Long-distance transportation systems play an important role in economic growth. Yet, these systems are incurred with multifaceted delays and cost problems. The major incites affecting transportation systems are congestion, breakdowns, emergencies, and inclement weather. Scarcity of information about the environment also exacerbates travel problems. It is essential to employ monitoring and guidance that aid in making timely decisions through premediated information. This work aims to provide a flexible model for the long-distance transport system. The model is based on problems faced in long-distance transportation. Moreover, we examine the possible use of emerging Information and Communication Technologies (ICTs) for better transportation. The system dynamics study the problem at hand through cognitive agent-based modelling (ABM) concepts. The integrated model lays the rules to abate traffic delays. In this model, the distance travelled by vehicles is divided into sections using checkpoints. Every section is composed of different agents such as medical units, police stations, workshops, and petrol pumps. The vehicle shifts connection over the mobile ad hoc network (MANET) when enters or leaves a section. We used NetLogo for simulation of the model. A monitoring and guidance system is tested, and obtained results are analyzed by addressing problems causing delays. The guidance system helps vehicles to take optimal decisions for the time, congestion, and rests. The model can be used to improve decision-making for vehicles through premediated decisions. The proposed model can help to improve the efficiency of the transportation systems by reducing travel time.

Due to the increasingly widespread use of various information and communication technologies (ICT), individuals from different countries and cultures are able to learn and work collaboratively in virtual environments (Mowshowitz, 1997). Electronic communication tools, such as chat, e-mail, and the World Wide Web, now make it possible for students and employees to communicate and problem solve with colleagues irrespective of geographical location (Scott, 2000). One of the major downsides of this form of collaboration, though, is that members of a virtual team do not have the advantage of face-to-face interaction and communication. Instead they must rely solely upon an assortment of computer-supported cooperative-learning and class-work tools and strategies—some planned, some ad hoc—to coordinate resources (Bichelmeyer, Cagiltay, Evans, Paulus, & An, 2004). Unfortunately, little research has been conducted to systematically investigate the dialectic between culture and computermediated communication (CMC). There is currently an insufficient understanding of how individual learning and work, cultural features, and CMC mutually influence one another in a purposeful, virtual setting.

And Gender

Abstract In contemporary society, information and communication technologies (ICTs) are widely cherished for helping transnational households preserve a coherent sense of familyhood despite geographical separation. Despite ICTs having positive benefits for the maintenance of long-distance intimacies, digital asymmetries characterized by gaps in routines, emotional experiences, and outcomes of ICT use can also emerge between family members of different structural, social, and geographical conditions. Drawing on an innovative “content–context diary”-cum-participant observation, this article investigates the multi-dimensional digital asymmetries emerging from the transnational communication of Chinese “study mothers” in Singapore. Using the data visualization and analysis tool “ecomap,” the findings uncover that study mothers were largely beleaguered by expectation asymmetry and autonomy asymmetry, arising from different expectations to and control over daily transnational communication with their family members. The study mothers were disadvantaged by their relatively isolated life situations in the host society and accentuated gender hierarchies in the household.

This chapter examines the use of information and communication technologies (ICTs) by Mexican immigrant families living in the United States to care for their aged left-behind parents and grandparents suffering from poor health. It introduces the concepts of ‘rescue chain’ and ‘care talk’ to account for the interplay between ICTs and transnational families. Drawing on the stories of ten participants, the chapter considers how Mexican immigrants and their siblings, locally and abroad, form rescue chains to deliver care to ageing left-behind parents with health problems through ICTs. It shows that the rescue chain communication involves care talk that focused on protecting, providing, and proving that the care needs of the person in crisis were addressed. The chapter also reviews the literature on ageing and long-distance caring through ICTs, discusses theories on care and ageing, and explains the methodology and sources used in the study.

The Impact

The use of mobile devices in classrooms is becoming more and more common. The introduction of these resources to produce learning is part of the mobile learning methodology. Among the possibilities of these devices provide we can find, as an emerging technology, augmented reality, which combines elements of the real world with virtual images. The purpose of this paper is to know the impact of the augmented reality in the educational cooperatives of Andalusia. In this regard, educational cooperatives are centers characterized in their origin by promoting the development of methodologies based on Information and Communication Technologies (ICT). The data collection instrument used in this questionnaire is a quantitative methodology of a descriptive nature. The questionnaire was prepared ad hoc according to the existing literature and the answers coded on a Likert scale. The results show that only a minority of teachers implement the augmented reality in their classes. In addition, there are statistically significant differences in terms of professional experience, so that younger teachers tend to implement methodologies based on the use of emerging mobile technologies such as augmented reality. Finally, it is emphasized that despite the constant technological advance of mobile devices in society, their application in the classroom occurs slowly.

