The Dreadful Dance of the Goddess: Creativity and Mimesis in a Possession Cult of Assam
Authors: Majo Garigliano Irene
Published: February 2019

Every year in August devotees flock to the Kāmākhyā temple (Guwahati, Assam), to attend and observe the Deodhāni-nāc, (the dance [nāc] of the sound [dhāni] of god [deo]). The main feature of this three-day festival is the dance of the deodhās. The deodhās, Assamese males, become possessed by the goddess Kāmākhyā (and the other deities connected to her) and dance to the beat of drums. The dance of deodhās reproduces to some extent the character and iconography of the possessing deities, but is not limited to that. Through the use of his body, each deodhā actively interprets this shared image of the deity, dancing in a singular way. The paper focuses on the creative, yet unconscious process through which each deodhā shapes his peculiar dancing style.
„Niewiasty kresowe”

Women of the Kresy. The Female in the Works of Józef Antoni Rolle – from History to Literature and MythThe article offers an analysis of depictions of women in Józef Apolinary Rolle’s literary output. The source material are Rolle’s numerous short stories published in a number of collections and series in 1872-1894, including a collection entitled Women of the Kresy. In his works Rolle created the myth of woman of the eastern territories of interwar Poland (Kresy Wschodnie), a courageous amazon, a female warrior, by sketching portraits of historical gures of the 16th and 17th centuries. In the short story entitled Women in Kamianets under Turkish Siege (1672) the author expressed this myth in a collective portrait of women of different nationalities and faiths who defended the fortress of Kamianets Podil’skij against the Turks. In other works Rolle depicted women engaged in politics and struggling to strengthen their family’s position. The latter attitude became dominant in the 18th century, when women were no longer directly engaged in warfare. The women described by Rolle enjoy considerable individual freedom, which provides thems with more opportunities (including the freedom to choose a husband and the freedom to divorce) compared to their compatriots in the Polish west. Women who lived in partitioned Poland in the 19th century were depicted by Rolle as ones who were responsible for the family, and for the transmission of family traditions, which fits in with the myth of the Polish Mother. More broadly, the image of women of the Kresy fits in with the myth of the region itself. This tradition was continued and developed in the early 20th century by the author’s son, the historian and publicist, Michał Rolle, among others.
ON THE DEVELOPMENT OF A NOVEL TECHNIQUE FOR HYDRIDING USING ZIRCONIUM HYDRIDE POWDER
Authors: Hanlon Sean , Read Scott , McCaugherty Kevin
Published: February 2019

Zirconium alloys are of particular interest for applications within the nuclear industry given their low thermal neutron capture cross-section to strength ratios, adequate corrosion resistance, and high temperature stability. However, zirconium alloys are susceptible to hydrogen embrittlement, which limits the service lives of zirconium alloy components in reactor systems. Hydrogen charging, or hydriding, is a technique used to artificially age ex-service or as-received material to predetermined hydrogen concentrations for material testing on representative specimens. This study presents a thermo-mechanical approach to precision hydriding. Discussion on the development and commissioning of a suitable apparatus, called the Thermomechanical Hydrogen Ingression System (THIS), is provided. Hydriding results from commissioning as well as several repeatability tests are reported, which demonstrate the viability of the technique and equipment.
Skin cancer
Authors: Peate Ian
Published: February 2019

Skin cancer is a common type of cancer. The healthcare assistant and assistant practitioner (HCA and AP) are in an ideal position to recognise abnormal skin conditions and to report these. In order to do this, there is a need to have an understanding of the anatomy and physiology of the skin. This article provides an overview of the anatomy and physiology of the skin; for completeness, this article also includes the appendages (the glands, hair and nails).

This article provides the incidence of skin cancer, the various risk factors, along with information concerning health promotion. The signs and symptoms are outlined and the methods of diagnosis are discussed. The various treatment options are described.

A glossary of terms has been included, along with five multiple-choice questions provided to promote learning and application in practice.

