Given the highly coupled nature of human-environment systems, we cannot fully understand these systems without considering reciprocal causality, or `' feedbacks.” This analysis focuses on the Chitwan District of south-central Nepal, a high priority conservation area, and seeks to address the question of how feedbacks between land use and microlevel human decision making impact the decadal time scale dynamics of population and land-use change. It investigates two feedback loops connecting land use and demographic decision making: agricultural land use - marriage timing; and agricultural land use - fertility. Marriage is closely tied to land use in Chitwan because new households in Chitwan are established primarily after marriage. Fertility is connected to land use because of its linkage with population size and future new household formation. However, prior research in Chitwan has shown that residents of agricultural neighborhoods tend to marry earlier, and to have children sooner after marriage. Using an agent-based model, we compare model outcomes from scenarios with and without these feedback loops. Our results indicate that these feedbacks lead to statistically significant differences in population and in land-use outcomes. However, the sizes of these differences are relatively small in magnitude (less than 8% for the scenarios considered here), even over a 50-year time scale. These findings are a reminder that CHANS researchers must be careful to consider both effect size and significance when considering the policy implications of model outcomes.", "publicationTitle": "ECOLOGY AND SOCIETY", "publisher": "", "place": "", "date": "2014", "volume": "19", "issue": "2", "section": "", "partNumber": "", "partTitle": "", "pages": "", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.5751/ES-06243-190231", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1708-3087", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Feedback" }, { "tag": "Land use" }, { "tag": "author: Alex Zvoleff" }, { "tag": "codeurl: http://www.openabm.org/model/3640/version/1/view" }, { "tag": "coupled human-natural system" }, { "tag": "docs: ODD" }, { "tag": "email: azvoleff@conservation.org" }, { "tag": "environment" }, { "tag": "fertility" }, { "tag": "marriage" }, { "tag": "platform: Python" }, { "tag": "population" }, { "tag": "spon" }, { "tag": "sponsor: National Science Foundation" } ], "collections": [ "3HM4CEW5", "8IF4C9B3" ], "relations": { "dc:replaces": "http://zotero.org/groups/289063/items/VQBJ6E6D", "owl:sameAs": "http://zotero.org/users/540283/items/K56Z4ZI8" }, "dateAdded": "2014-11-12T02:28:41Z", "dateModified": "2015-05-13T16:30:07Z" } }, { "key": "HCZ5WX28", "version": 3573, "library": { "type": "group", "id": 289063, "name": "Workbench-CML", "links": { "alternate": { "href": "https://www.zotero.org/groups/workbench-cml", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/289063/items/HCZ5WX28", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/workbench-cml/items/HCZ5WX28", "type": "text/html" } }, "meta": { "createdByUser": { "id": 540283, "username": "majanssen", "name": "Marco Janssen", "links": { "alternate": { "href": "https://www.zotero.org/majanssen", "type": "text/html" } } }, "creatorSummary": "Zheng et al.", "parsedDate": "2014-08-01", "numChildren": 0 }, "data": { "key": "HCZ5WX28", "version": 3573, "itemType": "journalArticle", "title": "Agent-based model for electricity consumption and storage to evaluate economic viability of tariff arbitrage for residential sector demand response", "creators": [ { "creatorType": "author", "firstName": "Menglian", "lastName": "Zheng" }, { "creatorType": "author", "firstName": "Christoph J.", "lastName": "Meinrenken" }, { "creatorType": "author", "firstName": "Klaus S.", "lastName": "Lackner" } ], "abstractNote": "Demand response (DR) is one of many approaches to address temporal mismatches in demand and supply of grid electricity. More common in the commercial sector, DR usually refers to reducing consumption at certain hours or seasons, thus reducing peak demand from the grid. In the residential sector, where sophisticated appliance-level controls such as automatic dimming of lights or on-demand lowering of air conditioning are less common, building-based electricity storage to shift grid consumption from peak to off-peak times could provide DR without requiring consumers to operate their appliances on shifted or reduced schedules: Storage would be dispatched to appliances as needed while still shaving peaks on the grid. Technologically, storage and two-way-inverters are readily available to enable such residential DR Economically, however, the situation is less clear. Specifically, are time-varying electricity tariffs available such that electricity cost reduction via arbitrage could offset manufacturing, financing, and installation costs of the required storage? To address this question we (i) devise an agent-based appliance-level stochastic model to simulate the electricity demand of an average U.S. household; (ii) loadshift the demand via simple dispatch strategies; and (iii) determine potential profits to the building owner, i.e. reduced electricity cost of the modified demand with realistic tariffs (Con Edison, NY) minus storage cost. We determine the economic viability for a range of traditional and advanced storage technologies as well as their optimum storage capacities to maximize profits. We find that (i) profits can range from <1% to 48% of annual electricity costs of a typical household; and (ii) optimum capacities, while approximately equal to households' kWh consumption during peak hours, is affected by stochastic variations in daily and seasonal consumption. Future improvements to storage technology, arbitrage strategies, and tariffs are discussed.

