Vacant lots. Historic buildings overgrown with weeds. Walls and alleyways covered with graffiti. These are sights associated with countless inner-city neighborhoods in America, and yet many viewers have trouble getting beyond the surface of such images, whether they are denigrating them as signs of a dangerous ghetto or romanticizing them as traits of a beautiful ruined landscape. The Street: A Field Guide to Inequality provides readers with the critical tools they need to go beyond such superficial interpretations of urban decay. Using MacArthur fellow Camilo José Vergara's intimate street photographs of Camden, New Jersey as reference points, the essays in this collection analyze these images within the context of troubled histories and misguided policies that have exacerbated racial and economic inequalities. Rather than blaming Camden's residents for the blighted urban landscape, the multidisciplinary array of scholars contributing to this guide reveal the oppressive structures and institutional failures that have led the city to this condition. Tackling topics such as race and law enforcement, gentrification, food deserts, urban aesthetics, credit markets, health care, childcare, and schooling, the contributors challenge conventional thinking about what we should observe when looking at neighborhoods.

This study aimed to evaluate the effect of a nutritional intervention involving a problem-raising approach and the use of pictorial representations on the promotion of knowledge and practices of healthy eating among adolescents. This randomized study included 461 adolescents from public schools in Brasilia, Federal District, Brazil (intervention group: 273 students from four schools; control group: 188 students from three schools). Mean age was 14.8±1.0, and 52.9% were boys. The intervention consisted of three meetings with interactive activities about principles of healthy eating, food classification, importance of reading labels and analyzing food advertising critically, and representations of healthy and unhealthy meals and their sugar, salt, and fat content. Pictorial materials consisted of food drawings, food models, and a food packaging model. Controls were not exposed to any activity. Dietary knowledge, consumption, and behaviors were the variables of interest. The intervention group showed a higher mean score of correct answers to questions about dietary knowledge than the control group (p = 0.0006), with higher odds of correctly answering questions about in natura (OR: 3.7; 95% CI: 1.9-6.6), minimally processed (OR: 3.6; 95% CI: 1.9-6.4), processed (OR: 2.2; 95% CI: 1.1-4.3), and ultra-processed foods (OR: 3.5; 95% CI: 1.8-6.6) and composition of ultra-processed foods (OR: 2.4; 95% CI: 1.3-4.4). Participants in the intervention group were also 2.5 times more likely to correctly answer questions about the importance of the dietary environment (95% CI: 1.1-5.5) and caution with food advertising (95% CI: 1.2-5.3) than controls. Increased weekly consumption of vegetables (p = 0.0077; OR: 2.4; 95% CI: 1.26-4.51) and reduced consumption of soft drinks (p = 0.0212; OR: 0.36; 95% CI: 0.15-0.86) were observed in the intervention group compared to the control group. The proposed intervention increased adolescents' knowledge and improved some of their dietary habits. Educational activities using a problem-raising approach and pictorial representations of food appear to be effective in promoting healthy eating practices among adolescents.

For over a decade, artist Jimmy Fike traveled across the continental United States in an epic effort to photograph wild edible flora. Edible Plants is the culmination of that journey, featuring over 100 photographs that Fike has selectively colorized to highlight the comestible part of the plant. While the images initially appear to be scientific illustrations or photograms from the dawn of photography when plants were placed directly on sensitized paper and exposed under the sun, a closer look reveals, according to Liesl Bradner of the Los Angeles Times , \"haunting [and] eerily beautiful\" photographs. Beyond instilling wonder, Fike's contemporary, place-based approach to landscape photography emphasizes our relationship to the natural world, reveals food sources, and encourages environmental stewardship. His clever and beautiful method makes it easy to identify both the specimen and its edible parts and includes detailed descriptions about the plant's wider purposes as food and medicine. Sumptuously illustrated and delightfully informative, Edible Plants is the perfect gift for anyone curious about unlocking the secrets of native North American plants.

