AbstractThe understanding of the algebraic variable has been widely discussed, with different populations and through different tools. However, there are few studies investigating its approach through the use of computational resources. In this sense, this work assesses the contributions of the Scratch programming language in the meaningful learning of the algebraic equations of the 1st degree. The case study was carried out with students regularly enrolled in the 8th grade of a state school in Lages - SC. The proposed activities, developed in mathematics classes, corresponded to 10 meetings in a total of 16 hours. For data collection, a qualitative investigation was adopted with the application of tests before and after the interventions, on previous knowledge related to the algebraic equations of the 1st degree and programming logic and acquired during the development of the activities. The Scratch software was presented as an aid tool in solving algebraic problems and students were encouraged to build their own projects using the programming language. It was observed that, in this scenario, Scratch helps to solve the difficulties of the students in relation to the content of Algebraic Equations of the 1st degree, making the learning of the concept of algebraic variable more significant.

INTRODUCTION: Electric scooters have become popular in Iceland. The aim of the current study was to gather data on the incidence, causes, and severity of injuries due to the use of electric scooters in the Reykjavik area during the summer of 2020. MATERIAL AND METHODS: Individuals presenting to the Emergency Department (ED) at Landspitali between June 1 and August 31 were asked about the location and cause of accident, use of protective equipment, and use of recreational drugs and alcohol. Diagnosis and treatment data was gathered from hospital records. RESULTS: During the study period, 149 individuals presented with electric scooter injuries, on average 1.6/day. Patients‘ age ranged between 8 and 77 years, and 45% were younger than 18 years of age. In 60% of cases the cause of accident was that the patient was riding too fast, lost balance, or uneven road surface. Seventy-nine percent of children reported using a helmet, compared to only 17% of adults. No children reported having been under the influence of alcohol or recreational drugs at the time of the accident, compared to 40% of adults who reported that they were intoxicated. Fractures were diagnosed in 38% of patients, 6% needed hospital admission, but no patient suffered serious injury. CONCLUSION: During the summer of 2020, one to two individuals were injured daily in the Reykjavík capital area while using electic scooters, but no serious injuries occurred. Preventive measures to decrease injury rate from the use of electric scooters should focus on infrastructure, encourage helmet use, and education on the risk of injury associated with operating electric scooters while intoxicated.

Cardiac lipomas are very rare benign tumors of the heart. They are usually asymptomatic and are often an incidental finding on cardiac imaging. This case report involves an 82-year-old female with a history of diabetes admitted because of poor glycemic control. An echocardiogram requested because of arrhythmias and heart failure revealed a tumor in the right atrium. Computed tomographic and ultrasound appearances were consistent with a lipoma and demonstrated a large mass in the right atrium, causing a significant stenosis of the superior vena cava but no clinical symptoms or signs of superior vena cava syndrome.

Authors: Pham Thi Kim Anh
Published: May 2021

Students’ competence development teaching has been discussed and researched quite a lot since the 90s of the twentieth century, especially after the Resolution No. 29-NQ\T. of the Party Central Committee (2013) about basic and comprehensive innovation in education and training in Vietnam. However, not all general teachers have correctly and explicitly understood competence development teaching. To help teachers understand this issue, the article focuses on clarifying: What is competence development teaching?, What are the characteristics and meanings ?; What is new and different from competence development teaching with traditional teaching; What are the typical signs of competence development teaching?
INFLUENCE OF RELAXATION TIMES ON HEAT TRANSFER IN HUMAN HEAD EXPOSED TO MICROWAVE FREQUENCIES
Authors: KAUR Jagbir , KHAN Suyeb
Published: May 2021

