Impacts of virtual amenities on residential relocation and decentralization of megacity: An empirical study in wuhan, China

Clarifying the impact of urban virtual amenities (VAs) based on online and offline services on residents and urban spaces is important in the context of mobile internet access. However, the measurement of VA usage and its association with urban space have limited its theoretical development. This study identifies relocation directions through changes in residential locations and measures the four types of VA usage via mobile app data. An ordered logistic regression model is constructed to measure the correlation between VA usage and residential locations. The results show a significant association between VA usage and residential location. Residents who use VA-shopping are inclined to live outside the central region, while the opposite is true for residents who use VA-life and VA-public service. Because the users and usage intensity of VA-shopping are greater than those of other services, we summarize the VAs that drive outward relocation and urban decentralization because virtual amenities liberate the constraints on residential mobility imposed by the proximity of functional urban amenities. The findings are informative for understanding urban spaces under mobile ICTs and conducting behavior research on virtual-real interactions.

Managing future cities: media and information and communication technologies in the context of change

Abstract Purpose The goal of this paper is to examine the usage of information technologies and media in two European case studies – Berlin and Warsaw. Findings from the research can be used to create urban policies and media infrastructure design, based on the different strategies of two European cities. Berlin and Warsaw have taken different paths in implementing the smart city concept, adapting the idea to their economic, historical, and social realities. Media are understood here as human-machine and machine-machine communications, and also in terms of both physical and digital media infrastructure. Methodology The research aims at examining strategies and institutions (both private and public) in light of the practical implementation of smart solutions by City Hall authorities. The study combines analysis of grey literature (news reports, corporate strategies, City Hall documentation) with qualitative research: 30 semi-structured interviews conducted with local municipalities and city planners in both cities. Findings Findings are likely to provide evidence potential drivers and barriers to the implementation of smart city solutions. The results provide evidence that media and information technologies in the city are implemented due to the data policies of entities that usually implement smart city strategy independently. The task of city authorities is to guarantee access to basic infrastructure, which is the basis for creating other solutions by private entities. Practical implications The empirical research is likely to provide evidence that Berlin and Warsaw have not yet fully appreciated the solutions based on communication between machines, but there is increasing use of ‘ad hoc’ solutions. Social implications This study may be used as a source of information for smart city managers, media infrastructure, and urban strategy with a focus on residents and information and communication technologies. Findings are addressed to media and urban experts and scholars, as well as sociologists, political scientists, engineers, ICT specialists, policy-makers, city managers and citizens. Value The study shows the growing importance of mobile devices, media-like services and ICT have resulted in changes in City Hall’s development strategies and new theoretical approaches through which the cities might be analysed. This study finds that networks, platforms and media infrastructure have been used to describe new ways of communication between city authorities, citizens and machines. It has been argued that fostering an advanced media infrastructure (soft and hard) has the potential to create “The Future City”.

Technology-Enhanced Language Learning: A Meta-Analysis Study On English Language Teaching Tools

This meta-analysis study explores the effectiveness of technology-enhanced language learning in the context of English language teaching. Through a comprehensive review of relevant literature, various research studies were examined to gain insights into the impact and potential of technology in language learning. The findings highlight that the use of new technologies positively contributes to learners' language learning skills and enhances their overall proficiency. Mobile learning and ICT tools have been identified as effective resources that facilitate English language learning by providing accessible and efficient learning environments. Additionally, the research indicates that technology-supported language learning is as effective as learning with human teachers, indicating the potential of technology to offer personalized and tailored learning experiences. However, it is crucial to provide teachers with proper training and support to confidently integrate technology into their teaching practices. Educational institutions should offer comprehensive training programs and allocate sufficient time for teachers to enhance their technological skills and confidently utilize educational technologies. These findings underscore the importance of technology in enhancing language learning outcomes and emphasize the need for ongoing support and professional development for teachers in integrating technology into language teaching.

