In 2002 the Budapest Open Access Initiative was born, and shortly thereafter in 2003 the Bethesda Statement and the Berlin Declaration followed suit. These three initiatives are frequently viewed as the ground staples of the Open Access movement, and promoted free access to academic journals for everyone with an internet connection. These three initiatives has been studied in this essay, as well a
This essay introduces the sequential Good-Turing estimator and reviews the Good-Turing, Good-Toulmin and smoothed Good-Toulmin estimators. Some theoretical properties and drawbacks of the estimators are described. MonteCarlo simulation is then used to compare the performance of the sequential Good-Turing estimator to the performance of the Good-Toulmin estimator along with the smoothed Good-Toulmi
Bioprinting is the act of using a 3D-printer in order to make structures out of materials that contain living cells. A big problem with this is that there is no defined standard for how this bioink should be made or what characteristics it should possess. This report intends to establish a set of criterias with which to evaluate the quality of the hydrogel used to create a bioink. This project wil

This thesis examines sexual violence at festivals based on eleven interviews with people that have been to two popular festivals in Iceland, Eistnaflug, and Þjóðhátíð. The thesis seeks answers to three research questions; How are festivals characterized by festival attendees? How do festival attendees explain sexual violence at festivals? What preventive methods at festivals have festival attendee
Förintelsen är ett skrämmande exempel på vad som kan ske när man inte erkänner människors lika värde. Romerna, jämte judarna, var grupper som utsattes för nazisternas systematiska förföljelse på rasmässiga grunder. Trots en traumatisk historia fortsätter Förintelsen av romer att hamna i utkanten av minnespolitiken. Syftet med denna uppsats är att undersöka och analysera närvaron, bristen eller fråThe Holocaust is a frightening example of what can happen when one does not recognize the equal value of human beings. The Romani people, along the Jews, were groups that were exposed to systematic persecution on racial grounds by the Nazi regime. Despite a traumatic history, the Holocaust of Roma continues to end up on the outskirts. The objective of this paper, “To be realised to the extent one
The possibility of being able to examine the inside of the human body is the foundation of today’s medical diagnostics. This can be done through different imaging systems, where ultrasound is one of the most important imaging methods used. Ultrasound does not endanger the patient during examination, unlike other imaging systems that use ionizing radiation or strong magnetic fields. In order to obt
In this study, the quantitative relationship between the three dimensions of transformative capacity – cognitive, structural and agency – and the climate change performance of countries is examined. To do this, indexes are created and panel data regressions conducted. The result indicates a significant negative relationship between the cognitive and diversity dimension index and climate change per
Låga relativa fuktigheter inomhus orsakar negativa hälsoeffekter på människor. Vanligast uppkommer torrhetssymptom i ögon, näsa, hals och hud. Aktiv befuktning genom ventilationen i torra klimat kan vara en åtgärd, dock måste det analyseras ifall den extra fuktproduktionen kan orsaka fuktskador. Syftet med examensarbetet är att studera hur ytterväggen i ett kontor påverkas av en förhöjd relativ Low levels of relative humidity indoor has a negative effect on the health of people. Most commonly appears dryness symptoms in eyes, nose, throat, and skin. Humidification of the air through ventilation in dry environments could be a solution, though it must be analyzed if the extra moisture can cause any problems. The purpose is to study how the outer wall in the building will react to the ele
Människor spenderar en betydande del av sitt liv i arbete. I relation till detta är arbetstillfredsställelse viktigt för anställda och organisationer. Denna studie ämnade undersöka hur personlighet och relationen till ledare predicerar arbetstillfredsställelse. Personlighet mättes utifrån teorin om de fem personlighetsfaktorerna (Big Five), medan relation till ledare mättes genom Leader-member excPeople spend a substantial amount of their life at work. In relation to this job satisfaction is important for employees and organizations. The study’s aim was to examine if employee’s job satisfaction is predicted by personality and relationship to one’s leader. Personality was measured through the theory of five personality factors (Big Five), whilst relationship to one’s leader was measured thr
