Poètiques del desig. Alteritat i escriptura a l’obra de Gabriel Ferrater, Maria-Mercè Marçal i Enric Casasses

[cat] La present investigació parteix de la urgència de revisar la poesia catalana contemporània des dels paràmetres de la teoria literària que abracen la representació del desig. Partint de l’estreta vinculació entre aquest marc teòric i les noves formulacions del subjecte líric postmodern, hem proposat l’estudi de tres grans poètiques que han marcat, cada una d’elles en el seu context socioliterari, un punt d’inflexió a la poesia catalana des d’aquest quadre teòric: Gabriel Ferrater, Maria-Mercè Marçal i Enric Casasses. Per aquest motiu, l’objectiu central de la tesi és demostrar, a través de la categoria del desig, com l’alteritat eroticoamorosa és un dels centres de representació i experimentació dels límits del subjecte poètic i quins efectes té en la construcció de la identitat textual i en el que hem anomenat matèria-emoció. La tesi no pretén ser un estudi comparatiu dels tres autors, sinó que, capturant les tres trajectòries en paral•lel, situa cada poètica en un punt de no retorn respecte al desig i la seva representació. Atès això, és, metafòricament, el signe desig, en els seus tres plans, el que unifica els tres paradigmes que hem sotmès a anàlisi: Gabriel Ferrater com a referent, Maria-Mercè Marçal en qualitat de significat i Enric Casasses, portador del significant. El primer capítol va més enllà de la ruptura moderna entre escriptura i exaltació d’una subjectivitat única i monolítica, per comprendre en què consisteix la dissolució del jo líric en tant que fonament de l’enunciació del subjecte en el vers. És una proposta metodològica que, prenent com a centre l’intent de construcció d’una teoria del poema basada en l’expansió del jo cap a l’Altre, analitza algunes de les variables retòriques i ontològiques que coparticipen en la formulació teòrica de subjecte líric incomplet o fragmentat en el moment d’enunciar-se. D’aquesta manera, amb una voluntat de teixir uns ítems teòrics per on circuli el concepte de jo líric versus l’Altre (poesia de l’alteritat, “llei de l’assentiment”, “apropiació” de l’enunciat o, sobretot, matèria-emoció), l’escriptura poètica es concep com un joc de forces entre la performativitat del subjecte líric i la recerca de la seva pròpia subjectivitat. Aquesta crisi del subjecte i la impossibilitat de restituir una relació unilateral respecte a l’Altre, cobren una especial rellevància quan el motor o força que activa la relació d’alteritat és el moviment que impulsa el jo fora de les seves pròpies estructures per atènyer l’altre/a (subjecte desitjat) o absorbir-lo: el desig. La segona part del primer capítol està destinada a definir les aproximacions teòriques sobre la representació del desig —encercades en un posicionament postestructuralista conjuminat amb la crítica literària feminista—, que ens permeten assentar les coordenades interpretatives per portar a terme l’estudi de la formalització de tres subjectes lírics que cerquen en l’escriptura el seu propi esdevenir com a subjectes desitjants. Així és que al llarg del segon capítol hem interrogat les tres poètiques resseguint els espais comuns erigits en la nostra proposta de marc interpretatiu. Per fer-ho, ens hem centrat en Les dones i els dies de Gabriel Ferrater, amb especial èmfasi a “Teoria dels cossos”. En el cas de Maria-Mercè Marçal, hem estudiat exhaustivament el primer poemari que inaugura l’escriptura del desig lèsbic, Terra de Mai, tot establint una contigüitat temàtica amb “Sang presa” (dins de La germana, l’estrangera). I, finalment, hem resseguit la poesia d’Enric Casasses d’una forma transversal, a partir de les obres més significatives entorn al subjecte de recerca, com ara La cosa aquella, “Alquímia d’amor” (dins de Començament dels començaments i ocasió de les ocasions), D’equivocar-se així, Calç i, sobretot, Do’m. Drama en tres actes. Primer de tot, hem definit les coordenades del subjecte desitjant en relació amb el subjecte del desig, la qual cosa ens ha exigit l’anàlisi de l’enunciació del jo líric, respectivament. La recerca de les directrius fundacionals de les subjectivitats líriques —actives des del moment en què sorgeix la demanda del desig (implícita o explícita)―, han fet palesa, progressivament, la problemàtica suficiència ontològica del subjecte que deriva, al seu torn, de l’encontre amb l’altre/a. Així hem arribat a mesurar la distància inexorable que separa el jo del tu, amb resultats ben diferents. Ferrater, que