In this article the authors reflect upon and critically examine signs of a contradiction in higher education which they discuss in terms of the tension between 'use value' and 'exchange value'. Use value here represents learning as something valuable ‘in itself’ whereas exchange value represents learning as an achievement of grades and credits to be ‘traded’ on a market. Their aim in this article

Popular Abstract in Swedish Stjärnhimlen har genom tiderna fascinerat människan och man har under historiens gång upprepade gånger försökt förklara vad stjärnorna består av samt hur de skapats. Många av dessa förklaringar har varit fantasifulla, men så här i efterhand sett ganska orealistiska. Till exempel var den medeltida bilden av stjärnhimlen att denna utgjordes av en sfär som roterade kring jThe relationship between the HgMn and Am classes of chemically peculiar stars has been investigated primarily by observing abundances of heavy elements, including Pr, Nd, Hg, Tl and Bi. The main objective of the investigation has been to gather observational evidence to provide a better understanding of the mechanisms producing the abundance anomalies of these stars, and to establish the relations

Det här kapitlet diskuterar och analyserar digitaliseringen av det vetenskapliga publiceringssystemet, framförallt i relation till peer review-processen och Open Access (OA). I vilken utsträckning är exempelvis tillit till vetenskaplig forskning, uttryckt i publikationer, rättfärdigat och hur kan den bedömas? Kapitlet använder sig av exemplet där vetenskapsjournalisten John Bohannon avslöjade bris

Some colours might have different connotations depending on people’s cultural backgrounds. When talking about evacuation, the colour employed for exit signs and flashing lights plays a significant role because it is responsible for conveying a message to the evacuees, either danger or safety. The aims of this study are to evaluate the influence of red and green emergency way-finding systems on the

Popular Abstract in Swedish Värmestrålning är högst relevant i förbränningsmiljöer. I dessa miljöer är förbränningsgaser och partiklar den huvudsakliga källan till värmestrålning. Förbränningsmiljön är komplex att beskriva. Analys av turbulenta flöden, kemiska reaktioner och transport av energi måste göras för att fullständigt beskriva miljön. Att kunna beskriva dessa fenomen är en viktig del i föThermal radiation is an important physical phenomenon in combustion environments. For the understanding of existing- and the design of new combustion environments computational modelling is a useful tool as it can describe the different transport phenomena. This thesis has focused on studying thermal radiative property models of the participating media, gases and particles. Two specific combustion

The paper deals with the problem of finding suboptimal routing paths in multi-domain Internet environment. The proposed solution can be used in traffic enginering with MPLS.

Design starts with a cognitive model and ends with a solution worked out in a way that fits into the human context of meaning which is socially decided. The bridge between the cognitive model and the final system, or thing, is a proper description that has to be possible to socially communicate. The necessary description part leads to the understanding that design, like sciences, is a kind of lear

In the software industry, there is a strong shift from traditional phase-based development towards agile methods and practices. This paper reports on a case study aimed at investigating if, and how, agile Requirements Engineering (RE) can remedy the challenges of traditional RE, and what new challenges agile RE may pose. The results from an initial case study with 9 practitioners from a large soft

Nanosized soot particles are a serious health hazard in urban air. Upon inhalation they can penetrate deep into the lungs and their fat solubility makes possible their accumulation in other organs such as the brain. For this reason legislation has continuously reduced the allowable emission levels and raised requirements for reporting the status of the exhaust system (OBD, on board diagnostics) in
