Fernan Braudel's Times of the Worlds. Civilizational Sovereignty in Conservative Historiography
Authors: Kholmogorov Yegor S.
Published: May 2021

The article is devoted to the life and creative development of the great French historian and leader of the “Annales School” Fernan Braudel. The autjpr pays special attention to the conservative motives in his ideas, namely the theory of civilizational denial and non-progressist realism related to the concept of longe duree. The author comes to the conclusion that Bruadel was erroneously considered to be “globalist” or “mondialist” thinker. On the contrary, his concept of the “worlds-economies” describes closed economic and civilizational communities directed at autarchy and sovereignty. Braudel’s idea has very much in common with Oswald Spengler’s idea of interpreting borders of cultures, civilizations and worlds-economies as barely permeable. In his research Braudel always paid considerable attention to Russia viewing it as specific civilization having the tendency to “self-organize apart from Europe as an independent world-economy with its own network of connections”. Braudel considered that self-dependence of Russia was obvious, even after the Europeanization turn in the 18th century. Braudel’s “Russian Text” is considered to be one of the most profound and accurate in Western historiography. The present article is written in the free form, where historiographic analysis, biographic narrative and the author’s personal experience of Braudel’s works alternate with each other.
The Image of the Future in the Situation of the Decline of Culture: Contemporary Russia from the Perspective of O. Spengle
Authors: Zheltikova Inga V.
Published: May 2021

The concept of O. Spengler suggests that the history of any culture goes through certain stages of development, the last of which is civilization. During this period creative activity in culture is replaced by mechanical imitation and lost connection with the culture formed by the «pra-phenomenon». The author correlates Spengler’s postulates with the processes of actual social reality and comes to the conclusion that contemporary Russia is going through the stage of civilization. The article raises the question of how the future is seen in this situation. The author uses the term “image of the future”, introduced by F. Polak to understand the disinterest of modern post-war Europe in its future. Thus, the lack of interest in the future can be recognized as another characteristic of the state of civilization. The existence in contemporary Russia of distinct images of the future is an open question. Using the methods of content analysis, the author comes to the conclusion that in Russian contemporary society there exists a retrospective image of the future, focused on conservative values, hierarchy of society and its closed nature to the world. Thus, it is concluded that it is wrong to talk about complete absence of images of the future in contemporary Russia. But the nature and content of these images demonstrate the low level of interest in the future, which also indicates the transition of Russian culture to civilization.

Authors: Rodríguez Cruz Juan Carlos , Neto Luiz Bezerra , Rodríguez Parra Yanely
Published: May 2021

O trabalho aborda a relação das categorias resiliência cultural, educação, pós-modernidade e pós-verdade, onde a categoria educação trabalha em estreita colaboração com a resiliência para enfrentar os desafios de um mundo diversificado e em mudança; em que a pós-verdade é uma parte intrínseca da pós-modernidade, que gera conteúdos enganosos e onde a formação de professores resilientes é encarregada de educar para a objetividade científica. Parte de um texto platônico, o Mito da Caverna, por ser um dos primeiros textos antigos que expressa a dialética objetiva do conhecimento que transita do oculto ao não oculto, da sombra à luz, com o objetivo de se desdobrar o conteúdo do pensamento no futuro da educação e da cultura. É feita uma análise de alguns fundamentos teóricos de cunho subjetivo idealista que tem servido de base ou suporte para correntes de pensamento atuais como as chamadas notícias falsas. Por fim, trata da resiliência cultural e da formação científico-prática de professores como um processo de resistência e adaptação ao ataque da pós-verdade em um tempo de mudança e incerteza, que deu origem à pós-modernidade.

Published: May 2021

Through this study, we aimed to establish which are the main strategies that teachers use to increase pupils' interest in reading activities. It is unanimously accepted that frequent reading of texts has a beneficial effect on the harmonious development of each pupil. In order to create an inventory of examples of good practices provided by teachers for primary education, an online questionnaire was administered between June and October 2020. 219 teachers have completed the questionnaire and mentioned which strategies they use most frequently to make pupils appreciate the value of the books and to read more frequently. The study revealed several good practices that can be used by teachers or parents to motivate pupils to be more actively engaged in reading activities. These results are useful for primary school teachers who can use them to improve the strategies they use to determine pupils to read more frequently and with pleasure. Working with the books, frequent presentation of the content of some books, organizing reading clubs, visiting the school library, arranging a reading corner, and making portfolios about the content of favorite books are some of the strategies mentioned by teachers.

