This paper presents a dialogue system called Lorenzen–Hamblin Natural Dialogue (LHND), in which participants can commit formal fallacies and have a method of both identifying and withdrawing formal fallacies. It therefore provides a tool for the dialectical evaluation of force of argument when players advance reasons which are deductively incorrect. The system is inspired by Hamblin’s formal dialectic and Lorenzen’s dialogical logic. It offers uniform protocols for Hamblin’s and Lorenzen’s dialogues and adds a protocol for embedding them. This unification required (...) a reformulation of the original description of Lorenzen’s system to distinguish “between different stances that a person might take in the discussion”, as suggested by Hodges. The LHND system is compared to Walton and Krabbe’s Complex Persuasion Dialogue using an example of a dialogue. (shrink)

Building on our diverse research traditions in the study of reasoning, language and communication, the Polish School of Argumentation integrates various disciplines and institutions across Poland in which scholars are dedicated to understanding the phenomenon of the force of argument. Our primary goal is to craft a methodological programme and establish organisational infrastructure: this is the first key step in facilitating and fostering our research movement, which joins people with a common research focus, complementary skills and an enthusiasm to work (...) together. This statement—the Manifesto—lays the foundations for the research programme of the Polish School of Argumentation. (shrink)

Most studies on bilingual language development focus on children’s second language (L2). Here, we investigated first language (L1) development of Polish-English early migrant bilinguals in four domains: vocabulary, grammar, phonological processing and discourse. We first compared Polish language skills between bilinguals and their Polish non-migrant monolingual peers, and then investigated the influence of the cumulative exposure to L1 and L2 on bilinguals’ performance. We then examined whether high exposure to L1 could possibly minimize the gap between monolinguals and bilinguals. We (...) analyzed data from 233 typically developing children (88 bilingual, 145 monolingual) aged 4;0 to 7;5 (years; months) on six language measures in Polish: receptive vocabulary, productive vocabulary, receptive grammar, productive grammar (sentence repetition), phonological processing (non-word repetition) and discourse abilities (narration). Information about language exposure was obtained via parental questionnaires. For each language task, we analyzed the data from the subsample of bilinguals who had completed all the tasks in question and from monolinguals matched one-on-one to the bilingual group on age, SES (measured by years of mother’s education), gender, non-verbal IQ and short term memory. The bilingual children scored lower than monolinguals in all language domains, except discourse. The group differences were more pronounced on the productive tasks (vocabulary, grammar, phonological processing) and moderate on the receptive tasks (vocabulary and grammar). L1 exposure correlated positively with the vocabulary size and phonological processing. Grammar scores were not related to the levels of L1 exposure, but were predicted by general cognitive abilities. L2 exposure negatively influenced productive grammar in L1, suggesting possible L2 transfer effects on L1 grammatical performance. Children’s narrative skills benefitted from exposure to two languages: both L1 and L2 exposure influenced story structure scores in L1. Importantly, we did not find any evidence (in any of the tasks in which the gap was present) that the performance gap between monolinguals and bilinguals could be fully closed with high amounts of L1 input.

In September 2018, the ArgDiaP association, along with colleagues from Germany and the UK, organised one of the longest and most interdisciplinary series of events ever dedicated to argumentation - Warsaw Argumentation Week, WAW 2018. The eleven-day ‘week’ featured a five day graduate school on computational and linguistic perspectives on argumentation (3rd SSA school); five workshops: on systems and algorithms for formal argumentation (2nd SAFA), argumentation in relation to society (1st ArgSoc), philosophical approaches to argumentation (1st ArgPhil), legal argumentation (2ndMET-ARG) (...) and argumentation in rhetoric (1st MET-RhET); and two conferences: on computational models of argumentation (7th COMMA conference) and on argumentation and corpus linguistics (16th ArgDiaP conference). WAW hosted twelve tutorials and eight invited talks as well as welcoming over 130 participants. All the conferences and workshops publish pre- or post-proceedings in the top journals and book series in the field. (shrink)

