GRAMATICALIZAÇÃO DA PREPOSIÇÃO “PARA” NO PORTUGUÊS FALADO NO RIO DE JANEIRO
Authors: Guilherme Maurício Rubens de Carvalho
Published: April 2019

Resumo: O presente artigo tem como objetivo argumentar em favor de que a preposição para esteja passando por um processo de gramaticalização. Para tanto, baseia-se nos princípios estabelecidos por Meillet (1912), Kurylowicz (1965), Givón (1979), Lehmman (1982) e Heine (1993), os quais defendem que nesse processo estejam presentes fenômenos como, erosão fonética, coalescência, abstração e generalização; fenômenos que podem ser observados na preposição em análise. Com a finalidade de exemplificar e ratificar o argumento de que essa preposição está passando por um processo de mudança, foi feito um levantamento das ocorrências da citada preposição, em suas formas plena e reduzida, no corpus do projeto Norma Linguística Urbana Culta do Rio de Janeiro (NURC/RJ). O que se pôde concluir a partir dessa análise é que a redução da preposição mencionada é maior quando esta apresenta conteúdo semântico mais abstrato, ratificando a argumentação de que esteja ocorrendo um processo de gramaticalização.
NOME PRÓPRIO COMO LUGAR DE MEMÓRIA NA MÍDIA MINEIRA: REFLEXÕES SOBRE JORNAIS DE MARIANA
Authors: Landim Alessandra Folha Mós
Published: April 2019

Este trabalho tem como temática a ocorrência de nomes próprios em discurso(s) da mídia impressa marianense que remontam à memória de uma mineiridade imanente aos textos analisados. Um recorte de três jornais marianenses foi feito e, dentre eles, foram selecionados alguns excertos de diferentes textos jornalísticos que utilizam nomes próprios como lugares de memória das marcas de mineiridade que constituem esses jornais. O artigo passa por uma reflexão sobre a dimensão memorial que constitui o(s) discurso(s) para então abordar brevemente a temática da mineiridade, que é tomada sob o escopo da ordem do imaginário social. Articula tal noção à dimensão discursiva dos excertos analisados tomando os nomes próprios de mineiros, tais como Dom Silvério, Santos Dumont e Carlos Drummond de Andrade, como detentores de um sentido memorial que evoca valores constitutivos do imaginário de mineiridade.
LENIÇÃO E EPÊNTESE EM GRUPOS CONSONANTAIS TAUTOSSILÁBICOS NA LÍNGUA POLONESA FALADA EM CRUZ MACHADO, PR
Authors: Niewiadomski Sônia Eliane , Trennephol da Costa Luciane
Published: April 2019

O presente trabalho apresenta parte dos resultados de um estudo que objetiva descrever o polonês falado no interior do Paraná. Analisamos acusticamente os fenômenos de lenição e a inserção ou não da epêntese vocálica nos encontros de sons consonantais tautossilábicos, inexistentes no PB, como, por exemplo, “gdzie” [ɡd͡ʑɛ] (onde) no polonês falado em uma comunidade de descendentes no interior de Cruz Machado, PR, mais especificamente no Rio do Banho. A maioria destes descendentes é bilíngue (português/polonês) e, até os dias de hoje, têm como língua materna o polonês. Foram analisados dados de fala de oito informantes, sendo quatro homens e quatro mulheres, divididos em duas faixas etárias: de 25 até 40 anos e mais de 60 anos. A observação dos dados deu-se através de análise acústica e os resultados indicam a manutenção do sistema do polonês pelos descendentes. O estudo contribui para o conhecimento e registro desta língua brasileira.
Uma análise de uma tarefa avaliativa em uma sala de língua inglesa realizada colaborativamente
Authors: Oliveira Magalhães Victor Hugo
Published: April 2019

Este artigo investiga as implicações de se realizar uma tarefa avaliativa de maneira colaborativa em uma sala de aula de língua inglesa. Para tanto, usa-se como base o conceito vygotskyano de Zona de Desenvolvimento Proximal, o conceito de scaffolding de Wood, Bruner e Ross, e, finalmente, postulações de diversos autores sobre a aprendizagem colaborativa. Os dados deste artigo revelaram resultados positivos para além da mera execução da tarefa em questão: os alunos em ação colaborativa sentiram-se menos tensos e praticaram inglês entre eles durante a realização da atividade. Isso pode apontar para uma possível vantagem em se realizar avaliações colaborativamente, visto que a avaliação deve ser vista não apenas como medição de conhecimentos, mas promoção de aprendizagem.

