Ordinary (p_1,...,p_m)-Laplacian system with mixed boundary value

2016

In this paper we prove the existence of multiple weak solutions for an ordinary mixed boundary value system with (p_1,...,p_m)-Laplacian by using recent results of critical points.

Sequentially Forecasting Economic Indices Using Mixture Linear Combinations of EP Distributions

2021

This article displays an application of the statistical method moti- vated by Bruno de Finetti's operational subjective theory of probability. We use exchangeable forecasting distributions based on mixtures of linear com- binations of exponential power (EP) distributions to forecast the sequence of daily rates of return from the Dow-Jones index of stock prices over a 20 year period. The operational subjective statistical method for comparing distributions is quite different from that commonly used in data analysis, because it rejects the basic tenets underlying the practice of hypothesis test- ing. In its place, proper scoring rules for forecast distributions are used to assess the values o…

A Fatal Bloodstream Infection byStaphylococcus pettenkoferiin an Intensive Care Unit Patient

2011

Coagulase negative staphylococci are increasingly recognized as leading pathogens in bacteremia, with incidence peaking in intensive care units. Interpretation of blood cultures that are positive for CoNS is often doubtful. We describe a fatal case of bacteremia by a newly recognized species of CoNS,Staphylococcus pettenkoferi, in an ICU patient.

Tonometers and infectious risk: myth or reality? Efficacy of different disinfection regimens on tonometer tips

2006

Purpose To evaluate the adequacy of common disinfection regimens for disposable tonometer tips and assess if disinfection of reusable prisms or the use of disposable tips is preferable. Methods We used disposable tonometer tips, using the same material and tip diameter of standard Goldmann tonometer prism. Strains of Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis and Candida albicans were tested according to the European standard guidelines for disinfectants test. Antimicrobial effectiveness of the following disinfection practices has been assessed: dry wipe, Minuten wipes (Alpros), soaking in 3% hydrogen peroxide, 0.5% benzalkonium chloride, and 0.5% Pantasepts for 1, 5, …

Ketogenic diet, physical activity, and hypertension—a narrative review

2021

Several studies link cardiovascular diseases (CVD) with unhealthy lifestyles (unhealthy dietary habits, alcohol consumption, smoking, and low levels of physical activity). Therefore, the strong need for CVD prevention may be pursued through an improved control of CVD risk factors (impaired lipid and glycemic profiles, high blood pressure, and obesity), which is achievable through an overall intervention aimed to favor a healthy lifestyle. Focusing on diet, different recommendations emphasize the need to increase or avoid consumption of entire classes of food, with only partly known and only partly foreseeable consequences on the overall level of health. In recent years, the ketogenic diet (…

Growth Volatility and the Structure of the Economy

2011

The aim of the chapter is twofold: (i) to propose a methodology to compute the growth rate volatility of an economy and (ii) to investigate the relationship between growth volatility and economic development through the lenses of the structural characteristics of an economy. We study a large cross-section of countries in the period 1970–2009, controlling for the stability of the estimates in two subperiods: 1970:1989 (Period I) and 1990:2009 (Period II). Our main findings are (i) the degree of trade openness has a destabilizing effect, while the degree of financial openness has not a significant effect; (ii) the size of the public sector displays a U-shaped relationship with growth volatili…

Religione, Fiducia e Comportamenti economici

2012

Nell'ambito del progetto Prin 2007, Religioni, democrazia economica e cooperazione nello spazio euro mediterraneo. Partenariato e buone prassi, l’attenzione del contributo è rivolto ad analizzare i legami tra scienza economica e religione. Si osserva come un elemento spesso dimenticato è la fiducia anche per il rinforzo sulle motivazioni intrinseche e materiali del comportamento dell’individuo e nel contesto sociale in cui opera. Le religioni hanno elementi comuni e spiegano diverse problematiche economiche prima fra tutte le relazioni di natura creditizia che –come prima indicato-hanno nella natura fiduciaria un elemento di stabilità come anche le attuali crisi finanziarie hanno dimostrato…

Design and analysis of discrete choice experiments for models with response time

2013

Settore SECS-S/02 - Statistica Per La Ricerca Sperimentale E TecnologicaA sector of conjoint analysis (experimental design in marketing research) is made of the so called choice experiments. In choice experiments respondents undergo a questionnaire which is nowadays mostly submitted through the internet. The questionnaire proposes to the respondent a sequence of choice sets each one including two or more profiles being a profile a specific combination of attribute levels. The respondent selects the preferred profile for each choice set. Responses given by a sample of respondents are analysed through suitable methods aimed to eventually find the best combination of attribute levels. One method of analysis adopts the Multinomial Logit (MLN) model. In this article the authors show the results of the MLN analysis compared with another model of analysis which uses an additional response which can be easily recorded by electronically submitted questionnaires. In practice modern survey platforms like “Qualtrics” (the one used for this work) can record the so called “response latency” i.e. the time taken by the respondent to make the choice and select the most preferred profile in the choice set. Thanks to a response latency model further refined in this work it is possible to deduce the relative weight of importance of the profiles for each choice set and respondent. This type of response can be used in place of the dichotomous choice variable in the MLN model. The two models and methods of analysis are deeply compared and it is critically discussed when it is better to use one or the other method. As a result a more reliable estimate of the optimal profile comes up implying lower risks for new investments and marketing decisions.
