Published: December 2020

Grafted seedlings are used not only for protection from soil-borne diseases but also to increase tolerance to abiotic stress conditions, improve fruit quality and increase nutrient uptake in the soil. In this study, it was aimed to determine the effect of different watermelon rootstocks on weight loss of watermelon fruits, which were obtained at deficit irrigation levels and they were stored under controlled conditions for different periods. For this purpose, 2 citron watermelons, 1 open bottle gourd and 1 hybrid TZ-148 which is widely used for watermelon in Turkey were used as rootstock. The "Crimson Tide" commercial cultivar was grafted onto these rootstocks and non-grafted applications were used as control lots. 5 different irrigation levels were applied according to the plant pan coefficient such as kcp1 = 1.00 (I100), kcp2 = 0.75 (I75), kcp3 = 0.50 (I50), kcp4 = 0.33 (I33) and kcp5 = 0.00 (I0) non-irrigated. According to the results, all watermelon rootstocks caused by less fruit weight loss compared to non-grafted applications and it has been demonstrated that using grafted rootstocks is an advantage in watermelons to be stored. On the other hand, TZ-148 commercial rootstock and citron melon 1 rootstock determined as the best rootstock in post-harvest storage. The I100 and I75 irrigation levels have approximately the same weight loss.

Facile One-pot Synthesis of A Novel Propargyl-Azulene Hybrid Derivative: Cycloaddition Reaction and Some Spectroscopic Properties
Authors: ERDOĞAN Musa
Published: December 2020

Guaiazulene, 1,4-dimethyl-7-isopropylazulene, is one of the non-benzenoid aromatic compounds consisting of fused of the seven- and the five-membered ring. Guaiazulene is an important natural product and having great potential due to its unique optical and electronic properties. In this study, a method for propargyl insertion into the C-4 methyl group of the guaiazulene is developed. A one-pot reaction of the guaiazulene, LDA, and propargyl bromide in THF affords the corresponding a new propargyl-azulene hybrid derivative. Additionally, Diels-Alder cycloaddition reaction between the propargyl-GA and tetraphenylcyclopentadienone was performed, and the cycloadduct was obtained with excellent yield. The structures of new compounds were elucidated on the basis of extensive spectroscopic (IR, NMR, and UV-vis) data analysis. This approach may be potentially useful for the development of the new azulene derivatives.
Effectiveness of peracetic acid and EarthTec QZ for controlling zebra and quagga mussels in drinking water treatment plants on Lake Ontario
Authors: Hurtado Alonso , Alonzo-Moya Carlos , Hofmann Ronald
Published: December 2020

Prechlorination is the most common strategy for zebra and quagga mussel control in drinking water treatment plant intakes in the Great Lakes region. Although effective and inexpensive, chlorine can form regulated disinfection byproducts. Two potential alternatives to prechlorination were evaluated for mussel control: peracetic acid (PAA) and EarthTec QZ, a copper-based product. Pilot-scale experiments were conducted to test EarthTec QZ for veliger control and to evaluate the efficiency of PAA and EarthTec QZ for adult mussel control. EarthTec QZ doses of 30, 60, and 120 μg/L as copper ions demonstrated dose-dependent veliger control at 12 °C. PAA doses of 5, 10, and 25 mg/L were effective for adult mussel control at the low water temperatures tested (4 °C). Results from this study indicate that PAA and EarthTec QZ may be an alternative to prechlorination.

Authors: Yang Jian-Bo , Gao Hui-Yu , Song Yun-Fei , Liu Yue , Wang Qi , Wang Ying , Ma Shuang-Cheng , Cheng Xian-Long , Wei Feng
Published: December 2020

Background:

The roots of Polygonum multiflorum (PM) are a well-known traditional Chinese
medicine, widely used to treat a variety of conditions in Southeast Asia, South Korea, Japan and other countries.
It is known that Polygoni Multiflori Radix Praeparata (PMRP) may enhance the efficacy and reduce the
toxicity of PM. However, reports of adverse reactions, such as hepatotoxicity, caused by PM or PMRP, have
continuously appeared around the world, which increased the known risks of the medication and gradually
gained the extensive attention of many researchers. The chemical constituents of PM that cause hepatotoxicity
have not been distinctly elucidated using the traditional phytochemical screening. Recently, with the rapid development
of metabolomics, there has been a growing need to explore the potential hepatotoxic components
and mechanisms of PM.

