scholarly journals Virtualization Effects on The Security

Virtualization is a technology which provides the efficient and effective usage of computing system .the computing system is not only a single personnel system but also a system consisting of multiprocessors systems. To use the system efficiently & effectively. We will be using virtualization technology .now a days business world is very competitive .customers demanding for new products this technology will provide opportunity to produce new products with the same resources with the existing infra structure. Within this technology one important issue is the "security”. It has changed the classical definition of security. The classical definition suggest that try to detect the security violations at the first place and then take the action but with the virtualization we can create the separate environment for security related application that would not effect the trusted information with the system .The concept has change the scenario of security related solutions by inviting the malicious from the communication system & executing them with the separate virtualization machine environment that would not affect the trusted information with the same system

Background:Reactive arthritis (ReA) is defined by 1999 ACR criteria as arthritis preceding a bacterial genitourinary (GUS) or gastrointestinal (GIS) infection in 3 days-6 weeks and evidence of triggering infection. Recently, ReA is classified as SpA and patients who do not fulfill SpA criteria are classified as undifferentiated spondyloarthritis (USpA) according to ASAS/EULAR SpA classification criteria.Objectives:In several case reports which are associated with other infective agents are reported and the definition is extended for some clinicians so that SpA which is occurred after any infection is called as ReA. On the other hand, some researchers still accept the classical definition of ReA. The problem with the heterogeneity of opinions and unstandardized definition of ReA hinders studies about pathogenesis and standardization of treatments. In this study, we aimed to determine the spectrum of the use of the definition of reactive arthritis in publications in PubMed between 2009-2019.Methods:The ReA keyword is searched in PubMed for the years between 2009-2019. 248 different publications have been identified and included in this research. 89 articles, 47 reviews, 108 case reports, 2 guidelines, and 2 editorials reviewed for the definition of ReA.Results:Only 42.7% (106 patients) of these publications meet the classical definition which suggests ReA after only GIS and GUS infections. In 4 (1.6%) of the publications ReA was defined after GIS, GUS and oropharyngeal infections; in 3 (1,2%) of the publications after any bacterial infection; in 9 (3.6%) of the publications after any infection. In 8 (3.2%) of the publications, ReA and USPA was used correspondingly. In 39 (15,7%) of the publications the term agent related, ReA was used without making a general definition for ReA. 79 publications (31,9%) have not defined ReA.According to causative agent and ReA relationship, in 64 (24,6%) general infective agents, in 75 (30,2%) classical agents, in 22 (8,9%) other bacterial agents, in 23 (9,3%) streptococcus, in 10(4%) intravesical BCG, in 6 (2.4%) HIV, in 6 (2.4%) tuberculosis, in 12 (4,8%) clostrudium difficle, in 2 (0.8%) parasites were reported. In 31 (12,5%) of the publications the causative agent for the ReA was unknown, the diagnosis was made clinically.Conclusion:In this study, it is aimed to draw attention terminology intricacy and the need for the standardization of the definition of ReA and USpA. It is clear that to standardize the definition of Rea and USpA is necessary. Between 2009-2019 there are reported cases diagnosed as ReA associated with bacterial infections (especially with Clostridium difficile, streptococcus and tuberculosis infections), and viral infections (by a majority with HIV), and parasitic infections. It is not clear if we need to define them classically or define them as USPA. Another important consideration is the necessity of extended laboratory investigations to find out the real causative agent even if the patient is clinically diagnosed with ReA. The requirement of the differentiation between ReA and USpA must be revealed for therapeutic researches.References:[1]A proposal for the classification of patients for clinical and experimental studies on reactive arthritis.

Abstract The present paper suggests that the recurring appeal to kinship diplomacy undermines a fixed idea of ‘nation’ in Archaic Greece, especially in the first two decades of the fifth century BC. It aims to present a series of test cases in Herodotus that explain why contemporary patterns and theories on ancient ethnicity can hardly explain the totality of the historical spectrum. Blood ties could sometimes fortify ethnic relationships, as in the case of Aristagoras’ mission to Sparta (Hdt. 5.49.3), since the common Greekness could elicit the Spartan to help to the Ionians. In other times, the same blood ties were applied to divine genealogies, and they could also be used to show the feeble devotion of cities like Argos to the Greek cause (7.150.2: Xerxes expects the Argives to join the Persian cause, since they descend from Perses). Habits and traditions, often taken as indicia of national feeling, could be thought of as clues of ancient migrations (so the Trojans became Maxyes in Lybia: 4.191). Even language might not help in justifying ethnic relationships: for instance, the Greeks living in the Scythian Gelonus spoke a mixed language (4.108). These few case studies may shed a different light on the classical definition of Greekness (to hellenikon) in terms of blood, language, cults, and habits, all given by Herodotus (8.144). Far from being a valid label for all the Greeks of the fifth century, this statement owes much to a specific variety of the language of kinship diplomacy. The final section argues for the opportunity to avoid the later and misleading idea of nation when studying Herodotus and the age of the Persian Wars, which are instead characterized by various and contrasting strategies. Greek groups and ethne can be better described as networks of lightly defined communities.

