Trust as viability: How an online outcomes-focussed cultural activity planner helped to deepen trust between a city-based funder and a regional arts producer
No full textCulture's role in sustaining urban development is recognised in this Special Issue and yet the urban setting is not an island of cultural development, but rather merges into suburban, rural and remote areas where the significance of cultural activity and the local actors can be overlooked by the urban observer and funder. In Australia, communities outside of capital cities differ significantly from each other, with community arts and cultural development efforts operating at various scales, to address unique local issues, through diverse artforms and ways of working. Funders with different processes, priorities, and relationships with funding recipients support this activity and can play a role in limiting or enabling community-determined responses to complex local issues. This article explores a case study where adoption of an online outcomes focussed cultural activity planning and evaluation platform unexpectedly contributed to a deepening of trust between a city-based corporate funder and a regional arts producer working in a suburban area of the Illawarra region of New South Wales, Australia. Interviews with stakeholders revealed that the platform, together with the trust that it helped to cultivate, supported a creative, responsive, and flexible community arts and cultural development project that achieved cultural and social outcomes for local young people considered disadvantaged while working towards the funder's global goal to enable social equity. The case study suggests that when funders are removed from the contexts where activities will be delivered, a trusting relationship spanning geographic and socio-cultural divides can encourage mutually beneficial collaboration, reduce rigidity to allow an emergent strategy, and achieve impactful community-determined arts and cultural activity

The findings from this study can be strategically used to analyze emerging trends in digital health, as well as to shape health IT thought leadership in the post-pandemic landscape
Identifying the determinants and consequences of post-recovery satisfaction in B2B customers: a multidimensional justice theory perspective
No full textPurpose: Drawing on justice theory, this study aims to investigate the determinants and consequences of post-recovery satisfaction in a business-to-business (B2B) sales environment. In addition, customer demandingness is used as a moderator in this study to assess the relationship between distributive justice (DJ), procedural justice (PJ) and interactional justice (IJ) and post-recovery satisfaction. Design/methodology/approach: A conceptual framework was developed by testing five hypotheses based on data collected from 337 salesperson–customer dyads. Findings: The findings of this study reveal that DJ, PJ and IJ are positively linked with post-recovery satisfaction. In addition, post-recovery satisfaction negatively impacts customer distrust. On the contrary, customer distrust positively influences value co-creation behavior and has a negative impact on trusting intention. Finally, the customer’s level of demandingness significantly and positively moderates the linkage between the dimensions of justice perception and post-recovery satisfaction. Originality/value: Despite extensive literature on distrust, a research model that examines customers’ distrust attitudes toward service failure and B2B recovery satisfaction needs to be developed and validated. In this regard, the authors developed a framework to measure post-recovery satisfaction and its association with customers’ distrust in B2B a context
Cytoprotective Metal–Phenolic Network Sporulation to Modulate Microalgal Mobility and Division
No full textSynthetic cell exoskeletons created from abiotic materials have attracted interest in materials science and biotechnology, as they can regulate cell behavior and create new functionalities. Here, a facile strategy is reported to mimic microalgal sporulation with on-demand germination and locomotion via responsive metal–phenolic networks (MPNs). Specifically, MPNs with tunable thickness and composition are deposited on the surface of microalgae cells via one-step coordination, without any loss of cell viability or intrinsic cell photosynthetic properties. The MPN coating keeps the cells in a dormant state, but can be disassembled on-demand in response to environmental pH or chemical stimulus, thereby reviving the microalgae within 1 min. Moreover, the artificial sporulation of microalgae resulted in resistance to environmental stresses (e.g., metal ions and antibiotics) akin to the function of natural sporulation. This strategy can regulate the life cycle of complex cells, providing a synthetic strategy for designing hybrid microorganisms
Response of partitioning to cooling rate for different solutes in aluminum alloys
