Acta Universitatis Danubius : Oeconomica , 2011,
Abstract: Computer crime, also referred as cyber-crime, is considered today one of the main leadingproblems in the ongoing global economic crisis and an impediment in the development of manycountries. Objectives of this work are: to determine the evolution of cyber-crime during the currenteconomic crisis, to emphasize the severity of this problem and the urgent need to limit its impactworldwide, to determine consumers perceptions regarding this phenomenon in Romania. Prior Workrelated to this issue was conducted by the Computer Security Institute in United States, InternationalComputer Protection Agency, Symantec and Ponemon Institute. In their studies, these institutionshave revealed many of cyber-crime features and proposed valuable solutions for decreasing itsimpact. The Approach used in this paper was a survey among Romanian consumers regarding cybercrime.A total number of 110 respondents participated in this survey. Results showed that almost80% of respondents were victims of cyber-crime at least once and more than 87% of respondentsnever reported these crimes to the police. As regards Implications, the study can offer support tospecialized institutions, while academics can use these findings for further research. The Value of thispaper consists of relevant findings regarding cyber-crime issue in Romania.

Abstract: Olive growers need relevant information about economic justifications of their investments in the construction of new olive groves, and about economic effects of olive growing. In that context, the purpose of the research is the analysis of an investment in olive grove establishment and of the economic indicators of production of olives in full growth. The purpose is to establish the economic justification of investments in the olive groves establishment, and to establish the economic effectiveness of olive growing. In the course of work, the method of simulation modeling was applied. For the purpose of the research, a deterministic simulation model was constructed, consisting of a sub-model of olive grove establishment, and a sub-model of olive growing. Total investment value of 1 hectare of olive grove establishment amounts to65,500 kn. Profit evaluation indicates that investment of 1 hectare of olive grove establishment is economically justifiable. An olive grove, 1 hectare large, in one year of full yield, makes a profit in the amount of 34,751 kn, and the olive grower has to evaluate if the economic results satisfy his expectations for the work he put in.
Growing dynamics of Internet providers  [PDF]

Physics , 2001, DOI: 10.1103/PhysRevE.64.035105
Abstract: In this paper we present a model for the growth and evolution of Internet providers. The model reproduces the data observed for the Internet connection as probed by tracing routes from different computers. This problem represents a paramount case of study for growth processes in general, but can also help in the understanding the properties of the Net. Our main result is that this network can be reproduced by a self-organized interaction between users and providers that can rearrange in time. This model can then be considered as a prototype model for the class of phenomena of aggregation process in social networks.
Internet, Economic Growth and Recession  [PDF]

Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.43A023

This paper investigates the impact of internet on economic growth and this impact during the recession. The data are drawn from World Bank in a panel of 201 countries from 1988 to 2010. Results from an OLS model reveal that a 10 percentage point increase in internet penetration rate raises real GDP per capita by 0.57 to 0.63 percentage points. During the recession relative to expansion, the coefficient of internet reduces but it still remains statistically positive. This suggests that internet provides a way to solve the problem of economic recession. Our results are robust to the inclusion of time and country fixed effects.

Abstract: Background. The internet offers a potential for improving patient knowledge, and e-mail may be used in patient communication with providers. However, barriers to internet and e-mail use, such as low health literacy and cognitive impairment, may prevent patients from using technological resources. Purpose. We investigated whether health literacy, heart failure knowledge, and cognitive function were related to internet and e-mail use in older adults with heart failure (HF). Methods. Older adults ( ) with heart failure ( years) completed measures of health literacy, heart failure knowledge, cognitive functioning, and internet use in a cross-sectional study. Results. Internet and e-mail use were reported in 78.2% and 71.4% of this sample of patients with HF, respectively. Controlling for age and education, logistic regression analyses indicated that higher health literacy predicted e-mail ( ) but not internet use. Global cognitive function predicted e-mail ( ) but not internet use. Only 45% used the Internet to obtain information on HF and internet use was not associated with greater HF knowledge. Conclusions. The majority of HF patients use the internet and e-mail, but poor health literacy and cognitive impairment may prevent some patients from accessing these resources. Future studies that examine specific internet and email interventions to increase HF knowledge are needed. 1. Introduction Healthcare is experiencing a push towards the increasing use of electronic communication. The Health Information Technology for Economic and Clinical Health Act enables providers to receive incentive payments for transitioning to electronic medical records [1]. Allowing patient access to medical records electronically offers the potential to improve health outcomes [2, 3]. For example, electronic portals enable patients to securely communicate with their physician, request medication refills, and view lab results [4]. Electronic resources such as patient portals may even assist patients in disease self-management by tracking refill history and changes in health status. However, adoption has been limited. Although growing in popularity, only 7% of Americans utilize patient portals [5]. However, internet use among older adults is increasing. In 2005, approximately 30% of adults aged 65 and older reported ever using internet or e-mail, and only 46% of those who used the internet reported daily internet use [6]. More recent estimates suggest that 53% of American adults aged 65 and older report internet or e-mail use and that 70% of those regularly use the internet [7]. As
"Internet +", Inclusive Finance and Economic Growth--Empirical test of PVAR model based on Panel Data

