RATIONALE: Insufficient world–wide clinical experience in radioiodine therapy (RIT) for Graves’ disease (GD) in children and adolescents, and limited knowledge of the predictors of RIT efficacy.

AIMS: Analysis and identification of the most significant predictors of the efficacy of RIT in children and adolescents with Graves’ disease.

MATERIALS AND METHODS: A total of 55 patients (48 females and 7 males) aged from 8 to 18 years receiving primary RIT for GD were enrolled. RIT planning was based on the dosimetric method. Analyzed parameters included gender, age, ultrasound thyroid volume before and 6 months after treatment, the presence of endocrine ophthalmopathy, duration of antithyroid drug (ATD) therapy, relapse of thyrotoxicosis after ATD dose reduction, blood fT3, fT4 and TSH levels initially and at 1, 3, 6 months after treatment, TSH receptor Ab initially and at 3 and 6 months after treatment, thyroid 99mTc–pertechnetate uptake at 10–20 minutes (%), maximum thyroid 131I uptake (%), specific 131I uptake (MBq/g) and therapeutic 131I activity (MBq). Fisher exact test, non–parametric Mann–Whitney test, Wilcoxon signed–rank test, logistic regression modelling, ROC–analysis, proportional hazard model (the Cox regression), the Kaplan–Meier method and log–rank test were used for statistical analysis as appropriate.

RESULTS: Six months after RIT, hypothyroidism was achieved in 45 (81.8%), euthyroid state – in 2 (3.6%), and in 8 (14.6%) patients thyrotoxicosis persisted. On univariate statistical analysis, the smaller thyroid volume, higher fT4 and lower TSH receptor Ab levels, lower 99mTc–pertechnetate uptake and higher specific 131I uptake were associated with hypothyroidism. On multivariate logistic regression analysis, the older patient’s age (p=0.011), smaller thyroid volume (p=0.003) and higher fT4 (p=0.024) were independent predictors of RIT efficacy. Thyroid volume was also the only variable associated with achievement of hypothyroidism in time after RIT (p=0.011).

CONCLUSION: The efficacy of dosimetry–based RIT in children and adolescents with GD 6 months after treatment was 81.2%. Older patients’ age, smaller thyroid volume and higher fT4 level were independent predictors of therapy success. Smaller thyroid volume was also a predictor of the favorable time–related outcome. Statistical models obtained in this work may be used to prospectively estimate the chance of efficient RIT for GD in pediatric patients.
Entrepreneurial Leadership and Innovative Work Behavior: The Role of Creative Self-efficacy
Authors: Sarwoko Endi
Published: December 2020

Several previous studies have tested the relationship between leadership type and innovative work behavior. However, there have been only a few empirical studies examining the mediating role of creative self-efficacy on the relationship between entrepreneurial leadership and innovative work behavior. This study was conducted to fill this gap to understand the relationship between entrepreneurial leadership and innovative work behavior and the role of creative self-efficacy as a mediating variable for the relationship between entrepreneurial leadership and innovative work behavior. Data were collected using a questionnaire distributed to 190 employees of the Astra Honda Authorized Service Station (AHASS) and analyzed using Structural equation modeling with SmartPLS software. The results indicate that entrepreneurial leadership increases the innovative work behavior of employees. Besides, entrepreneurial leadership increases creative self-efficacy and leads to increased employee innovative work behavior. This study contributes to the development of the literature by providing empirical evidence on the relationship between entrepreneurial leadership and innovative work behavior and the role of creative self-efficacy in innovative behavior. This study confirms Social Cognitive Theory (SCT) that a person's self-efficacy will generate creative ideas in the workplace and produce innovative work. The practical implication is that leaders must provide greater opportunities for employees to develop creative ideas in the workplace to achieve an increase in innovative work behavior.
MODEL GERAKAN DAKWA KEAGAMAAN MUHAMMADIYAH: Studi Etnografi di Kabupaten Sidoarjo Jawa Timur
Authors: Mocham Puspita Handayani, Ima Faizah, dan
Published: December 2020

