  • Description: On 2018-01-17 two electron crystallography structures (with PDB entries 6AXZ, 6BTK) on a prion protofibril of bank vole PrP(168-176) (a segment in the PrP β2-α2 loop) were released into the PDB Bank. The paper published by Gallagher-Jones et al. (Nat Struct Mol Biol 25(2):131–134, 2018) reports some polar clasps for these two crystal structures, and “an intersheet hydrogen bond between Tyr169 and the backbone carbonyl of Asn171 on an opposing strand.”—this hydrogen bond is not directly between the neighboring chain B and chain A. In addition, by revisiting the polar clasps, we found another two hydrogen bonds (B.Asn171@H–A.Gln172@OE1, B.Tyr169@OH–A.Gln172@N) between the strand A of one sheet and the opposing strand B of the mating sheet. For the neighboring two single beta-sheets AB, the two new hydrogen bonds are completely different from the experimental one (an intersheet hydrogen bond between Tyr169 and the backbone carbonyl of Asn171 on an opposing strand) in (Nat Struct Mol Biol 25(2):131–134, 2018).

  • Description: Objective: Phobic anxiety is a risk factor for poor prognosis following Acute Coronary Syndrome (ACS). A psychophysiological marker of vagal function, autonomic dysfunction may play a critical role in this relationship. The aim of the study was two-fold: to assess whether phobic anxiety was characterised by autonomic dysfunction (heart rate variability) in the short (1-month) and longer term (12-months) following ACS, and (ii) to quantify the extent to which HRV parameters modified the effect of phobic anxiety on all-cause hospital readmission over 2 years. Methods: The ADVENT study followed 416 ACS patients. At 1-month following discharge (T0), phobic anxiety and autonomic functioning were assessed using the Crown Crisp Index (CCI) and 11 indices of heart rate variability (HRV), respectively. HRV was measured again at 12-months (T1) (n = 359). Hospital readmission (all cause) was derived from an audit of hospital records by two medically trained research fellows. Generalised linear modelling (GLM) was used to first determine the association between CCI score at T0 and HRV parameters at T0 and T1. Binary logistic regression was used to measure the relationship between CCI scores and readmission (yes/no) and the extent to which HRV parameters modified this effect. Results: CCI scores were associated with 7 of the 11 indices of HRV: Average RR (ms), SDRR (ms), RMSSD (ms), SDSD (ms), pRR50 (%), LF Powers (ms2) and HF Powers (ms2) at T0 but not T1. CCI scores at T0 significantly predicted likelihood of readmission to hospital in the subsequent 2 year period. No parameter of HRV at T0 modified this effect. Limitations: We were unable to provide adjudicated major adverse coronary events outcome data, or account for changes in medication adherence, diet or physical activity. Conclusions: While phobic anxiety is associated with both reduced vagal function in the short term after an ACS event and 2 year all cause readmission, HRV does not appear to be the pathway by which phobic anxiety drives this outcome.

  • Description: Livestock industries are increasingly embracing precision farming and decision support tools. As a result, sensors, weather stations, individual animal tracking, feed monitoring and other sources create large data volumes, much of which is used only for a single purpose. There are unrealised potential benefits of making on farm data interoperable and accessible and federating it with public data sources. We reviewed recent literature on precision livestock farming (PLF) technologies in relation to the use of public data, open standards and interoperability. Livestock farms produce rising volumes of disparate private datasets, reflecting a variety of information needs and technological opportunities, but typically lacking interoperable formats and metadata. These as well as large amounts of accessible public datasets are currently underutilised in decision support tools. Tools that demonstrate the use of interoperable standards and bring together public and private data for decision support can enhance the value proposition and help lower barriers to the sharing and re-use of data. This review of interoperable standards in extensive livestock farming systems concludes that there is a need for not only a new type of decision support tool, but also a consensus on data exchange standards to prove the value of shared data at farm scale (commercial benefit) and a regional scale (public good). © 2018

  • Description: Australia’s treatment of asylum seekers continues to polarise public debate. The present study sought to investigate the factors that may influence an individual’s endorsement of deterrence-based government policies. Using the integrated threat theory of prejudice, the present study examined the role of perceived threat in shaping Australian voters’ political attitudes toward asylum seekers. A total of 255 Australian citizens completed an online questionnaire that assessed their support for aspects of government policy and their perceptions of asylum seekers as a threat. Hierarchical multiple regression analyses were used to examine the combined and unique influences of perceived threat and sociodemographic factors on overall and individual government policy endorsement. Results indicated that various types of threat (realistic, symbolic, and negative stereotypes) were significant predictors of policy support. Practical implications regarding the development of anti-discriminatory strategies and directions for future research are discussed.

