Advancing an Ecosystem Approach in the Gulf of Maine
Authors: Taylor Peter
Published: December 2020

Abstract.—In this paper, we synthesize the current thinking of scientists involved in the 2009 Gulf of Maine Symposium about successes and challenges in communicating the science underlying ecosystem-based management (EBM) and summarize the evolution of this issue as reflected in past Gulf of Maine symposia. We present survey results from scientists, representing a range of disciplines, that indicate a critical need for strategic communication as part of EBM. We focus primarily on the transfer of science to policy makers and managers, both of whom play an influential role in shaping current and future public opinion and practice. We illustrate best practices to enhance communications about EBM and offer recommendations for using communication techniques to speak to people from their cultural lens and knowledge base. We assert that “strategic communication” is necessary to enable EBM, and scientists, managers, and communication professionals must work together to employ its principles within a coherent framework.

Toplumların hızlı değişimleri, sanayi ve teknolojideki hızlı ilerlemeler, köyden kente göç, suç olgusunun daha görünür olması toplumun hemen her kurumda olumlu ve olumsuz etkilenmelerini de beraberinde getirmiştir. Yapılan araştırmalar toplumda yaşanan hızlı değişikliklerin toplumsal ilişkilerde ve aile ilişkilerinde çözülmeyi de beraberinde getirdiğini ortaya koymaktadır. Aile kurumunda meydana gelen çözülmeler; çocukların sevgi, özgüven, saygı ve bağlanma gibi duygularından yoksun yetişmelerine, psiko-sosyal açıdan gelişim dönemlerini sağlıklı tamamlayamadan büyümelerine ve benlikleri örselenmiş bireyler olarak topluma katılmalarına neden olmaktadır. Bunun yanı sıra azımsanmayacak sayıda çocuk, dünyaya geldikleri aile ortamında biyolojik, sosyolojik ve psikolojik gelişimlerini sağlıklı sürdürmeleri mümkün olmadığından, yetkili organlar tarafından gelişimlerini daha sağlıklı tamamlayabilecekleri kurumlarda korunma ve bakım altına alınmaktadırlar. Çocuk koruma alanında ülkelerin modern anlamda tercih ettikleri hizmet modeli ise günümüzde koruyucu aile yanında çocuklara sağlanan bakımdır. Dünyada koruyucu aile uygulamasını modern anlamda uygulayan ülkelerden biri İngiltere’dir. Türkiye’de ise çocuk koruma sistemi içerisinde, koruyucu aile uygulaması oldukça köklü bir geçmişe sahiptir. Bu makalenin amacı Türkiye’de koruyucu aile yanına yerleştirilecek çocukların tespit edilmesi, koruyucu ailelerin belirlenmesi veya koruyucu ailelerin yanına yerleştirilen çocukların takip edilmesi gibi daha pek çok konuda iyileştirilmesi gereken sorunları tespit etmek ayrıca İngiltere’nin koruyucu aile uygulamalarının Türkiye’den farklılıklarını ortaya koymaktır.

Authors: MANNASOĞLU Huriye , BAYKAL Nazlı
Published: December 2020

Reflection has a crucial role in learning to teach as a long developmental process. This case study focuses on the engagement of a teacher of English as a foreign language (EFL) in reflection. The teacher was engaged in a 12-week reflection process which included two-phase procedures repeated five times. The first phase of each procedure involved reflection on lexical problems through journals and peer discussions. The second was for reflection on classroom practice through journals and interviews. With a sequential exploratory mixed methods design, the study involved analysis of the teacher’s reflections first qualitatively and then quantitatively. The qualitative analysis was based on the taxonomies for descriptive and critical reflection presented in Ho and Richards (1993) and Farrell (1999). The quantitative side involved one-way goodness-of-fit chi-square test results. The results revealed that she referred to most of the topics in the taxonomy, and the top three were students’ problems, an approach/procedure, and positive evaluations of lessons. Overall, her critical reflection outnumbered her descriptive reflection, and was mostly related to evaluating teaching. The teacher also displayed development in the sense of critical reflectivity. All the quantitative analyses had statistically significant results. Globally, her reflection in journals, discussions, and interviews enabled her to respond to the context, engage in conscious deliberation, and integrate knowledge into the teaching act. In this way, the study is expected to contribute to the participant’s professional development.

