Virtsa-avannepotilaan ohjauksen rungon suunnittelu

Potilaan ohjaus korostuu nykypäivänä entistä enemmän. Potilaat tarvitsevat tutkimusten mukaan enemmän ohjausta liittyen sairauteen ja sen tuomiin fyysisiin, psyykkisiin ja sosiaalisiin muutoksiin. Lyhentyneet sairaalassaoloajat luovat paineita potilaan ohjaukselle, ja potilaiden tulee oppia hallitsemaan sairauden tuomat muutokset melko lyhyessä ajassa. Meilahden sairaalan osasto 132U halusi kehittää yhteneväiset ohjeet virtsa-avannepotilaan ohjaukseen, jotta potilaan ohjaus ja opetus olisi laadukasta ja tätä kautta paranisivat myös potilaan itsehoitokyky ja elämänlaatu. Tarkoituksenamme oli luoda virtsa-avannepotilaan ohjauksen runko yhdessä Meilahden sairaalan osasto 132U:n kehittämishankkeen kanssa. Opinnäytetyömme käsittelee virtsa-avanne potilaan ohjauksen laadun parantamista. Virtsa-avanne joudutaan tekemään yleensä syövän, trauman, synnynnäisen epämuodostuman tai virtsarakon toimintahäiriön vuoksi. Yleisin osastolla 132U tehtävä virtsa-avanne on Brickerin diversio, jossa avanne tulee vatsanpeitteiden läpi iholle ja virtsa kerääntyy iholle kiinnitettävään avannepussiin. Yleisin syy virtsa-avanteen tekoon osastolla 132U on virtsarakon syöpä. Opinnäytetyömme aihe lähti työelämän tarpeista saada tietoa virtsa-avannepotilaan ohjauksesta. Meilahden sairaalan osastolla 132U alkoi vuonna 2006 virtsa-avannepotilaan ohjaus osastolla - kehittämishanke, johon osallistuimme tekemällä kirjallisuuskatsauksen kehittämishankkeen käyttöön. Kehittämishankkeen tavoitteena on, että virtsa-avannepotilaan saama ohjaus ja opetus on laadukasta, jolloin potilaan elämänlaatu ja itsehoitokyky paranee. Kirjallisuuskatsauksen pohjalta tehtiin ohjausrunko, jonka avulla hoitajat pystyvät määrätietoisesti ohjaamaan virtsa-avannepotilasta. Ohjausrungon keskeisiksi alueiksi muodostuivat sairaus ja sen hoito, potilaan psykososiaaliset muutokset, potilaan rooli, kuntoutuminen, seksuaalisuus, käytännön asiat ja omaisen ohjaustarpeet. Kirjallisuuskatsauksessa tarkastelimme myös potilaiden parhaina pitämiä ohjausmentelmiä sekä potilaiden ajatuksia parhaasta ohjauksen ajankohdasta. Tekemämme kirjallisuuskatsaus loi pohjan projektiryhmän tekemälle ohjauskaavakkeelle. Ohjauskaavake otettiin testikäyttöön osastolla helmikuussa 2007, jonka jälkeen sitä muokataan hoitajilta tulleiden ehdotusten mukaan. Toivomme ohjauskaavion tulevan vakituiseen käyttöön osastolla ja näin parantamaan potilaan saaman ohjauksen laatua.

An Illustrated Guide for Monitoring and Protecting Bridge Waterways Against Scour - Project TR-515 - Final Report, March 2006