Methods:

The metabolites and metabolomics of PM were searched by the Web of Science, PubMed, Google
scholar and some Chinese literature databases.

Results:

A brief description of metabolites and metabolomics of PM is followed by a discussion on the metabolite-
induced toxicity in this review. More than 100 metabolites were tentatively identified and this will contribute
to further understanding of the potential hepatotoxic components of PM. Meanwhile, some toxic compounds
were identified and could be used as potential toxic markers of PM.

Conclusion:

This review mainly outlines the metabolites and metabolomics of PM that have been identified in
recent years. This study could help to clarify the potential hepatotoxic components and metabolic mechanisms
of PM and provide a scientific reference for its safe clinical use in the future.
Early Failures of Total Knee Patients with Nickel Allergies Secondary to Carbon Fiber Debris
Authors: Maale Gerhard , Mohammadi Daniel , Kennard Nicole , Srinivasaraghavan Aniruth
Published: December 2020

Aim:

Currently, there are not many studies on the long-term outcomes of the specific implants used in patients with metal hypersensitivities. The purpose of this study is to report a significant number of TKA revision failures with the CFR-PEEK prosthetic knee implant with an anatomic hinge.

Background:

Patients can experience multiple issues following a primary Total Knee Arthroplasty (TKA). A growing body of research is finding a correlation between primary TKA failure and metal hypersensitivity, most commonly with nickel and cobalt. Because of this, knee prosthetics are being made from hypoallergenic metals, such as zirconium nitride (ZrN), to minimize the number of failures due to metal allergy. Given the relatively new development of the hypoallergenic prostheses, there is sparse data about their overall success.

Objective:

The purpose of this study is to report a significant number of TKA revision failures with the CFR-PEEK prosthetic knee implant with an anatomic hinge.

Methods:

In this study, we analyzed the sequelae of 84 patients between May 2015 to June 2020 who received a total knee revision due to a failed primary TKA with metal hypersensitivity. These patients were revised with the rotating anatomic hinge knee system, which consisted of Carbon Fiber Reinforced Poly-Ether-Ether-Ketone (CFR-PEEK implant) coated with a ZrN, Zirconium, and Chrome Nitride multi-layer surface coating with 30% polyacrylonitrile fiber content. The patients requiring an additional revision operation presented with increasing pain that showed evidence of osteolysis on plain radiographs, CT imaging, positive indium labeled WBC scans and increased uptake on bone scan. Intraoperatively, an open incisional biopsy of the surgical bed was obtained, followed by radical debridement and implantation of porex knee prosthesis. In addition, intraoperative findings included black debris that grossly stained the surrounding synovial tissue black, indicative of wear and debris from carbon fiber bearings and the anatomic hinge. Histology of the intraoperative biopsy showed the accumulation of black debris in the histiocyte, fibrosis, and perivascular cuffing of lymphocytes and multinucleated giant cells stained with black debris.

Results:

Of the 84 patients, 22 failed, requiring an additional revision procedure, equating to a 26 percent failure rate of the CFR-PEEK implant, averaging 25 months to failure.

Conclusion:

This study was meant to report the extremely high failure rate of the anatomic hinge secondary to carbon fiber debris. Perhaps carbon fiber-laden implants are not as good an option for total knee revision prosthesis because of the high failure rate compared to those with polyethylene in their hinge mechanism.

Authors: Saxena Priya , Mahmood Tarique , Dixit Manish , Gambhir Sanjay , Ahsan Farogh
Published: December 2020

The development of new radiolabeled Positron emission tomography tracers has been extensively utilized to access the increasing diversity in the research process and to facilitate the development in research methodology, clinical usage of drug discovery and patient care. Recent advances in radiochemistry, as well as the latest techniques in automated radio-synthesizer, have encouraged and challenged the radiochemists to produce the routinely developed radiotracers. Various radionuclides like 18F, 11C, 15O, 13N 99mTc, 131I, 124I and 64Cu are used for incorporating into different chemical scaffolds; among them, 18F and 11C tagged radiotracers are mostly explored such as 11C-Methionine, 11C-Choline, 18F-FDG, 18F-FLT, and 18F-FES. This review is focused on the development of radiochemistry routes to synthesize different radiotracers of 11C and 18F for clinical studies.

