Smartphones som undersökningsinstrument
As the number of people owning a smartphone rapidly increases so too does the opportunity for various researchers to exploit this technology. The possibility to recruit people to participate in research studies improves and with it the chance to get more diversified target groups in terms of age, socio-economic status, geographical location, etc.In this essay, I argue that the opportunities smartphones offer in terms of collecting research material is vastly underestimated in several areas, bearing in mind the advantages they present. In order to support my argument, I shall present a case study carried out in the research area of happiness ? an area where the use of smartphones has provided significant opportunities for research.In order to gather the advantages and disadvantages of this method of study from the participants? perspective, I have followed a happiness research study which is a collaboration between Umeå University and The University of Stockholm. I have interviewed the participants of this study in order to assess the advantages and opportunities that smartphones offer in research programs.Overall, the participants? opinion of this research method was generally positive and it was considered to be quite easy to participate in the study and respond to the questions asked.
Variation in piglet mortality between and within satellites in a sow pool
The piglet mortality rates have become a major issue in today?s pig production. While other production traits such as number of born piglets or produced piglets per sow have been improved, the mortality rate has escalated. High mortality rates before weaning does not only affect the economy but must also be looked at as both an animal welfare problem and an ethical issue. The background to this problem has been addressed many times, and its salvation has also been addressed by breeding.
Aktiv ventilstyrning
To achieve an optimal combustion, an even air/fuel ratio in the combustion chamber is required. An optimal combustion leads to reduced amount of emissions due to a more complete combustion, which is an important matter because of the sharpened environmental laws. This can be attained, among other things, by applying entirely variable cam times. To optimize the engines efficiency and its emissions at all workloads and speeds, an active valve control can be applied. This means that the intake and exhaust-valves can be opened and closed at any time, independent of the crankshaft position.
Vad ska man med dynamisk pedagogik till? : En studie av möjligheterna att använda den dynamiska pedagogiken i praktisk verksamhet
Syftet med studien är att ta reda på om dynamisk pedagogik går att använda i praktisk verksamhet. Studien har ett kvalitativt perspektiv och består av en litteraturstudie av Lipschütz (1971/ 2004), en intervjustudie med tre deltagare och en enkätstudie med 32 deltagare. Deltagarna har genomgått utbildning i dynamisk pedagogik och/eller är medlemmar i Korda ? föreningen för dynamisk pedagogik, en del använder dynamisk pedagogik i praktisk verksamhet och andra gör det inte. Resultatet diskuteras mot bakgrund av tankar och teorier kring den dynamiska pedagogikens framväxt,målsättning och metoder.Resultatet visar att dynamisk pedagogik går att använda, och används, i praktisk verksamhet i olikagrad, på olika sätt och i många olika slags verksamheter, främst i ledarskap och inom utbildning avolika slag, framförallt för personlighetsutveckling, grupputveckling och ledarskapsutveckling.
Omvärldsanalys i olika typer av organisationer. En jämförande studie av omvärldsanalysen i en kommun och ett företag.
This master thesis deals with the differences in the design of the environmental scanning between different kinds of organisations, as well as the demands and regulations etc. in the respective environments that influence the environmental scanning. The content of the environmental scanning and the organisation of the function are outside the scope of this study. Two organisations that do not have an organised function but are scanning their environment were chosen for the investigation. A model for conducting the environmental scanning developed by Frankelius is used to analyse the practice of environmental scanning.
Enbarnspolitik och saknade kvinnor : en fallstudie av rätten till liv i Indien
It is not unusual that women and children fall behind in development countries. It is not even unusual that these groups are exposed to all forms of discrimination due to the countries lack of capacity to erase poverty. We also know that women and children in a larger extent suffers from the shortage of proper health conditions. India is one of these countries. It is a country where women even before birth are exposed to discriminatory family planning.
Elefantens könsorgan, reproduktion och embryoutveckling
Hydropericardium or pericardial effusion (PE) is the accumulation of fluid in the pericardial sac and is often secondary to pericardial diseases or diseases related to the heart. It is unusual with clinically relevant pericardial diseases in cats but pericardial effusion is the most common one.
Since PE causes serious symptoms and may lead to death it is important with a quick diagnosis and treatment. PE can be acute and cause cardiac tamponade, which gives severe clinical signs. Cardiac tamponade needs to be treated immediately or else the cat will die from cardiogenic chock. More common is chronic PE where the fluid accumulates during a longer period of time and the pericardial sac stretches.
