Kilkari is an outbound service that makes weekly, stage-based, prerecorded calls about reproductive, maternal, neonatal and child health directly to families’ mobile phones, starting from the second trimester of pregnancy and until the child is 1 year old. Since its initiation in 2012–2013, Kilkari has scaled to 13 states across India. In this analysis article, we explored the subscriber’s journey from entry to programme to engagement with calls. Data sources included call data records and household survey data from the 2015 National Family Health Survey. In 2018, of the 13.6 million records received by MOTECH, the technology platform that powers Kilkari, 9.5 million (~70%) were rejected and 4.1 million new subscribers were created. Overall, 21% of pregnant women across 13 states were covered by the programme in 2018, with West Bengal and Himachal Pradesh reaching a coverage of over 50%. Among new subscriptions in 2018, 63% were subscribed during pregnancy and 37% after childbirth. Of these, over 80% were ever reached by Kilkari calls and 39% retained in the programme. The main causes for deactivation of subscribers from the system were low listenership and calls going unanswered for six continuous weeks. Globally, Kilkari is the largest maternal mobile messaging programme of its kind in terms of number of subscribers but the coverage among pregnant women remains low. While call reach appears to be on the higher side, subscriber retention is low; this highlights broader challenges with providing mobile health services at scale across India.

In 2018, India had 1.2 billion subscribers, and it was the second largest telecommunications market in the world. The industry had witnessed the emergence, ascendency, and dominance of private sector players during the last two decades. The telecom sector was characterized by a growing wireless user base and Internet subscriber base. The dwindling average revenue per user (ARPU) in the mobile telephony segment and the declining average cost to subscriber per GB of data were manifestations of the intense rivalry in the sector which had led to price wars among incumbent players. The Supreme Court of India’s judgement on Adjusted Gross Revenue (AGR) in October 2019 obligated the industry players to pay ₹1,470 billion as payment towards their licence fee and spectrum usage charges. Vodafone Idea and Bharti Airtel, two leading players, collectively owed 60% of the aforementioned liability. Declining revenue had already squeezed the profitability and liquidity of these companies. The AGR liability augmented their challenges.

Bike share programs are becoming increasingly popular across U.S. cities. However, their impact on persistent disparities in cycling by gender, race, and socioeconomic status remains understudied. We examined whether subscribers of Citi Bike, New York City’s (NYC) largest bike share program, reflect the sociodemographic profile of NYC cyclists. Using NYC Community Health Survey data, we described adult NYC residents of neighborhoods with ≥1 Citi Bike stations who rode a bicycle at least once a month. Citi Bike members were also described using first-time subscriber survey data. We compared the sociodemographic characteristics of these groups via a z-score with pooled variance. Approximately 2.2 million residents lived in 15 NYC neighborhoods with ≥1 Citi Bike station, and 449,000 (20.5%) reported cycling at least once a month in the past 12 months. Among first-time Citi Bike subscribers, 23,223 (11.5%) completed the survey. Compared with NYC cyclists, Citi Bike subscribers were more likely to be women, aged 24 to 45, White, college graduates, and from a household with an income >400% than the poverty level. Compared with the general population, cyclists were more likely to be White, male, and from a household with an income >400% than the poverty level. Race/ethnicity and socioeconomic status (not gender) disparities were larger among Citi Bike subscribers than NYC cyclists. With the emergence of cycling as an alternative transportation during the COVID-19 pandemic and the extension of bike share programs, this highlights the need for ongoing, systematic monitoring of bike share user socioeconomic characteristics to evaluate equitable use and access.

Various streaming entertainment platforms, or often referred to as SVOD, have become entertainment for Indonesian viewers, shifting television as their daily entertainment channel. However, research that raises this issue is still very rare, especially in looking at how the viewers and subscribers of these various streaming services are. This paper aims to see, firstly, how entertainment streaming subscribers respond to this development, and secondly, how streaming subscribers negotiate local Indonesian shows on these various SVOD channels. The research was conducted by distributing questionnaires filled out by 264 respondents and then followed by qualitative interviews through FGDs with 25 participants who identified themselves as heavy viewers. Research shows that Netflix is still the most-subscribed streaming channel, although many also subscribe to it illegally. Regarding local content, participants expect Netflix to imitate similar streaming channels by producing works by local Indonesian directors, not just as a distribution channel. Indonesia as the largest streaming subscribers in Asia deserve recognition not only in terms of audienceship, but also in terms of auteurship by producing netflix originals by Indonesian filmmakers.

