The reduction of grounding to causation, or each to a more general relation of which they are species, has sometimes been justified by the impressive inferential capacity of structural equation modelling, causal Bayes nets, and interventionist causal modelling. Many criticisms of this assimilation focus on how causation is inadequate for grounding. Here, I examine the other direction: how treating grounding in the image of causation makes the resulting view worse for causation. The distinctive features of causal modelling that make this (...) connection appealing are distorted beyond use by forcing them to fit onto grounding. The very inferential strength that makes causation attractive is only possible because of a narrow construal of what counts as a causal relation; as soon as that broadens, the inferential capacity markedly diminishes. Making causation suitable for application to grounding spoils what was appealing about causation for this task in the first place. However, grounding need not appeal to causation: causal modelling does not have exclusive claim to structural equation modeling or other formal techniques of modelling structure. I offer a case in favour of a different kind of metaphysical frugality, which tend towards narrow, more restrictive construals of relations like causation or grounding, because then each relation behaves more homogenously. This more homogenous behavior delivers stronger inferential power per relation even though there may be more relations to which one is committed. (shrink)

In June 2002, Arthur Andersen LLP became the first accounting firm in history to be criminally convicted. The repercussions were immense. From a position as one of the leading professional services firms in the world, with 85,000 staff in 84 countries and revenues in excess of $9 billion, Andersen effectively ceased to exist within a matter of months. Although Andersen’s conviction related specifically to a charge of obstructing justice, public attention focused on the audit relationship between (...) class='Hi'>Andersen and its major client, Enron Corporation, particularly the actions (and inactions) that had allowed Enron to post spectacular year-on-year earnings and profit growth. As well as examining events leading up to the demise of Andersen, the case provides an opportunity to consider the broader controversy over accounting and corporate governance practices and, more generally, the pressures found within organisations that can foster unethical conduct. The case was prepared from public sources. (shrink)

This article attempts to comprehend the current issues and hurdles that Indian colleges affiliated with Tamil Nadu State Universities encounter when trying to subscribe to a software that detects plagiarism. The study’s goals are to determine whether colleges employ anti-plagiarism software, whether they ensure that their student-given assignments are free of copyright infringement, whether tutors teach about academic misconduct, and what people seem to think of anti-plagiarism software. We surveyed for this study and distributed the questionnaires among college administrators, principals, (...) and librarians. The study respondents are 15.9 per cent principals, 64.2 per cent library professionals, and 19.9 per cent college administrators. The survey study report shows that 70.9 per cent of the majority of the colleges did not subscribe. 41.7 per cent gave the reason it is too expensive, and 30.5 per cent of respondents thought that for their college, it is unnecessary to subscribe. However, nobody has confirmed whether or not all colleges possess access to plagiarism detection software. Thus, according to this investigation, further Indian states must be involved in this research to understand the specific context fully. This report advises the UGC to enforce the requirement that colleges have plagiarism detection software; they either provide colleges additional money to subscribe to such software, or the university must grant free access to the affiliated colleges.

Mindfulness training has been used to improve emotional wellbeing in early adolescents. However, little is known about treatment outcome moderators, or individual differences that may differentially impact responses to treatment. The current study focused on gender as a potential moderator for affective outcomes in response to school-based mindfulness training. Sixth grade students (N = 100) were randomly assigned to either the six weeks of mindfulness meditation or the active control group as part of a history class curriculum. Participants in the (...) mindfulness meditation group completed short mindfulness meditation sessions four to five times per week, in addition to didactic instruction (Asian history). The control group received matched experiential activity in addition to didactic instruction (African history) from the same teacher with no meditation component. Self-reported measures of emotional wellbeing/affect, mindfulness, and self-compassion were obtained at pre and post intervention. Meditators reported greater improvement in emotional wellbeing compared to those in the control group. Importantly, gender differences were detected, such that female meditators reported greater increases in positive affect compared to females in the control group, whereas male meditators and control males displayed equivalent gains. Uniquely among females but not males, increases in self-reported self-compassion were associated with improvements in affect. These findings support the efficacy of school-based mindfulness interventions, and interventions tailored to accommodate distinct developmental needs of female and male adolescents. (shrink)

This study was conducted to determine the effectiveness of utilizing the Dual-axis Solar Tracker in harnessing solar energy and storing it in lithium-ion batteries in terms of voltage and milliamps per hour gained. This study utilized two solar panel systems, the Static Solar Panel System and the Dual-Axis Solar Tracker and aimed to prove the significant difference generated by solar panel systems in terms of voltage and milliamps per hour. This study employed an Applied Experimental Research Design utilizing Arduino Uno, (...) light-dependent resistors, micro servos, and solar panels to create the Dual-Axis Solar Tracker. The data gathered from the electric quantities during the seven-day sun exposure were tabulated, analyzed, and computed using mean tests, standard deviation, and T-tests to find the significant difference between the two solar panels. Based on the analyses of the data, it was revealed that the Dual-Axis Solar Tracker was superior in terms of voltage and milliamps per hour generated compared to the Static Solar Panel System. Moreover, computations using the T-test found that in terms of voltage and milliamps per hour generated, there was a significant difference between the Dual-Axis Solar Tracker and the Static Solar Panel System. Based on the findings of the study, it is concluded that the utilization of the Dual-Axis Solar Tracker statistically increases the effectiveness of solar panels in harnessing energy generation.

An orbital simulation program is described that uses a geometrical approach to modeling gravitational and atomic orbits at the Planck scale. Orbiting objects A, B, C... are sub-divided into points, each point representing 1 unit of Planck mass, for example, a 1kg satellite would divide into 1kg/Planck mass = 45940509 points. Each point in object A then forms a rotating orbital pair with every point in objects B, C..., resulting in a universe-wide, n-body network of rotating point-to-point orbital pairs. Each (...) orbital pair rotates 1 unit of Planck length per unit of Planck time at velocity c in hypersphere space co-ordinates, the results then summed and averaged giving the new co-ordinates, the program then repeats. When these rotations are mapped over time in a 3D space, objects A, B, C... appear to be orbiting each other. The basic simulation uses the fine structure constant alpha as an orbital constant to simulate gravitational orbit parameters. As each orbital comprises only 2 points, 1 at each orbital pole, information regarding the objects A, B, C... ; momentum, size, center of mass, barycenter etc ... is not required, instead only the start positions (co-ordinates) of each point are used as initial inputs. Each point, by having a mass of Planck mass, is itself a construct of multiple particles, and so we can also form particle to particle orbital pairs, transition energies for the H atom (an electron-proton orbital pair) are well documented and so can be used as reference. Atomic orbital pairs rotate slower than gravitational orbitals by a factor of alpha, 'gravity' therefore stronger than the 'electric force' when measured at the Planck scale. (shrink)

Questo breve volume prende in considerazione, analizza e commenta alcune interpretazioni magistrali della filosofia di Giordano Bruno, che hanno attraversato l'800 ed il '900, indirizzandone l'orizzonte di comprensione. Il testo inizia con l'interpretazione di G.W.F. Hegel e di B. Spaventa, per poi accedere a quella di G. Gentile. Il volume si conclude con l'analisi ed il commento dell'interpretazione fornita da N. Badaloni. Una piccola bibliografia bruniana conclude il testo.

