Lack of association between celiac disease and dental enamel hypoplasia in a case-control study from an Italian central region
2007
Abstract Background A close correlation between celiac disease (CD) and oral lesions has been reported. The aim of this case-control study was to assess prevalence of enamel hypoplasia, recurrent aphthous stomatitis (RAS), dermatitis herpetiformis and atrophic glossitis in an Italian cohort of patients with CD. Methods Fifty patients with CD and fifty healthy subjects (age range: 3–25 years), matched for age, gender and geographical area, were evaluated by a single trained examiner. Diagnosis of oral diseases was based on typical medical history and clinical features. Histopathological analysis was performed when needed. Adequate univariate statistical analysis was performed. Results Enamel…
GW170817: Measurements of Neutron Star Radii and Equation of State
2018
On 17 August 2017, the LIGO and Virgo observatories made the first direct detection of gravitational waves from the coalescence of a neutron star binary system. The detection of this gravitational-wave signal, GW170817, offers a novel opportunity to directly probe the properties of matter at the extreme conditions found in the interior of these stars. The initial, minimal-assumption analysis of the LIGO and Virgo data placed constraints on the tidal effects of the coalescing bodies, which were then translated to constraints on neutron star radii. Here, we expand upon previous analyses by working under the hypothesis that both bodies were neutron stars that are described by the same equation…
Brief an Garlieb H. Merkel
1798
Ms. 930a, Nr. 12, Bl. 31r-34v Johannes Daniel Falk. Brief an Garlieb H. Merkel, Weimar, den 3. December 179[8?] Autora rokraksts / Autograph, vācu val. / Deutsch [8] lpp. / S. Attēlu numuri / Bildnummern: 930a-012-1, 930a-012-2-3, 930a-012-4-5, 930a-012-6-7, 930a-012-8 Im vorliegenden Brief vermischen sich private und berufliche Angelegenheiten sowie Klatsch miteinander. Nachdem Falk seine lange Antwortzeit zunächst damit begründet, dass er Merkels aktuelle Adresse nicht kenne, bringt er Neuigkeiten von der Krankheit einer nicht näher benannten Kammerrätin und nimmt an deren Leiden rege Anteil. Direkt im Anschluss präsentiert Falk den Stand seiner Verhandlungen mit Verlegern. Auch wenn Falk…
Minería de oro: promesas, conflictos y desilusión en Cerro de San Pedro, México
2018
Este artículo analiza los conflictos por los recursos agua y tierra en Cerro de San Pedro, México, cuando una empresa minera canadiense inició una mina a cielo abierto en este municipio. Examinamos diferentes posiciones en el conflicto entre la mina de oro y los habitantes locales, y cómo ambivalentes regulaciones nacionales y organismos gubernamentales permitieron que una empresa extranjera operara sin los permisos requeridos. Para analizar el conflicto utilizamos el marco de Escalones de Análisis de Derechos, que distingue cuatro capas de disputa: sobre los recursos; el contenido de las normas; el poder de decisión; y los discursos. Discutimos cómo la auto-representación de la empresa ext…
Risk factors for Lyme disease : A scale-dependent effect of host species diversity and a consistent negative effect of host phylogenetic diversity
2021
Biodiversity can influence disease risk. One example of a diversity-disease relationship is the dilution effect, which suggests higher host species diversity (often indexed by species richness) reduces disease risk. While numerous studies support the dilution effect, its generality remains controversial. Most studies of diversity-disease relationships have overlooked the potential importance of phylogenetic diversity. Furthermore, most studies have tested diversity-disease relationships at one spatial scale, even though such relationships are likely scale dependent. Using Lyme disease as a model system, we investigated the effects of host species richness and phylogenetic relatedness on the…
Exclusión discursiva. Hacia un nuevo concepto de la exclusión social
2011
The term “social exclusion” has been converting into a buzzword in European social sciences in the last decade. But the double use of the notion, as a concept of social politics as well as a sociological concept is producing a blurring of its contents. The aim of this article is to offer an approach which is able to satisfy the theoretic requirements for an analytical sociological concept by making use of the concept of discursive exclusion. Therefore the text develops the notion of discursive exclusion based on the most recent findings about sociological discourse theory and its contributions to the understanding of the construction of social reality. The process of social exclusion has to…
Generalized ``transition probability''
1975
An operationally meaningful symmetric function defined on pairs of states of an arbitrary physical system is constructed and is shown to coincide with the usual “transition probability” in the special case of systems admitting a quantum-mechanical description. It can be used to define a metric in the set of physical states. Conceivable applications to the analysis of certain aspects of Quantum Mechanics and to its possible modifications are mentioned.
La participación en asociaciones de los inmigrantes africanos. Vías de interpretación del distanciamiento asociativo
2013
This article is focused on the reasons for non-participation of African population in immigrant associations. To understand this question, we conducted semi-structured interviews with persons who decided consciously no to participate in associations and organizations that worked with immigrants. All this work was developed in Catalonia, Valencia and Navarra, from a multilocal research perspective. We interpret the associative detachment, as a voluntary distancing based on the absence of information, lack of time, disenchantment, proprietorship activism, passively waiting, or because they are the only user population. Nevertheless, there are other factors of greater significance, as the poli…
Por mis hijos lo que sea... o casi. Identidades de madres y padres que han vivido un divorcio
2014
A partir de los discursos de personas divorciadas o separadas (de generaciones nacidas entre 1965 y 1975), se analiza la configuración de las identidades parentales. El divorcio implica reorganizar aspectos relativos al cuidado de hijos/as, favoreciendo la reflexión sobre la propia identidad parental. Nuestra hipótesis problematiza los resultados de Solsona y Ferrer (2010), quienes destacan la centralidad del hecho de ser madres y padres entre las generaciones mayores. Destacan entre los resultados que las mujeres reubican la maternidad al mismo nivel de importancia que otros aspectos de sus trayectorias vitales, mientras que los hombres tienden a idealizar la paternidad.; From the discours…
Trabajo no remunerado y trabajo negro en España
2005
enric.sanchis@uv.es El trabajo irregular y el no remunerado tienen una importancia considerable en el Estado español, por lo que el análisis de la estructura y evolución del empleo no puede hacerse al margen de ellos. En este artículo se ofrece una visión de conjunto de ambos fenómenos a partir de algunas de las investigaciones llevadas a cabo durante los últimos años. Casi la totalidad del trabajo no remunerado se hace en el ámbito de las relaciones familiares. Se calcula que dos tercios de la carga total de trabajo que soporta la economía española es trabajo doméstico no remunerado, mayoritariamente hecho por mujeres. No obstante, el trabajo voluntario no familiar equivale aproximadamente…
