Low-Copy Nuclear Genes Reveal New Evidence of Incongruence in Relationships Within Malvaceae s. l.
Authors: Hernández-Gutiérrez Rebeca , Mendoza Carolina Granados , Magallón Susana
Published: January 2022

Abstract—The family Malvaceae s. l. is a clade that comprises nine subfamilies. Phylogenetic relationships among them are not completely resolved and are inconsistent among studies, probably due to low phylogenetic informativeness of conventional molecular markers. In the present study, we provide new phylogenetic information for Malvaceae s. l. derived from newly-designed group-specific nuclear markers. By mining transcriptome data from the One Thousand Plants Project (1KP) and publicly available genome information from cotton, cacao, andArabidopsis,we designed a set of molecular markers of potentially single- or low-copy nuclear genes for Malvaceae s. l. Phylogenetic potential of these new loci was compared to previously applied conventional markers (i.e. plastidtrnK-matKregion andrbcLgene and the nrDNA ITS region) using the phylogenetic informativeness method. The results show that, when the mined nuclear regions are used in combination, it is possible to resolve relationships at different taxonomic levels within the phylogeny. However, incongruence among nuclear loci is frequent in the group, explaining the prevalence of unresolved phylogenetic relationships.
Castela senticosa (Simaroubaceae: Sapindales), a New Species from the Caribbean Clade Endemic to Seasonally Dry Tropical Forest on Hispaniola
Authors: Majure Lucas C. , Pham Kasey , Clase Teodoro
Published: January 2022

Abstract— Recent fieldwork in the Sierra Martín García in southwestern Dominican Republic has yielded a new species of the American clade Castela (Simaroubaceae), Castela senticosa sp. nov., from seasonally dry tropical forest. This
species has been collected from two separate localities, including Môle St. Nicolas in northwestern Haiti in 1929, but until now fertile material with both flowers and fruit was unknown. We provide a photographic plate and illustration, place it phylogenetically using plastome data,
and compare it morphologically with close relatives. This increases the number of known species of Castela on Hispaniola from one to two, both of which are endemic but from different clades, and yields another species for the Greater Antilles, a known biodiversity hotspot and clear
center of diversification for this group of arid-adapted, thorny shrubs. This work emphasizes that seasonally dry, tropical forests, although often understudied, house as yet undiscovered biodiversity and deserve far more comprehensive studies.
Phylogeny and Biogeography of Acaena (Rosaceae) and its Relatives: Evidence of Multiple Long-Distance Dispersal Events Across the Globe
Authors: Jauregui-Lazo Javier , Potter Daniel
Published: January 2022

Abstract— Acaena (Rosaceae) is the most complex and ecologically variable genus in Sanguisorbinae. Although it has been the subject of several taxonomic treatments, the largest phylogenetic analysis to date only sampled a small fraction of the total global diversity
(five to seven out of 45 to 50 species). This study included most of the species to elucidate the phylogenetic relationships of Acaena and biogeographic patterns in Sanguisorbinae. Phylogenetic analyses of non-coding nuclear (ITS region) and chloroplast (trnL-F) DNA sequence
markers using maximum likelihood and Bayesian analyses suggested that Acaena is a paraphyletic group with species of Margyricarpus and Tetraglochin nested within it. We identified strong support for eight subclades that are geographically or taxonomically structured. Nevertheless,
the species-level relationships within subclades are still uncertain, which may be due to rapid diversification and lack of informative characters in the markers used. Sanguisorbinae, a primarily Southern Hemisphere clade, exhibits a classic Gondwana disjunct distribution. This current distribution
is explained primarily by eight long-distance dispersal events. Our results suggested that Sanguisorbinae split into Cliffortia and Acaena around 13.6 mya. While Cliffortia diversified in southern South Africa, Acaena experienced several migration events in the
Southern Hemisphere. Our estimation of the ancestral range suggested that Acaena likely originated in South Africa, followed by migration and subsequent diversification into southern South America. From there, the genus migrated to New Zealand, throughout the Andes, and to tropical
areas in Central America, reaching as far north as California. Chile and New Zealand are the main sources of propagules for dispersal as well as the greatest diversity for the genus. The evolutionary relationships of species in Acaena combine a history of rapid diversifications, long-distance
dispersals, and genetic variation within some taxa. Further research should be undertaken to clarify the infraspecific classification of A. magellanica.
Morphometric Analysis as a Tool to Resolve a Taxonomic Complex in Myrcia sect. Calyptranthes (Myrtaceae, Myrteae)
Authors: Burton George P. , Campbell Keron C. St. E. , Lucas Eve J.
Published: January 2022