Application of Gaussian Mixtures in a Multimodal Kalman Filter to Estimate the State of a Nonlinearly Moving System Using Sparse Inaccurate Measurements in a Cellular Radio Network.

Kalman filter is a well-established accuracy correction method in control, guidance, and navigation. With the popularity of mobile communication and ICT, Kalman Filter has been used in many new applications related to positioning based on spatiotemporal data from the cellular network. Despite the low accuracy compared to Global Positioning System, the method is an excellent supplement to other positioning technologies. It is often used in sensor fusion setups as a complementary source. One of the reasons for the Kalman Filter's inaccuracy lies in naive radio coverage approximation techniques based on multivariate normal distributions assumed by previous studies. Therefore, in this paper, we evaluated those disadvantages and proposed a Gaussian mixtures model to address the non-arbitrary shape of the radio cells' coverage area. Having incorporated the Gaussian mixtures model into Switching Kalman Filter, we achieved better accuracy in positioning within the cellular network.

Mobile money, ICT, financial inclusion and growth: How different is Africa?

We investigate the contributions of fixed and mobile telecommunications (ICT) and mobile money to economic growth and financial inclusion in a 22-year panel of 146 countries. We extend the Solow growth model to include human capital, money, ICT, and mobile money, splitting the sample into sub-Saharan Africa (SSA) and the rest of the world (RoW) in addition to the whole sample analysis. We find mobile money affects economic growth through direct and indirect channels. Mobile money has a significant overall positive impact on growth, especially in countries with better mobile phone penetration and more dispersed populations. But its total quantitative effect is not large. Mobile money also tends to improve financial inclusion which in turn promotes growth. There are important differences between the SSA and RoW parameters, implying that the quantitative determinants of growth are different to some extent as between SSA and RoW.

Does mobile broadband use promote smallholder entrepreneurship? Evidence from rural China

ABSTRACT This study explored the impact of mobile broadband use on smallholders’ entrepreneurial engagement and willingness using data from a household survey collected from three provinces in China. We used an endogenous switching probit model to account for the potential selection bias associated with mobile broadband use. The empirical results indicated that mobile broadband use exerted positive and statistically significant impacts on smallholders’ entrepreneurial engagement and willingness. In particular, we found that mobile broadband use increased the probability of smallholders’ entrepreneurial engagement and willingness by 15.1 and 50.9% points, respectively. Further analysis revealed that the effects of mobile broadband use on smallholder entrepreneurship were heterogeneous across regions. Additionally, we found that while the impact of mobile broadband use on entrepreneurial engagement was the largest for smallholders with high income, its impact on entrepreneurial willingness appeared to be the greatest for smallholders with low income. This study extended the literature by analysing smallholder entrepreneurship and provided evidence on the effect of mobile ICT on smallholder entrepreneurship.

5G Is Out There: How to Ride the Market Storm and Thrive

We examine the changes in the commercial model adopted by the mobile ICT industry, due to the advent of 5G technology. This includes consideration of the challenges involved in rolling out a new infrastructure, which new markets this is likely to open up and how this affects partnering decisions. We show that as technology horizons expand, their degree of overlap increases and previously complimentary technologies may compete with each other, impacting the size of the addressable market. It is expected that 5G, whilst supporting its existing markets, will offer additional machine to machine, low latency and highly reliable services. We consider the synergies and the drivers for adoption for the wider 5G propositions and consider the impetus for more bandwidth and services and how the new technology impacts selling approaches. We identify the risks and uncertainties for the network providers and the likely requirements for a sustainable 5G business model and will describe our view of the steps necessary for a 5G successful outcome

An Extensive Study on Traditional-to-Recent Transformation on Face Recognition System

