Abstract The purpose of this investigation was to characterize factors that predict tap water mistrust among Phoenix, Arizona Latinx adults. Participants (n = 492, 28 ± 7 years, 37.4% female) completed water security experience-based scales and an Adapted Survey of Water Issues in Arizona. Binary logistic regression determined odds ratios (OR) with 95% confidence intervals (95% CI) for the odds of perceiving tap water to be unsafe. Of all participants, 51.2% perceived their tap water to be unsafe. The odds of mistrusting tap water were significantly greater for each additional favorable perception of bottled compared to tap water (e.g., tastes/smells better; OR = 1.94, 95% CI = 1.50, 2.50), negative home tap water experience (e.g., hard water mineral deposits and rusty color; OR = 1.32, 95% CI = 1.12, 1.56), use of alternatives to home tap water (OR = 1.25, 95% CI = 1.04, 1.51), and with decreased water quality and acceptability (OR = 1.21, 95% CI = 1.01, 1.45; P < 0.05). The odds of mistrusting tap water were significantly lower for those whose primary source of drinking water is the public supply (municipal) (OR = 0.07, 95% CI = 0.01, 0.63) and with decreased water access (OR = 0.56, 95% CI = 0.48, 0.66; P < 0.05). Latinx mistrust of tap water appears to be associated with organoleptic perceptions and reliance on alternatives to the home drinking water system.

“Nudge or Sludge? An In-Class Experimental Auction Illustrating How Misunderstood Scientific Information Can Change Consumer Behavior.
Scientific information can be used to help people understand and describe the world. For example, consumers regularly seek out information about their food and drink to help inform their purchasing decisions. Sometimes, however, consumers can respond negatively to this information, even when the information did not intend to convey a negative signal. These negative responses can be the result of misunderstandings or strong, visceral, emotional behavior, that can be challenging to foresee and once arisen, difficult (and expensive) to mitigate. In this paper, we show how educators can use an in-class economic experiment to introduce the power of a sludge—a small behavioral intervention that leads to worse outcomes. We provide a step-by-step guide to take students through a demand revealing design using a second-price, willingness-to-accept (WTA) auction that tests preferences for tap water and bottled water when students receive total dissolved solids (TDS) information. Additional classroom discussion topics are presented, including comparing nudges and sludges, the public response to the treatment of tap water, and the role of safety information in consumer response.

Purpose This study aims to determine preference and concerns regarding tap vs bottled water and recommendations to increase tap water use in a US Midwest university. The authors propose interventions to increase tap water use based on survey results. Design/methodology/approach The authors conducted an online survey of the community of a regional comprehensive university in the St. Louis metro-east region (Illinois, USA). They analyzed 781 responses using mixed methods, and developed recommendations based on community-based social marketing principles. Findings Black respondents reported higher bottled water use than White respondents. Undergraduate students reported higher bottled water use than faculty or staff. Most respondents were concerned about cost and environmental impact for bottled water and taste and water quality for tap water. Chemical and safety concerns were specific and location-focused for tap water only. Concerns were similar to Safe Drinking Water Act mandated public information, such as prior reports of lead (Pb) in campus drinking water. Tap water taste concerns may relate to proximity to the water treatment plant, resulting in high residual chlorine levels. To increase tap water use in this community, the authors recommend persuasive information campaigns, improvements to infrastructure and distribution that increase tap water convenience, more transparent public reporting on tap water lead levels, management of residual chlorine levels, and establishment of institutional norms favoring tap water over bottled water. Originality/value The authors evaluate barriers to drinking tap water across multiple environmental and social systems. The methods used in this study combine mixed methods analysis and community-based social marketing. The findings integrate respondent demographics and concerns, local water quality, local and national contamination events, campus-specific sustainability initiatives and barriers, and national drinking water regulations.more » « less

University introductory computer science courses (CS1) present many challenges. Students enter CS1 with varying backgrounds and many are evaluating their potential for success in the major. Students often negatively self-assess in response to natural programming moments, such as getting a syntax error, but we have a limited understanding of the mechanisms that drive these self-assessments. In this paper, we study the differences in student assessments of themselves and their assessments of others in response to particular programming moments. We analyze survey data from 214 CS1 students, finding that many have a self-critical bias, evaluating themselves more harshly than others. We also found that women have a stronger self-critical bias, and that students tend to be more self-critical when the other is female. These insights can help us reduce the impact of negative self-assessments on student experiences.more » « less

Students often get stuck when programming independently, and need help to progress. Existing, automated feedback can help students progress, but it is unclear whether it ultimately leads to learning. We present Step Tutor, which helps struggling students during programming by presenting them with relevant, step-by-step examples. The goal of Step Tutor is to help students progress, and engage them in comparison, reflection, and learning. When a student requests help, Step Tutor adaptively selects an example to demonstrate the next meaningful step in the solution. It engages the student in comparing "before" and "after" code snapshots, and their corresponding visual output, and guides them to reflect on the changes. Step Tutor is a novel form of help that combines effective aspects of existing support features, such as hints and Worked Examples, to help students both progress and learn. To understand how students use Step Tutor, we asked nine undergraduate students to complete two programming tasks, with its help, and interviewed them about their experience. We present our qualitative analysis of students' experience, which shows us why and how they seek help from Step Tutor, and Step Tutor's affordances. These initial results suggest that students perceived that Step Tutor accomplished its goals of helping them to progress and learn.more » « less

null (Ed.)The precise quantification of Pb exposure from tap water can help water utilities and public health organizations assess and mitigate elevated Pb concentrations. Several sampling protocols have been developed for this purpose; however, each existing protocol has limitations associated with sampling time, sample sizes, and ease of application. This study confirmed the ability of point-of-use faucet filters to accumulate Pb and then developed an extraction method that can enable quantification of Pb exposure from tap water. Nearly all Pb from both real and synthetic tap water was accumulated on POU filters, and four different methods for extracting the accumulated Pb were evaluated. Approximately 100% Pb recovery was achieved with a single pass flow-through method using a nitric acid solution. This Pb exposure quantification method could potentially be applied to real drinking water systems to provide an effective indication of Pb exposure from tap water.more » « less
