When a victim is in need, people are less likely to help when there are other persons present. In general, this means that the probability of helping decreases in negative correlation to the number of bystanders affected. In social psychology literature, researchers refer to this phenomenon as the individual Bystander Effect. From another perspective, the decreased probability for the victim to re
We live in a busy world, where the demand of ready-to-eat (RTE) salad products has increased rapidly in a relatively short time. Despite of being an easy and fast way to add more vegetables to the daily diet, RTE salads have a serious underlying risk and the amount of vegetable-derived foodborne disease outbreaks has been increasing. The aim of the present study is to protect plants against contam
Recognising the macroeconomic importance of private consumption, this thesis aims at examining possible forces that drive changes the level of households’ consumption. I do so by analysing the relationship of housing wealth, financial wealth, and consumption of households in Sweden in the short and long run. Using an M-TAR approach I find evidence for cointegration of these variables. Housing weal
I evaluate a total of 204 U.S. equity mutual funds split into one major group and one additional group for the time period 2002-2016. The major group consists of the ten largest U.S. mutual fund families based on AUM while the additional group consists of a sample of the remaining operative U.S. mutual fund families. The major group manages 58% of U.S. mutual fund supply, thus indicating a non-com
This thesis analyses price relations in Malaysian energy and agricultural markets. In partic- ular interactions among prices for biodiesel, palm oil and crude oil were studied. The levels of the series are modeled by a standard vector autoregression set-up in combination with an impulse response analysis. A multivariate GARCH was utilized for identifying possible correlations among the volatilitie
This study attempts to highlight the importance of friendship in young adulthood, motivated by a curiosity of a lack of sociological attention. This is done by exploring concepts of modernity including individualism and the formation of identity. Objective: The research attempts the answer the questions: 1) how can the importance of friendship in young adulthood be understood, 2) how is the emotio
Metropolitan cities are increasingly becoming the undisputed centers of growth and innovation. This thesis investigates the driving forces of urban growth and innovation in the Swedish metropolitan cities from the 1980’s and onwards through a mixed method case study. The theories of Richard Florida, Enrico Moretti and Edward Glaeser are used to form three hypotheses of how cities attract high-skil
This thesis explores the links between China’s demand for foreign exchange reserves and the political economy aspects of China’s monetary policy framework since the start of reforms in 1978. In a single-country approach focused on China, this study combines an assessment of the politico-economic factors that may have influenced China’s demand for foreign exchange reserves with a cointegration anal
The purpose of the thesis relates to the Quality anomaly observed in the US equity market, where stocks with Quality characteristics tend to outperform and have higher risk adjusted returns. By dissecting the Quality anomaly, the thesis aims to analyze the drivers of the over performance of Quality and investigate the presence of a systematic Quality premium. From previous research, three areas ha
Vi bor i Vintergatan, en av Universums många galaxer. Men hur bildades den, och alla andra galaxer vi kan se genom våra teleskop? Rådande teorier hävdar att för många miljarder år sedan, när Universum var ungt, bildades först små dvärggalaxer, som sedan slogs ihop till att bilda stora galaxer såsom Vintergatan. Men många detaljer i den här processen är fortfarande oklara. Därför vill vi titta på sIn this project aperture photometry has been performed for stars in the direction of the dwarf spheroidal galaxy Leo II. The observations were carried out using the Stro ̈mgren filters v, b and y, during three consecutive nights in 2003, out of which all but the first one turned out to be non-photometric. The data was reduced and calibrated (using the metallicity calibration of Calamida et al. (20
