Authors: Otieno Denish Ouko , Kirigha Faith Halima , Akwala Alfred Okoth
Published: October 2020

Facebook is regarded as a popular social network in Kenya more so among the youth besides other sites like Instagram and Twitter. A study conducted by World Wide Web Foundation revealed that more than one in every five women in Kenya have experienced cyberbulling. Such study results justifies that the internet is rife with harassment with more women bearing the brunt as compared to men. The main objective of the study was to establish forms of cyber-bullying among young women between 25 to 35 years old on Facebook platform. It was established that unwanted trolls, doxing, and sexual harassment were the dominant cyberbullying trends on Facebook among young women in Kenya with men being the highest perpetrators of cyberbullying than women. It was also established that there is lack of awareness among young women on Facebook Safety, which is a resource developed by Facebook for reporting inappropriate content and help protect people who may be feeling self-injury due to cyberbullying on Facebook.

Cross-Cultural Study of Trust Types in Sharing Economy Organizations
Authors: Li Jialei , Meng Tao , Li Chunying
Published: October 2020

The sharing economy has developed very quickly. However, organizations like Airbnb and Uber have encountered crisis of trust. Academia still does not know what is the type of trust in sharing economy organizations. Therefore, the authors designed two studies, used data from Airbnb, to test 2 hypotheses: (1) the level of inter-organizational trust in sharing economy organizations is relatively positive to the level of participation, and (2) the price of the product or service being shared is relatively negative to the level of participation. The results find out that consumers are more willing to choose non-shared renting methods in China, yet the opposite in America. Under both conditions, price is an important moderator. This shows that the role of trust in China is mainly inter-organizational trust, but interpersonal in America. The theoretical contribution is to reveal the type of trust in the sharing economy organizations, collaborative relations and studies of Airbnb.

This research investigates the outcomes of school communities who leverage an antiracist political agenda to address the racial achievement gap. In New York City, the Equity and Excellence for All agenda is a series of programs and mandates designed to improve student achievement through an antiracist, equity driven lens. This chapter examines policy implementation with an understanding of preexisting school culture conditions that impact policy efficacy. Toward this goal, this research is part of a larger body of work that prioritizes data from the vantage point of students, teachers, and school leaders. A multi-methods study, this research leverages a priori quantitative analysis to articulate distinction in school race culture and then qualitative analysis to capture the counter narrative of the marginalized who are situated in the educationally stratified spaces.

Risk Management
Authors: Zabalawi Eman A. , Bakhouche Abderazak , El Chaar Randa
Published: October 2020

The chapter covers practical risk managers' points during the planning stage of entrepreneurship to integrate into decision making and core business processes. The chapter includes three risks and how to improve the integration of risk management into organizational culture grouped into three high-level objectives. First, strategic risks include the study of competitors, macroeconomics with its industry changes. Second, financial risks such as the business return of investment and forecasting, customer payments, loan interest charges, and liquidity. Access to finance featured prominently in several studies as a constraint on SME development. The third is the operational risks and internal analysis that includes legal compliance, breakdown of essential equipment, employee mismatch, partnership, information technology, external events, and supply chain reliability. It is vital to establish an organizational culture where risk management is a daily component activity.
Resourcing an Ethical Global Issues Pedagogy With Secondary Teachers in Northern Europe
Authors: Pashby Karen , da Costa Marta , Sund Louise , Corcoran Su Lyn
Published: October 2020

In this chapter, the authors report on a participatory research project with secondary school teachers in England, Finland, and Sweden that aimed to explore the possibilities for ethical global issues pedagogy in the classroom. The project had three integrated stages: 1) development and delivery of a workshop for teachers based on a synthesis of theoretical work in critical global citizenship education and environmental and sustainability education, and introducing Andreotti's (2012) HEADSUP tool; 2) classroom visits and reflective interviews with teachers where the workshop material was applied and adapted; and 3) drafting, reviewing, piloting, and publishing online a resource to support teacher practice. Findings show teachers are inspired and committed to engaging with deep ethical pedagogical approaches to global issues. However, in order to be able to take up critical approaches in the classroom, teachers require resources and spaces where they can engage with theory and research, reflect, experiment, and exchange information with other teachers.
Development Education in the Age of COVID-19 and Climate Change
Authors: McCloskey Stephen
Published: October 2020

