Most cytokine receptors lack intrinsic kinase activity and many of them signal via Janus kinases (Jaks). These tyrosine kinases are associated with cytokine receptor subunits, they become activated upon receptor triggering and subsequently activate downstream signalling events, e.g. the phosphorylation of STAT transcription factors. The successful interplay between cytokines, their receptors and the connected Jaks not only determines signalling competence but is also vital for intracellular traffic, stability, and fate of the cognate receptors. Here, we will discuss underlying mechanisms as well as some structural features with a focus on Jak1 and two of the signal transducing receptor subunits of interleukin (IL)-6 type cytokines, gp130 and OSMR. Regions that are critically involved in Jak-binding have been identified for many cytokine receptor subunits. In most cases the membrane-proximal parts comprising the box1 and box2 regions within the receptor are involved in this association while, within Jaks, the N-terminal FERM domain, possibly together with the SH2-like domain, are pivotal for binding to the relevant receptors. The exclusive membrane localisation of Jaks depends on their ability to associate with cytokine receptors. For gp130 and Jak1, it was shown that the cytokine receptor/Jak complex can be regarded as a receptor tyrosine kinase since both molecules have the same diffusion dynamics and are virtually undissociable. Furthermore, Jaks take an active role in the regulation of the surface expression of at least some cytokine receptors, including the OSMR and this may provide a quality control mechanism ensuring that only signalling-competent receptors (i.e. those with an associated Jak) would be enriched at the cell surface.

In this paper we would like to thoroughly cover the problem of computing all kernels, i.e. minimal outranking and/or outranked independent choices in a bipolar- valued outranking digraph. First we introduce in detail the concept of bipolar-valued characterisation of outranking digraphs, choices and kernels. In a second section we present and discuss several algorithms for enumerating the kernels in a crisp digraph. A third section will be concerned with extending these algorithms to bipolar-valued outranking digraphs. [less ▲]

Cette communication présente des résultats de recherche afférant à la reprise d’entreprise familiale par des filles d’entrepreneurs. Nous identifions les différentes stratégies mises en oeuvre par les femmes repreneuses dans ce contexte d’entreprise familiale pour asseoir leur crédibilité et affirmer leur identité de femmes chefs d’entreprise. Ces stratégies peuvent se concevoir en termes de choix des personnes-clés dans leur entourage, de développement de compétences spécifiques, de gestion des ressources humaines, ou de comportements en matière financière et bancaire.

While previous work has found cognitive ability to be strongly associated with whether older adults use the Internet, we consider whether cognitive ability also differentiates basic aspects of use. Four measures of use are considered: having high-speed access, length of time since initial household adoption, self-reported time using the Internet, and whether any of the respondent's Internet use involves the Web in addition to e-mail. In all cases, we find associations with cognitive ability, although effects are sometimes mediated to nonsignificance by subsequent attainments, especially education. Given how central social support is to discussions of older adults navigating the Internet, we look also at reports of the availability of such support, and we find that cognition is positively related to respondents having someone available to help them with Internet problems. Taken together, our results suggest strongly that the already cognitively advantaged are much better positioned to reap the potential benefits of online tools to help older adults navigate social benefits and make complicated decisions.
