Patients in a vegetative state/ unresponsive wakefulness syndrome (VS/UWS) pose ethical dilemmas to those involved. Many conflicts occur between professionals and families of these patients. In the Netherlands physicians are supposed to withdraw life sustaining treatment once recovery is not to be expected. Yet these patients have shown to survive sometimes for decades. The role of the families is thought to be important. The aim of this study was to make an inventory of the professional perspective on conflicts in long-term (...) care of patients in VS/UWS. A qualitative study of transcripts on 2 Moral Deliberations (MD’s) in 2 cases of patients in VS/UWS in long-term care facilities. Six themes emerged: 1) Vision on VS/UWS; 2) Treatment and care plan; 3) Impact on relationships; 4) Feelings/attitude; 5) Communication; 6) Organizational aspects. These themes are related to professionals and to what families had expressed to the professionals. We found conflicts as well as contradictory feelings and thoughts to be a general feature in 4 of these themes, both in professionals and families. Conflicts were found in several actors: within families concerning all 6 themes, in nurse teams concerning the theme treatment and care plan, and between physicians concerning all 6 themes. Different visions, different expectations and hope on recovery, deviating goals and contradictory feelings/thoughts in families and professionals can lead to conflicts over a patient with VS/UWS. Key factors to prevent or solve such conflicts are a carefully established diagnosis, clarity upon visions, uniformity in treatment goals and plans, an open and empathic communication, expertise and understanding the importance of contradictory feelings/thoughts. Management should bridge conflicts and support their staff, by developing expertise, by creating stability and by facilitating medical ethical discourses. Shared compassion for the patient might be a key to gain trust and bridge the differences from non-shared to shared decision making. (shrink)

I argue that David Lewis is too quick to deny the presentist the right to employ span operators. There is no reason why the presentist could not help herself to both primitive tensed slice operators and primitive span operators. She would then have another device available to eliminate ambiguities and explain why sentences with embedded contradictions may nevertheless be true.

Much of cognitive psychology focuses on effects measured in tens of milliseconds while significant educational outcomes take tens of hours to achieve. The task of bridging this gap is analyzed in terms of Newell's (1990) bands of cognition—the Biological, Cognitive, Rational, and Social Bands. The 10 millisecond effects reside in his Biological Band while the significant learning outcomes reside in his Social Band. The paper assesses three theses: The Decomposition Thesis claims that learning occurring at the Social Band can be (...) reduced to learning occurring at lower bands. The Relevance Thesis claims that instructional outcomes at the Social Band can be improved by paying attention to cognition at the lower bands. The Modeling Thesis claims that cognitive modeling provides a basis for bridging between events on the small scale and desired outcomes on the large scale. The unit-task level, at the boundary of the Cognitive and Rational Bands, is useful for assessing these theses. There is good evidence for all three theses in efforts that bridge from the unit-task level to educational applications. While there is evidence for the Decomposition Thesis all the way down to the 10 millisecond level, more work needs to be done to establish the Relevance Thesis and particularly the Modeling Thesis at the lower levels.

Moral pluralism is the norm in contemporary society. Even the best philosophical arguments rarely persuade moral opponents who differ at a foundational level. This has been vividly illustrated in contemporary debates in bioethics surrounding contentious issues such as abortion and euthanasia. It is readily apparent that bioethics discourse lacks an empirical explanation for the broad differences about various topics in bioethics and health policy. In recent years, social and cognitive psychology has generated novel approaches for defining basic differences in moral (...) intuitions generally. We propose that if empirical research using social intuitionist theory explains why people disagree with one another over moral issues, then the results of such research might help people debate their moral differences in a more constructive and civil manner. We illustrate the utility of social intuitionism with data from a national physician survey. (shrink)

Arthur Prior states that ‘It will be/was/is that p’ is true iff ‘p’ will be/was/is true, and that is all that needs to be said about the matter. This appears to avoid any need to invoke the existence of non-present entities and accounts for tensed truths with very little ontological cost. However, as David Lewis notes, this version of presentism gives the wrong results when applied to numerically quantified tensed propositions. I show how presentism can accommodate numerical quantification by introducing (...) a more appropriate tense operator. Further, I argue that it is implausible to think that we can have a primitive understanding of it; the correct semantics involves quantification over past and future times. I go on to show what kind of ontology can complement this semantic story, whilst remaining presentist in nature. (shrink)

Though the current research stream has provided some risk factors for envy at the workplace, little is still known about the drivers and consequences of envy. Based on Vecchio’s theory, this study investigates the ripple effect of the span of supervision on envy. Moreover, it sheds light on the moderating role of meaningful work in their relationship. The data comprising sample size 439 were collected from confrères of four fast food companies listed on the Stock Exchange of Pakistan. Partial (...) Least Square Structural Equation Modeling technique was implemented through SmartPLS 3.3.2 to analyze the measurement and structural relationships. The results demonstrate that a narrow span of supervision will increase work engagement, and reduce instigated incivility via decreasing envy and resource depletion in sequence. Moreover, meaningful work would help regulate the inimical stream of dénouement of envy. Theoretical and practical implications, along with the limitations and future directions, have also been discussed. (shrink)

