The temporal explorer who returns to the base
Presentation / Conference Contribution
Akrida, E., Mertzios, G., & Spirakis, P. (2019, December). The temporal explorer who returns to the base. Presented at 11th International Conference on Algorithms and Complexity (CIAC 2019), Rome, Italy

In this paper we study the problem of exploring a temporal graph (i.e. a graph that changes over time), in the fundamental case where the underlying static graph is a star on n vertices. The aim of the exploration problem in a temporal star is to fin... Read More about The temporal explorer who returns to the base.

An Exploration of Dropout with RNNs for Natural Language Inference
Presentation / Conference Contribution
Gajbhiye, A., Jaf, S., Al-Moubayed, N., McGough, A. S., & Bradley, S. (2018, December). An Exploration of Dropout with RNNs for Natural Language Inference. Presented at ICANN 2018: 27th International Conference on Artificial Neural Networks, Rhodes

Dropout is a crucial regularization technique for the Recurrent Neural Network (RNN) models of Natural Language Inference (NLI). However, dropout has not been evaluated for the effectiveness at different layers and dropout rates in NLI models. In thi...

Managing Plagiarism in Programming Assignments with Blended Assessment and Randomisation
Presentation / Conference Contribution
Bradley, S. (2016, November). Managing Plagiarism in Programming Assignments with Blended Assessment and Randomisation. Presented at 16th Koli Calling Conference on Computing Education Research, Koli, Finland

Plagiarism is a common concern for coursework in many situations, particularly where electronic solutions can be provided e.g. computer programs, and leads to unreliability of assessment. Written exams are often used to try to deal with this, and to... Read More about Managing Plagiarism in Programming Assignments with Blended Assessment and Randomisation.

On temporally connected graphs of small cost
Presentation / Conference Contribution
Akrida, E., Gasieniec, L., Mertzios, G., & Spirakis, P. (2015, September). On temporally connected graphs of small cost. Presented at 13th Workshop on Approximation and Online Algorithms (WAOA), Patras, Greece

We study the design of small cost temporally connected graphs, under various constraints. We mainly consider undirected graphs of n vertices, where each edge has an associated set of discrete availability instances (labels). A journey from vertex u t...

Ephemeral networks with random availability of links: diameter and connectivity
Presentation / Conference Contribution
Akrida, E., Gasieniec, L., Mertzios, G., & Spirakis, P. (2014, June). Ephemeral networks with random availability of links: diameter and connectivity. Presented at Proceedings of the 26th ACM symposium on Parallelism in algorithms and architectures (SPAA), Prague, Czech Republic

In this work we consider temporal networks, the links of which are available only at random times (randomly available temporal networks). Our networks are {\em ephemeral}: their links appear sporadically, only at certain times, within a given maximum...

Evidence for Teaching Practices that Broaden Participation for Women in Computing
Presentation / Conference Contribution
Morrison, B. B., Quinn, B. A., Bradley, S., Buffardi, K., Harrington, B., Hu, H. H., Kallia, M., McNeill, F., Ola, O., Parker, M., Rosato, J., & Waite, J. (2021, December). Evidence for Teaching Practices that Broaden Participation for Women in Computing. Presented at Proceedings of the 2021 Working Group Reports on Innovation and Technology in Computer Science Education

Computing has, for many years, been one of the least demographically diverse STEM fields, particularly in terms of women's participation [12, 36]. The last decade has seen a proliferation of research exploring new teaching techniques and their effect...

Narrowing and Stretching: Addressing the Challenge of Multi-track Programming
Presentation / Conference Contribution
Bradley, S., & Akrida, E. (2022, December). Narrowing and Stretching: Addressing the Challenge of Multi-track Programming. Presented at Computing Education Practice 2022, Durham, England

Given the different amount of programming experience that students have arriving at university, some universities have introduced alternative multiple streams to teach programming. This approach was exemplified by Harvey Mudd College, who successfull... Read More about Narrowing and Stretching: Addressing the Challenge of Multi-track Programming.

GamiCSM: relating education, culture and gamification - a link between worlds
Presentation / Conference Contribution
Toda, A., Klock, A. C. T., Palomino, P. T., Rodrigues, L., Oliveira, W., Stewart, C., Cristea, A. I., Gasparini, I., & Isotani, S. (2020, October). GamiCSM: relating education, culture and gamification - a link between worlds. Presented at 19th Brazilian Symposium on Human Factors in Computing Systems, Diamantina, Brazil

The potential of gamification to improve users' motivation and engagement influenced many researchers and professionals to analyse its effects in educational settings. While some studies focus on adapting game elements according to demographic and be... Read More about GamiCSM: relating education, culture and gamification - a link between worlds.

Student Perceptions of Assessment and Feedback - are they valid?
Presentation / Conference Contribution
Crosby, R. (2021, January). Student Perceptions of Assessment and Feedback - are they valid?. Presented at CEP '21: Computing Education Practice 2021, Durham, UK

Although good assessment and feedback practices are widely recognised as crucial to learning, historical UK NSS results illustrate that current practices leave students dissatisfied the most in terms of their overall learning experience. This paper o... Read More about Student Perceptions of Assessment and Feedback - are they valid?.

Temporal Flows in Temporal Networks
Presentation / Conference Contribution

We introduce temporal flows on temporal networks [17, 19], i.e., networks the links of which exist only at certain moments of time. Such networks are ephemeral in the sense that no link exists after some time. Our flow model is new and differs from t... Read More about Temporal Flows in Temporal Networks.

On Verifying and Maintaining Connectivity of Interval Temporal Networks
Presentation / Conference Contribution
Akrida, E. C., & Spirakis, P. G. (2015, December). On Verifying and Maintaining Connectivity of Interval Temporal Networks. Presented at Algorithmic Aspects of Wireless Sensor Networks (ALGOSENSORS), Patras, Greece

An interval temporal network is, informally speaking, a network whose links change with time. The term interval means that a link may exist for one or more time intervals, called availability intervals of the link, after which it does not exist (unti...

Creative Assessment in Programming: Diversity and Divergence
Presentation / Conference Contribution
Bradley, S. (2020, January). Creative Assessment in Programming: Diversity and Divergence. Presented at Proceedings of the 4th Conference on Computing Education Practice 2020, Durham, England

Negative stereotypes persist in computing, and align poorly with research into the motivations of female students. In particular, female students are more inclined to want to work creatively and have a positive impact through their work. However prog...
