Authors: Jeffison Nyambishi Tatenda , Mwale Eng. Dr. Kasongo Richard
Published: March 2021

Purpose: The aim of the study was to establish strategies that can counter smuggling of beverages and improve business performance for The Cold Chain Zambia ltd. Smuggling poses a threat to the business as it destabilizes the legal industry of supply chain, restrains innovation and investments as well as posing a threat of company closures. Smuggling has caused loss of consumer confidence in buying beverages from Cold Chain Zambia ltd as the products are perceived to be expensive as compared to similar smuggled beverages in the market. The objectives of the study were to determine the extent of the effects of beverage smuggling on the Cold Chain Zambia business performance, to identify strategies which will counter beverage smuggling and to establish strategies that can be used to counter beverage smuggling and improve Cold Chain Zambia business performance.Methodology: The research design that was used was mixed methods which took the form of exploratory sequential mixed method design. The target population was 80 employees from Cold Chain Zambia ltd which included both general staff and management staff.Findings: There seems to be no correlation between business performance and strategies to counter beverage smuggling. In this case, H3: There is a significant correlation between the business performance and the perception of strategies to counter beverage smuggling in cold chain supply and was rejected. It was found that there is a negative and significant correlation between beverage smuggling and strategies to counter beverage smuggling on business turnover (F = 14.339; p<0.001).Unique contribution to theory, policy and practice: The researcher recommended that smuggling can be reduced by ensuring the goods are sold at competitive prices to reduce benefit of smuggling, continue with quality control, educate the public on smuggling and how to report and identify smuggling, stiffen law on smuggling in Zambia and review the clearing procedure at all points of entry to fasten the process.
CAUSES OF DELAY IN CLEARANCE OF GOODS AT THE PORT OF MOMBASA
Authors: Wanyama Tabitha
Published: March 2021

Purpose: The study was an investigation into the challenges facing clearing and forwarding activities at the port of Mombasa.Methodology: The study adopted an exploratory study design which was descriptive in nature. A population of 265 was used out of which a sample of 100 respondents was chosen. To select the 100 sampling units/respondents, the researcher used purposive sampling method.  The data was collected using questionnaires which had both open and closed ended questions.  The methods used in the analysis of the data were descriptive statistics such as percentages, frequencies, pie charts and cross-tabulation.Results: Findings in the study indicated that some of the challenges facing clearing and forwarding processes at the port of Mombasa included poor education and training of clearing agents, abandonment of goods by agents due to poor pricing, lack of automation, low level mechanization, bureaucratic processes from governmental agencies and poor road network which causes congestion. In conclusion, the research identified that the challenges were both human resource oriented (inadequately skilled workforce) as well as systemic (resulting from a failure in the coordination between the various players in the clearing system).Unique contribution to theory, practice and policy: It was recommended in this study that the various players such as KRA, KPA, governmental agencies, importer/exporters, clearing agents among others should improve their individual processes and efficiency to enhance coordination and faster clearing. It was recommended that a further study should be carried out by both the KPA and the KRA management involving a larger population and sample to reflect the strategies that other major ports in the world have undertaken to enable them ease the congestion at their ports so that they find out what factors need to be implemented to fasten the clearance. Further study should also include stakeholders outside the clearing and importers fraternity such as the government, and the community as a whole.
AN ANALYSIS OF LOGICAL CONSISTENCY IN THE APPLICATION OF LEAN TECHNIQUES TO IMPROVE BUSINESS PROCESSES AND SERVICE DELIVERY: A CASE OF DEPARTMENT OF FIELD SUPPORT (DFS), UNITED NATIONS
Authors: Kemokai Michael Boima
Published: March 2021

