Gender is a defining feature of informal/precarious work in the twenty-first century, yet studies rarely adopt a gendered lens when examining collective efforts to challenge informality and precarity. This chapter foregrounds the gendered dimensions of informal/precarious workers’ struggles as a crucial starting point for re-theorizing the future of global labor movements. Drawing upon the findings of the volume’s six chapters spanning five countries (the United States, Canada, South Korea, Mexico, and India) and two gender-typed sectors (domestic work and construction), this chapter explores how gender is intertwined into informal/precarious workers’ movements, why gender is addressed, and to what end. Across countries and sectors, informal/precarious worker organizations are on the front lines of challenging the multiple forms of gendered inequalities that shape contemporary practices of accumulation and labor regulation. They expose the forgotten reality that class structures not only represent classification struggles around work, but also around social identities, such as gender, race, and migration status. However, these organizing efforts are not fighting to transform the gendered division of labor or embarking on revolutionary struggles to overturn private ownership and liberalized markets. Nonetheless, these struggles are making major transformations in terms of increasing women’s leadership and membership in labor movements and exposing how gender interacts with other ascriptive identities to shape work. They are also radicalizing hegemonic scripts of capitalist accumulation, development, and even gender to attain recognition for female-dominated occupations and reproductive needs for the first time ever. These outcomes are crucial as sources of emancipatory transformations at a time when state and public support for labor and social protection is facing a deep assault stemming from the pressures of transnational production and globalizing markets.

The purpose of this paper is to investigate why users are willing to diffuse healthcare knowledge in social media by drawing on the communicative ecology theory (CET) and prior research on interpersonal communication.

This paper conducts a large-scale scenario-based online survey in WeChat (the most popular social media platform in China) to test the proposed research model and hypotheses. The final data set consists of 1,039 useful responses from WeChat users.

The results indicate that interestingness, emotionality and institution-based trust are the strongest antecedents in predicting healthcare knowledge-diffusing likelihood, followed by usefulness, source credibility and positivity. Further, the relationship between institution-based trust and healthcare knowledge-diffusing likelihood is partially mediated by source credibility.

Healthcare practitioners who seek to motivate individuals to disseminate healthcare knowledge need to phrase or frame healthcare knowledge in a way that draws greater interest, evokes stronger emotion, increases perceived usefulness or reflects positively on themselves. Healthcare organizations should also pay attention to strengthening users’ trust in the platform and source-related information that can indicate source authority.

This study is one of the first to investigate the dissemination of healthcare knowledge in the context of social media (WeChat in particular). Compared with other types of information, healthcare knowledge is more scientific and professional to the extent that most laypersons do not have relevant expertise to directly evaluate whether the content is credible and of high quality. Rather, their sharing likelihood is dependent more on other factors than perceived information quality and credibility; those factors include platform-related factors that may play an important role but has been overlooked in prior literature on interpersonal communication. By combining CET with interpersonal communication-related research and including institution-based trust as an important determinant of healthcare knowledge dissemination, this study provides a comprehensive analysis of healthcare knowledge diffusion process.

Natural disasters are increasingly more frequent and intense, which makes it critical for emergency managers to engage social media users during crises. This study examined emergency official accounts' social media engagement at each disaster stage based on Fink's four-stage model of crisis and disaster: prodromal, acute, chronic and termination stages and linked topics and sentiments to engagement.

Using text mining and sentiment analysis, 1,226 original tweets posted by 66 major emergency official Twitter accounts and more than 15,000 retweets elicited across the life cycle of Hurricane Irma were analyzed.

Results identified the most engaging official accounts and tweets. Most tweets and the most engaging tweets were posted in the prodromal stage. Tweets related to certain topics were significantly more engaging than others. The most frequently tweeted topics by official accounts were less engaging than some seldom tweeted topics. Negative sentiment words increased the engagingness of the tweet. Sadness was the strongest predictor of tweet engagement. Tweets that contained fewer sadness words were more engaging. Fear was stronger in positively predicting tweet engagement than anger. Results also demonstrated that words for fear and anger were critical in engaging social media discussions in the prodromal stage. Words for sadness made the tweets less engaging in the chronic stage.

This study provided detailed instructions on how to increase the engagingness of emergency management official accounts during disasters using computational methods. Findings have practical implications for both emergency managers and crisis researchers.

IN order to be able to discriminate with certainty between butter and such margarine as is sold in England, it is necessary to carry out two or three elaborate and delicate chemical processes. But there has always been a craving by the public for some simple method of determining the genuineness of butter by means of which the necessary trouble could be dispensed with. It has been suggested that such easy detection would be possible if all margarine bought and sold in England were to be manufactured with some distinctive colouring added—light‐blue, for instance—or were to contain a small amount of phenolphthalein, so that the addition of a drop of a solution of caustic potash to a suspected sample would cause it to become pink if it were margarine, while nothing would occur if it were genuine butter. These methods, which have been put forward seriously, will be found on consideration to be unnecessary, and, indeed, absurd.