Temporal Changes in Cardiac Troponin I Are Associated with Risk of Cardiovascular Events in the General Population: The Nord-Trøndelag Health Study
Authors: Lyngbakken Magnus N , Røsjø Helge , Holmen Oddgeir L , Dalen Håvard , Hveem Kristian , Omland Torbjørn
Published: April 2019

BACKGROUND

Cardiac troponins are associated with cardiovascular risk in the general population, but whether temporal changes in cardiac troponin I provide independent prognostic information remains uncertain. Using a large community-based cohort with follow-up close to the present day, we aimed to investigate the associations between temporal changes in cardiac troponin and cardiovascular events.

METHODS

We measured cardiac troponin I with a high-sensitivity assay (hs-cTnI) in 4805 participants attending both the second (HUNT 2, 1995–97) and third wave (HUNT 3, 2006–2008) of the prospective observational Nord-Trøndelag Health (HUNT) Study. We constructed statistical models with both relative and absolute changes of hs-cTnI from HUNT 2 to HUNT 3. A composite end point of cardiovascular death or first admission for myocardial infarction or heart failure was generated.

RESULTS

Participants with relative decrease in hs-cTnI were more frequently younger and female and had lower blood pressure and body mass index. Participants with relative increase in hs-cTnI more frequently were older and male, with higher systolic blood pressure. The adjusted hazard ratio (HR) for relative increase in hs-cTnI was 1.68 (95% CI, 1.16–2.42) and the adjusted HR for relative decrease was 1.19 (95% CI, 0.84–1.68). Absolute increases in hs-cTnI exhibited similar prognostic properties as relative increases in hs-cTnI. The most recent measurement of hs-cTnI outperformed the change variables in discrimination and reclassification models.

CONCLUSIONS

Both relative and absolute increases in hs-cTnI are independently associated with cardiovascular risk. For refinement of risk prediction models, the most recent measurement of hs-cTnI should be preferred in clinical practice.
Noncoding RNAs Serve as Diagnosis and Prognosis Biomarkers for Hepatocellular Carcinoma

Published: April 2019

BACKGROUND

Reliable noninvasive biomarkers for hepatocellular carcinoma (HCC) diagnosis and prognosis are urgently needed. We explored the potential of not only microRNAs (miRNAs) but other types of noncoding RNAs (ncRNAs) as HCC biomarkers.

METHODS

Peripheral blood samples were collected from 77 individuals; among them, 57 plasma cell-free RNA transcriptomes and 20 exosomal RNA transcriptomes were profiled. Significantly upregulated ncRNAs and published potential HCC biomarkers were validated with reverse transcription (RT)-qPCR in an independent validation cohort (60–150 samples). We particularly investigated the diagnosis and prognosis performance and biological function for 1 ncRNA biomarker, RN7SL1, and its S fragment.

RESULTS

We identified certain circulating ncRNAs escaping from RNase degradation, possibly through binding with RNA-binding proteins: 899 ncRNAs were highly upregulated in HCC patients. Among them, 337 genes were fragmented long noncoding RNAs, 252 genes were small nucleolar RNAs, and 134 genes were piwi-interacting RNAs. Forty-eight candidates were selected and validated with RT-qPCR, of which, 16 ncRNAs were verified to be significantly upregulated in HCC, including RN7SL1, SNHG1, ZFAS1, and LINC01359. Particularly, the abundance of RN7SL1 S fragment discriminated HCC samples from negative controls (area under the curve, 0.87; 95% CI, 0.817–0.920). HCC patients with higher concentrations of RN7SL1 S fragment had lower survival rates. Furthermore, RN7SL1 S fragment alone promoted cancer cell proliferation and clonogenic growth.

CONCLUSIONS

Our results show that various ncRNA species, not only miRNAs, identified in the small RNA sequencing of plasma are also able to serve as noninvasive biomarkers. Particularly, we identified a domain of srpRNA RN7SL1 with reliable clinical performance for HCC diagnosis and prognosis.
Sleeves and Kosodes: Gate of Hell/costume/fashion/history
Authors: Stutesman Drake
Published: April 2019

This article focuses on how the study of costume contributes to the interdisciplinary nature of fashion studies and film studies. How vital the study of costume is as intersection of history, fashion, politics, art and culture, can be answered through exploring the costumes in Kinugasa Teinosuke’s 1953 Japanese period film, Jigokumon (Gate of Hell) (1953). The reality that fashion, economies. technologies, inventions, identities and politics are inextricably entwined and that film costume must reflect that consolidation is complexly evident in the film.
Glamour studies: The state of the field
Authors: Gundle Stephen
Published: April 2019