Muhammadiyah is one of the two biggest Islamic organizations in Indonesia. Since it was founded on November 18, 1912 in Yogjakarta by K.H. Ahmad Dahlan, Muhammadiyah is known as the Islamic missionary movement of 'Amar ma'ruf nahi munkar (invite to do good and prevent evil deeds) to broadcast Islamic teachings from a humanist point of view and return to the Al-Qur'an and Hadith. Because of this model, Muhammadiyah becomes less attractive for most Muslim community, due to the religious patterns of the Javanese people that are heavily influenced by Hindu and Buddhist traditions that are mixed within Islamic practices of Javanese Muslims. The purpose of this study is to determine the model of the Muhammadiyah religious da'wah movement in Sidoarjo Regency. By using a qualitative approach through ethnographic model, this paper aims to describe the conditions of the Muhammadiyah religious missionary movement. This research is limited to understand how the model of the Muhammadiyah religious da'wah movement at the Muhammadiyah regency and district branches in Sidoarjo Regency. The results show that the model of the religious da'wah movement of Muhammadiyah in the regency of Sidoarjo is originated come from a social movement, namely taking real actions to help the surrounding community. Muhammadiyah  merupakan salah satu dari dua organisasi Islam besar di Indonesia. Sejak didirikan pada 18 Nopember 1912 di Yogjakarta oleh K.H. Ahmad Dahlan Muhammadiyah dikenal dengan Gerakan dakwah Islam ‘Amar Ma’ruf Nahi Munkar (mengajak kepada kebaikan dan mencegah kemungkaran) untuk menyiarkan ajaran Islam dari sudut pandang yang humanis dan kembali kepada Al-Qur’an dan Hadits, karena model gerakan ini membuat Muhammadiyah kurang diminati oleh masyarakat muslim pada umumnya, disebabkan pola keagamaan masyarakat Jawa yang kental dengan tradisi-tradisi peninggalan Hindu dan Budha dikolaborasi dalam nilai-nilai kerohanian Islam. Tujuan dari penelitian ini adalah mengetahui model gerakan dakwah keagamaan Muhammadiyah di Kabupaten Sidoarjo. Dengan menggunakan pendekatan kualitatif model etnografi, bertujuan untuk mendiskripsikan kondisi gerakan dakwah keagamaan Muhammadiyah. Penelitian ini dibatasi pada bagaimana model gerakan dakwah keagamaan Muhammadiyah di tingkat ranting dan cabang Muhammadiyah di Kabupaten Sidoarjo. Ternyata dari hasil penelitian bisa ditemukan model gerakan dakwah keagamaan Muhammadiyah di tingkat ranting dan Cabang berawal dari gerakan sosial, yaitu melakukan aksi-aksi nyata membantu masyarakat sekitar.

Published: December 2020

A asma é uma doença crônica heterogênea, cujo tratamento é dividido entre a farmacoterapia de manutenção e a sintomática. O controle eficiente e prolongado das manifestações clínicas e funcionais da asma pode ser obtido pelo uso de corticosteroides, agonistas de beta-receptores de curta e longa duração, frequentemente incorporados a dispositivos inalatórios. Estudos destacam que o cuidado farmacêutico centrado no estabelecimento da autogestão do tratamento da asma se mostra promissor. O objetivo foi buscar evidências sobre intervenções farmacêuticas e seus desfechos relacionados à administração de dispositivos inalatórios para pacientes asmáticos. Trata-se de uma revisão integrativa e síntese narrativa. Foram localizados e incluídos nesta pesquisa oito artigos originais que apontam evidências de que as intervenções farmacêuticas são capazes de reduzir problemas relacionados ao uso de dispositivos inalatórios, proporcionando a autogestão do tratamento da asma. Conclui-se que as intervenções conduzidas por farmacêuticos melhoram o uso de inaladores, refletindo positivamente no controle da doença e reduzindo problemas relacionados a medicamentos.

Published: December 2020

O uso indiscriminado de antibióticos de um modo geral proporcionou o desenvolvimento de várias bactérias multirresistentes, as quais são responsáveis por infecções sistêmicas de grande importância clínica. O objetivo deste estudo foi descrever de forma narrativa a resistência antibiótica aos β-lactâmicos e sua administração combinada com outros fármacos visando a ressensibilização bacteriana de cepas multirresistentes. Trata-se de um estudo qualitativo de revisão narrativa, constituída por análise da literatura com busca de dados publicados na base de dados ScienceDirect sobre o tema “uso de inibidores β-lactâmicos para o tratamento de infecções causadas por bactérias multirresistentes”. Este estudo mostrou que há possibilidades de tratamento das infecções bacterianas causadas por cepas multirresistentes por meio de antibioticoterapia de inibidores β-lactâmicos. As infecções bacterianas multirresistentes continuam sendo um grande desafio para medicina, uma vez que existem enzimas que conferem resistência bacteriana contra todos os antibióticos. Mesmo que atualmente exista inibidores de β-lactamases disponíveis e com atividade antimicrobiana, é necessário que o esforço pela busca de novos antibióticos seja contínuo para o controle de bactérias multirresistentes.

