Inference of Historical Population-Size Changes with Allele-Frequency Data
Authors: Lynch Michael , Haubold Bernhard , Pfaffelhuber Peter , Maruki Takahiro
Published: November 2019

With up to millions of nearly neutral polymorphisms now being routinely sampled in population-genomic surveys, it is possible to estimate the site-frequency spectrum of such sites with high precision. Each frequency class reflects a mixture of potentially unique demographic histories, which can be revealed using theory for the probability distributions of the starting and ending points of branch segments over all possible coalescence trees. Such distributions are completely independent of past population history, which only influences the segment lengths, providing the basis for estimating average population sizes separating tree-wide coalescence events. The history of population-size change experienced by a sample of polymorphisms can then be dissected in a model-flexible fashion, and extension of this theory allows estimation of the mean and full distribution of long-term effective population sizes and ages of alleles of specific frequencies. Here, we outline the basic theory underlying the conceptual approach, develop and test an efficient statistical procedure for parameter estimation, and apply this to multiple population-genomic datasets for the microcrustacean Daphnia pulex.

Authors: Bohnhoff James C. , Taormina Jill M. , Ferrante Lorraine , Wolfson David , Ray Kristin N.
Published: November 2019

OBJECTIVES:

Incomplete subspecialty referrals, whether unscheduled or unattended, represent unmet patient needs and an opportunity to improve patient safety and experiences. Our objectives were to describe the rates of appointment scheduling and visit attendance after pediatric subspecialty referral and to examine patient and systems factors associated with scheduled referrals and attended appointments.

METHODS:

We conducted a retrospective review of referrals within a network of 52 primary and urgent care sites from November 2016 to October 2017. We included referrals for children ≤17 years old referred to medical or surgical subspecialists. We examined patient and health systems factors associated with (1) appointment scheduling and (2) visit attendance.

RESULTS:

Of 20 466 referrals, 13 261 (65%) resulted in an appointment scheduled within 90 days and 10 514 (51%) resulted in a visit attended within 90 days. In adjusted analyses, referral to surgical subspecialists was associated with an increased likelihood of appointment scheduling but a decreased likelihood of visit attendance. Compared with appointments scheduled within 7 days, appointments with intervals from referral to scheduled appointment exceeding 7 days were associated with decreasing likelihood of visit attendance (adjusted odds ratio 8–14 days 0.48; 95% confidence interval 0.37–0.61). Patient factors associated with decreased likelihood of both appointment scheduling and visit attendance included African American race, public insurance, and lower zip code median income.

CONCLUSIONS:

Patient and system factors were associated with variation in appointment scheduling and visit attendance. Decreased interval to appointment was significantly associated with visit attendance. These factors represent targets for interventions to improve referral completion.
Cryptic molecular diversity in the morphologically variable rotiferan Brachionus quadridentatus (Rotifera: Monogononta)
Authors: Garcia-Morales Alma E. , Domínguez-Domínguez Omar
Published: November 2019

Brachionus quadridentatus is a morphologically variable species distributed worldwide. Its taxonomy is confusing due the numerous infrasubspecific variants described in the taxon. Here we explore genetic diversity of certain B. quadridentatus populations, using sequences of COI mtDNA and 18S rDNA genes. With traditional morphology (taxonomic keys), the specimens identified fell into three recognized variants: B. quadridentatus quadridentatus, B. quadridentatus f. brevispinus and B. quadridentatus f. cluniorbicularis. The coalescent species delimitation analysis highly supports the presence of at least three putative species within B. quadridentatus complex in agreement with the phylogenetic result and GMYC analysis with the 18S gene. Nevertheless, the morphological and mitochondrial information show that the variation within each of the three putative species is much more extensive, finding seven monophyletic and highly divergent genetic groups (>10%) that have congruence with the morphotypes found in this study and ABGD analysis, which display clear morphological differences mainly in the diagnostic characters.

