- Arrangements for collaboration in knowledge production across academia, government, non-governmental organisations, and corporations have several names, such as citizen-science, community-based participatory research, engaged research and hybrid forums. The multiplicity of schemes does not lie only in the high number of names for various versions of collaborative knowledge production. Different scholars also use concepts in multiple ways, depending on their individual choices, mother disciplines, and the problem area in which collaboration occurs. At the same time, there is a lack of analytical tools that address the full range of collaborative research schemes and provide a systematic set of questions to learn about the schemes, challenges, and opportunities. Based on our review of academic journal articles highlighting collaborative research schemes, this paper aims to analyse three parameters which it is fair to say that virtually all arrangements of collaborative knowledge production ought to consider when making decisions, parameters that are often partially missed or misunderstood: (A) epistemic-procedural, (B) exclusive-inclusive and (C) aggregative-integrative. By examining the three parameters, their political theory origins, and how they connect to and challenge existing schemes of knowledge collaboration, we provide analytical tools that could facilitate processes of developing and scrutinising arrangements of collaborative research.

Conference paper (peer-reviewed)abstract
- The European Spallation Source is being constructed in Lund, Sweden and is planned to be the world's brightest pulsed spallation neutron source for cold and thermal neutron beams (≤ 1 eV). The facility uses a 2 GeV proton beam to produce neutrons from a tungsten target. The neutrons are then moderated in a moderator assembly consisting of both liquid hydrogen and water compartments. Surrounding the moderator are 22 beamports, which view the moderator's outside surfaces. The beamports are connected to long neutron guides that transport the moderated neutrons to the sample position via reflections. As well as the desired moderated neutrons, fast neutrons coming directly from the target can find their way down the beamlines. These can create unwanted sources of background for the instruments. To mitigate such a kind of background, several instruments will use curved guides to lose direct line-of-sight (LoS) to the moderator and the target. In addition instruments can also use shielding collimators to reduce the amount of fast neutrons further traveling down the guide due to albedo reflections or streaming. Several different materials have been proposed for this purpose. We present the results of a study of different options for collimators and identify the optimal choices that balance cost, background and activation levels.

A family of experiments on test-driven development

Journal article (peer-reviewed)abstract
- Context:: Test-driven development (TDD) is an agile software development approach that has been widely claimed to improve software quality. However, the extent to which TDD improves quality appears to be largely dependent upon the characteristics of the study in which it is evaluated (e.g., the research method, participant type, programming environment, etc.). The particularities of each study make the aggregation of results untenable. Objectives:: The goal of this paper is to: increase the accuracy and generalizability of the results achieved in isolated experiments on TDD, provide joint conclusions on the performance of TDD across different industrial and academic settings, and assess the extent to which the characteristics of the experiments affect the quality-related performance of TDD. Method:: We conduct a family of 12 experiments on TDD in academia and industry. We aggregate their results by means of meta-analysis. We perform exploratory analyses to identify variables impacting the quality-related performance of TDD. Results:: TDD novices achieve a slightly higher code quality with iterative test-last development (i.e., ITL, the reverse approach of TDD) than with TDD. The task being developed largely determines quality. The programming environment, the order in which TDD and ITL are applied, or the learning effects from one development approach to another do not appear to affect quality. The quality-related performance of professionals using TDD drops more than for students. We hypothesize that this may be due to their being more resistant to change and potentially less motivated than students. Conclusion:: Previous studies seem to provide conflicting results on TDD performance (i.e., positive vs. negative, respectively). We hypothesize that these conflicting results may be due to different study durations, experiment participants being unfamiliar with the TDD process, or case studies comparing the performance achieved by TDD vs. the control approach (e.g., the waterfall model), each applied to develop a different system. Further experiments with TDD experts are needed to validate these hypotheses. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC part of Springer Nature.

Acute Respiratory Distress Syndrome deteriorates pulmonary vascular efficiency and increases cardiac energy wasting in a porcine model.
-
Other publication (other academic/artistic)abstract
- Background: Right ventricle failure worsen outcomes in acute respiratory distress syndrome (ARDS). However, the pathophysiology of right ventricle failure and vascular dysfunction in ARDS is not completely understood. In this study we aim to evaluate the effects of early ARDS on pulmonary vascular efficiency for transmission of flow and pressure in an experimental animal model. Methods: ARDS was induced in 10 pigs (32.5±4.3 kg) combining saline lung-lavages with injurious mechanical ventilation. Pressure and flow sensors were placed at the main pulmonary artery for pulmonary vascular function evaluation, including arterial load parameters, cardiac power and energy transmission ratio.Results: Compared to baseline healthy conditions, ARDS increased pulmonary vascular resistance (199±62 versus 524±154 dyn.s.cm-5, p <0.001), effective arterial elastance (0.65±0.26 versus 1.13±0.36 mmHg/ml, p <0.001) and total hydraulic power (195±60 to 266±87 mW, p =0.015), decreased pulmonary arterial compliance (from 2.34±0.86 to 1.00±0.25 ml/mmHg, p <0.001) and energy transmission ratio (68±15 versus 55±14%, p = 0.014), whereas oscillatory power did not change (17±6 versus 16±6%, p = 0.359).Conclusions: In this experimental ARDS model, an increase in pulmonary arterial load was associated with a higher cardiac power and a decrease in the energy transmission ratio. These results suggest that right ventricle energy consumption is increased and part of this energy is wasted in pulmonary circulation worsening pulmonary vascular efficiency in the early course of ARDS. These findings may help to explain primary mechanisms leading to right ventricle dysfunction in ARDS.
