Every minute a woman dies due to pregnancy related complications globally, and half of these deaths occur in the developing countries. Despite knowing the main causes of these deaths, maternal mortality has remained high especially in Sub-Saharan Africa with 536,000 deaths annually. One of the main challenges is access to maternal health services. This study aims at assessing whether mobile tel...

This paper analyzes price elasticities in the Austrian market for mobile telecommunications services using data on firm specific tariffs. Both static and a dynamic panel data approaches lead to consistent results which provide evidence for a relatively elastic demand. Furthermore, some basic facts on the Austrian mobile telephone sector are presented. JEL-Classification: C23, L13, L96.

In this paper, we study the fundamental problem of gossip in the mobile telephone model: a recently introduced variation of the classical telephone model modified to better describe the local peer-to-peer communication services implemented in many popular smartphone operating systems. In more detail, the mobile telephone model differs from the classical telephone model in three ways: (1) each d...

In this paper, we study PUSH-PULL style rumor spreading algorithms in the mobile telephone model, a variant of the classical telephone model in which each node can participate in at most one connection per round; i.e., you can no longer have multiple nodes pull information from the same source in a single round. Our model also includes two new parameterized generalizations: (1) the network topo...

Studies on gender and telephony tend to be quantitative and depict the purposes for which women and men use mobile telephones and landlines. Qualitative studies on the topic predominantly rely on face-to-face interviews to examine how telephone use genders space. We suggest these traditional methods of data collection leave unexamined the emotional and social relationships that emerge and are e...

In this paper, we discuss security issues associated with mobile telephone networks and focus on the unique issues that appear due to the mobility of the user. We provide an overview of how some of these issues are addressed in the second-generation mobile network GSM and consider some of the possible shortcomings of that network. We then compare security features in GSM with those implemented ...

OBJECTIVES This study sought to determine, in vivo, whether electromagnetic interference (EMI), generated by North American Digital Communications (NADC)/Time Division Multiple Access-50-Hz (TDMA-50) mobile cellular digital telephone model AT&T 6650, disturbs normal implantable cardioverter-defibrillator (ICD) operation and to verify these observations in vitro by testing a selection of telepho...

Current cellular telephone system is vulnerable to various attacks. With more complicated equipments, it is possible to receive the ESN and PIN of legal user and use them to commit cellular telephone frauds. Generally, the frauds can be classified into three: subscription fraud, technical fraud, and internal fraud. This paper analyses the frauds in cellular mobile communication and provides an ...

The present study aims to investigate the relative effectiveness of different types of pragmatic instruction including two collaborative translation tasks and two structured input tasks with and without explicit pragmatic instruction on the production of apologetic utterances by low-intermediate EFL learners. One hundred and fifty university students in four experimental groups and one control ...

Wireless technologies, under the ‘‘Anywhere, Anytime’’ paradigm, offer users the promise of being always attached to the network. Mobile devices enabled with multiple wireless technologies make possible to maintain seamless connectivity in highly dynamic scenarios such as vehicular networks (VNs), switching from one wireless network to another by using vertical handover techniques (VHO). In thi...
