New and increased demands are being put on leaders in contemporary organizations. This is an effect of organizations’ development from centralization and hierarchy to de-centralization and increased employee-operate responsibility. Through this, leaders’ communicative mission have changed and become more difficult. With taking this de-velopment in consideration researchers are now illuminating the
In this work, surface enhanced Raman spectroscopy (SERS) was combined with dielectrophoresis (DEP) to realize a controllable in situ detection method of enhanced Raman signals from molecules in suspension environment. Polymer beads coated with gold nanoparticles were prepared as SERS ‘hot spot’ substrates. Several DEP electrode designs were evaluated and the stripe electrode succeeded in manipulat
A signal with harmonic structure is often characterized by its fundamental frequency, or pitch. This single parameter contain vital information of a range of applications such as musical transcription, tuning of stringed instruments, speech processing and more. Some signal sources, for instance a sti vibrating string, exhibit waveforms with slightly deviating harmonic structure. This phenomenon is
This thesis explores the legal, ethical, and human rights challenges posed by emerging neurotechnologies and Artificial Intelligence (AI)-driven neural implants within the European Union. It critically assesses the adequacy of current EU regulatory frameworks, specifically the General Data Protection Regulation, the Artificial Intelligence Act, and the Medical Device Regulation in addressing the u
In the conflict zone of Northern Syria, agriculture is the livelihood of a major part of the population. Nevertheless, the reasons for changes in agricultural land are manyfold. This paper looks at two areas in North Syria which have been under Syrian governance until the Syrian Civil War (2011) and were contested territory until 2016. Since then, the Rojava area has been governed by the PYD, a Ku
Varje år ges tusentals barn och unga insatser inom ramen för den svenska samhällsvården. Placeringar i bland annat familjehem, på HVB, SiS-hem eller i det egna hemmet utgör en väsentlig del av samhällets vård till denna utsatta grupp. Vid ett tvångsomhändertagande inom ramen för LVU är det socialnämnden som enligt 11 § första stycket LVU ska besluta var barnet eller den unga ska placeras. NämndensEvery year, thousands of children and young people are cared for within the Swedish social welfare system. A crucial aspect of society’s care to this vulnerable group is the possibility of carrying out placements in for example foster families (familjehem), HVB residential care homes (HVB), a SiS’s special residential homes for young people (SiS-hem), or in their own homes. When a child is taken i
Society is undergoing a great transformation with regard to the climate crisis, where electrification plays a crucial role in decarbonizing. To meet the future energy demand, improving power grid utilization is essential. This thesis develops standardized methods to evaluate and identify key parameters in terms of impact and branch loading, and to determine the probability of load flow scenarios u
Even though the relative contribution of neutralizing antibodies (Nab) to prevent progression to AIDS during HIV-1 infection is still unclear, the induction of broadly NAb directed against HIV-1 through vaccination is considered to represent an important goal for the development of HIV-1 vaccines. Factors contributing to the induction of NAb may include the strength and duration of antigenic stimu
Intensity-modulated radiation therapy (IMRT) has during the recent years become a frequently used technique in radiotherapy. Lately IMRT has also been combined with rotational beam delivery, with a simultaneously moving couch, a technique called tomotherapy. The great benefit with this treatment method is the ability to give highly conformal treatments, with high dose to the tumour, while sparing
Okawangodeltat är södra Afrikas största våtmark och en av världens minst påverkade våtmarker. Kunskapen om hur våtmarkssystemet fungerar är begränsad, särskilt vad gäller halter av näringsämnen och omsättning av näringsämnen i de dominerande våtmarksväxterna. I den här studien presenteras analyser av kol- , kväve- och kiselhalter i Cyperus papyrus som är den dominerande akvatiska växten i stora deThe Okavango Delta is southern Africa’s greatest wetland and is among one of the most pristine wetlands in the world. There is moderate information about how this system functions, however, the research on nutrient concentrations and cycles is especially limited. This study provides new knowledge on the Okavango Delta by analysing samples of Cyperus papyrus, one of the main aquatic plants in the a
This thesis covers three contributions in applications of neural networks. The first is related to diversity and ensemble learning, while the other two cover novel applications of the self-attention mechanism. An important aspect of training a neural network is the choice of objective function.

Research on floral volatiles has grown substantially in the last 20 years, which has generated insights into their diversity and prevalence. These studies have paved the way for new research that explores the evolutionary origins and ecological consequences of different types of variation in floral scent, including community-level, functional, and environmentally induced variation. However, to add
Protandry is a widespread life-history phenomenon describing how males precede females at the site or state of reproduction. In migratory birds, protandry has an important influence on individual fitness, the migratory syndrome, and phenological response to climate change. Despite its significance, accurate analyses on the dynamics of protandry using data sets collected at the breeding site, are l
The newly developed website ’Den botaniska skattkammaren’ [The botanic treasury; www.botskatt.se] is presented. It is intended to be gradually filled with miscellaneous information about vascular plant taxa found in, or expected to be found in Swedish nature (i.e. including all kinds of ephemerals and garden escapes). The material included will partly be newly produced, partly reproduced with permThe newly developed website ’Den botaniska skattkammaren’ [The botanic treasury; www.botskatt.se] is presented.
