Does Facebook enable ideological segregation in political news consumption? We analyzed exposure to during the US 2020 election using aggregated data for 208 million users. compared inventory of all that users could have seen their feeds with information they saw (after algorithmic curation) and which engaged. show (i) is high increases as we shift from potential actual engagement; (ii) there an asymmetry between conservative liberal audiences, a substantial corner ecosystem consumed...
Computer- and Internet-supported education (CISE) has many advantages over the traditional face-to-face education, which been part of human cultural heritage for thousands years. One key challenges CISE systems is to accomplish augmented interaction during whole learning process by providing both comprehensive well-coordinated functionalities facilitate educational activities geographically distributed participants. In this paper, online classroom model (OCM) proposed guide design,...
Purpose The large-scale construction of China’s transportation infrastructure has driven the flow elements between regions, which provided convenient conditions for accumulation advantageous resources. Design/methodology/approach Based on panel data 31 provinces in China past 2003-2017 years, this paper applies spatial econometric model and partial differential method empirically analyzes spillover effect employment service industry under four weighting matrices. Findings results show that...
The year 2020 will be remembered for two events of global significance: the COVID-19 pandemic and U.S. Presidential Election. In this chapter, we summarize recent studies using large public Twitter data sets on these issues. We have three primary objectives. First, delineate epistemological practical considerations when combining traditions computational research social science research. A sensible balance should struck stakes are high between advancing theory concrete, timely reporting...
The research about the coordinated relationship between transportation accessibility and economic linkage has important theoretical practical significance. This paper uses revised spatial interaction model to analyze rail network its pattern then explores gravity calculate intensity of cities in Jing-Jin-Ji metropolitan area. Based on them, construct a coupling coordination evaluate Results show that disparity degree area is extremely uneven, with large difference degree, poor edge cities....
This paper examines the evolving meanings of liberty and equality over a long historical span, comparing their democratic significance from semantic perspective. Liberty equality, as fundamental principles, complement contest each other. To explore relevance using text-based approach, I trained diachronic word embeddings on large corpus structured texts, marked by decade, spanning early 19th century to 2020. The analysis reveals that, since 1960s, has increasingly emerged more democratically...
<p>Although modern data-driven campaigning (DDC) is not entirely new, scholars have typically relied on reports and interviewers of practitioners to understand its use. However, the advent public ad libraries from Meta Google provides an opportunity measure scope variation in DDC practice advertising across different types sponsors within platforms. Using textual audiovisual processing, we create a database ads 2022 U.S. elections. These data allow us index that quantifies extent at...
Industrial agglomeration, population expansion lead to urban sprawl, the contradictions between high degree of concentration central city and reach ability are core issues that must be addressed in process urbanization. Urban transport network city's industrial agglomeration exists a close relationship, accumulation certain scale requires transportation, can guide development form. The effectiveness transportation is basis for rationalization form, determines efficiency boundary. This...
Service Supply Chain (SSC) have seen considerable attention in the business circles and academia. However, little focused on Integrator (SI), especially research results about SI competitiveness its influencing factors context of SSC has not yet appeared. This paper study formation mechanism (SIC) under perspective structural model. Data collection consisted an network questionnaire survey resulted 252 usable responses. Research show that collaborative capability (CC), integrating (IC1),...
Based on the panel data of 247 prefecture-level and above cities in China from 2006 to 2016, this paper establishes a spatial Dubin model (SDM) study spillover effect mechanism improvement inter-city accessibility caused by high-speed rail urban innovation capabilities. The found that improved improves city's capabilities as whole, has significant positive neighboring cities. In sub-sample regression Tier 1 5 different scales, is most text further construct provincial-inverse distance nested...
