Aerospace Medicine - Abstract
Neurolab is a NASA Spacelab mission with multinational cooperative participation that is dedicated to research on the nervous system. The nervous systems of all animal species have evolved in a one-g environment and are functionally influenced by the presence of gravity. The absence of gravity presents a unique opportunity to gain new insights into basic neurologic functions as well as an enhanced understanding of physiological and behavioral responses mediated by the nervous system. The primary goal of Neurolab is to expand our understanding of how the nervous system develops, functions in, and adapts to microgravity space flight. Twenty-six peer reviewed investigations using human and nonhuman test subjects were assigned to one of eight science discipline teams. Individual and integrated experiments within these teams have been designed to collect a wide range of physiological and behavior data in flight as well as pre- and postflight. Information from these investigations will be applicable to enhancing the well being and performance of future long duration space travelers, will contribute to our understanding of normal and pathological functioning of the nervous system, and may be applied by the medical community to enhance the health of humans on Earth.

- Abstract
Analyses are presented of the anticipated earthquake performance of three generally similar earth dams, situated in a seismically active area of northern California. The series of analyses illustrates a cost-effective approach which involved full-scale finite element analyses of one dam, and the use of limited dynamic analysis techniques and correlations to evaluate the other two. The simplified techniques were applied only after testing them against the finite element analyses, information is also presented on how the results of simplified and full-scale dynamic analysis procedures correlate.

- Abstract
Stevens Creek Darn is a rolled earthfill structure with a height of about 120 feet. A seismic safety evaluation in 1978 concluded that the darn would probably be severely damaged if subjected to a maximum credible earthquake originating on the nearby San Andreas fault. Normal reservoir operation was immediately restricted, pending decisions as to the fate of the project. Conceptual design studies were completed in 1982 to identify the most promising alternative remedial concepts. The most promising concepts were chosen and final design of modifications to the dam and its appurtenant hydraulic structures were completed in 1984. Modification of the darn was completed in 1986, involving the placement of massive buttresses on both the upstream and downstream slopes and installation of internal drains to control the phreatic line. This required extension of the existing outlet conduit and construction of new inlet and outlet control structures.

- Abstract
Introduction: Behaviour change interventions are advocated as a key approach to manage behavioural risk factors such as insufficient physical activity, poor diet and smoking. Integrated motivational interviewing and cognitive behavioural therapy (MI-CBT) interventions have become increasingly popular to promote behaviour change; however, there is a lack of agreement as to what constitutes necessary components of MI-CBT interventions for lifestyle behaviour change. The primary objective of this study is to use a consensus method to develop guidelines to design and deliver MI-CBT interventions for lifestyle behaviour change., Methods: A three-round modified Delphi study will be conducted with an expert, international panel of clinicians and researchers. An online survey will be developed from assessments of key MI-CBT literature and practice guides to identify commonly used components of individually delivered MI and CBT interventions. In each round, participants will rate the extent to which they agree with each component using a Likert scale. Responses from Rounds 1 and 2 will be presented to participants in subsequent rounds. Responses will be represented using bar graphs and include the median and IQR of participants' responses. To encourage consensus, participants will be asked to consider the group responses before finalising their opinion to the statements. If at least 80% of the experts agree to a statement in Rounds 2 or 3, it will be included in a final list of necessary statements., Discussion: This modified Delphi process will help transparency in the design and implementation of MI-CBT interventions. The consensus statement will also help reporting and comparability among effectiveness studies for MI-CBT intervention studies, and help inform research, policy and practice., Ethics and Dissemination: Ethical approval has been granted by the La Trobe University Human Research Ethics Committee (approval number HEC24066). The results will be disseminated via peer-reviewed publications, conferences and international professional associations., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

