Behavior change is more effective and lasting when patients are autonomously motivated. To examine this idea, we identified 184 independent data sets from studies that utilized self-determination theory (SDT; Deci & Ryan, 2000) in health care and health promotion contexts. A meta-analysis evaluated relations between the SDT-based constructs of practitioner support for patient autonomy and patients' experience of psychological need satisfaction, as well as relations between these SDT constructs and indices of mental and physical health. Results showed the expected relations among the SDT variables, as well as positive relations of psychological need satisfaction and autonomous motivation to beneficial health outcomes. Several variables (e.g., participants' age, study design) were tested as potential moderators when effect sizes were heterogeneous. Finally, we used path analyses of the meta-analyzed correlations to test the interrelations among the SDT variables. Results suggested that SDT is a viable conceptual framework to study antecedents and outcomes of motivation for health-related behaviors.

Theories of mindfulness claim that a state of present-moment awareness enhances self-regulation in the presence of negative emotion. However, very little research has tested this claim in relation to daily stressors. This paper examined whether present-moment awareness during daily stressful events predicted enhanced responding to (a) the same day’s event, (b) a stressful event on the subsequent day and (c) stressful events on average, among a sample of adults (N=143) over 20days. We found support for these predictions, controlling for negative affect and stress-related appraisals. These novel findings extend the personality literature by showing that present-moment awareness facilitates adaptive stress-responses, independent of an individual’s affective state and the severity of threat experienced.

Au vu des recherches portant sur les classes de mots, on constate que le domaine de l’adjectif est, avec celui de l’adverbe, relativement peu investi, meme s’il attire, notamment depuis la fin du siecle dernier, de plus en plus d’interet. L’objectif original de ce recueil est de contribuer a la reflexion sur l’adjectif dans les processus de construction du sens et en rapport avec les visees communicatives sous-jacentes. Sont prises en compte les relations que l’adjectif entretient dans le discours avec d’autres unites morphosyn-taxiques et la position qu’il occupe dans le syntagme, dans l’enonce, dans le texte. Les auteurs abordent les proprietes semantico-conceptuelles de l’ad-jectif et son role et ses apports discursifs sur fond d’approches theo-riques et de perspectives diverses : cognematique, submorphologique, cognitive, generativiste, guillaumienne, historiographique, compara-tif, contrastif, diachronique. Les langues etudiees dans les differentes contributions sont l’allemand, l’anglais, le bachkir, l’espagnol, le fran-cais, le hongrois, l’italien, le latin, le portugais, le russe, le vietnamien.

Self-determination theory (Ryan & Deci, 2017) has highlighted the differential roles that intrinsic life goals (for personal growth, close relationships, community connections, and physical health) and extrinsic life goals (i.e., for wealth, image, and status) play in supporting well-being. Less is known about how orientations toward these two types of aspirations develop. It is likely that early environmental influences, namely one's parents, impact individuals' aspirations. We address this gap by systematically reviewing the links between relevant parents' characteristics and the intrinsic and extrinsic goals of their children. We identified 49 eligible reports. Children's intrinsic aspirations were higher when parents provided a need-supportive environment (characterized by support for autonomy, relatedness, and competence) and when they endorsed intrinsic aspirations themselves, whereas children's extrinsic aspirations were higher when parents exhibited extrinsic aspirations themselves, promoted the pursuit of extrinsic aspirations, and provided environments characterized by need frustration. Therefore, fostering basic psychological need satisfaction may support children's intrinsic aspiring. In addition, parents should also be mindful of their own extrinsic goals, as they may influence extrinsic aspirations in their children and possibly compromise their well-being over the long term.

Human space exploration to date has been limited to low Earth orbit and the moon. The International Space Station (ISS), an orbiting laboratory 200 miles above the earth, provides a unique and incredible opportunity for researchers to prove out the technologies that will enable humans to safely live and work in space for longer periods of time and venture farther into the solar system. The ability to manufacture parts in-space rather than launch them from earth represents a fundamental shift in the current risk and logistics paradigm for human spaceflight. In particularly, additive manufacturing (or 3D printing) techniques can potentially be deployed in the space environment to enhance crew safety (by providing an on-demand part replacement capability) and decrease launch mass by reducing the number of spare components that must be launched for missions where cargo resupply is not a near-term option. In September 2014, NASA launched the 3D Printing in Zero G technology demonstration mission to the ISS to explore the potential of additive manufacturing for in-space applications and demonstrate the capability to manufacture parts and tools on-orbit. The printer for this mission was designed and operated by the company Made In Space under a NASA SBIR (Small Business Innovation Research) phase III contract. The overarching objectives of the 3D print mission were to use ISS as a testbed to further maturation of enhancing technologies needed for long duration human exploration missions, introduce new materials and methods to fabricate structure in space, enable cost-effective manufacturing for structures and mechanisms made in low-unit production, and enable physical components to be manufactured in space on long duration missions if necessary. The 3D print unit for fused deposition modeling (FDM) of acrylonitrile butadiene styrene (ABS) was integrated into the ISS Microgravity Science Glovebox (MSG) in November 2014 and phase I printing operations took place from November through December of that year. Phase I flight operations yielded 14 unique parts (21 total specimens) that could be directly compared against ground-based prints of identical geometry manufactured using the printer prior to its launch to ISS. The 3DP unit functioned safely and produced specimens necessary to advance the understanding of the critical design and operational parameters for the FDM process as affected by the microgravity environment. From the standpoint of operations, 3DP demonstrated the ability to remove parts from the build-tray on-orbit, teleoperate the printer from the ground, perform critical maintenance functions within defined human factors limits, produce a functional tool that could be evaluated for form/fit/function, and uplink a new part file from the ground and produce it on the printer. The flight parts arrived at NASA Marshall Space Flight Center in Huntsville, Alabama in April 2015, where they underwent months of testing in the materials and processes laboratory. Ground and flight prints completed the following phases of testing: photographic/visual inspection, mass and density evaluation, structured light scanning, XRay and CT, mechanical testing, optical microscopy, scanning electron microscopy, and chemical analysis. This presentation will discuss the results of this testing as well as phase II operations for the printer, which took place in June and July of 2016. Lessons learned from the tech demo and their impacts on the design and development of the second generation 3D printer for ISS, the Additive Manufacturing Facility (AMF) by Made In Space will also be presented. In addition, progress in other elements of NASA's In Space Manufacturing (ISM) initiative such as the on-demand ISM utilization catalog, in-space Recycler ISS Technology Demonstration development, launch packaging recycling, in-space printable electronics, development of higher strength polymeric materials for 3D printing and Additive Construction by Mobile Emplacement (ACME) will also be addressed.

We cannot understand contemporary psychology without first researching its history. Unlike other books on the history of psychology, which are chronologically ordered, this Handbook is organized topically. It covers the history of ideas in multiple areas of the field and reviews the intellectual history behind the major topics of investigation. The evolution of psychological ideas is described alongside an analysis of their surrounding context. Readers learn how eminent psychologists draw on the context of their time and place for ideas and practices, and also how innovation in psychology is an ongoing dialogue between past, present, and anticipated future.
