway in reducing mortality and/or hospital admission costs from a healthcare sector perspective, and report the cost of implementation over 12-months. A non-randomised stepped wedge cluster implementation study design was used to implement an existing Sepsis Pathway ("Think sepsis. Act fast") across 10 of Victoria's public health services, comprising 23 hospitals, which provide hospital care to 63% of the State's population, or 15% of the Australian population. The pathway utilised a nurse led model with early warning and severity criteria, and actions to be initiated within 60 minutes of sepsis recognition. Pathway elements included oxygen administration; blood cultures (x2); venous blood lactate; fluid resuscitation; intravenous antibiotics, and increased monitoring. At baseline there were 876 participants (392 female (44.7%), mean 68.4 years); and during the intervention, there were 1,476 participants (684 female (46.3%), mean 66.8 years). Mortality significantly reduced from 11.4% (100/876) at baseline to 5.8% (85/1,476) during implementation (p>0.001). Respectively, at baseline and intervention the average length of stay was 9.1 (SD 10.3) and 6.2 (SD 7.9) days, and cost was $AUD22,107 (SD $26,937) and $14,203 (SD $17,611) per patient, with a significant 2.9 day reduction in length of stay (-2.9; 95%CI -3.7 to -2.2, p<0.01) and $7,904 reduction in cost (-$7,904; 95%CI -$9,707 to -$6,100, p<0.01). The Sepsis Pathway was a dominant cost-effective intervention due to reduced cost and reduced mortality. Cost of implementation was $1,845,230. In conclusion, a well-resourced state-wide Sepsis Pathway implementation initiative can save lives and dramatically reduce the health service cost per admission.

Investigating volatile semiochemical production from Bos taurus and Bos indicus as a novel phenotype for breeding host resistance to ixodid ticks.

Ticks and tick-borne diseases cause significant loss in livestock production with about 80% world's cattle at risk. The cost of chemical control is high and there is an ever-increasing tick resistance to chemical acaricides. Genetic selection as alternative long-term control strategy is constrained by laborious phenotyping using tick counts or scores. This study explored the use of host volatile semiochemicals that may be attractants or repellents to ticks as a phenotype for new tick resistance, with potential to be used as a proxy in selection programmes. Approximately 100 young cattle composed of Bos indicus and Bos taurus were artificially infested with 2,500 African blue tick, Rhipicephalus decoloratus larvae, with daily female tick (4.5 mm) counts taken from day 20 post-infestation. Volatile organic compounds were sampled from cattle before and after tick infestation by dynamic headspace collection, analysed by high-resolution gas chromatography (GC) and subjected to multivariate statistical analysis. Using 6-day repeated measure analysis, three pre-infestation GC peaks (BI938 - unknown, BI966 - 6-methyl-5-hepten-2-one and BI995 - hexyl acetate) and one post-infestation GC peak (AI933 - benzaldehyde / (E)-2-heptenal) were associated with tick resistance (P < 0.01 and P < 0.05 respectively). The high correlation coefficients (r = 0.66) between repeated records with all volatile compounds support the potential predictive value for volatile compounds in selective breeding programmes for tick resistance in cattle.

Neighbourhood socio-economic disadvantage and loneliness: the contribution of green space quantity and quality.

Disadvantaged areas experience higher levels of loneliness than advantaged areas, though studies rarely identify environmental determinants of neighbourhood inequity in loneliness. We studied the contribution of the quantity and quality of green space to neighbourhood inequity in loneliness in three buffer sizes (400 m, 800 m, 1600 m), using cross-sectional data from 3778 individuals aged 48-77 years old living in 200 neighbourhoods in Brisbane, Australia. Levels of loneliness were significantly higher in disadvantaged neighbourhoods, and these neighbourhoods had less green space and less access to quality green space. However, there was no evidence that neighbourhood disparities in green space contributed to the association between neighbourhood disadvantage and loneliness. Possible methodological and substantive reasons for this result are discussed.

Effective cell membrane tension is independent of polyacrylamide substrate stiffness.