Authors: Antunes Altamir Rocha , Elias Guilherme Alves , Pezente Gisele , Santos Robson
Published: November 2019

Inga Mill. belongs to mimosoid clado (Fabaceae, Caesalpinioideae) with 131 species in Brazil. It is the most expressive genus of Fabaceae. This study aimed to perform a bibliometric analysis on Inga from Santa Catarina state. A survey of the published literature was conducted using the electronic databases of the Web of Science, Scopus and Scielo, with the accepted names of Inga species and its synonyms. Papers were distributed in four subject categories: C1 (Ecological), C2 (morphology, anatomy, histology, physiology and genetics), C3 (production and use) and C4 (biochemical and nutritional properties). We registered 232 papers for 13 species of Inga, exhibiting remarkable growth over time. C1 was the most expressive subject category, mainly by nutrient supply, shading and nitrogen fixing capacity. The subjects diversifying over the years, with registered papers in all categories. Inga edulis, I. vera and I. marginata were the most registered species in our survey. We did not find papers on I. edwallii, I. sellowiana and I. vulpina. Our results showed an increase in the number of articles on Inga over time, especially in the last 13 years. However, some important gaps need to be addressed, such as the relatively small number and/or lack of studies conducted for some species.

Published: November 2019

This study represents the comprehensive screening of allelopathic activity of weeds in Pakistan by applying sandwich and dish pack methods. The source for existing research of weed control towards classifying the potent organic compounds for controlling weeds in crops is the screening of large quantities of plants. Strong allelopathic weeds species have been acknowledged from analysis to provide direction for further research. Under laboratory conditions 73 weeds species were examined for their allelopathic potentials through latest bioassay activity evaluation techniques. The research information generated from the present work can be used as a benchmark for future research on the allelochemical identification and characterization. During the follow up work of present endeavor; methanolic leaf extracts of strongest allelopathic species shall be tested for antioxidant activities on crops pathogens and will also be recommended as allelopathic cover crop for biological control of weeds to support agro-environment conservation. In Pakistan, the allelopathic activity evaluation of plants through bioassay techniques is quite rare. There is a dire need to develop a complete data base of plants having strong allelopathic potential through application of these latest techniques.
Projected impact of global warming on the distribution of two pocket mouse species with implications on the conservation of Heteromys nelsoni (Rodentia: Heteromyidae)
Authors: Lorenzo Consuelo , Carrillo-Reyes Arturo , Rioja-Paradela Tamara , Sántiz-López Eugenia , Bolaños-Citalán Jorge
Published: November 2019

We explain through potential distributions and changes in altitudinal variation, the possible impacts of climate change in an endangered micro-endemic rodent of Mexico with narrow altitudinal range, Heteromys nelsoni and a rodent with a wide distributional and altitudinal range, Heteromys goldmani. We obtained historical and current records of both Heteromys species. Potential distribution models were generated using Maxent, including altitudes for each species and bioclimatic layers. We determined the Extent of Occurrence and Area of Occupancy for H. nelsoni according to the criteria of the IUCN in order to generate information about its risk status. The altitude is not a variable that determines a shift in the distribution caused by climate change. In contrast, the temperature and precipitation are important for the potential distribution of both Heteromys species. The future changes in climatic conditions will reduce the area of suitable habitat for H. nelsoni and will favor the presence of H. goldmani. The distribution surface is not greater than 33.44 km2 for H. nelsoni. Therefore, is urgent to re-evaluate their conservation status by the IUCN, mainly in its B criterion, and to take specific actions for their conservation. We suggest the creation of a terrestrial protected area.

