This paper is an attempt at clarifying the essential contours of the phenomenon that grounds the developments in contemporary mobile communication: the mobile phone. In so doing our investigation intends to answer the question of what a mobile phone is as such. The paper presents a description of the mobile phone and its contextualisation within some of the works of Martin Heidegger (1889-1976), seeking to uncover the essential mode in which a mobile phone is what it is. Grounding our analysis on the ontology of Heidegger’s Being and Time (Heidegger 1962), we claim that the mobile phone will only show itself as what it is in its being in-the-world where mobile phones are what they are. This analysis is complemented by an exploration of the relevance of another of Heidegger’s notions, that of Ge-stell (Heidegger 1977) as the essence of modern technology, for the understanding of human involvement with mobile phones. Against this ontological background, our analysis points out being-with, bringing together and timing as the essential contours of the mobile phone, all of these suggesting the deeper notions of actual situation and of disembodiment.; Este paper investiga os contornos essenciais do fenómeno sobre o qual assentam os actuais desenvolvimentos na comunicação móvel: o telemóvel.

Our lives are increasingly performed within a mobile context. The current trend in Europe and the USA is a balance between men and women in mobile phone usage. Nevertheless usage parity does not mean usage equality. It is mostly ignored that women’s appropriation of the mobile phone is very distinct from men’s, similarly to what happens with other technological objects. Grounding the research in feminist media theory, this paper offers a view of the mobile phone as a technology of gender. I seek to show that the mobile phone contributes to gender construction and transformation. The paper begins with an analysis of the state of the art of feminist media studies. It follows by discussing the mobile phone as a media and its dichotomous position with regards to gender. The paper finalizes with a proposition of the mobile phone as a technology of gender, a place for gender transgression and possible transformation.; As nossas vidas são crescentemente vividas num contexto móvel. A tendência actual na Europa e nos EUA é a da paridade entre homens e mulheres no uso do telemóvel. No entanto paridade no uso não significa igualdade. Tal como acontece com outros artefactos tecnológicos, despreza-se muitas vezes o facto de as mulheres terem uma apropriação muito distinta do telemóvel. No âmbito dos estudos feministas dos media procurar-se-á perspectivar o telemóvel como uma «tecnologia de género» e demonstrar o seu contributo para a construção e transformação de género. O artigo começa por analisar o estado da arte dos estudos feministas dos media e prossegue com a discussão do telemóvel como um media e com o seu posicionamento dicotómico no que diz respeito ao género. O artigo termina com a proposta do telemóvel como uma «tecnologia de género»...

INTRODUCTION: With the tremendous increase in number of mobile phone users world wide, the possible risks of this technology have become a serious concern. OBJECTIVE: We tested the effects of mobile phone exposure on spatial memory performance. MATERIALS AND METHODS: Male Wistar rats (10-12 weeks old) were exposed to 50 missed calls/day for 4 weeks from a GSM (900/1800MHz) mobile phone in vibratory mode (no ring tone). After the experimental period, the animals were tested for spatial memory performance using the Morris water maze test. RESULTS: Both phone exposed and control animals showed a significant decrease in escape time with training. Phone exposed animals had significantly (~3 times) higher mean latency to reach the target quadrant and spent significantly (~2 times) less time in the target quadrant than age- and sex-matched controls. CONCLUSION: Mobile phone exposure affected the acquisition of learned responses in Wistar rats. This in turn points to the poor spatial navigation and the object place configurations of the phone-exposed animals.

peer-reviewed; This paper was obtained through PEER (Publishing and the Ecology of European Research) http://www.peerproject.eu; Power dissipation levels in mobile phones continue to increase due to gaming, higher power applications, and increased functionality associated with the internet. The current cooling methodologies of natural convection and radiation limit the power dissipation within a mobile phone to between 1-2 W depending on size. As power dissipation levels increase, products such as mobile phones will require active cooling to ensure that the devices operate within an acceptable temperature envelop from both user comfort and reliability perspectives. In this paper, we focus on the applied thermal engineering problem of an active cooling solution within a typical mobile phone architecture by implementing a custom centrifugal fan within the mobile phone. Its performance is compared in terms of flow rates and pressure drops, allowable phone heat dissipation and maximum phone surface temperature as this is the user constraint for a variety of simulated PCB architectures in the mobile phone. Perforated plates with varying porosity through different size orifices are used to simulate these architectures. The results show that the power level dissipated by a phone for a constant surface temperature may be increased by ~50 - 75% depending on pressure drop induced by the internal phone architecture. Hence for successful implementation and efficient utilization of active cooling will require chip layout to be considered at the design stage.