anihila sorprenentment el subjecte líric, ha estat el primer port d’una singladura que, en arribar a Marçal, ens ha permès conèixer la continuïtat del ser: el despertar del desig és l’origen de la individuació dels subjectes agents del plaer en detriment de la compleció identitària. I hem navegat, finalment, fins a Casasses, qui defensa al llarg de la seva obra una individuació com a centre ètic de l’acte amorós. En una segona part, hem estudiat la representació de l’altre/a en cada corpus poètic. En el cas de Ferrater, les dones no només activen l’alteritat eroticoamorosa concreta en cada poema, sinó que, des d’un punt de vista metapoètic, esdevenen constitutives de la subjectivitat lírica en la recerca de la identitat que té lloc al llarg de Les dones i els dies. Partint de la figura de “Teseu”, poema que emmiralla i significa el procés d’escriptura poètica, hem explorat la formalització del desig en funció de les diferents representacions de la dona en paral•lel amb les posicions enunciatives del jo líric. Al llarg d’aquest recorregut, la representació del cos del desig (la fragmentació, la carícia, la mirada, etc.) i l’espai on aquest cos s’esdevé (la cambra), han estat els dos epicentres mitjançant els quals hem conclòs que la dona es presenta com un cos resistent que guia el jo líric a negar, paradoxalment, el mateix desig. La impossibilitat de satisfer el desig es manifesta, així, amb una reformulada pèrdua dels límits del subjecte desitjant. En els versos marçalians el desig emergeix com un gran torrent que arrossega al jo líric a mesurar-se en la distància que la separa de l’altra. A partir de l’altra especular, les primeres sextines de Terra de mai obren un nou ordre del jo i del tu en el discurs amorós: l’equivalència física dels cossos amants/amats extrema la fusió tant física com amorosa que es convertirà en l’acció transformadora i afirmativa de la identitat. Amb això, Marçal desarticula la gestió fal•logocèntrica del desig i l’ubica com una categoria des de la qual emprèn la construcció d’una subjectivitat lírica femenina i lèsbica. En aquest sentit, mitjançant la presència nítida d’una exploració i reconstrucció del cos de dona albirat des del desig homoeròtic, la poeta desplega la renovació d’una simbologia eròtica que configura un cosmos corporal totalment nou: cossos d’aigua i sang. Marçal busca en els fluids corporals femenins (l’aigua, la sang menstrual, la sang del trau o, fins i tot, el vòmit), la transposició dels marges corporals als textuals, convertint el poema no en un paral•lel verbal de l’experiència del desig sinó en un paral•lel corporal. En un primer moment, la representació de l’altra és indissociable de les imatges especulars (aigua o mirall). Aquesta és la fase de continuïtat, de la compleció identitària a través de l’experiència de la jouissance, i està constituïda per tres eixos: la confusió dels límits entre el jo i la seva altra, la fusió de les dues subjectivitats i l’afirmació de la unicitat amb el verb “som”. A continuació, hem resseguit com aquest “ser u” es trenca a mesura que el jo poètic es va singularitzant. Aquest segon moment és on el desig irromp al llenguatge del plaer i es converteix en una passió altament destructiva. La dissimilació amb el tu i la nostàlgia de la “fal•laç utopia d’una fusió absoluta” bolquen el poema cap a un jo poètic mutilat, que cerca un cos absent i l’espai de plenitud d’un subjecte líric que es troba irreparablement ferit (“Sang presa”). La poesia de Casasses trava la representació de l’altre amorós en la modalitat dialògica dels versos (el parlar). El fenomen de l’enunciació poètica casassiana s’emmarca en unes estructures poemàtiques que invoquen, des de l’origen, el Tu, apel•lant, així, al problema estrictament postmodern de la unicitat del jo líric i de la identitat en el procés d’escriptura. Atès això, el poema es convertirà en un dir ofert a l’Altre com a demanda del llenguatge, motiu pel qual el desig emergeix com a motor de l’escriptura poètica. Abans d’endinsar-nos específicament a l’eclosió del Tu en tant que altre amorós, ha calgut esclarir les coordenades generals del Tu en majúscules per esbossar els trets fonamentals de la significació poètica. Així, doncs, hem analitzat com es despleguen els diferents tu en l’enunciació, ja sigui quan aquest refereix al lector o a la poesia (recursos metapoètics), quan correspon a l’amor/desig (governador del subjecte de l’escriptura) i, finalment, quan el tu condensa l’altre amorós (amor particular). En