The traditional view of cognition as detached from emotions is recently being questioned. This study aimed to investigate the influence of emotional valence on the accuracy and bias in the representation of numbers on the mental number line (MNL). The study included 164 participants who were randomly assigned into two groups with induced positive and negative emotional valence using matched arousal film clips. Participants performed a computerised number-to-position (CNP) task to estimate the position of numbers on a horizontal line. The (...) results showed that participants in the positive valence group exhibited a rightward bias, while those in the negative valence group showed an opposite pattern. The analysis of mean absolute error revealed that the negative valence group had higher error rates compared to the positive valence group. Furthermore, the MNL estimation pattern analysis indicated that a two-cycle cyclic power model (CPM) best explained the data for both groups. These findings suggest that emotional valence influences the spatial representation of numbers on the MNL and affects accuracy in numerical estimations. Our findings are finally discussed in terms of body-specificity and the Brain’s Asymmetric Frequency Tuning (BAFT) theories. The study provides new insights into the interplay between emotions and numerical cognition. (shrink)

Lee and Schwarz suggest that separation is the grounded procedure underlying cleansing effects in different psychological domains. Here, we interpret L&S's account from a hierarchical view of cognition that considers the influence of physical properties and sensorimotor constraints on mental representations. This approach allows theoretical integration and generalization of L&S's account to the domain of formal quantitative reasoning.

We focus here on the intercalary heterochromatin (IH) of Drosophila melanogaster and, in particular, its molecular properties. In the polytene chromosomes of Drosophila, IH is represented by a reproducible set of dense bands scattered along the euchromatic arms. IH contains mainly unique DNA sequences, and shares certain features with other heterochromatin types such as pericentric, telomeric, and PEV‐induced heterochromatin, the inactive mammalian X‐chromosome and the heterochromatized male chromosome set in coccids. These features are transcriptional silencing, chromatin compactness, late DNA replication, (...) underrreplication or elimination in somatic cells, and formation of the heterochromatin state in early embryogenesis. Post‐translational modification of histones and the specific nonhistone protein complexes are shown to participate in the establishment and maintenance of silencing for all heterochromatin types. Many IH regions contain binding sites for HP1 and/or Pc‐G proteins and all the regions are sites of heterochromatin‐associated SuUR protein. Some IH regions are known to contain homeotic genes. Summarizing these data, we suggest that IH regions comprise stable inactivated genes, whose silencing is developmentally programmed. BioEssays 25:1040–1051, 2003. © 2003 Wiley Periodicals, Inc.

Three experiments investigated the role of target-target perceptual similarity within the attentional blink. Various geometric shapes were presented in a rapid serial visual presentation task. Targets could have 2, 1, or 0 shared features. Features included shape and size. The second target was presented after five or six different lags after the first target. The task was to detect both targets on each trial. Second-target report accuracy was increased by target-target similarity. This modulation was observed more for mixed-trial design as (...) compared with blocked design. Results are discussed in terms of increased stability of working memory representations and reduced interference for second-target processing. (shrink)

The most enigmatic feature of polytene chromosomes is their banding pattern, the genetic organization of which has been a very attractive puzzle for many years. Recent genome‐wide protein mapping efforts have produced a wealth of data for the chromosome proteins of Drosophila cells. Based on their specific protein composition, the chromosomes comprise two types of bands, as well as interbands. These differ in terms of time of replication and specific types of proteins. The interbands are characterized by their association with (...) “active” chromatin proteins, nucleosome remodeling, and origin recognition complexes, and so they have three functions: acting as binding sites for RNA pol II, initiation of replication and nucleosome remodeling of short fragments of DNA. The borders and organization of the same band and interband regions are largely identical, irrespective of the cell type studied. This demonstrates that the banding pattern is a universal principle of the organization of interphase polytene and non‐polytene chromosomes.Editor's suggested further reading in BioEssaysCaught in the act: Rapid, symbiont‐driven evolution AbstractFunction and evolution of sex determination mechanisms, genes and pathways in insects Abstract.

