Authors: Alvarado Briceño Pascuala , Bonilla Gómez Hilda , Asun Rodrigo 
Published: July 2021

Objetivo. Determinar asociación entre Calidad de Vida (CV) e Incontinencia Urinaria (IU) en mujeres de 20 a 44 años del Centro de Salud Familiar Santa Julia, Santiago de Chile. Materiales y métodos. Estudio analítico de corte transversal realizado desde septiembre a diciembre de 2018. De 661 mujeres encuestadas, 184 refirieron IU, de estas, 170 participaron en el estudio. Valor media de edad: 33,84 años. Para la IU se aplicó la Escala de Sandvik y para la CV y la CVRS, se aplicaron los instrumentos ICIQ- SF y el de Potenziani, respectivamente. Resultados. La prevalencia de IU fue 27,8 %. La severidad de la IU fue moderada en el 55,9 %, grave en un 12,3% y muy grave en un 1,8 %. Según el ICIQ-SF el impacto de la IU en la CV de moderado a muy intenso, fue de 65,9 % (18,8 % moderado, 22,9 % intenso y 24,2 % muy intenso). Según el cuestionario de Potenziani, 1 de cada 4 mujeres del estudio percibe una repercusión intensa en su CV. Se aplicó Chi Cuadrado y Coeficiente V de Cramer observando correlación positiva moderada y estadísticamente significativa de 0,419 entre severidad IU y CV. Además, correlación positiva moderada y estadísticamente significativa de 0,463 entre el impacto percibido por las mujeres y la repercusión en su CV. Conclusión. La IU afecta la CV de las mujeres desde edades tempranas y aumenta con los años. Es fundamental diagnosticar precozmente, generar políticas públicas sanitarias e implementar estrategias locales para tratar esta patología biopsicosocial.

Objective
To test whether postmortem MRI captures brain tissue characteristics that mediate the association between physical activity and cognition in older adults.

Methods
Participants (N = 318) were older adults from the Rush Memory and Aging Project who wore a device to quantify physical activity and also underwent detailed cognitive and motor testing. Following death, cerebral hemispheres underwent MRI to quantify the transverse relaxation rate R2, a metric related to tissue microstructure. For analyses, we reduced the dimensionality of the R2 maps from approximately 500,000 voxels to 30 components using spatial independent component analysis (ICA). Via path analysis, we examined whether these R2 components attenuated the association between physical activity and cognition, controlling for motor abilities and indices of common brain pathologies.

Results
Two of the 30 R2 components were associated with both total daily physical activity and global cognition assessed proximate to death. We visualized these components by highlighting the clusters of voxels whose R2 values contributed most strongly to each. One of these spatial signatures spanned periventricular white matter and hippocampus, while the other encompassed white matter of the occipital lobe. These two R2 components partially mediated the association between physical activity and cognition, accounting for 12.7% of the relationship (p = .01). This mediation remained evident after controlling for motor abilities and neurodegenerative and vascular brain pathologies.

Conclusion
The association between physically activity and cognition in older adults is partially accounted for by MRI-based signatures of brain tissue microstructure. Further studies are needed to elucidate the molecular mechanisms underlying this pathway.

Trudność zadania komunikacyjnego a bogactwo leksykalne wypowiedzi uczniów
Authors: Róg Tomasz 
Published: July 2021

Task-based language teaching has recently become a mainstream research area in second language acquisition studies. One of the underexplored areas is task design and its influence on the measures of complexity, accuracy, and fluency. While most previous research into task design focused on manipulating planning time, note-taking, or task familiarity, one of the promising lines of investigation is how task difficulty may also be conducive to L2 acquisition. Task difficulty is understood as the cognitive burden placed on a learner performing a task. In the current study learners of English as a foreign language (n=28) performed three differently designed oral communicative tasks of increasing difficulty: (1) a brainstorming task, (2) a sorting and ordering task, and (3) a problem-solving argumentative task. Task difficulty, i.e. having to employ higher-order thinking skills improved learners’ L2 lexical complexity as measured by lexical diversity, lexical density, and word-frequency counts.
Przyswajanie złożoności językowej przez uczniów z deficytami języka i mowy w nauczaniu włączającym
Authors: Karpińska-Szaj Katarzyna , Lewandowska Agata 
Published: July 2021

