A larger, stronger deployable boom was developed to handle the requirements of larger, heavier payloads in space. The main components of the boom and its deployer are described and their functions explained. Desirable features of the boom are identified and physical properties are reported

Relatchable launch restraint mechanism for deployable booms

A new Relatchable Launch Mechanism was developed which enables a deployable system to be restrained and released repeatedly rather than the normal one shot release systems of the past. The deployable systems are of the self extending type which rely on a lanyard attached to a drive motor to control the deployment and retraction. The Relatch Mechanism uses the existing drive motor to also actuate the latch. The design and kinematics of the Relatch Mechanism as used on two flight programs are described

Throwing enhances humeral shaft cortical bone properties in pre-pubertal baseball players: a 12-month longitudinal pilot study

Objectives: To explore throwing athletes as a prospective, within-subject controlled model for studying the response of the skeleton to exercise. Methods: Male pre-pubertal throwing athletes (n=12; age=10.3±0.6 yrs) had distal humerus cortical volumetric bone mineral density (Ct.vBMD), cortical bone mineral content (Ct.BMC), total area (Tt.Ar), cortical area (Ct.Ar), medullary area (Me.Ar), cortical thickness (Ct.Th) and polar moment of inertia (IP) assessed within their throwing (exercised) and nonthrowing (control) arms by peripheral quantitative computed tomography at baseline and 12 months. Throwing-to-nonthrowing arm percent differences (i.e. bilateral asymmetry) were compared over time. Results: Over 12 months, the throwing arm gained 4.3% (95% Cl=1.1% to 7.5%), 2.9% (95% Cl=0.3% to 5.4%), 3.9% (95% Cl=0.7% to 7.0%), and 8.2% (95% Cl=2.0% to 6.8%) more Ct.BMC, Ct.Ar, Tt.Ar, and IP than the nonthrowing arm, respectively (all p<0.05). There was no significant effect of throwing on Ct.vBMD, Ct.Th and Me.Ar (all p=0.18-0.82). Conclusion: Throwing induced surface-specific cortical bone adaptation at the distal humeral diaphysis that contributed to a gain in estimated strength. These longitudinal pilot data support the utility of throwing athletes as a within-subject controlled model to explore factors influencing exercise-induced bone adaptation during the critical growing years

Absence of age effects on spontaneous past and future thinking in daily life

© Springer-Verlag GmbH Germany, part of Springer Nature 2018.Previous research on voluntary mental time travel (i.e., deliberately thinking about the past or future) has resulted in negative age effects. In contrast, studies on spontaneous past thoughts (i.e., involuntary autobiographical memories) have reported small or no age effects. The aim of the present research was to investigate the effects of age on the nature and frequency of spontaneous future thoughts in everyday life. In two studies, we examined whether older adults reported spontaneous future thoughts as often as younger adults, and whether these thoughts were predominantly goal-oriented and less dependent on incidental cues than thoughts about the past. In Study 1, young and old participants kept a diary of spontaneous thoughts of upcoming prospective memory tasks and involuntary autobiographical memories for 2 weeks. In Study 2, a 1-day experience sampling method was used to investigate spontaneous and deliberate task-unrelated future and past thoughts, by having young and old participants complete a questionnaire in response to 30 random signals. In both studies, no age effects were found in the frequency of spontaneous future thoughts, which were reported as frequently as thoughts about the past (Study 2) and referred predominantly to upcoming tasks and goals rather than future events or hypothetical events (Study 2). Results concerning the triggers of reported thoughts provide initial support for the idea that representations of future thoughts may be more activated than memories of past events. Taken together, these results have important implications for research on cognitive ageing, mind-wandering, prospective memory and involuntary autobiographical memories.Peer reviewedFinal Accepted Versio

Emotion and coping in young victims of peer-agression

Peer-aggression and peer-victimization have been the subject of considerable research interest over the past quarter century. There has been a focus on perpetrators of violence and aggression, based upon the belief that clarification of group and individual processes underpinning aggression will lead to effective intervention and prevention strategies. However, while it is unrealistic to hope that we can completely eradicate aggression, only by clarifying why children and young people respond in certain ways when confronted by peer-aggression can we effectively and efficiently help them to help themselves. In this way, young people can be taught resilience and practical coping skills which will help them to deal with peer-aggression when it occurs, and they can also be helped to more effectively manage emotional reactions when involved in ongoing peer-victimization. Transactional coping theory (Lazarus, 1999) provides an excellent framework for clarifying the important pathways leading to individual differences in emotional reactions and the use of coping strategies by children and young people. In the present chapter, we review the research with victims of peer-aggression which has touched on these questions, and follow this with review of relevant studies from the stress and coping literature which shed light on the relationships between appraisals, emotions and coping strategies. We also report results from a study of our own examining these variables in a sample of children and adolescents experiencing peer-aggression, and draw conclusions for theory and practice based upon these

Sustainable social (enterprise) entrepreneurship. An organisational and individual identity perspective.

