Abstract
We used data from the QUEST-La Silla Active Galactic Nucleus (AGN) variability survey to construct light curves for 208,583 sources over ∼70 deg2, with a limiting magnitude r ∼ 21. Each light curve has at least 40 epochs and a length of ≥200 days. We implemented a random forest algorithm to classify our objects as either AGN or non-AGN according to their variability features and optical colors, excluding morphology cuts. We tested three classifiers, one that only includes variability features (RF1), one that includes variability features and also r − i and i − z colors (RF2), and one that includes variability features and also g − r, r − i, and i − z colors (RF3). We obtained a sample of high-probability candidates (hp-AGN) for each classifier, with 5941 candidates for RF1, 5252 candidates for RF2, and 4482 candidates for RF3. We divided each sample according to their g − r colors, defining blue (g − r ≤ 0.6) and red subsamples (g − r > 0.6). We find that most of the candidates known from the literature belong to the blue subsample, which is not necessarily surprising given that, unlike many literature studies, we do not cut our sample to point-like objects. This means that we can select AGNs that have a significant contribution from redshifted starlight in their host galaxies. In order to test the efficiency of our technique, we performed spectroscopic follow-up, confirming the AGN nature of 44 among 54 observed sources (81.5% efficiency). From the campaign, we concluded that RF2 provides the purest sample of AGN candidates.
Le don, la dette et l’enfant. Une étude-pilote sur la réciprocité dans les familles
Authors: Fischler Claude , Levy-Basse Roseline , Smaïl Mustapha , Serog Patrick 
Published: May 2019

La thèse anthropologique d’un équilibre nécessaire entre don et contre-don s’appliquerait-elle à la relation parents-enfants ? Le déséquilibre pourrait-il entraîner des compensations symboliques et somatiques chez l’enfant ? Pour explorer et approfondir cette hypothèse issue d’observations cliniques, une enquête-pilote a porté sur un échantillon composite de parents et d’enfants suivis ou non par des professionnels de santé pour des troubles liés à l’alimentation. On observe que les parents ont massivement le sentiment de donner plus à leurs enfants qu’ils n’ont reçu eux-mêmes, qu’ils n’attendent pas de retour sinon dans un avenir indéterminé ou sous forme de travail scolaire. Les enfants, de leur côté, n’ont ni l’occasion ni le sentiment de « rendre » quoi que ce soit à leurs parents. Certains se plaignent d’un manque de reconnaissance. L’alimentation constitue un domaine particulier : le sentiment de l’investissement parental y paraît plus problématique, particulièrement chez les mères. Les données recueillies soulèvent des questions nouvelles, en relation avec l’investissement ou le surinvestissement parental et la notion de dette inter- ou transgénérationnelle.
Differences in Test Performance and Learner Satisfaction Among Nurses With Varying Autonomy Levels
Authors: Vallerand April Hazard 
Published: May 2019

ABSTRACT
A quasi-experimental study, using a posttest only design, was conducted with a convenience sample drawn from nurses in the Los Angeles area. The study sample consisted of 42 subjects, 37 females and 5 males, who volunteered to attend a continuing education course. Autonomy level was tested for all subjects prior to the course, using Ferrell's Autonomous Learner Index (ALI). Subjects were then randomly placed into one of two treatment groups: a 4-hour lecture-discussion method of instruction or a home study course with a one-month span for completion. Course content for both groups was identical. Following course completion all subjects were given a 25-question, multiple-choice posttest to test knowledge level and asked to complete a modified version of Brown and Holtzman's Study Attitudes Scale (SAS) to measure satisfaction with the educational experience. Analysis of demographic data revealed that the groups were essentially alike except in the areas of sex, present position, and nursing specialty. The t-ratio indicated no difference between the lecture-discussion and home study groups on the ALI, Content Posttest, and SAS scores. Pearson Product Moment Correlation Coefficients revealed directional support but lack of significance for Hypotheses 1, 2, and 3. Significant findings at the .05 level were obtained for Hypothesis 4, which asserted that nurse learners with a lower autonomy level, participating in the lecture-discussion method of instruction would report a higher level of satisfaction with the educational experience than those nurse learners with lower autonomy levels participating in the home study method. Methodological limitations included selection bias and sample size, lack of ability to measure entry-level knowledge, instruction bias, and errors of measurement. Study replication was recommended using a larger sample size and random sample, and refining and further testing the instruments for reliability and validity.
Tropeiros e colonos e a construção da estrada de Blumenau a curitibanos
Authors: Goularti Filho Alcides 
Published: May 2019

