In Situ Detection of Phosphorylated Platelet-derived Growth Factor Receptor β Using a Generalized Proximity Ligation Method
2007
Improved methods are needed for in situ characterization of post-translational modifications in cell lines and tissues. For example, it is desirable to monitor the phosphorylation status of individual receptor tyrosine kinases in samples from human tumors treated with inhibitors to evaluate therapeutic responses. Unfortunately the leading methods for observing the dynamics of tissue post-translational modifications in situ, immunohistochemistry and immunofluorescence, exhibit limited sensitivity and selectivity. Proximity ligation assay is a novel method that offers improved selectivity through the requirement of dual recognition and increased sensitivity by including DNA amplification as a…
The EU’s legislative framework and the issue of violence perpetrated against migrant women
2019
Following the traces of the introductory section of this book, the present chapter focus on the emerge intersection of the phenomena of violence and migration, through the chronological evolution of the European legal framework on the subject. As previously remarked, the western society in the last century brought up into the public attention a shared concern on the issue violence (Warr 1994), that has expanded through time (Gelles & Straus 1979). At an initial phase, the phenomenon has been mostly characterised by the gender aspect, there is, the association of violence to an asymmetric distribution of power between the genders (Bourdieu 1998). It is exactly on the asymmetric distribut…
Proximity Violence in Migration Times. A Focus in some Regions of Italy, France and Spain
2019
This volume, edited by Ignazia Bartholini, principal investigator of the PROVIDE - Proximity on Violence: Defence and Equity project (Rights, Equality and Citizenship Programme - 2014-2020) funded by the EU, shifted the interpretative focus of its research from gender-based to proximity violence. This theoretical intuition-assertion, fruitful too at empirical level, is informed by a wide-scale reconstruction of the phenomenon of migratory violence and corroborated by the results of the action research carried out by six international teams ˗ Ismu, Oxfam, Telefono Donna, Badia Grande, Aseis Lagarto, Samù International, the University of Jaén and the University of Palermo. Systems of protecti…
Riflessioni sul ruolo dell'assistente sociale nella presa in carico di migranti vittime di violenza di prossimità
2018
Le autrici affrontano il problema della violenza di prossimità subita dai rifugiati / richiedenti asilo durante il loro percorso migratorio. Inoltre, riflettono sul ruolo assunto dall'assistente sociale nel cosiddetto "processo di accompagnamento" verso un percorso di sensibilizzazione, emancipazione e responsabilizzazione personale delle vittime. The authors addresses the issue of proximity violence suffered by refugees/asylum seekers during their migration path. Furthermore, they reflects on the role assumed by the social worker on the so-called “accompaniment process” towards an awareness path, emancipation and personal empowerment of the victims.
Can Interactive Mediation Tools Bridge the Identity Gap Between the Public and the Art Museum?
2015
International audience; Consumer behaviour in the field of art museums appears to be influenced both by the identity of the public and the art museum and by the context. It is a matter not of changing museum content, but of bringing its identity closer to that of the public in order to promote access to art. The authors first present the theoretical and conceptual framework for their research and then suggest a qualitative methodological approach to addressing the issues described in the results.; La conducta del consumidor en los museos de arte parece estar influenciada tanto por la identidad del público y del museo como por el contexto. No se trata de cambiar el contenido del museo, pero …
phi-Best proximity point theorems and applications to variational inequality problems
2017
The main concern of this study is to introduce the notion of $$\varphi $$ -best proximity points and establish the existence and uniqueness of $$\varphi $$ -best proximity point for non-self mappings satisfying $$(F,\varphi )$$ -proximal and $$(F,\varphi )$$ -weak proximal contraction conditions in the context of complete metric spaces. Some examples are supplied to support the usability of our results. As applications of the obtained results, some new best proximity point results in partial metric spaces are presented. Furthermore, sufficient conditions to ensure the existence of a unique solution for a variational inequality problem are also discussed.
A New Extension of Darbo's Fixed Point Theorem Using Relatively Meir-Keeler Condensing Operators
2018
We consider relatively Meir–Keeler condensing operators to study the existence of best proximity points (pairs) by using the notion of measure of noncompactness, and extend a result of Aghajani et al. [‘Fixed point theorems for Meir–Keeler condensing operators via measure of noncompactness’, Acta Math. Sci. Ser. B35 (2015), 552–566]. As an application of our main result, we investigate the existence of an optimal solution for a system of integrodifferential equations.
Best proximity points for cyclic Meir–Keeler contractions
2008
Abstract We introduce a notion of cyclic Meir–Keeler contractions and prove a theorem which assures the existence and uniqueness of a best proximity point for cyclic Meir–Keeler contractions. This theorem is a generalization of a recent result due to Eldred and Veeramani.
Best proximity point results for modified α-proximal C-contraction mappings
2014
First we introduce new concepts of contraction mappings, then we establish certain best proximity point theorems for such kind of mappings in metric spaces. Finally, as consequences of these results, we deduce best proximity point theorems in metric spaces endowed with a graph and in partially ordered metric spaces. Moreover, we present an example and some fixed point results to illustrate the usability of the obtained theorems. MSC:46N40, 46T99, 47H10, 54H25.
Cyclic (noncyclic) phi-condensing operator and its application to a system of differential equations
2019
We establish a best proximity pair theorem for noncyclic φ-condensing operators in strictly convex Banach spaces by using a measure of noncompactness. We also obtain a counterpart result for cyclic φ-condensing operators in Banach spaces to guarantee the existence of best proximity points, and so, an extension of Darbo’s fixed point theorem will be concluded. As an application of our results, we study the existence of a global optimal solution for a system of ordinary differential equations.
