Tillförlitlighet för automatiska sprinkleranläggningar - en analys av befintlig statistik

In this report statistics concerning the Reliability of sprinkler systems from seven countries has been analysed. The objective of the report has been to determine the Reliability of sprinkler systems in Sweden and to present suggestions on measures to increase the Reliability. The main conclusion that has been drawn is that the Reliability of sprinkler systems in Sweden is 92 percent according to the analysis of Swedish statistics, and that this figure finds support in statistics from other countries. Further results are that the quality of design, installation, maintenance and inspection of sprinkler has to be improved and that the Swedish incident report has to be revised..

Prövning av måttet Läpp-till-Lyft (L-t-L) på vuxna utan sväljsvårigheter

Context: Lip-to-Lift (L-t-L) is a bedside-method for measuring oral transit time at swallow. It was designed for a swallowing examination of persons on nursing homes where weight loss was noted in people with average L-t-L-time >5 seconds (Sandin, 2005). The measurement was validated and evaluated by Eriksson, Bremer Zerpe (2008).Objectives: The study objective was to examine L-t-L on a group of young adults without swallowing disorders and as to examine the inter- and intra-judgeReliability of the measure.Questions:What is the L-t-L-time for young adults without swallowing disorders?Are there any gender differences regarding L-t-L-time?How high is the inter/intra-judge Reliability of L-t-L?Method: Examination of L-t-L-time was carried out on 20 young adults, aged 19-27 years, without swallowing disorders after Sandin?s (2005) instructions. Measurements of 20 swallows per person were made.Results: The average L-t-L-time of young adults without deglutition-difficulties was 1.13 seconds (sd =.14).

Klassificering och värdering av finansiella instrument : Ett tillförlitlighetsperspektiv

During the financial crisis voices were raised towards the regulatory framework IAS 39 recognition and measurement of financial instruments and pointed out that it was inadequate. The complexity of the framework contributed to the fact that it was difficult to apply. IASB accelerated the modeling of the new to be regulatory framework IFRS 9. In this study we will focus on the Reliability of accounting information, which is an important aspect from the stakeholder?s point of view, for example, to be able to make the best decisions the accounting information should be proper.

Problem vid fastställandet av verkligt värde, tillvägagångssätt och tillförlitlighet i fastighetsvärdering

This thesis aims to examine problems that occur when determining the fair value of investment properties. It also takes into consideration the Reliability and relevance of the reported fair values on behalf of the key stakeholders. The study has been conducted by interviewing representatives at real estate and external valuation companies. The study shows that there is a need for assessments in the valuation process and that real estate companies have room for their own interpretations. The conclusion is that determining fair value is an estimate, not a fact.

Tillförlitlighet i Stockholms elnät : En analys med hjälp av Tekla NIS

Outages in the electric grid can be costly for society. Because of this, Reliability is one of the parameters used to regulate network companies. Reliability in electrical grids can be measured with SAIDI, system average interruption duration index, which for Fortum Distribution has increased in Stockholm?s distribution network (11 kV) in the early 2000?s.By using outage data for Stockholm from 2011-2013, sets of parameters to be used for Reliability calculations in the network information program Tekla NIS were derived. Two different options for investment were then analysed: changing old cables with high fault frequencies, and installing automatic switching in distribution substations.

Perceptuell bedömning av dysartri: jämförelse av detaljerad kontra övergripande analys

The aim of the present study was to compare two differenttypes of assessment of dysarthria to be able to conclude which methodmight be more suitable for use in research and in clinical practice.Five speech pathologists with extensive experience assessed 20different recordings of individuals with dysarthric speech using twodifferent forms, one more detailed and one designed for a more overallassessment. In the detailed form 30 aspects of voice and speech wereanalyzed. In the short form 5 overall aspects of voice and speech wereanalyzed. Six of the recordings were duplicated to serve forassessment intra-judge Reliability for each form. The results show thatthere was a high correlation between the two forms and that theymeasures the same types of speech deviations although on differentlevels of details.

Stuttering Severity Instrument 3: Svensk översättning och utprövning

The main purpose of this study was to translate Stuttering Severity Instrument 3 and to evaluate its Reliability and validity. Five speech-language pathologists assessed 35 adults who stutter with this assessment tool. Overall the results showed a very high inter- and intrarater Reliability. A highly significant correlation between Stuttering Severity Instrument 3 and ratings of severity, made by the speech-language pathologists, strengthen the validityof Stuttering Severity Instrument 3. No correlation was found between the total score of Stuttering Severity Instrument 3 and the self-report measure Overall Assessment of the Speaker's Experience of Stuttering, whichindicates a lack of social validity in Stuttering Severity Instrument 3.