Bird behavior is represented in a spatially explicit agent-based model that tracks responses of individuals to predicted changes in local habitat quantity and quality. We apply this framework to the endangered California clapper rail (Rallus longirostris obsoletus) in the San Francisco Estuary, US, under a range of sea-level rise and conservation scenarios aimed at clapper rail recovery. The framework enables quantification of the relationship between critical habitat destruction and clapper rail population decline. The most influential factors that characterize the quality of tidal marsh habitat are salinity, which is a proxy for higher quality nesting environment and abundance of macroinvertebrates, and tidal conditions, which affect flood and predation threats. Results suggest that clapper rail viability should remain at the present level for moderate sea level rise. However, for a rise of 1.66 m, extinction risk increases from 0.01 to 0.36. The framework enables quantitative evaluation of proposed conservation efforts, and should complement existing theory and empirical inferences. Compared with sub-regional efforts, estuary-wide conservation is more effective in improving reproduction and dispersal success and accommodates a sea-level rise of an additional 10 cm before population falls below criticality. Should sea level rise to the predicted maximum, proposed conservation efforts are likely to be ineffective in preventing California clapper rail extinction by 2100. (C) 2014 Elsevier Ltd.

Unhealthy eating is a complex-system problem. We used agent-based modeling to examine the effects of different policies on unhealthy eating behaviors. Methods. We developed an agent-based simulation model to represent a synthetic population of adults in Pasadena, CA, and how they make dietary decisions. Data from the 2007 Food Attitudes and Behaviors Survey and other empirical studies were used to calibrate the parameters of the model. Simulations were performed to contrast the potential effects of various policies on the evolution of dietary decisions. Results. Our model showed that a 20% increase in taxes on fast foods would lower the probability of fast-food consumption by 3 percentage points, whereas improving the visibility of positive social norms by 10%, either through community-based or mass-media campaigns, could improve the consumption of fruits and vegetables by 7 percentage points and lower fast-food consumption by 6 percentage points. Zoning policies had no significant impact. Conclusions. Interventions emphasizing healthy eating norms may be more effective than directly targeting food prices or regulating local food outlets.

We conduct a series of experiments using the agent-based simulation modeling technique to identify strategically located firms in a network that can significantly influence the process of software diffusion. Our findings suggest that: 1) structural location of organizations does significantly influence the process of diffusion; and 2) the criteria for identifying strategically located firms depend on contextual factors, such as network topology, network density, and interoperability costs. To illustrate the practical use of these results, we propose a “network-aware” pricing strategy that takes advantage of information regarding organizational social networks.

The system implements econometric and statistical models that represent travel and decision-making behavior throughout the evacuation process. The system considers six typical evacuation decisions: evacuate/stay, accommodation type choice, evacuation destination choice, mode choice, vehicle usage choice, and departure time choice. It explicitly captures the shadow evacuation population. In addition, the model system captures pre-evacuation preparation activities using an activity-based approach. A demonstration study that predicts activity-travel patterns using model parameters estimated for the Miami-Dade area for a hypothetical category-4 hurricane is discussed. The simulation results clearly indicate the model system produces a distribution of choice patterns that is consistent with sample observations and existing literature. The model system also identifies the proportion of the shadow evacuation population and their geographical extent. About 23% of the population outside the designated evacuation zone would evacuate.

