BACKGROUND Regional trade agreements are major international policy instruments that shape macro-economic and political systems. There is widespread debate as to whether and how these agreements pose risks to public health. Here we perform a comprehensive systematic review of quantitative studies of the health impact of trade and investment agreements. We identified studies from searches in Pub...

Trade-offs play pivotal roles in the ecology and evolution of natural populations. However, trade-offs are probably not static, invariant relationships. Instead, ecological factors can shift, alter, or reverse the relationships underlying trade-offs and create critical genotype x environment (G x E) interactions. But which ecological factors alter trade-offs or create G x E interactions, and wh...

Synopsis There is great concern among the public in general, and consumers in particular, about the quality of the environment in relation to agriculture. Such concerns focus on issues such as pollution from agriculture, the quality of landscapes, animal welfare and food safety. As a result, many countries have developed a range of standards, codes of good practice and other policy measures. Th...

BACKGROUND It is ethically controversial whether medical doctors are morally permitted to ration the care of their patients at the bedside. To explore whether general practitioners in fact do ration in this manner we conducted a study within primary care in the Danish public healthcare system. The purpose of the study was to measure the extent to which general practitioners (GPs) would be willi...

this paper explores the capabilities of multi-objective particle swarm optimization algorithmin a simulation-optimization model for solving waste load allocation problems. the main goals are totaltreatment costs, violation of the water quality standards and equity. in this research, the water qualitysimulation model is coupled with a multi-objective optimization model, mopso. in order to derive...

Many computations exhibit a trade off between execution time and quality of service. A video encoder, for example, can often encode frames more quickly if it is given the freedom to produce slightly lower quality video. A developer attempting to optimize such computations must navigate a complex trade-off space to find optimizations that appropriately balance quality of service and performance....

Economies across the globe are working towards strengthening quality of governance to promote a conducive environment for trade and investment. The study is an attempt empirically examine impact on India’s with 23 Asian partners period from 2000 2019. In order determinants trade, employs both static as well dynamic panel regression models. We also form index capture indicators using principal c...

Visual short-term memory (VSTM) is limited in the quantity and quality of items that can be retained over time. Importantly, these two mnemonic parameters interact: increasing the number of items in VSTM reduces the quality with which they are represented. Here, we ask whether this trade-off is under top-down control. Specifically, we test whether participants can strategically optimise the tra...

This study focuses on the relationship between trade and relative prices of pollution intensive goods. Seminal to this idea is the transfer problem. It is based on the idea that environmental quality of two countries that engage in trade could be affected and this could also have possible environmental quality transfer effects in a third country (geographic neighbors or trade partners) and a re...
