Probability plays a crucial role regarding the understanding of the relationship which exists between mathematics and physics. It will be the point of departure of this brief reflection concerning this subject, as well as about the placement of Poincaré’s thought in the scenario offered by some contemporary perspectives.

¿De qué hablamos cuando decimos Diseño Sustentable? El diseño sustentable podría definirse como el diseño que tiene en cuenta los aspectos ambientales en todos los niveles de producción. Así mismo, persigue el objetivo de fabricar productos que aporten el menor impacto posible en el ecosistema a lo largo de todo el ciclo de vida. Es muy difícil encontrar productos de consumo que cumplan puntualmente con los Preceptos del eco diseño y que sean exitosos en el mercado. Ante esta situación es (...) necesario revisar los aspectos involucrados en la concepción de un nuevo producto: ¿El rol del diseñador es el adecuado?, ¿Existe una seria y responsable conciencia por parte de los empresarios para llevar adelante un proyecto de eco diseño?, ¿Son los productos eco lo suficientemente atractivos para captar la atención de los consumidores?

This article addresses the new theories and concepts of design management: design thinking, user experience (UX) and service design. They consider people's experiences and focus on the characteristics of each one of them. From industrial design, the scope and relationships between these definitions - now better visible - were analyzed, which always belonged to the design field of the discipline, from which an attempt was made to identify how they influence innovation, design and development of new products. To account for (...) the evolution that the design field has had, the most significant processes are contrasted to visualize the differences that make this change fundamental. Finally, it is concluded on its strategic relevance for the application in public and private organizations. Also taking into account how these theories are methodologically incorporated into the set of activities inherent to industrial design. (shrink)

Purpose: The research explored empirical evidence to assess the impact of cyber security and supply chain risk on digital operations in the UAE pharmaceutical industry. Methodology/Design/Approach: Based on responses from 243 personnel working at 14 pharmaceutical manufacturing companies in Dubai, data were examined for normality, instrument validity and regression analysis. Cyber security and SC risk on digital operations were explored by applying convenient sampling and descriptive and analytical research design. Findings: The findings validated the significant positive association between cyber security (...) and supply chain risk with digital operations. Research implications and Limitations: The research model was developed with three variables evaluated only on the pharmaceutical industry in Dubai. Future research should focus on multiple manufacturing industries by covering a larger geographic area. Practical implications: When suppliers are highly concentrated, customer-focused organisations with uncertain levels of digital transformation could improve their ability to manage supply chain risk by diversifying their clients. Pharmaceutical firms may require a greater focus on technology-based manufacturing firms to build and maintain customer trust. Originality Value: To illustrate how the pharmaceutical industry has explored the relationship between cyber security, supply chain risk and digital operations, the research highlights the significant and convoluted consequences of the relationship model that have not been previously considered.

This article attempts to open the debate on a territorial development perspective that fixes the interest in organized territories that are characterized by the existence of a community with a local identity, politically and administratively regulated. We conceive these territories as subjects of development promotion interventions. For this we propose a model for the creation of Municipal Development Forums, which with the participation of local actors, can generate a tailor-made Local Development Program. The development program will consider a diagnosis of (...) the productive profile of the territory and its relationship with the characteristics and origin of goods or services consumed at the municipality. Based on the diagnosis, the causes of the decoupling between the local production system and consumption needs can be detected. And with this, find a way to readjust local production systems to meet the demand for goods and services of the inhabitants, generating new companies and encouraging local consumption. (shrink)

The objective of this article is to analyze the relationships between theories of strategic design and participatory design, in multiple commercial alliances between local entrepreneurs from different sectors and their integrated application in the urban context. Various authors have dealt with these strategic issues in isolation and less frequently have addressed them from the entrepreneurial experience. A review of the specific literature allows us to account for the main concepts involved in this approach. The case being analyzed refers to a (...) fitness-related venture in the city of La Plata, which articulated, together with other local actors, a collaborative strategy that led to the application of a superior business model for its sector. In addition, he capitalized on his role as an influencer on the social network Instagram, as a way to enhance the project’s comprehensiveness. The topics that are addressed synthesize the key concepts that allow us to interpret the praxis relieved. And from them, create a model that can be applied in other markets and territories to promote young local development. And in this way, different actors, complementary products and services serve to jointly promote a co-productive and self-managed culture. (shrink)

