Relativa ålderseffekter i skolan
Triathleter och cyklister är uthållighetsidrottare med extrem träningsvolym och stort krav på aerob kapacitet, dock krävs även anaerob- power och muskelstyrka för delmoment som backar och tempoväxlingar. Många uthållighetsidrottare tvekar över att implementera styrketräning i tron att effekten ska påverka deras prestation negativt, dessutom gör den höga träningsvolymen det svårt att kombinera. Styrketräning som komplement till uthållighetsträning har dock visats ge positiv effekt och kan förslagsvis förbättra prestation. Syftet var att undersöka huruvida ett styrketräningspass per vecka kan förbättra anaerob kapacitet hos cyklister och triathleter samt om en eventuellt ökad benstyrka kan påverka simtiden hos triathleter. Metoden var en interventionsstudie med pre- och posttest där deltagarna fick genomföra ett styrketräningspass innehållandes tre övningar, en gång per vecka under 12 veckors tid, som komplement till ordinarie träning.
Fysisk kapacitet hos poliser i yttre tjänst utvärderad med Coopers och Harres test
BAKGRUND: I andra delar av världen testas den fysiska kapaciteten hos yrkesverksamma poliser regelbundet. I Sverige finns inga tester eller krav på fysisk kapacitet på yrkesverksamma poliser efter genomförd grundutbildning. SYFTE: Att undersöka den fysiska kapaciteten hos poliser i yttre tjänst i Norrbottens polisdistrikt, för att påvisa om det finns ett behov av åtgärder för att upprätthålla yrkesaktiva polisers fysiska kapacitet. METOD: Förfrågan om frivilligt deltagande från poliser i yttre tjänst gjordes till delar ur Norrbottens polisdistrikt. Coopers test 2000 m och Harres test, vilka Polishögskolan använder i rekryteringsprocessen, valdes som mätmetoder.
Konsten att skrämmas : En studie om estetiska element i Friday the 13th part II och andra slashers
Swedish students' knowledge of both mathematics and reading comprehension has deteriorated in recent years. Scientists are discussing whether there is a connection between these areas and that the pupils deteriorating math skills may have something to do with their increasingly lower results in terms of reading comprehension. To investigate this possible connection, I conducted a survey among students in ninth grade and have come to the conclusion that the scientists are right: this connection absolutely exist. Students who received a high score on tasks designed to test students' mathematical problem-solving skills, also received high results on the reading comprehension test. And students who received a poor performance on the problem-solving tasks, were also low performers in the reading comprehension test.
Test av modeller för prioritering av förändringsförslag i Stora Enso Skog AB´s nya produktionsplaneringssystem VSOP
In order to evaluate the benefits and costs associated to investments in information technology (IT) managers need to be aware of the complexity in the nature of the task. Hence all the benefits that arise from the investment are not of pure economic character. The complexity of the task is even more obvious when managers also need to prioritize between a number of possible investments in order to fit a given budget.Stora Enso Skog AB is about to implement a new administration system to the organisation and due to that they will also implement a new standard system for the production planning process. In order to seek the modifications in the standard system that needs to be done to fit the organisations way of working, the managers have put together a reference group to seek out these modifications.The aim with this report is to identify a model that can prioritize these suggested modifications and test it practically with a group of future system users. The first part of the report is a literature study to map the existing models that are available.
Överpronation kopplad till ryttarens sits
According to ?Fotförbundet" (2012), Overpronation occurs frequently (80 %) in the Western World and furthermore overpronation of calcaneus influences the position of the pelvic and thorax (Fotförbundet, 2012; Behnke, 2008).
The aim of this study is to investigate whether or not it is possible to connect overpronation of calcaneus to the problem in the rider?s seat as observed by the instructors of Strömsholm. The study will also investigate if the riders seat problems as noticed by the riding instructors are comparable with the problems found by the analyst during testing. One purpose with the study is to raise the instructors and riders awareness that anatomical deviations in the rider might influence the rider?s position in the saddle.
The questions of the study are:
- Is it possible to see seat problems in riders with overpronation of calcaneus?
- If it is possible to see more seat problems in riders with overpronation of calcaneus, do the instructors in the study considers the seat problems be similar with each other?
- If there are seat problems in the study, is it the same according to the instructors and the analyst in human biomechanics?
The hypothesis of the study is that overpronation of calcaneus has an effect of the rider?s position in the saddle.
The study is conducted as a blind study where the test subjects have been filmed (from knees down) as they walked barefooted and later while riding.
Kan supplementering med omega 3 förbättra syreupptagningsförmågan hos idrottare?
