Proteinase 3 (PR3) is the major autoantigen of antineutrophil cytoplasmic antibodies in Wegener's granulomatosis. Previously, it was demonstrated that PR3 induces apoptosis of human endothelial cells and that PR3 contributes to endothelial cell activation by enhancing interleukin-8 production. The present study demonstrates that PR3 binds specifically to human umbilical vein endothelial cells (HUVEC). Digoxigenin (DIG)-labeled PR3 bound readily to HUVEC cultured on coverslips. By fluorescence-activated cell sorter analysis, a homogeneous binding of PR3 to HUVEC, using either DIG-labeled or unlabeled PR3, was observed. No detectable membrane expression of PR3 was observed after either tumor necrosis factor-α stimulation or in nonstimulated HUVEC. The binding of PR3-DIG to HUVEC was dose-dependent and was inhibited by unlabeled PR3. Scatchard analysis revealed 2000 binding sites per cell, with a K
d of 0.1 μM. Affinity precipitation of biotin-labeled HUVEC membrane proteins with protein G-Sepharose bearing PR3 resulted in specific precipitation of a membrane molecule with a molecular weight of 111 kD under nonreducing conditions and 52 and 63 kD under reducing conditions. It is hypothesized that PR3, either released systemically or locally at inflammatory sites following activation of primed polymorphonuclear neutrophils, may lead to endothelial cell injury and activation of endothelial cells.

Published: April 2021

Tubulointerstitial nephritis antigen (TIN-Ag) is a recently described basement membrane glycoprotein reactive with autoantibodies in some forms of immunologically mediated human tubulointerstitial nephritis. This report presents the complete cDNA and predicted amino acid sequences of two human TIN-Ag mRNA species referred to as TIN1 and TIN2. Translation through the open reading frames of these clones indicates the presence of a signal peptide and putative prepropeptide. TIN1 additionally contains a characteristic laminin-like epidermal growth factor (EGF) motif and significant homology within the carboxy terminus with the cysteine proteinase family of enzymes. The EGF motif bears important similarities in the positions of cysteines with two motifs in the propeptide of von Willebrand factor. The EGF motif and part of the region that is homologous with the cysteine proteinase family are removed from the TIN2 cDNA. However, the rest of the sequence is identical in these two forms, indicating an alternatively spliced TIN-Ag mRNA product. Both forms contain putative calcium-binding sites. Secondary structure predictions strongly suggest differences between TIN1 and TIN2 leading to the hypothesis that these two forms of TIN-Ag may exhibit differences in their function. Expression studies with appropriate probes demonstrate expression mainly in the kidney and in the intestinal epithelium and lack of expression in other tissues. In the kidney, both TIN1 and TIN2 transcripts are detected, however, TIN1 appears to be the predominant form.
The indigenisation of customary law: Creating an indigenous legal pluralism within the South African dispensation: possible or not?
Authors: Morudu Ntebo L , Maimela Charles
Published: April 2021

The article examines the possibility of creating an indigenous legal pluralism within the South African context. Due to the historical and current marginalisation of customary law, can customary law be developed, reformed and codified? Furthermore, can the legal regimes and human rights of indigenous people of South Africa be ascertained? The article renegades the historical marginalisation of customary law due to colonialism and apartheid; where indigenous people's legal regimes were placed subordinate to common law. The article further implores the current status of indigenous law nationally and internationally. The article seeks to advance the argument based on legislative and judicial analysis, that customary law is still marginalised under the current constitutional dispensation. The international call and new recognition of customary law are commendable; the article seeks to review whether South Africa is keeping up or not to the international directives embedded within declarations and conventions they are a signatory to. The article will further comparatively analyse foreign countries that have managed to do what South Africa is struggling to achieve with regard to the recognition, development, application, and reform of customary law.