Development education (DE) is a radical learning pedagogy that combines analysis, discussion, and action to engage the learner in active citizenship toward positive social change. This chapter discusses the contribution that DE and other related ‘educations' can make to mitigating the climate crisis and addressing the growing levels of poverty and inequality in the global North and South. Central to this discussion is the neoliberal economic model that has driven ‘development' since the 1970s and placed the needs of the market above the social needs of citizens. This has become particularly apparent during the coronavirus pandemic which has overwhelmed the health services of countries across the world. The chapter argues for a more sustainable form of development based on de-growth and a Green New Deal.
(A)Esthetics and Violence Psychology
Authors: Ceyhan Ezgi Gül
Published: October 2020

The two concepts, aesthetics and violence, produce each other and give an idea of the individual's object orientations. Therefore, it seems necessary to analyze these two concepts. In this chapter, violence and aesthetics are discussed on the assumption that violence and aesthetics affect the inner backwardness and tension under the advanced activism of the individual, how violence and aesthetics work abstractly. The performing arts chosen to analyze the concepts of violence and aesthetics are discussed to understand this area. The chapter aims to look at the foundations of the relationship between aesthetics and violence and open a place of thinking in the literature within the framework of a new meaning. The two concepts to be used in this study are used outside of the basic meaning of violence and aesthetics.
The Coexistence of Violence and Aesthetics in Performance Art
Authors: Gümüş İlknur
Published: October 2020

During the performances based on performance art, the audience and the performers are in interactive communication. Along with the performance art, artistic communication becomes symmetrical and the artist with the audience share an emotional and mutual sharing. Performance art is an important example of artistic communication model. In addition, the art of performance opposes the social, physical, spiritual borders we are in, and deals with issues such as supervision policies, religious and ideological exploits, identity and gender discrimination, diseases, unemployment, economic and ecological problems. It is seen that performance art frequently uses the aesthetics of violence while addressing these issues. In this chapter, two important representatives, who use violent of aesthetics in their performing arts, Marina Abramovic and Hermann Nitsch, will be the subjects.
Myths, Tales, and Symbols
Authors: Agocuk Pelin , Ciftci Dilan
Published: October 2020

Since the emergence of humanity, symbolic communication has been considered a creative language that has attracted the attention of many different disciplines. Due to the indifference of culture, the phenomenon of folk tales and legends claims that there is more space in literature. The purpose of this study is to create a knowledge base for spatial and cultural memory and to define the cultural heritage of Anatolia, which has hosted many civilizations, through historical periods. This study, which will contribute to a better understanding of the causes of cultural memory in terms of transferring stories for generations, aims to explain the relationship between space and cultural memory through Anatolian legends. For this reason, the study will explain folk tales with a semantic approach in terms of symbols and values. Within the scope of Anatolian legends, the codes and secrets of myths, fairy tales, and legends will be explained using qualitative research method and document analysis technique, and the relationship between space and cultural memory will be examined.
Meaning of Space in Cinema
Authors: Arısoy Eda , Gökmen Esma
Published: October 2020

Spaces are the basic components of communal and cultural life. Beyond its sheer physicality, a space finds its existence in the communal living space through the meaning universe it creates. The conceptual framework of space and place, therefore, feature lexical distinctions; what distinguishes space or perhaps makes it superior is the fact that humans can interact with it. A place gains spacious characteristic via relations and meanings attributed to it. While the physical presence of a space is interpreted merely at the geometrical level, the meaning created in the space can be best revealed by scrutinizing individuals and relations which gain existence there. This is what depicts and personalizes the space. In this context, this study aims to examine how space relates with the cognitive aspect of cinema and in what way it contributes to the meaning creation in cinema as well as to reveal its connection with the ideology of the film.
Ottomentality as Technology of Self
Authors: Turgut Hasan , Yayla Neslihan
Published: October 2020

Extreme-right populist tendencies are getting stronger day by day. Although there are various factors that make the extreme-right populist tendencies stronger, the fact that cannot be ignored is that these tendencies must be reproduced discursively (history, culture, etc.) by the ruling power structures. Today, digital media and especially games are the primary areas where this reproduction process is most visible. Mobile games, in particular, turn into dominant cultural phenomena related to daily life beyond leisure, entertainment, and mind refreshing functions. Within this view, it is claimed that the mobile games based on the historical narratives in Turkey work as technology of self to contribute to the discourse of neo-Ottomanism. In order to test this claim, the three most downloaded mobile games (Game of Sultans, Magnificent Ottoman, and Age of Ottomans) in the Appstore and Android markets are selected as examples, and the aesthetic production realized through the structural elements of the game will be analyzed.

