Improving Estimates Accuracy of Voter Transitions. Two New Algorithms for Ecological Inference Based on Linear Programming

2022

The estimation of RxC ecological inference contingency tables from aggregate data is one of the most salient and challenging problems in the field of quantitative social sciences, with major solutions proposed from both the ecological regression and the mathematical programming frameworks. In recent decades, there has been a drive to find solutions stemming from the former, with the latter being less active. From the mathematical programming framework, this paper suggests a new direction for tackling this problem. For the first time in the literature, a procedure based on linear programming is proposed to attain estimates of local contingency tables. Based on this and the homogeneity hypot…

Advances in ventilatory treatment for OSAS

2021

Continuous positive airway pressure (CPAP) is the most widely used treatment for obstructive sleep apnea (OSA), and was established four decades ago. An alternative option is to use bilevel ventilation, in order to improve compliance to treatment especially in patients who need a high therapeutic pressure to prevent nocturnal respiratory events. Automatic CPAP or bilevel ventilation are also established among OSA therapeutic choices, and are generally indicated in cases of highly variable therapeutic pressure. The major advances in the field regard OSAS in the context of uncomplicated obesity hypoventilation syndrome (OHS), in which either CPAP or bilevel ventilation yield comparable result…

Uniformly Path Connected Homogeneous Continua

2016

It is proven that every path connected homogeneous continuum is uniformly path connected, which answers a question of David P. Bellamy. From this result it follows that every path connected homogeneous continuum is continuously equivalent either to an arc, or to the Cantor fan.

Real-world experience with obeticholic acid in patients with primary biliary cholangitis

2021

Background & aims Obeticholic acid (OCA) is the second-line treatment approved for patients with primary biliary cholangitis (PBC) and an inadequate response or intolerance to ursodeoxycholic acid. We aimed to evaluate the effectiveness and safety of OCA under real-world conditions. Methods Patients were recruited into the Italian PBC Registry, a multicentre, observational cohort study that monitors patients with PBC at national level. The primary endpoint was the biochemical response according to Poise criteria; the secondary endpoint was the biochemical response according to normal range criteria, defined as normal levels of bilirubin, alkaline phosphatase (ALP), and alanine aminotransfer…

Female reproductive factors are associated with objectively measured physical activity in middle-aged women

2017

Physical activity improves health and may delay the onset of several chronic diseases. For women in particular, the rate of these diseases accelerates at middle age; therefore it is important to identify the determinants of health-enhancing physical activity during midlife in this population. In this study, we focused on determinants that are unique to the female sex, such as childbearing and menopause. The main objective was to characterize the level of physical activity and differences between active and inactive middle-aged Finnish women. In addition, we examined the association of physical activity with female reproductive factors at midlife. The study population consisted of 647 women …

Valoración contingente del patrimonio cultural: ¿siguen siendo válidos los viejos axiomas en época de crisis?

2015

El patrimonio histórico cultural tiende, cada vez más, a ocupar un lugar en el espacio territorial, como un input relevante y vector del desarrollo local. Como muestran cada vez más estudios la conexión entre cultura y desarrollo es compleja, pero las evidencias nos indican que, los elementos patrimoniales pueden activar procesos de dinamización socioeconómica de formas diversas, y entre ellas a través del turismo cultural. Es por ello que las decisiones públicas y privadas sobre qué preservar resultan estratégicas y afectan a la capacidad de transformación del territorio, no sólo en las grandes intervenciones de carácter icónico, sino también en las intervenciones de menor dimensión y liga…

Progressive non-linear damage of variable angle tow composite plates by a Ritz approach

2022

In this work a Ritz model for progressive non-linear damage analysis of variable angle tow composite plates is presented. The damage is treated in the framework of continuum damage mechanics and its evolution is based on a linear softening law with which four damage indices are computed for degrading the mechanical properties of the material. A set of analyses have been carried out to investigate how damage evolves in VAT composite plates under progressive loading.

Diversity in warning coloration: selective paradox or the norm?

2019

Aposematic theory has historically predicted that predators should select for warning signals to converge on a single form, as a result of frequency-dependent learning. However, widespread variation in warning signals is observed across closely related species, populations and, most problematically for evolutionary biologists, among individuals in the same population. Recent research has yielded an increased awareness of this diversity, challenging the paradigm of signal monomorphy in aposematic animals. Here we provide a comprehensive synthesis of these disparate lines of investigation, identifying within them three broad classes of explanation for variation in aposematic warning signals: …

Incidentality on a continuum: A comparative conceptualization of incidental news consumption

2020

This article seeks to contribute to theorizing the dynamics of incidental news consumption. Through an analysis of 200 semi-structured interviews with people in Argentina, Finland, Israel, Japan, and the United States, we show that intentionality in news consumption can be viewed on a continuum, which goes from deliberately setting apart time to access the news on specific outlets to skimming through unsought-for news on social and broadcast media, with intermediate practices such as respondents setting up an environment where they are more or less likely to encounter news. Drawing on structuration theory, this article conceptualizes incidental news in the context of the wider media environ…
