    Sex in an Evolutionary Perspective: Just Another Reaction Norm2010In: Evolutionary biology, ISSN 0071-3260, E-ISSN 1934-2845, Vol. 37, no 4, p. 234-246Article, review/survey (Refereed)
    Abstract [en]

    It is common to refer to all sorts of clear-cut differences between the sexes as something that is biologically almost inevitable. Although this does not reflect the status of evolutionary theory on sex determination and sexual dimorphism, it is probably a common view among evolutionary biologists as well, because of the impact of sexual selection theory. To get away from thinking about biological sex and traits associated with a particular sex as something static, it should be recognized that in an evolutionary perspective sex can be viewed as a reaction norm, with sex attributes being phenotypically plastic. Sex determination itself is fundamentally plastic, even when it is termed "genetic". The phenotypic expression of traits that are statistically associated with a particular sex always has a plastic component. This plasticity allows for much more variation in the expression of traits according to sex and more overlap between the sexes than is typically acknowledged. Here we review the variation and frequency of evolutionary changes in sex, sex determination and sex roles and conclude that sex in an evolutionary time-frame is extremely variable. We draw on recent findings in sex determination mechanisms, empirical findings of morphology and behaviour as well as genetic and developmental models to explore the concept of sex as a reaction norm. From this point of view, sexual differences are not expected to generally fall into neat, discrete, pre-determined classes. It is important to acknowledge this variability in order to increase objectivity in evolutionary research.

    From feminism to FemInc.ism: On the uneasy relationship between feminism, entrepreneurship and the Nordic welfare state2016In: The International Entrepreneurship and Management Journal, ISSN 1554-7191, E-ISSN 1555-1938, Vol. 12, no 2, p. 369-392Article in journal (Refereed)
    Abstract [en]

    Feminism in the Nordic countries was primarily formulated in terms of ‘state feminism’. The women’s movement cooperated with feminist government officials and politicians, resulting in societies that can be considered to be the most gender-equal societies in the world. Historically, the state provided for a large publicly-financed welfare sector which made it possible for many women to combine work and family through the state’s implementation of family-friendly policies, while simultaneously providing employment opportunities for many women. However, since the financial crisis of the 1990s, there has been a political change influenced by neo-liberal thought, in which politicians have handed over the welfare state’s responsibilities to the market, and, instead, the politicians have encouraged entrepreneurship, not least among women. Further to this development, there has been a change in emphasis from entrepreneurship (understood as starting and running a business) to entrepreneurialism which, in addition to a belief in the efficacy of market forces, also contains a social dimension where individuals are supposed to be flexible and exercise choice. In this article, we ask whether this entails a change in the feminist project in the Nordic countries, and if so, what the likely consequences are for this project, both in practice and in research. In order to answer this question, we reviewed existing Nordic research on women’s entrepreneurship and examined how this body of work conceptualizes entrepreneurship, gender, the state, and equality. We also considered whether any trends could be identified. We relate our findings to recent changes in government policy and conclude that the current discourse on entrepreneurship challenges, and possibly weakens, state feminism, but we also conclude that this discourse may also provide space for new forms of feminist action, in market terms. We coin the term FemInc.ism to denote feminist action through enterprise and we discuss a number of important challenges that research on this phenomenon is faced with.

    Metabolic engineering of starch synthesis in barley2001Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Starch is an important industrial raw material both for food and non-food purposes. In plants, starch is deposited in the leaf and in the storage tissues such as seed endosperm, roots or tubers. Starch is a glucose polymer, and its synthesis involves four groups of enzymes, ADP-glucose-pyrophosphorylase (AGPase), starch synthases (SS), starch branching enzymes (SBE), and starch debranching enzymes (DBE). In barley, four isoforms of SBE have been identified and the temporal and spatial expression of their genes (sbe) has been studied in our lab.

    The long-term objective of our research is to produce novel starches in planta for industrial applications. This requires the transformation of barley in order to produce transgenic plants with altered activity for one or more sbe genes. Using a plant-optimized version of Green Fluorescent Protein (GFP) as the only marker we produced a transgenic Nordic elite cultivar of barley in 1999. The usefulness of GFP as a marker has also been applied in various transient experiments and for this reason a set of monocotyledonous expression vectors has been developed. Using these vectors, the spatial expression pattern of the sbeII genes has been investigated.

