Adequate policies and unintended effects in Spanish higher education
2000
Abstract Recent developments in Spanish higher education have been very positive. Universities have become autonomous and are more in tune to regional needs, their internal structure has become flexible, the whole system has become open and accessible, funds have been poured into the system as never before and market forces have started to play a relevant role. Nevertheless, some perverse effects have begun to emerge. We will focus on some of these negative aspects that deserve deeper consideration: the inadequate adaptation to a mass higher education system, and the negative consequences of the collegial model for governing universities and of regionalization.
Disengagement in work-role transitions
2010
The present study examines whether disengagement from previous work-roles positively predicts adaptation to a new work-role (here, becoming self-employed) by reducing negative consequences of psychological attachment to these previous roles. Disengagement involves an individual's effort to release attention from thoughts and behaviours related to the previous work-role. A three-wave longitudinal study investigated the relationship between psychological attachment (measured as affective commitment) to a prior work-role, disengagement from the prior work-role, and adaptation to a new work-role [pursuit of learning, fit perceptions with self-employment, task performance over time]. Participant…
The Moderating Role of Work-Related Rumination in Nurses’ Sleep Quality Trajectory During Morning Shift Work
2020
Abstract. This diary study investigated nurses’ recovery after transitioning to morning shift work (i.e., their short-term adaptation to shift work) by examining the change trajectory of sleep quality over the course of five consecutive morning shifts. Results of latent growth analyses ( N = 132) showed that nurses’ sleep quality started at low levels and increased rapidly in the beginning until it stabilized toward the end of the shift work period. Moreover, work-related rumination moderated the sleep quality trajectory. When rumination was low, nurses’ sleep quality showed a quadratic trajectory, whereas when rumination was high, sleep quality showed a flatter and linear trajectory, sugg…
A comparison of the marginal adaptation of composite overlays fabricated with silicone and an intraoral scanner
2021
Background Intraoral scanners have been developing during last years. The aim of this study was to know if digital impressions achieve a marginal adaptation in overlays as well as conventional impressions with silicone. Material and methods Sixty-two extracted molars were selected. The samples were prepared for MOD overlays. The teeth were divided into two groups (n=31). Group 1: impressions were made with silicone (Express™ Impression, 3M ESPE) and overlays were manufactured with Sinfony composite (3M ESPE) by the laboratory technician. Group 2: impressions were taken with the scanner True Definition (TD, 3M ESPE) and under Lava Ultimate CAD/CAM Restorative composite (3M ESPE) were produce…
Scanning electron microscopy of Antarctophthirus microchir (Phthiraptera: Anoplura: Echinophthiriidae): Studying morphological adaptations to aquatic…
2012
The members of the Family Echinophthiriidae (Phthiraptera: Anoplura) are unique among insects because they infest hosts with an amphibious lifestyle. During their evolution they developed morphological traits that are reflected in unique features. The SEM is a helpful tool to analyze them. Knowing in detail the external structure of these lice is the first step to understand the whole process that derived from the co-adaptation of lice and pinnipeds to the marine environment. For the first time, we studied the external structure of all stages of an echinophthiriid louse. The results are discussed in the light of their evolutionary, functional, and ecological implications.

The veridical perception of object temperature with varying skin temperature.
1988
The effect of skin-adaptation temperature on object-temperature perception was investigated, using the method of dichiric matching, in an attempt to determine whether veridical perception of physical object temperature occurs in human subjects. Observers were presented with a test temperature on one hand and required to find a matching temperature, that is, one that produced the same sensation, on the other, differently adapted, hand. Using equality of test and matching temperatures as a criterion of veridical perception, it was found that the latter improves with ΔT, the difference between object temperature and skin-adaptation temperature. It is postulated that when ΔT is close to zero, v…
Pilot study on stress and resilience in families with premature newborns
2014
Introduction: Prematurity is associated with severe clinical conditions, long hospital stays, and uncertainty about patient outcomes. These circumstances lead to a stressful situation that may affect family functioning. The aim of this study was to study risk and protection factors affecting family functioning in preterm as compared to healthy term infants. Population and methods: Preterm infants with and without pathological conditions (n = 40) were recruited at 24 months post-conception age, together with a control group of healthy term newborn infants (n = 31). Parents or usual caregivers responded to the Inventory of Family Protection Factors and Parental Stress scales. The results were…
How to develop strategies of adaptation to climate change based on a foresight exercise?
2019
Context and purpose of the study ‐ Prospective studies raise a real intellectual interest for those who contribute to them or take cognizance of it. But they are often considered too difficult to operationalize, and most of the prospective exercises are not followed by action plans, particularly at value chain level. To overcome this difficulty in linking the work of experts and the decisions of stakeholder of value chains, a particular effort was made to operationalize the outcomes from a prospective study on the French vine and wine industry in the context of climate change. The approach consisted in collecting and using the feed‐back of professionalsfrom the wine industry about these out…
Co-mimics have a mutualistic relationship despite unequal defences
2007
Defensive mimicry, where species have evolved to resemble others in order to evade predators, is quite common in the animal kingdom. The two extremes of the mimicry spectrum are known as 'batesian' and 'mullerian'. Batesian mimics develop signals — visual cues for instance — that are similar to those of species being mimicked, but stop short of adopting the attribute that makes it unprofitable prey to predators. Mullerian mimics both resemble the model species and share the anti-predation attribute — by being dangerous or unpalatable. These different types of mimic were identified a century ago, but the dynamics of mimicry between unequally defended prey remain unresolved. In an experiment …
Adaptive plasticity of blue tits(Parus caeruleus)and great tits(Parus major)breeding in natural and semi‐natural insular habitats
2004
The breeding performance and foraging of blue and great tits, and the abundance of arthropods living on the trees of an oak-wood and of a coniferous reafforestation were studied in Sicily, in order to: 1) compare breeding parameters in natural and semi-natural habitats within the same area; 2) estimate the degree of overlap in peak resource and peak demand of young tits, and the overlap of nestling diet of the two species in the two habitats. Both species had earlier laying dates, laid more eggs and raised more fledglings in the oakwood than in the reafforestation; they achieved the same fledging success within the same habitat type. These differences are probably due to the earlier and hig…
