Published: August 2021

Este artigo é motivado pelo seguinte questionamento: como tornar as mídias de línguas ameaçadas e suas respectivas anotações úteis e acessíveis (em termos de manuseio e compreensão) à etnia e ao público geral? O trabalho se insere no âmbito da documentação linguística (GIPPERT; HIMMELMANN; MOSEL, 2006) – entendida como compilação e preservação de dados linguísticos primários – e apresenta uma metodologia preliminar de disponibilização de anotações elaboradas nos softwares ELAN e FLEx e suas mídias correspondentes. Trata-se de um procedimento com manuseio e visualização relativamente simples através do LingView (PRIDE; TOMLIN; ANDERBOIS, 2020), uma interface na internet prática e amigável para visualização simultânea de dados linguísticos primários e suas anotações. A proposta de metodologia é aplicada a dados primários da língua Wayoro (código ISO wyr; Glottocode wayo1238) (família Tupi, subfamília Tupari) publicados em artigo (NOGUEIRA; MACURAP; WAJURU, 2019) e na tese de doutorado de Nogueira (2019), como exemplo, mas pretende poder ser replicada aos dados de qualquer língua.

Published: August 2021

Objectives:

The Milan system for reporting salivary gland cytopathology (MSRSGC) classification has been proposed to improve reproducibility in the management of salivary gland lesions. Fine-needle aspiration cytology (FNAC) is a widely accepted, well-tolerated, cost-effective, minimally invasive diagnostic method for pre-operative evaluation of salivary gland lesion that aids management decisions. The present study aims to reclassify the salivary gland FNAC aspirates by applying MSRSGC and calculating the risk of neoplasm and malignancy for each diagnostic category.

Material and Methods:

The present study is a retrospective observational study done for 54 months. A total of 168 cases of salivary gland FNA, 54 cases were excised in our institute for histopathology. Retrospective reviews were performed, and the FNAC cases were reclassified according to the Milan system, and the results of FNAC and final histology were correlated, wherever available. Furthermore, the risk of malignancy was calculated for all the diagnostic categories. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy (DA) of FNAC were determined.

Results:

In the present study, the age of patients ranged from 3 to 86 years, with a mean age of 39 years. Among all the patients, 61.3% were male, and 38.6% were female. However, only 54 salivary gland FNA samples for which histopathology was available were categorized into six categories. Among them, category IV (neoplastic) had a maximum number of cases of 66.6%. The rate of malignancy was calculated for all diagnostic categories as follows: (1) Non-diagnostic: 0.0%, (2) non-neoplastic 0.0%, (3) atypia of undermined significance 100%, (4a) benign 5.5%, (4b) uncertain malignant potential 33.33%, (5) suspicious for malignancy 00%, and (6) malignancy 80%. The sensitivity, specificity, PPV, NPV, and DA for differentiating between benign and malignant neoplasm were 36.3%, 94.4%, 66.6%, 82.9%, and 80%. Two false-positive and seven false-negative neoplastic cases were noted.

Conclusion:

FNAC is a reliable, minimally invasive diagnostic method with high DA for diagnosing salivary gland lesions. Most salivary gland lesions can be accurately diagnosed on FNAC with adequate sampling and cytopathologists experience.

Resumen: Este texto analiza las ejecuciones extrajudiciales acontecidas en Colombia entre los años de 2002 y 2010, durante el gobierno del expresidente Álvaro Uribe Vélez, caracterizadas por su crueldad: primero, se intentaron justificar argumentando que los ejecutados eran “enemigos” del Estado (guerrilleros, paramilitares, narcotraficantes, etc.), “dados de baja” en operativos defensivos de la fuerza pública, cuando realmente se trató de combates simulados con víctimas arbitrariamente privadas de su libertad y en condiciones de indefensión; segundo, los miles de casos fueron consecuencia de una política que valoró a sus agentes por el “número de bajas” de sus “enemigos”, estableciendo recompensas, premios y reconocimientos por ese motivo. Esta violencia institucional, sirvió a propósitos abyectos del poder político: hizo “populismo punitivo” con las cifras de “bajas” para la reelección presidencial; encubrió las falencias de las negociaciones con el paramilitarismo, así como la connivencia del Estado con este actor; incrementó la sensación de “seguridad ciudadana”, criminalizando la pobreza. Finalmente, desplegó varios dispositivos para garantizar la impunidad de estos crímenes, a través del fuero penal militar y, luego, tratando de reproducir los privilegios de esta jurisdicción, en el campo de Justicia Especial para la Paz.