This work aims to study strategies used in Argentine local development experiences, focussing on industrial design, marketing and entrepreneurship. In order to this purpose, backgrounds are analysed with this approach adding the study of three strategic plans for national and provincial-level that are currently in force. With the analysis of the transport system in the last decade, an accelerated cost increase is evident, resulting in a relatively higher price of distributed products. This situation that was initially perceived as a disadvantage (...) finally set up an opportunity to produce locally. The goal of this paper is to provide tools that contribute to the work shipped by key institutions for local development (public, private and intermediary organisations), and the way these interact with the actors and the territory. In particular, the identification of productive sectors and the selection of goods that can be produced and consumed locally, as a key input for the formulation of projects. (shrink)

The study, design and development of a low-cost digital braille printer is boarded with a transdisciplinary approach. The main challenge was focused on reducing significantly the high cost of this type of printers and their printing services. This context is aggravated with the low commercialization of these products in the country, a factor that makes the access of these tools -that are essential to much of the low and middle sectors of the Argentine social structure- even more difficult. An interdisciplinary (...) group of teachers, graduates and students of the careers of industrial design and informatics degree from the National University of La Plata, developed the design and prototype of a braille printer. The work was carried out according to the principles of Gandhian Engineering, based on the reuse of ink-jet printers. The project consists of the design, development and generation of a low-cost Braille printer, produced locally, which prioritizes the use of nationally manufactured components for assembly. To achieve this, an electronic and electromechanical system was designed and manufactured to adapt any Inkjet printer to the objectives of the project, enabling the recycling of obsolete printers. This means, it is proposed to resolve through the use of text printers, applying technical knowledge of computer science and industrial design, to adapt the technological components to the Braille lexicon printer. They also developed, on the one hand, software that controls the printer and allows its use in a simple and accessible way. On the other hand, the hardware and external components were adapted with 3D printing technology and thermoforming, producing a housing that contains the entire printer. Finally, a systematization of the assembly process of the printer prototype was carried out, making it possible to replicate it. Using methodologies of Gandhian Design, a prototype and two alternative proposals of carcasses were obtained. The main objective, which guided this work, was that blind people can access low-cost braille printers promoting by this a favorable impact on the cultural development of their daily lives. (shrink)

Often, there are conceptual differences between politicians, officials, academics and professionals on key concepts related to forms of administrative organization of the State and in relation to the categorization of the various subjects who directs their actions. Settle these differences contribute to the implementation of the modernization of the State.

This paper attempts to open the debate on the idea of local and territorial development of microregional nodes in the Province of Buenos Aires. Under this approach, a model that proposes the creation of Municipal Development Forum, with the participation of local actors, generate local development program is proposed. The proposal is formulated for territories over 5,000 and below 30,000 inhabitants. This criterion is based on the applicability of the proposed model to municipalities with potential for territorial development, large and (...) balanced internal consumption, but where progress is hindered by the proximity of one or two political jurisdictions of a larger productive scale that have became regional administrative centers. The development program will consider a diagnosis of the productive profile of the territory and its relationship with the characteristics and origin of goods or services consumed at the municipality. This territorial development model aims to move towards self-sufficiency on goods and services, to create new jobs and to promote effective and efficient use of local resources. In short, we propose to tackle territorial development from an innovative perspective, focusing on the creation of Municipal Development Fora that foster the improvement and growth of the productive system, the creation of jobs, local identity and the consumption of goods and services locally produced.

Il design industriale è sempre più importante come mezzo per differenziare i prodotti e aumentarne il valore. Allo stesso tempo, la velocità con cui un prodotto viene offerto nel mercato dipende dalla capacità di integrare il design nel processo di produzione. Tuttavia, molte PMI - in particolare le nuove aziende basate sulla tecnologia - mancano di competenze specialistiche nella gestione del design e spesso non prestano sufficiente attenzione a questo aspetto. L'industria automobilistica e le grandi aziende come Philips e Braun (...) gestiscono e misurano l'impatto del design come strumento innovativo. Negli ultimi anni, le aziende industriali che sono in prima linea nella produzione di determinati prodotti stanno iniziando a sperimentare una forte concorrenza che non è egualmente protetta. Subiscono gli impatti dell'esperienza offerta da quasi gli stessi prodotti a prezzi inferiori, grazie a un minore investimento in ricerca e sviluppo, che riduce la struttura dei costi. (shrink)

