The current paper explores the impact that an augmented reality shopping assistant may have on consumers’ emotional and cognitive responses, and how it would affect their buying behaviours. A prototype of an application to assist consumers inside a supermarket was developed using HoloLens glasses. A total of 85 participants were invited to walk-through the store using augmented reality glasses. A PLS-SEM approach was used to test the conceptual model. Results using different scenarios show that media richness (the level of information cues, variety and immediate feedback) impacts consumer decisions and heightens their cognitive and emotional responses. The current study finds that a media-rich augmented reality experience influences brand engagement and willingness to buy through perceived information quality and brand attitudes. At a time when managers in every industry work to capture consumers’ attention, the present study shows how content remains important in every communication activity, even in an innovative augmented reality retail shopping experience. info:eu-repo/semantics/acceptedVersion

Objectives: We examined the association between obesity and early-onset cryptogenic ischemic stroke (CIS) and whether fat distribution or sex altered this association. Materials and Methods: This prospective, multi-center, case-control study included 345 patients, aged 18-49 years, with first-ever, acute CIS. The control group included 345 age- and sex-matched stroke-free individuals. We measured height, weight, waist circumference, and hip circumference. Obesity metrics analyzed included body mass index (BMI), waist-to-hip ratio (WHR), waist-to-stature ratio (WSR), and a body shape index (ABSI). Models were adjusted for age, level of education, vascular risk factors, and migraine with aura. Results: After adjusting for demographics, vascular risk factors, and migraine with aura, the highest tertile of WHR was associated with CIS (OR for highest versus lowest WHR tertile 2.81, 95%CI 1.43-5.51; P=0.003). In sex-specific analyses, WHR tertiles were not associated with CIS. However, using WHO WHR cutoff values (>0.85 for women, >0.90 for men), abdominally obese women were at increased risk of CIS (OR 2.09, 95%CI 1.02-4.27; P=0.045). After adjusting for confounders, WC, BMI, WSR, or ABSI were not associated with CIS. Conclusions: Abdominal obesity measured with WHR was an independent risk factor for CIS in young adults after rigorous adjustment for concomitant risk factors. © 2022 The Author(s)

In central Brazil, there are strong gradients and discontinuities in vegetation structure and composition between the forests of southern Amazonia and the open savannas of South America's Cerrado. These transitions are often controlled by disturbance processes, and the ability of vegetation to respond to climatic and environmental changes may depend on the regeneration traits of the different floras present. In this study we aim to assess the regeneration traits of tree communities of the Amazon-Cerrado transition and to understand how they differ among and within the markedly different vegetation types. We sampled 39 one-hectare long-term monitoring plots that include typical cerrado (TC = 10), cerradão (CD = 3), gallery forests (GF = 3), floodplain forests (FF = 6), seasonal and open rainforests (SF = 17). The regeneration traits assessed included dispersal syndrome (zoochory, anemochory, and autochory), fruit consistency (dry and fleshy), number of seeds per fruit, and diaspore dimensions (width and length). We found differences among the vegetation types, in all regeneration traits. These tended to be aggregate by vegetation structure, being similar for cerrado and cerradão species, and similar for SF, FF and GF (more forested vegetation). Vegetation types did not differ in functional diversity, however, while regeneration traits among seasonal and open rainforests were well-dispersed, in floodplain forests they were more clustered. Tree species depend substantially on fauna (zoochoric species between 42 and 86% in vegetation) for the dispersal across all habitats. By considering regeneration traits in the study of tree recruitment and establishment, we will increase our understanding about the dynamics of tree communities in neotropical forests and savannas.

The goal of this study was to compare the growth performance of growing/finishing pigs housed in a hoop barn system and in traditional confinement. A total of twenty B?saro breed pigs, with 98.6?5.71 days of age, and 25.4?4.87 kg of BW were used (beginning of experiment). The pigs were equally distributed in two groups: Gr1 ? hoop barn (3.0 m2/pig) with outdoor access (200 m2/pig); and Gr2 - traditional confinement with straw bedding (1.8 m2/pig). Both groups were fed with the same diet. During the next 98 days? period (growing phase) and until pigs reached approximately 80 kg LW, the animals were fed with a concentrate diet. In the finishing phase consisting of a final 70 days period until slaughter, the animals reached between 110-120 kg LW and were fed with concentrate and cornflour. The feed intake per group was registered daily and growth performances were collected every two weeks. During the growing phase no differences (P > 0.05) were observed in the average daily gain (ADG) between Gr1 (0.546?0.10 kg/day) and Gr2 (0.563?0.05 kg/day). However, a higher variability was observed in hoop barn group (CV of 18.1% vs. 8.8% in confinement). Similar results were observed during the finishing phase with ADG of 0.535?0.09 kg for Gr1 and 0.505?0.07 kg for Gr2 (P > 0.05). In both growing and finishing phases, the feed conversion rates (FCR) were 3.11 on the Gr1 versus 3.12 kg/kg on the Gr2, and 3.44 in Gr1 versus 3.53 in Gr2, respectively. Despite the different housing systems, ADG and FCR per period were identical in both systems. To the consumer's point of view, the positive aspects of the hoop barn system, such as the use of uncultivated land, product image and pig welfare, are sustainably attractive and therefore could be further reflected in the market.

Para tanto, foi realizado um planejamento fatorial com três parâmetros de síntese: temperatura, tempo e concentração de Cu2+, variando em dois níveis (mínimo e máximo), resultando em uma análise combinatória, em que cada experimento consistiu em uma configuração diferente dos fatores em seus respectivos níveis, o que levou a uma batelada de 23 = 8 experiências, para cada contraíon. Foram também realizadas sínteses com valores médios de cada parâmetro de reação, totalizando 9 sínteses para cada contraíon. O rendimento do produto da reação foi a variável resposta do planejamento fatorial. Os produtos foram caracterizados por espectroscopia de absorção vibracional na região do infravermelho, análise termogravimétrica e difração de raios X de pó. As técnicas analíticas confirmaram a obtenção de MOF-199. A temperatura nas sínteses com cloreto de Cu2+ foi a única variável significativa nos rendimentos de reação. As sínteses realizadas com acetato de Cu2+ proporcionaram rendimentos mais elevados em comparação ao cloreto de Cu2+, embora as condições de síntese não tenham sido significativas.