Tematyka prepozytury szpitalnej w Zebrzydowicach jest ściśle związana z osobą Mikołaja Zebrzydowskiego, który w 1599 roku ufundował w rodowej siedzibie szpital dla 12 weteranów wojskowych, przede wszystkim dla tych, którzy należeli do bractwa żołnierskiego świętego Michała Archanioła założonego przez wojewodę w 1596 roku. W jego zamierzeniu przebywający tam chorzy mieli otrzymać odpowiednią opiekę zarówno dla ciała, jak i dla duszy, dlatego też zarząd przytułku oraz troskę o potrzeby pacjentów zostały powierzone miejscowemu proboszczowi, który był zarazem prepozytem tegoż szpitala. Z czasem (...) okazało się, iż takie rozwiązanie nie zadowalało fundatora i ostatecznie zdecydował on o przekazaniu tego dzieła braciom bonifratrom, których sprowadził do Zebrzydowic z Krakowa w 1611 roku. W niniejszym artykule został ukazany jeden z etapów procesu poszukiwania lepszego sposobu na zarządzanie równocześnie fundacją i parafią, który Zebrzydowski spróbował wcielić w życie już w 1601 roku. Niepublikowany dotąd dokument biskupa Bernarda Maciejowskiego z 3 sierpnia 1601 roku, oblatowany w aktach czynności biskupa krakowskiego (edycja wraz z tłumaczeniem w aneksie), wprowadzał rozwiązanie dążące do utrzymania prepozytury kosztem miejscowej parafii, zaś osobą łączącą obie jednostki administracyjne miał być od tej pory prepozyt, a nie proboszcz. Dokument ten stanowi zarazem ciekawy przykład współpracy biskupa ze szlachtą w sprawach kościelnych, co było niezwykle istotne w ówczesnym systemie zależności pomiędzy kolatorami miejscowego kościoła a biskupem ordynariuszem, odpowiedzialnym za całość życia kościelnego na terytorium zarządzanej przez siebie diecezji.

We are offering you a new issue of _The Ignatianum Philosophical Yearbook_. It is almost entirely devoted to Mikołaj Zebrzydowski. The state of research on him is outlined in the first article by Elżbieta E. Wróbel and Tomasz Graff. In a separate article, the latter author also presents issues related to the development of Florian Zebrzydowski’s estate as his political importance grew at the court of King Sigismund Augustus. Special emphasis was placed on the case study method here. The author (...) analyzes Zebrzydowski’s acquisition of property in Radocza near Wadowice, showing the prospect of the need for further research into the growth of the estate of Florian Zebrzydowski and his family. The article concludes with an appendix, including an edition in Latin and a Polish translation of the document, in which “Sigismund Augustus grants Florian Zebrzydowski the right to build a dam on the Skawa River and to run water from there through a moat across the area of the Wadowice estate to build fish ponds in the Radocza estate.”.

This study investigates the online process of reading and analyzing of sketchnotes (visual notes containing a handwritten text and drawings) on Russian language material. Using the eye-tracking method, we compared the processing of different types of sketchnotes (‘path’ (trajectory), linear, and radial) and the processing of a verbal text. Biographies of Russian writers were used as the material. In a preliminary experiment, we asked 89 college students to read the biographies and to evaluate each text or sketch using five scales (...) (from -2 to +2). The best example for each of three formats of sketchnotes and a verbal text were chosen. In the main experiment, twenty-one secondary school students examined four different biographies in four different formats (three sketchnotes and a verbal text), answered to the factual and analytical questions to these texts and estimated the difficulty of each text. We measured the total dwell time, the total fixation count, the average fixation duration for each stimulus as well as for separate zones inside the sketches including verbal and non-verbal information. Our results show that readers process the information better and faster while reading sketchnotes than a verbal text. In the trajectory sketchnotes, the readers followed the order of elements aimed by the author of the sketchnotes better than in the radial and linear sketchnotes. The analysis of participants’ eye movements while processing the stimuli made it possible to propose several recommendations for creating effective sketchnotes. (shrink)