In this research, NiAl-LDH was synthesized using the coprecipitation method and modified with biochar and graphite to produce NiAl-biochar and NiAl-graphite composite materials. The adsorbent that has been synthesized is used for the application of adsorption of Fe(II) ions in aqueous solution. The resulting material was characterized by XRD (X-ray Diffraction) analysis, spectrophotometer FT-IR, BET analysis for determine the specific surface area and TG-DTA analysis. XRD diffractogram showed that the NiAl-Biochar and NiAl-graphite composite material had the diffraction pattern characteristic of the precursor. LDH that has been modified will have a larger surface area than the precursor. The surface area of NiAl-biochar reaches 438.942 m2/g and the surface area of NiAl-graphitereaches 21.595 m2/g. This composite material supports adsorbents with a large adsorption capacity to adsorb metals. Adsorption of Fe (II) using NiAl-Biochar and NiAl-graphite was stable for five regeneration cycles (<75.30%). The Fe(II) ion adsorption process tends to follow the Langmuir isotherm model which has a maximum capacity value (Qmax) of NiAl-Biochar composite material reaching 20 times with a value of 243.902 mg/g and the NiAl-graphite composite reaching 72.464 mg/g, so that the carbon-based composite material is considered effective. adsorbent to remove Fe(II) ion and can increase the stability of the structure for adsorption regeneration. The results of the analysis of thermodynamic parameters showed that the adsorption process was endothermic, tookplace spontaneously and the solid-liquid phase interface increased according to the increasing degree of disorder.

У роботі проведено дослідження особливостей заселення інвазійного виду молей-строкаток (Grаcillаriidаe Stаinton, 1854) білоакацієвої молі- строкатки (Pаrectopа robiniellа Clemens, 1863) різних паркових екосистем м. Дніпро. Оцінку масштабів інвазії та активності заселення різних екосистем мінером-інвайдером було здійснено за кількістю візуально зареєстрованих мін на листках кормової рослини робінії псевдоакації (Robinia pseudoacacia Linnaeus, 1753). Дослідженнями було охоплено всі основні за розмірами паркові екосистеми м. Дніпро, де висаджено дерева кормової рослини. Польові спостереження проведено протягом трьох вегетаційних сезонів (2018–2020 рр.). Морфологічні дослідження мін P. robiniellа проводили на стадії їх максимального розвитку, що відповідало останньому віку гусені. Для цього використано такі параметри: довжину міни (L) за центральною жилкою, максимальну ширину міни (W), площу міни (S), площу листкової пластинки (Sl). Розраховували відношення довжини до ширини міни (L/W) та відношення площі міни до площі листкової поверхні (S/Sl). З’ясувалось, що найбільша кількість мін реєструвалась у більш чистих зонах м. Дніпро, що розташовувались на високих відмітках рельєфу, – Ботанічному саду ДНУ та парку імені Т.Г. Шевченка, а також у природному заповіднику Дніпровсько- Орільський. Найменша кількість мін реєструвалась ближче до центру міста, у парку Сагайдак та парку імені Лазаря Глоби. Морфологічні дослідження мін дозволили встановити, що коефіцієнт варіації довжини міни дорівнює 0,4, ширини – 0,6, а площі – 0,8. Відношення довжини до ширини менш варіативне, ніж відношення площі міни до площі листкової поверхні. Це, з одного боку, пов’язано з більш стабільною загальною формою міни, з іншого – досить мінливою площею міни, що, вірогідно, залежить від різних факторів міського середовища.
Investigating a real-options approach to modelling public policy investments, and implications for public administration
Authors:   , Butler Callum
Published: August 2021

This thesis investigates the application of real-options modelling to policy investment coordination problems across government departments, with the aim of informing high-level institutional and system design choices in public administration. This analysis is motivated by recent and ongoing reforms to the legislative framework underpinning New Zealand's public service which, unlike the last major public administration reforms of the 1980s, are not expressly driven by or obviously supported by economic theory. We find that a simple real-options framework allows for a compelling illustration of the coordination problems that the current reforms are in part aiming to solve, and supports analysis of the types of mechanism that might be employed to address them. Such mechanisms include the promotion of structural integration, the broadening or alignment of departmental policy objectives, a relaxation of public finance restrictions, and joint decision-making over policy investments.