Tobacco use, which is rising quickly in developing countries, kills 5.4 million people a year worldwide. This paper explores the impacts of mobile phone ownership on tobacco consumption. Indeed, mobile phone ownership could affect tobacco consumption because individuals might pay for their communication with money they would have spent on tobacco. Using panel data from 2,100 households in 135 communities of the Philippines collected in 2003 and 2006, the analysis finds that mobile phone ownership leads to a 20 percent decline in monthly tobacco consumption. Among households in which at least one member smoked in 2003, purchasing a mobile phone leads to a 32.6 percent decrease in tobacco consumption per adult over the age of 15. This is equivalent to one less pack of 20 cigarettes per month per adult. The results are robust to various estimation strategies. Further, they suggest that this impact materializes through a budget shift from tobacco to communication.

As mobile phone ownership rates have risen in Africa, there is increased interest in using mobile telephony as a data collection platform. This paper draws on two pilot projects that use mobile phone interviews for data collection in Tanzania and South Sudan. The experience was largely a success. High frequency panel data have been collected on a wide range of topics in a manner that is cost effective, flexible (questions can be changed over time) and rapid. And once households respond to the mobile phone interviews, they tend not to drop out: even after 33 rounds of interviews in the Tanzania survey, respondent fatigue proved not to be an issue. Attrition and non-response have been an issue in the Tanzania survey, but in ways that are related to the way this survey was originally set up and that are fixable. Data and reports from the Tanzania survey are available online and can be downloaded from: www.listeningtodar.org.

The proliferation of mobile phones in developing countries has generated a wave of interest in collecting high-frequency socioeconomic surveys using this technology. This paper considers lessons from one such survey effort in a difficult environment -- the South Sudan Experimental Phone Survey, which gathered data on living conditions, access to services, and citizen attitudes via monthly interviews by phones provided to respondents. Non-response, particularly in later rounds of the survey, was a substantial problem, largely due to erratic functioning of the mobile network. However, selection due to non-response does not appear to have markedly affected survey results. Response rates were much higher for respondents who owned their own phones. Both compensation provided to respondents in the form of airtime and the type of phone (solar-charged or traditional) were varied experimentally. The type of phone was uncorrelated with response rates and, contrary to expectation, attrition was slightly higher for those receiving the higher level of compensation. The South Sudan Experimental Phone Survey experience suggests that mobile phones can be a viable means of data collection for some purposes...

Mainly three functions of the mobile phone are utilized in developing countries: (i) voice, (ii) SMS, and (iii) mobile application. Through combining these functions, mobile phones have been used to collect data, provide information and services, and act as an intermediary platform to solve issues in different sectors. In regards with an employment issue, due to a coordination and information failure between the demand and supply side of the labor market, even those who are qualified and received training and education have not been able to get a job. While the demand for employment exists both in the formal and informal sectors, access to this information is limited to those who have a strong social network and references or have access to a job portal on the Internet. As a potential solution for equalizing information asymmetry, the mobile phone can act as an intermediary to connect job providers with job seekers. This paper explores six business models (Pakistan Urban Link and Support (PULS), Konbit, Babajob, Assured Labor...

Objectives: The aim of this study was to quantify the level of handheld phone use when driving in South Australia. The study also sought to investigate any driver, site, and vehicle characteristics associated with handheld phone use to inform countermeasure development and publicity campaigns. Method: An on-road observational survey of handheld phone use was undertaken as part of a larger restraint use survey. The survey was conducted at 61 sites in metropolitan Adelaide and rural regions within South Australia on weekdays and a weekend in 2009. Results: A total of 64 (0.6%) of the 11,524 drivers observed during the survey were using handheld phones. Handheld phone usage rates ranged from 0.8 percent in metropolitan Adelaide to 0.3 percent in the rural region of The Riverland. Of all driver, site, and vehicle characteristics examined, the only statistically significant difference in handheld phone usage was for the number of vehicle occupants. The odds of a driver using a handheld phone while traveling alone was over 4 times higher than for a driver traveling with passengers. Conclusions: The level of handheld phone use among drivers in South Australia appears to be low relative to other jurisdictions. The level of enforcement activity and severity of penalties do not offer a clear explanation for the higher levels of compliance with phone laws. Given the rate of increase in phone technology...

