    Abstract To create new product opportunities for sorghum in the state of Kansas, the FARMUs project had three primary pillars: Innovate, Scale, and Connect. The project aims to close the gap between industry and consumers by peaking interest in sorghum, its nutritional and sustainable benefits, and consumption of sorghum-based products. The primary focus of this study was to develop and scale-up three gluten-free sorghum-based products for Kansas State Dining Services. The secondary objective was to evaluate the sensory and physical properties of these products to provide developmental and research experience for students. Preliminary testing involved identifying optimum ratios of sorghum flour, xanthan gum, starch, and eggs for proper binding. Whipped egg whites were tested at different levels for product volume and texture. Repetition and reformulation of the products provided various renditions of each product. Quantity equipment needs, staffing feasibility, ingredient availability, and cost were determined. Dining staff evaluated each product and once recipes were finalized, parameters (color, specific gravity, internal temperature, moisture loss, height/width, water activity) were evaluated. Dining center customers provided acceptability feedback for the three gluten-free products using the 9-point Hedonic scale. The first product, a savory waffle, can be stacked with turkey sausage and cheddar cheese for a breakfast sandwich. It utilizes sorghum flour, egg whites, xanthan gum, starch, and flaxseed for structure. This product received a range of 7.03–7.63 (n = 43) for all sensory attributes (acceptability, flavor, mouthfeel, texture, and aftertaste). The lemon blueberry muffin contains sorghum flour, eggs, buttermilk, xanthan gum, potato starch, and egg whites. Sensory data (n = 49) measured at acceptability (7.4), flavor (7.6), mouthfeel (6.4), texture (6.6), and aftertaste (7.6). The third product, a sweet potato muffin top, contains sorghum flour, xanthan gum, eggs, egg whites, and sweet potatoes. All three ...

    Abstract This article interprets the representation of the city in the Argentine film, The Aerial (2007) directed by Esteban Sapir. I argue that through the intertextual, surrealist and, at times, ludic relationship that this film maintains with works from cinema’s silent era, especially Fritz Lang’s Metropolis (1926), The Aerial criticizes the oppressive control imposed by contemporary multimedia companies and demands a resistance of this power that is represented as totalitarian. Since the 1990s, the globalized economy has led to the deregularization and the privatization of the media in Argentina. Under these conditions, possibilities for communication have diminished even though the number of television programs has expanded. While the recycling of images and classical techniques from the first eras of cinema serves to underscore the artificiality of the filmic, Sapir’s second feature length film critiques the omnipresence of the media in contemporary Latin America.

    Abstract The ability to regulate the intake of unhealthy foods is critical in modern, calorie dense food environments. Frontal areas of the brain, such as the dorsolateral prefrontal cortex (DLPFC), are thought to play a central role in cognitive control and emotional regulation. Therefore, increasing activity in the DLPFC may enhance these functions which could improve the ability to reappraise and resist consuming highly palatable but unhealthy foods. One technique for modifying brain activity is transcranial direct current stimulation (tDCS), a non-invasive technique for modulating neuronal excitability that can influence performance on a range of cognitive tasks. We tested whether anodal tDCS targeting the right DLPFC would influence how people perceived highly palatable foods. In the present study, 98 participants were randomly assigned to receive a single session of active tDCS (2.0 mA) or sham stimulation. While receiving active or sham stimulation, participants viewed images of highly palatable foods and reported how pleasant it would be to eat each food (liking) and how strong their urge was to eat each food (wanting). We found that participants who received active versus sham tDCS stimulation perceived food as less pleasant, but there was no difference in how strong their urge was to eat the foods. Our findings suggest that modulating excitability in the DLPFC influences “liking” but not “wanting” of highly palatable foods. Non-invasive brain stimulation might be a useful technique for influencing the hedonic experience of eating but more work is needed to understand when and how it influences food cravings.

    Abstract The cognitive bias model of animal welfare assessment is informed by studies with humans demonstrating that the interaction between emotion and cognition can be detected using laboratory tasks. A limitation of cognitive bias tasks is the amount of training required by animals prior to testing. A potential solution is to use biologically relevant stimuli that trigger innate emotional responses. Here; we develop a new method to assess emotion in rhesus macaques; informed by paradigms used with humans: emotional Stroop; visual cueing and; in particular; response slowing. In humans; performance on a simple cognitive task can become impaired when emotional distractor content is displayed. Importantly; responses become slower in anxious individuals in the presence of mild threat; a pattern not seen in non-anxious individuals; who are able to effectively process and disengage from the distractor. Here; we present a proof-of-concept study; demonstrating that rhesus macaques show slowing of responses in a simple touch-screen task when emotional content is introduced; but only when they had recently experienced a presumably stressful veterinary inspection. Our results indicate the presence of a subtle “cognitive freeze” response; the measurement of which may provide a means of identifying negative shifts in emotion in animals.

