Narcolepsy risk loci outline role of T cell autoimmunity and infectious triggers in narcolepsy
- 2023
-
Ingår i: Nature Communications. - : Springer Nature. - 2041-1723. ; 14
-
Tidskriftsartikel (refereegranskat)abstract
- Narcolepsy type 1 (NT1) is caused by a loss of hypocretin/orexin transmission. Risk factors include pandemic 2009 H1N1 influenza A infection and immunization with Pandemrix (R). Here, we dissect disease mechanisms and interactions with environmental triggers in a multi-ethnic sample of 6,073 cases and 84,856 controls. We fine-mapped GWAS signals within HLA (DQ0602, DQB1*03:01 and DPB1*04:02) and discovered seven novel associations (CD207, NAB1, IKZF4-ERBB3, CTSC, DENND1B, SIRPG, PRF1). Significant signals at TRA and DQB1*06:02 loci were found in 245 vaccination-related cases, who also shared polygenic risk. T cell receptor associations in NT1 modulated TRAJ*24, TRAJ*28 and TRBV*4-2 chain-usage. Partitioned heritability and immune cell enrichment analyses found genetic signals to be driven by dendritic and helper T cells. Lastly comorbidity analysis using data from FinnGen, suggests shared effects between NT1 and other autoimmune diseases. NT1 genetic variants shape autoimmunity and response to environmental triggers, including influenza A infection and immunization with Pandemrix (R).

Design of linear and efficient power amplifiers by generalization of the Doherty theory
- 2017
-
Ingår i: Proceedings of the 2017 IEEE Topical Conference on Power Amplifiers for Wireless and Radio Applications. - 9781509034574 ; , s. 29-32

Konferensbidrag (refereegranskat)abstract
- The Doherty power amplifier (PA) is now established as one the most widely adopted architectures for enhancement of energy efficiency in wireless communication transmitters. More than 80 years after its invention, most of today's implementations still rely on the original circuit topology. This paper describes a new Doherty solution continuum that is revealed when the original λ/4 combiner is replaced by a generic, analytically derived, lossless combiner network. As a result, novel Doherty PA solutions that in practice are both more efficient and more linear are enabled. A variety of practical design examples are included to illustrate how the presented techniques can enable enhanced performance in both traditional and emerging mm-wave 5G wireless communication transmitter applications.

Case studies of Kenyan digital villages with a focus on women and girls
- 2011
-
Ingår i: Journal of Language, Technology & Entrepreneurship in Africa. - : African Journals Online (AJOL). - 1998-1279 .- 2309-5814. ; 3:1, s. 255-273
-
Tidskriftsartikel (refereegranskat)abstract
- The present article refers to a case study on the Kenyan Government’s Digital Villages Project (DVP). The Kenyan Government, together with external stakeholders and private contractors, is increasing their ICT investments to provide the entire population with information and communication regardless of demographic factors. In the Kenyan context, digital villages are what normally other countries refer to as telecentres, i.e. a centre that provides services with regard to Internet and telecommunication. In this case, the digital villages also offer education, learning, and e-Government. The present study wants to learn whether DVP is accessible, and appropriate to women and girls in resource-poor environments and, thus, successful. The following questions guided the study: 1. Who are the users of Pasha Centres? 2. How and for what purposes are Pasha Centres used? 3. In what way do Pasha Centres consider local needs (e.g. education, literacy, job, and diversity)? 4. What do users and managers do to encourage female users? The study is built upon observations and interviews. The results show that male users generally believe that women have a lack of knowledge and understanding of ICT. The results also show that what is said by the government is not fully implemented at the local levels. The authors believe, despite this, that DVP has the potential to serve the population in vulnerable areas and that the government should continue focusing on similar projects.

Constraints of ICT in lifelong learning on disadvantaged women
- 2014
-
Ingår i: The Electronic Journal of Information Systems in Developing Countries. - Hongkong : Wiley. - 1681-4835. ; 61:8, s. 1-14
-
Tidskriftsartikel (refereegranskat)abstract
- This paper draws attention to the urgency of taking into consideration women’s genderspecific needs and interests in the implementation of community-based ICT projects in lifelong learning. We set out this research to understand the constraints of information and communications technology (ICT) in lifelong learning on disadvantaged women. National statistics and data from field studies were used. The constraints and their consequences at national level are often a result of national policies and regulations – or lack thereof – while the constraints and their consequences at local/regional level involve everyday-life occurrences that are present in women's immediate surroundings. Hence, an understanding of both levels is critical. This research is valuable for stakeholders delving into issues of development intervention using ICTs, not only in Kenya but in a broader, global perspective.

Empowering rural women in Kenya with literacy skills using web 2.0 : experiences of language & communication barriers in learning
- 2010
-
Ingår i: ICIA 2010 Proceedings. ; , s. 100-110
-
Konferensbidrag (refereegranskat)abstract
- Abstract. The purpose of this paper is to illuminate ways in which language and communication relatedbarriers may be experienced in learning. Because of increased ICT usage, Project Africa’s Women’sAcademy, that is in focus of the research, felt that some issues regarding language and communicationappeared in another way than before without using ICT. The research was conducted in Lunga-Lunga,Kenya, November 2009 and through Internet communication (e.g. logs, letters stored in a socialnetworking site). The paper mainly draws on literature on ICT and Joseph Kaipayil’s ontology to collectindividual ‘experiences’. The results show that many barriers arise because of cultural diversities amongthe learners; e.g. difference ways of employing concepts and regard the objects in the world. In makingpolicies, therefore, account must be taken on a local and individual level as well as on a transnationaland collective level.

Lifelong learning : The social impact of digital villages as community resource centres on disadvantaged women
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this research was to enhance the understanding of what affects the social impact of ICT in lifelong learning on disadvantaged women.In contributing to the field of social informatics, this research employs behavioural theories as strategy and analytic possibilities. This research mainly used the Kenyan digital villages as CRCs as settings but did also look beyond such establishments to provide a more solid picture. The studies were located in Kenya with complementary studies in Bolivia, Cameroon, Sri Lanka, and Sweden. The main strategies and methods used were case study, comparative education approaches, and observations and interviewing techniques.The findings suggest that ICT and CRCs have the potential to support disadvantaged women and their lifelong learning. However, the positive social impacts are limited because the arrangement of them generally does not favour vernacular languages, illiterate users, female owners and users, or non-students. In general, the use of ICT was sometimes perceived as forced, which is both a barrier and a stressor in the use of ICT in lifelong learning. It also emerged from the comparative studies that discussions among the participants in the CRCs largely covered issues in respect to 1) family and reproduction and 2) self-esteem, i.e. what settles the matter of the social impact of ICT in lifelong learning depends on change attitude among men and women. With minimal if not zero self-esteem a change that would make the difference or break a woman’s “legendary status quo” in order for a woman to feel that she can reach her goal or ambitions in lifelong learning would be difficult. Hence the lack of self-esteem is a stressor in itself.This research is valuable for stakeholders delving into issues of development and learning using ICTs, not only in Kenya but in a broader, global perspective.
