The Relationship Between The Characteristics Of School-Age Children And The Incidence Of Bullying At SDN 31 Bontoraja
Authors: Nuraksanita  , Fitriani  , Haerani
Published: February 2022

The incidence of bullying in schools is not something new anymore. However, until now the incident of bullying has not been handled specifically. While it is known that bullying is a trigger for acts of violence against children. Violence is one form of action in the form of physical force, threats, or certain associations with the intention to hurt and cause physical or mental injury. Bullying is defined as suppression that is carried out intentionally, aggressively, which is carried out strongly by an individual or group. There are several factors that can influence the incidence of bullying in children, including the characteristics of the child itself. The purpose of this study was to determine the relationship between the characteristics of children and the incidence of bullying at SDN 31 Bontoraja. This research method uses an analytical observational design with a Cross Sectional approach . With a total sample population of 71 and the number of samples as many as 41 people. This research uses a sampling technique, namely probability sampling using a simple random sampling technique, also called simple. In this study, the results showed that for a low level of bullying as many as 19 people and a high level of bullying as many as 22 people. And the results of the bivariate analysis using the chi-square test obtained results for the three independent variables, namely the level of age, gender, and family environment that H0 was accepted. In this study, it can be concluded that the characteristics of school-age children consisting of age, gender, and family environment have no relationship with the incidence of bullying. Parents always control their children in socializing, using electronic and print media, for example, parents taking their children to school, accompanying their children to watch television.
Cultural tourism as a tool for creating a positive image of Bulgaria in the international community
Authors: Krastev Viliyan
Published: February 2022

The article is devoted to cultural tourism as a factor in the formation of a sustainable image of Bulgaria for the outside world, while strengthening its international competitiveness. The purpose of the study is to identify the possibilities of accumulating "soft power" in Bulgaria through the use of cultural heritage in the tourism sector. For this, the advantages of the country's cultural potential are assessed to improve its international status as a political entity in the international context. The methodology is based on spatial analysis and synthesis by identifying the post-structuralist features of the Bulgarian space in the form of an image. Cultural tourism is seen as a collection of different cultural forms of human travel thanks to the valorized cultural heritage. For this purpose, the cultural potential of Bulgaria has been traced in relation to promising forms of cultural tourism. The cultural heritage of different historical periods is consistently systematized with reference to the geocultural image of the space. The reasons for the development of the national specialization of cultural tourism are substantiated: event, cultural-historical, archaeological, religious, ethnographic, culinary, urban. The priority directions in cultural tourism are presented, which form a bright positive image of Bulgaria, based on characteristic cultural stereotypes and narratives.
Transformation of the ethnic structure of the population of the regions of the Soviet Union between the 1939 and 1989 census
Authors: Manakov Andrei
Published: February 2022

Several modern trends in the ethnic transformation of the post-Soviet space were laid down in the Soviet period. The aim of the study is to assess the degree of ethnic transformation of the regions of the Soviet Union between 1939 and 1989 split into two intervals. For this, the author's methodology is used, considering the multidirectional dynamics of the proportion of the Russian population and the titular peoples of the republics and national autonomies. The scientific novelty of the research is associated with the application of this methodology in the study of the ethnic transformation of the country's regions during a significant part of the Soviet period.
As a result of the study, significant differences in ethno-demographic trends in the country in the 30s- 50s and in the 60s - 80s.of XX centuries were identified. In the first period, migrations of the Russian population to the regions of new development in Russia and to other union republics, especially to Kazakhstan, Kyrgyzstan and Ukraine were observed. In the second period, the eastern vector of migration of the Russian population began to yield to the western one — to the European Union republics. Also, a new trend began to manifest itself to a greater extent — the outflow of Russians from the republics of Transcaucasia and Central Asia. In addition, during this period, as a result of the demographic explosion, the number and share of the titular peoples of the republics of Central Asia began to grow rapidly. At the same time, in Russia and in all European republics of the Soviet Union, there was a sharp decline in natural growth. The regions of the central part of Russia, which for a long time played the role of a “demographic donor” within the borders of the entire state, suffered especially strongly from this.
The impact of ethnic and religious diversity in the Herzegovina-Neretva canton on the socio-economic situation of inhabitants in 2005-2015
Authors: Tomasz Wiskulski
Published: February 2022

