Understanding women's work along the paid-underpaid-unpaid continuum presents a more holistic conceptualisation of women's work, recognising work burdens across the spheres of production and reproduction. This paper takes recourse to unit-level data from India Time-Use Survey (2019) to demonstrate the women's work continuum, highlighting the uneven burden of unpaid household work on women across varied employment categories and economic activities. Controlling for other confounders, women from marginalised castes and lower income groups are more likely to undertake unpaid activities. Further, marital status and location (rural-urban) are also crucial factors in determining the probability of women undertaking unpaid work and time spent on different activities. Therefore, it is imperative to recognise and understand women's work through the lens of the continuum and intersectionality. [ABSTRACT FROM AUTHOR]

El objetivo de la investigación realizada fue determinar la efectividad del método continuo frente al método interválico para optimizar la resistencia cardiorrespiratoria, se estableció la capacidad de resistencia de todos los participantes mediante la cuantificación de su Vo2 máxima a través de pruebas específicas como el test de Cooper y el test de Coursenavette, mismos que se aplicaron en un pre test a los dos grupos de prueba, posterior a esto se realizó una panificación e intervención de sesiones estructuradas de entrenamiento continuo (Grupo 1) y Entrenamiento Interválico (Grupo 2) y al finalizar la intervención se realizó un post test a los dos grupos. Los dos grupos de estudio mostraron mejoría en su vo2 máxima lo que demuestra un desarrollo positivo en su capacidad de resistencia cardiorrespiratoria, sin embargo, el método interválico presentó mejores resultados en la optimización de la resistencia. Basado en los resultados obtenidos en el estudio se concluye que tanto el método continuo como el método interválico evidenciaron una mejora en la capacidad cardiorrespiratoria, sin embargo, el método interválico revela una diferencia significativa superior ante el método continuo ya que los participantes que fueron intervenidos con el método de entrenamiento interválico presentaron una mejor captación máxima de oxígeno en los test de Cooper y Coursenavette.

RESUMO O objetivo deste artigo é analisar as relações entre infinito e número na filosofia de Espinosa. Para tanto, a análise iniciará se debruçando sobre a Carta 12 e distinguindo as noções de infinito em ato, indefinido, ilimitado e não enumerável. Nesse momento, buscar-se-á evidenciar em que medida as noções citadas diferem entre si, e porque não podem ser confundidas. Ao tratar da noção de número e de grandezas não enumeráveis, a análise focará no exemplo dos círculos não concêntricos, oferecido por Espinosa, e evidenciará que, além do contínuo, o que está em jogo no exemplo citado é aquilo que posteriormente viria a ser conhecido como números irracionais. Em seguida, tratar-se-á da noção de entes de razão e mostrar-se-á em que medida o tempo, a medida e o número diferem enquanto entes de razão. Feito isso, o artigo se encerra evidenciando que (i) é o número que depende do infinito para ser concebido, e não o inverso; e que (ii) a lição legada por Espinosa abre caminho para uma nova maneira de pensar o infinito, que será explorada por Cantor.

El propósito de este artículo es explorar la idea de que, aun cuando la Ceroidad fue acuñada por Deleuze y no por Peirce, no hay ningún problema en considerarla como el antecedente formal de la Primeridad. La argumentación mostrará que, sin la Ceroidad, Dios no habría podido transformar la nada en el conjunto vacío y, por tanto, no habría podido crear los elementos de la Primeridad. Esto puede ilustrarse con un experimento mental, en el que se hace evidente que, sin el conjunto vacío, no habrían surgido los continuos de la luminosidad y la coloreidad. Es decir, sin la Ceroidad del conjunto vacío, todo intento de crear los colores habría quedado absorbido en el caos de la nada.

En este artículo consideramos H(X) un hiperespacio de un continuo X. Sea f : X → Y una función continua entre continuos, se considera a la función inducida H(f) : H(X) → H(Y ) dada por H(f)(A) = f(A), para todo A ϵ H(X). Por otro lado, si tenemos a la función continua H : H(X) → H(Y) y existe g : X → Y tal que H = H(f), decimos que H es inducible. Se presentan tres clases de funciones entre continuos y se estudia el siguiente problema: f pertenece a una clase si y sólo si la función inducida H(f) también pertenece a esa clase. Además, se presenta una caracterización para las funciones inducibles y con esto se muestra una aplicación a encajes ordenados.

