Purpose: The purpose of this thesis is to investigate whether abnormal stock returns could be identified as a result of a layoff announcement during weak economy.Method: An event study methodology.Theory: Efficient market hypothesis, signal theory.Empirical results: Quantitative data from observations of stock prices in thirty two companies listed on the Nasdaq OMX Stockholm, in the period 2008 -2012.Conclusion: The results indicate that the market reaction was negative because there were negative abnormal returns on the Stockholm Stock Exchange during the period 2008-2012 in connection with the layoff announcements. The market reaction was milder when staff reductions were carried out as a result of a restructuring and stronger when staff reductions were carried out as part of a cost reduction program.The layoff announcements elicited different market reactions depending on the company's industry affiliation. The most negative reaction was in the Healthcare industry. Negative abnormal returns were lower in industries Industrials, Consumer Services and Consumer Goods. There were no abnormal returns for shares of companies in the industry Financials.

Background: Every year, more than 1000 cases of adverse events are reported in the Swedish health care system. These adverse events cost approximately 240 million Swedish kronor each year. By explaining the factors that cause nurses to make mistakes when they have too great a workload, it is hoped the awareness of health care staff will increase. Aim: To perform a literature review which describes factors that can endanger patient safety when nurses experience too great a workload. Method: A systematic literature review encompassing both quantitative and qualitative material.

This study was performed in order to evaluate if the method of collecting uterine secretion by the tampon-method is representative for use in studies of uterine secretions in mares. Uterine secretion collected by tampon in six mares was compared with secretion collected by aspiration, regarded to be a native sample, at the Institution of Obstetrics and Gynaecology, SLU, Uppsala. Proteinanalysis was made at the Department of Farmaceutic Bioscience, toxicological unit, Uppsala University. Cytological smears and ultrasonography was used to assess if the tampon had caused an inflammatoric reaction that could influence the protein content of the samples. The results suggest that the tampon and aspirat method do not differ when it comes to proteinconcentration, but the distribution of proteins differ between these different collection methods. This difference could not likely be explained by means of proteins due to an inflammatory reaction from the tampon, since neither the cytological nor the ultrasonographical examination gave any indications of inflammation.

The aim of this study is to examine how the public responds to the journalists? use of subjectivity in the reporting of broadcasting news. The investigation is a qualitative study based on nine interviews with respondents in ages of 21 to 25 from different parts of Sweden. After showing five examples of news reporting with a subjective approach, the respondents gave their look on the use of subjectivity. The theoretical frame of the investigation is founded on the theory of framing (de Vreese, 2005; Entman, 1993) and the discussion concerning the terms objectivity and subjectivity (e.g.

SAMMANFATTNINGBakgrund: Läkemedelsbiverkningar utgör ett stort problem för den enskilde som drabbas och för samhället. Distriktssköterskor med förskrivningsrätt har ett ansvar att rapportera misstänkta läkemedelsbiverkningar och spontanrapportering är grunden för läkemedelssäkerhet. Studier visar att det finns en hög grad av underrapportering. Syfte: Syftet med studien var att undersöka distriktssköterskors kunskap och förståelse om läkemedelsbiverkningar samt deras handlingsberedskap för, och syn på att rapportera dessa. Metod: Semistrukturerade intervjuer med kvalitativ ansats användes, sju distriktssköterskor i Jämtlands län deltog.

Tractors of today come equipped with a CAN-system. A CAN-system sends information from sensors to electronic control units who process the signals. The sensors measure several interesting parameters such as force, pressure and speed for various components of the tractor. This thesis discuss a force sensor which is placed in the pivot of the tractors three point linkage, the sensor measure the horizontal reaction force from the load that the tractor is exposed to. Signals from this sensor can be used to measure the force from any implement that the tractor is exposed to during an operation.

Bakgrund: Det är en vanlig arbetsuppgift för sjuksköterskan att följa upp effekt och eventuella biverkningar av läkemedelsbehandling för återkoppling till ordinerande läkare. I och med att sjuksköterskan i den kommunala äldrevården har en konsultativ roll, är informationen mellan henne och vårdpersonalen, som är nära patienten dygnet om, mycket viktig. Denna del av läkemedelskedjan är av central betydelse för att minska onödigt lidande för den äldre patienten i form av läkemedelsrelaterade problem. Syfte: Att kartlägga hur sjuksköterskan i kommunens äldreomsorg följer upp läkemedelsordinationer avseende effekt och biverkningar, särskilt i de fall när patienten själv inte har förmåga att uttrycka sitt mående i ord. Metod: En empirisk studie med kvantitativ ansats.

