This paper challenges the dominant conceptualization of authentic self-presentation as real, genuine or true expression of inner essence or social identity (Lehmann et al., 2019) and calls for its redefinition in light of the rise of AI-generated content within algorithmically mediated online environments. Authenticity has long been central to identity construction and self-presentation, tradition
Associated Trio is the newest sub-regional format of cooperation in Europe, counting only a year since its foundation in May 2021 by the three member states: Georgia, Ukraine and Moldova. It shares some similarities with the Visegrad Group, the most prominent cross-country cooperation format of the Central European states. The most important common feature of these two groups is that their member
Popular Abstract in English Insects, birds, bats and pterosaurs have all evolved the ability to fly, even though it requires a lot of energy. The advantage is obvious: one can move about vertically, to go where others cannot, find and access distant food sources or escape your predators. But flying is also a very fast mode of transportation, and when you count the amount of energy required to get Flight is an expensive form of locomotion, but also offers the ability to travel great distances at relatively low cost. Birds have developed various adaptations for optimizing flight performance. The main aim of this thesis is to identify how morphological variables in birds affect aerodynamic drag and flight performance. To this end I studied the aerodynamic performance of a jackdaw (Corvus mone
The Church has been a dominant actor in the history of care and social support, but it met several restrictions during the 20th Century. The Church of Sweden now has,since the separation from the state A.D. 2000, the possibility to act as a "welfare entrepreneur". But the willingness to do so seems limited. Even if innovative examples are seen the parishes hesitate for organisational and ideologic
Tropical forest productivity is sustained by the cycling of nutrients through decomposing organic matter. Arbuscular mycorrhizal (AM) fungi play a key role in the nutrition of tropical trees, yet there has been little experimental investigation into the role of AM fungi in nutrient cycling via decomposing organic material in tropical forests. We evaluated the responses of AM fungi in a long-term l
Agricultural intensification and the subsequent fragmentation of semi-natural habitats severely restrict pollinator and pollen movement threatening both pollinator and plant species. Linear landscape elements such as hedgerows are planted for agricultural and conservation purposes to increase the resource availability and habitat connectivity supporting populations of beneficial organisms such as
Previous studies report high and increasing iron (Fe) concentrations in boreal river mouths. This Fe has shown relatively high stability to salinity-induced aggregation in estuaries. The aim of this study was to understand how the speciation of Fe affects stability over salinity gradients. For Fe to remain in suspension interactions with organic matter (OM) are fundamental and these interactions c
The contribution of this licentiate thesis lies in the modelling of a multi-echelon inventory system with more general backorder cost structures. Backorder costs are traditionally assumed to be linear, whereas we consider structures that are more general functions of the customers’ time in backorder. The system studied is a two-echelon system with one central warehouse and a number of local sites,The contribution of this licentiate thesis lies in the modelling of a multi-echelon inventory system with more general backorder cost structures.

A central concept raised by the climate justice movement is climate debt. Here, the claims and warrants of the movement support for climate debt is identified through an argumentation analysis of their central manifestos. It is found that the climate debt claim is understood as primarily restorative, in the sense that the environmental space of the developing countries must be returned, “decoloniz

This study examines the effects on risk-minimisation by incorporating emerging market equities in a portfolio, from the perspective of a Swedish investor. Since investors usually care about returns these are also a part of the study. The hypothesis is that the international diversification benefits will outweigh the higher risks of emerging market equities. The analysis is conducted on 267 monthly
Cloud condensation nuclei (CCN) number concentrations alongside with submicrometer particle number size distributions and particle chemical composition have been measured at atmospheric observatories of the Aerosols, Clouds, and Trace gases Research InfraStructure (ACTRIS) as well as other international sites over multiple years. Here, harmonized data records from 11 observatories are summarized,
An investigation of the autonomy of the process region at the tip of a crack is carried out. An elastic plastic linearly hardening material is assumed. A cohesive zone model with constant cohesive stress is chosen. The cohesive zone length is observed to decrease with decreasing hardening rates and increasing cohesive stresses. For a cohesive stress larger than about three times the yield stress t
Widespread increases in iron (Fe) concentrations are contributing to ongoing browning of northern freshwaters, but the driver/s behind the trends are not known. Fe mobilization in soils is known to be controlled by redox conditions, pH, and DOC availability for complexation. Moreover, high sulfate concentrations have been suggested to constrain Fe in transition from soil to water, and declining su
Introduction: Obesity affects nearly 1 in 4 European adults increasing their risk for mortality and physical and psychological morbidity. Obesity is a chronic relapsing disease characterized by abnormal or excessive adiposity with risks to health. Medical nutrition therapy based on the latest scientific evidence should be offered to all Europeans living with obesity as part of obesity treatment in