Authors: Zlatar Gamberožić Jelena , Svirčić Gotovac Anđelina
Published: April 2021

Socioprostorne transformacije u Hrvatskoj obuhvaćaju gradove i sela, kako na kopnu tako i na otocima. Vođene su interesima različitih društvenih aktera pri čemu prostor intervencije doživljava različite promjene kako u svojoj socijalnoj strukturi tako i u okolnom prostoru. Na otocima koji su danas izloženi negativnim demografskim procesima depopulacije i gubitka stanovništva, dodatno je otežano pokrenuti razvoj ili omogućiti pozitivne promjene. U tome se ističu upravo najmanji otoci i manja naselja na njima kao što je primjer naselja Povlja na Braču. U radu će se prikazati studija slučaja kao komparativna longitudinalna analiza ovog mjesta i promjene koje su vidljive u istraživanjima provedenima u razmaku od deset godina (2009. i 2019. ). Cilj je istraživanja usporediti jesu li se potencijalni turistički scenariji razvoja za Povlja iz 2009. (masovni turizam, održivi turizam i stagnacija) promijenili u ovom vremenskom razdoblju s obzirom na socijalnu i ekonomsku situaciju. Metodom polustrukturiranih intervjua sa stalnim i privremenim (sezonskim) stanovnicima Povalja istražilo se promišljanje stanovnika o trenutnom i potencijalnom turističkom razvoju mjesta, te koliko se istraživanje iz 2009. može usporediti s rezultatima istraživanja iz 2019. Istraživanje iz 2019. pokazalo je da mjesto nije napredovalo ni u turističkom ni i ekonomskom smislu, i da je od ponuđenih scenarija najprisutniji scenarij stagnacije koji prelazi i u nazadovanje.

En las heces de Didelphis marsupialis se detectaron huevos Tipo Strongylida, Ascaroidea, Spiruroidea y Trichuroidea y en las de las ratas, se observaron huevos Tipo Strongylida, Ascaroidea e Hymenolepididae. Conclusiones. Las zarigüeyas (D. marsupialis) y las ratas (R. rattus) del área metropolitana de Bucaramanga parecen estar parasitadas por una amplia variedad de helmintos en su sistema digestivo, a juzgar por los hallazgos de varios géneros de nematodos, cestodos y trematodos, solamente con haber procesado dos ejemplares de cada especie de mamífero. Los autores recomiendan adelantar estudios similares en la región, con un mayor número de animales y examinando, además del tracto digestivo, órganos como el corazón y la vesícula biliar.
Colombian vs. American corn: Quality, chemical composition, mycotoxin content and metabolizable energy
Authors: Aguillón-Páez Yandy J , Betancourt Liliana , Díaz Gonzalo J
Published: April 2021

Background: Corn is, quantitatively, one of the most important world crops (ranking second only after wheat) and a key ingredient in animal feeds. Objective: to assess and compare corn quality, mycotoxin content, chemical composition and apparent metabolizable energy (AME) of domestic and imported corn. Methods: Grain quality (USDA grading system) was determined in 30 samples of domestic and 21 samples of imported corn. From each origin, 15 samples were subjected to proximal analysis and 10 were used to determine fatty acid composition. Mycotoxin analysis was conducted on 30 samples of domestic and 23 of imported corn. Results: six of the 30 domestic samples corresponded to US1 grade (highest quality) vs. none of the imported. In the “sample grade” category (lowest quality), 10 and 6 samples corresponded to imported and domestic corn, respectively. Soybeans were found as contaminant in 15 of the 21 imported corn samples. Aspergillus spp. mycotoxins such as ochratoxin A were not detected, and aflatoxins were found in only a few samples at very low levels. Fusariotoxins such as deoxynivalenol and zearalenone were found in 61 and 43% of imported samples, respectively, but in none of the domestic samples. Domestic corn had lower carbohydrate content compared with imported corn (85.4 vs. 86.7%), but higher crude fat (3.8 vs. 3.1%). The AME values for domestic and imported corn were 3,697 and 3,378 kcal/kg, respectively. The fatty acid profiles from both corn types were similar. Conclusion: This study found significant differences between locally-grown and imported corn, particularly in terms of crude fat, AME content, fusariotoxins, and contaminant seeds (soybeans). These findings suggest that locally-grown corn might have nutritional and toxicological advantages over corn imported from the United States.
Potential ecological risk index for metals in a grazing area, Guasca, Cundinamarca
Authors: Barriga-Vélez Maira Alejandra , Ramírez-Vargas Laura Carolina , López Barrera Ellie Anne , Peña-Rincón Carlos Arturo
Published: April 2021