Published: May 2021

The present study was carried out in the municipality of Tibiri where assisted natural regeneration is the method adapted by agriculture to maintain trees for various reasons. The general objective of this study is to characterize the floristic diversity and the structure of the woody stand resulting from assisted natural regeneration. The methodology adopted for this study consisted of inventories of woody species and regenerations in crop fields by placing plots of 50m x 50m during the crop season. Thus twenty (20) plots were placed in the agrosystems according to homogeneity following an equidistance of 300m. The floristic survey made it possible to identify 19 species divided into 9 families of which the most represented are the Fabaceae (72%). The most represented species are P. reticulatum (30%), F. albida (17%) and P. africana (14%). These species also have the highest IVI values. The distribution of individuals by diameter class shows an "inverted J" shape with the shape parameter c = 1.959 (1 <C <3.6), characteristic of populations with a predominance of young or small diameter individuals. The total regeneration density is 2648 stems / ha, grouped into eleven (11) species showing good regeneration and dominated by G. senegalensis representing 61.93% of the density of the inventoried species followed by P. reticulatum (14 , 80%).

ANR is a practice that contributes to improving the woody biodiversity of the fields where it is practiced. It is not only an alternative to greening the environment, but also provides several products and services to populations.

Published: May 2021

Excessive alcohol intake is associated with pathological conditions that are detrimental. Aloe vera is a plant that possesses antimicrobial and anti-oxidant properties. This study investigated the effects of Aloe vera gel on alcohol induced hepato-nephrocellular dysfunction in rats using the specific activities of glutathione-S-transferase (GST), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT) and lactate dehydrogenase (LDH) as well as concentration of some electrolytes as indices. Six groups of male albino rats containing 5 rats each were used in the experiments. Groups A and B were administered distilled water and 50 % (v/v) alcohol for 21 days respectively. Groups C and D were administered 50 % (v/v) alcohol, while groups E and F were administered distilled water for the first 14 days, followed by co-administration (without stopping alcohol or distilled water administrations) of 125 mg and 250 mg.kg–1 body weight Aloe vera gel respectively for 7 days. The administration of Aloe vera gel extract significantly modulated serum electrolytes imbalances with concomitant lowering of ALT, AST, ALP, GGT, LDH and GST rates when compared to group B. These results suggested the restoration of alcohol induced dys-function by Aloe vera gel.

The publication adopts the SAE J3016 standard as the one that defines the level of vehicle autonomy. Gradually, the role of the driver, especially in terms of driving, will decrease, and the last 5th degree of automation will be achieved thanks to the complete elimination of the driver. Through the broadly understood research in the field of drivers' tasks (literature, information from enterprises and labor offices, face-to-face interviews), it can be stated that not all of them will be able to implement autonomous vehicles.
Reliability Estimation of a Network Structure Using Generalized Trapezoidal Fuzzy Numbers
Authors: Kumar Amit , Dhiman Pooja
Published: May 2021

Classical sets are used commonly to consider reliability. Because of the uncertainty in the data (which considered in the present paper) classical sets fail to describe the reliability accurately. Uncertainty leads to fluctuation in the actual situation of the structure. Fuzzy logic method attempts to test system reliability with the benefit of membership function. Within this context, specific problems of reasoning-based approaches are studied, explored and correlated with standard reliability approaches. In this paper Generalized Trapezoidal Fuzzy numbers (GTrFN) are used to assess the structure's fuzzy reliability. The reliability of each event is assigned with different level of satisfaction and some improved operations on the generalized trapezoidal fuzzy numbers (GTrFN) are used to calculate the fuzzy boundaries for the resultant reliability of the final event along with the degree of satisfaction. Also the results are compared to demonstrate the application of the improved operations on Generalized Trapezoidal Fuzzy Numbers (GTrFN). The obtained results converge to more precise interval values as compare to the vague fuzzy number.
Reduction of waste production during juice processing with a simultaneous creation of the new type of added-value products
Authors: Samborska Katarzyna , Barańska Alicja , Kamińska Paulina , Kamińska-Dwórznicka Anna , Jedlińska Aleksandra
Published: May 2021

