Bio-Economies of Scope and the Discard Problem in Mulitple Species Fisheries [PDF]

open access: yes
This paper considers the problem of multi-species fisheries management when targeting individual species is costly and at-sea discards of fish by fishermen are unobserved by the regulator.

Bioinspired Flexible and Stretchable Coil Structure from Ti3C2Tx MXene/AgNPs‐Functionalized Piezoelectric Nanofibers for Enhanced Energy Harvesting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Ti3C2Tx MXene and Ag nanoparticles are embedded into piezoelectric nanofibers to form a stretchable, self‐powered coil that converts mechanical deformation into electrical energy. The device enables controllable power output during stretching and release while maintaining a compact and lightweight architecture, making it suitable for miniaturized ...

On a Problem of Proving the Existence of an Equilibrium in a Large Economy without Free Disposal: A problem of a purely finitely additive measure arising from the Fatou's lemma in several dimensions [PDF]

open access: yes
It is well-known in the literature that the free disposability or the desirability of all the commodities is needed to ensure the existence of an equilibrium in a large economy with a continuum of economic agents.

Environmentally Adjusted Elasticity Measures [PDF]

open access: yes
Here, using input, output and nitrogen pollution data related to one state, we propose to extend the elasticity concept to include environmental pollution treated as undesirable output to provide the environmentally adjusted elasticity measures for the ...

Detecting violations of the monotonicity condition under the assumption of weak disposability in eco-DEA models

open access: yesCentral European Journal of Operations Research
Abstract Data envelopment analysis (DEA) was originally developed to evaluate entities (firms, regions, countries, etc.) that carry out production processes in which multiple inputs are converted into multiple outputs and for which prices as a valuation system are (partially) unavailable.

Capillary Electrophoresis With Amperometric Detection for Neurotransmitter Analysis: Principles, Electrode Materials, Methodologies, and Applications

open access: yesELECTROPHORESIS, EarlyView.
This review provides a comprehensive summary of monoamine neurotransmitter analysis by capillary electrophoresis with amperometric detection. Fundamental principles of amperometric detection, electrode positioning strategies, and approaches to high‐voltage decoupling are described, followed by a critical comparison of electrode materials, selection of ...

The Theory of By-Production of Emissions and Capital-Constrained Non-Cooperative Nash Outcomes of a Global Economy [PDF]

open access: yes
The reduced form approaches that are commonly adopted in the literature to model emission-generating technologies (EGTs) do not distinguish between emission-causing and non-emission causing goods in production.