The justification of democracy, while widely debated, is hindered by a sub-optimal conceptual framework. For a start, there is confusion about the basic terms in the discussion. Many theorists claim to support either the ‘intrinsic’ or the ‘instrumental’ value of democracy, but it is unclear what this exactly means. Can democracy have other kinds of values? What does it mean to value democracy intrinsically? As a result, at certain points, scholars are talking past one another and their assessments of their (...) respective approaches to democracy are less clear than what they intended. This paper develops a conceptual framework of the values of democracy. I use this framework to classify theories of democracy under three main groups: theories that value democracy intrinsically, instrumentally, or contributorily (necessarily and non-necessarily). Through this analysis, the points of engagement among the different approaches will emerge and flawed arguments about democracy will be revealed. (shrink)

Is there more that one "Curie's principle"? How far are different formulations legitimate? What are the aspects that make it so scientifically fruitful, independently of how it is formulated? The paper is devoted to exploring these questions. We start with illustrating Curie's original 1894 article and his focus. Then, we consider the way that the discussion of the principle took shape from early commentators to its modern form. We say why we think that the modern focus on the inter-state version (...) of the principle loses sight of some of the most interesting significant applications of the principle. Finally, we address criticism of the principle put forward by Norton and purported counterexamples due to Roberts. (shrink)

This paper investigates the concept of behavioral autonomy in Artificial Life by drawing a parallel to the use of teleological notions in the study of biological life. Contrary to one of the leading assumptions in Artificial Life research, I argue that there is a significant difference in how autonomous behavior is understood in artificial and biological life forms: the former is underlain by human goals in a way that the latter is not. While behavioral traits can be explained in relation (...) to evolutionary history in biological organisms, in synthetic life forms behavior depends on a design driven by a research agenda, further shaped by broader human goals. This point will be illustrated with a case study on a synthetic life form. Consequently, the putative epistemic benefit of reaching a better understanding of behavioral autonomy in biological organisms by synthesizing artificial life forms is subject to doubt: the autonomy observed in such artificial organisms may be a mere projection of human agency. Further questions arise in relation to the need to spell out the relevant human aims when addressing potential social or ethical implications of synthesizing artificial life forms. (shrink)

The medical drama and its central character, the doctor-hero have been a mainstay of popular television. House M.D. offers a new (and problematic) iteration of the doctor-hero. House eschews the generic conventions of the “television doctor” by being neither the idealized television doctor of the past, nor the more recent competent but often fallible physicians in entertainment texts. Instead, his character is a fragmented text which privileges the biomedical over the personal or emotional with the ultimate goal of scientifically uncovering (...) and resolving instances of disease. This article examines the implicit and explicit messages in House M.D. and critically analyzes both the show and its lead character in relation to the traditional medical drama genre that highlights the “doctor-hero” as the central character. While at first House seems to completely violate narrative and generic norms, ultimately the program provides a new form that reinforces the presence of the doctor-hero, but highlights House’s character as the central figure who is personally and interpersonally problematic but biomedically effective.

East Asia’s economy is leading the world into the new Asian century. While meritocratic practices in the educational and private sectors are often considered pivotal conditions for East Asia’s economic success, experts have pointed out that the path ahead requires new approaches to ensure social cohesion and stability, which depend on the quality of relations across social divides. These considerations raise multiple questions for philosophers: What forms of social meritocracy are necessary to sustain social cohesion? Moreover, how can the detrimental (...) effects of meritocratic practices be contained? Is it possible to utilise some of the intellectual resources indigenous to East Asia to generate innovative solutions? This paper argues that the answers to these questions lie in the indigenous Confucian conceptual resources. Confucian ideas can inspire a more desirable societal ideal for the future of East Asia. In particular, the Confucian emphasis on cultivating reciprocal harmonious human relationships and others’ morality can guide new approaches to fostering social cohesion. As Confucian personal cultivation through harmonious relations is a process of social cohesion, these ideas inspire a) a multiple approach to policymaking that is not only grounded in economic redistribution, b) a richer understanding of societal progress, and c) a democratic approach to fostering social cohesion. Unlike Confucian meritocrats and scholars who defend the Confucian roots of East Asian forms of political and social meritocracy, this paper proves that Confucian conceptual resources can help formulate a societal vision that strengthens cohesion and mitigates the adverse effects of meritocratic practices.

