The aim of the study was to examine how students generate problems about the concept of series, and how they evaluate and solve these problems. The difficulties experienced by the students while posing problems and their perceptions of the posing-evaluating-solving approach were also explored. In the first stage, 46 second-year university students posed problems for four tasks. In the second stage, which occurred a week after the first stage, the students evaluated their self-generated problems in terms of appropriateness to the tasks. The students who thought that they did not pose problems suitable for the tasks revised or reposed the problems, and then solved them by specifying the convergence or divergence of the series in the problems. The students also considered the impact of problem-posing implementation on their knowledge of the series. Findings showed that students' difficulties led to unsuitable and unsolvable problems. The most prominent difficulties were using sequences instead of series and using convergent series instead of divergent series or vice versa. Moreover, providing the students with opportunities to evaluate and solve their self-generated problems at the end of the second stage was effective for the increase in the number of suitable and solvable problems.

This article focuses on the role of female showrunners in Spain, from 2019 to the present. The main objective of the research is to examine whether female showrunners play the same role as their male counterparts, both quantitatively and qualitatively, and to identify their tasks, obstacles and leadership. The methodology is based on semi-structured interviews with five Spanish female showrunners. The conclusions point out that while men are involved in all the tasks, including the choice of the people in charge of the different technical areas or the equipment, the women interviewed are involved in the management functions that are more closely linked to the script.

This note presents an extension of a result within the concept of S -lineability, originally due to Bernal-González, Conejero, Murillo-Arcila, and Seoane-Sepúlveda. Additionally, we provide a characterization of lineability in the context of complements of unions of closed subspaces in F-spaces in terms of ℓ ∞ -lineability. We also present a negative result in both normed spaces and p-Banach spaces. These findings contribute to the understanding of linearity within exotic settings in vector spaces.

The Ratio Test and the Root Test for absolute convergence/divergence of series of numbers $ \sum _{n=0}^{\infty }a_n $ ∑n=0∞an are frequently discussed and proved independently in Calculus courses. The Root Test is stronger (verifies convergence for more series) than the Ratio Test. This relation inspires introduction of some intermediate strength tests (stronger than the Ratio Test and weaker than the Root Test) that we call Power Mean Tests (they, in particular, include the Arithmetic Mean Test). We show the connection between the Root, the Power Mean and the Ratio Tests. We also note that all these tests are related to the test that we formulate and call Generalised f-mean Test (or Kolmogorov–Nagumo–de Finetti mean Test). We provide an example of an infinite series, where the Arithmetic Mean test is the test that should be used for convergence verification, because the Root and the Ratio Tests are not easy to apply. We conclude this work with the statement emphasising why it is ‘fair’ to include the summarising Corollary 3.1 in our Calculus course. [ABSTRACT FROM AUTHOR]

The aim of this research was to map and classify some soils of coastal plain sands origin in Edo State, Nigeria. The study covered two areas, including Site A (4 hectares) and Site B (12 hectares). The methodology used was a systematic soil survey using a rigid grid at detailed scales (1:5000 for Site A and 1:10,000 for Site B), with two mapping units delineated at each site. A representative pedon was excavated in each mapping unit, described, and sampled for analysis. Soil samples were analyzed using standard laboratory methods, and the data were processed with descriptive statistics. Soil classification followed USDA soil taxonomy, the World Reference Base for Soil Resources, and local systems. The morphological properties showed reddish soil colors when moist, with structures varying from single grain crumb to sub-angular blocky, and textures from sand to sandy clay loam. The content of sand, silt, and clay ranged from =742.0 to =886.00 g/kg, from =15.00 to =26.00 g/kg, and from =88.00 to =190.00 g/kg, respectively. Meanwhile, pH, organic carbon, cation exchange capacity, and base saturation ranged from =5.24 to =5.58, from =4.80 to =13.70, from =6.71 to =11.90 cmol/kg, and from =9.80 to =21.60 cmol/kg, consecutively. Pedons 2A and 2B were classified as Rhodic kandiudults by USDA, Rhodic Nudiargic Acrisols (Arenic, Vetic) by WRB, and locally as the Orlu series. Pedon 1A was classified as Typic Udipsamments by USDA, Eutric Rhodic Arenosols (Transportic) by WRB, and locally as the Ahiara series. Pedon 1B was classified as Typic Eutrudepts by USDA, Eutric Rhodic Cambisols (Arenic, Ochric) by WRB, and locally as the Kulfo series. [ABSTRACT FROM AUTHOR]