An agent-based simulation model is developed to serve as the experimental ground for this analysis. Diffusion dynamics of a nonsticky innovation is investigated by varying homophily levels in the social network depicted in the model as the primary control variable. First of all, the results show that homophily is self-reinforcing. Second, starting from a nonhomophilous network, early increases in the level of homophily have a positive effect on the extent of diffusion, whereas further increases have a negative impact. Finally, several local minima and maxima are observed in the relation between the homophily level and the extent of diffusion. Our analysis focuses on node properties such as connectedness and average degrees in order to explain the observed regular relationship between homophily and diffusion. We argue that (i) homophily increases the connectedness of different status groups separately and (ii) increasing levels of homophily decreases the marginal importance of a single homophilous tie by increasing the sources of valuable information. Future research involves investigating the coevolution of social behavior and networks by allowing the adopted innovation to lead to value homophily, exploration of different diffusion initiation types, and different adoption heuristics.", "publicationTitle": "SOCIAL SCIENCE COMPUTER REVIEW", "publisher": "", "place": "", "date": "June 2014", "volume": "32", "issue": "3", "section": "", "partNumber": "", "partTitle": "", "pages": "354-372", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1177/0894439313512464", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "0894-4393", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Agent-based model" }, { "tag": "Segregation" }, { "tag": "Simulation" }, { "tag": "Social networks" }, { "tag": "author: Mustafa Yavaş" }, { "tag": "codeurl: none" }, { "tag": "diffusion" }, { "tag": "docs: pseudocode" }, { "tag": "email: mustafa.yavas@boun.edu.tr" }, { "tag": "formal models" }, { "tag": "homophily" }, { "tag": "platform: unknown" }, { "tag": "sponsor: Marie Curie Programme" }, { "tag": "threshold models" } ], "collections": [ "7DQ82DZ3" ], "relations": { "owl:sameAs": "http://zotero.org/users/540283/items/9JI6HUIM", "dc:replaces": "http://zotero.org/groups/289063/items/CJUXFECW" }, "dateAdded": "2014-11-12T02:28:41Z", "dateModified": "2015-05-13T16:29:35Z" } }, { "key": "G5FXTG9E", "version": 3573, "library": { "type": "group", "id": 289063, "name": "Workbench-CML", "links": { "alternate": { "href": "https://www.zotero.org/groups/workbench-cml", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/289063/items/G5FXTG9E", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/workbench-cml/items/G5FXTG9E", "type": "text/html" } }, "meta": { "createdByUser": { "id": 540283, "username": "majanssen", "name": "Marco Janssen", "links": { "alternate": { "href": "https://www.zotero.org/majanssen", "type": "text/html" } } }, "creatorSummary": "Yang et al.", "parsedDate": "2014-07", "numChildren": 0 }, "data": { "key": "G5FXTG9E", "version": 3573, "itemType": "journalArticle", "title": "Examining the Impact of the Walking School Bus With an Agent-Based Model", "creators": [ { "creatorType": "author", "firstName": "Yong", "lastName": "Yang" }, { "creatorType": "author", "firstName": "Ana", "lastName": "Diez-Roux" }, { "creatorType": "author", "firstName": "Kelly R.", "lastName": "Evenson" }, { "creatorType": "author", "firstName": "Natalie", "lastName": "Colabianchi" } ], "abstractNote": "We used an agent-based model to examine the impact of the walking school bus (WSB) on children's active travel to school.

