Modern medical advances allow us to expand a range of combined surgical interventions. The literature to this day does not cover issues regarding the implementation of typical options for combined operations with deformities of the nasal septum, structures of the lateral wall of the cavity, nose, pathological processes in the hole of the paranasal sinuses; with perforated odontogenic maxillary sinusitis; racemose, sprains of the paranasal sinuses, combined with damage to the orbit. Since during combined operations the mucous membrane in various parts of the nasal cavity is injured to one degree or another, the problem of prevention and treatment of postoperative traumatic rhinitis is extremely important.

Si el consumo de leña es desfavorable para el medio ambiente de las ciudades, ¿sucede esto en Oaxaca? El objetivo de este artículo es analizar, para el periodo 2000-2015, si el desarrollo sustentable de 17 de las ciudades de mayor población, que cumplen la función de lugar central en Oaxaca, México, se ve influido desfavorablemente por el uso de la leña en los hogares. Para ello, con datos documentales se han creado índices de desarrollo sustentable y vivienda con uso de leña, aplicando los análisis estadístico bayesiano, de regresión, y de redes. Los resultados indican que si aumentan los niveles de desarrollo de las ciudades, esto mismo sucede con el consumo de leña.
Agua en la Ciudad de México: deseconomías de escala y tecnologías intermedias
Authors: Fraga Castillo Carlos A.
Published: July 2021

El objetivo de esta investigación es examinar teórica y empíricamente las deseconomías de escala y las tecnologías intermedias en el sector del agua en la Ciudad de México. La concentración demográfica de esta ciudad puede disminuir los costos promedio de bienes públicos como el agua; sin embargo, hasta cierto nivel, ellos pueden crecer y llevar a deseconomías de escala. La producción y la distribución de agua generan en cada caso costos diferentes; los que se pretenden estudiar en esta investigación son los de producción. Este trabajo contribuye con la presentación de indicios teóricos y estadísticos de que la tendencia a las deseconomías de escala en la producción de agua en la Ciudad de México, observada desde los años setenta, continúa, y si esta puede atenuarse con tecnologías intermedias.
Gobernanza de la expansión: infraestructuras transnacionales de energía en América Latina
Authors: Jenss Alke Christine
Published: July 2021

Las transformaciones hacia infraestructuras “ecológicas” están íntimamente ligadas a conflictos sociales. Para enriquecer el debate sobre estas expansiones infraestructurales en disputa, relaciono análisis de economía política y ecología política con la literatura sobre “políticas de operación” y logística. Para ello se analiza la infraestructura de energía renovable del Proyecto Mesoamericano, el cual fomenta nuevos “territorios transnacionales” e implica un creciente papel de corporaciones globales en las luchas sociales locales. El argumento central es que la impugnación de tales proyectos ha sido complicada por la creciente priorización de la circulación (nodos de infraestructura, corredores de energía) de las políticas de seguridad, que incluso inducen el desplazamiento de personas.

Da periferia do aprendizado à centralidade do que somos: diálogo Brasil-Moçambique
Authors: De-Carvalho Roberth , Cuchedza Adamo Devi
Published: July 2021

Ex-colônias portuguesas, a Colônia do Brasil do Reino de Portugal (entre 1500-1822; Brasil) e a África Oriental Portuguesa (1501-1975; Moçambique) foram/são palcos de lutas e resistências que buscam outro tipo independência simbólica: descolonizar-se para reconectarem a suas origens. Do ranço de economias baseadas no tráfico da natureza (humana e não-humana), de saberes científicos, de técnicas e de tecnologias, a naturalização de ideias hipermercantilizadas insiste no espaço e no tempo da produção de múltiplas colonialidades. Por atravessarem áreas das Ciências da Natureza e da Matemática, destacamos como principal objetivo deste ensaio dialogar com nossas próprias histórias, despertando educadores em Ciências e em Matemática, ou de quaisquer outros campos de conhecimento, a deflagrarem condições de significação política, afetiva e ideológica em seus saberes-sentidos escolares. O resultado de nosso ‘diálogo de saberes’ aponta caminhos para revisionar o Ensino de Ciências e de Matemática na escola básica do Sul global.