The electromagnetic energy carried by microwaves interacts with human head and produces thermal changes within the head. Conventionally, Pennes’ bioheat transfer equation (BTE) is employed to investigate the thermal changes in biological tissues. Pennes’ equation assumes infinite speed of propagation of heat transfer, however, heterogeneous structures such as biological tissues exhibit relaxation times, which is the time required for accumulation of enough energy to transfer it to the nearest element. In present study, we utilized thermal wave model of bioheat transfer (TWMBT) which incorporates relaxation times to numerically predict temperature changes in six layers human head. Finite element based numerical simulation package COMSOL Multiphysics is employed for the thermal analysis. Numerical scheme comprises coupling of solution of Maxwell's equation of wave propagation within tissue to TWMBT. Temperatures estimated with various values of relaxation time are compared with that by Pennes’ equation. The results show that the transient temperature within human head estimated with relaxation time 10 s, 20 s, and 30 s can be up to 36%, 54%, and 66% lower than predicted by Pennes’ BTE respectively. At longer microwave exposure the influence of relaxation times becomes insignificant and the steady state temperatures predicted by TWMBT and Pennes’ BTE are identical. The findings suggest that inclusion of relaxation times in thermal analysis is of significant importance if the exposure duration is short. The effect of parameters such as microwave power and user age on the temperatures projected with different relaxation times is also investigated.
CFD MODELING OF SLURRY PIPELINE AT DIFFERENT PRANDTL NUMBERS
Authors: PARKASH Om , KUMAR Arvind , SİKARWAR Basant
Published: May 2021

The present work shows the slurry flow characteristics of glass beads having density 2470 kg/m3 at different Prandtl number through a horizontal pipeline. The simulation is conducted by Eulerian two-phase model using RNG k-ε turbulence closure in available commercial software ANSYS FLUENT. The transportation of solid particulates has the settling behaviour in the slurry pipeline and that leads to the sedimentation and blockage of the pipeline resulting more power and pressure drop in the pipeline. Therefore, it is important to know the transport capability of the solid particulates at different Prandtl fluids to minimise the pressure loss. The fluid properties at four Prandtl numbers i.e. 1.34, 2.14, 3.42 and 5.83 is used to carry the solid concentration ranges from 30-50 % (by volume) at mean flow-velocity ranging from 3 to 5 ms-1 . The obtained computational results are validated with the published data in the literature. The results show that the pressure-drop rises with escalation in flow velocity and solid concentration at all Prandtl number. It is found that the suspension stability enhancement is considerable for lower range of Prandtl number and decreases for higher range of Prandtl number. Finally, glass beads concentration contours, velocity contours, concentration profile, velocity profiles and pressure drop are predicted to understand the slurry flow for chosen Prandtl numbers.

“No Difference Between African American,Immigrant, or White Children! They Are All the Same.”: Working Toward Developing Teachers’ Raciolinguistic Attitudes Towards ELs
Authors: Song Kim , Kim Sujin , Preston Lauren Rea
Published: May 2021

This study explored Midwestern US teachers’ raciolinguistic attitudes toward English learners. Two research questions guided the study: “How did teachers perceive racism and linguicism” and “How did a professional training influence teachers’ awareness of them?” Critical race theory was used to examine how racism evolved into racialized linguicism. Data analysis demonstrated that teachers tended to conflate the experiences of African American students and English learners, even though they are linguistically and culturally distinct. They also tended to understand the racism and linguicism encountered by the two groups in Black/White and Standard-English/Nonstandard-English binaries. Implications consider the future direction of TESOL teacher education.
The Elephant in the Classroom: Using YouTube Comments to Address the Essential but Unacknowledged Topic of Race
Authors: Riley Jacqueline , Slay Laura E. , Revelle Carol
Published: May 2021

Drawing on critical race media theory, this praxis article describes how instructors can effectively introduce critical race literacy theory in a teacher education class using online videos. Ultimately, this study helps us to better understand how viewing YouTube videos and responding critically to YouTube user comments can help preservice teachers acknowledge and challenge their pre-existing beliefs related to teachers and students of color in a teacher education writing course. Data analysis reveals that preservice teachers’ idealism for compassionate teaching is embedded in a superficial understanding of sociocultural differences and lacks an understanding of how race affects student learning.
From Google Searches to Russian Disinformation: Adolescent Critical Race Digital Literacy Needs and Skills
Authors: Tynes Brendesha , Stewart Ashley , Hamilton Matthew , Willis Henry
Published: May 2021

This study uses a Critical Race Digital Literacy framework to examine Black and Latinx adolescents’ ability to critically evaluate race-related materials online. Participants completed four tasks that required them to engage with a range of race-related material, from search results to social media content. Findings indicate that the majority of participants demonstrated an “emerging” or “mastery” level understanding of search results and determining the trustworthiness of websites. Participants found evaluating the credibility of Twitter content as well as evaluating a Russian disinformation campaign’s Facebook profile targeting African Americans considerably more challenging. In addition, though 34% recognized a video screenshot arguing that building a wall at the southern border is humane as racist, participants had difficulty combining this knowledge with an understanding of online propaganda. Few participants reached mastery on this task, and others that required them to evaluate social media content and recognize disinformation. As more online content and media are explicitly related to race or references specific racial groups, these findings highlight the need for more interventions to enhance competencies around critically evaluating race-related materials online.