aquest darrer cas, hem proposat una possible escala de transcendència del tu respecte al jo líric: d’un tu amorós totalitzador (la lluna) fins al subjecte del desig, la dona. Paral•lelament, la representació de l’amada és indissociable del concepte d’emoció lírica creada a través de la modelització del dir del jo poètic. Per aquest fet, hem classificat la irrupció del subjecte desitjat en diferents graus de referencialitat: el “tu” present, el “tu” absent i el “tu” de destinació. En un tercer apartat, hem intentat respondre a una de les grans problemàtiques que giren entorn a les escriptures del desig: és possible la seva representació? Ferrater ens enfronta davant de l’indicible. La poètica ferrateriana se situa en un distanciament deliberat de les emocions, la qual cosa circumscriu l’expressió del desig en el marc d’allò incomunicable de l’experiència. Consegüentment, hem abordat la formalització del desig a través del concepte d’imaginació tot analitzant com el poeta aconsegueix elevar l’energia emotiva del llenguatge a partir de les relacions entre la paraula i els seus absents, i com això ens permet parlar del poema en tant que matèria-emoció. Així mateix, hem conclòs que Ferrater captura l’indicible en el text jugant amb els límits representatius del llenguatge. Per abordar les escriptures del desig marçaliana i casassiana hem recorregut als plecs de la matèria-emoció encarats a l’écart: la fractura de l’epidermis del poema causada per l’erupció de la vida corporal, pulsional i afectiva del subjecte de l’escriptura. El ritme pulsional del desig (escena d’escriptura i escena amorosa) i la veu (poiesis) es converteixen en els fonaments de la construcció d’unes subjectivitats líriques que s’inscriuen en una posició femenina, allà on el cos amb estat d’apetència cerca la continuïtat en l’escriptura. Concretament, hem resseguit la formalització de l’absència de l’altra en els versos de Marçal, la qual recorre a figuracions com l’espera, el buit, la desfeta del mirall, l’assassinat dels cossos en plenitud, entre altres imatges que activen el salt de l’eros al thanatos; així com, també, les estructures interrogatives que signifiquen la impossibilitat d’experimentar el desig del desig de l’altra. Respecte a l’obra de Casasses, el poeta troba en la forma dramàtica el mitjà idoni per experimentar les possibilitats de la representació del desig: Do’m. Mitjançant una exegesi detallada del drama, hem pogut concloure que, tal com postula Barthes, l’única construcció textual possible d’allò amorós es troba en formular el que té d’intractable, i això només es pot representar a partir de l’acció mateixa. Talment, Casasses porta a l’extrem la modalitat dialògica pròpia de la seva poesia per escenificar l’encontre amorós i la construcció in progress del subjecte desitjant a través del dir-se l’amor. Finalment, la investigació intenta oferir una resposta al voltant de la conjunció desig, subjectivitat lírica i identitat. Aquestes tres coordenades ens permeten elevar les diferents representacions del desig a l’alçada de les millors poètiques contemporànies. L’ètica i l’estètica ferrateriana es congreguen en l’espai de l’erotisme moral. Ferrater concep el vers com un mètode fenomenològic a través del qual inscriu una actitud poètica que no es pot pensar sense la formalització del subjecte desitjant. Atès això, amb Les dones i els dies s’inaugura la categoria del desig en relació amb els límits d’expressió del subjecte líric. Marçal obre les portes a l’espai literari femení i lèsbic amb una escriptura poètica creadora de nous àmbits per a l’expressió del desig. La cerca d’un nou ordre simbòlic en el llenguatge poètic està estretament vinculada amb la construcció d’una subjectivitat tant política com poètica, un dels trets principals de la qual és la reivindicació i afirmació del plaer sexual femení. D’aquesta manera, el desig a l’obra de la poeta és portador d’una actitud i praxi política que troba la seva màxima expressió en la conquesta d’una llengua abolida. Per acabar, Casasses invoca l’espai de la paraula viva per articular l’acompliment de la funció poètica. A través de la poesia recitada, ja sigui des d’un punt de vista teòric com en la seva performance escènica, construeix una nova i fundacional experiència poètica que troba el seu paral•lel amb l’experiència amorosa. En aquest nou espai de circulació de la paraula poètica hi situa una subjectivitat lírica fundada en el moviment ètic cap a l’altre encarnat en el cos, la veu i el ritme.

