Theoretical analyses within the broad field of social learning research give mixed conclusions on whether the shape of a diffusion
curve can be used to infer that a learned trait increases through social or asocial learning. Here we explore how factors
such as task structure (e.g., multiple-step tasks), task abandonment, subgoal learning, and neophobia affect the shape of
the diffusion curve for both asocially learned and socially learned behavior. We demonstrate that, whereas social learning
increases the likelihood of S-shaped curves, sigmoidal patterns can be generated by entirely asocial processes, and cannot
be reliably interpreted as indicators of social learning. Our findings reinforce the view that diffusion curve analysis is
not a reliable way of detecting social transmission. We also draw attention to the fact that task structure can similarly
confound interpretation of network-based diffusion analyses, and suggest resolutions to this problem. Supplemental materials

Pacing offers a potential avenue for enhancement of endurance performance. We report here a novel method for characterizing pacing in 800-m freestyle swimming. Websites provided 50-m lap and race times for 192 swims of 20 elite female swimmers between 2000 and 2013. Pacing for each swim was characterized with five parameters derived from a linear model: linear and quadratic coefficients for effect of lap number, reductions from predicted time for first and last laps, and lap-time variability (standard error of the estimate). Race-to-race consistency of the parameters was expressed as intraclass correlation coefficients (ICCs). The average swim was a shallow negative quadratic with slowest time in the eleventh lap. First and last laps were faster by 6.4% and 3.6%, and lap-time variability was ±0.64%. Consistency between swimmers ranged from low-moderate for the linear and quadratic parameters (ICC = 0.29 and 0.36) to high for the last-lap parameter (ICC = 0.62), while consistency for race time was very high (ICC = 0.80). Only ~15% of swimmers had enough swims (~15 or more) to provide reasonable evidence of optimum parameter values in plots of race time vs. each parameter. The modest consistency of most of the pacing parameters and lack of relationships between parameters and performance suggest that swimmers usually compensated for changes in one parameter with changes in another. In conclusion, pacing in 800-m elite female swimmers can be characterized with five parameters, but identifying an optimal pacing profile is generally impractical. 相似文献

Identifying match events that are related to match outcome is an important task in football match analysis. Here we have used generalised mixed linear modelling to determine relationships of 16 football match events and 1 contextual variable (game location: home/away) with the match outcome. Statistics of 320 close matches (goal difference ≤ 2) of season 2012–2013 in the Spanish First Division Professional Football League were analysed. Relationships were evaluated with magnitude-based inferences and were expressed as extra matches won or lost per 10 close matches for an increase of two within-team or between-team standard deviations (SD) of the match event (representing effects of changes in team values from match to match and of differences between average team values, respectively). There was a moderate positive within-team effect from shots on target (3.4 extra wins per 10 matches; 99% confidence limits ±1.0), and a small positive within-team effect from total shots (1.7 extra wins; ±1.0). Effects of most other match events were related to ball possession, which had a small negative within-team effect (1.2 extra losses; ±1.0) but a small positive between-team effect (1.7 extra wins; ±1.4). Game location showed a small positive within-team effect (1.9 extra wins; ±0.9). In analyses of nine combinations of team and opposition end-of-season rank (classified as high, medium, low), almost all between-team effects were unclear, while within-team effects varied depending on the strength of team and opposition. Some of these findings will be useful to coaches and performance analysts when planning training sessions and match tactics. 相似文献

The paper analyzes five historical fictions for children in the Batang Historyador (Young Historian) series which detail five
periods in Philippine history. The books discuss the issues of child labor in precolonial Philippines, child labor and the
right to education regardless of gender during the Spanish colonial period, child labor during the American Occupation, children
as witnesses of history in the Japanese Occupation and Martial Law periods. The narratives reveal (consciously or unconsciously)
how distortedly and inaccurately the past is told from the perspective of a colonized mind. The struggles of historians to
review and revision history from a pro-Filipino consciousness were totally unheeded. The works attempt to throw light on issues
of class, gender and children’s rights but Filipino issues regarding culture, identity, politics and history were obliterated
because the framework was tied to a “universal” notion of history.

Distracted driving is a problem on U.S. roadways. Strategic campaigns have tried to curb this behavior with varying success. Researchers are examining how distracted-driving simulators might be useful in helping to combat this epidemic. Participants (N = 193) took part in a pretest/posttest, between-subjects field experiment where they were randomly assigned to one of five video game driving simulation scenarios (e.g., texting/talking/two combo conditions/distraction-free). Results indicated that participants texting during simulation committed more crashes, fog line crossings, and speed infractions than those talking and those who were not distracted. Further, results indicated that the simulation experience led to reports of being less likely to drive distracted in the future. 相似文献