  • Description: Objectives: To determine the factors that influence physiotherapists’ choice to promote non-treatment physical activity to patients with musculoskeletal conditions. Design: Cross sectional survey. Methods: A national, online self report survey was targeted at Australian registered physiotherapists primarily treating patients with musculoskeletal conditions in private practice and outpatient settings. Likert scale questions were used to measure the factors influencing non-treatment physical activity promotion by physiotherapists. Results: Two hundred and sixteen full responses were received. Most (56.6%) respondents irregularly promoted non-treatment physical activity, whereas 43.4% always promoted non-treatment physical activity. Promotion of non-treatment physical activity was bivariately associated with respondents’ own physical activity level (x2[2] = 7.670, p = 0.022) and exercise science education (x2[1] = 4.613, p = 0.032). Multivariable analysis identified that Knowledge (knowing how to promote non-treatment physical activity) (OR = 1.60, 95%CI 1.026–2.502), Goals (other patient problems are more important) (OR = 0.62, 95%CI 0.424–0.897) and Innovation (compatibility of non-treatment physical activity promotion with the clinical environment) (OR = 1.75, 95%CI 1.027–2.985) were significantly and independently associated with non-treatment physical activity promotion. Conclusions: The majority of surveyed Australian physiotherapists irregularly promoted non-treatment physical activity. Lack of knowledge of how to promote non-treatment physical activity, prioritising other patient problems before non-treatment physical activity promotion and using promotion methods that are not compatible with current practice might reduce non-treatment physical activity promotion frequency by physiotherapists.

  • Description: Green bonds could play a key role in financing the investment needed to achieve the global climate and energy objectives and the UN Sustainable Development Goals. Using Bloomberg data of corporate green bond issuance from 2010 to 2017, we explore the factors affecting the size of borrowing. By employing a set of tri-dimensional elements (security characteristics, issuer characteristics, and market characteristics), we investigate the consistency of the effects across emerging and non-emerging markets. Findings suggest that, in general, issue size is positively related coupon rate, credit rating, collateral availability, and issuer’s sector and financial health. Moreover, issuances in emerging markets with a more international orientation and denominated in EURO, have a higher size. Arguably, these features make bonds more reliable, secured, and return-generating for investors, which facilitates higher issue size through greater investor demand. The paper calls for policies and incentives to encourage impact borrowing through increased green bond supply.

  • Description: Background: A recent meta-analysis left open a significant question regarding altered time perception in depression: Why do depressed people overproduce short durations and under-produce longer durations if their present experience is that time flows slowly? Experience and judgement of time do not seem to accord with one another. Analysis: By excluding two of the six studies on methodological grounds from a previous meta-analysis of medium-length interval productions, and re-analysing the remaining four studies, the present paper finds that subjective time accelerates from initial dilation within present experience (approximately 1 s duration) to subsequent acceleration within working memory (approximately 30 s duration) when depressed. Proposals: It is proposed that depressive time dilation and acceleration refer to the default mode and central executive networks, respectively. The acceleration effect is suggested to occur due to mood congruency between long intervals, boredom, and depression. This mood congruency leads to the automatic recall of intrusive, negative, and non-specific autobiographical long-term memories used to judge intervals from previous experience. Acceleration in working memory then occurs according to the contextual change model of duration estimation. Limitations: The meta-analysis is limited to four studies only, but provides a potential link between time experience and judgement within the same explanatory model. Conclusions: Similarities between psychological time dilation/acceleration and physical time dilation/acceleration are discussed.

  • Description: Background: 'How much change in training load is too much before injury is sustained, among different athletes?' is a key question in sports medicine and sports science. To address this question the investigator/practitioner must analyse exposure variables that change over time, such as change in training load. Very few studies have included time-varying exposures (eg, training load) and time-varying effect-measure modifiers (eg, previous injury, biomechanics, sleep/stress) when studying sports injury aetiology. Aim: To discuss advanced statistical methods suitable for the complex analysis of time-varying exposures such as changes in training load and injury-related outcomes. Content: Time-varying exposures and time-varying effect-measure modifiers can be used in time-to-event models to investigate sport injury aetiology. We address four key-questions (i) Does time-to-event modelling allow change in training load to be included as a time-varying exposure for sport injury development? (ii) Why is time-to-event analysis superior to other analytical concepts when analysing training-load related data that changes status over time? (iii) How can researchers include change in training load in a time-to-event analysis? and, (iv) Are researchers able to include other time-varying variables into time-to-event analyses? We emphasise that cleaning datasets, setting up the data, performing analyses with time-varying variables and interpreting the results is time-consuming, and requires dedication. It may need you to ask for assistance from methodological peers as the analytical approaches presented this paper require specialist knowledge and well-honed statistical skills. Conclusion: To increase knowledge about the association between changes in training load and injury, we encourage sports injury researchers to collaborate with statisticians and/or methodological epidemiologists to carefully consider applying time-to-event models to prospective sports injury data. This will ensure appropriate interpretation of time-to-event data. © 2019 Author(s).

