Översyn av förordning om miljökvalitetsnormer för fisk- och musselvatten : Redovisning av regeringsuppdrag med Havs- och vattenmyndighetens analys av normerna och förslag till ändrad lagstiftning
- 2016
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Regeringen gav genom ett beslut den 22 oktober 2015 Havs- och vattenmyndigheten i uppdrag att göra en översyn av förordningen (2001:554) om miljökvalitetsnormer för fisk- och musselvatten (fisk- och musselvattenförordningen). Behovet av att göra denna översyn har framförts av Havs- och vattenmyndigheten, Naturvårdsverket och Länsstyrelsen i Västra Götalands län. I rapporten görs en översyn av miljökvalitetsnormerna i förordningen (2001:554) om miljökvalitetsnormer för fisk- och musselvatten och en bedömning av om det finns normer som bör ändras, tas bort eller om samma skyddsnivå kan uppnås på annat sätt. Havs- och vattenmyndigheten föreslår att fisk- och musselvattenförordningen upphävs. Som en följd av detta behöver ett antal föreskrifter upphävas eller ändras. Därutöver behöver viss vägledning tas fram för att täcka återstående skyddsbehov.Det är svårt att få en överblick av i vilken utsträckning fisk- och musselvattenförordningen har påverkat den övervakning som bedrivs och hur mycket övervakning som bedrivs enbart utifrån förordningens krav. Havs- och vattenmyndighetens bedömning är dock att ett upphävande av förordningen inte kommer att påverka den övervakning som utförs på ett betydande sätt. Konsekvensutredningen visar att fisk- och musselvattenförordningen kan upphävas och att detta medför i huvudsak positiva effekter för såväl miljön som berörda myndigheter och verksamhetsutövare.

Practicing ’intellectus’ in rural entrepreneurship
- 2019
-
Konferensbidrag (refereegranskat)abstract
- In this paper we turn to recent philosophical investigations to analyse stories from entrepreneurial women in rural areas. They describe a variety of social activities they are engaged in to develop their companies, products and services, but also the local community, and society. These engagements are often described in passing, and not directly connected to the company according to conventional goal-oriented logic. Rather, they are seen as taken for granted– they are just done, and someone needs to do them. They concern care for others – for the children in the community, the elderly, the infrastructure, the sustainability of the industry etc. They are neither described as sacrifice, nor as benevolence, as is often emphasized in social entrepreneurship stories. Rather, these engagements signal something else. We argue that they illustrate a reflective practice of entrepreneurship, normally suppressed by an economic logic and described as play, passion and creativity in the sociologically inspired entrepreneurship literature.To better understand the role of reflexive practices in rural entrepreneurship, we turn to philosopher Jonna Bornemark who describes how humans in modern societies have become ‘prisoners’ of the measurable economic rationality (‘ratio’). With inspiration from the pre-renaissance philosopher, Nicholas Cusanus (1401-1464), she describes how the calculating ‘ratio’ has taken precedence over ‘intellectus’. Economic rationality (ratio) describes how we turn to rules of abstractions and generalization. Bornemark’s argument is that too much of ratio makes us loose contact with ourselves, others and the specific situation in a way that disables us to develop judgment. Instead we rely on external parameters to objectively guide our action. Practices built on intellectus, on the contrary, emphasize the subjective, emotional, temporary and our ability to ‘not know’, but to learn to cope with insecurity, instability, anxiety and find ways to act in such terrains. Bornemark’s point is that ratio and intellectus practices are interdependent – both are needed. But, in modern societies intellectus has been suppressed, overlooked and seen as state of lack of better knowledge.But, what if intellectus is a practice that is nurtured in rural contexts? A practice that not only makes it possible for rural areas to survive and thrive, but which we can learn from in the contemporary calls to change global society in a more thoughtful direction. By analyzing stories from 35 women pursuing different businesses and social activities, we set eyes at the question of if, and how, intellectus is practiced by rural entrepreneurial women.

Maternal obesity, duration of labor and the role of leptin
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: The prevalence of obesity substantially increases in pregnant women. Maternal obesity is associated with adverse maternal and neonatal outcomes. The increased risk for cesarean section present in obese women has been related to potential impaired uterine contractility. The mechanism that underlies this theory is not clear. In vitro studies have shown that leptin, produced by adipose tissue and the placenta, exerts an inhibitory effect on myometrial contractility. The aim of this thesis was to evaluate the labor process in relation to maternal body mass index (BMI) and the clinical role of leptin in this process.Material and Methods: Studies I-IV are cohort studies. The first two studies analyze the association between labor duration and maternal BMI based on data from the Perinatal Revision South register and the Swedish Pregnancy Register. Study I included 63,829 nulliparous women with a spontaneous onset of labor between 1995 and 2009. Study II included 15,259 nulliparous women with induced labor between 2014 and 2017. In study III, the maternal leptin levels during and after pregnancy were analyzed in 343 obese women with respect to their obesity class (I-III) and degree of gestational weight gain (GWG). In study IV, the association between the maternal leptin levels measured in active labor and duration of the active phase of labor was analyzed in 914 women.Results: The duration of spontaneous labor significantly increased with an increasing maternal BMI; however, the duration of the pushing phase was inversely related to BMI. Time in induced labor increased with maternal BMI; however, the differences between the BMI categories were more pronounced in the latent phase than the active phase. Leptin levels were higher in women with obesity class III than women with class I during and after pregnancy. The degree of GWG in obese women was not associated with maternal leptin. No significant association between maternal leptin and the duration of the active phase of labor was identified in the adjusted analyses.Conclusions: Nulliparous obese women have a higher risk for a prolonged duration of spontaneous and induced labor. This is important to consider prior to diagnosing labor arrest that results in a cesarean delivery. As maternal leptin levels are increased with the degree of obesity during pregnancy, future research on the association of high maternal leptin levels and the duration of labor is warranted.