Das politische Denken Rousseaus ist von einer tief greifenden Ambivalenz durchzogen: Einerseits soll mit der Republik die verlorene Einheit des Menschen auf politischer Ebene zurückgewonnen werden - doch andererseits bleibt angesichts der unheilbaren Spaltung des vergesellschafteten Menschen jede Hoffnung auf Einheit vergeblich. Magdalena Scherl rekonstruiert diesen Zwiespalt, indem sie das Republikideal im Lichte der Geschlechter- und Begehrenstheorie analysiert und dabei neben Rousseaus politischen Schriften auch sein literarisches Werk einbezieht. So werden die Aporien und Abgründe des republikanischen Denkens ausgeleuchtet, das (...) sich im Spannungsfeld zwischen ersehnter Einheit und unheilbarer Spaltung bewegt. (shrink)

En este trabajo presentamos un registro de la historia de vida de Mónica Medina, integrante de la comunidad weenhayek Quebracho, ubicada a 5 kilómetros de Tartagal, provincia de Salta. En esa memoria sobre sus ancestros desde tres generaciones previas hasta el presente, Mónica relata los recuerdos sobre el modo en que su familia vivió la Guerra del Paraguay que les obligó a desplazarse; las epidemias; el proceso de trashumancia y las distintas expulsiones a que se vieron sometidos; los modos en (...) que se fue transformando la vida a medida que se acercaban a los centros urbanos; la aproximación a la política partidaria y la formación de dirigentes; el proceso de conformación de demandas de reconocimiento de identidad étnica y las expectativas de futuro. Partimos de entender que este relato de vida, si bien es individual, se inscribe en la memoria colectiva de su familia, su comunidad y su pueblo, por cuanto resulta de experimentar, desde su trayectoria, ciertos recuerdos comunes. Este registro adquiere aquí un doble sentido epistémico: por un lado, permite conocer datos nodales sobre las trayectorias y las demandas actuales del Pueblo Weenhayek en torno a sus derechos a la identidad en Argentina, y particularmente sobre la disputa que libra por el reconocimiento estatal y social de su carácter de pueblo preexistente; pero a la vez, nos introduce en el trabajo de memoria que es central en el proceso de etnicidad que protagonizan estas comunidades weenhayek en su demanda y ejercicio de derechos actuales.

This thesis introduces a new theoretical tool to explore the notion of time and temporal order in quantum mechanics: the relativistic quantum "clock" framework. It proposes novel thought experiments showing that proper time can display quantum features, e.g. when a "clock" runs different proper times in superposition. The resulting new physical effects can be tested in near-future laboratory experiments (with atoms, molecules and photons as "clocks"). The notion of time holds the key to the regime where quantum theory and general (...) relativity overlap, which has not been directly tested yet and remains largely unexplored by the theory. The framework also applies to scenarios in which causal relations between events become non-classical and which were previously considered impossible to address without refuting quantum theory. The relativistic quantum "clock" framework offers new insights into the foundations of quantum theory and general relativity. (shrink)

International dispute resolution in general and international arbitration, in particular, is highly affected by the emergence and fast development of innovation-driven technologies. On the one hand, such technologies are cost and time-effective. To name a few, they allow online filing of a case, collecting of e-evidence and remote hearings, among others. On the other hand, they also may lead to some challenges that need to be addressed. The primary concerns comprise e-arbitration agreements and e-awards, as well as cybersecurity and data (...) protection. Therefore, this begs the question of whether such new technologies will significantly impact the dispute resolution landscape and thus become a game-changer therein. This analysis leads to the conclusion that the emergence of new technologies provides an opportunity to establish a long-lasting new standard for international arbitration. (shrink)

Love is a universal experience that most people desire. A serious, long-term, and stigmatized illness makes entering and maintaining close relationships difficult, however. Ten persons, who have been diagnosed with schizophrenia, and lived with their illness for between years and decades of their lifetimes, shared their stories. They reported how the illness has influenced their emotional experiences regarding love and their intimate relationship experiences. We present here a qualitative Interpretative Phenomenological analysis (IPA) of their narratives. This analysis has been done (...) with an explicit intention to give voice to the patient’s perspective. The results highlight how illness adjustment and hospitalizations have an alienating effect on relationships through stigmatization and self-stigmatization; how illness creates psychological obstacles to love, such as diminished trust toward oneself and others; and how long-term patients experience practical difficulties in creating and sustaining relationships, such as poverty. Moreover, we show how patients experience changes in sexuality and the risks involved in it, and discuss possible coping strategies from their perspectives. (shrink)

