Does bacterial density in cystic fibrosis sputum increase prior to pulmonary exacerbation?

These findings strongly suggest that CFPE do not generally result from increased bacterial density within the airways. Instead, data presented here are consistent with alternative models of pulmonary exacerbation.

Analysis of the regional pattern of sea level change due to ocean dynamics and density changes for 1993-2099 in observations and CMIP5 AOGCMs

Predictions of twenty-first century sea level change show strong regional variation. Regional sea level change observed by satellite altimetry since 1993 is also not spatially homogenous. By comparison with historical and pre-industrial control simulations using the atmosphere–ocean general circulation models (AOGCMs) of the CMIP5 project, we conclude that the observed pattern is generally dominated by unforced (internal generated) variability, although some regions, especially in the Southern Ocean, may already show an externally forced response. Simulated unforced variability cannot explain the observed trends in the tropical Pacific, but we suggest that this is due to inadequate simulation of variability by CMIP5 AOGCMs, rather than evidence of anthropogenic change. We apply the method of pattern scaling to projections of sea level change and show that it gives accurate estimates of future local sea level change in response to anthropogenic forcing as simulated by the AOGCMs under RCP scenarios, implying that the pattern will remain stable in future decades. We note, however, that use of a single integration to evaluate the performance of the pattern-scaling method tends to exaggerate its accuracy. We find that ocean volume mean temperature is generally a better predictor than global mean surface temperature of the magnitude of sea level change, and that the pattern is very similar under the different RCPs for a given model. We determine that the forced signal will be detectable above the noise of unforced internal variability within the next decade globally and may already be detectable in the tropical Atlantic.

Steric sea level variability (1993-2010) in an ensemble of ocean reanalyses and objective analyses

Quantifying the effect of the seawater density changes on sea level variability is of crucial importance for climate change studies, as the sea level cumulative rise can be regarded as both an important climate change indicator and a possible danger for human activities in coastal areas. In this work, as part of the Ocean Reanalysis Intercomparison Project, the global and regional steric sea level changes are estimated and compared from an ensemble of 16 ocean reanalyses and 4 objective analyses. These estimates are initially compared with a satellite-derived (altimetry minus gravimetry) dataset for a short period (2003–2010). The ensemble mean exhibits a significant high correlation at both global and regional scale, and the ensemble of ocean reanalyses outperforms that of objective analyses, in particular in the Southern Ocean. The reanalysis ensemble mean thus represents a valuable tool for further analyses, although large uncertainties remain for the inter-annual trends. Within the extended intercomparison period that spans the altimetry era (1993–2010), we find that the ensemble of reanalyses and objective analyses are in good agreement, and both detect a trend of the global steric sea level of 1.0 and 1.1 ± 0.05 mm/year, respectively. However, the spread among the products of the halosteric component trend exceeds the mean trend itself, questioning the reliability of its estimate. This is related to the scarcity of salinity observations before the Argo era. Furthermore, the impact of deep ocean layers is non-negligible on the steric sea level variability (22 and 12 % for the layers below 700 and 1500 m of depth, respectively), although the small deep ocean trends are not significant with respect to the products spread.

Questioning Kenneth N. Waltz (1924-2013)

Two little-known academics examine the doctoral thesis of a young theorist, Kenneth Waltz. They conclude that his work is important, despite its ambiguities. Some years later, they catch up with Professor Waltz between classes and explore how his ideas have developed.

Revision of the new wandering spider genus Ohvida and taxonomic remarks on Celaetycheus Simon, 1897 (Araneae: Ctenidae)

The new ctenid genus Ohvida is proposed to include eight species: Ohvida fulvorufa (Franganillo, 1931) comb. nov. (type species) (=Celaetycheus cabriolatus Franganillo, 1930 syn. nov.; = C. cabriolatus pardosiformis Franganillo, 1930 syn. nov.; = C. fulvorufus afoliatus Franganillo, 1931 syn. nov.), O. isolata (Bryant, 1940) comb. nov., O. vernalis (Bryant, 1940) comb. nov., O. brevitarsus (Bryant, 1940) comb. nov., O. coxanus (Bryant, 1940), comb. nov., and three new species, O. turquino sp. nov. (all species from Cuba), and O. andros sp. nov. and O. bimini sp. nov. (both species from The Bahamas). Species of Ohvida differ from all other ctenid spiders by the presence of a retrodorsal projection on the cymbium of the male pedipalp and by a basal position of the lateral spurs on the female epigyne. The genus Celaetycheus Simon, 1897 is reviewed to only include its type species, C. flavostriatus Simon, 1897 from Brazil. We propose the following synonyms and new combinations: Ctenus ottleyi (Petrunkevitch, 1930) (= Celaetycheus strenuus Bryant, 1942 syn. nov. and C. modestus Bryant, 1942 syn. nov.); Ctenus delesserti (Caporiacco, 1947) comb. nov., and Leptoctenus paradoxus (F.O. P.-Cambridge, 1900) comb. nov. Celaetycheus modestus Bryant, 1942 is considered incertae sedis.

