Распределение Дикмана-Гончарова
Authors: Molchanov Stanislav Alekseevich , Panov Vladimir Alexandrovich
Published: November 2020

В 30-е и 40-е годы двадцатого века в работах двух математиков - Карла Дикмана и Василия Леонидовича Гончарова, - занимавшихся совершенно разными задачами, возникло одно и то же уравнение с запаздыванием. В то время как в оригинальной статье Дикмана исследовалось предельное значение количества натуральных чисел без больших делителей, работа Гончарова была посвящена анализу асимптотики длины максимального цикла в разложении случайной подстановки.
Полученное в этих работах уравнение при некотором начальном условии задаeт плотность вероятностного распределения, называемого теперь распределением Дикмана-Гончарова (ДГ; термин впервые предложен в 1986 г. А. М. Вершиком). В последнее время появился целый ряд совершенно новых приложений распределения ДГ как в математике (случайные блуждания на разрешимых группах, теория случайных графов и т. д.), так и в биологии (модели роста и эволюции одноклеточных популяций), финансах (теория экстремальных явлений в финансах и страховом деле), физике (модель случайных энергетических уровней) и других областях.
Несмотря на обширную область применения этого распределения и более общих, но родственных моделей, все математические аспекты данной тематики (например, свойства безграничной делимости и абсолютной непрерывности) почти не известны даже среди специалистов по предельным теоремам. Предлагаемый обзор призван заполнить эту лакуну. В нeм представлены как уже опубликованные результаты, так и новые факты.

Волчки и магнитные орбиты
Authors: Novikov Sergei Petrovich
Published: November 2020

Целый ряд направлений были начаты автором и его учениками в работах 1981-1982 гг. Одно направление - свойства замкнутых орбит на сфере $S^2$ и в группах ${S}^3$ и $\operatorname{SO}_3$ - было, однако, развито недостаточно. В данной статье мы ставим своей целью возродить обсуждение этих вопросов, сформулировать нерешeнные задачи и прояснить то, что считалось ошибочным в старых работах. Магнитные орбиты вообще в литературе обсуждались слабо. Это относится к литературе по динамическим системам и теоретической механике. В теоретической физике, как указал автору П. Г. Гриневич, похожие ситуации встретились в теории, связанной с ускорителями - протонными циклотронами. Интересно посмотреть книгу Л. Д. Ландау и Е. М. Лифшица "Теоретическая физика, т. 2: теория поля" (гл. III), где возникают ситуации, математически родственные нашим, но физика совсем другая и мы имеем реальные сильные магнитные поля.

Yataklar genel olarak, yuvarlanmalı (rulmanlar) ve kaymalı yataklar olmak üzere ikiye ayrılabilir. Rulmanlar, dişli çark, kasnak, volan vb. makine elemanları üzerinden mil veya aksa gelen yükleri karşılayabilmek için destek elemanı olarak görev yaparlar. Rulman kataloglarında, her bir rulman için verilen dinamik yük sayısı (C) değerleri, %90 güvenilir kabul edilmektedir. Daha yüksek güvenirlik istenildiğinde, ilgili standartlardan yararlanılarak seçim yapılabilir. Çalışma anında, uygun olmayan yağlama, yanlış tip rulman seçimi, kirlilik, montaj hasarları vb. nedenlerden dolayı rulman ömürleri ve güvenilirlik ciddi oranlarda azalmakta ve erken hasarlar meydana gelmektedir. İlgili ISO ve DIN standartları göz önünde bulundurularak, güvenilirlik, yağın kirlilik seviyesi, çalışma sıcaklığı, viskozitesi vb. faktörlerin rulman ömrü üzerine olan etkileri incelenmiştir.
Efficacy Of Indigenous Arbuscular Mycorrhizal Fungi And Liquid Organic Fertilizer For Promoting The Vegetative Growth Of Soybean Plants (Glycine max L.) On Ultisols
Authors: Herdy Suparmanto  , Husna Faad  , Halim
Published: December 2020

