Does Sustainability Engagement Affect Stock Return Volatility? Evidence From The Chinese Financial Market, Junru Zhang, Harian G. Djajadikerta, Zhaoyong Zhang Prof

Research outputs 2014 to 2021

This paper examines the impact of firms’ sustainability engagement on their stock returns and volatility by employing the EGARCH and FIGARCH models using data from the major financial firms listed in the Chinese stock market. We find evidence of a positive association between sustainability engagement and stock returns, suggesting firms’ sustainability news release in favour of the market. Although volatility persistence can largely be explained by news flows, the results show that sustainability news release has the significant and largest drop in volatility persistence, followed by popularity in Google search engine and the general news. Sustainability news release is found …

The environment scaffolded reflection through (1) exemplars of good practice, (2) the opportunity for discussions and (3) activities to support the development of reflection. There were issues within the research around the introduction of the platform at the particular stage of the students’ degrees but the environment was successful in the provision of a teaching and learning platform. The findings provided design principles for a model to guide the development …

Reimagining The Cultural Significance Of Wetlands: From Perth’S Lost Swamps To The Beeliar Wetlands, Danielle Brady, Jeffrey Murray

Research outputs 2014 to 2021

The history of Perth, Western Australia, has been characterised by the incremental loss of its wetlands. While disputes about wetlands are often framed solely in terms of the environment, they are places of cultural significance too. The extensive wetlands of central Perth, food gathering and meeting places for Noongar people are now expunged from the landscape. Urban dwellers of Perth are largely unaware that the seasonal lakes and wetlands of the centre of the city were the larders, gardens, hideouts, dumps and playgrounds of previous generations; both Noongar and Settler. The loss of social memory of these lost cultural/natural places …

The Fourth Industrial Revolution: The Implications Of Technological Disruption For Australian Vet, Pi-Shen Seet, Janice Jones, John Spoehr, Ann-Louise Hordacre

Research outputs 2014 to 2021

Much discussion has occurred about the impact that technological disruption will have on the Australian workforce. A recent paper by the National Centre for Vocational Education Research (NCVER), Skilling for tomorrow (Payton 2017), examines the various ways by which the growth in technological advance is reshaping the labour market, workforce and jobs. Despite uncertainty about the scale and nature of the effect, there is a growing consensus that Australia’s tertiary education system needs to change to meet the requirements of a future labour force focused on innovation and creativity. This research examines the relationship between emerging ─ or disruptive ─ …

Evaluating An Analytical Model To Predict Subsurface Lnapl Distributions And Transmissivity From Current And Historic Fluid Levels In Groundwater Wells: Comparing Results To Numerical Simulations, Robert J. Lenhard, Kaveh Sookhak Lari, John L. Rayner, Greg B. Davis

Research outputs 2014 to 2021

A recent analytical model predicts free, entrapped, and residual LNAPL saturations and the LNAPL transmissivity in the subsurface from current and historic fluid levels in groundwater wells. As such, the model accounts for effects of fluid level fluctuations in a well. The model was developed to predict LNAPL specific volumes and transmissivities from current fluid level measurements in wells and either recorded historic fluid level fluctuations in wells or estimates. An assumption is made in the model that the predictions are not dependent on whether the historic highest or lowest fluid level elevations in a well occur first. To test …

Print Versus Digital Preferences Of University Students In Australia, Nicole Johnston, A.M. Salaz

Research outputs 2014 to 2021

This paper presents findings of a survey that investigated the reading preferences of university students at Edith Cowan University (ECU) in Perth, Australia. This survey is being undertaken as part of the Academic Reading Format International Study (ARFIS), which is investigating print versus digital reading preferences in 31 countries. A total of 582 students completed the survey. Results from the survey indicate a strong preference for reading in print because of issues such as eyestrain, tactile features, better focus, and ability to highlight and take notes. Issues such as cost, usability and accessibility also impacted on students’ reading decisions.

