If we make a set of measurements, such as narrow-band or multicolour photo-electric measurements, which are designed to improve a scheme of classification, and in particular if they are designed to extend the number of dimensions of classification, i.e. the number of classification parameters, then some important problems of analytical procedure arise. First, it is important not to reproduce the errors of the classification scheme which we are trying to improve. Second, when trying to extend the number of dimensions of classification we have little or nothing with which to test the validity of the new parameters.Problems similar to these have occurred in other areas of scientific research (notably psychology and education) and the branch of Statistics called Multivariate Analysis has been developed to deal with them. The techniques of this subject are largely unknown to astronomers, but, if carefully applied, they should at the very least ensure that the astronomer gets the maximum amount of information out of his data and does not waste his time looking for information which is not there. More optimistically, these techniques are potentially capable of indicating the number of classification parameters necessary and giving specific formulas for computing them, as well as pinpointing those particular measurements which are most crucial for determining the classification parameters.

Contrast Information

Many factors (e.g., resolution of microscope, type of tissue, and preparation of sample) affect electron microscopical images and alter the amount of information that can be retrieved from a specimen. Of interest in this report are those factors associated with the evaluation of epoxy embedded tissues. In this context, informational retrieval is dependant, in part, on the ability to “see” sample detail (e.g., contrast) and, in part, on tue quality of sample preservation. Two aspects of this problem will be discussed: 1) epoxy resins and their effect on image contrast, information retrieval, and sample preservation; and 2) the interaction between some stains commonly used for enhancing contrast and information retrieval.

Amount Of Information

Information retrieval finds itself at an interesting juncture, where the amount of information that is available to people increases every day from its already bewildering limit. The problem is how to get the information we need in a timely and efficient fashion, without delivering useless or unwanted information. Current Web-Based IR systems do their best, but they will find it increasingly. . .

Solving Russian Velars: Palatalization, the Lexicon, and Gradient Contrast Utilization

Lexical Items

Palatalized velars in Russian are often considered exceptional because they are neither fully predictable, nor clearly unpredictable. They are an example of a common phonological relationship in which sounds have the potential to distinguish words but are only utilized in limited contexts and/or lexical items. These “intermediate phonological relationships” (Goldsmith) are problematic for traditional phonological theories which make a binary distinction between predictable sounds (allophones; dealt with in the grammar) and unpredictable sounds (phonemes; dealt with in the lexicon). To deal with intermediate phonological relationships in a principled way we must reconsider assumptions about the type and amount of information stored in the lexicon.

Proper Analysis

Prompt cooling to remove field heat is an essential part of proper postharvest handling for many types of fresh fruits and vegetables. Growers, consultants, and horticultural agents are often encouraged to collect cooling data (time vs. temperature) in order to compare cooling rates for different systems, containers, etc. These data can be misleading and confusing and seldom yield much useful information. With proper analysis, cooling data can yield a large amount of information. The problem is not the fault of the data, as much as the lack of simple methods to analyze these data. This presentation will demonstrate several simple methods to extract useful information from cooling data.

The stories in Qur'an are Allah’s decrees which convey more beau-tiful values beyond any religious text ever written. It is the holiest scripture and is written  in a wonderful, understandable, and attract-ive language humbly conveying a vast amount of information about life and events that happened in the past. It’s aim is to be an object of reflection for human beings living in this age and the future. Even more so, the stories in Al-Qur'an also entail an educative function providing learning materials,  and teaching methods, regarding the transformative power of Islam and the internalization of true religious values.

In this chapter, Yaghi offers detailed suggestions on how to code qualitative data after they have been gathered. Based on his doctoral dissertation, this chapter explains that the logic behind coding qualitative data is to turn a significant amount of information into categories that can be used to explain a phenomenon, reveal a concept, or render the data comparable across different case studies. It also elaborates through examples from author’s fieldwork in Tunisia, Egypt, and Jordan on four potential problems that may face researchers in coding qualitative data. These are the questions of preparation, categorization, consistency, and saturation. The chapter concludes by asking researchers to be flexible, and open to the process of trial and error in coding, to confront the data with questions before categorization, and to gather sufficient data on their topics before running their qualitative surveys.
