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. …
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.
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…
A longitudinal investigation on problematic Facebook use, psychological distress and well-being during the second wave of COVID-19 pandemic
2022
AbstractThe social isolation and the subsequent, increased use of Social Networking Sites due to the COVID-19 pandemic have had an impact on subjective well-being around the world. The present longitudinal study examined whether changes in psychological distress and well-being during the Italian second wave of the pandemic differ among people with different levels of Problematic Facebook Use (PFU). A total of 493 participants (Mage = 24.55 ± 7.25; 80.3% females) completed measures of passive use of Facebook, social comparison orientation on Facebook, fear of missing out, psychological distress (depressive symptoms and fear of COVID-19 pandemic) and well-being across three waves. Latent clas…
Personality Variables as Predictors of Facebook Usage
2014
This study investigates the role of personality factors as predictors of Facebook usage. Data concerning Facebook usage and personality factors from 654 Facebook users were gathered using a web survey. Using path analysis, the results showed Openness was a predictor of Facebook early adoption, Conscientiousness with sparing use, Extraversion with long sessions and abundant friendships, and Neuroticism with high frequency of sessions. The possible role of Agreeableness in predicting low session frequency and friendships needs further validation.
Unemployment, Personality Traits, and the Use of Facebook
2021
Different personality traits respond differently to unfavourable life situations. Unemployment can have several negative social, economic, and domestic consequences. Many people use social media for a variety of reasons. The aim of this study is to examine the way different personality traits respond to Facebook in the period of unemployment. Data was obtained from 3,002 unemployed respondents in Nigeria. The study used regression model to analyse the data. Among the five personality traits, results indicated that the relationship between neuroticism and online social support was negative. However, the relationship between online social support and satisfaction was positive. The study highl…
Italian Amateur Pop-Rock Musicians on Facebook: Mixed Methods and New Findings in Music Making Research
2017
This chapter investigates how and why amateur musicians use social networking sites, employing a mixed-methods approach. Attention is focused on four big Italian Facebook communities of pop-rock musicians: drums, bass, guitar, and keyboard players (overall, 2,101 active users), analyzing the relational and textual data extracted from the web. The chapter analyzes the network structures emerging from the interactions among the users. It also identifies and maps the main areas of discussion (sound shaping, studio recording, marketplace, musical references, computer production, and relations) and the latent semantic dimension characterizing Facebook users’ activities, through social network an…
Hop: Histogram of patterns for human action representation
2017
This paper presents a novel method for representing actions in terms of multinomial distributions of frequent sequential patterns of different length. Frequent sequential patterns are series of data descriptors that occur many times in the data. This paper proposes to learn a codebook of frequent sequential patterns by means of an apriori-like algorithm, and to represent an action with a Bag-of-Frequent-Sequential-Patterns approach. Preliminary experiments of the proposed method have been conducted for action classification on skeletal data. The method achieves state-of-the-art accuracy value in cross-subject validation.
Face tracking and recognition: from algorithm to implementation
2002
This paper describes a system capable of realizing a face detection and tracking in video sequences. In developing this system, we have used a RBF neural network to locate and categorize faces of different dimensions. The face tracker can be applied to a video communication system which allows the users to move freely in front of the camera while communicating. The system works at several stages. At first, we extract useful parameters by a low-pass filtering to compress data and we compose our codebook vectors. Then, the RBF neural network realizes a face detection and tracking on a specific board.
Baltijas pētnieciskās žurnālistikas centra Re:Baltica darbība sociālajos tīklos: žurnālistu un auditorijas attieksmes
2021
Bakalaura darbā analizētas pētnieciskās žurnālistikas centra Re:Baltica aktivitātes sociālajos tīklos, to efektivitāte un lietotāju attieksme pret tām. Izmantojot Sociālās atbildības teorijas pieeju, noskaidroti pētnieciskās žurnālistikas uzdevumi, savukārt definējot sociālo tīklu, viltus ziņu un dezinformācijas jēdzienus, nozīmi un problēmas, kā arī noskaidrojot Facebook lomu masu komunikācijā, konstatēti sociālo tīklu izmantošanas iemesli un to efektivitāte auditorijas sasniegšanā pētnieciskajā žurnālistikā. Ar kontentanalīzes palīdzību konstatētas galvenās publikāciju tēmas un lietotāju reakcijas uz tām, savukārt, intervējot Re:Baltica žurnālistes, atklāti iemesli aktivitātēm sociālajos …
