Application of an interspecific competition model to predict the growth of Aeromonas hydrophyla on fish surfaces during refrigerated storage (Anwendu…
2007
The growth of Aeromonas hydrophila and the aerobic mesophilic plate count (APC) on gilthead seabream surfaces was evaluated during refrigerated storage (21 days). The related growth curves were compared with those obtained by a conventional third order predictive model obtaining a low agreement between observed and predicted data (Root Mean Squared Error = 1.77 for Aeromonas hydrophila and 0.64 for APC).The Lotka-Volterra interspecific competition model was used in order to calculate the degree of interaction between the two bacterial populations (beta_{Ah/APC} and beta_{APC/Ah}, respectively, the interspecific competition coefficients of APC on Aeromonas hydrophila and vice-versa). Afterwa…
The globalisation divide in the public mind: belief systems on globalisation and their electoral consequences
2019
Many studies describe how globalisation—the global integration of the economic, political, and cultural domains of society—transforms party competition in Western Europe. At the citizen level, however, our knowledge about globalisation attitudes and their electoral consequences remains limited. Using data from a large-scale panel survey of the German public, we show that, first, citizens hold stable rather than fluid attitudes towards the concept of globalisation. Second, these attitudes are rather closely related to positions on specific economic, cultural, and political issues that social scientists understand as facets of globalisation but unrelated to positions on traditional redistribu…
The dynamics of privatization and regulation of water services: a comparative study of two Spanish regions
2013
As in other economic activities, privatization of water delivery has not resulted in the retreat of the public sector, but rather a change in the way in which the government intervenes in the water industry. This paper illustrates this situation by comparing urban water services in two Spanish regions, Andalusia and Catalonia. Water service delivery is structured very differently in these two regions with respect to private involvement, the degree of market concentration and, as a result, problems in competition. The characteristics of the two regions' respective regulatory agencies reflect the different paths taken to privatization: in Catalonia private firms have much more tradition and o…
NATIONAL AGENCIES IN THE EUROPEAN ADMINISTRATIVE SPACE: GOVERNMENT DRIVEN, COMMISSION DRIVEN OR NETWORKED?
2009
Submitted version of an article published in the journal: Public Administration. Published version available at Wiley InterScience: http://dx.doi.org/10.1111/j.1467-9299.2009.01779.x In terms of national agencies in the European administrative space, case studies indicate that national governments may be partly split so that national (regulatory) agencies operate in a 'double-hatted' manner when practising EU legislation, serving both ministerial departments and the European Commission. Applying large-N questionnaire data, this article follows up these studies by investigating how important various institutions are with respect to influencing national agencies when they are practising EU le…
Dominance of wine Saccharomyces cerevisiae strains over S. kudriavzevii in industrial fermentation competitions is related to an acceleration of nutr…
2019
Grape must is a sugar‐rich habitat for a complex microbiota which is replaced by Saccharomyces cerevisiae strains during the first fermentation stages. Interest on yeast competitive interactions has recently been propelled due to the use of alternative yeasts in the wine industry to respond to new market demands. The main issue resides in the persistence of these yeasts due to the specific competitive activity of S. cerevisiae. To gather deeper knowledge of the molecular mechanisms involved, we performed a comparative transcriptomic analysis during fermentation carried out by a wine S. cerevisiae strain and a strain representative of the cryophilic S. kudriavzevii, which exhibits high genet…
Competitive interactions in insect parasitoids: effects of microbial symbionts across tritrophic levels
2023
Competition for hosts is a common ecological interaction in insect parasitoids. In the recent years, it has become increasingly evident that microorganisms can act as ‘hidden players’ in parasitoid ecology. In this review, we propose that parasitoid competition should take into consideration the microbial influence. In particular, we take a tritrophic perspective and discuss how parasitoid competition can be modulated by microorganisms associated with the parasitoids, their herbivore hosts, or the plants attacked by the herbivores. Although research is still in its infancy, recent studies have shown that microbial symbionts can modulate the contest outcome. The emerging pattern is that micr…
Factors Influencing the Choice of Higher Education Establishment for Marketing Strategies of Higher Education
2015
Abstract The world-wide competition of higher education programs makes education institutions to seek for most efficient ways to attract students. The presented academic research is devoted also to the issues on motives and influencing factors for the choice of study programs. The methods applied in the current paper are as follows: analysis of scientific publications, focus group discussions, surveys of possible future students. For the evaluation of different aspects of choice a scale of 1-10 was used. For the data analysis of the survey descriptive statistical analysis, cross tabulations and correlation analysis, as well as analysis of variance (ANOVA) and factor analysis were applied.
The joint evolution of learning and dispersal maintains intraspecific diversity in metapopulations
2021
The evolution of dispersal tendencies and of cognitive abilities have both been intensely studied. Yet little attention has been given to the question of how these two aspects may relate to each other, as a result of their joint evolution. On the one hand, learning abilities may help dispersers to cope with their new habitat. On the other hand, dispersal may sometimes reduce the need for learning, because local environments may differ in how much there is to learn. To get a better understanding of this relationship, we built an individual‐based simulation in which both learning speed and dispersal tendency were free to evolve. We found that both positive and negative correlations could evol…

Resting the mind – A novel topic with scarce insights. Considering potential mental recovery strategies for short rest periods in sports
2019
Abstract Both meticulously structured trainig routine as well as specific characteristics of various sports (e.g., swimming, shooting, modern pentathlon) with multiple competition bouts in a single day appear to be mentally demanding and may result in a state of mental fatigue. Due to these multidimensional demands, adequate training and competition recovery is essential. Consequently, the idea of mental recovery embraces the spotlight of research. On training and competition days, short rest periods implemented as a vital part, can be used for mental recovery and can help in assisting athletes to return to baseline levels of mental abilites (e.g., concentration, attention). Sport-specific …
