Nowadays, there is a wide range of commercial LBMS (Location-Based Mobile Services) available in the market, mainly in the form of GPS-based navigation solutions, and a trend towards the display of 3D maps can be clearly observed. Given the complete disparity of ideas and a visible commercial orientation in the industry, the study of the visualisation aspects that influence user performance and experience in the exploration of urban environments using 3D maps becomes an important issue. In this work, a generic conceptual framework is proposed whose main purpose is to objectively evaluate the impact and contribution of the major visualisation elements involved (henceforth mentioned as feature vectors). With this framework in mind, an online questionnaire was developed and administered to 149 test subjects in order to measure the real impact of feature vectors. The results clearly demonstrated that certain features have clear impact on user performance, and should be taken in account in LBMS development. As an example, just by displaying buildings with a 3D appearance, subjects were able to match more accurately the real environment with the one presented on a mobile device. In general, users were able to perform the tasks entrusted to them faster...

In response to a growing interest in networked communications at sea as well as the needs of our vital commercial fishing industry, the Northeast Consortium funded a novel research initiative to establish wireless acoustic and radio communications at sea. The platform used for this type of telemetry instrumentation was to be a buoy which could not only withstand the often harsh conditions off the northeastern coast of America (specifically, Cape Ann), but do so while exhibiting an exceptionally small response in heave and roll. A spar type buoy was designed and built at the MIT Sea Grant facility. Spars are a special type of buoy shape whose hydrostatic and hydrodynamic interactions with the sea are decoupled enough so that extreme sea conditions do not induce extreme buoy motions. Most oceanographic buoys are of the discus type, and move as the surface of the ocean does. This type of wave-following buoy would not sufficiently facilitate the requirements of the high-bandwidth wireless networking hardware, and therefore would not serve the current purpose.; (cont.) The NEC buoy displaces approximately 140 kg of sea water and is roughly 11 feet long when fully assembled, not including its 5 foot antenna mast. The buoy employs a PC104 stack to control an 802.1 lb wireless card and antenna...

This book presents a new paradigm for introducing technology in the microfinance industry of Bangladesh that could help ameliorate current constraints. Under the new paradigm, a centralized Information and communication technology (ICT) platform will be established to serve the microfinance industry of Bangladesh and technology will be deployed more rapidly to Microfinance Institutions (MFIs) in all parts of the microfinance value chain, from the head office to branch offices, loan officers, and clients. Unlike in the traditional paradigm, the technology needs of all MFIs will be pooled together in one central office. The central office will offer technology tools, services, and know-how to MFIs throughout the country. Several benefits will be achieved under this new paradigm: i) because all technology needs will be pooled in one place, the central office will be able to exploit economies of scale and offer technology services to MFIs at a lower cost; and ii) because their technology needs will be outsourced...

The transport sector is especially vulnerable to HIV/AIDS. Transport workers including long distance truck drivers, seafarers, airline crews and infrastructure construction workers spend long periods of time away from home, often endure harsh working conditions, and may engage in unsafe behavior that can lead to infection. Their mobility makes it difficult to access health information and treatment, or to maintain drug regimen. Transport hubs and construction sites are often considered hot spots due to the influx and interaction that take place among the mobile workers. Furthermore, the sector works as a vector for HIV spread as the opening of new roads connects low and high prevalence areas. The World Bank transport group has been proactively mainstreaming HIV response by assisting client governments to design and implement sector-level interventions. Programs are most developed in the highest prevalence areas, initially in Sub-Sahara Africa and now also in Asia. Support to the sector includes organizing training events to increase staff awareness and knowledge...

This study intends to increase understanding of how different types of mobile money services have developed in different environments. For this purpose, two countries were selected, the Republic of Korea and Uganda. From these study cases, some conclusions emerge. The development of mobile banking services can appear at different stages of financial sector development, but it requires a vibrant and competitive telecommunications sector. The regulatory environment does not need to be very sophisticated for the mobile industry to emerge. However, some elements appear to be important. The legal framework should allow (or at least not explicitly forbid) nonbank financial institutions to issue money and use banking agents or correspondents. To ensure wider use of the service by the population, it is important to educate the population on the benefits of mobile money services.

