In this paper representative differential equation models for diffusion process are compared. These models are(1)simple logistic curve, (2)harmonic logistic curve, (3)exponential logistic curve, (4)modified exponential curve, (5)Gompertz curve, (6)Bass's model. Logistic-type models((1), (2), (3))are based on the assumption of the effects of the interactions among members in a group.On the other hand, modified exponential curve model is based on the assumption of the effects of the outside information source. Bass's model synthesizes these two components of diffusion process. The six models are applied to data on consumer durables, music records, and information diffusions. The results show that Bass's model yields the better predictions for most of actual data than any other model.

This study explores the distributional characteristics of nouns of Japanese prime ministers' Diet addresses for interpreting two political phenomena. Previous content analysis studies focused only on a few content words for interpreting social phenomena and stylistic studies used stylistic characteristics independent on content of the texts with the aim of detecting their authors, genres, and chronological variations. This study focused, instead of these features, on distributional characteristics of nouns for better understanding two political phenomena: (a) the difference between the two types of Diet addresses delivered by Japanese prime ministers, and, (b) the perceived changes made to these addresses by two powerful prime ministers. This study expands the aims and scopes of text analysis by showing the effectiveness of exploring these microscopic textual characteristics for interpreting political phenomena.

Quality of life (QOL) is a subjective assessment and is included among patient-re-ported outcome (PRO) studies. QOL is as important for cancer patients as objectiveassessments such as survival and response rates. However, PRO studies are more diffi-cult to conduct than are studies to assess objective data. Regarding QOL studies whichare important among PRO studies, first we describe QOL, which Dr. Hayashi promotedaiming to improve. Then we describe the methods of assessing QOL. Finally, we in-troduce a novel self-monitoring QOL intervention. In the methods of assessing QOL,Minimal clinically important difference (MCID) and response shift are major challengesamong the methods of assessing QOL. MCID enables recognition of the patient’s per-ceptions, as well as the clinical outcomes. It is important to consider response shift wheninterpreting actual change of QOL. In the introduction of novel self-monitoring QOLintervention, QOL assessments are often seen as being for research purposes, thoughQOL self-monitoring should also be implemented in daily clinical routines. QOL as-sessment is often used as an outcome measure in clinical trials, and cancer diagnosisand treatments affect patients’ QOL. However, medical personnel may not sufficientlyunderstand patients’ problems, including QOL. In advancing the study of QOL, it is afuture task to address how QOL assessment information is to be fed back to patients.

Since the telephone (RDD) poll of the day is carried out in the call center, which is highly managed, the risk of operator's error generation is low. However, this report suggests the risk of operator's error generation due to intervene of operator's judgment. It is the case that the questionnaire is not carefully examined. Now therefore, the question with an unclear meaning with a long sentence and/or an open-answer question must be avoided when there is not enough time for developing a thorough questionnaire.

An analysis method is considered that concerns count data with zero truncation, i.e. frequencies of occurrence of an event greater than or equal to 1 are only reported and the frequency of zero occurrence is not available. Relationship between the counts of occurrences of two related events is particularly interested. Such relationship is modeled by a bivariate gamma-Poisson distribution in this paper. To estimate the unknown parameters involved in the model, a simple method based on sample means is proposed. The estimation procedure is applied to some real datasets and interpretations of the results obtained are given. An additional point emphasized in this paper is that the frequency of zero count is not always trusted even the number is reported.

This study addresses three issues on proactive behavior (PB) in occupational/organizational context, by using four samples gathered from Japan and China. The first issue is to develop the dimensional structure model of PB. A four-factor model was found out by exploratory factor analysis using Japanese student samples (n=384), and validated by multi-group confirmatory factor analysis using Japanese (n=1009) and Chinese (n=308) employee samples. The second issue is to develop a 12 item-Scale (PBS) based on item response theory. PBS was supported by two construct-related validity evidences across the two countries' employee samples: 1) the configural- & metric-invariance of the four-factor model measured by PBS; and 2) the reproducibility of both positive & negative correlation pattern among PBS score and some work-related variables. Finally, the third issue is to clarify the similarities/differences between Japanese and Chinese employees. The result revealed two similarities, which were referred in the second issue, and the following three differences: 1) the average hurdle for taking PB in the two countries' organizations; 2) the average level of PB; 3) what aspect (process or outcome) of work has strong relevance to PB. One explanation for the three differences is the distinction in occupational/organizational mobility due to performance-based system between Japan and China.

The purpose of this study was to examine how the interpretability of a purchased product changes by mindset manipulations based on the Mental Simulation (MS) or Construal Level Theory (CLT). While the manipulation of MS associates the targeted products, that of the CLT does not. We investigated whether this difference affects the accuracy of the survey. In this experiment, participants were randomly assigned to four groups (photo-simulation manipulation (MS) vs. how-manipulation (MS) vs. low-level manipulation (CLT) vs. non-manipulation); they completed each task and conjoint measurement. The result of the experiment showed that photo-simulation manipulation and how-manipulation better contributed to the estimation of the real purchased product than non-manipulation did. However, this was not the case for low-level manipulation.

