Indigenous Australian Entrepreneurs: Not all community organisations, Not all in the outback

The media, academic publications and parliamentary speeches typically perceive Indigenous business enterprises as 'community' run ventures. This blanket characterisation is inadequate as it renders the individual Indigenous urban entrepreneur invisible and unconsidered. Confusion in public reporting and accountability has resulted in misconceptions that cloud the image of what a successful Indigenous entrepreneur is. In addition, previous published literature seems skewed towards the rural or remote areas when in fact, almost three-quarters of Indigenous Australians live in urban areas. Little is known of the individual, urban and provincial Indigenous Australian entrepreneur

Expanding Australian Indigenous Entrepreneurship Education Ecosystems

Australian Indigenous entrepreneurship and entrepreneurship education represents a significant opportunity for Indigenous people to enhance their entrepreneurial skills, in turn building vibrant Indigenous-led economies that support sustainable economic development and social well-being. This study is the first of its kind to explore the conceptualization of a framework of Australian Indigenous entrepreneurship education ecosystems. The purpose is to provide emergent inquiry and participatory action research into entrepreneurship education ecosystems, enabling the expansion of Indigenous research and practice; with the objective of delineating specific fundamentals associated with Indigenous entrepreneurs, such as limitations in social, human, and financial capital. We include and integrate Australian Indigenous value perspectives, including Indigenous knowledge, wisdom, and resilience, as well as the cultural captivity of entrepreneurship and Indigenous culture. The addition to the body of knowledge provides practical implications and a framework to the benefit of all ecosystem participants, including entrepreneurship educators, Indigenous entrepreneurs, policy-makers, training suppliers, and dynamic institutional participants, such as incubators, accelerators, and community development initiatives

Angiographic Findings in Diaphragmatic Rupture

The angiographic findings are presented in four patients with ruptured diaphragms. With rupture of the left hemidiaphragm the findings vary with the structures herniating. Gastric, mesenteric or splenic artery branches extending into the lower chest indicate herniation of the stomach, bowel or spleen. A herniating spleen is frequently ruptured. On the right, the liver is generally the only organ to herniate. An indentation in the lateral liver margin in the venous phase, if present, indicates the level of the diaphragm.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73631/1/j.1440-1673.1976.tb02012.x.pd

Ongoing growth in the number of Indigenous Australians in business

In 2014, Boyd Hunter attempted to provide a consistent estimate of the growth in Indigenous self-employment between 1991 and 2011. Changes in the census questionnaire structure and sequencing means that projecting the growth trends back to 1991 is now problematic. This paper provides a more refined, consistent and transparent method for calculating the number of Indigenous owner–managers operating in the economy, including accounting for the growing prevalence of Indigenous owner–managers who are increasingly identifying themselves as Indigenous in the census, unlike in previous censuses where many did not identify. Using census data and estimated residential population statistics, we conservatively estimate that around 17 900 Indigenous business owner–managers operated in Australia in 2016. We estimate that the number of Indigenous business owner–managers grew by 30% between 2011 and 2016. The rate of Indigenous business ownership has grown marginally as a share of the Indigenous working-age population at a time when the non-Indigenous rate of business ownership has fallen. Yet the rate of Indigenous business ownership remains relatively low compared with the rate of business ownership among non-Indigenous Australians. The paper also provides insights about the characteristics of Indigenous owner–managers, including their number, geographic distribution, gender composition, industrial sectors, and whether they are running incorporated or unincorporated enterprises. The recent growth in Indigenous owner–managers is almost entirely in urban areas and cities where well-developed and diverse labour and product markets operate. The paper explores some of the key factors that are impacting on Indigenous business development, including issues about the economics of discrimination and remoteness. The paper also outlines policy implications that arise from the analysis. We reflect on further refinements of the Indigenous Procurement Policy, the recently announced Indigenous Business Sector Strategy and other policy options

Image-based Quantification of 3D Morphology for Bifurcations in the Left Coronary Artery: Application to Stent Design