Although a number of m-money businesses have emerged around the world, few have reached significant scale. Overall, m-money uptake is limited when contrasted with its apparent promise of reaching the unbanked and underserved, servicing existing banking clients, and being a means for realizing a cashless society. This study examines the following in more detail: existing major money flows and the critical mass of low-value, high-volume payment transactions and whether m-money can be used for them (i.e., potential demand); regulatory environment and major obstacles for m-money uptake; business models of partnering institutions; payment behavior of users and nonusers (banked and unbanked), in particular where they receive funds and how they use money, including alternative means; and existing and potential agents networks, their requirements to run m-money as a viable business, and their training needs. This report provides detailed information on Thailand regarding five main topics, business models, money flows and demand...

This study presents the vision and implementation recommendations for the electronic identity based service delivery framework (EISDF) in Vietnam. It also delineates the roles to be played by the diverse stakeholders (private, public, development community, etc.) in the field. The study recommends various relevant and innovative electronic identity (eID) services that can be implemented to transform and enhance the accountability and efficiency of service delivery across sectors. These recommendations are based on the stocktaking of international experiences and identified possibilities based on the country assessment. Special emphasis is placed on eID systems that operate on mobile phones, and on those that have the potential of being scaled up by both the public and private sectors in Vietnam. The eID systems can help reduce identity fraud and enable individuals to avail of services more securely in a variety of contexts as in mobile banking and mobile applications for health care.

Wireless communications technologies play an essential role to support the Public Protection and Disaster Relief (PPDR) operational needs. The current Private/Professional Mobile Radio (PMR) technologies used for PPDR communications offer a rich set of voice-centric services but have very limited data transmission capabilities, which are unable to handle the increasing PPDR community demand for a wider range of data-centric services. Though some efforts have been devoted to upgrade PMR technologies with better data transfer capabilities, the progression towards an enhanced mobile broadband PMR standardized solution still lags behind the achievements made in the commercial wireless industry, which recently culminated in Long-Term Evolution (LTE) technology. Because of this contrasting progress, the adoption of commercial mainstream LTE technology to satisfy the PPDR community’s data communication needs is gaining momentum and offers significant opportunities to create and exploit the synergies between the commercial and PPDR domains, which have remained almost entirely separate to date. In this context, this paper first discusses the suitability of LTE and related technologies for mobile broadband PPDR service provisioning. Next, it presents the argument that the most plausible future scenarios to deliver the increasingly data-intensive applications demanded by the PPDR agencies are expected to rely on the use of both dedicated and commercial LTE-based mobile networks. From this basis...

Wireless networks increasingly utilize diverse spectral bands, which exhibit vast differences in transmission range, bandwidth and available airtime. While tremendous efforts have been devoted to enable efficient mobile access of single-band networks and increase their throughput, e.g., via network coding, such single-band solutions are unfortunately oblivious to the diversity and abundance of the available spectral bands. In this thesis, I present and evaluate novel schemes for mobile access and for throughput increase using network coding, schemes that are designed for diverse-band wireless networks, i.e., networks operating in multiple diverse bands. Specifically, I introduce the first scheme designed for mobile clients to evaluate and select both APs and spectral bands in diverse-band networks. The fundamental problem is that the potentially vast number of spectrum and AP options may render scanning prohibitive. Thus, my key technique is for clients to infer the critical metrics of channel quality and available airtime for their current location and bands using limited measurements collected in other bands and at other locations. I evaluate my scheme via experiments and emulations, which are enabled by a four-band testbed that I deploy. A key finding is that under a diverse set of operating conditions...

