Predicting Cyberbullying Perpetration in US Elementary School Children.

Cyberbullying has emerged as a societal issue, and the majority of the research examining cyberbullying perpetration samples adolescent and/or emerging adult populations. A paucity of empirical attention has focused on young children (aged 8-10) regarding their cyberbullying frequency and predictors. The current study sampled 142 US youth aged 8-10 years and assessed their cyberbullying perpetration rate and cellular phone ownership. Results indicated that (a) older participants were more likely to cyberbully than their younger peers; (b) higher rates of cyberbullying were found for youth who already owned a cellular phone; and (c) an interaction between participant age and cellular phone ownership was found, suggesting that cyberbullying was highest for only the 10-year-old group who owned a cellular phone. These findings have implications for (a) parents, school administrators, health care providers, and anyone else interested in better understanding the predictors of cyberbullying perpetration; (b) intervention specialists focused on reducing cyberbullying in youth; and (c) a researcher interested in understanding the basic theoretical underpinnings of cyberbullying. Based on these findings, we recommend that (a) cyberbullying interventions be administered to youth as early as elementary school; (b) parents/guardians carefully consider the positive and negative consequences of youth cellular phone usage; and (c) increased communication between youth and parents/guardians concerning youth cellular phone activities.

Effect of information and communication technology and electricity consumption on green total factor productivity

Information and communication technology (ICT) supported by the Internet and mobile phone usage has become a significant factor influencing the intelligent development of the green economy in countries along the Belt and Road (hereafter referred to as B&R countries).Furthermore, electricity provides momentum for sustainable development. Therefore, this study examines whether ICT and electricity consumption affect green total factor productivity (GTFP).We explore the influence of Internet usage (INTER), mobile cellular phone usage (MOB),and electricity consumption (EPC) on GTFP in B&R countries from 2000 to 2021 using the dynamic panel system generalized method of moments (GMM) model. The results showed that MOB significantly inhibited GTFP, whereas INTER and EPC did not affect GTFP in lower-middle-income economies.In upper-middle-income economies, INTER and EPC inhibited GTFP, whereas MOB significantly promoted GTFP. Furthermore, INTER significantly promoted GTFP, MOB significantly inhibited GTFP, and EPC did not affect GTFP in high-income economies.The results based on EPC regulation showed that the interaction of ICT and EPC played a role in promoting GTFP in lower-middle-income economies.The opposite result was observed in upper-middle-income economies. Furthermore, the INTER and EPC interaction items promoted GTFP in high-income economies, whereas the MOB and EPC interaction items inhibited the GTFP.To improve the GTFP of the B&R countries, countries should improve ICT infrastructure and promote the efficiency of green energy use, so as to enable green development with ICT.

Financial Innovation and Restriction Hypothesis in the Banking Industry: Evidence from ASEAN- 5

This study investigates the financial innovation impact on bank market power in ASEAN banking from 2008 to 2018. It uses income diversification as a representative of financial innovation. The impact of countries’ development of financial innovation on market power is measured by the number of ATM, internet, and cellular phone users. The data panel regression model reveals that diversified banks may enjoy higher market power. This result rejects the banking restriction activity hypothesis, which states that a bank that diversifies its income stream results in increased competition. A higher number of available ATMs and more internet users lowers the percentage disparity of price and marginal cost and consequently increases the market competitiveness. Nevertheless, an increasing number of cellular users in the country increases market power. Conjecturally, more people use the online bank platform on their cellular phones, which creates a greater flow of fees to the bank.