Validering av smärtformulär för katt

The objective of this study was to assess validity and Reliability for five different owner-completed instruments evaluated to assess chronic musculoskeletal pain in cats. All of the instruments were questionnaires, three asking about behavioral changes, one about the degree of pain and one about quality of life. One of the instruments was written originally in Swedish, the other four instruments were translated into Swedish before use. Data available were records from 57 cats with no signs of pain and 11 cats with different pain-related diagnoses. The diagnoses were ensured by clinical examination including palpation and manipulation of joints, gait testing on a force-plate and X-ray scans. Instrument 1 was completed by 57 pain-free and 11 pain-affected cats.

Att arbeta med ständig osäkerhet : En studie av High Reliability Organization

There are certain organizations that manage to handle risk in such a successful way that they almost stay error-free, in spite of the fact that they daily face the risks of accidents. These organizations are usually given the name High Reliability Organizations (HRO). While the most common example is that of a nuclear plant the variety of what organizations can fit into the category is extensive.The purpose of this study is to describe safety culture and theories about HRO and how these can be found in practise within an organization.This qualitative research uses influences of ethnography in its method. The ethnographical approach was picked due to the field of the study and the cultural context in which it is set.The results of the study identify a number of elements sorted into four themes. These themes are deemed compatible or non-compatible with relevant existing theories.

Redovisning till verkligt värde: Tillämpningen av IAS 40 i svenska fastighetsbolag

The aim of our master thesis is to study the way valuation of real estate is conducted by real estate companies. Furthermore we want to identify the factors that affect the relevance and Reliability of the valuation. The reason for this is the introduction of IFRS, in 2005, and the application of the IAS 40 rules stating that real estate are to be recognized at fair value on the balance sheet. To do this we have performed a case study on 10 Swedish real estate compa-nies listed on the Stockholm stock exchange, OMX, Large Cap and Mid Cap list to see how the share value has performed in relation to the reported net asset value since 2005 and how they value their collection of properties. We also studied the assumptions made by real estate company analysts.

Vad påverkar en aktieanalystillförlitlighet? : En kvantitativ studie om relationen mellan tillförlitligheteni en aktieanalys och dess innehåll.

A debate in finance is whether a random investment gives the same return as carefully choose and valuing an amount of shares to invest in. Stock valuating Stock valuation is often done by fundamental valuation models, based on the company's underlying character, which tries to put a correct price on the stock. Today there are several different valuation models that can be used for this purpose. Since valuation models are only mathematical, equity research is underpinned by more subjective assessments about the company and its future.The purpose with this thesis is to describe which valuation models that are used by professional stock analysts, but also to see if the Reliability on the equity research is affected by the used model to valuing the company. Furthermore, we want to see if the job that?s been done to understand the company, measured by the equity research quality, impact the Reliability on the equity research.In this thesis, we have, to achieve our purpose, conducted a quantitative content analysis of 164 equity research done by professional analysts at firms listed on the Stockholm Stock Exchange. With basis in previous research, we have developed a method for determining the valuation model that is used in the equity research, the Reliability on the equity research and a framework for assessing the quality of the equity research.In the theoretical framework the valuation models involved in our study are described, previous research on the Reliability on the equity research and their practical use.

Hur olika skogsägarkategorier har försett sig med underlag för beslut och åtgärder efter stormen Gudrun : en jämförelse av medlemmar och icke-medlemmar, åbor och utbor samt kvinnor och män

During the 8th and 9th of January 2005 a devastating storm named Gudrun entered the south of Sweden and a big part of the forest owners got their forests damaged. The study objective was to investigate on which basis and how the affected forest owners made their managment decisions immediately after the storm and if there are any differences between different categories of forest owners. - Members ? non members in a forest owner association (FOA) - Resident owners ? non resident owners - Female and male forest owner The study is based on a questionnaire survey with the purpose to examine the most important counsellor and information channels of the forest owners. A total of 450 forest owners participated in the survey. Results show that all categories of forest owners prefer professional counselling rather than personal counselling.

Är vinkritik nonsens - En explorativ studie av vinkritiker och deras bedömningsprocess i en kluven industri

With increasing wine consumption and a growing assortment at available to Swedish consumers, there is an interest in understanding the decision making process of Swedish wine consumers. In this thesis the expert phenomenon is studied with respect to wine through wine critic Reliability: grading objectivity, understanding the process of wine criticism and possible critic influence on consumer behavior. Two studies were performed; a qualitative in-depth session of interviews with industry connoisseurs and a quantitative analysis of 589 online wine reviews. Our results indicate that wine reviews are highly subjective and defy prediction through analysis of external variables. Critics are likely to judge differently based on what information they have at hand, suggesting that expectations affect grading.