In this study, the production of fatty acid ethyl esters (FAEE) from macauba pulp oil and pressurized ethanol was investigated. The experiments were conducted without the addition of catalyst, at 20 MPa, to determine the effect of temperature (200 to 300 °C) and the oil to ethanol mass ratio (1:1 and 1:2) on the FAEE content and different residence times (10 to 45 min). The effect of the addition of n-hexane to the oil (20 wt%) as a co-solvent was also evaluated. The use of high temperatures (275 and 300 °C) resulted in high FAEE content (~90%). Increasing the amount of ethanol in the reaction medium contributed to the formation of esters only at operating temperatures of 200 to 250 °C. It was also observed that with the addition of co-solvent (in the oil) it was possible to obtain high amounts of FAEE in a shorter reaction time. In addition, a low content of unreacted compounds (~8.0%) and the conversion of ~90 and 99% of the free fatty acids and triglycerides were observed, respectively. [ABSTRACT FROM AUTHOR]

Dados dos hiperespacios fijos H(X) y H(Y ) de continuos métricos X y Y , respectivamente, una función continua g : H(X) → H(Y ) es inducible si existe una función continua f : X → Y tal que g(A) = {f(a) : a ∈ A}, para cada A ∈ H(X). En este trabajo presentamos una caracterización de funciones inducibles entre hiperespacios, la comparamos con las condiciones necesarias y suficientes bajo las cuales una función continua entre hiperespacios es inducible, dada por J.J. Charatonik y W.J. Charatonik en 1998, y damos ejemplos que muestran la independencia entre las condiciones en ambas caracterizaciones en todos los hiperespacios, algunos de ellos no habían sido considerados en la caracterización ya conocida, haciendo completo el estudio de esta clase de funciones continuas.

This systematic review shows the most important characteristics of the methods used for the production of polyhydrox yalkanoates (PHAs). Three databases were consulted: Science Direct, Scopus, and Google Scholar. A total of 66 publications were obtained. Cupriavidus necator was found to be the microorganism that generates more interest in the scientific community and the most tested one in different substrates, however, the highest productivity was reported in A zohydromonas lata, a low reported microorganism. The most common cultivation system was the fed-batch, easily used at the industrial level, although the continuous system could save time and potentially increase productivity. However, the type of substrate, the polymer to be produced and the metabolic characteristics and requirements of each microorganism, imply technical limitations, which are evidenced in this review in order to provide a better understanding about its advantages and disadvantages.

In this paper, I use Rameau's contradictions as a basis for my defense of the règle de l'octave. I also challenge certain misconceptions about the règle in current scholarly literature, notably its alleged harmonic incompleteness and stepwise motion requirement, while asserting some of its rarely discussed uses and properties.

Un espacio topológico conexo Z es unicoherente si para cualesquiera A y B cerrados y conexos de Z, tales que Z = A ∪ B, se tiene que A ∩ B es conexa. Sea Z un espacio unicoherente: decimos que z ∈ Z agujera a Z si Z − {z} no es unicoherente. Un problema de reciente estudio es: dado un espacio topológico unicoherente H(Z), obtenido de un espacio topológico Z, ¿cuáles elementos A ∈ H(Z) lo agujerean? Este trabajo consiste en dar una reseña de los resultados que hasta la fecha se conocen de este problema.

This article confronts the dialectic between parsimonious voice leading, as represented by neo-Riemannian theory, and the diatonic Stimmführungsmodelle, or the traditional formulas and methods of thorough-bass pedagogy as they were preserved in the nineteenth century. The historical contexts are represented by Carl Friedrich Weitzmann's essay on the augmented triad (1853) and Simon Sechter's Generalbass-Schule (1835). The possibility of setting the diatonic and chromatic models into productive analytic practice is explored, even as it is acknowledged that they are grounded in different principles. Steven Rings's "syntactical interaction"and Richard Cohn's "double syntax"are invoked. A Brahms song and a Schubert symphony serve as extended analytical examples. [ABSTRACT FROM AUTHOR]

This article focuses on the interpretation of the fundamental bass in terms of structural modes. The aim is to develop an analytical interpretation that relates tonality and tonal form to the fundamental bass. The approach is anchored in the Ramellian tradition by considering the fundamental bass as an autonomous level of analysis. A contiguity principle is governed by the modes of the musical tetractys, or structural modes: P4-M2-P4 (first mode), M2-P4-P4 (second mode), and P4-P4-M2 (third mode). These modes consist of three-scale degrees, which are labeled tonic, subdominant, or dominant, respectively, thus creating a conceptual bridge between scale theory and functional harmony. The dialogue between fundamental bass and real bass reflects a broader dialogue between a structural approach to fundamental bass and elements from thoroughbass and partimento traditions.

