Poor sleep quality negatively affects memory performance, and working memory in particular. We investigated sleep habits related to sleep quality including sleep duration, daytime nap duration, nap frequency, and dream content recall frequency (DCRF). Declarative working memory can be subdivided into verbal working memory (VWM) and visuospatial working memory (VSWM). We hypothesized that sleep habits would have different effects on VWM and VSWM. To our knowledge, our study is the first to investigate differences between VWM and VSWM related to daytime (...) nap duration, nap frequency, and DCRF. Furthermore, we tested the hypothesis that the effects of duration and frequency of daytime naps and DCRF on VWM and VSWM differed according to sex. We assessed 779 healthy right-handed individuals (434 males and 345 females; mean age: 20.7 ± 1.8 years) using a digit span forward and backward VWM task, a forward and backward VSWM task, and sleep habits scales. A correlation analysis was used to test the relationships between VWM capacity (VWMC) and VSWM capacity (VSWMC) scores and sleep duration, nap duration, nap frequency, and DCRF. Furthermore, multiple regression analyses were conducted to identify factors associated with VWMC and VSWMC scores and to identify sex-related differences. We found significant positive correlations between VSWMC and nap duration and DCRF, and between VWMC and sleep duration in all subjects. Furthermore, we found that working memory capacity (WMC) was positively correlated with nap duration in males and with sleep duration in females, and DCRF was positively correlated with VSWMC in females. Our finding of sex-related differences in the effects of sleep habits on WMC has not been reported previously. The associations between WMC and sleep habits differed according to sex because of differences in the underlying neural correlates of VWM and VSWM, and effectiveness of the sleep habits in males and females.

The sophisticated function of the central nervous system (CNS) is largely supported by proper interactions between neural cells and blood vessels. Accumulating evidence has demonstrated that neurons and glial cells support the formation of blood vessels, which in turn, act as migratory scaffolds for these cell types. Neural progenitors are also involved in the regulation of blood vessel formation. This mutual interaction between neural cells and blood vessels is elegantly controlled by several chemokines, growth factors, extracellular matrix, and adhesion molecules (...) such as integrins. Recent research has revealed that newly migrating cell types along blood vessels repel other preexisting migrating cell types, causing them to detach from the blood vessels. In this review, we discuss vascular formation and cell migration, particularly during development. Moreover, we discuss how the crosstalk between blood vessels and neurons and glial cells could be related to neurodevelopmental disorders. (shrink)

This article extends the concept of symmetry to ethics. Using the case of canola in Canada, the authors argue that grades and standards simultaneously subject humans and nonhumans to rites of passage that test their "goodness. " Then, they further develop a tentative typology of standards. The authors argue that these standards allow something resembling the neoclassical market to be established, create the conditions for economic analysis, and allocate power among human actors.

In nature, cells face a variety of stresses that cause physical damage to the plasma membrane and cell wall. It is well established that evolutionarily conserved cell cycle checkpoints monitor various cellular perturbations, including DNA damage and spindle misalignment. However, the ability of these cell cycle checkpoints to sense a damaged plasma membrane/cell wall is poorly understood. To the best of our knowledge, our recent paper described the first example of such a checkpoint, using budding yeast as a model. In (...) this review, we will discuss this important question as well as provide hypothetical explanations to be tested in the future. (shrink)

The earliest Chinese record of the maritime relations between India and China can be found in the “History of the Former Han Dynasty” (Chien Han-shu) which covers the period from B.C. 206 to A.D. 23. In its chapter (28b) on geography it is stated that ever since the time of the Emperor Wu (Wu Ti, B.C. 14087) the country called Huang-chih has sent tribute to the Chinese court, which in turn dispatched envoys to this remote country. Huang-chih has been identified (...) by many scholars with Kāñcī (Conjeeveram) on the east coast of South India. It is recorded that there were chief interpreters belonging to the Yellow Gate (the office of eunuchs serving in the palace) who went to sea to buy bright pearls, opaque glasses and other rare articles, taking with them from China gold and various kinds of silk for exchange.