No full textIt is commonly recognized that the cooling rate has a substantial effect on solute partitioning and its resultant microsegregation during solidification. The classical dendrite tip undercooling theory clarifies the mitigation of microsegregation by increasing the cooling rate. However, most of the studies focused on binary alloys, leaving an open question as to whether the microsegregation of different solutes in a multi-component alloy system exhibits a relieving degree similar to increasing cooling rate. Taking a widely used 6022-type Al alloy (Al-0.76Mg-0.93Si-0.2Fe) as a model alloy, the current study reveals that the microsegregation of Mg gets alleviated to the greatest extent, followed by those of Si and Fe when the cooling rate increases from 5 to 128 K/s. This phenomenon is attributed to the solute-based difference in response to partitioning to cooling rate (denoted as Rk). We propose a theoretical equation to quantify Rk, and the Rk values of solute Mg, Si, and Fe successfully explain the rank of solute partitioning in experiments. Furthermore, a broad range of Rk values of other commonly used alloying elements in Al alloys were calculated and ranked, delivering a handy tool to predict the microsegregation behavior and solubility of different solute elements upon sub-rapid solidification, which is consistent with experimental observation. This framework can also be extended to other multi-component alloy systems
Performance of digital image correction technique for mild steel with different strain hardening effects
No full textThis paper investigates the performance of Digital Image Correction (DIC) technique in determining the initial fracture toughness of mild steel with different strain hardening effects. To achieve this goal, the results of DIC technique-based method are compared with those of the commonly used unloading compliance (UC) method. The comparison results reveal that the DIC technique-based method exhibit a good agreement with the UC method in determining initial fracture toughness, with a deviation of less than 3.0 %. Additionally, the DIC technique-based method demonstrates the consistency in determining the initial fracture toughness, independent of the ratio of initial pre-crack length to width. Furthermore, the importance of strain hardening effects on initial fracture toughness follows the order of strain hardening capacity, effective yield stress, and yield offset. The significance of this paper is that it provides a deep understanding of the performance of the DIC technique in determining the initial fracture toughness of mild steel
Osteopathy Referrals to and from General Practitioners: Secondary Analysis of Practitioner Characteristics from an Australian Practice-Based Research Network
No full textAustralian osteopaths engage in multidisciplinary care and referrals with other health professionals, including general practitioners (GPs), for musculoskeletal care. This secondary analysis compared characteristics of Australian osteopaths who refer to, and receive referrals from, GPs with osteopaths who do not refer. The analysis was undertaken to identify pertinent characteristics that could contribute to greater engagement between Australian osteopaths and GPs. Data were from the Australian osteopathy practice-based research network comprising responses from 992 osteopaths (48.1% response rate). Osteopaths completed a practice-based survey exploring their demographic, practice, and clinical management characteristics. Backward logistic regression identified significant characteristics associated with referrals. Osteopaths who reported sending referrals (n = 878, 88.5%) to GPs were more likely than their non-referring colleagues to receive referrals from GPs (aOR = 4.80, 95% CI [2.62–8.82]), send referrals to a podiatrist (aOR = 3.09, 95% CI [1.80–5.28]) and/or treat patients experiencing degenerative spinal complaints (aOR = 1.71, 95% CI [1.01–2.91]). Osteopaths reporting receiving referrals (n = 886, 89.3%) from GPs were more likely than their non-referring colleagues to send referrals to GPs (aOR = 4.62, 95% CI [2.48–8.63]) and use the Medicare EasyClaim system (aOR = 4.66, 95% CI [2.34–9.27]). Most Australian osteopaths who report engaging in referrals with GPs for patient care also refer to other health professionals. Referrals from GPs are likely through the Chronic Disease Management scheme. The clinical conditions resulting in referrals are unknown. Further research could explore the GP–osteopath referral network to strengthen collaborative musculoskeletal care. The outcomes of this study have the potential to inform Australian osteopaths participating in advocacy, public policy and engagement with Australian GPs
Development of Work Breakdown Structure (WBS) in High-Rise Office Buildings using Green Retrofitting based on GBCI and Minister of PUPR Regulation No. 21 of 2021 to Improve the Quality of Resource Planning