Objective of the study: To analyze the costs and profits of sugarcane production regarding the cultural practices of sugarcane suppliers. Methodology/approach: This study positions itself in this gap by comparatively analyzing 6 types of cultural practices: unraveling, windrowing, application of correctives, herbicides, insecticides and fertilizers, with the option of two systems Fixed rate (TF) and Variable rate (TV). Originality/Relevance: Brazil is a world reference in sugarcane production, with the State of São Paulo being the largest Brazilian producer. However, for sugarcane (...) suppliers to maintain this activity there is a need to reduce production costs and increase profitability/ha. However, there is a theoretical-practical gap in the financial assessment (costs and profits) of different cultural practices inherent to sugarcane production. Main results: The results demonstrated that the costs of cultural practices represent more than 30% of the total sugarcane production costs. The TF system proved to be more cost-efficient in the following operations: correctives, herbicides and insecticides. In the application of fertilizers, the TV system, in broadcast mode, had the best result. Finally, the profit/ton was R$1.70, demonstrating a very low profit margin/ha given the risk of the activity. Theoretical/methodological contributions: The sample for this research comprised 55 sugarcane suppliers from the State of São Paulo, whose data were obtained through a survey. The comparative analysis was based on the difference in costs of cultural practices and the estimation of the level of certainty (profit/costs), analyzed through the cumulative frequency carried out through the Monte Carlo Simulation (SMC).

In the remainder of this article, we will disarm an important motivation for epistemic contextualism and interest-relative invariantism. We will accomplish this by presenting a stringent test of whether there is a stakes effect on ordinary knowledge ascription. Having shown that, even on a stringent way of testing, stakes fail to impact ordinary knowledge ascription, we will conclude that we should take another look at classical invariantism. Here is how we will proceed. Section 1 lays out some limitations of previous (...) research on stakes. Section 2 presents our study and concludes that there is little evidence for a substantial stakes effect. Section 3 responds to objections. The conclusion clears the way for classical invariantism.

Does the Ship of Theseus present a genuine puzzle about persistence due to conflicting intuitions based on “continuity of form” and “continuity of matter” pulling in opposite directions? Philosophers are divided. Some claim that it presents a genuine puzzle but disagree over whether there is a solution. Others claim that there is no puzzle at all since the case has an obvious solution. To assess these proposals, we conducted a cross-cultural study involving nearly 3,000 people across twenty-two countries, speaking eighteen (...) different languages. Our results speak against the proposal that there is no puzzle at all and against the proposal that there is a puzzle but one that has no solution. Our results suggest that there are two criteria—“continuity of form” and “continuity of matter”— that constitute our concept of persistence and these two criteria receive different weightings in settling matters concerning persistence.

In epoca medievale si è molto discusso su alcuni concetti chiave come prova o giustificazione. La teoria della prova contenuta nei trattati di logica medievale prende il nome tecnico di consequentia, che è un tipo di ragionamento fondato sul passaggio dalla concessione (o negazione) di uno o più enunciati denominati antecedenti alla concessione (o negazione) di uno o più enunciati denominati conseguenti. Questo tipo di teoria ha avuto un correlato a livello dei singoli termini che compongono l’enunciato all'interno della teoria (...) nota come suppositio terminorum. Prende, infatti, il nome di descensus, la regola che permette la verifica del passaggio da un termine maggiore (un termine comune) ad un termine minore (che denota individui). La stessa definizione di alcune ramificazioni della teoria della suppositio è col-legata alla possibilità di ammettere o meno il descensus cioè questa "discesa" da un termine comune ad una congiunzione o disgiunzione di termini singolari. Il presente lavoro intende descrivere la teoria del descensus come un tipo particolare di consequentia mostrandone le connessioni con le moderne tecniche logiche. I trattati che si affronteranno appartengono al XIV e al XV secolo, cioè ad un periodo caratterizzato da una sistemazione della materia che li rende confrontabili con un quadro teorico unitario.

Darwin’s claim that Natural Selection, through optimization of fitness, explains complex biological design has not yet been properly formalized. Alan Grafen’s Formal Darwinism Project aims at providing such a formalization and at demonstrating that fitness maximization is coherent with results from Population Genetics, usually interpreted as denying it. We suggest that Grafen’s proposal suffers from some limitations linked to its concept of design as optimized fitness. In order to overcome these limitations, we propose a classification of evolutionary facts based on (...) a bi-dimensional complexity space, which adds robustness to fitness as measure of the quality of a design. In this space, each point represents an organismic architecture, and movement between two points would be an evolutionary fact. Natural Selection explains movement along the fitness axis, while non-selective mechanisms explain movement on the robustness axis. Moreover, we propose a thermodynamic metaphor to draw parallelisms between notions of fitness and entropy, robustness and energy, and movement in this space and reversible and irreversible cycles. We argue that this metaphor illustrates different evolutionary processes usually overlooked by proposals of formalization of Darwinian theory, such Grafen’s Formal Darwinism Project. (shrink)

The costs of agricultural inputs added to those of labor represent almost a third of the total cost of Brazilian sugarcane production. This study analyzes the behavior of the price per ton of sugarcane in Brazil, relating it to the main production costs of this cultivation. Twelve price indicators from January 2015 to December 2020 were evaluated. First, the data were adjusted to a multiple linear regression model to identify the significant variables on variation in the price per ton of (...) sugarcane. Then, the Monte Carlo simulation was used to measure the level of certainty of occurrence of these variables, and forecasts were obtained from the adjustment of ARIMA models. The results showed the influence of the costs of diesel oil, two agricultural pesticides, and daily laborers on the price of sugarcane, besides an increasing trend of its, providing relevant short-term projections for decision-making about investments in the agribusiness sector.