    The sbeIIa and sbeIIb genes are differentially transcribed during barley seed development. The sbeIIb gene is expressed exclusively in the endosperm while the sbeIIa gene is expressed also in embryonic and vegetative tissues. The tissue specific regulation of the sbeII genes was hown to be executed via a repressor protein acting on a cis element located in the second intron of the sbeIIb gene. We also suggest that the repression is controlled by the local sugar concentration in the barley seed endosperm.

    Musikdirektör Anders Sidner: Musikundervisning och musikliv i skolstaden Härnösand 1840-18701998Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The present study, together with my licentiate's dissertation, Music education and examination at the Royal Academy of Music during "the Pehr Frigel Era", 1796-1842, constitutes my doctoral dissertation. In the chapter Preludes, the relation between the two studies is accounted for.

    The study deals with Anders Sidner's work and career, and his influence on the teaching of music and music life in Härnösand. In my licentiate's dissertation I examined the music education and examination at the Royal Academy of Music during the first half of the nineteenth century. I pointed out, from a cultural-theoretical perspective, that the work of the Academy probably promoted cultural solidarity in a socially developing manner. Anders Sidner was one of around eighty graduates who were examined during this period. The aim of this study is to map out and critically examine Sidner's work and career in Härnösand, as well as to observe what effects his work has had.

    The structure of the study is mainly chronological. The understanding of Sidner's work, ideas and actions is based to a great extent on the knowledge of his personal situation and living conditions.

    Sidner's music studies, which were pursued parallel with his academic studies at Uppsala, are characterised by self-tuition, learning from friends and active participation in choirs and orchestras.

    After his academic studies at Uppsala and the graduation from the Royal Academy of Music, Sidner worked in Härnösand for twenty-eight years as a music teacher at grammar school and teacher training college. In both types of education, choir singing was an important part of the teaching. Sidner took the initiative in founding a musical society, and was its leader for a number of years. In the 1860s he initiated a collaboration between the musical society and a great number of the town's young male and female musicians. Sidner also engaged young female instrumentalists in the student orchestra. Both these initiatives can be considered unique.

    In relation to the town population, a remarkably great number of people attended the wide variety of musical events. The fact that the school's spacious music hall was used as a concert hall and that the music teacher as well as a number of other teachers were active in the local music life probably contributed to the active participation of many young people.

    The examination of Anders Sidner's teaching methods and his ideas on musical-aesthetic issues shows that his work was in line with the widely spread values of his time.

    My study indicates that Sidner's contribution to the teaching of music and music life in Härnösand promoted an increasing cultural solidarity. It is evident that his work also was to form part of a continuous process of secularisation. The music life in school was integrated with non-ecclesiastical activities to an ever increasing extent.

    Determining the effects of duration and recency of exposure to environmental enrichment2016In: Applied Animal Behaviour Science, ISSN 0168-1591, E-ISSN 1872-9045, Vol. 176, p. 163-169Article in journal (Refereed)
    Abstract [en]

    Experience can help animals adapt their behaviour to fit the environment or conditions that they find themselves in. Understanding how and when experience affects behaviour is important for the animals we rear in captivity. This is particularly true when we rear animals with the intent of releasing them into the wild as part of population rehabilitation and conservation efforts. We investigated how exposure to a changing, more complex environment promotes behavioural development in juvenile trout. Four groups of fish were compared; (i) fish that were maintained without enrichment, (ii) fish that were exposed to an early period of enrichment, but were then returned to a plain environment, (iii) fish that were maintained in plain conditions, but were then exposed to enrichment towards the end of the rearing phase, (iv) a group that were kept in enriched conditions throughout the 12 week rearing period. We then assessed fish anxiety levels, their spatial learning ability, and the capacity of the fish to find their way through a barrier where different routes were presented across 4 different trials. Fish that experienced enriched conditions for the longest duration had superior spatial learning abilities, and they were better at finding the correct route to get past the barrier than fish from the remaining three treatments. Positive effects on behaviour were, however, also found in the fish that only experienced enrichment in the last part of the rearing period, compared to the control, or fish exposed to early enrichment. No effect of enrichment was found on levels of anxiety in any of the groups.

