Authors: AKDAĞ Muhammet Nurullah , ZENGİN Mehmet
Published: May 2020

Bu çalışma, artan dozlarda bakır sülfat (BS; CuSO4.5H2O; %35 Cu) ve azot uygulamalarının Quality çeşidi ekmeklik buğdayda verim ve verim unsurları ile kök ve kök boğazı çürüklüğü hastalığına (KKBÇH) etkilerini tespit etmek amacıyla 2016-2017 üretim sezonunda Konya’nın Sarayönü İlçesi’nin Değirmenli Mahallesi’nde 0 ada 307 parsel numaralı bir çiftçi tarlasında yağmurlama sulamalı koşullarda yapılmıştır. Çalışmada 3 blok ve her blokta 24 parsel olmak üzere toplam 72 parsel oluşturulmuştur. Bloklara 10, 15 ve 20 kg N da-1 dozları uygulanmıştır. Ayrıca her blokta kendi içinde 4 tekerrürlü olarak 0, 0.5, 1, 2, 4 ve 6 kg BS da-1 dozları kullanılmıştır. Araştırma sonuçlarına göre, en yüksek buğday verimi (405 kg da-1) ‘15 kg N da-1 + 4 kg BS da-1’ uygulamasından alınmıştır. Ayrıca 10 kg N da-1 bloğunda 2 kg BS da-1 dozu ve üzeri dozlarda, 15 kg N da-1 ve 20 kg N da-1 bloklarında ise 4 kg BS da-1 dozu ve üzerindeki dozlarda BS uygulanan parsellerde KKBÇH’nın oluşmadığı belirlenmiştir. Uygulanan N dozlarının buğdayda verim ve verim unsurlarına etkilerine bakıldığında, en yüksek verim ve verim unsurları değerleri 15 kg N da-1 uygulamasından elde edilmiştir. Bu yüzden benzer koşullardaki buğday yetiştiriciliğinde 15 kg N da-1 ve 4 kg BS da-1 dozlarının kullanılması önerilebilir.

The Pitfalls of Christian Political Moralism: Book I of Utopia and its Augustinian Source
Authors: Burns Daniel
Published: May 2020

In depicting the Utopia's main character Raphael Hythloday, Thomas More appears to have drawn on the character Evodius in Augustine's dialogue On Free Choice. Hythloday and Evodius hold similar views on the relation between human law and the divine prohibition on homicide. Hythloday's views appear at first to be inconsistent, but Evodius's arguments for his related views can help make better sense of Hythloday's. Both characters also turn out to display similar moral-political confusions, caused by the interaction of their Christian faith with their insufficient political education, that hurt their ability to serve their country as good citizens. These confusions are typical of educated Christian citizens but not inevitable: More and Augustine each offer alternative models of more clear-sighted Christians who can serve their earthly homeland in full awareness of its imperfections.

Hindering of Cariogenic Streptococcus mutans Biofilm by Fatty Acid Array Derived from an Endophytic Arthrographis kalrae Strain
Authors: Abdel-Aziz Marwa M. , Emam Tamer , Raafat Marwa M.
Published: May 2020

Streptococcus mutans has been considered as the major etiological agent of dental caries, mostly due to its arsenal of virulence factors, including strong biofilm formation, exopolysaccharides production, and high acid production. Here, we present the antivirulence activity of fatty acids derived from the endophytic fungus Arthrographis kalrae isolated from Coriandrum sativum against Streptococcus mutans. The chemical composition of the fatty acids was analyzed by gas chromatography–mass spectrometry GC-MS and revealed nine compounds representing 99.6% of fatty acids, where unsaturated and saturated fatty acids formed 93.8% and 5.8 % respectively. Oleic and linoleic acids were the major unsaturated fatty acids. Noteworthy, the fatty acids at the concentration of 31.3 mg L–1 completely inhibited Streptococcus mutans biofilm, and water insoluble extracellular polysaccharide production in both polystyrene plates, and tooth model assay using saliva-coated hydroxyapatite discs. Inhibition of biofilm correlated significantly and positively with the inhibition of water insoluble extracellular polysaccharide (R = 1, p < 0.0001). Furthermore, Arthrographis kalrae fatty acids at a concentration of 7.8 mg L–1 exhibited acidogenesis-mitigation activity. They did not show bactericidal activity against Streptococcus mutans and cytotoxic activity against human oral fibroblast cells at the concentration used. On the other hand, saliva-coated hydroxyapatite discs treated with sub-minimum biofilm inhibitory concentration of fatty acids showed disturbed biofilm architecture with a few unequally distributed clumped matrices using fluorescence microscopy. Our findings revealed that the intracellular fatty acid arrays derived from endophytic Arthrographis kalrae could contribute to the biofilm-preventing alternatives, specifically Streptococcus mutans biofilms.