In this study I investigated whether the strength in the manual response for emotional and neutral stimulus search arrays can explain some of the difference in reaction times (RT:s) for emotional stimuli, or not. Earlier, perceptual, cognitive and attentional processes has mostly been used to explain the variance in RT:s. Thirtythree individuals were asked to, as fast as possible, detect a target picture among distractor pictures in 3 rows x 4 columns arranged search arrays. The pictures were categorized in fear relevant animals (snake, spider) and neutral animals (cat). The results showed, more correct responses for cat target.

This study investigated the relation between Extraversion and Conscientiousness with job satisfaction and job selection in the two occupational groups of telemarketing and administration. The study also set out to explore the relation between social desirability as assessed with an Implicit Association Test (IAT) and total reaction time on the IAT. The questionnaire was administered over the Internet to forty-one subjects (24 women and 17 men) in the age range 16-65. Results indicated that people working with telemarketing tend to be extrovert while people working with administration often are conscientious. Job satisfaction correlated with Extraversion in the telemarketing group.

Till alla godkända läkemedel skall bifogas information till vårdpersonal hur produkten skall användas säkert och effektivt. De metoder som används för insamling av data under en klinisk läkemedelsprövning, innan godkännande för försäljning, påverkar möjligheten att göra korrekta bedömningar av ett läkemedels bieffekter. Insamling av patientsäkerhets-relaterad data, ?incidenter? (?Adverse Events?; AEs), i kliniska läkemedelsprövningar är ett område förenat med många metodiska oklarheter och svårigheter. Internationella och nationella regelverk specificerar inte i detalj hur datainsamling skall utföras.

During the last years, producers and consumers have become increasingly aware of food safety. Foodborne illness and foodborne injury are in best case unpleasant but they can also be fatal. HACCP (Hazard Analysis Critical Control Point) is a preventative food safety system which is aimed to guarantee production of safe food free from pathogens, foreign materials and substances with potential to cause adverse health effect. In order to succeed in developing, installing, monitoring and verifying a HACCP system, there is a mix of hurdles for the company to overcome. While larger food companies meet a difficult challenge, small and medium size enterprises often feel that the hurdles are almost impossible to manage.

Endocrine disruptive chemicals (EDCs) are found in many everyday products and can cause adverse effects on human health. Small children are particularly sensitive to EDCs and they are also exposed to them in a greater extent than adults. Despite this, EDCs are only banned in a few toys and childcare products. There are many sources of exposure and if no steps are taken to reduce the incidence of EDCs we may face an increasing number of people diagnosed with obesity, diabetes type 2 or various types of cancer.The Swedish Government has set a number of environmental objectives, one of which is calleda non-toxic environment. The Swedish Chemicals Agency was instructed to produce and conduct a national action plan to achieve this goal.

A large part of the Iranian population resented the west, in particular USA and Great Britain, during the Islamic revolution in Iran 1979. The people were also resenting the adverse effects of the trumped up frame made in Iran. The last shah of Iran, Mohammad Reza Pahlavi was detested by many in Iran for its west-oriented regime. The resentment among many Iranians is a consequence of the violations of e.g. the lack of political and civil rights, there were no existing legal security in the society, there were no economic distribution and the regime of Mohammad Reza Shah violated the human rights.The resolution from an Iranian perspective for riot is not new, during the last centuries the abomination against the despotic kings have been existing varyingly and big riots have been raised.  The Islamic revolution in 1979 was new because the revolution added adverse effects of west, the population detested west and expressed it by protesting through demonstration.  The significance of the revolution in 1979 was also attributable to Islam.

Nuts of all kinds are common ingredients in food. For nut allergy sufferers the frequent use of nuts cause problems and "hidden" nuts in food products may elicit allergic reaction when such foods are consumed. Methods for detecting and quantifying walnut (and other nuts) with high sensitivity and specificity are therefore very important.The objective of this project was to verify the specificity of a rabbit antiserum against walnut with immunodiffusion and to determine the size of the dominant walnut antigens with Western blotting. In addition, a commercial sandwich ELISA for walnut quantification was validated and compared with a qualitative real-time PCR.The rabbit antiserum proved to be less specific but after absorption with cross-reacting nuts and seeds it showed high specificity. The ELISA kit reacted, except for walnut, with pecan and slightly with other nuts and seeds tested.

Bakgrund: Kontrastmedel är ett flytande medel som injiceras i kroppen för att förstärka skillnader mellan kroppens olika vävnader. Jodkontrastmedel används varje dag i samband med vissa bestämda röntgenundersökningar. Effekten av kontrastmedel underlättar för att få en bra bilddiagnostik. Användning av kontrastmedel är inte riskfritt eftersom kontrastmedel kan orsaka negativa reaktioner som kan uppträda antingen som akuta eller sena, exempelvis hjärtstillestånd eller klåda. Syfte: Att belysa vikten av information till patienten om risker och biverkningar inför intravenös jodkontrastmedelsinjektion samt att belysa röntgensjuksköterskans roll och ansvar i samband med denna information.
