Estrategias de gestión del valor añadido en las recesiones económicas: Análisis configuracional en las empresas de la industria cárnica española
2023
El objetivo de esta tesis doctoral es analizar las estrategias de gestión y recuperación de valor añadido en las recesiones económicas. Este estudio conecta la literatura académica sobre gobernanza de los stakeholders, sobre gestión de crisis y resiliencia empresarial con el análisis del valor añadido generado. En concreto, llevamos a cabo un estudio exploratorio de las estrategias de éxito y las estrategias fallidas para la recuperación de valor añadido tras una crisis, tomando especial atención a la gobernanza de los stakeholders, gestionando la diversidad en la distribución y llevando a cabo reajustes en el valor añadido asignado a las diferentes partes interesadas durante …
Design and protocol of Estrogenic Regulation of Muscle Apoptosis (ERMA) study with 47 to 55-year-old women's cohort : novel results show menopause-re…
2018
Objective: The multidisciplinary Estrogenic Regulation of Muscle Apoptosis (ERMA) study was designed to reveal how hormonal differences over the menopausal stages affect the physiological and psychological functioning of middle-aged women. This paper describes the protocol and nonrespondent analysis of ERMA and novel findings on menopausal differences in blood count variables and their association with female sex hormones. Methods: Women aged 47 to 55 years were assigned to pre, early peri, late peri, and postmenopausal groups based on follicle-stimulating hormone (FSH) and bleeding diary. Multivariate linear regression models were constructed to estimate the association of 17b-estradiol (E…
Critical proofreading of the book "Les derniers jours du siège d'Alésia"
2023
Was there a lunar eclipse that could have influenced the outcome of the Battle of Alesia? This is the argument developed in the book by Alain Deyber and David Romeuf, «Les Derniers Jours du Siège d'Alésia». Having verified the existence of an eclipse on the date given by the authors and based on the latest publications as well as on the scientific consensus, we conduct a critical study on the chronology of the siege and on the ethnological arguments, even ethno-astronomical of the authors.
FLUMO: FLexible Underwater MOdem
2019
The last years have seen a growing interest in underwater acoustic communications because of its applications in marine research, oceanography, marine commercial operations, the offshore oil industry and defense. High-speed communication in the underwater acoustic channel has been challenging because of limited bandwidth, extended multipath, refractive properties of the medium, severe fading, rapid time variation and large Doppler shifts. In this paper, we show an implementation of a flexible Software-Defined Acoustic (SDA) underwater modem, where modulation parameters are completely tunable to optimize performance. In particular, we develop the system architecture following two key ideas. …
INTERNATIONAL FINANCING ALTERNATIVES FOR ROMANIAN CENTRAL GOVERNMENT
2011
At present all world countries are seeking to attract the cheapest way of public resources needed to cover budget deficits. This paper aims to review the five alternatives for external funding of countries faced with insufficient public funds to the state budget. It focuses on the possibilities of financing with borrowed resources. The financing alternatives are presented from the perspective of Romania's access to them, with comparative references to other European Union member states. International funding alternatives are: loans from the International Monetary Fund, World Bank, European Commission, European Bank for Reconstruction and Development, European Investment Bank.
El cuerpo materno en la red: entre el orden de lo ?deseable? y el de lo real
2019
El estilo de vida fitness se realiza en, y a través de, un entramado subjetivo y de poder en el que circulan y se ensamblan dispositivos empresariales, terapéuticos, sanitarios y de espectacularización de los cuerpos, tendientes a inscribir la vida de la población en las tramas conflictivas de un capitalismo heterosexista, neoliberal e informacional. En dicho marco, la temporalidad, metamorfosis y plasticidad del cuerpo materno irrumpe como problema y objeto de intervención de tecnologías diversas orientadas a ajustar su tamaño, forma y devenir a los parámetros de la vida activa y saludable. En escenarios digitales, dicha tensión se materializa, por un lado, a través de dispositivos visuale…

Maternal antibody transmission and breeding densities in the Black-headed Gull Larus ridibundus
2004
1. The offspring of avian species, especially those of colonial breeders, are exposed to a number of pathogens immediately after birth. The chick's immune system is, at that early stage still immature and inefficient. As a consequence, diseases can have a strong impact on chick survival.2. The ability of mothers to transmit passive immunity in terms of antibodies of their own acquired immunity to their chicks is probably an essential pathway to enhance the chick survival. Since the production of antibodies is costly, females are expected to adjust the transmission of passive immunity to the local disease environment.3. We found that in Black-headed Gulls (Larus ridibundus L.) yolk antibody …
Transgenerational immunity in a bird-ectoparasite system: do maternally transferred antibodies affect parasite fecundity or the offspring's susceptib…
2009
During egg formation, female birds deposit antibodies against parasites and pathogens they were exposed to before egg laying into the yolk. In captive bird species, it has been shown that these maternal immunoglobulins (maternal yolk IgGs) can protect newly hatched offspring against infection. However, direct evidence for such benefits in wild birds is hitherto lacking. We investigated (1) if nestling Great Tits Parus major originating from eggs with naturally high levels of maternal yolk IgG are less susceptible to a common, nest-based ectoparasite, (2) if maternal yolk IgGs influence nestling development and in particular, their own immune defence, and (3) if there is a negative correlati…
Antibody injection in the egg yolk: maternal antibodies affect humoral immune response of the offspring
2010
Summary 1. In vertebrate species, maternal antibodies specific for the pathogens to which mothers have been exposed can be transmitted to offspring before birth. This is assumed to be adaptive as these antibodies can be essential in protecting offspring early in life before their own immune system is fully developed. However, fitness consequences in natural conditions and the long-term effects of these mechanisms have yet to be fully examined. 2. Exploring the ecological and evolutionary implications of such maternal effects requires experimental manipulations to avoid potential confounding maternal effects. In birds, maternal antibodies are transmitted via the egg yolk – a self contained e…
