  • Pregnancy Rate and Outcome in Swedish Women With Turner Syndrome EDITORIAL COMMENT
  • 2011
  • Ingår i: Obstetrical and Gynecological Survey. - Lippincott Williams & Wilkins. - 1533-9866 .- 0029-7828. ; 66:12, s. 756-757
  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • The rate of spontaneous pregnancies in women with Turner syndrome (TS) is low (2% to 5%). Oocyte donation is an option for these women and enables many to become pregnant. Some investigators question the use of pregnancy induction in TS because of the high risk for aortic dissection or other serious cardiac events. A cardiac evaluation is recommended before pregnancy is planned in TS. Among patients with TS who use their own oocytes to become pregnant, 45% suffered a miscarriage. The aim of this study was to assess pregnancy rate and outcome in a population of Swedish women with spontaneous pregnancies or who were induced using donated oocytes. Cytogenetic karyotype also was examined; mosaicism was defined as the presence of more than 5% 46, XX cells. The study subjects were 482 women with TS who had participated in a voluntary screening program conducted at Swedish Turner Centers. Among the 482 women with TS, 57 (12%) had pregnancies, including spontaneous pregnancies. The live-born rate was 67 of 124 (54%). The patient's own oocytes were used in 27 (47%) of the pregnancies and oocyte donation in 30 (53%) of pregnancies. Spontaneous pregnancies occurred in 23 of 57 women (40%) with TS. Most pregnancies using the patient's own oocytes occurred in those with 45, X/46, XX mosaic karyotype. The miscarriage rate was 26% after oocyte donation and 45% with the use of the patient's own oocytes. Five liveborns (7%) had birth defects or a serious illness; 4 of these were born after spontaneous pregnancies. Only 1 live-born had coarctation of the aorta.

  • Red Meat, Dietary Nitrosamines, and Heme Iron and Risk of Bladder Cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC)
  • 2011
  • Ingår i: Cancer Epidemiology Biomarkers & Prevention. - American Association for Cancer Research. - 1055-9965. ; 20:3, s. 555-559
  • Tidskriftsartikel (övrigt vetenskapligt)abstract
    • Background: Previous epidemiologic studies found inconsistent results for the association between red meat intake, nitrosamines [NDMA: N-nitrosodimethylamine, and ENOC (endogenous nitroso compounds)], and the risk of bladder cancer. We investigated the association between red meat consumption, dietary nitrosamines, and heme iron and the risk of bladder cancer among participants of the European Prospective Investigation into Cancer and Nutrition (EPIC). Methods: Data on food consumption and complete follow-up for cancer occurrence were available for a total of 481,419 participants, recruited in 10 European countries. Estimates of HRs were obtained by proportional hazard models, stratified by age at recruitment, gender, and study center and adjusted for total energy intake, smoking status, lifetime intensity of smoking, duration of smoking, educational level, and BMI. Results: After a mean follow-up of 8.7 years, 1,001 participants were diagnosed with bladder cancer. We found no overall association between intake of red meat (log(2) HR: 1.06; 95% CI: 0.99-1.13), nitrosamines (log(2) HR: 1.09; 95% CI: 0.92-1.30 and HR: 0.98; 95% CI: 0.92-1.05 for ENOC and NDMA, respectively) or heme iron (log(2) HR: 1.05; 95 CI: 0.99-1.12) and bladder cancer risk. The associations did not vary by sex, high-versus low-risk bladder cancers, smoking status, or occupation (high vs. low risk). Conclusions: Our findings do not support an effect of red meat intake, nitrosamines (endogenous or exogenous), or heme iron intake on bladder cancer risk.