Purpose: The purpose of this study was to establish the logical consistency in the application of lean techniques to improve the DFS business processes and service delivery and to create logistical pinch-points that improved the logistics and physical distribution of goods from the GSC and RSC to Field Missions.Methodology: The study employed a qualitative research design. The study targeted all the senior managers at Director Levels at the GSC and the RSC and all the senior operational staff from supply chain and service delivery pillars in three (03) large Field Missions. These field missions are namely United Nations Stabilization Mission in Congo (MONUSCO); United Nations Mission in South Sudan (UNMISS); and the United Nations Support Office for AMISOM (UNSOA). This study used purposive sampling technique. The researcher purposively sampled fifteen (15) personnel; with three (03) participants each from the GSC, RSC, and three (03) participants each from the three (03) Field Mission. Primary data was obtained from the original sources using questionnaires and interview.Findings: The respondents indicated that the logical consistencies observed needed an understanding, through measurement, a reordering model that included lead time, reorder point, and safety stock.  The respondents also indicated that the consistencies observed mainly relates to the overall approach of being more customer oriented while trying to optimize business processes and workflows. However, the respondents indicated that there were limitations in how the various organizations diversely applied lean concepts. There was no clear guidance provided on areas requiring higher prioritization; consistency throughout the departments, divisions and, missions when changes are applied (i.e. in structures, and functional organizational units). Additionally, lean analyzes were conducted mainly by internal resources that may not have been completely objective on areas being investigated, therefore bringing bias and subjectivity. Internal resources using lean techniques may not have been complete. Finally, the respondents indicated that there is no clear guidance yet. Policies and training have to be provided to staff prior implementing lean techniques.Unique contribution to theory, practice and policy: The study recommends that there is need to establish formal strategic plans to direct and align the work of the organization and supported by objectives and data-driven performance monitoring, analysis, and reporting. The study also recommends that there is a need for more efficient monitoring and evaluation of all GA resolutions and audit recommendations. The organization needs to monitor the manner of compliance with the provisions of the memorandums of understanding.

Perangkat lunak yang digunakan untuk membuat EIGRP (Enhanced Interior Gateway Routing Protocol) dan DUAL (Algoritma Pembaruan Pembaruan) simulasi menggunakan Cisco Packet Tracer. Dari hasil pengujian simulasi membuktikan bahwa jalur terbaik untuk dilalui oleh setiap router, yaitu jalur / rute yang memiliki perhitungan metrik EIGRP terkecil di antara rute tetangga, perhitungan ini diperoleh dari parameter bandwidth dan delay pada setiap router yang terhubung.
One War, Multiple Memories
Authors: Beşikçi Mehmet
Published: March 2021

This article surveys Ottoman reserve officers’ autobiographical texts and emphasizes the potential these personal narratives present to revise both the existing historiog- raphy on the Ottoman First World War and the official memory of the war in Turkey. After briefly exploring the evolution of the Ottoman reserve officer system as an in- tegrated part of Ottoman conscription, the article shows how reserve officers’ war memories shed light on the neglected aspects of Ottoman soldiers’ experience of the front, particularly the daily life of trench warfare. Reserve officers’ personal narratives include critical observations and remarks about the Ottoman war experience, and the article discusses how these critical memories may be significant for the revision of the official narrative of the war in Turkey. Yet it also argues that as these personal nar- ratives are diverse, they do not present an all-embracing counter-narrative of disil- lusionment. The article also draws attention to the shaping effect of the context in which these autobiographies were written down and explores the organic ties between personal and collective memories of the Great War in Turkey.
Ha-Balkan Ha-Bo‘er (The Balkans in Flames)
Authors: Ginio Eyal
Published: March 2021

