Jacopo Bassano freskomaalarina : Cartiglianon ja Enegon kirkkojen freskot: konteksti, rekonstruktio ja tulkinta

The object of this study is Jacopo Bassano (c. 1510 1592) as a fresco painter and the significance of frescoes in his late production. The research focuses on the only surviving cycle of frescoes of his later years in the Cartigliano parish church, bearing the date 1575. The other cycle studied here was painted for the 16th century parish church of Enego. It contained one of the most extensive fresco decorations executed by Jacopo Bassano together with his eldest son Francesco. However, nothing has survived of the fresco cycle and the ceiling paintings of the church, nor is any visual documentation of them left. Only the small altarpiece attributed to Jacopo Bassano and depicting Saints Justine, Sebastian, Anthony Abbott, and Roch (dated to c. 1555/1560) has been preserved. I have suggested that the frescoes of the Cartigliano parish church should be examined in the interpretational context of the spirituality of the post-Tridentine period. This period frames the historical context for the frescoes and functions as a basis for the iconographical interpretation that I have proposed. I have shown that the iconographic programme of the frescoes in the choir of the Cartigliano parish church has obvious points of contact with the Catholic doctrines reconfirmed by the Council of Trent (1545 1563). I also argue that the fresco cycle and the ceiling paintings of the Enego church should be placed in the same interpretational context as the frescoes of Cartigliano. I present a reconstruction of the frescoes in the choir attributed to Jacopo Bassano and of those on the walls of the nave attributed to his son Francesco Bassano. According to my reconstruction, the frescoes in the choir and nave walls formed a coherent cycle with a unitary iconographic programme which included the 28 paintings with Old Testament subjects in the nave ceiling. The reconstruction includes the dating and the iconography of the fresco programme and its interpretative basis. The reconstruction is based on visitation records and inventories from the 16th and 17th centuries as well as on the oldest relevant literature, namely the descriptions offered by Carlo Ridolfi (1648) and G. B. Verci (1775). I also consider the relationship of the large compositional sketches attributed to Jacopo Bassano and depicting Christological subjects to the lost frescoes in Enego. These studies have been executed with coloured chalks, and many of them are also dated 1568 or 1569 by the painter. I suggest in this study that these large studies in coloured chalks were preparatory drawings for the fresco cycle in Enego, depicting scenes from the life and suffering of Christ. All the subjects of the aforesaid drawings were included in the Enego cycle.

