1001stories+ : An effective and affordable multi-media, multi-format communication framework for cultural heritage institutions

Negrini, Michela ; Paolini, Paolo (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2014 ; 2014COM013.

Over the last decade, there has been an increasing number of technologies and devices (including smartphones, tablets and alike) able to provide new perspectives for the use of multimedia applications in the field of Cultural Heritage. This work arises from the interest in providing better authoring/delivery possibilities to cultural heritage institutions (small and medium sized in particular). ...

Abandon ship? : party brands and politicians’ responses to a political scandal

Daniele, Gianmarco ; Galletta, Sergio ; Geys, Benny

In this article, we study politicians’ – rather than voters’ – responses to the main political scandal in Italian recent history (Tangentopoli), and overcome endogeneity concerns by analysing the local implications of this national corruption scandal. We find that local politicians withdraw support for incumbents in parties hit by Tangentopoli – inducing increased political...

Accounting based valuation and implied discount factor

Brughelli, Moreno ; Barone-Adesi, Giovanni (Dir.)

Thèse de doctorat : Università della Svizzera italiana, 2012 ; 2012ECO003.

The focus of this doctoral thesis is on the determination of the implied cost of capital in the equity market. Three issues are investigated in detail: the relations between the cost of equity capital, the credit spread and the economic growth; the links between realized market returns and the cost of capital; and the forecasting power of the implied discount factor in predicting market...

Accounting for WTP/WTA discrepancy in discrete choice models : discussion of policy implications based on two freight transport stated choice experiments

Masiero, Lorenzo ; Maggi, Rico

A key input in cost-benefit analysis is represented by the marginal rate of substitution which expresses the willingness to pay, or its counterpart willingness to accept, for both market and non-market goods. The consistent discrepancy between these two measures observed in the literature suggests the need to estimate reference dependent models able to capturing loss aversion by...

Accuracy of performance counter measurements

Zaparanuks, Dmitrijs ; Jovic, Milan ; Hauswirth, Matthias

Many workload characterization studies depend on accurate measurements of the cost of executing a piece of code. Often these measurements are conducted using infrastructures to access hardware performance counters. Most modern processors provide such counters to count micro-architectural events such as retired instructions or clock cycles. These counters can be diffocult to configure, may not be...

Accurate short-term yield curve forecasting using functional gradient descent

Audrino, Francesco ; Trojani, Fabio

In: Journal of financial econometrics, 2007, vol. 5, no. 4, p. 591–623

We propose a multivariate nonparametric technique for generating reliable shortterm historical yield curve scenarios and confidence intervals. The approach is based on a Functional Gradient Descent (FGD) estimation of the conditional mean vector and covariance matrix of a multivariate interest rate series. It is computationally feasible in large dimensions and it can account for non- linearities...

ACKR3 expression on diffuse large B cell lymphoma is required for tumor spreading and tissue infiltration

Puddinu, Viola ; Casella, Sabrina ; Radice, Egle ; Thelen, Sylvia ; Dirnhofer, Stefan ; Bertoni, Francesco ; Thelen, Marcus

In: Oncotarget, 2017, vol. 8, no. 49, p. 85068-85084

Diffuse large B cell lymphoma (DLBCL) is the most frequent lymphoma accounting for more than the 30% of the cases. Involvement of extranodal sites, such as bone marrow and central nervous system, is associated with poor prognosis. A contribution of the chemokine system in these processes is assumed as it is known as a critical regulator of the metastatic process in cancer. The atypical...
