Optimal quantum estimation of the Unruh-Hawking effect

We address on general quantum-statistical grounds the problem of optimal detection of the Unruh-Hawking effect. We show that the effect signatures are magnified up to potentially observable levels if the scalar field to be probed has high mean energy from an inertial perspective: The Unruh-Hawking effect acts like an amplification channel. We prove that a field in a Fock inertial state, probed via photon counting by a non-inertial detector, realizes the optimal strategy attaining the ultimate sensitivity allowed by quantum mechanics for the observation of the effect. We define the parameter regime in which the effect can be reliably revealed in laboratory experiments, regardless of the specific implementation.Comment: 4 pages, 2 figures.

The role of incidental variables of time in mood assessment

Determining what influences mood is important for theories of emotion and research on subjective well-being. We consider three sets of factors: activities in which people are engaged; individual differences; and incidental variables that capture when mood is measured, e.g., time-of-day. These three factors were investigated simultaneously in a study involving 168 part-time students who each responded 30 times in an experience sampling study conducted over 10 working days. Respondents assessed mood on a simple bipolar scale – from 1 (very negative) to 10 (very positive). Activities had significant effects but, with the possible exception of variability in the expression of mood, no systematic individual differences were detected. Diurnal effects, similar to those already reported in the literature, were found as was an overall “Friday effect.” However, these effects were small. Lastly, the weather had little or no influence. We conclude that simple measures of overall mood are not greatly affected by incidental variables.Affect; mood; experience sampling; diurnal effects; day-of-the-week; weather; multilevel analysis. leex

L'aula de ciències de secundària : de les tecnologies de la informació i la comunicació (TIC) a les tecnologies de l'aprenentatge i el coneixement (TAC), dels continguts a les competències

La utilització de les tecnologies de la informació i la comunicació és en l'actualitat un element essencial en l'adquisició de competències per part dels estudiants. Es tracta, en essència, de competències per convertir la informació en coneixement eficaç per guiar les accions, la qual cosa significa passar de les TIC (informació) a les TAC (coneixement)

Protected areas as a chance for the local development. The National Park of "Aigüestortes i Estany de Sant Maurici" as a dynamising element in its area of influence.

Recent times, many countries influenced by its citizens had followed a strategy of create natural or national parks. The overriding motive appears to be the preservation of a recognisable unique area of natural wealth. Nevertheless, recent years have seen a rising demand for wildlife viewing. In this sense, the demand of outdoor recreation in general and wildlife viewing in particular has grown rapidly. The problem is that too many visitors imply that the wilderness aspect of the recreational experience is watered down and second it affects the wildlife itself. The set of problems facing protected areas management has to do with the possibility of harmonising aims; preservation and recreational use. Generally, protected areas are settled on economically slum areas with high ageing rate, with important process of rural depopulation and under-staffed in terms of equipment, services and infrastructures. In this respect, a proper management of these natural areas could imply an economic and social revitalisation of such regions. This paper analyses the social and economic impact of the National Park of Aigüestortes i Estany de Sant Maurici on its influence zone. The Park is located in Catalonia in the heart of the Pyrenees and it's the most genuine representation of mountainous area. This paper analyses also the different alternatives that had been developed and considers others that could be introduced in order to achieve a greater complicity between local communities, visitors and managers by the reinforcement of the national park as a positive element for every one.
