Symposium: Effects of Human Choices on Characteristics of Urban Ecosystems [PDF]

open access: yes, 2007
Most urban ecology in cities remains an “ecology in cities” rather than an “ecology of cities.” Accomplishing the latter requires the inclusion of humans within the concept of “ecosystem,” both how humans alter the properties of urban ecosystems and how ...

Cool Kitchen: Processing Starch and Eggshell Powder into Sustainable Coatings for Passive Daytime Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A food‐grade cooling composite made from starch and recycled eggshell powder offers a scalable, ultra‐low‐cost solution for passive daytime radiative cooling. Easily prepared using basic kitchen tools, this material empowers communities, even in areas with limited infrastructure, to stay cooler during worsening summer heat waves.

Prenatal Human Ecology

open access: yesAmerican Journal of Public Health and the Nations Health, 1960
I DOUBT THAT ten years from now sessions like this will be held on the subject of "pregnancy wastage." The challenge is less that of salvaging waste than of developing a prenatal public health. There are at least three reasonable objectives of this public health of pregnancy: to reach demographic equilibrium before it is forced on future generations by

Naturalizing ethics [PDF]

open access: yes, 2007
In this essay we provide (1) an argument for why ethics should be naturalized, (2) an analysis of why it is not yet naturalized, (3) a defense of ethical naturalism against two fallacies—Hume’s and Moore’s—that ethical naturalism allegedly commits, and ...

Measuring telomere length and telomere dynamics in evolutionary biology and ecology [PDF]

open access: yes, 2014
Telomeres play a fundamental role in the protection of chromosomal DNA and in the regulation of cellular senescence. Recent work in human epidemiology and evolutionary ecology suggests adult telomere length (TL) may reflect past physiological stress and ...

Functional Materials for Environmental Energy Harvesting in Smart Agriculture via Triboelectric Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...
