Building on Nietzsche’s view of power, Foucault developed an original analysis of power by making use of concepts like “disciplinary power,” “bio-power,” “governmentality,” etc.; however, existing studies have not sufficiently examined his reading of Nietzsche’s works on this topic. Therefore, in order to clarify the connection between the two, this article examines Foucault’s reading of Nietzsche in detail. Firstly, this article examines the notion of “force” which Foucault recognized is at the center of Nietzsche’s view of power, and will explicitly (...) shows its conceptual determinations. In doing so, this paper will also clarify related notions such as “event,” “body” and “history,” and thus bring to light the general principle of force. In addition, Foucault focused on the point at which Nietzsche—using these principles—radically reinterpreted a central concept of human intellectual activity, namely knowledge. Therefore, this article secondly examines how knowledge is formed under the principle of force, and explicitly shows the general mechanism of knowledge. Finally, the article explains that Nietzsche’s view of power is understood by Foucault as the duality between force and knowledge; in other words, as an ontology of force. (shrink)

Let f be a computable function from finite sequences of 0ʼs and 1ʼs to real numbers. We prove that strong f-randomness implies strong f-randomness relative to a PA-degree. We also prove: if X is strongly f-random and Turing reducible to Y where Y is Martin-Löf random relative to Z, then X is strongly f-random relative to Z. In addition, we prove analogous propagation results for other notions of partial randomness, including non-K-triviality and autocomplexity. We prove that f-randomness relative to a (...) PA-degree implies strong f-randomness, hence f-randomness does not imply f-randomness relative to a PA-degree. (shrink)

We consider weak theories of concatenation, that is, theories for strings or texts.

Previous work suggests that Asians allocate more attention to configuration information than Caucasian Americans do. Yet this cultural variation has been found only with stimuli such as natural scenes and objects that require both feature- and configuration-based processing. Here, we show that the cultural variation also exists in face perception—a domain that is typically viewed as configural in nature. When asked to identify a prototypic face for a set of disparate exemplars, Japanese were more likely than Caucasian Americans to use (...) overall resemblance rather than feature matching. Moreover, in a speeded identity-matching task, Japanese were more accurate than Americans in identifying the spatial configuration of features (e.g., eyes). Together, these findings underscore the robustness of culture’s influences on cognition. (shrink)

Enhancing synchronization among people when synchronization is lacking is believed to improve their social skills, learning processes, and proficiency in musical rhythmic development. Greater synchronization among people can be induced to improve the rhythmic interaction of a system with multiple dancing robots that dance to a drum beat. A series of experiments were conducted to examine the human–human synchrony between persons that participated in musical sessions with robots. In this study, we evaluated: (a) the effect of the number of robots (...) on a subject’s ability to synchronize with an experimenter; (b) the effect of the type of robot synchrony, namely, whether the robots did or did not represent the subject’s rhythm; (c) the effect of an in-sync and out-of-sync robot on a subject’s behavior. We found that: (a) three robots increased the level of synchronization between the subject and experimenter and their enjoyment level; (b) robots may induce greater synchronization between the subject and experimenter by reproducing the rhythms of not only the experimenter but also of the subject compared to when only the experimenter’s rhythms had been reproduced; (c) the robots in-sync had greater influence on the natural rhythm of the subject.

To compare two randomness notions with each other, we ask whether a given randomness notion can be defined via another randomness notion. Inspired by Yu's pioneering study, we formalize our question using the concept of relativization of randomness. We give some solutions to our formalized questions. Also, our results include the affirmative answer to the problem asked by Yu in a discussion with the second author, i.e., whether Schnorr randomness relative to the halting problem is equivalent to Martin‐Löf randomness relative (...) to all low 1‐generic reals.

Previous studies have shown that viewing cute pictures leads to performance improvement in a subsequent fine motor task. We examined the beneficial effects of viewing cute pictures in a more complex sporting skill by comparing three conditions and two tests. The participants, all of whom were college basketball players, performed 16 free throws in each condition. In the no-pressure test, male participants improved performance after viewing pictures of baby animals but not after adult animals and no pictures. In the pressure (...) test, no significant improvement was observed. For female participants, the cuteness-viewing effect was not observed in both tests. The results suggest that viewing cute pictures may improve performance during basketball free throws in a low-pressure situation by narrowing the breadth of attentional focus and inducing approach motivation and caregiving behaviors.

While directors’ task boundaries are usually ambiguous, some of their activities or behaviors clearly constitute their formal duties, whereas others are usually perceived as organizational citizenship behavior. Applying identity theory, we present a theoretical model that demonstrates one of the key drivers for directors to engage in OCB with a focus on their role identity. We argue that an individual director’s role identity is one of the key factors that motivate directors to engage in OCB. Furthermore, we propose that two (...) board-level contingencies, board capital, and informal board hierarchy order, can moderate the effect of directors’ role-identity salience on their OCB. That is, low levels of board capital and directors’ higher positions in a board’s informal hierarchy enhance directors’ motivation to engage in OCB. (shrink)

Kierstead showed that every computable marriage problem has a computable matching under the assumption of computable expanding Hall condition and computable local finiteness for boys and girls. The strength of the marriage theorem reaches or if computable expanding Hall condition or computable local finiteness for girls is weakened. In contrast, the provability of the marriage theorem is maintained in even if local finiteness for boys is completely removed. Using these conditions, we classify the strength of variants of marriage theorems in (...) the context of reverse mathematics. Furthermore, we introduce another condition that also makes the marriage theorem provable in, and investigate the sequential and Weihrauch strength of marriage theorems under that condition.