How do supervisor support and social care matter in long-term care? Correlates of turnover contemplation among long-term care facility workers
Authors: Virdo Guytano , Daly Tamara
Published: February 2019

This study examined long-term care workers’ contemplation to leave their current employment situation. Direct care workers from three Canadian provinces were surveyed. Intention to leave was measured with a survey question asking participants whether they had seriously considered quitting their job recently. The results of the binary logistic regression indicated that both immediate supervisor support and social care tasks performed were statistically significant predictors of intention to leave. Higher levels of supervisor support and more social care tasks performed regularly were associated with lower intention to quit among direct care workers.
Ambivalence, families and care
Authors: Pillemer Karl , Suitor J. Jill , Baltar Andrés Losada
Published: February 2019

Although research shows that most parents and adult children report generally positive and supportive ties, there is also evidence that negative interactions and emotions are common in intergenerational relationships. To investigate this complexity, researchers have moved beyond simple models to orientations and approaches that recognise contradictory emotions and attitudes regarding family relationships in later life. These efforts have given rise to what has come to be termed the ‘intergenerational ambivalence’ perspective. In this article, we explore the applicability of this perspective to the issue of family caring. We begin by reviewing recent developments in the intergenerational ambivalence perspective. We then discuss a paradox: although caring appears to be a situation particularly prone to conflicting emotions, little research has focused specifically on ambivalence among carers. We present results from our work that shed light on the measurement of carer ambivalence, as well as substantive findings regarding sources of ambivalence for carers.
Challenges in the coordination of volunteer activities in long-term care services
Authors: Tingvold Laila , Skinner Marianne Sundlisæter
Published: February 2019

The need for more personnel in the care sector has made politicians call upon contributions from the voluntary sector. Policy documents, however, offer little insight into how coordination between staff and volunteers is supposed to work in practice. An interview study with managers in long-term care and activity leaders from voluntary organisations was conducted. The results show that the coordination of volunteer and staff efforts was challenging. We found a lack of understanding between staff and volunteers about the rationale and extent of voluntary work. More focus is needed on practical measures to implement voluntary work in long-term care.

Authors: Rodrigues Ana Luísa
Published: February 2019

A revolução digital contemporânea, a par da economia global, trouxe novos horizontes e desafios à educação, nomeadamente a necessidade de construir e desenvolver novas competências e uma cultura digital em contexto educativo. A integração das tecnologias digitais no processo de formação de professores apresenta diversas dificuldades e constrangimentos e, por sua vez, desafios, sobre os quais é importante refletir. Utilizando uma metodologia de estudo de casos múltiplos, foram analisados dois processos de formação de professores, um caso num curso de formação inicial e outro num projeto de formação continuada de professores. Os resultados salientaram a importância da relação entre a integração educativa das tecnologias digitais e a necessidade de utilização de metodologias e técnicas pedagógicas ativas. As principais dificuldades identificadas incluíram a falta de tempo, a visão restrita do potencial pedagógico das tecnologias e a resistência à mudança, a falta de equipamentos tecnológicos e de suporte técnico, colocando-se o desafio fundamental na necessidade de uma formação de professores eficaz na integração pedagógica das tecnologias digitais.
IMAGENS BENJAMINIANAS PARA PENSAR RELAÇÕES ENTRE INFÂNCIA, EDUCAÇÃO DE CRIANÇAS PEQUENAS E NATUREZA
Authors: Vieira Daniele Marques
Published: February 2019

Este texto apresenta um ensaio cujo objetivo é pensar relações entre infância, educação de crianças pequenas e natureza pelo diálogo narrativo. Parte da perspectiva benjaminiana sobre cultura infantil para pensar a ação da criança no contexto educativo e, para isto, vale-se da experiência educativa e sua reflexão, a fim de compreendê-la. Inspira-se em estudos acerca de indagações narrativas (CONTRERAS, 2017) como possibilidade de pensar relações educativas com o uso de fotografias (VIEIRA, 2016) e propõe uma metodologia de investigação com memórias narrativas e narrativas visuais (COUTINHO, 2010) à produção de dados a serem analisados. Denota-se pela possibilidade reflexiva da narratividade da memória e da fotografia, que se voltar a fragmentos do vivido oferece como possibilidade, para além da interpretação, pensar o lugar dos sujeitos nas relações que decorrem de suas interações com o meio e consigo próprio.

