Att dikta för livet, döden och evigheten : Tillfällesdiktning under tidigmodern tid
- 2020
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- Boken Att dikta för livet, döden och evigheten har fokus på perioden 1500 till 1800 och på svensk tillfällesdiktning insatt i sitt nordeuropeiska sammanhang. Fältet är representativt och omfattande. Vi har lyckats intressera forskare inte bara från Sverige utan även från Danmark, Island, Finland, Estland, Ryssland och Tyskland att medverka med artiklar, vilket varit av avgörande vikt med tanke på genrens internationella karaktär. Projektet förbereddes genom ett symposium den 26–28 april 2017 på Språk- och litteraturcentrum, Lunds universitet, benämnt ”Att dikta för livet, döden och evigheten. Nya teorier, metoder och infallsvinklar i forskningen kring tillfällesdiktningen 1500–1800”. Föredragshållarna hade förberetts på att de förväntades omarbeta sina anföranden till vetenskapliga artiklar och att dessa skulle genomgå peer review-process. Det har varit ett övergripande syfte för volymens redaktörer att ordna så att forskningsfältets såväl ämnesmässiga och geografiska bredd som de olika teoretiska och metodiska sätten att närma sig området kommer till sin rätt, och vi har därför kompletterat artiklarna från symposiet med ett antal kortare studier över olika teman.

- Somatic stem cells are ultimately responsible for mediating appropriate organ homeostasis and have therefore been proposed to represent a cellular origin of the ageing process-a state often characterized by inappropriate homeostasis. Specifically, it has been suggested that ageing stem cells might succumb to replicative senescence by a mechanism involving the cyclin-dependent kinase inhibitor p16(INK4A). Here, we tested multiple functional and molecular parameters indicative of p16(INK4A) activity in primary aged murine hematopoietic stem cells (HSCs). We found no evidence that replicative senescence accompanies stem cell ageing in vivo, and in line with p16(INK4A) being a critical determinant of such processes, most aged HSCs (>99%) failed to express p16(INK4A) at the mRNA level. Moreover, whereas loss of epigenetically guided repression of the INK4A/ARF locus accompanied replicative senescent murine embryonic fibroblasts, such repression was maintained in aged stem cells. Taken together, these studies indicate that increased senescence as mediated by the p16(INK4A) tumor suppressor has only a minor function as an intrinsic regulator of steady-state HSC ageing in vivo.

Förhöjd vardaglighet : Unga på landsbygden gör vardag
- 2021
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- I avhandlingen skildras vardagslivet hos en grupp unga som bor på landsbygden. Medan vardagen i regel ses som grå och trist visar avhandlingen hur unga gör den till något särskilt, meningsfullt och roligt, hur de gör förhöjd vardaglighet. Genom att studera ungas vardagsliv med etnografiska metoder och teoretisk nyfikenhet når studien kunskap bortom de problembeskrivningar som vanligtvis skildrar såväl unga som landsbygderna. Avhandlingen visar hur unga gör förhöjd vardaglighet genom utfärder i vardagens vidgade rum, genom att skapa och bemästra osäkra situationer samt genom sällskap och samvaro med människor, djur och prylar. Kunskaper och lärande framträder som en genomgripande dimension av förhöjd vardaglighet, och ofta förbisedda vardagskunskaper uppmärksammas. Avhandlingen lyfter fram värdet av det invanda och alldagliga och visar på behovet av att socialt arbete och liknande praktikområden uppmärksammar vardagslivet och förhöjd vardaglighet.

Social Work in Ghana: Engaging Traditional Actors in Professional Practices
- 2011
-
Ingår i: Journal of Comparative Social Work. - Stavanger : Stavanger University Library. - 0809-9936. ; 6:2, s. 106-124
-
Tidskriftsartikel (refereegranskat)abstract
- In contemporary Ghana, the traditional system and professional social work operate as two parallel systems within the field of social work. The aim of this study was to investigate if and how the teaching of contemporary professional social work in Ghana takes into account traditional actors and practices. The traditional system includes extended family members and traditional authorities such as chiefs or family heads. It formed the social institution that protected and cared for the vulnerable before (Western) social work was introduced as a formal profession in Ghana. A 10-week ethnographic field study was conducted at the Department of Social Work at the University of Ghana. The study employed a qualitative, social constructionist approach, interpreting the results within a theoretical framework of social world theory. The empirical material consisted of interviews with students and teachers, participant observation at lectures, and various documents. The main findings of the study were that professional social workers and traditional actors can be seen as members of two subworlds – the subworld of professional social workers and the subworld of traditional actors. Students and teachers discuss interventions from the perspective of social workers and traditional actors. Their ability to take different perspectives seems to be crucial for localisation – the process by which social work is made relevant to local culture and traditions. The interviewees’ accounts reveal how localisation is not only about culture, but also about social structures and practical considerations. The poor state of the social work profession in Ghana affects interventions in a profound way.

