Mobile Internet : perspectives from the Stakeholders

Mobile internet represents a major new trend in communication technologies use and consumption, but few evidence exists that confirms claims of novelty and social change in association with this technology use. This paper characterizes the use of mobile internet in a southern European country and associated patterns of use, focusing both on users’ profiles, forms of access, motivations to use and most popular activities undertaken via this technology, from a diffusion of innovations and social adoption of technologies perspectives, and tries to compare mobile it with fixed access to the internet in order to validate possible transformations that point to new social configurations. We seek to understand the way stakeholders perceive and characterize the European context of mobile internet. The depicted study involved a qualitative stage consisting of a set of interviews with mobile communications industry representatives and market research community in the country. These interviews were analysed in Nvivo, leading to the following eleven main categories that are explored throughout the paper: smartphones in Europe, mobile internet in Europe, users profiles, obstacles to the spread, forms of access, forms of use, motivations to use mobile internet, limitations of smartphones, apps, digital divide VS digital union and predictions for the future, as well as several subcategories forming a tree categorization. According to the data collected, mobile phones’ sales are decreasing in Europe and worldwide but on the other hand smartphones are having an exponential growth which leads to the democratization of internet access via mobile devices. As a consequence of this, it is believed that mobile internet access will soon exceed the fixed one. Mobile internet users are multiplatform, they exploit all the possibilities of mobility and they are spending less time on computers. The main obstacles to the spread of mobile internet are the high prices of price plans and there is still a lack of information and knowledge regarding the service. Mobile internet users are developing new online surfing behaviours based on apps and less in browsers and social networks represent a very high share of internet traffic through mobile phones. With mobility, “dead time” is turning into useful time and users are more likely to be available to try new services and analyze products. Innovative services concerning geolocation, consumerism, share and relationships are growing and it is necessary to highlight that mobile internet allows calling and texting, which can turn telecommunications companies into the role of Dump Pipes. This exploratory design raises questions in relation with mobile internet access and its social consequences, and provides interesting indicative research results relevant for future research in this area.

EU-Russia energy diplomacy: The need for an active strategic partnership. EU Diplomacy Paper 4/2012, July 2012

This paper explains the conflictive and cooperative elements of energy diplomacy between the European Union (EU) and Russia. It argues that interdependence forms the underlying principle of this relationship and creates both sensitivity and vulnerability for the interdependent parties, thus carrying the sperms of both conflict and cooperation. Both sides would be negatively affected by the other side’s noncooperation within the current policy framework and the prevailing mistrust and recurring tensions can be explained by this sensitivity. However, even if both sides’ policies were adjusted, vulnerability interdependence would still prevent them from seriously reducing their energy cooperation. It is necessary then to see how EU and Russian energy diplomacy can converge and how their strategic energy partnership can be cemented.

Mobile Incubation in Waved Albatross (Phoebastria irrorata): Associated Hatching Failure and Artificial Mitigation

Waved albatrosses often relocate their eggs during incubation by placing the egg between the tarsi and shuffling forward. This behavior frequently results in eggs becoming lodged between rocks, accounting for at least 10%, and perhaps as much as 80%, of breeding failures. Because albatross populations worldwide are currently threatened, artificial means of augmenting reproductive success may be necessary to mitigate losses caused by anthropogenic effects. We characterize the frequency and extent of egg movement; test several hypotheses related to microhabitat, timing, and incubation location to explain the behavior; and investigate the utility of repositioning lodged eggs in a location in which breeding birds might resume incubation. Egg rescue increased both the likelihood of continued incubation as well as the hatching rate in our experiment, and provides an efficient, low-cost management option for this species.

Architecture for Living Neuronal Network Control of a mobile robot

The intelligent controlling mechanism of a typical mobile robot is usually a computer system. Research is however now ongoing in which biological neural networks are being cultured and trained to act as the brain of an interactive real world robot – thereby either completely replacing or operating in a cooperative fashion with a computer system. Studying such neural systems can give a distinct insight into biological neural structures and therefore such research has immediate medical implications. The principal aims of the present research are to assess the computational and learning capacity of dissociated cultured neuronal networks with a view to advancing network level processing of artificial neural networks. This will be approached by the creation of an artificial hybrid system (animat) involving closed loop control of a mobile robot by a dissociated culture of rat neurons. This paper details the components of the overall animat closed loop system architecture and reports on the evaluation of the results from preliminary real-life and simulated robot experiments.

