Crystal structure of trans-dichlorido(4-nitroaniline-κN 1)(piperidine-κN)platinum(II)
2015
The packing of the title compound features N—H⋯Cl hydrogen bonds and π–π stacking interactions, which form one-dimensional chains of molecules parallel to [001] further linked via N—H⋯O interactions.
On the effects of transmit power control on the energy consumption of WiFi network cards
2009
Transmit power control has been largely proposed as a solution to improve the performance of packet radio systems in terms of increased throughput, spatial reuse and battery lifetime for mobile terminals. However, the benefits of transmit power control schemes on these different performance figures may strongly depend on the employed PHY technology and channel access mechanism. In this paper, we focus on the effects of power control on the energy consumption of WiFi network cards. By means of several experimental tests carried out under different operation conditions and modulation schemes, we try to justify why the reduction of the transmission power has a marginal effect on the overall en…
Dealing with viewers’ complaints: Role, visibility and transparency of PSB Ombudsmen in ten European countries
2017
The article shows the results of a comparative analysis of the complaints management mechanisms offered by ten European Public Service Broadcasting (PSB) systems on their corporate websites. Using a qualitative methodology, it maps the procedures and evaluates the visibility, transparency and dissemination of results. The findings show, firstly, great diversity in terms of responsible election and management, despite the converging media governance. Also noteworthy is the margin of substantial improvement in the transparency and dissemination possibilities, specially relating to the interaction offered by the digital environment. Among the ten public corporations analysed, the BBC is the be…
Crystal structure of bis(μ2-methanolato-κO:κO)hexamethylbis(μ2-triphenylacetato-κO:κO′)bis(μ2-triphenylacetato-κ2O,O′:κO)dialuminiumdilanthanum tolue…
2018
The complex [{La(Ph3CCOO)2(Me3AlOMe)}2] has an La2(μ-OCO)4 core, contains the carboxylate ligands in μ2-κ1 O:κ1 O′ bridging and μ2-κ2 O,O′:κ1 O semi-bridging coordination modes, and displays La—C interactions with the π-system of a phenyl ring.

Comparing Innovation and Social Media Strategies in Scandinavian and US Newspapers
2018
The article focuses on innovation and social media strategies in newspaper companies in the US and three Scandinavian countries (Sweden, Norway and Denmark). Many previous studies have focused on the state of journalism and media industry in single countries, although media have distinct features in different countries. Through the comparative setting, it is possible to examine the differences in media innovation strategies and study what factors affect innovation in media production, business models, sources of funding, and social media strategies. The qualitative part of the paper consists of semi-structured in-depth interviews (N = 65) with media managers and experts, which were carried …
Roles of Exogenous Technologies in Vehicle Innovation: Cases from a Japan’s Automotive Parts Manufacturing Firm
2017
This paper explores the roles of technological innovations in the growth of Japan’s motor vehicle industry, mainly from technology spillover perspective from the early 2000s to today. An empirical analysis focusing on business performances, R&D investments, and patent applications taking a noteworthy unique case in Japan was attempted. Empirical analyses on the productivity of patent to technology stock, use of exogenous technologies for their own technological innovation on its Automotive Business Unit elucidated that innovation capabilities, incorporation of exogenous technologies, and profit generation makes a virtuous cycle of continuous technological innovation. Furthermore, we fou…
A different glimpse into mobilities: On the interrelations between daily spatial mobility and social mobility
2017
We explore the link between daily spatial mobility and social mobility, taking changes in the contemporary labor market and family as examples. We propose a new theoretical approach to mobility that is defined as a productive force of social labor. Analyzing the relationship between daily spatial mobility and social mobility, we show that spatial mobility has become a strategy of compensation for the lack of social mobility. Explanations for the increase in daily spatial mobility are also provided. Lastly, we reveal how spatial mobility has the capacity to produce major social change, taking the family as an example. peerReviewed
Un témoignage sensible, la parole du chrétien selon le pape François
2016
International audience; Si le pape François montre un intérêt soutenu pour les médias afin d’informer le plus largement de l’actualité de l’Église catholique, il s’en remet à d’autres modalités pour transmettre la Parole. Le chrétien annonce le message à travers sa manière d’être chrétien ; c’est tout le sens de la notion de « témoignage » dans l’acte de dire la Parole. À partir d’un corpus de textes pontificaux du pape François, l’intention de cette réflexion est de questionner cette manière chrétienne d’être au monde, plus précisément dans l’espace public, et d’être à l’autre en explorant conjointement deux voies : (i) le soubassement sensible d’une pratique énonciative faite de comportem…
Age of Information Based URLLC-enabled UAV Wireless Communications System
2022
This paper considers an unmanned aerial vehicles (UAV) communication network, where UAV operate as an aerial mobile relay between a source and a destination of the network. To capture the “timelines” of the received information at the destination node, a new performance metric named age of information (AoI) is considered. In addition, a short packet communication scheme maintains low latency in the proposed UAV wireless communication system. The finite block-length theory investigates the performances of short packet communications scheme in the UAV-assisted wireless communications system. In this paper, the Average Age of Information (AAoI) is estimated by applying the Stochastic Hybrid Sy…
