    • Are family firms really more socially responsible? 

      Cruz, Cristina; Larraza Kintana, Martín Upna; Garcés Galdeano, Lucía Upna; Berrone, Pascual (SAGE, 2014)   Artículo / Artikulua  OpenAccess
      This paper conducts an empirical study as to whether family firms are more socially responsible than their non-family counterparts, and explores the conditions in which this difference in social behavior occurs. We argue ...
    • Depletion of the heaviest stable N isotope is associated with NH4+/NH3 toxicity in NH4+-fed plants 

      Ariz, Idoia Upna; Cruz, Cristina; Morán Juez, José Fernando Upna; González Moro, María B.; García Olaverri, Carmen Upna; González Murua, Carmen; Martins Loucao, María A.; Aparicio Tejo, Pedro María Upna (BioMed Central, 2011)   Artículo / Artikulua  OpenAccess
      Background: In plants, nitrate (NO3-) nutrition gives rise to a natural N isotopic signature (δ15N), which correlates with the δ15N of the N source. However, little is known about the relationship between the δ15N of the ...
    • Family firms in Iberoamerican countries 

      Larraza Kintana, Martín Upna; Cruz, Cristina; Belausteguigoitia Rius, Imanol (Emerald Group Publishing Limited, 2013)   Artículo / Artikulua  OpenAccess
      The purpose of this paper is to introduce the special issue on family firms in Iberoamerican countries. The special issue aims at enlarging our understanding of the uniqueness of family firms by providing new evidence from ...
    • Leaf δ15N as a physiological indicator of the responsiveness of N2-fixing alfalfa plants to elevated CO2, temperature and low water availability 

      Ariz, Idoia Upna; Cruz, Cristina; Neves, Tomé; Irigoyen, J. Juan; García Olaverri, Carmen Upna; Nogués, Salvador; Aparicio Tejo, Pedro María Upna; Aranjuelo Michelena, Iker (Frontiers Media, 2015)   Artículo / Artikulua  OpenAccess
      The natural 15N/14N isotope composition (δ15N) of a tissue is a consequence of its N source and N physiological mechanisms in response to the environment. It could potentially be used as a tracer of N metabolism in plants ...
    • Mechanisms of ammonium toxicity and the quest for tolerance 

      Esteban Terradillos, Raquel; Ariz, Idoia Upna; Cruz, Cristina; Morán Juez, José Fernando Upna (Elsevier, 2016)   Artículo / Artikulua  OpenAccess
      Ammonium sensitivity of plants is a worldwide problem, constraining crop production. Prolonged application of ammonium as the sole nitrogen source may result in physiological and morphological disorders that lead to decreased ...
