Viikon albumi -haastattelu osana YleX-kanavan ohjelmatarjontaa

Nuorille suunnatut lähetysvirtaradioasemat käyvät Suomessa koko ajan tiukempaa taistelua kuuntelijoidensa huomiosta. Kuuntelijalukuja tarkastellaan miltei viikoittain ja kuuntelijoille tarjottavaa tuotetta pyritään kilpailun koventuessa koko ajan kehittämään. Yleisradiossa tapahtui viimeksi kanavauudistus vuonna 2003, jonka seurauksena Radiomafia -kanava sai uuden nimen YleX. Uudistuksessa radiokanavan kohdeyleisö tarkennettiin uudelleen ja kanavalla siirryttiin soittolistapohjaiseen radion tekemiseen, jossa kanavan musiikkia soitetaan etukäteen laaditulta soittolistalta. Kanavauudistusta kritisoitiin mediassa ja arkipuheessa, vaikka YleX -kanavan viikkokuulijamäärät lähtivät nousuun. Vieläkin YleX:n musiikkitarjontaa arvostellaan yksipuoliseksi ja samalla myös kanavan ohjelmat ovat joutuneet kritiikin kohteeksi. Opinnäytetyöni käsittelee viihdeartistihaastattelun tekemistä YleX-radiokanavalla. Työssäni YleX-kanavalla olen tehnyt viikoittaista viihdeartistihaastattelua, joka tunnetaan nimellä Viikon Albumi -haastattelu. Tämä haastattelu on osa arkipäiväistä YleX Tänään-ohjelmaa, missä sitä lähetetään maanantaisin kello 11.10. Omia haastatteluja reflektoimalla selvitin haastattelijan näkökulmasta, minkälaisin menetelmin nykyaikaisessa nopeatempoisessa lähetysvirtaradiossa syntyy mielenkiintoinen ja syvällinen viihdeartisti-haastattelu. Kuinka lähelle laadukkaan viihdehaastattelun tavoitteita on mahdollista päästä 15 minuutin Viikon Albumi -haastattelun aikana? Työssäni keskityn etenkin YleX:n haastatteluiden viihteelliseen luonteeseen ja nimenomaan viihdeartistin haastattelemiseen, jota on alan kirjallisuudessa käsitelty melko vähän. Viihdyttävän ja hauskan viihdeartistihaastattelun tekeminen on vaikea haastattelumuoto, jonka tekemistä pyrin valottamaan omien töideni avulla. Toivon, että työstäni on jatkossa hyötyä myös muille samankaltaisissa haastattelutilanteissa.

Explicit ruin formulas for models with dependence among risks

We show that a simple mixing idea allows one to establish a number of explicit formulas for ruin probabilities and related quantities in collective risk models with dependence among claim sizes and among claim inter-occurrence times. Examples include compound Poisson risk models with completely monotone marginal claim size distributions that are dependent according to Archimedean survival copulas as well as renewal risk models with dependent inter-occurrence times.

The Economic Effects of Christian Moralities

This article examines the different influences that Catholicism and Protestantism exert on economically relevant values. It argues that Catholic theology and practice facilitate personal transactions while Protestantism favors values and types of moral and legal enforcement better adapted for impersonal trade. Protestantism may thus be more conducive to economic growth through anonymous exchange while Catholicism may provide better support for personal contracting. Several components of this hypothesis are confirmed using statistical models with data from the 1998 ISSP international survey on religion. These show that Protestants are more trusting of anonymous counter parties, develop more reliable institutions for legal enforcement and are more willing to spend resources on monitoring and punishing other members of the community. Catholicism is more protective of the family and small-group relationships, and provides more tolerant and less motivating beliefs. Relatively smaller and less consistent differences appear in terms of worldly personal success and incentives.