The presence of metals in soils used for primary economic activities can negatively impact the environment and public health. This research identified soil contamination by heavy metals (Lead, Copper, Zinc, and Manganese) by examining physical and chemical properties (Phosphorus, Potassium, organic carbon, cation exchange capacity, pH, texture, and bulk density) of the area during the dry and rainy seasons of 2017. Composite samplings of soil were carried out in both seasons, in order to obtain a representative value of the soil in certified laboratories. Thereafter, through interpolation by means of the Kriging method, a spatial scale of metal concentrations was conducted. This led to the conclusion that the study area has an acceptable environmental quality (5.8-6.9) for its current use of grazing. Likewise, the area presents a medium level (75.37), pursuant to the Potential Ecological Risk Index (RI) for the dry season, and a very high risk (195.04) during the rainy season. These estimates are directly related to lead concentrations, introduced to the soil of the area by human development activities and by contributions of parent material to the soil surface layers, through natural processes of weathering.
Fragmentation model for tensile behavior of intermingled hybrid composites and optimal mixing ratio
Authors: Vanegas- Jaramillo Juan David , Cruz-Riaño Luis Javier , Patiño-Arcila Iván David
Published: April 2021

A numerical fragmentation model is proposed to predict the mechanical response of intermingled, unidirectional hybrid composites under tensile loads. The model is based on a previously developed for unidirectional composites considering the critical number of fiber breaks and the correction of the fiber-matrix interfacial strength. Hybrids comprising two reinforcements are considered, and the energetic contribution of reinforcements is evaluated during the damage process. Additionally, the pseudo-ductile strain, yield strength, and the level of degradation of each reinforcement are estimated. The present model is compared with a progressive failure model and micromechanical finite element simulations, obtaining some similarities in the stress-strain behavior.  Results show that both low elongation and high elongation fiber sub-composite experience a linear tensile response where fibers remain intact (IF), and fragmentation (FM) where breaking appears. The sliding/separation phenomenon (SS) occurs in one of the sub-composites when crack saturation is obtained, and failure occurs when the other one undergoes the crack saturation. Results also show that the IF, FM, and SS phenomena are conditioned by the fiber mixing ratio, α. The model allows estimating the optimal value of α for which the highest pseudo-ductile strain and hybrid effect are reached.
Evaluation of different methodologies for the design of the wellfield in shallow geothermal systems

Published: April 2021

Low enthalpy geothermal resources play an essential role in climate change mitigation. When ensuring the correct future operation of ground-source heat pump systems, an accurate design is mandatory. In this sense, different methodologies can be implemented. Although using sophisticated software constitutes the most optimal solution, its implementation is sometimes inviable in certain projects (the increase of the initial investment required is not justified in small plants). This work is focused on evaluating and comparing procedures used in the design of shallow geothermal systems. Thus, the research includes a simple method based on manual calculations, the Climasoft free application, Earth Energy Designer (EED) software, and the new geothermal tool GES-CAL developed by researchers from the TIDOP Research Group (University of Salamanca). The objective is to evaluate this new software and compare the results of all the detailed methodologies. This comparison derives from applying these tools in the calculation of the same case study (a single-family house placed in Ávila, Spain). Results show that the easiest methods involve oversized well-field schemas that also mean higher initial investments. Regarding GES-CAL, it is considered an accurate and valid alternative for the design of all heat exchanger configurations, especially for those installations placed in the region of Ávila. However, EED is recommended to calculate high-power geothermal systems that require an exhaustive analysis of the ground and the heat carrier fluid behaviour.

Published: April 2021

Objective: Ionizing radiation is widely used in the hospital for diagnostic and therapeutic procedures to patients and its usage increasing day by day. The aim of the study is to monitor the real-time radiation around the Shaheed Suhrawardy Medical College (ShSMC) hospital campus and estimation of radiation risk on public.

Method: The real-time radiation monitoring around the ShSMC hospital was performed using digital portable radiation monitoring device (DPRMD). The DPRMD meets all European CE standards and the American “FCC 15 standard”. The DPRMD was placed at 1 meter above the ground on tripod and data collection time for each monitoring point (MP) was 1 hour. Each MP was marked out using Garmin eTrex GPS device. 32 MPs were chosen for collection of the real-time radiation dose rates around the ShSMC hospital campus in October 2020.

