Objective To assess whether the frequency of end-of-life decisions for children under 1 year of age in the Netherlands has changed since ultrasound examination around 20 weeks of gestation became routine in 2007 and after a legal provision for deliberately ending the life of a newborn was set up that same year. Methodology This was a recurrent nationwide cross-sectional study in the Netherlands. In 2010, a sample of death certificates from children under 1 year of age was derived from the (...) central death registry. All 223 deaths that occurred in a 4-month study period were included. Physicians who had reported a non-sudden death (n=206) were sent a questionnaire on the end-of-life decisions made. 160 questionnaires were returned (response 78%). Findings In 2010, 63% of all deaths of children under 1 year of age were preceded by an end-of-life decision—a percentage comparable to other times when this study was conducted (1995, 2001, 2005). These end-of-life decisions were mainly decisions to withdraw or withhold potentially life-sustaining treatment. In 2010, the percentage of cases in which drugs were administered with the explicit intention to hasten death was 1%, while in 1995 and 2001, this was 9% and in 2005, this was 8%. Discussion and conclusion There has been a reduction of infant deaths that followed administration of drugs with the explicit intention to hasten death. One explanation for this reduction relates to the introduction of routine ultrasound examination around 20 weeks of gestation. In addition, the introduction of legal criteria and a review process for deliberately ending the life of a newborn may have left Dutch physicians with less room to hasten death. (shrink)

Several extensions of the basic modal language are characterized in terms of interpolation. Our main results are of the following form: Language ℒ' is the least expressive extension of ℒ with interpolation. For instance, let ℳ be the extension of the basic modal language with a difference operator [7]. First-order logic is the least expressive extension of ℳ with interpolation. These characterizations are subsequently used to derive new results about hybrid logic, relation algebra and the guarded fragment.

Teachers´ attitudes toward their students have been associated with differential teachers´ expectations and, in turn, with students´ educational pathways. Theories of social cognition can explain the link between attitudes and behavior. In this regard, the distinction between implicit and explicit attitudes is worth to be considered, whereby implicit attitudes are automatically activated when the attitude object is present and guide automatic behavior. In contrast, explicit attitudes infer deliberation and reflection, hence affecting controlled behavior. As teachers often are required to act (...) immediately in situations that do not allow for thoughtful reflection due to time restraints, teachers´ implicit attitudes concerning different student groups with shared characteristics, such as gender or ethnicity, may be especially important when considering teachers´ behavior in relation to students´ educational pathways. This notion is reflected by an increased interest in adopting implicit methodology in the educational domain. Over the last 10 years, several studies have been conducted in different countries, involving in- and preservice teachers and investigating their attitudes toward different student groups. Estimates of effects have varied and may be affected by sampling bias. To systematically review and integrate data from different studies, this meta-analysis focuses on teachers´ implicit attitudes. Following the systematic search of the database and initial screening, 43 articles were identified from which 22, describing 34 studies, were retained for the meta-analysis after further inspection. First analyses revealed an estimated average effect size of 0.56 for implicit attitudes in favor of non-marginalized groups. As there was a large extent of heterogeneity between studies, several moderator variables, were investigated. Results showed that the employed implicit measure and stimulus materials as well as the student target group affected the effect sizes. Low or non-significant relationships were reported between implicit and explicit attitudes. Findings are discussed in terms of theory and future research. (shrink)

In this paper we study the expressive power and definability for modal languages interpreted on topological spaces. We provide topological analogues of the van Benthem characterization theorem and the Goldblatt–Thomason definability theorem in terms of the well-established first-order topological language.

We consider second-order propositional modal logic (SOPML), an extension of the basic modal language with propositional quantifiers introduced by Kit Fine in 1970. We determine the precise expressive power of SOPML by giving analogues of the Van Benthem–Rosen theorem and the Goldblatt Thomason theorem. Furthermore, we show that the basic modal language is the bisimulation invariant fragment of SOPML, and we characterize the bounded fragment of first-order logic as being the intersection of first-order logic and SOPML.

In this paper we argue that hybrid logic is the deductive setting most natural for Kripke semantics. We do so by investigating hybrid axiomatics for a variety of systems, ranging from the basic hybrid language (a decidable system with the same complexity as orthodox propositional modal logic) to the strong Priorean language (which offers full first-order expressivity).We show that hybrid logic offers a genuinely first-order perspective on Kripke semantics: it is possible to define base logics which extend automatically to a (...) wide variety of frame classes and to prove completeness using the Henkin method. In the weaker languages, this requires the use of non-orthodox rules. We discuss these rules in detail and prove non-eliminability and eliminability results. We also show how another type of rule, which reflects the structure of the strong Priorean language, can be employed to give an even wider coverage of frame classes. We show that this deductive apparatus gets progressively simpler as we work our way up the expressivity hierarchy, and conclude the paper by showing that the approach transfers to first-order hybrid logic.