The article reports on an action research study which uses reformulation as its key instrument. The aim of the study was to identify the individual characteristics of acquisition of complex structures in Polish (native language) and English (foreign language) by children with speech and language deficits, learning in an inclusive environment at the upper primary level. The analysis of the gathered data focuses on Polish and English structures used by special needs students and mainstream students in their inclusive educational environment, and on the students’ ability to build/reconstruct a narrative structure – according to the unique qualities of the input text. The observed trends help to plan and organise the teaching process, which also includes the rehabilitation of speech and language in a foreign language lesson.
On the Segre invariant for rank two vector bundles on ℙ2
Authors: Roa-Leguizamón L. , Torres-López H. , Zamora A. G. 
Published: July 2021

Abstract
We extend the concept of the Segre invariant to vector bundles on a surface X. For X = ℙ2 we determine what numbers can appear as the Segre invariant of a rank 2 vector bundle with given Chern classes. The irreducibility of strata with fixed Segre invariant is proved and their dimensions are computed. Finally, we present applications to the Brill–Noether Theory for rank 2 vector bundles on ℙ2.
Rank one sheaves over quaternion algebras on Enriques surfaces
Authors: Reede Fabian 
Published: July 2021

Abstract
Let X be an Enriques surface over the field of complex numbers. We prove that there exists a nontrivial quaternion algebra 𝓐 on X. Then we study the moduli scheme of torsion free 𝓐-modules of rank one. Finally we prove that this moduli scheme is an étale double cover of a Lagrangian subscheme in the corresponding moduli scheme on the associated covering K3 surface.
The laboratory in the multidisciplinary diagnosis of differences or disorders of sex development (DSD)
Authors: Granada Maria Luisa , Audí Laura 
Published: July 2021

Abstract

Objectives
The development of female or male sex characteristics occurs during fetal life, when the genetic, gonadal, and internal and external genital sex is determined (female or male). Any discordance among sex determination and differentiation stages results in differences/disorders of sex development (DSD), which are classified based on the sex chromosomes found on the karyotype.

Content
This chapter addresses the physiological mechanisms that determine the development of female or male sex characteristics during fetal life, provides a general classification of DSD, and offers guidance for clinical, biochemical, and genetic diagnosis, which must be established by a multidisciplinary team. Biochemical studies should include general biochemistry, steroid and peptide hormone testing either at baseline or by stimulation testing. The genetic study should start with the determination of the karyotype, followed by a molecular study of the 46,XX or 46,XY karyotypes for the identification of candidate genes.

Summary
46,XX DSD include an abnormal gonadal development (dysgenesis, ovotestes, or testes), an androgen excess (the most frequent) of fetal, fetoplacental, or maternal origin and an abnormal development of the internal genitalia. Biochemical and genetic markers are specific for each group.

Outlook
Diagnosis of DSD requires the involvement of a multidisciplinary team coordinated by a clinician, including a service of biochemistry, clinical, and molecular genetic testing, radiology and imaging, and a service of pathological anatomy.
From lectures to lessons and back again:The deterritorialization of transmission inElizabeth Costello
Authors: Biti Vladimir 
Published: July 2021

AbstractJ. M. Coetzee’sElizabeth Costelloconsists of eight “lessons,” which in their turn play host to seven lectures as given either by Coetzee himself or his fictional doppelganger. When a fiction consists of lessons that embed lectures, the latter are delivered simultaneously to the present direct addressees and to absent indirect ones. Both Costello and Coetzee refuse to accept the consensual illusion of their lecture halls by preferring to address a scattered and heterogeneous readership. Their lectures break the realist illusion by drawing attention to their unreliable performers who cannot act as unbiased agents of commonality. The best way to provoke dissent is to put emphasis on the consensual reality’s discarded “real,” such as violated children, exterminated peoples, or suffering animals. By responding to its call from an ever-new point of view and establishing a migrating point of view, Costello and Coetzee untiringly distance themselves from the artifice of reality that surrounds them.
Refusing to be silenced: Claiming chaos narrative
Authors: Donnelly Colleen 
Published: July 2021

