description: We present a uniform asymptotic expansion of the wobbling kink to any order in the amplitude of the wobbling mode. The long-range behaviour of the radiation is described by matching the asymptotic expansions in the far field and near the core of the kink. The complex amplitude of the wobbling mode is shown to obey a simple ordinary differential equation with nonlinear damping. We confirm the $t^{-1/2}$-decay law for the amplitude which was previously obtained on the basis of energy considerations.

description: The paper explores the ecological effects of a policy change from coupled direct payments to decoupled single farm payments in a case study region in Germany. Since decoupling is expected to affect agricultural production and trade, both statically with respect to the incentive prices of agricultural inputs or outputs, and dynamically with respect to their investment decisions, we have developed a modelling approach that is built on two micro-economic models â€“ AgriPoliS (agent-based) and MODAM (linear programming + fuzzy-logic-based environmental impact assessment). The model linking makes it possible to analyse dynamically both structural change of the farming sector and agricultural-management-related environmental impacts. Our analysis comes to ambiguous results. In comparison to Agenda 2000, payment decoupling leads to greater land abandonment and reduced stocking numbers, especially in the beef sector. On arable land, the trend goes towards intensification, while on grassland cross-compliance leads to a more extensive agricultural management.

description: Two-step crystallization via a metastable intermediate phase is often regarded as a non-classical process that lies beyond the framework of classical nucleation theory (CNT). In this work, we investigate two-step crystallization in colloid-polymer mixtures via an intermediate liquid phase. Using CNT-based seeding simulations, we construct a kinetic phase diagram that identifies regions of phase space where the critical nucleus is either liquid or crystalline. These predictions are validated using transition path sampling simulations at nine different relevant state points. When the critical nucleus is liquid, crystallization occurs stochastically during the growth phase, whereas for a crystalline critical nucleus, the crystallization process happens pre-critically at a fixed nucleus size. We conclude that CNT-based kinetic phase diagrams are a powerful tool for understanding and predicting `non-classical' crystal nucleation mechanisms.

Influence of simple quantum corrections on the thermophysical properties of water
Creators: name: Savoia, Edoardo
Publisher: name: Swinburne
Year: 2025

description: This research explores how quantum corrections can improve the accuracy of simulations used to study the physical properties of liquid water. By comparing two widely used water models, the study identifies key limitations in classical simulations and evaluates correction methods to improve agreement with experimental data. The findings help refine computational models, leading to better predictions of water’s behaviour under different conditions. This research benefits fields such as material science and climate modelling, where understanding water’s properties is essential for accurate simulations of natural and industrial processes.

description: We propose a network characterization of combinatorial fitness landscapes by adapting the notion of inherent networks proposed for energy surfaces (Doye, 2002). We use the well-known family of $NK$ landscapes as an example. In our case the inherent network is the graph where the vertices are all the local maxima and edges mean basin adjacency between two maxima. We exhaustively extract such networks on representative small NK landscape instances, and show that they are 'small-worlds'. However, the maxima graphs are not random, since their clustering coefficients are much larger than those of corresponding random graphs. Furthermore, the degree distributions are close to exponential instead of Poissonian. We also describe the nature of the basins of attraction and their relationship with the local maxima network.

description: Tropical forests modify the conditions they depend on through feedbacks at different spatial scales. These feedbacks shape the hysteresis (history-dependence) of tropical forests, thus controlling their resilience to deforestation and response to climate change. Here, we determine the emergent hysteresis from local-scale tipping points and regional-scale forest-rainfall feedbacks across the tropics under the recent climate and a severe climate-change scenario. By integrating remote sensing, a global hydrological model, and detailed atmospheric moisture tracking simulations, we find that forest-rainfall feedback expands the geographic range of possible forest distributions, especially in the Amazon. The Amazon forest could partially recover from complete deforestation, but may lose that resilience later this century. The Congo forest currently lacks resilience, but is predicted to gain it under climate change, whereas forests in Australasia are resilient under both current and future climates. Our results show how tropical forests shape their own distributions and create the climatic conditions that enable them.

description: By means of a survey among arable farmers the interest for multi-peril crop insurance was studied and the role public policy should play according to farmers was elicited. While the majority of the respondents were in favour of a public-private insurance scheme, a substantial part of the respondents regarded these types of risks as a business risk which should be borne by the farmers themselves or considered the risks as not threatening for the continuity of their farm. Government participation was found to be desirable, particularly in the form of enabling re-insurance. Farmers also feel that there should be more harmonisation between the various schemes in Europe and the extent of government support.

