The first real-time worldwide ionospheric predictions network: an advance in support of spaceborne experimentation, on-line model validation, and space weather

We report on the first realtime ionospheric predictions network and its capabilities to ingest a global database and forecast F-layer characteristics and "in situ" electron densities along the track of an orbiting spacecraft. A global network of ionosonde stations reported around-the-clock observations of F-region heights and densities, and an on-line library of models provided forecasting capabilities. Each model was tested against the incoming data; relative accuracies were intercompared to determine the best overall fit to the prevailing conditions; and the best-fit model was used to predict ionospheric conditions on an orbit-to-orbit basis for the 12-hour period following a twice-daily model test and validation procedure. It was found that the best-fit model often provided averaged (i.e., climatologically-based) accuracies better than 5% in predicting the heights and critical frequencies of the F-region peaks in the latitudinal domain of the TSS-1R flight path. There was a sharp contrast however, in model-measurement comparisons involving predictions of actual, unaveraged, along-track densities at the 295 km orbital altitude of TSS-1R In this case, extrema in the first-principle models varied by as much as an order of magnitude in density predictions, and the best-fit models were found to disagree with the "in situ" observations of Ne by as much as 140%. The discrepancies are interpreted as a manifestation of difficulties in accurately and self-consistently modeling the external controls of solar and magnetospheric inputs and the spatial and temporal variabilities in electric fields, thermospheric winds, plasmaspheric fluxes, and chemistry.

The neoliberal way of war: a critical analysis of contemporary British security in policy and practice.

Dominant paradigms of causal explanation for why and how Western liberal-democracies go to war in the post-Cold War era remain versions of the 'liberal peace' or 'democratic peace' thesis. Yet such explanations have been shown to rest upon deeply problematic epistemological and methodological assumptions. Of equal importance, however, is the failure of these dominant paradigms to account for the 'neoliberal revolution' that has gripped Western liberal-democracies since the 1970s. The transition from liberalism to neoliberalism remains neglected in analyses of the contemporary Western security constellation. Arguing that neoliberalism can be understood simultaneously through the Marxian concept of ideology and the Foucauldian concept of governmentality – that is, as a complementary set of 'ways of seeing' and 'ways of being' – the thesis goes on to analyse British security in policy and practice, considering it as an instantiation of a wider neoliberal way of war. In so doing, the thesis draws upon, but also challenges and develops, established critical discourse analytic methods, incorporating within its purview not only the textual data that is usually considered by discourse analysts, but also material practices of security. This analysis finds that contemporary British security policy is predicated on a neoliberal social ontology, morphology and morality – an ideology or 'way of seeing' – focused on the notion of a globalised 'network-market', and is aimed at rendering circulations through this network-market amenable to neoliberal techniques of government. It is further argued that security practices shaped by this ideology imperfectly and unevenly achieve the realisation of neoliberal 'ways of being' – especially modes of governing self and other or the 'conduct of conduct' – and the re-articulation of subjectivities in line with neoliberal principles of individualism, risk, responsibility and flexibility. The policy and practice of contemporary British 'security' is thus recontextualised as a component of a broader 'neoliberal way of war'.

Greek politics: economic crisis or crisis of democracy?

Greece’s economic instability has become the Western world’s longest-running monetary crisis. Will Germany allow the EU to keep propping up Greece’s unstable financial system? Will the country leave the eurozone? Will such a departure, if it occurs, unravel the idea of “Europe”? All valid questions. But behind them stands another equally profound social and political crisis that has made Greece the weak man of Europe.

Whose peace? Local ownership and UN peacebuilding

In recent years, there has been an increasing emphasis on the participation of national actors in United Nations peace operations, reflecting what has become a near orthodox commitment to ‘local ownership.’ Advocates of local ownership assert that it: (1) increases the legitimacy of UN peacebuilding efforts; (2) increases the sustainability of peacebuilding activities after the departure of the UN; and (3) increases democratic governance in post-conflict states. While such thinking about local ownership has informed UN peacebuilding policy to a large extent, the UN has, to date, assumed these positive benefits without critically examining the causal mechanisms that allegedly produce them, specifying the conditions under which this correlation holds, or providing convincing evidence for these assertions. Moreover, exactly what local ownership is, what is being owned, and who local ‘owners’ are remain unclear. Indeed a closer examination of ownership’s relation with legitimacy, sustainability, and democratization reveal a plethora of contradictions that imply that local ownership may in fact decrease the UN’s ability to deliver peacekeeping results. Crucially, however, the UN persists in adopting a local ownership approach to peacebuilding, suggesting that it does so because it is normatively appropriate rather than operationally effective.

