The concept of function represents a major part of mathematics and becomes more significant in school during high school. Throughout history, it has been a difficult concept to define and may create challenges for contemporary students. This literature study aims to identify students' difficulties with the concept of function, as well as to account for how the definition of a function has evolved historically. The literature study has been conducted through database searches in ERIC, Education Research Complete and MathSciNet via EBSCOhost, as well as through chain searching. The study results in identifying that students' difficulties with the concept of function primarily include the graphical and algebraic forms of representation.

BackgroundThe opportunity for cochlear implantation has now extended beyond children who are only deaf or hard of hearing. Children who are deaf blind from birth or early in life are receiving implants, but very limited research has been done for this population, and this raises important issues. AimThe aim of this study was to estimate the prevalence of hearing and vision impairment or deaf blindness in children with Cochlear Implants in Sweden and to investigate the diagnoses issues among these groups of subjects. Material and MethodSubjects with an age between 1-18 years were ascertained through multiple sources and almost complete ascertainment was achieved.ResultsA total of 77 subjects with a referring diagnosis of combined hearing and vision disorder or deaf blindness were ascertained. Out of those, 30 subjects were excluded.

Since their invention in 1999, CubeSats have become a widespread standard for small picosatellite missions. CubeSats allow for quick development of satellite payloads and launch in space without the high costs of a normal satellite. Emphasis during the CubeSat design process is placed on use of commercialoff- the-shelf (COTS) components and reuse of previously-designed units.This report describes the interfacing of a scientific magnetometer, the Small Magnetometer in Low-Mass Experiment (SMILE) to such a CubeSat mission, the Space Weather using Ion spectrometers and Magnetometers (SWIM). Design of a complete platform for use in multiple such missions is presented here.Modularity is one of the key aspects followed in the course of the work. A new board containing the analog pick-up and compensation circuitry for SMILE has been designed to fit inside a CubeSat frame.

A strong brand can help a company to be easier to recognize and be remembered by their customers. Part of branding is to create a visual appearance which is called a graphic profile and contains information on for instance a logo, colours or typography.The objective of this thesis was to create a graphic profile for Stjørdal Tannhelsesenter that could serve as a base for a brand work in the future. It was important to analyze how the clinic wants to be perceived and how it is perceived today. The methods used to carry out this study were questionnaires, researches and a focus group.The work resulted in the generation of a graphic profile that included a new logo, colours, decorative elements, fonts, templates for stationery, business card / badge, imagery, and examples of some publications.According to the test which was made to examine the results of the project showed that I was successful and that the new design meets all the requests from the previous questionnaires..

It has since long been noticed that savior figures from different religions have reminded of each other, and there are different theories trying to explain why. This study examines religions operating in the same culture, and in this case, judaism and zoroastrianism, and their influence on each other. In particular, focus is on zoroastrianism's image of the savior figure Mithra, and how this representation may have influenced the description of the Messiah in the Talmud. How are the two figures represented in the scriptures and what similarities can be identified?By a thorough content analysis the studie examines the Avesta of zoroastrianism and the Talmud from judaism.

Although Dan Andersson (1888-1920) is considered perhaps the most important of the early Swedish workingclassauthors, there has not been much research on his work. Through a perspective based on critical whitenessstudies, intersectionality and existential phenomenology, this thesis performs a close reading of Andersson?sKolarhistorier (1914) and Chi-mo-ka-ma (1920) in order to map the discursive formations of whiteness andblackness in the texts, as well as to expose how these formations interrelate with that of humanhood.Since an underprivileged situation of oppression and poverty is the point from which the fictional worldunfolds in both Kolarhistorier and Chi-mo-ka-ma, whiteness is not an existential style within close reach for thecharacters. In Kolarhistorier the charcoal-burners claim themselves as ?weary of whiteness? and accordingly thetext establishes what the thesis reads as a realm of blackness where the black, male body becomes a locus ofpleasure instead of despair.

Multipel skleros, MS, är en neurologisk autoimmun sjukdom som drabbar centrala nervsystemet. Trötthet/fatigue upplevs av många som ett av de svåraste symptomen som inverkar starkt på det vardagliga livet. MS-relaterad fatigue/trötthet ger en känsla av utmattning och brist på energi som kan vara överväldigande. Tröttheten är orimlig i förhållande till de aktiviteter som utförs. Syftet med uppsatsen var att beskriva hur det är att leva med MS-relaterad fatigue/trötthet.

