The telecom industry is a typical oligopolistic industry, so telecom carriers are easy to conspire in the course of operation. This article analyzes the influence of product quality differentiation on telecom carrier collusion by constructing a game model. The results show that the critical discount factor that keeps telecom carriers persisting in collusion increases with the decrease of product quality differentiation, that is, the smaller the product quality differentiation is, the harder it is for telecom carriers to adhere to long-term collusion. Conversely, the greater the product quality differentiation is, the greater the risk of a large number of users leaving the network can be when telecom carriers betray the collusion, so they will not easily betray it. Therefore, the product quality differentiation is conducive to the realization and maintenance of telecom carrier collusion. At the same time, telecom carriers that provide different quality products have different incentives for collusion, among which those providing low-quality products are more likely to persist in collusion. What is more, this article also finds that China's telecom industry has great product quality differentiation in the full-service operation, so when telecom carriers pursue the differentiation development of product quality, the government should take corresponding measures to prevent their collusion.

Mobile payment has many advantages, such as convenience, attracting more and more people to use. Mobile payment market is vast, containing huge profit and chance. Besides banks, telecom carriers and third-party payment companies are chasing this market, they all want to earn more money in this market. They all compete and cooperate with each other. In the process of game, the government play an important role in it. This paper mainly studies the game between telecom carriers and third-party payment companies, through building the static game model of perfect information, then we analyze the model Nash equilibrium comprehensively. At last, considering the actual situation, we get the main factors of the model which affect Nash equilibrium and choose which operation model the two sides will take. Keywords: Telecom carrier, Nash equilibrium, Third party payment company, Game.

China's recent economic growth has expanded industrialization and urbanization, upgraded consumption, increased social mobility, and initiated a shift from an agricultural-based economy to one based on services and industry. However, more than half of China's population still lives in rural areas, where the average per capital income is less than a third of the urban average. The government of China has increased its commitment to rural development and poverty-reduction programs, with attention to narrowing the rural-urban divide. Informatization—defined as the transformation of an economy and society driven by information and communications technology (ICT)—is increasingly being explored as a way of helping poor people. Rural Informatization in China presents an overview and in-depth analysis of rural ICT initiatives in China. This study reviews the present-day status of China's rural informatization infrastructure, examines and summarizes by organizational model the key initiatives in the past decade, and provides policy recommendations to address current challenges. Case studies of different financing models of rural ICT initiatives from China and other countries are included.

In today's digital age, most individuals own smartphones and routinely use telecom services. As a result, understanding users' intentions to continue using specific mobile carriers based on their experiences becomes paramount for corporate sustainability. This study delves into the intricate dynamics of user experiences, aiming to elucidate the primary factors influencing continuance intention. By incorporating a unique theoretical framework that emphasizes customer experiences, this research seeks to bridge a gap in the current literature. Drawing from a sample size of 299 smartphone users who have active subscriptions with telecom services, we employed partial least squares structural equation modeling (PLS-SEM) to rigorously analyze the data. Our findings indicate a significant relationship where the corporate image is influenced by factors such as contract terms, perceived fees, call quality, and call center experience. Moreover, user satisfaction, another pivotal variable, is shaped by the same factors. Both corporate image and user satisfaction were found to be determinants of a user's continuance intention. The distinguishing value of this research lies in its holistic approach to user experience, uniquely integrating various service touchpoints to provide comprehensive insights into user intentions in the telecom domain.

We present an experimental study on the optical quality of InAs/InP quantum dots (QDs). Investigated structures have application relevance due to emission in the 3rd telecommunication window. The nanostructures are grown by ripening-assisted molecular beam epitaxy. This leads to their unique properties, i.e., low spatial density and in-plane shape symmetry. These are advantageous for non-classical light generation for quantum technologies applications. As a measure of the internal quantum efficiency, the discrepancy between calculated and experimentally determined photon extraction efficiency is used. The investigated nanostructures exhibit close to ideal emission efficiency proving their high structural quality. The thermal stability of emission is investigated by means of microphotoluminescence. This allows to determine the maximal operation temperature of the device and reveal the main emission quenching channels. Emission quenching is predominantly caused by the transition of holes and electrons to higher QD’s levels. Additionally, these carriers could further leave the confinement potential via the dense ladder of QD states. Single QD emission is observed up to temperatures of about 100 K, comparable to the best results obtained for epitaxial QDs in this spectral range. The fundamental limit for the emission rate is the excitation radiative lifetime, which spreads from below 0.5 to almost 1.9 ns (GHz operation) without any clear spectral dispersion. Furthermore, carrier dynamics is also determined using time-correlated single-photon counting.