Introducción: La diversidad de macro-artrópodos está relacionada con el estado de conservación del suelo, por lo tanto, el cambio de uso del suelo afecta su integridad. Una estrategia para la conservación de estos organismos es la implementación de sistemas de producción diversificados como los sistemas silvopastoriles; no obstante, en el sureste de México la información aún es limitada. Objetivo: El propósito del presente estudio fue evaluar y comparar la riqueza y la abundancia de macro-artrópodos en cuatro agro-ecosistemas contrastantes: dos sistemas silvopastoriles conformados por Leucaena leucocephalay pastos asociados (i.e. Panicum maximumcv mombaza y Cynodon plectostachyus), un pastizal convencional de Brachiaria brizanthacon árboles dispersos y una selva mediana subperennifolia. Métodos: Se utilizaron trampas pit-fall de un litro de capacidad y un diámetro de 14.4 cm. Los muestreos se realizaron en dos periodos: uno en el mes de febrero y otro en el mes de mayo del 2018, en cada mes se hicieron cinco colectas espaciadas, lo que hizo un total de 100 muestras. Resultados: Se recolectaron un total de 1 737 organismos pertenecientes a 14 especies de 11 órdenes. Los sistemas con mayor abundancia de macro-artrópodos fueron, el sistema de selva media subperennifolia (923 individuos) y el sistema silvopastoril de L. leucocephalacon C. plectostachyus(354 individuos). Los órdenes más abundantes fueron: Hymenoptera, Coleoptera, Aracnidos y Orthoptera.La mayor diversidad de macro-artrópodos se presentó en los sistemas silvopastoriles de L. leucocephalacon P. maximum(H’=1.586) y L. leucocephalacon C. plectostachyus(H´=1.441). Conclusiones: Los resultados encontrados muestran que los sistemas pecuarios manejados con componentes leñosos (árboles/arbustos) pueden equipararse, en términos de abundancia y diversidad de órdenes de macro-artrópodos, con sistemas como las selvas o bosques, lo cual contribuye a la integridad y funcionalidad de los agro-ecosistemas.

Um turista bem moderno: a expressão amazônica de Mário de Andrade na literatura e na fotografia
Authors: Langfeldt Marcia Caetano
Published: November 2019

Mário de Andrade (1893-1945) was a Brazilian poet, novelist, literary critic, ethnographer, musicologist, art critic as well as a competent photographer and a dedicated researcher of Brazilian folklore. In 1927, he travelled to the Amazon together with three female friends. During this trip, he published a series of articles in a national newspaper, wrote two diaries, collected notes and finished his most important book, Macunaima, considered the reference of Brazilian Modernism. In addition to that, he took more than 500 photos of the journey, most of them in a very modern perspective. This paper investigates to what extent these various representations of the Amazon contribute to Mario de Andrade’s aesthetic project, as a Brazilian intellectual from the first quarter of the twentieth century,
La littérature à l'épreuve du réel : les jeux de Pascal Quignard avec les Lettres
Authors: Martin Xavier
Published: November 2019

The novel Les Larmes, by French writer Pascal Quignard, takes place in the ninth century, two twin brothers make totally different choices of life. Hartnid is always on the go. His twin, Nithard, is a pure scholar. His life is devoted to language. It is precisely his involment in language that allows him to write something that was never written before. He writes the Serments de Strasbourg (English: Oaths of Strasbourg, Latin: Sacramenta Argentariae) in 842, first written marks of a language that will become the French language.

This novel offers a unique opportunity to sketch a thought on the ability of literature to speak about our relationship to reality.  

The first part of the article questions the gesture of the novelist who acts on himself and on reality when writing, he really tries to change the world.

The second part of the article studies the notion of realism and shows how Quignard finds a place in the history of literature that, today, stays away from realism, but, maybe, in order to better track down reality.

Finally, in order to grasp the specificity of the Works of Quignard, my interest in the aesthetic of Les Larmes is threefold: its complex structure, the fascination for origin that it shows and, the question of identity and splitting with the twin brothers Hartnid and Nithard.

The article concludes on the ability of artists to anticipate in their creations and, in advance, to tell about events that will occur in the future.
La fonction communicative d’énoncés déclaratifs utilisés dans l’interrogation totale ‒ une étude contrastive français/norvégien
Authors: Hobæk Haff Marianne
Published: November 2019

This paper discusses the communicative function of declarative sentences used as polar questions in French and Norwegian:

(1a) - Inger Holter jobbet i en bar?

(1b) -  Inger Holter bossait dans un bar ?

These two sentences are similar concerning the subject-verb order, the ascending intonation curve, and the choice of lexical morphemes. In both languages, they are declarative sentences used to ask questions. More precisely, we are dealing with polar questions marked by intonation only.

