Påverkar känslan av rättvisa/orättvisa resultatet på ett kognitivt test i en rekryteringssituation?
Syftet med den här studien var att undersöka om det finns någon skillnad i prestation beroende på om rekryteringstestet har en koppling mellan test och arbetsuppgifter och när denna koppling saknas. Ytterligare ett syfte var att undersöka om det finns något samband mellan en persons prestation och dennes uppfattning om testet. För att undersöka detta gjordes en enkätstudie. En enkät konstruerades som bestod av tre delar; den första delen beskrev ett rekryteringsscenario som deltagaren ombads sätta sig in i, den andra delen bestod av ett kognitivt test och den avslutande delen bestod av frågor angående hur rättvist deltagaren uppfattade testet. Resultatet visade att det inte fanns någon skillnad i prestation beroende på vilket scenario man tilldelats.
Användartester inom webbutveckling : Är användartester nödvändigt vid utveckling av webbplatser?
The aim of this study is to get a deeper understanding about user tests as well as answer the question about if testing for users is necessary at all times. I've done a comparison between what the literature says, and what a company says, about testing. The tests that's been in focus in this study is prototyping and card sorting tests. Prototyping aims to give the developer feedback about the design and check if there are any obvious problems with the design. A card sorting test can be used to get input about how information architecture should be constructed.
Anställningsotrygghetens effekt på självskattad hälsa, i hög respektive lågkonjunktur
The subject of this study was to research whether or not the effect of job insecurity on self reported health differs between good and bad times in the economic climate. Two different years of a national health survey from the Swedish institute of health (FHI) served as data, with 2007 representing good economic climate and 2009 doing the opposite. Both years consisted of data from a national health survey distributed to 20 000 random individuals in Sweden, where 2007 had 5738 valid cases and 2009 had 10 373. A quantitative method was used to determine the difference, consisting of a three variable cross tabulation with chi2-analysis as well as a model of binary logistic regression for each of the two years.The cross tabulation found a significant difference between the two years, with those reporting job insecurity having less of a chance to report bad health during the year representing bad economic climate. While the logistic regression showed the same tendency, the two years could not be significantly differed from each other in that part of the analyzes.With this in mind, the conclusion from the whole test was that no significant difference could be found between the years regarding the health effect of job insecurity..
Att berätta med ord och bilder: Relationen mellan återberättande och och bildsekvensering hos barn
Storytelling is a complex action that requires many linguistic and other cognitive abilities, like memory and attention. Resent research has shown a correlation between oral story retelling and picture arrangement among children with neurodevelopmental disorders. The present study analyzes if this correlation exists among a convenience sample of children from the general population. 77 children between 3:11 and 9:0 years old accomplished Bus Story Test and a picture arrangement task from WISC III. Significant correlations was found between picture arrangement and Bus Story Test?s subscores sentence length, subordinate clauses and information.
Optimism & Känsla av Sammanhang : En Jämförelse Mellan Tjänstemän och Kollektivanställda
We set out to compare two different categories of workers: the, so called, white- and blue collar workers. The studies aim was to measure if there were any observable differences between the two in means of optimism and sense of coherence. There are two tools created for measuring optimism and sense of coherence, the Life Orientation Test ? Revised (LOT-R) measures an individual?s level of optimism and Aaron Antonovsky devised a test for measuring an individual?s level of sense of coherence (SOC). Optimism is best explained like a way to measure anticipation, how an individual expect future events to fall out.
Bärförmågetillväxt i pålad friktionsjord
Piled friction soil show a set-up which is increasing with the time after installation. The cost could be reduced if the set-up had been taken into account when designing but in Sweden it is very unusual to do that. Previous studies showed that set-up can vary between 25 % and 75 % during the first 90 days after pile installation. This showed that the effect of the phenomenon is difficult to predict. A study involving five projects have been carried out by specifying certain parameters like pile type, method for pile installation and test method for measure the bearing capacity in friction soils located in Sweden.
Prevention av djup ventrombos med graderade kompressionsstrumpor ? Effekt, riktlinjer och rekommendationer : En litteraturstudie
Deep vein thrombosis (DVT) is a serious postoperative complication and nurses should therefore observe symptoms in an early stage and implement preventive provisions, for example use of graduated compression stockings (GCS). The nurse is also responsible for making sure that ordinate GCS tried and used correctly by the patients. The aim of this study was to investigate the latest research regarding the efficacy of GCS in prevention of postoperative DVT and if there are any incorrectness in usage. And assess guidelines and recommendations for the usage of GCS. Method: Literature review.
Stärkelsers funktion som konsistensgivare vid olika temperaturer i pulversoppa : en experimentell kvantitativ studie
More often consumers demand instant dry soup that can be prepared with a water temperature below 100o C, which is currently not possible, because the dry soup becomes too thin when using water with a lower temperature. In this study, various kinds of starch studies were made to optimize the starch used in the existing product to make it more viscous at both high and low temperatures. The result was that one of the two starches present in the existing product was retained by change in quantity as it contributed to important flavor parameters. The second was removed and replaced with a starch that made the product more viscous at lower temperatures. To find out if the new product differed from the existing product a viscosity measurement and a sensory paired preference test were made.