Memória e identidade: uma jornada semiótica do self em True Detective
Authors: Ferro Jeferson , Andacht Fernando Torres
Published: February 2019

Este artigo propõe uma leitura semiótica da relação entre memória e identidade através da análise de uma cena da segunda temporada da série True Detective (HBO, 2015). Buscamos entender como o processo de rememoração – neste caso, desencadeado pela presença de uma mancha no teto do quarto do protagonista – revela a jornada do self, dentro do contexto da produção audivisual contemporânea, no qual as narrativas da identidade ganharam destaque. Para isso, nos apoiamos na exegese do signo icônico peirceano feita por Ransdell (1997), e no trabalho de Andacht e Michel (2005) a respeito do self semiótico. A partir de um exemplo ficcional, procuramos demonstrar que a identidade enquanto um processo autointerpretativo está baseada na semiose, e que o exercício da narração da própria vida, o qual só pode ser feito a partir de lembranças, produz a geração presente dos seus signos.

Analiza czynników wpływających na zdolność zapamiętywania treści kursów MOOC (masowych otwartych kursów online): badanie sondażowe
Authors: Honea Kate S. , El Said Ghada R.
Published: February 2019

Masowe otwarte kursy online (Massive Open Online Courses – MOOC) zawierają w sobie potencjał, który zdolny jest stworzyć nowe możliwości w recepcji i edukacji odbiorców globalnych. A jednak, jak sugerują dostępne dane, jedynie niewielka część biorących udział w kursach MOOC uczestniczy w nich do końca i pomyślnie je kończy. Dodatkowo czynniki projektowania i implementacji kursów, które wpływają na proces zapamiętywania studenta, pozostają nadal nie do końca zrozumiałe. Artykuł przedstawia wyniki badania sondażowego przeprowadzonego wśród 379 uczestników kursów, studentów uniwersytetu kairskiego, biorących dobrowolnie udział w dowolnie wybranych kursach MOOC, którzy potraktowali je jako dodatkowy element kształtujący ich rozwój naukowy. 122 uczestników kursów (32,2%) ukończyło wybrany kurs. Pośród tej grupy nie zaobserwowano żadnych istotnych różnic w poziomie wykonania mających związek z płcią uczestników, aktualnym poziomem zaawansowania studiów (studenci przed licencjatem i studenci podyplomowi) czy też zastosowaniem konkretnej platformy MOOC. Badanie sondażowe dotyczące odbioru kursów wykonane po ich ukończeniu dowodzi, że treść kursu MOOC była znaczącym czynnikiem prognostycznym dotyczącym zdolności zapamiętania danego kursu, przy tej zależności ulegającej pośredniczącej reakcji wpływu treści kursu na spodziewaną efektywność kursu. Za kolejny istotny czynnik prognostyczny w zapamiętywaniu treści kursu uznano interakcję uczestnika z instruktorem danego kursu. Ogólnie rzecz biorąc, oba wspomniane konstrukty teoretyczne dpowiedzialne były za 79% wariancji dotyczących zdolności zapamiętywania kursów MOOC.

Oprawa kaliskich druków z 1620 roku udekorowana radełkiem jagiellońskim z popiersiem kanclerza wielkiego koronnego Jana Zamoyskiego
Authors: Muraszko Michał
Published: February 2019

W komunikacie zaprezentowano oprawę dwóch kaliskich druków z 1620 roku, którą udekorowanoza pomocą radełka jagiellońskiego z wizerunkiem kanclerza wielkiego koronnego Jana Zamoyskiego. Wolumin ten był darem Stanisława Zakrzewskiego (zm. 1631) dla Andrzeja Baranowskiego (zm. 1631), kanonika gnieźnieńskiego i krakowskiego, kantora poznańskiego, prepozyta łowickiego. Za unikatowością wymienionego narzędzia przemawia obecność wizerunku polskiego możnowładcy, niezwiązanego bezpośrednio z rodziną panującą. Niewykluczone, że przedstawiony egzemplarz został sporządzony w niezidentyfikowanej introligatorni warszawskiej. Powstał on z pewnością w przedziale od 1620 do 1631 roku, a zatem pomiędzy datą wydania druków a datą śmierci Zakrzewskiego i Baranowskiego.
Działalność wydawnicza i publikacje Towarzystwa im. Michajła Kaczkowskiego w latach 1875–1885 – ujęcie ogólne
Authors: Sedliar Oleksandr
Published: February 2019