The way sentences such as (1a) and (1b) are used in actual texts shows that they do not have the same communicative function. The Norwegian speaker expects his assumption to be confirmed by the listener, maybe with a hope of getting more information. The French example, on the other hand, admits two different interpretations, and it is the context of the utterance that decides. It can be a request for information, in which the speaker has no preconceived idea of what the answer will be. Alternatively, the interpretation can be the same as in Norwegian if a modal particle or adverb is added, as in Inger Holter bossait dans un bar, n’est-ce pas?
Lingua e spazio urbano a Roma nel racconto di Ettore Scola. Il caso di Una giornata particolare (1977)
Authors: Gargiulo Marco , Catolfi Antonio
Published: November 2019

This article aims to focus on two main aspects of Rome urban space vision and representation through Ettore Scola’s filmography: on the one hand, we try to decode the interconnections between languages and cinematic architectural space and, on the other hand, we intend to disclose how Scola meant to create a connection between his personal cinematic narrative and the tangled urban space in the city of Rome.

Our investigation is mainly focused on the so called “urban village” Palazzo Federici, a town within the city, which is the A Special Day and The Story of a Poor Young Man’s main location.

Palazzo Federici is an architectural complex of 400 dwellings designed by architect Mario De Renzi and built between 1931 and 1937; it is an ideal place to describe a hive shape building, with a squared structure inspired to a small fortified town, with a central courtyard and an empty fountain, that can represent the different faces of the suffocating fascist regime. The interrelation between the social and the architectural structures and between the mental and urban space anatomies are evident in these two films.

Palazzo Federici is a protagonist in the story narrated during the visit of Hitler in Rome, the 6th May 1938, the Special Day when Antonietta (Sophia Loren) and Gabriele (Marcello Mastroianni) meet, and it leads the characters as a dark set for the Story of a Poor Young Man where it describes the drama of human solitude and desperation in a labyrinthine urban environment in Rome.
Trayectorias hacia la libertad individual: el uso de la ironía en la novela El héroe discreto de Mario Vargas Llosa.
Authors: Ahnfelt Vigdis
Published: November 2019

The present study examines the spiritual development of the main characters in the novel The Discreet Hero (2013) by Mario Vargas Llosa, and the aim is to show how irony provides the reader with reflections upon the meaning of individual freedom. The hypothesis suggests that the characters, representing different social and cultural groups of today’s Peruvian society, try to free themselves from surrounding threats and thereby obtain what Isaiah Berlin (1971) terms negative or positive freedom.

The analysis focuses on narrative irony, which operates on three levels of the text: firstly, what it linguistically hides by telling something different, secondly, the discrepancy that emerges between narration and what lies underneath and thirdly, the dialectic ideas that impregnate the text and transmit the ambiguity of the work (Tittler 1984). Ethical irony, according to which the characters of narrative are incoherent figures that pursue coherence (Handwerk 1985), is also included.

The study shows that irony problematizes in what ways the characters perceive individual freedom. All of them experience negative freedom, which emerges when authorities fail in their support and protection of the citizens despite political and economic freedom. In order to obtain positive freedom, individual ethical and social responsibility, knowledge of self and cultural refinement are essential. Through irony, it becomes clear that positive freedom depends on a democratic society and individual values.
As práticas restaurativas como meio eficaz de solução dos conflitos escolares envolvendo o bullying
Authors: Santos Mylena Francielli , Moraes da Costa Marli Marlene
Published: November 2019

Diante da proporção que tomou o bullying dentro das escolas foi promulgada em 2015 a Lei nº 13.185 que institui o Programa de Combate à Intimidação Sistemática (Bullying), trazendo em seus artigos entre outros objetivos a procura por não punir o agressor, buscando meios alternativos de responsabilização pelos seus atos. Diante disso, questionou-se no presente artigo a possibilidade de implantação das Práticas Restaurativas como meio de prevenir e trabalhar soluções para casos de bullying dentro das escolas, visto que, primam não pela punição, mas pela reconstrução das relações. Objetivou-se nesta pesquisa analisar a possibilidade de aplicar as Práticas Restaurativas enquanto política pública de conscientização, prevenção e enfrentamento a condutas que sejam intimidadoras aos alunos, com a participação ativa de professores e de toda a comunidade acadêmica nesse processo, realizar uma breve análise sobre o conceito de bullying nas escolas enquanto fenômeno em constante transformação, essencialmente na era da globalização e estudar a Lei nº 13.185/2015 a partir de suas nuances e perspectivas jurídicas e sociais na sociedade brasileira. Utilizou-se para isso o método de abordagem indutivo e como técnicas de pesquisa a bibliográfica e documental. Deste modo, constatou-se que a Justiça Restaurativa através de suas Práticas Restaurativas, é eficaz para trabalhar esta violência de forma mais humana, criativa e sensível, buscando solucionar a violência sistemática dentro das escolas.

