Prenatal screening for foetal abnormalities such as Down's syndrome differs from other forms of population screening in that the usual aim of achieving health gains through treatment or prevention does not seem to apply. This type of screening leads to no other options but the choice between continuing or terminating the pregnancy and can only be morally justified if its aim is to provide meaningful options for reproductive choice to pregnant women and their partners. However, this aim should not be (...) understood as maximizing reproductive choice per se. Only if understood as allowing prospective parents to avoid suffering related to living with serious disorders and handicaps can prenatal screening be a publicly or collectively funded programme. The alternative of moving prenatal testing outside the healthcare system into the private sector is problematic, as it makes these tests accessible only to those who can afford to pay for it. New developments in prenatal screening will have to be assessed in terms of whether and to what extent they either contribute to or undermine the stated aim of providing meaningful options for reproductive choice. In the light of this criterion, this article discusses the introduction of the new non-invasive prenatal test , the tendency to widen the scope of follow-up testing, as well as the possible future scenarios of genome-wide screening and ‘prenatal personalised medicine’. The article ends with recommendations for further debate, research and analysis. (shrink)

Prenatal screening pathways, as nowadays offered in most Western countries consist of similar tests. First, a risk-assessment test for major aneuploides is offered to pregnant women. In case of an increased risk, invasive diagnostic tests, entailing a miscarriage risk, are offered. For decades, only conventional karyotyping was used for final diagnosis. Moreover, several foetal ultrasound scans are offered to detect major congenital anomalies, but the same scans also provide relevant information for optimal support of the pregnancy and the delivery. Recent (...) developments in prenatal screening include the application of microarrays that allow for identifying a much broader range of abnomalities than karyotyping, and non-invasive prenatal testing that enables reducing the number of invasive tests for aneuploidies considerably. In the future, broad NIPT may become possible and affordable. This article will briefly address the ethical issues raised by these technological developments. First, a safe NIPT may lead to routinisation and as such challenge the central issue of informed consent and the aim of prenatal screening: to offer opportunity for autonomous reproductive choice. Widening the scope of prenatal screening also raises the question to what extent ‘reproductive autonomy’ is meant to expand. Finally, if the same test is used for two different aims, namely detection of foetal anomalies and pregnancy-related problems, non-directive counselling can no longer be taken as a standard. Our broad outline of the ethical issues is meant as an introduction into the more detailed ethical discussions about prenatal screening in the other articles of this special issue. (shrink)

The advent of new genetic and genomic technologies may cause friction with the principle of respect for autonomy and demands a rethinking of traditional interpretations of the concept of informed consent. Technologies such as whole‐genome sequencing and micro‐array based analysis enable genome‐wide testing for many heterogeneous abnormalities and predispositions simultaneously. This may challenge the feasibility of providing adequate pre‐test information and achieving autonomous decision‐making. At a symposium held at the 11th World Congress of Bioethics in June 2012 (Rotterdam), organized by (...) the International Association of Bioethics, these challenges were presented for three different areas in which these so‐called ‘new genetics’ technologies are increasingly being applied: newborn screening, prenatal screening strategies and commercial personal genome testing. In this article, we build upon the existing ethical framework for a responsible set‐up of testing and screening offers and reinterpret some of its criteria in the light of the new genetics. As we will argue, the scope of a responsible testing or screening offer should align with the purpose(s) of testing and with the principle of respect for autonomy for all stakeholders involved, including (future) children. Informed consent is a prerequisite but requires a new approach. We present preliminary and general directions for an individualized or differentiated set‐up of the testing offer and for the informed consent process. With this article we wish to contribute to the formation of new ideas on how to tackle the issues of autonomy and informed consent for (public) healthcare and direct‐to‐consumer applications of the new genetics.

