Effekten av Bisfenol A (BPA) på hanråttors (Rattus norvegicus) reproduktion

Today Evidence exist that environmental chemicals deteriorate male sperm quality and that testicular cancer is increasing. Bisphenol A (BPA) is a chemical with estrogenic effects used in the manufacture of polycarbonate plastic and are found in, for instance, plastic boxes, feeding bottles and food containers. Much of the research on how men's reproductive ability is influenced are performed on rats. This review article complies how male rat reproduction is affected by BPA as a model for humans. Studies have investigated how sperm are affected, hormonal changes during reproduction and how reactive oxygen species (ROS) affects sperm.

Y-OQ 2.0 SR : En studie om behandlingens villkor och att tillämpa mätinstrument i behandling av ungdomar

The Youth Outcome Questionnaire 2.0 Self Report (Y-OQ 2.0 SR) has been implemented in residential treatment centre in the Municipality of Örebro as a result of the strive for a more Evidence-based working approach within social work. This study aims to examine how personnel and adolescents describe the treatment/counseling and support and the application of the Y-OQ 2.0 SR in the units. The questions cover the values the personnel and adolescents ascribe to the application of the Y-OQ 2.0 SR, if the result from Y-OQ 2.0 SR is congruent with how the adolescents have been affected during the placement, which obstacles and/or possibilities emerge in the management of the instrument and if there are any indications that the Y-OQ 2.0 SR is advantageous or disadvantageous in the treatment process. The study has a qualitative approach; four interviews were carried out with adolescents and five with personnel. The result shows that structure is an important component in attaining a change in behaviour.

Jämförelsestudie mellan AP-fondernas Sverigeportföljer och storbankernas Sverigefonder 2002-2006

The first four AP-funds have a well-diversified Swedish portfolio, which is managed in similar way as the largest Swedish bank funds. Up until today, there has not been any comparable study that focuses specifically on this part of the AP-funds. Our aim is two-folded; First we will look at how well the AP-funds have managed their Swedish assets compared with Swedish funds of the four largest banks in Sweden during 2002-2006. This will be done by looking at some important key ratios and both absolute and active return. Secondly we will present a descriptive analysis of the management structure within the respective organisations, to be able to draw conclusions regarding the possible deviations in investment return.

När förmänniskan blev den moderna människan

The subject of this bachelor-level thesis in archaeology in the transition from archaic sapiens to anatomically modern humans, and what might have caused this transition. A part of the study aims to prove or disprove whether an increased consumption of shellfish might have caused this development. Another part of the essay deals with the connection of said evolution and the suggested emergence of cultural and ritual practices in South Africa circa 100 000 BP and an evaluation of the arguments concerning the aquatic ape hypothesis, and their usefulness for the subject.The result of investigation of the theory about the increased consumption of marine resources as a probable cause of the last biological step of creating our species points to the conclusion that it is a probable explanation. There is even some Evidence that there could be a connection between consumption of marine resources and the "Out of Africa 2"-theory. It is harder to find a proven connection between the suggested emergence of cultural and ritual practices, even some Evidence seems to strengthen the idea.

"Mamma vann, hon klarade allt!" : Barns upplevelser av föräldrastödsprogrammet Komet

AbstractEvidence based research has shown that organized parent support programmes have a goodeffect in strengthening the role of the parent and preventing problems during growth. Thisin turn has a great significance for Public Health.Komet is one of the Evidence based programmes used in Sweden, based on Americanprogrammes and adapted to Swedish conditions.This qualitative study consists of interviews with six children between six and nine yearswith behaviour problems, whose parents have taken part in the Komet programme.With Grounded Theory as research approach the children?s experiences of the programmeand relations within the family have been looked into and analysed.The result of this study suggests that a space for growth of their own is a common need ofthe children, and that this can be achieved by giving them the opportunity to function in afamily environment where they are seen and understood.The Komet programme contributed to this by giving the family tools to strengthen relationswithin the family, create calm and make the children more visible.The self image of the children in this study had improved which gave them more room togrow in a strengthened family situation. This in turn improved conditions for good feelings,and sense of well being, of importance for child development and health..

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Trans fatty acids from ruminants - and its effect on blood lipidprofile in healthy men and womenAuthor: Sophie Berg and Sara KarlssonSupervisor: Henriette PhilipsonExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2012BackgroundCardiovascular disease is the most common cause of death in Sweden. It is well known that thereis a link between high consumption of industrial trans fatty acids and cardiovascular disease, buthow natural trans fatty acids affect us remains uncertain.ObjectiveThe purpose of this article is to, based on the currently available scientific Evidence, concludewhether an intake of trans fatty acids from ruminants generates an effect on the bloodlipid profile of healthy men and women.Search strategyRCT articles were obtained through searches in databases such as PubMed, The CochraneLibrary, and Scopus. Keywords used were "ruminants" AND "Cholesterol" AND "Trans FattyAcids" and "ruminants" AND "Blood Lipids" AND "Trans Fatty Acids".Selection criteriaInclusion criteria were RCT studies conducted on healthy people who did not receive medicationfor hyperlipidemia. Moreover, the results were to be based on fasting blood samples, where atleast ten hours of fasting preceded the analysis of the blood lipids.Data collection and analysisThe search generated eight studies. These were graded according to SBU:s Granskningsmall förrandomiserad kontrollerad prövning, after which four studies were selected.