In the model, virtual agricultural households exist in a hypothetical village. Farmers follow a self-adaptive approach to learn and understand policy variations, in order to make relevant decisions. The model has been validated through simulation of actual trends (the based-on-reality scenario). On the basis of this scenario, we further analyzed possible future trends in rural environmental pollution in China. Our results reflect that China may enter a period of farmer income stagnation accompanied by a rapid deterioration in rural environmental quality. Ammonia emission from livestock production may become the primary agricultural source of air pollution, and eutrophication is calculated to be the major water pollution issue for the long term. Synthetic fertilizer application is projected to be the dominant source of total nitrogen (N) and phosphorus (P) in aquatic system (contributing to about 64% and 46% of the total discharge, respectively).

Seeing the validity of the model, some initial assumptions were relaxed and two groups of experiments were carried out considering commuters' heterogeneity and memory limitations. The results showed that heterogeneous commuters' departure time distribution is broader and has a lower peak at equilibrium and different people behave in different pattern. When each commuter has a limited memory, some fluctuations exist in the evolutionary dynamics of the system, and hence an ideal equilibrium can hardly be reached.

In this research, we combine activity-based analysis with a movement-based approach to model the intra-urban human mobility observed from about 15 million check-in records during a yearlong period in Shanghai, China. The proposed model is activity-based and includes two parts: the transition of travel demands during a specific time period and the movement between locations. For the first part, we find the transition probability between activities varies over time, and then we construct a temporal transition probability matrix to represent the transition probability of travel demands during a time interval. For the second part, we suggest that the travel demands can be divided into two classes, locationally mandatory activity (LMA) and locationally stochastic activity (LSA), according to whether the demand is associated with fixed location or not. By judging the combination of predecessor activity type and successor activity type we determine three trip patterns, each associated with a different decay parameter. To validate the model, we adopt the mechanism of an agent-based model and compare the simulated results with the observed pattern from the displacement distance distribution, the spatio-temporal distribution of activities, and the temporal distribution of travel demand transitions. The results show that the simulated patterns fit the observed data well, indicating that these findings open new directions for combining activity-based analysis with a movement-based approach using social media check-in data.", "publicationTitle": "PLOS ONE", "publisher": "", "place": "", "date": "MAY 13 2014", "volume": "9", "issue": "5", "section": "", "partNumber": "", "partTitle": "", "pages": "", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1371/journal.pone.0097010", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1932-6203", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "author: Lun Wu" }, { "tag": "codeurl: none" }, { "tag": "docs: none" }, { "tag": "email: liuyu@urban.pku.edu.cn" }, { "tag": "platform: none" }, { "tag": "sponsor: NSFC" } ], "collections": [ "7DQ82DZ3" ], "relations": { "dc:replaces": "http://zotero.org/groups/289063/items/TG3DSA54", "owl:sameAs": "http://zotero.org/users/540283/items/9NC7UNKI" }, "dateAdded": "2014-11-12T02:28:41Z", "dateModified": "2015-05-13T16:29:06Z" } }, { "key": "5UGZ959E", "version": 3573, "library": { "type": "group", "id": 289063, "name": "Workbench-CML", "links": { "alternate": { "href": "https://www.zotero.org/groups/workbench-cml", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/289063/items/5UGZ959E", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/workbench-cml/items/5UGZ959E", "type": "text/html" } }, "meta": { "createdByUser": { "id": 540283, "username": "majanssen", "name": "Marco Janssen", "links": { "alternate": { "href": "https://www.zotero.org/majanssen", "type": "text/html" } } }, "creatorSummary": "Wren et al.", "parsedDate": "2014-04", "numChildren": 0 }, "data": { "key": "5UGZ959E", "version": 3573, "itemType": "journalArticle", "title": "The role of spatial foresight in models of hominin dispersal", "creators": [ { "creatorType": "author", "firstName": "Colin D.", "lastName": "Wren" }, { "creatorType": "author", "firstName": "Julian Z.", "lastName": "Xue" }, { "creatorType": "author", "firstName": "Andre", "lastName": "Costopoulos" }, { "creatorType": "author", "firstName": "Ariane", "lastName": "Burke" } ], "abstractNote": "Increasingly sophisticated hominin cognition is assumed to play an important role in major dispersal events but it is unclear what that role is. We present an agent-based model showing that there is a close relationship between level of foresight, environmental heterogeneity, and population dispersibility. We explore the dynamics between these three factors and discuss how they may affect the capacity of a hominin population to disperse. Generally, we find that high levels of environmental heterogeneity select for increased foresight and that high levels of foresight tend to reduce dispersibility. This suggests that cognitively complex hominins in heterogeneous environments have low dispersibility relative to cognitively less complex organisms in more homogeneous environments. The model predicts that the environments leading up to major episodes of dispersal, such as the initial hominin dispersal into Eurasia, were likely relatively low in spatial heterogeneity and that the dispersing hominins had relatively low foresight.