W niniejszym tekście charakteryzuję skrótowo działalność wydawniczą oraz publikacje (książki niewielkich rozmiarów i objętości, publikowane z comiesięczną częstotliwością) ukraińskiego Towarzystwa im. Michajła Kaczkowskiego w okresie pierwszych 10 lat jego funkcjonowania. Było to stowarzyszenie rusofilskie, działało w Galicji Wschodniej i realizowało zadania oświatowe na rzecz miejscowych Ukraińców (Rusinów), zarówno ze środowisk miejskich, jak i wiejskich. Główną formę wykonawczą stanowiło wydawanie i rozpowszechnianie broszur o nastawieniu popularyzatorskim. Autorami byli przeważnie amatorzy, ale tematyka była rozległa. Wkraczała w różne obszary wiedzy – w ujęciu popularnym i z zachętą do czytania.W początkach lat 80. XIX wieku zaostrzyła się na tych obszarach walka polityczna. Władze regionalne zaczęły silniej przeciwdziałać przedsięwzięciom rusofilskim, co miało wpływ również na stosowne wyprofilowanie edytorskiej działalności Towarzystwa. Znaczenie miał także wzrost środowiskowej aktywności społecznej oraz istotne powiększenie się publiczności czytającej. Nie bez wpływu pozostawała też oferta konkurencyjna ze strony innych organizacji oświatowych – ukraińskich oraz polskich.

Na Powszechnej Wystawie Krajowej w Poznaniu (16 maja – 30 września 1929), będącej podsumowaniem dorobku dziesięciu lat istnienia niepodległej Polski w dziedzinie gospodarczej, społecznej i kulturalnej, nie zabrakło zagadnień związanych z szeroko pojętym tematem książki. Była ona obecna i widoczna w wielu pawilonach wystawowych (np. instytucji kulturalno-oświatowych, wychowania fizycznego, pracy kobiet, oświaty rolniczej i kultury wsi, w dziale bibliotek w Pałacu Rządowym), ale w dwóch miejscach eksponowano ją w sposób szczególny. W dziale Piękna Książka mieszczącym się w Pałacu Sztuki położono nacisk na zewnętrzną szatę książki i pokazano prace artystów grafików, wydawców, drukarzy i introligatorów. W pawilonie Prasa i Książka, zaprojektowanym przez Rogera Sławskiego, obok stoisk redakcji różnych tytułów prasowych umieszczono stoiska 20 wydawców książek z całej Polski (takich jak Gebethner i Wolff, M. Arct, Zakład Narodowy im. Ossolińskich, „Książnica-Atlas”, Drukarnia i Księgarnia Św. Wojciecha). Poznań przez kilka dni był ponadto stolicą polskiej książki – do miasta zjechali również miłośnicy książki i ludzie zawodowo z nią związani. W dniach 29 maja – 2 czerwca 1929 roku odbyły się II Zjazd Bibliotekarzy Polskich i IV Zjazd Bibliofilów Polskich, połączone z jubileuszem stulecia istnienia Biblioteki Raczyńskich i stulecia pierwszego wydawnictwa Biblioteki Kórnickiej.

Model wychowania w rodzinie ziemiańskiej w pierwszej połowie XIX wieku na przykładzie domu Stanisława Kostki Zamoyskiego i jego córki Celiny Działyńskiej
Authors: Wróbel-Lipowa Krystyna
Published: February 2019

Upbringing of children in aristocratic families in the first half of the 19th century, based on Stanislaw Kostka Zamoyski and his daughter Celina DziałyńskiUpbringing and education was a matter of great importance among the Polish landed gentry. The education of male descendants was particularly essential, because they were expected to hold important office, increase the family’s wealth and possessions and become a source of pride to the family in the future. According to Stanislaw Kostka Zamoyski XII, Majoratsherr in Zamość, the family home set the best example of upbringing to the younger family members. Therefore, children needed to have positive role models in their parents, who would provide them with advice, care and look after them. Small children were introduced to harsh conditions of everyday life. In order to positively shape children’s personalities, to help them to become open, gentle, reasonable, and kind people, teachers were not allowed to set them a bad example. The XII Majoratsherr’s children in Zamość were raised by parents who called for strict obedience and respect. Stanisław Kostka Zamoyski’s daughter Celina Działyńska raised her offspring in the same manner. She taught them respect for ordinary people – service and help for the needy. The above mentioned methods produced a positive effect in the future. Children raised in this way became aware of their responsibilities to the family and homeland.