This paper examines how multiseason drama serials, including those characterized as 'quality' or 'complex' television, deliver their continuation across multiple seasons. It proposes 'desperation' as a distinctive storytelling modality in which continuation itself and the narrative means by which continuation is managed are brought to the fore, charting how this is deployed by many shows which use season-long stories and/or stories which run for the lifetime of the show. Dramas derived from literary sources are examined alongside those where original narratives are drafted while they are already underway, and the relationship among continuation, seriality, adaptation, and literary/story-telling models is considered. Finally, through discussion of 'show bibles' and 'pitch bibles' it contends that continuing dramas effectively adapt themselves through the manner in which earlier seasons generate models and possibilities for those that follow.

This study examines the degree to which political alienation viewers consider themselves to have audiovisual productions. To understand the preferences of millennials and centennials in the Spanish-speaking world, a survey was conducted with 998 individuals from Spain and Mexico, two countries with high rates of OTT consumption. The survey revealed that young people feel justified in expressing their discontent with audiovisual productions on social media, potentially leading to an “audience dictatorship, “ which stifles creative freedom and expression. In this sense, young people with discursive power in social networks to change and censor production see it as plausible to use this channel as a denunciation or complaint.

La literatura occidental, de acuerdo con Harold Bloom, tiene un par de pilares: tanto las obras homéricas como la tradición judeocristiana, en específico, la recogida en la Biblia. Esta herencia es indeleble incluso en pleno siglo XXI. Al día de hoy, estamos inmersos en un mundo en el que las redes sociales son parte de nuestra cotidianidad, por esa razón, en este artículo me interesa mostrar tres series de minificciones que se encuentran en Museo de nimiedades (2022) de José Juan Aboytia, así como el tratamiento que este autor les da. Dichas series son las siguientes: lo bíblico, lo literario y las redes sociales. Aunque éstas no son las únicas que se hallan en el volumen, las destaco por los distintos elementos que aportan para el estudio de la minificción: la brevedad, el humor, el des-género que señala Violeta Rojo, la intertextualidad, la crítica social y las posibilidades de lectura que obligan al lector a ser un participante activo

Las series de televisión son uno de los formatos más consumidos por los jóvenes. Gracias a ellas, se transmiten enseñanzas a través de los contenidos que se muestran. El objetivo de este estudio es conocer las enseñanzas relacionadas con la filosofía en Merlí. Se ha elegido una metodología cualitativa, a través de un análisis de contenidos y el estudio de los personajes. Los resultados muestran cómo se acerca la filosofía a los adolescentes a través de los asuntos que a estos les interesa. Se concluye que las series educativas tienen un gran valor didáctico para la audiencia.

We derive a deterministic mathematical model that scrutinizes the dy-namics of cholera pathogen carriers and the hygiene consciousness of in-dividuals, before the illness, during its prevalence, and after the disease’s outbreaks. The dynamics can effectively help in curtailing the disease, but its effects had less coverage in the literature. Boundedness of the solu-tion of the model, its existence, and uniqueness are ascertained. Effects of cholera pathogen carriers and hygiene consciousness of individuals in controlling the disease or allowing its further spread are analyzed. The differential transformation method is used to obtain series solutions of the differential equations that make the system of the model. Simulations of the series solutions of the model are carried out and displayed in graphs. The dynamics of the concerned state variables and parameters in the model are interpreted via the obtained graphs. It is observed that higher hygiene consciousness of individuals can drastically reduce catching cholera disease at onset and further spread of its infections in the population, this in turn, shortens the period of cholera epidemic.