Results: The real-time radiation dose rates around the ShSMC hospital campus were ranged from 0.37-3.39 µSv/hr with an average of 1.537 ± 0.359 µSv/hr. The annual effective dose on public were ranged from 1.326 ± 0.551 mSv to 4.902 ± 0.705 mSv with an average of 2.694 ± 0.629 mSv. The excess life-time cancer risk (ELCR) on public health was estimated based on the annual effective dose that ranged from 5.277×10ˆ-3 to 19.503×10ˆ-3 with an average value of 10.72×10ˆ-3 around the ShSMC hospital campus.

Conclusion: Real-time radiation monitoring facilitates to ensure the safety of the radiation workers and the public from undue radiation hazard. The study also gives instant information of improper operation of radiation generating equipments and improper handling of radioactive substances in the hospital.
A prospective study on the role of epidural steroidal injections in backache with radiculopathy
Authors: Gupta Akhil , Choudhary Nitin , Malik Fareed Hussain
Published: April 2021

Background: Low backache (LBA) with lumbosacral radiculopathy is the most challenging musculoskeletal problem for its therapeutic management and cause of LBA with radiculopathy is a prolapsed disc. Epidural steroidal injection (ESI) are used in the management of the patients with sub-acute or chronic LBA with radiculopathy, not responding to conservative treatment. The most common cause being, lumbar disc disease, is confirmed via magnetic resonance imaging having high sensitivity and specificity.  The aim of study was to check the efficacy of ESI in patients of sub-acute or chronic low backache with radiculopathy due to herniated disc.

Methods: The study was conducted over 200 patients reporting our OPD during Dec 2017- Feb 2018 with complaints of LBA with radiculopathy, not responding to conservative treatment. Maximum of 3 ESI were given with two weeks of interval in between. The patients were assessed using VAS scoring system.

Results: 77.5% patients got improvement in symptoms, according to the VAS scores, while 22.5% patients got very little relief or no relief at all. 53.5% patients got significant improvement with the first dose of injection itself. Patients had a good relief from radicular pain immediately; however, sense of satisfaction of well-being was only after few months.

Conclusions: Though results supported the relative benefit of epidural steroid, however conservative management should also be recommended as initial treatment. ESI procedure is effective in treating patients of sub-acute LBA with radiculopathy and is recommended before a patient is considered for surgery.
Giant hepatic capillary hemangioma, a diagnostic dilemma: case report
Authors: Dhali Arkadeep , Hazra Anirban , Roger B. Rathna , Dhali Gopal Krishna , Sarkar Avik
Published: April 2021

Hepatic Hemangiomas (HH) are benign tumors of the liver consisting of a blood-filled cavity supplied by the hepatic artery. Most of the HH are asymptomatic and are discovered incidentally during radiological imaging of various unrelated pathology. Typical capillary hemangiomas range from a few millimeters to three centimeters and are unlikely to generate any future symptomatology. However, giant liver hemangiomas (more than 10 cm) are a very rare entity and might become symptomatic, hence requiring prompt intervention. We are reporting this case to make the readers aware of the pitfalls and radiological uncertainties while interpreting vascular lesions of the liver. We reported a case of a 21-year-old female with complaint of awareness of a mass over the right upper abdomen since a period of one year which has been gradually increasing in size. On pre-operative Contrast-Enhanced Computed Tomography, features suggestive of Fibrolamellar variant of Hepatocellular Carcinoma was found which was substantiated by biochemical investigations. However, post-operative histopathological examination revealed a capillary hemangioma.
Hypertrophic cardiomyopathy mimicking inferior wall myocardial infarction
Authors: Sharma Prachi , Pradhan Akshyaya , Vishwakarma Pravesh
Published: April 2021

Electrocardiogram is most often the first-hand diagnostic tool with a cardiologist. Promptly identifying life threatening arrhythmias and myocardial infarction with ECG saves many lives. Quite often the electrocardiogram may have dubious findings and further testing helps arriving at the right diagnosis. Herein, we present a case of hypertrophic cardiomyopathy where the ECG mimicked inferior wall myocardial infarction along with a raised high sensitive Troponin T (hsTnT). A coronary angiogram failed to reveal any acute or chronic obstructive lesion in the coronary arteries. We discussed the varied ECG patterns in hypertrophic cardiomyopathy and causes of troponin elevation apart from myocardial infarction. We also discussed other causes of ‘pseudo-infarct’ pattern on ECG. This provides insight into a more comprehensive approach in management of each patient.

