The Second Vatican Council has a special significance in Latin America. This is especially true due to the influence of the document Gaudium et Spes. This took place at the Medellín Conference when Bishop Marcus Gregorio McGrath, C.S.C., pointed to this influence through his keynote address “The Signs of the Times.” He was prepared for this moment through his earlier theological training in Europe and his pastoral missions, especially in Chile and Panama. It was his earlier practice of Catholic (...) Action among young lay persons that led him into the “bridge theology” that was to be promoted further by Pope Francis. (shrink)

Civility is an essential feature of health care, as it is in so many other areas of human interaction. The article examines the meaning of civility, reviews its origins, and provides reasons for its moral significance in health care. It describes common types of uncivil behavior by health care professionals, patients, and visitors in hospitals and other health care settings, and it suggests strategies to prevent and respond to uncivil behavior, including institutional codes of conduct and disciplinary procedures. The article (...) concludes that uncivil behavior toward health care professionals, patients, and others subverts the moral goals of health care and is therefore unacceptable. Civility is a basic professional duty that health care professionals should embrace, model, and teach. (shrink)

Publisher's description: The New Dictionary of Christian Apologetics is a must-have resource for professors and students, pastors and laypersons - in short, for any Christian who wishes to understand or develop a rational explanation of the Christian faith in the context of today's complex and ever-changing world. Including hundreds of articles that cover key topics, historic figures and contemporary global issues relating to the study and practice of Christian apologetics, this handy one-volume resource will make an invaluable addition to any (...) Christian library. The dictionary is divided into two parts: Part one offers a series of introductory essays that set the framework for the dictionary. These essays examine the practice and importance of Christian apologetics in light of theological, historical and cultural concerns. Part two builds on these essays to present numerous alphabetized articles on individuals, ideas, movements and disciplines that are vital to a rational explanation of the Christian faith. Both essays and articles are written by leading Christian philosophers and theologians. Together, they form an indispensable resource for Christians living in today's pluralistic age. (shrink)

This study explores how distributing the controls of a video game among multiple players affects the sociality and engagement experienced in game play. A video game was developed in which the distribution of game controls among the players could be varied, thereby affecting the abilities of the individual players to control the game. An experiment was set up in which eight groups of three players were asked to play the video game while the distribution of the game controls was increased (...) in three steps. After each playing session, the players’ experiences of sociality and engagement were assessed using questionnaires. The results showed that distributing game control among the players increased the level of experienced sociality and reduced the level of experienced control. The game in which the controls were partly distributed led to the highest levels of experienced engagement, because the game allowed social play while still giving the players a sense of autonomy. The implications for interaction design are discussed. (shrink)

The extent to which game play is experienced as engaging is an important criterion for the playability of video games. This study investigates how video games can be designed towards increased levels of experienced engagement over time. For this purpose, two experiments were conducted in which a total of 35 participants repeatedly played a video game. Results indicate that experienced engagement is based on the extent to which the game provides rich experiences as well as by the extent to which (...) the game provides a sense of control. In view of the influence of both game features and players’ expertise on the levels of experienced richness and control, it is concluded that game features should be modified over time to maintain optimal levels of engagement.

Causal relations among components and activities are intentionally misrepresented in mechanistic explanations found routinely across the life sciences. Since several mechanists explicitly advocate accurately representing factors that make a difference to the outcome, these idealizations conflict with the stated rationale for mechanistic explanation. We argue that these idealizations signal an overlooked feature of reasoning in molecular and cell biology—mechanistic explanations do not occur in isolation—and suggest that explanatory practices within the mechanistic tradition share commonalities with model-based approaches prevalent in population (...) biology.

Inductive reasoning aims at constructing rules and models of general applicability from a restricted set of observations. Induction is a keystone in natural sciences, and it influences diverse application fields such as engineering, medicine and economics. More generally, induction plays a major role in the way humans learn and operate in their everyday life. The level of reliability that a model achieves depends on how informative the observations are relative to the flexibility of the process by which the model is (...) constructed. When the process is articulated so that the model can incorporate descriptive details and subtleties, a large set of informative observations are required to reliably tune the model, whereas models obtained from simple procedures can be tuned with fewer observations. This article introduces the concept of “dominance”, which refers to the situation in which a reduced subset of observations suffices to reconstruct the model. A mathematical framework is presented to quantify the reliability of learning procedures as a function of the size of the subset of dominant observations. Although limited in scope, we believe that our study can contribute to the understanding of some fundamental mechanisms by which knowledge is generated from observations in inductive reasoning.

