The phenomenon of irreversibility is explained on the basis of an analysis by H. L. Frisch. The history of the debate over irreversibility is briefly discussed, including Boltzmann’s H-theorem, Zermelo's Wiederkehreinwand, Poincaré recurrences, Loschmidt's Umkehreinwand and Liouville’s theorem. The derivation of irreversible behavior for the ideal gas position distribution is carried out explicitly. Using this derivation, the Wiederkehreinwand and the Umkehreinwand are revisited and explained. The first thing we must establish is the meaning of the term ‘irreversibility’. This is not quite as trivial as it might seem. The irreversible behavior I will try to explain is that which is observed. Every day we see that time runs in only one direction in the real world,.

The interdisciplinary field of person-environment relations has, from its origins, addressed the transactional relationship between human behavior and the built environment. This body of knowledge has been based upon qualitative and quantitative assessment of phenomena in the “real world.” This knowledge base has been instrumental in advancing the quality of real, physical environments globally at various scales of inquiry and with myriad user/client constituencies. By contrast, scant attention has been devoted to using simulation as a means to examine and represent person-environment transactions and how what is learned can be applied. The present discussion posits that press-competency theory, with related aspects drawn from functionalist-evolutionary theory, can together function to help us learn of how the medium of film can yield further insights to person-environment (P-E) transactions in the real world. Sampling, combined with extemporary behavior setting analysis, provide the basis for this analysis of healthcare settings as expressed throughout the history of cinema. This method can be of significant aid in examining P-E transactions across diverse historical periods, building types and places, healthcare and otherwise, otherwise logistically, geographically, or temporally unattainable in real time and space.

This paper describes a new approach to documenting media art which seeks to place in dialogue the artist's intentions and the audience's experience. It explicitly highlights the productive tension between the ideal, conceptual existence of the work, and its actual manifestation through different iterations and exhibitions in the real world. The paper describes how the approach was developed collaboratively during the production of a documentary collection for the artwork Giver of Names, by David Rokeby. It outlines the key features of the approach including artist's interview, audience interviews and data structure.

Nikifor Krynicki (Epifaniusz Drowniak, 1895-1968) was one of the most popular non-academic Polish painters worldwide. To show the biblical inspiration in his creative output I chose two categories from various thematic aspects: self-portraits and landscapes with a church. There are plenty of Nikifor’s paintings showing him as a teacher, as a celebrating priest, as a bishop, or even as Christ. A pop­ular way to explain this idea of self-portraits is a psychological one: as a form of auto-therapy. This analysis is aims to show a deeper expla­nation for the biblical anthropology. Nikifor’s self-portraits as a priest celebrating the liturgy are a symbol of creative activity understood as a divine re-creation of the world. Such activity needs divine inspira­tion. Here are two paintings to recall: Potrójny autoportret (The triple self-portrait) and Autoportret w trzech postaciach (Self-portrait in three persons). The proper way to understand the self-identification with Christ needs a reference to biblical anthropology. To achieve our re­al-self we need to identify with Christ, whose death and resurrection bring about our whole humanity. The key impression we may have by showing Nikifor’s landscapes with a church is harmony. The painter used plenty of warm colors. Many of the critics are of the opinion that Nikifor created an imaginary, ideal world in his landscapes, the world he wanted to be there and not the real world. The thesis of this article is that Nikifor created not only the ideal world, but he also showed the source of the harmony – the divine order.

Abbot Kōnyo’s pastoral letter of 1871 codifies an understanding of the Pure Land as a transcendent realm, attainable only after death, and of faith as a private matter of the heart. This understanding is valuable as a way of negotiating a place for Shinshū in the regime of the modern nation-state. Early Meiji thinkers like Shimaji Mokurai rely on this understanding of religion as internal in arguing for the separation of church and state. Shinshū reformer Kiyozawa Manshi pushes this focus on interiority to its limit, destabilizing the complementary relationship between the Buddhist law and the imperial law that his predecessors sought to secure. During the Taishō, Kiyozawa’s disciple Kaneko Daiei attempts to rearticulate the connection between the ideal Pure Land and the real world, while the Honganji-ha thinker Nonomura Naotarō argues that it is time for the Pure Land tradition to set aside the myth of the Western Paradise.

Like other components of Semantic Web-based applications, ontologies are evolving over time to reflect changes in the real world. Several of these applications require keeping a full-fledged history of ontology changes so that both ontology instance versions and their corresponding ontology schema versions are maintained. Updates to an ontology instance could be non-conservative that is leading to a new ontology instance version no longer conforming to the current ontology schema version. If, for some reasons, a non-conservative update has to be executed, in spite of its consequence, it requires the production of a new ontology schema version to which the new ontology instance version is conformant so that the new ontology version produced by the update is globally consistent. In this paper, we first propose an approach that supports ontology schema changes which are triggered by non-conservative updates to ontology instances and, thus, gives rise to an ontology schema versioning driven by instance updates. Note that in an engineering perspective, such an approach can be used as an incremental ontology construction method driven by the modification of instance data, whose exact structure may not be completely known at the initial design time. After that, we apply our proposal to the already established [Formula: see text]OWL (Temporal OWL 2) framework, which allows defining and evolving temporal OWL 2 ontologies in an environment that supports temporal versioning of both ontology instances and ontology schemas, by extending it to also support the management of non-conservative updates to ontology instance versions. Last, we show the feasibility of our approach by dealing with its implementation within a new release of the [Formula: see text] OWL-Manager tool.

