Analysis of a Productive Topological Index Correlated to Fullerenes’ Physical Properties

Fullerene is a cage-like carbon allotrope admitting a vast range of applications. Some of the important fullerenes are C54,C58,C60,C70,C74,C76,C78,C80C82,C84,C86,C90. The physical properties of fullerenes can be exhibited using the degree-based topological indices. The sum based geometric arithmetic index is significant in this manner. The sum based atomic bond connectivity, Randic, first and second Zagreb indices are well known topological indices. We have determined the regression relation between each of these indices and the sum based geometric arithmetic index. Moreover, the correlation coefficient is also calculated. Correlation is a symmetric relation, as it provides association between two variables. On the basis of regression analysis and correlation coefficient, it was found that each of this index is strongly related to the sum based geometric arithmetic index. Moreover, we have computed the regression relations concerning the physical properties depending on the sum based geometric arithmetic index. The physical properties include binding energies, Ramsauer-Townsend minima, shape resonances and heat of formation of fullerene molecules. It was concluded that the sum based GA index is the best in presenting the heat of the formation of molecules.

Certain Solutions of Abel’s Integral Equations on Distribution Spaces via Distributional Gα-Transform

Abel’s integral equation is an efficient singular integral equation that plays an important role in diverse fields of science. This paper aims to investigate Abel’s integral equation and its solution using Gα-transform, which is a symmetric relation between Laplace and Sumudu transforms. Gα-transform, as defined via distribution space, is employed to establish a solution to Abel’s integral equation, interpreted in the sense of distributions. As an application to the given theory, certain examples are given to demonstrate the efficiency and suitability of using the Gα-transform method in solving integral equations.

Dispersion relations, knots polynomials, and the q -deformed harmonic oscillator

We show that the crossing symmetric dispersion relation (CSDR) for 2-2 scattering leads to a fascinating connection with knot polynomials and q-deformed algebras. In particular, the dispersive kernel can be identified naturally in terms of the generating function for the Alexander polynomials corresponding to the torus knot $(2,2n+1)$ arising in knot theory. Certain linear combinations of the low energy expansion coefficients of the amplitude can be bounded in terms of knot invariants. Pion S-matrix bootstrap data respects the analytic bounds so obtained. We correlate the $q$-deformed harmonic oscillator with the CSDR-knot picture. In particular, the scattering amplitude can be thought of as a $q$-averaged thermal two point function involving the $q$-deformed harmonic oscillator. The low temperature expansion coefficients are precisely the $q$-averaged Alexander knot polynomials.

A multimodal analysis of the picturebook Daddy, Papa, and Me (2009). Deconstructing representational, interpersonal and compositional meanings

This article offers a multimodal discourse analysis of the picturebook Daddy, Papa, and Me (2009), in which there is a two-father family with a child. The aim of this article is to analyse how the written text and the visual create meaning and to observe if the child has a symmetrical relationship with both fathers. We will follow the method of Visual Social Semiotics developed by Kress and van Leeuwen (2006) based on Halliday’s Systemic Functional Linguistics, in order to explore the representational, interpersonal and compositional meanings. The analysis will show that the child and his fathers are dynamic, as the actions represented in the visuals and the use of materials makes clear. However, the multimodal analysis does not encourage interaction with the readers, because most of the visuals are offers and the predominance of oblique angles. Images and written text are intergrated in the layout, but visuals are salient so that children can understand the meaning of the picturebook just looking at the images. The writer and the illustrator collaborate to tell the story in a simple way, with the aim of making the plot accessible to children and to invite them to identify with the actions being narrated.

Symmetric relations, symmetric theories, and Pythagrapheanism

AbstractIt is a metaphysical orthodoxy that interesting non‐symmetric relations cannot be reduced to symmetric ones. This orthodoxy is wrong. I show this by exploring the expressive power of symmetric theories, i.e. theories which use only symmetric predicates. Such theories are powerful enough to raise the possibility of Pythagrapheanism, i.e. the possibility that the world is just a vast, unlabelled, undirected graph.