The break-up of Yugoslavia at the end of the 20th century showed the importance of national and religious diversity for the peaceful existence of the region. The war in Bosnia and Herzegovina (1992-1995) and the peace that followed, showed how difficult it is to coexist in a nationally and religiously divided society. The aim of the analysis is an attempt to show the impact of ethnic and religious diversity and conflict in the area of the Herzegovina-Neretva canton in Bosnia and Herzegovina on the economic situation of its inhabitants in the analyzed period. The research was conducted based on the analysis of existing data, decision-making processes and literature analysis. The undertaken analysis confirmed that the main reasons leading to the political crisis in the studied Herzegovina-Neretva canton include the cultural, ethnic and religious mosaic. The novelty of the research undertaken is the indication of the impact that the conflict had on the economic situation of the inhabitants of the canton and its neighboring regions. Ethnic and religious mosaic and the related conflict led to an increase in unemployment and economic migrations. It had a negative impact on the level of education and contributes to the lack of clear solutions in terms of the competences of many cantonal and government services.
“Places of remembrance” in the historic-geographical narrative: Case of the East of the Baltic region
Authors: Streletsky Vladimir
Published: February 2022

The purpose of this paper is to identify the specifics of the phenomenon of historical memory in the East of the Baltic Region. This phenomenon is considered in the framework of the historical and geographical analysis of the sociocultural and political development of the Eastern Baltic states (Poland, Lithuania, Latvia, Estonia and Finland). The theoretical and methodological basis of the research is formed by the scientific concepts of cultural memory and historical memory, the theory of “realms of memory” developed by Pierre Nora, and scientific approaches in the fields of politics of memory and politics of history. Specific patterns of the politics of memory for various Eastern Baltic countries are elucidated. The main factors and major trends of the transformation of politics of memory in the East of the Baltic Region at the end of the 20th and the beginning of the 21st centuries are described. The historical experience of the politics of memory in the Eastern Baltic countries for Russia is analysed. The historical dynamics of “realms of memory” has its own internal logic of self-development, but at the same time it is closely connected with the politics of memory carried out in different countries.

Palynology of the Lower Jurassic R0nne Formation on Bornholm, eastern Denmark
Authors: Koppelhus Eva B.
Published: February 2022

Outcrop material from the Lower Jurassic R!!nne Formation on the Danish island of Bornholm, in the Baltic Sea, has been investigated palynologically. The 34 samples examined came from sections through the Munkerup, Sose Bugt and Galgel0kke Members, which amount to about 210 m in stratigraphic thickness in the type area.
The aim of this study was to reevaluate the established stratigraphy defined by Gry (1969) and Gravesen et al. (1982) and characterize the three members by means of palynomorphs. 108 taxa have been recorded of which 67 are spores, 39 are pollen grains and 7 aquatic palynomorphs. Most of these are of little biostratigraphic value but the associations and relative abundances of a small number of selected species can be used to differentiate between the members, and correlations with other sequences elsewhere in Denmark, as well as in southern Sweden (Scania), Germany and Poland are possible. The assemblages from the Munkerup and lower part of the Sose Bugt Members are referred to Lund's (1977) Pinuspolleni­tes- Trachysporites Zone and considered to be of Hettangian age. The upper part of the Sose Bugt and the Galgel(<lkke Members both correlate with Lund's (1977) unnamed zone with Cerebropollenites macro­verrucosus, now called the Cerebropollenites macroverrucosus Zone (Dybkjrer, in press) for which a Sine­murian age has previously been suggested. The Galgel0kke assemblages are more taxonomically im­poverished and poorly preserved than those from the Sose Bugt Member, and there is no palynological evidence to indicate whether they are any younger. They could represent sediments that were deposited at the same time in different environments. The palynological data on all three members of the R0nne Formation support previous environmental interpretations, indicating lacustrine to delta plain conditions of deposition.

