Interaction of external, introjected, and identified regulation with intrinsic motivation in exercise: Relationships with exercise enjoyment

The present study examined the way in which the exercise-related motives of external regulation, introjected regulation, and identified regulation interacted with intrinsic motivation to relate to exercise enjoyment. The study was conducted to test the "additive relationship hypothesis" emanating from Vallerand and Fortier's (1998) theoretical position regarding the interplay between extrinsic and intrinsic motivation in exercise. Exercise participants (N = 516) responded to a self-report questionnaire assessing their reasons for exercise participation before the commencement of a single exercise class. One week later, and immediately prior to the corresponding class, participants reported on their levels of exercise enjoyment. Interactional analyses using linear regression showed a significant interaction between identified regulation and intrinsic motivation. Specifically, the coexistence of high levels of identified regulation with high levels of intrinsic motivation corresponded with higher scores on exercise enjoyment. External regulation and introjected regulation did not interact with intrinsic motivation, thus supporting the research hypotheses. Collectively, the present findings supported the validity of Vallerand and Fortier's theoretical propositions in the exercise domain and specifically the additive relationship hypothesis between identified regulation and intrinsic motivation with respect to exercise enjoyment

Motives of Socially Responsible Business Conduct

The social and ecological challenges that governments face have raised their interest in socially responsible business conduct (SRBC). In this article we analyze the motives of executives to perform SRBC. We distinguish three types of motives: financial, ethical and altruistic motives. We test the hypotheses on a sample of 473 executives. The estimation results show that SRBC is driven by a combination of intrinsic and extrinsic motives, but that the intrinsic motives are stronger than the extrinsic motive.intrinsic motivation;extrinsic motivation;corporate social responsibility;socially responsible business conduct

Intrinsic Motivation, Job Autonomy and Turnover Intention in the Italian Healthcare: The mediating role of Affective Commitment

Drawing on Self-Determination and Work Characteristics theories, we hypothesized that job autonomy and intrinsic motivation were key exogenous variables positively related to affective commitment, which in turn is negatively related to turnover intention, by performing a mediating role. A sample of 442 nurses has been involved in this research. Through the cross-validation technique, the results showed that the hypotheses of this study were supported and affective commitment completely mediated the relationships between job autonomy, intrinsic work motivation and turnover intention. These findings have important implications for healthcare organizations by helping to promote effective work environments and major opportunities of responsibility to workers to develop their own activity. Conclusions were examined considering practical implications for organizations, employees and the need for further researches

Intrinsic flat stability of the positive mass theorem for graphical hypersurfaces of Euclidean space

The rigidity of the Positive Mass Theorem states that the only complete asymptotically flat manifold of nonnegative scalar curvature and zero mass is Euclidean space. We study the stability of this statement for spaces that can be realized as graphical hypersurfaces in Euclidean space. We prove (under certain technical hypotheses) that if a sequence of complete asymptotically flat graphs of nonnegative scalar curvature has mass approaching zero, then the sequence must converge to Euclidean space in the pointed intrinsic flat sense. The appendix includes a new Gromov-Hausdorff and intrinsic flat compactness theorem for sequences of metric spaces with uniform Lipschitz bounds on their metrics.Comment: 31 pages, 2 figures, v2: to appear in Crelle's Journal, many minor changes, one new exampl

The roles of political skill and intrinsic motivation in performance prediction of adaptive selling

Previous studies have long recognized and examined adaptive selling behavior as an effective selling behavior in current selling situations. Although some studies assumed and revealed moderating factors that affect the effectiveness of adaptive selling behavior, few studies examined an individual’s skill as a moderator on this effect. This study focuses on political skill as a type of skill that has been recently found to have positive effects on sales performance. In addition, this study includes intrinsic motivation as an additional moderator that enables political skill to be invested for effective selling behavior. Our analysis of 249 salespeople and 145 supervisors in a matching sample largely supports our hypotheses that the positive effects of adaptive selling behavior on sales performance are the highest when both political skill and intrinsic motivation are high

The Frequency Function of Elliptical Galaxy Intrinsic Shapes

We present fully nonparametric estimates of the frequency function of elliptical galaxy intrinsic shapes under the axisymmetric and triaxial hypotheses. If elliptical galaxies are assumed to be oblate or prolate, the frequency function of intrinsic shapes is negative for axis ratios near unity due to the lack of apparently round galaxies. Both axisymmetric hypotheses are found to be inconsistent at the 99 percent level with the data. Triaxial intrinsic shapes are fully consistent with the data; a number of possible triaxial frequency functions are presented, some of which exhibit strong bimodality. We also compute the ``maximum entropy'' distribution of intrinsic shapes under the triaxial hypothesis.Comment: uuencoded gziped PostScript, 22 pages including figures; To appear in The Astronomical Journal, Vol. 110, 199

Photometric Monitoring of the Gravitationally Lensed Ultraluminous BAL Quasar APM08279+5255

We report on one year of photometric monitoring of the ultraluminous BAL quasar APM 08279+5255. The temporal sampling reveals that this gravitationally lensed system has brightened by ~0.2 mag in 100 days. Two potential causes present themselves; either the variability is intrinsic to the quasar, or it is the result of microlensing by stars in a foreground system. The data is consistent with both hypotheses and further monitoring is required before either case can be conclusively confirmed. We demonstrate, however, that gravitational microlensing can not play a dominant role in explaining the phenomenal properties exhibited by APM 08279+5255. The identification of intrinsic variability, coupled with the simple gravitational lensing configuration, would suggest that APM 08279+5255 is a potential golden lens from which the cosmological parameters can be derived and is worthy of a monitoring program at high spatial resolution.Comment: 17 pages, with 2 figures.

User-generated content (UGC) in tourism: Benefits and concerns of online consumers

This study reports an attempt to enhance our understanding of the reasons behind virtual world usage. By providing a mixture of utilitarian and hedonic value, virtual worlds represent an emerging class of multipurpose information systems (MPIS). Previous research seems to fall short in explaining MPIS adoption, especially since key extrinsic and intrinsic motivators are not considered. Drawing upon IT adoption research, motivation theory and the consumer behavior literature, this research extends available works and provides insight into the influence and roles of extrinsic and intrinsic motivation. Hypotheses are postulated and tested using a sample of 1627 users of the virtual world Second Life. The results confirm the majority of the hypotheses and support the comprehensive model. The findings indicate instantaneous effects of extrinsic and intrinsic motivation, and highlight reinforcing effects of intrinsic motivation. Implications for research and practice are discussed
