Published: January 2021

The occurrence of faults in any operational power system network is inevitable, and many of the causative factors such as lightning, thunderstorm among others is usually beyond human control. Consequently, there is the need to set up models capable of prompt identification and classification of these faults for immediate action. This paper, explored the use of artificial neural network (ANN) technique to identify and classify various faults on the 11 kV distribution network of University of Lagos. The ANN is applied because it offers high speed, higher efficiency and requires less human intervention. Datasets of the case study obtained were sectioned proportionately for training, testing, and validation. The mathematical formulations for the method are presented with python used as the programming tools for the analysis. The results obtained from this study, for both the voltage and current under different scenarios of faults, are displayed in graphical forms and discussed. The results showed the effectiveness of the ANN in fault identification and classification in a distribution network as the model yielded satisfactory results for the available limited datasets used. The information obtained from this study could be helpful to the system operators in faults identification and classification for making informed decisions regarding power system design and reliability.
2D-CFD Analyses of Flow Controlling Plates on Gable Roof Geometry Cross-Sections for Light Air to Strong Breeze Wind Speed Classifications-an Unsteady RANS Approach
Authors: Amini Kasra , Mani Alireza
Published: January 2021

The flow field analysis has been numerically performed on the effectiveness of a flow control mechanism called the Flow Controlling Plate (FCP) on buildings. For this purpose, the gable roof geometry has been considered as a common urban element in the western residential architecture. As the justification step towards the functionality of the concept of FCPs, the 2D numerical investigation of the flow field under the realistic assumptions of atmospheric boundary layer profiles for the spectrum ranging from the so-called light air to strong breeze wind speed classifications have been performed. The CFD (Computational Fluid Dynamics) field calculations have been conveyed as an unsteady case for the flow around a bluff body, using RANS (Reynolds Average Navier-Stokes) averaging methods targeting a solution of Navier-Stokes equations of the fluid flow. The results have proven the hypotheses of the contribution of the FCPs on preventing the flow separation on a partial region of the surface and improving the boundary layer development on the rest of the gable roof facades, which have led to a drastic reduction in the convective heat transfer coefficient as well as the drag force exerted on the roof
Spatial and Security Organisation of Court Buildings: An Assessment of Selected High Court Buildings in Nigeria
Authors: Makinde Olusola Oladapo
Published: January 2021

Within the context of functional efficiency, this study assesses the spatial organisation and security of court building in Southwest Nigeria as a panacea to a design proposal for an ideal high court building. To achieve this, fifteen structural parameters were employed for measuring efficiency. These are spaces organisation, spaces standard, structural fitness, communication, noise, environmental cleanliness, building layout, privacy, visual form, security, parking spaces, acoustics system, circulation pattern and spaces allocation. Towards the realisation of these objectives, both primary and secondary data were collected. The primary data employed include field measurement, personal observation of court proceedings, oral interview and administration of 290 questionnaires to court personnel, and other court participants to elicit information on the effects of adequate security and spatial organisation. The merits and demerits of the studied area along with their photographs were also documented. The information from the questionnaires was analysed using frequency distribution tables, simple percentages and relative important index. Results revealed that the court buildings were largely inadequate to space organisation and space standard. The result shows that 90% of the respondents agreed that poor spatial organisation, inadequate security, and poor landscaping are the major shortcomings inhibiting the efficiency of court buildings, while 80% agreed that the existing structures are satisfactory only in the areas of environmental cleanliness and communication within the courtrooms. Hence, the study presented useful suggestions and recommendations.

