Mexican consumers' attitudes toward irradiated and imported apples

Agribusiness, EarlyView.
Abstract This study centers on analyzing Mexican consumers' willingness to pay (WTP) for imported US fresh apples subjected to irradiation, contrasting it with the more prevalent postharvest chemical treatments. We collect data using a survey tool in Qualtrics designed to explore the impact of information dissemination through two distinct narrative ...

Using life‐history trait variation to inform ecological risk assessments for threatened and endangered plant species

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 213-223, January 2023., 2023
Abstract Developing population models for assessing risks to terrestrial plant species listed as threatened or endangered under the Endangered Species Act (ESA) is challenging given a paucity of data on their life histories. The purpose of this study was to develop a novel approach for identifying relatively data‐rich nonlisted species that could serve

Can outsourcing pest and disease control help reduce pesticide expenditure? Evidence from rice farmers

Agribusiness, EarlyView.
Abstract Outsourcing pest and disease control (PDC) has grown rapidly worldwide, especially in developing countries. Although numerous studies have investigated various advantages of outsourcing PDC, little is known about its impact on pesticide expenditure.

Are standard aquatic test species and methods adequate surrogates for use in environmental risk assessment of pesticides in tropical environments?

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 202-212, January 2023., 2023
Abstract In regulatory risk assessment, surrogate species of fish, aquatic invertebrates, and primary producers are tested to assess toxicity and subsequently the risk of pesticides to freshwater biota. This study evaluates whether the standard, surrogate test species (mostly temperate in latitudinal distribution) used in many parts of the world are ...

Optimal Control of a Malaria Model with Long-Lasting Insecticide-Treated Nets [PDF]

arXiv, 2020
A deterministic multi-stage malaria model with a non-therapeutic control measure, the use of mosquito bednet is formulated and analyzed. The model basic reproduction number is derived, and analytical results show that the models equilibria are locally and globally asymptotically stable when certain threshold conditions are satisfied.

How Competitive Is Myanmar's Rice Sector? A Comparison of Production Costs and Efficiency

Agribusiness, EarlyView.
ABSTRACT This paper analyzes the cost competitiveness of rice production in Myanmar by examining production costs, cost efficiency, and the potential effect of improving cost efficiency on the country's global competitiveness. To achieve this, we conduct a comparative analysis of production costs among major rice‐producing countries and estimate the ...

National characterization of pesticide runoff and erosion potential to put USEPA standard ecological scenarios in context for pyrethroids

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 175-190, January 2023., 2023
Abstract Decision‐making for pesticide registration by the US Environmental Protection Agency (USEPA) relies upon crop‐specific scenarios in a tiered framework. These standard modeling scenarios are stated to represent “…sites expected to produce runoff greater than would be expected at 90% of the sites for a given crop/use.” This study developed a ...

Analysis and optimal control of a malaria mathematical model under resistance and population movement [PDF]

arXiv, 2020
In this work, two mathematical models for malaria under resistance are presented. More precisely, the first model shows the interaction between humans and mosquitoes inside a patch under infection of malaria when the human population is resistant to antimalarial drug and mosquitoes population is resistant to insecticides.