Published: May 2020

Rodent models have contributed significantly to the understanding of haematological malignancies. One important model system in this context are patient-derived xenografts (PDX). In the current study, we examined 20 acute leukaemia PDX models for growth behaviour, infiltration in haemopoietic organs and sensitivity towards cytarabine. PDX were injected intratibially (i.t.), intrasplenicaly (i.s.) or subcutaneously (s.c.) into immune compromised mice. For 18/20 models the engraftment capacity was independent of the implantation site. Two models could exclusively be propagated in one or two specific settings. The implantation site did influence tumour growth kinetics as median overall survival differed within one model depending on the injection route. The infiltration pattern was similar in i.t. and i.s. models. In contrast to the s.c. implantation, only one model displayed circulating leukaemic cells outside of the locally growing tumour mass. Cytarabine was active in all four tested models. Nevertheless, the degree of sensitivity was specific for an individual model and implantation site. In summary, all three application routes turned out to be feasible for the propagation of PDX. Nevertheless, the distinct differences between the settings highlight the need for well characterized platforms to ensure the meaningful interpretation of data generated using those powerful tools.
A New Parametric Life Distribution with Modified Bagdonavičius–Nikulin Goodness-of-Fit Test for Censored Validation, Properties, Applications, and Different Estimation Methods
Authors: Mansour Mahmoud , Rasekhi Mahdi , Ibrahim Mohamed , Aidi Khaoula , Yousof Haitham M. , Abd Elrazik Enayat
Published: May 2020

In this paper, we first study a new two parameter lifetime distribution. This distribution includes “monotone” and “non-monotone” hazard rate functions which are useful in lifetime data analysis and reliability. Some of its mathematical properties including explicit expressions for the ordinary and incomplete moments, generating function, Renyi entropy, δ-entropy, order statistics and probability weighted moments are derived. Non-Bayesian estimation methods such as the maximum likelihood, Cramer-Von-Mises, percentile estimation, and L-moments are used for estimating the model parameters. The importance and flexibility of the new distribution are illustrated by means of two applications to real data sets. Using the approach of the Bagdonavicius–Nikulin goodness-of-fit test for the right censored validation, we then propose and apply a modified chi-square goodness-of-fit test for the Burr X Weibull model. The modified goodness-of-fit statistics test is applied for the right censored real data set. Based on the censored maximum likelihood estimators on initial data, the modified goodness-of-fit test recovers the loss in information while the grouped data follows the chi-square distribution. The elements of the modified criteria tests are derived. A real data application is for validation under the uncensored scheme.
CMOS Analog AGC for Biomedical Applications
Authors: Bolaños-Pérez Ricardo , Rocha-Pérez José Miguel , Díaz-Sánchez Alejandro , Ramirez-Angulo Jaime , Tlelo-Cuautle Esteban
Published: May 2020

In this paper, we present the design of an analog Automatic Gain Control with a small silicon area and reduced power consumption using a 0.5 μ m process. The design uses a classical approach implementing the AGC system with simple blocks, such as: peak detector, difference amplifier, four-quadrant multiplier, and inversor amplifier. Those blocks were realized by using a modified Miller type OPAMP, which allows indirect compensation, while the peak detector uses a MOS diode. The AGC design is simulated using the Tanner-Eda environment and Berkeley models BSIM49 of the On-Semiconductor C5 process, and it was fabricated through the MOSIS prototyping service. The AGC system has an operation frequency of around 1 kHz, covering the range of biomedical applications, power consumption of 200 μ W, and the design occupies a silicon area of approximately 508.8 μ m × 317.7 μ m. According to the characteristics obtained at the experimental level (attack and release time), this AGC can be applied to hearing aid systems.
Photovoltaic Solar Systems in Multi-Headquarter Institutions: A Technical Implementation in Northeastern Brazil
Authors: Pinheiro Hélio Henrique Cunha , Silva Neilton Fidélis da , Branco David Alves Castelo , Pereira Márcio Giannini
Published: May 2020

