Förskolebarn med externaliserade och internaliserade problem är ingen homogen grupp
Some children develop externalizing and internalizing behavior problems at an early age. Previous research has often treated these children as a homogeneous group, the purpose of this study is to show that this group of children is in fact heterogeneous. Data from theSOFIAstudy was used and preschool pedagogues were informants. The sample contained 2121 boys and girls between 3-5 years. Groups of children with the behavior problems and the risk factors AD/HD symptoms, fearlessness and callous-unemotional traits were created.
Cellulosa : en alternativ isolering med hänsyn till brand och fukt?
AbstractThis master thesis was performed at Scania transmission department in Södertälje, where the manufacturing of gears is done. Today a large amount of manual handling is performed between the machining and the hardening process. Most of the manual handling is done at the heat treatment department. The purpose of this master thesis is to give a suggestion on how to reduce or eliminate the manual handling at the heat treatment department. The possibility to use the same packaging throughout the processes will also be investigated.
Förekomst och förebyggande av ergonomiska besvär och hudbesvär inom frisöryrket i Gävleborgs län : En webbaserad enkätstudie
Bakgrund: Felaktiga arbetsställningar utgör ett dominerande arbetsmiljöproblem inom frisöryrket. Ett stort problem är också kemiska preparat som orsakar hudirritation och handeksem. Frisörer arbetskadeanmäler oftare belastningsskador och uppger oftare hudöverkänslighet än personer i andra branscher.Syfte: Syftet med studien var att beskriva i vilken utsträckning som ergonomiska besvär och hudbesvär förekommer på frisörsalonger i Gävleborgs län och om förebyggande åtgärder vidtas för dessa besvär.Metod: Detta är en retrospektiv tvärsnittsstudie med kvantitativ ansats med deskriptiv dataanalys. En webbenkät har skickats ut till 87 frisörer i Gävleborgs län, 50 personer har deltagit.Resultat: Resultatet visade att 36 av 50 personer uppgav att de hade ergonomiska besvär, främst från axlar/skuldror och nacke vilket förekom hos 25 personer. På de flesta salonger uppgavs att det fanns hjälpmedel för att förebygga besvär från nacke, axlar, skuldror, rygg och nedre extremiteter.
Textens inverkan på matematiska uppgifter : En undersökning om elevers textförståelse av matematikuppgifter i årskurs 5
The purpose of this study is to show the importance of task texts for students in grades 5 when solving mathematical problems. It was conducted in a class 5 (where the children are 11 years old). The pupils were assigned two different tests with mathematical problems; one where the problems were described in text and one where the problems were presented with numbers and mathematical signs. Previously done research, done on bilingual children, (Bernardo, 2002) shows that pupils tend to do better on mathematical tests when no text is presented. My research supports that theory even though the correlation is not that strong.
Matproblem och personlighet
The purpose of this study was to examine by means of Eysenck Personality Inventory (EPI), the relationship between Neuroticism, and self-rated eating problems. Altogether 105 respondents, mean aged 42,3 years, including 11 men and 94 women, participated by answering an Internet-based questionnaire comprising three different sections. Neuroticism correlated with self-rated eating problems (r=,468, p.
Utvärderingsmodell för förpackningar och dess hantering i dagligvaruhandeln : ? en jämförelse av ergonomi-, miljö- och logistikparametrar
Companies become more and more aware of the added values of the packaging. A well chosen and developed packaging can reduce the costs for the companies through reduced costs for transports, reduced quantity of waste and discards and increased goodwill for example. The companies? costs for salaries can also be reduced due to the increased packaging handling efficiency and the reduced costs for sick leave, reduced work capacity and rehabilitation etc. that can arise when handling poorly developed products and packaging.
Beteendeproblem hos hund som kan leda till avlivning
Too many dogs are euthanized because of different kind of behaviour problems today. Is it really necessary? Who has the main responsibility for this action? Do breed differences matter when it comes to increased risk of euthanasia of the dog? The purpose of this piece of work is to find the answers to these questions and also to find out what kind of behaviour problems that can lead to euthanasia of dogs in general.
The most common reason for dogs being euthanized is aggression. The aggression can be directed toward humans or other animals, mostly other dogs. There are some important factors of the dog that increases the risk of being euthanized, and these are the breed, the gender and sexual status and also the size of the dog.