The paper presents a new method for the reduction of waste production during juice processing through the reformulation of cloudy juices by ultrafiltration (UF), resulting in simultaneous production of a new type of cloudy juice of reduced sugar content. In contrast to the traditional juice production process, the final product was UF retentate. During UF, sugars were partially removed, while fibre and other macromolecular components present in a cloudy fraction, with health-promoting properties, were retained. Such treatment gives the possibility to reduce waste production during juice processing, because in the traditional approach, the cloudy fraction is usually treated as a waste after the clarification step. After UF in apple cloudy juice, the total content of soluble solids and sugars decreased from the initial values 11.0% and 10.4% to 9.2% and 8.8%, respectively; while in apple-beetroot cloudy juice, it reduced from 11.4% and 8.2% to 8.7% and 5.8%, respectively. At the same time, the cloudy fraction was retained and concentrated. The retention of soluble solids and sugars after the UF of apple juice was 66% and 67%, respectively, that is, 34% of soluble solids and 33% of the sugars were removed to the permeate. In apple-beetroot juice, 68% and 71% of soluble solids and sugars was retained, respectively.
The environmental right in the system of the Convention for the Protection of Human Rights and Fundamental Freedoms – selected aspects
Authors: Dąbrowska Anna
Published: May 2021

This paper aims to discuss the place of environmental right in the system of the 1950 European Convention – a fundamental Council of Europe treaty on protection of human rights. Interestingly, it does not explicitly guarantee the environmental right, it needs to be determined; therefore, if individuals can cite violations of this right in their complaints to the European Court of Human Rights – the authority guarding obedience to the European Convention. Analysis of the Strasbourg decisions implies the environmental right can be applied to highly diverse situations. In practice, complainants cite its infringements in connection with violations of the right to private and family life as incorporated in Article 8 of the European Convention. This does not mean, however, every time a complainant cites Article 8 of the European Convention to accuse a state of breaching their environmental rights, the European Court is going to accept such a charge.

Published: May 2021

The research aims to describe the underlying cause of students' low Creative Thinking Ability (CTA), and examine the effectiveness of online learning assisted by module in improving CTA in terms of self-efficacy. The research applied a mixed-method. The subjects were 8-grade students. The qualitative research subjects were selected purposively, generating two students for each category of low, medium, and high self-efficacy. While quantitative research used cluster sampling to classify experimental and control classes. The independent variable of the study was self-efficacy, and the dependent variable was CTA. Data collection was conducted by observation, interviews, documents, questionnaire, and test. Data was analyzed using descriptive analysis, statistical regression tests, and t-test. The results showed that the underlying cause of low CTA was in students' low and medium self-efficacy. Students with low and moderate self-efficacy highly depended on teacher help. For students with high self-efficacy, the CTA worked well. The results also revealed that the average CTA in the experimental class reached the minimum criteria of mastery learning; the average CTA of the experimental class was better than the CTA of the control class; and the effect of positive self-efficacy on CTA was 38.50% in the experimental category, showing that this learning was effective.

Vertical Accuracy of Digital Elevation Models Based on Differential Global Positioning System
Authors: Abdulhassan Aqeel A. , Naji Ahmed A. , Abbood Haqi H.
Published: May 2021

The Digital Elevation Model (DEM) has been known as a quantitative description of the surface of the Earth, which provides essential information about the terrain. DEMs are significant information sources for a number of practical applications that need surface elevation data. The open-source DEM datasets, such as the Advanced Space-borne Thermal Emission and Reflection Radiometer (ASTER), the Shuttle Radar Topography Mission (SRTM), and the Advanced Land Observing Satellite (ALOS) usually have approximately low accuracy and coarser resolution. The errors in many datasets of DEMs have already been generally examined for their importance, where their quality could be affected within different aspects, including the types of sensors, algorithms, terrain types, and other features. Ground control points (GCPs) used in this study were observed through the utilization of differential global positioning system (DGPS) with dual frequencies. Statistical indices were used to compare, evaluate, and validate the DEMs data against DGPS data. Statistical analysis of DEMs pointed out that SRTM accuracy was higher, with Root Mean Square Error (RMSE) of ±6.276m as compared to the other DEMs. ASTER showed the biggest residual error with an RMSE of ±10.241m. Nevertheless, ALOS was noticeably improved by having an RMSE of ±6.988m.

