In empirical software engineering research, there is an increased use of questionnaires and surveys to collect information from practitioners. Typically, such data is then analyzed based on overall, descriptive statistics. Overall, they consider the whole survey population as a single group with some sampling techniques to extract varieties. In some cases, the population is also partitioned into sub-groups based on some background information. However, this does not reveal opinion diversity properly as similar opinions can exist in different segments of the population, whereas people within the same group might have different opinions. Even though existing approach can capture the general trends there is a risk that the opinions of different sub-groups are lost. The problem becomes more complex in case of longitudinal studies where minority opinions might fade or resolute over time. Survey based longitudinal data may have some potential patterns which can be extracted through a clustering process. It may reveal new information and attract attention to alternative perspectives. We suggest using a data mining approach to finding the diversity among the different groups in longitudinal studies (agile skeptics). In our study, we show that diversity can be revealed and tracked over time with the use of clustering approach, and the minorities have an opportunity to be heard.

The IPCC's standing on the anthropogenic warming is discussed in this article. The differences between the climate alarmist and skeptics have been addressed in terms of scientific and policy stand point of view. The political and economical significances of climate change have been discussed, too. Although atmospheric temperature and rainfall precipitation are two most important factors in the climate change, most of the recent attentions have drawn on mainly temperature and $CO_2$ issue. In spite of argues on the uncertainty in anthropogenic warming related to $CO_2$, the inevitable climate change should correspondingly change the humanity in near feature.

Consumer responses to 3D online shopping malls are influenced by their attitudes toward technology. This study examines the consumer differentiation according to technology readiness, compares customers with different technology readiness in terms of their perceived telepresence and e-loyalty, and examines the effect of their perceived telepresence on their e-loyalty. Samples from 300 females aged 21 to 39 were used for the final analysis. The results are as follows. First, consumers were classified into three groups, Explorers (N=72), Pioneers (N=105), and Skeptics (N=123), through factor analysis and k-means cluster analysis. Second, the Explorers evaluated the telepresence of the 3D online shopping mall higher than any other group. The Skeptics presented lower e-loyalty and perceived less telepresence in the 3D online shopping mall than the other two groups. Finally, telepresence had a significant influence on e-loyalty, as identified by the regression analysis. This verifies the effectiveness of 3D technology adopted or to be adopted by online shopping malls and demonstrates that 3D shopping malls can be a strategic alternative in the online shopping sector where competition is fierce. The results show that online shopping malls should focus on establishing 3D shopping environments with further effort to utilize the technology.

Social media holds the potential to facilitate vertical political communication by giving citizens the opportunity to interact directly with their representatives. However, skeptics claim that even when politicians use "interactive media," they avoid direct engagement with constituents, using technology to present a façade of interactivity instead of a genuine dialogue. This study explores how elected officials in three regions of the world are using Twitter to interact with the public. Using the Twitter activity of 15 officials over a period of six months, we show that in addition to the structural features of Twitter that are designed to promote interaction, officials rely on language to foster or to avoid engagement. We also provide evidence that the existence of interactive features does not guarantee interactivity.

This study divides consumers into groups according to the TRI(technology readiness index) in order to (md out the characteristics of each consumer group, and attempts to examine how the frequency of shopping and the TRI affect service quality of and satisfaction at the internet apparel shopping sites. An on-line survey was made to collect data, and the replies from 785 people, who had an experience of apparel shopping apparel on line, were used in the analysis. The research results are as follows: 1. The four factors of optimism, innovativeness, discomfort, and insecurity were identified from the TRI factor analysis, and the total variance was 58.88%. 2. The male group showed the higher TRI than the female group. Especially the factor of innovativeness was higher in the male group, indicating the male group's activeness in the use of technology. 3. Consumers were classified into five types in terms of the TRI: explorers, pioneers, skeptics, paranoids, and laggards. 4. Service quality had the greatest influence on consumers’satisfaction with the apparel shopping sites, and the frequency of purchase, optimism, and discomfort ranked next to service quality.

Because the mobile services is composed of heterogeneous attributes, it is hard to find out customer's potential needs and more difficult to analyze customer's satisfaction factors toward mobile services. Therefore, this study approached this issue from a new viewpoint and applied Kano Model in analyzing customer's satisfaction and dissatisfaction factors toward mobile services. By using Kano Model, it tried to find out how differently customers perceive the mobile services. Firstly, we found out perception gaps of Korean and American customers toward mobile services. While Korean customers perceived most mobile services as indifferent service attributes, American customers perceived them as attractive service attributes. We could find main reasons of these perception differences from different national backgrounds and adoption rates of smart phones between two countries. Secondly, based on TRI scores, we categorized subjects into four groups and named as Pioneers, Explorers, Skeptics and Laggards. And then we examined the perception differences to mobile services among four groups. We found that there were no significant perception differences among four groups.