The ABM features representations of rules, behaviors, and constraints that affect person- and household-level decisions about marriage, reproduction, and infant mortality in hunter-gatherer systems. The demographic characteristics of the larger model system emerge through human-level interactions playing out in the context of global parameters that can be adjusted to produce a range of mortality and fertility conditions. Model data show a relationship between the OY ratios of living populations (the living OY ratio) and assemblages of dead individuals drawn from those populations (the dead OY ratio) that is consistent with that from empirically known ethnographic hunter-gatherer cases. The dead OY ratio is clearly related to the mean ages, mean adult mortality rates, and mean total fertility rates experienced by living populations in the model. Sample size exerts a strong effect on the accuracy with which the calculated dead OY ratio reflects the actual dead OY ratio of the complete assemblage. These results demonstrate that the dead OY ratio is a potentially useful metric for paleodemographic analysis of changes in mortality and mean age, and suggest that, in general, hunter-gatherer populations with higher mortality, higher fertility, and lower mean ages are characterized by lower dead OY ratios.

The development of this simulation model leverages the combination of massively data-parallel processing capabilities supported by NVidia's Compute Unified Device Architecture (CUDA) and the advanced spatial visualisation capabilities of GIS. These technologies have enabled the implementation of an individual-based, stochastic lifecycle and dispersal algorithm for the OWS fly invasion. The simulation model draws upon a wide range of biological data as input to stochastically determine the reproduction and survival of the OWS fly through the different stages of its lifecycle and dispersal of gravid females. Through this model, a highly efficient computational platform has been developed for studying the effectiveness' of control and mitigation strategies and their associated economic impact on livestock industries can be materialised.

According to the investors' structure, trading frequency and order submission in the real CSI 300 index futures market, our multi-agent system includes informed and uninformed traders, and the uninformed traders are classified into three types: intelligent traders, simple traders, and liquidity traders. We examine how tick size affects information dissemination efficiency and market liquidity by observing trading interaction between traders. In particular, we focus on examining price forecasting and order submission strategies. This multi-agent system reproduces key characteristics of the price dynamics and stylized facts observable in the real CSI 300 index futures market. Simulations show that tick size has a contrary impact on information dissemination efficiency and market liquidity. While reducing tick size improves market liquidity, it also reduces information dissemination efficiency. Therefore, decision-makers have to make a trade-off between information dissemination efficiency and market liquidity in terms of tick size. Our model contributes to building a multi-agent system realistically and thus reduces the modelling risk in policy design.