  • Hybrid collaborative art practices in contemporary public space
  • 2010
  • Ingår i: Sala d'Art Jove 2009. - Barcelona : Generalitat de Catalunya Departament d’acció Social i Ciutadania. - 978-84-614-2870-0 ; s. 230-237
  • Konstnärligt arbete (övrigt vetenskapligt)abstract
    • Do you see a capacity for transforming the city, its spaces or the use we make of them in artistic practice? Which public spaces do you use most day to day? Is there hope for the Santa Esperança public laundry? Do you think that Somanyprojects’ action has served to reactivate this space and awaken it in the town’s collective imaginary? Do you know of any other public space particular to women? What does the perspective of an artist offer us that an architect’s doesn’t consider when intervening in a space? What does a collaborative art practice consist of? Can an intervention of this type lead to some type of agencement on the part of the community? Would it be viable to consider more alternative uses of water such as public baths? How do you assess artistic practice as a work methodology for participatory urbanism projects? Would you be in favour of other activities being undertaken in public laundries besides washing clothing and the promotion of tourism? Are we very far off on the part of politicians from designing the cities where we want to live based on the needs of the citizens themselves? Do you have any questions for us? Do you have any questions for yourself?

  • Rethinking public space hybrid collaborative art practices and spatial piracy in the urban realm
  • 2011
  • Ingår i: Re-Public. Re-Imagining Democracy. - Greece : http://www.re-public.gr/en. - 1791-857X. ; February 2011
  • Konstnärligt arbete (övrigt vetenskapligt)abstract
    • It seems as if the city, its space, its future, its production, were almost exclusively the result of a series of processes and flows taking place at unreachable distance, in un-known locations, mostly determined by the interests and wills of un-localized powers, actors and flows. As if the city could no longer be produced and shaped after the desires of its inhabitants, articulating one or another form of collective will. As if the city was no longer the soul and reason of urban politics but just the mere object of a kind of witty and hygienic managing that understands built space as a market and a product, placing economy at the very center of society.Urban agendas no longer include distributive and social considerations but focus now on economic growth, competitiveness and entrepreneurship. Creative flexibility, efficiency and strategic partnership exclude dissent, conflict and radical criticism nearly foreclosing the political from the face of the city. Cityspace anesthetized. Public space today is planned, designed, defined, segregated, policed, and set up in order to be easily controlled, ‘secured’, and ‘marketized’, in ways that lead to homogenous, uninteresting, smooth and clean surfaces that differ very much from the inherent characteristics of the very idea of public.

  • Rethinking public space other public spaces: community, hybrid collaborative art practices and urban reactivation
  • 2010
  • Konstnärligt arbete (övrigt vetenskapligt)abstract
    • Rethinking Public Space is a research project by Marta Serra Permanyer and Alberto Altés Arlandis that tries to approach the diverse processes of production and transformation of contemporary public spaces as well the relationships that are often established between art, everyday life and the space of the city. The project, that takes a closer look at a series of interventions in the village of Caldes de Montbui (Barcelona) trying to reflect around the idea of hybrid collaborative art practice, has been possible thanks to a research grant obtained from the Sala’d’Art Jove de la Secretaria de Joventut de la Generalitat de Catalunya.The idea was submitted as a proposal to a call for projects during the year 2008 and was selected in the research category. The project has been carefully and attentively tutored by Montse Romaní, who has been able to provide her experience and help in a very generous way while supervising the project.

