Rolf Edberg : A study of the authorship of an environment philosopher
No full textIn this essay I have tried to present the ideas and thoughts of the Swedish author Rolf Edberg (1912-1997), journalist, ambassador and county governor. By many regarded as an environment philosopher and the introducer of deep ecology into Sweden. The essay emphasizes Edberg as a modern renaissance man of important knowledge with a rhetorical force to present and generalize the problems the planet Earth is meeting. The paper compares him with Henry Thoreau but also finds a close but perhaps unintended relationship with the German philosopher Ernst Haeckel although Edberg himself claimed to be a Darwinist at heart. The essay stresses on four characteristic features in his authorship namely 1) a holistic view of nature and man, rejecting dualism for monism; 2) a cosmic relationship within the whole universe and also between organic and inorganic matter; 3) the planet Earth is in a crisis due to an uneven and unjust distribution of the resources of the Earth, the nuclear weapon threat and the overpopulation; 4) the evolution and not the religion has the answer to our existential questions

Background: Hypercholesterolemia is a major risk factor for cardiovascular disease and the number one cause of death among women in Western countries. Declining levels of estrogen at menopause could be a contribution factor. Isoflavones is a vegetable substance, with structural and functional similarities to the human estrogen. This is a potential reason for possible cholesterol-lowering effects. The substrate of studies on isoflavones and its effect on cholesterol found today is ambiguous and there are uncertainties about which statements can be made.
Objective: To examine the scientific evidence on whether isoflavones in combination with isoflavones have a different impact on HDL- and LDL-cholesterol in hypercholesterolemic postmenopausal women in comparison with milk protein.
Search strategy: Literature searches were made in the databases PubMed and Scopus. Search words used were of relevance for the research question of this systematic review.
Selection criteria: Randomized controlled trials done on postmenopausal women were included. They compared isoflavones combined with soy protein with milk protein and were preformed on women with elevated levels of total- and /or LDL-cholesterol. Studies conducted on populations with hormone – and/or cholesterol -lowering therapy were excluded.
Data collection and analysis: The literature search yielded three RCTs which were validated using SBUs Granskningsmall för randomiserade kontrollerade studier. The strength of evidence for the included studies was then weighed together with Göteborgs universitets sammanfattande evidensformulär.
Main results: Two of the studies were estimated to have a mediate-high study quality and the third was judged to have a mediate-high to high study quality. The summarized grade of evidence for the selected outcome measures were considered mediate-high. Only one study found a significant difference in LDL-cholesterol between intervention- and control group. None of the studies showed a significant difference in HDL cholesterol.
Conclusions: There is moderate evidence that isoflavones in combination with soy protein does not provide any significant difference in impact on HDL-cholesterol compared with milk protein, in hypercholesterolemic postmenopausal women. As the effect on LDL-cholesterol differs between the included studies no conclusions can be drawn. The scientific substrate with estimated moderate evidence shows an ambiguous result for the outcome measure LDL-cholesterol. Though the result indicates that higher levels of naturally occurring isoflavones could potentially provide a greater reduction compared with milk protein.Sahlgrenska Akademin vid Göteborgs universitet

Bakgrund: Hyperkolesterolemi är en betydande riskfaktor för kardiovaskulära sjukdomar, vilket är den främsta dödsorsaken bland kvinnor i västerländska länder. Sjunkande nivåer av östrogen vid menopaus kan vara en bidragande orsak. Isoflavonoider är ett vegetabiliskt ämne med östrogenlikande egenskaper, detta är en potentiell orsak till dess eventuella kolesterolsänkande effekt. Underlaget av studier på isoflavonoiders effekt på kolesterol är i dagsläget tvetydligt och det finns en osäkerheten kring vad man egentligen kan uttala sig om.
Syfte: Att undersöka det vetenskapliga underlaget för huruvida isoflavonoider i kombination med sojaprotein har en skiljd inverkan på HDL- samt LDL-kolesterol hos postmenopausala kvinnor med hyperkolesterolemi jämfört med mjölkprotein.
Sökväg: Litteratursökningar gjordes i databaserna PubMed och Scopus. De sökord som användes var av relevans för översiktsartikelns frågeställning.
