Cells utilize diverse organelles to maintain homeostasis and to respond to extracellular stimuli. Recently, multifaceted aspects of organelle stress caused by various factors have been emerging. The endosome is an essential organelle, functioning as the central hub for membrane trafficking in cooperation with the ubiquitin system. However, knowledge regarding endosomal stress, which refers to organelle stress of the endosome, is currently limited. We recently revealed ubiquitin‐mediated endosomal stress of early endosomes (EEs) and its responsive signaling pathways. These findings shed light (...) on the relevance of ubiquitin‐mediated endosomal stress to physiological and pathological processes. Here, we present a hypothesis that ubiquitin‐mediated endosomal stress may have significant roles in biological contexts and that ubiquitin‐specific protease 8 is a key regulator of ubiquitin clearance from EEs.

Background Although, 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 aims This 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 design A nationwide cross-sectional study was conducted. Participants and research context We 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 considerations The study was approved by the Ethics Committee of the Tokyo Medical and Dental University (approval nos. M2018-214 and M2019-045). Results We 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. Discussion The top root causes of moral distress were similar to potentially inappropriate treatments in both countries. Conclusion This 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.

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)

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)

In a typical reversal-learning experiment, one learns stimulus–outcome contingencies that then switch without warning. For instance, participants might have to repeatedly choose between two faces, one of which yields points whereas the other does not, with a reversal at some point in which face yields points. The current study examined age differences in the effects of outcome type on reversal learning. In the first experiment, the participants’ task was either to select the person who would be in a better mood (...) or to select the person who would yield more points. Reversals in which face was the correct option occurred several times. Older adults did worse in blocks in which the correct response was to select the person who would not be angry than in blocks in which the correct response was to select the person who would smile. Younger adults did not show a difference by emotional valence. In the second study, the negative condition was switched to have the same format as the positive condition (to select who will be angry). Again, older adults did worse with negative than positive outcomes, whereas younger adults did not show a difference by emotional valence. A third experiment replicated the lack of valence effects in younger adults with a harder probabilistic reversal-learning task. In the first two experiments, older adults performed about as well as younger adults in the positive conditions but performed worse in the negative conditions. These findings suggest that negative emotional outcomes selectively impair older adults’ reversal learning. (shrink)

This article discusses three policy ideas that address the limitations of the traditional welfare state: universal basic income (UBI), universal basic services (UBS), and the social economy. As a lens from which to evaluate these policy alternatives, we develop a concept of active citizenship as an interactive and recursive process between people’s equal political influence and the institutional conditions in which they are placed. While the social policy discourse on active citizenship has centred on the debate between increasing individual responsibilities (...) or enhancing people’s capabilities, our conception recentres the political dimension of active citizenship as people’s capacity, not only to exercise individual self-determination, but also collective self-determination over shared conditions. We conclude that, in addition to the conditions for security and autonomy, opportunities for organised social cooperation are necessary to achieve a virtuous cycle between people’s political influence and the institutions that support it.

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)

Standard notions of democracy assume people’s equality. This poses a dilemma for conceptualising democracy in the context of caregiving and receiving among asymmetrically positioned people. One way to overcome this dilemma is to generalise dependency as a universal human condition. However, addressing how democracy is possible among unequally situated people is necessary for developing a distinctive theory of democracy that takes the fact of human dependency seriously. To this end, I develop an expanded conception of democracy that goes beyond the (...) individual exercise of voice to that of interacting with others according to an ethic of care that supports the autonomy of others. Drawing on Hannah Arendt’s notion of a ‘common world’ as a web of narratives arising from the complex interaction of plural perspectives, I argue that democracy conceived as ‘being part of the story’ can foster such an ethic. This has practical relevance for societies where the sites of social cooperation are shifting from employment to care. (shrink)