Published: July 2021

Trata-se de uma pesquisa documental descritiva do tipo retrospectiva com abordagem quantitativa, considerando os meses de março a junho de 2020, com o objetivo de demonstrar as expressões de luto em veículos de comunicação acerca da COVID-19. Foram coletadas e analisadas matérias dos 12 principais jornais de circulação no país, a saber: Zero Hora; A Tarde; UOL; O Povo; Estado de São Paulo; Correio Brasiliense; R7; O Globo; Super Notícia; G1; Terra; Folha de São Paulo. Foram selecionadas 67 matérias, das quais o R7 teve 11,9%, seguido do UOL, com 10,4%. Em relação ao mês das publicações pelos jornais: março com apenas 1,5%; abril 25,4%; maio 43,3% e junho 29,9%. Quanto aos tipos de recorte, 56,7% dos escritos eram notícias, 28,4% reportagens e 14,9% entrevistas. Os tipos de luto mais comuns foram, por morte apresentando 85,1%, perda de algo estimado 13,4% e perda da rotina 1,5%. Dos tipos de expressões a religiosa alcançou 23,9%, seguida de emocional 20,9%, política e outros, ambos com 17,9%. Evidenciou-se que na mídia, o luto ainda é um tabu, recebendo pouco destaque e aparecendo como tema relevante apenas em situações de tragédias (vidas perdidas). As expressões óbitos e perdas estavam sempre conectadas ao findar-se da vida, ainda que, durante a pandemia se tenha também mortes de sonhos, trabalhos, qualidade de vida, e inúmeras outras coisas que talvez não tenham como serem refeitas ou substituídas.

Chayotextle flour as raw material of prebiotic gluten-free cookies added with Agave angustifolia Haw fructans
Authors: Quintana Zavala Delia
Published: July 2021

Some plants, roots or tubers have been used as possible cereal substitutes in gluten-free cookies. Chayotextle is rich in starch and other compounds that could make it a potential ingredient for products aimed at the celiac population. In this study, the effect of different mixtures of rice flour (RF) and Chayotextle flour (CF) on the final properties of cookies and the prebiotic capacity when adding agave fructans (AF) was evaluated. Flour properties (water and oil absorption, emulsifying capacity) and cookies (diameter, thickness, specific volume, color, hardness and prebiotic capacity) were determined. CF presented higher emulsifying capacity, absorption of water and oil (27.1 %, 66.22 % and 95.93 %, respectively). The cookies with CF and AF reached the highest values in physical properties (65.10-66.82 mm in diameter, 9.36-10.04 mm thickness, 1.72-2.07 mL/g specific volume and 201.82 N in hardness). CF and the CF-AF formulation showed ability promoted the growth of both strains studied: Lactobacillus acidophilus LA-3 and Bifidobacterium animalis ssp. Lactis, reaching values of up to 9.82 log10 CFU/g and 9.85 log10 CFU/g (CF) respectively, in a period of 24 h. The CF and the addition of FA improved the properties of the cookies and proved to be a possible prebiotic source.

Authors: Vasquez Lara Francisco
Published: July 2021

La harina de avena fue tratada térmicamente a 80, 100 o 130 °C durante 30 min para después ser utilizada en la sustitución del 10 o 20 % de harina de trigo para la elaboración de pan. Se determinó capacidad de retención de agua, perfil de viscosidad, volumen específico, pérdida de peso, actividad de agua y análisis de perfil de textura a los días 0, 2 y 7 después de elaborado el pan. Los parámetros de viscosidad fueron afectados por el nivel de sustitución de harina de avena y el tratamiento térmico, siendo más notable cuando la harina de avena se trató a 130 °C. Al utilizar harina de avena tratada a 100 °C, el volumen específico de pan aumentó, incluso más que al observado en el pan de harina de trigo (2.22 cm3/g). Esto sucedió para ambos niveles de sustitución 10 o 20 % (2.64 y 2.75 cm3/g). El perfil de textura, también se vio afectado por el nivel de sustitución y el tratamiento térmico. A los 7 días de almacenamiento, la firmeza del pan disminuyó cuando se usó 10 % de harina de avena tratada a 130 °C (12.86 N) con respecto al elaborado de harina de trigo (19.63 N). Los tratamientos térmicos en harina de avena utilizada en la sustitución de harina de trigo, pueden ser una alternativa importante para mejorar las propiedades reológicas, texturales y de calidad del pan.
The Condition of Companies and their Growth Based on the Example of Companies Included in WIG and DAX Indices
Authors: Bolek Monika , Gniadkowska-Szymańska Agata
Published: July 2021

The purpose of the article/hypothesis: The paper discusses the problem of condition of companies together with their growth measured by earnings per share, sales, assets and equity. The condition of a company in a capital market is considered good when the goal of the business is achieved, namely the increase of value that occurs with the increase of earnings per share. We assume that the condition of companies measured by Altman’s Z-score Model scores is related to their growth, and ratios applied in this model influence the growth of companies measured by EPS, sales, assets and equity. The research is conducted in two groups of companies, one representing WIG listed entities and the other one comprising DAX listed companies.