C’è un modo per ristabilire il legame fiduciario tra il ceto politico e gli elettori, rendere le decisioni dell’amministrazione pubblica più adeguate ai bisogni delle persone e, al contempo, accrescere la solidarietà nelle comunità locali e migliorare il livello culturale della popolazione? Non vi sono soluzioni definitive ma qualsiasi tentativo presuppone una responsabilità diffusa: il coinvolgimento di cittadini, associazioni, imprese e altri interessi e punti di vista organizzati, dal cui confronto si genera un’intelligenza collettiva in grado di rendere coscienti delle (...) sfide comuni, affermare i principi di dialogo e ragionevolezza e, finanche, concepire innovazioni inaspettate. I processi partecipativi sono la procedura che istituzionalizza questa prospettiva deliberativa della democrazia e il progetto “Un Parco grande come una Città”, promosso dal Comune di Pisa nel quadro della legge n. 48/2013 della Regione Toscana, è una riuscita sperimentazione.

The high prevalence of brain injury incidents in adolescence and adulthood demands effective models for re-learning lost cognitive abilities. Impairment in brain injury survivors’ higher-level cognitive functions is common and a negative predictor for long-term outcome. We conducted two small-scale interventions (N = 12; 33.33% female) with persons with acquired brain injuries in two municipalities in Sweden. Age ranged from 17 to 65 years (M = 51.17, SD = 14.53). The interventions were dialogic, inquiry-based, and inspired by the Philosophy for (...) Children Programme, a participatory thinking skills approach with documented higher-order cognitive outcomes, such as developed argumentation skills, in other target groups. Philosophical dialogues were conducted once a week in the two groups, totalling 12 dialogues per group. Group argumentation development was measured through compared scores from structured observations of filmed dialogues early and late in the intervention. Large positive changes in mean scores from early to late in the intervention, together with constantly high facilitator quality, suggest argumentation development in the sample due to the intervention.

In Modal Logic as Metaphysics, Timothy Williamson claims that the possibilism-actualism (P-A) distinction is badly muddled. In its place, he introduces a necessitism-contingentism (N-C) distinction that he claims is free of the confusions that purportedly plague the P-A distinction. In this paper I argue first that the P-A distinction, properly understood, is historically well-grounded and entirely coherent. I then look at the two arguments Williamson levels at the P-A distinction and find them wanting and show, moreover, that, when the N-C (...) distinction is broadened (as per Williamson himself) so as to enable necessitists to fend off contingentist objections, the P-A distinction can be faithfully reconstructed in terms of the N-C distinction. However, Williamson’s critique does point to a genuine shortcoming in the common formulation of the P-A distinction. I propose a new definition of the distinction in terms of essential properties that avoids this shortcoming. (shrink)

Studies in the psychology of visual expertise have tended to focus on a limited set of expert domains, such as radiology and athletics. Conclusions drawn from these data indicate that experts use parafoveal vision to process images holistically. In this study, we examined a novel, as-of-yet-unstudied class of visual experts—architects—expecting similar results. However, the results indicate that architects, though visual experts, may not employ the holistic processing strategy observed in their previously studied counterparts. Participants (n = 48, 24 architects, 24 (...) naïve) were asked to find targets in chest radiographs and perspective images. All images were presented in both gaze-contingent and normal viewing conditions. Consistent with a holistic processing model, we expected two results: (1) architects would display a greater difference in saccadic amplitude between the gaze- contingent and normal conditions, and (2) architects would spend less time per search than an undergraduate control group. We found that the architects were more accurate in the perspectival task, but they took more time and displayed a lower difference in saccadic amplitude than the controls. Our research indicates a disjunctive conclusion. Either architects are simply different kinds of visual experts than those previously studied, or we have generated a task that employs visual expertise without holistic processing. Our data suggest a healthy skepticism for across-the-board inferences collected from a single domain of expertise to the nature of visual expertise generally. More work is needed to determine whether holism is a feature of all visual expertise. (shrink)

Background: The internationalization of clinical studies requires a shared understanding of the fundamental ethical values guiding clinical studies. It is important that these values are not only embraced at the legal level but also adopted by clinicians themselves during clinical studies. Objective: Our goal is to provide an insight on how clinicians in Germany and Poland perceive and identify the different ethical issues regarding informed consent in clinical studies. Methods: To gain an understanding of how clinicians view clinical studies in (...) the countries they work in, we carried out semi-structured problem-centered interviews per telephone in Poland (n = 6) and Germany (n = 6). Our interviewees concentrated on three main topics: an appraisal of the normative framework, challenges in the information process and the protection of all participants in clinical studies. Results: Clinicians generally supported the normative framework, even though they considered it quite complex. In the two study countries, a widely noted dilemma in the information process was whether to overburden participants with extensive information or risking leaving out important facts. Clinicians were ready to exclude larger population groups from participating in clinical studies when the information process could not be carried out with standard procedures or when their inclusion was ethically sensitive. Conclusion: Clinicians need to gain a better understanding of the consequences of excluding larger population groups form participating in clinical studies. They should seek assistance in improving the information process for the inclusion of underrepresented groups in clinical studies. (shrink)

