Abstract We mainly study the block-coherence measures based on resource theory of block-coherence and the coherence measures based on positive-operator-valued measures (POVM). Several block-coherence measures including a block-coherence measure based on maximum relative entropy, the one-shot block coherence cost under the maximally block-incoherent operations, and a coherence measure based on coherent rank have been introduced and the relationships between these block-coherence measures have been obtained. We also give the definition of the maximally block-coherent state and describe the deterministic coherence dilution process by constructing block-incoherent operations. Based on the POVM coherence resource theory, we propose a POVM-based coherence measure by using the known scheme of building POVM-based coherence measures from block-coherence measures, and the one-shot block coherence cost under the maximally POVM-incoherent operations. The relationship between the POVM-based coherence measure and the one-shot block coherence cost under the maximally POVM-incoherent operations is analysed.

AbstractThis article retraces the intra-Jesuit theological debates on the theology of salvation, including the relationship between the elements of predestination, God’s foreknowledge, Grace, and free will, in the delicate passage between the sixteenth and the seventeenth centuries, and within the debates on Augustine’s theological legacy. Specifically, it explores the Flemish Jesuit Leonard Lessius’ theology and the discussions raised by it within the Society of Jesus, in order to show how soteriology has been central in the process of self-definition of the Jesuit identity in the Early Modern Age. This is particularly clear from the internal debates developed between Lessius, on the one hand, and General Claudio Acquaviva and curial theologian Roberto Bellarmino, on the other hand. Not only does the article investigate little known aspects of intra-Catholic theological debate in the post Tridentine period, but it also shows how deep pastoral and moral concerns strongly contributed to the rise of Lessius’ open-minded theology of salvation, which seemed to deprive God’s sovereign authority in favour of humankind’s free will, and human agency in the process of salvation.

The increasing number of dysfunctional families causes an increase in the number of civil litigation on the education of the child, where the relationship between the persons are highly conflictual. The actual task is study the one of components in the structure of the psychological relationship - emotional and semantic constructs underlying semantic perception of each other and the child's parents. Examination of 42 testees (parents) from harmonious families and 54 testees (parents) during the forensic psychological and psychiatric examination (regarding the definition of child`s residence or the order of meetings for the child and the parent who don`t live with it) by methods "Geometric test of relations" and "Semantic Differential" showed that in families where is highly conflictual relationship, there is positive assessments of herself and her child, while assessment of the spouse (wife) characterized inversion. This negative attitude toward the spouse (wife) is not the other parent's negative characteristics. It is the ignoring the other parent's positive characteristics. The positive acceptance of all family members was revealed in harmonious families.

Adolescence and emerging adulthood are both stages in which romantic relationships play a key role in development and can be a source of both well-being and negative outcomes. However, the limited number of studies prior to adulthood, along with the multiplicity of variables involved in the romantic context and the considerable ambiguity surrounding the construct of well-being, make it difficult to reach conclusions about the relationship between the two phenomena. This systematic review synthesizes the results produced into this topic over the last three decades. A total of 112 studies were included, following the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines. On the one hand, these works revealed the terminological heterogeneity in research on well-being and the way the absence of symptoms of illness are commonly used to measure it, while on the other hand, they also showed that romantic relationships can be an important source of well-being for both adolescents and emerging adults. The findings underline the importance of providing a better definition of well-being, as well as to attribute greater value to the significance of romantic relationships. Devoting greater empirical, educational, and community efforts to romantic development in the stages leading up to adulthood are considered necessary actions in promoting the well-being of young people.

AbstractThis work provides a definition of concentration curve alternative to the one presented on this journal by Schechtman and Schechtman (Metron 77:171–178, 2019). Our definition clarifies, at the population level, the relationship between concentration and the omnipresent ROC curve in diagnostic and classification problems.

Natural Quantum Operational Semantics with PredicatesA general definition of a quantum predicate and quantum labelled transition systems for finite quantum computation systems is presented. The notion of a quantum predicate as a positive operator-valued measure is developed. The main results of this paper are a theorem about the existence of generalised predicates for quantum programs defined as completely positive maps and a theorem about the existence of a GSOS format for quantum labelled transition systems. The first theorem is a slight generalisation of D'Hondt and Panagaden's theorem about the quantum weakest precondition in terms of discrete support positive operator-valued measures.

