Plastic Rain in Protected Areas of the United States
Eleven billion metric tons of plastic are projected to accumulate in the environment by 2025. Because plastics are persistent, they fragment into pieces that are susceptible to wind entrainment. Using high-resolution spatial and temporal data, we tested whether plastics deposited in wet versus dry conditions have distinct atmospheric life histories. Further, we report on the rates and sources of deposition to remote U.S. conservation areas. We show that urban centers and resuspension from soils or water are principal sources for wet-deposited plastics. By contrast, plastics deposited under dry conditions were smaller in size, and the rates of deposition were related to indices that suggest longer-range or global transport. Deposition rates averaged 132 plastics per square meter per day, which amounts to \u3e1000 metric tons of plastic deposition to western U.S. protected lands annually
Ledarskapsutbildning â till vilken nytta? - En studie om chefers försök att tillĂ€mpa det som förmedlats under en ledarskapsutbildning
Ă
rligen investeras Ätskilliga summor pÄ ledarskapsutbildning. Studier visar dock att den kunskap
som utvecklas under utbildningen i begrÀnsad utstrÀckning tillÀmpas i arbetskontex- ten. För att
kunna dra nytta av de satsningar som görs pÄ ledarskapsutbildningar, mÄste det inom organisationer
bli högsta prioritet att skapa goda förutsÀttningar för medarbetare att anvÀnda sig av de kunskaper
som utbildningen syftat till att lÀra ut. Kontextuella faktorer har visat sig vara av avgörande
betydelse för individens möjligheter att anvÀnda sig av det som förmedlats under en utbildning.
Syftet med denna studie har varit att undersöka hur en organisation kan skapa förutsÀttningar för
chefer att anvÀnda det som förmedlats under en ledarskapsutbildning i sitt dagliga arbete, samt ge
fördjupad kunskap om vilka hinder och möjligheter chefer upplever i sina försök att tillÀmpa det
som lÀrts in under en genomgÄngen ledarskapsutbildning. Forskningsproblemati- ken har studerats med
utgÄngspunkt i en organisation som vid tidpunkten för genomförandet av studien stod inför
utmaningen att lyckas implementera de operativa chefernas nyförvÀr- vade kunskaper frÄn en
genomförd ledarskapsutbildning, i verksamheten. För att besvara studiens forskningsfrÄgor har tio
kvalitativa intervjuer med operativa chefer inom organisat- ionen genomförts. Insamlad data har
bearbetats genom en innehÄllsanalys och sedan analyserats, tolkats och diskuterats i relation till
studiens teoretiska utgÄngspunkter och ett urval av tidigare forskning inom omrÄdet
kunskapsöverföring.
Resultatet visar att samtliga chefer i efterhand har mÄlat upp en positiv bild av den
genomförda utbildningen och att de upplever utbildningsinnehÄllet som relevant för rollen som chef
inom organisationen, vilket indikerar att cheferna varit benÀgna att anvÀnda det som förmedlats
under utbildningen. Det framstÄr ocksÄ som att benÀgenheten att anvÀnda utbildningsinnehÄllet i
sitt dagliga arbete pÄverkas av tidigare erfarenheter och förhÄllnings- sÀtt. VÄrt resultat
indikerar Àven att det finns ett flertal faktorer som kan utgöra hinder eller möjligheter i
chefernas försök att tillÀmpa de kunskaper som förmedlats under ledarskapsut- bildningen och att
det finns bÄde positiva och negativa aspekter av de flesta av dessa faktorer. NÄgra av de faktorer
som Àr av betydelse Àr autonomin och handlingsfriheten i arbetet, de normer som rÄder inom
organisationen, samt det sociala stödet frÄn överordnad och kollegor
Spore production and beetle visitation on the polypore Fomitopsis pinnicola
Insects and fungi are important parts of dead wood systems. Polypores, the main structural decomposers of dead wood, have fruiting bodies frequently visited by insects. This could potentially be important for spore dispersal, but few studies have investigated whether insect visitation correlates with spore production.
In this study nine time-lapse cameras were used to register beetle visits on Fomitopsis pinicola in Nordre Pollen and Ăstmarka nature reserve. In addition passive spore traps were used to monitor spore production for five polypores in Nordre Pollen once a month, from May to August to see how visiting rates of beetles related to spore production, time of day, air humidity and temperature.
Spore production was at its peak in May, followed by June. No spores were found in August and only two polypores released spores during July. Activity of 4 beetle species was estimated from 51 852 high quality images and spore production was a good predictor for occurrence of beetles in May.M-ECO
The financial impact of informal economic sanctions : an empirical study of the impact of Chinaâs informal economic sanctions on Norwegian salmon exports following the 2010 Nobel Peace Prize
In this study, we have investigated whether the Chinese informal economic sanctions against Norwegian salmon had a negative effect on Norwegian salmon exporting firmsâ financial performance. According to theory on international trade, economic sanctions distorts trade flows between countries and reduce the potential benefits and welfare gains from trade. Since trade takes place through firms, it is expected that firms will be negatively affected by economic sanctions. However, a firmâs opportunity to circumvent such market distortions could lead to a different conclusion.
