When Communities Face Drinking Water Crises, Bottled Water is a \u27Temporary\u27 Solution That Often Lasts Years--and Worsens Inequality

As a sociologist, I study the social and environmental effects of the rapid growth of bottled-water consumption in the U.S. and beyond, and how it is linked to distrust of public tap water. In my new book, “Unbottled,” one chapter examines how these dynamics played out in Flint. As its example shows, communities can end up relying on bottled water – often at great expense – for years after a crisis

Unequal Trust: Bottled Water Consumption, Distrust In Tap Water, and Economic and Racial Inequality In the United States

Reviewing public health, nutrition, and social science literature, this article examines how bottled water consumption and spending in the United States differ along lines of race, ethnicity, and income, how these consumption patterns have changed in recent years, and how those shifts map onto perceptions of the safety and trustworthiness of tap water supplies, both before and since the Flint water disaster. It also addresses the differential impact of bottled water spending on household income. The findings challenge the truism that bottled water consumption is positively correlated with income, instead showing a bimodal racial and class consumption pattern that reflects widely divergent perceptions—and the uneven distribution—of threats to tap water safety. Bottled water consumption and spending, as well as distrust of tap water, are highest among low-income, Black, and Latino/a households, exacerbating social inequality. The article also addresses how the bottled water industry is responding to these dynamics, and considers potential routes to restoring both public water infrastructure and trust in tap water supplies. This contribution links several current and salient topics: the relationship between bottled water\u27s growth and tap water consumption; the dynamics of growing racial and income inequality; historical legacies of systemic racism and economic marginalization; and the uneven effects of disinvestment in US water infrastructure on tap water safety, access, and affordability

A More Perfect Commodity: Bottled Water, Global Accumulation, and Local Contestation

Bottled water sits at the intersection of debates regarding the social and environmental effects of the commodification of nature and the ways neoliberal globalization alters the provision of public services. Utilizing Polanyi\u27s concept of fictitious commodities and Harvey\u27s work on accumulation by dispossession, this article traces bottled water\u27s transformation from elite niche item to a product consumed by three fourths of U.S. households. Drawing on ethnographic research with participants in two cases of proposed spring water extraction from rural communities by industry leader Nestlé Waters, we make two principal arguments. First, the case of bottled water necessitates a reevaluation of existing theoretical frameworks regarding water privatization and commodification. Municipal tap water networks pose substantial barriers to capital accumulation, leading one influential scholar to frame water as an “uncooperative commodity.” However, bottled water\u27s characteristics enable it to evade many of these constraints, rendering it a “more perfect commodity” for accumulation. Second, expansion of the market good of bottled water alters the prospects for the largely publicly provided good of tap water. We conclude that the growth of this relatively new commodity represents a more serious threat to the project of universal public drinking water provision than that posed by tap water privatization

Tensions Between Firm Size and Sustainability Goals: Fair Trade Coffee in the United States

Sustainability marketing trends have typically been led by smaller, more mission-driven firms, but are increasingly attracting larger, more profit-driven firms. Studying the strategies of firms that are moving away from these two poles (i.e., mission-driven but larger firms, and profit-driven firms that are more committed to sustainability) may help us to better understand the potential to resolve tensions between firm size and sustainability goals. We used this approach to analyze a case study of the U.S. fair trade coffee industry, employing the methods of data visualization and media content analysis. We identified three firms that account for the highest proportion of U.S. fair trade coffee purchases (Equal Exchange, Green Mountain Coffee Roasters and Starbucks) and analyzed their strategies, including reactions to recent changes in U.S. fair trade standards. We found an inverse relationship between firm size and demonstrated commitment to sustainability ideals, and the two larger firms were much less likely to acknowledge conflicts between size and sustainability in their public discourse. We conclude that similar efforts to increase sustainability marketing for other products and services should be more skeptical of approaches that rely on primarily on the participation of large, profit-driven firms

Who’s the Fairest of Them All? The Fractured Landscape of U.S. Fair Trade Certification

In recent years, consumers in the United States have been confronted by no fewer than four competing fair-trade labels, each grounded in a separate certification system and widely differing standards. This fracturing is partly a response to the recent split by the U.S. certifier Fair Trade USA from the international fair trade system, but also illustrates longstanding divisions within the fair trade movement. This article explores the dynamics of competition among nonstate standards through content analyses of fair trade standards documents from the four U.S. fair-trade certifications for agrifood products (Fair Trade USA, Fairtrade America, Fair for Life, and the Small Producer Symbol). It analyzes the differences among them, asking what kinds of social and labor relations are facilitated by each, and identifies how closely they correspond with key fair trade principles. We make two primary arguments. First, we contend that the case of fair trade challenges the dominant conceptual model used to analyze competition among multiple private standards in a single arena, in which newer challengers lower the rigor of standards. Second, we argue that the current fractured U.S. certification landscape illuminates divisions among different interest groups over which principles—and which labor and production forms—should be privileged under the banner of fair trade