We proposed the Standards of Conducts to provide a general framework that will serve as the basis for guiding each biostatistician and stem cell researcher to formulate their personal standards, rather than as rules with which they are required to comply. Given the responsibility and characteristics of their work, they are expected to maintain independence and work autonomously as professionals. Each of the Standards of Conducts comprises a preamble, mission and values to uphold, Standards of Conducts, and background. When one (...) internalizes “self-formulated” standards, to make excuses for oneself would be akin to a self-betrayal; responsible actions can be anticipated. If one begins and continues to consider “who I am and what do I work for,” this will become their inner energy, and a source of motivation and pride to inspire oneself. In addition, this aspirational style might help citizens to recognize the autonomous stance of the professional body and that they share the same values. (shrink)

The planet is experiencing a deep metamorphosis. The pressure that is being generated nowadays on the living can be felt in a human lifetime. The extreme speed of climate change and its impact on our ecosystem can no longer be ignored. When looking at the phenomenon of ecological resilience, we notice that after a disturbance, a shock on an ecosystem, like the burning of a forest, the resilient system rebuilds itself but not exactly as it was before, surprisingly new species (...) grow. In social systems, humans have the capacity to anticipate, adapt and invent new patterns of behaviours. In a world where everything is uncertain, moving, shifting, we are making an artistic proposal as an open dynamic system. We are developing two versions of the same HALO project to be presented on the sea and in public places. (shrink)

KM (Knowledge Management) systems have recently been adopted within the realm of enterprise management. On the other hand, data mining technology is widely acknowledged within Information systems' R&D Divisions. Specially, acquisition of meaningful information from Web usage data has become one of the most exciting eras. In this paper, we employ a Web based KM system and propose a framework for applying Web Usage Mining technology to KM data. As it turns out, task duration varies according to different user operations (...) such as referencing a table-of-contents page, down-loading a target file, and writing to a bulletin board. This in turn makes it possible to easily predict the purpose of the user's task. By taking these observations into account, we segmented access log data manually. These results were compared with results abstained by applying the constant interval method. Next, we obtained a segmentation rule of Web access logs by applying a machine-learning algorithm to manually segmented access logs as training data. Then, the newly obtained segmentation rule was compared with other known methods including the time interval method by evaluating their segmentation results in terms of recall and precision rates and it was shown that our rule attained the best results in both measures. Furthermore, the segmented data were fed to an association rule miner and the obtained association rules were utilized to modify the Web structure. (shrink)

While much has been written about the uniquely Hawaiian take on the category “local” – usually in terms of resistance to colonization, the alternative or counterhegemonic – little has been written about “haole”, the trope that served to silhouette the “local” and has evolved in dialectical opposition to it. A term that emerged during the plantation era to represent working-class immigrant workers mostly from Asia, “local” is constructed by exclusion. It has evolved to represent solidarity against all “external forces” controlling (...) Hawai'i from without, such as land development, tourism and the military – all readily equated with haole, the visible sign of whiteness. The prevalence of the prescription “local vs. haole” in contemporary Hawai'i begs an inquiry into other interpretations that are being suppressed. This paper explores some suppressed histories, imaginings and subconscious aspects of identity in Hawai'i through the figure of the white person whose parents – and possibly great-great-great-grandparents – were born and raised in Hawai'i.

The form of higher plants is largely dependent upon cell division and expansion patterns. Taking a genetic approach, Takahashi et al.(1) have identified a regulatory molecule in Arabidopsis thaliana called DIMINUTO (DIM), which is involved in determining the degree and direction of plant cell expansion. Their extensive characterization of a dim mutant suggested a direct involvement of the DIM gene in regulating cell elongation, perhaps by modulating the expression of structural genes which determine the orientation and elasticity of the cell (...) wall.

The purpose of this paper is to highlight the ontological character of Friendship in Aquinas. The originality of Aquinas's theory is found in the ontological foundation expressed by Neoplatonic concepts (unio, unitas, communicatio). By integrating such Neoplatonic concepts with his analysis on the transcendentals(aliquid, unum), I will make a new ontological foundation to the theory of amicitia. In order that a man is a one (unum), he must establish himself as something different (aliud quid) in the midst of the relationship (...) with others and then has to return to himself. So long as he stays self-contained without moving outward, he cannot constitute himself as an independent being which is different from other beings (aliquid). The ontological oneness (unitas) as an independent rational substance makes it possible for a man to form the mutual relationship of unity (unio) without losing himself in the midst of the deep relationship with someone else.

What Does Only Assert and Entail? This paper investigates the semantics of English only and two equivalent expressions in Japanese -dake and -shika, giving attention to two aspects: the debate over the status of two propositions that are involved in the use of ONLY expressions and the semantic and pragmatic differences among ONLY items, if any. We claim that a sentence with ONLY expressions entails both the affirmative and negative propositions. This view raises issues with Horn's original claim as well (...) as van Rooij and Schulz's while supporting Atlas and Horn. We claim then that the difference in strength between the affirmative and negative propositions emerges from what is asserted by that sentence. One of the bases for our claim is that there is a significant difference in behavior between entailment and assertion of a given sentence, following Horn. This difference explains the difference between -dake on the one hand and -shika and -only on the other: -dake differs from only and -shika in that it asserts the affirmative proposition while -shika and only asserts the negative proposition.