Emotional Expression and Artistic Reconstruction in Musical Performance
Authors: Yue Li
Published: August 2021

The emotional expression brought by music is the self-realization and artistic reconstruction of the art of music in performance. From the perspective of the development of musical performance, artistic reconstruction is an important means of expression which does not only explores the emotional connotation of music but also endows music with stronger vitality through the performers’ understanding and imagination, presenting them to the audience in a more three-dimensional way and stirring up deep resonance. Performers can also gradually develop their own style of performance. How to better integrate the interaction between the two is an important proposition in exploring musical performance. This paper focuses on the relationship between emotional expression and artistic reconstruction in addition to elaborating the important role of the two in musical performance to provide a useful reference for music creators and performers.

Authors: Mutende Rose Atieno , Imonje Rosemary K , Akala Winston
Published: July 2021

The teaching and learning of science subjects at secondary schools in Sub-Saharan Africa is currently dominated by application of the lecture method in delivering learning material. In the Lecture Method, the teacher discusses and shows the learning material. Studies showed that the lecture method can be made interactive, and, hence, more effective if teachers appropriately integrate constructivist ideas in the method. Therefore, this study aims to examine the BEd (Science) students’ integration of constructivist’s learner-oriented instructional practices in the lecture method during teaching practice (TP). Data were collected from 107 BEd(Science) students, their Head of Subjects in the TP schools and the university supervisors at the onset and towards the end of a 14-week TP. The instruments used to collect data were questionnaires and interview schedules. The data were analysed descriptively and inferentially. Descriptive statistics focused on frequencies, percentages, means and standard deviation which summarised the variables in terms of demonstration of instructional practices, supervision and assessment practices. Findings revealed that the BEd(Science) students faced difficulties in their attempt to integrate constructivist ideas in the lecture method. T-test showed a positive effect of teaching practice on the integration of constructivists’ ideas in the lecture method. The study provides several recommendations based on the findings.

Published: July 2021

Pedagogical strategies for the implementation of the social content of higher education should be exercised through the application of the bottom-up approach. The bottom-up approach is aimed at ensuring proper development of the student’s personality. This approach is based on the subject-specific (academic achievements) and generic (leadership, management skills and focus on personal and professional development) competencies. The purpose of this study was to investigate the range of tools as well as the effectiveness of the bottom-up approach to the implementation of the social component of higher education through perspective development and the emphasis on students’ leadership and management skills. The study is of an empirical nature and the research component is based on the formative experimental methodology. Fifteen students of the Faculty of Primary Education participated in the experimental part of the study. They were involved in the specific bottom-up approach to educational environment organization and were evaluated accordingly by a jury. The two-year implementation period of the bottom-up approach to the implementation of the social content of higher education took place through customized projects of personal and professional development. The average socialization readiness level within the group was 78.2 (out of 100 max.), with 13.3% of students showing an average socialization readiness level, and 86.7% of students achieving a good level. The results confirmed the effectiveness of the principal notions of the study. The task of adapting the content of higher education in order to achieve a positive momentum of students’ socialization readiness was successfully completed.

La caracterización y evaluación de recursos fitogenéticos a partir de su contenido de ácidos grasos y compuestos orgánicos volátiles (COV) permiten determinar su utilidad potencial. Se han realizado pocos estudios recientes relacionados con los COV encontrados en el aguacate, los cuales pueden variar dependiendo del lugar de origen, genética y fenotipos. El objetivo del presente trabajo fue presentar el estado del arte de la fitoquímica del aguacate criollo comparado con variedades comerciales. Se encontró que los COV le confieren un perfil de aroma que identifica a diversas variedades y que los ácidos grasos son responsables de la síntesis de algunos COV. En la hoja de aguacate criollo se identificaron 26 COV, siendo 8 monoterpenoides, 7 sesquiterpenos, 6 fenilprondes, 1 acetato y 4 alcanos; estos COV no se han encontrado en las variedades comerciales. Por otro lado, la variedad Drymifolia se caracteriza por su contenido fenólico, diversos ácidos grasos y acetogeninas. Dichos componentes químicos también se han asociado con diversos beneficios a la salud, como actividad anticancerígena en colon, próstata y células K562, actividad antiinflamatoria y antioxidante. Ello ha propiciado el interés de fomentar su uso como ingrediente, aditivo o fitofármaco en la industria alimentaria o biotecnológica.