Background Improved strategies for stent‐based treatment of coronary artery disease at bifurcations require a greater understanding of artery morphology. Objective We developed a workflow to quantify morphology in the left main coronary (LMCA), left anterior descending (LAD), and left circumflex (LCX) artery bifurcations. Methods Computational models of each bifurcation were created for 55 patients using computed tomography images in 3D segmentation software. Metrics including cross‐sectional area, length, eccentricity, taper, curvature, planarity, branching law parameters, and bifurcation angles were assessed using open‐sources software and custom applications. Geometric characterization was performed by comparison of means, correlation, and linear discriminant analysis (LDA). Results Differences between metrics suggest dedicated or multistent approaches should be tailored for each bifurcation. For example, the side branch of the LCX (i.e., obtuse marginal; OM) was longer than that of the LMCA (i.e., LCXprox) and LAD (i.e., first diagonal; D1). Bifurcation metrics for some locations (e.g., LMCA Finet ratio) provide results and confidence intervals agreeing with prior findings, while revised metric values are presented for others (e.g., LAD and LCX). LDA revealed several metrics that differentiate between artery locations (e.g., LMCA vs. D1, LMCA vs. OM, LADprox vs. D1, and LCXprox vs. D1). Conclusions These results provide a foundation for elucidating common parameters from healthy coronary arteries and could be leveraged in the future for treating diseased arteries. Collectively the current results may ultimately be used for design iterations that improve outcomes following implantation of future dedicated bifurcation stents

The importance of understanding Indigenous employment in the Indigenous business sector

Indigenous employment has been the subject of numerous policies in Australia, with governments aiming to increase the workforce participation rate amongst Indigenous people in recent years. Indigenous-owned businesses, formally defined as businesses that are at least 50% Indigenous-owned, have been demonstrated in previous research to maintain substantially higher levels of proportional Indigenous employment than non-Indigenous businesses. This suggests that Indigenous-owned businesses maintain work environments that are more supportive of and conducive to Indigenous employment, meriting the influence of Indigenous-owned businesses' workplace practices in future Indigenous employment policy design. Using administrative data from two Indigenous business registries (Black Business Finder and Supply Nation), this paper provides an updated empirical analysis of the Indigenous business sector. This paper demonstrates that Indigenous-owned businesses of all sizes, industries, locations and profit statuses consistently average proportional Indigenous employment rates higher than the Indigenous proportional population. Of all the people employed in Supply Nation-listed businesses, over 35% are Indigenous. The potential impact of the Indigenous Procurement Policy is illustrated by differentials in the size of businesses and their capacity to employ Indigenous staff. This paper provides analysis of the Indigenous business sector that can inform future policy direction for both Indigenous employment and Indigenous business policies. © 2023 The Authors.

CT Automated Exposure Control Using A Generalized Detectability Index

Purpose Identifying an appropriate tube current setting can be challenging when using iterative reconstruction due to the varying relationship between spatial resolution, contrast, noise, and dose across different algorithms. This study developed and investigated the application of a generalized detectability index (d\u27gen) to determine the noise parameter to input to existing automated exposure control (AEC) systems to provide consistent image quality (IQ) across different reconstruction approaches. Methods This study proposes a task‐based automated exposure control (AEC) method using a generalized detectability index (d\u27gen). The proposed method leverages existing AEC methods that are based on a prescribed noise level. The generalized d\u27gen metric is calculated using lookup tables of task‐based modulation transfer function (MTF) and noise power spectrum (NPS). To generate the lookup tables, the American College of Radiology CT accreditation phantom was scanned on a multidetector CT scanner (Revolution CT, GE Healthcare) at 120 kV and tube current varied manually from 20 to 240 mAs. Images were reconstructed using a reference reconstruction algorithm and four levels of an in‐house iterative reconstruction algorithm with different regularization strengths (IR1–IR4). The task‐based MTF and NPS were estimated from the measured images to create lookup tables of scaling factors that convert between d\u27gen and noise standard deviation. The performance of the proposed d\u27gen‐AEC method in providing a desired IQ level over a range of iterative reconstruction algorithms was evaluated using the American College of Radiology (ACR) phantom with elliptical shell and using a human reader evaluation on anthropomorphic phantom images. Results The study of the ACR phantom with elliptical shell demonstrated reasonable agreement between the d\u27gen predicted by the lookup table and d\u27 measured in the images, with a mean absolute error of 15% across all dose levels and maximum error of 45% at the lowest dose level with the elliptical shell. For the anthropomorphic phantom study, the mean reader scores for images resulting from the d\u27gen‐AEC method were 3.3 (reference image), 3.5 (IR1), 3.6 (IR2), 3.5 (IR3), and 2.2 (IR4). When using the d\u27gen‐AEC method, the observers’ IQ scores for the reference reconstruction were statistical equivalent to the scores for IR1, IR2, and IR3 iterative reconstructions (P \u3e 0.35). The d\u27gen‐AEC method achieved this equivalent IQ at lower dose for the IR scans compared to the reference scans. Conclusions A novel AEC method, based on a generalized detectability index, was investigated. The proposed method can be used with some existing AEC systems to derive the tube current profile for iterative reconstruction algorithms. The results provide preliminary evidence that the proposed d\u27gen‐AEC can produce similar IQ across different iterative reconstruction approaches at different dose levels