Published: November 2019

Muitas gorduras de origem animal possuem aplicações no desenvolvimento de produtos cosméticos, e de acordo com o conhecimento tradicional, a gordura obtida da pele do frango é capaz de melhorar o processo e a durabilidade do alisamento capilar em afrodescendentes. O objetivo desse estudo foi viabilizar o desenvolvimento de produtos capilares auxiliares ao alisamento afrodescendente contendo gordura da pele de frango. A gordura de frango foi submetida ao processo de limpeza e desodorização com intuito de melhorar as suas características sensoriais. Em seguida, analisou-se a sua composição química por cromatografia gasosa acoplada a espectrometria de massas e espectroscopia no infravermelho e determinou-se o seu índice de iodo. Ao final, foram desenvolvidas três formulações cosméticas capilares contendo diferentes concentrações de gordura: creme de tratamento (20%), creme de pentear (10%) e pomada capilar (15%). As formulações foram submetidas aos testes de estabilidade acelerada durante 90 dias. Após os procedimentos de limpeza e desodorização, obteve-se uma gordura mais límpida e inodora. Foi possível identificar a presença predominantemente dos ácidos graxos oleico, palmítico e linoleico, caracterizados por cromatografia gasosa acoplada a espectrometria de massas e espectroscopia no infravermelho. O valor encontrado para o índice de iodo foi de 90,82 I2/100 g. As formulações desenvolvidas se mantiveram estáveis durante o estudo da sua estabilidade, ocorrendo apenas uma pequena alteração de pH em uma das formulações. Diante disso, foi possível desenvolver produtos capilares estáveis contendo a gordura da pele de frango.
Comparison of the Methods of Classical and Synergetic Theories of Control of the Movement Autonomous Underwater Machine
Authors: Kolesnikov A. A. , Yakimenko O. I. , Radionov I. A. , Kaliy D. S.
Published: November 2019

The article deals with the problem of nonlinear synthesis of the laws of motion control of an autonomous underwater vehicle (APA) in the vertical plane. The tasks of the synthesis are the output of the underwater vehicle to a predetermined depth at a given speed. Based on the non-linear mathematical model of the APA, the control laws are synthesized by two different approaches: using the classical automatic control theory method, the proportional-integral-differential controller (PID controller), and using the synergetic control theory, the analytical design method for aggregated regulators (ADAR). Classical methods of the theory of automatic control assume a linear or linearized mathematical description of controlled processes and scalar control, which cannot but affect the adequacy of the mathematical description of processes and the efficiency of the developed algorithms. Such structures are ineffective because they do not allow to obtain the necessary stability margin of the system and are approximate. In addition, the scalar control principle often limits the ability to effectively influence the system, ignoring potential control channels. The vector control principle used in the work allows to more effectively influence the system through various control channels. The assumed laws of synergetic control endow the object in question with properties of asymptotic stability in the entire admissible region of change of state variables.

The results of computer simulation of the APA motion, which confirm the achievement of control goals, are considered.

Authors: Pylypchuk T. , Tesolkina T. , Lukashov D.
Published: November 2019

Leaf litter is an important structurally fucnctional element of forest ecosystem, dynamic processes in which create a connection between
phytocenosis and edaphotope. Accumulation of litter material and its decomposition rate characterize intensity of substance circulation in forest ecosystem. The present article deals with the results researching of the peculiarities of the forming and decomposition of soil litter layer in the hornbeam oak in the conditions of Holosiivskyi National Nature Park (Kyiv) were examined. Its considerable sizes on the north slope of ravine coast system (16,4 t/ha in autumn, 4,3 t/ha in the summer) were determed. Analysis of litter supply at the end of abscission showed a lack of significant differences in different sections of the terrain (12,3–16,4 t/ha). During the winter period, litter volumes are significantly reduced due to intensive mineralization processes under the snow cover. Most intensively, these processes take place in areas of the slope. Fractional composition of the litter did not generally depend on the location of the experimental area by relief elements. A dominating faction in autumn and spring was fall (65–69 % of the total mass). In the summer, a portion of dust (38-46 %) increased. The smallest number of branches was observed in autumn and winter, their scope was between 11-22 % in all research areas. The maximum amount of branches was observed at all areas in the summer. Their volume
was 27-49 %. The scope of seeds and its residues was insignificant and amounted to 1-3 % during the year. The speed of mineralization of cellulose by an application method with the use of filter paper is determined. The rate of decomposition of cellulose in the conditions of the southern and northern ravine slope turned out to be similar to the maximum in March and July-August.

