Authors: Sharifi Ali , Alizadeh Kamal
Published: May 2020

Background: Chronic kidney disease is one of the most common diseases. The early diagnosis of this disease will reduce the length of treatment and decrease high medical costs. In recent years, the use of computer techniques in data mining and intelligent algorithms has accelerated the early diagnosis of this disease. One of the intelligent methods to diagnose this disease is artificial intelligence networks. Objectives: This study aimed to investigate the diagnosis of chronic kidney disease using an artificial intelligence network based on the multilayer perceptron method. Methods: The data of laboratory samples were collected from 140 healthy people and patients with chronic kidney disease. After preprocessing and normalization, the data were given to a multilayer perceptron and the accuracy of disease diagnosis was evaluated. All analyses were performed using MATLAB software. Results: The simulation showed a 98% accuracy of diagnosis using the proposed model. Conclusions: The results of real data suggested that the proposed system was more effective and faster than other methods in the diagnosis of acute kidney disease and it can be used as a physician assistant tool in clinical practice. In addition, it can be a cost-effective method for patients.
Assessing the relationship between cyber and traditional forms of bullying and sexual harassment: Stepping stones or displacement?
Authors: Walters Glenn D. , Espelage Dorothy L.
Published: May 2020

The purpose of this study was to determine whether cyberbullying and cyber-sexual harassment perpetration serve as antecedents or stepping stones to traditional bullying and sexual harassment, or whether traditional bullying and sexual harassment victimization encourage displacement in the form of anonymous aggressive activities like cyberbullying and cyber-sexual harassment. This research question was evaluated in a sample of 2,039 (52% female) high school students from the Illinois Study of Bullying and Sexual Violence (ISBSV) using two waves of longitudinal data. Two hypotheses were tested in two separate analyses, using bullying and cyberbullying data in one analysis, and sexual harassment and cyber-sexual harassment data in the other analysis. The stepping-stone hypothesis predicted that children would use the anonymity of cyber-bullying/harassment as a stepping stone or learning curve toward eventual involvement in face-to-face bullying/harassment. The displacement hypothesis, by contrast, held that children victimized face-to-face with traditional forms of bullying/harassment would seek release from their victimization by engaging in the largely anonymous activities of cyberbullying and cyber-sexual harassment. In both the bullying and harassment analyses, the pathway running from traditional bullying/harassment victimization to cyber-bullying/harassment perpetration proved significant, consistent with the displacement hypothesis. The pathway running from cyber aggression to traditional aggression failed to achieve significance in both the bullying and harassment analyses, providing no support for the stepping-stone hypothesis. These results imply that anonymity plays an important role in linking traditional and cyber forms of bullying and harassment.
Two dimensions of problematic smartphone use mediate the relationship between fear of missing out and emotional well-being

Published: May 2020

It has been shown that both fear of missing out (FoMO) and problematic (i.e., excessive) smartphone use (PSU) are negatively associated with indicators of emotional well-being. Moreover, FoMO has been found to be a key predictor of PSU. This suggests that PSU may mediate the relation between FoMO and decreased emotional well-being but this pathway has never been tested. Moreover, in most studies on PSU, the multidimensional nature of this construct has been ignored. The aim of the present study was to address these gaps by directly testing the mediating role of (subdimensions of) PSU in the association between FoMO and emotional well-being. We conducted a cross-sectional study with Estonian participants (n = 426). Using a simple mediation analysis, we found that PSU partially mediated the relationship between FoMO and decreased emotional well-being. Using a parallel mediation analysis, we found that two specific dimensions of PSU were significant mediators of the relationship between FoMO and decreased emotional well-being: Cyberspace-oriented Relations and Physical Symptoms. This suggests that the negative relationship between FoMO and decreased emotional well-being is due to FoMO stimulating (a) online relationships at the cost of offline interactions and (b) Physical symptoms associated with excessive smartphone use. Overall, this study provides a fine-grained analysis of the relationship between FoMO, PSU and emotional well-being.
Facebook intensity, social network support, stability and satisfaction in long-distance and geographically-close romantic relationships: A test of a mediation model
Authors: Billedo Cherrie Joy , Kerkhof Peter , Finkenauer Catrin
Published: May 2020

