Mielipiteitä LTY:n Origosta - Kyselyraportti

Lappeenrannan teknillisen yliopiston kirjasto on kokenut viime vuosina muutoksia: palveluiden lisäännyttyä ja tilojen laajennettua ei sen nimikään ole voinut säilyä samana. Nykyisin kirjastoalueen varastoa, kirjastotilaa alakerrassa, yläkertaa ja yläkerrasta alkavia oppimiskeskuksen tiloja kutsutaan yhteisnimellä Origo. Marraskuussa 2006 laadittiin mielipidekysely, jossa kartoitettiin eri aihealueita liittyen Origon tiloihin sekä sen palveluihin ja niiden käyttöön. Vastauksia saatiin 454 kappaletta. Saadut vastaukset käsiteltiin ja koottiin tähän raporttiin. Myös itse kyselylomake on nähtävissä raportin lopussa. Kyselyn tuloksista kävi ilmi, että suurin osa vastaajista on ymmärtänyt, mitä Origo pitää sisällään. Kaikille nimenmuutos ei ole ollut kuitenkaan helppo: Origo miellettiin usein yläkerran muodostamaksi kokonaisuudeksi. Suurin osa vastaajista ilmoitti vierailevansa Origossa useita kertoja viikossa, ja suosituimmaksi syyksi nousi kirjastomateriaalin lainaus. Myös tulostaminen ja tiedonetsintä olivat yleisiä Origossa käynnin syitä. Origon tiloihin ja viihtyvyyteenoltiin keskimäärin tyytyväisiä, mutta etenkin ryhmätyö- ja luokista toivottiin lisää informaatiota, ja työskentelypaikkoja kaivattaisiin lisää. Palveluista eniten käytettyjä ovat kirjojen lainaus ja tiedon haku Wilma-tietokannasta. Näiden kahden lisäksi yksi tärkeimmiksi koetuista palveluista oli myös kirjojen varaus. Kirjojen varaukseen tosin toivottaisiin sähköinen mahdollisuus. Wilma-tietokanta koettiin myös ylivoimaisesti hyödyllisimmäksi tietolähteeksi. Jokainen palvelupiste (lainaus, tietopalvelu sekä yläkerran neuvonta) koettiin tärkeiksi, ja mielikuva Origosta olikin useimpien vastausten perusteella myönteinen. Kyselyn lopuksi vastaajat saivat vielä antaa parannusehdotuksia ja muita kommentteja liittyen Origon toimintaan.

Aproximación multicriterio a la estructura industrial de la economía española

El trabajo presenta una forma alternativa de analizar la estructura industrial de la economía española. En concreto, el estudio se interesa tanto por la vertiente de la estructura productiva sectorial, como por la vertiente de la especialización territorial. Mediante la técnica multicriterio se acceden a programas de optimización que, a partir de las variables que se consideran más relevantes (empleo, valor añadido y número de establecimientos) determina, por un lado, qué sectores son los más significativos dentro del tejido industrial de la economía española, y por otro lado, se llega a determinar qué Comunidades Autónomas son las que adquieren mayor peso relativo para cada uno de los sectores industriales.

Results of Anterior Tucking of the Superior Oblique Muscle Tendon in Bilateral Fourth Nerve Palsy.

Background: Bilateral fourth nerve palsy is characterised by excyclotorsion, which can be corrected by reinforcement of the anterior tendon fibres of the superior oblique muscle. Patients and Methods: A retrospective study of 40 consecutive patients with bilateral acquired fourth nerve palsy operated by a selective tuck of the anterior portion of the superior oblique tendon between 1994 and 2012 was undertaken. Horizontal, vertical and torsional deviations were measured in 9 diagnostic positions of gaze and the field of binocular single vision was evaluated with the Harms tangent screen. Postoperative follow-ups took place at 1 week, 6 months, and ≥ 3 years. Results: Preoperative mean excyclotorsion was 9° in the primary position and 15° in downgaze. These values decreased to 2° and 5° 6 months after surgery, and 2.5° and 6° at ≥ 3 years. Immediate post-operative incyclotorsion in upgaze (28 patients) and Brown syndrome (15 patients) regressed spontaneously. The median score of field of binocular single vision improved from 4 % preoperatively to 76 % postoperatively. Conclusions: The selective tuck of the anterior tendon fibers of the superior oblique tendon enables an efficient and long-lasting correction of the ocular torsion induced by bilateral trochlear palsy.

