Gentrification - the process in which higher income (and often younger) households displace lower income residents of a city neighborhood - has been occurring in many urban neighborhoods over the last few decades. This process changes the demographics, and often the essential character, of the neighborhood. As a result, we...
On 6 February 2007, President Bush announced that the United States would
create a new military command for Africa, to be known as Africa Command or Africom.
Throughout the Cold War and for more than a decade afterwards, the U.S. did not have a
military command for Africa; instead, U.S....
This study analyzed the differences between three habitats in and around EcoMinga’s Cerro Candelaria Reserve, which protects part of the Llanganates – Sangay Ecological Corridor in the eastern cloud forest of Ecuador. The EcoMinga Foundation began reforestation efforts in several abandoned pastures in the reserve in 2008, which have since... and This project would not have been possible without the support and kindness of the El Placer community. Thanks to Piedad Recalde for her constant care, humor, and enormous amounts of delicious food. Thanks to Jesús Recalde and Darwin Recalde for their companionship in the field and invaluable insights on the...
The surge in "unconventional" oil projects such as Alberta's Tar Sands in the last decade signals a shift in global production from relatively accessible conventional reserves to "frontier" oil. This paper examines one aspect of the oil/environment tension – the environmental regulatory system surrounding the tar sands – by adopting...
It has been hypothesized that mindfulness-based programs with a primary focus on teaching self-compassion or empathy will have greater effects on self-compassion and empathy than will mindfulness-based exposure programs, which focus primarily on enhancing present moment awareness and reducing distress. However, because research on mindfulness-based exposure programs has centered on...
Negative emotional behaviors, such as criticism, defensiveness, contempt, and stonewalling, that spouses may show during conflict are key predictors of marital dissatisfaction. Existing research has focused on middle-class couples, but little is known about how these negative emotional behaviors predict marital satisfaction among couples from socioeconomically diverse backgrounds. The present...

Microbiome 10, 206 (2022). https://doi.org/10.1186/s40168-022-01412-x and Background: Effective surveillance of microbial communities in the healthcare environment is increasingly important in infection prevention. Metagenomics-based techniques are promising due to their untargeted nature but are currently challenged by several limitations: (1) they are not powerful enough to extract valid signals out of the background noise for low-biomass samples,...
This paper describes the technology and methods deployed in the continuous autonomous remote monitoring of cracks in interior and exterior walls of a residence near a limestone quarry. The object is to quantitatively compare crack response to blast-induced ground motion to that induced by diurnal temperature changes, weather fronts, and...
The aviation industry is set to see another significant leap in new technology, namely electric aircraft. As of the time of this research, both 9-seat and 19-seat aircraft would be ready to be launched by air service providers under the Essential Air Service (EAS) program. While electric aircraft manufacturers are...