Drama i espectacle operístic : la dialèctica entre espai i temps en el Parsifal de Herheim i el ritus com a obra d’art del futur

Parsifal és, segons la manera en què es mire, l’excepció dins el llistat de drames musicals wagnerians pel tractament sense precedents que fa de motius catòlics en un lloc i un moment com la recentment unificada Alemanya, on la construcció de la identitat nacional passava per un model social i cultural concret i, per tant, també religiós. Però una òptica diferent ens pot apropar a una ingent quantitat de paral·lelismes entre el model artístic expressat per Wagner en els seus escrits teòrics de joventut i alguns dels elements estètics i ideològics de la seua darrera obra. L’espectacle operístic en l’actualitat continua sent fruit de la societat en què es gesta i per això Stefan Herheim utilitza una visió diacrònica de la recepció d’aquesta obra wagneriana com a un dels motius principals sobre els quals construirà una dramatúrgia densa i meditada en què es durà a terme fins a les seues últimes conseqüències una revisió en clau contemporània del concepte d’obra d’art del futur.

Functional role of Notch signaling in the developing and postnatal heart

In the developing heart, Notch signaling plays an essential role in several key developmental processes, such as epithelial-to-mesenchymal transition and myocyte proliferation and differentiation. The importance of Notch in cardiac development has been demonstrated in knockout mice carrying null mutations in genes encoding components of the Notch pathway. Furthermore, humans with inactivating mutations in the Notch ligand Jagged1 suffer from Alagille syndrome, a condition characterized by several cardiac defects. Notch1 receptor haploinsufficiency has also been involved in aortic valve disease in humans. In addition, accumulating evidence indicates that Notch may also regulate homeostasis in the adult heart. Notch may protect the heart from an excessive and detrimental hypertrophic response and increase cardiomyocyte survival. Emerging evidence also suggests that Notch could be important for cardiac tissue renewal by controlling the maintenance and commitment of a cardiac stem cell compartment.

Oligopotent stem cells are distributed throughout the mammalian ocular surface.

The integrity of the cornea, the most anterior part of the eye, is indispensable for vision. Forty-five million individuals worldwide are bilaterally blind and another 135 million have severely impaired vision in both eyes because of loss of corneal transparency; treatments range from local medications to corneal transplants, and more recently to stem cell therapy. The corneal epithelium is a squamous epithelium that is constantly renewing, with a vertical turnover of 7 to 14 days in many mammals. Identification of slow cycling cells (label-retaining cells) in the limbus of the mouse has led to the notion that the limbus is the niche for the stem cells responsible for the long-term renewal of the cornea; hence, the corneal epithelium is supposedly renewed by cells generated at and migrating from the limbus, in marked opposition to other squamous epithelia in which each resident stem cell has in charge a limited area of epithelium. Here we show that the corneal epithelium of the mouse can be serially transplanted, is self-maintained and contains oligopotent stem cells with the capacity to generate goblet cells if provided with a conjunctival environment. Furthermore, the entire ocular surface of the pig, including the cornea, contains oligopotent stem cells (holoclones) with the capacity to generate individual colonies of corneal and conjunctival cells. Therefore, the limbus is not the only niche for corneal stem cells and corneal renewal is not different from other squamous epithelia. We propose a model that unifies our observations with the literature and explains why the limbal region is enriched in stem cells.

Discursos de gènere, nacionalisme i respostes col•lectives de les dones a Catalunya i Irlanda