In this paper we have two main aims. First, we present an account of mood-congruent delusions in depression (hereafter, depressive delusions). We propose that depressive delusions constitute acknowledgements of self-related beliefs acquired as a result of a negatively biased learning process. Second, we argue that depressive delusions have the potential for psychological and epistemic benefits despite their obvious epistemic and psychological costs. We suggest that depressive delusions play an important role in preserving a person’s overall coherence and narrative identity at (...) a critical time, and thus can be regarded as epistemically innocent.

This paper refutes the widespread view that disjunctions of imperatives invariably grant free choice between the actions named by their disjuncts. Like other disjunctions they can also express a correlation with some factual distinction, but as with modalized declaratives used for non-assertive speech acts this needs to be indicated explicitly. A compositional analysis of one such indicator, depending on, constitutes the point of departure for a uniform analysis of disjunctions across clause types. Disjunctions are analyzed as sets of propositional alternatives (...) that correlate with a partition that the speaker may or may not be able to indicate explicitly. Free choice arises as the specific case where the partition is induced by the preferences of the addressee. (shrink)

Case, agreement, and A-movement dependencies across finite clause boundaries, such as Hyperraising or Long-Distance Case or Agreement [LDA], are available in many typologically diverse languages. The research on such dependencies typically distinguishes between cross-linguistically restricted true A-dependencies across finite clauses, and generally available binding-like A′-dependencies as found in Prolepsis. In this paper, we investigate both types of configurations in parallel and refer to this as the A-domain. Since the diagnostics to distinguish A-configurations vary across languages and often cannot be compared (...) directly, we define four characteristic properties: whether the construction is restricted by matrix predicate selection, whether movement in the embedded clause is involved, whether the dependency shows locality restrictions, and whether there are semantic restrictions on the relevant DP. By combining different values of the characteristic properties, we show, differently from previous approaches, that the A-domain does not simply consist of two types of configurations, but that the empirical landscape represents a continuum of five A-constructions. We suggest a theoretical implementation of our empirical findings, which is built on a predicational relator phrase above the embedded CP and propose that, in some of the constructions, these two projections fuse into one. We employ a minimalist probing approach which relies on differences in the base-generated position of the relevant DP, differences in the feature composition of the embedded C, a composite probe hierarchy yielding three types of feature-dependencies of composite probes, and, resulting from that, different probing mechanisms. Lastly, this paper also contributes methodological tools for disentangling constructions of the A-domain. (shrink)

While social research has documented the prevalence and ill effects of hepatitis C related stigma, there has been little analysis of the ways in which this stigma is constituted. This article addresses this gap in the literature by providing a phenomenologically informed account of the ways in which societal attitudes and regulations draw from and feed back into corporeal processes and experiences of embodiment in the creation of hepatitis C related stigma. The case is made that three components are central (...) to hepatitis C stigma: associations with illicit drug injecting, infectiousness and societal aversion to chronic illness. The article draws upon qualitative interviews with 40 people living with chronic hepatitis C in New Zealand and Australia, as well as the researcher’s embodied experience of living with the virus. The works of Julia Kristeva and Mary Douglas are utilized to provide an analysis that moves beyond acknowledgement of societal reinforcers of stigma, such as prohibitory drug laws, to address underlying notions of boundary crossing in the production of stigma and exclusionary practices.

