Work by Chomsky et al. (2019) and Epstein et al. (2018) develops a third-factor principle of computational efficiency called “Determinacy”, which rules out “ambiguous” syntactic rule-applications by requiring one-to-one correspondences between the input or output of a rule and a single term in the domain of that rule. This article first adopts the concept of “Input Determinacy” articulated by Goto and Ishii (2019, 2020), who apply Determinacy specifically to the input of operations like Merge, and then proposes to extend Determinacy to the labeling procedure developed by Chomsky (2013, 2015). In particular, Input Determinacy can explain restrictions on labeling in contexts where multiple potential labels are available (labeling ambiguity), and it can also provide an explanation for Chomsky's (2013, 2015) proposal that syntactic movement of an item (“Internal Merge”) renders that item invisible to the labeling procedure.

Discussions of terrorism assume actual or threatened violence, but the term is regularly used to delegitimize rivals' nonviolent actions. Yet do ordinary citizens accept descriptions of nonviolence as terrorism? Using a preregistered survey-experiment in Israel, a salient conflictual context with diverse repertoires of contention, we find that audiences rate adversary nonviolence close to terrorism, consider it illegitimate, and justify its forceful repression. These perceptions vary by the action's threatened harm, its salience, and respondents' ideology. Explicitly labeling nonviolence as terrorism, moreover, particularly sways middle-of-the-road centrists. These relationships replicate in a lower-salience conflict, albeit with milder absolute judgments, indicating generalizability. Hence, popular perceptions of terrorism are more fluid and manipulable than assumed, potentially undermining the positive effects associated with nonviolent campaigns.

In January 2020, the United States implemented a federal bioengineered labeling standard for food products that contain genetically modified material set to go into effect in January 2022. This bioengineered label indicates which products contain detectable levels of genetic material that have been modified through lab techniques that cannot be achieved in nature. An already existing alternative to the bioengineered label is the Non-GMO Project verified label which has been on the market since 2007, and indicates products free of genetically modified material through lab techniques. As consumers are now confronted with multiple labels pertaining to information related to genetic engineering, it is important to understand how people interpret these labels as it can lead to a greater understanding of how they inform consumer choice. We conducted a survey with 153 biology and environmental studies undergraduate students at Binghamton University in Binghamton, New York, asking questions about participants' views on genetically modified organisms (GMOs) and related terminology, corresponding food labels and how these labels influence their purchasing decisions. Results demonstrated a lack of awareness of the bioengineered label compared to the Non-GMO Project verified label. Additionally, individuals associated ‘bioengineered’ and ‘genetically modified’ with differing themes, where ‘bioengineered’ was more often associated with a scientific theme and ‘genetically modified’ was more often associated with an agricultural theme. There was also a discrepancy in how individuals said these labels influenced their purchases vs how the labels actually influenced purchasing decisions when participating in choice experiments. While the majority of participants reported that neither the Non-GMO Project verified label nor the bioengineered label influenced their purchasing decisions, in choice experiments, the majority of respondents chose products with the Non-GMO Project verified label. This study can give insight into overall perceptions of different terminologies associated with genetic engineering, in addition to how these labels are interpreted by consumers, and how they could affect purchasing decisions with the implementation of the new bioengineered label.

This article uses meta-regression analysis to examine variation in willingness to pay (WTP) for farm-raised seafood and aquaculture products. We measure the WTP premiums that consumers have for common product attributes and examine how WTP varies systematically across study design elements, populations of interest, and sample characteristics. Based on metadata from 45 studies, the meta-regression analysis indicates that WTP estimates differ significantly with the availability of attributes such as domestic and environmental certification, but also with sample income and gender representation.

The First Amendment to the US Constitution protects commercial speech from government interference. Commercial speech has been defined by the US Supreme Court as speech that proposes a commercial transaction, such as marketing and labeling. Companies that produce products associated with public health harms, such as alcohol, tobacco, and food, thus have a constitutional right to market these products to consumers. This article will examine the evolution of US law related to the protection of commercial speech, often at the expense of public health. It will then identify outstanding questions related to the commercial speech doctrine and the few remaining avenues available in the United States to regulate commercial speech including the use of government speech and addressing deceptive and misleading commercial speech.

