The construction of national identity as a developmental process from childhood to adolescence in Catalonia

La idea que per entendre alguna cosa hem d'entendre el procés pel qual s'ha produït va ser assumida des de l'origen de l'estudi "La construcció de la identitat nacional com a procés de desenvolupament des de la infància a l'adolescència a Catalunya". Per tal d'estudiar el procés de desenvolupament relacionat amb la construcció de la identitat nacional, no és suficient considerar-lo en el seu context social, sinó que és necessari considerar la seva construcció social. Tres objectius principals van orientar el nostre estudi . Primer, indagar si els processos de categorització, identificació, coneixement, imatge, avaluació i afecte són també elements implicats en la construcció de la identitat nacional des de la infància a l'adolescència. Segon investigar el procés de desenvolupament d'aquests elements des dels 6 anys fins als 15 anys per contribuir amb dades a I'explicació sobre com es desenvolupa del coneixement social. Tres són les explicacions principals; la primera que es basa en processos cognitius d'inclusió-decentració; la segona, si aquest desenvolupament es dóna en cercles concèntrics des de I'interior (contextos quotidians) fins a l'exterior (amb intercanvis més amples i una educació formal envers la vida social); i la tercera, si el desenvolupament del coneixement social d'allò més immediat i directe es reorganitzat i adquireix nous significats per la integració dels elements més generals i abstractes. Tercer, donat el fet que el 50% de les famílies tenen el català com a llengua materna, hem estudiat la influència de la llengua o llengües utilitzades en el context familiar en el procés de construcció de la identitat nacional. Es va dissenyar una entrevista individual seguint una estructura amb les parts següents: identificació subjectiva i identificació nacional; coneixement dels països; estereotips, avaluació i sentiments, i entorn social. La mostra del present estudi va estar formada per 495 nens i adolescents de 6, 9, 12 i 15 anys d'edat. Es va utilitzar per cada grup un número similar de nens i nenes. La mostra es va dividir en tres grups segons la o les llengües utilitzades pel nen o nena en el seu context familiar. Tres van ser les categones lingüístiques utilitzades: castellà, nens que només utilitzin el castellà a casa; català, nens que només usen el català en el context familiar; i bilingües, nens que utilitzin tots dos idiomes a casa. Aquestes categories lingüístiques s'han utilitzat com a indicador dels contextos familiars. Dues conclusions principals es poden extreure d'aquest estudi. Primer, I'ús de categories nacionals no és una conseqüència del procés cognitiu d'inclusió-decentració ni en cercles concentrics (concret/abstracte). La idea d'un procés del món en paral·lel, d'un coneixement que integra simultàniament creences i sentiments de l'ambient concret o proper i de l'abstracte o llunyà pot explicar millor els nostres resultats. Els nens aprenen i pensen sobre la vida quotidara, les característiques de l'ambient, la informació circulant en el seu entom social i la importància o els diferents nivells de coneixement depenent del context. Els nens integren la informació que està circulant en el seu ambient i construeixen un món que necessàriament no ha de coincidir amb el món deis adults, però que els ajuda a comunicar-se i a entendre les situacions en les quals estan immersos. Els nens més joves són capaços d'utilitzar categories nacionals de manera similar als adolescents. Segon, la identitat nacional a Catalunya es construeix al voltant del nucli de la llengua parlada a casa. A través de tot I'estudi es pot veure un resultat consistent i reiterat. Els infants d'un entom familiar en què s'usa només el castellà s'identifiquen com a pertanyents a tots dos grups nacionals, Espanyol i Català. Els infants d'un entom familiar que utilitzen només el català s'identifiquen com a pertanyents només al grup Català. Aquestes identificacions guien com aquests nens avaluen i senten envers el propi grup nacional i els altres. A més, sembla que el context sòcio-polític és un vehicle important en la transmissió de les estructures de semblances i que I'estructura d'afecte es transmet principalment a través de I'entom familiar.

