Observability is a modelling property that describes the possibility of inferring the internal state of a system from observations of its output. A related property, structural identifiability, refers to the theoretical possibility of determining the parameter values from the output. In fact, structural identifiability becomes a particular case of observability if the parameters are considered as constant state variables. It is possible to simultaneously analyse the observability and structural identifiability of a model using the conceptual tools of differential geometry. Many (...) complex biological processes can be described by systems of nonlinear ordinary differential equations and can therefore be analysed with this approach. The purpose of this review article is threefold: to serve as a tutorial on observability and structural identifiability of nonlinear systems, using the differential geometry approach for their analysis; to review recent advances in the field; and to identify open problems and suggest new avenues for research in this area.

Indisciplinar el vestigio conlleva retornarle su potencia antimoderna y decolonial. Desde un mero punto de vista epistemológico sería abordar la simultanedidad como apertura al conocimiento, traspasar los umbrales divisorios de la ciencia colonial, conectar lo que la disciplina ha separado y fluir aquello que ha sido estancado. La arqueología es una herramienta fundamental del conocimiento contrahegemónico. Pero, al mismo tiempo, y dado que las relaciones evestigiales son simultáneas, estratificadas y constitutivas tanto del mundo como de nuestra relación en el mundo, (...) el otro lado del vestigio importa mucho más que una apertura al conocimiento.

In this contribution, we use the connection between stable polynomials and orthogonal polynomials on the real line to construct sequences of Hurwitz polynomials that are robustly stable in terms of several uncertain parameters. These sequences are constructed by using properties of orthogonal polynomials, such as the well-known three-term recurrence relation, as well as by considering linear combinations of two orthogonal polynomials with consecutive degree. Some examples are presented.

La discusión sobre el psicologismo lógico, que parecía ya superada desde Frege-Husserl, ha vuelto a posicionarse hoy en la filosofía de la lógica. Se examina, en primer lugar, la idea según la cual lo que hoy se entiende por lógica respondería en lo esencial a las tesis defendidas por el anti-psicologismo. En segundo término, se plantea que algunos enfoques actuales en ciencia cognitiva, como el de la facultad cognitiva proto-lógica de R.Hanna, y el de los dominios cognitivos, de Stennings y (...) van Lambalgen, permiten apoyar la idea de que la naturaleza de la lógica va más allá de los atributos antipsicologistas.

By a theorem of R. Kaye, J. Paris and C. Dimitracopoulos, the class of the Πn+1-sentences true in the standard model is the only consistent Πn+1-theory which extends the scheme of induction for parameter free Πn+1-formulas. Motivated by this result, we present a systematic study of extensions of bounded quantifier complexity of fragments of first-order Peano Arithmetic. Here, we improve that result and show that this property describes a general phenomenon valid for parameter free schemes. As a consequence, we obtain (...) results on the quantifier complexity, finite axiomatizability and relative strength of schemes for Δn+1-formulas. (shrink)

We study the quantifier complexity and the relative strength of some fragments of arithmetic axiomatized by induction and minimization schemes for Δn+1 formulas.

Despite pervasive variation in the content of laws, legal theorists and anthropologists have argued that laws share certain abstract features and even speculated that law may be a human universal. In the present report, we evaluate this thesis through an experiment administered in 11 different countries. Are there cross‐cultural principles of law? In a between‐subjects design, participants (N = 3,054) were asked whether there could be laws that violate certain procedural principles (e.g., laws applied retrospectively or unintelligible laws), and also (...) whether there are any such laws. Confirming our preregistered prediction, people reported that such laws cannot exist, but also (paradoxically) that there are such laws. These results document cross‐culturally and –linguistically robust beliefs about the concept of law which defy people's grasp of how legal systems function in practice. (shrink)

A well known theorem proved by J. Paris and H. Friedman states that BΣn +1 is a Πn +2-conservative extension of IΣn . In this paper, as a continuation of our previous work on collection schemes for Δn +1-formulas , we study a general version of this theorem and characterize theories T such that T + BΣn +1 is a Πn +2-conservative extension of T . We prove that this conservativeness property is equivalent to a model-theoretic property relating Πn-envelopes and (...) Πn-indicators for T . The analysis of Σn +1-collection we develop here is also applied to Σn +1-induction using Parsons' conservativeness theorem instead of Friedman-Paris' theorem.As a corollary, our work provides new model-theoretic proofs of two theorems of R. Kaye, J. Paris and C. Dimitracopoulos : BΣn +1 and IΣn +1 are Σn +3-conservative extensions of their parameter free versions, BΣ–n +1 and IΣ–n +1. (shrink)

