Insamlingsorganisationer - vad förklarar omfattningen av redovisningsprinciper?
The natural disasters of recent time have caused the people of Sweden to donate very large amounts of money to different fundraising organizations. With this in mind, we found it interesting to examine the extent of disclosure in the annual reports of the Swedish fundraising organizations. Thus, the purpose of this study is to identify which factors that influences the extent of disclosure of accounting principles in the annual reports of Swedish fundraising organizations. To fulfill this purpose we conducted a content analysis of 149 annual reports from Swedish fundraising organizations. To help us explain the levels of disclosure we applied stakeholder theory, institutional theory and legitimacy theory.
En förskola I Tantolunden : Från frisk luft till fantasigenererande miljö
Enligt en rapport från Socialstyrelsen 2013 framgår det att få förskolor arbetar systematiskt med att förebygga en miljö där allergi kan uppstå. Ca 80 % av landets förskolor hade fuktskador eller en konstruktion som innbar en förhöjd risk för fuktskador. Endast 40 % av skololorna hade ett ventilationssystem som godkänts genom en så kallad godkänd ventilationskontroll.Barn är inkännande. De absorberar och uttrycker det som vuxna i deras omgivning medvetet eller omedvetet projicerar. Om de känner sig trygga och glada är det en reaktion av de vuxna som omger dem.
Design of a Direct-conversion Radio Receiver Front-end in CMOS Technology
In this Master's thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a result, no front-end image reject filter is required and the channel selection requires only a low-pass filter, which makes it easy to integrate directly on chip. However, the DCR also suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch.
En känsla av samhörighet : En utvärdering av Umeå universitetsbiblioteks övergång till RFID ur ett personalperspektiv
Denna utvärdering av Umeå universitetsbiblioteks (UB) övergång till RFID-teknik (radio frequency identification) tar upp hur personalen har upplevt konverteringstiden och övergången. Syftet var att undersöka den involverade personalens åsikter och attityder kring omställningen och de eventuella konsekvenser och effekter som RFID-övergången fört med sig.Undersökningen genomfördes med korta uppsökande intervjuer vars frågor utformats i samråd med Umeå universitetsbiblioteks projektledare för RFID-konvertering. Frågorna resulterade i kvantitativa svar men respondenterna gavs möjlighet att utveckla sina svar med egna reflektioner. Av de totalt 17 respondenterna var nio män och åtta kvinnor i åldrarna 32-64 år. Resultaten visar på en till stora delar nöjd respondentgrupp, majoriteten tycker att övergången till RFID har fungerat bra, de flesta känner sig opåverkade i sin yrkesroll efter införandet och endast ett fåtal har lämnat konverteringstiden med några bestående men som drabbat deras arbete eller de själva. Bland respondenterna finns det en generellt positiv inställning till RFID-teknikens framtid på arbetsplatsen och ett flertal hoppas på en vidareutveckling och utbyggnad av tekniken..
Design av mikrovågsövergångar
In this Master thesis, microwave connections between circuit boards are constructed. The primary frequency band is the X-band (8-12 GHz). The purpose of the connections is to enable a more simple and cheaper way of mounting the circuit boards inside a container. The connections have been designed and evaluated, using different computer programs. A few prototypes have been built and measured.
Vägen till beröring i det palliativa skedet
In the palliative care there are many close encounters between the care-taker and the care-giver. To be touched is foundational to every human being and the care-giver shows his presence to the care-taker, when he touch the care-taker. Touch is an important tool for the care-giver in the care for the care-taker. It becomes a natural way of communicating. The aim of this literature study was to describe which factors that are important, for the care-taker in the palliative care, to receive touch in the purpose of feeling well-being.
Lärare och digitala verktyg i matematikundervisningen : En kvantitativ studie om lärares inställning och kompetens kring användningen av digitala verktyg i årskurserna F-3
The purpose of this study is to examine in what extent primary school teachers, teaching children in the age of 6 to 9, choose to use digital tools in their teaching of mathematics. I also want to examine what these teachers think, in terms of advantages and disadvantages, about using digital tools on their mathematics lessons. Finally I want to examine what skills they possess about digital tools.I am using a quantitative method to collect my data. The quantitative survey consisted of a questionnaire survey of ten questions that 38 primary school teachers have answered.The results of my study show that the teachers to some extent use digital tools when they teach mathematics and that the availability of various digital tools are generally good. But it turns out that the availability of tools is not a guarantee that they are used in teaching of mathematics.
