It has repeatedly been shown that consumers consider the higher price of organic produce to be a barrier to buying organic food products. The present paper therefore asks whether organic consumption affects consumers’ actual total food expenditures. Food purchase data for a panel of Danish households during 2006–2014 were used to compare the total food expenditures of different organic household s
Artikeln behandlar utsignalåterkoppling av system där funktionen som avbildar tillstånden på mätsignarlerna har en mängdvärd invers.Vi visar att om mängden har begränsad kardinalitet, så går det att komprimera historiken till en ändlig vektor som beräknas rekursivt.Resultatet exemplifieras på diskrettidsintegratorn där mätsignalen är absolutbeloppet av tillståndet och får fram en förvånandsvärt enThis article considers output-feedback control of systems where the function mapping states to measurements has a set-valued inverse. We show that if the set has a bounded number of elements, then minimax dual control of such systems admits finite-dimensional information states. We specialize our results to a discrete-time integrator with magnitude measurements and derive a surprisingly simple sub
In the present article we explore when, where, and how Swedish sexual minority women experience minority stress and microaggression. Drawing on deductive thematic analysis of forty-eight interviews, we show that minority stress and microaggressions were experienced in a wide range of everyday life areas. Exposure was described in the forms of physical violence, threats and verbal abuse, ignorance
Recent studies of selective auditory attention have demonstrated that neural responses recorded with electroencephalogram (EEG) can be decoded to classify the attended talker in everyday multitalker cocktail-party environments. This is generally referred to as the auditory attention decoding (AAD) and could lead to a breakthrough for the next-generation of hearing aids (HAs) to have the ability to
The actor’s practice and bodily training during the twentieth century are specifically related not only to different bodily techniques, but also to language, modern society, and the concept of freedom. Nationalism, anti-intellectualism, bodily and vitalistic purism, and a sceptical distance from the modern project at the beginning of the twentieth century serve as a starting point for a discussion
I argue along the following lines: For Wollstonecraft, liberty is independence in two different spheres, one presupposing the other. On the one hand, liberty is independence in relation to others, in the sense of not being vulnerable to their whim or arbitrary will. Call this social, or political, liberty. For liberty understood in this way, infringements do not require individual instances of int
Gate arrays are often presented as a convenient means for ASIC prototyping. Obviously, they can both perform the same function and therefore be built from the same behavioral description. Design development implies a process of subsequent parameter bindings, leaving steadily less freedom for the remaining implementation choices. On the other hand, the ASIC offers more place & route freedom tha
This chapter addresses the control of glucose feeding in fed-batchreactors. The feeding strategy is based on a pulse technique, whichdoes not require a priori knowledge of the process. A feedbackalgorithm optimizes the feed rate with respect to the constraints ofaerobic conditions and overfeeding. Stability and performance analysisare performed on a simplified model of the reactor, using standard
Information literacy is both a common and an important learning activity with higher education. That said, it is under-theorized as a process and as a path to a product. In order to meet the need for theory, the four panelists will offer four distinct possibilities for theoretical frameworks. While the four frameworks are able to stand alone, there is also the likelihood that they might be melded