Quantum violation of Bell inequalities is now used in many quantum information applications and it is important to analyze it both quantitatively and conceptually. In the present paper, we analyze violation of multipartite Bell inequalities via the local probability model—the LqHV model, incorporating the LHV model only as a particular case and correctly reproducing the probabilistic description of every quantum correlation scenario, more generally, every nonsignaling scenario. The LqHV probability framework allows us to construct nonsignaling analogs of Bell inequalities and (...) to specify parameters quantifying violation of Bell inequalities—Bell’s nonlocality—in a general nonsignaling case. For quantum correlation scenarios on an N-qudit state, we evaluate these nonlocality parameters analytically in terms of dilation characteristics of an N-qudit state and also, numerically—in d and N. In view of our rigorous mathematical description of Bell’s nonlocality in a general nonsignaling case via the local probability model, we argue that violation of Bell inequalities in a quantum case is not due to violation of the Einstein–Podolsky–Rosen locality conjectured by Bell but due to the improper HV modelling of “quantum realism”.

Language used to describe measles in the press has altered significantly over the last sixty years, a shift that reflects changing perceptions of the disease within the medical community as well as broader changes in public health discourse. California, one of the most populous U.S. states and seat of the 2015 measles outbreak originating at Disneyland, presents an opportunity for observing these changes. This article offers a longitudinal case study of five decades of measles news coverage by the Los Angeles (...) Times and the San Francisco Chronicle, which represented two of the largest news markets in California when the measles vaccine was released, in 1963, and during the 2015 outbreak. Measles reporting during this period displays patterns pointing to an active role for journalists in shaping public understanding of health and medical matters, especially as they recede from public memory, through the employment of available and circulating political and cultural frames. Moreover, journalistic frames in this period of reporting incorporated presentist descriptions of the disease, which imposed present values on the medical past, and which were constructed of decontextualized historical references that supported prevailing contemporary notions of the disease. Framing and the tendency toward presentism, in the context of shifting public health discourse, had the effect of communicating an increasingly severe sounding disease over time, and of shifting blame for that disease’s spread from nature to government to individuals. Journalistic framing and causal stories have much power to shape public understanding of medical matters as they recede from public memory. (shrink)

Some authors have claimed that Hegel's ‘determinate negation’ should be distinguished from ‘logical’ or ‘formal’ negation, that is, from a view of negation as a contradictory forming operator. In contrast, I argue that dialectical determinate negation involves a view of negation as a contradictory forming operator, and can therefore count as formal negation in every respect. However, as it is clear in contemporary glutty semantics of negation, one may distinguish between different accounts of the relationship between negation, contradiction and content. (...) I suggest that, differently from classical negation, and as glutty negation, dialectical negation has partial content. (shrink)

This book is a consideration of Hegel’s view on logic and basic logical concepts such as truth, form, validity, and contradiction, and aims to assess this view’s relevance for contemporary philosophical logic. The literature on Hegel’s logic is fairly rich. The attention to contemporary philosophical logic places the present research closer to those works interested in the link between Hegel’s thought and analytical philosophy, Koch 2014, Brandom 2014, 1-15, Pippin 2016, Moyar 2017, Quante & Mooren 2018 among others). In this (...) context, one particularity of this book consists in focusing on something that has been generally underrated in the literature: the idea that, for Hegel as well as for Aristotle and many other authors, logic is the study of the forms of truth, i.e. the forms that our thought can assume in searching for truth. In this light, Hegel’s thinking about logic is a fundamental reference point for anyone interested in a philosophical foundation of logic. (shrink)

This paper is concerned with the problem of the validity of Leibniz's principle of the identity of indiscernibles in physics. After briefly surveying how the question is currently discussed in recent literature and which is the actual meaning of the principle for what concerns physics, we address the question of the physical validity of Leibniz's principle in terms of the existence of a sufficient number of naming predicates in the formal language of physics. This approach allows us to obtain in (...) a formal way the result that a principle of the identity of indiscernibles can be justified in the domain of classical physics, while this is not the case in the domain of quantum physics.