FÖRBÄTTRAD MONTERING OCH DESIGNAV BAGAGELUCKA
This thesis includes a mechanical engineering design work performed incollaboration between ÅF and Halmstad University. The work is done by FredyOlsson?s methods of Principle- and Primary Construction and David Ullman?stheories of Design for Assembly.The group was commissioned by ÅF to produce a concept to narrow down theassembly time of today?s luggage doors by reducing the numbers of adjustmentoptions. They also wanted it to be easier to mount the assembly by making itpossible to adjust the door in a closed position. Today luggage door takes, with its10 adjustment possibilities, around 4 hours each to assemble and ÅF wanted anassembly time around 10 minutes per door.Initially a preliminary study was made where the group began reviewing today'sconstruction and mounting of rails and doors on buses.
Analys och omarbetning av ett företagsnätverk
In this paper, a small business network with around 30 users is analyzed with respect to security, performance and usability. Based on this analysis, two suggestions on how to solve the problems listed are given. The first suggestion focus on keeping a low budget, while the other tries to deal with the problems more thoroughly. One advantage of the first suggestion is, in addition to not straining the company's budget more than nessecary, it does not involve too great changes in the way the network is used and administered. On the other hand, the smaller budget leads to certain compromises, and there is a risk that similar problems occur again if, for example, the company would grow.
Lyfta Lätt Tekniskt hjälpmedel för pakethantering
People working with handling parcels in terminals are often victims of musculoskeletal injuries. This is largely due to the hazardous lifting of too many parcels which are too heavy and unsuitable work postures. The human body?s ability to lift and grasp objects is so outstanding that developing a device with the same capability is very difficult.The goal of the project has been to develop a technical device that will improve the handling of parcels with regard to ergonomics. The area of concern was the lifting of parcels between the conveyor belt and the cargo space of the freight car.
Uppsamlings- och behandlingsvagn för smågrisar i samband med kastration
The study investigates the use of collection and treatment wagon for piglets in relation to castration. The importance of good and ergonomically designed tools in pig stables can probably reduce the risk of suffering from musculoskeletal disorders (MSD). During the last 20 years the number of pig farms has decreased and at the same time the herd sizes and the number of pig keepers have increased (Statistic Sweden (SCB) 2007). As a consequence, the pig keepers have more pigs to take care of, treat and neuter and spend more of their daily work in these large confinements. This also means that the repetitive work e.g.
Turismutveckling av en landsbygd : - En studie om landsbygders utvecklingspotential inom turismnäringen
AbstractThe tourism industry has evolved to a vital factor for destination development in rural areas. This study aims to see how the tourism industry can be seen as an opportunity for development in rural areas. To be able to develop, rural areas have to be restructured and this study presents the restructuring problems that rural areas usually face and how developing tourism can be seen as a solution to these problems. Five destinations of rural character have been investigated in this study in order to see how these restructuring problems are expressed and addressed through tourism. A key example has been used to provide a clearer image of how these problems and tourism are related to each other and how their interaction can create a positive development for rural areas in Sweden..
Ligger grunden till problem inom projekt i initieringsfasen?
Project management has been a very popular way of conducting information system development in the past years. Among all major information system developing companies today, almost everyone work in some form of project management. Our objective with this study has been to find out if there are any problems that begin in the early part of the project. Problems that, if they aren?t solved directly, can become bigger problems later on in the project.
Hur ser Läget ut egentligen? : En studie om arbetsmiljön inom byggsektorn
This study includes several purposes which are to describe the concept of working environment, explain who is responsible for its functioning and how the working environment should look like. Other purposes the study have is to investigate how the working environment is in both Swedish and the two investigated companies construction sites and to share some operators proposing measures for the shortcomings and problems that exist in the construction sector working environment. To achieve these purposes was a qualitative study made with unstructured observations, interviews and survey where three construction sites were observed. The result shows that the concept of the working environment cover many aspects and is essentially about the environment we live in and experience in our work and this environment can be both an indoor as an outdoor environment. In this work, the concept is divided into four areas; it is the physical, the ergonomic, the psychosocial and the chemical.
Att söka samhällsinformation. En användarundersökning
Citizenship information is defined as the information the citizen needs to be able to take part in and influence the society. Since it is a democratic issue that information concerning the citizens role in society really reaches the citizens, it is of importance to study how the citizens proceed when they have a need for this information. The aim of this Masters thesis is to investigate how our eight informers proceed when they experience this need in a non-work situation. We performed qualitative interviews. The most important part of our interviews was the introduction of some fictitious problems to the informants.