Authors: Домнина И.Н. , Маевская Л.И.
Published: February 2022

Восстановление некрупного предпринимательства после локдаунов 2020 года становится важнейшей задачей органов власти всех уровней. Однако проблема состоит в том, что конфигурация системы поддержки малого и среднего бизнеса до сих пор опирается на методы прямого государственного финансирования. В условиях кризиса предоставление эталонного объема помощи всем без исключения регионам вполне обоснованно, но в посткризисном периоде эти меры неэффективны. В этой связи обосновывается необходимость разработки новой модели поддержки малого и среднего предпринимательства (далее – МСП), ориентирующей на переход от бюджетного распределения средств к укреплению инфраструктуры бизнеса.

Young solar-type stars are known to show frequent “superflares,” which may severely influence the habitable worlds on young planets via intense radiation and coronal mass ejections. Here we report an optical spectroscopic and photometric observation of a long-duration superflare on the young solar-type star EK Draconis (50–120 Myr age) with the Seimei telescope and Transiting Exoplanet Survey Satellite. The flare energy 2.6 × 1034 erg and white-light flare duration 2.2 hr are much larger than those of the largest solar flares, and this is the largest superflare on a solar-type star ever detected by optical spectroscopy. The Hα emission profile shows no significant line asymmetry, meaning no signature of a filament eruption, unlike the only previous detection of a superflare on this star. Also, it did not show significant line broadening, indicating that the nonthermal heating at the flare footpoints is not essential or that the footpoints are behind the limb. The time evolution and duration of the Hα flare are surprisingly almost the same as those of the white-light flare, which is different from general M-dwarf (super-)flares and solar flares. This unexpected time evolution may suggest that different radiation mechanisms than general solar flares are predominant, such as: (1) radiation from (off-limb) flare loops and (2) re-radiation via radiative back-warming, in both of which the cooling timescales of flare loops could determine the timescales of Hα and white light.
Why Do Patients With Gout Not Take Allopurinol?
Authors: Emad Yasaman , Dalbeth Nicola , Weinman John , Chalder Trudie , Petrie Keith J.
Published: February 2022

Objective.

The objectives of this study were to examine the reasons patients give for nonadherence to allopurinol and to examine differences in intentional nonadherence for patients who did and did not achieve serum urate (SU) levels at treatment target.

Methods.

Sixty-nine men with gout attending rheumatology clinics, all prescribed allopurinol for ≥ 6 months, completed the Intentional Non-Adherence Scale (INAS). Differences in the types of intentional nonadherence were analyzed between those who did and did not achieve SU at treatment target (< 0.36 mmol/L, 6 mg/dL).

Results.

The most frequently endorsed reasons for not taking their urate-lowering therapies (ULT) were because participants wanted to lead a normal life (23%) or think of themselves as a healthy person again (20%). Patients also reported not taking allopurinol as a way of testing if they really needed it (22%). Participants with SU above target endorsed significantly more INAS items as reasons for not taking their medication, had more medicine-related concerns, and were more likely to give Testing treatment as a reason for nonadherence. Participants who were younger, single, and non–New Zealand European also endorsed more reasons for not taking their allopurinol.

Conclusion.

The major reasons behind the patient’s decision not to take allopurinol relate to the desire to lead a normal life and the strategy of testing the treatment to see if they could reduce the dose without getting symptoms. These results provide some potentially modifiable targets for adherence interventions and some recommendations to clinicians about how to reframe ULT for patients in order to improve adherence.