Authors: Firdaus Rizal
Published: January 2021

This paper aims to find out Mohammad Natsir's triple helix concept and its relevance and implementation in da'i education in Indonesia. The method used is descriptive qualitative, data is taken from literature sources. The results revealed that Mohammad Natsir's trilpe helix concept was to integrate three institutions in the da'i education process, namely masjid (mosque), pesantren, and kampus (university). This concept is considered relevant to the conditions and culture in Indonesia because it has the characteristics of Indonesian culture. This concept is implemented by integrating the curriculum between kampus and pesantren, kampus and masjid. Opportunities for integration between the three institutions are increasingly open with the support of the concept of an merdeka belajar dan kampus merdeka which was proclaimed by the Ministry of Education and Culture of the Republic of Indonesia. The realization of this concept can be in the form of creating joint projects between kampus and masjid by involving students in managing mosques and managing community empowerment programs together. The implementation of the integration of the kampus and pesantrens curriculum can be carried out in the context of the transmission of Islamic knowledge and the education of the da'i character which is very conducive to being carried out in a pesantren atmosphere.

Published: January 2021

A recently recovered site of plant macrofossils, Ludvíkovice, in the České středohoří Mts. is situated on Sokolí vrch hill, belonging to the Děčín Formation (radiometrically dated to 30.8–24.7 Ma), according to regional stratigraphy. The flora has yielded a fern, Rumohra recentior, and several angiosperms, but no conifers. The prevailing foliage is preserved without cuticles. Noteworthy are records of Daphnogene cinnamomifolia, Laurophyllum cf. acutimontanum, Platanus neptuni, Sloanea artocarpites, Carya fragiliformis / C. quadrangula, Alnus rhenana, Trigonobalanopsis rhamnoides, Eotrigonobalanus furcinervis and cf. Quercus sp. Several foliage specimens of dicots could not be identified to species level, i.e., Leguminophyllum sp., Pungiphyllum cf. cruciatum and Dicotylophyllum sp. div. The fossil plant assemblage of Ludvíkovice corresponds to zonal mesophytic vegetation accompanied by riparian elements. This is corroborated by the Integrated Plant Record vegetation analysis, which reconstructs a zonal broad-leaved evergreen forest similar to the living broad-leaved evergreen sclerophyllous forest from Southern Hunan and Northern Guangxi in SE China. The vegetation thrived under a humid climate characterized by average values of MAT (14.6–24.1 °C), WMMT (24.7–28.3 °C), CMMT (2.2–18.8 °C) and MAP (979–1724 mm). The fossil flora of Ludvíkovice is similar in composition to the floras of Markvartice, Veselíčko, also from the Oligocene Děčín Formation of the České středohoří Mts. and the Hrazený hill.
Proterozoic basement and Palaeozoic sediments in the Ringkøbing–Fyn High characterized by zircon U–Pb ages and heavy minerals from Danish onshore wells

Published: January 2021

New data from the Proterozoic basement and scattered Palaeozoic sediments in the Ringkøbing–Fyn High including zircon U–Pb geochronometry, heavy mineral compositions and whole rock geochemistry is presented here to provide a frame of reference for detrital provenance studies.
The Ringkøbing–Fyn High is a WNW–ESE trending structural high including subcropping basement rocks, and the results indicate that it is a southerly extension of the Fennoscandian Shield. The zircon data show matching age distribution patterns in crystalline basement rocks obtained from two drill sites, the Glamsbjerg-1 and Grindsted-1 wells. They both record a characteristic Telemarkian accretionary event at 1.51 and 1.48 Ga and a Sveconorwegian metamorphic overprinting at 1.08 Ga.
Furthermore, the dominant age intervals in the Glamsbjerg High (1.55–1.48 Ga) and the Grindsted High (1.51–1.44 Ga) suggest that rocks of the Gothian orogeny (that ended at 1.52 Ga) are only present in the eastern part of the Ringkøbing–Fyn High. Thus, the buried basement in central Denmark may be youngest towards the west, which is consistent with the general westward age progression trend in the Sveconorwegian Orogen.
The basement breccia in the Arnum-1 well on the southern flank of the Ringkøbing–Fyn High has zircon ages (c. 1.54–1.53 Ga) that resemble those of gneiss in the Glamsbjerg High. The conglomeratic sandstone in the Ringe-1 well on the Glamsbjerg High has a dual age distribution as the matrix has late Palaeoproterozoic to early Mesoproterozoic ages, whereas the granitic clasts have a distinct middle Neoproterozoic age (c. 0.76 Ga) that may indicate an Avalonian source. The quartzite in the Slagelse-1 well on the northern flank of the Ringkøbing–Fyn High has a broad age span with late Palaeoproterozoic to late Mesoproterozoic zircon ages.
Supplementary material: Detailed documentation of U/Pb analytical procedures, results and analysed zircon spots are available below.
Glacial erratic boulders from Jutland, Denmark, feature an uppermost lower Cambrian fauna of the Lingulid Sandstone Member of Västergötland, Sweden.
Authors: Weidner Thomas , Geyer Gerd , Ebbestad Jan Ove R. , Seckendorff Volker von
Published: January 2021