The use of photovoltaic solar technology is increasingly widespread and consolidated worldwide, gaining significant interest in Brazil. Thanks to records of gradual photovoltaic system price decreases and the construction of legal frameworks favorable to their diffusion, urban and rural residential consumers, service companies, industries, and the government are progressively adhering to the use of this technology. In this context, it is important that institutions and companies with multiheadquarters discern whether it is more advantageous, from both a technical and economic point of view, to disperse photovoltaic systems throughout all of their headquarters or to centralize them in the offices presenting the best energy efficiency. The present study aims at answering this question. To this end, indicators recorded in the Institute of Education Science and Technology (IFRN)-Solar Project implemented by the Rio Grande do Norte Federal Institute of Education, Science and Technology, in Brazil, where 2 MWp of photovoltaic solar energy are installed in 19 of its 22 headquarters, were evaluated. The PVWatts Software, energy measurements at the different plant installation locations and technical performance parameters recurrent in the literature, as well as the Discounted Payback Method were used herein. The results indicate that system centralization in the best-evaluated sites (7 campi) will, in 25 years, provide a 9.07% energy supply gain, a 112.96% financial gain, and a payback reduction of 8.9 years when compared to the alternative comprising generation unit dispersion throughout the 19 campi.

Authors: Kim Hyo-Jun , Shin Ji-Hyun , Jo Jae Hun , Cho Young-Hum
Published: May 2020

Accurate measurement of air flow rate is essential in automatic building control using the variable air volume (VAV) system. In order to solve the problems of the existing air flow measurement method and improve the accuracy of air flow control, this study developed a data-based multiple regression air flow prediction model. The independent variables used in the development of the predictive model were selected as the factors used for control and monitoring when operating with variable air flow rate in the existing air conditioning system. Data collection and correlation between independent variables and air flow rate of the terminal unit were analyzed. Using the IBM SPSS statistics version 25, an air flow rate prediction model was developed using multiple regression analysis. Reliability of model was evaluated by comparing the measured airflow. The relative error of −9.3% to 10.4% is shown when comparing the estimated air flow rate by the developed model with the measured air flow rate.
Characteristics of Miscanthus Fuel by Wet Torrefaction on Fuel Upgrading and Gas Emission Behavior
Authors: Park Jae-Hyun , Choi Young-Chan , Lee Young-Joo , Kim Hyung-Taek
Published: May 2020

Biomass is a solid fuel that can be used instead of coal to address the issue of greenhouse gases. Currently, biomass is used directly in combustion or via co-combustion in coal-fired power plants. However, its use is limited due to calorific value and ash problems. In this study, wet torrefaction (WT) was carried out at various temperatures (160 °C, 180 °C, and 200 °C) and the properties of the product were evaluated. In comparison to dry torrefaction, the ash contained in biomass was extracted by an acidic solution (i.e., acetic acid) from the overreaction of the biomass. From examining the ash content of the treated WT, it was confirmed that K2O of basic ash was mainly extracted. In particular, in the case of K2O, since the main cause of combustion problems are issues such as fouling and slagging, the removed WT can be stably combusted in the boiler. Finally, the combustion and emission behaviors were evaluated by TGA-DTG and TGA-FTIR. As the fuel-N was decreased in the WT proess, the NOx in the emission gas after combustion was lower than that of raw miscanthus, and SO2 showed a similar value. As a result, it was confirmed that the WT sample is an advanced fuel in terms of fuel upgrading, alkali minerals, and NOx emission compared to raw miscanthus.
Performance Improvement of a Hydraulic Active/Passive Heave Compensation Winch Using Semi Secondary Motor Control: Experimental and Numerical Verification
Authors: Moslått Geir-Arne , Rygaard Hansen Michael , Padovani Damiano
Published: May 2020

