Barngruppens storlek i förskolan ? en kvalitetsfråga? : Sex pedagogers reflektioner

This research is about six pedagogue´s and their reflections about the size of the children´s group in the preschools. Then I will discuss the pedagogue?s recommendation on the significance of the size of a children´s group learning and development and it´s practical significance for the preschool function. The pedagogue?s statements will be discussed in relation to The Swedish National Agency for Education (TSNAE) guidelines on group size.The theoretical framework of this essay will take an overview of the social cultural perspective, the group size and its significance for both the children´s learning and development, for interaction and communication and TSNAE advice and guidelines.

Variation in protein precipitation and phenolic content within and among species across an elevational gradient in subarctic Sweden

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

Fixering av suggor ? så påverkas välfärd och smågrisdödlighet

Piglet survival is a problem of great significance in pig production, affecting both animal welfare and economic aspects negatively. In Sweden it is illegal to use farrowing crates for sows on regular basis. To encounter this problem there is a proposal of an animal welfare program to allow the use of crates for sows during, and a number of days after, farrowing. The proposal aims to reduce piglet mortality and improve pig welfare. This present review aims to analyse how crating affects the welfare of sows, gilts and piglets as well as piglet mortality.

Textstorlekens påverkan

Purpose;the purpose of this study is to investigate whether a product ad observer's purchase intention, perception of product quality, brand image perception and price perception is affected depending on the size of the text that was used in the ad to communicate the product price.Methodology;the study was conducted using a quantitative method through a survey. The implementation of the study has been done by using three variants of the same suit ad where the three different variants have been manipulated on the text size on the price information, by reduced / increased the text size. The implementation has also been carried out using two different ad sender, with three ads for each sender.Result and conclusion;the text size on the price of a product ad mainly affects the observer's price and quality perception, where the small text will have a positive effect on quality perception and a negative effect on the quality perception. Even brand image changes depending on the text size where small text will have a positive effect..

Nedskräpade återvinningsstationer - En studie om fördelning av ansvar

In Sweden, responsibility for the collection and recycling of packaging and newspapers lies with the producers. Therefore, the major producers created a jointcollection with 5800 recycling stations. The stations are the responsibility of a coordinating body, Förpacknings och Tidningsinsamlingen (FTI) which ensures Government regulations are adhered to by the producers.In 2006, the Swedish Environmental Protection Agency (EPA) carried out an evaluation of the collection of packaging and newspapers. EPA´s research showedthat 80 percent of households were satisfied with the collection but that there were also shortcomings, including problems with littering at the recycling stations.We have tried to approach the litter issue from different angles in order to suggestpossible measures to reduce the problem. An important aspect proved to be uncertainties regarding the concept of operators.As there are currently many parties involved in the collection process this lead to the issue of who is legally considered as the operator of the recycling stations.

Påverkar suggors grymtande under digivningen smågrisarnas tillväxt? :

The pig is unique in the way that it gives birth to a large number of newborns in each litter. Because of this the sow has developed a special behaviour during suckling to ensure that not only a part of the litter gets all the milk. Milk is only available during milk letdown. The piglets have to massage the udder for a long time before letdown and the more piglets at the udder the sooner the milk comes. The sow has developed a special grunting pattern to let the piglets know when she is ready for suckling and to signal milk letdown. Our aim with this study was to investigate if sows have individual grunting patterns repeated over time. We also wanted to know if sows with a more distinct grunting pattern have better growth in their litters.

The genetic background of oxytocin and its importance for maternal behaviour of sows

Oxytocin is today widely spoken of as a "feel good" hormone. Recent research has increased interest in the hormone and its role in social and sexual interactions, as well as its importance for complex behavioral patterns. There is evidence that oxytocin is released during physical contact and is said to suppress anxiety and stress. In animals and humans, oxytocin, which is a neuropeptide and likewise a hormone, is necessary for parturition and lactation. Synthesis of oxytocin occurs in brain neurons and in specific organs involved in reproduction.

Äggstockens normala storlek och struktur hos tik :

There are only a few published studies on the normal variation in ovary size in bitches. All of the previous studies have been made on the beagle breed. This study was performed on indian street dogs with the objective to measure ovaries and structures in the ovaries after ovariehysterectomy to decide if smaller dogs have smaller ovaries and how small and big they can be in the normal dog. The structures (follicle and corpus luteum) where also measured to get a maximum size for normal structures in the bitch. This information can be valuable when examining the ovaries of the bitch with ulstrasound.

Födoval hos juvenil piggvar (Psetta Maxima) : effekter av bytesstorlek

The effects of prey size on prey choice in different cohorts of juvenile turbot (Psetta maxima)were studied in three nursery areas at Gotland. Prey length measurements showed that gobies(Gobiidae) increased in average length during the season, while mysids (Mysidae) did not.Experiments on predation capacity of different size classes of turbot on different size classesof prey showed that juvenile turbot easily can eat gobies that are up to two thirds of their ownbody length, while the body size of turbot does not have any effect on the predation capacityon mysids. Stomach content of 217 turbots, less or equal 35 mm, was analysed to see if therewas any change in diet during the season, but there was no significant change in diet. Theoverall conclusion was that early settlers most likely have an advantage due to greater accessof alternative prey..

Housing of ringtailed lemur, Lemur catta, from an ethological perspective

Sheep production is the only animal production in Sweden that is increasing. Therefore,increasing knowledge of the production is of great interest. In order to run a viable sheepproduction, producers needs to be successful in the breeding of the animals and achievean economic surplus in the end. Lambs that are born healthy and vital have greaterconditions to perform high lamb weight gains and thus a successful production. Thereare many factors affect the survival, birth weight and early weight gain of the new bornlamb.

Hassel (Corylus avellana) som indikator på markanvändningshistorik

Hazel (Corylus avellana L.) is a common feature of meadows and pastures where it can grow in large populations and become very old. Is it possible to use the size of hazel stools for age determination and is it possible to use the size distribution of a population to provide information about how the land has been used? Hazel populations on ground where the lake-water level had been lowered, has been studied to validate an already developed growth model of hazel clones. Different hazel populations, on wooded meadows affected by mowing or grazing or overgrown meadows, were studied to evaluate the method utilizing hazel as land use indicator. The growth model was used to compare the size distributions of hazel populations with historical periods, which has been important for changes in agriculture or demography.

Produktutveckling av en storleksreducerbar gästsäng

This report is a result of a degree thesis at Luleå University of Technology together with Stram AB in Växjö. The project aimed to develop a size reducible bed, that gets small when folded and has a new slim design. The development of the new folding bed had the purpose to give Stram AB new ideas of how guest beds can look like and be used in the future. Information about Stram´s products and also information of other similar products on the market was gathered. A visit at a store, internet and interviews gave grater insight of the market, and of customer needs.

En jämförelsestudie av JavaScript-bibliotek Med fokus på mjukvarukvalitet

JavaScripts popularity is increasing and the number of libraries too. This report focuses on well-known software metrics in complexity, maintainability and different size-metrics. A few different JavaScript libraries are compared and analyzed. The result shows that there are indeed differences, mostly in size- and complexity-measures where some functions are implemented with a higher complexity..