Low-temperature District Heating : Various Aspects of Fourth-generation Systems
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- With decreasing heat demand and less availability of high-temperature heat supply in future energy systems, the current district heating systems may experience increased competition on the heat market. A viable option to mitigate increasing competition is to operate systems with lower temperature levels, and the most conceivable way to achieve lower temperature levels is to decrease return temperatures.In this thesis, aspects of improvements in district heating systems are assessed. Three aspects, in particular, have been analysed. These are integration between energy systems, improvements in heat distribution technology, and economic benefits of low-temperature district heating systems.An increasing interest in integrating different energy systems has been prompted by the rapid introduction of intermittent renewable electricity supply in the energy system. Large-scale conversion of power to heat in electric boilers and heat pumps is a feasible alternative to achieve the balancing capacities required to maintain system functioning. Analysis of the unique Swedish experience using large heat-pump installations connected to district heating systems shows that, since the 1980s, 1527 MW of heat power has been installed, and about 80% of the capacity was still in use in 2013. Thus, a cumulative value of over three decades of operation and maintenance exists within Swedish district heating systems.Increased competition prompted by changes in the operation environment necessitates improved heat distribution. This thesis focuses on three system-embedded temperature errors: first, the temperature error that occurs due to recirculation in distribution networks at low heat demands; second, the temperature error that occurs due to hot-water circulation in multi-family buildings; third, the temperature error that occurs due to lower heat transfer than is possible in heat exchangers (i.e. too-short thermal length). To address these temperature errors, three technology changes have been proposed (i) a three-pipe distribution network to separate the recirculation return flow from the delivery return flow, (ii) apartment substations to eliminate hot-water circulation use, and (iii) improved heat exchangers for lower return temperatures. The analysis of the proposed changes indicates annual average return temperatures between 17°C and 21°C.The final analysed aspect is the economic benefits of low-temperature district heating. It was identified that strong economic motives for lower operating temperatures in future heat supply exist, whereas the economic motives are significantly weaker for the traditional heat supply.The five papers presented in this thesis are related to future district heating systems through the five abilities of fourth-generation district heating (4GDH), which are documented in the definition paper on 4GDH.

Aviculture : A History
- 2018
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- This book discusses the history of aviculture and the cultural extent of keeping and raising birds in captivity for pleasure, companion, ornamental reasons, religious causes or various economic or practical purposes. Since the dawn of mankind, humans have kept birds in captivity. Several species are truly domesticated, while others have simply been bred in captivity for many generations. Today bird-keeping for pleasure appears to be declining in the West, mostly due to bird protection and growing awareness about conservation issues. Although aviculture has had, and still has a deep impact on human beings, it remains a neglected field within humanities and social sciences. Relatively little is published about the cultural and historical aspects of aviculture. This anthology is intended for a general audience of readers and it shows various aspects of keeping birds in captivity for pleasure, ornamental reasons or practical purposes around the world. It also deals with the great variety and complexity of the practice of keeping birds, and the specific cultures which have developed around it. The first chapter gives a brief introduction to the questions we focus on in the book, together with a historic overview from prehistory to early twenty-first century, including pet birds among natives in South America, Southeast Asia and Africa, sailors and their parrots, birds in religious rituals, primitive domesticates in various peasant societies, etc. The other chapters offer descriptive case studies in pre-modern and early modern ways of bird-keeping in various historical contexts. Modern aviculture in zoological gardens is discussed and specific bird categories within twentieth-century aviculture are described in some chapters. We encounter sophisticated bird-keeping in pre-Columbian societies, Norse trade with falcons, the European craze for songbirds, practices with captive birds used in human habitations to keep vermin under control, and how avicultural expertise is used for trying to save vanishing species by breeding them in captivity. Together these topics illustrate the great variety and complexities of bird-keeping practice. The authors are specialists in aviculture and most of them hail from the countries about which they write. This book bridges the disciplines of cultural anthropology, ethnobiology, history, natural history and ornithology and is intended to benchmark the development of the subject for a broader audience, which until now has had few possibilities to become acquainted with it.

Chronic development of collagen-induced arthritis is associated with arthritogenic antibodies against specific epitopes on type II collagen

Tidskriftsartikel (refereegranskat)abstract
- Antibodies against type II collagen (CII) are important in the development of collagen-induced arthritis (CIA) and possibly also in rheumatoid arthritis. We have determined the fine specificity and arthritogenicity of the antibody response to CII in chronic relapsing variants of CIA. Immunization with rat CII in B10.Q or B10.Q(BALB/cxB10.Q)F2 mice induces a chronic relapsing CIA. The antibody response to CII was determined by using triple-helical peptides of the major B cell epitopes. Each individual mouse had a unique epitope-specific response and this epitope predominance shifted distinctly during the course of the disease. In the B10.Q mice the antibodies specific for C1 and U1, and in the B10.Q(BALB/cxB10.Q)F2 mice the antibodies specific for C1, U1 and J1, correlated with the development of chronic arthritis. Injection of monoclonal antibodies against these epitopes induced relapses in chronic arthritic mice. The development of chronic relapsing arthritis, initially induced by CII immunization, is associated with an arthritogenic antibody response to certain CII epitopes.