Testo completoAbstract (sommario):
The Nigerian Telecommunications Industry is classified as the fastest-growing and most competitive Telecommunications industry in the world. It has the largest subscriber base in Africa with over 150 million subscribers. Due to the increased competitiveness in the telecommunication industry in Nigeria, customer retention has become the focus of telecommunication providers. It is in this light that this paper is built. Hence, the general objective of the paper is to determine the effect of experience marketing on customer retention in the Nigerian Telecommunications industry. The study made use of primary data gotten through a validated set of structured questionnaires which was distributed to a selected sample of 402 respondents within the six states of the south-south geo-political zone of the Niger Delta Area of Nigeria, which are Akwa-Ibom, Bayelsa, Calabar, Edo, Delta and River States. The paper adopted correlation and regression analysis to test the formulated research questions and hypotheses. After the analysis, it was discovered that there was a strong and positive effect of experience marketing on customer retention in the Nigerian Telecommunications industry. The study, therefore, concluded that Customer Service Quality, Customer Brand Relationship, and Customer Emotional Experience are good indicators and dimensions of Experience Marketing that could increase the degree to which customer retention is enhanced in Telecommunication Firms in Nigeria. Hence, it was recommended, among others, that Telecommunication operators in Nigeria must switch from the traditional marketing approach to an experience-based marketing strategy if they want to remain relevant and competitive in the globalised telecommunication industry.

Abstract Java Madura Bali (Jamali) system is the Indonesian largest grid, which contributes approximately 61%, with the Coal Thermal dominates by 59% and followed by the New Renewable Energy (NRE) of 9%. Solar Photovoltaic Power Plants (SPP) contribute only 1% from the NRE itself. Low voltage customers (TR) are approximately 61% with the residential contribute approximately 42%. The rates of the national SAIDI is 12.72 hours/subscriber/year and the national SAIFI is 9.25 times per subscriber/year. There is some challenge in regulating voltage in area with high penetration of solar PV, case of voltage fluctuation in response to the fluctuating of solar irradiance, as well as other factors such as load transient. This voltage fluctuation is proportional to the amount of current generated by the PV system and also proportional to the solar irradiance. Hydrogen energy storage (HES) is an alternative to NRE-based energy storage technology. Integrating solar PV with hydrogen energy storage and optimisation device may mitigate PV-driven voltage fluctuation, preventing excessive reserve power flow on the grid. The hydrogen energy storage system can cover variation of the loads at the nearby solar PV system in the microgrid and the ability to manage those loads, as mentioned in the energy management system. Integrating the HES within Solar PV system can improve the curve shape, improve system reliability and voltage stability, especially in the Residential Microgrid. Also may build the opportunities to earn new revenues from wholesale electricity markets, enhancing the reliability rate and competitive monetary value.

The Indian telecom market is the second-largest telecommunication market in the world. The market is fiercely competitive due to the rising subscriber base and increasing demand for network connectivity. The present study tries to analyze the strategies and policies that determine the survival of the mobile telecom operators of India. The focus is also on the benefits and drawbacks of various factors that eventually lead to the success or failure of these companies. The study is based on an exploratory research method where 30 doctoral theses have been reviewed, and secondary sources, namely valuable reports, and websites, have been referred to. Gleaned from the literature review, it is found that with efficient policy-making, the Indian telecom industry deliberated on infrastructural support, technological advancement, and industrial development. The success of an organization depends not only on effective telecom policy structure but also on customer loyalty, customer retention, marketing mix, service quality, and corporate image of the telecom operators. All these factors positively influenced customer perception and satisfaction and motivated customers’ buying decision to have a competitive edge in the telecom market.

