    Applying Design Thinking Elsewhere: Organizational context matters

    Full text link
    In this contribution design thinking is taken as a transfer of design methods from product development to other domains. It is argued that the success of this transfer depends on the organisational context offered to design thinking in these other domains. We describe the application of design methods in product development and in two new domains by what we have called the IDER model, where D refers to design and I, E and R to the organisational context. Then we show that characteristics of the contexts in the new domains may determine the success of applying design thinking in these domains. Finally we focus on the transitions among design and the other contextual elements as another source that can ‘make or break’ the success of applying design thinking. We support our arguments with two cases of design thinking: social design and business-innovation design

    OBJECTIVE: To investigate the biomedical scientist's perception of the prevailing publication culture. DESIGN: Qualitative focus group interview study. SETTING: Four university medical centres in the Netherlands. PARTICIPANTS: Three randomly selected groups of biomedical scientists (PhD, postdoctoral staff members and full professors). MAIN OUTCOME MEASURES: Main themes for discussion were selected by participants. RESULTS: Frequently perceived detrimental effects of contemporary publication culture were the strong focus on citation measures (like the Journal Impact Factor and the H-index), gift and ghost authorships and the order of authors, the peer review process, competition, the funding system and publication bias. These themes were generally associated with detrimental and undesirable effects on publication practices and on the validity of reported results. Furthermore, senior scientists tended to display a more cynical perception of the publication culture than their junior colleagues. However, even among the PhD students and the postdoctoral fellows, the sentiment was quite negative. Positive perceptions of specific features of contemporary scientific and publication culture were rare. CONCLUSIONS: Our findings suggest that the current publication culture leads to negative sentiments, counterproductive stress levels and, most importantly, to questionable research practices among junior and senior biomedical scientists

    Published in: Appl. Phys. Lett. 66 (1995) 2733-2735 citations recorded in [Science Citation Index] Abstract: Radioactive Li ions were implanted into natural IIa diamonds at temperatures between 100 K and 900 K. Emission channelling patterns of a-particles emitted in the nuclear decay of 8Li (t1/2 = 838 ms) were measured and, from a comparison with calculated emission channelling and blocking effects from Monte Carlo simulations, the lattice sites taken up by the Li ions were quantitatively determined. A fraction of 40(5)% of the implanted Li ions were found to be located on tetrahedral interstitial lattice sites, and 17(5)% on substitutional sites. The fractions of implanted Li on the two lattice sites showed no change with temperature, indicating that Li diffusion does not take place within the time window of our measurements.

    Breakdown of anomalous channeling with ion energy for accurate strain determination in gan-based heterostructures

    The influence of the beam energy on the determination of strain state with ion channeling in GaN-based heterostructures (HSs) is addressed. Experimental results show that anomalous channeling may hinder an accurate analysis due to the steering effects at the HS interface, which are more intense at lower ion energies. The experimental angular scans have been well reproduced by Monte Carlo simulations, correlating the steering effects with the close encounter probability at the interface. Consequently, limitations in the determination of the strain state by ion channeling can be overcome by selecting the adequate beam energy

    Modelling Co-Evolution in Design Practice

    Full text link
    Co-evolution is considered as a key characteristic of designing. Several authors have described design thinking processes as the co-evolution of design problem and design solution. 1Is theoretical grounding is, however, still in an early stage. In this paper, we aim to bring the concept further by studying a real life design meeting of an architect and a client. We developed a model of how eo-evolution in a multiparty setting might work, consisting of the problems as perceived by the architect and client, the solutions as perceived by the architect and client, and relations between those. A co-evolution episode starts with introducing an underdeveloped design-solution pairing from the perspective of the initiating actor and ends with summing up the discussion and/or agreeing on the decisions taken. The developed model was used to look in detail at the utterances in three co-evolution episodes and then refined by adding a intermediate space concerning the 'use' of the building that mediates between problem and solution spaces in interactions between designer and client

    Risk Assessment for Huntington's Disease for (Future) Offspring Requires Offering Preconceptional CAG Analysis to Both Partners

    Amongst the main reasons people at risk for Huntington's disease (HD) have for undergoing predictive genetic testing are planning a family and prevention of passing on an expanded CAG-repeat to future offspring. After having received an unfavourable test result, a couple may consider prenatal testing in the foetus or preimplantation genetic diagnostic testing (PGD) in embryos. Testing of the foetus or embryos is possible by means of direct testing of the expanded repeat. Optimal reliability in testing the foetus or embryos requires the establishment of the origin of the repeats of both parents in the foetus. For PGD the analysis is combined with or sometimes solely based on identification of the at-risk haplotype in the embryo. This policy implies that in the context of direct testing, the healthy partner's CAG repeat lengths in the HD gene are also tested, but with the expectation that the repeat lengths of the partner are within the normal range, with the proviso that the partner's pedigree is free of clinically confirmed HD. However, recent studies have shown that the expanded repeat has been observed more often in the general population than previously estimated. Moreover, we have unexpectedly observed an expanded repeat in the non-HD partner in four cases which had far-reaching consequences. Hence, we propose that in the context of reproductive genetic counselling, prior to a planned pregnancy, and irrespective of the outcome of the predictive test in the HD-partner, the non-HD partner should also be given the option of being tested on the expanded allele. International recommendations for predictive testing for HD should be adjusted.Genetics of disease, diagnosis and treatmen