The impetus for this study is the proposition that social network sites (SNSs), like Facebook, can be beneficial for romantic relationships via network support functions. This study investigated a model which proposes that the use of Facebook predicts relationship support from Facebook connections, and this, in turn, predicts relationship stability and satisfaction in romantic relationships. This mediation model was tested on data gathered via an online survey among individuals who use Facebook, who are in long-distance (LDRR, n = 142) and geographically-close romantic relationships (GCRR, n = 314). GCRR participants reported higher levels of Facebook intensity and relationship support, as well as perceived relationship stability and satisfaction than participants in LDRR. Moreover, the results indicated that Facebook intensity predicted higher access to Facebook relationship support in LDRR and GCRR which, in turn, predicted perceived relationship stability and satisfaction in LDRR; and only perceived relationship satisfaction in GCRR. However, Facebook intensity had direct negative impacts on relationship satisfaction in GCRR, and on perceived relationship stability in LDRR. Facebook intensity and Facebook relationship support were not associated with relationship stability in GCRR. This demonstrates the relative importance of SNSs, such as Facebook, in relationship stability for those in LDRR.
A content analysis of teen-favored celebrities' posts on social networking sites: Implications for parasocial relationships and fame-valuation
Authors: Eyal Keren , Te'eni-Harari Tali , Katz Keshet
Published: May 2020

The aspiration of young people for fame – a wide public recognition – has risen in recent years. This fame-valuation is a concern for scholars, educators, and parents as it has been linked with teen self-focused aspirations, narcissism, and materialism. This rise in the value of fame has been linked to two trends: teens' increased attraction to celebrities and their use of social networking sites (SNSs). SNSs have changed the landscape of celebrity media presence compared to traditional media and enable a shift in balance between a professional and personal focus in the celebrity's brand image. Such a balance might have implications for the relationships audiences form with celebrities and, by extension, for adolescent fame-valuation. The current study examines the SNS (Facebook and Instagram) posts of teen-favored celebrities in order to map the characteristics of the messages to which adolescents are heavily exposed, that might reinforce their fascination with fame. The study is based on a content analysis of 1,075 posts by 24 teen-favored local and foreign celebrities in Israel. The study finds that celebrities' SNS posts lack depth in personal self-disclosure and are rather strongly focused on their professional lives – job-related activities, achievements, and self-promotion. Though SNSs present limited gatekeeping restrictions, celebrities choose to present a controlled image of themselves that is unprovocative, as evident in their promoted values, exhibited lifestyle, and physical representation.

Published: May 2020

A new species, Cryptomonas uralensis Martynenko, Gusev, Kulizin & Guseva sp. nov., is described from western slopes of the Ural Mountains (Russia) based on morphological and molecular data. Phylogenetic relationships inferred from nuclear SSU and LSU rDNA sequences show that the new species forms a clade with C. tetrapyrenoidosa Skuja emend. Hoef-Emden & Melkonian. Comparison of secondary structures of nuclear rDNA ITS2, including analysis of Compensatory Base Changes (CBC), confirms the separation between C. uralensis sp. nov. and C. tetrapyrenoidosa. Cell morphology and sizes of C. uralensis sp. nov. are very similar to C. tetrapyrenoidosa and C. pyrenoidifera, and C. uralensis sp. nov. may thus represent a species that can only be reliably identified using molecular data.

