    Description: "The purpose of this study was to examine factorial, convergent, discriminant, and criteria validity of a multi-dimensional scale measuring coaching efficacy (Feltz, Chase, Moritz, & Sullivan, 1999). The sample consisted of 281 Norwegian grassroot football coaches taking part in two data collections (across the football season) within the Norwegian arm of the international PAPA project (intervention group, n = 193) and control group, n = 88). Latent variable modeling supported a 4-factor model reflecting Motivation efficacy, Strategy efficacy, Technique efficacy and Character efficacy. An introductory ESEM analysis of the 24-item coaching efficacy scale yielded an acceptable solution after omitting two items. A parceling approach of the twenty-two items were then converted into eleven parcels to examine factorial validity and time and group invariance. The four-factor model based on parcels obtained good fit indices: (S-B χ2 = [df = 29, n = 222] = 38.622, p 〈 .011 (ns.); RMSEA = .039; 90% (CI = .000–.068); CFI = .99; SRMR = .023). Moreover, we obtained strong support for time invariance for a merged solution of the two groups of coaches. Invariance across time for the intervention and control group separately was supported at time 1, but not at time 2. Satisfactorily convergent, discriminant, and criteria validity were also supported. The scale needs further validation before use in intervention studies."
    Description: "Formålet med denne studien var å teste dimensjons-, konvergens -, diskriminant- og kriterievaliditet for en norsk versjon av Feltz, Chase, Moritz og Sullivan (1999) – Coaching Efficacy Scale. Invarians over tid og mellom grupper ble også inkludert med tanke på prospektiv bruk av skalaen i form av lengdesnittstudier og effektstudier. Utvalget omfattet 281 norske breddefotballtrenere i tre norske fotballkretser. Disse deltok i datainnsamlinger før (T1) og etter sesong (T2) i den norske delen (Solstad, 2017) av det internasjonale PAPA-prosjektet (Quested et al., 2013). Innledende eksplorativ faktoranalyse i Mplus støttet en forventet 4-faktors mestringstromodell som reflekterte henholdsvis: Motivasjon, Kampstrategi, Teknikk og Karakterbygging. To utsagn viste høy residualvarians og ble eliminert. En oppfølgende analyse basert på 22 utsagn gav tilfredsstillende tilpasningsindekser (S-B χ2 = [df = 149, n = 222] = 312.901, p 〈 .001; RMSEA = .070; 90% konfidensintervall (CI = .059–.081); CFI = .94; SRMR = .025). Ved parselleringsteknikk (Kline, 2011; Little, Rhemtulla, Gibson, & Schoemann, 2013) ble 22 utsagn konvertert til elleve parseller som basis for sjekk av faktorvaliditet og invarians over tid og mellom grupper ved hjelp av latent variabelanalyse. De elleve parsellene gav svært gode tilpasningsindekser; (S-B χ2 = [df = 29, n = 222] = 38.622, p 〈 .011 (ns.); RMSEA = .039; 90% (CI = .000–.068); CFI = .99; SRMR = .023). I tillegg fant vi entydig støtte for sterk skaleringsinvarians over tid (fotballsesongen; T1–T2) for intervensjons- og kontrollgruppe samlet. Invarians splittet på intervensjons-/kontrollgruppe kunne derimot ikke påvises. Vi observerte også god konvergent og diskriminerende validitet. Kriterievaliditet ble også bekreftet. I sum synes skalaen å være velegnet til undersøkelse av tverrsnitt- og lengdesnittstudier av treneres mestringstro i barne- og ungdomsidrett. Skalaen trenger ytterligere validering før bruk i intervensjonsstudier."

    Description: Originally developed by the Canadian sociologist Dorothy E. Smith, institutional ethnography is an approach to research that aims to explore and challenge power relations in society. In Norway and the other Nordic countries, the approach is used by researchers in a variety disciplines and professional fields. In Experiences with Institutional Ethnography, we gain insight into several different researchers’ motivation for, experiences with and reflections on delving into and using institutional ethnography in their own research. We gain insight into specific research processes and their attendant methodological approaches, into experiences of using key concepts from institutional ethnography, and into reflections on the researcher's role. This book will be a useful tool for researchers, master’s students and research fellows who utilize – or are considering utilizing – institutional ethnography in their work.
    Description: Institusjonell etnografi er en forskningstilnærming som opprinnelig ble utviklet av den kanadiske sosiologen Dorothy E. Smith, og som har som formål å utforske og utfordre maktforhold i samfunnet. I Norge og Norden for øvrig brukes tilnærmingen av forskere fra ulike disipliner og fagfelt. I Erfaringer med institusjonell etnografi får vi innblikk i ulike forskeres motivasjon for, erfaringer med og refleksjoner rundt å sette seg inn i og bruke institusjonell etnografi i sin egen forskning. Vi får innblikk i bestemte forskningsprosesser og metodiske grep i slike prosesser, i erfaringer med å bruke sentrale begreper fra institusjonell etnografi og i refleksjoner over forskerrollen. Boken er et nyttig redskap for forskere, masterstudenter og stipendiater som benytter – eller vurderer å benytte – institusjonell etnografi i sin forskning.