Authors: Qureshi Ahmed Ali , Naqvi Sayyed M. Mehdi Raza
Published: May 2021

Purpose of the study: The purpose of the study was twofold, first to find the antecedents and consequences of employee voice using the theory of planned behaviour, and second to develop, introduce and validate the construct of employee reticence (employee-silence attitude) and its scale.

Methodology: Mixed-Method Research using interviews, and questionnaire was the methodology of the study. IBM SPSS 20.0 and SmartPLS 2.0 software were used for data analysis to test and confirm face validity, content validity, reliability, item reliability, convergent validity, discriminant validity, nomological validity.

Main Findings: Employee reticence is a valid employee attitude. The employee silence behaviour is supported by the theory of planned behaviour. It was found that the Theory of planned behaviour applies to the situations of employee silence. The scale of employee reticence developed, as the result of this study, is valid and ready to be used by researchers, organizational behaviourists, psychologists, and HR experts.

Applications of this study: The study is applicable for change intervention programs in organizations by organizational behaviourists. The researchers can use it to explore and develop organizational and team-level attitudes of silence. Its scale is a useful tool, largely for recruiters for ensuring PO fit. It is usable to researchers for further exploration and using it as in organizational research including but not limited to Employee silence, knowledge management, and stress. Psychologists can take the lead from the concept of ER to develop similar constructs for their field for analysing their patients of stress etc. from this perspective.

Novelty/Originality of this study: The study is novel and original as the construct of employee reticence has been developed, introduced, and validated (employee-silence attitude). Further, the scale of the new construction has been constructed and validated, using standard methods.

Aim: This research aims to define equities determinants in maternal and child care in Punjab, a Pakistan province. The study focuses on the impact on Reproductive/ Maternal/ Newborn/ Child Adolescent Health (RMNCAH), introduced in 2016 through the Investment Case (IC) approach.

Methodology: A complex-sample-analysis modified the weight of the sample. Weighted disaggregated data were produced by cross-tableting with Confidence Interval (CI). A DiD analysis was performed based on a linear model of regression. Finally, the effect of the involvement was calculated by multivariate linear regression.

Principal Findings: The results show that changes had been measured in both the involvement and reference areas in involvement and no significant associations in the variables. Changes in involvement and contrast areas were similar. Also, there was no substantial improvement in aggregate outcomes from the multivariable regression analysis. In most developing countries, the IC approach is successful. Following the IC's introduction, some MNCH indicators such as ANC and the delivery of expert delivery of assistant birth showed improvements in involvement and contrast districts.

Applications of this study: The research will provide a proper guideline for the policymaker to design a need-based policy for equitable admission to child health care and maternal facilities

Novelty/Originality of this study: This study first analyzed the influence of investment- case in the RMNCAH program in Punjab.
New Discourses on Energy Transition as an Opportunity for Reconciliation? Analyzing Indigenous and Non-Indigenous Communications in Media and Policy Documents
Authors: Mang-Benza Carelle , Baxter Jamie , Smith Fullerton Romayne
Published: May 2021

This article examines energy issues articulated by Indigenous and non-Indigenous people in Canada and analyzes the energy transition as a locus of reconciliation therein. Using content and discourse analysis of policy documents, white papers, and news media articles, we draw attention to reconciliation and energy discourses before and after 2015, the year that marked the release of the Truth and Reconciliation Commission of Canada (TRC) report and the Paris Agreement on climate change. We find a three-fold expansion of those discourses, which encompass issues of inclusion and exclusion, dependency, and autonomy, as well as colonial representations of Indigenous people, after 2015. We also find that non-Indigenous voices are more prominent in those conversations. We suggest that the prospects of mutual benefits could turn the energy transition into an opportunity to bring together Indigenous and non-Indigenous people in Canada.
Substituição parcial de agregados pétreos naturais por agregados reciclados de revestimento cerâmico em uma mistura para aplicação em camada de base de pavimento
Authors: Steiner Luiz Renato , Bernardo Danieli
Published: May 2021