  • Description: Background: Time-to-event modelling is underutilised in sports injury research. Still, sports injury researchers have been encouraged to consider time-to-event analyses as a powerful alternative to other statistical methods. Therefore, it is important to shed light on statistical approaches suitable for analysing training load related key-questions within the sports injury domain. Content: In the present article, we illuminate: (i) the possibilities of including time-varying outcomes in time-to-event analyses, (ii) how to deal with a situation where different types of sports injuries are included in the analyses (ie, competing risks), and (iii) how to deal with the situation where multiple subsequent injuries occur in the same athlete. Conclusion: Time-to-event analyses can handle time-varying outcomes, competing risk and multiple subsequent injuries. Although powerful, time-to-event has important requirements: researchers are encouraged to carefully consider prior to any data collection that five injuries per exposure state or transition is needed to avoid conducting statistical analyses on time-to-event data leading to biased results. This requirement becomes particularly difficult to accommodate when a stratified analysis is required as the number of variables increases exponentially for each additional strata included. In future sports injury research, we need stratified analyses if the target of our research is to respond to the question: 'how much change in training load is too much before injury is sustained, among athletes with different characteristics?' Responding to this question using multiple time-varying exposures (and outcomes) requires millions of injuries. This should not be a barrier for future research, but collaborations across borders to collecting the amount of data needed seems to be an important step forward.

  • Description: Plant strategy schemes aim to classify plants according to measurable traits and group species according to their shared evolutionary responses to selective pressures. In this way, it becomes possible to make meaningful comparisons among ecosystems and communities and to predict how plant communities might respond to changes in their environment. Here, we classified common alpine plants which occur in snowpatches (Early and Late snowmelt sites) and in adjacent vegetation (Snow-free sites which melt early in the growing season) using Grime's CSR plant strategy scheme. Alpine plant communities are largely driven by environmental filters associated with a relatively constant gradient of snowmelt timing. Since snow persistence influences the abiotic environment and plant assemblages alike, we hypothesised that these patterns would be reflected in community CSR scores. Weighted community CSR scores were clustered towards the stress-tolerator (S) corner of the triangular CSR space, and Snow-free communities were significantly more stress-tolerant than Early and Late snowmelt communities. This suggests that snowpatch communities are functionally distinct from surrounding vegetation when considering the major axes of plant variation identified by CSR theory. These results lend further support to the importance of the timing of snowmelt as a key filter, influencing how species and plant strategy types distribute themselves across the alpine landscape.

This approach is based on the extension of the classical de la Vallee-Poussin procedure originally developed for polynomial approximation.

  • Description: Nephrons scar and involute during aging, increasing the risk of chronic kidney disease. Little is known, however, about genetic mechanisms of kidney aging. We sought to define the signatures of age on the renal transcriptome using 563 human kidneys. The initial discovery analysis of 260 kidney transcriptomes from the TRANScriptome of renaL humAn TissuE Study (TRANSLATE) and the Cancer Genome Atlas identified 37 age-associated genes. For 19 of those genes, the association with age was replicated in 303 kidney transcriptomes from the Nephroseq resource. Surveying 42 nonrenal tissues from the Genotype–Tissue Expression project revealed that, for approximately a fifth of the replicated genes, the association with age was kidney-specific. Seventy-three percent of the replicated genes were associated with functional or histological parameters of age-related decline in kidney health, including glomerular filtration rate, glomerulosclerosis, interstitial fibrosis, tubular atrophy, and arterial narrowing. Common genetic variants in four of the age-related genes, namely LYG1, PPP1R3C, LTF and TSPYL5, correlated with the trajectory of age-related changes in their renal expression. Integrative analysis of genomic, epigenomic, and transcriptomic information revealed that the observed age-related decline in renal TSPYL5 expression was determined both genetically and epigenetically. Thus, this study revealed robust molecular signatures of the aging kidney and new regulatory mechanisms of age-related change in the kidney transcriptome.