Declining diversity of egg-associated bacteria during development of naturally spawned whitefish embryos (Coregonus spp.)

Fish eggs are associated with microbes, whose roles range from mutualism to parasitism. Recent laboratory experiments have shown that the taxonomic composition of associated microbial communities on the egg influences embryonic development. Host genetics also plays an important role in determining the consequences for embryonic growth and survival in this interaction. Moreover, it has been found that the importance of host genetics increases during embryogenesis. These findings suggest that during embryogenesis, the host increasingly influences the composition of its associated microbial community. However, little is known about the composition of microbial communities associated with naturally spawned eggs in the wild. We sampled fertilized whitefish eggs (Coregonus spp.) of different developmental stages from six sub-Alpine lakes and used a universal primer pair and 454 pyrosequencing in order to describe the taxonomic composition of egg-associated bacterial communities. We found bacterial communities on early embryos to be very diverse and to resemble the bacterial composition of the surrounding water environment. The bacterial communities on late embryos were significantly less diverse than on early embryos and displayed a clear shift in taxonomic composition that corresponded poorly with the bacterial composition of the surrounding water environment. The main bacterial components on whitefish eggs in this study were Proteobacteria, Actinobacteria, and Firmicutes, while the five most common families were Leuconostocaceae, Streptococcaceae, Comamonadaceae, Oxalobacteraceae and Moraxellaceae. Their putative relationships with the host are discussed. We conclude that natural symbiotic bacterial communities become more specialized during embryogenesis because of specific interactions with their embryo host.

Etelä-Karjalan aluebarometri

Tutkimuksen päätavoitteena oli rakentaa Etelä-Karjalan maakunnan alueellinen suhdannebarometri. Aluebarometrilla kuvataan ja analysoidaan alueen toimialojen tuotannon ja työllisyyden kehitystä sekä nykytilannetta tuoreilla, havainnollisilla ja luotettavilla indikaattoreilla. Tutkimusmenetelmänä on konstruktiivinen tutkimus. Aluebarometri toteutettiin kyselytutkimuksena 454:ltä yritykseltä Etelä-Karjalan alueella keväällä 2002. Tulokset on raportoitu toimialoittain sisältäen kyselytutkimuksen 11 indikaattoria sekä kaksi tilastollista muuttujaa. Teoriaosassa tarkasteltiin aluetalouden rakentumista, aluekehitystä, yritysten sijaintiteorioita ja systeemidynamiikkaa. Barometrin konstruoinnin lisäksi empiirisessä osassa analysoitiin maakunnan yritystoiminnan ja toimialarakenteen tyypillisiä piirteitä sekä selvitettiin barometrin käyttäjäkunnan tietotarpeita. Tutkimustulosten mukaan Etelä-Karjalan yritykset odottavat aluebarometrin indikaattoreiden kehittyvän seuraavan kuuden kuukauden ajanjaksolla lievästi myönteiseen suuntaan. Myönteisintä kehitystä odotetaan myynnin ja Venäjän yleisen suhdannetilanteen suhteen. Toimialoista positiivisimmat odotukset ovat informaatioteknologian, liike-elämän palveluiden, muiden palveluiden sekä kaupan aloilla, heikoimmat puolestaan rakentamisen alalla.

