A numerical study of entropy and residual entropy estimators based on smooth density estimators for non-negative random variables
Authors: Chaubey Yogendra P. , Vu Nhat Linh
Published: March 2021

In this paper, we are interested in estimating the entropy of a non-negative random variable. Since the underlying probability density function is unknown, we propose the use of the Poisson smoothed histogram density estimator to estimate the entropy. To study the per- formance of our estimator, we run simulations on a wide range of densities and compare our entropy estimators with the existing estimators based on different approaches such as spacing estimators. Furthermore, we extend our study to residual entropy estimators which is the entropy of a random variable given that it has been survived up to time $t$.

The continuous development of information and technology (IT), demands its adoption in court institutions worldwide. Therefore, the application of e-court in Indonesia started after the publication of Supreme Court Regulation number 3 of 2018. The purpose of this article is to describe the adaptation of the Indonesian Supreme Court to the use of information technology, in an effort to improve its performance. This research focuses on two research problems, firstly, how is the regulation and implementation of electronic court in Indonesia? Secondly, what are the implications of accessing its application among justice seekers? A normative approach, which relates the broad access towards the justice seeker, was used. The implementation of IT in court processes is a reformative initiative, through innovation, efficiency, structure and system.  This advancement would also assist the judges in examining, judging and declaring a case. Socially, these further helps those who seek justice to cost effectively simplify and hasten the process, therefore mark a new era.

The Veneration and Visitation of the Graves of Saints in Soviet Central Asia
Authors: Exnerová Věra
Published: March 2021

The article contributes to the development of a deeper understanding of the changes in the practice of venerating and visiting of the graves of saints in Central Asia during the Soviet period. For this purpose, the article explores the archival reports and oral histories from the region of the southern Ferghana Valley in Uzbekistan from the 1920s to the1980s. The article reveals that the broad “categories” often used to study the issues associated with the graves of saints and their visitation, such as the ideological conflict between communist politics and Islam, or the gap between normative and popular Islam, are largely insufficient when describing the practice during this period. The common “schemes” are blurred or interconnected – “believers” used the Soviet system to fulfil their goal of venerating the graves of saints, while the local authorities often helped to retain the practice, or eliminate it, as determined by the needs of their own career advancement. In addition, the process of hagiography continued under the new conditions, irrespective of the levels of education or the individual stances towards the state that existed among the different actors. For the most part, people learned how to combine both Soviet modernity and the veneration of the graves of saints in innovative ways. This analysis contributes to the innovative research process in relation to Islam in Soviet Central Asia. The article also seeks to contribute to the recent debate about the graves of saints and the gap between normative and popular Islam.

Until recent time, Migration, a veritable tool for industrial enhancement, economic development, political inclination, scientific and technological discoveries, and social obligations has ironic positions, whose another view, geared by exploitation from the mid-twentieth century to twenty-first century, somewhat affects the centuries before them. This is made possible through its inclusion of illicit transactions, such as labour and commercial sexual exploitation, human trafficking, forced labour, child soldiers, drug trafficking, domestic servitude, and the removal of organs or tissue for sale as portrayed in ABC Duruaku’s A Mirage for a Dream. This menace is meticulously alarming especially in the Nigerian state in the 21st century. This cankerworm, caused by corruption, poverty, weak governmental system and unemployment ultimately triggered malicious activities like prostitution, armed robbery, kidnapping, incessant killings, and rape, thus, increased pain, suffering, sickness and death among the people and ridicules the identity of the Nigerian nation, thereafter, threatens its existence as a sovereign states. Amongst the major findings is that human trafficking has created a lot of creative punches and dramatic representations by critics and dramatists over the years, yet the issue is heinously prevalent. The study therefore aims at interrogating the connection between migration and human trafficking in the Nigerian society, as portrayed in ABC Duruaku’s A Mirage for a Dream. To achieve this, General System Theory and Content Analytical Methodology are employed. The study, therefore, recommends the establishment of an agency to monitor all cases of migration and human trafficking in the Nigerian state.