High-dose chemotherapy and autologous stem cell transplantation is used to treat some advanced malignancies. It is a traumatic procedure, with a high complication rate and significant mortality. ASCT patients and their carers draw on many sources of information as they seek to understand the procedure and its consequences. Some seek information from beyond orthodox medicine. Alternative beliefs and practices may conflict with conventional understanding of the theory and practice of ASCT, and ‘contested understandings’ might interfere with patient adherence to the (...) strict and demanding protocols required for successful ASCT.The present study, conducted in Sydney, Australia, examines narrative-style interviews with 10 sequentially recruited ASCT patients and nine of their carers conducted at the time of transplant and three months later. Transcripts were read for instances of mention of alternative advice, and for instances of contested understanding of information relevant to the transplant.Patients and carer pairs expressed closely concordant views about alternative advice. Five pairs were consulting alternative practitioners. Contested understanding was expressed in four domains—understandings of the transplant itself and its underlying theory, of the relationship between the components of the ‘transplant’, of the nature and role of stem cells, and of beliefs about bodily function and life-style. Contested understandings of the transplant treatment were expressed as predominantly personal interpretations of orthodox informationPatients and carers seemed to recognise that alternative and conventional systems were discordant, yet they were able to separate the two, and adhere to each practice without prejudicing their medical treatment. A single case of late, post-transplant repudiation of Western medicine is discussed to emphasise some of the possible determinants of dissonance when it does occur. (shrink)

As a reply to the commentary (Humphreys in Found Sci, 2012), we explore the methodological implications of seeing artificial neural networks as generic classification tools, we show in which sense the use of descriptions and models in data analysis is not equivalent to the original empirical use of epicycles in describing planetary motion, and we argue that agnostic science is essentially related to the type of problems we ask about a phenomenon and to the processes used to find answers.

As a reply to the commentary (Lenhard in Found Sci, 2012), we stress here that structural understanding of data analysis techniques is the natural counterpart to the lack of understanding of phenomena in agnostic science. We suggest moreover that the dynamics of computational processes, and their parallels with the dynamics of natural processes, will increasingly be, possibly, the driving force of the development of data analysis.

It is often assumed that graphemes are a crucial level of orthographic representation above letters. Current connectionist models of reading, however, do not address how the mapping from letters to graphemes is learned. One major challenge for computational modeling is therefore developing a model that learns this mapping and can assign the graphemes to linguistically meaningful categories such as the onset, vowel, and coda of a syllable. Here, we present a model that learns to do this in English for strings (...) of any letter length and any number of syllables. The model is evaluated on error rates and further validated on the results of a behavioral experiment designed to examine ambiguities in the processing of graphemes. The results show that the model (a) chooses graphemes from letter strings with a high level of accuracy, even when trained on only a small portion of the English lexicon; (b) chooses a similar set of graphemes as people do in situations where different graphemes can potentially be selected; (c) predicts orthographic effects on segmentation which are found in human data; and (d) can be readily integrated into a full-blown model of multi-syllabic reading aloud such as CDP++ (Perry, Ziegler, & Zorzi, 2010). Altogether, these results suggest that the model provides a plausible hypothesis for the kind of computations that underlie the use of graphemes in skilled reading. (shrink)

-/- In this article I deal with the question “How could we renew and enrich computer technology with Kant's help?”. By this I would like to invite computer scientists and engineers to initiate or intensify their cooperation with Kant experts. -/- What I am looking for is a better “method of definition” for software systems, particularly for the development of object-oriented and knowledge-based systems. -/- After a description of the “software crisis”, I deal first with the question why this crisis (...) could not yet be overcome. A way out of this software crisis can be expected from systems which are adapted to the human faculty of thinking. I show which foundation is in my opinion necessary and sketch the principles according to which a “human-centred” method of definition for sych systems could be developed on that foundation with Kant's help.