Background

The Quality of Life in Short Stature Youth (QoLISSY) questionnaire is a condition-specific instrument for measuring the health-related quality of life (HRQoL) in short statured children/adolescents from patients’ and parents’ perspectives. The aim of this study was to investigate the psychometric properties of the Greek version of the QoLISSY questionnaire.

Methods

The original European QoLISSY scales were translated into Greek following the guidelines for linguistic validation and applied to 184 dyads of children 8–18 years old and their parents, as well as to 14 parents of children 4–7 years old in Greece. The field testing responses to the Greek version of QoLISSY were analyzed.

Results

The qualitative analysis of the Greek data provided results consistent with the European sample. The subsequent field test showed acceptable internal consistency (Cronbach α between 0.67–0.93) and high test-retest reliability (intraclass correlation coefficients [ICC] ≥0.70). Correlations with the generic KIDSCREEN questionnaire indicated good convergent validity. Confirmatory factor analysis (CFA) also yielded acceptable results. Higher HRQoL for taller children suggests that QoLISSY was able to detect significant height-related differences.

Conclusions

The Greek version of the QoLISSY questionnaire is psychometrically sound and its use is recommended in further clinical research to ascertain the impact of short stature (SS) and treatments in Greek children/adolescents and families.
Dynamical Mechanical Properties of Polypropylene Composites Filled with Olive Pit Particles
Authors: Gümüş Beril Eker , Yağci Özlem , Erdoğan Duygu Ceylan , Taşdemir Münir
Published: February 2019

Wood Polymer Composites (WPCs) have attracted attention in recent years because of growing ecological, social, and economic awareness. This study focuses on polymer composites filled with olive pit particles. In the present study, the test specimens were prepared with different ratios of mixtures that contain polypropylene (PP), olive pit particles in four different concentrations (5.0, 10.0, 15.0, and 20.0 wt%), and maleic anhydride as modifier. The mechanical, thermal, and viscoelastic properties of the WPC were obtained using Dynamic Mechanic Analyzer test equipment and a thermogravimetric differential thermal analyzer. Fourier transform infrared spectroscopy was carried out in order to determine the chemical bonds of these materials. The specimens were also characterized by scanning electron microscopy. The results of the study demonstrated that olive pit particles could be used as reinforcement for PP because of their good thermal and mechanical effects.
Interrelationship of Thermal Effects on Calcium Sulfate Dihydrate Casts Containing Borax and Kaolin: Differential Thermal Analysis (DTA), Thermogravimetric Analysis (TGA), and Contact Dilatometry
Authors: Engbrecht Dick C. , Hirschfeld Deidre A.
Published: February 2019

The core composition of gypsum wallboard is calcium sulfate dihydrate (CaSO4·2H2O) with varying impurities, additives, or both. This study compares two commercially calcined sources of hemihydrate (CaSO4·½H2O) from a natural source and a synthetic by-product of flue gas desulfurization and neutralization to reagent grade hemihydrate. Two common ingredients, borax and kaolin, are mixed into a slurry with distilled water. The analysis supports the hypothesis that minor components in the cast have an effect on the high temperature performance of gypsum casts. The analysis is enhanced when the differential thermal analysis, thermogravimetric analysis, and dilatometry data are combined to study the changes in density versus heat flow. Specifically, the thermal performance is affected by (1) the impurities found in hemihydrate sources; (2) during the fluidization phase, the reaction of borax with free Ca++ ions to form new borate salts that melt at lower temperatures; and (3) the intercalation of these and other ions with kaolin, providing thermal stability by reducing the formation of thermally active salts.