Nel primo paragrafo sarà esaminato l’impianto normativo che regola le pubbliche amministrazioni, riformato dalle l. n. 142 e n. 241 del 1990, dal D.Lgs. 29/1993, dalle “leggi Bassanini” e dalla legge-quadro 150/2000, sia riguardo al diritto di accesso nei confronti dell’attività dell’amministrazione, sia in merito al radicamento di criteri di efficacia, efficienza ed economicità delle policies sia agli strumenti con cui gli Enti locali e cittadini possono comunicare. Gli anni ‘90 segnano l’inizio di un processo volto alla riorganizzazione delle PA (...) a partire dalla centralità della comunicazione istituzionale ma anche della concezione del “diritto all’informazione” nelle tre accezioni di diritto “di informare, “di informarsi” e “essere informati”. La Levi ha ben sottolineato “la rapidità inusuale nella storia nazionale” di tale riforma e la centralità assunta in essa dalle dimensioni dell’informazione, della comunicazione e della partecipazione: "In sintesi, si può ritenere legittimo concludere che le riforme del decennio 1990-2000 abbiano segnato il passaggio dal segreto alla trasparenza e dall’unilateralità alla partecipazione. Le politiche di modernizzazione in tema di comunicazione pubblica e di maggiore trasparenza dell’attività dell’amministrazione si sono mosse verso una più marcata tutela dei diritti dei cittadini e verso l’accentuazione del risultato dell’azione amministrativa" (2004, p. 16). Grandi ha ribadito che tale evoluzione costituisce nella cultura politica dello stato di diritto una «sorta di pre-condizione dell’emergere dei nuovi diritti di cittadinanza, intesi quale partecipazione consapevole e informata al processo decisionale pubblico» (Grandi 20022, 13). Nel secondo paragrafo verranno descritte gli ambiti di applicazione, le finalità, gli obiettivi e le strutture della comunicazione istituzionale disciplinate dalla legge n. 150/2000 e dai conseguenti regolamenti attuativi: il Portavoce, l’Ufficio stampa, l’Ufficio per le relazioni al pubblico. Come vedremo, si tratta di una normativa che rappresenta un punto di arrivo e un punto di partenza, in quanto, da un lato, se chiude il decennio delle riforme amministrative, d’altro lato, problematizza compiutamente per la prima volta il rapporto di comunicazione tra PA e cittadini e pone in evidenza tutte le difficoltà nell’implementare le norme nella realtà. Agli elementi critici della comunicazione istituzionale sono riservate le considerazioni conclusive: dal reclutamento e formazione del personale, al coordinamento delle strutture, dal persistere di mentalità burocratiche e autoreferenziale alla carenza di risorse. Il problema delle dotazioni organiche e finanziarie, in particolare, è molto sentito dalle amministrazioni di dimensioni più piccole, le quali spesso ricorrono alla “esternalizzazione” di attività degli uffici di comunicazione, non solo per la produzione editoriale, le campagne pubblicitarie e i servizi di gestione degli eventi, ma anche per il sito internet e i compiti di informazione più tradizionali. In tale situazione, la comunicazione istituzionale, pur dichiarata come strategica, rischia di rimanere un momento residuale dell’azione pubblica sia in termini di processo sia in termini di contenuto, slegata dagli obiettivi dell’organizzazione.

Although it is well known that Gestalt theory had an important impact on Merleau-Ponty’s philosophy throughout his career, there is still no detailed study either of its influence on his ideas or of his own understanding of the notoriously polysemic notion of Gestalt. Yet, this notion is a key to Merleau-Ponty’s fundamental project of overcoming “objective thought” and its inherent dichotomies. By indicating how signification or ideality can be immanent in, rather than opposed to, matter, it compels us to redefine (...) both consciousness and the world it is bound up with. The aim of this article is to clarify Merleau-Ponty’s notion of Gestalt against the historical background that he refers to, including Kurt Goldstein’s theory of the organism that was crucial for his interpretation of it. -/- On sait que la théorie de la Gestalt a eu un impact majeur sur la philosophie merleaupontienne. Il n’existe pourtant pas d’étude extensive de l’influence de cette théorie sur les thèses de Merleau-Ponty ou sur sa compréhension propre de la notion fort polysémique de Gestalt. Or cette notion s’avère être l’une des meilleures clés pour comprendre le projet fondamental du dépassement merleau-pontien de la « pensée objective » et de ses dichotomies. En effet, en montrant comment le sens ou l’idéalité sont immanents, plutôt qu’opposés, à la matière, la Gestalt conduit à définir à nouveaux frais la conscience et le monde auquel elle est liée. L’article vise à clarifier la conception de la Gestalt chez Merleau-Ponty à partir de son fond historique. On étudie en particulier la théorie de l’organisme de Kurt Goldstein, qui a été essentielle pour l’interprétation merleaupontienne de la notion de Gestalt. -/- Benché sia noto che la Gestalttheorie abbia avuto un impatto rilevante sull’intero tragitto della filosofia di Merleau-Ponty, non esiste ancora uno studio dettagliato dell’influenza del gestaltismo sulle sue idee né sulla sua comprensione di un concetto notoriamente sfaccettato come quello di Gestalt. Tuttavia proprio questa nozione costituisce una chiave d’accesso fondamentale al grande progetto merleaupontyano di oltrepassare il “pensiero oggettivo” insieme alle dicotomie che lo accompagnano. Indicando come il significato o l’idealità possano essere immanenti, anziché opposti, alla materia, tale nozione ci obbliga a ridefinire tanto la coscienza quanto il mondo a cui essa è legata. L’obiettivo di questo articolo è quello di chiarire la nozione merleaupontyana di Gestalt nel suo contesto storico, con particolare riferimento alla teoria dell’organismo elaborata da Kurt Goldstein, determinante per l’interpretazione merleaupontyana della nozione di Gestalt.

Objective: Eye injuries are one of the leading causes of disabling ocular morbidity. The objective of this bibliometric study was to evaluate the top 100 cited articles on ocular trauma published between 1975 and 2018 via multidimensional citation analysis. Methods: We analyzed the top 100 cited articles among 3,768 ocular trauma articles published between 1975 and 2018; these articles were obtained from the databases in Web of Science and PubMed based on their citation rates per article, publication years, countries of (...) origin, institutions or organizations, the most common subjects, funding status, article types, and levels of evidence. The data obtained were analyzed with the SPSS® 20.0 software package program. Results: In the top 100 cited articles on ocular trauma, the total number of authors was 420 and the average authorship was 4.20±2.23 (range: 1–14). In our study, 70 of the top 100 cited articles were published in journals with an impact factor (IF) of ≥2.00 (range: 2.016–8.806), and Q index or quartile score of these journals was mostly Q1. Although the most preferred journal was Ophthalmology according to the total number of citations and articles (n=2,183 and n=23, respectively), Eye was the most preferred journal according to the mean number of citations per article. Besides, the three most common topics among the top 100 cited articles were mechanical eyeball injury (40 articles), epidemiology of ocular trauma (19 articles), and traumatic eye infection (17 articles). The average level of evidence was found to be 3.14±0.66 (range: 1–4), and the mean number of citations per article was the highest level at 2. Moreover, we also found that the most commonly preferred article type by authors was clinical research (92 articles), and most of them were in the B level of evidence group (70 articles). Conclusion: Analysis of the top 100 most cited articles on ocular trauma as an update study can provide us scientific contributions and vital current data in clinical implementations. (shrink)