The varimax rotation, a special case of the orthomax method, usually contains the process of normalization by the communalities of manifest variables. After rotation, factor loadings are re-scaled so that the communalities have original values. Although the standard errors of rotated factor-loadings have been discussed from the general view point of estimation of parameters with restrictions, the actual standard errors for normalized rotation have not been provided. In this paper a method of estimating the asymptotic standard errors in the normalized orthomax rotation is given. Two artificial examples are provided in which standard errors become extremely large with or without normalization.

Text classification results often vary depending on the detailed factors in data analysis, including feature data, classification method, and parameter sets adopted in the analysis. The author of an anonymous text can be generally identified by extracting a set of distinctive features of the text, and then using the features to find the most likely author. Numerous efforts have been made to develop the feature extraction technique with more robustness and the classification algorithm, but an important issue is how to select the features datasets and classification method. To address this issue, we propose an integrated classification algorithm that extracts multiple feature datasets from differing viewpoints and aspects of a text and applies multiple strong classifiers to the datasets. Our proposed method achieved 100% accuracy in identifying the authors of literary works and student essays, and identified the author of all but 1 out of 60 diaries which were written by 6 different people.Our proposed method achieved equivalent or better accuracy than the case when any a strong classifier applied to individual feature dataset. Furthermore, the accuracy in identifying the authors of student essays increased by roughly two percentage points.

Advertising investment risk has become high due to the explosive information increase and the commoditization evolution. In order to reduce such risk, it is important to understand the relation between advertising elements and consumer responses, and apply the knowledge to decision making process of advertising production. There have been lots of efforts to develop a set of scales to measure the advertising perceptions and relate it to the consumer responses. However, that is not adequate when we assume to support the actual practices of the advertising production. Although the advertising perceptions are helpful to understand the reasons of the consumer responses, they don't directly lead the way to the advertising production.In this study, we analyze the effects of 28 elements of TV advertisements on the advertising perceptions and the consumer responses. The elements adopted in this study are controllable by advertisers so that they can apply the research findings to the advertising production. Empirical analyses using a dataset of the advertising perceptions and the consumer responses to more than 800 TV advertisements clarified not only the important advertising elements which had high impacts on the consumer responses but also how and why they affect consumer responses. Simultaneously, simulation of the consumer responses using random forests was found to be helpful to explore the effective combination of the advertising elements.

Procedures that include flexibility cause fluctuation and other individual differences in experimenter behavior. This study aims to quantify such fluctuation and individual differences in procedures by modelling human behavior. In water measurement, for example, considerable longitudinal data must be compiled, especially monitoring the progress in water height. By analyzing the principal component, the “planning” and “adjustment” components are obtained. The human behavior model was then created to link principal component score to experimenter characteristics. In this model it was assumed that the principal component score was decided by procedural elements such as water velocity, and by contextual elements such as experimenter trial number, final results of previous experiments, and accumulated minutes. Model coefficients are calculated as parameters of each experimenter by fitting the model. Parameter sign revealed that experimenters tend to respond to water velocity change by “adjustment”, and “planning” is used as repeated time increase and failures in previous time. Prediction values were in good agreement with actual values, proving that mathematical modelling of human behavior has the potential for effectively predicting individual behavior.

In this rejoinder, special attentions are paid to error covariances and specific factors in the comparison between SEM and traditional methods. When a factor analysis model receives a poor fit, it does not make sense to simply remove important variables although inconsistent with the factor analysis model, as pointed out by the discussants. It is to be emphasized that a better way than removing the variables is to allow for error covariances, in order to overcome the inconsistency problem. The model with error covariances guarantees the invariance of estimation results over item selection. The discussants pointed out that an important difference between a scale score (sum of items) and a measurement model by effect indicators in SEM is that a scale score includes specific factors whereas a measurement model excludes them. Practitioners could use scale scores when they are interested in effects of specific factors as well as a common factor. It is argued, however, that appropriate use of error terms and a common factor in SEM can make better inference than the use of unidimensional scale scores, because the error terms of effect indicators contain information on specific factors and they can individually evaluate the effects of the common factor and the specific factors in SEM. Other related topics are also discussed.

Network analysis is a method which explains an actor’s action and result from the network which surrounds the actor. Although network analysis is getting a result with many fields, practical use on marketing research is behind. The factor is because it is ambiguous how various network indices should be interpreted and utilized in marketing research. In this paper, summarizing network analysis indices, models, and previous works, the application possibility in marketing research is viewed by showing some examples of analysis in consideration of the above-mentioned factor.
