A good argument is one whose conclusions follow from its premises; its conclusions are consequences of its premises. But in what sense do conclusions follow from premises? What is it for a conclusion to be a consequence of premises? Those questions, in many respects, are at the heart of logic (as a philosophical discipline). Consider the following argument: 1. If we charge high fees for university, only the rich will enroll. We charge high fees for university. Therefore, only the rich (...) will enroll. There are many different things one can say about this argument, but many agree that if we do not equivocate (if the terms mean the same thing in the premises and the conclusion) then the argument is valid, that is, the conclusion follows deductively from the premises. This does not mean that the conclusion is true. Perhaps the premises are not true. However, if the premises are true, then the conclusion is also true, as a matter of logic. This entry is about the relation between premises and conclusions in valid arguments. (shrink)

Organ transplantation remains one of modern medicine's remarkable achievements. It saves lives, improves quality of life, diminishes healthcare expenditures in end-stage renal patients, and enjoys high success rates. Yet the promise of transplantation is substantially compromised by the scarcity of organs. The gap between the number of patients on waiting lists and the number of available organs continues to grow. As of January 2006, the combined waiting list for all organs in the United States was 90,284. Unfortunately, thousands of potential (...) organs are lost each year, primarily due to lack of consent to donation from the deceased before death, or from the family thereafter. Only fifty percent of potential donors – the “conversion” rate – become actual donors. The costs attributed to organ shortage are substantial – Medicare paid over $15.5 billion in 2002 for treating patients with end-stage renal-disease, who predominate on organ waiting lists. (shrink)

Obtaining informed consent has typically become a stylized ritual of presenting and signing a form, in which physicians are acting defensively and patients lack control over the content and flow of information. This leaves patients at risk both for being under-informed relative to their decisional needs and of receiving more information than they need or desire. By personalizing the process of seeking and receiving information and allowing patients to specify their desire for information in a prospective manner, we aim to (...) shift genuine control over the informational process to patients. A new paradigm of Information on Demand, such as we suggest, would also enhance legal certainty, achieve greater congruence between the information patients want and the information they receive, and promote more meaningful patient-physician interactions, a desirable outcome that has been difficult to achieve by other means.

In an explicit attempt to reduce physician paternalism and encourage patient participation in making health care decisions, the informed consent doctrine has become a foundational precept in medical ethics and health law. The underlying ethical principle on which informed consent rests — autonomy — embodies the idea that as rational moral agents, patients should be in command of decisions that relate to their bodies and lives. The corollary obligation of physicians to respect and facilitate patient autonomy is reflected in the (...) rules that have been created to implement consent procedures, especially those requiring disclosure of relevant information.However, there are many practical impediments to patient self-determination in health care decisionmaking. Well-meaning physicians often lack the time to live up to the ideal of facilitating genuine, informed deliberation with and by their patients, and many lack the motivation or skill to do so successfully.

As it is known, there is no rule satisfying Additivity in the complete domain of bankruptcy problems. This paper proposes a notion of partial Additivity in this context, to be called µ-additivity. We find that µ-additivity, together with two quite compelling axioms, anonymity and continuity, identify the Minimal Overlap rule, introduced by Neill (1982).

Gil R, Arroyo-Anllo EM, Ingrand P, Gil M, Neau JP, Ornon C, Bonnaud V. Self-consciousness and Alzheimer’s disease. Acta Neurol Scand 2001: 104: 296–300. # Munksgaard 2001. Objectives – To propose a neuropsychological study of the various aspects of self-consciousness (SC) in Alzheimer’s disease. Methods – Forty-five patients with probable mild or moderate AD were included in the study. Severity of their dementia was assessed by the Mini Mental State (MMS). Fourteen questions were prepared to evaluate SC. Results – No (...) significant correlations were found between SC score and educational level, age, and duration of disease. A significant correlation was found between SC score and the severity of dementia, whereas frontal disturbances were just short of the significance threshold. The various aspects of SC were not impaired to the same degree. The most disturbed ones were awareness of cognitive deficiencies, moral judgements and prospective memory. The least disturbed aspects were awareness of identity and of mental representation of the body. Items relating to anosognosia and moral judgements were significantly correlated with the MMS score, whereas affective state, body representation disorders, prospective memory, and capacities for introspection were not related to the severity of the dementia. Consciousness of identity was sound, regardless of MMS score. Conclusions – AD clearly induces an heterogeneous impairment of SC. SC requires a convergence of many neural networks. In AD, neuronal alterations involve many cortical areas and information sent to the associative frontal cortex from memory, language and visuospatial areas is lacking or disturbed. Thus, the sequential order of successive stimuli cannot be maintained by the heteromodal associative cortex (dorsal convexity of the prefrontal cortex), and the supramodal associative cortex (located rostrally in the frontal lobes) is unable to provide reliable monitoring and assessment of simultaneous neural cognitive networks carrying insufficient and inadequate input. The core deficiency in AD patients might be impaired SC equated with the disability to maintain sequential and simultaneous ‘‘attention to life’’. The Self-Consciousness Questionnaire, a clinical scale providing multidimensional measurement, indicates that different aspects of consciousness are not correlated with overall cognitive deficiency as determined by the MMSE.