El projecte realitzat se situa en el marc de la història contemporània, i s’ha centrat en primer lloc, en l’anàlisi, des d’una perspectiva comparativa, del desenvolupament dels discursos de gènere a Catalunya durant la Dictadura Franquista i a la Irlanda postcolonial. Mitjançant l’anàlisi del discurs, s’han estudiat els models de feminitat imposats pel Franquisme i les seves bases ideològiques com són el valors catòlics i l’antindividualisme. En el cas irlandès, s’ha analitzat com, a través de determinades institucions gestionades per l’Església Catòlica, es controlaven aquelles dones que es desviaven del model de gènere que propugnava l’Estat Irlandès, molt similar al proposat pel Franquisme i també basat en els catolicisme. De la mateix manera, s’ha estudiat com el feminisme Català i irlandès dels anys 1970 i 1980 van contrarestar aquests models de gènere imposats, a través de l’anàlisi d’un conjunt d’expressions culturals produïdes per ambdós moviments feministes. La perspectiva comparativa del projecte ha permès: El coneixement dels mecanismes culturals de repressió de les dones així com la seva institucionalització. Revelant els paral•lelismes pel que fa a les polítiques de gènere entre els dos casos estudiats malgrat diferències significatives entre els dos contextos (Catalunya es troba sota una dictadura, Irlanda és un Estat democràtic). La importància de l’agència de les dones i les seves diverses estratègies de resistència, especialment a través d’expressions culturals més efímeres o considerades frívoles que, malgrat el poc reconeixement que han obtingut, són molt eficaces en la deconstrucció de discursos de gènere repressius envers les dones. Ha posat de manifest, també, la importància de l’experiència i les pràctiques personals i íntimes com a pràctiques de resistència. Així mateix, ha visibilitzat les dinàmiques pròpies de moviments feministes.

Lane Closure Policy Development, Enforcement, and Exceptions: A Survey of Seven State Transportation Agencies, February 2007

Traffic volume increases and an aging infrastructure create the need for reconstruction, rehabilitation, and maintenance of existing facilities. As more motorists feel that delays should be minimal during highway renewal projects, lane closures that reduce capacity through the work zone should not create unreasonable delays. In order to facilitate the determination of when a lane closure is permitted during the day, some state transportation agencies (STAs) have developed lane closure policies, or strategies, that they use as guidance in determining daily permitted lane closure times. Permitted lane closure times define what times of the day, week, or season a lane closure is allowed on a facility and at a specific location or segment. This research addresses the lane closure policies of several STAs that were reputed to have good lane closures policies or strategies and that were selected by the project advisory committee for further research.

Appartenances en fête: entre l'ordinaire et le spectaculaire

Résumé Alors que les pratiques religieuses régulières diminuent et que les groupes religieux majoritaires perdent des membres formellement enregistrés, une évènementisation de l'appartenance religieuse peut être observée depuis environ deux décennies. Dans un premier exemple, l'auteure montre que le réseau transnational de la confrérie soufie des Mourides resserre les liens entre adeptes dans un contexte migratoire qui tend à fragiliser les relations sociales. La confrérie y fait face à travers une spectacularisation de la pratique religieuse, occupant l'espace public à Harlem ou, dans une moindre mesure, à Paris. Le second exemple traite du pèlerinage aux Saintes et Saints d'Afrique dans la ville valaisanne de Saint Maurice. Ce dernier fut inventé par l'Église catholique suisse afin d'attirer des migrants africains, mais aussi afin de redynamiser une pratique religieuse ordinaire en perte de vitesse. L'évènement a lieu en même temps que le pèlerinage de Namugongo en Ouganda, réunissant plus d'un demi-million de personnes. Les communautés évènementielles ainsi créées sont-elles durables ou plutôt liquides ? Abstract While regular religious practice is decreasing and the major religious groups are losing formally registered members, a 'spectacularization' of religious belonging can be observed over the last two decades. The author presents two examples to support this argument. In the first, the transnational network of the Murids, a Sufi brotherhood, has tried to reinforce the relations between its members, which become fragile during migration. The brotherhood occupies a public space in Harlem, and, to a lesser extent, in Paris, in a spectacularization of religious belonging, in order to remain attractive to migrants. The second example deals with the pilgrimage dedicated to African Saints in the Swiss town of Saint Maurice. This event was invented by the missionary service of the Swiss Catholic Church in order to attract African migrants, but also in order to make ordinary religious practice more appealing. The event takes place at the same time as the Ugandan pilgrimage of Namugongo, which assembles more than half a million people. However, are these 'event communities' sustainable or ephemeral?