The fractured lives of German Bohemian children, born 1933-40 in the area known as Sudetenland: a memory study, Nablonz-Neugablonz

At the Paris Peace Conferences of 1918-1919, new states aspiring to be nation-states were created for 60 million people, but at the same time 25 million people found themselves as ethnic minorities. This change of the old order in Europe had a considerable impact on one such group, more than 3 million Bohemian German-speakers, later referred to as Sudeten Germans. After the demise of the Habsburg Empire In 1918, they became part of the new state of Czechoslovakia. In 1938, the Munich Agreement – prelude to the Second World War – integrated them into Hitler’s Reich; in 1945-1946 they were expelled from the reconstituted state of Czechoslovakia. At the centre of this War Child case study are German children from the Northern Bohemian town and district, formerly known as Gablonz an der Neisse, famous for exquisite glass art, now Jablonec nad Nisou in the Czech Republic. After their expulsion they found new homes in the post-war Federal Republic of Germany. In addition, testimonies have been drawn upon of some Czech eyewitnesses from the same area, who provided their perspective from the other side, as it were. It turned out to be an insightful case study of the fate of these communities, previously studied mainly within the context of the national struggle between Germans and Czechs. The inter-disciplinary research methodology adopted here combines history and sociological research to demonstrate the effect of larger political and social developments on human lives, not shying away from addressing sensitive political and historical issues, as far as these are relevant within the context of the study. The expellees started new lives in what became Neugablonz in post-war Bavaria where they successfully re-established the industries they had had to leave behind in 1945-1946. Part 1 of the study sheds light on the complex Czech-German relationship of this important Central European region, addressing issues of democracy, ethnicity, race, nationalism, geopolitics, economics, human geography and ethnography. It also charts the developments leading to the expulsion of the Sudeten Germans from Czechoslovakia after 1945. What is important in this War Child study is how the expellees remember their history while living as children in Sudetenland and later. The testimony data gained indicate that certain stereotypes often repeated within the context of Sudeten issues such as the confrontational nature of inter-ethnic relations are not reflected in the testimonies of the respondents from Gablonz. In Part 2 the War Child Study explores the memories of the former Sudeten war children using sociological research methods. It focuses on how they remember life in their Bohemian homeland and coped with the life-long effects of displacement after their expulsion. The study maps how they turned adversity into success by showing a remarkable degree of resilience and ingenuity in the face of testing circumstances due to the abrupt break in their lives. The thesis examines the reasons for the relatively positive outcome to respondents’ lives and what transferable lessons can be deduced from the results of this study.

Generic relationships and dating of lineages in Winteraceae based on nuclear (ITS) and plastid (rpS16 and psbA-trnH) sequence data

Phylogenetic analyses of representative species from the five genera of Winteraceae (Drimys, Pseudowintera, Takhtajania, Tasmannia, and Zygogynum s.l.) were performed using ITS nuclear sequences and a combined data-set of ITS + psbA-trnH + rpS16 sequences (sampling of 30 and 15 species, respectively). Indel informativity using simple gap coding or gaps as a fifth character was examined in both data-sets. Parsimony and Bayesian analyses support the monophyly of Drimys, Tasmannia, and Zygogynum s.l., but do not support the monophyly of Belliolum, Zygogynum s.s., and Bubbia. Within Drimys, the combined data-set recovers two subclades. Divergence time estimates suggest that the splitting between Drimys and its sister clade (Pseudowintera + Zygogynum s.l.) occurred around the end of the Cretaceous; in contrast, the divergence between the two subclades within Drimys is more recent (15.5-18.5 MY) and coincides in time with the Andean uplift. Estimates suggest that the earliest divergences within Winteraceae could have predated the first events of Gondwana fragmentation. (C) 2009 Elsevier Inc. All rights reserved.