Artificial grammar learning (AGL) is used to study how human adults, infants, animals or machines learn various sorts of rules defined over sounds or visual items. Ten Cate et al. introduce the topic and provide a critical synthesis of this important interdisciplinary area of research. They identify the questions that remain open and the challenges that lie ahead, and argue that the limits of human, animal and machine learning abilities have yet to be found.

Human language is a salient example of a neurocognitive system that is specialized to process complex dependencies between sensory events distributed in time, yet how this system evolved and specialized remains unclear. Artificial Grammar Learning (AGL) studies have generated a wealth of insights into how human adults and infants process different types of sequencing dependencies of varying complexity. The AGL paradigm has also been adopted to examine the sequence processing abilities of nonhuman animals. We critically evaluate this growing literature in (...) species ranging from mammals (primates and rats) to birds (pigeons, songbirds, and parrots) considering also cross‐species comparisons. The findings are contrasted with seminal studies in human infants that motivated the work in nonhuman animals. This synopsis identifies advances in knowledge and where uncertainty remains regarding the various strategies that nonhuman animals can adopt for processing sequencing dependencies. The paucity of evidence in the few species studied to date and the need for follow‐up experiments indicate that we do not yet understand the limits of animal sequence processing capacities and thereby the evolutionary pattern. This vibrant, yet still budding, field of research carries substantial promise for advancing knowledge on animal abilities, cognitive substrates, and language evolution. (shrink)

This paper provides several examples of how modal logic can be used in studying the XML document navigation language XPath. More specifically, we derive complete axiomatizations, computational complexity and expressive power results for XPath fragments from known results for corresponding logics. A secondary aim of the paper is to introduce XPath in a way that makes it accessible to an audience of modal logicians.

Dynamic predicate logic (DPL), presented in [5] as a formalism for representing anaphoric linking in natural language, can be viewed as a fragment of a well known formalism for reasoning about imperative programming [6]. An interesting difference from other forms of dynamic logic is that the distinction between formulas and programs gets dropped: DPL formulas can be viewed as programs. In this paper we show that DPL is in fact the basis of a hierarchy of formulas-as-programs languages.

The implementation of inclusive policies is largely dependent on teachers´ willingness to accommodate students with special educational needs (SEN) in mainstream classrooms, which is affected by their perceived competence and attitudes. This study investigated attitudes of pre- and in-service teachers toward students with two types of SEN: challenging behavior and learning difficulties. The three components of attitude (affective, cognitive, and behavioral) were assessed using indirect and direct measures. Results revealed that teachers held negative implicit attitudes toward challenging behavior and learning (...) difficulties, however implicit attitudes did not vary as a function of the type of SEN. Ratings of the stereotypical dimensions warmth and competence and overall ratings of scholastic achievement were affected by professional status and type of SEN. Professional status, implicit attitudes and stereotypical knowledge together explained 52 and 43% of the variance in teachers´ ratings of academic proficiency for students with challenging behavior and learning difficulties, respectively. Results are interpreted within the theoretical framework and implications for teacher training are discussed. (shrink)

Background Genuine uncertainty on superiority of one intervention over the other is called equipoise. Physician-investigators in randomized controlled trials need equipoise at least in studies with more than minimal risks. Ideally, this equipoise is also present in patient-participants. In pediatrics, data on equipoise are lacking. We hypothesize that 1) lack of equipoise at enrolment among parents may reduce recruitment; 2) lack of equipoise during participation may reduce retention in patients assigned to a less favoured treatment-strategy. Methods We compared preferences of (...) parents/patients at enrolment, documented by a questionnaire, with preferences developed during follow-up by an interview-study to investigate equipoise of child-participants and parents in the BeSt-for-Kids-study. This trial in new-onset Juvenile Idiopathic Arthritis-patients consists of three strategies. One strategy comprises initial treatment with a biological disease-modifying-antirheumatic-drug, currently not standard-of-care. Semi-structured interviews were conducted with 23 parents and 7 patients, median 11 months after enrolment. Results Initially most parents and children were not in equipoise. Parents/patients who refused participation, regularly declined due to specific preferences. Many participating families preferred the biological-first-strategy. They participated to have a chance for this initial treatment, and would even consider stopping trial-participation when not randomized for it. Their conviction of superiority of the biological-first strategy was based on knowledge from internet and close relations. According to four parents, the physician-investigator preferred the biological-first-strategy, but the majority stated that she had no preferred strategy. In phase 2, preferences tended to change to the treatment actually received. Conclusions Lack of equipoise during enrolment did not reduce study recruitment, mainly due to the fact that preferred treatment was only available within the study. Still, when developing a trial it is important to evaluate whether the physicians’ research question is in line with preferences of the patient-group. By exploring so-called ‘informed patient-group’-equipoise, successful recruitment may be enhanced and bias avoided. In our study, lack of equipoise during trial-participation did not reduce retention in those assigned to a less favoured option. We observed a change for preference towards treatment actually received, possibly explained by comparable outcomes in all three arms. (shrink)

