Abstract
We present a dust spectral energy distribution (SED) and binary stellar population analysis revisiting the dust production rates (DPRs) in the winds of carbon-rich Wolf–Rayet (WC) binaries and their impact on galactic dust budgets. DustEM SED models of 19 Galactic WC “dustars” reveal DPRs of

We incorporated dust production into Binary Population and Spectral Synthesis (BPASS) models to analyze dust production rates from WC dustars, asymptotic giant branch stars (AGBs), red supergiants (RSGs), and core-collapse supernovae (SNe). BPASS models assuming constant star formation (SF) and a coeval 106

⊙ stellar population were performed at low, Large Magellanic Cloud (LMC)–like, and solar metallicities (Z = 0.001, 0.008, and 0.020). Both constant SF and coeval models indicate that SNe are net dust destroyers at all metallicities. Constant SF models at LMC-like metallicities show that AGB stars slightly outproduce WC binaries and RSGs by factors of 2–3, whereas at solar metallicities WC binaries are the dominant source of dust for ∼60 Myr until the onset of AGBs, which match the dust input of WC binaries. Coeval population models show that, for “bursty” SF, AGB stars dominate dust production at late times (t ≳ 70 Myr).

Abstract
The formation and evolution of binary stars are critical components of several fields in astronomy. The most numerous sources for gravitational wave observatories are inspiraling or merging compact binaries, while binary stars are present in nearly every electromagnetic survey regardless of the target population. Simulations of large binary populations serve to both predict and inform observations of electromagnetic and gravitational wave sources. Binary population synthesis is a tool that balances physical modeling with simulation speed to produce large binary populations on timescales of days. We present a community-developed binary population synthesis suite, COSMIC, which is designed to simulate compact-object binary populations and their progenitors. As a proof of concept, we simulate the Galactic population of compact binaries and their gravitational wave signals observable by the Laser Interferometer Space Antenna.

Abstract
General relativity is a fully conservative theory, but there exist other possible metric theories of gravity. We consider nonconservative ones with a parameterized post-Newtonian parameter, ζ

2 induces a self-acceleration for the center of mass of an eccentric binary pulsar system, which contributes to the second time derivative of the pulsar spin frequency,

En los últimos 20 años los estudios relacionados a la acreditación de las universidades y escuelas de negocios han sido escasos. Por otro lado, las investigaciones realizadas han sido liderados por países como: Estados Unidos, Canadá, India y Reino Unido. De tal forma que, en los países latinoamericanos no se hace énfasis en el impacto que tiene la acreditación de las universidades y escuelas de negocios sobre la sociedad; a pesar de que varios de estos países cuentan con instituciones de educación superior acreditadas. Dado aquello, el presente estudio tiene como objetivo argumentar sobre la importancia de la acreditación de las escuelas de negocio, considerando las dimensiones que aborda y su implicancia en la innovación, además de describir cuáles son sus factores claves de éxito, su principal impacto en la calidad educativa empresarial y los costos asociados. Se concluye que, en efecto, uno de los aportes de la acreditación en la educación empresarial es brindar profesionales altamente cualificados que promuevan el aprovechamiento de oportunidades de negocios en los diferentes mercados locales e internacionales.

<p>The present study was conducted during quarantine which was caused due to the pandemic of COVID-19 virus in Greece. We try to detect the immediate psychological effects of crisis conditions on university students, focusing on the symptoms of depression. The main goal is to evaluate the clinical depression that students present due to quarantine. The study participants were 570 students of the University of Patras, who completed an electronic questionnaire that includes demographic data and the BECK (BDI) depression scale, which measures the severity of depression. The results show that a significant percentage of participating students at the University of Patras reported increased symptoms of depression. Students' mental health seems to be significantly affected when situations of social constraint arise and, consequently, require attention and help. Critical, therefore, the role of the University is emerging in providing students adequate psychological services in order to strengthen and support them.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0653/a.php" alt="Hit counter" /></p>