Published: December 2020

Este trabalho buscou estabelecer um primeiro panorama dos pressupostos Freireanos na produção acadêmica do ensino Ciência Tecnologia e Sociedade, CTS, no Brasil, por meio da análise das principais palavras-chave e referenciais teóricos mais recorrentes pelos pesquisadores da área.  Os treze artigos analisados na pesquisa foram retirados no banco de dados do Grupo CTS e Educação do CEFET/RJ, que reúne 244 artigos sobre CTS, de 1996 a 2016, em 31 periódicos. O critério de seleção foi encontrar no título, resumo ou palavras-chave dos artigos, termos relacionados à pedagogia freireana. Num primeiro momento, investiu-se na análise de Rede Social, por meio das palavras-chaves e autores citados. Posteriormente, foi realizada uma leitura analítica nos artigos com objetivo de identificar como os saberes relacionados à abordagem desde Freire foram relacionados com o enfoque CTS. A discussão realizada no presente trabalho pode auxiliar no entendimento de como os principais campos teóricos de Paulo Freire são representados na abordagem CTS. Os resultados obtidos apresentaram evidências que levam à necessidade de análises teóricas mais profundas, mas mostram que as inter-relações entre Freire e CTS se fazem de maneira superficial e sem aprofundamento teórico.

Background: COVID-19 affecting the outcome of pregnancy is still under investigation. Here we report a case of primigravida with monochorionic diamniotic twin pregnancy with superimposed preeclampsia who develop symptoms of COVID-19 infection on her near term pregnancy and was confirmed later on as COVID-19 positive after cesarean section. The pregnancy was terminated abdominally due to the intrauterine fetal demise of both twins using COVID-19 standard equipment.Case Presentation: A 29-year-old female, gravida 1, para 0 presented with a twin pregnancy at the gestational age of 36 weeks was referred to our emergency department for further management of intrauterine fetal death of both twins. Six days before admitted to our emergency department, she has been experienced a remittent fever which followed by a mild cough. Four days before admission, she complained of decrease movement of the babies. She went to the Secondary Hospital to check her pregnancy and both fetal heart rates were not found.  The patient is obese (BMI 49.2 kg/m2) and had prior uncontrolled hypertension but no other medical history, including epilepsy, allergies, asthma, heart disease as well as Diabetes Mellitus.Conclusion: A research about placental pathology in pregnancy with confirmed case of COVID-19 infection showed no pathognomonic feature in the histopathologic examination but mostly, there were maternal vascular malperfusion (decidual arteriopathy in particular) and intervillous thrombi. In the end, a further examination is suggested to evaluate the course and causal factors pertaining to this case.

Published: December 2020

Gastric cancer has been known as the third leading cause of cancer-related death in the world. It is when cancer cells form on the lining of the stomach. Early symptoms include heartburn, upper abdominal pain, nausea, and loss of appetite. Helicobacter pylori is the most common microscopic creature that has infected humans worldwide. More than half of the world's population is infected with the bacterium. It is the main cause of diseases such as stomach ulcers and stomach and intestinal disorders. H. pylori infection is related to gastric adenocarcinoma and cagA genotype is believed to be related to cancer development. cytotoxin-associated gene A (CagA) is a 120–145kDa protein encoded on the 40kb cag pathogenicity island (PAI). This study investigates the association between cagA H. pylori genotypes and gastric cancer. For this purpose, 65 stomach biopsies of the gastric cancer patients and 100 saliva samples were collected from healthy and H. pylori-infected individuals. Then genomic DNA was purified and Polymerase Chain Reaction (PCR) was performed for the studied gene using specific primers. The presence of H. pylori was investigated by PCR and a pair of specific primers for a protected region in the bacterium glmM gene. Then cagA+ and cagA- genotypes frequencies were determined in H. pylori-infected cases. Statistical analysis showed that there were significant differences between healthy and diseased ones for genotypes cagA+ and cagA-. Then the cagA+ can be a risk factor genotype for gastric cancer.
Estimation levels of prostate-specific antigen, interleukin-8, oxidative stress and some inflammatory markers in sera of benign prostatic hyperplasia patients who have smoking habits as a risk factor
Authors: Al-Barzinj Ruqaya Mohammed Ghareeb Taher
Published: December 2020