It is argued that John Bickle’s Ruthless Reductionism is flawed as an account of the practice of neuroscience. Examples from genetics and linguistics suggest, first, that not every mind-brain link or gene-phenotype link qualifies as a reduction or as a complete explanation, and, second, that the higher (psychological) level of analysis is not likely to disappear as neuroscience progresses. The most plausible picture of the evolving sciences of the mind-brain seems a patchwork of multiple connections and partial explanations, linking anatomy, (...) mechanisms and functions across different domains, levels, and grain sizes. Bickle’s claim that only the molecular level provides genuine explanations, and higher level concepts are just heuristics that will soon be redundant, is thus rejected. In addition, it is argued that Bickle’s recasting of philosophy of science as metascience explicating empirical practices, ignores an essential role for philosophy in reflecting upon criteria for reduction and explanation. Many interesting and complex issues remain to be investigated for the philosophy of science, and in particular the nature of interlevel links found in empirical research requires sophisticated philosophical analysis.

Throughout more than two millennia philosophers adhered massively to ideal standards of scientific rationality going back ultimately to Aristotle’s Analytica posteriora. These standards got progressively shaped by and adapted to new scientific needs and tendencies. Nevertheless, a core of conditions capturing the fundamentals of what a proper science should look like remained remarkably constant all along. Call this cluster of conditions the Classical Model of Science. In this paper we will do two things. First of all, we will propose a (...) general and systematized account of the Classical Model of Science. Secondly, we will offer an analysis of the philosophical significance of this model at different historical junctures by giving an overview of the connections it has had with a number of important topics. The latter include the analytic-synthetic distinction, the axiomatic method, the hierarchical order of sciences and the status of logic as a science. Our claim is that particularly fruitful insights are gained by seeing themes such as these against the background of the Classical Model of Science. In an appendix we deal with the historiographical background of this model by considering the systematizations of Aristotle’s theory of science offered by Heinrich Scholz, and in his footsteps by Evert W. Beth. (shrink)

ABSTRACT In this article, we will first give a historic overview of the concept of benefit sharing and its appearance in official agreements, particularly with respect to crop genetic resources. It will become clear that, at present, benefit sharing is primarily considered as an instrument of compensation or exchange, and thus refers to commutative justice. However, we believe that such a narrow interpretation of benefit sharing disregards, and even undermines, much of its (historical) content and potency, especially where crop genetic (...) resources are concerned. We argue that benefit sharing should not be based merely on commutative justice but rather on a broader model that is also grounded in the concept of distributive justice. This has repercussions for the application of benefit sharing, which we try to clarify by distinguishing between downstream and upstream benefit sharing. Upstream benefit sharing is not so much inspired by compensation for actions done, or the distribution downstream of benefits developed, but by the idea of shared decision‐making on the research and development of resources fundamental to human welfare. Going upstream in the research process of crop genetic resources, and determining research agendas and improving crops according to the needs of the poor, benefit sharing may well be a tool to contribute to world food security and global justice. We concretize our ideas on upstream benefit sharing by introducing a set of criteria that determine the success of consultations on agricultural research agenda setting. (shrink)

It is generally accepted that liberal states should fund public schools for compulsory education. But whether states should also finance denominational schools is controversial. Does such funding not compromise the principle of liberal neutrality? In this article we evaluate two opposing views on this question. Both views give different interpretations of liberal neutrality and both have contrasting views on the relation between education and conceptions of the good. Arguing that neither view is convincing, we defend an alternative view, which holds (...) that the liberal state under certain conditions should fund denominational schools. (shrink)

This study focuses on CEO hubris and its detrimental effect on corporate financial performance along with an examination of critical corporate governance contingencies that may moderate the negative effect. From 654 observations of 164 Korean firms over the years 2001–2008, we found that CEO power exacerbated the negative effect of CEO hubris on corporate financial performance, whereas board vigilance mitigated it. This study provides empirical evidence that entrenchment problems arising from CEO hubris would be exacerbated as CEOs become more powerful, (...) but weakened as board of directors become more vigilant. Theoretical contributions and practical implications will be discussed. (shrink)