  • Description: Purpose: The purpose of this paper is to explore how university fieldtrips progressively deepen student engagement, and explain that stage-by-stage using the organismic integration theory. Design/methodology/approach: Using reflective logs, follow-up focus groups after two years and facilitator observations, this Malaysian qualitative study followed 12 business students across two three-day rainforest fieldtrips. Findings: Students progressed toward greater – and enduring – engagement, and transferable socio-cognitive skills, via three thematic stages. Voice and self-reflection – motivated by protecting group harmony – were key, enabled by facilitator and peer encouragement. Research limitations/implications: This exploratory study invites research in specified education cultures. Further, a longitudinal, quantitative study could be designed to examine the conceptual framework developed in Figure 1. Practical implications: University curricula, especially in collectivist high power distance cultures, should include fieldtrips as a particularly powerful form of experiential learning. Benefits of deeper engagement extend beyond present to future courses and the workplace. Higher student attraction/retention and employability may follow. Intrinsic motivation grows through the student–instructor interaction, watching theoretical principles in action, and having eureka moments through reflection, expression and exchange of ideas. Originality/value: The research fills a gap by mapping student engagement progressively from extrinsic to intrinsic motivation along with socio-cognitive competencies. The authors reveal the centrality of voice and reflection to promote group harmony, explain the roles of facilitators and peers and show long-lasting transferable benefits to learning. Novelly, the authors provide empirical support for existing conceptual frameworks but also extend these.

  • Description: Online dating continues to grow in popularity and is associated with significant advantages; however, experiencing antisocial behaviours when online dating is a distinct possibility. The aim of the current study was to explore the utility of gender and the dark personality traits of narcissism, Machiavellianism, psychopathy, and sadism in predicting perpetration of a range of antisocial behaviours on the popular dating app Tinder. It was hypothesised that the male gender and higher scores on these personality traits would predict perpetration of antisocial behaviours on Tinder. Participants (N = 587; 21% men, 79% women) completed an online questionnaire, including the Antisocial Uses of Tinder® Scale which was constructed to measure a range of antisocial behaviours. Exploratory and Confirmatory factor analyses revealed three forms of antisocial behaviours (General, esteem, and sexual) which explained over half of the variance (58.99%) of variance in the Antisocial Uses of Tinder® measure. Regression analyses were run for each form of antisocial behaviour, and the predictive utility of gender and the dark traits were found to differ across the antisocial behaviours. Results of the current study support an individual differences approach to exploring antisocial behaviours online, particularly when online dating.

Fifty-eight participants (41 females; age 46 ± 11 yrs) of the “Start-to-Run” program provided self-reports on their RRIs using an online questionnaire. Subsequently, they attended injury consultations with sports medicine physicians who provided physician-reports (blinded for the self-reports) as a reference standard. Self-reports and physician-reports included information on injury location (i.e., hip/groin, upper leg, knee, lower leg, and ankle/foot) and injury type (i.e., muscle-tendon unit, joint, ligament, or bone). Sensitivity, specificity, and positive predictive values were 100% for all five injury locations. For injury type, sensitivity was low (66% for muscle-tendon unit, 50% for ligament, and 40% for bone) and lowest for joint injuries (17%). In conclusion, the validity of self-reported RRIs by novice runners is good for injury locations but not for injury types. In particular for joint injuries, the validity of novice runners’ self-reports is low.

  • Description: Quality of Life (QOL) has started to emerge as an important component across numerous disciplines including tourism. Whilst studies regarding QOL have been around for decades in many disciplines, the field is relatively new in tourism. The relationship between QOL and tourism is important given that there have been studies revealing that travel can increase an individual's perceived and actual QOL. Those studies that have examined the relationship between QOL and tourism have focused on pleasure/leisure travel. Thus, other types of travel, namely Visiting Friends and Relatives (VFR) travel have not been examined with respect to QOL. In terms of QOL, VFR can be derided in conversation, identifying it as an unwanted irritation that can hardly boost QOL. This is particularly relevant in terms of VFR hosting. However, the link between VFR and QOL has not been empirically tested and as such, it is unclear whether VFR can improve or reduce QOL. Accordingly, this paper examines the link between VFR travel and QOL. Based on a sample size of 552 across Australia, this research found that whilst VFR can reduce QOL in some situations, in most cases, positive QOL benefits arise from both hosting and visiting VFRs. © 2019
