This paper takes a large-scale social perspective in describing a national project in Australia that was premised on local school communities working together and contributing ideas for the benefit of their students, and potentially, the whole country. The project was intended to improve schools’ capacity for educating boys, and in the long-term, the learning outcomes of under-performing boys, using evidence-based and action research methods. It was supported by the web spaces and tools of the National Quality Schooling Framework and Think.com. This paper emphasises the structures and processes teachers engaged in while building knowledge through their daily work, where the resulting ideas became the property of the whole community. Analyses focus on the extent to which an underlying social structure for knowledge building developed in various parts of the nation during the project, making it possible to characterize a process for innovations in education with commitment to continual idea improvement. Résumé Le présent article adopte une perspective sociale à grande échelle pour décrire un projet national en Australie fondé sur la collaboration des communautés scolaires locales et leur contribution d’idées au bénéfice de leurs élèves et, éventuellement, de l’ensemble du pays. Le projet avait pour but de rendre les écoles plus aptes à éduquer les garçons et, à long terme, d’améliorer les résultats d’apprentissage des garçons qui sous-performent à l’aide de méthodes de recherche-action fondées sur des données probantes. Il a bénéficié du soutien des espaces et des outils Web du National Quality Schooling Framework et de Think.com. Le présent article met l’accent sur les structures et les processus que les enseignants ont utilisés dans leur travail quotidien pour la coélaboration de connaissances; les idées qui en ont résulté sont par la suite devenues la propriété de l’ensemble de la communauté. Les analyses portent principalement sur la mesure dans laquelle une structure sociale sous-jacente de coélaboration des connaissances s’est développée en différents endroits de la nation au cours du projet, ce qui rend possible la caractérisation d’un processus d’innovation en éducation avec un engagement envers l’amélioration continue.

Ego Depletion

Ego depletion has been successfully replicated in hundreds of studies. Yet the most recent large-scale Registered Replication Reports (RRR), comprising thousands of participants, have yielded disappointingly small effects, sometimes even failing to reach statistical significance. Although these results may seem surprising, in the present article I suggest that they are perfectly consistent with a long-term decline in the size of the depletion effects that can be traced back to at least 10 years ago, well before any of the RRR on ego depletion were conceived. The decline seems to be at least partly due to a parallel trend toward publishing better and less biased research.

Abstract. Ego depletion has been successfully replicated in hundreds of studies. Yet the most recent large-scale Registered Replication Reports (RRR), comprising thousands of participants, have yielded disappointingly small effects, sometimes even failing to reach statistical significance. Although these results may seem surprising, in the present article I suggest that they are perfectly consistent with a long-term decline in the size of the depletion effects that can be traced back to at least 10 years ago, well before any of the RRR on ego depletion were conceived. The decline seems to be at least partly due to a parallel trend toward publishing better and less biased research.

Abstract Daily work in molecular biology presently depends on a large number of computational tools. An in-depth, large-scale study of that ‘ecosystem’ of Web tools, its characteristics, interconnectivity, patterns of usage/citation, temporal evolution and rate of decay is crucial for understanding the forces that shape it and for informing initiatives aimed at its funding, long-term maintenance and improvement. In particular, the long-term maintenance of these tools is compromised because of their specific development model. Hundreds of published studies become irreproducible de facto, as the software tools used to conduct them become unavailable. In this study, we present a large-scale survey of >5400 publications describing Web servers within the two main bibliographic resources for disseminating new software developments in molecular biology. For all these servers, we studied their citation patterns, the subjects they address, their citation networks and the temporal evolution of these factors. We also analysed how these factors affect the availability of these servers (whether they are alive). Our results show that this ecosystem of tools is highly interconnected and adapts to the ‘trendy’ subjects in every moment. The servers present characteristic temporal patterns of citation/usage, and there is a worrying rate of server ‘death’, which is influenced by factors such as the server popularity and the institutions that hosts it. These results can inform initiatives aimed at the long-term maintenance of these resources.

