The relationship between human resources and information and communication technologies: Spanish firm-level evidence
Galve-Górriz,Carmen; Gargallo Castel,Ana;
Journal of theoretical and applied electronic commerce research , 2010, DOI: 10.4067/S0718-18762010000100003
Abstract: increased attention to the economic impact of information and communication technologies (ict) underscores the impact of ict on the social side of the ?digital divide.? ict and individual and organizational changes are often closely related. this paper examines the main characteristics of the relationship between ict and human resources in spanish firms, in the context of a developed country with an incidence-rate of ict slightly below the average of its area. the data on 1,269 spanish manufacturing firms has been taken from the survey of business strategies (sbs) of the fundación empresa pública (spanish foundation) of spain. our results suggest that ict are related to higher levels of qualification, higher levels of r&d workers, and higher levels of training per worker. moreover, firms that invest in ict offer higher levels of average wages. these results confirm the relationship between technological innovation, and organizational and human changes. managers and public administrators should take into account such mutual interrelations in order to optimize their decisions concerning investment in human and technological resources.
Family ownership and firm performance: The net effect of productive efficiency and growth constraints
Galve-Górriz,Carmen; Salas-Fumás,Vicente;
Innovar , 2011,
Abstract: this paper investigates differences in the behaviour and performance of listed spanish family and non-family firms resulting from the interaction of differences in productive efficiency and in preferences for control between the two groups of firms. we find that family firms grow at a smaller rate, choose less capital-intensive productive technologies and are more efficient in production than non-family firms are. the evidence is consistent with institutional theories of the firm that predict competition among governance forms for the transactions to be governed to minimize production and transaction costs. the results of the paper highlight the relevance of using measures of productive efficiency, instead of measures of profitability, to test the effect of ownership in the performance of firms.

EJERCICIO DE LAS FUNCIONES EMPRESARIALES POR PARTE DE LOS SOCIOS EN LAS COOPERATIVAS AGRARIAS / THE EXECUTION OF MANAGERIAL FUNCTIONS BY THE MEMBERS OF AGRARIAN COOPERATIVES
Idana SALAZAR TERREROS,Carmen GALVE GóRRIZ
Revista de Estudios Cooperativos , 2010,
Abstract: El objetivo de este trabajo es analizar cómo es efectuada por parte de los socios la coordinación de la empresa cooperativa agraria. Dicha coordinación ha sido analizada a través del análisis de las funciones que deben desarrollar los socios como empresarios. Estas funciones son enumeradas, descritas teóricamente y analizadas a partir de una muestra de cooperativas agrarias pertenecientes a la Denominación de Origen Calificada Rioja. Entre los principales resultados obtenidos cabe destacar que, en la mayoría de los casos analizados, la función de inversor es realizada sin que exista separación con la desempe ada como proveedor; el control formal es ejercido bajo el principio democrático de un hombre un voto; existe poca delegación de las actividades de gestión en una gerencia profesionalizada y cuando esta delegación se produce, no se obtiene niveles de eficiencia significativamente superiores; la organización de actividades muestra una clara especialización en las primeras fases del ciclo productivo y una alta concentración de ventas; por último, la selección de personal es realizada exigiendo unos niveles de cualificación adecuados en cada departamento. / The aim of this work is to analyse how the coordination of the agrarian cooperative firm is brought about by the members. Said coordination has been analysed by means of a study of the functions which members have to develop in their role as managers. These functions have been numbered; theoretically described, and analysed by using a sample of agrarian cooperatives belonging to the Domination of Origin Qualified Rioja. From the principal results obtained, we can highlight the fact that, in most cases analysed, formal control is exercised under the democratic principle, “one-man-one-vote”; where little delegation of management activities exists in professional management and when this delegation occurs, the cooperative does not obtain higher efficiency levels. The organisation of activities shows evident specialization in the first stages of the production cycle and a high sales concentration. Finally, the selection of personnel is made by the appropriate qualification levels required in each department.

