The Plymouth Student Scientist - Volume 14, No.1 - 2021
Table of contents
A notable mention - All these incredible research and development articles in this edition are from STEM students at the University of Plymouth, working on their final year research project during the COVID19 lockdowns of 2020 and 2021. A huge thank you to them, and their committed supervisors in STEM. I have enjoyed reading your submissions and working with you all. Not only have you navigated nimbly the COVID19 restrictions, but also tackled the conversion and review process to produce these excellent papers! I very much hope that the experience of being "published" takes you to greater heights in your future careers. Feel free to share your success and cite your work. With kind regards, Dr Jason B. Truscott (Chief Editor).

Codeo - Learning support research: use of automated feedback within undergraduate programming education, a case study (University of Plymouth, 2021)This paper describes the research process of a case study in the domain of pedagogical computer science, specifically in the context of how first year undergraduate students learn programming skills, with the purpose of ...
The relationship between sociodemographic factors and the snacking and drinking behaviours of children aged between 1 and 5 years in early years settings across Plymouth (University of Plymouth, 2021)Sugar consumption amongst children continues to sit above the current UK recommendations, contributing to rates of obesity and dental caries in this group. Previous research has focused on children of school age, investigating ...
Acute stress, friend or foe: An investigation of free recall ability for incongruent items when placed under acute psychological stress (University of Plymouth, 2021)Experiencing stress during a working week is typical for most of the population, but the effects of acute stress on individuals is less clear cut, particularly in relation to memory ability. Research suggests that acute ...
The effect of chlorhexidine mouthwash vs propolis mouthwash on the nitrate-reducing activity of oral bacteria and vascular control in healthy individuals (University of Plymouth, 2021)Nitrate and nitrite molecules are involved in the synthesis of nitric oxide (NO), a gaseous vasodilatory molecule, via the nitrate-nitrite-NO pathway. Oral bacteria are responsible for the reduction of nitrate to nitrite ...
(University of Plymouth, 2021)Medium carbon steel 070M55, also known as EN9 or AISI/SAE 1055, was heat treated with five different heat treatment procedures to promote varying microstructures resulting in enhanced properties of the metal. The aim of ...
Producing a theoretical model for determining the appropriate propeller for a given model aircraft application (University of Plymouth, 2021)This paper investigates a method of determining the most suitable propeller for any given model aircraft application based on simple inputs such as desired airspeed and powerplant requirements. This method has been embodied ...
(University of Plymouth, 2021)For this paper, a simple inexpensive rig system was designed and two methods for imaging and measuring how a synthetic representation of an anastomosed artery deforms under internal pressure were used. An optical method ...
A qualitative investigation of media framing regarding Christopher Jefferies in the case of Joanna Yeates’ murder (University of Plymouth, 2021)Framing describes the process of how things are constructed and perceived through communication. Media framing refers to how things are presented when relaying information to others. Many framing techniques are used to ...
Negative emotional appeals: The effectiveness of fear and guilt communicative appeals on individuals pro-environmental behaviour and environmental concern to microplastic pollution (University of Plymouth, 2021)In an ever-growing ‘throwaway’ society, the world’s oceans are coming under new and persistent pressures from anthropogenic activity. Marine plastic pollution is caused exclusively by human behaviours and decisions. ...
(University of Plymouth, 2021)Current literature is claiming for an important relationship between conscious experiencing and executive functions (mainly working memory). Since there is still a lack of empirical evidence relating those mental processes, ...