Background Teamwork in emergency medical services is a very important factor in efforts to improve patient safety. The potential differences of staff gender on communication, patient safety, and teamwork were omitted. The aim of this study is to evaluate these inadequately examined areas. Methods A descriptive and anonymous study was conducted with an online questionnaire targeting emergency physicians and paramedics. The participants were asked about teamwork, communication, patient safety and handling of errors. Results Seven hundred fourteen prehospital professionals from all (...) over Germany participated. A total of 65.7% of the women harmed a patient (men 72.9%), and 52.6% were ashamed when mistakes were made (men 31.7%). 19.0% of the female participants considered their communication skills to be very good, compared to 81% of the men. More women than men did not want to appear incompetent (28.4%, 15.5%) and therefore did not speak openly about mistakes. Both genders saw the character of their colleagues as a reason for poor team communication (women 89.4%, men 84.9.%). Under high stress, communication decreased (women 35.9%, men 31.0%) and expression became inaccurate (women 18.7%, men 20.1%). Conclusions Team communication problems and teamwork in rescue services are independent of gender. Women seem to have more difficulty with open communication about mistakes because they seem to be subject to higher expectations. Work organization should be adapted to women’s needs to enable more effective error management. We conclude that it is necessary to promote a positive error and communication culture to increase patient safety. (shrink)

Background International electives are often considered a valuable learning opportunity for medical students. Yet, as travelling to lower and middle income countries (LMICs) becomes more common, ethical considerations of such practices emerge. We conducted a scoping review to assess the extent to which five ethical themes were addressed in existing literature about electives, with the aim of investigating the ethical impacts of medical student electives on local resources, patients and clinicians in LMICs. Methods We systematically searched PubMed, Global Health and (...) Embase databases using the search terms “(ethics) AND (medical electives)”. Thematic content analysis was undertaken using a combination of deductive and inductive themes. The deductive themes included: exceeding clinical competence, use of limited local resources, respect for patients and local culture, collaboration with local community/colleagues, and one-sided benefits in partnership. In addition, we also allowed for emerging themes within the data, and conducted a narrative synthesis of the results. Results A total of 37 papers discussed ethical issues relating to medical student international electives to LMICs. More publications were written from the medical student perspective (n = 14), than by the host-institution (n = 5), with nearly half written from third-party perspectives (n = 18). Negative impacts on local host students and impact upon patient care were identified as additional ethical considerations. Conclusions Our review demonstrated that while there is a degree of awareness in the existing literature of the potential negative impacts of medical electives to local LMIC students’ access to medical education and patient care, continued work is needed to ensure equitable partnerships. We recommend that these ethical themes should be further explored in pre-departure elective teaching courses and post-elective debriefs to increase medical students’ awareness of the impact of their presence on host communities.

Mild and massive DNA damage are differentially integrated into the cellular signaling networks and, in consequence, provoke different cell fate decisions. After mild damage, the tumor suppressor p53 directs the cellular response to cell cycle arrest, DNA repair, and cell survival, whereas upon severe damage, p53 drives the cell death response. One posttranslational modification of p53, phosphorylation at Serine 46, selectively occurs after severe DNA damage and is envisioned as a marker of the cell death response. However, the molecular mechanism (...) of action of the p53 Ser46 phospho‐isomer, the molecular timing of this phosphorylation event, and its activating effects on apoptosis and ferroptosis still await exploration. In this essay, the current body of evidence on the molecular function of this deadly p53 mark, its evolutionary conservation, and the regulation of the key players of this response, the p53 Serine 46 kinases, are reviewed and dissected.

According to general relativity, we live in a four-dimensional curved universe. Since the human mind cannot visualize those four dimensions, a popular analogy compares the universe to a two-dimensional rubber sheet distorted by massive objects. This analogy is often used when teaching GR to upper secondary and undergraduate physics students. However, physicists and physics educators criticize the analogy for being inaccurate and for introducing conceptual conflicts. Addressing these criticisms, we analyze the rubber sheet analogy through systematic metaphor analysis of textbooks (...) and research literature, and present an empirical analysis of upper secondary school students’ use and understanding of the analogy. Taking a theoretical perspective of embodied cognition allows us to account for the relationship between the experiential and sensory aspects of the metaphor in relation to the abstract nature of spacetime. We employ methods of metaphor and thematic analysis to study written accounts of small groups of 97 students who worked with a collaborative online learning environment as part of their regular physics lessons in five classes in Norway. Students generated conceptual metaphors found in the literature as well as novel ones that led to different conceptions of gravity than those held by experts in the field. Even though most students showed awareness of some limitations of the analogy, we observed a conflict between students’ embodied understanding of gravity and the abstract description of GR. This conflict might add to the common perception of GR being counterintuitive. In making explicit strengths and weaknesses of the rubber sheet analogy and learners’ conceptual difficulties, our results offer guidance for teaching GR. More generally, these findings contribute to the epistemological implications of employing specific scientific metaphors in classrooms. (shrink)

