This chapter, which describes the spatiality of conscious phenomena, such as colours and sounds, addresses James Gibson’s ecological approach to confirm and develop further the Husserlian phenomenological view of colours and sounds. The ecological approach to perception could be regarded as an attempt to undertake empirical research corresponding to the phenomenological insight of perception. In this context, in addition to the Husserlian concept of “adumbration” and the Gibsonian concept of “ecological optics,” the differentiation of various modes of colour appearances, which (...) David Katz explicated, is focused on, developed and applied further to the phenomena of sounds. On the basis of these discussions, the multi-dimensional character of colours and sounds are explicated, and traditional views on colours and sounds, which neglect this character, are criticized. The concept of multi-dimensionality discovers the remarkable diversity of the world of colours and sounds, which demonstrate the diversity and multiple dimensionality of the field of consciousness.

Discovery of representative Web pages regarding specific topics is important for assisting users' information retrieval from the Web. Researches on Web structure mining, whose goals are to discover or to rank important Web pages based on the graph structure of hyperlinks, have been very active recently. A complete bipartite of Web graph, which is composed of centers (containing useful information regarding specific topic) and fans (containing hyperlinks to centers), can be regarded as a Web community sharing a common interest. Although (...) Murata's method for discovering Web communities is a simple method for finding related Web pages, it has the following weaknesses: (1) since the number of centers increases monotonously, pages irrelevant to the members of Web communities may be added in the process of discovery, and (2) since the number of fans decreases monotonously according as the number of centers increases, the method may suffer topic drift. This paper describes an improved method for refining Web communities in order to acquire representative Web pages of the topics of input Web communities. The method is based on the assumption that most of the fans contain hyperlinks pointing to representative pages regarding their topic, and that hyperlinks to the pages of the same quality often co-occur. In our new method, both fans and centers are renewed iteratively by the result of the majority vote of the members of previous Web community. Results of our experiments show that the new method has abilities of finding desirable pages for several topics. (shrink)

This paper proposes a method for discovering Web communities. A complete bipartite graph K i, j of Web pages can be regarded as a community sharing a common interest. Discovery of such community is expected to assist users’ information retrieval from the Web. The method proposed in this paper is based on the assumption that hyperlinks to related Web pages often co-occur. Relations of Web pages are detected by the co-occurrence of hyperlinks on the pages which are acquired from a (...) search engine by backlink search. In order to find a new member of a Web community, all the hyperlinks contained in the acquired pages are extracted. A page which is pointed by the most frequent hyperlinks is regarded as a new member of the community. We have build a system which discovers complete bipartite graphs based on the method. Only from a few URLs of initial community members, the system succeeds in discovering several genres of Web communities without analyzing the contents of Web pages. (shrink)

A sense of agency (SoA) is the experience of subjective awareness regarding the control of one’s actions. Humans have a natural tendency to generate prediction models of the environment and adapt their models according to changes in the environment. The SoA is associated with the degree of the adaptation of the prediction models, e.g., insufficient adaptation causes low predictability and lowers the SoA over the environment. Thus, identifying the mechanisms behind the adaptation process of a prediction model related to the (...) SoA is essential for understanding the generative process of the SoA. In the first half of the current study, we constructed a mathematical model in which the SoA represents a likelihood value for a given observation (sensory feedback) in a prediction model of the environment and in which the prediction model is updated according to the likelihood value. From our mathematical model, we theoretically derived a testable hypothesis that the prediction model is updated according to a Bayesian rule or a stochastic gradient. In the second half of our study, we focused on the experimental examination of this hypothesis. In our experiment, human subjects were repeatedly asked to observe a moving square on a computer screen and press a button after a beep sound. The button press resulted in an abrupt jump of the moving square on the screen. Experiencing the various stochastic time intervals between the action execution button-press) and the consequent event square jumping caused gradual changes in the subjects' degree of their SoA. By comparing the above theoretical hypothesis with the experimental results, we concluded that the update (adaptation) rule of the prediction model based on the SoA is better described by a Bayesian update than by a stochastic gradient descent.

PurposeThe purpose of this paper is to analyse incidents of personal information leakage in Japan based on Japanese socio‐cultural characteristics of information privacy and to consider how best to develop an effective personal information protection policy that conforms to Japanese situations as well as to the global requirement of personal information protection.Design/methodology/approachAfter describing recent incidents of personal information leakage in Japan, the paper examines the defects of the Act on Protection of Personal Information that permit these incidents to continue. Subsequently, (...) these incidents and the responses of the Japanese people in a manner that reflects the unique Japanese socio‐cultural characteristics of information privacy are analysed. Finally, the paper proposes a revision of APPI that conforms to these Japanese socio‐cultural characteristics as well as to the global requirement for personal information protection.FindingsPersonal information leakage cases and social responses in Japan reflect three Japanese socio‐cultural characteristics: Uchi/Soto awareness, insular collectivism and Hon'ne/Tatemae tradition. An effective law protecting personal information in Japan's cultural environment cannot be made simply by copying the privacy protection laws in western nations. Instead, legal protection of personal information should be drafted that reflects and takes into account these socio‐cultural characteristics.Originality/valueThis paper conducts analysis of incidents of personal information leakage in Japan based on Japanese socio‐cultural characteristics. A revision of APPI is proposed on the basis of the analysis. The paper's analysis and proposal would provide a good clue to develop effective measures to protect personal information and the right to information privacy in the global, multicultural information society.