The effects of financial crises on economic growth of countries are destabilizing and research interests in this area in the case of Nigeria has not be sufficiently exhibited, hence, this study. The study examined the effect of financial crises on economic growth in Nigeria using time series data that covered a period from 1986 to 2019. For data analysis, the major empirical tools utilized are Autoregressive Distributed Lag (ARDL) Co-integration and ECM techniques, following the result of the unit root tests that revealed mixture of I(0) and I(1). The ARDL Co-integration result revealed that long run relationship exists among the selected variables of interest in this study. Furthermore, ECM technique revealed that Financial Crises have negative and significant effect on Economic growth in Nigeria both in the long run and short run. Also, the effect of current value of Inflation was found to be negative and significant in the long run and that of Trade openness was positive and statistically significant in the short run. Also, the study found that there are long run and short run positive and significant impacts of Liberalization on Economic growth. Finally, the findings revealed that the current year values of Money Supply have negative and significant impact on current Economic growth; however, its past value has positive impact. The study concluded that a long-run relationship existed between financial crises and economic growth; specifically, such crises have negative and significant effects on economic growth of Nigeria. The government in general should tinker with the current policy prescription regarding the establishment of financial institutions especially those that cannot qualify for the status of domestically systematically important to avert recurring crises in the financial sector that have impacted the macro-economy negatively.

The study analyses the moderating effect of financial performance on the relationship between board characteristics and dividend policy of listed non-financial firms in Nigeria. Board characteristics is proxied by board composition, board size, and board diversity, while dividend policy is proxied by dividend pay-out ratio. The positivist research paradigm and correlational research design were used. Relevant data for the study were collected from 39 sampled non-financial firms actively trading on the floor of the Nigerian stock exchange (NSE) from 2008 to 2017; the data collected were analysed using the panel corrected standard error (PCSE) regression analysis. The findings reveal that board composition and board diversity have positive but insignificant effect on dividend pay-out ratio of non-financial firms before moderation, While, board size has positive and significant effect on dividend policy of listed non-financial firms before moderation. The study also found that financial performance moderate the relationship between board characteristics and dividend pay-out ratio of listed non-financial firms. Based on the findings, the study concludes that board composition and board size are related with high dividend payment. Among the important policy implications is that the variable of board size used suggest that there is the need by SEC to monitor the available cash at the discretion of managers since financial performance can moderate the relationship between board size and dividend pay-out ratio in order to mitigate agency conflict between management and shareholders of listed non-financial firms which is in-line with the practical problem of the study. It is therefore recommended amongst others that the government through the regulators should provide an enabling environment for non-financial firms to make a profit and pay more dividends to their shareholders since the interaction effect of financial performance makes the variables of the study to be more active in influencing the dividend pay-out ratio of non-financial firms in Nigeria.

The Neighbourhood Principle presupposes that everyone in the vicinity knows each other and this makes it easier to monitor deviants in the society. Hence, the case for state policing in Nigeria in view of the upward surge in crime wave in this country. Data was obtained from secondary sources which include books, periodicals, journals, newspapers, the internet etc. Data was analyzed using the method of content analysis. The theory of social conflict (Coser, 1956) was adopted as the theoretical framework of the study. Results revealed that the success story of state policing in the United States was as a result certain factors-technology advancement, level of motivation, institutions and infrastructures, psychological and intellectual disposition of officers and even the acceptance of state policing by the society. These are all lacking in Nigeria. Thus, it was suggested in this study that the idea of state policing should be rested for now while the society works on her vital infrastructures, institutions, etc.