‘Team Australia?’: Understanding Acculturation From Multiple Perspectives, Justine Dandy, Tehereh Zianian, Carolyn Moylan

Research outputs 2014 to 2021

In this paper we explore mutual acculturation among Australians from Indigenous, majority, immigrant and refugee backgrounds. Our aims were: to develop Berry’s acculturation scales for use in Australia and from multiple perspectives and to explore acculturation expectations and strategies from these multiple perspectives. We conducted in-depth interviews (n = 38) in Perth, Western Australia. We investigated participants’ views, guided by the two dimensions underlying Berry’s model of acculturation: cultural maintenance and intercultural contact, and models of culture learning. We found that participants had different acculturation expectations for different groups, as well as different preferred strategies for themselves, although most …

Remobilization Of Heavy Metals By Mangrove Leaves, Hanan Almahasheer, Oscar Serrano, Carlos M. Duarte, Xabier Irigoien

Research outputs 2014 to 2021

Several studies have been carried out on heavy metal pollution in mangrove ecosystems. However, the role of mangroves in heavy metal remobilization is still relatively unknown. On one side, mangrove woody organs and soils sequester heavy metals for long time periods, but on the other hand, senescence of mangrove leaves may return these metals collected by roots to the upper layers of the soil. Here, we analyzed the concentration of chemical elements (Al, As, Cd, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Sr, V, and Zn) as a function of age in mangrove leaves to understand heavy metals retention by …

Using Nvivo™ For Literature Reviews: The Eight Step Pedagogy (N7+1), Maureen M. O'Neill, Sarah R. Booth, Janeen Therese Lamb

Research outputs 2014 to 2021

While a literature review is a necessary milestone to be completed by all researchers in a timely and efficient manner, it is often one of the most difficult aspects of the research journey. Moreover, traditional approaches often leave novice researchers, to struggle with the conceptualisation of their literature review, now complicated by the overwhelming quantity of research available online. This paper presents a rationale the use of Qualitative Data Analysis Software (QDAS) programs for literature reviews. QDAS tools allow the researcher to explore large amounts of textual documents to see patterns. These programs are often overlooked by novice researchers due …

Because NITARP has been running since 2009, and its predecessor ran from 2005-2008, there have been many …

Characterizing The Metabolic Intensity And Cardiovascular Demands Of Walking Football In Southeast Asian Women, D. P. Heil, Robert U. Newton, Dee Dee Ayra Salle

Research outputs 2014 to 2021

Given that the recent rise in obesity rates throughout Southeast Asia is disproportionately driven by women, part of the regional solution may be to encourage more habitual physical activity within this population. Taking advantage of the regional popularity of walking football, this study sought to characterize the cardiovascular demands and metabolic intensity of Southeast Asian women competing in walking football matches to determine the sports’ suitability for promoting physical health. It was hypothesized that both cardiovascular and metabolic intensity measures (≥65% HR% and ≥3.0 METs, respectively) would meet or exceed established thresholds for improving fitness and health. Methods: Women’s teams …

The Continuance Intention Of User’S Engagement In Multiplayer Video Games Based On Uses And Gratifications Theory, Ira Puspitasari, Elzha Odie Syahputra, Indra Kharisma Raharjana, Ferry Jie

Research outputs 2014 to 2021

One of the key success factors in video game industry, including multiplayer video game (MVG), is the user’s continuance intention. The MVG industry runs in a highly competitive market. Users can shift to another game as soon as they discover a slightly inconvenient issue. Thus, maintaining the user’s enthusiasm in playing MVG for a long time is challenging for most games. The solution to prolong the users’ engagement can be initiated by identifying all factors that facilitate the continuance use of playing MVG. This study applied uses and gratifications theory to examine seven variables (enjoyment, fantasy, escapism, social interaction, social …

Do Nonparametric Measures Of Extreme Equity Risk Change The Parametric Ordinal Ranking? Evidence From Asia, Robert J. Powell, Duc H. Vo., Thach N. Pham

