We demonstrate that the 1st- and 2nd-order characteristics of a visual stimulus can have a profound influence on each other in terms of perceived position. We use the parameter of spatial separation to selectively manipulate the effect of one characteristic upon the other. 1st-order features have their largest effect upon the perceived position of 2nd-order structure when separation is small, w...

This study analyzed German and Nso mothers' auditory, proximal, and visual contingent responses to their infants' nondistress vocalizations in postnatal Weeks 4, 6, 8, 10, and 12. Visual contingency scores increased whereas proximal contingency scores decreased over time for the independent (German urban middle-class, N = 20) but not the interdependent sociocultural context (rural Nso farmers, ...

Technological change has led to a dramatic decline in the cost of communication and in the cost of coordinating activities performed in different locations. This has allowed firms in rich countries to fragment their production process and offshore an increasing share of the value chain to low-wage countries. 2 Richard Baldwin (2006) refers to this phenomenon as the “second unbundling.” In his w...

Research on curiosity has undergone 2 waves of intense activity. The 1st, in the 1960s, focused mainly on curiosity's psychological underpinnings. The 2nd, in the 1970s and 1980s, was characterized by attempts to measure curiosity and assess its dimensionality. This article reviews these contributions with a concentration on the 1st wave. It is argued that theoretical accounts of curiosity prop...

The IS research community has paid significant attention to climate change and other ecological problems. However, the communities own environmental footprint has been subject to little research so far. This work reports on the results of a Life Cycle Assessment that was conducted to identify the main determinants for the environmental footprint of an IS conference. It brings up the painful sub...

The idea is pretty similar to the idea of extension from 1-dimension to 2-dimensions. A point in 1-dimension is represented in R as x or y. If we take two copies of R, we get the space R ⊗ R in which we can represent a 2-dimensional point i.e. we go from x → (x, y). The operation ⊗ is known as direct product. Let us now examine how we can write a two particle state using two single particle sta...
