Mark röjd från sten : En studie av förklaringar och tolkningar kring röjningsröseområden
AbstractThis essay discusses different explanations and interpretations of what characterizes large areas containing clearance cairns (cairn fields). Results from the analyses show that there are different explanations about when and why cairn fields and clearance cairns occur. Explanations vary from introduction of the wooden ard in the early Bronze Age to the introduction of rational hay-making in the Roman Iron Age. There is, anyway, relative agreement considering why and when cairn fields were abandoned. The reason suggested is an increasing pasturage with the consequence of reducing soil to poverty during the period of the Great Migration or in the Viking Age.The most likely cultivation system in cairn fields is a system consisting of both intensive and extensive characteristics. The latter coincides with the probable mobility of settlements.
Inventering och riskanalys av skolskjutshållplatser : kvalitetsäkring med avseende på trafiksäkerhet
In Trollhättan municipality approximately 700 school bus stops are in service. To ensure high quality of the performance of school bus operations, with focus on traffic safety, it was decided to conduct a survey of bus stops including assessments of risks.This master thesis aims to identify the factors affecting road safety at bus stops and pedestrian connections, and to conduct an inventory and analysis of selected sites in Trollhättan municipality. The work also aims to show examples of how risk assessment should be performed in future studies. A risk analysis model provided by the Swedish Transport Administration is supplemented and used in a field study. The risk assessment is based on, inter alia, traffic flow, visibility distance, lighting, speed of traffic and the presence of bus shelter.
Objektiv rörelseanalys : ett stöd vid den visuella bedömningen av hälta hos hund?
Lame dogs are a common group of patients for the practicing veterinarian. In the
literature it is described how a clinical examination can be performed, based on
general clinical-, orthopedic- and neurological examination, and visual evaluation
of the dog when standing and during motion. For research, objective gait analysis
systems are also used to study clinically healthy and lame dogs during motion.
The aim of this degree project was to compare objective kinematic gait analysis
with a visual evaluation of dogs with different types of lameness. The project was
a pilot study to show if objective gait analysis could be used as a support for the
visual examination.
Ten lame dogs of different breeds and with different diagnoses were included in
the study. They were all patients at the University Animal hospital, Uppsala.
Scintigrafisk undersökning av esofagusmotilitet hos häst :
Scintigraphic examination of the esophagus has for some time been the method of choice for the study of motility dysfunction in humans. The method has not yet been described for horses hence the lack of reference values for passage time for a bolus through the esophagus in healthy subjects. The purposes of this study were to measure passage velocity and time for a bolus to pass through the esophagus in healthy subjects, as well as to evaluate the reproducibility of the method. Eight warm-blooded trotters were used in the study. The horses were sedated with a low dose of Acepromazine prior to onset of the study.
A risk analysis of moose close to roads
For many decades the increase in traffic volume, expansion of highways and infrastructure has lead to an increase of wildlife vehicle collisions which are unfortunately very common in many countries today. They cause great deal of material damage and even kill humans or wildlife. Measures in the form of warning signs, under- and overpasses and fencing have been implemented for a long time with the help of observation by hunters and collisions sites. However this study focuses on the moose?s perspective and the variables that, both spatially and temporally, could have an effect on why and when moose are close to certain types of roads.
Hur har utvecklingen av andelen pension?rer i befolkningen p?verkat Tysklands arbetskrafts storlek fr?n 2000 till 2022?
Germany has experienced low birth rates ever since the 1970s when they fell below the replacement levels of 2,1 children per woman. Since then, their birth rate has been around 1,5 children per woman, which has caused an overall aging population. The consequences of the declining birth rates is that the previous generations are becoming larger than the younger generations. This demographic shift raises concern about how its potential implications might affect different aspects of the country and its economy overall. The aim of this paper is to try to discern the dynamic between the share of the labor force in relation to total population, with the share of pensioners in relation to the total population.
Den ultimata träningsmetoden?