Ha-Balkan Ha-Bo‘er (The Balkans in Flames), the memoirs of Yitzhak Halperin, are at the center of this article. Born in Palestine in 1890, Halperin was part of the so-called “first generation” – meaning Jews, natives of the newly established colonies in Palestine, who conversed in the Hebrew language and whose life and social productivity embodied the Zionist vision of the nation. Halperin volunteered to serve in the Ottoman Army in November 1911. Later, during the first weeks of the First Balkan War (October 1912-May 1913), he served on the Macedonian front before fleeing to Salonica, where he deserted.  Published in Hebrew in 1932, Halperin’s memoirs can be read against both Zionist and Ottoman contexts. They shed light on various personal experiences and perceptions that can enrich our understanding of his particular ideological and ethnic group. In addition, his memoirs are unique as they describe the daily experiences of an Ottoman rank-and-file soldier who served in the Balkan Wars. As such, it offers different insights into the broader Ottoman context. Halperin’s memoirs expose two main topics: the related issues of identity, sociability, and friendship as they developed among the conscripts during his military service; and his clear disappointment with the poor performance and low morale of the Ottoman army before and during the Balkan Wars.
Living Through Wartime
Authors: Van Os Nicole A. N. M.
Published: March 2021

Archival sources, but also self-narratives, newspapers, and periodicals, have been im- portant sources for political and military historians of the last two decennia of the Ot- toman Empire in general and the First World War in particular. In recent years, an increasing number of historians have become interested in more than the political and military history of the period. The field has been broadened to include social history. Conventional sources have been reread to get a better understanding of the effects of the War on the social domains and everyday life. Self-narratives have proven to be in- valuable sources for social historians working on the period. These self-narratives were not only produced by the men in charge, but by people from all walks of life: soldiers and civilians, men and women noted down their wartime experiences in their diaries or letters home and in memoirs and autobiographies. In most cases, the self-narratives used by historians were, however, those written by men in which women were objecti- fied. In this paper, the self-narratives of women living in the Ottoman Empire during the First World War are preliminarily explored to give them a voice and turn them into subjects rather than objects.
Cpt. Robert Hofmann, Austrian Artillery Officer and Artist with the Ottomans in World War I
Authors: Schull Kent F.
Published: March 2021

This article investigates the life, artwork, and experiences of Cpt. Robert Hofmann, an Austrian artillery officer and artist who fought with the Ottomans in the Levant from 1917 to 1919 during World War I and its immediate aftermath.  His experiences and artwork provide powerful and vivid insight into the life, times, and situations of war in the Middle East.  Unlike those of most of his European compatriots fighting with the Ottomans, his work and perspectives were from a distinctly non-Orientalist perspective as he sketched the flora and fauna, cityscapes, landscapes, and people he encountered while in the Ottoman Empire, particularly in the Levant.  His attention to detail and captivation by the everyday and mundane without an imperialist or Orientalist gaze begs explanation, particularly since he was a classically trained artist from the Imperial Academy of Fine Arts in Vienna.  This article asserts that the combination of his own marginalized identity as an assimilated Jewish soldier, his gifted artistic talent, attention to detail, and his direct and sustained experience in the Middle East enabled him to develop a deep sense of empathy and appreciation for the peoples, places, and environments of the Middle East. This enabled him to transcend the bigotry and dehumanizing views of non-Western peoples so prevalent among his compatriots and European powers of the time.
The Great War of the Postcards
Authors: Strauss Johann
Published: March 2021

This article examines the functions and the significance of picture postcards during World War I, with particular reference to the war in the Ottoman Lands and the Balkans, or involving the Turkish Army in Galicia. After the principal types of Kriegspostkarten – sentimental, humorous, propaganda, and artistic postcards (Künstlerpostkarten) – have been presented, the different theatres of war (Balkans, Galicia, Middle East) and their characteristic features as they are reflected on postcards are dealt with. The piece also includes aspects such as the influence of Orientalism, the problem of fake views, and the significance and the impact of photographic postcards, portraits, and photo cards. The role of postcards in book illustrations is demonstrated using a typical example (F. C. Endres, Die Türkei (1916)). The specific features of a collection of postcards left by a German soldier who served in Turkey, Syria, and Iraq during World War I will be presented at the end of this article.
The Aesthetics of War
Authors: Eldem Edhem
Published: March 2021

War has always been a catalyst for innovation in the Ottoman Empire, even in the un- likely field of iconography. World War I was such an episode, further exacerbated by the alliance with Germany, a major producer of wartime propaganda. This contribution retraces the development of state symbolism in the Ottoman Empire throughout the nineteenth century, especially with respect to medals and decorations, before focusing on the production of images and symbols during World War I. Particular attention is given to one specific case – that of the Ottoman War Medal, dubbed the “Iron Crescent” by the Germans, the creative design of which still remains unexplained and undocu- mented despite its truly iconic nature.