Organ transplantation has become a proven, cost-effective lifesaving treatment, but its promise is contingent on the number of available organs. The growing gap between the demand and supply results in unnecessary loss and diminished quality of life as well as high costs for surviving patients and health insurers. Twenty years after the enactment of the National Organ Transplantation Act, it is time to rethink the moral basis and overall design of organ transplantation policy. We propose a national plan for organ (...) transplantation insurance under which the federal government would assume responsibility for increasing the organ supply and would cover all costs associated with transplantation for patients not otherwise covered.

In this paper we show that, in Gentzen systems, there is a close relation between two of the main characters in algebraic logic and proof theory respectively: protoalgebraicity and the cut rule. We give certain conditions under which a Gentzen system is protoalgebraic if and only if it possesses the cut rule. To obtain this equivalence, we limit our discussion to what we call regular sequent calculi, which are those comprising some of the structural rules and some logical rules, in (...) a sense we make precise. We note that this restricted set of rules includes all the usual rules in the literature. We also stress the difference between the case of two-sided sequents and the case of many-sided sequents, in which more conditions are needed. (shrink)

Łukasiewicz’s infinite-valued logic is commonly defined as the set of formulas that take the value 1 under all evaluations in the Łukasiewicz algebra on the unit real interval. In the literature a deductive system axiomatized in a Hilbert style was associated to it, and was later shown to be semantically defined from Łukasiewicz algebra by using a “truth-preserving” scheme. This deductive system is algebraizable, non-selfextensional and does not satisfy the deduction theorem. In addition, there exists no Gentzen calculus fully adequate (...) for it. Another presentation of the same deductive system can be obtained from a substructural Gentzen calculus. In this paper we use the framework of abstract algebraic logic to study a different deductive system which uses the aforementioned algebra under a scheme of “preservation of degrees of truth”. We characterize the resulting deductive system in a natural way by using the lattice filters of Wajsberg algebras, and also by using a structural Gentzen calculus, which is shown to be fully adequate for it. This logic is an interesting example for the general theory: it is selfextensional, non-protoalgebraic, and satisfies a “graded” deduction theorem. Moreover, the Gentzen system is algebraizable. The first deductive system mentioned turns out to be the extension of the second by the rule of Modus Ponens. (shrink)

ABSTRACT In this paper we study consequence relations on the set of many sided sequents over a propositional language. We deal with the consequence relations axiomatized by the sequent calculi defined in [2] and associated with arbitrary finite algebras. These consequence relations are examples of what we call Gentzen systems. We define a semantics for these systems and prove a Strong Completeness Theorem, which is an extension of the Completeness Theorem for provable sequents stated in [2]. For the special case (...) of the finite linear MV-algebras, the Strong Completeness Theorem was proved in [10], as a consequence of McNaughton's Theorem. The main tool to prove this result for arbitrary algebras is the deduction-detachment theorem for Gentzen systems. (shrink)

El actual discurso social sobre el mal es obsoleto e ineficaz. Vivimos bajo presupuestos cognitivos (parcialmente) fallidos que se resisten a sucumbir porque están en juego necesidades psicológicas unidas a un determinado concepto del ser humano, de Dios (o de lo que se esconde tras esta idea para los ateos) y de la realidad. Este artículo trata de desarrollar un nuevo enfoque del problema-enigma del mal que pone en cuestión diez paradigmas dominantes, planteando la necesidad de reconocer su existencia (en (...) torno al concepto de exceso) como requisito para plantarle cara como única opción moral, la de luchar con todas las armas disponibles, incluido un saber que aspira a relacionar e integrar diversos saberes en torno a un único objetivo: derrotar el mal o al menos intentarlo.

I argue that (1) the accusation that psychological methods are too diverse conflates “reliability” with “validity”; (2) one must not choose methods by the results they produce – what matters is whether a method acceptably models the real-world situation one is trying to understand; (3) one must also distinguish methodological failings from differences that arise from the pursuit of different theoretical questions.

