Rosa Luxemburg
No full textLa traduzione di questo breve scritto di Hannah Arendt – che uscì originariamente come recensione alla biografia di Peter J. Nettl (Rosa Luxemburg, Oxford University Press, 1966) in «The New York Revi-ew of Books» del 6 ottobre 1966 con il titolo A Heroine of Revolution – aggiunge un tassello interessante per la ricostruzione del giudizio sul marxismo e sulla vicenda del comunismo nel Novecento. La parte più originale della lunga postfazione di Rosalia Peluso (Lo spirito ri-voluzionario. Hannah Arendt nello specchio di Rosa Luxemburg, pp. 57-132) è quella dove viene misurato, in maniera precisa e circostan-ziata, il debito di Hannah Arendt nei confronti dell’opera di Rosa Lu-xemburg. Senza dubbio questo debito è significativo. Si potrebbe ri-cordare quel breve testo postumo del 1950-1951, intitolato Le uova alzano la voce, dove Arendt (ben prima degli eventi del 1956) parla degli ex-comunisti, delle loro insuperate ambiguità, e assume le os-servazioni di Rosa Luxemburg sulla rivoluzione russa (quelle del 1905 ancora più di quelle postume del 1922) come una profezia: par-la infatti delle «contestazioni» e degli «ammonimenti precoci ... con-tro la mancanza di una democrazia interna al partito» e conclude che «è ancora il fantasma di Rosa Luxemburg ad assillare le coscienze de-gli ex comunisti della generazione più vecchia»
La Vestale 'incesta'
No full textMarcello Salvadore: La Vestale incesta.
Dionysius of Halicarnassus, Pliny the Younger and Plutarch are the sources
of a detailed account of Vestalis incesta’s punishment: they say that she was
sentenced to death. Dionysius adds that there was no after death ritual.
Modern scholars generally accept what the three authors assert. In this article
the author surmises that the Vestalis incesta, together with the parricida, was
not condemned to death: both of them were sentenced to a particular kind
of banishment from the Society
From collaboration models to BPEL processes through service models
No full textThis paper proposes a model-based lifecycle for the development of web services, which is based on two kinds of models, collaboration models and service ones. After agreeing upon a collaboration model, which is a public specification, each party can work out a service model and then can turn it into a process written in an orchestration language such as BPEL. As the conceptual gap between a service model and its BPEL implementation is relevant, this paper is concerned with the automatic mapping of service models to BPEL processes, in line with model-based development. Moreover it discusses how to validate services with respect to collaboration models both at-design time and at run-time, and presents the bProgress software environment, which is made up of a number tools developed during this research
Managing variability in process-aware information systems
No full textConfigurable process models are integrated representations of multiple variants of a process model in a given domain, e.g. multiple variants of a shipment-to-delivery process in the logistics domain. Configurable process models provide a basis for managing variability and for enabling reuse of process models in Process-Aware Information Systems. Rather than designing process models from scratch, analysts can derive process models by configuring existing ones, thereby reusing proven practices. This thesis starts with the observation that existing approaches for capturing and managing configurable process models suffer from three shortcomings that affect their usability in practice. Firstly, configuration in existing approaches is performed manually and as such it is error-prone. In particular, analysts are left with the burden of ensuring the correctness of the individualized models. Secondly, existing approaches suffer from a lack of decision support for the selection of configuration alternatives. Consequently, stakeholders involved in the configuration of process models need to possess expertise both in the application domain and in the modeling language employed. This assumption represents an adoption obstacle in domains where users are unfamiliar with modeling notations. Finally, existing approaches for configurable process modeling are limited in scope to control-flow aspects, ignoring other equally important aspects of process models such as object flow and resource management. Following a design science research method, this thesis addresses the above shortcomings by proposing an integrated framework to manage the configuration of process models. The framework is grounded on three original and interrelated contributions: (i) a conceptual foundation for correctness-preserving configuration of process models; (ii) a questionnaire-driven approach for process model configuration, providing decision support and abstraction from modeling notations; (iii) a meta-model for configurable process models covering control-flow, data objects and resources. While the framework is language-independent, an embodiment of the framework in the context of a process modeling language used in practice is also developed in this thesis. The framework was formally defined and validated using four scenarios taken from different domains. Moreover, a comprehensive toolset was implemented to support the validation of the framework

Configurable Process Models: How To Adopt Standard Practices In Your How Way?
No full textConfigurable process models enable a systematic documentation and reuse of standardized "best" practices, while allowing process analysts to understand possible variations contemplated by these standards, and to link these variations to business decisions. This article discusses the potential benefits of configurable process models and introduces a method and a toolset for process design based on configurable process models

Automated discovery of process models from event logs: Review and benchmark
No full textProcess mining allows analysts to exploit logs of historical executions of business processes to extract insights regarding the actual performance of these processes. One of the most widely studied process mining operations is automated process discovery. An automated process discovery method takes as input an event log, and produces as output a business process model that captures the control-flow relations between tasks that are observed in or implied by the event log. Various automated process discovery methods have been proposed in the past two decades, striking different tradeoffs between scalability, accuracy and complexity of the resulting models. However, these methods have been evaluated in an ad-hoc manner, employing different datasets, experimental setups, evaluation measures and baselines, often leading to incomparable conclusions and sometimes unreproducible results due to the use of closed datasets. This article provides a systematic review and comparative evaluation of automated process discovery methods, using an open-source benchmark covering twelve publicly-available real-life event logs and eight quality metrics. The results highlight gaps and unexplored tradeoffs in the field, including the lack of scalability of several methods and a strong divergence in their performance with respect to the different quality metrics used

Semiconductor Quantum Dots as Components of Photoactive Supramolecular Architectures
No full textLuminescent quantum dots (QDs) are colloidal semiconductor nanocrystals consisting of an inorganic core covered by a molecular layer of organic surfactants. Although QDs have been known for more than thirty years, they are still attracting the interest of researchers because of their unique size-tunable optical and electrical properties arising from quantum confinement. Moreover, the controlled decoration of the QD surface with suitable molecular species enables the rational design of inorganic-organic multicomponent architectures that can show a vast array of functionalities. This minireview highlights the recent progress in the use of surface-modified QDs - in particular, those based on cadmium chalcogenides - as supramolecular platforms for light-related applications such as optical sensing, triplet photosensitization, photocatalysis and phototherapy