Privacy Policy Compliance of Chronic Disease Management Apps in China: Scale Development and Content Evaluation
Authors: Ni Zhenni , Wang Yiying , Qian Yuxing
Published: December 2020

Background

With the development of mobile health (mHealth), chronic disease management apps have brought not only the possibility of reducing the burden of chronic diseases but also huge privacy risks to patients’ health data.

Objective

The purpose of the study was to analyze the extent to which chronic disease management apps in China comply with the Personal Information Security Specification (PI Specification).

Methods

The compliance of 45 popular chronic disease management apps was evaluated from the perspective of the information life cycle. To conduct a fine-grained evaluation, a scale based on the PI Specification was developed. Finally, 6 level 1 indicators, 22 level 2 indicators, and 61 level 3 indicators were defined.

Results

There were 33/45 apps (73%) with a privacy policy, and the average score of these apps was 40.4 out of 100. Items of level 1 indicators with high scores included general characteristics (mean 51.9% [SD 28.1%]), information collection and use (mean 51.1% [SD 36.7%]), and information sharing and transfer (mean 50.3% [SD 33.5%]). Information storage and protection had the lowest compliance with PI Specification (mean 29.4% [SD 32.4%]). Few personal information (PI) controllers have stated how to handle security incidents, including security incident reporting (7/33, 21%), security incident notification (10/33, 30%), and commitment to bear corresponding legal responsibility for PI security incidents (1/33, 3%). The performance of apps in the stage of information destruction (mean 31.8% [SD 40.0%]) was poor, and only 21% (7/33) apps would notify third parties to promptly delete PI after individuals cancelled their accounts. Moreover, the scoring rate for rights of PI subjects is generally low (mean 31.2% [SD 35.5%]), especially for obtaining copies of PI (15%) and responding to requests (25%).

Conclusions

Although most chronic disease management apps had a privacy policy, the total compliance rate of the policy content was low, especially in the stage of information storage and protection. Thus, the field has a long way to go with regard to compliance around personal privacy protection in China.
COVID-19 Misinformation Spread in Eight Countries: Exponential Growth Modeling Study
Authors: Nsoesie Elaine Okanyene , Cesare Nina , Müller Martin , Ozonoff Al
Published: December 2020

Background

The epidemic of misinformation about COVID-19 transmission, prevention, and treatment has been going on since the start of the pandemic. However, data on the exposure and impact of misinformation is not readily available.

Objective

We aim to characterize and compare the start, peak, and doubling time of COVID-19 misinformation topics across 8 countries using an exponential growth model usually employed to study infectious disease epidemics.

Methods

COVID-19 misinformation topics were selected from the World Health Organization Mythbusters website. Data representing exposure was obtained from the Google Trends application programming interface for 8 English-speaking countries. Exponential growth models were used in modeling trends for each country.

Results

Searches for “coronavirus AND 5G” started at different times but peaked in the same week for 6 countries. Searches for 5G also had the shortest doubling time across all misinformation topics, with the shortest time in Nigeria and South Africa (approximately 4-5 days). Searches for “coronavirus AND ginger” started at the same time (the week of January 19, 2020) for several countries, but peaks were incongruent, and searches did not always grow exponentially after the initial week. Searches for “coronavirus AND sun” had different start times across countries but peaked at the same time for multiple countries.

Conclusions

Patterns in the start, peak, and doubling time for “coronavirus AND 5G” were different from the other misinformation topics and were mostly consistent across countries assessed, which might be attributable to a lack of public understanding of 5G technology. Understanding the spread of misinformation, similarities and differences across different contexts can help in the development of appropriate interventions for limiting its impact similar to how we address infectious disease epidemics. Furthermore, the rapid proliferation of misinformation that discourages adherence to public health interventions could be predictive of future increases in disease cases.
La integración educativa universitaria en Centroamérica (1948-1975)
Authors: Sancho Domingo Carlos
Published: December 2020

Como consecuencia de la corriente de integración política y económica que a comienzos de la década de 1950 recorrió Centroamérica, cobraron impulso iniciativas dirigidas a la creación de un espacio educativo superior de carácter regional. Constituido en 1949, el Consejo Superior Universitario Centroamericano (CSUCA) fue la base sobre la que tales proyectos pivotaron. En ese contexto surgió el Instituto de Estudios Centroamericanos (IECA) (1972-1975), que adscrito a la Universidad de Costa Rica e impulsado por el filósofo de origen español Constantino Láscaris Comneno, desarrolló un ambicioso programa multidisciplinar entre cuyos objetivos se hallaba la confección de repertorios de fuentes históricas centroamericanas. El escenario de crisis abierto a partir del año 1974 incidió en tales iniciativas, lo que determinó la desaparición del IECA y de muchos de los proyectos por él alentados.Abstract: As a consequence of the trend of political and economic integration in Central America during the 1950’s, some initiatives concerning the creation of a space for regional higher education were launched.