Authors: Sutawidjaya Ahmad Hidayat , Nawangsari Lenny Christina , Nor Norashidah Mohamed
Published: December 2020

The most significant impacts on the environment and society of corporate operations occur in the supply chain. Environmental impacts occur at different stages of the environmental life cycle and relate to the extraction of raw materials from the earth, the processing and manufacturing of building materials, the construction process, operation or use, maintenance and repair, repair and eventual disposal or reuse of materials. Environmental phenomena of climate change or global warming are the result of human practice. Global warming causes an increase in ocean temperatures and surface of the book, causing melting of polar ice caps and rising sea levels. Another phenomenon of waste and sewage problems has become a national and international problem. Every supply chain activity in a series of production activities has an impact on the environment. Supply chains can have different organizational structures that reflect business relationships or the level of collaboration between chain companies. This study examines the relationship of Life Cycle Assessment (LCA) with Environment Supply Chain Management (ESCM) and Sustainability Supply Chain in Manufacture in Indonesia.

Authors: Khaleeli Majdi , Faisal Rouhi , Anwar Shaista
Published: December 2020

Green management and its implementation and practices attracted the attention of both practitioners and academicians alike, which in part is due to its positive impact on the environment and sustainability, however, little is known about what really measures the effect of green management practices on business performance. Conventional measures of financial performance cannot reflect the proposed effect since green management is long-term oriented and not limited to financial performance only. This research explores the potentials of using balanced scorecard to measure the effect of green marketing, green supply chain and green human resources on the performance of the firms. Simple random sampling technique was followed in this research, and data were collected from 113 managers from different companies in service and manufacturing sectors in UAE. The findings indicate that green marketing was the major determinant of customers’ performance, green human resources was the major factor affecting learning and growth, and that green supply chain was the main influencer on financial performance and internal processes.

Analysis of Zakat Accounting and the Role of the Internal Control System based on Financial Accounting Standards Guidelines (PSAK 109) Zakat Agency in Indonesia
Authors: Setiyawati Hari
Published: December 2020

This research was carried out because of the phenomenon of the large potential of zakat in Indonesia and the large number of zakat funds that were corrupted due to unaccountable financial reporting. Many payers of zakat (muzakki) still do not believe in National Zakat Agency (BAZNAS), so zakat payments are often not made through the official of BAZNAS. This research was carried out through a survey which was designed to examine the accountability of financial reporting at the amil zakat and amil zakat institutions in Jakarta and Banten, related to internal control competencies and financial reporting accountability. The expected results of this study are an increase in the accountability of financial reporting by conducting sharia accounting training for staff in amil zakat and amil zakat institutions in Jakarta and Banten. The goal of this study is to contribute scientifically to the science of sharia accounting, specifically accounting for zakat, and to assist accounting departments in preparing financial statements. The results of this study state that compliance with the application of zakat accounting with Financial Accounting Standards Guidelines (PSAK 109) had no significant effect on financial reporting accountability, while the role of the internal control system had a significant positive effect on financial reporting accountability.

Authors: Alawaqleh Qasim Ahmad
Published: December 2020

This study advances the Accounting Information System (AIS) study by exploring the relationship between the AIS internal audit quality. It develops a model based on literature and considers one significant variable of mediation that is organizational culture. The AIS is expected to influence internal audit quality in different contexts, particularly in developing countries. The research model validated using AMOS and SPSS version 25. Based on a sample of 183 internal auditors in Jordanian industrial SMEs, empirical findings support the relationship between AIS and internal audit quality; however, the impact is direct while the organizational culture partially mediates this relationship. The results indicate that the AIS help enhance internal auditors' quality and the organizational culture, ultimately improving internal audit quality. The implications are useful for academics, administrators, and policymakers interested in evaluating the impact of intervening variables on the AIS and the internal audit quality relationship.