- Abstract
Objective: Behaviour change interventions targeting changes in physical activity (PA) can benefit by examining the underlying mechanisms that promote change. This study explored the use of the Capability, Opportunity, Motivation and Behaviour (COM-B) model and the Theoretical Domains Framework (TDF) to code and contextualise the experiences of participants who completed a PA coaching intervention underpinned by motivational interviewing and cognitive-behavioural therapy., Design: Semistructured interviews were conducted with a purposive sample of participants., Setting: Interviews were conducted in a tertiary hospital in regional Victoria, Australia., Participants: Eighteen participants who completed a PA coaching intervention were interviewed. The participants were recruited into the coaching intervention because they were insufficiently physically active at the time of recruitment., Results: Thirteen (72%) participants were women and the average age of participants was 54 (±5) years. Four participant themes mapped directly onto five components of the COM-B model, and ten of the TDF domains. Increases in PA were influenced by changes in motivation and psychological capability. The autonomy-supportive PA coaching intervention helped to evoke participants' own reasons (and motives) for change and influenced PA behaviours. Participants reflected on their own social and/or professional strengths, and used these skills to set appropriate PA goals and action plans. The structure of the PA coaching intervention provided clarity on session determinants and a framework from which to set an appropriate agenda. Relational components (eg, non-judgemental listening, collaboration) were continually highlighted as influential for change, and should be considered in future behaviour change intervention design., Conclusions: We demonstrate the beneficial effect of using theory-informed behaviour change techniques, and delivering them in a style that promotes autonomy and relatedness. The views of participants should be a key consideration in the design and implementation of PA coaching interventions TRIAL REGISTRATION NUMBER: ACTRN12619000036112.

- Abstract
Background: Hospital clinicians are increasingly encouraged to use outpatient consultations as an avenue to deliver opportunistic health promotion. There is a dearth of evidence regarding the acceptance of health promotion initiatives from hospital patients themselves., Methods: We explored the experiences of non-admitted patients who, during a routine consultation with a hospital surgeon received a recommendation to increase physical activity (PA) and a recommendation to engage in a PA telephone coaching program. Twenty-two semi-structured interviews were conducted with individuals who had received the recommendation and proceeded to enroll in a telephone coaching intervention to identify factors that influenced behavior change. Data were analyzed thematically., Results: Participants' age ranged between 42 and 66 years, with the average age being 54 years. Of the participants, 15 (68%) were women and 7 (32%) were men. Three major themes were identified: (1) the hospital visit represented an opportunity for behavior change that is not to be missed; (2) surgeons were influential in promoting PA change contemplation; and (3) patients welcomed a communication style that promoted autonomy., Conclusions: Almost all patients considered receiving the recommendation to engage with the telephone coaching as acceptable and helpful toward PA change. Although working in time-restricted consultations, surgeons delivered the recommendation in a patient-centered, autonomy-supportive way, which influenced behavior change. Hospitals should explore avenues to integrate health promotion into routine care, confident of the acceptability and appropriateness of health promotion practice to hospital patients., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Barrett, Begg, O'Halloran, Rodda, Barrett and Kingsley.)

- Abstract
Objective: This paper explores the experiences of individuals who reported substantially decreasing physical activity (PA) as a result of COVID-19 and sought coaching support to increase PA., Methods: A qualitative study using phenomenological analysis. Eight individuals participated in semi-structured interviews that focused on their experiences of decreasing PA as a result of physical distancing measures, and why they sought PA coaching to overcome these issues. Responses were analysed thematically., Results: The participants reported markedly decreasing their PA following the enactment of physical distancing measures. The inability to subsequently engage in regular PA was a source of frustration for participants. Interview analysis revealed two themes that contributed to the understanding of why these individuals felt they needed PA coaching to increase PA; namely, a desire for both listening support and PA self-regulation support., Conclusion: The individuals who decreased PA due to COVID-19 desired an autonomy-supportive counselling style, centred on listening support and self-regulatory support. Online PA interventions were not highlighted as strategies to overcome PA barriers. Implications for public health: The effect of physical distancing measures on the determinants of overall PA is important, particularly if prolonged physical distancing is required., (© 2021 The Authors.)