Published: May 2020

A pesquisa intitulada “A vida em Forma de História: tempos/lugares de experiência” objetivou tecer significações de ordem teórico-metodológica a respeito da pesquisa biográfico narrativa mediante produção da história de vida de uma destacada educadora/pesquisadora do Rio Grande do Sul, Brasil. Portanto, essa vida em forma de história apresenta-se, neste texto, como rico material para, ao modelar eventos vividos, evidenciar dimensões relativas a tempos/lugares experienciais constituintes dessa história como elementos compreensivos caros à pesquisa (auto)biográfica. O circuito narrativo, constituído pela palavra dada e escuta atenta, forneceu elementos analíticos para a busca desse desiderato. No processo de análise, mediante Compreensão Cênica, buscamos apreender os sentidos que lugares e momentos vivenciados, narrados reflexivamente, ocupam no decorrer dessa história. É pela reflexão, empreendida no seio do circuito narrativo, que as vivências evoluem em experiências significativas, formadoras, portanto, via uma história singular e, ao mesmo tempo plural, desde que busca construir significações do vivido em dado e datado contexto sócio-histórico. A pesquisa (auto)biográfica opera, assim, histórias de vida que representam, além de um produto, nesse caso, a vida de uma destacada educadora sul-rio-grandense em forma de história, uma opção teórico-metodológica que inclui dimensões formativas da sensibilidade humana em processo de significação de identidades narrativas. Assim, ao mesmo tempo em que homenageamos uma vida, o presente artigo tem como escopo iluminar oportunidades que a pesquisa em histórias de vida proporciona pela reflexão do narrado, possibilitando compreensões a respeito de modos pelos quais o sujeito autobiográfico se (re)inventa: no presente pela rememoração do passado, projetando-se na produção, presente/futura, de uma aprendizagem mediada por uma história composta por um conjunto de experiências vividas em tempos e lugares biográfico narrativos.

Published: May 2020

A trial was conducted to evaluate the production of earthworm meal from Eisenia fetida as a tool for the management of manure. A completely randomized design was used. The treatments were: 100% bovine manure (T1), 100% equine manure (T2) and 100% capybara manure (T3). Each treatment had five replications. A total of 50 adult and containing clitellum earthworms (Eisenia fetida) were inoculated in each experimental unity. The following analyses were performed: total nitrogen, crude protein, total phosphorus, potassium and total calcium. The results showed that the production of earthworm meal is an important tool for the management of different manure and it does not present any limitation of environmental nature. The substrates bovine manure, equine manure and capybara manure result in an earthworm meal containing a high content of crude protein. The proteic and mineral composition of earthworm meal are dependent on the quality and form of storage of the manure. The proper planning of the animal production system must contemplate an adequate place for the storage of the manure in order to maintain the quality of the substrate provided to the earthworms.

This research aimed to analyze and evaluate compliance of social and environmental information disclosed in sustainability reports in 2013 by Brazilian companies in the G3 A+ application level of the Global Reporting Initiative (GRI) organization. The methods approach was descriptive, utilizing performance indicators collected from the reports. GRI classifies performance indicators in aspects and then further into categories, which were used as score in order to compare results between reports. The firms were selected by utilizing the Índice de Sustentabilidade Empresarial – ISE (Corporate Sustainability Index) from BM&F Bovespa, which served as a filter for good business practices. Results show that, considering G3 A+ model, six out of nine companies disclosed according to what was proposed by GRI. Thus, three out of nine firms did not disclose the indicators suggested by the model. These results, when compared with previous research, shows that there was an improvement in the amount of disclosure contained in sustainability reports.