We propose an approach to designing smart wearables that act as partners to help people cope with stress in daily life. Our approach contributes to the developing field of smart wearables by addressing how technological capabilities can be designed to establish partnerships that consider the person, the situation, and the appropriate type of support. As such, this study also contributes to healthcare by opening up novel technology-supported routes to stress treatment and care. We present the results of a phenomenological study (...) conducted with three war veterans who suffer from chronic posttraumatic stress disorder. We describe how their experiences of dealing with their stress informed our design approach, and discuss the implications of these results on smart wearables and stress management in general. We conclude by reflecting on the limitations of this study and directions for future work. (shrink)

Alister McGrath has written to great acclaim on both Richard Dawkins and C. S. Lewis. Here he brings these two intriguing and well-known writers into a conversation. They could hardly have more different perspectives! Engaging with their views is a brilliant way of sharpening up our own thinking on the meaning of life.

There are few successful applications of automated reasoning over OWL-formalised bio-ontologies, and requirements are often unclearly formulated. Of what is available, usage and prospective scenarios of automated reasoning is often different from the straightforward classification and satisfiability. We list nine types of scenarios and specify the requirements in more detail. Several of these requirements are already possible in practice or at least in theory, others are in need of further research, in particular regarding the linking of the OWL ontology to (...) data, reasoning over roles, and dynamically linking modular ontologies.

ZusammenfassungFünfzehn Jahre nach ihrer Entstehung ist die Neuroethik ein internationales wissenschaftliches Feld mit enormer Dynamik. Innerhalb weniger Jahre wurden eigene Kongresse, Zeitschriften, Forschungsförderprogramme, Fachgesellschaften und Institute gegründet. Gleichwohl besteht erheblicher Dissens über die Definition und den Gegenstandsbereich dieses neuen Gebiets. Wir argumentieren hier für eine differenzierte Konzeption, wonach neben der Reflexion ethischer Probleme der Neurowissenschaft und ihrer überwiegend neurotechnologischen Anwendungen auch die ethische Reflexion neurowissenschaftlicher Forschung zur Moralität zur Neuroethik gehört. Dies umfasst zwar nicht neurowissenschaftliche oder neuropsychologische Studien zur Moralität, (...) wohl aber die Reflexion der Bedeutung dieser Forschung für die Ethik und das Recht. Wir geben einen Überblick über die wichtigsten Themen der Neuroethik, woraus deutlich wird, wie sehr in verschiedenen gesellschaftlichen Bereichen, auch jenseits von Medizin und Gesundheitswesen, neuroethische Fragen relevant sind. Das Potenzial der Neuroethik als eines neuen Wissenschaftsfeldes liegt darin, durch eine Verknüpfung neurophilosophischer und medizinethischer Themen sowie eine breite interdisziplinäre Vernetzung neue Antworten auf gesellschaftlich drängende Fragen zu finden.

There was a time when moral philosophy -- particularly Christian, and even more particularly Roman Catholic, moral philosophy -- was happily conceived of as a 'science' in which virtually everything could be deduced from a limited number of absolutes. There are moral philosophers who still spend a lifetime doing just this, but their philosophy becomes increasingly inadequate to cope with the new human understandings that have broken in on the world. Absolutist language and ethics can no longer be accepted with (...) the easy assurance they once were. The author discusses the leading moral philosophers of the Anglo-Saxon School, setting out their views clearly and fairly, and criticizing always in a positive and constructive manner. Among those he discusses are A.J. Ayer, Kurt Baier, R.M. Hare, P.H. Nowell-Smith, C.L. Stevenson, Stephen Toulmin and J.O. Urmson. (shrink)

This paper takes a bottom-up approach to empirically investigate how people construct the meaning of obscenity, and offers an experientialist, cognitive linguistic account to explain why the term appears to defy definition and makes a problematic legal concept. To study the contextual dependence of the term, we examined the extent to which various item characteristics (such as genre, context, and the race or celebrity status of the people portrayed) and individual variables (such as gender, religion, sexual orientation and previous personal (...) and cultural experiences) influence our perception of seemingly obscene materials. We report correlations that have not been previously shown. The data support the thesis that the meaning of obscenity emerges in a cognitive-affective response that arises during a dynamic process of interpretation, and thus allows for extralegal factors to influence judgment. The results challenge the assumption that obscenity is a symbolic representation of objectively existing reality and argue that community standard of obscenity is a legal fiction. (shrink)
