Det faktum att Sverige blir allt mer internationaliserat och samhället mer mångkulturellt väckte ett intresse av att skriva om bröstarvingars arvsrätt ur ett såväl nationellt som internationellt perspektiv, där resultatet avsågs ställas i relation till svensk IP-rätt om ordre public. Idag tar alla barn lika lott enligt 2 kap. 1 § ÄB. Principen om istadarätt inträder om arvlåtarens barn avlider innan honom eller henne, då arvlåtarens barnbarn ärver istället. Bröstarvingar har alltid en rätt till hälften av sin arvslott enligt laglottsskyddet i 7 kap. 1 § ÄB. Det har diskuterats om laglotten bör bevaras i svensk arvsrätt eller om den bör avskaffas. Alla de nordiska länderna har någon form av laglottsskydd liksom de flesta europeiska länder med undantag från England och Wales, där det råder fullständig testationsfrihet. Även muslimska länder saknar motsvarighet till laglottsskydd. Det här kan väcka frågan huruvida ett land som saknar en skyddsregel som kan likställas med det svenska laglottsskyddet kan utgöra en grund som aktualiserar ordre public. I svensk rätt finns genom ordre public en möjlighet att åsidosätta en utländsk lag med hänvisning till att denna är uppenbart oförenlig med grunderna för det svenska rättssystemet. Den islamiska arvsrätten skiljer sig avsevärt mer från den svenska arvsrätten, än vad arvsrätten gör i exempelvis något västeuropeiskt land. Det kan diskuteras om någon grund i den islamiska arvsrätten för bröstarvingar kan strida mot grunderna för den svenska rättsordningen och på så vis aktualisera ordre public. Den svenska arvsrätten för bröstarvingar är till en stor del av dispositiv karaktär, varför ordre public endast kan bli aktuell i en internationell arvstvist där utländsk lag ska tillämpas. Domstolarna tenderar att tolka ordre public restriktivt, förmodligen av rädsla för att det lands lag som åsidosätts skulle kunna göra motstånd. Framtida tillämpning av ordre public kan begränsas ytterligare när EU:s arvsförordning träder i kraft. Det är fortfarande svensk domstol som har att avgöra vad som i det enskilda fallet kan bedömas vara uppenbart stridande mot grunderna för det svenska rättsystemet och vilken inverkan det kan ha på tvister som berör bröstarvingars arvsrätt. / The fact that Sweden is increasingly becoming more internationalized and developing a more multicultural society, stimulated an interest in writing about direct heirs inheritance rights from a national and international perspective, in which the outcome was intended to be set in relation to the Swedish Private International Law on public policy. Nowadays all children take equal shares according to chapter 2 paragraph 1 “Ärvdabalk”. If the deceased’s child passes away before him- or herself, the deceased’s grandchildren are entitled to inheritance through the Swedish istadarätt. The Swedish legal portion is enacted in chapter 7 paragraph 1 “Ärvdabalk” and entitles direct heirs half of his or her inheritance share. There has been discussion about whether the legal portion should be preserved or abolished in the law of Swedish inheritance. All the Nordic countries have a form of legal portion, as well as most of the European countries, apart from England and Wales, where there is a complete testamentary freedom. Even Muslim countries have no correspondence to the protection of legal portion. This may raise the question whether a country, which is lacking a protective rule that can be compared with the Swedish legal portion, may constitute a basis for public policy. According to the Swedish law there is an opportunity, through public policy, for Sweden to override a foreign law on the grounds that it is clearly incompatible with the foundations of the Swedish legal system. The Islamic inheritance law differs considerably from the Swedish inheritance law, in comparison to the right of inheritance in for example any Western European country. It is debatable whether any basis in the Islamic inheritance law of direct heirs may conflict with the fundamentals of the Swedish legal system and therefore actualize public policy. The Swedish right of inheritance for direct heirs is to a large extent of dispositive nature, which is why public policy can only become relevant in an international succession dispute, where a foreign law is applicable. The courts tend to strictly interpret public policy, probably because of the fear that the country's law, which gets overridden, could oppose. Future application of public policy may be further limited when the EU Succession Regulation enters into force. It is still up to the Swedish court to determine what in each case is deemed to be manifestly incompatible with public policy in Sweden, and what impact this may have on the succession of direct heirs.

The effect of portion size on food intake is a well-documented phenomenon: when served larger portions, individuals significantly increase their food intake. Insofar authors have limited their research on presenting the potential outcomes, while identifying several conditions favorable to this phenomenon. Indeed, the mechanisms of this effect are poorly understood and no research has insofar provided conclusive evidence regarding the underlying mechanism that could help explain the portion size effect. The first part of this dissertation aimed to fill this gap. We argue that the anchoring and adjustment heuristic accounts for most of the favoring conditions evidenced in earlier research and present it as a possible mechanism underlying the portion size effect. In this view, the portion size served is used as an anchor whereas other influences (i.e. economical, metabolic, regulatory, physiological, sensory, social and environmental) may further contribute to adjust total amount of food consumed. Moreover, we argue that prevention strategies based on this decision making literature may be similarly effective to limit excess food intake from enlarged portions. <p><p>The second and third chapter of this dissertation focus on two other factors related to the portion size of foods, namely the container size and the structure of the portion (i.e. food item size). The discussion of this dissertation reviews the facilitating conditions put forward previously to understand the portion size effect, as well as those reinforcing this effect, and how they may be integrated in an anchoring and adjustment perspective of eating. Finally, it aims to provide a food intake model that may accommodate for most environmental influences, with a special focus on the three influences mentioned above. / Doctorat en Sciences Psychologiques et de l'éducation / info:eu-repo/semantics/nonPublished
