Geographic and substance use data were collected from 301 urban adolescents to compare the perceived and observed risk and safety associated with their home and activity space locations (routine locations). The geographic characteristics of the neighborhood surrounding each location was summarized according to features theorized to be risky, such as criminal activity and alcohol sales, and feat...

In this paper we present SCMS-ER: Small Cell Management System Emergency Recovery. SCMS-ER provides a way of backing up Small Cell Management System critical data across two geographic locations. It also provides a plan for replication of backup data so that the client data is recoverable in the event of a disaster on the main site. Keywords—small cell, Femto cell, redundancy, geographic redund...

INTRODUCTION: Perception of beauty is influenced by geographic, ethnic, cultural, and demographic factors. However, objective measurements remain the foundation for esthetic evaluations. In the quest to better define the “ideal” female buttock, this study assumes interdependence between variables such as country of residence, sex, age, occupation, and esthetic perception, yielding a waist to hi...

Maruca vitrata Fabricius (Lepidoptera: Crambidae) is a polyphagous insect pest that feeds on a variety of leguminous plants in the tropics and subtropics. The contribution of host-associated genetic variation on population structure was investigated using analysis of mitochondrial cytochrome oxidase 1 (cox1) sequence and microsatellite marker data from M. vitrata collected from cultivated cowpe...

Determining seafood geographic origin is critical for controlling its quality and safeguarding the interest of consumers. Here, we use trace element fingerprinting (TEF) of bivalve shells to discriminate the geographic origin of specimens. Barium (Ba), manganese (Mn), magnesium (Mg), strontium (Sr) and lead (Pb) were quantified in cockle shells (Cerastoderma edule) captured with two fishing met...

When sampling locations are known, the association between genetic and geographic distances can be tested by spatial autocorrelation or regression methods. These tests give some clues to the possible shape of the genetic landscape. Nevertheless, correlation analyses fail when attempting to identify where genetic barriers exist, namely, the areas where a given variable shows an abrupt rate of ch...

We analyze how increased use of electronic channels affects geographic price variance by enabling buyers to shift demand across locations. Using data from the wholesale automotive market from 2003 to 2008, we find that buyers use the reach of the electronic channels to shift purchases from high-price to low-price locations. This " arbitrage " reduces the variance of market prices, but not their...

Placozoans, flat free-living marine invertebrates, possess an extremely simple bauplan lacking neurons and muscle cells and represent one of the earliest-branching metazoan phyla. They are widely distributed from temperate to tropical oceans. Based on mitochondrial 16S rRNA sequences, 19 haplotypes forming seven distinct clades have been reported in placozoans to date. In Japan, placozoans have...

This paper studies the distribution of firm productivity and production in a network of geographic locations. Using firm-level data from China’s manufacturing sector from 1998 to 2007, we document that, on average, firms’ geographic locations explain approximately 14% of the productivity dispersion, yet the explanatory power of locations varies significantly across industries. These empirical p...

A new approach is presented that allows a user agent to compute a compact browser cookie-like character string (called Geocookie) for a third party, whereby for any given geographic location the third party can either infer that the location is definitely not covered by the Geocookie, or it can infer that the location is probably covered by the Geocookie, depending on whether the user agent has...