This report is a well illustrated and practical Guide intended to aid engineers and engineering technicians in monitoring, maintaining, and protecting bridge waterways so as to mitigate or prevent scour from adversely affecting the structural performance of bridge abutments, piers, and approach road embankments. Described and illustrated here are the scour processes affecting the stability of these components of bridge waterways. Also described and illustrated are methods for monitoring waterways, and the various methods for repairing scour damage and protecting bridge waterways against scour. The Guide focuses on smaller bridges, especially those in Iowa. Scour processes at small bridges are complicated by the close proximity of abutments, piers, and waterway banks, such that scour processes interact in ways difficult to predict and for which reliable design relationships do not exist. Additionally, blockage by woody debris or by ice, along with changes in approach channel alignment, can have greater effects on pier and abutment scour for smaller bridges. These considerations tend to cause greater reliance on monitoring for smaller bridges. The Guide is intended to augment and support, as a source of information, existing procedures for monitoring bridge waterways. It also may prompt some adjustments of existing forms and reports used for bridge monitoring. In accord with increasing emphasis on effective management of public facilities like bridges, the Guide ventures to include an example report format for quantitative risk assessment applied to bridge waterways. Quantitative risk assessment is useful when many bridges have to be evaluated for scour risk and damage, and priorities need to be determined for repair and protection work. Such risk assessment aids comparison of bridges at risk. It is expected that bridge inspectors will implement the Guide as a concise, handy reference available back at the office. The Guide also likely may be implemented as an educational primer for new inspectors who have yet to become acquainted with waterway scour. Additionally, the Guide may be implemented as a part of process to check whether existing bridge-inspection forms or reports adequately encompass bridge-waterway scour.

Procompetitive Losses from Trade

We argue that the procompetitive effect of international trade may bring about significant welfare costs that have not been recognized. We formulate a stylized general equilibrium model with a continuum of imperfectly competitive industries to show that, under plausible conditions, a trade-induced increase in competition can actually amplify monopoly distortions. This happens because trade, while lowering the average level of market power, may increase its cross-sectoral dispersion. Using data on US industries, we document a dramatic increase in the dispersion of market power overtime. We also show evidence that trade might be responsible for it and provide some quantifications of the induced welfare cost. Our results suggest that, to avoid some unpleasant effects of globalization, trade integration should be accompanied by procompetitive reforms (i.e., deregulation) in the nontraded sectors.

On Globalization and the Growth of Governments

This paper investigates the relationship between trade openness and the size of government, both theoretically and empirically. We show that openness can increase the size of governments through two channels: (1) a terms of trade externality, whereby trade lowers the domestic cost of taxation and (2) the demand for insurance, whereby trade raises risk and public transfers. We provide a unified framework for studying and testing these two mechanisms. First, we show how their relative strength depends on a key parameter, the elasticity of substitution between domestic and foreign goods. Second, while the terms of trade externality leads to inefficiently large governments, the increase in public spending due to the demand for insurance is optimal. We show that large volumes of trade may result in welfare losses if the terms of trade externality is strong enough while small volumes of trade are always beneficial. Third, we provide new evidence on the positive association between openness and the size of government and test whether it is consistent with the terms of trade externality or the demand for insurance. Our findings suggest that the positive relationship is remarkably robust and that the terms of trade externality may be the driving force behind it, thus raising warnings that globalization may have led to inefficiently large governments.

The skill bias of world trade

Under plausible assumptions about preferences and technology, the model in this papersuggests that the entire volume of world trade matters for wage inequality. Therefore,trade integration, even among identical countries, is likely to increase the skill premium.Further, we argue that empirical evidence of a falling relative price of skill-intensive goods can be reconciled with the fast growth of world trade and that the intersectoral mobility of capital exacerbates the effect of trade on inequality. We provide new empirical evidence in support of our results and a quantitative assessment of the skill bias of world trade.

EWS-FLI-1 modulates miRNA145 and SOX2 expression to initiate mesenchymal stem cell reprogramming toward Ewing sarcoma cancer stem cells.

Cancer stem cells (CSCs) display plasticity and self-renewal properties reminiscent of normal tissue stem cells, but the events responsible for their emergence remain obscure. We recently identified CSCs in Ewing sarcoma family tumors (ESFTs) and showed that they retain mesenchymal stem cell (MSC) plasticity. In the present study, we addressed the mechanisms that underlie ESFT CSC development. We show that the EWS-FLI-1 fusion gene, associated with 85%-90% of ESFTs and believed to initiate their pathogenesis, induces expression of the embryonic stem cell (ESC) genes OCT4, SOX2, and NANOG in human pediatric MSCs (hpMSCs) but not in their adult counterparts. Moreover, under appropriate culture conditions, hpMSCs expressing EWS-FLI-1 generate a cell subpopulation displaying ESFT CSC features in vitro. We further demonstrate that induction of the ESFT CSC phenotype is the result of the combined effect of EWS-FLI-1 on its target gene expression and repression of microRNA-145 (miRNA145) promoter activity. Finally, we provide evidence that EWS-FLI-1 and miRNA-145 function in a mutually repressive feedback loop and identify their common target gene, SOX2, in addition to miRNA145 itself, as key players in ESFT cell differentiation and tumorigenicity. Our observations provide insight for the first time into the mechanisms whereby a single oncogene can reprogram primary cells to display a CSC phenotype.