Innovaation kehittäminen yritysverkostolle, Case: Projektihallinta

Työn tavoitteena on kehittää arvoinnovaatio yritysverkostolle. Arvoinnovaation teoreettisen viitekehyksen konkretisoimiseksi ja arvioimiseksi käytetään työssä kohteena ProPortfolio - ohjelmistotuotetta sekä sen kehittämistyössä saatuja kokemuksia. ProPortfolio on vuosina 2001-2004 kehitetty mobiiliin teknologiaan perustuva ohjelmistosovellus. ProPortfolio ohjelmisto on liikkeenjohdon konsulttiyritys Tuloskunto Oy:n johdolla ja TEKES:n rahoittamassa hankkeessa kehitetty pientaloprojektien toteuttajaverkoston toiminnanohjausjärjestelmä. Pitkäaikaisen kilpailuedun saavuttaminen erottumalla kilpailijoiden massasta on kasvava haaste yrityksille. Tutkijoiden Kimin ja Mauborgnen kehittämän arvoinnovaation ja strategisen suunnittelun prosessin lähtökohtana on kilpailun kiertäminen differoitumalla kilpailijoista ja uusien markkinoiden luominen. Perinteisen strategisen ajattelutavan mukaan yritykset voivat tuottaa korkeampaa arvoaasiakkaille korkeammin kustannuksin tai kohtuullista arvoa pienemmin kustannuksin. Eli strateginen asemointi perustuu valintaan differoitumisen ja kustannusjohtajuuden välillä (Porter,1985). Arvoinnovaatioon perustuvassa asemoinnissa tavoitellaan sekä differoitumista että kustannusjohtajuutta samanaikaisesti. Arvoinnovaation keskeisimmät kriteerit täyttyivät kehityshankkeen lopputuloksena syntyneessä ProPortfolio -ohjelmistotuotteessa. Tämän työn pohjalta voidaan todeta, että Kimin ja Mauborgnen kehittämä strategian suunnitteluprosessi on laaja ja vaativa. Arvoinnovaatio syntyy harvoin hetkellisenä oivalluksena, vaan kehittyy järjestelmällisen työskentelyn tuloksena. ProPortfolio -ohjelmistotuotteen arvoinnovaation muodostuminen perustui kehityshankkeen onnistuneeseen asiakastarpeiden tunnistamiseen ja ennakoimiseen. Selkeän kuvan hahmottuminen ratkaistavista ongelmista auttoi asemoimaan hankkeen jatkokehitystyön oikein ja loi edellytykset arvoinnovaation muodostumiselle. Tutkijat Kim jaMauborgne ovat haastaneet perinteiset strategiatyöskentelyn mallit. Tutkimustuloksiinsa pohjautuen he ovat kehittäneet uuden arvoinnovaatioon perustuvan strategisen suunnittelun teoreettisen viitekehikon ja prosessin. Nämä mallit tulevat varmasti jättämään pysyvän jäljen strategiatyöskentelyn nykykäytäntöihin.

Lääkintätekniikan ohjaaminen prosessijohtamisella ja prosessien kehittäminen

Tässä työssä tutkitaan sairaalan lääkintätekniikkaa ja kuinka sen toimintaa voitaisiin ohjata prosessijohtamisella. Työssä on tunnistettu sekä määritetty ja kuvattu lääkintätekniikan prosessit, suunniteltu mittausmenetelmät ja annettu prosesseille kehityssuosituksia. Työn merkittävimmät tulokset keskittyvät nykyisten järjestelmien kehittämiseen ja suorituskyvyn mittaamisen haastavuuteen. Tutkimuksen tuloksena havaittiin, että lääkintätekniikan prosessijohtaminen on mahdollista, mutta vaikutukset suorituskykyyn olisivat pienet. Suositukset kehitystoimenpiteisiin keskittyvät paljon tiedon jakamiseen, koska tutkimuksessa teetetyssä kyselyssä ilmeni palveltavien osastojen haluavan paljon tietoa lääkintätekniikalta. Tietoa tullaan jakamaan nykyisen lääkintätekniikan sovelluksen Mequsoftin välityksellä, koska lähestulkoon kaikki olennainen tieto kirjataan jo sinne.