AbstractIn theWounded Storyteller, Arthur Frank proposed three types of narrative told by people attempting to reclaim their voice and the body made alien by illness – restitution, quest, and chaos. Restitution narrative has dominated media; in it, the patient simply experiences the disease and is presented passively, and the medical community is presented as having agency. In quest narrative, the experiencer becomes their own hero; their suffering brings knowledge which is then shared with the audience who bears witness and is charged with learning the lesson the experience conveys. In quest narrative, while speakers have agency that they are often robbed of in the restitution narrative, they are saddled with the imperative to inspire others. This makes the narrator a hero, but we need to ask, where does the imperative come from that demands that the narrator become a hero and an example for others? If that imperative comes from the audience and market demands, we need to recognize how they are dictating the manner in which stories are told, determining which are selected by publishers and media venues to be disseminated. The third type, the chaos narrative, is rarely encountered by audiences because the chaos narrative is usually erased. This “anti-narrative” can only be lived and cannot be told. The individual living with chronic physical or mental illness or a disability, who cannot be stoic and turn their story into a quest narrative, is rendered mute. Since restitution narrative is also unavailable to these individuals, their stories are left unspoken or unwritten. Their stories have largely been controlled by external agents. Failure to meet normate expectations has meant rejection. How prescriptive norms arose that delegitimatized the authority of chaos narrative must be understood if authentic chaos narrative is to be spoken and written.
CFD analysis and RSM optimization of obstacle layout in Tesla micromixer
Authors: Wang Xiaowen , Yang Lihong , Sun Fujia 
Published: July 2021

Abstract
As a kind of fast and efficient mixing equipment, micromixer has been applied to chemical reaction detection. Its application can not only save experimental samples but also reduce the experimental time. In micromixers, Tesla structure is widely used due to its simple structure and special flow mechanism. In this paper, CFD and response surface method are used to analyze and verify the flow field of the configuration of adding diamond obstacles in the Tesla mixer. The results show that the order of layout parameter weight from large to small is obstacle size > vertical offset > horizontal offset. And the Desirability was 0.806, the optimal diamond obstacle size is 46.35 μm and the optimal lateral offset is 18.78 μm. In addition, a constant value OF 20 μm is predicted as the optimal vertical offset of the micromixer. Compared with the Tesla-type micromixer without obstacles, the diamond-shaped barrier Tesla-type micromixer designed in this paper has higher mixing rate and lower pressure drop under the same conditions, which can be applied to chemical reactors, and can also help to improve the accuracy of chemical reaction. It can be demonstrated that the presented optimal design method of obstacles layout in Tesla mixer is a simple and effective technology to improve the liquid mixing in microfluidic devices, and it has a broad application prospect in chemical engineering.
»Über den Abgrund«

Published: July 2021

ZusammenfassungDer Artikel geht anhand einer Einzelfallstudie empirisch der Frage nach, wie Menschen aus der Grauzone zwischen Konservatismus und Rechtsextremismus sich rechte Einstellungen und Handlungsbereitschaften aneignen. Welche biographischen Dispositionen und psychischen Dynamiken, welche Gruppenprozesse und sozialen Praxen werden für diese Aneignung bedeutsam? Mittels einer tiefenhermeneutischen Analyse eines biographischnarrativen Interviews mit einem AfD-Mitglied wird verdeutlicht, dass in rechten Gruppierungen und durch rechte Propaganda ein psychosozialer Prozess angestoßen wird, der lebensgeschichtlich entwickelte Abwehrstrukturen und biographische Kompetenzen, Krisen und Konflikte zu bearbeiten, schwächt. Hierdurch erst werden im Verlauf rechter Sozialisationsprozesse psychische Dynamiken, un(v)erträgliche Erlebnisse und Affekte des Subjekts nachträglich virulent gemacht, die mittels einer völkischen Idealisierung und einer projektiven Feindbildung schiefgeheilt werden.
Spannungsfelder nationaler Zugehörigkeit am Beispiel des Haderns mit dem Titelgewinn der Fußball-Weltmeisterschaft 2014
Authors: Kühn Thomas 
Published: July 2021

