We analyzed the e ects of team members’ behavioral strategies, team size, and team diversity on overall performance. Depending on the landscape complexity and a team’s features a teammay eventually find the best possible solution or become trapped at a local maximum. Hard-working agents can explore more solutions per unit time, while risk-taking agents inject randomness in the solutions they test. We found that when teams solve complex problems, both strategies (risk-taking and hard work) have positive impacts on the final score, and the positive e ect of moderate risktaking is substantial. However, risk-taking has a negative e ect on how quickly a team achieves its final score. If time restrictions can be relaxed, a moderate level of risk can produce an improved score. If the highest priority is instead to achieve the best possible score in the shortest amount of time, the hard work strategy has the greatest impact. When problems are simpler, risk-taking behavior has a negative e ect on performance, while hard work decreases the time required to solve the problem. We also find that larger teams generally solved problems more e ectively, and that some of this positive e ect is due to the increase in diversity. We showmore generally that increasing the diversity of teams has a positive impact on the team’s final score, while morediverse teamsalso require less time to reach their final solution. Thiswork contributesoverall to the larger literature on collective problem solving in teams.","PeriodicalId":14675,"journal":{"name":"J. Artif. Soc. Soc.

We present an agent-based model of decision-making and influences on food choice, and apply it to historically observed trends of British whole and skimmed (including semi) milk consumption from 1974 to 2005. We aim to give a plausible representation of milk choice substitution, and test different mechanisms of choice consideration. Agents are consumers that perceive information regarding the two milk choices, and hold values that inform their position on the health and environmental impact of those choices. Habit, social influence and post-decision evaluation are modelled. Representative survey data on human values and long-running public concerns empirically inform the model. An experiment was run to compare two model variants by how they perform in reproducing these trends. This was measured by recording mean weekly milk consumption per person. The variants differed in how agents became disposed to consider alternative milk choices. One followed a threshold approach, the other was probability based. All other model aspects remained unchanged. An optimisation exercise via an evolutionary algorithm was used to calibrate the model variants independently to observed data. Following calibration, uncertainty and global variance-based temporal sensitivity analysis were conducted. Both model variants were able to reproduce the general pattern of historical milk consumption, however, the probability-based approach gave a closer fit to the observed data, but over a wider range of uncertainty. This responds to, and further highlights, the need for research that looks at, and compares, different models of human decision-making in agent-based and simulation models. This study is the first to present an agent-based modelling of food choice substitution in the context of British milk consumption. It can serve as a valuable pre-curser to the modelling of dietary shift and sustainable product substitution to plant-based alternatives in Britain.","PeriodicalId":14675,"journal":{"name":"J. Artif.

This study uses an empirically based, agent-based model to explore the e ect of six scenarios on both area of land covered by, as well as the quality of SWC structures in three Kebeles (villages) of Boset District. The analysis revealed that integratingmultiple interventions enhanced SWCmost in all Kebeles. Furthermore, increasing the commitment of local government through capacity building generated most e ect and yet required the lowest investment. Motivating farmers, introducing alternative livelihood opportunities and establishing and strengtheningmicro-watershed associations had limited, but di erential influence on the outcomes across the Kebeles. However, all alternative scenarios had someadded value compared todoingbusiness as usual. Hence, in order to enhance the outcomes and sustainability of the ongoing CBWMprogram in the study area and other similar localities, it is crucial to pay much more attention to increasing the commitment of local government actors throughcapacity building. This empowers local government actors to (1) planandmoree iciently implement the program in consultation with other local actors, and (2) integrate locally sensitive need-based adaptation of the program.","PeriodicalId":14675,"journal":{"name":"J.

However, thesedataofteninformusatthemacro-levelofanalysisbutnotabouttheroleofindividuals’behavioursin the emergence of long-term patterns. Therefore, it is difficult to infer ‘how’ and ‘why’ certain patterns emerged in the past. Historians use various methods to draw hypotheses about the underlying reasons for emerging patterns and trends, but since the patterns are the results of hundreds if not thousands of years of human behaviour, these hypotheses can never be tested in reality. Our proposition is that simulation models and specifically, agent-based models (ABMs) can be used as complementary tools in historical studies to support hypothesis building. The approach that we propose and test in this paper is to design and configure models in such a way as to generate historical patterns, consequently aiming to find individual-level explanations for the emerging pattern. In this work, we use an existing, empirically validated, agent-based model of common pool resource management to test hypotheses formulated based on a historical dataset. We first investigate whether the model can replicate various patterns observed in the dataset, and second, whether it can contribute to a better understanding of the underlying mechanism that led to the observed empirical trends. We showcase how ABM can be used as a complementary tool to support theory development in historical studies. Finally, we provide some guidelines for using ABM as a tool to test historical hypotheses","PeriodicalId":14675,"journal":{"name":"J. Artif. Soc. Soc.