Abstract— Specimens attributed to Myrcia chytraculia and associated species form a complex within M. sect. Calyptranthes, occurring sympatrically throughout the Caribbean and Central America and sharing a continuously variable suite of morphometric
traits. To ascertain whether species within this complex should be treated as separate or conspecific taxa, seven morphometric traits and a further two discrete characters are analysed using univariate and multivariate statistics. Leaf size and shape are found to be indicative of subspecies,
and significant mean differences of traits can be found between groups, though they overlap throughout the range of the M. chytraculia complex. As a result of these findings, updated taxonomy for this group is proposed, creating the new combinations Myrcia chytraculia var.
americana, Myrcia chytraculia var. pauciflora, and M. chytraculia var. zuzygium, as well as seven new synonyms. A distribution map and a key to the new varieties are also included.
Are Palmer’s Elm-Leaf Goldenrod and the Smooth Elm-Leaf Goldenrod Real? The Angiosperms353 Kit Provides Within-Species Signal in Solidago ulmifolia s. l.
Authors: Beck James B. , Markley Morgan L. , Zielke Mackenzie G. , Thomas Justin R. , Hale Haley J. , Williams Lindsay D. , Johnson Matthew G.
Published: January 2022

Abstract— The genus Solidago represents a taxonomically challenging group due to its sheer number of species, putative hybridization, polyploidy, and shallow genetic divergence among species. Here we use a dataset obtained exclusively from herbarium specimens
to evaluate the status of Solidago ulmifolia var. palmeri, a morphologically subtle taxon potentially confined to Alabama, Arkansas, Mississippi, and Missouri. A multivariate analysis of both discrete and continuous morphological data revealed no clear distinction between S.
ulmifolia var. palmeri and Solidago ulmifolia var. ulmifolia. Solidago ulmifolia var. palmeri’s status was also assessed with a phylogenomic and SNP clustering analysis of data generated with the “Angiosperms353” probe kit. Neither analysis
supported Solidago ulmifolia var. palmeri as a distinct taxon, and we suggest that this name should be discarded. The status of Solidago delicatula (formerly known as Solidago ulmifolia var. microphylla) was also assessed. Both morphological and phylogenetic
analyses supported the species status of S. delicatula and we suggest maintaining this species at its current rank. These results highlight the utility of the Angiosperms353 probe kit, both with herbarium tissue and at lower taxonomic levels. Indeed, this is the first study to utilize
this kit to identify genetic groups within a species.

Authors: Cota Matheus Martins Teixeira , Rando Juliana Gastaldello , Snak Cristiane , de Queiroz Luciano Paganucci
Published: January 2022

Abstract— Plants from Brazilian campos rupestres usually present morphological strategies that allow them to survive in extreme environments. However, in Chamaecrista (Leguminosae, Caesalpinioideae), one of the most diverse genera in the campos rupestres, needle-like
leaflets are rare. Reviewing the species that present such leaf morphology, we describe Chamaecrista acicularis, a new species from the Canastra Range, in the southwestern region of the state of Minas Gerais, Brazil. Phylogenetic analyses revealed that C. acicularis is
not closely related to other quite similar needle-like leafleted species and that this trait evolved convergently. We also present comments on the phylogenetic relationships of needle-like leafleted species as well as the evolution of the leaflet amplitude, and a detailed description of C.
acicularis alongside illustrations, photos, geographical distribution, a key to the needle-like leafleted species and taxonomic notes on similar species. Additionally, we expand the description of Chamaecrista strictifolia and present an informal conservation status for all needle-like
leafleted species.

