Battery and cell testing at NASA. Marshall Space Flight Center

An overview covering the ten cell/battery tests ongoing at MSFC are presented. The presentation is not intended to give specific test results on any test. The purpose and related program that applies to each test is acknowledged. Except for the Combined Release and Radiation Effects Satellite (CRRES), all are energy-stored and retrieval devices at low earth orbit (LEO) cycles

The Jury System in Contemporary Ireland: In the Shadow of a Troubled Past

Jackson et al discuss the distinctive features of criminal trial by jury in Ireland, both north and south, to explain how the jury continues to survive within modern Ireland and how it also has managed to decline in significance

The Signal Data Explorer: A high performance Grid based signal search tool for use in distributed diagnostic applications

We describe a high performance Grid based signal search tool for distributed diagnostic applications developed in conjunction with Rolls-Royce plc for civil aero engine condition monitoring applications. With the introduction of advanced monitoring technology into engineering systems, healthcare, etc., the associated diagnostic processes are increasingly required to handle and consider vast amounts of data. An exemplar of such a diagnosis process was developed during the DAME project, which built a proof of concept demonstrator to assist in the enhanced diagnosis and prognosis of aero-engine conditions. In particular it has shown the utility of an interactive viewing and high performance distributed search tool (the Signal Data Explorer) in the aero-engine diagnostic process. The viewing and search techniques are equally applicable to other domains. The Signal Data Explorer and search services have been demonstrated on the Worldwide Universities Network to search distributed databases of electrocardiograph data

Monopolizing force?: police legitimacy and public attitudes towards the acceptability of violence

Why do people believe that violence is acceptable? In this paper we study people’s normative beliefs about the acceptability of violence to achieve social control (as a substitute for the police, for self-protection and the resolution of disputes) and social change (through violent protests and acts to achieve political goals). Addressing attitudes towards violence among young men from various ethnic minority communities in London, we find that procedural justice is strongly correlated with police legitimacy, and that positive judgments about police legitimacy are associated with more negative views about the use of violence. We conclude with the idea that police legitimacy has an additional, hitherto unrecognized, empirical property – by constituting the belief that the police monopolise rightful force in society, legitimacy has a ‘crowding out’ effect on positive views of private violence

Instant messaging implications in the transition from a private consumer activity to a communication tool for business

Used to communicate important information and provide contact outside of lectures to great effect, email has emerged as the communication medium of choice. However, Instant Messaging is fast emerging as a favourable world-wide method of communication with its interactive nature and appealing user interfaces. However, can it be as effective within the organisation and more importantly the university as the now established email? This research paper will explore how Instant Messaging is advancing from a private consumer activity to a tool capable of improving communication within the university and organisations. Through the development of a controlled experiment the paper examines the way in which Instant Messaging is being adopted and how it compares to other forms of communication, including its associated interrupt recovery time. The paper also looks at the extent of disruption that Instant Messaging has on users and how users reacted differently to new messages via different notification settings

Legitimacy and procedural justice in prisons

All social situations are ‘ordered’ in some way, comprising a constantly changing set of relationships that establish the structure within which human action occurs. In many circumstances this order is hidden, even ephemeral; we are barely aware of its presence. But this is not the case in prisons. Social order in prison is in many ways highly visible: it is established and managed by the omnipresent rules that govern prison life. In large part these rules are oriented toward reproducing the extant regime. They lay down apparently strict criteria for what constitutes order and what is to be done if it is breached. But what is meant by order in prison? Most socia

Augustana Seniors Fall 1884: William Mering Reck

William Mering Reck was a senior at Augustana College, Rock Island, Illinois, in the fall of 1884. His name appears in the college catalog of 1884 – 1885, along with his birthplace, the year of his birth, and a few other facts. From this start, we researched the genealogy and family history of Reck. This paper contains a short biography of Reck, a report on his ancestors, a report on his descendants, and some open questions for further research

Productivity pathways: climate-adjusted production frontiers for the Australian broadacre cropping industry

This study introduces two advances to the aggregate productivity index methodology typically employed by ABARES. First, it accounts for the effects of climate variability on measured productivity by matching spatial climate data to individual farms in the ABARES farm surveys database. Second, a farm-level production frontier estimation technique is employed to facilitate the decomposition of productivity change into several key components, including technical change and technical efficiency change. The study makes use of farm-level data from the ABARES Australian agricultural and grazing industries survey database. An unbalanced panel dataset is constructed containing 13 430 observations (4255 farms) over the period 1977–78 to 2007–08. Spatial climate data, including winter and summer seasonal rainfall and average maximum and minimum temperatures, were obtained via the Australian Water Availability Project. These data were mapped to individual farms using Geographic Information System methods. The study employed stochastic frontier analysis methods to estimate a production frontier with time varying technical efficiency effects of the form proposed by Battese and Coelli (1992). Production frontiers are estimated for each of the three major Grains Research and Development Corporation regions: southern, northern and western. Selected climate variables are shown to display a high degree of explanatory power over farm output. The results confirm that deterioration in average climate conditions has contributed significantly to the decline in estimated productivity over the post-2000 period. Technical change is shown to be the primary driver of productivity growth in the industry in the long run, offset by a gradual decline in technical efficiency. After controlling for climate variability, a gradual decline in the rate of technical change is still observed.Productivity Analysis,
