Impacts of Ownership Structure on Systemic Risk of Listed Companies in Vietnam
The research objective of the paper is to clarify the factors influencing system risks of listed companies in Vietnam, with a focus on clarifying the relationship and quantifying the impacts of ownership structure on systemic risk of listed companies. The data used in this study included financial statements and stock price data of listed companies on the Ho Chi Minh City Stock Exchange and Hanoi Stock Exchange of Vietnam stock market in the period from 2010 to 2017. The paper used the method of estimation in establising the regression models to choose among three models: Random Effect Model, Fixed Effect Model or Pooled OLS for regression using Stata statistical software. The research results showed that state ownership and ownership by foreign investors were positively related to systemic risk, while ownership by domestic investors had a reverse relationship with systemic risk of listed companies in Vietnam. In addition, as a control variable, both company size and profitability had an effect on the systemic risk of listed companies in the research sample. Based on the research results, the authors interpreted some of the implications in order to minimize systemic risks in the operation of listed companies in Vietnam.

Research on Big Data's Prevention Technology of Financial Systemic Risk
In order to reduce the seriousness and frequency of financial systemic risk in the new era, this paper puts forward a novel big data prevention technology of financial systemic risk. With the combination of big data technology, Internet technology and cloud computing technology, this technology can monitor the financial market in real time and guard against suspicious information. The research results show that this technology realizes the close combination of big data and the financial market, reduces the cross infection of financial systemic risk, and improves the controllability of financial systemic risk.

A Time Frequency Analysis of the Systemic Risk in China
Although there have been many empirical studies about systemic risk since the financial crisis of 2008, few have analyzed the systemic risk in the time frequency domain. In this paper, based on wavelet analysis, the main time frequency characteristics of China's systemic risk, the time frequency similarity between financial institutions, the comovement and the systemic risk contagion channels are analyzed. We find that the systemic risk rose in the short run but fell in the long run. In addition, city commercial banks are becoming the main source and contributor of systemic risk.

Systemic Risk in Vietnam Stock Market
Systemic risk is one of the issues currently being paid attention to in ensuring the stability and sustainability of the global financial system in general and the securities market of countries in particular. The paper studied the systemic risk of enterprises listed on Ho Chi Minh City Stock Exchange in the period from the first quarter of 2010 to the second quarter of 2017. The authors have applied the VaR and DCoVaR method to compare the loss level of businesses to the systemic risk of the whole market upon an unstable event. The study also found a disadvantage of using VaR in measuring systemic risk in that it was still "individual" and "single" and didn?t consider the spread among various entities in the market. In addition, the sensitivity of listed companies varied under normal and volatile conditions. The results showed that DCoVaR is a more suitable measure in considering the contribution level of companies to the systemic risk of the whole market. Calculated results were proposed as an indicator for investors and market managers in order to limit systemic risks in the future.

Bank Networks and Systemic Risk: Evidence from the National Banking Acts
The National Banking Acts (NBAs) of 1863 1864 established rules governing the amounts and locations of interbank deposits, thereby reshaping the bank networks. Using unique data on bank balance sheets and detailed interbank deposits in 1862 and 1867 in Pennsylvania, we study how the NBAs changed the network structure and quantify the effect on financial stability in an interbank network model. We find that the NBAs induced a concentration of interbank deposits at both the city and bank levels, creating systemically important banks. Although the concentration facilitated diversification, contagion would have become more likely when financial center banks faced large shocks. (JEL E44, G01, G21, G28, L14, N21)

Analyzing Political and Systemic Determinants of Financial Risk in Local Governments
Studies have shown that political variables can influence the volume of government debt and have recommended investigating the joint effects of diverse factors on the risk of local government default. Considering the relation between economic management and political constraints, this paper examines the joint influence of political and systemic factors on the risk of loan default by Spanish local governments. To do so, we analyze 148 city councils for the period 2006 2011, using a logit model with panel data and an artificial neural network. The empirical results indicate that the financial risk of local governments is affected both by political factors specific to each case and, simultaneously, by systemic variables for the country. Specifically, political variables such as the mayor not having economics related university studies, the under representation of female councilors in the municipal corporation, municipal government by a party with a progressive ideology, and ideological alignment between the municipal and the regional government are all associated with greater financial risk. Moreover, rising national unemployment, an increased sovereign risk premium, the impact of the electoral cycle, and that of declining economic growth are all factors that may increase the risk of default. The findings presented are of great potential interest for governments, managers, national and international fiscal authorities, financial regulators, and citizens at large, because an understanding of the significance of these variables can help authorities make appropriate decisions to prevent and/or overcome problems related to municipal insolvency.

Bank Networks and Systemic Risk: Evidence from the National Banking Acts
The reserve requirements established by the National Banking Acts (NBAs) dictated the amounts and locations of interbank deposits, thereby reshaping the structure of U.S. bank networks. Using unique data on bank balance sheets, along with detailed interbank deposits in 1862 and 1867 in Pennsylvania, we study how the NBAs changed the bank network structure. Further, we quantify the effect on financial stability in a model of interbank networks with liquidity withdrawal. We find that the NBAs led to a concentration of interbank deposits at both the city and the bank level, creating systemically important banks in major financial centers. Our quantitative results show that the newly emerged system was "robust yet fragile" while the concentration of linkages made the system more resilient in general, it increased the likelihood of contagion when financial center banks faced large shocks.

Assessment of risk factors concerning of systemic lupus erythamatosus on women and outcome of pregnancy at Karbala city
Background: Systemic lupus erythematosus (SLE) is a systemic inflammation autoimmune disease which can effect multiple systems of the human body. The underlying cause of SLE is not fully known, however, genetics, heredity, and environmental features are associated with the severity and outcome of the disease. SLE is a chronic disease that is more frequent in women of reproductive age. The relationship between lupus and pregnancy is problematic: maternal and fetal outcomes are worse than in the general population, and the management of flare ups is difficult during this period. Objectives: The aim of the present work was ANA and anti dsDNA to determine the prevalence of autoimmune in a cohort of Iraqi SLE woman patients and to describe their sites and relation to clinical characteristics, laboratory features and disease activity in pregnant women. Patients and Methods: A total of 30 patients with SLE (all patients were females) with ages ranged between (20 40) years were taken from (Al Hassein Medical city/Karbala) Control group consisted of 20 healthy females who were free from signs and symptoms of SLE, with ANA tested by Immunofluorescence technique, also anti dsDNA antibody was measured by enzyme linked immunosorbent assays kit supplied by (Euroimmune, Germany) C3 and C4 were measured using turbidimetry technique, their kits were supplied by(Vital Diagnostics Italy Results: In the present study the ANA antibodies were positive in 100% of the cases. The mean value of anti dsDNA (300.4+ 201.44) which shown in highly significance. In addition results showed that serum levels of C3 and C4 were low significantly in pregnant women of SLE in coparsion with those healthy in significant negative correlation between C3 and C4 levels in lupus. Conclusion: The effect of systemic lupus erythematosus on pregnant women are associated with high risk on pregnant itself and her baby in compeer with healthy pregnant women.