Testo completoAbstract (sommario):
Along with the global telecom sector, the Indian telecom market has evolved over the past three decades. From the first generation technology in the 1990s, the telecom industry in India offered 4G services in 2012. From microwave technology it has moved into underground fibre optic cables, enhancing the quality and variety of telecom services. Ahead of several emerging markets, subscriber demand in India shifted to data from voice telephony. Subscriber base grew substantially, but average revenue per user (ARPU) has fallen significantly. Intense competition has led to consolidation in the industry. The mobile services faced market disruption from Reliance Jio (R-Jio). The latter launched a strategy of predatory pricing resulting in data wars. R-Jio’s network was based on 4G technology, while other competitors were still offering 2G- and 3G-based services. In comparison to competitors, R-Jio laid more fibre optic cables. Therefore, it could effortlessly upgrade the services offerings to 5G and other future technologies, which competitors could not match so they experienced fall in profits or outright losses. R-Jio also moved into providing fibre-to-the-home technology accompanied with ultra-high-speed internet that could provide a host of entertainment features. As a virtual knee-jerk reaction to the severity of the competitive challenge facing it, Vodafone initiated merger talks with Idea Cellular and soon achieved its culmination. This merger resulted in the largest telecom service company in India. However, Vodafone Idea Ltd.’s balance sheet was over leveraged, rendering it incapable of playing the price cutting game. Besides, it was unclear if it would be able to build the formidable infrastructure required to invest in 5G spectrum, offer superior content as well as smart devices. It soon became obvious that the merger could catapult Vodafone to the pole position in the industry but staying and flourishing there would require it to be more resourceful, imaginative and aggressive. Balesh Sharma, the CEO of Vodafone-Idea Ltd., and his top management team had to respond to the challenges the company was facing and emerge successful.

Organizational performance monitoring and management are crucial in today’s fast-paced corporate world. Performance metrics show how much an organization improves. The study’s objective was to quantify the non-financial performance metrics (NPMs) in the telecommunication business performance from the customers’ perspective. The method of quantitative research and standardized questionnaire was used to obtain primary data from Nepal’s renowned and the largest telecommunication corporation cell phone subscriber. The questionnaire contained three general demographics-related inquiries and 32 non-financial performance metrics on a 6-point Likert-type scale. The study gathered a total of 389 responses using a convenience sampling technique. The findings revealed that non-financial performance metrics contributed to around 54% of the success and capabilities of Nepalese telecommunications enterprises. The study resulted in the development of a reliable and valid instrument for measuring the performance of the emerging market for telecommunications services using non-financial performance criteria. The study confirmed Adhikari and Chalise’s (2021) conclusions that the Nepalese telecommunication industry’s performance assessment has been a significant managerial instrument, evolving to reflect strategic aims by including non-financial performance criteria. Non-financial performance measurements help the company integrate its business performance with its strategy, enhancing market success.

Testo completoAbstract (sommario):
This work focuses on publish/subscribe systems, where producers publish information and consumers express their interests for certain types of information. The data is disseminated according to its nature and the interests of the consumers. Publish/subscribe systems have become a hot research topic, because the strong decoupling that they offer between the participants makes them well adapted to large scale distributed information systems. We first present a publish/subscribe system that we specifically designed to implement efficient and reliable distribution of structured xml content to very large populations of consumers. For that purpose, our system integrates several novel technologies, such as subscription aggregation. We have analyzed its efficiency by the means of various simulations and, to experiment with the conditions of the real internet, we have performed a large scale deployment in the planetlab testbed. Experimental results demonstrate that our system offers very good performance and salability under normal operation and can quickly recover from system failures. We then present a novel approach to building a publish/subscribe system based on the peer-to-peer paradigm. Our system features an extremely simple routing process. The price to pay for this simplicity is that routing may not be perfectly accurate. However, by organizing the peers in "semantic communities'', i. E. , by organizing them according to their interests with adequate proximity metrics, we can minimize the routing inaccuracy. Experimental results demonstrate that the routing process is indeed very accurate and highly efficient in the presence of large consumer populationsCette these est consacree a l'etude de reseaux de type publication/abonnement dans lesquels des producteurs publient de l'information a l'intention de consommateurs. Les donnees sont diffusees selectivement en fonction de leur nature et des interets des consommateurs. Les reseaux de ce type sont devenus un theme de recherche tres populaire car ils offrent un grand decouplage entre les elements du systeme, permettant de passer aisement a l'echelle. Dans un premier temps, nous presentons un systeme de type publication/abonnement que nous avons specialement concu pour la diffusion efficace et fiable de documents xml a large echelle. Notre systeme integre plusieurs technologies et algorithmes novateurs, tels que l'agregation de souscriptions. Nous avons realise de nombreuses simulations et nous avons deploye notre systeme sur la plate-forme experimentale mondiale planetlab. Les resultats montrent que notre systeme est efficace et passe aisement a l'echelle, et est capable de se reconstituer rapidement suite a des pannes de liens ou de routeurs. Dans un deuxieme temps, nous proposons une approche originale pour concevoir un systeme de type publication/abonnement. Notre systeme est base sur le concept pair-a-pair. La principale innovation est l'utilisation d'un protocole de routage extremement simple. Il en resulte une certaine perte de precision, que nous pouvons cependant minimiser en organisant les pairs en fonction de leurs interets dans des ''communautes semantiques'', au moyen de metriques de proximite adequates. L'evaluation experimentale montre que le routage est effectivement precis et tres efficace en presence de grandes populations de consommateurs