I och med digitaliseringen har möjligheterna att möta och kommunicera med likasinnade individer underlättats avsevärt. Digitala miljöer, såsom incelforum och radikalnationalistiska forum, har under senare år uppmärksammats på grund av deras koppling till olika våldsdåd. Forskning har tidigare pekat på att det finns en del paralleller mellan incelkulturen och den radikalnationalistiska kulturen, me

Ferroelektricitet upptäcktes först 1921 av professorn Joseph Valasek i kaliumnatriumtartrat, ett ämne som är mer känt som "Rochelle salt". Valasek beskrev likheten mellan ferroelektricitet och det redan då väl beskrivna ferromagnetismen. Likt ferromagnetiska material och deras permanenta magnetiska poler uppvisar ferroelektiska material en permanent elektrisk polarisation, en separation The ferroelectric tunnel junction FTJ is a rather old concept but has recently been in the spotlight for its promising properties in computer memory technology and neuromorphic computing. The device consists of a ferroelectric insulator sandwiched between two electrodes, and by polarisation switching the resistance along the heterostructure can drastically be adjusted. The optimisation possibili
Parallellt med ett idag ständigt växande bostadsprekariat är samtalet om en samlad social bostadspolitik inom riksdagen frånvarande. Utanför parlamentet, däremot, vardar en ny bostadsrörelse. Med utgångspunkt i en underliggande jämförelse med den socialdemokratiska folkrörelsen ämnar uppsatsen studera vilka förutsättningar denna bostadsrörelse har att få politiskt inflytande. Via semistrukturerade
‘Killer acquisitions’ are fairly a new phenomenon which stems from a researcher’s study related to concerns from a series of mergers in the pharmaceutical industry (Big Pharma) around 2018. Killer acquisitions occur in the pharmaceutical sector and also in large digital and technological markets occupied by large companies (Big Tech). They are putting themselves into a position of overwhelming mar
Several studies have shown psychological safety to be one of the leading factors in creating an effective team. Nevertheless, there is very little academic research studying the challenges that appear in a hybrid work environment or which practices in fostering psychological safety may need to be adapted to create an effective team in such a work environment. With the growing trend of the hybrid w
För att möjliggöra omställningen från fossila kolväten har bioolja identifierats som ett viktigt verktyg. Bioolja refererar till ämnen med liknande egenskaper som traditionellt petroleum, men som produceras genom kontrollerad förbränning (pyrolys) av jord- och skogsbruksavfall. Bioolja har stor potential, eftersom dess kemisk-fysikaliska likhet till de fossila kolväten som redan används som bränslAn important stepping stone in transitioning from a fossil-fuel based transportation system is the production of bio-fuels such as bio-oils. For bio-oils to be commercially viable, catalytic upgrading via hydrodeoxygenation is required, typically using Ni-Mo oxide or sulfide catalysts. To optimise such processes, a thorough understanding of the catalyst is required. Spark discharge generation (SDG
The purpose of this master’s thesis is to illuminate the information practices of professional musicians in the field of Early music. These musicians have a special interest in exploring the performance practices of the time periods when the music was composed, to make it more vivid in the present. This more and more widespread approach to Early music is called Historically Informed Performance (H
As technology advances and traditional ways of entertainment now can be found in the palm of one’s hand, the consumer expectations are higher than ever. This has created a greater demand by airline passengers for varied entertainment options on their flights. To keep up with the current demands, the development process aims to create an enticing multiplayer experience for passengers on short-haul
Världen står inför stora utmaningar när det gäller miljö- och klimatförändringar. För att bemöta detta finns svensk och internationell miljölagstiftning och hållbarhetsmål. I detta ingår regleringar och förslag till åtgärder gällande avfallshantering och hantering av naturresurser. Byggbranschen är den sektor som genererar störst mängd avfall i Sverige, en stor del av detta består av schaktmassor.The world is facing challenges when it comes to environmental and climate changes. To address this Swedish and international environmental legislation and sustainability goals have been developed. In these measures management of waste and natural resources are included. The construction industry is the sector that generates the largest amount of waste in Sweden. When excavating there is usually ex