The human blood coagulation system comprises a series of linked glycoproteins that upon activation induce the generation of downstream enzymes ultimately forming fibrin. This process is primarily important to arrest bleeding (hemostasis). Hemostasis is a typical example of a molecular machine, where the assembly of substrates, enzymes, protein cofactors and calcium ions on a phospholipid surface markedly accelerates the rate of coagulation. Excess, pathological, coagulation activity occurs in “thrombosis”, the formation of an intravascular clot, which in the most dramatic form (...) precipitates in the microvasculature as disseminated intravascular coagulation. Thrombosis occurs according to a biochemical machine model in the case of atherothrombosis on a ruptured atherosclerotic plaque, but may develop at a slower rate in venous thrombosis, illustrating that the coagulation machinery can act at different velocities. The separate coagulation enzymes are also important in other biological processes, including inflammation for which the rapid conversion of one coagulation factor by the other is not a prerequisite. The latter role of coagulation enzymes may be related to the old and probably maintained function of the coagulation machine in innate immunity.

Mueller et al. discuss the role of acoustic cues in detecting language structure more generally. Across languages, there are clear links between acoustic cues and syntactic structure. They show that AGL experiments implementing analogous links demonstrate that prosodic cues, as well as various auditory biases, facilitate the learning of structural rules. Some of these biases, e.g. for auditory grouping, are also present in other species.

The Guarded Negation Fragment (GNFO) is a fragment of first-order logic that contains all positive existential formulas, can express the first-order translations of basic modal logic and of many description logics, along with many sentences that arise in databases. It has been shown that the syntax of GNFO is restrictive enough so that computational problems such as validity and satisfiability are still decidable. This suggests that, in spite of its expressive power, GNFO formulas are amenable to novel optimizations. In this (...) article we study the model theory of GNFO formulas. Our results include effective preservation theorems for GNFO, effective Craig Interpolation and Beth Definability results, and the ability to express the certain answers of queries with respect to a large class of GNFO sentences within very restricted logics.

Scholars have long been captivated by the parallels between birdsong and human speech and language. In this book, leading scholars draw on the latest research to explore what birdsong can tell us about the biology of human speech and language and the consequences for evolutionary biology. They examine the cognitive and neural similarities between birdsong learning and speech and language acquisition, considering vocal imitation, auditory learning, an early vocalization phase, the structural properties of birdsong and human language, and the striking (...) similarities between the neural organization of learning and vocal production in birdsong and human speech. After outlining the basic issues involved in the study of both language and evolution, the contributors compare birdsong and language in terms of acquisition, recursion, and core structural properties, and then examine the neurobiology of song and speech, genomic factors, and the emergence and evolution of language.

Enszer “She Who Shouts Gets Heard!”: Counting and Accounting for Women Writers in Literary Grants and Norton Anthologies In 1979, the Coordinating Council of Literary Magazines (CCLM), a New York-based nonprofit that supported literary magazines through technical assistance and grant-making, announced a new program: CCLM editor fellowships.1 Editor fellowships came with a $5,000 grant. Members (...) of the literary community nominated editors to CCLM for the award. Adrienne Rich nominated Ellen Marie Bissert, editor of the feminist journal 13th Moon, and Mab Segrest, editor of Feminary: A Feminist Journal for the South Emphasizing the Lesbian Vision, for the editor fellowships. In 1979, the inaugural year of the prize, among the ten winners, not one was a woman. Bissert was one of three honorable mentions. Bissert rejected the distinction with a public letter to Maureen Owen, the only woman on the CCLM board of directors. Bissert deplored “the sexism inherent in the panelists’ decisions.”2 Several feminist publications reprinted Bissert’s letter while “the male small press gave it scant 1.

