Effective CALD community health communication through research and collaboration: An exemplar case study
Health communication is identified as an important strategy in achieving health outcomes, particularly in supporting preventative approaches to combatting disease and ill-health. In Australiaâs multicultural society, health communication needs to address a number of CALD communities in order to achieve health objectives and social equity. While cross-cultural and intercultural communication have been widely studied, research shows that health communication often fails to achieve its objectives, particularly in CALD communities. This analysis examines a case study that highlights three key ingredients of effective health communication targeting CALD communities â in-depth qualitative formative research, a collaborative community-based approach, and cultural competency. The case study reveals how a culture-centred approach (CDA) and social ecology model of health communication achieved results that exceeded targets by up to 100% on a relatively small budget, but also revealed gaps in cultural competency that disadvantage some groups. This study contributes to health communication theory and practice, as well as public communication generally, by providing insights into ways to increase effectiveness as well as cost-efficiency, which in turn creates scalability and sustainability
PR and Communication Management in Asia-Pacific: Trends, Growth and Gaps
With a number of Asia-Pacific countries among the fastest growing in the world, the requirements for public relations and communication management are also growing in terms of both demand and professionalism. It is essential that practitioners and academics keep pace with demand and achieve âinternational best practiceâ. In 2015/16, the largest ever survey of PR and communication management in Asia-Pacific was launched as a biannual study, with the second survey undertaken in 2017/18. The survey is modelled on similar studies that have been conducted in Europe since 2007, in Latin American since 2014, and North America from 2018, allowing international comparison. This analysis examines key findings of the latest Asia-Pacific survey and compares results with the 2015/16 Asia-Pacific study as well as with international data to identify trends, areas of growth in professional practice, and gaps and shortcomings to be addressed. The findings are informative for educators, professional associations, and practitioners in terms of the design of undergraduate and graduate courses and ongoing training and professional development
Is swimming safe in heart failure? : a systematic review
It is not clear whether swimming is safe in patients with chronic heart failure. Ten studies examining the hemodynamic effects of acute water immersion (WI) (155 patients; average age 60 years; 86% male; mean left ventricular ejection fraction (LVEF) 29%) and 6 randomized controlled trials of rehabilitation comparing swimming with either medical treatment only (n = 3) or cycling (n = 1) or aerobic exercise (n = 2), (136 patients, average age 59 years; 84% male, mean LVEF 31%) were considered. In 7 studies of warm WI (30â35°C): heart rate (HR) fell (2% to â15%), and both cardiac output (CO) (7â37%) and stroke volume (SV) increased (13â41%). In 1 study of hot WI (41°C), systemic vascular resistance (SVR) fell (41%) and HR increased (33%). In 2 studies of cold WI (12â22°C), there were no consistent effects on HR and CO. Compared with medical management, swimming led to a greater increase in peak Voâ (7â14%) and 6 minute walk test (6MWT) (7â13%). Compared with cycle training, combined swimming and cycle training led to a greater reduction in resting HR (16%), a greater increase in resting SV (23%) and SVR (15%), but no changes in resting CO and a lesser increase in peak Voâ (6%). Compared with aerobic training, combined swimming and aerobic training lead to a reduction in resting HR (19%) and SVR (54%) and a greater increase in SV (34%), resting CO (28%), LVEF (9%), and 6MWT (70%). Although swimming appears to be safe, the studies conducted have been small, very heterogeneous, and inconclusive
Multilingual gendered identities: female undergraduate students in London talk about heritage languages
In this paper I explore how a group of female university students, mostly British Asian and in their late teens and early twenties, perform femininities in talk about heritage languages. I argue that analysis of this talk reveals ways in which the participants enact âculturally intelligibleâ gendered subject positions. This frequently involves negotiating the norms of âheteronormativityâ, constituting femininity in terms of marriage, motherhood and maintenance of heritage culture and language, and âgirl powerâ, constituting femininity in terms of youth, sassiness, glamour and individualism. For these young women, I ask whether higher education can become a site in which they have the opportunities to explore these identifications and examine other ways of imagining the self and what their stories suggest about âdoing beingâ a young British Asian woman in London
Changes in frequency and location of east coast low pressure systems affecting southeast Australia
Low pressure systems off the southeast coast of Australia can generate intense rainfall and associated flooding, destructive winds, and coastal erosion, particularly during the cool season (AprilâSeptember). Impacts depend on coastal proximity, strength and latitude. Therefore, it is important to investigate changes in frequency, duration, location, and intensity of these systems. First, an existing observationâbased database of these low pressure systems, for 1970â2006, is extended to 2019, focusing on AprilâSeptember and using archived Australian Bureau of Meteorology MSLP charts. Second, data consistency between 1970 and 2006 and 2007 and 2019 is confirmed. Third, permutation testing is performed on differences in means and variances between the two 25âyear intervals 1970â1994 and 1995â2019. Additionally, trends in positions, durations and central pressures of the systems are investigated. pâvalues from permutation tests reveal statistically significant increases in mean low pressure system frequencies. Specifically, a greater frequency of both total days and initial development days only, occurred in the latter period. Statistically significant lower variance for both latitude and longitude in systems that developed in both subtropical easterly and midâlatitude westerly wind regimes indicate a shift south and east in the latter period. Furthermore, statistically significant differences in variance of development location of explosive low pressure systems that develop in a low level easterly wind regime indicate a shift further south and east. These changes are consistent with fewer systems projected to impact the east coast. Finally, important changes are suggested in the large scale atmospheric dynamics of the eastern Australian/Tasman Sea region
