Two postulates concerning observables on a quantum logic are formulated. By Postulate 1 compatibility of observables is defined by the strong topology on the set of observables. Postulate 2 requires that the range of the sum of observables ought to be contained in the smallestC-closed sublogic generated by their ranges. It is shown that the Hilbert space logicL(H) satisfies the two postulates. A theorem on the connection between joint distributions of types 1 and 2 on the logic satisfying Postulate 2 (...) is proved. (shrink)

The theory of nearly orthosymmetric ortholattices generalizes the theory of orthosymmetric ortholattices defined by one of the authors in a previous paper. In this theory, some equations allow one to distinguish complex Hilbertian lattices from real and quaternion ones.

An effect algebra is a partial algebraic structure, originally formulated as an algebraic base for unsharp quantum measurements. In this article we present an approach to the study of lattice effect algebras (LEAs) that emphasizes their structure as algebraic models for the semantics of (possibly) non-standard symbolic logics. This is accomplished by focusing on the interplay among conjunction, implication, and negation connectives on LEAs, where the conjunction and implication connectives are related by a residuation law. Special cases of LEAs are (...) MV-algebras and orthomodular lattices. The main result of the paper is a characterization of LEAs in terms of so-called Sasaki algebras. Also, we compare and contrast LEAs, Hájek's BL-algebras, and the basic algebras of Chajda, Halaš, and Kühr. (shrink)

Two different generalizations of Brouwer–Zadeh posets (BZ posets) are introduced. The former (called pre-BZ poset) arises from topological spaces, whose standard power set orthocomplemented complete atomic lattice can be enriched by another complementation associating with any subset the set theoretical complement of its topological closure. This complementation satisfies only some properties of the algebraic version of an intuitionistic negation, and can be considered as, a generalized form of a Brouwer negation. The latter (called degenerate BZ poset) arises from the so-called (...) special effects on a Hilbert space. It is shown that the standard Brouwer negation for effect operators produces a degenerate BZ poset with respect to the order induced from the partial sum operation. (shrink)

For any unit vector in an inner product space S, we define a mapping on the system of all ⊥-closed subspaces of S, F(S), whose restriction on the system of all splitting subspaces of S, E(S), is always a finitely additive state. We show that S is complete iff at least one such mapping is a finitely additive state on F(S). Moreover, we give a completeness criterion via the existence of a regular finitely additive state on appropriate systems of subspaces. (...) Finally, the result will be generalized to general inner product spaces. (shrink)

Effect algebras (EAs), play a significant role in quantum logic, are featured in the theory of partially ordered Abelian groups, and generalize orthoalgebras, MV-algebras, orthomodular posets, orthomodular lattices, modular ortholattices, and boolean algebras.We study centrally orthocomplete effect algebras (COEAs), i.e., EAs satisfying the condition that every family of elements that is dominated by an orthogonal family of central elements has a supremum. For COEAs, we introduce a general notion of decomposition into types; prove that a COEA factors uniquely as a (...) direct sum of types I, II, and III; and obtain a generalization for COEAs of Ramsay’s fourfold decomposition of a complete orthomodular lattice.

Richard Janko's acclaimed translation of Aristotle's _Poetics_ is accompanied by the most comprehensive commentary available in English that does not presume knowledge of the original Greek. Two other unique features are Janko's translations with notes of both the _Tractatus Coislinianus_, which is argued to be a summary of the lost second book of the Poetics, and fragments of Aristotle’s dialogue On Poets, including recently discovered texts about catharsis, which appear in English for the first time.

The article discusses two bioart projects that bring the symbolically core human substances of blood, sweat and tears into technologically mediated relationships with plants and fungi to explore human kinship with other species: Tarah Rhoda’s BS&T (short for ‘blood, sweat and tears’) and OurGlass, and Saša Spačal’s MycoMythologies: Patterning. The article analyses the art projects through the lens of the molecular gaze and different perspectives on kinning, bringing anthropological conceptualizations of kinship together with Haraway’s pathways to connect with other species. (...) How can bioart use technologies to explore interspecies kinship through a molecular gaze? And may such artworks contribute to the toning down of human exceptionality in the face of a precarious future? We find that artworks providing a molecular gaze on interspecies biological processes may risk a decontextualized approach to complex relational processes but may also create new visions of filiation even with biological organisms imagined to be genetically distant from humans, thus spurring awareness of the fragile interrelationships among species.

