Many birds and mammals store energy as hoarded food supplies. A supply of stored food is beneficial during periods when food is scarce, but building up and managing such a supply also entails costs. The optimal number of caches will be reached when the net benefit is at its maximum. If dominants can steal more stored food from subordinates than the other way around, the optimum will differ between
Background Adolescence is characterized by large bodily changes and a heightened body-focus. It is also a sensitive period for the onset of various forms of psychopathology. Previous longitudinal studies have shown that body dissatisfaction is a predictor of disordered eating, non-suicidal self-injury (NSSI), and depression among adolescents. Body dissatisfaction, however, only represents one aspe
In this paper we give a distributed solution to the problem of making a team of non-holonomic robots achieve the same heading (attitude consensus problem) using vision sensors with limited field of view. The use of cameras with constrained field of view limits the information the robots perceive compared to other omnidirectional sensors. This makes the consensus problem more complicated, because t
Why should moral philosophers, moral psychologists, and machine ethicists care about computational complexity? Debates on whether artificial intelligence (AI) can or should be used to solve problems in ethical domains have mainly been driven by what AI can or cannot do in terms of human capacities. In this paper, we tackle the problem from the other end by exploring what kind of moral machines areWhy should moral philosophers, moral psychologists, and machine ethicists care about computational complexity?

We report metallicities for three ∼Gyr-old stars in the Milky Way nuclear star cluster (NSC) using high-resolution near-infrared spectroscopy. We derive effective temperatures from a calibration with Sc line strength, which yields results in good agreement with other methods, and metallicities from spectral fits to Fe i lines. Our derived metallicities range from −1.2 < [Fe/H] < + 0.5, a span of 1
IF steel sheets were processed by conventional symmetric and asymmetric rolling (ASR) at ambient temperature. The asymmetry was introduced in a geometric way using differential roll diameters with a number of different ratios. The material strength was measured by tensile testing and the microstructure was analyzed by optical and transmission electron microscopy as well as electron backscatter dif
In Sweden, buying sex is an illegal act that is also often viewed as immoral, which is understood in this thesis as sex buyers being stigmatized. The aim of this study was therefore to understand how Swedish men who buy sex describe themselves and how they discuss the criminal act of buying sex in an escort forum on the Internet. A qualitative method with a netnographic viewpoint was used wherein
The concept of Industry 4.0 is widely discussed among scholars and business leaders alike. Being able to adapt to this fourth industrial revolution is argued by many as necessary to stay competitive and to be profitable. Many companies today, however, have production lines built on legacy systems, as well as their own unique product challenges. This study aims to overcome these challenges by explo
We live in a world where people move in-between countries every day, every month, every year. Family, work, education, those are only some of the motivators for getting out of the comfort zone and starting a new adventure, sometimes even abroad. This dissertation investigates students and how they handle the furniture of their private living spaces during their time in academic mobility. Academic
Due to society’s modernization and climate changes, transboundary crisis is becoming more severe. This means that communication in many cases needs to be virtual, especially via radio, instead of face-to-face. At the same time, there is a willingness to co-locate in a greater extent. The aim of this paper is to increase the understanding of how the means of communication affects the outcome of a
The aim with this study was to investigate the senses of the lexemes /assassinated/, /killed/, and /murdered/ in 21st century American and British newspaper discourse, which was done with the method of corpus-driven Cognitive Linguistics. The main research questions dealt with how the combination of grammatical and contextual features of the articles frame patients and agents of the verbs. A focus
The unparalleled economic growth of China during the latter 20th century and early 21st century, has led to the country becoming a great power and perhaps on the fast track to even becoming a superpower. This growth has come mainly in the form of manufactured goods, which need vast amounts of energy and resources to produce, most important of which is oil. Today China is a net importer of oil, and
Multiculturalism theories and entrepreneurship research, in terms of personality, shows significant similarities indicating that multicultural individuals could possess essential skills to survive in entrepreneurial environments. However, these two streams of research have yet to be integrated. The aim of this research is to explore and understand how multiculturals behave in and influence their n