This paper concentrates on some aspects of the history of the analyticsynthetic distinction from Kant to Bolzano and Frege. This history evinces considerable continuity but also some important discontinuities. The analytic-synthetic distinction has to be seen in the first place in relation to a science, i.e. an ordered system of cognition. Looking especially to the place and role of logic it will be argued that Kant, Bolzano and Frege each developed the analytic-synthetic distinction within the same conception of scientific rationality, (...) that is, within the Classical Model of Science: scientific knowledge as cognitio exprincipiis. But as we will see, the way the distinction between analytic and synthetic judgments or propositions functions within this model turns out to differ considerably between them. (shrink)

Among the many forms of research misconduct, publishing fraudulent data is considered to be serious where the confidence and validity of the research is detrimentally undermined. In this study, the trend of 303 retracted publications from 44 authors (with more than three retracted publications each) was analysed. The results showed that only 6.60% of the retracted publications were single-authored and the discovery of fraudulent publications had reduced from 52.24 months (those published before the year 2000) to 33.23 months (those published (...) on the year 2000 and onwards). It appears that with the widely accessible public databases like PubMed, fraudulent publications can be detected more easily. The different approaches adopted by authors who had previous publications retracted are also discussed herein. (shrink)

This paper analyses the relationship between Hobbes's theory of language and his theory of science and method. It is shown that Hobbes, at least in his Computatio sive Logica (1655), deviates in some measure from the traditional (Aristotelian) model of language. In this model speech is considered to be a fairly unproblematic expression of thought, which itself is independent of language. Basing himself on a nominalist account of universals, Hobbes states that the demonstration or assertion of universal propositions presupposes speech (...) (more especially, the use of names as marks). This insight turns out to be essential for Hobbes's (rationalist) view of scientific method. (shrink)

Medical missionaries made a breakthrough in Korean history in healing and caring for many Hansen and tuberculosis patients. There was a missionary who had no less good influence than medical missionaries at this time. The person is missionary Sarah Barry, who inspired and developed one of the most influential student movements in South Korea. The aim of the present study is to examine life of Sarah Barry and her ministry, focusing upon her positive influences on Korean intellectuals. The relevance of (...) the study is conditioned by the fact that there is no professional academic research on her ministry except for one short paper, which discusses the importance of her role in formulating campus evangelism. In order to achieve the aim of the study, the method of analysis and synthesis of biographical and historical data was used. As a result of the study, Sarah Barry’s biography was researched and systematized. It gave ground to a conclusion that her role in South Korea’s gradual resurgence after the Civil War was seminal.

SummaryA satisfactory analysis of the well‐known Hangman Paradox is not known to us. Two theses:1. The logical solution of the Hangman Paradox is easy and disappointing.2. The origins of the paradox are manifold and inexhaustible. We analyse particularly perspicuous tuneless version of the paradox due to Hollis .In a sequel which is to appear in Dialectica we analyse two versions of the original Hangman Paradox. Vorbemerkung: Der zweite Autor verdankt Henri Lauener menschlich und philosophisch mehr als dieser Artikel zeigen wird. (...) Es ist mir selten oder nie gelungen, Henri Lauener für eine meiner philosophischen Positionen zu pewinnen, aber ich glaube mich darin mit ihm einig, dass es sich lohnt, Formalismen ernst zu nehmen, um ihre Grenzen zu erkennen.

Evolutionary debunking arguments against religious beliefs move from the claim that religious beliefs are caused by off-track processes to the conclusion that said religious beliefs are unjustified and/or false. Prima facie, EDAs commit the genetic fallacy, unduly conflating the context of discovery and the context of justification. In this paper, we first consider whether EDAs necessarily commit the genetic fallacy, and if not, whether modified EDAs provide successful arguments against theism. Then, we critically evaluate more recent attempts to argue that (...) a more promiscuous evolutionary scepticism renders religious belief unjustified because, unlike commonsense and scientific beliefs, religious beliefs have no way out of such scepticism.