In the regime where repulsive forces dominate, the fluctuations generated by the active system give rise to quasi-long-range transitional order, but-unlike the thermal system-without creating topological defects.", "publicationTitle": "PHYSICAL REVIEW LETTERS", "publisher": "", "place": "", "date": "APR 25 2014", "volume": "112", "issue": "16", "section": "", "partNumber": "", "partTitle": "", "pages": "", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1103/PhysRevLett.112.168301", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "0031-9007", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [], "collections": [], "relations": { "owl:sameAs": "http://zotero.org/users/540283/items/HZ6TWHMP", "dc:replaces": "http://zotero.org/groups/289063/items/RIPECDRF" }, "dateAdded": "2014-11-12T02:28:41Z", "dateModified": "2015-05-13T16:28:30Z" } }, { "key": "GUXZ5I3A", "version": 3573, "library": { "type": "group", "id": 289063, "name": "Workbench-CML", "links": { "alternate": { "href": "https://www.zotero.org/groups/workbench-cml", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/289063/items/GUXZ5I3A", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/workbench-cml/items/GUXZ5I3A", "type": "text/html" } }, "meta": { "createdByUser": { "id": 540283, "username": "majanssen", "name": "Marco Janssen", "links": { "alternate": { "href": "https://www.zotero.org/majanssen", "type": "text/html" } } }, "creatorSummary": "Was and Lubas", "parsedDate": "2014-12-25", "numChildren": 0 }, "data": { "key": "GUXZ5I3A", "version": 3573, "itemType": "journalArticle", "title": "Towards realistic and effective Agent-based models of crowd dynamics", "creators": [ { "creatorType": "author", "firstName": "Jaroslaw", "lastName": "Was" }, { "creatorType": "author", "firstName": "Robert", "lastName": "Lubas" } ], "abstractNote": "The authors propose a new methodology for creating realistic and effective models of crowd dynamics, which takes into account the Agent-based approach combined with non-homogeneous and asynchronous Cellular Automata.

On the other hand, the use of the Agent-based approach makes it possible to apply different scenarios and situational contexts, namely competitive and non-competitive evacuation or free movement of pedestrians. The proposed approach was tested in large-scale test cases, namely the evacuation of the Allianz Arena football stadium in Munich and other stadiums like Wisla Krakow Stadium or GKS Tychy Stadium, as well as AGH University facilities.

Further, in the context of climate change, scholarly literature on migration ranges across a host of climatic stressors and geographies, making it difficult to date to solve the debate whether migration is a form of adaptation or an indicator of limits to adaptation. To address both of these debates, original research was undertaken to answer the question `under what circumstances do households (HHs) use migration as a risk management strategy when facing rainfall variability and food insecurity?'. This research administered a HH survey (n = 1300) and participatory research (n = 2000 respondents) in districts in eight countries (Guatemala, Peru, Ghana, Tanzania, Bangladesh, India, Thailand, and Vietnam). The findings reveal that the answer to how climatic stressors affect migration decisions and the degree to which migration improves the adaptive capacity of those HHs lie in the vulnerability of the HH and its sensitivity to climatic factors. The data reveal for the first time in a comparable global study distinct HH profiles of `resilience' and `vulnerability'. At the same time, the article distinguishes between `content' migration - rather associated with resilient HHs - and `erosive' migration - rather associated with vulnerable HHs. However, the article also highlights that there are not always clear cuts but very often grey areas and overlaps among the HHs of the study when applying these typologies. Moreover, the article relates these profiles to an agent-based modelling approach applied in the Tanzania case to explore under what scenarios rainfall variability and food security have the potential to become significant drivers of human mobility in particular regions of the world in the next two to three decades.", "publicationTitle": "CLIMATE AND DEVELOPMENT", "publisher": "", "place": "", "date": "JAN 2 2014", "volume": "6", "issue": "1, SI", "section": "", "partNumber": "", "partTitle": "", "pages": "1-17", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1080/17565529.2013.835707", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1756-5529", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Adaptation" }, { "tag": "Climate change" }, { "tag": "Migration" }, { "tag": "author: Koko Warmer" }, { "tag": "codeurl: none" }, { "tag": "docs: none" }, { "tag": "email: afifi@ehs.unu.edu" }, { "tag": "platform: none" }, { "tag": "sponsor: none" }, { "tag": "vulnerability" } ], "collections": [ "7DQ82DZ3" ], "relations": { "owl:sameAs": "http://zotero.org/users/540283/items/GMRMEG2F", "dc:replaces": "http://zotero.org/groups/289063/items/R9HF2CT3" }, "dateAdded": "2014-11-12T02:28:41Z", "dateModified": "2015-05-13T16:16:42Z" } }, { "key": "2ZIC7FGW", "version": 3559, "library": { "type": "group", "id": 289063, "name": "Workbench-CML", "links": { "alternate": { "href": "https://www.zotero.org/groups/workbench-cml", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/289063/items/2ZIC7FGW", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/workbench-cml/items/2ZIC7FGW", "type": "text/html" } }, "meta": { "createdByUser": { "id": 540283, "username": "majanssen", "name": "Marco Janssen", "links": { "alternate": { "href": "https://www.zotero.org/majanssen", "type": "text/html" } } }, "creatorSummary": "Wang et al.", "parsedDate": "2014-06", "numChildren": 1 }, "data": { "key": "2ZIC7FGW", "version": 3559, "itemType": "journalArticle", "title": "Multi-agent-based simulation on technology innovation-diffusion in China", "creators": [ { "creatorType": "author", "firstName": "Zheng", "lastName": "Wang" }, { "creatorType": "author", "firstName": "Zixuan", "lastName": "Yao" }, { "creatorType": "author", "firstName": "Gaoxiang", "lastName": "Gu" }, { "creatorType": "author", "firstName": "Fei", "lastName": "Hu" }, { "creatorType": "author", "firstName": "Xiaoye", "lastName": "Dai" } ], "abstractNote": "An innovation-diffusion model was developed with agent-based modelling (ABM); the model is used to study technical innovation and its diffusion process in China.

