Social Determinants of Success: Social Media, Corporate Governance and Revenue
2019
This study examined how social media (Twitter and LinkedIn) relates to the operating revenue by investigating the effect of the use of social media by the board of directors. To tackle this question, we analyzed the mediating and moderating relationship of social media on the effect of board size in operating revenue (turnover). We studied the implications of the use of social media by the board members by using structural equation modeling (SEM). The data consisted of a random sample of 100 companies listed on the NASDAQ. The study makes two main contributions. First, it shows interesting differences in the use of social media for the operating revenue. Our results suggest that while Twitt…
The social mediators: limits and challenges of a system
2011
Following a study aimed at measuring the limits and challenges of the social mediation system, the authors put forward an examination in this article of the mutual expectations of the social mediator and its employer, the urban community. This sociological study is comprehensive: it uses the method of the individual interview and focus group. The analysis of the results is supported by contributions from Boltanski and Thévenot in order to compare the reference “worlds” of both types of actor. It is supplemented by the analysis of notions of “system” (Foucault) and “professionalisation” (Hainaux et al., Bartoli). The authors try to understand the extent to which the actors understand involve…
Propagowanie idei zrównoważonego rozwoju w serwisach społecznościowych
2017
Problemy ekologiczne przekraczają granice polityczne, a wdrażanie zasad zrównoważonego rozwoju napotyka na bariery i jest kontestowane przez niektóre grupy społeczne. Dalsza realizacja w pełnym zakresie tej idei wymaga zatem głębokich przemian w społeczeństwie,poprzedzonych szerokimi konsultacjami społecznymi. W związku z tym tworzy się przestrzeń do edukacyjnych i promocyjnych działań na jej rzecz. Serwisy społecznościowe posiadają wielką i jeszcze nie w pełni docenianą siłę oddziaływania społecznego. Stosowane tam metody przekazu treści i sposoby argumentowania nie mieszczą się w klasycznych ramach. W prezentowanym artykule skupiono się na specyfice wykorzystania serwisów społecznościowyc…
Network-based indices of individual and collective advising impacts in mathematics
2020
AbstractAdvising and mentoring Ph.D. students is an increasingly important aspect of the academic profession. We define and interpret a family of metrics (collectively referred to as “a-indices”) that can potentially be applied to “ranking academic advisors” using the academic genealogical records of scientists, with the emphasis on taking into account not only the number of students advised by an individual, but also subsequent academic advising records of those students. We also define and calculate the extensions of the proposed indices that account for student co-advising (referred to as “adjusted a-indices”). In addition, we extend some of the proposed metrics to ranking universities a…
Connecting others: Does a tertius iungens orientation shape the relationship between research networks and innovation?
2021
Research on social networks and innovation emphasizes that individuals spanning structural holes and crossing institutional boundaries have more opportunities for knowledge recombination and innovation involvement. However, transforming the potential knowledge and resources available through personal networks to attain innovation can be difficult for the focal individual. Using an ego-network approach, this study examines whether and to what extent an individual strategic orientation to cooperation (i.e. tertius iungens) contributes to strengthening the relation between two personal network properties (structural and institutional separation) and involvement in innovation. Our analysis is c…
Prediction of User-Brand Associations Based on Sentiment Analysis
2023
Finding the right users to be chosen as targets for advertising campaigns is not a trivial task, and it may allow important commercial advantages. A novel approach is presented here for the recommendation of new possible consumers to brands interested in distributing advertising campaigns, ranked according to the “compatibility” between users and brands. A database containing both descriptions associated with different brands, and textual information about users' opinions on different topics, is required in input. Then, sentiment analysis techniques are applied to measure to what extent the users match with the brands, based on the texts associated with their opinions. The approach has been…
ERIS: An Approach Based on Community Boundaries to Assess Polarization in Online Social Networks
2022
Detection and characterization of polarization are of major interest in Social Network Analysis, especially to identify conflictual topics that animate the interactions between users. As gatekeepers of their community, users in the boundaries significantly contribute to its polarization. We propose ERIS, a formal graph approach relying on community boundaries and users' interactions to compute two metrics: the community antagonism and the porosity of boundaries. These values assess the degree of opposition between communities and their aversion to external exposure, allowing an understanding of the overall polarization through the behaviors of the different communities. We also present an i…
Evaluation of the impact of training effort in workers employability within the institutional Spanish training model
2011
Resumen tomado de la publicación Título, resumen y palabras clave en español e inglés Disponible la versión en inglés Se analiza la asociación entre cantidad de formación y empleabilidad mediante una investigación no experimental con dos grupos no equivalentes. Se considera que la operativización de la cantidad de formación proporciona un indicador próximo al esfuerzo formativo realizado. Así, se estudió la variable independiente esfuerzo formativo (número de cursos) y la dependiente, empleabilidad (indicadores de ocupación, enriquecimiento de actividad y desempeño). Los resultados muestran que la formación está asociada al enriquecimiento de la actividad, sobretodo si los trabajadores pert…
Self-reported life-space mobility in the first year after ischemic stroke: longitudinal findings from the MOBITEC-Stroke project
2023
Abstract Background Life-space mobility is defined as the size of the area in which a person moves about within a specified period of time. Our study aimed to characterize life-space mobility, identify factors associated with its course, and detect typical trajectories in the first year after ischemic stroke. Methods MOBITEC-Stroke (ISRCTN85999967; 13/08/2020) was a cohort study with assessments performed 3, 6, 9 and 12 months after stroke onset. We applied linear mixed effects models (LMMs) with life-space mobility (Life-Space Assessment; LSA) as outcome and time point, sex, age, pre-stroke mobility limitation, stroke severity (National Institutes of Health Stroke Scale; NIHSS), modified R…
Quel concept de culture pour penser la socialisation des migrants ?
2016
International audience; La mondialisation économique et sociale rend toujours plus prégnante et visible la question des migrations entre sociétés. Qu’ils soient globetrotteurs professionnels, étudiants, migrants économiques, demandeurs d’asile ou clandestins, de nombreux individus cherchent à s’installer plus ou moins durablement au sein d’une société étrangère. De fortes pressions migratoires vers les pays de l’Union Européenne, vers l’Océanie ou le continent Nord-Américain font la Une des médias lorsque des tragédies humaines mettent en lumière la dimension humanitaire de ce phénomène géopolitique, économique et social. La progression chiffrée du nombre de migrants dans le monde est bien …
