Can We Use Gamification to Predict Students’ Performance? A Case Study Supported by an Online Judge (2020)
Presentation / Conference Contribution

The impact of gamification has been typically evaluated via self-report assessments (questionnaires, surveys, etc.). In this work, we analise the use of gamification elements as parameters, to predict whether students are going to fail or not in a pr...

Only the largest terrestrial Carnivores increase their dietary breadth with increasing prey richness (2020)
Journal Article

1. Animals should adapt their foraging habits, changing their dietary breadth in response to variation in the richness and availability of food resources. Understanding how species modify their dietary breadth according to variation in resource richn...

Using learning analytics in the Amazonas: understanding students’ behaviour in introductory programming (2020)
Journal Article

Tools for automatic grading programming assignments, also known as Online Judges, have been widely used to support computer science (CS) courses. Nevertheless, few studies have used these tools to acquire and analyse interaction data to better unders...

$C^*$-algebras of right LCM monoids and their equilibrium states (2020)
Journal Article

We study the internal structure of C-algebras of right LCM monoids by means of isolating the core semigroup C-algebra as the coecient algebra of a Fock-type module on which the full semigroup C-algebra admits a left action. If the semigroup has a gen... Read More about $C^*$-algebras of right LCM monoids and their equilibrium states.

Splitting of two-component solitary waves from collisions with narrow potential barriers (2020)
Journal Article

We consider the interaction of two-component bright-bright solitons with a narrow potential barrier (splitter) in the framework of a system of two Gross-Pitaevskii (nonlinear-Schrödinger) equations modeling a binary Bose-Einstein condensate, with sel...

Citizen scientists: school students conducting, contributing to and communicating ecological research – experiences of a school–university partnership (2020)
Journal Article

Started in north-east England in 2015, MammalWeb aims to improve our knowledge of British mammals through the use of motion-sensing camera traps. Fundamental to the project is the involvement of local communities and individuals who act as citizen sc...

Burning savanna for avian species richness and functional diversity (2020)
Journal Article

Prescribed fire is used throughout fire‐prone landscapes to conserve biodiversity. Current best practice in managing savanna systems advocates methods based on the assumption that increased fire‐mediated landscape heterogeneity (pyrodiversity) will p...

Best practice for collar deployment of tri-axial accelerometers on a terrestrial quadruped to provide accurate measurement of body acceleration (2020)
Journal Article

Background: Tri-axial accelerometers are frequently deployed on terrestrial quadrupedal mammals using collars, because they are easy to fit and are thought to have minimal impact on the subject. Collar-attached devices are not fixed to the body and c... Read More about Best practice for collar deployment of tri-axial accelerometers on a terrestrial quadruped to provide accurate measurement of body acceleration.

Splitting and recombination of bright-solitary-matter waves (2020)
Journal Article

Atomic Bose–Einstein condensates confined in quasi-1D waveguides can support bright-solitary-matter waves when interatomic interactions are sufficiently attractive to cancel dispersion. Such solitary-matter waves are excellent candidates for highly s... Read More about Splitting and recombination of bright-solitary-matter waves.

A global assessment of the drivers of threatened terrestrial species richness (2020)
Journal Article

High numbers of threatened species might be expected to occur where overall species richness is also high; however, this explains only a proportion of the global variation in threatened species richness. Understanding why many areas have more or fewe... Read More about A global assessment of the drivers of threatened terrestrial species richness.

Evaluating the operational resilience of small and medium-sized enterprises to flooding using a computational modelling and simulation approach: a case study of the 2007 flood in Tewkesbury (2020)
Journal Article

The resilience of small and medium-sized enterprises (SMEs) to disruptive events is significant as this highly prevalent category of business forms the economic backbone in developed countries. This article provides an overview of the application of...

Multiple scattering in scanning helium microscopy (2020)
Journal Article

Using atom beams to image the surface of samples in real space is an emerging technique that delivers unique contrast from delicate samples. Here, we explore the contrast that arises from multiple scattering of helium atoms, a specific process that p... Read More about Multiple scattering in scanning helium microscopy.

Spin–orbit coupling in the presence of strong atomic correlations (2020)
Journal Article

We explore the influence of contact interactions on a synthetically spin–orbit coupled system of two ultracold trapped atoms. Even though the system we consider is bosonic, we show that a regime exists in which the competition between the contact and...