Di Provinsi Sumatera Selatan berkembang beberapa pola kemitraan antara petani dengan pabrik pengolahan kayu karet. Penelitian bertujuan melihat pola kelembagaan pemasaran kayu karet di Provinsi Sumatera Selatan, kendala dan upaya untuk mengoptimalkan pemanfaatan kayu karet. Hasil penelitian diperoleh bahwa sumber kayu karet untuk industri saat ini sebagian besar (74%) berasal dari perkebunan rakyat dan 26% dari perkebunan besar. Sebanyak 68% petani yang meremajakan kebun karetnya sudah menjual kayu karet ke industri pengolahan kayu baik melalui supplier (73%) maupun menjual langsung ke pabrik (27%). Pola kemitraan yang sudah dilaksanakan oleh pabrik di antaranya memberikan bantuan modal kepada penangkar untuk diberikan kepada petani yang membutuhkan bibit karet, dan membantu petani yang membutuhkan bibit karet dengan memperhitungkan harga kayu. Akses jalan kebun serta sistem kelengkapan administrasi bagi penjualan kayu karet masih menjadi kendala dalam pemasaran kayu karet. Perlu penyederhanaan perizinan untuk pemasaran kayu yang berasal dari tanaman budidaya seperti karet serta perbaikan sarana jalan menuju kebun untuk menjaga keberlangsungan industri kayu karet. Diterima : 6 Desember 2012; Disetujui : 8 Maret 2013 How to Cite : Agustina, D.

KARAKTERISASI KONDISI PENGGUMPALAN DAN MUTU KARET YANG DIGUMPALKAN DENGAN KOAGULAN DEORUB FORMULA BARU
Authors: Vachlepi Afrizal , Suwardin Didin , Purbaya Mili
Published: December 2020

Penggunaan koagulan menentukan kondisi penggumpalan dan mutu karet yang akan dihasilkan. Koagulan anjuran, asam format dan asap cair murni, masih belum digunakan secara luas oleh petani karet. Asam format menghasilkan bokar berbau busuk, berbahaya bagi manusia dan lingkungan serta harganya mahal. Sedangkan asap cair murni memerlukan konsentrasi dan dosis yang lebih banyak sehingga kurang ekonomis. Sekarang ini sudah dikembangkan koagulan Deorub formula baru yang memiliki kelebihan dibandingkan kedua koagulan anjuran tersebut. Tujuan penelitian ini adalah untuk mengetahui dan mempelajari karakteristik kondisi penggumpalan dan mutu karet yang digumpalkan dengan koagulan Deorub formula baru. Parameter yang diamati terdiri atas kondisi penggumpalan, kadar karet kering koagulum, karakteristik karet mentah, mutu teknis, karateristik vulkanisasi, dan sifat fisik vulkanisat karet yang dihasilkan. Hasil penelitian menunjukkan bahwa waktu, pH penggumpalan, mutu teknis, modulus torsi, dan sifat fisik vulkanisat karet yang digumpalkan dengan koagulan Deorub formula baru tidak berbeda dibandingkan asam format dan lebih baik dari Deorub K. Koagulum yang digumpalkan dengan Deorub formula baru ini mempunyai warna coklat muda dan bau asap ringan dengan kadar karet kering lebih tinggi. Mutu teknis karet dari kedua koagulan juga tidak berbeda nyata. Diterima : 15 April 2015; Direvisi : 30 Juni 2015; Disetujui : 3 Agustus 2015  How to Cite : Vachlepi, A., Suwardin, D., & Purbaya, M.