Fernando Pessoan ortonyymi ja heteronyymit modernistis-romanttisena myyttinä

Tutkimuksessani selvitän portugalilaisrunoilija Fernando Pessoan (1888-1935) heteronyymejä ja ortonyymiä modernistis-romanttisena myyttinä. Myytin piirteet paljastuivat Pessoan omia kirjoituksia ja runoja tutkimalla ja käyttämällä apuna Pessoa-tutkimusta. Tutkimusaineistonani ovat Pessoa-ortonyymin Mensagem-runoelma ja ”Autopsykografia”-runo, Álvaro de Campoksen vuonna 1917 Portugal Futurista –lehdessä julkaistu ”Ultimatum”-runomanifesti, Alberto Caeiron ”Guardador de Rebanhos”-runosikermä sekä Ricardo Reisin ”Oodit”-kokonaisuuteen kuuluvat runot: n:ro 59 ”Acima da verdade estão os deuses” (”Totuuden yläpuolella ovat jumalat”, 1914), n:ro 66 ”Olho os campos, Neera” (”Katson peltoja, Neera”, 1917), n:ro 181 ”Amo o que vejo” (”Rakastan sitä mitä näen”, 1934), n:ro 175 ”Estas só. Ninguem o sabe.” (”Olet yksin. Kukaan ei tiedä sitä”, 1933). Tutkimuksessani romanttisen runouden keskeisinä piirteinä pidetään uskoa taiteilijaneroon (geniukseen), mimeettiseen illuusioon (taide tavoittelee ulkoisen todellisuuden toisintamista mahdollisimman autenttisena) ja tekijän ja kokijan eli subjektin ja objektin erottamiseen toisistaan. Käsitänkin modernin runon tutkimuksessani hylänneen monia entisiä käsityksiä ja vastakkainasetteluja muun muassa tekijän ja ulkopuolisen maailman, mielen ja kielen välillä. Näitä moderneja ”rikkomuksia” identifioin ja määrittelen Pessoan heteronyymien runoudessa. Tutkimukseni apukäsitteitä ovat vilpittömyys ja autenttisuus, jotka kuvaavat runoilijan suhdetta itseensä ja muihin ja joita on pohtinut mm. Lionel Trilling teoksessaan Sincerity and authencity. Romanttisessa runoudessa suhde yhteisöön muodostui ensisijaisesti suhteessa omaan itseen, yhtenäiseen minuuteen nojaavan vilpittömyyden kautta, modernissa runoudessa hajanaisuutta ja yksilön suhdetta myös yhteisöön korostavan autenttisuuden avulla. Tutkimuksessani havaitsin, että Pessoa on jo tuotantonsa alusta lähtien kehittänyt tietoisesti modernistis-romanttista myyttiä – päätelmää tukivat niin Pessoan omat kirjoitukset kuin runoanalyysini. Pessoa ennusti ensimmäisen kerran romanttiseen nerotaiteilijaan vertautuvaa ”supra-Camõesia” ”A nova poesia Portuguesa Sociologicamente considerada” –esseessään vuonna 1912. Campoksen ”Ultimatum”-manifestissa puhuja uskoi muutaman useita kymmeniä persoonallisuuksia hallitsevan ”Synteesi-Ihmisen” tai ”supra-Camõesin” ilmestymiseen. ”Synteesi-Ihmisen” oli määrä palauttaa kukoistukseensa lamaantuneessa tilassa ollut Portugalin kirjallisuus uuteen kukoistukseensa. Eräänlaisen perustan koko myytille loi vuotta ennen Pessoan kuolemaa julkaistu Mensagem (suom. Viesti), jossa runoilija esittää saudosistisen ja sebastianistisen perustan. Teixeira de Pascoaesin kehittämä saudosismi näkyy Mensagemissa uskona Portugalin valtion perustajien ja laajentajien – löytöretkeilijöiden – edustamaan voittoisaan lusofoniseen mentaliteettiin, jonka Pessoa asettaa niin kansakunnan, runoilijan kuin ihmisen ihanteeksi. Toinen Mensagemissa esiintyvä myytin rakennusaine on sebastianismi eli usko kuningas Sebastianin (1554-1578) paluuseen. ”Synteesi-Ihminen”/”supra-Camões” oli reinkarnoitunut Sebastian, jonka piti palauttaa kansa ja kulttuuri kukoistukseensa lusofonisen valloittajamentaliteetin avulla. ”Autopsykografia”-runossaan Pessoa esittää puolestaan runoilijaa koskevan modernin poetiikan ongelmineen: esittävyyteen perustuva taide etäännyttää kokijan – taiteilijan – aina väistämättä ensimmäisestä, spontaanista ja luonnollisesta kokemuksesta ja tekee hänestä teeskentelijän ja simulakrumien (Baudrillard), toisen tason merkityksen tuottajan. ”Autopsykografian” moderni poetiikka koskee myös lukijaa, joka ei tavoita runoilijan välittämää merkitystä vaan kolmannen tason merkityksen. ”Autopsykografian” runous- ja ihmiskäsitys on moderni: runoilija on ammattimainen teeskentelijä, lähtökohtaisesti vilpillinen ja epäautenttinen. Pessoa ja Campos edustavat Pessoan objektiivisia heteronyymejä ja myytin modernia puolta. Pessoan subjektiiviset heteronyymit Reis ja Caeiro täydentävät objektiviisia, modernin ihmisen ahdistusta ja levottomuutta ilmaisseita Pessoaa ja Camposta ollen luonteeltaan romanttisia vilpittömyyden kannattajia. Caeiro arvosti näköaistia yli muiden aistien. Hänen tavoitteenaan oli katsoa aina kuin ensimmäistä kertaa, spontaanisti ja välittömästi kuin lapsi. Reis puolestaan korosti harmoniaa jumalten, ihmisten ja luonnon välillä ja uskoi kohtuullisiin aistinautintoihin. Molemmat muodostivat Pessoan myytin romanttisen puolen yhteisessä halussaan hylätä sosiaaliset roolit ja opetukset ja palata kohti yksilöllistä minää. Vilpittömyys ja autenttisuus ovat Caeiron ja Reisin ohjeita runoilijalle ja ihmiselle. Objektiiviset ja subjektiiviset heteronyymit yhdessä muodostavat modernistis-romanttisen myytin, joka kokonaisuudessaan on looginen: objektiiviset heteronyymit esittivät teeskentelyn, vilpillisyyden ja moderniuden ongelmat; subjektiiviset tarjosivat ratkaisua niihin, poisopettelua sosiaalisista rooleista ja rohkeutta mennä kohti omaa yksilöllistä minuutta.

