BackgroundCritical Incident Reporting Systems (CIRS) provide a well-proven method to identify clinical risks in hospitals. All professions can report critical incidents anonymously, low-threshold, and without sanctions. Reported cases are processed to preventive measures that improve patient and staff safety. Clinical ethics consultations offer support for ethical conflicts but are dependent on the interaction with staff and management to be effective. The aim of this study was to investigate the rationale of integrating an ethical focus into CIRS.MethodsA six-step approach combined the (...) analysis of CIRS databases, potential cases, literature on clinical and organizational ethics, cases from ethics consultations, and experts’ experience to construct a framework for CIRS cases with ethical relevance and map the categories with principles of biomedical ethics.ResultsFour main categories of critical incidents with ethical relevance were derived: (1) patient-related communication; (2) consent, autonomy, and patient interest; (3) conflicting economic and medical interests; (4) staff communication and corporate culture. Each category was refined with different subcategories and mapped with case examples and exemplary related ethical principles to demonstrate ethical relevance.ConclusionThe developed framework for CIRS cases with its ethical dimensions demonstrates the relevance of integrating ethics into the concept of risk-, quality-, and organizational management. It may also support clinical ethics consultations’ presence and effectiveness. The proposed enhancement could contribute to hospitals’ ethical infrastructure and may increase ethical behavior, patient safety, and employee satisfaction. (shrink)

Background Recent publications reveal shortcomings in evidence review and summarization methods for patient decision aids. In the large-scale "Share to Care (S2C)" Shared Decision Making (SDM) project at the University Hospital Kiel, Germany, one of 4 SDM interventions was to develop up to 80 decision aids for patients. Best available evidence on the treatments' impact on patient-relevant outcomes was systematically appraised to feed this information into the decision aids. Aims of this paper were to (1) describe how PtDAs are developed (...) and how S2C evidence reviews for each PtDA are conducted, (2) appraise the quality of the best available evidence identified and (3) identify challenges associated with identified evidence. Methods The quality of the identified evidence was assessed based on GRADE quality criteria and categorized into high-, moderate-, low-, very low-quality evidence. Evidence appraisal was conducted across all outcomes assessed in an evidence review and for specific groups of outcomes, namely mortality, morbidity, quality of life, and treatment harms. Challenges in evidence interpretation and summarization resulting from the characteristics of decision aids and the type and quality of evidence are identified and discussed. Conclusions Evidence reviews in this project were carefully conducted and summarized. However, the evidence identified for our decision aids was indeed a "scattered landscape" and often poor quality. Facing a high prevalence of low-quality, non-directly comparative evidence for treatment alternatives doesn't mean it is not necessary to choose an evidence-based approach to inform patients. While there is an urgent need for high quality comparative trials, best available evidence nevertheless has to be appraised and transparently communicated to patients. (shrink)

Solidarity is supposed to facilitate collective action. We argue that it can also help overcome false consciousness. Groups practice if they pool information about what is in their true interest and how to vote accordingly. The more numerous can in this way overcome the but only if they are minimally confident with whom they share the same interests and only if they are better-than-random in voting for the alternative that promotes their interests. Being more cohesive and more competent than the (...) Masses, the Elites can employ the same strategy perhaps all the more effectively. But so long as the Masses practice epistemic solidarity they will almost always win, whether or not the Elites do. By enriching the traditional framework of the Condorcet Jury Theorem with group-specific standards of correctness, we investigate how groups can organize to support the alternatives truly in their interests.

Physical inactivity and coronavirus disease 2019 signify two pandemics with negative physical, mental, and economic consequences. Younger and older people have not reached the recommended physical activity level for years. Societal restrictions due to COVID-19 additionally reduce opportunities for physical activity, and they increase social isolation. Here, we outline how playing exergames with others at home could foster physical and mental health and promote communication and discussions on exergaming. Accordingly, we highlight the educational and social benefits of exergaming at home (...) and delineate the concept of Educational and Social Exergaming. We outline specific benefits and pitfalls of exergaming regarding its physical and nonphysical effects, including educational values of discussing exergaming experiences and related topics. Moreover, we discuss the relevance of practical guidelines for educational and social exergaming at home as well as prospects for future research. Overall, educational and social exergaming could alleviate several detrimental effects of both pandemics on the health and well-being of people of all ages. (shrink)