Forme e funzioni del coro tragico in Italia (1524-1824)

Ce travail n'a pas pour but d'établir une histoire du choeur tragique pour ainsi dire 'd'anthologie', mais bien plutôt de tracer un parcours sélectif et dynamique, en suivant l'évolution de ses formes et de ses fonctions dans la tragédie italienne, à partir du début du XVIe siècle jusqu' à la production alfiérienne et au retour du choeur dans le théâtre de Manzoni ; à cela s'ajoute un exercice en dehors du genre dramatique tel que le Dialogo di Federico Ruysch e delle sue mummie dans les Operette morali di Giacomo Leopardi. Dans la première partie - la plus ample et complexe, portant sur l'emploi du choeur dans la tragédie de la Renaissance - on essaye de cerner le contexte qui favorise la persistance d'un espace choral en examinant plusieurs commentaires de la Poétique aristotélicienne, et des essais de théorie dramaturgique comme Della poesia rappresentativa de Angelo Ingegneri, ou le Discorso intorno al comporre de Giambattista Giraldi Cinzio. À côté de la discussion sur le rôle du choeur on envisage aussi le profil formel des sections chorales, en s'appuyant sur l'analyse métrique, dans le cadre plus général du 'petrarchismo metrico', et en particulier de la réception de la chanson pétrarquesque. Interroger la présence de trois constantes thématiques - par exemple la forme de l'hymne à Éros - signifie en suite relever l'importance de Sophocle pour le théâtre de la Renaissance dans la perspective du choeur. Cette première section est complétée par un chapitre entièrement consacré à Torquato Tasso et à son Re Torrismondo, qui présente un troisième chant choral de grande épaisseur philosophique, central dans l'économie du drame et analysé ici à travers un exercice de lecture qui utilise à la fois les instruments de la stylistique, de l'intertextualité, et de l'intratextualité concernant l'entier corpus poétique et philosophique tassien, de ses Rime aux Dialoghi. La deuxième section, qui commence par une exploration théorique de la question du choeur, conduite par exemple sur les textes de Paolo Beni e Tommaso Campanella, a pour cible principale de expliquer comment le choeur assume le rôle d'un vrai 'personnage collectif' dans le théâtre de Federico Della Valle : un choeur bien installé dans l'action tragique, mais conservant au même temps les qualités lyriques et philosophiques d'un chant riche de mémoire culturelle et intertextuelle, de la Phaedra de Sénèque à la Commedia dantesque dans la Reina di Scozia, centre principal de l'analyse et coeur du catholicisme contreréformiste dellavallien. Dans la troisième partie le discours se concentre sur les formes de la métamorphose, pour ainsi dire, du choeur : par exemple la figure du confident, conçu comme un substitut du groupe choral dans les discussions des théoriciens et des auteurs français - voir Corneille, D'Aubignac, Dacier - et italiens, de Riccoboni à Calepio et Maffei. Cependant dans cette section il est surtout question de la définition de l'aria mélodramatique compris comme le 'nouveau choeur' des Modernes, formulée par Ranieri Calzabigi et par Metastasio. Il s'agit donc ici de mettre en relation l'élaboration théorique contenue dans la Dissertazione de Calzabigi et dans l'Estratto de l'Arte poetica de Metastasio avec le premier et unique essai tragique de jeunesse de ce dernier, le Giustino, et le livret de son Artaserse. On essaye de montrer le profond lien entre l'aria et l'action dramatique : donc c'est le dramma musicale qui est capable d'accueillir la seule forme de choeur - l'aria - encore possible dans le théâtre moderne, tandis que le choeur proprement tragique est désormais considéré inutilisable et pour ainsi dire hors-contexte (sans toutefois oublier qu'à la fin du siècle Vittorio Alfieri essayait de ne pas renoncer au choeur dans sa traduction des Perses d'Eschyle ; et surtout dans un essai tragique comme l'Alceste seconda ou dans sa tramelogedia, l'Abele). Comme conclusion une section contenant des remarques qui voudrait juste indiquer trois possibles directions de recherche ultérieure : une comparaison entre Manzoni et Leopardi - dans la perspective de leur intérêt pour le choeur et de la différence entre le sujet lyrique manzonien et celui léopardien ; une incursion dans le livret du mélodrame verdien, afin de comprendre la fonction du choeur manzonien et sa persistance dans le texte pour l'opéra ; et enfin quelque note sur la réception du choeur manzonien et du Coro di morti léopardien dans le XXe siècle, en