Este artigo tem por objetivo estudar a construção da Estrada de Blumenau a Curitibanos durante o último quartel do século XIX e início do século XX. O texto focaliza nos aspectos econômicos (fluxo mercantil), demográficos (expansão da colonização) e políticos (relação entre a Colônia e o Estado). A construção dessa estrada tinha por objetivo integrar o Vale do Itajaí, região de colonização europeia e da pequena produção mercantil, ao planalto serrano, região de grandes fazendas e tropeirismo. O texto está dividido em cinco tópicos: 1) a introdução, que destaca a construção de estradas e a definição do território catarinense; 2) a expansão da colonização e a necessidade de abrir caminhos e estradas para fixar os colonos; 3) a aproximação das duas regiões por meio do fluxo mercantil; 4) as obras de manutenção da estrada após a conclusão parcial em 1877; 5) a conclusão das obras e a ampliação dos investimentos no período republicano. Por fim, o texto também traz breves considerações finais.
Corpo, Gênero e Sexualidade no Cotidiano Escolar: Possíveis olhares
Authors: Cesar Carolina Sobreira 
Published: May 2019

A escola é marcada por conflitos e tensões sociais que influenciam o ensino e aprendizagem: inovações tecnológicas, diversidade de comportamentos, novas configurações familiares, diversidade religiosa, cultural e étnica. Nesta perspectiva, percebemos uma temática que emerge como problema em meio a tantas questões: gênero, sexualidade e o modo como a escola se posiciona diante dos discursos e práticas discriminatórias. Assim, esta pesquisa investigou o currículo praticado e sua relação com o gênero e a sexualidade no cotidiano de uma escola pública do município de Barra Mansa-RJ. A metodologia se deu por intermédio dos Estudos do Cotidiano e os instrumentos foram entrevistas semiestruturadas e o caderno de campo. Percebemos que a construção de gênero e sexualidade perpassa por questões sócio-históricas e culturais que busca normalizar comportamentos e atitudes no chão da escola.

A ASSISTÊNCIA ESTUDANTIL E A REDUÇÃO DAS DESIGUALDADES SOCIAIS NO CONTEXTO DE FRAGILIZAÇÃO DAS POLÍTICAS SOCIAIS.
Authors: Rêgo Ernny Coêlho , Benevides Marinina Gruska 
Published: May 2019

Este artigo reflete sobre a política de assistência estudantil no contexto de fragilização das políticas sociais. A análise não prescinde da compreensão da fragilização na qual se funda as políticas sociais no contexto neoliberal e os impactos da focalização nas respostas estatais. A metodologia empregou a pesquisa documental e bibliográfica. Observa-se que a assistência estudantil configura-se potencialmente estratégica para a democratização da permanência do ensino superior, contudo os contigenciamentos operados pela lógica neoliberal às políticas sociais delineiam ações que não coadunam com o compromisso de incluir socialmente pela educação.

Este artigo especifica as análises e discussões desenvolvidas sobre a temática escola: espaços e tempos de reprodução e resistências da pobreza, com foco na relação da escola com o seu território, realizadas com o objetivo de identificar como a escola se relaciona com os seus territórios empobrecidos e analisar as implicações dessa relação para a produção de resistência e da superação da pobreza. Adotou uma pesquisa qualitativa baseado no método dialético. Evidenciou que as escolas não desenvolvem uma relação efetiva com os seus territórios no sentido de reconhecê-los como espaços importantes de aprendizagem e de produção de vida.
A New Letter from Poe to Lowell on the Pioneer
Authors: Mckee Gabriel 
Published: May 2019