This thesis presents the design and evaluation of content-based publish/subscribe systems for efficient content dissemination and sharing of dynamic and large-scale networked applications. The rapid development of network technologies and the continuous investment in network infrastructure have realized a ubiquitous platform for sharing information. However, there lacks efficient protocol and software that can utilize such resource to support novel networked applications. In this thesis, we explore the possibility of content-based publish/subscribe as an efficient communication substrate for dynamic and large-scale networked applications. Although content-based publish/subscribe has been used extensively in many small-to-medium scale systems, there is no Internet-scale applications that utilize this technology. The research reported in this thesis investigates the technical challenges and their solutions of applying content-based publish/subscribe in various applications in mobile networks and Internet. We apply content-based publish/subscribe in the interest-driven information sharing for smartphone networks. We design efficient approximate content matching algorithms and data structures. We study how to construct optimal overlay publish/subscribe overlay networks. We propose architecture designs that make Internet content-based publish/subscribe robust. We also design a name resolution system that enables content discovery in the Internet. These techniques are evaluated comprehensively in realistic simulation studies, and some of them are further evaluated on PlanetLab testbed with prototype implementations.

Testo completoAbstract (sommario):
La particularité des systèmes xDSL (Digital Subscriber Line) et CPL (Courants Porteurs en ligne) est de réutiliser des supports de transmission existants, à savoir l'infrastructure téléphonique et le réseau électrique domestique. Ces deux techniques présentent ainsi l'avantage d'optimiser l'utilisation de ces media de communication. Néanmoins les supports filaires utilisés n'étaient pas initialement destinés à la transmission d'informations à haut débit et des problèmes de Compatibilité Electromagnétique (CEM) se posent inévitablement. Dans ce contexte, ce travail de thèse étudie les problèmes de CEM dans les réseaux filaires supports des hauts débits, à partir des caractéristiques physiques des supports de transmission. Des solutions innovantes sont proposées pour la réduction de la diaphonie dans les réseaux téléphoniques multifilaires transportant les signaux xDSL; puis pour l'amélioration de la fonction de transfert du réseau électrique domestique, support des CPL.