El Huanglongbing (HLB, término de origen chino), enfermedad muy destructiva que afecta a los cítricos, ha disminuido la rentabilidad del limón en muchos países citrícolas. En México, el Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (INIFAP) generó un paquete tecnológico que contribuye al control del vector de la enfermedad y, mediante un adecuado manejo técnico, mantiene el vigor de los árboles infectados. El objetivo del presente trabajo fue determinar la rentabilidad, competitividad y eficiencia productiva del limón mexicano, en cultivos con convivencia con el HLB en Colima, a través de un análisis comparativo entre el paquete tecnológico tradicional y el del INIFAP. Se aplicó la Matriz de Análisis de Política (MAP). La información se obtuvo de registros de huertas experimentales y se complementó con 40 encuestas a agricultores con huertas coexistiendo con HLB: 20 a usuarios del paquete INIFAP y 20 del paquete tradicional. Ambas tecnologías fueron rentables, con la tradicional se obtuvo 95 % de ganancia y con el paquete INIFAP fue de 115 %. La RCP (relación de costo privado) del paquete INIFAP (0.36) indicó mayor competitividad comparada con el paquete tradicional (0.44). La cosecha de limón fue rentable y competitiva, aunque se evidenció la desprotección de las políticas económicas a los sistemas de producción locales. La adopción del paquete tecnológico de INIFAP mitigó la afectación de HLB y mejoró el rendimiento en la región de estudio.

La lactancia materna (LM) tiene beneficios en la salud del binomio madre-hijo. El abandono y las barreras para realizar la práctica de amamantar se relacionan con cuestiones biológicas, ambientales, culturales, sociales e individuales, entre otras. Todas ellas tienen influencia del conocimiento y actitudes que se adquiere durante la vida. La población universitaria, es una generación de adultos que forman un criterio integral sobre LM en función de la dinámica social. El objetivo del presente trabajo fue analizar el nivel de conocimiento y las actitudes de los estudiantes universitarios respecto a los beneficios de la lactancia materna en la salud. Se observó bajo nivel de conocimiento entre la población universitaria sobre aspectos de importancia tales como, la duración de la LM exclusiva, la reducción del riesgo en el desarrollo de obesidad, infecciones de oído, diarrea o alergias alimentarias, especialmente en estudiantes que no fueron del área de la salud. Respecto a las actitudes, se identificó una alta aceptación social de la práctica de la LM. Sin embargo, los estudiantes consideran a la alimentación con fórmula como una opción más práctica. Es necesario realizar investigaciones que integren diversos sectores de la sociedad que permitan explicar los cambios en acciones y comportamientos hacia la LM.

La situación de inseguridad ocasionada por el crimen organizado representa un problema para la actividad turística al intervenir en la decisión de visitar un destino. Particularmente, cuando el destino está cercano a zonas con antecedentes de actividades ilícitas relacionadas con el narcotráfico, como es el caso de Mazatlán, en México. El objetivo de este trabajo fue analizar las motivaciones turísticas sobre la intención de visita a la ciudad de Mazatlán, Sinaloa, ante la situación de inseguridad por el narcotráfico. A través de una investigación cuantitativa de alcance explicativo, se encuestó a 453 turistas nacionales y extranjeros; y los datos obtenidos se trataron con la modelación de ecuaciones estructurales por mínimos cuadrados parciales (PLS-SEM) y otras técnicas estadísticas. Los resultados muestran que, a pesar de la situación de inseguridad por el narcotráfico, las motivaciones pull inciden con mayor fuerza que las push. Sin embargo, ambas tienen una capacidad y relevancia predictiva fuerte. Por otro lado, la condición de inseguridad por el narcotráfico influye en la conducta de los encuestados y, por tanto, se asumen comportamientos de prevención y cuidado en los espacios que concurren. Asimismo, los extranjeros perciben en menor grado los estragos ocasionados por el crimen organizado y tienen mayores motivaciones pull y push; en consecuencia, su intención de viaje a este lugar es más alto que el de los mexicanos. Se concluye que en Mazatlán, independientemente de la posibilidad de escenarios de peligro emanados por el narcotráfico, existen estímulos que impulsan la estancia vacacional. Los aportes de esta investigación pueden ser de apoyo en el desarrollo de estrategias de comercialización y seguridad de los destinos, para atraer más viajeros.