Purpose - to investigate the phenomenon of sustainable social (enterprise) entrepreneurship from both organisational and individual/personal identity perspectives. Two research questions ask: (RQ1) what are the key organisational identity (OI) and governance issues associated with sustainable social enterprises (SEs) and social entrepreneurship?, and; (RQ2) who are the social enterprise (SE) leaders/entrepreneurs (and why are they important from an identity perspective)? Design/methodology/approach – A stage 1 interpretative phenomenological analysis (IPA) employed 30 semi-structured interviews of social entrepreneurs in the (UK) South East; a macro-level conceptualisation of social enterprise (organisational) identity, sustainability and governance issues being the key deliverable. This was followed by a stage 2 social constructionist and social entrepreneurial identity study; whereby, 16 in-depth interviews, with 3 case study social enterprise leaders were conducted over a period of three years. Stage 3 involved 2 employee and volunteer focus groups to help triangulate data from the previous stages. Finally, stage 4 follow-up interviews with 4 selected informants helped evaluate the impact of the Brexit vote on my thesis arguments. Various third sector and government policy documents were consulted throughout the study. Findings – Firstly, I argue that understanding who organisations are, as well as, what they do, are important for understanding the sustainability of social enterprises, and the third sector. A new conceptual social enterprise grid (SEG) is developed to distinguish who social enterprises are; relative to other third and public-sector organisations. Secondly, a Ricoeurian narrative analysis helps demonstrate the agentic role of social entrepreneurs; how social enterprise sustainability is motivated by personal beliefs, social values and an idem (i.e. almost permanent) sense of identity. Similarly, results demonstrate how social enterprise sustainability could be at least part-attributed, to the lifetime agentic function of social entrepreneurs. Originality/value – This PhD thesis addresses fundamental definitional and theory gaps in the social enterprise and third sector identity literatures. It contributes by offering fresh perspectives on the complex and inter-related issues of (organisational and socio-entrepreneurial) identity, governance and sustainability

Prosocial and antisocial children's perceptions of peers' motives for prosocial behaviours

This study investigated whether peer-nominated prosocial and antisocial children have different perceptions of the motives underlying peers' prosocial actions. Eighty-seven children, aged 10-12 years old, completed peer-nomination measures of social behaviour. On the basis of numbers of social nominations received, a subsample of 51 children (32 who were peer-nominated as 'prosocial', and 18 who were peer-nominated as 'antisocial') then recorded their perceptions of peers' motives for prosocial behaviours. Expressed motives were categorized predominantly into three categories, coinciding with Turiel's (1978) 'moral', 'conventional', and 'personal domains'. Results indicate that children's social reputation is associated with the extent to which they perceive peers' prosocial motives as 'personal' or 'moral', with more prosocial children attributing moral motives, and more antisocial children attributing personal motives. Although traditionally Turiel's domain theory has been used to understand 'antisocial' children's behaviour, the current findings suggest that 'prosocial' children's behaviour may also be related to domains of judgment

Perceptions and correlates of peer-victimization and bullying

The experiences of peer-victimization and bullying are often treated empirically as though they are conceptually indistinct. Both involve repeated aggression,but definitions of bullying additionally emphasize the importance of aggressor intent and imbalance of power between the aggressor and the victim (Olweus, 1978; Whitney & Smith, 1993). The present study aimed to examine the extent to which peer-victimization and bullying are empirically similar. The sample comprised 1,429 pupils (50.2% male) aged between 8 and 13 years attending mainstream Scottish schools. Self-report questionnaire assessing peer-victimization and bullying, copingstrategy use (WCCL: Hunter, 2000), situational appraisal and depressive symptomatology (Birleson, 1981). Almost one-third (30.7%) of pupils reported experiencing peer-victimization, and of these 38.1% (11.7% of whole sample) were categorized as victims of bullying. Victims of bullying perceived higher levels of threat and lower levels of perceived control. They also reported using more Wishful Thinking and Social Support coping strategies, but did not differ on Problem Focused coping. Bullied pupils also reported higher levels of depressive symptomatology. Peer-victimization and bullying appear to be qualitatively different experiences for children and adolescents, with bullying being the more serious phenomenon