The ICD-11 personality disorder model is the first fully dimensional assessment of personality pathology. It consists of a personality disorder dysfunction-severity dimension, which encompasses both self- and interpersonal dysfunction, and six optional qualifiers for five prominent personality traits—Negative Affectivity, Detachment, Dissociality, Disinhibition, and Anankastia —plus a borderline pattern that is defined by the criteria of DSM-IV borderline PD. This article reports on the development of a new self-report measure to assess self- and interpersonal dysfunction and the five trait qualifiers. It (...) is the first comprehensive measure of the ICD-11 PD model in that it is the only one to include both PD dysfunction-severity as well as trait scales and because it is based on the Clinical Description and Diagnostic Guidelines, which are more detailed than the “statistical” model description that is currently on the ICD-11 website. The authors wrote 992 items and then reduced the pool to 300 items by eliminating redundancy and selecting the consensus best few items for each subconstruct. Data were collected using an online sample of 383 Prolific workers. Using exploratory factor analysis, seven domain scales were developed, each of which contained two to four scales assessing components of the domain. These preliminary scales’ psychometrics were excellent, as were the domains’ and their components’ convergent and discriminant validity, with a few generally minor exceptions. Structural analyses at the component level revealed a three-factor structure consisting of two moderately correlated Internalizing factors, one centered on Self Dysfunction with two NA components and a DSN component and the other on Interpersonal Dysfunction with DET and ANK components; as well as an Externalizing factor with DSL and a DSN component that was uncorrelated with the other two factors. Two aspects of the results in particular are striking: ANK was not the opposite end of a DSN dimension, but rather contributed to an Internalizing Interpersonal Dysfunction dimension and DSN had both an Internalizing and an Externalizing component. Implications of the findings and study limitations are discussed. (shrink)

Rapid individual cognitive phenotyping holds the potential to revolutionize domains as wide‐ranging as personalized learning, employment practices, and precision psychiatry. Going beyond limitations imposed by traditional lab‐based experiments, new efforts have been underway toward greater ecological validity and participant diversity to capture the full range of individual differences in cognitive abilities and behaviors across the general population. Building on this, we developed Skill Lab, a novel game‐based tool that simultaneously assesses a broad suite of cognitive abilities while providing an engaging (...) narrative. Skill Lab consists of six mini‐games as well as 14 established cognitive ability tasks. Using a popular citizen science platform (N = 10,725), we conducted a comprehensive validation in the wild of a game‐based cognitive assessment suite. Based on the game and validation task data, we constructed reliable models to simultaneously predict eight cognitive abilities based on the users’ in‐game behavior. Follow‐up validation tests revealed that the models can discriminate nuances contained within each separate cognitive ability as well as capture a shared main factor of generalized cognitive ability. Our game‐based measures are five times faster to complete than the equivalent task‐based measures and replicate previous findings on the decline of certain cognitive abilities with age in our large cross‐sectional population sample (N = 6369). Taken together, our results demonstrate the feasibility of rapid in‐the‐wild systematic assessment of cognitive abilities as a promising first step toward population‐scale benchmarking and individualized mental health diagnostics.

The purpose of this study is to determine empirically the state of the art of the medical care, when healthcare personal is confronted with ethical dilemmas related with the care they give to the geriatric population. An observational, longitudinal, prospective and qualitative study was conducted by analyzing the correlation between healthcare personnel–patient relationship, and ethical judgments regarding dilemmas that arise in daily clinical practice with geriatric patients. Mexican healthcare personnel with current active practices were asked to write up an ethical (...) dilemma that arose frequently or that had impacted their medical practice. From the narrative input, we were able to draw up a database with 421 dilemmas, and those corresponding to patients 60 years and older were selected. The axiological analysis of the narrative dilemmas of geriatric patients was made using dialectical empiricism. The axiological analysis values found most frequently were classified into three groups: the impact of healthcare, the roles of the physician, and refusal of therapy; the healthcare role of educator, caring for the patients’ life and the risk of imminent death where the values found more often. The persistence and universality of certain dilemmas in geriatrics calls for awareness and requires a good training in the ethical discernment of these dilemmas. This would help to improve substantially the care and the life quality of this population. (shrink)

Se analizan los textos de Rafael Gutiérrez-Girardot sobre F. Nietzsche en torno a la tragedia y el pesimismo. Esta aproximación se elabora a partir de tres temas: estilo, nihilismo y estética. Se argumenta que la interpretación de Gutiérrez-Girardot sobre Nietzsche impide que este sea visto solo como un crítico literario. Asimismo, este trabajo brinda el tono a la escritura de Rafael Gutiérrez Girardot y, de este modo, configura su estilo personal.

