The study, also known as The Research Bay, due to that it was conducted in collaboration with the infamous BitTorrent site The Pirate Bay, by the Cybernorms research group. The aim of the online study of The Pirate Bay community has been to des
Many factors influence the language environment in preschool, for example, the language background and competence of the teachers, children's ages, language proficiency levels and language backgrounds, the access to play and learning materials and the composition of preschool groups. There is a lack of knowledge on how various aspects of the interactive language environment in preschool relate to
We report on the commissioning of an ultrafast timing diagnostic for measuring a time-offset signal between two different synchronized ultrashort light pulses. The method is based on sum-frequency generation in a nonlinear crystal. The setup is similar to an auto/cross-correlator setup. In this case, one of the beams is a relatively weak diagnostic beam of visible light from a bending magnet at Fe
We employ a qualitative approach to explore whether and how the use of performance measurement systems differs between public and private providers in Swedish and Finnish primary care, from the perspective of primary care centre managers. The two settings are similar in terms of decentralised healthcare systems but differ in terms of organisation of primary care and governance principles for publi
The implementation of low-carbon futures requires both the assembling of new technologies, and practices, as well as the ‘unmaking’ of extant high-carbon infrastructures. Here, we bring together geographical, STS, anthropological, and sociological thinking on time to re-conceptualise such processes of unmaking. We argue that a focus on temporalities is especially pertinent to the unmaking of mater
In the pursuit of CO₂-neutral renewable energy solutions, biofuels have emerged as one of the key strategies. However, biodiesel production generates a surplus of crude glycerol (GL), creating a need for efficient valorization pathways. The conversion of GL into value-added chemicals represents a sustainable approach to address this issue. Metal nanoclusters (NCats) embedded within metal-organic f
Before performing 177Lu-DOTATATE therapy for neuroendocrine tumors, somatostatin receptor (SSTR) PET imaging is currently used to confirm sufficient tumor SSTR expression, but it also has potential to be used to personalize treatment by predicting absorbed doses to critical organs. This study aims to validate the predictive capability of SSTR PET in anticipating renal absorbed dose in the first cy
Debts among individuals and households in Sweden have increased over the years. Although statistics from the Swedish Enforcement Authority show that the total number of people registered with excessive debts has declined for the third year in a row, the total amount of debt of those individuals and households who are already overindebted on other hand continues to increase. Moreover, debtors regis
The aim of this study was to describe and analyze the social workers’ experiences of the organizational change in social service caused by the outbreak of the Covid-19 virus. This has in turn created a stressful and a demanding environment for the social workers. Thus, it is of highly importance to examine the social workers’ reactions and experiences to this change. The study has done so by mainl
With low cost and high efficiency, use of airborne infrared thermography imaging from an unmanned aerial vehicle (UAV) has become a widely used technique to measure plant water stress. With that, the use of UAV mounted thermal camera as a precision agriculture technique to map crop water stress is not trivial and its success is depended on variety of factors which are still needed to be studied an
This thesis was conducted to quantitatively describe environmental and economic benefits from reuse of office furniture together with a status analysis of methods used to calculate that kind of data. Information was gathered from literature and interviews with industry players. The results from the different sources were initially presented separately and later compiled to demonstrate what they in

De Jure Belli ac Pacis Libris Tres, av Hugo Grotius, och den westfaliska freden, i 1600-talets Europa, har ofta betonats av forskare som födelseplatsen för den moderna folkrätten. Denna studie har ämnat granska validiteten i dessa påståenden genom en rättshistorisk undersökning av omständigheterna kring texterna och en komparativ utredning dem emellan. Arbetets huvudsakliga syfte har varit att utfDe Jure Belli ac Pacis Libris Tres, by Hugo Grotius, and the Peace of Westphalia, in 17th century Europe, has often been highlighted as the birthplace of modern public international law. This study aims to review the validity of such statements through research of the legal history concerning the topic and through a comparative examination of the two works. The main purpose of the study have been
The cell phone industry is one of the most linear sectors, which means high resource consumption in the production of telephones and difficulties in repair. In addition, only 10-12% take-back of used units takes place, the rest are often forgotten in drawers or handled incorrectly. An interesting area of research is how companies can make their choices to reduce the life cycle environmental impact

Den termiska klimatupplevelsen påverkas mest av lufttemperaturen som är enkel att mäta med en vanlig termometer, men för att ta reda på hur temperaturen i ett rum upplevs räcker det inte med att enbart undersöka lufttemperaturen. Även om lufttemperaturen ligger på en komfortabel nivå så kan en kall yta i närheten få personen att känna att det är kyligt i rummet och på motsvarande sätt kan varma ytThe thermal climate experience is most affected by air temperature that is easy to measure with a standard thermometer, but to find out how the temperature in a room is felt it is not enough to merely examine the air temperature. Even if the air temperature is at a comforta-ble level, then a cold surface near get the person to feel that it is chilly in the room and cor-respondingly the hot surface
This report summarizes the advantages and disadvantages of organic and conventional farming from an environmental and sustainable perspective. A sustainable agriculture system needs to be able to meet a higher demand for food due to a growing population and minimize the damage of the environment at the same time. The main critic to the organic farming system is that it produces lower yields than
The field of child welfare could be considered one of the most complex social systems to work within. Whether punishing for errors or satisficing calls for accountability with firing employees and pointing to individuals as the root causes of bad outcomes, the current practice in child welfare is to utilize backward looking accountability. It is argued here that child welfare agencies would benefi
