A metric of team multitasking throughput.

We developed a novel, unobtrusive estimate of team multitasking throughput (tMT). We demonstrate it through the quantitative assessment of tMT in distributed dyads when objective performance and purported reliability are manipulated among teammates. In a within-subjects experiment, we investigated the effects of teammates' performance and purported reliability on tMT.

Sustainability considerations are not influencing meat consumption in the US.

The consumption of animal-source foods, and particularly red meat from ruminants, is a major contributor to greenhouse gas emissions, freshwater use, and loss of biodiversity. Reducing red meat consumption has been identified as a key strategy to mitigate climate change; however, little is known about how to effectively intervene to promote its reduction in the United States (US). This study aimed to examine meat (red, unprocessed, and poultry) and seafood consumption patterns, the factors influencing their consumption (including a reduction in their consumption over time), and how these differed based on socioeconomic variables.

An extension of the shifted Wald model of human response times: Capturing the time dynamic properties of human cognition : Trial-varying Wald model.

Despite the ubiquitous nature of evidence accumulation models in cognitive and experimental psychology, there has been a comparatively limited uptake of such techniques in the applied literature. While quantifying latent cognitive processing properties has significant potential for applied domains such as adaptive work systems, accumulator models often fall short in practical applications. Two primary reasons for these shortcomings are the complexities and time needed for the application of cognitive models, and the failure of current models to capture systematic trial-to-trial variability in parameters.

Predictions of task using neural modeling.

Introduction: A well-designed brain-computer interface (BCI) can make accurate and reliable predictions of a user's state through the passive assessment of their brain activity; in turn, BCI can inform an adaptive system (such as artificial intelligence, or AI) to intelligently and optimally aid the user to maximize the human-machine team (HMT) performance. Various groupings of spectro-temporal neural features have shown to predict the same underlying cognitive state (e.g.

Food Environments and Their Influence on Food Choices: A Case Study in Informal Settlements in Nairobi, Kenya.

The food environments that people have access to shape their food choices. The purpose of this study was to use mixed methods to characterize the external food environment in informal settlements in Nairobi, Kenya and to examine the individual factors that influence the way in which women interact with those environments to make food choices. We used a combination of food environment assessments (vendor mapping, collection of food prices, food quality assessments) and five focus group discussions with women ( = 26) in four villages within two informal settlements in Nairobi (Mukuru and Kibera) to better understand the drivers of food choice.

Drivers of food choice among women living in informal settlements in Nairobi, Kenya.

Suboptimal diets drive the multiple burdens of malnutrition among women living in informal settlements. Women's food choices have important implications for their health, as well as that of their families. The purpose of this study was to examine how food choice decisions might differ across different age groups of women living in informal settlements in Nairobi, Kenya.

A focused ethnographic study on the role of health and sustainability in food choice decisions.

In the United States, typical dietary patterns are not necessarily healthy and sustainable. In order to shift diets, we need to provide support to individuals in a way that reflects what matters most to them. In this study, we aimed to identify the considerations that are most important to individuals regarding food-related decisions, and to determine how those considerations relate to specific foods, with a focus on health and environmental sustainability.

Derivation and Demonstration of a New Metric for Multitasking Performance.

Objective: We proposed and demonstrate a theory-driven, quantitative, individual-level estimate of the degree to which cognitive processes are degraded or enhanced when multiple tasks are simultaneously completed.

Background: To evaluate multitasking, we used a performance-based cognitive model to predict efficient performance. The model controls for single-task performance at the individual level and does not depend on parametric assumptions, such as normality, which do not apply to many performance evaluations.

Why Marginalization, Not Vulnerability, Can Best Identify People in Need of Special Medical and Nutrition Care.

In a 2015 paper published in the , bioethicist Henk ten Have identifies vulnerability as a "controversial topic in bioethics" and argues that bioethical attention to vulnerability comes at the expense of sufficient attention to the social structures that shape human life. In this paper, we situate ten Have's argument within the broader bioethical literature, emphasizing how critiques of vulnerability can enrich approaches in clinical settings, including in nutrition, where the concept of vulnerability is not foreign (eg, children are often labeled members of a vulnerable group). We use an example of food (in)security to show how reframing vulnerability to capture "layers of marginalization" can help clinicians and organizations more clearly identify who is most in need, develop solutions for what should be done, and determine how and by whom those solutions should be implemented.

Capturing Changes in HIV-Infected Breastfeeding Mothers' Cognitive Processes from Before Delivery to 5 Months Postpartum: An Application of the Pile-Sorting Technique in Haiti.

Background: The cognitive processes involved in individuals' perceptions and prioritization of information, and how these change with experience or exposure to interventions, are rarely examined in the evaluation of nutrition interventions. Exclusive breastfeeding counseling is a common infant and young-child feeding intervention and is used to promote HIV-free survival in the prevention of mother-to-child transmission programs. However, it is often designed without adequate attention to the changes in mothers' perceptions over the course of their early breastfeeding experiences.

Who knows what: An exploration of the infant feeding message environment and intracultural differences in Port-au-Prince, Haiti.

Worldwide, mothers with young children receive many messages about infant feeding. Some messages are generated by health providers and others by the households, communities, and social contexts in which women live. We aimed to determine the scope of infant feeding messages in urban Haiti and to examine intracultural differences in salience of these messages and their alignment with international guidelines.

The perceptual processing of fused multi-spectral imagery.

Multi-spectral imagery can enhance decision-making by supplying multiple complementary sources of information. However, overloading an observer with information can deter decision-making. Hence, it is critical to assess multi-spectral image displays using human performance.
