Cultural Contagion from Micro to Macro: A Semiopragmatics Approach

2017

International audience; Although cultures are a group-based process, cultural change occurs on the level of the individual, through micro-level interactions which give rise to new representations. Based on the semiopragmatics approach to communications, this contribution will theorize this process of cultural evolution, linked to the phenomenon of contagion, notably assisted by media and internet-based communication, based on examples of recent emerging cultural trends.

La viralité dans l’espace public numérique

2018

Depuis 2007 et la campagne électorale de Ségolène Royal, « Désir d’avenir », les communicants, les militants et les activistes utilisent la potentialité des dispositifs sociotechniques au service de leur candidat et de la propagation de leurs idées. Les réseaux sociaux ont profondément changé la stratégie de communication des équipes de campagne qui ont préempté l’espace numérique en multipliant leur présence social (Facebook, Twitter, Instagram, etc.). Souvent composées de digital natives et d’individus maitrisant les codes et les rites en vigueur sur ces dispositifs, les équipes intègrent la force du canal de communication afin de renouveler la relation et la communication entre le politi…

Error messages in relational database management systems: A comparison of effectiveness, usefulness, and user confidence

2021

Abstract The database and the database management system (DBMS) are two of the main components of any information system. Structured Query Language (SQL) is the most popular query language for retrieving data from the database, as well as for many other data management tasks. During system development and maintenance, software developers use a considerable amount of time to interpret compiler error messages. The quality of these error messages has been demonstrated to affect software development effectiveness, and correctly formulating queries and fixing them when needed is an important task for many software developers. In this study, we set out to investigate how participants ( N = 152 ) …

Applying Axial Symmetries to Historical Silk Fabrics: SILKNOW’s Virtual Loom

2020

Symmetry is part of textile art in patterns and motifs that decorate fabrics, which are made by the interlacement of warp and wefts. Moreover, the 3D representation of fabrics have already been studied by some authors

Damping Provision by Different Virtual Synchronous Machine Schemes

2020

The adoption of virtual synchronous machine (VSM) schemes for the control of power converters is gaining more and more attention both in academia and industry. The VSM control strategies fall into the category of grid-forming converter controls, and they are intended for a range of different applications, providing specific services and different kinds of support to the grid. The paper investigates the possibility of damping provision to the system by VSM power converters. Different schemes are considered and compared, showing the opportunity of the investigated solutions through combined modal and time domain analyses. A specific modification of the power synchronization loop is recognized…

Vaginal infection of mice with HSV type 2 variant ER−: A new animal model for human primary genital HSV type 2 infections

1992

Abstract Studying the pathogenesis of vaginal infections in mice with two variants of Herpes simplex virus type 2 (HSV-2) strain ER we observed that both variants ER+ and ER− caused severe vaginitis but only ER+ invaded the CNS leading to lethal neurological disease. In contrast, mice infected with ER− cleared the virus from the vagina and recovered from infection. ER+ and ER− expressed equal levels of thymidine kinase (TK) indicating a TK-independent difference in neurovirulence. Using the non-neurovirulent variant ER−, we were able to investigate humoral immune responses late after infection. Vaginal infection with ER− suppressed serum antibody formation after a secondary systemic HSV-1 i…

Transfection of lipoma cells with papilloma bovine virus subgenomic fragment.

1991

Abstract Lipoma cells with consistent chromosomal aberration have been transfected with plasmids carrying papilloma bovine virus subgenomic fragment (PBV 69). The succesful transformation of the cells was ascerted on the changed growth pattern of the cells in liquid medium, colony formation in soft agar and modified cell appearrance in electron microscopy; transfection with PBV 69 has not been, however, sufficient to immortalize lipoma cells.

SV40 transformed fibroblasts recognize the same 140 kD fibronectin chemotactic fragment as non-transformed cells

1985

SV40-virus-transformed human embryonal fibroblasts show an enhanced chemotactic response to the glycoprotein fibronectin. However, they recognize the same chemotactic active region as non-transformed fibroblasts. The result suggests that an enhancement of chemotaxis by fibroblasts which have been transformed with Simian Virus 40 is due not to the utilization of further chemotactic domains in the molecule, but to an increased sensitivity of the cells to the chemoattractant.

Building a political image on Instagram: A study of the personal profile of Santiago Abascal (Vox) in 2018

2020

Due to Instagram’s growing popularity in Spain, politicians have also begun to turn to this social network increasingly more. Accordingly, this paper analyses the visual and textual discourse of 259 posts published throughout 2018 on the personal Instagram profile of Santiago Abascal, the leader of the party Vox. Insofar as he is the Spanish politician with the highest number of followers on Instagram, the aim here is to analyse how he uses this social network in order to identify possible strategies that justify his growing number of followers. In the analysis, special attention was paid to aspects that might have contributed to the (self)presentation of Abascal and the promotion of his pa…