Introduction:To meet and take care of people with dementia implicate professional and moral challenges for caregivers. Using force happens daily. However, staff also encounter challenges with the management in the units. Managing the caretaking function is also significant in how caretakers experience working in dementia care.Purpose:The purpose of this study is to explore the caregiver’s experiences with ethical challenges in dementia care settings and the significance of professional leadership in this context.Method:The design is qualitative, and data appear through narrative interviews. (...) A total of 23 caretakers participated in the study. The transcribed interviews were subjected to a phenomenological-hermeneutical interpretation.Ethical considerations:The respondents signed an informed consent for participation prior to the interviews. They were assured anonymity and confidentiality in the publication of the data. Ricoeur’s method for interpretation ensures anonymity as the researcher relates to the data as one collective text. The study is part of a larger research project in ethics, in its entirety approved in line with the Helsinki Convention.Results:The findings show that the caretakers experienced inadequacy. Some of them described a negative work atmosphere where they experienced that their leaders did not take them seriously. Because of this, informal negative sub-groups functioned as an exclusive debriefing arena. Some of the informants described the opposite experience where the leaders actively supported them.Discussion:The analyses of the findings are discussed in light of the concepts of trust and mistrust in leadership.Conclusion:There is a correlation between the leadership and the caregivers’ experience of being in difficult situations.

Rawls offers three arguments for the priority of liberty in Theory, two of which share a common error: the belief that once we have shown the instrumental value of the basic liberties for some essential purpose (e.g., securing self-respect), we have automatically shown the reason for their lexical priority. The third argument, however, does not share this error and can be reconstructed along Kantian lines: beginning with the Kantian conception of autonomy endorsed by Rawls in section 40 of Theory, we (...) can explain our highest-order interest in rationality, justify the lexical priority of all basic liberties, and reinterpret Rawls’ threshold condition for the application of the priority of liberty. Perhaps unsurprisingly, this Kantian reconstruction will not work within the radically different framework of Political Liberalism. (shrink)

The Principles of Biomedical Ethics by Beauchamp and Childress is a classic in the field of medical ethics. The first edition was published in 1979 and “unleashed” the four principles of respect for autonomy, non-maleficence, beneficence, and justice on the newly emerging field. These principles were argued to be mid-level principles mediating between high-level moral theory and low-level common morality, and they immediately became very popular in writings about medical ethics. Over the years Beauchamp and Childress have developed this approach (...) and vigorously defended it against the various criticisms that have been raised. The 5th edition of this book is, as all the …. (shrink)

Theologians are split into two groups: those who embrace prosperity theology and those who oppose it; both sides on scriptural grounds. Those criticising it embrace cessationism in its diversity, while its supporters are mainly found among Pentecostals and Charismatics, who are continuationists. Continuationists believe and teach that all gifts of the Spirit are still available to the church today, therefore should be practised by the church just as they were operative during the apostolic era. Therefore, it is clear that prosperity (...) preachers are continuationists. They believe and practice healing and miracle gifts today. A review of the literature, biblical texts, historical teachings, and Pentecostal and Neo-Pentecostal (also referred to as charismatic and neo-charismatic) form the basis of this article. It addresses the positive features of prosperity teachers’ beliefs and methods as well as how they exploit the dreams, fears, and aspirations of people living in poverty. The theology of sharing, as articulated by Nicholas B.H. Bhengu, is proposed as a solution to creating parity between the rich and the poor.Contribution: This article seeks to balance opposing theological approaches with the prosperity gospel. It does this by introducing a theology of sharing as taught by Nicholas Bhengu based on the philosophy of Ubuntu, a way of life among African people. The challenge for theologians on both sides of the argument is finding a way to accommodate the other side’s contributions. (shrink)

Analyzes the origin, structure and resolution of Kant's antinomies of reason from a systematic rather than a historical perspective, exploring the relationship between the theoretical antinomies and the practical antinomy in order to indicate their similarities and differences and to suggest the dependence of the latter on the former.

In the quantum logic approach, Bell inequalities in the sense of Pitowski are related with quasi hidden variables in the sense of Deliyannis. Some properties of hidden variables on effect algebras are discussed.

Without seeking to diminish its authority as the Word of God, this article acknowledges the Fourth Gospel as a brilliant piece of literary artistry by the implied author. The aim of this article is to substantiate this assertion by conducting a study on focalisation and illustrating how it invites the implied reader’s participation in the narrative. This contribution acknowledges the existence of insightful contributions on the topic, particularly in relation to the Fourth Gospel. However, it asserts that the study of (...) the performative nature of focalisation in this particular Gospel has not received the attention it deserves. The main contribution of this article is its analysis of a selected narrative of the Fourth Gospel using focalisation as an analytical tool, with the objective of demonstrating that the Fourth Gospel is performative in nature, crafted and formulated to consistently engage the implied reader in considering its purpose, as stated in 20:30–31.Contribution: The article showcases that focalisation, when used as an analytical tool, can unlock, and enable the interpreter of the Fourth Gospel to recognise its performative nature to the implied reader of the text. This is critical, given that the text is crafted to encourage the reader to participate in it by making decisions regarding their faith in Jesus Christ. (shrink)
