Abstract
We show that, contrary to the common wisdom, the workload process in a _uid queue with
a cluster Poisson input can converge, in the slow growth regime, to a Fractional Brownian
motion, and not to a L?vy stable motion. This emphasizes lack of robustness of L?vy stable
motions as _bird-eye_ descriptions of the tra_c in communication networks.

Bibliographics for the 983 eprints in the live archives of E-LIS : trends and status report up to 7th July 2004, based on author-self-archiving metadata
Full text linkThe priority for ideas and philosophy related to "Network Theory" have been traced back and documented by Braun(2004),and credit goes to Karinthy(1929).The IT has empowered to realise it, as the most practical phenomena and it is no more a humour. The OAI (Open Archives Initiatives)and ACIS (Academic Contributor Information System)are progressive in the direction ,which may lead to realise the "Collective Genius" at global level. Focus of present study is on Author-Self-Archiving (A-S-A)Metadata of the 983 Eprints in the Live Archives of the E-LIS (EPrints of Library and Information Science),which were approved till 7th July 2004.The A-S-A Metadata was used for librametric analysis. Self-explanatory bibliographics are illustrated.The highlights include: Conference papers (34%); highest approval, June 2004 (28%); published archives (76%);not refereed (52%); not in public domain (60%); highest self-archiving-author (De Robbio, Antonella).The Nos. of EPrints having single JITA domain specifications were: Theoretical and general aspects of libraries and information(27); Information use and sociology of information(80);Users,literacy and reading(13);Libraries as physical collections(30);Publishing and legal issues(57);Management(13);Industry, profession and education(36);Information sources, supports, channels(113) ; Information treatment for information services, Information functions and techniques (101); Technical services libraries, archives and museums(25); Housing technologies(1); Information technology and library technology(92); and Inter-domainery (395) i.e. having specifications of two or more than two JITA classes
Verses, subverses and subversions in contemporary postcolonial poetry : the arts of resistance in the works of Linton Kwesi Johnson and Lesego Rampolokeng
No full textIncludes bibliographical references (leaves 136-141).This dissertation seeks to analyse insubordination and resistance manifested in postcolonial and post-apartheid poetry as ways of subverting dominant Western discourses. More specifically, I focus my analysis on textual strategies of resistance in the poetry of Linton Kwesi Johnson and Lesego Rampolokeng. The syncretistic quality in the oeuvres of both poets is related to diaspora, hybridity and crealisation as forms of writ[h]ing against (neo)colonially-based hegemonic discourses. Postcolonial critiques at large will frame this analysis of strategies of domination and resistance, but some discussions from the domain of history, sociology and cultural studies may also enter the debate. In this regard there is a great variety of theories and arguments dealing with the contradictions and incongruities in the question of power relations interconnecting domination and resistance. This study is arranged in three pivotal debates. There is firstly an in-depth discussion of underpinning theories that deal with strategies of domination and resistance in the postcolonial domain This is a threefold task carried out by scrutinising (a) the origins of colonial discourse and its binarist tendencies, (b) the pitfalls of anticolonialist resistance based on dualistic opposites, and (c) the hybrid and insubordinate nature of resistance as an efficient alternative to transcend such binaries. Afterwards I seek to investigate how strategies of diasporic resistance and cultural hybridism employed in the poetry of Linton Kwesi Johnson can contribute to moving away from the limitations of dichotomies and also subvert hegemonic power. And finally, I look at crealisation, mockery and insubordination as strategies of resistance in the postapartheid poetry of Lesego Rampolokeng. Besides that, this project is concerned with the increasing importance of academic studies on postcolonial literatures. The present research aims therefore to analyse postcolonial and post-apartheid poems as strategic techniques to decentre dominant Western rhetoric that tries to naturalise inequalities and injustices in the relations between power holders and the powerless in both local and global contexts

Time for consensus: establishing core outcomes meaningful to survivors of out-of-hospital cardiac arrest
No full textMore people are surviving out-of-hospital cardiac arrest (OHCA) than ever before, yet meaningful functional recovery and reintegration into daily life remain uncertain for many survivors.1, 2 Current clinical guidelines, consensus statements, and quality standards all emphasize the importance of systematically measuring quality of life, functional impairments, cognitive deficits and psychopathology. Survivors’ outcome measures are primarily used in three key areas: firstly, in clinical practice, where outcome measures enable identification and monitoring of survivors’ individual problems; secondly, in clinical registries and observational research studies, to better understand the epidemiology of cardiac arrest survivorship; and thirdly, in interventional research studies to determine and compare the effect of survivor aftercare intervention.</p

Addressing fragmentation in cardiac arrest survivorship research: the Cardiac Arrest Research Hub
No full textThe 2025 European Resuscitation Council “Systems Saving Lives” guidelines and their updated Chain of Survival explicitly recognise the importance of survivorship. They emphasise the long-term process of recovery and focus on improving the quality of life for survivors and their supporters. Yet, there are many challenges to implementing these recommendations. Surviving a cardiac arrest is still relatively rare, with diverse consequences requiring multidisciplinary input via different health and third sector services.</p
