Den skeva bilden : En studie i hur brottsrapporteringen i Efterlyst ser ut jämfört med brottsstatistiken, samt hur programmets tittare upplever att de påverkas
The purpose of this thesis was to determine the tv-show Efterlyst?s (Wanted)effects on viewers when it comes to how crime, criminals and victims are portrayed in the show. In order to achieve the purpose of our the study, both quantitative and qualitative approaches were used We compared the image Efterlyst gives of crime, criminals and victims to statistical information from The Swedish National Council for Crime Prevention and The Central Bureau of Statistiscs. By using focus-groups we also studied how Efterlyst portrays, in the season of 2009, and how it may have affected its viewers. Our conclusion was that there are important differences between how Efterlyst portrays crime and the image of crime the statistics gives.
Patent och företags storlek - finns det en tröskel till inträde?
Several studies have investigated the relationship between different measures of innovative activity, such as patent statistics and R&D expenditures and some have looked deeper into the differences between large and small firms regarding number of patents issued per employee or per R&D dollar. In this paper, the objective is to find out if there are any indications of a barrier to entry (due to economical factors, lack of knowledge etc) for small firms to get into the field of patent handling. The approach is to first set up a hypothesis based on some simple assumptions about how firms would make decisions about whether to apply for a patent or not and thereafter use econometric methods in an empirical investigation. The data used for this study are figures on number of employees, number of patents granted and R&D expenditures for the Swedish firms in the pulp and paper industry. The main conclusion is that, based on the analysis of the data from this rather limited group of firms, no such barrier can be seen..
Preventiva åtgärder mot övervikt hos barn och ungdomar. Litteraturstudie.
Statistics regarding children, who are overweight, shows alarming results in many parts of the world. Overweight may cause serious consequences, as for instance heart- and vascular diseases. Research is pointing out that hereditary, social, behavioural and cultural facts may promote developing overweight and it is of great importance to find out how to prevent overweight and obesity in children and adolescents. The purpose of the literature study was to compile primary and secondary preventions against overweight/obesity in children and adolescents. The result showed that prevention through education, recommendations, healthy eating and exercise may be usable in the work to prevent overweight among children and adolescents.
Förnuftets fostran och framsteg : Relationen mellan begreppen frihet och utbildning hos Condorcet.
The majority of the interest for Marie-Jean-Antoine-Nicolas de Caritat, Marquis de Condorcet (1743-1794), has been focused on his work in mathematics and political science, especially on his famous method on voting tally. With a background in the French enlightenment, on the brink of the revolution, this essay focuses on his political and philosophical ideas, specially his thoughts on the role of education in humanity?s struggle toward greater freedom. Is it possible to identify a connection between the concepts of education and freedom in his writings? This question is largely unanswered, even though it is fundamental for the understanding of the underlying reasoning of Condorcet.
Laborativ matematikundervisning i årskurs 5 : En jämförelse mellan lärare och elevers uppfattning angående användningen av laborativt material
Under de senaste åren har intresset för användningen av laborativt material ökat markant. Syftet med denna studie är att ta fram och göra en jämförelse mellan lärare och elevers uppfattningar och åsikter angående användningen av laborativt material i matematikundervisningen. Studien har genomförts på fyra lärare i Örebro samt deras klasser i årskurs 5. Resultatet visar att laborativt material underlättar lärandet, gör matematiken roligare och mer intressant, för många enligt både lärare och elever. Lärarnas och elevernas uppfattning om hur ofta laborativt material plockas fram och då finns tillgängligt skiljer sig åt.
Utveckling av priset på bostäder i Kina
Under de senaste 30 åren har Kinas ekonomi utvecklats snabbt, vilket hänger väl ihop med landets fastighetsutveckling. Sedan den marknadsinriktade bostadsreformen 1998 har Kinas bostadsmarknad haft en snabb tillväxt med en kraftig prisökning under de senaste fem, sex åren. Denna uppsats har syftet att undersöka de kinesiska bostadsprisernas utveckling och utforska de faktorer som drivit bostädernas prisutveckling. Med insamlade årliga data från Kinas National Bureau of Statistics för perioden 1995-2010 genomfördes grafiska analyser och ekonometriska analyser. Studiens grafiska resultat visar att bostadspriset har en stabil utveckling under perioden 1995-2004.
Centrala Begrepp som Länken Mellan Ämnen : En undersökning av de centrala geografiska begreppens interdisciplinaritet
Language is an important indicator of the interdisciplinarity of a certain subject. Therefore this study evaluates the use of central geographical words and concepts, by teachers and students, in seven communal, non-optional subjects in a Swedish upper secondary school. This study provides results after observations of seven subjects on seven occasions, at one upper secondary school. This study shows that by a method of observation, central geographical concepts were used by teachers and students at various extents. Furthermore, the observations provide results of the concept use by over 100 students and 12 teachers.
Vad förmedlar en förskolas barnböcker ur ett genusperspektiv? : En kvantitativ studie av 136 barnböcker
The purpose of this study is to investigate how male and female is produced in the literary children?s literature that is found in a Municipal preschool. My issues are the following:Which sex dominates as a main character in the preschools literary books?What type of properties is attributed to the characters?What type of clothes is portrayed on the books characters?I performed a quantitative study of 136 children?s books. I used Maria Nikolajevas perceptions of stereotypical male and female properties to analyze my empirical data.
