Power generation mix and electricity price

Featured Database

Author: Stringer, Thomas; Joanis, Marcelin; Abdoli, Shiva Description: Electricity prices are influenced by the composition of the power generation mix. Firms that operate in sectors that are energy-intensive, such as manufacturing, metallurgy or oil and gas, are vulnerable to variations in electricity price. Everyday citizens, faced with increasing costs of living, also experience a strain on their finances when electricity prices rise. As many countries move towards a net-zero energy transition, energy policy enacted to change the power generation mix of electricity markets is under increased scrutiny. Little research has…

Economic, Societal, and Environmental Impacts of Available Energy Sources: A Review

Featured Database

Author: Al Mubarak, Faisal; Rezaee, Reza; Wood, David A. Description: The impacts that the available energy sources have had on society, the environment, and the economy have become a focus of attention in recent years, generating polarization of opinions. Understanding these impacts is crucial for rational evaluation and the development of strategies for economic growth and energy security. This review examines such impacts of the main energy resources currently exploited or in development, including fossil fuels, geothermal, biomass, solar, hydropower, hydrogen, nuclear, ocean, and wind energies on society through analysis…

Winners and losers of generative AI: Early Evidence of Shifts in Freelancer Demand

Featured Database

Author: Teutloff, Ole; Einsiedler, Johanna; Kassi, Otto; Braesemann, Fabian; Mishkin, Pamela; del Rio-Chanona, R. Maria Description: We examine how ChatGPT has changed the demand for freelancers in jobs where generative AI tools can act as substitutes or complements to human labor. Using BERTopic we partition job postings from a leading online freelancing platform into 116 fine-grained skill clusters and with GPT-4o we classify them as substitutable, complementary or unaffected by LLMs. Our analysis reveals that labor demand increased after the launch of ChatGPT, but only in skill clusters that were…

The Psychology of Authenticity

Featured Database

Author: Newman, George E. Description: Perceptions of authenticity (or, inauthenticity) have been shown to affect people’s judgments and behavior across a wide variety of domains. However, there is still ambiguity about how the concept should be defined. This is attributable, at least in part, to a growing list of different “kinds of authenticity” with little discussion of the potential overlaps between them. The goal of this paper is to reduce these various notions of authenticity into a more manageable set of constructs. Building on the work of Newman and Smith,…

Nitrate and Brain/CNS Cancer Diagnoses in the First Year of Life

Featured Database

Author: Sajid, Arshi; Semprini, Jason Description: Nitrates in drinking water, common in agricultural states like Iowa, pose health risks to young infants. This brief first reviews the plausible biological mechanisms linking nitrate exposure to brain and central nervous system (BCNS) cancers in the first year of life. We then linked historic water quality and cancer registry data at the county level to construct linear and quantile regression models estimating the association between a BCNS diagnosis and nitrate measures. We found significantly higher nitrate levels preceding pediatric zero-year-old BCNS cancer diagnoses….

Trends in nitrate contamination: implications for communities reliant on groundwater for drinking

Featured Database

Author: Jayasekera, D. Harshanee; Munde, Siddhi; Snow, Daniel D.; Rimšaitė, Renata Description: Nebraska’s vulnerability to nitrate contamination in water systems is highlighted by agrochemical inputs with leaching potential and the state’s reliance on groundwater for drinking. Nitrate is a regulated compound in drinking water due to its association with methemoglobinemia and other chronic health conditions. This study examines water quality in Nebraska’s groundwater over several decades, focusing on temporal and spatial variations in nitrate concentrations across different well types. The findings reveal increasing statewide trends in nitrate levels, with considerable…

The association between increases in nitrate in drinking water and colorectal cancer incidence rates in California, USA

Featured Database

Author: Cisneros, Ricardo; Amiri, Marzieh; Gharibi, Hamed Description: PURPOSE: The water resources in California are polluted with nitrate (NO3) due to the ever-increasing application of nitrogen-based fertilizers. Considering the potential connection between NO3 in drinking water and the incidence rate of colorectal cancer, this study aims to investigate the association between long-term exposure to NO3 via drinking water and the incidence of colorectal cancer from 2010 to 2015 in California. METHODS: A total of 56,631 diagnoses of colorectal cancer were recorded from 2010 to 2015. A generalized linear model was…

Agricultural Compounds in Water and Birth Defects

Featured Database

Author: Brender, Jean D.; Weyer, Peter J. Description: Agricultural compounds have been detected in drinking water, some of which are teratogens in animal models. The most commonly detected agricultural compounds in drinking water include nitrate, atrazine, and desethylatrazine. Arsenic can also be an agricultural contaminant, although arsenic often originates from geologic sources. Nitrate has been the most studied agricultural compound in relation to prenatal exposure and birth defects. In several case-control studies published since 2000, women giving birth to babies with neural tube defects, oral clefts, and limb deficiencies were…

Disparities in potential nitrate exposures within Iowa public water systems

Featured Database

Author: Mantey, Emmanuel Padmore; Liu, Lu; Rehmann, Chris R. Description: Nitrates (measured as nitrate-nitrogen) in drinking water exceeding the maximum contaminant level (MCL) of 10 mg L-1 can cause significant health risks, such as methemoglobinemia. Even long-term exposure to concentrations below the MCL can also increase the risks of cancer. Iowa, a major agricultural producer, has grappled with decades-long nitrate pollution in its water systems due to intensive farming practices and animal feeding operations. To help in developing interventions and policies to protect public health, this study delves into long-term…