In theTractatus, Wittgenstein advocates two major notational innovations in logic. First, identity is to be expressed by identity of the sign only, not by a sign for identity. Secondly, only one logical operator, called “N” by Wittgenstein, should be employed in the construction of compound formulas. We show that, despite claims to the contrary in the literature, both of these proposals can be realized, severally and jointly, in expressively complete systems of first-order logic. Building on early work of Hintikka’s, we (...) identify three ways in which the first notational convention can be implemented, show that two of these are compatible with the text of theTractatus, and argue on systematic and historical grounds, adducing posthumous work of Ramsey’s, for one of these as Wittgenstein’s envisaged method. With respect to the second Tractarian proposal, we discuss how Wittgenstein distinguished between general and non-general propositions and argue that, claims to the contrary notwithstanding, an expressively adequate N-operator notation is implicit in theTractatuswhen taken in its intellectual environment. We finally introduce a variety of sound and complete tableau calculi for first-order logics formulated in a Wittgensteinian notation. The first of these is based on the contemporary notion of logical truth as truth in all structures. The others take into account the Tractarian notion of logical truth as truth in all structures over one fixed universe of objects. Here the appropriate tableau rules depend on whether this universe is infinite or finite in size, and in the latter case on its exact finite cardinality.As it is obviously easy to express how propositions can be constructed by means of this operation and how propositions are not to be constructed by means of it, this must be capable of exact expression.5.503.

Spatial perspective taking is an everyday cognitive process that is involved in predicting the outcome of goal directed behavior. We used dynamic virtual stimuli and fMRI to investigate at the neural level whether motion perception interacts with spatial perspective taking in a life-like design. Subjects were asked to perform right-left-decisions about the position of either a motionless, hovering or a flying ball , either from their own or from the perspective of a virtual character . Our results showed a significant (...) interaction of STIMULUS TYPE and PERSPECTIVE with significantly increased activation in right posterior intraparietal sulcus for 1PPDYN condition. As the IPS is critically involved in the computation of object-directed action preparation, we suppose that the simple perception of potentially action-relevant dynamic objects induces a ‘readiness for action’, restricted to the 1PP. Results are discussed against the background of current theories on embodiment and enactive perception. (shrink)

ZusammenfassungPatientenmobilität und grenzüberschreitende Gesundheitsversorgung sind alltägliche Phänomene in der Europäischen Union. Im Jahr 2011 hat die EU eine Richtlinie erlassen, um in diesem Kontext Rechtssicherheit herzustellen. Bisher gibt es keine umfassenden systematischen Studien über ethische Aspekte grenzübergreifender Gesundheitsversorgung. In dieser Arbeit werden die rechtlichen Entwicklungen der grenzübergreifenden Gesundheitsversorgung dargestellt und die in der Literatur vereinzelt erwähnten ethisch relevanten Aspekte heuristisch und auf Patiententypologien aufbauend systematisch inventarisiert und diskutiert. Es zeigt sich, dass die Möglichkeit der Patientenmobilität und die damit vor allem (...) verbundenen Finanzierungsregelungen die Autonomie einiger Patienten sicherlich verbessern kann. Allerdings können wohl nicht alle Patienten Versorgungsverbesserungen erwarten. Im Gegenteil können sogar negative Konsequenzen für einige Patienten folgen, was vor allem aus gerechtigkeitstheoretischen Überlegungen kritisch zu sehen ist. (shrink)

Posing the question ‘How diverse is philosophy of education in the West?’ this paper responds to two recent defences of African philosophy of education which endorse its communitarianism and oppose individualism in Western philosophy of education. After outlining Thaddeus Metz's argument that Western philosophy of education should become more African by being more communitarian, and Yusef Waghid's defence of communitarianism in African philosophy of education, we develop a qualified defence of aspects of individualism in education. Our reservations about some aspects (...) of communitarianism lead us to argue for a role for some forms of individualism in African as well as Western education. Finally, reflecting on what is at stake in this kind of comparative philosophy of education, we argue that an over-emphasis on cultural differences can distract philosophers of education from the attention they should pay to the common dangers posed across continents by the influence of global capitalism on education.