Hur förselektion av hästar till bedömning och tävling kan hanteras i avelsvärderingen
The Swedish Warmblood riding horse is a popular horse for sport in Sweden, and the breeding goal is to produce competitive horses in both show jumping and dressage. The breed has its origin in native Swedish cavalry horses but has been highly influenced by foreign stallions throughout the years. Breeding values are estimated based on the results from young horse field test, which are held for 3- or 4-year old horses, and competition data. The young horse field tests are highly correlated with later performances in competition. The total proportion of horses with own observations to include in the genetic evaluation are slightly under 50 %, and in most cases their pedigrees are known.
Utvärdering av Språklig Snabbedömning för barn i åldrarna 2:6-3:6 och 4-6 år
Bakgrund: Språklig Snabbedömning (SB) är ett språkligt bedömningsmaterial framtaget för att på kort tid (< 1 h) kunna bedöma ett flertal språkliga förmågor. Användningen är utbredd i Västerbottens läns landsting men den praktiska användningen av bedömningsmaterialet har inte undersökts systematiskt.Frågeställning: Är resultaten av Språklig snabbedömning jämförbara med resultaten från bedömningar gjorda med normerade språkliga bedömningsmaterial?Metod: Data samlades in från arkiverade testmaterial för att kunna göra jämförelser mellan SB och kompletterande test. Totalt ingick 62 barn i undersökningen. Analysen genomfördes kvantitativt och kvalitativt genom att undersöka rankingen i olika material samt detaljgranska skillnader och likheter i upptäckta språkliga fel.Resultat: Den kvalitativa utvärderingen av SB visar att materialet ger resultat som ligger i linje med normerade test.
FALSKA MINNEN OCH SJÄLVKÄNSLA - med utgångspunkt i DRM-proceduren
Does a person´s self esteem contribute in the process of creating false memories? Previous studies show that mood is related to false memories as well as to self esteem. This led to the focus of this study, to examine the relationship between false memory and self esteem. The question is examined by comparing the amount of false memories produced in the Deese-Roediger-McDermott (DRM) procedure with people´s scores on Rosenberg´s self-esteem scale. 59 people participated in a test with three different elements, a self esteem test and a memory test with both recollection and free recall.
Flotation therapy for downer cows : a retrospective study of cases treated with flotation therapy at the Large animal clinic at the Faculté de Médecine Vétérinaire at Université de Montréal
There are about 700 000 dogs in Sweden. Roughly 70 % of the dogs are purebred and registered in the database at the Swedish Kennel Club (SKC). The database includes records of birth date, pedigree, offspring and results from e.g. veterinary examinations related to genetic health programs.Every year approximately 10% of the dogs die; most are euthanized by a veterinarian. Dog mortality data is stored as digital medical records at animal clinics and in insurance databases.Dog owners tend to register their puppy in the SKC, but they rarely report that the dog has passed away.
Datakvalitet : En fallstudie om kvaliteten i SJ:s underhållssystem
SJ is a government-owned passenger train operator in Sweden. SJ currently uses asystem called Ford for control and monitoring of maintenance. Technical andorganizational factors have given Ford the character of a monolithic system withoutflexibility and conditions to meet SJ's increased requirements.The main purpose of this master's thesis is to investigate how data quality can bedefined at SJ and to examine the data quality in Ford. This will give SJ an indication ofwhat their quality efforts should focus on in the future.The technical data quality parameters found are: accuracy, timeliness, completenessand consistency. The user centred data quality parameters are: accessibility,understandability and reliability.
Vilka möjliga faktorer ligger bakom individernas varierande pensionsålder?
Fewer and fewer people from the age of 60 and upward are still in the working life according to a working survey from Central Bureau of Statistics. Only one of twenty can consider retiring after an age of 65. According to another survey that National Insurance Administration put through year 2000, just about 40 % of the working population desires to finish working before an age of 65. This trend towards lower seceding age seems to continue. There are number of factors that seem for lower retirement age and others for a higher retirement age that we prove in our study.
Let´s talk about sex: en studie av patienters uppfattning av samtal i samband med testning/smittspårning för sexuellt överförda infektioner med fokus på sexualitet
The aim of this study is to examine the patient's understanding of the counselling while testing for an STI. The method was an inquiry directed to patients at two receptions, where tests for STI are made, and on the Internet for patients who made a test within the last year. The study involves 95 participants, 39 answered the inquiry directly after the test. The main results show that most participants are positive to talk about their sexuality and sexual strategies with the personnel, irrespective of who takes the initiative to the counselling. Women are yet more negative then men to talk about their sexuality, even if the test is made voluntarily by the woman.