AbstractTitle: Does supplementation with omega 3 improve oxygen uptake among athletes?Author: Jonna Gustafsson and Maria Bohlin Nygren Supervisor: Frode Slinde Examiner: Ingrid Larsson Programme: Programme in dietetics, 180/240 hp Type of paper: Bachelor?s thesis in clinical nutrition, 15 hp Date: May 26, 2015Background: Previous research has shown that omega 3 fatty acids may improve cardiovascular functions by decreased aggregation and increased red blood cell deformability. This produces an increased blood flow and could have a potential effect on oxygen uptake. Optimal aerobic capacity is a determinant factor of performance within endurance exercise.Objective: To compile scientific research of the possibility that omega 3 supplementation could improve oxygen uptake among athletes.Search strategy: The literature research is based on searches in PubMed and Scopus with the terms ?Physical Endurance?, ?Oxygen Consumption?, ?Fatty Acids Omega 3?, ?Dietary Supplements?, ?Exercise?, ?Fatty Acids Essential?, ?Docosahexaenoic Acids?, ?Eicosanoic Acids?, ?Fish Oils?, ?oxygen consumption?, ?maximal oxygen consumption?, ?VO2 max?, ?athlete?, ?omega-3 supplementation?, ?physical endurance?, ??-3?, ?omega-3?, ?Maximal Aerobic Power?, ?Oxygen Uptake?, ?VO2? and ?Maximal Aerobic Capacity?.Selection criteria: Randomized controlled trials (RCT) with an intervention of omega 3-supplementation during three weeks or more were included.

Annons eller PR : hur vet kommunikatören vad som skall väljas?
Problem Faith in the power of advertising has varied largely through the ages, and since we know that advertising is paid for, it therefore has less weight than the usual news. Publicity through promotional activities is in turn difficult to control. The question which of these two ways to communicate with the market that is the most effective, is equally entitled to ask, as difficult to answer. Purpose/Aim This paper is designed as a pilot study with two different objectives that go hand in hand. The first overall aim is to investigate how advertising and PR / publicity can be measured with the same tools while designing this metric.
Hjärtfrekvens och kortisolkoncentration hos valpar under olika typer av valptest :
The aim of this study was to find possible relations between behaviour and physiology for puppies during different parts of a puppy test. This work deals mainly with the physiological part of the study. Thirtysix puppies, från five litters, were tested in a behaviour test where heart rate was measured and saliva samples were collected before and after each part in the test. Saliva and urine samples were analyzed for corisol concentration as an indicatior of stress. The tests were performed during two consecutive days in the breeders' home when the puppies were seven weeks old.
In addition, heart rate and cortisol levels were also measured in the bitch since we were interested in finding out if there were any relations between physiological levels in bitches and puppies.
Verbbenämning hos svenska barn i åldern 3;6 till 5;5 år : En studie av prestation på Action Naming Test
Verbbenämning innebär förmågan att benämna en bild utifrån den aktivitet som bilden illustrerar. I tidigare studier har det visat sig att barn tidigt i språkutvecklingen har svårare för verbbenämning än substantivbenämning (Gentner, 1982; Kauschke, Lee & Pae, 2007). Detta förklaras delvis av att verb är mer lingvistiskt komplexa än vad som är fallet för substantiv (Gentner & Boroditsky, 2001), samt att de är svårare att illustrera (Masterson, Druks & Gallienne, 2008). För att undersöka benämningsförmåga används oftast bildbenämningstest och för verb saknas ett svenskt test för barn. Föreliggande studie syftade till att undersöka verbbenämningsförmågan hos svenska barn samt att utröna om den svenska översättningen av Action Naming Test (ANT) är tillämplig på svenska barn.
Troubleshooting the GFP-tagging gene knockout (GGKO) method for the Leptosphaeria maculans effectors AvrLm6 and AvrLm4-7
An attempt was made to GFP-tag the effector proteins of AvrLm6 and AvrLm4-7 using the GFP-tagging gene knockout method (GGKO) developed by Saitoh et al. (2008) in order to determine whether or not they are secreted. Successful pETHG-(target)KO vectors were not generated. The protocol was examined for potential errors. Fatal errors were pinpointed to the ligation reaction and the transformation required to generate and propagate the desired vector pETGH-(target)KO.
Utvärdering av Capcals förmåga att beräkna framkomlighet
Performance of an intersection affects the total travel time in a traffic network. An intersection with good performance can easily be described by its contribution to lower travel time than in a comparable intersection. The travel time is of importance in the cost calculations when a specific intersection is to be chosen and designed. It is important to be able to make correct and precise performance calculations so that the cost calculations will not be incorrect. For that purpose the software Capcal, which is a traffic model for intersection analysis on performance, is used in Sweden.
Testarbetets svåra val
När det talas om test pratas det på ett sätt som om det vore ett nytt fenomen, men i själva verket kan rötterna spåras tillbaks till 1978. Det är först på senare år som test har börjat etablera sig mer och mer och nyttan med test bland systemutvecklingsorganisationer respektive testorganisationer. Människan omges ständigt av information vare sig det är av elektronisk, fysiskt eller annan form. Det är därför inte så konstigt att tidsåldern människan befinner sig i kallas för ?informationsåldern?.
Kontext, utvärdering och användarupplevelse : En studie om kontextens påverkan på användarnas respons vid utvärdering av användarupplevelse
In this paper we explore the relations between context and feedback generated in three user-centered evaluations of a flash-based game. Whether it?s the social context, the physical context or the degree of intrusion from the evaluator, they all contribute to the quality of the feedback received. The selection of test subjects is a narrow process, which gives the above mentioned factors different meaning. Contextual factors have shown to influence the feedback given within both usability and user-experience.