Most animal cells are surrounded by a cell membrane and an underlying actomyosin cortex. Both structures are linked, and they are under tension. In-plane membrane tension and cortical tension both influence many cellular processes, including cell migration, division, and endocytosis. However, while actomyosin tension is regulated by substrate stiffness, how membrane tension responds to mechanical substrate properties is currently poorly understood. Here, we probed the effective membrane tension of neurons and fibroblasts cultured on glass and polyacrylamide substrates of varying stiffness using optical tweezers. In contrast to actomyosin-based traction forces, both peak forces and steady-state tether forces of cells cultured on hydrogels were independent of substrate stiffness and did not change after blocking myosin II activity using blebbistatin, indicating that tether and traction forces are not directly linked. Peak forces in fibroblasts on hydrogels were about twice as high as those in neurons, indicating stronger membrane-cortex adhesion in fibroblasts. Steady-state tether forces were generally higher in cells cultured on hydrogels than on glass, which we explain by a mechanical model. Our results provide new insights into the complex regulation of effective membrane tension and pave the way for a deeper understanding of the biological processes it instructs.

What is the cost, impact, and willingness to pay for an Amputee Peer Support Program?

BACKGROUND: The provision of peer support from those who have already made positive adjustments to amputation is recommended for people incurring a major limb amputation; however, few receive this service. OBJECTIVE: From a program perspective, determine the cost, impact, and willingness to pay for an Amputee Peer Support Program. STUDY DESIGN: Cost analysis. METHODS: Cost of the Amputee Peer Support Program included a cost analysis of program data over a 5-year time horizon (2013-2018) reported in Australian Dollars 2018/2019. Impact and willingness to pay for an Amputee Peer Support Program was determined through surveys of the 3 participant groups: referring health professionals, program volunteers, and program participants. RESULTS: Over 5 years, there were 793 program participants, serviced by 256 program volunteers, for a cost of $631,497. The cost per program participant was $796. Thirty-eight health professionals, 86 program volunteers, and 12 program participants reported on impact and willingness to pay. The Program was reported to have a positive impact on all participant groups. The themes of access to resources and information and the provision of social and emotional well-being were identified across all 3 groups as being important. All 3 groups reported a higher willingness to pay for the health service (range $113-$450), National Disability Insurance Scheme ($156-$432), and private health insurance ($153-$347), and a lower willingness to pay for the program participant ($23-$49). CONCLUSION: Amputee peer support had a positive impact on those receiving and providing the service. Amputee peer support is likely to be a powerful yet inexpensive addition to routine care.

Improving stroke clinical guideline adherence in an Australian hospital using a clinician-led implementation process.

BACKGROUND: Private hospitals in Australia manage 11% of acute and 48% of rehabilitation stroke admissions, yet little is known about implementation of stroke clinical guidelines in this setting. Clinical guidelines recommend that acute stroke patients be co-located in a stroke unit in a geographically defined area, rather than dispersed across the hospital. OBJECTIVE: To investigate post-intervention adherence to clinical guidelines for stroke management, and to explore staff barriers and facilitators to guideline implementation. METHODS: Observational study before-and-after local implementation of Australian stroke clinical guidelines. The primary outcome was a change in the proportion of patients who were physically co-located in an acute stroke unit. Secondary outcomes included changes in adherence to additional acute and rehabilitation guideline criteria, and staff identification of barriers and facilitators to guide implementation. Data were collected from medical record audits, health service information and staff surveys. RESULTS: Co-location in an acute stroke unit did not change significantly after guideline implementation (49% adherence pre-intervention and 54% post-intervention). Across acute and rehabilitation wards, 15% (11/72) of guideline criteria improved (p < .05). These related to assessments of swallowing and neglect, presence of a stroke care co-ordinator and occupational therapist, post-discharge care plan, provision of patient education and return to driving. Facilitators to guideline implementation included staff education, collaboration, and dissemination of user-friendly stroke policies. CONCLUSION: Stroke clinical guideline implementation led to a favorable uptake of some criteria, yet not all. Implementation was assisted by staff education, user-friendly stroke policies and multidisciplinary team collaboration.

