The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive. The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of association analyses.

Wireless sensor networks have the potential for becoming a huge market. Ericsson predicts 50 billion devices interconnected to the Internet by the year 2020. Before that, the devices must be made to be able to withstand years of usage without having to change power source as that would be too costly. These devices are typically small, inexpensive and severally resource constrained. Communication is mainly wireless, and the wireless transceiver on the node is typically the most power hungry component.

The aim of this thesis is to analyze and explain the similarities and differences in management control between a private and a public primary care company. A comparative case study was developed based on one public and one private primary care company in Stockholm County Council. The framework of Otley (1999) was used to define and limit the area of management control systems, according to his five factors. For the analysis of the empirical results Hood's (1995) seven doctrines of New Public Management was applied, and customized to fit the purpose of the study. The results indicate that the differences between the two organizations are very limited.

During the last decades, brand equity has been a priority topic for both practitioners and academics. In accordance with the structural changes in the economic settings caused by the so-called "new economy", corporations being confronted with a shift on perceived business value structure from tangible assets to intangibles. On the other hand firms increasingly are adopting more responsible behaviour towards their societies. In this context, one critical question is to understand how corporate conduct may affect brand equity. The purpose of this study was to find how brand equity (BE) measurement methods embrace corporate responsibility (CR), based on a literature review.

Avsikten med denna studie var att undersöka om generell begåvning (GMA) och personlighetsdragen i femfaktormodellen (FFM) kan predicera arbetsprestation bland konsulter. Tidigare studier har visat att mätningar av GMA och personlighetsfaktorerna i FFM, i synnerhet samvetsgrannhet, är framgångsrika variabler att testa för i rekryterings- och urvalssammanhang. Predicting Job Performance, PJP, är ett psykometriskt test som integrerat mäter personlighetsfaktorer i FFM samt GMA. PJP har genomförts av 26 verksamma konsulter på ett specifikt företag för uppskattning av faktorerna. Vid en multipel regressionsanalys erhölls inga signifikanta värden mellan faktorerna i PJP och arbetsprestationsmåttet.

This master thesis states the following questions: Is it easy or difficult to retrive information from a mobile phone manual? How can the search process be described among user for a mobile phone manual? What similarities and differeces can be identified between users? Arhe there any variables that affect search performance such as reading skills or technical domain knowledge? Eight mobile phone users participated in an empirical observation and the scope was to find information in a paper version of a mobile phone manual according to given tasks. The results shows that some users has problems to retrieve information due to that the correct page in the mobile phone manual could not be located. The results show that the user is using several search strategies, for example the table of contents and the index, when trying to locate information. The results also revel that the user initiates multiple search steps before the correct information can be located.

Motivation är ett centralt begrepp inom psykologisk forskning och är väsentligt i organisationer för att skapa förståelse om hur aktiviteter på arbetet påverkar anställdas motivation och prestation. Motivationsfaktorer förklaras bero på både inre och yttre drivkrafter. De inre drivkrafterna styrs av individens intressen och tillfredsställelse i arbetsuppgifter på arbetet, medan de yttre förklaras som exempelvis belöning och att uppnå företagsmål. Denna studie bygger på åtta intervjuer där syftet var att undersöka subjektiva upplevelser av inre och yttre motivation på arbetsplatsen. Resultatet analyserades med hjälp av metoden meningskoncentrering vilket uppvisade 4 teman i faktorn inre motivation: frihet, välbefinnande, mål och delaktighet.

The purpose of this study has been to examine how Afro-Cuban musical traditions and concepts are integrated in compositions for solo guitar by the Cuban guitarist and composer Ñico Rojas and how this can be expressed in the performance of his music by a classical guitarist. For this purpose a guide to Rojas music, which is included in this report, was written based on literature about Afro-Cuban music. Then a classical guitarist learned to play a piece by Rojas with help from the written guide. The result was examined using recordings of the guitarist's interpretations and an interview with him. The conclusion is that different aspects of the Afro Cuban musical tradition are present in Rojas? music, but that the concept of the clave was the most useful aspect for the classical guitarist that interpreted the music of Ñico Rojas in this study..

Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

There has been an increase in the importance and amount of information concerning publicly traded stocks in recent years. When analyzing and valuing stocks finding new ways of collecting information has therefore increased in importance. This thesis aims to explore how meetings with management can impact the stock valuation done by the security analysts. Furthermore the case study examines what kind of information analysts can receive by interpreting management at these meetings. This case study of ten Swedish security analysts show that the analyst?s stock valuation is directly or indirectly affected by the meetings.

För många är arbetet den mest centrala delen ilivet där de flesta av dygnets vakna timmar spenderas. Studiens syfte var attundersöka yrkesstolthet och identifikation med arbetet.

Ett heterogent urval användes föratt få en så stor variation som möjligt. Resultaten visade att den viktigastekomponenten för yrkesstolthet var upplevelsen av att få göra gott i mötet medandra människor samt att arbetet känns meningsfullt.

Background: Relatives are those persons who are closest to the patient, regardless of relationship and included into the patient´s life world. When a person is in a palliative stage this affects not only the patient but also the relatives, as it implies such a big change in life for all. The nurse has an important role for both the patient and the relatives. Aim: The aim is to highlight the relative´s needs of support for palliative care. Method: A literature review based on previous research. Ten articles were found, nine with a qualitative approach and one with both qualitative and quantitative approach. Results: The analysis resulted in six themes, these were the result of the study. The six themes were, ?to be seen an confirmed?, ?good communication?, ?continuous information?, ?availability and continuity?, ?to participate? and ?to share responsibility with the staff?. Conclusion: As a nurse we come in contact with relatives of patients in a palliative setting in any form.

Species that have a high degree of specialization and poor dispersal ability can be more prone to extinction than more generalist species and good dispersers. How these species traits affect the viability of populations is dependent on landscape factors,such as isolation and connectivity. Additionally, interactions between species (e.g. symbiosis), and how these interactions vary spatially and temporally can have a large impact on populations. When the range and habitat areas of a species continuously decrease, management strategies are often needed if the species shall be able to survive.