Urvalskriterier: Randomiserade kontrollerade studier, gjorda på postmenopausala kvinnor inkluderades. De jämförde isoflavonoider i kombination med sojaprotein med mjölkprotein och var gjorda på kvinnor med förhöjda total- och/eller LDL-kolesterolvärden. Studier gjorda på populationer med hormon- och/eller kolesterolsänkande behandling exkluderades.
Datainsamling och analys: Litteratursökningen gav tre RCT-studier som granskades med hjälp av SBU:s Granskningsmall för randomiserade kontrollerade studier. De inkluderade studiernas evidensstyrka vägdes sedan samman med Göteborgs universitets sammanfattande evidensformulär.
Resultat: Två av studierna skattades till en medelhög studiekvalitet och den tredje bedömdes ha en medelhög till hög studiekvalitet. Den sammanlagda evidensstyrkan för valda effektmått bedömdes vara måttlig. Enbart en studie visade en signifikant skillnad i LDL-kolesterol mellan intervention- och kontrollgrupp. Inte någon av studierna visade på en signifikant skillnad i HDL-kolesterol.
Slutsats: Det finns måttlig evidens för att isoflavonoider i kombination med sojaprotein ej ger någon signifikant skillnad i påverkan på HDL-kolesterol i jämförelse med mjölkprotein, hos postmenopausala kvinnor med hyperkolesterolemi. Det vetenskapliga underlaget med uppskattad måttlig evidens, ger ett tvetydligt resultat för utfallsmåttet LDL-kolesterol. Resultatet tyder dock på att intag av högre halter naturligt förekommande isoflavonoider eventuellt kan ge en större sänkning jämfört med mjölkprotein
Creative Writing for Critical Thinking
No full textThis book explores narrative imagination and emotion as resources for learning critical meta-reflection. The author examines the learning trajectories of several students as they engage in learning to think critically through a new approach to creative writing, and details how learning through writing is linked to new discoursal identities which are trialled in the writing process. In doing so, she analyses the processes of expansion and change that result from the negotiations involved in learning through writing. This volume offers a completely new approach to creative writing, including useful practical advice as well as a solid theoretical base. It is sure to appeal to students of creative writing and discourse analysis as well as applied linguistics and language as identity.</p
Structured ionospheric outflow during the Cassini T55–T59 Titan flybys
No full textDuring the final three of the five consecutive and similar Cassini Titan flybys T55–T59 we observe a region characterized by high plasma densities (electron densities of 1–8 cm3 ) in the tail/nightside of Titan. This region is observed progressively farther downtail from pass to pass and is interpreted as a plume of ionospheric plasma escaping Titan, which appears steady in both location and time. The ions
in this plasma plume are moving in the direction away from Titan and are a mixture of both light and heavy ions with composition revealing that their origin are in Titan’s ionosphere, while the electrons are more isotropically distributed. Magnetic field measurements indicate the presence of a current sheet at the inner edge of this region. We discuss the mechanisms behind this outflow, and suggest that it could be caused by ambipolar diffusion, magnetic moment pumping or dispersive Alfve´n waves.Fil: Edberg, N. J. T..

