BackgroundAlthough, moral distress presents a serious problem among critical care nurses in many countries, limited research has been conducted on it. A validated scale has been developed to evaluate moral distress and has enabled cross-cultural comparison for seeking its root causes.Research aimsThis study aimed to (1) clarify the current status of moral distress among nurses who worked in critical care areas in Japan, (2) compare the moral distress levels among nurses in Japan with previously reported results from the United States (...) (US), and (3) explore the factors associated with moral distress.Research designA nationwide cross-sectional study was conducted.Participants and research contextWe conducted a self-administered questionnaire survey using the Measure of Moral Distress–Healthcare Professionals (MMD-HP) among critical care nurses who were randomly selected from hospitals across Japan. The mean differences between the two countries were compared using a Student's t-test with summary statistics. The factors associated with higher levels of moral distress were examined using a multiple regression analysis.Ethical considerationsThe study was approved by the Ethics Committee of the Tokyo Medical and Dental University (approval nos. M2018-214 and M2019-045).ResultsWe obtained 955 valid responses from 94 facilities. In Japan, the items with the highest moral distress scores were those related to aggressive/inappropriate treatment. The total MMD-HP score was significantly higher in Japanese nurses compared to US nurses (122.8 ± 70.8 vs 112.3 ± 73.2). Some factors, such as leadership experience, were associated with higher moral distress.DiscussionThe top root causes of moral distress were similar to potentially inappropriate treatments in both countries.ConclusionThis study revealed the factors associated with higher moral distress and its characteristics in each country. These results can be used for reducing moral distress in the future. (shrink)

Background:Moral distress has various adverse effects on nurses working in critical care. Differences in personal values, and between values and self-perception of behaviour are factors that may cause moral distress.Research aims:The aims of this study were (1) to identify ethical values and self-perception of behaviour of critical care nurses in Japan and (2) to determine the items with a large difference between value and behaviour and the items with a large difference in value from others.Research design:A nationwide, cross-sectional study was (...) conducted.Participants and research context:We developed a self-administered questionnaire with 28 items, which was completed by 1014 critical care nurses in Japan. The difference between value and self-perception of behaviour was calculated from the score of each value item minus the score of each self-perception of behaviour item. The size of the difference in value from the others was judged by the standard deviation of each item.Ethical considerations:The study was approved by the Ethics Committee of the Tokyo Medical and Dental University (approval nos. M2018-214, M2019-045).Results:The items with a large difference between value and behaviour sources were related to the working environment and decision-making support. The items with a large difference in value from others were related to hospital management and disclosure of information to patients.Discussion:Improving the working environment for nurses is important for reducing moral distress. Nurses are faced with a variety of choices, including advocating for patients and protecting the fair distribution of medical resources, and each nurse’s priorities might diverge from those of other team members, which can lead to conflict within the team.Conclusion:This study revealed items with particularly high risks of moral distress for nurses. The results provide foundational information that can guide the development of strategies to mitigate moral distress. (shrink)

Life is short and transient--Japanese people call this sentiment mujokan. However, what if we could sweep away the "despair" looming over the present age by proactively accepting this mujo (transience)? Perusing the thought of mujo from the perspectives of philosophy, literature, art and religion, Takeuchi delves into the view of life and death unique to the Japanese people who have shared "grief" and "pain" with each other, as well as into the very core of their underlying spirit." -- Publisher's (...) description.

In this article, we develop and clarify some of the basic combinatorial properties of the new notion of n-dependence recently introduced by Shelah. In the same way as dependence of a theory means its inability to encode a bipartite random graph with a definable edge relation, n-dependence corresponds to the inability to encode a random -partite -hypergraph with a definable edge relation. We characterize n-dependence by counting φ-types over finite sets, and in terms of the collapse of random ordered -hypergraph (...) indiscernibles down to order-indiscernibles. (shrink)

We study model companions of theories extending the graph axioms. First we prove general results concerning the existence of the model companion. Then, by applying these results to the case of graphs, we give a series of companionable and non‐companionable examples.

A milestone in Japan's post-war philosophical thought and a dramatic turning point in Tanabe's own philosophy, _Philosophy as Metanoetics_ calls for nothing less than a complete and radical rethinking of the philosophical task itself. It is a powerful, original work, showing vast erudition in all areas of both Eastern and Western thought.

A total of 366 UK children in four different schools, one in Wales, one in Northern Ireland, and two in England, were asked to respond to 20 potentially stressful life experiences. Each event was rated on a scale ranging from 7 to 1 , and the scale value and interquartile range were calculated. In addition, whether or not a given event was actually experienced was noted. Across the groups, there was a very high degree of agreement on all three measures, (...) the median correlations being 0.95 for scale values, 0.70 for interquartile ranges, and 0.92 for incidence. Furthermore, the pooled UK results were found to correlate equally closely with the figures previously obtained in the USA and five other countries. The possibility of a prevalent ‘culture of childhood’, cutting across geo‐political boundaries and ethnic groupings, appears to receive further support. (shrink)

We introduce several concepts concerning the indiscernibility of trees. A tree is by definition an ordered set such that, for any a∈O, the initial segment {b∈O:b (...) A of the form η∈O, where O is a tree, and aη labeled by η is an element in M. Such a set A is also called a tree in this paper. We study the indiscernibility of trees A in general settings and apply the obtained results to the study of unstable theories. (shrink)

Experimental phenomenology has demonstrated that perception is much richer than stimulus. As is seen in color perception, one and the same stimulus provides more than several modes of appearance or perceptual dimensions. Similarly, there are various perceptual dimensions in form perception. Even a simple geometrical figure inducing visual illusion gives not only perceptual impressions of size, shape, slant, depth, and orientation, but also affective or aesthetic impressions. The present study reviews our experimental phenomenological work on visual illusion and experimental aesthetics, (...) and examines how aesthetic preference is influenced by stimulus factors determining visual illusions including anomalous surface and transparency as well as geometrical illusion. Along with line figures producing geometrical illusions, illusory surface figures inducing neon color spreading and transparency effects were used as test patterns. Participants made both of psychophysical judgments and of aesthetic judgments for the same test pattern. Both of geometrical illusions and aesthetic preferences were found to change similarly as a function of stimulus variables such as the number of filling lines and the size ratio of the inner and outer figural components. Also, following specific stimulus variables such as lightness contrast ratio and spatial interval between inducing figural elements (so called ``packmen''), strong effects of color spreading and transparency were accompanied with strong preferences. It seems that the paradigm to investigate aesthetic phenomena along with perceptual dimensions is useful to bridge the gap between experimental phenomenology and experimental aesthetics. (shrink)

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.

Nielsen's covert REM process model explains much of the mentation found in REM and NREM sleep, but stops short of postulating an interaction of waking cognitive processes with the dream mechanisms of REM sleep. It ranks with the Hobson et al. paper as a major theoretical advance. The Solms article does not surmount the ever-present problem of defining dreams in a manner conducive to advancing dream theory. Vertes & Eastman review the REM sleep and learning literature, but make questionable assumptions (...) in doing so. [Hobson et al.; Nielsen; Solms; Vertes & Eastman]. (shrink)
