Social network site communities as agents and spaces of pursuing influence in society : forms, stages and attributes of building communicative power

2018

Before the emergence and high popularity of social media, individuals or even collectives of individual citizens rarely had strong voice in public discourse. Social media, and its social network sites (SNS), have allowed individual people to form communities to create discourse around issues they find meaningful, and even unite their power to fight for a common cause and potentially influence changes in society. The objectives of the thesis were to investigate what types of ‘societal influence (SI) oriented SNS communities’ the Internet and social media arena consists of and how their potential communicative power is formed, even to the extent that they can challenge news media and business…

The social significance of the Facebook Like button

2015

In this paper we study social aspects of using the Like button for purposes of impression management, identity construction, and maintenance of social ties online. On the theoretical level our investigation combines Goffman’s notion of face-work with concepts of social network analysis, shedding light on what we dub ‘nano-level’ interaction and sociality on social networking sites. Our data come from a 2013 classroom survey in which 26 Finnish university students were asked about their motives for and ways of using the Like button. Our results show that though the Like button was designed to allow users to express their positive evaluations of the contents of Facebook posts, comments, and p…

Lietotāja digitālā vizuālā identitāte un tās vērtējums sociālajā tīklošanās vietnē “Instagram” (vecuma grupā no 18-35 gadiem)

2022

Bakalaura darba tēma “Lietotāja digitālā vizuālā identitāte un tās vērtējums sociālajā tīklošanās vietnē “Instagram” (vecuma grupā no 18-35 gadiem)”. Darba teorētiskā daļa balstās uz digitālās vizuālās identitātes veidojošajiem faktoriem, kā arī dažādiem vizuālās kultūras aspektiem un tās nozīmi mūsdienās. Ar vizuālās kontentanalīzes palīdzību tika analizēti sociālo tīklošanās vietņu patērētāju, “Instagram” lietošanas un vizuālo materiālu publicēšanas paradumi. Un ar interneta aptauju tika ievākti vispārīgi dati par digitālās vizuālās identitātes nozīmi patērētāju vidū. Bakalaura darba autore nonāca līdz secinājumam, ka digitālā vizuālā identitāte daļai “Instagram” patērētāju ir nozīmīga, t…

Interspecific information on predation risk affects nest site choice in a passerine bird

2018

Abstract Background Breeding site choice constitutes an important part of the species niche. Nest predation affects breeding site choice, and has been suggested to drive niche segregation and local coexistence of species. Interspecific social information use may, in turn, result in copying or rejection of heterospecific niche characteristics and thus affect realized niche overlap between species. We tested experimentally whether a migratory bird, the pied flycatcher Ficedula hypoleuca, collects information about nest predation risk from indirect cues of predators visiting nests of heterospecific birds. Furthermore, we investigated whether the migratory birds can associate such information w…

Compared Binding Properties between Resveratrol and Other Polyphenols to Plasmatic Albumin: Consequences for the Health Protecting Effect of Dietary …

2014

International audience; Phytophenols are considered to have beneficial effects towards human physiology. They are food microcomponents with potent chemopreventive properties towards the most three frequent contemporary human diseases, e.g., cardiovascular alterations, cancer and neurodegenerative pathologies. Related to this, the plasmatic form and plasmatic level of plant polyphenols in the body circulation are crucial for their efficiency. Thus, determinations of the binding process of resveratrol and of common flavonoids produced by major edible plants, berries and fruits to plasma proteins are essential. The interactions between resveratrol and albumin, a major plasma protein, were comp…

Design, synthesis and structure-activity relationship of 2-(3',4',5'-trimethoxybenzoyl)-benzo[b]furan derivatives as a novel class of inhibitors of t…

2009

The biological importance of microtubules in mitosis and cell division makes them an interesting target for the development of anticancer agents. Small molecules such as benzo[b]furans are attractive as inhibitors of tubulin polymerization. Thus, a new class of inhibitors of tubulin polymerization based on the 2-(3′,4′,5′-trimethoxybenzoyl)-benzo[b]furan molecular skeleton, with electron-donating (Me, OMe or OH) or electron-withdrawing (F, Cl and Br) substituents on the benzene ring, was synthesized and evaluated for antiproliferative activity, inhibition of tubulin polymerization and cell cycle effects. Adding a methyl group at the C-3 position resulted in increased activity. The most prom…

il volto della morte: le maschere funerarie della sepoltura dei preti morti di Gangi

2014

riassunto — Le mummie moderne e il signifcato recondito della doppia sepoltura nelle culture mediterranee moderne sono da tempo ampiamente dibattuti. In questo lavoro si discute di una particolare “collezione” di corpi di ecclesiastici, mummifcati ed esposti in un comune montano madonita della Sicilia, Gangi. I corpi, principalmente risalenti al XIX secolo, mummifcati per colatura come nella tradizione del tempo e vestiti degli abiti talari, sono esposti nel piano sottostante della Chiesa Madre, in quella che nella tradizione è detta la “fossa dei parrini” (fossa dei preti). Le mummie, a differenza di altri siti siciliani e mediterranei, sono altresì corredate di sonetto commemorativo e di …

summary — The modern mummies and the inner meaning of the double burial in Mediterranean cultures have long been debated. In this paper we discuss a particular “collection” of ecclesiastical bodies mummifed and displayed in a small mountain town of Sicily Gangi in the Madonie Mountains. The bodies dating back to the nineteenth century mummifed by pouring in the tradition of the time and carefully dressed in robes are exposed in the lower foor of the Chiesa Madre in what the tradition is called “fossa dei parrini” (pit of priests). The mummies unlike other Sicilian and Mediterranean sites are accompanied by commemorative sonnet and death mask made of fnish wax. The primary interest of our study was aimed specifcally at this particular manifestation of the double burial complex which lies in the representation of the face. The work expresses an examination of the concept of death mask in antiquity and leads to the conclusion that the place for its scenic values ritualization should be designed to the ostentation and the consolidation of the image of the Church and of the his power within the small rural society.Settore BIO/08 - Antropologia

The commitment of the GISIO-SItI to contrast Healthcare- Associated Infections and the experience of the prevalence studies in Sicily

2018

Surveillance of Healthcare-Associated Infections (HAIs) is essential to improve the quality of health services. The aim of this paper is to report the commitment of the Italian Study Group of Hospital Hygiene (GISIO) of the Italian Society of Hygiene, Preventive Medicine and Public Health (SItI) describing some experiences to contrast HAIs and antimicrobial resistance. Particularly, the commitment to contrast HAIs in intensive care with the SPIN-UTI project - Italian Nosocomial Infections Surveillance in ICUs, and in surgery with the ISCHIA project - Infections of Surgical Site in Arthroplasty Interventions - were described. Furthermore, some activities conducted in Sicily using repeated pr…

Synthesis and Structure-Affinity Relationships of Spirocyclic Benzopyrans with Exocyclic Amino Moiety

2019

σ1 and/or σ2 receptors play a crucial role in pathological conditions such as pain, neurodegenerative disorders, and cancer. A set of spirocyclic cyclohexanes with diverse O-heterocycles and amino moieties (general structure III) was prepared and pharmacologically evaluated. In structure-activity relationships studies, the σ1 receptor affinity and σ1:σ2 selectivity were correlated with the stereochemistry, the kind and substitution pattern of the O-heterocycle, and the substituents at the exocyclic amino moiety. cis-configured 2-benzopyran cis-11b bearing a methoxy group and a tertiary cyclohexylmethylamino moiety showed the highest σ1 affinity ( Ki = 1.9 nM) of this series of compounds. In…
