No full textTitel: Fastighetsmäklares beslutsprocess - Beslut vid värdering av bostadsfastigheter och fastställande av utgångspris. Problembakgrund: En bostadsaffär är för många privatpersoner den största affären i livet. Att köpa och sälja en bostadsfastighet är en komplicerad process och fastighetsmäklare finns därför för att hjälpa parterna i processen. Vid bostadsaffärer rör det sig om stora transaktioner och misstag kan ge stora ekonomiska konsekvenser för kunden. Fastighetsmäklare befinner sig i en unik situation där mäklaren måste värna om både säljarens och köparens intresse. Värdering av en bostadsfastighet är därför en central del av fastighetsmäklares arbete, då priset påverkar både köparen och säljaren. Vid värderingen tar fastighetsmäklare beslut som kommer påverka det slutliga priset. Vilka typ av beslut som fattas beror sannolikt på vem som är beslutsfattare. Valet av fastighetsmäklare kan ha en påverkan på värderingen, då beslutsprocessen kan se olika ut hos fastighetsmäklarna. Syfte: Syftet med denna studie är att beskriva hur fastighetsmäklares beslutsprocess ser ut vid värdering av bostadsfastigheter och fastställande av utgångspris. För att sedan analysera om det finns skillnader i beslutsprocessen beroende på vem som värderar. Problemformulering: Hur ser fastighetsmäklares beslutsprocess ut vid värdering av bostadsfastigheter och fastställande av utgångspris, samt finns det skillnader i beslutsprocessen beroende på vem som värderar? Metod: Studien grundar sig på en abduktiv ansats då studien genomfördes med att först samla in teori om ämnet, för att sedan samla in empiri. Utifrån empirin kompletterades den teoretiska referensramen med ytterligare information. Vi valde att genomföra den kvalitativa metoden genom intervjuer med sju respondenter från olika områden för att täcka stora delar av västkusten, men också för att kunna göra en jämförelse mellan de olika respondenterna. Slutsats: Studien har lett fram till följande fem slutsatser; Slutsats 1: Fastighetsmäklares beslutsprocess följer beteendeperspektivet. Slutsats 2: Det finns inget som tyder på att det föreligger några skillnader i beslutsprocessen hos fastighetsmäklare. Slutsats 3: Läget är den främsta faktorn som beaktas vid värderingen. Slutsats 4: Beroende på var fastighetsmäklaren är verksam eftertraktar intressenter olika egenskaper. Slutsats 5: Fastighetsmäklarens erfarenhet och säljarens förväntningar kan vara avgörande för utgångspriset, men inte för värderingen. Nyckelbegrepp: Fastighetsmäklare, bostadsfastighet, beslutsprocess, värdering, värdehöjande faktorer, utgångspris.
Water Tree Mapping in Submarine High Voltage Cables Using Finite Element Method
No full textAbstract
Water treeing is a degradation phenomenon that occurs in submarine power cables. It is one of the main causes of failures of dynamic cables attached to mobile floating platforms. The rough sea environment causes mechanical stresses in the insulation of dynamic cables provoking appearance of microscopic cracks and water intrusion. The combination of water and enhanced electric fields can cause electrical, chemical, and mechanical reactions to occur which intensify water tree growth in cable insulation. This thesis aims to contribute to the development of a numerical model for simulating water treeing in high voltage insulating materials. The scope of the thesis is limited to the electrical aspects of the water treeing. COMSOL Multiphysics is used to model the conditions for experimental water tree testing according to ASTM D6097 standard. The model considers the current flow in the polymeric insulation due to the applied electric stress and so-called state variable is used to map healthy and damaged regions in the insulation material. The latter is identified as a domain where the electric field exceeds the threshold corresponding to initiation of defects in the polymer due to appearing internal electrostatic forces. Validation is done by comparing the simulation to the standard and experiments reported in the literature. The results show that the numerical model follows previous observations and may be used as a base for further development of the tools for predicting insulation lifetime
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