L’obra Somnis d’un visionari, il·lustrats mitjançant els somnis de la metafísica (1766) d’Immanuel Kant presenta un tractament juxtaposat i obertament irònic de dues temàtiques a primera vista heterogènies: la manera de fer metafísica habitual al context germànic del s. xvii i les visions sobrenaturals d’Emmanuel Swedenborg. Aquest article revisa una ambivalència interpretativa interna a l’obra, inicialment identificada per Moses Mendelssohn, que sorgeix d’aquesta juxtaposició temàtica. Segons les dues postures oposades de l’ambivalència pot classificar-se la recepció històrica de l’obra. Seguidament, es (...) mostra la insuficiència d’algunes estratègies habituals d’interpretació del text, i se’n proposa una de nova basada en dues nocions del text, a saber, la voluntat d’assegurar un món comú i la noció de saviesa. A partir d’aquestes nocions i d’una carta que Kant escriu a Mendelssohn s’aporta una lectura del text que, finalment, se situa en referència a les dues lectures de l’ambivalència interpretativa presentada inicialment. -/- Immanuel Kant’s Dreams of a spirit-seer elucidated by dreams of metaphysics (1766) presents a juxtaposed and openly ironic treatment of two apparently heterogeneous subjects: the way of doing metaphysics common in the Seventeenth-Century German context and Emmanuel Swedenborg’s supernatural visions. This article reviews an interpretative ambivalence internal to the work originally identified by Moses Mendelssohn, which springs from its thematic juxtaposition. One may classify the work’s historical reception according to the two stances on the ambivalence. Furthermore, the insufficiency of some common strategies for interpreting the text will be shown, and a new one is proposed on the basis of two notions that appear within the text, that is, the will to ensure a common world and the notion of wisdom. As a result of these notions and on the basis of a letter that Kant wrote to Mendelssohn, a reading of this work is proposed, which is finally situated with respect to the two readings of the interpretative ambivalence initially presented.

We review our approach to quantum mechanics adding also some new interesting results. We start by giving proof of two important theorems on the existence of the A(Si) and i,±1 N Clifford algebras. This last algebra gives proof of the von Neumann basic postulates on the quantum measurement explaining thus in an algebraic manner the wave function collapse postulated in standard quantum theory. In this manner we reach the objective to expose a self-consistent version of quantum mechanics. In detail we (...) realize a bare bone skeleton of quantum mechanics recovering all the basic foundations of this theory on an algebraic framework. We give proof of the quantum like Heisenberg uncertainty relations using only the basic support of the Clifford algebra. In addition we demonstrate the well known phenomenon of quantum Mach Zender interference using the same algebraic framework, as well as we give algebraic proof of quantum collapse in some cases of physical interest by direct application of the theorem that we derive to elaborate the i,±1 N algebra. We also discuss the problem of time evolution of quantum systems as well as the changes in space location, in momentum and the linked invariance principles. We are also able to re-derive the basic wave function of standard quantum mechanics by using only the Clifford algebraic approach. In this manner we obtain a full exposition of standard quantum mechanics using only the basic axioms of Clifford algebra. We also discuss more advanced features of quantum mechanics. In detail, we give demonstration of the Kocken-Specher theorem, and also we give an algebraic formulation and explanation of the EPR paradox only using the Clifford algebra. By using the same approach we also derive Bell inequalities. Our formulation is strongly based on the use of idempotents that are contained in Clifford algebra. Their counterpart in quantum mechanics is represented by the projection operators that, as it is well known, are interpreted as logical statements, following the basic von Neumann results. Von Neumann realized a matrix logic on the basis of quantum mechanics. Using the Clifford algebra we are able to invert such result. According to the results previously obtained by Orlov in 1994, we are able to give proof that quantum mechanics derives from logic. We show that indeterminism and quantum interference have their origin in the logic. Therefore, it seems that we may conclude that quantum mechanics, as it appears when investigated by the Clifford algebra, is a two-faced theory in the sense that it looks from one side to “matter per se”, thus to objects but simultaneously also to conceptual entities. We advance the basic conclusion of the paper: There are stages of our reality in which we no more can separate the logic ( and thus cognition and thus conceptual entity) from the features of “matter per se”. In quantum mechanics the logic, and thus the cognition and thus the conceptual entity-cognitive performance, assume the same importance as the features of what is being described. We are at levels of reality in which the truths of logical statements about dynamic variables become dynamic variables themselves so that a profound link is established from its starting in this theory between physics and conceptual entities. Finally, in this approach there is not an absolute definition of logical truths. Transformations , and thus … “redefinitions”…. of truth values are permitted in such scheme as well as the well established invariance principles, clearly indicate . (shrink)

RESUMO -/- Este estudo aborda a análise econômica e zootécnica de um sistema de criação de gado de corte implementado na Fazenda Escola Lagoa do Sino (FELS), localizada em Buri - SP. O estudo baseou-se em um extenso levantamento de dados obtidos ao longo do ciclo produtivo que se estendeu do final de 2022 até janeiro de 2024. A FELS, com uma área de aproximadamente 21 hectares de pastagens destinada a esta pesquisa, emprega um sistema de manejo composto por dois (...) funcionários. O rebanho, constituído por 14 vacas ½ Nelore e ½ Angus, juntamente com um touro registrado PO da raça taurina Senepol, é alimentado exclusivamente por pastagens de Brachiaria decumbens, complementada por suplementação mineral. A avaliação econômica foi conduzida considerando custos operacionais, resultando em um déficit significativo no primeiro ciclo produtivo, principalmente devido a investimentos iniciais como a aquisição de animais. No entanto, uma análise mais profunda indicou que a otimização dos custos operacionais, especialmente relacionados à mão de obra, poderia reduzir esse déficit para um patamar mais gerenciável, sinalizando uma trajetória de aprimoramento nos ciclos subsequentes. Os índices zootécnicos desempenharam um papel crucial na análise da viabilidade econômica, os resultados foram comparados a benchmarks nacionais e estudos anteriores, revelando pontos fortes, como a taxa de fertilidade das vacas, que superou a média nacional. No entanto, foi identificado um desvio significativo no valor da carne produzida por hectare, indicando a necessidade de uma investigação mais detalhada sobre variáveis específicas do sistema. Diante dos desafios iniciais, a pesquisa conclui que a continuidade do estudo, aliada à implementação de estratégias identificadas para aprimoramento, é essencial para consolidar um sistema eficiente e economicamente viável. A busca contínua por eficiência, revisão de insumos na alimentação, aprimoramento do manejo nutricional e estratégias de gestão de recursos humanos são destacadas como áreas-chave para aprimorar a rentabilidade nos ciclos subsequentes. Sendo assim, a pesquisa contribui não apenas para a compreensão do desempenho econômico do sistema, mas também para a identificação de estratégias práticas que podem ser implementadas para aprimorar a eficiência e a rentabilidade na produção de gado de corte.