Although muscle development has been widely studied in Drosophila melanogaster there are still many gaps in our knowledge, and it is not known to which extent this knowledge can be transferred to other insects. To help in closing these gaps we participated in a large-scale RNAi screen that used the red flour beetle, Tribolium castaneum, as a screening platform. The effects of systemic RNAi were screened upon double-stranded RNA injections into appropriate muscle-EGFP tester strains. Injections into pupae were followed by the analysis of the late embryonic/early larval muscle patterns, and injections into larvae by the analysis of the adult thoracic muscle patterns. Herein we describe the results of the first-pass screens with pupal and larval injections, which covered ∼8,500 and ∼5,000 genes, respectively, of a total of ∼16,500 genes of the Tribolium genome. Apart from many genes known from Drosophila as regulators of muscle development, a collection of genes previously unconnected to muscle development yielded phenotypes in larval body wall and leg muscles as well as in indirect flight muscles. We then present the main candidates from the pupal injection screen that remained after being processed through a series of verification and selection steps. Further, we discuss why distinct though overlapping sets of genes are revealed by the Drosophila and Tribolium screening approaches.

Además, pudo verificarse que la distancia, diferencias idiomáticas y la mediterraneidad de Paraguay pueden repercutir en el comercio bilateral.
De dragón revolucionario, a tímido, y ahora rejuvenecido Las etapas de la política exterior china
Authors: Vélez Serrano Mayra
Published: February 2019

Desde la toma de poder de Xi Jinping, se ha estado debatiendo sobre el futuro de la política exterior china. Sin embargo, estos debates carecen de contexto histórico o ideológico. Dado el carácter hipercentralizado del sistema político chino, la política exterior se debe analizar usando como fundamento las Ideología Guías y los Principios Guías creados por distintos líderes del país. Esto permite entender tanto los factores ideológicos de su política exterior, así como las estrategias y acciones que China ha tomado a nivel internacional. Mediante el análisis de documentos primarios, discursos, libros blancos y documentos secundarios, esta investigación propone que la política exterior china (desde 1949) ha tenido tres etapas distintivas. La primera etapa, que se extiende durante el período en que Mao Zedong estuvo en el poder, se caracteriza por la creación de Principios Guías enfocados en el activismo revolucionario e internacional. La segunda etapa, que comienza con Deng Xiaoping y concluye con Hu Jintao (1978-2012), se define como una etapa tímida, renuente de llamar la atención o tomar liderazgo internacionalmente. Mientras que la última etapa, ha comenzado con Xi Jinping (2013) y se diferencia por una mayor asertividad, confianza y disponibilidad de tomar liderazgo ante el sistema internacional. Este artículo es un breve compendio de los factores históricos e ideológicos que ponen en contexto la evolución de la política exterior de China y la relación de Xi Jinping con la política de su antecesores.
Retos y aprendizajes de integrar psicología positiva y ejercicio físico en los Estudios Generales: relatos desde la praxis académica
Authors: Barrantes Brais Kristy , Gutiérrez Miranda Marcela , León Fernández Maribel , Sancho Ugalde María de los Ángeles
Published: February 2019

El presente artículo se desarrolla como un relato de experiencia que resulta de un proceso académico impartido en la Universidad Nacional, específicamente en el Centro de Estudios Generales. El proceso tuvo como objetivo promover el bienestar psicológico de estudiantes universitarios mediante intervenciones en psicología positiva (IPP) y ejercicio físico y, a su vez, desarrollar capacidades en el personal académico del Centro de Estudios Generales para gestionar intervenciones de psicología positiva. La metodología empleada en este proyecto académico consistió en una serie de intervenciones mediante los siguientes tres cursos: 1) ambiente y salud, 2) la imagen de la persona adulta mayor en los diferentes textos y 3) taller de expresión literaria: cuento y poesía. Las experiencias particulares del desarrollo de las intervenciones en cada curso se reseñan en todo este relato. Asimismo, de lo anterior se obtuvieron los retos y aprendizajes para cada curso; además, se brindó capacitación sobre las bases teóricas y el procedimiento de implementación de las tres IPP reseñadas. Al finalizar el proceso de capacitación, de manera conjunta se determinaron las formas pertinentes de incluir los principios e intervenciones de psicología positiva y educación positiva en la estrategia metodológica del programa de curso. Dicha experiencia generó posibilidades para que las diferentes disciplinas trabajaran de manera estrecha en un plan común para la praxis académica en la docencia e investigación; como pedagogía multidisciplinaria se enrumba hacia la interdisciplinariedad.

