篇章类英语试题的考点效度验证

在我国大规模英语考试试卷中基于篇章类的试题占相对比较高的比例,其考点效度关乎整份试卷的效度。本文通过对篇章类英语试题考点所属构念效度的例析,说明从考点层面所获取的相关效验证据对基于篇章类试题的考点效度进行了有效验证。     

股权结构、财务杠杆对ST公司投资行为的影响——来自ST上市公司的经验数据

ST公司的投资行为是资本市场所关注的重要问题。基于此,从股东和债权人的视角,分别检验了公司股权结构和财务杠杆对ST公司投资支出的影响。以2005-2012年被ST的A股上市公司为背景,研究发现：股权集中度和长期负债均促进了企业投资,而股权制衡和短期负债抑制了企业投资。此外,规模越大的ST公司投资越少,自由现金流则与投资支出正相关。     

论高校基层党建工作的“三个基本点”

高校基层组织工作科学化水平的高低,直接影响高校党建工作的开展和高校的科学发展.从科学发展和科学执政这两条主线来看,提升高校基层党建工作科学化水平必须坚持三个基本点,即:定位自身职责是高校基层党建工作的逻辑起点,队伍建设是高校基层党建工作的支撑点,党建工作方式方法的创新是高校基层党建工作的突破点.特别是在高校基层党建工作中要有新思维、新境界、新方法.     

An in-depth mixed-methods approach to Ryan White HIV/AIDS care program comprehensive needs assessment from the Northeast Georgia Public Health District: The significance of patient privacy,psychological health,and social stigma to care

We apply a social-ecological interpretive framework to understanding relationships among patient privacy, psychological health, social stigma, and continuity in care in the HIV treatment cascade in the rural southeastern US. This research was conducted as part of the 2013 comprehensive needs assessment for the Northeast Georgia Ryan White Consortium using an anthropologically informed mixed-methods design, and a deductive-inductive approach to thematic analysis of qualitative data obtained in interviews and focus groups with service providers and service utilizers. Our comprehensive needs assessment yielded two key components. First, we identified salient phenomena influencing introduction to, retention among, and satisfaction of patients in the Ryan White-coordinated treatment cascade in NE-GA. Second, we formulated actionable recommendations around leverage points identified in the current district-wide system of care. Results highlight spatial, institutional, and interpersonal aspects of the system of care that intersect around issues of patient privacy, psychological health, and social stigma. These intersections constitute pathways by which persons living with HIV are exposed to stigma and other negative social signals regarding their health status without sufficient access to behavioral health services. These negative issues, in turn, can erect significant barriers to long-term continuity in care.

On the exact distribution of the likelihood ratio criterion for testing

The exact null distribution of the likelihood ratio criter- 2 ion for testing the hypothesis H: y = y~; z = a I, a unknown and UQ a given known vector against the alternative A =f H in a p-vari- ate normal population N (y,z) has been derived in the form of Meijer's G-function using mellin integral transform and also in a chisquare series form. Asymptotic behavior of the distribution of -2 log L has also been discussed. Percentage points for p=2(l)10for various level of significance and various degrees of freedom have been computed, but only selected tables have been presented in this paper.     

Nonnull distribution of Wilks' statistic for Manova in the complex case

In this paper, the exact distribution of Wilks' likelihood ratio criterion, A, for MANOVA, in the complex case when the alternate hypothesis is of unit rank (i.e. the linear case) has been derived and the explicit expressions for the same for p = 2 and 3 (where p is the number of variates) and general f₁ (the error degrees of freedom) and f₂ (the hypothesis degrees of freedom), are given. For an unrestricted number of variables, a general form of the density and the distribution of A in this case, is also given. It has been shown that the total integral of the series obtained by taking a few terms only, rapidly approaches the theoretical value one as more terms are taken into account, and some percentage points have also been computed.     

The distance between random points in rectangles

Since 1943, numerous papers have discussed the problem of the distribution of the distance between random points in rectangles, considering special cases such as two points in the same square, points in adjacent squares, two rectangles sharing a side and others. The problems arise in a variety of settings: operations research, population studies, urban planning, physical chemistry, chemical physics and materials science. Reported results are all of special cases with formulas specific to each case. It is possible to put such problems in a general setting with a single formula that handles all the particular cases. The method is well suited to computing and use of graphics. Now that computers and graphic output are commonplace it seems worthwhile to describe the general method and provide program outlines for computing and plotting the resulting distributions. We do that in this article.