Controle feedback de nível baseado em sensor de imagem aplicado ao equipamento misturador-decantador à inversão de fases (MDIF®)

The treatment of wastewaters contaminated with oil is of great practical interest and it is fundamental in environmental issues. A relevant process, which has been studied on continuous treatment of contaminated water with oil, is the equipment denominated MDIF® (a mixer-settler based on phase inversion). An important variable during the operation of MDIF® is the water-solvent interface level in the separation section. The control of this level is essential both to avoid the dragging of the solvent during the water removal and improve the extraction efficiency of the oil by the solvent. The measurement of oil-water interface level (in line) is still a hard task. There are few sensors able to measure oil-water interface level in a reliable way. In the case of lab scale systems, there are no interface sensors with compatible dimensions. The objective of this work was to implement a level control system to the organic solvent/water interface level on the equipment MDIF®. The detection of the interface level is based on the acquisition and treatment of images obtained dynamically through a standard camera (webcam). The control strategy was developed to operate in feedback mode, where the level measure obtained by image detection is compared to the desired level and an action is taken on a control valve according to an implemented PID law. A control and data acquisition program was developed in Fortran to accomplish the following tasks: image acquisition; water-solvent interface identification; to perform decisions and send control signals; and to record data in files. Some experimental runs in open-loop were carried out using the MDIF® and random pulse disturbances were applied on the input variable (water outlet flow). The responses of interface level permitted the process identification by transfer models. From these models, the parameters for a PID controller were tuned by direct synthesis and tests in closed-loop were performed. Preliminary results for the feedback loop demonstrated that the sensor and the control strategy developed in this work were suitable for the control of organic solvent-water interface level

Automação de um sistema rotatório para secagem do rejeito de maracujá

The rotary dryer is one of the most used equipments in processing industries. Its automatic control mode of operation is important specially to keep the moisture content of the final product in the desired value. The classical control strategies, like PID (proportional integral derivative) control, are largely used in the industrial sector because of its robustness and because they are easy to be implemented. In this work, a data acquisition system was implemented for monitoring the most relevant process variables, like: both inlet and outlet drying air temperature, dryer rotation, outlet air speed and humidity, and mass of the final product. Openloop tests were realized to identify a mathematical model able to represent the drying process for the rotary system. From this model, a PID controller was tuned using a direct synthesis method, assuming a first order trajectory. The PID controller was implemented in the system in order to control the inlet drying air temperature. By the end, closedloop tests (operating in automatic mode) were realized to observe the controller performance, and, after setting the best tune, experiments were realized using passion fruit seeds as raw material. The experiments realized in closedloop showed a satisfactory performance by the implemented control strategy for the drying air temperature of the rotary system

Avaliação ambiental em empresas do distrito industrial Antônio Crepaldi, Presidente Prudente/SP

The sustainable development is the center of many discussions about the environment, economy and society. Environmental issues bring out problems with the fauna and flora, water resources, land use, population growth, residues, basic sanitation, and others. In this sense, the aim of the present work was to develop an environmental diagnostics and propose measures to mitigate the most significant environmental impacts generated by four enterprises in Antonio Crepaldi Industrial District, located at the city of Presidente Prudente/SP. In the study, it was used the methodology proposed by Moreira (2006), and it was done the following activities: monitoring and analyses of the production process, identification of potential environmental aspects and impacts; assessment of the impacts according to its nature, relevance and significance; proposition of measures to mitigate the critical impacts. As a final result, it was obtained an environmental diagnosis about the situation of each of the four companies studied, and it was possible to know the level of criticality of the impacts in each one, and proposing mitigation measures to control or minimizing them, bringing many benefits to the organization

Science publication workshops as a strategy to improve the visibility of scholarly production: the experience of the University of Sao Paulo (USP) - Brazil

The objective of this work is to present the experience of workshops that have been developed at the University of Sao Paulo by the Integrated Library System in partnership with Research Commission. The poster presents the main results of workshops that were made in 2011, in two knowledge areas: life science and engineering, about science publication processes, and directed to graduates, pos-doctorates, researchers, professors and library staff. The realization of workshops made possible identifies gaps in different aspects of scholarly communication such as research planning, search information strategy, information organization, submission process, identification of journals with high impact, and so on, areas where professors and librarians can help. Besides, workshops reveal that the majority of participants believe in its importance. Despite the ubiquity of digital technology that transversely impacts all academic activities, it is imperative to promote efforts to find a convergence between information and media literacy in higher education and university research activities. This is particularly important when we talk about how science is produced, communicated and preserved for future use. In this scenario, libraries and librarians assume a new, more active and committed role.

