Recent experiments on the ski simulator produced ambiguous results and raised unanswered questions concerning the true nature of "novice" behavior and the occurrence of behavioral changes during learning. The aim of the present experiment was to analyze the evolving behavior of three beginners during six practice sessions on a ski simulator The position of the apparatus platform was recorded as time series and used for constructing dynamical models, including stiffness and damping functions. The results showed that novices tended to exploit a Rayleigh damping behavior during the first trials and then transition toward a van der Pol damping. These results replicate previous observations by Nourrit, Delignieres, Caillou, Deschamps, and Lauriot (2003) and suggest the transition to the expert behavior could arise early in practice, when the task is of moderate difficulty. The discussion focuses on the properties of the observed learning dynamics and proposes a global conceptualization for acquiring complex motor skills. 相似文献

The mechanical responses (i.e. external contact forces and external power) of 25 elite rowers to a race-pace rowing protocol were investigated on the traditional fixed stretcher mechanism and the more recently introduced free-floating stretcher mechanism rowing ergometers. Using a Rowperfect rowing ergometer for both conditions, external contact forces at the handle, stretcher and sliding seat, as well as the displacements of the handle and stretcher, were recorded. The external power was calculated as the product of the force and velocity data from both the handle and stretcher. Significant differences (P < 0.05) between the two conditions for each mechanical parameter were observed. The fixed condition showed larger maximum values for forces and external power and average power throughout the rowing cycle. Moreover, rowing with the fixed mechanism generated higher inertial forces during the transition between the propulsion and recovery phases, especially at the catch of the cycle. The results suggest that: (i) muscular coordination may differ according to the stretcher mechanism used, which could have an impact on the physiological adaptations of muscles; and (ii) the free-floating mechanism may induce lower catch and maximum values for net joint forces and net joint moments that could decrease the risk of injury. 相似文献

The purpose of the present research was to test the applicability of the Dualistic Model of Passion (Vallerand et al., 2003) to being a sport (football) fan. Three studies provided support for this dualistic conceptualization of passion. Study 1 showed that harmonious passion was positively associated with adaptive behaviours (e.g. celebrate the team's victory), whereas obsessive passion was positively associated with maladaptive behaviours (e.g. risking losing one's job to go to a game). Study 2 used a short Passion Scale and showed that harmonious passion was positively related to the positive affective life of fans during the 2006 FIFA World Cup, psychological health (self-esteem and life satisfaction), and public displays of adaptive behaviours (e.g. celebrate the team's victory into the streets), whereas obsessive passion was predictive of maladaptive affective life (e.g. hating opposing teams' fans) and behaviours (e.g. mocking opposing teams' fans). Finally, Study 3 examined the role of obsessive passion as a predictor of partner's conflict that in turn undermined partner's relationship satisfaction. Overall, the present results provided support for the Dualistic Model of Passion. The conceptual and applied implications of the findings are discussed. 相似文献

In the last decade we have entered the era of remote controlled military technology. The excitement about this new technology
should not mask the ethical questions that it raises. A fundamental ethical question is who may be held responsible for civilian
deaths. In this paper we will discuss the role of the human operator or so-called ‘cubicle warrior’, who remotely controls
the military robots behind visual interfaces. We will argue that the socio-technical system conditions the cubicle warrior
to dehumanize the enemy. As a result the cubicle warrior is morally disengaged from his destructive and lethal actions. This
challenges what he should know to make responsible decisions (the so-called knowledge condition). Nowadays and in the near
future, three factors will influence and may increase the moral disengagement even further due to the decrease of locus of
control orientation: (1) photo shopping the war; (2) the moralization of technology; (3) the speed of decision-making. As
a result, cubicle warriors cannot be held reasonably responsible anymore for the decisions they make. 相似文献

In the economics of schooling literature, input substitutions have been identified as the major difficulty in assessing school and teacher effectiveness. In this paper we examine whether a teacher's grading practice can improve students' academic achievements by reducing these input substitutions. We use the teacher-student interaction model of Correa and Gruver (1987) to enhance the specification of the traditional production functions of students' academic achievements by introducing a teacher grading parameter in these functions. Under specific conditions, Correa and Gruver show that a student may respond either positively or negatively to the teacher's greater effort and/or harder grading, depending upon the student's preferences; thus the issue of an efficient grading practice is, as usual in the economics of education research, an empirical issue. To implement the econometric specification of the model, we define a latent grading variable from an error components specification on class grade regressions. This variable is used to explain the students' grade specific standardized test results for a sample of first and fourth-graders of Montreal francophone public elementary schools. 相似文献
