To control flight, insects rely on the pattern of visual motion generated on the retina as they move through the environment. When light levels fall, vision becomes less reliable and flight control thus becomes more challenging. Here, we investigated the effect of light intensity on flight control by filming the trajectories of free-flying bumblebees (Bombus terrestris, Linnaeus, 1758) in an exper

We draw from ongoing empirical research on the evolution of community currencies in Kenya, to analyse ways through which beneficiaries of cash transfers mediated by a community cryptocurrency – Sarafu – appropriate power and assert agency to obtain optimum financial benefits of the development intervention. We found that beneficiaries of the intervention have developed a dee

Understanding consciousness is central to understanding human nature. We have competing theories of consciousness. In interdisciplinary consciousness studies most believe that consciousness can be naturalized (i.e., consciousness depends in some substantial way on processes in — or states of — the brain). For roughly two decades, proponents of almost every theory have focused on collecting empiric

We summarise our work on male mating behaviour in the tropical butterfly Bicyclus anynana, responding to the commentary provided by Nieberding and Holveck. We acknowledge that our laboratory studies are not free of shortcomings and potential caveats, though we attempted to address or highlight these within each paper. The concerns raised seem to stem mainly from different notions with respect to t

We examine the change in status of three Swedish colleges to universities in 1999. This change greatly expanded the inflow of resources in the form of basic funding to the new universities. Using detailed individual data, we follow the careers of staff employed before 1999 at the treated institutions, examining their scientific performance, promotion, affiliation, and coauthorship behavior after t

Interleukin-1 (IL-1)-family cytokines are potent modulators of inflammation, coordinating a vast array of immunological responses across innate and adaptive immune systems. Dysregulated IL-1-family cytokine signaling, however, is involved in a multitude of adverse health effects, such as chronic inflammatory conditions, autoimmune diseases, and cancer. Within the IL-1 family of cytokines, six—IL-1

Social media is abound with women writing about consumption goods and practices associated with femininity and heterosexual nuclear family life, such as being married, dressing, cooking and home decoration. This article examines how the housewife ideal can be an attractive identity in the 2010s and, drawing on the post-humanist performativity by Karen Barad (2007), it maps the material-discursive

The complex nature of climate change requires action at different scales and in different ways, but questions remain around how to produce climate action that is both multi-scalar and joined up. Here we explore this question by adopting a relational approach to studying climate action by faith-based actors, who increasingly play an active role campaigning on climate action. Drawing on qualitative

Contemporary society operates beyond safe boundaries of the Earth system. Returning to a safe operating space for humanity within Earth system boundaries is a question of justice. The relevance of the economy—and thus of business—for bringing society back to a safe and just operating space highlights the importance of business ethics research for understanding the role of business in Earth system

Variation in mutation rates at sites in proteins can largely be understood by the constraint that proteins must fold into stable structures. Models that calculate site-specific rates based on protein structure and a thermodynamic stability model have shown a significant but modest ability to predict empirical site-specific rates calculated from sequence. Models that use detailed atomistic models o

Functional data analysis is typically performed in two steps: first, functionally representing discrete observations, and then applying functional methods to the so-represented data. The initial choice of a functional representation may have a significant impact on the second phase of the analysis, as shown in recent research, where data-driven spline bases outperformed the predefined rigid choice

Drosophila melanogaster structures its optic flow during flight by interspersing translational movements with abrupt body rotations. Whether these "body saccades" are accompanied by steering movements of the head is a matter of debate. By tracking single flies moving freely in an arena, we now discovered that walking Drosophila also perform saccades. Movement analysis revealed that the flies separ

We address the non-convex optimisation problem of finding a sparse matrix on the Stiefel manifold (matrices with mutually orthogonal columns of unit length) that maximises (or minimises) a quadratic objective function. Optimisation problems on the Stiefel manifold occur for example in spectral relaxations of various combinatorial problems, such as graph matching, clustering, or permutation synchro

Denna text är avsedd som en kort introduktion till det rättsliga området skydd av personuppgifter. Texten tar upp vissa återkommande intressekonflikter och svårigheter för ämnet genom historiska exempel samt en kort blick på debatten om ämnet under den senare hälften av 1900-talet i Sverige. Under återskildringen av den svenska debatten uppmärksammas hur datorisering gjort insamling av personuppgiThis text is intended as a short introduction to the legal field of protection of personal data. The text takes up some recurring conflicts and difficulties of the subject through historical examples and a brief glance at the debate on the subject in the latter half of the 1900s in Sweden. During the examination of the Swedish debate, it's highlighted how computerization made the collection of

Mot bakgrund av att det inte ännu finns någon fungerande gemensam valuta inom EU kvarstår valutakursrisker som ett hinder för handel inom den inre marknaden. Dessa hinder har bland andra EUD angripit med stöd av fördragsfriheterna. I uppsatsen behandlas inledningsvis frågan om användandet av utländsk valuta kan utgöra det gränsöverskridande moment som gör EU-rätten tillämplig och därefter hur den Since there still is no common currency within the EU, exchange rates still risk acting as an obstacle for trade on the internal market. Amongst others, the CJEU has addressed these obstacles through an application of the four freedoms. The initial question treated in this thesis is if the use of foreign currency is a cross-border element enabling the application of EU law, and if so, how is the c