Utilization of ultisols in Southeast Sulawesi may be approached by inoculating viable arbuscular mycorrhizal fungi (AMF) exposing plant growth-promoting activities to the growth of native economical plants. This study investigated a combination of AMF and liquid organic fertilizers from coconut husks to improve the growth of soybean plants grown on ultisols as one of the potential marginal soils in the region. The coconut husk served as an abundant, cheap, yet potential source for the preparation of liquid organic fertilizers. This study used two factorial design with four treatment levels. The first factor was designed for different AMF species (10 g/pots): control (M0), Acaulospora delicata (M1), Septoglomus constrictum (M2), and Claroideoglomus etunicatum (M3) while the second factor was designed for different concentration of liquid organic fertilizer (mL/pots): control (P0), 150 mL/pots (P1), 200 mL/pots (P2), and 250 mL/pots (P3). Based on ANOVA results, the independent application of AMF species and liquid organic fertilizers gave significant results in regards to the experimental variables such as plant height, number of leaves, leaf area, and stem diameter. The best combination of treatment was observed in the treatment using Septoglomus constrictum with the concentration of liquid organic fertilizer of 250 mL (M2P3) to yield the highest growth performance of soybean plants on ultisols.

Authors: Gardiner Edward
Published: November 2020

Many people around the world are taking action to address the problems that matter to them and their community, from anti-social behaviour to unaffordable healthcare to institutional corruption. Many more people have the potential to make a difference in their community. Their collective knowledge, skills, abilities and personal attributes are the building blocks of social change. While there is a growing emphasis on the role of disciplines such as design, behavioural science and digital technology in social innovation, people need to develop and exchange a range of attributes to understand problems and implement ideas. In this article I review some of the individual and environmental factors that are predictive of creative performance and entrepreneurial success, and highlight areas of opportunity for how to help more people get involved in activities with a social benefit.

Published: November 2020

Merkez bankalarının enflasyon hedeflemesi stratejisi ya da fiyat istikrarını sağlama hedefi ile birlikte uygulanan başarılı bir mali disiplin para ve maliye politikaları arasındaki koordinasyonun iyileşmesine katkı sağlamaktadır. Buna karşılık mali baskınlığın ortaya çıkması ve merkez bankalarının bağımsızlığını zayıflatması pek çok sorunu beraberinde getirmektedir. Bu bağlamda çalışmanın amacı mali baskınlık ile merkez bankası bağımsızlığı arasındaki ilişkiyi ampirik olarak araştırmaktır. Diğer çalışmalardan farklı olarak bu çalışmada Euro bölgesine dâhil olmayan AB ülkeleri (Bulgaristan, Çekya, Danimarka, Hırvatistan, İngiltere, İsveç, Letonya, Litvanya, Macaristan, Polonya, Romanya) ve AB’ye aday statüsünde bulunan Türkiye örneklem olarak alınmıştır. 2000-2016 dönemi verileri ile yapılan panel eşbütünleşme ve nedensellik testlerinin sonuçlarına göre mali baskınlık ile merkez bankası bağımsızlığı arasında eşbütünleşme ilişkisi ve iki yönlü nedensellik ilişkisi olduğu belirlenmiştir. Dinamik en küçük kareler (DOLS) eşbütünleşme tahmincisi sonuçlarına göre, panelin genelinde mali baskınlıkta meydana gelen %1’lik artış merkez bankası bağımsızlığını %0.22 azaltmakta iken ülkelere özgü sonuçlar farklılaşmaktadır.

Death from hunger in the world may overcome the number of deaths in conventionalwar. Therefore, food should be considered a National Security core issue of anycountry. However, the concept of National Security has evolved in this directiononly with the end of the Cold War and a growing public awareness that globalchanges may exacerbate tensions related to food and water shortages. Accordingly,this paper presents a conceptual evolution of the food issue within the context ofNational Security. Brazil’s situation is contrasted to international scenarios outlinedin an attempt to earn greater attention from the Ministry of Defense regardingBrazilian agriculture due to its important role in the five expressions of nationalpower.
¿Puede generar efectos la inasistencia del apelante a la vista de la causa en el proceso laboral de la Ley n.° 29497?
Authors: Rodríguez Riojas Juan Ismael
Published: November 2020

