Nudging - a new planning tool for sustainable travel?
No full textHållbarhet har under de senaste decennierna blivit ett kraftfullt nyckelbegrepp som präglar trafikplaneringens riktlinjer. I kombination med de åtgärder som under många år använts för att öka andelen hållbara resor inom transportsektorn, såsom forskning om elbilar och alternativa bränslen, har på senare år även beteendepåverkande åtgärder implementerats under konceptet mobility management. En aktuell teori i sammanhanget är nudge-teorin, vilken innefattar hur beslutsfattare kan hjälpa människor att fatta bra beslut genom mindre åtgärder: genom att ge dem en knuff i rätt riktning, utan att kräva ekonomiska incitament eller begränsa människors valmöjligheter (Thaler och Sunstein 2008). Nudging som koncept är fortfarande relativt outforskat inom trafikplanering, även det finns vissa likheter med mobility management. Syftet med denna studie är att öka förståelsen om konceptet nudging samt undersöka dess kvaliteter som planeringsverktyg för att påverka resebeteenden. Genom att studera fem kommuner som alla deltagit i det EU-finansierade projektet Knuffa resan rätt, undersöker uppsatsen hur nudge-åtgärder har använts samt hur användarna uppfattat att arbeta med verktyget. Uppsatsen ämnar också belysa hur de deltagande kommunerna tidigare arbetat med beteendepåverkande åtgärder och vilka skillnader de upplever med användandet av nudging som verktyg. Denna studie är en flerfallstudie, där intervjuer har använts som huvudmetod för att samla in empiriska data om de fem olika fallen som studien består av. I kombination med denna metod utfördes även en litteraturstudie, där relevant litteratur om hållbarhet och trafikplanering samlats in, samt ett teoretiskt ramverk om beteendevetenskap, där teorin om nudging lyfts fram. Resultatet från fallstudierna visar att nudging ses som ett nytt spännande verktyg bland kommunerna, även om somliga påpekar att verktyget omedvetet tidigare använts. Skillnaden avser etableringen av nudging som begrepp, samt att kommunerna nu fått en förståelse för teorierna bakom nudging, hämtade från beteendeekonomin. Dessa kunskaper har bidragit till en medvetenhet som kommer effektivisera, men också rättfärdiga, framtida beteendepåverkande projekt inom kommunerna. Däremot finns en problematik vad gäller arbetsprocessen vid nudge-åtgärder. I synnerhet krävs en mer omfattande utvärdering vilket resulterar i än mer resurskrävande projekt. Sannolikt kommer det krävas viss modifikation och flera omgångar av testprojekt innan ett bättre koncept eller modell har utvecklats som effektiviserar nudging som exklusivt planeringsverktyg. Tills dess bör insikterna om nudging användas främst som ett komplement till redan befintliga planeringsverktyg, med syftet att i stället effektivisera dessa
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