This article, by the author of Glamour: A History in 2008, reassesses his own book and discusses the books of three other authors who in the last ten years have published analyses of glamour. Glamour in Six Dimensions in 2009, by Judith Brown, connects glamour to literary modernism, while Carol Dyhouse’s book Glamour: Women, History, Feminism (2010) provides a social history of feminine glamour in Britain, mainly between the 1920s and the 1960s. In The Power of Glamour in 2013, Virgina Postrel attempts to theorize glamour as a ‘non-verbal rhetoric’ centred on dreams of escape and transformation. Postrel’s argument is judged to be flawed in part because it lacks the materiality of Brown, the sharp gender focus of Dyhouse and the class-based historical approach of Gundle. It is argued that studies of glamour must start from what has generally been understood by the term. Theoretical advances may be achieved when social theory and material cultural approaches are more systematically brought together.
Ser Mexicano o Húngaro?
Authors: Csikós Zsuzsanna
Published: April 2019

The oeuvre of Susana Wein, Mexican writer of Hungarian origins often represents the controversial quest for identity carried out by immigrants and their descendants. The author proposes to examine these dilemmas of identity in Wein's collection of short stories En tiempo mexicano... cuentos húngaros (1985) and her novel titled La abuela me encargó a sus muertos (2005), both written in Spanish. The characters of Wein's prose enable the reader to follow the evolution and change of the problematics of identity from one generation to the next. For example, while the female protagonist of the short story Draga Rocza is proud of her Hungarian identity and is determined to preserve it, the heroine of Una historia de amor has ambitions of quick assimilation, motivated by social and individual interests. The narrator figure of the short story El día en que renuncié a mi nacionalidad presents the dilemma of second-generation immigrants born into a different culture. The author argues that the characters of Wein's novel undergo the same identity crisis: the grandmother's homesickness never seems to cease, the grandchild wants to return to her roots, and Uncle Isidor symbolizes the importance of remembering. Thus, Wein's prose offers a fusion of history and literature, filling the dry historical facts with life through her characters.
La recepción de la obra de Federico García Lorca en Hungría
Authors: Katona Eszter
Published: April 2019

In her essay, the author provides a thorough overview of the history of the reception of Federico García Lorca's poetry in Hungary. The 110th anniversary of Lorca's birth, commemorated this year, makes such surveys very timely. The author's aim is to examine Lorca's Hungarian presence from various perspectives. In the first phase of her recent investigations, she concentrated on presenting all the Hungarian translations and editions of Lorca's oeuvre. In the following, the Hungarian reception of Lorca's oueuvre is examined, based on essays and other writings of literary criticism of the era. The author also focuses on the different theatrical representations of Lorca's dramas in Hungary all over the 20th century, and the diverse articles and other press releases covering those. It is also important to mention that prior to the 1970s, there existed already a significant wave of investigations about the Spanish poet: Gábor Tolnai, László Péter, László András, János Benyhe and László Németh, amongst many, not only provided excellent translations of Lorca's poems but also carried out investigations of literary theory and history. Still, by the decade of the 1980s, the intensity of the academic and literary interest towards Lorca faded; the current anniversary provides both an occasion and a positive auspice for the continuation of this work.
Aspecto verbal en la evolución de la construcción catalana "anar + infinititu"
Authors: Nagy Katalin C.
Published: April 2019

The paper presents the special characteristics of the Catalan past perfect tense. In the majority of languages, and, more specifically, in neo-latin languages, similar structures, containing verbs of movement tend to modify into future tense. As opposed to this, the structure“anar + infinitive” stands for past perfect in modern Catalan. The perfect aspect component raises the question of how this tense became grammaticized, a process examined by the author from the historic pragmatic point of view. There are two main hypotheses concerning the aspect of the medieval antecedent of the structure. According to the so-called inchoative hypothesis, the medieval “anar + infinitive” was an inchoative periphrasis. The other thesis attributes past perfect quality to the structure already in medieval Catalan. The perfect aspect can be traced back either to the verbal aspect of the auxiliar verb in past perfect, rather common in medieval Catalan structures, or, in earlier sources, to the lexical aspect of perfect-aspect verbs in the structure. The author employs two main lines of methodology: on the one hand, the phenomenon is analyzed in correlation with structures similar either in form or function; on the other hand, it considers the more ample context of medieval use. The author concludes that the modern Catalan past perfect is not rooted in an inchoative periphrasis, but evolved from a compound structure expressing intention, which probably gave rise to pragmatical conclusions in its contexts of use. As a result of these pragmatical conclusions, the meaning of the structure transformed from a structure with a perfect or completive aspect into the past perfect tense of modern Catalan.
La represión de lo imaginario en el campo literario Mexicano del siglo XX
Authors: Vélez García Juan Ramón
Published: April 2019

