La relación entre abuelos y nietos. Factores que predicen la calidad de la relación intergeneracional
2004
This study tries to identify the main factors determining the quality in grandparent/ grandchild relationships from the perspective of grandchildren. Three hundred and sixty one Spanish young adults responded to questions concerning the quality of their relationship with the "preferred" or "most close" grandparent. Results indicated the following aspects as significant predictors of grandparent-grandchild relationship: a) the frequency of contact between grandparents-grandchildren; b) the quality of the parent-grandparent relationship; c) the number of shared activities; and d) the perception of the grandparent as "caregiver" and "teacher".<br><br>El presente estudio se centra e…
Challenges in the use of Near Infrared Spectroscopy for improving wood quality: A review
2018
Aims of study: Forestry-related companies require quality monitoring methods capable to pass a large number of samples. This review paper is dealing with the utilization of near infrared (NIR) technique for wood analysis.Area of study: We have a global point of view for NIR applications and characterization of different kind of wood species is considered.Material and methods: NIR spectroscopy is a fast, non-destructive technique, applicable to any biological material, demanding little or no sample preparation. NIR spectroscopy and multivariate analysis serve well in laboratories where the conditions are controlled. The main challenges to NIR spectroscopy technique in field conditions are mo…
Dating of Archaeological Gold by Means of Solid State Electrochemistry
2018
[EN] In archaeology and history of art, age determination is a fundamental analytical problem. While several techniques for age determination of various materials, like radiocarbon dating, are established, these methods cannot be applied for metals, for which new techniques have to be developed. For the first time a dating method for archaeological gold objects is described which is based on a corrosion clock and electrochemical measurements, using the voltammetry of immobilized particles. Samples are prepared by one touch' with a graphite pencil, only transferring a few nanograms of the archaeological gold. The method has been calibrated with the help of a series of well-documented gold sp…
Urban Space and Gender Performativity in Knut Hamsun’s Hunger and Cora Sandel’s Alberta and Freedom
2018
In this article, I discuss the combination of city life and gender performativity in two Norwegian classics, Knut Hamsun’s Hunger (2016) [Sult, 1890] and Cora Sandel’s Alberta and Freedom (1984) [Alberte og friheten, 1931]. These are modernist novels depicting lonely human subjects in an urban space, the first one featuring a man in Kristiania (now Oslo) in the 1880s, the second one a woman and her female acquaintances in Paris in the 1920s. I interpret and compare the two novels by focusing on their intertwined construction of gender performativity and urban space. Gender norms of the city life are critical premises for how the subjects manage to negotiate with different options and obstac…
Culture and odor categorization : agreement between cultures depends upon the odors
2003
This study evaluated the effect of culture on the relationship between psychological dimensions underlying odor perception and odor categorization. In a first experiment, French, Vietnamese and American participants rated several perceptual dimensions of everyday odorants, and sorted these odorants on the basis of their similarity. Results showed that the three groups of participants differed in their perceptual judgments but agreed in categorizing the odors into four consensual groups (floral, sweet, bad, and nature). Three dimensions––pleasantness, edibility, cosmetic acceptability––discriminated these groups in the same way in the three countries. In a second experiment, the participants…
Dating archaeological strata in the Magna Mater temple using solid-state voltammetric analysis of leaded bronze coins
2017
[EN] The application of solid state electrochemistry techniques for dating archaeological strata using lead-containing bronze coins is described. The proposed methodology was applied to samples coming from the Roman archaeological site of Magna Mater Temple (Rome, Italy) occurring in different strata dating back between the second half and the end of the 4(th) century A.D. and the 20(th) century. The voltammetric signatures of copper and lead corrosion products in contact with aqueous acetate buffer, as well as the catalytic effects produced on the hydrogen evolution reaction, were used for establishing the age of different strata and dating coins belonging to unknown age. Voltammetric data…
Blodets lokkende sange. Ida Jacksons Morfar, Hitler og jeg og perpetrator postmemory
2021
Sammendrag Ida Jacksons essay Morfar, Hitler og jeg (2014) indledes med hendes opdagelse af morfarens medskyldighed i nazistiske krigsforbrydelser under 2. verdenskrig. Opdagelsen sætter scenen for Jacksons undersøgelse af morfarens livshistorie under krigen, som har været holdt skjult i familien, og for hendes udforskning af disse begivenheders betydning for hendes eget liv. Morfaren blev traumatiseret af krigen, og Jacksons essay udforsker konsekvenserne af, at morfarens traume er blevet givet videre i flere generationer. Konsekvenserne viser sig i det problematiske i at erindre, men også som en generationel skyld over morfarens handling. Denne skyld er fortsat til stede hos børn og børne…
Zein as biodegradable material for effective delivery of alkaline phosphatase and substrates in biokits and biosensors
2016
A biodegradable material, zein, is proposed as a reagent delivery platform for biokits and biosensors based on alkaline phosphatase (ALP) activity/inhibition in the presence of phosphatase substrates. The immobilization and release of both the substrate and/or the active ALP, in a biodegradable and low-cost material such as zein, a prolamin from maize, and in combination with glycerol as plasticizer have been investigated. Three zein-based devices are proposed for several applications: (1) inorganic phosphorus estimation in water of different sources (river, lake, coastal water and tap water) with a detection limit of 0.2mg/L - compared to at least 1mg/L required by legislation, (2) estimat…
Wine Quality Perception: A Sensory Point of View
2016
Wine is a complex product, which had moved from a nutritional food to a hedonic beverage in consumer representation. This fact has increased the demand of quality products in the market. In this context, it is of high interest for wine producers to understand the underlying indicators of consumers’ quality perception as well as the relative importance they attach to these cues when inferring quality in wine to reach the alignment of consumers’ expectations, needs and wants. This chapter is aimed at giving an overview of the current state of knowledge of the indicators of wine quality perception from a sensory point of view. For this purpose, the factors driving perceived quality of wine as …