Abstract Advancements in information and communication technologies are encouraging researches in shared manufacturing systems, especially on current high-competitiveness and low-resources scenarios. This paper aims to compare productive resources sharing with traditional manufacturing systems by using a simulation-based optimization model. The model is based on the One Product Integrated Manufacturing paradigm in which the efficiency optimization is pursued by designing ad-hoc virtual factories allocating the best resources available on an existing network. The proposed simulation-based optimization model is capable of identifying the best production path and plan for different distances between network members. Along with a better overall efficiency, it is also possible to argue that dedicated virtual factories ease the identification of problems and allow for improvements without negatively affecting other resources.

Device-to-Device (D2D) is one of the emerging technologies expected to have significant contributions to the future of the Internet. The combination of personal mobile devices and D2D communications forms the Mobile Ad-hoc Network architecture, called MANETs. Nowadays, due to the flexibility and simplicity of establishing data transmission, MANETs are applied in various areas such as healthcare, intelligent transportation systems, tactical, smart retail, and smart agriculture. In practice, due to the mobility of network nodes, the network structure often changes, and the performance of MANETs is relatively low. Routing is one of the significant challenges of MANETs. In this study, we perform a comprehensive analysis of the traditional routing protocols for MANETs. Based on the analysis results, we obtained a common framework for designing routing protocols for MANETs. To visualize the efficiencies of protocols under variable network traffic, we performed a simulation to compare the performance of typical protocols, including AODV, DSR, and OLSR. The obtained results again demonstrated that on-demand-based routing protocols are suitable for dynamic topology networks. We hope that this work will be an essential guide in researching and proposing energy-saving, secure, and QoS routing protocols for MANETs in the future.

Actualmente, vivimos en una sociedad cada vez más digital, donde las Tecnologías de la Información y la Comunicación (TIC) están provocando un impacto en todos los niveles, también en el educativo. La escuela debe asumir el reto de integrar eficazmente las TIC, promoviendo situaciones enriquecidas con tecnologías en las que la metodología constituya el factor clave de los procesos de innovación educativa. La escuela rural debe hacer frente para ello a las desigualdades existentes, con el firme propósito de superarlas. Desde esta perspectiva, el artículo presenta un estudio descriptivo del uso que en las escuelas rurales de la Región de Murcia se hace de las TIC. La metodología escogida es la mixta, y la recogida de información se ha realizado a través de un cuestionario ad hoc construido para la investigación. Con los resultados obtenidos, hemos podido conocer las necesidades en la disponibilidad de recursos, y el uso didáctico que hacen de las TIC los docentes de los colegios rurales agrupados (CRA) en la Región de Murcia, constatando que aún les cuesta dejar atrás metodologías tradicionales para dar paso a la innovación educativa, a través de tecnologías emergentes. Today, we live in an increasingly digital society, where Information and Communication Technologies (ICT) are causing an impact at all ranges, in the educative even. The school must take on the challenge of effectively integrating ICT, promoting situations enriched with technologies in which methodology was the key factor in educational innovation processes. Rural schools must take up this challenge, assuming existing inequalities, but with the firm intention of overcoming them. From this perspective, the article presents a descriptive study of the use of ICT in rural schools in the Region of Murcia. The methodology chosen is mixed, and the collection of information has been carried out through an ad hoc questionnaire constructed for research. From the analysis of data, we have been able to know the needs in the availability of resources, and the didactic use that the teachers of the rural schools grouped together in the Region of Murcia make of the ICT, confirming that it is still difficult for them to leave behind traditional methodologies to give way to the educational innovation, through emerging technologies.

Disaster Scenario

Much work is underway within the broad next generation technologies community on issues associated with the development of services to support interdisciplinary domains. Disaster reduction and emergency management are domains in which utilization of advanced information and communication technologies (ICT) are critical for sustainable development and livelihoods. In this article, the authors aim to use an exemplar occupational disaster scenario in which advanced ICT utilization could present emergency managers with some collective computational intelligence in order to prioritize their decision making. To achieve this, they adapt concepts and practices from various next generation technologies including ad-hoc mobile networks, Web 2.0, wireless sensors, crowd sourcing and situated computing. On the implementation side, the authors developed a data mashup map, which highlights the criticality of victims at a location of interest. With this in mind, the article describes the service architecture in the form of data and process flows, its implementation and some simulation results.
