Economic impact on tooth emergence.
As shown in nearly 10,000 Negro and White boys and girls between 4.5 and 16.5 years of age, poverty-level children (with an income-toneeds ratio of 1.0) tend to be delayed in permanent tooth emergence as compared with those approximating median per-capita income. For boys, a per-capita income difference of $2200 was associated with a 0.15 standard deviation difference in emergence timing of 28 ...
متن کاملThe impact of external events on the emergence of social herding of economic sentiment
We investigate the impact of an exogenous environment on the emergence of social herding of economic sentiment. An interactions-driven dynamics of economic sentiment is modeled by an Ising model on a large (two-dimensional) square lattice. The individual states are called optimism and pessimism. The exogenous environment is modeled as a sequence of random events, which might have a positive or ...
متن کاملThe Impact of External Events on the Emergence of Collective States of Economic Sentiment
We investigate the impact of the environment (i.e. the impact of socio-political and socio-economic exogenous events) on the emergence of ordered phases of locally interacting individual economic sentiment variables (consumer confidence, business confidence etc.). The sentiment field is modeled as a (non-critical) Ising field with nearestneighbor interactions on a (two-dimensional) square latti...
متن کاملEconomic emergence: An evolutionary economic perspective
The standard neoclassical approach to economic theorizing excludes, by definition, economic emergence and the related phenomenon of entrepreneurship. We explore how the most economic of human behaviours, entrepreneurship, came to be largely excluded from mainstream economic theory. In contrast, we report that evolutionary economists have acknowledged the importance of understanding emergence an...
متن کاملDevelopmental communalities in tooth emergence timing.
Intercorrelations and communalities are now well known for tooth formation (Garn et al., J Dent Res 39:1049, 1960), crown size of the permanent teeth (Moorees and Reed, Arch Oral Biol 9:685, 1964; Garn et al., J Dent Res 44:350, 1965), the deciduous teeth (Garn et al., JDentRes 56:1214, 1977), and crown size of deciduous teeth during odontogenesis (Garn et al., J Dent Res 58:554, 1979). However...