Authors: Bozan Mehmet Arif , Akcay Ahmet Oguz , Karahan Engin
Published: October 2020

This study aims to examine students' knowledge of shapes as well as the views of the students and their teachers about the use of AR applications in teaching and learning geometry in second-grade mathematics lessons. A convergent parallel mixed methods research design was employed. The data collected for this study come from tests on the knowledge of shapes, as well as semi-structured interviews with students and their teachers and open-ended questionnaires. The participants of the study comprised three primary school second-grade teachers and the students from these teachers' classrooms. The quantitative data were analyzed via paired sample t-test, while the data derived from the qualitative sources were analyzed by using a content analysis method. The results show that the AR application in the second-grade mathematics lessons positively affected the students' knowledge of shapes. In addition, both students and their teachers considered AR technologies as a facilitator for learning geometrical shapes.
Religious and Spiritual Tourism
Authors: Sousa Bruno Barbosa , Castro Cristina , Luís Maria Emília , Lopes Paulo
Published: October 2020

Over the years there has been an increase in competition among tourism destinations, leading to the need for a deeper understanding about the tourism realm, impact, and management. Tourism has expanded its scope, reflecting an increasing recognition in the academic community paralleled by the application of interdisciplinary concepts and methods. Indeed, research in tourism has been studying its various implications from a multitude of perspectives and with interdisciplinary insights. Areas in tourism research entail planning of tourism destinations, local development, environmental impact, territorial brand management, and tourist loyalty. With new motivations, new niches are created, and it is one of those niches that the authors address in this work, namely, spiritual tourism. Spiritual tourism derives from religious tourism because it is linked to spiritualism and is associated with wellness tourism. This manuscript aims to present the importance of spirituality in the context of tourism (Alentejo, Portugal). In the end, new lines of research will be presented for the future.
Challenges of Religious Tourism in the Conflict Region
Authors: Pipia Salome , Pipia Saba
Published: October 2020

Pilgrimage has historically and traditionally been considered a physical journey, in order for one to know the truth and visit a place that has sacred and holy meaning. In the modern world, with the development of technology and the process of globalization, territorial boundaries are slowly shrinking, making traveling much easier, and hence, with traditional tourism, of course, religious tourism has also progressed. In the research, the authors consider the challenges that religious tourism has in the modern world, especially the case of Jerusalem. They mainly focus on two variables, legal status of Jerusalem and political instability as problems, which are associated with the development of tourism in a conflict environment. They hypothesis is that unlike conventional tourism, religious tourism has a much greater chance of overcoming various challenges and developing in a conflict-prone and volatile environment.
Mystical Tibet Today
Authors: Kotsotsashvili Madlein V.
Published: October 2020

Tourism is one of the fastest-growing industries in the world. Currently, it provides 10% of the world's income and employs one-tenth of the total workforce. World Tourism Organisation (WTO) estimates that by 2020 1.6 billion people will travel around the globe and an estimated income of $1.5 billion will be generated from these activities. With all these financial outcomes, tourism can provide great opportunities for the local economies. The sacred geography of the Tibetan region and the sacred Mount Kailas combines the origins of the world's four religions. For several centuries Tibet was closed to foreign visitors and tourists. This is explained not only by the complex geographical location. Tibet's isolation was largely driven by both Tibetan rulers and Chinese policy.
Religious Tourism in Africa's Global South
Authors: Henama Unathi Sonwabile , Apleni Lwazi
Published: October 2020

International tourist arrivals are projected to surpass 1.8 billion by 2030 on the back of rapid growth in emerging tourism economies. Tourism has emerged as an economic messiah for a plethora of countries in Sub-Saharan Africa. It has emerged as a cost-effective means by which countries can diversify their economies, especially countries with low economies that depend on agricultural products to diversify their economies. Religious tourism can contribute to deeper economic benefit for a destination. The synthesis of literature adds to the paucity of academic gaze on religious tourism in Southern Africa. The synthesis takes the reader on a religious tourism journey that includes African spirituality, Pentecostal Christianity, and the interface between Africans spirituality and Christianity. These areas are neglected in the academic gaze and are outside the tourism beaten track, and these forms of religious tourism bring in much needed economic activities for areas on the tourism fringe.
Types of Religious Tourism
Authors: Ijaz Aniqa
Published: October 2020