This work seeks to study, within the Mexican literary field of the XXth century, the situation
of some authors who have been segregated from it because of their refusal to yield their work to
the requirements of nationalistic themes. I’m going to take as examples of the aforementioned
ideas two illustrative cases: the authors who were members of the group Contemporáneos (such
as Xavier Villaurrutia, José Gorostiza, Jorge Cuesta, Gilberto Owen, Salvador Novo…)
and the writer Francisco Tario (pseudonym adopted by Francisco Peláez).
El nudo/nodo en la narrativa de Julio Cortázar y Los caminos hacia la hiperficción
Authors: Llosa Sanz Álvaro
Published: April 2019

The word nudo (knot), which comes from the latin nodus, is explained in seventeen
different ways in the Dictionary published by the Spanish Royal Academy. However, every
definition converges in a key point: the knot as a juncture or convergence of diverse elements. In
this paper, I apply these definitions to the analysis of knot and nodal methaporic structures
used in Julio Cortázar’s narrative: the knot starts as a literary metaphor in his early work
titled Divertimento (1949), it evolves into a nodal structure in Rayuela (1963), and
finally it reachs a maximum complexity of knots and nodes in 62, modelo para armar
(1968).
Teoría y práctica del cine "nacional" en la guerra civil española
Authors: Lénárt András
Published: April 2019

The insurgent army of the Spanish extreme right took advantage of the power of cinema, just like
other European leaders did in the 20Th centuiy. Between 1936 and 1939 (and during the whole
regime as well) Spanish screens were spread with nationalist visual propaganda in order to shape the
course of public opinion and to implant the ideology of the Falangist Movement in the citizens. General
Franco, his confidants and even his relatives exercised tight control over film politics, giving preference to
short films, documentaries and newsreels. In this essay we examine the theoretical and industrial
background of the incipient francoist film politics during the Civil War and we highlight some of the
most important products of this effort , briefly touching upon a few relevant international matters, such
as the anti-Franco movement of Hollywood or the German and Italian support.
En busca del concepto de cine nacional Español
Authors: Lénárt András
Published: April 2019

The aim of this paper is to analyse the notion of Spanish "national dnema" from a
chronological perspective and to search for a possible answer to the question if there is a reason
to reflect on this expression in case of Spain. Since the arrival of the dnematograph at the
peninsula, the theoretical approaches ofpoliticans, ideologists and filmmakers to this problem
have produced a wide range of movies which have given a subjective perception about some
authentic or false characteristics of the Spaniards. The consecutive administrations had different
and often inconsistent attitudes towards their own national dnematographic representation:
while the Second Republic practically neglected the shaping of this audiovisual self-definition,
the Franco regime laid by far the largest emphasis on creating the ultimate patriotic national
dnema. Nowadays it is even more complicated, if not impossible, to identify the nature of the
contemporary Spanish national film industry. We will touch upon genres, movies, stereotypes,
personal impressions and ideological argumentations in order to examine what national dnema
means in the Spanish context.

The crucial tools and the core of our arguments are Hilbert complexes and related compact embeddings.
The disordered boundary of the cell: emerging properties of membrane-bound intrinsically disordered proteins
Authors: Mohammad Irrem-Laareb , Mateos Borja , Pons Miquel
Published: April 2019

We define the disordered boundary of the cell (DBC) as the system formed by membrane tethered intrinsically disordered protein regions, dynamically coupled to the underlying membrane.

The emerging properties of the DBC makes it a global system of study, which cannot be understood from the individual properties of their components. Similarly, the properties of lipid bilayers cannot be understood from just the sum of the properties of individual lipid molecules.

The highly anisotropic confined environment, restricting the position and orientation of interacting sites, is affecting the properties of individual disordered proteins. In fact, the collective effect caused by high concentrations of disordered proteins extend beyond the sum of individual effects.

Examples of emerging properties of the DBC include enhanced protein-protein interactions, protein-driven phase separations, Z-compartmentalization, and protein modulated electrostatics.
Energy storage analysis of R125 in UIO-66 and MOF-5 nanoparticles: A molecular simulation study
Authors: Wang Qiang , Tang Shengli
Published: April 2019

The efficiency of thermodynamic cycles can be improved by using the optimized working fluid. In the present paper, classic molecular dynamics simulations and grand canonical Monte Carlo were employed to examine the thermal energy storage characteristicsof R125/UIO-66 and R125/MOF-5 nanofluids. The results indicate that the adsorption of R125 in MOF-5 is larger than that in UIO-66. Also, the thermal energy storage capacity of R125 was strengthened by mixing with UIO-66 or MOF-5 nanoparticles. In addition, the R125/UIO-66 mixtures can store less energy than that of R125/MOF-5 mixtures except the temperature difference is 30 K to 50 K.
Cryptanalysis of a hash function, and the modular subset sum problem
Authors: Monico Chris
Published: April 2019