Spin-1/2 XXZ Heisenberg cupolae: magnetization process and related enhanced magnetocaloric effect
Authors: Karl'ová K.
Published: December 2020

The magnetization curves and magnetocaloric effect during the adiabatic demagnetization of antiferromagnetic spin-1/2 XXZ Heisenberg clusters with the shape of Johnson's solids (triangular cupola, square cupola and pentagonal cupola) are investigated using the exact numerical diagonalization for different values of the exchange anisotropy ranging in between the Ising and fully isotropic limit. It is demonstrated that spin-1/2 XXZ Heisenberg cupolae display, in comparison with their Ising counterparts, at least one more magnetization plateau. The novel magnetization plateaux extends over a wider range of the magnetic fields with increasing of a quantum part of the XXZ exchange coupling at the expense of the original plateaux present in the limiting Ising case. It is shown that the spin-1/2 XXZ Heisenberg triangular and pentagonal cupolae exhibit an enhanced magnetocaloric effect in the vicinity of zero magnetic field, which makes these magnetic systems promising refrigerants for cooling down to ultra-low zero temperatures.

The article offers a methodic approach to the solution of the issue of main stock usage effectiveness index definition. Traditionally the main stock usage effectiveness calculation is carried out by balance and residual values. This approach in whole ignores (except for two coefficients) the wearing-out of main stocks and tortures the real view of their actual condition. In connection with this, in some oil-gas production boards (OGPB) of «Azneft» PU was conducted a comparative analysis of index system of usage effectiveness of main stocks that have been calculated by balance and residue values. The investigations have a great theoretical significance and in practice may be applied by OGPB in the analysis of enterprise industry activity.

The article deals with the issues connected with rationing of gas production losses at oil-and-gas production enterprises. The evaluation of process losses is presented; the structure and system of their accounting are considered. Associated and natural gas losses breakdown is given by sources of their origin and trends of required gas for own consumption of oil and gas producing enterprises are classified. Based on generalized theoretical and practical material on the setting of norms for losses, a standard technique for process losses of gas and its own consumption has been developed. Norms of process losses and gas for own consumption were calculated based on the technique for nine OGPDs, two underground gas storages of the Azneft PU and eleven oil and gas operating companies. Structural constitution of process losses was analyzed at all these enterprises, a comprehensive benchmarking of loss rate was carried out, a flow diagram of standard own consumption of gas was constructed, and conclusions were drawn.
Self-efficacy and job satisfaction of teachers in schools for students with disabilities
Authors: Žunić-Pavlović Vesna , Pavlović Miroslav
Published: December 2020

Introduction. Self-efficacy significantly affects teaching outcomes and professional life of teachers. Although there are numerous research studies on self-efficacy and job satisfaction of teachers, studies that deal with teachers in special education are scarce. Objectives. The research had the following two goals: first, to determine the differences in self-efficacy and job satisfaction between teachers in secondary schools for students with disabilities and teachers in secondary vocational schools, and second, to examine the relationship between self-efficacy and job satisfaction in these two groups of teachers. Methods. The sample consisted of 96 teachers in schools for students with disabilities and 372 teachers in vocational schools. Ohio State Teacher Efficacy Scale, Short form (OSTES) and Teaching Satisfaction Scale (TSS) were used. Results. Teachers in schools for students with disabilities differed significantly in the level of self-efficacy and job satisfaction compared to teachers in vocational schools. In both groups of teachers, there was a significant positive relation between self-efficacy and job satisfaction. Conclusion. The results of this research suggest that teachers with a higher level of self-efficiency are generally more satisfied with their job. This finding may have significant implications for teacher professional development. The determined differences between the two groups of teachers justify the need for an in-depth study of the relation between self-efficiacy and job satisfaction.
Empathy and systemizing in preschool children
Authors: Janković-Nikolić Marina
Published: December 2020