Religious tourism is considered as one of the interesting and oldest areas of research in the field of tourism. The process of observing and practicing the religious activity during the visit of any sacred place combined with the zeal of faith in the heart of practitioner is categorized as religious tourism. Many of the researchers have explained its different types in their own perspectives. Within the boundaries of modern scientific society, modern religious tourism can be classified into two major types. One is pilgrimage and the other one is intellectual learning excursions. The second main category has two branches. These intellectual learning excursions are based on two mottos of the tourists. One is regarding the scientific know-how, and the second one is regarding attending the religious-cultist events.
Proposals for Social Pedagogy and the Best Political Practices From the Crown of Aragon
Authors: Roig-Vila Rosabel , Merma-Molina Gladys , Gavilán-Martín Diego
Published: October 2020

The authors analyze the figure of the Franciscan Francesc Eiximenis, and especially his Regiment de la cosa pública, from a reflection on medieval pedagogy and politics. Likewise, they establish meeting points between the thought, the words and the pedagogy of Eiximenis and those of other authors. So, the chapter draws a chronological-analytical line between him and other relevant figures of the 13th through the 16th centuries, such as Saint Thomas Aquinas, Beatus Ramon Llull, Niccolò Machiavelli, (Saint) Thomas More, Saint Vincent Ferrer, and Joan Lluis Vives.
Catalan “Sedition” in the 17th Century
Authors: Biosca Antoni
Published: October 2020

The Latin poem Seditio Catalaunica, still unedited and lacking studies and translation, is a clear example of the anti-Catalan mentality typical of the Reapers´ War in 17th-century Spain. In this poem, kept in a 17th-century MS held at the Biblioteca de la Real Academia de la Historia, Madrid, we can find clear references to Catalonia´s and Catalans´ guilt in the war, as well as accusation of treason and sedition. The epic poem, composed of over 1,200 Latin hexameters, is accompanied by five brief that insist on the same idea. This accusation of sedition has also served in recent times to try in a court of law pro-independence Catalan leaders in 2019, so that we can analyze this poem as a precedent of Spanish politics with regard to Catalonia.
Francesc Borrull and Bartomeu Ribelles
Authors: Escartí Vicent Josep
Published: October 2020

In 1810, two works were printed in Valencia that defended the validity of the Valencian foral system established in our lands as a result of the conquest of James I when it was abolished since 1707, after the defeat of Almansa. These are the Discurso sobre la constitución que dio al reyno de Valencia su invicto conquistador, el señor don Jayme Primero by Francesc Xavier Borrull and the Memorias histórico-críticas de las antiguas Cortes del reyno de Valencia, a work by the Dominican friar Bartolomé Ribelles. This chapter analyzes the interests of those authors and places these works within the political context of the Spain of the moment, invaded by the Napoleonic troops.
A Study of References in Contemporary Collections of Valencian Folktales
Authors: Vidal Vicent
Published: October 2020

The publication of folktale collections in the Valencian Country becomes especially notable from the 1980s. Many such publications are aimed at children and young readers, but some are targeted at general adult, or even specialized, audiences. Collections often include explicit references to authors and folklorists who serve as models or references to varying degrees. Sometimes comparisons are made between the plots of specific folktales, sometimes the reference is in the form of a scholarly commentary while at other times the reference serves to locate the collection within a wider literary tradition (Valencian, Catalan, European, international, etc.). The purpose of this chapter is to study these references in Valencian folktale collections after the 1980s, because not only do such references play a fundamental role in understanding and researching folktale collections, but they also make it possible to analyze the way—and the extent to which—these publications identify themselves within a particular linguistic, literary, or cultural framework.
A Resilient Steady Clustering Technique for Sensor Networks
Authors: Jain Khushboo , Kumar Anoop , Vyas Vaibhav
Published: October 2020

