Therefore, public sectors interact with many individuals;utilizing this technology lowers costs, enhances services, boosts efficiency, and saves time. The Government of Saudi Arabia has had various obstacles in serving its populace. Poor service delivery and excessive Government operating costs resulted from this manual service delivery. As a result, the Government launched the E-Government systems, which provide services more quickly. As a result, the report covered Saudi Arabia’s efforts to adopt E-Government, its difficulties, and its objectives to advance the 2030 vision. This study examined the adoption of E-Government systems using the Unified Theory of Acceptance and Use of Technology (UTAUT) in Saudi Arabia. A sample size of 200 was estimated using the Convenience approach and received 58% of the response from employees and end-users of the E-Government systems. Data were analyzed using MS-Excel and SMART PLS for testing the hypothesis and applying the Partial Least Square approach. The results of the hypothesis testing reveal several meaningful relationships, including relative benefits, compatibility, security, management support, performance expectations, perceived Usefulness of E-Government, ease of use by reducing uncertainty to E-Government, and IT infrastructure by reducing language on E-Government adoption.展开更多

Design/methodology/approach: Drawing on the unified theory of acceptance and use of technology (UTAUT), and integrating perceived enjoyment, we put forward a theoretical research model of factors affecting continuance intention of mobile reading. Using 186 valid data collected through a questionnaire survey, we conducted data analysis with the partial least squares structural equation modeling (PLS-SEM). Findings: The results show that performance expectancy, effort expectancy, social influence and perceived enjoyment all have positive impacts on continuance intention. Among them, perceived enjoyment has the most significant effect on continuance intention, followed by performance expectancy. In addition, effort expectancy significantly influences perceived enjoyment. Contrary to our expectation, facilitating conditions have no impact on continuance intention. Practical implications: This study could help mobile data service providers to foster users' continuous usage of mobile reading. Research limitations: This study focused only on the effect of perceived enjoyment as an internal motivation on continuance intention of mobile reading, and other possible factors were not considered. Also, continuance intention may be different from the actual behavior. Furthermore, data of student users was collected from one university in China, and was cross-sectional, while working samples were not considered. Originality value: This study considers the effects of both external and internal motivation on continuance intention of mobile reading. The results highlight the role of perceived enjoyment in building users' continuance intention of mobile reading.展开更多

Maia Creus and Ines Martins are parts of the research group TADD (Theory, Analysis, Design, and Development) recognized by Ramon Llull University. The research, based on feminist and performance studies, focuses on artistic groups currently working in Catalonia and whose practices produce tools and technology sharing, highlight the social and educational potential of ICTs (information and communication technologies) free access when used, consciously and critically, from feminist perspectives assumed. The research project was developed as a dual methodological process. This research group has developed a critical review of the three conceptual axes--women, art, and technology--around which revolves the present study and, in parallel, has conducted field work directly with groups of selected artists, in order to meet them within their areas of production and to know more about their working methods, theoretical discourse, goals, frustrations, and desires. This deployment in parallel was used to develop a group of key concepts that revolve around "free culture" and "culture of access" that in contrast with the practices and theories of the investigated groups are necessary to intercept and reinterpret. Through various forms of visibility, this paper intends to investigate, promote, and share these tools, technologies, and pedagogies developed by these groups which, by its own dynamics of collective work, as well as the processes of public participation, emphasize forms of interculturality and interdisciplinary.展开更多

Therefore, mobile search service providers are eager to know which factors most influence user acceptance of mobile searches. Based on the characteristics of mobile searches and a review of previous information technology acceptance research, this study integrates the task technology fit model and the unified theory of acceptance and use of technology model to develop a mobile search acceptance model and empirically tests this model. This study finds that, for mobile searches, the performance expectancy, social influence, and perceived cost all significantly influence use intention and the performance expectancy increases with the increasing user's experience and higher tasktechnology fit degree. The effort expectancy is found to not affect the use intention of mobile searches and the users' gender does not have a significant moderating effect on the use intention. The results are then used to develop suggestions for mobile search providers to promote their application and development.展开更多

Oviductus Ranae is one of the best-known and highly valued oriental foods and medicines. Traditional Chinese medicine holds that Oviductus Ranae can nourish yin, moisten lung and replenish the kidney essence. Meanwhile, activities of Oviductus Ranae such as anti-aging, anti-lipemic, anti-oxidation and anti-fatigue have also been demonstrated by modern phar-macological studies. Previous studies have shown that Oviductus Ranae is mainly composed of proteins, which are up to 50% or more.展开更多

To eliminate inter- symbol interference caused by multipath propagation, spatial diversity equalization is the main technical means. The paper combines the passive phase conjugation and spatial processing to maximize the output array gain. It uses signal-to-noise-plus-interference to evaluate the quality of signals received at different channels. The amplitude of signal is weighted using Sigmoid function. Second order PLL can trace the phase variation caused by channel, so the signal can be accumulated in the same phase. The signals received at different channels need to be normal- ized. It adopts fractional-decision feedback diversity equalizer (FDFDE) and achieves diversity equalization by using different channel weighted coefficients. The simulation and lake trial data processing results show that, the optimized diversity receiving equalization algorithm can im- prove communication system's ability in tracking the change of underwater acoustic channel, offset the impact of multipath and noise and improve the performance of communication system. The performance of the communication receiving system is better than that of the equal gain combination. At the same time, the bit error rate (BER) reduces 1.8%.展开更多

The simulation and lake trial data processing results show that, the optimized diversity receiving equalization algorithm can im- prove communication system's ability in tracking the change of underwater acoustic channel, offset the impact of multipath and noise and improve the performance of communication system. The performance of the communication receiving system is better than that of the equal gain combination. At the same time, the bit error rate (BER) reduces 1.8%.
文摘This paper introduces a tunable external-cavity diode laser using a MEMS vertical mirror fabricated on a silicon-on-insulator (SOI) wafer. This laser has the merits of simple alignment process, easy integration/packaging, and potentially large wavelength tuning range.
文摘Gene amplification is a common mechanism of oncogene activation and contributes to tumor progression. Analysis of such genetic alterations are relevant to the understanding of tumor genetics and could provide prognostic information for the individual patient. Standard analytical approaches using Southern blot and slot blot require a large amount of good