El artículo ofrece una reflexión personal sobre los principios de la bioética. El tiempo de los derechos exige su positivización: es un riesgo y una oportunidad. El autor analiza la situación actual y señala la fragilidad de los principios por su indeterminación. Muestra el proceso de positivización y concluye que los principios deben ser positivizados y las reglas formuladas de acuerdo con los principios. Como en los juegos de suma cero si las reglas ganan, los principios pierden. Parece que los (...) principios son víctimas de su éxito. Sin embargo, el triunfo de los principios, su transformación en reglas no anula, sino que refuerza los principios. (shrink)

When considering m-sequents, it is always possible to obtain an m-sequent calculus VL for every m-valued logic (defined from an arbitrary finite algebra L of cardinality m) following for instance the works of the Vienna Group for Multiple-valued Logics. The Gentzen relations associated with the calculi VL are always finitely equivalential but might not be algebraizable. In this paper we associate an algebraizable 2-Gentzen relation with every sequent calculus VL in a uniform way, provided the original algebra L has a (...) reduct that is a distributive lattice or a pseudocomplemented distributive lattice. We also show that the sentential logic naturally associated with the provable sequents of this algebraizable Gentzen relation is the logic that preserves degrees of truth with respect to the original algebra (in contrast with the more common logic that merely preserves truth). Finally, for some particular logics we obtain 2-sequent calculi that axiomatize the algebraizable Gentzen relations obtained so far. (shrink)

Children who experience well-being are engaging more confidently and positively with their caregiver and peers, which helps them to profit more from available learning opportunities and support current and later life outcomes. The goodness-of-fit theory suggests that children’s well-being might be a result of the interplay between their temperament and the environment. However, there is a lack of studies that examined the association between children’s temperament and well-being in early childhood education and care, and whether this association is affected by (...) ECEC process quality. Using a multilevel random coefficient approach, this study examines the association between toddlers’ temperament and well-being in Norwegian ECEC and investigates whether process quality moderates this association. Results reveal an association between temperament and well-being. Staff-child conflict moderates the association between shyness and well-being, and between activity and well-being. Moreover, high emotional behavioral support moderates the association between activity and well-being. Extra attention should be paid by the staff to these children’s needs. (shrink)

We consider Sussman et al. 's suggestion that auditory biases for processing low-noise relationships among pairs of acoustic variables is a preadaptation for human speech processing. Data from other animal communication systems, especially those involving sexual selection, also suggest that neural biases in the receiver system can generate strong selection on the form of communication signals.

Impairment of the Self has been described in frontal–temporal dementia but little research has been carried out in patients with Alzheimer’s disease. Objective. The aim of this study was to explore changes in the self in patients with AD. Method. Forty-seven patients with mild to moderate AD were examined using a semi-structured scale designed to assess the self-concept along three dimensions, namely, the Material Self, the Social Self and the Spiritual Self. Results. The majority of patients presented impairment of at (...) least one dimension of the Self. When only one dimension was affected, it was always the Social Self. The severity of impairment of the Self was correlated to the impairment of the semantic autobiographical memory and apathy. The Self is impaired in AD and the Social Self dimension appears to be more vulnerable in AD than other dimensions. (shrink)

The Gait Deviation Index is a multivariate measure of overall gait pathology based on 15 gait features derived from three-dimensional kinematic data. GDI aims at providing a comprehensive, easy to interpret, and clinically meaningful metric of overall gait function. It has been used as an outcome measure to study gait in several conditions: cerebral palsy, post-stroke hemiparetic gait, Duchenne muscular dystrophy, and Parkinson’s disease, among others. Nevertheless, its use in population with Spinal Cord Injury has not been studied yet. The (...) aim of the present study was to investigate the applicability of the GDI to SCI through the assessment of the relationship of the GDI with the Walking Index for Spinal Cord Injury II. 3D gait kinematics of 34 patients with incomplete SCI was obtained. Besides, 3D gait kinematics of a sample of 50 healthy volunteers was also gathered with Codamotion motion capture system. A total of 302 and 446 strides were collected. GDI was calculated for each stride and grouped for each WISCI II level. HV data were analyzed as an additional set. Normal distribution for each group was assessed with Kolmogorov-Smirnov tests. Afterward, ANOVA tests were performed between each pair of WISCI II levels to identify differences among groups. The results showed that the GDI was normally distributed across all WISCI II levels in both iSCI and HV groups. Furthermore, our results showed an increasing relationship between the GDI values and WISCI II levels in subjects with iSCI, but only discriminative in WISCI II levels 13, 19, and 20. The index successfully distinguished HV group from all the individuals with iSCI. Findings of this study indicated that the GDI is not an appropriate multivariate walking metric to represent the deviation of gait pattern in adult population with iSCI from a normal gait profile when it is compared with the levels of walking impairment described by the WISCI II. Future work should aim at defining and validating an overall gait index derived from 3D kinematic gait variables appropriate for SCI, additionally taking into account other walking ability outcome measures.