This study investigated the effects of music therapy and pictorial illustration on the attention span of children with mild intellectual difficulties. A pre-test, post-test and control group quasi-experimental research design was used with a sample of children diagnosed with mild intellectual disability from three special schools in Ibadan, Nigeria. Fifty children were randomly selected and assigned to one of three groups: music therapy, pictorial illustration, or control. Twenty-four sessions of music therapy and pictorial illustration classes were held with the (...) experimental group only. The Moss Attention Rating Scale was used before and after the intervention to collect data on participants’ attention span. Analysis of Covariance indicated that there was a significant statistical difference between pre-test and post-test results of the two groups. The estimated marginal means of post-attention span by treatment indicated that pictorial illustration had the highest post-attention span score, followed by music therapy, while post-attention span score for the control group was the least. Based on the findings, it is recommended that teachers, caregivers, and parents of children with mild intellectual disability adopt pictorial illustration and music therapy as teaching strategies to enhance their attention span.

Two theorems are proved: First that the statement“there exists a field F such that for every vector space over F, every generating set contains a basis”implies the axiom of choice. This generalizes theorems of Halpern, Blass, and Keremedis. Secondly, we prove that the assertion that every vector space over ℤ2 has a basis implies that every well-ordered collection of two-element sets has a choice function.

This article combines Social Choice Theory with Discrete Optimization. We assume that individuals have preferences over edges of a graph that need to be aggregated. The goal is to find a socially “best” spanning tree in the graph. As ranking all spanning trees is becoming infeasible even for small numbers of vertices and/or edges of a graph, our interest lies in finding algorithms that determine a socially “best” spanning tree in a simple manner. This problem is closely related to the (...) minimum (or maximum) spanning tree problem in Discrete Optimization. Our main result shows that for the various underlying ranking rules on the set of spanning trees discussed in this article, the sets of “best” spanning trees coincide. Moreover, a greedy algorithm based on a transitive group ranking on the set of edges will always provide such a “best” spanning tree. (shrink)

Sexual boundary violations can negatively impact the culture of safety within a medical practice or healthcare institution and severely compromise the covenant of care and physician objectivity. Lack of education and training is one factor associated with physician misconduct that leads to high financial and personal cost. This paper presents a follow-up study of physicians referred to a professional development course in 2001 and presents demographic data from 2001 to present. The paper focuses on the education and remediation progress regarding (...) sexual misconduct by physicians. (shrink)

An absolute decline in US life expectancy in low education whites has alarmed policy makers and attracted media attention. Depending on which studies are correct, low education white women have lost between 3 and 5 years of lifespan; men, between 6 months and 3 years. Although absolute declines in life expectancy are relatively rare, some commentators see the public alarm as reflecting a racist concern for white lives over black ones. How ought we ethically to evaluate this lifespan contraction in (...) low education whites? Should we care, or is it racist to care? Does it constitute an injustice or reflect justice being done? I argue that the lifespan contraction in low education whites violates key normative criteria used to make determinations of health justice, and that these judgments do not vitiate concerns about racism. I conclude with reflections on US population health policy and building an inclusive health equity movement. (shrink)

This interpretation directed at certain passages in Plato’s Theaetetus explicates the close relation that the dialogue establishes between memory, thought, and speech. It shows that all of these means contribute to the soul’s capacity to stretch beyond mere perceptions. The interpretation also shows that comedic elements play a major role in the dialogue, most notably, in the well-known passage that purportedly explains knowledge and memory by means of the image of birds flying about in an aviary. Through close examination of (...) the relevant passages, the interpretation shows that the Theaetetus is not aporetic but rather achieves a positive advance that prepares the way for the Sophist.

Clustering plays an important role in data mining, pattern recognition, and machine learning. Then, single-valued neutrosophic sets are a useful means to describe and handle indeterminate and inconsistent information, which fuzzy sets and intuitionistic fuzzy sets cannot describe and deal with. To cluster the data represented by single-value neutrosophic information, the article proposes a single-valued neutrosophic minimum spanning tree clustering algorithm. Firstly, we defined a generalized distance measure between SVNSs. Then, we present an SVNMST clustering algorithm for clustering single-value neutrosophic (...) data based on the generalized distance measure of SVNSs. Finally, two illustrative examples are given to demonstrate the application and effectiveness of the developed approach. (shrink)