Devido à geração desenfreada de resíduos, e consequente saturação dos locais específicos de descarte, buscam-se cada vez mais alternativas que visam dar novas utilizações a estes materiais. Em pavimentação, a utilização de resíduos contribui também para a diminuição no uso de recursos naturais, promovendo uma desaceleração no processo de exploração. Neste contexto, este estudo tem como objetivo principal avaliar a substituição parcial dos agregados pétreos naturais por agregados reciclados de revestimento cerâmico (ARRC) na elaboração de uma mistura (BGS+ARRC) para possível utilização como camada de base de pavimento. Nesta mistura (BGS+ARRC), 42,32% dos agregados pétreos naturais foram substituídos pelo ARRC. Os ensaios de granulometria com os agregados possibilitaram o enquadramento da mistura (BGS+ARRC) na Faixa granulométrica “A” do DNIT. Para fins de comparação, foram elaboradas também misturas de Brita Graduada Simples - BGS (Referência). Os ensaios físicos demonstraram que o ARRC utilizado apresenta maior porosidade quando comparado ao agregado pétreo natural. E isto é uma característica própria dos revestimentos cerâmicos, demonstrada por sua absorção que, dependendo do tipo de revestimento, pode apresentar teores entre 0 à maiores que 20%. Esta característica do ARRC pôde ser observada também nos resultados obtidos nos ensaios de abrasão “Los Angeles” e degradação do agregado após a compactação, onde o ARRC apresentou maior desgaste e quebras que os agregados pétreos naturais. No ensaio de índice de fôrma do ARRC, verificou-se a forma cúbica predominante e pouca quantidade de partículas lamelares. Os ensaios mecânicos demonstraram que a mistura (BGS+ARRC) demanda maior quantidade de água para atingir sua máxima densificação, porém esta apresenta valores superiores de ISC/CBR em comparação com a BGS (Referência), visto que este é um parâmetro importante para avaliar sua utilização em camadas de pavimento. Por fim, após a verificação dos resultados dos ensaios realizados com a mistura (BGS+ARRC) em estudo, foi possível afirmar que esta alcançou os objetivos esperados, possuindo características que habilitam seu uso em camada de base de pavimento.

The results of studies carried out in the Pravdinsky nursery of the Pushkin Forestry Technical Colledge in the Moscow Region and in the laboratory of the department «Forest cultures, selection and dendrology» at the ВMSTU (Mytishchi branch) since May 2015 untill September 2019 are presented. The results of the study confirmed the significant advantage of experimental indicators over the control. Thus, the treatment of seeds and two-year-old seedlings of Scots pine with a low-frequency electromagnetic field using the POSEP technology, in general had a positive effect not only on their survival rate and biometric parameters, but also on their anatomical structure. Based on the results of the studies, it can be ststed that the POSEP technology is an effective method of physical impact on the survival rate and growth increase of Scots pine seedlings.

The allelotoxicity influence of 12 samples of Great Russian Plain soils on the seed germination of different cultivars of spring wheat was assessed. Based on the obtained data it is concluded that the effect of biologically active substances (BAS) on seed germination is due, on the one hand, to the content of these substances in the soils, and on the other hand, to the various content in seeds of BAS required for their development. The supposition about the existence of a common mechanism to protect the seed from the negative influence of soil allelotoxins is made.

Valuation of Shares and their Fair Value of the Companies Listed on the Wig-Ukraine Quoted on the Warsaw Stock Exchange in Poland within 2011-2015
Authors: Parvi Rafal
Published: May 2021

This paper examines share price of the companies listed on the WIG-Ukraine and their fair value between 2011-2015. Data from Q4 2013 to Q2 2014 was collected from the Stooq.pl (Polish portal of shares). Two hypotheses are tested: (1) value of the shares based on the market price; (2) value of the shares as the fair value of shares. In this paper, the WIG-UKRAINA stock exchange sector companies, which oppose a bad economic situation in Ukraine caused by military actions on its territory, were analysed. These companies were subject to detailed research in order to demonstrate that they have the potential to act on the free market and that they do not lose their financial liquidity. In addition, their fair value was shown, because the current economic and market situation in Ukraine completely deprived it of this value.