We performed a fixed effects estimation to examine whether Norwegian salmon exporters were financially affected by the Chinese sanctions. Our results indicate that the Chinese sanctions had a negative financial impact on Norwegian salmon exporting firms, and that this negative effect was larger in the first three years of the sanction period. This can be explained by the different costs an exporting firm may face when economic sanctions are imposed. However, the observed long-run effect is close to zero, supporting the empirical literature stating that sanctions-busting activities are always likely.
The normative implications of our study stress the importance of countries developing and evaluating their exporting industriesâ normative standards to prevent the potential criminalizing side effects of economic sanctions. However, firms are also responsible in these manners. Bribery and smuggling are criminalized because of their harmful consequences and informal economic sanctions are no legitimate excuse for criminal practices.nhhma
Cougars in Cache: Approaching the beast from multiple perspectives
The cougar (Puma concolor) is a notoriously difficult study animal due to its elusive behavior, wide-ranging movements, and low density on the landscape. As a result, the majority of information about cougars comes solely from human-caused mortality records, which are both a biased and imprecise measure of the population as a whole. Additionally, harvest rates of cougars have been increased over the past few years despite a lack of concrete information on Utah cougar populations. Therefore, more accurate means of monitoring are necessary to guide state management of the species. By using and comparing multiple methods for cougar monitoring, including trail cameras, tracking, hunting records, extensive literature review, and public sightings, our research group has been able to gather information about cougar activity in the Cache area. Success of such a complex project has hinged on recruiting research partners and volunteers to participate. Our research contributes to the knowledge of the local wildlife populations and highlights the benefits and risks of implementing large-scale research via citizen scientists
Pigment Composition of Macroalgae from a Norwegian Kelp Forest
Variation in pigment composition between seasons in 10 different species of macroalgae was examined using high precision liquid chromatography (HPLC). In addition, a study on the variation of pigment quantity and quality with tissue age was performed on the kelp Saccharina latissima. All species contained Chlorophyll a (Chl a), and all Phaeophytes contained the accessory chlorophylls, Chl c1+2 in addition to the carotenoids fucoxanthin, violaxanthin, antheraxanthin and zeaxanthin. In the two Rhodophytes examined, the major pigments in addition to Chl a was &#946;,&#946;-carotene and zeaxanthin. Within each species, the light harvesting pigments follows the same tissue concentration trend as Chl a. No similar trend of seasonal variation in pigment composition was seen between species. In the Phaeophytes, the three Fucus species tended to have high pigment content, while Ascophyllum nodosum was recurring as the species with the lowest concentration of all pigments. There was no influence of tissue age in pigment content in the February samples of S. latissima, whereas age influence was seen both in May and September. The light harvesting pigments (LHPs) Chl a, fucoxanthin, Chl c and violaxanthin was detected in all seasons in S. latissima, while Zea was only detected in the May samples and antheraxanthin only in the September samples. In general for S. latissima, February showed the highest concentration of all LHP, while there was a decrease towards May and September. Shading and position in relation to light of macroalgae in the water column determines the pigment content in the wrack and kelp species studied. The limits for high (>1000 &#956;g)/intermediate (500-1000 &#956;g)/low content (<500 &#956;g) of Chl a per gram wet weight, reveals that Phaeophytes and Rhodophytes have a highly variable Chl a content (101-1997 &#956;g for Phaeophytes, 219-1303 &#956;g for Rhodophytes) within PG, while the Chlorophytes generally showed less variation in [Chl a] with seasons (828-1656&#956;g)

MÄl- og resultatstyring i universitets- og hÞgskolesektoren. Institusjonell autonomi eller departemental kontroll? Eller bÄde og? 1990-2015.
Masteroppgaven studerer mÄl- og resultatstyring i hÞyere utdanning fra ca. 1990-2015. Et utvalg fra tre hovedtyper statlig hÞyere utdanningsinstitusjoner er valgt for nÊrmere dybdestudier: Et universitet, Norges teknisk-naturvitenskapelige universitet (NTNU); en hÞgskole, HÞgskolen i Oslo og Akershus (HiOA); og en vitenskapelig hÞgskole, Norges HandelshÞyskole (NHH). MÄl- og resultatstyring beskrives i oppgaven slik det kom til syne blant annet gjennom Kvalitetsreformen, og i universitets- og hÞgskoleloven av 2005. Spesiell oppmerksomhet rettes mot hÞgskolestyrene og andre administrative deler av de hÞyere utdanningsinstitusjonene, i tillegg til Kunnskapsdepartementet styringssignaler via bl.a. tildelingsbrev. Hovedproblemstillingen det jobbes ut i fra er hvilke utfall prinsippet fikk i de hÞyere utdanningsinstitusjonene med hensyn til institusjonenes autonomi: Hvilke konsekvenser fikk mÄl- og resultatstyringsprinsippet for universitetenes og hÞgskolenes virksomhet og autonomi slik prinsippet forekom/manifesterte seg i Kvalitetsreformen, nytt finansieringssystem og den nye universitets- og hÞgskoleloven av 2005
