Establishing a glossary of community-led housing
No full textRecent decades have seen the re-discovery or emergence of a diverse range of housing models such as cohousing, co-operatives, community land trusts, and other forms that seek to address various persistent issues of social, environmental, and economic justice. This has generated commensurate growth in research on the objectives and outcomes of such models, including the creation of relevant typologies of conceptual approaches and schemas of organisational objectives to build understanding of the field’s theoretical and practical implications. Despite the growth of relevant models, their relative unfamiliarity and diversity of forms and objectives means practitioners, researchers, policymakers, and others associated with the field may not understand the forms and objectives of models under examination and development, leading to delays, project failures, and confusion. This paper therefore presents a glossary of community-led housing as a base on which to continue to foster understanding and growth of relevant models, and enable collaborative and comparative work
The intersocietal IWGDF, ESVS, SVS guidelines on peripheral artery disease in people with diabetes and a foot ulcer
No full textDiabetes related foot complications have become a major cause of morbidity and are implicated in most major and minor amputations globally. Approximately 50% of people with diabetes and a foot ulcer have peripheral artery disease (PAD) and the presence of PAD significantly increases the risk of adverse limb and cardiovascular events. The International Working Group on the Diabetic Foot (IWGDF) has published evidence based guidelines on the management and prevention of diabetes related foot complications since 1999. This guideline is an update of the 2019 IWGDF guideline on the diagnosis, prognosis and management of peripheral artery disease in people with diabetes mellitus and a foot ulcer. For this guideline the IWGDF, the European Society for Vascular Surgery and the Society for Vascular Surgery decided to collaborate to develop a consistent suite of recommendations relevant to clinicians in all countries. This guideline is based on three new systematic reviews. Using the Grading of Recommendations, Assessment, Development, and Evaluation framework clinically relevant questions were formulated, and the literature was systematically reviewed. After assessing the certainty of the evidence, recommendations were formulated which were weighed against the balance of benefits and harms, patient values, feasibility, acceptability, equity, resources required, and when available, costs. Through this process five recommendations were developed for diagnosing PAD in a person with diabetes, with and without a foot ulcer or gangrene. Five recommendations were developed for prognosis relating to estimating likelihood of healing and amputation outcomes in a person with diabetes and a foot ulcer or gangrene. Fifteen recommendations were developed related to PAD treatment encompassing prioritisation of people for revascularisation, the choice of a procedure and post-surgical care. In addition, the Writing Committee has highlighted key research questions where current evidence is lacking. The Writing Committee believes that following these recommendations will help healthcare professionals to provide better care and will reduce the burden of diabetes related foot complications
Explaining the impact of the COVID-19 pandemic on massage therapists in Australia and Canada : a mixed methods study
No full textBackground: The COVID-19 pandemic was a time of rapid change and uncertainty, with individual jurisdictions within countries implementing a variety of preventative measures. At the onset of the pandemic, as little was known about how COVID-19 was transmitted, restrictions, such as lockdowns, were implemented to prevent further spread of this virus. In many jurisdictions, massage therapists were deemed as nonessential for a period. This disruption to their livelihood, as a professional group and without autonomy to decide, was unprecedented. This prompted the question as to whether this experience had impacted massage therapists' professional identity. Methods: A sequential explanatory mixed methods design was used and massage therapists in Australia and Canada were recruited to participate. Results from a quantitative questionnaire completed by 649 respondents and from 31 semistructured interviews from a subset of the questionnaire participants were used in the mixed analysis. Results: Massage therapists, impacted by the pandemic, experienced a discord between what it means to be a massage therapist, providing patient-centered care and the public health initiatives implemented during the pandemic. This discord occurred in multiple situations and the type of discord was influenced by a number of factors, including how therapists identified themselves within the workforce (i.e., as a health care provider or a service provider). Conclusion: This study sought to understand how the COVID-19 pandemic impacted massage therapists' professional identity. Massage therapists reported that the pandemic impacted their professional identity through a lack of congruence and discord between their identity-constituting beliefs and what it means to be a massage therapist. The sequela to this discord was therapists experiencing different types of moral distress and or moral injury. Future research is needed to determine the longer-term impacts of COVID-19 on massage therapists