Authors: DeLong Jessica , Virasoro Ramón
Published: March 2021

Objectives: To describe the development of a genitourinary reconstructive fellowship curriculum and the establishment of the first genitourinary reconstructive and pelvic floor postgraduate training program in the Caribbean.
Methods: In an effort to respond to the need for specialty-trained reconstructive urologists in the Dominican Republic, we developed an18-month fellowship program to train local surgeons. The process began with creation of a curriculum and partnership with in-country physicians, societies, hospitals, and government officials. We sought accreditation via a well-established local university, and fellowship candidates were selected. A database was maintained to track outcomes. Subjective and objective reviews were performed of the fellows.
Results: The first fellow graduated in 2018, the second in 2020, and the third is currently in training. The curriculum was created and implemented. The fellowship has been successfully integrated into the health system, and the fellows performed 199 and 235 cases, respectively, during the program, completing all rotations successfully. They have been appointed to the national health system. Both graduates are now docents in the program and in the public system. Additional staff including radiologists, radiology technicians, nurses, urology residents (both Dominican and American), urology attendings, operating room staff, and anesthesia residents were trained as a result of the program.
Conclusions: To our knowledge, this is the first fellowship of its kind in the Caribbean. A novel curriculum was created and implemented, and the first 2 fellows have successfully completed all rotations. This training model may be transferable to additional sites.
Estimation of CO2 Emission Savings from a Metro Rail System Using Different Methodologies: A Case Study of Mumbai, India
Authors: Pradeep Chaitanya Jasti
Published: March 2021

Estimating ‘CO2 emission savings’ of a mass rapid transit system (MRTS) project shall give an opportunity to earn carbon credits under clean development mechanism (CDM) of Kyoto protocol for ‘Non-Annex I’ countries like India. In this study, two methodologies for estimating ‘CO2 emission savings’ were demonstrated with a case study of Mumbai ‘metro line 1’. One considers actual reduction in vehicular traffic and the other considers the commuter shift to metro from other modes estimating the savings as 38.02 t/day and 27.63 t/day, respectively. Subsequently, sensitivity analysis was conducted to identify the optimal scenario for ‘CO2 emission savings’ supported by both the methods. Further, a breakeven scenario for ‘annual net CO2 emission savings’ after considering the indirect emissions due to electricity consumption by the metro system was also analysed as 1,008 t/year by the end 2019. These savings are analysed to further reach 32,537 t/year by 2025.

Background: Refractive surgery (RS) for myopia has made a very big progress regarding its safety and predictability of the outcome. Still, a small percentage of operations require retreatment. Therefore, both legally and ethically, patients should be informed that sometimes a corrective RS may be required. We addressed this issue using Neural Networks (NN) in RS for myopia. This was a recently developed validation study of a NN. 

Methods: We anonymously searched the Ophthalmica Institute of Ophthalmology and Microsurgery database for patients who underwent RS with PRK, LASEK, Epi-LASIK or LASIK between 2010 and 2018. We used a total of 13 factors related to RS. Data was divided into four sets of successful RS outcomes used for training the NN, successful RS outcomes used for testing the NN performance, RS outcomes that required retreatment used for training the NN and RS outcomes that required retreatment used for testing the NN performance. We created eight independent Learning Vector Quantization (LVQ) networks, each one responding to a specific query with 0 (for the retreat class) or 1 (for the correct class). The results of the 8 LVQs were then averaged so we could obtain a best estimate of the NN performance. Finally, a voting procedure was used to reach to a conclusion.

Results: There was a statistically significant agreement (Cohen’s Kappa = 0.7658) between the predicted and the actual results regarding the need for retreatment. Our predictions had good sensitivity (0.8836) and specificity (0.9186).