ObjectivesAcupuncture therapy has been used for cognitive impairment-related diseases, however, there are still few studies on the overall trend of acupuncture therapy on cognitive impairment based on bibliometric analysis. The purpose of this study was to explore the research trend of the impact of acupuncture on cognitive impairment in the past 15 years, analyze the research trends and hotspots, and provide new ideas and theoretical basis for future research directions.MethodsFrom the Web of Science Core Collection, the relevant literature on the (...) treatment of cognitive impairment with acupuncture from 2007 to 2022 was retrieved. Then, based on the CiteSpace and VOSviewer software of the Java platform, the cooperation between countries and institutions in this field, the co-citation of journals and documents, and the cooperation between authors and authors, etc. were analyzed. In addition, the co-occurrence and burst analysis of keywords are also carried out, and a visual knowledge map is drawn.ResultsAs of August 08, 2022, a total of 394 records related to the treatment of cognitive impairment with acupuncture were identified. The analysis results show: The number and rate of annual publications have steadily increased, with some fluctuations from year to year. The countries that contribute the most to this field are China and the USA. Among them, Beijing University of Chinese Medicine and Capital Medical University are tied for first place in terms of the number of published papers. Tao Jing is the most prolific author and the number one cited author.ConclusionsThe number of publications on acupuncture for cognitive impairment is expected to increase rapidly in future research, suggesting a bright future for the field. Future research hotspots will focus on pain, injury, protocol, diagnosis, guidelines, etc. It is also necessary to strengthen cross-regional and cross-country cooperation among various academic groups.

In the early stages of the COVID-19 pandemic, Italy, Spain, New York, and Hong Kong stood out for the ir high rates of infections. Given this scenario, a web-based international multisite and cross-sectional study was conducted between April and May 2020 to investigate the psychological impact of the pandemic and the restrictions imposed by the governments in these countries. We expected similar patterns in European countries, and no significant differences in terms of psychological impairment between Hong Kong and the other (...) areas. Participants were 1955 adults from the above-mentioned areas. We assessed anxiety, depression, COVID-19-related threats, and perceived burden of restrictive measures. Two-explorative factor analyses with Promax rotation identified COVID-19-related factors: personal physical threat, personal economic threat, global economic threat, and restriction-related burden. ANOVAs studied locations’ differences and two-separate hierarchical multiple regression analyses by location determined whether and how COVID-19-related variables were associated with anxiety and depression, adjusting for age and sex. Italy and Hong Kong showed higher anxiety than Spain ; Hong Kong scored higher on depression than Italy and Spain, which highlighted the lowest mean-score. New York participants showed the poorest mental health conditions. Anxiety was predicted by restriction-related burden and personal economic threat in New York and Hong Kong ; by global economic threat and restriction-related burden in Italy ; and by personal physical threat in Spain. Depression was predicted by restriction-related burden and personal economic threat in New York and Hong Kong ; by global economic threat in Italy ; and no predictors emerged in Spain. Findings could contribute to understanding the specific impact of the pandemic on people’s psychological health in each area, along with the factors that impacted mental health. This information may be useful to implementing prevention interventions in case of restrictions. (shrink)

When people interact with social robots, they treat them as real social agents. How people depict robots is fun to consider, but when people are confronted with embodied entities that move and talk – whether humans or robots – they interact with them as authentic social agents with minds, and not as mere representations.

In the paper we construct a new kind of fractional dynamical model, i.e. the fractional relativistic Yamaleev oscillator model, and explore its dynamical behaviors. We will find that the fractional relativistic Yamaleev oscillator model possesses Lie algebraic structure and satisfies generalized Poisson conservation law. We will also give the Poisson conserved quantities of the model. Further, the relation between conserved quantities and integral invariants of the model is studied and it is proved that, by using the Poisson conserved quantities, we (...) can construct integral invariants of the model. Finally, the stability of the manifold of equilibrium states of the fractional relativistic Yamaleev oscillator model is studied. The paper provides a general method, i.e. fractional generalized Hamiltonian method, for constructing a family of fractional dynamical models of an actual dynamical system. (shrink)