Reinvestigation of glacial erratic boulders from Jutland, Denmark, and from northern Germany, has revealed a moderately diverse fauna with the trilobites Holmiella? sp., Epichalnipsus anartanus, Epichalnipsus sp. A, Epichalnipsus sp. B, and Berabichia erratica, three species of lingulid brachiopods, one hyolith species, and trace fossils comparable to Halopoa imbricata.

Comparison with faunas from the Cambrian of Scandinavia strongly suggested a biostratigraphic position equivalent to the uppermost part of the (revised) Holmia kjerulfi–‘Ornamentaspis’ linnarssoni to lowermost Comluella?–Ellipsocephalus lunatus zones sensu Nielsen & Schovsbo (2011), or the lower to middle part of the traditional ‘Ornamentaspis’ linnarssoni Zone, but probably a particular horizon and biofacies not yet discovered in Scandinavia.

Considerations of glacial transport regimes and the distribution of comparable rock units, as well as a petrographical analysis of the material from the studied erratic boulders and rocks from outcrops in Sweden, indicate that the boulders were derived from the Lingulid Sandstone Member of the File Haidar Formation and the source area is situated in the vicinity of the present-day outcrops in the Halleberg–Hunneberg area, Västergötland, Sweden.

El propósito de esta investigación es analizar el Sistema Tributario Mexicano mediante la aplicación de metodologías por órganos jurisdiccionales de la Nación. Se utilizó en la investigación una metodología jurídica, con un enfoque cualitativo, mediante el método deductivo e histórico a través de técnicas de investigación documental, tomando en cuenta la ley, la jurisprudencia y la doctrina, como fuentes formales del derecho, identificando que en el Sistema Tributario Mexicano los órganos jurisdiccionales de la nación aplican una metodología basada en los métodos de interpretación tradicionales y una metodología contemporánea basada en los derechos humanos. Se concluye que no existe una metodología otorgada en el marco normativo tributario. En razón de ello, se establece un sistema que permite agrupar los principales métodos de interpretación en materia tributaria utilizados por los órganos jurisdiccionales en dos grupos: 1) metodología de interpretación tradicional, y 2) metodología de interpretación contemporánea. La aplicación del derecho es compleja, y no hay una verdad absoluta ya sea en conceptos, palabras, definiciones.

Published: January 2021

Benchmarking is an effective method for organizations to increase their productivity, quality of products, reliability of processes or services. The organization may make a comparison between its performance and that of the peers from benchmarking, and recognize their advantages as well as disadvantages. The main objective of the present systematic literature review has been the study of DEA benchmarking process. Therefore, it examined and gave a summary of various DEA models applied worldwide to improve benchmarking. Accordingly, a list of published academic papers that appeared in high-ranking journals between 2003 and February 2020 was collected for a systematic review of the DEA benchmarking application. Consequently, the papers selected have been classified according to year of publication, purpose of research, outcomes and results. This study has identified eight major applications including: transportation, service sector, product planning, maintenance, hotel industry, education, distribution and environmental factors. They take up a total of 82% of all application-embedded papers. Among all the applications, the highest recent development has been in both the transportation and service sectors. Results showed higher potential of DEA as a suitable evaluation method for the further benchmarking researches, wherein the production feature between outputs and inputs has been practically lacked or very hard to obtain.
New normativity and reproductive choice: an attempt at comprehension
Authors: Bronfman Svetlana A.
Published: January 2021