We describe an integrated and straightforward new analytical protocol that identifies plant gums from various sample sources including cultural heritage. Our approach is based on the identification of saccharidic fingerprints using mass spectrometry following controlled enzymatic hydrolysis. We developed an enzyme cocktail suitable for plant gums of unknown composition. Distinctive MS profiles of gums such as arabic, cherry and locust-bean gums were successfully identified. A wide range of oligosaccharidic combinations of pentose, hexose, deoxyhexose and hexuronic acid were accurately identified in gum arabic whereas cherry and locust bean gums showed respectively Pent x Hex y and Hex n profiles. Optimized for low sample quantities, the analytical protocol was successfully applied to contemporary and historic samples including ‘Colour Box Charles Roberson & Co’ dating 1870s and drawings from the American painter Arthur Dove (1880–1946). This is the first time that a gum is accurately identified in a cultural heritage sample using structural information. Furthermore, this methodology is applicable to other domains (food, cosmetic, pharmaceutical, biomedical).

Background It is only recently that written sources of local knowledge on plants are not being ignored by scholars as not belonging to “traditional” knowledge. Ethnobotanical texts, however, if they at all focus on knowledge from written sources, hardly ever pay any attention to the actual processes of interaction with written texts and illustrations. During our research, we examined people’s interactions with texts, illustrations, and herbarium specimens of plants they collect or are familiar with. We focused on a small community of Shiri people in the mountainous village and in the lowland settlements in the Republic of Daghestan, Russia. In the paper, we address the following questions: how do Shiri people interact with illustrations, written text, and herbaria specimens? How is this interaction influenced by the practice of plant collection? What are the methodological implications of the ways people interact with illustrations, texts, and herbaria specimens? Methods Our research was based on long-term ethnographic fieldwork: co-designing of a booklet showing edible plants people collect in Shiri, semi-structured interviews, and video-recordings, and observing interactions between people and text/illustrations/voucher specimens. Results We identified three kinds of interactions between individuals and text/illustrations: “text-wayfaring”—predominantly a bodily interaction between an individual and illustrations and text; “fact/spelling checking”—predominantly discursive and information focused; “between wayfaring and fact-checking”—the mix of the two. Using the idea of textual poaching, as well as the knowledge-making approach, we show that the mode of interaction with text/illustrations influences what is acquired, and how. This process influences readers’ LEK. The mere presence of an information in the text available to people does not imply that they will acquire it, make use of it, and change their LEK. Photographs and pressed specimens of locally known plants are often not (or only partly) recognized by the interlocutors. Video-recording is essential for analyzing the above mentioned interactions. Conclusions In ethnobotanical research, it is important to pay more attention to people’s interaction with their sources of knowledge, including text and illustrations. The discursive part of LEK is more easily influenced by written sources. The practice of plant collection is not as easily influenced. Ethnobotanists function in a particular context and are embedded in discourses oriented towards conservation of bio-cultural diversity that value heritage as such, so it is important to be aware of one’s positionality. A methodology that relies on showing pressed specimens or photographs to interlocutors may be a very misleading way of collecting ethnobotanical data.

Purpose: This study tested whether behavioral mimicry can alter drinking behavior. It was hypothesized that participants would increase drinking behaviors given increased confederate drinking but not cup touching. Methods: Nineteen healthy adults (M[subscript age] = 20.32 years) completed 2 picture description tasks; during 1 task, a confederate frequently sipped water (\"complete\" drinking gesture), and during the other, the confederate touched her cup but did not drink (\"partial\" gesture). Outcome measures included number of drinks per minute, number of cup touches per minute, percentage of time spent drinking, and percentage of time spent touching the cup. Results: Participants spent more time drinking and had an increased drinking rate during the drinking condition versus the cup-touching condition. For a majority of participants, drinking rate increased during the drinking condition versus baseline. Drinking, but not cup touching, rate also increased given increased confederate cup touching for many. Conclusions: Mimicry likely contributes to social modeling of drinking behaviors. This effect appears more robust given a complete target gesture (full drink); however, a partial goal-directed drinking gesture may also yield a mimicked response. Beyond the theoretical implications, these results provide directions for research investigating more naturalistic mechanisms for increasing dietary intake in various patient populations (e.g., individuals with dysphagia).