Benign prostatic hyperplasia (BPH) is a common multifactorial inflammatory disease of older men, defined by increased growth of prostate epithelial and stromal cells. Elevation serum levels of Interleukin-8 (IL-8), oxidative stress and inflammatory markers represent predictive surrogate markers of the disease progression in smoker BPH patients. A total of 86 BPH patients and 54 control subjects were admitted to the urology unit, Rizgary Teaching Hospital in Erbil City, Iraq between January and June 2020. Sera levels of prostate-specific antigen(PSA), IL-8, malondialdehyde (MDA), high sensitive C-reactive protein (hs-CRP), testosterone and some biomarkers concentrations were measured in the patients according to instructions of manufacturers. Patients and controls were categorized into groups according to smoking status (smokers and non-smokers). The sera levels of PSA, IL-8 and inflammatory markers like oxidative stress(MDA), hs-CRP and testosterone in every smoker subgroup (BPH patients and control) increased compared to the same non-smoker subgroups and significantly increased compared with non-smoker control (p<0.05). PSA demonstrated a significant positive correlation with the following terms, IL-8, MDA, hs-CRP, testosterone and low-density lipid (LDL)(p<0.05) and, insignificant negative correlation with high-density lipoprotein(HDL), (p>0.05). The current study demonstrated mounting evidence to support the role of smoking in the pathophysiology of BPH through elevation levels of inflammatory and oxidative stress biomarkers in sera of BPH patients.

Published: December 2020

This study aimed to explore the expressions of interleukin-12 (IL-12) and its receptors IL-23R and IL12RB2 in patients with lumbar disc herniation (LDH) before and after treatment and their relationship with clinical efficacy. A total of 172 LDH patients undergoing surgical treatment in Wuhan Third Hospital, Tongren Hospital of Wuhan University were enrolled as the study group, and 170 healthy subjects as the control group. 5 mL of fasting venous blood was taken before surgery (T0), 1 d (T1), 3 d (T2), 5 d (T3) and 7 d (T4) after treatment respectively. The concentrations of IL-12, IL-23R and IL12RB2 in the two groups were detected, and the correlation between them and the treatment duration and clinical efficacy was analyzed. The study group showed significantly higher serum IL-12, IL-23R and IL12RB2 than the control group before treatment (P < 0.001). In the study group, IL-12, IL-23R and IL-12RB2 were the lowest at T4 (P < 0.001), followed by T3 (P < 0.001). There was no significant difference in IL-23R at T1 and T0 (P > 0.050), and in IL12RB2 at T1 and T2 (P > 0.050). Spearman rank correlation showed that IL-12, IL-23R, IL12RB2 were negatively correlated with treatment duration in the study group (P < 0.001), and were positively correlated with clinical efficacy (P < 0.001). In conclusion, the concentrations of serum IL-12, IL-23R and IL12RB2 in LDH patients are significantly higher than those in normal controls. Moreover, the concentrations are closely related to the rehabilitation of patients and are expected to become therapeutic targets for LDH.
Application of intravoxel incoherent motion imaging in the study of migration and movement of cancer cells
Authors: Wang Yilei , Xu Haixiao , Ahmed Idris Jerjes
Published: December 2020

IVIM imaging technology can obtain physiological information of tissue cells and blood perfusion at the same time in one imaging process. Taking female patients in Shenzhen Maternal and Child Health Hospital affiliated to Southern Medical University as an example, the migration and movement of breast cancer cells and hepatocellular carcinoma cells are studied by intravoxel incoherent motion imaging. Apparent diffusion coefficient (ADC), true diffusion coefficient (D), pseudo-diffusion coefficient (D*) and perfusion fraction (f) are measured by the IVIM bi-index model, and statistical analysis is made. The results show that the IVIM bi-index model can truly reflect the diffusion of water molecules in breast mass-like lesions, and reflect the migration and movement of breast cancer cells. Especially D value has important reference significance for the research and diagnosis of breast cancer cells. IVIM bi-index model has limited diagnostic value for the migration and movement of common hepatocellular carcinoma cells, and ADC value may have higher diagnostic efficiency.
Towards developing the skill of transcommunicating among tertiary education students: the role of study abroad programmes
Authors: Bielak Marlena Iwona
Published: December 2020