Abstract
Edgar Allan Poe's tale “The Tell-Tale Heart” was first published in the premiere issue of the Pioneer, an ambitious and short-lived literary journal edited by James Russell Lowell and Robert Carter. In 2013, a previously unpublished letter from Poe to Lowell, dated November 24, 1842, was auctioned at Christie's and is now in private hands. This letter contains Poe's offer of the tale to Lowell and his first mention of its title to the editor that went on to publish it. This article, based on direct examination of the letter, provides its full text, along with a contextual discussion of the Pioneer's brief existence and an exploration of the relationship between Poe and Lowell from their first correspondence in 1842 to their falling out and mutual criticism in the late 1840s. The newly discovered letter gives us a more complete picture of the publication of one of Poe's best-known tales and of the relationship between two major figures of nineteenth-century American literature.
How Poe's Devil Helped Corrupt Mark Twain's Hadleyburg
Authors: Eddings Dennis W. 
Published: May 2019

Abstract
While we have no full-length study focusing specifically on the connections between Edgar Allan Poe and Mark Twain, several books and articles provide some details of the many links between them. Such commentary almost always focuses on Poe's “serious” tales. What little notice given to the influence of Poe's comic tales on Mark Twain is sparse and almost universally negative. Yet given Mark Twain's comic genius it would seem natural not only that he would be aware of, but also appreciative of, Poe's humor. Taking it one step further, it seems to me that Mark Twain would also recognize and appreciate the satiric thrust of many of Poe's humorous tales. Furthermore, if Poe exerted the influence on Mark Twain that several critics suggest, then exploring the role of his comic tales in terms of that influence could well prove meaningful. A case for precisely this point can be made by examining the influence of Poe's comic tale “The Devil in the Belfry” on Mark Twain's “The Man That Corrupted Hadleyburg.”
In Pym's Footsteps
Authors: Tatsumi Takayuki 
Published: May 2019

Abstract
Since the 1970s I have been attracted by Poe's one and only novel, Narrative of Arthur Gordon Pym of Nantucket (1838), with its apparently disorganized but radically self-referential narrative that seemed, then, to represent allegories of speech and writing. Even in the 2010s this novel requires us to reread its textuality. For the year 2015 saw a coincidence between Ron Howard's film In the Heart of the Sea and Shinya Tsukamoto's Fires on the Plain (1952), the latter film based on the original novel written by the postwar Japanese mainstream novelist Shohei Ooka (1909–1988), a big fan of Poe's Pym. It was Ooka's Fires on the Plain that inspired that major British speculative fiction writer J. G. Ballard (1930–2009) to write one of his early major novels, The Drowned World (1962), and other stories. If my first reading of Pym in the 1980s was deconstructive, my second one in the 1990s New Historicist, my third rereading in the 2010s aims to contribute to transnational literary history. It is not necessarily the case that Poe directly produced his literary descendants, but it is highly possible that the psychic and traumatized borders of Ooka's mind-scape in wartime and Ballard's techno-scape in our hyper-capitalist age continue to elaborate anew the way we read the picturesque art of Poe's nineteenth-century landscape garden and his narrators’ crowded interior spaces for our twenty-first century.
“Nomen Fit Omen”: George Eliot's Use of Biblical Persons
Authors: Szirotny June Skye 
Published: May 2019

AbstractBecause George Eliot's aim in writing fiction was to persuade her readers to love one another, she wanted to create loveable characters. This she does by an objective and ingenious method of determining whether her characters are, for herself, likable. Endowing Biblically-named characters, such as Elisabeth and Thomas, with traits of their Biblical namesakes, she invites us to compare the two sets of characters. The first part of the article compares a number of George Eliot's characters to their namesakes. The result is that most of her fictional characters, being mirror images of the namesakes, who are all likable, are themselves likable. By likable, I do not mean that they are necessarily very virtuous; rather, they are pleasing—persons whom George Eliot, at any rate, would like as friends. (Victorian readers often thought Maggie Tullliver wicked, but many readers like her.) The last part of the article, by a brief comparison of George Eliot's hundreds of Biblically-named characters to their namesakes, proves that all of the former are, to some extent, like the latter.