In this paper, a newly developed controller for active heave compensated offshore cranes is compared with state-of-the-art control methods. The comparison is divided into a numerical part on stability margins as well as operational windows and an experimental validation of the expected performance improvement based on a full-scale testing on site with a crane rated to 250 metric tons. Such a crane represents the typical target for the new control method using a combination of active and passive hydraulic actuation on the main winch. The active hydraulic actuation is a hydrostatic transmission with variable-displacement pumps and variable-displacement motors. The new controller employs feedforward control of the motors’ displacement so that the window of operation is increased and, simultaneously, oscillations in the system are markedly reduced.
Climate Change and Green Sea Turtle Sex Ratio—Preventing Possible Extinction
Authors: Blechschmidt Jana , Wittmann Meike J. , Blüml Chantal
Published: May 2020

Climate change poses a threat to species with temperature-dependent sex determination (TSD). A recent study on green sea turtles (Chelonia mydas) at the northern Great Barrier Reef (GBR) showed a highly female-skewed sex ratio with almost all juvenile turtles being female. This shortage of males might eventually cause population extinction, unless rapid evolutionary rescue, migration, range shifts, or conservation efforts ensure a sufficient number of males. We built a stochastic individual-based model inspired by C. mydas but potentially transferrable to other species with TSD. Pivotal temperature, nest depth, and shading were evolvable traits. Additionally, we considered the effect of crossbreeding between northern and southern GBR, nest site philopatry, and conservation efforts. Among the evolvable traits, nest depth was the most likely to rescue the population, but even here the warmer climate change scenarios led to extinction. We expected turtles to choose colder beaches under rising temperatures, but surprisingly, nest site philopatry did not improve persistence. Conservation efforts promoted population survival and did not preclude trait evolution. Although extra information is needed to make reliable predictions for the fate of green sea turtles, our results illustrate how evolution can shape the fate of long lived, vulnerable species in the face of climate change.
Oviductal Extracellular Vesicles Improve Post-Thaw Sperm Function in Red Wolves and Cheetahs

Published: May 2020

Artificial insemination (AI) is a valuable tool for ex situ wildlife conservation, allowing the re-infusion and dissemination of genetic material, even after death of the donor. However, the application of AI to species conservation is still limited, due mainly to the poor survival of cryopreserved sperm. Recent work demonstrated that oviductal extracellular vesicles (oEVs) improved cat sperm motility and reduced premature acrosomal exocytosis. Here, we build on these findings by describing the protein content of dog and cat oEVs and investigating whether the incubation of cryopreserved red wolf and cheetah sperm with oEVs during thawing improves sperm function. Both red wolf and cheetah sperm thawed with dog and cat oEVs, respectively, had more intact acrosomes than the non-EV controls. Moreover, red wolf sperm thawed in the presence of dog oEVs better maintained sperm motility over time (>15%) though such an improvement was not observed in cheetah sperm. Our work demonstrates that dog and cat oEVs carry proteins important for sperm function and improve post-thaw motility and/or acrosome integrity of red wolf and cheetah sperm in vitro. The findings show how oEVs can be a valuable tool for improving the success of AI with cryopreserved sperm in threatened species.
Natural Cyanobacterial Polymer-Based Coating as a Preventive Strategy to Avoid Catheter-Associated Urinary Tract Infections
Authors: Costa Bruna , Mota Rita , Tamagnini Paula , L. Martins M. Cristina , Costa Fabíola
Published: May 2020

Catheter-associated urinary tract infections (CAUTIs) represent about 40% of all healthcare-associated infections. Herein, the authors report the further development of an infection preventive anti-adhesive coating (CyanoCoating) meant for urinary catheters, and based on a natural polymer released by a marine cyanobacterium. CyanoCoating performance was assessed against relevant CAUTI etiological agents, namely Escherichia coli, Proteus mirabilis, Klebsiella pneumoniae, methicillin resistant Staphylococcus aureus (MRSA), and Candida albicans in the presence of culture medium or artificial urine, and under biofilm promoting settings. CyanoCoating displayed a broad anti-adhesive efficiency against all the uropathogens tested (68–95%), even in the presence of artificial urine (58–100%) with exception of P. mirabilis in the latter condition. Under biofilm-promoting settings, CyanoCoating reduced biofilm formation by E. coli, P. mirabilis, and C. albicans (30–60%). In addition, CyanoCoating prevented large crystals encrustation, and its sterilization with ethylene oxide did not impact the coating stability. Therefore, CyanoCoating constitutes a step forward for the implementation of antibiotic-free alternative strategies to fight CAUTIs.

