Biró","doi":"arxiv-2311.04826","DOIUrl":"https://doi.org/arxiv-2311.04826","url":null,"abstract":"At a first glance lottery is a form of gambling, a game in which the chances\u0000of winning is extremely small. But upon a deeper look, considering that the\u0000Jackpot prize of lotteries is a result of the active participation of millions\u0000of players, we come to the conclusion that the interaction of the simple rules\u0000with the high number of players creates an emergent complex system. Such a\u0000system is characterized by its time-series that presents some interesting\u0000properties. Given the inherent stochastic nature of this game, it can be\u0000described within a mean-field type approach, such as the one implemented in the\u0000Local Growth and Global Reset (LGGR) model. We argue that the Jackpot\u0000time-series behaves ergodic for six lotteries with diverse formats and player\u0000pools. Specifying this consideration in the framework of the LGGR model, we\u0000model the lotteries with growth rates confirmed by the time-series. The reset\u0000rate is deduced mathematically and confirmed by data. Given these parameters we\u0000calculate the probability density of the Jackpot prizes, that fits well the\u0000experimentally observed ones. We propose to use a single w parameter, as the\u0000product of the player pools found under the jurisdiction of the lottery and the\u0000chance that a single lottery ticket wins.","PeriodicalId":501348,"journal":{"name":"arXiv - PHYS - Popular Physics","volume":"172 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138522947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data visualizations\u0000are central to bringing these viewpoints to broader publics. However,\u0000visualizations often conceal the many contexts involved in their production,\u0000ranging from decisions made in research labs about collecting and sharing data\u0000to choices made in editorial rooms about which data stories to tell. In this\u0000paper, we examine how data visualizations about climate change and COVID-19 are\u0000produced in popular science magazines, using Scientific American, an\u0000established English-language popular science magazine, as a case study. To do\u0000this, we apply the analytical concept of \"data journeys\" (Leonelli, 2020) in a\u0000mixed methods study that centers on interviews with Scientific American staff\u0000and is supplemented by a visualization analysis of selected charts. In\u0000particular, we discuss the affordances of working with open data, the role of\u0000collaborative data practices, and how the magazine works to counter\u0000misinformation and increase transparency. This work provides a theoretical\u0000contribution by testing and expanding the concept of data journeys as an\u0000analytical framework, as well as practical contributions by providing insight\u0000into the data (visualization) practices of science communicators.","PeriodicalId":501348,"journal":{"name":"arXiv - PHYS - Popular Physics","volume":"79 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138522944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our findings demonstrate that the\u0000interplay between the feeding index and mosquito abatement strategy is rather a\u0000complex phenomenon and it induces a heterogeneous contact rates that should be\u0000included while modelling multi-host, multi-vector transmission model.","PeriodicalId":501348,"journal":{"name":"arXiv - PHYS - Popular Physics","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138523062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