PurposeThis paper aims to deal with the attitudes towards and social impact of Edward Snowden’s revelations in Japan, taking the Japanese socio-cultural and political environment surrounding privacy and state surveillance into account.Design/methodology/approachA questionnaire survey of 1,820 university students and semi-structured follow-up interviews with 56 respondents were conducted, in addition to reviews of the literature on privacy and state surveillance in Japan. The outcomes of the survey were statistically analysed, and qualitative analyses of the interview results were also performed.FindingsSnowden’s revelations have (...) had little influence over Japanese youngsters’ attitudes towards privacy and state surveillance, mainly due to their low level of awareness of the revelations and high level of confidence in government agencies.Practical implicationsThe study results imply a need for reviewing educational programmes for civic education in lower and upper secondary education.Social implicationsThe results of this study based on a large-scale questionnaire survey indicate an urgent necessity for providing Japanese youngsters with opportunities to learn more about privacy, liberty, individual autonomy and national security.Originality/valueThis study is the first attempt to investigate the social impact of Snowden’s revelations on Japanese youngsters’ attitudes towards privacy and state surveillance as part of cross-cultural analyses between eight countries.

Against the Newtonian view of color, according to which the world is colorless and colors are subjective sensations, phenomenologists keep insisting that colors are in the world. In order to defend this view of the “being in the world” of colors, this paper tries to elucidate the essential spatiality of colors on the basis of James’s thesis of the intrinsic spatiality of sensation, Katz’s phenomenological description of various spatial characters of color, and Gibson’s ecological optics. The noticeable correspondence between Katz’s (...) phenomenology and Gibson’s ecological optics indicates to us a possible way to an ecological phenomenology of colors. (shrink)

Purpose A survey of the attitudes of students in eight countries towards the revelations of mass surveillance by the US’ NSA and the UK’s GCHQ has been described in an introductory paper and seven country-specific papers. This paper aims to present a comparison of the results from these countries and draws conclusions about the similarities and differences noted. Design/methodology/approach A questionnaire was deployed in Germany, Japan, Mexico, New Zealand, The People’s Republic of China, Spain, Sweden and Taiwan. The original survey (...) was in English, translated into German, Japanese and Chinese for relevant countries. The survey consists of a combination of Likert scale, Yes/no and free-text responses. The results are quantitatively analysed using appropriate statistical tools and the qualitative answers are interpreted. Findings There are significant differences between respondents in the countries surveyed with respect to their general privacy attitudes and their willingness to follow Snowden’s lead, even where they believe his actions served the public good. Research limitations/implications Owing to resource limitations, only university students were surveyed. In some countries, the relatively small number of respondents limits the ability to make meaningful statistical comparisons between respondents from those countries and from elsewhere on some issues. Practical implications Snowden’s actions are generally seen as laudable and having had positive results, among the respondents surveyed. Such results should give pause to governments seeking to expand mass surveillance by government entities. Originality/value There have been few surveys regarding attitudes to Snowden’s revelations, despite the significant press attention and political actions that have flowed from it. The context of attitudes to both the actions he revealed and the act of revelation itself is useful in constructing political and philosophical arguments about the balance between surveillance activity for state security and the privacy of individual citizens.

Through expanded access protocols, the Food and Drug Administration (FDA) allows patients with serious or immediately life-threatening diseases access to experimental drugs outside the clinical trial setting when no satisfactory alternative treatment is available. While the FDA has established a mechanism for providing patients with unapproved drug access, the regulations do not require the pharmaceutical company to provide the drug. The drug company’s permission to use its experimental drug is a necessary prerequisite to using the FDA’s expanded access mechanism. Increasingly, (...) drug companies are coming under scrutiny regarding the programs governing that decision-making power. Historically, disclosing whether a company has an expanded access program, and whether or how it would respond to an expanded access request, has been left to discretion of the drug companies themselves. Few manufacturers publish adequate expanded access protocols. As a result, patients were provided with little insight into how companies evaluate expanded access requests and are naturally skeptical as to the ethical integrity of the process. The recently passed 21st Century Cures Act changes that practice by requiring drug companies to have, and make publically available, their expanded access procedures including criteria for evaluating and responding to patient requests. In this article, we contend that complying with the new transparency provisions will require drug companies to respond to several unresolved expanded access issues. Namely, how to reconcile a patient’s desire to access lifesaving experimental therapies alongside the company and society’s interest in the efficient development of new drugs. Even more challenging, how can companies devise practices for evaluating and processing expanded access requests that also fairly and equitably acknowledge those concerns? In addressing these questions, this article explores the legal, regulatory, business, and societal influences that have shaped expanded access policies and practices. From there, we provide companies a framework that balances appropriately the desires of individuals and gaining the requisite approvals ensure access not just for one person but for society. (shrink)
