Making Bicycling Comfortable: Identifying Minimum Infrastructure Needs by Population Segments Using a Video Survey
In this study, researchers use survey data to analyze bicycling comfort and its relationship with socio-demographics, bicycling attitudes, and bicycling behavior. An existing survey of students, faculty, and staff at UC Davis (n=3089) who rated video clips of bicycling environments based on their perceived comfort as a part of the UC Davis annual Campus Travel Survey (CTS) is used. The video clips come from a variety of urban and semi-rural roads (designated California state highways) around the San Francisco Bay Area where bicycling rates vary. Results indicate considerable effects of socio-demographics and attitudes on absolute video ratings, but relative agreement about which videos are most comfortable and uncomfortable across population segments. In addition, presence of bike infrastructure and low speed roads are the strongest video factors generating more comfortable ratings. However, the results suggest that even the best designed on-road bike facilities are unlikely to provide a comfortable bicycling environment for those without a predisposition to bicycle. This suggests that protected and separated bike facilities may be required for many people to consider bicycling. Nonetheless, the results provide guidance for improving roads with on-street bike facilities where protected or separated facilities may not be suitable.View the NCST Project Webpag

Investigating the Influence of Dockless Electric Bike-share on Travel Behavior, Attitudes, Health, and Equity
Cities throughout the world have implemented bike-share systems as a strategy for expanding mobility options. While these have attracted substantial ridership, little is known about their influence on travel behavior more broadly. The aim of this study was to examine how shared electric bikes (e-bikes) and e-scooters influence individual travel attitudes and behavior, and related outcomes of physical activity and transportation equity. The study involved a survey in the greater Sacramento area of 1959 households before (Spring 2016) and 988 after (Spring 2019) the Summer 2018 implementation of the e-bike and e-scooterservice operated by Jump, Inc., as well as a direct survey of 703 e-bike users (in Fall 2018 & Spring 2019). Among householdrespondents, 3–13% reported having used the service. Of e-bike share trips, 35% substituted for car travel, 30% substituted for walking, and 5% were used to connect to transit. Before- and after-household surveys indicated a slight decrease in self-reported (not objectively measured) median vehicle miles traveled and slight positive shifts in attitudes towards bicycling. Service implementation was associated with minimal changes in health in terms of physical activity and numbers of collisions. The percentages of users by self-reported student status, race, and income suggest a fairly equitable service distribution by these parameters, but each survey under-represents racial minorities and people with low incomes. Therefore, the study is inconclusive about how this service impacts those most in need. Furthermore, aggregated socio-demographics of areas where trips started or ended did not correlate with, and therefore are not reliable indicators of, the socio-demographics of e-bike-share users. Thus, targeted surveying of racial minorities and people with low-incomes is needed to understand bike-share equity
The Gender Wage Gap in Utah
In 2016, American women earned approximately 20% less than men. This gap has narrowed substantially since 1963, when the Equal Pay Act was passed and women earned 41% less than men; yet a gap persists, and a half century later women are still paid less than men in almost every occupation. In Utah, a woman earns approximately 71 cents per dollar that a man earns (though reports vary, several recent national studies show a gap between 70–71 cents), and according to the American Association for University Women, we have the nation’s fourth-largest gender wage gap for year-round full-time workers. With 43.9% of Utah’s workforce comprised of women and 72.1% of adult women participating in the paid workforce in the past 12 months (slightly higher than the national average of 71.5%), this topic is highly relevant to the wellbeing of Utah women. Closing the gender wage gap will strengthen women’s economic impact in their families, communities, and the state
Cosmetic Surgery and Body Image Among Utah Women
National media and scholars have puzzled over the high levels of plastic surgery among Utah women, and a national magazine even called Salt Lake City the “Vainest City in America.” Many wonder why Salt Lake City, capital of one of the most religious states in the nation, would employ more plastic surgeons per capita than Los Angeles. In fact, two-thirds of Utah Mormon women know someone who has undergone cosmetic plastic surgery. In a state known for its conservative and wholesome values, visitors are surprised at the large quantity of billboards lining Utah’s interstate freeway advertising plastic surgery and other body manipulating procedures. Pinning down causes for this phenomenon is difficult, but this report will attempt to shed light on the cultural and personal factors contributing to the high numbers of elective plastic surgeries (specifically for aesthetic purposes) in Utah
Complexity Embodied: Using Body Mapping to Understand Complex Support Needs
Arts-based methods reduce reliance on verbal communication. This makes them particularly useful for exploring sensitive and controversial topics, which can often be difficult to articulate verbally, and capturing the experiences and insights of marginalised groups including people with complex support needs. The visual arts-based method of body mapping provides an alternative way for participants to express their views and experiences through non-verbal storytelling. In this article, we report on the adaptation of body mapping to conduct research with two disadvantaged groups: adults with cognitive disability and complex support needs; and young people with complex support needs. We identify the potential of the method to promote participants\u27 choice and control over the research process and the onus on researchers to create and maintain a mutually safe and supportive environment. Body mapping is also identified as a useful practical tool for use by individuals and their supporters. Arts-based methods, including body mapping, have the potential to empower people with complex support needs to engage more fully in research, which provides a greater understanding of their experiences, views, and feelings