A comparative study of any two things aims to understand one side in terms of the other, find the merits and demerits in each side, and ultimately produce a new thing through a critical synthesis of the two. This comparative study is possible if and only if the two being studied have both similarities and differences. The reason is as follows: if they are completely similar, there is no need for a comparison; if they are completely different, no significant comparison (...) can be made. In a comparative study, accordingly, both differences without similarities and similarities without differences are meaningless. The similarities are the medium that make the meeting (communication) of the two possible and narrow or .. (shrink)

Education has significant and far-reaching effects not only on individuals, but also on the societies in which they live and to which they contribute. The education level of a population affects how a country supports itself and others and the degree to which it can participate in the global field. While everyone from politicians to policymakers to celebrities has stressed the importance of education, there has not been-until now-a vigorous yet comprehensible examination of data to support what has long been (...) common knowledge: education matters. In Education Matters: Global Gains from the 19th to the 21st Century, renowned economists Robert Barro and Jong-Wha Lee present a revolutionary new data set on education in 146 countries since 1870 and projected through 2040. With case studies from the United States, China, and Korea, Barro and Lee evaluate schooling both quantitatively and qualitatively, and assess the role of education in economic and political development. In this comprehensive study, the authors establish the critical role that education plays - particularly for women and girls - in economic growth, fertility, and democracy. The book also addresses sensitive and controversial topics, such as international disparities in education, and the role of education in modernization and development. Both challenging and enlightening, Education Matters has exciting implications for the future of education and promises to be a ground-breaking work in the fields of economics and educational attainment. Engaging and informative, Education Matters is a compelling read for students, scholars, and anyone with a passion for education. (shrink)

The growing emphasis on the importance of publishing scientific findings in the academic world has led to increasing prevalence of potentially significant publications in which scientific and ethical rigour may be questioned. This has not only hindered research progress, but also eroded public trust in all scientific advances. In view of the increasing concern and the complexity of research misconduct, the Committee on Publication Ethics (COPE) was established in 1997 to manage cases with ethical implications. In order to review the (...) outcomes of cases investigated by COPE, a total of 408 cases that had been managed by COPE were successfully extracted and analysed with respect to 7 distinct criteria. The results obtained indicate that the number of ethical implications per case has not changed significantly (p > 0.01) since the year COPE was instigated. Interestingly, the number of ethical cases, and to some extent, research misconduct, is not diminishing. Therefore, journal editors and publishers need to work closely together with COPE to inculcate adoption of appropriate research ethics and values in younger researchers while discouraging others from lowering standards. It is hoped that with a more concerted effort from the academic community and better public awareness, there will be fewer incidences of ethically and scientifically challenged publications. The ultimate aim being to enhance the quality of published works with concomittant public trust in the results. (shrink)

For academic research outcomes, there is an increasing emphasis on the bibliometric scorings like the journal impact factor and citations when the assessment of the scientific merits of research or researchers is required. Currently, no known study has been conducted to explore the bibliographical trends of the subject category of multidisciplinary sciences as indexed by the annual Journal Citation Reports of the Thomson Scientific. The effect of journal self-citations and intra-citing within a discipline to the bibliometric data computation can be (...) confounding. In this study, six journals were selected from the multidisciplinary sciences subject category where the trend of self-citations and intra-citing were analysed. These journals were chosen as they published more than 450 citable articles in the year 2007 and had available bibliometric data for a 10-year period. The results showed that self-citations rose as much as +23.98% while intra-citing declined up to −5.80% over the observed period. The retrospective impacts and influences of these observations were also discussed in this study. (shrink)