The diversity in agronomic practices being used by sugarcane producers in Brazil determines differences in economic performance and cost structure. The purpose of this study is to evaluate the cost of six systems of agronomic practices using fixed or variable rates for soil amendment, fertilizer, and defensive applications and assess the profitability of these systems at three scales of sugarcane production. We then describe the data sample related to the 2019–2020 harvest season and collected from fifty-five sugarcane producers in the (...) central-south region of Brazil. Thereafter, using a quantitative approach, a cost analysis was performed, and the cumulative frequency of the net revenue for the three scales of production (small, medium, and large), was calculated using a Monte Carlo simulation. The cost analysis indicated that fertilizer had the highest cost considering the agronomic practices adopted at the three scales of production analyzed. The cumulative frequency analysis results from the Monte Carlo simulation showed the highest net revenue per hectare for medium sugarcane producers. In addition, the presence of economies of scale was not confirmed because the lowest cost was found in small-scale sugarcane producers and the highest net revenue was obtained by medium-scale sugarcane producers.

Los conceptos de evolución y cambio evolutivo son a la vez laxos y polisémicos: se aplican a fenómenos muy diferentes y no siempre se definen con precisión. La aplicación extendida del paradigma neo-darwinista clásico, además, suele imponer un esquema adaptacionista al análisis de los hechos evolutivos, en el cual las funciones juegan un papel lógicamente anterior a los rasgos y sus formas. En este artículo proponemos, como etapa previa a la formulación de hipótesis sobre las causas del cambio, un modelo (...) de espacio forma-función que pueda responder a preguntas como cuándo se da un cambio en los rasgos de una arquitectura biológica y de qué tipo son estos cambios. Un modelo de este tipo nos permite ver claramente cuándo se da un cambio en la forma o en la función y qué alcance evolutivo tiene. (shrink)

