How visual attention to social media cues impacts visit intention and liking expectation for restaurants

Purpose. This research examined how social media (TripAdvisor) content influences restaurant visit intentions and liking expectations, how online review valence affect the viewing behavior of the social media page, and which social media elements capture the initial attention of the consumer. Design/methodology/approach. The study used eye-tracking and self-reported data, and applied a 2-within-subjects design manipulating rating valence. Findings. The pictures posted by firms and opinions posted by users attracted consumers’ attention. However, in the negative valence condition, participants needed to expand upon the content by reading additional (and more detailed) online reviews with specific cues, revisited the content more often, and more closely fixated on specific online ratings. Moreover, the picture of the restaurant was the first area seen (reflecting a bottom-up process) and the third-party ad tended to be viewed last (reflecting selective attention). Implications. All social media elements are seen but only some affect decisions, with negatively (vs. positively) valenced reviews requiring consideration of an extra element. Of relevance to managers, this study stresses the importance of the pictorial element and the influence of user-generated content on the attention and judgment of consumers. Originality. This study suggests that, in order to form an opinion, viewers devote more cognitive effort and attention when evaluating restaurants with negatively (vs. positively) valenced reviews. However, viewing patterns appear unaffected by review valence. It also demonstrates how consumers pay attention to different social media elements

Highly conductive, ionic liquid-based polymer electrolytes

In this manuscript is reported a thermal and impedance spectroscopy investigation carried out on quaternary polymer electrolytes, to be addressed as separators for lithium solid polymer batteries, containing large amount of the N-methyl-N-propylpyrrolidinium bis(fluorosulfonyl)imide ionic liquid. The target is the development of Li+ conducting membranes with enhanced ion transport even below room temperature. Polyethylene oxide and polymethyl methacrylate were selected as the polymeric hosts. A fully dry, solvent-free procedure was followed for the preparation of the polymer electrolytes, which were seen to be self-consistent and handled even upon prolonged storage periods (more than 1 year). Appealing ionic conductivities were observed especially for the PEO electrolytes, i.e., 1.6 × 10-3and 1.5 × 10-4 S cm-1 were reached at 20 and -20°C, respectively, which are ones the best, if not the best ion conduction, never detected for polymer electrolytes

Localización cromosómica de cuatro genes de peroxidasa de Clase III en trigo

In previous work, deduced amino acid sequences from twenty wheat peroxidase genes were assigned to seven groups designated as TaPrx108 to TaPrx114. Some of these apoplastic peroxidases, have previously shown to play different roles in the plant defense responses to infection by the cereal cyst nematode Heterodera avenae. In the present study, PCR marker analysis using Sears’s aneuploid wheat lines cv. ‘Chinese Spring’, was used to locate four genes encoding peroxidase isozymes. The TaPrx111-A, TaPrx112-D and TaPrx113-F genes were located on the short arm of chromosome 2B and the TaPrx109-C on the long arm of chromosome 1B. These results would agree with the synteny between wheat and rice chromosomes previously established in other studies.En un estudio previo se caracterizaron, alinearon y relacionaron 20 genes que codifican para peroxidasas en trigo. Las proteínas resultantes se asignaron a siete grupos, denominados TaPrx108 a TaPrx114, de acuerdo a la similitud entre ellas y con peroxidasas de Clase III de otras especies. En líneas de trigo resistentes al nemátodo Heterodera avenae, se ha demostrado que algunas de estas peroxidasas apoplásticas están relacionadas con las respuestas de defensa frente a la infección por dicho nematodo. En el presente estudio se localizaron cromosómicamente cuatro genes que codifican para enzimas peroxidasas mediante la reacción de PCR, utilizando pares de cebadores específicos para cada gen y ADN aislado de lineas de trigo aneuploides del cultivar Chinese Spring. Los genes TaPrx111-A, TaPrx112-D y TaPrx113-F fueron asignados al brazo corto del cromosoma 2B, mientras que el gen TaPrx109-C se localizó en el brazo largo del cromosoma 1B. Estos resultados mantendrían la sintenia previamente establecida entre los cromosomas de trigo y arroz.Fil: Simonetti, Ester. Consejo Nacional de Investigaciones Científicas y Técnicas.

