Parent-Child Interactions May Help to Explain Relations Between Parent Characteristics and Clinically Observed Child Autistic Behaviours
No full textThe importance of supporting parent-child interactions has been noted in the context of prodromal autism, but little consideration has been given to the possible contributing role of parental characteristics, such as psychological distress. This cross-sectional study tested models in which parent-child interaction variables mediated relations between parent characteristics and child autistic behaviour in a sample of families whose infant demonstrated early signs of autism (N = 103). The findings suggest that associations between parent characteristics (psychological distress; aloofness) and child autistic behaviours may be mediated by the child’s inattentiveness or negative affect during interactions. These findings have important implications in developing and implementing interventions in infancy which target the synchrony of parent-child interaction with the goal to support children’s social communication development
LGBTQ Mental Health Peer Support: A Descriptive Survey
No full textAbstract: Background Gender and sexual minority adults have significant unmet mental health care needs and are often faced with barriers to accessing appropriate services. In this context, LGBTQ individuals often turn to each other for mental health support. Methods: In a sample of 326 LGBTQ adults (M age = 37.64) who were providing mental health support to their LGBTQ peers, we examined the nature of LGBTQ peer support, including who provides peer support, to whom, and for what issues. We also examined the experiences of those providing LGBTQ peer support, and the role of mental health training. Data were collected in 2020. Results: Participants provided support to a range of individuals, including close friends, colleagues, and those who were previously strangers. The types of concerns they supported their peers with varied greatly, though depression, anxiety, suicidality, and coping with discrimination were common concerns. Participants were often managing multiple competing demands, and many appeared to be managing their own mental health concerns. Those who had received at least some mental health training appeared to fare better in their experiences of providing peer support compared to those without such training. Policy Implications: Findings illustrate the importance of increasing access to LGBTQ-affirmative mental health services. We also highlight the importance of developing and disseminating initiatives designed to support those providing LGBTQ peer support, both to increase the effectiveness of peer support and to help manage the impact of providing LGBTQ peer support.</p
A framework for test measurement selection in athlete physical preparation
No full textPreparing athletes for competition requires the diagnosis and monitoring of relevant physical qualities (e.g., strength, power, speed, endurance characteristics). Decisions regarding test selection that attempt to measure these physical attributes are fundamental to the training process yet are complicated by the myriad of tests and measurements available. This article presents an evidenced based process to inform test measurement selection for the physical preparation of athletes. We describe a method for incorporating multiple layers of validity to link test measurement to competition outcome. This is followed by a framework by which to evaluate the suitability of test measurements based on contemporary validity theory that considers technical, decision-making, and organisational factors. Example applications of the framework are described to demonstrate its utility in different settings. The systems presented here will assist in distilling the range of measurements available into those most likely to have the greatest impact on competition performance
Modelling Role of Protective and Nonprotective HLA Allele Inducing Different HIV Infection Outcomes
No full textHuman immunodeficiency virus (HIV) infects CD4+ cells and causes progressive immune function failure, and CD8+ cells lyse infected CD4+ cell via recognising peptide presented by human leukocyte antigens (HLA). Variations in HLA allele lead to observed different HIV infection outcomes. Within-host HIV dynamics involves virus replication within infected cells and lysing of infected cells by CD8+ cells, but how variations in HLA alleles determine different infection outcomes was far from clear. Here, we used mathematical modelling and parameter inference with a new analysis of published virus inhibition assay data to estimate CD8+ cell lysing efficiency, and found that lysing efficiency fall in the gap between low bound (0.1–0.2 day−1 (Elemans et al. in PLoS Comput Biol 8(2):e1002381, 2012)) and upper boundary (6.5–8.4 day−1 (Wick et al. in J Virol 79(21):13579–13586, 2005)). Our outcomes indicate that both lysing efficiency and viral inoculum size jointly determine observed different infection outcomes. Low lysing rate associated with non-protective HLA alleles leads to monostable viral kinetic to high viral titre and oscillatory viral kinetics. High lysing rate associated with protective HLA alleles leads monostable viral kinetic to low viral titre and bistable viral kinetics; at a specific interval of CD8+ cell counts, small viral inoculum sizes are inhibited but not large viral inoculum sizes remain infectious. Further, with CD8+ cell recruitment, HIV kinetics always exhibit oscillatory kinetics, but lysing rate is negatively correlated with range of CD8+ cell count. Our finding highlights role of HLA allele determining different infection outcomes, thereby providing a potential mechanistic explanation for observed good and bad HIV infection outcomes induced by protective HLA allele
