Social Media and Social Movements
Authors: Brown Sheldondra J. , Babcock Grace M. , Radu Monica Bixby
Published: August 2020

Because of the increasing importance of the link between social media and social movements, recent research attempts to bridge the gap between media studies and sociological research on social movements. Yet, questions remain unanswered. For example, does social media help facilitate activism that leads to social change? What are the strengths and limitations of social media in creating and maintaining a social movement? This chapter explores these questions and others, paying attention to the #Blacklivesmatter hashtag and social movement, which scholars argue is a power force demanding social change in America. This chapter introduces the concepts of social media and social movements and reviews recent literature examining how social media plays an active role in creating and encouraging social movements. This chapter also considers how sociological theory can provide a better understanding of what social media means for modern social change and concludes with suggestions for future research.

Design and Implementation of a Location-Based Service With Emphasis on a Geographical Database
Authors: Hu Wen-Chen
Published: August 2020

One of the most popular apps is location-based services (LBSs) such as navigation, location-based social networks, and location-based advertisements. However, building an LBS is not a simple task because it involves various subjects and techniques like mobile computing, databases, and security and privacy. One of the major LBS components is geographical databases, which are used to store geographic data like locations and functions (such as restaurants and gas stations). A geographical database is usually hosted on a server because of its huge size and should facilitate geographic data storage, indexing, searching, and matching. This article tries to mitigate the high difficulty of LBS construction by showing the construction step by step with a focus on connecting a mobile device to a server-side geographical database. After reading this article, readers will be able to build an LBS prototype for their research or applications.
Science and the Morality of Weapons Research
Authors: Forge John
Published: August 2020

If it were not for weapons research, there would be no predator drones or smart bombs or improvised explosive devices or assault rifles. The insurgents in the Middle East and elsewhere would have no means to fight, and there would be no wars, large or small. Even more importantly, there would be no vast arsenals of thermonuclear weapons capable of ending much of the sentient life on the planet. The world would then most certainly be a safer place. The main issue for ethics and weapons research centres on the ethical or moral evaluation of the activity: Is it ever morally justified to design the means to kill, harm and destroy, and if so, under precisely what circumstances?
Mobilization
Authors: Williams Idongesit
Published: August 2020

Mobilization is an aspect in every sphere of human endeavor. It is the underlying force enabling the actions evident around us, be it in organizations, our individual lives, society and in governance. There are lots of social theories that provide insights into the dynamics of most actions. These could be actions triggered by individuals or groups. However, social theories that actually explain the main reasons as to why mobilization occurs are either rare or very contextual. In some of these cases, mobilization is treated as a process. But if we think about it, Mobilization is a result of a decision. The decision could either be a conscious or an unconscious decision. There ought to be rational factors that explains why these decisions are made towards mobilization. This is because the choice not to mobilize would also have been triggered by a set of factors. This chapter utilities social movement theories, actor network theory, the logic of collective behavior, and the community-based mobilization networks to attempt to identify the factors that will trigger the decision to mobilize.

Published: August 2020

How to distinguish between fake news or not? How to verify information whether true or not? The goal of this article is to review online fact-checking studies on fake news. The core of this matter is how to progress fact-checking on misleading information and vague knowledge. This procedure is crucially managed by manually or some computational mechanisms. The burden of proof should be evaluated truthiness by scientific ways included objectiveness and falsifiability. It never accepts neither solipsism nor agitating manners. In addition, it should take carefully to extract the most importance from the truth whether manually or mechanically, and it also reconsiders those backgrounds. For sound democracy, mediated knowledge brings the facts for citizens, and it should encourage them to ponder their directions of governances in nation. Using ICT, it should properly facilitate fundamental educations for them.

Authors: Erener Arzu , Sarp Gülcan , Düzgün Şebnem
Published: August 2020

In Turkey, landslides are the second most common natural disasters that cause damages in Turkey that follow the earthquakes. Thus, landslide risk assessment is of crucial importance in this area. Therefore in this study a quantitative approach for mapping landslide risk is developed for property and life at local scale. The approach is first based on the identification of existing elements at risk in the area by the developed algorithm. Then the vulnerability approach focuses on determination of quantitative vulnerability values for each element at risk by considering temporal and spatial impacts by adopting a “damage probability matrix“ approach. The loss estimation was combined with the hazard values which are based on former work done in Bartın Kumluca area where a detailed study of landslide occurrence and hazard in the recent past (last 30 years) was carried out. The final result risk maps for property ($/pixel/year) and life (life/pixel/year) shows all losses per pixel annually for each element at risk in Hepler village.