The indoor localization system using vision for multiple mobile robots

This paper presents the development of an indoor localization system using camera vision. The localization system has a capability to determine 2D coordinate (x, y) for a team of mobile robots, Miabot. The experimental results show that the system outperforms our existing sonar localizer both in accuracy and a precision.

Long-term change, interannual and intra-seasonal variability in climate and glacier mass balance in the Central Greater Caucasus, Russia

Long-term trends, interannual and intra-seasonal variability in the mass-balance record from Djankuat glacier, central Greater Caucasus, Russia, are related to local climate change, synoptic and large-scale anomalies in atmospheric circulation. A clear warming signal emerged in the central Greater Caucasus in the early 1990s, leading to a strong increase in ablation. In the absence of a compensating change in winter accumulation, the net mass balance of Djankuat has declined. The highest value of seasonal ablation on record was registered in the summer of 2000. At the beginning of the 21st century these trends reversed. Ablation was below average even in the summer of 2003, which was unusually warm in western Europe. Precipitation and winter accumulation were high, allowing for a partial recovery of net mass balance. The interannual variability in the components of mass balance is weakly related to the North Atlantic Oscillation (NAO) and the Scandinavian teleconnection patterns, but there is a clear link with the large-scale circulation anomalies represented by the Rossby pattern. Five synoptic categories have been identified for the ablation season of 2005, revealing a strong separation between components of radiation budget, air temperature and daily melt. Air temperature is the main control over melt. The highest values of daily ablation are related to the strongly positive NAO which forces high net radiation, and to the warm and moist advection from the Black Sea.

Interactions between mass balance, atmospheric circulation, and recent climate change on the Djankuat Glacier, Caucasus Mountains, Russia

This paper reports recent changes in the mass balance record from the Djankuat Glacier, central greater Caucasus, Russia, and investigates possible relationships between the components of mass balance, local climate, and distant atmospheric forcing. The results clearly show that a strong warming signal has emerged in the central greater Caucasus, particularly since the 1993/1994 mass balance year, and this has led to a significant increase in the summer ablation of Djankuat. At the same time, there has been no compensating consistent increase in winter precipitation and accumulation leading to the strong net loss of mass and increase in glacier runoff. Interannual variability in ablation and accumulation is partly associated with certain major patterns of Northern Hemisphere climatic variability. The positive phase of the North Pacific (NP) teleconnection pattern forces negative geopotential height and temperature anomalies over the Caucasus in summer and results in reduced summer melt, such as in the early 1990s, when positive NP extremes resulted in a temporary decline in ablation rates. The positive phase of the NP is related to El Nino-Southern Oscillation, and it is possible that a teleconnection between the tropical Pacific sea surface temperatures and summer air temperatures in the Caucasus is bridged through the NP pattern. More recently, the NP pattern was predominantly negative, and this distant moderating forcing on summer ablation in the Caucasus was absent. Statistically significant correlations are observed between accumulation and the Scandinavian (SCA) teleconnection pattern. The frequent occurrence of the positive SCA phase at the beginning of accumulation season results in lower than average snowfall and reduced accumulation. The relationship between the North Atlantic Oscillation (NAO), Arctic Oscillation, and accumulation is weak, although positive precipitation anomalies in the winter months are associated with the negative phase of the NAO. A stronger positive correlation is observed between accumulation on Djankuat and geopotential height over the Bay of Biscay unrelated to the established modes of the Northern Hemisphere climatic variability. These results imply that the mass balance of Djankuat is sensitive to the natural variability in the climate system. Distant forcing, however, explains only 16% of the variance in the ablation record and cannot fully explain the recent increase in ablation and negative mass balance.
