Turning Users' In-Game Behaviours into Actionable Adaptive Gamification Strategies using the PEAS Framework

Adaptive gamification answers the need to customize engagement strategies because users are motivated by different game elements and mechanics. To better understand these individual preferences, user modelling is vital. However, gameful designers must make many decisions on matching profiling data to actual adaptation strategies, which makes modelling particularly challenging. The lack of a standardized and guided process for adaptive gamification hinders replicability, comparability, and complicates making adaptation dynamic. In this study, we analyzed a persuasive gameful application (Play\&Go) to show how in-game behaviours can be translated into adaptation strategies. We used an existing adaptation framework (PEAS) grounded in the games and gamification literature. Our work demonstrates the suitability of the PEAS model as a shared, standardized method for adaptive gamification and shows how it can guide the process of transforming user behaviours into actionable adaptation strategies

AtDelfi: Automatically Designing Legible, Full Instructions For Games

This paper introduces a fully automatic method for generating video game tutorials. The AtDELFI system (AuTomatically DEsigning Legible, Full Instructions for games) was created to investigate procedural generation of instructions that teach players how to play video games. We present a representation of game rules and mechanics using a graph system as well as a tutorial generation method that uses said graph representation. We demonstrate the concept by testing it on games within the General Video Game Artificial Intelligence (GVG-AI) framework; the paper discusses tutorials generated for eight different games. Our findings suggest that a graph representation scheme works well for simple arcade style games such as Space Invaders and Pacman, but it appears that tutorials for more complex games might require higher-level understanding of the game than just single mechanics.Comment: 10 pages, 11 figures, published at Foundations of Digital Games Conference 201

Exporting Kenya's Horticultural Products: Challenges and Opportunities in The 21st Century

The horticultural export sector has experienced rapid growth since 1966 because of the active role by the private sector and minimum government intervention. The European Union is the largest consumer of Kenyan horticultural exports. Kenyan horticultural exports to the European Union accounted for 45 percent of the total exports in 2000. In recent years, horticultural export growth has declined. The quality of production has declined, following a reduction of the role of exporters in supporting production by small-scale farmers. This has reduced Kenyas competitiveness in the horticultural export market at time when the sector is faced with increased competition from other producer countries. The reform of the European Union Common Agricultural Policy (CAP) and other emerging issues in the on-going negotiations on the Agreement on Agriculture (AOA) at the World Trade Organization (WTO) present other pertinent issues as concerns expanded export horticulture. This paper, firstly, reviews the performance of the export horticulture over the last four decades, it delineates challenges facing export horticulture, it highlights opportunities available for expanded export horticulture and suggests measures for revitalizing the sub-sector. It concludes that, competition for the EU market will continue to intensify as the world opens up due to globalization. This calls for proper understanding of the existing and emerging threats to the Kenyan export horticulture. This will guide the development of both defensive and offensive strategies for not only survival in the EU market, but also venturing in non-traditional horticultural export markets. Such strategies would include (i) Education of producers to understand the EU import requirements which encompass both tariff and non-tariff measures, (ii) penetration of new markets in Asia, USA, and Africa,(iii) encouragement of organic farming where necessary, and (iv) creating an enabling environment for small scale farmers to access credit.Kenya, Export Horticulture, Challenges, Opportunities, Crop Production/Industries,

The Parched Earth of Cooperation: How to Solve the Tragedy of the Commons in International Environmental Governance

This article proposes a way to strengthen international environmental agreements, such as the Paris Agreement and the Kyoto Protocol. Multilateral environmental agreements such as these are extremely fragile. At the heart of the problem is what is known as the tragedy of the commons—a unique dynamic that viciously sabotages cooperation. The cause of this tragedy is that no one can trust that other actors will conserve the common resource, which triggers a race to the bottom—a race to deplete. Global warming and our inability to halt it is perhaps the ultimate example of a tragedy of the commons on a truly massive scale. On a domestic level, the tragedy of the commons is easily solved through regulation. However, on a supranational level, where there is no overarching authority, governance mechanisms tend to collapse. The hard truth is that without robust enforcement of some kind, international cooperation is extremely difficult to maintain. This article proposes the following idea: governments joining (or already party to) an agreement, contribute an upfront deposit to an international regulatory body (the Commons Management Fund (“CMF”)) with the understanding that their contribution will be forfeited if they fail to honor their treaty commitments. The idea, while ostensibly simple, is deceptively complex. The focus is not the penalty, but rather the ability of governments to credibly signal commitment. In game theory, credible signaling can prevent a tragedy of the commons by generating confidence that everyone will stick to their commitments. The CMF is designed to exploit this effect. Now, more than ever, a solution to the tragedy of the commons on a supranational level is desperately needed—the CMF is such a solution