Published: May 2021

The aim of this paper is to study the combined effects of the concentration and the thermo-diffusion on the unsteady oscillation flow of an incompressible Carreau fluid through an inclined porous channel. The temperature is assumed to affect exponentially the fluid's viscosity. We studied fluid flow in an inclined channel under the non-slip condition at the wall. We used the perturbation series method to solve the nonlinear partial differential equations. Numerical results were obtained for velocity distribution, and through the graphs, it was found that the velocity of fluid has a direct relation with Soret number, Peclet number, and Grashof number, while it has a reverse variation with chemical reaction, Schmidt number, frequency of oscillation, and Froude number.

One new, 10, 11-dioxo-6,7α-erythraline epoxide (A1) and four known erythrinan alkaloids 10, 11-dioxo-erythraline (A2), erysodine (A3), 8-oxo-erythraline (A4) and erythraline (A5) were isolated from the 70% methanolic extract of stems of E. Corallodendron (Fabaceae). The isolated compounds were elucidated by exploiting 1D/2D NMR, and HR-ESI-MS analysis. The absolute configuration of A1 was determined by electronic circular dichroism (ECD). Mono Amine Oxidase inhibitory activity of the isolated alkaloids was investigated in vitro using kynuramine deamination assay on recombinant human MAO-A and B enzymes. The binding modes were predicted by molecular docking and the structure activity relationships of erythrinans were then evaluated. All isolated alkaloids demonstrated preferential activity against MAO-B. A1 displayed the highest potency and selectivity against MAO-B with IC50 of 25.18 μM, (SI >3.97). The selective inhibition exhibited by erythrinan alkaloids against MAO-B is in line with the expected biological impact of Erythrina in the treatment of neurodegenerative diseases and presents this chemical class as promising leads for managing AD and PD diseases.

Inhibition of protein disulfide isomerase (PDI) has been attempted as a promising anti-cancer strategy. However, there is still no currently available PDI inhibitors approved for clinical use. Here, we isolated seven high yield alkaloids from Stephaniae tetrandrae Radix (STR), a medical herb frequently prescribed in anti-tumor condition, and identified two potent natural PDI inhibitors, dicentrine and dicentrinone. Among the seven alkaloids isolated, dicentrinone (1), dicentrine (2), tetrandrine (4), and fangchinoline (5) could significantly reduce cell viability in a dosage dependent manner detected by MTT assay in human hepatoma cells. To examine whether the candidate compounds are potent PDI inhibitors, we performed insulin turbidity assay and found dicentrine and dicentrinone, but not tetrandrine and fangchinoline, could effectively inhibit PDI activity, with IC50 of 56.70 μM and 43.95 μM respectively. Meanwhile, dicentrine and dicentrinone failed to further reduce the cell number index when co-treated with siRNA of PDI, suggesting the compounds behave as PDI inhibitors. Furthermore, dicentrinone and dicentrine have been successfully docked to the active pocket of PDI (PDB #3UEM) by molecular docking, suggesting the existence of physical interaction between compounds and PDI. Our results suggested that dicentrine and dicentrinone may be developed into safe PDI inhibitors.

Published: May 2021

Jatroidaine A (1), a new tetranortirucallane-type triterpene, and two known analogues (2−3) were isolated from the leaves and branches of Jatropha multifida. Their structures were fully elucidated by extensive spectroscopic methods and comparison to known compounds. The absolute configuration of 1 was assigned by single-crystal X-ray diffraction analysis. All compounds were evaluated for their anti-inflammatory and thioredoxin reductase (TrxR) inhibitory activities. Unfortunately, no significant activity was observed.
Perceptions of Employability Skills of Newly Qualified Nursing Graduates from the University of Namibia

