Today, Service-Oriented Architecture (SOA) and Grid and Cloud computing comprise the key technologies in distributed systems. In systems following the SOA approach, functionalities are delivered and consumed as services. Given the variety of resources (i.e. data, computing capabilities, applications, etc) as well as the variation of user-requested Quality of Service (e.g., high performance, fast access, low cost, high media resolution, etc), there is a need for advanced user management, trust establishment and service management mechanisms which adjust, monitor and evaluate service (...) provision according to the users’ requirements and rights. Within this context, security and privacy requirements have become of great importance, as well the need for flexible and efficient identity management. This editorial of the special issue Identity Management in Grid and SOA discusses the importance of identity management within SOA and Grid environments. A number of techniques and existing systems addressing these issues are presented and evaluated. Identity management is considered in various contexts and at different levels, including service composition level, system level and inter-system communication level. (shrink)
Over the past few years, the Virtual Organization (VO) paradigm has been emerging as an ideal solution to support collaboration among globally distributed entities (individuals and/or organizations). However, due to rapid technological and societal changes, there has also been an astonishing growth in technologies and services for mobile users. This has opened up new collaborative scenarios where the same participant can access the VO from different locations and mobility becomes a key issue for users and services. The nomadicity and mobility (...) introduces additional challenges for managing collaboration in VO environments. This paper focuses on the Identity Management challenge in a Mobile Dynamic VO environment, which is a VO that takes into account nomadicity and seamless mobility aspects as elaborated within the EU funded project Akogrimo (Access to Knowledge through the Grid in a mobile world). The resulting work is the design of the Akogrimo Identity Management system supporting the authentication and authorization process across the different administrative domains of the Mobile Dynamic VO. This design follows the service oriented approach and integrates the different perspectives: that of the network, that of the user and that of the service provider. Such an integration requires facing challenges; both from the architectural and technological viewpoints because different ‘worlds’ (i.e. network and service level) leverage different (and sometimes conflicting) approaches when addressing Identity Management.

Although Kant (1998) envisaged a prominent role for logic in the argumentative structure of his Critique of Pure Reason, logicians and philosophers have generally judged Kantgeneralformaltranscendental logics is a logic in the strict formal sense, albeit with a semantics and a definition of validity that are vastly more complex than that of first-order logic. The main technical application of the formalism developed here is a formal proof that Kants logic is after all a distinguished subsystem of first-order logic, namely what (...) is known as geometric logic.

It is neither desirable nor possible to eliminate normative concerns from the psychology of reasoning. Norms define the most fundamental psychological questions: What are people trying to do, and how? Even if no one system of reasoning can be the norm, pure descriptivism is as undesirable and unobtainable in the psychology of reasoning as elsewhere in science.
At the center of every well‐constructed theory of education is a philosophical anthropology‐reasoned speculation as to the origins on man's conditions in the history of culture, especially the particular phenomenon of consciousness that underlies historical periods. Using the lens of one of the most significant theories of culture produced, we examine the philosophical anthropological accounts reflected in the theories of John Dewey and Kieran Egan, which are responsible for their divergent educational plans.
The aim of this article is to define and delineate an ethical mindset. In deploying an interpretive mixed-methods analysis of the Australian services sector, data were collected through an online survey on 223 respondents followed by focus group interviews involving 20 participants. The analysis reveals evidence of ethical mindsets in Australian business context, the components of which are identified as being aesthetic judgment, spirituality, optimism, harmony and balance, contentment, truth telling, individual responsibility and professionalism. While the findings are limited to (...) the Australian context, it illuminates the value of mindsets to business ethics in a way that has theoretical rigour and practical relevance. Research has so far only considered business ethics within other mindsets (e.g. global mindset). This article provides a foundation for further application and development of mindset theory. (shrink)
The aim of this article is to examine the usefulness of spirituality and aesthetics for generating new perspectives and understandings with regard to business ethics. Using an interpretive mixed-methods approach, data were collected through an online survey of 223 respondents and focus group interviews with 20 participants. Analysis of the quantitative and qualitative data suggests that the presence of aesthetic spirituality and religious spirituality, along with the factors of optimism, contentment, making a difference and interconnectedness, are significantly associated with ethical (...) practice in the workplace. These factors may be focused upon when considering the ethical climate of organizations. Although this research does not support universal conclusions, the relationship between ethics, spirituality and aesthetics identified in the Australian services sector might be replicated elsewhere.