Measurement of the WW+WZ production cross section using a matrix element technique in lepton+jets events

We present a measurement of the $WW+WZ$ production cross section observed in a final state consisting of an identified electron or muon, two jets, and missing transverse energy. The measurement is carried out in a data sample corresponding to up to 4.6~fb$^{-1}$ of integrated luminosity at $\sqrt{s} = 1.96$ TeV collected by the CDF II detector. Matrix element calculations are used to separate the diboson signal from the large backgrounds. The $WW+WZ$ cross section is measured to be $17.4\pm3.3$~pb, in agreement with standard model predictions. A fit to the dijet invariant mass spectrum yields a compatible cross section measurement.

Direct Top-Quark Width Measurement at CDF

We present a measurement of the top-quark width using $t\bar{t}$ events produced in $p\bar{p}$ collisions at Fermilab's Tevatron collider and collected by the CDF II detector. In the mode where the top quark decays to a $W$ boson and a bottom quark, we select events in which one $W$ decays leptonically and the other hadronically~(lepton + jets channel) . From a data sample corresponding to 4.3~fb$^{-1}$ of integrated luminosity, we identify 756 candidate events. The top-quark mass and the mass of $W$ boson that decays hadronically are reconstructed for each event and compared with templates of different top-quark widths~($\Gamma_t$) and deviations from nominal jet energy scale~($\Delta_{JES}$) to perform a simultaneous fit for both parameters, where $\Delta_{JES}$ is used for the {\it in situ} calibration of the jet energy scale. By applying a Feldman-Cousins approach, we establish an upper limit at 95$\%$ confidence level~(CL) of $\Gamma_t $

Measurement of the top pair production cross section in the dilepton decay channel in pp̅ collisions at √s=1.96 TeV

A measurement of the $\ttbar$ production cross section in $\ppbar$ collisions at $\sqrt{{\rm s}}$ = 1.96 TeV using events with two leptons, missing transverse energy, and jets is reported. The data were collected with the CDF II Detector. The result in a data sample corresponding to an integrated luminosity 2.8 fb$^{-1}$ is: $\sigma_{\ttbar}$ = 6.27 $\pm$ 0.73(stat) $\pm$ 0.63(syst) $\pm$ 0.39(lum) pb. for an assumed top mass of 175 GeV/$c^{2}$.

Diffractive W and Z production at the Fermilab Tevatron

We report on a measurement of the fraction of events with a W or Z boson produced diffractively in antiproton-proton collisions at a center of mass energy of 1.96 TeV, using data from 0.6 inverse femtobarns of integrated luminosity collected with the CDF-II detector equipped with a Roman-pot spectrometer that detects the antiproton (pbar) from pbar+p --> pbar+[X+W/Z]. We find that (0.97 +/- 0.11)% of Ws and (0.85 +/- 0.22)% of Zs are produced diffractively in a region of (anti)proton fractional momentum loss (\xi) of 0.03-1t p+[X+W/Z]+pbar, and on exclusive Z production, pbar+p-->pbar+Z+p. No signal is seen above background for these processes, and comparisons are made with expectations.

Search for the supersymmetric partner of the top quark in pp̅ collisions at √s=1.96 TeV

We present a search for the lightest supersymmetric partner of the top quark in proton-antiproton collisions at a center-of-mass energy √s=1.96  TeV. This search was conducted within the framework of the R parity conserving minimal supersymmetric extension of the standard model, assuming the stop decays dominantly to a lepton, a sneutrino, and a bottom quark. We searched for events with two oppositely-charged leptons, at least one jet, and missing transverse energy in a data sample corresponding to an integrated luminosity of 1  fb-1 collected by the Collider Detector at Fermilab experiment. No significant evidence of a stop quark signal was found. Exclusion limits at 95% confidence level in the stop quark versus sneutrino mass plane are set. Stop quark masses up to 180  GeV/c2 are excluded for sneutrino masses around 45  GeV/c2, and sneutrino masses up to 116  GeV/c2 are excluded for stop quark masses around 150  GeV/c2.

