Tidskriftsartikel (refereegranskat)abstract
- The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since 2014 July. This paper describes the second data release from this phase, and the 14th from SDSS overall (making this Data Release Fourteen or DR14). This release makes the data taken by SDSS-IV in its first two years of operation (2014-2016 July) public. Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey; the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data-driven machine-learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from the SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS web site (www.sdss.org) has been updated for this release and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020 and will be followed by SDSS-V.

Tidskriftsartikel (refereegranskat)abstract
- Background: Patients in prehospital care, irrespective of diseases or trauma might experience thermal discomfort because of a cold environment and are at risk for decreasing body temperature which can increase both morbidity and mortality.Objective: To explore patients' experiences of being cold when injured in a cold environment.Method: Twenty persons who had been injured in a cold environment in northern Sweden were interviewed. Active heat supply was given to 13 of them and seven had passive heat supply. The participants were asked to narrate their individual experience of cold and the pre- and post-injury event, until arrival at the emergency department. The interviews were transcribed verbatim, then analyzed with qualitative content analysis.Results: Patients described that they suffered more from the cold than because of the pain from the injury. Patients who received active heat supply experienced it in a positive way. Two categories were formulated: Enduring suffering and Relief of suffering.Conclusion: Thermal discomfort became the largest problem independent of the severity of the injuries. We recommend the use of active heat supply to reduce the negative experiences of thermal discomfort when a person is injured in a cold environment.

Framtidsbilder för samhällsbyggnad
- 2006
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Framtidsbilder för samhällsbyggnad 2020De kommande 15 åren står institutionen för Bygg- och miljöteknik inför stora förändringar. Därför har institutionen initierat projektet Framtidsbilder 2020 där man engagerat en framtidspanel bestående av elva yngre disputerade forskare. Arbetet inleddes med ett breddgruppsmöte där 110 personer representerande institutionens personal och studenter deltog. Vid mötet identifierades ett antal trender och osäkra utvecklingar som påverkar framtiden inom samhällsbyggnadsområdet. Deltagarna bidrog också med idéer till en önskvärd utveckling, vilket har sammanställts och utgör grunden till en gemensam önskvärd framtid/vision för institutionen. Materialet från breddgruppsmötet har bearbetats av Framtidspanelen och resulterat i fyra scenarier som beskriver hur samhällsbyggnadsområdet kan se ut år 2020. Syftet med framtidsbilderna är att de ska vara vägledande för institutionens beslut och förhållningssätt under de kommande åren.Fyra scenarierTurning TorsoSamhället präglas av en ekonomi som är på uppgång, och av ett nytänkande och öppet samhälle. Materiell status och individualism är viktigt. Detta leder till en hög arbetsbelastning samt krav på exklusiva varor av hög kvali-tet. Det finns en stor medvetenhet om miljöpåverkan och klimatförändringar och lösningarna för att klara energiförsörjningen är innovativa.Eco-metropolenDet sveper en grön våg genom dagens samhälle. Under de senaste 15 åren har vi insett att jorden skall vara en bebolig plats även åt dem som kommer efter oss. Vi söker ständigt efter nya, mer förfinade metoder att tillvarata de resurser vi har. Samhället och individen är i balans. Ekonomin är god och vi är miljömedvetna, trygga och integrerade. Nytänkande premieras och icke- materialistiska värderingar står högt i kurs. Vi tänker individuellt, men agerar mer än gärna för kollektivets bästa. Utbildning är gratis TrädgårdsstadenEtt samhälle där vi lärt oss hantera stress, men känner oss otrygga och helst umgås i slutna sociala sammanhang. Vi bor enkelt inne i stan, eller gärna på landsbygden nära storstäderna. Minskade behov av högutbildade i samhället gör att vi har svårt att rekrytera studenter till teknikutbildningar. Det traditionella tankesättet leder till kulturkrockar med företag och personer från andra länder.Gated communitiesFörsämrad ekonomi och ökad egoism har lett fram till ett stressat, otryggt och segregerat samhälle. Accelererande klimatförändringar och ökad miljö-påverkan skrämmer oss, men trots det åtgärdar vi inte problemen, utan koncentrerar oss på konsekvenserna. Arbetslöshet i samhällsbyggnadssek-torn leder till sänkt status för samhällsbyggaren. Vi har därför svårt att rekrytera studenter, och även forskningen har låg status.

