Item Restricted Modelling Emergency Attendances and Waiting Times in Scotland(The University of Edinburgh, 2024-07) Alkathiri, Shaymaa; Wood, SimonBackground and Aims: Emergency Departments (EDs) in Scotland face significant challenges due to fluctuating patient loads and increased waiting times in recent years. This research aims to analyse and predict total attendances and waiting times in Emergency Departments in Scotland. The purpose is to offer insightful analysis, modelling, and predictions to Public Health Scotland, enhancing the efficiency of emergency healthcare services. Data: The analysis is based on two datasets provided by Public Health Scotland: the monthly statistics dataset and the weekly statistics dataset. Method: We developed four Generalized Additive Models (GAMs) to predict the two main outcomes: the number of attendances in Emergency Departments and the number of attendances categorized by waiting times (within 4 hours and over 4 hours). GAMs were chosen for their ability to model complex, non-linear relationships effectively by incorporating temporal and geographical factors.19 0Item Restricted The Effect of Previous Qualifications on Students’ Study Behaviours and Outcomes(Saudi Digital Library, 2023) Alfurayh, Sarah Nasser; Woods, GarethThis study explores how highest qualification on university entry and factors like ethnicity, gender, and socio-economic class influence academic performance at Aston University over two academic years (2021/22 and 2022/23). Using data from Aston University, we found that Black students’ diagnostic scores varied across the years, and students with A/AS-level qualifications generally did better than others. Socio-economic factors played a role, especially in the 2022/23 year, and gender differences were evident in 2022/23. We also studied the role of Peer-Assisted Learning (PAL) sessions. We found that more PAL attendance is linked to better final scores. Some modules benefited more from PAL sessions than others, showing the complex links between PAL, ethnicity, and highest qualification on entry. The findings highlight the need for ongoing evaluation and tailored support, especially for underrepresented students.14 0Item Restricted AN EXPERIMENTAL INVESTIGATION OF BRADLEY-TERRY MODEL TO MEASURE ITS PERFORMANCE(2020-01-01) Aljuhani, Yasmina Mohammad; Gillard, JonathanIn pairwise comparison, the items being compared are judged in pairs to see which of the two is preferred. Many statistical techniques have emerged over the past decades which concern the methods of analysing pairwise comparisons. One of the most popular statistical models is the Bradley–Terry model, which was developed with a view to analysing the results from a set of paired comparisons. This model is widely employed to calculate the probabilities by making repeated pairwise comparisons between the items when no real measurement is possible. Bradley-Terry model has evolved over time and used in different applications such as ranking of sports team. Different extensions of the Bradley-Terry model have been proposed to overcome some existing limitation of the model.27 0