Significant effects of Pgi genotype and body reserves on lifespan in the Glanville fritillary butterfly

Individuals with a particular variant of the gene phosphoglucose isomerase (Pgi ) have been shown to have superior dispersal capacity and fecundity in the Glanville fritillary butterfly (Melitaea cinxia), raising questions about the mechanisms that maintain polymorphism in this gene in the field. Here, we investigate how variation in the Pgi genotype affects female and male life history under controlled conditions. The most striking effect is the longer lifespan of genotypes with high dispersal capacity, especially in nonreproducing females. Butterflies use body reserves for somatic maintenance and reproduction, but
different resources (in thorax versus abdomen) are used under dissimilar conditions, with some interactions with the Pgi genotype. These results indicate life-history trade-offs that involve resource allocation and genotype!environment interactions, and these trade-offs are likely to contribute to the maintenance of Pgi polymorphism in the natural populations.

Top Quark Mass Measurement in the lepton+jets Channel Using a Matrix Element Method and in situ Jet Energy Calibration

A precision measurement of the top quark mass m_t is obtained using a sample of ttbar events from ppbar collisions at the Fermilab Tevatron with the CDF II detector. Selected events require an electron or muon, large missing transverse energy, and exactly four high-energy jets, at least one of which is tagged as coming from a b quark. A likelihood is calculated using a matrix element method with quasi-Monte Carlo integration taking into account finite detector resolution and jet mass effects. The event likelihood is a function of m_t and a parameter DJES to calibrate the jet energy scale /in situ/. Using a total of 1087 events, a value of m_t = 173.0 +/- 1.2 GeV/c^2 is measured.

Updated search for the flavor-changing neutral-current decay D0→μ+μ- in pp̅ collisions at √s=1.96 TeV

We report on a search for the flavor-changing neutral-current decay D0 \to {\mu}+ {\mu}- in pp collisions at \surd s = 1.96 TeV using 360 pb-1 of integrated luminosity collected by the CDF II detector at the Fermilab Tevatron collider. A displaced vertex trigger selects long-lived D0 candidates in the {\mu}+ {\mu}-, {\pi}+{\pi}-, and K-{\pi}+ decay modes. We use the Cabibbo-favored D0 \to K-{\pi}+ channel to optimize the selection criteria in an unbiased manner, and the kinematically similar D0 \to{\pi}+ {\pi}- channel for normalization. We set an upper limit on the branching fraction (D0 --> {\mu}+ {\mu}-)

Improved Search for a Higgs Boson Produced in Association with Z→l+l- in pp̅ Collisions at √s=1.96 TeV

We present a search for the standard model Higgs boson produced with a Z boson in 4.1 fb^-1 of data collected with the CDF II detector at the Tevatron. In events consistent with the decay of the Higgs boson to a bottom-quark pair and the Z boson to electrons or muons, we set 95% credibility level upper limits on the ZH production cross section times the H -> b bbar branching ratio. Improved analysis methods enhance signal sensitivity by 20% relative to previous searches beyond the gain due to the larger data sample. At a Higgs boson mass of 115 GeV/c^2 we set a limit of 5.9 times the standard model value.

Accumulation of point mutations and reassortment of genomic RNA segments are involved in the microevolution of Puumala hantavirus in a bank vole (Myodes glareolus) population

"The genetic diversity of Puumala hantavirus (PUUV) was studied in a local population of its natural host, the bank vole (Myodes glareolus). The trapping area (2.5x2.5 km) at Konnevesi, Central Finland, included 14 trapping sites, at least 500 m apart; altogether, 147 voles were captured during May and October 2005. Partial sequences of the S, M and L viral genome segments were recovered from 40 animals. Seven, 12 and 17 variants were detected for the S, M and L sequences, respectively; these represent new wild-type PUUV strains that belong to the Finnish genetic lineage. The genetic diversity of PUUV strains from Konnevesi was 0.2-4.9% for the S segment, 0.2-4.8% for the M segment and 0.2-9.7% for the L segment. Most nucleotide substitutions were synonymous and most deduced amino acid substitutions were conservative, probably due to strong stabilizing selection operating at the protein level. Based on both sequence markers and phylogenetic clustering, the S, M and L sequences could be assigned to two groups, 'A' and 'B'. Notably, not all bank voles carried S, M and L sequences belonging to the same group, i.e. SAMALA or SBMBLB.. A substantial proportion (8/40, 20%) of the newly characterized PUUV strains possessed reassortant genomes such as SBMALA, SAMBLB or SBMALB. These results suggest that at least some of the PUUV reassortants are viable and can survive in the presence of their parental strains."