The Creative Problem Solving theory analyzes the main steps of a creative process: problem identification and delineation, information gathering, idea generation, its evaluation, refinement, implementation, and verification. Based on the findings of this theory, the present study aims at highlighting that not only artists and composers perform their tasks in a creative way, but also professionals doing jobs which are considered as not particularly creative. This study focuses in particular on continuo players and investment lawyers, stressing the often-overlooked creative elements of these jobs. The paper's conclusions highlight the individual and social returns of promoting creativity [ABSTRACT FROM AUTHOR]

El tratado hidrostático fue uno de los primeros textos de Descartes, fruto de su decisivo encuentro con Isaac Beeckman. En este artículo, analizaremos cómo fue concebido y los motivos que llevaron a Descartes a cuestionar alguno de los aspectos fundamentales de la física matemática de Beeckman. Este episodio está íntimamente relacionado con la independencia de las disciplinas matemáticas y su aplicación a cuestiones propias de la filosofía natural.

Alejandro Illanes preguntó si el pseudoarco P tiene hiperespacio segundo producto simétrico F2(P) único, es decir: si X es un continuo para el cual existe un homeomorsmo h : F2(P) → F2(X), entonces, ¿es X homeomorfo al pseudoarco? En este trabajo probamos que si X es un continuo indescomponible y encadenable y Y es un continuo tal que F2(Y ) es homeomorfo a F2(X), entonces Y es indescomponible. Para citar este artículo: M. de J. López, E. Ramírez Márquez, Sobre el segundo producto simétrico de continuos indescomponibles y en adenables, Rev. Integr. Temas Mat. 34 (2016), No. 2, 139-146.

The joint interpretation of phenology and nutritional metabolism provides important data on plant tissues reactivity and the period of gall induction. A population of Aspidosperma macrocarpon Apocynaceae with leaf galls induced by a Pseudophacopteron sp. Psylloidea was studied in Goiás state, Brazil. Assuming the morphological similarity between host leaves and intralaminar galls, a gradient from non-galled leaves towards galls should be generated, establishing a morpho-physiological continuum. The phenology, infestation of galls, and the carbohydrate and nitrogen contents were monthly evaluated in 10-20 individuals, from September 2009 to September 2010. Our objective was to analyze the nutritional status and the establishment of a physiological continuum between the galls and the non-galled leaves of A. macrocarpon. The period of leaf flushing coincided with the highest levels of nitrogen allocated to the new leaves, and to the lowest levels of carbohydrates. The nutrients were previously consumed by the growing leaves, by the time of gall induction. The levels of carbohydrates were higher in galls than in non-galled leaves in time-based analyses, which indicateed their potential sink functionality. The leaves were infested in October, galls developed along the year, and gall senescence took place from March to September, together with host leaves. This first senescent leaves caused insect mortality. The higher availability of nutrients at the moment of gall induction was demonstrated and seems to be important not only for the establishment of the galling insect but also for the responsiveness of the host plant tissues.