The article discusses two “special types” of reproductive choices – combating infertility through assisted reproductive technologies and voluntary childlessness. Particular attention is paid to the phenomenon of voluntary childlessness. Basing on the analysis of public opinion polls, reconstruction of historical realities of the second half of XX century, normogenesis studies, new psychodynamic theories of transgenerational transmission of traumatic experience, and philosophical ideas of intentionality of acceptance and hospitality, the author analyzes the existing reproductive practices in their connection with procreative norms. The reasons for the increasing spread of voluntary childlessness, according to the author of the article, are largely connected to the transgenerational transmission of experience of violence. The author’s hypothesis is based on psychodynamic ideas about transgenerational trauma and perverse maternal attitude and is that the spread of the voluntary childlessness in the generation of the 1990s may be caused by the impossibility of hospitality, acceptance, and vulnerability due to the lack of failure of the maternal functionary as a container and the lack of introjects of loving and guiding parent figures (“empty superego”). Thus, the new “shapeless” normativity, creating the illusion of “freedom to be oneself”, may prove to be a projection of a split, lifeless and empty collective unconscious superego, generated by a culture of violence that requires moral content, which has been abolished.

This paper studies the mixed passive and $ H_{\infty} $ performance for uncertain neural networks with interval discrete and distributed time-varying delays via feedback control. The interval discrete and distributed time-varying delay functions are not assumed to be differentiable. The improved criteria of exponential stability with a mixed passive and $ H_{\infty} $ performance are obtained for the uncertain neural networks by constructing a Lyapunov-Krasovskii functional (LKF) comprising single, double, triple, and quadruple integral terms and using a feedback controller. Furthermore, integral inequalities and convex combination technique are applied to achieve the less conservative results for a special case of neural networks. By using the Matlab LMI toolbox, the derived new exponential stability with a mixed passive and $ H_{\infty} $ performance criteria is performed in terms of linear matrix inequalities (LMIs) that cover $ H_{\infty} $, and passive performance by setting parameters in the general performance index. Numerical examples are shown to demonstrate the benefits and effectiveness of the derived theoretical results. The method given in this paper is less conservative and more general than the others.

Nonlinear Bresse-Timoshenko beam model with thermal, mass diffusion and theormoelastic effects is studied. We state and prove the well-posedness of problem. The global existence and uniqueness of solution is proved by using the classical Faedo-Galerkin approximations along with two a priori estimates. We prove an exponential stability estimate under assumption $ (2.3)_{1} $ and polynomial decay rate for solution under $ (2.3)_{2} $, by using a multiplier technique combined with an appropriate Lyapuniv functions.
Commitment Devices for Health
Authors: Savani Manu M.
Published: January 2021

This chapter examines how and why commitment devices have been used for weight management and frames research priorities going forward. A theoretical framework drawing on Thaler and Shefrin motivates the use of commitment devices to change health behaviours. An original taxonomy separates commitment devices into three distinct types. A review of the empirical literature, with a focus on unexpected findings that defy theoretical predictions, indicates that commitment devices (1) can have positive effects on health behaviours, but (2) can also have unintended effects, which warrants further research attention to under-theorised issues of ‘commitment overload' and ‘moral licensing', and empirical testing of online commitment strategies. The COVID-19 pandemic emphasises the need for innovative but evidence-based digital health interventions. The chapter closes with suggestions for policymakers considering commitment devices for preventative health behaviours.
Overcoming Challenges to Long-Term Financing
Authors: Mohamed Hazik
Published: January 2021