Recently, Shpilrain and Sosnovski proposed a hash function based on composition of affine maps.
In this paper, we show that this hash function with its proposed parameters is not
weak collision resistant, for plaintexts of size at least 1.9MB (about {2^{24}} bits).
Our approach is to reduce the preimage problem to a (very) high density instance of the
Random Modular Subset Sum Problem, for which we give an algorithm capable of solving instances of the resulting size.
Specifically, given plaintexts of about 1.9MB, we were able to produce other plaintexts of the same size with the same hash value in about 13 hours each, on average.
An improved version of the AAG cryptographic protocol
Authors: Roman’kov Vitaliĭ
Published: April 2019

An improved version of the Anshel–Anshel–Goldfeld (AAG) algebraic cryptographic key-exchange scheme, that is in particular resistant against the Tsaban linear span cryptanalysis, is established. Unlike the original version, that is based on the intractability of the simultaneous conjugacy search problem for the platform group, the proposed version is based on harder simultaneous membership-conjugacy search problems, and the membership problem needs to be solved for a subset of the platform group that can be easily and efficiently built to be very complicated and without any good structure. A number of other hard problems need to be solved first before start solving the simultaneous membership-conjugacy search problem to obtain the exchanged key.
Vimentin is required for normal accumulation of body fat
Authors: Wilhelmsson Ulrika , Stillemark-Billton Pia , Borén Jan , Pekny Milos
Published: April 2019

Intermediate filaments (nanofilaments) have many functions, especially in response to cellular stress. Mice lacking vimentin (Vim
−/−) display phenotypes reflecting reduced levels of cell activation and ability to counteract stress, for example, decreased reactivity of astrocytes after neurotrauma, decreased migration of astrocytes and fibroblasts, attenuated inflammation and fibrosis in lung injury, delayed wound healing, impaired vascular adaptation to nephrectomy, impaired transendothelial migration of lymphocytes and attenuated atherosclerosis. To address the role of vimentin in fat accumulation, we assessed the body weight and fat by dual-energy X-ray absorptiometry (DEXA) in Vim
−/− and matched wildtype (WT) mice. While the weight of 1.5-month-old Vim
−/− and WT mice was comparable, Vim
−/− mice showed decreased body weight at 3.5, 5.5 and 8.5 months (males by 19–22%, females by 18–29%). At 8.5 months, Vim
−/− males and females had less body fat compared to WT mice (a decrease by 24%, p < 0.05, and 33%, p < 0.0001, respectively). The body mass index in 8.5 months old Vim
−/− mice was lower in males (6.8 vs. 7.8, p < 0.005) and females (6.0 vs. 7.7, p < 0.0001) despite the slightly lower body length of Vim
−/− mice. Increased mortality was observed in adult Vim
−/− males. We conclude that vimentin is required for the normal accumulation of body fat.
Prototypical influence in second language acquisition: What now for the Aspect Hypothesis
Authors: McManus Kevin
Published: April 2019

This paper presents empirical evidence on the development of aspect by English- and German-speaking university learners of French L2 collected from a spoken narrative task and a sentence interpretation task. Contrary to the Aspect Hypothesis's predictions, this study's results suggest that increased use of prototypical pairings goes in hand with increased L2 proficiency. Following a small but growing number of studies, this study questions the route of L2 development proposed by the Aspect Hypothesis.
Influence of learners’ prior knowledge, L2 proficiency and pre-task planning on L2 lexical complexity
Authors: Bui Gavin
Published: April 2019

Although differentiating between fluency, accuracy and complexity, while assessing L2 task performance, is becoming a standard practice, lexical complexity as a distinctive area has received less attention in the task-based language teaching (TBLT) literature. This study re-examines previous frameworks of lexical complexity and investigates three lexical dimensions,lexical diversity, lexical sophisticationandlexical density, using a structured 2 × 2 × 2 split-plot experimental design. The participants were divided into a non-planning group and a planning group and each group was further dichotomised into two proficiency levels. Each participant was assigned one familiar and one unfamiliar oral narrative task. The results show that one’s prior knowledge about a subject is associated with higher lexical diversity and sophistication, while pre-task planning promotes lexical density. The effects of proficiency seem to be largely overridden by the effects of prior knowledge and pre-task planning and show little impact on overall lexical performance. Interestingly, lexical diversity and lexical sophistication are independent of each other, and lexical density is moderately correlated with both lexical diversity and lexical sophistication. The results are discussed with reference to the Levelt model of speech production with some pedagogical implications on content-based language instruction. The exploration of the relationships between the lexical measures reveals a need for deeper and subtler characterisation of L2 lexical complexity.
Inverse Sturm–Liouville problems for non-Borg conditions

