Hedonic-motivation systems (HMS) -- systems used primarily to fulfill users' intrinsic motivations -- are the elephant in the room for IS research. Growth in HMS sales has outperformed ...utilitarian-motivation systems (UMS) sales for more than a decade, generating billions in revenue annually; yet IS research focuses mostly on UMS. In this study, researchers explain the role of intrinsic motivations in systems use and propose the HMS adoption model (HMSAM) to improve the understanding of HMS adoption. The HMSAM extends van der Heijden's (2004) model of hedonic system adoption by including cognitive absorption (CA) as a key mediator of perceived ease of use (PEOU) and of behavioral intentions to use (BIU) HMS. Results from experiments involving 665 participants confirm that, in a hedonic context, CA is a more powerful and appropriate predictor of BIU than PEOU or joy, and that the effect of PEOU on BIU is fully mediated by CA sub-constructs.
This landmark volume offers a collection of conceptual papers and empirical research studies that investigate the dynamics of language learning motivation from a complex dynamic systems perspective. ...The contributors include some of the most well-established scholars from three continents, all addressing the question of how we can understand motivation if we perceive it as continuously changing and evolving rather than as a fixed learner trait. The data-based studies also provide useful research models and templates for graduate students and scholars in the fields of applied linguistics and SLA. This collection of conceptual papers and data-based research studies investigate the dynamics of language learning motivation from a complex dynamic systems perspective. The chapters seek to answer the question of how we can understand motivation if we perceive it as a continuously changing and evolving entity rather than a fixed learner trait.
For successful motivation of professionals, it is important to understand accurately their goals, values and job expectations. Theories of motivation suggest different motives to improve ...productivity, but their effectiveness is not sufficiently validated in case of IT professionals. This study uses empirical data from online surveys of information technology professionals. The purpose of the study is to identify the factors that motivate professionals to work more efficiently, initiatively and productively. The results of the study show that to effectively solve the problem of motivating IT professionals, it is useful to use different theories of motivation, combine these theories and construct new concepts of motivation.
Self-determination theory proposes a multidimensional conceptualization of motivation comprising autonomous and controlled forms. Whereas autonomous motivation relates positively to individuals' ...optimal functioning (e.g., well-being, performance), controlled motivation is less beneficial. To be able to use self-determination theory in the field of organizational behaviour, the Multidimensional Work Motivation Scale was developed and tested using data from 3435 workers in seven languages and nine countries. Factorial analyses indicated that the 19-item scale has the same factor structure across the seven languages. Convergent and discriminant validity tests across the countries also indicate that the psychological needs for autonomy, competence, and relatedness as well as the theoretically derived antecedents to work motivation (e.g., leadership and job design) are predictably related to the different forms of motivation, which in turn are predictably related to important work outcomes (e.g., well-being, commitment, performance, and turnover intentions). Implications for the development of organizational research based on self-determination theory are discussed.
Aktuell rauchen in Deutschland 28,7 % der 18- bis 64-Jährigen (26,1 % der Frauen/31,2 % der Männer). Bei den 12- bis 17-Jährigen liegt die Raucherquote mit 7,4 % auf einem historischen Tiefstand. ...Auch bei den 18- bis 25-Jährigen ist die Raucherquote in den letzten Jahren rückläufig. Sie liegt aktuell bei 26,1 %.Wichtigstes Ziel der bundesweiten Maßnahmen der Bundeszentrale für gesundheitliche Aufklärung (BZgA) in der Tabakprävention ist die Reduzierung der Raucherquote. Hierzu führt die BZgA die „rauchfrei“-Kampagne durch, die sich zielgruppenspezifisch an Jugendliche und Erwachsene richtet. Mit einem eng verzahnten und kontinuierlich überprüften und weiterentwickelten Maßnahmenmix werden die Zielgruppen im Internet, in ihren Lebenswelten (Personalkommunikation) sowie über Medien und Massenkommunikation erreicht. Neben der Information über die Risiken des Rauchens und Passivrauchens spielen hierbei die Motivation zum Rauchstopp und die qualitätsgesicherte Unterstützung bei der Raucherentwöhnung eine wichtige Rolle.Die Maßnahmen der BZgA werden auf der Basis repräsentativer Befragungen zum Rauchverhalten der 12- bis 25-Jährigen, die die BZgA regelmäßig durchführt, überprüft und weiter entwickelt. Auf dieser Grundlage werden neue Produkte, wie E‑Zigaretten, E‑Shishas oder Tabakerhitzer, und neue Konsumtrends, wie der Trend zum Wasserpfeifenrauchen, integriert. Zugangswege zu den Zielgruppen werden vor dem Hintergrund der Digitalisierung der Gesellschaft kontinuierlich überprüft und die gesundheitsförderliche Ausgestaltung von Lebenswelten unterstützt. Insgesamt bietet die „rauchfrei“-Kampagne ein qualitätsgesichertes Maßnahmenspektrum, welches kontinuierlich weiterentwickelt wird.
The usage of imprecise probabilities has been advocated in many domains: A number of philosophers have argued that our belief states should be “imprecise” in response to certain sorts of evidence, ...and imprecise probabilities have been thought to play an important role in disciplines such as artificial intelligence, climate science, and engineering. In this paper I’m interested in the question of whether the usage of imprecise probabilities can be given a practical motivation (a motivation based on practical rather than epistemic, or alethic concerns). My aim is to challenge the central motivation for using imprecise probabilities in decision-making that has been offered in the literature: the idea that, in at least some contexts, it’s desirable to be ambiguity averse. If I succeed, this will show that we need to reconsider whether there are good reasons to use imprecise probabilities in contexts in which making good decisions is what's of primary concern.