Authors: Pollice Fabio , Rinella Antonella , Epifani Federica , Miggiano Patrizia
Published: May 2020

This paper reports on the experience of the first Placetelling® training course in Santo Antão and Santiago, Cape Verde, promoted by Società Geografica Italiana and Fondazione Lelio e Lisli Basso. Placetelling® is a particular type of storytelling of places that promotes local development and helps to develop a sense of identity and belonging among the members of the community. Indeed, Placetelling® supports local communities to become directly engaged in the preservation of their common legacy in order to transmit it to coming generations. Tourism is the field where Placetelling® can best express its potential. This is particularly true for what concerns tourism to islands. The paper shows the first results of what we can define as a “maieutic reworking of local heritage” in Cape Verde, through the sharing of narrative and symbolic artifacts. Special attention will be dedicated to some crucial issues: The involvement of stakeholders through the lenses of empowerment, the discrepancies between how sense of identity is perceived by the locals and how it is communicated to tourists, and how and to what extent Placetelling® can change stakeholders’ awareness of their own cultural heritage.
Activators of Airline Customers’ Sense of Moral Obligation to Engage in Pro-Social Behaviors: Impact of CSR in the Korean Marketplace
Authors: Han Heesup , Chi Xiaoting , Kim Chang-Sik , Ryu Hyungseo Bobby
Published: May 2020

This study was designed to better comprehend airline customers’ purchase and pay intention formation by involving perceived airline corporate social responsibility (CSR), emotional factors, volitional factors, moral obligation, and brand involvement as key concepts. A survey methodology with quantitative data analysis was used. Our empirical results revealed that perceived CSR contributed to eliciting positive and negative emotions, brand attitude, and social norm. These variables significantly activated a sense of obligation to take pro-social actions. In addition, brand involvement acted as a significant moderator in the moral obligation and pay intention relationship. The adequateness of the higher-order structure of perceived CSR was verified.
A Three Methods Proactive Improvement Model for Buildings Construction Processes
Authors: Banawi Abdul-Aziz , Besné Alia , Fonseca David , Ferrandiz Jose
Published: May 2020

This paper proposes a proactive model to improve the overall performance of construction processes. The main advantage is that potential waste and associate impacts could be identified in the early stages of a project before the construction phase. To accomplish that, the model combines three methods; Lean-to identify waste, Green to assess environmental impact, and Six-Sigma to measure and improve process performance (LG6). The LG6 model helps in evaluating processes one step at a time, identifying consumed resources, analyzing the environmental performance of all steps as well as highlighting generated impacts, applying improving alternatives if needed, and measuring process performance for evaluation. The functionality of LG6 is illustrated through a case study of woodpiles installation. In this case study, the LG6 model identified four steps out of eight that are considered potential waste or (non-value-added steps) according to the Lean principles. As a result, the LG6 model helped in reducing impact by 9% and expenses by 1%. The LG6 model can help to improve the performance of construction processes and reduces unnecessary waste.

Mídias, efeitos de sentido e práticas de leitura e escrita: o que nos contam as narrativas digitais?
Authors: Rodrigues Alessandra
Published: May 2020

As histórias digitais, ou narrativas digitais, são aquelas construídas com e veiculadas por meio de recursos multi e hipermidiáticos. Por sua natureza multimodal e multissemiótica, essas narrativas unem a tradição humana de contar e ler histórias à contemporaneidade das tecnologias digitais; entrelaçam o antigo e o novo, o vivido e o devir num presente que desdobra o (im)possível preenchendo-o de significações. Assim, as novas mídias vêm alterando e, muitas vezes, ampliando as possibilidades discursivas das narrativas clássicas. Os efeitos de sentido possíveis advêm, nas narrativas digitais, de múltiplas semioses e a própria função-autor passa a existir em outro contexto discursivo (mais fluido e permeável à coautoria). Nesse cenário, este artigo volta-se à exploração das múltiplas possibilidades de leitura e escritura oferecidas pelas narrativas digitais, buscando apresentar os desdobramentos que essa nova forma de narrar pode trazer ao processo de criação de sentidos e construção de multiletramentos, tanto pelo autor quanto pelo leitor.