Processes of feelings in a society with a violent past : A qualitative study of the communication for Societal healing in the Truth Commissions in East Timor, Sri Lanka and Ghana between 2002-2011

The research investigates in what extent and how communication for meeting feelings is provided in Truth Commission work. It examines if and in what way feelings are addressed in the communication officially published by the Truth Commissions in East Timor, Ghana and Sri Lanka, occurring between 2002-2011. The research is also looking at the healing processes in a time perspective to find out if there is a communication for Societal healing to be continued in a longer term. My conclusion is that two cases of three in my research, the TRCs in Ghana and East Timor, have communication clearly directed to meet feelings caused by the war. One of the three cases (East Timor) has a communication with a clear ambition to heal over a longer period, to continue after the existence of the Truth Commission. The research suggests that communication with a clear ambition to reach out widely in the society, a communication directed to meet and process feelings over a longer period, can make Societal healing more effective. It also concludes that, in the future, Societal healing, as a field in conflict resolution, will be more based on representational media than today, provided through web communication.

The Long Game: Hamas, The IRA, and the Politics of Radicalization in Palestine and Northern Ireland

The value of a comparative study of the two conflicts stems from a remarkable similarity in the structural organization of political violence by its most influential practitioners: the IRA and Hamas. At the core, I have merely tried my best to approach a beguiling question in a fresh, dynamic way. The stultifying discourse of conflict that serves as lingua franca for the Israeli‐Palestinian issue has largely reduced strategic debate to how best the conflict can be managed – not ended. Prime Minister Benjamin Netanyahu’s focus on “economic peace” and unwillingness to commit to a two‐state solution – the consensus that has governed peacemaking for decades – belies such thinking. The Clinton Administration’s cadre of Mideast negotiators operated amidst the most rapid institutionalization of Palestinian democracy in history ‐ yet remained obsessed with Israeli‐Arab “confidence‐building” measures, doing little to legitimize the gains of Oslo. So long as Palestinians continue to view the creation of Israel as “al‐Nakba” – the catastrophe – whilst successive Israeli governments refuse to grant their aspirations any legitimacy, there can be no progress. Peace requires empathy, a substantial compromise in the context of internecine conflict. The “long war” both conflicts have become mandates an equally expansive, broad‐based and labor‐intensive approach – a demanding process that can only be called The Long Game.

Growth of transcendental meditation: a sociological study

Sociology, in concerning itself with methodology and cultural determinism,may have overlooked the value of human experience in determining social action. We feel that the structural-functionalist point of view is not mutually exclusive with that of symbolic interaction theory. The field of collective behavior has not adequately explained a certain incidence of human activity called Transcendental Meditation. This paper will define Transcendental Meditation in sociological terms and explore its growth in terms of structural-functionalism,as well as in terms of the symbol-making faculty of human experience. In the first chapter, the author will state his biases and background as well as the problem and purpose of the paper. In the second chapter, Transcendental Meditation will be defined through an explanation of its concepts in sociological terms. A view of the TM program will also be reported. Following this in the third chapter, the origins of TM will be discussed~showing its basis to be in a tradition of Indian gurus and following its development in the United states until the present. The history of TM will proceed through biography of leading figures, with special mention of innovations in the TM institution of teaching and events in the growth of the 'movement' of TOO that are of key importance. Having set down the history of TM, in the fourth chapter we will discuss TM in terms of various sociological models. We will try to identify TM as either a social movement; a charismatic organization or a bureaucracy. In the fifth chapter we will look more closely at the structure of the organization that teaches TM in regard to its own functioning; that is, compliance, communication, socialization and recruitment, and also in regard to its relationship with national institutions, such as military, industry, religion, and government. Finally, we will explore TM in terms of individual and group goals and offer an explanation defining the growth of TM. Throughout-the paper, sociological perspectives will be applied to phenomena that exist in the society today. It is not within the scope of this paper to verify all the sociological implications and appraisals offered. It is hoped that this will not invalidate the ensuing discussion. It is also hoped that this paper will expand the horizons of sociology and offer some direction in future studies of collective behavior. If this is accomplished, the author will be gratified and indebted to his teachers. If not the author takes full responsibility. This paper is dedicated therefore to Mr. Birge, Mr Morrione, Mr. Geib as well as to my parents who have encouraged me, my friends whom I have interviewed, and to His Holiness, Maharishi Mahesh Yogi whose teaching has uplifted hundred of thousands of people in the world and may bring about the development of new thresholds of peace and prosperity for mankind.