Fast Moving Consumer Goods are products that are required by almost all users in their day today life. The advertisements for these products need more attention in terms of creating responsiveness among the consumers for their purchase decision. However, consumers are bombarded with lots of information through multiple media like newspapers, magazines and internet but remain engaged from time to time hence lack time to update themselves. This has made it difficult for advertisers to trap consumers hence resort to outdoor messages to reach the target people. Extant studies on the out of home advertising have attempted to elucidate on the challenges of advertising and the attendant supposed solutions, conversely, most of the extant research focus more on developed countries than developing countries such as Nigeria. Hence, this study examined the effect of Out-of-Home Advertising on consumer buying behaviour of selected fast moving consumer goods in Lagos State, Nigeria. Survey research design was adopted for the study. The population of the study consists of individuals living in Lagos State with total number of 2,556,300 and with the sample size of 520 derived from Taro Yamane method. Data was collected using self – administered structured questionnaire and validated for a response rate of 93.4%. Cronbach Alpha reliability for major constructs had an average of 0.80. Random sampling technique was used. The data collected was analysed using simple linear regression. Findings revealed that there is a strong positive and significant relationship between Out-of-Home Advertising and consumer buying behaviour(β= 0.834; R2= 0.695; t(520) = 33.225; p>0.05). The study concludes that Out-of-Home Advertising has significant and positive effect on consumer buying behaviour and recommends that the study findings led to the recommendations that producers of fast moving consumer goods should focus more on out of home advertising such as use of billboards as opposed to other forms of media like T.V and Radio to help boost consumption and sale of their products. The study also recommends marketers of FMCGs to enhance the knowledge and awareness of consumers with regard to existence and location of billboards.

Published: March 2021

Cloud computing—delivering infrastructure, services, and software on demand via the network—offers attractive advantages to the public sector. It has the potential to reduce information and communications technology (ICT) costs by virtualizing capital assets like disk storage and processing cycles into a readily available, affordable operating expense. Unfortunately, architects more often than not assume that simply adding another server into the mix can fix any performance problem and security issues. Cloud is a platform shuffle that enables a fierce and contentious debate on the issues of security and performance surrounding how to secure information and instantiate trust in an increasingly open and assumed-hostile web operating environment. When you start adding new hardware/update existing hardware in a web cloud, the complexity starts increasing which affects performance and hence security. Here we will define the algorithms to keep both performance and data secure but flexible enough to allow for expandability. In this paper, we have highlighted the following critical issues for the leading Cloud Computing such as Characteristics of cloud computing, threats and performance analysis. This paper specifically discuss about the below-mentioned in detail.

Published: March 2021

In this study, nano Fe2O3 particles were synthesized by the combustion of gel from polyvinyl acohol (PVA) and tartaric acid (TA) for the degradation of methyl blue (MB) from the aqueous solution by the photocatalytic process. Factors affecting on Fe2O3 formation such as the pH of solution, temperature of gel formation, mole ratio of TA/PVA, temperature of calcination were investigated. The structure, morphology of Fe2O3 particles were characterized by analysis methods such as Differential Thermal Analysis, X- Ray Diffraction and Field Emission Scanning Electron Microscopy. The results showed that single-phase Fe2O3 was smaller than 60 nm of average grain size. When using Fe2O3 to investigate the photocatalytic capacity under the visible light irradiation, the results indicated that Fe2O3 catalysts showed a rather high photocatalytic ability to decompose MB. The intermediates coming from the photocatalytic degradation were identified.

Published: March 2021

The diamond oil field is located in Blocks 0102 Offshore Vietnam. Crude oil from Diamond Well Head Platform (WHP) is evacuated to FPSO via 20 km - 10” subsea flexible pipeline. The lowest seabed temperature in the field is 22˚C, while the pouring point temperature of this crude oil is very high (36˚C) due to high paraffin content (about 25% by weight). So studying to synthesize a copolymer use to reduce the pour point temperature of this oil is very important. The copolymer must have the ability to reduce the pour point temperature of the crude oil from 36˚C to 21˚CThe synthesis process occurred via copolymerization of acrylate, methacrylate and vinyl acetate monomers using the free radical polymerization method in Solvent 100 as a solvent. There are many factors that affect copolymerization reaction and therefore they will impact the structure and performance of the said copolymer. One of the most important factors is the ratio of initiator to monomer in the reaction.Therefore the aim of this research is to choose an appropriated ratio of initiator to produce a copolymer that can reduce pour point temperature of Diamond crude oil from 36˚C to 21˚C at a dosage of 1.750ppmv

Reconstrucción facial con colgajo libre lateral del brazo
Authors: Ramírez Carlos Alberto Centeno , Rodríguez Madelein Centeno
Published: March 2021

