Towards an understanding of job matching using web data

The thesis explores the feasibility of using web data in labour research in general and of applying these data sources to the study of job matching in particular. Utilizing large-scale data sources, including web surveys and online job vacancies, the thesis aims to identify where the state of the art is and lay methodological, conceptual and analytical foundations for further exploration and research in the area. Formally, the thesis consists of five essays, which either have been or are on the way to be published in scientific journals

The Ethical and Political Contours of Institutional Promotion in Esports : From Precariat Models to Sustainable Practices

This study evaluated five early cases in which esport developer Riot Games made rulings regarding activities and infractions by members of various institutions related to its product, League of Legends. The findings of this study support future theoretical exploration of other esports in seeking a fuller understanding of issues related to consent, power differentials, and roles and behaviors expected of the institutional activities of players and teams in competition. Increased investigation of these—and other—issues from an ethical standpoint could lead to a framework that not only would facilitate future study but also bring opportunities for improvements in practices in concert with necessary policy changes.</p

Healthy Competition: Multiplayer Digital Games in Health Education

The focus of this dissertation is on the role of multiplayer digital games in adult education, with a particular emphasis on health education. Although interest in the use of digital games for serious applications has been increasing since the early 2000s, there is a significant gap in understanding on the use of multiplayer digital games in adult education. In the context of health education, there has been a large amount of research conducted in to the use of repurposed commercial games for predicting performance of trainees and health students on surgical simulators. However, beyond this niche research into game based learning is notably less cohesive. There has been some research into the use of digital games in areas such as for delivering insulin management training, but understanding of the processes for widespread application of games based learning in the health sector is limited. Additionally, almost no research has been undertaken into the use of multiplayer digital games in health education, whether it be for tertiary or adult learners. In this dissertation two digital games were developed, implemented and evaluated to explore the value of multiplayer games for supporting cooperation and collaboration in health education. The first game, They Know: Anatomy, was a real time team based strategy game designed to support anatomy revision by second year medical students. The second game, the Qstream: Cancer Cup Challenge, was a team based asynchronous online program designed to reinforce understanding of how to identify and manage adverse events by oncology registrars. A design research framework informed the methodology used in this dissertation. This framework emphasises the need to use multiple iteration cycles to develop a comprehensive understanding of player experiences with the digital games they encountered. Data on participant experiences with the digital games was collected using qualitative methods, including post-game surveys and semi-structured interviews. Between iterative cycles data on participant experiences with the digital games were analysed so that future implementations of the game could be modified to maximise cooperation and collaboration between players. At the conclusion of the study period data collected across all implementations of the digital games were analysed to increase understanding of how multiplayer digital games supported cooperation and collaboration between learners. Findings from this dissertation demonstrate that multiplayer digital games can be used to engage medical students in anatomy revision and medical oncologists in adverse events retraining. This is the first study to look at the use of digital games for either of these demographics. Additionally, this dissertation identified four ways through which multiplayer digital games foster collaboration between players: through the development of a team strategy to win the game, by facilitating !iii shared decision making, by working towards a shared goal, and by creating a sense of investment in a team. Finally, findings from this dissertation contribute to the literature on the implementation of game based learning in adult education. This is an under researched area, but one that warrants further focus in future if game based learning is going to be successfully incorporated into curricula and training activities for adult learners. This dissertation adds to the literature by presenting new knowledge on how and why multiplayer games support collaboration between learners. Additionally, it appears that multiplayer digital games offer diverse, flexible and immersive experiences to adult learners in a way that single player digital games may not. Finally, multiplayer digital games provide new avenues for support self-directed learning by encouraging cooperation between large groups of students in a manner that is not normally achieved in online learning environment

Neurobiological correlates of avatar identification processing and emotional inhibitory control in internet gaming disorder

