Harvest Pressure on Coastal Atlantic Cod (Gadus morhua) from Recreational Fishing Relative to Commercial Fishing Assessed from Tag-Recovery Data
2016
- Marine recreational fishing is a popular outdoor activity. However, knowledge about the magnitude of recreational catches relative to commercial catches in coastal fisheries is generally sparse. Coastal Atlantic cod (Gadus morhua) is a target species for recreational fishers in the North Atlantic. In Norway, recreational fishers are allowed to use a variety of traps and nets as well as long-line and rod and line when fishing for cod. From 2005 to 2013, 9729 cod (mean size: 40 cm, range: 15–93 cm) were tagged and released in coastal Skagerrak, southeast Norway. Both high-reward (NOK 500) and low-reward tags (NOK 50) were used in this study. Because some harvested fish (even those posting h…
Toppdommerrollen i fotball : sammenhengen mellom angst og mental tøffhet og toppdommeres subjektive opplevelse av press i norsk fotball
2016
Masteroppgave i idrettsvitenskap - Universitetet i Agder 2016 Mental toughness, anxiety and pressure are well-used terms within sports, even though it can be difficult to understand the meaning of them. The purpose of this study was to examine the relationship between anxiety (cognitive- and somatic anxiety and self-confidence) and mental toughness, and top-class referees’ subjective experience on pressure as a soccer official. 183 top-class referees answered an online questionnaire. Mental toughness was measured by using the SMTQ and anxiety by using the CSAI-2. Of all the referees included in this study, 97.2% had been active footballers themselves, 44.3% had played on a high level. There…
Evaluation of the new ESR network software for the retrieval of direct sun products from CIMEL CE318 and PREDE POM01 sun-sky radiometers
2012
Abstract. The European Skynet Radiometers network (EuroSkyRad or ESR) has been recently established as a research network of European PREDE sun-sky radiometers. Moreover, ESR is federated with SKYNET, an international network of PREDE sun-sky radiometers mostly present in East Asia. In contrast to SKYNET, the European network also integrates users of the CIMEL CE318 sky–sun photometer. Keeping instrumental duality in mind, a set of open source algorithms has been developed consisting of two modules for (1) the retrieval of direct sun products (aerosol optical depth, wavelength exponent and water vapor) from the sun extinction measurements; and (2) the inversion of the sky radiance to derive…
In-situ integrating nephelometer measurements of the scattering properties of atmospheric aerosols at an urban coastal site in western Mediterranean
2012
Abstract Measurements of aerosol scattering properties obtained during the period from March 2006 to December 2010 at Valencia (Spain) have been analyzed. The total aerosol scattering (σsp) and backscattering (σbsp) coefficients were measured using a TSI Model 3563 three-wavelength integrating nephelometer. From the measurements of σsp and σbsp, it was possible to determine also the scattering Angstrom exponent (αs). For the entire measurement period, the mean values (±standard deviation) at 550 nm are: 80 ± 50 Mm−1 for σsp; 8 ± 5 Mm−1 for σbsp; and 1.6 ± 0.3 for αs. These results indicate a moderate polluted atmosphere characterized by fine particles. The daily variation for all seasons sh…
Aerosol influence on radiative cooling
2011
Aerosol particles have a complex index of refraction and therefore contribute to atmospheric emission and radiative cooling rates. In this paper calculations of the longwave flux divergence within the atmosphere at different heights are presented including water vapour and aerosol particles as emitters and absorbers. The spectral region covered is 5 to 100 microns divided into 23 spectral intervals. The relevant properties of the aerosol particles, the single scattering albedo and the extinction coefficient, were first calculated by Mie-theory and later by an approximation formula with a complex index of refraction given by Volz. The particle growth with relative humidity is also incorporat…
Sources of discrepancy between aerosol optical depth obtained from AERONET and in-situ aircraft profiles
2012
Abstract. Aerosol optical properties were measured by NOAA's Airborne Aerosol Observatory over Bondville, Illinois, during more than two years using a light aircraft. Measured properties included total light scattering, backscattering, and absorption, while calculated parameters included aerosol optical depth (AOD), Ångström exponent, single-scattering albedo, hemispheric backscatter fraction, asymmetry parameter, and submicrometer mode fraction of scattering. The in-situ aircraft measurements are compared here with AERONET measurements and retrievals of the aerosol optical properties at the same location, although it is difficult to verify the AERONET retrieval algorithm at a site that is …
The causal representation of outpatients with Crohn's disease: is there a link between psychological distress and clinical disease activity?
2013
Objectives: Because of the fluctuating and occasional character of Crohn’s disease (CD), patients have to cope with a changeable condition of health. Personal perceived control is known to be an important element of adaptation to their medical condition. The objectives of this work are to determine if perceived personal control is predictive of the clinical activity of the disease and of psychological distress (depression, anxiety). Methods: The Hospital Anxiety Depression Scale (HADS), the causal dimension scale and the Clinical Global Impression (CGI; assessing perceived severity) were administered to 160 patients affected by Crohn’s disease. Indicators of inflammation (CRP), disease dura…
A comparative study of SPCTRAL2 and SMARTS2 parameterised models based on spectral irradiance measurements at Valencia, Spain
1998
Abstract Results obtained using the parametric models SPCTRAL2 and SMARTS2 for the urban area of Valencia, Spain, have been analysed and compared with experimental measurements at ground level obtained with two Li-cor 1800 spectroradiometers with a 6 nm resolution. The study used two different input parameters in both models for the aerosol characterisation: the aerosol optical thickness at 0.5 μ m, τ a λ (0.5) , and the Angstrom turbidity coefficient β . The results obtained show that both algorithms reproduce quite correctly the spectral irradiance experimental values when an urban aerosol model parameterised by the τ a λ (0.5) value is considered. In all the cases the deviations are low…
Angstens filosofi
2003
Angst har vært et viktig tema i nyere filosofi. Etter en kort introduksjon til fenomenologisk metode, gis det i denne artikkelen en presentasjon av Søren Kierkegaards, Martin Heideggers og Jean-Paul Sartres bidrag til angstens filosofi. Her relateres angstfølelsen til erfaring av intethet og til den grunnleggende eksistensielle friheten. Med utgangspunkt i denne filosofiske teorien gis en drøfting av hvordan angsten kan oppfattes som et uttrykk for en indre spenning. Til slutt vises det hvordan den filosofiske angstteorien kan relateres til konkrete angstformer og angstlidelser.
Estimation of daily average values of the Ångström turbidity coefficient β using a Corrected Yang Hybrid Model
2013
This paper aims to test a method for estimating daily values of atmospheric turbidity from non-specialized data, such as those obtained from agro-meteorological stations. This method allows estimating the spatial and temporal evolution of aerosols concentration in more places than just those in which direct measurements are available. The method is based on the Corrected Yang Hybrid Model (CYHM). The data used in the determination of errors between measured and estimated values of the daily Angstrom turbidity coefficient β were recorded in Valencia, Spain, during 2009 and 2011. These data were global solar irradiance, direct solar irradiance, temperature, relative humidity and Aerosol Optic…