Modern mainstream financial theory is underpinned by the efficient market hypothesis, which posits the rapid incorporation of relevant information into asset pricing. Limited prior studies in the operational research literature have investigated tests designed for random number generators to check for these informational efficiencies. Treating binary daily returns as a hardware random number generator analogue, tests of overlapping permutations have indicated that these time series feature idiosyncratic recurrent patterns. Contrary to prior studies, we split our analysis into two streams at the annual and company level, and investigate longer-term efficiency over a larger time frame for Nasdaq-listed public companies to diminish the effects of trading noise and allow the market to realistically digest new information. Our results demonstrate that information efficiency varies across years and reflects large-scale market impacts such as financial crises. We also show the proximity to results of a well-tested pseudo-random number generator, discuss the distinction between theoretical and practical market efficiency, and find that the statistical qualification of stock-separated returns in support of the efficient market hypothesis is dependent on the driving factor of small inefficient subsets that skew market assessments.

Se parte de la importancia de los personajes en la construcción de la narrativa audiovisual seriada y la adhesión del público a través de la identificación y la conexión empática con los mismos, diferenciando sus aspectos cognitivos y emocionales. Seguidamente se expone el concepto de los nuevos malos de las series, como personajes complejos multideterminados, antihéroes humanizados, en contraposición con los estereotipados viejos malos de las películas. Se analiza el conflicto de las audiencias por mantener su adhesión a estos personajes, a medida que crecen sus miserias y presentan conductas contrarias a los estándares morales del espectador. Se propone la teoría sociocognitiva de la Desconexión Moral Selectiva como hipótesis explicativa de los procesos psicológicos operantes en la resolución la disonancia cognitiva operada en el espectador. Se mencionan y explican los ocho mecanismos válidos para justificar las conductas dañosas y se aplican, a modo de ejemplo, principalmente, a una escena paradigmática de la serie Breaking Bad.

Fourteen giants or groups of giants, anonymous or not, mythological figures or not, appear at the beginning of the Heroicus. The protagonist of the dialogue claims to prove, by relating the discovery of the skeletons of some, that the Homeric heroes were also of superhuman size. This series of examples weaves a complex textual network, exploiting the resources of variation, and also plays on the intertwining of the author’s life and literature, on intratextuality and intertextuality, blurring the border between person and character. Far from repetition, this enumeration deploys a text governed by the principle of poikilia and enhances, explicitly or implecitly, Heracles and Athens.

Renewable energy is in very much demand in current time due to its many favorable environment effect. Solar energy is one of the frontline sources of renewable energy. Solar photovoltaic converts the solar light into electricity. The performance of the solar photovoltaic depends on various parameters and one of such parameters is shading behavior. Further, the shading pattern and the progress of the shading are also important for predicting the solar performance. The interconnections of solar cells also impact the performance of solar photovoltaic. Therefore, a 4 × 4 module with various interconnections such as series-parallel (SP), total cross tied (TCT), bridge-link (BL), honeycomb (HC) and triple tied (TT) are studied under the row and column wise shading pattern. Shading pattern on a 4 × 4 module is increased cell by cell in horizontal direction, both from left to right and right to left. In the similar fashion, the shading pattern is varied from top to bottom or vice-versa in vertical direction. This shading pattern progresses from first row to the last and first column to last column in a progressive fashion. The power-voltage and current-voltage characteristics of solar photovoltaic are investigated for the mentioned shading patterns using various reconfigurations. The power output is identical when all cells in a row or column are shaded. On the other hand, if only few cells are shaded on row or column then the power output with TCT connection is highest among all connections. Further, the power output is for complete column shading is much higher than complete row shading for all the connections. The theoretical simulated results can ensure better implementation of interconnection in hardware set-up based on the shading pattern. [ABSTRACT FROM AUTHOR]

