Marx y Engels y la división sexual del trabajo en la familia: ambigüedades, equívocos y vacíos teóricos
2018
Dada la importante influencia de Marx y Engels en el análisis de la estructura social, no sorprende el notable impacto de su obra en el estudio del papel de la mujer en la familia. Sin embargo, su herencia en este ámbito sociológico ha dado lugar a interpretaciones muy polarizadas. Este artículo quiere aportar algo de luz evidenciando las contradicciones del marxismo al estudiar el papel de la mujer en la familia. Para ello se comparan las contribuciones de Marx y Engels para calibrar posibles diferencias en las posturas de dos autores que en otros ámbitos han presentado un pensamiento muy homogéneo. Los resultados obtenidos permiten afirmar que, a pesar de su innegable influencia en el pen…

The "Film and Creative Engagement Project" : Audiovisual Accessibility and Telecollaboration
2020
ABSTRACT: Globalisation and the advancement of ICTs invite the development of learners’ strategies and communication skills in higher education to participate fully in digitally networked societies. This paper analyses the results of a pilot study which is part of Film and Creative Engagement (FaCE), a collaborative research project between Manchester Metropolitan University (MMU), UK, and Instituto Tecnológico de Estudios Superiores de Monterrey (ITESM), Campus Laguna in Torreón, Mexico. There were two main aims: (1) to create a short project that was inspiring, stimulating and enjoyable that could be transferable to other high education institutions; and (2) to provide a training that cou…
FISCAL POLICY`S INFLUENCE ON ECONOMIC GROWTH IN THE EUROPEAN UNION
2012
In this paper we study the impact of the fiscal policy on the economic growth for European Union, for the period 2000-2009. This subject represents a very debated problem in the economic literature. Our findings shows that, from the analysis of correlation between economic growth rate and total rate of taxation, there is generally an inverse relationship, meaning that an increase in the tax rate adversely affects economic growth. Continuing the analysis of the correlation between economic growth rate and total tax rate components it can be seen that there is an inverse relationship between labor taxation and capital taxation and economic growth in EU Member States. Both labour and capital t…
Vertical distribution of two sympatric labrid fishes in the Western Mediterranean and Eastern Atlantic rocky subtidal: local shore topography does ma…
2011
Changes in the shore topography (e.g. slope) occur at a scale of hundreds of meters in several locations in the Lusitanian and the Mediterranean Sea provinces. We tested whether differences in the bottom inclination might affect the vertical distribution patterns of two sympatric coastal labrid fishes, the rainbow wrasse Coris julis and the ornate wrasse Thalassoma pavo. Visual censuses were used to determine the distribution and abundance of these labrid species in high (‡30 ) and low (£3 ) slope rocky substrates covered by brown macroalgae and at two different depths (shallow, 4–7 m, and deep 14–20 m). Pectoral fin aspect ratio was used as an estimate of swimming performance to potentiall…
Tyytyväisyys työaikapankkiin
2009
Tutkimuksessa tarkasteltiin työaikapankkiin tyytyväisyyttä ennustavia tekijöitä. Tutkimus perustuu yhdeksässä työorganisaatiossa tehdyn kyselyn aineistoon (N = 268). Analyysit suoritettiin polkuanalyysina, jolloin selittäjien kausaalinen järjestys ja keskinäinen riippuvuus pystyttiin ottamaan huomioon. Selvä enemmistö vastaajista oli tyytyväisiä työaikapankkiin. Tyytyväisyyttä lisäsivät mahdollisuus kokonaisen vapaa-päivän viettämiseen säästetyistä tunneista, korkea asema organisaatiossa sekä työntekijöiden organisaation johdolta saama tuki. Tyytyväisyyttä heikensivät ongelmat säästettyjen vapaiden käytössä sekä työaikatilin saldorajojen huono mitoitus suhteessa työtehtävien vaativuuteen. K…
Hong Kong Palermo Fluid Cities
2017
L'articolo affronta il concetto di "fluidità" a partire dall'esperienza dell'International Workshop on Urbanism and Design che si è svolto da gennaio a marzo 2017 a Palermo: circa 80 studenti hanno sperimentato una metodologia di lavoro di collaborative urbanism and design sotto la responsabilità scientifica di Maurizio Carta e Dario Russo (Università di Palermo) e di Manuela Catania e Ero Pagla (Raffles Design Institute di Hong Kong).
Liposomes modified by mono- and bis-phthalocyanines: A comprehensive EPR study.
2016
The impact of selected metallophthalocyanines, featuring diverse molecular structure, upon the fluidity of liposome membranes was studied using the spin label EPR technique. The “mono”-type MPc’s (M = Zn, Sn; Pc = C32H16N8 is the phthalocyanine ligand) and sandwich LnPc2 complexes (Ln = Nd, Sm, Gd) were explored. Liposomes were obtained in a sonication process, from egg yolk lecithin (EYL) in water. TEMPO and 16-DOXYL spin labels were used to monitor the peripheral and central part of the lipid double layer, respectively, which allowed to localize the phthalocyanine additive within the bilayer, as well as to perform independent measurements of changes in fluidity upon addition thereof. All …
Addition of milk or caseinophosphopeptides to fruit beverages to improve iron bioavailability?
2010
Abstract A study has been made of the influence of caseinophosphopeptides (CPPs) added to a fruit beverage versus milk based fruit beverages upon iron retention, transport and uptake, using a combined simulated gastrointestinal digestion/Caco-2 cell system. Grape concentrate, orange concentrate, and apricot puree were used for sample formulation. Eight samples were assayed with/without added Fe sulphate (3 mg/100 ml fruit beverage) and/or added Zn sulphate (1.6 mg/100 ml fruit beverage), with/without skimmed milk (11% v/v). The addition of milk to fruit beverages exerted a positive effect on iron retention, transport and uptake versus fruit beverages, and this effect was greater than that o…
In vitrobioaccessibility of iron and zinc in fortified fruit beverages
2009
Summary Iron and zinc bioaccessibility was estimated in the in vitro gastrointestinal digests of six different fortified fruit beverages (Fb) containing iron and/or zinc and/or skimmed milk (M). Solubility values can be used to establish trends in relative bioavailability of iron and zinc, as the first stage towards mineral bioavailability comprises solubility in the intestinal tract. FbFe, FbFeM and FbFeZnM samples showed iron bioaccessibility above 88%, differing (P < 0.05) from those of FbFeZn (53%). In turn, FbZn, FbFeZn and FbZnM samples presented higher zinc bioaccessibility (above 68%), differing (P < 0.05) from those of FbFeZnM (48%). The presence of milk-derived caseinophosphopepti…
