- 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.

- The origin and evolution of the domestic dog remains a controversial question for the scientific community, with basic aspects such as the place and date of origin, and the number of times dogs were domesticated, open to dispute. Using whole genome sequences from a total of 58 canids (12 gray wolves, 27 primitive dogs from Asia and Africa, and a collection of 19 diverse breeds from across the world), we find that dogs from southern East Asia have significantly higher genetic diversity compared to other populations, and are the most basal group relating to gray wolves, indicating an ancient origin of domestic dogs in southern East Asia 33 000 years ago. Around 15 000 years ago, a subset of ancestral dogs started migrating to the Middle East, Africa and Europe, arriving in Europe at about 10 000 years ago. One of the out of Asia lineages also migrated back to the east, creating a series of admixed populations with the endemic Asian lineages in northern China before migrating to the New World. For the first time, our study unravels an extraordinary journey that the domestic dog has traveled on earth.

- Hintergrund und Fragestellung: Spielersperren stellen eine effektive Maßnahme des Spielerschutzes dar. Sie bedürfen jedoch einer Anpassung an die Bedürfnisse von Personen mit Glücksspielproblemen. Studien weisen auf Defizite hinsichtlich Sperrvorgang und -dauer sowie Zugangskontrollen hin. Ziel der qualitativen Untersuchung war es, Empfehlungen für die Optimierung von Spielersperren abzuleiten. Methodik: Mit semi-strukturierten Leitfäden wurden die am Prozess einer Spielesperre beteiligten Akteure zu Regelungen der Spielersperre, persönlichen Erfahrungen und Barrieren befragt. Einbezogen wurden Glücksspielende mit und ohne Sperre sowie Angehörige, Fachkräfte, Mitarbeitende von Spielbanken, Spielhallen und der Gesellschaft für Spielerschutz und Prävention (GSP). Insgesamt wurden 20 Einzel- und sechs Gruppeninterviews geführt. Ergebnisse: Als zentrale Ansatzunkte der Optimierung wurden Sperrdauer und -umfang (übergreifendes Sperrsystem) sowie Zugangskontrollen genannt. Empfohlen wurden eine Antragstellung über Post oder Internet zur Senkung der Hemmschwelle und ein rascheres Inkrafttreten der Spielersperre. Kontrovers diskutiert wurden Sperrdauer und Optionen einer Entsperrung. Durch den Einsatz einer Spielerkarte versprachen sich die Befragten eine Verbesserung des Spielerschutzes durch Feststellung einer laufenden Spielersperre und Begrenzung von Spielzeit oder Geldeinsätzen. Diskussion: Spielersperren wurden von allen Befragten grundsätzlich positiv bewertet. Optimierungsbedarf wurde in den gesetzlichen Regelungen und Sperrkonditionen gesehen. Von einer Schließung von Gesetzeslücken sowie einer intensiven Aufklärung und Motivation von Glücksspielenden, Angehörigen und Glücksspielanbietern werden positive Effekte auf die Inanspruchnahme von Spielersperren erwartet.

Konferensbidrag (refereegranskat)abstract
- While the real-time systems community has developed very valuable approaches to timing and scheduling analysis for processors and buses over the last four decades, another very relevant issue has received only limited attention: end-to-end timing. Most of the known work poses restrictions on specific task activation and communication mechanisms, e.g. unbounded FIFO queues along event-triggered paths. In automotive systems, however, register buffers and periodic sampling are far more common. In this paper, we present a formal framework for the calculation of end-to-end latencies in multi-rate, register-based systems. We show that in systems with sampling, analysis must distinguish between different "meanings" of end-to-end timing. For instance, control engineers are mostly concerned with the "maximum age of data", i.e. the worst-case timing of the latest possible signal. In body electronics, the "first reaction" is key, i.e. worst-case timing of the earliest possible signal. Because the analysis of either case can be different, a clear distinction is mandatory. This paper gives examples and introduces the notion of such end-to-end timing semantics, thereby considering the specific mechanisms and effects typically found in automotive execution platforms such as over- and under-sampling and jitter.