Conclusion of the 1:500 000 mapping project in the Caledonian fold belt in North-East Greenland
Authors: Henriksen Niels
Published: May 2020

The second and last field season of the mapping project in the southern part of North-East Greenland (72°–75°N) was carried out in 1998 with full accomplishment of all planned goals. The general overview mapping of the East Greenland Caledonian fold belt has now been completed, in total covering a stretch of more than 1300 km between latitudes 70°N and c. 81°30´N (Fig. 1). The Survey’s systematic regional 1:500 000 mapping programme in the East Greenland Caledonides started with mapping in the Scoresby Sund region (70°–72°N) in 1968, and in the course of 13 field seasons spread over 30 years has involved more than 50 geologists for one or more field seasons each; several Survey geologists have participated in all 13 field seasons. The mapping of the Caledonian fold belt and the adjacent pre- and post-Caledonian rocks will be presented on five 1:500 000 map sheets of which three are already published and a fourth is under compilation. The scientific results are documented in numerous publications both in international journals and in the Survey’s own Bulletins and Reports. Review articles on various parts of the East Greenland Caledonian fold belt include those of Haller (1971), Henriksen & Higgins (1976), Higgins & Phillips (1979), Henriksen (1985, 1986), Hurst et al. (1985), Peel (1985), Peel & Sønderholm (1991), Higgins (1994) and Jepsen et al. (1994). Preliminary results of the 1997 and 1998 field work have been published in Survey reports (Higgins & Frederiksen 1998, 1999), and are summarised by Henriksen (1998) and in this article.
Ketilidian structure and the rapakivi suite between Lindenow Fjord and Kap Farvel, South-East Greenland
Authors: Chadwick Brian , Garde Adam A. , Grocott John , McCaffrey Ken J.W. , Hamilton Mike A.
Published: May 2020

The southern tip of Greenland is underlain by the Palaeoproterozoic Ketilidian orogen (e.g. Chadwick & Garde 1996; Garde et al. 1998a). Field investigations in the summer of 1999 were focused on the structure of migmatites (metatexites) and garnetiferous granites (diatexites) of the Pelite Zone in the coastal region of South-East Greenland between Lindenow Fjord and Kap Farvel (Figs 1, 2). Here, we first address the tectonic evolution in the Pelite Zone in that region and its correlation with that in the Psammite Zone further north. Then, the structure and intrusive relationships of the rapakivi suite in the Pelite Zone are discussed, including particular reference to the interpretation of the controversial outcrop on Qernertoq (Figs 2, 8). Studies of the structure of the north-eastern part of the Julianehåb batholith around Qulleq were continued briefly from 1998 but are not addressed here (Fig. 1; Garde et al. 1999). The field study was keyed to an interpretation of the Ketilidian orogen as a whole, including controls of rates of thermal and tectonic processes in convergent settings. Earlier Survey field work (project SUPRASYD, 1992–1996) had as its principal target an evaluation of the economic potential of the orogen (Nielsen et al. 1993). Ensuing plate-tectonic studies were mainly funded in 1997–1998 by Danish research foundations and in 1999 by the Natural Environment Research Council, UK. The five-week programme in 1999 was seriously disrupted by bad weather, common in this part of Greenland, and our objectives were only just achieved. Telestation Prins Christian Sund was the base for our operations (Fig. 2), which were flown with a small helicopter (Hughes MD-500).

The Isukasia region of southern West Greenland contains the Earth’s oldest known supracrustal rocks (the c. 3.8–3.7 Ga Isua greenstone belt: Appel et al. 1998) and well-preserved mafic dyke swarms (Inaluk and Tarssartôq dykes: Nutman et al. 1983). This report describes field investigations of the dykes carried out in 1999 as part of the Isua Multidisciplinary Research Project, and summarises current knowledge of the dykes. The project was initiated in 1997 with the aim of coordinating a detailed reinvestigation of this geologically important region. Fifteen members of the group were involved in field work in 1999 and this article represents only one aspect of the work.

We consider two frequently encountered problems in the simulation/modernization of the communication network related to the construction of a graph of the communication network that meets certain conditions. These problems concern the optimal topology of the communication network graph. The sum of the weights of the edges of the projected graph is considered as the target function. As restrictions-achievement by the indicator of stability of a communication network of some set threshold value. Heuristic algorithms for solving these problems are proposed. The question of uniqueness of the solution of the set tasks is investigated. A positive result of solving the problem was obtained and sufficient conditions of uniqueness were found. The research and development of appropriate software are of practical importance in the design of real communication networks.