This study aims to use nontraditional innovative systems methods to examine: a) the effects of social norms on school children's BMI growth and fruit and vegetable (FV) consumption, and b) the effects of misperceptions of social norms on US children's BMI growth. Methods: We built an agent-based model (ABM) in a utility maximization framework and parameterized the model based on empirical longitudinal data collected in a US nationally representative study, the Early Childhood Longitudinal Study -Kindergarten Cohort (ECLS-K), to test potential mechanisms of social norm affecting children's BMI growth and FV consumption. Results: Intraclass correlation coefficients (ICC) for BMI were 0.064-0.065, suggesting that children's BMI were similar within each school. The correlation between observed and ABM-predicted BMI was 0.87, indicating the validity of our ABM. Our simulations suggested the follow-the-average social norm acts as an endogenous stabilizer, which automatically adjusts positive and negative deviance of an individual's BMI from the group mean of a social network. One unit of BMI below the social average may lead to 0.025 unit increase in BMI per year for each child; asymmetrically, one unit of BMI above the social average, may only cause 0.015 unit of BMI reduction. Gender difference was apparent. Social norms have less impact on weight reduction among girls, and a greater impact promoting weight increase among boys. Our simulation also showed misperception of the social norm would push up the mean BMI and cause the distribution to be more skewed to the left. Our simulation results did not provide strong support for the role of social norms on FV consumption. Conclusions: Social norm influences US children's BMI growth. High obesity prevalence will lead to a continuous increase in children's BMI due to increased socially acceptable mean BMI. Interventions promoting healthy body image and desirable socially acceptable BMI should be implemented to control childhood obesity epidemic.", "publicationTitle": "BMC PUBLIC HEALTH", "publisher": "", "place": "", "date": "SEP 6 2014", "volume": "14", "issue": "", "section": "", "partNumber": "", "partTitle": "", "pages": "", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1186/1471-2458-14-923", "citationKey": "", "url": "", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "1471-2458", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "English", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Agent-based model" }, { "tag": "Body mass index" }, { "tag": "Child" }, { "tag": "Healthy body image" }, { "tag": "Obesity" }, { "tag": "Overweight" }, { "tag": "Social norms" }, { "tag": "author: Youfa Wang" }, { "tag": "codeurl: none" }, { "tag": "docs: pseudocode" }, { "tag": "email: youfawan@buffalo.edu" }, { "tag": "networks" }, { "tag": "platform: Netlogo" }, { "tag": "sponsor: National Institute of Health" } ], "collections": [ "7DQ82DZ3" ], "relations": { "owl:sameAs": "http://zotero.org/users/540283/items/62SIZAFP", "dc:replaces": "http://zotero.org/groups/289063/items/MHZXKP7J" }, "dateAdded": "2014-11-12T02:28:41Z", "dateModified": "2015-05-13T16:16:31Z" } } ]