  • Implementering av energieffektiviseringsåtgärder i befintlig bebyggelse Report prepared for the Swedish Energy Agency
  • 2010
  • Rapport (övrigt vetenskapligt)abstract
    • There is great potential to improve energy efficiency in existing Swedish residential buildings. However, the successful implementation of efficiency measures depends on economical and technical factors, as well as on the attitudes and perceptions of the relevant actors. A better understanding of their attitudes and perceptions may influence the design of suitable policy measures that increase the adoption of energy efficiency measures. In this context, we conducted mail-in surveys completed by owners of detached houses, chairmen of co-operative housing associations (bostadsrättsförening) and municipality energy advisers in Sweden. We also interviewed window sellers/installers in Jämtland.Results show that it was important for the majority of homeowners to reduce their household energy use, with most undertaking no-cost measures (e.g., switching off lights). However, 70–90% of the responding homeowners had no intention of adopting building envelope measures over the next 10 years. The main reason for non-adoption was that homeowners were satisfied with the physical condition and thermal performance of their existing building envelope components. Homeowners who thought their energy cost was high were more likely to adopt an investment measure compared to those who thought their energy cost was low. Investment costs and annual energy cost savings were the most important factors in adoption of energy efficient building envelope measures. Therefore, economic incentives may induce homeowners to adopt energy efficiency investment measures. However, a large percentage (64%) of homeowners was unaware of the existence of government support for reducing household energy use. Information campaigns announcing the availability of economic incentives and the cost advantages of energy efficiency measures may be helpful in the adoption decision.Homeowners‘ considered interpersonal sources, builders, installers and energy advisers as important sources of information for their adoption of energy efficiency measures. Though a large percentage of respondents considered energy advisers as an important source of information, only 14% of homeowners had contacted an energy adviser in the past. Our findings suggest that the energy advice service is important for homeowners, but more efforts are needed to increase homeowners‘ awareness of and satisfaction with such services. The majority of municipal energy advisers were of the opinion that more training in technical aspects of energy issues and increased financial support could improve their performance.Installers and material suppliers are important actors in homeowners‘ adoption of energy efficiency measures. For example, approximately 53% of responding homeowners to a survey in Jämtland/Västernorrland stated that the window seller/installer from whom they had bought windows had recommended a particular type of window, and 97% had iiinstalled the windows that were recommended. The window sellers/installers in Jämtland prefer a window that is ?reasonably? energy efficient. They believe that windows with a U-value of 1.2 W/m2K are good and there is no reason to further improve the energy efficiency. The majority did not recommend windows with U-value <1.2 W/m2K. They were concerned about the condensation issues and high prices of such windows. This may influence the diffusion of very energy efficient windows in Swedish detached houses.About 80-95% of chairmen in co-operative housing associations who responded to our survey had no intention of adopting building envelope measures over the next 10 years. They were satisfied with the existing building envelope components, which may be one of the reasons for this lack of intention. As in the case of owners of detached houses, economic factors, like annual energy cost savings and investment costs, guide the implementation of energy efficiency investment measures in co-operative housing associations. However, about 66% of the responding chairmen did not consider financial constraint as a barrier to implementing investment intensive energy efficiency measures. For 54% of the respondents limited in-house competency to evaluate the benefits of energy efficiency measures was the main barrier.The majority of owners of detached houses (80%) and chairmen of co-operative housing associations (70%) perceived that economic policy instruments, such as investment subsidies and tax deductions, would encourage them to implement energy efficiency measures. Other policy instruments, especially information instruments, were perceived as less effective. Among various information policies, increasing the frequency of meter reading received the highest approval with 38% of homeowners, whereas approximately 41% of housing association chairmen thought that individual metering of heating and hot water use could be effective. Approximately 30% of homeowners and housing association chairmen thought that energy declaration was effective.
  • History of Participatory Media : Politics and Publics, 1750-2000
  • 2011
  • Samlingsverk (redaktörskap) (övrigt vetenskapligt)abstract
    • This book argues for a historical perspective on issues relating to the notion of participatory media. Working from a broad concept of media – including essays on the 19th century press, early sound media, photography, exhibitions, television and the internet – the book offers a broad empirical approach to different modes of audience participation from the mid 19th century to the present. Using the insights from the historical case studies, the book also explores some of the key concepts in discussions on the politics of participation, arguing for a theoretical perspective sensitive to the asymmetries that characterize the distribution of agency in the relationship between media and users.Scholarly discussions on participatory media now occur in several fields. This book argues that all of these discussions are all too often obscured by a rhetoric of newness, assuming that participatory media is something unique in history, radical and revolutionary. By challenging the historiography implicit in this rhetoric, the book also engages in a discussion of issues of more general relevance to the multidisciplinary field of media history.