We consider Sturm–Liouville problems on the finite interval with non-Borg conditions.
Using eigenvalues of four Sturm–Liouville problems, we construct the spectral data and show that the mapping from potential to spectral data is a bijection.
Moreover, we obtain estimates of spectral data in terms of potentials.
Two-sided altruism and time inconsistency
Authors: Aoki Takaaki , Nishimura Kazuo , Yano Makoto
Published: April 2019

In this study, we examine dynamic allocation of resources and consumption over an infinite time horizon in an overlapping-generations model with two-sided altruism. Each generation cares not only about its own consumption and the utility of its successor, but also about the utility of its parental generation. The consumption decisions of different generations could display time-inconsistency in a model of two-sided altruism. Consequently, the outcome solutions could differ depending on whether members of the current generation are naïve and falsely believe that the future generation will comply with their, or are sophisticated and know exactly how the future generation will choose to behave. We assume that the young generation is naïve and behaves as a central planner in allocating capital resources. The capital stocks inherited by each generation from the parental generation are actually realized and used in the joint production of capital stocks and consumption goods. We refer to a sequence of such capital stocks as a two-sided altruistic path. This study examines a more general production function than earlier models of two-sided altruism, and our results prove that any two-sided altruistic path will eventually converge to the two-sided altruistic stationary path.
Anticipatory Syncopation in Rock: A Corpus Study
Authors: Tan Ivan , Lustig Ethan , Temperley David
Published: April 2019

While syncopation generally refers to any conflict between surface accents and underlying meter, in rock and other recent popular styles it takes a more specific form in which accented notes occur just before strong beats. Such “anticipatory” syncopations suggest that there is an underlying cognitive representation in which the accented notes and strong beats align. Syllabic stress is crucial to the identification of such syncopations; to facilitate this, we present a corpus of rock melodies annotated with lyrics and syllabic stress values. We propose a new measure of syncopation that incorporates syllabic stress; we also propose a measure of anticipatory syncopation, and show that it reveals a strong presence of this type of syncopation in rock music. We then use these measures to explore other aspects of syncopation in rock, including its occurrence in different parts of the 4/4 measure, its dependence on tempo, its historical evolution, and its aesthetic functions.
Empathy, Entrainment, and Perceived Interaction in Complex Dyadic Dance Movement
Authors: Carlson Emily , Burger Birgitta , Toiviainen Petri
Published: April 2019

The current study explores how individuals' tendency to empathize with others (trait empathy) modulates interaction and social entrainment in dyadic dance in a free movement context using perceptual and computationally derived measures. Stimuli consisting of 24 point-light animations were created using motion capture data selected from a sample of 99 dyads, based on self-reported trait empathy. Individuals whose Empathy Quotient (EQ) scores were in the top or bottom quartile of all scores were considered to have high or low empathy, respectively, and twelve dyads comprised of four high-high, four low-low, and four high-low empathy combinations were identified. Animations of these dyads were presented to 33 participants, who rated the degree of interaction and movement similarity for each stimulus. Results showed a significant effect of empathy combination on perceived interactivity and perceived similarity. High-low stimuli were rated as significantly more interactive than either high-high or low-low stimuli, while high-high stimuli were rated as significantly less similar than high-low and low-low. Dyads’ period-locking, bodily orientation and amount of hand movement were all significantly correlated with rated amount of interaction, while rated similarity only related significantly to period-locking. Results suggest that period-locking is important for social entrainment to be perceived, but that other signals such as bodily orientation and hand movement also signal social entrainment during free dance movement.
The Determinants of Corporate Dividend Policy in Poland
Authors: Rój Justyna
Published: April 2019

[full article and abstract in English]

The purpose of this research is to examine the factors that determine the dividend policy of non-financial firms listed on the Warsaw Stock Exchange (WSE) in Poland and that of the annually paid dividends. Up to now, many empirical studies related to dividend policy were carried out, showing the differentiation of factors affecting the dividend policy and their interaction. Thus, with this study, it would be possible to give a view on the dividend policy of corporations listed on the WSE for the period from 2008 to 2016. The study covers non-financial companies listed on the WSE in Poland. The Tobit regression is used to identify the impact of factors influencing the companies’ distribution of dividends. The variables that may explain a firm’s dividend decision and that were used in this study are selected based on the theory and available empirical researches and then also determined by data availability. These are profitability, investment opportunities, measures of size, leverage, and liquidity. As a result of this study, the factors that determine the dividend policy of companies were verified in the context of the companies listed on the WSE. Moreover, it indicates which of the existing theories on dividend policy could be applied to the capital markets of Poland. Thus, it provides new insights into the theory of dividend policy.
Solution Processing of V2O5-WO3 Composite Films for Enhanced Li-Ion Intercalation Properties
Authors: Cai Chuan , Guan Dongsheng , Wang Ying
Published: April 2019