    Living in a predation matrix: Studies on fish and their prey in a Baltic Sea coastal area2012Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis was written within the framework of a biomanipulation project where young-of-the-year (YOY) pikeperch (Sander lucioperca) were stocked to a Baltic Sea bay to improve water quality through a top-down trophic cascade. The aim of my doctorial studies was however focused on a broader ecological question, namely predation (the main driving force in a biomanipulation). Hence, this thesis consists of four papers where we study the interactions between predator and prey using fish and zooplankton and how these interactions can be measured.

    In paper I we evaluated the performance of different diet analysis methods by individual based modelling and found that when having a nutritional gain perspective, mass based methods described diets best. Paper II investigated how the explorative, foraging and anti-predator behaviour of the YOY pikeperch used for stocking were affected by their rearing environment (pond vs. tank rearing). The more complex and varied environment in the semi-natural ponds seemed to promote a more flexible and active behaviour, better equipping young fish for survival in the wild. For paper III we studied the diel vertical migration in the six copepodite stages of the zooplankton Acartia spp. and Eurytemora affinis in relation to fish biomass, phytoplankton abundance and temperature. Both species migrated and in addition showed increased migration range with size within species, indicating evasion from visual predators. Paper IV addressed the movement of littoral Eurasian perch (Perca fluviatilis) via stable isotope signatures (13C and 15N) and body condition. We found clear indications of sedentarity and intra-habitat dietary differences. Interactions between predators and prey are complex and affected by both physiological and environmental characteristics as well as behavioural traits. The results in this thesis suggest that different species and even different life stages pursue different strategies to survive.

    Evaluating fish diet analysis methods by individual-based modelling2012In: Canadian Journal of Fisheries and Aquatic Sciences, ISSN 0706-652X, E-ISSN 1205-7533, Vol. 69, no 7, p. 1184-1201Article in journal (Refereed)
    Abstract [en]

    Knowledge of diet compositions is important in ecological research. There are many methods available and numerous aspects of diet composition. Here we used modelling to evaluate how well different diet analysis methods describe the true diet of fish, expressed in mass percentages. The methods studied were both basic methods (frequency of occurrence, dominance, numeric, mass, points) and composite indices (Index of Relative Importance, Comparative Feeding Index). Analyses were based on both averaged stomach content of individual fish and on pooled content from several fish. Prey preference, prey size, and evacuation rate influenced the performance of the diet analysis methods. The basic methods performed better than composite indices. Mass and points methods produced diet compositions most similar to the true diet and were also most robust, indicating that these methods should be used to describe energetic-nutritional sources of fish.

    Rearing environment affect important life skills in pikeperch (Sander lucioperca)2012In: Boreal environment research, ISSN 1239-6095, E-ISSN 1797-2469, Vol. 17, no 3-4, p. 291-304Article in journal (Refereed)
    Abstract [en]

    The effect of rearing environment on the behaviour of young-of-the-year pikeperch (Sander lucioperca) bred at three different production facilities was investigated. Two groups were reared in semi-natural ponds and one group in indoor tanks. Exploratory, foraging and anti-predator behaviours were studied in aquarium experiments. There were no significant differences between pond- and tank-reared fish in reluctance to explore their new environment, but pond-reared fish spent significantly more time in macro-vegetation. Pond-reared fish were significantly faster to start foraging on live prey (Neomysis integer) that they had not encountered before. As compared with tank-reared fish, pond-reared fish were also significantly more active in their anti-predator response. Rearing environment obviously influences the development of important life skills. These differences may impact the success rate when stocking young-of-the-year pikeperch into natural waters.

    ESOPHAGEAL STRICTURE AFTER RADIOTHERAPY IN PATIENTS WITH HEAD AND NECK CANCER: EXPERIENCE OF A SINGLE INSTITUTION OVER 2 TREATMENT PERIODS2010In: Head and Neck, ISSN 1043-3074, E-ISSN 1097-0347, Vol. 32, no 4, p. 452-461Article in journal (Refereed)
    Abstract [en]

    Background. Risk factors for development of a stricture of the upper esophagus after radiotherapy for head and neck cancer are poorly defined. Methods. This was a retrospective case-control study of patients diagnosed and treated for esophageal stricture after radiotherapy for head and neck cancer. Results. The incidence of esophageal stricture after external beam radiation therapy (EBRT) was 3.3%. Seventy patients with stricture and 66 patients without stricture were identified. A multivariate analysis showed that there was increased risk of stricture in receiving enteral feeding during EBRT or in receiving a mean dose of >45 By to the upper esophagus. Conclusions. Enteral feeding during EBRT is strongly associated with the development of stricture of the esophagus, as is a mean dose of >45 Gy to the upper esophagus. Treatment of the stricture with Savary-Gilliard bougienage or through scope balloon dilatation is safe and successful but often has to be repeated.