description: Weak gravitational lensing provides a unique method to map directly the dark matter in the Universe. The majority of lensing analyses uses the two-point statistics of the cosmic shear field to constrain the cosmological model yielding degeneracies, such as that between sigma_8 and Omega_M respectively the r.m.s. of the mass fluctuations at a scale of 8 Mpc/h and the matter density parameter both at z = 0. However, the two-point statistics only measure the Gaussian properties of the field and the weak lensing field is non-Gaussian. It has been shown that the estimation of non-Gaussian statistics on weak lensing data can improve the constraints on cosmological parameters. In this paper, we systematically compare a wide range of non-Gaussian estimators in order to determine which one provides tighter constraints on the cosmological parameters. These statistical methods include skewness, kurtosis and the Higher Criticism test in several sparse representations such as wavelet and curvelet; as well as the bispectrum, peak counting and a new introduced statistic called Wavelet Peak Counting (WPC). Comparisons based on sparse representations show that the wavelet transform is the most sensitive to non-Gaussian cosmological structures. It appears also that the best statistic for non-Gaussian characterization in weak lensing mass maps is the WPC. Finally, we show that the sigma_8 -Omega_m degeneracy could be even better broken if the WPC estimation is performed on weak lensing mass maps filtered by the wavelet method, MRLens.

description: Joking draws on complex cognitive abilities: understanding social norms, theory of mind, anticipating others' responses, and appreciating the violation of others’ expectations. Playful teasing, which is present in preverbal infants, shares many of these cognitive features. There is some evidence that great apes can tease in structurally similar ways, but no systematic study exists. We developed a coding system to identify playful teasing and applied it to video of zoo-housed great apes. All four species engaged in intentionally provocative behaviour, frequently accompanied by characteristics of play. We found playful teasing to be characterized by attention-getting, one-sidedness, response looking, repetition and elaboration/escalation. It takes place mainly in relaxed contexts, has a wide variety of forms, and differs from play in several ways (e.g. asymmetry, low rates of play signals like the playface and absence of movement-final ‘holds’ characteristic of intentional gestures). As playful teasing is present in all extant great ape genera, it is likely that the cognitive prerequisites for joking evolved in the hominoid lineage at least 13 million years ago.

Photoexcited dipolar excitons were collected in a lateral trap in GaAs/AlGaAs Schottky-diode heterostructure with single wide (25 nm) quantum well under applied electric bias. Two-photon correlations were measured with the use of a classical Hanbury Brown - Twiss intensity interferometer (time resolution ~0.4 ns). Photon "bunching" has been observed near the Bose condensation threshold of dipolar excitons determined by the appearance of a narrow luminescence line of exciton condensate at optical pumping increase. The two-photon correlation function shows super-poissonian distribution at time scales of system coherence (

We demonstrate that the data are consistent with the theory of crystallization of the ions in the interior of white dwarf stars and provide the first empirical evidence that the phase transition is first order: latent heat is released in the process of crystallization as predicted by van Horn (1968). We outline how this data can be used to observationally constrain the value of Gamma = E_{Coulomb}/E_{thermal} near the onset of crystallization, the central carbon/oxygen abundance, and the importance of phase separation.

An assessment of the contribution to Australian string pedagogy and performance of Jan Sedivka
Creators: name: Phillips, Marina Louise
Publisher: name: University Of Tasmania
Year: 2023

