The aim of this thesis is to describe and critically investigate eight different evaluations of the retrieval effectiveness of webbased search engines. The questions to be answered in this investigation are: - What kind of relevance judgements have been used? - Which criteria have been used when judging the relevance of a document? - Which measures have been used? - How many queries have been used? - How were the queries constructed? - What document cut-off value has been used? - Has hypothes testing been applied? - What kind of webbased search engines have been included in the evaluations? The study showed that although the evaluations investigate the same phenomena, they are very different from each other in certain aspects. Generally the study showed that precision is the preferred measure in comparison to recall in the chosen evaluation even though all the included evaluations have constructed unique formulas for calculating precision. Some attempts to measure relative recall have been performed but they all suffer from different defects.

Syftet var att beskriva förekomst av risk för eller undernäring samt vanligast insatta och typav förebyggande åtgärder bland personer i särskilt boende samt att undersöka om det fannsskillnader i förekomst av risk för eller undernäring hos personer med neuropsykologiskaproblem jämfört med personer utan sådana problem. Studien hade en beskrivande ochjämförande design med kvantitativ ansats. Datat inhämtades från kvalitetsregistret Senioralert. Deltagarna i studien utgjordes av 341 personer från en kommun i Mellansverige.Resultatet visade att 41,9 % hade risk för eller var undernärda enligt MNA-SF. BMI <22poäng hade 23,5 %.

The aim of this thesis has been to examine how the risk for the swine flu was represented in the Swedish Radio news broadcast Ekot 16.45 during different phases of the pandemic in 2009. We wanted to study how the risk was described in different discourses and periods? Were the participants in the reporting calming or warning the listeners in relations to different aspects of the swine flu? What consequences for the community were reported in the broadcasting?To find the answers to our questions, we analysed 13 features about the swine flu broadcasted in Ekot?s main news broadcast Ekot 16.45. We used critical discourse analysis inspired by Norman Fairclough.We identified four types of discourses in our text, a journalistic discourse, a medical discourse, a nationalistic discourse and an authority discourse. The main discourse was the medical one.

It is well proven that physical exercise has an impact on our bodies as well as our minds. The aim of this study is to examine if this impact also affects economic behaviour. Three hypotheses regarding the impact of acute exercise on overconfidence, risk enhancement and well-being have been tested by collecting questionnaires from 364 participants at Friskis & Svettis, Kungsholmen who all were asked to answer the questions either before or after exercising. The differences between the before and after group were analysed, indicating small increases in all three test areas after exercising. These increases were, however, not large enough to reject any of the null-hypotheses of zero effect on the given five per cent significance level.

In recent decades, demands has emerged that the companies shall take a greater social responsibility for the impact that they have on their environment and that this impact shall be reported, which is known as Sustainability Reporting. The Sustainability Report is based on a number of general principles that ensure the content and the quality of the Sustainability Report. One of these principles is the principle of completeness. In the research, this principle seems to have been interpreted in terms of number of reported aspects and indicators, which can be a limited view where only the existence of the aspects and indicators is observed. By including the degree of the reporting in terms of full, partial and no reporting as well as a comparison between the real and the alleged reporting, our intention is to extend the principle of completeness and to develop a tool that we also apply through an empirical survey in a particular area.

Äldre patienter som har risk för undernäring eller är undernärda är vanligt förekommande på svenska sjukhus. Syftet med denna litteraturstudie var att beskriva vad sjuksköterskan kan göra för att förebygga undernäring hos äldre patienter (65+) på sjukhus. En beskrivande litteraturstudie genomfördes där författarna granskade elva vetenskapliga artiklar. Artiklarna söktes i databaserna PubMed och Mosby´s index. Resultatet i studien visade att det finns flera olika mätmetoder för att upptäcka undernäring eller risk för undernäring hos äldre patienter inneliggande på sjukhus.

This review paper summaries scientific research about horse thermoregulation and the consequences of using a blanket. Horse owners put blankets on their horses to protect them when they are clipped, to protect them from bugs, to keep them clean and so on. This can have consequences for the horse which their owners might be unaware of. I have tried to answer following questions by searching the available scientific literature; ? How can the horse maintain thermoregulation? ? Is there a risk of suffering when horses wear a blanket? ? Is there a risk of suffering when horses do not wear a blanket? ? How can animal inspectors estimate the welfare of horses when they wear or do not wear a blanket? My result shows that horses who wear a blanket have an increased risk of becoming overheated, develop a chafing, have an increased exposure hazard and have a restrained natural behaviour.

Purpose: The purpose of this study has been to investigate whether Frennberg & Hanssons earlier study of anomalies still are correct, and if these are valid for certain sectors. Methodology: In an effort to find seasonal patterns on the Swedish exchange market, we have used the average daily returns. By using these patterns we have created investment strategies which have then been tested over a 10 year period. We also used t-tests to verify our results. Conclusions: We have been able to prove a change in the seasonal patterns that Frennberg & Hansson presented in their study.