Sloan Digital Sky Survey IV : Mapping the Milky Way, Nearby Galaxies, and the Distant Universe
- 2017
-
Ingår i: Astronomical Journal. - : IOP Publishing Ltd. - 0004-6256 .- 1538-3881. ; 154:1

Tidskriftsartikel (refereegranskat)abstract
- We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and. high signal-to-noise ratios in the near-infrared. The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey is obtaining spatially resolved spectroscopy for thousands of nearby galaxies (median z similar to 0.03). The extended Baryon Oscillation Spectroscopic Survey (eBOSS) is mapping the galaxy, quasar, and neutral gas distributions between z similar to 0.6 and 3.5 to constrain cosmology using baryon acoustic oscillations, redshift space distortions, and the shape of the power spectrum. Within eBOSS, we are conducting two major subprograms: the SPectroscopic IDentification of eROSITA Sources (SPIDERS), investigating X-ray AGNs. and galaxies in X-ray clusters, and the Time Domain Spectroscopic Survey (TDSS), obtaining spectra of variable sources. All programs use the 2.5 m Sloan Foundation Telescope at the. Apache Point Observatory; observations there began in Summer 2014. APOGEE-2 also operates a second near-infrared spectrograph at the 2.5 m du Pont Telescope at Las Campanas Observatory, with observations beginning in early 2017. Observations at both facilities are scheduled to continue through 2020. In keeping with previous SDSS policy, SDSS-IV provides regularly scheduled public data releases; the first one, Data Release 13, was made available in 2016 July.

A Multivariate Screening Strategy for Investigating Metabolic Effects of Strenuous Physical Exercise in Human Serum
- 2007

Tidskriftsartikel (refereegranskat)abstract
- A novel hypothesis-free multivariate screening methodology for the study of human exercise metabolism in blood serum is presented. Serum gas chromatography/time-of-flight mass spectrometry (GC/TOFMS) data was processed using hierarchical multivariate curve resolution (H-MCR), and orthogonal partial least-squares discriminant analysis (OPLS-DA) was used to model the systematic variation related to the acute effect of strenuous exercise. Potential metabolic biomarkers were identified using data base comparisons. Extensive validation was carried out including predictive H-MCR, 7-fold full cross-validation, and predictions for the OPLS-DA model, variable permutation for highlighting interesting metabolites, and pairwise t tests for examining the significance of metabolites. The concentration changes of potential biomarkers were verified in the raw GC/TOFMS data. In total, 420 potential metabolites were resolved in the serum samples. On the basis of the relative concentrations of the 420 resolved metabolites, a valid multivariate model for the difference between pre- and post-exercise subjects was obtained. A total of 34 metabolites were highlighted as potential biomarkers, all statistically significant (p < 8.1E-05). As an example, two potential markers were identified as glycerol and asparagine. The concentration changes for these two metabolites were also verified in the raw GC/TOFMS data.The strategy was shown to facilitate interpretation and validation of metabolic interactions in human serum as well as revealing the identity of potential markers for known or novel mechanisms of human exercise physiology. The multivariate way of addressing metabolism studies can help to increase the understanding of the integrative biology behind, as well as unravel new mechanistic explanations in relation to, exercise physiology.

