In this election year, U.S. national spending on health care will reach $2.8 trillion, or about 18% of total spending on all goods and services. This high level of spending reduces our ability to invest in other important parts of the economy and also adds to our unsustainable national debt. There is wide agreement that we must find ways to bend the health care cost curve. Taking different appr...
The traditional linear industries led to dwindling resources and even exhaustion, as well as worsening pollution, it is a short-sighted unsustainable developing mode of the economy. Ecological industry is to realize the harmonious development between economy and environment by planning industrial systems according to material cycle in the natural ecological system. The Eco-industry coordinates ...
There is a growing consensus that human beings must cut greenhouse gas emissions to mitigate global warming and the resultant impacts on the environment. However, production optimisation has rarely taken this issue into consideration, often leading to environmentally unsustainable operation decisions. This paper presents a lot sizing batch optimisation model for a stochastic make-toorder produc...
Paradigms of sustainable exploitation focus on population dynamics of prey and yields to humanity but ignore the behavior of humans as predators. We compared patterns of predation by contemporary hunters and fishers with those of other predators that compete over shared prey (terrestrial mammals and marine fishes). Our global survey (2125 estimates of annual finite exploitation rate) revealed t...
Continuous and intensive exploitation of wildlife resources by early agricultural societies had major ecological consequences in the ancient Near East. In particular, hunting strategies of post-Neolithic societies involving the mass killing of wild ungulates contributed to the eventual extirpation of a number of wild species. A remarkable deposit of bones of Persian gazelle (Gazella subgutarosa...
As long-chain fatty acids (LCFA) of the n-3 series are critically important for human health, fish consumption has considerably increased in recent decades, resulting in overfishing to respond to the worldwide demand, to an extent that is not sustainable for consumers' health, fisheries economy, and marine ecology. In a recent study, it has been shown that whole rye (WR) consumption improves bl...
For remote underdeveloped and sparsely populated regions, the use of national power grids to provide electricity can be both unsustainable and impractical. In recent years, decentralised renewable power has gained popularity, endowing social benefits to the local inhabitants through clean rural electrification. However, power reliability and system autonomy are often the primary technical conce...
BACKGROUND Fumaric acid is a commercially important component of foodstuffs, pharmaceuticals and industrial materials, yet the current methods of production are unsustainable and ecologically destructive. RESULTS In this study, the fumarate biosynthetic pathway involving reductive reactions of the tricarboxylic acid cycle was exogenously introduced in S. cerevisiae by a series of simple genet...
Developing nations like Namibia are aiming to industrialize much like developed nations and use the gross domestic product to measure their progress. However, this development path has been largely unsustainable. For Namibia to develop into a sustainable society, a different approach is needed. This study aimed to find entry points toward such an approach. Surveys were conducted in Windhoek, Na...