Este artículo trata de problematizar la definición taxonómica de Testo yonqui desde una óptica literaria que atiende a su faceta narrativa para dilucidar los cauces por los que se manifiesta en tanto que ensayo queer. Dicha problematización es abordada desde dos lugares: por un lado, desde la propia obra, atendiendo a las autodefiniciones presentes en el texto, que son examinadas a partir del marco teórico de la autobiografía; y, por otro lado, desde la recepción crítica de Testo yonqui. En último lugar, a la luz de lo anterior, se exponen una serie de tensiones relativas a la relación entre narración, referente y representación en la propuesta experimental del principio autocobaya.   This article aims to question the taxonomical definition of Testo Junkie from a literary perspective that considers its narrative aspect in order to elucidate the ways in which it can be regarded as a queer essay. Such questioning is approached from two angles: on the one hand, from the work itself, examining the self-definitions found in the text, which are studied on the basis of the theoretical framework of autobiography; and, on the other hand, from Testo Junkie’s critic reception. Lastly, the principle of the auto-guinea pig is also explored, in reference to the series of tensions arising from the relationship between narration, referent and representation.

Clausewitz’s writings stand in two traditions. On the one hand, with his own very narrow definition of strategy, “Strategy is the use of the [military] engagement for the purpose of the war,” he continued a tradition that goes back to Paul-Gédéon Joly de Maizeroy and beyond him to Byzantine Emperor Leo VI. It is not least because of Clausewitz’s espousal of this tradition that this narrow definition still dominated Soviet thinking. On the other hand, Clausewitz stood in a new tradition reflecting on the relationship between a political purpose of the war itself. This goes back to Guibert, Kant, Rühle von Lilienstern but also a long-forgotten anonymous work probably written by Zanthier. This dwelt on the bureaucratic process of strategy-making in the interface between (politically dominated) foreign policy and (hardware- and means-dominated) military policy. It is ultimately to the latter tradition that we owe his reflections on the domination of political considerations captured in his famous line about war being the continuation of politics by other means. This in turn is the foundation on which most other reflections on grand strategy have been built.

The interplay between the Colonial Office and British businessmen around the turn of the last century forms the background of this essay. Although the subject has been well-documented in a number of scholarly books and articles, we still lack an unambiguous definition of the relationship. Wide interpretations are still possible on the limits and the extent of the influence exercised by both officials and entrepreneurs. On the one hand, it is argued that the Colonial Office “had an instinctive dislike of government intervention in economic activity.”...

Abstract What is the relationship between religion and modern media? Are the media in essence anti-religion and a means to remove religion? Or are they a neutral means that can also be in the service of religion? Such questions fall under the category of the relationship between religion, modernization, and the nature of modernization, about which there can be found a rich literature in Iran. As far as the relationship between religion and modernization is concerned, two related approaches can be followed: 1) an historical-sociological approach and 2) a philosophical approach. Under the influence of either approach one would face a spectrum of opinions which, on the one hand, lead to “technological dogmatism” and, on the other, lead to “instrumentalization”. To decide which of these opinions to accept depends upon our historical situation (our destiny) and our definition of dichotomous sides (religion and media), as well as on our historical-sociological and philosophical reasoning in this matter. This article deals with these points. Since the national media attempts to act upon the implications expected by modern media within the framework of moral criteria and religious recommendation, then we will turn to this fundamental question: How can religious matters be addressed in the public media, so as to be able to involve a passive audience that is supposedly not the addressee of the message, and turn him or her into an active audience? In this regard, taken from the media experiences both in Iran and around the world, first the characteristics of “religious media” will be offered. Then a pattern for media rituals will be introduced and experimentally (as a case study) studied through some examples in Iranian society, and next the need for a more exact planning will be tapped. Finally the necessary conditions to develop such rituals in the national media will be dealt with.

This article concerns the designation of civil unions expressed in French and Polish legal language, serving a dual purpose: epistemological and analytical. On the one hand, the relationship between conceptualization and the definition of real entities in the terminological perspective will be examined, as, indeed, terminological investigations, including jurilinguistics, allows for examining the relationship between real entities, concepts as mental constructions, and terms which designate them in languages for specific purposes. On the other hand, the designations of civil unions in the French and Polish law will be compared, demonstrating that sometimes they result from the same legal tradition and, in other cases, reflect cultural changes that inform the coinage of new terminological units.