Las lesiones faciales malignas complejas o muy extensas, tratadas mediante resección quirúrgica, a menudo constituyen un reto para el cirujano plástico, debido a la gran exposición social del sitio, así como la escasa oferta de tejido para la reconstrucción del defecto cutáneo residual. En estos casos es imperativa la obtención de márgenes libres de malignidad; en segundo lugar, intentar recuperar la funcionalidad del área quirúrgica, y por último, buscar resultados estéticos favorables. Cuando sea posible, la ausencia de cobertura cutánea debe ser restaurada con tejido de similar grosor, color y textura, para lo cual el cirujano debe evaluar cuidadosamente el tamaño del defecto, la localización, las capas de tejido involucradas, la relación con estructuras aledañas y la cantidad de tejido donador disponible, con el fin de conseguir el mejor resultado final. Para deformidades de gran extensión que involucran múltiples capas de tejido, el concepto del triángulo reconstructivo de Mathes y Nahai, puede brindar mejores resultados, dándole opción al cirujano de escoger entre transposición de colgajos locoregionales, colgajos libres o expansión tisular. Los colgajos libres pueden satisfacer mejor las necesidades de forma y función facial, y permiten una considerable oferta de tejido con adecuada vascularidad, similitud de color, textura y grosor. A continuación se presenta el caso clínico de un paciente masculino de 21 años con el diagnóstico de carcinoma basocelular de mejilla derecha recidivante, quien fue sometido a resección completa y reconstrucción del defecto mediante transferencia libre de un colgajo lateral del brazo derecho, con excelentes resultados anatómicos y funcionales.

El virus Chikungunya produce una enfermedad de reciente aparición y creciente incidencia en Costa Rica. Lasmanifestaciones crónicas de la enfermedad se consideran de importancia en el área de la reumatología. La pacientepresentó factores de riesgo para cronicidad como el sexo, la duración y severidad de la fase aguda, el número de articulaciones comprometidas y la asociación con el síndrome de activación macrofágica. En una artritis idiopática juvenil, que es el principal diagnóstico diferencial, se esperaría un inicio más insidioso y no agudo como en este caso; además, la paciente no presentó hepatomegalia o serositis e inicialmente no tuvo trombocitosis, pero manifestó un síndrome de activación macrofágica, que es una complicación inflamatoria descrita en artritis idiopática juvenil. La remisión del cuadro de artritis crónica con el uso de metotrexate, no ayuda al diagnóstico diferencial, porque se ha reportado que este es el tratamiento crónico de elección en ambas patologías. En este reporte se presenta el caso de una paciente pediátrica que ingresó con un cuadro agudo de Chikungunyaconfirmado serológicamente, y que evolucionó con criterios de una artritis idiopática juvenil sistémica y un síndrome de activación macrofágica secundario.

Published: March 2021

The conceptual paper is based on ethics and social responsibility towards environmental and sustainable development. The great challenge of the twenty-first century is raising people everywhere to a modest standard of living while preserving as much of the rest of life as possible. We've reached a point where we have to end the burden we've placed on the Earth. Socially Responsible enterprises are those which operationalize their corporate responsibilities in their strategies and business practices keeping in mind better relationships with their stakeholders and focussing to maximise environmental sustainability. The concentration of the company should not only cover one aspect, but responsibility should also be applied into the core values of the company, in order to enable maximum performance. The main focus of the study is socially responsible enterprises and their responsible marketing strategies. Sustainability has always been an important concern for the manufacturing sector and consumer demand for environmentally conscious products is also increasing. A large number of manufacturers have come up with ideas to get advantage from business practices which are sustainable. Manufacturing through viable techniques will
create products with the help of processes which are economical and that curtails negative environmental impacts simultaneously conserving energy and natural resources. Responsible marketing is using eco-friendly materials, using less paper, using more digital technology to save on materials and cost of delivery. Many companies have started taking "sustainability" as a very important factor while making planning and marketing strategies to elevate and increase the global market. Changes in this industry have reached well beyond the boundaries of just going "green," and now it also includes many big business houses across different industries. In today’s business world, these efforts are having significant results.