ABSTRACT This study addresses the economic and zootechnical analysis of a beef cattle farming system implemented at the Lagoa do Sino School Farm (FELS), located in Buri - SP. The study was based on an extensive data collection carried out throughout the productive cycle, spanning from late 2022 to January 2024. FELS, with an area of approximately 21 hectares of pastures dedicated to this research, employs a management system consisting of two employees. The herd, comprised of 14 ½ Nelore and ½ Angus cows, along with a registered Senepol PO breed bull, is exclusively fed on Brachiaria decumbens pastures, supplemented with mineral supplementation. The economic evaluation was conducted considering operational costs, resulting in a significant deficit in the first productive cycle, mainly due to initial investments such as the acquisition of animals. However, a deeper analysis indicated that the optimization of operational costs, especially related to labor, could reduce this deficit to a more manageable level, signaling an improvement trajectory in subsequent cycles. Zootechnical indices played a crucial role in the analysis of economic viability, and the results were compared to national benchmarks and previous studies, revealing strengths such as the fertility rate of cows, which exceeded the national average. However, a significant deviation was identified in the value of meat produced per hectare, indicating the need for a more detailed investigation into specific variables of the system. Facing initial challenges, the research concludes that the continuity of the study, coupled with the implementation of identified improvement strategies, is essential to consolidate an efficient and economically viable system. The ongoing pursuit of efficiency, the review of inputs in feed, improvement of nutritional management, and human resource management strategies are highlighted as key areas to enhance profitability in subsequent cycles. Thus, the research contributes not only to understanding the economic performance of the system but also to identifying practical strategies that can be implemented to improve efficiency and profitability in beef cattle production.

Background: Tuberculosis is among the major causes of illness and death worldwide especially in Asia. Smoking is associated with recurrent tuberculosis and its related mortality. Also, it could affect clinical manifestations, bacteriological conversion and outcome of treatment. This study aimed to evaluate the pattern of tobacco smoking, history of previous quit attempts and attitude towards quitting in tuberculosis patients. Materials and Methods: It was a cross-sectional study done amongst tuberculosis patients presented to DOTS corner of Rajshahi Medical College Hospital. 315 (...) patients entered the study as "First Come First Serve". Selfreported questionnaires were designed according to the standard questionnaires of smoking pattern. Results: Sixty one percent (61%) patients (n=192) were smoker before the diagnosis of tuberculosis. 51.1% were current smokers at the time of interview and were continuing smoking after the diagnosis of tuberculosis. Only 10.2% discontinued smoking after diagnosis. 68.2% smokes less than 10 cigarettes per day. 53.1% was between 31-50 age group. 21-30 is the commonest age group (62%) to start smoking is and 66.1% smoked less than 10 years before diagnosis. To reduce stress was the most common cause to continue smoking (48.9%). 71.9% smokers showed keen interest to stop smoking. Conclusion: Considering the prevalence of smoking in tuberculosis patients, evaluation of tobacco smoking status in such patients and motivating them to quit smoking could be considered as important steps in their treatment process.

La sincronicità, è “la simultaneità di un certo stato psichico con uno o più eventi esterni che paiono paralleli significativi della condizione momentaneamente soggettiva” (Jung, 1952). C.G.Jung e il fisico quantistico premio Nobel, W. Pauli, ci introducono con tale concettualizzazione in un mondo, nel quale ciò che è interno e ciò che è esterno a noi non è così nettamente definito, mondo nel quale le “coincidenze” non sono più tali, ma rivestono un significato ed un’importanza per la nostra psiche, per (...) la nostra vita. Se un bambino mentre gioca sulla riva di un fiume, vi cade e rischia di venire trascinato dalla corrente, e nello stesso momento sua madre dall’altra parte della città è preda di un’angoscia che l’attanaglia e grida: “il mio bambino!”, siamo in presenza di un evento sincronistico, nel senso della definizione di Jung sopracitata. Noi crediamo, sulla scia di Jung e Pauli che la sincronicità possa essere un possibile principio esplicativo della realtà da affiancare alla causalità, per Pauli vi sono nella realtà sia elementi razionali sia irrazionali ed è quindi impossibile per la fisica dire l’ultima parola sulla realtà, visto che quest’ultima è così complessa. L’attuazione dei fenomeni sincronistici è fuori dalla portata di qualsiasi tipo di previsione razionale, l’evento sincronistico non è riproducibile ed è in qualche modo l’emblema dell’aspetto non razionale della realtà, e come detto, insieme alla più consueta logica causalistica, (ad esempio, una mela su un albero quando è matura può anche cadere), danno una visione più completa della realtà. E questa visione più completa era l’intento di Jung nell’approcciare questi fenomeni: “Cercare di aprire una via verso “l’animazione della materia” a partire dall’assunzione che “ciò che esiste sia dotato di senso”…” ( Pauli e Jung 1992, lettera n.59 di Jung, p. 100).

