ANÁLISIS DE LA ESTRATEGIA DE INNOVACIÓN EN LOS KIBS: MODOS DE INNOVACIÓN PARA LOS P(professional) y los T(technological)

Berné Martínez, José Miguel 14 March 2016 (has links)
[EN] The purpose of this thesis is to analyze the innovation strategy and its impact on the "performance" of the knowledge intensive business services, or KIBS. The research is based on the data obtained from the CIS in 2006 provided by Eurostat. The aim of the survey is to quantify the innovative activities of the surveyed firms. The reference period used in the survey are data referred to 2006, the areas of activity (NACE) that have been considered as a population to study, as the sample is from 2006 are referenced to NACE-93, are those which encompass the activities of the KIBS (2174 firms): groups of economic activities: 72, 73, and 74, where T-KIBS (subsample of 1637 firms) corresponding to NACE 72 and 73 and P-KIBS (subsample of 537 firms) corresponding to NACE 74, except for 743 and 742 which are also T-KIBS. The originality of the work lies in differentiating KIBS in (professional) P-KIBS and (technological) T-KIBS. The pattern of innovation is built through the study of the absorption capacity (direct and indirect influence on external sources of knowledge), the size and technological level (separation P and T) on the results of innovation. The results highlight the different behavior in terms of innovation strategies followed by T-KIBS against the P-KIBS, an assimilation to R&D innovators and non-R&D innovators respectively. Confirming how the T-KIBS make more innovations with internal R&D, while the P-KIBS, replacing that internal R&D for the acquisition of equipment (hardware and/or software) in the innovation strategy. While T are closer to innovative R&D, P are identified more with the innovators without R&D. It also shows how the different strategies of KIBS (P and T) influence the internal and external capabilities that shape the pattern of innovation and its influence on the results and types of innovation. / [ES] El propósito de este trabajo es analizar la estrategia de innovación y su impacto en la "performance" de los knowledge intensive business services o KIBS. La investigación se realiza a partir de los datos obtenidos del CIS de 2006 proporcionados por Eurostat. El objetivo de la encuesta es cuantificar las actividades innovadoras de las empresas. El período de referencia utilizado en la encuesta, son datos referidos al año 2006, los sectores de actividad (CNAE) que se han considerado como población para el estudio, como la muestra es del año 2006 son referenciados con CNAE-93, son aquellos que engloban las actividades de los KIBS (2174 empresas): grupos de actividades económicas: 72, 73 y 74, donde T-KIBS (submuestra de 1637 empresas) son CNAE 72 y 73 y P-KIBS (submuestra de 537 empresas) CNAE 74, excepto 743 y 742 que también son T-KIBS. La originalidad del trabajo radica en segmentar los KIBS en (profesional) P-KIBS y (tecnológicos) T-KIBS. El patrón de innovación se construye a través del estudio de la capacidad de absorción (influencia directa e indirecta sobre las fuentes de conocimiento externas), el tamaño y el grado tecnológico (separación P y T) sobre los resultados de la innovación. Los resultados subrayan el comportamiento diferente en cuanto a las estrategias de innovación seguidas por los T-KIBS frente a los P-KIBS, una asimilación a los innovadores I+D y a los innovadores no I+D respectivamente. Confirman cómo los T-KIBS realizan más innovaciones con I+D interna, mientras que los P-KIBS, sustituyen dicha I+D interna por la adquisición de maquinaria (hardware y/o software) en la estrategia de innovación. Mientras que los T se asemejan más a los innovadores I+D, los P se identifican en mayor medida con los innovadores sin I+D. Se demuestra también cómo las diferentes estrategias de KIBS (P y T) influyen en las capacidades internas y externas que conforman el patrón de innovación y su influencia sobre los resultados y tipologías de innovación. / [CAT] El propòsit d'aquest treball és analitzar l'estratègia d'innovació i el seu impacte en la "performance" dels knowledge intensive business services o KIBS.

Vad betyder queer för mig? : En intervjustudie om queeridentitet

Ninni, Sundin January 2020 (has links)
Syftet med denna studie är att undersöka queeridentitet. Då identitet generellt sett avser något en individ söker sig till för känslan av samhörighet, men även förankring i sitt egna jag, så kan identitet även vara ett uttryck för foglighet till en samhällelig förväntan. Queer manifesterar sig till det motsatta – en identitet som går emot samhällets förväntan av vad en individ bör anta för typ av identitet. Valet om queeridentitet i denna studie framför en normativ identitet gör att begreppet queer åskådliggör komplexiteten om hur identitet kan ta sig i uttryck, och även hur identiteten skapar konfliktartade känslor och en inre friktion av att söka, acceptera och sedan förankra sin identitet och tillhörighet. Studien antar en kvalitativ ansats varvid fyra semistrukturerade intervjuer genomförts. Resultatet visar på att queeridentiteten är svår att definiera, även för individer som själva åberopar identiteten, men samtidigt görs tydliga anspråk på normkritik och dekonstruktion om vad identitet är och bör vara. Identiteten blir tydlig när den kontextualiseras till en omvärld, när den interagerar och handlar i ett socialt sammanhang, men svår att konkretisera när den isoleras inför individen själv.

Exploiting excited-state aromaticity for the design of efficient molecular motors : A quantum chemical study

Engberg, André January 2019 (has links)
In this work, a study of a recent approach in the design of light-driven molecular motors is presented. The approach involves enabling part of the motor to obtain aromatic-like properties through photoexcitation, and is found to significantly facilitate the rotary motion by reducing the barriers normally present in the excited-state potential energy surfaces of rotary motors.

