Citing of previous publications is an important factor in knowledge development. Because of the great amount of publications available, only a selection of studies gets cited, for varying reasons. If the selection of citations is associated with study outcome this is called citation bias. We will study determinants of citation in a broader sense, including e.g. study design, journal impact factor or the funding source of the publication. As a case study we assess which factors drive citation in the human (...) literature on phthalates, specifically the metabolite mono phthalate. A systematic literature search identified all relevant publications on human health effect of MEHP. Data on potential determinants of citation were extracted in duplo. Specialized software was used to create a citation network, including all potential citation pathways. Random effect logistic regression was used to assess whether these determinants influence the likelihood of citation. 112 Publications on MEHP were identified, with 5684 potential citation pathways of which 551 were actual citations. Reporting of a harmful point estimate, journal impact factor, authority of the author, a male corresponding author, research performed in North America and self-citation were positively associated with the likelihood of being cited. In the literature on MEHP, citation is mostly driven by a number of factors that are not related to study outcome. Although the identified determinants do not necessarily give strong indications of bias, it shows selective use of published literature for a variety of reasons. (shrink)

BackgroundKnowledge development depends on an unbiased representation of the available evidence. Selective citation may distort this representation. Recently, some controversy emerged regarding the possible impact of swimming on childhood asthma, raising the question about the role of selective citation in this field. Our objective was to assess the occurrence and determinants of selective citation in scientific publications on the relationship between swimming in chlorinated pools and childhood asthma.MethodsWe identified scientific journal articles on this relationship via a systematic literature search. The (...) following factors were taken into account: study outcome (authors’ conclusion, data-based conclusion), other content-related article characteristics (article type, sample size, research quality, specificity), content-unrelated article characteristics (language, publication title, funding source, number of authors, number of affiliations, number of references, journal impact factor), author characteristics (gender, country, affiliation), and citation characteristics (time to citation, authority, self-citation). To assess the impact of these factors on citation, we performed a series of univariate and adjusted random-effects logistic regressions, with potential citation path as unit of analysis.ResultsThirty-six articles were identified in this network, consisting of 570 potential citation paths of which 191 (34%) were realized. There was strong evidence that articles with at least one author in common, cited each other more often than articles that had no common authors (odds ratio (OR) 5.2, 95% confidence interval (CI) 3.1–8.8). Similarly, the chance of being cited was higher for articles that were empirical rather than narrative (OR 4.2, CI 2.6–6.7), that reported a large sample size (OR 5.8, CI 2.9–11.6), and that were written by authors with a high authority within the network (OR 4.1, CI 2.1–8.0). Further, there was some evidence for citation bias: articles that confirmed the relation between swimming and asthma were cited more often (OR 1.8, CI 1.1–2.9), but this finding was not robust.ConclusionsThere is clear evidence of selective citation in this research field, but the evidence for citation bias is not very strong.

IntroductionBisphenol A is highly debated and studied in relation to a variety of health outcomes. This large variation in the literature makes BPA a topic that is prone to selective use of literature, in order to underpin one’s own findings and opinion. Over time, selective use of literature, by means of citations, can lead to a skewed knowledge development and a biased scientific consensus. In this study, we assess which factors drive citation and whether this results in the overrepresentation of (...) harmful health effects of BPA.MethodsA citation network analysis was performed to test various determinants of citation. A systematic search identified all relevant publications on the human health effect of BPA. Data were extracted on potential determinants of selective citation, such as study outcome, study design, sample size, journal impact factor, authority of the author, self-citation, and funding source. We applied random effect logistic regression to assess whether these determinants influence the likelihood of citation.ResultsOne hundred sixty-nine publications on BPA were identified, with 12,432 potential citation pathways of which 808 citations occurred. The network consisted of 63 cross-sectional studies, 34 cohort studies, 29 case-control studies, 35 narrative reviews, and 8 systematic reviews. Positive studies have a 1.5 times greater chance of being cited compared to negative studies. Additionally, the authority of the author and self-citation are consistently found to be positively associated with the likelihood of being cited. Overall, the network seems to be highly influenced by two highly cited publications, whereas 60 out of 169 publications received no citations.ConclusionIn the literature on BPA, citation is mostly driven by positive study outcome and author-related factors, such as high authority within the network. Interpreting the impact of these factors and the big influence of a few highly cited publications, it can be questioned to which extent the knowledge development in human literature on BPA is actually evidence-based.