ZusammenfassungUm die Dynamik des Rechtspopulismus zu verstehen, ist es wichtig sich damit auseinanderzusetzen, wie das Konzept von Nationalität und die Bedeutung von Zugehörigkeit in der Gesellschaft verhandelt werden. Der vorliegende Beitrag geht von der Annahme aus, dass der Status von nationaler Zugehörigkeit für zeitgenössische Gesellschaften uneindeutig und der Bezug einzelner Bürger*innen zu ihrer Nationalität in der Folge spannungsgeladen ist. Der vorliegende Beitrag widmet sich diesen Spannungsfeldern, indem er zunächst eine Differenzierung aus kritisch sozialpsychologischer Forschung vornimmt und dann am Beispiel eines qualitativen Forschungsprojekts die Bedeutung dieser Spannungsfelder untersucht. Dabei geht es um die Auseinandersetzung deutscher Staatsbürger*innen mit dem Titelgewinn der Fußball-Weltmeisterschaft der Männer 2014. Im Fazit wird argumentiert, dass ambivalenter nationaler Identität und damit verbundener subjektiver Mehrstimmigkeit sowohl aus wissenschaftlicher als auch aus gesellschaftspolitischer Perspektive mehr Aufmerksamkeit gebührt und damit gleichzeitig ein noch unzureichend genutztes Potenzial für einen fruchtbaren Dialog innerhalb von Gesellschaften verbunden ist.
„Vom Haben und Machen“

Published: July 2021

ZusammenfassungKinderzeichnungen als bedeutsamer Zugang zur kindlichen Perspektive auf die Welt und die eigene Position darin könnten vor allem in der kulturvergleichenden Forschung verstärkt interessieren. Versteht man Kinderzeichnungen als Bilder und damit (auch) als Träger von kulturellen Bedeutungen, in denen sich Erfahrungen und implizite Wissensbestände der Zeichnenden dokumentieren, bietet sich eine rekonstruktive Analyse an, die gleichsam ‚hinter‘ das offensichtlich Abgebildete schaut. In der vorliegenden dokumentarischen Interpretation von Kinderzeichnungen aus Ghana und Deutschland wird deutlich, wie sich die Zeichnenden zu (sozio-)kulturell spezifischen Erwartungen einerseits und zu kulturübergreifenden Entwicklungsanforderungen anderseits positionieren. Damit gelingt sowohl ein Einblick in die kindliche Perspektive auf Entwicklungs- und Sozialisationsprozesse als auch in kulturell spezifische Normierungen, welche diese Prozesse rahmen.
Evaluación financiera de la industria del cemento, cal y yeso en Colombia (2014-2019)
Authors: Rivera Godoy Jorge Alberto , Trejos Pérez Carlos Andrés , Quevedo Suárez José Luis 
Published: July 2021

La investigación reportada en el presente artículo tiene como objetivo evaluar el desempeño financiero de la industria del cemento, cal y yeso en Colombia en el lapso 2014-2019, empleando como metodología el análisis estático y de tendencias de indicadores contables y de gestión de valor que miden su crecimiento, eficiencia, eficacia, efectividad, valor económico agregado (EVA) y valor de mercado agregado (VMA).
Se encuentra que este sector aumenta sus ventas y activos, pero reduce su utilidad neta; es efectivo en el logro de utilidades, siguiendo la orientación cambiante de la eficacia en el control de erogaciones, que es amplificada por un apalancamiento financiero positivo. No obstante, destruye EVA en los últimos cuatro años, causado por el deterioro del rendimiento después de impuestos del activo neto operacional que fue superado por el costo de capital.
Estos hallazgos pueden complementarse con estudios para grupos homogéneos en edad, tamaño y naturaleza jurídica.
La politología es una fenomenología de lo político. Reflexiones alrededor de la esencia de lo político de Julien Freund
Authors: Fonseca Juan David 
Published: July 2021