Este artículo examina la concepción racionalde Hare sobre los juicios morales.Para ello, critica tajantemente la concepcióne mo t i v i s t a de l o s Po s i t i v i s t a s l ó g i c o s yde St e ve ns on. Tambi é n, s e di s t anc i a de lintuicionismo moral concebido por Moore ensus Principia Ethica de 1903. Para desarrollarel racionalismo moral parte del principio (...) queel lenguaje moral hace parte del lenguaje engeneral, del cual no puede ser desligado puescuando hacemos razonamientos morales estosse encuentran sometidos por las diferentesreglas de la lógica clásica. Por ello, Hare aplicala lógica clásica a su teoría de los imperativosy considera la ética como el estudio lógico dellenguaje moral.También se muestran las semej anzas y lasdiferencias entre la concepción de Austin y deHare, destacando la evolución del pensamientode este último filósofo. Cuando Hare escribiósu obra El Lenguaje de la Moral no estabai nf l uenci ado por l a t r i cot omí a de Aust i nsobre Los actos de habla como: Locucionarios,ilocucionarios y perlocucionarios. Influenciaq u e s e o b s e r v a e n e s c r i t o s p o s t e r i o r e s .Mi e nt r a s Ha r e ubi c a l os j ui c i os mor a l e sen l o l ocuci onari o, Austi n l os ubi ca en l oilocucionario; controversia que nos conducea r e f l e xi ona r s obr e l a i mpor t a nc i a de l apragmática en los juicios morales y a la vezsobre su racionalidad.I n t hi s pa pe r , I e xa mi ne Ha r e ’ s r a t i ona lconception on moral judgements. For this, hecriticizes sharply the emotivist conception ofLogical Positivists and of Stevenson. He alsoaparts himself from Moore’s moral intuitionism,as expounded in Principia Ethica. To developmoral rationalism, Hare starts from the principlethat moral language is apart of the generallanguage, from which it cannot be separatedsince when we do moral reasonings these areruled by the different rules of classical logic.For this reason, Hare applies classical logic tohis theory of imperatives and considers ethicsas the logical study of moral language.I also show the similarities and differencesbetween Austi n’ s and Hare’ s concepti ons,emphasizing the evolution of the thought of thelater. When Hare wrote The language of morals,he was not under the influence of Austin’stricotomic view of speech acts: locutionary,illocutionary and perlocutionary, influence thatwe can see in later works. While Hare locatesmoral judgments in the locutionary, Austin doesit in the illocutionary. This controversy leadsus to think on the importance of pragmatics inmoral judgements as well as on its rationality. (shrink)

ABSTRACT In the Science of Logic, Hegel analyzes Kant's two mathematical antinomies; carries out an internal critique of their proof; and concludes that they are mere examples of petitio principii. Nevertheless, he recognizes the legitimacy of Kant's discovery. The article analyzes how these two approaches come together and complement each other. The purpose of this analysis is to show how Hegel takes the antinomy of pure reason back to its conceptual foundation, thus stripping it of all empirical content and dissolving it through a critique of Kant's formulation.

En un artículo anterior expusimos el marco cristológico donde trata la Escolástica la ciencia humana de Jesucristo. Al asumir el Verbo la naturaleza humana de Jesús para llevar a cabo la redención, implica la consideración de la constitución ontológica del Hijo de Dios. Esto se analiza en la cuestión de la unión hipostática. La postura de la Escuela Franciscana arranca de Alejandro de Hales ante las tres opiniones que Pedro Lombardo transmite en las Sentencias. Por otra parte, esta cuestión (...) conduce al análisis de la esencia y propiedades de dicha naturaleza asumida. Con esto se contemplan, no sólo las cualidades naturales, por lo general situadas en el alma de Cristo, sino también los defectos aducidos en el estudio sobre la pasión y muerte de Cristo, centro de la aislada soteriología medieval.

En el siguiente estudio se evalúa un panorama con respecto al comportamiento sociológico en un preámbulo tanto antes durante y después de esta crisis social que se está viviendo debido a la pandemia de hoy en día. Por ello para sustentar dicha investigación se realizó un censo en el cuál, mediante el uso de herramientas estadísticas, se pudo realizar una comparación entre un antes y un durante de la pandemia, lo cual facilitaría intrínsicamente a la predicción de una denominada post (...) pandemia. En este texto se pretende detallar el proceso y forma de la encuesta, al igual que los resultados obtenidos de la misma. Se proveen, además, posibles explicaciones para estos resultados, guiándose por las restricciones de salud nacionales como posibles razones para el cambio de comportamiento actual.