    Abstract There has been increased recognition of the 3Rs in laboratory animal management over the last decade, including improvements in animal handling and housing. For example, positive reinforcement is now more widely used to encourage primates to cooperate with husbandry procedures, and improved enclosure design allows housing in social groups with opportunity to escape and avoid other primates and humans. Both practices have become gold standards in captive primate care resulting in improved health and behavioural outcomes. However, training individuals and social housing may be perceived as incompatible, and so it is important to share protocols, their outcomes and suggestions for planning and improvements for future uptake. Here we present a protocol with link to video for training rhesus macaques (Macaca mulatta) housed in single-male – multi-female breeding groups to sit at individual stations in the social enclosure. Our aim was that the monkeys could take part in welfare-related cognitive assessments without the need for removal from the group or interference by group members. To do this we required most individuals in a group to sit by individual stations at the same time. Most of the training was conducted by a single trainer with occasional assistance from a second trainer depending on availability. We successfully trained 61/65 monkeys housed in groups of up to nine adults (plus infants and juveniles) to sit by their individual stationing tools for >30s. Males successfully trained on average within 30min (2 training sessions); females trained on average in 1h 52min±13min (7.44 sessions), with rank (high, mid, low) affecting the number of sessions required. On average, dominant females trained in 1h 26min±16min (5.7 sessions), mid ranked females in 1h 52min±20min (7.45 sessions), and subordinate females took 2h 44min±36min (10.9 sessions). Age, group size, reproductive status, temperament, and early maternal separation did not influence the number of sessions a monkey required to reach criterion. We hope this protocol will be useful for facilities worldwide looking to house their animals in naturalistic social groups without impacting on animal husbandry and management.

  6. Article ; Online: Evidence that emotion mediates social attention in rhesus macaques.

    Abstract BACKGROUND: Recent work on non-human primates indicates that the allocation of social attention is mediated by characteristics of the attending animal, such as social status and genotype, as well as by the value of the target to which attention is directed. Studies of humans indicate that an individual's emotion state also plays a crucial role in mediating their social attention; for example, individuals look for longer towards aggressive faces when they are feeling more anxious, and this bias leads to increased negative arousal and distraction from other ongoing tasks. To our knowledge, no studies have tested for an effect of emotion state on allocation of social attention in any non-human species. METHODOLOGY: We presented captive adult male rhesus macaques with pairs of adult male conspecific face images - one with an aggressive expression, one with a neutral expression - and recorded gaze towards these images. Each animal was tested twice, once during a putatively stressful condition (i.e. following a veterinary health check), and once during a neutral (or potentially positive) condition (i.e. a period of environmental enrichment). Initial analyses revealed that behavioural indicators of anxiety and stress were significantly higher after the health check than during enrichment, indicating that the former caused a negative shift in emotional state. PRINCIPLE FINDINGS: The macaques showed initial vigilance for aggressive faces across both conditions, but subsequent responses differed between conditions. Following the health check, initial vigilance was followed by rapid and sustained avoidance of aggressive faces. By contrast, during the period of enrichment, the macaques showed sustained attention towards the same aggressive faces. CONCLUSIONS/SIGNIFICANCE: These data provide, to our knowledge, the first evidence that shifts in emotion state mediate social attention towards and away from facial cues of emotion in a non-human animal. This work provides novel insights into the evolution of emotion-attention interactions in humans, and mechanisms of social behaviour in non-human primates, and may have important implications for understanding animal psychological wellbeing.

    Abstract Previous research has demonstrated that route planners use several reliable strategies for selecting between alternate routes. Strategies include selecting straight rather than winding routes leaving an origin, selecting generally south- rather than north-going routes, and selecting routes that avoid traversal of complex topography. The contribution of this paper is characterizing the relative influence and potential interactions of these strategies. We also examine whether individual differences would predict any strategy reliance. Results showed evidence for independent and additive influences of all three strategies, with a strong influence of topography and initial segment straightness, and relatively weak influence of cardinal direction. Additively, routes were also disproportionately selected when they traversed relatively flat regions, had relatively straight initial segments, and went generally south rather than north. Two individual differences, extraversion and sense of direction, predicted the extent of some effects. Under real-world conditions navigators indeed consider a route's initial straightness, cardinal direction, and topography, but these cues differ in relative influence and vary in their application across individuals.