- Despite suicide ideation being one of the most frequently reported health issues impacting tertiary students, there is a paucity of research evaluating the efficacy of preventive interventions aimed at improving mental health outcomes for students studying at two tertiary institutes. The current study evaluated the efficacy of the “Talk-to-Me” Mass Open Online Course (MOOC) in improving tertiary students’ abilities to support the mental health of themselves and their peers via a randomised controlled trial design, comparing them to a waitlist control group. Overall, 129 tertiary students (M = 25.22 years, SD = 7.43; 80% female) undertaking a health science or education course at two Western Australian universities were randomly allocated to either “Talk-to-Me” (n = 66) or waitlist control (n = 63) groups. The participants’ responses to suicidal statements (primary outcome), knowledge of mental health, generalised self-efficacy, coping skills, and overall utility of the program (secondary outcomes) were collected at three timepoints (baseline 10-weeks and 24-weeks from baseline). Assessment time and group interaction were explored using a random-effects regression model, examining changes in the primary and secondary outcomes. Intention-to-treat analysis (N = 129) at 10-weeks demonstrated a significant improvement in generalised self-efficacy for “Talk-to-Me” compared to the control group (ES = 0.36, p = .04), with only the “Talk-to-Me” participants reporting increased knowledge in responding to suicidal ideation (primary outcome). This change was sustained for 24 weeks. Findings provide preliminary evidence suggesting that the “Talk-to-Me” MOOC can effectively improve tertiary students’ mental health and knowledge of how to support themselves and others in distress.

Development of New Chiral Bicyclic Ligands : Applications in Catalytic Asymmetric Transfer Hydrogenation, Epoxidations, and Epoxide Rearrangements
- 2005
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis describes the synthesis and application of new chiral bicyclic ligands and their application in asymmetric catalysis. The studies involved: [i] The development of novel chiral bicyclic amino sulfur ligands and their use in transfer hydrogenation. [ii] The development of the kinetic resolution of racemic epoxide through the use of chiral lithium amides. [iii] The synthesis and application of chiral bicyclic amine in the organocatalysed epoxidation of alkenes. [iv] Development and application of new chiral diamine ligands in the rearrangement of epoxides into allylic alcohols.[i] The preparation of two-series of amino thiol ligands based on the structure of camphor is described, together with their application in the iridium-catalysed asymmetric transfer hydrogenation of acetophenone using isopropanol as the hydrogen source. Excellent activity and good enantioselectivity have been achieved using 2 mol% of chiral ligand in combination with [IrCl(COD)]2.[ii] The chiral diamines (1S,3R,4R)-3-(pyrrolidine-1-ylmethyl)-2-aza-bicyclo[2.2.1]heptane and its (2R,5R)-dimethylpyrrolidine derivative were applied to the kinetic resolution of a variety of racemic 5-7 membered cycloalkene oxides with lithium diisopropylamide (LDA) as the bulk base. Using 5 mol% of the chiral diamines, both unreacted epoxides and allylic alcohols could be produced in enantiomeric excess up to 99%.[iii] The synthesis of chiral bicyclic amines and their use in the organocatalysed epoxidation of alkene has been described. Using a substoichiometric amount of the chiral amines and aldehydes as ligands precursors, with Oxone® as oxidant, a good activity but moderate enantioselectivity was observed for the epoxidation of trans-stilbene. [iv] The preparation of 6-substituted-7-bromo-aza-bicyclo[2.2.1]heptanes via nucleophilic addition of organocopper reagents to 3-bromo-1-azoniatricyclo[2.2.1.0]heptyle bromide has been described. These compounds have been utilised as chiral building blocks in the preparation of novel chiral diamine ligands, which have been successfully applied to the catalysed asymmetric rearrangement of epoxide into the corresponding allylic alcohol.
