La Residencia de Estudiantes, grupos universitario y de señoritas : Madrid, 1910-1936.

Ocuparse de la Residencia de Estudiantes, teniendo en cuenta sus grupos universitario y de señoritas, un ensayo de poner en pie una institución donde se exprese esa idea de universidad en la que las dimensiones intelectuales y culturales se unen a los modos de convivir y relacionarse para lograr un nuevo entendimiento del hombre y una nueva realidad nacional. A lo largo de este estudio la configuración, el desarrollo y las realizaciones de las secciones residenciales universitaria y de señoritas se enmarcan en las dos referencias que les dan sentido: la Institución Libre de Enseñanza y la Junta para Ampliación de Estudios e Investigaciones Científicas, su organismo tutelar. Se presta especial atención a la singular forma de vida que la Residencia de Estudiantes, en coordenadas éticas y estéticas bien definidas, propone para las escogidas minorías a las que acoge y se intenta definir el modelo de hombre y mujer que tal entidad impulsa. La tesis esta dividida en capítulos sobre marco y fundamentos de la Residencia de Estudiantes, sus comienzos (1910-1915), desarrollo (1915-1936), los residentes y el funcionamiento interno del grupo universitario, actividades docentes y culturales, otras iniciativas y realizaciones del grupo universitario. La Residencia de Estudiantes plasma ejemplarmente el ideario de cuño institucionalista que había inspirado a aquella. Constituye en primer lugar una institución educativa singular. Se propone abarcar la vida entera de los estudiantes, proporcionarles una formación integral, una educación general, que atendiese al desarrollo intelectual, moral, físico y social. La Residencia rechaza las costumbres disciplinarias al uso, se rige por unas pautas flexibles, modeladas por el propio grupo. Prefigura así, la Residencia de Estudiantes, un tipo bien definido de universidad, de régimen colegial y corporativo de organización tutorial, de modo anglosajón. La Institución Libre de Enseñanza se propone formar minorías directoras.

A quantum molecular similarity analysis of changes in molecular electron density caused by basis set flotation and electric field application

Quantum molecular similarity (QMS) techniques are used to assess the response of the electron density of various small molecules to application of a static, uniform electric field. Likewise, QMS is used to analyze the changes in electron density generated by the process of floating a basis set. The results obtained show an interrelation between the floating process, the optimum geometry, and the presence of an external field. Cases involving the Le Chatelier principle are discussed, and an insight on the changes of bond critical point properties, self-similarity values and density differences is performed

Destabilizing Mutations Alter the Hydrogen Exchange Mechanism in Ribonuclease A

The effect of strongly destabilizing mutations, I106A and V108G of Ribonuclease A (RNase A), on its structure and stability has been determined by NMR. The solution structures of these variants are essentially equivalent to RNase A. The exchange rates of the most protected amide protons in RNase A (35ºC), the I106A variant (35ºC), and the V108G variant (10ºC) yield stability values of 9.9, 6.0, and 6.8 kcal/mol, respectively, when analyzed assuming an EX2 exchange mechanism. Thus, the destabilization induced by these mutations is propagated throughout the protein. Simulation of RNase A hydrogen exchange indicates that the most protected protons in RNase A and the V108G variant exchange via the EX2 regime, whereas those of I106A exchange through a mixed EX1 1 EX2 process. It is striking that a single point mutation can alter the overall exchange mechanism. Thus, destabilizing mutations joins high temperatures, high pH and the presence of denaturating agents as a factor that induces EX1 exchange in proteins. The calculations also indicate a shift from the EX2 to the EX1 mechanism for less protected groups within the same protein. This should be borne in mind when interpreting exchange data as a measure of local stability in less protected regions

Distinct Unfolding and Refolding Pathways of Ribonuclease A Revealed by Heating and Cooling Temperature Jumps

Heating and cooling temperature jumps (T-jumps) were performed using a newly developed technique to trigger unfolding and refolding of wild-type ribonuclease A and a tryptophan-containing variant (Y115W). From the linear Arrhenius plots of the microscopic folding and unfolding rate constants, activation enthalpy (ΔH#), and activation entropy (ΔS#) were determined to characterize the kinetic transition states (TS) for the unfolding and refolding reactions. The single TS of the wild-type protein was split into three for the Y115W variant. Two of these transition states, TS1 and TS2, characterize a slow kinetic phase, and one, TS3, a fast phase. Heating T-jumps induced protein unfolding via TS2 and TS3; cooling T-jumps induced refolding via TS1 and TS3. The observed speed of the fast phase increased at lower temperature, due to a strongly negative ΔH# of the folding-rate constant. The results are consistent with a path-dependent protein folding/unfolding mechanism. TS1 and TS2 are likely to reflect X-Pro114 isomerization in the folded and unfolded protein, respectively, and TS3 the local conformational change of the β-hairpin comprising Trp115. A very fast protein folding/unfolding phase appears to precede both processes. The path dependence of the observed kinetics is suggestive of a rugged energy protein folding funne