Published: May 2019

A fin de contribuir al fortalecimiento de la atención multidisciplinaria y mejorar el abordaje del VIH y Sida, se realiza en el municipio de Puerto Cabezas un estudio con mujeres indígenas que asistieron al programa de VIH y Sida, en el Hospital Nuevo Amanecer durante el 2010 al primer semestre del 2014. A partir de los resultados, se logró identificar un total de 14 pacientes las cuales asisten de forma irregular al retiro de su tratamiento y revisiones mensuales. Por otro lado, se visibilizó la necesidad de incluir en el formato del expediente clínico las prácticas culturales y tradicionales de salud de los pacientes a como lo establece el MASIRAAN, a fin de favorecer una buena articulación con la medicina tradicional.Actualmente el VIH y Sida ha afectado a las diversas poblaciones existentes en la región; sin embargo, la desagregación por pueblo no es consistente ni sistemática; siendo esto una desventaja para la toma de decisiones oportunas dirigidas a las poblaciones afectadas. Se considera que ante esta situación es necesario impulsar esfuerzos para que la inclusión de estos elementos sea a lo inmediato, lo que contribuiría a brindarles a las mujeres una atención integral y de calidad.
Gender and Middle-East: An Intersectionality Perspective
Authors: Singh Rajdeep 
Published: May 2019

Intersectionality, the relations among different social variables and their interplay, is an inevitable and most employed way of analyzing the gender related issues. We also consider the intersectionality as a great window to new horizons for gender equality aspirations and research. By modifying the more traditional type of intersectional research methodology, we could build up a solid framework for future studies on gender issues particular to the Middle-East. Our goal is to offer a modern model for intersectional studies specific to middle-east, brining onboard different perspectives, usually neglected in mainstream intersectional studies on gender. This model provides a firm ground for psychological questions touching individual as well interpersonal and social dimensions. For this, we concentrate on Iran where the feminist movement is growing fast and there are reasons to believe that it has religious and social texture similar to the rest of the region. We used intersectional methodology as we consider this the most suitable for gender studies. This paper presents a novel model which offers a great unique opportunity to understand the complexity of factors involving the gender issues in a region which is growing fast but still clings to traditions. We further illustrate how the language plays a role in implementing governmental policy which brings about changes in identity and gender inequality.
Optimization of the Size of Thread Pool in Runtime Systems to Enterprise Application Integration: a Mathematical Modelling Approach
Authors: Freire Daniela L. , Frantz Rafael Zancan , Roos-Frantz Fabricia , Sawicki Sandro 
Published: May 2019

Companies seek technological alternatives that provide competitiveness for their business processes. One of them is integration platforms, software tools that build integration solutions, which allow the different applications that make up the software ecosystem to work synchronously and that new applications or functionalities be incorporated with the least impact in the existing ones. The runtime system is the component of the integration platform responsible for managing the computational resources that run the integration solution. Among these The performance of the runtime systems is directly related to the number of threads available to run the integration solution, but scaling the number of threads that provide a shorter response time is a challenge for software engineers. If this quantity is undersized, it may cause a delay in the execution; if it is overestimated, it could cause a waste of computational resources. This article presents a mathematical model, defined by differential equations, that establishes the optimum number of threads, which maximizes the expected performance gain by minimizing the execution time of the integration solution. In addition, it presents the mathematical model application, which assists the analysis of the expected gain in different architecture scenarios and quantity of threads.
Bivariate Copula-based Linear Mixed-effects Models: An Application to Longitudinal Child Growth Data
Authors: Ferreira Paulo Henrique , Fiaccone Rosemeire L , Lordelo Jairo S , Sena Samila O. L. , Duran Victor R. 
Published: May 2019

Multiple longitudinal outcomes are common in public health research and adequate methods are required when there is interest in the joint evolution of response variables over time. However, the main drawback of joint modeling procedures is the requirement to specify the joint density of all outcomes and their correlation structure, as well as numerical difficulties in statistical inference, when the dimension of these outcomes increases. To overcome such difficulty, we present two procedures to deal with multivariate longitudinal data. We first present an univariate approach, for which linear mixed-effects models are considered for each response variable separately. Then, a novel copula-based modeling is presented, in order to characterize relationships among the response variables. Both methodologies are applied to a real Brazilian data set on child growth.
2019/4 The Italian Jobs Act (Legislative Decree no. 23 of 2015) reforming the protection against unfair dismissal contrasts with the European Social Charter 1996 (IT)