El presente artículo desarrolla las implicancias que pueden derivar de la inasistencia del apelante a la audiencia de la vista de la causa en el marco del proceso laboral regulado por la Nueva Ley Procesal del Trabajo, Ley n.° 29497, subrayándose que la oralidad, en armonía con los demás principios, garantiza la celeridad y eficiencia en el modelo procesal laboral vigente. En ese sentido, la extensión de la oralidad, incluso en la etapa de impugnación, con el deber de la sustentación oral del recurso impugnativo, no supone una carga desproporcional o irrazonable. Siguiendo ese orden de ideas, el objetivo del desarrollo del presente artículo es ilustrar a la comunidad jurídica sobre los efectos a generarse en razón de la inasistencia, y analizar si la aplicación de los mismos supone una «inequidad de armas» en el proceso judicial laboral.

The State of Human Rights and Political Freedoms in Belarus: Was the Crisis Inevitable?
Authors:   Eurasia Institutes, Kolarzik Nina , Terzyan Aram
Published: November 2020

The rule of Alexander Lukashenko in Belarus has created one of the most resilient authoritarian regimes in post-communist Europe. Meanwhile, the turmoil triggered by the 2020 presidential election has put in the spotlight the mounting challenges facing Lukashenko’s authoritarian rule. This paper investigates the state of human rights and political freedoms in Belarus, focusing on the main rationale behind the turmoil surrounding the 2020 presidential election. It concludes that the political crisis following the elections is the unsurprising consequence of Lukashenko’s diminishing ability to maintain power or concentrate political control by preserving elite unity, controlling elections, and/or using force against opponents.
An Overview of Itu Mbon Uso Consonants
Authors: Edo Idongesit , Akpan Okokon
Published: November 2020

This study attempts a systematic description and classification of Itu Mbon Uso Consonants, using a descriptive framework. This research will provide a background study for the description of Itu Mbon Uso consonants. It aims to establish and provide a detailed study of the consonant sounds available in the Itu Mbon Uso language. Data was collected through primary and secondary sources. The trial version of the Ibadan 400 wordlist was used in data collection. In addition, there was the need to develop short sentences in the language so as to capture the pronunciation of words not found in the 400 wordlist and to show the position of each segment in words. The objective of this research is the need to develop our indigenous languages and save them from extinction, which should begin with the development of the orthography. The study revealed that they are seventeen phonemic and twenty phonetic consonants in Itu Mbon Uso with syllabic features such as aspiration and consonant processes like nasalization and palatalization. Our contribution is the provision of the consonantal inventory of the language which will act as a springboard for the eventual development of orthography for the language. The study is also important documentation of an endangered language, which had hitherto received little attention. It is recommended that research be carried out on the vowel system of the language to ensure an eventual orthography for the language.
Current Real-World Outcomes of Recurrent Kawasaki Disease
Authors: Nakada Toshimasa
Published: November 2020

Studies have shown that recurrent Kawasaki disease (KD) is a risk factor for resistance to initial intravenous immunoglobulin (IVIG) therapy and development of coronary artery lesions (CALs). However, current real-world outcomes of recurrent KD patients remain unclear. The objective of this retrospective study was to elucidate the outcomes of recurrent KD patients in the era of 2 g/kg IVIG therapy. Data were included from 201 KD patients who underwent acute-phase treatment from January 2009 to September 2020, with 184 (91.5%) receiving 2 g/kg IVIG therapy. The patients were divided into 7 with (recurrent group) and 194 without (nonrecurrent group) recurrent KD. At the first onset, the rates of initial IVIG therapy resistance (28.6% vs. 21.5%, P = 1.000), rescue therapy (14.3% vs. 14.4%, P = 1.000), and CALs (0.0% vs. 2.6%, P = 1.000) were similar between the recurrent and nonrecurrent groups. The rates of initial IVIG therapy resistance (14.3% vs. 21.5%, P = 1.000), rescue therapy (14.3% vs. 14.4%, P = 1.000), and CALs (0.0% vs. 2.6%, P = 1.000) were also similar between the recurrent group at the second onset and the nonrecurrent group at the first onset. KD recurrence may no longer be a risk factor for developing CALs in the era of 2 g/kg IVIG therapy, unless CALs appear at the initial episode.

