The Impact

Cloud Gaming is a cutting-edge paradigm in the video game provision where the graphics rendering and logic are computed in the cloud. This allows a user’s thin client systems with much more limited capabilities to offer a comparable experience with traditional local and online gaming but using reduced hardware requirements. In contrast, this approach stresses the communication networks between the client and the cloud. In this context, it is necessary to know how to configure the network in order to provide service with the best quality. To that end, the present work defines a novel framework for Cloud Gaming performance evaluation. This system is implemented in a real testbed and evaluates the Cloud Gaming approach for different transport networks (Ethernet, WiFi, and LTE (Long Term Evolution)) and scenarios, automating the acquisition of the gaming metrics. From this, the impact on the overall gaming experience is analyzed identifying the main parameters involved in its performance. Hence, the future lines for Cloud Gaming QoE-based (Quality of Experience) optimization are established, this way being of configuration, a trendy paradigm in the new-generation networks, such as 4G and 5G (Fourth and Fifth Generation of Mobile Networks).

The Impact

Psychosocial stressors and social disadvantages contribute to inequalities in opportunities and outcomes. In the current paper, we use an epidemiological perspective and highlight the role stress plays on individuals by reviewing the outcomes of major stressors such as poverty and unemployment. We further analyzed the psychological and physical cost of these stressors and their long-term impact. We examined the role of universal basic income and closely looked at income experiments that were implemented in the past, in terms of their effectiveness in enhancing the community as well as individual outcomes and propose the UBI as a tool for alleviating the impact of these stressors. At a time when a major pandemic (e.g., COVID-19) threatens economic stability and health globally, we believe the UBI is relevant now, more than ever.

Campaign Advertising

Scholars agree that there has been an increase in polarization among political elites, though there continues to be debate on the extent to which polarization exists among the mass public. Still, there is general agreement that the American public has become more sorted over the past two decades, a time during which political ad volumes have increased and ads have become more negative. In this research, we explore whether there is a link between the two. We take advantage of variation in the volume and tone of political advertising across media markets to examine the link between advertising and three dependent variables: issue polarization, affective polarization, and sorting. We focus on the impact of both recent ad exposure and cumulative ad exposure across several election cycles. Ultimately, we find little impact of advertising on polarization or sorting, both overall and among subgroups of the population.

Cloudiness and range of visibility are the most significant flight conditions for aircraft. The impact of clouds and visibility on the safety of aircraft flights, especially small aircraft, cannot be overestimated. According to the Interstate Air Committee, Kazakhstan ranks second in the number of aviation disasters. The average age of a third of Kazakhstan's small aircraft is more than 30 years. Over the past few years, 14 air accidents have occurred in the Republic of Kazakhstan, 11 of them with small aircraft. In this work, we investigate long-term data on cloudiness and visibility at the most weather-favorable airfield in Balkhash, for the possibility of safe and economical flights of small aircraft and planning training flights.

The Impact

Over the past 20 years a number of simulations or models have been developed as a basis for tracking and evaluating the impact of pharmacological and other interventions in type 1 and type 2 diabetes mellitus. These models have typically tracked the natural course of these diseases generating long-term composite claims for cost-effectiveness. These claims can extend over the lifetime of the modeled patient cohort. Set against the standards of normal science, however, these claims lack credibility. The claims presented are all too often either immune to failure or are presented in a form that is non-testable. As such they fail to meet the key experimental requirements of falsification and replication. Unfortunately, there is a continuing belief that long-term or lifetime models are essential to decision-making. This is misplaced. The purpose of this review is to argue that there is a pressing need to reconsider the needs of health system decision makers and focus on modeled or simulated claims that are meaningful, testable, reportable and replicable in evaluating interventions in diabetes mellitus.   Type: Commentary

The Impact

The past two decades have witnessed a major shift towards repair of most congenital cardiac malformations during the neonatal or infant periods of life.1 Early anatomic correction or palliation, dramatic improvements in survival, and reduced morbidity due to improvements in perioperative and long-term medical management, have resulted in new populations of children that have reaped the benefits of the best care currently available for treatment of congenital cardiac disease. The impact of the congenital cardiac malformations, however, extends far beyond the walls of the hospital or clinic where we diagnose, treat, and follow our patients. The breakthrough of achieving predictable results with repair or palliation of most lesions during the neonatal and infant periods mandates us to look beyond survival, and to examine the lives our patients lead when they are outside of our care. Our purpose in this review is to discuss the measures of psychosocial outcome that are appropriate for exploration in those neonates and infants who survive cardiac surgery, to explore what is known about the psychosocial outcomes and quality of life for these patients, and what needs exist for future research.

In this paper the impact of adopting the euro in Croatia is analysed using experiences of other countries which have passed through this process in the last decade and which are comparable with Croatia in many aspects. The process of adopting a currency different from the one that has been used for more than twenty years presents a very important economic question for each country. In this period preceding to adopting the euro, there is an opportunity to analyse this process in the countries which went through it in the past. The result of this paper shows the impacts of adopting the euro in the European countries. The selected countries, which are adequate for analysing the effects of adopting the euro, are: Portugal, Ireland, Greece, Spain, Slovenia, Slovakia, Estonia, Lithuania and Latvia. These countries have been selected for different reasons. The majority of these countries have some similarities with Croatia, which are shown in this paper via relevant economic indicators. These results are significant for Croatia and show a positive influence on the Croatian market on a long-term basis. This paper is relevant and has a practical basis both for Croatia and other countries which will go through this process in the future.

Over Time

Too often, research into the health of a particular community is brief and superficial, focusing only on what is public and leaving the private health of women and children ‘foggy’. By contrast, long-term anthropology can offer access to processes taking place within a local culture of illness. Here, an account of a community’s experience of health over the past 50 years not only outlines the key changes as seen anthropologically but also shows how even close ethnography can initially miss important data. Furthermore, the impact of a researcher – both as a guest and as a source of interference – underlines how complex fieldwork can be in reality, especially if seen through the eyes of the researcher’s hosts.

Telecommunication Operators

Fourth-Generation (4G) mobile networks are based on Long-Term Evolution (LTE) technologies and are being deployed worldwide, while research on further evolution towards the Fifth Generation (5G) has been recently initiated. 5G will be featured with advanced network infrastructure sharing capabilities among different operators. Therefore, an open-source implementation of 4G/5G networks with this capability is crucial to enable early research in this area. The main contribution of this paper is the design and implementation of such a 4G/5G open-source testbed to investigate multioperator infrastructure sharing capabilities executed in virtual architectures. The proposed design and implementation enable the virtualization and sharing of some of the components of the LTE architecture. A testbed has been implemented and validated with intensive empirical experiments conducted to validate the suitability of virtualizing LTE components in virtual infrastructures (i.e., infrastructures with multitenancy sharing capabilities). The impact of the proposed technologies can lead to significant saving of both capital and operational costs for mobile telecommunication operators.