Quarterly Report of the Building Project for the Motor Vehicle Division

Pursuant to Section 1 of House File 466 of the 81st General Assembly, the Iowa Department of Transportation is required to make quarterly reports to the Legislative Council regarding the progress of the building project for the Motor Vehicle Division. During the quarter ending June 30, 2007, the project was delayed by two weeks. The Motor Vehicle Division moved into the new Ankeny facility on June 22 and was operational Monday, June 25. The driver's license stations reopened as scheduled Tuesday, June 26, at the Ankeny facility as well as the Oliver Plaza renewal location.

Banks and development: Jewish communities in the Italian Renaissance and current economic performance

Are differences in local banking development long-lasting? Do they affect long-term economic performance?I answer these questions by relying on an historical development that occurred in Italian cities during the 15thcentury. A sudden change in the Catholic doctrine had driven the Jews toward money lending. Cities thatwere hosting Jewish communities developed complex banking institutions for two reasons: first, the Jews werethe only people in Italy who were allowed to lend for a profit and, second, the Franciscan reaction to Jewishusury led to the creation of charity lending institutions, the Monti di Pietà, that have survived until today andhave become the basis of the Italian banking system. Using Jewish demography in 1500 as an instrument, Iprovide evidence of (1) an extraordinary persistence in the level of banking development across Italian cities (2)large effects of current local banking development on per-capita income. Additional firm-level analyses suggestthat well-functioning local banks exert large effects on aggregate productivity by reallocating resources towardmore efficient firms. I exploit the expulsion of the Jews from the Spanish territories in Italy in 1541 to arguethat my results are not driven by omitted institutional, cultural and geographical characteristics. In particular,I show that, in Central Italy, the difference in current income between cities that hosted Jewish communitiesand cities that did not exists only in those regions that were not Spanish territories in the 16th century.

Gene expression profiling of human glioblastomas for the identification of predictive factors and characterisation of molecular mechanism implicated in response to therapy and outcome

ABSTRACT Poor outcome for glioblastoma patients is largely due to resistance to chemoradiation therapy. While epigenetic inactivation of MGMT mediated DNA repair is highly predictive for benefit from the alkylating agent therapy Temozolomide, additional mechanisms for resistance associated with molecular alterations exist. Furthermore, new concepts in cancer suggest that resistance to treatment may be linked to cancer stem cells that escape therapy and act as source for tumour recurrence. We determined gene expression signatures associated with outcome in glioblastoma patients enrolled in a phase II and phase III clinical trial establishing the new combination therapy of radiation plus concomitant and adjuvant Temozolomide. Correlating stable gene clusters emerging from unsupervised analysis with survival of 42 treated patients identified a number of biological processes associated with outcome. Most prominent, a gene cluster dominated by HOX genes and comprising PROM1, was associated with resistance. PROM1 encodes CD133, a marker for a subpopulation of tumour cells enriched for glioblastoma stem- like cells. The core of this correlated HOX cluster was comprised in the top genes of a "self-renewal signature" defined in a mouse model for MLL-AF9 initiated leukaemia. The association of the HOX gene cluster with tumour resistance was confirmed in two external data sets of 146 malignant glioma As additional resistance factors we identified over-expression of the epidermal growth factor receptor gene, EGFR, while increased gene expression related to biological features of tumour host interaction, including markers for tumour vascular and cell adhesion, and innate immune response, were associated with better outcome. The "self-renewal" signature associated with resistance to the new combination chemoradiation therapy provides first clinical evidence that glioma stem like cells may implicated in resistance in a uniformly treated cohort of glioblastoma patients. This study underlines the need to target the tumour stem cell compartment, and provides some testable hypothesis for biological mechanisms relevant for malignant behaviour of glioblastoma that may be targeted in new treatment approaches. Résumé Le glioblastome, tumeur cérébrale primaire maligne la plus fréquente, est connue pour son mauvais pronostique. Des avancées chimiothérapeutiques récentes avec des agents alkylants comme le témozolomide (TMZ), ont permis une amélioration notable dans la survie de certains patients. Les bénéficiaires ont la caractéristique commune de présenter une particularité génétique, la methylation du MGMT (methylguanine methyltransferase). Néanmoins, d'autres mécanismes de résistance en fonction des aberrations moléculaires existent. Nous avons établi les profils d'expressions génétiques des patients traités par irradiation et TMZ dans des études cliniques de phase II et III. En combinant des méthodes non-supervisées et supervisées, de l'étude de la cohorte des patients traités nous avons découvert des groupes de gènes associés à la survie. Un ensemble de gènes contenant les gènes Hox semble lié au mécanisme de résistance au traitement. Récemment, les gènes Hox ont été décrits comme faisant partie d"une signature d'autorenouvellement (self-renewal) des cellules souches cancéreuses de la leucémie. L'autorenouvellement est un processus grâce auquel les cellules souches se maintiennent tout au long de la vie. Cette association à la résistance est confirmée dans deux autres études indépendantes. Un autre facteur de résistance au traitement est la surexpression du gène EGFR. D'autre part, deux groupes de gènes associés à la relation entre hôte-tumeur tels que les marqueurs des vaisseaux tumoraux et de la réponse immunitaire innée s'avèrent avoir un effet positif sur la survie des patients traités. La découverte de la signature d'autorenouvellement comme facteur de résistance à la nouvelle chimio-radiothérapie offre une preuve clinique que les cellules souches cancéreuses sont impliquées dans la résistance au traitement. If est donc logique de penser que le traitement ciblé contre des cellules souches cancéreuses va dans l'avenir permettre des thérapies anticancéreuses plus performantes.

