Topographic and thermal mapping of volcanic terrain using AVTIS ground-based 94-GHz dual-mode radar/radiometric imager

The All-Weather Volcano Topography Imaging Sensor remote sensing instrument is a custom-built millimeter-wave (MMW) sensor that has been developed as a practical field tool for remote sensing of volcanic terrain at active lava domes. The portable instrument combines active and passive MMW measurements to record topographic and thermal data in almost all weather conditions from ground-based survey points. We describe how the instrument is deployed in the field, the quality of the primary ranging and radiometric measurements, and the postprocessing techniques used to derive the geophysical products of the target terrain, surface temperature, and reflectivity. By comparison of changing topography, we estimate the volume change and the lava extrusion rate. Validation of the MMW radiometry is also presented by quantitative comparison with coincident infrared thermal imagery.

Measurements of stratospheric ozone at a mid-latitude observing station Valentia, Ireland (51.94° N, 10.25° W), using ground-based and ozonesonde observations from 1994 to 2009

Sixteen years (1994 – 2009) of ozone profiling by ozonesondes at Valentia Meteorological and Geophysical Observatory, Ireland (51.94° N, 10.23° W) along with a co-located MkIV Brewer spectrophotometer for the period 1993–2009 are analyzed. Simple and multiple linear regression methods are used to infer the recent trend, if any, in stratospheric column ozone over the station. The decadal trend from 1994 to 2010 is also calculated from the monthly mean data of Brewer and column ozone data derived from satellite observations. Both of these show a 1.5 % increase per decade during this period with an uncertainty of about ±0.25 %. Monthly mean data for March show a much stronger trend of ~ 4.8 % increase per decade for both ozonesonde and Brewer data. The ozone profile is divided between three vertical slots of 0–15 km, 15–26 km, and 26 km to the top of the atmosphere and a 11-year running average is calculated. Ozone values for the month of March only are observed to increase at each level with a maximum change of +9.2 ± 3.2 % per decade (between years 1994 and 2009) being observed in the vertical region from 15 to 26 km. In the tropospheric region from 0 to 15 km, the trend is positive but with a poor statistical significance. However, for the top level of above 26 km the trend is significantly positive at about 4 % per decade. The March integrated ozonesonde column ozone during this period is found to increase at a rate of ~6.6 % per decade compared with the Brewer and satellite positive trends of ~5 % per decade.

Game geek's goss: linguistic creativity in young males within an online university forum (94/\/\3 933k’5 9055oneone)

In this paper the authors explore the use and adaptation of a language specifically developed for, and by, a community of young people who play computer games. Leet speak or 1337 5p34k, the language used by the participants in this study, incorporates symbols and numbers as substitutes for the letters contained in words. Described by the group as an ‘elite’ language or ‘leet speak’, the authors’ interest was captured by the derisive and ironic use of the language in an online forum for a tertiary first year unit of study. Rather than merely defining its participants within an elite cultural boundary, ‘leet speak’ is utilised ironically to unearth ‘wannabees’ (those seeking entrance and acceptance into the game world, generally 12 –16 year olds). Of particular fascination to the authors was that despite the clear self- demarcation of the group from the users of ‘leet speak’, and their insistence on its use solely by ‘newbs and wannabees’, the group continued to use the language to communicate with each other online. In this research, language defines the cultural group of games technology students in terms of the group’s continual subversion of the language’s very foundations whilst still using it to communicate. Perhaps most interesting was the group’s nonchalant admission that they perceived this to be the function of all languages ‘all languages are created purely for communication so dont [sic] have a cry about ppl been [sic] lazy’.

Letting go without a fight : decolonization, democracy and war, 1900-94

Does the type of regime really make no difference to the likelihood of violent conflict over basic issues of stateness such as separatism and decolonization? Can democratic peace theory be successfully applied when dealing with the national identity or stateness question? This article extends the application of the democratic peace to the process of decolonization. It examines conflict between imperial states and their colonies during the process of decolonization and investigates the question of whether democracy affects the likelihood of conflict. The central finding is that, contrary to the implications of some prominent theories of state formation and democracy, democratic imperial states are significantly less likely to go to war with their colonial possessions in the process of achieving independence. Further, the authors find only a monadic, not dyadic, democratic peace effect. The regime type of the colony does not have a significant effect on the likelihood of war. It is the nature of the regime of imperial states, rather than that of colonies, that is a significant factor. In addition, the predominant source of this effect appears to be the institutional constraints placed on executive action within democracies, rather than the influence of mass politics or the effects of political competition. Regarding power-related factors, power parity between sovereign and colony makes conflict more likely (a colonial power-transition effect), but imperial decline actually makes war with colonies less likely. Sensitivity analysis reveals that a number of other hypothesized effects cannot find robust support. Simulations are used to assess the magnitude of the effect of regime type pre- and post-independence. Overall, the article contributes to theory development by investigating different institutional aspects of democracy and by distinguishing monadic and dyadic effects.

Health system costs of diseases and injury in Australia 1993-94 : an analysis of costs, service use and mortality for major disease and injury groups

Provides a systematic analysis of the health system use and costs associated with specific disease and injury groups in Australia in 1993-94. The estimates are presented in a consistent format and are derived using a methodology that ensures the results add across disease, age and sex groups to total Australian health expenditures for 1993-94.

Elementos econômicos para uma revisão da lei 8884/94

O objetivo deste projeto é realizar uma contribuição para um futuro aperfeiçoamento da legislação antitruste brasileira, cuja principal peça legal é a Lei 8884/94. A pesquisa contém três partes. A primeira contextualiza a Lei 8884 no processo de evolução recente da economia brasileira, assinalando sua crescente importância a partir de meados dos anos noventa com a estabilização dos preços. A segunda organiza, para um conjunto selecionado de temas, a discussão teórica e a jurisprudência administrativa existentes. A terceira sugere aperfeiçoamentos tópicos, incluindo, quando possível, uma proposta de redação alternativa do texto legal.