description: Violin performance and pedagogy have been a central thread in my life for many years. The art of communicating something you love to others, is a very special occupation. I became interested in the work of Jan Sedivka as a young student violinist in Western Australia, where the knowledge of the existence of a 'great old master' Jiving in _Tasmania was in the hack uf my mind. My first enc_ounter with Sedivka occurred when I participated in one of his master classes. During this class a contemporary of mine performed the first movement of the Mendelssohn Violin Concerto and I heard my first Sedivkaism \the worse the octaves sound the closer they are to being in tune.\" I found this thought most amusing and heartening at the time! I once again encountered 'the old man' at a Spring Chamber Music Camp where three of Perth's leading string teachers plus Sedivka were engaged in a heated discussion about the use of the right-hand fingers in the performance of unaccompanied Bach. At the time Sedivka and his former student Peter Exton argued for the negative team while Gregory Baron and Alan Bonds worked for the affirmative. (Readers note; Sedivka would have been just as happy and capable to argue for the other side if the opportunity had presented itself!) In 1988 Peter Exton became my principal violin teacher and for two years 'the boss' oversaw my lessons with his unsmiling photographic front. In 1996 at the suggestion of Peter I travelled to Melbourne to meet Jan Sedivka and again encountered that generous alternative argumentative grey-haired gentleman who was so dear to the string fraternity of Australia. The ideas he presented were new challenging and seemingly unconventional. I also discovered a teacher whose methods intrigued me; he did not say what one would necessarily expect or desire. The experiences described above led me to the idea that I would like to attempt to unravel the truths of this teacher and in 1998 I moved to Tasmania to study with 'the master' and to commence my doctorate. My interest in Sedivka's pedagogical style was motivated further by the glaring differences in playing style between violinists in Western Australia and in Tasmania. I also could not believe how many players of a high calibre there were in Hobart in relation to the size of the city and how these players exhibited a technical and musical ease of playing. The phrases of the Tasmanian string players seemed to breathe and to have a natural ebb and flow. I was also very aware however of the immense individuality of each player in terms of sound technique and physical set-up. The combination of the factors thus described created a set of unanswered questions that became catalysJs for my interest_ and the doctoral project presented here was born."

description: In order to meet the growing concerns of society horticultural growers have to adopt reduction techniques for pesticides and nutrients. Based on a theoretical framework the adoption of these techniques is influenced by personal and business characteristics and communication behaviour. Data were collected at 248 professional horticultural holdings, resulting in fifteen explanatory variables and one dependent variable representing the environmental score, calculated on the basis of the number of the applied reduction techniques. By means of a categorical principal component analysis the 15 explanatory variables were reduced to 5 independent dimensions. Regression analysis resulted in a significant influence of the dimension â€˜attitude towards openness and large business sizeâ€™ on the environmental score. The same result was obtained for a regression analysis for the sub sector vegetables. For the sub sector ornamental plants the dimension â€˜attitude towards risk and environmental sound productionâ€™ was significant. For fruit production no relations were found.

description: We apply a unitary approach together with a set of hidden-gauge Lagrangians to study the vector-vector interaction. We study the case of the $ρ$($ω$)$D^*$ interaction within the model. In $I=1/2$ we get strong enough attraction to bind the system. Concretely, we get one resonance for each spin $J=0,1,2$. For J=1 and 2 these resonances can be easily identified with the $D^*(2460)$ and $D^*(2640)$. Whereas the state for J=0 with mass $M\sim2600$ MeV is a prediction of the model. In $I=3/2$ we get a repulsive interaction and hence no exotic dynamically generated states.

description: For many developing countries, the agricultural sector is still the main employer, especially for women, and particularly in sub-Saharan Africa. The causes of poverty are complex and often superficially understood. As a result, efforts to resolve these problems are frequently fragmented and development interventions become severely limited in focus and reach. The development of the agricultural sector can ensure integration of the regionâ€™s economies and the resultant upliftment of rural communities. Market access seems to be one of the most limiting factors which have been identified that is hindering growth in rural agriculture. Factors influencing market access are lack of information, training and extension services, tenure systems, transport and credit. Resolving the South African problem requires a concerted, holistic, innovative and integrated approach through partnerships between the civic, public and private sectors. The market access problem should be addressed based on linkages between the small producers and markets by addressing the constraints. The fact is recognise that small farmers do not exist in isolation but is part of a large market system. Interventions are therefore well grounded in understanding the business development service markets within which small producers operate, as well as enhancing win-win linkages between rural-based service providers and small producers.

description: The study is based on a detailed analysis of seven case study farms to assess the economic contribution of the Entry Level Scheme (ELS) to farm income. Theoretically agri-environment schemes should not make a positive contribution to farm income. On each case study farm the financial impact of participation in ELS was assessed using a conventional partial budgeting methodology. The actual income foregone figures from the case study farms were then compared with the theoretical figures produced by DEFRA. The study established that there is a substantial difference between the actual costs and income foregone and those assumed by DEFRA. The farms were therefore able to profit from their ELS agreements and it did make a positive contribution to farm income. The study raises important issues about the principles involved, in particular the use of actual and notional costs and the overlap between agri-environment requirements and voluntary unpaid measures undertaken by farmers ex ante. The study also addresses whether it is only those farmers who are able to profit who will enter the scheme.