- , 2017,
Abstract: 运用多元测算方法和主成分分析法获取我国31个地区2008-2014年“互联网+”、普惠金融和经济增长相关变量数据,借助面板向量自回归模型(PVAR)研究三类变量间的动态关系,实证研究发现:“互联网+”和普惠金融对经济增长的影响程度相当,经济增长对“互联网+”的影响较大,而对普惠金融影响相对较小。微观上看,三者之间正向作用已经存在,普惠金融对城镇化率和贸易开放度驱动的经济增长具有正向促进作用,“互联网+”对普惠金融发展、城镇化率和贸易开放度驱动的经济增长也具有正向促进作用,因此,需要各经济主体加强基础性投入、注重精准化投入并做到长期坚持以促进三者协同发展。但从长期看,普惠金融对“互联网+”和经济增长率和居民消费价格指数驱动的经济增长存在负面冲击,“互联网+”对经济增长率和居民消费价格指数驱动的经济增长也具有微弱的负面冲击,因此,需要政府层面加强统一监管并积极理顺三者之间的关系,以消除其中的摩擦因素。
The paper use multiple calculation method and principal component analysis to obtain the "Internet plus", inclusive financial and economic growth related variables of 31 regions in China during 2008-2014, using panel vector autoregressive model (PVAR). The study found that the dynamic relationship between innovative research of three kinds of variables between the empirical: "Internet plus" and inclusive financial impact on economic growth, the economic growth effect of the "Internet plus" large and relatively small impact on financial inclusion; between the microscopic point of view the three positive effect already exists, the urbanization rate of Inclusive Finance and the opening degree of trade driven economic growth, "Internet plus" of inclusive financial development and urbanization rate and the opening degree of trade driven economic growth has a positive role So, the need to consider the various economic entities from a strong foundation, precision investment and long-term adherence to consider three collaborative development; but from the long-term development considerations, there are still some negative friction, inclusive finance "Internet plus" and the economic growth rate and consumer price index driven economic growth, Internet plus for the economy the growth rate and consumer price index driven economic growth also has a negative impact on the weak situation, need the government to strengthen the unified supervision and actively improve the lubrication and eliminate friction factors among them.
On the Evolution of the Internet Economic Ecosystem  [PDF]

Computer Science , 2012,
Abstract: The evolution of the Internet has manifested itself in many ways: the traffic characteristics, the interconnection topologies and the business relationships among the autonomous components. It is important to understand why (and how) this evolution came about, and how the interplay of these dynamics may affect future evolution and services. We propose a network aware, macroscopic model that captures the characteristics and interactions of the application and network providers, and show how it leads to a market equilibrium of the ecosystem. By analyzing the driving forces and the dynamics of the market equilibrium, we obtain some fundamental understandings of the cause and effect of the Internet evolution, which explain why some historical and recent evolutions have happened. Furthermore, by projecting the likely future evolutions, our model can help application and network providers to make informed business decisions so as to succeed in this competitive ecosystem.
Dynamic view of the nuclear matrix.

Acta Medica Okayama , 2005,
Abstract: The nuclear matrix is an operationally defined nuclear skeletal structure that is believed to be involved in many nuclear functions including DNA replication, transcription, repair, and prem RNA processing/transport. Until relatively recently, the nuclear matrix was thought to be a rigid and static structure, but it is now thought to be dynamic. This paradigm shift was based in part on the tracking of the intranuclear movement of proteins tagged with fluorochromes. In this review, we attempt to redefine the nuclear matrix in light of recent findings and describe some useful techniques for the dynamic analysis of nuclear function.
A Dynamic View of Circular Colorings  [PDF]

Mathematics , 2006,
Abstract: The main contributions of this paper are three-fold. First, we use a dynamic approach based on Reiter's pioneering work on Karp-Miller computation graphs to give a new and short proof of Mohar's Minty-type Theorem. Second, we bridge circular colorings and discrete event dynamic systems to show that the Barbosa and Gafni's results on circular chromatic number can be generalized to edge-weighted symmetric directed graphs. Third, we use the above-mentioned dynamic view of circular colorings to construct new improved lower bounds on the circular chromatic number of a graph. We show as an example that the circular chromatic number of the line graph of the Petersen graph can be determined very easily by using these bounds.
A Methodological Framework Based on the Dynamic-Evolutionary View of Heritage  [PDF]

Sustainability , 2013, DOI: 10.3390/su5093992
Abstract: The paper describes the shifting perspective from the contemplative view to the dynamic-evolutionary view of heritage and the main characteristics of the resulting multi-criterial decision-aid tool for the evaluation of heritage. With the integration of conservation in planning processes and with opening of the procedures to public participation, there is a need for decision-aid tools that can help increase rationality and transparency in decision-making processes related to planning. By understanding the contemporary view of heritage and the landscape, it is possible to create tools capable of accounting for spatial complexity and the extant cultural, social, historic and economic relations. With this in mind, a specific tool was created that can be used for the analysis, diagnosis, evaluation and monitoring of spatial heritage (registered and under consideration for protection), identifying opportunities, defining strategies for heritage management processes, and in the creation and evaluation of development and management scenarios. The paper illustrates a shift in the consideration of heritage in spatial planning and presents an application of the developed model in a case study.