Conclusion: We validated our previously published results and confirmed our expectations for the NN we developed. Our results allow us to be optimistic about the future of NNs in predicting the outcome and, eventually, in planning RS.
How to Face COVID-19 in Ophthalmology Practice
Authors: Pei Xiaoting , Jiao Xinwei , Lu Dingli , Qi Di , Huang Shenzhen , Li Zhijie
Published: March 2021

Background: The novel coronavirus pneumonia has attracted considerable attention from the international community. With the spread of outbreaks around the world, the WHO characterized COVID-19 as a pandemic.

Methods: Relevant studies in PubMed were searched from January 1, 2020 to April 12, 2020, using the following search strategy: (“novel coronavirus pneumonia” OR “severe acute respiratory syndrome coronavirus 2” OR “coronavirus disease 2019” OR “COVID-19” OR “novel coronavirus pneumonia”) AND (“ophthalmology” OR “ophthalmologist” OR “eye” OR “conjunctiva” OR “conjunctivitis” OR “corneal” OR “keratitis”).

Results: SARS-CoV-2 can spread through aerosol and is detected in tears of patients with COVID-19 infection. Notably, some infected patients had conjunctivitis, and conjunctivitis was the first symptom in some patients later diagnosed to have COVID-19 infection. This would increase the risk for ophthalmologists through inpatient consultations or regular clinical practice. When dealing with seemingly regular ophthalmic patients, the vigilance of ophthalmologists and associated staff tends to be reduced.

Conclusion: Ophthalmologists must continuously update their knowledge regarding COVID-19 and take effective measures to prevent COVID-19 transmission.
Exergy analysis of petroleum refinery hydrogen network integration based on reaction system
Authors: KUTLU Özben , ÖZÇELİK F. Zehra
Published: March 2021

High-purity hydrogen is a crucial input in a crude oil refinery to upgrade several products. For this reason, the effective hydrogen management is necessary to satisfy hydrogen requirements. On the other hand, adding exergy analysis to the hydrogen pinch analysis especially for refinery plants, where hydrogen reacts under high temperature and pressure, helps improve the efficiency of unit by overcoming the lack of pinch analysis. The aim of this study is the simulation and exergy analysis of reactors within hydrogen network integration of a petroleum refinery retrofitted by pinch analysis before. Two hydrogen production and four consumption units were considered and simulated by Aspen Plus, and then the exergy efficiencies were calculated. Low exergy efficiencies were determined in the hydrogen production and hydrodesulfurization units, whereas the separation of excess hydrogen from the desired product considerably effected on the efficiency. The results also show that not only the hydrogen demand of reactors has to be reduced, but also the hydrogen recovery and purification is very important for the increase in efficiency. Although the processes are carried out at the high operating conditions, the reactions significantly affect the total exergy flow rate.

Molecularly-imprinted silica nanoparticles for rapid and selective detection of atenolol in artificial urine samples
Authors: ZENGİN Adem
Published: March 2021

Herein, a novel molecularly imprinted polymer was synthesized on silica nanoparticles via surface imprinting approach for rapid, sensitive and selective detection of atenolol in artificial urine samples. For this purpose, silica nanoparticles were firstly modified with methacryloxy group for surface initiated polymerization and then, polymerization was carried out in the presence of 2-hydroxyethyl methacrylate (functional monomer), ethylene glycol dimethacrylate (cross-linker), azobisisobutyronitrile (initiator), atenolol (template) and acetonitrile (porogen). The surface characterization of imprinted nanoparticles indicated that a thin polymer layer was grafted on the silica nanoparticles. The rebinding properties of the imprinted nanoparticles were investigated in detail and the results revealed that the imprinted nanoparticles had high adsorption capacity (32.06 mg/g), fast adsorption kinetics (15 min for equilibration), high imprinting factor (4.14) towards atenolol and good regeneration ability. The imprinted nanoparticles were also used as selective sorbent for selective extraction and determination of atenolol in artificial urine samples. The results showed that the proposed method good recovery percentages (98.6 %-100.1%) with low standard deviations (less than 4.4%). It is believed that the atenolol-imprinted silica nanoparticles can be used as an alternative sorbent for selective quantification of atenolol in artificial urine samples.
Political laws of pedagogy as a distortion of the historical mission of education (P. Blonsky)
Authors: Смирнов И.П.
Published: March 2021

