Women, Empowerment, and Mobile Phones in the Developing World

2020

This chapter surveys and analyzes recent literature on mobile communication to examine its relationship to gender and development, more specifically how women in developing countries use and are impacted by mobile phones. Focusing on issues of power, agency, and social status, the chapter reviews how mobile telephony has been found to be implicated in patriarchal bargaining in different societies, how privacy and control are enabled through it, what benefits have been shown to accrue to women using mobile phones, and what barriers, limitations, and disadvantages of mobile use exist for women and why. The conclusion urges more gender-disaggregated analysis of mobile phone impact and use and …

The Developmental Contribution From Mobile Phones Across the Agricultural Value Chain in Rural Africa

2011

Published version of an article from the journal: The Electronic Journal of Information Systems in Developing Countries. Also available fro the publisher: http://www.ejisdc.org/Ojs2/index.php/ejisdc/article/viewFile/849/377 The most widespread information and communication technology (ICT) in developing countries today is the mobile phone. The majority of people in the least developed countries still live in rural areas and their livelihood depends on the primary industries. This study investigates the use of mobile phones among farmers in rural Tanzania in order to supply empirical data on the developmental role of this technology. The results show that the improved access to communication…

Sex, social reproduction, and mobile telephony as responses to precarity in urban Tanzania

2019

The gendered effects of neoliberal economic restructuring around the world are usually studied in their most dramatic forms: cross-border migration, exploitation, resistance, and violence. This chapter examines significant transformations arising from economic restructuring in the nexus between gender, labour, and urban space — transformations in which mobile technologies are deeply implicated. It explores how mobile phones are used by the poor for day-to-day survival in Tanzania’s largest city. The chapter shows how gendered economic bargains are negotiated at the very bottom of a survival economy located within the dynamics of a globalized economic system. An important characteristic of m…

More firms, more competition? The case of the fourth operator in France's mobile phone market

2010

Accepted, Forthcoming; International audience; To foster competition the French government authorized a fourth operator, ‘Free', to enter the country's mobile phone market at the end of 2009 alongside Orange, SFR and Bouygues Telecom (BT), who held respectively one-half, one-third and one-sixth of the market. By using a stylized model of France's phone market, we have examined what we call the regulator's nightmares and dreams. If Cournot competition is in place before Free's entry, minimizing the total profit fails to maximize the consumer surplus and the total surplus; the maximum most realistic price fall is 6.7% compared to three-way competition and could be 1.7% only; if Orange, SFR an…

Mobile telephony in emerging markets: The importance of dual-SIM phones

2020

Abstract A substantial share of customers in emerging markets use dual-SIM phones and subscribe to two mobile networks. A primary motive for so called multi-simming is to take advantage of cheap on-net services from both networks. In our modelling effort, we augment the seminal model of competing telephone networks á la Laffont, Rey and Tirole (1998b) by a segment of flexible price hunters that may choose to multi-sim. According to our findings, in equilibrium, the networks set a high off-net price in the linear tariffs to achieve segmentation. This induces the price hunters to multi-sim. We show that increased deployment of dual-SIM phones may induce a mixing equilibrium with high expected…

Les TIC en la formació universitària de mestres. El telèfon mòbil en Didàctica de l'Expressió Plàstica a la Facultat de Magisteri de la Universitat d…

2017

La present investigació pretén promoure l’ús de les TIC en l’àrea de Didàctica de l’Expressió Plàstica de la Facultat de Magisteri per contribuir a un coherent desenvolupament de l’Educació Artística amb la realitat social i cultural del segle XXI, des de la dimensió tecnològica. L’estudi respon a la necessitat d’analitzar de manera rigorosa, des de la Didàctica de les Arts Visuals, la percepció que de l’ús pedagògic de les tecnologies de la informació i la comunicació tenen determinats grups d’estudiants universitaris de Magisteri. En concret estudiarem i avaluarem la resposta que donen a l’ús educatiu del telèfon mòbil com a plataforma multimèdia en xarxa, en el tractament de continguts r…

Sistemas de respuesta inmediata en el aula: una experiencia de evaluación formativa en educación física.

2017

Resumen: La necesidad de mejorar los procesos de evaluación es una prioridad para el profesorado y las instituciones educativas. Pese a ello, implementar la evaluación formativa y democrática de calidad en disciplinas como educación física, resulta difícil por las barreras existentes: la ratio alumnado-profesorado por curso y por clase, el escaso tiempo de acción didáctica o por la dificultad de obtener información sobre los tres dominios de aprendizaje disciplinares psicomotor, cognitivo y socio-afectivo (Díaz, 2015; Krause, O'Neil, & Dauenhauer 2017). Las TIC, especialmente el Mobile learning, ofrecen un inédito escenario de posibilidades para mejorar la evaluación del alumnado, del profe…

2020

[EN] This work focuses on the visual narratives generated from images captured by art education students, as a result of projects developed in the Teaching classrooms during different academic years. In them intervenes, at first, the gaze of the students as visual producers through portable devices, mainly mobile phones, in educational environments between 2011 and 2017. The images were captured at different chronological moments and materialized on the university campuses of Ontinyent and Dels Tarongers, from the Faculty of Education. The work theoretically approximates the method of Research Based on the Arts. The images produced by the students are composed by the author and researcher t…

Reconsidering off-task: a comparative study of PDA-mediated activities in four classrooms

2010

Mobile technology is ubiquitous and diverse and permeates many aspects of daily life at home, during leisure activities, and in public spaces. The study presented here is of two sixth grade classes in Michigan, USA and two seventh grade classes in Norway. The students and the teachers in these four classrooms were equipped with mobile technologies (PDAs). We found that the students’ PDA-mediated actions in the classroom were not exclusively used for the tasks and activities set by the teacher, but that the students also used the PDAs on their own initiative – so-called ‘off-task’ activities. We analyze the findings by reconsidering off-task activities from a sociocultural perspective.

Fog Computing based traffic Safety for Connected Vulnerable Road Users

2019

Annually, millions of people die and many more sustain non-fatal injuries because of road traffic crashes. Despite multitude of countermeasures, the number of causalities and disabilities owing to traffic accidents are increasing each year causing grinding social, economic, and health problems. Due to their high volume and lack of protective-shells, more than half of road traffic deaths are imputed to vulnerable road users (VRUs): pedestrians, cyclists and motorcyclists. Mobile devices combined with fog computing can provide feasible solutions to protect VRUs by predicting collusions and warning users of an imminent traffic accident. Mobile devices’ ubiquity and high computational capabilit…