Economic Impacts of Montgomery County’s Parks

Final project for ENSP400: Capstone in Environmental Science (Fall 2017). University of Maryland, College Park.This project’s goal is to analyze how the presence and quality of local parks and open spaces affects adjacent property values and the local economy, and to gauge the public perception of parks in Montgomery County to better understand public opinion and concerns surrounding parks. This project will also recommend how those concerns can be addressed to make stakeholder groups more likely to support the activities of the County’s Department of Parks. We assessed opinions of property owners, businesses, developers, and residents in Montgomery County and beyond through on-line and in person surveys. Respondents were asked to assess park amenities by personal preference, state their willingness to pay a premium to live and work near a public park, and share other information on their perceptions of public green spaces in their area. Using these survey result as well as literature reviews, we found a trend of increasing property values near parks, a perception of increasing business activity due to the presence of parks, and an increased attraction of visitors and residents to an area because of parks. We also determined that parks benefit the natural ecosystem in a way that offers significant monetary value and that can benefit the local economy in the form of saved public utility costs and personal health benefits. The surveys also provided information on trends in public opinion about parks. The most favored park amenity was paved trails, while the least favored amenity was skateparks. Overall, respondents’ opinions were quite positive and any concerns they had were related to safety in parks. Our research and surveys enabled us to determine four distinct recommendations for the Department of Parks. The first is to implement popular amenities. The surveys showed that paved trails were the most popular amenity, followed by family-oriented activities and dog parks, and these amenities can greatly help to generate a more positive perception of parks. The second recommendation is to create educational programs to help people better understand the economic and social benefits parks can provide, especially their benefits to the natural ecosystem. When people better understand those benefits, they will be less likely to oppose new park plans. The third recommendation is to continue to develop a safe atmosphere within parks. One of the main concerns is that parks can foster crime, so if the Department of Parks were to heavily advertise their safety measures, such as displaying signs about security camera systems or advertising that the parks are under constant surveillance, people may feel safer and be less concerned about a park in their neighborhood. Finally, more surveys should be conducted. By continuing to survey the public’s perception of their parks, the Department will be able to tailor services to residents and visitors as preferences and demographics change. We believe that following these suggestions will increase the economic benefits of parks in Montgomery County.Montgomery Count

Mesothelin-specific CD8+ T Cell Responses Provide Evidence of In Vivo Cross-Priming by Antigen-Presenting Cells in Vaccinated Pancreatic Cancer Patients

Tumor-specific CD8+ T cells can potentially be activated by two distinct mechanisms of major histocompatibility complex class I–restricted antigen presentation as follows: direct presentation by tumor cells themselves or indirect presentation by professional antigen-presenting cells (APCs). However, controversy still exists as to whether indirect presentation (the cross-priming mechanism) can contribute to effective in vivo priming of tumor-specific CD8+ T cells that are capable of eradicating cancer in patients. A clinical trial of vaccination with granulocyte macrophage–colony stimulating factor–transduced pancreatic cancer lines was designed to test whether cross-presentation by locally recruited APCs can activate pancreatic tumor-specific CD8+ T cells. Previously, we reported postvaccination delayed-type hypersensitivity (DTH) responses to autologous tumor in 3 out of 14 treated patients. Mesothelin is an antigen demonstrated previously by gene expression profiling to be up-regulated in most pancreatic cancers. We report here the consistent induction of CD8+ T cell responses to multiple HLA-A2, A3, and A24-restricted mesothelin epitopes exclusively in the three patients with vaccine-induced DTH responses. Importantly, neither of the vaccinating pancreatic cancer cell lines expressed HLA-A2, A3, or A24. These results provide the first direct evidence that CD8 T cell responses can be generated via cross-presentation by an immunotherapy approach designed to recruit APCs to the vaccination site

Tyrosine 23 Phosphorylation-Dependent Cell-Surface Localization of Annexin A2 Is Required for Invasion and Metastases of Pancreatic Cancer

The aggressiveness of pancreatic ductal adenocarcinoma (PDA) is characterized by its high metastatic potential and lack of effective therapies, which is the result of a lack of understanding of the mechanisms involved in promoting PDA metastases. We identified Annexin A2 (ANXA2), a member of the Annexin family of calcium-dependent phospholipid binding proteins, as a new molecule that promotes PDA invasion and metastases. We found ANXA2 to be a PDA-associated antigen recognized by post-treatment sera of patients who demonstrated prolonged survival following treatment with a PDA-specific vaccine. Cell surface ANXA2 increases with PDA development and progression. Knockdown of ANXA2 expression by RNA interference or blocking with anti-ANXA2 antibodies inhibits in vitro invasion of PDA cells. In addition, post-vaccination patient sera inhibits in vitro invasion of PDA cells, suggesting that therapeutic anti-ANXA2 antibodies are induced by the vaccine. Furthermore, cell-surface localization of ANXA2 is tyrosine 23 phosphorylation-dependent; and tyrosine 23 phosphorylation is required for PDA invasion. We demonstrated that tyrosine 23 phosphorylation resulting in surface expression of ANXA2 is required for TGFβ-induced, Rho-mediated epithelial-mesenchymal transition (EMT), linking the cellular function of ANXA2 which was previously shown to be associated with small GTPase-regulated cytoskeletal rearrangements, to the EMT process in PDA. Finally, using mouse PDA models, we showed that shRNA knock-down of ANXA2, a mutation at tyrosine 23, or anti-ANXA2 antibodies, inhibit PDA metastases and prolong mouse survival. Thus, ANXA2 is part of a novel molecular pathway underlying PDA metastases and a new target for development of PDA therapeutics

General Education Learning Outcomes and Demographic Correlates in University Students in Hong Kong

Although there are studies showing that higher education would benefit university students, empirical research that comprehensively assesses student general education learning outcomes and related demographic correlates based on longitudinal data is minimal, especially in the Chinese context. To address the research gaps, the present study was conducted to investigate learning outcomes amongst university students in one university in Hong Kong based on a four-year longitudinal design (N = 460). Four dimensions of student general education learning outcomes were measured, including effective reasoning and problem solving, leadership, moral character, and integration of learning. Results suggested a U-shaped pattern of student learning outcomes for most dimensions, with no improvement or even a decrement in the second year and a steady growth thereafter. While family background did not affect student development, gender showed a significant moderating effect on students’ development in two dimensions (i.e., effective reasoning and problem solving, and integration of learning). These findings suggest that students benefit from general education-embedded university study in multiple dimensions, especially after the first year of transition period. Practical implications of the findings and future research directions were also discussed