Hellenistic ruler cult has generated much scholarly interest and an enormous bibliography; yet, existing studies have tended to focus on the communal character of the phenomenon, whereas the role of private individuals in ruler worship has attracted little attention. This article seeks to redress this neglect. The starting point of the present study is an inscription Διὶ | καὶ βασιλεῖ | Φιλίππωι Σωτῆρι on a rectangular marble plaque from Maroneia in Thrace. Since the text was published in 1991, it has (...) been disputed whether the king in question is Philip II or Philip V of Macedon. The question is further complicated by a newly published text from Thasos, plausibly restored to read [Β]ασιλέως Φιλί[ππου] | σωτῆρος. The identity of the king in these texts is a matter of great historical significance: if Philip II is meant, not only would this impinge on the question of his divinity, he would also be the first king called Sōtēr, thus providing the earliest attestation of a cult epithet spreading from the traditional gods to monarchs. The first part of this article will re-examine the king's identity by studying these two texts in connection with other dedications similarly addressed to a ‘King Philip’ and apparently set up by private individuals. The second will move beyond Macedonia: it will draw on potential parallels from the Attalid, Seleucid and Ptolemaic kingdoms and explore the possible contexts in which individuals set up similar objects. It will be demonstrated that, while there is evidence from other Hellenistic kingdoms of seemingly ‘private’ dedications set up according to civic or royal commands, in Macedonia the piecemeal and isolated nature of the evidence does not permit a conclusive answer. But whether set up spontaneously or by civic command, these objects provide important evidence for the interaction between the public and the private aspects of ruler worship. (shrink)
While the vocabulary of sacrifice has been the subject of detailed studies, the terms of votive offerings in ancient Greece still lack a semantic survey of their own. I am here interested in a particular type of offering, the so-called ‘first-fruit’ offerings, in Archaic and Classical Greece. It was a common practice in different parts of the Greek world for individuals and cities to bring an offering termed ἀπαρχή to the gods using a portion of the proceeds from a variety (...) of human activities; and this act is described by the verb ἀπάρχεσθαι. And yet the word ἀπάρχεσθαι is not limited to making dedications; it is also used in sacrificial procedures and cult payments. This study aims to give a semantic analysis of these terms, examining their religious applications in different contexts. It appears that the values attached to the notion of ἀπάρχεσθαι are rather different in the cases of sacrifices, of bringing first-offerings and of cult finance. The ways in which the usages of these terms overlap with and diverge from each other constitute one of the most interesting results. Alors que le vocabulaire du sacrifice a fait l’objet d’études détaillées, les termes désignant les offrandes votives en Grèce ancienne souffrent toujours de l’absence d’enquête sémantique spécifique. Il s’agit ici d’étudier un type particulier d’offrandes, à savoir les offrandes de prémices, en Grèce archaïque et classique. Il était habituel en différents lieux du monde grec, tant pour les individus que les cités, d’apporter aux dieux une offrande appelée ἀπαρχή, en prélevant une partie des bénéfices issus de diverses activités humaines. Cette action était désignée par le verbe ἀπάρχεσθαι. Le terme ne se limite pas à l’action dédicatoire. Il est aussi utilisé dans des procédures sacrificielles et des paiements cultuels. Cette étude entend fournir une analyse sémantique de ces termes, en examinant leurs applications religieuses dans différents contextes. Il apparaît que les valeurs attachées à la notion d’ἀπάρχεσθαι doivent être distinguées selon qu’il s’agit du cadre des sacrifices, de l’offrande de prémices et du financement des cultes. Il est particulièrement intéressant de distinguer ainsi les manières dont ces termes se recouvrent ou se différencient les uns des autres dans l’usage qui en est fait. (shrink)
Theognostos is a well-known author of a surviving orthographical work and a lost history of the revolt of Euphemios in Sicily. Although the dating of the Orthography was the subject of controversy in the distant past, the issue has long been considered as settled: the work is generally thought to have been dedicated to Emperor Leo V , not Leo VI , as the opposite opinion held. The present article reexamines the problem on the basis of a re-evaluation of all (...) available evidence as well as by bringing new parallels into the discussion. The solution reached goes some way in-between the two previous propositions. According to it, the Orthography would still derive from Theognostos' teaching experience in the first half of the ninth century , but would date from mid-century. The dedication of the author's magnum opus would have taken place much later, in the very early reign of Leo VI, for reasons also discussed here. Thus, Theognostos emerges as a ninth-century figure and a contemporary of Patriarch Photios. (shrink)
The aim of this article is to investigate the relatively neglected and under-theorized area of ethical mindsets in the Australian services sector. Employing a mixed-methods approach, quantitative data was collected through online survey of 66 items and qualitative data was collected by focus group interviews with 20 participants. An analysis of the survey data suggests that ethical mindsets exist, and the qualitative analysis allowed the identified components to be refined. This research potentially adds to developing business ethics literature about ethical (...) mindsets and contributes to the methodological debate about the efficacy of online surveys and the mixed-methods approach.