Silene as a model system in ecology and evolution.

The genus Silene, studied by Darwin, Mendel and other early scientists, is re-emerging as a system for studying interrelated questions in ecology, evolution and developmental biology. These questions include sex chromosome evolution, epigenetic control of sex expression, genomic conflict and speciation. Its well-studied interactions with the pathogen Microbotryum has made Silene a model for the evolution and dynamics of disease in natural systems, and its interactions with herbivores have increased our understanding of multi-trophic ecological processes and the evolution of invasiveness. Molecular tools are now providing new approaches to many of these classical yet unresolved problems, and new progress is being made through combining phylogenetic, genomic and molecular evolutionary studies with ecological and phenotypic data.

Antigenicity and immunogenicity of Melan-A/MART-1 derived peptides as targets for tumor reactive CTL in human melanoma.

Some cancer patients mount spontaneous T- and B-cell responses against their tumor cells. Autologous tumor reactive CD8 cytolytic T lymphocyte (CTL) and CD4 T-cell clones as well as antibodies from these patients have been used for the identification of genes encoding the target antigens. This knowledge opened the way for new approaches to the immunotherapy of cancer. In this review, we describe the characterization of the structure-function properties of the melanocyte/melanoma tumor antigen Melan-A/MART-1, the assessment of the T-cell repertoire available against this antigen in healthy individuals, and the analysis of naturally acquired and/or vaccine-induced CTL responses to this antigen in patients with metastatic melanoma.

Neurotrophic activity of human adipose stem cells isolated from deep and superficial layers of abdominal fat.

New approaches to the clinical treatment of traumatic nerve injuries may one day utilize stem cells to enhance nerve regeneration. Adipose-derived stem cells (ASC) are found in abundant quantities and can be harvested by minimally invasive procedures that should facilitate their use in such regenerative applications. We have analyzed the properties of human ASC isolated from the deep and superficial layers of abdominal fat tissue obtained during abdominoplasty procedures. Cells from the superficial layer proliferate significantly faster than those from the deep layer. In both the deep and superficial layers, ASC express the pluripotent stem cell markers oct4 and nanog and also the stro-1 cell surface antigen. Superficial layer ASC induce the significantly enhanced outgrowth of neurite-like processes from neuronal cell lines when compared with that of deep layer cells. However, analysis by reverse transcription with the polymerase chain reaction and by enzyme-linked immunosorbent assay has revealed that ASC isolated from both layers express similar levels of the following neurotrophic factors: nerve growth factor, brain-derived neurotrophic factor and glial-derived neurotrophic factor. Thus, human ASC show promising potential for the treatment of traumatic nerve injuries. In particular, superficial layer ASC warrant further analysis of their neurotrophic molecules.

A novel procedure for establishing clinching parameters for high strength steel sheet