description: In parallel with other applied disciplines, education in Farm Management needs to combine the exposure of students to theoretical frameworks as well as to situations where practically applied knowledge can be experienced and explored. Over the past 33 years, programs at Orange Agricultural College have used farm and industry visits as a strategy to enhance formal classroom activities in Farm Management education. Carefully designed tours enable students to observe, interview and listen to the experiences of practising managers in a manner that enables them to build awareness of applied management in a variety of â€œexemplaryâ€ farming and industry situations. Such engagement assists the student in their personal learning process as they reflect on what they see happening, how it happened and why. This paper builds on a broader paper that initially explored how constructive alignment between curriculum, assessment and tour design is critical in achieving learning outcomes. From this base, it focuses particularly on research that has sought to capture the experience gained through Farm Management programs over the past 3 decades at Orange Agricultural College. Emphasis is placed on combining learning outcomes for the student with the role of academics involved and with the industry co-operator visited and the early approach of Information Gathering is contrasted to the current best practice of Student Authorship. Such a tripartite connection enhances the conditions for creating more meaningful learning experiences and, over time, builds a richer sense of community for all involved.

description: Quality of Life is influenced by a number of key influential factors (happiness; family life; health, and finances). The current literature pertaining to these Quality of Life factors were reviewed to examine if any variation existed among farm families experiencing disability relative to the general farm population. Almost 10% of Irish farm families experience disability. The principal cause of disability among farm families is often health-related. While farm families feel that farming is a good way of life, the experience of disability can add considerable strain on family life and relationships. Farm families experiencing disability recorded lower family farm incomes and lower participation in off-farm employment. Service and support provision was a concern for farm families experiencing disability. It is imperative the restrictive nature of disability is minimised for farm families. Improved service/support provisions for farm families reporting disability are required for this to be achieved.

Genotypic and phenotypic analysis of muscles from dystrophic - normal mouse chimeras
Creators: name: Peterson, Alan Clarke
Publisher: name: University of British Columbia
Year: 2011

description: 1. Artificial chimeric mice, mosaic for muscular dystrophic (dy[sup 2J] /dy[sup 2J]) and normal (SWV +/+) genotypes were successfully produced. 2. These chimeric mice demonstrated no clinical features of the dystrophic condition. 3. A maximum stimulated twitch analysis of the anterior tibialis muscles of these chimeras also revealed no functional deficiences characteristic of the dystrophic condition. 4. The electrophoretic phenotype of Mod-1 (malic enzyme) was resolved with a high voltage micro starch gel system and a quantitative analysis was developed to detect and estimate the relative muscle fiber nuclear mosaicism in single muscles from the chimeras. The measured activity of the 5 bands of the Mod-1 hetero-zygote phenotype was observed to be different from the expected ratio of 1:4:6:4:1 previously reported. 5. The presence of genetically dystrophic nuclei was detected in the majority of chimera muscles examined. The overall content of (dy[sup 2J] /dy[sup 2J]) nuclei from all the muscle samples examined was estimated to be 58%. This indicated that genetically dystrophic cells contribute normally to muscle morphogenesis and that genetically dystrophic muscle fiber nuclei suffer no specific degeneration in this artificial mosaic environment. 6. Within single chimeras the composition of muscles varied extensively. Individual muscles of both normal and primarily dystrophic genetic composition were detected. 7. Histological analysis of samples of anterior tibialis muscles, prepared in 1 u thick plastic sections, was undertaken to determine if any preclinical muscle degeneration had taken place. These muscles had essentially normal phenotypes. 8. Examples of muscles with primarily dystrophic genotypic composition and remarkably normal histological phenotype were revealed. Conversely, muscles with no detectable dystrophic composition were observed to have foci of degeneration characteristic of muscular dystrophy. These results, although not extensive, are suggestive that the muscle degeneration observed in dystrophic (dy[sup 2J] /dy[sup 2J]) mice is secondary to a primary lesion residing outside the muscle fiber proper. 9. The possible similarities between these artificial cellular mosaics and a human X-linked genetic mosaic, the heterozygous female for Duchenne dystrophy, are presented. 10. The results of these studies were discussed in terms of the application of chimeric mice in the delineation of the primary lesion in mouse muscular dystrophy.

