Development of a green fluorescent tagged strain of Aspergillus carbonarius to monitor fungal colonization in grapes.
2011
An enhanced green fluorescent protein has been used to tag an OTA-producing strain of Aspergillus carbonarius (W04-40) isolated from naturally infected grape berries. Transformation of the fungus was mediated by Agrobacterium tumefaciens. The most efficient transformation occurred when the co-cultivation was done with 104 conidia due to higher frequency of resistance colonies (894 per 104 conidia) and lower background obtained. To confirm the presence of the hph gene in hygromycin resistant colonies, 20 putative transformants were screened by PCR analysis. The hph gene was identified in all the transformants. Variation on the expression levels of the eGFP was detected among the transformant…
Top Management Team Diversity and Ambidexterity: The Contingent Role of Shared Responsibility and CEO Cognitive Trust
2017
Earlier research has suggested that diversity is a double-edged sword when achieving organizational ambidexterity. While it may contribute to the development of new combinations of exploration and exploitation, it may also lead to disagreements and potential conflict within top management teams (TMTs). To improve our understanding of the effectiveness of diversity in ambidextrous organizations, we develop a synergistic perspective on TMT diversity and examine how two types of diversity – functional and age diversity – affect the achievement of organizational ambidexterity. We also identify shared responsibility and CEO cognitive trust as important contingencies that may complement the effec…
The degradation of intracrystalline mollusc shell proteins: a proteomics study of Spondylus gaederopus.
2021
Mollusc shells represent excellent systems for the preservation and retrieval of genuine biomolecules from archaeological or palaeontological samples. As a consequence, the post-mortem breakdown of intracrystalline mollusc shell proteins has been extensively investigated, particularly with regard to its potential use as a "molecular clock" for geochronological applications. But despite seventy years of ancient protein research, the fundamental aspects of diagenesis-induced changes to protein structures and sequences remain elusive. In this study we investigate the degradation of intracrystalline proteins by performing artificial degradation experiments on the shell of the thorny oyster, Spo…

El cambio estratégico y sus dimensiones: implicaciones sobre la composición y estructura de los equipos directivos
2017
El objetivo de esta tesis doctoral es analizar las implicaciones del cambio estratégico sobre el equipo directivo. Este estudio extiende la investigación sobre equipos directivos (TMT) basada en la Upper Echelons Theory planteando un modelo recursivo y dinámico de la relación características del TMT y cambio estratégico. En concreto analizaremos como las distintas dimensiones del cambio estratégico –alcance, intensidad y dirección– afectan a la composición y estructura del TMT, y específicamente, sus implicaciones sobre el tamaño, heterogeneidad (antigüedad, background educativo y funcional), rotación y estructura de poder en el TMT (concentración contra dispersión).
Relationship between cognitive performance and mobility over the life course
2018
We studied cross-sectional, longitudinal and temporal associations between executive function and life-space mobility in old age. We assessed the association between intellectual ability in early adulthood and physical functioning in old age, and the association between early life motor development and cognitive performance in early old age. The participants of the first dataset were 157 persons aged 76-91 y who were followed up for two years as part of the Life-Space Mobility in Old Age study, and who took part in measurements on executive function (EF) implemented with the Trail Making Test and Life-Space Assessment. The second dataset comprised persons from the Helsinki Birth Cohort Stud…
Strategic responses of medium sized firms: The role of TMT’s perceptions and characteristics in decision making processes
2017
Many decisions made by the organization’s top management team (hereafter called indifferently TMT or top management team) have a high likelihood of failure (Nutt, 1999). This situation might be shocking but indeed, it is much more common than one might think (Bloom et al., 2012). In fact, we can easily realize this reality when reading the current business press where we will probably be confronted with several cases of failures that have been caused by any type of TMT decisions. Of course, we will also see cases of success, exemplifying managers and recipes of good practices (e.g., Eide et al., 2016; Schrage, 2013); but these will be minor. Thus, as Bloom et al. (2012) state, the group of …