Published: February 2022

Objective

To determine the association of physical activity (PA) and sedentary time (ST; leisure and total ST), commuting mode with hyperuricemia in a multiethnic Chinese population, and to analyze the difference between sexes.

Methods

Baseline data were analyzed from 22,094 participants from the China Multi-Ethnic Cohort study in the Yunnan region, China. PA and sedentary behavior were assessed through questionnaires. Hyperuricemia was defined as serum urate > 7.0 mg/dL among men and > 6.0 mg/dL among women. A restricted cubic spline (RCS) was created to model the possible nonlinear relationship of PA and ST with hyperuricemia. Logistic regression was used to estimate the odds ratio (OR) and 95% CI.

Results

Hyperuricemia prevalence in the observed population was 15.5% (men 25.5%, women 10.7%). Compared to those with light PA, participants with moderate-to-vigorous PA had lower odds of hyperuricemia (adjusted ORs were 0.85 [95% CI 0.77–0.94] and 0.88 [95% CI 0.79–0.97]). However, RCS showed a U-shaped nonlinear relationship between PA and hyperuricemia, and a linear relationship between hyperuricemia prevalence and increasing ST. Total ST ≥ 4 hours/day increased the risk of hyperuricemia in women but not in men. Mode of transportation revealed that sedentary behavior increased the risk of hyperuricemia, but there were inconsistent results based on sex.

Conclusion

Moderate PA may be more beneficial in reducing the risk of hyperuricemia. Reducing ST may have a greater effect on preventing hyperuricemia in females than in males.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) held its annual meeting in 2021 in an online format due to travel restrictions during the ongoing COVID-19 (coronavirus disease 2019) pandemic. The virtual meeting was attended by rheumatologists, dermatologists, representatives of biopharmaceutical companies, and patient research partners. Similar to previous years, GRAPPA's annual meeting focused on the 3 overlapping missions of education, research, and clinical care of psoriatic disease (PsD). The virtual meeting allowed a variety of different types of sessions to be held, including the trainee symposium, keynote lectures, interactive sessions (5 Meet the Experts sessions, a debate on first-line therapy, and 5 guided poster sessions), 4 workshops (trainee workshop focusing on the diagnosis of PsD, ultrasound, magnetic resonance imaging, and the International Dermatology Outcome Measures group), updates on a variety of research topics (research findings from the 2020 GRAPPA research grant awardees, 3 basic science talks, Outcome Measures in Rheumatology [OMERACT] Working Group efforts, and Collaborative Research Network progress), current "hot topics" (use of Janus kinase inhibitors, promoting diversity and inclusion in PsD, progress on the updated GRAPPA treatment recommendations, and the introduction of the Young GRAPPA member group), and the presentation of four 2021 GRAPPA grant awardees and election results. In this prologue, we introduce the papers that summarize this meeting.
Optimality and duality for $ E $-differentiable multiobjective programming problems involving $ E $-type Ⅰ functions
Authors: Abdulaleem Najeeb
Published: February 2022

In this paper, a new concept of generalized convexity is introduced for not necessarily differentiable multiobjective programming problems with \begin{document}$ E $\end{document}-differentiable functions. Namely, the concept of \begin{document}$ E $\end{document}-type Ⅰ functions is defined for \begin{document}$ E $\end{document}-differentiable multiobjective programming problem. Based on the introduced concept of generalized convexity, the sufficiency of the so-called \begin{document}$ E $\end{document}-Karush–Kuhn–Tucker optimality conditions are established for a feasible point to be an \begin{document}$ E $\end{document}-efficient or a weakly \begin{document}$ E $\end{document}-efficient solution. Further, the so-called vector Mond-Weir \begin{document}$ E $\end{document}-dual problem is defined for the considered \begin{document}$ E $\end{document}-differentiable multiobjective programming problem and several \begin{document}$ E $\end{document}-duality theorems in the sense of Mond-Weir are derived under appropriate generalized \begin{document}$ E $\end{document}-type Ⅰ functions.
Investment strategy for renewable energy and electricity service quality under different power structures
Authors: Chen Wei , Fan Jianchang , Du Hongyan , Zhong Pingsi
Published: February 2022