The face is the most visible biometric feature considered in manual and automated systems to identify individuals. In recent years, the inventions of low-cost high-resolution mobile cameras and surveillance systems have increased the usage and popularity of facial recognition systems. Today, various mobile apps, ICT systems, electronic devices, and cloud-based systems are using facial verification to gain access and authorization based security. Now, the facial recognition system has become a generalized authentication system instead of a specialized capability of specialized applications. This increasing scope and applications are reflected as the challenges and criticalities that exist in the real environment. The technological transformation was investigated by the researchers in image types, facial capturing, facial rectification, feature generation, and classification methods and techniques of face recognition systems. This paper has provided an extensive study on each stage of standard FRS (Face Recognition System). The methods and measures provided by researchers for improving and optimizing face normalization, segmentation, feature generation, and face recognition are provided in this paper. Each of the methods is also defined along with the performance, accuracy, and robustness against various addressed challenges. The paper has provided a map between the traditional and recent methods to explore the advancement in facial verification systems.

Technology-driven growth and inclusive growth- implications for sustainable development in Africa

The 21st century industrial and digital age has been largely driven by technological dynamics and advancement. The Neo-classical argued that beyond the classical notion of investments and capital accumulation, technology growth, which is driven by innovation and development is a major driver for growth and development. Africa economies, which has been largely described as technologically dependent, has over the years through technological diffusion engaged modern processes in driving its economic activities, which has informed economic and even social outcomes. Therefore, using the generalised methods of moments for selected sub-Saharan African economies, this study intends to assess the extent to which the presence of technology has informed economic activities in Africa as well as its impact in addressing developmental issues of poverty and unemployment. Also, given the current drive towards sustainability, this study takes the neo-classical growth theory a step higher by examining the modulating effects of technology-driven growth (through mobile densities and ICTs) in setting the pace for sustainable development in Africa. The study shows that the expected long-run impact of a technology-induced growth in reshaping developmental outcomes is seen from the estimates.

Knowledge Management by Women for Climate Change Adaptation in Agriculture

Bangladesh is one of the most vulnerable countries to climate change. Changes in rainfall pattern and intensity of extreme events are evident. Due to the male migration caused by climate change and development drive there occurs huge feminization in agriculture. The perception and impact of climate change is completely gender differentiated; women are seemed to be disproportionately affected by climate change. Moreover, to cope with the climate change the community is now cultivating new crops and varieties. Besides, they are using different new cultivation methods and techniques to adapt with climate change. For newly introduced crops the traditional knowledge is not sufficient. Use of mobile phones for knowledge and information sharing in agriculture is gaining popularity among farmers. Growing interest on climate change adaptive agriculture among the female farmers and easy availability of mobile phones and network service created an opportunity of knowledge management on adaptive agriculture. The mobile phone use efficiency and ICT self-efficacy among the rural women are significant. The decisionmaking capacity of women is limited and there are number of challenges though the farming responsibility is gradually shifting towards them. The study was conducted in the Charland of Nilphamari District of Bangladesh from June 2017 to December 2019 to know the scopes and requirements of adaptation knowledge management in agriculture.

The effects of using mobile technologies and ICT to students’ attitudes and achievement.

This study examines how enhanced media-devices is used in classrooms in Kazakh schools from the perspective of students, teachers, and decision makers. Based on four fundamental research questions, the goal is to analyze the level and impact of mobile technologies on pedagogy and students' perceptions of mobile technologies use in the classroom. Although some schools are afraid to introduce too much enhanced media-devices into their practice, this study aims to prove that introducing mobile technologies into the teaching and learning process is extremely valuable. Despite some innovations in pedagogical strategy, including notable advances in the use of mobile technologies, most secondary schools still have a long way to go as schools around the world still have an old, teacher-oriented paradigm, as opposed to more modern, student-centered approaches. These results indicate that the use of mobile technologies elicit positive responses from students both in terms of how they perceive the mobile activities and how it improved their performance.