Evaluating the symmetric and asymmetric effects of fossil fuel energy consumption and international capital flows on environmental sustainability: a case of South Asia.

South Asia is primarily affected by environmental degradation. As a result, it is worthwhile to explore the impact of international capital flows on the ecological sustainability of the South Asian region. There are many studies in the literature on the CO2-remittances nexus, CO2-FDI nexus, and CO2-economic growth; however, no study has yet taken remittances and FDI into account in the symmetric and asymmetric model for the South Asian region. To address the research gap, this study investigates the effect of international capital flows, fossil fuel energy consumption, and economic growth on South Asian carbon emissions. This study examines the effect of fossil fuel energy consumption, remittances, foreign direct investment, and economic growth on the environmental sustainability of the South Asian region from 1975 to 2020. Autoregressive distributive lag (ARDL) and non-linear ARDL (NARDL) models are used to estimate the symmetrical and asymmetrical relationships among the variables. The findings of the ARDL models reveal that fossil fuel energy consumption and economic growth increase while remittances and FDI decrease carbon dioxide (CO2) in the long run. According to the NARDL empirical findings, positive remittances and negative FDI shock reduce CO2. Besides, the positive and negative fossil fuel energy consumption shock increases CO2. Moreover, the positive (negative) economic growth shock increases (decreases) CO2. The cumulative dynamic multipliers revealed the adjustment pattern to new long-run equilibria. The study recommends that policymakers regard remittances and FDI as policy instruments, particularly when developing long-term strategies and policies connected to environmental quality.

Mangrove Forest Management Stakeholder Social Network in Langkat Regency

This study examines the social network of stakeholders managing mangrove forests sustainably in Langkat Regency. The existing conditions that have occurred so far show that the government has yet to be able to synergize with stakeholders through a mangrove forest management program that involves local community participation in a sustainable, synergistic, and systemic manner. Identifying stakeholder networks is very important to become a reference in designing a systemic and sustainable mangrove forest management program. Stakeholders who manage mangrove forests in Lubuk Kertang Village and Pasar Rawa Village form a symmetrical relationship through participatory group partnerships. The existing network forms, including tenure aspects (forest land tenure rights), and social and economic constructions, provide a significant background and influence on efforts to rehabilitate degraded mangrove forests. Within this scope, social networks can be understood to determine access rights, management rights, and governance of mangrove forests. The purpose of this research is to find out the shape of the network and the role of stakeholders (actors and institutions) as managers of mangrove forests. The method used is qualitative, with descriptive analysis techniques to analyze the shape of the network and the role of stakeholders (actors and institutions) as managers of mangrove forests. Keywords: [Social Networks, Stakeholders, Social Mapping, Mangrove Forest Management]

Mothers of deaf children undergoing early development support in terms of parenting competences

The paradigm of family-centered early childhood intervention indicates that the family and professionals are in a symmetrical relationship and share responsibility for taking appropriate measures to provide the child and his/her family with adequate support based on the family's needs and resources. The aim of the study was to identify the level of parental competences (translated as parents' dispositions conditioning their use of such ways of dealing with the child that fosters its development - shaping the child's autonomy and self-regulation skills and sense of efficacy) of parents of children undergoing early intervention, in this case, children with hearing impairment. The study covered 52 randomly chosen mothers. Parental Competence Test by Anna Matczak and Aleksandra Jaworowska was used to measure outcome results.

On a system of ( p , q ) -analogues of the natural transform for solving ( p , q ) -differential equations

In this work, we apply the concept of \((p,q)\)-calculus or post quantum calculus to establish the definitions of \((p,q)\)-analogues of the natural transform of the first and second kind, which is a symmetric relation between \((p,q)\)-analogues of the natural, Laplace, and Sumudu transforms. Moreover, as a result of the convolution theorem, some properties and some functions present in the table of \((p,q)\)-analogues of the natural transform are discussed. Also, we apply them to solve higher order \((p,q)\)-IVP with constants and coefficients, and to show the performance and effectiveness of the proposed transform.