L'ordinaire en partage : le courrier des lecteurs à Georges Simenon

Cette thèse est consacrée à l'étude du courrier que l'écrivain Georges Simenon (1903-1989) recevait de la part de ses lecteurs et de ses admirateurs inconnus. Ils sont près de 6000 à s'être adressés, par courrier postal, à l'auteur célèbre des Maigret, entre 1945 et jusqu'à sa mort. Ces lettres, auxquelles l'écrivain répondait quasi systématiquement sont archivées au Fonds Simenon de l'Université de Liège mais n'ont jusqu'alors pas fait l'objet d'étude, contrairement à la correspondance que l'auteur a échangée avec des auteurs comme André Gide ou Henry Miller. La thèse s'arrête sur une portion de cet échange inédit, soit un peu plus de 2000 missives reçues entre 1946 et 1973. Ce courrier est le point de départ d'une démarche inspirée par le cas singulier que Simenon représente dans l'histoire des lettres, de par son succès, sa large audience et son double positionnement en tant qu'auteur grand public et écrivain aux ambitions littéraires. Cette étude empirique du lectorat d'un auteur de bestsellers va au-delà de l'approche sociologique courante concernant Simenon, qui s'intéresse en priorité à la position et à la posture du créateur face à ses pairs, aux médias et aux institutions (Bourdieu) mais ignore, tout comme une bonne partie des études littéraires et par effet d'un ethnocentrisme lettré, le lecteur « ordinaire ». Une sociologie pragmatique plus compréhensive du vécu de l'ensemble des acteurs - lecteurs compris - (Boltanski, Heinich) a dès lors été privilégiée. Ce sont plus particulièrement les valeurs engagées dans le rapport à l'écrivain et les fonctions que les correspondants réservent à ce « grand singulier » qui sont examinées. Les lettres attribuent en effet à l'écrivain divers rôles (aide, confident ou consolateur). On apprend ainsi dans quelles proportions la lecture « ordinaire » mais aussi nos rapports les plus courants aux objets culturels, sont constitués d'une attention oscillant de l'oeuvre à la personne du créateur. Ces témoignages s'inscrivent en toile de fond d'un enjeu plus large qui concerne l'évolution de l'image et du rôle de l'écrivain dans notre société : en particulier dans le contexte culturel médiatique de la seconde moitié du XXe siècle, où cette image entre plus que jamais en concurrence avec les arts visuels et de divertissement dits de « masse », conduisant les valeurs littéraires à s'affronter aux valeurs de la visibilité et de la célébrité ainsi qu'aux valeurs commerciales.

Ability of physicians to diagnose influenza and usefulness of a rapid influenza antigen test in febrile returning travelers: A randomized controlled trial.

BACKGROUND: Fever is a frequent cause of medical consultation among returning travelers. The objectives of this study were to assess whether physicians were able to identify patients with influenza and whether the use of an influenza rapid diagnostic test (iRDT) modified the clinical management of such patients. METHODS: Randomized controlled trial conducted at 2 different Swiss hospitals between December 2008 and November 2012. Inclusion criteria were 1) age ≥18 years, 2) documented fever of ≥38 °C or anamnestic fever + cough or sore throat within the last 4 days, 3) illness occurring within 14 days after returning from a trip abroad, 4) no definitive alternative diagnosis. Physicians were asked to estimate the likelihood of influenza on clinical grounds, and a single nasopharyngeal swab was taken. Thereafter patients were randomized into 2 groups: i) patients with iRDT (BD Directigen A + B) performed on the nasopharyngeal swab, ii) patients receiving usual care. A quantitative PCR to detect influenza was done on all nasopharyngeal swabs after the recruitment period. Clinical management was evaluated on the basis of cost of medical care, number of X-rays requested and prescription of anti-infective drugs. RESULTS: 100 eligible patients were referred to the investigators. 93 patients had a naso-pharyngeal swab for a PCR and 28 (30%) swabs were positive for influenza. The median probability of influenza estimated by the physician was 70% for the PCR positive cases and 30% for the PCR negative cases (p < 0.001). The sensitivity of the iRDT was only 20%, and specificity 100%. Mean medical cost for the patients managed with iRDT and without iRDT were USD 581 (95%CI 454-707) and USD 661 (95%CI 522-800) respectively. 14/60 (23%) of the patients managed with iRDT were prescribed antibiotics versus 13/33 (39%) in the control group (p = 0.15). No patient received antiviral treatment. CONCLUSION: Influenza was a frequent cause of fever among these febrile returning travelers. Based on their clinical assessment, physicians had a higher level of suspicion for influenza in PCR positive cases. The iRDT used in this study showed a disappointingly low sensitivity and can therefore not be recommended for the management of these patients. TRIAL REGISTRATION: ClinicalTrials.gov NCT00821626.

Transcriptomics of In Vitro Immune-Stimulated Hemocytes from the Manila Clam Ruditapes philippinarum Using High-Throughput Sequencing

The Manila clam (Ruditapes philippinarum) is a worldwide cultured bivalve species with important commercial value. Diseases affecting this species can result in large economic losses. Because knowledge of the molecular mechanisms of the immune response in bivalves, especially clams, is scarce and fragmentary, we sequenced RNA from immune-stimulated R. philippinarum hemocytes by 454-pyrosequencing to identify genes involved in their immune defense against infectious diseases.

