Research on media success factors is a fragmented field. Definitions, measures, and methods vary, and findings are often inconsistent. In an attempt to fill this perceived research gap, we distilled generic success factors of media products from the literature. Guided by theory and empirical findings, these factors were aggregated to complex concepts, building blocks of success that we further investigated in an exploratory qualitative study. We found that the building blocks are applicable to all types of media, independent of seriality and content types of media products. Subsequently the research question of this article is: Which building blocks of success are most important for media products? To answer this question, we conducted an online survey of 255 media professionals in print, audio-visual, and online media in Austria, Germany and Switzerland. To analyze our data, we deployed qualitative comparative analysis, a method based on set theory that is suitable to investigate complex causality. We conclude that four building blocks are necessary for success: “good” distribution, environmental orientation, form/design, and human resources are preconditions for achieving success in terms of audience market share. In addition, three patterns emerge in the sufficient paths (combinations of building blocks) to success. Which route to success a media product shows can be related to the width of its topical scope and the corresponding projected audience size.  相似文献

An external focus of attention is a conditio sine qua non for athletes: a response to Carson,Collins, and Toner (2015)     

Gabriele Wulf 《Journal of sports sciences》2016,34(13):1293-1295

In this invited response to a Letter to the Editor by Carson, Collins, and Toner (2015), I comment on various issues raised by the authors. I highlight the broad range of tasks and dependent measures used in studies comparing the effectiveness of external versus internal foci of attention. These studies – many of which involved sport skills – have consistently found performance or learning benefits when an external focus was adopted. There is no convincing evidence that performers’ preferences, or their familiarity with a certain focus, have a moderating effect. Anecdotal evidence reported by coaches who have compared the two types of foci is consistent with research findings. An external focus presumably promotes functional connectivity and contributes to goal-action coupling.  相似文献

Trajectory tracking for a quadrotor under wind perturbations: sliding mode control with state-dependent gains     

Gabriele Perozzi  Denis Efimov  Jean-Marc Biannic  Laurent Planckaert 《Journal of The Franklin Institute》2018,355(12):4809-4838

The problem of position tracking of a mini drone subject to wind perturbations is investigated. The solution is based on a detailed unmanned aerial vehicle (UAV) model, with aerodynamic coefficients and external disturbance components, which is introduced in order to better represent the impact of the wind field. Then, upper bounds of wind-induced disturbances are characterized, which allow a sliding mode control (SMC) technique to be applied with guaranteed convergence properties. The peculiarity of the considered case is that the disturbance upper bounds depend on the control amplitude itself (i.e. the system is nonlinear in control), which leads to a new procedure for the control tuning presented in the paper. The last part of the paper is dedicated to the analysis and reduction of chattering effects, as well as investigation of rotor dynamics issues. Conventional SMC with constant gains, proposed first order SMC, and proposed quasi-continuous SMC are compared. Nonlinear UAV simulator, validated through in-door experiments, is used to demonstrate the effectiveness of the proposed controls.  相似文献   

Perpetual Beginnings: The Role of Phenomenological Hermeneutics in Art Education     

Gabriele Esser-Hall 《The International Journal of Art & Design Education》2000,19(3):288-296

This paper reflects on the role of phenomenological hermeneutics as part of art history and theory programmes in art education. Though initially confined to Philosophy, this branch of hermeneutics can be utilised in Art Education also, as concepts explored here such as the appropriation of knowledge, interpretation, reading and understanding offer an effective tool to investigate the strength and potential of subjectivity, metaphoricity and embodiment in art practice. This paper begins with a reflection on the most effective space where theory teaching can take place and offers the concept of the hermeneutical space, where teaching is inclusive and supportive of self determined contributions to processes of theoretical reflection on art practice. A mutual learning experience is fostered in this environment, where teacher and student respect each other's readings. Finally, I put forward suggestions as to how this can be realised in an actual teaching situation by relating my own experience.  相似文献   

Autonomy enhances running efficiency     

Takehiro Iwatsuki  James W. Navalta  Gabriele Wulf 《Journal of sports sciences》2019,37(6):685-691

Performer autonomy has been shown to contribute to effective motor performance and learning. Autonomy support is therefore a key factor in the OPTIMAL theory of motor learning (Wulf, G., & Lewthwaite, 2016). The purpose of the present study was to examine whether supporting individuals’ need for autonomy by giving them choices would increase movement efficiency. Such a finding would be consistent with the OPTIMAL theory prediction that autonomy facilitates the coupling of goals and actions. Participants (N = 32) were asked to run at a submaximal intensity (65% of VO₂ max) for 20 minutes. Before the run, participants in a choice group were able to choose 5 of 10 photos as well as the order in which they would be shown to them on a computer screen during the run. Control group participants were shown the same photos, in the same order, chosen by their counterparts in the choice group. Throughout the run, oxygen consumption and heart rate were significantly lower in the choice group than the control group. Thus, providing autonomy support resulted in enhanced running efficiency. The present findings are in line with the notion that autonomy facilitates goal-action coupling.  相似文献   

Enhanced expectancies improve movement efficiency in runners     

Stoate I  Wulf G  Lewthwaite R 《Journal of sports sciences》2012,30(8):815-823

We followed up on recent findings demonstrating that enhancing performers' expectancies can improve their performance. Specifically, we examined whether providing experienced runners with positive feedback regarding their movement efficiency would increase running efficiency. Two groups of experienced runners ran on a treadmill at 75% of their maximum oxygen consumption (VO(2max)) for 10 min. One group (enhanced expectancy) was provided with (fabricated) feedback about the efficiency of their running style every 2 min. A control group was not given feedback. Oxygen consumption decreased in the enhanced expectancy group across measurement times (every 2 min for 10 min), but remained the same in the control group. In addition, performance perceptions changed only in the enhanced expectancy group, indicating a perception of greater ease of running and reduced fatigue when assessed after compared with before running. Finally, positive affect increased from a pre- to a post-test in the enhanced expectancy group, in contrast to the control group. Our findings show that enhanced expectancies can have a positive effect on movement efficiency and running experience. They add to the accumulating evidence for the social-cognitive-affective-motor nature of motor performance.  相似文献   

Feedback about more accurate versus less accurate trials: differential effects on self-confidence and activation     

Badami R  VaezMousavi M  Wulf G  Namazizadeh M 《Research quarterly for exercise and sport》2012,83(2):196-203

One purpose of the present study was to examine whether self-confidence or anxiety would be differentially affected byfeedback from more accurate rather than less accurate trials. The second purpose was to determine whether arousal variations (activation) would predict performance. On day 1, participants performed a golf putting task under one of two conditions: one group received feedback on the most accurate trials, whereas another group received feedback on the least accurate trials. On day 2, participants completed an anxiety questionnaire and performed a retention test. Shin conductance level, as a measure of arousal, was determined. The results indicated that feedback about more accurate trials resulted in more effective learning as well as increased self-confidence. Also, activation was a predictor of performance.  相似文献