The study is based on primary data which are collected with the help of a structured schedule from four different castes of population spread over North Tripura District and Unokuti District of Tripura. Stratified random sampling technique was applied for the collection of data at household level where the sample units are the adult women in the age group of 18 - 55 years. All the data are collected based on the criteria of balanced representation of different social castes such (...) as ST, SC, OBC and General in the sample. Altogether 90 samples have been collected. Main objective of the study is to determine the morbidity status and also to determine the key variables which affect morbidity status of the people of North Tripura. Binary logistic regression model has been applied to determine the key determinants of morbidity status. It has been found that age of the respondent, respondents per day calorie intake and educational level of the respondents are the key determinants of morbidity status of the respondents. The model as a whole explained between 30.6% (Cox & Snell R Square) and 41.1 %( Nagelkerke R Square). And ᵡ2 (6.460, N=90) =32.811. (shrink)

This paper articulates an account of causation as a collection of information-theoretic relationships between patterns instantiated in the causal nexus. I draw on Dennett’s account of real patterns to characterize potential causal relata as patterns with specific identification criteria and noise tolerance levels, and actual causal relata as those patterns instantiated at some spatiotemporal location in the rich causal nexus as originally developed by Salmon. I develop a representation framework using phase space to precisely characterize causal relata, including their degree (...) of counterfactual robustness, causal profiles, causal connectivity, and privileged grain size. By doing so, I show how the philosophical notion of causation can be rendered in a format that is amenable for direct application of mathematical techniques from information theory such that the resulting informational measures are causal informational measures. This account provides a metaphysics of causation that supports interventionist semantics and causal modeling and discovery techniques. (shrink)

Over the last decades, science has grown increasingly collaborative and interdisciplinary and has come to depart in important ways from the classical analyses of the development of science that were developed by historically inclined philosophers of science half a century ago. In this paper, I shall provide a new account of the structure and development of contemporary science based on analyses of, first, cognitive resources and their relations to domains, and second of the distribution of cognitive resources among collaborators and (...) the epistemic dependence that this distribution implies. On this background I shall describe different ideal types of research activities and analyze how they differ. Finally, analyzing values that drive science towards different kinds of research activities, I shall sketch the main mechanisms underlying the perceived tension between disciplines and interdisciplinarity and argue for a redefinition of accountability and quality control for interdisciplinary and collaborative science.

A finer-grained delineation of a given explanandum reveals a nexus of closely related causal and non- causal explanations, complementing one another in ways that yield further explanatory traction on the phenomenon in question. By taking a narrower construal of what counts as a causal explanation, a new class of distinctively mathematical explanations pops into focus; Lange’s characterization of distinctively mathematical explanations can be extended to cover these. This new class of distinctively mathematical explanations is illustrated with the Lotka-Volterra equations. There (...) are at least two distinct ways those equations might hold of a system, one of which yields straightforwardly causal explanations, but the other of which yields explanations that are distinctively mathematical in terms of nomological strength. In the first, one first picks out a system or class of systems, finds that the equations hold in a causal -explanatory way; in the second, one starts with the equations and explanations that must apply to any system of which the equations hold, and only then turns to the world to see of what, if any, systems it does in fact hold. Using this new way in which a model might hold of a system, I highlight four specific avenues by which causal and non- causal explanations can complement one another. (shrink)

The aim of this paper is threefold. Firstly, §1 and §2 introduce the novel concept logical akrasia by analogy to epistemic akrasia. If successful, the initial sections will draw attention to an interesting akratic phenomenon which has not received much attention in the literature on akrasia (although it has been discussed by logicians in different terms). Secondly, §3 and §4 present a dilemma related to logical akrasia. From a case involving the consistency of Peano Arithmetic and Gödel’s Second Incompleteness Theorem (...) it’s shown that either we must be agnostic about the consistency of Peano Arithmetic or akratic in our arithmetical theorizing. If successful, these sections will underscore the pertinence and persistence of akrasia in arithmetic (by appeal to Gödel’s seminal work). Thirdly, §5 concludes by suggesting a way of translating the dilemma of arithmetical akrasia into a case of regular epistemic akrasia; and further how one might try to escape the dilemma when it’s framed this way.

This paper discusses the Uniqueness Thesis, a core thesis in the epistemology of disagreement. After presenting uniqueness and clarifying relevant terms, a novel counterexample to the thesis will be introduced. This counterexample involves logical disagreement. Several objections to the counterexample are then considered, and it is argued that the best responses to the counterexample all undermine the initial motivation for uniqueness.

Even though the evidence‐based medicine movement (EBM) labels mechanisms a low quality form of evidence, consideration of the mechanisms on which medicine relies, and the distinct roles that mechanisms might play in clinical practice, offers a number of insights into EBM itself. In this paper, I examine the connections between EBM and mechanisms from several angles. I diagnose what went wrong in two examples where mechanistic reasoning failed to generate accurate predictions for how a dysfunctional mechanism would respond to intervention. (...) I then use these examples to explain why we should expect this kind of mechanistic reasoning to fail in systematic ways, by situating these failures in terms of evolved complexity of the causal system(s) in question. I argue that there is still a different role in which mechanisms continue to figure as evidence in EBM: namely, in guiding the application of population‐level recommendations to individual patients. Thus, even though the evidence‐based movement rejects one role in which mechanistic reasoning serves as evidence, there are other evidentiary roles for mechanistic reasoning. This renders plausible the claims of some critics of evidencebased medicine who point to the ineliminable role of clinical experience. Clearly specifying the ways in which mechanisms and mechanistic reasoning can be involved in clinical practice frames the discussion about EBM and clinical experience in more fruitful terms.

A key question in the philosophy of logic is how we have epistemic justification for claims about logical entailment (assuming we have such justification at all). Justification holism asserts that claims of logical entailment can only be justified in the context of an entire logical theory, e.g., classical, intuitionistic, paraconsistent, paracomplete etc. According to holism, claims of logical entailment cannot be atomistically justified as isolated statements, independently of theory choice. At present there is a developing interest in—and endorsement of—justification holism (...) due to the revival of an abductivist approach to the epistemology of logic. This paper presents an argument against holism by establishing a foundational entailment-sentence of deduction which is justified independently of theory choice and outside the context of a whole logical theory.

In this field guide, I distinguish five separate senses with which the term ‘mechanism’ is used in contemporary philosophy of science. Many of these senses have overlapping areas of application but involve distinct philosophical claims and characterize the target mechanisms in relevantly different ways. This field guide will clarify the key features of each sense and introduce some main debates, distinguishing those that transpire within a given sense from those that are best understood as concerning distinct senses. The ‘new mechanisms’ (...) sense is at the center of most of these contemporary debates and will be treated at greater length; subsequent senses of mechanism will be primarily distinguished from this one. In part I of this paper, I distinguish two senses of the term ‘mechanism’, both of which are explicitly hierarchical and nested in character, such that any given mechanism is comprised of smaller sub-mechanisms, in turn comprised of yet smaller sub-sub-mechanisms and so on. While both of the senses discussed here are anti-reductive, they differ in their focus on scientific practice versus metaphysics, in the degree of regularity they attribute to mechanisms, and in terms of their relationships to the discussions of mechanisms in the history of philosophy and science.