Published: May 2021

Background: A laboratory incubation study was carried out to study the influence of long term manuring and fertilization on soil organic matter (SOM) quality by means of C mineralization in terrace soil of Bangladesh. Methods: Soil samples were collected in 2016 from a highly weathered terrace soil with rice-wheat cropping pattern at Bangabandhu Sheikh Mujibur Rahman Agricultural University experimental farm having five OM (control, cow dung, green manure, rice straw and compost) treatments combined with three mineral N fertilizer (control, 155 kg ha-1, 220 kg ha-1) levels. A model was used to explain detected C mineralization in soil known as parallel-first and zero order kinetic model. Result: Long term (28 years) application of mineral fertilizers and manure resulted that all the estimated parameters were not significantly influenced by either manure application or N fertilization except C mineralization rate was constant for resistant carbon pool (ks). The ks value was significantly influenced by manure application. Cumulative annual C mineralization evolved from SOM under field conditions were estimated between 6.21 to 9.31% of total soil organic carbon. The annual carbon mineralization was found to be significantly influenced by different exogenous organic matter application but not with N fertilization. There was a significant difference in annual C mineralization between green manure, cow dung and compost. However, the annual C mineralization was statistically similar between control and green manure treated soil. This result indicates that more stable organic matter was formed in compost treated soil which is less prone to decomposition if present crop management has been changed.
Potential, Challenges and Strategies Involved in Gene Introgression from Wild Relatives of Vegetable Crops: A Review
Authors: Chauhan Aanchal , Sharma Deepa , Banyal Sanjeev Kumar , . Madhvi , . Divya
Published: May 2021

Wide hybridization is an important plant breeding method as it helps in broadening the gene pool of a crop when the desired variation is not sufficient or absent within the same gene pool. Wild genetic resources are the potential source of desirable genes for various characters of crop plants. It plays a significant role in transferring traits of interest like disease and insect resistance, improved quality, earliness, dwarfness, increased yield, abiotic stress tolerance and manipulation in mode of reproduction etc. in crop plants. It has been instrumental in transferring disease resistance from wild species into many vegetable crops. For example, resistance to late blight, leaf roll and potato virus X, yellow vein mosaic virus and powdery mildew in okra, bacterial wilt, tomato leaf curl virus, early and late blight in tomato has been transferred from wild species into cultivated species. Wild species has been used to improve the quality traits of some crops like carotenoid content in carrot and tomato, starch content in potato etc. Sometimes distant hybridization leads to creation of entirely new crop species. Chromosome elimination technique followed by wide hybridization has been successfully used in the production of double haploids in some crops. However there are some lacunae in wide hybridization such as cross incompatibility, hybrid inviability, hybrid sterility and hybrid breakdown. Some special techniques viz. ploidy manipulation, pistil manipulation, growth regulators treatments, bridge crossing, grafting and embryo rescue have to be adopted to make distant hybridization successful in such cases.

Authors:   North West University, DLAMINI Nontobeko , CHOGA Ireen ,   North West University
Published: May 2021

The study investigates the determinants of energy intensity in the South African manufacturing industry. The objectives are to analyse trends, to determine the drivers of manufacturing energy intensity and make policy recommendations. The study investigates the effects of manufacturing value added, foreign direct investments, energy prices and trade openness on manufacturing energy intensity. The study employs the Vector Error Correction Model on time series data for the period of 1980 to 2017. The findings of the study depict that manufacturing value added, foreign direct investment and energy prices are the most important determinants in explaining manufacturing energy intensity over the reviewed period. Manufacturing value added is found to be statistically significant both in the short and long run. Foreign direct investment is found to be statistically significant in the long run whereas, energy price is significant in the short run. In light of this, the study makes policy recommendations. With regards to total manufacturing value added, the study recommends that the industry be closely monitored. Government should subsidize energy efficient machinery and equipment and the use of old outdated technology should be banned. With regards to foreign direct investment, the study recommends that the FDI policy be reviewed such that it attracts foreign investors. The recommendation regarding energy prices is that government should encourage energy price reform and use subsidies to encourage energy saving enterprises.