The purpose of this article is to initiate a philosophical discussion about the ethical component of professional competence in nursing from the perspective of Brazilian nurses. Specifically, this article discusses professional competence in nursing practice in the Brazilian health context, based on two different conceptual frameworks. The first framework is derived from the idealistic and traditional approach while the second views professional competence through the lens of historical and dialectical materialism theory. The philosophical analyses show that the idealistic view of (...) professional competence differs greatly from practice. Combining nursing professional competence with philosophical perspectives becomes a challenge when ideals are opposed by the reality and implications of everyday nursing practice. (shrink)

Because of the importance of board members’ resource provision and monitoring, a substantial body of research has been devoted to ascertaining how directors can be incented to perform their responsibilities. We use social exchange theory to empirically examine how board members’ resource provision and monitoring are affected by their perceptions of the CEOs’ trustworthiness. Our findings suggest that board members’ perceptions of the CEO’s ability, benevolence, and integrity have different effects on the board members’ resource provision and monitoring. Our results (...) further suggest that board members’ governance behaviors are moderated by the board’s performance evaluation practices. (shrink)

When building personal relationships, it is important to select optimal partners, even based on the first meeting. This study was inspired by the idea that people who smile are considered more trustworthy and attractive. However, this may not always be true in daily life. Previous studies have used a relatively simple method of judging others by presenting a photograph of one person’s face. To move beyond this approach and examine more complex situations, we presented the faces of two people confronted (...) with each other to participants and asked them to judge them from a third-person perspective. Through three experiments, participants were asked to judge which of the two persons was more appropriate for forming alliances, more trustworthy, or more attractive, respectively. In all experiments, images were shown for a short or a long time. In all three experiments, the results showed that participants were more likely to choose persons with happy faces than those with neutral, sad, or angry faces when the image presentation was short. Contrarily, the facial expressions did not affect those judgments when the image presentation was long. Instead, judgments were correlated with personality estimated from the model’s neutral face in a single-person presentation. These results suggest that although facial expressions can affect the judgments of others when observing two-person confrontations from a third-person perspective, when participants have more time to elaborate their judgments, they go beyond expressions.

While empathy is considered a critical determinant of the quality of medical care, growing evidence suggests it may be associated with both one’s own positive and negative moods among healthcare professionals. Meanwhile, sense of coherence plays an essential role in the improvement of both psychological and physical health. Reportedly, individual SOC reaches full stability after around age 30. The aim of this study was first to evaluate the mediatory role of SOC on the association between empathy and individual moods among (...) 114 healthcare professionals in a general hospital, and then to examine the moderating effect of age on this association. Participants completed a range of self-report demographic questionnaires, Empathy Process Scale, the 13-item Antonovsky’s SOC, and Profile of Mood States. Findings showed that SOC mediated the relations between empathy and both POMS-Vigor and POMS-Depression. Notably, moderated mediation analysis revealed that there was a significant interaction on self-vigor mood in healthcare professionals. The indirect effect of empathy on self-vigor mood through SOC was significant at over mean age “32.83.” Although there was no significant interaction with age regarding the indirect effect of empathy on self-depression mood, in the sub-category level analysis of empathy, we found a significant interaction item [age × empathy for other’s negative affect ] on SOC. This indirect effect was also significant at over mean age “32.83.” Taken, together, the current study highlighted the significant mediator of SOC on that empathy amplifies self-vigor mood and attenuates self-depression mood as a protective factor among the Japanese healthcare professionals. Some components of these processes may depend on the moderating role of age, indicating that we may need to consider the SOC development with age for more effective empathy performance interventions among healthcare professionals.

While positive psychology has drawn increasing interests among researchers in the SLA literature recently, little is known with respect to the relationship between positive psychology and mental processes during L2 reading. To bridge the gap, the present study investigated whether and how positive psychology (self-efficacy) influences word reading strategies during L2 sentence reading. Based on previous studies, eye-movement patterns with first-fixation locations closer to the beginning of a word can be characterized as an attempt to process the word with a (...) local strategy, whereas first-fixation locations farther away from the beginning and closer to the center of a word can be considered as an attempt to use a global strategy. Eye movements of a group of Japanese learners of English (N = 59) were monitored, and L2 reading self-efficacy was used to assess the participants’ positive belief towards their L2 reading skills. Based on B. L. Fredrickson’s (1998) broaden-and-build theory, we predicted an effect of L2 reading self-efficacy on participants’ first-fixation locations. Results from mixed-effects regression showed that while reading strategies depended in part on other factors such as L2 reading proficiency and word properties, L2 self-efficacy influenced reading strategy. The present data suggest that while more self-efficacious L2 readers prefer a more efficient global strategy, attempting to read the word as a whole word, less self-efficacious L2 readers tend to employ a local strategy, focusing more on sublexical information. These findings lend support to the broaden-and-build theory in the context of L2 processing. The present study has implications for how positive psychology works along with L2 proficiency in the development of strategic selection during reading. (shrink)