Kognitiv beteendeterapi vid morbid svartsjuka: med psykoedukativt tillägg baserat på evolutionspsykologisk teori

Morbid jealousy is a relatively common problem that often results in relational conflicts, frequently involving violence. Eventually many relationships break down as a consequence of these conflicts. Despite of this morbid jealousy is considered to be under-researched. As regards the treatment of morbid jealousy there is however some Evidence that cognitive behaviour therapy is a worthwhile treatment, and there is also a growing body of Evidence that jealousy, normal as well as morbid, is an evolutionary adaptation. This study integrates an evolutionary psychological approach with cognitive behaviour therapy in the treatment of morbid jealousy.

Med avfall upp till knäna - En osteologisk studie av tafonomi och medeltida avfallshantering i kvarteret Blekhagen i Lund

The subject of this master level thesis in historical osteology, is a study of waste management in the medieval town of Lund. The aims of the study is achieved through looking at the taphonomic aspects of bonefragments from the quarter Blekhagen. The study is divided in two separate sections, one that is a litterature study of what is known about waste management, and another one that contains a taphonomic and spatial analysis. Through examination of the taphonomic variables weathering, average weight and trampling and a spatial analysis, I am able to deduce that there are signs of controlled waste management in the material. It is not possible to draw any general conclusions about waste management in the medieval town however.

Aquaculture : animal welfare, the environment, and ethical implications

The aim of this review is to assess the ethical implications of aquaculture, regarding fish welfare and environmental aspects. The aquaculture industry has grown substantially the last decades, both as a result of the over-fishing of wild fish populations, and because of the increasing consumer demand for fish meat. As the industry is growing, a significant amount of research on the subject is being conducted, monitoring the effects of aquaculture on the environment and on animal welfare. The areas of concern when it comes to animal welfare have here been divided into four different stages: breeding period; growth period; capturing and handling; and slaughter. Besides these stages, this report includes a chapter on the current Evidence of fish sentience, since this issue is still being debated among biologists.

Naturlig nedbrytning av klorerade lösningsmedel i grundvatten

Chlorinated solvents are common contaminants in soil and water. Under anaerobic conditions microbes are capable of transforming chlorinated solvents into ethylene which would result in a remediation of the contaminated area. In order to use natural attenuation as a remediation method Evidence of continuous degradation is required. Furthermore, the degradation must occur at a sufficient rate and continuous monitoring of the site is needed until the demanded levels are achieved. A field study was performed on the basis of data from a dry-cleaning facility contaminated mainly by perchloroethylene.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Is pricing a way to affect share of fruits and vegetables in a diet?Author: Maria PopovSupervisor: Heléne Bertéus ForslundExaminer: Ingrid LarssonProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2013Background: Fruits and vegetables (FV) are important for health, including occurrence of diabetes, obesity and cardiovascular diseases. Said diseases cause most cases of illness and death in high-income countries. Only a small part of the population achieves the FV-intake goal, so a higher FV-intake is desirable. Besides general information campaigns there is another method of influencing what people might buy.Objective: To examine whether different pricing is connected to FV-intake or ?purchase.Search strategy: Databases PubMed, Scopus and Summon were searched with ?vegetable consumption", "price/pricing policy" and "food choice? in different combinations.Selection criteria: Studies performed after year 2000 on at least 18 years old persons from North America, Europe or Australia, examining changes in FV-price and -purchase.

Etisk organisationskulturs inverkan på revisionskvalitet i företag

In today's society there is tougher climate both financially and time wise. Accountants working under tight deadlines leading to the compromise between quality and quantity in the audit process and them therefor are being guilty of so-called reduced audit quality, RAQ. Reduced audit quality involves intentional actions designed to somehow reduce the Evidence contained in the audit. We examine in this study the impact of time budget pressure (TBP), underreporting of time (URT), ethical organizational culture and charismatic leadership has on the frequency of RAQ.Previous research has already shown that there are clear links between TBP and RAQ, between URT and RAQ and between ethical culture in organizations and audit quality available. Five hypotheses were designed to the study.

Faktorer som påverkar sjuksköterskans användande av evidensbaserad omvårdnad - en litteraturstudie.

Sjuksköterskor är den största yrkesgruppen inom hälso- och sjukvården, de har en viktig roll och potential när det handlar om att arbeta utifrån forskning samt med hjälp av den utveckla vården. Studier visar dock att sjuksköterskor utnyttjar tillgänglig forskning i begränsad omfattning. Syftet med litteraturstudien var att beskriva faktorer som hindrar och, eller främjar sjuksköterskans användande av evidensbaserad omvårdnad. Sökningar har skett i databaserna CINAHL och PubMed med sökorden Nursing practice, Evidence based/Evidence-based nursing som ämnesord och Barriers, Facilitate, Implementation och Utilization som fritextord. Därigenom har totalt 14 vetenskapliga artiklar identifierats, vilka litteraturstudiens resultat bygger på.