Research outputs 2014 to 2021

There has been much discussion in the literature about how central measures of equity risk such as standard deviation fail to account for extreme tail risk of equities. Similarly, parametric measures of value at risk (VaR) may also fail to account for extreme risk as they assume a normal distribution which is often not the case in practice. Nonparametric measures of extreme risk such as nonparametric VaR and conditional value at risk (CVaR) have often been found to overcome this problem by measuring actual tail risk without applying any predetermined assumptions. However, this article argues that it is not just …

Are Current Effectiveness Criteria Fit For Purpose? Using A Controversial Strategic Assessment As A Test Case, Jenny Pope, Alan J. Bond, Carolyn Cameron, François P. Retief, Angus N. Morrison-Saunders

Research outputs 2014 to 2021

The aim of this paper is to test the broader utility of the sustainability assessment effectiveness framework of Bond et al. (2015) by applying it to a controversial strategic assessment case study. The effectiveness framework comprises six dimensions: procedural effectiveness, substantive effectiveness, transactive effectiveness, normative effectiveness, pluralism, and knowledge and learning. It was originally developed to evaluate sustainability assessment at a system-wide level and it has not been previously applied to a specific case study. The analysis was conducted through document review and the first-hand experience of two of the authors who were involved in the case study …

How Does Destination Social Responsibility Contribute To Environmentally Responsible Behaviour? A Destination Resident Perspective, Lujun Su, Songshan (Sam) Huang, Joanna Pearce

Research outputs 2014 to 2021

Based on stakeholder theory and social exchange theory, this study developed an integrated model to demonstrate that destination social responsibility (DSR) influences tourism impacts (both positive and negative impacts), overall community satisfaction, and both directly and indirectly influences resident environmentally responsible behaviour (ERB). The model was examined using a sample of 453 residents living on the Gulangyu Island, a famous island tourism destination of Xiamen, China. Results show that DSR enhances residents’ perception of positive tourism impacts, improves overall community satisfaction and contributes to resident ERB. However, the effect of DSR on negative tourism impacts was not significant. Thus, positive …

Towards An Improved Typology Approach To Segmenting Cultural Tourists, Ganghua Chen, Songshan (Sam) Huang

Research outputs 2014 to 2021

This study aims to improve the cultural tourist typology methodology that uses cultural centrality and depth of cultural experience in its framework. Using a sample of Chinese tourists in Macau (n = 595) collected via questionnaire surveys, the study confirmed the determination effect of cultural centrality on depth of cultural experience. Subsequently, the study demonstrated an improved approach that eliminates such a determination effect in typology identification. Compared to McKercher's () approach, the improved typology presents a balanced segmentation of cultural tourists and distinguishes the segments more clearly in their sociodemographic characteristics. The improved typology generated more meaningful practical implications.

Metabolic And Fatigue Profiles Are Comparable Between Prepubertal Children And Well-Trained Adult Endurance Athletes, Anthony Birat, Pierre Bourdier, Enzo Piponnier, Anthony J. Blazevich, Hugo Maciejewski, Pascale Duche, Sebastien Ratel

Research outputs 2014 to 2021

The aim of this study was to determine whether prepubertal children are metabolically comparable to well-trained adult endurance athletes and if this translates into similar fatigue rates during high-intensity exercise in both populations. On two different occasions, 12 prepubertal boys (10.5 ± 1.1 y), 12 untrained men (21.2 ± 1.5 y), and 13 endurance male athletes (21.5 ± 2.7 y) completed an incremental test to determine the power output at VO_2max (PVO_2max) and a Wingate test to evaluate the maximal anaerobic power (P_max) and relative decrement in power output (i.e., the fatigue index, FI). Furthermore, …

Ward, Richard L. Prince, Joshua R. Lewis, Amanda Devine, Kevin D. Croft, Jonathan M. Hodgson, Catherine P. Bondonno

Research outputs 2014 to 2021

Background

Dietary nitrate is an important source of nitric oxide (NO), a molecule critical for cardiovascular health. Nitrate is sequentially reduced to NO through an enterosalivary nitrate-nitrite-NO pathway that involves the oral microbiome. This pathway is considered an important adjunct pathway to the classical l-arginine–NO synthase pathway.

