The History of African Development aims to draw experts in the field of African History and African Development Studies together around an open access textbook for African teachers and undergraduate students. The textbook is reaching out to all African and non-African scholars willing to contribute a concise chapter (ca. 5000 words). The chapters describe and explain various aspects of historical

The hardware-attractive block cipher family KTANTAN was studied by Bogdanov and Rechberger who identified flaws in the key schedule and gave a meet-in-the-middle attack. We revisit their result before investigating how to exploit the weakest key bits. We then develop several related-key attacks, e.g., one on KTANTAN32 which finds 28 key bits in time equivalent to $2^{3.0}$ calls to the full KTANTA

A model of emotional conditioning is ex- tended with a cortical model where stimulus codes compete for activation. This system is combined with motivational inputs that mod- ulate both sensory and emotional processing. The extended model is able to reproduce the attentional blocking effect. It can also learn to switch between different sensory targets when the motivational state changes. The relat

This thesis deals with behaviours during reproduction in precocial birds, both from the perspective of the female and of the embryos. Female pheasants in good physical condition laid larger eggs and produced a higher proportion of daughters than females in poor condition. Furthermore, females mated with a male with long spurs produced a higher proportion of sons, showing that females adjusted the

Popular Abstract in Swedish Dekompressionssjuka (DCS) är ett tillstånd som kan uppkomma när man utsätts för en hastig sänkning av omgivningstrycket. Bakgrunden till tillståndet är att vävnadslagrad gas frisätts till blodbanan och där på olika sätt kan ge upphov till symptom från lätta hudbesvär till livshotande påverkan på det centrala nervsystemet. Vid atmosfärstryck är gasinnehållet i kroppens vReductions in ambient pressure liberates gas in various tissues and can result in decompression illness. In this thesis the patophysiological implications of a blood gas interface resulting from decompression was investigated with reference to the influence on biochemical mediators of inflammation. In a series of experiments, animals and human subjects have been exposed to hyperbaric trauma of dif

Purpose : This study aimed to describe the development of Arabic and Swedish lexical organisation in bilingual children with language impairment (BLI). Method : Lexical organisation was assessed through word associations in 10 BLI and 10 bilingual children with typical development (BTD), aged 6;2 – 8;0 years, matched for age and gender. The participants were assessed twice, with a 1-year interval.

Vad betyder massmedia för synen på sociala problem och socialpolitik? Författarna i denna bok tar ur olika vinklar upp massmediers betydelse när det gäller att forma allmänhetens och beslutsfattares världsbild, inte minst gäller det socialpolitiska brännande frågor som hur invandrare behandlas i press och tv eller hur man rapporterar om sociala problem som brottslighet. Men vilka är då de världsbi

This paper examines questionnaire-related issues of variations in the wording of questions and the objective accuracy of the response, in terms of three traffic-related phenomena (accident frequency, incident frequency, and speeding). ca. 900 survey respondents, living along four major arterial streets in Malmö, Sweden, estimated the occurrence of the phenomena in question. The dispatch consisted

Any perceived human activity is, by definition, also a complex informing system. Human activity systems must continually adapt to their dynamic environments in order to survive. There is therefore a role for deutero-lerning through human sense-making and multiple levels of reflection in bringing this about. In this chapter, the authors suggest a need for an approach based in philosophy as practice