In this field guide, I distinguish five separate senses with which the term ‘mechanism’ is used in contemporary philosophy of science. Many of these senses have overlapping areas of application but involve distinct philosophical claims and characterize the target mechanisms in relevantly different ways. This field guide will clarify the key features of each sense and introduce some main debates, distinguishing those that transpire within a given sense from those that are best understood as concerning two distinct senses. The ‘new (...) mechanisms’ sense is the primary sense from which other senses will be distinguished. In part II of this field guide, I consider three further senses of the term that are ontologically ‘flat’ or at least not explicitly hierarchical in character: equations in structural equation models of causation, causal-physical processes, and information-theoretic constraints on states available to systems. After characterizing each sense, I clarify its ontological commitments, its methodological implications, how it figures in explanations, its implications for reduction, and the key manners in which it differs from other senses of mechanism. I conclude that there is no substantive core meaning shared by all senses, and that debates in contemporary philosophy of science can benefit from clarification regarding precisely which sense of mechanism is at stake.

The Formalist tradition in late-scholastic philosophy has gone unnoticed in standard historiography. This article’s overall objective is to add the Formalist tradition to what we know about Renaissance philosophy. I first show how the Formalist tradition was born out of some innovative considerations of hierarchies of distinctions in the wake of the Franciscan John Duns Scotus’s teaching on the formal distinction in the beginning of the fourteenth century (especially Francis of Meyronnes’s model of four distinctions and Petrus Thomae’s more elaborate (...) doctrine of seven kinds of distinctions). I then trace how Formalist literature developed from being an exclusively Franciscan affair to becoming a much more widespread phenomenon. Thus, from the decades up to 1500 and onwards, authors from various late-scholastic schools (Thomism, Lullism, Averroism, and others) produced Formalist literature, i.e., treatises on multiple kinds of distinctions. I highlight particularly how one Franciscan philosopher of the sixteenth century, Jean Du Douet, proposed to view the Formalist preoccupation with distinctions as a discipline in its own right, a proper scientia formalitatum. I finally argue that while this proposal met with dismissive reactions, Du Douet’s idea does in fact reflect the role Formalism played in the scholastic curriculum in the late sixteenth century, at least in Franciscan milieus.

How regular do mechanisms need to be, in order to count as mechanisms? This paper addresses two arguments for dropping the requirement of regularity from the definition of a mechanism, one motivated by examples from the sciences and the other motivated by metaphysical considerations regarding causation. I defend a broadened regularity requirement on mechanisms that takes the form of a taxonomy of kinds of regularity that mechanisms may exhibit. This taxonomy allows precise explication of the degree and location of regular (...) operation within a mechanism, and highlights the role that various kinds of regularity play in scientific explanation. I defend this regularity requirement in terms of regularity’s role in individuating mechanisms against a background of other causal processes, and by prioritizing mechanisms’ ability to serve as a model of scientific explanation, rather than as a metaphysical account of causation. It is because mechanisms are regular, in the expanded sense described here, that they are capable of supporting the kinds of generalizations that figure prominently in scientific explanations.

Default logic has been a very active research topic in artificial intelligence since the early 1980s, but has not received as much attention in the philosophical literature thus far. This paper shows one way in which the technical tools of artificial intelligence can be applied in contemporary epistemology by modeling a paradigmatic case of deep disagreement using default logic. In §1 model-building viewed as a kind of philosophical progress is briefly motivated, while §2 introduces the case of deep disagreement we (...) aim to model. On the heels of this, §3 defines our formal framework, viz., a refined Horty-style default logic. §4 then uses the framework to model deep disagreement, and finally §5 provides a critical discussion of the result.

Leuridan (2010) argued that mechanisms cannot provide a genuine alternative to laws of nature as a model of explanation in the sciences, and advocates Mitchell’s (1997) pragmatic account of laws. I first demonstrate that Leuridan gets the order of priority wrong between mechanisms, regularity, and laws, and then make some clarifying remarks about how laws and mechanisms relate to regularities. Mechanisms are not an explanatory alternative to regularities; they are an alternative to laws. The existence of stable regularities in nature (...) is necessary for either model of explanation: regularities are what laws describe and what mechanisms explain. (shrink)

Humean accounts of laws are often contrasted with governing accounts, and recent developments have added pragmatic versions of Humeanism. This paper offers Mitchell's pragmatist, perspectival account of laws as a third option. The differences between these accounts come down to the role of modality. Mitchell's bottom-up account allows for subtle gradations of modal content to be conveyed by laws. The perspectival character of laws is not an accident or something to be eventually eliminated - it is part of how this (...) modal content is conveyed. I conclude with a discussion of the metaphysical commitments in Humeanism as requiring a perspectiveless view of the manifold from outside, and how Mitchell's situated account is better able to account for the substantive notion of possibility involved in scientific laws.

While the epistemic significance of disagreement has been a popular topic in epistemology for at least a decade, little attention has been paid to logical disagreement. This monograph is meant as a remedy. The text starts with an extensive literature review of the epistemology of (peer) disagreement and sets the stage for an epistemological study of logical disagreement. The guiding thread for the rest of the work is then three distinct readings of the ambiguous term ‘logical disagreement’. Chapters 1 and (...) 2 focus on the Ad Hoc Reading according to which logical disagreements occur when two subjects take incompatible doxastic attitudes toward a specific proposition in or about logic. Chapter 2 presents a new counterexample to the widely discussed Uniqueness Thesis. Chapters 3 and 4 focus on the Theory Choice Reading of ‘logical disagreement’. According to this interpretation, logical disagreements occur at the level of entire logical theories rather than individual entailment-claims. Chapter 4 concerns a key question from the philosophy of logic, viz., how we have epistemic justification for claims about logical consequence. In Chapters 5 and 6 we turn to the Akrasia Reading. On this reading, logical disagreements occur when there is a mismatch between the deductive strength of one’s background logic and the logical theory one prefers (officially). Chapter 6 introduces logical akrasia by analogy to epistemic akrasia and presents a novel dilemma. Chapter 7 revisits the epistemology of peer disagreement and argues that the epistemic significance of central principles from the literature are at best deflated in the context of logical disagreement. The chapter also develops a simple formal model of deep disagreement in Default Logic, relating this to our general discussion of logical disagreement. The monograph ends in an epilogue with some reflections on the potential epistemic significance of convergence in logical theorizing. (shrink)

This paper discusses the uniqueness thesis, a core thesis in the epistemology of disagreement. After presenting uniqueness and clarifying relevant terms, a novel counterexample to the thesis will be introduced. This counterexample involves logical disagreement. Several objections to the counterexample are then considered, and it is argued that the best responses to the counterexample all undermine the initial motivation for uniqueness.