Objective

The objective of this study was to systematically assess the evidence for dietary nitrate intake and improved cardiovascular health from both human and animal studies.

Design

A systematic literature search was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines by using key search terms in Medline and …

Research outputs 2014 to 2021

Seagrass ecosystems contain globally significant organic carbon (C) stocks. However, climate change and increasing frequency of extreme events threaten their preservation. Shark Bay, Western Australia, has the largest C stock reported for a seagrass ecosystem, containing up to 1.3% of the total C stored within the top metre of seagrass sediments worldwide. On the basis of field studies and satellite imagery, we estimate that 36% of Shark Bay’s seagrass meadows were damaged following a marine heatwave in 2010/2011. Assuming that 10 to 50% of the seagrass sediment C stock was exposed to oxic conditions after disturbance, between 2 and 9 …

Cardiovascular Health Benefits Of Specific Vegetable Types: A Narrative Review, Lauren C. Blekkenhorst, Marc Sim, Catherine P. Bondonno, Nicola Bondonno, Natalie Ward, Richard Prince, Amanda Devine, Joshua Lewis, Jonathan M. Hodgson

Research outputs 2014 to 2021

Adequate vegetable consumption is one of the cornerstones of a healthy diet. The recommendation to increase vegetable intake is part of most dietary guidelines. Despite widespread and long-running public health messages to increase vegetable intake, similar to other countries worldwide, less than 1 in 10 adult Australians manage to meet target advice. Dietary guidelines are predominantly based on studies linking diets high in vegetables with lower risk of chronic diseases. Identifying vegetables with the strongest health benefits and incorporating these into dietary recommendations may enhance public health initiatives around vegetable intake. These enhanced public health initiatives would be targeted at …

Research outputs 2014 to 2021

Introduction: White matter hyperintensity (WMH) volume on MRI is increased among presymptomatic individuals with autosomal dominant mutations for Alzheimer’s disease (AD). One potential explanation is that WMH, conventionally considered a marker of cerebrovascular disease, are a reflection of cerebral amyloid angiopathy (CAA) and that increased WMH in this population is a manifestation of this vascular form of primary AD pathology. We examined whether the presence of cerebral microbleeds, a marker of CAA, mediates the relationship between WMH and estimated symptom onset in individuals with and without autosomal dominant mutations for AD.

Participants and methods: Participants (n = 175, …

The Psychometric Assessment Of Alexithymia: Development And Validation Of The Perth Alexithymia Questionnaire, David Preece, Rodrigo Becerra, Ken Robinson, Justine Dandy, Alfred Allan

Research outputs 2014 to 2021

Alexithymia is a trait comprising people's ability to focus attention on and accurately appraise their own emotions. Its assessment is of clinical interest because people who have difficulty processing their negative and positive emotions are more vulnerable to developing psychopathology symptoms, however, existing alexithymia measures cannot comprehensively assess the construct across both negative and positive emotions. In this paper, we attempt to remedy these measurement limitations by developing and validating a new 24-item self-report measure, the Perth Alexithymia Questionnaire (PAQ), which is based on the attention-appraisal model of alexithymia. In Study 1, our confirmatory factor analyses in a sample of …

Measuring Emotion Regulation Ability Across Negative And Positive Emotions: The Perth Emotion Regulation Competency Inventory (Perci), David Preece, Rodrigo Becerra, Ken Robinson, Justine K. Dandy, Alfred Allan

Research outputs 2014 to 2021

Emotion regulation problems underlie the abnormal levels of negative or positive emotion that characterise many forms of psychopathology. Several self-report measures of emotion regulation ability exist, but many are inconsistent with contemporary emotion regulation theory, and none comprehensively assess this construct across both negative and positive emotions. In this paper, we report our attempt to remedy these measurement limitations by developing and validating the Perth Emotion Regulation Competency Inventory (PERCI), a 32 item self-report questionnaire that measures emotion regulation ability as it is defined by the extended process model of emotion regulation. In Study 1, our confirmatory factor …