Published: January 2022

This paper reports the results from field tests on a 1/15th scaled fish anchor. The tests were conducted at three locations in the Swan River, Perth, Australia. Two series of tests were performed from the Burswood and Maylands jetties with water depths between 1·1 and 1·9 m. The final series of tests were undertaken in deeper (2·6 m) waters from a barge. The riverbed at the Burswood jetty and barge test location consisted of clay, and that at the Maylands jetty comprised sandy silt. The tip embedment depths of the scaled fish anchor, with dry weight of 0·304 kN and impact velocity of 5·89–9·55 m/s, in soft clay were 1·17–2·40 times the anchor length. For similar impact velocities, the embedment depths in sandy silt were 30–60% shallower. By comparing the field test data in clay, the fish anchor achieved normalised embedment depths similar to those of the torpedo and OMNI-Max anchors under half or less impact velocity. Importantly, the field tests confirmed the diving behaviour of the fish anchor under loading with mudline inclination of 20° and 25°, with the second peak dictated by the capacity. The ultimate capacity was 5–7 times that of the anchor submerged weight in water.

Published: January 2022

The aim of this study was to analyze the association between institutional variables and the performance of Accounting and Administration students. The microdata of Enade 2018 were used, obtaining 152,491 valid observations. Performance was measured in three ways: final performance, performance in the general training test and performance in the specific component test. In addition, the following institutional variables were considered: academic organization, region, modality and shift. The data were examined using zero adjusted Box Cox Cole Green (BCCG) regression models. The results indicated the institutional variables were relevant to explain the performance. Specifically, it was staked students enrolled in federal centers of technological education had superior performance than the other forms of academic organization. Another relevant point was the students in the North region performed worse than other regions in general. However, they outdid the students from Central-East region in the issues of general training. Regarding the teaching modality, it was found that students of face-to-face teaching presented higher performance than the distance learning students (DL). And the full-time students had better performances overall. As implications, it is pointed out that institutions offering Accounting and Administration courses in the Northern region may want to improve the quality of education, as well as those of the Centre-Western shall want to do so in relation to general training education. Similarly, the teaching on the DL modality can be improved and the offer of full-time courses can be thought of and potentially implemented.

Published: January 2022

In the field of medical robotics, many studies have called for the integration of end-users in the innovation process. The objective is to identify the factors that facilitate (or not) the use of the designed robots and thus try to guarantee their diffusion in the care services. This recommendation was followed in the ROBO-K project. The ROBO-K project proposes the design and development of a mobile, interactive robot dedicated to gait rehabilitation. This project was initiated by BA Healthcare, a medical robotics company. The design of a robot was accompanied to achieve the targeted therapeutic objectives by taking into account the requirements related to the needs of the patients and the practitioners; the care activity and the institutions involved. A follow-up by the social acceptability of the technology led to focus the innovation process on a co-construction activity involving all stakeholders. This co-construction activity was decisive, as it guided the definition of functional expectations and the technical specifications of the prototype developed. It was completed by a test phase of the prototype (in a care situation for 5 months). The results show the relevance to involve all the stakeholders in all the design and development phases of the robotic device. However, they underline the difficulties or limits linked to this type of approach in terms of innovation.

How Conscious Is a Compulsive Buyer? A Case Study
Authors: DOĞAN Semra
Published: January 2022

Compulsive buying is often studied in the field of psychiatry and marketing as a behavioral disorder. While individuals who exhibit compulsive (excessive) buying behavior hold common features in terms of some characteristics, there is limited information about the extent to which consciousness is included in the purchase decision, the awareness of the individual and the extent to which s/he can control himself / herself in purchase behavior. In this case study, I made in-depth investigations about the excessive purchase behavior of an individual whom I identified as a compulsive buyer according to a compulsive buying screener. I have developed the themes of excessive (compulsive) buying motivations and conditions, conscious consumption, buying process and buying consciousness and identified sub-themes. The findings I have obtained show that the compulsive buyer, who is a female consumer, exhibits similar characteristics with the relevant literature by excessive purchase behaviour especially in clothing and similar products. On the other hand, she also takes precautions by creating a consciousness to prevent excessive consumption during shopping process, which she sees as a leisure time activity. In other words, while making purchases with the motivation of public self-consciousness, she tries to prevent this by showing private self-consciousness. In the conclusion I related them to the relevant literature and proposed recommendations.