This study explores the relationship between moral intensity and the use of different sensemaking strategies in military critical incidents. First, narratives of military personnel were used to select prototypical high/low moral intensity critical incidents. In a follow-up, a scenario study was conducted with active duty military personnel to examine the relationship between moral intensity and the use of sensemaking tactics. This study offers three main conclusions. First, the use of sensemaking tactics is strongly tied to the level of moral intensity (...) in the situation. In high-intense situations, the servicemen draw on previous experiences, prediction of consequences, and help of others to recognize and interpret the situation. Less attention goes out to higher level critical thinking. Thus, it seems that in these critical incidents, the servicemen react without giving room for thorough consideration and deliberation. Second, the number of deployments a serviceman experienced influences the perceived seriousness and harmfulness of the situation negatively in low-intense situations. Finally, and in line with earlier studies, the results indicate that the concept of moral intensity is formed out of three rather than the six dimensions originally proposed by Jones. The implications of these findings are discussed. (shrink)

The present study examined whether a dissociation among formats for rational numbers can be obtained in tasks that require comparing a number to a non-symbolic quantity. In Experiment 1, college students saw a discrete or else continuous image followed by a rational number, and had to decide which was numerically larger. In Experiment 2, participants saw the same displays but had to make a judgment about the type of ratio represented by the number. The magnitude task was performed more quickly (...) using decimals, whereas the relation task was performed more accurately with fractions. The pattern observed for percentages was very similar to that for decimals. A dissociation between magnitude comparison and relational processing with rational numbers can be obtained when a symbolic number must be compared to a non-symbolic display. (shrink)

In our recent article, "Where Does Cumulative Culture Begin? A Plea for a Sociologically Informed Perspective" we commented on a fundamental notion in current approaches to cultural evolution, the “zones of latent solutions”, and proposed a modification of it, namely a social and dynamic interpretation of the latent solutions which were originally introduced within an individualistic framework and as static, genetically fixed entities. This modification seemed, and still seems, relevant to us and, in particular, more adequate for coping with the (...) archaeological record. Bandini et al. rejected our proposition and deemed it unnecessary. In their critique, they focused on: our reservations about an individualistic approach; our objections to the presumption of fully naive individuals; and our demand for an extended consideration of forms of social learning simpler than emulation and imitation. We will briefly reply to their critique in order to clarify some misunderstandings. However, the criticisms also show that we are at an impasse on certain crucial topics, such as the meaning of ZLS and the scope and nature of culture in general. Thus, we consider it necessary to make an additional effort to identify the conceptual roots which are at the very basis of the dissent with Bandini et al. (shrink)

At the beginning of the twentieth century, among the foundational schools of mathematics appeared ‘intuitionism’ by Dutchman L. E. J. Brouwer, who based arithmetic on the intuition of time and all mental constructions that could be made out of it. His pupil Arend Heyting was the first populariser of intuitionism, and he repeatedly emphasised that no philosophy was required to practise intuitionism so that such mathematics could be shared by anyone. Still, stimulated by invitations to humanistic conferences, he wrote a (...) series of notes, preserved in the State Archives, Haarlem, about solipsism. In them, he operated a series of theoretical reflections consisting of the stripping away of the patterns that are part of our consciousness and their subsequent progressive re-introduction, in order to understand the formation of our Self as distinct from the natural world and other humans. In 1996, following a stroke, neuroscientist Jill Bolte Taylor experienced the deprivation of certain abilities in her brain and their successive regaining. In her experience there are remarkable similarities with what Heyting had hypothesised about the formation of the self. The purpose of this article is to highlight them and point out how Heyting's theoretical construct was found to be embodied in the brain. (shrink)

This paper presents the content of the unpublished notes that the Dutch mathematician Arend Heyting wrote in different periods of his life on solipsism and that are preserved in Heyting's archive at the University of Amsterdam. Most of the notes are quoted here and translated into English. Their study shows the originality of Heyting's reflections on a subject that was typical of his master, L. E. J. Brouwer, the father of intuitionism.