Bakgrund: Företag utsätts dagligen för olika former av risk och osäkerhet. Efter2008 års finanskris där många företag hamnade i finansiellttrångmål, då det var oförberedda på finansbubblans konsekvenserblev riskhanteringen inom tjänsteföretag mer uppmärksammat. Huridentifierar och hanterar egentligen tjänsteföretag operativ risk ochtill vilken grad använder dem sig av försäkringar? Och hur förhållersig den praktiska riskhanteringen i relation till akademisk teori?Syfte: Syftet med denna uppsats är att skapa en djupare förståelse i hurtjänsteföretag identifierar och hanterar operativ risk med hjälp avolika försäkringar och sedan jämföra med teori gällanderiskhantering.Metod: En kvalitativ fallstudie som bygger på intervjuer riktade mot ettspecifikt företag för att djupare kunna studerariskhanteringsprocessen och deras hantering i form av försäkringar.Vi har även valt att komplettera med information från företagetsårsredovisningar.Resultat: Resultatet av vår undersökning styrker den teoretiska kopplingen tillpraktiken. När det kommer till begrepp som risk, riskhantering ochriskhanteringsprocess anser vi att det finns ett starkt sambandmellan teorins tolkning av dessa och den praktiska tolkning samttillämpning.

As a consequence of a turbulent financial market with recurring recessions, the Basel regime was developed, an institutional change with the purpose to create enhanced financial stability through increased capital requirements and increased scrutiny of internal procedures. The Basel regime is an often recurring element in social debates where various aspects are discussed, one of which is whether it maintains its purpose to secure financial stability or whether it is cost effective, and if not, who gets affected by these potential costs.The majority of previously conducted research within this area agrees with the opinion that changes in the regulatory framework within the financial markets, such as the Basel regime, has led to reduced risk of bankruptcy for the banks which has contributed to increased global financial stability. However, research illustrates that these types of changes in the regulatory framework impose a financial burden leading to contradictions in the division of these costs between costumers and shareholders. This dissertation has been conducted from a shareholders perspective, out of which the study ?s three hypothesis has been created from.The data in this study is built upon the stock price from the three largest available banks? shares (based on total assets), in the 26 countries which are represented in the Basel committee from (2007) to (2013).

This Thesis aims to explore how to integrate an IT-system for facilitating anorganizations work with Continous Impprovements.This is done here by examining and analyzing the process within a handful ofcompanies who seem to have been successful with their own implementations. Thestudy is focused on the implementation of one particular system, "System C2".Simliarities and differences between the companies, and the established rule of thumbfor these kind of activities are focused upon. This to emphasis how another actormight emulate some of the apparent success.Part of the core question is found in the title, since Continous Improvement is oftenseen as a relativly low-risk activity, is it then also possible to take a low-risk slow pathto the implementation of such a system in the entire organization?.

The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue, both internationally and in Australia. With one of the largest dependencies on fossil energy sources in the world, the country's abundant solar radiation is a possible solution to this issue.Both the technical and the economic feasibility of small-scale PV systems were investigated. On the technological side, the electricity generation, distribution and consumption systems were studied. On the economical side, the parameters that drive the profitability of a PV investment were investigated.

Bröstcancer är en sjukdom som ofta bringar lidande och är viktig att förebygga. Utövande av fysisk aktivitet har i tidigare studier visat sig ge en minskad risk för att få bröstcancer. Litteraturstudiens syfte var att skapa en översikt över sambandet mellan fysisk aktivitet och bröstcancer hos kvinnor. Sökning, urval och granskning av artiklar har utförts. Resultatet visade att fysisk aktivitet hade ett starkt samband med minskad risk för att få bröstcancer för både pre- och postmenopausala kvinnor.

Pressure ulcers cause a lot of patients unnecessary suffering. This suffering could be decreased through improved knowledge about prevention, so that pressure ulcer will not appear. The purpose with this review was to study how nurses assess risk and prevent pressure ulcer, and to study how nurses use available knowledge. The method consisted of searches in databases and searching trough references. Our result is based on ten articles, qualitative, quantitative and reviews.

Aim - To investigate the prevalence of allergies among students at The Swedish School of Sport and Health Sciences (GIH) in Stockholm and relate it to factors that previous research in this area found to influence the risk of developing allergic diseases.- Can Hygiene Hypothesis or more specifically the relationships of family structure, socioeconomic status and the degree of overcrowding explain the existence of allergies among students at GIH?- Can the prevalence of allergies among students at GIH be explained by any of the known relationship for the prevalence of allergic diseases this study has taken into account?Method - Quantitative survey of students at GIH in the fall of 2013.Results - 214 students from The Swedish School of Sport and Health Science participated in the study, with representation from the first - and last - year students of all educational programs. More than twice the proportion of those diagnosed respondents said that their mother smoked during pregnancy or while they were breast-fed compared with the same group of respondents with no allergic diagnosis. The correlation is not statistically significant (p -value: 0.054). The majority of respondents with an allergic diagnosis indicated that their home mopped once a week or more for most of their childhood, while the majority of respondents with no allergic diagnosis stated that their home mopped less often.