Автор подвергает критике выведенные Павлом Блонским законы педагогики марксизма: «О классовой сущности педагогики», «Соответствие школы определенному общественному строю», «Цель школы – производственное образование». Заложенные в них, а также в выдвинутой Крупской и поддержанной Блонским концепции «трудовой школы» принципы образования рассматриваются как сознательное отступление от научных основ педагогики и пример выполнения ученым политического заказа.
В статье доказывается, что педагогика, как и любая наука, должна быть свободна от политики, подчиняться исключительно законам объективного познания. Для утверждения педагогики в статусе науки, она обязана выдавить из себя «политического раба», а ученый – перейти от педагогики страха к педагогике чести и достоинства.
Блонский Павел Петрович (1884–1941 г.г.) – русский и советский философ, психолог, педагог, один из основоположников советской педологии. Окончил историко-филологический факультет Московского университета, оставлен на кафедре философии для подготовки к профессорской деятельности, работал приват-доцентом. По рекомендации Н.К. Крупской становится членом научно-педагогической секции Государственного ученого совета, участвует в разработке учебных программ и в школьной реформе. Пользовался поддержкой А.В. Луначарского. В конце жизни работал в Институте психологии в Москве.

The author criticizes the laws of pedagogy of Marxism derived by Pavel Blonsky: "On the class essence of pedagogy", "Correspondence of the school to a certain social order", "The goal of the school is industrial education". The principles of education embedded in them, as well as in the concept of “labor school” set forward by Krupskaya and supported by Blonsky, are considered as a deliberate departure from the scientific foundations of pedagogy and an example of the fulfillment of a political order by scientists.
The article proves that pedagogy, like any science, should be free from politics, subject exclusively to the laws of objective knowledge. To establish pedagogy in the status of science, it must squeeze out of itself a "political slave", and a scientist must move from the “pedagogy of fear” to the “pedagogy of honor and dignity”.
Blonsky Pavel Petrovich (1884–1941) is a Russian and Soviet philosopher, a psychologist,a teacher, one of the founders of the Soviet pedology. He graduated from the Faculty of History and Philology of Moscow University, remained at the Department of Philosophy to prepare for professorship, worked as a privat-docent. According to the recommendation of N.K. Krupskaya, he becomes a member of the scientific and pedagogical section of the State Academic Council, participates in the development of curricula and in school reform. Enjoyed the support of A.V. Lunacharsky. At the end of his life he worked at the Institute of Psychology in Moscow.

Published: March 2021

В статье представлены теоретико-методологические основы построения онтологической модели идентичности системы профессионального образования, которая может быть использована для разработки качественных методик педагогической компаративистики. Основой для онтологической модели послужили принцип трансдисциплинарности, контекстный и коммуникативный подходы с соответствующими им методами «веерной матрицы» и «сети», в рамках которых разработаны структура, основные элементы и алгоритм пошагового построения онтологической модели. Основными элементами онтологической модели являются контексты, подконтексты и их производные, которые раскрываются при воссоздании онтологической модели идентичности конкретной национальной системы профессионального образования. Описана инструментальная функция онтологической модели, реализуемая в процессе образовательного трансфера и прогнозирования трансформации идентичности системы профессионального образования. Эмпирическая часть исследования была проведена в ФРГ, Турецкой Республике и Российской Федерации.

