The concept of strong admissibility plays an important role in dialectical proof procedures for grounded semantics allowing, as it does, concise proofs that an argument belongs to the grounded extension without having necessarily to construct this extension in full. One consequence of this property is that strong admissibility (in contrast to grounded semantics) ceases to be a unique status semantics. In fact it is straightforward to construct examples for which the number of distinct strongly admissible sets is exponential in the number of arguments. We are interested in characterizing properties of collections of strongly admissible sets in the sense that any system describing the strongly admissible sets of an argument framework must satisfy particular criteria. In terms of previous studies, our concern is the signature and with conditions ensuring realizability. The principal result is to demonstrate that a system of sets describes the strongly admissible sets of some framework if and only if that system has the property of being decomposable.

This chapter discusses the significance of Abdullah Quilliam by primarily focusing on the writings through which he framed his conversion to Islam and wrote as a lens for Victorian society to revisit Islam. A classification of the types of writing undertaken and their role in the promotion of Islam within Britain and internationally in the late Victorian and Edwardian period is explored. Quilliam wrote extensively on the crisis facing Victorian Christianity and was intensely aware of the burning political issues of his time, especially those concerning British foreign policy. However, above all else, he was a Muslim of conviction, and the leader of British Muslims, and his unique status lies in his promotion of Islam in the West as a religious worldview disconnected from ethnicity or "otherness." This examination of his writings explores his vision of Islam and demonstrates that Quilliam’s concerns in his writings remain the essential themes drawn upon by young contemporary British Muslim activists and converts to the religion.

Infinite Utility Streams

The paper studies the sensitivity implications of the class of monotone social preference orders on infinite utility streams which satisfy the axioms of Equity (Finite Anonymity) and Stationarity (Independent Future). The principal result of this investigation is that representability of such preference orders implies a certain lack of sensitivity to the utility stream of any finite number of generations, which we refer to as ‘insensitivity to the present’. Our result points to a fundamental difficulty in implementing the sustainability principle, which requires intertemporal social preferences to reflect fairly the interests of the generations in the present and in the future.

Abstract From its inception, the Jewish community in Livorno enjoyed a unique status, encouraging former conversos to settle there. In Livorno they could live openly as Jews. Thus, it is most interesting to study their attitude to their cultural heritage, according to the wills left by several of the Sephardi community’s prominent members. A linguistic analysis of phrases used by three testators is particularly revealing in assessing their positions regarding Judaism. Their words reflect anxiety and determination: a realization of hardships encountered by New Christians on their way to Judaism, and a further realization that only few will adhere to it.

Abstract Paul Valéry’s interest in the life sciences is an important yet little-studied aspect of his work. Although Valéry was known primarily as a reader of mathematics and physics, his fascination with the life sciences has often been ignored or regarded as mere curiosity. This article examines Valéry’s writing on the subject of biology by focusing on the unique status he accords to the notion of life. In both his theoretical and poetic writings, Valéry addresses the notion of life as a category endowed with distinct ontological attributes — as a phenomenon that encompasses a distinct type of order. Life, as an independent force, is capable of resisting and even reversing the principle of entropy, which Valéry regards as a universal tendency towards degradation and dispersion that affects all inanimate matter. Valéry’s thought thus exhibits a complicated yet clear affinity with the intellectual tradition known as vitalism. The article discusses this affinity by analysing the presence of vitalist ideas and imagery in Valéry’s corpus, giving special attention to his most expressly ‘biological’ work, the essay ‘L’Homme et la coquille’ (‘The Man and the Seashell’).

AbstractThe energy transition is causing many stability-related challenges for power systems. Transient stability refers to the ability of a power grid’s bus angles to retain synchronism after the occurrence of a major fault. In this paper a set-based approach is presented to assess the transient stability of power systems. The approach is based on the theory of barriers, to obtain an exact description of the boundaries of admissible sets and maximal robust positively invariant sets, respectively. We decompose a power system into generator and load components, replace couplings with bounded disturbances and obtain the sets for each component separately. From this we deduce transient stability properties for the entire system. We demonstrate the results of our approach through an example of one machine connected to one load and a multi-machine system.

The article identifies two approaches to determining the linguistic conditions of the emergence and functioning of the myth. The first approach assumes that the myth is a manifestation of unconscious (M. Müller) or conscious (E. Cassirer, R. Barthes) distortion of language. Within this approach it is impossible to escape from myth because the presentation of the facts of the world in language is inescapable, which is always imperfect. These distortions are meant for political influence, as according to the proponents of the conscious mythologizing of language. Philosophy is tasked with resisting such distortions and, consequently, myth creation in general. This approach seems simplified, because the myth is identified here with the linguistic form of its distribution, reduced to the analysis of distortions of language presentation. At the same time, the psychological and epistemological preconditions of the myth, its unique status in the life of communities are lost. Conditions for the development of the second approach arise through the critique of classical rationality by several influential thinkers who undermined the belief in the exclusive ability of discursive language to present the truth (F. Nietzsche, L. Wittgenstein, M. Heidegger). The second approach assumes that the myth emerges and continues to exist due to the inability of the logos to present some important aspects of reality, especially its existential dimension (P. Tillich, H. Blumenberg, L. Hatab, K. Morgan). In this case, myth and logos become alternative and at the same time closely connected linguistic ways of presenting the truth. Logos (the language of science) presents primarily abstract causal connections of essences. At the same time, mythical narratives are better than science at presenting the mysteries of origin and existence, creating a hierarchy of values for communities.

Women’s Narratives of Displacement and their AfterlifeThis paper focuses on the connection between life writ­ing and postmemory. The case of Anița Nandriș-Cudla’s life writing is presented based on its unique status: women’s testimonies are rare in Romanian memory discourse, and when present, they are lim­ited to known intellectual figures. Moreover, the displacement narratives occupy a small place in Ro­mania’s post-1989 collective memory discourse and, as survivors of deportation inexorably pass away, life writing becomes increasingly important in the transmission of memory. This paper argues that increasing attention to the narratives of the past traumas can develop the intergenerational transmission of memory and knowledge. The process of coming to terms with the past must offer space to alternative memories and narratives with which, the research shows, second or third generations can relate, based on similarities and resemblance, and in this way develop an empathic understanding of current events.Женские свидетельства о переселениях лиц и их жизнь после смерти В данной статье основное внима­ние уделяется связи между биографическими писаниями и записями о прошедших событиях postmemory. Писания о жизни Аниты Нандрис Кудла представлены здесь благодаря иx уни­кальному статусу, так как женские свидетельские показания очень редки в румынских произ­ведениях и записях, связанных с историческими событиями и, даже если они присутсвуют, они ограничиваются показаниями известных интеллектуальных личностей. Кроме того, записи о переселениях занимают небольшое место в писаниях коллективной памяти Румынии после 1989-го года и, вместе со смертью тех, кто остался в живых после депортаций, писание о их жизни становится все более важным в процессе передачи памяти. В данной работе утверждается, что повышенное внимание к прошлым травмам способствует передаче воспоминаний и знаний следующим поколениям. Восприятие прошлого должно также оставить место для альтернативных воспоминаний и записей, в которых, как показывают исследования, вторые и третьи поколения могут найти много общего и таким образом развивать в себе способность эмпатически понимать текущие события.