Characterization of the optical properties of atmospheric aerosols in Amazonia from long-term AERONET monitoring (1993-1995 and 1999-2006)

We present a new climatology of atmospheric aerosols (primarily pyrogenic and biogenic) for the Brazilian tropics on the basis of a high-quality data set of spectral aerosol optical depth and directional sky radiance measurements from Aerosol Robotic Network (AERONET) Cimel Sun-sky radiometers at more than 15 sites distributed across the Amazon basin and adjacent Cerrado region. This network is the only long-term project (with a record including observations from more than 11 years at some locations) ever to have provided ground-based remotely-sensed column aerosol properties for this critical region. Distinctive features of the Amazonian area aerosol are presented by partitioning the region into three aerosol regimes: southern Amazonian forest, Cerrado, and northern Amazonian forest. The monitoring sites generally include measurements from the interval 1999-2006, but some sites have measurement records that date back to the initial days of the AERONET program in 1993. Seasonal time series of aerosol optical depth (AOD), angstrom ngstrom exponent, and columnar-averaged microphysical properties of the aerosol derived from sky radiance inversion techniques (single-scattering albedo, volume size distribution, fine mode fraction of AOD, etc.) are described and contrasted for the defined regions. During the wet season, occurrences of mineral dust penetrating deep into the interior were observed.

Barnmorskor 1897 : En undersökning av barnmorskornas livs- och arbetsvillkor i Falu provinsialläkardistrikt

Syftet med denna uppsats har varit att klargöra livs- och arbetsförhållandena för barnmorskorna i Falu provinsialläkardistrikt under senare delen av 1800-talet. Det finns forskning som menar att landsortsbarnmorskorna från förra sekelskiftet och bakåt oftast var gifta och/eller hade egna barn, och denna slutsats har inspirerat till föreliggande arbete. Med utgångspunkt i samtliga distriktsbarnmorskors civilstånd, ev. moderskap, ålder och ursprung år 1897, har sedan ett mindre antal valts ut för en djupare granskning. Undersökningen har alltså varit tudelad. Resultatet som helhet visar bl.a. att de flesta barnmorskorna var ogifta och barnlösa år 1897. Den djupare granskningen visar dessutom stor variation i livs- och arbetsvillkor, där exempelvis löner och arbetsbörda var mycket olika. Vidare forskning kring frågor som t. ex. beräkningsgrunderna för kontantlönerna, skulle nyansera bilden ytterligare.

Bildbar och ofarlig för omgivningen : En studie av 18 sinnesslöa skolhemselever vid Västmanlands sinnesslöanstalt å Sofielund, 1897-1906

Syftet med denna uppsats är att utforska hur resocialiserings- och uppfostrans-ideal av sinnesslöa fungerade vid Västmanlands sinnesslöanstalt å Sofielund. Studien är en fallstudie med individfokus, som följer 18 intagna skolhemsele-ver vid sinnesslöanstalten i Sofielund. Det material som har använts är bland annat intagningslistor, journaler och personliga akter för de 18 undersöknings-personerna, som finns tillgängliga hos Landstingsarkivet Västmanland. Av denna undersökning framkommer bland annat att de 18 undersökningsperso-nerna kom från relativt normala familjer och hemförhållanden, som i de flesta fallen tillhörde arbetarklassen. Samtliga undersökningspersoner ansågs vara bildbara vid intagningen till Sofielund och den största delen av dem ansågs före intagningen lida av lättare sinnesslöhet (idioti). Dessutom ansågs inte någon av dem vara farlig för sin omgivning. Skolpersonalens beskrivningar stödjer inte heller uppfattningen om att de skulle ha ansetts vara farliga. Om de 18 undersökningspersonerna framkommer att de i vissa fall inte ansågs vara bildbara av skolledningen, tidigare utlåtanden till trots. Följaktligen visar resultatet på att en stor del av undersökningspersonerna blev hemskickade efter utskrivning från skolhemmet, möjligen för att de ansågs vara bildbara och därmed inte var lämpliga i skolhemmet. Denna studies resultat pekar också på att uppföljningen av undersökningspersonerna var relativt systema-tisk. En sammanfattande slutsats i denna studie är också att det inte var ovanligt att undersökningspersonerna skickades hem, trots att de flesta gjorde ganska små framsteg i skolan.

Vilhelm Ekelund och det litterära fältet 1897-1949

Vilhelm Ekelunds och det litterära fältet 1897-1949 [Vilhelm Ekelund and the literary field 1897-1949] The theoretical background of this study is Pierre Bourdieu’s sociological approach to literature. I use his theory concerning the importance of cultural (and other forms of symbolic) capital for the individual artist – and his description of the literary field as a place characterized by continuous conflict between different categories of participants. In the article, I argue that as a young poet, Ekelund held a position in the field that was with the intellectual group as opposed to the group of commercial authors – and among the young avant-garde as opposed to among the consecrated and well-established writers. However, this position changed somewhat during the years Ekelund spent in exile (1908-1921), and it continued to change after his return to Sweden. His reputation as a thoroughly intellectual writer was accentuated and, as time passed, he himself became a consecrated artist with certain privileges – e.g. grants and awards – to defend.