Synthesis, characterization and catalytic application of carbonyl complexes of molybdenum and tungsten in epoxidation of some alkenes

0gweno, Aloice 0. January 2010 (has links)
>Magister Scientiae - MSc / In this thesis we describe the synthesis of several carbonyl complexes of molybdenum and tungsten, compounds (Cl-ClO). The compounds Cl- C4 are zero valent carbonyl complexes containing N-base ligands prepared by following a common synthetic procedure. Compounds Cl and C2 were metal pentacarbonyl of 3-(1-methylpyrrolidin-2-yl) pyridine while C3 and C4 are metal tetracarbonyl complexes of 3, 5- dimethylpyrazole, (M=Mo, W). The compounds C5-C10 are divalent metal carbonyl complexes. Compounds CS and C6 were 3,5-dimethylpyrazole dibromotricarbonyl metal complexes prepared from the dibromotetracarbonyl metal dimers at room temperature while the compounds C7 and C8 were cyclopentadienyl halogenoaryltricarbonyl complexes prepared from the cyclopentadienyl metal dimers. Compounds C9 and ClO were prepared from cyclopentadienyl metal dimers by reacting the [CpM(C0)3r anion with CCl4 to obtain [CpM(C0)3Cl] and further reacted with 3-(1- methylpyrrolidin-2-yl) pyridine. All the compounds, Cl-ClO, were characterized by the standard analytical techniques such as FTIR, 1H, 13C NMR; and UV-Vis spectroscopy. Compound C4 was characterized by X-ray crystallography. The structure is depicted as having a distorted octahedral geometry around the metal centre. The compounds Cl-ClO were then tested towards the epoxidation of selected cyclic and straight chain alkenes. The substrates used were cis-cyclooctene (Cyg), 1-octene (C8) cyclohexene (Cy6), 1-hexene (C6) and styrene (Sty). The epoxidation reactions were carried out at a temperature of 55 °C using tertbutylhydroperoxide (TBHP) as the oxidant and dichloroethane (DCE) as the solvent. The metal carbonyl complexes were pre-activated by first reacting them with the oxidant TBHP to obtain the metal-oxo complexes which are the active compounds for epoxidation reactions. The products were analyzed using GC techniques. The compounds, Cl-ClO showed a promising activity towards epoxidation reactions owing to the high conversions obtained by these compounds. For example, conversions of 81% (1-octene), 90% (cis-cyclooctene) were obtained by compound C5, 87% (cis-cyclooctene-compound C3, 95% (cis-cyclooctene-compound · C7) and 69% (ciscyclooctene- compound C4) for an average period of 24 h. The divalent metal carbonyl complexes showed a higher activity but with poor selectivity towards the expected epoxides compared to the zero valent metal carbonyl complexes.

Phosphorylation-Dependent Pin1 Isomerization of ATR: Its Role in Regulating ATR’s Anti-Apoptotic Function at Mitochondria, and the Implications in Cancer

Makinwa, Yetunde, Musich, Phillip R., Zou, Yue 30 April 2020 (has links)
Peptidyl-prolyl isomerization is an important post-translational modification of protein because proline is the only amino acid that can stably exist as cis and trans, while other amino acids are in the trans conformation in protein backbones. This makes prolyl isomerization a unique mechanism for cells to control many cellular processes. Isomerization is a rate-limiting process that requires a peptidyl-prolyl cis/trans isomerase (PPIase) to overcome the energy barrier between cis and trans isomeric forms. Pin1, a key PPIase in the cell, recognizes a phosphorylated Ser/Thr-Pro motif to catalyze peptidyl-prolyl isomerization in proteins. The significance of the phosphorylation-dependent Pin1 activity was recently highlighted for isomerization of ATR (ataxia telangiectasia- and Rad3-related). ATR, a PIKK protein kinase, plays a crucial role in DNA damage responses (DDR) by phosphorylating hundreds of proteins. ATR can form cis or trans isomers in the cytoplasm depending on Pin1 which isomerizes cis-ATR to trans-ATR. Trans-ATR functions primarily in the nucleus. The cis-ATR, containing an exposed BH3 domain, is anti-apoptotic at mitochondria by binding to tBid, preventing activation of pro-apoptotic Bax. Given the roles of apoptosis in many human diseases, particularly cancer, we propose that cytoplasmic cis-ATR enables cells to evade apoptosis, thus addicting cancer cells to cis-ATR formation for survival. But in normal DDR, a predominance of trans-ATR in the nucleus coordinates with a minimal level of cytoplasmic cis-ATR to promote DNA repair while preventing cell death; however, cells can die when DNA repair fails. Therefore, a delicate balance/equilibrium of the levels of cis- and trans-ATR is required to ensure the cellular homeostasis. In this review, we make a case that this anti-apoptotic role of cis-ATR supports oncogenesis, while Pin1 that drives the formation of trans-ATR suppresses tumor growth. We offer a potential, novel target that can be specifically targeted in cancer cells, without killing normal cells, to significantly reduce the adverse effects usually seen in cancer treatment. We also raise important issues regarding the roles of phosphorylation-dependent Pin1 isomerization of ATR in diseases and propose areas of future studies that would shed more understanding on this important cellular mechanism.
