Likviditetspremiens vara eller icke vara - Om likviditetspremiens existens på Stockholmsbörsen
Background: Operating on the stock market is associated with risks. If a particular asset is not traded with the same frequency as the average market asset, this particular asset is exposed to a liquidity risk. It means that the investor might not be able to sell the asset at a desired time without incurring expensive transaction costs. The query is whether or not the investor is compensated with a liquidity premium for bearing the extra risk. Earlier studies on the Stockholm Stock Exchange have failed to prove that there is a relation between stock return and liquidity.
Gymnasielärares icke verbala kommunikation i klassrummet
This paper compares and discusses teachers´ nonverbal communication in the classroom. The purpose of the study is to find out what the teachers´ nonverbal communication looks like in the classroom and with that information increase teachers´ awareness of nonverbal communi-cation and its impact on the teaching. Ten teachers at the upper secondary school have been observed for twenty minutes when having a lecture. The result shows that the most common nonverbal expressions are hand and arm gestures used to enhance what is said by the teacher. The result also shows that the nonverbal communication is similar with all observed teachers.
På vandring mot handling : Utbyte av perspektiv i landskapet
Sustainable Development is often described as a balance between ecological, economical and social aspects. Between these exists a complicated interaction that creates conflicts in the planning of the landscape. We see a growing need for a functional interaction between values and interest and an understanding for different perspectives. Cooperation and dialogue are key ideas with the focus on cooperation rather than the goal. There is a lack of forum for dialogue and cooperation within municipalities where a great knowledge and competence are gathered.
Terminallokalisering med tyngdpunktsberäkning och kostnadsanalys
The Kedertruss is the loadbearing part in the Keder weatherprotectionsystem and it has been analyzed concerning its loadbearing capacity. The Kedertruss is produced and manufactured by Wilhelm Layher GmbH & Co. KG and this report has been made for their Swedish division Layher AB. The Kedertruss, designed in Germany according to German designcode, has been recalculated concerning Swedish conditions according to Eurocodes and a ongoing European standardization project. The two-dimensional program Winstatik Frame Analysis has been used for evaluation of load effects. Capacity has been calculated by hand-calculations and it has been verified that the Kedertruss in its larger spans isn?t able to withstand the loads.
Ställtidsreducering med hjälp av SMED i pressgjuterianläggningar
To maintain production in high salaries countries and strength in competition against other companies, it is today more important than ever to maximize production, offer a wide spectra of products and be able to deliver on the customers desire of shorter and shorter delivery time. Flexible production and short time spent on die changes is vital to achieve these desires. The interest for die changeover time reduction grew in the same pace as the demand for increased product variety grew. SMED as a method of reducing time spent on die changeovers were developed in between 1950-1970, by the Japanese Shigeo Shingo.The purpose of this thesis work has been to investigate the result of SMED in a die casting facility, and compare the result from it with the result considering time spent on die changeovers when investing in new equipment. The goal is to implement a thorough investigation by using the SMED method at Tenhults Pressgjuteri AB and make a brochure that have to be simple to understand, in purpose to draw interest to the advantages of using SMED as a method.Commissioned by the Swedish foundry association Swecast, the work has been carried out by studying die changeovers at Tenhults Pressgjuteri AB, where filming and interviews with the operators have been included in the analysis.