The building industry has a particular interest in using clinching as a joining method for frame constructions of light-frame housing. Normally many clinch joints are required in joining of frames.In order to maximise the strength of the complete assembly, each clinch joint must be as sound as possible. Experimental testing is the main means of optimising a particular clinch joint. This includes shear strength testing and visual observation of joint cross-sections. The manufacturers of clinching equipment normally perform such experimental trials. Finite element analysis can also be used to optimise the tool geometry and the process parameter, X, which represents the thickness of the base of the joint. However, such procedures require dedicated software, a skilled operator, and test specimens in order to verify the finite element model. In addition, when using current technology several hours' computing time may be necessary. The objective of the study was to develop a simple calculation procedure for rapidly establishing an optimum value for the parameter X for a given tool combination. It should be possible to use the procedure on a daily basis, without stringent demands on the skill of the operator or the equipment. It is also desirable that the procedure would significantly decrease thenumber of shear strength tests required for verification. The experimental workinvolved tests in order to obtain an understanding of the behaviour of the sheets during clinching. The most notable observation concerned the stage of the process in which the upper sheet was initially bent, after which the deformation mechanism changed to shearing and elongation. The amount of deformation was measured relative to the original location of the upper sheet, and characterised as the C-measure. By understanding in detail the behaviour of the upper sheet, it waspossible to estimate a bending line function for the surface of the upper sheet. A procedure was developed, which makes it possible to estimate the process parameter X for each tool combination with a fixed die. The procedure is based on equating the volume of material on the punch side with the volume of the die. Detailed information concerning the behaviour of material on the punch side is required, assuming that the volume of die does not change during the process. The procedure was applied to shear strength testing of a sample material. The sample material was continuously hot-dip zinc-coated high-strength constructional steel,with a nominal thickness of 1.0 mm. The minimum Rp0.2 proof stress was 637 N/mm2. Such material has not yet been used extensively in light-frame housing, and little has been published on clinching of the material. The performance of the material is therefore of particular interest. Companies that use clinching on a daily basis stand to gain the greatest benefit from the procedure. By understanding the behaviour of sheets in different cases, it is possible to use data at an early stage for adjusting and optimising the process. In particular, the functionality of common tools can be increased since it is possible to characterise the complete range of existing tools. The study increases and broadens the amount ofbasic information concerning the clinching process. New approaches and points of view are presented and used for generating new knowledge.

Supply chain integration: studies on linking customer responsiveness and operational efficiency in logistics policy planning

Abstract The research problem in the thesis deals with improving the responsiveness and efficiency of logistics service processes between a supplier and its customers. The improvement can be sought by customizing the services and increasing the coordination of activities between the different parties in the supply chain. It is argued that to achieve coordination the parties have to have connections on several levels. In the framework employed in this research, three contexts are conceptualized at which the linkages can be planned: 1) the service policy context, 2) the process coordination context, and 3) the relationship management context. The service policy context consists of the planning methods by which a supplier analyzes its customers' logistics requirements and matches them with its own operational environment and efficiency requirements. The main conclusion related to the service policy context is that it is important to have a balanced selection of both customer-related and supplier-related factors in the analysis. This way, while the operational efficiency is planned a sufficient level of service for the most important customers is assured. This kind of policy planning involves taking multiple variables into the analysis, and there is a need to develop better tools for this purpose. Some new approaches to deal with this are presented in the thesis.The process coordination context and the relationship management context deal with the issues of how the implementation of the planned service policies can be facilitated in an inter-organizational environment. Process coordination includes typically such mechanisms as control rules, standard procedures and programs, but inhighly demanding circumstances more integrative coordination mechanisms may be necessary. In the thesis the coordination problems in third-party logistics relationship are used as an example of such an environment. Relationship management deals with issues of how separate companies organize their relationships to improve the coordination of their common processes. The main implication related to logistics planning is that by integrating further at the relationship level, companies can facilitate the use of the most efficient coordination mechanisms and thereby improve the implementation of the selected logistics service policies. In the thesis, a case of a logistics outsourcing relationship is used to demonstrate the need to address the relationship issues between the service provider andthe service buyer before the outsourcing can be done.The dissertation consists of eight research articles and a summarizing report. The principal emphasis in the articles is on the service policy planning context, which is the main theme of six articles. Coordination and relationship issues are specifically addressed in two of the papers.

R&D Performance Analysis: Case Studies on the Challenges and Promotion of the Evaluation and Measurement of R&D