2019/4 The Italian Jobs Act (Legislative Decree no. 23 of 2015) reforming the protection against unfair dismissal contrasts with the European Social Charter 1996 (IT)
On 8 November 2018 the Italian Constitutional Court prohibited the reform of the protection against unfair dismissal introduced by the so-called Jobs Act (Legislative Decree no. 23 of 4 March 2015), insofar as it imposed a requirement on the judge to quantify the compensation due for unfair dismissal based on an employee’s seniority only. According to the Court, such a requirement violated not just internal constitutional norms, but also Article 24 of the (Revised) European Social Charter of 1996. This contribution focuses particularly on the EU law questions deriving from such an important judgment.
A unuqueness theorem for Sturm-Lioville operators with eigenparameter dependent boundary conditions
Authors: Wang Yu-Ping 
Published: May 2019

In this paper, we discuss the inverse problem for Sturm- Liouville operators with boundary conditions having fractional linear function of spectral parameter on the finite interval $[0, 1].$ Using Weyl m-function techniques, we establish a uniqueness theorem. i.e., If q(x) is prescribed on $[0,\frac{1}{2}+\alpha]$ for some $\alpha\in [0,1),$ then the potential $q(x)$ on the interval $[0, 1]$ and fractional linear function $\frac{a_2\lambda+b_2}{c_2\lambda+d_2}$ of the boundary condition are uniquely determined by a subset $S\subset \sigma (L)$ and fractional linear function $\frac{a_1\lambda+b_1}{c_1\lambda+d_1}$ of the boundary condition.
Hankel determinant for certain class of analytic function defined by generalized derivative operator
Authors: Al-Abbadi Ma'moun Harayzeh , Darus Maslina 
Published: May 2019

The authors in \cite{mam1} have recently introduced a new generalised derivatives operator $ \mu_{\lambda _1 ,\lambda _2 }^{n,m},$ which generalised many well-known operators studied earlier by many different authors. By making use of the generalised derivative operator $\mu_{\lambda_1 ,\lambda _2 }^{n,m}$, the authors derive the class of function denoted by $ \mathcal{H}_{\lambda _1 ,\lambda _2 }^{n,m}$, which contain normalised analytic univalent functions $f$ defined on the open unit disc $U=\left\{{z\,\in\mathbb{C}:\,\left| z \right|\,<\,1} \right\}$ and satisfy \begin{equation*}{\mathop{\rm Re}\nolimits} \left( {\mu _{\lambda _1 ,\lambda _2 }^{n,m} f(z)} \right)^\prime > 0,\,\,\,\,\,\,\,\,\,(z \in U).\end{equation*}This paper focuses on attaining sharp upper bound for the functional $\left| {a_2 a_4 - a_3^2 } \right|$ for functions $f(z)=z+ \sum\limits_{k = 2}^\infty {a_k \,z^k }$ belonging to the class $\mathcal{H}_{\lambda _1 ,\lambda _2 }^{n,m}$.
Dermoscopy of Dermatofibrosarcoma Protuberans: What Do We Know?
Authors: Escobar Gabriela F. ,  Ribeiro Caroline  K. , Leite Leandro L. , Barone Carolina R. , Cartell André 
Published: May 2019

Background: Dermatofibrosarcoma protuberans (DFSP) is an uncommon mesenchymal tumor of intermediate malignancy. Its rarity and slow progression often imply a delayed diagnosis. There are few previous reports of dermoscopic features of DFSP and most are single case descriptions.
Objectives: To report 2 cases of DFSP and their dermoscopic features, as well as conduct a review of all previous cases published addressing the use of dermoscopy in this tumor.
Methods: We conducted a literature search for all dermoscopic cases of DFSP. In addition, we presented 2 additional cases and compared them to the earlier findings.
Results: We summarized the main dermoscopic findings of DFSP based on analysis from 32 patients. The most common features of this tumor are the presence of vessels (81%), followed by a pigmented network (78%) and a pinkish background (66%).
Conclusions: DFSP can mimic benign lesions and the diagnosis may be challenging. Dermoscopy is an important tool that may enhance clinical suspicion toward the diagnosis of DFSP.
