This paper studies the problem of estimating geographical locations of images. To build reliable geographical estimators, an important question is to find distinguishable geographical clusters in the world. Those clusters cover general geographical regions and are not limited to landmarks. The geographical clusters provide more training samples and hence lead to better recognition accuracy. Pre...

Samples of phytobenthos were collected during three different seasons in 2005 along a linear transect of a lowland peat bog at various spatial scales (10 cm, 1 m, 10 m) to investigate the seasonal dynamics, diversity, and factors influencing the spatial patterns of microalgal communities. Non-metric multidimensional scaling (NMDS), similarity percentage (SIMPER) analyses, ANOSIM, Mantel tests a...

Evaluating the impact of scholarly papers plays an important role for addressing recruitment decision, funding allocation and promotion, etc. Yet little is known how actual geographic distance influences the impact of scholarly papers. In this paper, we leverage the law of geographic distance and citations between different institutions to weight quantum Pagerank algorithm for objectively measu...

In this study we apply hierarchical spectral partitioning of bipartite graphs to a Dutch dialect dataset to cluster dialect varieties and determine the concomitant sound correspondences. An important advantage of this clustering method over other dialectometric methods is that the linguistic basis is simultaneously determined, bridging the gap between traditional and quantitative dialectology. ...

Not so long ago, using maps on the Web was difficult. If you could find them at all, they were ugly and slow to load and came with clunky user interfaces. This has all changed thanks to the Google Map service. In recent years, commercial sites such as Amazon, eBay, and Google have increasingly become platforms that support complex user ecosystems. Using openly published APIs, you can look up an...

We test a conditional version of the International Capital Asset Pricing Model (ICAPM) accounting for the deviations from Purchasing Power Par...

This paper investigates the effect of market entry of new firms on incumbent firms’ innovative activity measured as patent applications. The basic assumption is that the effect of entry varies by geographical distance between entrants and incumbents due to the presence of localized unobserved spillovers. In order to avoid endogeneity problems commonly associated with the timing of entry and ent...

This paper analyses the effect of locally bounded knowledge spillovers on regional differences in growth. A model will be developed that allows spillovers to take place across regions. Certain conditions determine the amount of spillovers a region receives. By use of simulations (with randomised parameter constellations), it is possible to examine the general behaviour of the model. It is found...

This study examines how email is utilized to enact maintenance behaviors in interpersonal relationships and explores whether geographic distance between individuals affects this process. Two hundred twenty-six college students accumulated personal email messages over a one-week period. These emails were coded using Canary and Stafford’s (1994) maintenance strategy topology. Results indicate tha...
