Extra! Extra! En studie i urval och nyhetsvärdering av push-notiser

This case study aims to find out whether the promotion of Swedish news through push technology, and the selection process behind it, obeys the traditional criteria of news values.A months-worth of push notifications, sent out by the mobile phone applications of newspapers Dagens Nyheter and Expressen, were analysed through the application of a number of taxonomies meant to determine their newsworthiness.These taxonomies were, however, based on 20th century media, and do not necessarily adapt well to analysis of digital news publication forms. The purpose of this study is therefore to find out which criteria are still relevant to the news selection behind a digitalformat such as push notifications; and which have become obsolete.The basis of this study is the criteria of news values originally designed by Galtung and Ruge in 1965 and revised by Harcup and O?Neill in 2001; as well as the model of assessing front page news proposed by Hvitfelt. The content analysis was conducted in a manner as similar to that of Harcup and O?Neill?s own study as possible, so as to constitute a re-revisal ?revamped for the digital age.Our results show that the criterion of ?frequency? ? that is the conformance between the time-span of an event and the publication frequency of a medium ? has acquired an ambiguous importance.

Hjärtfrekvens och hjärtfrekvensvariabilitet som fysiologiskt mått på mental stress hos hästar

SAMMANFATTNING Denna litteraturstudie syftar till att utvärdera hjärtfrekvens och hjärtfrekvensvariabilitet som fysiologiska mått på mental stress hos häst. För att utvärdera detta har olika artiklar studerats. Artiklarna redovisar studier där hästar utsätts för framför allt mentala stressmoment. Under stressmomenten har antingen hjärtfrekvens (HR) eller hjärtfrekvens och hjärtfrekvensvariabilitet (HRV) registrerats. Hjärtfrekvensvariabiliteten kan omvandlas till ett antal parametrar, bland annat lågfrekvensband (LF) och högfrekvensband (HF).

"Ettan" som kom först : En kvantitativ innehållsanalys av hur en studenttidnings förstasida förändrats genom tiderna

The aim was to explore how the first page of a student newspaper has been changed over time since it was founded in the 1960´s.This thesis explores how the front page of the student newspaper Lösnummer has been changed since it was founded in 1966. It concerns the location and frequency of elements and it is based on theories of layout, the first page and visual communicationIn addition, the thesis develops a new kind of method for determining the location of elements on the type area. The method is based on the hexadecimal number system. It is formed as a grid which is placed on the first page to determine the location of the elements.It concludes that the frequency of elements had its peak during the 1970´s and has ever since decreased gradually. Image placement has gone from being scattered all over the front page to be centered and increase in size. .

Bulleremissioner från vertikalaxlade vindkraftverk

Wind power in Sweden is expanding in response to the government's decision that 49% of Sweden's power should originate from renewable energy sources by the year 2020. Problems with noise and sound emissions related to wind turbines are a constant argument against the wind power expansion and this paper means to examine if vertical axis wind turbines might be a viable alternative to the conventional horizontal design for noise sensitive areas. In order to determine factors like difference in frequency, noise propagation and noise emission level, measurements of both horizontal and vertical axis wind turbines have been completed and the data analyzed with MATLAB. It is shown that there is a difference in how the noise from the two types of turbines propagates due to avariation in the frequency spectra of the emitted sound. It is also shown that vertical axis wind turbines generate a lower sound emission with less intensity inthe lower frequencies..

Sjukdomsfrekvens och utslagningsorsaker hos kor med 12 respektive 15 månaders kalvningsintervall

The incidence of many of the most common diseases in dairy cattle has been proven to be highest during the time closest to calving. It is possible that the current breeding strategy with 12 month calving intervals increases the risk for disease in dairy cattle, which is problematic concerning both animal welfare and for economic reasons. The economic incentives behind a calving interval of 12 to 13 months have mainly been based on milk- and feed- costs and no costs due to diseases or fertility disturbances have been included.The aim of this study was to see if a lengthening of the calving interval would result in lower disease frequency. The hypothesis is that cows with a planned calving interval of 15 months have a lower disease incidence than cows with a calving interval of 12 months due to less number of calvings. Therefore the difference in disease frequency should be larger when compared over a long period of time, such as over lifetime, since cows with a longer calving interval experience fewer calvings.The study was performed between August 17th, 1994, and January 24th, 2007.