Se dice que una función f : X → Y definida entre espacios topológicos es conexa si la gráfica Γ(f) = {(x, f(x)) : x ∈ X} es conexa. Dado un continuo X, se consideran los hiperespacios: 2 X, la colección de todos los subconjuntos cerrados no vacíos de X; C(X), el conjunto de todos los subcontinuos de X; y Fn(X), los subconjuntos no vacíos de a lo más n puntos de X. Además, dada una función f : X → Y entre continuos, consideramos las funciones inducidas 2 f : 2X → 2 Y definidas por 2 f (A) = f(A) para cada A ∈ 2 X; Fn(f): Fn(X) → Fn(Y ), la función restricción Fn(f) = 2f |Fn(X) ; y si f es una función de Darboux débil, definimos C(f): C(X) → C(Y ) por C(f) = 2f |C(X) . En este artículo estudiamos las relaciones entre las siguientes cinco afirmaciones: 1) f es conexa; 2) C(f) es conexa; 3) Fn(f) es conexa, para algún n ≥ 2; 4) Fn(f) es conexa, para todo n ≥ 2; 5) 2 f es conexa. Abstract. A function between topological spaces f : X → Y is said to be connected provided that the graph Γ(f) = {(x, f(x)) : x ∈ X} is connected. Given a continuum X, some hyperspaces are considered: 2 X, the collection of all non-empty closed subsets of X; C(X), the set of all subcontinua of X, and Fn(X) the set of nonempty subsets of at most n points of X. Moreover, given f : X → Y a function between continua, consider the induced functions: 2 f : 2X → 2 Y , defined by 2 f (A) = f(A) for each A ∈ 2 X; Fn(f): Fn(X) → Fn(Y ), the restriction function Fn(f) = 2f |Fn(X) ; and, if f is a weak Darboux function, we define C(f): C(X) → C(Y ) by C(f) = 2f |C(X) . In this paper we study the relationships between the following five statements: 1) f is connected; 2) C(f) is connected; 3) Fn(f) is connected, for some n ≥ 2; 4) Fn(f) is connected, for all n ≥ 2; 5) 2 f is connected.

The manuscript of Striggio's Mass Ecco sí beato giorno for 40 and 60 voices is a fascinating bibliographical object, the dating of which has always been problematic. From the 18th century with Sébastien de Brossard, to the present day with Laurent Guillo and, more recently, Davitt Moroney, several hypotheses have been proposed for the date of this unicum, copied in France during the 17th century. This article presents new evidence based on the identification of three watermarks, whose concomitant presence allows dating the manuscript to the decade of 1610. The accurate dating of this manuscript is important not only for the reception of Striggio's music in 17thcentury France, but also because it may represent the first occurrence of the term 'basse continue'-or rather 'basse continuée'-in a French source. Furthermore, the manuscript bears strong evidence that it was the copyist who devised the 'basse continuée' part, and that he achieved this solely based on the vocal parts, and not from any pre-existent Italian basso seguente. Indeed, the analysis of the two organ parts reveals the challenging and laborious process the French copyist undertook to reach his goal. [ABSTRACT FROM AUTHOR]

In a recent study by Robin A. Leaver, the Sibley Choralbuch (Rochester, NY) was re-identified as likely stemming from J. S. Bach's students in Dresden from around 1730-40 (2016). The manuscript contains 227 figured-bass chorales--melodies with single figured basses--and thus matches the first part of C. P. E. Bach's description of his father's teaching method, where students first received a figured-bass chorale and added two inner voices. Later, students composed their own basses and figures. Here, the plural "basses" is significant, because several "multiple-bass" chorale sources have also come to light in recent years, many stemming from J. S. Bach's students, Kittel and Kirnberger, who discuss this technique in their treatises. These sources suggest that a little-known, keyboard chorale tradition also played an important role in Bach's pedagogy. The present article attempts to reconstruct this pedagogical process using contemporaneous German sources. [ABSTRACT FROM AUTHOR]

The present paper aims at accounting for the Spanish Imperfecto, Perfecto, Pluscuamperfecto and the Indefinido by applying three binary tense oppositions: Present vs Past, Synchronous vs Posterior and Imperfect(ive) vs Perfect(ive). For the sixteen Spanish tense forms under analysis a binary approach leads to covering twelve of them. Their relation with the preterital forms outside the range of the three oppositions is accounted for by two surgical operations: (a) the notion of Imperfect(ive) is severed from the notion of ongoing progress by restricting it to underinformation about completion and by seeing continuous tense forms as involving a more complex semantics; (b) the notion of (non-)stative is strictly severed from interference of information coming from the arguments of a verb. These theoretical moves make the way free for a formal-semantic insight into the interaction of Spanish tense and aspect. It also paves the way for a principled distinction between completion and anteriority. Restricted to tense forms pertaining to the past, our analysis sheds light on the struggle for survival of tense forms outside the binary system. [ABSTRACT FROM AUTHOR]
