Astronaut Adherence to Exercise-Based Reconditioning:Psychological Considerations and Future Directions
IntroductionExercise-based reconditioning is essential for mitigating the negative physiological and functional effects of spaceflight. Astronaut adherence to prescribed reconditioning programmes is imperative, but there has been limited research in this area.PurposeThis commentary discusses adherence predictors in analogous terrestrial populations (sport, clinical rehabilitation, general exercise) that may translate to spaceflight environments.ImplicationsReconditioning programmes should foster intrinsic motivation, realistic outcome expectancies, self-regulation skills, and strong therapeutic alliances to promote ongoing exercise adherence. Research is needed to understand spaceflight-specific barriers and facilitators to adherence, and to develop appropriate strategies to promote ongoing exercise behaviours
Predicting exercise motivation and exercise behavior: A moderated mediation model testing the interaction between perceived exercise variety and basic psychological needs satisfaction
ObjectivesPerceived variety in exercise predicts exercise behavior through autonomous motivation. However, psychological need satisfaction (viz. for competence, autonomy, and relatedness) may moderate the relationship between perceived variety in exercise and exercise behavior (through autonomous motivation). The purpose of the present study was to examine whether the satisfaction of the basic psychological needs in exercise contexts moderates the mediating role of autonomous exercise motivation in the relationship between perceived variety in exercise and exercise behavior.DesignCross-sectional.MethodAdults (N = 499) completed an online questionnaire to measure the study variables. Associations were examined using structural equation modeling.ResultsPsychological need satisfaction moderated the positive indirect relationship between perceived exercise variety and self-reported exercise behavior (via autonomous motivation) such that perceived variety was associated with exercise behavior when psychological need satisfaction scores were lower than average.ConclusionsBased on these findings, perceived exercise variety may act as a compensatory source of motivation when psychological need satisfaction is low. In addition to attempting to foster need-supportive exercise contexts, it may be particularly important for exercise promotion specialists to foster the experience of variety among individuals who have lower psychological need satisfaction

Comparison of Electron-Atom Collision Parameters for S to P Transitions under Reversal of Energy Transfer
Inelastic and superelastic electron scattering from the optically prepared 32P3/2 state of sodium has enabled atomic collision parameters to be deduced for the 4S-3P deexcitation and the 3S-3P excitation processes. These data are compared with convergent close coupling and second order distorted wave Born calculations. For excitation, both theories agree with experiment, whereas for deexcitation the close coupling theory is in better agreement. A long-standing proposal relating to the sign of the transferred angular momentum is not supported

Care homes’ use of medicines study: prevalence, causes and potential harm of medication errors in care homes for older people
Introduction: Care home residents are at particular risk from medication errors, and our objective was to determine the prevalence and potential harm of prescribing, monitoring, dispensing and administration errors in UK care homes, and to identify their causes.
Methods: A prospective study of a random sample of residents within a purposive sample of homes in three areas. Errors were identified by patient interview, note review, observation of practice and examination of dispensed items. Causes were understood by observation and from theoretically framed interviews with home staff, doctors and pharmacists. Potential harm from errors was assessed by expert judgement.
Results: The 256 residents recruited in 55 homes were taking a mean of 8.0 medicines. One hundred and seventy-eight (69.5%) of residents had one or more errors. The mean number per resident was 1.9 errors. The mean potential harm from prescribing, monitoring, administration and dispensing errors was 2.6, 3.7, 2.1 and 2.0 (0 = no harm, 10 = death), respectively. Contributing factors from the 89 interviews included doctors who were not accessible, did not know the residents and lacked information in homes when prescribing; home staff’s high workload, lack of medicines training and drug round interruptions; lack of team work among home, practice and pharmacy; inefficient ordering systems; inaccurate medicine records and prevalence of verbal communication; and difficult to fill (and check) medication administration systems.
Conclusions: That two thirds of residents were exposed to one or more medication errors is of concern. The will to improve exists, but there is a lack of overall responsibility. Action is required from all concerned
Autonomy support, basic need satisfaction and the optimal functioning of adult male and female sport participants: A test of basic needs theory
Grounded in Basic Needs Theory (BNT; Ryan and Deci, American Psychologist, 55, 68–78, 2000a), the present study aimed to: (a) test a theoretically-based model of coach autonomy support, motivational processes and well-/ill being among a sample of adult sport participants, (b) discern which basic psychological need(s) mediate the link between autonomy support and well-/ill-being, and (c) explore gender invariance in the hypothesized model. Five hundred and thirty nine participants (Male = 271;Female = 268; Mage = 22.75) completed a multi-section questionnaire tapping the targeted variables. Structural Equation Modeling (SEM) analysis revealed that coach autonomy support predicted participants’ basic need satisfaction for autonomy, competence and relatedness. In turn, basic need satisfaction predicted greater subjective vitality when engaged in sport. Participants with low levels of autonomy were more susceptible to feeling emotionally and physically exhausted from their sport investment. Autonomy and competence partially mediated the path from autonomy support to subjective vitality. Lastly, the results supported partial invariance of the model with respect to gender
Economic Backwardness and Social Tension
We propose that relative economic backwardness contributes to the build-up of social tension and non-violent and violent conflict. We test our hypothesis using data on organized mass movements and armed civil conflict. The findings show that greater economic backwardness is consistently linked to a higher probability of onset of violent and especially non-violent forms of civil unrest. We provide evidence that the relationship is causal in instrumental variables estimations using new instruments, including mailing speeds and telegram charges around 1900. The magnitude of the effect of backwardness on social tension increases in the two-stage least-squares estimations
Getting Published: Suggestions and Strategies from Editors of Sport and Exercise Psychology Journals
Publishing in peer review journals is an acquired skill that almost any scholar–practitioner can achieve through a systematic approach and practice. The authors of this manuscript are experienced editors from five leading international sport and exercise psychology peer-review journals. Within this manuscript, the contributing authors considered how one could effectively proceed in the authoring process from the point of conceptualization onward to manuscript acceptance. Particular focus has been placed on journal requirements, useful content suggestions in relation to all components of a manuscript, and the revision process. A final summation is provided with key takeaway points. The intention is to further author understanding and effective authoring pathways in relation to academic publishing in any sport and exercise psychology-focused journal