The objective of the paper is to highlight the need of adjusting the skills of tertiary education graduates to the requirements of the present global world, which entails the idea that higher education should be aimed at developing abilities that will facilitate communicating within and across a variety of communities, ethnicities and cultures. In the paper it is postulated that tertiary education graduates should be equipped, inter alia, with the skill of transcomunicating based on the idea of equality of cultures and languages. Due attention is paid to the role of study abroad programmes in the aforementioned process. Accordingly, the research part of the paper delves into the influence of the Erasmus+ mobility on the development of transcommunication among tertiary education students and rests on the analysis of the material gathered during interviews with learners who participated in the international student mobility conducted within The Erasmus+ Framework. The research results point to the key role of experiential learning held in territorial contexts in the process of developing the skill of transcommunicating among the research participants.

The paper presents language policy in Sweden from 16th to 21st century. During many centuries Sweden aimed at making Swedish the dominant language in every domain and for every national group living in Sweden. Currently, Swedish has been recognized as the main language in Sweden which implicates the use of other languages in the country. Many activities are carried out in order to make the language used in public institutions easy and intelligible. Sweden offers courses in Swedish for immigrant children and adults, as well as courses in minority languages spoken as first languages and in sign language. There are also many institutions in Sweden which act in order to cultivate and promote Swedish.
Image, or what? an attempt towards a holistic exploration
Authors: Puppel Stanisław , Puppel Joanna
Published: December 2020

The following is a proposition paper whose purpose is to try to provide a solid theoretical (modelling) background for research on image generation and image maintenance. As such, it is intentionally devoid of any experimental/empirical findings. And although we agree that model-reasoning is difficult to observe, we nevertheless utterly agree with Rosenblueth and Wiener’s stance according to which ‘scientific knowledge consists of a sequence of abstract models, preferably formal, occasionally material in nature (Rosenblueth/Wiener, 1945,320), who further also stated that ‘the ideal model would be one which would cover the entire universe’ (Rosenblueth/Wiener, 1945,320). We are, of course, convinced that material substance can and should be provided later on as research continues to accrue with reference to the model(s) proposed.General assumptions which are put forth in the paper are the following:1. image is pervasive in nature; in fact, in humans it is more pervasive than language. This is due to the fact that the visual-tactile modality is of fundamental significance in the daily conduct of the human species (see e.g. Fletcher, 1952; Pirenne, 1967; Schiffman, 1982; Gordon, 1989; Sekuler/Blake, 1994).2. Owing to its pervasiveness, image may be approached holistically, that is, it may be likened to life, especially to its exteriorization within the bounds of the material and perceiving/acting human body.3. The paper is based on some general theoretical orientations which may be summarized as the following:– material positivism: within this orientation, the subject matter of research is the universal occurrence of embodiment/entitiation and its consequences, dialectical constructivism: within this orientation, a human agent as an embodied entity/organism is assumed to be involved in a continuous process of constructing and changing images.

Inégalités sociales et enjeux liés à la santé des aînés francophones en situation minoritaire : le cas de l’Atlantique et de l’Acadie des Maritimes
Authors: Simard Majella , Bouchard Louise
Published: December 2020

Le vieillissement démographique soulève des enjeux fondamentaux dans la réponse des acteurs sociaux aux besoins manifestés par les aînés sur le plan de la santé. L’objectif de cette contribution est double. Il consiste, d’une part, à identifier les principaux enjeux auxquels sont confrontés les aînés francophones en situation minoritaire sur le plan de la santé et, d’autre part, à examiner la situation des inégalités sociales et les conditions de vie qui en découlent comme déterminant de la santé, de la qualité et de l’accès aux services dans une perspective de développement territorial. Les résultats de notre analyse révèlent que le rapport minoritaire/ majoritaire traduit une inégalité sociale qui, couplée à d’autres déterminants sociaux, contribue de facto à la formation de disparités sur le plan de la santé, d’où la nécessité de mettre en oeuvre une politique à l’endroit des aînés vivant en milieu minoritaire francophone destinée à réduire de tels écarts.
The Impossible Embrace
Authors: Gomes Juliano
Published: December 2020

