- Comparative analysis of multiple genomes in a phylogenetic framework dramatically improves the precision and sensitivity of evolutionary inference, producing more robust results than single-genome analyses can provide. The genomes of 12 Drosophila species, ten of which are presented here for the first time (sechellia, simulans, yakuba, erecta, ananassae, persimilis, willistoni, mojavensis, virilis and grimshawi), illustrate how rates and patterns of sequence divergence across taxa can illuminate evolutionary processes on a genomic scale. These genome sequences augment the formidable genetic tools that have made Drosophila melanogaster a pre-eminent model for animal genetics, and will further catalyse fundamental research on mechanisms of development, cell biology, genetics, disease, neurobiology, behaviour, physiology and evolution. Despite remarkable similarities among these Drosophila species, we identified many putatively non-neutral changes in protein-coding genes, non-coding RNA genes, and cis-regulatory regions. These may prove to underlie differences in the ecology and behaviour of these diverse species.

- The aim of the paper is to discuss the rising potential of social software to increase the knowledge management capabilities of virtual product development teams. It presents six fundamental transitions, elaborated from the empirical findings, which justify the rise of a more bottom-up, social creation and sharing of engineering knowledge in the virtual organisation. The study suggests that traditional engineering knowledge management approaches alone are not sufficient to support development activities in the virtual organisation, and that such teams display an increasing demand for social, comparatively lightweight and remixable platforms for bottom-up, social creation and sharing of knowledge.

(Re-)Distributional Food Justice : Negotiating conflicting views of fairness within a local grassroots community
- 2023
-
Ingår i: CHI '23: Proceedings of the 2023 CHI Conference on Human Factors in Computing Systems.

Konferensbidrag (refereegranskat)abstract
- Sustainable HCI and Human-Food-Interaction research have developed an interest in preventing food waste through food sharing. Sustainability requires attention to both the opportunities and challenges associated with the building of food-sharing groups engaged in the redistribution of food but also in developing a wider agenda which includes, for instance, the local production of food resources. In this paper, we argue for a better understanding of the different conceptions of ‘fairness’ which inform volunteer and guest practice and in turn mediate community-building efforts. We examine the practices surrounding ‘SharingEvent’ and challenges faced to sustainability by the heterogenous, and sometimes contested, commitments of the people involved. We further consider how ICT provided opportunities for explicit examination of ideological differences concerning what ‘sharing’ might mean. Our findings show that community building is dependent on the negotiation of different values and purposes identified. We derive recommendations for action-oriented researchers ultimately concerned with systemic transformation.

Agile Processes Enhancing User Participation for Small Providers of Off-the-Shelf Software
- 2004
-
Konferensbidrag (refereegranskat)abstract
- To survive in todayrsquos competitive software market, software developers must maintain contact with their customers and users and adopt a flexible organization which allows response to feedback and the changing requirements from the use-context. This also requires a software development that enables change proposals and error reports to be acted upon quickly. The present article uses a case study of a flexible development practice which so far has proved to be sustainable and successful to reconsider user involvement and software development practices of small software providers from an agile perspective. Implementing an agile process may allow for competitive flexibility without necessarily jeopardizing quality.

How to include users in the development of off-the-shelf software : A case for complementing participatory design with agile development
- 2006
-
Konferensbidrag (refereegranskat)abstract
- This paper describes and discusses a non-traditional approach to participatory design, one which is combined with an agile-like software development process. In this case, the size of the company combined with a distributed population of users has a serious impact on the software development process. The small software company in our study resolves this problem with an unconventional amalgam of participatory design and agile processes which seems to suit their situation. By using different kinds of user participation the small software provider is able to keep in contact with users on a daily basis. Users convey requirements for new functionalities, give feedback and report errors. Users' feedback and proposals form the basis for further development. The paper relates our observations to other research on participatory design in unconventional settings and discusses the conditions under which agile software development can complement participatory design.

The development is driven by our users not by ourselves-including users in the development of off-the-shelf software
- 2003
-
Konferensbidrag (refereegranskat)abstract
- This article describes a non-traditional approach to Participatory Design where distributed users have a serious impact on a software development process. The small software provider makes use of a non-traditional way of Participatory Design combined with an agile development approach. By using for among other things support service, user meetings, courses and news letter they are able to on a daily bases keep in contact with users. Users convey requirements for new functionalities, give feedback and report errors. Users’ feedback and proposals form the base for further development. Frequent re-leases allow the company to quickly implement improvements and bug-fixes. The article relates the observed practices to other research on Participatory Design in unconventional settings and discusses how to expand the Participatory Design toolbox.

Sequence and comparative analysis of the chicken genome provide unique perspectives on vertebrate evolution
- 2004

Ingår i: Nature. - 0028-0836 .- 1476-4687. ; 432:7018, s. 695-716

Tidskriftsartikel (refereegranskat)abstract
- We present here a draft genome sequence of the red jungle fowl, Gallus gallus. Because the chicken is a modern descendant of the dinosaurs and the first non-mammalian amniote to have its genome sequenced, the draft sequence of its genome--composed of approximately one billion base pairs of sequence and an estimated 20,000-23,000 genes--provides a new perspective on vertebrate genome evolution, while also improving the annotation of mammalian genomes. For example, the evolutionary distance between chicken and human provides high specificity in detecting functional elements, both non-coding and coding. Notably, many conserved non-coding sequences are far from genes and cannot be assigned to defined functional classes. In coding regions the evolutionary dynamics of protein domains and orthologous groups illustrate processes that distinguish the lineages leading to birds and mammals. The distinctive properties of avian microchromosomes, together with the inferred patterns of conserved synteny, provide additional insights into vertebrate chromosome architecture.

Knowledge maturity as decision support in stage-gate product development : a case from the aerospace industry
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In today’s fast-paced industry where fight for market share is fierce and reaching the market ahead of competition imperative, product development is a target for lead-time reductions. In this context, in product development in stage-gate processes, decisions need to be made even though knowledge and information are scarce and flawed. The challenge is how to support the decisions that are made in light of uncertainty and ambiguity. The thesis moves from analysing the role of the stage-gate process within the aerospace industry. The stage-gate process was more than a decision making mechanism, and instead a mechanism that facilitated communication, discussion and knowledge sharing between team members, as well as supported knowledge creation and shaping of the boundaries between people’s different perceptions of the knowledge base. However, the communicative and negotiative function of the stage-gate was highly dependent on the ability of the participating individuals to reflect on the status and quality of the available knowledge assets used throughout the process. To make this reflective activity an explicit part of the stage-gate practice, this thesis proposes the application of a knowledge maturity concept at the gates to raise the decision makers’ awareness of the status of the knowledge assets handled at the decision point. The knowledge maturity concept considers three basic dimensions: input, method/tool and experience/expertise in assessing the knowledge base maturity. The scale is intended to act as a boundary object, facilitating the knowledge creation process by highlighting the current status of the knowledge base and making stakeholders aware of the nature of the project’s uncertainties and ambiguities. In the knowledge maturity concept, its purpose is to support design teams at the gates in taking appropriate action, mitigating risk and focusing their efforts on improving the knowledge assets where it is needed most, regarding the situation at hand and, finally, to make more confident decisions.The thesis was developed within the EU FP6 VIVACE (Value Improvement through a Virtual Aeronautical Collaborative Enterprise) and EU FP7 CRESCENDO (Collaborative and Robust Engineering using Simulation Capability Enabling Next Design Optimisation) projects, and within the Faste Laboratory, a VINNOVA Excellence Centre involving partners from the Swedish manufacturing industry.