Partial equilibrium models have been used extensively by policy makers to prospectively determine the consequences of government programs that affect consumer incomes or the prices consumers pay. However, these models have not previously been used to analyze government programs that inform consumers. In this paper, we develop a model that policy makers can use to quantitatively predict how consumers will respond to risk communications that contain new health information. The model combines Bayesian learning with the utility-maximization of consumer choice. We discuss how this model can be used to evaluate information policies; we then test the model by simulating the impacts of the North Dakota Folic Acid Educational Campaign as a validation exercise.

Understanding biofilm interactions with surrounding substratum and pollutants/particles can benefit from the application of existing microscopy tools. Using the example of biofilm interactions with zero-valent iron nanoparticles (nZVI), this study aims to apply various approaches in biofilm preparation and labeling for fluorescent or electron microscopy and energy dispersive X-ray spectrometry (EDS) microanalysis for accurate observations. According to the targeted microscopy method, biofilms were sampled as flocs or attached biofilm, submitted to labeling using 4’,6-diamidino-2-phenylindol, lectins PNA and ConA coupled to fluorescent dye or gold nanoparticles, and prepared for observation (fixation, cross-section, freezing, ultramicrotomy). Fluorescent microscopy revealed that nZVI were embedded in the biofilm structure as aggregates but the resolution was insufficient to observe individual nZVI. Cryo-scanning electron microscopy (SEM) observations showed nZVI aggregates close to bacteria, but it was not possible to confirm direct interactions between nZVI and cell membranes. Scanning transmission electron microscopy in the SEM (STEM-in-SEM) showed that nZVI aggregates could enter the biofilm to a depth of 7–11 µm. Bacteria were surrounded by a ring of extracellular polymeric substances (EPS) preventing direct nZVI/membrane interactions. STEM/EDS mapping revealed a co-localization of nZVI aggregates with lectins suggesting a potential role of EPS in nZVI embedding. Thus, the combination of divergent microscopy approaches is a good approach to better understand and characterize biofilm/metal interactions.

This paper investigates the state of pork supply as to its neglect of developing innovations and mechanisms for delivering superior eating quality to consumers. We explore reasons behind pork supply chains’ predominant focus on mass production combined with traceability and food safety, while only little attention has been given to potentially lucrative niche markets focused on intrinsic quality cues. Using established analytical frameworks of hedonic pricing and transactions costs economics we discuss alternative strategies for the segregation and promotion of intrinsic sensory differentiated pork. Growing empirical evidence in the literature underpins the importance of eating experience in delivering utility to consumers and in stabilizing declining demand trends in major markets. Building on current consumer behavioral literature and organizational developments in meat supply chains in Europe and Australia, we critically discuss opportunities to overcome this supposedly suboptimal situation.

We administered an online choice experiment to a sample of U.S. raw-oyster consumers to identify factors influencing preferences for Gulf of Mexico oysters, determined the extent of preference heterogeneity, and estimated marginal willingness to pay for specific varieties and other key attributes. Results indicate significant preference heterogeneity among select varieties, with non-Gulf respondents estimated to require a price discount on Gulf oyster varieties on the order of $3–$6/half dozen. Gulf respondents were found to be less sensitive to oyster variety, and estimated to be willing to pay a price premium only for select Gulf varieties on the order of $0–$3/half dozen.

Government mandates to disclose information are a standard response to problems of asymmetric information. We examine recent major U.S. regulations issued between 2008 and 2013 to identify disclosure mandates and look for quantitative assessments of their effectiveness in improving comprehension. We also reviewed the retrospective regulatory review reports of four federal agencies – prepared pursuant to Executive Orders 13563 and 13579 – for analyses of existing mandates. We find that although mandated disclosures underpin a number of major federal regulatory initiatives, agencies infrequently issue such mandates based on scientifically valid, controlled studies of the improvements in comprehension from such disclosure. We also conduct four case studies drawn from the relatively few instances where federal agencies have evaluated improvements in comprehension, to identify current best practices. Finally, we recommend reforms to improve federally mandated information disclosure.

Conjoint analysis is used to measure the preferences of United States consumers for labeling of biotech foods. The study found that consumers in the sample support mandatory labeling of biotech foods. This suggests that U.S. consumers would support revisions to the present voluntary labeling policy of the U.S. Food and Drug Administration and the U.S. Department of Agriculture. Results also showed that the preferred labeling format is a text disclosure that describes the benefits of biotechnology in combination with a biotech logo.