This paper investigates and develops an electricity supply chain with an electricity generator and electricity retailer. The electricity generator invests in renewable energy and sells the electricity to the electricity retailer; the retailer then sells the electricity to consumers according to electricity service quality. Three models are considered: the vertical Nash game, the electricity-generator Stackelberg model, and the electricity-retailer Stackelberg model. Finally, the optimal solutions under different power-structure models are compared. Certain conclusions can be drawn from the findings: (1) the highest electricity service quality and renewable energy investment are obtained in the vertical Nash game model, the electricity generator obtains more profits in the electricity-generator Stackelberg model, and the electricity retailer obtains more profits in the electricity-retailer Stackelberg model. (2) The investment in renewable energy in the electricity-generator Stackelberg model is less than that in the electricity-retailer Stackelberg model, and the investment in electricity service quality in the electricity-retailer Stackelberg model is less than that in the electricity-generator Stackelberg model (under certain conditions). (3) Both increasing the electricity service quality sensitivity and renewable energy sensitivity could increase the optimal electricity price, electricity demand, electricity service quality, renewable energy investment, and supply-chain enterprises' profit.

In the present paper, we introduce the notion of a $ \mathcal{C}^{\star} $-algebra valued bipolar metric space and prove coupled fixed point theorems. Some of the well-known outcomes in the literature are generalized and expanded by the results shown. An example and application to support our result is presented.
Wong-Zakai approximations and long term behavior of second order non-autonomous stochastic lattice dynamical systems with additive noise
Authors: Li Xintao ,   School of Mathematical Sciences, Xiamen University, Xiamen 361005, China
Published: February 2022

In this article, we investigate the Wong-Zakai approximations of a class of second order non-autonomous stochastic lattice systems with additive white noise. We first prove the existence and uniqueness of tempered pullback random attractors for the original stochastic system and its Wong-Zakai approximation. Then, we establish the upper semicontinuity of these attractors for Wong-Zakai approximations as the step-length of the Wiener shift approaches zero.

Published: February 2022

This paper considers the minimax perturbation bounds of the low-rank matrix under Ky Fan norm. We first explore the upper bounds via the best rank-$ r $ approximation $ \hat{A}_r $ of the observation matrix $ \hat{A} $. Next, the lower bounds are established by constructing special matrix groups to show the upper bounds are tight on the low-rank matrix estimation error. In addition, we derive the rate-optimal perturbation bounds for the left and right singular subspaces under Ky Fan norm $ \sin\Theta $ distance. Finally, some simulations have been carried out to support our theories.

The remora optimization algorithm (ROA) is a newly proposed metaheuristic algorithm for solving global optimization problems. In ROA, each search agent searches new space according to the position of host, which makes the algorithm suffer from the drawbacks of slow convergence rate, poor solution accuracy, and local optima for some optimization problems. To tackle these problems, this study proposes an improved ROA (IROA) by introducing a new mechanism named autonomous foraging mechanism (AFM), which is inspired from the fact that remora can also find food on its own. In AFM, each remora has a small chance to search food randomly or according to the current food position. Thus the AFM can effectively expand the search space and improve the accuracy of the solution. To substantiate the efficacy of the proposed IROA, twenty-three classical benchmark functions and ten latest CEC 2021 test functions with various types and dimensions were employed to test the performance of IROA. Compared with seven metaheuristic and six modified algorithms, the results of test functions show that the IROA has superior performance in solving these optimization problems. Moreover, the results of five representative engineering design optimization problems also reveal that the IROA has the capability to obtain the optimal results for real-world optimization problems. To sum up, these test results confirm the effectiveness of the proposed mechanism.