In wireless sensor networks (WSNs), each sensor node is proficient to transmit data packets dynamically deprived of any constraint of fixed infrastructure. Sensor nodes (SNs) intermittently travels within the network from one cluster to another, which makes the network topology unsteady, uncertain, and unreliable. Consequently, it turns to be an immense challenge to sustain network stability and durability. In this work, the authors have presented a resilient steady clustering technique (RSCT) that will maintain durability and steadiness to the sensor network by reducing the unnecessary and avoidable cluster head (CH) changes and minimizing clustering and networking overheads. In the presented technique, they have introduced a new SN that acts as a standby node (SBN) in the cluster. This SBN performs the tasks of CH whenever the actual CH moves from the cluster. Later the CH re-elect the new SBN. This process keeps the network available and serviceable without any interruption. The decision for selecting the CH and SBN depends on the optimal CH threshold function and an energy threshold function.
A Novel Approach for Business Process Model Matching Using Genetic Algorithms
Authors: Abdelkader Mostefai , Rodríguez de Guzmán Ignacio García
Published: October 2020

This paper formulates the process model matching problem as an optimization problem and presents a heuristic approach based on genetic algorithms for computing a good enough alignment. An alignment is a set of not overlapping correspondences (i.e., pairs) between two process models(i.e., BP) and each correspondence is a pair of two sets of activities that represent the same behavior. The first set belongs to a source BP and the second set to a target BP. The proposed approach computes the solution by searching, over all possible alignments, the one that maximizes the intra-pairs cohesion while minimizing inter-pairs coupling. Cohesion of pairs and coupling between them is assessed using a proposed heuristic that combines syntactic and semantic similarity metrics. The proposed approach was evaluated on three well-known datasets. The results of the experiment showed that the approach has the potential to match business process models effectively.
A Study of Antecedents of Switching Cost and Customer Retention in Social Commerce
Authors: Choi Youngkeun
Published: October 2020

The focus of this study is on how switching costs engages the customer to stay. By proposing the concepts of switching costs as different ways to provide psychological experience, this study develops a model that explores the antecedents of switching cost and its role in explaining customer retention in social commerce. For this, this study surveys 352 consumers using social commerce in Korea and analyzes the data using PLS-SEM. In the results, first, interactivity, sociability, social tie, and social identity among all of the sub-factors of switching cost increase switching cost. Second, switching costs increases customer retention. Finally, interactivity and social identity among the antecedents of switching costs increase customer retention through switching costs. The findings contribute to research on social commerce by paying scholarly attention to the psychological perspective characterized by switching costs.
Islamic Leadership Model and the Burden of Terrorism and Leadership in Nigeria
Authors: Uthman Ibrahim Olatunde
Published: October 2020

Despite the efforts of the Nigerian government at tackling the problems of terrorism and corruption, the terrorist activities of the Boko Ḥarām added to those of herdsmen, cattle rustlers, farmers, cultists, and militias who kill, vandalize, rob, rape, and kidnap with impunity all over the country have virtually destroyed the country, especially Northeast Nigeria. Its tourism industry has virtually gone into extinction in addition to the challenges of human, arms, and drugs trafficking; money laundering; child soldiers; and internally displaced persons in the region. All these take place while the country is also confronting the challenges of corruption. In what ways has Muhammadu Buhari administration tried to free Nigeria from terrorism and corruption? How are the challenges of terrorism and corruption tied to the development of the country? What role can Islamic leadership model play in bringing an end to these multifarious challenges ravaging the country? These are some of the questions that this papers answers using the leadership model of the Sharī‘ah.
Discrete Total Variation-Based Non-Local Means Filter for Denoising Magnetic Resonance Images
Authors: Joshi Nikita , Jain Sarika , Agarwal Amit
Published: October 2020

Magnetic resonance (MR) images suffer from noise introduced by various sources. Due to this noise, diagnosis remains inaccurate. Thus, removal of noise becomes a very important task when dealing with MR images. In this paper, a denoising method has been discussed that makes use of non-local means filter and discrete total variation method. The proposed approach has been compared with other noise removal techniques like non-local means filter, anisotropic diffusion, total variation, and discrete total variation method, and it proves to be effective in reducing noise. The performance of various denoising methods is compared on basis of metrics such as peak signal-to-noise ratio (PSNR), mean square error (MSE), universal image quality index (UQI), and structure similarity index (SSIM) values. This method has been tested for various noise levels, and it outperformed other existing noise removal techniques, without blurring the image.
High-Fidelity CFD Validation and Assessment of Ducted Propellers for Aircraft Propulsion
Authors: Zhang Tao , Barakos George N.
Published: October 2020

