Realfag og teknologi for marineoffiseren
Get PDFDen Kongelige Norske Marine hadde sitt 200 års-jubileum
i 2014. I 2017 er det Sjøkrigsskolens tur. Siden
utdanning av marineoffiserer ble den norske stats ansvar,
har Sjøkrigsskolen hatt et innhold bestående av
teoretiske og praktiske emner tilpasset de sjømilitære
forhold. De matematiske, naturvitenskapelige og tekniske
fag har hele tiden hatt stor plass og betydning. De
danner grunnlaget for tenkning og metodisk tilnærming.
I disse snart 200 år har marineoffiserene opplevd
en enorm teknologisk utvikling. Skrogtyper, materialer,
maskineri, elektrisitet, radio, artilleri, torpedoer, miner,
sjøfly, radar, sonar, missiler, programmerbare analoge og
digitale datamaskiner, for å nevne noe. Sjøkrigens natur
er utfordrende – et krigsfartøy må kunne operere på
egenhånd, i all slags vær, langt fra hjelp og assistanse og
over lang tid. Disse forhold har preget Sjøkrigsskolen og
utdanningen av de kommende offiserer. Historisk har
marineoffiseren ofte tatt initiativ for å prøve ut og lære
seg nyvinninger slik at en ikke blir akterutseilt. Historier
som marineoffiseren Kaptein Carsten Tank-Nielsen
som tok initiativ, ble valgt ut, fikk stipend, studerte elektroteknikk
og motorlære ved den tekniske høyskolen i
Hannover for å kunne lære seg det nye ubåtvåpenet. Han
beordret videre Premierløytnant Hans Fleischer Dons,
som også hadde blitt sendt av den norske stat til Tyskland
for å studere elektronikk ved høyskolen i Charlottenburg,
til på ny å reise tilbake for å lære seg å fly. I mellomtiden
var undervannsbåten Kobbens flykomité i gang med å
samle inn penger til flykurs og flykjøp. Den 1.juni 1912
lettet Marinens første fly med Dons bak spakene og
Carsten Tank-Nielsen som første passasjer.
Sjøkrigsskolens oppgave er å sørge for at de nyutdannede
offiserene er godt skolert slik at de gjennom videre
oppøving og trening er i stand til å utnytte de tekniske
innretninger og ikke minst ha holdninger og kunnskap
som bidrar til å drifte det hele til så lav kostnad som
mulig. Lærerkreftene ved Sjøkrigsskolen har alltid bestått
av sivile og militære slik at de teoretiske og praktiske
sammenhenger ivaretas. De sivile dosentene ble i
sin tid ansatt som embetsmenn og har vært med å prege
Sjøkrigsskolens utvikling med sin stabilitet. Den siste
av embetsmennene ved Sjøkrigsskolen, dosent Dagfinn
Andreassen, har i dette nummeret nyttet anledningen til
å se litt tilbake innen matematikkundervisningen og tar
også frem forhold rundt dagens situasjon.
Alt endrer seg og innen utdanning er det spesielt vanskelig
å se konsekvenser av disse da det alltid vil gå
mange år før det er mulig å se hvordan handlinger og
beslutninger er blitt påvirket.
Dette nummeret av Necesse speiler litt av aktiviteten
ved Sjøkrigsskolen. Nye hjelpemidler innen undervisning
åpner for nye måter å gjennomføre utdanningen.
Den digitale verden betyr mange nye muligheter, både
innenfor det pedagogiske, men også innen det tekniske.
For marineoffiseren har det vært, og er, viktig å følge
med, teste og eksperimentere for å få mest mulig innsikt
i teknologiens styrker og svakheter.
Matematikk, statistikk og sannsynlighetsteori er kunnskap
som er viktige innen flere marine relaterte områder.
Vanskelig for noen, lettere for andre, men viktig for
en organisasjon som skal bruke og forvalte en Marine
bestående av stadig færre, men mer kapable enheter.
Utviklingen er at det blir færre mennesker ombord, alle
må kunne mer og bidra til å holde teknologien i gang.
I dette nummeret er det flere eksempler på matematisk
anvendelse og ett eksempel, spesielt, på anvendelse av
kunnskap tilegnet, basert på studiene ved skolen, et
kadettarbeid - en bachelor oppgave - gjennomført til
høyeste karakter. Den viser meget godt hvordan god
matematikk kan løse og håndtere et praktisk problem.
Vi håper du finner innholdet i denne utgaven av Necesse
engasjerende, og vi oppfordrer deg mer enn gjerne til å

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