Introduction. The Empathizing-Systemizing theory sees empathy and systemizing as two independent dimensions, which can be used for classification into five cognitive profiles or "brain types". Objective. The aim of this research was to determine the relationship between empathy and systemizing in preschool children, and to determine gender differences in these abilities and brain types. Method. The sample consisted of 71 children from 5/6 to 7 years of age. Children's versions of the Empathy Quotient - EQ-C and Systemizing Quotient SQ-C (Auyeung et al., 2009) were used to assess empathy and systemizing. Results. According to our results, empathy and systemizing were moderately correlated: participants with higher empathy quotient also had a higher systemizing quotient. There were no gender differences in the assessed abilities. The only exception is the difference in the score calculated by subtracting systemizing and empathy quotient. On average, girls had the empathy quotient higher than the systemizing quotient, while boys showed the opposite pattern. There were no gender differences in the distribution of cognitive profiles ("brain types") based on the aforementioned difference between systemizing and empathy. Conclusion. The results of this study may be used as baseline for comparison in future studies that would examine typically and atypically developing children.

The subject of this research is the soils and soil-geochemical catenae in the area of Yeletsky settlement, located in the northeast of the Komi Republic. Catena were deposited on the mound covered with moss-shrub tundra transect from the interfluve of Usa and Yelets Rivers to a lacustrine depression, complicated by arching permafrost mounds. Within the district of research, the authors laid five soil incisions (EL20-P1, EL20-P2, EL20-P3, EL20-P4 and EL20-P5) that formed a soil-geochemical catena along the slope. Complex land cover found at the periphery. The explored soils were formed on silty loams with permafrost horizon at a depth of 0.5-0.7 m and belong to Cryosols, Turbic Cryosols and Histic Gleysols. Cryosols in the upper part of catena show specific cryogenic granular structure due to lack of soil moisture content. The soils on the slope and in the depression are more saturated with water; therefore, structureless Turbic Cryosols and Histic Gleysols are formed. In the soil horizons, the values of pH and electrical conductivity were measured, the content of organic carbon and soil texture were studied. An increase in soil acidity on organogenic zones by 4.3 - 5.7 was noticed; in underlying horizons the pH values reach 6.9.

Published: December 2020

The subject of this article is the pollen spectra of the samples from the surface of Romantic's Glacier, located in the Polar Urals in the Rai-Iz mountain range, as well as generalization of the results of published studies dedicated to glaciers of the Urals. The author also examines the pollen spectra of massive ice, which can be attributed to ice of atmospheric origin on the basis of similarity with the pollen spectra obtained from the surface of the glacier. The article reviews climatic peculiarities of the Polar Urals due to the existence of glaciers below the snow line, namely the landscapes of the Polar Urals, including vegetation as a source of pollen and spores falling onto the surface of glaciers of the Polar Urals, as well as possibility of distant pollen drift to the surface of Romantic’s Glacier. The main result consists in the conclusion that the composition pollen spectra of the Romantic’s Glacier in the Rai-Iz mountainous area is mainly determined by the long-range transport of pollen and spores from the western and south-western regions in a latitude direction. The pollen spectra obtained from the surface of the Romantic’s Glacier are characterized by significant presence of various pollen from broad-leaved rocks of lip, maple, oak, and hazel. Pine pollen and high forest birch are prevalent. Local vegetation is very poor. However, the pollen spectra indicates pollen of heath and crowfoot family, and grasses.

