Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Förord av Björn Brorström, Prorektor Högskolan i Borås Ett professionslärosäte bedriver utbildning och forskning på vetenskaplig grund. Vetenskapliga metoder tillämpas och framkomna resultat prövas för att säkra tillförlitlighet och relevans. Förmågan att problematisera, formulera frågor och välja lämpliga metoder för att besvara frågor är egenskaper för god forskning och utmärkande för en stark utbildnings- och forskningsmiljö. Vid ett professionslärosäte finns samtidigt en stark strävan efter att i utbildning och forskning ta till vara den kunskap och de erfarenheter som professioner besitter och därigenom säkra en hög grad av praktisk relevans. Växelverkan mellan teori och praktik och erfarenhetsutbyte mellan forskare och praktiker är ständigt pågående. Det finns ingen avslutning på processen utan den pågår utan avbrott. En nödvändig förutsättning för ett fruktbart samarbete är en ömsesidig respekt och vilja att stödja och ifrågasätta varandra. Forskaren måste vara beredd på kritik för bristen på praktisk relevans och professionsföreträdaren måste vara beredd på att förtrogenhetskunskapens lämplighet ifrågasätts. Det är en fråga om med- och mothåll från båda håll i syfte att långsiktigt utveckla teori och praktik. Det är en utmaning att utveckla, etablera och därefter kontinuerligt försvara och förbättra professionslärosätet. Ett led i utvecklingen är att inom ramen för Högskolan i Borås föra en debatt om innebörden av ett professionslärosäte och vad vi behöver göra för att förbättra verksamheten. På uppdrag av rektor Lena Nordholm har medarbetare vid Bibliotekshögskolan utvecklat och ansvarat för en seminarieserie benämnd Profession och vetenskap. Seminarierna spände över ett brett fält. En av många viktiga frågor som diskuterades flitigt var huruvida vi ska forska om professioner, i för eller med, eller kanske alltihop samtidigt. Bidragen publiceras nu i denna antologi som ges ut inom ramen för Högskolan i Borås rapportserie Vetenskap för profession. Rapporten Profession och vetenskap – idéer och strategier för ett professionslärosäte, som redigerats av universitetsadjunkt Maria Lindh, kommer att få stor betydelse inom lärosätet och i vårt samarbete med företrädare för näringsliv, kulturliv och offentlig verksamhet. Jag ser det som en intressant fortsättning att anordna ett antal seminarier med inbjudna representanter för professioner där artiklarna i denna rapport kan ligga till grund för erfarenhetsutbyte och diskussioner.

Forskningsöversikt (refereegranskat)abstract
- We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLID experiment using a polarised beam at SLC. The measurements include cross-sections, forward-backward asymmetries and polarised asymmetries. The mass and width of the Z boson, m(Z) and Gamma(Z), and its couplings to fermions, for example the p parameter and the effective electroweak mixing angle for leptons, are precisely measured: m(Z) = 91.1875 +/- 0.0021 GeV, Gamma(Z) = 2.4952 +/- 0.0023 GeV, rho(l) = 1.0050 +/- 0.0010, sin(2)theta(eff)(lept) = 0.23153 +/- 0.00016. The number of light neutrino species is determined to be 2.9840 +/- 0.0082, in agreement with the three observed generations of fundamental fermions. The results are compared to the predictions of the Standard Model (SM). At the Z-pole, electroweak radiative corrections beyond the running of the QED and QCD coupling constants are observed with a significance of five standard deviations, and in agreement with the Standard Model. Of the many Z-pole measurements, the forward-backward asymmetry in b-quark production shows the largest difference with respect to its SM expectation, at the level of 2.8 standard deviations. Through radiative corrections evaluated in the framework of the Standard Model, the Z-pole data are also used to predict the mass of the top quark, m(t) = 173(+10)(+13) GeV, and the mass of the W boson, m(W) = 80.363 +/- 0.032 GeV. These indirect constraints are compared to the direct measurements, providing a stringent test of the SM. Using in addition the direct measurements of m(t) and m(W), the mass of the as yet unobserved SM Higgs boson is predicted with a relative uncertainty of about 50% and found to be less than 285 GeV at 95% confidence level.

- Autism spectrum disorders (ASDs) are common, heritable neurodevelopmental conditions. The genetic architecture of ASDs is complex, requiring large samples to overcome heterogeneity. Here we broaden coverage and sample size relative to other studies of ASDs by using Affymetrix 10K SNP arrays and 1,168 families with at least two affected individuals, performing the largest linkage scan to date while also analyzing copy number variation in these families. Linkage and copy number variation analyses implicate chromosome 11p12-p13 and neurexins, respectively, among other candidate loci. Neurexins team with previously implicated neuroligins for glutamatergic synaptogenesis, highlighting glutamate-related genes as promising candidates for contributing to ASDs.

- We have searched for a heavy resonance decaying into a Z+jet final state in p (p) over bar collisions at a center of mass energy of 1.96 TeV at the Fermilab Tevatron collider using the D0 detector. No indication for such a resonance was found in a data sample corresponding to an integrated luminosity of 370 pb(-1). We set upper limits on the cross section times branching fraction for heavy resonance production at the 95% C.L. as a function of the resonance mass and width. The limits are interpreted within the framework of a specific model of excited quark production.