Humanist sociologists are activists rooted in the reality of history and change and guided by a concern for the 'real life' problems of equality, peace, and social justice. They view people as active shapers of social life, capable of creating societies in which everyone's potential can unfold. Alfred McClung Lee introduces this volume with 'Sociology: Humanist and Scientific' and develops the theme that a sociology that is humanist is also scientific. The other nine selections are grouped into four parts: 'The (...) Individual and Social Life;' 'Social Institutions: Technology, Science, and Formal Organization;' 'Political Structures: Issues of Justice and Equality;' and 'Methodological Critiques and Counterproposals.'.

From the most prominent thinkers in Latin American philosophy, literature, politics, and social science comes a challenge to conventional theories of globalization. The contributors to this volume imagine a discourse in which revolution requires no temporalized march of progress or takeovers of state power but instead aims at local control and the material conditions for human dignity.

Orbis Sensualium Pictus by Comenius is historical evidence of the revolutionary development of language didactic in the seventeenth century. However, this book is not only a simple encyclopedic Latin study book with pictures, but a little theology work containing Christian cosmological universalism as well as a pedagogy which provides principles for educational practice and social realizations of a theological ideal in a very new and creative form of iconography. While studying Latin seems to be the main purpose of his work, (...) the authentic intention of the author lies in a panpedagogical call to a religious-educational mission for rebuilding humanity and society during and after the 30 Years War. In this article, we will show the historical and pedagogical meaning of this book through component analysis, framework analysis and iconographical interpretation. In addition, we will also approach Comenius’ concept of Pampaedia through an iconographical shortcut, highlighting a picture in “Invitatio” and “Clausula”, which is presented twice in this book.

Is there a relation of logical consequence in natural language? Logicality, in the philosophical literature, has been conceived of as a restrictive phenomenon that is at odds with the unbridled richness and complexity of natural language. This article claims that there is a relation of logical consequence in natural language, and moreover, that it is the subject matter of the bulk of current theories of formal semantics. I employ the framework of _semantic constraints_ (Sagi in Log Anal 57(227):259–276, 2014), which (...) generalizes the Tarskian definition of logical consequence. I apply the widely accepted criterion of invariance under isomorphisms (Sher in J. Symb Log 61(2):653–686, 1996) generalized to the framework of semantic constraints (Sagi in Bull Symb Log 28(1):104–132, 2022b), combined with a theory of Glanzberg (in Metasemantics: new essays on the foundations of meaning, 2014) to delineate the relation of logical consequence in natural language.

To commemorate 40 years since the founding of the Journal of Business Ethics, the editors-in-chief of the journal have invited the editors to provide commentaries on the future of business ethics. This essay comprises a selection of commentaries aimed at creating dialog around the theme Bringing Excitement to Empirical Business Ethics Research (inspired by the title of the commentary by Babalola and van Gils). These editors, considering the diversity of empirical approaches in business ethics, envisage a future in which quantitative (...) business ethics research is more bold and innovative, as well as reflexive about its techniques, and dialog between quantitative and qualitative research nourishes the enrichment of both. In their commentary, Babalola and van Gils argue that leadership research has stagnated with the use of too narrow a range of perspectives and methods and too many overlapping concepts. They propose that novel insights could be achieved by investigating the lived experience of leadership (through interviews, document analysis, archival data); by focusing on topics of concern to society; by employing different personal, philosophical, or cultural perspectives; and by turning the lens on the heroic leader (through “dark-side” and follower studies). Taking a provocative stance, Bal and Garcia-Lorenzo argue that we need radical voices in current times to enable a better understanding of the psychology underlying ethical transformations. Psychology can support business ethics by not shying away from grander ideas, going beyond the margins of “unethical behaviors harming the organization” and expanding the range of lenses used to studying behavior in context. In the arena of finance and business ethics, Guedhami, Liang, and Shailer emphasize novel data sets and innovative methods. Significantly, they stress that an understanding the intersection of finance and ethics is central to business ethics; financial equality and inclusion are persistent socio-economic and political concerns that are not always framed as ethics issues, yet relevant business policies and practices manifest ethical values. Finally, Charles Cho offers his opinion on the blurry line between the “ethical” versus “social” or “critical” aspects of accounting papers. The Journal of Business Ethics provides fertile ground for innovative, even radical, approaches to quantitative methods (see Zyphur and Pierides in J Bus Ethics 143(1):1–16, https://doi.org/10.1007/s10551-017-3549-8, 2017), as part of a broad goal of ethically reflecting on empirical research.