There is an increasing trend towards assessing the scientific performance of researchers and institutions of higher learning in the form of journal publications and the associated citations. Currently, the journal impact factor (JIF) value is the most widely used measure for any academic contents. However, there are growing concerns for the unethical practices adopted by journal editors to manipulate the JIF computations. Recently, a Swiss journal, Folia Phoniatrica et Logopaedica which has a JIF value of 0.655 in the year 2006 (...) registers a remarkable JIF increment (of 119%) to 1.439 in the year 2007. It is believed that the journal can achieve such a prominent JIF improvement by publishing a single editorial article that self-cited 66 of its own articles published either in the year 2005 or 2006. The journal has been revoked of any JIF value in the following year of 2008. Thus, it is interesting to review the possible alternative bibliographical trend for the journal should the self-cite event has been avoided, the circumstances leading to the decision by the editor to publish such an article and the possible ethical implications or lessons that can be derived from this incident.

Medical devices have been long used for odiagnostic, therapeutic or rehabilitation purposes. Currently, they can range from a low-cost portable device that is often used for personal health monitoring to high-end sophisticated equipment that can only be operated by trained professionals. Depending on the functional purposes, there are different certification or compliance markings on the device when it is sold. One common certification marking is the Conformité Européenne affixation but this has a range of certification mark numbering for a variety (...) of functional purposes. While the regulators and medical device manufacturers understand the associated significance and clinical implications, these may not be apparent to the professionals and the general public. With portable healthcare devices and mobile applications gaining popularity, better awareness of certification marking will be needed. Particularly, there are differences in the allowed functional purposes and the associated cost derivations of devices with a seemingly similar nature. A preferred approach such as an easy-to-understand notation next to any certification marking on a device can aid in differentiation without the need to digest mountainous regulatory details.

Several studies have focused on the effects of corporate social responsibility fit on external stakeholders’ evaluations of CSR activities, attitudes towards companies or brands, and behaviors. The results so far have been contradictory. A possible reason may be that the concept of CSR fit is more complicated than previously assumed. Researchers suggest that there may be different types of CSR fit, but so far no empirical research has focused on a typology of CSR fit. This study fills this gap, describing (...) a qualitative content analysis of the congruence between six organizations and their various CSR activities. Ten annual reports and CSR reports were analyzed, and 102 specific CSR activities were identified. The results show that two levels of fit must be distinguished: based on the means for and the intended ends of the CSR activity. Furthermore, six different types of fit were found, focusing on products and services, production processes, environmental impact, employees, suppliers, and geographical location. Considering the above variety of fit possibilities, the findings emphasize the role of CSR communication as a means of creating fit perceptions. (shrink)

In the mid-1980s, Dario Donatelli participated in a laboratory study of the effects of around 800 h of practice on digit-span and increased his digit-span from 8 to 104 digits. This study assessed changes in the structure of his memory skill after around 30 years of essentially no practice on the digit-span task. On the first day of testing, his estimated span was only 10 digits, but over the following 3 days of testing it increased to 19 digits. Further analyses (...) of his recall performance and verbal reports identified which mechanisms of the original memory skill he could retrieve or reacquire over the 3 days of practice. We discuss theoretical implications for the retention of skilled memory performance, the effects of age-related changes in memory on it, and for the future study of the effects of disuse on exceptional performance and complex skill.

This study argues that contemporary theology needs a reconceptualised form of metaphysical theology to readdress this question of universality. In order to develop such a new metaphysical theology, de Jong turns to the work of Karl Rahner and Edward Schillebeeckx. Presenting a new perspective on their theological methods, he demonstrates that these theologians employ a dialectical interplay of hermeneutical and metaphysical arguments yielding a modest theological metaphysics. Crucially, these thinkers recognise that acknowledging hermeneutical conditions does not need to end (...) in particularism. Instead, Rahner and Schillebeeckx argue that the infinite variety of particular human experiences can act as potential encounters with the universally self-revealing God. Retrieving these modest forms of theological metaphysics reminds contemporary theology that it is possible to think about universality from within particularity. Balancing the intelligible and mysterious nature of God, Rahner and Schillebeeckx show how a modest theological metaphysics contains its own self-critical hermeneutical disciplining. This renewed understanding about the earlier use of metaphysics opens up new avenues of thought for fundamental theologians that do not want to shy away from the difficult question of the universality of God.