Attribution and Prediction of Precipitation and Temperature Trends within the Sydney Catchment Using Machine Learning
Droughts in southeastern Australia can profoundly affect the water supply to Sydney, Australiaâs largest city. Increasing population, a warming climate, land surface changes and expanded agricultural use increase water demand and reduce catchment runoff. Studying Sydneyâs water supply is necessary to manage water resources and lower the risk of severe water shortages. This study aims at understanding Sydneyâs water supply by analysing precipitation and temperature trends across the catchment. A decreasing trend in annual precipitation was found across the Sydney catchment area. Annual precipitation also is significantly less variable, due to fewer years above the 80th percentile. These trends result from significant reductions in precipitation during spring and autumn, especially over the last 20 years. Wavelet analysis was applied to assess how the influence of climate drivers has changed over time. Attribute selection was carried out using linear regression and machine learning techniques, including random forests and support vector regression. Drivers of annual precipitation included Niño3.4, Southern Annular Mode (SAM) and DMI, and measures of global warming such as the Tasman Sea sea surface temperature anomalies. The support vector regression model with a polynomial kernel achieved correlations of 0.921 and a skill score compared to climatology of 0.721. The linear regression model also performed well with a correlation of 0.815 and skill score of 0.567, highlighting the importance of considering both linear and non-linear methods when developing statistical models. Models were also developed on autumn and winter precipitation but performed worse than annual precipitation on prediction. For example, the best performing model on autumn precipitation, which accounts for approximately one quarter of annual precipitation, achieved an RMSE of 418.036 mm2 on the testing data, while annual precipitation achieved an RMSE of 613.704 mm2. However, the seasonal models provided valuable insights into whether the season would be wet or dry compared to the climatology.</jats:p

The illusion of competency versus the desirability of expertise: Seeking a common standard for support professions in sport
In this paper we examine and challenge the competency-based models which currently dominate accreditation and development systems in sport support disciplines, largely the sciences and coaching. Through consideration of exemplar shortcomings, the limitations of competency-based systems are presented as failing to cater for the complexity of decision making and the need for proactive experimentation essential to effective practice. To provide a better fit with the challenges of the various disciplines in their work with performers, an alternative approach is presented which focuses on the promotion, evaluation and elaboration of expertise. Such an approach resonates with important characteristics of professions, whilst also providing for the essential âshades of greyâ inherent in work with human participants. Key differences between the approaches are considered through exemplars of evaluation processes. The expertise-focused method, although inherently more complex, is seen as offering a less ambiguous and more positive route, both through more accurate representation of essential professional competence and through facilitation of future growth in proficiency and evolution of expertise in practice. Examples from the literature are also presented, offering further support for the practicalities of this approach
Transient Activation of Hematopoietic Stem and Progenitor Cells by IFNÎł during Acute Bacterial Infection
How hematopoietic stem cells (HSCs) respond to inflammatory signals during infections is not well understood. Our studies have used a murine model of ehrlichiosis, an emerging tick-born disease, to address how infection impacts hematopoietic function. Infection of C57BL/6 mice with the intracellular bacterium, Ehrlichia muris, results in anemia and thrombocytopenia, similar to what is observed in human ehrlichiosis patients. In the mouse, infection promotes myelopoiesis, a process that is critically dependent on interferon gamma (IFNÎł) signaling. In the present study, we demonstrate that E. muris infection also drives the transient proliferation and expansion of bone marrow Lin-negative Sca-1+ cKit+ (LSK) cells, a population of progenitor cells that contains HSCs. Expansion of the LSK population in the bone marrow was associated with a loss of dormant, long-term repopulating HSCs, reduced engraftment, and a bias towards myeloid lineage differentiation within that population. The reduced engraftment and myeloid bias of the infection-induced LSK cells was transient, and was most pronounced on day 8 post-infection. The infection-induced changes were accompanied by an expansion of more differentiated multipotent progenitor cells, and required IFNÎł signaling. Thus, in response to inflammatory signals elicited during acute infection, HSCs can undergo a rapid, IFNÎł-dependent, transient shift from dormancy to activity, ostensibly, to provide the host with additional or better-armed innate cells for host defense. Similar changes in hematopoietic function likely underlie many different infections of public health importance
Understanding the process of psychological development in youth athletes attending an intensive wrestling camp
This study used a grounded theory methodology to understand if and how psychological development in youth athletes was facilitated by an âintensiveâ summer wrestling camp experience. The theoretical sampling approach involved 10 athlete participants of the camp, nine parents of athletes, the director of the camp, and four camp staff members, who took part in a series of interviews before, during, and after the camp. Two researchers were also embedded in the camp and attended all sessions, took detailed notes, collected camp materials, and conducted observations. Following a grounded theory analysis approach, a model is presented that outlines how youth participantsâ developed psychological qualities from the coach created hallenges and adversity that were systematically designed to facilitate sport performance enhancement and life skills. Variations emerged in psychological antecedents and characteristics, how the challenging wrestling camp environment was interpreted and experienced, and how learning was transferred to sport and life domains outside of the wrestling camp. This study provided insight into a unique youth sport context that was able to simultaneously develop psychological qualities to be used as sport performance enhancement and life skills