Att bryta tystnaden: kommunikation i matematikklassrummet
The purpose of this study is to investigate how teachers approach communication in their
mathematics instruction. The communication involves concepts such as teachers'
mathematical language, incorrect answers, and various interaction patterns. In line with this,
the study also examines how these types of communication may affect students in the
classroom. Furthermore, observations and interviews were conducted with five different
teachers in Sweden using an observation scheme and an interview guide. The results reveal
that four out of the five teachers use both child-directed and adult-directed language when
addressing students at different levels of mathematical understanding.
Förlagsredaktörers informationsbeteende. En studie av förlagsredaktörer som arbetar med facklitteratur.
The main purpose of this work was to examine the information behavior of nonfiction publishing Company editors. Three problem areas were presented and expressed in the following questions:- What is the information need of the editor in every day work?- Which sources of information do the editors use when they are looking for information and how do they make use of them?- Are there any factors that have an influence on the information behavior of the editors and in what way do the factors effect the information behavior of the editors in their everyday work? And finally, do the editors experience any factors as barriers to information behavior?Six editors, all with academical background, all employed in different publishing companies were interviewed. The result of this study have been analysed within a theoretical framework influenced by the work of Tom Wilson, Lars Höglund and Olle Persson and Block and Lagberg. The result shows that the editors had various regular needs of information in their every day work.
Den användarskapade elden Risker och möjligheter med kriskommunikation i sociala online-nätverk
Title The User Created Fire ? Risks and Opportunities with Crisis Communication in Social Network SitesAuthor Charbel SaderCourse Master Thesis in Media? and Communication Studies, Department of Journalism and Communication, University of GothenburgSemester Spring semester of 2013Tutor Nicklas HåkanssonNumberof pages 75Purpose To find a deeper understanding of the digital media?s role in Swedish society in relation to crisis communication.Method Qualitative approach using focus group interviewsMaterial Semi structured focus group interviews with a total of 18 participants in five groups. The focus group sessions were made during February, March and April 2012.Main results The main findings in this study are that users expect the communication flow in social network sites (SNS) during a crisis is to be a shortcut to information without a detour through organizations or traditional media. Although we find personal gratification, like interpersonal communication, quick information and sharing feelings and experience with others by using SNS during a crisis, users also tend to be hesitant about the credibility of the shared information. Alongside the user created content, we look to professional media experts and organizations as a guarantee for the veracity of the shared information.
Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood
Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. Wood modification with epoxidised linseed oil (ELO) and acetic acid as catalyst has proven a suitable method to impregnate and protect wood. However, the mixture presents a serious inconvenience because of the quick polymerization of the ingredients that limits its practical application. Therefore, this study was designed to evaluate an alternative method using a two-step process which bypassed the problem above.
Måltiden som symboliskt kapital - en etnologisk studie av mat, medelklass & identitetsskapande
This paper aims to investigate how human beings uses food to found an identity, with regards to how social class affects their choice of food and if trends play a part when it comes to cooking and purchasing food. The paper applies theorist Pierre Bourdieu's concepts such as habitus, capital and field.The main part of the material is composed of four interviews with seven informants; all of which is middle class. The paper also looks at how lifestyle, taste and attitudes to consumption are used when the informants build identity. The empirical part is split into three main subjects, where I first seek to find each informants food habits. What do they eat, and what do they not eat?It showed that a large part was due to their varied lifestyles, however generally speaking the day to day meals should be quick while meals during the weekends could take longer and also cost more.
Implementation of a Data Handling System for a Scientific Magnetometer on a CubeSat
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.
Ljudisolering - Teknisk felsökning och kvalitetssäkring av lätta bygg-system
By using industrialized building, pre-installed modules can be delivered to the construction site where they are easily mounted. This method has many advantages compared to on-site manufacturing, for example, the precision during the production process should be much higher than building each wall and floor on site. Furthermore, the quick erection procedure when using prefabricated elements and the possibility to use weather protection has the advantage of not being dependent on weather conditions, and many other factors.Masonite Beams AB is a Swedish company (a member of the Norwegian company, Byggma ASA) with a relatively new technology using light weight beams as bearing elements in the walls and a certain stiff board lamella slap which is mounted on the top of the floor structure creating an integrated stiff beam / board floor structure. The elements are flat which make it much easier to transport the elements from the factory to the building site where the building parts are easily mounted with special mounting stud.One of the main drawbacks of lightweight structure is the sound transmission. The main topic is low frequency annoyance, however the complex structural elements and their mutual sensitive connections other acoustical problems might appear.