Three-way ordinal non symmetrical correspondence analysis for the evaluation of the patient satisfaction

In some recent articles, emphasis has been given to the partition of the Goodman-Kruskal’s tau index using orthogonal polynomials for the study of the non symmetrical relations in three-way contingency tables. New graphical techniques that consider such a partition and allow for the analysis of asymmetric relationships have been proposed, including three-way ordinal non symmetrical correspondence analysis (Simonetti, 2003). Such a procedure takes into account the presence of an ordinal predictor and response variables. In this paper we demonstrate the applicability of such a technique for the patient satisfaction evaluation

How online advertising competes with user-generated content in TripAdvisor. A neuroscientific approach.

The previous literature has almost ignored the interaction of user-generated content (UGC) and advertising content embedded in social media platforms. Visual attention is an important factor for tourist services in analyzing the value of online ads inserted close to UGC. Drawing on cognitive load theory, congruence research and dual processing models, the purpose of this study is to determine the effectiveness of online advertising on social media. A first study based on eye-tracking and EEG analysis was conducted to assess if there was a difference in visual attention and engagement when an ad was embedded in TripAdvisor content. Our findings showed that synergies between social media content and advertising content positively affect users’ visual attention. A second study, using an online survey, was carried out to assess the impact of congruent/incongruent ads on ad recall (2a) and, using eye-tracking, on visual attention (2b). Appropriate managerial implications are provided

Comparison of antioxidant compounds in pig meat from Italian autochthonous pig Suino Nero Lucano and a modern crossbred pig before and after cooking

This study aimed to evaluate and compare the antioxidant compounds of raw and cooked Longissimus lumbontm muscles from Suino Nero Lucano (SNL) and a modern crossbred (CG) pig. Vitamin E, phenols, histidine-containing peptides, and superoxide dismutase (SOD) activity have been detected in the raw and cooked meat of both genetic types. Cooking process decreased the content of all considered antioxidant compounds (P < 0.05). The antioxidant compounds of meat were significantly influenced by genetic type (P < 0.001). Autochthonous SNL raw and cooked meat showed a higher endogenous antioxidants content (P < 0.001) and SOD activity (P < 0.02) compared to CG meat. The results of this research highlighted that the pig meat, in particular autochthonous pig meat, showed good concentrations of endogenous antioxidant compounds that could confer functional properties to the product

Antifungal activity of phenolic and polyphenolic compounds from different matrices of Vitis vinifera L. against human pathogens

Phenolic compounds, the most widely distributed class of natural products in the plants, show several biological properties including antifungal activity. Phenolics contained in grapes can be classified in two main groups, flavonoids and non-flavonoids compounds. Variability and yield extraction of phenolic and polyphenolic compounds from different matrices of Vitis vinifera depends of cultivar, climate, soil condition and process technology. Unripe grapes, berry skins and seeds, leaves, canes and stems and not-fermented and fermented pomaces represent large reusable and valuable wastes from agricultural and agro-industrial processes. This review summarizes studies that examine the extraction method, chemical characterization, and antifungal activity of phenolic and polyphenolic compounds from edible and non-edible V. vinifera matrices against human fungal pathogens. In the world, around one billion people have fungal diseases related to skin, nail or hair and around 150 million have systemic diseases caused by fungi. Few studies on antifungal activity of plant extracts have been performed. This review provides useful information for the application of V. vinifera phenolics in the field of antifungals for human use

Cromosomal location of four genes encoding Class III peroxidases in wheat

Occupation and working outcomes during the Coronavirus Pandemic

Using data from the first wave of the SHARE COVID-19 Survey and additional information collected from the previous waves of SHARE (Survey of Health Ageing and Retirement in Europe), we explore the effects of job characteristics on two outcomes: (i) the probability of work interruptions and (ii) the length of such interruptions during the first phase of the Coronavirus Pandemic. In order to assess the relationship between job features and labour market outcomes, we define two indexes proxying the pre-COVID-19 technical remote work feasibility as well as the level of social interaction with other people while working. Moreover, we use an indicator that classifies ISCO-08 3-digit job titles based on the essential nature of the good or service provided. We find that job characteristics have been major determinants of the probability of undergoing work interruptions and their duration. In addition, we show that women have been negatively affected by the Pandemic to a much larger extent than men, suggesting the relevance of the intrinsic characteristics of jobs they are mainly involved in, and the role of gender selection into specific activities. Not only females were more likely to have undergone work interruptions but they also exhibited larger probabilities of longer work breaks. A similar impact is seen for self-employed and less-educated workers