Using normalization process theory to inform practice: evaluation of a virtual autism training for clinicians.

Background: There is growing demand for developmental and behavioral pediatric services including autism evaluation and care management. Clinician trainings have been found to result in an increase of knowledge and attitudes. This study utilizes Normalization Process theory (NPT) to evaluate a clinician training program and its effects on practice. Methods: The year-long virtual training program about autism screening and care management included didactic portions and case presentations. Focus groups and interviews were conducted with primary care clinicians (n = 10) from community health centers (n = 6) across an urban area five months post-training. Transcripts were deductively coded using NPT to uncover barriers to implementation of autism screening and care, benefits of the training program, and areas for future training. Results: Participants were motivated by the benefits of expanding and improving support for autistic patients but noted this effort requires effective collaboration within a complex network of care providers including clinicians, insurance agencies, and therapy providers. Although there were support that participants could provide to families there were still barriers including availability of behavior therapy and insufficient staffing. Overall, participants positively viewed the training and reported implementing new strategies into practice. Conclusion: Despite the small sample size, application of NPT allowed for assessment of both training delivery and implementation of strategies, and identification of recommendations for future training and practice sustainability. Follow-up focus groups explored participants' practice five months post-program. Variations in participants' baseline experience and context at follow-up to enable application of skills should be considered when using NPT to evaluate clinician trainings.

Grand designs for design policy: Associations between apartment policy standards, perceptions of good design and mental wellbeing.

Comprehensive apartment design policies have been legislated by Australian state governments to address concerns about poor design in residential buildings. These policies aim to improve apartment design and promote good health. This study examined whether: (1) residents living in apartments that implemented more minimum design requirements perceived better apartment design and amenity; and (2) increased implementation of minimum requirements and better perceptions of design were associated with positive mental wellbeing. Apartment complexes (n = 114, built 2006-2016) were sampled from Sydney, Perth, and Melbourne. Building plans and elevations were used to measure and score apartments for their implementation of 96 quantifiable policy-specific requirements and residents (n = 1072) completed a self-report survey on their apartment design and health. Multi-level linear regression models were used to account for clustered data. Residents in apartments with greater implementation of requirements for solar and daylight, indoor space, private open space, communal space and parking had more positive perceptions of their apartment in terms of natural light and winter thermal comfort, indoor space and layout, private open space, communal area quality, and parking, respectively (all p < 0.05). Perceptions of natural ventilation, summer thermal comfort, indoor space, and communal area quality were independently associated with positive mental wellbeing (all p < 0.05), but the objective implementation scores had no direct association. When implemented as intended, minimum requirements had a positive impact on perceptions of design, which were associated with mental wellbeing. The study underscores the importance of planning instruments and design review processes that increase industry uptake of minimum policy standards.

Measuring the high life: A method for assessing apartment design policy implementation.

This paper introduces a comprehensive method to measure the implementation of residential apartment design policies in Australia. It describes a protocol for extracting and measuring potentially health-enhancing policy-specific design requirements derived from three current residential apartment design policies in Sydney, Melbourne and Perth. These requirements focus on ten key design elements: (1) solar access, (2) natural ventilation, (3) private open space, (4) communal open space, (5) circulation spaces, (6) acoustic privacy, (7) outlook and (8) visual privacy, (9) bicycle and car parking and (10) apartment mix. This paper also describes the computation of scores to quantify the levels of on-ground implementation of the design requirements and compliance with the policies. The method will allow researchers to objectively quantify, benchmark and assess the uptake of apartment policy in apartment design and construction to inform future policy development. • Measurements were developed to systematically assess apartment buildings for their implementation of specific design requirements stipulated by State Government design policies. • Policy implementation was defined as the degree to which the apartment buildings adhered to the requirements outlined by the apartment design policies. A scoring system was developed to quantify policy implementation at both the apartment and building levels. • This method can be replicated to allow researchers to objectively quantify, benchmark and assess the uptake of apartment policy in apartment design and construction to inform future policy development.