Abstract: FUNDAMENTO: La importancia de la dieta como causa de diversas enfermedades y la posibilidad de intervención educativa en el periodo escolar, hacen recomendable conocer las actitudes de los jóvenes respecto a la nutrición y sus hábitos alimentarios. MéTODOS: Estudio transversal. Se realizó una encuesta autoadministrada sobre hábitos y conocimientos respecto a la nutrición, en una muestra aleatoriamente extraída de 543 escolares de 1o de Ense anza Secundaria Obligatoria (ESO) (13 a os) de la ciudad de Zaragoza, incluyendo una valoración del consumo de alimentos mediante recuerdo de 24 horas y cuestionario de frecuencia de consumo semanal. Se realizó una prueba piloto en 50 individuos, con validación mediante entrevista personal en 15 casos. RESULTADOS: Se analizaron 516 cuestionarios. Un 41,5% de la muestra reconoció que la publicidad influía en su alimentación. Se encontró una mayor implicación femenina en los temas relacionados con la alimentación. La encuesta de consumo reflejaba una dieta normocalórica, muy hiperproteica y baja en carbohidratos, con exceso de lípidos en varones. Se consumía en exceso carne y derivados y dulces y golosinas, mientras se apreció un consumo bajo de cereales, pescado y patatas. CONCLUSIONES: Es necesario realizar actividades educativas en la edad escolar respecto a la composición de los alimentos y dieta adecuada, ense ando a mantener una actitud crítica frente a la publicidad de alimentos. Debe recomendarse una disminución de la ingesta de carnes y dulces, y un incremento del consumo de hidratos de carbono complejos y pescado.
Array of planar Penning traps as a nuclear magnetic resonance molecule for quantum computation
G. Ciaramicoli,F. Galve,I. Marzoli,P. Tombesi
Physics , 2005, DOI: 10.1103/PhysRevA.72.042323
Abstract: An array of planar Penning traps, holding single electrons, can realize an artificial molecule suitable for NMR-like quantum information processing. The effective spin-spin coupling is accomplished by applying a magnetic field gradient, combined to the Coulomb interaction acting between the charged particles. The system lends itself to scalability, since the same substrate can easily accommodate an arbitrary number of traps. Moreover, the coupling strength is tunable and under experimental control. Our theoretical predictions take into account a realistic setting, within the reach of current technology.

Abstract: Fundamento. El insomnio es un problema frecuente en las personas que sufren enfermedades mentales. El personal de enfermería controla y registra si los pacientes duermen o no. El objetivo de este trabajo es analizar la concordancia entre las percepciones de los pacientes de una unidad psiquiátrica de agudos sobre la calidad de su sue o y las notas recogidas en el evolutivo de enfermería al respecto. Material y métodos. Estudio comparativo entre las respuestas dadas por pacientes de nuestra unidad a 126 cuestionarios sobre insomnio en noches concretas y lo reflejado en sus historias de enfermería. Se utilizó una versión reducida de la Escala Atenas de Insomnio (EAI-5). Resultados. El valor medio obtenido según las respuestas de los pacientes es superior (peor sue o) al dado por las enfermeras, tanto de manera global como por ítem. La historia de enfermería refleja valores mucho más bajos que los otorgados por el paciente, el análisis de correlación de Pearson proporcionó un coeficiente de 0,26. El análisis de grado de acuerdo proporcionó un ICC de 0,13 y no difiere de manera significativa al acuerdo nulo. Conclusiones. Hay discordancia entre las observaciones de enfermería y las sensaciones subjetivas de los pacientes sobre cómo duermen. Refieren dormir peor de lo que refleja la historia de enfermería. La observación externa y la autopercepción no son aspectos antagónicos, sino dos aspectos complementarios del sue o de los pacientes. Background.

Creation and manipulation of entanglement in spin chains far from equilibrium
F. Galve,D. Zueco,G. M. Reuther,S. Kohler,P. H?nggi
Physics , 2010, DOI: 10.1140/epjst/e2010-01220-5
Abstract: We investigate creation, manipulation, and steering of entanglement in spin chains from the viewpoint of quantum communication between distant parties. We demonstrate how global parametric driving of the spin-spin coupling and/or local time-dependent Zeeman fields produce a large amount of entanglement between the first and the last spin of the chain. This occurs whenever the driving frequency meets a resonance condition, identified as "entanglement resonance". Our approach marks a promising step towards an efficient quantum state transfer or teleportation in solid state system. Following the reasoning of Zueco et al. [1], we propose generation and routing of multipartite entangled states by use of symmetric tree-like structures of spin chains. Furthermore, we study the effect of decoherence on the resulting spin entanglement between the corresponding terminal spins.