Published: August 2020

There is a skewed perception of the differences in access to and use of ICTs in modern society, especially in technology less-advanced nations. While there are various schools of thought on this topical issue, less is evident to establish that males and females have equal access to and use of information and communication technologies. Given the role of ICTs for development and the significance of gender equality to economic advancement as seen in the sustainable development goals, understanding gendered access to and use of ICTs can help develop interventions that help close the gender gap in access to and use of ICTs in order to help women leverage technology for socio-economic inclusion. The study, therefore, attempted to understand the presence or absence of gender differences in access to and use of ICTs and identify the causes in order to guide the development of interventions aimed at closing these gaps.
Modernizing the Academic Library
Authors: Joe Jennifer Ashley Wright
Published: August 2020

The digital age has been presented as a stark contrast to everything that libraries have had to deal with prior to now. While it is true that academic libraries have had to change to stay relevant in the digital age, the changes are not as severe as was once thought. When libraries embrace a few simple changes and start thinking outside the box when it comes to their employees, their resources, and their mission statements, they begin to meet the challenges that the digital age presents, and will continue to thrive in the new world presented by electronic materials, while remaining true to their spirit of information exchange and knowledge sharing.

Authors: Sen Devjani , Ahmed Rukhsana
Published: August 2020

With a growing number of health and wellness applications (apps), there is a need to explore exactly what third parties can legally do with personal data. Following a review of the online privacy policies of a select set of mobile health and fitness apps, this chapter assessed the privacy policies of four popular health and fitness apps, using a checklist that comprised five privacy risk categories. Privacy risks, were based on two questions: a) is important information missing to make informed decisions about the use of personal data? and b) is information being shared that might compromise the end-user's right to privacy of that information? The online privacy policies of each selected app was further examined to identify important privacy risks. From this, a separate checklist was completed and compared to reach an agreement of the presence or absence of each privacy risk category. This chapter concludes with a set of recommendations when designing privacy policies for the sharing of personal information collected from health and fitness apps.
Islamic Medical Ethics in Brunei Darussalam Hospitals
Authors: Fauzi Syazana
Published: August 2020

In Islam, issues and concerns that arise in Muslim societies are addressed and often resolved by issuing fatāwā, or religious rulings, derived from the ‘ulamā's reasonings that are based on the Qur'ān and the Sunnah. In Brunei Darussalam, its State Mufti provides religious verdicts on various issues, including healthcare. Thus, this chapter seeks to analyse whether Brunei Darussalam's health professionals handle medical ethical cases in a manner that is congruent to the State Mufti's fatāwā. There are many issues pertaining to ethics in medical healthcare, however, only three contentious ones will be discussed: euthanasia, organ transplantation, and abortion. A semi-structured e-mail interview was sent to several hospital nurses under relevant departments. The findings demonstrate a certain degree of congruity, with the exception of abortion cases. The State Mufti declared that abortion in rape cases is not sinful, but legally, it would still be considered as a crime, as the Brunei law states that abortion is permissible only if the pregnancy is detrimental to the mother's health.

Published: August 2020

This article presents research and development on innovative photoactive admixtures for concrete and cement-based plasters for the finishing of concrete surfaces. The goal is to provide the resulting surfaces of these newly developed materials with a self-cleaning ability stemming from photocatalytic reaction during exposure to UV radiation. This research and development is currently underway as part of a project supported by the Czech Ministry of Industry and Trade, in the TRIO programme; and in cooperation with BETOSAN s.r.o., the Technical University of Liberec, the Institute of Inorganic chemistry of the Czech Academy of Sciences and the J. Heyrovsky Institute of Physical Chemistry of the Czech Academy of Sciences. The first type of material under development is a photocatalytically active admixture in powder form, allowing the preparation of concrete surfaces with photocatalytic properties. The second type of material under development is a photocatalytically active cement-based plaster, intended primarily for application to a concrete substrate. The preparation of two or more final versions is to be expected for both types of materials. In the case of the plaster this includes the preparation of two colour variants, specifically white and grey. For the powdered cement admixture we expect the preparation of various types based on their application. This could mean different types of admixtures mixed throughout the entire volume of the concrete or only in the surface layer of the concrete. We envisage exterior applications on the self-cleaning outer shell of buildings, as well as treatment of the surface layer of various structures such as bridges, noise barriers, traffic barriers and tunnels. The materials created could also be used in interiors under specific conditions, with anticipated uses in the health care and food processing industries.
Experimental Investigation of Bond between GFRP Reinforcement and Concrete
Authors: Holly Ivan
Published: August 2020