MBA Professional Report; The Defense (DoD) lags behind commercial entities in terms of adopting mobile computing technologies. Commercial smartphones offer scalable solutions to meet requirements ranging from business functions to tactical operations; however, these solutions require considerations beyond those applicable to the commercial sector. This research identifies whether potential solutions may contribute to three objectives: 1) reduce the DoD's currently high device and service costs; 2) increase the DoD's smartphone functionality; 3) maintain or increase the level of security functionality available in commercial devices for DoD. A strategic analysis of the commercial mobile communications industry highlights the business drivers and motivations of industry participants. This information is used to identify the DoD's strategic options, which, in turn, serve as the basis of business cases for adopting future smartphone capabilities. Business case analyses compare proposed cost models with the cost models for current smartphone implementations. Results indicate growing strategic opportunities for the DoD to acquire more economical commercial handsets and more flexible network services. The business cases may potentially save billions of dollars over seven years-i.e....

Understanding mobile phone users' behaviour and sentiment is essential for the commercial success of mobile content and information services. This paper aims to enhance this understanding through analysing data gathered from a consumer survey. We report on a broad survey of over 6000 Australian mobile phone users, covering respondents' behaviour and preferences on a range of variables relevant to the consumption of mobile content and information services. Findings from this research inform application developers, content aggregators, content owners, mobile telecommunication companies, handset manufacturers, analysts and other industry partners and may also help to establish guidelines for telecommunication carriers and government policy makers.; Kieran O'Doherty, Sally Rao Hill, Marisa Maio Mackay and Jason McPherson

In South Australia, overabundant kangaroo populations are managed through commercial harvest. Kangaroo harvest rates over the past decade have averaged only 40% of the harvest quota despite strong demand for the product. With kangaroo populations increasing, the problem of low kangaroo harvest rate in South Australia requires research attention. Previous research regarding kangaroo harvest has focused on questions of biology and ecology and little attention has been directed towards advancing understanding of the human dimensions of kangaroo management. This research sought to fill this gap in knowledge. Qualitative research methods were most appropriate due to the focus on social and institutional dimensions of kangaroo management. Data were collected during interviews with people involved in commercial kangaroo harvest: landholders, harvesters and meat processors. The main topics covered were regnlations and policy, economic issues, the rights and interests of various industry stakeholders and South Australian harvest rates. The views of Aboriginal people were also sought including the significance of kangaroos to Aboriginal people, access to kangaroos for subsistence harvest, kangaroo management and the kangaroo industry. The main findings of this research are presented as a series of peer-reviewed articles: • Article I introduces the research topic and presents preliminary findings of this study. • Article 2 establishes that an increase in South Australia's low harvest rate is needed if kangaroo harvest is to make greater contributions to regional communities...

The Bangladesh financial system, particularly banking and microfinance, has grown and developed since 2003 against the backdrop of 6 percent average Gross Domestic Product (GDP) growth. Banks' total assets and private credit ratios to GDP have each increased by about one-third since the 2003 Financial Sector Assessment Program (FSAP). Bank deposits, as a percentage of GDP, are comparable to other South Asian countries. Private domestic banks now hold a majority of bank assets; the shares of state-owned commercial banks (SCBs) and specialized banks (SBs) have declined correspondingly. Bank branches, access to banking, and microfinance services have expanded substantially. Nonbanking financial institutions have also grown but remain small; banks s till account for over 90 percent of financial institutions' assets. Equity market listings and capitalization have grown substantially; market capitalization was equivalent to about 14 percent of GDP in December 2008. A government bond market is developing. Further sound financial development in the various parts of the financial sector...