L’osservazione della natura con l’intento di capire l’origine della varietà di forme e fenomeni in cui si manifesta ha origini remote. All’inizio il rapporto con i fenomeni naturali era dominato da sentimenti quali paura e stupore che conducevano a supporre l’esistenza di entità sfuggenti alla percezione diretta che permeavano gli elementi animandoli. Ecco dunque che la magia rappresenta l’elemento dominante della filosofia naturale primitiva caratterizzata da una unicità degli eventi e dalla impossibilità di capirli e dominarli in quanto frutto della (...) volontà di essenze a noi estranee e non governabili. Con il nascere della civiltà ed il suo progredire il tempo dedicato ai lavori necessari per il sostentamento e la sopravvivenza diminuì e nella ripartizione dei compiti alcuni individui potevano dedicare parte del loro tempo alla osservazione della natura ed alla sua interpretazione in termini non trascendenti. Nella natura, intesa come tutto ciò che ci circonda composto da esseri viventi e da materia inorganica nelle sua varie aggregazioni sulla terra e nel cosmo, ciò che attirò l’attenzione fin dall’inizio furono furono i fenomeni regolari e periodici come i moti della luna, dei pianeti e delle stelle. Nel contempo dopo una spinta iniziale dettata da esigenze pratiche come contare gli oggetti o misurare i campi, la matematica si era sviluppata autonomamente e si rivelò idonea a descrivere in termini quantitativi i moti dei corpi celesti. La terra era al centro dell’universo mentre il moto degli altri corpi celesti risultava da una composizione di moti circolari uniformi. Questa visione geocentrica e pitagorica (armonia delle sfere) dell’universo ha prevalso fino agli albori della scienza moderna, anche se una descrizione eliocentrica, basata su validi argomenti, era stata proposta. Per quanto riguarda la struttura della materia i presocratici avevano già proposto i quattro elementi mentre gli atomisti avevano ricondotto tutto ad entità elementari primigenie, il cui aggregarsi e disgregarsi da luogo a tutti gli stati e le molteplici forme della materia. Queste intuizioni si ritrovano nella fisica moderna che contempla quattro stati di aggregazione, che hanno come unico sostrato comune gli atomi. La fisica moderna nasce con Galileo e Newton, la cui dinamica si sviluppa a partire dalle leggi di Keplero che descrivono il moto dei pianeti nel sistema eliocentrico, per potersi poi applicare ad un qualunque sistema materiale. Pertanto nei due secoli successivi si ritenne che un modello meccanico potesse essere sviluppato per un qualunque sistema fisico e quindi per l’universo intero la cui evoluzione doveva essere matematicamente prevedibile. Per i fenomeni termici tuttavia vennero formulate leggi ad hoc come quelle della termodinamica che mostrano come i processi macroscopici siano irreversibili in contrasto con le leggi della meccanica. Si deve a Boltzmann1 il tentativo di ricondurre la termodinamica alla meccanica per un gran numero di particelle dei cui moti disordinati viene data una lettura di carattere statistico. L’aumento della entropia e la irreversibilità seguono dalla ipotesi di caos molecolare ossia che i moti siano così disordinati che si perde rapidamente memoria dello stato iniziale. L’idea di introdurre una misura di probabilità nel contesto della meccanica sembra antitetica con la natura stessa della teoria rivolta fino ad allora allo studio di sistemi con moti regolari, reversibili e prevedibili individualmente su tempi lunghi. Tuttavia l’analisi probabilistica diventa essenziale per lo studio di sistemi caratterizzati da forti instabilità, e da orbite irregolari per i quali la previsione richiede una conoscenza della condizioni iniziali con precisioni fisicamente non raggiungibili. Combinando la evoluzione deterministica della meccanica di Newton o di Hamilton con la descrizione statistica attraverso una opportuna misura invariante di probabilità nello spazio delle fasi, nasce la teoria dei sistemi dinamici2 che consente di descrivere non solo i sistemi ordinati o i sistemi caotici ma anche tutti quelli che vedono coesistere in diverse proporzioni ordine e caos e che presentano una straordinaria varietà di strutture geometriche e proprietà statistiche, tanto da fornire almeno se non proprio un quadro teorico per lo meno metafore utili per la descrizione dei sistemi complessi. Anche se non c’è unanime consenso ci sembra appropriato definire complessi non tanto sistemi caratterizzati da interazioni non lineari tra i suoi componenti e da proprietà emergenti, che rientrano a pieno titolo nel quadro dei sistemi dinamici, ma piuttosto i sistemi viventi o quelli di vita artificiale che ne condividono le proprietà essenziali3. Tra queste possiamo certamente annoverare la capacità di gestire la informazione e di replicarsi, consentendo tramite un meccanismo di mutazione e selezione di dare origine a strutture di crescente ricchezza strutturale e dotate di capacità cognitive sempre più elaborate. Una teoria dei sistemi complessi non esiste ancora, anche se la teoria degli automi sviluppata da Von Neumann4 e la teoria della evoluzione di Darwin5 ne possono fornire alcuni pilastri importanti. Recentemente la teoria delle reti è stata utilizzata con successo per descrivere le proprietà statistiche delle connessioni tra gli elementi costitutivi (nodi) di un sistema complesso6. Le connessioni che non sono né completamente casuali né completamente gerarchiche, consentono una sufficiente robustezza rispetto a malfunzionamenti o danneggiamenti dei nodi unita a un adeguato livello di organizzazione per consentirne un funzionamento efficiente. Nei sistemi fisici il modello base è un insieme di atomi o molecole interagenti, che danno luogo a strutture diverse quali un gas, un liquido o un cristallo, come risultato di proprietà emergenti. Nello stesso modo per i sistemi complessi possiamo proporre un sistema automi interagenti come modello base. Le molteplici forme che il sistema assume anche in questo caso vanno considerate come proprietà emergenti del medesimo sostrato al mutare delle condizioni esterne e frutto delle i replicazioni, ciascuna delle quali introduce piccole ma significative varianti. Questa è la grande differenza tra un sistema fisico ed un sistema complesso: il primo fissate le condizioni esterne ha sempre le medesime proprietà, il secondo invece cambia con il fluire del tempo perché la sua organizzazione interna muta non solo al cambiare di fattori ambientali ma anche con il succedersi delle generazioni. C’è dunque un flusso di informazione che cresce con il tempo e che consente agli automi costituenti ed alla intera struttura di acquisire nuove capacità. Questo aumento di ordine e ricchezza strutturale avviene naturalmente a spese dell’ambiente circostante, in modo che globalmente i la sua entropia cresce in accordo con la seconda legge della termodinamica. In assenza di una teoria formalizzata paragonabile a quella dei sistemi dinamici, per i sistemi complessi si possono fare osservazioni e misure, sia puntuali sui costituenti elementari e sulle loro connessioni, sia globali sull’intero sistema, oppure costruire modelli suscettibili di essere validati attraverso la simulazione. Se di un sistema si riesce infatti a fornire una descrizione sufficientemente dettagliata, è poi possibile osservare come questo si comporti traducendo le regole in algoritmi e costruendo quindi una versione virtuale, anche se semplificata del sistema stesso. Il passaggio più difficile è il confronto tra il sistema simulato ed il sistema vero, che passa necessariamente attraverso la valutazione di una numero limitato di parametri che ne caratterizzino e proprietà. La codifica del progetto è una proprietà cruciale dei sistemi complessi perché questa si realizza con un dispendio di massa ed energia incomparabilmente più piccolo rispetto a quello necessario per realizzare l’intera struttura; nello stesso tempo apportare piccole modifiche ad un progetto è rapido ed economico. In questo processo che comporta la continua introduzione di varianti si aprono molteplici strade e con lo scorrere del tempo si realizza una storia in modo unico e irripetibile. Anche il susseguirsi di eventi fisici caratterizzati da processi irreversibili e dalla presenza di molteplici biforcazioni da origine ad una storia che non si può percorrere a ritroso, né riprodurre qualora fossimo in grado ripartire dalle stesse condizioni iniziali. Tuttavia esiste una differenza profonda tra la storia di un sistema fisico come il globo terrestre e la storia della vita. La prima registra i molteplici cambiamenti che ha subito la superficie del nostro pianeta ove montagne e mari nascono e scompaiono senza un chiaro disegno soggiacente. La storia della vita è caratterizzata da una progressiva crescita della ricchezza strutturale e funzionale e accompagnata da una crescita della complessità progettuale. La rappresentazione di questa storia prende la forma di un albero con le sue ramificazioni che mostra la continua diversificazione delle strutture e la loro evoluzione verso forme sempre più avanzate. La direzione in cui scorre il tempo è ben definita: le strutture affinano le capacità sensoriali mentre cresce la potenza degli organi che elaborano la informazione. Un sistema complesso è anche caratterizzato da un molteplicità di scale, tanto più alta quanto più si sale sulla scala evolutiva. La ragione è che il procedere verso strutture sempre più elaborate avviene utilizzando altre strutture come mattoni per cui l’immagine che si può fornire è quella di una rete di automi a più strati: partendo dal basso una rete con le sue proprietà emergenti diventa il nodo di una rete di secondo livello, cioè un automa di secondo livello che interagisce con altri automi dello stesso tipo e così via. Nei sistemi inorganici, dove non esiste un progetto, si distinguono di norma solo due livelli, quello dei costituenti elementari e quello su scala macroscopica. I sistemi fisici sono riconducibili a poche leggi universali, che governano i costituenti elementari della materia, ma il passaggio dalla descrizione dalla piccola alla grande scala è impervio e consentito soltanto dalla simulazione numerica, quando ci allontaniamo dalle situazioni più semplici caratterizzate da un equilibrio statistico. I limiti che il disegno riduzionista incontra già per i sistemi fisici diventano decisamente più forti nel caso dei sistemi complessi. (shrink)