Finalmente, se concluye que la inversión económica no está planificada y no es rentable, debido a los altos costos fijos de la tecnología de transplante de embriones, por lo que el análisis desde el enfoque de sistemas permitió desarrollar un plan de manejo sustentable acorde a las necesidades de la UPB, del productor y de los animales.
Crypto Steganography using linear algebraic equation
Authors: Mallick Pradeep Kumar , kamila N.K.
Published: November 2020

Demand of information security is increasing day by day with the exponential growth of Internet. The content of message is kept secret in cryptography, where as steganography message is embedded into the cover image. In this paper a system is developed in which cryptography and steganography are used as integrated part along with newly developed enhanced security model. In cryptography the process of encryption is carried out using symmetric block ciphers with linear algebraic equation to encrypt a message [1] and the obtained cipher text is hidden in to the cover image which makes the system highly secured. Least Significant Bit (LSB) technique is used for message hiding which replaces the least significant Bits of pixel selected to the hide the information. A large number of commercial steganographic programs use LSB as the method of choice for message hiding in 24-bit,8bit-color images, and gray scale images. It is observed from the simulation study that both methods together enhance security significantly.

Published: November 2020

Hybrid image segmentation is proposed in this paper. The input image is firstly preprocessed in order to extract the features using Discrete Wavelet Transform (DWT) .The features are then fed to Fuzzy C-means algorithm which is unsupervised. The membership function created by Fuzzy C-means (FCM) is used as a target to be fed in neural network. Then the Back Propagation Neural network (BPN) has been trained based on targets which is obtained by (FCM) and features as input data. Combining the FCM information and neural network in unsupervised manner lead us to achieve better segmentation .The proposed algorithm is tested on various Berkeley database gray level images.
Open source Software ADOPTION: an academic perspective
Authors: Satyarajan Deepika , Akre Vishwesh
Published: November 2020

Open Source Software (OSS) is defined as a computer software that is freely provided and which permits users to use, change, and improve the software, and to redistribute it in a modified or an unmodified forms. OSS is developed in a highly social online environment where developers are dispersed in space and time, but rarely interact in a face-to-face manner. Literature in this field specifies many successful OSS implementations in Academic Institutions globally. Educational Institutions have diverse opinion on the academic use of OSS. The concept of open access and the proliferation of academic blogs have broken down many barriers in the educational sector. With the reference of studies conducted in various countries such as Switzerland, USA, Australia, UK etc., it can be said that there are two distinct views on the academic acceptance of OSS. One view is in favor of the use of OSS, while the other is hesitant about OSS thinking that it could suppress the creativity of individuals. OSS represents a social dimension of Learning through a Persistent, Unified, Massively Multi-User, and Self-Organizing Virtual Environment extending beyond the traditional classroom into the universities common areas where learners build knowledge and understanding through serendipitous and collaborative exchanges both within and across subject area boundaries. The digitization of education is a relatively new phenomenon but has already transformed the education sector .Most Educational Institutions are operated on a non-profit basis and many of them are government funded. Open Source Software’s are freely available on well-known OSS Project community providers such as www.SourceForge.net and hence can be implemented in Educational Institutions at no procurement costs. This research is an attempt to examine the differences between the implementation of OSS and Proprietary software’s in Educational Institutions. Findings of this study could facilitate Universities and Educational Institutions to evaluate the options of using OSS for their Information Technology or Information Systems requirements.

Method. The authors joined closed Facebook groups and studied the factors that enhance engagement from within. This study used a mixed method: 1) the level of engagement in closed Facebook groups was coded for 274 group members over a two-month period: the number of posts, comments and ‘likes’ were counted for each participant; 2) an online survey was answered by these participants, containing demographic questions, a group importance questionnaire, an offline activity measure and a Big5 personality questionnaire. Analysis. The data were collected into Excel, with a sheet for each participant, and then transferred to SPSS for statistical analyses. Results. There is a positive relationships between engagement, group importance, and offline activity. Women and stable, older participants tended to engage more in group discussions. A partial, positive relationship between extroversion and engagement was found. Conclusion. The findings give groups’ managers and members tools to enhance higher engagement in Facebook groups, which may sustain the online community as a dynamic social group, where all members have equal rights to engage.

