Resumo: No texto A necessidade metafísica do homem, Schopenhauer elabora considerações fundamentais sobre sua metafísica imanente e, na ânsia de explicar por que o homem filosofa, alia-se a uma longa tradição de pensadores que viram na admiração o impulso metafísico do homem. Ele reinterpreta as duas mais famosas sentenças sobre o tema consoante o tom de sua filosofia. A origem da filosofia torna-se o resultado de fatores como a separação entre vontade e intelecto e a constatação de que o mundo, (...) tal como agora é, possui caráter contingente e poderia deixar de ser. A isso se unem a contemplação dos males do mundo e a consciência da finitude humana. No fim, desse conjunto emergem os sistemas metafísicos e religiosos. Este artigo comenta detidamente essas ideias, mostra sua relação com os filósofos antigos através de cinco tópoi e, ao fim, tenta localizar a originalidade da concepção schopenhaueriana, a qual se baseia na reinterpretação do primeiro tópos.: In the text entitled On man’s need of metaphysics, Schopenhauer makes important remarks on his immanent metaphysics and, trying to explain why men philosophize, joins a long tradition of thinkers who see in admiration man’s real metaphysical impulse. He reinterprets then the two most famous statements on this subject in accordance with the tone of his philosophy. The origin of philosophy becomes the result of phenomena such as the separation between will and intellect and the perception that this world, which currently is, could just as well not be. The contemplation of the world’s misfortunes and the consciousness of human finitude is also dealt with. Metaphysical and religious systems emerge from these factors. This paper discusses in detail these ideas and analyzes their relationship with the ancient philosophers and the five tópoi. It also seeks to discover the originality of Schopenhauer’s conception, which is based on the reinterpretation of the first topos. (shrink)

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

Discuto neste artigo o fragmento de Protágoras sobre a existência dos deuses e a sua coerência teórica com outras teses do sofista. Primeiramente, utilizo dados históricos e biográficos para iluminar o subjetivismo da primeira linha do fragmento. Em seguida, discuto os obstáculos epistemológicos mencionados por Protágoras e sugiro uma nova tradução para o termo brachýs, um dos conceitos centrais que ele propõe. Na seção 2, analiso o ataque à transcendência que distingue suas ideias sobre a matemática e a percepção sensível. (...) Finalmente, na seção 3, mostro como a sua postura teológica está de acordo com a tese do homo-mensura e com a sua abordagem antilógica. A conclusão ressalta a unidade do pensamento de Protágoras e a sua posição no Iluminismo grego. (shrink)

Zwischen 1738 und 1745 erschien in Amsterdam eine von Johann Christoph von Sprögel und Adolph Friedrich Marci übersetzte achtzehnbändige Ausgabe der Lehrbücher der Mathematik und Philosophic von Christian Wolff. 1764 gab Johannes Petsch, einer der bedeutendsten Leibniz-Wolffianer in den Niederlanden, eine holländische Übersetzung der Essais de Théodicée von Leibniz heraus. Wie groß jedoch der Einfluß der beiden deutschen Denker auf die niederländische Philosophie gewesen ist, war bislang unklar. Der Aufsatz versucht zu zeigen, daß der Leibniz-Wolffianismus neben dem Neukantianismus eine wichtige (...) Rolle im philosophischen Denken der Niederländer in der Zeit der Aufklärung spielte.

The second edition of this book on the problem of truth and the idea of semantics is an unchanged reprint of a volume originally published in 1957. While it is formally organized into twelve chapters, it effectively falls into three parts of which the first two primarily deal with the theories of A. Tarski and R. Carnap. Aside from a brief chapter on "Semantics, Quantification Theory and Metamathematics," the final part consists of a chapter, which the author entitles "Epistemological-Theoretical Discussion (...) of Semantic Concepts." In this the longest, and for anybody acquainted with the theories of Tarski and Carnap, probably most valuable chapter of the book, Stegmüller deals with a dozen objections to the semantic conception of truth, the importance of semantic concepts for various disciplines, including logic, mathematics, epistemology, and the empirical sciences, with the interrelation between semantic linguistic analysis and Wittgensteinian ideas, and finally with Quine's criticism of the analytic--synthetic distinction and certain aspects of the ensuing discussion up to the time of the book's original publication. To ascertain the author's current ideas about many of the topics with which he deals, it is obviously necessary to turn to his more recent writings. This book stands as an example of its author's incomparable clarity of critical exposition.--R. F. M. (shrink)

A cross-cultural survey experiment revealed a dominant tendency to rely on a rule’s letter over its spirit when deciding which behaviors violate the rule. This tendency varied markedly across (k = 15) countries, owing to variation in the impact of moral appraisals on judgments of rule violation. Compared with laypeople, legal experts were more inclined to disregard their moral evaluations of the acts altogether and consequently exhibited stronger textualist tendencies. Finally, we evaluated a plausible mechanism for the emergence of textualism: (...) in a two-player coordination game, incentives to coordinate in the absence of communication reinforced participants’ adherence to rules’ literal meaning. Together, these studies (total n = 5,794) help clarify the origins and allure of textualism, especially in the law. Within heterogeneous communities in which members diverge in their moral appraisals involving a rule’s purpose, the rule’s literal meaning provides a clear focal point—an identifiable point of agreement enabling coordinated interpretation among citizens, lawmakers, and judges.