assumant comme point d'observation la poésie de Carlo Michelstaedter, Andrea Zanzotto et Franco Fortini. Il lavoro non intende tracciare una storia 'da manuale' del coro tragico, ma piuttosto indicare un percorso selettivo e dinamico, seguendo l'evoluzione delle sue forme e delle sue funzioni nella tragedia italiana, a partire dall'inizio del sedicesimo secolo per arrivare alla produzione alfieriana e al ritorno del coro nel teatro di Manzoni; a ciò si aggiunge una prova estranea al genere drammatico come il Dialogo di Federico Ruysch e delle sue mummie nelle Operette morali di Giacomo Leopardi. Nella prima parte - la più ampia e complessa, riguardante l'impiego del coro nella tragedia rinascimentale - si cerca di ricostruire il contesto che favorisce la persistenza dello spazio corale attraverso l'esame di diversi commenti alla Poetica aristotelica, e di alcuni saggi di teoria drammaturgica come Della poesia rappresentativa di Angelo Ingegneri, o il Discorso intorno al comporre di Giambattista Giraldi Cinzio. La discussione sul ruolo del coro è affiancata dall'esame del profilo formale delle sezioni corali, grazie a un'indagine metrica nel quadro del più ampio petrarchismo metrico cinquecentesco, e in particolare nel quadro della ricezione della formacanzone petrarchesca. Interrogare la presenza di tre costanti tematiche - per esempio la forma dell'inno a Eros - significherà in seguito rilevare l'importanza di Sofocle per il teatro rinascimentale anche nella prospettiva angolata del coro. Questa prima sezione è completata da un capitolo interamente dedicato a Torquato Tasso e al suo Re Torrismondo, che presenta un terzo canto corale di grande spessore stilistico e filosofico, centrale nell'economia del dramma e analizzato qui attraverso un esercizio di lettura che si serve degli strumenti della stilistica e dell'intertestualità, oltre che del rapporto intratestuale fra i vari luoghi del corpus tassiano, dalle Rime ai suoi Dialoghi. La seconda sezione, che si avvia con un'esplorazione teorica della questione del coro nel Seicento - condotta per esempio sui testi di Paolo Beni e Tommaso Campanella - ha per fulcro la descrizione di un coro quale 'personaggio collettivo' nelle tragedie di Federico Della Valle: un coro ben inserito nell'azione tragica, ma che conserva allo stesso tempo le qualità liriche e filosofiche di un canto ricco di memoria culturale e intertestuale, dalla Fedra di Seneca alla Commedia dantesca, nella sua Reina di Scozia, centro dell'analisi e cardine del cattolicesimo controriformista dellavalliano. Nella terza sezione il discorso si concentra sulle forme della metamorfosi, per così dire, del coro: per esempio la figura del confidente, interpretato come un sostituto del gruppo corale nelle discussioni di teorici e autori francesi - Corneille, D'Aubignac, Dacier - e italiani, da Riccoboni a Calepio e Maffei. Ma qui ci si rivolge anzitutto alla definizione dell'aria melodrammatica, sentita quale 'nuovo coro' dei Moderni da Ranieri Calzabigi e Pietro Metastasio. Si tratterà dunque di mettere in relazione l'elaborazione teorica svolta nella Dissertazione di Calzabigi e nell'Estratto dell'arte poetica di Metastasio con il primo e unico - e giovanile - tentativo tragico di quest'ultimo, il Giustino, e con il libretto del suo Artaserse. L'intenzione è quella di mostrare il profondo legame tra l'aria e l'azione drammatica: è perciò il dramma musicale che è capace di accogliere la sola forma di coro - l'aria - ancora possibile nel teatro moderno, mentre il vero e proprio coro tragico si rassegna ormai a essere considerato inutile e per così dire fuori contesto (senza dimenticare, tuttavia, che al chiudersi del secolo Vittorio Alfieri tentava di non rinunciare al coro nella sua traduzione dei Persiani di Eschilo; e soprattutto in un tentativo tragico come la sua Alceste seconda o nella tramelogedia Abele). In conclusione una più veloce sezione che vorrebbe semplicemente indicare qualche altra possibile direzione di ricerca: un confronto fra Manzoni e Leopardi - nella prospettiva del coro interesse per il coro, e della differenza fra il soggetto lirico manzoniano e quello leopardiano; un'incursione nel libretto del melodramma verdiano, per misurarvi la funzione del coro manzoniano e la sua persistenza nel testo operistico; e infine qualche appunto sulla ricezione del coro manzoniano e del Coro di morti di Leopardi nel Novecento, assumendo quale punto d'osservazione la poesia di Carlo Michelstaedter, Andrea Zanzotto e Franco Fortini.