Approximation operators and accuracy measures of rough sets from an infra-topology view.

In this work, our target point is to focus on rough approximation operators generated from infra-topology spaces and examine their features. First, we show how infra-topology spaces are constructed from -neighborhood systems under an arbitrary relation. Then, we exploit these infra-topology spaces to form new rough set models and scrutinize their master characterizations. The main advantages of these models are to preserve all properties of Pawlak approximation operators and produce accuracy values higher than those given in several methods published in the literature. One of the unique characterizations of the current approach is that all the approximation operators and accuracy measures produced by the current approach are identical under a symmetric relation. Finally, we present two medical applications of the current methods regarding Dengue fever and COVID-19 pandemic. Some debates regarding the pros and cons of the followed technique are given as well as some upcoming work are proposed.

The significance of mixed states in mania and depression: From the psychopathological viewpoint of Tadao Miyamoto.

This article introduces the concept proposed by the eminent second-generation Japanese psychopathologist Tadao Miyamoto in 1992 that the manic-depressive mixed state is the basic psychopathology of manic-depressive illness. When Kraepelin first established the dichotomy between schizophrenia and manic-depressive illness, mania and depression were placed in a symmetrical relationship. Now, in Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5), manic-depressive illness is divided into two distinct categories: bipolar and related disorders, and depressive disorders. Miyamoto pointed out that even in the average depressed state there is a manic-depressive mixed state and listed the following findings. The depressed mood of depression is itself a major fluctuation, but is constantly subject to more or less subtle fluctuations or swaying. What occurs in association with the incessant fluctuations of mood dysphoria are restlessness, agitation, irritability, and excitement, which manifest in a unique way in combination with a depressive mood. In depressive delusions, ideations of belittlement are developed in an exaggerated manner. Miyamoto concluded that mixed states are not incidental or accessory to manic-depressive illness; on the contrary, they may form a core component of manic-depressive illness.

A Method Converting Multi-Properties Objective Reachability Problems to Multi-Objective Sets Reachability Problems over FKS

In this paper, we focus on the symmetrical relationship between multi-properties objective reachability problems and multi-objective sets reachability problems over FKS based on Zadeh logic. First, we give the formal definitions of those two problems. Then, we study their relationships and find that a multi-properties objective reachability problem and a special case of multi-objective sets reachability problems have symmetry. Finally, we give a polynomial time algorithm based on this symmetry to convert a multi-properties objective reachability problem to a multi-objective sets reachability problem. In addition, an illustrative example is listed to express some possible application methods based on our work.

Locality and analyticity of the crossing symmetric dispersion relation

This paper discusses the locality and analyticity of the crossing symmetric dispersion relation (CSDR). Imposing locality constraints on the CSDR gives rise to a local and fully crossing symmetric expansion of scattering amplitudes, dubbed as Feynman block expansion. A general formula is provided for the contact terms that emerge from the expansion. The analyticity domain of the expansion is also derived analogously to the Lehmann-Martin ellipse. Our observation of type-II super-string tree amplitude suggests that the Feynman block expansion has a bigger analyticity domain and better convergence.

Tahvil ve Hisse Senedi Piyasaları Arasında Zamanla Değişen Nedensellik İlişkileri: Hatemi-J Dinamik Nedensellik Testi Bulguları