Authors: Oliveira Flora Palmari Audi , Souza Vitória Melina Faquini de , Bueno Maura Lima Pereira , Roversi Fernanda Marconi
Published: April 2021

Background: Multiple myeloma is characterized by abnormal plasmocytes proliferation in the bone marrow, resulting in an immunoglobulin oversecretion, which can cause bone pain, anemia, kidney dysfunction, and infections. The present study evaluates prognostic factors and the bone involvement in patients who had a confirmed diagnosis of MM.

Methods: A retrospective study was conducted in hospital universitário São Francisco of Bragança Paulista. Patient demographic data, laboratory parameters and treatment received were recorded. We also analyzed the variables related to diagnosis and the development of bone lesions in MM patients.

Results: A total of 42 patients had a confirmed diagnosis of MM, out of which most (54.76%) were older than 65. Most patients (45.24%) had beta-2-microglobulin values greater than 5.5 mcg/dl, indicating an advanced stage of the disease and consequently a less favorable prognosis. The main clinical manifestation observed was anemia in 61.90% (26/42) and bone lesions 59.52% (25/42). The analysis of imaging exams showed that most patients presented bone alterations, such as osteopenia, lytic lesions and fractures. Interestingly, 11.90% patients were submitted to autologous bone marrow transplantation with further remission of the disease. Bone marrow transplantation increases overall survival and disease-free survival when compared to conventional treatment.

Conclusions: Since MM prognostic factors are numerous and, therefore, the understanding and analysis of the clinical and laboratory features of MM can contribute to an early diagnosis of patients, a targeted therapeutic approach and better outcomes.
Thermal Study of Three-Phase Squirrel Cage Induction Motor with the Open-Phase Fault Operation Using a Lumped Parameter Network (LPTN)
Authors: Atig Mahdi , Bouheraoua Mustapha , Khaldi Rabah
Published: April 2021

The aim of this paper is to estimate the induction motor temperature at both steady and transient thermal states under healthy and faulty conditions. The distribution of the temperature in the motor is calculated using thermal models based on the 2D Lumped Parameter Thermal Network (LPTN). The thermal model takes into account the heat sources, convection heat transfer and the thermal resistances in the motor. The heat flow generated by the conduction and convection in a three-phase squirrel cage induction motor is discussed. The developed model is used to study the motor thermal behavior during the opening phase situation. The results obtained by the model developed are validated by experimental tests. The tested machine is a standard three-phase, 4-pole, 2.2 kW, 380 V squirrel cage induction motor of Totally Enclosed Fan Cooled “TEFC” design manufactured in Algeria by Electro-Industries company. The simulated temperatures so obtained are in good agreement with the measured ones, and the 2D Lumped Parameter Thermal Network study seems to be appropriate to characterize the heating of the active parts of the machine under different operating conditions.
Attitude of Russian teachers to cultural diversity in difficult pedagogical situations: Experience of qualitative analysis
Authors:   Moscow State University of Psychology & Education, Khukhlaev Oleg E. , Tkachenko Natalya V. ,   Moscow State University of Psychology & Education
Published: April 2021

Student-related cultural diversity is a phenomenon that characterizes most Russian schools. Intercultural interaction between teachers and students is discussed in the article from the perspective of the model called “Diversity in Organizations: Perception and Approaches” developed by M. Tatar and G. Gorenchik. The purpose of the study was to investigate the content of the ideas of Russian teachers about cultural diversity in the educational environment in the context of solving difficult pedagogical situations when interacting with children of migrants belonging to different cultures. The hypothesis of the study was the assumption that meaningfully different approaches to understanding cultural diversity in the educational environment constitute the interrelated integrated system of views, and their manifestation is largely related to how a teacher copes with difficult pedagogical situations when working with children belonging to other cultures and their parents. To achieve this goal, we chose the qualitative research method, which allows us to focus on the analysis of the respondent’s personal experience. The study was carried out in the format of in-depth interviews involving 6 teachers, who were females, aged 34 to 55 years, living in Moscow, Voronezh region and the Komi Republic. The interview transcripts were analysed using a phenomenological approach. It was established that Russian teachers used all four approaches to assessing cultural differences: Problem, Challenge, Resource and Indifference. It was shown that within different contexts, in different difficult situations, the same teacher could demonstrate a different attitude towards cultural characteristics of migrants’ children belonging to a foreign culture. It was established that cultural differences were the focus of the teacher’s attention in the situation of their problematization, when they created difficult pedagogical situations in combination with bright external markers of the student’s cultural affiliation. The obtained results allow for more effective development of teachers’ professional practice and promote the perception of cultural diversity as a Challenge and/or Resource.
Educational situation simulation in the co-being environment
Authors:   Institute for Strategy of Education Development of the Russian Academy of Education, Shustova Inna Yu.
Published: April 2021