We have employed a simple and novel solution processing method to prepare V2O5-WO3 composite films which demonstrate enhanced Li-ion intercalation properties for applications in lithium-ion batteries. It should be noted that this solution processing method employs precursors that only contain the elements of V, W, O and H, which avoids impurity elements such as Na that has been commonly used in other solution methods. The V2O5-WO3 composite films show enhanced Li-ion intercalation properties compared to pure V2O5 and WO3 films. For example, V2O5-WO3 film with a molar ratio V2O5/WO3 of 10/1 exhibits a discharge capacity of 254 mA•h/g, while the pure V2O5 film delivers a discharge capacity of 76 mA•h/g at a high current density of 1.33 A/g. Such enhanced Li-ion intercalation properties are attributed to the reduced crystallinity and increased porosity and surface area in the composite films. In addition, the chronopotentiometric curves of the V2O5-WO3 film with a mol ratio of 10:1 are distinctively different from those of pure oxide films and other composite films with different V2O5/WO3 mol ratios, suggesting a different Li-ion intercalation process in the V2O5-WO3 film with the mol ratio of 10/1.
Enhanced Absorption in Amorphous Silicon Solar Cells Using Plasmonic and Photonic Crystals – Measurement and Simulation
Authors: Curtin Benjamin , Biswas Rana , Dalal Vikram
Published: April 2019

We develop experimentally and theoretically plasmonic and photonic crystals for enhancing thin film silicon solar cells. Thin film amorphous silicon (a-Si:H) solar cells suffer from decreased absorption of red and near-infrared photons, where the photon absorption length is large. Simulations predict maximal light absorption for a pitch of 700-800 nm for photonic crystal hole arrays in silver or ZnO/Ag back reflectors, with absorption increases of ~12%. The photonic crystal improves over the ideal randomly roughened back reflector (or the ‘4n2limit’) at wavelengths near the band edge. We fabricated metallic photonic crystal back-reflectors using photolithography and reactive-ion etching. We conformally deposited a-Si:H solar cells on triangular lattice hole arrays of pitch 760 nm on silver back-reflectors. Electron microscopy demonstrates excellent long range periodicity and conformal a-Si:H growth. The measured quantum efficiency increases by 7-8 %, relative to a flat reflector reference device, with enhancement factors exceeding 6 at near-infrared wavelengths. The photonic crystal back reflector strongly diffracts light and increases optical path lengths of solar photons.
Microwave Absorption of Magnetic Antidot Arrays

Published: April 2019

Three antidot arrays with FeNi alloy thickness of 20, 50 and 100 nm have
been patterned using magnetron sputtering followed by the electron-beam
lithography and lift-off technique. Ferromagnetic resonance technique was
used to study dynamic properties of the antidot arrays. These results were
compared with the measurements of continuous films with the same composition
and thickness. Two distinct resonant fields have been observed for the bias
field aligned with the edges of the square holes. Resonance peaks shifted
towards each other and eventually merged when the in-plane bias field was
rotated towards diagonal of the squares. This dependence has been explained
in terms of magnetostatic energy associated with the square holes. The
magnitude of this effect was decreasing for the arrays with the reduced
thickness. The perpendicular and lateral quantized standing spin wave modes
were detected in the reference films and the antidot arrays due to the
perpendicular and lateral dimensional confinements.

This article was migrated. The article was marked as recommended. BackgroundAn asynchronous curriculum is one in which residents complete structured learning assignments outside of the traditional Emergency Medicine conference day. As educators are challenged with filling the time in the traditional didactic classroom setting with appropriate content while maintaining the interest of learners, asynchronous learning is becoming an essential component of Emergency Medicine resident curricula. While many residencies are investigating best practices to design and implement asynchronous education, relatively little guidance exists on the creation of such a curriculum.MethodsOur goal was to create an asynchronous curriculum using only a chief resident and a core faculty member. Our module-based asynchronous curriculum was formulated based on recommendations from the Council of Emergency Medicine Residency Directors (CORD) (Sadosty et al. 2009). We focused on using free open access medical education (FOAMEd) as primary content.ResultsOur residency program has successfully implemented an asynchronous curriculum for two years, and it is still ongoing. We achieved an assignment completion rate of 77.0% in the first year of implementation and 88.6% in our second year.ConclusionsThe creation and implementation of an asynchronous curriculum is manageable and well-received by Emergency Medicine residents.
Diferenciais de Participação Laboral e Rendimento por Gênero e Classes de Renda: uma Investigação sobre o Ônus da Maternidade no Brasil
Authors: Muniz Jerônimo Oliveira , Veneroso Carmelita Zilah
Published: April 2019

Resumo As desigualdades na distribuição de renda, assim como a influência do número de filhos sobre a participação de homens e mulheres no mercado de trabalho são assuntos pouco explorados no Brasil. Este artigo investiga o efeito da maternidade na probabilidade de a mulher estar ou não inserida no mercado de trabalho e mensura os diferenciais de rendimento entre homens e mulheres, por classes de renda, controlando-se pelo viés de seleção ocupacional, pelos diferenciais de capital humano e pelo número de crianças presentes no domicílio. Conclui-se que há severa penalidade materna para a inserção das mulheres pobres no mercado de trabalho, mas que a maternidade não é o principal fator que influencia o hiato sexual de rendimentos. Além disso, demonstra-se que a desigualdade de renda é favorável aos homens que se encontram nas classes baixa e média, mas não entre os mais ricos.