Crossfit is a recently developed form of training which is based on a number of functional resistance exercises performed at high intensity, often to the point of muscular failure. Crossfit has since its introduction 30 years ago, reached vast popularity all around the world, including Sweden. Its practitioners considers Crossfit to be an effective training method for achieving a functional and total trained physique thru improvements in VO2max, muscle strength, endurance, balance and speed. Few scientific studies has been published in the subject which is why this study sets out to examine the effect of Crossfit on VO2max (measured with Åstrands submaximal cyclingtest), maximal strength capacity in lower- and upper body muscles (measured with 1 RM tests in bench press and leg press), rapid strength capacity and strength endurance capacity in upper body muscles (measured with push-up test in 30 seconds) and explosive strength capacity in lower body muscles (measured with sergeant jump test). Five women with an average of 33(±5) years of age all new to Crossfit, performed these tests at two separate occasions with a training period of four weeks consisting of 12(±3,67) Crossfit sessions in between.The result showed a significant improvement in the maximal strength capacity of the leg extension muscles (p=0,025).
Läsförståelse av faktatexter i NO, med stöd av Leselos, en norsk arbetsmodell : En fallstudie av en intervention i årskurs 3
To read and understand are essential competences for everyone in our society; at the same time reading comprehension among Swedish pupils is on the decline. The Swedish school must therefore try to improve their instructions to increase the students' reading comprehension. The aim of the study was to describe how three reading comprehension strategies, if possible, could improve the reading comprehension for the students, including children with learning disabilities, when reading texts of natural science in a third-grade class. The three strategies that were introduced were: to activate prior knowledge, to structure information and to record contents. The questions of the study were: How are the three strategies introduced in the classroom? Can the children with learning disabilities see any benefits for their reading comprehension when working with the strategies? How do the children with learning disabilities experience working with the strategies? Can the teacher see any benefits when working with the strategies? Is it possible to see any differences among the students' results, before and after completed intervention? Method: The results have been collected through observations and qualitative interviews, which make this a qualitative study.
Price transmission dynamics of Chinese ADRs listed on the NYSE
Purpose: This study aims to examine the price transmission among ADRs (American Depositary Receipts) and their underlying shares, US market index and Hong Kong market index. We will attempt to capture how a shock in the home market is transmitted to the foreign (and vice versa). In addition we will attempt to assess the relative weight of each variable in the system generating unexpected variations of its own and other variables and at what speed the shocks are absorbed.Methodology: ADF unit root test, Johansen?s co-integration test, Granger causality test, VECM, impulse response, variance decomposition Empirical foundation: Five Chinese ADRs listed on the New York Stock Exchange. Each ADR represents a specific industry.
Friidrottsungdomars fysiska kapacitet över tid : En retrospektiv studie av intagningstesterna vid friidrottsgymnasiet i Växjö mellan åren 1982 ? 2009
Background: Today when leisure time is spent, spontaneous sports activities decrease, due to a more comfortable way of living and physical capacity among non active adolescents decreases. There for it´s interesting to see how the physical capacity level has changed over time among young people participating in organized leisure time sports.Studies around the world show that young people standing outside organized sport activities have tended to decrease their physical activity levels over the last few decades. Less leisure time is spent doing physical activity and sometimes gets put into context with increased time spent behind the computer or inactivity.Design: A retrospective study of the test results on physical capacity between 1982 and 2009 for students applying to Växjö track and field high school. A total of 635 students (15 years old) have done 11 physical tests during the years. Five of these tests, with enough participants (at least 100) and documentation over at least 10 years, were used in this study.Results: This study shows that young track and field athletes have maintained the same physical capacity from 1982 to 2009.
Nya regler i sjukförsäkringen - fler personer i utanförskap?
The purpose of this paper is to study the rules of the bill 2007/08: 136 "Areformed sick-leave process of increased return to work" as related to therehabilitation chain. In the interpretation of the material I have used the ?practicallegal method? and a minor empirical study has been conducted to find out howRegion Skåne and UMAS adjust their activities to the new regulations.The government aims to reduce sick leave and on March 19, 2008,the above mentioned bill was presented to the Riksdag. The bill is a part of thegovernment's package of measures and contains proposals for a revised sick-leaveprocess. The rehabilitation chain is a part of the package and includes actions witha tighter schedule.The employer is still after the new rules playing a central role in thesick-leave process and must through early and continuous contact with theworkers start the rehabilitation process.
