Il nesso di causalità

2018

The essay deals with the issue of causation in private law, referring to the broad debate that commits the scholars of criminal law. The basic idea is that in the area of private law, both in the law in action and in the reflections of the doctrine, the causal judgment must be conducted more rigorously. The study proposes to apply in a more inflexible way the model of judgment already experimented in criminal law, corrected with the necessary adaptations to the characteristics of liability in private law and of the civil trial. The proposed model is structured on two levels: the general one of a nomologicaldeductive nature (general causation) and the other concrete one based on logical prob…

A prospective, multi-center, practice-based cohort study on all-ceramic crowns

2021

The aim of this prospective, multi-center, practice-based cohort study was to analyze factors associated with the success of all-ceramic crowns.All-ceramic crowns placed in a practice-based research network ([Ceramic Success Analysis, AG Keramik) were analyzed. Data from 1254 patients with (mostly in-office CAD/CAM) all-ceramic crowns placed by 101 dentists being followed up for more than 5 years were evaluated. At the last follow-up visit crowns were considered as successful (not failed) if they were sufficient, whereas crowns were considered as survived (not lost) if they were still in function. Multi-level Cox proportional hazards models were used to evaluate the association between a ra…

Are pelvic side-wall recurrences of cervical cancer biologically different from central relapses?

1994

Background. By using the Combined Operative and Radiotherapeutic Treatment (CORT) procedure, pelvic side-wall recurrences of gynecologic malignancies arising in a previously irradiated pelvis may be locally controlled. Local control of central relapses may be achieved by exenteration alone. If, in cervical cancer, both relapse patterns are biologically different (as hypothesized by some investigators), distinct disease courses after local treatment may be expected. Methods. Since June, 1989, 32 pelvic recurrences of cervical cancer were treated for local control in this institution. The median size of the recurrent tumors was 5 cm (range, 2–9 cm); 84% of the patients had been extensively ir…

Chemotherapy and Hepatic Steatosis: Impact on Postoperative Morbidity and Survival after Liver Resection for Colorectal Liver Metastases

2020

<b><i>Background:</i></b> Hepatic steatosis and chemotherapy in the treatment of colorectal liver metastases (CLM) are often linked to increased mortality and morbidity after liver resection. This study evaluates the influence of macrovesicular hepatic steatosis and chemotherapeutic regimes on graded morbidity and mortality after liver resection for CLM. <b><i>Methods:</i></b> A total of 323 cases of liver resection for CLM were retrospectively analysed using univariable and multivariable linear, ordinal and Cox regression analyses. The resected liver tissue was re-evaluated by a single observer to determine the grade and type of hepatic steat…

Identification of stiffness, dissipation and input parameters of multi degree of freedom civil systems under unmeasured base excitations

2009

A time domain dynamic identification technique based on a statistical moment approach has been formulated for civil systems under base random excitations in the linear state. This technique is based on the use of classically damped models characterized by a mass proportional damping. By applying the Itô stochastic calculus, special algebraic equations that depend on the statistical moments of the response can be obtained. These equations can be used for the dynamic identification of the mechanical parameters that define the structural model, in the case of unmeasured input as well, and the identification of the input itself. Furthermore, the above equations demonstrate the possibility of id…

Adaptive trial design: a general methodology for censored time to event data.

2008

Adaptive designs allow a clinical trial design to be changed according to interim findings without inflating type I error. The Inverse Normal method can be considered as an adaptive generalization of classical group sequential designs. The use of the Inverse Normal method for censored survival data was demonstrated only for the logrank statistic. However, the logrank statistic is inefficient in the presence of nuisance covariates affecting survival. We demonstrate, how the Inverse Normal method can be applied to Cox regression analysis. The required independence between test statistics of the different stages of the trial can be obtained by two different approaches. One is using the indepen…

A Nomogram-Based Prognostic Model for Advanced Hepatocellular Carcinoma Patients Treated with Sorafenib: A Multicenter Study

2021

Simple Summary Accurate prognostic systems capable of predicting the survival of patients with advanced hepatocellular carcinoma undergoing Sorafenib therapy are still lacking. The search for the ideal predictive tool for survival and drug response is justified by the recent availability of several other drugs effective for these patients, licensed as first- and second-line treatment, other than reducing adverse events and costs. In this study, we aimed to identify simple demographic and clinical parameters able to predict survival and Sorafenib response in a large multicenter cohort. In this study, we showed that patient’s general status, liver function and damage laboratory parameters and…

Best not to bet on the horserace: A comment on Forrin and MacLeod (2017) and a relevant stimulus-response compatibility view of colour-word contingen…

2018

International audience; One powerfully robust method for the study of human contingency learning is the colour-word contingency learning paradigm. In this task, participants respond to the print colour of neutral words, each of which is presented most often in one colour. The contingencies between words and colours are learned, as indicated by faster and more accurate responses when words are presented in their expected colour relative to an unexpected colour. In a recent report, Forrin and MacLeod (2017b, Memory & Cognition) asked to what extent this performance (i.e., response time) measure of learning might depend on the relative speed of processing of the word and the colour. With keypr…

Case of Monopolies at Stake

2005

In this chapter, our purpose is to illustrate the complexity of the outcomes of technological change and the concerns of regulators in the European gambling markets. In 2002, the Finnish Betting and Tipping Company, Veikkaus, estimated, that Finns’ Internet gambling decreased its turnover of betting by 10%. Such leakage is a reason why politicians in different states are considering imposing restrictions of online gambling to other parties of the gambling process, such as Internet service providers, banks, and credit card companies. On the other hand, one possible way to caulk the leakage could be to improve the returns of the players, but this has an adverse effect on the social and politi…

How Electoral Institutions Change the Influence of World Trade Integration on Trade Policies

2014

World integration levels influence opportunity costs of maintaining restrictive national trade policies. In an integrated world, restrictive trade policies are more costly than in a context of low overall levels of world market integration. We argue that policy makers can be expected to react to these varying incentives to liberalize the trade regimes of their countries, yet do so not in a uniform fashion across countries. Rather, the responsiveness to changes in levels of world trade integration is conditional upon the electoral system the country in question employs. This is due to the fact that opportunity cost considerations increase in importance with a) the degree to which policy make…
