For ${b \in {^{\omega}}{\omega}}$ , let ${\mathfrak{c}^{\exists}_{b, 1}}$ be the minimal number of functions (or slaloms with width 1) to catch every functions below b in infinitely many positions. In this paper, by using the technique of forcing, we construct a generic model in which there are many coefficients ${\mathfrak{c}^{\exists}_{{b_\alpha}, 1}}$ with pairwise different values. In particular, under the assumption that a weakly inaccessible cardinal exists, we can construct a generic model in which there are continuum many coefficients ${\mathfrak{c}^{\exists}_{{b_\alpha}, 1}}$ (...) with pairwise different values. In conjunction with these results, we give a generic model in which there are many Yorioka’s ideals ${\mathcal{I}_{f_\alpha}}$ with pairwise different covering numbers. (shrink)

We review some techniques and notions for quantum information theory. It is shown that the dynamical entropies is discussed and some numerical computations of these entropies are carried for several states.

We review some notions for general quantum entropies. The entropy of the compound systems is discussed and a numerical computation of the quantum dynamical systems is carried for the noisy optical channel.

In 2002, Yorioka introduced the σ-ideal ${{\mathcal {I}}_f}$ for strictly increasing functions f from ω into ω to analyze the cofinality of the strong measure zero ideal. For each f, we study the cardinal coefficients (the additivity, covering number, uniformity and cofinality) of ${{\mathcal {I}}_f}$.

Researchers have been interested in what retrieval process is responsible for overgeneral autobiographical memories (OGM) in depression. Previous cross-sectional studies demonstrated that, for negatively valenced cues, directly retrieved OGM, rather than generatively retrieved OGM, are associated with depression. However, longitudinal evidence of this relationship is still lacking and needs to be tested. We conducted a re-analysis of the online computerised memory specificity training (c-MeST) data to examine whether directly retrieved OGM for negative cues prospectively predicts high levels of depression 1 (...) month later. Participants who met the criteria of current major depressive disorders (N = 116; n = 58 in the c-MeST group and n = 58 in the control group) recalled autobiographical memories for positive and negative cues and judged each retrieval process (i.e. direct or generative). The results supported our prediction, and directly retrieved OGM for negative cues predicted high levels of depressive symptoms 1 month later even after controlling for the group effect, baseline depressive symptoms, executive functioning and rumination. Exploratory analysis showed that direct retrieval of specific memories prospectively predicted low levels of depression. These results support the theory that elevated accessibility of negatively valenced general memory representations is a vulnerability factor for depressive symptoms. (shrink)

Diogenes, Ahead of Print. The aim of this study is to elucidate the genesis of communality in the urban street. Although in the modern world cities have long been seen as research laboratories, in today’s context of globalization they are becoming more radical and dynamic; they are becoming experimental theatres of social change. Since the end of the twentieth century, the political and economic reorganization of the world order is producing dramatic changes in various societies throughout the globe. This is (...) bringing about changes which tend to standardize society and atomize individual subjects. These changes are seemingly connected, but they do exist alone, separately. In this complex situation, we are confronted with the fundamental question, how can people construct communality transcending differences among them? The present study looks for an answer to this question, paying special attention to collective violence in the urban street, where ‘emergent but real’ norms are constructed among the rioters and the communality genesis mechanism is activated. In order to make a case for this urban communality, the analysis focuses on events in the streets of Nairobi at the time of the Second Liberation of 1990s and during the Post-Election Violence of 2007–2008. People with different political and religious affiliation and ethnic identity were involved in violent urban riots. They were originally strangers, but they generated new social order and norms. In the street, they constructed and shared a provisional communality, which was emergent and fluid but also real and firm. (shrink)

A set F of Boolean functions is said to be functionally complete if every Boolean function is definable by combining functions in F. Post clarified when a set of Boolean functions is functionally complete (with respect to classical semantics). In this paper, by extending Post’s theorem, we clarify when a set of Boolean functions is functionally complete with respect to Kripke semantics.

Secreted signaling molecules act as morphogens to control patterning and growth in many developing tissues. Since locally produced morphogens spread to form a concentration gradient in the surrounding tissue, spreading is generally thought to be the key step in the non‐autonomous actions. Here, we review recent advances in tool development to investigate morphogen function using the role of decapentaplegic (Dpp)/bone morphogenetic protein (BMP)‐type ligand in the Drosophila wing disc as an example. By applying protein binder tools to distinguish between the (...) roles of Dpp spreading and local Dpp signaling, we found that Dpp signaling in the source cells is important for wing patterning and growth but Dpp spreading from this source cells is not as strictly required as previously thought. Given recent studies showing unexpected requirements of long‐range action of different morphogens, manipulating endogenous morphogen gradients by synthetic protein binder tools could shed more light on how morphogens act in developing tissues.

To understand the public opinion concerning the genethics in culturally different populations, we conducted two focus groups in Japan, with one focus group each in China and Panama between April 2008 and August 2009. Generally, the participants in Japan were more cautious to disclose their personal thinking in a clear manner. Most participants in China and Panama hoped to have children free from any genetic disease if at all possible. The major difference between China and Panama seems to be whether (...) or not they will accept the issue of genetic abortion. Compared to China and Panama, fewer participants accepted a reprogenetics procedure in Japan. ―A goal of genetic counseling is to reduce the number of patients of genetic disease‖ is supported to a greater degree in China and Panama than in Japan. Most participants in China as well as Panama, and fewer participants in Japan accepted the concept of sharing genetic information with relatives, even though it is useful for preventing a possible genetic risk. The difference of the answers for the questions is depending on the cultural and value diversity in each country, while some of them are related into a paucity of knowing the principle of biogenetics. Education as to medical genetics and the principle of bioethics is most important to make genetics more accessible to the general public. (shrink)

Vera Schwarcz's Place and Memory in the Singing Crane Garden examines the moral, philosophical, and historical meanings of a garden built by a Manchu Chinese prince, subsequently destroyed by British imperialists, commandeered by Red Guard radicals, and finally transformed into the grounds of an art museum. Reading Singing Crane Garden in the context of Schwarcz's previous writings on Chinese intellectuals and Jewish traditions, as well as insights provided by critical philosophers and geographers, this essay explores the moral and ethical dimensions (...) of locating history in specific “emplacements”. The argument begins by examining the phenomenology of place articulated by Edward Casey, weaves through discussions of Chinese spatiality, embodiment, and garden aesthetics, and comments on Schwarcz's study of broken monuments and stele through comparisons with Classical Chinese writers and the contemporary American poet Louise Glück. Comparisons are made between the destruction of the garden by the British forces of James Elgin, the murder of the journalist Thomas Bowlby, and the purging, imprisonment, torture, and brutality against scholars and intellectuals by the Red Guards under Mao. The essay closes with commentaries on Schwarcz's reflections concerning continuing global atrocities, and new insights into the ways that understanding landscape architecture as a form of history can bring meaning to questions of memory, loss, and the desire to evoke unrecoverable experiences.