Debatten om bibliotekarieutbildningen ? inför förändringarna av utbildningen år 1972 respektive år 1993 ? sådan den återspeglas i bibliotekstidskrifter
The purpose of this thesis is to examine the debate in library journals and in official reports on the subject of library education in Sweden. We focus on two periods: the period just before the year 1972 ? when the library education was transformed into being occupationally-oriented and the period just before the year 1993, when the library education was transformed into being ?academised?. This Master?s thesis shows that the debate and the arguments among initiated people in the library world have had some impact on how the library education was transformed later on.
Vad styr förekomsten av sälg och asp? : en studie av olika beståndstyper inom Hamra kronopark, Dalarna
Aspen (Populus tremula L.) and goat willow (Salix caprea L.) are two important tree species in the aspect of nature conservation. Due to the elimination of forest fires, a former negative attitude towards deciduous trees in forestry and a strong herbivore pressure, these tree species have been negatively affected during the last fifty years. The aim of this study was to investigate whether the occurrence of aspen and goat willow could be related to either human impact or to site properties, such as ground moisture and vegetation type. A side study included an inventory of a number of cyanobacterial tree lichens on aspen and goat willow in order to try to relate the occurrence of these lichens species to stand history and stand properties.
The study was performed in Hamra State Forest in northern Dalarna. Nature reserves were compared with stands in managed areas.
Kärnkraft : Ett arbete för drifttekniker?
The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.
Fördelning av frambensskador på ytliga böjsenan hos galopphästar :
Superficial digital flexor tendon injuries are common causes of premature retirement or pre-longed convalescence periods for race horses. The curve gradient at Täby Galopp race track is very small and most races as well as high speed training are done on the left rein.
It is believed that the horses left foreleg is under considerably more strain then the right foreleg when being ridden on the left rein during gallop at high speed. During gallop on the left rein the horse puts its entire weight on the left foreleg when regaining ground contact.
The purpose of this study has been to find out, through analyzing the statistics concerning the horses that visited the ATG clinic at Täby during a period between January 2003 and September 2006, whether there is a higher frequency of superficial digital flexor tendon injuries on the left leg rather than the right and if so, can this support the theory that the design of the race track in combination with continuous left rein races can be a contributing cause of these injuries.
The result of the study shows that 57% of the tendon injuries occurred on the left front leg and 38% on the right front leg. The difference is not large enough to support the above theory of the underlying cause of these injuries..
Energikartläggning och driftoptimering genom behovsstyrning i befintlig fastighet
Energy supply in Sweden year 2011 amounted to 577 TWh. The final energy consumption for industrial, residential and service was 379 TWh. Sweden has energy policy goals to reduce energy use in buildings. One of these goals is to reduce the energy use by 20 % in 2020 compared to the year 1995. An important step to achieve this goal is to target energy efficiency measures in existing buildings.
LNG träningsmanual för M/T Bit Viking
Denna uppsats är gjord på uppdrag av Tarbit Shipping som år 2011 konverterade sin tankbåt M/T Bit Viking från konventionell drift på tjockolja till LNG (Liquefied Natural Gas).Uppdraget som gavs var att upprätta en tränings manual till fartyget då det är ett krav från IMO (International Maritime Organization). Manualen skrevs i 3 st huvuddelar Kategori A, B och C. Kategori A är till för att manskap ombord ska få en kännedom om gasen och säkerhet runt den, Kategori B är skriven till däcksbefäl där det krävs en större kännedom om gasen och Kategori C är till för maskinbefäl. Manualen finns nu ombord på fartyget och på rederi kontoret för utbildning av nypåmönstrad personal och fortlöpande utbildning av ordinarie personal. Manualen är ett resultat på tolkning av IMO´s IGF kod (ANNEX11.
Kjoltyg och magiska skönhetsunder: en jämförande diskursanalys av hur journalisterna på Slitz och Veckorevyn representerar kvinnan
The purpose of this study is to compare how the male journalists of the Slitz magazine and the female journalists of Veckorevyn represent the female sex. Slitz is dominated by sensual, sexy pictures of women. The texts describe the women on the basis of the journalists opinions. The women themselves do not get the same opportunities as the journalists to tell the readers who they are. Slitz magazine objectify women, they seem to be aware of it and do not hide their purpose.
