Proposing an e-government stage model in terms of personal information security in developing countries
No full textWith improvements in Internet technology, the majority of governments throughout the world have adopted Information and Communication Technologies (ICTs) to deliver more efficient and effective services to their agencies, companies, and people. In general, e-Government refers to the use of information and communication technologies (ICTs) by government agencies to offer and improve public service delivery. Developing countries are extremely enthusiastic about implementing e-government. But these emerging countries are still in the beginning stages of development and suffer from shortages. In e-government, individuals are concerned about their privacy since e-government frequently deals with personal information. This article studies the concerns and obstacles that affect personal information security in e-government, taking into account the majority of security viewpoints, this research proposes models of e-government from perspective of protecting personal data. The study is qualitative in terms of methodology, it depends on documentary studies, content analysis and comparative study. © 2022 IEEE
Evaluating a proposed e-government stage model in terms of personal data protection
Full text linkIn today's era, the e-government plays a significant role in providing better services to citizens. As a result, citizens are crucial in ensuring the success of the e-government and are involved in the government's policies. Hence, the protection of personal information must be taken into consideration when designing any e-government model. Previous studies have shown that privacy and security are the main challenges in implementing an e-government in developing countries. This study aims to evaluate an e-government stage model that is proposed based on protecting personal information in developing countries. The methodology of this study uses SOAR (Strengths, Opportunities, Aspirations, and Results) analysis to evaluate the stages and combines it with the Analytic Hierarchy Process (AHP) to determine the feasibility of the model. The results of the study show that the model is acceptable and suitable for adoption. Therefore, the model is a viable option for implementing an e-government in developing countries
Evaluating an E-government stage model by using SOAR-AHP process
Full text linkE-government is a key component of today's efforts to give citizens improved services. As a result, participation of the general public in government policy is essential to assuring the success of e-government. Thus, when developing any e-government model, the security of personal information must be taken into account. According to earlier research, the developing countries are suffering from implementing e-government to provide e-services for their citizens. They also indicate that the biggest obstacles to implementing e-government in such countries are security and privacy. This study attempts to assess e-government stage model via using SOAR (Strengths, Opportunities, Aspirations, and Results) and Analytic Hierarchy Process (AHP). This is a new and reliable technique for evaluating e-government prior implementing. The AHP is combined with the SOAR analysis in this study's approach to analyze the phases and assess the model's viability. The study's findings demonstrate that the model is workable and appropriate for adoption
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Analiza i ocena wydajności energetycznej protokołów routingu sieci MANET
No full textRecently, the lack of independent wireless networks deployment was the main reason not only loosing victims but also diminution of the performance of security forces and first aids services during natural disasters and wars. Mobile Ad Hoc Networks (MANET) is the technology of choice used in such critical situations where the infrastructure of wireless networks fails to work. MANET relies on its nodes to forward and route packets that gives it a characteristic of an independent network. The independence here means that the network relies on its battery power to achieve its routing. In this research work, we study two types of MANET protocols belonging to different kinds of routing protocol categories: namely reactive protocol and proactive protocol in terms of power consumption. More specifically, we are interested on the Destination-Sequenced Distance-Vector (DSDV), Optimized Link State Routing (OLSR), Ad Hoc On-Demand Distance-Vector (AODV) and Dynamic Source Routing (DSR) protocols to investigate how much power they consume at different layers, operation modes, routing overhead and MAC load. In order to achieve the goal of performance study, we choose some scenarios that can be adapted to different MANET contexts: such scenarios carried out when network area size, network density, pause time and mobile node speed are changing. Extensive simulations and results for these scenarios obtained by NS2 simulation software.Recently, the lack of independent wireless networks deployment was the main reason not only loosing victims but also diminution of the performance of security forces and first aids services during natural disasters and wars.

Mobilne sieci Ad Hoc (MANET) to technologia wybierana w krytycznych sytuacjach, w których infrastruktura sieci bezprzewodowych przestaje działać. MANET opiera się na swoich węzłach, aby przekazywać i kierować pakiety, dzięki czemu mają one charakterystykę niezależnej sieci. Ta niezależność oznacza, że sieć bazuje na mocy baterii w celu osiągnięcia odpowiedniego routingu. W tej pracy badawczej badamy dwa typy protokołów MANET należących do różnych rodzajów kategorii protokołów routingu: mianowicie protokół reaktywny i protokół proaktywny pod względem zużycia energii. W szczególności, jesteśmy zainteresowani protokołami DSRV (ang. Destination-Sequenced Distance-Vector), zoptymalizowanym routingiem stanu łącza (OLSR), protokołami ADHoc On-Demand Distance-Vector (AODV) i Dynamic Source Routing (DSR) w celu sprawdzenia, ile mocy zużywają poszczególne warstwy, tryby działania, obciążenie routingu i obciążenie MAC. Aby osiągnąć cel - badanie wydajności, wybieramy pewne scenariusze, które można dostosować do różnych kontekstów MANET: takie scenariusze zachodzą, gdy zmienia się rozmiar obszaru sieci, gęstość sieci, czas przerwy i prędkość węzła mobilnego. Uzyskano rozbudowane symulacje i wyniki dla tych scenariuszy przy użyciu oprogramowania symulacyjnego NS2
