SPATIAL HETEROGENEITY AND THE WAGE CURVE REVISITED* [PDF]

Journal of Regional Science, 2006
ABSTRACTMost “wage curve” studies ignore the geography of local labor markets. However, when a local labor market is in close proximity of other labor markets, a local shock that increases unemployment may not lead to lower pay rates if employers fear outward migration of their workers.

Identifying the Spatial Heterogeneity and Driving Factors of Satellite-Based and Hydrologically Modeled Profile Soil Moisture

Remote Sensing
Profile soil moisture (PSM), the soil water content in the whole soil layer, directly controls the major processes related to biological interaction, vegetation growth, and runoff generation.

Resource competition and coexistence in heterogeneous metacommunities: many-species coexistence is unlikely to be facilitated by spatial variation in resources [PDF]

PeerJ, 2013
There is little debate about the potential of environmental heterogeneity to facilitate species diversity. However, attempts to show the relationship between spatial heterogeneity and diversity empirically have given mixed results.

Spatial Heterogeneity in the Tumor Microenvironment [PDF]

Cold Spring Harbor Perspectives in Medicine, 2016
Recent developments in studies of tumor heterogeneity have provoked new thoughts on cancer management. There is a desperate need to understand influence of the tumor microenvironment on cancer development and evolution. Applying principles and quantitative methods from ecology can suggest novel solutions to fulfil this need.

The impact of user spatial heterogeneity in heterogeneous cellular networks [PDF]

2014 IEEE Globecom Workshops (GC Wkshps), 2014
The spatial distribution of users in cellular networks plays an important role on network performance. It is becoming increasingly common in the recent literature to model the user locations according to a homogeneous Poisson point process, yet users are often spatially clustered in reality.

Spatial Heterogeneity of Field Capacity of Chernozem Soil in Northeast of China

Guan'gai paishui xuebao, 2021
【Background】 The soil moisture characteristic has the obvious spatial heterogeneity, and the determination of its spatial heterogeneity is the theoretical basis for the precision management of soil water.

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Leukemia and Exposure to Potential Benzene Sources in Children From the Mexico City Metropolitan Area, 2010–2021: A Geospatial Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Leukemia is the most common childhood cancer in Mexico, and acute lymphoblastic leukemia (ALL) is the most frequent subtype. Exposure to high concentrations of benzene has been associated with ALL incidence, particularly in urban areas. This study evaluated the relationship between distance to benzene emission sources and the number

On evolutionary spatial heterogeneous games [PDF]

Physica A: Statistical Mechanics and its Applications, 2008
How coperation between self-interested individuals evolve is a crucial problem, both in biology and in social sciences, that is far from being well understood. Evolutionary game theory is a useful approach to this issue. The simplest model to take into account the spatial dimension in evolutionary games is in terms of cellular automata with just a one ...
