High Muscle Mitochondrial Volume And Aerobic Capacity In A Small Marsupial (Sminthopsis Crassicaudata) Reveals Flexible Links Between Energy-Use Levels In Mammals, Terence Dawson, Koa Webster, Enhua Lee, William A. Buttemer
High Muscle Mitochondrial Volume And Aerobic Capacity In A Small Marsupial (Sminthopsis Crassicaudata) Reveals Flexible Links Between Energy-Use Levels In Mammals, Terence Dawson, Koa Webster, Enhua Lee, William A. Buttemer
Faculty of Science, Medicine and Health - Papers: part A
We investigated the muscle structure–function relationships that underlie the aerobic capacity of an insectivorous, small (~15 g) marsupial, Sminthopsis crassicaudata (Family: Dasyuridae), to obtain further insight into energy use patterns in marsupials relative to those in placentals, their sister clade within the Theria (advanced mammals). Disparate hopping marsupials (Suborder Macropodiformes), a kangaroo (Macropus rufus) and a rat-kangaroo (Bettongia penicillata), show aerobic capabilities as high as those of ‘athletic’ placentals. Equivalent muscle mitochondrial volumes and cardiovascular features support these capabilities. We examined S. crassicaudata to determine whether highly developed aerobic capabilities occur elsewhere in marsupials, rather than being restricted to the …

[1] The goal of this study is to determine how H2O and HDO measurements in water vapor can be used to detect and diagnose biases in the representation of processes controlling tropospheric humidity in atmospheric general circulation models (GCMs). We analyze a large number of isotopic data sets (four satellite, sixteen ground-based remote-sensing, five surface in situ and three aircraft data sets) that are sensitive to different altitudes throughout the free troposphere. Despite significant differences between data sets, we identify some observed HDO/H2O characteristics that are robust across data sets and that can be used to evaluate models. We evaluate …

The most prominent theory to explain the curvilinear relationship between income and subjective well-being (SWB) is need theory, which proposes that increased income and wealth can lead to increased well-being in poverty because money is used to satisfy basic physiological needs. The present study tests the tenets of need theory by proposing that money can buy happiness beyond poverty if the money satisfies higher-order needs. Findings indicate that in older adults (n = 1,284), as economic standing rises, so do individual perceptions of financial security (a safety need), which in turn increases overall life satisfaction. Further, a path model tested …

"This paper examined whether work-to-family interference (WFI) and work-to-family enhancement (WFE) mediated the association between job demands/control and self-reported mental and physical health. Data were from the Household, Income and Labor Dynamics in Australia survey and included 1,404 Australian adults aged 18-64 years at baseline; 820 participants provided data at three time points (baseline, 12-month follow-up, and 24-month follow-up). Self-report questionnaires assessed mental and physical health, WFI and WFE, and job demands/control. Mediation analyzes performed on the longitudinal data indicated that WFI mediated the relationships between job demands/control and self-reported mental and physical health. The findings have implications for improving …

BACKGROUND: Low-glycemic index (low-GI) diets may be less nutritious because of limited food choices. Alternately, high-GI diets could be less healthful because of a higher intake of refined carbohydrate. OBJECTIVE: The objective was to investigate the association between dietary GI, intakes of carbohydrates from high-GI (CHO(high GI)) and low-GI (CHO(low GI)) sources, and the risk of nutrient inadequacy in children and adolescents. DESIGN: Children, aged 2-16 y, who provided 2 plausible 24-h recalls in a national survey were included (n = 4140). The ORs of not meeting the Australian Nutrient Reference Values (NRVs) were calculated by logistic regression. RESULTS: Subjects …

Generally, sigmoid curves are used to describe the growth of animals over their lifetime. However, because growth rates often differ over an animal's lifetime a single curve may not accurately capture the growth. Broken-stick models constrained to pass through a common point have been proposed to describe the different growth phases, but these are often unsatisfactory because essentially there are still two functions that describe the lifetime growth. To provide a single, converged model to age animals with disparate growth phases we developed a smoothly joining two-phase nonlinear function (SJ2P), tailored to provide a more accurate description of lifetime growth …
Study Of The Relationship Between Infrared Stimulated Luminescence And Blue Light Stimulated Luminescence For Potassium-Feldspar From Sediments, Zhijun Gong, Bo Li, Sheng-Hua Li
Study Of The Relationship Between Infrared Stimulated Luminescence And Blue Light Stimulated Luminescence For Potassium-Feldspar From Sediments, Zhijun Gong, Bo Li, Sheng-Hua Li