Methodology: The growth of earnings per share is considered as a measure of companies’ value creation. The growth of EPS should be related to the growth of sales, assets and equity according to the growth theory. To analyze the influence of Altman’s Z-score Model on the growth of EPS, sales, assets and equity, the Pearson and Spearman correlation is applied in the first place. Moreover, logit models are applied to analyze the influence of ratios composing the Altman’s Z-score Model on the growth of EPS, sales, assets and equity.

Results of the research: Discriminant models can be applied for the assessment of the economic condition of companies but the interpretation of the results should take into account the fact that risky strategies identified by Altman’s Z-score Model as dangerous are related to the higher growth of earnings per share, therefore, there should be a negative relationship between Altman’s Z-score Model scores and EPS growth and it was confirmed in this study.

This study aimed to determine the degree of practicing authentic leadership among public-school leaders from teachers’ viewpoint while also revealing whether statistically significant differences exist between the respondents’ means of the degree of authentic leadership practice due to number of years of service, specialization, and/or scholastic stage. A descriptive-analytical approach was adopted. The study population consisted of teachers. A stratified random sample of 351 female teachers was chosen. The questionnaire used consisted of four main axes that included the four authentic leadership elements: self-awareness, relational transparency, the internalized moral perspective, and balanced processing. The results indicated a high degree of the practice of the four dimensions of authentic leadership among the leaders as well as the presence of statistically significant differences between teachers’ mean responses about the degree of authentic leadership practice among the leaders of public-schools due to the number of years of service in favor of the teachers whose years of service ranged between 5 and 10 years as well as academic level in favor of intermediate school teachers. The researchers also offer several recommendations.

McDowell y el realismo ingenuo. Mind and World ante el argumento por la ilusión
Authors: Saharrea Juan
Published: July 2021

Mediante el análisis conceptual el artículo reconstruye algunos aspectos de Mind and World de John McDowell, orientados a ampliar el rol explicativo de la tesis de la “carencia de límites de lo conceptual”. Para esto se vincula dicha tesis, que corre el riesgo de ser objeto de la objeción de idealismo en sus variantes “más perniciosas”, con la idea de percepción como “apertura al mundo”, que niega decididamente un idealismo semejante. Si bien la defensa del rol justificatorio del contenido perceptivo da cuenta de esta última tesis, no muestra, al menos explícitamente, relaciones posibles con la primera. Este artículo, en cambio, propone resolver esta tensión. Así reconstruye la posible respuesta del conceptualismo de McDowell al argumento por la ilusión. De este modo, a partir de la distinción entre posibilidad ordinaria de error perceptual y posibilidad en principio de error perceptual –derivada del tratamiento de McDowell sobre la incorregibilidad perceptual– se concluye que la “carencia de límites de lo conceptual” y la afirmación de que ordinariamente la percepción nos proporciona conocimiento directo de hechos del mundo, no son incompatibles desde la perspectiva de la posibilidad ordinaria.

Mutual funds are a forum for fund owners/investors to invest their funds in securities portfolios by the Investment Manager, in other words, the investment manager has an important role in managing investors' funds. Moreover, the funds managed by the investment manager are very large, however, the regulation regarding this matter is deemed inadequate so it is not uncommon for investment managers to neglect by ignoring the rights of investors which cause investors to suffer losses and are not protected. The issues that will be discussed are how the legal protection provided to mutual fund investors and the responsibilities of investment managers who default on losses suffered by investors. Based on these issues, the purpose of this research is to find out the legal protection for mutual fund investors who suffer losses due to errors from investment managers. This research uses an empirical legal research method by using the data collection techniques through interviews. From the data obtained, it shows a form of protection that given provided to investors is in the form of opened information. The investment manager will be responsible for the losses suffered by the investors, but is not more than the fee given by investors to the investment manager. If the investors’ report is not responded to, or Bapepam’s action against the investment manager which is proven to be inadequate for investors, then investors can file a lawsuit against the law through the district court. Investors must have sufficient evidences to prove the investment manager’s negligence which resulted in losses.

