The Story of Robert and Susan Davis( And Why They\u27re so Damn Homest!)
A fascinating real-world example of microeconomic theory can be used to analyze the above Cleaver family. The thought process behind a certain decision made by Robert and Susan represent game theory and dominant strategies. In a scandal that shook suburbia, Robert and Susan Davis each had extramarital affairs that could have led to the devastating end of a picture-perfect marriage. Decisions made by each are analyzed and predicted below using the game theory model. The adulterers each planned strategies regarding their secret love-affairs to bring about the best outcome for themselves. Although Robert and Susan may not have realized why they made the decisions they did, game theory can help explain how each arrived at his/her final decision
Voltage-controlled inversion of tunnel magnetoresistance in epitaxial Nickel/Graphene/MgO/Cobalt junctions
We report on the fabrication and characterization of vertical spin-valve
structures using a thick epitaxial MgO barrier as spacer layer and a
graphene-passivated Ni film as bottom ferromagnetic electrode. The devices show
robust and scalable tunnel magnetoresistance, with several changes of sign upon
varying the applied bias voltage. These findings are explained by a model of
phonon-assisted transport mechanisms that relies on the peculiarity of the band
structure and spin density of states at the hybrid graphene|Ni interface
Are Home Offices Feasible in a University?: Faculty Perceptions of a Home Office Experiment
This article examines faculty perceptions of how the new technologies of E-mail and voice mail that were widely adopted as a result of the home office experiment changed the ways of working and ways of thinking about what is important. The authors discussed both first- and second-level effects of communication technologies in three areas: (1) on faculty interaction both within the department and in the larger campus community, (2) on student/faculty interaction, and (3) on work styles and the ways faculty members think about their work. When the home office project was envisioned, the goal was to use communication technology to create a work environment in which faculty without an office on campus could come to campus simply to teach classes and perhaps occasionally attend meetings, while performing most other duties off campus. The project seemed more palatable to most faculty in the department and to administrators because it was temporary, but it did require all faculty members to move twice within a three year period
Seed mass predicts migration lag of European trees
International audienceAbstractKey messageWe reanalysed a dataset of tree distribution ranges in Europe to identify which plant traits best explain migration potential in woody species. Contrary to our intuition that tree longevity would best explain the ability of trees to migrate, we found that seed biomass was the only good descriptor of migration potential: trees with heavier seeds lag more.ContextTo cope with global warming, the majority of plants have either to migrate polewards or risk extinction. This is why conservationists value predictive models that can flag plant species that may not keep pace with global warming.AimsTo identify which plant traits best explain migration potential in woody species by reanalysing a dataset of tree distribution ranges in Europe.MethodsWe used two statistical approaches to quantify migration lag. A direct approach compared frequency of large trees in the two latitudinal extremes and a modelling approach in which we first corrected data for the influence of temperature and then assessed the influence of latitude over the entire distribution of the tree species.ResultsContrary to our intuition that tree longevity would best explain the ability of trees to migrate, we found that seed mass was the only good descriptor of migration potential: trees with heavier seeds lag more.ConclusionWe interpret our results in terms of the well-established trade-off between seed mass and seed production in spermatophytes and discuss the possible functional implications that will result from selectively losing large-seeded trees. In summary, we provide an empirical study on how woody communities will respond to global warming over the next years
Trastorno por juego en internet, cogniciones sociadas y deterioros cognitivos relacionados: Una revisión sistemática utilizando las directrices PRISMA
Background: Empirical research studies have highlighted the need to investigate the underlying cognitions and cognitive variables in relation to Internet Gaming Disorder (IGD). However, little is known about the possible cognitive-related impairments associated with IGD. Objectives: The present paper extends previous research and uncovers additional key general cognitive-related outcomes of IGD via a systematic review of the empirical literature. Methods: The PRISMA (Preferred Reporting Item for Systematic Reviews and Meta-analysis) guidelines were adopted. Internet-based bibliographic searches were conducted via seven major electronic databases (i.e., PsycARTICLES, PsycINFO, Web of Science, Core Collection BIOSIS Citation Index, MEDLINE, SciELO Citation Index, and PubMed) to access studies examining the association between IGD and cognitive outcomes. Results: A total of 17 empirical studies meeting the inclusion criteria that investigated the relationships between IGD and cognitions and/or cognitive-related outcomes were identified. Seven distinct cognitions and another ten distinct cognitiverelated impairments associated with IGD were identified. Conclusion: The present review found empirical evidence supporting the association of IGD with particular types of cognitions and specific cognitiverelated impairments.Introducción: Investigaciones empíricas han puntualizado la necesidad de indagar sobre las cogniciones subyacentes y las variables cognitivas asociadas con el Trastorno por Juego en Internet (IGD, por sus siglas en inglés). Sin embargo, es escaso el conocimiento sobre los posibles deterioros cognitivos asociados con el IGD. Objetivos: El presente estudio extiende la investigación previa y revela resultados generales de procesos cognitivos del IGD a través de una revisión sistemática de la literatura empírica. Método: Se adoptaron las directrices PRISMA (Preferred Reporting Item for Systematic Reviews and Meta-analysis). Se realizaron búsquedas bibliográficas a través de siete bases de datos electrónicas (p.e., PsycARTICLES, PsycINFO, Web of Science, Core Collection BIOSIS Citation Index, MEDLINE, SciELO Citation Index y PubMed) para acceder a los estudios que examinan la relación entre IGD y resultados cognitivos. Resultados: Un total de 17 estudios empíricos que examinaban la relación entre IGD y cogniciones y/o resultados cognitivos cumplieron con los criterios de inclusión. Se identificaron siete cogniciones distintivas y otros diez deterioros cognitivos relacionados con el IGD. Conclusión: No existe evidencia para sustentar la asociación entre el IGD y determinados tipos de cogniciones y deficiencias cognitivas específicas
Extinction risk of soil biota
No species lives on earth forever. Knowing when and why species go extinct is crucial for a complete understanding of the consequences of anthropogenic activity, and its impact on ecosystem functioning. Even though soil biota play a key role in maintaining the functioning of ecosystems, the vast majority of existing studies focus on aboveground organisms. Many questions about the fate of belowground organisms remain open, so the combined effort of theorists and applied ecologists is needed in the ongoing development of soil extinction ecology
