Susan Otto's book, Designing Business Training for Fun and Results, highlights the design and development portions of the ADDIE instructional design model. Through situations, scenarios, and learner activities, Otto is able to give readers the opportunity to gain knowledge and experience about best practices. The book is written to engage readers while providing new activities and course techniques that can be implemented immediately.

The physiological load imposed on basketball players during competition     

S.E. McInnes  J.S. Carlson  C.J. Jones  M.J. McKenna 《Journal of sports sciences》2013,31(5):387-397

In this study, the intensities of activity and movement patterns during men's basketball were investigated by videoing the movements and monitoring the heart rate and blood lactate responses of eight elite players during competition. The results are expressed according to ‘live time’, which is actual playing time, and ‘total time’, which includes live time as well as all stoppages in play. The mean (± s.d.) frequency of all activities was 997 ± 183, with a change in movement category every 2.0 s. A mean total of 105 ± 52 high‐intensity runs (mean duration 1.7 s) was recorded for each game, resulting in one high‐intensity run every 21 s during live time. Sixty percent of live time was spent engaged in low‐intensity activity, while 15% was spent in high‐intensity activity. The mean heart rate (HR) during live time was 169 ± 9 beats min^‐l (89 ± 2% peak HR attained during laboratory testing); 75% of live time was spent with a HR response of greater than 85% peak HR. The mean blood lactate concentration was 6.8 ± 2.8 mM, indicating the involvement of glycolysis in the energy demands of basketball. It is concluded that the physiological requirements of men's basketball are high, placing considerable demands on the cardiovascular and metabolic capacities of players.  相似文献   

Structural assessment and measurement of the elastic deformation of historical violins: The case study of the Guarneri ‘del Gesù’ violin (1743) known as the ‘Cannone’     

Marco Fioravanti  Giacomo Goli  Bruce Carlson 《Journal of Cultural Heritage》2012,13(2):145-153

This paper presents a deformative and structural study of the Guarneri ‘del Gesù’ violin (1743) known as the ‘Cannone’. A structural assessment is fundamental to understanding the violin's compatibility with its residual function of musical instrument. The tuning of the instrument to a modern playing pitch during concerts could, in fact, cause stress resulting in plastic deformations of its structure. In order to understand the stress level to which the violin is subjected when tuned, several tests were performed. The forces acting on the bridge were measured, the geometry of the un-strung and of the tuned violin were acquired with a tri-dimensional scanner, the violin deformation was assessed by means of the computed surface deviation mesh and by measuring the deformation in selected lines, several sections of the violin were cut from the digital model and stress exerted on the sections was computed. The stress exerted on the neck, scroll and body were found to be very limited. More significant, albeit at a low level, was the stress exerted under the bridge between the sound holes. Mechanical stress exerted after tuning was found to be safe for the violin, if applied for a limited amount of time. This does not mean that the violin can be played freely, because the real strength of the material used in the violin is not known and mechanical stress during a concert must be added to time (viscous behaviour), moisture content variation (mechano-sorptive behaviour) and hygro-thermal stress, thus worsening the condition. The method presented here could be applied to compute the level of stress of any violin.  相似文献   

Neural Correlates of Decision Making on a Gambling Task     

Stephanie M. Carlson  Vivian Zayas  Amy Guthormsen 《Child development》2009,80(4):1076-1096

Individual differences in affective decision making were examined by recording event-related potentials (ERPs) while 74 typically developing 8-year-olds (38 boys, 36 girls) completed a 4-choice gambling task (Hungry Donkey Task; E. A. Crone & M. W. van der Molen, 2004 ). ERP results indicated: (a) a robust P300 component in response to feedback (punishment vs. reward outcomes), (b) anticipation effects (stimulus-preceding negativity) prior to outcomes presented on frequent (vs. infrequent) punishment choices, (c) anticipation effects prior to selections associated with short and long-term losses (vs. gains), and (d) individual differences in ERP components were significantly correlated with behavioral performance and verbal ability. These findings suggest that neurophysiological responses may be an index of children's trait-based and/or developmental level of decision-making skills in affective–motivational situations.  相似文献   

Hurricane Sandy Exposure Alters the Development of Neural Reactivity to Negative Stimuli in Children          下载免费PDF全文

This study examined whether exposure to Hurricane Sandy‐related stressors altered children's brain response to emotional information. An average of 8 months (M_age = 9.19) before and 9 months after (M_age = 10.95) Hurricane Sandy, 77 children experiencing high (n = 37) and low (n = 40) levels of hurricane‐related stress exposure completed a task in which the late positive potential, a neural index of emotional reactivity, was measured in response to pleasant and unpleasant, compared to neutral, images. From pre‐ to post‐Hurricane Sandy, children with high stress exposure failed to show the same decrease in emotional reactivity to unpleasant versus neutral stimuli as those with low stress exposure. Results provide compelling evidence that exposure to natural disaster‐related stressors alters neural emotional reactivity to negatively valenced information.  相似文献   

Validity of the diagnostic category of attention deficit disorder without hyperactivity: a review of the literature   总被引：4，自引：0，他引：4  

B B Lahey  C L Carlson 《Journal of learning disabilities》1991,24(2):110-120

The validity of the diagnostic category of Attention Deficit Disorder Without Hyperactivity (ADD/WO) has been the subject of debate since it was first introduced in DSM-III. The differentiation of two syndromes of ADD is supported by factor analytic studies that indicate two dimensions of maladjustment: (1) inattention and disorganization, and (2) motor hyperactivity and impulsive responding. Cluster analyses of these two dimensions have yielded two profiles of deviance that correspond to the DSM-III subtypes. Furthermore, clinic-referred children who meet DSM-III criteria for ADD/WO have been shown to exhibit less serious conduct problems, are less impulsive, are more likely to be characterized as sluggish and drowsy, are less rejected by peers but more socially withdrawn, and are more likely to exhibit depressed mood and symptoms of anxiety disorder than children with Attention Deficit Disorder with Hyperactivity (ADD/H).  相似文献

Transfer of persistence across reinforced behaviors     

Robert Eisenberger  Robert Terborg  Jeffrey Carlson 《Learning & behavior》1979,7(4):493-498

Rats barpressed for food on a variable-interval schedule and then received food in a runway for one of three degrees of effort. Finally, all animals again barpressed for food. Requiring five runway shuttles per food pellet produced a greater subsequent rate of barpressing than reward for each shuttle, which, in turn, yielded more barpressing than free food. A follow-up study showed the five-shuttle treatment to produce more subsequent barpressing than a control condition which omitted any runway treatment. Another experiment indicated that the higher rate of barpressing following the five-shuttle treatment was not due to greater conditioned general activity, since the five-shuttle treatment failed to increase the number of grid crossings to the cue of food presentation and produced no more unconditioned barpressing than following free food in the runway. Two possible interpretations of the results were compared: (1) The degree of accustomed effort per reinforcer becomes a generalized component of instrumental behavior, (2) high effort increases the habituation of frustration-produced disruptive responses.  相似文献
