Does IT Spending Matter on Hospital Financial Performance and Quality?

This research explored impacts of IT spending on hospital financial performance and hospital quality. We developed two research hypotheses accordingly. The first hypothesis was that IT spending would be positively related to the hospital financial performance, and the second hypothesis was that hospitals with higher IT spending would have better quality metrics. We used the 2017 American Hospital Association Survey data and the HCAHPS dataset from Medicare website. We tested three hospital financials and three quality measures. We employed T-Tests and ANOVA models to test the hypotheses. Results were inconclusive for both hypotheses. Evidence showed statistical significance on two out of seven tests

Psychanalyse et psychiatrie

La psychiatrie et la psychanalyse ont jadis cohabité dans une sorte de complémentarité. À l’ère des données probantes et de l’« evidence based medecine », la psychanalyse se voit maintenant accusée d’être incapable d’offrir des résultats validés scientifiquement. Ses avancées cliniques, sa métapsychologie sont devenues suspectes. Pourtant, compte tenu de la complexité de l’appareil psychique, il demeure vital d’utiliser une pluralité de modalités épistémologiques pour dynamiser les voies de recherche, tant sur le plan théorique que clinique. Comment, et à quelles conditions, poursuivre le dialogue toujours nécessaire entre psychiatrie et psychanalyse 

Reading Exercises

" The exhibition Reading Exercises juxtaposes recent works that, each in their own way, speak to a renewed relationship to reading, viewed as a space for productive experimentation and critical investigation. As the title suggests, reading is addressed and deployed in this exhibition specifically as an exercise–physical, mental, cognitive, pedagogical, epistemological, political, ethical, etc. Whether considered in the sense of training (requiring repetition and work, as in long-term effort), or associated with the social, cultural and political conditions of individual as well as collective practice, the expression “reading exercises” aims to convey the complexity of this activity that cannot be confined to the mere notion of a profound literary experience cut off from the outside world.

Permanent set and stress softening constitutive equation applied to rubber like materials and soft tissues

International audienceMany rubber like materials present a phenomenon known as Mullins effect. It is characterized by a difference of behavior between the first and second loadings and by a permanent set after a first loading. Moreover, this phenomenon induces anisotropy in an intially isotropic material. A new constitutive equation is proposed in this paper. It relies on the decomposition of the macromolecular network into two parts: chains related together and chains related to fillers. The first part is modeled by a simple hyperelastic constitutive equation whereas the second one is described by an evolution function introduced in the hyperelastic strain energy. It contributes to describe both the anisotropic stress softening and the permanent set. The model is finally extended to soft tissues mechanical behavior that present also stress softening but with an initially anisotropic behavior. The two models are successfully fitted and compared to experimental data