Due to the outstanding mechanical and electronic properties, graphene has been widely investigated as the nano-filler for fabricating metallic matrix composites. The key point in these studies is how to realize a uniform distribution of graphene in the metallic powders. The traditional methods mainly include ball-milling and colloidal processing. However, both of them result in massive structural defects on graphene flakes and further degrade its strengthening effects. Therefore, it is meaningful to explore a new method. In this study, we present a new way, i.e. in-situ growth of graphene on copper powders in the plasma enhanced chemical vapor deposition system (PECVD). The scanning electron microscope(SEM) images indicate that the powder is fully covered by graphene nanoflakes, realizing uniform mixing on a micro-scale. Further research finds that there exists a competition between growth and etching at the initial stage of the graphene growth. Methane is dissociated into various active species (CHx, atomic H and C) by the radio frequency. The C atoms self-assemble into graphene islands, yet the H atoms tend to etch these islands away. At a lower temperature, the etching effect takes a dominant position and then only the bigger islands are able to survive in this process, resulting in bigger graphene nanoflakes. As a contrast, it is a growth-dominant process at higher temperature, resulting in a much higher nucleation density and smaller graphene sheets. Therefore, the size of graphene sheets can be well controlled by tuning the growth temperature, for example, the sizes are 300 and 100 nm at 500 ℃ and 600 ℃ respectively. Moreover, the X-ray photoelectron spectroscopy(XPS) spectra show that the oxide layer at the surface of copper powder can be removed as the graphene flakes grow, which contributes to a fine interface between the two parts and further leads to outstanding performance of the final composite. The powder is consolidated by spark plasma sintering(SPS) technique, and several properties of this composite are tested. The results indicate that compared with the pure copper, the copper with the addition of graphene can reduce the resistivity by one order of magnitude and increase the hardness and yield strength by 15.6% and 28.8%, respectively. This work provides an alternative way to fabricate graphene-enforced composite and shows promising application prospects.
La prensa anarcofeminista: una “incisiva” plataforma escritural en el periódico La Voz de la Mujer
Authors: Contreras Candia Leticia
Published: December 2020

Este artículo analiza los espacios de (auto)representación disidentes a los imaginarios hegemónicos de modernización nacional configurados en el periódico comunista-anárquico argentino La Voz de la Mujer (1896), en concreto analizaremos una columna, sin título, firmada por Pepita Guerra. Con este propósito, adoptaremos un enfoque crítico desde los estudios de género que permita explorar las luchas ideológicas del sistema sexo-género en la Argentina decimonónica. Encontramos en el ejercicio escritural de Pepita Guerra la articulación de subjetividades alternativas, en clave feminista, que fisuran los ordenamientos corporales y los imperativos de género femenino elaborados por el discurso estatal del siglo XIX.

Pain has always been a cause of concern to humans. People often searched for remedy from plants because of the many documented side effects of commercial medicines. This study was conducted to determine the analgesic efficacy of the root decoction of Salacia korthalsiana Miq (Polipog) found in Mondragon Northern Samar. Acetic acid-induced writhing method was used to test the analgesic activity of polipog. Writhing test is a chemical method used to induce pain of peripheral origin by injection of irritant (ex. acetic acid). The manifestations of abdominal writhing in mice were described as an arching of back, extension of hind limbs and contraction of abdominal musculature. Analgesic activity of the test compound is inferred from decrease in the frequency of writhing.  From the results obtained, polipog is comparable to the commercially available drugs in terms of analgesic efficacy.

Published: December 2020

Nitrogen‐containing heterocycles have attracted considerable attention due to their extensive applications in the fields of organic synthesis, pharmaceuticals, agrochemicals, and materials science. This review focuses on the recent advances in the synthesis of nitrogen‐containing heterocycles via the cyclization of alkynyl imines. By using this protocol, a variety of nitrogen‐containing heterocycles, mainly including four‐, five‐, six‐, and seven‐membered nitrogen‐containing heterocycles, aza‐spirocycles, and fused aza‐heterocycles, could be obtained efficiently under mild conditions. Additionally, mechanistic features of these transformations are also discussed.