The exploration of plant behavior on a cellular scale in a minimal invasive manner is key to understanding plant adaptations to their environment. Plant hormones regulate multiple aspects of growth and development and mediate environmental responses to ensure a successful life cycle. To monitor the dynamics of plant hormone actions in intact tissue, we need qualitative and quantitative tools with high temporal and spatial resolution. Here, we describe a set of biological instruments (reporters) for the analysis of the distribution and (...) signaling of various plant hormones. Furthermore, we provide examples of their utility for gaining novel insights into plant hormone action with a deeper focus on the drought hormone abscisic acid. (shrink)

To do theology in the twenty-first century, we must understand Hegel. In this accessible introduction, Tseng examines the philosopher's significant influence on European thought in general and Protestant theology in particular.

I thought the paper by Kai-yee Wong and Chris Fraser was fascinating and insightful. Two things I especially appreciated are the clarity with which they summarize my views. I think they are quite fair and accurate. Second, I appreciate their suggestion that the way to deal with the practical problem of weakness of will has much to do with the role of the Background in shaping our actions. I think they are especially on the right track when they say that (...) the improvement of Background skills may actually narrow the range of real options for action, (p. 21) nonetheless, they do not decrease freedom. As they say, “It is a process of strengthening the self, and the agent is likely to experience the concomitant restriction of ‘live’ options not as a limitation but as strength of character.” (p. 21). That seems to me very much on the right track. What they are suggesting, and it is a powerful addition to my own writings, is that we should not just think of the Background as facilitating languages, games and social practices generally, but for morality as well (p. 23).

Kai Nielsen is one of Canada's most distinguished political philosophers. In a career spanning over 40 years, he has published more than 400 papers in political philosophy, ethics, meta-philosophy, and philosophy of religion. Pessimism of the Intellect presents a thoughtful collection of Nielsen's essays complemented by an extended reflective interview with Nielsen. This collection allows the reader to grasp the systematic scope of his thought and methodology.

In einer qualitativen Interviewstudie zur Situation und zu Veränderungen in deutschen Krankenhäusern berichteten GeschäftsführerInnen und ÄrztInnen übereinstimmend von hohem und zunehmendem Druck, mittels der medizinisch-pflegerischen Leistungen Gewinne machen zu müssen. Während die GeschäftsführerInnen dabei jedoch bei patientenbezogenen ärztlichen Entscheidungen keine ethischen Konflikte sahen, berichteten ÄrztInnen von erheblichen Verletzungen des ärztlichen Ethos. Während die GeschäftsführerInnen erklärten, sie würden von den ÄrztInnen „ethisch korrektes Entscheiden“ erwarten, berichteten ÄrztInnen, dass die Rahmenbedingungen ihrer Arbeit die Unabhängigkeit ärztlicher Entscheidungen untergrüben, indem betriebswirtschaftliche Interessen die Medizin (...) korrumpierten. Entscheidungen zur stationären Aufnahme, zur Wahl der Behandlungsprozesse und zur Entlassung der PatientInnen seien in zunehmendem Maße an wirtschaftlichen Interessen des Hauses und damit nicht allein an den medizinischen Bedarfen der PatientInnen orientiert. GeschäftsführerInnen bewerteten die Unabhängigkeit ärztlicher Entscheidungen hoch, während ÄrztInnen diese als deutlich eingeschränkt bezeichneten. Die Ergebnisse verweisen auf ungelöste Konflikte zwischen Medizinethik und „Ökonomie“. Organisationsethik ist zur Vermittlung auf der Ebene der Krankenhäuser und des Gesundheitswesens insgesamt gefordert. Sie muss sich darüber hinaus mit der Wissensproduktion im Feld der Versorgungs- und Qualitätsforschung kritisch auseinandersetzen. (shrink)

The starting point of this chapter is the uncontroversial assumption that the right to defend the innocent against unjust aggression is limited to the infliction of necessary harm and is further limited to the infliction of proportionate harm. The aim of the chapter is to shed light on the nature and location of those limits. The chapter is divided into three sections. In the first section it is argued that both unnecessary and disproportionate defense infringe upon the rights of an (...) unjust aggressor. The final two sections address, respectively, the questions of where the boundary between necessary and unnecessary defense is located and of where the boundary between proportionate and disproportionate defense is located. Those questions turn out to be more complicated than is often noticed, and the answers reached in these sections are novel ones. (shrink)

