Since 2009, ransomware has plagued computer users. By analysing ransomware's communication with its controller, researchers have found out patterns used in naming the controller's domain. These names are generated by a Domain Generation Algorithm (DGA). It has been proposed that DGA generated domain names appear more random than actual domains registered for a legitimate purpose. If this was the case, we could block communication to such domains. In this paper, we analyse the feasibility of detecting DGA generated domain names based on their randomness. We compare a large (800 000) list of actual DGA domain names with (i) a list of most popular domains in the internet and (ii) a list of actual queries to a domain name service. Unfortunately, it seems very difficult to block communication with apparently random domain names. Though some DGA generated names are apparently random, the perceived randomness of both popular domain names and actual queried names is often greater than that of DGA domains.

Facebook is one of the largest socializing networks nowadays, gathering among his users a whole array of persons from all over the world, with a diversified background, culture, opinions, age and so on. Here is the meeting point for friends (both real and virtual), acquaintances, colleagues, team-mates, class-mates, co-workers, etc. Also, here is the land where the information is spreading so fast and where you can easily exchange your opinions, feelings, traveling informations, ideas, etc. But what happens when one is reading the news feed or is seeing his Facebook friends’ photos? Is he thrilled, excited? Is he feeling that the life is good? Or contrary: he is feeling lonely, isolated? Is he doing a comparison with his friends? These are some of the questions this paper in trying to answer and shaping some of these relationships, the grey system theory will be used. © Springer International Publishing Switzerland 2014.

The paper analyses the predictive power of heterogeneous agents interacting in an evolutionary agent-based model of the stock market when simulated through Altreva Adaptive Modeler multi-agent simulation software application. The paper tests the long-term prediction accuracy of an evolutionary agent-based model when simulating the S&P500 stock market index. The model incorporates 2,000 agents which trade amongst each other on an artificial stock market which uses a double auction trading mechanism. Within the evolutionary agent-based model, the population of agents is continuously adapting and evolving by using genetic programming in order to obtain new agents with better trading strategies generated from combining the trading strategies of the best performing agents and thus replacing the agents which have the worst performing trading strategies. © 2014 Springer International Publishing Switzerland.

Mobile phones are the primary way of accessing the Internet, chat, and social media in Thailand. The country is now in the midst of transitioning from the 3G network for mobile phones, with emphasis on voice calls, text messaging and slow Internet, to 4G, which is based on Mobile IP with higher speeds which makes it more suitable for all Internet use, especially video, while maintaining interoperability with the 3G network. 4G subscriptions are generally more expensive than 3G subscriptions and often require the purchase of a new mobile phone to take advantage of the new features. In this work, we explore factors that influence the intention to use 4G and use the Technology Acceptance Model (TAM) to assess the perceived usefulness (PU) and the perceived ease of use (PEU).

Twitter messages, also known as tweets, are increasingly used by marketers worldwide to determine consumer sentiments towards brands, products or events. Currently, most existing approaches used for social networks sentiment analysis only extract simple feedbacks in terms of positive and negative perception. In this paper, TweetOntoSense is proposed - a semantic based approach that uses ontologies in order to infer the actual user’s emotions. The extracted sentiments are described using a WordNet enriched emotional categories ontology. Thus, feelings such as happiness, affection, surprise, anger, sadness, etc. are put forth. Moreover, compared to existing approaches, TweetOntoSense also takes into consideration the fact that a single tweet message might express several, rather than a single emotion. A case study on Twitter is performed, also showing this approach’s practical applicability. © Springer International Publishing Switzerland 2014.

The aim of this research is to explore the motives behind the adoption or rejection of Electronic Health Records (EHR) systems in the USA by medical offices. The current health care system in the United States suffers from high expenditures and poor quality. The Patient Protection and Affordable Care Act, passed in 2010, attempts to save costs and improve quality of care by offering incentives to use Electronic Health Records systems. Part of the reform by this law is dependent on the use of technology in managing patient medical and health records. The objective is to reduce redundancy and increase quality by sharing medical information amongst different health organizations like hospitals, physician offices, laboratories and clinical institutions. The success of such reform requires the participation and collaboration of all these entities and their patients. Prior research shows that adoption of Electronic Medical Records systems by hospitals and physician offices has been evident but at a rate that is slower than in other countries. Aside from financial barriers, technical, psychological, social/legal and organizational barriers exist. In order to understand the impact of those barriers on the adoption of Electronic Health Records management by small physician offices better, a five-level adoption model is presented to define the stages of diffusion of EHR systems. Fifteen consolidated barriers are mapped to each adoption level. This research concentrates on smaller physician offices because hospitals and larger institutions are more ready and capable of adoption, according to previous research. The Diffusion of Technology Model by Rogers, the Theory of Planned Behavior by Ajzen and Fishbein, and Davis' Technology Acceptance Model are combined and extended. This model will be used to empirically measure physicians' attitudes, knowledge, social and legal influences, subjective norm and systems' ease of use and usefulness amongst other variables. These variables are applied as mediators or moderators of the intention and decision to adopt or move into subsequent levels of adoption with the goal of seeing what drives those decisions. © 2014 IEEE.

In the current economic crisis, risk managers realized that risks can be assessed in the fairest way in their interaction with other risks. Therefore, no risk is isolated, but on the contrary, it must be regarded as part of a complex network of strongly connected risks. Looking from this perspective, in this paper, we consider the risks that may manifest in a hospital, compute and analyze the risks' degree of similarity using GSTMS 6.0. software, and then based on these degrees of similarity, create a risk network using NodeXL. Having this network, the risks' management can be improved due to the fact that each risk will be regarded as a part of the risks' network, each modify that occurs in this network, having an impact on each of the other risks.

The romanian health system is characterized by lack of transparency, poor funding, insufficient numbers of medical personnel, outdated equipment, and negligence. These risk factors are sometimes manifesting together, giving rise to correlated risks that appear in cascade, causing major losses, both financial and human. Unfortunately, most managers of health institutions in Romania show a lack of management skills and reaction to increasing risk exposure of the institutions they lead. This is explained by the fact that they are either politically appointted, or are physicians who are not specialized in hospital risk management. In this paper we present a case study describing a tragedy that happened at an important hospital in Romania, where the manifestation of several types of risks generated human and financial losses, and strongly affected the hospital reputation that has reached a critical point. How could this situation have been avoided or fixed? What are the ways of evaluating, monitoring and managing the similar risks? And could the risks be prevented in time?

With the rapid development and adoption of the online social networks (OSN), firms have become more and more involved in the social media activities. One of the main triggers of the OSN activity is the diffusion phenomena through which the information is passing easily from one user to another. In this context, firm's reputation can be affected by the grey information that is passing daily through the online environment. Therefore, using one of the newly developed theories in the field, namely the grey systems theory, the incidence of the users' activity and company's advertising in OSN on its reputation is shaped.