In this paper, I would like to introduce a complexity in the debate on the meaning of religion today. This complexity relates to the tension between an internal and an external perspective on religion. I will try to show how the disagreement between some protagonists in the debate and also the difficulties these protagonists face can be clarified by taking into account the difference between both perspectives. In the first part I discuss Marcel Gauchet’s view on the meaning of religion (...) today. In the second part I confront Gauchet with an ambiguity in his definition of religion. This ambiguity can also be found in Gauchet’s discussion with Luc Ferry, although neither Gauchet nor Ferry are capable of adequately dealing with the problem. This is because both authors are bound to an external perspective on religion, which doesn’t allow them to distinguish its specific content from other forms of meaningfulness. This is why we will concentrate in the third part on Taylor’s internal approach to religion. However, in the fourth part, we will demonstrate how such an approach is in tension with the normative ambitions Taylor seems to cherish. (shrink)

We propose a modular ontology of the dynamic features of reality. This amounts, on the one hand, to a purely spatial ontology supporting snapshot views of the world at successive instants of time and, on the other hand, to a purely spatiotemporal ontology of change and process. We argue that dynamic spatial ontology must combine these two distinct types of inventory of the entities and relationships in reality, and we provide characterizations of spatiotemporal reasoning in the light of the interconnections (...) between them.

Any inquiry into the meaning and implications of the prolongation of the human lifespan requires an investigation of its metaphysical basis and its ethical outcomes. This chapter explains a series of metaphysical and ethical claims about lifespan extension. It highlights a number of arguments that are typically put forward against these claims, and shows the ways in which they are mistaken. Two such claims given in the chapter are: (1) aging and life stages are neither wholly constituted by biological givens, (...) nor wholly understandable in terms of biological parameters; instead, aging and life stages are, in crucial ways, socially constructed; and (2) death is bad, and other things being equal, a longer life is a better life.

Let G V, E be a simple undirected complete graph with vertex and edge sets V and E, respectively. In this paper, we consider the degree-constrained k -minimum spanning tree problem which consists of finding a minimum cost subtree of G formed with at least k vertices of V where the degree of each vertex is less than or equal to an integer value d ≤ k − 2. In particular, in this paper, we consider degree values of d ∈ (...) 2,3. Notice that DC k MST generalizes both the classical degree-constrained and k -minimum spanning tree problems simultaneously. In particular, when d = 2, it reduces to a k -Hamiltonian path problem. Application domains where DC k MST can be adapted or directly utilized include backbone network structures in telecommunications, facility location, and transportation networks, to name a few. It is easy to see from the literature that the DC k MST problem has not been studied in depth so far. Thus, our main contributions in this paper can be highlighted as follows. We propose three mixed-integer linear programming models for the DC k MST problem and derive for each one an equivalent counterpart by using the handshaking lemma. Then, we further propose ant colony optimization and variable neighborhood search algorithms. Each proposed ACO and VNS method is also compared with another variant of it which is obtained while embedding a Q-learning strategy. We also propose a pure Q-learning algorithm that is competitive with the ACO ones. Finally, we conduct substantial numerical experiments using benchmark input graph instances from TSPLIB and randomly generated ones with uniform and Euclidean distance costs with up to 400 nodes. Our numerical results indicate that the proposed models and algorithms allow obtaining optimal and near-optimal solutions, respectively. Moreover, we report better solutions than CPLEX for the large-size instances. Ultimately, the empirical evidence shows that the proposed Q-learning strategies can bring considerable improvements.

This paper focuses on the cognitive/computational and evolutionary levels. It describes three proposals to make cognition computationally tractable, namely: Resource Rationality, the Adaptive Toolbox and Massive Modularity. While each of these proposals appeals to evolutionary considerations to dissolve the intractability of cognition, Rich, Blokpoel, de Haan, and van Rooij argue that, in each case, the intractability challenge is not resolved, but just relocated to the level of evolution.

This article discusses interactive minimum cost spanning tree problems and argues that the standard approach of using a transferable utility game to come up with a fair allocation of the total costs has some flaws. A new model of spillover games is presented, in which each player’s decision whether or not to cooperate is properly taken into account.

This article aims to develop a new account of scientific explanation for computer simulations. To this end, two questions are answered: what is the explanatory relation for computer simulations? And what kind of epistemic gain should be expected? For several reasons tailored to the benefits and needs of computer simulations, these questions are better answered within the unificationist model of scientific explanation. Unlike previous efforts in the literature, I submit that the explanatory relation is between the simulation model and the (...) results of the simulation. I also argue that our epistemic gain goes beyond the unificationist account, encompassing a practical dimension as well. (shrink)

Research into the mechanisms of aging has suggested the possibility of extending the human life span. But there may be evolutionary biological reasons for senescence and the limits of the cell cycle that explain the infirmities of aging and the eventual demise of all human organisms. Genetic manipulation of the mechanisms of aging could over many generations alter the course of natural selection and shift the majority of deleterious mutations in humans from later to earlier stages of life. This (...) could harm people in the distant future by making them more susceptible to premature disease and mortality. Thus there are biological and moral reasons to carefully consider the implications of exploiting this technology on a broad scale to extend the lives of people in the present and near future.
