济阳拗陷深层隐蔽构造及其勘探意义

基于构造本身的复杂性, 提出了隐蔽构造的概念, 认为隐蔽构造是指那些受勘探技术限制以及构造自身的复杂性而不能明确其特征、 性质和演化历史的构造。对于隐蔽构造的研究应以界面和变形标志的识别为基础, 地层结构的分析为核心, 以先进的构造思维和技术手段为保证。济阳拗陷深层发育有大型走滑断裂带、 反转构造、 构造转换带或过渡带、 底辟构造带、 潜山内幕构造、 复杂的断裂带、 隐伏断裂等隐蔽构造样式。对于潜山构造的勘探, 可以顺走滑断裂带进行勘探。隐蔽构造样式的识别对拓展深层油气勘探新领域,优选与评价有利油气富集区带, 以及进一步的油气地质综合研究等, 均具有一定意义。     

论拜占廷帝国科穆宁制度的历史作用

科穆宁制度是1081年阿莱克修斯上台后建立的以皇帝为中心、以皇帝的家族为统治基础的政治制度。这一制度确立了皇帝家族和军事贵族的统治地位,建立起庞大的皇帝家族对非皇帝家族的绝对优势,为科穆宁王朝前三位皇帝提供了坚实的统治支柱,使他们加强了中央集权,恢复并保持了对贵族、官僚政治、军队和君士坦丁堡民众的控制,最终遏制了11世纪以来十分严重的贵族叛乱和阴谋活动,为拜占廷帝国在1081—1180年出现的百年繁荣局面奠定了基础。

“我”的变奏

作为一种以主观抒情为基本手段的文体 ,诗歌 (尤其是抒情诗 )中的“我”便具有了举足轻重的中心地位。通过对“我”在 2 0世纪中国诗歌中变化历程的考察可以看出 ,政治文化干预和影响了本世纪中国文学的发展 ;另一方面 ,“我”在诗歌中的变迁 ,也反映了 2 0世纪中国诗歌自我完善的艰难历程。     

英语话语标记语之构式语法分析——以“Imean”为例

话语标记语“Imean”有多种语用功能意义。在构式语法的框架下,试图把“Imean”作为一个构式来研究,分析其形式、意义、功能,然后在此基础上提出“Imean”的形成是一个语法化的结果这样一个假设,是从第一人称的动补构式[verb＋complement]语法化为话语标记语构式[discoursemarker]。构式语法可以成功解释语法化的诱因。这样的分析可促进运用构式语法对话语标记语的研究,同时也显示出构式语法的强大解释力。     

ESTIMATING A RATIO OF MEANS FROM BIVARIATE COUNTS WITH APPLICATIONS IN STEREOLOGY

In survey sampling and in stereology, it is often desirable to estimate the ratio of means θ= E(Y)/E(X) from bivariate count data (X, Y) with unknown joint distribution. We review methods that are available for this problem, with particular reference to stereological applications. We also develop new methods based on explicit statistical models for the data, and associated model diagnostics. The methods are tested on a stereological dataset. For point‐count data, binomial regression and bivariate binomial models are generally adequate. Intercept‐count data are often overdispersed relative to Poisson regression models, but adequately fitted by negative binomial regression.     

Balanced and partially balanced incomplete block designs with autocorrelation errors

The paper aims to find variance balanced and variance partially balanced incomplete block designs when observations within blocks are autocorrelated and we call them BIBAC and PBIBAC designs. Orthogonal arrays of type I and type II when used as BIBAC designs have smaller average variance of elementary contrasts of treatment effects compared to the corresponding Balanced Incomplete Block (BIB) designs with homoscedastic, uncorrelated errors. The relative efficiency of BIB designs compared to BIBAC designs depends on the block size k and the autocorrelation ρ and is independent of the number of treatments. Further this relative efficiency increases with increasing k. Partially balanced incomplete block designs with autocorrelated errors are introduced using partially balanced incomplete block designs and orthogonal arrays of type I and type II.     

Higher order moments of order statistics from INID symmetric random variables

In this paper we present analogues of Balakrishnan's (1989) relations that relate the triple and quadruple moments of order statistics from independent and nonidentically distributed (I.NI.D.) random variables from a symmetric distribution to those of the folded distribution. We then apply these results, along with the corresponding recurrence relations for the exponential distribution derived recently by Childs (2003), to study the robustness of the Winsorized variance.     

Identifying the most successful dose (MSD) in dose-finding studies in cancer

For a dose finding study in cancer, the most successful dose (MSD), among a group of available doses, is that dose at which the overall success rate is the highest. This rate is the product of the rate of seeing non-toxicities together with the rate of tumor response. A successful dose finding trial in this context is one where we manage to identify the MSD in an efficient manner. In practice we may also need to consider algorithms for identifying the MSD which can incorporate certain restrictions, the most common restriction maintaining the estimated toxicity rate alone below some maximum rate. In this case the MSD may correspond to a different level than that for the unconstrained MSD and, in providing a final recommendation, it is important to underline that it is subject to the given constraint. We work with the approach described in O'Quigley et al. [Biometrics 2001; 57(4):1018-1029]. The focus of that work was dose finding in HIV where both information on toxicity and efficacy were almost immediately available. Recent cancer studies are beginning to fall under this same heading where, as before, toxicity can be quickly evaluated and, in addition, we can rely on biological markers or other measures of tumor response. Mindful of the particular context of cancer, our purpose here is to consider the methodology developed by O'Quigley et al. and its practical implementation. We also carry out a study on the doubly under-parameterized model, developed by O'Quigley et al. but not