Analysis of The Effect of Information and Communication Technology on the Production of Micro and Small Enterprises in Indonesia

At present, the Indonesian business world is still dominated by Micro and Small Enterprises (MSE). From the results of the 2016-Advanced Economic Census, the number of these businesses reached more than 26 million businesses or 98.68 percent of the total non-agricultural businesses in Indonesia. This business is also able to absorb more than 59 million workers or around 75.33 percent of the total non-agricultural workforce. The advantages of MSEs include generally producing consumer goods and services that are close to the needs of the community, not relying on imported raw materials and more utilizing local resources both in terms of human resources, capital, raw materials, and equipment, and using their own capital or not supported by loans. from the bank. On the other hand, the limitations of MSEs include the lack of access to banking, the ability and knowledge of human resources that are still low so that they are managed in a simple way, the use of limited technology, and has not been able to keep up with changing consumer tastes, especially those that are export-oriented. The rapid development of information and communication technology has an impact on changes in lifestyle, including consumption patterns and the way people sell and shop. The phenomenon of e-commerce provides an easy way to shop for people by not having to come directly to the store. This can be used by MSEs to reach larger consumers so as to increase their production and income. This study aims to analyze the effect of Information and Communication Technology on the production of Micro and Small Enterprises in Indonesia. This study uses panel data from 34 provinces in Indonesia between 2015-2020 which is estimated using the Generalized Method of Moments (GMM). The results show that capital, labor, computer users, fixed wireline users, cellular phone users, internet users and telecommunications expenses simultaneously have a positive and significant impact on the production of Micro and Small Enterprises in Indonesia. Partially, capital has a positive and significant effect on the production of Micro and Small Enterprises in Indonesia. On the other hand, telecommunications spending has a negative and insignificant effect on the production of Micro and Small Enterprises in Indonesia. While other variables have a positive and insignificant effect on economic growth in Indonesia. With these results, it is hoped that the government will issue policies to support micro and small businesses in increasing the use of information and communication technology to increase their production. Among other things, by building telecommunications infrastructure in areas that are not yet adequate, providing education to micro and small business actors in using information and communication technology, and providing light credit in the form of smartphones and computers to micro and small businesses so that they can be used to promote their products on the internet.

Synthesis of Longitudinal Human Location Sequences: Balancing Utility and Privacy

People’s location data are continuously tracked from various devices and sensors, enabling an ongoing analysis of sensitive information that can violate people’s privacy and reveal confidential information. Synthetic data have been used to generate representative location sequences yet to maintain the users’ privacy. Nonetheless, the privacy-accuracy tradeoff between these two measures has not been addressed systematically. In this article, we analyze the use of different synthetic data generation models for long location sequences, including extended short-term memory networks (LSTMs), Markov Chains (MC), and variable-order Markov models (VMMs). We employ different performance measures, such as data similarity and privacy, and discuss the inherent tradeoff. Furthermore, we introduce other measurements to quantify each of these measures. Based on the anonymous data of 300 thousand cellular-phone users, our work offers a road map for developing policies for synthetic data generation processes. We propose a framework for building data generation models and evaluating their effectiveness regarding those accuracy and privacy measures.

Evaluating package delivery crowdsourcing using location traces in different population densities

Crowdsourcing package delivery is an emerging business activity that utilizes people's existing travel for delivering packages and mail. While crowdsourcing can address the growing need for faster and cheaper package delivery without deploying the system, it is unclear which types of local crowdsourcing can be effective and perform in urban, suburban, and rural areas. This study suggests a method for simulating package delivery architectures using anonymized mobile location traces, comparing prominent architectures, and elevating the success rates, duration periods, and other measures in different geographical locales. Based on a sample of 1.8 million cellular phone users in Israel, we show that both systems have performance challenges in areas with low population density. Our analysis also indicates that multi-hop architectures allow couriers to transfer packages to their destination by leaving them at intermediate stop points until the next courier picks them up, outperforming one-hop architectures, in which packets can be transferred between origin and destination stop points by one courier. We conclude the paper by discussing how mobility-based simulation methods can be used to assess the performance of mobile crowdsourcing systems before they are built.

Formative Assessment to Improve Cancer Screenings in American Indian Men: Native Patient Navigator and mHealth Texting.