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.

Smad3 signaling is required for satellite cell function and myogenic differentiation of myoblasts.

TGF-β and myostatin are the two most important regulators of muscle growth. Both growth factors have been shown to signal through a Smad3-dependent pathway. However to date, the role of Smad3 in muscle growth and differentiation is not investigated. Here, we demonstrate that Smad3-null mice have decreased muscle mass and pronounced skeletal muscle atrophy. Consistent with this, we also find increased protein ubiquitination and elevated levels of the ubiquitin E3 ligase MuRF1 in muscle tissue isolated from Smad3-null mice. Loss of Smad3 also led to defective satellite cell (SC) functionality. Smad3-null SCs showed reduced propensity for self-renewal, which may lead to a progressive loss of SC number. Indeed, decreased SC number was observed in skeletal muscle from Smad3-null mice showing signs of severe muscle wasting. Further in vitro analysis of primary myoblast cultures identified that Smad3-null myoblasts exhibit impaired proliferation, differentiation and fusion, resulting in the formation of atrophied myotubes. A search for the molecular mechanism revealed that loss of Smad3 results in increased myostatin expression in Smad3-null muscle and myoblasts. Given that myostatin is a negative regulator, we hypothesize that increased myostatin levels are responsible for the atrophic phenotype in Smad3-null mice. Consistent with this theory, inactivation of myostatin in Smad3-null mice rescues the muscle atrophy phenotype.

Leadership in cardiac surgery.

Despite the efficacy of cardiac surgery, less invasive interventions with more uncertain long-term outcomes are increasingly challenging surgery as first-line treatment for several congenital, degenerative and ischemic cardiac diseases. The specialty must evolve if it is to ensure its future relevance. More importantly, it must evolve to ensure that future patients have access to treatments with proven long-term effectiveness. This cannot be achieved without dynamic leadership; however, our contention is that this is not enough. The demands of a modern surgical career and the importance of the task at hand are such that the serendipitous emergence of traditional charismatic leadership cannot be relied upon to deliver necessary change. We advocate systematic analysis and strategic leadership at a local, national and international level in four key areas: Clinical Care, Research, Education and Training, and Stakeholder Engagement. While we anticipate that exceptional individuals will continue to shape the future of our specialty, the creation of robust structures to deliver collective leadership in these key areas is of paramount importance.