Authors: DURA Yahya Can , YALÇINTAŞ Selin
Published: January 2022

The study, which deals with the changes created by the globalization indicators on the public sector, is shaped on the basis of the compensation and efficiency hypothesis. In this context, it has been investigated how the government size is affected due to the fact that the effects of globalization are felt more with the shift of transition countries from centrally planned economy to free market economy. According to panel OLS and causality test results, increases in economic freedom index, one of the globalization indicators, decrease public consumption expenditure. In this context, the efficiency hypothesis is valid for Albania, Bulgaria, Czechia, Estonia, Romania and Slovakia for the period 1995-2019.

Design Simulation of Improved Power Quality Conditioner System for Enhancement of Power Quality
Authors: Yadav Sunny , Ali Sabir , Arora Amit
Published: January 2022

The increased usage of power-sensitive electronic devices has prompted interest in power conditioning solutions, which is no surprise. As a result, some type of compensation must be supplied if power output remains below the standards' prescribed limitations. The UPQC (Unified Power Quality Controller) is one of numerous AC Transmission System families that can control voltage, impedance, and phase angle among other factors (FACTS). This study focuses on modern UPFC systems that have increased power quality efficiency to help utilities reduce voltage concerns. One of the FACTS controls for lowering stress sales effects is a unified power quality conditioner (UPQC). The quadrature voltage is specified using the UPQC series compensator. As a result, the compensator series never utilizes active power in a continuous scenario. As mentioned in the approach, a low power rating compensator injects voltage to remedy the system's power quality problem. The voltage is decreased and the power factor is raised when the fluid logic controller is used in conjunction with traditional UPQC. Furthermore, the load factor has been improved. The circuit is then imitated in MATLAB / SIMULINK using a fluctuating logo controller.

Published: January 2022

This paper designs, analyzes and optimizes the electric vehicle wireless charging system and its control method. Compared with the traditional plug-in conduction charging, wireless charging is more convenient, safe, reliable and has better environmental adaptability. Inductive power transmission technology (IPT) is the main technology for wireless charging of electric vehicles and plug-in hybrid vehicles. Based on the fundamental approximation method, the critical self inductance of the primary or secondary coil is derived in this paper. This critical value reflects the power transmission capacity and control performance of the two chargers when they are interoperable. Compared with the non integrated structure, the magnetically integrated LCC compensated wireless charging system can transmit the same power with smaller compensation inductance. Based on the voltage dependent dynamic state space model, four working modes of magnetically integrated LCC compensated wireless charging system are studied in this paper. Simulation and experimental results show that the voltage dependent equivalent circuit model can be effectively applied to the basic characteristic analysis of wireless charging system. The voltage dependent dynamic state space model is more accurate and realistic. In addition to reflecting the basic characteristics of the wireless charging system, it can also reflect the working mode of the wireless charging system.

Starting from the emergence of 1st Generation network (1G), wireless mobile communications have been undergoing an evolution - from 2nd Generation (2G), 3rd Generation (3G), 4th Generation (4G) networks to 5th Generation network (5G) at present. The fifth era is only a continuation of the ongoing evolution as it is still in the research phase and is also the basis for further development of industries and the society in general. The paper presents and compares the fourth and fifth generation of wireless mobile communications, focusing on the differences and progress in terms of data transmission rate, capacity, architecture, technology and applied multiple-technique approaches and services provided.

We analyzed the performance of the artificial neural network with the backpropagation method in predicting crude oil prices in this paper, including the case of crude oil price predictions. The training results obtained that the MSE value was 0.00099762 with 135 Epoch, in the network testing the MSE value was 0.093336. Meanwhile, the predicted value is determined by the target value with a contribution of 99% with a significant effect. Thus the accuracy level is determined by the target value and the predicted value. The accuracy of the system is obtained for 83,6%.