This paper aims to introduce a robust framework for forecasting demand, including data preprocessing, data transformation and standardization, feature selection, cross-validation, and regression ensemble framework. Bagging ), boosting and extreme gradient boosting regression ), and stacking are employed as ensemble models. Different machine learning approaches, including support vector regression, extreme learning machine, and multilayer perceptron neural network, are adopted as reference models. In order to maximize the determination coefficient value and reduce the root mean square error, hyperparameters are set using (...) the grid search method. Using a steel industry dataset, all tests are carried out under identical experimental conditions. In this context, STACK1 and STACK2 models provided better performance than other models. The highest accuracies of R2 of 0.97 and 0.97 are obtained using STACK1 and STACK2, respectively. Moreover, the rank according to performances is STACK1, STACK2, XGBR, GBR, RFR, MLP, ELM, and SVR. As it improves the performance of models and reduces the risk of decision-making, the ensemble method can be used to forecast the demand in a steel industry one month ahead. (shrink)

Our goal was to explore self‐care practices among men who have sex with men in the context of Mpox in Brazil. This study used qualitative research methods, including interviews and thematic analysis, to collect and analyze data from male participants across the Brazilian territory. The narratives unveil men's perspectives on self‐care, risk reduction, and health beliefs during the Mpox pandemic. Our findings highlight a multifaceted approach to self‐care among men, encompassing hygiene, physical contact management, mask usage, skin lesion vigilance, and (...) adherence to official guidelines. Men's attitudes toward sexual behaviors emphasize the importance of reducing sexual partners, practicing safe sex, and combating misinformation through accurate information dissemination. The development of these behaviors and self‐care practices can be facilitated by nurses guided by Dorothea Orem's Self‐Care Theory, supported by patient‐centered care, with strategies to address and confront the stigma associated with the disease and provide emotional support. Thus, the study underscores the pivotal role of self‐care in mitigating infection risks, especially in the context of emerging infectious diseases. It acknowledges the impact of socio‐cultural factors and healthcare policies on men's preventive measures. However, it also recognizes limitations, such as potential bias due to stigma concerns and a nonrepresentative sample. Ultimately, the research advocates for tailored education, promotion of gender equity, and healthcare empowerment to effectively manage health risks in such contexts. (shrink)

A obra Consequências da liberdade, publicada no ano de 2011 pela Editora Universitária da UFPE, é primeira obra do escritor e filósofo Geraldo Euclides da Silva, e que certamente se firmará no cenário de exegese das pesquisas sobre o pensamento existencialista de corte sartreano.

8 March, now known as International Women’s Day, is a day for feminist claims where demonstrations are organized in over 150 countries, with the participation of millions of women all around the world. These demonstrations can be viewed as collective rituals and thus focus attention on the processes that facilitate different psychosocial effects. This work aims to explore the mechanisms involved in participation in the demonstrations of 8 March 2020, collective and ritualized feminist actions, and their correlates associated with personal (...) well-being and collective well-being, collective efficacy and collective growth, and behavioral intention to support the fight for women’s rights. To this end, a cross-cultural study was conducted with the participation of 2,854 people from countries in Latin America and Europe, with a retrospective correlational cross-sectional design and a convenience sample. Participants were divided between demonstration participants and non-demonstrators or followers who monitored participants through the media and social networks. Compared with non-demonstrators and with males, female and non-binary gender respondents had greater scores in mechanisms and criterion variables. Further random-effects model meta-analyses revealed that the perceived emotional synchrony was consistently associated with more proximal mechanisms, as well as with criterion variables. Finally, sequential moderation analyses showed that proposed mechanisms successfully mediated the effects of participation on every criterion variable. These results indicate that participation in 8M marches and demonstrations can be analyzed through the literature on collective rituals. As such, collective participation implies positive outcomes both individually and collectively, which are further reinforced through key psychological mechanisms, in line with a Durkheimian approach to collective rituals.