This thesis takes its outset in the newly coined expression ‘Hell Joseon’ used by the youth in South Korea. ‘Hell Joseon’ is a comparison between today’s society and the pre-modern Joseon Dynasty. By asking “what are the main characteristics of life in ‘Hell Joseon’ from a youth perspective?”, I arrive at the following conclusion. Life in ‘Hell Joseon’ is highly characterized by discrepancies betw
En människa exponeras och angrips varje dag av virus och bakterier och immunförsvaret skyddar oss från dessa angrepp. Immunförsvaret utgörs av vita blodkroppar som bildas i benmärgen och sprids vidare ut i kroppen. De vita blodkropparna finns i många olika varianter och varje variant har en specifik uppgift. Lymfocyter är en typ av vita blodkroppar och kan dela in i två huvudgrupper: Blymfocyter oToday antibodies are an important part in the treatment of diseases such as cancer and Guillain–Barré syndrome. It is of course important to be able to regulate the levels of the antibodies in the treatment. In this study a general method for antibody production were investigated. The antibody construct was made for transportation out of the cell. Four different tagged variants of an antibody wer
In today’s society, traffic congestion is a major problem in several aspects. Apart from the obvious problem that people are losing valuable time due to the resulting delays, it also has negative impact on as well the economy as the local and global environment. With the development of sensors and navigation support, it has now become possible and thus of interest to study optimal routing of vehic
Bakgrund: sjukvården genomgår ett paradigmskifte där dagens sjukvårdsinrättningar har svårt att möta patienternas komplexa behov. Nya riktlinjer ska hjälpa till att stärka bevisen för evidensbaserad design (EBD) och mycket tyder för att enbart enkelsalar bör rekommenderas. Trots detta saknas omvårdnadsforskning inom området utifrån ett patientperspektiv. Syfte: studiens syfte var att undersöka pat
Autenticitet är ett begrepp som genomsyrar nutida musikvetenskap. Begreppet har flera innebörder. Denna kandidatuppsats använder autenticitet i betydelsen tidstrogenhet eller s.k. ljudande autenticitet. Arbetet är en studie av tradjazzfestivalen i Hällevik 2016 där sju orkestrar, enligt festivalprogrammet, har ambitionen att spela jazz så som man gjorde kring 1920 i USA. Uppsatsen besvarar frågan Authenticity is a concept that permeates contemporary musicology. The term has several meanings. In this bachelor thesis authenticity means fidelity to the time period or so-called sounding authenticity. The work is a study of the traditional jazz festival in Hällevik 2016 where seven bands, according to the festival programme, play jazz as it was played around the 1920’s in the US. The essay answ
Corruption is often compared to a double-edged sword. While acting as a “necessary evil” to avoid bureaucratic inefficiencies such as red tape to grease the wheels of commerce, there are many other studies expressing their concerns regarding the negative effects corruption has on growth. Based on previous empirical evidence and theories such as the “rent-seeking” theory that conceptualize the rela
Marknaden för brobyggnad i Sverige är idag så god att företagen tvingas tacka nej till förfrågningar på grund av tidsbrist. Det är svårt att rekrytera nya konsulter eftersom det råder brist på arbetskraft med rätt kompetens, för att undvika att tacka nej till arbete är en potentiell lösning på tidsbristen att effektivisera arbetet. I samarbete med Skanska Tekniks brogrupp i Malmö utreder därför deThe bridge construction industry in Sweden is prospering. The situation is such that companies are forced to decline work due to lack of time. In addition, the recruitment of new consultants has been difficult owing to a shortage of labour with the right competency. To avoid the situation where companies are forced to decline new projects due to lack of resources, focus should be on improving the
Naturvårdsverket uppger att antalet potentiellt och bekräftat förorenade områden i Sverige under 2016 uppgick till 85 000. Siffran visar på att problemet med kontaminerad mark är tämligen omfattande. En grundsten i den svenska miljörätten är principen om att förorenaren, i detta fall verksamhetsutövaren, betalar. Vad händer om den som orsakat en föroreningsskada inte finns tillgänglig och kan stäl
Aktivering av arbetslösa har diskuterats brett inom såväl akademin som politiken under de senaste decennierna. Fokus har ofta varit på förändrade kontraktsrelationer mellan arbetslösa och samhället där rättigheter kontra krav på motprestationer har varit i fokus. Tidigare forskning kring erfarenheter av arbetslöshet har ofta framhävt dess negativa aspekter av stigmatisering, skam och social exklud