Using a conviction-based measure, we find that local public corruption exerts a negative effect on the lending activity of US banks. Our baseline estimations show that the difference in public corruption between, for example, Alabama, where corruption is high, and Minnesota, where corruption is low, implies that banks headquartered in the former state grant 0.55% less credit ceteris paribus. Using proxies for relationship lending and monitoring, we also find that these bank characteristics weaken the negative effect of public corruption on (...) lending. These results are robust to tests that address endogeneity, to the use of perception-based measures of corruption, and after controlling for credit demand conditions. In further analysis, we show that these effects are more evident for smaller banks and banks operating in a single state. These findings provide evidence that public corruption could facilitate information asymmetry in the lending market and, thus, could hinder local development by reducing bank credit. (shrink)
This article reads Malu De Martino’s 2010 film Como Esqueçer as a case study in self-harm as a mode of expression and self-inquiry. Drawing on disability and queer theory, psychoanalysis, and sociology of medicine, the author argues that How to Forget charts a “crip” epistemology of self-harm and theorizes a “social self.” That is to say, the film models an orientation towards self-harm that offers a coalitional and social therapeutic understanding. Based on this reading, the author suggests the application of (...) practices of knowing-with, or knowing-in-relation as “cripistemology” to a broader therapeutic, research, and lay context. (shrink)
En el presente texto, el proyecto arquitectónico se considera respecto a las líneas trazadas y las palabras escritas de su proceder. Estas huellas escritas del proyecto, que aparecen en su dualidad, condensan un pensamiento que pertenece exclusivamente a la arquitectura y a su proyectar. El estudio de los signos de esta _doble escritura_proyectual arquitectónica nos permite un acceso a este particular pensar. En vez de la dialéctica entre lo icónico y lo verbal, la presente aproximación al proyecto arquitectónico considera los (...) signos de la _doble escritura_ sistemáticamente como una unidad de significancia cuya interpretación se halla en algo fuera del _logos;_ se halla en el lugar de la obra arquitectónica. El concepto del signo de Charles S. Peirce, en tanto que _relación tridimensional_ entre tres factores, nos permite asignar a los signos de la doble escritura una interpretación. (shrink)
Preserving traditions, particularly in rural areas, can be regarded as a safety mechanism for those who can trace their roots to the respective regions. This entails the certainty of belonging to a specific social group. Therefore, in order to remain unchanged, customs and traditions need to be cultivated in the hearts of the younger generations as true spiritual values.
The Hellenistic period was an era of literary canons, of privileged texts and collections. This volume examines the genesis of the Lyric Canon, and explores the process of canonization of lyric poetry and the textual transmission and preservation of lyric poems from the archaic period through to the Hellenistic era.
Nationalism appears to be so entrenched in political life and discourse, that its illiberal face is often deemed to be an exception and unfortunate coincidence triggered by international terrorism. Alternatively, it may be depicted as the result of ill-thought policies which can be reversible. In this paper, I argue that liberal nationalism is conceptually flawed and politically illiberal. Illiberal tendencies are an integral part of it and these cannot be corrected by ‘taming’ unruly nationalism or by articulating ‘benign’ adaptations of (...) it. Because the liberal and illiberal faces are interwoven in complex ways, my suggestion is to look far ahead and beyond it. The territory may be uncharted, but a commitment to a pro-human welfare orientation could open the way for separating liberalism from nationalism and aligning the former with critical democratic politics. The challenge, as I see it, is to articulate a liberal anationalism which by affirming equal human dignity and the importance of non-domination could sustain inclusionary and democratic communities.

This paper addresses the history of late nineteenth century women’s suffrage and the history of the women involved in the struggle for female enfranchisement of Australia, New Zealand, and Colorado, which have recently been the target of fervent postcolonial criticism. The paper will attempt to defend the efforts of white suffragists by deconstructing the groundlessness and, occasion- ally, the falseness of postcolonial criticism.
In this paper I tackle the relationship between language, knowledge and power. To this end, I try to give some reasons for the non-arbitrariness of some words, as well as for the non-arbitrariness of grammatical genders in Romance languages, especially Romanian and French. I focus on several specific linguistic structures and uses of particular words in these two languages. I particularly deal with the construction of a third grammatical gender, the neuter, in Romanian, in comparison to the two grammatical genders (...) existing in French, trying to see how the application of Irigarayís theory on the gender of nouns functions for Romanian language. There is no third grammatical gender in French, and therefore Irigarayís argument is proved to be invalid for Romanian. The questions that lead my analysis are: What corporeality does the third grammatical gender, the neuter in Romanian, point to? How are we to consider neuter words? Is the neuter a necessary and sufficient proof for considering Romanian a less sexist lan- guage? Is the neuter the guarantor of impartiality and equilibrium in a grammatically gendered language?

The article provides textual evidence for the partial, subtle dependence of Theodore Daphnopates' sermon On the Birth of John the Baptist on Homily 42 on the same subject by Emperor Leo VI . This finding is then brought into correlation with Theodore's homiletic oeuvre and its production environment. Through its exploitation of the given source the sermon in question emerges as being directly related to Emperor Constantine VII and his literary preferences, as is the case with other works of Theodore's (...) as well.
