Academic promotion and leadership: 'moving the needle' for the enhancement of gender equality in Tunisian higher education institutional members of the RMEI network following the TARGET framework.

Although job opportunities, recruitment criteria, health insurance and social welfare are equally available regardless of sex, academic promotion at higher education institutions (HEIs) has so far been a challenging issue for women more than men. Even though there are not legislative policies or political strategies proscribing gender discrimination, the under-representation of women in high profile positions is thought-provoking as it was found by this study on collecting segregating data at the Faculty of Arts and Human Sciences of Sousse (FAHSS) and to a lesser degree at the National Engineering School of Sousse (ENISO). Given insufficient research in the area under investigation, and despite the shortage of data needed for examination, this study makes use of and analyses the available data collected from Sousse University. Built upon the findings, this paper sets forth to examine impediments as challenges to progress which are encountered by women. Despite the belief that gender parity has been acquired, it is still a challenge to progress to endorse the culture of gender equality at higher education institutions. The study entails the activities of the gender equality committee created at Sousse University in 2018 with the support of the Mediterranean Network of Engineering Schools (RMEI) and under the framework of the EU TARGET project entitled 'Taking a reflexive approach to gender equality at Institutional transformation'.

Assessment of intervertebral disc degeneration-related properties using finite element models based on [Formula: see text]-weighted MRI data.

Quantitative magnetic resonance imaging (MRI) provides useful information about intervertebral disc (IVD) biomechanical properties, especially those in relation to the fluid phase. These properties may improve IVD finite element (FE) models using data closer to physiological reality. The aim of this study is to investigate IVD degeneration-related properties using a coupling between MRI and FE modeling. To this end, proton density ([Formula: see text])-weighted MRI sequences of a porcine lumbar IVD were carried out to develop two biphasic swelling models with hyperelastic extracellular matrix behavior. The first model is isotropic, and the second one is anisotropic and takes into account the role of collagen fibers in the mechanical behavior of the IVD. MRI sequences permitted to determine the geometry and the real porosity mapping within the disc. The differentiation between disc components (nucleus pulposus, annulus fibrosus and cartilaginous end plates) was taken into account using spatial continuous distributions of the mechanical properties. The validation of the FE models was performed through two steps: the identification of the model's mechanical properties using relaxation compressive test and the comparison between the MRI after load porosity distributions and those numerically obtained using the set of identified properties. The results confirmed that the two developed FE models were able to predict the mechanical response of uniaxial time-dependent compressive test and the redistribution of porosity after load. A slight difference between the measured and the numerical local bulges of the disc was found. This study suggests that from the coupling between MRI imaging in different state of load and finite element modeling we can deduce relevant information that can be used in the assessment of the early intervertebral disc degeneration changes.