The sitcom How I Met Your Mother (2005–14) applies a narrative with a transmedia perspective, using advertising techniques that had been unusual for its genre up to that point. We refer to the reverse product placement tool as a technique to expand the narrative in a ground-breaking way through books apparently written by one of the characters in the series. This study explores the communicative dimensions applied by its developers through an exploratory-descriptive methodology that offers a qualitative analysis. We conduct a bibliographic study alongside an exclusive interview with the co-creator of the series, Carter Bays. Consequently, our study dissects the communicative process from a semantic and advertising perspective with an international reach. Finally, the results identify a paradigmatic case that takes advantage of the communicational context to build a transmedia narrative, giving rise to an intertextual and parasocial interpretation.

Tuberculosis is caused by Mycobacterium tuberculosis. If the treatment is inadequate or if host defenses are impaired, the apical lesion in primary tuberculosis expands into adjacent lung tissues and may spread via airways, lymphatic channels, or the vascular system. It may also circulate back to the lung and cause miliary pulmonary disease. Systemic miliary tuberculosis occurs when bacteria disseminate through the systemic arterial system to involve any organ. In the present study, we discuss five such cases of systemic miliary tuberculosis wherein the deceased succumbed to the illness. [ABSTRACT FROM AUTHOR]

This research examines the second season of the transmedia children's series Irabazi Arte! in relation to promoting empowerment and gender equality (Sustainable Development Goal 5). Irabazi Arte!, broadcast on Basque public television (EITB), is produced entirely in Basque and its central storyline is women's football. Using a mixed methodology, it will be analysed if and how gender equality is promoted in its transmedia universe and if it has the potential to have an impact on its young audience. A quantitatively and qualitatively positive representation of SDG 5 is found. This transmedia narrative fits the characteristics of the Generation Alpha and contributes to the progress of gender equality through educommunication, promoting equality in the Generation Alpha.

Las series de televisión se han convertido, en los últimos años, en uno de los formatos televisivos más consumidos entre la audiencia, especialmente entre los más jóvenes, llegando a calificar este momento en el que se encuentran como la edad de oro. Dentro de este estudio se plantea la necesidad de analizar tanto los personajes como los mensajes educativos que se transmiten en la serie de televisión Élite. Para llevar a cabo esta investigación, se ha optado por una metodología cualitativa a través de un análisis de contenido de las temáticas que se muestran en la serie, así como un estudio de los personajes que en ella aparecen. Entre los principales resultados obtenidos se observa cómo se tratan aspectos relacionados con el adecuado uso de las redes sociales, el ciberacoso, las relaciones homosexuales o las enfermedades como el cáncer o el VIH. Por otra parte, a través de los personajes se muestra una gran diversidad de nacionalidades, así como de orientación sexual. Como principales conclusiones, se observa como las series de televisión para adolescentes tienden a captar la atención de la audiencia juvenil a través de temáticas y personajes que resultan cercanos a ellos y con quienes se pueden identificar.

In 2013, the Walloon-Brussels Federation and RTBF created a series fund that aims to make French-speaking Belgium emerge as a land of series creation likely to appeal to an international audience. Wallonia, for a long time on the bangs of the geography of series, has become part of it and, since ‘La Trêve’ in 2016, has hosted multiple film shoots of works that could, beyond their economic and spatial effects, propose other forms of writing of the Walloon space and move the lines of representations associated with this territory often referred as 'in crisis'.