Att leda löshästar : En studie om hur resurskonsulter upplever ledarskapet på kundföretagen
SammanfattningTitel:Att leda löshästar - en studie om hur resurskonsulter upplever ledarskapet ikundföretagenNivå:C-uppsats i ämnet företagsekonomiFörfattare:Sabina Molin och Kamilla KristofferssonHandledare:Monika Wallmon och Lars EkstrandDatum:2015 ? JanuariSyfte:Syftet med detta arbete är att med hjälp av leader-member exchange theory undersökautbytesrelationerna mellan resurskonsulter och deras närmaste ledare på kundföretaget samtvilka ledarbeteenden som används för att leda inhyrd arbetskraft och hur de påverkarrelationerna.Metod:Denna uppsats har ett positivistiskt förhållningssätt och det används en hypotetiskdeduktivmetod som innebär att hypoteser deduceras från teori och sedan prövas mot empiri.En kvantitativ ansats används genom att samla in empiri genom webbenkäter som skickades uttill 148 respondenter.Resultat & slutsats:Undersökningen visade att stödjande ledarskap och leda som förebildhade störst påverkan på utbytesrelationerna. De ledarbeteenden som användes i störstutsträckning var berättigande och erkännande. Utveckling och visionerande användes allraminst. De flesta utbytesrelationer var höga.Förslag till fortsatt forskning:Flera förslag till fortsatt forskning presenteras men vi finner attundersöka både ledare, ordinarie och inhyrd personal för att jämföra hur ledarskapet se ut ochfå en bredare bild är främsta intresset.Uppsatsens bidrag:Denna uppsats har bidragit med en insyn i hur ledare leder inhyrd personaloch hur detta ledarskap ser ut i form av ledarbeteenden och utbytesrelationer.Nyckelord:Ledarskap, inhyrd personal, utbytesrelation, leader-member exchange theory,ledarbeteende, transformativt och transaktionellt ledarskap..
Hur enkel- & dubbelportsturbin i kombination med två olika avgassamlare påverkar gasväxlingsprestanda på en Scania V8
The exhaust arrangement on a Scania V8 consists of one manifold at each bank connected to a twin entry turbine (8-2-2). A study in GT-Power has shown improved performance and reduced cylinder to cylinder variations using two manifolds at each bank in combination with a single entry turbine (8-4-1). This thesis work analyses the difference in performance shown in simulation and verify it by engine test.The initial work was focused on simulation in GT-Power. Investigating how exhaust manifold volume and pulses effects the turbine efficiency and the mean effective pressure during the gas exchange. To verify GT-Power simulations four engine tests with different exhaust arrangement have been made.The results from GT-Power simulation indicate that a larger exhaust volume improve the turbine efficiency.

Flödesoptimering i begränsande resurs
Most companies have a bottleneck in their production, that is a constraining re-source. When the demand is higher than the capacity in the constraining resource it is impossible to produce the demanded output. This problem leads to delayed deliveries, unhappy customers and ultimately to decreased revenue. Bottlenecks therefore has a significant role in production and must be handled thereof.MW Power in Sävsjö, Sweden designs and manufactures water and steam boilers for the customer's unique needs. MW Power invested in a new plasma cutting ma-chine but the machine has not reached the expected capacity.
Empiriska växelkursmodeller för den svenska kronan - Är det någon som fungerar?
The forecast ability of four well-known exchange rate models for theSwedish krona is tested in this thesis. The models that are tested arethe purchase power parity, the real interest differential model, thesticky-price model and a productivity model. In addition to thebenchmark, the random walk, they are also compared to each other.They are all tested on three different horizons one quarter, two quartersand four quarters. The mean squared forecast error criteria and thedirection of change criteria are used for evaluation of the forecastability. Only in a couple of cases are the forecast ability of thetheoretical based models significant better than the random walk..
Avskiljning av ammoniumkväve och fosfatfosfor i reaktiva filtermaterial : skak- och kolonnförsök

Effektivitetsparadoxen - En eventstudie av handelsstopp på Stockholmsbörsen mellan 2003 och 2008
A trading halt is a measure conducted by a securities exchange in order to reduce information imbalances between market participants, thus enabling a higher level of market efficiency. A market is said to be efficient when new information concerning a company is instantly reflected in its stock price, implying that abnormal stock returns cannot be systematically achieved in an efficient market. The purpose of this study is to examine the occurrence of abnormal stock returns following trading halts on the Stockholm Stock Exchange. The study is based on a sample of 64 trading halts executed between January 2003 and February 2008. Historical daily prices for stocks subject to trading halts during the period have been gathered from the Datastream Advance database, while information on date and time of trading halts have been collected from the Stockholm Stock Exchange website.