Internet gaming disorder (IGD) is the most prevalent subcategory of internet addiction. It has been associated with self-concept deficits and related characteristics such as emotional as well as social competence deficits, increased social anxiety and a stronger identification with the own avatar (i.e. a graphical agent that often seems to be constructed according to gamers’ ideal). In addition, IGD seems to be linked with inhibitory control deficits, definable as impairments in the inhibition of reactions to irrelevant stimuli during the pursuit of cognitively represented goals. However, the neurobiological correlates of avatar compared to self and ideal-related identification processing as well as emotional inhibitory control in (socially) anxious contexts as potentially important factors in IGD development have not been explored yet. The brain region of the left angular gyrus (AG) has been associated with self-identification from a third-person perspective in healthy controls and showed avatar-related hyperactivation in long-term online gamers during a task on self and avatar reflection in functional magnetic resonance imaging (fMRI). The dorsal anterior cingulate cortex (dACC) seems to be involved in the integration of negative affect and cognitive control. Based on these observations, internet gaming addicts were neurobiologically examined by means of fMRI with a focus on the left AG as well as the dACC while completing specific tasks and compared to non-addicted controls as well as social media addicts. Hereby, participants’ concepts of self, ideal and avatar were assessed with a reflection task asking for the evaluation of characteristics regarding the self, ideal and own avatar. Emotional inhibitory control in a socially anxious context was neurobiologically explored by means of an emotional Stroop task (EST) assessing the inhibition on socially anxious words compared to positive, negative and neutral word stimuli under parallel reaction time recording. In addition, the emotional inhibitory control at anxious stimuli was examined neuropsychologically by means of an affective Go/No-Go task (AGN). Besides, psychometric questionnaires assessing impulsivity, emotional competence and social anxiety were applied. Internet gaming addicts showed significantly higher levels of impulsivity, social anxiety and emotional competence deficits relative to non-addicted controls in psychometric measures. Neurobiologically, internet gaming addicts exhibited left AG hyperactivations during the reflection on their own avatar relative to self and ideal reflection within their group as well as compared to non-addicted controls. In the EST, internet gaming addicts had longer reaction times during the inhibition on socially anxious compared to positive and negative words as well as compared to positive, negative and neutral words together. During the latter comparison, internet gaming addicts neurobiologically showed significant hypoactivations in the left middle and superior temporal gyrus (MTG and STG), which was also significantly lower relative to social media addicts. Functional alterations in the dACC were not observed. Neuropsychologically, no significant differences in emotional inhibitory control at anxious stimuli between internet gaming addicts and non-addicted controls were detected by means of the AGN. In summary, the virtually concretized avatar might replace the rather abstract ideal in IGD as a construct to identify with. The need for such a construct might arise from the urge to compensate dissatisfaction with the own person as a facet of self-concept deficits. The MTG and STG have previously been associated with the retrieval of words or expressions during communication, social perception and emotion regulation (based on a study in social anxiety disorder). The present finding of these regions’ hypoactivation in relation to socially anxious stimuli might indicate that 1) socially anxious words are less retrievable from the semantic storage of internet gaming addicts than positive, negative or neutral words, 2) in IGD, emotional inhibitory control in the socially anxious context is represented by brain regions involved in the processing of social information (such as the MTG and STG) and that 3) internet gaming addicts have deficiencies in the cognitive regulation of emotions as well as in the processing of social information, with the MTG and STG hypoactivation during socially anxious word blocks possibly serving as a neurobiological correlate of IGD-related social and emotional competence deficits as facets of self-concept impairments

Social Presence in Team-Based Digital Games

This thesis explores the concept of social presence in team-based digital games, aiming to enlighten the core elements of social presence in this specific multi-user experience. The thesis achieves this exploration in three main ways, by using a novel approach to establish the core elements of social presence in team-based digital games, by developing a new measure for social presence specifically tailored for team-based digital games, and by exploring the effects of contextual gameplay factors on social presence in a large scale user study. The thesis documents the work carried out over the course of an Engineering Doctorate (EngD) sponsored by BAE Systems, who gave an industry perspective, helped to set the direction of the research and guide it throughout the program. The industry relevance to studying social presence in team-based digital games was the analogous nature of teambased games to virtual training technologies such as simulators and serious games, and the lack of understanding of social elements within these technologies. The research questions for this thesis were as follows: What is the nature of social presence in team-based digital games? How social presence is affected by sharing a team-based virtual environment with human or computer controlled entities? What other contextual elements encourage or reduce feelings of social presence? The first set of studies detailed in this thesis were a preliminary exploration of social presence in team-based digital games, a group of short user studies termed experiential vignettes, investigating the effect of agency on user experience. The experiential vignettes suggest that social presence is affected by a player’s perception of the other entities in the virtual environment, however the extent of the affect is highly dependent on task. These preliminary studies led to the development of a questionnaire designed to measure social presence in team-based digital games, the competitive and cooperative social presence questionnaire (CCPIG), developed and validated using user studies. The CCPIG was utilized and further validated in a large scale user study which aimed to explore the conceptual crossover between team trust and social presence, and how various contextual variables affected these concepts. This thesis shows that competitive and cooperative social presence are two distinct concepts, and that there is significant conceptual crossover between social presence and established notions of team trust. This thesis also shows that social presence is highly context dependent, affected by agency, familiarity with other players, team performance, and the nature of the game in which the experience occurs