Cette enquête est motivée par la coexistence dans l’Antiquité tardive de trois mots exprimant d’une façon différente la lecture : ἀνάγνωσις, qui signifie « lire à haute voix » ; συνανάγνωσις, c’est-à-dire « lire avec quelqu’un » ; ἔντευξις, qui, parmi différentes significations, présente celle de « lecture » au sens général. À partir du V e siècle ap. J.-C., leur emploi est strictement lié à deux phénomènes importants : le premier est l’introduction des mots ἀνάγνωσις et συνανάγνωσις dans la (...) pratique d’enseignement de l’école néoplatonicienne comme synonymes indiquant une lecture exégétique des œuvres anciennes par le maître ; le deuxième concerne la diffusion de la formule « ceux qui lisent » (ἐντυγχάνοντες) ou « ceux qui vont lire » (ἐντευξόμενοι) dans les avertissements au lecteur des premiers commentaires composés directement sous forme écrite dans l’Antiquité tardive. Cette étude vise à démontrer que dans le milieu de l’école néoplatonicienne le couple ἐντυγχάνοντες / ἐντευξόμενοι est en rapport de conséquence avec le couple ἀνάγνωσις / συνανάγνωσις, exprimant un point de vue différent sur le destinataire : en effet, l’ἀνάγνωσις / συνανάγνωσις, en tant que pratique orale, est immédiatement reçue par l’élève, qui possède les aptitudes et les compétences appropriées pour comprendre ; le commentaire, en revanche, en tant que transposition de l’enseignement à l’écrit, doit faire face à deux difficultés : l’explicitation ponctuelle du sens caché dans les textes anciens que les lecteurs ont déjà sous les yeux (ἐντυγχάνοντες) ; et la persuasion d’un public de lecteurs (ἐντευξόμενοι), qui liront le commentaire.

INDIVIDUALITY has given philosophers considerable trouble. There are conflicting views as to how to understand it and even as to its intelligibility in spite of what appears to be its fundamental character in our experience. For, on the one hand, we seem to experience the world in terms of individuals, but when we try to explain what their individuality is we run into difficulties. Indeed, even a view which at first sight appears quite innocuous, defining individuality formally as a feature (...) which characterizes individuals as individuals, is strongly rejected by many. They argue that individuality cannot be a feature at all in the strict sense of the word, since its being a feature would presuppose that something else could share on it or have it, and that seems to contradict the very notion of individuality. At any rate, this is of no concern to us presently since it is an issue which pertains to the ontological status of individuality rather than its intension. It suffices to point out for the moment that there is ample disagreement concerning the proper understanding of individuality. (shrink)

Employment and Employee Rights addresses the issue of rights in the workplace. Although much of the literature in this field focuses on employee rights, this volume considers the issue from the perspective of both employees and employers. Considers the rights of both employees and employers. Discusses the moral and legal landscape and traditional assumptions about right in employment. Investigates arguments for guaranteeing rights, particularly for employees, which are derived from relational, developmental, and economic bases. Explores new dimensions of employment including (...) a model that incorporates growing workplace diversity, builds upon our understanding of the legal landscape, and expands upon our justifications for recognizing and protecting rights.

Institutional ethics committees (IECs) are part of a growing phenomenon in the American health care system. Although a major force driving hospitals to establish IECs is the desire to resolve difficult clinical dilemmas in a quick and systematic way, in this paper we argue that such a goal is naive and, to some extent, misguided. We assess the growing trend of these committees, analyse the theoretical assumptions underlying their establishment, and evaluate their strengths and shortcomings. We show how the 'medical (...) consultation' model is often inappropriately applied to IECs and suggest that IECs must operate under a different framework. Finally, we argue that IECs should be valued for the process they facilitate, and not for the product that they are, often unreasonably, expected to deliver. (shrink)

The question “What is philosophy?” is difficult to answer because it seems to presuppose answers to long‐standing and controversial philosophical questions. As answers to these questions affect one’s metaphilosophy, apparently irresolvable philosophical disagreements are then converted into deadlock concerning the nature of the discipline. As this problem is unique to philosophy, however, this difficulty itself reveals something of philosophy’s essential nature. As, under analysis, it turns out to arise from a definite way of posing problems, philosophy can initially be defined (...) by a particular mode of problematisation. This essay establishes this argument and proposes a method for developing this insight into a fully realised, socio‐historical metaphilosophy. This involves stages of (a) hermeneutical analysis and (b) historical contextualisation, both of which increase the account’s empirical adequacy. A conclusion discusses the extent to which philosophy is on trial here and argues that questioning the future of philosophy is not inherently philistine. (shrink)