İktisadi gelişmeler ve risk faktörlerindeki belirsizlik durumu varlık sınıfları arasındaki ilişkileri zamana bağlı olarak değiştirebilmektedir. Finans teorisinde merkezi bir konumda olan tahvil ve hisse senedi piyasaları arasındaki nedensellik ilişkilerine odaklanan bu çalışma, tahvil piyasasından hisse senedi piyasasına doğru simetrik ve asimetrik nedensellik ilişkisinin olup olmadığını ve eğer varsa bu ilişkinin zamana bağlı olarak değişip değişmediğini ortaya koymayı amaçlamaktadır. Analiz yöntemi olarak Hatemi-J (2021) tarafından geliştirilen dinamik simetrik ve asimetrik nedensellik testleri benimsenmiştir. Analiz Ocak 1980 ile Nisan 2022 tarihleri arasında gerçekleştirilmiş ve ABD (Amerika Birleşik Devletleri) tahvil ve hisse senedi piyasası incelenmiştir. Dinamik simetrik ve asimetrik nedensellik testi bulguları tahvil piyasasından hisse senedi piyasasına doğru olan nedensellik ilişkisinin zamana bağlı olarak değiştiğini göstermektedir. Yani tahvil piyasası ile hisse senedi piyasası arasındaki nedensellik ilişkilerinde yapısal değişimler ve zaman bağımlılığı mevcuttur. Bu durumda statik modellerin riskten korunma, çeşitlendirme ve varlık dağılımı gibi kararlarda taraflı yönlendirme yapabileceği ortaya konulmuş olmaktadır.

EFL TEACHING AND THE ISTE DESIGNER AND FACILITATOR STANDARDS: AN EXPLORATORY OUTLOOK

Nowadays, scholars and researchers adhere to the prominent role information and communication technologies (ICT) play in education, particularly in language teaching. The International Society for Technology in Education (ISTE) has developed a set of standards that provide a framework for developing digital competencies among educators, students, administrators, coaches, and computer science teachers. In light of ISTE standards for educators, the present paper probes the roles teachers play with special reference to the designer and facilitator standards. The target population are EFL Moroccan high school teachers who work in the private sector in the Directorate of Marrakesh, Morocco. Through a quantitative analysis, findings indicate that the teachers in question generally fulfill their roles as ICT designers and facilitators. They adopt technology as a buttressing tool to install a learning-favorite environment. Plainly enough, they use technology-enhanced activities that promote student-centered learning. To a lesser degree, they facilitate collaborative learning and encourage the students to act globally by getting them engaged with the real world through technology. Likewise, this study discloses the existence of a symmetrical relationship between the mastery of internet/computer skills and the use-effectiveness of ICT tools, such as the interactive board and the data shown. In this respect, this study accentuates how adequate training and professional development-bound upskilling can truly promote the target EFL teachers’ digital competencies and help them live up to their roles as ICT designers and facilitators.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0967/a.php" alt="Hit counter" /></p>

Optimizing older adult co-researchers’ involvement in PAR: proposed evaluation tool

PurposeThis paper aims to share a practical evaluation tool intended to guide and support the participation of older people in PAR projects. Participatory action research (PAR) studies with older adults have been increasing over the past ten years. Scientific evidence provides key principles for PAR projects to achieve meaningful participation by older people; however, respecting the ideals of PAR is not always straightforward.Design/methodology/approachThis paper presents a case study that evaluated the involvement of nonacademic researchers in a PAR project using an evaluation tool derived from a literature review of PAR undertaken with this population (Corrado et al., 2020). The study goals were first to assess the assets and limits of the older co-researchers’ participation within the PAR project, and second to provide a revised version of the evaluation tool to support future PAR with older people. First, the authors designed an evaluation tool for nonacademic participation in PAR studies by older people that covers three main themes: older people positioned as prominent research partners; symmetrical power relations between academic and nonacademic researchers; and commitment regarding inclusiveness and long-term collaboration. Second, the authors performed an evaluation using this tool within the Active Aging with Dignity PAR Project.FindingsThird, the authors used the results of this experiment to suggest improvements for an enhanced version of the evaluation tool aiming at supporting fuller involvement of older nonacademic researchers in PAR studies.Originality/valueTo the authors’ knowledge, this evaluative tool is a methodological innovation in gerontology.

Lugeon Test and Grouting Application Research Based on RQD of Grouting Sections

Rock quality designation (RQD) and permeability coefficient are important reference indexes for grouting application. Based on the readily available RQD, RQD is found to have no relationship with the depth of rock stratum, and a method for calculating the mean RQD (RQDm) of long stratum is proposed, which is applied to the calculation of RQD of grouting sections. Through Lugeon and grouting tests on the grouting sections, RQDm of the grouting sections is found to be directly related to the average permeability coefficient, permeability, and units of grouting per amount of rock mass. It is found that RQDm has a symmetrical relationship with permeability and grouting volume as well as a negative exponential correlation with unit grouting volume and average permeability coefficient. According to the curve of RQD varying with depth, the grouting amount at different depths can be obtained by using the fitting formula of unit grouting amount and RQDm.