A model of capital accumulation and rent-seeking

A simple model incorporating rent-seeking into the standard neoclassical model of capital accumulation is presented. It embodies the idea that the performance of an economy depends on the efficiency of its institutions. It is shown that welfare is positively affected by the institutional efficiency, although output is not necessarily so. It is also shown that an economy with a monopolistic rent-seeker performs better than one with a competitive rent-seeking industry.

Effect of acute administration of Clenbuterol on athletic performance in horses

The aim of the study was to determine the effect of clenbuterol on the anaerobic-threshold of horses on a tread-mill with increasing physical stress, measuring heart rate (HR) and blood levels of lactate, glucose, and insulin. Twelve Arabian horses. were submitted to two physical tests separated by a 10-day interval. Clenbuterol (CL) at 0.8 mu g/kg or saline (control-C) was administered intravenously 30 minutes, before the test. The treadmill exercise test consisted of an initial warmup followed by a gradually increasing effort. There was no statistical difference in either V-2 or V-4 (velocity at which plasma lactate concentration reached 4 and 2 mmol/L, respectively) between the two-experimental groups. For the CL group, V-200, V-180, V-160, and V-140 (velocity at which the rate heart is 140, 160, 180, and 200 beats/minute, respectively) decreased significantly. At rest as well as times 4, 6, and 10 minutes, insulin levels were higher in the group that recieved clenbuterol (P < .05). Contrary to what was expected, apparently, there was no improvement in aerobic metabolism in animals when given a therapeutic dose of the bronchodilator. The elevated heart rate observed could have been attributable to the stimulation of cardiac beta(1) adrenoceptors and the increased insulin levels to the stimulation of pancreatic beta(2) receptors.

Study of the timber constructive systems that are more commercialized in Brazil

The Brazilian houses in wood are executed with several techniques and species, in function of the areas they are located, therefore, it is treated of regional traditional houses, built practically without modem technological resources. These houses are the ones of the tropical areas, where there is abundance of this material, or the ones of the south region, prevailing the European immigrant's constructive techniques. Nowadays, in the urbanized centers of the country it is observed that this type of house can be found sheltering the most lacking populations, in the slums; or in highly sophisticated residential units which are conceived and executed by specialist professionals for a social class of high purchasing power; or still, those that are marketed by companies of small load, that offer standardized residences, usually acquired by the middle class as second residence, in the field or in the coast. The work has for objective to study the houses of these companies that are consolidated at the market, identifying the constructive system, the product; as well as, its production process, trying to verify which technologies are incorporated to these processes. The analysis that was made allows a larger understanding of the product, wood house, that exists in the market and identification of the technological degree in the productive process of those constructive systems.

Thermolysis of octa (hydridodimethylsiloxyl) octasilsesquioxane in pyridine media and subsequent toluidine blue O adsorption

This work describes the synthesis of octa (hydridodimethylsiloxyl) octasilsesquioxane, (Q(8)M(8)(H)) and its thermolysis in pyridine media. The new compound called CPy was characterized by FTIR, NMR-MAS, XRD, MEV spectroscopies and TGA analyses. These results indicate that silsesquioxanes cages (octanion) are maintained after thermal treatment. A cleavage of vertex siloxy groups yielding a nanocomposite with polymeric nature is proposed. Its structure and morphology allows the adsorption/inclusion of electrochemical mediator, toluidine blue O. The square wave voltammetry analysis of resulting composite (CPyTBO) exhibits two redox couple with a formal potential (E-0') 0.1 V and 0.26 V to I and II redox couples respectively, (Britton-Robinson (BR) buffer pH 3, v = 10 Hz versus SCE) ascribed to a monomer and dimmer of the toluidine blue species. This paper opens the use of spherosiloxane derived materials a's host for small molecules in the electrochemical field. (C) 2004 Elsevier B.V. All rights reserved.
