In simulation-based learning environments, 'unexpected' phenomena often work as counterexamples which promote a learner to reconsider the problem. It is important that counterexamples contain sufficient information which leads a learner to correct understanding. This paper proposes a method for creating such counterexamples. Error-Based Simulation (EBS) is used for this purpose, which simulates the erroneous motion in mechanics based on a learner's erroneous equation. Our framework is as follows: (1) to identify the cause of errors by comparing a learner's answer with (...) the problem-solver's correct one, (2) to visualize the cause of errors by the unnatural motions in EBS. To perform (1), misconceptions are classified based on problem-solving model, and related to their appearance on a learner's answers (error-identification rules). To perform (2), objects' motions in EBS are classified and related to their suggesting misconceptions (error-visualization rules). A prototype system is implemented and evaluated through a preliminary test, to confirm the usefulness of the framework. (shrink)

Modest difference in individual decisional skills may warrant substantial inequality in power. This claim has been illustrated in Ben Yashar and Nitzan (Economics Letters 174:93–95, 2019), applying the symmetric uncertain dichotomous choice setting and focusing on the skill-dependent (s-d) power of the decision-makers under the optimal decision rule. The same claim is valid when one focuses on the relationship between skill heterogeneity and the distribution of the second type of power, viz., the group members' marginal contribution (mc). This has been (...) shown in Ben Yashar et al. (Journal of Theoretical Politics 33(2):225–235, 2021), where mc has been formally related to s-d power. A preliminary study of the relationship between inequality of the distributions of the two measures has also been presented. The current paper considerably expands this investigation by applying simulations and sheds light on the reason for the increased inequality of the two types of power. Since reward (in terms of status, payment or both) depends on s-d power and mc, inequality of the distribution of rewards depends on the inequality of the two types of power. Comparison of the two types of power inequality is therefore interesting if one wishes to shed light on the role of the two types of power on reward inequality. In particular, the results of the comparison may clarify the effectiveness of the incentives to invest in skills, dependent on the prevailing norms and the institutional characteristics that determine the relationship between rewards and the two types of power. For this reason, the current study focuses on the comparison between inequality of s-d power and marginal contributions showing that, in small (large) groups, on average, the latter is more (less) unequal than the former and both are more unequal than the optimal weights of the decision-makers and much more unequal than their skills. The robustness of these findings is shown by applying alternative symmetric probability distribution functions. Another novel task undertaken in the current study is the sensitivity analysis of inequality of the power measures with respect to changes in the size of the group and the skills of the group members.

Environmental, physiological, and pathological stimuli induce the misfolding of proteins, which results in the formation of aggregates and amyloid fibrils. To cope with proteotoxic stress, cells are equipped with adaptive mechanisms that are accompanied by changes in gene expression. The evolutionarily conserved mechanism called the heat shock response is characterized by the induction of a set of heat shock proteins (HSPs), and is mainly regulated by heat shock transcription factor 1 (HSF1) in mammals. We herein introduce the mechanisms by which (...) HSF1 tightly controls the transcription of HSP genes via the regulation of pre‐initiation complex recruitment in their promoters under proteotoxic stress. These mechanisms involve the stress‐induced regulation of HSF1‐transcription complex formation with a number of coactivators, changes in chromatin states, and the formation of phase‐separated condensates through post‐translational modifications.

Transitioning from a company of individual contributors to an organization of leaders of leaders can be relatively straightforward. The organization must embrace the idea that leadership resides within every employee and continually cultivate leadership skills and abilities. It must anticipate that individuals will lose their bearings and reassure them that getting back in balance is only a thought away. For many, the shift to leaders of leaders requires daily leaps of faith rooted in wisdom; it also challenges ingrained individual or (...) cultural thinking habits. (shrink)

There is growing evidence that individuals with social anxiety show impaired cortisol recovery after experiencing social evaluative stressors. Yet, little is known regarding the cognitive processes underlying such impaired cortisol recovery. The present study examined the effect of post-event processing (PEP), referred to as repetitive thinking about social situations, on cortisol recovery following a social stressor. Forty-two non-clinical university students (23 women, 19 men, mean age = 22.0 ± 2.0 years) completed the Trier Social Stress Test (TSST), followed by a (...) thought sampling procedure which assessed the frequency of PEP reflecting the TSST. A growth curve model showed PEP and social anxiety interactively predicted cortisol recovery. In particular, PEP predicted impaired cortisol recovery in those with low levels of social anxiety but not in those with high levels of social anxiety, which contradicted the initial hypothesis. These findings suggest that PEP is differentially associated with cortisol recovery depending on levels of social anxiety. The possible mechanisms underlying these findings were discussed in terms of protective inhibition framework. (shrink)

This paper describes an automatic monitoring system that constantly checks partial update in Web pages and notifies them to a user. While one of the most important advantages of the WWW is update of Web pages, we need to constantly check them out and this task takes much cognitive load. Thus applications to automatically check update of Web pages have been developed, however they can not deal with partial update like update in a particular cell in a table in a (...) Web page. Hence we developed a automatic monitoring system that checks such partial update. A user can give a system regions in which he/she wants to know the update in a Web page as training examples, and it is able to learn rules to identify the partial update by classification learning. By this learning, a user do not need to directly describe the rules. We implemented our system and some executed examples were presented. (shrink)

