Valg av ny vegtrasé fra Kårstø til Våg, E39
For prosjektet ”Ferjefri E39”, opprettet i regi av Statens vegvesen, skal det i løpet av en tjueårsperiode bygges en
ferjefri E39 fra Kristiansand til Trondheim. Prosjektet er med i Nasjonal transportplan for 2014-2023. Et av målene
med Ferjefri E39 er å forbedre den generelle vegstandarden langs E39. En eksisterende vegstrekning, Kårstø til Våg
i Rogaland fylke, er en delstrekning i prosjektet. Denne strekningen ligger i nærheten av Haugesund i Tysvær
kommune. Det er denne vegstrekningen som gjennomgås i masteroppgaven for å finne det beste alternativet til en ny
vegtrasé som skal erstatte den eksisterende.
Den nye vegtraséen skal bygges etter H11-standard. Det betyr at vegen bygges med fire felt og midtdeler med en
dimensjonerende fartsgrense på 110 km/t. Dagens veg består av to felt uten midtdeler med en fartsgrense varierende
fra 60-80 km/t. Strekningen fra Kårstø til Våg har en rekke sårbare landskapsformer, variert terreng, flere tettsteder,
vann, nærhet til fjord og utfordringer i forhold til miljø. Målet med oppgaven er å finne det beste alternativet for en
vegtrasé der det er tatt hensyn til tekniske utfordringer og klimagassutslipp, i tillegg til faktorene ovenfor.
For å komme frem til anbefalt vegtrasé ble det sett på tolv forslag til vegtraséer i en innledende fase av
masteroppgaven. Disse alternativene ble så redusert til tre alternativer ut fra vurderinger i forhold til ulendt terreng,
myrer, innsjøer, fjordkryssinger, kommuneplan for Tysvær kommune, miljødata og horisontal- og vertikalgeometri.
Konstruksjonsverktøyet Novapoint ble brukt som hjelpemiddel for å lage veglinjene for alternativene.
For de tre gjenstående alternativene ble det gjennomført en konsekvensanalyse. Her ble prissatte og ikke-prissatte
konsekvenser med håndbok V712 som hjelpemiddel gjennomgått. De utvalgte konsekvensene i en tilpasset analyse
var for de prissatte konsekvensene; anleggskostnader, trasélengde, masseberegning og stigningsgrad, sett i
sammenheng med klimagassutslipp. For de ikke-prissatte konsekvensene ble alle konsekvensene fra håndbok V712
brukt; landskapsbilde, nærmiljø og friluftsliv, naturmangfold, kulturminner og naturressurser, i tillegg til kommuneplanen
for Tysvær kommune. Konsekvensanalysen ga grunnlag til å rangere alternativene opp mot hverandre.
Klimagassutslipp sett i forhold vegutforming har vært et fokusområde i oppgaven gjennom et litteraturstudium. Det
er sannsynlig at bygging av en ny vegtrasé etter H11-standard vil gi reduserte utslipp fordi vegkvaliteten,
kurvaturen, flyt i trafikken og stigningsgraden forbedrer seg. På den annen side vil økt kvalitet på vegen og økt
fartsgrense føre til generert og ny trafikk, og derfor økt klimagassutslipp. Ved at den dimensjonerende fartsgrensen
økes til 110 km/t blir fartsgrensen økt i forhold til optimalhastigheten, 80 km/t, for reduksjon av klimagassutslipp
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Square Dancing with the Stars to Enhance Dynamic Hirschman Linkages?
In this Presidential Address, the author takes the reader on a reconnaissance of his life and time as a regional scientist. He points out scenery he found scintillating along the way, hoping that some may pick up the banner and chew on a few of the ideas for a while. He suggests a revisit to Albert O. Hirschman’s notion of key sectors and more empirical analysis related to Marcus Berliant’s and Masahisa Fujita’s notion of knowledge creation and transfer.Presidential Address, San Antonio, Texas, March 29, 2014 (53rd Meetings of the Southern Regional Science Association
Appropriate Similarity Measures for Author Cocitation Analysis
We 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
We 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
Mannan Enhances IL-12 Production by Increasing Bacterial Uptake and Endosomal Degradation in L. acidophilus and S. aureus Stimulated Dendritic Cells
The mannose receptor (MR) is a C-type lectin involved in endocytosis and with a poorly defined ability to modulate cellular activation. We investigated the effect of mannan treatment prior to stimulation of murine bone marrow-derived dendritic cells with the Gram-positive bacteria Lactobacillus acidophilus NCFM (L. acidophilus) on the induction of Interleukin (IL)-12. Mannan enhanced the IL-12 production induced by L. acidophilus in a dose dependent manner (up to 230% enhancement). Additionally, mannan-enhanced IL-12 induction was also demonstrated with another Gram-positive bacteria, Staphylococcus aureus (S. aureus), while an IL-12 reducing effect was seen on Escherichia coli stimulated cells. Furthermore, the expression of Interferon β (Ifnb) was increased in cells treated with mannan prior to stimulation with L. acidophilus. The addition of mannan but not of bacteria led to endocytosis of MR, while addition of mannan prior to L. acidophilus or S. aureus resulted in increased endocytosis of bacteria, a faster killing of endocytosed bacteria, and increased reactive oxygen species production. Expression of signaling lymphocytic activation molecule (SLAMF)1 shown previously to be involved in the facilitation of endosomal degradation was upregulated by mannan but not by L. acidophilus and S. aureus. The IL-12 enhancement by mannan but not the IL-12 induced by the bacteria was abrogated by addition of inhibitors of clathrin coated pits (chlorpromazine and monodansylcadaverine). Furthermore, the addition of acid sphingomyelinase, a facilitator of ceramide raft formation, prior to addition of L. acidophilus enhanced the IL-12 production and the endocytosis of bacteria. In summary, our results show that mannan increases the IL-12 production induced by some Gram-positive bacteria through MR-endocytosis, which increases bacterial endocytosis and endosomal killing. The differential effect of MR activation on the IL-12 production induced by Gram-positive and Gram-negative bacteria may influence the immune response toward allergens and other glycoproteins