The relevance of the problem stated in this article is conditioned by the important socio-cultural goal, that modern Russian school faces, of becoming the basis for the spiritual and moral development and education of an individual. Problem solving leads to the need for searching for resources that activate the educational process, which leads it to the environment of pupils’ values and meanings. The purpose of the study is to reveal the co-being approach to simulation and organization of pedagogical situations in working with pupils. Co-being is considered through the process of value-semantic interaction of a teacher with children. The interaction environment is a circle that includes the person and other people, their integration with others; a set of events that are significant for the individual; the present reality. The hypothesis of the study is that upbringing requires situations of interaction with pupils who form a co-being child-adult integration. We show that educational situation simulation in the space of co-being involves the use of specific situations arising in upbringing, while a teacher and pupils interact, which are significant moments in the lives of the latter and stimulate their self-determination and self-realization. We present a possible typology of such situations: living situation, communication situation, inter-age communication situation, a situation that sets meaningful experience and its interpretation, a situation of difficulty and uncertainty.
Ethical and psychological factors of social activity of modern young people
Authors:   Saratov State University, Bocharova Elena E.
Published: April 2021

The purpose of the study presented in the article is an empirical study of the relationship between characteristics of moral self-determination and various forms of social activity of young people. The study involves students (N = 236): high school students (n = 118) and university students (n = 118) of Saratov and Saratov Oblast (Russia) aged from 17 to 19 years. We use the following techniques as methodological tools: a questionnaire aimed at registering various forms of social activity and the degree of its manifestation (R. M. Shamionov, I. V. Arendachuk, E. E. Bocharova and others) and the “Moral self-determination of an individual” technique (A. E. Vorobyova, A. B. Kupreychenko) to record the characteristics of moral self-determination. The hypothesis of the study is an assumption regarding presence of multidirectional relationships between the measures of manifestation of the moral self-determination parameters and self-assessments of various forms of social activity. Recognition of the importance of morality and ethics is a positive predictor of altruistic and educational and developmental forms of activity of schoolchildren and a negative predictor in the case of actualization of the socio-economic activity of university students. We have recorded the tendency of positive dynamics in the manifestation frequency of relationships between the parameters of moral self-determination and forms of social activity: from the minimum number among schoolchildren to its increase among university students. The materials presented can be implemented in the practice of advisory services of educational institutions and in the organization of socially useful activities of young people.

Published: April 2021

The study analyzes the problem of the influence of prompts on the achievement of creative problem solution and conditions under which it is effective. The relevance of the topic is determined by the context of the determinants and factors that define success of solving creative problems. From the standpoint of the problem situations theory, we revealed conditions for positive influence of direct and indirect prompts in solving problems of different content. Various characteristics of the subject of thinking are considered as conditions: from the perspective of the intellectual sphere, it is general intelligence and depth of analysis, while from the perspective of motivational sphere, it is manifestation of situational cognitive need, from the perspective of personality sphere, these are characteristics associated with the task content. The purpose is to study conditions for effectiveness of prompts in solving problem situations of different content. We propose the hypotheses stating that conditions for effectiveness of prompts are: manifestation of interest in solving challenging problems of any content; intellectual characteristics when solving scientific problems; personal characteristics when solving artistic problems. The sample consisted of 39 people: 27 students of the 1st and 2nd year of the Faculty of Psychology from Moscow State University and 12 specialists in the problem field. It also involved representatives of other professional fields, who carried out expert assessment of the effectiveness of prompts. The participants of the study solved 8 challenging problems of scientific and artistic content with prompts, 216 solution protocols were analysed. We used the following techniques: “Progressive matrices of Raven” and “Complex analogies” for diagnostics of intellectual features; the technique of self-actualization of personality for personality sphere diagnostics; subjective scaling for diagnostics of the assessment of interest manifestation. It is shown that subjective conditions for the effectiveness of the prompt are different depending on the content of the problem and on its difficulty for the subject. For most problematic situations of scientific content, a direct prompt turns out to be significant, and the condition for its effectiveness is the manifestation of the subject’s interest in the solution. For difficult problematic situations of artistic content, the depth of analysis, general intelligence and personal characteristics of the subject, which are associated with understanding the content of the problem, are the conditions for the effectiveness of indirect prompts.
Mesenteric panniculitis: can venous anatomy and malignancy be a trigger cause?
Authors: GÜLTEKİN Mehmet Ali
Published: April 2021