Due to the intense international competition, demanding, and sophisticated customers, and diverse transforming technological change, organizations need to renew their products and services by allocating resources on research and development (R&D). Managing R&D is complex, but vital for many organizations to survive in the dynamic, turbulent environment. Thus, the increased interest among decision-makers towards finding the right performance measures for R&D is understandable. The measures or evaluation methods of R&D performance can be utilized for multiple purposes; for strategic control, for justifying the existence of R&D, for providing information and improving activities, as well as for the purposes of motivating and benchmarking. The earlier research in the field of R&D performance analysis has generally focused on either the activities and considerable factors and dimensions - e.g. strategic perspectives, purposes of measurement, levels of analysis, types of R&D or phases of R&D process - prior to the selection of R&Dperformance measures, or on proposed principles or actual implementation of theselection or design processes of R&D performance measures or measurement systems. This study aims at integrating the consideration of essential factors anddimensions of R&D performance analysis to developed selection processes of R&D measures, which have been applied in real-world organizations. The earlier models for corporate performance measurement that can be found in the literature, are to some extent adaptable also to the development of measurement systemsand selecting the measures in R&D activities. However, it is necessary to emphasize the special aspects related to the measurement of R&D performance in a way that make the development of new approaches for especially R&D performance measure selection necessary: First, the special characteristics of R&D - such as the long time lag between the inputs and outcomes, as well as the overall complexity and difficult coordination of activities - influence the R&D performance analysis problems, such as the need for more systematic, objective, balanced and multi-dimensional approaches for R&D measure selection, as well as the incompatibility of R&D measurement systems to other corporate measurement systems and vice versa. Secondly, the above-mentioned characteristics and challenges bring forth the significance of the influencing factors and dimensions that need to be recognized in order to derive the selection criteria for measures and choose the right R&D metrics, which is the most crucial step in the measurement system development process. The main purpose of this study is to support the management and control of the research and development activities of organizations by increasing the understanding of R&D performance analysis, clarifying the main factors related to the selection of R&D measures and by providing novel types of approaches and methods for systematizing the whole strategy- and business-based selection and development process of R&D indicators.The final aim of the research is to support the management in their decision making of R&D with suitable, systematically chosen measures or evaluation methods of R&D performance. Thus, the emphasis in most sub-areas of the present research has been on the promotion of the selection and development process of R&D indicators with the help of the different tools and decision support systems, i.e. the research has normative features through providing guidelines by novel types of approaches. The gathering of data and conducting case studies in metal and electronic industry companies, in the information and communications technology (ICT) sector, and in non-profit organizations helped us to formulate a comprehensive picture of the main challenges of R&D performance analysis in different organizations, which is essential, as recognition of the most importantproblem areas is a very crucial element in the constructive research approach utilized in this study. Multiple practical benefits regarding the defined problemareas could be found in the various constructed approaches presented in this dissertation: 1) the selection of R&D measures became more systematic when compared to the empirical analysis, as it was common that there were no systematic approaches utilized in the studied organizations earlier; 2) the evaluation methods or measures of R&D chosen with the help of the developed approaches can be more directly utilized in the decision-making, because of the thorough consideration of the purpose of measurement, as well as other dimensions of measurement; 3) more balance to the set of R&D measures was desired and gained throughthe holistic approaches to the selection processes; and 4) more objectivity wasgained through organizing the selection processes, as the earlier systems were considered subjective in many organizations. Scientifically, this dissertation aims to make a contribution to the present body of knowledge of R&D performance analysis by facilitating dealing with the versatility and challenges of R&D performance analysis, as well as the factors and dimensions influencing the selection of R&D performance measures, and by integrating these aspects to the developed novel types of approaches, methods and tools in the selection processes of R&D measures, applied in real-world organizations. In the whole research, facilitation of dealing with the versatility and challenges in R&D performance analysis, as well as the factors and dimensions influencing the R&D performance measure selection are strongly integrated with the constructed approaches. Thus, the research meets the above-mentioned purposes and objectives of the dissertation from the scientific as well as from the practical point of view.

ME - Mobile Electronic Personality

Digital services require personal information for a variety of reasons. Due to advances in communication technology, new types of services are evolving alongwith traditional Internet services. Due to the diversity of services, the traditional approaches to personal information handling designed for Internet services are inadequate. Therefore, new approaches are necessary. In this thesis, a solution where personal information is stored in and accessed from the user's mobile device is presented. This approach is called Mobile Electronic Personality (ME). The ME approach is compared to the existing approaches which rely on a database either at a service, a trusted third party or a client program. Various personal information properties are taken into account in the comparison of storage locations. The thesis presents both the internal and the communication architecture of the ME. The internal architecture defines how the information is stored in the mobile device. The communication architecture defines how the information can be accessed by different types of services from the ME. The use of the architecture is described for services in different environments. A simple ME based solution for the authentication of a user is defined. The authentication of service, which is required to protect the privacy of the users is also presented.

