SARS-CoV-2 continues to widely circulate in populations globally. Underdetection is acknowledged and is problematic when attempting to capture the true prevalence. Seroprevalence studies, where blood samples from a population sample are tested for SARS-CoV-2 antibodies that react to the SARS-CoV-2 virus, are a common method for estimating the propo...

It has long been established that pupillary responses provide a valid and reliable window on the “intensity” of mental activity or cognitive effort (Hess & Polt, 1964; Kahneman & Beatty, 1966). As these responses are routinely and noninvasively measured during eye-tracking, they constitute a promising tool for the study of the cognitive mechanisms...
Article
Dance is an extremely popular activity among adolescents and has a range of associated physical and psychological health benefits. However, pain and injury in young elite dancers is pervasive, and the underlying risk factors are poorly understood. This study investigated the incidence of pain and injury in elite adolescent Irish dancers and examine...

The proliferation of new biomechanical technology in laboratory and field settings facilitates the capture of data-sets consisting of complex time-series. An understanding of the appropriate statistical approaches for analysing and interpreting these data-sets is required and the functional data analysis (FDA) family of statistical techniques has e...
Article
Sporting performance is often investigated through graphical observation of key technical variables that are representative of whole movements. The presence of differences between athletes in such variables has led to terms such as movement signatures being used. These signatures can be multivariate (multiple time-series observed concurrently), and...

Objectives: To examine whether gender or side of the boat influenced shape characteristics of the force-angle profile in on-water single sculling. Design: Cross-sectional study design. Methods: Bivariate functional principal components analysis (bfPCA) was applied to force-angle data to identify the main modes of variance in curves of forty hi...
Article
Aim: Although the relationships between duration of untreated psychosis (DUP) and outcomes are often assumed to be linear, few studies have explored the functional form of these relationships. The aim of this study is to demonstrate the potential of recent advances in curve fitting approaches (splines) to explore the form of the relationship betwe...
Article
In recent decades, magnetic susceptibility monitoring has developed as a useful technique in environmental pollution studies, particularly metal contamination of soil. This study provides the first ever examination of the effects of grass cover on magnetic susceptibility (MS) measurements of underlying urban soils. Magnetic measurements were taken...
Article
The graphical presentation of the propulsive force applied at the pin plotted relative to the horizontal angle of the oar has been used practically in on-water rowing for the qualitative assessment of skill. How the pattern is related to performance variables has not been well identified, particularly for highly trained sculling athletes. Bivariate...
Article
The presence of arsenic in groundwater has become a global concern due to the health risks from drinking water with elevated concentrations. The Water Framework Directive (WFD) of the European Union calls for drinking water risk assessment for member states. The present study amalgamates readily available national and sub-national scale datasets on...
Article
Previous research in Irish dancing (ID) has recorded high levels of pain/injury. Screening protocols in other genres have been developed to identify at-risk dancers. The aims of the study were to examine the factors that relate to absence from dancing because of musculo-skeletal pain/injury in ID, and to inform guidelines for the development of an...
Conference Paper
The pattern of propulsive force (measured at the pin), represented by force-time and force-angle graphs, typically differs among rowers. How the pattern differs according to competition level and gender has not been identified. Functional data analysis (FDA) techniques were used on force-time and force-angle data to identify the main modes of varia...

Non-specific chronic low back pain (NSCLBP) is a very common and costly musculoskeletal disorder associated with a complex interplay of biopsychosocial factors. Cognitive functional therapy (CFT) represents a novel, patient-centred intervention which directly challenges pain-related behaviours in a cognitively integrated, functionally specific and...

Finite mixture models have been used extensively in clustering applications, where each component of the mixture distribution is assumed to represent an individual cluster. The simplest example describes each cluster in terms of a multivariate Gaussian density with various covariance structures. However, using finite mixture models as a clustering...

Longitudinal data is becoming increasingly common and various methods have been developed to analyze this type of data. Profiles from time-course gene expression studies, where cluster analysis plays an important role to identify groups of co-expressed genes over time, are investigated. A number of procedures have been used to cluster time-course g...

Gene expression over time can be viewed as a continuous process and therefore represented as a continuous curve or function. Functional data analysis (FDA) is a statistical methodology used to analyze functional data that has become increasingly popular in the analysis of time-course gene expression data. Several FDA techniques have been applied to...
Article
Chronic Achilles tendon (AT) injuries are common, but kinematic studies confirming the exact mechanisms of injury and how orthoses are effective are lacking. Existing analysis often relies on discrete measures and provides an incomplete analysis because many of the data are discarded. Functional data analysis (FDA) views the entire dataset as a fun...
Article
This paper examines the pitfalls that arise when an outlier is assessed using a criterion based on a fixed multiple of the standard deviation rather than an established statistical test. Although the former approach is statistically invalid, it is the favored method for identifying outliers in Ontario laboratory quality control protocols. Computer...

The objective of GOGREEN ROUTES is to position European cities as world ambassadors of urban sustainability. Our inspirational approach shifts the focus of NBS towards the co-benefits to multidimensional health-termed 360-Health. GOGREEN ROUTES transdisciplinary consortium will pioneer a unique approach augmenting NBS, urban design with the goal of fostering a positive human-nature relationship, flourishing nature connectedness and promoting citizen engagement through digital, educational and behavioural innovation. GOGREEN ROUTES components focus on nature-based enterprise (GROW), sustainable physical activity (MOVE), digital, cultural (FEEL) and knowledge innovation (KNOW). GOGREEN ROUTES fosters mental health and well-being by optimising human-nature interactions for all citizens. These innovations will increase the uptake and acceptability of NBS across “Cultivating Cities” (Burgas, Lahti, Limerick, Tallinn, Umea & Versailles), “Seed Cities” (Munich, Murcia region & Malta) and a “Cross-Pollination Network: (Beijing, Mexico, & Tblisi). An urban well-being lab, based on the living lab methodology will couple participatory approaches with the Big Data analyses. To advance knowledge, best practice and dissemination GOGREEN ROUTES will cluster with H2020 projects including those involving our partners (e.g. proGIreg, bluehealth2020, Connecting Nature). In addition, linking all open-sourced data to the OPPLA and Think Nature Hubs, delivering online resource (e.g. Urban 360-Health Toolkit, MOOC’s) and empowering citizens in an iterative process of co-creation will ensure perpetuation beyond the end of the project. This novel approach, coupled with the high capacity of the consortium, makes GOGREEN ROUTES an exciting prospect. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 869764.
Project
Mental health in sport remains a serious issue which merits an action plan to ensure sport environments are well-being promoting and that athletes, coaches, sport science support and other entourage members all win through well-being. Direct attempts to tackle mental health may have unintended consequences including increasing stigma through labeling and reducing help-seeking behaviors. We propose a series of innovative novel solutions which are evidence-based. To this end our initial studies focus on assessing knowledge of mental health and attitudes towards help seeking among various stakeholders. We use case study scenarios in addition to standardized inventories in our research.