The article presents theory and methodology bases of ontological model design. The ontological model of vocational education system identity is supposed to be used as a comparative education study tool. The ontological model is based on the trans-disciplinary principle, context approach and communicative approach, fractal matrix tables method and the "network" method. The structure of ontological model, the “step by step” algorithm are developed according to the fractal matrix tables and "network" methods terms. The ontological model consists of contexts and sub-contexts, which are supposed to be revealed in derivatives in the process of recreating the ontological model. The article describes the instrumental function of the ontological model in relation to comparative analysis, the process of educational transfer and identity transformation forecast. The empirical part of the study was carried out in the Federal Republic of Germany, the Turkish Republic and the Russian Federation

Показано, что существующие механизмы применения указанных компонент не в полной мере отвечают целям и задачам внедрения геймификации как средства повышения мотивации в учебной деятельности. В связи с этим целью работы является разработка системных подходов и механик для повышения практической значимости и переосмысления элементов триады PBLв образовательном процессе вуза. Предложена модификация компонент PBL, позволяющая увеличить вовлеченность студентов в процесс обучения. Полученные результаты могут быть интересны преподавателям вузов, использующим в своей профессиональной деятельности игровые технологии.

The article is devoted to the issues of enhancing game techniques in the educational process of the university. The relevance of the study is due to the need to modernize the learning process in accordance with the tasks of digitalization of education. The problem and possibilities of using PBL components (Points, Badges, Leaderboards) in the educational process are analyzed. It is shown that the existing mechanisms for using these components do not fully meet the goals and objectives of introducing gamification as a means of increasing motivation in educational activities. In this connection, the aim of the work is to develop systemic approaches and mechanics to increase the practical significance and rethink the elements of the PBL triad in the educational process of the university. A modification of the PBL components is proposed to increase student involvement in the learning process. The results obtained may be of interest to university teachers who use gaming technologies in their professional activities.

Published: March 2021

В статье рассматриваются актуальные проблемы оптимальности применения современных информационно-компьютерных технологий и технических средств обучения на уроках математики в средней школе с целью развития интеллектуальных способностей школьников. Методы исследования – анализ профильной литературы и обобщение прогрессивного педагогического опыта. В результате проведенного исследования определяются часто встречающиеся проблемы применения информационно-компьютерных технологий, заключающиеся в дистанцировании школьников от непосредственной познавательной активности, снижения способностей к адаптивной интеллектуальной деятельности, развития механичности действий. Авторами доказывается значимость выверенного баланса применяемых традиционных педагогических методов и современных решений; приводятся конкретизированные методические рекомендации, способствующие стимулированию интереса и интеллектуальной активности школьников на уроках математики. Предлагается широко вводить в практику обучения математике такие педагогические средства стимулирования интеллектуальной активности школьников, как разбор неправильных процедурных действий, применение заданий на индуктивную логику, проблематизация заданий, привязка заданий к практике.

The article deals with the current problems of optimal application of modern information and computer technologies and technical means of teaching mathematics in high school in order to develop the intellectual abilities of students. The methods of research are analysis of specialized literature and generalization of progressive pedagogical experience. As a result of the conducted research, the frequently encountered problems of using information and computer technologies are identified, which consist in distancing students from direct cognitive activity, reducing the ability to adaptive intellectual activity, and developing mechanical actions. The authors prove the importance of a substantiated balance of traditional pedagogical methods and modern solutions, and provide specific methodological recommendations that help stimulate the interest and intellectual activity of students in mathematics lessons. It is proposed to widely introduce into the practice of teaching mathematics such pedagogical means of stimulating the intellectual activity of school-children as the analysis of incorrect procedural actions, the implementation of tasks for inductive logic, problematization of tasks, linking tasks to practice.