In this work, aluminum net crafted (recycled) were used as TiO2 support for the treatment of textile dye Remazol golden yellow (RGY 150). The immobilization of 200mg of TiO2 was accomplished after aluminum net calcination. The following experiments were carried out in a photocatalytic bench reactor: preliminary tests, a 23 factorial experimental design with best system and the degradation kinetic in systems with TiO2 supported on aluminum net.It was observed characteristic peaks of aluminum and TiO2 (anatase and rutile) by XRD and the catalyst film formation was verified by SEM. The system UV/H2O2/TiO2 performed higher efficiency, with 99% of dye degradation in 50 minutes, followed by the system UV/H2O2/TiO2sp with 93% of dye degradation. Whereas the supported catalyst presents execution advantages and high degradation rates, the factorial design was realized for this system, displaying best degradation (100% degradation in 35 minutes). It was obtained k = 0.114 min-1 and R² = 0.994 in a pseudo-first-order model adjustment system. The use of artificial neural network was proven to be efficient to predict the degradation of a textile dye, with an absolute error of 0.0181. After treatment, there was a decrease of dye toxicity.

Surface runoff estimate in urbanized area from the Rangel Stream basin at São Sebastião do Paraíso/MG
Authors: Almeida Amanda Francieli de , Okawa Cristhiane Michiko Passos
Published: May 2020

Urban growth generates impacts over land usage and may alter the hydrological systems of a microbasin. The unregularized occupation impermeabilizes the soil and increase the volume and velocity of superficial runoff. Thus, inundation, flood and overflow occur in urban areas.  In this context, this work’s objective was to quantify the impact of soil impermeabilization over the surface runoff coefficient in the microbasin of the Liso stream at São Sebastião do Paraíso county, Minas Gerais. Google Earth satellite images were used for the identification and determination of occupied urban areas, and ArcGis 10.4 software was utilized for letter elaboration, which determined the permeable areas. It was taken as hypothesis that the surface runoff coefficient is equal to one in impermeabilized areas. In addition, green areas and unoccupied allotments were considered as permeable areas. In order to determine the impermeabilized area, the permeable area was subtracted from the total area. The surface runoff coefficient was estimated as the relation between the impermeabilized area and the total urbanized area. The results have demonstrated that the urbanized area located in the microbasin grew 44,47% in ten years. Therefore, the estimate of surface runoff coefficient utilized in this paper can be a good alternative for city halls to analyze the urban growth and aid in the circumscription of residential areas or green areas, since it is a simple method which requires data easily generated through maps.

Published: May 2020

One of the main problems in the development of hydrological studies is the scarcity of measured data. In Brazil, because of its great water availability, and due to its territorial extension, the costs of implementing and maintaining hydrometric stations is a challenge, compromising hydrological monitoring and data collection. Therefore, developing methods that contribute to the estimation and transfer of information is essential for better integrated management of water resources, highlighting the importance of maximum streamflow data on issues such as flood mitigation. In order to solve this problem, streamflow regionalization models appear as tools to estimate hydrological data in ungauged sites, that is, it allows the transfer of measured or simulated information between homogeneous basins. In view of this, this article has the objective of investigate and describe the main methodologies developed and disseminated in the literature on hydrological regionalization, especially in relation to maximum streamflow, by means of a brief literature review. In short, it can be observed that different methods are applied and tested in order to obtain regionalization results associated with lower uncertainties, and there is no standardized method, once there are hydrological specificities of different locations.

Authors: Deimary Nima , Mohammadi Mohammad
Published: May 2020

Ancient sports, dating to the size of the history of Mithraism, have undergone many changes throughout history and have been mixed with Sufism and Shiism. As a result of these developments, Zurkhaneh's building also has a distinct root in the Islamic era by preserving patterns of the ancient world. The structure and its components are based on beliefs and sentiments that have been exhibited in different shapes in the architecture of Zurkhaneh building throughout history, holding symbolic concepts like sacred numbers. As in other examples of Iranian architecture, it has played a major role in the formation of architecture and sports of Zurkhaneh. Examples like the octagonal Field of Zurkhaneh, which is a symbol of the eight gates of Paradise and commemorating the eighth Shiite Imam, and the dome is a symbol of unity. This research tries to investigate the effect of sacred numbers on formation of archery sports and Zurkhaneh architecture by using a descriptive and analytic approach and using library documents and resources.

