Sociālo tīklu izmantošana uzņēmējdarbības veicināšanas nolūkos.
2016
Mūsdienās internets un sociālie tīkli ir neatņemama cilvēku ikdienas sastāvdaļa, līdz ar to autors vēlējās noskaidrot, kā uzņēmumi izmanto sociālos tīklus kā sevis pozicionēšanas rīku un kādi faktori veicina patērētāju piesaisti kādam konkrētam zīmolam. Maģistra darba mērķis ir izpētīt uzņēmuma mērķtiecīgu sevis pozicionēšanu sociālajos tīklos un noskaidrot, vai tas ir devis kādus ieguvumus uzņēmuma attīstībai. Pētījuma teorētiskajā daļā tiek apskatīta speciālā literatūra par sociālo tīklu mārketinga teorētiskajiem aspektiem, sociālajos tīklos atrodamo informāciju un to nozīmi priekš uzņēmumiem. Papildus tiek sniegts ieskats uzņēmumu pozicionēšanās stratēģijās un metodēs sociālajos tīklos. …
Affective matching of odors and facial expressions in infants: shifting patterns between 3 and 7 months.
2016
Recognition of emotional facial expressions is a crucial skill for adaptive behavior. Past research suggests that at 5 to 7 months of age, infants look longer to an unfamiliar dynamic angry/happy face which emotionally matches a vocal expression. This suggests that they can match stimulations of distinct modalities on their emotional content. In the present study, olfaction-vision matching abilities were assessed across different age groups (3, 5 and 7 months) using dynamic expressive faces (happy vs. disgusted) and distinct hedonic odor contexts (pleasant, unpleasant and control) in a visual-preference paradigm. At all ages the infants were biased toward the disgust faces. This visual bias…
The impact of visual working memory capacity on the filtering efficiency of emotional face distractors.
2018
Emotional faces can serve as distractors for visual working memory (VWM) tasks. An event-related potential called contralateral delay activity (CDA) can measure the filtering efficiency of face distractors. Previous studies have investigated the influence of VWM capacity on filtering efficiency of simple neutral distractors but not of face distractors. We measured the CDA indicative of emotional face filtering during a VWM task related to facial identity. VWM capacity was measured in a separate colour change detection task, and participants were divided to high- and low-capacity groups. The high-capacity group was able to filter out distractors similarly irrespective of its facial emotion. …
Sulle tracce di Proteo (Odissea 4, 382 ss). Tra memoria tecnica e psicologia della memoria
2023
In Odyssey, Book 4, Proteus, the old man of the sea, is represented as a divine figure in possess of peculiar skills: a prophetic art as well as a metamorphic one, which, full of tricks (dolìe techne), enables him to escape anyone who tries to capture him for knowing his/her own future, and this is properly the case of the Spartan king Menelaus. In this way, it emerges that the Proteus’ expertise, a technical one, depends on the methodic recalling to the memory of various morphological status, whose repeated seriality is the guarantee of being successful in changing his form continuously: the use of the expression “he (i.e. the old man) did not forget his tricky art” (v. 455) deserves consi…
A study of (im)politeness on the Facebook pages of the main Spanish political parties: the gender variable and face acts
2019
Este estudio pretende conocer qué sexo tiene mayor participación en las páginas de Facebook de los 5 principales partidos políticos españoles: Partido Socialista Obrero Español (PSOE), Partido Popular (PP), Ciudadanos, Unidos Podemos y Vox y si el comportamiento en función del sexo difiere en torno a los actos de refuerzo de la imagen (FFA - face flattering acts) y a los actos de ataque a la imagen (FTA - face threatening acts). Para ello, se ha elaborado un análisis métrico de la campaña electoral de las elecciones generales del año 2019 y se ha recogido un corpus de 2500 comentarios durante el último día, el 26 de abril.
Mechanisms of reciprocity and diversity in social networks: a modeling and comparative approach
2018
Individual-based computer models show that different mechanisms, proximity-based or emotional bookkeeping, can lead to reciprocation. By comparing social networks from different computer models with those of empirical data, we show that the models’ social networks bear limited resemblance with some features of the observed social networks. This indicates that additional social processes (third-party awareness) may be needed in these models to represent more accurately the social behavior and interaction patterns observed in group-living animals.
Facebook groups as citizen science tools for plant species monitoring
2021
I social network sono canali di comunicazione utilizzati per condividere enormi quantità di dati, che possono essere utilizzati per la ricerca scientifica, anche nel campo della biodiversità. Per sapere quanto i dati ricavati dai social network possono integrare quelli raccolti per scopi scientifici, è necessario individuarne i bias. Utilizzando i dati estratti da un gruppo Facebook specializzato nella flora vascolare siciliana, abbiamo analizzato quali sono i caratteri che aumentano la probabilità che una pianta spontanea venga fotografata e postata su un social network. A tal fine, abbiamo confrontato frequenze e attributi delle specie fotografate dai membri del gruppo Facebook con quelli…
Bridging Ecology and Evolution
2017
Already by the early dawn of evolutionary biology, it was appreciated that ecological differences among species’ habitats, resources, and environments were key drivers of evolution and speciation. Thus, research on interactions between ecology and evolution is not a novel endeavor. It has, however, become increasingly popular to provide these interactions with ‘a new wrapping’, that is, the study of eco-evolutionary dynamics [1]. Consequently, eco-evolutionary dynamics is not a newly developed theory but rather a novel framework within which to study the interplay of ecology and evolution.
Glomus ibericum, Septoglomus mediterraneum, and Funneliformis pilosus, three new species of arbuscular mycorrhizal fungi
2020
Three new arbuscular mycorrhizal fungal species—Glomus ibericum, Septoglomus mediterraneum, and Funneliformis pilosus—are described and illustrated. In the field, the three species were associated with roots of Ammophila arenaria (Poaceae), Elymus farctus (Poaceae), Otanthus maritimus (Asteraceae), and Echinophora spinosa (Apiaceae) colonizing maritime dunes located along the Mediterranean coast in eastern Spain. The novelty of these species is supported by morphological, molecular, and phylogenetic analyses. Single-species cultures of S. mediterraneum and F. pilosus were obtained using Trifolium repens as a host plant, both forming arbuscular mycorrhizae, whereas single-species cultures fr…