In the twentieth century, the Black Brazilian filmmakers who managed to accumulate a substantial body of work were few and far between, with a striking number of Black directors succeeding in making only one or a handful of films. Juliano Gomes examines how this landscape has changed in recent years, prompted by a new generation of film school graduates and reflected in landmark events such as the “Soul in the Eye” program at the International Film Festival Rotterdam in 2018, in which at least a quarter of the program’s films were made by students. His article focuses on two films representative of these changes: Ilha (2018), whose codirectors Ary Rosa and Glenda Nicácio met in the cinema course at the Federal University of Recôncavo da Bahia, and Travessia (2017), an award-winning student film by Safira Moreira.

A MATHEMATICAL MODEL FOR DYNAMIC PROJECT SCHEDULING PROBLEM AND REACTIVE SCHEDULING IMPLEMENTATION
Authors: RUHLUSARAÇ Murat , ÇALIŞKAN Filiz
Published: December 2020

In today's real-life implementations, projects are executed under uncertainty in a dynamic environment. In addition to resource constraints, the baseline schedule is affected due to the unpredictability of the dynamic environment. Uncertainty-based dynamic events experienced during project execution may change the baseline schedule partially or substantially and require projects' rescheduling. In this study, a mixed-integer linear programming model is proposed for the dynamic resource-constrained project scheduling problem. Three dynamic situation scenarios are solved with the proposed model, including machine breakdown, worker sickness, and electricity power cut. Finally, generated reactive schedules are completed later than the baseline schedule.

Quantum chemical modeling of orthophosphoric acid adsorption sites on the hydrated surface of anatase was performed by the method of density functional theory (exchange-correlation functional PBE0, basis set 6-31 G(d,p)). The influence of the aqueous medium was taken into account within the framework of the continual solvent model. The work uses a cluster approach. The anatase surface is simulated by a neutral Ti(OH)4(H2O)2 cluster. The results of analysis of the geometry and energy characteristics of all the calculated complexes show that the highest interaction energy is inherent to the intermolecular complex of orthophosphoric acid and hydrated surface of anatase, where the oxygen atom of the phosphoryl group (О=Р≡) forms a hydrogen bond with a hydrogen atom of the coordinated water molecule of Ti(OH)4(H2O)2 cluster and two hydrogen atoms of the hydroxyl groups of the orthophosphoric acid molecule form two hydrogen bonds with two oxygen atoms of the titanol groups. The formation energy effect of this complex is -134.0 kJ/mol. The formation energy effect of the complex with separated charges by the proton transfer from the molecule H3PO4 to the Ti(OH)4(H2O)2 cluster with the formation of dihydrogen phosphate anion and the protonated form of the titanol group (º) is -131.1 kJ/mol, so indicating less thermodynamic probability of such intermolecular interaction. The smallest thermodynamic probability (-123.9 kJ/mol) of complexation between orthophosphoric acid and hydrated anatase surface where a water molecule moves from the coordination sphere of the titanium atom. The calculation results indicate a possible adsorption of the H3PO4 molecule in an aqueous solution on the hydrated anatase surface. Taking into account the effect of the solvent within the polarization continuum insignificantly changes the adsorption energy, which is -44.5 kJ/mol; for vacuum conditions this value is -49.0 kJ/mol.

The aim of the work was to synthesize nanocomposites based on pyrogenic silica and zinc phosphate by a simple method without using a large amount of solvent and to study the characteristics and properties of the obtained materials. The dual systems of zinc phosphate/pyrogenic silica with the different ratio of components were synthesized via mechanical grinding in a porcelain drum ball mill of fumed silica (Orysyl A-380), zinc acetate (Zn(CH3COO)2·2H2O) and phosphoric acid with distilled water, followed by air-drying in an oven at 125 °C (2 h) and calcination in a muffle oven at 450 °C for 2 h. The zinc phosphate content was 0.1, 0.2, and 0.3 mmol per 1 g of SiO2. The control sample (ZP-K) was synthesized by thermal treatment of the precipitate, formed after mixing on a magnetic stirrer an aqueous solution of zinc acetate with the addition dropwise of phosphoric acid, without the use of SiO2. X-ray diffraction studies of the nanocomposites confirmed the formation of the crystalline phase of Zn3(PO4)2·4H2O (orthorhombic modification) both in the silica-containing and control ZP-K samples after air drying at 125 °C, while heat treatment at 450 °C leaded to the formation of the anhydrous monoclinic Zn3(PO4)2 phase. The content of the zinc phosphate in the dual composites was 0.1, 0.2, and 0.3 mmol per 1 g of SiO2. The IR spectra of the nanocomposites indicated the presence of absorption bands in the range of 3760-3600 cm-1, which were attributed to the unequal structural ‒OH groups of silicon and phosphorus atoms. It was found that the presence of zinc phosphate on the SiO2 surface does not cause the chemical interaction with silica during heat treatment of composites in air even at 900-1000 °C. It was shown that the ability of Zn3(PO4)2/SiO2 composites to adsorb water vapor decreases with increasing amount of modifying compound. The effect of the obtained phosphorus-containing nanocomposite on the thermal stability of an alkyd polymer matrix was considered.

