Hur formas ett inlärningsklimat som är framgångsrikt över tid? : En observationsstudie om fotbollstränares beteenden och träningsaktiviteter

Aim and research questionsThe over-all aim of this study was to gain insight info how two male coaches of a specific soccer team behave in a practice environment with regards to educating the players.More specifically, the study sought to map the extent to which said behaviour matched two specific methods of learning; these being Teaching Games for Understanding (TgfU) and Enhanced Guided Discovery (EGD). Research questions: (1) Do the coaches employ the methods and guidelines, which are outlined in the educational plan provided by the soccer association? If so, what form does this application take in practice? (2) To what extent and in what ways do the coaches utilize feedback and questioning techniques in the education of players? (3) What similarities and differences in behaviour can be identified between the chosen soccer team?s two coaches?Method: The data for the study was collected through field observation. The subjects were two youth elite soccer coaches and observation of these coaches took place during five regular practice sessions on the soccer field. All data gathering and analysis were carried out using a modified version of the Coach Analysis and Intervention System (CAIS).

Parallell beräkning av omslutande volymer

This paper presents techniques for speeding up commonly used algorithms forbounding volume (BV) computation, such as the AABB, sphere and k-DOP. Byexploiting the possibilities of parallelismin modern processors, the result exceedsthe expected theoretical result. The methods focus on data-level-parallelism(DLP) using Intel?s SSE instructions, for operations on 4 parallel independentsingle precision floating point values, with a theoretical speed-up factor of 4 ondata throughput. Still, a speed-up between 7?9 are shown in the computation ofAABBs and k-DOPs.

Nätet spinns vidare : Hur används Internet i ungdomsromanen?

The essay is a text centred study of ten Young Adult Novels, in which Internet plays an essential part. The structure is put into light out of used narrative techniques of how to create stories and its construction elements. I compare the ten Young Adult novels to each other. My aim is to analyze the functions of the Internet motive in the chosen novels, using different approaches, and enlighten it with concerns to the new phenomenon that Internet is in society. Consequently the essay will also have a mimetic touch to it.The ten novels that I base the analysis on are written of both med and women and have both male and female as main fictive persons, and are from different parts of the world.

De autistiska barnens dataprogram - hur bör de vara?

This report presents a study of the basic criteria for computer programmes that may be consideredadequate for aiding children with autism in their education and upbringing. I have based thisstudy on descriptions, opinions and proposals from people who deal with treatment and/orother issues concerning children with autism, as well as relevant literature.The study has been carried out in a major Swedish metropolitan municipality. The intervieweeswere civil servants from this municipality and representing different institutional endeavourson the issue of autism.I used a combination of both quantitative and qualitative techniques, as there was need for bothstandardization and qualitative variation. The main aim of the study was to seek suggestionson how computer programmes should be. That is, if they are to be considered appropriate föraiding children with autism develop their personality.The general conclusion of this study is that computer programmes, that may be consideredappropriate for the above mentioned purpose, should have certain characteristics of whichpedagogic usefulness and user suitability are of primary importance..

Elevers syn på klimatfrågan : Klimatundervsiningen i skolan

The aim of this study is to find out in which way the education about climate in school is taught and how the students experience the world situation today. There are various theories about the greenhouse effect and its origin and these theories should be addressed to ensure that students get a broader understanding of how climate change occurs. This includes the natural phenomena and also the human impact on climate change. Students in school are a source of concern that only human are the cause of global warming, and know little or almost nothing about the natural phenomena of global warming.  I will mention what has emphasized in the national steering documents in the case of environmental education at school.I have used a qualitative method, where interviews and document analysis were used as techniques. The interviews took place with five students in ninth grade and with three science teachers in the same school..