As competências requeridas pelo mundo do trabalho em relação ao exercício da profissão de Contador vão além da formação técnica voltada para o controle e registros dos eventos econômicos e financeiros das entidades. O atual cenário da Contabilidade exige que esses profissionais tenham competências suficientes para gerenciar os empreendimentos. Entretanto, as metodologias utilizadas no Ensino Superior em Ciências Contábeis, principalmente aplicadas na disciplina Contabilidade de Custos, continuam centradas na figura do professor como sujeito preponderantemente ativo no processo de ensino-aprendizagem. Ao mesmo tempo que é preciso incluir metodologias que oportunizem desenvolver capacidade crítica, de análise, de reflexão, entre outras, sabe-se que esse processo de mudança é lento, pois demanda capacitação de docentes que, na maioria, não possuem dedicação exclusiva ao ensino, pois são profissionais da área, e poucos têm formação Stricto Sensu. Diante disso, o objetivo do artigo consiste em verificar possíveis reflexos no processo de aprendizagem dos estudantes mediante o uso de metodologias ativas no ensino da contabilidade de custos. A pesquisa classifica-se como descritiva, com análise qualitativa. Os resultados apontam que a metodologia ativa empregada contribuiu positivamente para o processo de ensino-aprendizagem, uma vez que os estudantes envolvidos nessa experiência mostraram maior interesse pela construção do conhecimento por meio da leitura, aplicação e discussão de conceitos ainda não vistos em sala de aula, o que fortalece a autonomia discente. Porém, o emprego de metodologias ativas merece cuidados para evitar sobrecarga de atividades aos professores e estudantes.

O acirramento da competição faz com que as empresas preocupem-se com a racionalização dos recursos aplicados na produção, busquem melhorar seus processos produtivos e a gestão das informações, visando aumentar a competitividade e expandir o seu mercado. As informações de custos podem auxiliar nesta tarefa, razão pela qual este trabalho discute a aplicação do método da unidade de esforço de produção (UEP) em uma empresa fabricante de cosméticos. Foi realizado um estudo de caso em uma empresa do Estado de Santa Catarina, na estruturação do método da UEP, envolvendo as cinco etapas da fase de implantação, que são concluídas com a determinação dos equivalentes dos produtos em UEP. A partir destes equivalentes faz-se a operacionalização do método para a produção do período subsequente ao da implantação, chegando-se ao custo de transformação de cada produto. Com o método, a empresa pode apurar mensalmente, de forma facilitada, o custo de transformação unitário dos produtos que fabrica, tendo assim informações que auxiliam no controle e tomada de decisões. O método da UEP facilita o processo de apuração de custos, sendo essa uma de suas grandes vantagens em relação aos demais métodos de custeio.

Abstract. Atmospheric aerosol particles are the precondition for the formation of cloud droplets and therefore have large influence on the microphysical and radiative properties of clouds. In this work, four different methods to derive or measure number concentrations of cloud condensation nuclei (CCN) were analyzed and compared for present-day aerosol conditions: (i) a model parameterization based on simulated particle concentrations, (ii) the same parameterization based on gravimetrical particle measurements, (iii) direct CCN measurements with a CCN counter, and (iv) lidar-derived and in situ measured vertical CCN profiles. In order to allow for sensitivity studies of the anthropogenic impact, a scenario to estimate the maximum CCN concentration under peak aerosol conditions of the mid-1980s in Europe was developed as well. In general, the simulations are in good agreement with the observations. At ground level, average values between 0.7 and 1.5×109 CCN m−3 at a supersaturation of 0.2 % were found with the different methods under present-day conditions. The discrimination of the chemical species revealed an almost equal contribution of ammonium sulfate and ammonium nitrate to the total number of CCN for present-day conditions. This was not the case for the peak aerosol scenario, in which it was assumed that no ammonium nitrate was formed while large amounts of sulfate were present, consuming all available ammonia during ammonium sulfate formation. The CCN number concentration at five different supersaturation values has been compared to the measurements. The discrepancies between model and in situ observations were lowest for the lowest (0.1 %) and highest supersaturations (0.7 %). For supersaturations between 0.3 % and 0.5 %, the model overestimated the potentially activated particle fraction by around 30 %. By comparing the simulation with observed profiles, the vertical distribution of the CCN concentration was found to be overestimated by up to a factor of 2 in the boundary layer. The analysis of the modern (year 2013) and the peak aerosol scenario (expected to be representative of the mid-1980s over Europe) resulted in a scaling factor, which was defined as the quotient of the average vertical profile of the peak aerosol and present-day CCN concentration. This factor was found to be around 2 close to the ground, increasing to around 3.5 between 2 and 5 km and approaching 1 (i.e., no difference between present-day and peak aerosol conditions) with further increasing height.
Sulla soglia: la narrativa di Maria Messina
Authors: Sapegno Maria Serena 
Published: July 2020