In luminescence measurements of potassium-feldspar (K-feldspar), both infrared (IR) and blue light (BL) can be used as stimulation sources. Component analysis suggests that the blue light stimulated luminescence (BLSL) measured at 60 °C from K-feldspar can be fitted using three components, namely fast, medium and slow. In order to explore the relationship between the origin of the infrared stimulated luminescence (IRSL) signal and the different components of the BLSL, five sets of experiments were conducted, namely post-IR BLSL (pIR-BLSL), post-BL IRSL (pBL-IRSL), pulse annealing tests, dose response and laboratory fading rate tests. It is observed that most of the IRSL …

The present study examined associations between food marketing exposure and adolescents’ food choices and reported consumption of energy-dense and nutrient-poor (EDNP) foods. A cross-sectional survey of 12,188 Australian secondary students aged 12–17 years was conducted, using a web-based self-report questionnaire. Measures included students’ level of exposure to commercial television and non-broadcast types of food marketing, whether they had tried a new product or requested a product they had seen advertised, and their reported consumption of fast food, sugary drinks and sweet and salty snacks. Results indicated greater exposure to commercial television, print/transport/school food marketing and digital food marketing were all …

The importance of student motivation within a student's educational career can be viewed as a cornerstone to effective pedagogy and student learning. Xiang, Lee and Shen (2001) have indicated that as student's progress throughout the K-12 system, their level of motivation tends to decrease. As such, a question of intrigue is whether teachers within different grade levels provide different motivational instruction. Therefore, the purpose of this study was to examine the differences between primary and secondary educators ability to provide a motivationally-supportive learning context. Grounded within the self-determination theory (SDT; Deci & Ryan, 1985), this study utilized a quantitative approach …

Populations in Southern China (Bai-yue) and Borneo (Bidayuh) with high incidence of nasopharyngeal cancer(NPC) share similar mitochondrial DNA signatures, supporting the hypothesis that these two populations may share the same genetic predisposition for NPC, which may have first appeared in a common ancestral reference population before the sea levels rose after the last ice age.
Dissociation Mediates The Relationship Between Childhood Trauma And Hallucination-Proneness., F Varese, E Barkus, R P. Bentall
Dissociation Mediates The Relationship Between Childhood Trauma And Hallucination-Proneness., F Varese, E Barkus, R P. Bentall
Faculty of Health and Behavioural Sciences - Papers (Archive)
BACKGROUND: It has been proposed that the relationship between childhood trauma and hallucinations can be explained by dissociative processes. The present study examined whether the effect of childhood trauma on hallucination-proneness is mediated by dissociative tendencies. In addition, the influence of dissociative symptoms on a cognitive process believed to underlie hallucinatory experiences (i.e. reality discrimination; the capacity to discriminate between internal and external cognitive events) was also investigated.MethodPatients with schizophrenia spectrum disorders (n=45) and healthy controls (with no history of hallucinations; n=20) completed questionnaire measures of hallucination-proneness, dissociative tendencies and childhood trauma, as well as performing an auditory signal detection …
Interest Rate Pass Through And The Asymmetric Relationship Between The Cash Rate And The Mortgage Rate, Abbas Valadkhani, Sajid Anwar
Interest Rate Pass Through And The Asymmetric Relationship Between The Cash Rate And The Mortgage Rate, Abbas Valadkhani, Sajid Anwar

There is an ongoing controversy over whether banks’ mortgage rates rise more rapidly than they fall due to their asymmetric responses to changes in the cash rate. This paper examines the dynamic interplay between the cash rate and the standardvariable mortgage rate using monthly data in the post-1989 era. Unlike previous Australian studies, our proposed threshold and asymmetric error-correction models account for both the amount and adjustment asymmetries. We found that the Reserve Bank of Australia’s rate rises have a much larger and more instantaneous impact on the mortgage rate than rate cuts.

Recombination is typically assumed to be absent in animal mitochondrial genomes (mtDNA). However, the maternal mode of inheritance means that recombinant products are indistinguishable from their progenitor molecules. The majority of studies of mtDNA recombination assess past recombination events, where patterns of recombination are inferred by comparing the mtDNA of different individuals. Few studies assess contemporary mtDNA recombination, where recombinant molecules are observed as direct mosaics of known progenitor molecules. Here we use the potato cyst nematode, Globodera pallida, to investigate past and contemporary recombination. Past recombination was assessed within and between populations of G. pallida, and contemporary …