The academic needs of African-American girls too often are not linked to their intersecting identities. These interlocked identities often go unseen, thus are rarely addressed in K-12 schools. Specifically, their identities are neglected in some of their English Language Arts classrooms through the sole use of hegemonic literary practices. Literacy 4 Brown Girls was implemented at a Midwest school for twelve weeks. The purpose of this case study was to explore the ways in which a literacy collaborative, designed with the identities of African-American girls in mind, might impact the identity construction of 12 African-American girls at a local school. Through careful document analysis, findings from this study reveal that African-American girls require school programs that focus on honoring, uplifting, and supporting the construction of their intersecting identities. Not doing so posits that the identities of African-American girls are unimportant and perpetuates their academic neglect and disengagement.
Actores, coaliciones y cambio institucional: la política social ante la reversión conservadora en Argentina y Brasil
Authors: Gaitán Flavio
Published: March 2021

El artículo se propone analizar los cambios en las variedades de capitalismo de bienestar de Argentina y Brasil en el contexto de la transición política representada por la llegada al gobierno de coaliciones conservadoras, por medio de elecciones, en Argentina y a través de un irregular proceso de juicio político contra la presidenta Roussef, en el Brasil. El artículo analiza específicamente las políticas de seguridad social, las transferencias no condicionadas dirigidas a los “outsiders” y la regulación del mercado de trabajo. Por un lado, se presentan los cambios en las políticas públicas. Por otro, utilizando un marco teórico referenciado en las coaliciones, comunidades epistémicas y cambio institucional, buscamos entender las fuerzas dinámicas detrás de los cambios operados en materia de protección social.
Between Opportunism and Limitation: the resurgence of populism and the right-wing populist ‘Alternative for Germany’ (AfD)
Authors: Selk Veith , Sonnicksen Jared
Published: March 2021

The article provides first an overview of the strands of current research on populism and the German newcomer party, the Alternative für Deutschland (AfD). Building upon this, it will be demonstrated how the AfD constitutes a right-wing populist party, but also how its ideology connects to ideational-historical currents that have been influential in the Federal Republic of Germany. Finally, we elaborate the underlying thesis that the AfD comprises a party that is oriented primarily toward re-adjusting and re-setting borders. Accordingly, the party manages to successfully politicize the cleavage between supporters of more openness and supporters of stronger delimitation.
A desaceleração chinesa e o “Novo Normal”: implicações estruturais para a economia e o setor financeiro doméstico

Published: March 2021

Após décadas de crescimento econômico robusto, facultando crescente proeminência geopolítica no sistema interestatal capitalista, a China dá sinais de desaceleração em meio a profundas mudanças e incertezas em seu regime produtivo. Conforme a estratégia de desenvolvimento prévia, com forte participação dos investimentos e do desempenho exportador, parece esgotar-se, um novo cenário se desenha, com distintas oportunidades e riscos. Assim, mediante dados empíricos e literatura pertinente, este trabalho fará uma reflexão conjuntural sobre o paradigma do “Novo Normal” e seus desdobramentos para a trajetória futura da potência asiática, problematizando possíveis transformações na interlocução entre instituições de Estado e de mercado, principalmente no setor financeiro.
Comparing estimation techniques for timescale-dependent scaling of
climate variability in paleoclimate time series

Abstract. Characterizing the variability across timescales is important to understand the underlying dynamics of the Earth system. It remains challenging to do so from paleoclimate archives since they are more than often irregular and traditional methods to produce timescale-dependent estimates of variability such as the classical periodogram and the multitaper spectrum generally require regular time sampling. We have compared those traditional methods using interpolation with interpolation-free methods, namely the Lomb-Scargle periodogram and the first-order Haar structure function. The ability of those methods to produce timescale-dependent estimates of variability when applied to irregular data was evaluated in a comparative framework using surrogate paleo-proxy data generated with realistic sampling. The metric we chose to compare them is the scaling exponent, i.e. the linear slope in log-transformed coordinates, since it summarizes the behaviour of the variability across timescales. We found that for scaling estimates in irregular timeseries, the interpolation-free methods are to be preferred over the methods requiring interpolation as they allow for the utilization of the information from shorter timescale which are particularly affected by the irregularity. In addition, our results suggest that the Haar structure function is the safer choice of interpolation-free method since the Lomb-Scargle periodogram is unreliable when the underlying process generating the timeseries is not stationary. Given that we cannot know a priori what kind of scaling behaviour is contained in a paleoclimate timeseries, and that it is also possible that this changes as a function of timescale, it is a desirable characteristic for the method to handle both stationary and non-stationary cases alike.
Introduction: Intergenerational Transmissions of Infant Mortality using the Intermediate Data Structure (IDS)
Authors: Quaranta Luciana , Sommerseth Hilde Leikny
Published: March 2021