This paper discusses Simone de Beauvoir’s views on the meaning of life as presented in The Ethics of Ambiguity. I argue that Beauvoir’s view matches contemporary hybrid views on the meaning of life, incorporating both subjective and objective elements, while connecting them in a distinct way—through the tension between self and other. I then analyze the meaning of excessively competitive projects through Beauvoir’s ethics and conclude that success that amounts to denying other people’s access to the things one values is (...) absurd. I use the case of contemporary academia as an illustration of extreme competition, then employ Beauvoir’s views to suggest a shift towards more meaningful practices. (shrink)

In this paper, I propose a logical-cognitive approach to argumentation and advocate an idea that argumentation presupposes that intelligent agents engaged in it are cognitively diverse. My approach to argumentation allows drawing distinctions between justification, conviction and persuasion as its different kinds. In justification agents seek to verify weak or strong coherency of an agent’s position in a dialogue. In conviction they argue to modify their partner’s position by means of demonstrating weak or strong cogency of their positions before a (...) ‘rational judge’. My approach to argumentation employs a ‘light’ version of Dung’s abstract argumentative frameworks. It is based on Stich’s idea of agents’ cognitive diversity the epistemic aspect of which is argued to be close to Pavilionis’s conception of meaning continuum. To illustrate my contributions I use an example based on the Kitchen Debate (1959) between Khrushchev and Nixon. (shrink)

One of the aims of Gadamer’s hermeneutic ontology is the definition of the specific character of the human sciences. Gadamer maintains that their method is based upon the acknowledgement of the authority of tradition. Hence the main problem that faces his theory is the question of what makes the investigation in the humanities scientific and innovative. In my paper I try to reconstruct Gadamer’s solution of this problem. I consider his notion of tradition and its role in the definition of (...) understanding as a cognition of truth. For Gadamer tradition is a precondition both of all possibility of understanding and of the historicity of the hermeneutic happening. This conception permits to define how the human sciences grasp the reality and what is studied by them. (shrink)

Adam Ferguson’s imperial thought casts new light on the age-old republican dilemma of the tension between empire and liberty. Generations of republican writers had been haunted by this issue as the decline of Rome proved that imperial expansion would eventually ruin the liberty of a state. Many eighteenth-century Scottish thinkers regarded this as an insoluble conundrum and thus became critics of empire. Ferguson shared their basic views but, paradoxically, was still able to defend the British Empire in the debates over (...) the American Revolution. His argument effectively offered a viable solution to the republican dilemma, which distinguished him from his contemporaries. In light of this, I argue that political representation was the pivotal conception for Ferguson to make empire and liberty compatible. It was on this ground that he could advocate the union with Ireland, which he believed would lead to a lasting balance of power in Europe. -/- ; British Empire; liberty; balance of power; political representation; American Revolution; Anglo-Irish Union.

The enactive approach to cognition distinctively emphasizes autonomy, adaptivity, agency, meaning, experience, and interaction. Taken together, these principles can provide the new sciences of language with a comprehensive philosophical framework: languaging as adaptive social sense-making. This is a refinement and advancement on Maturana’s idea of languaging as a manner of living. Overcoming limitations in Maturana’s initial formulation of languaging is one of three motivations for this paper. Another is to give a response to skeptics who challenge enactivism to connect “lower-level” (...) sense-making with “higher-order” sophisticated moves like those commonly ascribed to language. Our primary goal is to contribute a positive story developed from the enactive account of social cognition, participatory sense-making. This concept is put into play in two different philosophical models, which respectively chronicle the logical and ontogenetic development of languaging as a particular form of social agency. Languaging emerges from the interplay of coordination and exploration inherent in the primordial tensions of participatory sense-making between individual and interactive norms; it is a practice that transcends the self-other boundary and enables agents to regulate self and other as well as interaction couplings. Linguistic sense-makers are those who negotiate interactive and internalized ways of meta-regulating the moment-to-moment activities of living and cognizing. Sense-makers in enlanguaged environments incorporate sensitivities, roles, and powers into their unique yet intelligible linguistic bodies. We dissolve the problematic dichotomies of high/low, online/offline, and linguistic/nonlinguistic cognition, and we provide new boundary criteria for specifying languaging as a prevalent kind of human social sense-making.