Published: December 2020

Ekspor karet alam Indonesia masih didominasi SIR 20 yang digunakan sebagai bahan baku produksi ban. Untuk mengurangi konsumsi energi, sebagian pabrik ban sudah mulai mensubstitusi karet SIR 20 dengan jenis mutu yang lebih sesuai berupa karet viskositas mantap dan viskositas rendah. Kedua jenis karet alam ini mampu mengurangi konsumsi energi. Penambahan aditif diperlukan untuk memproduksi karet viskositas rendah. Penelitian ini bertujuan untuk mengetahui dan mencari aditif terbaik dari kelompok senyawa garam ammonium yang dapat digunakan dalam pembuatan karet alam viskositas rendah sesuai dengan persyaratan mutu ekspor. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan satu faktor perlakuan, yaitu jenis bahan aditif terdiri dari ammonium sulfat, ammonium klorida, ammonium dihidrogen fosfat dan ammonium nitrat  serta HNS sebagai kontrol dengan dosis 0,15% berat per berat (b/b) karet kering dan tanpa aditif (blanko). Parameter yang diamati terdiri atas kondisi penggumpalan (pH dan waktu penggumpalan), Po, PRI, ASHT, viskositas Mooney, SVI, kadar abu dan kadar gel. Hasil penelitian menunjukkan bahwa hanya dua jenis senyawa garam ammonium yang dapat digunakan sebagai aditif untuk menghasilkan karet viskositas rendah yaitu ammonium sulfat dan ammonium dihidrogen fosfat.

EKSPLORASI BAKTERI ENDOFITIK DAN POTENSINYA DALAM PENGHAMBATAN JAMUR AKAR PUTIH (RIGIDOPORUS MICROPORUS)
Authors: Setyawan Budi , Berlian Intan , Prasetyo Nur Eko
Published: December 2020

Salah satu cara pengendalian jamur akar putih (JAP) yang memiliki potensi besar untuk dikembangkan dimasa mendatang adalah secara biologi dengan memanfaatkan mikroba antagonis. Pada berbagai komoditas termasuk tanaman karet, bakteri endofitik antagonis telah dimanfaatkan untuk menghambat pertumbuhan patogen. Penelitian ini dilakukan untuk mengeksplorasi, mengidentifikasi bakteri endofitik dari tanaman karet serta menguji potensinya sebagai antagonis terhadap Rigidoporus microporus. Lima isolat berhasil diisolasi dari tanaman sehat di areal endemik JAP (isolat A10, A14, A16) dan areal non endemik JAP (isolat GN1, GN2). Uji oposisi langsung menunjukkan isolat A10 memiliki zona penghambatan terbesar (0,3 cm) pada 4 hari setelah inokulasi dibandingkan isolat lainnya. Identifikasi secara molekuler berdasarkan sekuens gen parsial 16S rRNA dan gen gyrase subunit B terhadap isolat A10 adalah Bacillus cereus. Aktivitas enzim protease ditunjukkan oleh isolat A10 pada medium skim milk dan kemampuannya mencairkan gelatin pada hari keenam setelah inokulasi. Kemampuan menghambat filtrat ekstraseluler yang diuji dengan metode paper disk belum menunjukkan zona penghambatan yang konsisten pada tiap konsentrasi filtrat ekstraseluler yang diberikan. Pada hari ketiga setelah inokulasi (HSI) tidak terdapat perbedaan nyata antar perlakuan. Pengujian lebih lanjut terhadap B. cereus isolat A10 perlu dipertimbangkan kembali karena potensi antagonismenya yang masih lemah terhadap R. microporus dan adanya potensi lain sebagai penyebab penyakit bagi manusia.
Nation and Religion: towards Definition of Religious Nationalism
Authors: Sitnikov Alexey V.
Published: December 2020

The aim of the article is to study the phenomenon of religious nationalism, i.e. cases when religion and nationalism are closely related and reinforce each other, and religious identity becomes an important and integral part of national identity. The author aims to analyze the political context of cases of religious nationalism in European countries, to describe their essential features and conditions of occurrence, and also to answer the question: are there any political reasons for religious nationalism? Considering the phenomenon of nationalism in the framework of the constructivist approach, the author also employs the methods of comparative analysis, using material from such countries as Ireland, Poland, Greece, the countries of the former Yugoslavia, as well as the Russian case taking place in the Chechen Republic. Summarizing these cases, the author describes the conditions for the emergence of an alliance of religion and nationalism. Firstly, it is a religious difference between neighboring communities. Secondly, it is a conflict between them, which contains a threat to identity. In these cases, religion becomes an important marker that distinguishes communities from each other, and begins to perform non-religious functions: the affirmation of national identity, ethnic pride, national honor, protection of sovereignty, and culture. Religious nationalism always stimulates growth of religious commitment of a nation, in which the number of believers may reach 90 percent. But this commitment is not individual, it is not based on a personal choice of faith, but collective and obligatory. Religious affiliation is dictated by loyalty to the nation.

