Proximal Paradox
2000
In today's societies relationships between near relatives and friends appear to be somewhat paradoxical. Some accounts present them as the social ideal, exalting the solidarity and altruism represented by proximal relationships. By contrast, others point to the social dangers in such relationships when they are conducted in the public sphere. In order to grasp the coexistence of these opposite views, this article attempts to place proximal relationships in the explanatory context of a gift economy, a concept with a long history in anthropology and which has lately been the focus of interest of a significant group of social thinkers.
Accumulation and destruction of the trust ? : Popperian inspiration plan
2000
When, following other social sciences, economists address the mechanism of trust, they typically focus on the search of a justification or a foundation for trusting, the implicit starting point of the process they have in mind being zero trust, or distrust. By contrast, the present paper, inspired by the philosophy of Popper, suggests, as a starting point for trust, an individual decision associated with what Popper calls a conjecture - that is, a kind of theory - on how the individual (potentially) trusted "functions". The conjecture requires no justification but only the test of its implications. In turn, the decision to trust or to distrust does not reflect in a mechanical or passive way…
Obesity and Interpersonal Problems: An Analysis with the Interpersonal Circumplex
2011
This study examines the interpersonal problems profiles of obese individuals by cluster analysing the interpersonal problems circumplex scores of participants. The Inventory of Interpersonal Problems—Short Circumplex (IIP-32) was completed by 368 treatment-seeking obese individuals. These data were cluster analysed, and groups of obese subjects defined by varying interpersonal problems were compared with regard to psychological distress, self-esteem, body dissatisfaction, quality of life and binge behaviours. Cluster analyses of the IIP-32 resulted in four clusters, which occupied two quadrants of the interpersonal circumplex. Several differences in body mass index, psychological distress, …
Flow cytometric kinetic assay of the activity of Na+/H+ antiporter in mammalian cells.
2004
Background The Na+/H+ exchanger (NHE) of mammalian cells is an integral membrane protein that extrudes H+ ion in exchange for extracellular Na+ and plays a crucial role in the regulation of intracellular pH (pHi). Thus, when pHi is lowered, NHE extrudes protons at a rate depending of pHi that can be expressed as pH units/s. Methods To abolish the activity of other cellular pH-restoring systems, cells were incubated in bicarbonate-free Dulbecco's modified Eagle's medium buffered with HEPES. Flow cytometry was used to determine pHi with 2′,7′-bis-(2-carboxyethyl)-5-(and-6)-carboxyfluorescein acetoxymethyl ester or 5-(and-6)-carboxy SNARF-1 acetoxymethyl ester acetate, and the appropriate fluo…
Enseñanza de las ciencias : revista de investigación y experiencias didácticas
2021
Este trabajo se plantea estudiar el papel de la Química Verde en la educación científica para contribuir, desde ese campo, a la Ciencia de la Sostenibilidad y, por tanto, a la transición hacia sociedades sostenibles. Se mostrarán unos primeros resultados de una investigación llevada a cabo sobre la atención que la enseñanza secundaria y la propia investigación en el campo de la didáctica de las ciencias están prestando a las aportaciones de la Química Verde, y la posibilidad de su incorporación en la formación de la ciudadanía y la adopción de medidas necesarias para contribuir a la construcción de un futuro sostenible. Se pretende así responder a los numerosos llamamientos para que la educ…
Kropp i bevegelse i bildeboka : Känner du Pippi Långstrump?
2011
In Astrid Lindgren’s authorship, there are many bodies in motion, and one of her most movable and energetic characters is Pippi Longstocking. In the illustrated novels about Pippi (Lindgren and Nyman 1945, 1946, and 1948) there are relatively few pictures, and as a result, Lindgren’s words carry most of the story. In the novels, her words have a greater functional load (Kress 2003, 46 ) than Nyman’s pictures. Naturally then, the words convey most of the information about Pippi and the other characters’ movements. But how does the portrayal of bodies in motion change when Pippi is portrayed in picturebooks where the pictures have a lot more space, ie, a greater functi…
ACCULTURATION STUDIES IN SPAIN IN THE LAST DECADE
2017
In a globalized world, numerous groups of people come into permanent contact with each other and experience psychosocial changes. These changes, produced during contact between culturally different groups, are called acculturation. In the present study, a systematic review was carried out of 18 journal articles that have researched this phenomenon over the last decade (2005-2015) in Spain. The results show that the main topics studied are the areas of nuclear and peripheral acculturation, the role of prejudice in the adoption of one acculturation style or another, the influence of the acculturation strategies adopted on people’s mental health and other variables that influence the process o…
Effects of distance and scale dependence in geographical models of cities and territories
2019
International audience; This third chapter questions the essential role of distance and scale dependence in models to analyzing the spatial configuration of human settlements and activities, as well as the processes that lead to their evolution, with reference to urban or regional study areas. The subject of study therefore concerns both the form of human settlements and the actions of people (individuals, groups) in their territory (or territories). A human settlement consists of the materialization in space-the physical inscription-of one or more human activities. It is characterized by a certain degree of sustainability. It can be a group of a few buildings or a larger group of thousands…
3′-Demethyldihydromaldoxin and dihydromaldoxin, two anti-inflammtory diaryl ethers from a Steganospora species
2012
CXCL10 (IP-10) is a highly inducible chemoattractant, which contributes to the recruitment of inflammatory cells such as macrophages and T-lymphocytes and thereby has important roles in chronic inflammatory conditions. In a search for new inhibitors of CXCL10 expression in MonoMac6 (MM6) cells, the new diaryl ether 3'-demethyldihydromaldoxin (1) along with the known compound dihydromaldoxin (2), were isolated from fermentations of a Steganospora species. The structures of the compounds were elucidated by a combination of one- and two-dimensional NMR spectroscopy and mass spectrometry. Compounds (1) and (2) inhibited lipopolysaccharide (LPS)/interferon-γ (IFN-γ)-induced CXCL10 promoter activ…
Oxacyclododecindione, a Novel Inhibitor of IL-4 Signaling from Exserohilum rostratum
2008
In a screening program for new metabolites from fungi inhibiting the IL-4 mediated signal transduction, a novel chlorinated macrocyclic lactone, designated as oxacyclododecindione, was isolated from fermentations of the imperfect fungus Exserohilum rostratum. The structure was determined by a combination of spectroscopic techniques. Oxacyclododecindione inhibits the IL-4 induced expression of the reporter gene secreted alkaline phosphatase (SEAP) in transiently transfected HepG2 cells with IC50 values of 20-25 ng/ml (54-67.5 nM). Studies on the mode of action of the compound revealed that the inhibition of the IL-4 dependent signaling pathway is caused by blocking the binding of the activat…
