Needed research in the introduction and use of audiovisual materials: A special report

Conclusion Though many appropriate questions on which research needs to be done have been raised in this report, there is still one significant point which must be kept in mind: The conduct of the research itself must conform to acceptable procedures for educational research. A major concern in this whole field, but especially in the specific area of media research, has been that of such matters as the appropriateness and efficiency of the research techniques, instrumentation, and statistical procedures. Of the various activities that have been under way to upgrade research one of the more promising is a book prepared by A. A. Lumsdaine and others. Entitled Experimental Research on Educational Media: A Guidebook, it will be published soon by the U. S. Office of Education. Publications of this type should help greatly to promote the development of good researchable questions, improved procedures for studying a problem, and the postulating of tenable and generalizable conclusions. Wesley C. Meierhenry was chairman of the group of researchers who assembled at NEA headquarters in Washington to take stock of research in the educational uses of the newer media and to identify areas requiring further or initial investigations. The recommendations they drafted are presented here as edited by Dr. Meierhenry and with his linking comments.     

G单位区间上的逻辑度量结构

给出了G单位区间[0,1]的定义并在其上引入了元素间的可分度的概念,讨论了其基本性质,并在此定义的基础上确定了一个度量ρ,从而（[0,1],ρ）成为一个度量空间（文中称“G单位逻辑度量空间”）,并对G单位逻辑度量空间的性质及其结构进行了详尽的讨论,并得到一些好的结果.最后,在MV单位区间上引入了类似ρ的一个度量ρ,′并证明了（[0,1],ρ′）是通常度量空间。

The dimensions of maltreatment: introduction

This special issue includes an introduction and seven papers exploring dimensions of maltreatment including type, severity, chronicity, and substantiation status of referrals to CPS, utilizing a subsample of the LONGSCAN studies. Each paper examines one of the dimensions of maltreatment from various perspectives to determine if different conceptualizations of a dimension, examined in isolation, account for different amounts of variation in child outcomes. A final paper assesses the relationship of the combined maltreatment dimensions, including interactions, on a single sample of maltreated children from the LONGSCAN study. This final paper explores the individual contribution of the "best" conceptualizations of the maltreatment dimensions in relation to each other, and to the 10 child outcomes of interest. Implications of the findings from these papers for future research on dimensions of child maltreatment are discussed in two independent commentaries.