Internal structure of chlorosomes from brown-colored Chlorobium species and the role of carotenoids in their assembly

Chlorosomes are the main light harvesting complexes of green photosynthetic bacteria. Recently, a lamellar model was proposed for the arrangement of pigment aggregates in Chlorobium tepidum chlorosomes, which contain bacteriochlorophyll (BChl) c as the main pigment. Here we demonstrate that the lamellar organization is also found in chlorosomes from two brown-colored species (Chl. phaeovibrioides and Chl. phaeobacteroides) containing BChl e as the main pigment. This suggests that the lamellar model is universal among green sulfur bacteria. In contrast to green-colored Chl. tepidum, chlorosomes from the brown-colored species often contain domains of lamellar aggregates that may help them to survive in extremely low light conditions. We suggest that carotenoids are localized between the lamellar planes and drive lamellar assembly by augmenting hydrophobic interactions. A model for chlorosome assembly, which accounts for the role of carotenoids and secondary BChl homologs, is presented

Pressure-jump-induced kinetics reveals a hydration dependent folding/unfolding mechanism of ribonuclease A

Pressure-jump (p-jump)-induced relaxation kinetics was used to explore the energy landscape of protein folding/unfolding of Y115W, a fluorescent variant of ribonuclease A. Pressure-jumps of 40MPa amplitude (5ms dead-time) were conducted both to higher (unfolding) and to lower (folding) pressure, in the range from 100 to 500MPa, between 30 and 50°C. Significant deviations from the expected symmetrical protein relaxation kinetics were observed. Whereas downward p-jumps resulted always in single exponential kinetics, the kinetics induced by upward p-jumps were biphasic in the low pressure range and monophasic at higher pressures. The relative amplitude of the slow phase decreased as a function of both pressure and temperature. At 50°C, only the fast phase remained. These results can be interpreted within the framework of a two-dimensional energy surface containing a pressure- and temperature-dependent barrier between two unfolded states differing in the isomeric state of the Asn-113–Pro-114 bond. Analysis of the activation volume of the fast kinetic phase revealed a temperature-dependent shift of the unfolding transition state to a larger volume. The observed compensation of this effect by glycerol offers an explanation for its protein stabilizing effect

Cultura organizacional : influência na produtividade : análise de um caso

As últimas três décadas têm sido pautadas por significativas mudanças de métodos de trabalho nas organizações, em resultado da globalização dos mercados, da tecnologia e consequentes pressões competitivas , o que obriga as organizações a serem eficientes e a colocar na linha da frente das preocupações a mudança das estratégias de gestão. Se, por um lado, a maioria das organizações concentra-se na qualidade, na satisfação dos clientes , no cumprimento de prazos de entrega, na inovação e na diversificação dos produtos, por outro, sentem a necessidade de integrar factores subjectivos e simbólicos que enfatizem , quer as semelhanças no seu interior quer as diferenças em relação às demais organizações. Com a perspectiva do aumento da eficiência, as organizações não podem limitar as suas preocupações aos aspectos técnicos e operacionais , necessitam de dar mais atenção ao capital imanente das suas forças de trabalho e ao seu ambiente cultural. Embora seja uma tarefa difIcil, o presente trabalho tem como objectivo avaliar a influência da cultura organizacional na produtividade. De forma a atender à complexidade das duas variáveis, produtividade e cultura organizacional, a medição dos índices de produtividade da mão-de-obra e a análise dos elementos culturais pode não ser o caminho mais representativo para evidenciar a verdadeira contribuição da cultura organizacional ao nível de produtividade dos trabalhadores . Porém , este estudo pode dar início a um novo trabalho de investigação junto dos profissionais que queiram aprofundar melhor os resultados e as conclusões obtidas.

Essais de terminologie de la nouvelle muséologie sociale, libérons le concept

ous présenterons en premier lieu la nomenclature du processus expositionnel, puis, en second lieu, une sélection de termes de la muséologie propre ou de termes associés qualifiant la muséologie sociale. Certains parleront de détournement. Nous préférons mettre au compte de l’enrichissement de l’expérience muséologique une terminologie qui puisse faire corps avec celle-ci, exprimant sa formulation comme son esprit. Il est à souhaiter que l’ensemble de la muséologie en tienne compte, favorisant les passages entre les orientations idéologiques.