Kaj Anderssons Morgonbris : kvinnopress, trettiotal och längtan efter fri tid
- 2007
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In the 1930s the Swedish homes were modernized through a series of social reforms. As a result of this, time was expected to be released from the housewife’s daily domestic duties and the question was what to do with this time. In this dissertation the concept of time is used in the sense of free time as time for free thinking. The time issue during the thirties is an underlying question throughout the study. The magazine Morgonbris (1904-), a political campaign journal published by the social democratic women’s association (in Swedish: Socialdemokratiska kvinnoförbundet, SSKF) was the public arena for political issues of this kind.The aim of the study is to scrutinize the magazine, its shape (typography and layout) and content, the editors´ journalism as well as the relationship to the SSKF and the circle of readers during the decade, in order to describe the dramatic changes of this political and public arena with special focus on the editorship of Kaj Andersson (1931-1936).Methodologically this study draws on Hannah Arendt’s “storytelling” or “fragmented historiography”. Theoretically the concepts “public sphere” and “proletarian experiences” are adopted and Jürgen Habermas, Oscar Negt & Alexander Kluge as well as Pierre Bourdieu, are referred to. The gender perspectives of Joan F. Scott and Yvonne Hirdman are also adopted.Kaj Andersson’s ”active journalism” in Morgonbris exhibits two distinguishing characteristics during the thirties, it was clearly socialist and critical towards nazism and fascism and it was the most salient vehicle of modernity within the Swedish press at the time. She re-styled the magazine, gave it a new outfit and introduced a new kind of modern, photojournalism. The result was an economic upswing for the magazine. The heritage of Ellen Key´s aesthetics came forward in a consumer campaign, “The best of the industry to the needs of the homes” (Fabrikernas bästa till hemmens behov), which bears similarities to the “Better Homes of America” campaign, launched in the 1920s in the USA. The political path in both campaigns coincided partly with the agenda of Alva Myrdal. Also the “Housewife Holiday” campaign that Kaj Andersson initiated in Morgonbris was in line with the modernization of women’s life throughout the country. The exhausted housewives’ yearning for rest and temporary release from domestic duties was reflected in several articles, in which their grass-root initiatives were acknowledged as political action.Until Kaj Anderson left Morgonbris, after several schisms with the committee about her creative – her backbiters would say self-indulgent – style to run the editorial office, she balanced on the border between commercialism and socialism. Her background in the party press, the social democratic newspaper Social Demokraten, influenced her ideas, but her initiatives to turn to the fields of production and consumption also drove a wedge into the field of journalism, as an involuntary beginning to separate it from the field of politics.

Systerskapets logiker : en etnologisk studie av feministiska fanzines
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis coheres around the issue of collective political mobilisation within one part of the contemporary feminist movement, or more specifically, within the Swedish feminist zine community. A feminist zine, also commonly referred to as Grrrlzine or femizine, is a small non-commercial and non-professional publication, which is distributed by channels other than that of the mainstream media.The aim of the thesis is to examine what role the 'name' ' sisterhood' has in the constitution of a feminist zine community. Further, it is to explore the ways in which this 'name' is expressed and the precise function this name has within the community itself. That 'sisterhood' is necessary for a feminist politics is, according to the vast majority of the zines studied, obvious. Nevertheless the issue of what sisterhood 'is' or what it ’ought to be’ is constantly under negotiation. In this thesis I study how the name sisterhood works to create a collective feminist identity – even if this very 'name' comes to be articulated in, sometimes radically, different forms.In order to conduct my analysis, I have taken several theoretical decisions. First, I have chosen to frame the zine community in accordance with the term communitas, defined as a collective identity constituted in terms of its opposites, by that which it is not. In this specific case, this Other consists of the commercial media, that is also, conceived as an effect of a wider patriarchal threat.Second, to understand the differences which exist within this community, I have chosen to develop three feminist logics, to capture some quite contradictory articulatory strategies. They are referred to as ’liberal feminist’, ’radical feminist’ and ’post feminist’. The concept of logics allows me to interpret how it is that three different (and sometimes competing) feminist traditions can be found in the zine community, and commonly how in a single zine, or a single text, the three logics can coalsce.As mentioned above, it is the 'name' sisterhood that provides the glue that holds the feminist zine community together. To understand this I have analyzed sisterhood by way of the concept 'empty signifier', that is, a 'name' which is partially emptied of meaning and which serves as a surface of inscription for a variety of feminist demands, demands that in themselves may have very little, or even nothing in common.Finally, the ideas outlined in the thesis call for reflexivity, that is, for an explicit meta-analysis of the conduct of one’s own research process. In this thesis I discuss the problematic arising when the feminist researcher studies a feminist movement, and the inevitable blurring of political partisanship and theoretical analysis that takes place. Here I pay particular attention to the frontiers that a political community is always-already in a process of re-negotiating, and how the researcher is herself part of this very re-negotiation.