We present a detailed theoretical and numerical study on the temperature-tunable plasmonic and optical behavior of CdS@ITO core-shell quantum dots (CSQDs) embedded in dielectric environments. Utilizing the quasi-static approximation and a thermally adaptive Maxwell-Garnett effective medium approach, we systematically analyze how thermal variation modulates key performance metrics, including localized surface plasmon resonance (LSPR), local field enhancement factor (LFEF), refractive index dispersion, extinction coefficient (), and resonance quality factor (Q). Thermal effects are incorporated via a modified Drude model accounting for temperature-dependent carrier density and damping rate in the ITO shell. Simulations reveal LSPR redshifts of over 100 nm with increasing temperature, accompanied by a monotonic decline in LFEF from above 1500 to below 100 across 300–600 K. Quality factors degrade from at room temperature to at 600 K due to increased electron–phonon scattering. Spectral tunability in the 1300–1550 nm telecom range is demonstrated, with extinction coefficients maintained below 0.06. These results highlight the potential of CdS@ITO CSQDs as thermally responsive, low-loss components for thermally adaptive photonic systems, including nanoscale optical buffers, modulators, and slow-light devices.Highlights• Demonstrate thermal tuning of plasmonic resonances (1300-1550 nm) for adaptive photonicdevices.• Maintain strong field enhancement and low optical losses up to 600 K, providing a CMOScompatiblealternative to gold and silver.• Enable tunable slow-light effects and improved thermal stability via geometric optimizationof ITO shells.

Purpose - The purpose of this study is to investigate the impact of some organizational culture attributes, including: openness to change, innovation, trust, teamwork, morale, information flow, employees' involvement, supervision, customer service and reward orientation on the knowledge exchange (KE) process within the context of the Saudi Telecom Company (STC) as a representation of the Saudi context.Design methodology approach - A descriptive correlation design was used. A web survey was used to collect data from 378 employees working on STC using Random Number Generator 0.2 software. The sample was selected using an e-mailing list.Findings - The findings revealed that the cultural attributes of trust, innovation, information flow, supervision, and reward have an impact on KE within the context of the STC. Additionally, the study revealed a statistically significant correlation between organizational culture and KE as a whole (0.75), which emphasizes the effective role of organizational culture factors on exchanging knowledge within the context of the study.Research limitations implications - This study presents only preliminary results from limited data. Additional quantitative data are needed to employ more superior statistical analysis. Moreover, the current study is exploratory in nature with a relatively small number of respondents from the STC.Originality value - The originality of this study is derived from the importance of KM as a strategic organizational tool as well as the importance of culture as an influential factor. The STC, one of the biggest companies in the Middle East, is trying to implement aspects of KM. Towards this end, the company has created a new division of KM which is suffering from a lack of research studies that explore issues relating to KM in Arab countries in general and the Saudi context in particular, which makes the topic of this research not only unique but also of high practical significance.

The debacle of the telecommunications industry at the turn of the millennium resulted in significant consequences for investors, workers, financial institutions, telecom companies, and the economy in general worldwide. In the midst of the telecom bubble, the CLECs (competitive local exchange carriers) adopted similar or identical business plans and saturated the market, which resulted in destructive competition. In this study, we investigate the isomorphic business models of the CLECs from the perspectives of the new institutional theory. We argue that the combined coercive, mimetic, and normative institutional forces exerted on the companies by the actors who controlled the funding, managed the business, and provided the information fashioned the isomorphic CLEC business models, which in turn contributed to the demise of these companies and thus the burst of the telecom bubble. Evidence of the institutional influences on CLECs and the actors exerted the influences are presented and their consequences are discussed. [PUBLICATION ABSTRACT]
