Constructions of Almost Optimal Resilient Boolean Functions on Large Even Number of Variables

In this paper, a technique on constructing nonlinear resilient Boolean functions is described. By using several sets of disjoint spectra functions on a small number of variables, an almost optimal resilient function on a large even number of variables can be constructed. It is shown that given any $m$, one can construct infinitely many $n$-variable ($n$ even), $m$-resilient functions with nonlinearity $>2^{n-1}-2^{n/2}$. A large class of highly nonlinear resilient functions which were not known are obtained. Then one method to optimize the degree of the constructed functions is proposed. Last, an improved version of the main construction is given.Comment: 14 pages, 2 table

A Study on the Location Determinants of the US FDI in China

he US foreign direct investment in China plays a leading role in the process of introducing FDI to China. This paper carries on an empirical research dynamically on the location factors of US foreign direct investment in China, adopting Johansen cointegration test, the VEC model, Granger causality test and variance decomposition technology, based on analytical data in the period from 1983 to 2006. The studying result demonstrates that there is a stable relationship among the US foreign direct investment in China, China’s GDP, fixed asset investment in China and the prophase stock of the US foreign direct investment in the long-run. And China’s GDP is the major power to induce the US FDI to bias the long-term equilibrium

Construction of Highly Nonlinear Resilient Boolean Functions Satisfying Strict Avalanche Criterion

A method is proposed to construct resilient Boolean functions on $n$ variables ($n$ even) satisfying strict avalanche criterion (SAC) with nonlinearity $>2^{n-1}-2^{n/2}$. A large class of cryptographic Boolean functions which were not known earlier are obtained

The Transmission of U.S. Monetary Policy Shocks to the China’s Output and Inflation: An Empirical Analysis

We employ the SVAR model to examine the impact of U.S. monetary policy shock on the Chinese real output and inflation. Our main result shows that the effect of transmission of short-term international capital flows is stronger than the balance of trade and the world commodity prices index. The exchange rate of RMB has the weakest transmission effect. Expansionary monetary policy shocks of the United States will increase real output and consumer price index of China and the United States; but the U.S. real output growth is higher than that of China; China’s consumer price index rise higher than that of United States. Based on this, China should gradually adjust economic growth model, increased the per capita disposable income and strengthen regulate the speculative short-term international capital flows.Key words: Monetary policy shock; Transmission channel; SVAR model; Impulse respons

Gender Gaps in the Measurement of Public Opinion About Homosexuality in Cross-national Surveys: A Question-Wording Experiment

Measures of attitudes towards homosexuality in cross-national studies have received criticism for not being ‘gender-sensitive’. The current study used a split-ballot design allowing for separate analyses of the attitudes towards ‘gay men and lesbian women’, ‘gay men’, and ‘lesbian women’ in a pooled sample of 3,381 participants from Great Britain, Hungary, and Portugal. Analyses controlling for sociodemographics showed that differences in attitudes towards male and female targets were generally small and did not interact with the gender of the rater. In addition, results showed that men’s attitudes towards homosexuality were more strongly related to their gender ideology than women’s attitudes. Implications of these findings for cross-national studies measuring attitudes towards homosexuality are discussed
