Xeric grasslands of the inner-alpine dry valleys of Austria - new insights into syntaxonomy, diversity and ecology
2021
We are grateful to the IAVS for financial support for some of the participants. We would like to give special thanks to Dr. Ernst Partl, director of the Naturpark Kaunergrat for authorizing sampling in the protected areas and for helping with the organization of the field workshop.
The identification of social economy companies in Spain. Legal problems
2018
La Ley de Economía Social 5/2001 nace con el objetivo de configurar un marco jurídico que de visibilidad a la economía social y le otorgue mayor seguridad jurídica; y con esta finalidad define la economía social y establece los requisitos que deben cumplir las entidades denominadas de economía social. Esos requisitos hacen referencia a la condición de entidad privada, al desarrollo de una actividad económica con criterios empresariales y al cumplimiento de ciertos fines y principios. Las entidades de la economía social deben perseguir el interés general, de forma directa o en conjunción con los intereses de sus miembros usuarios, y deben actuar conforme con ciertos principios que pueden cal…
An Augmented Static Olley-Pakes Productivity Decomposition with Entry and Exit Measurement and Interpretation
2015
We develop an augmented Olley–Pakes (OP) decomposition that allows us to examine how entering and exiting firms contribute to the popular OP covariance measure of allocative efficiency. Applying the decomposition to a comprehensive micro-level data, we find that a large part of the OP covariance component can be attributed to entrants and exiting firms. We also build a model of firm dynamics that is consistent with our main empirical results. In the model economy, the standard OP covariance component tends to increase with certain type of distortions because of endogenous changes in firm entry and exit.
Risk assessment and profit sharing in business networks
2011
Abstract Nowadays network is the preferred governance form to conduct economic transactions. Network solution allows to reach flexibility maintaining cost and quality level. Since network concept refers to a great variety of organizational hybrids it is possible to choose the one that fits better market requirements. The new trends in inter-organization relationships push towards network solutions: companies are interested in relationships with partners and customers to overcome resource dependence, to enter too risky market or simply differentiate their business portfolio. The proposed research focuses on the network concept aiming at highlighting threats and opportunities to investigate t…
Indicadores de responsabilidad tributaria en las fundaciones acogidas a la Ley 49/2002. Especial referencia a las fundaciones de competencia estatal
2017
En este presente trabajo se formulan indicadores de responsabilidad tributaria de las fundaciones como mecanismo de prevención de las contingencias fiscales que pudieran recaer tanto sobre estas entidades como sobre sus patronos y mecenas. Se completa así la literatura existente centrada en los ámbitos de gestión y financiero. Paralelamente, una actuación transparente de las fundaciones exige que el grado de cumplimiento de estos indicadores, sea visible por los terceros en general y por los donantes o mecenas en particular, debiéndose dar razón de dicho cumplimiento atendiendo a los distintos destinatarios de la información a suministrar. A tal fin, y siguiendo la metodología utilizada por…
Application of 5E model for learning Mechanics through inquiry in secondary education
2018
En este trabajo se examina el proceso de resolución de una actividad de indagación sobre las leyes de Newton que consiste en diseñar un montaje con el cuál averiguar qué superficie es la más adecuada para arrastrar cajas de ropa en un almacén. Los participantes son 23 estudiantes de 4º de ESO. Para la toma de datos se recogen sus respuestas escritas relativas al diseño del dispositivo, a la toma de datos, interpretación de resultados y establecimiento de conclusiones. Para el análisis se examinan utilizando como herramienta el modelo de instrucción 5E. Los resultados principales apuntan a ciertas dificultades en los desempeños del alumnado relativos a la elaboración del montaje y a la expli…
Strongly-coupled PbS QD solids by doctor blading for IR photodetection
2016
Solution-processed QD solids are emerging as a novel concept for high-performance optoelectronic devices. In this work, doctor blading is proposed for the fabrication of strongly-coupled QD solids from a PbS nanoink for photodetection at telecom wavelengths. The key step of this procedure is the solid-state ligand exchange, which reduces the interparticle distance and increases the carrier mobility in the resulting strongly-coupled QD solid. This is accomplished by replacing the original long oleylamine molecules by shorter molecules like 3-mercaptopropionic acid, as confirmed by FTIR, TGA and XPS. Further, a detailed investigation with XPS confirms the air-stability of the QD solids and th…
Electric control of the spin Hall effect by intervalley transitions
2013
Controlling spin-related material properties by electronic means is a key step towards future spintronic technologies. The spin Hall effect (SHE) has become increasingly important for generating, detecting and using spin currents, but its strength-quantified in terms of the SHE angle-is ultimately fixed by the magnitude of the spin-orbit coupling (SOC) present for any given material system. However, if the electrons generating the SHE can be controlled by populating different areas (valleys) of the electronic structure with different SOC characteristic the SHE angle can be tuned directly within a single sample. Here we report the manipulation of the SHE in bulk GaAs at room temperature by m…
Characterization of glycoconjugate expression during development of Meckel's cartilage in the rat
1995
The staining patterns of 24 biotinylated lectins were analyzed in serial sections of the mandible of 13- to 21-day-old rat embryos by means of the avidin-biotin-peroxidase method. A ubiquitous distribution of binding sites was demonstrated after incubation with Con A (Canavalia ensiformis), DSL (Datura stramonium; except bone matrix), and WGA (Triticum vulgare). ECL (Erythrina cristagalli), GSL I (Griffonia simplicifolia), SJA (Saphora japonica), VVL (Vicia villosa), DBA (Dolichus biflorus), UEA I (Ulex europeus), and LTA (Lotus tetragonobolus) were constantly negative. In early stages of development, GSL II (Griffonia simplicifolia II) was a selective marker of prechondral blastema. In con…
Derivatives of Erythropoietin That Are Tissue Protective But Not Erythropoietic
2004
Erythropoietin (EPO) is both hematopoietic and tissue protective, putatively through interaction with different receptors. We generated receptor subtype–selective ligands allowing the separation of EPO's bioactivities at the cellular level and in animals. Carbamylated EPO (CEPO) or certain EPO mutants did not bind to the classical EPO receptor (EPOR) and did not show any hematopoietic activity in human cell signaling assays or upon chronic dosing in different animal species. Nevertheless, CEPO and various nonhematopoietic mutants were cytoprotective in vitro and conferred neuroprotection against stroke, spinal cord compression, diabetic neuropathy, and experimental autoimmune encephalomyeli…