La serie Stranger Things, de los hermanos Duffer (2016-…) no recoge de manera evidente la figura del caballero andante, pero sí aparecen indicios de los rasgos característicos de la caballería, como una manifestación del camino del héroe. Además, la serie también compendia elementos propios del género como el enfrentamiento contra el terror, la búsqueda heroica y la dama sobrenatural. Los jóvenes protagonistas se erigen en una suerte de caballeros en bicicleta, ayudados por otros jóvenes y por adultos. Esta recepción del héroe y del caballero en un producto audiovisual de la cultura popular como Stranger Things da cuenta de la vigencia de estos mitos en la actualidad

Ellipsoidal and plane-elliptical surfaces are widely used as reflective, point-to-point focusing elements in many optical systems, including X-ray optics. Here the classical optical path function approach of Fermat is applied to derive a closed-form expression for these surfaces that are uniquely described by the object and image distances and the angle of incidence at a point on a mirror surface. A compact description facilitates design, modeling, fabrication, and testing to arbitrary accuracy. Congruent surfaces in two useful coordinate systems - a system centered on the ellipsoid's axes of symmetry and a mirror-centered or `vertex' system with the surface tangent to the xy plane at the mirror's center - are presented. Expressions for the local slope and radii of curvature are derived from the result, and the first several terms of the Maclauren series expansion are provided about the mirror center.

This qualitative research uses a case study to observe non-binary representation in TV fiction. The Dan character from the Spanish series HIT (RTVE, 2020–present), who is the first openly non-binary character in Spanish TV fiction, is analyzed through the lens of Queer Media Studies. The research applies a combination of content and discourse analysis. Qualitative content categories include a character’s visibility, identity, relevance, embodiment, and social interaction. Discourse analysis categories include character’s construction, lexicalization, propositional framing, and focus. Results show that Dan’s non-binary depiction revolves around three significant axes: dualism, confusion, and exceptional talent. These axes frame social attitudes toward non-binary people and are composed by a set of features identified in Dan’s case which also informs society’s mind-sets. These traits are proposed as an analytical-theoretical tool for further analyses of non-binary representation in different cultural contexts. The outcomes of this research may inform audiovisual industries, regulations and academia, and are useful to consolidate non-binary media studies. [ABSTRACT FROM AUTHOR]

Introduction: This study analyses the way in which content related to alcohol, tobacco, junk food and sports appear in the 10 most watched movies and 10 most watched series on Netflix. Methodology: To determine this, a conceptual analysis method based on a 5-minute interval coding is used. Results: The results indicate that alcohol is shown in 32.7% of the sections of the films and in 29.8% of the series. Tobacco appears in 13.2% of the intervals of the films and in 14.5% of the series. Junk food has a presence of 24.3% in movies and of 24.9% in series. Regarding sports, 7.8% of the movie sections and 8.5% of the series showed this content. Discussion: Among the conclusions, the need to transform the collective imaginary in relation to these kinds of harmful products is highlighted and, at the same time, the use of the media is promoted to encourage healthy lifestyle habits among consumers.

The existing rate of convergence of series requires a known limit of that series. Direct computation of Brun's constant as the sum of twin prime reciprocals is challenging as the convergence is agonizingly slow. Here, I introduce the relative increase of the partial sum of a series as a new rate of convergence regardless of the limit of the series. With this concept, I extract a slowly convergent part from the original sum for Brun's constant so that the remaining one converges faster. Computed data demonstrate the usefulness of the concept. As a result, I obtain an improved lower bound for Brun's constant using less computing resource and establish an approximate mapping that gives a new estimate for the constant at 1.89558413.

For the equation of a mixed parabolic-hyperbolic type with a power degeneration on the type change line, the inverse problems to determine the time-dependent factors of right-hand sides are studied. Based on the formula for solving a direct problem, the solution of inverse problems is equivalently reduced to the solvability of loaded integral equations. Using the theory of integral equations, the corresponding theorems for the existence and uniqueness of the solutions of the stated inverse problems are proved and the explicit formulas for the solution have been given.

The features of mining of a coal series are described. The stress–strain behavior of rock mass during mining of the lower strata in the series is assessed with regard to the influence of coal pillars and upper level roadways. Different variants of location of a temporary roadway on the lower stratum in a series protected by a pillar are discussed. The implemented prediction of the stress–strain behavior of rock mass is adapted to the conditions of mines in the south of Kuzbass. This prediction is used to select the geomechanically safest variant of location of the temporary roadway. [ABSTRACT FROM AUTHOR]