The aim of this thesis was to examine what expressions for objectivity there were to identify/find in newspaper journalism?s report about the FRA-law during the period 2008-06- 13 to 2009-10-14.We choose to analyze ten articles from the morning paper Dagens Nyheter and Svenska Dagbladet, five from each one. The method we used was a qualitative text analysis. We then designed an own model for the objectivity ideal from without the old theories that were available and also came with own ideas. Then we used that model as starting-point and designed key points to identify objectivity in the articles.Our thesis showed that the articles often fail when it comes to two key points.

This paper is partially a literature study of human error and interruptions and partially an investigation of pilots and Air Traffic Control. The aim of the investigation was to find out where interruptions occur and how to reduce or eliminate them. The objective of this paper was to investigate what type of interruptions pilots and ATC deals with and during which phases they occur. The paper has revealed that private pilots causes more interruptions for ATC personnel than commercial pilots. The cause for this is probably the less experienced private pilot and the fact that Swedish is used before English by private pilots in communication with ATC.

The objective of this work was to evaluate and implement a number of energy saving functions for a specific embedded system. The functions were then grouped into a number of energy levels with known properties in terms of functionality, energy consumption, and transition time between the levels.The embedded system consisted of an AT91 ARM9 processor, GSM/GPRS modem, display, Ethernet and other peripheral units. Some energy saving methods that were considered were suspend to RAM, suspend to disk, frequency scaling, and methods for saving energy in the modem, Ethernet, USB and display backlight. The functions were grouped into levels and an interface was specified for controlling the energy level.It proved possible to get known properties within the defined energy levels, even though the paritioning of functions into these levels proved to be sub-optimal in a typical application usage scenario because it was designed for mainly energy consumption, not usage.The final result is a number of energy saving functions grouped into levels, which are controllable via an application interface. Each of the levels have a known energy consumption in both loaded and un-loaded mode..

The increasing significance of social economy as a concept is linked to general global processes such as the crisis of the welfare state, neoliberal globalization, anti-bureaucracy tendencies and decentralization, but also to a growing political interest in human rights and social development. In Sweden the idea of the social economy generates wide support within civil society as well as within the government and across party political boundaries. Furthermore, what is problematic in this context is the fact that the discussions on the subject tend to be relatively uncritical and often it seems as if though the expansion itself is the main objective. The emphasis on cooperation and the third sector in terms of welfare production implies a set of risks in relation to state responsibility, democracy and the autonomy of civil society. This paper aims to explore those risks and how they can be dealt with within the Swedish context..

Sustainability issues have become increasingly high-profile and important in recent decades. In addition, quality issues have come to play a central role in corporate marketing, strategy and management. The word quality can be defined differently in different contexts. This paper focuses on the concept of quality, based on the Total Quality Management perspective, which in Swedish has come to be known as Offensiv kvalitetsutveckling. Offensiv kvalitetsutveckling has been described as a theoretical framework in which an organization continually strives to meet and preferably exceed customer needs and expectations at the lowest cost through continuous improvement, and in which all members of the organization are committed and focused on the organisation's processes. The purpose of this study was twofold. First, to clarify the applicability of the theoretical model Offensiv kvalitetsutveckling as a theoretical explanatory model. Second, to explore how Max Hamburgerrestauranger AB performs according to the values in Offensiv kvalitetsutveckling. A multiple case study was conducted in order to explore these topics. The results showed that Max Hamburgerrestauranger AB is working in a dedicated and value-driven manner, aligned with the values ??that form the basis for Offensiv kvalitetsutveckling. The results also showed that the model for Offensiv kvalitetsutveckling could serve well as a theoretical explanatory model, but that the model would benefit from being developed, enriched or integrated with other models.

Background: Goodwill has been a hot and debated topic for a longer period of time. Researchers have debated how goodwill should be accounted for and have not come to a solution. In 2005 IFRS standards came which meant that goodwill no longer will be amortized according to plan, but to be put through a yearly impairment test.Problem: A number of disclosure requirements in the financial reports have been made in an effort to avoid companies to account for goodwill differently. Apparently there still is a problem of how companies account for goodwill and there are several studies in the subject. But no one has studied how it is between two different industries, which make this study interesting to execute.Purpose/questions: This study have the purpose to investigate how the industries day to day wares and health care regards the disclosure requirements for goodwill by the impairment tests.

The controversial phenomenon of ?seeker-oriented? megachurches are currently transforming the American religious landscape. These churches, some housing up to 30,000 worshippers every week, are targeting religious seekers as their primary objective. Their success in attracting and converting those who usually wouldn?t even think of attending church can in large parts be explained by changes in liturgy, the removal of visible theological discussion and use of shopping mall styled buildings, designed to make the religious seeker feel like home.