description: Within the framework of the improved isospin dependent quantum molecular dynamics (ImIQMD) model, the pion emission in heavy-ion collisions in the region 1 A GeV is investigated systematically, in which the pion is considered to be mainly produced by the decay of resonances $\triangle$(1232) and N*(1440). The in-medium dependence and Coulomb effects of the pion production are included in the calculation. Total pion multiplicity and $π^{-}/π^{+}$ yields are calculated for the reaction $^{197}$Au+$^{197}$Au in central collisions for selected Skyrme parameters SkP, SLy6, Ska, SIII and compared them with the measured data by the FOPI collaboration.

description: One of the five key science projects for the Square Kilometre Array (SKA) is "The Origin and Evolution of Cosmic Magnetism", in which radio polarimetry will be used to reveal what cosmic magnets look like and what role they have played in the evolving Universe. Many of the SKA prototypes now being built are also targeting magnetic fields and polarimetry as key science areas. Here I review the prospects for innovative new polarimetry and Faraday rotation experiments with forthcoming facilities such as ASKAP, LOFAR, the ATA, the EVLA, and ultimately the SKA. Sensitive wide-field polarisation surveys with these telescopes will provide a dramatic new view of magnetic fields in the Milky Way, in nearby galaxies and clusters, and in the high-redshift Universe.

PR - A2 Milk, Farmer Decisions, And Risk Management
Creators: name: Woodford, Keith
Publisher: name: Unknown

Subjects: subject: Risk and Uncertainty
subject: A2 milk
subject: A2 beta-casein
subject: health

description: Approximately 500 New Zealand (NZ) dairy farmers are converting their herds to eliminate production of A1 beta-casein within the milk. The alternative casein is A2 beta-casein, and the associated milk is known as A2 milk. A2 milk can be considered the original milk before a mutation affected some antecedents of modern European breeds. A1 beta-casein and its derivative beta-casomorphin7 (BCM7) have been implicated in numerous health issues including Type 1 diabetes, heart disease and autism. There are now more than 100 relevant papers in peer reviewed journals. The broader NZ herd is also drifting away from A1 beta-casein production due to a serendipitous association between genetic merit as measured in NZ and A2 beta-casein. There is no evidence of this occurring in other countries. The farmer decisions can be structured using concepts of risk management and decision theory. However analysis is complicated by uncertainty as to future premiums/discounts associated with A2/A1 milk. Outside of NZ most farmers know nothing about the issue.

description: Direct marketing by farmers is considered to be one of the most promising new areas of activity within a diversified rural economy and has received significant support in recent EU CAP reforms. It has yet to be revealed whether such activities can be profitable and sustainable over the long term, particularly in Less Favoured Areas (LFAs) where disadvantageous production conditions and a reduction in headage payments mean that livestock farmers face particularly stern challenges. In this paper, a farm-based analysis is conducted in the county of Northumberland in North East England. Semi-structured interviews were conducted with two LFA livestock farmers who have diversified into direct marketing activities. Our findings suggest that in these cases direct marketing activities have become more lucrative than the conventional sources of income available to their neighbours through wholesale markets.

Fatigue, watchkeeping and accidents : a content analysis of incidents at sea reports
Creators: name: Phillips, RJB
Publisher: name: University Of Tasmania
Year: 2023

description: The profession of seafaring involves rest and sleep in a 24-hour-a-day work environment; obtaining sufficient sleep under such conditions is often difficult, and sleep loss and the need for sleep is often related to fatigue and contributory to accidents. Maritime incident reports form a rich source of human performance data with high face validity, however fatigue as contributory to human error is elusive, and direct evidence of accident causation is hard to come by. In Australia, the Australian Transportation Safety Board has responsibility to investigate incidents at sea. The present study aimed to identify evidence of time of day and sleep deprivation as factors that appear contributory to fatigue in \Incidents at Sea\" reports. Both quantitative and qualitative analyses of the text of these reports were conducted using NUDIST¬¨vÜ categories were developed and patterns identified. The effect of time of day was identified from analysis of the conclusions of 100 consecutive reports to determine the nature and distribution of behaviours associated with fatigue. Collisions and groundings were more prevalent during the early morning watches. Behaviours consistent with fatigue were identified categorised and described for different times of the day with deficits in alertness predominating in the early morning watches and deficits in information processing predominating in the afternoon watches. The contribution of sleep deprivation and its relationship with fatigue and accidents was identified from analysis of the full text of 44 reports which incorporated three levels of association of sleep with accident causation. The highest level establishes either being asleep or being sleep deprived as causal to an accident. At an intermediate level reference to the conflicting pressures -' of work and sleep suggests a work environment that is not conducive to obtaining sufficient sleep and accident investigators were usually unable to link the watchkeeping environment with fatigue as a contributing factor. At the lowest level of association reference is made to the integrated nature of sleeping and work on board. Finally a model illustrating the relationships between sleep deprivation time of day and fatigue behaviours in the maritime setting was proposed providing accident investigators with a tool to assist with the identification of fatigue in their analyses of maritime incidents. In addition this model would be useful in the education of maritime administrators and policy developers shipping companies and seafarers."
Lorentz Invariance Violation from Gamma-Ray Bursts

