Taking a largely empirical approach this paper addresses the global spread of new technologies by defining two diffusion margins – the extensive, referring to the spreading of first use across economies and the intensive, referring to the intensity of use within economies. Using data relating to mail services we indicate the relative importance of the intensive and extensive margins in global diffusion over time. Using data on steamships and the basic oxygen process for steelmaking we also explore whether there are international spillovers in the diffusion process. We find evidence of spillovers which appear more likely to be negative than positive. 相似文献

Abstract It is currently not known whether human responses across typical sports surfaces are dependent on cushioning or frictional properties of the interface. The present study assessed systematic changes in surface cushioning (baseline acrylic, rubber, thin foam, and thick foam) as participants performed tennis running forehand foot plants wearing a basic neutral shoe (plimsolls). It was hypothesized that systematic decreases in peak rates of loading, heel pressures, and perceived hardness would be yielded as surface cushioning increased (impact test device). A common acrylic top surface provided consistent frictional properties across surfaces. Kinetics (AMTI, 960 Hz and Footscan Pressure Insoles, 500 Hz), kinematics (Peak MOTUS, 120 Hz), and cushioning perception were assessed. Peak and mean loading rates of vertical ground reaction force, peak horizontal force, peak heel pressure, and rates of loading demonstrated significant correlations (P < 0.05) with the participants' perceived levels of cushioning and matched mechanical rankings of surface cushioning. In contrast, peak impact force was lowest on the least cushioned surface. Kinematic responses were not significantly different between surfaces. Present evidence supports ‘‘peak rate of loading'' as a more suitable indicator of surface cushioning than peak impact force. Although cautionary, biomechanical support is also provided for mechanical methods of surface cushioning assessment. 相似文献

According to self-determination theory (SDT), the extent to which students’ motivation is self-determined is critical for academic performance. SDT also proposes that self-determined academic motivation is facilitated when the learning environment supports the basic psychological needs for autonomy, relatedness, and competence. This model of social support → needs satisfaction → motivation → learning outcomes is termed the general SDT model. Current evidence regarding this general SDT model is limited, in that, to date, no study has examined it in full using within-individual methods, which are critical for understanding inner psychological processes and mechanisms. Using a large and comprehensive college student dataset (total N of responses = 30,765), the current study aims to apply a within-individual analytical approach to the general SDT model. Specifically, we apply a cross-classified path model to account for both the between-student level and between-classroom level nesting structure. This model enables us to explain the relationships between the variables in the general SDT model on three levels: situational (within-student and within-classroom), between-student, and between-classroom.The results generally support the predictions on all three levels. For a student, a classroom, or a student’s specific experience within a classroom, the general SDT model received support. Most importantly, when the same student in the same classroom experiences higher levels of autonomy support, she or he is more likely to have her or his psychological needs satisfied and to study for self-determined reasons, which are associated with higher perceived learning performance. Various unexpected results, such as the direct effects of learning climate and the predominance of the competence need, are also reported. Overall, the current research provides a comprehensive and multilevel understanding of the role of self-determination in college classrooms. 相似文献