Desarrollar una aplicación para dispositivos móviles no es una tarea sencilla, ya que precisamos no solo tener conocimientos de programación, sino que también tenemos que familiarizarnos muy bien con el entorno de desarrollo y el sistema operativo para el cual pretendemos crear la aplicación. Esto consiste en conocer en profundidad tanto las características técnicas de los dispositivos como las distintas APIs que tenemos a nuestra disposición. Hemos elegido Windows Phone 7.5 porque ha sido el último sistema operativo en llegar al mercado y ofrece interesantes novedades respecto a los otros dos grandes competidores, como son iOS, de Apple y Android, de Google. Por tanto, todavía es un gran desconocido y no existen muchos artículos que expliquen el desarrollo de aplicaciones. La explicación del desarrollo de la aplicación se centrará en el apartado lógico, ya que ésta es la gran cualidad de este sistema operativo. La de ofrecer un buen contenido antes que un buen diseño. Esto no quiere decir que dejemos de lado el diseño, sino que éste será sencillo. En este proyecto, se pretende explicar cómo desarrollar una aplicación móvil desde cero para el sistema operativo Windows Phone 7.5 y su posterior publicación en el Marketplace...

Mobile phone coverage has expanded considerably throughout the developing world, particularly within sub-Saharan Africa. Existing evidence suggests that increased access to information technology has improved agricultural market efficiency for consumer markets and certain commodities, but there is less evidence of its impact on producer markets. Building on the work of Aker (2010), this paper estimates the impact of mobile phone coverage on producer price dispersion for three commodities in Niger. The results suggest that mobile phone coverage reduces spatial producer price dispersion by 6 percent for cowpea, a semi-perishable commodity. These effects are strongest for remote markets and during certain periods of the year. The introduction of mobile phone coverage has no effect on producer price dispersion for millet and sorghum, two staple grains that are less perishable and are commonly stored by farmers. There are no impacts of mobile phone coverage on traders' gross margins or producer price levels...

A 2010 country governance and Anti-Corruption (CGAC) funded pilot in Guatemala employed entry-level mobile phones in conjunction with Episurveyor, a free, web-based software for data collection, to drastically reduce costs, facilitate accuracy and accelerate implementation of a nationally-representative beneficiary survey of Guatemala's conditional cash transfer program. As such it illustrates the potential of mobile phone-based data collection to strengthen program monitoring, evaluation and implementation, in particular in remote and marginalized areas highly populated by indigenous peoples.

Most discussions of the digital divide treat it as a "North-South" issue, but the conventional dichotomy doesn't apply to cell phones in Sub-Saharan Africa. Although almost all Sub-Saharan countries are poor by international standards, they exhibit great disparities in coverage by cell telephone systems. Buys, Dasgupta, Thomas and Wheeler investigate the determinants of these disparities with a spatially-disaggregated model that employs locational information for cell-phone towers across over 990,000 4.6-km grid squares in Sub-Saharan Africa. Using probit techniques, a probability model with adjustments for spatial autocorrelation has been estimated that relates the likelihood of cell-tower location within a grid square to potential market size (proximate population); installation and maintenance cost factors related to accessibility (elevation, slope, distance from a main road, distance from the nearest large city); and national competition policy. Probit estimates indicate strong, significant results for the supply-demand variables...

This paper focuses on the potentialities offered by mobile phone data to a reading of the site practices and rhythms of usage of the contemporary city by identifying the principal mobile practices of different urban populations. Beginning with the results of a research carried out in the Italian region of Lombardy, utilising mobile phone data provided by Telecom Italia, the paper will demonstrate how new maps, based on mobile phone data and better tailored to the dynamic processes taking place, can represent spatialized urban practices, provide new insights into the analysis of space-time patterns of mobility practices and be employed to recognise different "communities of practice". Mobile traffic data were treated as the effect of individual behaviours and habits that become aggregates, offering information about the features of usage of urban spaces that vary in time. The outcomes permit a visualisation of the spatial distribution of mobility flows, in addition to describing the experiential dimensions of commuting rhythms. It is possible to argue that commuting can be conceived as a mobile practice that exploits a rich variety of places of use in accordance with the temporal organisation of a day. The processing of mobile phone data...