This study is aimed to use fly ash and limestone as raw materials for preparing alkali methoxide heterogeneous catalysts for transesterification of palm oil into biodiesel. The heterogeneous catalyst was synthesized from fly ash and limestone through wet and dry methods and calcined within 1073–1273 K. X-ray diffraction and scanning electron microscopy analyses indicated the well-dispersed presence of the Ca(OCH3)2 crystal over the fly ash and limestone framework, which was mixed using wet method and calcined at 1073 K (W-800). Results showed that W-800 exhibited larger surface area and more uniform active sites than the other catalysts. About 88.6 % of biodiesel was produced from commercial palm oil with W-800 as the catalyst. The product possesses physicochemical characteristics, such as density, kinematic viscosity and free fatty acid content, which satisfy the international biodiesel standard. The catalyst was used for biodiesel production for four cycles, and the biodiesel yield was maintained up to 91.87 % from the initial value.

This study aimed to assess and demonstrate patient awareness regarding their oral cytotoxic drugs regimen in Radiation and Isotopes Center at Khartoum (RICK), as it considered one of the essential hospital cancer treatments in Sudan. Method: Across-sectional study was carried out at (RICK) hospital outpatient pharmacies. Data were collected by interviewing 100 patients and answering question about their drug regimen, side effects & management, handling & storage and drug/food/herb interactions. Result: The study showed that 46% of participants have missing knowledge about their drug using and taking. Complaints reported by patients, when using their drugs, vary. Myelosuppression is the most common (40.2%). In side effect management, the study showed that 26% of the patients are referred to the community pharmacy and 67% are using medication without a prescription. Regarding the awareness of using herbal treatments, 42% of patients are using or have used herbs with their drugs. 69% of patients using herbs said that they do not inform the caregiver. For the proper drug handling and storage in the home setting, 59.6% of patients said they did not receive instructions about handling and storage. The degree of patient knowledge about the proper handling and storage are variable. Finally, patient's knowledge about their drug regimen was significantly associated with drug education, an age of 13-45 years and regularity of clinic visits (p =0.018). Conclusion: The study concluded that awareness of patients is very low regarding the toxicity of these drugs and education of patients for oral cytotoxic chemotherapy vary substantially. The development of therapeutic educational programs is essential to ensure safe practice when using oral cytotoxic drugs.

The authors give specific examples of contemporary Russian and international practice to illustrate this thesis. The authors also examine new formats of inter-Parliamentary cooperation that are necessary to meet the challenges of the multi-polar world and assess their potential and perspectives.
A.I. Solzhenitsyn Apropos of Russia’s Future: Specific Outlook Features Depending on Different Historical Context
Authors: Zheltikova Inga V. , Khokhlova Elena I.
Published: December 2020

The article considers the dependence of the images of future on the socio-cultural context of their formation. Comparison of the images of the future found in A.I. Solzhenitsyn’s works of various years reveals his generally pessimistic attitude to the future in the situation of social stability and moderate optimism in times of society destabilization. At the same time, the author's images of the future both in the seventies and the nineties of the last century demonstrate the mismatch of social expectations and reality that was generally typical for the images of the future. According to the authors of the present article, Solzhenitsyn’s ideas that the revival of spirituality could serve as the basis for the development of economy, that the influence of the Church on the process of socio-economic development would grow, and that the political situation strongly depends on the personal qualities of the leader, are unjustified. Nevertheless, such ideas are still present in many images of the future of Russia, including contemporary ones.
Liberal Totalitarism: The Foundation of the Conceptual Synthesis
Authors: Tyapin Igor N.
Published: December 2020

The article is devoted to the problem of transformation of the ideology and practices of the globalist ultra-liberalism in the socio-political model of liberal totalitarianism. The first signs of the Western system evolution in that direction were noted and described by A.I. Solzhenitsyn when delivering the commencement address at Harvard University. The author of the article offers a review of the bibliography on the problem that highlights the key approaches of a number of authors, representing different niches of the political spectrum. As part of the review the author determines the connection of liberal totalitarianism with the phenomenon of pseudo-science, institutions of global superpower, the ideology of anti-morality, sophistical discourse of postmodernism, as well as the implementation of the new totalitarian model, consisting in the transition from the constant and sophisticated consciousness manipulation technology to the spiritual and physical dehumanization. On the basis of the synthesis of the foreign and domestic philosophy achievements and original practices, the author distinguishes a wide range of the specific characters of the liberal totalitarianism model that can serve as conceptual and methodological basis for the modern political regimes classification.
Yu. F. Samarin’s Views on Popular Representation in the Context of Slavophil and Liberal Political Thought in Russia
Authors: Demin Vadim A.
Published: December 2020