Analysis of the Perceptions Shared by Young People about the Relevance and Versatility of Religion in Culturally Diverse Contexts

This paper analyses the relevance of religion for adolescents in the realm of peer relationships, both within and outside of educational institutions. The sample consisted of 385 young individuals attending different Secondary Education institutions located in a Spanish province characterized by its cultural diversity. The tool used to collect the information was the REDCo questionnaire. The results of the data analysis indicate that young people confer a certain relevance to religion on an internal and personal level, and that they attribute a historical value to it as a discipline. They also relate the versatility of religion to changing processes regarding beliefs and belonging to a religious community. Therefore, dialogue becomes the key tool for social cohesion in multicultural societies beyond mere tolerance, creating spaces for mutual transformation and generating a symmetrical relationship between the “Self” and the “Other”.

Evaluation of the Symmetrical and Asymmetrical Causality Relationship Between Bitcoin Energy Consumption and Stock Values of Technology Companies

Energy production is a phenomenon that has always preserved its importance for the history of humanity, as well as where the energy is spent and its consumption are also important. This study examined the causality relationship between Bitcoin energy consumption and Apple, Dell Technologies, Lenova Group, HP, Quanta Computer, Compal Electronics, Canon, Wistron and Hewlett Packard Enterprise has been taken into account to represent technology companies’ stock market. In the analysis, daily price data for the period 12.02.2017-07.02.2021 were used. Toda-Yamamoto (1995) symmetric causality test and Hatemi-J (2012) asymmetric causality test were used for used to determine the relationship between Bitcoin energy consumption and technology companies’ stock values. According to the results of the Toda-Yamamoto (1995) causality test, it has been found that there is a causality from Bitcoin energy consumption to Apple's stock value; according to the Hatemi-J (2012) asymmetric causality test results, it has been determined that there is a causality from Bitcoin energy consumption positive shocks to Apple, Dell Technologies, Lenova Group, HP, Quanta Computer, Compal Electronics, Canon, Wistron and Hewlett Packard Enterprise stock values negative shocks and from Bitcoin energy expenditure negative shocks to Hewlett Packard Enterprise negative shocks. According to the results of the study in general, it is seen that the change in Bitcoin energy consumption has an effect on the firm returns of the companies that sell the necessary tools for bitcoin energy production. From this, it can be commented that bitcoin mining is also effective on the stock returns of technology companies as well as many financial factors.

Does foreign direct investment asymmetrically influence carbon emissions in sub-Saharan Africa? Evidence from nonlinear panel ARDL approach.

In recent decades, the relationship between foreign direct investment (FDI) and carbon emissions has garnered the extensive attention by researchers and governments across the globe. Also, for most part, empirical studies on this nexus have assumed a symmetric relationship through the imposition of linear specifications. However, such relationships do not account for asymmetries in the impact of FDI on carbon emissions. In the case of sub-Saharan Africa, such relationships are crucial and need more careful analysis given the important role FDI plays in the development of the sub-region. Thus, this paper examines the asymmetric effect of FDI on carbon emissions in 41 selected sub-Saharan African countries spanning from 1996 to 2018. In order to decompose FDI into positive and negative partial sum and examine possible asymmetric effects of the variables on carbon emissions, we used the panel nonlinear autoregressive distributed lag (NARDL) approach. This method accounts for cross-sectional variances. Our results show that in the long run, a positive shock in FDI increases carbon emissions while a negative shock lowers them. Our results also show that carbon emissions respond asymmetrically to changes in FDI. It is recommended that comprehensive investment policies aimed at encouraging clean technology and environmentally friendly investments be implemented to ensure environmental sustainability.