Dynamics of Appropriability - Finding a Balance between Efficiency and Strength in the Appropriability Regime

Building and sustaining competitive advantage through the creation of market imperfections is challenging in a constantly changing business environment - particularly since the sources of such advantages are increasingly knowledge-based. Facilitated by improved networks and communication, knowledge spills over to competitors more easily than before,thus creating an appropriability problem: the inability of an innovating firm to utilize its innovations commercially. Consequently, as the importance of intellectual assets increases, their protection also calls for new approaches. Companies have various means of protection at their disposal, and by taking advantage of them they can make intangibles more non-transferable and prevent, or at leastdelay, imitation of their most crucial intellectual assets. However, creating barriers against imitation has another side to it, and the transfer of knowledge in situations requiring knowledge sharing may be unintentionally obstructed. Theaim of this thesis is to increase understanding of how firms can balance knowledge protection and sharing so as to benefit most from their knowledge assets. Thus, knowledge protection is approached through an examination of the appropriability regime of a firm, i.e., the combination of available and effective means ofprotecting innovations, their profitability, and the increased rents due to R&D. A further aim is to provide a broader understanding of the formation and structure of the appropriability regime. The study consists of two parts. The first part introduces the research topic and the overall results of the study, and the second part consists of six complementary research publications covering various appropriability issues. The thesis contributes to the existing literature in several ways. Although there is a wide range of prior research on appropriability issues, a lot of it is restricted either to the study of individual appropriability mechanisms, or to comparing certain features of them. These approaches are combined, and the relevant theoretical concepts are clarified and developed. In addition, the thesis provides empirical evidence of the formation of the appropriability regime, which is consequently presented as an adaptive process. Thus, a framework is provided that better corresponds to the complex reality of the current business environment.

Breeding, genetic and genomic of citrus for disease resistance

Although the citriculture is one of the most important economic activities in Brazil, it is based on a small number of varieties. This fact has contributed for the vulnerability of the culture regarding the phytosanitary problems. A higher number of varieties/genotypes with potential for commercial growing, either for the industry or fresh market, has been one of the main objectives of citrus breeding programs. The genetic breeding of citrus has improved, in the last decades, due to the possibility of an association between biotechnological tools and classical methods of breeding. The use of molecular markers for early selection of zygotic seedlings from controlled crosses resulted in the possibility of selection of a high number of new combination and, as a consequence, the establishment of a great number of hybrids in field experiments. The faster new tools are incorporated in the program, the faster is possibility to reach new genotypes that can be tested as a new variety. Good traits should be kept or incorporate, whereas bad traits have to be excluded or minimized in the new genotype. Scion and rootstock can not be considered separately, and graft compatibility, fruit quality and productivity are essential traits to be evaluated in the last stages of the program. The mapping of QTLs has favored breeding programs of several perennial species and in citrus it was possible to map several characteristics with qualitative and quantitative inheritance. The existence of linkage maps and QTLs already mapped, the development of EST and BAC library and the sequencing of the Citrus complete genome altogether make very demanding and urgent the exploration of such data to launch a wider genetic study of citrus. The rising of information on genome of several organisms has opened new approaches looking for integration between breeding, genetic and genome. Genome assisted selection (GAS) involves more than gene or complete genome sequencing and is becoming an import support in breeding programs of annual and perennial species. An huge information amount can be derivate from genome analysis. The use and benefit of such informations will depend on the genetic basis of the breeding program.

Surgery Versus Radiotherapy for Early Oropharyngeal Tumors: a Never-Ending Debate.