Neste estudo, analisamos os padrões discursivos em aulas de ciências no Ensino Fundamental usando como estratégia de ensino a Roda de Conversa, na abordagem do tema “Evolução”, tendo como eixo orientador os aspectos sociais, tecnológicos e científicos da Vida de Darwin, que permitem estabelecer estratégias focadas no diálogo, no questionamento e na argumentação. Orientados pelos estudos etnográficos, acompanhamos o desenvolvimento de três Rodas de Conversa, ao longo de três semanas, com duas turmas de estudantes do 7º ano do Ensino Fundamental. Exploramos interações discursivas nesse evento, caracterizando as práticas discursivas, os movimentos e práticas epistêmicas que ocorriam no decorrer das Rodas de Conversa. Os resultados indicaram o modo pelo qual os processos de aprendizagem se constituíram mediante articulações entre tais movimentos, bem como as relações entre eles. Verificamos que nos episódios em que há predominância de abordagem comunicativa dialógica, as práticas epistêmicas que se destacam estão na instância da comunicação e avaliação do conhecimento, e os movimentos epistêmicos desenvolvidos pela professora são de reelaboração, instrução e compreensão. Por outro lado, quando buscamos as relações entre os movimentos e as práticas epistêmicas, verificamos que estas últimas, desenvolvidas pelos estudantes, têm forte relação com as ações da professora.
Problemas mistos em livros didáticos: uma classificação com base na teoria dos campos conceituais
Authors: Rodrigues Carla Larissa Broza Halum , Rezende Veridiana
Published: January 2022

A presente investigação tem como objetivo analisar problemas mistos propostos em uma coleção de livros didáticos de matemática do 1º ao 5º ano do Ensino Fundamental, na perspectiva da Teoria dos Campos Conceituais. Consideramos como problemas mistos aqueles que envolvem ao menos uma vez uma relação aditiva e uma relação multiplicativa. Para a análise destes problemas consideramos os pressupostos estabelecidos por Gérard Vergnaud  para o Campo Conceitual das Estruturas Aditivas e o Campo Conceitual das Estruturas Multiplicativas, além das possibilidades de classes de problemas mistos divulgadas por Miranda (2019). Na coleção de livros didáticos analisada foram identificados quarenta e seis (46) problemas mistos, que foram classificados em seis (6) subclasses. As análises mostram a predominância da classe proporção simples e composição de medidas, que somou vinte e cinco (25) problemas mistos. Já a classe produto de medidas e composição de medidas foi identificada uma única vez na obra. Inferimos, com base na Teoria dos Campos Conceituais e nos resultados dessa investigação, que a variedade de diferentes situações de problemas mistos favorece/possibilita que estudantes mobilizem e se apropriem de diferentes raciocínios aditivo e multiplicativo ao longo de sua vivência escolar.
Cultura matemática de um profissional: concepção semântica na teoria: a Matemática no contexto das Ciências
Authors: Bianchini Barbara Lutaif , Lima Gabriel Loureiro de , Gomes Eloiza
Published: January 2022

O objetivo deste artigo é apresentar o resultado da investigação que possibilitou a elaboração de uma concepção semântica (significado e âmbito de aplicação) do termo cultura matemática de um profissional que fosse aderente aos paradigmas e ao pressuposto filosófico educacional da Teoria A Matemática no Contexto das Ciências, desenvolvida pela pesquisadora mexicana Patricia Camarena Gallardo. Do ponto de vista metodológico, esta investigação qualitativa, de caráter bibliográfico, realizou-se a partir do método das reduções comparativas em fase um, que se fundamenta em uma proposta de análise comparativa. Estabelecida a concepção semântica para o mencionado termo, identificou-se cinco dimensões que constituem a cultura matemática de um profissional: cognitiva, atitudinal, axiológica, de aplicação e reflexiva. Além disso, explicitou-se que o componente nuclear da cultura matemática de um profissional são as competências matemáticas para a profissão, que por se constituírem de uma articulação de conhecimentos, habilidades, atitudes e valores, estão vinculadas simultaneamente às cinco dimensões citadas. Por fim, estabeleceu-se três níveis para o desenvolvimento da cultura matemática de um profissional: baixo, médio e alto.
¿Promueven los libros de texto la indagación científica?
Authors: Aragüés Ana
Published: January 2022