Addiction to the Information and Communication Technologies (ICT) has become an important research topic. The aims of the present study were to determine the problematic uses of Internet and cell phones in Spanish teenagers and young students and analyze the predictive capacity of these problematic uses to explain scores on the CERI (Cuestionario de Experiencias Relacionadas con Internet) and CERM (Cuestionario de Experiencias Relacionadas con el Móvil). Three questionnaires were applied to 1,879 students: a general questionnaire for Internet and cell phone use, one scale for problematic use of Internet (CERI) and one for cell phone (CERM). Cluster analysis yielded a solution involving three groups for both CERI and for CERM: no problems, occasional problems and frequent problems. There were no differences between males and females in Internet but there were more females showing frequent problematic use of cell phone. A comparison with nine previous Spanish studies suggests that: a) the amount of time spent connected is not a good indicator of problems deriving from its use; b) the factor that could explain problematic use is altered identity communication (AIC), which occurs when users hide or alter their true identity; and c) population survey data alone do not allow to confirm the existence of a persistent addictive disorder related to ICT; Las adicciones a las Tecnologías de la Información y de la Comunicación han devenido una importante área de investigación. Los objetivos del estudio fueron caracterizar el posible uso problemático de Internet y móvil y analizar la capacidad predictiva de estos usos problemáticos para explicar las puntuaciones en el Cuestionario de Experiencias Relacionadas con Internet (CERI) y en el Cuestionario de Experiencias Relacionadas con el Móvil (CERM).

This paper analyzed the effects of electromagnetic (EM) radiation mobile phone on human head with different holding positions. The Em radiation is measured in terms of specific absorption rate (SAR). The human head exposed to global system for mobile communication (GSM) frequency bands. The radiation absorption analyzed through simulations by applying finite-difference time domain (FDTD) method using computer simulation technology (CST) microwave studio. The specific absorption rate (SAR) was measured for two common holding positions of mobile phone: Cheek and Tilt. In this tilt position, the mobile phone tilted for 15° and 30° from a person's head. SARs exhibited in much lower values as the mobile phone held in cheek position than that of tilt position. Helical antenna with substrate of Rogers RO3006 (loss free) found to be best tested substrate by resulted in lower SAR due to its lower conductivity properties than that of RO4003.

The goal of this study is to introduce the theoretical foundation of a new concept in medical technology that is centered on the cellular phone. The concept was conceived with the needs of medically underserved regions of Mexico in mind. The application introduced here deals with undetected intraperitoneal bleeding that is responsible for the death of one of four women who die at childbirths and that of 20% of accident trauma deaths; even brain trauma. The concept is made possible by the wide availability of cellular phone technology in Mexico, even in the poorest of regions, where other infrastructure is missing. The biophysical principles of the technology are based on the observation that electromagnetic properties of tissue change with disease and internal bleeding. We introduce a new paradigm of medical diagnostic in which inexpensive electromagnetic coils at the patient site are used to take bulk data from a magnetic field that is generated through the tissue or organ of interest. Instead of processing the data with a computer at the remote site the raw data is send via a cellular phone to a central facility that processes the raw data for the entire country or region. The diagnostic is returned in real time to the cellular phone at the patient site...

ABSTRACT In a competitive cell phone industry where consumers have a wide variety of cell phone brands to choose from, it is imperative for marketers to foster brand loyalty in order to establish enduring consumer-brand relationships. Nurturing brand romance has been suggested to marketers to cultivate emotional attachments between consumers and brands so as to increase brand loyalty. This study focussed on determining the extent to which the three underlying dimensions of brand romance, namely pleasure, arousal and dominance predict brand loyalty among cell phone users in the North West province. In total 371 respondents participated in the study. Results indicate that with respect to brand romance, respondents' current cell phone brands generate brand pleasure and brand arousal, but that these brands are not dominant in their minds. Although respondents participating in the study did not exhibit strong levels of brand loyalty towards their current cell phone brands, the three underlying dimensions of brand romance are statistically significant predictors of brand loyalty