Utilising existing data for a pilot social return on investment analysis of the family wellbeing empowerment program: A justification and framework
No full textDemand is growing in the public, private, and philanthropic sectors for economic and quantifiable outcome data to guide decisions regarding the allocation of resources. This paper explores the challenges and opportunities in economically evaluating an Aboriginal Social and Emotional Wellbeing intervention, emphasising the value of utilising existing data. Driven by local and national Indigenous research priorities, the study involved a pilot Social Return on Investment analysis of the Aboriginal Family Wellbeing empowerment program. Underpinned by a collaborative mixed-methods approach, designed to mitigate data limitations and bolster trustworthiness, the analysis was undertaken across four stages, including a literature review to identify impacts and create a theory of change; co-design of an impacts framework; a targeted literature review to inform impact quantification and attribution; and calculation of the Social Return on Investment results. Results indicate that for every Australian dollar of investment in delivering Family Wellbeing between 2001 and 2021 in the Yarrabah Aboriginal community, A$4.60 of benefits were produced for participants and the community. The return is expected to be higher if important community and cultural impacts of the program were included in the monetisation. Data limitations and implications for future mixed methods economic evaluation of social interventions are explored
Ticket sales versus catering challenges for entrepreneurial hospitality workers at international events: A case study of the Melbourne International Comedy Festival (MICF)
No full textABSTRACT: Objective: The objective of the article is to examine the catering challenges for hospitality workers versus ticket sales at the Melbourne International Comedy Festival (MICF) in terms of their entrepreneurial behaviour. Research Design & Methods: This qualitative conceptual paper is based on interviewing hospitality workers at the MICF. Semi-structured interviews were used to survey venue managers and temporary hospitality workers whilst working at the MICF. Findings: The findings showcase that although some service processes at international comedy festivals can improve, it is unlikely to change in any significant way due to the nature of how comedy festivals are operated and for the duration for the individual shows. It is not feasible to have too many full-time staff or event part-time staff when a temporary or casual work force can service ticket holders even though some people may have a negative experience. Therefore, the workers need to develop entrepreneurial skills in order to succeed in the competitive marketplace. Implications & Recommendations: Investigating the challenges hospitality workers experience at the MICF when ticket sales are continually sold up until the performance is the first attempt at qualitative research in this field of study bridging the gap in event management, festival, and hospitality literature. It highlights the use of temporary hospitality workers as the main labour force of international comedy festivals and showcases some of the challenges hospitality workers experience. It acknowledges the need to think outside the box and to be innovative with work decisions. Contribution & Value Added: This paper adds to the growing body of literature in challenges for the hospitality industry, temporary hospitality workers, international comedy events and last-minute ticket sales and offers practical implications to assist in future large-scale comedy and fringe festivals for the first time.</p
Will my shoulder pain get better? – secondary analysis of data from a multi-arm randomised controlled trial
No full textObjective: To determine whether higher level or improvements over time in pain self-efficacy (PSE) and expectations of intervention effectiveness lead to better outcomes and whether the intervention used to manage rotator cuff related shoulder pain (RCRSP) impacts PSE and expectations over time. Design: Secondary analysis of data from a randomised controlled trial. Participants: 123 individuals (48 [15] years old; 51% female) with RCRSP. Interventions: Participants randomised into one of three 12-weeks interventions (education; education and motor control exercises; education and strengthening exercises). Main outcome measures: QuickDASH and Western Ontario Rotator Cuff Index (WORC) were administered at baseline and 12 weeks. Pain self-efficacy was assessed at 0 and 6 weeks. Patients’ expectations regarding intervention effectiveness were assessed before randomisation and after the first and the last intervention sessions. NparLD were used for the analyses. A time effect indicated a significant change in patients’ expectations or PSE over time, while a resolution effect indicated a significant difference in patients’ expectations or PSE between those whose symptoms resolved and those whose did not. Results: Patients’ expectations (−3 to 3) increased over time (0.33/3 [0.19 to 0.77]). Overall expectations were higher for those who experienced symptom resolution based on the WORC (0.19/3 [0.05 to 0.33]). PSE increased over time (5.5/60 [3.6 to 7.4]). Overall PSE was higher for those who experienced symptom resolution based on the WORC (7.0 [3.9 to 10.1]) and the QuickDASH (4.9 [1.7 to 8.2]). Conclusion: Clinicians should consider monitoring PSE and patients’ expectations as they are important indicators of outcome. </p