Cancer screening rates among American Indian men remain low, without programs specifically designed for men. This paper describes the Community-Based Participatory Research processes and assessment of cancer screening behavior and the appropriateness of the mHealth approach for Hopi men’s promotion of cancer screenings. This Community-Based Participatory Research included a partnership with H.O.P.I. (Hopi Office of Prevention and Intervention) Cancer Support Services and the Hopi Community Advisory Committee. Cellular phone usage was assessed among male participants in a wellness program utilizing text messaging. Community surveys were conducted with Hopi men (50 years of age or older). The survey revealed colorectal cancer screening rate increased from 51% in 2012 to 71% in 2018, while prostate cancer screening rate had not changed (35% in 2012 and 37% in 2018). Past cancer screening was associated with having additional cancer screening. A cellular phone was commonly used by Hopi men, but not for healthcare or wellness. Cellular phone ownership increased odds of prostate cancer screening in the unadjusted model (OR 9.00, 95% CI: 1.11–73.07), but not in the adjusted model. Cellular phones may be applied for health promotion among Hopi men, but use of cellular phones to improve cancer screening participation needs further investigation.

DETERMINANTS OF CUSTOMER RETENTION IN CELLULAR INDUSTRY OF BANGLADESH: A STUDY ON YOUNG CUSTOMERS

The telecommunication industry in Bangladesh, with the global trends, has been considerably grown up during the last two decades. At the end of December 2020, the number of cellular phone subscribers reached 170.137 million under four operators in the country. The telecommunication industry has been experiencing increased competition because the government has introduced uniform call rates for all operators and launched mobile number portability (MNP) in 2018, resulting in an easy switching for a customer to other operators. This situation has originated a great challenge for the cellular service providers in Bangladesh to retain the existing customers, especially the young subscribers who have more switching trends. The hyper-competition in the industry also induced mobile operators to work hard to attract new customers and retain the existing ones. The paper, therefore, aims to find out the determinants of young customer retention in the cellular industry of Bangladesh. This study is exploratory based on primary data collected from 415 young cellular phone users of the age of below 40 years in the two largest cities (Dhaka and Chittagong) in Bangladesh. The study examined eight determining factors of customer retention using the statistical tools: mean and standard deviation. The study found that price perception, customer satisfaction, switching barriers, and brand image are the strongest customer retention determinants. This study's findings have important implications for cellular phone operators to tailor their services and strategic priorities for maximizing customer satisfaction, loyalty, and retention to gain market growth and higher returns.

Examining the behavioral intentions of tourism destination communities

This study aims to explain the behavior of tourist destinations communities toward the Smart Rural Tourism Information System (SRTIS). It reveals through their intentional behavior where the technological environment mediates the relation with their behavior to deliver the information. For this reason, we surveyed selected tourism destinations, where the respondent represented by various community groups. The approach used Planned Behavior Theory to explain behavioral intention. Using the PLS application, we found that the technological environment affects the behavioral intention to convey tourist information. Furthermore, the intention to convey affects conveying information in SRTIS. The research results showed that various tourist destination communities are ready to share information in each destination. The technology environment supports it, communities' cellular phone usage, as a mediation. So, encouraging communities to provide information in the system built will keep the destination sustainable. Hence, we suggest that the local government empower communities to consider more tourism resources and promote them.

ASEAN Economic Community and its impacts: Opportunities, challenges, and implications for higher education