Introduction. This study aims to examine users’ perception biases on the use of intellectual property search systems. Particularly, the priming effect is investigated. Method. A laboratory experiment is conducted, and two supraliminal primes are utilised. Subjects are randomly assigned to three conditions, including: (1) using an easy-to-use search system as the prime, (2) using a difficult-to-use system as the prime, and (3) a control group without any primes. Analysis. Data analyses are performed in two steps. We first validate the setup of the two primes used in this study. After that, we examine the priming effect by comparing user perceptions of the target across the three conditions. Results. In general, our data analysis results indicate the existence and significance of the priming effect. Specifically, users who are primed by a difficult-to-use intellectual property search system are found to have significantly more positive perceptions of the target system as compared to those who are primed by an easy-to-use system. Conclusions. This study identifies significant priming effects in the context of intellectual property search systems.

Introduction. This study explores health information non-sharing behaviour in everyday social settings and interactions. The novelty and relevance of the study lies in the fact that it explores a common yet understudied information behaviour, as very few studies have examined information non-sharing. Method. Forty qualitative in-depth interviews were held in Flanders, the Dutch-speaking northern part of Belgium, with adults between the ages of fifty and eighty. Analysis. A contextual framework was drawn from information studies and health information and communication research, consisting of the concepts of health orientation, information avoidance, uncertainty management, to help understand health information non-sharing. Thematic analysis was employed to identify reasons for non-sharing behaviour. Results. Seven key themes or reasons emerge for health information non-sharing behaviour; health as a non-topic, avoid being labelled as ill, individual responsibility, avoid burdening others, lack of trust in others, lack of trust in the internet, and avoiding information overload. Conclusions. This study is not only more nuanced than earlier work on sharing behaviour, but also leads to new questions about outcomes of health information non-sharing. The findings further illuminate 'non-information behaviour' within information studies, while also offering insights relevant to health communication researchers and healthcare practitioners.

Introduction.This paper explores the value that academics in an information school assign to their digital files and how this relates to their personal information management and personal digital archiving practices. Method. An interpretivist qualitative approach was adopted with data from in-depth interviews and participant-led tours of their digital storage space. Analysis. The approach taken was thematic analysis. Results. Participants placed little value on their digital material beyond the value of its immediate use. They did not attach worth to their digital files for reuse by others, for sentiment, to project their identity or for the study of the development of the discipline or the study of the creative process. This was reflected in storage and file-naming practices, and the lack of curatorial activity. Conclusions. This paper is one of the first to investigate academics' personal information management and personal digital archiving practices, especially to focus on the value of digital possessions. The paper begins to uncover the importance of wider contextual factors in shaping such practices. Institutions need to do more to encourage academics to recognise the diverse types of value in the digital material they create.

Authors:   University of Sheffield, Sheffield, United Kingdom, Wilson T.D.
Published: November 2020

Introduction. The diffusion of information science research into other disciplines has not been extensively studied. This paper attempts to remedy this situation in terms of research into information behaviour. Method. A sample of papers citing three key authors (Kuhlthau, Savolainen and Wilson) was taken from Google Scholar. Analysis. The papers were categorised as being by either exporters (information science researchers publishing in other fields) or importers, researchers in other disciplines importing ideas from information science. The citations to the key authors were categorised as affirmation, negation, application, perfunctory, and review. A non-parametric test (Chi-squared) was used, where appropriate, to determine the significance of association between variables. Results. Most citing authors in the four disciplines studied were importers, suggesting that information behaviour research is making a significant impact in those disciplines. The most common citation type was the review (44% of the total), followed by perfunctory (36%). The application type of citation was most numerous in the health-related field. No negation citations were found. Conclusion. Given the limited number of papers reviewed, it is not possible to generalise. However, the review does show that information behaviour is having an impact in the four disciplines studied, and that the most significant level of impact is found in the health field.
