Altmetri ? ett delfält i utveckling
Altmetrics, a subfield of informetrics, is still in development. The aim of this thesis is to explore; the significance altmetrics may have in the LIS field, and to define the new perspectives altmetrics offer in comparison to traditional metrics. The research questions are:- How can altmetrics affect research assessment?- How does altmetrics position itself towards traditional metrics?- How could altmetrics influence the LIS field?A qualitative content analysis was used as a method. The analysis of a sample of ten peer reviewed articles was based on a coding scheme with eleven codes.
Se inte ner på golvmarknadsföring! - En kvantitativ studie om effekter av golvmarknadsföring i köpcentrummiljöer
Shopping malls have been growing in numbers during the last few decades. As an effect, consumers are increasingly placing a greater amount of their purchases under one roof. The problem is that stores within these malls have to fight for the consumers' attention in competition with all the other stores. Thus, making consumers noticing their store is critical for success. Creating attention through floor advertising could be a potential way of doing so.
Ersättningsmodeller för ballasttransporter : vid anläggning och underhåll av skogsbilvägar
Construction and maintenance of forest truck roads are a necessary element of industrial forestry. Payment for contracting services in this context can be done according to a number of payment models. This study will focus on the methods and consequences associated with a change of Holmen Skog?s payment model from per hour to per metric ton for ballast hauling.
The aim of this study is to improve the economic efficiency of Holmen Skog?s ballast hauling in construction and maintenance of forest truck roads. This is done by formulating and evaluating a proposal for a payment model based on crowns per ton.
Conscientiousness, Locus of Control och Arbetsmotivation
Studien syftade till att undersöka om det finns samband mellan conscientiousness, Locus of Control och arbetsmotivation samt om ålder och anställningslängd predicerar en del av ar-betsmotivation. Studien omfattade 63 anställda (28 kvinnor och 35 män) på ett telekommuni-kationsföretag i Sverige. För att studera conscientiousness användes ett egenformulerat test med god intern homogenitet, Cronbachs alfa = 0,85. För att mäta Locus of Control och ar-betsmotivation användes redan konstruerade test med god validitet och reliabilitet, skapade av Rotter (1966) och Cammann, Fichman, Jenkins och Klesh (i Bowling & Hammond 2008). I den statistiska prövningen användes både bivariat korrelation i form av Spearmans rho och MRA-standard och hierarkisk.
The development of CRITA-Score ? A hybrid credit rating model for predicting financial distress
Large companies in today?s business environment are to a great extent depending on their credit score by rating institutes like Moody?s and Standard & Poor?s. There is however indications that these big institutes are not always rating companies accurately. This is why this thesis aims at developing a new credit rating model, CRITA-Score, with the objective of determining a company?s financial health more accurately.
Dimensionering av industrilager för biobränsle :
The aim of this study was to develop a simple model for calculating stock costs for bio fuel at Billerud Karlsborg and subsequently recommending a suitable stock level of bio fuel. The stock components considered in the model are GROT (branches and tops), bark, dry wood chips, raw wood chips from barking and sawdust. The calculations are based on a probability distribution of historical deviations between ordered and delivered volumes. The model presents two different ways to manage the supply in case of irregular deliveries. The first way is to stock enough volume to cover the deviations and the second way is to compensate with a quick purchase from the spot market (at extra high purchase prices).
Utredning av undervattensbastu
Nordic Marine Sauna AB has, since 2005, designed, manufactured and sold floating saunas. Theproduct are characterised by a well thought thru and appealing design and its high quality. Thecompany is now intending to open a new business area by starting a subsidiary, NordicSubmarine Sauna AB, which will design submerged saunas. The expected customers are leisureand conference centres as well as customers that seek an experience out of the ordinary.Due to the products technical complexity a master thesis was adverted. The task was to do aninvestigation whether such a product is technically viable.The job involved research of existing products and constructions material as well as designingthe product with CAD and FEM-programs.
Estimation av bostadsrättspriser i Stockholms innerstad medelst multipel regressionsanalys.
This report aims to study the condominium prices in central Stockholm and the factors thataffect these prices. A linear regression model was set up and data about relevant covariatessuch as floor area, mortgage rates and where the condominium is situated were gathered toassess if and how they influence the price. The raw data was processed and enhanced to gain asmuch relevant information as possible to the model. To determine the covariates? influence onthe final price, regressions were ran and various tests were performed on the output data.