Authors: Ibrahim Umar Abbas , Isiaka AbdulQudus
Published: May 2021

This study examined the long-run effect of financial leverage on firm value with evidence from a sample of 62 firms quoted on the Nigerian Stock Exchange, over the five-year period between 2014-2018. The level of financial leverage as measured by the Debt-Equity ratio while firm value was represented by Tobin’s Q Market-Book Value Ratio. The study contributes to the literature by appraising the dynamic dimensions of the causal relationship between firm value and financial leverage, an investigation that has remained elusive in indigenous studies. The study determined the degree of long-term causality by employing an auto-regressive model estimated by the Generalized Method of Moments (GMM) technique. The regression results show that financial leverage has a significant positive effect on the firm value both in the short and long run, while the result of the correlation analysis carried out reveals that there is a significantly positive and strong linear relationship between the time series of firm value and its lagged version implying that firm value does not demonstrate traits of Mean reversion. The Management of these companies was advised to optimize firm value by undertaking quality projects and relying more on debts for funding.

In this research, we tried the check the impact of online learning upon the students of Lebanese French University Erbil, Kurdistan region Iraq. The Objectives of the study are multi-folded. Firstly, to evaluate the influence of online learning upon the performance of students and secondly, to test the motivation of online learning towards the students. For this purpose, a detailed questionnaire was developed in order to get the response of the students. The questionnaire was built up and distributed to almost eighty respondents in which we got back a perfect response in complete shape only fifty.  Graph analysis has been used in order to present the response of the respondent. Mix response was recorded in which slightly negative response was in high portion. Furthermore, results showed that 60 % of respondents answered they are not happy with the online learning process and they want to have a traditional learning process that is on campus. Similarly, in each question, an extraordinary negative response toward online learning is recorded such as 76 % respondents said that they are not satisfied with this implementation of online learning. Also, they are facing hurdles and 58 % of people showed their response one of the big challenges toward online learning is a poor internet connection. 60% claimed that the instructor is not helping them to understand this whole process as a tool of online learning. The possible reason that was claimed from respondents are following: (i)This online process is first time they are interacting with,(ii) Lack of training of such online tools for the online learning process, (iii) once any student is facing trouble while this online process less support is available from the department and technical staff of the university

Published: May 2021

The delivery system for Base Transceiver System (BTS) to strengthen the telecommunication network throughout Indonesia maritime country is needed to speed up the process due to uneven distribution of sufficient telecommunications infrastructure. PT. Gunadhya Rajawali Logistik (GRL) is a third-party logistics company that focuses on transportation and warehouse management and delivery for telecommunication equipment tools. Unfortunately, in delivering BTS installation part throughout Indonesia, PT. GRL received several warning letters and had to pay a penalty from one of customers, for being late in reporting the delivery proof. This study aims to analyze the root causes of late submission of Soft Copy of Proof of Delivery (SCPOD) to avoid penalty given by the customer and determine suitable solutions to improve the process. The approach used in this study is lean six sigma with the help of Define, Measure, Analyze, Improve, and Control (DMAIC) roadmap. According to the interview with the employees related, the root causes of late submission of SCPOD are irresponsible drivers, indiscipline drivers in carrying out deliveries, and lack of data management in the transportation system. To be able to solve this problem, several proposed solutions can be applied. The proposed solutions to overcome the root causes that should be applied by the company are to hire a document control, retraining the Standard Operating Procedure (SOP) for drivers, utilize transportation management system application, and apply incentive systems for drivers. In the future, it is recommended for PT. GRL to have a minimum standard in recruiting the drivers for example only recruit who possess a minimum of high school education to ease the completion of administrative tasks.

Al-Shabab and fundamental terrorism in Somalia
Authors: Chigudu Daniel
Published: May 2021

This study is motivated by threats faced by Somalia and other countries in fighting terrorism. Although several studies have attempted to explain the rise and dynamics of terrorism groups particularly al-Shabaab, this work is predicated more on how the terrorist activities threaten Africa and beyond informed by how these operations are sustained. This study aims to investigate threats to the continent and beyond by Al-Shabab and Fundamental Terrorism in Somalia.  In this study, a content analysis was used on quantitative and qualitative data obtained from publicly available datasets and secondary sources of research work on terrorism. The main contribution of this study is that, terrorism by the al-Shabaab is highly organized and that by skirting direct combat, the group has the potential for sustained fighting episodes despite waged campaigns to deter its spread. This is exacerbated by the reluctance to deploy many infantry forces from conventional armies to deal with the situation. The study may be useful to policymakers, terrorism experts, and scholars in accelerating measures of counter-terrorism.