Seguramente lo más interesante de la suspensión de la cuenta de Twitter del ya expresidente Trump después del asalto al Capitolio no sea el debate tan manido sobre los límites de la libertad de expresión, sino el hecho mucho más significativo de que hoy es Twitter quien decide sobre el estado de excepción. Para desentrañar esta particular relación entre técnica y estado de excepción tan característica de nuestro predicamento contemporáneo, hay que leer a Giorgio Agamben. En este sentido, el (...) libro de Juan Evaristo Valls Boix, Política sin obra, ofrece una introducción tan divulgativa como profunda al trabajo del filósofo político italiano. Este ejemplar se enmarca dentro de la colección Pensamiento político posfundacional de la Editorial Gedisa, que lleva desempeñando, en los últimos años, una labor pedagógica admirable a la hora de dar a conocer al público, en lengua castellana y catalana, los principales filósofos y filósofas de lo político que han problematizado cualquier tipo de fundacionalismo –Lyotard, Foucault, Arendt, Derrida, Lefort, Laclau, Mouffe, Badiou, Rancière, Butler, Nancy, Abensour y Anzaldúa, entre otros y otras–. Cuando llega el turno de introducir a Agamben, la directora de la colección, Laura Llevadot, ya avisa que se trata de una auténtica “introducción a la vida no fascista”, haciendo un guiño al prólogo de Foucault sobre el Anti-Edipo de Deleuze y Guattari.