Insignoic acids A – E, unusual α, β-unsaturated keto fatty acids isolated from the exocarp of Australian rainforest tree Endiandra insignis (Lauraceae)
No full textAnti-inflammatory bioassay-guided compound isolation from the exocarp of the Australian rainforest tree Endiandra insignis (family Lauraceae) has led to the discovery and structural elucidation of unusual α, β-unsat- urated twenty-four carbon fatty acids and their positional isomers, insignoic acids A – E (1a – 5c). The stereo- chemistry and position of the double bond within the aliphatic chain were independently determined via NMR spectroscopy and Ozone-Induced Dissociation (OzID) Mass Spectrometry, respectively. Compounds (1a – 5c) displayed good to moderate anti-inflammatory activity in the range of 8–84 μM. The low therapeutic index observed when assessing the cell viability in the RAW macrophage cell lines, prompted us to investigate the anticancer potential of these unusual fatty acids. The anti-cancer activity was assessed in A-431 carinoma cell lines and MM649 melanoma cell lines. Insignoic acid C (3a-f) exhibited the highest level of potency with an IC50 value of 5–7 μM against both the cell lines. The insignoic acids are the first of their kind known for incorporating an alpha-beta unsaturated system flanked next to a keto group with an additional level of oxygenation at C-6 in a 24‑carbon fatty acid backbone
Green manure substitution for potassium fertilizer promotes agro-ecosystem multifunctionality via triggering interactions among soil, plant and rhizosphere microbiome
No full textAims: Green manuring exhibits strong positive effects on soil fertility and crop yield, while its effects on agro-ecosystem multifunctionality (agro-EMF) and the underlying mechanisms are poorly understood. Methods: Based on a 7-year potato cropping field experiment, we conducted a holistic survey of soil and rhizosphere microbiomes, plant performance (i.e. yield and disease resistance) and soil functions, and assessed agro-EMF under conventional chemical potassium (K) fertilization and green manure (GM) amendment practices. Results: We demonstrated that GM application significantly promoted agro-EMF compared to chemical K fertilizer, as indicated by improved crop yield (5.8%-20.6%), reduction in potato late blight incidence (2.8%-46.2%), and increased soil nutrient contents. GM amendment drastically altered microbial community composition, especially in the rhizosphere. Intriguingly, agro-EMF was primarily predicted by microbial community composition, rather than microbial diversity, with a higher agro-EMF variation explained by the rhizosphere microbiome. In comparison to chemical K fertilizer, GM treatments greatly improved the complexity (58.5%-125.8%) and stability (8.2%-21.5%) of the microbial inter-kingdom network. Correspondingly, GM amendment significantly enriched keystone taxa, including the bacterial taxa Xanthomonadaceae, Rhizobiaceae and Sphingobacteriaceae, the fungal taxon Chaetomiaceae and the protistan taxon Cercozoa in the rhizosphere, of which are closely associated with soil nutrient cycling, plant growth promotion, and disease resistance. Conclusion: Taken together, our study revealed that green manuring greatly promoted agro-EMF via coordinating soil nutrient cycling, rhizosphere microbiome and microbial network interactions for greater crop yield, disease resistance and soil functions. This study provides critical information on the mechanisms of ecosystem functions maintenance in agro-ecosystems and presents a basis towards developing conservation farming practices for agricultural sustainability

The development of tone discrimination in infancy : evidence from a cross-linguistic, multi-lab report
No full textWe report the findings of a multi-language and multi-lab investigation of young infants’ ability to discriminate lexical tones as a function of their native language, age and language experience, as well as of tone properties. Given the high prevalence of lexical tones across human languages, understanding lexical tone acquisition is fundamental for comprehensive theories of language learning. While there are some similarities between the developmental course of lexical tone perception and that of vowels and consonants, findings for lexical tones tend to vary greatly across different laboratories. To reconcile these differences and to assess the developmental trajectory of native and non-native perception of tone contrasts, this study employed a single experimental paradigm with the same two pairs of Cantonese tone contrasts (perceptually similar vs. distinct) across 13 laboratories in Asia-Pacific, Europe and North-America testing 5-, 10- and 17-month-old monolingual (tone, pitch-accent, non-tone) and bilingual (tone/non-tone, non-tone/non-tone) infants. Across the age range and language backgrounds, infants who were not exposed to Cantonese