Sex on screens: the language of sexting and amateur pornography
No full textFrequently referred to as ‘sexting’ or ‘amateur pornography’, digital sexual images and videos form an increasingly common part of adult sexual relationships. However, the vocabulary available to speak about these practices is limited, with ‘sexting’ often associated with young people in negative terms. This study is based on 23 interviews with adults in Australia who are 25 years and older. It explores the language adults employ to discuss and comprehend the creation and sharing of sexualised images and videos. Findings show that negative or positive connotations associated with the terms used to discuss sexual images and videos influenced the ways participants drew on, or rejected, terms to align digital practices with their sexual subjectivity. Reticence to engage in active communication about digital sexual practices, and participant’s distancing of their own practices from the terms commonly understood to refer to such practices, made it difficult to engage in conversations about consent or desire in the context of digitally mediated sex. Findings provide insight into the ways that digital sexual subjectivities are discursively framed and extend these implications for sexual health promotion with respect to how to frame messages of digital sexual safety in a sex-positive and open way
Extended-range luminescence and ESR dating of Iberian fluvial terraces (Duero and Guadiana basins) associated with the Lower Palaeolithic sites of La Maya I, II, III, Burganes and Albalá (west-central Spain)
No full textThe major river basins of the Iberian Peninsula that drain towards the Atlantic coast contain extensive Lower Palaeolithic (Acheulean) records associated with well-preserved fluvial terrace sequences. These open-air archaeological records are often difficult to constrain chronologically due to a lack of suitable material for dating (e.g., faunal remains) or because their Middle Pleistocene antiquity precludes the use of otherwise routinely applicable geochronometric techniques such as conventional optically stimulated luminescence (OSL) dating. As a result, many important Iberian Acheulean sites lack precise and accurate chronologies, and their existing temporal frameworks are based solely on morphostratigraphic correlations with regional fluvial terrace systems. Here we present the first application of extended-range luminescence dating – namely multi-grain post-infrared infrared stimulated luminescence (pIR-IRSL) dating of K-feldspars and single-grain thermally transferred-OSL (TT-OSL) dating of quartz – to a series of terrace sequences in the Duero basin (central sector) and Guadiana basin, as well as associated Lower Palaeolithic sites of La Maya I, II and III along the Tormes River, Burganes (and related sites) along the Tera River, and Albalá along the Guadiana River. Additionally, we present results of a parallel electron spin resonance (ESR) quartz dating study of the Tormes River terrace (Duero basin), which has been undertaken independently on the same samples to enable stratigraphically paired dating comparisons. Our study indicates that sedimentary quartz from this sector of the Duero basin produces very weak TT-OSL signals, variable Al signal repeatability and below-average Ti signal fitting uncertainties, though it is still possible to determine consistent comparative ages using the measurements protocols employed here. For samples where both pIR-IRSL and TT-OSL signals were measured, the paired luminescence dating ages are in agreement at 1σ. Agreement between the quartz ESR and TT-OSL ages is also observed for one sample from the Tormes River. However, the ESR signals (both Al and Ti) of a second sample showed insufficient bleaching and age overestimation in comparison to the paired TT-OSL dataset. Comparison of our latest dating results with published chronological datasets point to some fluvial terraces of the Duero basin potentially having diachronous formation histories. Despite this, our combined chronological results show that the terrace systems are chronologically ordered and suggest that, regionally, the +8 to +34 m terraces likely post-date marine isotope stage (MIS) 10, whilst the +50 m terraces formed prior to, or during, MIS 10. The related Acheulean sites that contain lithic material in stratigraphic position are dated to MIS 9–7 (193–314 ka at 2σ age range), and temporally overlap with the early Middle Palaeolithic records in the Duero basin, also dated here to MIS 8–7 (or 159–259 ka at 2σ). Our results are consistent with previous observations regarding the chronological overlap of these two technologies in the region, and support the possibility of a non-linear pattern of replacement for the Acheulean in the Iberian Peninsula during the Lower to Middle Palaeolithic transition