The reinforcing steel embedded in concrete is generally protected against corrosion by the high alkalinity (pH = 12.5 to 13.5) of the concrete pore solution. The structural degradation of concrete structures due to reinforcement’s corrosion has an impact on the safety, serviceability and durability of the structure. The corrosion of reinforcements in the construction of a transport infrastructure (especially bridges), parking areas, etc., is primarily initiated by chlorides from de-icing salts. Glass fiber reinforcement polymer (GFRP) bars are suitable alternatives to steel bars in reinforced concrete applications. The bond between concrete and reinforcement is one of the basic requirements for the composite action of both materials. The transfer of forces between the steel reinforcement and the concrete is provided by the following mechanisms: adhesion, friction and mechanical interlocking. The bond between GFRP reinforcement and concrete is different and it is ensured by friction and mechanical interlocking of the rebar surface. The chemical bond does not originate between GFRP reinforcement and the surrounding concrete, so adhesion does not contribute to transfer of the bond forces. Some few test methods are used to determine the bond between GFRP reinforcement and concrete. The pull-out tests were used to determine the bond behavior between GFRP rebars and concrete. This paper describes the preparation, process, results and evaluation of the pull-out tests.

Experimental and Numerical Evaluation of UHPFRC Slabs Subjected to Contact and Close-In Explosion
Authors: Janota Ondřej , Foglar Marek
Published: August 2020

This paper presents achievements in the field of the numerical simulation of the fibrere reinforced concrete (FRC) and ultra-high performance fibre reinforced concrete (UHPFRC). The numerical simulations were performed to verify results of two experimental programmes focused on the blast resistance of FRC and UHPFRC. The response of the FRC and UHPFRC slabs to the contact and near-field blast was studied in these two experiments. As the detail behaviour of specimens could not be observed because of the blast load, the numerical models were prepared. The accuracy of the numerical models was evaluated based on the comparison of numerical and experimental results. Different approaches for blast simulation were tested and compared. The results indicate that the various phenomena (e.g. overpressure propagation, stress cumulation, crack propagation and damage extend) can be successfully simulated. However, the comparison of the soffit velocity, measured with the PDV unit and numerical model showed shortcomings of the numerical model. These numerical model inaccuracies are discussed and their reasons presented.

Authors: Vaitová Michaela , Jendele Libor , Červenka Jan
Published: August 2020

This paper presents the possibility to utilize the 3D printing technology in civil engineering field specifically for concrete structures. Since this technology is booming last years and spreads in different fields of industry, the tools to analyse structures in such a way is important. Many research groups worldwide try to develop cement-based material suitable for 3D printing so that it might be used for civil engineering structures. Moreover, this technology brings necessity to check the safety of the structure at early ages of concrete. Therefore, the modelling and simulation of the digitally printed concrete structure would be of great help for such effort. The software tool that enables simulation of digitally printed concrete structure using a nonlinear FEM analysis is presented. ATENA is well established tool for such analyses of civil engineering structures made of concrete. The new module for digital printing simulation is developed as an additional feature of ATENA software. The 3D extrusion technology is supported. The paper describes the whole procedure how to model and analyse such structures and stress out all the differences compared to analyses of structures produced by traditional manner. The structure itself is modelled as usual in FE software, whereby based on velocity of printing head the time of printing, i.e. production of each element is calculated. It is later used to activate the elements during analysis and it also influence the material behaviour, such as shrinkage, strength etc.

Authors: Kocáb Dalibor , Žítt Petr , Hüblová Sabina
Published: August 2020

The paper discusses means of testing the freeze-thaw resistance of concrete, which is part of an existing structure. Practically all standards and regulations dealing with freeze-thaw resistance describe tests that require cast prism-shaped specimens. This can make determining the freeze-thaw resistance of a concrete part of a structure rather difficult. The paper discusses the problem in detail, proposes solutions, and presents a real-world example of determining the freeze-thaw resistance of bridge abutments.

Authors: Kostiha Vojtech , Girgle Frantisek , Januš Ondřej , Švaříčková Ivana , Stepanek Petr
Published: August 2020

This paper is focused on the design of concrete structures reinforced with modern composite material – Fibre Reinforced Polymer (FRP) reinforcement. It presents actual results from the testing of FRP rods under a simultaneous tensile and shear loading. The results were experimentally obtained on specimens of Glass Fibre Reinforced Polymer (GFRP) reinforcement. The text also points out that the widely used fib Bulletin no. 40 technical report does not provide sufficiently reliable formulas and may overestimate the load-bearing capacity of the element. Therefore, the conclusions formulated are primarily concerned with their practical use in the design of this modern material.