Mühl, Gero. "Large-Scale Content-Based Publish-Subscribe Systems". Phd thesis, 2002. http://tuprints.ulb.tu-darmstadt.de/274/1/dissFinal.pdf.
Testo completoAbstract (sommario):
Today, the architecture of distributed computer systems is dominated by client/server platforms relying on synchronous request/reply. This architecture is not well suited to implement information-driven applications like news delivery, stock quoting, air traffic control, and dissemination of auction bids due to the inherent mismatch between the demands of these applications and the characteristics of those platforms. In contrast to that, publish/subscribe directly reflects the intrinsic behavior of information-driven applications because communication here is indirect and initiated by producers of information: Producers publish notifications and these are delivered to subscribed consumers by the help of a notification service that decouples the producers and the consumers. Therefore, publish/subscribe should be the first choice for implementing such applications. The expressiveness of the notification selection mechanism used by the consumers to describe the notifications they are interested in is crucial for the flexibility of a notification service. Content-based notification selection is most expressive because it allows to evaluate filter predicates over the whole content of a notification. The advantage in expressiveness compared to channel- or subject-based selection results in increased flexibility facilitating extensibility and change. On the other hand, scalable implementations of content-based notification services are difficult to realize. Indeed, the expressiveness of notification selection must be carefully chosen in large-scale systems, because expressiveness and scalability are interdependent. Hence, the most fundamental problem in the area of content-based publish/subscribe systems is probably the scalable routing of notifications from their producers to their respective consumers. Unfortunately, existing content-based notification services are not mature enough to be used in large-scale, widely-distributed environments. Most existing notification services are either centralized, use flooding, or use simple routing algorithms that assume that each event broker has global knowledge about all active subscriptions. All these approaches exhibit severe scalability problems in large-scale systems. In contrast to that, this thesis concentrates on mechanisms to improve the scalability of content-based routing algorithms and presents more advanced routing algorithms that do not rely on global knowledge. The algorithms presented here exploit similarities between subscriptions by using identity- and covering-tests, and by merging filters. While identity-based routing is a simplified version of covering-based routing, merging-based routing is more advanced because it exploits the concept of filter merging. Furthermore, the idea of imperfect routing algorithms is introduced. The thesis consists of a theoretical and a practical part. The theoretical part presents a formal specification of publish/subscribe systems, a routing framework and a set of routing algorithms, and discusses how the routing optimizations can be broken down to the actual data/filter model. The practical part presents the implementation of the Rebeca notification service which supports advertisements and all the routing algorithms mentioned above. A detailed practical evaluation of the implemented algorithms based upon the prototype is also presented.

Frey, Davide. "Publish Subscribe on Large-Scale Dynamic Topologies: Routing and Overlay Management". Phd thesis, 2006. http://tel.archives-ouvertes.fr/tel-00739652.
Testo completoAbstract (sommario):
Content-based publish-subscribe is emerging as a communication paradigm able to meet the demands of highly dynamic distributed applications, such as those made popular by mobile computing and peer-to-peer networks. Nevertheless, the available systems implementing this communication model are still unable to cope efficiently with dynamic changes to the topology of their distributed dispatching infrastructure. This hampers their applicability in the aforementioned scenarios. This thesis addresses this problem and presents a complete approach to the reconfiguration of content-based publish-subscribe systems. In Part I, it proposes a layered architecture for reconfigurable publish-subscribe middleware consisting of an overlay, a routing, and an event-recovery layer. This architecture allows the same routing components to operate in different types of dynamic network environments, by exploiting different underlying overlays. Part II addresses the routing layer with new protocols to manage the recon- figuration of the routing information enabling the correct delivery of events to subscribers. When the overlay changes as a result of nodes joining or leaving the network or as a result of mobility, this information is updated so that routing can adapt to the new environment. Our protocols manage to achieve this with as little overhead as possible. Part III addresses the overlay layer and proposes two novel approaches for building and maintaining a connected topology in highly dynamic network sce- narios. The protocols we present achieve this goal, while managing node degree and keeping reconfigurations localized when possible. These properties allow our overlay managers to be applied not only in the context of publish-subscribe mid- dleware but also as enabling technologies for other communication paradigms like application-level multicast. Finally, the thesis integrates the overlay and routing layers into a single frame- work and evaluates their combined performance both in wired and in wireless scenarios. Results show that the optimizations provided by our routing reconfig- uration protocols allow the middleware to achieve very good performance in such networks. Moreover, they highlight that our overlay layer is able to optimize this performance even further, significantly reducing the network traffic generated by the routing layer. The protocols presented in this thesis are implemented in the REDS middle- ware framework developed at Politecnico di Milano. Their use enables REDS to operate efficiently in dynamic network scenarios ranging from large-scale peer-to- peer to mobile ad hoc networks.