Authors: Barquero Alfaro Julio , Chacón Chespedes Melissa
Published: February 2019

En el siguiente artículo se presenta un recurso de mediación pedagógica mediante la técnica del teatro foro en la Universidad Nacional. La técnica se utiliza como una herramienta colectiva de debate y reflexión grupal en torno a determinadas problemáticas sociales y cuyo objetivo es la representación de una obra de teatro corta, en la que se exponen situaciones opresivas y se logran reconocer los principales discursos y roles sociales presentes la vida cotidiana. La técnica se aplica con estudiantes de la universidad como continuación de dos cursos pasados cuyo nombre era Teatro del Oprimido: una perspectiva práctica del humanismo (2016-2018) y en el marco del proyecto Una ventana al teatro: aportes artísticos en la mediación pedagógica (2015-2017). Por lo tanto, esta técnica se realiza como medio para fomentar reflexión crítica y la intervención activa del público en busca de soluciones al problema expuesto en cada representación.

How prepared are students for the various transitions in their medical studies? An Australian university pilot study
Authors: Moro Christian , Spooner Anne , McLean Michelle
Published: February 2019

This article was migrated. The article was marked as recommended. Becoming a doctor involves a series of transitions that require medical students to be equipped with the appropriate knowledge, skills, confidence and professional approach at each step. This pilot cross-sectional study canvassed five cohorts immediately after completing Years 1-5 in a five-year undergraduate medical program (Gold Coast, Australia) regarding their preparedness for the next year. The survey, an amalgamation of two validated inventories, was tailored for each year group to include the expected competencies in five areas. Despite a low response, those who did participate provided valuable information regarding their competence and confidence in terms of their interpersonal and intrapersonal skills, their clinical skills, their ability to apply their theoretical knowledge and investigations. Time management and balancing work and their studies were some areas in which support might be needed. Generally, all student felt comfortable with the communication and physical examination skills but up to half of some of the more senior students were not confident towards dealing with a violent patient and about 20% did not feel at ease communicating and assessing a patient with a mental health issue. Students identified two other areas that requiring curriculum interventions: Working with patients who might be using non-allopathic medications and calculating drug doses. As both impact on patient outcomes, a follow-up study is required. Different recruitment strategies need to be investigated.
Assembléia de peixes associados a ambientes consolidados no litoral do Paraná, Brasil: uma análise qualitativa com notas sobre sua bioecologia
Authors: Hackradt Carlos Werner , Félix-Hackradt Fabiana Cézar
Published: February 2019

Recentemente, estudos com peixes recifais vêm recebendo cada vez mais atenção dos pesquisadores. Na costa brasileira cinco províncias zoogeográficas foram determinadas, sendo o Paraná incluído na província sul-sudeste. Utilizando-se do censo visual sub-aquático para acessar a fauna de peixes recifais, avaliou-se os ambientes naturais e artificiais. Observou-se que a heterogeneidade de ambientes na região configura diferenças na estrutura da ictiofauna influenciada pela matriz arenosa que envolve os ambientes artificiais e pelo efeito atrator destas estruturas evidenciado pela maior presença de espécies pelágicas, efeito diluído no entorno dos ambientes insulares avaliados. A aparente pobreza de espécies, quando comparado com outros locais pertencentes à mesma província, pode ser efeito de um filtro biológico local ou apenas um reflexo da inexistência de estudos na região.
T Cells Play a Causal Role in Diastolic Dysfunction during Uremic Cardiomyopathy
Authors: Winterberg Pamela D. , Robertson Jennifer M. , Kelleman Michael S. , George Roshan P. , Ford Mandy L.
Published: February 2019

Significance Statement

Uremic cardiomyopathy, which features left ventricular hypertrophy, diastolic dysfunction, and impaired myocardial strain, predicts mortality in patients with CKD. In this study, the authors present findings supporting emerging evidence that T cells play a causal role in diastolic dysfunction during CKD. In a mouse model of CKD, they demonstrate that T cells infiltrate the heart and lead to diastolic dysfunction and impaired ventricular strain, whereas depletion of T cells improves diastolic function and myocardial strain. They also show that in children with CKD, increasing frequency of T cells bearing markers of sustained activation (PD-1 and CD57) is associated with echocardiographic indications of worsening diastolic function. Future research may inform novel therapies that target T cell function to mitigate early subclinical myocardial dysfunction during CKD.