No full textBuildings built before the 2000s are still vulnerable to exposure to the importance of energy efficiency, so renovations are needed on this existing building through renovation (green retrofitting) for sustainability goals that reduce energy expenditure. Modification is an effort to adjust the performance of built buildings to obtain a certificate as a green building. Both government and non-government agencies certify customization with different benchmarks/ parameters. In Indonesia, there are two regulations and benchmarks in the assessment of BGH performance, namely the Green Building Council Indonesia (GBCI) and PUPR Regulation Number 21 of 2021. The portion of existing high-rise office buildings is 98% of the total number of office buildings, which is very significant in achieving the government's target. The obstacle to implementing Green Retrofitting in High-Rise Office Buildings is the high cost. To be able to make green retrofitting costs efficient, researchers conducted a statistical analysis using the Relative Important Index (RII). The results of this study showed that the most influential factors at the planning stage were the energy-saving SOP document with an index of 0,996, the construction stage was Document on the implementation of ideas and innovations in construction methods with an index of 0,992, and the post-construction stage was Certificate of Expert Building Management Manager with an index of 0,998. The implementation of customization can be through the development of a Work Breakdown Structure (WBS), to detail the resources needed in project planning, monitoring, and control. The results of the study are proof that the WBS structure of customization work based on GBCI and PUPR Regulation Number 21 of 2021 affects improving the quality of resource planning using survey methods and literature studies
Assessing the Influence of Banana Leaf Ash as Pozzolanic Material for the Production of Green Concrete: A Mechanical and Microstructural Evaluation
No full textThis paper reports an investigation of the mechanical and microscopic properties of partially replaced banana leaf ash (BLA) concrete. In this research, the cement was partially replaced by BLA in two phases: Phase A (0%, 5%, 10%, 15%, 20%, 25% and 30%) and Phase B (0%, 10%, 20% and 30%). The consequence of partially replacing cement with BLA in concrete was investigated by the application of a range of tests, namely X-ray fluorescence (XRF), compressive strength, splitting tensile strength, flexure strength, ultrasonic pulse velocity and scanning electron microscopy (SEM) analysis. The properties were then correlated with the properties of a standard 100% Portland cement concrete of similar strength. The XRF result of the BLA identified a composition with 48.93% SiO2 and 3.48% Al2O3, which indicates that the material potentially possesses pozzolanic properties. The mechanical properties of the partially replaced BLA concrete noted minor strength loss, approximately 5% with 20% partial replacement. The nondestructive testing data showed enhanced performance up to 20% partial replacement, with ultrasonic pulse values above 3500 m/s. The scanning electron microscopy analysis illustrated that the morphology of BLA specimens contained increased microcracks compared with the control. The decrease in strength observed is attributed to the fibrous composition of the BLA. The mechanical, nondestructive testing and microscopic results highlight the potential to utilize BLA as a partial replacement for cement as a pozzolanic material in concrete at up to 20% by weight of cement
Stability of unsaturated soil slope considering stratigraphic uncertainty and rotated anisotropy of soil properties
No full textThe stratigraphic uncertainty and rotated anisotropy of soil properties exist widely in nature. Recent studies have shown that the slope stability was significantly influenced by these two uncertainties. However, there is no proper method for simulating these two uncertainties at the same time, and the influence of the two uncertainties has not been considered in previous unsaturated soil slope stability analysis. This paper aims to propose a coupled method for characterizing the stratigraphic uncertainty and rotated anisotropy of soil properties, and investigate the unsaturated soil slope stability considering the two uncertainties. Through a slope case, the proposed method for characterizing the two uncertainties is examined. The effect of rotational angle on the slope stability and groundwater table is studied. In addition, four different uncertainty considerations are chosen to compare their influence on the slope stability and groundwater table. The results show that the proposed method can well characterize the two uncertainties at the same time. The rotational anisotropy of soil properties has a substantial impact on the slope stability and groundwater table. The rotational angles corresponding to the maximum and minimum reliability index of slope depend on the uncertainty considerations in the slope stability analysis. The slope reliability index only considering stratigraphic uncertainty is the highest, and the slope reliability index considering stratigraphic uncertainty and rotated anisotropy of soil properties is the lowest
