The teaching of communication skills is a labour-intensive task because of the detailed feedback that should be given to learners during their prolonged practice. This study investigates to what extent our FILTWAM facial and vocal emotion recognition software can be used for improving a serious game (the Communication Advisor) that delivers a web-based training of communication skills. A test group of 25 participants played the game wherein they were requested to mimic specific facial and vocal emotions. Half of the assignments included direct feedback and the other half included no feedback. It was investigated whether feedback on the mimicked emotions would lead to better learning. The results suggest the facial performance growth was found to be positive, particularly significant in the feedback condition. The vocal performance growth was significant in both conditions. The results are a significant indication that the automated feedback from the software improves learners’ communication performances. 相似文献

AbstractRecently, researchers have used multilevel models for estimating intervention effects in single-case experiments that include replications across participants (e.g., multiple baseline designs) or for combining results across multiple single-case studies. Researchers estimating these multilevel models have primarily relied on restricted maximum likelihood (REML) techniques, but Bayesian approaches have also been suggested. The purpose of this Monte Carlo simulation study was to examine the impact of estimation method (REML versus Bayesian with noninformative priors) on the estimation of treatment effects (relative bias, root mean square error) and on the inferences about those effects (interval coverage) for autocorrelated multiple-baseline data. Simulated conditions varied with regard to the number of participants, series length, and distribution of the variance within and across participants. REML and Bayesian estimation led to estimates of the fixed effects that showed little to no bias but that differentially impacted the inferences about the fixed effects and the estimates of the variances. Implications for applied researchers and methodologists are discussed. 相似文献

AbstractIn the last years we have observed a growing interest in the use of gamification approaches for climate change education. While most practices are related to digital gaming, there is a new trend which is still academically unexplored: escape rooms. The main objective of this paper is to serve as an initial exploratory study in this field by identifying and analysing climate change-related escape rooms. For that purpose we carried out a web search and a qualitative content analysis. A total of 17 initiatives are described and compared, unravelling their main audience, country of origin, topics, scenarios and objectives covered. The paper also highlights what escape rooms can offer to climate change education: experiential and immersive learning, problem solving and critical thinking skills, and a sense of collaboration and urgency. 相似文献

The purpose of this study was to examine reciprocal associations between identity processes (commitment, in‐depth exploration, and reconsideration of commitment) and dimensions (support, negative interaction, and power) of maternal, paternal, and sibling relationships. A total of 497 Dutch families including 14‐years‐old adolescents (56.9% males), their fathers, mothers, and siblings, for a total of 1,988 respondents, participated in a five‐wave longitudinal study. Cross‐lagged analyses indicated that commitment and in‐depth exploration predicted improvements in family relationships (unidirectional effects), whereas reconsideration of commitment was predicted by low levels of maternal support and worsened the quality of the paternal relationship (reciprocal effects). These results were not moderated by adolescents' gender and sibling characteristics. Theoretical and practical implications are discussed. 相似文献

An algorithm for the assembly of multiple test forms is proposed in which the multiple-form problem is reduced to a series of computationally less intensive two-form problems. At each step, one form is assembled to its true specifications; the other form is a dummy assembled only to maintain a balance between the quality of the current form and the remaining forms. It is shown how the method can be implemented using the technique of O-1 linear programming. Two empirical examples using a former item pool from the LSAT are given—one in which a set of parallel forms is assembled and another in which the targets for the information functions of the forms are shifted systematically. 相似文献

We extend the Profit from Innovation (PFI) framework (Teece, 1986) by combining it with open innovation insights: we explore when and how managers make the transition between closed and open innovation, and how they use appropriation (formal and informal defense mechanisms) and project strategies to capture the value generated from the innovation at the project level. Based on a radical innovation project at Jaguar (UK), we contribute to a process and temporal perspective of open innovation by shedding light on two core project processes and their enabling mechanisms which influenced the ability of Jaguar to maximize profits from the innovation. The first core project process was the choice of timing of the shift from a closed to an open model of innovation: it was enabled by a pro-active change in the formal defense strategy (i.e. submission of a patent), and by an internal loose coupling project strategy that involved autonomy of the project champion and internal engineers’ weak membership in the project. The second core process was an external loose coupling project strategy that was enabled by the deployment of two complementary informal appropriation mechanisms namely, the reduction of the scope of tasks allocated to external partners combined with the development of guarded relationships with them. 相似文献

ABSTRACTWe propose a new performance measure for table tennis players: the mutual point-winning probabilities (MPW) as server and receiver. The MPWs quantify a player’s chances to win a point against a given opponent, and hence nicely complement the classical match statistics history between two players. These new quantities are based on a Bradley-Terry-type statistical model taking into account the importance of individual points, since a rally at 8–2 in the first set is less crucial than a rally at the score of 9–9 in the final set. The MPWs hence reveal a player’s strength on his/her service against a given opponent as well as his/her capacity of scoring crucial points. We estimate the MPWs by means of maximum likelihood estimation and show via a Monte Carlo simulation study that our estimation procedure works well. In order to illustrate the MPWs’ versatile use, we have organized two round-robin tournaments of ten respectively eleven table tennis players from the Belgian table tennis federation. We compare the classical final ranking to the ranking based on MPWs, and we highlight how the MPWs shed new light on strengths and weaknesses of the players. 相似文献

The stiffness measuring method for bicycle frames is not standardized, leading to a wide variety of test setups; they differ in many aspects such as applied load, support constraints and frame deflection measurement. The aim of this paper is to draw attention to this problem and to quantify the perturbing, unwanted side effects that influence the stiffness measurement of the bicycle frame. This is illustrated by developing a multi-purpose rating test method for bicycle frame stiffness. The proposed test rig design considers different aspects which should be taken into account when measuring the bicycle frame stiffness. In the experimental setup, it is observed that the contribution of the test bench compliance led to 21% difference in the frame stiffness results; the influence due to the head, the tube-bearing type the corresponding preload resulted in up to 19% difference in the stiffness results between the lowest and highest stiffness values measured; hysteresis effects caused by pulleys are estimated to introduce errors up to 11%; and the influence due to the operator variability and sensor accuracy is estimated to be less than 3%. 相似文献

ABSTRACTSelecting effective dietary strategies for professional football players requires comprehensive information on their energy expenditure (EE) and dietary intake. This observational study aimed to assess EE and dietary intake over a 14-day period in a representative group (n = 41) of professional football players playing in the Dutch Premier League (Eredivisie). Daily EE, as assessed by doubly labelled water, was 13.8 ± 1.5 MJ/day, representing a physical activity level (PAL) of 1.75 ± 0.13. Weighted mean energy intake (EI), as assessed by three face-to-face 24-h recalls, was 11.1 ± 2.9 MJ/day, indicating 18 ± 15% underreporting of EI. Daily EI was higher on match days (13.1 ± 4.1 MJ) compared with training (11.1 ± 3.4 MJ; P < 0.01) and rest days (10.5 ± 3.1 MJ; P < 0.001). Daily carbohydrate intake was significantly higher during match days (5.1 ± 1.7 g/kg body mass (BM)) compared with training (3.9 ± 1.5 g/kg BM; P < 0.001) and rest days (3.7 ± 1.4 g/kg BM; P < 0.001). Weighted mean protein intake was 1.7 ± 0.5 g/kg BM. Daytime distribution of protein intake was skewed, with lowest intakes at breakfast and highest at dinner. In conclusion, daily EE and PAL of professional football players are modest. Daily carbohydrate intake should be increased to maximize performance and recovery. Daily protein intake seems more than adequate, but could be distributed more evenly throughout the day. 相似文献