showed robust discrimination of the two non-native lexical tone contrasts. Contrary to this overall finding, the statistical model assessing native discrimination by Cantonese-learning infants failed to yield significant effects. These findings indicate that lexical tone sensitivity is maintained from 5 to 17 months in infants acquiring tone and non-tone languages, challenging the generalisability of the existing theoretical accounts of perceptual narrowing in the first months of life. RESEARCH HIGHLIGHTS: This is a multi-language and multi-lab investigation of young infants’ ability to discriminate lexical tones. This study included data from 13 laboratories testing 5-, 10-, and 17-month-old monolingual (tone, pitch-accent, non-tone) and bilingual (tone/non-tone, non-tone/non-tone) infants. Overall, infants discriminated a perceptually similar and a distinct non-native tone contrast, although there was no evidence of a native tone-language advantage in discrimination. These results demonstrate maintenance of tone discrimination throughout development
[In Press] Masculinities and the lived understandings of bystander responses to everyday violence
No full textAmong criminologists there has been an expanded contemporary interest in measures that encourage bystander intervention in the social settings of escalating and potentially violent incidents. These broadly include partner abuse and domestic disputes, as well as confrontational social interaction and other forms of targeted harassment and violence (racist, sexist, homophobic, ableist etc.), in everyday life. This article considers the likely success or failure of seeking to foster such measures as a core strategy of violence prevention, with discussion of the author’s Sydney- based study of the understandings of violence arising from young men’s lived experience of its various forms. It particularly concentrates on the results of focus groups conducted with a mixed sample of young men (aged 16-25 years) between 2018-2020. These participants had personal engagements with violence and potential violence, that shaped their reservations and doubts about regular intervention and general male anti-violence advocacy as reasonable and achievable social practices
Gastric alimetry expands patient phenotyping in gastroduodenal disorders compared with gastric emptying scintigraphy
No full textIntroduction: Gastric emptying testing (GET) assesses gastric motility, however is non-specific and insensitive for neuromuscular disorders. Gastric Alimetry(GA) is a new medical device combining non-invasive gastric electrophysiological mapping and validated symptom profiling. This study assessed patient-specific phenotyping using GA compared to GET. Methods: Patients with chronic gastroduodenal symptoms underwent simultaneous GET and GA, comprising a 30-minute baseline, 99m TC-labelled egg meal, and 4-hour postprandial recording. Results were referenced to normative ranges. Symptoms were profiled in the validated GA App and phenotyped using rule-based criteria based on their relationships to the meal and gastric activity: i) sensorimotor; ii) continuous; and iii) other. Results: 75 patients were assessed; 77% female. Motility abnormality detection rates were: GET 22.7% (14 delayed, 3 rapid); GA spectral analysis 33.3% (14 low rhythm stability / low amplitude; 5 high amplitude; 6 abnormal frequency); combined yield 42.7%. In patients with normal spectral analysis, GA symptom phenotypes included: sensorimotor 17% (where symptoms strongly paired with gastric amplitude; median r=0.61); continuous 30%; other 53%. GA phenotypes showed superior correlations with GCSI, PAGI-SYM, and anxiety scales, whereas Rome IV Criteria did not correlate with psychometric scores (p>0.05). Delayed emptying was not predictive of specific GA phenotypes. Discussion: GA improves patient phenotyping in chronic gastroduodenal disorders in the presence and absence of motility abnormalities with increased correlation with symptoms and psychometrics compared to gastric emptying status and Rome IV criteria. These findings have implications for the diagnostic profiling and personalized management of gastroduodenal disorders
Gender, diversity, culture, and the Pacific food system : exploring sustainability
No full textIn 2021 the Pacific Community came together to outline a strategy for advancing Blue Pacific Food Systems that is built on an understanding of linkages between the Pacific and the rest of the world, as well as within the Pacific region between its 22 Pacific Islands Countries and Territories (PICTs). The Summary Brief notes Pacific societies have a “…long history and culture of sustainably managing the ocean and land, which has supported Pacific communities for generations.” This traditional sustainability is now under threat. The PICTs face growing development challenges - climate change, urbanisation, non-communicable diseases (NCDs), risk of pathogens and pests, and overfishing - that affect how they obtain sufficient nutritious food to feed their populations.1 This article explores the diversity of the Pacific region, the current Pacific food gap and the important roles of culture and gender in shaping a sustainable Pacific food system