A concern that has emerged repeatedly in the support for long-term sustainable development is the insufficient availability of long-term finance for projects such as infrastructure. This chapter considers some of the possible strategies to overcome obstacles (cognitive or otherwise) to ensure the provision of long-term financing. The author discusses several behavioral interventions to surmount hurdles both from the demand and supply sides as well as creating enabling environments for better access to finance. This effectively requires challenging the rationale underlying private financial flows that are driven by short-term profits and rents, and strengthening mechanisms for mobilizing and allocating both domestic and external finance for value creation and development over a longer time horizon. It also involves properly designed projects that contractually distributes risks and shares returns within economically rational financing structures and create the right incentives for the various partners.
The Paradox of Increasing Women's Space and Influence in Public Life in Africa
Authors: Essien Essien D.
Published: January 2021

Although women in Africa have become socially and fairly economically visible of late, African women have not been as politically noticeable as their male counterpart. Yet knowledge of their interest and expectations has made them serve as appendages to men or become actors on the sidelines of public space. This chapter takes a look at the different ideological and political interest where women's involvement in politics is mostly dictated by men. It explores African women's emerging public space and influence in politics and political participation through the office of the first lady.

Is Online Learning the Future of Global Higher Education?
Authors: Lemoine Pamela A. , McElveen John P. , Waller Robert E. , Richardson Michael D.
Published: January 2021

Technology for learning and globalization make the business of global higher education more complicated and competitive each day particularly in the unfolding pandemic of COVID-19. Innovation and change in global university instruction require adaptive technologies in response to the demands of a knowledge economy where students are engaged in rapid technology acclimatization in a constantly changing world. As the beginning of the third decade of the 21st century unfolds, significant changes are taking place in global universities to accommodate the needs of more students, different students, and challenged students. The global pandemic has forced most of the global higher education community to offer instruction through online learning. Although universities extensively use e-learning, distance learning, online education, remote learning, or some other form of technology-driven education currently, what are the prospects of online learning in the future after the pandemic?
How Is Your Connection?
Authors: Rivers Rebeqa
Published: January 2021

Traditional course design assumes a synchronous, in-person learning environment and relies on a skilled instructor to observe nonverbal communication and guide interactions between learners. However, the nature of online learning has changed instructor-student connections so that providing real-time, guided interactions and feedback are not always practical. The loss of these interactions has particularly affected social and emotional learning (SEL), or how people recognize and manage emotions, empathize with, and relate to others, and make responsible decisions. SEL—popularly known as emotional intelligence, EI, or EQ—has gained recognition as the foundation of vital “soft skills” that contribute to improved job satisfaction, performance, and productivity. When institutions simply convert in-person curricula to digital, the resulting online courses often do not account for the loss of real-time SEL and metacognitive guidance from an instructor. This chapter provides guidance on how to integrate SEL into the design of online courses.
Transitioning a Methods Course to Online in a Teacher Education Program That Is Not Fully Online
Authors: Arrington Nancy McBride
Published: January 2021

The transition of an undergraduate course to fully online is examined through the lens of a professor who revised the platform for the course and through the perspectives of preservice teachers participating in a hybrid version of the course in their teacher education program which is not offered fully online. Benefits of flexible student schedules and meaningful discussion participation emerged, indicating that preservice teachers can navigate learning modules and benefit from an online course offering. Challenges of implementing teamwork in the online environment arose throughout the semester of implementation, indicating a need for improvements/revisions. These lessons learned from this case study contribute to a systematic approach to transitioning from offline to online courses and augment the literature base of the experiences and appropriateness of online preservice teacher education courses.
A Multi-Perspective Theoretical Analysis to Web Accessibility
Authors: Peixoto Carlos , Branco Frederico , Martins José , Gonçalves Ramiro
Published: January 2021

Accessibility has become increasingly important in information technology, particularly due to legislation pressure to make affordable public services to all. Being end-users and software companies those who have direct contact with accessibility problems, other stakeholders are committed to defining methods and change mentalities in Web accessibility implementation. In addition to a conceptual definition, this chapter presents entities views with responsibilities in the area, taking into account their work done in the past and the prospects for future. The understanding of the interaction between all these perspectives will help to realize the way it will go, which carries with it great challenges and opportunities, widely explored in this work.
Challenges to Business Models in the Digital Transformation Context
Authors: Fernandes da Anunciação Pedro , Esteves Francisco Madeira
Published: January 2021