Solute transport in crystalline rocks at Äspö — I: Geological basis and model calibration

Water-conducting faults and fractures were studied in the granite-hosted A¨ spo¨ Hard Rock Laboratory (SE Sweden). On a scale of decametres and larger, steeply dipping faults dominate and contain a variety of different fault rocks (mylonites, cataclasites, fault gouges). On a smaller scale, somewhat less regular fracture patterns were found. Conceptual models of the fault and fracture geometries and of the properties of rock types adjacent to fractures were derived and used as input for the modelling of in situ dipole tracer tests that were conducted in the framework of the Tracer Retention Understanding Experiment (TRUE-1) on a scale of metres. After the identification of all relevant transport and retardation processes, blind predictions of the breakthroughs of conservative to moderately sorbing tracers were calculated and then compared with the experimental data. This paper provides the geological basis and model calibration, while the predictive and inverse modelling work is the topic of the companion paper [J. Contam. Hydrol. 61 (2003) 175]. The TRUE-1 experimental volume is highly fractured and contains the same types of fault rocks and alterations as on the decametric scale. The experimental flow field was modelled on the basis of a 2D-streamtube formalism with an underlying homogeneous and isotropic transmissivity field. Tracer transport was modelled using the dual porosity medium approach, which is linked to the flow model by the flow porosity. Given the substantial pumping rates in the extraction borehole, the transport domain has a maximum width of a few centimetres only. It is concluded that both the uncertainty with regard to the length of individual fractures and the detailed geometry of the network along the flowpath between injection and extraction boreholes are not critical because flow is largely one-dimensional, whether through a single fracture or a network. Process identification and model calibration were based on a single uranine breakthrough (test PDT3), which clearly showed that matrix diffusion had to be included in the model even over the short experimental time scales, evidenced by a characteristic shape of the trailing edge of the breakthrough curve. Using the geological information and therefore considering limited matrix diffusion into a thin fault gouge horizon resulted in a good fit to the experiment. On the other hand, fresh granite was found not to interact noticeably with the tracers over the time scales of the experiments. While fracture-filling gouge materials are very efficient in retarding tracers over short periods of time (hours–days), their volume is very small and, with time progressing, retardation will be dominated by altered wall rock and, finally, by fresh granite. In such rocks, both porosity (and therefore the effective diffusion coefficient) and sorption Kds are more than one order of magnitude smaller compared to fault gouge, thus indicating that long-term retardation is expected to occur but to be less pronounced.

Valve friction and nonlinear process model closed-loop identification

Among several process variability sources, valve friction and inadequate controller tuning are supposed to be two of the most prevalent. Friction quantification methods can be applied to the development of model-based compensators or to diagnose valves that need repair, whereas accurate process models can be used in controller retuning. This paper extends existing methods that jointly estimate the friction and process parameters, so that a nonlinear structure is adopted to represent the process model. The developed estimation algorithm is tested with three different data sources: a simulated first order plus dead time process, a hybrid setup (composed of a real valve and a simulated pH neutralization process) and from three industrial datasets corresponding to real control loops. The results demonstrate that the friction is accurately quantified, as well as ""good"" process models are estimated in several situations. Furthermore, when a nonlinear process model is considered, the proposed extension presents significant advantages: (i) greater accuracy for friction quantification and (ii) reasonable estimates of the nonlinear steady-state characteristics of the process.

Analysis of dynamic process models for structural insight and model reduction .1. Structural identification measures

An important consideration in the development of mathematical models for dynamic simulation, is the identification of the appropriate mathematical structure. By building models with an efficient structure which is devoid of redundancy, it is possible to create simple, accurate and functional models. This leads not only to efficient simulation, but to a deeper understanding of the important dynamic relationships within the process. In this paper, a method is proposed for systematic model development for startup and shutdown simulation which is based on the identification of the essential process structure. The key tool in this analysis is the method of nonlinear perturbations for structural identification and model reduction. Starting from a detailed mathematical process description both singular and regular structural perturbations are detected. These techniques are then used to give insight into the system structure and where appropriate to eliminate superfluous model equations or reduce them to other forms. This process retains the ability to interpret the reduced order model in terms of the physico-chemical phenomena. Using this model reduction technique it is possible to attribute observable dynamics to particular unit operations within the process. This relationship then highlights the unit operations which must be accurately modelled in order to develop a robust plant model. The technique generates detailed insight into the dynamic structure of the models providing a basis for system re-design and dynamic analysis. The technique is illustrated on the modelling for an evaporator startup. Copyright (C) 1996 Elsevier Science Ltd