Although Kenya's financial system is by far the largest and most developed in East Africa and its stability has improved significantly over the past years, many challenges remain. This paper assesses the stability, efficiency, and outreach of Kenya's banking system, using aggregate, bank-level, and survey data. Banks' asset quality and liquidity positions have improved, making the system more resistant to shocks, and interest rate spreads have declined, in part due to reduction in the overhead costs of foreign banks. Outreach remains limited, but has improved in recent years, driven by mobile payments services in the domestic remittance market. Fostering a level regulatory playing field for all deposit-taking institutions is a key remaining challenge. Specifically, an effective but not overly burdensome framework for regulation and supervision of microfinance institutions and cooperatives is a priority. Maintaining an openness to new, and non-bank, providers of financial services, which has enabled the success of mobile payments...

Banking the Poor presents new data collected from two sources: central banks, and leading commercial banks in each surveyed country. It explores associations between countries' banking policies and practices, and their levels of financial access measured in terms of the numbers of bank accounts per thousand adults. It builds on the previous work of measuring financial access through information obtained from regulators, banks, and household surveys. It explores associations between countries' banking policies and practices, and their levels of financial access, measured in terms of the numbers of bank accounts per thousand adults. The extent to which people are banked depends primarily on how wealthy they are. Even in the poorest countries, rich urban customers get access to good banking. Although there are a range of financial services used by the poorest, these are usually provided outside the formal banking system. Banks are used by those above this threshold, usually by salaried employees who have the steady income. Naturally banks are more likely to seek out users with a steady, predicatable income. Expanding credit for enterprises leads to the creation of a salaried class that wants to bank: this is the primary way to increase bank access. While bank clients make up the largest part of those using financial services in most countries...

Sri Lanka's population is still largely rural, nearly 85 percent lives outside of cities. There will probably be rural-to-urban migration in the future, which represents a potential opportunity to m-money providers. People working in cities often wish to repatriate their savings to their rural families conveniently and at a low cost. Income is fairly evenly spread across Sri Lanka s provinces, with the exception of the Western Province where Colombo, the largest city, is situated. Its GDP per capita places Sri Lanka near the average of comparable Southeast Asian countries. Malaysia is clearly an outlier with a considerably higher GDP per capita, but Sri Lanka s GDP is higher than that of the Philippines, where m-money has taken off dramatically. Poverty is less of a problem in Sri Lanka relative to countries like Bangladesh or Cambodia, where GDP per capita is much lower. The key point is that Sri Lanka is at a different stage in its economic development and is unlikely to have the same socioeconomic conditions that made m-money in Kenya accelerate so rapidly.

This report analyzes possibilities for increasing revenues for India Post through expanding channeling of financial services. The Indian postal network is among the largest networks in the world in terms of area covered and population served, and constitutes an important mechanism of achieving transportation and communication. Within India Post, the Post Office Savings Bank (POSB) is one of the oldest and largest financial institutions (with largest deposit base) in the country. The key objective of POSB is to provide people living in rural, semi-urban, remote and inaccessible areas of the country with an easy and reliable means of making investments, making remittances and operating savings accounts. It is of strategic importance for POSB to increase market-based revenues so as to gain better control of its market orientation and revenue structure. In addition, though POSB still retains competitive advantages over commercial banks, it will not be long before the competition replicates these advantages. Hence...

As Android smartphones gain popularity, industry and government will face increasing pressure to integrate them into their environments. The implementation of these devices on an enterprise can save on costs and add capabilities previously unavailable; however, the organizations that incorporate this technology must be prepared to mitigate the associated risks. These devices can contain vast amounts of personal and work-related data that can impact internal investigations, including (but not limited to) those of policy violations, intellectual property theft, misuse, embezzlement, sabotage, and espionage. Physical access has been the traditional method for retrieving data useful to these investigations from Android devices, with the exception of some limited collection abilities in commercial mobile device management systems and remote enterprise forensics tools. As part of this thesis, a prototype enterprise monitoring system for Android smartphones was developed to continuously collect many of the data sets of interest to incident responders, security auditors, proactive security monitors, and forensic investigators. Many of the data sets covered were not found in other available enterprise monitoring tools. The prototype system neither requires root access privileges nor exploiting weaknesses in the Android architecture for proper operation...
