Consumer Food Waste Behaviors In Relation To Open Date Label Misinterpretation, Daniel Hutchings, Elisabeth Seliga, Anya O'Meara, Anna Blank Apr 2021

Consumer Food Waste Behaviors In Relation To Open Date Label Misinterpretation, Daniel Hutchings, Elisabeth Seliga, Anya O'Meara, Anna Blank

Thinking Matters Symposium

In the United States, the legal framework for product date labeling is minimal and varies across states. Manufacturers have the discretion to use any date label that they deem appropriate, and this lack of uniformity leaves room for misinterpretation by both retailers and consumers. Previous studies have examined consumer misinterpretation of date labels and how this lack of knowledge correlates to food waste behaviors. This study was aimed at understanding how consumers apply their knowledge about date labels to make decisions about purchasing and discarding food. The research was conducted via an intercept survey outside of a grocery store to …


Wildlife Trade And Covid-19: Towards A Criminology Of Anthropogenic Pathogen Spillover, Piers Beirne Phd Dec 2020

Wildlife Trade And Covid-19: Towards A Criminology Of Anthropogenic Pathogen Spillover, Piers Beirne Phd

Department of Criminology

The general remit of this paper is the role of wildlife trade in pathogen spillover. Its underlying assumption is that, so far from being the exclusive domain of the life sciences, the study of pathogen spillover will be greatly enhanced by multi-perspectival approaches, including One Health and those employed here, namely, non-speciesist green criminology and critical animal studies. The paper moves from discussions of zoonosis, anthroponosis and wildlife trade to the emergence of COVID-19 in Wuhan, China. The paper recommends the abolition of all wildlife trade and the reclamation of wildlife habitat and broaches discussion of the extension of legal …


Snowshoe Hares (Lepus Americanus) Alter Feeding Behavior In Response To Coyote (Canis Latrans) And Moose (Alces Alces) Cues At Diverse Vegetation Densities, Zachary K. Lankist Apr 2019

Snowshoe Hares (Lepus Americanus) Alter Feeding Behavior In Response To Coyote (Canis Latrans) And Moose (Alces Alces) Cues At Diverse Vegetation Densities, Zachary K. Lankist

Student Scholarship

Prey interpret predator cues as a warning and use them to assess the danger of a given area. Multiple prey species avoid chemical cues from predators at feeding sites because the risk of death outweighs the benefit of food. However, we lack information regarding avoidance of chemical cues from competitors as well as how foraging behavior changes alongside vegetative cover. To test if chemical cues and veget~tive cover alter prey vigilance, number of visits, and time spent at feeding sites, I observed snowshoe hares (Lepus americanus) in plots containing coyote (Canis latrans; predator) and moose (Alces alces; competitor) urine across …


Changes In Spring Arrival Times: Climate Change And The Phenology Of Spring Bird Migration, Aaron Svedlow Apr 2019

Changes In Spring Arrival Times: Climate Change And The Phenology Of Spring Bird Migration, Aaron Svedlow

Student Scholarship

Climate change and weather affect the phenology of bird migration; however, specific climatological factors associated with these observed effects have only recently been described. The relationship between local, regional, and global climate patterns and avian migration are increasingly important to understand due to the widespread, and potentially negative, implications (such as reduced fecundity) of rapid human induced climate change on bird populations. Migratory birds are under selective pressure to arrive at breeding areas at the optimal time to set up nesting territories and exploit seasonally abundant food resources, and because climate change has the potential to occur more rapidly than …

Making Soap Green, Asia Sweet Apr 2018

Making Soap Green, Asia Sweet

Thinking Matters Symposium Archive

The One Gallon Soap Company (OGSC) recycles partially used bar soap from local Portland hotels and repurposes it as liquid hand soap. The preliminary formulations originally prepared by the OGSC produced a smooth, homogeneous liquid soap with good foaming action. However, over short and often variable time periods, the soap would separate into two layers: a watery bottom layer with little foaming action and an oily top layer. The OGSC asked the USM Chemistry Department to investigate the formulation process in an effort to provide a more stable product – one that would maintain a constant consistency over several months.