In the article the author analyzes the views of Yu. F. Samarin, – one of the leaders of Slavophil trend, on the popular representation, comparing his views with those of other Slavophiles and moderate Westerners on this problem, thus making up for certain deficiency in Russian political science. The article shows the evolution of Slavophiles’ views on the issue of popular representation: from the appeal for organizing local self-administration without forming at that representative power at the national State level, and to the initiatives to organize the representative power that could serve as counterweight to the reforms of Alexander II, and to the subsequent idea of recreating the specific Russian historic institution – Zemsky Sobor. However, Yu. F. Samarin turned out to be the most conservative one among Slavophilism ideologists regarding the popular representation. He was almost the only one who considered Russian monarchy of the 19th century to be in full compliance with the principle of nationality while retaining solid unity with the people. Accordingly Samarin was a consistent defender of absolute autocracy and did not consider it necessary to supplement it with representative institutions.

The author of the article is mostly interested in the contribution of Slavophils to the formation of Russian nationalism, and in particular, the contribution of the prominent theorist and practitioner of Slavophilism Yuri Fedorovich Samarin (1819–1876). How potent were the nationalistic or imperial components in conservative ideology? How complex were their contradictions, or on the contrary, their symbiosis? What was the contribution of the Slavophils and personally Samarin in the formation of Russian nationalism in its soilborne (“pochvenny”), conservative version?

Published: December 2020

Kitlesel Açık Çevrimiçi Dersler (KAÇD) eğitim alanındaki son yıllardaki gelişmelerde geniş ölçekli bir etkiye sahiptir. Bu derslerin tasarımı, özellikle çevrimiçi ve açık öğrenme kavramlarına yeni boyutlar kazandırmış ve öğretim tasarımı sürecine yönelik yeni bakış açılarının gelişmesine katkı sağlamıştır. Bilgi ve iletişim çağında değişen öğrenen ihtiyaçları, beklentileri ve profilleri de bu süreçte yeni tanımlamalar kazanmıştır. Öğrenen deneyimlerine yönelik çalışmalar mevcutken, geniş ölçekli olan bu derslerin tasarlanması ve bu sürecin öğreticiler açısından incelenmesine yönelik ise daha fazla çalışma yapılması gerektiği belirlenmiştir. Bu çerçevede, bu çalışmanın asıl amacı hem öğrenen hem de öğretici bakış açısına sahip olan kişilerin KAÇD ile ilgili yaşadıkları deneyimler dahilinde düşüncelerini, yaşadıkları zorlukları ve muhtemel çözüm önerilerini ortaya koymaktır. Çalışmanın ikincil amacı ise bir KAÇD ortamının tasarım ve uygulanma sürecini detaylı incelemektir. Bu amaçlar çerçevesinde, bu çalışma tekli durum çalışması olarak tasarlanmış olup, durum hayata geçirilen bir KAÇD ortamı olarak belirlenmiştir. Çalışma verileri bu dersin tasarım ve uygulama sürecinde yer alan 10 kişiden oluşmakta olup, veriler nitel veri analiz yöntemiyle yorumlanmıştır. Çalışmanın sonuçlarına göre hem öğrenen hem de eğitmen deneyimlerine yönelik görüşler genelde olumlu olup özellikle bu süreçlerin profesyonel, mesleki ve bireysel gelişime katkı sağladığı fikrinde uzlaşılmıştır. Öğrenen deneyimlerinde ortaya çıkan zorluklar iletişim, motivasyon başlıklarında toplanırken, eğitmenlerin yaşadıkları zorluklar ise tasarım, uygulama ve değerlendirme başlıkları altında incelenmiştir. Bu çalışmada ortaya çıkan sonuçlara göre, öncesinde çevrimiçi öğrenme deneyimi olan eğitmenlerin KAÇD ortamını tasarlama sürecinde karşılaştıkları zorluklar, bu tarz öğrenme ortamların nasıl tasarlanacağından ziyade yüksek katılımcı sayısının beraberinde getirdiği yeni durumlarla nasıl baş edeceklerine yönelik durumlar ve stratejileri içermektedir.