    Abstract [en]

    In this paper we study noise sensitivity and threshold phenomena for Poisson Voronoi percolation on R-2. In the setting of Boolean functions, both threshold phenomena and noise sensitivity can be understood via the study of randomized algorithms. Together with a simple discretization argument, such techniques apply also to the continuum setting. Via the study of a suitable algorithm we show that box-crossing events in Voronoi percolation are noise sensitive and present a threshold phenomenon with polynomial window. We also study the effect of other kinds of perturbations, and emphasize the fact that the techniques we use apply for a broad range of models.

    Competing first passage percolation on random graphs with finite variance degrees2019In: Random structures & algorithms (Print), ISSN 1042-9832, E-ISSN 1098-2418, Vol. 55, no 3, p. 545-559Article in journal (Refereed)
    Abstract [en]

    We study the growth of two competing infection types on graphs generated by the configuration model with a given degree sequence. Starting from two vertices chosen uniformly at random, the infection types spread via the edges in the graph in that an uninfected vertex becomes type 1 (2) infected at rate lambda(1) (lambda(2)) times the number of nearest neighbors of type 1 (2). Assuming (essentially) that the degree of a randomly chosen vertex has finite second moment, we show that if lambda(1) = lambda(2), then the fraction of vertices that are ultimately infected by type 1 converges to a continuous random variable V is an element of (0,1), as the number of vertices tends to infinity. Both infection types hence occupy a positive (random) fraction of the vertices. If lambda(1) not equal lambda(2), on the other hand, then the type with the larger intensity occupies all but a vanishing fraction of the vertices. Our results apply also to a uniformly chosen simple graph with the given degree sequence.

    Abstract [en]

    We study survival among two competing types in two settings: a planar growth model related to two-neighbor bootstrap percolation, and a system of urns with graph-based interactions. In the planar growth model, uncolored sites are given a color at rate 0, 1 or infinity, depending on whether they have zero, one, or at least two neighbors of that color. In the urn scheme, each vertex of a graph G has an associated urn containing some number of either blue or red balls ( but not both). At each time step, a ball is chosen uniformly at random from all those currently present in the system, a ball of the same color is added to each neighboring urn, and balls in the same urn but of different colors annihilate on a one-for-one basis. We show that, for every connected graph G and every initial configuration, only one color survives almost surely. As a corollary, we deduce that in the two-type growth model on Z(2), one of the colors only infects a finite number of sites with probability one. We also discuss generalizations to higher dimensions and multi-type processes, and list a number of open problems and conjectures.

    Existence of an unbounded vacant set for subcritical continuum percolation2018In: Electronic Communications in Probability, ISSN 1083-589X, E-ISSN 1083-589X, Vol. 23, article id 63Article in journal (Refereed)
    Abstract [en]

    We consider the Poisson Boolean percolation model in R-2, where the radius of each ball is independently chosen according to some probability measure with finite second moment. For this model, we show that the two thresholds, for the existence of an unbounded occupied and an unbounded vacant component, coincide. This complements a recent study of the sharpness of the phase transition in Poisson Boolean percolation by the same authors. As a corollary it follows that for Poisson Boolean percolation in R-d, for any d >= 2, finite moment of order d is both necessary and sufficient for the existence of a nontrivial phase transition for the vacant set.

    Avkastningskrav på aktieplaceringar; vad är rimligt?2002Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Vi lever i ett kapitalistiskt system. hela detta system bygger på att avkastningen på det kapital som investerats i systemet skall räcka till att "föda" de personer som ingår i systemet. Investeringar i vår tid har alltmer börjat bli koncentrearade till aktiemarknaden. Härmed har aktievärderingarna skruvats upp mer och mer, och har till sist nått en nivå där den sannolika avkastningen för den som placerar på dessa höga nivåer blir mycket låg.

