Grassland ecology : an analysis of Wolf Totem from an ecological perspective.

Much discussion has been done on Jiang Rong’s presentation of the national character of the Chinese in Wolf Totem, so that it overshadows an equally important aspect of the novel: the grassland ecology. Thus, we aim to contrast the different attitudes towards nature of the nomadic Mongols on the one pole, and the Han Chinese, the migrant and young Mongols on the other. Besides, we try to summarize the nomads’s ecosophy as reflected in the novel. Ecotheory, especially Arne Naess’ ecosophy T offers a very efficient tool for our exploration. One problem yet to be solved, however, is the regression of the traditional ecosophy engendered by the challenges from different social forces such as politics and economy. Thus, how to preserve the traditional positive ecosophy needs efforts from all parties apart from the ecologists

Xi Sigma Pi, Gamma Chapter

Xi Sigma Pi is a national honor society for students of forestry. Once a person has been initiated into the fraternity, they are a lifelong member of the national organization. The Iowa State University chapter of Xi Sigma Pi is Alpha Gamma, and includes faculty, staff, graduate students, and undergraduates within forestry and other departments

A breakdown voltage model for implanted resurf p-LDMOS device on n+ buried layer

This paper presents an analytical expression of the breakdown voltage of a high voltage implanted RESURF p-LDMOS device which uses the n+ buried layer as an effective device substrate. In this model, the doping profile of the buried layer is considered and discussed. The implant dose for the drift region to implement the RESURF principle is also described by this model. Results calculated from this model are verified by experimental values

On Jiang's asymptotic distribution of the largest entry of a sample correlation matrix

Let $\{X, X_{k,i}; i \geq 1, k \geq 1 \}$ be a double array of nondegenerate i.i.d. random variables and let $\{p_{n}; n \geq 1 \}$ be a sequence of positive integers such that $n/p_{n}$ is bounded away from $0$ and $\infty$. This paper is devoted to the solution to an open problem posed in Li, Liu, and Rosalsky (2010) on the asymptotic distribution of the largest entry $L_{n} = \max_{1 \leq i < j \leq p_{n}} \left | \hat{\rho}^{(n)}_{i,j} \right |$ of the sample correlation matrix ${\bf \Gamma}_{n} = \left ( \hat{\rho}_{i,j}^{(n)} \right )_{1 \leq i, j \leq p_{n}}$ where $\hat{\rho}^{(n)}_{i,j}$ denotes the Pearson correlation coefficient between $(X_{1, i},..., X_{n,i})'$ and $(X_{1, j},..., X_{n,j})'$. We show under the assumption $\mathbb{E}X^{2} < \infty$ that the following three statements are equivalent: \begin{align*} & {\bf (1)} \quad \lim_{n \to \infty} n^{2} \int_{(n \log n)^{1/4}}^{\infty} \left( F^{n-1}(x) - F^{n-1}\left(\frac{\sqrt{n \log n}}{x} \right) \right) dF(x) = 0, \\ & {\bf (2)} \quad \left ( \frac{n}{\log n} \right )^{1/2} L_{n} \stackrel{\mathbb{P}}{\rightarrow} 2, \\ & {\bf (3)} \quad \lim_{n \rightarrow \infty} \mathbb{P} \left (n L_{n}^{2} - a_{n} \leq t \right ) = \exp \left \{ - \frac{1}{\sqrt{8 \pi}} e^{-t/2} \right \}, - \infty < t < \infty \end{align*} where $F(x) = \mathbb{P}(|X| \leq x), x \geq 0$ and $a_{n} = 4 \log p_{n} - \log \log p_{n}$, $n \geq 2$. To establish this result, we present six interesting new lemmas which may be beneficial to the further study of the sample correlation matrix.Comment: 16 page