The purpose of this paper is to analyze the financial turmoil of the US subprime loan crisis of mid-Noughties and to compare it with the Japanese asset bubble of late 1980s. While examining the two crises, it compares the monetary policies of both countries, focusing on the excess liquidity and expansion of bank loans that were seen. This paper develops several bubble indicators, including the ratio of real estate loans to total loans, the loan-to-GDP ratio, and housing affordability. In order (...) to develop these indicators, it is necessary to compare banking behavior in both Japan and the United States, as banks in both countries were making loans beyond the point of profit maximization. Property prices and monetary policy in both countries influenced banking behavior significantly. The bubble indicators developed in this paper can be used as early warning indicators for future bubbles. (shrink)

This paper explores the time-inconsistency problem of audience costs in international disputes. The nature of democracy makes it difficult for leaders to back down from earlier diplomatic positions in an international dispute, out of fear of domestic political costs. Few studies have addressed the temporal aspect of such costs. This study argues that election timing impinges on the extent to which the audience cost mechanism works, and consequently, on state conflict behavior. While competitive elections are central to the political accountability (...) inherent in a democracy, voters typically lack enough opportunities to punish unsatisfactory leaders in a timely way, because of fixed election timing, and also may disregard foreign policy missteps that occurred in the distant past. Democratic leaders therefore have an incentive to choose strategically, with the electoral calendar in mind, when selecting a form of conflict behavior. Leaders can retreat from their demands without paying high audience costs when the upcoming election is in the distant future. To test this argument, the authors conduct a natural experiment featuring territorial disputes between Russia and two Baltic republics – Estonia and Latvia. Despite the commonalities in the disputes, as well as in their political systems and socioeconomic backgrounds, the governments of the two Baltic countries showed a sharp contrast in their diplomatic decisions. This paper argues that only the temporal gap in electoral timing can explain this variation, imparting the ironical implication that frequent democratic elections can obstruct peaceful conflict resolutions, and that excessive democratization may well hinder the very goal of peace.

Intervention studies on sedentary older adults have demonstrated that commencing physical exercise at an older age has a positive effect on brain structure. Although this suggests that older athletes with lifelong sports training have larger gray matter volume in some brain regions compared to age-matched non-athletes, evidence in the literature is scarce. Moreover, it remains unclear whether a larger GMV is associated with training intensity or period of training in life. To address these gaps in the literature, we compared regional (...) brain GMV between 24 older athletes and 24 age-matched non-athletes. The period of sports training and the current training time of the athletes were assessed. Both groups were evaluated for physical activity intensity as well as cognitive and motor performance. Although no group differences were noted in cognitive and motor performance, athletes reported higher physical activity intensity than non-athletes. Whole-brain structural analysis revealed a significantly larger GMV in several brain regions in athletes. Notably, the GMV of the precuneus in athletes was positively correlated with earlier commencement of sports training and training duration but was negatively correlated with current training time. Our findings demonstrate that early-commenced and continued sports training predicts structural maintenance of the precuneus in old age. Our results also suggest that excessive training time in old age may have a negative impact on the GMV of the precuneus; thereby delineating how the precuneus is associated with lifelong sports training in older athletes.

This study employs fMRI to examine the neural substrates of response to cognitive training in healthy old adults. Twenty Japanese healthy elders participated in a 4-week program and practiced a verbal articulation task on a daily basis. Functional connectivity analysis revealed that in comparison to age- and education-matched controls, elders who received the cognitive training demonstrated increased connectivity in the frontotemporal regions related with language and memory functions and showed significant correlations between the behavioral change in a linguistic task and (...) connectivity in regions for goal-oriented persistence and lexical processing. The increased hippocampal connectivity was consistent with previous research showing efficacious memory improvement and change in hippocampal functioning. Moreover, the increased intra-network connectivity following cognitive training suggested an improved neural differentiation, in contrast to the inter-network activation pattern typical in the aging brain. This research not only validates the relationship of functional change in the frontal and temporal lobes to age-associated cognitive decline but also shows promise in turning neural change toward the right direction by cognitive training.

Prenant appui sur l’œuvre du philosophe japonais Nakai Masakazu (1900-1952), cet article expose une conception de la photographie qui permet de sortir le déploiement technique de l’horizon des fins catastrophiques. Il s’en dégage les linéaments d’une philosophie qu’on peut qualifier à proprement parler de photographique où se mêlent des schémas issus du bouddhisme et de la théorie marxienne du reflet.

Since the end of the 1970s, the Japanese concept of ma has often been used in the west to signify an aesthetics of distance. This paper is a reverse exploration whose aim is to understand how this term appeared in the critical discourse in Europe, but also in Japan with philosopher Nakai Masakazu. It shows that this concept is a recent elaboration of Japanese thought, which emerged from a dialogue with German phenomenology and Heidegger in particular.

This paper situates Watsuji Tetsurō’s philosophical conception of “climate” within the context of both its historical development and its critical reception by Watsuji’s Kyoto School peers. Part one moves across lecture notes, articles, and book editions to historicize and contextualize climate within its four aspects of development: cultural history, hermeneutic phenomenology, “relational in-betweenness,” and socio-historical development. Part two develops critical responses to each of these four aspects by Watsuji’s Kyoto School peers: Nishida Kitarō, Miki Kiyoshi, Hayashi Tatsuo, Tosaka Jun, and (...) Nakai Masakazu. It ends by briefly considering how these historical and critical considerations might serve as guideposts for contemporary philosophical reconstructions of climate. (shrink)
