TL;DR: In this article, an ensemble of 59 twentieth century climate simulations from 17 WCRP CMIP3 models was analyzed to evaluate relative model credibility associated with a 75-member projection ensemble from the same 17 models.
Abstract: Ensembles of historical climate simulations and climate projections from the World Climate Research Programme's (WCRP's) Coupled Model Intercomparison Project phase 3 (CMIP3) multi-model dataset were investigated to determine how model credibility affects apparent relative scenario likelihoods in regional risk assessments. Methods were developed and applied in a Northern California case study. An ensemble of 59 twentieth century climate simulations from 17 WCRP CMIP3 models was analyzed to evaluate relative model credibility associated with a 75-member projection ensemble from the same 17 models. Credibility was assessed based on how models realistically reproduced selected statistics of historical climate relevant to California climatology. Metrics of this credibility were used to derive relative model weights leading to weight-threshold culling of models contributing to the projection ensemble. Density functions were then estimated for two projected quantities (temperature and precipitation), with and without considering credibility-based ensemble reductions. An analysis for Northern California showed that, while some models seem more capable at recreating limited aspects twentieth century climate, the overall tendency is for comparable model performance when several credibility measures are combined. Use of these metrics to decide which models to include in density function development led to local adjustments to function shapes, but led to limited affect

01 Apr 2013TL;DR: It is found that the consideration of user credibility and opinion subjectivity is essential for aggregating microblog opinions and the proposed mechanism can effectively discover market intelligence (MI) for supporting decision-makers.
Abstract: Given their rapidly growing popularity, microblogs have become great sources of consumer opinions. However, in the face of unique properties and the massive volume of posts on microblogs, this paper proposes a framework that provides a compact numeric summarization of opinions on such platforms. The proposed framework is designed to cope with the following tasks: trendy topics detection, opinion classification, credibility assessment, and numeric summarization. An experiment is carried out on Twitter, the largest microblog website, to prove the effectiveness of the proposed framework. We find that the consideration of user credibility and opinion subjectivity is essential for aggregating microblog opinions. The proposed mechanism can effectively discover market intelligence (MI) for supporting decision-makers.

TL;DR: In this article, the authors examined the relationship between source credibility, self-presentation, and consumer behavior towards micro-celebrity endorsements and found that users deem microcelebrities credible if they follow certain criteria of online behavior and self-Presentation.
Abstract: Companies increasingly use micro-celebrities for product endorsement However, there are concerns around the self-presentation and credibility of this source of information online This study examines the relationships between source credibility, self-presentation, and consumer behavior towards micro-celebrity endorsements In-depth interviews were conducted with 38 female active users of Instagram, from Russia, to explore the impact of micro-celebrities’ credibility and self-presentation upon consumer purchase decisions This study attempts to construct an extended source credibility framework applicable to the online context The findings show that users deem micro-celebrities credible if they follow certain criteria of online behavior and self-presentation

TL;DR: In this paper, the authors re-examined the impact of personal and organizational values congruence on positive work outcomes and investigated the extent to which this relationship is affected by demographic variables.
Abstract: This study re-examined the impact of personal and organizational values congruency on positive work outcomes and investigated the extent to which this relationship is affected by demographic variables. Data collection paralleled an earlier study (Posner and Schmidt, Journal of Business Ethics 12, 1993, 341) and validated those findings, lending additional credibility to the continuing importance of this phenomenon. Both personal values congruence and organizational values clarity were significantly related to commitment, satisfaction, motivation, anxiety, work stress, and ethics using a cross-sectional sample of 711 managers from across the United States. Gender, educational level, and functional area did not impact these relationships, although years of experience (expressed by age, managerial experience, and hierarchical level) did make a difference.