"Storebror" kommer till stan? En diskursanalytisk studie av debatten kring kameraövervakning av "Stråket" i Malmö
Social control in different forms has existed in all known societies. This control has taken different shapes and expressions. In older smaller communities there was a collective control among the citizens. In modern societies the state is trying to control the lives of the citizens. These control mechanisms can be seen as both freedom-reducing and freedom inducing depending on which concept of freedom one upholds.
Inverkan av leasingklassificering på konkursrisk - en studie av hur redovisningsbaserade prediktionsmodeller påverkas av en ny leasingstandard
The purpose of this bachelor-thesis is to investigate the possible effects of lease accounting on the estimation of bankruptcy. This is done by estimating the risk via prediction models based on accounting ratios for a sample of 43 listed firms in Sweden. Estimation is conducted twice for each firm, once base on unadjusted data as it is presented in the annual report of 2012, and one with data adjusted for operational leases (that is data is treated as if all leases present were to have been reported as financial leases). In the next step it is tested weather the predictive ability of the models is affected by this adjustment or not. For this purpose translation of bankruptcy risk into synthetic credit ratings via interest coverage ratios is done.
Ung och arbetslös idag : Några arbetslösa ungdomars upplevelse av arbetslöshet
Syftet med föreliggande undersökning är att få kunskap om hur några arbetslösa ungdomar upplever sin situation som arbetslös, vilket studeras med fokus på framtidstro, sin egen förmåga/kompetens till att påverka möjligheterna att få jobb samt vilka faktorer de upplever är viktiga när det gäller att få ett jobb inom en snar framtid. Detta studeras utifrån teorierna om locus of control och self-efficacy. Två tjejer och fem killar i åldrarna 16-24 år, samtliga arbetslösa och inskrivna på Ungdomskraft, deltog i semistrukturerade intervjuer. Resultatet visade att majoriteten av ungdomarna har en hög tilltro till sina egna resurser och upplever att de själva har kontroll över sin situation som arbetslös. Vidare visade resultaten på ett mönster mellan intern locus of control och hög self-efficacy i samband med en positiv framtidstro med avseende på att få ett jobb..
Lyckans land? : En ekonometrisk studie över nationshemvistens påverkan på upplevd lycka.
Does the country people live in affect the probability of them experiencing happiness? Can a country variable in an ordinal regression model be affected when microeconomic and macroeconomic factors are added to the model? The possible outcomes are either that the country variable affects less when the additional predictors are added to the model, or that they stay the same. The micro data is collected from the European Social Survey database, the macro data is collected from the World Bank. The country variable becomes less substantial when additional variables are added to the model. The variable with the most influence over expected happiness apart from the country variable is whether the individual often socializes with friends or not.

In the recent years auditing scandals all around the world, deficient internal control has attracted a lot of attention. This has contributed to further requirements on insight and internal control. Those scandals have seriously damaged the auditor?s profession and contributed to a reduced trust among the public. Therefore an extensive work to recover and stringed the trust was started all around the world.
Modellering och simulering av hovrande helikopter
At the department of Electronic Warfare Assessments at the Swedish Defence Research Agency in Linköping one of the activities is modelling and simulation of the duel between a robot and a target. The aim with this Master's thesis is to develop a simulation model of an hovering helicopter. First a theoretical description of the forces and moments acting on an helicopter is given. Then the equations of motion are derived. These equations are simplified to be valid only for a hovering helicopter and the result is a mathematical model.
Flervariabel reglering av industrirobot
The goal of this Master thesis has on the one hand been to create a simulation environment for robots, where not only the simulations in this work can be performed, but also similar robot simulations, and on the other hand to study regulators that can increase the possibilities of rejecting disturbances on an industrial robot. The robot model used has three degrees of freedom, corresponding to the three main links on ABB:s IRB7600. The simulation environment is created using Matlab, Simulink, and Robotics Toolbox. It is constructed in a general way and can be used for simulations of other robot objects created in Robotics Toolbox. A gain scheduling is added to the LQ-regulator, where the feedback matrix is varied depending on the arm position in the workspace.