The digital transformation of the economy and society itself is pushing the economic organizations to processes. Multiple digital technologies like data analytics, enterprise mobility, social networks, cloud computing, robotics, block chain, and internet of things (IOT) are pushing radical changes in the ways of working (WoW). People with strong technological skills are demanding changes to organizations towards two-way business interaction in order to meet the needs and expectations. But consumers who are technology users expect new information and knowledge products and services based on technological potential. It remains to the organizations to define strategies for this transformation, seeking to adapt their organizational and information systems to this new paradigm of digital transformation.
Design Science Research to Produce Instrumental Knowledge for Evidence-Based Practice in OCD
Authors: Ernst van Aken Joan
Published: January 2021

Evidence-based practice (EBP) is a promising approach to improve professional action. EBP is the use of the best available knowledge in professional problem-solving, in particular the best available knowledge produced by research. EBP has much promise for organizational change and development (OCD). However, for successful EBP, one needs a well-developed knowledge base of instrumental knowledge (i.e., knowledge-to-act). Unfortunately, academic OCD research is strong in developing conceptual knowledge (i.e., knowledge-to-understand) but rather weak in instrumental knowledge. In this chapter, design science research (DSR) is discussed: a research strategy to develop instrumental knowledge in the form of designs for effective interventions, processes, or systems to improve present practices. These designs are developed through experiential learning by executing a number of problem-solving projects in the messy “swamp of practice,” often executed in partnerships with professionals. Embedded-in-action theories can be powerful inputs for EBP, thus improving the practice of OCD.
Organizational Learning and Change
Authors: You Jieun , Kim Junghwan , Lim Doo Hun
Published: January 2021

This chapter discusses organizational learning as a strategic approach for organizational change. In the face of turbulent and uncertain environments, continuous involvement in organizational change is necessary. However, most organizations encounter resistance to change, thus fail to accomplish organizational change despite change efforts. Previous literature explains that resistance to change results from cognitive and psychological processes, social and power relationships, and organizational structural inertia. Given the findings from the previous research, organizational learning theories can provide strategic interventions to effectively deal with resistance and to achieve organizational change goals. The learning organization embrace learning activities – unlearning, experimentation, exploration, double-loop learning, and action learning - to develop the adaptability to environmental changes. This chapter suggests that HR/HRD should play a role in building the learning organization and facilitating organizational learning for change as a change agent.
Facing Organizational Change
Authors: Ferrari Filippo
Published: January 2021

This chapter aims to present the obstacles both scholars and practitioners must overcome in facing organizational change. Indeed, too often practitioners lack any rigorous evidence-based background and rely on their previous experience and common sense. At the same time, scholars too often work in a very separated academic world, thus ignoring the actual problems that professionals face in actual firms. Being both a scholar and a practitioner, the author highlights the common challenges likely to be faced by change agents when facilitating organizational change: recognizing the readiness of the involved people to change, their skill mismatch, their previous change history, and the level of cynicism. A fully reflective change agent must consider these factors in designing and implementing an evidence-based organizational change and development (EBOCD) initiative and change agency process if he or she wishes to achieve positive outcomes both from the organizational and the involved people's point of view.

Digital transformation is imperative for gaining and sustaining a firm's competitive advantage. Hence, understanding the dynamics of technology evolution becomes salient for both scholars and practitioners. This chapter aims to provide a complementary perspective to the field of innovation by mapping and visualizing the patterns of digital transformation at the industry level with a particular focus on the role of technology convergence. The authors tracked 20 years of the technology of the U.S. communications industry in order to investigate how digital transformation has shaped the industry technological structure, which are the technological gaps and potential future technology trends. The results show a deep transformation of the industry with many interconnections between technology domains and a high degree of overlap between technology areas.