Authors: Sadeghi Navid , Araghi Maryam Khalili
Published: May 2020

The market value of the shareholders’ equity depends on the implementation of management policies in relation to long-term plans and it will be on the upside if executives focus on implementing these policies. If past events follow a constant process based on prior planning, performance prediction through past events will result.  In some cases, the performance of managers is based on increasing their own interests and based on their personal preferences, which causes misleading information about performance prediction to be shared with stakeholders and other beneficiaries. Managers try to predict unrealistic performance in order to increase their management fees by using intermediate and virtual variables which will reduce their professional validity and ultimately lead to a reduction in the market value of the equity. The market value of the shareholders’ equity is directly influenced by the conservative and courageous policies of managers. The purpose of this study is to investigate the effect of managers 'shift work and performance prediction on the market value of shareholders’ equity. This research is a library and analytical-causal study and is based on the analysis of panel data (data panel). In this research, the financial information of 102 companies listed in Tehran Stock Exchange during the period of 2008-2018 (612 companies - the year) has been investigated. The results of the research show that according to the analyzes carried out in relation to the confirmation of the first hypothesis of the research, the style of managers shift working has an adverse and inverse effect on the market value of the shareholders’ equity. Finally, with regard to the analysis made in relation to the confirmation of the second hypothesis of the research, we concluded that performance prediction has a positive and direct effect on the market value of the shareholders’ equity.

Wastewater from a cosmetics industry plant in the metropolitan area of Goiânia (Brazil) was the object of this research. It was analysed environmental parameters as absorbance, total iron, chemical oxygen demand, pH, total phenols, conductivity, H2O2, dissolved oxygen, turbidity, and total solids. They were analyzed in between processes at all stages.  The effects of Fe2+ (18.42-257.89 mg L-1) and H2O2 (500-2300 mg L-1) concentrations and pH values (3.00-5.50) were studied for the Fenton process treatment. In adsorption, the activated carbon was characterized by infrared spectroscopy, elemental analysis, adsorption and desorption of N2 and thermogravimetry (TG/DTA). The effect of the contact time (4min-24h) and of the temperature variation in the system 20-60 °C were studied. By integrating the two technologies, a satisfactory removal rate was achieved for the analyzed parameters in the total time of treatment of 82 minutes
Characterization and diagnosis of the process of reuse of electronic waste: case study in a specialized center in Recife, Pernambuco, Brazil
Authors: Ferraz Paulo Henrique Ribeiro
Published: May 2020

The expansion of the electro-electronic products market in Brazil, which occurred in the last decades, resulted in a higher volume of waste from electro electronic equipment (WEEE) generated due to the reduction of the useful life of the devices, having been the seventh largest generator of electronic waste in the country. in 2016. In Recife, an annual generation of 9,841 tons is estimated. Besides having materials of slow degradation, there are also heavy metals in the composition of electronic waste, harmful to the environment and living beings when in high concentration. Some studies have observed the insufficiency of actions by society regarding the correct disposal of WEEE. This research consists of a descriptive case study of the operation dynamics and reception rates of a specialized WEEE recycling center located in Recife, with collection points distributed throughout the city. Data from the first half of 2019 were analyzed. The study found the potential for reuse of donated equipment, as well as a greater contribution from the private sector, possibly reflecting the implementation of the National Solid Waste Policy.

Understanding the factors affecting stock return volatility, for analysts, investors and company executives, it is critical. In this study, using a traditional approach, we identify the factors influencing volatility and how price friction is formed on stock price stability, and in particular, examining the clustering test for price increases. This study was carried out by examining the price clusters and stock price stability in the stock market and the OTC market between 2009 -2010. Econometric software was used to investigate the research variables. In this study, we tried to study stock price volatility in proportion to stock price clusters. Research findings showed; there is no significant relationship between stock price volatility and price clusters in the OTC market and the stock market.
To the question of functionality of administrative compulsion
Authors: Kurakin Aleksei Valentinovich
Published: May 2020

