The Size Conundrum: Why Online Knowledge Markets Can Fail at Scale

In this paper, we interpret the community question answering websites on the StackExchange platform as knowledge markets, and analyze how and why these markets can fail at scale. A knowledge market framing allows site operators to reason about market failures, and to design policies to prevent them. Our goal is to provide insights on large-scale knowledge market failures through an interpretable model. We explore a set of interpretable economic production models on a large empirical dataset to analyze the dynamics of content generation in knowledge markets. Amongst these, the Cobb-Douglas model best explains empirical data and provides an intuitive explanation for content generation through concepts of elasticity and diminishing returns. Content generation depends on user participation and also on how specific types of content (e.g. answers) depends on other types (e.g. questions). We show that these factors of content generation have constant elasticity---a percentage increase in any of the inputs leads to a constant percentage increase in the output. Furthermore, markets exhibit diminishing returns---the marginal output decreases as the input is incrementally increased. Knowledge markets also vary on their returns to scale---the increase in output resulting from a proportionate increase in all inputs. Importantly, many knowledge markets exhibit diseconomies of scale---measures of market health (e.g., the percentage of questions with an accepted answer) decrease as a function of number of participants. The implications of our work are two-fold: site operators ought to design incentives as a function of system size (number of participants); the market lens should shed insight into complex dependencies amongst different content types and participant actions in general social networks.Comment: The 27th International Conference on World Wide Web (WWW), 201

The Minimized Face of Internal Communication: An Exploration of How Public Relations Agency Websites Frame Internal Communication and its Connection to Social Media

Internal communication is increasingly vital to organizational success due to the influence of social media, yet it remains understudied within public relations research. Using a qualitative content analysis of 181 websites, this study examines how leading public relations agency websites frame the value of internal communication and its connection to social media. Findings reveal internal communication is largely missing from the frame. When explicitly referenced, it is mostly framed as synonymous with employee communication as a means for management to communicate to employees, though some portrayals are more robust. Websites frame internal communication’s value as enhancing financial outcomes by improving workplace culture, employee engagement, and workers’ willingness to support management’s preferred organization brand or reputation. Social media are disconnected from internal communication and are mostly framed as tools that require additional employee training to use in order to reach external audiences. A handful of agencies urge organizations to include social media and internal stakeholders within the internal communication function. Recommendations are made for future internal communication research and practice

Thoughts about a General Theory of Influence in a DIME/PMESII/ASCOP/IRC2 Model

The leading question of this paper is: “How would influence warfare (“iWar”) work and how can we simulate it?” The paper discusses foundational aspects of a theory and model of influence warfare by discussing a framework built along the DIME/PMESII/ASCOP dimension forming a prism with three axes. The DIME concept groups the many instruments of power a nation state can muster into four categories: Diplomacy, Information, Military and Economy. PMESII describes the operational environment in six domains: Political, Military, Economic, Social, Information and Infrastructure. ASCOPE is used in counter insurgency (COIN) environments to analyze the cultural and human environment (aka the “human terrain”) and encompasses Areas, Structures, Capabilities, Organization, People and Events. In addition, the model reflects about aspects of information collection requirements (ICR) and information capabilities requirements (ICR) - hence DIME/PMESII/ASCOP/ICR2. This model was developed from an influence wargame that was conducted in October 2018. This paper introduces basic methodical questions around model building in general and puts a special focus on building a framework for the problem space of influence/information/hybrid warfare takes its shape in. The article tries to describe mechanisms and principles in the information/influence space using cross discipline terminology (e.g. physics, chemistry and literature). On a more advanced level this article contributes to the Human, Social, Culture, Behavior (HSCB) models and community. One goal is to establish an academic, multinational and whole of government influence wargamer community. This paper introduces the idea of the perception field understood as a molecule of a story or narrative that influences an observer. This molecule can be drawn as a selection of vectors that can be built inside the DIME/PMESII/ASCOP prism. Each vector can be influenced by a shielding or shaping action. These ideas were explored in this influence wargame

The Effects of Emotional Versus Rational Message Framing on Brand Attachment and Brand Loyalty

The purpose of this research is to investigate the relationship among message framing in social media, brand attachment, and brand loyalty for higher education institutions. In particular, this study compares the effectiveness of rational versus emotional message framing in different message contexts, such as sports or academic-related stories. Furthermore, this study examines the congruent effect between message framing and contents in higher education. Specifically, this study predicts that the more message framing and contents are congruent, the greater brand attachment and brand loyalty consumers will have. To analyze the effects of message framing and type of contents, this study adopts experimental design method. The findings of this research indicate that previous involvement with a brand predicts high brand attachment and brand loyalty and needs to be present prior to the strengthening process of brand attachment and brand loyalty. Therefore, previous brand involvement can be measured and related to the effectiveness of strengthening brand attachment and brand loyalty

Comparing the relationship between knowledge and support for hydraulic fracturing between residents of the United States and the United Kingdom

Our work examines the relationship between knowledge/familiarity with shale gas development in a comparative context. The United States (US) and United Kingdom (UK) represent very different cases of shale gas development, with development relatively mature in the US whilst, no extraction of shale gas has yet commenced in the UK. Comparing results from two national level survey efforts in 2014, we find higher levels of knowledge about the shale gas industry in the UK than in the US, as well as higher levels of support in the US (opposition levels were similar, but US respondents were much less likely than UK respondents to say that they did not know whether they supported or opposed development). With respect to the relationship between knowledge and support, increased knowledge in the UK is associated with increased support, while knowledge was unrelated to support in the US. We anchor these results within the information deficit model of science, suggesting that concentrated media and governance in the UK have played an important role in producing the demonstrated effects