Of the 124 people who completed the applications, twenty-three (19%) were women and eleven (9%) were nonwhite men. There were thirty-three semifinalists, five (15%) women and four (12%) non-white men. These numbers shocked and outraged Bissert and other feminists. Adrienne Rich wrote to Maureen Owen, “I am appalled by the blatant sexism evidenced in the Council’s decision to fund ten male editors.”4 The attention that Bissert brought to the grant process resulted in a special meeting of the CCLM board to “discuss the controversy” and the awards.5 The next year, the CCLM editor fellowships went to five journals run by women and five run by men; one of the winners of the $5,000 award in 1980 was the editorial collective of Conditions, a magazine of writing by women with an emphasis on writing by lesbians.6 In a letter to readers of Conditions, the three editors, Elly Bulkin, Jan Clausen, and Rima Shore, noted that the “feminist protest following the announcement of the 1979 awards no doubt had an impact on the decision-making process” and that the award “represents the only substantial payment we have received, or seem likely to receive, for our editorial work, and we were greatly encouraged by it.”7 Maureen Owen acknowledged the importance of Bissert’s protests saying it “strengthened my position on the board at CCLM and the position of women editors and writers in general. She who shouts, get heard!”8 In 1979, Bissert, Rich, and other feminists demonstrated the importance of shouting about the inclusion of women in systems of literary appraisal; they recognized the important economic consequences of grants for feminist publishers and feminist authors.

AbstractBackgroundEthical challenges constitute an inseparable part of daily decision-making processes in all areas of healthcare. In prehospital emergency medicine, decision-making commonly takes place in everyday life, under time pressure, with limited information about a patient and with few possibilities of consultation with colleagues. This paper explores the ethical challenges experienced by prehospital emergency personnel. MethodsThe study was grounded in the tradition of action research related to interventions in health care. Ethical challenges were explored in three focus groups, each attended by (...) emergency medical technicians, paramedics, and prehospital anaesthesiologists. The participants, 15 in total, were recruited through an internal information network of the emergency services. Focus groups were audio-recorded and transcribed verbatim.ResultsThe participants described ethical challenges arising when clinical guidelines, legal requirements, and clinicians’ professional and personal value systems conflicted and complicated decision-making processes. The challenges centred around treatment at the end of life, intoxicated and non-compliant patients, children as patients—and their guardians, and the collaboration with relatives in various capacities. Other challenges concerned guarding the safety of oneself, colleagues and bystanders, prioritising scarce resources, and staying loyal to colleagues with different value systems. Finally, challenges arose when summoned to situations where other professionals had failed to make a decision or take action when attending to patients whose legitimate needs were not met by the appropriate medical or social services, and when working alongside representatives of authorities with different roles, responsibilities and tasks.ConclusionFrom the perspective of the prehospital emergency personnel, ethical challenges arise in three interrelated contexts: when caring for patients, in the prehospital emergency unit, and during external collaboration. Value conflicts may be identified within these contexts as well as across them. A proposed model of analysis integrating the above contexts can assist in shedding light on ethical challenges and value conflicts in other health care settings. The model emphasises that ethical challenges are experienced from a particular professional perspective, in the context of the task at hand, and in a particular, the organisational setting that includes work schedules, medical guidelines, legal requirements, as well as professional and personal value systems.

The point of departure in this article is the Danish debate about democracyin schools. This article presents a first step in a study of how the relationshipbetween democracy and education can be understood. A juxtaposition of thetwo concepts requires, first of all, an analysis of how the concept of democracyis used in the educational debate. In this article three models of democracy areapplied as an analytical framework: a liberal model (Hobbes, Locke, Kant, Rawls,Dworkin), a communitarian model (MacIntyre, Sandel, Nussbaum) and (...) a communicative/deliberativemodel (Walzer, Benhabib, Taylor, Habermas). Numerous contradictions and tensionsbetween concepts of democracy and education can be found in such a juxtaposition,depending on which conception of democracy one chooses to apply. In this articleI discuss which conception affords us the most meaningful concept of democraticteaching. As an introduction, a brief historical overview of the interplay betweendemocracy and education in Danish school is provided. (shrink)

Joshua Greene argues that cognitive (neuro)science matters for ethics in two ways, the “direct route” and the “indirect route.” Greene illustrates the direct route with a debunking explanation of the inclination to condemn all incest. The indirect route is an updated version of Greene’s argument that dual-process moral psychology gives support for consequentialism over deontology. I consider each of Greene’s arguments, and I argue that neither succeeds. If there is a route from cognitive (neuro)science to ethics, Greene has not found (...) it. (shrink)

Engaging civil society actors as knowledgeable dialogue partners in the development and governance of emerging technologies is a new challenge. The starting point of this paper is the observation that the design and orchestration of current organized interaction events shows limitations, particularly in the articulation of issues and in learning how to address the indeterminacies that go with emerging technologies. This paper uses Dewey’s notion of ‘publics’ and ‘reflective inquiry’ to outline ways of doing better and to develop requirements for (...) a more productive involvement of civil society actors. By studying four novel spaces for interaction in the domain of nanotechnology, this paper examines whether and how elements of Dewey’s thought are visible and under what conditions. One of the main findings is that, in our society, special efforts are needed in order for technology developers and civil society actors to engage in a joint inquiry on emerging nanotechnology. Third persons, like social scientists and philosophers, play a role in this respect in addition to external input such as empirically informed scenarios and somewhat protected spaces. (shrink)