It has previously been shown that infant mortality clusters in a subset of families, a phenomenon which was observed in historical populations as well as contemporary developing countries. A transmission of death clustering across generations has also been shown in Belgium, but it is unknown whether such effects are specific to the studied context or are also found in other areas. The current article introduces a special issue devoted to analysing intergenerational transmissions of infant mortality across the maternal line in Belgium, the Netherlands, northern and southern Sweden, and Norway. Taking advantage of the Intermediate Data Structure (IDS), the five empirical studies created datasets for analysis and ran statistical models using exactly the same programs, which are also published within the special issue. These works are the first set of studies using the IDS on several databases for comparative purposes. Consistent results across the studied contexts were shown: transfers of infant mortality across the maternal line were seen in all five areas. In addition, the works have shown that there are large advantages of adopting the IDS for historical demographic research. The structure has in fact allowed researchers to conduct studies which were fully comparable, transparent and replicable.
Determinant Analysis Of Conflict On Project Results In Aceh Province

Published: March 2021

The project is an activity with a target that must be completed within a certain period, where in its implementation often obstacles arise between the elements involved in it. Problems that arise must be immediately handled properly and appropriately so that the achievement of results is as expected.. Conflict is a condition of the oc-currence of discrepancies between values or goals to be achieved, both existing in individuals and in relationships with others. The purpose of this research is to find out one of the main factors causing conflict in project implementation. The method used in this study is a combined method, namely quantitative and qualitative methods through the distribution of questionnaires with the limitation of project observations from 2009-2011 that have been completed, with funding coming from the Aceh Budget (APBA). Designation of respondents for all classifications of construction services, from medium classification (M) to large classification (B). Population Construction executing services from the data obtained were 502 contractors, using the Slovin formula found a sample of 84 contractors. The independent variables reviewed are the owner factor and the project condition factor, while the dependent variable is the success of the project.

Liwa Botanical Garden is located in West Lampung Regency which has an area of 86.6 hectares and is one of the conservation of ornamental plants that presents the flora of the Bukit Barisan Selatan National Park. One of the flagship collections of this botanical garden is a native orchid. Disease infection is still a major obstacle in the cultivation and development of native orchid potential at Liwa Botanical Garden. Based on the results of previous studies, it is known that several individual natural orchid collections from Liwa Botanical Garden showed symptoms of fungal disease infections. Disease infections can inhibit plant growth and resistance and reduce the aesthetic value periodically. Symptoms of infection include necrotic patches on the upper surface of the leaf. This research was conducted to determine the identification of diseases and efforts to protect native orchids against fungal infections at Liwa Botanical Garden through a collection of samples that showed symptoms of infection, analysis of disease symptoms, and analysis of disease resistance levels. The results showed that the response of the native orchid at Liwa Botanical Garden to fungal infections was showed symptoms of wilting in the leaves, namely in the orchids Eria sp., Dendrobium sp., and Cymbidium sp. turns black on the edge of the leaf, Thrixspermum sp. The type of orchid most commonly infected with fungus is Cymbidium sp. a total of 8 samples, and Thrixspermum sp. 3 samples, Eria sp. as many as 4 samples, Dendrobium sp. and Calanthe triplicata as many as 6 samples. The type of native orchid that is most susceptible to fungal infections is Dendrobium sp. and Eria sp. with disease intensity of 74.11% and 22.3%. The results of this activity are expected to be basic information in efforts to protect plants against diseases to support the application of conservation of native orchids on Liwa Botanical Garden.