First experiences with intraoperative CT in navigated sacroiliac (SI) instrumentation: An analysis of 25 cases and comparison with conventional intraoperative 2D and 3D imaging

BackgroundIntraoperative imaging is regularly used for intraoperative reduction control and evaluation of the implant position in trauma surgery. 2D imaging is limited, especially in complex anatomical regions such as the pelvis. The introduction of mobile 3D C-arms (CBCT: cone-beam computed tomography) has significantly improved intraoperative assessment. Nevertheless, there are still limitations regarding the field of view and metal artifacts. The purpose of this study was to evaluate the potential of intraoperative computed tomography (iCT) in surgical treatment of sacroiliac (SI) injuries. MethodsTwenty-five cases with injuries of the posterior pelvic ring involving the SI region that were surgically treated with navigated SI screws using the mobile iCT Airo (Brainlab, Munich, Germany) were analysed. Subsequently, the data were compared with historical control groups (CBCT with and without navigation; 2D fluoroscopy only). ResultsThe average score for subjective image quality achieved using the Likert scale is significantly higher for the iCT (4.48 ± 0.65) than for the CBCT (3.04 ± 0.69) with p = 0.00. The average duration of surgery using iCT was 189.32 ± 88.64 min, which was not significantly different from the control groups (p = 0.14 - 0.70). The average fluoroscopy time using iCT was 81.96 ± 97.34 s, which was significantly shorter than in all of the control groups (p = 0.00 - 0.03).The rate for postoperatively detected complications after using iCT was 0% (n = 0). Compared with the 2D-only control group (25%; n = 1), there is a significant difference (p = 0.01). The remaining two control groups showed no significant differences (p = 0.09 - 0.19). ConclusionsThe iCT provides excellent image quality that allows reliable assessment of fracture reduction and implant placement even in complex anatomical regions. The radiation exposure for the medical staff is reduced by decreasing the fluoroscopy time without significantly prolonging the surgical time. Overall, the possibility of intraoperative correction improves clinical outcome and patient treatment in the long term.

Mobile Work, Mobile Technology: Consequences for decision-making

This article explores how the decision-making processes that occur during mobile work differ from those that occur in fixed workplaces. We explored if the levels of intuition and rationality change in decision-making processes and how the use of mobile ICT influence the individual's perception of information quality. A qualitative research approach was applied combining a group and individual interviews, and a non-participant observation of a decision-making process simulation with 115 participants. The levels of intuition and reasoning in decision-making are not different between fixed and mobile groups. However, there is a perception of lower information quality and difficulties to process information in a mobility context. The time pressure caused by the constant connectivity via mobile devices has potentially adverse consequences for decision-making, increasing individuals' exposure to error. As positive consequences, there is greater agility of decision flows related to the use of mobile ICT, especially regarding low complexity decisions.

Investigation into post-adoption usage of mobile ICTs in Australian construction projects

PurposeWhile mobile Information and Communication Technologies (mobile ICTs) have been adopted by many construction organisations, research on the usage of mobile technologies in the context of construction project management has been scarce. Against this background, the purpose of this paper is to enhance the understanding of how Construction Management Professionals (CMPs) currently use mobile ICTs at work and the factors affecting their usage of mobile ICTs in the context of the Australian construction industry.Design/methodology/approachIn this research, the aim is addressed by a survey-based empirical research approach. A questionnaire was used to collect data about CMPs’ current mobile ICT usage and the factors affecting the usage. Then, relative importance index, factor analysis andχ2test were used to identify the most significant factors affecting their mobile ICT usage.FindingsThis research found that user characteristics such as age or years of experience are not the major factors affecting CMPs’ mobile ICT usage. The research also found that there are several barriers hindering an effective usage of mobile ICTs, namely work-family spillover, system quality issues, inconsistency in the way of using mobile ICTs among CMPs and the lack of organisational support.Originality/valueThe results of this research imply that to fully reap the potential benefits of mobile ICTs in construction projects, those barriers need to be addressed appropriately at the individual, organisational and industry levels. Also, this research informs construction organisations of how mobile ICTs can be deployed and used in the most cost-effective way in their projects.