The vision of the ASEAN Economic Community (AEC) envisaged as a global ASEAN has impacts on all sectors, including higher education (HE), a key driver to the goal. However, it is still debatable whether HE can achieve it. This study aimed to draw insights into its impacts with a focus on opportunities, challenges, and implications for HE. This study employed qualitative, comparative, interpretive, and in-depth analysis of documents. The findings revealed that the progress of AEC has a great impact on HE in three areas. Prospective opportunities comprise the services sector and internal cooperation and collaboration. The sector accounted for approximately 50% of the real output in 2018. The top three countries were Singapore (68.9%), Thailand (59.9%), and the Philippines (57.8%). However, a crucial challenge is an inequitable access to digital-driven education due to inequitable access to the Internet among member countries. The gaps of subscribers and cellular phones lie between 94.6 and 33.1 and between 180.2 and 51.9 respectively. Singapore, the regions’ best education and labor mobility destination, has the highest rates of subscribers (100) and cellular phone usage (88.2). For implications, policymakers should foster interconnectivity and digitalization through innovation-driven education. A feasible roadmap for strategic management is also proposed for AEC engagement.

The Hazards of Radiation of Telecommunication Mast on Male Rabbits Reproductive Parameters

Background: There has been growing public concern on the effects of electromagnetic radiation (EMR) attributed to new technologies such as telecommunication which produced radiation for cellular phones on human health. Many studies have recently been published on this topic. However, possible consequences of the cellular phone usage on human reproductive parameters have not been investigated adequately. Aim of the work: This work was carried out to evaluate the effects of telecommunication mast (TM) radiation exposure on some reproductive parameters of male rabbits. Materials and methods: Twenty-five (25) male rabbits with an average weight of 600g-1,270g were divided into 5 groups, (n=5), with consideration towards size variation. Group E was served as the control while groups A, B, C and D were the treated groups placed at a distance measured in feet (ft) (0, 5, 10, and 15ft) around a telecommunication mast (TM). Group A (0 ft) was directly under the mast and Group D (15ft away) was the farthest from the mast while the group E (Control) was kept away from the vicinity of the mast. On the last day of 54th day of exposure to the mast tower, the rabbits were weighed and thereafter slaughtered by the use of chloroform as a sedative. The testes were removed for histomorphometric and histologic studies (using Hematoxylin and Eosin staining techniques) and semen was also collected from their epididymides for sperm examination. Results: Degenerative changes were observed in testes in the form of testicular atrophy which is primarily associated with shrinkage of the seminiferous tubules and loss of sperm cells and widening of the interstitial space with a mild shrinkage of the interstitial cells. A significant decline in the number of sperm cell count of the most exposed groups and a significant increase in the number of dead cell and non-motile cell. Moreover, histomorphometric analysis of the seminiferous was investigated and a significant reduced value of the seminiferous cross sectional area (CSA) was observed. Meanwhile, the mean value for the seminiferous luminal diameter (LD) in the most exposed group was significantly increased and value of the seminiferous epithelia height (GEH) in the most exposed and the adjacent groups were significantly increased. Where as seminiferous tubule diameters (STD) of the exposed rabbits in all the groups were insignificantly decreased. Therefore, the result is distance-dependent from the most distanced group down to nearest group to the mast. Conclusions: The results of this study showed that long-term exposure of radiation from telecommunication mast resulted in damage to male rabbit reproductive parameters, therefore establishes that there are reproductive health implications of exposure to mast radiation and minimizing this exposure will go a long way to improve healthy living.

An Iterative Power Regulation Technique in Emergency Cognitive Radio Network Based on Firefly Algorithm