    Description: Ensemble articulé d'une trentaine d'études sur les femmes et la justice, cet ouvrage constitue la première synthèse sur ce sujet peu connu qui s'intercale entre le domaine du droit en amont, et celui de la peine – et notamment de la prison – en aval. Il se concentre sur l'histoire contemporaine de quelques pays occidentaux, particulièrement la France et le Canada. Femmes et justice : ce thème dessine d'abord les contours d'une histoire spécifique, celle des illégalismes féminins (vol domestiq...

    Description: Prononcée en 2002 à l’occasion de l’ouverture de la chaire Évolution du climat et des océans, la leçon inaugurale d’Edouard Bard n’a rien perdu de son actualité. Elle nous rappelle que le réchauffement climatique est une préoccupation de longue date d’une partie de la communauté scientifique, qui disposait déjà depuis des décennies de données nombreuses et étayées. À travers une description de l’histoire du climat, l’auteur croise les approches complémentaires de la paléoclimatologie, de l’océanographie et de la géologie pour mieux analyser et contextualiser le réchauffement global que subissent aujourd’hui le climat et les océans. Ce texte précurseur résonne comme un avertissement qui vient faire écho aux préoccupations contemporaines face aux grands enjeux climatiques de notre époque.

    Description: Radiocarbon (14C) concentrations in the oceans are different from those in the atmosphere. Understanding these ocean-atmospheric 14C differences is important both to estimate the calendar ages of samples which obtained their 14C in the marine environment, and to investigate the carbon cycle. The Marine20 radiocarbon age calibration curve is created to address these dual aims by providing a global-scale surface ocean record of radiocarbon from 55,000–0 cal yr BP that accounts for the smoothed response of the ocean to variations in atmospheric 14C production rates and factors out the effect of known changes in global-scale palaeoclimatic variables. The curve also serves as a baseline to study regional oceanic 14C variation. Marine20 offers substantial improvements over the previous Marine13 curve. In response to community questions, we provide a short intuitive guide, intended for the lay-reader, on the construction and use of the Marine20 calibration curve. We describe the choices behind the making of Marine20, as well as the similarities and differences compared with the earlier Marine calibration curves. We also describe how to use the Marine20 curve for calibration and how to estimate ΔR—the localized variation in the oceanic 14C levels due to regional factors which are not incorporated in the global-scale Marine20 curve. To aid understanding, illustrative worked examples are provided.

    Description: The Marine20 radiocarbon (14C) age calibration curve, and all earlier marine 14C calibration curves from the IntCal group, must be used extremely cautiously for the calibration of marine 14C samples from polar regions (outside ∼ 40ºS–40ºN) during glacial periods. Calibrating polar 14C marine samples from glacial periods against any Marine calibration curve (Marine20 or any earlier product) using an estimate of , the regional 14C depletion adjustment, that has been obtained from samples in the recent (non-glacial) past is likely to lead to bias and overconfidence in the calibrated age. We propose an approach to calibration that aims to address this by accounting for the possibility of additional, localized, glacial 14C depletion in polar oceans. We suggest, for a specific polar location, bounds on the value of during a glacial period. The lower bound may be based on 14C samples from the recent non-glacial (Holocene) past and corresponds to a low-depletion glacial scenario. The upper bound, , representing a high-depletion scenario is found by increasing according to the latitude of the 14C sample to be calibrated. The suggested increases to obtain are based upon simulations of the Hamburg Large Scale Geostrophic Ocean General Circulation Model (LSG OGCM). Calibrating against the Marine20 curve using the upper and lower bounds provide estimates of calibrated ages for glacial 14C samples in high- and low-depletion scenarios which should bracket the true calendar age of the sample. In some circumstances, users may be able to determine which depletion scenario is more appropriate using independent paleoclimatic or proxy evidence.

    Description: Radiocarbon (14C), as a consequence of its production in the atmosphere and subsequent dispersal through the carbon cycle, is a key tracer for studying the Earth system. Knowledge of past 14C levels improves our understanding of climate processes, the Sun, the geodynamo, and the carbon cycle. Recently updated radiocarbon calibration curves (IntCal20, SHCal20, and Marine20) provide unprecedented accuracy in our estimates of 14C levels back to the limit of the 14C technique (~55,000 years ago). Such improved detail creates new opportunities to probe the Earth and climate system more reliably and at finer scale. We summarize the advances that have underpinned this revised set of radiocarbon calibration curves, survey the broad scientific landscape where additional detail on past 14C provides insight, and identify open challenges for the future.