Potential ethical issues can arise during the process of epidemiological classification. For example, unnatural infant deaths are classified as accidental deaths or homicides. Societal sensitivity to the physical abuse and neglect of children has increased over recent decades. This enhanced sensitivity could impact reported infant homicide rates. Infant homicide and accident mortality rates in boys and girls in the USA from 1940 to 2005 were analysed. In 1940, infant accident mortality rates were over 20 times greater than infant homicide rates (...) in both boys and girls. After about 1980, when the ratio of infant accident mortality rates to infant homicide rates decreased to less than five, and the sum of infant accident and homicide rates became relatively constant, further decreases in infant accident mortality rates were associated with increases in reported infant homicide rates. These findings suggest that the dramatic decline of accidental infant mortality and recent increased societal sensitivity to child abuse may be related to the increased infant homicide rates observed in the USA since 1980 rather than an actual increase in societal violence directed against infants. Ethical consequences of epidemiological classification, involving the principles of beneficence, non-maleficence and justice, are suggested by observed patterns in infant accidental deaths and homicides in the USA from 1940 to 2005.

In The Second Sex, Simone de Beauvoir revealed that it is just this freedom of withdrawal from self that woman cannot gain because of the constant effort of establishing and guarding her identity against an enforced background of passivity, ornamentality and self-enclosure. Even as a small child, woman is taught how to.

Descriptions of battles in ancient authors are not mirrors of reality, however dim and badly cracked, but are a form of literary production in which the real events depicted are filtered through the literary, intellectual, and cultural assumptions of the author. By comparing the battle descriptions of Julius Caesar to those of Xenophon and Polybius this paper attempts to place those battle descriptions in their intellectual and cultural context. Here Caesar appears as a military intellectual engaged in controversies with experts (...) in the Greek tradition of military theory-rejecting materialist strains of Greek thinking-and also as a Roman soldier whose military experience and cultural conceptions about how battles work could not be fully accommodated by Greek models. Caesar adapts from the Greeks an intellectual model of tactics based on physical metaphors, but adjusts Greek theory to Roman experience: Caesar's tactical physics ramifies from the crash-impetus-of the legionary charge rather than the push of the phalanx. Caesar also adapts from the Greeks a simplifying model of military psychology, adjusting a Greek binary scheme of morale into a three-level model to accommodate a Roman military ethos of steadiness in combat. Greek military thinking downplayed the role in battle of innate differences in courage between armies or nations, concentrating instead on tactics and stratagems; Roman culture encouraged Caesar to reject this dismissive view and elaborate a detailed understanding of the role of courage-virtus-in the mechanics of battle. The prominence of virtus in Caesar's battle descriptions illustrates its survival as an important Roman cultural norm and tempts speculation as to its historical consequences. Attempts to reconstruct ancient battles must take into account the cultural and intellectual traditions which guide ancient battle descriptions. (shrink)

Assume that we communicate for the purpose of trying to change a person's behavior either overtly or covertly. As long as this is done in an honest manner, no concern with ethics is involved. But suppose a communication pattern — subliminals — is developed that covertly tries to change our behavior without our consent. Then, concern with ethics is involved.Very little evidence exists to support a definitive quantitative impact of subliminal communication. There is a suggestion, however, that subliminals do in (...) fact manipulate people to do certain things. If this is so, then we have an over-riding issue in ethics — the ultimate invasion of a person's privacy — his mind. (shrink)

THE AUDIENCE IS THE REAL or imaginary group of persons who are in fact acquainted, could be acquainted, or are meant to be acquainted with a given text. Etymologically, the term "audience" refers to a group of listeners. This meaning of the term goes back to a time when the primary form of acquaintance with the work of an author was through the spoken word. From the invention of the printing press, however, until the time when the use of the (...) radio became widespread, written texts were the primary way of learning about an author's work. Although contemporary media have changed this to a certain extent, in science and the humanities it is still true that the audience for an author's work consists largely of readers. For my present purposes, the distinction between readers and listeners is immaterial and, hence, I often refer to an audience as a group of readers, although what I say about it will apply, mutatis mutandis, to listeners as well.