From creative ideas to new emerging ventures: the process of identification and exploitation among finnish design entrepreneurs

This study focuses on identification and exploitation processes among Finnish design entrepreneurs (i.e. selfemployed industrial designers). More specifically, this study strives to find out what design entrepreneurs do when they create new ventures, how venture ideas are identified and how entrepreneurial processes are organized to identify and exploit such venture ideas in the given industrial context. Indeed, what does educated and creative individuals do when they decide to create new ventures, where do the venture ideas originally come from, and moreover, how are venture ideas identified and developed into viable business concepts that are introduced on the markets? From an academic perspective: there is a need to increase our understanding of the interaction between the identification and exploitation of emerging ventures, in this and other empirical contexts. Rather than assuming that venture ideas are constant in time, this study examines how emerging ideas are adjusted to enable exploitation in dynamic market settings. It builds on the insights from previous entrepreneurship process research. The interpretations from the theoretical discussion build on the assumption that the subprocesses of identification and exploitation interact, and moreover, they are closely entwined with each other (e.g. McKelvie & Wiklund, 2004, Davidsson, 2005). This explanation challenges the common assumption that entrepreneurs would first identify venture ideas and then exploit them (e.g. Shane, 2003). The assumption is that exploitation influences identification, just as identification influences exploitation. Based on interviews with design entrepreneurs and external actors (e.g. potential customers, suppliers and collaborators), it appears as identification and exploitation of venture ideas are carried out in close interaction between a number of actors, rather than alone by entrepreneurs. Due to their available resources, design entrepreneurs have a desire to focus on identification related activities and to find external actors that take care of exploitation related activities. The involvement of external actors may have a direct impact on decisionmaking and various activities along the processes of identification and exploitation, which is something that previous research does not particularly emphasize. For instance, Bhave (1994) suggests both operative and strategic feedback from the market, but does not explain how external parties are actually involved in the decisionmaking, and in carrying out various activities along the entrepreneurial process.

Fast identification algorithms for Gaussian process model

A class identification algorithms is introduced for Gaussian process(GP)models.The fundamental approach is to propose a new kernel function which leads to a covariance matrix with low rank,a property that is consequently exploited for computational efficiency for both model parameter estimation and model predictions.The objective of either maximizing the marginal likelihood or the Kullback–Leibler (K–L) divergence between the estimated output probability density function(pdf)and the true pdf has been used as respective cost functions.For each cost function,an efficient coordinate descent algorithm is proposed to estimate the kernel parameters using a one dimensional derivative free search, and noise variance using a fast gradient descent algorithm. Numerical examples are included to demonstrate the effectiveness of the new identification approaches.

Identification and characterization of antigenic proteins potentially expressed during the infectious process of Paracoccidioides brasiliensis

Paracoccidioides brasiliensis causes paracoccidioidomycosis (PCM), a systemic mycosis presenting clinical manifestations ranging from mild to severe forms. A P. brasiliensis cDNA expression library was produced and screened with pooled sera from PCM patients adsorbed against antigens derived from in vitro-grown P. brasiliensis yeast cells. Sequencing DNA inserts from clones reactive with PCM patients sera indicated 35 open reading frames presenting homology to genes involved in metabolic pathways, transport, among other predicted functions. The complete cDNAs encoding aromatic-L-amino-acid decarboxylase (Pbddc), lumazine synthase (Pbls) and a homologue of the high affinity copper transporter (Pbctr3) were obtained. Recombinant proteins PbDDC and PbLS were obtained; a peptide was synthesized for PbCTR3. The proteins and the synthetic peptide were recognized by sera of patients with confirmed PCM and not by sera of healthy patients. Using the in vivo-induced antigen technology (IVIAT), we identified immunogenic proteins expressed at high levels during infection. Quantitative real time RTPCR demonstrated high transcript levels of Pbddc, Pbls and Pbctr3 in yeast cells infecting macrophages. Transcripts in yeast cells derived from spleen and liver of infected mice were also measured by qRT-PCR. Our results suggest a putative role for the immunogenic proteins in the infectious process of P. brasiliensis. (C) 2009 Elsevier Masson SAS. All rights reserved.