Gift-giving, Quasi-Credit and Reciprocity

The fluctuations in incomes inherent in rural communities can be attenuated by reciprocal assistance. A model of reciprocal assistance based upon rational action and voluntary participation is presented. Individuals provide assistance only if the costs of so doing are outweighed by the benefits from expected future reciprocation. A distinction is made between general reciprocity where the counter obligation is expected but not certain and balanced reciprocity where there is a firm counter obligation. This firm counter obligation is reflected by including a loan or quasi-credit element in any assistance. It is shown how this can increase the assistance given and it may explain the widespread use of quasi-credit in rural comunitities. Moreover it is shown that for a range of parameter values consistent with evidence from three villages in southern India, a simple scheme of gift-giving and quasi-credit can do almost as well as theoretically better but more complicated schemes.implicit contract, gift giving, reciprocity, quasi-credit

Eye quietness and quiet eye in expert and novice golf performance: an electrooculographic analysis

Quiet eye (QE) is the final ocular fixation on the target of an action (e.g., the ball in golf putting). Camerabased eye-tracking studies have consistently found longer QE durations in experts than novices; however, mechanisms underlying QE are not known. To offer a new perspective we examined the feasibility of measuring the QE using electrooculography (EOG) and developed an index to assess ocular activity across time: eye quietness (EQ). Ten expert and ten novice golfers putted 60 balls to a 2.4 m distant hole. Horizontal EOG (2ms resolution) was recorded from two electrodes placed on the outer sides of the eyes. QE duration was measured using a EOG voltage threshold and comprised the sum of the pre-movement and post-movement initiation components. EQ was computed as the standard deviation of the EOG in 0.5 s bins from –4 to +2 s, relative to backswing initiation: lower values indicate less movement of the eyes, hence greater quietness. Finally, we measured club-ball address and swing durations. T-tests showed that total QE did not differ between groups (p = .31); however, experts had marginally shorter pre-movement QE (p = .08) and longer post-movement QE (p < .001) than novices. A group × time ANOVA revealed that experts had less EQ before backswing initiation and greater EQ after backswing initiation (p = .002). QE durations were inversely correlated with EQ from –1.5 to 1 s (rs = –.48 - –.90, ps = .03 - .001). Experts had longer swing durations than novices (p = .01) and, importantly, swing durations correlated positively with post-movement QE (r = .52, p = .02) and negatively with EQ from 0.5 to 1s (r = –.63, p = .003). This study demonstrates the feasibility of measuring ocular activity using EOG and validates EQ as an index of ocular activity. Its findings challenge the dominant perspective on QE and provide new evidence that expert-novice differences in ocular activity may reflect differences in the kinematics of how experts and novices execute skills

Origins and structure of social and political attitudes: insights from personality system theory and behavioural genetics

People differ, often strikingly, in their views on desired social structures and processes. For example, while some value ethnic diversity in their society, others believe non -indigenous individuals (whatever that might mean) should be repatriated to their land of origin. Similarly, whereas some believe religion should play no role in determining social policy, others strongly advocate the importance of living according to religious scripture, including at a social level. This variation in attitudes, and its implication for societal cohesion, has made research on the origins of social and political attitudes of enduring interest to psychologists, sociologists, political scientists, among many others.The goal of the current thesis was to extend work in this literature in two key ways: Firstly, I examined whether political attitudes can be understood within a personality system model. This work addresses previous mixed results on the links of basic personality traits to political conservatism. In Chapter 3, I test predictions from this model; namely, that direct influences on political behaviour flow from moral values, with personality mostly acting indirectly via these moral values, rather than directly affecting political attitudes. Findings from two studies (published as Lewis & Bates, 2011a) supported these predictions suggesting that the new model helps explain inconsistencies in previous research attempting to link personality to political orientation that have not included the intermediary level of values.Secondly, I examined the genetic architecture of social attitudes constructs in three separate studies. Chapter 4 addressed whether in -group favouritism reflects heritable effects, and, secondly, whether race -favouritism was accounted for broad or specific genetic effects. Results indicated that a common biological mechanism exists facilitating generalised favouritism, with evidence for additional genetic effects specific to each form of group favouritism. These findings (published as Lewis & Bates, 2010) suggest that (at least) at the genetic level, race favouritism is multiply determined.In Chapter 5, I examined whether prosocial obligations across the domains of welfare, work, and civic obligation share a common genetic basis, or reflect specific heritable components (published as Lewis & Bates, 2011b). In females, results indicated the existence of a common heritable factor underlying each of these prosocial obligations. In males, a prosocial factor was also observed; familial effects (genetic and shared -environment effects were indistinguishable) influenced this general mechanism. At the domain -specific level, modest genetic effects were observed in females for civic and work obligations, with shared - environment effects influencing welfare obligations. In males, genetic influences were observed for welfare obligation, with unique -environments affecting work and civic duty.Finally, in Chapter 6, I present work examining the genetic architecture of religious belief. Although genetic factors are known to influence strength of religious belief, the psychological mechanism(s) through which this biological influence is manifest are presently unknown. Two non -theological constructs - 1) need for community integration and 2) need for existential certainty - were hypothesised to account for the genetic effects on religiosity. The results supported this hypothesis, with genetic influences on these traits wholly accounting for the heritable basis of religiosity, suggesting that religion "re- uses" systems involved in meeting both social and existential needs
