Behavioral premium principles
We define a premium principle under the continuous cumulative prospect theory which extends the equivalent utility principle. In prospect theory, risk attitude and loss aversion are shaped via a value function, whereas a transformation of objective probabilities, which is commonly referred as probability weighting, models probabilistic risk perception. In cumulative prospect theory, probabilities of individual outcomes are replaced by decision weights, which are differences in transformed, through the weighting function, counter-cumulative probabilities of gains and cumulative probabilities of losses, with outcomes ordered from worst to best. Empirical evidence suggests a typical inverse-S shaped function: decision makers tend to overweight small probabilities, and underweight medium and high probabilities; moreover, the probability weighting function is initially concave and then convex. We study some properties of the behavioral premium principle. We also assume an alternative framing of the outcomes; then, we discuss several applications to the pricing of
insurance contracts, considering different value functions and probability weighting functions proposed in the literature, and an alternative mental accounting. Finally, we focus on the shape of the probability weighting function

Free and combined L- and D-amino acids in Arctic aerosol
Aerosol samples were collected with a high-volume cascade impactor with a 10 day sampling frequency at the Gruvebadet observatory, close to Ny-Ålesund (Svalbard Islands). A total of 42 filters were analyzed for free and combined amino acids, as they are key components of bio-aerosol. This article provides the first investigation of free and combined L- and d-amino acids in Arctic atmospheric particulate matter. The main aim of this study was to determine how these compounds are distributed in size-segregated aerosols after short-range and long-range atmospheric transport and understand the possible sources of amino acids. The total load of free amino acids ranged from 2.0 to 10.8 pmol m-3, while combined amino acids ranged from 5.5 to 18.0 pmol m-3. At these levels amino compounds could play a role in the chemistry of cloud condensation nuclei and fine particles, for example by influencing their buffering capacity and basicity. Free and combined amino acids were mainly found in the fine aerosol fraction (<0.49 μm) and their concentrations could be affect by several sources, the most important of which were biological primary production and biomass burning
On the cardinal system in Italian Sign Language (LIS)
This paper offers a comprehensive discussion of the cardinal system of Italian Sign
Language (LIS). At the lexical level, we present the different formational strategies used to
generate cardinal numerals and we provide evidence that in the younger generations of
signers, the sign ONE has lost the function of indefinite determiner and is now used as
cardinal only. At the syntactic level, we show that the attested variation in order between
the cardinal and the noun is in part due to definiteness and contrastive focus. We account
for this variation within the cartographic approach to syntax. Finally, we offer a principled
explanation for the reason why cardinals inside Measure Phrases are not subject to word
order variation, but always precede the measure noun