Är Grönt Skönt?: En studie om hur effekten av grön marknadsföring påverkas av förekomsten av miljöargument inom produktkategorin

Al Gore may have helped put global warming on the agenda. However, it is not a new subject. Neither is so called green marketing a new phenomenon within branding and communication. As more and more companies establish environmental strategies there exist beliefs that the environmental focus is becoming a triviality, which is the reason for this study. Implementation of words such as ?environmentally friendly?, ?green? and ?global warming? is becoming more and more widespread and frequently used within marketing communication.

Internetbaserade insamling och behandling av data

AbstractAim of this project was to analyse signals and try to localize the position of source of sound. It is donewith three microphones which have 90 degrees angle to each other. Each microphone detects one partof the sound wave. The microphones are connected toan ADC which turns signals from analogue todigital shape. After that the three signals are transformed to a computer.

Aktiekursförändringar och sökfrekvens på internet

The purpose of this Bachelor thesis is to analyze if there is a correlation between stock prices and the amount of searches of the companies names on Google. The theories used in the study were Capital Asset Pricing Model (CAPM) and Efficient Market Hypothesis (EMH). Regressions analysis is used as the statistical method to see if there is a significant correlation between the stock prices and the amout of searches of the company name on Google. The data used were the rate of return of three companies (ABB, Oriflame and Sandvik) on the Nasdaq OMX Nordic stock market, the rate of return of the Nasdaq OMX Nordic stock market index (OMX Stockholm_PI) and the Google search frequency from Google Trends on each company. The result showed no significance and the conclusion of the thesis is that there is no significant correlation between the three studied companies and their search frequency on the search engine Google..

Mätsystem för effektförluster i en högfrekvenstransformator

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

Förekomst av törskate (Cronartium flaccidum, Peridermium pini) på tall (Pinus sylvestris) i relation till markfuktighet och fältskikt : en studie om 2000-talets törskateepidemi i norra Sverige

Resin-top disease is a rust fungi that occurs both as a host alternating form, Cronartium flaccidum G. Winter., and as a non-host alternating form, Peridermium pini Pers. The host alternating form can use a variety of hosts but the most commonly used species in the boreal forest is Melampyrum sylvaticum. In Scandinavia the Resin-top disease infect Scots pine, Pinus sylvestris L. The fungus infects the needles through the stomata and then grows through the branch to the stem where it strangulates the vessels transporting water and nutrition to the treetop, which kills the top.

Kontorsanställdas psykiska välmående i relation till deras fysiska aktivitetsnivå

Background: There have been doping usage as far back as as ancient Greece and around the early 1900s started the doping we have today. In 2008 it was 22,000 men aged 15-54 years old who had any kind of experience with doping in Sweden. The problem of doping use are all over the world and to overcome this problem, we need to work across borders.Objectives: The purpose of this study is to investigate whether there is any connection between the use of supplements and attitude to doping. The study is based on the questions: is there any connection between the use of supplements and positive attitude to doping? is there any connection between the use of supplements/doping substances and high training frequency? and is there different use of supplement/doping substances between girls and boys?Method: A survey in form of a cross-sectional study and a waiting room survey was conducted with 63 respondents of whom 57,1% were women.

Hur väljer man lämpliga SNP för produktion av SNP-chip?

The objective was to examine the frequency of unwanted behaviors in the Swedish feline population and what factors in the environment, inheritance and past life that have an influence on the frequency. SLU?s web poll generator was used to create a web poll which insinuated that it was a poll with objective to make an inventory of the Swedish feline population. I wanted to avoid that only owners to cats with unwanted behaviors answered the poll. The web link to the poll was sent to SLUs students and posted on Internet forums for people interested in cats.

?Bollen susade in i bortre gaveln? - En studie i rörelsekonstruktioner och produktivitet

This paper investigates the grammatical construction intransitive motionconstruction with GOAL as it is used in Swedish (Swe. intransitivrörelsekonstruktion med MÅL).I examine in which ways the construction is productive, i.e. thepossibility to use the construction with new verbs as well as withordinary motion verbs with new functions. The notion of productivity isbased on the construction?s type frequency and semantic openness(Goldberg 1995, 2006; Barðdal 2008; Bybee 2010).

Utveckling av Breakoutbox för Fuel Flow Transmitter

Development and construction of an electronic Breakout box is the main work for this thesis. The box is a part of a test system for the component Fuel Flow Transmitter and should convert signals to be suitable for a frequency counter. A previously constructed Breakoutbox for this purpose is being old and needed to be recreated. So SAAB Aerotech, Aircraft services, the company for the thesis work wanted to construct a new, more sustainable Breakoutbox adapted to a more modern technology. The signals to the box comes from the transmitter and should be converted to suitable signals for a frequency counter so it can show pulse and time difference between the signals.

En studie av sex ISA-system

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.
