Multiple comparisons in two-factor testing of psychophysical thresholds by the delta test method

We propose an algorithm of multiple comparisons in two-factor testing of psychophysical thresholds. We use logistic regression combined with guessing rate and adopt the step-down procedure with Ryan–Einot–Gabriel–Welsch (REGW) significance levels for multiple test. We test hypotheses of main effects and interaction in two-factor problem by using the delta test statistics.     

Does Internet use provide a deeper sense of political empowerment to the Less Educated?

In politics, there is an offline power imbalance between the Educated and the Less Educated caused, in part, by the fact that those individuals with more extensive levels of education are more equipped to influence the political process. This study analyses the impact of Internet use on this imbalance and investigates whether the disparity remains intact in the Digital Age. Accessibility to the Internet is somewhat agnostic to one’s education and may be a quick and cost-effective tool to affect the political process. This study employs the concept of online political efficacy (OPE), which is likely to impact online political participation (OPP), to test whether Internet use provokes a sense of political effectiveness in the less educated to a greater extent than those more educated. Internet Service Types, particularly social media, were found to be positively associated with OPE to a much greater extent among the less educated. These findings indicate that, as a result of an enhanced positive perception of the Internet from using the Internet Service Types, the less educated are likely to feel empowered to affect the political process to a greater degree than the educated. Such use, in turn, is more likely to lead the less educated to OPP. This flow in the context of Internet use and education levels was presented in the framework of the O-S-R-O-R model of communication effects. As such, Internet use has the potential to contribute toward an equalization of the offline power imbalance.     

Does greater product information actually inform consumer decisions? The relationship between product information quantity and diversity of consumer decisions

For many consumer goods, the advent of online markets dramatically increases the amount of information available about products’ different features and qualities. Although numerous studies have investigated the effects of information quantity on individual-level decisions, it is still unknown how the amount of attribute information affects group-level patterns of behavior, particularly when consumers are also aware of a choice’s popularity. In the present studies, we hypothesized that when attribute information increases, it may exceed the individual’s cognitive capacity to process this information, and as a result conformity - choosing the most popular item - becomes more likely. In this study, we first examined empirical data collected from human subject experiments in a simulated online shopping experience, and then developed an agent-based model (ABM) to explore this behavioral clustering. Both studies confirmed our primary hypotheses, and the ABM shows promise as a tool for exploring extensions of these ideas.     

What the Japanese have learned from strategic alliances

The major vehicle manufacturers are facing an increasingly turbulent environment. A depressed world economy, rapidly changing technologies and the move towards globalization have brought strong challenges to the key players. One response to these conditions has been the formation of various types of collaborative ventures, in particular, strategic alliances. This article explores the lessons learnt by Japanese companies involved in strategic alliance activity. The nature of Japanese collaborative activity has changed in every decade since the 1950s, from being concerned primarily with gaining technological know-how from overseas to focusing on growing sales in a world market. Because no manufacturer, however large, can take on the huge investment required to dominate the global market, alliance activity is forecast to grow in importance.     

Globalization and National Identity in Japan

Abstract: Globalization and national identity are two separate but important concepts in contemporary sociology; however, neither is well grounded. There is little consensus. Yet we need to establish a foundation for talking about globalization and national identity and the relationship between them. By reviewing literature, this paper presents many sides of the related controversies. Globalization can be interpreted from many different perspectives: economic, social, psychological, political, even philosophical. There is little argument that globalization is now a major characteristic of our daily lives. Identity had its beginnings in psychology and was then superimposed upon social systems, thereby explicating local, regional and national identities: Who are we? We are like those people, but unlike those other people. When considering complex concepts, we need to ask appropriate questions of both parents and their children (due to socialization). In the research study described in this paper, two sample data sets from Japan were used (N = 2,164), both employing an identical questionnaire: (a) a nationwide survey of parents and their children aged 15 through 17; and (b) a nationwide survey of adults. The two stage stratified sampling method was used. The study revealed that Japanese children had more positive and open‐minded attitudes toward “others” than did their parents and older adult groups. One's generation has an important impact on national identity among the Japanese. The findings also indicate that Japan is not a nation‐state in which national identity plays a particularly significant role. The study also suggested numerous opportunities for future research.
