La città contemporanea e il territorio agricolo. Una relazione in continuo divenire
2014
Does the balanced relationship between the city and the country, typical of the birth of the urban centers and still existing in the eighteenth century, hold on until today? Can the relationship between the two parts be still considered an equal relationship? And again, can the “limits” of the contemporary city, with their residue of agricultural land be considered key points for the renaissance of a contemporary ecologically-oriented city? These are some questions underlying the research of which this paper presents the results. In order to answer these questions, this research has reflected on the transformation, over the centuries, of the relationship between town and country, on the mai…
Economía social y dinámica innovadora en los sistemas territoriales de producción y de innovación. Especial referencia a los sistemas agroalimentarios
2008
Las cooperativas desarrollan su actividad económica de acuerdo con unos principios que pueden alimentar el crecimiento de una trama de relaciones socio-económicas (capital relacional) y socio-políticas (capital social) propicias, a su vez, para generar la confianza que requiere la cooperación entre empresas y entre éstas y el sistema científico-tecnológico. Así se podría facilitar la creación de la proximidad organizada (relacional) necesaria para dotar de fluidez a las relaciones entre actores distintos dentro de los sistemas territoriales de producción y de innovación. Pero la presencia de una amplia red de cooperativas también podría definir ciertas inercias y factores de bloqueo. Este a…
Social Proximity and Environmental NGO Relationships in Corporate Sustainability Reports
2014
This study demonstrates how three Finnish companies constructed their stakeholder relationships with environmental NGOs (ENGOs) in terms of social proximity in their sustainability reports between 2003 and 2012. The study identifies five types of stakeholder relationship between ENGOs and corporations constructed in the reports: monetary, management system, collaborative, dialogue and conflicting. Within these relationships the level of constructed social proximity and level of trust vary. The results indicate that, within the 10 years we examined, a change has occurred in the ENGO relationships constructed in corporate sustainability reports: they have shifted from being non-stakeholder re…
Virtual proximity and transnational familyhood : a case study of the digital communication practices of Poles living in Finland
2020
The article presents a study of five Polish multicultural and multilingual families in Finland, and their engagement in digitally mediated family communication. Explored through an ethnographic inquiry into the in-app communication practices of Polish migrant mothers and children, the study contributes to the body of research at the intersection of new media and communication, transnational family and migration studies, and family multilingualism. Building on the concept of virtual proximity, which refers to the emotional closeness between individuals afforded by digital technologies and mobile communication, the study identifies four thematic patterns in participants’ practices in digital …
A note on best approximation in 0-complete partial metric spaces
2014
We study the existence and uniqueness of best proximity points in the setting of 0-complete partial metric spaces. We get our results by showing that the generalizations, which we have to consider, are obtained from the corresponding results in metric spaces. We introduce some new concepts and consider significant theorems to support this fact.
Best Proximity Point Results in Non-Archimedean Fuzzy Metric Spaces
2013
We consider the problem of finding a best proximity point which achieves the minimum distance between two nonempty sets in a non-Archimedean fuzzy metric space. First we prove the existence and uniqueness of the best proximity point by using di fferent contractive conditions, then we present some examples to support our best proximity point theorems.
The existence of best proximity points in metric spaces with the property UC
2009
Abstract Eldred and Veeramani in [A.A. Eldred, P. Veeramani, Existence and convergence of best proximity points, J. Math. Anal. Appl., 323 (2006), 1001–1006. MR2260159] proved a theorem which ensures the existence of a best proximity point of cyclic contractions in the framework of uniformly convex Banach spaces. In this paper we introduce a notion of the property UC and extend the Eldred and Veeramani theorem to metric spaces with the property UC.
Best proximity points: Convergence and existence theorems for p-cyclic mappings
2010
Abstract We introduce a new class of mappings, called p -cyclic φ -contractions, which contains the p -cyclic contraction mappings as a subclass. Then, convergence and existence results of best proximity points for p -cyclic φ -contraction mappings are obtained. Moreover, we prove results of the existence of best proximity points in a reflexive Banach space. These results are generalizations of the results of Al-Thagafi and Shahzad (2009) [8] .
Best proximity point theorems for rational proximal contractions
2013
Abstract We provide sufficient conditions which warrant the existence and uniqueness of the best proximity point for two new types of contractions in the setting of metric spaces. The presented results extend, generalize and improve some known results from best proximity point theory and fixed-point theory. We also give some examples to illustrate and validate our definitions and results. MSC:41A65, 46B20, 47H10.
The trade-enhancing effect of immigration networks: New evidence on the role of geographic proximity
2012
Abstract We use migration-trade data from Italian, Portuguese and Spanish provinces to examine the importance of geographic proximity in the effectiveness of ethnic networks on bilateral trade. Empirical findings from the gravity model show that the migration-trade link is clearly in-province: exports from a province to a country do not receive any stimuli from immigrants from this country living outside of the province, once we control for country–province time-invariant fixed effects.
