Hair Cortisol Concentration as a Biomarker of Sleep Quality and Related Disorders
2021
Cortisol is the end product of the hypothalamic-pituitary-adrenal (HPA) axis, and its production is increased mainly in stressful situations or in chronic disorders accompanied by stress enhancement. Altered cortisol concentrations have been reported in a number of neuropsychiatric diseases and sleep disorders. Cortisol concentrations have been measured using several methods, and in several matrixes, such as blood, saliva, and urine. However, lately, hair cortisol, for several reasons, has emerged as a promising biomarker of long-term retrospective HPA activation. Several experimental approaches for cortisol measurement with the corresponding concentration reference ranges and a summary of …
The good, the bad and the ugly: images of the foreigner in contemporary criminal law
2018
Since the end of the Second World War, the criminal law of Western states has tried to legitimate itself, in basically democratic-republican terms, as primarily addressed towards citizens. During approximately the last 20 years, however, new dimensions of criminal law have emerged, which refer paradigmatically (not to the citizen, but) to the foreigner and subject him/her to worse legal treatment than that which is considered legitimate when either citizens or ‘good’ foreigners are concerned. Next to the ideal-type of the citizen criminal law (also applicable, by assimilation, to the ‘good’ foreigner) a criminal law for ‘ugly’ mass-foreigners (crimmigration) and one for ‘bad’ foreigners (en…
CLAYS IN COSMETICS AND PERSONAL-CARE PRODUCTS
2021
Clays are used in various cosmetic formulations, such as sunscreens, toothpastes, deodorants, creams, hair cosmetics, makeups, nail polish, facial masks, and shampoos, among others, to improve the organoleptic and physicochemical characteristics, to increase the stability, or to facilitate elaboration. Together with their technological functionalities, clays are cosmetologically active ingredients with cleaning, anti-aging, anti-wrinkling, and sun-care functionalities. Talc, kaolinite, mica, and some smectites are the clay minerals used most frequently in cosmetic products, but several other phyllosilicates as well as modified and synthetic clays are also used. Sometimes, clays are useful i…
Changes in Climate and Land Use Over the Amazon Region: Current and Future Variability and Trends
2018
This paper shows recent progress in our understanding of climate variability and trends in the Amazon region, and how these interact with land use change. The review includes an overview of up-to-date information on climate and hydrological variability, and on warming trends in Amazonia, which reached 0.6-0.7 °C over the last 40 years, with 2016 as the warmest year since at least 1950 (0.9 °C +0.3°C). We focus on local and remote drivers of climate variability and change. We review the impacts of these drivers on the length of dry season, the role of the forest in climate and carbon cycles, the resilience of the forest, the risk of fires and biomass burning, and the potential “die back” of …
Années arrosées et années sèches au Proche-Orient, relation avec la circulation atmosphérique régionale
2003
Les précipitations au Proche-Orient (Liban, Syrie, Jordanie, Territoire Autonome Palestinien, Israël) sont caractérisées par une grande variabilité, que ce soit à l’échelle interannuelle ou à l’échelle mensuelle. Pour cerner et expliquer cette variabilité, trois ensembles régionaux de co-variation ont été définis en utilisant les données mensuelles de 116 stations pour la période 1960-61/1989-90. Nous avons analysé la relation entre les années exceptionnellement arrosées ou sèches et la circulation atmosphérique régionale (données de réanalyses). Les précipitations dans les trois régions apparaissent très dépendantes de l’occurrence et de la position d’un talweg en altitude à l’est de la Mé…
Internet-based information and foreign direct investment (FDI) location decision making: An information cost perspective
2012
Published version of an article in the journal: African Journal of Business Management. Also available from the publisher at: http://dx.doi.org/10.5897/AJBM11.1203 Open Access Information and communication technology (ICT) is considered to play an important role to reduce information cost for potential foreign investors. While a growing body of literature has suggested such connections, conceptual clarity is yet to be achieved. This study introduces a conceptual framework based on the Information-theoretic approach and transaction cost perspective to explore how ICT may reduce information cost. To illustrate our proposed framework, we apply it to examine the role of Internet-based informati…
El model PROT i la responsabilitat social universitaria: prosocialitat i transferència del coneixement a la pràctica
2019
espanolEn 30 anos de historia, el grupo LIPA (Laboratorio de Investigacion Prosocial Aplicada) de la Universidad Autonoma de Barcelona (UAB) ha promovido y generado un modelo internacionalprofesional, de investigacion y formacion para la optimizacion prosocial de los territorios y organizaciones. La Prosocialidad transferida a la practica social en lipa ha generado intervenciones innovadoras que desde una apuesta por la transferencia del conocimiento, ha beneficiado de modo efectivo a personas y organizaciones, potenciando su creatividad, identidad y autonomia. Se sistematizan los resultados de intervencion profesional de proyectos sociales de lipa, para determinar cuales son indicadores de…
Conduit dynamics and post explosion degassing on Stromboli: A combined UV camera and numerical modeling treatment
2016
Recent gas flux measurements have shown that Strombolian explosions are often followed by periods of elevated flux, or “gas codas,” with durations of order a minute. Here we present UV camera data from 200 events recorded at Stromboli volcano to constrain the nature of these codas for the first time, providing estimates for combined explosion plus coda SO2 masses of ≈18–225 kg. Numerical simulations of gas slug ascent show that substantial proportions of the initial gas mass can be distributed into a train of “daughter bubbles” released from the base of the slug, which we suggest, generate the codas, on bursting at the surface. This process could also cause transitioning of slugs into cap b…
Mètode multinivell per promoure la prosocialitat a l’escola: contribució a la formació en RSU
2019
espanolLa prosocialidad se refiere a las acciones socialmente beneficiosas, implicando conducta, emociones y razonamiento, y aqui se propone un metodo para llevar a cabo una intervencion en centros educativos para su promocion mediante una estrategia multinivel o cadena de favores. Antecedentes: aunque no existe un antecedente especifico del metodo propuesto, existen estudios acerca de la promocion de la prosocialidad en la escuela, centrados en la conducta, las emociones o los razonamientos, y el principal antecedente es el metodo de intervencion prosocial de Robert Roche (Escotorin y Roche, 2011; Roche, 1999, 1997; Romersi, Martinez-Fernandez y Roche, 2011), de la Universidad Autonoma de …
(Ré)concilier éclairage urbain et environnement nocturne : les enjeux d’une controverse sociotechnique
2014
International audience; Our paper explains the birth of an environmental problem, i.e. light pollution, viewed as a socio-technical controversy. Supported by the actor-network approach, it traces over forty years the conditions of its emergence, transformation and dissemination to local, national and transnational levels and through various professional disciplines. Schematically, “environmentalists” uphold a holistic approach of “nocturnality” and define artificial light as a pollutant. Facing them, the “technicist” defends a segmented approach and defines artificial light as a nuisance. The introduction of this controversy into the political agenda leads to institutional decisions that gr…
