A set of four econometric models is presented to examine the tour and episode-related attributes (specifically, mode choice, activity duration, travel times, and location choice) of the activity-travel patterns of non-workers, as a sequel to an earlier work by Bhat and Misra (2001), which presented a comprehensive continuous-time framework for representation and analysis of the activity-travel choices of nonworkers. Detailed descriptions of the first two components of the modeling framework related to the number and sequence of activity episodes are also presented. The proposed models using activity-travel data from the 1990 San Francisco Bay Area travel diary survey are estimated.

Worker Activity

Analysis of activity-travel patterns is an important component of any activity-based transportation planning exercise. Most of the current activity-travel literature focuses on studying the characteristics of workers. In comparison, little emphasis has been placed on studying non-worker activity-travel patterns. The results of an exploratory analysis of the activity-travel patterns of nonworkers in the San Francisco Bay Area are presented. The attributes of a nonworker’s overall activity-travel pattern are examined in terms of three dimensions: number of stops of each activity type, trip chaining, and the temporal sequencing of activities. Implications for transportation planning and policy analysis are discussed.

Research on travel demand modeling has predominantly focused on weekday activity–travel patterns, with studying the effects of commute travel on peak period traffic congestion as a major objective. Few studies have examined the weekend activity–travel behavior of individuals. However, weekend travel volume has been increasing over time and is comparable to weekday travel volumes. Hence, weekend activity–travel patterns warrant careful attention in transportation planning. This paper focuses on presenting a comprehensive exploratory analysis of weekend activity–travel patterns and contrasting weekday and weekend activity participation characteristics. Data from the 2000 San Francisco Bay Area Travel Survey, California, are used in the analysis. A comparative analysis of several aggregate activity–travel characteristics indicates that, although weekday and weekend travel volumes are comparable, there are several key differences in activity–travel characteristics. Specifically, weekend activity–travel is predominantly leisure oriented and undertaken during the midday period. Average trip distances are longer on weekends. Transit shares are lower but occupancy levels in personal automobiles are higher on weekends. The weekend activity sequencing and trip-chaining characteristics explored in this study provide further insights into individuals’ activity organization patterns on weekend days. This paper highlights the importance of studying weekend activity–travel behavior for transportation planning and air-quality modeling. Insights from this exploratory analysis can form the basis for comprehensive weekend activity–travel modeling efforts.

Wide Acceptance

In the 1970s, Japanese cooks began to appear in the kitchens of nouvelle cuisine chefs in France for further training, with scores more arriving in the next decades. Paul Bocuse, Alain Chapel, Joël Robuchon, and other leading French chefs started visiting Japan to teach, cook, and sample Japanese cuisine, and ten of them eventually opened restaurants there. In the 1980s and 1990s, these chefs' frequent visits to Japan and the steady flow of Japanese stagiaires to French restaurants in Europe and the United States encouraged a series of changes that I am calling the “Japanese turn,” which found chefs at fine-dining establishments in Los Angeles, New York City, and later the San Francisco Bay Area using an ever-widening array of Japanese ingredients, employing Japanese culinary techniques, and adding Japanese dishes to their menus. By the second decade of the twenty-first century, the wide acceptance of not only Japanese ingredients and techniques but also concepts like umami (savory tastiness) and shun (seasonality) suggest that Japanese cuisine is now well known to many American chefs.

Drag Queens

Researchers and practitioners have much to learn from drag queens, specifically Latinx queens, as they leverage everyday queerness and brownness in ways that contribute to pedagogy locally and globally, individually and collectively. Drawing on previous work examining the digital queer gestures of drag queen educators (Lizárraga & Cortez, 2019), this essay explores how non-dominant people that exist and fluctuate in the in-between of boundaries of gender, race, sexuality, the physical, and the virtual provide pedagogical overtures for imagining and organizing for new possible futures that are equitable and just. Further animated by Donna Haraway’s (2006) influential feminist post-humanist work, we interrogate how Latinx drag queens as cyborgs use digital technologies to enhance their craft and engage in powerful pedagogical moves. This essay draws from robust analyses of the digital presence of and interviews with two Latinx drag queens in the San Francisco Bay Area, as well as the online presence of a Xicanx doggie drag queen named RuPawl. Our participants actively drew on their liminality to provoke and mobilize communities around socio-political issues. In this regard, we see them engaging in transformative public cyborg jotería pedagogies that are made visible and historicized in the digital and physical world.