I highlight a metaphysical concern that stands in the way of more widespread adoption of causal modeling techniques such as causal Bayes nets. Researchers in some fields may resist adoption due to concerns that they don't 'really' understand what they are saying about a system when they apply such techniques. Students in these fields are repeated exhorted to be cautious about application of statistical techniques to their data without a clear understanding of the conditions required for those techniques to yield (...) genuine insight into the data. They are acutely aware that anyone can chuck some data into a software package and get what looks like an answer, even though these tests may not be well-defined for the data on which they can apparently be run. This is thus a healthy skepticism for uptake of causal modeling methods, which points directly to the need for a metaphysical understanding of causation in order to successfully use the modeling methods. Without a clear understanding of what the methods are committing to, including what it means to say that there exists a causal relationship, researchers have limited ability to identify potentially bad output, or to independently verify results.

In his analysis of “the essential tension between tradition and innovation” Thomas S. Kuhn focused on the apparent paradox that, on the one hand, normal research is a highly convergent activity based upon a settled consensus, but, on the other hand, the ultimate effect of this tradition-bound work has invariably been to change the tradition. Kuhn argued that, on the one hand, without the possibility of divergent thought, fundamental innovation would be precluded. On the other hand, without a strong emphasis (...) on convergent thought, science would become a mess created by continuous theory changes and scientific progress would again be precluded. On Kuhn’s view, both convergent and divergent thought are therefore equally necessary for the progress of science. In this paper, I shall argue that a similar fundamental tension exists between the demands we see for novel insights of an interdisciplinary nature and the need for established intellectual doctrines founded in the classical disciplines. First, I shall revisit Kuhn’s analysis of the essential tension between tradition and innovation. Next, I shall argue that the tension inherent in interdisciplinary research between, on the one hand, intellectual independence and critical scrutiny and, on the other hand, epistemic dependence and trust is a complement to Kuhn’s essential tension within mono-disciplinary science between convergent and divergent thought.

This chapter offers a overview of Shadworth Hodgson's account of experience as fundamentally temporal, an account that was deeply influential on thinkers such as William James and which prefigures the phenomenology of Husserl in many ways. I highlight eight key features that are characteristic of Hodgson's account, and how they hang together to provide a coherent overall picture of experience and knowledge. Hodgson's account is then compared to Husserl's, and I argue that Hodgson's account offers a better target for projects (...) such as neurophenomenology than does Husserl's. Hodgson's account is historically important as a culmination of a certain trajectory of British Empiricist thought. It offers a substantive alternative for how to think about temporality and experience in contemporary discussions, not just of the present moment but of the relationship between experience and knowledge more broadly.

This chapter discusses several kinds of reduction that are often found in the biomedical sciences, in contrast to reduction in fields such as physics. This includes reduction as a methodological assumption for how to investigate phenomena like complex diseases, and reduction as a conceptual tool for relating distinct models of the same phenomenon. The case of Parkinson’s disease illustrates a wide variety of ways in which reductionism is an important tool in medicine.

I present three reasons why philosophers of science should be more concerned about violations of causal faithfulness (CF). In complex evolved systems, mechanisms for maintaining various equilibrium states are highly likely to violate CF. Even when such systems do not precisely violate CF, they may nevertheless generate precisely the same problems for inferring causal structure from probabilistic relationships in data as do genuine CF-violations. Thus, potential CF-violations are particularly germane to experimental science when we rely on probabilistic information to uncover (...) the DAG, rather than already knowing the DAG from which we could predict the right experiments to ‘catch out’ the hidden causal relationships.

The overall aim of this article is to reorient the contemporary debate about epistemic consequentialism. Thus far the debate has to a large extent focused on whether standard theories of epistemic justification are consequentialist in nature and therefore vulnerable to certain trade-off cases where accepting a false or unjustified belief leads to good epistemic outcomes. We claim that these trade-offs raise an important—yet somewhat neglected—issue about the epistemic demands on inquiry. We first distinguish between two different kinds of epistemic evaluation, (...) viz., backing evaluation and outcome evaluation, and then go on to outline and discuss a consequentialist metatheory about the right combinations of decision procedures to adopt in inquiry. Note that the piece is exploratory in the following sense: we try to explore epistemic evaluation in consequentialist terms, which involves stating a form of epistemic consequentialism, but also pointing to what non-consequentialist alternatives might be. Rather than trying to argue decisively for a particular conclusion, we aim to outline various intricate issues in an underexplored area of theorizing. In the course of doing this, we’ll transpose some well-known themes from discussions of consequentialism in ethics to the current debate about consequentialism in epistemology, e.g., agent-neutrality, options, and side-constraints.

This chapter examines the philosophical discussion concerning the relationship between time, memory, attention, and consciousness, from Locke through the Scottish Common Sense tradition, in terms of its influence on James' development of the specious present doctrine. The specious present doctrine is the view that the present moment in experience is non punctate, but instead comprises some nonzero amount of time; it contrasts with the mathematical view of the present, in which the divide between past and future is merely a point (...) or a line with no thickness. The anonymous source for the term 'specious present' is revealed as a retired businessman-turned-amateur philosopher. The more likely source for the idea itself is a little-known philosopher, Shadworth Hollway Hodgson, who was not merely a significant influence on James but also on Husserl's development of the tripartite account of internal time consciousness. I conclude by demonstrating how James' changing views on the relationship between concepts and experience meant that by the later period of his writings, including those in which he develops his own views on pragmatism, James would have not merely noted the contrast between a mathematical conception of the present and our actual experience of it, he would have taken a further step and condoned the thick experience of the present as demonstrating the inadequacy of the intellectualized mathematical characterization.

This paper aims to show that Selim Berker’s widely discussed prime number case is merely an instance of the well-known generality problem for process reliabilism and thus arguably not as interesting a case as one might have thought. Initially, Berker’s case is introduced and interpreted. Then the most recent response to the case from the literature is presented. Eventually, it is argued that Berker’s case is nothing but a straightforward consequence of the generality problem, i.e., the problematic aspect of the (...) case for process reliabilism (if any) is already captured by the generality problem.
