Observations of six mother-infant dyads at infant ages of approximately 13 weeks, 20 weeks, 27 weeks and 35 weeks served as a data base to examine difficulties associated with the use of conversational features (such as the avoidance of coaction) in the analysis of mother-infant vocalization episodes. The difficulties are associated with procedures involving: (i) The pooling of data, (ii) The unit of analysis, and (iii) The selection of appropriate 'expected' values for dyadic parameters used in tests of statistical inference. To illustrate these difficulties, the use of the odds ratio statistic as a means of determining such dependence is examined and alternative approaches are suggested.

The paper studies didactic approaches used to create self-test units in textbooks. The system of self-control skills formation is considered on the example of textbooks on reading. The authors define the approaches of textbooks published in Kyrgyzstan, Kazakhstan, Russia, the Netherlands, Germany, France and Greece in Cyrillic, Latin and Greek alphabets to the organization of self-control based on the content and structure. The didactic features of these publications are described from the viewpoint of realizing the possibility of self-test of the tasks and exercises. German and Greek textbooks with an original system of self-test in illustrative and textual form are singled out and analyzed in detail. The types of tasks for the thinking development in schoolchildren are distinguished with the use of cluster analysis. The content analysis helped the authors in identifying the five groups of multiple or single selection of objects and things tasks and exercises, reproduction of previously studied letters, sequencing, correlation, and design. The paper shows the similarities and differences in the implementation of self-control skills formation in various editions of textbooks. The separate unit of exercises for the development of fine motor skills are considered as a means of developing graphic accuracy and a prerequisite for the transition to the stage of logical thinking.

Author Cocitation Analysis

The previous two chapters examined the two alternative approaches of retrieving cocitation counts using custom databases and cocitation frequency counts extraction systems. The cocitaion frequency counts are the inputs to the SAS or SPSS systems for multivariate statistical analysis. The primary purpose of this chapter is to overview several important steps in author cocitation analysis. ACA consists of the six major steps beginning with the selection of author sets for further analysis, then collection of cocitation frequency counts, statistical analysis of the cocitation frequency counts, and the validation and interpretation of statistical outputs.

We review Bayesian and Bayesian decision theoretic approaches to subgroup analysis and applications to subgroup-based adaptive clinical trial designs. Subgroup analysis refers to inference about subpopulations with significantly distinct treatment effects. The discussion mainly focuses on inference for a benefiting subpopulation, that is, a characterization of a group of patients who benefit from the treatment under consideration more than the overall population. We introduce alternative approaches and demonstrate them with a small simulation study. Then, we turn to clinical trial designs. When the selection of the interesting subpopulation is carried out as the trial proceeds, the design becomes an adaptive clinical trial design, using subgroup analysis to inform the randomization and assignment of treatments to patients. We briefly review some related designs. There are a variety of approaches to Bayesian subgroup analysis. Practitioners should consider the type of subpopulations in which they are interested and choose their methods accordingly. We demonstrate how subgroup analysis can be carried out by different Bayesian methods and discuss how they identify slightly different subpopulations.

Parameter Estimation Methods

Since 1971, interest in the use of decompositional multiattribute preference models in marketing has been increasing. The applications have varied in terms of the type of data used, behavior predicted, and methods used for estimating parameters. The authors examine the effect of different data collection and estimation procedures on parameter estimates and their stability and validity. An actual data base is used. A detailed comparison is made of the alternative approaches of parameter estimation and suggestions are given for the potential users of decompositional multiattribute preference models.

Background and Aims. Biliary stenting for the treatment of biliary stricture is the most common indication of ERCP, but the procedure is sometimes unsuccessful because of severe strictures. The Swing Tip is useful for passing through severe strictures because it has a manually operable tip. The efficacy of using a Swing Tip was retrospectively evaluated. Methods. The 2353 patients who underwent ERCP for biliary stenting at our facility between January 2012 and July 2018 were enrolled. In all patients, procedures were begun using tapered tip-catheters, and Swing Tips were used if the procedure was found to be difficult with other devices. The indication for switching to the Swing Tip and the technical success rate were retrospectively evaluated. Results. A total of 99 patients (4.2%) underwent ERCP using the Swing Tip, including 49 patients for the selection of biliary branches and 50 for exchanging guidewires for rigid ones. In these patients, biliary stenting was successful in 22 patients (44.9%) and 45 patients (90%), respectively. The other 32 patients with failed endoscopic biliary drainage were treated via alternative approaches, such as percutaneous procedures, surgeries, or conservative treatments. There were no adverse events associated with the Swing Tip. Conclusion. The Swing Tip was technically feasible especially for exchanging guidewires during ERCP. Percutaneous procedures or surgical treatments can be avoided by using the Swing Tip. Ethical Statements. This study was approved by the institutional review board of Okayama University. All subjects provided informed consent. The study was registered in the UMIN protocol registration system (identification number UMIN 000033692).

This study aims to assess the similarities and differences between Finland and Spain in terms of Leadership in Energy and Environmental Design for Existing Buildings (LEED-EB) Gold large office building-type projects transitioning from version 3 (v3) to version 4 (v4). The percentages of the average scores are used here to assess the achievements of the LEED-EB data. The natural logarithm of the odds ratio lnθ and Fisher′s exact 2 × 2 tests with a mid p-value are used to evaluate dichotomous data, while the exact Wilcoxon–Mann–Whitney and Cliff′s δ effect size tests are used to evaluate ordinary data. The results for LEED-EB Gold large offices demonstrate similar certification strategies in Finland and Spain. These results may be useful to LEED-EB practitioners in Finland and Spain for facilitating the selection of appropriate certification strategies in line with identified high-performance credits for large offices.