In light of the advancements in cognitive science and the evolutionary psychology of religion in the past two decades, scientists and philosophers have begun to reflect on the theological and atheological implications of naturalistic—and in particular, evolutionary—explanations of religious belief and behaviour. However, philosophical naiveté is often evinced by scientists and scientific naiveté by philosophers. The aim of this article is to draw from these recent contributions, point out some common pitfalls and important insights, and suggest a way forward. This (...) proposal avoids the genetic fallacy as well as misunderstandings of the cognitive mechanisms that give rise to religious belief. In the end, it may well be that the cognitive science of religion is atheologically and theologically ambiguous; traditional philosophers of religion on both sides of the debate still have work to do.

Most mathematical models used to examine the role of different stages of human immunodeficiency virus infection unrealistically assume that HIV is transmitted through one-off contacts or that transmission rates are the same between males and females. We sought to examine whether inferences from previous models are robust to the relaxation of those unrealistic assumptions. We developed a model of HIV transmissions through sexual partnerships assuming that sexual partnerships have variable duration, sexual partnerships are concurrent, and the male-to-female transmission rate is (...) higher than the female-to-male transmission rate, with a focus on the third assumption. Assuming a higher rate for male-to-female than female-to-male transmissions decreases the overall transmission of HIV but increases the equilibrium fraction of transmissions during primary HIV infection in long-term partnerships, compared to the case where transmission rates are assumed to be symmetric between males an females. Previous modeling studies that assume symmetric transmission rates between males and females may have overestimated the overall spread of HIV, but underestimated the relative contribution of PHI. To make robust inferences on the role of different stages of HIV infection in the sexual spread of HIV, models should take into account that transmission rates may be asymmetric by sex. (shrink)

In this study I attempt to provide an answer to the question how the Babylonian scholars arrived at their mathematical theory of planetary motion. Although no texts are preserved in which the Babylonians tell us how they did it, from the surviving Astronomical Diaries we have a fairly complete picture of the nature of the observational material on which the scholars must have based their theory and from which they must have derived the values of the defining parameters. Limiting the (...) discussion to system A theory of the outer planets Saturn, Jupiter and Mars, I will argue that the development of Babylonian planetary theory was a gradual process of more than a century, starting sometime in the fifth century BC and finally resulting in the appearance of the first full-fledged astronomical ephemeris around 300 BC. The process of theory formation involved the derivation of long “exact” periods by linear combination of “Goal–Year” periods, the invention of a 360° zodiac, the discovery of the variable motion of the planets and the development of the numerical method to model this as a step function. Longitudes of the planets in the Babylonian zodiac could be determined by the scholars with an accuracy of 1° to 2° from observations of angular distances to Normal Stars with known positions. However, since the sky is too bright at first and last appearances of the planets and at acronychal rising for nearby stars to be visible, accurate longitudes as input for theoretical work could only be determined when the planets were near the stationary points in their orbits. In this study I show that the Babylonian scholars indeed based their system A modeling of the outer planets on planetary longitudes near stations, that their system A models of Saturn and Jupiter provided satisfactory results for all synodic phenomena, that they realized that their system A model of Mars did not produce satisfactory results for the second station so that separate numerical schemes were constructed to predict the positions of Mars at second station from the model at first station, and finally that their system A model for Mars provided quite poor predictions of the longitude of Mars at first and last appearances over large stretches of the zodiac. I further discuss ways in which the parameters of the system A models may have been derived from observations of the outer planets. By analyzing contemporaneous ephemerides from Uruk of four synodic phenomena of Jupiter from the second century BC, I finally illustrate how the Babylonian scholars may have used observations of Normal Star passages of planets to choose the initial conditions for their ephemerides.