Objectives: To investigate whether portal vein (PV), splenic vein (SV), superior mesenteric vein (SMV) diameters and portomesenteric angle (PMA) may play a role in the etiology of mesenteric panniculitis (MP). To investigate relationship between MP and malignancy.
Methods: We included 70 patients with MP and 70 patients age, gender, sagittal abdominal diameter randomly matched control group, retrospectively.
Results: We found slightly higher PV and SMV diameter and slightly lower SV diameter in MP patients compared with control group. But these results were not statistically significant (p1 = 0.321 and p2 = 0.147, p1 = 0.540 and p2 = 0.185, p1= 0.216 and p2 = 0.617, for two observers respectively). We found higher PMA in MP patients compared with control group but this difference is not statistically significant (p1 = 0.252 and p2 = 0.366, for two observers). Twenty three (32.9%) of 70 patients diagnosed MP have underlying malignancy while 17 (24.3%) of 70 control subject were coexisted malignancy. But this difference is not statistically significant (p = 0.262). Interobserver agreement was excellent in terms of SMV and SV diameters and PMA measurements (ICC were 0.927, 0.911 and 0.965 respectively), good for PV diameters (ICC was 0.884).
Conclusions: Study results show that MP is not associated with PV, SMV and PMA. Contrary to some studies, there is no relationship between MP and malignancy.

This essay engages the border-crossing poetics of transnational migration through an engagement with Valeria Luiselli’s fictional depictions of migrant children in her novel Lost Children Archive. Engaging the migrating and intertextual forum of children’s witness and memory in the novel, I follow Luiselli’s moving depiction of child migrants as wholly undocumented and lost people outside the adult world of articulation. I argue that Luiselli’s novel documentation conjures up historical, contemporary, and autobiographical memories of migrant and displaced children comprising the colonial story of modernism. I consider children’s articulations, construction and witness of migration through my readings of the stories of migrating childhood delivered by Luiselli’s fictional depiction. I find, Luiselli’s moving rendition of children’s migration presents new challenges to educational and popular discourses of childhood, migration, and the responsibilities of the adult communities.

Buscaremos, neste ensaio, apresentar propostas teóricas possíveis para pensar uma situação inusitada e particular em que se encontram muitos indianos atualmente. Partiremos de experiências concretas, frutos de um estranhamento que beira a perplexidade, para mostrar a dificuldade real em compreender o que se entende por modernidade na Índia. Seguimos com uma revisão bibliográfica de autores os quais acreditamos que estão na busca por compreender uma realidade que necessita de pressupostos teóricos cujo escopo seja capaz de abarcar uma cultura milenar forte e persistente em contato direto com a globalização. Para isso, traremos a discussão textos de Homi Bhabha e parte da obra de Salman Rushdie.
Cultural nationalism, interdisciplinary methodological proposals
Authors: Giori Pablo
Published: April 2021

Vivimos el siglo del nacionalismo y, paradójicamente, el del individualismo. El pensamiento sobre la colectividad y sobre el sujeto invade las reflexiones de las ciencias sociales de los últimos 100 años, principalmente luego del boom del psicoanálisis y del marxismo. Metodológicamente, la necesidad de que las ciencias sociales sean consideradas ciencias, en comparación con las ciencias naturales y su Método, ha generado una imposibilidad de pensar la realidad por fuera de sus aspectos racionales. La propuesta de

este artículo es la de pensar el nacionalismo cívico, desde las experiencias de Cataluña y del Quebec, para hacer una propuesta teórico-metodológica que, en el cruce entre sociología, antropología, ciencias políticas e historia, nos permita pensar este fenómeno tan actual de una manera más profunda. El nacionalismo no es únicamente desarrollado por las instituciones políticas, sino que es, principalmente, una experiencia cotidiana, una forma de hacer y de pensar nuestra identidad: la nación se piensa, pero principalmente se vive, se baila, se siente.
O ocaso do racionalismo e a perspectiva erótica no empreendimento etnográfico

