This study focused on satisficing in online surveys—behavior in which panels do not devote an appropriate amount of attentional resources when answering questions. It carried out questionnaire surveys that could not be answered properly without closely reading the instructions and questions to empirically investigate the prevalence and patterns of satisficing. To detect satisficing tendencies, a screening survey was conducted with questions that necessitated a close reading of the instructions, while the main survey used questions that required a close reading of the item content. Identical surveys were carried out at two different survey companies, and results showed that satisficing due to skipping instructions occurs very frequently. Furthermore, while satisficing due to skipping scale items appears to be relatively rare, trends in satisficing differed between the survey companies. These results indicate one method for preventing satisficing, which was discussed in relation to the merits and demerits of screening respondents with satisficing tendencies.

Volcanic history of Kuchinoerabujima Volcano in the last 30,000 years is reconstructed based on tephra stratigraphy. Kuchinoerabujima is a volcanic island which is a cluster of at least nine volcanic edifices; Gokyo, Jyogahana, Ban-yagamine, Takadomori, Noike, Kashimine, Hachikubo, Furutake and Shintake. Eruptions within the last 30,000 years occurred from Noike, Hachikubo, Furutake and Shintake volcanoes. Two major pumice and scoria eruptions occurred between 15 and 11 ka after an inactive period since ca. 30ka. NoikeYumugi tephra (15-14ka, DRE>0.06km^3), erupted from the summit of Noike Volcano, consists of Yumugi pumice fall deposit and Nemachi pyroclastic flow deposit. Furutake-Megasaki tephra (12-11 ka, DRE ca. 0.8km^3) erupted from Furutake Volcano and consists of Furutake agglutinate, Furutake scoria flow deposit and Megasaki scoria fall deposits. Volcanic edifice of Older Furutake was built during the 12-11 ka eruption. Eruption style changed around 10ka, after the collapse of Older Furutake Volcano. Activities of Yougner Furutake and Shintake Volcanoes are characterized with effusion of lava flow and no major pumice eruption is recognized. Lithic tephra erupted from Younger Furutake and Shitake Volcanoes within the last 10,000 indicates repetitive Vulcanian-type and phreatomagmatic eruptions. All historical eruptions since 1841 occurred at and around Shintake crater and were Vulcanian-type explosions with emission of magmatic materials and phreatic explosions.

In this paper, we introduced a method of causal inference for arbitrary treatment regimes. We first expounded the generalized propensity score (Imai & Van Dyk, 2004) that extended the propensity score for binary treatments, and then causal inference with this generalized propensity score. Furthermore, we reanalyzed the data of relations between mass media and politics from a previous study, and discussed the usefulness of causal inference using generalized propensity scores.

In this article, monitor attitudes during online surveys were empirically examined, focusing in particular on satisficing (when survey participants do not fully engage their efforts). At first, the extent to which the satisficing tendency was dependent on personal traits was examined. We observed participants’ behavior in an online survey setting that required them to view video stimulus material consisting of news footage, and measured the length of time each participant spent viewing the footage. The results revealed that respondents who had satisficed (half-heartedly read) the scale items in a prior study (Miura & Kobayashi, 2015) were much more likely to satisfice the video footage. Then, agenda-setting and media-priming effects were used to examine the impact of satisficing during online surveys (including experimental manipulation) on empirical findings. Both examinations indicated the strong possibility that data pertaining to participants who satisficed could serve to distort empirical findings.

The effect of mobile phone e-mailing on young people's social tolerance was investigated by analyzing survey data of high school students in Japan. The results show that mobile phone e-mailing had a positive promoting effect on the homogeneity and a negative effect on the heterogeneity of personal networks. This in turn had a negative effect on social tolerance toward others. Mobile phone e-mailing enables students to select homogeneous others as companions of communication and thus brings a bias of homogeneity into their personal networks. This homogeneity bias in turn had a negative effect on the development of social tolerance in the socialization process by reducing the chance of interaction with heterogeneous others.

This study investigated the influence of satisficing on response behavior in online surveys. We compared online response data to psychological scales and logical thinking tasks conducted by an online survey company and a crowd sourcing service. In previous studies, satisficing was found to be more likely to occur among online survey monitors than among crowd sourcing service contributors. Results of the present study replicated it and showed that satisficing in terms of inattentively reading items significantly damages the integrity of psychological scales. On the other hand, it was also found that the influence of satisficing in terms of inattentively reading instructions carefully can be reduced by raising respondents' awareness. Those conducting online surveys should discuss taking active measures to minimize satisficing.

The effect of PC e-mail usage on social tolerance was investigated by analyzing representative survey data collected from electorates in Yamanashi Prefecture, Japan. The results showed that PC e-mail usage had a positive effect on social tolerance because it allows for mediating communications with heterogeneous others. These results are a clear-cut contrast to previous research, which showed that mobile-phone e-mail usage had a negative effect on social tolerance because of the increasing homogeneity of personal networks. The results indicated that while the technological limitations of mobile phone e-mail usage selectively strengthen communications with homogeneous others through the exchange of short messages, PC e-mail usage facilitates communications between heterogeneous people, because it is suitable for the exchange of the longer messages necessary for sharing the assumptions made during correspondence. From the viewpoint of nourishing "bridging" social capital, it is suggested that the promotion of PC e-mail should be encouraged by establishing appropriate policies and that the functional development of the use of the Internet on mobile phones should be empirically investigated.