Motiv till att fortsätta föreningsidrotta : En enkätstudie om 13 till 18-åriga föreningsidrottande flickor

Pupils, and most of all girls, drop out of organized sports in the ages 13-18. The purpose of this survey was to study which motives girls had to proceed in sports together with differences between certain groups. This study was based on a survey which included 86 responses from girls active in sports in 10 different compounds. The results showed that the most frequent motives to do sports were to have fun and to feel well. Differences showed were that the ones who trained more often and the ones who practiced more than one sport found that to work hard was an important motive, compared to the other groups.

Mating behaviour and hierarchy among male warthogs (Phacochoerus africanus) in Kenya

Warthogs live under natural conditions in matriarchal groups, bachelor groups and yearling groups. Just like all pig species do warthogs have a complex behaviour repertoire. The semi-wild warthog population at Kichwa Tembo Lodge, outside Masai Mara National Reserve, lives in a fenced area with access to food all over the year and is protected from predators. The aim of this study was to observe the male warthogs? mating behaviour and their hierarchy during the mating season.

Magomvridning :

The purpose of the study was to review the current veterinary literature regarding gastric dilatation and volvulus (GDV) considering pathophysiology and treatment, and to evaluate the operative technique (incisional gastropexy) used during the years 2005 and 2006 at the University Animal Hospital (Universitetsdjursjukhuset), SLU, Uppsala, Sweden. GDV has a complicated pathophysiology which foremost effects the circulatory system. Progress is often acute and it is not unusual that patients are affected with shock. The initial treatment targets to alleviate the shock by fluid therapy and decompression of the stomach. There is a high risk of recurrence in the long term perspective unless the stomach is surgically fixated by gastropexy. The study describes two different techniques for gastropexy; incisional gastropexy, and funduspexy. Long term complications were rare among the patients that were treated surgically, while about half out of the eighteen dogs that undergo surgery do experience complications of various severity in the short term..

Förstagångsföräldrars upplevelse av BVC-sköterskans råd, stöd och information : en intervjustudie

Syfte: Syftet med föreliggande studie var att beskriva hur förstagångsföräldrar upplevde den information, de råd och det stöd som de erhållit av BVC-sköterskan. Metod: Studien genomfördes genom personliga intervjuer med sex förstagångsföräldrar med barn under ett års ålder. De första informanterna rekryterades genom ett strategiskt urval i föräldragrupper på utvalda vårdcentraler i en norrländsk kommun och för att få fler informanter användes sedan snowball sampling. Intervjuerna genomfördes med hjälp av en intervjuguide med tre frågeområden om förstagångsföräldrars upplevelse av BVC-sköterskans råd, stöd och information. Intervjuerna analyserades och tolkades genom systematisk textkondensering enligt Malterud (2009).

Effekten av kvävegödsling på gasproduktionen vintertid i boreala sjöar

To investigate effects of nitrogen on in-lake CO2 and CH4 production during winter, three pair of lakes was subject for a fertilizing experiment in which one lake in each pair was fertilized with nitric acid (HNO3) directly into the water column in the summer of 2012. The lakes in each pair are assumed to be morphologically, hydrologically and biologically similar, that is, the non-fertilized lakes are considered references. The pairs do differ in one major way by being progressively less humic, going from around 25 mg/l to 10 mg/l DOC. Sampling and analysis was carried out at the end of the frozen period in 2013. Results show a significantly higher concentration of both CO2 (p<0,001) and CH4 (?=0,1, p=0,053) between impact and reference sites in the two less humic pairs.

Effekten av ett probiotikum i en besättning med hög incidens spädgrisdiarré

Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.

Lakvattenrening och kontroll vid deponier : granskning och sammanställning

If not purified leachate from landfills would cause damages on the environment. At most landfills in Sweden local treatment of leachate is achieved, at the rest the leachate is transported to sewertreatment. While no comprehensive legal provisions for discharge exist in Sweden there is a difference in discharges between the installations for landfill. If no comprehensive legal provisions is produced guidance must improve.Treatment of leachate and self monitoring system at fifteen installations in Sweden has been studied and compared. A study of literature about different treatment solutions has also been performed.

Nanostrukturell ytbeläggning på utsatta delar av marina drivlinor

Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..
