Review of The nature of nondirective group psychotherapy. An experimental investigation.

Reviews the book, The nature of nondirective group psychotherapy. An experimental investigation by Leon Gorlow, Erasmus L. Hoch, and Earl F. Telschow (1952). This study was designed to investigate with quantitative precision various parameters of the process of nondirective group psychotherapy. Acknowledging the tentative, exploratory nature of the investigation, the authors outline a threefold objective: (a) analysis of the uniformity of group patterns of verbal behavior as a function of variables like time, differing membership, and leadership; (b) delineation of the therapeutic value of the group, per se; and (c) evaluation of the role of the group leader. This book is successful in providing interesting hypotheses and techniques for analyzing protocols. The limitations of its experimental design, however, prevent an evaluation of either the unique characteristics or therapeutic value of nondirective group psychotherapy.

The use of response patterns to improve item scoring.

This study compared the validity of 2 methods of scoring the Minnesota Vocational Interest Inventory. One method used keys developed in the usual manner by selecting items that differentiated between specific occupational groups and a reference group of tradesmen-in-general. The other method used keys developed by selecting items that were part of response patterns that differentiated between criterion and reference groups. 3 occupational keys were developed and cross-validated: painter, printer, and electrician. Results showed that the keys were about equal in their ability to separate criterion from reference groups, but the key developed from response patterns used far fewer items.

Stereotypic behavior and development.

Evidence was presented to show that some reflexes of the neonate are organized in rhythmical patterns of high frequency; that stereotypic mannerisms are organized in similar high frequency rhythms; and that under conditions of functional and structural regression, both rhythmical reflexes and stereotypic mannerisms may reappear in their archaic forms and frequencies. With respect to neonatal motor rhythms, it was proposed that development implies a phase interaction of two or more fixed frequencies giving rise to qualitatively different temporal patterns. This proposition was opposed to the suggestion that neonatal motor rhythms are suppressed by central nervous system maturation and replaced by learned sequences which in turn are reinforced by environmental contingencies.

The Leaf Turns.

This commentary uses the leaf as a system of patterned uniqueness as a metaphor for the paradox of the scientific study of personality. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

An algorithm to detect linearly separable clusters of binary patterns

The clusters of binary patterns can be considered as Boolean functions of the (binary) features. Such a relationship between the linearly separable (LS) Boolean functions and LS clusters of binary patterns is examined. An algorithm is presented to answer the questions of the type: “Is the cluster formed by the subsets of the (binary) data set having certain features AND/NOT having certain other features, LS from the remaining set?” The algorithm uses the sequences of Numbered Binary Form (NBF) notation and some elementary (NPN) transformations of the binary data.     

A Controlled Experiment Comparing the Maintainability of Programs Designed with and without Design Patterns—A Replication in a Real Programming Environment

Software design patterns seek to package proven solutions to design problems in a form that makes it possible to find, adapt and reuse them. To support the industrial use of design patterns, this research investigates when, and how, using patterns is beneficial, and whether some patterns are more difficult to use than others. This paper describes a replication of an earlier controlled experiment on design patterns in maintenance, with major extensions. Experimental realism was increased by using a real programming environment instead of pen and paper, and paid professionals from multiple major consultancy companies as subjects. Measurements of elapsed time and correctness were analyzed using regression models and an estimation method that took into account the correlations present in the raw data. Together with on-line logging of the subjects work, this made possible a better qualitative understanding of the results. The results indicate quite strongly that some patterns are much easier to understand and use than others. In particular, the Visitor pattern caused much confusion. Conversely, the patterns Observer and, to a certain extent, Decorator were grasped and used intuitively, even by subjects with little or no knowledge of patterns. The implication is that design patterns are not universally good or bad, but must be used in a way that matches the problem and the people. When approaching a program with documented design patterns, even basic training can improve both the speed and quality of maintenance activities.     

LBGK Simulations of Turing Patterns in CIMA Model

A lattice Bhatnagar–Gross–Krook (LBGK) model for reaction-diffusion systems is presented. This model provides a mesoscopic approach to the dynamics of spatially-distributed reacting systems. Pure diffusion phenomena are computed and the results are agreement with the theoretical predictions. This method is also applied to formation of Turing patterns in chloride-iodide-malonic acid (CIMA) reactive model. We get hexagonal structures and stripes which are agreement with other numerical results and experimental results.

使用语义限定的加权浏览模式的挖掘

指出了一种加权的Web挖掘技术，从Web日志中发现语义限定的加权序列模式，每个网页由不同的专家给出语义上的需要性评估，这些语义评估再被转化成表示权重的模糊集。最后由用户指定语义上的最小支持度和最小偏爱度进行挖掘，这种语义上的输入和输出更自然，更易被理解。最后通过一个例子描述了所提出的方法。
