Petsakos, Athanasios; Hareau, Guy; Kleinwechter, Ulrich; Wiebe, Keith; Sulser, Timothy B. – Research Evaluation, 2018
This article examines how the estimated impacts of crop technologies vary with alternate methods and assumptions, and also discusses the implications of these differences for the design of studies to inform research prioritization. Drawing on international potato research, we show how foresight scenarios, realized by a multi-period global…

Courtney, Michael; Courtney, Amy – Physics Teacher, 2007
Potato cannon velocity can be measured with a digitized microphone signal. A microphone is attached to the potato cannon muzzle, and a potato is fired at an aluminum target about 10 m away. Flight time can be determined from the acoustic waveform by subtracting the time in the barrel and time for sound to return from the target. The potato…

Sigurdsson, Valdimar; Saevarsson, Hugi; Foxall, Gordon – Journal of Applied Behavior Analysis, 2009
An in-store experiment was performed to investigate the effects of shelf placement (high, middle, low) on consumers' purchases of potato chips. Placement of potato chips on the middle shelf was associated with the highest percentage of purchases. The results confirm the importance of item placement as a factor in consumers' buying behavior.…

Sharma, R. K.; Yadav, Subham; Gupta, Radhika; Arora, Gunjan – Journal of Chemical Education, 2019
Systems thinking is highly desirable for re-imagining chemistry education, which will help in the development of an integrated and sustainable approach that takes into account the interdependence of a system under study with other components of the ecosystem rather than practicing a fragmented approach. Thus, to develop a systems' perspective into…

Arciuli, Joanne; Bailey, Benjamin – Journal of Child Language, 2019
In this exploratory study, we examined stress contrastivity within real word productions elicited via picture naming in 20 children with autism spectrum disorders (ASD) and 20 typical peers group-wise matched on age and vocabulary. Targets had a dominant pattern of lexical stress beginning with a strong-weak pattern (SW: 'caterpillar',…

Sakarias, Maria; Flecken, Monique – Cognitive Science, 2019
We study how people attend to and memorize endings of events that differ in the degree to which objects in them are affected by an action: "Resultative" events show objects that undergo a visually salient change in state during the course of the event (peeling a potato), and "non-resultative" events involve objects that undergo…

Dias, Alice M.; Ferreira, Maria La Salete – Journal of Chemical Education, 2015
A simple and ecofriendly procedure was developed in order to prepare extracts from red and green leaves. This procedure enables the separation of yellow, green, and red band pigments and optimizes the previously reported baking soda "supermarket column". The same extract also led to a novel and colorful potato starch column, which can…

Ortiz Lechuga, Eugenia Guadalupe; Tovar Herrera, Omar Eduardo; Arévalo Niño, Katiushka – Biochemistry and Molecular Biology Education, 2019
In this work, we present the results of an undergrad student from the perspective of its first approach as a principal researcher in a project. In order to gain practical experience, one of the options for students that have interest in pursuing a postgraduate program corresponds to a research stay in a laboratory of their selected field…

Bristow, Kelly; Jenkins, Steven; Kelly, Patrick; Mattfeldt-Beman, Mildred – Journal of Child Nutrition & Management, 2017
Purpose/Objectives: Schools are offering more fruits and vegetables; yet consumption of fruits and vegetables among adolescents remains low. Many schools are implementing Farm-to-School programs to help generate excitement and increase selection of fruits and vegetables by students. The purpose of this research was to determine if a simple tasting…
