This slide presentation reviews the technology advancements plans for the NASA Technology Area 1, Launch Propulsion Systems Technology Area (LPSTA). The draft roadmap reviews various propulsion system technologies that will be developed during the next 25 + years. This roadmap will be reviewed by the National Research Council which will issue a final report, that will include findings and recommendations.
The purpose of the present study was to test a self‐determination theory model with the following hypotheses: (1) Patients’ autonomous causality personality orientation and oral health care professionals’ autonomy‐supportive treatment styles, as perceived by patients, would both be positively indirectly associated with dental attendance through patients’ autonomous motivation for dental treatment. (2) Patients’ controlled causality personality orientation and oral health care professionals’ controlling treatment styles, as perceived by patients, would both be positively indirectly associated with avoidance of making a dental clinic appointment through patients’ anxiety for dental treatment. A sample size of about 200 patients was estimated to be acceptable in detecting moderate effect sizes (independent variables: 5–6; power: .80; p < .05). Student patients ( N = 226) responded to a survey with validated questionnaires. Using LISREL , both hypotheses were supported. In addition, patients’ perception of a controlling treatment style moderated the controlled personality—dental anxiety relation, so that a lower controlling treatment style mitigated dental anxiety substantially among patients with a high control orientation. Effect sizes were moderate to large. Analyses ( Z ‐scores) also revealed that the autonomous personality is more strongly linked to situational autonomous motivation than situational autonomy support, whereas a controlled personality and a perceived controlling treatment style are equally and significantly associated to dental anxiety. Both patient personalities and oral health care professionals’ treatment styles are substantially linked to autonomous motivation and anxiety for dental treatment, which are relatively strongly associated with dental attendance and avoiding dental clinic appointments, respectively.

The performance of anyone at his job is affected by a combination of ability and motivation. This book brings together papers which represent the main work being done in the study of motivation. There are three main approaches to the subject. The first is paternalistic in nature and assumes that the more a worker is rewarded, the harder he will work. The second approach assumes that a person will be motivated to work if rewards and penalties are tied directly to his performance. The third approach is that called participative management in which the incentives for effective performance are in the job itself or in the individual's relationship with members of his working team.
Every teacher and every parent faces the question of how to foster more versus less motivation in students. Theories of motivation, accordingly, must be able to both describe the nature of human motivation, and prescribe methods by which it can be fostered or undermined. However, because most prior theories of motivation have conceptualized motivation as a unitary phenomenon, one that varies from very little motivation to act to a great deal of it, they have been critically hamstrung in providing any practical advice to educators and parents.
The concept of a human need for relatedness is among the oldest and most generative topics in psychology. Yet despite the considerable attention relatedness has received, some basic aspects of this important construct remain poorly understood. Specifically, the literature to this point has been inconclusive with regard to how one’s lifetime experiences of relatedness may be related to how much individuals value additional or new experiences of relatedness. The present investigation directly addressed this question using a multimethod approach. Three studies found consistent support for a positive association between person-level relatedness and the incremental value of new relatedness experiences. That is, those who reported having experienced more relatedness in their lives nevertheless reported anticipating and extracting more affective value from additional social encounters. By contrast, those having experienced less relatedness in life reported less incremental value—a pattern consistent with a process of person-level accommodation or desensitization.
The regulation of behavior takes many forms, not all of which are volitional or have the full support
If the LD field is to make important breakthroughs in coming years, it must avoid becoming insular and parochial. There are important ideas to be gleaned from the work of individuals not enmeshed with the specific problems we confront everyday. Individuals outside the LD field can bring fresh perspectives that allow us to see beyond the boundaries of our current frameworks and procedures. They often see what's missing and suggest important connecting links to improve the way we understand and deal with learning disabilities. As an example of the potential value of soliciting outside viewpoints, we asked Edward Deci and his colleague Cristine Chandler to read over the papers included in the series of articles on “The Future of the LD Field” and to analyze and comment on our field's future from the perspective of Deci's distinguished work on human psychology. The result is a provocative discussion that first reviews the papers in the future series with reference to definition, etiology, prevention, and treatment, and then suggests that a key element missing in most of the presentations is a sophisticated and systematic concept of human motivation. Deci and Chandler offer a brief outline of basic psychological concepts not widely discussed in the LD field and apply these concepts with regard to both the treatment of learning disabilities and to the processes used to support and supervise the efforts of teachers. Their analysis and ideas have profound implications for LD theory, research, and practice, and warrant careful attention from those concerned with advancing the field.—Howard S.

Language acquisition is among the most interesting and complex arenas in which to study human motivation, learning, and educational strategies.Children of course, not only learn their first languages without need of external controls or rewards-they find energy and joy in the process.They are inherently drawn to speech, they love to play with sounds, words, and meanings, and they take interest in verse, song, and written expression.Parents watch this unfolding with their own joy and engagement, as they mimic and elaborate on their child's speech, read to them, and narrate events.Children growing up in multilingual environments will afford this stimulation and interest across languages.

This chapter reviews the history of theory and research on subjective vitality within self-determination theory (SDT). Research on subjective vitality, defined as the phenomenal experience of aliveness and of having energy available to the self, has demonstrated the centrality of this experience of energy to wellness and flourishing. Research has shown that subjective vitality varies not only with physical conditions but also with different types and conditions of motivation. Generally, more autonomous motives are associated with enhanced vitality, whereas controlled motives diminish subjective energy. Findings also show that satisfaction of basic psychological needs enhances subjective vitality, whereas need frustrations deplete one’s sense of energy and aliveness. Experimental work on “ego depletion,” in which self-controlling motives are induced, leading to lowered energy, is consistent with this SDT-based theorizing. Subjective vitality has been studied in many domains, beginning with exercise and physical activity and extending to areas such as health and wellness, sleep, energy in the workplace, and the importance of nature to the experience of vitality. Across contexts and characters, subjective vitality remains one of the most phenomenally accessible and predictive indicators of wellness available.