Arbetskraftsinvandringens betydelseför samhället Gislaved : Berättelser om arbetskraftsinvandringen från Jugoslavien tillSvenska Gummifabrik AB i Gislaved 1962-1973.
Avsikten med uppsatsen har varit att ur ett arbetskraftsinvandringsperspektiv nå enfördjupad kunskap och förståelse kring arbetskraftsinvandringen till Sverige medsärskilt fokus på rekryteringen av utländsk arbetskraft till Svenska Gummifabrik ABåren 1962-1973, samt att utröna vilka effekter denna arbetskraftsinvandring har haftpå samhället Gislaved.Jag har genomfört fyra öppna intervjuer med jugoslaviska arbetskraftsinvandrare fråndenna period och sedan jämfört de tankar jag tagit del av med relevanta källor samtlitteratur om arbetskraftsinvandringens betydelse. Det gav mig förutsättningar att sehur den rekryterade arbetskraftsinvandrarens berättelser förhåller sig till allmäntaccepterad litteratur i ämnet. Jag kan därigenom se om förhållandet skiljer sig pålokal och nationell nivå.Studien har resulterat i en ökad kunskap om hur arbetskraftsinvandringen har gått tilloch motiverats av Gummifabriken när arbetskraftsbehovet var som störst. Detta harjag genomfört med hjälp av bevarat arkivmaterial, litteraturstudier samt dedjupintervjuer som genomförts. Undersökningens resultat visar att de invandradestankar väl stämmer överens med de källor samt litteratur jag presenterar ochundersökningen ger en förstärkt bild av redan skriven litteratur i ämnet.
Transition from nomadic pastoralism to livestock based agro-pastoralism : the case of animal husbandry in West Pokot, Kenya
West Pokot County is located in North Western part of Kenya where the previous lifestyle was nomadic pastoralism. However, in recent years the semi-arid county has been under
dramatic developments and a sedentary agro-pastoral lifestyle is now growing. This is a major change in production systems and there is a big knowledge gap especially for the livestock based agro-pastoral systems. The main objective of this study was to investigate
the current situation of animal husbandry in West Pokot. Twenty farmers were interviewed in Chepareria Division, using semi-structured interviews to investigate if the use of enclosures have had any effect on animal husbandry in West Pokot and if so, how have this method affected the animal husbandry? The results of the study indicated that there is a difference in animal husbandry between farms using enclosures and farms not using enclosures.
Anses endast ett bostadsinnehav tillräckligt för att medföra väsentlig anknyting till Sverige?
When unlimited tax liability exists, the individual is liable for all income, both which originates from other countries as well as from Sweden. In order for unlimited tax liability to exist the individual needs to either be considered a resident in Sweden, have habitual abode here or if previous residence existed, that the essential linkage still consists. To determine whether an essential linkage exists, the factors set out in the third chapter 7 § IL shall be considered, an overall assessment of all relevant circumstances must be made. In case law however, it appears that three of the factors have been given greater importance, one of which is the factor residence for year-around use, which includes both residence for permanent use and residence used for recreational purposes. The question raised in this thesis is whether the factor residence for year-round use is still regarded as a sufficiently strong basis to independently induce essential linkage for the taxpayer.A big difference between the two housing types exists.
LSD - Hallucination eller flödeseffektiv innovation
Increased competition in the IT industry has sparked a need for developing faster innovation processes with more predictable output. One of the biggest issues when it comes to achieving a faster flow through the innovation process lies in managing its high degree of variation. Proposing a solution to this problem, Lean Software Development (LSD), was developed to provide a framework for how IT companies should organize its software development process to achieve increased speed and quality. This study examines to which extent LSD, as a set of values, principles, methods and tools, can be used to improve flow efficiency in the innovation process. A case study of a multinational IT company was made by conducting ten semi-structured interviews with current employees.