Who is Pulcinella? What does his laughter have to say about the "end of time" and the end of life of Giandomenico Tiepolo? How can the end of a life make anyone laugh like Carnival’s popular mask does? This article tries to answer such questions. By unfolding the tools that come from the realm of Giorgio Agamben’s philosophy – notably the notion of "recapitulation of time" in its relation to comedy – we will trace a path which links Michail (...) Bachtin’s theories on the carnivalesque culture together with a recognition in the aesthetics of "character". In this encounter, the consistency of Pulcinella-King Carnival’s form of life will appear in the light of an “escape route”: it winks at a kind of general and anonymous beatitude, which pairs with the experience of the destitution of time.

The analysis of the moral doctrines contained in the Moralis philosophia of Roger Bacon reveals the central place reserved to the vice of anger. Bacon considers it a very serious sin, which goes against the human nature and makes many devastating effects on individuals and their social relations. Bacon’s moral doctrines are based on a source that has been recently rediscovered, Seneca’s De ira. Bacon is one of the first authors to quote extensively that work. Bacon’s enthusiasm for the Latin (...) philosopher is the result of his conviction of the superiority of pagan philosophers over the Christians, especially in the field of ethics. The knowledge of the ancients, which is necessary for the life of individuals and for the proper function of institutions, is a duty for Christian thinkers. (shrink)

Este artículo analiza la cosmovisión del narrador de La ciudad y los perros en función del efecto catártico, caracterizado por conseguir la identificación con los personajes o los escenarios representados en el texto. Para obtener esa sensibilidad anhelada en el lector, es imprescindible el conocimiento de los mecanismos que conllevan la asociación de patrones afines. Por ello, se recurrirá a conceptos de Mario Perniola, Slavoj Žižek, entre otros, para determinar el desarrollo de ese proyecto de lectura idealizada. Considerando esa posibilidad, (...) se asume que durante ese proceso está presente la asimilación y el rechazo de información; es más, se erige una actitud crítica y hasta una repulsión por actos antiéticos (la violencia). Igual ocurrirá con respecto al planteamiento de la representación de la historia en la novela como trama, debido a que el lector requiere una secuencia lógica que pueda comprender (hilvanará secuencias lógicas, a pesar de que estas se muestren técnicamente dispersas o confusas); por ese motivo, la exigencia en función de su atención y su captación será necesaria (así se podrá negar o aceptar una propuesta exhibida, cuestionarla u obviarla).

Mereological universalists, according to whom every plurality of entities has a fusion, usually claim that most quantifications are restricted to ordinary entities. However, there is no evidence that our usual quantifications over ordinary objects are restricted. In this article I explore an alternative way of reconciling Mereological Universalism with our usual quantifications. I resort to a modest form of ontological expansionism and to the so-called interpretational modalities. Quantifications over ordinary objects are the initial stages of the expansion. From these initial (...) stages, expansions can proceed upwards (fusions of entities in the domain of quantification are added), downwards (parts of entities in the domain are added), and sidewards (entities which are mereologically disjoint from the entities in the domain are added). These expansions are driven by a variety of epistemic and pragmatic reasons and raise different kinds of problems. At each stage, a modalized version of Mereological Universalism is true. By contrast, only at some especially rich stages, standard, non-modalized Mereological Universalism is true as well. Among these especially rich stages, there is a final, metaphysically pre-eminent stage of mereological plenitude. In the last part of the article I discuss some problems and limitations of expansionism. (shrink)

This book presents a comprehensive theoretical framework that explains both human consciousness and meanings through the working of attention. By arguing for a first-person approach to consciousness, this book offers a critical overview of the major theories and empirical findings on consciousness and attention, and exemplifies how one of the most difficult and fundamental conscious experiences to account for, that is, time, can be analyzed by adopting the kind of semantics developed within the presented theoretical framework: Attentional Semantics.

The present work outlines a logical and philosophical conception of propositions in relation to a group of puzzles that arise by quantifying over them: the Russell-Myhill paradox, the Prior-Kaplan paradox, and Prior's Theorem. I begin by motivating an interpretation of Russell-Myhill as depending on aboutness, which constrains the notion of propositional identity. I discuss two formalizations of of the paradox, showing that it does not depend on the syntax of propositional variables. I then extend to propositions a modal predicative response (...) to the paradoxes articulated by an abstraction principle for propositions. On this conception, propositions are “shadows” of the sentences that express them. Modal operators are used to uncover the implicit relation of dependence that characterizes propositions that are about propositions. The benefits of this approach are shown by application to other intensional puzzles. The resulting view is an alternative to the plenitudinous metaphysics of impredicative comprehension principles.