Local governments have high expectations for dialogue systems that provide residents and visitors with dialogue on multiple tasks, such as tourist information, town office information, and daily life information. In addition, there is also an expectation for such dialogue systems to be given the personalities of characters possessed by local governments and to provide chat dialogues for residents. However, to give the personality of a character to the dialogue system, task dialogue data and dialogue manager that reflect the personality are essential. Based on the study of role play-based question-answering dialogue systems that reproduce characters, we propose a method for collecting dialogue data that enables task dialogue and a method of dialogue manager and response selection that facilitates task dialogue. We constructed a dialogue system that imitated a certain local government character using the proposed method and evaluated its effectiveness through a laboratory experiment and demonstration experiment. The results showed that our dialogue system had statistically better performance in both task-oriented dialogue and chat oriented one.

This paper presents results of geologic investigation of the eruptive activity in the last 300 years of Shinmoedake, an active volcano in the Kirishima Volcano Group. The recent activity of this volcano is divided into four eruptive episodes : the 1716-1717, 1771-1772, 1822 and 1959 episodes. The most important activity occurred in 1716-1717. During the 1716-1717 eruption, fallout deposits, pyroclastic flows and mudflows were widely dispersed around the volcano. The products of this episode show that the eruption progressed with time from phreatic to magmatic. These field data are in good agreement with historic records of eruptive activity. According to the historic records, the eruptive activity lasted from 11 March, 1716 to 19 September, 1717. The 1771-1772 and 1822 activities produced base surges, pyroclastic flows, fallout tephra and mudflows that were confined to the slope and eastern base of the volcano, but historic records do not reveal the details of these eruptions. The field evidence shows the same phreatic to magmatic sequence as the 1716-1717 activity. However, the eruptions of both episodes were on a smaller scale than the 1716-1717 eruption. The 1959 activity was well described. This episode produced minor gray silty to sandy lithic fallout tephra indicating that only phreatic activity occurred. The fallout was distributed northeast of the vent. In conclusion, the field evidence and historical records show that each eruptive episode of the current activity of Shinmoedake progressed from phreatic to magmatic. The eruptions are frequently accompanied by pyroclastic flows and mudflows.

The development of social capital in an online community was investigated by creating survey data of online game players. The results showed that the frequency of collective communication, the homogeneity of members, and the openness of the online community had positive effects on trust, while the size of community and community hierarchy had negative effects. This shows that participation in online communities can create social capital. Furthermore, the results showed that online social capital influences real-life behavior. For example, reciprocity online facilitated offline social participation, even after controlling for offline social capital and other real-life determinants. These results demonstrate the positive contribution of collective online communication to a democratic social system.

Ohatayama and Ohataike are adjacent volcanoes aligned in NE-SW direction at the northeastern portion of Kirishima Volcano Group, Kyushu, Japan. Ohatayama volcano has three small craters around the summit area, and Ohataike has a summit crater lake with a diameter of 400 m. Both volcanoes are composed mainly of tephra fall deposits by plinian or sub-plinian eruptions, with intercalations of pyroclastic flow deposits. The main volcanic edifice of the highest point of Ohatayama volcano was formed at least 22 cal ka BP. Tsukiyama were formed earlier than the highest point, and there is a possibility that they can be separated from the highest point. The triangulation point of Ohatayama volcano started its activities on the highest point somewhere around 17-11 cal ka BP, and forming craters A and B. Ohataike volcano was formed by erupting again around 17-11 cal ka BP, after the main volcanic edifice was formed during around 22-17 cal ka BP on the northeast side of the triangulation point. This was followed by four different modes of eruption at Ohatayama C crater in the following order: a phreatic eruption (Oy-4) in 7.6 cal ka BP, Ohatayama lava emission, magmatic and phreatic eruptions (Oy-3) in 7.1 cal ka BP, magmatic and phreatic eruptions (Oy-2) in 6.8 cal ka BP, and lastly, phreatic eruption (Oy-1) in 6.5 cal ka BP. Although no volcanic activity occurred from Ohataike volcano since 11 cal ka BP, foamy volcanic gas is currently being detected on the surface of the crater lake.

This study focuses on “satisficing” (answering behaviors in which participants do not devote appropriate attentional resources to the survey (Krosnick, 1991)) in an online survey and aims to investigate, via various indices, to what extent these behaviors are observed among students whose participation was solicited by the researchers in their universities. This study also aims to explore effective techniques to detect individuals who show satisficing tendencies as efficiently and accurately as possible. Online surveys were carried out at nine universities. Generally speaking, the predictive capability of various types of detection indices was not high. Though direct comparison with online survey panels was impossible because of differences in measurement methodology, the satisficing tendencies of university students were generally low. Our findings show that when using university students as samples for a study, researchers need not be “too intent” on detecting satisficing tendencies, and that it was more important to control the answering environment, depending on the content of the survey.