Background: Manmade disasters like explosion, toxic wastes, chemical spills etc. have become an imperative concern for our society. Manmade disasters are not everyday phenomenon. Thus, the allocation of separate resources is not realistic. The idea is to use existing cellular infrastructure to implement single hop cognitive radio sensor network for protecting human being from manmade disasters. Objective: The main objectives of this paper are as follows: (a) design of an efficient iterative power regulation algorithm based on the Firefly Algorithm for the proposed network, (b) computation of sensor nodes’ optimal power for different position of the cellular user from the base station assuming that cellular user compromises power for its own sensor node, (c) computation of the maximum number of sensor nodes coupled with single cellular user for different distances from the base station in worst channel condition, and (d) comparative performance analysis with state-of-the-art algorithms. Method: In the presence of explosive and toxic gases, cognitive radio in sensor node establishes a connection with the nearest base station to send pre-disaster alert signal utilizing cellular user’s resources. The power is distributed among sensor nodes maintaining the fundamental requirements of cellular users. Here, an iterative power regulation mechanism is employed for distributing the power between sensor node and cellular user to achieve reliable utility of the network. The fitness function is designed under the constraints of interference and the designed algorithm is implemented in MATLAB platform towards the search of optimal power of sensor nodes by maximizing the fitness function. Results: Comparative performance analysis demonstrates the effectiveness of the proposed algorithm in terms of speed of convergence, the position of mobile phone user from the base station, number of coupled sensor nodes with single cellular user, and Jain’s fairness factor. Conclusion: The proposed network controls the occurrence of manmade disasters and achieves reliable transmission of emergency information prior to disaster without disrupting cellular phone users. Simulation results validate that the proposed IPRFA algorithm outperforms with respect to state-ofthe- art methods in terms of sharing power and Jain’s fairness factor.

Comparative Study the Effect of Antenna Selection on Capacity and Energy Efficiency of 5G Systems

As a result of the rapid growth in wireless communications and the increase in the number of users of cellular phones around the world, massive multi-output, and multi-input (massive MIMO) systems have been used. The main drawback of such a system is the increase in the number of antennas and the amount of energy consumed. To mitigate that the number of active antennas can be reduced to save some energy. In this paper, we will study different algorithms for choosing the suitable antennas in MIMO systems, subject to keeping an acceptable level of bit rate and energy efficiency in the system. The study will also consider the amount of complexity for each algorithm based on the consumed time to perform each algorithm in MATLAB.

Observation of Human Brainwave Signals Due to Mobile Phone Usage

There is ongoing discussion whether the cellular or mobile phone usage causes any health effects. The aim of this research is to investigate the effects of mobile phone usage on human brainwaves using electroencephalograph (EEG). The brainwave signals were analyzed using Statistical Package for the Social Sciences (SPSS). Thirty samples were interviewed prior to EEG recording. Then, the EEG recordings were performed for three sessions; before, during and after the phone calls. The findings show that alpha is dominant compared to the other frequency bands. In addition, value for the left brainwaves always higher than the right for all frequency bands which means that the samples were left brain dominant. The overall correlation between left and right brainwaves signal for all bands shows decrement for during and after phone calls, thus reducing brainwaves balancing. Therefore, there is evidence that the usage of mobile phones affect the brainwaves.

Mobile Phone Keeping Behavior among Working Women

Background: Recent alarming increase in breast cancer, especially in younger women, has been attributedto the increasing usage of mobile cellular phones and their placement in contact with the body especially thebreast region. The bio-effects of high frequency electromagnetic radiations accompanied by thermal damageto the tissues play an important role in tumor initiation and progression.Method: The study was carried out in 260 working women from Pondicherry. They were questioned aboutmobile phone keeping behavior using a three item questionnaire.Results: Women involved in unskilled job kept their mobile phones more proximal to the breast regionwhen compared to the women engaged in white collar job. However the duration of mobile phone usagewas higher in the latter group.Conclusion: Longitudinal studies to follow up the relationship between mobile phone keeping behavior anddevelopment of breast cancer need to be undertaken. Hence we propose researchers to ask for history aboutmobile phone keeping behavior while dealing with breast cancer patients.

Academic Entitlement Predicts Smartphone Usage during Class

In the present study, we examined the relationship between academic entitlement, nomophobia, and cellular phone usage during class. Students reported the amount of time spent on their phones during class, frequency of checking phones during class, academic entitlement, and dimensions of nomophobia (cell phone addiction). Academic entitlement and some dimensions of nomophobia were positively correlated with cellular phone usage. However, only academic entitlement uniquely predicted phone usage during class above and beyond nomophobia. The results suggest that academic entitlement is a uniquely important factor in predicting cellular phone use during class.