This paper presents validation and assessment of ducted propellers for aircraft propulsion. Numerical methods and simulation strategies are put forward, including steady/unsteady high-fidelity computational fluid dynamics (CFD) simulations and simpler momentum-based methods. The validation
and comparisons of the methods are made using a ducted propeller proposed by NASA. Simulations are also performed and analyzed at extended advance ratios, blade pitch setting, and cross-wind angles. Comparisons are also made with open propeller counterparts. The ducted propeller shows superior
performance over its unducted counterpart in hover and at low advance ratios. The major thrust gain is identified from the combination of duct leading-edge suction and the higher pressure at the diffuser exit. The propeller is off-loaded due to the higher inflow velocities. The ducted propeller
is also shown to have less intrusive wake features at low axial speeds. However, as the advance ratio increases, the duct thrust contribution becomes negative and the ducted propeller becomes deficient, due to growing high-pressure areas at the leading edge. At cross-wind, high-fidelity CFD
simulations offer accurate aerodynamic loads predictions despite the complex flow features. The duct surface separation is found to be delayed due to the propeller suction, while the propeller is shown shielded by the duct, thereby suffering less from the unbalanced inflow velocities. Decomposition
of induced velocities by each part is carried out and presented. A large, nonlinear extra induction component, due to mutual interactions of the duct and the propeller, is observed and found favorable for the performance augmentation.
On the eigenvalues of quantum graph Laplacians with large complex $\delta$ couplings
Authors: Kennedy James B. , Lang Robin
Published: October 2020

We study the location of the spectrum of the Laplacian on compact metric graphs with complex Robin-type vertex conditions, also known as

\delta

conditions, on some or all of the graph vertices. We classify the eigenvalue asymptotics as the complex Robin parameter(s) diverge to

\infty

in

\mathbb C

: for each vertex

v

with a Robin parameter

\alpha \in \mathbb C

for which Re

\alpha \to -\infty

sufficiently quickly, there exists exactly one divergent eigenvalue, which behaves like

-\alpha^2/\mathrm {deg} v^2

, while all other eigenvalues stay near the spectrum of the Laplacian with a Dirichlet condition at

v

; if

\mathrm {Re} \alpha

remains bounded from below, then all eigenvalues stay near the Dirichlet spectrum. Our proof is based on an analysis of the corresponding Dirichlet-to-Neumann matrices (Titchmarsh–Weyl

M

-functions). We also use sharp trace-type inequalities to prove estimates on the numerical range and hence on the spectrum of the operator, which allow us to control both the real and imaginary parts of the eigenvalues in terms of the real and imaginary parts of the Robin parameter(s).
Constructing separable Arnold snakes of Morse polynomials
Authors: Sorea Miruna-Ştefana
Published: October 2020

We give a new and constructive proof of the existence of a large class of univariate polynomials whose graphs have preassigned shapes. By definition, all the critical points of a Morse polynomial function are real and simple and all its critical values are distinct. Thus to any Morse polynomial we can associate an alternating permutation called
Arnold snake
, given by the relative positions of its critical values. Our main result is an effective construction that can realise any separable alternating permutation as the Arnold snake of a Morse polynomial.
A generalized one phase Stefan problem as a vanishing viscosity limit
Authors: Wang Kelei
Published: October 2020

We study the vanishing viscosity limit of a nonlinear di¤usion equation describing chemical reaction interface or the spatial segregation interface of competing species, where the di¤usion rate for the negative part of the solution converges to zero. As in the standard one phase Stefan problem, we prove that the positive part of the solution converges uniformly to the solution of a generalized one phase Stefan problem. This information is then employed to determine the limiting equation for the negative part, which is an ordinary differential equation.