This chapter turns to the world of social media and how it shapes Christian identities in Kenya, including Juliani's. It explores how even urban churches are tapping into such media to engage youth on matters of faith and lived sociocultural issues. Many Kenyan youth get access to the internet and such social-media platforms as Twitter and Facebook through their cell phones. Some service providers, such as Safaricom (the largest cell-phone company in Kenya), offer Facebook as part of their already installed applications for subscribers. Through mobile phone-based access to these kinds of platforms, Kenyan youth are able to virtually enter the wider world beyond their immediate environs, see life or constructions of it in other locations, imagine how it relates or contrasts or both with their own lives, and engage with it either by making meaning of their own lives or constructing it as they choose.

Testo completoAbstract (sommario):
Chapter 5 follows the investment chain from the ‘buy side’ of investment management into the ‘sell side’ of brokers and traders. It discusses the development of ‘dark pools’—private share-trading venues in which subscribers can bid to buy shares or offer to sell them without those bids or offers being visible to the market at large. Originally, access to dark pools was restricted to investment management firms, and the pools were intended to permit those firms to buy or sell large blocks of shares among themselves at low cost and without the ‘market impact’ of trading in the public markets. The history of dark pools, however, shows how hard it has been to cling to that vision in the face of investment chain entanglements. The entanglement on which the chapter focuses most relates to the ways of payments (colloquially known in the US as ‘soft dollars’) for sell-side research.

Testo completoAbstract (sommario):
This chapter examines the processes whereby shipping law may converge internationally in the absence of state intervention. It outlines a theory explaining such convergence through the operation of network effects. The theory is based on the argument that because legal standards are instruments that facilitate interaction with a larger group, the inherent value of a legal standard as a means to that end increases with the number of other people who also subscribe to and employ the same legal standard. Therefore, a particular standard emerges as the dominant standard as it becomes more widely used for such interactions, and the number of people adopting it in turn also increases. The chapter argues that shipping law is especially susceptible to network effects because it exhibits particularly high levels of interaction across the globe. These effects therefore form a good explanation for standardization of shipping norms.

The extractive industries have invariably occupied a somewhat uncomfortable position in development debate and practice. The very word ‘extraction’ conjures up images of forceful (and painful) removal. The media image is frequently one of despoiling nature, sometimes abusing and destroying the environment, including the resources (water, forests, soils etc.) essential to human life. Nor does mining infrastructure offer the same attractive photo opportunities for local politicians or for visiting ministers from aid-donor countries. In some cases there can be an imbalance of power between large extractives companies and host governments, and corruption and non-transparency are still to be found. This chapter lays out the framework of a book which certainly does not seek to present a rose-tinted view of the development benefits of extractives. Nor does it subscribe to the most negative manifestations of the resource curse thesis.

Between the late 1940s and the early 1970s, the word “automation” in the United States stood for a revolutionary development, although few could agree as to precisely what it described. Rather than a specific technology, however, this book shows that “automation” was a discourse defining work as mere biological survival that saw the end of human labor as the inevitable result of technological progress. In premising liberation on the end of work, subscribers to the automation discourse made political freedom contingent not on the distribution of power but on escape from the limits of the human body. Ironically, much of what was called “automation” in the postwar period did not actually abolish human labor. Abandoning the workplace as a site of political contest, unions largely failed to resist managers who sped up workers, broke unions, and sent jobs where non-unionized labor could be had more cheaply—all of which managers, lawmakers, and even union officials called progress. This book considers how different constituencies deployed the automation discourse to advance a politics that sought the abolition of work. Although existing scholarship concerning “automation” presumes that the word describes a clear-cut technology or industrial process, this book returns the concept to its ideological roots in the postwar United States. What most called “automation” often created more human labor or intensified labor already present.

This book identifies the core motivations of Donald Trump’s strongest supporters. Previous research suggests that Trump’s followers are authoritarians or even fascists—individuals who are comfortable only when a powerful person is controlling their lives and providing direction and certainty in the process. This book advances and empirically supports the thesis that what Trump’s base craves is not authority but rather a specific form of security. The disposition of Trump’s strongest supporters leads them to strive for security in the face of threats from members of out-groups, and they define out-groups broadly to include welfare cheats, unpatriotic athletes, norm violators, non-English speakers, people who subscribe to a non-majority religion, people not of the majority racial group, people who do not follow prevalent national customs, and certainly people from other countries. Fervent Trump supporters’ primary purpose in life is to protect themselves, their families, and their larger cultural group from these outsider threats. A similar motivation is present in subpopulations around the world as can be seen in the Brexit vote in the United Kingdom as well as the success of nativist candidates around the globe. By detailing these desires, this book makes it possible to understand a political movement that many people find baffling and frustrating, which in turn could make it easier for Trump’s base and those who stridently oppose Trump to communicate with each other.