We investigate whether ordinary quantification over objects is an extensional phenomenon, or rather creates non-extensional contexts; each claim having been propounded by prominent philosophers. It turns out that the question only makes sense relative to a background theory of syntax and semantics (here called a grammar) that goes well beyond the inductive definition of formulas and the recursive definition of satisfaction. Two schemas for building quantificational grammars are developed, one that invariably constructs extensional grammars (in which quantification, in particular, thus (...) behaves extensionally) and another that only generates non-extensional grammars (and in which quantification is responsible for the failure of extensionality). We then ask whether there are reasons to favor one of these grammar schemas over the other, and examine an argument according to which the proper formalization of deictic utterances requires adoption of non-extensional grammars.

Even outside Europe, human beings have long contemplated philosophical questions. This book explores Neo-Confucianism and its most important representative: Zhu Xi (1130-1200). In Medieval China, Indian Buddhism was widely received; many endorsed the idea that the self and the world are illusionary (i.e. "empty") but that "emptiness" (sunyata) can be known in meditation. Although Neo-Confucian thinkers in the 11th and 12th centuries also practiced meditation, Buddhist ideas otherwise represented a nuisance for them. In his careful reconstruction, Kai Marchal examines which (...) concepts, ways of speaking, and practices these Neo-Confucians developed to achieve a realistic worldview grounded in ordinary life. "Emptiness" was transformed into the unity of all things. Moreover, Marchal comes to the surprising conclusion that Zhu Xi's thought continues Buddhism in one crucial respect: in the conception of a reflective self-relation located in the world, which is not intended to strengthen the human tendency to egocentricity, but rather to weaken it.

Metaphilosophy is itself philosophy about philosophy. It is not something before or independent of philosophy. Both Kai Nielsen and Richard Rorty are deeply concerned (someone might say obsessively preoccupied) with metaphilosophy. They both are thoroughly historicist and contextualist resolutely rejecting any form of a transcendental or metaphysical turn. They argue against claims to absolute validity (as well as against absolutism in any form) and a natural order of reasons: some 'Reason' to which any rational agent must be committed. They both (...) see philosophy as a transitional genre first (historically speaking) from religion then metaphysics and more latterly from scientistic conceptions of the world. But they differ about what philosophy is transitional to. For Rorty it is historical narrative and utopian proposals; for Nielsen it is critical theory. Rorty claims this, Nielsen's intentions to the contrary notwithstanding, commits him to enlightenment rationalism. Nielsen replies that his form of critical theory is deeply historicist and contextual without being resolutely atheoretical. This plays out in political orientation to Nielsen's being a socialist while Rorty is a social democrat. (shrink)

This festschrift includes a dozen essays on issues that have been at the focus of Kai Nielsen's research, mainly issues in ethics and political philosophy. Among these are four essays on socialism and Marxism. There are also essays on philosophy of religion, epistemology, and meta-philosophy.

Drawing on insights of thinkers in the natural rights tradition, Draper analyzes numerous hypothetical cases including those involving a runaway trolley, then seeks to determine if killing civilians in war is ever justified. In his consideration of this issue he avoids appealing to the principle of double effect. Having considered hypothetical cases at length, he leaves it to others to decide if any option to go to war is justifiable. In this regard he himself is sceptical.

Currently, the repetition of a critical way of speaking results in a stagnating tendency in educational debates. This had led to the endeavour of developing a ‘post-critical pedagogy’. This paper employs Rortyan and Latourian language in order to tackle the question of how such a post-critical pedagogy should deal with critique. It argues that if one takes critique as what Latour calls a debunking activity, then post-critical pedagogy should leave critique behind. If however critique means simply to say how something (...) should not be, then post-critical pedagogy should remain critical. In addition, however, there is a need for enriching the critical vocabulary with more affirmative language. For accomplishing this need, in contrast to recent suggestions to go back to ontology, the paper suggests that new propositions developed by literary theorists like Sedgwick and Felski are more promising. All these arguments are framed by Rorty’s notion of philosophy as cultural politics. (shrink)