Protection against cold : a survey of available equipment in Swedish pre-hospital services
- 2017
-
Ingår i: Acta Anaesthesiologica Scandinavica. - : John Wiley & Sons. - 0001-5172 .- 1399-6576. ; 61:10, s. 1354-1360

Tidskriftsartikel (refereegranskat)abstract
- Background: The aim of this study was to survey the current equipment used for prevention, treatment and monitoring of accidental hypothermia in Swedish pre-hospital services.Methods: A questionnaire was sent to all road ambulance services (AS), the helicopter emergency medical services (HEMS), the national helicopter search and rescue service (SAR) and the municipal rescue services (RS) in Sweden to determine the availability of insulation, active warming, fluid heating, and low-reading thermometers.Results: The response rate was 77% (n = 255). All units carried woollen or polyester blankets for basic insulation. Specific windproof insulation materials were common in the HEMS, SAR and RS units but only present in about half of the AS units. Active warming equipment was present in all the SAR units, but only in about two-thirds of the HEMS units and about one-third of the AS units. About half of the RS units had the ability to provide a heated tent or container. Low-reading thermometers were present in less than half of the AS and HEMS units and were non-existent in the SAR units. Pre-warmed intravenous fluids were carried by almost all of the AS units and half of the HEMS units but infusion heaters were absent in most units.Conclusion: Basic insulation capabilities are well established in the Swedish pre-hospital services. Specific wind and waterproof insulation materials, active warming devices, low-reading thermometers and IV fluid heating systems are less common. We suggest the development and implementation of national guidelines on accidental hypothermia that include basic recommendations on equipment requirements.

SDSS-IV from 2014 to 2016 : A Detailed Demographic Comparison over Three Years
- 2023
-
Ingår i: Publications of the Astronomical Society of the Pacific. - 0004-6280. ; 135:1054

Tidskriftsartikel (refereegranskat)abstract
- The Sloan Digital Sky Survey (SDSS) is one of the largest international astronomy organizations. We present demographic data based on surveys of its members from 2014, 2015 and 2016, during the fourth phase of SDSS (SDSS-IV). We find about half of SDSS-IV collaboration members were based in North America, a quarter in Europe, and the remainder in Asia and Central and South America. Overall, 26%-36% are women (from 2014 to 2016), up to 2% report non-binary genders. 11%-14% report that they are racial or ethnic minorities where they live. The fraction of women drops with seniority, and is also lower among collaboration leadership. Men in SDSS-IV were more likely to report being in a leadership role, and for the role to be funded and formally recognized. SDSS-IV collaboration members are twice as likely to have a parent with a college degree, than the general population, and are ten times more likely to have a parent with a PhD. This trend is slightly enhanced for female collaboration members. Despite this, the fraction of first generation college students is significant (31%). This fraction increased among collaboration members who are racial or ethnic minorities (40%-50%), and decreased among women (15%-25%). SDSS-IV implemented many inclusive policies and established a dedicated committee, the Committee on INclusiveness in SDSS. More than 60% of the collaboration agree that the collaboration is inclusive; however, collaboration leadership more strongly agree with this than the general membership. In this paper, we explain these results in full, including the history of inclusive efforts in SDSS-IV. We conclude with a list of suggested recommendations based on our findings, which can be used to improve equity and inclusion in large astronomical collaborations, which we argue is not only moral, but will also optimize their scientific output.