Authors: Jeong Go Woon , Shin Wonkyo , Lee Dong Ock , Seo Sang-Soo , Kang Sokbom , Park Sang-Yoon , Lim Myong Cheol
Published: August 2020

PurposeThe BRCA1 or BRCA2 gene is transmitted in an autosomal dominant fashion, and genetic testing of first-degree relatives of patients with family-specific mutation (FSM) is recommended. This study examined factors affecting the uptake of FSM testing among relatives of patients with peritoneal, ovarian, or fallopian tube (POFT) cancer with confirmed BRCA1 or BRCA2 germline mutation.Materials and MethodsData from medical charts of 392 eligible patients and their relatives who had undergone outpatient genetic counseling/testing were retrospectively reviewed. Clinical factors were compared between family members who had and had not undergone genetic counseling/testing.ResultsThe uptake of FSM testing was 30.5% (129/423) among first-degree living relatives and 53.5% (69/129) within the overall family unit. The average time from genetic testing of the proband to the first FSM test within a family was 168 days (range, 23 to 681 days). Having a living father (33.8% vs. 13.3%, p=0.007) and daughter (79.4% vs. 60.3%, p=0.019) increased the uptake of FSM testing. FSM testing was more likely among female than among male relatives of cancer patients (40.9% vs. 17.6%, p < 0.001).ConclusionApproximately one-third of first-degree relatives of patients with a POFT cancer with BRCA1 or BRCA2 mutation underwent FSM testing. Having a living father or daughter was a factor affecting the uptake of FSM testing, which was higher among female than among male relatives of the proband. This discrepancy might be due to a misconception that the BRCA gene is associated with women rather than with men.

Authors: B Sangeeth Kumar, Pyasa Dileep and A Satyanarayana
Published: August 2020

In this paper we are design a circuit based on data selector and distributor networks in which we will not
realize the circuit based upon the expressions but off course the circuit which have designed will have
internally some expression. In the recent trends the need for low power and less on-chip area is on high note
for the portable devices. In this project we want to focus on the design constraints of VLSI. Innovative design
of 8-Bit GDI based Comparator will be proposed and implemented. Optimization depends on selection of GDI
Cell as well as selection of primary inputs to the terminals of GDI cell. 8-Bit GDI based Comparator will be
designed and simulated using Tanner EDATool. Comparator has three main outputs where it can compare the
weight of two words and generates three functions. GDI has the advantage of low power consumption
because the total number of logic devices needed willbe less and it can also operate with high speed due to
affective realization of logic using minimal hardware. Comparator circuits is designed using tanner tools and
also observe the simulation results in H-SPICE attaining low power and less delay.
Three Phase Eleven Level Modular Multilevel Inverter with PD-PWM for Grid Connected System
Authors: Dr. Sujatha Balaraman, P Yogini
Published: August 2020

The prominence of Modular Multilevel Inverters (MMI) is rising owing their merits of simple mechanical
construction and good voltage sharing for semiconductor devices. Mostly Multilevel Inverters use more than
one source; however, the effective use of all the sources at all levels is rare. Conventional Multilevel Inverters
will diminish the energy efficiency of the conversion system. When compared to conventional multilevel
inverter, Modular Multilevel Inverter with a high numbers of voltage levels seem to be the most suitable
because of the use of an isolated dc source. This paper explores a three-phase eleven level modular multilevel
inverter with phase disposition pulse width modulation technique (PD-PWM) that can extract power from all
the sources at all the levels. Besides, this paper develops a synchronous d-q reference frame controller to
control the current of 11kV. When compared with Reduced Switch Count based Multilevel Inverter
Series/Parallel switching topologies, the Modular Multilevel Inverter provides better Total Harmonic
Distortion (THD) of output voltage and utilization factor.

in a multi-area power system. The CDM controller has been designed in order to reduce effect of the
vagueness as a result of governor and turbine parameters variation and load disturbance. Single-area and
two-area power system frequency dynamic paradigms are modelled, as well as the physical constraints of
the governors and turbines are considered. MATLAB/Simulink simulations for a single area power system
and two area power system are performed to validate the effectiveness of the proposed scheme. From the
simulation results it is confirmed that the proposed CDM technique, gives enhanced performance under load
disturbances and constraints in the parameters. Performance comparison is made between the proposed
CDM controller and an integral controller which affirms the upside of the proposed CDM method.
Implementation of PSO MPPT Technique for Wind Energy Conversion Systems
Authors: R Ramesh, M Sravani Durga
Published: August 2020

One major advantage of renewable energy is that it is sustainable and will never run out. They provide
clean energy because they are non-pollutant and non-contributor to greenhouse effects and global warming.
Renewable energy facilities generally require less maintenance than traditional generators. Their fuel being
derived from natural and available resources reduces the costs of operation. The proposed PSO algorithm
uses the dc current as the perturbing variable. The algorithm detects sudden wind speed changes indirectly
through the dc-link voltage slope. The voltage slope is also used to enhance the tracking speed of the
algorithm and to prevent the generator from stalling under rapid wind speed slow down conditions. The
proposed method uses two modes of operation: A PSO mode with adaptive step size under slow wind speed
fluctuation conditions, and a prediction mode employed under fast wind speed change conditions. The
dc-link capacitor voltage slope reflects the acceleration information of the generator, which is then used to
predict the next step size and direction of the current command.