Numa época em que as economias que sustentam o sistema financeiro e empresarial são abaladas por graves crises sistémicas e fraudes financeiras, surge uma pressão política cada vez mais acentuada ao nível do escrutínio da diversidade do conselho de administração (CA) das empresas, no sentido de perceber se, de facto, um grupo heterogéneo é capaz de produzir decisões estratégicas e táticas mais adequadas para o futuro da empresa. A par disto surgem questões relativas ao papel da Mulher no CA, concorrendo para a ideia de que esta poderá contribuir positivamente na gestão empresarial. Neste contexto, o presente estudo tem por objetivo analisar e caraterizar a diversidade do CA das empresas cotadas no PSI-20 em 2019. Especificamente, pretende-se analisar a diversidade à luz dos mecanismos formais de Governo das Sociedades de caráter interno sob quatro dimensões: (i) diversidade de género; (ii) diversidade etária; (iii) diversidade cultural/étnica; e (iv) diversidade na estrutura (independência e dualidade de funções CEO/Chairman). Para atingir este objetivo, o estudo alicerçou-se numa recolha de dados qualitativos e quantitativos com base nos Relatórios e Contas para o ano de 2019, permitindo analisar o perfil de 215 administradores. Concluiu-se que o CA das empresas que integram o PSI-20 é composto maioritariamente por elementos do género masculino, embora se note uma tendência crescente para a presença do género feminino. Verifica-se que a média das idades das mulheres é inferior à dos homens. Relativamente à diversidade cultural/étnica, prevalece uma maior representação de outsiders no CA de empresas não-familiares. No que se refere à estrutura do conselho, destaca-se a existência de uma relação de proporcionalidade adequada entre administradores executivos e não executivos. O mesmo não acontece com administradores independentes. Destaca-se, por outro lado, o facto de em 50% das empresas haver separação entre a figura do Chairman e do CEO, em que se depreende um incentivo para que o modelo de governação seja mais transparente e equilibrado, proporcionando um maior equilíbrio de poder.

Authors: Pedro Rui , Pedro Cristina
Published: July 2021

A rápida proliferação do turismo de saúde e bem-estar conduziu à difusão do número de spas, nos quais, é notória a inexistência de normas e de transparência na oferta deste tipo de produto e serviços, sobretudo ao nível dos empreendimentos turísticos. Este documento tem como principais objetivos contribuir para a criação de uma matriz inovadora de classificação spas em empreendimentos turísticos e para a igualdade da oferta de produto e serviços de spa, com o intuito de proporcionar uma ideia clara ao turista sobre o que esperar em cada categoria de spa. Os dados foram analisados com a técnica de Delphi em duas rondas, com 25 gestores/especialistas de spa na primeira ronda e 23 gestores/especialistas de spa na segunda ronda. Os resultados mostraram uma clara diferenciação entre categorias de spa em função do tipo de equipamentos, número de equipamentos, áreas, tratamentos/serviços, brochura, lista de preços, procedimentos de serviço e competências de gestão de spa necessárias. Esta classificação inovadora pode contribuir para a definição de normas de spa, segmentação do mercado, igualdade na oferta de spa, construção/edificação de spa, estratégia de marketing e gestão de spa.

Authors: Dantas Albino
Published: July 2021

A autenticidade é um tema cada vez mais presente nos debates acerca do Patrimônio. Entretanto, ambiguidades com outros conceitos igualmente fundamentais como originalidade e integridade mostram que o que é “autêntico” merece uma atenção mais detalhada. O presente artigo se propõe a uma interpretação da autenticidade como Valor por meio da desambiguação entre as noções observadas de ‘autêntico-como-original’ e ‘original-como-autêntico’. Em seguida, apresenta a estruturação de uma concepção de Autenticidade baseada em lógica formal e discute o papel do pesquisador como agente articulador das noções apresentadas em seus contextos históricos e paradigmas científicos.