ABSTRACT Objective: identify delirium and subsyndromal delirium in intensive care patients; age, hospitalization time, and mortality. Method: a retrospective, quantitative study conducted in the Intensive Care Unit, using the Richmond Agitation-Sedation Scale to evaluate sedation and the Intensive Care Delirium Screening Checklist for the identification of delirium, with the participation of 157 patients. For statistical analysis, the t-test and the Chi-square test was carried out. Results: the majority presented subsyndromal delirium (49.7%). Mortality was 21.7%. The relationship between delirium and its subsyndromal with hospitalization time was statistically significant for both (p=0.035 and p <0.001), while age was significant only in the subsyndromal delirium (p=0.009). Conclusion: the majority of the patients presented subsyndromal delirium. The length of hospital stay was statistically significant in delirium and subsyndroma delirium. Age was significant only in subsyndromal delirium. The mortality of patients with delirium was higher than the others.

Published: April 2019

ABSTRACT Objective: To translate and adapt the Patient Perceptions of Hemodialysis Scale (PPHS) to the Brazilian context. Method: A methodological study, in which the stages of initial translation, synthesis of translations, back translation, evaluation by an expert committee and pre-test of the PPHS were performed. Results: Two initial translations by independent translators, experienced in the health area and fluent in English. Subsequently, the synthesis of the translations was carried out, and this synthesis was back translated to the original language (American English).The translated and back-translated versions were evaluated by an expert committee made up of six PhD experts from the health area. The judges’ evaluations resulted in content validity indexes for each item of the scale, and 7 of the 36 items had to be revised. Subsequently, a pretest was carried out with 20 participants, who considered the instrument intelligible. Conclusion: The PPHS is adequately translated and adapted to Brazilian Portuguese.

ABSTRACT Objective: To analyze the network of human and non-human actors involved in the computerization of primary health care in the Brazilian federal government. Method: A qualitative study that used as a theoretical reference the actor-network theory and as a methodological reference the cartography of controversies. Data analysis was carried out using Gephi software, and through the extraction of reports, informed by the actor-network theory. Results: We found a network of 288 connections among 33 actors, composed mainly of nonhuman influencers of computerization. These actors are distributed throughout 3 inter-related communities, and manage the network by defining obligations, penalties, conflicts and intentionalities, thus influencing the success of the intended computerization. Final considerations: The network of actors at the federal level generates situations that, in many cases, hamper the successful implementation of a nationwide computerization strategy.

Published: April 2019

ABSTRACT Objective: To evaluate the satisfaction index of the pediatric patient’s caregiver (person responsible for the child) regarding the waiting time for the care flow in an emergency service. Method: A prospective, cross-sectional, quantitative study with 300 family members in the Pediatric Emergency Department of a general hospital. An instrument was used to analyze the service flow, waiting time and satisfaction evaluation. Descriptive statistical analysis was performed. Results: The satisfaction index of caregivers was statistically significant (p<0.05) the lower was the waiting time for patient screening, care by the doctors and for receiving the prescribed medication. Caregivers who took their children to the emergency department because of the disease (p -0.029) or because they did not find doctors in other hospitals (p-0.021) were satisfied with the waiting time for this service. Conclusion: The quality of care is evaluated as satisfactory by caregivers when children are treated quickly in the Pediatric Emergency Department.

Published: April 2019

ABSTRACT Objective: to know the conceptions of nurse midwives about the care guided in the best practices to the women in the delivery process. Method: descriptive research with a qualitative approach developed in a Federal Maternity-School. Semi-structured interviews were conducted with 20 nurse midwives, and the speeches were categorized according to the thematic content analysis proposed by Franco. Results: the study reveals that care based on best practices should be based on scientific knowledge, avoiding unnecessary interventions and encourages the use of non-pharmacological techniques for pain relief, appropriate environment, individualized care, the bond between professional and parturient, as well as its role. Final Consideration: while criticizing the excess of interventions, nurse midwives value noninvasive techniques and interpersonal relationships, as well as the subjectivities of the parturient that contributes to the humanized care in the delivery process.