Characterization of glutathione S‐transferase enzyme from brown meagre (Sciaena umbra) and inhibitory effects of heavy metals
Authors: Guven Neslihan , Soydan Ercan
Published: December 2020

Glutathione S‐transferase (GST) detoxifies a broad spectrum of xenobiotics, especially in chemotherapeutic drugs, endogenous molecules, and environmental pollutants. Since the enzyme metabolizes toxic compounds, it has been extensively studied in many living things including aquatic organisms. In the current study, the GST enzyme was purified from brown meagre (Sciaena umbra) muscle tissue for the first time. Then, kinetic parameters of the enzyme were determined as optimum ionic strength: 20 mM Tris/HCl, optimum pH: 7.0 (Tris/HCl), and optimum substrate concentration: 3.125 mM. Eventually, inhibitory effects of the heavy metals were evaluated. IC50 values of the tested metal ions were calculated to be 0.1112, 0.6113, 0.727, and 0.7774 mM for Cd2+, Fe3+, Ag+, and Cu2+, respectively. Our results show that these heavy metals inhibit GST at very low concentrations which could cause dangerous results for aquatic systems.
An Attempt to Formulate Non‐Carbonate Electrolytes for Sodium‐Ion Batteries

Published: December 2020

Non‐aqueous carbonate solvents have been the main choice for the development of lithium‐ion batteries, and similarly most research on sodium‐ion batteries have been performed using carbonate‐based solvents. However, the differences between sodium and lithium batteries – in term chemistry/electrochemistry properties as well as electrode materials used – open up opportunities to have a new look at solvents that have attracted little attention as electrolyte solvent. This work investigates properties of a wide range of different solvent classes in the context of sodium‐ion battery electrolytes and compares them to the performance of propylene carbonate. The thirteen solvents studied here include one or several members of glymes, carbonates, lactones, esters, pyrrolidones, sulfones, and alkyl phosphates. Out of those, five outperforming solvents of γ‐butyrolactone (GBL), γ‐valerolactone (GVL), N‐methyl‐2‐pyrrolidone (NMP), propylene carbonate (PC), and trimethyl phosphate (TMP) were further investigated using additives of ethylene sulfite (ES), vinylene carbonate (VC), fluoroethylene carbonate (FEC), prop‐1‐ene‐1,3‐sultone (PES), sulfolane (TMS), tris(trimethylsilyl) phosphite (TTSPI), and sodium bis(oxalato)borate (NaBOB). The solvents TMS and tetraethylene glycol dimethyl ether (TEGDME) were tested in 1 : 1 mixtures by volume with the co‐solvents; NMP, dimethoxyethane (DME), and TMP. All electrolytes used NaPF6 as the salt. Primary evaluation relied on electrochemical cycling of full‐cell sodium‐ion batteries consisting of Prussian white cathodes and hard‐carbon anodes. Galvanostatic cycling was performed using both two‐ and three‐electrode cells, in addition, cyclic and linear sweep voltammetry was used to further evaluate the electrolyte formulations. Moreover, the resistance was measured on the anode and cathode, using Intermittent current interruption (ICI) technique.
Moving from residual lignocellulosic biomass into high‐value products: Outcomes from a long‐term international cooperation

Published: December 2020

Major progress in the bioprocessing of lignocellulose to fuels and value‐added chemicals has created the possibility of a low carbon‐footprint economy. However, the current complexity and associated costs of lignocellulose conversion result in a higher price for ethanol than for fossil fuels. The cost of cellulosic ethanol production will be lowered by further progress in development of biorefinery technology that produces both ethanol and high‐value chemicals with bio‐based products that are beginning to penetrate consumer markets in the USA, Brazil, and worldwide. The cost‐effectiveness of low carbon‐footprint bioproducts will benefit from advances in supplying large amounts of biomass solids to the biorefinery. We describe here outcomes from a successful long‐term international cooperation between the Laboratory of Renewable Resources Engineering (LORRE) at Purdue University in the United States and Brazil's Agricultural Research Corporation (EMBRAPA) and Federal University of São Carlos (UFSCar), which has contributed practical pathways to enhance the biorefinery concept. This paper gives an overview of developments that address fundamental knowledge of lignocellulosic biomass pretreatment hydrolysis under optimized operational conditions and bioreactor configurations, and the science and engineering that contributes to the effective production of fuel and ethanol and value‐added products from biomass. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd
