De l'antropologia a l'educació. Una lectura des de Margaret Mead

En el presente artículo se ensaya una aproximación a la obra de la antropóloga Margaret Mead en clave pedagógica. Siendo así que se muestra una interpretación sobre sus pensamientos alrededor de la educación a partir de los estudios, comentarios y opiniones sobre los sistemas educativos, relaciones educativas y procesos de enseñanza aprendizaje que se explicitan, reiteradamente, a lo largo de su obra. A fin de cuentas, y como la propia autora indicaba, estudiar la educación era implícitamente necesario a todo estudio antropológico. Concepción que la llevó a incluir en la mayor parte de sus estudios, variables de análisis educativos, llegando incluso a centralizar la atención en este ámbito como idea central de algunos de sus escritos. Añadir además que, en esta síntesis se ha optado por presentar la evolución de su pensamiento pedagógico en base a momentos singulares y carismáticos, mostrando así las distintas continuidades y discontinuidades de su pensamiento.

Gone with the Wind and the Southern Way of Life: the Civil War as described in Margaret Mitchell’s Novel

This essay examines the American Civil War of 1861 – 1865, which is also known as the bloodiest war that the United States has ever experienced. The pretext for the war was the abolition of slavery in the South, and after many battles the Southern states lost: as a consequence, they experienced major changes in their economic and social life. This interesting piece from American history can be traced out throughout the characters’ lives in the novel Gone with the Wind which has been thoroughly analyzed in order to draw nearer and to comprehend the changes in the Southern way of life before and after the war. The author, Margaret Mitchell, was born in Atlanta, Georgia, and grew up with the stories about the war. As a result, Gone with the Wind studies not only its causes, but also the years after its end – a period which is not generally a subject of history and receives little attention – and the effects that such reversals have on former planters and slaves. From the position of contemporaneity, the reader can see that such changes in a society do not end with the laying down of an act, or in this case the end of the war, but they continue during many years; thus, the modern world can draw conclusions and lessons for events that are happening at the moment.

The ‘Dys-Appearing’ Body in Doris Lessing’s The Diary of a Good Neighbour and Margaret Forster’s Have the Men Had Enough?

If the old body is usually read as a synonym of fragility and upcoming illness, even though not the case for most elderly citizens, the reality is that the longer we live, the increased probability of being affected by different illnesses cannot be eluded or denied. In Doris Lessing’s The Diary of a Good Neighbour and Margaret Forster’s Have the Men Had Enough? the reader is invited to participate in the day-to-day routines of two aged female protagonists, as well as to empathize with their inner feelings as they go through their last life stage. In fact, their ‘dys-appearing’ bodies, marked by their respective terminal illnesses, force these characters to grow closer to those around them and to accept the help of their families and friends, despite their desire to keep their free will and independence until the very end. The analysis of the two novels within the framework of ageing studies aims to show the contradictions existing between a growing ageing society and the negative cultural connotations of old age in Western society and the need to revise them.

Temporal changes in the expression and distribution of adhesion molecules during liver development and regeneration

We have compared by immunocytochemistry and immunoblotting the expression and distribution of adhesion molecules participating in cell-matrix and cell-cell interactions during embryonic development and regeneration of rat liver. Fibronectin and the fibronectin receptor, integrin alpha 5 beta 1, were distributed pericellularly and expressed at a steady level during development from the 16th day of gestation and in neonate and adult liver. AGp110, a nonintegrin fibronectin receptor was first detected on the 17th day of gestation in a similar, nonpolarized distribution on parenchymal cell surfaces. At that stage of development haemopoiesis is at a peak in rat liver and fibronectin and receptors alpha 5 beta 1 and AGp110 were prominent on the surface of blood cell precursors. During the last 2 d of gestation (20th and 21st day) hepatocytes assembled around lumina. AGp110 was initially depolarized on the surface of these acinar cells but then confined to the lumen and to newly-formed bile canaliculi. At birth, a marked increase occurred in the canalicular expression of AGp110 and in the branching of the canalicular network. Simultaneously, there was enhanced expression of ZO-1, a protein component of tight junctions. On the second day postpartum, presence of AGp110 and of protein constituents of desmosomes and intermediate junctions, DGI and E-cadherin, respectively, was notably enhanced in cellular fractions insoluble in nonionic detergents, presumably signifying linkage of AGp110 with the cytoskeleton and assembly of desmosomal and intermediate junctions. During liver regeneration after partial hepatectomy, AGp110 remained confined to apical surfaces, indicating a preservation of basic polarity in parenchymal cells. A decrease in the extent and continuity of the canalicular network occurred in proliferating parenchyma, starting 24 h after resection in areas close to the terminal afferent blood supply of portal veins and spreading to the rest of the liver within the next 24 h. Distinct acinar structures, similar to the ones in prenatal liver, appeared at 72 h after hepatectomy. Restoration of the normal branching of the biliary tree commenced at 72 h. At 7 d postoperatively acinar formation declined and one-cell-thick hepatic plates, as in normal liver, were observed.

Nutritional and insulin regulation of fatty acid synthetase and leptin gene expression through ADD1/SREBP1.

The ability to regulate specific genes of energy metabolism in response to fasting and feeding is an important adaptation allowing survival of intermittent food supplies. However, little is known about transcription factors involved in such responses in higher organisms. We show here that gene expression in adipose tissue for adipocyte determination differentiation dependent factor (ADD) 1/sterol regulatory element binding protein (SREBP) 1, a basic-helix-loop-helix protein that has a dual DNA-binding specificity, is reduced dramatically upon fasting and elevated upon refeeding; this parallels closely the regulation of two adipose cell genes that are crucial in energy homeostasis, fatty acid synthetase (FAS) and leptin. This elevation of ADD1/SREBP1, leptin, and FAS that is induced by feeding in vivo is mimicked by exposure of cultured adipocytes to insulin, the classic hormone of the fed state. We also show that the promoters for both leptin and FAS are transactivated by ADD1/SREBP1. A mutation in the basic domain of ADD1/SREBP1 that allows E-box binding but destroys sterol regulatory element-1 binding prevents leptin gene transactivation but has no effect on the increase in FAS promoter function. Molecular dissection of the FAS promoter shows that most if not all of this action of ADD1/SREBP1 is through an E-box motif at -64 to -59, contained with a sequence identified previously as the major insulin response element of this gene. These results indicate that ADD1/SREBP1 is a key transcription factor linking changes in nutritional status and insulin levels to the expression of certain genes that regulate systemic energy metabolism.

Holographic phase transitions with fundamental matter

The holographic dual of a finite-temperature gauge theory with a small number of flavors typically contains D-brane probes in a black hole background. At low temperature, the branes sit outside the black hole and the meson spectrum is discrete and possesses a mass gap. As the temperature increases, the branes approach a critical solution. Eventually, they fall into the horizon and a phase transition occurs. In the new phase, the meson spectrum is continuous and gapless. At large Nc and large't Hooft coupling, we show that this phase transition is always first order. In confining theories with heavy quarks, it occurs above the deconfinement transition for the glue.

La forma lògica de les oracions d'acció i la tesi d'Anscombe

This paper has three sections. In the first one, I expose and discuss Davidson's semantic account of adverbial sentences: the basic idea is that these sentences involve quantification over events, and I defend that view from opposing perspectives like the theory of adverbs as predicate modifiers. In the second section I defend the claim that in english constructions following the scheme: ¿X did V by T-ings¿, we are referring to the same action of X; what is sometimes called ¿The Anscombe Thesis¿. Again I discuss competing theories only to conclude that the Anscombe Thesis is true. In the third section, however, it is shown that to assume as premisses these two theses -Davidson's account and the Anscombe Thesis- leads to a serious conflict. Alternative solutions are worked out and rejected. It is also argued that the only tenable solution depends on certain metaphysical assumptions. Finally, however, I will cast doubt on this solution.

Ras-association domain of sorting nexin 27 is critical for regulating expression of GIRK potassium channels

G protein-gated inwardly rectifying potassium (GIRK) channels play an important role in regulating neuronal excitability. Sorting nexin 27b (SNX27b), which reduces surface expression of GIRK channels through a PDZ domain interaction, contains a putative Ras-association (RA) domain with unknown function. Deleting the RA domain in SNX27b (SNX27b-DRA) prevents the down-regulation of GIRK2c/GIRK3 channels. Similarly, a point mutation (K305A) in the RA domain disrupts regulation of GIRK2c/GIRK3 channels and reduces H-Ras binding in vitro. Finally, the dominant-negative H-Ras (S17N) occludes the SNX27b-dependent decrease in surface expression of GIRK2c/GIRK3 channels. Thus, the presence of a functional RA domain and the interaction with Ras-like G proteins comprise a novel mechanism for modulating SNX27b control of GIRK channel surface expression and cellular excitability.

Relación triangular en danza movimiento terapia: "cuando el instante no es efímero"

Esta tesina pretende investigar si el concepto de relación triangular existe y es apto para el campo de la Danza Movimiento Terapia. Para lograr esto nos basaremos en una correlación teórica con el campo de la arte terapia, donde la relación triangular se utiliza como herramienta de trabajo terapéutico. Nuestro fin es encontrar resultados teórico/prácticos, que permitan visualizar su existencia y nos muestren lo que sucede en la relación terapéutica, cuando dicho término se consolida. En este camino, la materialización de la danza/movimiento, como tercer elemento de la relación triangular, será un punto clave e interesante, que nos mostrará nuevos caminos psicoterapéuticos.

Antropologia dels sentits.Selecció bibliogràfica

Si algú volgués revisar I'estat contemporani de l'antropologia dels sentits hauria de començar amb el llibre font editat per David Howes i titulat The Vorieties of Sensory Experience (Howes ed. 199 1), parant una atenció especial a l'assaig introductori de Howes i a la conclusió de Howes i Classen que ofereix un paradigma per estudiar el sensorium (un terme derivat de la primera secció de The Presence of the Word de Walter Ong (1671 que també estd reeditada al volum de Howes). Howes i els seus companys també ofereixen un recompte d'última hora de la seva posició i recerca actual a la pàgina web de la Universitat Concordia (Canada). D'altres qüestions generals recents inclouen Landscopes of the Mind (1990) de Porteous i Worlds of Sense (1993) de Classen, per a els lectors potser volen tornar a la qüesti6 de Whorf a Language, Thought ond Reolity dels diversos móns conceptuals dels hopis i la 'Mitjana europea estdndard' tal i com s'expressa a través del llenguatge (Whorf 1956).
