Many students who enter college are insufficiently prepared to follow a demanding college-level curriculum. Thus, higher education institutions often require low-performing students to repeat failed courses, a full term, or even a full year. This paper is the first to investigate the effects of such a “(grade) retention” policy on student performance in higher education. We study a setting where f
A novel process for the production of biodegradable lubricant-based stocks from epoxidized vegetable oil with a lower pour point via cationic ion-exchange resins as catalysts was developed. This involves two steps, first, ring-opening reactions by alcoholysis followed by esterification of the resultant hydroxy group in the first step. The ring-opening reaction of epoxidized soybean oil with differ
In 2018, an AI system named by its creator DABUS (Device for the Autonomous Bootstrapping of Unified Sentience) was credited by its creator to have independently invented a neural flame and a fractal container. According to its creator, DABUS is a ‘sentient artificial general intelligence can replicate all aspects of human cognition, including perception, creativity, consciousness, and sentience’
To halt the loss of biodiversity and ecosystem services, various actors including companies need to engage, but it is not yet clear what drives voluntary business commitments. We explore leverage points that might increase corporate action for conservation. We apply a structural equation model based on the theory of planned behaviour to analyse data from 618 German companies, collected through an
The aim of this study was to investigate the possibility to produce novel powder materials based on chemically modified starch granule stabilized Pickering oil-in-water (O/W) emulsions. This study also investigated the effect of partial starch gelatinization in situ, dispersed phase type (two oil types with different melting points), freezing method and thawing, and freeze-drying and rehydrating o
Given a discrete dynamical system T, one can ask what the time average of the system will be, that is, what is the average position of T^n(x) for large n? Birkhoff’s ergodic theorem, one of the most important results in ergodic theory, says that for an ergodic system on a finite measure space, the time average will in the limit as n -> infinity be equal to the space average for almost all initial
The purpose with this case study was to see if the teaching element in the teachable agent Betty increases the understanding for the students. To do this I let one group of students learn by creating a dynamic model of the content and one group learn by teaching the computer agent Betty. To measure the knowledge of the students I had a pre- and posttest. The results from the tests showed that bot
The book looks at corporate voluntarism from a socio-legal perspective and places CSR in a regulatory context. The responsible practices of leading businesses have a role in the rule-making process by clarifying general, flexible concepts such as ‘due diligence’, ‘reasonability’, ‘foreseeability’ which all have a bearing on findings of corporate ‘negligence’. Procedural regulations seeking to enco

Sets are often taken to be collections, or at least akin to them. In contrast, this paper argues that. although we cannot be sure what sets are (and the question, perhaps, does not even make sense), what we can be entirely sure of is that they are not collections of any kind. The central argument will be that being an element of a set and being a member in a collection are governed by quite differ
In this work, lipid nanoparticles were used as pseudostationary phase, PSP, for protein separation in capillary electrochromatography, CEC. The aim of the work was to use a new analytical separation technique for future analysis of protein drugs by using lipid nanoparticles as a pseudo-stationary phase with conventional UV-detection. PSP-CEC was combined with UV-detection to study proteins elution
In this thesis, it is investigated whether Per Albin Hansson and Jimmie Åkesson's concepts of “Folkhemmet” (Peoples Home) are comparable. This is done with a method that combines idea analysis and concept analysis. In concrete terms, this analysis is done in two ways. First with the help of specific analysis tools, which when applied to the selected material highlight interesting aspects. Then