Pobreza energética y exclusión en Argentina: mercados rurales dispersos y el programa PERMER
Authors: Ibañez Martín Maria Maria , Guzowski Carina , Maidana Florencia
Published: December 2020

En este artículo se analiza la relación entre energía, pobreza y exclusión social. Bajo este marco conceptual, se evalúa a partir de la revisión de antecedentes y resultados la situación de los mercados rurales dispersos en Argentina y el Programa de Energías Renovables en Mercados Rurales (PERMER) como una política inclusiva y paliativa de la pobreza energética. Se concluye que el programa ha generado un avance en el acceso de poblaciones tradicionalmente excluidas pero que sus resultados redundan en electrificación rural, con limitaciones en su incidencia en la inclusión y el desarrollo de capacidades de la población objetivo.
Representaciones discursivas de lo indígena en Costa Rica: un análisis a través de la red social Facebook
Authors: González Campos Guillermo
Published: December 2020

Introducción

Este artículo lleva a cabo una discusión crítica de los principales núcleos temáticos que gobiernan la producción del sentido en mensajes generados por la población costarricense no indígena en la red social Facebook con respecto a los pueblos indígenas del país.

Objetivo

El objetivo es identificar y analizar los discursos dominantes que, en la actualidad, gobiernan lo dicho sobre la población indígena en Costa Rica.

Método

Para tal efecto, y por medio de las técnicas propias de Corpus-assisted discourse studies, se recopilaron y analizaron comentarios hechos por personas a noticias que tratan asuntos indígenas.

Resultados

El análisis revela que el discurso sobre lo indígena en Costa Rica está determinado por cuatro núcleos de generación del sentido que se consideran perjudiciales para la representación social de este tipo de poblaciones.

Conclusión

Puede concluirse que, en efecto, hay una integración a nivel del discurso de lo indígena dentro del imaginario de identidad costarricense. Pero esta imagen de lo indígena es la asimilación de un discurso creado desde la alteridad y, por lo tanto, guarda las herencias simbólicas de la ideología colonizadora que la creó.
Reconocimiento y racionalidad en Ética y diálogo, de Albrecht Wellmer
Authors: Abril Francisco Manuel
Published: December 2020

Introducción

La temática del presente artículo refiere al vínculo que establece Albrecht Wellmer en su libro Ética y diálogo (1986), entre reconocimiento y racionalidad o facultad de juzgar. A modo de introducción, consideramos que la caracterización hecha por el autor con respecto al vínculo entre estos dos conceptos es de gran importancia ya que, una de las dificultades más significativas de la teoría crítica contemporánea, no se ha podido erigir –o por lo menos no se ha hecho de manera satisfactoria– un puente argumentativo entre la noción de racionalidad comunicativa (Habermas) y la de reconocimiento (Honneth).

Objetivo

Nuestro objetivo principal es precisar cómo entiende Wellmer el reconocimiento y cuál es la relación que establece entre este y la facultad de juzgar.

Método

Para responder a la pregunta, expondremos de forma sucinta, en la primera parte del artículo, algunas de las tesis centrales que recorren el libro aludido. Esto nos permitirá aproximarnos al punto nodal de nuestra exposición, en el cual explicaremos, utilizando la metodología de la reconstrucción conceptual, las distintas acepciones del concepto de reconocimiento y sus vínculos con la facultad de juzgar.

Resultados y conclusión

Si bien los resultados de la exposición en este punto no son definitorios, llegamos a la conclusión de que habilitan una línea prometedora para futuras investigaciones.