Has COVID-19 Changed Exchange Rate Resistance to Shocks?
Authors: Narayan Paresh Kumar
Published: October 2020

In this note, we propose the hypothesis that COVID-19 has influenced the Yen-US dollar exchange rate’s resistance to shocks. We propose a time varying unit root model and unravel that prior to the pandemic, the Yen was non-stationary while during the pandemic it became mostly stationary, suggesting that shocks to the Yen are having a transitory effect. We, as a result, conclude that COVID-19 has changed the resistance of the Yen to shocks.
Comparing Comparisons in Muslim Polemical Writings from Christian Iberia and Exile: Muḥammad al-Qaysī’s Kitāb Miftāḥ al-Dīn and the Anonymous Tratado de los dos caminos
Authors: Colominas Aparicio Mònica
Published: October 2020

Comparison figures prominently in the polemics of the Muslim, Christian, and Jewish inhabitants of the Iberian Peninsula in premodern and early modern times. Its pervasiveness as a figure of thought in their sources raises the question of variety in regard to comparison—that is, the multiple expressions of comparison as well as its numerous uses—particularly in the field of polemics. This paper discusses the functions of comparison in polemics as a necessary first step to advance current knowledge of comparison as a historical practice in the making of one’s identity and the definition of groups and individuals. The discussion will focus on writings by Muslims who lived in Christian Iberia. It will focus particularly on two anti-Christian polemics: that by the Tunisian author Muḥammad al-Qaysī in an as-yet unstudied Aljamiado copy (Spanish in Arabic characters); and the Tratado de los dos caminos (Treatise of the Two Roads), an early-seventeenth-century work of Islamic doctrine by the so-called “Refugee in Tunisia”. The analysis of these two works will address the most important common points and differences between their respective polemical comparisons.
THE LINK BETWEEN BANK CREDIT AND PRIVATE SECTOR INVESTMENT IN NIGERIA FROM 1980-2014

Published: October 2020

This study attempts to investigate the link between bank credit and private sector investment in Nigeria from 1980 to 2014 using Ordinary Least Square (OLS) regression procedure. The study also employs other preliminary investigations which include, unit root, cointegration and Granger causality test procedures. The OLS result indicates that the coefficients of the variables which include, banks credit to the private sector (CRPRIVAT), trade openness (OPEN), exchange rate (EXCHR) and total bank saving (BSAVING) exhibit positive signs to the dependent variable, private investment (INVEST) during the period under review, while the coefficients of two other variables, capital expenditure (CAP) and interest rate (INTR) indicate negative signs to the dependent variable. The stationarity test result shows that all the variables under consideration are stationary and integrated of order one at 5% significance level. Also, the cointegration test result indicates at most five cointegrating equations at 5% level of significance. The Granger causality test result shows that a bi-directional causality exists between banks credit and private investment and also between private investment and capital expenditure, while a uni-directional causality exists from exchange rate to private investment.Statistically, the descriptive statistics result indicates that all the variables have a positive mean values which ranges from 18.05390 to 2427052 with 34 observations.The correlation test result obtained shows that four variables, CRPRIVAT, OPEN, EXCHR and BSAVING have positive relationships with the dependent variable INVEST. The t-statistic result shows that five of the variables which includes, CRPRIVAT, OPEN, CAP, INTR and EXCHR are statistically significant at 5% significance level. The study recommends that there is a need for increased Federal government support to banks in terms of policies that would encourage lending to the private sector in Nigeria.

GRACE/GRACE-FO observed terrestrial water storage influencing global grassland growth

Land water supply for plant growth directly links the water and carbon cycles. The abundance or shortage of water storage influences plant water consumption strategies and have important implications for ecosystem drought resistance and resilience, especially for the grassland ecosystem where water is the primary factor limiting plant production. However, plant-accessible water is rarely quantified due to the lack of regional to global scale observations of deeper water storage, and the influence of deeper water supply on plant-water relation remains unknown. In this study, we evaluate the capacity of GRACE/GRACE-FO total terrestrial water storage (TWS) estimates to capture plant-accessible water supply at depth. We use ESA CCI surface soil moisture (SM) estimates to represent shallow water storage and MODIS EVI as a proxy for grassland productivity. We calculate the inter-annual correspondence of EVI against both TWS and SM over 24 GRACE mascons covering the majority of the global grassland areas. Our results show that complementary to SM measurements, TWS provides unique information about deeper water storage limiting grassland growth. We find that the seasonal change of TWS constrains plant-accessible water storage and leads to different plant-water relations in the grassland regions across the globe.