Abstract Background and Aims Extended-release calcifediol (ERC), active vitamin D analogs (VDA), and nutritional vitamin D (NVD) are the predominant vitamin D therapies (VDTs) commonly used for treatment (Tx) of secondary hyperparathyroidism (SHPT) in adults with stage 3 or 4 non-dialysis chronic kidney disease (ND-CKD) and vitamin D insufficiency (VDI). Clinical trials have demonstrated varying efficacy on serum total 25-hydroxyvitamin D (25D) and intact parathyroid hormone (iPTH) across VDTs. This study aimed to descriptively assess the real-world experience of various VDTs in increasing 25D, reducing iPTH, and modifying serum calcium (Ca). Method Medical records of the first 376 adult patients with stage 3 or 4 CKD and a history of SHPT and VDI who met study criteria from 18 geographically representative United States nephrology clinics were reviewed from 1 year before through 1 year after initiation of VDT. Key study variables included patient demographics, medication usage, and laboratory results. The study population had a mean age of 69.5 years with gender and racial distributions representative of the US ND-CKD population. Patients were stratified into cohorts based on their index therapy at index date: ERC (n=174), VDA (n=55) and NVD (n=147). Results Patients treated with NVD were predominantly CKD Stage 3 (69.4%), while CKD Stage 4 were the majority of those treated with ERC (53.4%) and VDA (61.8%). The ERC Tx’ed subjects demonstrated an increase in 25D by 23.7 ± 1.6 ng/mL (p<0.001) and a decrease iPTH by 35 ± 6.2 pg/mL (p<0.001) without statistically significant impact on serum calcium (Ca) and phosphorus (P) levels. The VDA Tx’ed group demonstrated an increase in 25D by 5.5 ± 1.3 ng/mL (p<0.001) without statistically significant impact on iPTH and serum phosphorus levels. Additionally, serum Ca increased by 0.2 ± 0.1 pg/mL (p<0.001) among VDA recipients. The NVD Tx’ed group demonstrated an increase in 25D by 9.7 ± 1.6 ng/mL (p<0.001) without statistically significant impact on iPTH and serum Ca and P levels (Table 1). Conclusion Clinical effectiveness and safety varied across VDTs. ERC was the only VDT which significantly reduced mean iPTH in the real world setting despite highest mean levels at baseline among the three cohorts. Additionally, subjects treated with ERC demonstrated the largest mean increase in 25D and ERC was the only VDT which raised mean 25D to the normal range (>30 ng/mL). Patients treated with ERC and NVD saw no statistically significant impact on serum Ca and P levels; however, those treated with VDAs saw a small, but statistically significant increase in serum Ca levels.

Can we burn the signs and journey without maps? In other words, can we travel from representational theories, through Baudrillard's critique of representation, to forms of theory that are somehow nonrepresentational? In this paper I hijack and go beyond Baudrillard's concepts of the precession and orders of simulacra to illustrate two main things: first, how the history of geographical thought has been one of representational theory, where there was seen to be a relationship, and then commutation, of theory and the real world; second, how representational theories are perhaps out of tune, unable to explain adequately, or change, our digital and commodity—sign soaked culture of simulacra, simulations, and reproductions. Overall, I attempt to show clearly how, through his poststructuralist critique of representation, Baudrillard is challenging us to rethink theory as doubly nonrepresentational.

This study is intended to answer three main questions. First, how does the Z generation in Malang City responds to the use of hermeneutics as a method of interpreting the Qur'an by Muslim scholars? Second, how is the process of transmitting their knowledge about it? And third, how is the construction of their knowledge about the ideal interpretation of the Qur'an and can respond to socio-religious dynamics and phenomena? This study is a field study, while the primary respondents are Z generation in Malang City. The use of descriptive, hermeneutic, and intertext analysis models on data, the results of this study showed that there are differences conveyed by the Z generation of Malang City related to the use of hermeneutics as a method of interpretation of the Qur'an: some of them accept it, while others reject it. The transmission of their knowledge about hermeneutics also varies; most of them are correlated with social media, some are still conventional, which relies on information from teachers, and so on. This showed that generation Z of Malang city is not entirely averse to issues that tend to be controversial. Moreover, the authority for interpreting the Qur'an has not entirely shifted from the real world to cyberspace, no matter how dependent they are on the new media.

This contribution discusses the limits to the ideal of human rights in the context of a triple dynamic: the reason of State and its limits; the ecological reason and its call to protect the planet and the ecosystem; and the techno-scientific reason as a supreme reason which ultimately could lead to the refusal of any limit. It suggests that if we consider human rights as a dynamic and transformative process and not as a static concept, these rights remain the counterpoint to the derailments of globalization. They seem more than ever necessary for the emergence of a truly common law. If the interplays of limits are well defined, human rights would make this truly common law more flexible by giving it a variable content within limits which allows it to adapt better to the diversity of the real world.


A new realist movement in continental philosophy has emerged to challenge philosophical approaches and traditions ranging from transcendental and speculative idealism to phenomenology and deconstruction for failing to do justice to the real world as it is ‘in itself’, that is, as independent of the structures of human consciousness, experience, and language. This volume presents a collection of essays that take up the challenge of realism from a variety of historical and contemporary philosophical perspectives. This volume includes essays that engage the fundamental presuppositions and conclusions of this new realism by turning to the writings of seminal figures in the history of philosophy, including Kant, Schelling, and others. Also included are essays that challenge anti-realist readings of Merleau-Ponty, Derrida, and Nancy. Finally, several essays in this volume propose alternative ways of understanding realism through careful readings of key figures in German idealism, pessimism, phenomenology, existentialism, feminism, and deconstruction.