Trade, migration and regional unemployment

We formulate a dynamic core-periphery model with frictions in the job matching process to study the interplay between trade costs, migration and regional unemploymentin the short- and long-run. We find that the spatial distribution of unemployment mirrors (inversely) the distribution of economic activities. Further, we highlight a contrast between the short-run and the long-run effects of trade-induced migration on regional unemployment. In particular, an inßow of immigrants from the periphery into the core reduces the unemployment gap in the short-run, but exacerbates unemployment disparities in the long-run.

Trade, markup heterogeneity and misallocations

We argue that the procompetitive effect of international trade may bring about significant welfare costs that have not been recognized. We formulate a stylized general equilibrium model with a continuum of imperfectly competitive industries to show that, under plausible conditions, a trade-induced increase in competition can actually amplify monopoly distortions. This happens because trade, while lowering the average level of market power, may increase its cross-sectoral dispersion. Using data on US industries, we document a dramatic increase in the dispersion of market power overtime. We also show evidence thattrade might be responsible for it and provide some quantifications of the induced welfare cost. Our results suggest that, to avoid some unpleasant effects of globalization, trade integration should be accompanied by procompetitive reforms (i.e., deregulation) in the nontraded sectors.

Openness, government size and the terms of trade

This paper investigates the relationship between trade openness and the size of government, both theoretically and empirically. We show that openness can increase the size of governments through two channels: (1) a terms of trade externality, whereby trade lowers the domestic cost of taxation and (2) the demand for insurance, whereby trade raises risk and public transfers. We provide a unified framework for studying and testing these two mechanisms. First, we show how their relative strength depends on a key parameter, the elasticity of substitution between domestic and foreign goods. Second, while the terms of trade externality leads to inefficiently large governments, the increase in public spending due to the demand for insurance is optimal. We show that large volumes of trade may result in welfare losses if the terms of trade externality is strong enough while small volumes of trade are always beneficial. Third, we provide new evidence on the positive association between openness and the size of government and test whether it is consistent with the terms of trade externality or the demand for insurance. Our findings suggest that the positive relationship is remarkably robust and that the terms of trade externality may be the driving force behind it, thus raising warnings that globalization may have led to inefficiently large governments.

Increasing returns, imperfect competition and factor prices

We show how, in general equilibrium models featuring increasing returns, imperfectcompetition and endogenous markups, changes in the scale of economic activity affectincome distribution across factors. Whenever final goods are gross-substitutes (gross-complements), a scale expansion raises (lowers) the relative reward of the scarce factoror the factor used intensively in the sector characterized by a higher degree of product differentiation and higher fixed costs. Under very reasonable hypothesis, our theory suggests that scale is skill-biased. This result provides a microfoundation for the secular increase in the relative demand for skilled labor. Moreover, it constitutes an important link among major explanations for the rise in wage inequality: skill-biased technical change, capital-skill complementarities and international trade. We provide new evidence on the mechanism underlying the skill bias of scale.