Dust storm episodes at the aerodromes in the Asian part of Russia / Ivanova A.R., Skriptunova E.N., Komasko N.I., Zavialova A.A.// Hydrometeorological Research and Forecasting, 2021, no. 2 (380), pp. 20-42. According to 2001-2020 METAR data, episodes of dust storms at 26 international aerodromes in the Asian Russia causing poor visibility are studied. The conditions for issuing reports on dust storms, their correspondence to the definition of a dust storm are discussed. It was found that out of 337 reports describing dust transport by strong wind, only 7 episodes registered at the aerodromes of Irkutsk, Abakan, Omsk, and Blagoveshchensk corresponded to the classical definition. The others detected at 15 of 26 aerodromes may be defined as “dust events” – the episodes of dust transfer causing the nonessential visibility reduction. The seasonal variation in such episodes and its connection with changes in visibility are studied. The characteristics of dusty air masses and the direction of their advection are given. Keywords: dust storm, dust events, aerodromes of Asian Russia, seasonal variation, trajectory analysis

This chapter is to define the firm’s innovative core and create frameworks to integrate innovation throughout the management of knowledge by generating implementing ideas, strategies and plans applied that cultivate a thinking organization aims to associate innovation with business targets. It argues that companies which manage and transform the knowledge effectively reap the rewards of scientific and technological achievement in order to adopt innovation concept in their operation. Furthermore, the author hope that firms understanding the information received from the current global business world and transmit it to reap the rewards of scientific achievement will increase their competitiveness competition not only for sales, but also for technical know – how and skills. At the company level depends on the speed with which new products can be brought to the market place and on the importance of achieving new cost – saving improvements.

According to Alfred Tarski’s classical definition, logical consequence is necessary and formal. This paper focuses on the question: In what sense (if any) is material consequence a logical relation? For Tarski, material consequence has no modal force. Treating all terms (of a language with a fixed domain) as logical, he reduces logical consequence to material consequence. Thus, Tarskian material consequence seems to be a logical oxymoron designed to emphasize the importance of the distinction between logical and extra-logical terms for the definition of logical consequence. Historically, however, there have been different approaches to material consequences. This paper attempts to provide an investigation into the parallels between Tarski’s dichotomy of formal and material consequence and the modern

Purpose This paper aims to examine the impact of predictive gamification, through a sales simulator game, as a strategy to minimize sales problems in organizations. Design/methodology/approach This empirical study was executed in a large global company that produces and markets footwear for B2B and B2C markets. The company operates in more than 18 countries and adopts the gamification to train 7,600 sellers and 10,052 professionals directly linked to the sales area. The methodology adopted followed a qualitative and exploratory approach based on an in-depth case study analysis. Findings Results indicated that the use of predictive gamification allowed mitigating future problems, in average, four months in advance of the arrival of the new products at the points of sale. The main findings included improvement in sales arguments, product knowledge and sales closure. The company assigns the results to the implementation of the gamification and the possibility to simulate the evaluation of the level of readiness of the sales force resources. For this, the following three primary variables emerged: adequate definition of training content, analysis of the learning process and simulation of store reality. Research limitations/implications The authors introduced to the sales training literature the concept of predictive gamification. The predictive gamification allows anticipating and reducing future problems before the arrival of the new products in the market, improving the argument of sales, the knowledge about the products and the ratio of sales conversion of stores. Practical implications First, the content design of gamification needs to be carefully projected before the simulator development, considering the target audience and its particularities. Second, the construction of evaluation activities needs to consider contexts, actions and results. Third, monitoring the paths taken by the seller in the simulator environment is requisite. Fourth, the analysis of the results of vendor responses in the simulator environment can be obtained through learning management system reports. Fifth, the development of game simulators with advanced technologies may be done with low investment. Originality/value The findings have implications for the field vis-à-vis three main research gaps identified in the literature discussing gamification in sales training. First, the authors identified best practices from the application of gamification in sales training. Second, they showed the sales qualification processes, which can be improved by applying gamification. Third, they presented strategies of use of gamification as an approach allied to the training of sales professionals to generate enhanced sales results.

The main contribution of this paper is the introduction of an intrinsic definition of the connective “fuzzy exclusive or” E (f-Xor E), based only on the properties of boundary conditions, commutativity and partial isotonicity-antitonicity on the the end-points of the unit interval U = [0,1], in a way that the classical definition of the boolean Xor is preserved. We show three classes of the f-Xor E that can be also obtained from the composition of fuzzy connectives, namely, triangular norms, triangular conorms and fuzzy negations. A discussion about extra properties satisfied by the f-Xor E is presented. Additionally, the paper introduces a class of fuzzy equivalences that generalizes the Fodor and Roubens's fuzzy equivalence, and four classes of fuzzy implications induced by the f-Xor E, discussing their main properties. The relationships between those classes of fuzzy implications and automorphisms are explored. The action of automorphisms on f-Xor E is analyzed.
