    • Modeling nosocomial transmission of rotavirus in pediatric wards 

      Kribs, Christopher; Jusot, Jean-Francois; Vanhems, Philippe; Charles, Sandrine (Springer-VerlagDepartment of Mathematics and Curriculum & Instruction, University of Texas at Arlington, 2011)
      Nosocomial transmission of viral and bacterial infections is a major problem worldwide, affecting millions of patients (and causing hundreds of thousands of deaths) per year. Rotavirus infections affect most children ...
    • A cross-institutional collaborative model 

      Kribs, Christopher; Quebec Fuentes, Sarah; Parker, Yolanda; Epperson, James; Jorgensen, Theresa; Mallam, Winifred; Gawlik, Christina; Eddy, Colleen (Rapid Intellect, 2011)
      In this duoethnography, a narrative framework is used to present the perspectives of members of a cross-institutional collaborative working group of mathematics education researchers. This article provides an example of ...
    • An epidemiological approach to the spread of political third parties 

      Kribs, Christopher; Romero, Daniel M.; Mubayi, Anuj; Orbe, Clara (American Insttitue of Mathematical SciencesMathematics Department, University of Texas at Arlington, 2011-05)
      Third political parties are influential in shaping American politics. In this work we study the spread of a third party ideology in a voting population where we assume that party members/activists are more influential in ...
    • The role of the ratio of vector and host densities in the evolution of transmission modes in vector-borne diseases. The example of sylvatic Trypanosoma cruzi 

      Kribs, Christopher; Pelosse, Perrine (Department of Mathematics, University of Texas at Arlington, 2012)
      Pathogens may use different routes of transmission to maximize their spread among host populations. Theoretical and empirical work conducted on directly-transmitted diseases suggest that horizontal (i.e., through host ...
    • The role of adaptations in two-strain competition for sylvatic Trypanosoma cruzi transmission 

      Kribs, Christopher; Mubayi, Anuj (Taylor and Francis OnlineDepartment of Mathematics, University of Texas at Arlington, 2012-08)
      This study presents a continuous-time model for the sylvatic transmission dynamics of two strains of Trypanosoma cruzi enzootic in North America, in order to study the role that adaptations of each strain to distinct modes ...
    • Influence of vectors' risk-spreading strategies and environmental stochasticity on the epidemiology and evolution of vector-borne diseaes: the example of Chagas' disease 

      Kribs, Christopher; Pelosse, Perrine; Ginoux, Marine; Rabinovich, Jorge E.; Gourbiere, Sebastien; Menu, Frederic (Public Library of ScienceDepartment of Mathematics, University of Texas at Arlington, 2013)
      Insects are known to display strategies that spread the risk of encountering unfavorable conditions, thereby decreasing the extinction probability of genetic lineages in unpredictable environments. To what extent these ...
    • Metering effects in population systems 

      Kribs, Christopher; Camacho, Erika T.; Wirkus, Stephen (American Institute of Mathematical SciencesDepartment of Mathematics; Department of Curriculum and Instruction, University of Texas at Arlington, 2013)
      This study compares the effects of two types of metering (periodic resetting and periodic increments) on one variable in a dynamical system, relative to the behavior of the corresponding system with an equivalent level of ...
    • Sociological phenomena as multiple nonlinearities: MTBI's new metaphor for complex human interactions 

      Kribs, Christopher (American Institute of Mathematical SciencesDepartment of Mathematics, University of Texas at Arlington, 2013)
      Mathematical models are well-established as metaphors for biological and epidemiological systems. The framework of epidemic modeling has also been applied to sociological phenomena driven by peer pressure, notably in two ...
    • Influence of environmental factors on college alcohol drinking patterns 

      Kribs, Christopher; Bani, Ridouan; Hameed, Rasheed; Szymanowski, Steve; Greenwood, Priscilla; Mubayi, Anuj (American Institute of Mathematical SciencesDepartment of Mathematics, University of Texas at Arlington, 2013)
      Alcohol abuse is a major problem, especially among students on and around college campuses. We use the mathematical framework of [16] and study the role of environmental factors on the long term dynamics of an alcohol ...
    • The Mathematical and Theoretical Biology Institute - a model of mentorship through research 

      Kribs, Christopher; Camacho, Erika T.; Wirkus, Stephen (American Instutute of Mathematical SciencesDepartment of Mathematics; Department of Curriculum and Instruction, University of Texas at Arlington, 2013)
      This article details the history, logistical operations, and design philosophy of the Mathematical and Theoretical Biology Institute (MTBI), a nationally recognized research program with an 18-year history of mentoring ...
    • A metapopulation model for sylvatic T. cruzi transmission with vector migration 

      Kribs, Christopher; Crawford, Britnee (American Institute of Mathematical ScienceDepartment of Mathematics, University of Texas at Arlington, 2014-06)
      This study presents a metapopulation model for the sylvatic transmission of Trypanosoma cruzi, the etiological agent of Chagas' disease, across multiple geographical regions and multiple overlapping host-vector ...
    • Graphical analysis of evolutionary trade-off in sylvatic Trypanosoma cruzi transmission modes 

      Kribs, Christopher (ElsevierDepartment of Mathematics, University of Texas at Arlington, 2014-07)
      **Please note that the full text is embargoed** ABSTRACT: The notion of evolutionary trade-off (one attribute increasing at the expense of another) is central to the evolution of traits, well-studied especially in life-history ...
    • Modeling colony collapse disorder in honeybees as a contagion 

      Kribs, Christopher David; Mitchell, Christopher (American Institute of Mathematical SciencesDepartment of Mathematics, University of Texas at Arlington, 2014-12)
      Honeybee pollination accounts annually for over $14 billion in United States agriculture alone. Within the past decade there has been a mysterious mass die-off of honeybees, an estimated 10 million beehives and sometimes ...
    • Host switching vs. host sharing in overlapping sylvatic Trypanosoma cruzi transmission cycles 

      Kribs, Christopher David; Mitchell, Christopher (Taylor & Francis OpenDepartment of Mathematics, University of Texas at Arlington, 2015-09)
      The principle of competitive exclusion is well established for multiple populations competing for the same resource, and simple models for multistrain infection exhibit it as well when cross-immunity precludes coinfections. ...
    • Agent-based mathematical modeling as a tool for estimating T. cruzi vector-host contact rates