Chemical calculation is the most important subject in learning chemistry but it is difficult understand for some students. Students will master chemistry well if this subject has been mastered well. Therefore, it is necessary to analyze student errors in mastering this material to assist students in their learning. This study aims to identify patterns of student error in solving chemical calculation problems. Students' conceptual errors were analyzed using the Newmann procedure. The error patterns analyzed include several errors, namely Reading, Comprehension, Transformation, Process Skills, and Encoding. Most of the students experienced a pattern of transformation errors on each item given. The largest percentage of transformation errors is in question number 3, which is 52.5%. This shows that the ability of students is still weak in solving problems related to chemical calculations. This study suggest that chemistry teachers emphasize more on students about the correct approach in solving chemical calculation problems.
The Legal Status of a Scientist As a Factor in the Scientific and Technological Development of Russia
Authors: Vasilev Anton , Putilo Natalia
Published: July 2021

The article raises the problem of the legal status of a scientist as a special subject of legal relations in the field of science. The authors note the lack of unity and consistency of Russian law in the use of terms to designate persons who conduct research activities. Various terms are used in bylaws: leading scientist, young scientist, scientific and pedagogical worker, scientific worker, etc. The lack of uniformity leads to the erosion of the concept of a scientist, a researcher. The paper substantiates the thesis of the need to formalize the term “scientist” at the level of the basic law on science and innovation. The decisive criterion for qualifying a person as a scientist in the article proposes the presence of the results of scientific and (or)scientific and technical activities recognized in the established manner. This approach allows a wider range of researchers to be included in the number of scientists, who may not have documents on scientific qualifications. The article presents the classification of researchers on various grounds. Particular attention is paid to the rights and duties of scientists, there is a correlation between the growth of ethical requirements and the importance of the profession of a scientist and the level of their social and material well-being. The need to improve the status and prestige of the profession of a scientist in the Russian Federation is noted.

Published: July 2021

This paper presents an approach to evaluating the role of research universities in national scientific and technological development. It includes an analysis of the level of human capital concentration in the world’s leading research universities and their contribution to the making of new scientific knowledge. It shows that over the recent decades, the governments of many countries have been putting a lot of effort into building national networks of competitive world-class research universities as part of academic excellence programmes. The focus is on the experience of France (COMUE), Germany (Excellence Strategy), Republic ofKorea (Brain Korea) and China (Double First World Class). The paper shows that the key global university rankings are based on a research university model, with changes in the ranking positions indicating national governments’ efforts to concentrate human capital in leading research universities. Evaluation of the economic efficiency of the Russell Group universities (the UK) serves to show the impact of the third mission of a university on national economy and society. Leading research universities are regarded as a basis for meeting the demands of their national economies for highly qualified staff, new scientific knowledge, technology and innovation, which are vital for speeding up the rate of scientific and technological as wellas social and economic development.

Se trata de una iniciativa de Marca Púrpura, asociación de mujeres arquitectas canarias, cuyo objetivo general es el de aprender y profundizar colectivamente en la cuestión del género y en particular en su relación con los campos disciplinares que les son propios, la arquitectura y el urbanismo. Se plantea a modo de programa a desarrollar en sucesivos formatos. Se inició con el Encuentro Internacional GAC: Género, Arquitectura y Ciudad, que tuvo lugar en el mes de mayo de 2019 en Las Palmas de Gran Canaria, cuyo contenido general es la base de la presente publicación. Y se pretende continuar próximamente, con diversas actividades, entre ellas, la convocatoria de un Seminario-Taller, de formato más práctico. El Encuentro Internacional GAC: Género, Arquitectura y Ciudad ofreció un espacio de exposición y debate disciplinar que permitió avanzar en el acercamiento a la integración de la condición de género o perspectiva de género tanto en la articulación teórica y conceptual, como en el ejercicio práctico de la arquitectura y el urbanismo. Contó con relevantes arquitectas de reconocimiento internacional como ponentes invitadas, así como con convocatoria de comunicaciones para personal investigador, además de la exposición de experiencias en marcha desde diversas asociaciones o colectivos, a lo que se sumó la participación amplia y plural de profesionales y docentes, así como de la ciudadanía interesada en la construcción de la ciudad. El Encuentro Internacional se organizó en tres bloques temáticos, sobre: urbanismo feminista, espacio libre con perspectiva de género y espacio construido con perspectiva de género; estructura que se mantiene en la presente publicación.

Competition in the field of education globally is increasingly competitive, but it has not been directly proportional to the development of education in several regions in Indonesia. Students still have difficulty in critical thinking, including the concept of classification of living things, because the teaching materials used are not fully related to the experience and environment of students. This study aims to develop teaching materials for the concept of classification of living things based on local potential. The development is carried out using Tessmer's formative model which includes five stages; 1) self-evaluation (self-evaluation); 2) expert opinion (expert review); 3) Individual trial (one to one); 4) small group trial; and 5) field test. The results showed that by developing a prototype of contextual teaching materials based on local advantages, it was able to increase students' interest, activity, and thinking skills which could be measured by increasing their learning outcomes.Abstrak Persaingan di bidang pendidikan secara global semakin kompetitif, namun belum berbanding lurus dengan perkembangan pendidikan di beberapa daerah di Indonesia.
