Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

Konditionstester i rehabiliteringssammanhang : - En litteraturöversikt

In some studiesit?s discussed if age related hearing loss or presbyacusis is a part of natural aging or if it depends on underlyingfactors.The purpose of this literature study was to analyse scientific papers which illustrate correlations between lessknown underlying factors and presbyacusis, defined from psychoacoustic and/or neurofysiological tests.Material and method; Literature study where scientific papers, relevant to the purpose of the study and thequestions at issue were found in the database PubMed.The result shows that cardiovascular disease, hormones, diet and drugs have an influence on presbyacusis. Thehealth condition of the individual and their lifestyle matters, likewise estrogen which according to the results of 2studies has a protective effect on hearing.Conclusion; The studies show that heart attack and high systolic blood pressure in women have a correlation topresbyacusis, but not in men, - the hormone estrogen, - some vitamins, antioxidants and diet have a protectiveeffect on hearing and studies show that smoking and alcohol have negative effects..

Om man inte klarar sig får man mer hjälp : Fyra elevers uppfattning om matematik och nationella prov i åk 3

AbstractThe intension with this paper was to describe the understanding students in third grade had about mathematics and how these students, based on their previous mathematics experiences, apprehend the coming national tests in mathematics. After the test period the student was interviewed on how they experienced their participation in the test. The choice of method was the qualitative case study where the data was collected from interviews and observations. In the result that was found, the interviewed students described mathematics as counting. Students preferred easy math work and to solve routine tasks in math books instead of more demanding work.

Nationella proven i matematik? en tillgång för läraren? : Hur några lärare använder sig av resultaten på de nationella proven i matematik

The purpose of this qualitative study is to investigate how some teachers make use of the results of the national tests in mathematics to plan their teaching. The questions are how they plan their teaching in mathematics and if they use the results of the national tests to compare with their own teaching.   Five teachers in mathematics has been interviewed. I have used unstructured interviews with open-ended questions, and I have been able to ask follow-up questions based on their answers. The analysis of the survey is made from a systems theory approach.  The result of the survey shows that teachers make use of student performance to look at their own teaching of the current group of students. However, there is not enough time to rehearse and repair the deficiencies discovered in the national tests, which for some is perceived as a stress factor.

Psykoakustisk påverkan av basfrekvenser : Blir vi påverkade av låga basfrekvenser som vi inte kan eller knappt kan höra med örat?

En kvantitativ studie om lärares inställning till och arbete med Nationella Prov : En enkätstudie i syfte att beskriva lärares uppfattning av huruvida NP bidrar till likvärdig bedömning och ökad måluppfyllelse i mellan ? och högstadiet.

The level of increased central government that we have experienced during the last decades in school, for the purpose of increasing equality and to adapt the Swedish school to a certain international standard, clearly shows that increased control scarcely leads to improvement.The aim of this paper is to examine whether teachers believe that national tests contribute to equivalent assessment and increased goal attainment. Furthermore the teachers? attitude towards and work with national tests is described. The paper is written from a school improvement perspective, where good examples from current research on what creates increased quality in school meaning increased goal attainment and equivalent assessment are related to research on school effectiveness and increased testing in schools. The study builds upon a quantitative survey among teachers in upper primary - and secondary school in a medium-sized municipality in Sweden.The result shows that the teachers have a somewhat more positive than negative attitude towards national tests, as a whole.

Physiological (heart rate and cortisol concentration in saliva) and behavioural responses in horses to four reactivity tests compared to the trainer's opinion about the horses? temperament

When performing studies that test the reactions of horses in different situations, important information may be available about the horse?s reactivity level. With information from these tests, accidents and dangerous situations may be prevented. When the behaviours from tests are compared with race performance it may be possible to evaluate if some behaviours are more desirable at the race track than others. The aim of this study was to see if behavioural responses correlated with physiological parameters (heart rate, cortisol), the trainer?s opinions and actual race performance.
