The legal framework for private sector development in a transitional economy : the case of Poland
No full textThe economies of Central and Eastern Europe are in the midst of a historic transition from central planning and state ownership to development of a market-driven private sector. This transition requires comprehensive changes in"rules of the game"- including the legal framework for economic activity. A market economy presupposes a set of property rights and a system of laws or customs that allow the exchange of those rights. The legal framework in a market economy has at least three basic functions: defining the universe of property rights; setting the rules for entry into and exit from productive activities; and setting the rules of market exchange. These legal tasks are accomplished by areas of law such as: company, foreign investment, bankruptcy, contract and competition law. Poland has a rich legal tradition dating from pre-socialist times, which was suppressed but not eliminated during its forty years of socialism. This tradition is being revised as the country moves toward a private market economy. The current legal framework in Poland closely follows other continental jurisdictions and has a clear and reasonable internal logic. Many of the laws are old, but most are flexible enough to permit a wide range of modern, market-oriented activity. Property law, however, remains a"jungle". The wide discretion and general lack of precedent create tremendous legal uncertainty that is sure to hamper private sector development.Environmental Economics&Policies,Banks&Banking Reform,Municipal Housing and Land,Legal Products,Land and Real Estate Development

IoT Intrusion Detection Using Modified Random Forest Based on Double Feature Selection Methods
No full textOne of the fast-expanding technology today is the Internet of Things (IoT). It is very necessary, to protect these machines from adversaries and unwanted entry and alteration. Intrusion Detection Systems (IDS) are techniques that can be used in information systems to monitor identified threats or anomalies. The challenge that arises is that the IDS should detect attacks on time in high-speed network traffic data. This paper proposed a modified IDS in IoT environments based on hybrid feature selection techniques for the random forest that can be used to detect intrusions with high speed and good accuracy. IoTID20 dataset is used which has three target classes which are the binary class as normal or abnormal and the classes of categories and sub-categories for the binary class. The highest-ranked attributes in the dataset are selected and the others are reduced, to minimize execution time and improve accuracy, the number of trees in the random forest classifier is reduced to 20, 25, and 20 for binary, category, and sub-category respectively. The trained classifier is then tested and achieved accuracy approaches 100% for the binary target prediction, 98.7% for category and accuracy ranges from 78.1% to 95.2% for the sub-category target prediction. The proposed system is evaluated and compared with previous ones and showed its performance
Enhancement performance of random forest algorithm via one hot encoding for IoT IDS
No full textThe random forest algorithm is one of important supervised machine learning (ML) algorithms. In the present paper, the accuracy of the results of the random forest (RF) algorithm has been improved by the use of the One Hot Encoding method. The Intrusion Detection System (IDS) can be defined as a system that can predict security vulnerabilities within network traffic and is located out of range on a network infrastructure. It does not affect the efficiency of the built-in network because it analyzes a copy of the built-in traffic flow and reports results to the administrator by giving alerts. However, since IDS is a listening system only, it cannot take automatic action to prevent an attack or security vulnerability detected from infecting the system, it provides information about the source address to start the break-in, the address of the target and the type of suspected attack. The IoTID20 dataset is used to verify the improved algorithm, where this dataset is having three targets, the proposed system is compared with the state-of-art approaches and shows superiority over them

Heterogeneous and tissue-specific regulation of effector T cell responses by IFN-gamma during Plasmodium berghei ANKA infection.
No full textIFN-γ and T cells are both required for the development of experimental cerebral malaria during Plasmodium berghei ANKA infection. Surprisingly, however, the role of IFN-γ in shaping the effector CD4(+) and CD8(+) T cell response during this infection has not been examined in detail. To address this, we have compared the effector T cell responses in wild-type and IFN-γ(-/-) mice during P. berghei ANKA infection. The expansion of splenic CD4(+) and CD8(+) T cells during P. berghei ANKA infection was unaffected by the absence of IFN-γ, but the contraction phase of the T cell response was significantly attenuated. Splenic T cell activation and effector function were essentially normal in IFN-γ(-/-) mice; however, the migration to, and accumulation of, effector CD4(+) and CD8(+) T cells in the lung, liver, and brain was altered in IFN-γ(-/-) mice. Interestingly, activation and accumulation of T cells in various nonlymphoid organs was differently affected by lack of IFN-γ, suggesting that IFN-γ influences T cell effector function to varying levels in different anatomical locations. Importantly, control of splenic T cell numbers during P. berghei ANKA infection depended on active IFN-γ-dependent environmental signals--leading to T cell apoptosis--rather than upon intrinsic alterations in T cell programming. To our knowledge, this is the first study to fully investigate the role of IFN-γ in modulating T cell function during P. berghei ANKA infection and reveals that IFN-γ is required for efficient contraction of the pool of activated T cells
THE IMPACT OF HOSPITAL INFORMATION SYSTEM ON THE WORKING PROCESS OF IMAM JA’FAR SADIQ HOSPITAL, ALBORZ PROVINCE - 2016
No full textObjectives: This research has been done on the impact of the hospital information system on the staffing of Imam Jafar Sadiq Hospital in Alborz in 2016. The research method is applied and in terms of data collection method, descriptive-survey method. The statistical population consisted of all employees of contractual, design and contract personnel working in Imam Jafar Sadiq Hospital.
Methods: In this study, 384 people were selected using Cochran's formula, which were selected by available sampling method. The validity of the researcher-made questionnaire and their reliability were confirmed by Cronbach's alpha with a coefficient of above 0.7. In the descriptive statistics section, mean, standard deviation, frequency and percentage of frequency were used. In the inferential statistics, the inclination and elongation were used to determine the normality of the data.
Results: The results of one-sample T-test and Friedman indicate that the hospital information system improves the work process of the staff members of Imam Jafar Sadiq Hospital.
Conclusion: Hospital information system has the greatest impact on hospital support and administration and has had the least impact on hospital performance. It should be noted that the results are consistent with most studies performed.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