Ludwig Wittgenstein acknowledges that the Augustinian picture also informed his earlier conception of language. The Augustinian identification of the meaning of a word with the word's referent is accepted only with a further restriction. In the Tractatus, Wittgenstein distinguishes between simple objects and the thereof composed complex objects. This chapter provides a systematic reconstruction of Wittgenstein's sometimes opaque remarks on ostensive definitions and his critique of the Augustinian picture of language. It then addresses the doctrines about names and naming endorsed (...) in the Tractatus. According to the later Wittgenstein the simple ostensive definition of a word, consisting in the utterance of the word accompanied by a pointing gesture, does not unambiguously determine the use of the word. Wittgenstein's arguments can be complemented by the observation that having the same sample is not necessary for two terms to be equivalent either. (shrink)

Duties to future persons are central to numerous key ethical issues including contraception, abortion, genetic selection, treatment of the environment, and population control. Nevertheless, we still seem to be lacking Parfit's 'Theory X', a general theory of beneficence whose appropriateness extends to future generations. Starting from the Golden Rule, R. M. Hare purportedly derived counterintuitive duties to potential people and 'the potentiality principle'. However, I argue that Hare's derivation involves a hidden and unjustifiable extension from TGR, and show how the (...) most plausible form of TGR is compatible with multiple contradictory principles for the treatment of future persons. I appeal to our own preferences to argue that one extension of TGR follows the spirit of TGR, while the other is deeply implausible. Using the plausible extension, I derive a Contingent Interests Principle that offers much promise as Parfit's elusive Theory X. In contrast to Hare's interpretation of TGR, this application provides solid justification for rejecting the potentiality principle. (shrink)

The rule-following paradox of Kripke's Wittgenstein posits that there is no fact of the matter about an individual that can determine whether he means one thing or another by a term, such as "+". The paradox thus renders the existence of meaning illusory. The objective of this thesis is to examine the paradox and try to offer a version of a dispositional account that can counteract Kripke's skeptics. ;Gaining insights from previous dispositionalist accounts of meaning and rule-following, including those of (...) Dretske, Fodor, Millikan, Martin & Heil, Shogenji, and Yallowitz, my project is to put all those insights together to formulate a functional view of human dispositions to rule-following which will resolve the error, finitude, and first-person epistemic problems that Kripke raises against the dispositionalist approach. Specifically, I argue that rule-following or meaning consists in one's possessing a disposition, realistically construed. A rule-following disposition is real in the sense that it is responsible for, and hence not to be equated with, its manifestations under various conditions. A person acquires a real disposition to rule-following through a learning history which is constrained by biologically innate human endowments of learning and cognition. The error problem then becomes the problem of how to identify the disposition without vacuity or circularity. My claim is that identifying a rule-following disposition is a task of scientific hypothesizing, which is epistemically and methodologically sound. The finitude problem is in my view a form of Humean inductive skepticism. My response to it is to adopt a reliabilist theory of justification and its treatment of the induction problem. A distinctive contribution of mine is to offer a functionalist account of dispositions and introspection in the resolution of the first-person epistemic problem. My aim is to do full justice to the phenomenology and epistemology of meaning and rule-following from the first-person point of view. ;My conclusion is that a satisfactory dispositional account such as the one I offer not only vindicates the reality of rule-following and meaning but also increases our understanding of the nature of meaning and human rule-following phenomenon.

Identity, we're told, is the binary relation that every object bears to itself, and to itself only. But how can a relation be binary if it never relates two objects? This puzzled Russell and led Wittgenstein to declare that identity is not a relation between objects. The now standard view is that Wittgenstein's position is untenable, and that worries regarding the relational status of identity are the result of confusion. I argue that the rejection of identity as a binary relation (...) is perfectly tenable. To this end, I outline and defend a logical framework that is not committed to an objectual identity relation but is nevertheless expressively equivalent to first-order logic with identity. After it has thus been shown that there is no indispensability argument for objectual identity, I argue that we have good reasons for doubting the existence of such a relation, and rebut a number of attempts at discrediting these reasons.
