8 pages, Public perception about the reality of climate change has remained polarized and propagation of fake information on social media can be a potential cause. Homophily in communication, the tendency of people to communicate with others having similar beliefs, is understood to lead to the formation of echo chambers which reinforce individual beliefs and fuel further increase in polarization. Quite surprisingly, in an empirical analysis of the effect of homophily in communication on the level of polarization using evidence from Twitter conversations on the climate change topic during 2007–2017, we find that evolution of homophily over time negatively affects the evolution of polarization in the long run. Among various information about climate change to which people are exposed to, they are more likely to be influenced by information that have higher credibility. Therefore, we study a model of polarization of beliefs in social networks that accounts for credibility of propagating information in addition to homophily in communication. We find that polarization can not increase with increase in homophily in communication unless information propagating fake beliefs has minimal credibility. We therefore infer from the empirical results that anti-climate change tweets are largely not credible.
Via online journal, Purpose: Rural advisory services ensure agricultural information is disseminated to rural populations, yet they are less accessible to women. This research provides insight on gender differences in information access by investigating frequency of use and preference of agricultural information sources by gender in a rural setting, differentiated according to literacy and age. Design/Methodology/approach: This study interviewed 401 male/female individuals in farm households in Jhang and Bahawalpur district of Punjab, Pakistan in 2016. Findings: Men and women farmers’ use and preferences in accessing information sources are extremely different. Women hardly use sources for agricultural information, and value interpersonal communication from informal sources. In contrast, men use and value official agencies more. Radio, surprisingly, was very rarely used, contradicting previous findings of research elsewhere. Age and literacy affect differences between women more than it does between men, particularly for convenient locations to access information. Practical implications The study identified and refined major gender differences regarding use and preference for agricultural information in relation to age and literacy, and helps to articulate options to improve gender equality of access to agricultural information in Pakistan. Theoretical implications: The focus and outcomes regarding gender intersecting with age and literacy in agricultural information access imply the need for more refined socio-economic models, discerning and interrelating gender and other social dimensions beyond the standard of male-headed households. Originality/value: This paper adds to the growing body of evidence on information access according to gender, highlighting the need to investigate deeper socio-cultural issues around age and literacy.
Presents "some of the challenges arising from the growing amounts of information available and exhausting the managements when defining the direction of future development of a company."
12 pages., Authors presented an algorithm to analyze the behaviour of users of Twitter involving the environment and health care. To illustrate, they presented a concrete example of how the associated graph structure of the tweets related to World Environment Day 2019 was used to develop a heuristic analysis of the validity of the information.

30 pages., via online journal., In this article we present and discuss two experiments designed to test the effectiveness of the Internet as a tool of agricultural information. Subjects were cotton producers from Thessaly, Greece. Findings suggest that, in the early stages of an innovation diffusion process, the Internet is more effective than social sources (Experiment 1). However, when urgent situations that force quick decisions occur (Experiment 2), the Internet is significantly less effective than face-to-face communication channels. In both cases, farmers who used the Internet spent more time and devoted extra effort. The experiments proved that agronomists remain the most effective information source. Results also illustrate that Internet adoption is not necessarily synonymous with its use.