This article discusses all of Maria Messina's writings. It starts by positioning the author’s choices amidst the new potential subjects brought up by the rapid modernization process that took place in Italy at the beginning of the 20th century. Maria Messina seems to focus especially on the crisis of the patriarchal system and on the conflicting forms by which new emerging subjects, particularly women, express themselves. While she describes their painful movement towards an identity, and their scarcely successful paths that often end up in loneliness, Messina seems at the same time to endorse the idea that no step backward will be allowed, since the undisputed legitimization of the patriarchate was fissured and “the king is naked”. The definition of the subject’s identity are therefore the main object of this analysis, which reads Messina's works by focusing especially on recurring themes, such as family, emigration, representations of the patriarchate, father-daughter relationships, or the ways in which conscience and freedom relate to each other. One of the most important questions related to Messina's writing is if and to what degree this last idea – that is, that the acquisition of a conscience can possibly lead to an effective freedom – is articulated.
El problema del radicalismo cosmológico de Spinoza y Nietzsche: análisis desde dos lecturas nietzscheanas
Authors: Martínez Becerra Pablo 
Published: July 2020

Al intentar establecer cuánto debe Nietzsche a Spinoza en la configuración de su visión radical del mundo y quién de los dos da los pasos más decisivos en la disolución de la trascendencia, encontramos diversas dificultades. La primera es que la disputa acerca del ateísmo spinociano parece que no podrá nunca dirimirse en un grado aceptable. La segunda dice relación con la imagen que Nietzsche tiene de Spinoza en tanto puede considerarse sesgada debido al conocimiento indirecto de su obra. La tercera es que para determinar, en parte, qué adeuda la interpretación de Nietzsche al filósofo holandés, se requiere hacer un análisis exhaustivo y pormenorizado de sus autores fuente. Tomando en cuenta estas complejidades, el autor del artículo defiende que para formarse una idea adecuada de la deuda del radicalismo de Nietzsche con Spinoza y para juzgar quién de ellos nos precipita con más relevancia a la pura inmanencia, es necesario ir estudiando sus lecturas sobre el filósofo judío, incluso las más descuidadas, más allá de Kuno Fischer. De acuerdo con ello, en este escrito se analizan dos lecturas de Nietzsche poco utilizadas en esta reflexión, a saber: Heinrich Heine (1797-1856) y Jean-Marie Guyau (1854-1888). Se asume así que, para alcanzar un nivel más alto de claridad en el tema estudiado, se ha de acotar el marco bibliográfico en el que se ha de realizar la hermenéutica de Nietzsche y sus fuentes. Teniendo presente estos presupuestos, se compara el panteísmo, la desantropomorfización del mundo y el conatus sese conservandi de Spinoza, con el monismo, la extramoralidad del mundo y la voluntad de poder de Nietzsche, respectivamente, para evaluar el alcance del radicalismo cosmológico de uno y otro autor.
En busca de la democracia spinoziana
Authors: Rojas Lillo Salomé 
Published: July 2020

El objetivo de este escrito es exponer las características del Estado democrático como lo concibe Spinoza en su Tratado teológico político (1670), conciliando la libertad individual con la paz del Estado. Para esto, en primera instancia se contrastan los efectos de gobernar de forma autoritaria, liberal y democráticamente. Luego presento los fundamentos del Estado a partir del derecho natural individual y una ley universal humana para poder establecer los requisitos para que se conserve el Estado democrático: obediencia, fidelidad y libertad de expresión de parte de los súbditos, determinando los límites tanto de los individuos como de parte del Estado. Finalmente, se presenta la degeneración de la razón de Estado como la concibe Maquiavelo, dejando abierta la reflexión para lo que sucede en el ámbito de la política actual.