Magnetic field measurements during the ROSETTA flyby at asteroid (21) Lutetia
No full textOn July 10, 2010, the ROSETTA spacecraft performed a flyby at asteroid (21) Lutetia at a solar distance of 2.72 AU. The spacecraft�asteroid distance at closest approach was 3120 km. The magnetometers onboard ROSETTA were operating but did not detect any conclusive signature of the asteroid. Any magnetic field signature which could possibly be attributed to the asteroid was below 1nT. Consequently an upper limit for the global magnetic properties of asteroid (21) Lutetia could be derived: maximum dipole moment r1:0 1012 Am2, global maximum magnetization r2:1 103 A=m, specific moment r5:9 107 Am2=kg. Draping of magnetic fields around the nucleus was sought, but evidence for this could not be clearly identified in the data. Plasma simulations taking into account the estimated upper limit of the magnetization and possible outgassing revealed interesting structures very close to the asteroid.The results obtained at Lutetia are contrasted with the results of other
asteroid fly by results
Stationary flux ropes at the southern terminator of Mars
No full textFlux ropes have long been observed in the upper atmosphere of Venus, and more recently at Mars. Here we present magnetic field measurements of flux ropes encountered at the southern terminator of Mars by Mars Global Surveyor, and compare them to a flux rope model. This allows several parameters of each rope to be inferred. Remarkably similar flux ropes are met repeatedly at the southern terminator over a period of the Martian year, when strong crustal magnetic fields are upstream of their position, indicating that they are most likely stationary and attached to the upstream crustal fields. A mechanism is described that could produce the observed flux ropes
Corotating interaction regions as seen by the STEREO Heliospheric Imagers 2007 – 2010
No full textT.M. Conlon and A.O. Williams were supported by an STFC, UK studentship and S.E. Milan was supported by STFC grant ST/K001000/1. Date of Acceptance: 08/08/2015NASA’s Solar Terrestrial Relations Observatory (STEREO) mission has coincided with a pronounced solar minimum. This allowed for easier detection of corotating interaction regions (CIRs). CIRs are formed by the interaction between fast and slow solar-wind streams ejected from source regions on the solar surface that rotate with the Sun. High-density plasma blobs that have become entrained at the stream interface can be tracked out to large elongations in data from the Heliospheric Imager (HI) instruments onboard STEREO. These blobs act as tracers of the CIR itself such that their HI signatures can be used to estimate CIR source location and radial speed. We estimate the kinematic properties of solar-wind transients associated with 40 CIRs detected by the HI instrument onboard the STEREO-A spacecraft between 2007 and 2010. We identify in-situ signatures of these transients at L1 using the Advanced Composition Explorer (ACE) and compare the in-situ parameters with the HI results. We note that solar-wind transients associated with CIRs appear to travel at or close to the slow solar-wind speed preceding the event as measured in situ. We also highlight limitations in the commonly used analysis techniques of solar-wind transients by considering variability in the solar wind.Peer reviewe
Improved Information Transfer in Elderly Care : - a case study of implementation of a modified SBAR tool
No full textBrister i kommunikation är den enskilt största orsaken till att avvikelser inträffar i hälso-och sjukvård. Genom att standardisera kommunikation och informationsöverföring minskar variationen, och logik och ömsesidig överenskommelse skapas. Syftet med förbättringsarbetet var att öka patientsäkerheten genom att förenkla kommunikationen inom teamet på ett vård-och omsorgboende, genom att införa kommunikationsverktyget SBAR. Den efterföljande studien syftade till att undersöka hur SBAR upplevs inom äldreomsorgen, och vad som kan vara framgångsfaktorer och fallgropar vid införande. Action research har tillämpats och en innehållsanalys har utförts efter fokusgruppsintervjuer. Verksamheten såg en positiv utveckling av förbättrad informationsöverföring men nådde inte upp till de uppsatta målen. SBAR upplevdes användbart när de professionella hade fått praktisk träning. De professionella kände en ökad trygghet då den muntliga rapporteringen kombinerades med skriftlig rapportering. Projektet skapade gemensamt lärande genom deltagande observationer. Projektet gjorde att de omgivande strukturerna blev tydligare för personalgruppen och informationsöverföringens fokus lyftes från individnivå till systemnivå. SBAR-strukturen förenklades något för att passa bättre i den flerspråkiga kontexten. Nya områden för förbättring identifierades och en aktivitetstavla skapades. Att hålla jämn utbildningstakt och utbilda vikarier var en utmaning i projektet. Lack of communication is the single biggest reason for errors in healthcare. By standardizing the communication, the variation is reduced and logic and mutual agreement are created. The purpose of the improvement work was to increase patient safety by simplifying communication by introducing the SBAR communication tool. The subsequent study aimed to investigate how SBAR was experienced in the elderly care team, and to describe success factors and difficulties at the time of implementation. The author was inspired by action research. A content analysis has been applied on the data collected. There was an improvement in the information transfer, but the unit did not reach the set targets. SBAR was found useful by the professionals after practical training. The professionals felt greater security with a combination of oral and written report. The project created common learning through participatory observations and by clarifying the surrounding structures for the professionals. The project contributed to changed focus from an individual to a system level concerning the information process. The SBAR structure was slightly simplified to fit the multilingual context. New areas for improvement were identified and an activity board for the elderly was created. Keeping consistent education and training temporary staff was a challenge