    Aktierekommendationer: -En Jämförande Analys2004Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna jämförande studie har varit att undersöka om någon fondkommissionär i vårt urval utfärdar bättre analyser och därmed har ett informationsövertag gentemot övriga, samt i vilken utsträckning det utfärdas sälj- respektive köprekommendationer. Vi har använt oss av olika modeller vilka vi konstruerat själva. Resultatet tyder på en positiv ”bias” då det utfärdas tre gånger fler köprekommendationer än säljrekommendationer. Uppsatsen visar

    LUKoil - ett värderingsproblem?2006Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    LUKoil är Rysslands största privata oljebolag. Det är många analytiker som följer bolaget, ger ut riktpriser och rekommendationer om huruvida man ska investera i aktien eller inte. På samma vis ger analytiker ut rekommendationer för västerländska oljebolag. Analytikerna sätter det riktpris de, för den tidpunkten, bedömer att aktien ska stå i om tolv månader. Men hur skiljer sig riktpriserna analytiker emellan, vår bedömning är att det är svårare att värdera LUKoils aktie i jämförelse med BP, Exxon och Shell. Vårt syfte är att undersöka om det råder en större oenighet bland analytikers aktievärdering av LUKoils aktie i jämförelse med BP, Shell och Exxon. Vidare har vi genom en nyckeltalsanalys av bolagen, rapporter från de olika analyshusen, litteratur och annan forskning försökt ge en förklaring till varför det är svårare att analysera LUKoil. Vårt tillvägagångssätt har varit att genom en statistisk undersökning se om analytikernas riktpriser skiljer sig mer vid värderingen av LUKoil än vid värderingen av BP, Exxon och Shell. Vi har i vår undersökning använt oss av rapporter från de större analyshusen daterade fem år tillbaka i tiden. Detta för att jämföra spridningen i deras riktpriser, samt identifiera vilka faktorer de tar hänsyn till när de analyserar de olika bolagen. Av vår statistiska analys kan vi se att det råder en signifikant skillnad, a = 0,05, mellan differensen i riktpriset från de olika analyshusen av LUKoil i jämförelse med BP, Exxon och Shell. Detta är en indikation på att det är svårare att värdera och bedöma LUKoils utveckling. I vår uppsats drar vi slutsatsen att det beror framförallt på den höga landsrisken i Ryssland. Landsrisken i Ryssland består framförallt av en hög valutarisk, högt och osäkert skattetryck samt en svag äganderätt. Vidare kan man se att bolaget är betydligt lägre värderat än de övriga bolagen, detta trots att de har den näst största oljereserven i världen samt den högsta återupptäckningsgraden. Detta förklaras av den höga risken som investerare ser i den ryska marknaden.

    Abstract [sv]

    Tribunalen har gjort fel igen, menar fackförbundet 3F som än en gång har överklagat Tribunalens dom i det mål där förbundet ifrågasätter danska statens stöd till fartyg som är registrerade i det danska internationella skeppsregistret. Därmed går målet in på sitt tionde år och sin andra runda i EU-domstolen.

    Abstract [en]

    1999 återupptogs försöken att skapa en reglering på EU-nivå av villkoren för arbetstagare som hyrs ut av bemanningsföretag, först genom förhandlingar mellan arbetsmarknadens parter ("social dialog"), och därefter genom den traditionella lagstiftningsproceduren med förhandlingar i ministerrådet utifrån ett direktivförslag utarbetat av kommissionen. Författaren rekonstruerar i detalj förloppen i den sociala dialogen och ministerrådet från 1999 till 2007, och analyserar varför båda misslyckades.

    Abstract [sv]

    Den blockad mot det tyska företaget Hekabe Design som Malernes Fagforening i Århus varslade om stred inte mot EU-rätten. Det slog den danska Arbejdsretten fast när den nyligen för första gången efter EU-domstolens dom i Lavalmålet prövade om en dansk fack-förening kunde vidta stridsåtgärder för att få ett utstationerande företag att teckna kollektiv-avtal. När målet avgjordes var arbetet redan avslutat, men domen har principiell betydelse för de flera hundra liknande krav som danska fack driver varje år.

I varje fall gav arbetsgivarorganisationerna den 2 april ett positivt svar på Europeiska kommissionens förfrågan.

    Efter en fnurra på tråden i våras då Europafacket sade nej till arbetsgivarorganisationerna BusinessEuropes, CEEP:s och Ueapmes inbjudan till förhandlingar (se EU & arbetsrätt nr 2/2008 sid 4) överraskade parterna omvärlden i slutet av augusti genom att gemensamt skriva till europeiska kommissionen om vilka ändringar som bör göras i direktivet om europeiska företagsråd (94/45). Det skedde sedan kommissionen lagt fram ett förslag till ändringsdirektiv.