Este trabalho centra-se no estudo de atividades propostas em livros didáticos de ciências de 1º, 3º e 4º ano do Ensino Fundamental, correspondendo a três editoras espanholas. Especificamente, é analisado o grau de promoção de estratégias de investigação científica propostas aos alunos. A análise se concentra na categorização da demanda para cada uma das atividades que aparecem na seleção dos livros, de acordo com um sistema de estratégias científicas. Os resultados mostram uma escassa presença de atividades que promovam o conjunto de estratégias, evidenciando uma grande maioria de atividades de preparação para a escrita, descrição ou classificação oral, identificação e união. Consequentemente, há necessidade de mudanças nos livros didáticos condizentes com uma aprendizagem abrangente dos processos que caracterizam a atividade científica.
Um panorama do elemento Tecnologia na Educação CTS e o ensino de Ciências
Authors: Lima Dioginys Cesar , Dantas Josivânia Marisa
Published: January 2022

O campo de estudos Ciência, Tecnologia e Sociedade (CTS) vem sinalizando, nos últimos anos, obstáculos para implementar o acrônimo CTS como um todo no ensino de Ciências, principalmente o segundo elemento, Tecnologia (T). A fim de contribuir com a discussão acerca das relações que envolvem essa tríade, realizamos uma ampla revisão bibliográfica em bases de dados e periódicos da área de ensino, buscando produções que abordaram a Tecnologia na Educação CTS e o ensino de Ciências entre os anos de 2010-2020. Para tal, foi necessário analisar qual sentido de tecnologia prevalece nos resultados dessas produções. Foram selecionados 39 artigos, considerando os critérios de inclusão. Para o tratamento analítico desse corpus, utilizamos elementos da análise de conteúdo de Bardin (1977). As categorias emergentes a posteriori foram: Natureza do Trabalho; Concepção de Tecnologia; e Tecnologia na Abordagem CTS. A maioria dos trabalhos analisados traz concepções restritas/simplistas de tecnologia em seus resultados, seja de professores em exercício, professores em formação ou estudantes da educação básica. Assim, inferimos a necessidade de uma maior difusão e ascensão do sentido atribuído à tecnologia, considerando sua amplitude de maneira crítica. Abordagens que partem desse entendimento no Ensino de Ciências estabelecem de fato uma efetiva educação científico-tecnológica.

Este artigo é resultado da revisão bibliográfica de uma tese e tem como objetivo apresentar um diálogo por meio da abordagem CTSA (Ciência, Tecnologia, Sociedade e Ambiente) com a perspectiva do estudo implicado, que contemple a pesquisa e o ensino de ciências no contexto amazônico. Para isso, retoma a origem do movimento Ciência, Tecnologia e Sociedade, comenta a natureza da implicação e sua relação com a abordagem CTSA, vinculados a três elementos: objetivos; interações entre ciência, tecnologia, sociedade e ambiente; e estratégias de ensino. Além disso, tece uma discussão com os princípios da abordagem como a participação ativa, a dialogicidade e a problematização, associadas à ideia de transformação da realidade. Por fim, defende a perspectiva do estudo implicado para a pesquisa e o ensino de ciências por meio da abordagem CTSA para a Amazônia, considerando a diversidade que a compõe.
O irmão/pai de uma desaparecida política
Authors: Frederico Graziele
Published: January 2022

Os arquivos reunidos pela Comissão Nacional da Verdade expõe a busca labiríntica de Majer e Bernardo Kucinski por Ana Rosa e Wilson, desde 22 de abril de 1974. Como podemos ler no material recolhido, os familiares buscaram notícias e apelaram sem sucesso nos últimos quarenta anos para autoridades estrangeiras e nacionais. A postura do regime foi sempre negar a prisão e de alguma maneira vincular os desaparecidos, como subversivos. Também Bernardo Kucinski foi fichado por suas posições e pelo “incômodo” que vinha causando à imagem do governo ditatorial. Posteriormente, já na redemocratização, a Marinha divulgou um relatório acusando Ana Rosa de ter sido vítima do serviço secreto estadunidense em resposta aos trabalhos que ela supostamente realizaria para o governo israelense. Mais uma mentira, que como escreveu na época Bernardo Kucinski, visava mais uma vez impedir que se soubesse a verdade e negavam a memória de que ela lutara contra a ditadura militar e por isso foi detida, tortura, assassinada e desaparecida.