Abstract. The summer flood of 2013 set a new record for large-scale floods in Germany for at least the last 60 years. In this paper we analyse the key hydro-meteorological factors using extreme value statistics as well as aggregated severity indices. For the long-term classification of the recent flood we draw comparisons to a set of past large-scale flood events in Germany, notably the high-impact summer floods from August 2002 and July 1954. Our analysis shows that the combination of extreme initial wetness at the national scale – caused by a pronounced precipitation anomaly in the month of May 2013 – and strong, but not extraordinary event precipitation were the key drivers for this exceptional flood event. This provides additional insights into the importance of catchment wetness for high return period floods on a large scale. The database compiled and the methodological developments provide a consistent framework for the rapid evaluation of future floods.

<p>This paper investigates CSCW aspects of large-scale technical projects based on a case study of a specific Danish engineering company and uncovers challenges to CSCW aplications in this setting. The company is responsible for management and supervision of one of the worlds largest tunnel/bridge construction projects. Our primary aim is to determine requirements on CSCW as they unfold in this concrete setting as opposed to survey and laboratory investigations. The requirements provide feedback to product development both on specific functionality and as a long term vision for CSCW in such settings.</p><p>The initial qualitative analysis identified a number of bottlenecks in daily work, where support for cooperation is needed. Examples of bottlenecks are: sharing materials, issuing tasks, and keeping track of task status. Grounded in the analysis, cooperative design workshops based on scenanos of future work situations were established to investigate the potential of different CSCW technologies in this setting. In the workshops, mock-ups and prototypes were used to support end-users in assessing CSCW technologies based on con crete, hands-on experiences. The workshops uncovered several challenges. First, support for sharing materials would require a huge body of diverse materials to be integrated, for example into a hypermedia network. Second, daily work tasks are event driven and plans change too rapidly for people to register them on a computer. Finally, tasks are closely coupled to materials being processed thus a coordination tool should integrate facilities for managing materials.</p>

The author of this article attempts to trace the evolution of the British memory concerning the Battle of Trafalgar, which predetermined the long-term dominance of Britain on the seas. Almost immediately after receiving the first news of Trafalgar and the death of H. Nelson, large-scale ceremonies began which were associated with a grand victory on the national scale. By the beginning of the twentieth century, the era of the “living memory” of Trafalgar was over. At the same time, radical changes in the balance of geopolitical forces made the British think again and again about Trafalgar. Even though the First and Second World Wars pushed the images of glorious victories at sea in the distant era of the Napoleonic wars into the background in the minds of the British, during the 150th anniversary of Trafalgar, the British military and state elite tried to revive the glorious images of the distant past, using “historical resources” to maintain the national spirit. The dynamics in the awareness of the British elite and the public of the importance of the anniversary was remarkable as it evolved from semi-indifference to events of the widest scope. Fifty years later, London made another attempt to use the anniversary of Trafalgar to raise patriotic sentiments among the British youth, as well as strengthen the military-strategic partnership with its allies. At the same time, analysts noted the progressive loss of the fundamental moments for the national identity of the British. The author concludes that the perception of the image of Trafalgar by the British has passed a difficult path over 200 years, which demonstrated a variant of the development of “living memory”, which, despite all attempts to preserve the energy and direction of the original impulse, is being inevitably replaced by what is now commonly called commemoration.

Abstract. The summer flood 2013 sets a new record for large-scale floods in Germany since at least 1952. In this paper we analyze the key hydro-meteorological factors using extreme value statistics as well as aggregated severity indices. For the long-term classification of the recent flood we draw comparisons to a set of past large-scale flood events in Germany, notably the high impact summer floods from August 2002 and July 1954. Our analysis shows that the combination of extreme initial wetness at the national scale – caused by a pronounced precipitation anomaly in the month of May 2013 – and strong, but not extraordinary event precipitation were the key drivers for this exceptional flood event. This provides new insights to the importance of antecedent soil moisture for high return period floods on a large-scale. The data base compiled and the methodological developments provide a consistent framework for the rapid evaluation of future floods.

AbstractThe large-scale coronal structures observed during the sporadically visible solar eclipses were compared with the numerically extrapolated field-line structures of coronal magnetic field. A characteristic relationship between the observed structures of coronal plasma and the magnetic field line configurations was determined. The long-term evolution of large scale coronal structures inferred from photospheric magnetic observations in the course of 11- and 22-year solar cycles is described.Some known parameters, such as the source surface radius, or coronal rotation rate are discussed and actually interpreted. A relation between the large-scale photospheric magnetic field evolution and the coronal structure rearrangement is demonstrated.