    Arbetsmarknadens parter kritiska till svenska Laval-utredningens förslag2008In: EU & arbetsrätt, ISSN 1402-308, no 4Article in journal (Other (popular science, discussion, etc.))
    Abstract [sv]

    Svenska fackföreningar ska även i fortsättningen kunna vidta stridsåtgärder mot företag från andra EES-stater för att dessa ska ge sina utstationerade arbetstagare villkor enligt svenska kollektivavtal. Det föreslår den svenska utredningen om åtgärder med anledning av Laval-domen som överlämnades den 12 december.

    Uppdraget till utredaren Claes Stråth var att komma med förslag som innebär så små inskränkningar som möjligt i rätten att vidta stridsåtgärder, samtidigt som de respekterar EG-rätten "fullt ut".

    Abstract [sv]

    Hur ska ett utländskt företag få reda på vilken lön det ska betala sina anställda när de utstationeras till Sverige? Ja, knappast genom Arbetsmiljöverket i alla fall, fast det är förbindelsekontor enligt utstationeringslagen. Hittills har bara två fackliga organisationer lämnat in så kallade utstationeringsavtal dit, och fl era förbund har bestämt sig för att inte heller göra det. Men information om vilka kollektivavtalsvillkor ett antal förbund anser vara minimivillkor enligt utstationeringslagen går att hitta på ett annat ställe: på en webbplats som riktar sig till upphandlare i stat och kommun.

    Abstract [sv]

    I vilken utsträckning är det möjligt – det vill säga tillåtet enligt upphandlingslagstiftningen och förenligt med EU-rätten – att kräva att leverantörer tillämpar kollektivavtalsenliga villkor för sina anställda när de utför offentliga kontrakt? Frågan har varit högaktuell i Sverige på sistone och sysselsatt forskare, utredare, myndigheter och juridikstuderande. En ny bit i pusslet med att klargöra rättsläget lades med EU-domstolens dom RegioPost. I den här artikeln redogör jag för rättsläget som det ser ut efter domen RegioPost och avslutar med några personliga reflektioner kring de politiska val som regeringen ställs inför när den nu förbereder sin proposition.

    Abstract [sv]

    Det är inte tillåtet att tvångsomplacera en arbetstagare bara för att han begär att slippa arbeta mer än de 48 timmar i veckan som arbetstidsdirektivet (2003/88) föreskriver. Det konstaterade EU-domstolen i oktober i ett mål som rör brandmannen Günter Fuß. Några veckor senare kom den med ytterligare ett förhandsavgörande som rör samme Günter Fuß. Där slår den fast att denne, i egenskap av offentliganställd, kan åberopa unionsrätten för att kräva skadestånd eller kompensationsledighet av sin arbetsgivare.

    Abstract [sv]

    Vi ber Kommissionen att inte lägga fram ett förslag till direktiv för att göra det europeiska avtalet om hälsa och säkerhet i frisörbranschen bindande i medlemsstaterna. Så skrev företrädare för tio länders regeringar – bland dem den svenska och den finska – i ett brev till Europeiska kommissionen i slutet av förra året. Europafacket kallar initiativet ett exempellöst angrepp och ett farligt prejudikat som kan leda till att hela den så kallade sociala dialogen på EU-nivå kollapsar. Och det är ingen tvekan om att en ny situation har inträffat. Kommissionen, där man lite spydigt talar om ”l’Oréalavtalet”, ser ut att lyssna på brev-skrivarna. Dessutom har även ett avtal om arbetstider inom inlandssjöfarten som slöts vid samma tid fastnat i maskineriet.

    Abstract [sv]

    De nya reglerna om utstationering bör göra klart att medlemsstaterna själva kan bestämma de olika nivåerna för vilka minimilöner som är tilllämpliga. Det skriver den europeiska byggnadsarbetarfederationen EFBWW och dess motsvarighet på arbetsgivarsidan, FIEC, i ettgemensamt förslagtill Europeiska kommissionen. Bakgrunden till förslaget är EU-domstolens dom i måletRüffert (C-346/06), där Niedersachsen ville tillämpa kollektivavtalet för delstaten, men domstolen hänvisade till det kollektivavtal som gällde för hela Tyskland.
