Sol, jord och vatten. : Barns tankar om den ekologiska processen

Studies show that the interest and knowledge about science among teenagers is decreasing. They also reveal the difficulties to explain the ecological processes and that the ideas about the nature are collected from everyday life and early school years.The intention of this investigation was to find out more about children?s ideas and knowledge about the ecological processes and to compare these results with the curriculum.The method was a questionnaire and interviews with children in school year 1 ? 6. The aim of the studies was also to find out if any progress connected to age could be found, concerning understanding of the ecological processes.The results showed difficulties in achieving the predestined goals for biology and chemistry concerning ecology cycles and they differed a lot between the children. Often the learning process showed very little progress.

Övervikt och fetma hos barn och ungdomar : Orsaker, konsekvenser och åtgärder

The purpose of this essay was to get some knowledge about how the situation was for children with overweight and obesity. I wanted to examine what experience about causes, consequences and measure the professionals, who meets children in different situations in their daily work had, and I wanted to find out which explanations current research had about the problem.The knowledge I have acquired during my work with this paper about the problem was that it was depending on many different factors on various stage in the child's life which influences and interacts with the child in its development. The risk that a child would develop overweight was amongst other things depending on the child's eating- and exercising habits.This habit was formatted for example by the circumstances in the family, availability of sweets/food and the choice of leisure time activities.The consequences for the overweight/obese children could be that the child did not manage to keep up with its friend's physical activities which led to a sense of rejection, risk of being bullied by friends, the risk of a damaged physical and psychic health. The problem was not easy to measure and all of the studies demonstrated that parental involvement is necessary in an effective treatment of childhood obesity..

Slemhinneskadors inverkan på salivens innehåll av IgG och IgA

In theory, the logic behind partnerships is simple: All organisations have strengths, but no organisation has all the strength required to do everything. Triggered by global perspectives and challenged by sustainability objectives, the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro in 1992 pointed out needs for corporate responsibility. In this conference, Private-public partnership, PPP, was identified as a potential way to work towards sustainability, especially as a way to emphasize a corporate responsibility commitment. Nowadays, organizations exist to satisfy the needs and interests of all their stakeholders, such as customers, markets, shareholders, as well as secondary stakeholders such as media, NGOs, and society at large. Addressing all stakeholders and working towards a sustainable business development makes PPP a potential solution, but also a source of challenges.

Flavan-3-oler och endotel -dysfunktion

Background: Flavan-3-ols are polyphenolic phytochemicals belonging to the flavonoids. Flavan-3-ols are present in many higher plants and are particularly concentrated in e.g. Camellia sinensis (tea) and Theobroma cacao (cacao) and have got attention due to their antioxidative capacity. Many studies have been able to associate flavan-3-ol-rich foods to improved endothelial function. The aim of the present work is to review the scientific literature and evaluate the evidence for positive effects of flavan-3-ols on endothelial dysfunction in humans. Method: Scientific articles describing intervention and observational studies about flavan-3-ols and endothelial dysfunction, were searched for on http://www.pubmed.org.

Barnen som inte fanns : En kvalitativ studie baserad på självbiografier med fokus på individers upplevelse av omsorgssvikt

The aim of this study was to describe and understand how individuals in adulthood experienced a childhood with neglect, and how they handled neglect. In order to reach the perspective of the individuals who grew up with neglect, we chose to use autobiographical books as our empirical material. The criteria the autobiographies had to meet in order to fall within the scope of this study was that the biographies had to display the experience of neglect during childhood, and thereto the books had to be written by individuals who themselves experienced neglect. Based on the aim of this study we sought answers to three questions: How do the individuals describe their upbringing with a mentally or socially disabled parent? How have the individuals coped with the neglect they?ve been exposed to? What consequences have the neglect supposedly led to? The findings of this study show that the extent to which the individuals experienced neglect were profound and comprising.

Konsumenters attityder kring livsmedel och livsmedelssäkerhet

Konsumenters attityder till livsmedel och olika aspekter av livsmedelssäkerhet undersöktes i en intervjustudie i Upplands län, i vilken olika frågor kring attityder till livsmedel med fokus på livsmedelssäkerhet ingick. Resultatet visade att det absolut viktigaste för konsumenter när de väljer varor är att livsmedlet smakar gott, då samtliga respondenter uppgav att detta var viktigt. Att konsumenter oroar sig mer för toxiska restsubstanser såsom läkemedelsrester och bekämpningsmedelsrester än för livsmedelsburen smitta framkom, liksom att få uppfattar sitt eget hem som en plats där man kan bli matförgiftad, trots att tidigare studier visat att en stor andel av matförgiftningsfall smittas i sitt hem. Oroande stora andelar av konsumenterna kunde tänka sig att äta olika livsmedel med förhöjd risk att drabbas av matförgiftning såsom otillräckligt upphettad kyckling, och ett flertal enkla men viktiga hygienåtgärder för att undvika korskontaminering uppfattas inte av konsumenterna som viktiga att utföra, vilket kan leda till onödigt många matförgiftningsfall. Djurvälfärd och livsmedelssäkerhet är beroende av varandra och aktuellt arbete visar att svenska konsumenter anser att djurvälfärd är viktigt..

Animaliska restprodukter vid köttproduktion : Effektiv användning och livsmedelspotential

This master thesis aims to investigate and quantify the potential associated with increasing the usage of edible by-products as food for human consumption on the Swedish market. The main emphasis is on the Swedish production of offal and the obstacles that currently inhibit greater usage of these products as foods.The results indicate that the Swedish market for offal is limited. Only a small amount of the edible by-products that are produced in Sweden every year are consumed as foods and a considerable amount seem to be downgraded into animal feed or thrown away. The utilization of these products is restricted by economical, technical, legal, and cultural factors that all need to be taken into consideration. On the whole, large-scale slaughter plants seem to be more inclined to utilize these products effectively, as the profit from doing so increases proportionately to the produced volumes.