Published: May 2021

The period of transition from being a student nurse to a professional nurse remains the most traumatic and stressful period for newly qualified nursing graduates. These graduates are expected to adapt to the working environment while they are still under scrutiny to see whether they have acquired sufficient knowledge, skills and confidence to practise safe nursing care. This study aimed to determine and describe the perceptions of employers regarding the employability skills of newly qualified nursing graduates from the School of Nursing at the University of Namibia. A total of 168 nursing service managers from four public hospitals and two private hospitals were invited to participate in the study during 2019. Altogether 114 (68%) participants completed a self-administered questionnaire. The findings of this study showed a relatively low rating of 37 (32.5%) participants who had observed weak performance in the skills of newly qualified nursing graduates regarding invasive procedures and cardiopulmonary resuscitation (CPR). These skills were mostly rated as poor, fair or average. There was no association between observing poor skills with invasive procedures and the number of employees’ years of experience, ?2 (24)>= 24.070, p=0.239. Findings in this study call for well-articulated plans from nurse educators and faculty members to implement immediate actions to address the issues highlighted in this study.
Factors Influencing Patient Experience in Primary Healthcare Clinics within the eThekwini Municipality in KwaZulu-Natal
Authors: Padayachee Hope , Mutambara Emmanuel
Published: May 2021

Patient experience is seen as a fundamental measure for healthcare evaluation, which fuels the debate regarding the most relevant factors influencing patient experience. Limited empirical knowledge exists concerning the factors that influence patient experience from the users’ perspective in South Africa. This study addresses the research gap by determining the factors influencing patient experience among primary healthcare users in Waterloo, Grove-End and Stonebridge communities in the eThekwini Municipality of KwaZulu-Natal. The study is quantitative, descriptive and cross-sectional, and utilises a self-administered questionnaire that was distributed among 280 primary healthcare users. They strongly agreed (> 90%) that all the factors presented in the study are contributors to their patient experience. The factor analysis determined the relevance of the factors as perceived by the respondents. It was found that the doctor’s role (0.970), clinic cleanliness (0.943), coordination and continuity of care (0.943), and waiting time (0.914) are the most significant influencers of patient experience. Education (0.898), nurses (0.882), medication (0.854) and the quality of care (0.853) serve as moderate influencers. Access (0.745), family/friend involvement (0.722) and the physical state of the infrastructure (0.714) are mild influencers of patient experience. Patient-centred care (0.639), management effectiveness (0.637), communication (0.596) and information (0.443) were non-influencers of patient experience. User experience is multifaceted and each factor represents a varying level of influence. It is recommended that a patient-experience framework should be developed that can be linked to improvement initiatives within South Africa in an effort to support quality improvement.
Chronic Plantar Heel Pain Is Principally Associated With Waist Girth (Systemic) and Pain (Central) Factors, Not Foot Factors: A Case-Control Study

Published: May 2021

Objective

To determine the independent associations of potential clinical, symptom, physical activity, and psychological factors with chronic plantar heel pain.

Design

Case-control.

Methods

We investigated associations by comparing 220 participants with chronic (more than 3 months in duration) plantar heel pain to 100 age- and sex-matched controls, who were recruited randomly from the electoral roll. Exposures measured were waist girth, body mass index, body composition, clinical measures of foot and leg function, physical activity via accelerometry, depression and pain catastrophizing, symptoms of prolonged morning stiffness anywhere in the body, and multisite pain. Data were analyzed using multivariable conditional logistic regression.

Results

Waist girth (centimeters) (odds ratio [OR] = 1.06; 95% confidence interval [CI]: 1.03, 1.09), ankle plantar flexor strength (kilograms) (OR = 0.98; 95% CI: 0.97, 0.99), pain at multiple sites (pain at 1 other site: OR = 2.76; 95% CI: 1.29, 5.91; pain at 4 or more other sites: OR = 10.45; 95% CI: 3.66, 29.81), and pain catastrophizing status (none, some, or catastrophizer) (some: OR = 2.91; 95% CI: 1.33, 6.37; catastrophizer: OR = 6.79; 95% CI: 1.91, 24.11) were independently associated with chronic plantar heel pain. There were univariable but not independent associations with morning stiffness, first metatarsophalangeal joint extension range of motion, depression, and body mass index. There were no significant associations with physical activity or body composition (bioelectrical impedance analysis).

Conclusion

Waist girth, ankle plantar flexor strength, multisite pain, and pain catastrophizing, but not foot-specific factors, were independently associated with chronic plantar heel pain. Of these 4 factors, 3 (waist girth, multisite pain, and pain catastrophizing) were central or systemic associations. J Orthop Sports Phys Ther 2021;51(9):449–458.