With 225 million subscribers, India has the world’s third largest mobile subscriber base in the world. The Indian mobile industry is also one of the most competitive in the world with 4-7 operators in each service area. A large number of operators bring competition and its associated benefits such as decrease in price and hence corresponding growth of the market. On the other hand in the presence of economies of scale, too many operators may result in inefficient scales and high unit costs. This article analyses the trade-off between competition and economies of scale by estimating the production function for mobile subscribers and traffic carried. Analysis of panel data reveals the existence of economies of scale in the Indian mobile sector. We then derive an upper bound on the optimal number of operators in each license area and discuss policy implications.

This chapter on the consumption of mobile news in developing country draws on the limited but growing scholarship on journalism and mobile media. India, becomes an emblematic instance, as India's mobile phone subscriber base peaked to more than 1 billion users in late 2015, making India the second largest mobile phone user base. In recent years, mobile media in India have also penetrated individuals' news consumption and sharing behaviors. These emerging practices can be posited in relation to the ubiquitous presence of mobile devices and a steadily expanding digital ecosystem. Utilizing both quantitative and qualitative methods, this chapter seeks to explore how mobile apps position themselves into wider news media assemblages in a developing country like India and what are the factors that influence mobile apps usage for news consumption in India? Hence, broadly, the article aims to explore, how these emerging practices are transforming not only the dominant ways of distributing the news but also the very nature of the relationship between news media and its audience.

Content-based publish/subscribe systems offer an interaction scheme that is appropriate for a variety of large-scale dynamic applications. However, widespread use of these systems is hindered by a lack of suitable security services. In this paper, we present scalable solutions for confidentiality, integrity, and authentication for these systems. We also provide verifiable usage-based accounting services, which are required for e-commerce and e-business applications that use publish/subscribe systems. Our solutions are applicable in a setting where publishers and subscribers may not trust the publish/subscribe infrastructure.

This chapter explores a group of large city views, also known as long views, sponsored by local subscribers in Boston, New York, Philadelphia, and Charleston, and engraved in London. These prints perfected urban environments by eliminating spaces of unruly commerce and crime and celebrating residents’ architectural accomplishments. They contributed to colonists’ efforts to reduce the wilderness by adapting the prospect view and drawing upon the science of surveying. The views allowed subscribers to articulate their common goals for urban planning and hope for their cities’ growth. Intended for a British imperial audience, the prints also asserted colonial Americans’ civic growth and reminded British viewers of North America’s large size. Whereas English thinkers belittled America’s fauna and her land, colonial city views proclaimed North America’s magnitude.

Chapter 9 explores the results of the First External Loan. It provides a nationwide overview of the amounts raised by US state. It also notes the hostile response from the leadership of the ‘Friends of Irish Freedom’ organization. Then, combining a previously unknown register containing the names and addresses of 3,067 subscribers in Manhattan, New York, with the US Federal Census of 1920 and qualitative material from around the country, it provides the first large demographic analysis of supporters of Irish independence in America. It reveals characteristics such as the subscribers’ age, sex, literacy, birthplace, parents’ birthplace, native language, immigration date, marital status, home ownership status, occupation, and employment status. It then explores popular responses from the bond drive’s detractors. In particular, the characterization of subscribers as gullible female domestic servants is interrogated, tracing the trope back to nineteenth-century Irish-American fundraising. The prevalence of non-Irish supporters of the bond drive is also investigated, including Jewish-Americans, African-Americans, Chinese-Americans, and Americans born elsewhere in Europe.

