    Get PDF
    Many applications contain security features that are available for the end user to select and configure, as well as the ability to place the users in situation where they must take security related decisions. Web browser is one of these applications which consider as the only way to browse the internet. This study exposes the available security features in both of Internet Explorer and Mozilla Firefox in Microsoft Windows XP; moreover describes results of survey over 232 students in Universiti Utara Malaysia from different educational background to explore typical Internet user awareness and understanding toward web browser security features within windows XP through internet user behavior when using a Web browser to access the Internet. The study reveals some significant area of difficulty, with many standards security features presenting usable security challenge for large proportion of respondents. The results and finding highlight the lack of internet user understanding and awareness toward security features in the web browser

    The influence of objectivity, competence, and work performance on external auditors' judgements relating to the internal audit function in Jordan

    Get PDF
    This thesis presents empirical research on the perceptions of external auditors (EAs) regarding the impact of three dimensions of auditing, namely the objectivity of the Internal Audit Function (IAF), the competence of the IAF, and the work performance of the IAF, on (1) the effectiveness of the IAF in Jordanian companies listed on the Amman Stock Exchange (ASE) and (2) EAs’ decisions to rely on the work of internal auditors (IAs). In addition, this thesis investigates Jordanian EAs’ level of self-insight into the importance of the three dimensions when (1) evaluating the effectiveness of the IAF and (2) deciding on the degree of reliance on IAs

    This article introduces a broadband microstripline-based transmit/receive switch for 7-Tesla magnetic resonance imaging. The designed switch aims to handle a signal of multiple frequencies to/from a multi-tuned radio-frequency coil that resonates at frequencies corresponding to the speed of precession of a wide range of atomic X-nuclei, at the same time and without tuning. These include 1H, 23Na, 13C, 31P, 19F, and 7Li used in magnetic resonance spectroscopy as a measure to the existence of many diseases. The fundamental and third harmonic center frequencies of the switch are adjusted to resonate at two broadbands covering a wide range of atomic X-nuclei. Two section branch-line hybrid couplers with phase inverters are designed to build the broadband switch. The designed switch used the minimum trace widths of transmission lines that reveal a compact size without increasing the heat and then the loss beyond specific values. The couplers and the switch S-parameters exhibited good return loss (<-10 dB), high isolation (<-40 dB), less insertion loss (<1 dB) and two clear wide bands covering many atomic X-nuclei used in diagnosis, at the same time and without the need for any tuning circuit during operation

    A dual tuned transmit/receive (T/R) Switch for 7 tesla magnetic resonance imaging (MRI) that is based on concentric microstripline (MSL) coupler is introduced. The proposed switch is designed using two concentric MSL quadrature couplers on the top and bottom faces of the switch. The switch can be used to handle two frequency signals to/from two radio frequency (RF) coils. In this article, a 1H/31P atomic nuclei are excited. The two MSLs on the upper face of the switch are designed to transmit 298 and 120.6 MHz signals into RF coils, whereas each of the identical upper and lower MSLs are used to receive these signals from the RF coils. This switch can be used to transmit/receive signals from two RF coils at the same time, one work with 1H and the second with 31P atomic nuclei, and without any tuning. The proposed switch has been designed and simulated using the electromagnetic microwave studio computer simulation technology (CST). It demonstrates good matching (≈17 dB), low insertion loss (≈0.3) and high isolation (>70) for the 1H and 31P magnetic resonance signals at transmit mode. During receive mode, It demonstrates good matching (>20 dB), low insertion loss (≈0.2) and high isolation (>70) for the 1H and 31P magnetic resonance signals

    Egypt and the EU: An Assessment of the Egyptian Euro-Mediterranean Partnership

    Get PDF
    When the Euro Mediterranean Partnership Agreement (EMP) between Egypt and the European Union came into force, it was the first regional agreement of this kind to involve north-southsouth developing and developed countries. This type of regional agreements opened the door for many challenges facing the participating countries especially the developing ones. Therefore, this article is mainly concerned with a detailed assessment of the Egypt-Euro Mediterranean partnership Agreement through analyzing its objectives and instruments, providing an overview of the Egyptian EU economic relationship and the Egyptian economy\u27s benchmark data and basic economic indicators before and after the EMP. This article also discusses the Egyptian trade structure before and after joining the EMP. From this analysis, we reach the conclusion that since the EMP entered into effect, intra and interregional trade and FDI flows have increased significantly for Egypt. However, Egypt\u27s strong export growth and FDI inflows under EMP have not been translated into similarly strong economic and social progress. Indeed, the outcome of EMP has been disappointing with regard to key macroeconomic variables and social indicators. Since EMP came into effect, Egyptian GDP growth has been unstable. There is no evidence of accelerated change in the structure of production of the Egyptian economy since 1995; evidence shows that total employment has been the same since 1995, while the unemployment rate has been decreasing at a fairly low level

    Understanding and Predicting the Determinants of Consumers’ Acceptance and Usage of M-commerce Application: Hybrid SEM and Neural Network Approach

    Get PDF
    In m-commerce, privacy and security are major concerns. Existing research has examined the privacy and relationship, security, and intention to use. However, the determinants of privacy and security in mobile commerce remain largely unexplored. A study based on UTAUT2 and trust examines the factors that influence mobile commerce privacy and security. By using the approach of hybrid SEM/ANN analysis, it is possible to detect non-linear and non-compensatory relationships. According to linear and compensatory models, the absence of one determinant can be compensated for by another. The decision-making process of consumers is actually quite complex, and non-compensatory or linear models tend to simplify it. The sample is collected by using a mobile commerce application in order to gather 890 datasets on mobile commerce consumers. Findings: (1) Two determinants of M-commerce acceptance and use had an explicit and significant positive effect. Security and individual are two of these factors. (2) Privacy concerns have a severe negative impact on M-commerce acceptance and use. (3) Trust is found to partially mediate the effect on behavioral intentions of Security Factors (SCF), Privacy Factors (PRF), and Individual Factors (INF) on m-commerce in Jordan (INTENTION). According to the integrated model, m-commerce offers 71% privacy, security, and trust. Doi: 10.28991/ESJ-2022-06-06-018 Full Text: PD