The risk factors for fractures and trabecular bone-score value in patients with endogenous Cushing's syndrome.

In a cohort study of 182 consecutive patients with active endogenous Cushing's syndrome, the only predictor of fracture occurrence after adjustment for age, gender bone mineral density (BMD) and trabecular bone score (TBS) was 24-h urinary free cortisol (24hUFC) levels with a threshold of 1472 nmol/24 h (odds ratio, 3.00 (95 % confidence interval (CI), 1.52-5.92); p = 0.002). INTRODUCTION: The aim was to estimate the risk factors for fracture in subjects with endogenous Cushing's syndrome (CS) and to evaluate the value of the TBS in these patients. METHODS: All enrolled patients with CS (n = 182) were interviewed in relation to low-traumatic fractures and underwent lateral X-ray imaging from T4 to L5. BMD measurements were performed using a DXA Prodigy device (GEHC Lunar, Madison, Wisconsin, USA). The TBS was derived retrospectively from existing BMD scans, blinded to clinical outcome, using TBS iNsight software v2.1 (Medimaps, Merignac, France). Urinary free cortisol (24hUFC) was measured by immunochemiluminescence assay (reference range, 60-413 nmol/24 h). RESULTS: Among enrolled patients with CS (149 females; 33 males; mean age, 37.8 years (95 % confidence interval, 34.2-39.1); 24hUFC, 2370 nmol/24 h (2087-2632), fractures were confirmed in 81 (44.5 %) patients, with 70 suffering from vertebral fractures, which were multiple in 53 cases; 24 patients reported non-vertebral fractures. The mean spine TBS was 1.207 (1.187-1.228), and TBS Z-score was -1.86 (-2.07 to -1.65); area under the curve (AUC) was used to predict fracture (mean spine TBS) = 0.548 (95 % CI, 0.454-0.641)). In the final regression model, the only predictor of fracture occurrence was 24hUFC levels (p = 0.001), with an increase of 1.041 (95 % CI, 1.019-1.063), calculated for every 100 nmol/24-h cortisol elevation (AUC (24hUFC) = 0.705 (95 % CI, 0.629-0.782)). CONCLUSIONS: Young patients with CS have a low TBS. However, the only predictor of low traumatic fracture is the severity of the disease itself, indicated by high 24hUFC levels.

Characterization of thirty two microsatellite loci for three Atlanto-Mediterranean echinoderm species

Thirty two microsatellites were optimized from 454 pyrosequencing libraries for three Atlanto-Mediterranean echinoderms: Coscinasterias tenuispina, Echinaster sepositus and Arbacia lixula. We observed different frequency of microsatellite types (di-, tri-, tetra- and pentanucleotide) throughout the genome of the species, but no significant differences were observed in allele richness among different microsatellite repeats. No loci showed linkage disequilibrium. Heterozygosity deficit and departure from Hardy Weinberg equilibrium were observed for some loci, in two species, probably due to high levels of inbreeding. Heterozygosity excess observed in C. tenuispina could be explained by selection against homozygotes and/or outcrossing.

The composition of airborne and grain-dust fungal communities is shaped at regional scale by plant genotypes and farming practices

Chronic exposure to airborne fungi has been associated with different respiratory symptoms and pathologies in occupational populations, such as grain workers. However, the homogeneity in the fungal species composition of these bioaerosols on a large geographical scale and the different drivers that shape these fungal communities remain unclear. In this study, the diversity of fungi in grain dust and in the aerosols released during harvesting was determined across 96 sites at a geographical scale of 560 km(2) along an elevation gradient of 500 m by tag-encoded 454-pyrosequencing of the internal transcribed spacer (ITS) sequences. Associations between the structure of fungal communities in the grain dust and different abiotic (farming system, soil characteristics, geographic and climatic parameters) and biotic (wheat cultivar, previous crop culture) factors were explored. These analyses revealed a strong relationship between the airborne and grain dust fungal communities and showed the presence of allergenic and mycotoxigenic species in most samples, which highlights the potential contribution of these fungal species to work-related respiratory symptoms of grain workers. The farming system was the major driver of the alpha and beta phylogenetic diversity of fungal communities. In addition, elevation and soil CaCO3 concentrations shaped the alpha diversity whereas wheat cultivar, cropping history and the number of freezing days per year shaped the taxonomic beta diversity of these communities.
