Analyse du caractère dynamique des recommandations dans l'industrie cinématographique : le cas des franchises de films

2016

The release of motion picture sequels by studios led to the emergence of interaction effects between sequels over the time and in consequence altering models predicting the box office. If some scholars have examined these interaction effects, they were limited to the box office revenues. The paper proposes an extension of the interaction effects to third-party recommendations. The results – covering 123 sequels – demonstrate the dynamic and persistent nature of the recommendations.

Gas-liquid-solid operation of a Long Draft Tube Self-ingesting Reactor (LDTSR)

2008

Gas-liquid stirred vessels are widely employed to carry out chemical reactions involving a gas reagent and a liquid phase. The usual way for introducing the gas stream into the liquid phase is through suitable distributors placed below the impeller. An interesting alternative is that of using “self ingesting” vessels where the headspace gas phase is injected and dispersed into the vessel through suitable surface vortices. In this work the performance of a Long Draft Tube Self-ingesting Reactor dealing with gas-liquid-solid systems, is investigated. Preliminary experimental results on the effectiveness of this contactor for particle suspension and gas-liquid mass transfer performance in pres…

The use of the Dark Web as a COVID-19 information source : A three-country study

2022

The Dark Web (i.e., the anonymous web or Darknet) contains potentially harmful COVID-19-related information and content such as conspiracy theories and forged certificates. The Dark Web may particularly attract individuals who are suspicious about the pandemic, but there is no research concerning the use of the Dark Web as a COVID-19 information source. In this study, we investigated the role of COVID-19 skepticism, online activities, and loneliness in the use of the Dark Web platforms as a COVID-19 information source. The data (N = 3000) were gathered in April 2021 from 18 to 75-year-old respondents from Finland (n = 1000), Sweden (n = 1000) and the United Kingdom (n = 1000). The responden…

It’s Beyond Our Group ZPD : A Sociocultural Approach to the Unsuccessful Self-treatment of Writer’s Block in Times of COVID-19

2020

This study is a replication of Upper (1974). Our results are identical. We too have been unable to focus and accomplish our writing goals since the beginning of the global pandemic. We are certainly not alone, and we would like to recognize all of our colleagues who have also had to take on additional responsibilities at work and at home over the past year that have made writing nearly impossible. nonPeerReviewed

Co-culture of rat brain cells as a tool for studying cell-cell interactions

2012

Brain capillary endothelial cells (BCECs) form the blood-brain barrier (BBB) in response to interaction with other brain cells (astrocytes, pericytes and neurons). BCECs are characterized by tight junctions (TJ), maturation and stabilization of which require different proteins, such as occludin. When co-cultured with astrocytes and neurons, BCECs were found to form a monolayer resembling the natural BBB: paracellular flux of dopamine and sucrose (i.e. compounds which are unable to cross the BBB in vivo) significantly decreased (1), while the transendothelial electrical resistance (TEER) increased. In these conditions, BCECs produced a larger amount of occludin and tended to localize it at t…