- The DO experiment enjoyed a very successful data-collection run at the Fermilab Tevatron collider between 1992 and 1996. Since then, the detector has been upgraded to take advantage of improvements to the Tevatron and to enhance its physics capabilities. We describe the new elements of the detector, including the silicon microstrip tracker, central fiber tracker, solenoidal magnet, preshower detectors, forward muon detector, and forward proton detector. The uranium/liquid -argon calorimeters and central muon detector, remaining from Run 1, are discussed briefly. We also present the associated electronics, triggering, and data acquisition systems, along with the design and implementation of software specific to DO.

Tidskriftsartikel (refereegranskat)abstract
- An amino-terminal region of a, chain of type IV collagen noncollagenous domain [alpha(3)(IV)NC1] that induces experimental autoimmune glomerulortephritis (EAG) in rats has been identified. Only recombinant antigens that contain a nine-amino acid (AA) span of alpha(3)(IV)NC1, consistent with a T cell epitope, could induce EAG. It was hypothesized that synthetic peptides of this region should induce EAG. Human and rat peptides of this region were synthesized and rats were immunized to define the nephritogenic epitope. A 13-AA rat peptide induced EAG with proteinuria, decreased renal function, and glomerular basement membrane (GBM)-bound deposits in half of the rats. This peptide induces lymph node cell proliferation and development of antibodies to epitopes of alpha(3)(IV)NC1 external to the peptide immunogen. Carboxy-terminal extension to 21 amino acids results in all rats' demonstrating anti-GBM antibody and severe EAG. Asparagine at position 19 is critical for EAG induction. None of the 50 rats that were immunized with peptide that contained human sequence with isoleucine at position 19 developed EAG, whereas rat sequence with asparagine 19 induced EAG. Truncation of amino terminal AA of the peptide aborts EAG induction. These studies demonstrate that a T cell epitope of alpha(3)(IV)NC1 induces lymph node cell proliferation, EAG, and intramolecular epitope spreading; that the length of this peptide influences the formation of anti-GBM antibody; and that the presence of asparagine at position 19 of the peptide is critical to disease induction.

- Goodpasture's syndrome is an autoimmune disease characterized by pulmonary hemorrhage, glomerulonephritis, and antiglomerular basement membrane (GBM) antibodies. We have studied a rat model with chimeric proteins (CPs) consisting of portions of the nephritogenic non-collagenous domain of alpha3 type IV collagen (alpha3(IV)NC1) and non-nephritogenic alpha1(IV)NC1. CPs with aminoterminal alpha3 that contains the major epitope for Goodpasture antibody binding induced EAG. We next immunized with D3, an alpha1(IV)NC1 CP with 69AA of alpha3(IV)NC1 (binds Goodpasture sera), D4, the D3 construct shortened by 4 AA (nonbinding), P9 and P10, single AA mutants (nonbinding) and S2, an alpha1(IV)NC1 with nine AA of alpha3(IV)NC1 (binding). GBM, S2 and D3 induced EAG. GBM immunized rats had intense IgG deposits but S2 and D3 rats had minimal deposits. A 13 mer rat peptide encompassing the aminoterminal site induced EAG sans antibody, while peptides not encompassing the region failed to induce GN. Asparagine at position 19 rather than isoleucine was essential for disease induction. These studies define critical limited AA sequences of alpha3(IV)NC1 associated with glomerulonephritis without antibody, and demonstrate that this region contains a T-cell epitope responsible for induction of glomerulonephritis.

- This group previously identified a peptide p13 of alpha 3(IV)NC1 domain of type IV collagen that induces experimental autoimmune glomerulonephritis (EAG) in rats with generation of antibodies to sites on alpha 3(IV)NC1 external to the peptide as a result of intramolecular epitope spreading. It was hypothesized that intermolecular epitope spreading to other collagen IV chains also was induced. Rats were immunized with nephritogenic peptide that was derived from the amino terminal part of rat alpha 3(IV)NC1 domain, and serum and kidney eluate were examined for antibodies to both native and recombinant NC1 domains of collagen IV. Peptide induced EAG with proteinuria and decreased renal function and glomerular basement membrane IgG deposits. Sera from these rats were examined by ELISA, which revealed reactivity not only to immunizing peptide but also to human and rat alpha 3(IV)NC1 and to human alpha 4(IV)NC1 domains. Kidney eluate that was depleted of alpha 3(IV)NC1 antibodies still reacted to alpha 4(IV)NC1, and alpha 3(IV)NC1 column-bound antibody reacted with alpha 3(IV)NC1. There was minimal reactivity to other collagen chains. Eluate that was adsorbed to NC1 hexamer from rat glonterular basement membrane lost all reactivity to glomerular constituents, and the eluted antibodies reacted to alpha 3(IV)NC1 and alpha 4(IV)NC1 domains. These studies show that a T cell epitope of alpha 3(IV)NC1 induces EAG, intramolecular epitope spreading along alpha 3(IV)NC1, and intermolecular epitope spreading to alpha 4(IV)NC1 domain with minimal or no reactivity to other collagen chains or glomerular constituents. This is the first demonstration in EAG of intermolecular epitope spreading and identification of the spread epitopes.