Considerations for Successful Counterspeech
It may sometimes seem that the Internet is sullied by a relentless tide of hatred, vitriol, and extremist content, and that not much can be done to respond effectively. Such content cannot all be deleted, after all, since even if a statement, image, or user is deleted from one platform, there is always somewhere else to go.We have been pleasantly surprised, however, that our study of Twitter turned up numerous cases of effective counterspeech, which we define as a direct response to hateful or dangerous speech. Based on this first, qualitative study of counterspeech as it is practiced spontaneously on Twitter, we offer some preliminary suggestions on which strategies may help to make counterspeech successful
Counterspeech on Twitter: A Field Study
As hateful and extremist content proliferates online, 'counterspeech' is gaining currency as a means of diminishing it. No wonder: counterspeech doesn't impinge on freedom of expression and can be practiced by almost anyone, requiring neither law nor institutions. The idea that 'more speech' is a remedy for harmful speech has been familiar in liberal democratic thought at least since U.S. Supreme Court Justice Louis Brandeis declared it in 1927. We are still without evidence, however, that counterspeech actually diminishes harmful speech or its effects. This would be very hard to measure offline but is a bit easier online, where speech and responses to it are recorded. In this paper we make a modest start. Specifically we ask: in what forms and circumstances does counterspeech - which we define as a direct response to hateful or dangerous speech - favorably influence discourse and perhaps even behavior?To our knowledge, this is the first study of Internet users (not a government or organization) counterspeaking spontaneously on a public platform like Twitter. Our findings are qualitative and anecdotal, since reliable quantitative detection of hateful speech or counterspeech is a problem yet to be fully solved due to the wide variations in language employed, although we made progress, as reported in an earlier paper that was part of this project (Saleem, Dillon, Benesch, & Ruths, 2016).We have identified four categories or "vectors" in each of which counterspeech functions quite differently, as hateful speech also does: one-to-one exchanges, many-to-one, one-to-many, and many-to-many. We also present a set of counterspeech strategies extrapolated from our data, with examples of tweets that illustrate those strategies at work, and suggestions for which ones may be successful
Aligning systems science and community-based participatory research: A case example of the Community Health Advocacy and Research Alliance (CHARA).
Partnered research may help bridge the gap between research and practice. Community-based participatory research (CBPR) supports collaboration between scientific researchers and community members that is designed to improve capacity, enhance trust, and address health disparities. Systems science aims to understand the complex ways human-ecological coupled systems interact and apply knowledge to management practices. Although CBPR and systems science display complementary principles, only a few articles describe synergies between these 2 approaches. In this article, we explore opportunities to utilize concepts from systems science to understand the development, evolution, and sustainability of 1 CBPR partnership: The Community Health Advocacy and Research Alliance (CHARA). Systems science tools may help CHARA and other CBPR partnerships sustain their core identities while co-evolving in conjunction with individual members, community priorities, and a changing healthcare landscape. Our goal is to highlight CHARA as a case for applying the complementary approaches of CBPR and systems science to (1) improve academic/community partnership functioning and sustainability, (2) ensure that research addresses the priorities and needs of end users, and (3) support more timely application of scientific discoveries into routine practice
Dynamic Resting-State Functional Connectivity in Major Depression
Major depressive disorder (MDD) is characterized by abnormal resting-state functional connectivity (RSFC), especially in medial prefrontal cortical (MPFC) regions of the default network. However, prior research in MDD has not examined dynamic changes in functional connectivity as networks form, interact, and dissolve over time. We compared unmedicated individuals with MDD (n=100) to control participants (n=109) on dynamic RSFC (operationalized as SD in RSFC over a series of sliding windows) of an MPFC seed region during a resting-state functional magnetic resonance imaging scan. Among participants with MDD, we also investigated the relationship between symptom severity and RSFC. Secondary analyses probed the association between dynamic RSFC and rumination. Results showed that individuals with MDD were characterized by decreased dynamic (less variable) RSFC between MPFC and regions of parahippocampal gyrus within the default network, a pattern related to sustained positive connectivity between these regions across sliding windows. In contrast, the MDD group exhibited increased dynamic (more variable) RSFC between MPFC and regions of insula, and higher severity of depression was related to increased dynamic RSFC between MPFC and dorsolateral prefrontal cortex. These patterns of highly variable RSFC were related to greater frequency of strong positive and negative correlations in activity across sliding windows. Secondary analyses indicated that increased dynamic RSFC between MPFC and insula was related to higher levels of recent rumination. These findings provide initial evidence that depression, and ruminative thinking in depression, are related to abnormal patterns of fluctuating communication among brain systems involved in regulating attention and self-referential thinking