This article explores the problems of application of measures of administrative compulsion, pays attention to functionality of measures of administrative compulsion, as well as state the thesis on the fact that despite vast attention to the issue of administrative compulsion, its functions lack scientific development. Considering the theoretical research, the author notices that functionality of administrative compulsion is predefined by the functionality of separate measures of administrative compulsion. Therefore, emphasis is made on the functions of some of the administrative compulsory measures. The theoretical framework of the study is comprised of the works of general theory of law and recent achievements in the science of administrative law. The conclusions of the research consist in a number of proposals on lowering the level of administrative compulsion in the law enforcement work, adjustment of the goals of some types of measures of administrative compulsion, as well as improvements to the positions of legislation determining functionality of certain measures of administrative compulsion. The article highlights the fact that the principal function of administrative compulsion consists in protection of rights and liberties of the citizens.

To assess the accuracy of different quantum mechanical methods for biochemical modeling, the reaction energies of 20 small model reactions (chosen to represent chemical steps catalyzed by commonly studied enzymes) were calculated. The methods tested included several popular Density Functional Theory (DFT) functionals, second-order Møller Plesset perturbation theory (MP2) and its spin-component scaled variant (SCS-MP2), and coupled cluster singles and doubles and perturbative triples (CCSD(T)). Different basis sets were tested. CCSD(T)/aug-cc-pVTZ results for all 20 reactions were used to benchmark the other methods. It was found that MP2 and SCS-MP2 reaction energy calculation results are similar in quality to CCSD(T) (mean absolute error (MAE) of 1.2 and 1.3 kcal mol−1, respectively). MP2 calculations gave a large error in one case, and are more subject to basis set effects, so in general SCS-MP2 calculations are a good choice when CCSD(T) calculations are not feasible. Results with different DFT functionals were of reasonably good quality (MAEs of 2.5–5.1 kcal mol−1), whereas popular semi-empirical methods (AM1, PM3, SCC-DFTB) gave much larger errors (MAEs of 11.6–14.6 kcal mol−1). These results should be useful in guiding methodological choices and assessing the accuracy of QM/MM calculations on enzyme-catalyzed reactions.

Aims: To analyze the importance and performance rate of various ecotourism component based on visitor perspectives in Helena sky bridge.

Study Design: Interview method.

Place and Duration of Study: October 2018 in Helena sky bridge, Bantimurung Bulusaraung National Park, Maros District, South Sulawesi Province, Indonesia.

Methodology: The interview method, by using prepared structured questionnaire with close ended questions, applied on 50 respondents selected through quoted accidental sampling technique. There were 33 ecotourism subcomponents assessed based on Likert scale. Obtained data processed by the Importance-Performance Analysis (IPA) and displayed in Cartesian diagram.

Results: There was variation of respondent characteristics in term of gender, age, number of visits, visiting purpose and domicile. However, most visitor was young people (18-28 years old) and come from Makassar. The highest performance rate was found on panorama, while the lowest performance rate was homestay. For the importance, the highest score was showed by 3 subcomponents, namely service, skill and garbage dump, while the lowest one was festival. In average, the performance rate of all subcomponents was 2.70 (moderate), while the importance was 3.93 (good). There was a gap between performance and importance that need proper management actions. Development effort should be concentrated in 7 subcomponents plotted in 1st quadrant, such as the easiness access to get transportation, guide and interpreter, public lavatory, garbage dump, health facility, shopping facility, and clean water availability. 13 subcomponents had already in a good performance, mostly from natural attraction. 10 subcomponents were classed into 3rd quadrant with low priority management strategy. Moreover, 3 subcomponents (cultural landscape, local peoples’ daily life and hospitality) were in 4th quadrant with possible overkill situation.

Conclusion: Ecotourism subcomponents such as the easiness access to get transportation, guide and interpreter, public lavatory, garbage dump, health facility, shopping facility, and clean water availability should be prioritized.