description: Lorentz invariance violation (LV) is examined through the time delay between high-energy and low-energy photons in gamma-ray bursts (GRBs). Previous studies determined the LV energy scale as $E_{\rm LV} \simeq 3.60 \times 10^{17}$~GeV using Fermi Gamma-ray Space Telescope (FGST) data. This study updates the time-delay model and reaffirms these findings with new observations. High-energy photons from GRBs at GeV and TeV bands are analyzed, including the 99.3 GeV photon from GRB 221009A (FGST), the 1.07 TeV photon from GRB 190114C (MAGIC), and the 12.2 TeV photon from GRB 221009A (LHAASO). Our analysis, in conjunction with previous data, consistently shows that high-energy photons are emitted earlier than low-energy photons at the source. By evaluating 17 high-energy photons from 10 GRBs observed by FGST, MAGIC, and LHAASO, we estimate the LV energy scale to be $E_{\rm LV} \simeq 3.00 \times 10^{17}$ GeV. The null hypothesis of dispersion-free vacuum $E=pc$ (or, equivalently, the constant light-speed $v_γ=c$) is rejected at a significance level of 3.1$σ$ or higher.

Interference and coding processes in verbal and visual short-term memory
Creators: name: Ternes, Willi
Publisher: name: University of British Columbia
Year: 2011

description: A detailed evaluation of short-term verbal and visual coding efficiency as a function of Interpolated activities, varying along the dimensions of attention and similarity, was undertaken in this research. The results show that retention losses due to attention demand changes are comparable in verbal and visual coding conditions, regardless of the modality of the Interpolated activity. In addition, retention losses are larger when the same modality is involved in processing the stimulus and Interpolated task. Retention losses are Interpreted as demonstrating a clear separation of short-term losses due to: a) attention diversion; and b) direct Interference, with attention diversion accounting for a larger part of total retention losses. The data further suggest that the maintenance of Information In verbal and visual STS relies to a large extent on the availability of the common central processing capacity, with modality specific coding processes determining the most appropriate coding mode for a given stimulus situation.

description: Renewable resources are of importance in our modern society due to their positive effects on agriculture, the environment and the economy. To support renewable energy from biomass the EU promotes the cultivation of energy crops. This creates alternative income sources for farmers as primary or energy producers and strengthens added value and employment. For the analysis a model is developed to assess the potential impacts of energy crop production on cropping activities. A basic quadratic version of PMP is used to maximize total gross margin in two regions, which allows one to simulate farmers` behavior under different conditions. Different scenarios show, that the bio-energy boom partially contributes to crop substitution effects. Potential energy crops like rye, rape seed or silage maize are more profitable. This has an impact on crop rotations because less profitable crops are substituted. However, these tendencies approach a limit in terms of limited area and crop rotational aspects.

FAIR Data Stewardship - Data sharing, archiving and publishing
Creators: name: Staiger, Christine
Publisher: name: Zenodo
Year: 2019
Subjects: Data Life Cycle, FAIR, Data management, Data stewardship, data repositories, data sharing, data publication

description: In this workshop we focus on three aspects of FAIR data stewardship: Data sharing, publishing and archiving. Many scientists have an insufficient overview over data services, roles and their responsibilities towards safe data sharing, archiving and publishing. Shedding light on these roles helps to improve quality of archived and published data and metadata. Moreover, more information on safe data sharing of potentially sensitive data is needed in the scientific communities.

The workshop introduces the concepts and gives hands-on experience with tools which allow safe data sharing, archiving and publishing on example services. Moreover, participants of the workshop explore together different roles which are defined around data publication and how responsibilities towards data are distributed. The course does not require any prior knowledge.