Background

Uremic cardiomyopathy, characterized by left ventricular hypertrophy, diastolic dysfunction, and impaired myocardial strain, contributes to increased cardiovascular mortality in patients with CKD. Emerging evidence suggests a pathogenic role for T cells during chronic heart failure.

Methods

To determine whether T cells contribute to uremic cardiomyopathy pathogenesis, we modeled this condition by inducing CKD via 5/6th nephrectomy in mice. We used flow cytometry to assess expression of markers of T cell memory or activation by lymphocytes from CKD mice and controls, as well as lymphocyte capacity for cytokine production. Flow cytometry was also used to quantify immune cells isolated from heart tissue. To test effects of T cell depletion on cardiac function, we gave CKD mice anti-CD3 antibody injections to deplete T cells and compared heart function (assessed by echocardiography) with that of controls. Finally, we correlated T cell phenotypes with structural and functional measures on clinically acquired echocardiograms in children with CKD.

Results

Mice with CKD accumulated T cells bearing markers of memory differentiation (CD44hi) and activation (PD-1, KLRG1, OX40), as reported previously in human CKD. In addition, mice with CKD showed T cells infiltrating the heart. T cell depletion significantly improved both diastolic function and myocardial strain in CKD mice without altering hypertension or degree of renal dysfunction. In children with CKD, increasing frequency of T cells bearing activation markers PD-1 and/or CD57 was associated with worsening diastolic function on echocardiogram.

Conclusions

CKD results in an accumulation of proinflammatory T cells that appears to contribute to myocardial dysfunction.

Significance Statement

Dysregulated iron metabolism plays an important pathogenic role in AKI in animal models, but limited data are available on circulating iron parameters in human AKI. To assess the association of plasma catalytic iron, total iron, transferrin, TSAT, ferritin, free hemoglobin, and hepcidin with 60-day mortality, the authors examined observations in a cohort study of 807 critically ill patients with AKI (all requiring RRT) who were enrolled the ARF Trial Network study. They found that higher concentrations of catalytic iron and lower concentrations of hepcidin are each monotonically and independently associated with increased mortality. These findings identify plasma catalytic iron and hepcidin as potentially useful prognostic markers or therapeutic targets in patients with AKI requiring RRT.

Background

Iron is a key mediator of AKI in animal models, but data on circulating iron parameters in human AKI are limited.

Methods

We examined results from the ARF Trial Network study to assess the association of plasma catalytic iron, total iron, transferrin, ferritin, free hemoglobin, and hepcidin with 60-day mortality. Participants included critically ill patients with AKI requiring RRT who were enrolled in the study.

Results

Of the 807 study participants, 409 (51%) died by day 60. In both unadjusted and multivariable adjusted models, higher plasma concentrations of catalytic iron were associated with a significantly greater risk of death, as were lower concentrations of hepcidin. After adjusting for other factors, patients with catalytic iron levels in the highest quintile versus the lowest quintile had a 4.06-fold increased risk of death, and patients with hepcidin levels in the lowest quintile versus the highest quintile of hepcidin had a 3.87-fold increased risk of death. These findings were consistent across multiple subgroups. Other iron markers were also associated with death, but the magnitude of the association was greatest for catalytic iron and hepcidin. Higher plasma concentrations of catalytic iron and lower concentrations of hepcidin are each independently associated with mortality in critically ill patients with AKI requiring RRT.

Conclusions

These findings suggest that plasma concentrations of catalytic iron and hepcidin may be useful prognostic markers in patients with AKI. Studies are needed to determine whether strategies to reduce catalytic iron or increase hepcidin might be beneficial in this patient population.
LCD codes and LCP of codes from units of group rings
Authors: KÖROĞLU Mehmet Emin
Published: February 2019

A linear code with complementary dual
(LCD) is a linear code such that  LCD codes are of great
importance due to their wide range of applications in consumer electronics,
storage systems and cryptography. Group rings have a rich source of units. Also
the well-known structural linear codes such as cyclic codes are within the
family of group ring codes. Thus, group rings offer an affluent source for
structural codes that may lead to linear codes with good properties. In this
work, we derive a condition for codes obtained from units of group rings to be
LCD. We show that a special decomposition of group rings meet the LCD
condition. We also proposed a consruction of linear complementary pair (LCP) of
codes.