There is increasing interest in utilizing optical code-division multiple-access (CDMA) schemes in fiber-optic local area networks because of its wide bandwidth, high information security, and the capability for multiple access. Both synchronous and asynchronous optical CDMA system have been actively studied. In general, the numbers of subscribers and the simultaneous users are larger in the synchronous CDMA although the system is more complex. However, a femtosecond CDMA scheme based on spectral encoding and decoding, which is categorized as an asynchronous scheme [1], can allow a large number of simultaneous users. [2] In this paper, we demonstrate the femtosecond code-division multiple-access based on spectral encoding of 1.3 μm Cr:forsterite laser.

Testo completoAbstract (sommario):
Recently, requirements have been increasing for large throughput networks for use in asynchronous transfer mode (ATM) cell transfer, for example, subscriber transfer network. In order to meet the requirements, optical networks adopting wavelength-division multiplexing (WDM) technologies, have been studied. The authors have recently proposed a WDM ring optical fiber network. In this paper, a novel control scheme for fast laser diode (LD) wavelength switching with rapid stabilizing is proposed, which is the key technology for the proposed network. Obtained characteristics are suited for 600Mb/s cell speed WDM ring network. The proposed control scheme can be applied to over 10Gb/s cell speed networks.

Testo completoAbstract (sommario):
The Covid-19 crisis has forced most governments around the world to close educational institutions in an attempt to contain the spread of the pandemic, impacting over 91% of the world’s student population according to UNESCO. Uganda is among the countries where schools have been closed for at least 2 years. Uganda subscribes to the UN’s 2030 sustainable development goal (SDG) 4 which is grounded on notions of equity and fairness. The SDG 4 agenda: ‘Ensures inclusive and equitable quality education and promotes lifelong learning opportunities for all’. Similarly, Uganda’s Education Sector Strategic Plan 2018-2020 stipulates delivery of equitable, relevant and quality education for all. Notably in Uganda, with 42 million people (UBOS 2020) in lock down and mostly confined in their homes, digital technologies are becoming a necessity, as they become one of the main ways to access education, but also one remaining vectors for social interactions to take place. For instance, the 2019 communication sector report by the Uganda Communications Commission shows that the country’s internet penetration stands at 37.9% with over 23 million internet users, who mostly use mobile phones. According to the same report, mobile internet subscription stood at between 14.3 to 15.2 million persons out of the 42 million Ugandans. Meanwhile about 1.1 million to 1.4 million Ugandans have actively subscribed to pay-tv services. This clearly shows the digital gap as of 2020, given that a large proportion of the population (estimated at 62-96%) does not have access to the internet or pay-tv. The present article aims to demonstrate that in the current Covid-19 crisis, much as digital technologies are helping to reach wider audiences globally, Uganda, like other Sub-Saharan African countries, still faces several challenges which directly or indirectly affect lifelong learning. Our hypothesis is that some of the most vulnerable students from Universities living in rural communities, people living with disability are the most difficult to reach if ICTS serve as the main instrument for promoting lifelong learning. A survey of a convenient sample of 350 Ugandan students from various socioeconomic backgrounds was conducted. Preliminary results show that despite the fact that digital technologies have enabled the closing of the gap of continued access to lifelong learning during the Covid-19 pandemic in Uganda, there are still existing challenges in implementing Inclusive lifelong learning such as mobile phones, unstable electricity, poor infrastructure and accessing the lowest technology in order to close the educational gap.

Testo completoAbstract (sommario):
B-ISDN requires a throughput in excess of 50 Gbit/s, even in a subscriber loop for full-motion video transmission. To provide the network capacity and to provide flexibility, optical signal processing technology is used, especially that of optical wavelength-division multiplexing. We have already proposed such configuration of photonic cross-connect nodes that perform nonblocking cross-connection with two stages by utilizing multi wavelength selective filters(MWSFs)[1]. In our proposed configuration, a large capacity can be provided with multistage connection, and signal wavelength conversion will be essential at the connecting stage between two groups of the basic switches when connected by multiple stages. In the connecting stage, use of wavelength conversion devices (WCDs) such as wavelength conversion lasers(WCLDs) has the advantage of hardware scale reduction in large-scale connecting systems, thus eliminating electronic circuits such as O/E or E/O converters.
