In recognition that the world is moving towards a new climate change regime that in many ways will be very different from the world in which the Kyoto Protocol has been operating, climate negotiators and other specialists have begun to focus their attention on developing a “framework for variable approaches” (FVA). It is hoped that this new framework will prove more adaptable to national circumstances and more capable of catalysing new ideas, at the regional, national or sub-national level. This paper examines the assumptions, objectives, scope, components and functions of an FVA, with a view to creating the right conditions in which a well-functioning global carbon market can emerge.

This article looks at an important but neglected aspect of medieval sovereign debt, namely ‘accounts payable’ owed by the Crown to merchants and employees. It focuses on the unusually well-documented relationship between Henry III, King of England between 1216 and 1272, and Flemish merchants from the towns of Douai and Ypres, who provided cloth on credit to the royal wardrobe. From the surviving royal documents, we reconstruct the credit advanced to the royal wardrobe by the merchants of Ypres and Douai for each year between 1247 and 1270, together with the king's repayment history. The interactions between the king and the merchants are then analysed. The insights from this analysis are applied to the historical data to explain the trading decisions made by the merchants during this period, as well as why the strategies of the Yprois sometimes differed from those of the Douaissiens.

The study is based on 141 pregnant Bos indicus cows, from days 20 to 70 post-insemination. First, special attention was given to the macroscopically observable phenomena of attachment of the conceptus to the uterus, i.e. the implantation, from about days 20 to 30 post-insemination up to day 70, and placentome development by growth, vascularization and increase in the number of cotyledons opposite to the endometrial caruncles. Secondly, as for the conceptuses, semiquantitative, statistical analyses were performed of the lengths of chorio-allantois, amnion and yolk sac; and the different parts of the centre and two extremes of the yolk sacs were also analysed. Thirdly, the embryos/foetuses corresponding to their membranes were measured by their greatest length and by weight, and described by the appearance of external developmental phenomena during the investigated period like neurulation, somites, branchial arcs, brain vesicles, limb buds, C-form, pigmented eye and facial grooves. In conclusion, all the data collected in this study from days 20 to 70 of bovine pregnancy were compared extensively with corresponding data of the literature. This resulted in an `embryo/foetal age-scale`, which has extended the data in the literature by covering the first 8 to 70 days of pregnancy. This age-scale of early bovine intrauterine development provides model for studies, even when using slaughtered cows without distinct knowledge of insemination or fertilization time, through macroscopic techniques. This distinctly facilitates research into the cow, which is now being widely used as `an experimental animal` for testing new techniques of reproduction like in vitro fertilization, embryo transfer and cloning.

Det tobakspreventiva arbetet är en av samhällets största utmaningar.Syftet med studien var att beskriva tobaksbruket och dess förändring över tid (1983-2003) iett slumpmässigt urval av individer 15-70 år i Jönköpings kommun. Den specifikamålsättningen var att analysera tobaksvanorna i relation till socioekonomiska förhållanden,personlighet, tandvård och tandvårdsvanor. Studien utgjordes av tre epidemiologiskatvärsnittsstudier utförda åren 1983, 1993 och 2003. En klinisk och röntgenologiskundersökning utfördes av mun och tänder. Individerna fick även besvara ett frågeformulär.Resultaten visade en statistiskt signifikant minskning av tobaksbruket från 31 %tobaksbrukare 1983 till 24 % såväl 1993 som 2003. Detta gällde samtliga åldersgrupper utomåldersgruppen 40-åringar. I första hand minskade andelen rökare. Samtidigt ökade snusarna isamtliga åldersgrupper 20-60 år innebärande ett i stort sett oförändrat tobaksbruk 1993 och2003. Det förelåg ingen statistisk signifikant skillnad vid de tre undersökningsåren mellantobaksbrukare och icke/brukare med avseende på inkomst-, utbildningsnivå, civilstånd, ochKASAM poäng. År 2003 förelåg en statistisk signifikant skillnad mellan brukare och ickebrukare med avseende på frekvens av tandvårdsbesök, där tobaksbrukarna i störreutsträckning än icke brukaren, inte besökte tandvården eller besökte tandvården oregelbundet.Icke brukarna borstade tänderna statistiskt signifikant oftare än tobaksbrukarna år 1993 ochicke brukarna använde tandstickor statistiskt signifikant oftare än tobaksbrukarna år 1983 och2003.