Much of the excitement about virtual reality and its potential for things like entertainment, art, education, and activism is its ability to generate experiences that are powerfully immersive. However, discussions of VR tend to invoke the notion of immersive experience without subjecting it to closer scrutiny; and discussions often take it for granted that immersive experience is a single unified phenomenon. Against this, we argue that there are four distinct types or aspects of immersive experience that should be distinguished: representational (...) immersion, which corresponds roughly to what is sometimes called “psychological presence”; participatory immersion, which is related to the interactive aspects of VR experience; affective immersion, which has to do with the subject’s emotional relation to the experience; and narrative immersion, which captures the phenomenon of being caught up in the flow of events experienced. We argue that this four-way distinction helps us understand the powerfully immersive character of VR, while also recognizing its continuity with the immersion we experience with media such as novels, films, and music. We also argue that the account of immersion we offer here lets us better understand the connection between VR and empathy, charting a middle course between extreme enthusiasts who view VR as the ultimate “empathy machine” and extreme skeptics who argue that this attitude is misguided.

This paper deals with the problem of verification of game-like structures by means of symbolic model checking. Alternating-time Temporal Epistemic Logic (ATEL) is used for expressing properties of multi-agent systems represented by alternating epistemic temporal systems as well as concurrent epistemic game structures. Unbounded model checking (a SAT based technique) is applied for the first time to verification of ATEL. An example is given to show an application of the technique.

W archiwum osobistym Adama Tarna (1902–1975) – pierwszego redaktora naczelnego miesięcznika „Dialog”, tłumacza, krytyka, powieściopisarza, dramaturga – znajdują się zapiski z luźnymi pomysłami do utworów dramatycznych, notatki do nieukończonej książki o Czechowie, a także niewielkie próby literackie – poprawiane, odkładane i na powrót rozwijane. Materiały te udostępniane dzięki uprzejmości spadkobierców są cennym świadectwem procesu twórczego i ewolucji pisarstwa redaktora naczelnego „Dialogu”. W kontekście debiutanckiej i jedynej ukończonej powieści Tarna _Obraz ojca w czterech ramach _(1934) intrygującym utworem jest zachowana w archiwum (...) nieukończona powieść _Kameleon_. Artykuł charakteryzuje materiały znajdujące się w archiwum osobistym Tarna. Pozwala wniknąć w jego „wewnętrzne laboratorium” pisarskie i odczytać je m.in. w perspektywie biograficznej. Datowanie zgromadzonych materiałów można przyjąć jedynie orientacyjnie. Najwcześniejsza zachowana próba prozatorska zapisana po francusku pochodzi prawdopodobnie jeszcze z okresu międzywojennego. Ostatnie zapiski pochodzą z okresu emigracyjnego po 1968 roku, kiedy Tarn pracował nad nieukończoną książką o Czechowie. (shrink)

The aim of this paper is to present Tischner’s concept of ‘people from hideouts’ in the context of contemporary problems of lack of social involvement, characteristic of Polish society. According to Tischner’s intention, the concept of ‘people from hideouts’ is understood as a manifestation of the pathology of hope, which, in my opinion, is expressed in the reluctance to participate in social life and fulfill civic duties. The paper presents key issues for Tischner’s concept related to the role of hope (...) in human life and fear as an exemplification of an abandonment for hope. The text also describes concepts related to values, freedom, and the role of encounter and dialogue in interpersonal relations. (shrink)
