This paper tests the degree to which Sunstein's law of group polarization predicts the increase or decrease in polarization among individuals in an out-group during a polarizing event. The authors use the discourse on Parler surrounding the events of January 6th as a case study.

The study includes an overall sentiment analysis, a statistical analysis of emotions, along with eight other feelings, including anger, anticipation, disgust, fear, joy, sadness, surprise and trust. Specifically, the authors measure the differences in feelings related language used in posts as they pertain to Donald Trump and the Make America Great Again (MAGA) movement vs. Trump's Vice President Mike Pence both before and after January 6, 2021. The authors use this empirical analysis to show whether polarization in the Parler community increased or decreased after January 6th.

The authors find evidence that there is more complexity to polarization than Sunstein's theory would predict. The authors would expect a very polarized outed group to become more polarized relative to the general public after a central event; however, the authors see two extremes emerging within the Parler community (both strongly positive and strongly negative feelings toward Trump). The authors do not see unanimous consent across the Parler platform as Sunstein's theory would suggest; the out-group is becoming more polarized relative to the rest of the population. Instead, the authors observe a wide mix in reactions. The results of this study demonstrate that there is dissent even among the Parler echo chamber. For many themes surrounding the January 6th riots, Parler users express strong disagreement with each other and a lack of unity in their feelings for former President Trump.

The results suggest further research into polarization of outed groups and the policy implications of their polarization changes over time.

Increases in group polarization are often a motivator for public policy and are further becoming a major focus for research. Brookings' authors Stephanie Forrest and Joshua Daymude point to polarization as a substantial threat to American society, claiming “reducing extreme polarization is key to stabilizing democracy” (2022). Researchers Diana Epstein and John D. Graham demonstrate that polarized politics has impacted the “substance of rulemaking, judicial decisions, and legislation” along with “complicating long-term policy changes” (2007). The authors study how entrepreneurs have responded to this increase in polarization and its implications for public policy.

Not only does group polarization impact all types of groups, from the social to the economic, but also it has “particular implications for insulated ‘outgroups’” (Sunstein, 1999, p. 21). Groups that are excluded by either coercion or choice from dialog with other groups become even more polarized and extreme (Sunstein, 1999; Turner et al., 1989).

The authors have engaged in an empirical analysis that no other paper has addressed. This paper summarized the Parler sample data set and analyzed various themes associated with the events of January 6th, namely President Trump and MAGA themes and Vice President Pence. The analysis demonstrated a dramatic increase in negative sentiment and emotion related to Vice President Mike Pence after January 6th as well as mixed support for President Trump and an increase in disgust before and after the Capitol riot.

1. Introduction Victorian librarians saw the public library as a place where citizens could find material relating to their contemporary community — its health, finance, welfare and educational organisations; it would also be a depository for items relating to its past. By 1901 the Cambridge Free Library had taken so much care in this regard that “the historian of the future will find here all that he will need and that is as it should be”. But priorities changed within the library service. Within 50 years 60 per cent of that material had been dispersed and the remainder moved out of public view where it lay largely unused and unremembered. It had no place in the post‐war priorities of the public library service which had turned instead to “current information”, lists of societies, tourist information and the development of a general reference service concentrating on areas of comprehensiveness such as bus and train timetables from across the country. Today, community information and computer databases are the current information priorities, and although the unique, comprehensive local collection has been revived, invigorated and republicised, it remains an oddity, non‐conforming to the pre‐ordained management structure, an “albatross inheritance”.

This evening I am grateful for the opportunity in this company of reviewing the state of the art of lexicography. It is an area of human skill and expertise which is not often discussed in public, and my hosts, the University of Strathclyde and Collins, are to be commended for offering this annual forum. Collins are also to be commended for their remarkable contribution to the practice of lexicography in recent years. Their bilingual dictionaries, as you must know, are market leaders, and Collins English Dictionary has established a new standard and style in monolingual lexicography.

The case is presented by a senior marketing major (Tim), who did a business internship in the new products area of a fictitious consumer package goods firm. The case is presented as a journal Tim kept while interning. It is based on the author’s own journal, kept while working as a business professor intern in a firm similar to that in the case. Although names have been disguised, most of the activities, practices and problems described in the case are based on the author’s internship experience. Tim is simultaneously involved in two major new product projects. First is the early exploratory research done for new vegetable‐based food products. Second is a snack product which is ready to be moved from a controlled store test to test markets. Tim is also involved in other activities: a new business committee meeting, an industry forum, and a strategic plans presentation meeting. Tim works fairly closely with the new products manager, people in other areas of the firm such as marketing research and research and development, as well as with the firm’s ad agency. The case also describes informational interviews Tim conducted with various functional managers in the company involved with new products, and it gives students a feel for all of the nitty gritty implementation details involved in new product work.

Purpose: The purpose of this chapter is to review and critically evaluate robots, artificial intelligence and service automation (RAISA) applications in the restaurant industry to educate professors, graduate students, and industry professionals.

Design/methodology/approach: This chapter is a survey of applications of RAISA in restaurants. The chapter is based on the review of professional and peer-reviewed academic literature, and the industry insight section was prepared based on a 50-minute interview with Mr. Juan Higueros, Chief Operations Officer of Bear Robotics.

Findings: Various case studies presented in this chapter illustrate numerous possibilities for automation: from automating a specific function to complete automation of the front of the house (e.g., Eatsa) or back of the house (e.g., Spyce robotic kitchen). The restaurant industry has already adopted chatbots; voice-activated and biometric technologies; robots as hosts, food runners, chefs, and bartenders; tableside ordering; conveyors; and robotic food delivery.

Practical implications: The chapter presents professors and students with a detailed overview of RAISA in the restaurant industry that will be useful for educational and research purposes. Restaurant owners and managers may also benefit from reading this chapter as they will learn about the current state of technology and opportunities for RAISA implementation.

Originality/value: To the best of the authors’ knowledge, this chapter presents the first systematic and in-depth review of RAISA technologies in the restaurant industry.