Social dilemmas, in which individually selfish behavior leads to collectively deficient outcomes, continue to be an important topic of research because of their ubiquity. The present research with Japanese participants replicates, with slight modifications, public goods games previously run in the United States. In contrast to recent work showing profound cross-cultural differences, the results of two studies reported here show remarkable cross-cultural similarities. Specifically, results suggest that (1) as in the U.S., allowing incremental commitment to a public good is effective (...) at eliciting contributions, (2) individual differences in trust affect contributions, (3) the distribution of player types in the U.S. and Japan are very similar, and (4) the dynamics of play in the public goods games used here are strikingly parallel. These results are discussed in the context of the relationship between cross-cultural differences and economic institutional environments. (shrink)

In recent years several books by major figures in Japan's modern philosophical tradition have appeared in English, exciting readers by their explorations of the borderlands between philosophy and religion. What has been wanting, however, is a book in a Western language to elucidate the life and thought of Nishida Kitaro, Japan's first philosopher of world stature and the originator of what has come to be called the Kyoto School. No one is more qualified to write such a book than Nishitani (...) Keiji, whose lifetime coincides with the rise and flowering of the Kyoto School and whose own critical contribution to Japanese thought has been so important. _Nishida Kitaro_ is a translation of essays Nishitani wrote about his teacher from 1936 to 1968 and published as a book in 1985. This series of meditations by one master on another provides a remarkable, living portrait of Nishida the person and conveys the enthusiasm he aroused in his students. Examining Nishida's most important work, _An Inquiry into the Good_, Nishitani penetrates to the core of his thought and presents it in language that is a marvel of clarity. (shrink)

One’s generosity to others declines as a function of social distance, which is known as social discounting. We examined cultural similarities and differences in social discounting and the mediating roles of the two aspects of interdependence (self-expression and distinctiveness of the self) as well as the two aspects of independence (harmony-seeking and rejection avoidance). Using the same procedure that previous researchers used to test North Americans, Study 1 showed that compared to North Americans, Japanese discount more steeply a partner’s outcomes (...) compared to their own future outcomes, whereas the decrease in the subjective value of the partner’s outcomes accelerates less as a function of social distance. To examine the cultural similarities and differences in social discounting in more detail, Study 2 tested Japanese and Germans and found that the hyperbolic with exponent model fitted the participants’ discounting behaviors better than the other models, except for the loss condition in Germans where the utility of the q-exponential model was indicated. Moreover, although the social discounting rate was higher in Japanese than in Germans, the cultural difference was limited to the gain frame. However, the decline in a person’s generosity accelerated less as a function of social distance in Japanese than in Germans. Furthermore, the cultural difference in the social discounting in gains was mediated by the level of harmony-seeking, which was higher in Germans than in Japanese. Implications for individuals’ generosity against the backdrop of cultural characteristics are discussed. (shrink)

In this article I examine Lavoisier's collaboration with his wife in the translation of Kirwan's An essay on phlogiston into French (Essai sur le phlogistique, 1788). This translation is a kind of counter attack by the school of French scholars around Lavoisier. Mrs Lavoisier is generally considered only to have translated Kirwan's book, not to have refuted it. Through a detailed analysis of the translation, of her manuscripts, and of other documents of the period, I conclude that Mrs Lavoisier not (...) only actively attacked the doctrine of phlogiston in her translation, but in the notes and preface to it as well. In addition to her high-level knowledge of chemistry, her close scientific relationship with her husband should be noted. In the first three parts of the translation, the two shared the work between them, in order to convine the readers. A show that Mrs Lavoisier advocated the study of gases from the point of view of their motions, and that she always believed that her husband's theory would prevail. Moreover, Lavoisier assessed his wife's talent at its true value. (shrink)

The title of my paper may look odd. If one is questioned “What is a dog?”, everyone could give a more or less valid answer. But to the question “What is not a dog?”, there can be innumerable answers which may be correct, but mostly quite unhelpful. Provisionally, what I intend to do under this title is to consider what we should not hold time to be. Through the history of ideas we meet various opinions and theories concerning what time (...) is. But it seems to me that most of them are not adequate enough, though each has its reason and often profound import as well. So I would like here to make a proposal for reconsidering how time appears in our life and thinking. (shrink)
