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.

P/E-effekten : En utvärdering av en portföljvalsstrategi på Stockholmsbörsen mellan 2004 och 2012

One could argue that the most discussed topic in finance is whether or not it is possible to ?beat the market?. Even though many people claim to do this, there is little evidence to support the idea that one can consistently beat the market over a long period of time. There are indeed several examples of investors who have managed to outperform the market consistently for a long time, but the efforts of these individuals or institutions could by many be considered to be pure luck.One of the many strategies that have been evaluated by several researchers and is said to generate a risk adjusted return greater than that of the market, is one based on the P/E-effect. This strategy is based on the financial ratio P/E ? price divided by earnings ? and used by constructing portfolios consisting of stocks with low P/E ratios.

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.

VILKEN STRANDVEGETATION BIDRAR TILL DET ORGANISKA MATERIALET I KUSTN?RA SEDIMENT? Kols?nkor/k?llor, nedbrytbarhet och eDNA sp?rning

Coastal sediments are important carbon sinks, storing organic matter and thereby helping to reduce the amount of greenhouse gases in the atmosphere. However, they can also act as carbon sources if the deposited organic matter decomposes rapidly, contributing to increased greenhouse gas emissions and global warming. Rapid decomposition partly depends on the degradability of the material itself. In this literature review, I examine which coastal plant species dominate different locations along the Swedish coast, based on coverage data from the ClimScape project (www.climscape.se). For the most dominant species, I investigated the type of organic matter they may contribute to the sediments and based on those results I qualitatively assessed which sites that may function as carbon sinks or sources.

Hypercholesterolemia is one of the risk factors for cardiovascular disease. In Asia, hypercholesterolemia is less common than in the Western countries. In Asian countries, soy products are consumed in larger quantities than in the Western world, which has led to implemented research with the intention of examining soy's potential effect on cholesterol levels.Objective: To investigate whether there is scientific evidence that isoflavone supplementation from soy bean may have a lowering effect on LDL-cholesterol.Search strategy: The databases used for the systematic literature search were PubMed, Scopus and Cochrane. Keywords used were cholesterol and 9 versions of this, and isoflavones and 11 versions of that.Selection criteria: RCT articles, on humans, written in English, published from 2011 onwards, that focused on interventions with isoflavones from soybeans and its effect on blood cholesterol, the participants were over 18 years old and the study time was at least 24 weeks.

Ovidkommande vatten i spillvattensystemet - problematik och åtgärder

The purpose of this essay was to examine whether small businesses can avoid ac-counting crimes with a well-conducted internal control system. The questions we asked ourselves was, whether and if so, companies can prevent this from happening by using a internal control.In this essay we used a qualitative approach. Essential information was given to us from four different interviewees. We also worked from an inductive approach which means that we interviewed people without any earlier research to build on. The method also had a hermeneutical approach, which means that we made different interpretations based on the reference framework and the empirics.After the study had been carried out, we concluded that all evidence from this essay suggested that even small businesses need an internal control to protect their business.

dentÆd : Utveckling av medicintekniskt instrument som ökar säkerheten samt underlättar vid oral protetik.

Initiativet till projektet togs av tandvårdspersonal på Specialisttandvården i Halmstad då de upplevde problem vid arbete med oral protetik. Problemet, som projektet även bygger på, innebär att komponenter tappas och på grund av gravitationen samt patientens position riskeras att inhaleras eller sväljas. Detta innebär ett stress- och orosmoment, vilket bidrar till en försämrad psykosocial arbetsmiljö för tandvårdspersonalen. 2008 infördes det statliga tandvårdsstödet i Sverige vilket innebär en reducerad kostnad för protetikingrepp som lett till att fler har råd med oral protetik. Därför blir problemet mer och mer utbrett, vilket gjort kravet på en lösning mer eftertraktad. I projektet har dynamisk produktutveckling tillämpats med stort fokus på involvering av framtida användare. Artikelsökning, observation och enkätundersökning i genomförd produktdefinitionsfas lade grunden till projektet.

Vad kännetecknar en bra respektive mindre bra lärare? : En studie om gymnasieelevers syn på ledarskapskompetens i klassrummet.

The purpose of this project is to examine students' pespectives on quality in teaching. The characteristics that are described to denote a 'good' and 'less good' teachers are linked to ideas about types of corresponding leadership styles in the classroom. The report is based on surveys of students in Upplands-Bro high school outside Stockholm. In order to get better insight and further knowledge of the subject, the student accounts have been related to current discussions in the literature about good leadership and teaching quality.Following the methodology of grounded theory a pilot study was constructed to design the research instruments. In the pilot study I collected students' perceptions on quality-related categories in teaching and leadership which then formed a bases for a survey which was distributed to a larger student sample. The survey includes questions that relate to the middle order, which is based on three criteria that make up the characteristics of a 'good'/ 'less good' teacher and the leadership style that suits students descriptions of good teacher characteristics.The results of the study show that a good teacher should have subject knowledge, be good at writing and illustrating the curriculum on the whiteboard and explain and clarify their instruction through good communication.

A risk analysis of moose close to roads

For many decades the increase in traffic volume, expansion of highways and infrastructure has lead to an increase of wildlife vehicle collisions which are unfortunately very common in many countries today. They cause great deal of material damage and even kill humans or wildlife. Measures in the form of warning signs, under- and overpasses and fencing have been implemented for a long time with the help of observation by hunters and collisions sites. However this study focuses on the moose?s perspective and the variables that, both spatially and temporally, could have an effect on why and when moose are close to certain types of roads.
