“…Las redes sociales permiten a los internautas compartir y discutir datos, en ellas se publica información multimedial (texto, audio, video e imagen) (Cortizo, Carrero, & Gómez, 2011). Las más utilizadas actualmente son Twitter que cuenta con 320 millones de usuarios activos y se encuentra en más de 35 idiomas (Twitter, 2016), Facebook con 1650 millones de usuarios en 110 idiomas (Facebook, 2016), Instagram con 300 millones de usuarios que publican aproximadamente 60 millones de fotos cada día (Instagram, 2016) y YouTube con mil millones de usuarios que se encuentra disponible en 76 idiomas (YouTube, 2016).…”

ResumenEl objetivo de la presente investigación es analizar la influencia de las valoraciones de los hoteles en las redes sociales y cómo estas afectan los ingresos de los hoteles. A partir de los datos mensuales (entre agosto de 2014 y julio de 2015) de 48 hoteles de Colombia, Ecuador y Perú se analizaron principalmente las variables: GRI (Global Review Index), Oferta, Demanda, Venta, RevPAR (Revenue Per Avalable Room) y Ubicación; mediante análisis de conglomerados y un modelo lineal. Se encontró que un mejor GRI favorece a una mejor ratio entre las ventas y la oferta. En concreto, observamos que cuando el GRI se incrementa en una unidad, el RevPAR crece en 0,49%, manteniendo el resto de variables constantes. Es la primera investigación realizada en Sudamérica para analizar la incidencia de las redes sociales en los ingresos de los hoteles.

“…In this paper, we model and explore using simulation, the effect of users joining and leaving a social network, to understand how a critical mass affects both the success and failure of a social media platform. Social networks are of increasing importance to social science (Willer, ; Centola, ; Roca et al ., ) and to electronic commerce research in particular (Cortizo et al ., ; Liang and Turban, ) as services such as Facebook and Twitter have opened avenues for new business models (Liang et al ., ) something referred to as social commerce (Stephen and Toubia, ). According to a recent special issue on the topic, social commerce raises a variety of new questions for e‐commerce researchers and the field could become one of the most challenging research arenas in the coming decade (Liang and Turban, ).…”

Using simulation, this study compares a critical mass of adopters with a critical mass of those who discontinue their adoption of social media. A network of reflex agents is simulated where each agent has an unchanging threshold and will adopt social media if the number of their friends who have adopted is greater than it. In the first study, the size of the critical mass that adopts is varied, and in the second, the size of the critical mass that discontinues use is varied. The studies show that a critical mass of leavers can cause a community to fail and that this mass can potentially be as small as that needed to influence a community to succeed; although given a certain critical mass, their leaving is less likely to cause failure than their adoption is success. This influence of the critical mass is facilitated by network structure.

“…The data residing on the service provider is not protected by this mechanism. There are also parallel approaches to OAuth such as Facebook's extensions to the OAuth protocol in the form of OAuth 2.0 [9], Google's FriendConnect [3] and MySpace's alternative called MySpaceID [23]. However, to the best of our knowledge, there is Algorithm 1 Sample Java code for unbinding data using JSR321 1: try { 2:…”

Smartphones are increasing in popularity and it is widely believed that their market share will continue to rise in the future. Due to the limited capabilities of smartphones compared to the PC, webbased services accessed through native applications are quickly becoming the de-facto standard on these devices. Allowing secure access to data residing on web-based services is a hot security issue targeted by many protocols. OAuth is the most popular of these and is in use by a vast majority of industry leaders. However, it suffers from some limitations the primary of which is that once a resource consumer is authorized access to a web service, it can access the data residing on that service from anywhere and at any time. This leads to severe privacy concerns. In this paper, we propose extensions to the core OAuth protocol that cater to this problem by introducing the concept of device-specific authorization using the constructs of Trusted Computing. We provide the details of our proposed protocol and describe the proof-of-concept developed to demonstrate the feasibility of our approach. The end results is a light-weight, user-friendly protocol that provides device-specific authorization for smartphones thus enhancing privacy without sacrificing the simplicity of the core OAuth protocol.
