This study explores the linguistic application of bipartite spectral graph partitioning, a graphtheoretic technique that simultaneously identifies clusters of similar localities as well as clusters of features characteristic of those localities. We compare the results using this approach to previously published results on the same dataset using cluster and principal component analysis (Shacklet...

In classical routing protocols, geographical distances/locations are typically used as the metric to select the best route, under the assumption that shorter distances exhibit lower energy consumption and nodes within the communication range of the sender can receive packets with a certain success probability. However, in underwater acoustic sensor networks (UASNs), sound propagation in the oce...

Psychotherapy and psychosocial interventions rely mainly on verbal communication and language. With the expanding use of computers as well as the capacity of the Internet to bridge geographic distances and to increase access, computer mediated communication (CMC) plays an increasing role for the delivery of psychosocial interventions. This chapter focuses on the advantages and limitations of CM...

Received: 5 March 2009 Revised: 7 March 2010 Accepted: 10 March 2010 Online publication date: 1 July 2010 Abstract Cross-national distance is a key concept in the field of management. Previous research has conceptualized and measured cross-national differences mostly in terms of dyadic cultural distance, and has used the Euclidean approach to measuring it. In contrast, our goal is to disaggrega...

It has been hypothesized that, in species exhibiting natal philopatry, genetically related individuals would have home ranges closer to each other than those of unrelated individuals. Using radiotelemetry (2001–2003) and genetic data from 35 female Florida black bears (Ursus americanus floridanus), we tested the hypothesis that genetic relatedness among individuals influenced the spatial organi...

This paper studies the effect of supplier-customer relationship on supplier innovation through a knowledge spillover channel. We use the geographical distance between a supplier and its major customers to capture knowledge spillovers along the supply chain. To establish causality, we explore plausibly exogenous variation in distance caused by customer headquarters relocations. In a difference-i...

We synthesize the financial crisis contagion literature through the gravity model from physics and test the hypothesis that the severity of contagion relates positively to trade and financial linkages but negatively to psychic distance between countries, when macroeconomic fundamentals and institutional factors are controlled. The psychic distance variable, a behavioral predictor constructed al...

The Internet’s tremendous value is undoubtedly dependent on its universal connectivity among a great number of heterogeneous networks that are distributed over the world. In recent years, while the Internet’s scale has expanded exponentially, the current status of its connectivity is still in the lack of comprehensive and formal study. In this paper, we contribute to the understanding of Intern...