Some arguments against the assumption that ordinary people may share common knowledge are sound. The apparent cost of such arguments is the rejection of scientific theories that appeal to common knowledge. My proposal is to accept the arguments without rejecting the theories. On my proposal, common knowledge is shared by ideally rational people, who are not just mathematically simple versions of ordinary people. They are qualitatively different from us, and theorizing about them does not lead to predictions about our behavior. (...) Nevertheless, models of action that assume common knowledge have a role to play in our understanding of collective rationality. (shrink)

According to the Maxim of Quality, rational agents tend to speak honestly. Due to the influence of Grice, a connection between linguistic rationality and honesty is often taken for granted. However, the connection is not obvious: structural rationality in language use does not require honesty, any more than it requires dishonesty. In particular, Quality does not follow from the Cooperative Principle and structural rationality. But then what is honest rational speech? I propose to move the discussion in the context of (...) Stalnaker's theory of assertion. From this perspective, although there is no most rational way to behave, Quality follows from the structure of Stalnakerian conversations if interlocutors are sensitive to credibility. In this case, honesty is built on the expectation of reciprocity, and cooperativity is an outcome and not a precondition of rational communication. A benefit of my discussion is that the account of linguistic rationality falls under the more general view of interactive rationality familiar from theoretical economics. (shrink)

I argue that it is not acceptable to restrict the claim that linguistic types are concrete entities (type-concretism) to some categories of linguistic types (such as words or proper names), while at the same time conceding that other categories of linguistic types (such as sentence types) are abstract entities. Moreover, I suggest a way in which type-concretism can be extended to every linguistic type, thereby responding to the so-called productivity objection to type-concretism, according to which, whenever tokens of a type (...) t are produced in different, causally isolated circumstances, then t needs to be identified by a certain form or structure. This extension of type-concretism detaches type-concretism from so-called originalism and gives rules a prominent role in type-concretism. (shrink)

Este artículo extrapola conceptos cinematográficos que desarrollan Gilles Deleuze y Alain Badiou, tales como movimiento, cuadro, plano y montaje. El propósito de corroborar estas categorías es para articularlas en el largometraje del director Melinton Eusebio, Jarjacha. El demonio del incesto (2000), y detectar la cosmovisión concomitante que prevalece en una localidad distanciada de la capital, caracterizada por la presencia andina de una tradición y una organización política basada en el sometimiento de una localidad hacia un alcalde, quien dictamina y castiga (...) a través de una personificación endemoniada. Este análisis será factible, una vez que se diferencien los instantes privilegiados y ordinarios, que abarcan las escenas de la película de acuerdo con su intencionalidad. De ese modo, se comprenderá el funcionamiento del filme desde una perspectiva más contundente y eximia para el espectador, además de que logrará reconocer los momentos fundados desde la realidad y lo real.

David Kaplan famously argued that mainstream semantics for modal logic, which identifies propositions with sets of possible worlds, is affected by a cardinality paradox. Takashi Yagisawa showed that a variant of the same paradox arises when standard possible worlds semantics is extended with impossible worlds to deliver a hyperintensional account of propositions. After introducing the problem, we discuss two general approaches to a possible solution: giving up on sets and giving up on worlds, either in the background semantic framework or (...) in the corresponding conception of propositions. As a result, we conclude that abandoning worlds by embracing a truthmaker-based approach offers a promising way to account for hyperintensional propositions without facing the paradoxical outcome.

Natural language contains simple lexical items for some but not all Boolean operators. English, for example, contains conjunction and, disjunction or, negated disjunction nor, but no word to express negated conjunction *nand nor any other Boolean connective. Natural language grammar can be described by a logic that expresses what the lexicon can express by its primitives, and the rest compositionally. Such logic for propositional connectives is described here as a bilateral extension of update semantics. The basic intuition is that a (...) context can be updated by assertion or by rejection, and by one or multiple propositions at once. These distinctions suffice to characterize the logic of the lexicon. (shrink)

Some tools introduced by Linnebo to show that mathematical entities are thin objects can also be applied to non-mathematical entities, which have been thought to be thin as well for a variety of reasons. In this paper, I discuss some difficulties and opportunities concerning the application of abstraction and interpretational modalities to mereological sums. In particular, I show that on one hand some prima facie attractive candidates for the role of an explanatory plural abstraction principle for mereological sums (in terms (...) of pluralities of summed entities) are not really explanatory; on the other hand, singular abstraction principles (in terms of single summed entities) are materially inadequate. Nonetheless, explanatory criteria of identity and conditions of existence for mereological sums are provided by classical extensional mereology independent of abstraction principles. Thus, given classical extensional mereology, the reasons why, according to Linnebo, mathematical abstracted entities are thin also hold for mereological sums. Finally, I contend that interpretational modalities can be used to characterise the process by which a subject adds sums of previously admitted entities to the domain of quantification. (shrink)