As vozes que questionam o positivismo e a inabilidade de seus instrumentos teórico-analíticos em conceitualizar o dinamismo do mundo contemporâneo vem de distintos lugares com agendas diversas. Um compromisso ético, que reconheça o caráter ideológico e subjetivo da empresa científica e acredite na negociação dos limites da participação na interação e uma agenda política, responsável pelos efeitos da pesquisa, comprometida com a mudança e com a desnormativização da sociedade estão entre essas vozes de mudança e entre as perspectivas discutidas no texto. Advogando uma metodologia híbrida, indisciplinar que respeita as sensações e sentimentos como legítimos produtores de saber e que aposta no desejo e no erotismo como fonte de inspiração, é discutida a necessidade de desaprender enferrujados paradigmas para que as teorizações sociais não sejam anacrônicas ao seu tempo. Será defendido o reconhecimento da subjetividade, do corpo e dos desejos do investigador como inflexões de produção de conhecimento.

A greve das universidades federais e os desafios de mobilização na pós-graduação
Authors: Campos João Pedro Lima
Published: April 2021

Neste artigo apresento um relato crítico sobre a greve de estudantes, docentes e trabalhadores da Universidade Federal Fluminense (UFF) no ano de 2015 a partir da discussão sobre os desafios de mobilização na pós-graduação. Essa greve aconteceu no marco dos primeiros cortes orçamentários realizados ainda no início do segundo mandato da presidenta Dilma Rousseff, que afetou o equilíbrio financeiro das reitorias, resultando em atraso no pagamento de salários e bolsas. Para entendermos através de que mecanismos a redução do repasse impacta a universidade federal, analisamos a relação existente entre a greve de 2015 e o processo de desmonte do programa de Reestruturação e Expansão das Universidades Federais (REUNI), razão medular para a organização da luta política relatada. Apresento também as lições aprendidas em um cenário de severos ataques à universidade pública a fim de apontar soluções para o problema da organização dos alunos de pós-graduação, que historicamente não conseguem se articular em defesa dos próprios interesses.
Sobre greve, liberdade e rinocerontes
Authors: Sester Eros , Antunes Sara Vieira
Published: April 2021

Partindo do contexto da greve de 2016 na Unicamp, marcado por um ambiente politicamente frágil e acirramento entre diferentes atores/atrizes no embate institucional e civil, o presente texto propõe uma análise crítica da montagem “Canto para Rinocerontes e Homens”, encenada no referido ano pela companhia Teatro do Osso. Baseada na dramaturgia “O Rinoceronte” de Eugène Ionesco, a peça que aqui serve de emblema revela e retorce uma série de contradições explícitas e implícitas na onda de conservadorismo que tem acompanhado a crise econômica e a irresponsável e indecente gestão política institucional. Elaborada por mestres em formação durante o período da greve, a resenha é elaborada como um diálogo-debate e redigida colaborativamente em um estilo ensaístico, e reflete em sua forma a elaboração de um espaço onde as normas acadêmicas de produção do conhecimento científico puderam ser colocadas em perspectiva. Esperamos, com o texto que segue, provocar reflexões nos/as leitores/as atinentes aos próprios valores e convicções que tem governado nossas concepções acerca do humano e dos mundos que queremos.

No dia 12 de maio de 2016, o Brasil acordou com a ressaca da iminência da concretização do afastamento da presidenta eleita Dilma Rousseff, a partir da abertura de um processo de impeachment, que em poucos dias se materializou como um golpe de Estado parlamentar-judicial em processo. O presidente interino Michel Temer deu início, logo na primeira semana do seu mandato, ao desmonte das políticas sociais conquistadas principalmente desde a Constituição de 1988, ao longo de quase 30 anos do curto período democrático brasileiro. Na intenção de contribuir com a agenda de pesquisa acerca das consequências do golpe em curso no país, este artigo apresenta algumas análises iniciais de um levantamento de notícias publicadas na mídia onlineno mês de maio de 2016, a respeito das primeiras medidas do governo, então, interino de Michel Temer. Em especial, buscamos analisar como diferentes veículos de comunicação virtual divulgaram as primeiras ações deste governo.