En el presente artículo se explica a partir de lo expresado por Julien Freund en La esencia de lo político, la contradictoria relación que se entabla entre las utopías políticas planteadas por algunas filosofías, y la acción política sujeta a los aspectos invariables de lo político. Asimismo, se analiza el vínculo entre filosofía y política, demostrando cómo los juicios políticos pertenecen más al ámbito de la opinión que de la epistemología. Finalmente, se ofrecen algunas consideraciones expuestas por Freund, en lo que concierne a la actividad propia de la politología, entendiéndola como estudio de la esencia de lo político.
Apuestas, tensiones y posibilidades del concepto de gobernanza (sin adjetivos) en el ámbito colombiano
Authors: Rojas-Delgado Jorge 
Published: July 2021

Este artículo está orientado a reflexionar en torno al concepto de gobernanza y sus posibilidades de implementación en el ámbito colombiano, entendiendo que, aunque ha sido abordado de manera incipiente y dotado de un sinnúmero de adjetivos que consiguen desdibujar su alcance, puede llegar a profundizar la calidad de la acción pública, el agenciamiento de recursos, la coordinación de actores, así como la promoción de valores democráticos. Esta aproximación busca entonces que el potencial generativo de la gobernanza no responda a un simple arreglo teórico o refinamiento metodológico que omita el diseño institucional, los escenarios políticos, las dinámicas sociales y los contextos locales que logran muchas veces quebrar el ámbito de lo prescrito para presentarse desde lo recursivo e inédito. Es así como finalmente se apuesta por la noción de gobernanza sin adjetivos, en donde se promueva una cultura performativa que repolitice las distintas esferas de la vida social, fortalezca los espacios de participación ciudadana y reconozca la pluralidad de intereses, en un intento por dirimir las tensiones, incrementar el control ciudadano y elaborar alternativas viables con el fin de promover el bien común y la (co)responsabilidad alrededor de las necesidades más sentidas y los retos más acuciosos.
GIFTEDNESS AND TALENT

Published: July 2021

Affirmative policies arise from the need to favor some sectors of society that have suffered or continue to suffer from the effects of discrimination, injustice, racism, or exclusion; among these, in Special Education, students with gifted characteristics have become invisible to teachers, guardians, and society in general. However, the trinomial gifted black female presents threefold invisibility in our world. This study analyzes the factors that trigger the invisibility of gifted black women in Brazilian schools. We use descriptive statistics to analyze the microdata collected by surveys, evaluations, and exams carried out by the National Institute of Educational Studies and Research.
Seroprevalence of HBsAg, Anti-HBs, Anti-HCV and Anti-HIV in Behçet’s Disease
Authors: EROĞLU Esma , YAVUZ Cahit 
Published: July 2021

Introduction: Behçet's disease defined by Turkish dermatologist Hulusi Behçet is an inflammatory disease of unknown etiology and characterized by recurrent oral aphthous ulcers, genital ulcers, uveitis and skin lesions. We aimed to evaluate hepatitis B virus, hepatitis C virus and human immunodeficiency virus seroprevalence in Behçet's Disease.
Material and Method: Patients diagnosed with Behçet’s diseaseand followed up by the dermatology outpatient clinic during 12-years period between July 2008 and July 2020 were retrospectively analyzed. Demographic datas and HBsAg, anti-HBs, anti-HCV, Anti-HIV results of the patients were recorded.
Results: 359 patients with Behçet’s disease were been evaluated in this study. Of these patients, 189 (52.6%) were female, 170 (47.4%) were male and the mean age was 37.7±12.3 years. HBsAg was positive in 6 (1.6%) patients and Anti-Hbs ab in 82 (7.7%) patients. Anti HIV ab was negative in all patients. Anti-HCV antibodies were found positive in only one case (0.2%), and this was confirmed by testing for hepatitis C virus-ribonucleic acid (HCV RNA). HCV RNA was negative in this patient.
Conclusion: When compared with the general population, seropositivity rates were not detected to be high in Behçet's patients. In fact, the immunity rates were found very low. Based on such a finding, it was concluded that screening is required due to increasing immunosupressive treatments today, and individuals should be vaccinated in cases where HBV indicators are negative.In the other studies, investigating the entity, seropositivity rates have been found similar to those in the population. Considering that serological data show regional differences, we thought that, our study will contribute to the literature both national and international grades due to large patient population in our region.