Ortadoğu bölgesindeki çatışma ve istikrarsızlık ortamının ardında İran - Suudi Arabistan rekabeti bulunmaktadır. Bununla birlikte bu rekabetin politik doğası, çoğunlukla ana akım medya tarafından aşırı derecede basitleştirilmiştir. Benzer biçimde İran – Suudi Arabistan rekabetinin içindeki kimlik politikaları üzerine yazılmış literatürün büyük bir kısmı bölgesel istikrarsızlıkların kökeni ve kaynağını ağırlıklı olarak tarihlerinin genel ve betimleyici bir hesabını sunmuş veya oyuncuların iktidar mücadeleleri içerisinde Sünni ve Şii İslam’ın politikleşmesine ve manipülasyonuna odaklanmıştır. Halen mevcut olan kimlik politikaları üzerine teorileri sentezleyen, yani Primordializm, araçsallık, (...) ve sosyal inşacılık, bu araştırmanın teorik modelini oluşturmaktadır. Bu modelde, mezhepsel kimlik – Ortadoğu toplumlarının ve yanı sıra bölgesel tarihin bir gerçeği olarak – sadece politik süreçler üzerine muazzam etkileri ölçülmedi, ayrıca politik uygulamalarda her düzeydeki politik aktörlerin kullanımıyla karşılaştırılmıştır.

The solution of the outer multiplicity problem in the tensor product of U(3) irreducible representations (irreps) developed by Biedenharn et al.(1–7) and realized through the well-known Draayer-Akiyama (DA) computer code(8) is extended to the quantum algebra Uq(3). An analytic formula for special stretched Uq(3) Wigner coefficients, $$\left\langle {(\lambda _1 \mu _1 ) H_1 , (\lambda _2 \mu _2 ) \varepsilon _2 \Lambda _2 m_2 \left| { (\lambda _3 \mu _3 ) H_3 } \right.} \right\rangle _{\max }^q $$ is derived using (...) a projection operator method.(9–10) In this expression Hi denotes the highest weight vector of the (λiμi) irrep; the subscript “max” means coefficients corresponding to a unit tensor operator with a maximal characteristic null space; and q is the usual quantum label so the standard U(3) Wigner coefficient, which is required in the DA code, can be obtained in the q→1 limit of the theory. To illustrate the theory, some Uq(3) Wigner coefficients for the tensor product (22)×(22) are calculated. The procedure for evaluating nonhighest weight Wigner Uq(3) coefficients follow the DA prescription. (shrink)

Purpose: Performance measurement systems (PMS) in Nonprofit Organizations (NPOs) are more complex than in for-profit organizations. NPOs have an orientation towards social mission and values, and they consider not only organizational efficiency and viability, but also the social impact of the organization. This research provides a comprehensive synthesis of PMSs in NPOs. Design/methodology/approach: Using a literature review, supported by bibliometric and network analyses. A paper set of 240 articles related to this research field is examined. Topics that are the most (...) prevalent in this research area and their interrelationships are identified, presenting an outline of current efforts. Findings: Despite the descriptive analyses for the paper set, a framework is proposed for organizing the design-implementation factors of PMSs in nonprofit organizations, identifying the main requirements for their successful development. Originality/value: Investigation on performance measurement in nonprofit organizations is still in its early stages of development with many opportunities to further develop the field. Conceptual frameworks and models, as well as specific theories, are being generated for this field of research, and the process of adapting models from the general field of performance measurement is taking place. The meta-framework that organizes the main research topics of PMS in nonprofit organizations and the framework that consolidates factors that influence the design-implementation of PMSs in nonprofit organizations developed represents this paper contribution.

BackgroundResponsive neurostimulation has been utilized as a treatment for intractable epilepsy. The RNS System delivers stimulation in response to detected abnormal activity, via leads covering the seizure foci, in response to detections of predefined epileptiform activity with the goal of decreasing seizure frequency and severity. While thalamic leads are often implanted in combination with cortical strip leads, implantation and stimulation with bilateral thalamic leads alone is less common, and the ability to detect electrographic seizures using RNS System thalamic leads is (...) uncertain.ObjectiveThe present study retrospectively evaluated fourteen patients with RNS System depth leads implanted in the thalamus, with or without concomitant implantation of cortical strip leads, to determine the ability to detect electrographic seizures in the thalamus. Detailed patient presentations and lead trajectories were reviewed alongside electroencephalographic analyses.ResultsAnterior nucleus thalamic leads, whether bilateral or unilateral and combined with a cortical strip lead, successfully detected and terminated epileptiform activity, as demonstrated by Cases 2 and 3. Similarly, bilateral centromedian thalamic leads or a combination of one centromedian thalamic alongside a cortical strip lead also demonstrated the ability to detect electrographic seizures as seen in Cases 6 and 9. Bilateral pulvinar leads likewise produced reliable seizure detection in Patient 14. Detections of electrographic seizures in thalamic nuclei did not appear to be affected by whether the patient was pediatric or adult at the time of RNS System implantation. Sole thalamic leads paralleled the combination of thalamic and cortical strip leads in terms of preventing the propagation of electrographic seizures.ConclusionThalamic nuclei present a promising target for detection and stimulation via the RNS System for seizures with multifocal or generalized onsets. These areas provide a modifiable, reversible therapeutic option for patients who are not candidates for surgical resection or ablation. (shrink)