This essay argues that according to feminist existential phenomenology, feminist pragmatism, and feminist genealogy, our embodied condition is an important starting place for ethical living due to the inevitable role that habits play in our conduct. In bodies, the phenomenon of habit uniquely holds together the ambiguities of freedom and determinism, transcendence and immanence, and stability and plasticity. Seeing habit formation as a matter of self-growth and social justice gives fresh opportunity for thinking of “assuming ambiguity” as a lifelong endeavor (...) made up of many small projects and practices of situated resistance to stagnation. Transcendence, understood as ameliorative transformation, is found in cultivating habits of learning from our bodily living. I articulate this argument via a reading of Simone de Beauvoir's The Coming of Age, John Dewey's Human Nature and Conduct, and Ladelle McWhorter's Bodies and Pleasures. I discuss two domains wherein the ethical significance of habit formation appears: cognitive psychological research on neural plasticity, and certain projects of self-cultivation that risk turning into overdetermining “cult of the self ” practices that close off possibilities for personal and collective transformation.

Artykuł ukazuje w ujęciu problemowym stan badań nad postacią Mikołaja Zebrzydowskiego (1553–1620) oraz jego rodziny do roku 2022. Zwrócono uwagę na najważniejsze publikacje dotyczące jego biografii, fundacji oraz działalności politycznej. Zauważono, że dotychczasowa historiografia zajmowała się Zebrzydowskim głównie w kontekście rokoszu sandomierskiego, fundacji klasztoru, kalwarii oraz fundacji w rodowych Zebrzydowicach. Natomiast genealogią rodziny Zebrzydowskich, ich majątkiem oraz powiązaniami z innymi rodami zajmowano się sporadycznie. Nieco szerzej analizowano działalność Floriana Zebrzydowskiego, ojca Mikołaja, jednak głównie jako teoretyka wojskowości. Autorzy podkreślają szczególnie znaczenie (...) rocznicy 400-lecia śmierci wojewody krakowskiego, która przypadła na rok 2020. Przyczyniła się ona do intensyfikacji badań nad biografią Mikołaja Zebrzydowskiego i jego rodziną, co zaowocowało m.in. wydaniem dwóch monografii: szkicu biograficznego oraz pracy zbiorowej.

This article analyses the new demographic programme that was announced by the Russian president, Vladimir Putin, in 2006. The main goal of this programme is to encourage fertility, especially the birth of a second child. New benefits should elevate the status of wome taking maternity leave, who might otherwise suffer from discrimination in the family. The housewife is considered to be dependent and `degraded'. We argue that this demographic politics recalls continuity with soviet gender politics centred on the support of (...) wage-earning working mothers. The programme provokes different critiques. Liberal critics argue that the programme is a populist one and it may have undesired economic and social consequences. Conservative critics want to encourage more traditional `woman' and `family' roles in society. Feminist critics argue that this politcs would reinforce both the inferior position of women on the labour market and gender imbalances on the symbolic level. (shrink)

We tested the hypothesis that our ability to detect fine kinematics variations is tuned to reveal more subtle differences when the motion pattern belongs to the observer compared to another individual. To this purpose, we analyzed the responses of 15 subjects in a same-different task on pairs of movements, which could belong to one or two different subjects. Self vs. Other comparisons were obtained by presenting both the observer’s and another participant’s kinematics. Subjects responded faster and more accurately when they (...) observed their own gestures compared to movements of another participant. In the latter case, slight kinematic differences were more likely to remain undetected. These findings are discussed within an ecological framework: in observing others, we are more concerned with detection of goals and intentions, i.e., outstanding variations in motion patterns. Conversely, in self-observation detection of more subtle differences is required to facilitate learning and optimization of motor acts. (shrink)