A questão do planejamento curricular se apresenta como um dos elementos centrais quando se reflete a respeito do complexo processo de ensino-aprendizagem escolar, particularmente da Educação Básica. Nessa perspectiva busca-se responder aos questionamentos por que fazer, o que é e como fazer um projeto de currículo para o ensino escolar com princípios da interdisciplinaridade e, em consonância com essa problemática, alcançar os objetivos de expor razões favoráveis à adoção na prática docente desse paradigma pedagógico, de mostrar alguns de seus traços conceituais e de sinalizar caminhos para sua efetivação. Com base em aspectos teóricos e metodológicos de pesquisadores sobre o fenômeno da interdisciplinaridade e sua relação com a organização curricular, empreendeu-se uma pesquisa de cunho bibliográfico, descritivo e analítico. Acredita-se que os pressupostos conceituais, as luzes pedagógicas e as reflexões apresentadas no trabalho possam contribuir para aprofundamento da compreensão do tema pelos atores sociais que pensam e atuam na educação do Brasil. Palavras-chave: Processo de Ensino e Aprendizagem.

Educação Ambiental e Apropriação de Valores: um Diálogo Possível na Educação Infantil
Authors: Bissaco Cristiane Magalhães
Published: November 2019

Partindo do entendimento de que a Educação Ambiental deve ser uma prática intencionalizada e coerente, este trabalho se propõe a realizar uma revisão bibliográfica que articule o campo teórico da Educação Ambiental com o da Educação Infantil, a fim de observar os limites e as possibilidades da prática docente ao tratar da construção ou apropriação de valores. Assim, os seguintes questionamentos norteiam a pesquisa: que práticas docentes podem ser identificadas em relação à apropriação de valores? Elas abarcam a temática ambiental? Em que contextos são pesquisadas? A Educação Infantil é um desses contextos? Para tal discussão foram levantados nove artigos internacionais, que levam o leitor a compreender que as práticas docentes em relação aos valores ensinados são distintas de um artigo para outro: sendo dois deles como prática moral, três como construção, dois como socialização, um como formação de hábitos e um como clarificação. Apenas dois dos artigos não abarcam a temática ambiental. Em relação ao contexto de pesquisa, neste levantamento os artigos estão assim distribuídos: cinco destinados à Infância - Educação Básica, um trata da Educação básica com adolescentes e três destinados ao Ensino Superior. Portanto, concluiu-se que a Educação Infantil é um dos contextos em que a Educação Ambiental tem sido pesquisada, principalmente, no que se refere à apropriação de valores pertinentes à temática ambiental. Palavras-chave: Educação Moral. Meio Ambiente. Infância. AbstractBased on the understanding that Environmental Education should be an intentional and coherent practice, this paper proposes to perform a literature review that articulates the theoretical field of Environmental Education with that of Early Childhood Education, in order to observe the limits and possibilities of teaching practice, when dealing with the value construction or appropriation. Thus, the following questions guide the research: What  teaching practices can be identified in relation to the values appropriation ? Do they cover the environmental theme? In what contexts are they researched? Is early childhood education one of these contexts? For this discussion nine international articles were raised, which lead the reader to understand that teaching practices in relation to the values taught are distinct from one article to another: two of them as moral practice, three as construction, two as socialization, one as habits formation and one as clarification. Only two of the articles do not cover the environmental theme. Regarding the research context, in this survey the articles are directed to: five for Childhood - Basic Education, one for Basic Education with adolescents and three for Higher Education. Therefore, it was concluded that early childhood education is one of the contexts in which environmental education has been researched, especially regarding the appropriation of values relevant to the environmental theme. Keywords: Moral Education.