Tidskriftsartikel (refereegranskat)abstract
- Simulation results for future measurements of electromagnetic proton form factors at P ¯ ANDA (FAIR) within the PandaRoot software framework are reported. The statistical precision with which the proton form factors can be determined is estimated. The signal channel p¯ p→ e+e- is studied on the basis of two different but consistent procedures. The suppression of the main background channel, i.e.p¯ p→ π+π-, is studied. Furthermore, the background versus signal efficiency, statistical and systematical uncertainties on the extracted proton form factors are evaluated using two different procedures. The results are consistent with those of a previous simulation study using an older, simplified framework. However, a slightly better precision is achieved in the PandaRoot study in a large range of momentum transfer, assuming the nominal beam conditions and detector performance.

- The exclusive charmonium production process in (P) over barp annihilation with an associated pi 0 meson (p) over barp -> J/psi pi(0) is studied in the framework of QCD collinear factorization. The feasibility of measuring this reaction through the J/psi -> e(+) e(-) decay channel with the AntiProton ANnihilation at DArmstadt ((P) over bar ANDA) experiment is investigated. Simulations on signal reconstruction efficiency as well as the background rejection from various sources including the (P) over barp -> pi(+)pi(-)pi(0) and (p) over barp -> J/psi pi(0)pi(0) reactions are performed with PANDAROOT, the simulation and analysis software framework of the (P) over bar ANDA experiment. It is shown that the measurement can be done at (P) over bar ANDA with significant constraining power under the assumption of an integrated luminosity attainable in four to five months of data taking at the maximum design luminosity.

- Bound nuclear systems with two units of strangeness are still poorly known despite their importance for many strong interaction phenomena. Stored antiprotons beams in the GeV range represent an unparalleled factory for various hyperon-antihyperon pairs. Their outstanding large production probability in antiproton collisions will open the floodgates for a series of new studies of systems which contain two or even more units of strangeness at the PANDA experiment at FAIR. For the first time, high resolution gamma-spectroscopy of doubly strange Lambda Lambda-hypernuclei will be performed, thus complementing measurements of ground state decays of Lambda Lambda-hypernuclei at J-PARC or possible decays of particle unstable hypernuclei in heavy ion reactions. High resolution spectroscopy of multistrange Xi(-) -atoms will be feasible and even the production of Omega(-) -atoms will be within reach. The latter might open the door to the vertical bar S vertical bar = 3 world in strangeness nuclear physics, by the study of the hadronic Omega(-) -nucleus interaction. For the first time it will be possible to study the behavior of Xi(+) in nuclear systems under well controlled conditions.

Tidskriftsartikel (refereegranskat)abstract
- Utilizing the dataset corresponding to an integrated luminosity of 2.93 fb(-1) at root s = 3.773 GeV collected by the BESIII detector, we report the first amplitude analysis and branching fraction measurement of the D-0 -> K- pi(+)pi(0)pi(0) decay. We investigate the substructures and determine the relative fractions and the phases among the different intermediate processes. Our results are used to provide an accurate detection efficiency and allow measurement of B(D-0 -> K- pi(+)pi(0)pi(0)) = (8.86 +/- 0.13(stat) +/- 0.19(syst))%.

Amplitude analysis of D+-> K-S(0)pi(+)pi(+)pi(-)
- 2019
-
Ingår i: Physical Review D. - : AMER PHYSICAL SOC. - 2470-0010 .- 2470-0029. ; 100:7

Tidskriftsartikel (refereegranskat)abstract
- The decay D+-> K-S(0)pi(+)pi(+)pi(-) is studied with an amplitude analysis using a data set of 2.93 fb(-1) of e(+)e(-) collisions at the psi(3770) peak accumulated by the BESIII detector. Intermediate states and nonresonant components, and their relative fractions and phases, have been determined. The significant amplitudes, which contribute to the model that best fits the data, are composed of five quasitwo-body decays K(S)(0)a(1)(1260)(+), (K) over bar (1)(1270)(0)pi(+) (K) over bar (1)(1400)(0)pi(+), (K) over bar (1)(1650)(0)pi(+), and (K) over bar (1460)(0)pi(+), a three-body decay K-S(0)pi(+)rho(0), as well as a nonresonant component K-S(0)pi(+)pi(+)pi(-). The dominant amplitude is K(S)(0)a(1)(1260)(+), with a fit fraction of (40.3 +/- 2.1 +/- 2.9)%, where the first and second uncertainties are statistical and systematic, respectively.

Tidskriftsartikel (refereegranskat)abstract
- We present the first amplitude analysis of the decay D-s(+) -> pi(+)pi(0)eta. We use an e(+)e(-) collision data sample corresponding to an integrated luminosity of 3.19 fb(-1) collected with the BESIII detector at a center-of-mass energy of 4.178 GeV. We observe for the first time the W-annihilation dominant decays D-s(+) -> a(0)(980)(+)pi(0) and D-s(+) -> a(0)(980)(0)pi(+). We measure the absolute branching fraction B(D-s(+) -> a(0)(980)(+(0))pi(0(+)), a(0)(980)(+(0)) -> pi(+(0)())eta = (1.46 +/- 0.15(stat )+/- 0.23 sys)%, which is larger than the branching fractions of other measured pure W-annihilation decays by at least one order of magnitude. In addition, we measure the branching fraction of D-s(+) -> pi(+)pi(0)eta with significantly improved precision.