Authors: Кузнецова А.А.
Published: March 2021

Данная статья является продолжением описания исследования, которое проводилось нами в 2018 году и было опубликовано в № 2 (133) Казанского педагогического журнала в 2019 году. В прошлой статье мы рассматривали взаимосвязь отношений привязанности с уровнем развития креативности в дошкольном возрасте. А в данной статье рассматривается продолжение исследования, где изучается проблема соотношения наличия элементов компьютерной зависимости и отношений привязанности в дошкольном возрасте. Целью статьи является представление и описание проведённого продолжения исследования, рассмотрение этапов исследования и его результатов. Данная работа проводилась на группе дошкольников, возраст которых составил от четырёх с половиной до пяти с половиной лет. Нами была сформулирована гипотеза о наличии связи между элементами компьютерной зависимости и отношениями привязанности в дошкольном возрасте. Исследование проходило на базе частного детского образовательного учреждения «Академика» в городе Реутов с использованием методик диагностики наличия элементов компьютерной зависимости и отношений привязанности на выборке более шестидесяти человек. Результаты исследования продемонстрировали подтверждение выдвинутой гипотезы о существовании взаимосвязи между наличием элементов компьютерной зависимости и отношениями привязанности в дошкольном возрасте. В данной статье приведены результаты исследования, а также описаны перспективы его использования в психологии и педагогике.

This article is a continuation of the description of the study which we conducted in 2018 and was published in № 2 (133) of the Kazan Pedagogical Journal in 2019. In the latest article, we examined the relationship between attachment relationships and the level of creativity development in pre-school age. This article discusses the continuation of the study, which studies the problem of the correlation between the presence of elements of computer addiction and attachment relationships in preschool age. The purpose of the article is to present and describe the continuation of the study, review the stages of the study and its results. This work was carried out on a group of pre-schoolers whose age ranged from four and a half to five and a half years. We have formulated a hypothesis about the existence of a connection between the elements of computer addiction and attachment relationships in preschool age. The study was carried out on the basis of a private children's educational institution "Akademika" in the city of Reutov using methods for diagnosing the presence of elements of computer addiction and attachment relationships in a sample of more than sixty people. The results of the study have demonstrated confirmation of the hypothesis put forward about the existence of a relationship between the presence of elements of computer addiction and attachment relationships in pre-school age. This article presents the results of the study, as well as describes the prospects for its use in psychology and pedagogy.
Basic beliefs and network activity strategies of students
Authors: Сунгурова Н.Л. , Цвекс М.В.
Published: March 2021

В статье представлены результаты теоретико-эмпирического исследования особенностей базисных убеждений студентов с разными стратегиями сетевой коммуникации. Базисные убеждения выделены как личностные компоненты, детерминирующие выбор поведения в сетевой коммуникации. Авторами использовались методика «Шкала базисных убеждений» (World assumptions scale – WAS) Р. Янов-Бульман (О. Кравцова), «Опросник установок по отношению к Интернету» (Э. Губенко), «Опросник поведения в Интернете» (А. Жичкина). В статье описаны взаимосвязи и результаты сравнительного анализа по направлениям профессиональной подготовки базисных убеждений, стратегий сетевой активности и установок по отношению к Интернету. Показано, что студентам с выраженными «ресурсными» базисными убеждениями характерно конструктивное пользование Интернетом. Превалирование «нересурсных» базисных убеждений студенческой молодежи может способствовать их ориентированности на проблемное пользование Интернетом. Статья предназначена для психологов, преподавателей вузов и исследователей в области психологии личности в контексте информационно-коммуникационных технологий.

The article presents the results of a theoretical and empirical study of the features of the basic beliefs of students with different strategies of network communication. Basic beliefs are highlighted as personal components that determine the choice of behavior in network communication. The authors used the methodic «World assumptions scale – WAS» by Ronnie Yanov Bulman (O. Kravtsova), "Questionnaire of attitudes towards the Internet" (E. Gubenko), Internet Behavior Questionnaire (A. Zhichkina). The article describes the relationship and the results of a comparative analysis in the areas of professional training of basic beliefs, strategies of network activity and attitudes towards the Internet. It is shown that the students with pronounced “resource” basic beliefs are characterized by constructive use of the Internet. The prevalence of “non-resource” basic beliefs among student youth can contribute to their focus on problematic Internet use. The article is intended for psychologists, University-teachers and researchers in the field of personality psychology in the context of information and communication technologies.
