Since the nineties the words customer, effectiveness and quality have become part of everyday school life. Municipalities? makes regular customer surveys to measure both independent schools as municipal schools ' quality. A common method for customer research and background studies is that parents and students are asked to respond to simple Web-based surveys. Customer satisfaction and/or customer dissatisfaction options are presented in tabular form, based on the percentage that expresses a particular position within a query.

Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.

Background and problem: Whether or not the pay to executives is fair is widely debated. During the last years especially the variable pay has been in the spotlight. But at what levels are the compensations really at? Media?s focus is mainly on the absolute highest compensations which may result in a skew view on pay-for-performance incentives.Purpose: The purpose of this thesis is to establish the levels of compensation to executives in a wide range of randomly selected companies listed on the Stockholm stock exchange during the years 2001 to 2005. Furthermore, the impact of a set of firm specific variables on compensation levels will be analyzed with basis in several hypothesis.Delimitations: The variable pay considered in this thesis will only be variable cash bonuses.

It is not uncommon for math difficulties and reading difficulties to occur simultaneously. Despite this, math and reading difficulties are thought to have different cognitive profiles where math difficulties are linked to number sense; an innate ability to understand, approximate and manipulate both quantities and numerical information, whereas reading difficulties are linked to phonological ability; an innate ability to understand, create representations of and manipulate phonological information. A possible link between the difficulties is that phonological abilities also could affect mathematical ability. Support for this comes from studies where comorbid math and reading difficulties are associated with more severe difficulties in arithmetic ability compared to those with isolated math difficulties. The purpose of this study is to examine whether isolated math difficulties, isolated reading difficulties and comorbid math and reading difficulties can be linked to deficits in number sense, phonological ability or both of these, and whether comorbid math and reading difficulties differ in performance in mathematical tasks compared to isolated math difficulties for children in second grade.

Three different factors are thought to be involved in the increased segregation in Stockholm: the living segregation, scientific and political dissonances and the social economical factor. Many segregated areas have many inhabitants with foreign background. Schools in these areas have a higher number of students with lower grades compared to other schools with higher number of students that are ethnical Swedes. Jordbromalmsskolan is a school in Haninge kommun that is one of the seven schools in Stockholms suburbs where students graduate with the lowest grades. The school is suffering from a very bad reputation because of many problems like fights between students and lack of resources like purchase stop.

Tvättrådsetiketter är en relativt liten detalj på plagg, som dock har en stor betydelse för plaggets livslängd och dess miljöpåverkan. De flesta har nog upplevt att en tvättrådsetikett har blivit oläslig i ett plagg. Det är viktigt att etiketten förblir läslig under hela plaggets livslängd, för att skötseln av plagget ska utföras på ett korrekt sättoch med en så liten inverkan på miljön som möjligt. Därför har kvalitén på ett antal etiketter av olika material och olika framställningsmetoder testats. Det för att sevilken av dessa som är det bästa alternativet kvalitets- och miljömässigt.

Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.

In society and school today there is a major focus on assessment, and this can for example be seen in an increased research on assessment over the last ten years. But one research topic still quite unexplored is how students perceive assessment. The main purpose with this study is to explore students? experiences of assessment, how assessment interferes with their volition and if the extent of the impact on the motivation varies depending on how the assessment is performed. In order to answer these questions a quantitative investigation was performed at first. 83 students answered a questionnaire about what kind of assessment they experience in school, if they receive feedback, what is important for being successful in school, if they know on what grounds they are assessed, what impact failure and/or success has on their motivation, if they are stressed by school etc.

Product development is a risky business; many products never yield profit, but it is also ne-cessary for a company?s survival in a competitive business where the costumers change their requests constantly. Consumer-led product development is developed from the wish to fill the consumer?s needs and expectations and thereby be more likely to succeed. Lindell?s Gårdsslakteri AB is a local slaughter and meat processor in Västergötland.

This thesis has been performed at Scania CV AB Technical Centre in Södertälje and its aim hasbeen to study the causes and effects of deformations in the interface between the rear axlehousing ADA1100 and the central gear house R780 during operation. Design changes that wouldincrease the sealing capability of the studied interface are also suggested. Finite element (FE)and CAD software have been the primary tools in this study.Finite element (FE) simulations are used in the industry to predict and develop engineeringdesigns. The main motive for FE simulations has traditionally been to identify weak spots in thedesign, regarding high tensions and large deformations.The FE model is an aggregation of submodels and interface models that represents the rear axlehousing, suspension, central gear, central gear housing, wheels, bolts and weldings, and theirinteractions. The submodels have different material properties and they are connected withcontact interface models.Boundary conditions are defined on the bushings in front of the rear axle and on the air bellowsbehind the rear axle.

SammanfattningSyfte och frågeställningarStudiens huvudsyfte har varit att öka kunskapen kring de elever som väljer att inte delta på idrottsundervisningen. Vidare har syftet varit att försöka utläsa skillnader och likheter mellan de elever på en gymnasieskola som läser idrott och hälsa i ordinarie grupp och elever på samma skola som valt att läsa ämnet i mindre grupp.Utifrån syftet har följande frågeställningar formulerats:? Hur beskriver gymnasieeleverna i de olika grupperna sina erfarenheter och upplevelser av idrottsundervisningen, motion på fritiden, utbildning och upplevd hälsa?? Vilka skäl kan enligt läraren till den mindre gruppen finnas till att elever inte deltar i den ordinarie idrottsundervisningen i den undersökta skolan och vad kan göras annorlunda?MetodDe metoder som valdes utifrån studiens syfte var såväl av kvantitativt som kvalitativt slag.Med en kombination av metoderna såg vi det som en möjlighet att belysa fler aspekter av problemområdet. En enkätstudie har genomförts med 90 gymnasieelever i södra Stockholm.Urvalet bestod av två grupper. 60 elever som deltar i den ordinarie idrottsundervisningen, och 30 som går i gruppen som benämns med namnet idrott och hälsa i mindre grupp.

Migration and giving birth are crucial decisions for animals during their life cycle, which may have lasting consequences on their population demography and fitness. Migration can entail a variety of possible effects for an individual, such as access to high quality food and reduced risk for predation. The moose (Alces alces) in northern Sweden is partially migratory and moose females are known to give birth to one or two calves. The synchrony between time of calving and timing of migration has not been compared before, especially in terms of energy maximizing and time minimizing perspectives, which may provide vital cues for fitness benefits of migration. I investigated effect of timing of birth and individual life history on distance, timing, stopovers and duration of 190 individually marked female moose that have been tracked for multiple years in ten different areas in northern Sweden.

Background and problem discussion: Sustainability reporting has recently risen in importance and a rising number of companies choose to issue voluntary stand-alone sustainability reports. Their non-regulated nature increases the opportunity for management to angle the information in these disclosures to their own advantage. Lately the focus has shifted from examining what kind of information is provided in environmental disclosures, to analyzing how the information is presented.Purpose: The purpose is to examine if managers in the energy sector use optimistic tone when issuing sustainability reports. The aim is to find out if the tone applied in environmental disclosures is in congruence with either the environmental or economic performance or if an excessively positive tone is being used to mislead readers.Limitations: This study is limited to information found in environmental disclosures from private companies in the energy sector, issued in 2012 or 2013. Environmental performance is defined as the amount of CO2e emissions and economic performance refers to annual company revenues.Methodology: The quantification of optimistic tone is conducted using a content analysis, relying on a pre-specified wordlist and a pilot study.