Features of evaluating the management effectiveness of regional socio-economic system from the standpoint of control theory
Authors: Averchenkova Elena E.
Published: May 2020

The concept of “efficiency” is specified in relation to the developed control system of the regional socio-economic system as the productivity of management decisions that ensure the achievement of the target level of indicators of National projects of the Russian Federation. From the point of view of control theory, performance evaluation of the decision of problems of management from evaluating the performance of the regulation system of regional socio-economic system primarily on the emergence of governors and disturbances. A criterion for the effectiveness of managing the regional socio-economic system as a function of the maximum from the managing influence of National projects of the Russian Federation is introduced. The criterion for evaluating the speed of the regional socio-economic system regulation system in response to the appearance of controlling and disturbing influences is introduced as a concept of the effectiveness of solving the problems of managing the regional socio-economic system, which is determined by the system’s ability to adjust external influence and “return” to a given target development program. To assess the behavior of the regional socio-economic system management system in the transition mode, dynamic quality indicators are used, i.e. numerical estimates of the speed of the regional socio-economic system regulation system in response to the appearance of controlling and disturbing influences, such as the time of the transition process in the regional socio-economic system control system and the time of setting the target value of indicators of National projects of the Russian Federation.

Statistical Power and Precision of Experimental Studies Originated in the Republic of Turkey from 2010 to 2020: Current Practices and Some Recommendations
Authors: Bulus Metin , Koyuncu Ilhan
Published: May 2020

This study systematically reviews randomly selected 155 experimental studies in education field originated in the Republic of Turkey between 2010 and 2020. Indiscriminate choice of sample size in recent publications prompted us to evaluate their statistical power and precision. First, above and beyond our review, we could not identify any large-scale experiments such as cluster-randomized or multi-site randomized trials, which overcome shortcomings of small-scale experiments, better suit to the organizational structure of the education field, nevertheless require far greater effort and financial resources. Second, none of the small-scale experiments has reported or conducted ex-ante power analysis. Third, results indicate that studies are sufficiently powered to detect medium effects and above (Cohen’s d ≥ 0.50), however they are under-powered to detect small effects (Cohen’s d ≤ 0.20). Trends in the past ten years indicate precision remained unchanged. We made several recommendations to increase the precision of experimental designs and improve their evidential values: Determine sample size prior to an experiment with power analysis routine, randomize subjects / clusters to obtain unbiased estimates, collect pre-test information and other relevant covariates, adjust for baseline differences beyond covariate control, document attrition, report standardized treatment effect and standardized variance parameters. Findings should be interpreted considering minimum effects in education that are relevant to education policy and practice.

Published: May 2020

Aggressive behavior poses a serious problem to medical staff. It has nu­merous consequences for the employees: they may experience anger, helplessness and even burnout, which ultimately affects the therapeu­tic process in a negative way. To reduce these negative consequences, a number of solutions are put forward, including training to prevent aggression. The content and programs of this type of training remain open, however, the literature recommends focusing on issues related to preventing the occurrence of aggressive behavior. The training is intended to provide the staff with adequate knowledge of how to deal with the aggressive behavior of patients, although this is not the only effect. It also affects the attitudes and sense of self-efficacy of partici­pants. The effectiveness of the training in this area is measurable. Ap­propriate tools are used to this end, provided by the trainers to the trainees. However, one should take into account the aspects of inter­cultural differences, such as different training systems, principles of patient care or education, which may condition the effects and changes resulting from training to prevent aggression.
Biblical Aspects of Economic Literature
Authors: Olshanska Olena
Published: May 2020

The biblical aspects in Ukrainian economic literature of the 20th and 21st century and its preconditions in European economic litera­ture have been examined. The economic theory has been rethought in the context of Christian economic ethics. The 21st century is, in a way, a result of spirituality of the previous generations, and most of all Christian spirituality. A number of socio-economic researches (such as labor processes, the study of wealth and poverty features) have shown that within the existing paradigm of science it is almost impos­sible to explain their nature and patterns of operation. The develop­ment of Christian economic ethics may be just the impetus not only for fairly significant change in economic thinking, but also for the further development of public opinion in general.