OPINION STATEMENT: Therapeutic options for early stage oropharyngeal squamous cell carcinoma (OPSCC) include both surgery and radiotherapy as single treatment modality. Retrospective data reporting on locoregional control and survival rates in early stage OPSCC have shown equivalent efficacy, although no prospective randomized trials are available to confirm these results. Given the assumed comparable oncologic results in both groups, complication rates and functional outcomes associated with each modality play a major role when making treatment decisions. Radiotherapy is used preferentially in many centers because few trials have reported higher complication rates in surgical patients. However, these adverse effects were mainly due to traditional invasive open surgical approaches used for access to the oropharynx. In order to decrease the morbidity of these techniques, transoral surgical (TOS) approaches have been developed progressively. They include transoral laser microsurgery (TLM), transoral robotic surgery (TORS), and conventional transoral techniques. Meta-analysis comparing these new approaches with radiotherapy showed equivalent efficacy in terms of oncologic results. Furthermore, studies reporting on functional outcomes in patients undergoing TOS for OPSCC did not show major long-term functional impairment following treatment. Given the abovementioned statements, it is our practice to treat early stage OPSCC as follows: whenever a single modality treatment seems feasible (T1-2 and N0-1), we advocate TOS resection of the primary tumor associated with selective neck dissection, as indicated. In our opinion, the advantage of this approach relies on the possibility to stratify the risk of disease progression based on the pathological features of the tumor. Depending on the results, adjuvant radiation treatment or chemoradiotherapy can be chosen for high-risk patients. For tumors without adverse features, no adjuvant treatment is given. This approach also allows prevention of potential radiation-induced late complications while keeping radiotherapy as an option for any second primary lesions whenever needed. Definitive radiotherapy is generally reserved for selected patients with specific anatomical location associated with poor functional outcome following surgery, such as tumor of the soft palate, or for patients with severe comorbidities that do not allow surgical treatment.

A reappraisal of 'International Stratigraphic Lexicon' and the need for the creation named units critical catalogues

Analysis of stratigraphic terminology and classification, shows that time-related stratigraphic units, which by definition have a global extent, are the concern of international cornrnissions and committees of the intemational Union of Geological Sciences (IUGS) . In contrast, lithostratigraphic, and other closely related units, are regional in extent and are catalogued in the International Stratigraphic Lexicon (ISL), the last volume of which, was published in 1987. Tlie intemational Commission on Stratigraphy (ICS) is currently attempting to revitalize the publication of ISL, given that the information contained in published volumes has never been updated, and that there has been a significant increase in stratigraphic research in recent decades. The proliferation of named units in the South Pyrenean and Ebro Basin Paleogene is evaluated to illustrate the extent of the problem. Moreover, new approaches to stratigraphic analysis have led to the naming of genetic units according to similar guidelines followed in the naming of descnptive or lithostratigraphic units. This has led to considerable confusion. The proposal to revitalize the ISL is accepted as part of the solution, that should also include the publication of critica1 catalogues, and the creation of norms for genetic unit terminology.

International STakeholder NETwork (ISTNET): creating a developmental neurotoxicity (DNT) testing road map for regulatory purposes.

A major problem in developmental neurotoxicity (DNT) risk assessment is the lack of toxicological hazard information for most compounds. Therefore, new approaches are being considered to provide adequate experimental data that allow regulatory decisions. This process requires a matching of regulatory needs on the one hand and the opportunities provided by new test systems and methods on the other hand. Alignment of academically and industrially driven assay development with regulatory needs in the field of DNT is a core mission of the International STakeholder NETwork (ISTNET) in DNT testing. The first meeting of ISTNET was held in Zurich on 23-24 January 2014 in order to explore the concept of adverse outcome pathway (AOP) to practical DNT testing. AOPs were considered promising tools to promote test systems development according to regulatory needs. Moreover, the AOP concept was identified as an important guiding principle to assemble predictive integrated testing strategies (ITSs) for DNT. The recommendations on a road map towards AOP-based DNT testing is considered a stepwise approach, operating initially with incomplete AOPs for compound grouping, and focussing on key events of neurodevelopment. Next steps to be considered in follow-up activities are the use of case studies to further apply the AOP concept in regulatory DNT testing, making use of AOP intersections (common key events) for economic development of screening assays, and addressing the transition from qualitative descriptions to quantitative network modelling.

A história da ciência e o objeto de seu estudo: confrontos entre a ciência periférica, a ciência central e a ciência marginal

The historiography of science has undergone a profound change from the traditional perspective of a few decades ago, according to which only mainstream science was worth pursuing as a research field. Such a restricted outlook was not conducive to a thorough understanding of the whole process of the construction of science. New approaches have breathed new life into the discipline, taking into account not only scientific endeavours from so-called peripheral societies, but also from different quarters within or close to the central groups. From this a new and far more interesting view has emerged, showing a complex and richer texture.