Idiopatisk epilepsi : en fallstudie
Epilepsy is a common neurological condition in dogs, being a common reason for
death in the statistics from the insurance company Agria in Sweden. Among the
different types of epilepsy, idiopathic epilepsy (IE) is the most common and is
characterized by the fact that a veterinary examination does not reveal a cause for
the seizures. This study has been conducted through studies of medical records
and interviews with dog owners. From a total number of 103 dogs that were
neurologically examined for seizures, 42 dogs met the inclusion criteria, being
classified as having idiopathic epilepsy. When the study was performed, 28 dogs
had died, while 14 were still alive.
Lanczos potentialer i kosmologiska rumtider
We derive the equation linking the Weyl tensor with its Lanczos potential, called the Weyl-Lanczos equation, in 1+3 covariant formalism for perfect fluid Bianchi type I spacetime and find an explicit expression for a Lanczos potential of the Weyl tensor in these spacetimes. To achieve this, we first need to derive the covariant decomposition of the Lanczos potential in this formalism. We also study an example by Novello and Velloso and derive their Lanczos potential in shear-free, irrotational perfect fluid spacetimes from a particular ansatz in 1+3 covariant formalism. The existence of the Lanczos potential is in some ways analogous to the vector potential in electromagnetic theory. Therefore, we also derive the electromagnetic potential equation in 1+3 covariant formalism for a general spacetime.
Barns intresse för matematik : En studie i två klasser i årskurs sex
När vi har varit ute i olika skolor har vi sett tydliga spår hos elever att deras intresse för matematik minskar ju högre upp i åldrarna eleverna kommer. Vi har även observerat många olika typer av lärare och undervisningsstilar. Syftet med arbetet är därför att titta närmare på hur intresset ser ut i två klasser i årskurs sex på två olika skolor samt titta på vilka faktorer som påverkar intresset hos eleverna. För att ta reda på detta har vi utfört enkätundersökningar i de olika klasserna. Utifrån svaren från enkäterna valde vi ut fyra elever i varje klass för intervjuer, hälften som enligt enkäterna tyckte om matematikämnet och hälften som inte tyckte om det.
Fritidshemmet som matematisk lärandemiljö : - möjligheter och hinder
Syftet med min studie har varit att undersöka om fritidshemmet kan utgöra en matematisk lärandemiljö. Jag har studerat vilka aktiviteter som kan eller skulle kunna bidra till att barn utvecklar grundläggande matematiska kunskaper. Dessutom har jag försökt identifiera hinder för fritidshemmet som matematisk lärandemiljö. För att undersöka detta har jag använt mig av deltagande observation som metod samt intervjuer. Datamaterialet har samlats in på två fritidshem i två olika kommuner.
Skogsmaskiners bränsleförbrukning :
This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The aim of the work was to compare fuel consumption during work in practical field conditions with a standardized method developed by Skogforsk (The Forestry Research Institute of Sweden), (Brunberg, 2005) for harvesters and forwarders from different manufacturers and of different sizes in order to promote the development of more fuel efficient machines.
Two studies were carried out.
- Statistics of fuel consumption were collected.
- An inquiry was sent out in order to get more detailed information of different aspects influencing the fuel consumption.
The studied machines were divided into two classes, large machines (> 150 kW), and average size machines (100 ? 150 kW), and of the manufacturer Timberjack and Valmet.
Our results shows a 15 % lower fuel consumption for average size harvesters and an 8 % higher fuel consumption for large harvesters compared with Skogforsks model.
Formativ bedömning och individanpassad undervisning i matematik. En inblick i hur dessa metoder ter sig i grundskolan.
Syftet med arbetet är att undersöka hur lärare resonerar kring hur de arbetar med formativ bedömning och individanpassad undervisning i matematikundervisningen i grundskolan. Vi har därför undersökt detta område närmare genom en empirisk enkätstudie. Vårt urval har bestått av respondenter som dagligen möter denna problematik och som har erfarenheter inom området d.v.s. grundskollärare.
Hälften av respondenterna hävdade att de individanpassade matematikundervisningen i stor utsträckning, resterande i måttlig eller liten utsträckning. Gällande frågan om formativ bedömning svarade omkring hälften av respondenterna att implementeringen av formativ bedömning sker i stor utsträckning och resterande i liten eller måttlig utsträckning.
Utfackningsvägg i fältfabrik : en studie av arbetsmiljö och enhetstider
Construction companies are frequently criticized for high prices and long construction time. At the same time, statistics shows that construction workers are on the sick-list for occupational injuries or casualties more than other groups at the labour market.Skanska built a block of flats with tenant-ownerships in Gävle. The construction consists of concrete walls with in-fill walls in the front. The purpose with this degree project is to perform a risk analysis in work environment with focus on repetitive strain injuries and control the time report for in-fill walls manufactured in a field factory. The result of this project will help to make more realistic cost predictions in the future.This degree project has been performed in cooperation with the construction company Skanska.
